OBJECTIVES: Traditionally Capillary refilling time (CRT) has been used as a widely accepted method to assess cardiac output and peripheral circulation in neonates. There are only few studies describing normal values and the correct method of recording CRT. The value of CRT is affected by various factors like ambient or skin temperature, age, site of measurement, duration as well as amount of pressure and inter observer variation. However, none of these have been standardized. Hence, we conducted this study to establish the normal value and factors affecting Capillary Refilling Time (CRT) in healthy neonates in Varanasi...

A carbohydrate (CHO) solution consumed before exposure to hypoxia has been reported to reduce arterial oxygen desaturation at rest. The purpose of this study was to determine whether this effect occurred during exercise and when the CHO load is part of a meal. Eleven male subjects (mean age 20.1 ± 1.8 years, BMI 24.3 ± 2.4 kg m(2)) consumed either a high-CHO (2,340 kJ, 70 % CHO, 12 % protein) or an isoenergetic high-protein (35 % CHO, 48 % protein) breakfast meal 60 min before being exposed to 15 min of hypoxia (F(I)O(2) = 13...

Nonobtrusive pulse rate measurement using a webcam is considered. We demonstrate how state-of-the-art algorithms based on independent component analysis suffer from a sorting problem which hinders their performance, and propose a novel algorithm based on constrained independent component analysis to improve performance. We present how the proposed algorithm extracts a photoplethysmography signal and resolves the sorting problem. In addition, we perform a comparative study between the proposed algorithm and state-of-the-art algorithms over 45 video streams using a finger probe oxymeter for reference measurements...

In Buerger's disease conservative treatment is questionable. Arterial reconstructive surgery is not feasible and sympathectomy has limited role. Progression of the disease invariably leads to amputation. Ilizarov's method increases the vascularity of the ischaemic limb. Retrospective analysis of Ilizarov's technique in 60 patients was done. Immediate results took into account rest pain, colour of skin, venous return, temperature, pulse oxymeter measured oxygen saturation and ulcer/amputation stump wound healing...

INTRODUCTION: Obstructive sleep apnoea syndrome (OSAS) constitutes a new major public health problem because of its several pathophysiologic consequences such as cognitive disorders, excessive daytime sleepiness with risks of traffic accidents, cardiovascular implications, and decrease of quality of life. The necessity of a gold-standard polysomnography to ensure an accurate diagnosis implies an expensive, technical and time-consuming examination. Thus, it seems logical to develop new systems so as to diagnose SAS and to make it possible to detect apnoeas/hypopnoeas easily during sleep even at home...

In Hungary, the Institute of Health Sciences at Semmelweis University was the first institution to introduce patient simulation-based practical training of non-physician professionals. Before introducing this novel educational methodology, students could only practice particular examinations and interventions on demonstration tools. Using the simulator they can also follow and analyze the effects of the interventions that have been made. The high fidelity, adult Human Patients Emergency Care Simulator (HPS-ECS, Medical Education Technologies Incorporation, Sarasota, Florida, USA) is particularly suitable for acquiring skills related to the management of various emergency situations...
