A questionnaire was developed to evaluate internists' perceptions about patients' survival of cancer as compared with other diseases. The questionnaire consisted of four pairs of survival-matched cancer and non-cancer diseases. The questionnaire was administered to 42 faculty members and 37 resident physicians in the Department of Medicine at the University of Missouri-Columbia. Physicians rated patients' survival of cancer to be significantly lower than patients' survival of comparable non-cancer diseases (p less than 0.001). Resident physicians estimated patients' survival of breast cancer to be significantly lower (p less than 0.007) and estimated the survival of lung cancer to be significantly higher than the faculty members' estimate (p less than 0.003). These physicians' perceptions could adversely affect the quality of care and the degree of consideration given to both cancer and non-cancer patients. The differences observed in faculty members' and resident physicians' responses were attributed to the greater knowledge and clinical experience of faculty rather than differences in attitudes toward cancer. 相似文献

Anti-Sc1 was detected in a gravida-2 patient at 12 weeks' gestation. At 29 weeks, the antibody was found to be of the IgG3 subclass with a titer of 16, score 36, by the indirect antiglobulin test, and it produced 7 percent lysis by antibody-dependent cellular cytotoxicity (ADCC) assay, a finding that suggested an unaffected fetus. The titer remained constant throughout the pregnancy, as did the IgG subclass and activity in the ADCC assay. At delivery of the full-term infant, the cord hemoglobin was 13.5 g per dL and the direct antiglobulin test was positive (3+) with anti-IgG. The infant did not require transfusion. A sample taken 9 weeks after delivery showed 44 percent lysis in the ADCC assay. The anti-Sc1 titer was 32, score 65. 相似文献

Chronic sun exposure leads to photodamage, which is characterized clinically by fine and coarse wrinkles, dyspigmentation, telangiectasia, laxity, roughness and a sallow appearance. Many treatments claim to reduce the signs of photodamage, however evidence from randomized controlled trials (RCT) to support these claims is limited. The use of topical retinoids, particularly tretinoin, isotretinoin and tazarotene, has been shown to significantly reduce signs of photodamage both clinically and histologically. Over recent years a number of RCTs, have affirmed that topical tazarotene is an effective and safe treatment for photodamaged skin. 相似文献

BACKGROUND: Recent improvements in video technology and surgical instrumentation have resulted in the application of minimally invasive techniques to many surgical procedures including splenectomy and adrenalectomy. Nephrectomy requires a long flank incision with division of abdominal musculature and possible subcostal nerve damage. Severe postoperative pain and a prolonged recuperative period may result, and the cosmetic outcome may not be satisfactory. A new surgical approach utilizing laparoscopic dissection and delivery of the kidney through a small incision was performed to circumvent these problems. The aim of this paper is to describe the technique of laparoscopic live donor nephrectomy (LLDN) and present the preliminary outcome. METHODS: Over the 12-month period between May 1997 and April 1998, 16 donors underwent donor nephrectomy by a laparoscopic approach. The procedure was assessed with regard to its safety, feasibility and advantages over the open method. RESULTS: All the nephrectomies were completed without conversion to an open procedure. The average postoperative pain score on a visual analogue scale of 1-10 was 2 in LLDN. The donors required 36 mg morphine on average over 36 h postoperatively. Postoperative stay averaged 3 days. One donor developed an infective complication along the wound drain tract which settled with adequate drainage and antibiotics. All the removed donor kidneys were transplanted with immediate good function. There were no surgical complications or graft losses. The recipients' serum creatinine was in the range of 96-181 mmol/L 3 months after transplantation. CONCLUSIONS: Significant potential advantages of LLDN include less postoperative pain, shorter hospitalization and decreased recuperative time. This preliminary experience indicates LLDN to be effective in terms of safety and feasibility. 相似文献

A study was undertaken to determine the degree of acute bone marrow and vital organs injury sustained when dogs were administered doses of 153Sm-EDTMP calculated to irradiate an acute bone lesion arising from cancer metastasis to a dose considered palliative or even therapeutic (20-160 Gy). The study revealed significant (p less than 0.05) temporary depression of the bone marrow in all doses in the therapeutic (greater than 40 Gy) range. Palliative (20 Gy) doses caused significant leukocyte depression but insignificant (p greater than 0.05) depression of platelet and packed cell volumes when compared to control animals. A mild transient rise in the levels of serum alkaline phosphatase occurred immediately following radioisotope administration. All hematologic parameters had returned to normal by six weeks after the last injection of radioisotope. The study indicates potential for this compound as a safe, therapeutic radiopharmaceutical for treatment of cancer bone metastasis. 相似文献

SUMMARY Four cases of primary meningococcal conjunctivitis in children are reported. This represents an incidence of 2% of patients presenting with conjunctivitis to a paediatric A&E department. All were initially treated with topical chloramphenicol, followed by systemic rifampicin once the diagnosis had been established. No ocular or systemic complications developed, nor recolonisation of the conjunctiva or colonisation of the nasopharynx at follow-up (1–2 years). 相似文献

Summary A new conventional simple and direct125I-radioimmunoassay (RIA) for serum progesterone is described. In comparison with the classical tritiated assays which are
preceded by extraction, the assay is more simple, less time-consuming, less subject to error and hence less expensive. In
normal cycling females the serum progesterone range during the follicular phase was 0.9 to 5.5 ng/ml (mean 2.5 ng/ml). Levels
above 12 ng/ml occurring during the luteal phase are indicative of adequate luteal function. The actual progesterone levels
assayed with this method are significantly greater than those found using the classical tritiated technique, and the reasons
for this discrep. ancy are discussed. The assay is also capable of being used to assess the response to treatment for infertility,
thus indicating that, in spite of the higher values obtained, there is no impairment in diagnostic sensitivity. 相似文献
