Two spontaneous neurodegenerative diseases of the horse, equine motor neuron disease (EMND) and equine degenerative myeloencephalopathy (EDM), have been associated with -tocopherol deficiency, and both were characterized by prominent accumulations of endothelial lipopigment in the small vessels of the spinal cord. These endothelial pigment deposits appear to be reversible. In EMND horses pasture-supplemented for 9 months or more after the progression of weakness and wasting had arrested, there was very little endothelial lipopigment. The origin and the potential effects of these endothelial lipopigment accumulations are discussed.  相似文献

BACKGROUND: Camel collision accidents are a common occurrence in Saudi Arabia, with a high rate of mortality and morbidity. Isolated injuries are rare because of the nature of impact sustained by the person. CASE DESCRIPTION: A 4-year-old child with an isolated depressed skull fracture resulting from a camel collision is described. The other occupants of the car were crushed to death. The child sustained only an impact to his head, causing a compound depressed skull fracture with localized cortical damage. CONCLUSIONS: Camel collision accidents are a common cause of mortality and morbidity in Saudi Arabia. Isolated skull injuries are rare and result from a localized impact. This is the first report of a compound depressed skull fracture from such an incident. The extent of the problem and efforts toward prevention are described.  相似文献

From a total of 26,603 admissions to the paediatric wards, 1360 paediatric nosocomial urinary tract infections (PNUTI) were identified during a 5-year retrospective chart review at the SFGH. The ages ranged from 3 days to 13 years, with 46% boys and 54% girls. The highest rates of PNUTI per service per 100 admissions were seen in the nursery (11.28) followed by paediatric surgery (2.89) and paediatric medicine (2.86). Although the greatest number of PNUTI occurred in the nursery, comparison between the years was not statistically significant. About 90% (1218 of 1360) of PNUTI occurred in catheterized patients. No documentation was found specifying the type of catheterization (intermittent or continuous). About 90% (1210 of 1360) of isolates were single organisms with Escherichia coli, Proteus mirabilis, Klebsiella spp. and Group B streptococci accounting for a total of 70% of all pathogens. However, the composition of the most common isolate in each service differed. The most common isolate in the nursery was E. coli, in the paediatric medical and surgical services the most common isolates were Klebsiella spp. and Proteus mirabilis, respectively. Proteus mirabilis was isolated predominantly from boys with structural abnormality of the urethral tract. No PNUTIs were complicated by bacteraemia. The antibiotics with least effectiveness (in increasing order) for UTIs were cephalexin, ampicillin, trimethoprim, co-trimoxazole and tetracycline. The most effective antibiotics were nalidixic acid, gentamicin and amoxicillin-clavulanic acid.  相似文献

Following systemic administration of the noradrenaline (NA) neurotoxin, DSP4 (50 mg/kg), rats were found to be retarded in the rate at which they acquired the "right-turn" running response in a modified T-maze choice situation, as measured by the total number of errors per session and median latency to reach the goal box. Desipramine (DMI, 20 mg/kg), injected 30 min before DSP4 blocked the acquisition retardation. DSP4 was found to have a short-lasting effect upon spontaneous motor activity, while food and water intake recovery was complete within 7 days of the injection. Both the NA-accumulation data and endogenous NA concentrations indicated profound NA, but not 5-hydroxytryptamine (5-HT) and dopamine (DA), depletions in the cortex, hippocampus and cerebellum. These data seem to confirm the role of the locus coeruleus-noradrenaline (LC-NA) system in an instrumental learning situation.  相似文献

PURPOSE: Preclinical and clinical studies have demonstrated that inhibition of prenylation can radiosensitize cell lines with activation of Ras and produce clinical response in patients with cancer. The aim of this study was to determine the maximally tolerated dose of the dual farnesyltransferase and geranylgeranyltransferase I inhibitor L-778,123 in combination with radiotherapy for patients with locally advanced pancreatic cancer. EXPERIMENTAL DESIGN: L-778,123 was given by continuous intravenous infusion with concomitant radiotherapy to 59.4 Gy in standard fractions. Two L-778,123 dose levels were tested: 280 mg/m2/day over weeks 1, 2, 4, and 5 for dose level 1; and 560 mg/m2/day over weeks 1, 2, 4, 5, and 7 for dose level 2. RESULTS: There were no dose-limiting toxicities observed in the eight patients treated on dose level 1. Two of the four patients on dose level 2 experienced dose-limiting toxicities consisting of grade 3 diarrhea in one case and grade 3 gastrointestinal hemorrhage associated with grade 3 thrombocytopenia and neutropenia in the other case. Other common toxicities were mild neutropenia, dehydration, hyperglycemia, and nausea/vomiting. One patient on dose level 1 showed a partial response of 6 months in duration. Both reversible inhibition of HDJ2 farnesylation and radiosensitization of a study patient-derived cell line were demonstrated in the presence of L-778,123. K-RAS mutations were found in three of the four patients evaluated. CONCLUSIONS: The combination of L-778,123 and radiotherapy at dose level 1 showed acceptable toxicity in patients with locally advanced pancreatic cancer. Radiosensitization of a patient-derived pancreatic cancer cell line was observed.  相似文献

Objectives: To objectively evaluate the clinical and functional outcomes of cochlear implantation in an elderly population. Design: Retrospective comparative study. Setting: Neurotology unit at Manchester Royal Infirmary, a supraregional tertiary referral centre in collaboration with Adult Cochlear Implant Programme at The University of Manchester. Participants: All cochlear implant procedures (38) undertaken on post‐lingually deafened elderly patients (age range at the time of implantation 65–80 years, n = 34) in the period from 1989 to 2002. Main outcome measures: Medical and surgical outcomes. Audiological performance outcomes for isolated words, words in sentences in quiet and noise. Functional outcome measures used are self‐reported measures of the social, psychological and emotional aspects of quality of life, and the differences between expectations for functional outcomes and the realization of functional outcomes. They included expectation profiles, Glasgow Benefit inventory (GBI) and Glasgow Health Status Inventory Questionnaire (GHSI). Results: There was statistically significant improvement post‐implantation of both open and closed set test scores (P < 0.01). Eighty‐two percentage of patients were completely satisfied with their cochlear implants. Patients judged that implantation restored half the loss of quality of life that they had experienced as a result of severe‐profound deafness with a highly significant (P < 0.001) improvement in overall quality of life after implantation. The commonest post‐operative observation was transient mild pyrexia. Conclusions: The age of a cochlear implant candidate should not be a factor in the candidacy decision‐making process. The quality of life of our elderly recipients was significantly improved after cochlear implant.  相似文献

Background. The aim of the present study was to assess the cost/efficacy of the pleural tent procedure after upper lobectomy.

Methods. A prospective randomized analysis was performed on 50 patients submitted to upper lobectomy and divided into two groups: group 1 (25 patients) with pleural tent; group 2 (25 patients) without pleural tent.

Results. The univariate comparison between the two groups did not show any significant difference in terms of age, gender, spirometry, smoking history, chronic obstructive pulmonary disease index, side of tumor, arterial oxygen tension, arterial carbon dioxide tension, size and location of tumor, presence of pleural adhesions, length of the stapled parenchyma, and operative time. Pleural tent significantly reduced the days of postoperative air leak (1.2 versus 5.8, p = 0.01), chest tubes (5.4 versus 10.4, p = 0.01), and hospital stay (6.9 versus 10.8, p = 0.01). Moreover, no difference was noted between the two groups in terms of pleural effusion in the first postoperative 48 hours, need of postoperative blood transfusion, and occurrence of other complications.

Conclusions. Pleural tenting after upper lobectomy is a safe and effective procedure and its routine use is warranted.  相似文献
