Evaluación formativa mediante el portafolio de 4 promociones de residentes de medicina de familia y comunitaria de la Unidad Docente de Murcia

ObjectiveTo evaluate the performance and quality of the 10 groups of training tasks envisaged in the portfolio training model undertaken by all residents of the Primary Care Teaching Unit in Murcia.DesignA cross-sectional study was conducted on the portfolios provided and completed by all residents in May 2011.ParticipantsAll residents who were in training at that time (131).MethodTen groups of training tasks were established from those recommended by the National Commission for the specialty. The performance of each one in each of the portfolios was evaluated, and the compliance for each training task was calculated. The quality of the performance of each of the tasks was given a score, 0 points (very poor) to 10 points (excellent).ResultsAs regards compliance, the tasks that were most performed were: filling in the Resident book correctly and using the resident skills guide, both with 99.24%, followed by reflection reports on the training visits. All tasks had a compliance rate higher than 67%. The mean percentage of compliance was 86.49%. All tasks obtained an average score greater than 7 (outstanding). The overall mean score was 7,8 points.ConclusionsThe level of perfomance of the tasks set out in the portfolio by the residents was very satisfying. It is necessary to continue working on improving the performance of the portfolio.     

Biosutures improve healing of experimental weak colonic anastomoses

Purpose  

Use of biosutures in animal models of colonic anastomoses is associated with decreased adhesions without affecting anastomotic strength. This study aimed to evaluate the effect of biosutures on colonic anastomoses kept free of adhesions by peritoneal instillation of icodextrin 4%.     

Effect of different doses of hexavalent chromium on mandibular growth and tooth eruption in juvenile Wistar rats

Not only workers employed at industrial plants are exposed to intoxication with the element they manipulate, the population at large is also at risk of suffering health problems caused by contaminating wastes inadequately treated for their safe disposal. As a result certain toxic substances, such as hexavalent chromium,has reached the general population including children. The present study sought to evaluate the effect of intoxication with hexavalent chromium on body and mandibular growth and tooth eruption in suckling Wistar rats. Potassium dichromate was administered by gavage in a dose of 6.25 or 12.5 mg/kg body weight (b.w.) to one of the two groups of 4-day-old Wistar rats during 10 days. Our results showed that the effects of chromium are dose-dependent. Morphometric studies of body growth showed lower body weight in both experimental groups and shorter tail length in animals receiving 12.5 mg/kg b.w. dose of chromium, compared with controls. All parameters of mandibular growth were lower in the experimental group receiving 12.5 mg/kg b.w. of chromium. Differences in tooth eruption were observed at the level of the first molar in animals receiving 12.5 mg/kg and of the second molar in those receiving 6.25 mg/kg b.w. of chromium. Chromium was found to affect all the studied parameters.     

Gallstones are associated with carotid atherosclerosis

Background/Aims: Gallstone disease (GD) and cardiovascular disease (CD) are common diseases worldwide with considerable economical impact and they are strongly associated. Carotid atherosclerosis is an excellent marker of risk for CD like stroke and myocardial infarction. The aim of this study was to assess the association between gallstones and carotid atherosclerosis. Methods: A cross‐sectional study was conducted. We evaluated subjects with ultrasonographical evidence of GD and asymptomatic subjects without such evidence. Anthropometric, clinical and biochemical variables were collected. The Metabolic syndrome was evaluated using adult treatment panel III criteria. Carotid artery intima–media thickness (CIMT) was determined by a standard ultrasound protocol. Insulin‐like growth factor‐1 (IGF‐1) serum levels were measured in all subjects. Results: We studied 191 subjects: 62 subjects with GD (53.2% males) and 129 asymptomatic subjects without GD (65.9% males). Subjects with GD exhibited a higher body mass index, body fat percent, insulin serum levels and CIMT (P<0.05 for all). The prevalence of GD was higher in subjects with a CIMT>0.75 independently of other factors [odds ratio (OR) 2.12, 95% confidence interval (CI) 1.04–4.34; P=0.039], and for every 0.1 mm increase in CIMT the independent probability to be a case of GD increased by a factor of 1.25 (95% CI 1.02–1.53; P=0.027). IGF‐1 levels did not differ among groups. Conclusions: Subjects with GD exhibit greater carotid atherosclerosis, and therefore have a higher risk for stroke and myocardial infarction.     

Heart-hand syndrome

Heart–hand syndromes show substantial clinical and genetic heterogeneity. The unusual case of a patient with a heart–hand syndrome consisting of preaxial polydactylia, postaxial syndactylia, parachute mitral valve, mild subaortic stenosis, and double outlet right ventricle is presented and discussed. The importance of distinguishing Holt–Oram syndrome from its phenocopies and other heart–hand syndromes is underlined.     

Unsafe Drug Use and Arrhythmic Events in Brugada Patients with ICD: Results of a Long-Term Follow-Up

Purpose

Brugada syndrome is a hereditary disease linked with an increased risk of sudden death that may require an implantable cardioverter-defibrillator (ICD) in order to halt the arrhythmic events. The aim of this study was to identify possible triggers for appropriate ICD therapies in patients with Brugada syndrome, focusing on their past and current therapeutic profiles.

Methods

Thirty patients with high-risk Brugada syndrome, with ICD implanted at the Coimbra Hospital and University Center, were enrolled. Patients were questioned about their Brugada syndrome history, previous cardiac events, comorbidities, present and past medications, and physical activity. Patients were followed up during 5.8?±?5.3 years. The ICD was interrogated, and arrhythmic events and device therapies were recorded. The cohort who received appropriate ICD therapies was compared with the remaining patients to determine the potential link between clinical variables and potentially fatal arrhythmic events.

Results

More than half of the patients (53.3%) took at least one non-recommended drug, and 16.7% received appropriate ICD therapies, with a long-term rate of 4.0%/year. There was a tendency for more appropriate ICD therapies in patients who took unsafe drugs (85.7 versus 45.5%, p?=?0.062), and the mean time between unsafe drug intake and appropriate ICD therapies was 3.8?±?7.5 days.

Conclusions

This study revealed that the medical community is still unaware of the pharmacological restrictions imposed by Brugada syndrome. Patients who took non-recommended drugs seem to have a higher risk of ventricular arrhythmic events.
