background and aim: the elderly afflicted with hearing loss experience the consequent problems of falling and imbalance. some rea­sons have been reported for the relationship between hearing loss and imbalance. however, a large part of the population of the elderly does not experience hearing assessments and if such assessments are done, the right rehabilitation services are not offered. this s...

Cardiovascular function is regulated by a dynamic balance comprised of sympathetic and parasympathetic influences. Sympathetic regulatory centers include the rostra ventrolateral medulla (RVLM) and paraventricular nucleus of hypothalamus (PVN). Pre-sympathetic neurons (PSNs) in these centers project directly to sympathetic preganglionic neurons in the intermediolateral nucleus of the thoracic s...

Ruminal lactic acidosis is a condition that arises in ruminants due to the ingestion of excess quantities of easily digestible grains leading to diarrhea, anorexia and physiological derangements which can be fatal in severe cases. A clinical case of cow with history of rice flour ingestion showing signs of acute ruminal lactic acidosis was managed. The pH of ruminal fluid was 5.1. The number of...

Vestibular lesions may cause imbalance that long outlasts vertigo. Photographic analysis in five cases showed defects not only of the tilting reactions, which are of labyrinthine origin, but also of certain other postural reactions, notably the counterpoising and protective stepping reactions. All of these reflexes are unconscious and consequently such patients are rendered unstable in several ...

Myocardial ischemia results from an imbalance between oxygen supply and demand. After coronary occlusion, oxygen supply and demand mismatch produces a series of physiological alterations that can precede clinical symptoms (1). Impaired myocardial perfusion is an early event in the “ischemic cascade” that can be assessed using clinically available noninvasive imaging. Both extent and severity of...

Trauma is the major cause of death worldwide. Survival of the major trauma victims can be improved by the principles of damage control surgery. The vicious cycle of trauma triad, namely, hypothermia, coagulopathy and acidosis should be intercepted by the quick abbreviated laparotomy and subsequently physiological imbalance is corrected by secondary resuscitation in the surgical intensive care u...

BACKGROUND Previous surveys of psychological strain in the Naval Service (NS) have shown higher than expected levels of strain when compared to the general population. AIM To repeat the survey last carried out in 2004 and to obtain further information on the nature of the occupational stressors associated with strain. METHODS General Health Questionnaire-12 strain rates and job/life stresso...
