BACKGROUND & AIMS: :Results from pharmacogenetic investigations of methylphenidate (MPH) response in patients with ADHD are still inconsistent, especially among adults. This study investigates the role of genetic variants (SLC6A4, HTR1B, TPH2, DBH, DRD4, COMT, and SNAP25) in the response to MPH in a sample of 164 adults. Genes were chosen owing to previous evidence for an influence in ADHD susceptibility. No significant differences in allele or genotype frequencies between MPH responders and nonresponders were detected. In conclusion, our findings do not support an effect of these genes in the pharmacogenetics of MPH among adults with ADHD.

背景与目标： : 多动症患者中哌醋甲酯 (MPH) 反应的药物遗传学研究结果仍然不一致，尤其是在成年人中。这项研究调查了164名成年人样本中遗传变异 (SLC6A4，HTR1B，TPH2，DBH，DRD4，COMT和SNAP25) 对MPH反应的作用。由于先前的证据对ADHD易感性有影响，因此选择了基因。在MPH应答者和非应答者之间未检测到等位基因或基因型频率的显着差异。总之，我们的发现不支持这些基因在ADHD成人中MPH的药物遗传学中的作用。

BACKGROUND & AIMS: BACKGROUND:The process and preparation of moving from child to adult services (transition) is a challenging period of time for young people and represents significant changes in care and support systems. The proliferation of mobile phone applications for health purposes suggests that it is an area for further investigation. OBJECTIVE:The review explores the potential to use mobile phone technology to help support young liver transplant recipients moving to adult services. It represents the first review conducted in this specialism and considers a new model of support for young liver patients. METHODS:A systematic rapid review of the published peer-reviewed literature. RESULTS:Two searches were conducted: Search 1: the use of technology to support transition to adult services (6 studies) and Search 2: how best to support liver transplant recipients during transition (6 studies). DISCUSSION:Research shows that to achieve positive transition young people need information about their condition and transition. The process needs to be guided by transition readiness, rather than the young persons' age. Although parents and support networks should be in place and are valued, transition should build upon self-management and independence. Results suggest that there appears to be scope to use mobile phone technology to support transition. This is the first time a review has explored the types of issues or concerns facing liver transplant patients and how these can be addressed through mobile phone technology.

BACKGROUND & AIMS: :Normal adult zebrafish can completely regenerate lost myocardium following partial amputation of the ventricle apex. We report that 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) significantly impairs this regeneration. Adult male zebrafish were injected with vehicle (control) or TCDD (70ng/g, ip) 1 day prior to partial amputation of the ventricle apex. Gross observation and histological analysis of the amputated heart at 21 days postamputation revealed that TCDD-exposed fish had not progressed beyond the initial clot formation stage, whereas the vehicle control fish showed substantial recovery and almost complete resolution of the formed clot. In contrast, hearts that were not surgically wounded showed no signs of TCDD toxicity. Striking features in the TCDD-exposed hearts were the absence of the normal sheath of new tissue enveloping the wound and the absence of intense cell proliferation at the site of the wound. In addition, the patterns of collagen deposition at the wound site were different between the TCDD and vehicle groups. Because the receptor for TCDD is the aryl hydrocarbon receptor ligand-activated transcriptional regulator, we examined the effects of TCDD exposure on gene expression in the ventricle using DNA microarrays. Samples were collected just prior to amputation and at 6h and 7 days postamputation. TCDD-pretreated hearts had dysregulated expression of genes involved in heart function, tissue regeneration, cell growth, and extracellular matrix. Because embryonic, but not adult, hearts are major targets for TCDD-induced cardiotoxicity, we speculate that the need for embryonic-like cells in regeneration is connected with the effects of TCDD in inhibiting the response to wounding.

背景与目标： : 正常成年斑马鱼可以在部分截肢心室尖后完全再生丢失的心肌。我们报告2,3，7,8-四氯二苯并-对-二恶英 (TCDD) 显著损害这种再生。成年雄性斑马鱼在脑室尖部分截肢前1天注射赋形剂 (对照) 或TCDD (70ng/g，ip)。截肢后21天对截肢心脏的总体观察和组织学分析表明，暴露于TCDD的鱼没有进展超过最初的凝块形成阶段，而媒介物对照鱼则显示出实质性的恢复和形成的凝块的几乎完全消退。相反，未手术受伤的心脏没有TCDD毒性的迹象。暴露于TCDD的心脏的显着特征是没有包裹伤口的新组织的正常鞘，并且在伤口部位没有强烈的细胞增殖。此外，TCDD组和媒介物组在伤口部位的胶原沉积模式也不同。由于TCDD的受体是芳基烃受体配体激活的转录调节因子，因此我们使用DNA微阵列检查了TCDD暴露对心室中基因表达的影响。在截肢前以及截肢后6小时和7天收集样本。TCDD预处理的心脏与心脏功能，组织再生，细胞生长和细胞外基质有关的基因表达异常。由于胚胎而不是成年心脏是TCDD诱导的心脏毒性的主要靶标，因此我们推测再生中对胚胎样细胞的需求与TCDD抑制对创伤的反应有关。

BACKGROUND & AIMS: :Septic arthritis of the hip can be caused via a hematogenous route, by penetration of periarticular infections, open hip trauma, injections or operations. Ultrasound, hip puncture and elevation of inflammatory parameters lead to the diagnosis. Differentiation of septic arthritis from gout and chondrocalcinosis may be difficult. Nevertheless, early revision of the hip has to be performed to avoid joint destruction. Open revision is the therapy of choice in the majority of cases.

背景与目标： : 败血症性关节炎的髋部可通过血行途径，通过穿透关节周围感染，开放性髋部创伤，注射或手术引起。超声，髋部穿刺和炎症参数升高导致诊断。化脓性关节炎与痛风和软骨钙质病的鉴别可能很困难。尽管如此，必须对髋关节进行早期修复，以避免关节破坏。在大多数情况下，开放修订是首选疗法。

BACKGROUND & AIMS: :This case report describes the orthodontic treatment of an 18-year-old woman with a skeletal Class III malocclusion and a midline deviation. The treatment plan consisted of distalizing the mandibular dentition asymmetrically and producing space for retraction of the mandibular anterior teeth. Short Class III elastics, an open-coil spring, and the mulitloop edgewise archwire technique were used, combining the entire maxillary dentition as integrated anchorage. The active treatment period was 26 months. Normal overbite and overjet were obtained, and facial balance was improved.

背景与目标： : 此病例报告描述了一名18岁女性的正畸治疗，该女性患有骨骼III类错牙合且中线偏离。治疗计划包括不对称地使下颌牙列远端，并为下颌前牙的缩回提供空间。使用了III类短弹性，开式螺旋弹簧和多环边沿弓丝技术，将整个上颌牙列结合为整体锚固。积极治疗期为26个月。获得了正常的咬合和过度喷射，并改善了面部平衡。

BACKGROUND & AIMS: OBJECTIVE:This pilot study was a comparison of dimensional models assessing personality traits and personality pathology in a clinical sample of adults diagnosed with ADHD and adults diagnosed with borderline personality disorder (BPD), and a nonclinical control sample of healthy adults. METHOD:Personality traits were assessed using the NEO-Personality Inventory-Revised (NEO-PI-R) and dimensional personality pathology with the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ). RESULTS:Adults with ADHD and BPD produced higher Emotional Dysregulation/Neuroticism and Dissocial Behavior scores than controls. For the Extraversion/Inhibitedness scale, adults with BPD produced significantly lower scores than adults with ADHD and controls. On the Conscientiousness/Compulsivity domains, Conscientiousness scores were lower for both disorders, whereas low Compulsivity values were specific to adult ADHD. CONCLUSION:Our results suggest that patients with adult ADHD and BPD have distinguishable profiles of personality traits and personality pathology.

BACKGROUND & AIMS: Members of the Notch gene family are thought to be involved in the regulation of cell fate decisions in a variety of embryonic tissues, particularly in the developing central nervous system (CNS) in Drosophila and vertebrates. In goldfish the CNS continues to develop and add neurons well into adulthood and has the capacity to regenerate new neurons. Using probes derived from Xenopus Notch to screen an adult goldfish retinal cDNA library, followed by 5' RACE, we isolated a partial cDNA for a goldfish Notch homologue, G-Notch. Sequence alignment supported assignment of G-Notch to the Notch-3 class. Northern blot analysis revealed a single transcript of > 8 kb, and RNase protection assays indicated that G-Notch is expressed in eye and brain but not muscle of adult goldfish. The spatiotemporal pattern of expression of G-Notch was defined from early embryonic stages to adulthood by in situ hybridization. Expression in the embryonic CNS was localized to neurogenic regions and was downregulated in differentiated cell populations. In adult goldfish, expression persisted in and adjacent to the germinal zones in the retina and the brain. Weak expression was seen in scattered cells in the inner nuclear layer of the retina, which might include neurogenic stem cells. Following retinal lesions (puncture wounds or laser lesions restricted to photoreceptors in the outer nuclear layer), G-Notch was upregulated in proliferating cell populations throughout the retina, in association with a generalized mitogenic response. In the region of the laser lesion, where earlier studies have demonstrated that photoreceptors are regenerating at 1-3 weeks following the lesion, G-Notch expressing cells were abundant in the outer nuclear layer. These observations suggest that retinal regeneration involves the re-expression of an important developmental signaling molecule in neuroepithelial cells resident in the differentiated retina.

背景与目标： Notch基因家族的成员被认为参与了多种胚胎组织中细胞命运决定的调节，尤其是果蝇和脊椎动物发育中的中枢神经系统 (CNS)。在金鱼中，中枢神经系统继续发育并增加神经元到成年，并具有再生新神经元的能力。使用源自非洲爪蟾Notch的探针筛选成年金鱼视网膜cDNA文库，然后进行5' 竞赛，我们分离了金鱼Notch同源物G-Notch的部分cDNA。序列比对支持将G-Notch分配给Notch-3类。Northern印迹分析显示单个转录本> 8 kb，RNase保护试验表明G-Notch在成年金鱼的眼睛和大脑中表达，但在肌肉中不表达。通过原位杂交定义了从胚胎早期到成年的G-Notch表达的时空模式。胚胎CNS中的表达定位于神经源性区域，并在分化的细胞群体中下调。在成年金鱼中，表达持续存在于视网膜和大脑的生发区并与其相邻。在视网膜内核层的分散细胞中观察到弱表达，其中可能包括神经源性干细胞。视网膜病变 (穿刺伤口或激光损伤仅限于外核层的光感受器) 后，G-Notch在整个视网膜的增殖细胞群中被上调，并伴有普遍的促有丝分裂反应。在激光病变区域，较早的研究表明，光感受器在病变后1-3周再生，在外核层中表达G-Notch的细胞丰富。这些观察结果表明，视网膜再生涉及驻留在分化视网膜中的神经上皮细胞中重要的发育信号分子的重新表达。

BACKGROUND & AIMS: :Mesial temporal lobe epilepsy (mTLE) is a neurological condition characterized by the occurrence of spontaneous recurrent seizures originating from mesial structures involving the hippocampus within the temporal lobe. This condition is often associated with pathological features in the hippocampus such as neuronal cell loss, widening of the granule cell layer, astrogliosis and mossy fibre spouting. At present, the mechanisms underlying these pathological features are unclear. However, recent advances in adult neurogenesis studies in mTLE animals and patients suggest that newly generated neurons may contribute to the pathogenesis of ongoing epileptogenesis. This article will review the recent animal and human studies on adult neurogenesis in mTLE and discuss how these results suggests that adult endogenous neurogenesis may not always be reparative in the mTLE and may be targeted in new therapeutic strategies for mTLE.

背景与目标： : 颞叶内侧癫痫 (mTLE) 是一种神经系统疾病，其特征是发生自发性复发性癫痫发作，起源于颞叶内海马的内侧结构。这种情况通常与海马的病理特征有关，例如神经元细胞丢失，颗粒细胞层变宽，星形胶质细胞增生和苔藓状纤维喷出。目前，这些病理特征的机制尚不清楚。然而，在mTLE动物和患者中进行的成人神经发生研究的最新进展表明，新生的神经元可能有助于正在进行的癫痫发生的发病机理。本文将回顾最近有关mTLE中成人神经发生的动物和人类研究，并讨论这些结果如何表明成人内源性神经发生可能并不总是在mTLE中修复，并且可能在mTLE的新治疗策略中靶向。

BACKGROUND & AIMS: PURPOSE:To determine the toxicities, pharmacokinetics, and maximally tolerated doses of oxaliplatin in patients with hepatic impairment and to develop formal guidelines for oxaliplatin dosing in this patient population. EXPERIMENTAL DESIGN:Sixty adult cancer patients with variable hepatic function received i.v. oxaliplatin ranging from 60 to 130 mg/m(2) every 3 weeks. Patients were stratified by levels of total bilirubin, aspartate aminotransferase (AST), and alkaline phosphatase (AP) into five cohorts based on the degree of hepatic dysfunction: control group A [bilirubin, AST, and AP < or = upper limit of normal (ULN)], mild dysfunction group B (bilirubin < or = ULN, ULN < AST < or = 2.5 x ULN, or ULN < AP < or = 5 x ULN), moderate dysfunction group C (ULN < bilirubin < or = 3.0 mg/dL, AST > 2.5 x ULN, or AP > 5 x ULN), severe dysfunction group D (bilirubin > 3.0 mg/dL, any AST, and any AP), and liver transplantation group E (any bilirubin, any AST, and any AP). Doses were escalated in cohorts of three patients, and urine and plasma ultrafiltrates were assayed for platinum concentrations. RESULTS:Dose escalation of single-agent oxaliplatin to 130 mg/m(2) was well tolerated in all cohorts. Platinum clearance did not correlate with any liver function test. Two of 56 assessable patients with a diagnosis of laryngeal carcinoma and cervical adenocarcinoma experienced partial responses lasting 3 and 5.5 months. CONCLUSIONS:Oxaliplatin at 130 mg/m(2) every 3 weeks was well tolerated in all patients with impaired liver function. Dose reductions of single-agent oxaliplatin are not indicated in patients with hepatic dysfunction.

BACKGROUND & AIMS: :The efficacy of cognitive behavioral treatments (CBT) for anxiety in adults has been supported by multiple meta-analyses. However, most have focused on only 1 diagnosis, thereby disallowing diagnostic comparisons. This study examined the efficacy of CBT across the anxiety disorders. One hundred eight trials of CBT for an anxiety disorder met study criteria. Cognitive therapy and exposure therapy alone, in combination, or combined with relaxation training, were efficacious across the anxiety disorders, with no differential efficacy for any treatment components for any specific diagnoses. However, when comparing across diagnoses, outcomes for generalized anxiety disorder and posttraumatic stress disorder were superior to those for social anxiety disorder, but no other differences emerged. CBT effects were superior to those for no-treatment and expectancy control treatments, although tentative evidence suggested equal effects of CBT when compared with relaxation-only treatments.

背景与目标： : 认知行为治疗 (CBT) 对成年人焦虑的功效已得到多项荟萃分析的支持。然而，大多数只关注1个诊断，因此不允许进行诊断比较。这项研究检查了CBT在焦虑症中的功效。针对焦虑症的CBT试验达到了研究标准。单独使用认知疗法和暴露疗法，或与放松训练相结合，在焦虑症中是有效的，对于任何特定诊断的任何治疗成分都没有不同的功效。然而，当比较各种诊断时，广泛焦虑症和创伤后应激障碍的结果优于社交焦虑症，但没有其他差异。CBT效果优于无治疗和预期对照治疗，尽管初步证据表明CBT与仅松弛治疗相比具有相同的效果。

BACKGROUND & AIMS: :Tuberculous meningitis (TBM) is the most common form of central nervous system tuberculosis with a very poor prognosis. We aimed at assessing risk factors related to the prognosis of patients with TBM.Forty-five inpatients with TBM in our institution from January 2013 to December 2015 were enrolled retrospectively. The good or poor prognosis in the patients was defined, based on Glasgow Outcome Scale System at discharge. Patients with a GOS score less than 5 were defined as "poor prognosis." Univariate and multivariate logistic regression analyses were performed to assess the predictors for TBM outcome.Among 45 TBM patients, 35 (77.8%) and 10 (22.2%) were in good, poor prognoses, respectively. Old age, disturbance of consciousness, moderate to severe electroencephalogram abnormality, hydrocephalus, remarkable increase of protein (≥ 236 mg/dL) and white blood cell counts (≥ 243 /μL) in cerebral spinal fluid were associated with poor prognosis. Multivariate analysis indicated that old age (odds ratio (OR) = 18.395, P = .036) and hydrocephalus (OR = 32.995, P = .049) were independent factors for a poor outcome of TBM.In conclusion, old age and hydrocephalus are the predictors for poor prognosis of TBM. Patients with these risk factors should be treated promptly with a special care paid to improve their outcomes.

背景与目标： 结核性脑膜炎 (TBM) 是中枢神经系统结核病的最常见形式，预后很差。我们旨在评估与TBM患者预后相关的危险因素。我们机构从2013年1月到2015年12月的45例TBM住院患者被回顾性纳入。根据出院时格拉斯哥结局量表系统，确定了患者的良好或不良预后。GOS评分小于5的患者被定义为 “不良预后”。进行单因素和多因素logistic回归分析以评估TBM结果的预测因素。在45例TBM患者中，分别有35例 (77.8% 例) 和10例 (22.2% 例) 预后良好。年龄大、意识障碍、中重度脑电图异常、脑积水、脑脊液中蛋白质 (≥ 236  mg/dL) 和白细胞计数 (≥ 243  /μ l) 均与预后不良相关。多因素分析显示，高龄 (优势比 (OR)  =   18.395，p   =  .036) 和脑积水 (OR   =   32.995，p   =  .049) 是TBM预后不良的独立因素。老年和脑积水是TBM预后不良的预测因素。具有这些危险因素的患者应及时接受特殊护理治疗，以改善其预后。

BACKGROUND & AIMS: AIMS:To characterize the population pharmacokinetics of tipifarnib. METHODS:A total of 1083 subjects treated orally with a solution, capsule or tablet formulations of tipifarnib, given as a single dose or as multiple twice-daily doses (range 25-1300 mg) were combined with data from 1, 2 and 24 h intravenous infusions. A total of 3445 concentrations in the index data set were fitted by an open three-compartment linear disposition model with sequential zero-order input into the depot compartment, followed by a first-order absorption process, and lag time, using NONMEM V. The effect of patient covariates on tipifarnib pharmacokinetics was explored. The model was evaluated using goodness of fit plots and relative error measurements for 3894 concentrations in the test data set. Computer simulations were undertaken to evaluate the effect of covariates on tipifarnib pharmacokinetics. RESULTS:Tipifarnib oral bioavailability (26.7%) did not differ between the formulations. The absorption rate from the solution was faster than from the solid forms. Whereas the absorption rate and systemic clearance were more rapid in healthy subjects, the extent of absorption and the steady-state volume of distribution were comparable in cancer patients and healthy subjects. Systemic clearance in cancer patients (21.9 l h-1) exhibited a statistically significant relationship with total bilirubin. The typical volume of the central compartment in cancer patients (54.6 l 70 kg-1) was directly proportional to body weight. The clinical relevance of these covariates in cancer patients is questionable as there was a substantial overlap in simulated concentration-time profiles across a wide range of covariate values. CONCLUSIONS:A population PK approach has been used to integrate data gathered during clinical development and to characterize the pharmacokinetics of tipifarnib. Individualization of dose based on body weight or total bilirubin concentration in adult cancer patients is not warranted.

BACKGROUND & AIMS: :Customarily, it is taught that strabismus acquired in childhood results in suppression of the diplopic image, whereas strabismus acquired in adulthood causes diplopia or conscious image ignoring, but not true cortical suppression. The pattern visual evoked potential (PVEP) was recorded from strabismic patients, three with childhood onset, two adult onset with diplopia, and three with longstanding adult onset strabismus "ignored" diplopia. Patients with childhood onset and adult onset "ignored" diplopia similarly showed essentially no response under haploscopic stimulation, whereas patients with diplopia and normal control subjects showed a 50% decrease (rivalry). These results suggest that adults with acquired strabismus who "ignore" the diplopic image actually have a suppressed cortical visual activity, as evidenced by the pattern visual evoked potential.

背景与目标： : 习惯上，被告知儿童时期获得的斜视会导致复视图像的抑制，而成年后获得的斜视会导致复视或意识图像的忽略，但不是真正的皮质抑制。斜视患者记录了模式视觉诱发电位 (PVEP)，其中三例为儿童期发作，两例为复视成人发作，三名为长期发作的斜视 “被忽略” 复视。类似地，儿童发作和成人发作 “被忽略” 的复视患者在单倍镜刺激下基本上没有反应，而复视患者和正常对照受试者则表现出50% 的下降 (竞争)。这些结果表明，患有后天性斜视的成年人 “忽略” 了双重图像，实际上皮质视觉活动受到抑制，这由模式视觉诱发电位证明。

BACKGROUND & AIMS: :Post-remission therapy in acute myeloid leukemia (AML) remains problematic. It has been demonstrated that younger patients can maintain longer complete remissions (CR) with aggressive post-remission therapies after induction treatment: allogeneic (allo), autologous (auto) stem cell transplantation (SCT), or intensive chemotherapy (ICC). The purpose of our study was to identify the most important randomized and controlled studies comparing these three therapeutic options, in order to draw conclusions and possible suggestions for post-remission therapy of AML, according to the evidence based medicine (EBM) rules. We performed an exhaustive analysis of the literature, searching either in electronic databases or among the references of the identified articles (hand searching). We searched the MEDLINE computer database for reports from 1985 through January 2005 and selected for analysis the clinical trials conducted over adults affected by newly diagnosed AML aged less than 65 years. The study design had to satisfy strict methodological criteria and must consider global mortality and/or disease free survival as primary outcomes. Overall we found 7750 papers; by using the limits "clinical trial" as publication type, "all adults 19+ years", we were able to select 344 papers. Among these, a further selection was made, based on two main clinical queries: 1) is auto-SCT superior to ICC/no other therapy in improving DFS and/or OS in adult AML patients in first CR? 2) is allo-SCT superior to auto-SCT/other therapeutic options in improving DFS and/or OS in adult AML patients in first CR? Concerning the first query, a possible advantage of auto-SCT over ICC was not clearly supported by data from clinical trials; there is no evidence that auto-SCT is superior in terms of OS to chemotherapy. Nevertheless, the reported TRM has been significantly reduced within the past years. Thus, the percentage of patients suitable for auto-SCT in CR has increased. Moreover, the scarce data concerning the comparison between auto-SCT and chemotherapy in different subsets of patients are unable to suggest a differentiated approach in patients with high-risk, standard-risk or low-risk AML. Data from the literature show that patients with unfavorable risk disease are more often addressed to allo-SCT and patients with low-risk disease receive more often intensive consolidation chemotherapy. Concerning the second query, interpretation of data from the main prospective studies about the role of allo-SCT in previously untreated AML is not easy. The first problem is the lack of real randomized clinical trials; in fact, according to the reported studies, AML patients generally receive allo-SCT on the basis of donor availability (the so called "genetic randomization"). The second problem is the frequent absence of intention to treat analysis. Despite methodological limitations, it was possible to compare allo-SCT with auto-SCT on a donor versus no-donor analysis and within risk groups. No overall benefit of allo-grafting on survival was demonstrated by any trial. In conclusion, the EBM approach highlighted the limitations observed in the published studies concerning consolidation therapy in AML; some suggestions, emerging from non-randomized, as well as randomized studies, are adequate, but not conclusive. This point, coupled with the intrinsic complexity to study AML biological heterogeneity, is probably a major obstacle to draw conclusive evidences for consolidation therapy in AML. These observations should plan to address new randomized studies on AML therapy; however, due to the emergence of genetic subgroups and new drugs targeting specific abnormalities, these trials should probably be designed directly focusing on the single entities. In this way, the cure of AML could eventually become the cure of each specific AML subset with its peculiar biological, molecular and prognostic features.

背景与目标： : 急性髓系白血病 (AML) 的缓解后治疗仍然存在问题。已证明，年轻患者在诱导治疗后可以通过积极的缓解后疗法维持更长的完全缓解 (CR): 异体 (allo)，自体 (auto) 干细胞移植 (SCT) 或强化化疗 (ICC)。我们研究的目的是确定比较这三种治疗方案的最重要的随机和对照研究，以便根据循证医学 (EBM) 规则得出结论和可能的AML缓解后治疗建议。我们对文献进行了详尽的分析，在电子数据库中或在已识别文章的参考文献中进行搜索 (手工搜索)。我们在MEDLINE计算机数据库中搜索了通过2005年1月1985年的报告，并选择了针对年龄小于65岁的新诊断AML的成年人进行的临床试验进行分析。研究设计必须满足严格的方法学标准，并且必须将全球死亡率和/或无病生存率作为主要结果。总的来说，我们发现了7750篇论文; 通过使用限制 “临床试验” 作为出版类型，“所有成人19岁”，我们能够选择344篇论文。其中，基于两个主要的临床问题进行了进一步的选择: 1) 在改善首次CR的成年AML患者的DFS和/或OS方面，auto-SCT是否优于ICC/no其他疗法？2) 在改善首次CR的成年AML患者的DFS和/或OS方面，allo-SCT是否优于auto-SCT/其他治疗选择？关于第一个查询，临床试验数据并未明确支持auto-SCT优于ICC的可能优势; 没有证据表明auto-SCT在OS方面优于化疗。然而，在过去几年中，报告的TRM已大大减少。因此，CR中适合auto-SCT的患者百分比增加了。此外，关于不同患者亚组中auto-SCT和化疗之间比较的稀缺数据无法提示高风险，标准风险或低风险AML患者的差异化方法。来自文献的数据表明，患有不利风险疾病的患者更常接受allo-SCT治疗，而低风险疾病的患者更常接受强化强化化疗。关于第二个查询，对来自主要前瞻性研究的有关allo-SCT在先前未经治疗的AML中的作用的数据的解释并不容易。第一个问题是缺乏真正的随机临床试验; 实际上，根据报道的研究，AML患者通常根据供体的可用性接受allo-SCT (所谓的 “遗传随机化”)。第二个问题是经常缺乏治疗分析的意图。尽管方法上有局限性，但可以在供体分析与无供体分析以及风险组中比较allo-SCT与auto-SCT。任何试验均未证明同种异体移植对生存的总体益处。总之，EBM方法强调了在已发表的关于AML巩固治疗的研究中观察到的局限性; 从非随机和随机研究中提出的一些建议是足够的，但不是结论性的。这一点，加上研究AML生物异质性的内在复杂性，可能是为AML巩固治疗得出确凿证据的主要障碍。这些观察结果应计划解决有关AML治疗的新的随机研究; 但是，由于遗传亚组的出现和针对特定异常的新药的出现，这些试验可能应直接针对单个实体进行设计。这样，AML的治疗最终可以成为每个特定AML子集的治疗方法，具有其独特的生物学，分子和预后特征。

BACKGROUND & AIMS: OBJECTIVE:To determine the prevalence and distribution of dilaceration in all tooth groups by using radiographs. STUDY DESIGN:The sample included 953 periapical intraoral radiographs and 488 panoramic radiographs from different caucasian patients. The ages of the patients ranged from 18-65 years. Dilaceration of the root was detected by measuring the degree of deviation from the long axis (deviation ł 90 degrees), and evaluating the "bull's eye" appearance. The prevalence of root dilaceration for each tooth-type was expressed in percentages. RESULTS:The teeth showing the highest prevalence of root dilaceration were mandibular third molars (24.1%), maxillary first molars (15.3%), second molars (11.4%) and third molars (8.1%). In the mandible, dilacerations were less common than in the maxilla. CONCLUSIONS:In the adult population examined in Croatia, dilaceration was most frequently found to affect posterior teeth.
