Ensuring Transfusion Safety: Screening Blood Donors for Human Parvovirus B19.

Ensuring the safety of blood and blood products is a vital aspect of healthcare. The potential for transmission of pathogens through blood and blood products makes transfusion safety a significant concern. Despite advancements in testing methodologies, donated blood products still pose a risk for infection transmission.

Increased parvovirus B19 seropositivity in healthy blood donors in India.

A core component of every blood program is the supply of safe blood and blood products. The elevated risk of transmission through these products is due to parvovirus B19 (B19V) resistance to the virus inactivation procedures. Our study aimed to screen asymptomatic blood donors for B19V at a tertiary care hospital in Chennai, Tamil Nadu, between September 2020 and June 2021.

Are Emerging Pathogens in patients with underlying morbidity: A case series.

is a genus consisting of several species including the group, complex and other phytopathogens. species is a gram-negative bacillus with protean presentation that can be acquired from various sources, including water, soil, plant surfaces, and hospital environments. The organism on Gram staining is seen as gram-negative rod and on culture, the colonies are non-lactose fermenting.

Epstein-Barr virus (EBV) DNAemia in saliva of viral encephalitis and nasopharyngeal carcinoma patients.

Epstein-Barr virus (EBV) is a lymphotropic virus that causes diseases ranging from a flu-like illness called infectious mononucleosis to nasopharyngeal carcinoma, Burkitt's lymphoma, and central nervous system (CNS) infection. Detection of EBV DNA is usually done using whole blood samples taken from the patients. We undertook the detection of EBV in blood, cerebrospinal fluid (CSF), and saliva by real-time quantitative PCR in two patients, one with a history of nasopharyngeal carcinoma, and the other having a case of viral encephalitis.

Are we dealing with melioidosis under the mask of tuberculosis? - A case series.

Melioidosis is prevalent in South-East Asia. India is now become endemic to melioidosis. Melioidosis mimicks Tuberculosis (TB) and is often overlooked clinically.

A shift in circulating rotaviral genotypes among hospitalized neonates.

In neonates, rotavirus (RV) infection is generally nosocomial. The control of rotaviral infection within hospital settings is challenging due to prolonged shedding of the virus and contamination of the surrounding environment. There are few studies that have reported asymptomatic infection within neonates.

Hepatitis B virus X protein: The X factor in chronic hepatitis B virus disease progression.

Introduction: Hepatitis B virus (HBV) is the most common aetiological factor causing hepatocellular carcinoma (HCC). HBx gene plays an enigmatic role in HBV-related HCC. In this study we have analysed amino acid substitutions in HBx from HBV-infected individuals of different clinical stages.

Detection of cytomegalovirus disease by real-time quantitative PCR targeting immediate early gene (ppUL83) in different samples among post-renal-transplant recipients.

Renal transplantation is a treatment option for end-stage renal disease (ESRD). Cytomegalovirus (CMV) infection was analysed among symptomatic and asymptomatic post-renal-transplant recipients (PRTRs). A total of 30 PRTRs were enrolled.

Sequencing of from saliva in patients with periodontitis and type 2 diabetes mellitus.

Background: Porphyromonas gingivalis is a major periodontal pathogen. Saliva is the most easy, non-invasive microbiological sample for detection of periodontal pathogens.

Aim And Objectives: A prospective study on 37 diabetic patients was grouped into well-controlled diabetes with/without periodontitis and uncontrolled diabetic with periodontitis.

Next generation sequencing of oral microbiota in Type 2 diabetes mellitus prior to and after neem stick usage and correlation with serum monocyte chemoattractant-1.

Introduction: Oral microbiome impacts health and disease. T2DM and periodontitis are associated. Neem (Azadiracta indica) has antibacterial activity against oral microbiota.

Maculopapular rash presentation of febrile illness in an adult with Varicella zoster virus infection.

Varicella zoster usually manifests as maculopapular rash (MPR), which later progresses to vesicle. It can also manifest as MPR without progression to the vesicle stage. This atypical manifestation is more common in adults and immunocompromised patients.

Serum monocyte chemoattractant protein-1 is a biomarker in patients with diabetes and periodontitis.

Introduction: The role of serum Monocyte Chemoattractant Protein-1 (MCP-1) as a biomarker of periodontitis is well documented; however, its role in diabetic patients with periodontitis is unknown.

Aim: This study was conducted to determine the presence and concentration of serum MCP-1 in diabetic patients with and without periodontitis and correlate it glycemic status with periodontitis.

Materials And Methods: Adult diabetic patients were enrolled and grouped into group I, II, and III based on their glycemic status and serum MCP-1 estimated by ELISA.

Improved detection of Mycobacterium tuberculosis using two independent PCR targets in a tertiary care centre in South India.

Introduction: Tuberculosis (TB) causes significant morbidity and mortality worldwide as one of the leading infectious diseases. In India, more than 1.8 million new cases occur every year.
