Establishment of national diagnostic reference levels in dental cone beam computed tomography in Switzerland.

CONCLUSIONS: Large ranges of FOV and PKA were found for a given indication, demonstrating the importance of establishing DRLs as well as FOV recommendations in view of optimizing the present practice. For now, only DRLs for dental and maxillofacial could be defined; because of a lack of ENT data, no DRL values for ENT practices could be derived from this survey.

The objective of this study was to provide an overview of whether adherence to brain trauma foundation (BTF) guidelines improved outcomes following TBI utilizing intracranial pressure (ICP) monitoring. Methods: This cohort study between 2000 and 2013 involved 1848 patients who sustained severe blunt TBI. Outcomes were correlated with whether or not ICP monitoring was utilized based on BTF guidelines. Results: The BTF guideline adherence rate for utilizing ICP monitoring in patients with TBI was 30% in 1848 patients. Adherence rates positively correlated with younger age, high injury severity scores, lower Glasgow C...

Conclusion: Direct compression of ICA is rare complication of pituitary apoplexy, which caused cerebral ischemia. Conventional angiography should be necessary for accurate diagnosis and prompt surgical decompression should be the treatment of choice. PMID: 32494388 [PubMed]

Conclusions: Excellent accuracy was found for types 1A, 1B, and 3C deformities (ends of spectrum). There was more variation among surgeons in differentiating between one-column (types 2A and 2B) and two-column (types 3A and 3B) deficiencies, as surgeons often failed to recognize the radiological signs of posterior column failure. This failure to identify column deficiencies can potentially alter kyphosis management. There was excellent consensus among surgeons in the recommendation of type 2 osteotomy; however, some variation was observed in their choice for other osteotomies.

Authors: Bund L, Tricard T, Alexis W, Schneider L, Karger C, Gicquel P Abstract Closed reduction and percutaneous osteosynthesis is an alternative to the open procedure for articular fractures of distal tibia of children. 38 patients were retrospectively reviewed. The measured parameters were : the score of Gleizes and the discrepancies between preoperative radiographic and CT scan measurements and postoperative radiographs. A significant correlation was found between the gap and the step-off in preoperative radiographic and CT scan. A significant decrease of the gap and step-off displacement was noticed after surg...

Authors: Behaeghe O, Van Beeck A, Dossche L, Somville J Abstract The aim of this study was to evaluate the inter- and intraobserver reliability of a CT-based femoral anteversion measurement. 17 CT scans showing an abnormal anteversion on one side were presented to 6. Three measurements of all scans were obtained : two bilateral measurements and a third measurement with a flipped CT scan. Interobserver correlation results using the spearman test for left, right and anteversion difference had a mean of respectively : 0.918, 0.760 and 0.757. Intraobserver correlation had a maximum of respectively : 0,99, 0,89 and 0,94...

One of the more insidious features of the new coronavirus behind COVID-19 is its ability to settle into unsuspecting hosts who never show signs of being sick but are able to spread the virus to others. In a study published June 3 in the Annals of Internal Medicine, researchers at the Scripps Research Translational Institute reviewed data from 16 different groups of COVID-19 patients from around the world to get a better idea of how many cases of coronavirus can likely be traced to people who spread the virus without ever knowing they were infected. Their conclusion: at minimum, 30%, and more likely 40% to 45%. Such so-ca...

Authors: Nasor M, Obaid W Abstract Brain tumors are a major health problem that affect the lives of many people. These tumors are classified as benign or cancerous. The latter can be fatal if not properly diagnosed and treated. Therefore, the diagnosis of brain tumors at the early stages of their development can significantly improve the chances of patient's full recovery after treatment. In addition to laboratory analyses, clinicians and surgeons extract information from medical images, recorded by various systems such as magnetic resonance imaging (MRI), X-ray, and computed tomography (CT). The extracted informat...

We report the case of an 82-year-old male diagnosed with a metastatic castration resistant prostate carcinoma, under chemotherapy with disease progression in treatment with high doses of intravenous morphics. The patient reported abdominal distension with constipation and no vomiting in the emergency department and a distended and tympanic abdomen, without generalized peritonitis was identified during physical examination. A blood analysis showed lactate levels of 0.9 mmol/L and a PCR of 4.2 mg/L without leukocytosis. An extensive colonic pneumatosis with minimum pneumoperitoneum without free fluid was confirmed by a compu...
