Haemophilus are fastidious Gram negative bacilli, which require factor X (hemin), factor V (NAD), or both for their growth. Haemophilus influenzae is the type species, and is considered to be the most pathogenic. They are associated with many invasive infections including meningitis, epiglottitis, pneumonia, and otitis media. Serotype b is most commonly associated with infections. Haemophilus species isolated from patients in a tertiary care centre in South India were studied. Identification, serotyping and biotyping were done and antibiotic susceptibility test was performed. The incidence of H. influenzae infections in our study was 65.3 cases/100,000 persons. Serotype b was the most common (66.67%), followed by non typeable H.influenzae (NTHi) (25%). Most isolates from adults were type b, while all isolates from pediatric population were non typeable. The most common biotype was type II, followed by type I and type III. Three of 24 isolates were β lactamase producers (12.5%). One isolate was β lactamase negative Ampicillin resistant (BLNAR). Resistance to ampicillin was 16.67%. Resistance to cephalosporins and fluoroquinolones was low (4-10%). Co-trimoxazole resistance was found to be very high (75%). All isolates were susceptible to azithromycin, tetracycline, chloramphenicol and meropenem. No isolates of H.influenzae type b were obtained from the paediatric population which may be due to the introduction of Hib vaccine. The increase in resistance to commonly used antibiotics is worrisome, especially penicillins and co-trimoxazole. Use of co-trimoxazole in empirical therapy of upper and lower respiratory tract infections has a high chance of failure in the current scenario.

OBJECTIVE The incidence of adenocarcinoma of esophagogastric junction is on the rise. The optimal treatment strategy for these tumours has not been clearly established. The aim of this study is to analyse the clinical presentations, management and outcomes following surgery in patients with adenocarcinoma of the esophagogastric junction presenting to a tertiary care centre in South India. METHODS Retrospective analysis of prospectively maintained database was performed. Data of all patients operated for adenocarcinoma of esophagogastric junction was analysed with regards to surgical management and clinico-pathological outcomes. RESULTS Fifty two patients underwent surgery for esophagogastric junction malignancy in our institution from January 2015 to December 2018. Among them, type I, type II and type III tumours contributed to 6, 16 and 30 patients, respectively. Thirty-four patients (65.4%) were male. Mean age of the patients was 57 years. Six patients (11.5%) received neoadjuvant therapy. Fourteen patients (26.9%) were found to have unresectable or metastatic disease during surgery. Six patients (11.5%) underwent multiorgan resection. Mean tumour length was 5.4cm. Number of lymph nodes retrieved ranged from 2 to 25. Majority of the patients had stage 3 disease on histopathological examination. Major postoperative morbidity (Clavien Dindo grade ≥ 3) was seen in 9 patients. Reoperation was required in 4 patients. In-hospital mortality rate was 11.53%. On follow up, locoregional recurrence was documented in 5 patients. CONCLUSION Esophagogastric junction adenocarcinoma is an aggressive malignancy with high incidence of unresectable or metastatic disease. Majority of patients presented with larger tumours and at an advanced stage of the disease leading to poor outcomes.

The aim of this study was to identify common stool parasites in patients attending a tertiary care centre in South India. We evaluated 2355 stool samples and parasites were detected in 7.9% of samples. 41.1% of our patients were in the 45–58-year age group. Protozoal infections were the commonest seen in 7.8% of samples. Entamoeba histolytica was the commonest protozoa (4.6%) followed by Entamoeba coli (1.2%) and Giardia (0.8%). Entamoeba histolytica and Entamoeba coli were together seen in 0.63%, and they were the commonest organisms seen in samples with multiple-organism infection. Both were equally detected in diarrheal samples.
