Pain management must involve treating the cause of the painwhere possible, for example appropriate use of antibiotics forinfection, fixation for fractures, spinal stabilization. Wherethe cause of pain cannot be removed entirely, treatment shouldbe directed at modifying the disease process if possible, forexample palliative radiotherapy and/or chemotherapy, bisphosphonatesfor hypercalcaemia, surgery for bowel obstruction. Attentionto a patient's physical environment is important and simplemeasures, for example use of appropriate mattresses, orthotics,and mobility or bathing aids, . . . [Full Text of this Article]

Three cases of enteritis necroticans seen at Port Moresby General Hospital are described. All three cases proved diagnostic problems and in all three the diagnosis was made only at laparotomy. While the condition is uncommon in Port Moresby, these cases indicate that it must now be considered earlier rather than later.  相似文献

Using Syva EMIT reagents and a Cobas Bio centrifugal analyser we have developed a cost-effective assay for the detection of cannabinoids in urine. With this method, up to 1500 samples can be assayed with a single 100 test kit while maintaining acceptable precision. A mean CV of 6.1% was obtained for the concentration range 80-130 micrograms/l. The method is suitable for high-risk urines since heart treatment may be performed prior to analysis. There was no significant change in the measured concentration of cannabinoids in urine samples on storage in plastic containers, refrigerated or frozen, for up to seven weeks.  相似文献

The absolute activities of the pure beta-emitters 89Sr and 90Y have been determined by a direct method, namely the triple-to-double coincidence ratio (TDCR) efficiency calculation technique. This undertaking has extended further the number of radionuclides that have been standardized by this non-extrapolation liquid scintillation (LS) method. Both measurements were carried out within the framework of international key comparisons under the auspices of the International Bureau of Weights and Measures (BIPM). The TDCR results agreed well with those of other participating national laboratories, most using alternative (tracer) methods.  相似文献

Curative local excision of rectal adenocarcinoma   总被引:3,自引:0,他引:3  
The records of all 28 patients with rectal adenocarcinoma treated by potentially curative local excision by one surgeon (A.M.C.) between 1970 and 1984 were reviewed. Patient age, sex, tumour size, site, degree of differentiation and level of invasion are reported. The procedure was associated with no mortality and minimal morbidity. Twenty-two patients, followed for an average of 51 months, have either died of other causes or remain free of recurrent or disseminated malignancy. Six patients have required further surgery for local recurrence. Of these, one patient has had a repeat local excision while the remaining five patients have had an abdominoperineal excision of the rectum. All six patients, followed since the second operation for an average of 50 months, are free of further recurrent or disseminated disease. The results reported in this review suggest that in a selected group of patients with rectal adenocarcinoma curative local excision may offer a safe alternative to more radical forms of surgery.  相似文献

Background  

Previous studies regarding the use of information technologies (IT) specifically among pediatricians and other physicians who treat children are lacking. As such, the objective of this study is to examine the use of electronic health record (EHR) systems and other IT applications among pediatricians and other child health providers (CHPs) in Florida.  相似文献

The first 150 words of the full text of this article appear below. Key points Cancer pain management services must integrate withpalliative and primary care. Pain is common in cancer and usuallyoccurs in more than one site. Careful assessment and treatmentsaimed at the causes of the pain are essential. Optimal oralpharmacotherapy manages more than 75% of patients with cancerpain. If specific anti-cancer therapy, drugs, physical andpsychological treatments fail, then more invasive therapiesshould be considered early.
