Molecular and serological evidence of chikungunya virus infection with high case fatality among pediatric population with acute encephalitis syndrome: first report from Eastern Uttar Pradesh, India.

Acute encephalitis syndrome (AES) outbreaks in children of Eastern Uttar Pradesh (E-UP) region of India have been a longstanding public health issue, with a significant case fatality rate of 20-25%. Since past decade, a rise in chikungunya (CHIK) cases has been occurring, which is a reported etiology of AES. However, the burden of chikungunya virus (CHIKV) among pediatric AES (pAES) is unknown from E-UP. We included 238 hospitalized pAES cases. The presence of IgM antibodies for CHIKV, and Dengue virus (DENV) was tested, and RT-PCR was performed for CHIKV and DENV in serologically confirmed CHIKV and DENV pAES cases. Positive samples were sequenced using Sangers sequencing. Further, to check for co-infection, IgM antibodies for other AES etiologies including Japanese encephalitis virus (JEV), Leptospira and Orientia tsutsugamushi (OT) in serum were also investigated. IgM ELISA demonstrated 5.04% (12) positivity for CHIKV. Among CHIKV IgM positive, 3 (25%, 3/12) pAES patients died. CHIKV genome was detected in 3 pAES specimens. Among which, 2 CHIKV cases were also positive for OT DNA. Partially sequenced CHIKV were genotyped as ECSA. The overall finding indicates evidence of CHIKV infection with high case fatality among pAES patients from E-UP. This study advocates constant serological and molecular surveillance of CHIKV in AES endemic regions of India.

Vaccine hesitancy for coronavirus SARS-CoV-2 in Varanasi India.

With the rollout of the world's largest vaccine drive for SARS-CoV-2 by the Government of India on January 16 2021, India had targeted to vaccinate its entire population by the end of 2021. Struggling with vaccine procurement and production earlier, India overcome these hurdles, but the Indian population still did not seem to be mobilizing swiftly toward vaccination centers. The severe second wave has slowed the vaccination pace and was also one of the major contributing factors to vaccine hesitancy. To understand the nature of vaccine hesitancy and its underlying factors, we conducted extensive online and offline surveys in Varanasi and adjoining regions using structured questions. Most respondents were students (0.633). However, respondents from other occupations, such as government officials (0.10), have also participated in the study. Interestingly, most people (0.75) relied on fake news and did not take COVID-19 seriously. Most importantly, we noticed that a substantial proportion of respondents (relative frequency 0.151; mean age 24.8 years) reported that they were still not interested in vaccination. We observed a significant association between vaccine hesitancy and socioeconomic status (χ2 = 307.6, p < 0.001). However, we failed to detect any association between vaccine hesitancy and gender (χ2 = 0.007, p > 0.5). People who have neither been vaccinated nor have ever been infected may become the medium for spreading the virus and creating new variants, which may lead to the vaccine-resistant variant. We expect this extensive survey to help the Government upgrade their vaccination policies for COVID-19 in North India.

Factors predicting recovery of liver function after percutaneous drainage in malignant biliary obstruction: the role of hospital-acquired biliary sepsis.

AIM OF THE STUDY: Prolonged cholestasis adversely affects liver function. Hepatic functional recovery is mandatory prior to any surgical or medical intervention. Serum bilirubin levels correlate well with, and are a surrogate marker for, hepatocyte function. We aimed to ascertain factors responsible for slow decline of bilirubin and delayed recovery of liver function following percutaneous drainage in malignant biliary obstruction. MATERIAL AND METHODS: Sixty-seven patients with malignant jaundice who underwent percutaneous biliary drainage (PTBD) were followed until they achieved target bilirubin ≤ 3 mg/dl. According to duration, patients were divided into early (≤ 6 weeks, n = 43) and late (> 6 weeks, n = 24) groups. Various clinical, tumour-related and procedure-related factors were analysed for their contribution to delayed recovery with the χ2 or t-test. Multi-variate logistic regression analysis was used to predict independent associations. RESULTS: Gallbladder cancer presenting with type I block was the commonest pathology. Overall demographic, clinical, tumour characteristics and procedural details were comparable between groups. Duration of jaundice (p = 0.026), liver involvement (p = 0.041), baseline total (p = 0.001) and direct bilirubin levels (p < 0.001), positive bile cultures with hospital-acquired bacteria (p = 0.031) were significant factors on univariate analysis. Bacterial growth was significantly greater following repeated biliary manipulations. The commonest organisms were Pseudomonas and Citrobacter spp. Number of re-instrumentations, post-procedural biliary sepsis and native biliary organisms were non-contributory. No factor was significant on multivariate analysis. CONCLUSIONS: Factors directly linked to extent and duration of disease are validated as significant contributors to functional recovery after biliary drainage. Biliary sepsis with hospital-acquired organisms, especially following re-interventions is a significant modifiable risk-factor affecting bilirubin decline.

Giant splenic lymphangiomatosis in adult: a diagnostic dilemma.

Cystic lymphangiomatosis of the spleen occurs secondary to developmental malformation of the lymphatic system. It is one of the rare entities generally seen in children. It is usually seen in children. We report a case of cystic lymphangiomatosis of the spleen occurring in an adult woman presenting with massive splenomegaly. Total splenectomy was considered to be the treatment of choice for making definitive diagnosis and to exclude the presence of malignancy or other causes of massive splenomegaly.
