Medial condyle Hoffa fractures are intra articular injuries, which require prompt anatomical reduction and internal fixation. Arthroscopy-guided fixation of these fractures has also been advocated; the advantages include avoidance of soft tissue dissection, fast recovery and mobilization. We describe a case of a 28-year-old male patient presenting with a 10-day-old medial condylar Hoffa fracture. Skin condition prevented from conventional open reduction and internal fixation; hence, taking note of the urgency of fixation of an intraarticular fracture, arthroscopic-assisted minimally invasive approach was performed with good outcome. 相似文献

Air samples were collected in 12 randomly selected commercial nail salons in Salt Lake County, Utah. Measurements of salon physical/chemical parameters (room volume, CO2 levels) were obtained. Volatile organic compound (VOC) concentrations were collected using summa air canisters and sorbent media tubes for an 8-h period. Multivariate analyses were used to identify relationships between salon physical/chemical characteristics and the VOCs found in the air samples. The ACGIH® additive mixing formula was also applied to determine if there were potential overexposures to the combined airborne concentrations of chemicals monitored. Methyl methacrylate was detected in 58% of the establishments despite having been banned for use in nail products by the state of Utah. Formaldehyde was found above the NIOSH REL® (0.016?ppm) in 58% of the establishments. Given the assortment of VOCs to which nail salon workers are potentially exposed, a combination of engineering as well as personal protective equipment is recommended. 相似文献

Acetabular fractures are relatively uncommon and their definitive treatment tends to be focused on specialist major trauma centres. This can make both accurate diagnosis and management challenging, particularly in hospitals where they are rarely seen. Contemporary management of these injuries owes a lot to the work of Judet and Letournel undertaken in the 1970s. The key to understanding these injuries is to know the embryology and development of the pelvis and then be able to appreciate its three-dimensional structure from two-dimensional X-rays. This can then be overlaid with the Judet classification and the action of force vectors encountered in various mechanisms of injury. It is also important to realise the ageing demographics of this group of patients and the complexities this adds to classification and ultimately treatment. Finally, the presence of an acetabular fracture is often seen in association with a number of other injuries. It is imperative that these are appropriately and contemporaneously diagnosed so that a comprehensive management plan may be instituted to give the best outcomes. However, even with optimal management the prognosis is guarded with a majority of patients suffering some degree of functional loss and this must be made clear to the patient from the outset. 相似文献

Sentinel lymph node biopsy (SLNB) is an accurate staging procedure for malignant melanoma but its use in patients with melanoma of the head and neck has been questioned in the past because of a perceived record of poor safety and accuracy. Technical improvements have sought to redress this. Vital structures and variable lymphatic pathways can make its use in the head and neck challenging. In our study we have examined the data and the experiences of clinicians from University Hospital Southampton and the Royal Surrey County Hospital. We retrospectively analysed the data and case notes of 143 patients who had SLNB to establish its safety, efficacy, and prognostic value. The detection rate of at least one sentinel lymph node was 100%. Nodes positive for metastatic melanoma were found in 20% of patients. Of them, 76% went on to have completion lymphadenectomy. Multivariate Cox regression analysis suggested that positive SLNB was a strong predictor of reduced overall survival for all Breslow-thickness melanomas (HR = 3.9, p = 0.019) and intermediate melanomas (HR = 6.3, p = 0.007). It predicted reduced recurrence-free survival for all melanomas (HR = 7.4, p < 0.001) and was a strong predictor for those of intermediate thickness (HR = 8.3, p < 0.001). The false negative rate was 9.4% and false omission rate 2.6%. Temporary and permanent morbidity rates were 2.1% and 0%, respectively. SLNB for melanoma in the head and neck is a safe, accurate staging procedure that offers prognostically useful information. The upstaging of disease allows access to trial-based targeted treatments. 相似文献

Simple bone cyst (SBC) also known as unicameral bone cyst is a benign, radiolucent bone lesion that is seen commonly in childhood. These lesions are usually found incidentally although pain and swelling can be seen. The most common complication is a pathological fracture, and this is often the cause of presentation. Here, we present a 22-year-old male with right lower quadrant pain due to SBC related pathological fracture of right iliac bone which is mimicking acute appendicitis. 相似文献
