AMR Sign - An Arthroscopic S-shaped Fold Signifying Adequate Medial Meniscus Repair

@#Introduction: The preferred management of medial meniscus tears has notably moved from meniscectomies towards repair. With a higher volume of meniscal repairs being done all across the world with every passing day, the lack of an objective and definitive sign suggesting the adequacy of its repair is daunting. The purpose of our study was to introduce a unique and novel arthroscopic sign formed after adequate repair of the medial meniscus, the AMR (Adequacy of Medial meniscus Repair) sign. We hypothesised that it is not only the objective end point for repair, but can also form the indicator for excellent clinical, functional, and radiological outcome even in the long term. Materials and methods: This was a multicentric, prospective study initiated by the corresponding author, and the findings validated subsequently by the other authors. Overall, it included 804 patients of isolated medial meniscus tear operated with arthroscopic all-inside technique between January 2014 and December 2017. Patients were segregated into three groups based on whether an S-shaped curve in the free, inner edge of the medial meniscus sign was formed post-repair, lost after further tightening, or not formed upon subjective completion of repair. All the patients were followed-up and evaluated based of medial joint line tenderness, McMurray’s test for medial meniscus, IKDC score, WOMET score, and radiologically using an MRI at the terminal follow-up. Results: The mean terminal follow-up was 42.34±4.54 months. There was significant (p<0.01) improvement in all patients at the terminal follow-up post-surgery, irrespective of the group. The group in which AMR sign was formed and maintained showed a significantly better functional outcome on terminal follow-up as well as lower failure rates compared to the other two groups. Conclusion: AMR sign is an S-shaped fold at the inner, free edge of medial meniscus, formed after an adequate repair of isolated medial meniscus tear, as viewed on arthroscopy. It is an objective sign denoting regained integrity of the collagen architecture of the medial meniscus following repair. It is also a reliable indicator of excellent long term functional, clinical, and radiological outcome and also lower failure rates in patients after arthroscopic medial meniscus repair.

Differences in COVID-19 mortality in males and females: Is estrogen hormone attributing to sex differences?

Objectives: Globally, the case fatality ratio is more in males versus females. Some studies have suggested estrogen hormone decreases susceptibility to SARS CoV-2. We have analyzed the observed sex differences in COVID-19 behavior in males and females and the clinical profiles of females of different age groups of COVID-19 patients and discussed their symptoms, laboratory evaluations, and associated comorbidities. Material and Methods: The patients were tested for COVID-19 through real-time RT-PCR (Reverse Transcription Polymerase Chain Reaction) assay. The data obtained were studied for the epidemiological, clinical, and laboratory characteristics from their medical records. Results: The mortality rate in females was 12.33% (36/292) whereas mortality in males was 19.63% (84/428). In between group analysis, 8.7% (14/161) of females died in the <40 years age group versus 16.8% (22/131) in more than 40 years age group whereas in males, the mortality was 13.7% (21/153) in <40 years versus 22.9%(63/275). The mortality rate in women older than 40 years was greater than mortality in younger females emphasizing the protection provided by estrogen hormone in them. The proportion of patients who expired due to COVID-19 significantly differs by age cutoff of 40 years, X2 (1, n = 428). The difference is statistically significant at P < 0.05. Males more than 40 years are more likely to expire. Conclusion: Sex-related differences in coronavirus pandemic have been found pointing toward the protective role of estrogen hormone and other differences in immunological behavior in males and females. Downregulation of ACE2 expression, thereby reducing viral entry, might also be contributory to decreasing mortality in females.

Epidermal growth factor receptor mutations in adenocarcinoma lung: Comparison of techniques for mutation detection

Background: Targeted therapy using tyrosine kinase inhibitors in cases of non-small-cell lung carcinoma (NSCLC) that harbor epidermal growth factor receptor (EGFR) mutations has drastically improved the overall survival rate. The current study estimated the frequency of EGFR mutations in the Indian population by analyzing the diagnostic parameters of various techniques available for the detection of these mutations. Materials and Methods: A case series of 100 histologically diagnosed and immunohistochemically confirmed NSCLC with the adenocarcinoma phenotype comprises the study sample. EGFR mutations were detected using clone-specific immunohistochemistry (IHC), real-time polymerase chain reaction (PCR), and Sanger sequencing. Results: EGFR mutations were identified in 48% cases with 72.78% mutations involving exon 19. Clone-specific IHC had a low sensitivity of 46.43%, and the specificity was 79.17%. Sanger sequencing yielded interpretable results in 16% cases only, which were in concordance with the results of real-time PCR. Conclusion: EGFR mutations are increasingly being explored for targeted therapy and personalized medicine. Real-time PCR was found to be the best and the most accurate method for the detection of somatic EGFR mutations in adenocarcinoma primarily in the lungs.

Comparison of prices of commonly used drugs in AMRIT pharmacy, Jan Aushadhi Centre and Private chemist shop: An analytical study from a tertiary care centre in Haryana

Background: The price of medicine in India has always been a point of discussion in public domain. The price range of the same drug is very large with more than 100% difference between various brands available in different settings. Aims and Objectives: To assess the price of different drugs at Jan Aushasdhi (JA), AMRIT and Private Chemist and to compare the prices of these three outlets so that the issues. Material and Methods: This institution-based cross-sectional study was carried out from May 2019 to June 2019. A pretested proforma was prepared to compare the prices of 284 different medicines in Jan Aushadhi, AMRIT and private chemist shops. The collected data were entered in an Excel spreadsheet and presented in Proportions, percentages, and mean. Results: The price of 284 medicines were compared from JA (Median(IQR)- 15.18(18.75) INR) and Private chemist shop (Median(IQR)-88(111.5) INR) while 249 medicine from AMRIT (Median(IQR)-61.05(78.33) INR). Although the majority of the AMRIT drugs are cheaper than the chemist shop except for 31% of Antipsychotic drugs, 26.6% of antihypertensives, 25% of respiratory drugs, 25% of steroids, 21.9% of antibiotics. Conclusion: We concluded that JA is providing drugs cheaper than AMRIT and Private chemist . The prices of medicines offered at AMRIT are lower than market pricing but they are costlier when compared to JA prices.

Central corneal thickness and corneal diameter in preterm and term newborns and preterm neonates at term

Purpose: To record central corneal thickness and corneal diameter in preterm and term newborns within first week of their birth and in preterm neonates at term age. Methods: Babies born at ?34 weeks of gestation period (n = 100), term babies who have a gestation period of >37 weeks (n = 100) and preterm neonates at term age (38-42 weeks) who were born at ?34 weeks (n = 100) were included in this hospital based observational descriptive study. Corneal diameter was taken by Castroviejo Calipers. Central corneal thickness was measured using portable ultrasonic pachymeter (Pachette 3). Refractive status of the eyes was measured using streak Wellch Allyn retinoscope under cyclopentolate cycloplegia. Results: Measure of central corneal thickness and corneal diameter in preterm newborns was found to be 633.5 ± 2.8 ?m and 8.1 ± 0.6 mm, in full term newborns it was 555.1 ± 2.7 ?m and 9.5 ± 0.6 mm, and in preterm neonates at term age, it was 563.5 ± 2.5 ?m and 9.6 ± 0.5 mm, respectively. Mean central corneal thickness was found to be more in preterm newborns 633.5 um then term newborns 555.1 um and the difference was statistically significant (P =0.001). Mean corneal diameter was found to be maximum (9.6 mm) in preterm neonates at term age. Conclusion: Preterm babies have thick corneas and small corneal diameters. This study is useful with respect to the analysis of glaucoma in children and using preterm corneas as donor corneas in penetrating keratoplasty.

ROS-1 re-arrangements and c-MET amplifications in adenocarcinoma lung: A tertiary care center study from North India

Background: C-ros oncogene 1, receptor tyrosine kinase (ROS 1) proto-oncogene 1, receptor tyrosine kinase (ROS-1) fusions are potent oncogenic drivers and these re-arrangements promote signal transduction programs leading to uninhibited cell survival and proliferation identified in 1–2% of cases of nonsmall-cell lung cancer. Mesenchymal epithelial transition factor (MET) receptor tyrosine kinase and its ligand are predominantly involved in epithelial mesenchymal transition and tissue regeneration. The MET amplification and overexpression is oncogenic in 3–7% cases. The objectives of this study were to identify the frequency of ROS-1 and c-MET protein expression in adenocarcinoma lung and to correlate it with the clinicopathological parameters and to analyze the histomorphology of cases that harbor the characteristic mutations (c-MET and ROS-1). Materials and Methods: Study group comprised a prospective cases series of 90 cases of adenocarcinoma lung. ROS-1 protein expression was determined by immunohistochemistry using the D4D6 rabbit monoclonal antibody (Cell Signaling, Danvers, MA) and c-MET protein expressed was analyzed using the SP-44 clone (Ventana Medical Systems). Results: c-MET protein expression was identified in 33.33% cases (n = 30/90) with statistically significant thyroid transcription factor-1 (TTF-1) positivity. ROS-1 protein expression was detected in 3.33% cases (n-3/90), in biopsies from the respiratory tree with TTF-1 expression. Conclusion: This is the first study from the Indian subcontinent to identify the frequency of ROS-1 re-arrangements and MET amplification in the Indian population. The availability of targeted therapy that has a significant impact on survival makes it essential to detect these less frequent mutations.

Posttransplant epithelioid inflammatory myofibroblastic sarcoma: A case report

Epithelioid inflammatory myofibroblastic sarcoma (EIMS) is a rare entity and a novel variant of inflammatory myofibroblastic tumor (IMT), usually seen in children and nonsmoking young adults. Their occurrence in a posttransplant setting is still rare. These tumors are characterized by prominent epithelioid morphology, large histiocytoid “Reed Sternberg”-like cell, unique pattern of ALK immuno-reactivity, and aggressive clinical behavior. Their etiology and metastatic potential is controversial. In a post-transplant setting, many factors such as trauma, infections with EBV, HIV, Hepatitis C, mycobacteria, fungus, and chemotherapy-induced immunosuppression have been implicated in their etiology. We present the case of a 2-year-old female child who developed multiple omental and mesenteric tumor nodules, 8 months post liver transplant for progressive familial intrahepatic cholestasis (PFIC). Following a histopathological diagnosis of “mesenchymal neoplasm of possible malignant nature” on a trucut biopsy and frozen section, tumor debulking was performed. A final histological diagnosis of EMIS was made on the completely resected tumor. The patient remains in remission nearly 7 months after presentation, without any follow-up systemic chemotherapy. IMT after a solid organ transplant is rare, only 5 cases have been reported in the literature until now. Similar phenomenon has also been noted with hematopoietic stem cell transplant. However, to our knowledge, this case of EMIS in a post liver transplant patient is first of its kind.

Prevalence of substance use disorders in Punjab: Findings from National Mental Health Survey

Background & objectives: Substance use disorders are a major public health concern in Punjab. However, reliable estimates of prevalence of substance use disorders are not available for the State. The present study reports estimates of prevalence of substance use disorders in Punjab, conducted as part of National Mental Health Survey, India. Methods: Using multistage stratified random cluster sampling, 2895 individuals from 719 households of 60 clusters (from 4 districts of Punjab) were interviewed. Mini International Neuropsychiatric Interview and Fagerstrom nicotine dependence scale were used to assess substance use disorders. Results: The sample comprised almost equal numbers of males and females. Nearly 80 per cent had less than or equal to high school education, and 70 per cent were married. The weighted prevalence of alcohol and other substance use disorders was 7.9 and 2.48 per cent, respectively. The prevalence of tobacco dependence was 5.5 per cent; 35 per cent households had one person with substance use disorder. The prevalence was highest in the productive age group (30-39 yr), urban metro and less educated persons. The prevalence of alcohol and other substance use disorders was much higher in Punjab as compared to other States where survey was done. Tobacco dependence was lowest in Punjab. Majority (87%) of the persons with substance use disorders did not suffer from any other mental disorder. Treatment gap was 80 per cent. Interpretation & conclusions: Punjab has a high burden of substance use disorders. The estimates will help clinicians and policymakers to plan the strategies against the menace of substance use disorders effectively.

Estimation Of Bacoside-A In Bacopa Monnieri Aerial Parts Using Tlc Densitometry

Objective: The objective of the present work was to formulate and evaluate a stable, odour free garlic powder loaded floating matrix tablet for the treatment of peptic ulcers. Methods: A gastro-retentive floating matrix tablet (FMT) formulation of garlic powder (GP) was prepared using various concentrations of hydroxypropyl methylcellulose K4M (HPMC K4 M) and effervescent system (sodium bicarbonate and citric acid in 1:1 % w/w) to achieve desirable floating time (FT), floating lag time (FLT) and drug release. Wet granulation method was selected using ethanol as a binder for preparation of tablet. 32 full factorial designs were used for selection of suitable polymer concentration and effervescent system. Nonenteric film coating was applied to mask GP odour. Results: It was observed that FMT with optimum quantities of HPMC K4M and the effervescent system showed 97 % of drug release in 12 h with FT up to 10 h and minimum FLT of 3 min. There was no significant change in FLT, FT and drug content during the stability study of FMT. Conclusion: A stable, sustained release FMT of GP tablets using HPMC K4M and an effervescent system was successfully prepared. This formulation can overcome problems of taste and odour masking, gastric irritation, and loss of active constituents present in garlic.

Fatal Cryptococcus gattii meningitis with negative cryptococcal antigen test in a HIV-non-infected patient

Cryptococcus gattii predominantly causes central nervous system and pulmonary infection in both immunocompromised and immunocompetent patients with substantial morbidity. We report a case of rapidly fatal meningitis by C. gattii in an HIV–non-infected man with CD4 lymphopenia who tested negative for cryptococcal antigen. This case may serve as an alert to its wider occurrence and less explored risk factors.

Study of Variations in Pattern of Calcaneal Articular Facets in Human Tali in the Population of Rajasthan (India).

Talus (astragalus) is the second largest tarsal bone. It has no muscular or tendinous attachment. It takes part in the formation of various articulations in the form of talocrural , talocalcaneonavicular or subtalar joints. The prior knowledge of the anatomical set of talus and its various articulations holds significance in operating procedures. Knowing anatomy of talus not only helps in delineating underlying pathology but also helps in treatment. Three hundred dry adult tali (150- right and 150-left) were studied. Each talus was examined for the presence of various patterns of articular facets. They were classified into five groups. Type I was found in 39% cases. Type II in 43.7% cases, Type III in 6% cases, Type IV in 5.3% cases and Type V was in 6% cases; type V has two subtypes. Subtype ‘A’ was found in 5% cases & subtype ‘B’ was found in 1% cases. In the present study, highest incidence of type II tali was 43.7 % and type IV had lowest incidence of 5.3%. These variations and their incidences can be used as an anthropological marker for racial and regional differences in unidentified bones. Further, studies on various other population is indicated using larger sample size to make comparative studies more meaningful.

Changing trends of services used as first contact by patients with mental health problems.

Background. In the past, traditional faith healers and practitioners of alternative medicine have often been reported to be the first source of contact for Indian patients with mental health problems. However, over the past few decades, this trend seems to be changing. Method. Using a semi-structured questionnaire, we assessed 200 new patients at a psychiatric outpatient service in a general hospital for the first service contact used by them for their mental health problems. Results. Psychiatrists, non-psychiatric physicians, traditional faith healers and practitioners of alternative medicine were the first service contact for 91 (45.5%), 88 (44%), 16 (8%) and 5 (2.5%) patients, respectively. Patients suffering from severe mental illnesses were more likely to choose a psychiatrist as the first contact, whereas those with neurotic, stress-related and organic mental disorders contacted a non-psychiatric physician. Conclusion. In the current scenario, psychiatrists and nonpsychiatric physicians serve as the first service contact for most patients with mental health problems in India, though traditional faith healers and practitioners of alternative medicine are contacted by a minority.

Pharmacogenomic association study on the role of drug metabolizing, drug transporters and drug target gene polymorphisms in drug-resistant epilepsy in a north Indian population.

BACKGROUND: In epilepsy, in spite of the best possible medications and treatment protocols, approximately one-third of the patients do not respond adequately to anti-epileptic drugs. Such interindividual variations in drug response are believed to result from genetic variations in candidate genes belonging to multiple pathways. MATERIALS AND METHODS: In the present pharmacogenetic analysis, a total of 402 epilepsy patients were enrolled. Of them, 128 were diagnosed as multiple drug-resistant epilepsy and 274 patients were diagnosed as having drug-responsive epilepsy. We selected a total of 10 candidate gene polymorphisms belonging to three major classes, namely drug transporters, drug metabolizers and drug targets. These genetic polymorphism included CYP2C9 c.430C>T (*2 variant), CYP2C9 c.1075 A>C (*3 variant), ABCB1 c.3435C>T, ABCB1c.1236C>T, ABCB1c.2677G>T/A, SCN1A c.3184 A> G, SCN2A c.56G>A (p.R19K), GABRA1c.IVS11 + 15 A>G and GABRG2 c.588C>T. Genotyping was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methods, and each genotype was confirmed via direct DNA sequencing. The relationship between various genetic polymorphisms and responsiveness was examined using binary logistic regression by SPSS statistical analysis software. RESULTS: CYP2C9 c.1075 A>C polymorphism showed a marginal significant difference between drug resistance and drug-responsive patients for the AC genotype (Odds ratio [OR] = 0.57, 95% confidence interval [CI] = 0.32–1.00; P = 0.05). In drug transporter, ABCB1c.2677G>T/A polymorphism, allele A was associated with drug-resistant phenotype in epilepsy patients (P = 0.03, OR = 0.31, 95% CI = 0.10-0.93). Similarly, the variant allele frequency of SCN2A c.56 G>A single nucleotide polymorphism was significantly higher in drug-resistant patients (P = 0.03; OR = 1.62, 95% CI = 1.03, 2.56). We also observed a significant difference at the genotype as well as allele frequencies of GABRA1c.IVS11 + 15 A > G polymorphism in drug-resistant patients for homozygous GG genotype (P = 0.03, OR = 1.84, 95% CI = 1.05–3.23) and G allele (P = 0.02, OR = 1.43, 95% CI = 1.05–1.95). CONCLUSIONS: Our results showed that pharmacogenetic variants have important roles in epilepsy at different levels. It may be noted that multi-factorial diseases like epilepsy are also regulated by various other factors that may also be considered in the future.

Assessment of genetic diversity of Clarias batrachus using RAPD markers in three water bodies of Bhopal.

To assess the extent of genetic diversity within and between three populations of the catfish, Clarias batrachus, an analysis for random amplified polymorphic DNA (RAPD) variations were carried out. Five out of ten random primers produced constant and reproducible pattern of RAPD products. These five primers produced 72 scorable DNA fragments out of which 68 (86.66%) were polymorphic. Populations showed significant differences in their degree of polymorphism. Differences however, were observed in the primers in producing similarities in the populations.
