Sonography is widely used for evaluation of hand and wrist lesions. The easy accessibility, cost‐effectiveness, and good diagnostic accuracy of sonography coupled with the numerous benefits of real‐time imaging make it desirable. The aim of this article is to describe the typical sonographic appearances of lesions in the hand and wrist that are encountered frequently in routine clinical practice, such as inflammatory arthropathies, tumors, traumatic injuries, foreign bodies, and nerve entrapment syndromes. Relevant anatomy, scanning methods, and recent developments in musculoskeletal sonography are also discussed. 相似文献

The aim of this study was to assess the frequency and genotypic diversity of carbapenemase-producing Enterobacteriaceae (CPE) in stool samples from patients attending a military hospital in Pakistan. Further aims included the identification of factors that might predispose to faecal carriage and evaluation of 2 chromogenic culture media: Brilliance CRE and chromID CARBA. Of 175 patients, 32 (18.3%) had faecal carriage of CPE and all produced NDM-1 carbapenemase. All of these 32 patients were detected using chromID CARBA compared with 20 patients (62.5%) detected using Brilliance CRE (P = 0.0015). Duration of hospitalization and treatment with co-amoxyclav were statistically associated with a higher likelihood of carriage of CPE (P ≤ 0.05). The majority of NDM-1–producing Enterobacteriaceae co-produced CTX-M-1 group extended spectrum β-lactamase, and one third produced armA-type methylase. NDM-1 carbapenemase was most commonly found amongst commensal types of Escherichia coli, especially phylogenetic group B1. 相似文献

Posterior reversible encephalopathy syndrome (PRES) is a rare complication of nephrotic syndrome and corticosteroid therapy.
Here, we discuss an 18 year old man with type 1 membranoproliferative glomerulonephritis (MPGN) secondary to hepatitis B infection
who developed posterior leukoencephalopathy while on therapy with lamivudine and prednisone. He developed seizures and vision
loss. He also had hypertension, but no sudden elevation was recorded at any time. Magnetic resonance imaging revealed patchy
areas of altered signal intensity involving cortical gray and subcortical white matter in the bilateral frontoparietal regions,
occipital cortices, temporal cortices and cerebellar hemispheres, and hyperintensity on T2W and FLAIR sequences. Tapering
of prednisone and controlling hypertension resulted in clinical improvement within a few days, and in a month MRI was normal.
Diagnosing PRES requires a high index of suspicion when treating similarly susceptible patients. PRES as a complication during
the treatment of MPGN secondary to hepatitis B has, to our knowledge, never been reported previously in the literature. 相似文献

This work aimed at isolation and identification of patulin producing fungi and to follow the presence of patulin during apple juice processing. Among 34 Penicillium isolates, eight isolates (five from healthy appeared apples and 12 from rot spotted apples) were considered as patulin producers using thin-layer chromatography. These isolates were classically identified as a Penicillium expansum. PCR utilizing primers based on the polygalacturonase gene of P. expansum was applied for detecting this mold. The PCR amplified a 404-bp DNA product from all tested P. expansum isolates, but not in other common food spoilage Penicillium species. RAPD technique using P1 or M13 primers was applied to determine the similarity of the P. expansum isolates. RAPD results revealed that the tested strains showed high percentage of similarity and no correlation was observed between cluster analysis and the sources of isolation. Patulin could not be detected in healthy appeared apples and their extracted juice during different stages of juice process. In apple juice made from the healthy parts of apples decayed by P. expansum contained patulin which may present health hazard. The obtained results assured that patulin is known to be stable in apple juice even after pasteurization. In conclusion, the removal of the rotten part from the fruit is not sufficient to eliminate the mycotoxin patulin from apple juice. Although, the enzyme treatment (pectinase and amylase) and pasteurization (95 °C for 7 min) significantly (p < 0.05) reduced patulin level, its level is still higher than the level of <50 μg/kg considered by Codex alimentarius when the apple juice processed from the healthy parts of rot spotted fruits. 相似文献
