The role of routine coagulation studies in the management of patients suffering from epistaxis is unclear. In an attempt to address this issue the case notes of all emergency admissions for epistaxis to a large Scottish teaching hospital were retrospectively reviewed over a one-year period. One hundred and forty patients (63 male, 77 female) were admitted between January and December 1998. The patients who had coagulation studies were identified and their results analysed. A total of 121 patients (86.4 per cent) had coagulation studies performed. Of these, 10 (8.3 per cent) had abnormal results and all were taking warfarin or a combination of warfarin and aspirin. No other coagulation abnormalities were identified. This study supports the view that there does not appear to be a role for routine coagulation studies in patients admitted with epistaxis. The investigation for potential haemostatic disorders should be performed when clinically indicated and, if necessary, in consultation with the haematology service.
Ulnar subluxation of the extensor digitorum communis tendons at the metacarpophalangeal joints occurs rarely in the absence of rheumatoid disease or a history of trauma. Three elderly women presented with chronic ulnar subluxation of the extensor tendons of spontaneous onset. They did not have rheumatoid arthritis and had suffered no acute injury. Seven extensor tendon relocations were performed. The treatment options for this condition are discussed. Recognition of this condition is important if permanent loss of function and disability is to be avoided.
The establishment of diagnostic reference levels (DRLs) for all typical radiological examinations became mandatory following the implementation of the Ionising Radiations (Medical Exposure) Regulations Act 2000. At present, there are no national dosage guidelines in the UK regarding use of fluoroscopy in orthopaedic trauma. The increasing popularity of the mini C-arm image intensifier amongst surgeons has led to concerns regarding use of ionizing radiation by personnel who have not been trained in radiation protection. It is therefore essential to have formal protocols for use of the mini C-arm to comply with the law and to maintain safe clinical practice. It is attempted to provide dose data for wrist fracture manipulations that may be used as a basis for setting a DRL for this procedure. Screening times were recorded for 80 wrist manipulations in a fracture clinic setting using a mini C-arm image intensifier. A DRL was set using the third quartile value for screening time. The median screening time for wrist fractures was 20 s with a range from 1 to 177 s. The third quartile value for screening time was 34 s. This value can be used as a provisional DRL for wrist fracture manipulations. The DRL is a quantitative guide for the optimisation of radiological protection. IR(ME)R 2000 states that if it is consistently exceeded by an individual operator or a piece of equipment, investigation and remedial action must be taken. We recommend that trauma units establish their own local DRLs for common procedures as made mandatory by legislation.
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.
