Immunogenicity of SARS-CoV-2 vaccines BBV152 (COVAXIN®) and ChAdOx1 nCoV-19 (COVISHIELD™) in seronegative and seropositive individuals in India: a multicentre, nonrandomised observational study.

Background: There are limited global data on head-to-head comparisons of vaccine platforms assessing both humoral and cellular immune responses, stratified by pre-vaccination serostatus. The COVID-19 vaccination drive for the Indian population in the age group 18-45 years began in April 2021 when seropositivity rates in the general population were rising due to the delta wave of COVID-19 pandemic during April-May 2021.

Methods: Between June 30, 2021, and Jan 28, 2022, we enrolled 691 participants in the age group 18-45 years across four clinical sites in India.

Evaluation of Hematological profile in Oral Submucous Fibrosis: A Cross-sectional Study.

Aims: The purpose of this study was to estimate hemoglobin (Hb) level, red cell indices (RCIs), serum iron level and Vitamin B12 level in patients with oral submucous fibrosis (OSMF) and to analyze the association of these parameters in different stages of OSMF.

Setting And Design: This case-control study comprised of 65 individuals, with 40 OSMF patients and 25 controls. The OSMF patients were graded clinically according to the classification by Arakeri .

A Peek Into the Future: How a Pandemic Resulted in the Creation of Models to Predict the Impact on Sexually Transmitted Infection(s) in New York State (Excluding New York City).

During the initial height of COVID-19 in New York State excluding New York City in March 2020, reports of sexually transmitted infections declined. Prediction models developed to estimate the incidence of early syphilis and gonorrhea during the COVID-19 pandemic were used to study impact on STI diagnoses/reporting and inform sexual health program planning.

An orthopantomographic study of prevalence of hypodontia and hyperdontia in permanent dentition in Vadodara, Gujarat.

Background: Developmental anomalies in the number of teeth can result from disturbances in the developing dental lamina of the tooth. The dental lamina may become hyperactive leading to the formation of a supernumerary tooth or may fail to proliferate leading to the congenital absence of a primary or permanent tooth.

Aims: The aim of the study was to assess the prevalence and distribution of hypodontia and hyperdontia in permanent dentition, excluding the third molars in children in Vadodara, Gujarat.

Respiratory virus prophylaxis in congenital heart disease.

Respiratory syncytial virus (RSV) is the leading cause of acute lower respiratory tract infections and causes up to 200,000 infant deaths a year worldwide. The average rate of hospitalization for severe RSV infection is 5 per 1000 children, and the rate is three-times higher in those with congenital heart disease (CHD). Palivizumab, a monoclonal antibody, reduces hospitalization rates and intensive care admissions.

Prevalence of commissural lip pits in population of central Gujarat: A hospital-based study.

Background: Commissural lip pits (CLPs) fall among the rare congenital deformities recorded. CLP usually follows dominant hereditary pattern and may be associated with other congenital defects. CLP can appear as unilateral depression or bilateral depression.

Immuno-Histochemical and Quantitative Study of Melanocytes and Melanin Granules in Oral Epithelial Dysplasia.

Introduction: Oral Epithelial dysplasia (OED) is a potentially malignant disorder that is characterized by the presence of architectural and cytological changes. One of the prime factors responsible for the development of these lesions is the usage of tobacco. A variety of factors provide protective mechanism in order to prevent the effects of chemotoxic agents including tobacco products of which, melanin pigmentation is one of the vital elements.

Kawasaki disease and coronary artery aneurysms: from childhood to adulthood.

Kawasaki disease is an acute, systemic vasculitis of childhood and confers a 25% risk of developing coronary artery aneurysms. Its etiology is unknown, but the incidence is increasing rapidly with linked gene polymorphisms having been identified. A constellation of symptoms, epidemics and seasonality all implicate an unidentified infective or environmental cause.

Prevalence of most commonly reported tobacco-associated lesions in central Gujarat: A hospital-based cross-sectional study.

Background: Oral cancer is a major health problem in tobacco users worldwide and is one of the ten most common cancers. India alone accounts for 1/3 rd of the world's oral cancer and has a high rate of potentially malignant disorders (PMDs). The most common predisposing factors are smoking, smokeless tobacco, betel nut in quid form (pan), alcohol, spicy food, and sharp broken tooth.

Assessment of nerve conduction study to establish most common electrophysiological predictor of lumbosacral radiculopathy among radiologically diagnosed L5S1 neural foramina compression cases.

Magnetic resonance imaging (MRI) and electromyography (EMG) are complimentary investigations in diagnosis of lumbosacral radiculopathy (LSR). With changing pattern of S1 electrodiagnosis by H-reflex study measures, electrophysiological studies were conducted to establish most common electrophysiological predictors of LSR in MRI diagnosed L5S1 neural foramina compression subjects. Fifty subjects, with definite L5S1 neural foramina compression underwent electrophysiological evaluation and the data was analyzed using established electrodiagnostic criteria.

Multistate outbreak of listeriosis associated with cantaloupe.

Background: Although new pathogen-vehicle combinations are increasingly being identified in produce-related disease outbreaks, fresh produce is a rarely recognized vehicle for listeriosis. We investigated a nationwide listeriosis outbreak that occurred in the United States during 2011.

Methods: We defined an outbreak-related case as a laboratory-confirmed infection with any of five outbreak-related subtypes of Listeria monocytogenes isolated during the period from August 1 through October 31, 2011.

Prevalence of Diabetic Retinopathy in Western Indian Type 2 Diabetic Population: A Hospital - based Cross - Sectional Study.

Context: Diabetic Retinopathy (DR) can be defined as a damage which is caused to microvasculature in the retina by prolonged hyperglycaemia. Various studies have been conducted in south India, to find out prevalence of DR. It remains a less explored domain among type 2 diabetic patients in western India.

Oral lichen planus: a report and review of an autoimmune-mediated condition in gingiva.

Oral lichen planus (OLP) is a chronic autoimmune, mucocutaneous disease that affects the oral mucosa as well as the skin, genital mucosa, scalp, and nails. It is one of the most common dermatological diseases presenting in the oral cavity. An immune-mediated pathogenesis is recognized in lichen planus, although the exact etiology is unknown.

Variations in impacted mandibular permanent molars: Report of three rare cases.

The impaction of permanent teeth is not uncommon, but few permanent teeth are rarely impacted like mandibular first and second molars. Though third molars are commonly impacted, inversely impacted mandibular third molars are very rare. Here, we report three unusual cases of impacted mandibular molars accidentally diagnosed on conventional radiographs.

Estimation and comparative study of serum total sialic acid levels as tumor markers in oral cancer and precancer.

Background: Tumor markers are a major part of the secondary prevention and thus the detection of malignancies. Neoplasms often have an increased concentration of sialic acid on the tumor cell surface and are shed or secreted by some of these cells which increase the concentration in blood.

Materials And Methods: The study was conducted on 90 subjects equally divided into three groups viz, healthy individuals, oral cancer and precancer.

Colostomy shift en masse--a new procedure.

Colostomy shift en masse is a novel technique in which the colostomy is shifted along with a rim of skin and abdominal wall tissue. This provides additional length of distal bowel if needed during pull-through anastomosis. We have treated three cases (two Hirschsprung's disease and one anorectal malformation) with colostomy shift en masse, and have achieved good results.
