CTX-M-131 is a natural Asp240Gly variant from the CTX-M-2 group detected in a Providencia rettgeri clinical strain from Brazil. Molecular analysis showed that blaCTX-M-131 was inserted in a complex class 1 integron harbored by a 112-kb plasmid, which has not been previously described as a platform for CTX-M-encoding genes with the Asp240Gly mutation. Steady-state kinetic parameters showed that the enzyme has a typical cefotaximase catalytic profile and an enhanced activity against ceftazidime. 相似文献

To evaluate information preferences and information seeking behaviour in ALS patients and caregivers. Sixty ALS patients and caregivers couples were interviewed using a structured questionnaire about the content of diagnosis communication and their information seeking behaviour. The patients (35 men and 25 women) had a mean age of 63.4 years (SD 9.5). The caregivers (21 men and 39 women) had a mean age of 53.3 years (SD 14.9). The overall satisfaction with bad news communication and the impression that the physician had understood their feelings were higher amongst patients. Both parties indicated that the most important aspects to be informed were current researches, disease-modifying therapies and ALS outcome. Approximately 55% of patients and 83.3% of caregivers searched for information from sources outside the healthcare system. The most frequently checked source was internet, although its reliability was rated low. The caring neurologist should better attune the content of communication to patients' and caregivers' preferences, trying to understand what they want to know and encouraging them to make precise questions. Health professionals should be aware that ALS patients and caregivers often use internet to obtain information and should help them to better sort-out and interpret the news they found. 相似文献

Leprosy is one of the most common treatable causes of neuropathy in the world. Peripheral nerves and skin are commonly affected. We reported the clinical features and electrophysiological findings in 46 patients with leprosy. The aim of our study was to evaluate the nature of damage in the nerve fibres, especially in the first phase of disease. Forty‐six patients (mean age: 44.8 ± 17.8) with diagnosed leprosy were studied by neurological examination and nerve conduction studies (NCS). Twenty‐eight patients were examined for a mean period of 34.8 months. The number of tests for patients varied from 1 to 13 controls. Amplitude of sensory and motor action potentials (SNAP and MAP), sensory‐motor conduction velocity of median, ulnar, tibialis, peroneal and sural nerves were evaluated. Abnormalities were found in 282 of 647 nerves investigated (37.56%), sensory nerve abnormalities being more frequent than motor (50.16% 29.45). Of 282 nerves with neurophysiological abnormalities, 123 were clinically asymptomatic (43.62%). A statistically significant correlation between duration of disease and number of electrophysiological abnormalities was demonstrated. In 19 nerves partial "conduction‐block"(reduction of cMAP > 50% in the proximal response) was individuated. The first electrophysiological alteration, suggesting segmental demyelination, was detected in 41 nerves of 21 patients (33.3 %). According to this view, our data support the hypothesis that leprosy induces a neuropathy of demyelinating nature in the first phase. 相似文献

BACKGROUND: Enteral nutrition may be required in amyotrophic lateral sclerosis (ALS), and is usually achieved by percutaneous endoscopic gastrostomy (PEG). As PEG is not indicated in patients with severe respiratory impairment, an alternative is percutaneous radiological gastrostomy (PRG), involving air insufflation into the stomach under fluoroscopic guidance for tube insertion. OBJECTIVE: To evaluate the safety of PRG and its effect on survival and respiratory function in ALS patients with respiratory failure. METHODS: 25 consecutive ALS patients with severe dysphagia and forced vital capacity (FVC) <50% underwent PRG after October 2000. They were compared with 25 consecutive ALS patients with FVC <50% who underwent PEG before October 2000. Respiratory function was evaluated before and after the procedure. RESULTS: The two groups were similar for all relevant characteristics. PRG was successful in all cases, PEG in 23/25. One patient in each group died after the procedure. The mean survival time after the procedure was 204 days in the PRG group and 85 days in the PEG group (p<0.004). Respiratory function decreased more in the PEG group than in the PRG group (p<0.02). CONCLUSIONS: PRG appears to be safer than PEG in ALS patients with moderate or severe respiratory impairment, and is followed by a longer survival. 相似文献

The clinical and neurophysiologic data from 65 patients taking thalidomide were reviewed. Thalidomide sensory neurotoxicity was found to be cumulative dose dependent but occurs only when the total dose is relatively high (>20 g). The risk of developing sensory neuropathy is around 10% below this threshold but increases with higher doses. 相似文献

Laser photocoagulation treatment of occult choroidal neovascularization (CNV) in age related macular degeneration has been up to now discouraging. We report a randomized clinical trial comparing grid laser treatment versus the natural course in 24 eyes with this kind of neovascularization. In 12 eyes a low energy scatter photocoagulation was applied to the areas of presumed CNV and abnormal retinal pigment epithelium, sparing the fovea. The follow-up ranged from 1 to 3 years. At the three months follow-up visit, the subretinal exudation appeared reduced in 40% of the treated eyes and in none of the control eyes. During the period of follow-up the occult CNV turned to classic CNV in 4 treated and in 4 untreated eyes. At the last examination (average follow-up 18 months), anatomical and functional conditions were not significantly different in the two groups. Our data fail to show a beneficial long-term effect of grid laser treatment for occult CNV; no iatrogenic complications were seen in our series.Presented at the 3rd International Symposium on Ocular Circulation and Neovascularization, Paris, May 21–23, 1992. 相似文献

A multicenter survey, carried out in 2010 in Argentina, showed an increased prevalence of extended-spectrum β-lactamase (ESBL)-producing enterobacteria, with some changes in the molecular epidemiology of circulating ESBLs. While enzymes of the CTX-M-2 group remain endemic, the emergence of CTX-M-15 and of enzymes of the CTX-M-8 and CTX-M-9 groups was observed. The CTX-M-15-positive isolates represented 40% of CTX-M producers and included representatives of Escherichia coli ST131 and Klebsiella pneumoniae ST11. 相似文献
