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.

H Syndrome - A Case Report.

This case report describes a case of H syndrome with characteristic cutaneous hyperpigmentation, hypertrichosis, sclerodermatous thickening, and multisystem involvement such as hearing loss and heart anomaly in an Indian patient. There are around 100 cases of this rare, autosomal recessive genodermatosis reported in the literature, out of which 10 cases are from the Indian population. The aim of this paper is to increase awareness about this novel inherited form of histiocytosis and insist on the role of dermatologists to identify such patients in our population where consanguinity is prevalent.

Diagnosis of asymptomatic bacteriuria and associated risk factors among pregnant women in mangalore, karnataka, India.

Background: Asymptomatic bacteriuria (AB) is common inwomen and increases in prevalence with age or sexual activity. Prompt detection and treatment of this condition and associated factors decreases complications like acute pyleonephritis, intrauterine growth retardation and preterm labour. Chromogenic media is a versatile tool in rapid primary screening of the causative organisms considerably reducing daily routine workload.

Co-Infection: Weil's Syndrome with Hepatitis B Infection- A Diagnostic and Therapeutic Hitch.

Undifferentiated Acute Febrile Illness (AFI) is a common clinical syndrome among patients seeking hospital care. Detection of co-infections at the time of presentation is a diagnostic challenge, especially with limited laboratory support. Even if detected, early treatment and cure of these co-infections can be difficult for the clinicians.

Fusarium Solani: a causative agent of skin and nail infections.

Fusarium spp are non-dermatophytic hyaline moulds found as saprophytes and plant pathogens. Human infections are probably a result of various precipitating predisposing factors of impaired immune status. Immunocompetent individuals of late are also vulnerable to various unassuming saprophytic and plant pathogens.

Therapeutic misadventure with paracetamol in children.

Paracetamol (acetaminophen), though considered a safe, "over the counter" analgesic and antipyretic, can cause liver injury with overdose. Therapeutic misadventure is a unique problem where the existing nomogram used for acute poisoning is not applicable. In this context, early initiation of N-acetylcysteine even before a biochemical evidence of liver injury may be beneficial.

Systemic melioidosis presenting as suppurative parotitis.

A 3 year old child was brought with fever, left parotid swelling and altered sensorium. Cultures from blood, pus and throat swab grew Burkholderia pseudomallei. A diagnosis of septicemic melioidosis with encephalopathy was made.

Spectrum of melioidosis in the suburbs of Mangalore, S West Coast of India.

Melioidosis is an emerging infection in India. Seventeen cases of culture proven melioidosis are reported in this study. The isolation rate was high during the rainy season.

Melioidotic pericardial effusion.

Aim is to present a rare case of purulent pericardial effusion caused by Burkholderia pseudomallei. Pericardial sample was inoculated into Bactec Peds Plus/F broth of the Bactec automated system. After the system flagged positive, the broth was subjected to Gram stain, biochemical tests and drug susceptibility.

Timing of zero dose of OPV, first dose of hepatitis B and BCG vaccines.

The Indian Academy of Pediatrics has been recommending Hepatitis B vaccination for infants since 1992. This community based cross sectional study carried out in the rural and urban areas of Tamil Nadu found no significant rural urban difference in the proportions of children who had received BCG in 3 days/7 days and OPV-zero dose in 3 days/7 days after birth. The proportion of children who had received first dose of Hepatitis B in 3 days was significantly lower than those who had received BCG and OPV within 3 days after birth.

Clozapine-induced cardiac failure.

A 73-year-old woman with dementia was given clozapine for treatment-resistant psychotic symptoms. Subsequently, she developed cardiac failure. Caution should be exercised when using clozapine, especially in the elderly.

Numerical study of reverse period doubling route from chaos to stability in a two-mode intracavity doubled Nd-YAG laser.

We have numerically studied the behavior of a two-mode Nd-YAG laser with an intracavity KTP crystal. It is found that when the parameter, which is a measure of the relative orientations of the KTP crystal with respect to the Nd-YAG crystal, is varied continuously, the output intensity fluctuations change from chaotic to stable behavior through a sequence of reverse period doubling bifurcations. The graph of the intensity in the X-polarized mode against that in the Y-polarized mode shows a complex pattern in the chaotic regime.

Hypertension in the Parsi community of Bombay: a study on prevalence, awareness and compliance to treatment.

Background: Uncontrolled hypertension (HT) is an established risk factor for the development of vascular diseases. Prevalence varies in different communities and no such study has been conducted in the Parsi community living in Bombay, India. The objectives of this study were to determine the prevalence, awareness, compliance to medication and control of HT in this community.
