A study to evaluate the outcomes of traditional lecture classes and self-directed learning sessions among the first MBBS students in the department of physiology

Background: To become lifelong learners, it is essential for medical students to develop self-directed learning (SDL) skills from early medical schools. Aim and Objective: The present study was conducted to compare the outcome of traditional lecture classes (LCs) and SDL sessions among the first MBBS students in the department of physiology. Materials and Methods: This pilot study was conducted over a period of 1 year in the department of physiology among the first MBBS students to compare the outcome of traditional LCs with SDL sessions. The first 12 traditional LCs were conducted among Group A (roll no. 1–100) and the first 12 SDL sessions were conducted among Group B (roll no. 101–200). For the rest 13 traditional LCs and SDL sessions, crossover of two groups was done, that is, traditional LCs were conducted among Group B and SDL sessions were conducted among Group A. Results: Students performed significantly better in the 3rd, 7th, 10th, 11th, 12th, 13th, 15th, 18th, 19th, 21st, and 22nd SDL sessions as compared to LCs in post-test sessions. Students performed significantly better in the 4th, 6th, 8th, 16th, 23rd, 24th, and 25th LCs as compared to SDL sessions in posttests. Students performed significantly better in post-test sessions as compared to pre-test sessions. Students were highly satisfied with the program (as per evaluation done by Kirkpatrick model: Level 1). Conclusions: The students were highly satisfied with the teaching-learning program implemented by the department of physiology and their performance was better following SDL sessions as compared to traditional LCs.

A study of perceived stress level and sleep quality among physicians in a hospital of West Bengal, during the second wave of the present coronavirus disease-19 pandemic

Background: Stressful life events may lead to insomnia, a very common sleep disorder. Aim and Objectives: The aim of the study was to study the correlation of perceived stress levels and sleep quality among physicians during the coronavirus disease-19 Pandemic. Materials and Methods: Physicians working in Burdwan Medical College were selected as a study group and age, sex-matched controls were selected from other non-medical workers. This online survey was conducted using Google Forms. The form was shared with participants using emails and WhatsApp. In the first section of the form the importance of the study was explained and informed consent was taken from the participants. In the second part of the form, subjects were asked to fill up demographic details and relevant history; in the third part, participants were asked to fill up two scales: Perceived Stress Scale (PSS) and Pittsburgh Sleep Quality Index (PSQI). Results: 128 doctors and 114 other staff participated in the present study. Doctors had significantly higher PSS and PSQI levels as compared to the other group. Doctors’ PSQI: Mean ± SD = 7.59 ± 4.37 and other staff PSQI: Mean ± SD = 5.77 ± 2.75; P: 0.00013**. Doctors’ PSS: 18.43 ± 4.04 and other staff PSS: 15.14 ± 1.7; P < 0.0001**. PSS and PSQI levels were positively correlated in both groups with r values of 0.975 for Doctors and 0.544 for other staff, respectively. Conclusions: Doctors were found to have higher PSS and PSQI levels as compared to the control group. PSS levels were found to be positively correlated with PSQI levels and more so among doctors.

Antimicrobial resistance: Causes and impact on public health in developed and developing countries

Antibiotic-resistance (AR) has become an alarming issue, posing threats to public health in terms of mortality and economic loss. The drivers of AR include environmental contamination from varied sources, ultimately making its way into our drinking water and food. Other factors include reckless use of antibiotics by the uneducated health workers, unhygienic situation of the hospitals, overconsumption and careless discharge of medicines by the general populace, injudicious use of antibiotics in the livestock, and indiscriminate disposal of untreated pharmaceutical wastes into the municipal water have caused several health hazards, such as “AR in infants,” respiratory disorders, and cancer. Furthermore, the sewage treatment process itself augments the antimicrobial resistance crisis. Hence, it is an alarming issue which must be taken care at the global level as well as the national level.

Snakebite and its management in rural West Bengal: The unspoken truth

Background: Snakebite is a common medical emergency in tropical India where agriculture is a major source of earning livelihood. Snakebite has a significant impact on human health and economy. The situation worsens when the majority of snakebite victims adopt harmful practices such as application of tourniquets due to prevalent myths and misconceptions. Objectives: The objective of the study was to study the socio-demographic profile of the study population, to estimate the prevalence of snakebite in the study area, and to assess the knowledge and treatment seeking behavior of the study population regarding snakebite and its management. Materials and Methods: A total of 135 households of Muchisa village of West Bengal were selected by consecutive sampling and one adult member of the household was interviewed with a pre-designed schedule. Results: Majority of the study population were in the age group of 30–60 years (69.5%), females (52.6%), and Hindu (74.8%). Nearly 59.1% (100) of the population were educated up to primary level. Nearly 15.56% of the study population in our study gave a history of snakebite. Nearly 81.1% of study population correctly differentiated between poisonous and nonpoisonous snakebites based on signs and symptoms of the victim. When asked about why snakebite, the villagers said that snakebite when they were touched (57.04%) or hit (33.33%). About 57.78% of the population believed that snakebite can be managed by traditional faith healers (Ojha). The majority preferred tying a tourniquet/similar material above the bite mark. Conclusion: It is essential to communicate about the appropriate management of a snakebite victim to the communities at risk of snakebite.

Percutaneous epididymal sperm aspiration followed by intrauterine insemination--a new approach to achieve a pregnancy in infertility due to obstructive azoospermia.

Standard approach towards treatment of obstructive azoospermia whether congenital or acquired is mostly microsurgical epididymal sperm aspiration (MESA) and to some extent percutaneous epididymal sperm aspiration (PESA) both being followed by intracytoplasmic sperm injection (ICSI). However in the present series for sperm retrieval in case of obstructive azoospermia the author conducted a series of 55 cases of PESA along with only 4 cases of MESA. The epididymal sperm aspiration (ESA) was followed by intrauterine insemination (IUI) (whenever required quantity of motile sperm was collected) in place of ICSI with full consent of the couples. With the help of this ESA-IUI programme it was possible to achieve reasonable success rate viz, 20% pregnancy rate (PR) per cycle for PESA-IUI and 14.28% for MESA-IUI.

Aluminium related changes in brain histology: protection by calcium and nifedipine.

Aluminium (Al; 50 mg AlCl3/kg body wt/day) treatment caused a marked change in histological picture of normal brain as indicated by an increased number of vacuolated spaces. These changes returned to normal partially by simultaneous treatment with nifedipine (0.7 mg/kg body wt/day) and completely by similar treatment with 50 ppm calcium (CaCl2; 12.5 mg/kg body wt./day). Neither nifedipine nor calcium treatment alone altered the normal histological condition. The histological changes could not be correlated with the decrease in calcineurin activities in brain as nifedipine decreases calcineurin activity without any histological changes. Hence the histological changes may be considered as specific for Al and not due to a general decrease in calcineurin activity.

Effect of high arsenic content in drinking water on rat brain.

The permissible limit of arsenic content in drinking water is 0.05 ppm, whereas, in many parts of West Bengal the arsenic level in drinking water is 0.1 ppm, frequently 0.3 ppm and even 3.0 ppm, though rarely. In order to assess possible risk to brain function by drinking such water, rats were given arsenic mixed in drinking water at the above four concentrations for 40 days. There was increased lipid peroxidation at all doses of arsenic, including the 'permissible limit', decrease in glutathione level, superoxide dismutase and glutathione reductase activities, indicating the free-radical-mediated degeneration of brain.

Effect of ascorbic acid on in vitro synthesis of testosterone in rat testis.

Effect of ascorbic acid on testicular steroid dehydrogenase activity and testosterone concentration, using in vitro preparation of rat testis, was studied. A significant stimulation of enzyme activity and rise in testosterone content were observed.

The effect of aspirin on neurodeficit and platelet aggregability in acute ischemic cerebral strokes.

We examined the role of aspirin in modifying platelet aggregability (PA) and neurodeficit (ND) in patients presenting within 48 hours of acute ischemic cerebral strokes of the carotid territory. 28 adult patients were studied at baseline and after 7 days of treatment with a single daily dose of aspirin 325mg (group A, n = 12) and 160 mg (Group B, n = 16). We also evaluated the neurologic outcome at the beginning and at the end of 7 days using a scoring system. There was no significant difference in the ND scores and in vitro PA between these two groups. PA, as measured in vitro, does not appear to have any significant role as a predictor of neurologic outcome in acute ischemic strokes. The change in ND scores of patients with ischemic cerebral strokes treated acutely with aspirin was not significant upto first 7 days therapy.

Histopathological and immunological studies in a cohort of balanitis xerotica obliterans.

Balanitis xerotica obliterans consisting of 52 cases had been studied in the present series. This disease entity is an insidious sclerosing disease of unknown aetiology, affecting mainly the skin and mucous membrane of glans, prepuce and sometimes the fossa navicularis urethrae or even terminal urethra. Atrophic white patches on external genitalia and obstructive uropathy are two common presenting features. It has been classified as local form of lichen sclerosus et atrophicus. Poor local hygiene, circumcision and association of auto-immune diseases like vitiligo are responsible as suggested in this study. Routine tests detected associated cystitis in 8 cases, haematuria in 4 cases, non-reactive VDRL in all cases and impaired glucose tolerance in 5 cases. Immunoglobulin profile (39 cases) showed altered pattern, suggesting some chronic antigenic stimulation. Out of 33 cases where biopsy done, histologically proved typical balanitis xerotica obliterans was found in 19 cases. Malignant change was noted in one case only. Circumcision and dilatation offered temporary relief.

Influence of admission weight on neonatal mortality amongst hospitalised neonates in Calcutta.

The study was conducted on 785 neonates aged up to 28 days to evaluate the influence of admission weight on mortality. It was observed that there were 200 (25.5%) cases of septicaemia, 134(17.1%) of diarrhoea, 120(15.3%) each of prematurity related conditions and neonatal jaundice, 117(14.9%) of respiratory diseases and 94 (11.9%) cases of convulsion. There were total 182(23.18%) deaths comprising 70(38.5%) from prematurity related conditions, 40(22%) from diarrhoea, 35(19.2%) from respiratory diseases, 26(14.3%) from septicaemia, 8(4.4%) from neonatal jaundice and 3(1.6%) deaths from convulsion. The incidence of deaths among neonates weighing less than 2500 g on admission was 59.2% in diarrhoeal diseases, 53.4% in respiratory diseases and 44.6% in other conditions compared to those of 10%, 8.2% and 7.1% respectively in neonates having admission weight more than 2500 g. The findings are statistically significant. The results of the study indicate that low admission weight should be considered as a predictor of mortality among neonates.
