Looking beyond prevention of parent to child transmission: Impact of maternal factors on growth of HIV-exposed uninfected infant.

Background: Compared to HIV-infected children, relatively little has been described regarding the health status, particularly growth of HIV-exposed but uninfected children in resource-limited settings. This is particularly relevant with widespread implementation of the prevention of parent to child transmission program.

Methods: At a tertiary care health institute in India, a cohort of 44 HIV-exposed but uninfected children were followed through 6 months of age.

Role of quantitative pharmacokinetic parameter (transfer constant: K(trans)) in the characterization of breast lesions on MRI.

Background: The semi-quantitative analysis of the time-intensity curves in dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has a limited specificity due to overlapping enhancement patterns after gadolinium administration. With the advances in technology and faster sequences, imaging of the entire breast can be done in a few seconds, which allows measuring the transit of contrast (transfer constant: K(trans)) through the vascular bed at capillary level that reflects quantitative measure of porosity/permeability of tumor vessels.

Aim: Our study aims to evaluate the pharmacokinetic parameter K(trans) for enhancing breast lesions and correlate it with histopathology, and assess accuracy, sensitivity, and specificity of this parameter in discriminating benign and malignant breast lesions.

Diagnostic reliability of fine needle aspiration cytology against histopathology for the diagnosis of oral squamous cell carcinoma and oral leukoplakia.

Aim: The purpose of this study was to determine the possibility of using fine needle aspiration cytology (FNAC) as a primary diagnostic test in oral leukoplakia and squamous cell carcinoma.

Materials And Methods: This study consisted of clinically diagnosed 15 cases of leukoplakia and 15 cases of oral squamous cell carcinomas. FNAC and biopsy were done on all the cases.

Pre and post betahistine therapy 99m Tc - HMPAO brain spect studies in patients with vertigo.

Vertebro basilar insufficiency (VBI) is a well known cause of vertigo. Brain Single Photon Emission Computed Tomography (SPECT) is an important diagnostic tool to detect and to quantitate the perfusion abnormalities in different areas of the brain. Effect of an antivertigo drug Betahistine on improving the hypoperfusion in different areas of the brain in vertigo patients was studied using brain SPECT.
