Fabian M. Laage Gaupp Nadia Solomon Ivan Rukundo Azza A. Naif Erick M. Mbuguje Anish Gonchigar Minzhi Xing John D. Prologo Douglas D. Silin Frank J. Minja 《Journal of vascular and interventional radiology : JVIR》2019,30(12):2036-2040
Despite a population of nearly 60 million, there is currently not a single interventional radiologist in Tanzania. Based on an Interventional Radiology (IR) Readiness Assessment, the key obstacles to establishing IR in Tanzania are the lack of training opportunities and limited availability of disposable equipment. An IR training program was designed and initiated, which relies on US-based volunteer teams of IR physicians, nurses, and technologists to locally train radiology residents, nurses, and technologists. Preliminary results support this strategy for addressing the lack of training opportunities and provide a model for introducing IR to other resource-limited settings. 相似文献

Background:Most abnormal parathyroid glands can be removed through a standard cervical incision; even those in the superior mediastinum. Those located in certain areas of the mediastinum, for example posteriorly or in the aortopulmonic window, historically have required excision through a median sternotomy or thoracotomy. Angioablation is a nonsurgical alternative to management of these lesions.Study Design:We present two case reports of mediastinal parathyroid adenomas that were excised thoracoscopically, and review the literature regarding the management of mediastinal parathyroid adenomas.Results:Both patients who underwent precise localization and thoracoscopic excision of their mediastinal parathyroid adenomas had resolution of their hypercalcemia with minimal associated morbidity and shortened recovery periods.Conclusions:We suggest that thoracoscopic excision of mediastinal parathyroid adenomas is the better means of controlling hypercalcemia secondary to parathyroid adenoma in those patients considered for either median sternotomy, thoracotomy or angiographic ablation where the exact location of the lesion can be established preoperatively. 相似文献

Neuropsychologic symptoms in the migraine syndrome 总被引:1,自引:0,他引:1
Twenty patients with complex neuropsychologic symptoms associated with classic migraine were selected from a group of 200 patients with vascular headache. Twenty types of symptoms were found and grouped into six categories (language, visual symptoms, cognitive-dysmnesic symptoms, olfactory-gustatory hallucinations, automatisms, and somatosensory symptoms). Some of the symptoms found have apparently not been reported previously. The importance of the analysis of this complex neuropsychologic set of symptoms and of the possible consequences of complicated, frequent vascular headache is emphasized. 相似文献

Background
In Uganda the prevalence of HIV averages 12% as was reported to the STD/AIDS control surveillance unit. In Uganda there are approximately 30,000 HIV infected infants per year. The burden of HIV disease is high in Uganda and patients present with ocular complications. However, there is paucity of information and knowledge concerning ocular manifestations in the paediatric HIV/AIDS population and how they may differ from those of adults.Objectives
To describe the ocular manifestations of HIV/AIDS infection in an African paediatric population. Generally the study will record the external ocular manifestations seen but specifically to document the intra-ocular lesions, in particular the retinal changes associated with paediatric HIV/AIDS.Design
A cross-sectional hospital based study.Setting
The study was conducted at the Paediatric Infectious Disease Clinic at Upper Mulago Hospital, in Kampala, Uganda.Patients
Patients are those with positive HIV sero status, with or without symptoms and signs of AIDS.Parents/caretakers of the children were interviewed to obtain the socio-demographic data of the patients and a general physical as well as an ophthalmic examination were conducted to document any ocular problems.Results
A total of 158 HIV -infected children were examined. The overall rate of ophthalmic involvement was 35%. The most common finding was a non-purulent conjuctivitis, observed in 12% of the patients, followed by perivasculitis of the peripheral retinal vessels, in 12 % of patients and molluscum contagiosum. 相似文献6.
DNA restriction fragment length polymorphism differentiates crossed from independent infections in nosocomial Xanthomonas maltophilia bacteremia. 下载免费PDF全文

Restriction fragment length polymorphisms of total DNA and rDNA were used to study the relationship between 11 isolates of Xanthomonas maltophilia, obtained from seven patients with nosocomial bacteremia in four distinct wards of a single hospital, and the type strain of the species, ATCC 13637. Our results indicated that there were episodes of cross-infection among the patients of two wards, but there were also independent infectious episodes in the two other wards. 相似文献

Evidence for the genetic unrelatedness of nosocomial vancomycin-resistant Enterococcus faecium strains in a pediatric hospital. 总被引:2,自引:0,他引:2 下载免费PDF全文

Vancomycin-resistant enterococci are now found with increasing frequency. Up to now, epidemiological studies of enterococci have been limited by the lack of convenient and accessible methods for comparing strains. In this study, we report an epidemiological investigation on 16 nosocomial vancomycin-resistant Enterococcus faecium strains isolated from 15 patients in four different wards of a children's hospital over a period of 17 months. Analysis of restriction fragment length polymorphism (RFLP) of total DNA and of ribosomal DNA regions (ribotyping) was used as a typing approach. Each strain produced a different total DNA RFLP pattern after HindIII and PvuII digestion, except for two strains that were isolated from a single patient and that gave indistinguishable patterns. In our system, ribotyping was less discriminative than RFLP of total DNA. This approach, therefore, shows the genetic unrelatedness of the nosocomial strains studied and excludes patient-to-patient strain transmission either in the same ward or between wards. 相似文献

Cystic fibrosis screening: a fetus with hyperechogenic bowel may be the index case. 总被引:1,自引:1,他引:1 下载免费PDF全文

BACKGROUND: The potential of hyperechogenic fetal bowel to act as a hallmark for prenatal cystic fibrosis screening in the general population is controversial. METHODS: Our goal was to evaluate the incidence of cystic fibrosis in 209 fetuses with hyperechogenic bowel diagnosed at routine ultrasonography and with no family history of cystic fibrosis. The diagnosis of cystic fibrosis was based on prenatal screening for the eight mutations most frequently observed in France (deltaF508, deltaI507, 1717-1G-->A, G542X, G551D, R553X, W1282X, N1303K) and at postnatal follow up. RESULTS: The overall incidence of cystic fibrosis was 7/209 (3.3%) which is 84 times the estimated risk of CF in the general population (112500). Of these seven cases, six were diagnosed prenatally based on DNA analysis (deltaF508/deltaF508, n=5; deltaF508/G542X, n=1). One case in which only one mutation had been recognised was diagnosed clinically after birth (deltaF508/unidentified mutation). Of the seven cases, none was diagnosed at 16-19 weeks, four at 16-24 weeks, and three after this. The incidence of heterozygous fetuses (15/209, 7%) was not significantly higher than the 5% expected in the general population. The mutations involved in these heterozygous cases were deltaF508 (n=13), G542X (n=1), and G551D (n=1). CONCLUSIONS: Screening for cystic fibrosis should be offered to families in which fetal hyperechogenic bowel is diagnosed at routine ultrasonography. This underlines the need to review genetic counselling in this situation where the fetus is the index case for a genetic disease. 相似文献

Thyroidectomy is the most frequent procedure in endocrine surgery. The conventional approach through a collar incision, as described by Kocher in XIXth century, has become the “gold standard”. It is continuously evolving in spite of, many years ago, it showed to be safe and efficient with quality standards difficult to beat.Endoscopic and robotic surgery have developed “new approaches” to thyroid in order to improve the cosmetic results, looking even for invisible scars.We have done a thoughtful review of most of them trying to understand their benefits and drawbacks.Currently none of these “new approaches” have been shown to be better than conventional open thyroidectomy beyond offering a better cosmetic result. Besides, only a small percentage of patients can benefit of them. However, most of these approaches will remain if they treat the diseased thyroid and also improve the quality of life of our patients. 相似文献
