Epidemiological analysis of SARS-COV-2 B.1.617.2 (delta variant) transmission in an educational institute.

Background: Despite having an effective COVID-19 vaccine, the COVID-19 pandemic is far from over and the delta variant continues to cause havoc across several continents. The present study was conducted to analyze and describe the occurrence of COVID-19 cases among completely vaccinated individuals.

Methods: In an educational institute in Western Maharashtra, we analyzed a cluster of RTPCR positive COVID-19 cases among fully vaccinated students which occurred in 12 days.

Usefulness of Wieneke criteria in assessing morphologic characteristics of adrenocortical tumors in children.

Purpose: Adrenocortical tumors (ACT) occur rarely in pediatric age group. Pediatric ACTs behave differently from their histologically similar adult counterparts and standard adult criteria often cannot accurately predict their clinical behavior. The aim of the present study was to document the clinicopathologic spectrum of pediatric ACTs and to assess the utility of Wieneke scoring system in predicting clinical behavior of these tumors.

Histopathological study of adrenocortical masses with special references to Weiss score, Ki-67 index and p53 status.

Background: Adrenal mass present with wide morphological spectrum and clinical manifestation, which can give rise to diagnostic confusion. Proper categorization is essential for individualized treatment.

Aim And Objective: (1) Application of Weiss criteria to differentiate between benign and malignant adrenocortical neoplasm (2) co-relation of Ki-67 and p53 expression with the Weiss score.

Metastatic vulvo-vaginal choriocarcinoma mimicking a Bartholin cyst and vulvar hematoma-two unusual presentations.

Metastatic choriocarcinoma may present solely as a vulvo-vaginal growth. It may pose initial diagnostic dilemmas and thus treatment delay. Two cases of metastatic choriocarcinoma which presented as vulvo-vaginal swelling are described here.

Evaluation of the prevention of parent to child transmission program in a rural tertiary care hospital of west bengal, India.

Background: In India, 67,500 infants acquire HIV infection yearly due to mother to child transmission.

Objective: The objective was to assess the operational aspect of the Prevention of Parent to Child Transmission (PPTCT) program in a tertiary care hospital and explore its bottleneck.

Materials And Methods: A 5-year (2004-2008) prospective evaluation study was conducted among the pregnant women attending Obstetrics Department of a rural tertiary care hospital, since the year of implementation.

Assessment of iodine and non-iodine deficiency hypothyroidism in women of reproductive ages in the sub-Himalayan plains of West Bengal.

Indian women of reproductive age groups commonly suffer from hypothyroidism which may be due to iodine or non iodine deficiency causes. This study was undertaken with a view to ascertain the leading cause of hypothyroidism in women of reproductive age group residing in the sub-Himalayan plain areas of Darjeeling district of West Bengal. Serum TSH, T4, T3 and Urinary Iodine Excretion (UIE) levels were measured in 101 non pregnant women.

Statistical characterizers of transport in communication networks.

We identify the statistical characterizers of congestion and decongestion for message transport in model communication lattices. These turn out to be the travel time distributions, which are Gaussian in the congested phase, and logarithmic normal in the decongested phase. Our results are demonstrated for two-dimensional lattices, such the Waxman graph, and for lattices with local clustering and geographic separations, gradient connections, as well as for a one-dimensional ring lattice with random assortative connections.

Optimized point dose measurement: An effective tool for QA in intensity-modulated radiotherapy.

In some cases of Intensity-modulated radiotherapy (IMRT) point dose measurement, there exists significant deviation between calculated and measured dose at isocenter, sometimes greater than ±3%. This may be because IMRT fields generate complex profiles at the reference point. The deviation arises due to lack of lateral electronic equilibrium for small fields, and other factors such as leakage and scatter contribution.
