Bacterial Assessment of Stethoscopes Used by Healthcare Workers at a Tertiary Care Government Hospital in Bharatpur, Nepal.

The transmission of healthcare-associated infections (HCAIs) in healthcare settings is a serious challenge in the medical fraternity. Medical devices, such as stethoscopes used by healthcare workers (HCWs), are likely to harbor a considerable number of pathogenic microbes, which may result in the transmission of HCAIs. This study sought to investigate bacterial contamination of stethoscopes used by HCWs at Bharatpur Hospital, Nepal. During the study period of 3 months from December 2019 to February 2020, a total of 87 stethoscopes were examined; bacterial pathogens were isolated and identified by culture and biochemical tests, and their susceptibilities against different antibiotics were determined using standard protocols of the Clinical and Laboratory Standards Institute (CLSI). The disc diffusion method was used primarily to screen for extended-spectrum beta-lactamase (ESBL)- and metallo-beta-lactamase (MBL)-producing isolates, followed by their confirmation using cephalosporin/clavulanate combination discs and the disc potentiation methods, respectively. In addition, molecular detection of blaCTX-M and blaVIM genes was performed using conventional polymerase chain reaction (PCR). Of the 87 stethoscopes examined, more than a quarter (28.7%) were colonized with different pathogenic bacteria. Bacterial contamination of stethoscopes was found to be significantly associated with various factors, such as disinfecting routine, method of disinfection, and department of the hospital (p < 0.05). A higher rate of bacterial contamination was observed on the diaphragm of the stethoscope (12.64%) and among HCWs who overlooked hand hygiene practices (45.45%). The prevalence of methicillin-resistant S. aureus (MRSA) was 44.44%, and approximately half of the Gram-negative isolates (47%) were multidrug resistant (MDR). Imipenem (81.25%) and chloramphenicol (83.33%) were found to be the most effective antibiotics for Gram-negative and Gram-positive bacteria, respectively. Phenotypic screening showed that 43.75% of isolates were ESBL producers, and 18.75% were MBL producers, but blaCTX-M and blaVIM genes were detected in only 31.25% and 6.25% of isolates, respectively. The results of the study call for effective stethoscope disinfection practices along with the judicious use of antibiotics by HCWs in order to minimize cross-contamination, emergence of resistance, and spread of nosocomial infections in clinical settings.

Euglycemic diabetic ketoacidosis in a patient with acute stroke taking sodium glucose co-transporter 2 inhibitor.

Introduction: Diabetic Ketoacidosis is characterized by a triad of metabolic acidosis, hyperglycemia, and ketonemia. It is a medical emergency that needs urgent and aggressive management. In some cases, the blood glucose level may be relatively normal. Such a condition is known as Euglycemic Diabetic Ketoacidosis. Case presentation: We present a case of Euglycemic Diabetic Ketoacidosis, who was initially brought to the emergency room with the features of acute stroke. There was a diagnostic dilemma among the treating physicians due to his relatively normal blood glucose levels while he developed ketoacidosis. Discussion: Presentation of the patients includes similar to DKA such as nausea, vomiting, malaise, fatigue, and Kussmaul's respiration. The diabetic patients under sodium glucose co-transporter-2 inhibitor therapy may develop it under the setting of different precipitating factors like infection, trauma/surgery, strenuous physical exercise, fasting, alcohol intake and acute vascular events. Conclusion: Euglycemic DKA is a rare condition and its diagnosis is a challenging task. So, we should always consider it as a differential whenever any diabetic patient shows with increased anion gap metabolic acidosis with or without typical symptoms and signs. Also, we need to be aware to discontinue of SGLT-2 medication during the time of infection, surgery, severe trauma, acute illness and dehydration in the diabetic patients.

Perception Regarding Tooth Carving Using wax Block among the Dental Practitioners.

BACKGROUND: The various pedagogical methods applied for teaching dental anatomy to dental students includes lectures, analysis of extracted natural teeth and carving of wax blocks to accurately replicate the morphology of teeth. The thorough knowledge of dental morphology is indispensable for a successful dental practice. This study was thus aimed to assess the perceived relevance of tooth carving using wax block among the dental practitioners. METHODS: A cross-sectional study was designed with the objective of involving dental practitioners working in Kathmandu. Self-administered questionnaires were used for the data collection. The results were later analyzed for descriptive statistics using the Statistical Package for the Social Sciences (SPSS) 16 software. RESULTS: About 232 (98.3%) participants practiced tooth carving using wax block to study dental anatomy. More than 96% of the participants agreed that tooth carving exercises have helped them better understand tooth morphology and more than 85% feel that their manual dexterity was developed by these exercises. A total of 223 (94.5%) were of the opinion that tooth carving should be continued in the BDS preclinical curriculum. CONCLUSIONS: The dental wax carving is an effective pedagogical strategy to develop manual dexterity of dental students by recreating tooth morphological features using a wax block, thereby achieving the mandatory psychomotor skills.
