Aim: The purpose of this study was to compare the difference in the output intensity of Light Emitting Diode (LED) light cure (LC) devices with and without a protective sleeve and its clinical significance.  Materials and Methods: The output intensity of 152 LC units in dental offices across the state of Odisha were examined. The collection of related information included an average number of e...

We study the origin of the Noise-Induced Hearing Losses (NIHL) in relation to the morphology and the physiology of the ear. We describe the mechanical and metabolic effects of the noises on the inner ear and their consequences on hearing. We discuss the importance and the limitations of the protective mechanisms. Finally, we present new possibilities to protect the ear against noise and to trea...

Workers in the salt industry are exposed to direct sunlight, salt dust and contact with brine. To assess their awareness, attitude and practices related to occupational health problems, 205 salt workers were interviewed about health hazards and problems related to their working conditions, usage of protective measures and suggestions for their improvisation. The brine workers had a fair knowled...

Recent correspondence in the British Medical Journall-4 has discussed the need for oxygen-failure devices and the philosophy of their design, so we shall not repeat this discussion here. Briefly, however, we think that very occasional oxygen failures are inevitable, during both anaesthesia and artificial ventilation with oxygen. Because the danger is so remote any safety device that is to gain ...

Patients suffering from Ménière's disease are particularly sensitive to negative pressure in the middle ear. For example, attacks of vertigo can be triggered by a descent in an aircraft when ventilation of the middle ear can become critical. Positive-pressure pulse treatment has been shown to have a beneficial effect on the symptomatology and is now a true alternative in the treatment of Ménièr...

The purpose of this study was to investigate the effective use of stanchions and handrails in buses. We constructed experimental equipment resembling bus stanchions and handrails and examined the grip and hold strength exerted when used. The total number of subjects was 80: 30 elderly and 19 young males, and 22 elderly and 9 young females. The experimental equipment comprised four parts: a hand...

A well fixed endotracheal tube is essential for safety during general anesthesia. In maxillofacial surgeries, securely fixing a nasotracheal tube in place has always been problematic. The aim of this article is to describe a simple but effective technique to fasten the nasotracheal tube using a wire support that allows a full range of head movement without interference in the surgical field. Du...

A survey of Ohio nursing homes was conducted in 2007 to examine whether injury rates were related to facility characteristics and availability of safety equipment. The median rate of injury in the 898 facilities was 5.7 injuries per 100 workers per year. Although 95% of the facilities had written resident lift-ing policies, only 22% of these were zero-lift policies. Gait transfer belts(99%) and...
