Sonoelastography can be considered as a reliable screening tool for characterizing thyroid nodules. An elasticity score of 1 is indicative of benign pathology in almost all cases and can be used to exclude many patients from further invasive assessments.
Early diagnosis and treatment of hepatocellular carcinoma are important because only 10% of patients meet the criteria for curative therapy at the time of diagnosis. Several organizations have developed guidelines for screening, diagnosis, and treatment of hepatocellular carcinoma. Radiologists play a pivotal role in every aspect of these guidelines.
An allergiclike reaction to both nonionic ICM and GBCM was an extremely rare event that presented as a mild acute reaction without significant clinical consequences despite the fact that an allergy preparation was not administered.
To assess the effectiveness of cyclophosphamide in the management of scleroderma-related interstitial lung disease (ILD). In this systematic review study, the primary outcome measures were change in forced vital capacity (FVC) and diffusing capacity of the lung for carbon monoxide (D(L)CO) of the patients after 6 and 12 months. To assess the effect of cyclophosphamide on early stage of ILD, alveolitis, in SSc patients, we selected the studies that used the BAL findings or HRCT or recent deterioration of PFT with minimal chest X-ray finding in early stage of disease as diagnosis of alveolitis. A sensitive systematic search strategy was used to find all relevant studies. Finally, 17 trials were included in the analysis that was performed using STATA. (Version 8) and Review Manager (version 4.1; MetaView version 4.1) softwares. Results from 10 studies were pooled for the outcome variable of FVC after 12 months. The summary WMD (random effects) was 2.45 (95% CI, 0.760-4.149 P = 0.005), which means that cyclophosphamide was able to prevent deterioration of FVC after 12 months. In pooled data of 13 studies, about DLCO after 12 months WMD (random effects) was 2.003 2.96 (95% CI, -0.228 to 6.159 P = 0.069), which means that cyclophosphamide was not able to prevent deterioration of D(L)CO after 12 months. If we considered clinically sensible improvement as absolute value ≥10% in DLCO and VC, then result of treatment with cyclophosphamide treatment in scleroderma patients with ILD was not significant.
The threshold of 17.1 HU may be the appropriate cutoff for nonenhancement in a necrotic HCC. Use of this threshold may potentially affect how response to therapy is quantified and categorized.
Gunshot injuries of the brachial plexus are a challenging issue among peripheral nerve lesions. Surgical reconstruction of such injuries is difficult and the clinical outcome depends on several factors. The aim of this study was to present the outcome of surgical management of gunshot injuries of the brachial plexus that occurred following Iran-Iraq war. Twenty patients with 55 injured elements of the brachial plexus underwent surgery in Loghman-Hakim Hospital during 1982 and 1992. Reconstructive procedures included neurolysis in 30 injured elements, nerve grafting in 17 and a combination of these two methods in 8 cases. Surgical procedure was selected based on the microscopic findings during the operation. Final recovery outcome was assessed at least 3 years after surgery on the basis of motor and sensory recoveries. Final outcome was defined as poor, intermediate, and good. Both good and intermediate outcomes were considered as useful recovery. An acceptable recovery was obtained in 28 of 30 (94%) injured elements undergone neurolysis, 15 of 17 (89%) elements in nerve graft group, and 7 of 8 (87.5%) elements reconstructed with neurolysis in combination with nerve graft. In neurolysis, good recovery was more frequent and obtained in 23 of 30 (77.5%) lesions. Best treatment outcome was observed in lesions of lateral cord to musculocutaneous nerve which all injured elements showed good recovery. Impairment in none of the lesions in the level of posterior cord and lower trunk or C8-T1 led to good recovery. In surgical reconstruction of gunshot injuries of the brachial plexus the most favorable results were observed in the neurolysis reconstruction of the lesions in the lateral cord to musculocutaneous nerve. In the absence of spontaneous improvement of neurologic deficit, surgical procedures should be done as soon as possible according to the type and location of injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
