"Were-wolf" cutaneous tuberculosis

Lupus vulgaris is a variant of cutaneous tuberculosis. Its more destructive and mutilating clinical forms have become rarer in consonance of a general decline of cutaneous tuberculosis. It is rarely seen now in developed countries due to stringent control measures, improved quality of living and effective therapeutic regimens. Misdiagnosis, neglect, or late diagnosis may result in severe, ulcerative and mutilating "wolf eaten" skin lesions.This paper describes four such cases of "were-wolf" cutaneous tuberculosis. Early diagnosis and treatment is important to prevent much of the disfigurement.     

Dapsone for chronic idiopathic thrombocytopenic purpura in children and adults--a report on 90 patients

Data on 90 patients (55 adults and 35 children) with chronic idiopathic thrombocytopenic purpura (ITP) and a platelet count of <50 x 10(9)/L treated with dapsone at a dose of 1-2 mg/kg/d are presented. A response was observed in 57 (63.3%) patients. The average time for response was 3.5 months (range 1-9) and the average duration of treatment with dapsone was 10.4 months (range 4-14). Overall response rates of 65.7% and 61.8% were observed in children and adults respectively. Side effects requiring discontinuation of therapy were observed in three (2%) patients. These results demonstrate that dapsone is an effective, inexpensive and well-tolerated treatment for chronic ITP, in both children and adults and could be considered for patients who fail steroid therapy.     

How Important is the Tunnel Position in Outcomes Post-ACL Reconstruction: A 3D CT-Based Study

BackgroundDrilling the femoral and tibial tunnels at their anatomical locations are critical for good outcomes and involve seeing the footprints well. We intended to compare two techniques of drilling the tunnels and the patient-reported outcomes and knee stability of patients undergoing single bundle ACL reconstruction using 3D CT to evaluate if the tunnels were anatomical or not.Materials and MethodsSixty single bundle ACL reconstructions were analyzed, 30 each with Technique A and B. Pre-operative and after a minimum 27 month follow-up Lysholm, IKDC, Tegner score, hop test, and Lachman test were noted. 3D CT was done to classify femoral tunnels positions as being well placed, slightly or grossly misplaced and tibial tunnels as optimal or suboptimal and compared.ResultsSixty ACL reconstructions had full follow-up with a mean follow-up of 34 months. There was no significant difference between tunnel positions between the two techniques. Well-placed femoral tunnel had better Lysholm score (62.2 ± 16.2 v/s 48.5 ± 17.2, p 0.002) and IKDC score (62.5 ± 14.3 v/s 52.7 ± 15.1, p 0.012).). Those who had their surgeries within 3 months of their injury had better hop test (4.4 ± 0.9 v/s 3.9 ± 1, p 0.034) and IKDC scores (62.5 ± 15.8 v/s 33.2 ± 13.8, p 0.026) as compared to those that had surgery done after 3 monthsConclusionTibial tunnel positions were optimal in most cases and did not differ between the two techniques. Well-placed femoral tunnels and surgeries done within 3 months of the injury produced best results.     

Non-destructive measurement technique for water content in organic solvents based on a thermal approach

The water content of organic solvents is one of the crucial properties that affect the quality of the products and the efficiency of the manufacturing processes. The established water determination methods such as Karl Fischer titration and gas chromatography require skilled operators, specific reagents, and prolonged measurement time. Thus, they are not suitable for both on-line and in-line applications. In this study, we aim to develop a real-time and low-cost device with reliable accuracy. The proposed device based on a newly developed thermal approach could non-destructively detect the water content in multiple organic solvents at low concentrations with high accuracy and without the use of any specific reagent. Experiments were performed for the determination of water content in organic solvents such as methanol, ethanol, and isopropanol. The results show that the proposed device is feasible for the water content determination in methanol, ethanol, and isopropanol at 0–1% w/w. A Bland–Altman plot to illustrate the differences in measurements between the proposed device and coulometric Karl Fischer titration shows that most of the measurements lie within the limits of agreement where 95% of the differences between the two methods are expected to fall in the range of −0.13% and 0.09%.

Awareness,Beliefs and Perspectives Regarding Weight Retention and Weight Gain among Postpartum Women in India: A Thematic Analysis of Focus Group Discussions and In-Depth Interviews

Background and AimsThe pregnancy weight is usually retained in the form of abdominal fat during the postpartum period. The willingness to lose weight is influenced by knowledge, attitude, beliefs and practices. This study aims to comprehend the awareness, beliefs and perspectives of postpartum women regarding their perceived factors, barriers and facilitators associated with post-pregnancy weight status.MethodsOverweight and obese postpartum women aged between 20 and 40 years and had delivered an infant in the last 2 years were recruited via convenience and purposive sampling techniques. The final sample comprised 27 participants with a mean age of 29.96 ± 4.50 years. Four focus group discussions and eight in-depth interviews carried out were audio-recorded and transcribed verbatim. Codes, sub-themes and themes were generated using Atlas.ti 9 software.ResultsMajor themes identified were perceived factors causing postpartum weight retention/weight gain including social and cultural beliefs related to diet and exercise specifically associated with this period, perceived motivators and deterrents of weight loss including eagerness to lose weight and perceived facilitators and barriers to weight loss including intrinsic and extrinsic factors such as time, energy, evidence-based knowledge about diet and physical activity, family support and obligation to family’s advice.ConclusionThe unique challenges and barriers associated with postpartum weight loss efforts should be taken into consideration by healthcare professionals and public health policy-makers to design strategies specific to postpartum women.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13224-022-01644-9.     

Right ventricular outflow tract obstruction caused by a right coronary cusp prolapse: An unusual finding

Patients with large sub-pulmonic ventricular septal defect (VSD) present early as a results of their complications. Some present late, due to the restriction of VSD by the right coronary cusp (RCC) due to its prolapse. In this report, we present a rare case of sub-pulmonic VSD in a 33-year-old man who developed a sub-pulmonic stenosis due to the prolapse of the RCC into the right ventricular outflow tract.
