Harnessing deep learning for detection of diabetic retinopathy in geriatric group using optical coherence tomography angiography-OCTA: A promising approach.

The prevalence of diabetic retinopathy (DR) among the geriatric population poses significant challenges for early detection and management. Optical Coherence Tomography Angiography (OCTA) combined with Deep Learning presents a promising avenue for improving diagnostic accuracy in this vulnerable demographic. In this method, we propose an innovative approach utilizing OCTA images and Deep Learning algorithms to detect diabetic retinopathy in geriatric patients.

Multimodal dataset using OCTA and fundus images for the study of diabetic retinopathy.

This article presents a Multimodal database consisting of 222 images of 76 people wherein 111 are OCTA images and 111 are color fundus images taken at the Natasha Eye Care and Research Institute of Pune Maharashtra, India. Nonmydriatic fundus images were acquired using a confocal SLO widefield fundus imaging Eidon machine. Nonmydriatic OCTA images were acquired using the Optovue Avanti Edition machine Initially, the clinical approach described in this article was used to obtain the retinal images.

Atrio-ventricular regurgitations in constrictive pericarditis: incidence and post-operative outcome.

We studied 33 surgically proven cases of constrictive pericarditis during the period 1989-1991 by color Doppler echocardiography and angiography to look for incidence and postoperative outcome of atrioventricular regurgitation. The mean age was 27.2 + 16.

Color Doppler echocardiographic assessment of Sorin mitral prosthetic valve.

Doppler echocardiographic characteristics of 57 normally functioning Sorin prosthetic valves (a tilting valve) in the mitral position were studied in the early postoperative period. The three valve sizes (in mm) studied were: 25 (n = 15), 27 (n = 32) and 29 (n = 10). The mean gradients (mmHg) and the valve area (Sq cm) calculated by pressure half time method) for the three valve sizes were 3.

Infective endocarditis in children: profile in a developing country.

With the object of studying the profile of infective endocarditis in Indian children younger than 16 years of age, a retrospective study of 37 patients with infective endocarditis admitted to this hospital between January 1984 and December 1990 was carried out. There were 26 boys and 11 girls (aged 2-16 years (mean (SD) 10.3 (3.

Active infective endocarditis observed in an Indian hospital 1981-1991.

Clinical data from 186 patients (133 males and 53 females) with 190 episodes of infective endocarditis (IE) occurring between January 1981 and July 1991 were studied retrospectively at a large referral hospital in Northern India with the intention of highlighting certain essential differences from those reported in the West. The mean age was much lower (25 +/- SD 12 years, range 2 to 75 years). Rheumatic heart disease was the most frequent underlying heart lesion accounting for 79 patients (42%).

Profile of right-sided endocarditis: an Indian experience.

The clinical profile of right-sided infective endocarditis in India was studied from a review of records of patients with infective endocarditis admitted to this hospital. From November 1982 to November 1989, 109 patients with infective endocarditis showed vegetations on cross-sectional echocardiography confirming the diagnosis of infective endocarditis. In 19 (17.

Clinical profile and management of symptomatic patent ductus arteriosus in premature infants.

Twenty cases of symptomatic patent ductus arteriosus (PDA) in preterm inborn infants were studied retrospectively. The diagnostic criteria were a systolic or a systolodiastolic murmur, tachycardia (greater than 160 per minute), hyperdynamic precordium, collapsing arterial pulses, cardiomegaly or a need for intermittent positive pressure ventilation or continuous distending airway pressure. The incidence was found to be 2.

Antispermatogenic action of Celastrus paniculatus seed extract in the rat with reversible changes in the liver.

Biochemical, histochemical and histological studies of the effects of an oily extractive from the seeds of Celastrus paniculatus were done on the testes and liver of adult rats. The testis of treated animals showed vacuolization, germ cell depletion and arrest of spermatogenesis. The livers revealed focal necrosis in animals receiving 0.

Balloon atrial septostomy in infants with transposition of the great arteries (d-TGA): PGIMER experience.

Experience in use of Balloon Atrial Septostomy (BAS) in the palliation of infants with TGA is scanty from developing countries. We report 53 infants of d-TGA palliated with BAS in the period 1972 - 88 (mean age 2.03 +/- 1.

Complete A-V block and phrenic paralysis complicating surgical closure of ventricular septal defect--a case report.

The incidence of post-surgical complete A-V block has come down from 16% in the 50's to less than 1% with improvement in technique. Of these, 14% are transient and attributable to post-operative oedema and haemorrhage at the site of block. Permanent damage manifests early, or as late as 15 years, and in these, the risk of sudden death is a reality.

Evaluation of pulmonary hypertension in chronic rheumatic mitral regurgitation.

The incidence of pulmonary arterial hypertension (PAH) in 39 patients with angiographically proven chronic rheumatic mitral regurgitation (MR) is reported. The overall incidence of PAH were found to be 76.9%.
