Patient-orientated and radiological outcomes were similarly Clinical outcome poorly uncorrelated in a large study of the long-term results of patients undergoing pos correlates with the terior spondylodesis for spondylolysis and spondylolisthesis [52]. In a study of radiological result 78 patients with adolescent idiopathic scoliosis who had undergone surgery with Harrington instrumentation 20 years previously, the overall long-term clinical outcome (assessed with the Scoliosis Research Society questionnaire) showed no correlation with the radiological outcome [39]. A more comprehensive review of this topic can be found in two recent reviews [41, 58]. Outcome Measures the proportion of positive outcomes after spinal surgery [43] and the factors the patient is the best judge that predict outcome [36, 73] depend to a large extent on the manner in which of the outcome outcome is assessed. There is no single, universally accepted method for assess ing the outcome of spinal surgery. The technical success of the operation also lent itself to evaluation in terms of, for example, the accuracy of screw placement or the degree of fusion/extent of decompression achieved, as monitored by appro priate imaging modalities at follow-up. In an effort to achieve further objectivity, these measures were in the past supplemented with physiological measures such as range of motion or muscle strength [18]. However, in many cases, these mea sures proved to be only weakly associated with outcomes of relevance to the patients and to society. There is now increasing awareness that the outcome should be (at least also) assessed by the patient himself/herself. The previously popular surgical outcome measures have been superseded by Core outcome measures a diverse range of patient-orientated questionnaires that assess factors of impor are pain, function, generic tance to the patient, such as symptoms, disability, quality of life, and ability to well-being, disability, work. However, the emergence of many new instruments in each of these and satisfaction domains, some of which have not been fully validated [92], and the lack of their standardized use, has compromised meaningful comparison among different diagnostic groups, treatment procedures and clinical studies. In recognition of this problem, a standardized set of outcome measures for use with back pain patients was proposed in 1998 by a multinational group of experts [18]. There was general consensus that the most appropriate core outcome measures should 180 Section Basic Science include the following domains: pain, back specific function, generic health status (well-being), work disability, and patient satisfaction [7, 18]. Recent studies have shown that these measures, while related, are not interchangeable as outcome measures [19]. Ithasbeenshownthatitisfeasibletoimplementthisquestionnaireon a prospective basis for all patients being operated on within a busy orthopedic Spine Unit performing approximately 1000 spine operations per year [62]. For more extensive or in-depth clinical trials, it has been suggested that researchers may wish to administer an expanded set of instruments, depending on the par ticular focus of the study. Thiscanbeuseful for retrospective studies in which no patient-orientated baseline data is other wise available or for studies of predictors in which outcome categories are to be Global outcome compared. Recent work has shown that global assessment represents a valid, assessment is desirable unbiased and responsive descriptor of overall effect in randomized controlled trials [35, 57]. Criticisms of global assessment usually include the difficulties in comparing different disease entities, and the dependence of the measures on the baseline characteristics of the groups to be compared [35]; however, both of these can be overcome in observational predictor studies if cases and control groups are well matched. The success of outcome is likely best considered in relation to the a good outcome but also predominant aim of the surgery. For all of these conditions, the ability to regain normal func tion in activities of daily living will also be of importance, although this typically followswithtime,oncethemainsymptomshaveresolved. The cut-off score with the optimal balance between true positive (71%) and false-positive (19%) rates (red line) yields the clinically relevant change score (in this case, a 3-point reduction). A cut-off of 1-point reduction (green line) would be very sensitive (89%) (since most patients with a good out come have at least a 1-point change in score) but would also have a high false-positive rate (55%) (since many poor out come patients may show a 1-point change due to measurement error or for non-specific reasons). A cut-off of 5-points change (orange line) would be less sensitive (46%) (since many patients with a good outcome would not change by as much as 5 points) but more specific (only 7% false-positive rate) (since few patients with a poor outcome would have such a large score change). Thus, sensitivity and specificity can be predictive power calculated for a change score of one point, two points, and so on. This method of diagnostic tests is analogous to evaluating the predictive power of a diagnostic test, in which the to be evaluated instrument (questionnaire) change-score is the diagnostic test and the global outcome (dichotomized as described above) is used to represent the gold stan dard [17]. However, these tend to be less responsive to surgery [7, 38] and often the minimal clinically relevant change borders on the value for the minimal detectable difference. Hence, one must be wary when attempting to make comparisons of different surgical procedures between studies, as some of the variation may simply be attributable to the spe cific outcome measure used. They report the outcome in relation to 2553 patients treated surgically for the most common degenerative lumbar spine dis orders. The greatest proportion of patients were diagnosed with disc herniation the best outcome (50%), followed by central spinal stenosis (28%), lateral spinal stenosis (8%), is achieved for disc segmental pain (8%) and spondylolisthesis (6%). Pain intensity was examined herniations and stenosis prospectively, using visual analogue scales, and pain relief compared with the sit uation before the operation was enquired about using Likert-like responses. For disc herniation patients, 75% reported com plete or almost complete pain relief 4 months postoperatively. This compared with 59% for central spinal stenosis, 52% for lateral spinal stenosis, 66% for seg mental pain and 65% for spondylolisthesis. These values remained relatively sta ble up to 12 months postoperatively, except in the case of segmental pain (which reduced to 45% patients with complete/almost complete pain relief at 12 months) and spondylolisthesis (reduced to 50% at 12 months). Twelve months postopera tively, the ratings of patient satisfaction among the diagnostic categories gener ally followed the same pattern as those for pain relief, with the disc herniation group having the greatest proportion of satisfied patients (75%), and segmental pain the lowest (55%). Predictors of Surgical Outcome Chapter 7 183 the results demonstrate that, for certain indications, there is certainly room for Them orecontentious improvement. This indicates that the problem may lie, at least in part, in the patient selection procedure (see later). Predictors of Outcome of Spinal Surgery the literature reveals a plethora of studies in which predictor factors have been assessed. Recent imaging modalities and operative techniques have advanced so much since the 1980s that negative explorations are now quite rare and the clini cal presentation is more straightforward [12]; hence, studies using diagnostic techniques and/or operative methods that are no longer state-of-the-art may identify predictors that are of little relevance today. The primary aim of many studies is simply to report the outcomes for a given procedure, and the factors associated with a good or bad outcome are considered as incidental or supple mentary information. The latter (often retrospective studies) tend to be less robust in terms of their scientific quality [58]. Other studies specifically set out to examine prospectively the predictors of outcome foragivenspinaldisorderor surgical technique, and it is the results of these studies that are most helpful in identifying the variables that consistently emerge as predictors. Some of the the interplay of the various recent key studies (Table 1) prospectively examined multiple predictor variables, outcome predictors is used valid outcome instruments and employed multivariate analyses. Firstly, predictors can only be found among the variables that are examined in the first place; and, secondly, the failure to evaluate potentially important predictor variables in some studies can lead to overestimation of the importance of the variables that are examined, or to emphasis being placed on different, but closely related variables carrying similar information. One study has shown that preoperative sensory deficit is associated with a good outcome (in terms of back specific function), but the relationship was only evident at 28 months after sur gery and not at the 3 or 12-month follow-ups [90], suggesting it may have been a spuriousfinding.

The implications of potential interactions with antiretroviral drugs have not been determined. Characteristic granulomas may be absent or altered on histologic examination of tissue.

Experience and recommendations continue to evolve, even with older agents such as efavirenz, but particularly with newer drugs. Clinically important interactions with antituberculous agents have not been found with any of the nucleoside or nucleotide analogues (zidovudine, didanosine, stavudine, lamivudine, abacavir, emtricitabine or tenofovir). An increase in dose to 800 mg in those 50 kg was recommended in 2012 by the Food and Drug Administration on the basis of kinetics studies. Rifabutin concentrations may vary when given with lopinavir/ritonavir, and higher than standard 57,58 recommended doses of rifabutin may be required to achieve effective serum concentrations. These reactions may present as fever and clinical and radiologic disease progression at involved sites. Diagnosis is often difficult and requires exclusion of other possible causes of the observed 81 clinical findings, including treatment failure due to drug resistance or development of a different 82 opportunistic infection. If the reaction is severe enough to warrant therapy, corticosteroids such as prednisone at doses in the range of 83 1 mg/kg of body weight have been shown effective in a randomized trial. Corticosteroid therapy (prednisone 1 mg/kg daily) may be considered if the reaction is severe.

Some species are associated with clinical diseases as well as a spectrum of clinical findings, whereas other species are rarely, if ever, associated with disease. Historically, the mycobacteriology laboratory served to isolate and speciate Mycobacterium tuberculosis complex organisms. This capacity to isolate known mycobacterial pathogens gradually 2 enabled the laboratory to isolate other mycobacteria, of unknown or lesser pathogenicity. In other patients, there may be a spectrum of findings ranging from minimal and nonprogressive symptoms to more extensive lung disease with chest imaging abnormalities. A bronchoscopic isolate should be corroborated with sputum results if both samples are available. A single bronchoscopic isolate in the presence of repeatedly negative sputum samples should be interpreted cautiously. Where there is doubt about whether to treat or defer, one should obtain more specimens and consider further investigations before formulating a treatment plan and defining the therapeutic goal(s). Recommendations in this chapter are focused largely on therapy, and are 3 summarized and rated in Table 2. Recommended treatment of nontuberculous mycobacterial disease * Organism Drugs Duration M.

Thoracic Curves A single thoracic curve may be treated by anterior or posterior fusion, the latter being the classic approach. Using pedicle screws instead of hooks offers a better curve correc Idiopathic Scoliosis Chapter 23 649 a c Figure 9. Pedicle screws allow for a the use of pedicle screws allows for a better rotational and coronal correction better scoliosis correction [109]. In the hands of an experienced surgeon, neurological problems were not found to be higher with the use of pedicle screws [101]. The advantage of an ante rior correction is the shorter fusion length and better derotation (Fig. The anterior approach has a cosmetic advantage if the operation is performed by means of a mini-thoracotomy or thoracoscopy leaving only small scars. Although spontaneous lumbar curve correction occurs after both selective pos terior and anterior thoracic fusion, the correction was found to be better in the latter approach [111]. When planning surgery for double-thoracic curves,preop In double thoracic curves erative shoulder balance (T1-tilt) and size (Cobb angle) and rigidity of the proxi attention must be paid to mal thoracic curve must be considered to achieve a good outcome [108]. If the shoulder balance, curve size shoulder is elevated on the convex side of the major thoracic curve. These curves benefit most from a short anterior scoliosis cor rection (Case Introduction), preserving more mobile motion segments com 650 Section Spinal Deformities and Malformations pared to posterior fusion [60, 142]. Double Major Curves these curve patterns with a thoracic and a thoracolumbar or lumbar structural curve are usually operated on from posteriorly indicating that a big part of the spine has to be fused. Attempts to fuse the lumbar curve anteriorly and only the thoracic curve posteriorly have recently been suggested. It was reported that an anterior release with instrumented fusion of the lumbar curve was superior to an anterior release followed by posterior instrumented fusion [236]. Only prelimi nary data is available on the short selective anterior fusion of both the thoracic Motion segment preser and the lumbar curve with the potential advantage of preserving motion seg vation is an important goal ments in double major curves [141]. Adult Idiopathic Scoliosis the general state of health, age and bone quality play important roles in the sur gical decision-making. Morbidity for surgery is lower in younger patients (<40 years) and the chance of a better outcome will also be higher than in older Surgical treatment patients (>40 years) [17, 46, 210]. Surgical decision-making in adult idiopathic is strongly influenced scoliosis strongly depends on the underlying causes of pain, which have to be by the pain sources explored thoroughly. With predominant irradiating pain or claudication without relevant back pain, selective spinal decompression may be performed as a stand alone procedure [1]. In younger patients a partial correction of the deformity may already lead to a sufficient decompression without a formal decompression being performed (Case Study 2). If additional segmental instability, extensive degenerative changes and progressive deformity lead to back pain, posterior and/or anterior fusion and stabilization with/without decompression and cor rection may be required [194]. To achieve a balanced spine and prevent a postop erative collapse of the adjacent segment, the fusion usually has to extend beyond the major curve. Stopping the fusion of a lumbar curve below the thoracolumbar junction usually bears a high risk of sagittal decompensation of the spine crani ally [83]. It is still controversial whether or not the lumbosacral junction should be included in the fusion [17, 19, 45, 90]. If unfused, the L5/S1 segment has to take all the movements and loads of the fused lumbar spine [107, 194]. Furthermore, a fusion to the sacrum leads to higher stress for the sacroiliac and hip joints. Non union rates of up to 30% are reported if the fusion is not done circumferentially [19, 59]. The goal is to achieve It has to be borne in mind that the spine may be in a fragile balance before sur a balanced spine without gery and that a decompression and/or a partial fusion may lead to a deterioration pain and normal neurology of this balance leading to progressive deformity and disability. If spinal balance is preserved, fusion in situ will often be the method of choice as an adjunct to decompression [1]. An imbalanced spine with secondary degenerative changes requires extensive release of the posterior structures and in some cases multiple spinal osteotomies (see Chapter 26). Idiopathic Scoliosis Chapter 23 651 c a Case Study 2 A 25-year-old female with a known but untreated scoliosis for many years presented because of incapacitating lum bar back and leg pain with inability to continue with full time work. Standard radiographs demonstrated a major thoracolumbar curve of 56 degrees and a minor thoracic curve of 42 degrees (a, b). The radiographs revealed a bal anced spine with excellent curve correction (e, f). Neurological injury can result from either direct contusion or an ischemic insult. Complications in scoliosis surgery spinal cord injury is rare Complication Incidence References spinal cord injury 0. Therefore, a reduction of the cor rection and restoration of a sufficient perfusion should be achieved if neurologi cal injury is noticed intraoperatively. Ligation of anterior segmental arteries has also been suggested to increase the likelihood of ischemia of the cord [21]. Mal nourished and immunocompromised patients are at substantially higher risk for infections [104]. If an early wound infection is diagnosed, wound revision and antibiotic treatment after isolation of the germ is indicated. Titanium implants can be left in place to avoid loss of correction and non-union [212]. Delayed wound infections Delayed wound infections occur 20 weeks or longer after the initial interven are caused by low-virulent tion. If the diag germs nosis is confirmed, surgical intervention is indicated removing all implants. If the fusion is solid, usually no further measures are necessary besides implant removal. Non-union may be associated with hardware loosening, dislodgement or breakage requiring revision surgery.

Today, pedicle screws are frequently used as liosis remains a therapeutic challenge because of they allow a better correction and shorter fusion the adverse effects of multisegmental fusion in a length than systems only using hooks and wires.
