Short communication: treatment of relapsing-remitting multiple sclerosis 96 patients with IFN-beta1b: results of a 6-year follow-up.

The first pharmacon with proved efficacy for the treatment of patients with the relapsing-remitting or relapsing-progressive form of multiple sclerosis (MS) was interferon-beta1b (IFN-beta1b). In 1996, we started treating 34 relapsing-remitting (RRMS) and 2 relapsing-progressive MS (RPMS) patients with IFN-beta1b. Of these 36 patients, 28 received continuous medication for 6 years. The primary end point of the study was the effect of 6 years of continuous IFN-beta1b treatment on the annual relapse rate, the secondary end point was the change in the progression index during the 6 years, and the tertiary end point was the alteration in the expanded disability status scale (EDSS) score of the patients. Finally, we give the reasons for the dropouts. The relapse rate decreased by 80.62% (p < 0.001), the mean EDSS score increased significantly, by approximately 0.5 points, to 2.21 +/- 1.48 (p = 0.016), and the reduction in the mean progression index was 67.19% (p < 0.001). This increase of < 0.5 point in the EDSS score is appreciably different from the 3-point deterioration expected after 6 years for the natural course of the disease. The significant improvement in the progression index clearly demonstrates that 6 years of IFN-beta1b therapy slowed the progression of the disease, thereby improving the quality of life of these MS patients.     

The primary motor and premotor areas of the human cerebral cortex.

Brodmann's cytoarchitectonic map of the human cortex designates area 4 as cortex in the anterior bank of the precentral sulcus and area 6 as cortex encompassing the precentral gyrus and the posterior portion of the superior frontal gyrus on both the lateral and medial surfaces of the brain. More than 70 years ago, Fulton proposed a functional distinction between these two areas, coining the terms primary motor area for cortex in Brodmann area 4 and premotor area for cortex in Brodmann area 6. The parcellation of the cortical motor system has subsequently become more complex. Several nonprimary motor areas have been identified in the brain of the macaque monkey, and associations between anatomy and function in the human brain are being tested continuously using brain mapping techniques. In the present review, the authors discuss the unique properties of the primary motor area (M1), the dorsal portion of the premotor cortex (PMd), and the ventral portion of the premotor cortex (PMv). They end this review by discussing how the premotor areas influence M1.     

Implementing and complying with the Smoke-free Hospitals Project in Catalonia, Spain.

The objective of the study was to describe the implementation of measures for preventing tobacco consumption developed in the Catalan Network of Smoke-free Hospitals. Information from 25 hospitals that are actively involved in the Catalan Network of Smoke-free Hospitals (April 2004) was used. The degree of implementation of the Smoke-free Hospitals Project was analysed by means of the Self-Audit Questionnaire of the European Network for Smoke-free Hospitals; each hospital was analysed globally and according to the duration of its Network membership (<1 year: implementation stage; > or =1 year: consolidation stage). In terms of global indicators, there were high levels of commitment (64.8%), communication (74.7%), tobacco control (77.4%) and implementation of smoke-free environments (81.0%). A lower degree of implementation (<50%) was found in education and training, health promotion and healthy workplaces. According to the duration of Network membership, significant differences were observed for communication, environment, healthy workplaces and follow-up. Deficits were observed in areas such as specialist training and cessation support, and further input is required here. By identifying areas needing attention, providing a guide for policy development and by administering it periodically, one can ensure that progress is kept on track.     

Constipation in the population over 50 years of age in Albacete province.

OBJECTIVE: To Determine the incidence of constipation in Albacete province and its relation with diet and lifestyle. PATIENTS AND METHODS: Cross-sectional population survey. We studied 414 participants over 50 years of age in Albacete province. 445 persons over 50 years of age were included in the study. All participants were selected by systematic random sampling; 414 participants filled in the questionnaire correctly. Main measures: age, weight and height, marital status, level of education and occupation; presence of a disease, number of sleep hours a day, physical exercise, smoking, alcohol intake, drug intake (anti-inflammatories and laxatives); bowel habit, diet, meal frequency and place; food intake frequency per week, daily intake of water, coffee, tea and herbal beverages; vitamin and fiber supplements; presence of cancer in the family. RESULTS: 56.9% of participants were women. Mean age 67.07 years. In Albacete province, 4.4% of the population over 50 years have a bowel habit consistent with constipation. Most participants had three meals a day (breakfast, lunch, and supper), while 50% had another meal in the morning or afternoon. These meals took place, habitually, in the domicile. There was a preponderance in daily intake of the following foods: milk (83.7%), bread (95.1%), vegetables (68.8%), fruit (91.8%), and virgin olive oil (96.6%). Fish was eaten every one to two days, and pulses and meat every three to six days. 44.4% of participants drank one to two liters of water a day. Only 3.9% of participants took some supplement; 35% of participants were on a diet. It was observed that 97.7% of participants with more than three defecations a week had a high intake of virgin olive oil; 65.7% of participants did some physical exercise customarily; 70.2% of participants were non-smokers, 10.2% were smokers, and 18.4% were ex-smokers. With regard to alcohol, the percentage of drinkers was 35.1%. The main class of medications taken by participants was NSAIDs - 14.5%; 79.7% took neither NSAIDs nor laxatives. Only 2.7% of participants took laxatives regularly. CONCLUSIONS: Most participants had relatively healthy eating habits.     

Endothelial dysfunction as a common link between erectile dysfunction and cardiovascular disease

Erectile dysfunction (ED) is often not considered in the same context as such traditional cardiovascular conditions as hypertension, dyslipidemia, diabetes, or ischemic heart disease. The detection of ED might be one of the most powerful tools to help manage cardiovascular disease in men. Clinical research suggests that the penile vascular bed is a sensitive indicator of early systemic endothelial cell or smooth muscle dysfunction. ED could be one of the initial signs of oxidative stress that occurs before the development of the structural, occlusive cardiovascular disease. ED is becoming a barometer of overall global cardiovascular risk and should be viewed in this context rather than as “just a problem with the penis.” Asking men about ED as part of the review of systems is an effective means of practicing preventive vascular medicine.

The association of cancer survival with four socioeconomic indicators: a longitudinal study of the older population of England and Wales 1981–2000

Background  

Many studies have found socioeconomic differentials in cancer survival. Previous studies have generally demonstrated poorer cancer survival with decreasing socioeconomic status but mostly used only ecological measures of status and analytical methods estimating simple survival. This study investigate socio-economic differentials in cancer survival using four indicators of socioeconomic status; three individual and one ecological. It uses a relative survival method which gives a measure of excess mortality due to cancer.     

Efficacy of diphenhydramine against cough in humans: a review

Aim To determine the efficacy of diphenhydramine against cough due to respiratory infection or irritation in patients/subjects without comorbidities. Method Two reviewers independently identified English language studies, searching on: clinical trials, randomized, diphenhydramine (OR dimenhydrinate), antitussive agents, cough (combine using AND). Sources were: Medline (1966–2005), Embase (1980–2005), Cochrane and references from retrieved articles. Two other reviewers, blinded to study origin selected studies, inclusion criteria being: diphenhydramine monotherapy against placebo, double-blinded, randomized, clinical trial, intention-to-treat, dropout information. The blinded reviewers evaluated the selected studies on a quality scale. Results Eleven articles were identified, 7 were rejected (4 not placebo controlled, 2 had no diphenhydramine, 1 not blinded), leaving 4 articles, that were included in the evaluation and scored 20, 21, 25 and 26 out of a maximum of 32. In these selected studies, a total of 162 people were examined, 65 on diphenhydramine, 63 on placebo and 34 in a crossover setting. There was a total of 13 dropouts. The crossover studies demonstrated significant effect; 27–56% reduction in 20 healthy volunteers and 21–26% reduction in 13 patients (originally 14, one outlier left out), whereas the active versus placebo studies did not. Conclusion In spite of the 60 years that the substance has been on the market, only few studies have properly evaluated the effect of diphenhydramine against cough. Presumptions about efficacy of diphenhydramine against cough in humans are not univocally substantiated in literature.
