Shoulder adhesive capsulitis is a condition mainly characterized by a decreased range of motion (ROM), with a lifelong prevalence of 2-5 %. Intra-articular steroid injection is an important treatment in this disease. It has been suggested that ultrasound-guided (US-guided) intra-articular injections are more accurate and effective than blind injections. This randomized clinical trial was designed to compare efficacy and accuracy of US-guided injections versus blind injections of steroid in the glenohumeral joint. Forty-one patients diagnosed with shoulder adhesive capsulitis were included. Patients randomly underwent intra-articular injection either blind or under guidance of ultrasound by a specialist. Immediately after injection, radiograms were obtained to assess the accuracy of injection. Demographic characteristics, their functional status, the severity of pain, and the ROM were gathered and compared between the two groups. Twenty patients in the US-guided group and 21 in the blind group finished the 4-week period of the study. Improvements in pain, ROM, and functional score after 1 and 4 weeks were more prominent in the US-guided group, but the differences were not statistically significant, except for the changes in extension where the improvements were significantly higher in the US-guided group (p = 0.01). The accuracy of injections was also higher in the US-guided group (90 % vs. 76.19 %), but the differences were not found to be significant (p = 0.24). US-guided injections can be more accurate and yield better improvements in pain, ROM, and function of the patients, but they cost more and are time-consuming.

There is a remarkable gap between detection of existence and number of packets/baggies reported by the radiologists and the real condition of the patients. A close teamwork between radiologists and toxicologists is needed to manage these problematic cases.

Purpose: Pulmonary embolism (PE) is a potentially fatal cardiopulmonary disease; therefore, rapid risk stratification is necessary to make decisions of appropriate management strategies. The aim of this study was to assess various computed tomography (CT) findings in order to find new prognostic factors of adverse outcome and mortality. Material and methods: The study enrolled 104 patients with acute PE. Based on their outcome, patients were categorised into four groups. Comorbidities such as ischaemic heart disease were obtained from their medical records. Patients CT angiography were reviewed for recording variables such as main pulmonary artery diameter and right ventricle (RV)/left ventricle (LV) ratio. Patient deaths up to three months since diagnosis of PE had been registered. Logistic regression analysis was performed to find predictors. Results: Based on multiple logistic regression, RV/LV ratio, LV diameter, and right-sided pulmonary infarction are predictors of mortality in 30 days. An RV/LV ratio of 1.19 could successfully discriminate patients who died within 30 days and those who did not. Conclusions: RV/LV ratio, LV diameter, right-sided pulmonary infarction, assessed with helical CT, can help predict 30-day mortality.
