Background: Traumatic brain injury is a common secondary cause of Benign Paroxysmal Positional Vertigo(BPPV). Objective: To determine the incidence and clinical profile of patients with BPPV in mild and moderate head injury. Materials and Methods: A prospective observational study done in patients admitted with mild and moderate head injury who developed BPPV from January 2020 to March 2020 in a tertiary care hospital of South India. Demographic and clinical parameters were noted and were treated with canalith repositioning procedures. Results: Among 42 patients admitted with mild and moderate head injury, 9(21.4%) were diagnosed with BPPV in the follow up. The male female ratio was 2.5:1. The mean age was 44 ±21.4years.Two wheeler accidents contributed to nearly half of (55.6%) traumatic BPPV. Posterior canal was commonly involved in 7(77.8%) followed by horizontal in 2 (22.2%).The type of head injury was mild in 7 (77.8%) and moderate in 2 (22.2%) in traumatic BPPV patients. 5 (55.6%) patients with BPPV had abnormal findings in neuroimaging. 4 (44.4%) patients developed recurrent BPPV in our cohort. Conclusion: The incidence of traumatic BPPV was 21.4% in our study. Road traffic accidents due to two wheeler accidents were the common mode of head trauma. Posterior canal was commonly involved in three fourth of cases. Recurrence of vertigo was documented in 4 (44.4%).
Aim: Nosocomial infections are of great concern in hospital settings especially in intensive care units. Health care professionals and their medical equipment have long been known to act as vectors of pathogens. This study aims at evaluating the presence of bacterial pathogens on stethoscopes of health care workers and to substantiate the effectiveness of alcohol swabs for decontamination of stethoscopes. Methods: 50 stethoscopes belonging to physicians, residents, interns and nurses were swabbed before and after decontamination with alcohol swab. The health care workers belonged to the medicine, surgery, obstetrics, paediatric wards and the intensive care unit. Results: 36% of the stethoscopes were contaminated. Decontamination with 70% isopropyl alcohol showed a significant decrease in contamination. The predominant organism isolated was Staphylococcus aureus (50%). Conclusion: Nosocomial infections carry a higher level of morbidity and mortality. Most stethoscopes harbour potential pathogens. A change in the attitude of health care workers to disinfect their stethoscopes regularly and in between patients will bring about a break in the chain of transmission of infection. We recommend that disinfection of stethoscope should become an integral part of undergraduate and postgraduate education
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
