background intentional lowering of blood pressure helps to produce a desirably clean surgical field. many drugs can be used to induce a hypotensive state, but due to their high potency and rapid effect, drugs that more easily and safely control the induction of hypotension are desirable. objectives to investigate the effects of premedication with oral clonidine on intraoperative bleeding and he...

radiotherapy in the head and neck region and chemotherapy might give rise to oral mucositis which is a severe and painful inflammation. there is no known definite cure for mucositis. a number of studies have attempted to evaluate the effect of low-power laser on radiotherapy- and chemotherapy-induced mucositis. the present study was undertaken to evaluate the effect of low-power laser on the pr...

background because of great concerns about mortality and morbidity of infection in febrile neutropenic patients, the appropriate empirical antibiotic should be started immediately. although there are established guidelines for the use of empirical therapy, local microbiological pattern and antibiotic susceptibility should be considered. objectives the current study aimed to identify the etiolog...

background: esophageal cancer is one of the major malignancies around the world. it is the 8th high frequency cancer and the 6th leading cause of cancer death worldwide. the etiology of esophageal carcinoma is thought to be related to the exposure of smoking, alcohol, nitrate and low socioeconomic status. in this study, the status of oral health was evaluated in the population living in the nor...

Two very low birthweight infants with severe clinical hyaline membrane disease requiring mechanical ventilation were dependent on slow-rate intermittent mandatory ventilation, without which they developed apnoea or hypopnoea and hypercarbia. Their ventilator dependence was apparently owing to inadequate ventilatory effort, and treatment with oral theophylline allowed easy weaning to continuous-...

Liquorice has an active substance, Glycyrrhizin which inhibits the conversion of precursor cortisol to cortisone by inhibiting the enzyme 11-betahydroxysteroid dehydrogenase. When imbibed, liquorice acts like hyperaldosteronism which presents with typical symptoms including high blood pressure, low blood potassium, and muscle pain and weakness. This article appraises physiological and pharmacol...

A rapid microspectrophotometric method was used to measure zinc concentrations in plasma and erythrocytes. A circadian variation in plasma zinc related to the ingestion of food was observed. Fasting plasma zinc concentrations were low in 20 out of 23 paraplegic patients with pressure sores, indicating that oral zinc supplementation may be expected to accelerate healing in such patients. Erythro...

The patient’s clinical situation was characterised by a normal pulmonary pressure and a transient need for oxygen supplementation; only low doses of oral prednisone were required. Presently, it is not possible to predict the patient’s clinical course, as no other similar cases have been reported. Lung transplantation currently represents the only treatment option for this disease, but it is hop...

To evaluate the influence of salt sensitivity on the blood pressure response to oral indomethacin treatment, we studied 35 hospitalized essential hypertensive patients (24 men and 11 women, aged from 40 to 55 years). During a normal NaCl intake (120 mmol Na+ per day), patients were assigned to receive in a randomized double-blind fashion either 200 mg indomethacin (25 patients) or placebo (10 p...

medication errors and adverse drug events can bring about hospitalization, permanent injury, or death. patients due to lack of adequate understanding of instruction may unintentionally misuse a prescribed medicine. the aims of the study were to examine whether patients with low back pain were correctly able to understand physician's instructions regarding drug use and also to identify influenci...
