Kidneys and right lobe but in contradistinction to normal tissues treatment without admission is known as order diamox 250 mg online, cancerous of liver are shielded with lead to reduce the dose to these tissues cannot recover from the insult medications you should not take before surgery cheap 250mg diamox with visa. Cell cycle times vary widely (12-217 hours) but are relatively constant for a specific tumor type medications during breastfeeding generic diamox 250mg free shipping. Mustard gas used in World War I medications bladder infections purchase diamox 250mg with mastercard, was found to have Normal cells may be classified as: tremendous effect on bone marrow suppression. Speed of cell To prevent recurrence of the tumor division is the same compared to a normal cell. Doubling Effective chemotherapy is designed to kill selectively time varies depending upon the specific type of the the malignant cells without producing serious tumor. The duration of the on S phase methotrexate 1 2 cycle from M phase to M phase is called generation 5 fu time. Dividing tumor cells are most sensitive taxanes to cytotoxic agents whereas cells in the G0 are G nitrosoureas 0 relatively insensitive. Proper understanding of cell cycle has evolved legitimate synergistic combinations of drugs x Type and dose schedule of agents. This will enhance the tumor cell kill and minimize the risk of drug It is observed that antitumor agents kill a constant resistance. This is called log kill (g) Drug dose is adjusted according to the tolerance hypothesis. Chapter 30 RadiotheRapy, ChemotheRapy, immunotheRapy and GenetheRapy 513 x Because of toxicity, drug dose and duration of B. Antimetabolites act by inhibiting essential therapy cannot be increased when single agent metabolic processes that are required for synthesis chemotherapy is used. Important similarity and mechanism of action: members of this group are paclitaxel (taxol) and A. These are often hormone responsive tumor and also increase called radiomimetic drugs as they share some anabolic processes. It provides a better Intraperitoneal: Systemic administration is more measure of potential toxicity than body weight. There is minimal change of surface area of cancer, (ii) as an adjunct to radiation therapy, (iii) during entire course of therapy compared to body as a neoadjuvant therapy, used for advanced disease weight. Nomogram is used for calculating body following which additional treatment is planned, (iv) surface area of adults (p. Minor agents are highly toxic to the erythropoietic system, complications like nausea, vomiting, alopecia, bone marrow in particular. The drugs are mostly glossitis should not preclude full treatment metabolized in the liver and are excreted through the protocol. Explaining the situation clearly helps and as such, any source of infection is to be treated. It is due to stimulation of chemo receptor trigger zone which secretes neurotransmitters the following considerations have led to the idea that (serotonin, dopamine and histamine) to activate the vomiting host immune response can prevent tumor growth: center. They also increase the autosomal dominant inheritance pattern have been described sensitivity of tumor cells to cytotoxic drugs. Three types of genes (oncogenes, tumor suppressor genes x Any single agent therapy is often ineffective. Point mutation, deletion and insertion are the important x Immunotherapy is more effective against tumors changes observed in malignancy. Oncogenes are dominant whereas tumor suppressor genes Modulation of Immune System (Biological (p. Familial cancer account for Active immunotherapy (to induce host immune response). Passive immunotherapy (immunologically active Oncogenes regulate cell growth in a positive fashion. It enhancement leading to rejection of tumor can occur when needs two mutational events (point mutation, deletions) for the following conditions are fulfilled: its loss of function (recessive). Telomerase: Reactivation of telomerase activity to restore Cytokines provide stimulatory signals important for T telomere sequences is absent in a normal cell. Such cytokine milieu can be enhanced by significant telomerase activity become immortal and turn local injection at the tumor site to promote the acquisition into cancer cells. One attempt is to remove progress with this technology to prevent squamous cell the oncogene product or to block its function. Alternatively, cancer, colon cancer, ovarian epithelial cancer and lung one can use antisense oligonucleotides in an attempt to block cancer. Cytokine gene transfer tumor mArkErs to tumor cells stimulates a systemic immune response and destroy tumor cells. It is then released trials are in progress in patients with squamous cell carcinoma, into the blood where from it can be detected. Tumor marker is useful in screening, diagnosis x Its measurement either in the blood or urine and management of a case and for follow-up. Ideally the antigen (tumor marker) of disease (ovarian carcinoma) progression and level should represent the tumor volume correctly. A list of tumor markers is given x the assay should be inexpensive and acceptable. Teletherapy is used to deliver to homogeneous radiation dose to a large volume of tumor. Tumor tissue recovers from radiation damage more slowly compared to normal tissue. There may be localized or systemic radiation reactions for which appropriate therapy is needed. Drugs commonly used are alkylating agents, antimetabolites, antibiotics, plant alkaloids, and hormones. Toxic effects varies from slight to more severe one, even to the extent of death (p. Taxol (paclitaxel and docetaxel) is a powerful antineoplastic agent that disrupts microtubule function (polymerization) (see p. It gives a synergistic effect by acting at different cell sites and reduces the development of drug resistance (see p. Growth factors or granulocyte colony-stimulating factor are used to prevent hemorrhagic toxicity of chemotherapy. It is useful in screening, diagnosis and management of cases and also for follow up. Gene therapy to the tissues at risk by insertion of normal copies of genes is a way forward. Autocrine function is explained when Factors: Factors are substances that modulate cell function a regulating substance produced by a cell and proliferation by acting upon the cell membrane act upon the receptor on the same cell. They act locally (unlike the hormones) by modulates the function of the same cell autocrine and paracrine mechanism. Once the structure for cell receptors and it stimulates the cellular physiological of natural hormones is defined, it becomes possible response. These substances another substance binding on its receptor without eliciting can be used: a biological response. There is a blockage of receptor To diagnose the functional integrity of endocrine response. Because of relative lack of receptor specificity, an antagonist for one class of hormone can have an antagonistic To modify the abnormal function of the endocrine effect on another class of hormone. Antagonists may have adverse effects apart from the To alter the normal function to gain objectives. While, many natural hormones are not easily available in adequate quantities, with advanced cellular FuNctioN technology, many such products are manufactured by A cell function is modulated by any of the three ways: synthetic, semisynthetic or hybridization. However, the result may consequently the gonadal secretion (hypogonadotropic not be unequivocal and as such, requires cautious hypogonadal state). Induction of ovulation: It is suitable in cases with commoN PreParatioNs idiopathic hypogonadotropic hypogonadism who table 31. The benefits include less need of cycle monitoring, However, the improvement is only limited during high pregnancy and livebirth rates. But the and suppression of spermatogenesis (Femal) size comes back to previous state after the drug (male) (see Chapter 29). The gonadotropins, used effects are hot flushes, vaginal dryness, dyspareunia, widely today, are derived from urine obtained from headache and depression (menopause-like symptoms, postmenopausal women.

High responders are those women who have detection of diminished ovarian reserve (dor): exaggerated response in follicular development. Variety of chemical Progesterone should be used for luteal phase support mediators like cytokines, vascular epidermal growth factor (see p. Due to this reason the word "pseudomenopause" seems misnomer; while the estrogen level is reduced but unlike menopause, the gonadotropins remain static in base levels. The net result is production of an hypoestro Chest X-ray (shielding the pelvis), monitoring of genic state.

The remaining 5%-10% of enterococcal infections are due to Enterococcus faecium medications you cant crush order 250 mg diamox with mastercard, which is increasingly resistant 19 to vancomycin and is now considered a major nosocomial pathogen symptoms 0f parkinson disease buy genuine diamox on-line. Enterococci typically are associated with causing urinary tract infections medicine sans frontiers buy diamox 250mg, intra-abdominal and pelvic sepsis symptoms ringworm order genuine diamox online, surgical wound infections and bacteremia medicine express 250 mg diamox with mastercard, in descending order of frequency symptoms breast cancer buy diamox 250 mg amex. However, they now are emerging as highly-resistant 19 organisms and nosocomial pathogens. Enterococci have been identified as the third most common cause of nosocomial, 20 hospital-acquired pneumonia. Enterococci are intrinsically resistant to a number of antibiotics and antibiotic classes. They do not possess exotoxins or enzymes that allow invasion and destruction of tissues. They can, however, readily acquire resistance genes that are capable of transfer to other bacteria. Resistant enterococcus can be isolated from patients who have been institutionalized for long periods of time. Other risk factors for acquiring a resistant enterococcal infection include severity of underlying illness, presence of invasive devices, prolonged antibiotic use and prior colonization. Those at higher risk include immunosuppressed hosts such as renal dialysis, transplant and oncology patients. Treatment of serious infections due to beta-lactam resistant gram-positive organisms. Treatment of serious infections due to gram-positive organisms in patients with serious beta-lactam allergies. Prophylaxis for endocarditis for certain procedures based on American Heart Association recommendations. Routine surgical prophylaxis unless the patient has a severe allergy to beta lactam antibiotics. Treatment of one positive blood culture for coagulase-negative staphylococcus if other blood cultures drawn at the same time are negative. Continued empiric use in patients whose cultures are negative for beta-lactam resistant gram-positive organisms. Prophylaxis for infection or colonization of indwelling central or peripheral intravenous catheters. Routine prophylaxis for patients on continuous ambulatory peritoneal dialysis or hemodialysis. Treatment of infection due to beta-lactam sensitive gram-positive microorganisms in patients with renal failure (for ease of dosing schedule). Enterococcus has developed intrinsic resistance to many antibiotics, including cephalosporin antibiotics. They exhibit low-level resistance to aminoglycosides, which can be overcome by adding a cell-wall active agent such as ampicillin or vancomycin. These combinations can provide a bactericidal effect, sometimes referred to as a synergistic effect. Resistance to beta-lactams occurs secondary to either enzyme production or altered penicillin-binding proteins. Beta-lactamase producing strains for Enterococcus faecalis, which are typically rare, can be treated with ampicillin/sulbactam + an aminoglycoside. Enterococcus faecium, which produce an enzyme different from penicillinase that is not inhibited by penicillin, are now commonly resistant to many beta-lactams although there are reports of success with combination 20, 26 therapy using double and or triple combination regimens. Enterococci develop 19, 27 resistance via three phenotypes, which are outlined in Table 2. A comprehensive group of individuals, which may consist of infection control, infectious disease, medical, surgical, nursing, microbiology, pharmacy, epidemiology, quality assurance, administration staff and all other pertinent entities, should develop its own protocols for each individual institution. For line-related bacteremia, simply removing the intravenous device may be sufficient. Surgical debridement and drainage may be adequate for cases of soft tissue infections, surgical site infections and abscesses. Urinary tract infections may respond spontaneously or with removal of indwelling catheters. For severe infections such as endocarditis and meningitis, utilization of bactericidal antibiotics is advised. Reasons for limited clinical data include lack of comparator arms in clinical trials, high mortality rates with advanced illness and complex treatment vii requirements. Nitrofurantoin, ampicillin, and amoxicillin have been effective for treating urinary tract infections because they achieve high concentrations in urine. However, nitrofurantoin should be used with caution in the elderly and those with impaired renal function. Quinupristin-dalfopristin is a streptogramin that is active against Enterococcus faecium but not Enterococcus faecalis. Linezolid, an oxazolidinone, has activity against both Enterococcus faecium and Enterococcus faecalis. Treatment options, though limited, are available and newer agents are being studied. Besides quinupristin-dalfopristin and linezolid, use of older agents, usually in combination, have been effective. Strict adherence to infection control policies and consultation with infectious disease specialists are important. These problems can sometimes become severe or life-threatening and can lead to death. These problems may happen anytime during treatment or even after your treatment has ended. Call or see your healthcare provider right away if you develop any new or worsening signs or symptoms, including: Lung problems cough shortness of breath chest pain Intestinal problems diarrhea (loose stools) or more frequent bowel movements than usual stools that are black, tarry, sticky, or have blood or mucus severe stomach-area (abdomen) pain or tenderness Liver problems yellowing of your skin or the whites of your eyes dark urine (tea colored) severe nausea or vomiting bleeding or bruising more easily than normal pain on the right side of your stomach area (abdomen) Hormone gland problems headaches that will not go away or unusual headaches urinating more often than usual eye sensitivity to light hair loss eye problems feeling cold rapid heartbeat constipation increased sweating your voice gets deeper extreme tiredness dizziness or fainting weight gain or weight loss changes in mood or behavior, such as decreased feeling more hungry or thirsty than usual sex drive, irritability, or forgetfulness Kidney problems decrease in your amount of urine swelling of your ankles blood in your urine loss of appetite Skin problems rash painful sores or ulcers in your mouth or in your nose, throat, or genital area itching fever or flu-like symptoms skin blistering or peeling swollen lymph nodes Problems can also happen in other organs and tissues. Call or see your healthcare provider right away for any new or worsening signs or symptoms, which may include: chest pain, irregular heartbeat, shortness of breath, swelling of ankles confusion, sleepiness, memory problems, changes in mood or behavior, stiff neck, balance problems, tingling or numbness of the arms or legs double vision, blurry vision, sensitivity to light, eye pain, changes in eyesight persistent or severe muscle pain or weakness, muscle cramps low red blood cells, bruising Infusion reactions that can sometimes be severe or life-threatening. Signs and symptoms of infusion reactions may include: chills or shaking dizziness itching or rash feeling like passing out flushing fever shortness of breath or wheezing back pain Rejection of a transplanted organ. Your healthcare provider should tell you what signs and symptoms you should report and monitor you, depending on the type of organ transplant that you have had. Getting medical treatment right away may help keep these problems from becoming more serious. Your healthcare provider may treat you with corticosteroid or hormone replacement medicines. Talk to your healthcare provider about birth control methods that you can use during this time. A significant number of these develop from potentially malignant lesions like leukoplakia, erythroplakia, lichen planus and oral 3 Senior Professor, Department of submucous fibrosis. Every year it molecular biology, and optical physics have come together accounts for more than 300,000 cases world-wide, more than to radically change the way diagnosis is arrived at or 30,000 cases in the United States and more than 3,000 cases confirmed which in earlier times was difficult to achieve 3. Advanced optical systems for in vivo imaging, such as cancer examination were reported to be 83. The sensitivity for use of reflectance endomicroscopy, are designed to image cell and methylene blue dye(used to detect gastric, prostrate and stromal morphology for noninvasive clinical diagnosis in bladder cancers) when used for oral cancer screening was real time. However, the contrast between neoplastic and 90%, the specificity 69%, positive predictive value 74%, and normal tissues is often too low to be of any clinical value 1. Optical coherence tomography is a new high resolution Photodiagnosis and tissue fluorescence imaging optical technique capable of providing cross sectional imaging of biological tissue. They utilize a fibre optic probe Malignancy related biochemical and morphologic changes with an imaging depth range of 2-3mm. It provides real time perturb tissue absorption, fluorescence and scattering structural imaging based on low coherence interferometry, properties. Thus biochemical information can be obtained by using broadband light to provide cross sectional, high measuring absorption/reflectance, fluorescence or Raman resolution subsurface tissue images13. Several light based adjunctive aids have specificity in diagnosis statistics can reach 82 and 90% been employed to aid in the diagnosis of oral cancer which respectively 14. However significant challenges to the use of include chemiluminescence, tissue fluorescence imaging, diagnostic spectroscopy include the often low signal to noise and tissue fluorescent spectroscopy. Under this light, dysplastic tissues with enlarged method that uses optical illumination and ultrasonic nuclei, highlighted by dehydration with acetic acid, appear detection to produce images of deep tissues based on their "aceto white3, 8. The development of a molecular-based cancer and potentially malignant epithelial lesions is 80. Velscope operates on this principle by emitting a cone of Raman spectroscopy is another technique that has been used light in the blue spectrum(400-460nm) into the oral cavity to study cancer-related chemical changes in both cancerous causing flurophores in the oral tissue to excite and fluoresce tissues as well as biofluids. Saliva contains many which can be viewed through a narrow band filter embedded macromolecules such as proteins and nucleic acids giving a in the instrument. However, Raman spectra from saliva are values are significantly lower ranging from 30% to 92% and inherently weak, making interpretation difficult. This test works by Nanodiagnostics, defined as the use of nanotechnology for placing the brush on one spot and rotating it until it produces clinical diagnostic purposes, was developed to meet the hemorrhagic spots. The sample obtained is then fixed on a demands of clinical diagnostics for increased sensitivity and glass slide and sent to the laboratory 8, 10. The use of nanotechnologies for diagnostic applications shows great promise to meet the A multicenter study comparing oral brush biopsy with rigorous demands of the clinical laboratory for sensitivity scalpel biopsy reported specificity rates to be 100% for and cost-effectiveness. Emerging Trends Nanotechnology refers to the area of science devoted to the Recently, an increased amount of effort has been made to manipulation of atoms and molecules leading to the develop less invasive early diagnostic modalities for oral production of structures in the nanometer scale size range cancer, of which the in vivo high-resolution imaging of oral (often 100nm or smaller) which retain unique properties. As nanoparticles exist in the same size as proteins or cells, it is suitable for biotagging and Nanodiagnostics promise increased sensitivity, multiplexing can be used as diagnostic biomarkers 3, 15, 16, 17. However cost of nanotreatment and are applied particularly in cancer imaging studies. They have biocompatibility are the major hindrances to the use of nano enough surface area to combine therapeutic agents and particles. Recently their use has also been implicated in near infrared imaging (700 1000nm) as imaging probes 18. Despite tremendous advances in the configuration for developing the processes that lead to field of diagnosis of oral cancer, many challenges still cancer. Keeping ourselves abreast with the emerging and identify multiple nucleotide polymorphic sites in large diagnostic trends is the need of the hour. Nanowires having the unique properties of selectivity and specificity can be designed to sense molecular markers of malignant cells.

Annual Dental Visits by Children in Medicaid Managed Care (Aged 4 through 21 Years) and Child Health Plus (Aged 4-18 Years) New York State: 2002-2004 70 2002 2003 2004 55 40 53 47 44 25 41 38 35 10 Medicaid Managed Care Child Health Plus Source: New York State Managed Care Plan Performance Report on Quality treatment 1 degree av block safe diamox 250mg, Access to Care withdrawal symptoms cheap diamox 250mg on line, and Consumer Satisfaction medicine gustav klimt diamox 250 mg low cost, New York State Department of Health treatment keloid scars order diamox cheap online, December 2005 There were 27 health plans enrolled in the Medicaid Managed Care Program during 2004 medications ending in pril purchase generic diamox canada, 20 of which (74%) provided dental care services as part of their benefit package medications available in mexico buy 250 mg diamox with visa. For the seven plans not offering dental services, enrollees have access to dental services through Medicaid fee-for service. Children having an annual dental visit varied by health plan, from a low of 10% of all children aged 4 through 21 years in one plan to a high of 53% of all children covered under another plan. The statewide average of 44% of children having an annual dental visit in 2004 exceeded the 2004 national average of 39% of all children in Medicaid Managed Care. All health plans (27 plans) participating in Child Health Plus provided dental services in 2004, with the percentage of children 4-18 years of age receiving an annual dental visit found to similarly vary by health plan enrollment. Children having an annual dental visit varied from a low of 40% of all children aged 4-18 years to a high of 72% of all children. Within the same health plan, the percentage of children receiving an annual dental visit was higher for children enrolled in Child Health Plus compared to those enrolled in Medicaid Managed Care in all but two cases. In one health plan, 40% of all children covered under Medicaid Managed Care and Child Health Plus received an annual dental visit (40% under each plan), while in another plan, a slightly higher percentage of children in Medicaid Managed Care (47%) had an annual dental visit, compared to children covered under Child Health Plus (45%).

Twelve (12) plans provide coverage in only one geographic or service area of the State, while only one plan provides statewide coverage; the remainder of plans is available to eligible individuals in two or more service areas of the State. Use of Dental Rehabilitation Services by Children Under 21 Years of Age Children under 21 years of age with congenital or acquired severe physically-handicapping malocclusions are provided access to appropriate orthodontic services under the Bureau of Dental Healths Dental Rehabilitation Program and are eligible to receive both diagnostic/ 82 evaluative and treatment services. Medicaid eligible children receive orthodontic services through the Physically Handicapped Childrens Program as part of the Medicaid fee-for-service program, but only if services are determined to be medically necessary for treatment of physically handicapping malocclusions or qualifying congenital defects, as defined by law. During the 2003-2004 Program fiscal year st th (December 1 November 30), excluding New York City, a total of 5,379 children received services under Medicaid fee-for-services, with total expenditures reaching slightly over $7. Children not eligible for Medicaid are covered under the Public Health Law. During the 2003-2004 Program fiscal year, a total of 1,581 children outside of New York City were provided services under the Public Health Law at a total cost of $1. During 2004, an additional 12,000 children in New York City received services either as part of the Medicaid fee-for-service program or under the Public Health Law. Local Health Departments and Community-Based Health Centers New York State relies on its local health departments to promote, protect and improve the health of residents. Under Article 6 of the State Public Health Law, New York State provides partial reimbursement for expenses incurred by local health departments for approved public health activities. Article 6 requires dental health education be provided as a basic public health service, with all children under the age of 21 underserved by dental health providers or at high risk of dental caries to have access to information on dental health. Local health departments either provide or assure that education programs on oral health are available to children. Local health departments also have the option of providing dental health services targeted to children less than 21 years of age who are underserved or at high risk for dental diseases. Fifty-one of 57 counties and New York City received funding during 2004 to provide dental education, while 15 of 57 counties and New York City received funding for the provision of dental health services. Article 28 of the State Public Health Law governs hospitals and Diagnostic and Treatment Centers in New York State. Article 28 facilities may provide, as part of their Certificate of Need, dental outpatient services. These services include the provision of preventive and emergency dental care under the supervision of a dentist or other licensed dental personnel. A key focus area in New York State Department of Healths Oral Health Plan is to work with Article 28 facilities to: increase the number of Article 28 facilities providing dental services across the State and approve new ones in areas of highest need; encourage Article 28 facilities to establish comprehensive school-based oral health programs in schools and Head-Start Centers in areas of high need; identify barriers to including dental care in existing community health center clinics and in hospitals not currently providing dental care; and to encourage hospitals in underserved areas to provide dental services. As of 2004, 193 of 215 (90%) community-based health centers (139 of 155) and local health departments (54 of 60) in the State had an oral health component. Individuals using grantee services during 2004 were mainly racial/ethnic minorities: 30% Black/African American, 32% Hispanic or Latino, 5% Asian, and 24% White, with 27% of all users reportedly best served in a language other than English. The majority of grant service users were adults 35-64 years of age (33%), school-aged children 5-18 years of age (25%), young adults 25-34 years of age (14%), and children under 5 years of age (11%). Approximately one-fourth of service recipients were uninsured, 46% were Medicaid-eligible, 18% had private health insurance, and 2. Based on data collected from all 50 grantees, services were provided to over 1 million individuals during the year, with 195,162 individuals 84 (19%) receiving dental services either directly or through referral, with 2. After taking into account age limitations on the use of these two dental services, 35% of children aged 1 to 21 years received fluoride treatments and 30% of children aged 5 to 15 years had sealants applied. Of the 41,546 individuals receiving services during the year: 60% were male, 45% were between 35-64 years of age, 15% were between 25-34, 14% were 19-24 years of age, 13% were school-aged children between 5 and 18 years of age, 9% were under 5 years of age, 55% were Black/ African American 29% were Hispanic or Latino individuals (29%), nearly 96% reported incomes 100% and below the Federal Poverty Level, 40% were uninsured, and 57% were Medicaid eligible. Slightly over 10% of individuals receiving services from Healthcare for the Homeless Programs during 2004 received dental services, with an average of 2 dental encounters per person. Taking into account age limitations on the receipt of fluoride treatments and application of dental sealants, 8. Of the 8,162 individuals receiving services during 2004: 63% were female, 30% were school-aged children between 5 and 18 years of age, 20% were children under 5 years of age, 13% were between 25-34 years of age, 10% were between 35-44 years of age, 57% were Hispanic or Latino, 35% were Black/African American, 79% reported incomes 100% and below the Federal Poverty Level, 25% were uninsured, 53% were Medicaid eligible, 13% had private health insurance, and 4% were enrolled in Child Health Plus B. Taking into account age limitations on the receipt of fluoride treatments and application of dental sealants, 25. Each contractor provides a different array of services that may include outreach, primary and preventive medical and dental services, transportation, translation, health education and linkage to services provided by other health and social support programs. The services are designed to reduce the barriers that discourage migrants from obtaining care, such as inconvenient hours, lack of bilingual staff and lack of transportation. Eight (8) contractors provide dental services either directly or through referral, while 3 provide services through referral only. Of those receiving dental services from the contractor, slightly over a third (35.

Of those receiving dental services, all received an oral examination, 18% received prophylactic services, 15% had restorative services, 3% received emergency services, and one child (0. Taking into account age limitations on the receipt of fluoride treatments and application of dental sealants, 14. Dental services, although provided by 49 of 50 grantees either directly or through referral, have not been as widely utilized by program recipients as other types of program services. American Indian Health Program Under Public Health Law Section 201(1)(s). The American Indian Health Program provides access to primary medical care, dental care and preventive health services for approximately 15,000 Native Americans living on reservations. Health care is provided to enrolled members of nine recognized American Indian Nations in New York State through contracts with three hospitals and one community health center. The program covers payment for prescription drugs, durable medical equipment, laboratory services and contracts with Indian Nations for on-site primary care services. Comprehensive Prenatal-Perinatal Services Network the Perinatal Networks are primarily community-based organizations sponsored by the Department of Health whose mission is to organize the service system at the local level to improve perinatal health. The Networks work with a consortium of local health and human service providers to identify and address gaps in local perinatal services. The networks also sponsor programs targeted to specific at-risk members of the community, and respond to provider needs for education on special topics, such as screening for substance abuse among pregnant women, smoking cessation or cultural sensitivity training. Each of the 15 Perinatal Networks targets a region, ranging in size from several Health Districts in New York City to large multi-county regions in rural Upstate areas. Over the past decade, Perinatal Networks have become involved in a range of initiatives, including dental care for pregnant women. Several 91 Networks include information on dental health during pregnancy, periodontal disease and birth outcomes, and prevention of early childhood caries in their newsletters and on their websites. Other Networks either have or are in the process of establishing oral health subcommittees to address the oral health needs of pregnant women and young children in their catchment area and in applying for grant funding for innovative dental health education and service delivery programs. Rural Health Networks the Rural Health Network Development Program creates collaborations through providers, non profits, and local government to overcome service gaps. These collaborative efforts have led to many innovative and effective interventions such as, development of community health information systems, disease management models, education and prevention programs, emergency medical systems, access to primary and dental care, and the recruitment and retention of health professionals. These dental health programs are designed to: Assess and monitor the oral health status of children and adults; Provide guidance on policy development and planning to support oral health-related community efforts; Mobilize community partnerships to design and implement programs directed toward the prevention and control of oral diseases and conditions; Inform and educate the public about oral health, including healthy lifestyles, health plans, and the availability of care; Ensure the capacity and promote the competency of public health dentists and general practitioners and dental hygienists; Evaluate the effectiveness, accessibility and quality of population-based dental services; Promote research and demonstration programs to develop innovative solutions to oral health problems; and Provide access to orthodontic care for children with physically handicapping malocclusions. The programs and initiatives funded by the Bureau of Dental Health fall within three broad categories: 1. Preventive Services and Dental Care Programs Preventive Dentistry for High-Risk Underserved Populations the Preventive Dentistry for High-Risk Underserved Populations Program addresses the problems of excessive dental disease among children residing in communities with a high proportion of persons living below 185% of the federal poverty level. A total of 25 projects have been established at local health departments, dental schools, health centers, hospitals, diagnostic and treatment centers, rural health networks, and in school-based health centers to provide a point of entry into the dental health care delivery system for underserved children and pregnant women. Services include dental screenings, the application of dental sealants, referrals, and other primary preventive dental services for an estimated 260,000 children and 1,500 pregnant women across the State. Program activities include: Establishment of partnerships involving parents, consumers, providers and public agencies to identify and address oral health problems, identify community needs, and mobilize resources to promote fluoridation, dental sealants and other disease prevention interventions. In conjunction with prenatal clinic visits, pregnant women can receive dental examinations and treatment services, as well as oral health education. Additional funds were available for a special two-year campaign to foster program expansion and increase the number of sealants that the Preventive Dentistry contractors were able to apply. Fluoride Supplement Program the Fluoride Supplement Program targets children in fluoride-deficient areas of the State and consists of a School-Based Fluoride Mouth Rinse Program for elementary school children and a Preschool Preventive Tablet Program for three and four year old children in Head Start Centers and Migrant Childcare Centers. Innovative Dental Services Grants the Bureau of Dental Health, New York State Department of Health supports 7 programs to assess the effectiveness and feasibility of several different innovative interventions for 93 addressing oral health problems. Interventions include the use of mobile and portable systems, fixed facilities, and case management models. Collaborative approaches are used to improve community-based health promotion and disease prevention programs and professional services to ensure continued progress in oral health. A total of $768,077 in innovative dental services grants supports the following activities: Establishment or expansion of innovative service delivery models for the provision of primary preventive care and dental care services to underserved populations in geographically isolated and health manpower shortage areas; Development of case management models to address the needs of difficult to reach populations; and Development of partnerships and local coalitions to support and sustain program activities. Preventive Dentistry Program for Deaf/Handicapped Children the State Department of Health Preventive Dentistry Program for Deaf/Handicapped Children is operated under contract with New York Citys Bellevue Hospital. The program provides health education and treatment services for deaf children receiving services at the Bellevue dental clinic and at nearby schools for the deaf in Manhattan. Through the program, deaf and hearing impaired children are introduced to dental equipment and procedures, while their parents are taught basic preventive dental techniques and are given treatment plans for approval. A hearing-impaired dental assistant employed by the Program provides services to the children. Comprehensive School-Based Dental Programs Oral Health Collaborative Systems Grants support school-based primary and preventive care services. School-based health centers are located within a school, with primary and preventive health services provided by a nearby Article 28 hospital, diagnostic and treatment center, or community health center. During 2004, these centers screened 9,189 students, applied dental sealants for 2,185 students, and provided restorative services to 484 students. Of the children receiving dental services, all had an oral examination, 97% of 5 to 15 year olds had dental sealants applied, 18% of children received prophylactic services, 15% had fluoride treatments, 15% had restorative services, 3% received emergency services, and one child (0. Dental Health Education Dental Public Health Residency Program the Dental Public Health Residency Program is designed for dentists planning careers in dental public health and prepares them, via a broad range of didactic instruction and practical experience, for a practice in dental public health. The residency program is accredited by the Commission on Dental Accreditation, a specialized accrediting body recognized by the Council on Post Secondary Accreditation, and the United States Department of Education. The Program is currently affiliated with the School of Public Health, State University at New York, Albany; Montefiore Medical Center, Bronx; and Eastman Dental Center, University of Rochester. The New York State Oral Health Coalition identified research and surveillance as one of four priority areas to be addressed by the Coalition over the next three years.

A statistically significant increase in the incidence of thyroid tumors was also observed in female rats medicine 4 the people generic diamox 250mg mastercard, but this finding was not considered biologically significant (U treatment plant cheap 250 mg diamox. The average dose levels for the study were 138 or 277 and 238 or 477 mg/kg/day for males and females medications used to treat fibromyalgia purchase diamox master card, respectively treatment yersinia pestis discount 250mg diamox with mastercard. Three additional groups of animals served as matched (20/sex/group) symptoms 9 days post ovulation best buy for diamox, colony (99 males and 98 females) symptoms quad strain order diamox online now, and positive (100/sex/group) controls. Comparable survival rates and weight gains were observed between the treated and control groups, except for the high-dose females. The incidence of hepatocellular carcinomas was significantly increased in males and females in both the low and high-dose groups when compared to controls. Many of the male mice in the low-dose group that did not develop hepatocellular carcinoma had nodular hyperplasia of the liver. The incidence of kidney epithelial tumors was comparable between treatment and control groups. In three different studies, 10-week-old mice were administered chloroform by gavage 6 days per week for 80 weeks, followed by a 13 to 24-week observation period. Kidney tumors were statistically higher in high-dose male mice than in controls, while all other tumor incidences were comparable to control. Sprague-Dawley rats (50/sex/group) were administered concentrations of 0 or 60 mg chloroform/kg/day in toothpaste by gavage, 6 days/week for 80 weeks. No significant differences in mortality were observed between treated and control animals. A marginal decrease in body weight gain (about 10%) was observed in both treated males and females when compared to controls. A statistically significant decrease in relative liver weight was observed in treated females. Histologic examination of the liver revealed only minor changes, with no severe fatty infiltration, fibrosis, or marked bile duct abnormalities reported. The incidence of moderate to severe glomerulonephritis was reported to be slightly increased in treated males. The chemical was given orally in a toothpaste base in gelatin capsules, 6 days/week for 7. A group of 16 male and 16 female dogs received toothpaste base without chloroform and served as the vehicle control group. Eight dogs of each sex served as an untreated group and a final group of 16 dogs (8/sex) received an alternative nonchloroform toothpaste. Four male dogs (one each from the low and high-dose chloroform groups, the vehicle control group, and the untreated control group) and seven female dogs (four from the vehicle control group and three from the untreated control group) died during the study. The most prominent microscopic effect observed in the liver was the presence of "fatty cysts," which were described as aggregations of vacuolated histiocytes. The fatty cysts were observed in the control and treated dogs, but were larger and more numerous. The prevalence of moderated or marked fatty cysts was 1/27 in control animals, 9/15 in low-dose animals, and 13/15 in high-dose animals. Nodules of altered hepatocytes were observed in both treated and control animals, and therefore were not considered related to treatment. No other treatment-related nonneoplastic or neoplastic lesions were reported for the liver, gall bladder, cardiovascular system, reproductive system, or urinary system. Calculated dose levels were 0, 32, 64, 97, 145, 290, or 436 mg/kg/day based on reported water intakes. At week 1, a significant decrease in body weight was observed in the 900, 1,800, and 2,700 ppm chloroform treatment groups; however, all body weights of the treated animals were comparable to controls after week 1. On days 30, 60, and 90, ten animals from each treatment group were sacrificed for gross and microscopic pathologic examination, as well as for measurement of organ fat:organ weight ratios. Histological examination of the liver revealed mild centrilobular fatty changes in the 1,800 and 2,700 ppm groups. On day 30, reversible fatty changes in the liver were observed at doses as low as 400 ppm chloroform. This study was an interim report of a 2-year bioassay conducted by Jorgenson et al. Male Osborne-Mendel rats and female B6C3F1 mice were exposed to chloroform in drinking water (0, 200, 400, 900, or 1,800 mg/L) for 1-6 months. The time weighted average doses, based on measured water intake and body weights, were 0, 19, 38, 81, or 160 mg/kg in rats and 0, 34, 65, 130, or 263 mg/kg in mice. An additional group of matched controls received the same water volume as the high-dose groups. In male rats, some changes were observed in body weight and in some hematological and serum biochemical parameters, but the authors judged these changes to be a secondary effect of reduced water intake. Gross and microscopic pathology findings in the rats generally were slight or mild in severity, were not dose related, and either appeared adaptive (occurred in rats sacrificed after 30 or 60 days, but not in those sacrificed after 90 days) or were sporadic (by 15 nature and/or incidence) and not considered treatment-related. In mice, mortality within the first 3 weeks was significantly increased in the two highest dose groups (130 and 263 mg/kg/day), but was comparable to controls after that time. A significant increase in liver fat in mice was noted at doses of 65 mg/kg/day and higher at 3 months, and at doses of 130 and 263 mg/kg/day at 6 months. Time-weighted average doses, based on measured water intake and body weights, were 0, 19, 38, 81, or 160 mg/kg/day for rats and 0, 34, 65, 130, or 263 mg/kg/day for mice. An additional group of animals that served as controls was limited to the same water intake as the high-dose groups. The number of animals in the dose groups (from low to high) was 330, 150, 50, and 50 for rats and 430, 150, 50, and 50 for mice. In male rats, survival at 104 weeks was greater in exposed groups than in controls. In female mice, survival was similar to controls following an initial decline in survival of mice that refused to drink for the first week of the study. A statistically significant dose-related increase in the incidence of kidney tumors (tubular cell adenomas and adenocarcinomas) was observed in male rats in the high-dose group (160 mg/kg). A statistically significant increase in the incidence of lymphomas and leukemias and a statistically significant decrease in the incidence of adrenal cortical adenomas, adrenal pheochromocytomas, and thyroid c-cell adenomas was observed in male rats in the high-dose group when compared with controls. However, study authors suggested that the incidence of renal tumors was the only endpoint that was biologically significant with respect to chloroform treatment (U. Chloroform in the drinking water did not increase the incidence of hepatocellular carcinomas in female B6C3F1 mice. The combined incidence of hepatocellular adenomas and carcinomas was 2% in the high-dose group compared with 6% in the control groups. Based on this reexamination, it was found that animals exposed to average doses of 81 or 160 mg/kg/day of chloroform displayed low-grade renal tubular injury with regeneration, mainly in the mid to deep cortex. The changes included faint basophilia, cytoplasmic vacuolation, and simple hyperplasia in proximal convoluted tubules. In some animals, single-cell necrosis, mitotic figures, and karyomegaly were also observed. Hyperplasia was visualized as an increased number of nuclei crowded together in tubule cross-sections. These changes were observable in the 160 mg/kg/day dose group at 12, 18, and 24 months, and in the 81 mg/kg/day dose group at 18 and 24 months. Cytotoxic changes were not seen in either of the lower dose groups (19 or 38 mg/kg/day). The effect of the vehicle on the hepatotoxicity of chloroform was evaluated using male and female B6C3F1 mice. Doses of 0, 60, 130, or 270 mg/kg/day in corn oil or in 2% emulphor were administered via gavage for 90 days. Based on measurements of serum enzyme levels, serum and tissue triglyceride levels, and histological examination of the livers, the authors concluded that hepatotoxic effects were enhanced by the administration of chloroform via corn oil versus chloroform administered in an aqueous suspension. The authors suggested that the cause may be absorption kinetics or interaction between chloroform and the corn oil vehicle (U. Male and female Wistar rats were administered chloroform in drinking water at concentrations of 0 or 2,900 mg/L for 72 weeks. Concentrations of chloroform were then reduced to 1,450 mg/L for an additional 113 weeks until all animals had died (approximately 185 weeks). The average dose for males and females was approximately 200 or 150 mg/kg/day, respectively (U. Treated females (but not males) showed a statistically significant increase in the incidence of hepatic neoplastic nodules, and both males and females had a statistically significant increase in the incidence of hepatic adenofibrosis. The potential carcinogenicity of chloroform was evaluated in mice following oral administration via oil or water. When administered in oil, 250 mg chloroform/kg/day produced 17 an increased incidence in tumors (tissue not specified), whereas there were no increases in the incidence of tumors observed in mice treated with 15 mg/kg/day. No increases in tumor incidence were observed in mice treated with up to 42 mg/kg/day via drinking water (U. DeAngelo (1995) exposed male F-344 rats to chloroform in drinking water for 100 weeks. Interim sacrifices of groups of 6 animals were performed at 26, 52, and 78 weeks, and the final sacrifice at 100 weeks included 50 animals per group. At each time point, liver and kidney were examined for gross and microscopic lesions. In kidney, a wide variety of chronic nephropathies were observed in both control and exposed animals. The incidence of these nephropathies was not considered to be different than spontaneous background rates. Nasal toxicity of chloroform in male F-344 rats and female B6C3F1 mice following a 1-week inhalation exposure. Examination of the nasal passages 18 revealed that chloroform caused a complex set of responses in the ethmoid turbinates, predominantly in rats. These lesions were most severe peripherally and generally spared the tissue adjacent to the medial airways. The only change noted in the mouse was increased cell proliferation without osseous hyperplasia. Animals were 3 exposed to concentrations of chloroform ranging from 2-300 ppm (10-1460 mg/m) for 6 hours per day, either 5 or 7 days per week, for up to 13 weeks (90 days). All animals were examined for histological lesions of liver, kidney, and nasal epithelium. Exposure to chloroform caused histopathological lesions in liver, kidney, and nasal epithelium of both rats and mice. Lesions in liver were characterized by scattered vacuolated hepatocytes and necrotic foci, sometimes with inflammation, mainly in the centrilobular and midzonal regions. Renal lesions occurred primarily in the epithelial cells of the proximal convoluted tubules in the cortex. Changes included vacuolation, a basophilic appearance, tubule cell necrosis, and enlarged cell nuclei. Nasal lesions were characterized as atrophy of olfactory epithelium, mainly in the ethmoid portion of the nasal passage. In most cases, histological effects in liver and kidney were not observed until exposure levels were about 30 ppm or higher. However, atrophy of the nasal epithelium was observed in rats at the lowest exposure level tested (2 ppm). Histological changes were generally accompanied by statistically significant increases in Labeling Index, although not always at exactly the same exposure level. These increases in Labeling Index are interpreted as evidence that the cytotoxic responses in these tissues triggers a regenerative hyperplasia. Increased cell proliferation was not found in either sex of rats exposed to chloroform for 6 weeks and held (without exposure) until week 13, suggesting that cell proliferation is dependent on the presence of chloroform and represents a regenerative response to cytotoxicity. Summary of chloroform-induced cytotoxicity and cell proliferation via inhalation Liver Kidney Nasal epithelium Exposure Histopath. Groups of male and female rats and mice were exposed to target chloroform vapor concentrations of 0, 10, 30, or 90 ppm or 0, 5, 30, or 90 ppm, respectively, 6 hours/day, 5 days/week for 104 weeks. To avoid lethality in the high-dose groups, mice in the 30-ppm and 90-ppm groups were exposed to chloroform concentrations of 5 and 10 ppm for 2 weeks each and then 30 ppm for 100 weeks or 5, 10, and 30 ppm for 2 weeks each and then 90 ppm for 98 weeks, respectively. The authors reported that both male and female rats and mice showed necrosis and metaplasia of the olfactory epithelium and goblet cell hyperplasia of the respiratory epithelium. Ossification was observed in the nasal turbinate and in the nasal septum of rats and mice, respectively, at the lowest exposure levels. Statistically significant increases in the incidence of overall renal cell adenoma and renal cell carcinoma were observed in male mice in the 30 (7/50) and 90 (12/48) ppm groups when compared with controls (0/50). The overall incidence rates of renal cell carcinoma were statistically significantly increased in males in the 90-ppm group (11/48) when compared with controls (0/50). There were no statistically significant changes in tumor incidence for female mice or for male or female rats in any exposure group. These authors observed cytotoxicity and hyperplasia in the kidneys of male mice exposed to 30 or 90 ppm throughout a 90-day exposure period. These observations are consistent with the hypothesis that cytotoxicity and regenerative hyperplasia are key events in the neoplastic response to chloroform. Significantly decreased food consumption and body weights were noted in dams administered 126 mg/kg/day or greater. Fetotoxicity, acute 21 toxic nephrosis, hepatitis, and maternal death occurred in animals administered 316 mg chloroform/kg/day and higher.

Cancer deaths represent incidence indirectly, since they refect the failure of treatment as well as the occurrence of the disease. For those forms of cancer for which available treatments are less effective, for example lung and stomach cancer, deaths refect incidence quite accurately. Since 1950, the incidence of stomach cancer has declined by more than 50% in most th countries. Lung cancer, by contrast, rose dramatically throughout the 20 century, more than 10-fold in North America for instance, although inci dence in men began to decline in the 1980s, as it had earlier in the United Kingdom (Miller, 1999). Thus, cancer epidemics tend to rise to a peak and then recede over several decades. As a consequence, the time periods involved tend to conceal the epidemic nature of the trend. Predictions of cancer prevalence, incidence, and mortality are important bases for cancer control activities. Together with predictions for other dis eases, they are useful for setting national health priorities. As indicated in Chapter 1, major increases in cancer incidence and mortality are predicted for the developing countries. Over one-third of patients expe rience clinical range anxiety and/or depression (Epping-Jordan, 1999). Surprisingly, disease severity, prognosis, and type of treatment do not seem to have a large impact on psychosocial adjustment to cancer. However, patients who can fnd a sense of meaning in what is happening to them and who can achieve mastery over their illness adjust well to their cancer. Family income loss, social isolation, family tensions, and adverse effects on daily functioning in the family may follow closely on the occurrence of cancer. Similarly, health care providers are not immune to the psychosocial effects of caring for people with cancer. Workers who frequently see sick and dying patients, or who cannot provide assistance to their patients in the manner they want, are at risk for "staff burn-out". This syndrome is charac terized by emotional exhaustion and de-personalization of the patient, and has been linked to job absenteeism, insomnia, substance abuse and physical complaints (Ullrich, Fitzgerald, 1990). Indirect costs arise from loss of productivity as a result of the illness and premature death of those affected. Direct costs may be estimated fairly readily in situations where the nature and extent of services provided to cancer patients are known. Calculation of indirect costs, however, involves making assumptions concerning both expected future earnings and a discount rate to convert potential earnings into a current amount. Beyond these numbers, the common reality, especially in poor areas, is a profound economic family crisis. A diagnosis of cancer in one of the adults in a family may lead not only to the loss of a source of income, but also all too frequently to exhausting the familys remaining income and resources in seeking treatments. Perhaps saddest of all are the futile frantic searches and large amounts of money paid by the family for treatments that can not prolong the life of the family member with advanced cancer. If families feel abandoned by their formal health care system, they may spend their remaining resources seeking assistance from well-meaning or unscrupulous individuals who falsely promise to help. This approach offers the greatest public health potential and the most cost-effective long-term method of cancer control. Early detection Increasing awareness of the signs and symptoms of cancer contributes to early detection of the disease. Where tests for cancer of spe cifc sites are available, and facilities are appropriate, screening of apparently healthy individuals can disclose cancer in early or precursor stages, when treatment may be most effective. Diagnosis and treatment Cancer diagnosis calls for a combination of care ful clinical assessment and diagnostic investigations. Once a diagnosis is confrmed, it is necessary to ascertain cancer staging to evaluate the exten sion of the disease and be able to provide treatment accordingly. Cancer treatment aims at curing, prolonging useful life and improving quality of life. Treatment services should give priority to early detectable tumours and potentially curable cancers. In addition, treatment approaches should include psychosocial support, rehabilitation and close coordination with palliative care to ensure the best possible quality of life for cancer patients. Palliative care In most of the world, the majority of the cancer patients present with advanced disease. Effective approaches to palliative care are available to improve the quality of life for cancer patients. Cancer control research is briefy dis cussed in Chapter 8, while Chapter 9 reviews cancer surveillance, the basis for cancer control planning, monitoring and evaluation. Prevention not only focuses on the risks associated with a par ticular illness or problem but also on protective factors. Action on tobacco use is universally needed, but the priorities accorded to other components of the programme will depend on the results of a situ ation analysis of the country concerned, covering the actual and forecast burden of cancer cases in the country, and the estimated proportion of potentially preventable cases. A broad range of health promotion activities are appropriate to cancer control and these are examined in detail at the end of this chapter. Such dependence syndromes are described as a cluster of behavioural, cognitive and physiological phenomena that develop after repeated substance use and that typically include a strong desire to take the drug, diffculties in control ling its use and persistence in drug use despite harmful consequences. Young people usually encounter the practice among their peers, and may then take up the habit themselves. Typically, tobacco use begins through social contacts, but the habit is reinforced by the development of physiological dependence, derived from the nicotine content of tobacco. Cessation of tobacco use in those who are addicted produces withdrawal symptoms, typical of other addictions. Such symptoms can appear within hours of cessation and persist for weeks or months. On the Indian subcontinent and adjacent parts of central Asia, for example, tobacco is often mixed in a quid with betel nut and lime, and retained in the mouth for long periods of time. In Sudan, the use of smokeless tobacco in the form of snuff, called toombak, is widespread. Toombak is dipped in the saliva of the oral cavity or, less frequently, sniffed into the nasal cavities. Today, in most parts of the world, cigarette smoking is the most common form of tobacco use. Now, the epidemic is extending into many developing countries, where smoking has been encouraged by the marketing policies of national and multinational tobacco companies. The longer a person has been smoking and the more packs per day smoked, the greater the risk. If a person stops smoking before a cancer develops, the risk remains at the same level or may even increase. Even after ten years, the ex-smokers risk still does not equal the lower risk of a person who never took up smoking. Cigar smoking and pipe smoking are almost as likely to cause lung cancer as cigarette smoking. A substantial proportion of cancer in the oral cavity, pharynx, larynx, pancreas, kidney, oesophagus, bladder, and probably stomach and cervix 26 27 Prevention uteri is also attributable to tobacco. Moreover, smoking is responsible for Prevention a large amount of chronic lung disease and contributes heavily to cardio vascular disease. Tobacco smoke contains approximately 4000 chemical substances, of which at least 438 can produce cancer. The most common cancer causing agents in tobacco are the polyaromatic hydrocarbon and nitroso compounds. The development of cancer in particular organs depends upon the sites that come into contact with the chemical constituents of tobacco and tobacco smoke. The lungs are the principal target when tobacco smoke is inhaled; when tobacco is chewed or kept in the mouth, the cheek, tongue, and other parts of the oral cavity are affected. The increased risk at other sites is probably a result of carcinogens being absorbed into the blood stream from the lungs and transported to the relevant organ. Non-smokers who breathe in the smoke of others (also called second-hand smoke or environ mental tobacco smoke) are at increased risk for lung cancer. Workers who have been exposed to tobacco smoke in the workplace are also more likely to get lung cancer. Action against tobacco the need for effective global action against the tobacco epidemic is urgent, especially in developing countries. Hundreds of millions of people cur rently use tobacco, and tens of millions will suffer severely impaired health and shortened lives. Effective tobacco control begins with the realization that tobacco is powerfully addictive. The task of containing the spread of tobacco use and assisting individuals to overcome the addiction may be achieved in a number of ways, but must always take account of the wide spread, longstanding, and deeply ingrained nature of the habit and the strong social factors that encourage it, as well as the political imperatives of many countries, especially those with a major indigenous tobacco industry. Many countries have undertaken health promotion and health education programmes to inform people of the adverse effects of tobacco. Decades of experience demonstrate that health promotion and edu cation measures are insuffcient to combat the tobacco problem. For more effective results, health promotion and education must be accompanied by other actions, particularly legislation, tobacco taxes and tobacco cessation 26 27 Prevention programmes, that will reduce the social acceptability of tobacco use. Much Prevention depends on people having adequate understanding of both the short-term and long-term consequences of the habit, but simply imparting this knowl edge is not enough. Equally important is the cultivation of attitudes that will be effective against smoking or other use of tobacco. These attitudes may refect personal values regarding short-term effects (on personal appearance, for instance) as much as concern about long-term health damage. Young people are sensitive to the way in which tobacco remnants and the odour of smoke on their person and their clothes may affect their social relation ships. In addition, they need psychosocial resistance skills, particularly in situations where there is substantial pressure to initiate or continue tobacco use. Overall, direct efforts to infuence the behaviour of the individual with regard to tobacco have had, and will probably continue to have, only lim ited success. Mass education, however, and development of public attitudes against tobacco use have encouraged many cigarette smokers to give up the habit. In North America, where cigarette smoking is in decline, most people who have given up cigarettes report that they did so "on their own"; they took personal responsibility for their action. People with higher levels of education and greater concern about health, especially physicians and other health professionals, tend to be the frst to give up smoking. As they acquire knowledge of the threat to health, they are also the frst to give up the habit. This diffusion of the tobacco epidemic extends throughout society, until it is the least well educated, and most socially disadvantaged segments of society that retain the habit, and the consequences to their health. The trend to resist smoking can also be accelerated by specifc counselling and advice from physicians. Professional health workers should be infuenced by the policies of the health services in which they work; they should avoid tobacco use of any sort in order to set an example to others. Government action can do much to encourage people to give up cigarettes, by prohibiting smoking in workplaces, restaurants, and public buildings, and on public transport, for example, and by controlling the advertising of tobacco products, providing the regulations are enforced. Valuable use can be made of the media for mass education about the dangers of smoking and means of avoiding or overcoming the habit. In communities where smoking has become socially unacceptable and non-smokers are in the majority, there are major incentives not to smoke. Government economic policy towards tobacco is highly relevant to indi 28 29 Prevention vidual and mass education against tobacco use. The powerful commercial Prevention interests involved in production and distribution of tobacco products exploit peoples dependence on tobacco in order to maintain sales. Their arguments include the preservation of "free" trade and of individual "freedom" to enjoy tobacco, as well as the need to avoid economic problems in the form of loss of jobs and material investment in the tobacco industry. Strong polit ical and social initiatives to counteract these pressures are vital. Government action regarding land use, subsidies, taxes, and other leverage on prices also has a profound infuence on the spread of tobacco use. The stringency of measures taken by some countries to prevent use of other dependence-pro ducing substances contrasts with their policies on tobacco, yet tobacco is responsible for far more deaths than heroin and cocaine combined.
