Glomus tympanicum removal using transcanal endoscopic assisted surgery: An experience with six cases.

Objective: To evaluate an endoscopic approach in the management of glomus tumor, and also to investigate and evaluate its appropriateness and feasibility. Methods: Glomus tumors, also known as paragangliomas, are benign primary tumors of the middle ear. The advent of endoscopic ear surgery has provided new dimensions to the management of this highly vascular tumor. Retrospective analysis of six patients of glomus tympanicum, operated between July 2014 and June 2019, with modified Fisch classification Type A and B1, who were managed by a retroauricular transcanal endoscopic approach. Preoperative and postoperative analysis was done for these patients. Results: The chief complaint was pulsatile tinnitus, which disappeared in five cases and reduced in severity in one of them. Hearing was improved with reduction in air-bone gap in all the cases. No major complications or recurrence were observed in any of the patients after 12 months of follow-up. Conclusion: This endoscopic approach serves as a safe and reliable technique for tumor removal. It thus provides postoperative comfort for most of the patients.

COVID-19 associated multisystemic mucormycosis from India: a multicentric retrospective study on clinical profile, predisposing factors, cumulative mortality and factors affecting outcome.

PURPOSE: The clinical course of COVID-19 has been complicated by secondary infections, including bacterial and fungal infections. The rapid rise in the incidence of invasive mucormycosis in these patients is very much concerning. COVID-19-associated mucormycosis was detected in huge numbers during the second wave of the COVID-19 pandemic in India, with several predisposing factors indicated in its pathogenesis. This study aimed to evaluate the epidemiology, predisposing factor, cumulative mortality and factors affecting outcomes among the coronavirus disease COVID-19-associated mucormycosis (CAM). METHODS: A multicenter retrospective study across three tertiary health care centers in Southern part of India was conducted during April-June 2021. RESULTS: Among the 217 cases of CAM, mucormycosis affecting the nasal sinuses was the commonest, affecting 95 (44%) of the patients, orbital extension seen in 84 (38%), pulmonary (n = 25, 12%), gastrointestinal (n = 6, 3%), isolated cerebral (n = 2) and disseminated mucormycosis (n = 2). Diabetes mellitus, high-dose systemic steroids were the most common underlying disease among CAM patients. The mucormycosis-associated case-fatality at 6 weeks was 14%, cerebral or GI or disseminated mucormycosis had 9 times higher risk of death compared to other locations. Extensive surgical debridement along with sequential antifungal drug treatment improved the survival in mucormycosis patients. CONCLUSION: Judicious and appropriate management of the predisposing factor and factors affecting mortality associated with CAM with multi-disciplinary approach and timely surgical and medical management can be much helpful in achieving a successful outcome.

Assessment of healthcare worker's hand hygiene and infection prevention practices of their personal belongings in a healthcare setting: a survey in pre COVID-19 era and literature review on standard disinfection practices.

BACKGROUND: Healthcare workers' (HCW) hands and personnel belongings are vehicles of transmission of nosocomial infections. Knowledge, attitude, and practice of hand hygiene have been extensively studied suggesting adequate knowledge but poor compliance. Similar data on aprons, mobile phone and stethoscope disinfection practices are lacking. This becomes an extensively important topic of discussion in current COVID-19 pandemic where inadequacy in hygiene practices is devastating. AIM: To study the knowledge, attitude, and infection prevention practices of HCWs aprons, electronic devices, stethoscopes, and hands. METHODS: A cross sectional questionnaire-based survey was conducted among HCWs of Medicine ward and ICU. RESULTS: Sixty-six HCWs responded to the survey. Awareness that hands, aprons, mobile phones, stethoscopes could cause cross transmission and knowledge of correct practices was present in majority of the respondents. Hand hygiene was performed by 65.2% of the respondents before touching a patient and 54.5% after touching the patient surroundings while 13.6% performed only when it was visibly soiled. Mobile phones and stethoscopes were disinfected by 13.6 and 30.3% of the respondents after each patient encounter, respectively. Aprons were washed after using them at a stretch for a median duration of 5 days (1-30 days). Forgetfulness, lack of reinforcement, lack of time, inadequate awareness on standard disinfection practices and fear of damaging electronic devices from disinfectants use were reasons for poor compliance. CONCLUSIONS: There is an urgent need to spread awareness and formulate standard guidelines on disinfection practices especially for mobile phones, stethoscopes, and aprons in addition to reinforcing hand hygiene practices.

Fungal carriage on healthcare workers' hands, clothing, stethoscopes and electronic devices during routine patient care: a study from a tertiary care center.

BACKGROUND: Invasive fungal infections are a constant threat to immunocompromised and critically ill patients. Healthcare workers caring for such patients act as conduits of transmission through their contaminated hands and belongings causing nosocomial infections. Although bacterial contamination of healthcare workers is known, our knowledge about fungal carriage is sparse. Among the fungi, candida species colonization of hands of healthcare workers is known however it would be interesting to know the type of fungal carriage on their inanimate belongings. AIM: To study the prevalence and type of fungal carriage on healthcare workers hands, aprons/hospital scrubs, electronic devices, and stethoscopes. METHODS: Healthcare workers working in Medicine ward and ICU during November and December 2019 were sampled. Hand washes were collected in Brain Heart Infusion (BHI) broth with gentamycin. Direct impression smears on blood agar were taken from aprons/hospital scrubs. Electronic devices and stethoscopes were sampled using moist cotton swabs. Subculture and plating was done on Sabarouds Dextrose Agar (SDA). Yeasts were identified using Matrix Assisted Laser Desorption Ionisation Time of Flight (MALDI TOF) and moulds were identified using microscopy. FINDINGS: Out of 60 health care workers, 20 (33.3%) had fungal carriage. Aprons/hospital scrubs and hands were contaminated in 17 (28.3%) and 3 (5%) respectively. Aprons/hospital scrubs mainly constituted moulds belonging to species of Aspergillus. Hands were contaminated with Candida tropicalis, Candida parapsilosis and Candida auris. Electronic devices and stethoscopes had no fungal contamination. CONCLUSIONS: Active fungal surveillance provides prevalent carriage rates and serve as a feedback to improve our disinfection and hand hygiene practices. It also aids in identification of potential source of hospital outbreaks.

Management of dengue with co-infections: an updated narrative review.

Dengue is a life-threatening mosquito borne viral disease. We are still in the era of supportive treatment where morbidity and mortality are a major concern. Dengue infection in presence of other co-infections makes this scenario rather worse. Timely recognition and raising alarm to be intensive is the need of the hour for primary care physicians practicing in the community and indoors. This review provides a comprehensive knowledge about the recent trends of coinfection in dengue as well as their management consideration which will be particularly helpful for physicians practicing in rural and remote areas of India.

Evolution of olfactory and gustatory dysfunctions in COVID-19 patients in India.

PURPOSE: The ongoing coronavirus disease 19 (COVID-19) pandemic is spreading at an alarming rate across the globe. Sudden onset loss of smell and/or taste has been increasingly reported as a symptom of COVID-19. However, prevalence of these symptoms, and its severity varies widely between studies, with little data on its duration and recovery rate. Since this significantly impacts the quality of life of patients, there is a need for a study to provide insight into the loss of smell or taste in terms of its correlation with other upper respiratory tract symptoms, natural history and resolution rates. METHODS: This cross-sectional study included 718 mild to moderately symptomatic adult patients (≥ 18 years), admitted consecutively to Kalinga Institute of Medical Sciences (KIMS), Odisha, India between June 25 and July 24, 2020, who tested positive for SARS-CoV-2 by polymerase chain reaction on nasopharyngeal and throat swabs. Prevalence, severity, duration and factors associated with altered smell or taste sensation, and their follow-up were recorded. RESULTS: Of the 718 patients included in the study at baseline [563 (78%) men; median age 34 years], 101 (14%) patients experienced either altered smell or taste, with 52 (7%) experiencing both altered smell and taste. Seventy-seven (10.7%) patients had altered smell and 76 patients had altered taste (10.5%). Of these, 71 (92%) and 73 (96%) regained their sense of smell and taste, respectively, by 14 days after their swab tested positive. Presence of fever (OR = 5.4, 95% CI = 2.7-10.6, p < 0.001), cough (OR = 2.3, 95% CI = 1.2-4.2, p = 0.009) and nasal obstruction (OR = 3.1, 95% CI = 1.4-6.7, p = 0.006) were independently associated with increased likelihood of experiencing both altered taste and smell in multivariable models. CONCLUSION: The prevalence of altered smell and taste in Indians was much lower compared to Europeans and similar to East Asians. Majority regained these senses by 2 weeks. Identification of these symptoms can help in early detection of the disease in suspected individuals.

Nosocomial pneumonia: Search for an empiric and effective antibiotic regimen in high burden tertiary care centre.

The clinical practice guidelines on nosocomial pneumonia recommends an empirical regimen that would work in 95% of the patients based on the local antibiogram. The aim of the study was development of an antibiogram for guiding empiric therapy in settings with high prevalence of multi-drug resistant organisms. A retrospective review of electronic health records (e-hospital portal) was done to analyze all respiratory isolates from patients admitted in medical wards and intensive care unit between May 2016 and May 2017. The samples included brocho-alveolar lavage (BAL), mini broncho-alveolar lavage (mini-BAL) and endotracheal aspirate. The sensitivity pattern (combined and individual) of all bacterial isolates were analysed for commonly used antibiotics and their combinations. Out of the 269 isolates, the most common organisms were Pseudomonas aeruginosa (125, 46%), Acinetobacter baumanni (74, 27%) and Klebsiella pneumoniae (50, 19%). Cefoperazone-sulbactam (43%) had the best sensitivity pattern overall. Cefoperazone-sulbactam plus amikacin (56%) was the combination with the best combined sensitivity overall. There is a high prevalence of resistance in the commonly implicated organisms to the available antibiotics. There is an urgent need for implementation of effective anti-microbial stewardship programmes and development of newer antimicrobials.

Under-explored Dimensions of Anti-microbial Stewardship in India.

Antimicrobial resistance accounts for the greatest threat to the health system. The most appropriate path to mitigate this menace is a collaborative, multidisciplinary approach combining antimicrobial stewardship with infection prevention. Sustainable efforts to overcome this global problem would require awareness, learning and coordination at various levels in the health system. Government policies, national guidelines, collaborative functioning in research, online training modules, and media have an important role in combating the threat. We recommend a multipronged approach involving the infection control specialist, as well as various cadres of health-care providers, including pharmacists, the nurses and community-level health workers. We also recommend that all health-care professionals prescribing antibiotics take responsibility and understand the adverse consequences of inappropriate and suboptimal antibiotic usage. Certain countries in the world have already in place the antimicrobial stewardship programme with multi-disciplinary approach. India needs to have a strengthened anti-microbial stewardship programme involving all cadres of health-care providers.

Association of Three H - Hookworm, Hemosuccus Pancreaticus, and Hypertension (Portal) in a Patient with Melena.

Hookworm infestations, endemic in India, are a common cause of iron deficiency anemia. Hemosuccus pancreaticus, a rare clinical condition, is due to passage of blood into the pancreatic duct possibly through a route between an aneurysm of an artery close to the pancreas and/or pancreatic duct, leading to gastrointestinal (GI) bleeding. Portal hypertensive upper GI bleed is also known since long. We report a case of a 38-year-old male with a history of alcoholism who was being investigated for GI bleeding who had concomitant hookworm infestation, hemosuccus pancreaticus as well as portal hypertension. To the best of our knowledge, this is the first report of common occurrence of hemosuccus pancreaticus and portal hypertension with hookworm infection. This case signifies the importance of infectious causes of GI bleeding to be considered even in cases where anatomic malformations or pathophysiological alterations are predominant.

Splenic Abscess Caused by Salmonella Typhi and Co-Infection with Leptospira.

Splenic abscesses caused by Salmonella typhi are a very rare complication of typhoid fever in this era of use of specific antibiotics. Co-infection with Leptospira in such a patient is even rarer. Clinical diagnosis of splenic abscess caused by Salmonella is difficult owing to its rarity, being insidious in onset and having nonspecific clinical presentation. Splenic abscesses are potentially fatal complication of typhoid fever. In most of these patients, hemoglobinopathies or some other underlying immunocompromised state is usually present. We report a case of splenic abscess, caused by Salmonella typhi, and co-infection with Leptospira in a previously healthy young male.
