So, infections due to Corynebacterium species may remain undiagnosed or misdiagnosed. The aim of our study was to focus on non-diphtheriae Corynebacterium as causative organisms in breast infections using scientific logic and technology of Matrix Assisted Laser Desorption Ionisation Time of Flight Mass Spectrometry (MALDITOF MS) to categorize the isolates upto species level. The clinical correlation and response to management especially targeted antimicrobials was also recorded. Methods: All the consecutive pus/tissue samples from Breast abscess received during study period were processed as per the standard guidelines. The identification of the isolate was done by automated methods. The cytopathological/histopathological and clinical details of the patients with infection due to Corynebacterium sp. were recorded and analyzed. Results: Out of 52 non-duplicate samp...

This study was conducted in 15 Indian tertiary care centres during a two year period from January 2008 to December 2009 to determine the prevalence of MRSA and susceptibility pattern of S. aureus isolates in India. Methods: All S. aureus isolates obtained during the study period in the participating centres were included in the study. Each centre compiled their data in a predefined template which included data of the antimicrobial susceptibility pattern, location of the patient and specimen type. The data in the submitted templates were collated and analysed. Results: A total of 26310 isolates were included in the study. The overall prevalence of methicillin resistance during the study period was 41 per cent. Isolation rates for MRSA from outpatients, ward inpatients and ICU were 28, 42 and 43 per cent, respectively in 2008 and...

Research paper thumbnail of A Retrospective Observational Study to Determine the Early Predictors of In-hospital Mortality at Admission with COVID-19

The objective of this study is to identify the clinical and laboratory variables as predictors of in-hospital death at the time of admission in a tertiary care hospital in India. Materials and methods: Demographic profile, clinical, and laboratory variables of 425 patients admitted from April to June 2020 with symptoms and laboratory-confirmed diagnosis through real-time polymerase chain reaction (RT-PCR) were studied. Descriptive statistics, an association of these variables, logistic regression, and CART models were developed to identify early predictors of in-hospital death. Results: Twenty-two patients (5.17%) had expired in course of their hospital stay. The median age [interquartile range (IQR)] of the patients admitted was 49 years (21-77 years). Gender distribution was male-73.38% (mortality rate 5.83%) and female-26.62% (mortality rate 3.34%). The study shows higher association for age (>47 years) [odds ratio (OR) 4.52], male gender (OR 1.78), shortness of breath (OR 2.02), oxygen saturation <93% (OR 9.32), respiratory rate >24 (OR 5.31), comorbidities like diabetes (OR 2.70), hypertension (OR 2.12), and coronary artery disease (OR 3.18) toward overall mortality. The significant associations in laboratory variables include lymphopenia (<12%) (OR 8.74), C-reactive protein (CRP) (OR 1.99), ferritin (OR 3.18), and lactate dehydrogenase (LDH) (OR 3.37). Using this statistically significant 16 clinical and laboratory variables, the logistic regression model had an area under receiver operating characteristic (ROC) curve of 0.86 (train) and 0.75 (test). Conclusion: Age above 47 years, associated with comorbidities like hypertension and diabetes, with oxygen saturation below 93%, tachycardia, and deranged laboratory variables like lymphopenia and raised CRP, LDH, and ferritin are important predictors of in-hospital mortality.

We report two cases of fatal pulmonary infection caused by Nocardia otitidiscaviarum in elderly patients. Methodology: Case 1: A 70-year old woman presented with fever and cough with expectoration for a month. On physical examination, she had tachypnea and inspiratory crepitations in bilateral basal regions. Case 2: A 74-year old man presented with productive cough with foul smelling expectoration, fever and shortness of breath for one week. On examination, he had tachypnea, bilateral wheezing and inspiratory crepitations. In both cases, sputum was sent to microbiology laboratory. On direct microscopy Gram-positive, finely branching filaments were observed which were acid fast with 1% sulphuric acid. Chalky white opaque wrinkled colonies with musty basement type odour were seen on blood agar. Both patients were treated empirically wit...

(9 patients). At the time of diagnosis, only six patients were on an antifungal with mold activity. Eight patients died during hospitalization. The distribution of cases over time was compared with weather data for Colorado. A cluster of cases occurred in 2013 (6 cases) and in 2017 (8 cases). A majority of cases were diagnosed during the summer and fall months with July being the month with the most number of cases. There were higher levels of precipitation that occurred prior to or during the cluster of cases. Conclusion. Cases of mucormycosis at UCH were associated with DM, hematologic malignancy/HSCT, use of immunosuppressive therapy, and invasive procedures. The increase of cases seen 2013 and 2017 occurred in the summer and fall months after higher levels of precipitation were observed in Colorado. Providers at UCH may consider modifying antifungal prophylaxis to include mold coverage in patients with >2 risk factors for mucormycosis who are admitted during the summer and fall. Disclosures. M.

Cross-sectional study. Thirteen private schools in urban Faridabad, Haryana. 961 school children aged 5-10 years. Ultrasound testing was done, and 215 with fatty liver on ultrasound underwent further clinical, biochemical and virological testing. Prevalence of fatty liver on ultrasound, and NAFLD and its association with biochemical abnormalities and demographic risk factors. On ultrasound, 215 (22.4%) children had fatty liver; 18.9% in normal-weight and 45.6% in overweight category. Presence and severity of fatty liver disease increased with body mass index (BMI) and age. Among the children with NAFLD, elevated SGOT and SGPT was observed in 21.5% and 10.4% children, respectively. Liver enzyme derangement was significantly higher in overweight children (27% vs 19.4% in normal-weight) and severity of fatty liver (28% vs 20% in mild fatty ...

These organisms are reported to be associated with health benefits and their significance as a pathogen is not much reported. We are reporting two cases of mixed pyogenic infections due to Bifidobacterium sp. In the first patient, the infection mimicked tubercular bone infection. The second patient was a case of hydronephrosis with double J (DJ) stent blockage. In both cases, Bifidobacterium sp. was isolated in combination with Escherichia coli from the evacuated pus samples. The factors which contributed significantly for detecting Bifidobacterium sp. were gram stain examination, use of rapid and automatic anaerobic cultivation system (Anoxomat, MART Microbiology B.V., The Netherlands), and quick identification by MALDI-TOF (Matrix-Assisted Laser Desorption-Time-of-Flight) Mass Spectrometry (Biomerieux, France). Both strains were found to be resistant to metronidazole and both patien...
