Diagnosis As a generic group, the diagnosis of congenital vascular lesions is usually self-evident on clinical examination. When they afect the mandible or the maxilla, a radiolucent lesion with a honeycomb pattern and distinct margins is expected. Diferentiation between congenital hemangiomas and congenital vascular malformations can be difcult and occasionally impossible. Laser therapy is another accepted form of primary treatment of selected vascular lesions. Because the margins of these lesions are often ill defned, total elimination may not be practical or possible. Encephalotrigeminal Angiomatosis (Sturge-Weber Syndrome) Encephalotrigeminal angiomatosis, or Sturge-Weber syndrome, is a noninherited neurocutaneous syndrome that includes vascular malformations with characteristic distribution. Treatment Spontaneous involution during early childhood is likely for congenital hemangiomas. If these lesions persist into the later years of childhood, involution is improbable and defnitive treatment may be required.

The term pyogenic granuloma is a misnomer because it does not produce pus, nor does it represent granulomatous infammation (Table 4-2). Clinical Features Pyogenic granulomas occur mostly in the second decade of life and are most commonly seen on the attached gingiva (75%), where they presumably are caused by the presence of calculus or foreign material within the gingival crevice ures 4-13 to 4-15). Some granulomatous infammation may be related to vessel trauma and subsequent abnormal Treatment Excision to Excision to repair. Tese lesions present as red-blue discrete and asympperiosteum or periosteum or tomatic tumescences that can be excised relatively easily. Tese lesions may be seen at any age and tend to occur more commonly in females than in males; they are seen in up to 5% of pregnancies. Histopathology Microscopically, pyogenic granulomas are composed of lobular masses of hyperplastic granulation tissue ure 4-16). Some scarring may be noted in some of these lesions, suggesting that occasionally maturation of the connective tissue repair process may occur. Diferential Diagnosis Clinically, this lesion is similar to peripheral giant cell granuloma, which also presents as a red gingival mass. A peripheral odontogenic or ossifying fbroma may be another consideration, although these tend to be much lighter in color. Recurrence is occasional and is believed to result from incomplete excision, of puberty and pregnancy may modify the gingival reparafailure to remove etiologic factors, or reinjury of the area.

The most frequent cause in children prostate cancer essential oils 0.2mg flomax, however prostate cancer icd-9 buy generic flomax 0.2mg on line, is iatrogenic, resulting from vascular thrombosis after surgeries for congenital heart disease, shunting procedures for hydrocephalus, or central catheterization for venous access. Why is a generous mediastinal shadow on the radiograph much more worrisome in a teenager than an infantfi Wilms tumor, hepatoblastoma, and adrenal cortical carcinoma are associated with hemihypertrophy either as part of Beckwith-Wiedemann syndrome or in isolation. Acute leukemia, chronic myeloid leukemia, chronic myelomonocytic leukemia, Hodgkin disease, and non-Hodgkin lymphoma. Solid tumors rarely metastasize to the spleen to the point of causing splenomegaly. What are the predictors of malignancy in the pediatric patient with peripheral lymphadenopathyfi A common clinical problem is determining which patients with enlarged lymph nodes require biopsy for diagnosis. In a study of 60 patients, risk for malignancy increased with increasing size (>1 cm), increasing number of adenopathy sites, and increasing ages (! Supraclavicular location, abnormal chest radiograph, and fixed nodes were also significantly predictive of malignancy. Although there are no absolute criteria, in most centers, packed red blood cells are given when a patient has a hemoglobin level of less than 8. Granulocyte transfusions may be effective in neutropenic patients with a refractory infection caused by a gram-negative organism. Leukocyte depletion removes other white blood cells that would increase the risk for febrile transfusion reactions, alloimmunization, and the transmission of cytomegalovirus. What are the most common symptoms experienced by oncology patients receiving end-of-life carefi Parents report that these symptoms are managed effectively in less than one third of children. As compared with adults, twice as many children die in hospitals during the final stages of disease, and half of them are on a ventilator. What are the frequencies of relative incidence of the childhood cancers in the United Statesfi Cancer ranks a distant second, accounting for 10% of deaths in children younger than 15 years. Accidents account for nearly 45% of deaths among this age group; congenital anomalies rank third, at 8%, and homicide ranks fourth, at 5%. Currently, the available epidemiologic data do not support an association between cellular phone use and brain tumors. Theses studies are complicated by many factors, including recall bias (patients with brain tumors recalling cell phone exposure differently than subjects without brain tumors), difficulties in estimating actual radiofrequency exposure, and incomplete follow-up of study subjects. Multiple studies have demonstrated that low birthweight (<1000 g) is a risk factor for hepatoblastoma. Presently, it is not known whether this is due to other factors associated with low birthweight, such as hyperalimentation use, or the low birthweight itself. Diethylstilbestrol, which was used to prevent spontaneous abortion, has been associated with an increased risk for vaginal cancer in the female offspring. It has also been reported that there is a 10-fold increased risk for monoblastic leukemia in the infants of mothers who smoke marijuana. It has been suggested that sedatives and a number of nonhormonal drugs are transplacental carcinogens, but this is not proved. It also has not been proved that cigarette smoke and the use of oral contraceptives are transplacental carcinogens. In vitro, ultrasound has been shown to cause cell membrane changes, and thus concern has been expressed regarding potential effects on embryogenesis and prenatal and postnatal development. However, in a study of all deaths from leukemia in Swedish children over a 16-year period, no association with prenatal ultrasound was found. Of note, the only known association of prenatal ultrasound with alterations in development has been a preference for left-handedness. Do children living near electrical power lines have an increased risk for developing cancerfi Increased risk: Patients with Down syndrome, congenital immunodeficiency syndrome, exposure to ionizing radiation; sibling of patient with acute lymphoblastic leukemia 3. Chemotherapy phases: Induction (to achieve remission), delayed intensification, maintenance 4. Survival (if in standard risk group) >80% at 5 years after completion of therapy 5. Leukocyte count (mm3) n <10,000: 45% to 55% n 10,000 to 50,000: 30% to 35% n >50,000: 20% Hemoglobin (g/dL) n <7. Immunophenotyping is also useful and involves the determination of Bor T-cell lineage, with maturity or immaturity of cells. In boys, after a full course of chemotherapy with remission, testicular involvement is a common site of relapse, occurring in up to 10% of cases. In older boys and teenage boys, there is a higher incidence of T-cell disease than in girls. T-cell disease is associated with adverse prognostic factors (high white blood cell count, hepatosplenomegaly, and mediastinal masses) and alone carries a poorer prognosis. In girls, ovarian relapse is very rare, although it is difficult to diagnose after bone marrow relapse. In both leukemias, African American ethnicity is associated with a poorer outcome. Although the reasons are not known, these differences may be the result of either host or leukemia characteristics. Chromosomal translocation abnormalities, specifically t(8;14), t(9;22), and t(4;11) 4. In the United States, what are the four most common types of pediatric leukemia, and about how many children are diagnosed each year with each typefi In addition to leukemia, what other diagnoses should be considered when evaluating a child who shows symptoms of pancytopeniafi The two most consistent prognostic factors are age and elevation of presenting white blood cell count. Children younger than 1 year or older than 10 years old have a worse prognosis, as do those with a presenting white blood cell count of 50,000/mm3 or greater. Identifying patients at higher risk is important so that more aggressive or novel therapy can be considered. Other than age at diagnosis and white blood cell count, what factor has the greatest prognostic impact on long-term survivalfi A better prognosis is seen in patients who have a brisk initial response to therapy. The Berlin-Frankfurt-Munster group found a similar prognosis in patientsfi who had less than 1000 blasts/mm3 in the peripheral blood after 7 days of prednisone. What is the acute risk for a very elevated blast count noted at the time of the initial diagnosis of leukemiafi Leukocytapheresis is sometimes used to reduce the blast count before initiating therapy, but its impact on improving outcome remains unproved. Testicular disease is accompanied by painless testicular swelling (usually unilateral). Patients with testicular disease require irradiation in addition to intensive retreatment with chemotherapy. A number of endocrinologic complications can occur, including growth hormone deficiency, hypothyroidism, hypogonadism, impaired fertility, and premature ovarian failure. Children are also at risk for deficits in attention, memory, and intelligence quotient. Finally, children receiving cranial radiation are at risk for developing a second malignant neoplasm. The Philadelphia chromosome, discovered in Philadelphia in 1960 by Nowell and Hungerford, was the first clonal cytogenetic abnormality (a balanced translocation between chromosomes 9 and 22) described in leukemia. The result is a new fusion gene that codes for a tyrosine kinase with increased enzymatic activity. Its normal cell of origin remains unclear, with the predominance of evidence indicating a B or T lymphocyte. However, the cells alone are not pathognomonic of Hodgkin disease and may be seen in infectious mononucleosis, non-Hodgkin lymphoma, carcinomas, and sarcomas. Hodgkin lymphoma, like non-Hodgkin lymphoma, is classified according to the stage of disease and histology, as in the Ann Arbor System. Patients with documented fever, involuntary weight loss of more than 10%, or night sweats are considered to have B disease. Intractable pruritus may also be a symptom, but it is not among the B symptoms used for staging. Pathologic staging refers to biopsy-proven disease in a given region and usually involves a staging laparotomy and splenectomy to determine the extent of disease. The prognosis for children with Hodgkin disease is excellent in that most are cured. The classification of lymphomas has evolved over time, but an international effort has brought consistency to diagnosing these diverse cancers. The common classification is further divided into B-cell lymphoma (precursor B-cell lymphoblastic lymphoma or leukemia, Burkitt lymphoma, diffuse large-B cell lymphoma, and mediastinal [thymic] large-B cell lymphoma) and T-cell lymphoma (precursor T-cell lymphoblastic lymphoma or leukemia, anaplastic large cell lymphoma, and peripheral T-cell lymphoma, unspecified). The bone marrow blast percentage is used to differentiate Band T-cell precursor leukemia from lymphoma. If the bone marrow blast percentage is greater than or equal to 25%, the diagnosis of leukemia is given. If the blast percentage is less than 25% and the patient has other sites of malignant disease, the diagnosis of lymphoma is given. As compared with adults, aggressive, high-grade lymphomas occur more frequently in children. The three most common types are Burkitt lymphoma, lymphoblastic lymphoma, and large cell lymphoma. Patients typically present in adolescence with nodal involvement and may have involvement of extranodal sites including the skin and soft tissues. Eosinophilic granuloma is a lytic tumor of bone that is accompanied by pain and sometimes swelling. Its histology is identical to that of Langerhans cell histiocytosis, with which it is now classified. Biopsy of an isolated eosinophilic granuloma is often curative, although lesions may also regress spontaneously. Other features include skin rashes that resemble seborrheic dermatitis, chronic otitis externa, lymphadenopathy, hepatosplenomegaly, pancytopenia, neurologic deficits, and pulmonary disease. Mild forms of the disease tend to wax and wane even without treatment, whereas disseminated disease is often resistant to therapy. Older children (>1 year): Most tumors are infratentorial (cerebellar or brainstem) 3. Gold standard for diagnosis: Magnetic resonance imaging with and without gadolinium enhancement 5. Back pain, extremity weakness, and/or bowel and bladder dysfunction suggestive of spinal cord lesions or metastases 95. Supratentorial tumors include tumors of the cerebrum, basal ganglia, thalamus, and hypothalamus. These tumors can show signs of increased intracranial pressure, such as headache and vomiting. In addition, these tumors may be accompanied by focal deficits, such as memory loss, weakness, and visual changes. Which common parameters should be closely monitored in a child after resection of a brain tumorfi Alternatively, some patients may develop a cerebral salt-wasting syndrome after resection. Which cranial nerve abnormality is most common in children showing signs of increased intracranial pressure as the result of a posterior fossa tumorfi Diencephalic syndrome is the constellation of symptoms that result from the presence of a hypothalamic tumor: euphoria, emaciation, and emesis. Parinaud syndrome is the result of increased intracranial pressure at the dorsal midbrain, causing downgaze, papillary dilation, and nystagmus. Both serum and cerebrospinal tumor a-fetoprotein and human chorionic gonadotropin should be obtained.

These injections crus is incised through the vestibular mucosa directly and blanch and elevate the mucoperichondrium. In the retrograde approach, no marginal incision lateral nasal walls should be injected via an intercartilagiis made. The lateral crural excision is performed after a retnous approach, staying close to the nasal bones and injectrograde dissection from the intercartilaginous incision.

The needle is then inserted through the vestiapproach is used by many surgeons primarily when nasal bule toward the alar-facial groove to inject the angular tip morphology is normal. An injection is also placed at the base of the coltion, leading to faster healing. The tip is finally injected via the vestibule, anterior to the alar cartilage and into the dome, External Approach with placement confirmed by blanching. Typically, only the external or open approach involves bilateral marginal 10 mL of a local anesthetic is necessary to inject these sites. In addition, the open approach allows for a more precise control of bleeding by electrocautery and a more Endonasal Approach precise correction of deformities. The cartilage-delivery method is nose, which may be associated with more postoperative an example of a closed approach that combines multiple edema. In this approach, intercartilaginous incisions are combined with marginal incisions to allow for Tip-Lobule Complex either externalization or delivery of the lateral crura. This allows for an enhanced visualization of the cartilage, an Alteration and molding of the alar cartilage must be improved ability to manipulate the domes under direct done with precision to avoid visible deformities. In the translope produces an aesthetically pleasing tip-lobule cartilaginous approach, a predetermined amount of lateral complex. It is caused by convex, long, and poorly defined lateral crura that are rounded because of an obtuse angle at the dome. To address this, cephalic trim is used to reduce the curvature of the lateral crura and to create a flat profile. At least 7 mm of remaining crura are needed to ensure sufficient stability and strength. The excision of a triangle of cartilage just lateral to the domes is then used to reduce rounding from the obtuse angle. Staying lateral to the apex of the dome maintains the defining point of an unchanged tip, and the resection of a superior-based triangle allows cephalic rotation and narrowing of the dome. Thick skin does not contract well to an underprojected cartilage frameNasal Valves work and worsens tip definition.

Interlic trims, definition can be improved only by increasing nal valvular incompetence is seen when the angle between alar cartilage projection so the underlying framework the caudal edge of the upper lateral cartilage and the pushes up into the thick overlying skin envelope. Some obstruction can be dynamic, with in these patients, although other techniques that increase underlying weakness of the internal or external nasal projection can also be effective. For example, if the conjoined medial resection and weakening of the lateral crura of the alar crura lose support or are shortened, the tip rotates caudally. The performed by placement of either a batten graft (overlyresection of one lateral crus leads to nasal-tip deviation ing the lateral crus or stabilizing a deficient area) or an toward that side. It is important to note that the shape of a alar strut graft (underlying the lateral crus and straightweakened alar cartilage may also be modified by the conening it) to strengthen the cartilage and prevent coltraction of scar tissue during the healing process or by the lapse. Repair is most commonly by placement of either formation of bossae or knuckles over time. Overresection a lateral graft that spans the crura or a batten graft to must be avoided to maintain stable alar cartilages, which strengthen the cartilage and prevent collapse. Alar retraction is most often caused by poor support A poorly defined and underprojected tip is well of the alar margin resulting from aggressive alar cartiaddressed with rhinoplasty. It may also be caused by lateral crura that used, especially when using the open approach. It may be corrected by placing a graft from septal cartilage, it adds stability to the medial crura, in a pocket along the alar rim (rim graft), by repositionallows for enhanced tip definition and projection, and preing a cephalically oriented lateral crus more caudally, vents tip ptosis.

Reversible causes of hair loss involve an interruption in the natural hair follicle growth cycle. The Androgenetic alopecia in men starts with bitemporal most common types of reversible alopecia include hairline recession followed by thinning of the vertex. Furandrogenetic alopecia (eg, male pattern baldness and ther thinning of the vertex results in a bald patch that female pattern hair loss), alopecia areata, and telogen may enlarge and combine with the progressively receding and anagen effluvium. This eventually results in a narrow rim of is technically reversible because it represents an interhair of the lower parietal and occipital regions. Such female hair loss shows a different pattern common irreversible types of hair loss include those in which a diffuse thinning of the frontal or parietal resulting from scars, trauma, surgery, and burns. Androgenetic Alopecia women typically have normal menses, pregnancies, and general endocrine function. Other reversible causes of hair loss, such as alopecia areata and certain conditions that induce a telogen effluvium, should be ruled out.
