Abstract
Introduction The objective of this study was to search existing literature on nerve reconstruction surgery in patients with obstetric brachial plexus palsy to determine whether treatment with supraclavicular exploration and nerve grafting produced better elbow flexion outcomes compared to intercostal nerve transfer. Methods This study was a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis for Individual Patient Data guidelines. A systematic search was conducted using multiple databases. An ordinal regression model was used to analyze the effect of using supraclavicular exploration and nerve grafting or intercostal nerve on elbow flexion with the two scores measured: elbow flexion Medical Research Council scores and Toronto active movements scale scores for elbow flexion. Results A final patient database from 6 published articles consisted of 83 supraclavicular exploration and nerve grafting patients (73 patients with Medical Research Council and 10 patients with Toronto score) and 7 published articles which consisted of 131 intercostal nerve patients (84 patients with Medical Research Council and 47 patients with Toronto scores). Patients who underwent supraclavicular exploration and nerve grafting presented with an average Medical Research Council score of 3.9 ± 0.72 and an average Toronto score of 6.2 ± 2.2. Patients who underwent intercostal nerve transfer presented with an average Medical Research Council score of 3.9 ± 0.71 and an average Toronto score of 6.4 ± 1.2. There was no statistical difference between supraclavicular exploration and nerve grafting and intercostal nerve transfer when utilizing Medical Research Council elbow flexion scores (ordinal regression: 0.3821, standard error: 0.4590, p = 0.2551) or Toronto Active Movement Scale score for elbow flexion (ordinal regression: 0.7154, standard error: 0.8487, p = 0.2188). Conclusion Regardless of surgical intervention utilized (supraclavicular exploration and nerve grafting or intercostal nerve transfers), patients had excellent outcomes for elbow flexion following obstetric brachial plexus palsy when utilizing Medical Research Council or Toronto scores for elbow flexion. The difference between these scores was not statistically significant. Type of study/Level of evidence Therapeutic Study: Investigating the Result of Treatment/level III.

Abstract
INTRODUCTION Bowel obstruction is one of the most common surgical emergencies. The management of SBO is variable and influenced by numerous confounding factors. Recent studies have identified mental health as a health disparity that affects surgical outcomes. We aim to assess whether mental illness is a health disparity and its association with postoperative complications and secondary outcomes for bowel obstruction in Emergency General Surgery (EGS). METHODS This was a retrospective study utilizing the National Inpatient Sample. Individuals aged 18-64 who underwent emergency adehesiolysis or bowel resection from 2015 to 2017 were identified. Postoperative complications, in-hospital mortality, length of stay, and total cost for surgical patients with and without mental illness were recorded. Univariate and multivariate analyses were used to evaluate the association between mental health and bowel obstruction. RESULTS 20,574 patients who underwent surgery for bowel obstruction were identified. 3756 of these patients had mental illness and 16,998 patients did not. Patients with mental illness did not have significantly worse outcomes compared to patients without mental illness. Among 3576 patients with mental illness, sex, race, patient location, insurance, location/teaching status of hospital, hospital control and procedure type were significant predictors of prolonged length of stay, higher cost, and increased postoperative complications. CONCLUSIONS Mental health does not appear to be a health disparity in outcomes for bowel obstruction procedures. However, the intersection of mental health with race and insurance status predicts worse outcomes. This essential area should be further explored to determine how marginalized populations are affected in emergency surgical care.

Abstract
BACKGROUND Debate over the optimal age at time of surgery for treatment of brachial plexus birth injury (BPBI) remains controversial, and there exists geographical varia- tion in surgical preference for age at time of surgery. The objective of this review was to analyze trends in age and geography in brachial plexus microsurgery for treatment of brachial plexus birth injury (BPBI) over time. METHODS Review of the literature in this study was con- ducted according to the Preferred Reporting Items for Sys- tematic Reviews and Meta-Analysis (PRISMA) guidelines. PubMed, Cochrane, Web of Science, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases were searched. RESULTS Pediatric patients undergoing brachial plexus microsurgery described in published reports before 2011 had a mean of 7.15 ± 6.56 months of age, while pediatric patients undergoing brachial plexus microsurgery surgery described in published reports after 2011 had a mean of 11.23 ± 9.76 months of age (p < 0.05). The mean age at surgery was lower in publications from Asian countries (6.29 months) than in publications from North America (11.34 months; p < 0.05). CONCLUSIONS Age at time of microsurgery for treatment of BPBI is increasing, with mean age at surgeries occurring in and after 2011 being 4 months higher than thos occuring before 2011. The mean age at surgery was about 5 months higher in North American publications than in Asian pub- lications.

Abstract
Background Neonatal brachial plexus palsy (NBPP) is a serious complication of high‐risk deliveries with controversy surrounding timing of corrective nerve surgery. This review systematically examines the existing literature and investigates correlations between age at time of upper trunk brachial plexus microsurgery and surgical outcomes. Methods A systematic screening of PubMed, Cochrane, Web of Science, and CINAHL databases using PRISMA‐IPD guidelines was conducted in January 2020 to include full‐text English papers with microsurgery in upper trunk palsy, pediatric patients. Spearman rank correlation analysis and two‐tailed t‐tests were performed using individual patient data to determine the relationship between mean age at time of surgery and outcome as determined by the Mallet, Medical Research Council (MRC), or Active Movement Scale (AMS) subscores. Results Two thousand nine hundred thirty six papers were screened to finalize 25 papers containing individual patient data (n = 256) with low to moderate risk of bias, as assessed by the ROBINS‐I assessment tool. Mallet subscore for hand‐to‐mouth and shoulder abduction, AMS subscore for elbow flexion and external rotation, and MRC subscore for elbow flexion were analyzed alongside the respective age of patients at surgery. Spearman rank correlation analysis revealed a significant negative correlation (ρ = −0.30, p < .01, n = 89) between increasing age (5.50 ± 2.09 months) and Mallet subscore for hand‐to‐mouth (3.43 ± 0.83). T‐tests revealed a significant decrease in Mallet hand‐to‐mouth subscores after 6 months (p < .05) and 9 months (p < .05) of age. No significant effects were observed for Mallet shoulder abduction, MRC elbow flexion, or AMS elbow flexion and external rotation. Conclusion The cumulative evidence suggests a significant negative correlation between age at microsurgery and Mallet subscores for hand‐to‐mouth. However, a similar correlation with age at surgery was not observed for Mallet shoulder abduction, MRC elbow flexion, AMS external rotation, and AMS elbow flexion subscores.

Abstract
CD8 T cells contribute to effective clearance of mouse adenovirus type 1 (MAV-1) and to virus-induced pulmonary inflammation. We characterized effects of a CD8 T cell effector, TNF, on MAV-1 pathogenesis. TNF inhibited MAV-1 replication in vitro. TNF deficiency or immunoneutralization had no effect on lung viral loads or viral gene expression in mice infected intranasally with MAV-1. Absence of TNF delayed virus-induced weight loss and reduced histological evidence of pulmonary inflammation, although concentrations of proinflammatory cytokines and chemokines in bronchoalveolar lavage fluid (BALF) were not significantly affected. BALF concentrations of IL-10 were greater in TNF-deficient mice compared to controls. Our data indicate that TNF is not essential for control of viral replication in vivo, but virus-induced TNF contributes to some aspects of immunopathology and disease. Redundant CD8 T cell effectors and other aspects of immune function are sufficient for antiviral and pro-inflammatory responses to acute MAV-1 respiratory infection.

Abstract
BACKGROUND Dengue Fever (DF) is an emerging mosquito-borne disease. It is a nagging public health problem in the low lands of Terai, expanding to new areas of Nepal in recent years. METHODS A cross-sectional study was conducted to determine anti-Dengue IgM positive rate in Mahendranagar, Dhangadi and Dang between August 2008 and November 2009. Serum samples were collected from 283 patients visiting hospitals with history of fever, headache and suspected DF. The samples were examined by ELISA. RESULTS The anti-Dengue IgM positivity was found to be 9.8 %. The positive rate was highest in Mahendranagar (13.3 %) followed by Dhangadi (9.8 %) (P<0.05). The Dengue positive cases were higher in female (10.9 %) than males (9.0 %). The positivity was higher in Ethnic group Brahman/Chherti (13.1%) as compared to Janajati (5.6 %). The highest positive cases (10.7 %) were from age group above 50 years. The highest numbers of Dengue positive cases were observed in occupation group of agriculture (18.2 %) (P>0.05). CONCLUSIONS Dengue has substantial expansion in Western and Far Western Terai region of Nepal which was limited to the middle Terai region in the past and mostly infects older people.

Abstract
A person with low vision has some useful sight. However, low vision usually interferes with the performance of daily activities such as reading or driving. Because low vision cannot be improved by mere traditional methods (i.e., the use of eyeglasses, contact lenses, etc), persons with low vision often rely on the use of a number of different instruments, called low vision devices, and tailored equipment for improved vision. Low vision devices are described in this article.

Abstract
Diltiazem, a calcium channel blocker, and a cardiovascular therapeutic agent offers significant protection to mice against lethal dose of ionizing radiation. Considering the potential efficacy of diltiazem as a radioprotector for human use, it was deemed necessary to investigate its influence on radiation-induced behavioural changes like nausea, vomiting, learning, memory and performance. In the present studies, conditioned taste aversion (CTA) test based on consumption of saccharin solution, was used as a marker of behavioural changes. Significant CTA (97 +/- 2%) was observed in rats irradiated with Co-60 gamma rays (absorbed dose 1 Gy). Administration of diltiazem at doses greater than 10 mg/kg, body wt, evoked CTA in a dose-dependent manner and that was found to be further aggravated on irradiation. At a lower dose of 5 mg/kg, body wt, diltiazem did not evoke CTA and protected against radiation induced aversion significantly (62 +/- 3%). The results suggest that diltiazem at concentrations lower than 10 mg/kg, body wt, in rats may be useful in preventing radiation induced behavioural changes. This observation could be of particular significance in clinical radiotherapy where radiation induced nausea and vomiting are of great concern.

Abstract
The comparative effects of equimolar doses of thyroxine (T4) and tri-iodothyronine (T3) and of the inhibition of peripheral monodeiodination were studied on feather regeneration and moult in thyroidectomized and intact adult male spotted munia (Lonchura punctulata). T4 was significantly more effective than T3 at all dose levels in inducing feather regeneration in thyroidectomized birds. Suppression of monodeiodination by iopanoic acid (IOP) was not accompanied by a suppression of T4-induced feather regeneration in thyroidectomized birds and IOP alone was without effect in thyroidectomized birds. Long-term treatment of intact birds with IOP accelerated the process of moulting by about 3 months. These findings question the prevailing concept that T3 is the finally active biological compound and T4 a mere precursor.

Abstract
In the subtropical finch, spotted munia (Lonchura punctulata), circanual rhythms (of gonads, fattening, feeding) have been demonstrated in an information-free environment of continuous illumination (LL), rendering it an ideal model for research on the physiology of the circannual clock. In an attempt to understand the involvement, if any, of the circadian system in the genesis of circannual rhythms, we studied the effect of pinealectomy (LL 15 lux) and strong continuous illumination (LL 300 lux), both known to abolish circadian rhythms, on the circadian perch-hopping rhythm and on the circannual rhythm of reproduction and fattening in the same birds. While both pinealectomy and LL 300 lux treatments abolished the circadian rhythm of motor activity, they had no effect on the circannual rhythms of gonadal size and fattening. If the endogenous circadian rhythm in perch-hopping can be taken to reflect the circadian clock mechanism associated with gonadal functioning, present results suggest that circannual rhythm of reproduction in spotted munia is independent of circadian events.

Abstract
Fungal studies were conducted on 35 patients with corticosteroid-dependent asthma (CSDA) and 20 asthmatics who had never received prednisolone. Candida albicans was repeatedly cultured from the sputa of 12 patients with CSDA. Isolation was more frequent in those patients who were receiving more than 10 mg prednisolone for more than six months. Nearly half of these patients demonstrated a positive immediate cutaneous reaction and precipitating antibodies against C. albicans. Although no pathological significance, beside colonization, could be attributed to this finding, it was felt that it would be prudent to restrict the daily dose of prednisolone to less than 10 mg, when administered for more than six moths. Two patients with allergic bronchopulmonary aspergillosis (ABPA), were identified, one from each group. The possibility of ABPA, however, remained open in two other patients with CSDA. It is probable that some patients with CSDA may be suffering from ABPA but characteristic features of the disease are masked by costicosteroid therapy, making it difficult to diagnose.

Twenty-four patients suspected to have sarcoidosis were subjected to fibrebronchoscopy. Histopathological support for the diagnosis was ultimately obtained in 20 patients. Fibrebronchoscopy provided the diagnosis in 17 patients, while histopathological confirmation was obtained from extrapulmonary biopsy sites in 3 patients. Transbronchial lung biopsy, attempted without fluoroscopic guidance, revealed non-caseating granulomata in 15 patients. The only complication encountered was a small pneumothorax, not requiring intervention, in one patient. Lack of fluoroscopic guidance did not compromise the diagnostic yield or increase the complication rate of the procedure. Bronchial biopsy confirmed the diagnosis in 2 patients with a non-specific lung biopsy. It was positive in 6 of 8 patients with an abnormal appearing mucosa and in 5 of 12 patients with a normal bronchial tree. Random bronchial biopsy in all patients, irrespective of mucosal changes, made an important contribution to the yield of fibrebronchoscopy. Fibrebronchoscopy confirmed the diagnosis of tuberculosis in 2 patients with an atypical radiological picture, thereby differentiating the two conditions which occasionally mimic each other.

Abstract
A case of pulmonary alveolar microlithiasis (PAM) with pleural calcification and nephrolithiasis is reported. The significance of peripheral white lines, a rarely reported observation on chest roentgenogram in PAM, is discussed. Extrapulmonary calcification in multiple sites raises the possibility of PAM being a systemic disorder.

Abstract
Twenty-two patients with smear-negative miliary tuberculosis underwent fiberbronchoscopy and brush smears; bronchial aspirates and transbronchial lung biopsy specimens were obtained. A definite diagnosis of tuberculosis was made in 16 (73 percent) patients. A rapid diagnosis was established in 14 of these 16 patients either from brush smears alone (three) or bronchial aspirate smear alone (one) or exclusively by histopathologic study of biopsy specimens (seven). Both brush smears and biopsy histopathology results provided the diagnosis in three patients. Bronchial aspirate culture was the only positive specimen in two patients. No serious complication resulted from the procedure. Our experience substantiates previous reports of the value and safety of fiberbronchoscopy in the rapid diagnosis of smear-negative miliary tuberculosis.

Abstract
An unusual case of primary mediastinal tuberculous abscess is presented in whom the diagnosis was obtained on magnetic resonance (MR) and ultrasound (US) guided aspiration cytology. Mycobacterium tuberculosis was isolated from direct smear as well as from culture of the "pus". Normal spine signal with MR and normal bone scintigraphy excluded any vertebral focus of infection. MR was helpful in, defining the extent and characterising the abscess, besides excluding a vertebral focus of infection.

Abstract
Fifty smear-negative pulmonary tuberculosis patients underwent fibreoptic bronchoscopy. Bronchial aspirate smears of twelve patients and post-bronchoscopic sputum smears of fourteen patients were positive for acid-fast bacilli (AFB). Bronchial biopsy provided the diagnosis in 9 out of 30 patients. Brush smears were positive in 28 patients, being the only positive sample in ten cases. A high yield from brush smears was obtained due to their preparation from caseous material wherever visible in the bronchi. With these results a rapid diagnosis was established in 36 of the 50 patients. When culture results were available, a definite diagnosis of tuberculosis was made in 45 of the patients. The yield from brush smears was found to be significantly better when compared to bronchial aspirate smears (p less than 0.01) and post-bronchoscopic sputum smears (p less than 0.01).
