    A 21 year old female, suffered accidental burns in April 2008 resulting in severe soft tissue contractures and bony ankylosis of both elbows. She was disabled with both nonfunctional upper extremities and reported to our center with deformity and dysfunction of both elbows for past 02 years. On evaluation her elbows were fixed in 40° flexion on right side and 30° flexion on left side. She was completely dependent on her mother for her daily activities like feeding and hygiene care, though she had acceptable wrist and hand function. She was managed with interposition arthroplasty with ipsilateral autogenous tensor fascia lata graft on both elbows. At 5 year follow-up, she has pain free elbows with functional range of motion and no neurovascular deficits. She is able to use both upper extremities for all activities of daily living. Most importantly she is independent and has taken up a job for her livelihood

    Objectives: To evaluate patients of benign prostatic hyperplasia (BPH) preoperatively and identify those who would benefit from surgery, to evaluate outcome of surgery for BPH with respect to symptomatic and objective improvement of patients, and to compare the results of different surgeries for BPH being done different hospitals at Bhopal, which included transurethral resection of the prostate (TURP), transurethral incision of prostate (TUIP)/bladder neck incision (BNI), and Freyer’s prostatectomy? Methods: The present study was carried out at different hospitals of Bhopal. Patients presenting to the surgery outpatient department with symptoms of obstruction, namely, weak urinary stream, frequency hesitancy, intermittency, urgency, nocturia, etc., were included in the study. Some of the subjects included were patients presenting during emergency timings with complaints of retention of urine or occasionally other symptoms. The American Urological Association (AUA) Symptom Index questionnaire was administered to all such patients. They were also evaluated by ultrasound examination and patients having BPH on ultrasound (USG) were further evaluated by uroflowmetry. Results: Prostatic weight correlated well with the maximum urinary flow rates with an inverse relationship. Both maximum and average urinary flow rates (Q max and Qav) were improved by all the three surgeries However, TURP and Freyer’s prostatectomy showed greater improvement as compared to TUIP/BNI. Combination of AUA scoring, USG, and uroflowmetry helped us document improvement in our BPH patients and compared it favorably with other studies. Conclusion: Uroflowmetry was a simple assessment tool easy to learn and use. It was also inexpensive and formed a useful extension to clinical examination providing objective evidence of obstruction. It also helped to indirectly quantity the severity of obstruction. Symptom severity did not correlate with prostate size. Small prostates caused symptoms in the severe range also while even large prostates sometimes caused little symptoms. Prostatic weight correlated well with the maximum urinary flow rates with an inverse relationship

    We delineate the role of rotation and spin in physics, discussing in order Newtonian classical physics, special relativity, quantum mechanics, quantum electrodynamics and general relativity. In the latter case, we discuss the generalization of the Kepler formula to post-Newtonian order (c2(c^{-2}) including spin effects and two-body effects. Experiments which verify the theoretical results for general relativistic spin-orbit effects are discussed as well as efforts being made to verify the spin-spin effects

    Objective: The importance of this research work is to design a library of novel coumarin derivatives by docking evaluation of the designed coumarin derivatives as squalene synthase inhibitor.Methods: The three-dimensional structure of designed molecules of squalene synthase inhibitors was collected from Protein Data Bank. The designed molecules were docked onto the enzymes that are squalene synthase inhibitor - 3WCM, 3WCJ, and 3Q2Z protein using SYBYL-X 2.1. Using a standard protocol, the protein was subjected to minimization and protomol generation.Results: By this method, we visualized the possible binding and also estimated the protein interactions with our intended coumarin library, using SYBYL-X 2.1 software. Into the active site of the selected enzymes, all the 20 coumarins were docked and then the docking scores revealed that the compounds possess high affinity toward the selected enzymes.Conclusion: With the help of virtual evaluation, we have elaborated a fast synthetically accessible coumarin-based compounds, and it is an advanced and original scaffold in the area of probable human squalene synthase inhibitors. Some of the developed compounds show better binding property than ligand, and in 3q2Z, the compound 5d shows better binding property than the protein. Furthermore, 6g and 6c have good binding property. In 3 WCM, the compound 6f has better property. In 3 WCJ, the compounds 6g and 6f show better binding property than the protein

    Fluoroquinolones and isoniazid-resistant tuberculosis: implications for the 2018 WHO guidance.

    INTRODUCTION: 2018 World Health Organization (WHO) guidelines for the treatment of isoniazid (H)-resistant (Hr) tuberculosis recommend a four-drug regimen: rifampicin (R), ethambutol (E), pyrazinamide (Z) and levofloxacin (Lfx), with or without H ([H]RZE-Lfx). This is used once Hr is known, such that patients complete 6 months of Lfx (≥6[H]RZE-6Lfx). This cohort study assessed the impact of fluoroquinolones (Fq) on treatment effectiveness, accounting for Hr mutations and degree of phenotypic resistance. METHODS: This was a retrospective cohort study of 626 Hr tuberculosis patients notified in London, 2009-2013. Regimens were described and logistic regression undertaken of the association between regimen and negative regimen-specific outcomes (broadly, death due to tuberculosis, treatment failure or disease recurrence). RESULTS: Of 594 individuals with regimen information, 330 (55.6%) were treated with (H)RfZE (Rf=rifamycins) and 211 (35.5%) with (H)RfZE-Fq. The median overall treatment period was 11.9 months and median Z duration 2.1 months. In a univariable logistic regression model comparing (H)RfZE with and without Fqs, there was no difference in the odds of a negative regimen-specific outcome (baseline (H)RfZE, cluster-specific odds ratio 1.05 (95% CI 0.60-1.82), p=0.87; cluster NHS trust). Results varied minimally in a multivariable model. This odds ratio dropped (0.57, 95% CI 0.14-2.28) when Hr genotype was included, but this analysis lacked power (p=0.42). CONCLUSIONS: In a high-income setting, we found a 12-month (H)RfZE regimen with a short Z duration to be similarly effective for Hr tuberculosis with or without a Fq. This regimen may result in fewer adverse events than the WHO recommendations

    Abdominal tuberculosis continues to be a major public health problem worldwide and poses diagnostic and therapeutic challenges to general surgeons practicing in resource-limited countries. This study was conducted to describe the clinicopathological profile and outcome of surgical treatment of abdominal tuberculosis in our setting and compare with what is described in literature. A prospective descriptive study of patients who presented with abdominal tuberculosis was conducted at Bugando Medical Centre (BMC) in northwestern Tanzania from January 2006 to February 2012. Ethical approval to conduct the study was obtained from relevant authorities. Statistical data analysis was performed using SPSS version 17.0. Out of 256 patients enrolled in the study, males outnumbered females. The median age was 28 years (range = 16-68 years). The majority of patients (77.3%) had primary abdominal tuberculosis. A total of 127 (49.6%) patients presented with intestinal obstruction, 106 (41.4%) with peritonitis, 17 (6.6%) with abdominal masses and 6 (2.3%) patients with multiple fistulae in ano. Forty-eight (18.8%) patients were HIV positive. A total of 212 (82.8%) patients underwent surgical treatment for abdominal tuberculosis. Bands /adhesions (58.5%) were the most common operative findings. Ileo-caecal region was the most common bowel involved in 122 (57.5%) patients. Release of adhesions and bands was the most frequent surgical procedure performed in 58.5% of cases. Complication and mortality rates were 29.7% and 18.8% respectively. The overall median length of hospital stay was 32 days and was significantly longer in patients with complications (p < 0.001). Advanced age (age ≥ 65 years), co-morbid illness, late presentation, HIV positivity and CD4+ count < 200 cells/μl were statistically significantly associated with mortality (p < 0.0001). The follow up of patients were generally poor as only 37.5% of patients were available for follow up at twelve months after discharge. Abdominal tuberculosis constitutes a major public health problem in our environment and presents a diagnostic challenge requiring a high index of clinical suspicion. Early diagnosis, early anti-tuberculous therapy and surgical treatment of the associated complications are essential for survival

    Genes Are Often Sheltered from the Global Histone Hyperacetylation Induced by HDAC Inhibitors

    Histone deacetylase inhibitors (HDACi) are increasingly used as therapeutic agents, but the mechanisms by which they alter cell behaviour remain unclear. Here we use microarray expression analysis to show that only a small proportion of genes (∼9%) have altered transcript levels after treating HL60 cells with different HDACi (valproic acid, Trichostatin A, suberoylanilide hydroxamic acid). Different gene populations respond to each inhibitor, with as many genes down- as up-regulated. Surprisingly, HDACi rarely induced increased histone acetylation at gene promoters, with most genes examined showing minimal change, irrespective of whether genes were up- or down-regulated. Many genes seem to be sheltered from the global histone hyperacetyation induced by HDACi
