Hip pain is a common problem seen by orthopaedic surgeons. The current authors provide an approach to the patient with hip pain, including important information to be gained from the history and physical examination and relevant radiographic studies and laboratory tests. A differential diagnosis for patients presenting with the complaint of hip pain and indications for hip arthroscopy are provided. 相似文献

Hip arthroscopy in the pediatric population 总被引:6,自引:0,他引:6
Hip arthroscopy has obvious advantages over arthrotomy in the pediatric population. Hip arthroscopy, used as a diagnostic or therapeutic tool, is significantly less invasive than arthrotomy and allows for quicker recovery and return to activities. In addition, arthroscopy avoids dislocation of the femoral head and the corresponding risk of osteonecrosis. Current indications for hip arthroscopy in pediatric patients include septic arthritis, labral disorders, slipped capital femoral epiphysis, and Legg-Calvé-Perthes disease. The role of hip arthroscopy in the pediatric population will continue to expand because of its attractiveness as a less invasive option for evaluating the hip. 相似文献

Attempts to design the macrocyclic maleimides as selective protein kinase C gamma inhibitors led to the unexpected discovery of a novel series of potent and highly selective glycogen synthase kinase-3beta (GSK-3beta) inhibitors. Palladium-catalyzed cross-coupling reactions were used to synthesize the key intermediates 17 and 22 that resulted in the synthesis of novel macrocycles. All three macrocyclic series (bisindolyl-, mixed 7-azaindoleindolyl-, and bis-7-azaindolylmaleimides) were found to have submicromolar inhibitory potency at GSK-3beta with various degrees of selectivity toward other protein kinases. To gain the inhibitory potency at GSK-3beta, the ring sizes of these macrocycles may play a major role. To achieve the selectivity at GSK-3beta, the additional nitrogen atoms in the indole rings may contribute to a significant degree. Overall, the bis-7-azaindolylmaleimides 28 and 29 exhibited little or no inhibitions to a panel of 50 protein kinases. Compound 29 almost behaved as a GSK-3beta specific inhibitor. Both 28 and 29 displayed good potency in GS cell-based assay. Molecular docking studies were conducted in an attempt to rationalize the GSK-3beta selectivity of azaindolylmaleimides. 相似文献

OBJECTIVE: We conducted a clinical trial to determine if prophylactic anticonvulsants in brain tumour patients (without prior seizures) reduced seizure frequency. We stopped accrual at 100 patients on the basis of the interim analysis. METHODS: One hundred newly diagnosed brain tumour patients received anticonvulsants (AC Group) or not (No AC Group) in this prospective randomized unblinded study. Sixty patients had metastatic, and 40 had primary brain tumours. Forty-six (46%) patients were randomized to the AC Group and 54 (54%) to the No AC Group. Median follow-up was 5.44 months (range 0.13-30.1 months). RESULTS: Seizures occurred in 26 (26%) patients, eleven in the AC Group and 15 in the No AC Group. Seizure-free survivals were not different; at three months 87% of the AC Group and 90% of the No AC Group were seizure-free (log rank test, p = 0.98). Seventy patients died (unrelated to seizures) and survival rates were equivalent in both groups (median survival = 6.8 months versus 5.6 months, respectively; log rank test, p = 0.50). We then terminated accrual at 100 patients because seizure and survival rates were much lower than expected; we would need > or = 900 patients to have a suitably powered study. CONCLUSIONS: These data should be used by individuals contemplating a clinical trial to determine if prophylactic anticonvulsants are effective in subsets of brain tumour patients (e.g. only anaplastic astrocytomas). When taken together with the results of a similar randomized trial, prophylactic anticonvulsants are unlikely to be effective or useful in brain tumour patients who have not had a seizure. 相似文献
