Prospective multi-centric study to analyze pre-transplant compatibility algorithm for live-related donor kidney transplant in Indian setting: the "Delhi approach"!

Background: Since no single test is always accurate and sensitive, two or more tests are used to increase the precision of evaluation. Different algorithms have been proposed by centers in Leiden, Basel, Vienna and Minnesota, etc. With an intention to develop an optimal algorithm for India, we evaluated pre-transplant compatibility tests for live-donor kidney transplants.

Combination of capsular tension ring and capsular tension segment for the management of lens coloboma >4 clock hours.

Lens colobomas extending more than 4 clock hours and causing visual impairment require lens extraction along with capsular support devices with scleral fixation for adequate centration of the capsular bag and for prevention of capsular fornix aspiration with inadvertent extension of zonular dialysis intraoperatively. In this case series, we describe a technique for the management of isolated lens colobomas involving 4-5 clock hours by clear lens extraction and intraocular lens implantation using a combination of a capsular tension ring with a capsular tension segment (CTS) for the centration and stability of the capsular bag. Hoffman's corneoscleral pocket and half-bow sliding knot technique were used for scleral fixation of the CTS.

Long-Term Ophthalmic Outcomes in Pediatric Orbital Cellulitis: A Prospective, Multidisciplinary Study From a Tertiary-Care Referral Institute.

Purpose: To analyze the clinical profile, radiological features, and ophthalmic outcomes of the multidisciplinary management of children with pediatric orbital cellulitis.

Methods: A prospective, interventional study of patients diagnosed as having pediatric orbital cellulitis was conducted. A complete history, clinical examination, laboratory work-up, radiology (computed tomography [CT]), multidisciplinary consultations (otolaryngology, pediatrics, and microbiology), and treatment plan were obtained for all children.

Immune keratitis: An unusual primary presentation of neuro-Behçet's disease.

A 19-year-old Nepalese male presented with complaints of bilateral ocular discomfort, photophobia, watering, and redness for 1 week. Visual acuity was 6/12 and 6/60 in the right and left eye, respectively. On biomicroscopic examination, presence of peripheral stromal infiltrates with conjunctival follicles was noted; infiltrates progressed to involve central cornea with further decrease in vision over next few days.

Establishing a sample-to cut-off ratio for lab-diagnosis of hepatitis C virus in Indian context.

Introduction: Lab-diagnosis of hepatitis C virus (HCV) is based on detecting specific antibodies by enzyme immuno-assay (EIA) or chemiluminescence immuno-assay (CIA). Center for Disease Control reported that signal-to-cut-off (s/co) ratios in anti-HCV antibody tests like EIA/CIA can be used to predict the probable result of supplemental test; above a certain s/co value it is most likely to be true-HCV positive result and below that certain s/co it is most likely to be false-positive result. A prospective study was undertaken in patients in tertiary care setting for establishing this "certain" s/co value.

Confirmation and follow up of initial "NAT yields": Prospective study from a tertiary healthcare center in India.

Background: In India variable rate of "NAT yield" has been demonstrated in several published reports. This study was performed with the objective to know the rate of "true NAT yield" in blood donors by confirmation with supplementary tests and follow up of initial "NAT yield" donors.

Materials And Methods: A total of 48,441 blood donors were tested for HIV, HBV and HCV with enhanced chemiluminescence and ID-NAT.

Enhanced hepatitis B virus (HBV) pre-genomic RNA levels and higher transcription efficiency of defective HBV genomes.

Defective hepatitis B virus (dHBV) particles contain genomes corresponding to singly spliced HBV RNA. A limited number of studies show that dHBV is present in all chronically HBV-infected patients. Clinical studies have linked dHBV and dHBV gene products to high virus loads and liver damage.

Etiology and survival of aplastic anemia: a study based on clinical investigation.

Background: Management of aplastic anemia is etiology driven, whether constitutional or acquired. Age, gender, and severity of disease also play crucial role in the survival of aplastic anemia. Since, inadequate data are available from India, the present study was conducted with the aim to evaluate the etiology and survival of aplastic anemia.
