Tiotidine and cimetidine--kinetics and dynamics

Tiotidine and cimetidine kinetics and dynamics were compared to assess mechanisms of the longer duration of effect of tiotidine in man. Both drugs has similar lag times for absorption. Tiotidine with a meal was more slowly absorbed than when fasting and was also more slowly absorbed than cimetidine with a meal. The elimination rates for both drugs did not differ; they were both approximately 2 to 3 hr. Oral doses of cimetidine achieved areas under the plasma concentration curve approximately three times that of tiotidine but these concentrations were only 1/10 as potent. The cimetidine concentration inducing 50% inhibition of food-stimulated gastric acid secretion was 0.41 +/- 0.04 whereas it was 0.04 +/- 0.003 microgram/ml for tiotidine. The effect of tiotidine lasted longer than that of cimetidine because the doses recommended for use in man resulted in higher concentrations in plasma relative to effective concentration than clinical doses of cimetidine.     

Developments and trends in traditional medicine and complementary and alternative medicine

With the rapid development of society, medical science and technology, although quality of life is enhanced and life expectancy is prolonged, aging, environmental changes and health problems are unavoidable. More and more people, therefore, are concerned about their health and place high demands on medical care. As modern medicine cannot meet all such demands, other medical care systems emerge. Trends in the seeking of medical care show that people are inclined towards natural approaches, so attention is being paid once again to traditional medicine, as well as complementary and alternative medicine. Under the patient-oriented concept, medical personnel have to recognize means of health care while thinking of the individualized and socioeconomic impacts. The purpose of this paper therefore is to provide medical personnel with information on the developments and trends in, knowledge and research with regard to traditional medicine as well as complementary and alternative medicine.     

Anatomy and physiology of feeding and swallowing: normal and abnormal

Eating and swallowing are complex behaviors involving volitional and reflexive activities of more than 30 nerves and muscles. They have two crucial biologic features: food passage from the oral cavity to stomach and airway protection. The swallowing process is commonly divided into oral, pharyngeal, and esophageal stages, according to the location of the bolus. The movement of the food in the oral cavity and to the oropharynx differs depending on the type of food (eating solid food versus drinking liquid). Dysphagia can result from a wide variety of functional or structural deficits of the oral cavity, pharynx, larynx, or esophagus. The goal of dysphagia rehabilitation is to identify and treat abnormalities of feeding and swallowing while maintaining safe and efficient alimentation and hydration.     

骨质疏松症及其防治

骨质疏松 (Ｏｓｔｅｏｐｏｒｏｓｉｓ)是一种以骨量减少为特征、骨组织显微结构发生改变和骨折发生频度增加的疾病 ,估计全世界大约有两亿患者 ,我国的患者 (按比较保守的估计 )近 6 0 0 0万。近三十多年来世界各国都对此病进行了比较全面和深入的研究 ,我国政府对此病症也十分重视 ,从 1985年开始 ,就将骨质疏松的研究列入我国“七五”攻关课题 ,在全国范围内组织了大量的人力、物力进行了骨质疏松的主要诊断依据的研究、骨矿含量的调查及流行病学的调查 ,获得了诸多有价值的成果 ,基本上模清了中国人骨骼生长、发育、衰老的规律 ,确定了骨…     

Acupressure and postoperative nausea and vomiting

Despite great strides during the preceding 3 decades, the ability to consistently eliminate postoperative nausea and vomiting (PONV) continues to elude anesthesia practitioners. The occurrence of PONV related to anesthesia and surgery prolongs hospital stays and increases healthcare costs. Protracted recovery times place constraints on patients, healthcare systems, and healthcare financiers. Many pharmacological antiemetics have been developed and are in use in the attempt to alleviate PONV. Side effects and cost profiles of many of these interventions, however, reinforce the broadly held belief that there remains opportunity for improvement. Because the Western culture almost exclusively favors evidence-based scientific practice and interventions, the search continues for an ideal, cost-effective, safe, and efficacious pharmacological agent to prevent PONV. Eastern culture, on the other hand, relies heavily on naturopathic remedies whose successful use has spanned thousands of years. Increasing attention has been given to the potential benefits of nonpharmacological intervention for the prevention of PONV in association with anesthesia care. Therefore, the purpose of this AANA Journal course will be to focus attention on what is known and what is unknown in the literature regarding use of the nonallopathic remedy of acupressure as a nonpharmacological alternative to commonly utilized antiemetic prophylaxis.     

Oncology and physical medicine and rehabilitation

IntroductionCancer patients are living longer with deficiencies and functional impairments requiring often typically a care in physical medicine and rehabilitation (PMR).ObjectiveTo examine the care of cancer patients in PMR.MethodInvestigation made with a questionnaire diffused from the e-mail listing of the Société Française de Médecine Physique et de Réadaptation.ResultsSixty-seven answers received. Fifty-seven centers take care of cancer patients. On average, 4% of cancer patients are hospitalised in PMR. Spinal cord injuries and hemiplegias are the most common impairments. Forty-two percent of the PMR units take the patients in all the stages of cancer treatment. Working relationships between PMR and oncology units are formalized only eight times out of 52. In case of health degradation, relationships with a palliative care unit are frequent but not generalized. Eighty-five percent of the centers think that PMR is not enough developed in oncology.ConclusionsIn spite of its limited character, this investigation shows that the PMR units take these patients. Situations where PMR has an important role in the follow-up of cancer patients are multiple and publications have showed its interest, especially on the limitations of activities. It is important to make better known the interest of PMR in oncology units but also to develop specific care within PMR units.
