A total of 872 children aged up to 14 years, who were diagnosed withleukemia in Greece during the decade 1980-89, were allocated by place ofresidence to the 601 administrative districts of the country. Evaluation ofspatial clustering was done using the Potthoff-Whittinghill method, whichvalidly assesses heterogeneity of leukemia risk among districts with variableexpected numbers of cases. There was highly significant evidence for spatialclustering occurring particularly among children living in urban and, to alesser extent, semi-urban areas. The evidence was stronger for childrenyounger than 10 years old, applied also to children in different five-yearage groups, and persisted when cases of acute lymphoblastic leukemia wereanalyzed separately. These findings provide support to the hypothesis thatlocalized environmental exposures could contribute to the etiology ofchildhood leukemia, but they cannot distinguish between exposures of physicalor chemical nature, nor can they exclude socially conditioned patterns ofexposure to infectious agents. 相似文献

Psoas abscess in children, and especially in neonates, is an uncommon condition which is difficult to diagnose clinically.
The US, CT and MR findings of a psoas abscess in a neonate, which extended to the thigh, are reported. Imaging was helpful
in revealing the abnormality, in demonstrating its extension and in determining its nature. The child was treated conservatively
and the abscess resolved, leaving atrophy of the psoas muscle.

Single-incision approach in robotic gynecology is a relatively new concept. The role of single-port systems in robotic hysterectomy, their advantages and disadvantages, as well as the technical challenges, are still under investigation. A systematic review was performed by searching in PubMed and Scopus databases. In 810 out of 1225 patients, hysterectomy was performed for non-neoplastic disease. Single-Site® was the most common port system. Duration of the procedure and relative blood loss ranged from 60 to 311 min and 7 to 750 ml, respectively. The weight of the removed uteri ranged from 39 to 520 g. 4.9% of the included patients presented complications, among which bleeding, vaginal haematoma, laceration and dehiscence, umbilical hernia, and visceral injuries. Conversion rate to laparotomy reached 2.8%. Although some technical difficulties are still described in the literature, the single-port approach is becoming more standardized nowadays and performed by more surgeons. The initial phase of the learning curve can be achieved after five cases, while a proficiency in intracorporeal cuff suturing after 14 cases. Uterus weight and previous abdominal surgical history can still be limitations of the technique. Compared to our previous study, we can see that the technique has been used in more elderly or obese patients. The complication rate can reach 4.9% while the conversion rate can reach 2.8%. However, we consider that complication and conversion rates as well as surgical time could be improved with experience. Regarding post-operative pain and cosmetic outcomes, the lack of information do not allow us to draw any safe conclusions. 相似文献

Problem: Medical students have limited exposure to Geriatrics in their traditional training. Service-learning offers students the opportunity to engage with older adult communities and become more comfortable interacting with this population. Intervention: A preclinical elective course was developed to expand medical students' experiences in Geriatrics through service-learning. In this course, students conducted needs assessments in diverse older adult communities, created health education projects to address community-identified needs, and reflected on their experiences through written assignments and presentations. The course instructor presented lectures on special topics in Geriatrics, including ageism and health literacy. The curriculum aimed to familiarize students with older adults' needs in a variety of settings. Context: Over 3 years, 74 students participated in the service-learning course. Students were assigned to older adult community sites, where they conducted needs assessments and designed and implemented original educational projects targeting community concerns. Program evaluation methods included a validated survey assessing students' attitudes toward older adults, course evaluations, review of student assignments and projects, and feedback from older adult participants and site coordinators. Outcome: Students gained hands-on experience working with older adults and designing appropriate health education projects. Analysis of attitude surveys demonstrated students' increased interest in Geriatrics as a career. Both students and older adult participants described enjoyable, valuable experiences gained from service-learning activities. Lessons Learned: Students appreciated the combination of community and classroom learning about Geriatrics. Service-learning was most constructive at sites with responsive coordinators, engaged older adults, and a need for health education resources. The course challenged students to assess health needs in communities that included cognitively impaired elders and to design educational projects tailored to older adults. 相似文献

In this research, we examined the application of thymol-based powder, directly over the top of the brood frames in colonies with different population in a 2-year study. The efficacy against mites, the side effects on bees and the contamination of honey were studied comparably to thymol-based gel treatment. In one-store colonies, thymol-based powder treatment gave average efficacy 64.5 % and did not differ significantly from thymol-based gel treatment (65.4 %). The natural mortality in control colonies was 41.4 % and the corrected efficacy (E T) during 2 years was 39.4 and 40.9 %, respectively. In two-store bee colonies, the application of thymol-based powder on top of each hive body gave higher E T (45,4 %) than on top of the double body hive (40.4 %), without statistically significant differences. The average concentration of thymol residues in honey 24 days after the application was 368 and 1,119 μg kg?1 for the honey of colonies treated with thymol-based powder and thymol-base gel, respectively. 相似文献
