Abstract
PURPOSE To better understand the manner in which outcomes are reported after brachial plexus reconstruction, we conducted a systematic review of the scientific literature. METHODS We included English-language articles describing treatment of brachial plexus injuries to restore motor function of the shoulder, elbow, forearm, and/or wrist with nerve repair, nerve graft, and/or nerve transfer. We recorded the anatomical location of injury, the treatment used, and the manner in which motor function, active and passive range of motion, pain, quality of life, function or disability, patient satisfaction, and psychosocial health was reported. RESULTS In reviewing 88 papers with outcomes for 5,189 patients, 83 (94%) of the papers reported postoperative motor function. Of these, 49 (59%) did not include any other measures of patient outcome. Active range of motion was reported in 24 (27%) studies, pain was reported in 15 (17%) studies, quality of life was reported in 4 (5%) studies, function or disability was reported in 5 (6%) studies, patient satisfaction in 3 (3%) studies, and psychosocial health in 1 study. CONCLUSIONS To date, outcome reporting for brachial plexus surgery has largely centered on motor recovery and typically has not included measures of function or nonmusculoskeletal recovery. Incorporating currently used measures of physical recovery with patient-derived outcomes measures such as quality of life, function, pain, and satisfaction will likely help provide a more comprehensive understanding of the effect of brachial plexus reconstruction surgery. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic III.

Abstract
BACKGROUND The use of sevoflurane without muscle relaxant for tracheal intubation has been widely investigated in children. Non-depolarizing neuromuscular blockers have long duration of action and do not provide rapid return of spontaneous ventilation. Use of suc-cinylcholine has been found to be associated with various side-effects especially in children. Therefore, we aim to evaluate the effect of propofol 1.5 mg/kg without muscle relaxant, on intubating conditions in children 2-8 yrs of age and we compare them with those achieved with rocuronium 0.6 mg/kg, at moderate sevoflurane concentration. METHODS Fifty children between 2-8 yrs, ASA I or II scheduled for elective surgery were randomly allocated to either Group P (propofol) or group R (rocuronium). After premedication with oral midazolam 0.5 mg/kg 30 min before surgery, anaesthesia was induced with 8% sevoflurane in oxygen. Intravenous fentanyl 1 µg/kg was administered after securing intravenous access and dial concentration of sevoflurane was reduced to 4%. At one minute with regards to time T₀, the patients received the drug which was either intravenous rocuronium 0.6 mg/kg or an equal volume of 0.9% saline (D) and at three minutes (two minutes after D₁), second drug (D₂) was given, which was either propofol 1.5 mg/kg or an equal volume of 0.9% saline according to the group allocated. At four minutes, laryngoscopy was done and intubation performed with appropriate sized uncuffed endotracheal tube. Incidence of acceptable and excellent intubating conditions, time to intubation and hemodynamic parameters were recorded. RESULTS Incidence of acceptable or excellent intubating conditions was similar in both groups (p = 1.00). The difference in time to intubation was statistically not significant (25.03 ± 6.05s in Group P and 24.38 ?5.58s in Group R, p = 0.694), at similar end-tidal concentration of sevoflurane (3.2 ± 0.20% in Group P and 3.1 ± 0.20% in Group R, p = 0.12). CONCLUSION Propofol (1.5 mg/kg) and rocuronium (0.6 mg/kg) produced similar intubating conditions in children induced with sevoflurane.

Abstract
Accurate determination of cell number is essential for the quantitative description of biological processes. The changes should be related to a measurable reference e.g. in the case of cell culture, the viable cell number is a very valuable reference parameter. Indirect methods of cell number/viability measurements may have up to 10 % standard deviation. This can lead to undesirable large deviations in the analysis of "-omics" data as well as time course studies. Such data should be preferably normalized to the exact viable cell number at a given time to allow meaningful interpretation and understanding of the biological processes. Manual counting of cell number is very laborious and not possible in certain experimental setups. We therefore, developed a simple and reliable fluorescence based method with an accuracy of 95-98 % for the determination of the viable cell number in situ. We optimized the seeding cell densities for primary rat hepatocytes for optimal cell adhesion. This will help in efficient use of primary cells which are usually limited in availability. The method will be very useful in the application of "-omics" techniques, especially metabolome analysis where the specific rates of uptake/production of metabolites can be reliably calculated.

Abstract
Since their discovery in the late 1970s, protein kinase C (PKC) isozymes represent one of the most extensively studied signaling kinases. PKCs signal through multiple pathways and control the expression of genes relevant for cell cycle progression, tumorigenesis and metastatic dissemination. Despite the vast amount of information concerning the mechanisms that control PKC activation and function in cellular models, the relevance of individual PKC isozymes in the progression of human cancer is still a matter of controversy. Although the expression of PKC isozymes is altered in multiple cancer types, the causal relationship between such changes and the initiation and progression of the disease remains poorly defined. Animal models developed in the last years helped to better understand the involvement of individual PKCs in various cancer types and in the context of specific oncogenic alterations. Unraveling the enormous complexity in the mechanisms by which PKC isozymes have an impact on tumorigenesis and metastasis is key for reassessing their potential as pharmacological targets for cancer treatment.

Abstract
OBJECTIVE This study aimed to evaluate the relationship between nasopharyngeal pH and Eustachian tube dysfunction (ETD) in adults. STUDY DESIGN Unmatched case-control study. METHODS Forty-one subjects, 20 adults with a diagnosis of ETD and 21 healthy adults as controls, were enrolled from an outpatient clinic. All subjects had a Dx-pH probe placed near the torus tubarius in the posterior nasopharynx for 24 hours. The pH values were recorded every 0.5 second. Decreases in pH were considered as reflux events if the pH dropped below 5.5. RESULTS The average nasopharyngeal pH value was 6.90 (range, 5.33-7.73) in the subjects with ETD and 7.07 (range, 5.99-7.94) in the controls. The difference between the 2 groups was not statistically significant (P = .30). The ETD group, on average, had a higher number of nasopharyngeal reflux events (2.3 +/- 1.6 vs 0.8 +/- 1.2, respectively; P = .002) and higher reflux finding score (3.6 +/- 2.7 vs 0.4 +/- 1.4, respectively; P < .00 I) than the control group. CONCLUSION By using a novel pH probe that allows detection of acidity in a nonliquid environment, a comparison of nasopharyngeal pH between control patients and those with ETD was performed. Eustachian tube dysfunction was more likely to be associated with a higher number of nasopharyngeal reflux events and higher reflux finding score. Nasopharyngeal reflux may have a role in the pathogenesis of ETD.

Abstract
BACKGROUND Airway secretions contain endogenous antimicrobial factors (AMFs) that contribute to the innate host defense of the respiratory tract. Antibacterial peptides as well as host-derived lipids including cholesteryl esters have been detected in maxillary lavage fluid. Sterol O-acyltransferase 1 (SOAT1) is a key enzyme in cholesteryl ester production. The purpose of this study is to determine if such intrinsic microbicidal molecules are acutely expressed within sinus tissue and to compare levels of expression between patients with and without chronic rhinosinusitis (CRS). METHODS Sinus tissue was obtained from subjects with (24) and without (9) a history of CRS. Six CRS patients had nasal polyposis (CRSwNP). Immunofluorescence staining for human neutrophil peptide (HNP) was done as a marker for inflammation. Real-time polymerase chain reaction (RT-PCR) following RNA extraction was used to quantify the expression of SOAT-1, the epithelial beta-defensins (HBD2 and HBD3), and the cathelicidin LL37 with ribosomal protein, large, P0 (RPLP0) as the housekeeping gene. RESULTS Immunofluorescence showed significant increase in HNP staining in CRS patients without nasal polyposis (CRSsNP) vs non-CRS specimens (p = 0.010), in agreement with clinical inflammation status. SOAT1 messenger RNA (mRNA) expression was also upregulated in CRSsNP compared to non-CRS (p = 0.041) and CRSwNP (p = 0.005) patients, whereas increases for HBD2 and HBD3 were less prominent. LL37 was either absent or expressed at very low levels in all samples. CONCLUSION Increased biosynthesis of SOAT1, a key enzyme for antimicrobial cholesteryl ester production, was observed in the sinus tissue of CRSsNP patients but not in CRSwNP patients. This further supports the novel concept of lipid-mediated innate mucosal defense and delineates CRS with and without nasal polyposis as distinct subtypes.

Abstract
PURPOSE To quantify the coupled motion of the wrist during selected functional tasks and to determine the effects of constraining this coupled motion using a radial-ulnar deviation blocking splint on performance of these tasks. METHODS Ten healthy, right-handed men performed 15 trials during selected functional tasks with and without a splint, blocking radial and ulnar deviation. The following tasks were performed: dart throwing, hammering, basketball free-throw, overhand baseball and football throwing, clubbing, and pouring. Kinematic coupling parameters (coupling, kinematic path length, flexion-extension range of motion, radial-ulnar deviation range of motion, flexion-extension offset, and radial-ulnar deviation offset) and performance were determined for each functional task. A generalized estimation equation model was used to determine whether each kinematic coupling parameter was significantly different across tasks. A repeated-measures generalized estimation equation model was used to test for differences in performance and kinematic coupling parameters between the free and splinted conditions. RESULTS Wrist motion exhibited linear coupling between flexion-extension and radial-ulnar deviation, demonstrated by R(2) values from 0.70 to 0.99. Average wrist coupling and kinematic path lengths were significantly different among tasks. Coupling means and kinematic path lengths were different between free and splinted conditions across all tasks other than pouring. Performance was different between wrist conditions for dart throwing, hammering, basketball shooting, and pouring. CONCLUSIONS Wrist kinematic coupling parameters are task specific in healthy individuals. Functional performance is decreased when wrist coupling is constrained by an external splint. CLINICAL RELEVANCE Surgical procedures that restrict wrist coupling may have a detrimental effect on functional performance as defined in the study. Patients may benefit from surgical reconstructive procedures and wrist rehabilitation protocols designed to restore kinematic coupling.

Abstract
BACKGROUND A large number of persons with psychiatric disorders are not seeking treatment due to various reasons, thus contributing to the huge treatment gap. One of the ways to bring these people into treatment is through telephonic helplines. MATERIALS AND METHODS Following a large number of suicides in the city of Chandigarh in 2003, The department of Psychiatry, GMCH, Chandigarh was designated as nodal center for the prevention of suicide. A 24-hour suicide prevention helpline was set up as an immediate measure to help persons in crisis. Apart from providing telephonic counseling to persons in crisis, the helpline coordinated with police, media, schools, radio stations etc., to reduce the number of suicides in the city. RESULTS Majority of the callers were males (65.93%), between 20 to 39 years old (56.34%), married (79.50%), had less than 12 years of formal education (60.68%), and were earning less than Rs. 5000/month (56.80%). 72.96% callers had contacted the mental health services for the first time. A significant number of persons (434, 13.26%) called the helpline for marital, academic, stress-related problems. Majority of the calls were received between 8 A.M. and 2 P.M. The number of suicides in the city of Chandigarh showed a decline in the following years since the helpline was set up. CONCLUSIONS The telephonic helpline seems to be a very effective way of getting persons into contact with health services. They are cost-effective, the person can maintain his confidentiality and devoid of stigma.

Abstract
AIM Obese individuals have high aldosterone levels that may contribute to insulin resistance (IR) and endothelial dysfunction leading to obesity-induced cardiovascular disease. We conducted a study to evaluate the effect of mineralocorticoid receptor antagonism on IR and endothelial function in obese individuals. This was a placebo-controlled, double-blind, randomized, parallel-group study (NCT01406015). METHODS Thirty-two non-diabetic, obese subjects [body mass index (BMI) 30 to 45 kg/m(2) ] with no other medical problems were randomized to 6 weeks of treatment with spironolactone 50 mg daily or placebo. Insulin sensitivity index (ISI) was assessed by Matsuda method, endothelial function by flow mediated vasodilatation (FMD) of brachial artery and renal plasma perfusion by clearance of para-aminohippurate (PAH). RESULTS There was no change in weight, BMI or plasma potassium during the study period. Treatment with spironolactone led to increases in serum aldosterone (7.6 ± 6.6 vs. 3.2 ± 1.3 ng/dl; p < 0.02, post-treatment vs. baseline) and urine aldosterone (11.0 ± 7 vs. 4.8 ± 2.4 µg/g creatinine; p < 0.01) and decreases in systolic blood pressure (116 ± 11 vs. 123 ± 10 mmHg; p < 0.001). There were no changes in these variables in the placebo group. Neither spironolactone nor placebo treatment had a significant effect on ISI or other indices of glucose metabolism [insulin resistance by homeostatic model assessment (HOMA), area under the curve for insulin, area under the curve for glucose], brachial artery reactivity or the renal plasma perfusion values. Changes in these variables were similar in two groups. CONCLUSIONS We conclude that 6 weeks of treatment with spironolactone does not change insulin sensitivity or endothelial function in normotensive obese individuals with no other comorbidities.

Abstract
Respiratory syncytial virus (RSV) is one of the primary causative agents of upper and lower respiratory tract infections in young children, in particular infants. Recently, we reported the protective efficacy of a RSV vaccine formulation consisting of a truncated version of the fusion (F) protein formulated with a Toll-like receptor (TLR) agonist and an immunostimulatory peptide in a carrier system (ΔF/TriAdj). To evaluate the duration of immunity induced by this vaccine candidate, we carried out long-term trials. The ΔF was formulated with triple adjuvant (TriAdj) containing either polyinosinic : polycytidylic acid (polyI : C) or cytosine-phosphate-guanosine oligodeoxynucleotides (CpG ODNs) and administered intranasally to mice. One year after the second vaccination all mice were challenged with RSV. Both ΔF/TriAdj formulations mediated the induction of high levels of IgG1, IgG2a and virus-neutralizing antibodies, and IgA in the lungs. Based on the numbers of IFN-γ- and IL-5-secreting cells in the spleen, the immune response was slightly T-helper cell type 1 (Th1)-biased. This was confirmed by the presence of F85-93-specific CD8(+) effector T cells in the lungs of both ΔF/TriAdj(polyI : C)- and ΔF/TriAdj(CpG)-immunized mice. Both ΔF/TriAdj formulations induced RSV-specific CD8(+) T cells. However, ΔF/TriAdj(polyI : C) generated significantly higher IgG affinity maturation and higher numbers of RSV-specific CD8(+) effector memory T cells in lungs and CD8(+) central memory T cells in spleen and lymph nodes than ΔF/TriAdj(CpG). After RSV challenge, no virus replication and no evidence of vaccine-induced pathology were detected in mice immunized with either of the ΔF/TriAdj formulations, demonstrating that the duration of immunity induced with these vaccines is at least one year.

Abstract
Excited states in 102Rh, populated in the fusion-evaporation reaction Zr94(11B,3n)102Rh at a beam energy of 36 MeV, were studied using the Indian National Gamma Array spectrometer at Inter University Accelerator Center, New Delhi. The angular correlations and the electromagnetic character of some of the gamma-ray transitions observed were investigated in detail. A new chiral candidate sister band was found. Lifetimes of exited states in both chiral candidate bands of 102Rh were measured for the first time in the A∼100 mass region by means of the Doppler-shift attenuation technique. The derived reduced transition probabilities are compared to the predictions of the two quasiparticles plus triaxial rotor model. Both experimental results and calculations do not support the presence of static chirality in 102Rh.

The Hadad-Bassagasteguy vascularized nasoseptal pedicled flap (HBF) is an effective technique for reconstruction of skull base defects with low incidence of postoperative cerebrospinal fluid (CSF) leak. Advanced planning is required as posterior septectomy during transsphenoidal surgery can preclude its use due to destruction of the vascular pedicle. We present four cases in which the HBF was successfully used to repair recurrent CSF leaks despite prior posterior septectomy and transsphenoidal surgery. A retrospective chart review was performed on all patients who developed recurrent CSF leak after transsphenoidal surgery over a 7-year period (2006–2013). Data were collected regarding demographics, clinical presentation, intraoperative findings, and surgical outcomes. Four patients who developed recurrent CSF drainage after transsphenoidal surgery were managed with HBF reconstruction during the study period. Two were men and two were women with a mean age of 37 years (range, 24–48 years). All had previously undergone resection of a pituitary macroadenoma via a transsphenoidal approach, with intraoperative CSF leaks repaired using multilayered free grafts. Recurrent CSF rhinorrhea arose 0.37–12 months (mean, 2.98 months) after the initial pituitary surgery. Active CSF drainage could be visualized intraoperatively with posterior septal perforations present. The HBF was successfully used in all cases, with no evidence of recurrent CSF leak after a mean follow-up of 2.35 years. The HBF may be salvaged for repair of recurrent CSF leaks even in the context of prior posterior septectomy and transsphenoidal surgery. However, longer follow-up is necessary to determine the long-term efficacy of this procedure in such revision cases.

Abstract
Chronic rhinosinusitis (CRS) can lead to serious long-term adverse sequelae, particularly if left untreated. The aim of this study was to describe a series of intracranial mucoceles (ICMs) that arose in the context of longstanding CRS combined with a review of the pertinent literature. A retrospective chart review was performed on all patients who developed ICMs in association with CRS between 2003 and 2012. The clinical presentation, radiographic features, surgical approach, intraoperative findings, and patient outcome were examined in the context of a literature review. Sixty-five cases of mucoceles were identified in patients with a history of CRS, of which seven (10.8%) were intracranial. Five patients were men and two were women with a mean age of 42.1 years. Headache, facial pressure, retro-orbital pain, and visual disturbances were the most common presenting symptoms. Five of the seven had previously undergone sinonasal surgery. Imaging studies showed ICMs involving the anterior cranial fossa, two of which were bilateral. Latency between onset of CRS and ICM detection ranged from 3 to 19 years (mean, 9.4 years). All patients underwent endoscopic transnasal drainage with three also requiring a concurrent, open neurosurgical procedure to access the intracranial component. There were no postoperative complications, and no recurrences were observed after a mean follow-up of 2.7 years. ICMs presenting as delayed complications of CRS are uncommon and constitute a surgical challenge. Open, external skull base approaches used in conjunction with transnasal endoscopic drainage procedures may be necessary to achieve successful management of this rare condition.
