The present study was undertaken in sportsmen of those groups of sports activities where weight training exercises constitute a major part of the training. Two groups consisting of 25 weight-lifters and 25 track and field athletes were studied to find out the effect of sports activities and lifting weights on the spine. 84% weight-lifters and 72% track and field athletes suffered from varying abnormalities. Incidence of backache in 25 weight-lifters was 40% and in 25 track and field athletes 48%. Radiological changes were more common in weight-lifters (84%) than in athletes (72%). Reduction in lumbar lordosis was found in three cases (12%) in both the groups. Obtuse angle deformity of vertebral margins was found in 11 cases (44%) amongst weight-lifters and six cases (24%) amongst athletes. Osteophytic formation was found in six cases (24%) in weight-lifters and four cases (16%) in athletes. Schmorl's node were noticed in five cases (20%) amongst weight-lifters and seven cases (28%) amongst athletes. The incidences of spondylosis and Schmorl's node were found only in those cases who had been doing weight training exercises for more than four years. [ABSTRACT FROM PUBLISHER]

Until date conventional radiographs and computed tomography are the preferred diagnostic modalities to monitor the distraction osteogenesis regenerate. But these techniques do not detect the ongoing osteogenic process; moreover they obligate the patient to serial radiation exposure. In addition, anatomic overlap and metal artifacts obscure the virtual findings. In contrast, ultrasound is a noninvasive, efficient and an inexpensive way to evaluate bone healing. This study was conducted to test the efficacy of ultrasound in evaluating bone healing at the mandibular distraction site. Twenty patients underwent mandibular distraction. The wounds were assessed with an orthopantomograph and an ultrasound at the end of latency, mid distraction, end of distraction and post distraction periods i.e. 6 weeks, 8 weeks and 4months. Estimates of bone formation, using a semiquantitative radiological, ultrasonographic and intraoperative surgical bone fill scores were made. The correlation between intraoperative and ultrasonographic bone fill scores was statistically significant at 0.602, a total of 26 of the 31 sites correlated. Corresponding correlation between intraoperative and radiographic bone fill scores was 0.332, and only 13 of the 31 sites correlated. The results indicate that ultrasound is potentially an accurate noninvasive technique that is most useful in assessing the mandibular distraction regenerate.

Introduction: Depression is one of the under-recognized health problems in adolescents. Emotional instability resulted from childhood to adulthood transition makes adolescents vulnerable to depression., Aims: The aim of the study was to explore the prevalence of depression and its associated sociodemographic factors among school-going adolescents., Materials and Methods: This cross-sectional study was undertaken from January 2016 to June 2016 in adolescents studying in 9-12 th standard from forty schools located in an urban area of Patna, Bihar. The self-administered questionnaire of Beck's Depression Inventory II was utilized to assess the prevalence of depression. Statistical analysis was done with Pearson's Chi-square test using SPSS software version 21.0., Results: Among the 1412 selected students, the prevalence of depression was found to be 49.2%, wherein the prevalence of severe depression was 7.7%. The overall prevalence of depression was significantly ( P < 0.001) higher among girls (55.1%) than boys (45.8%). The prevalence of depression was found to be higher among students belonging to minorities (Buddhism, Jainism, etc.) (63.3%, P < 0.001). Elder students were found to be more depressed than younger students. Depression was found to be statistically significantly associated with gender and religion ( P < 0.005). Guilty feeling (69.48%) was one of the most prominent clinical factors associated with depression followed by pessimism (58.14%), sadness (56.52%), and past failure (55.81%)., Conclusions: Mental health is one of the most neglected aspects of our society. There is a need to increase awareness about depression among teachers and parents to identify and help depressed adolescents in the school., Competing Interests: There are no conflicts of interest.

Unlabelled: Acute liver failure remains a critical clinical condition, with high mortality rates, and increased apoptosis of hepatocytes represents a key event in the cause of liver failure. Alpha-1-antitrypsin (AAT) is synthesized and secreted mainly by hepatocytes, and plasma purified AAT is used for augmentation therapy in patients with AAT deficiency. Because AAT therapy exerts antiinflammatory and immune modulatory activities in various experimental models, and it was recently suggested that AAT exerts antiapoptotic activities, we aimed to explore whether administration of AAT may represent a therapeutic strategy to treat acute liver failure in mice. Well-established preclinical models of acute liver failure such as the Jo2 FAS/CD95 activating model and models of acetaminophen and α-amanitin poisoning were used. Therapeutic effects of AAT were evaluated by monitoring animal survival, histopathological changes, measurement of caspase activity, and serum cytokine levels. Systemic treatment with AAT significantly decreased Jo2-induced liver cell apoptosis and prolonged survival of mice. Native and oxidized (lacking elastase inhibitory activity) forms of AAT were equally effective in preventing acute liver injury and showed direct inhibition of active caspase-3 and -8 in liver homogenates and in a cell-free system in vitro. Concomitantly, mice treated with AAT showed significantly lower serum levels of tumor necrosis factor alpha (TNF-α), which also paralleled the reduced activity of ADAM17 (TACE). Noticeably, the increased survival and a reduction of apoptotic hepatocytes were also observed in the α-amanitin and acetaminophen-induced liver injury mouse models., Conclusion: Our data suggest that systemic administration of AAT can be a promising therapy to treat acute liver failure and clinical studies to explore this treatment in humans should be initiated., (© 2014 by the American Association for the Study of Liver Diseases.)

Purpose: Defining an adequate resection margin of colorectal cancer liver metastases is essential for optimizing surgical technique. We have attempted to evaluate the resection margin through a combination of histopathologic and genetic analyses., Experimental Design: We evaluated 88 samples of tumor margins from 12 patients with metastatic colon cancer who each underwent partial hepatectomy of one to six liver metastases. Punch biopsies of surrounding liver tissue were obtained at 4, 8, 12, and 16 mm from the tumor border. DNA from these biopsies was analyzed by a sensitive PCR-based technique, called BEAMing, for mutations of KRAS, PIK3CA, APC, or TP53 identified in the corresponding tumor., Results: Mutations were identified in each patient's resected tumor and used to analyze the 88 samples circumscribing the tumor-normal border. Tumor-specific mutant DNA was detectable in surrounding liver tissue in 5 of these 88 samples, all within 4 mm of the tumor border. Biopsies that were 8, 12, and 16 mm from the macroscopic visible margin were devoid of detectable mutant tumor DNA and of microscopically visible cancer cells. Tumors with a significant radiologic response to chemotherapy were not associated with any increase in mutant tumor DNA in beyond 4 mm of the main tumor., Conclusions: Mutant tumor-specific DNA can be detected beyond the visible tumor margin, but never beyond 4 mm, even in patients whose tumors were larger prior to chemotherapy. These data provide a rational basis for determining the extent of surgical excision required in patients undergoing resection of liver metastases., (©2011 AACR.)

We recently reported a cell death cascade whereby cellular stressors activate nitric oxide formation leading to S-nitrosylation of GAPDH that binds to Siah and translocates to the nucleus. The nuclear GAPDH/Siah complex augments p300/CBP-associated acetylation of nuclear proteins, including p53, which mediate cell death. We report a 52 kDa cytosolic protein, GOSPEL, which physiologically binds GAPDH, in competition with Siah, retaining GAPDH in the cytosol and preventing its nuclear translocation. GOSPEL is neuroprotective, as its overexpression prevents NMDA-glutamate excitotoxicity while its depletion enhances death in primary neuron cultures. S-nitrosylation of GOSPEL at cysteine 47 enhances GAPDH-GOSPEL binding and the neuroprotective actions of GOSPEL. In intact mice, virally delivered GOSPEL selectively diminishes NMDA neurotoxicity. Thus, GOSPEL may physiologically regulate the viability of neurons and other cells.

Tumors other than paragangliomas in the jugular foramen are uncommon. Of these, schwannomas and meningiomas predominate. Little clinical data are available in the literature on these tumors at this site. The purpose of this article is to review our experience at the Gruppo Otologico of the management of these tumors. A retrospective series is presented of 32 consecutive patients affected by jugular foramen schwannomas and meningiomas in which their clinical and radiological signs, together with surgical techniques and outcomes, were reviewed. A single-stage resection was possible for the majority of patients when the petro-occipital trans-sigmoid (POTS) approach was used. This allowed resection of both intra- and extradural components of the tumor with hearing preservation and avoidance of facial nerve transposition. No deaths occurred. Lower cranial nerve palsies constituted the major cause of morbidity, but none of the patients required an adjunctive procedure such as vocal cord medialization, tracheostomy, or percutaneous gastrostomy.
