The purpose of this study was to assess the effect of psychiatric illness on length of stay and patterns of admission among AIDS patients hospitalized for medical illnesses. Medical records were abstracted for AIDS patients admitted to hospitals in Washington State from 1990 through 1992. Psychiatric comorbidity was defined by the presence of an International Classification of Disease-9 code reflecting psychiatric illness. Medical morbidity was addressed using CD4 count and AIDS-defining illnesses as markers of disease severity. Of 2834 admissions, 15% included one or more psychiatric diagnoses. Psychiatric illness (F 39.1; df 1,2830; p < 0.001) and discharge disposition (F 81.2; df 2,2830; p < 0.001) contributed significantly to the model, explaining increased length of stay (F 67.2; df 3,2830; p < 0.001). Future research needs to address the possible etiology of psychiatric comorbidity's contribution to length of stay and the effect on quality and cost of care. 相似文献

The results following internal fixation of displaced subcapital femoral fractures are poorer than for undisplaced fractures and are determined by both the quality of the initial reduction and the accuracy of implant placement. In a series of 26 consecutive displaced fractures internally fixed with Richards hip pins, satisfactory reduction was achieved in only 15 hips. Accurate reduction is a prerequisite for correct screw placement and occurred in only 4 of the 11 poorly aligned fractures, as opposed to 11 of the 15 well reduced ones. A total of 10 hips required a further surgical procedure as the result of complications. These results highlight the importance of accurate fracture reduction in facilitating implant placement as well as the importance of good surgical technique rather than reliance purely upon the implant. These already common fractures are assuming increasing socioeconomic importance as the elderly population grows, and successful management is vital for both the individual patient and future demands on the health service. 相似文献

Weakening of the Z-disks of skeletal muscle myofibrils contributes to the tenderization of meat during post-mortem aging. To elucidate the weakening mechanism, we compared Z-disks weakened by post-mortem aging of chicken breast muscle with those of myofibrils treated with a solution containing 0.1 mM CaCl2 and 1 microM calpastatin domain I. In both cases, the Z-disks were weakened with a corresponding liberation of their constituent phospholipids (PLs). The liberation of PLs specific to 0.1 mM calcium ions was minimal at pH 6.5 and maximal at 35 degrees C together with the Z-disk weakening. Binding of calcium ions to PLs in the Z-disks was determined by 45Ca-autoradiography. Acidic PLs were strongly radioactive and neutral PLs were appreciably radioactive. It is very probable that acidic PLs would bind electrostatically to alpha-actinin under physiological conditions, and that this interaction would be broken by the binding of calcium ions at 0.1 mM to PLs, resulting in the partial liberation of PLs from Z-disks. We conclude, therefore, that the liberation of PLs by the binding of 0.1 mM calcium ions was the main cause for Z-disk weakening during the post-mortem aging of chicken. 相似文献

Videolaparoscopic cholecystectomy is considered the treatment of choice for simple cholelithiasis. Now many surgeons consider the laparscopic procedure usable also in the complicated biliary lithiasis like acute cholecystitis and choledocholithiasis. The authors report their recent experience of the laparoscopic treatment of biliary lithiasis, regarding 221 non-selected patients (69% symptomatic cholelithiasis, 20% chronic cholecystitis, 4.5% acute cholecystitis, 4.5% coledocolithiasis, 2% hydrops). The diagnostic-therapeutic protocol and the results are described and compared with the beginning of their experience, when they treated only symptomatic gallbladder stone disease, and with the reports of the literature. The authors concluded that the laparoscopic procedure is a good chance for the surgeon in the treatment of all cases of benign biliary disease. But, in particular for patients with choledocholithiasis, he has be able to know all the diagnostic and therapeutic possibilities, to choose the best in every single case. 相似文献

The authors present a case of tremor isolated to the lower extremity that was treated with stereotactically guided thalamotomy in a patient with Parkinson's disease. The technology that makes this procedure effective for this particular manifestation of parkinsonism is discussed. 相似文献

There is a dramatic resurgence of human African trypanosomiasis (HAT) in sub-Saharan Africa. T.b. gambiense is spreading epidemically in large areas of Central Africa, especially the Southern Sudan, Congo-Zaire, Angola, Uganda and the Central African Republic. Devastating epidemics of T.b. rhodesiense have occurred in south-eastern Uganda. The causes of the re-emergence of sleeping sickness as a public health problem include widespread civil disturbance and war, declining economies, reduced health financing and the dismantling of disease control programmes. Despite the inevitably fatal outcome without treatment, HAT is often given low priority by donors and national governments. The advances made in diagnosis, treatment and vector control have not been sufficiently implemented. To limit the human impact in some of the poorest communities in Africa, endemic countries will require external support to implement strategies for disease control. Donor agencies, NGOs and mission organisations could play an important role in supporting control efforts. National authorities will need to control and co-ordinate these efforts with assistance from WHO and the international community. 相似文献
