Urolithiasis in Jordanian children. A report of 52 cases 总被引:3,自引:0,他引:3
Fifty-two children with urinary calculi seen between 1975 and 1986 were reviewed. Males dominated the series. The age distribution ranged from 10 months to 14 years (mean 7.2 years); 71% presented after school age. Most patients had upper tract stones. The main presenting symptoms were abdominal pain, infection and haematuria. The causative factors or co-factors were infection, malformations and urodynamic abnormalities. Metabolic disorders were rare. Calcium oxalate and uric acid stones were found most often. Surgical management was required in 88% of patients and only 3.8% had a recurrence. Presenting symptoms are variable and so a high index of suspicion is required for diagnosis. 相似文献

This report describes a patient with an implantable defibrillator who suffered an inappropriate defibrillation shock upon retrieving some food items from his inadequately earthed refrigerator. Noise typical of electrical interference can be observed in the stored electrogram of the episode. The patient was instructed to earth his home appliances, but he decided to avoid his refrigerator altogether, and has had no subsequent shocks. 相似文献

The use of computer assisted learning (CAL) in the medical undergraduate curriculum is increasing. Little is known regarding the acceptability of CAL among medical students. The present study was conducted to investigate the possible anxiety generated by and the acceptability of CAL among medical students. One hundred and twenty-six students completed a questionnaire after using n software package which has been written as an adjunct in teaching urology. The present study demonstrates that there was little anxiety experienced by the students when using CAL and furthermore that there was a high level of acceptance for this type of instruction. This is encouraging for medical educators involved in producing multimedia packages for teaching medicine and surgery. 相似文献

Nitrate-rich food can increase nitric oxide production and improve vascular and brain functions. This study examines the feasibility of a randomised controlled trial (RCT) testing the effects of prolonged consumption of different doses of dietary nitrate (NO3−) in the form of beetroot juice (BJ) in overweight and obese older participants. A single-blind, four-arm parallel pilot RCT was conducted in 62 overweight and obese (30.4 ± 4 kg/m2) older participants (mean ± standard deviation (SD), 66 ± 4 years). Participants were randomized to: (1) high-NO3− (HN: 2 × 70 mL BJ/day) (2) medium-NO3− (MN: 70 mL BJ/day), (3) low-NO3− (LN: 70 mL BJ on alternate days) or (4) Placebo (PL: 70 mL of NO3−-depleted BJ on alternate days), for 13 weeks. Compliance was checked by a daily log of consumed BJ, NO3− intake, and by measuring NO3− and NO2− concentrations in plasma, saliva, and urine samples. Fifty participants completed the study. Self-reported compliance to the interventions was >90%. There were significant positive linear relationships between NO3− dose and the increase in plasma and urinary NO3− concentration (R2 = 0.71, p < 0.001 and R2 = 0.46 p < 0.001, respectively), but relationships between NO3− dose and changes in salivary NO3− and NO2− were non-linear (R2 = 0.35, p = 0.002 and R2 = 0.23, p = 0.007, respectively). The results confirm the feasibility of prolonged BJ supplementation in older overweight and obese adults. 相似文献

Observations of the epizootic of bovine ephemeral fever which occurred in Saudi Arabia during 1996 are presented. The investigations included the collection of epidemiological data from affected farms and the testing of sera for antibodies to the virus. The authors report a mean morbidity rate of 50% and a mean case fatality rate of 0.3%. Of the infected cattle, 4% were affected by recumbency, the majority of these recovered (89%). The clinical signs observed in affected cattle were uniform throughout the region concerned. The features of the outbreak, obtained through field investigations, were considered in relation to the ecological and meteorological conditions which were prevalent at the time. The outbreak occurred during the summer months (May to October) in the central and eastern regions of Saudi Arabia, with the initial infection reported at the Al-Ahsa oasis. Farms which were subsequently affected were all reported to possess areas of stagnant water suitable for the reproduction of the vectors of the disease (Culicoides spp. and mosquitoes). To conclude, the authors discuss precautions to prevent future outbreaks of bovine ephemeral fever in Saudi Arabia. 相似文献

In this paper, we review the literature to date on technical competence in surgeons; how it can be defined, taught to trainees and assessed. We also examine how we can predict which candidates for surgical training will most likely develop technical competence. While technical competency is just one aspect of what makes a good surgeon, we have recognized a need to review the literature in this area and to combine this with broader definitions of competency. Our review found that several methods are available to objectively measure, assess and predict technical competence and should be used in surgical training. 相似文献

To study the prevalence of Type 2 Diabetes Mellitus (T2DM) in a population of United Arab Emirates (UAE) residents through the creation of the ??Emirates Family Registry?? (EFR). Major hospitals and diabetes centres in the UAE were contacted to establish a bio-banking facility referred to as the EFR. Through assistance made available by the Ministry of Health and collaborators of this network, demographic data of T2DM patients were collected and collated in a database for analysis and longitudinal studies. Clinical specimens were collected for biochemical profiling (such as; glucose, lipids, HbA1c levels). In the first 24?months of the operation the EFR recruited 23,064 adult volunteers from three major hospitals and nine primary care centres throughout the UAE. Within this cohort, 88% were patients classified as T2DM patients from the medical records. The cohort was divided into age categories with 59% of T2DM patients aged between 40 and 59?years old. UAE nationals comprised 30% of the database of which 21% were diagnosed with T2DM. However the percentage of adults with T2DM was higher in other ethnic groups effecting almost 33% of the Indians who live in the UAE. A total of 741 UAE Nationals consented to donate blood; in phase I of the study; for biochemical testing after which 23% were diagnosed with T2DM, 30% with pre-T2DM and 47% were healthy. This study is consistent with the previously reported high prevalence of T2DM in the UAE. Furthermore, analyses of the factors that predispose to the disease have revealed that obesity, a large waist circumference, consanguineous marriage, family history, lack of physical activity, unhealthy dietary practices, high total cholesterol, and high triglycerides levels were more prevalent in T2DM patients. The classification of these features will contribute to defining more effective and specific plans to screen for and manage diabetes and its complications in UAE and other developing countries. 相似文献

Modern medical simulation technology (MST) debuted in 1960 with the development of Resusci Annie (Laerdal 2007), which assisted students in the acquisition of proper ventilation and compression techniques used during basic life support. Following a steady stream of subsequent technological advances and innovations, MST manufacturers are now able to offer training aids capable of facilitating innovative learning in such diverse areas as human patient simulators, simulated clinical environments, virtual procedure stations, virtual medical environments, electronic tutors, and performance recording. The authors list a number of the most popular MSTs presently available while citing evaluative efforts undertaken to date regarding the efficacy of MST to the medical profession. They conclude by proposing a variety of simulation innovations of prospective interest to both medical and technology personnel while offering healthcare administrators a series of recommended considerations when planning to integrate MST into existing medical systems. 相似文献
