BACKGROUND: This study evaluated the usefulness of the serologic test for syphilis (STS) in preventing the transmission of human immunodeficiency virus (HIV), hepatitis B and C viruses, and human T- lymphotropic virus via the transfusion of seronegative, infectious window-period blood. STUDY DESIGN AND METHODS: Demographic and laboratory information on blood donations made between January 1992 and June 1994 in 18 American Red Cross regions was analyzed. It was assumed that the same proportion of HIV-positive and HIV-infectious window- period donations reacted on STS and were negative on other screening tests (hepatitis B and C viruses and human T-lymphotropic virus). This proportion multiplied by the estimated number of HIV-infectious window- period donations is the number of post-screening HIV-infectious donations removed by STS. RESULTS: Of 4,468,570 donations, 12,145 (0.27%) were STS positive and 377 (0.008%) were HIV positive. Among donations that were negative on other screening tests, STS-reactive donations were 12 times more likely to be HIV positive (odds ratio = 11.9; 95% CI = 5,26). However, of an estimated 13 infectious window- period donations, 0.2 would have been removed because of a reactive STS, at a cost of over $16 million. CONCLUSION: STS is a poor marker and a costly strategy for preventing post-screening HIV infections and other blood-borne diseases. 相似文献

Objective Recently, a novel renal carcinoma with specific clinical and histological characteristics and translocation t(6;11)(p21.1;q12
or q13) has been identified. We have found 11 cases in the literature, and we are adding another 3 cases.
Materials and methods Three cases were found in the Plzeň pathological register with approximately 15,000 cases of kidney tumors. There were two
females and 1 male, aged 22, 24, and 39 years.
Results The sizes of the tumors were 40, 136, and 10 mm. Two tumors were found incidentally; the biggest one was self-palpated by
a 24-year-old pregnant patient. Patients are without any signs of disease 42, 20, and 17 months after surgery.
Conclusion This tumor is a distinctive and rare translocation carcinoma of the kidney [t(6;11), HMB45 positive]. All cases with known
clinical data arose in younger people. The malignant potential is probably low.

Background
Adenoidectomy is a commonly performed ENT surgery. It is conventionally performed using the curettage method. This present article aims to evaluate endoscopic powered adenoidectomy as an alternative.Methods
Sixty consecutive cases requiring adenoidectomy were randomized into two groups of thirty each. Group A underwent conventional adenoidectomy using the curettage method and Group B underwent endoscopic assisted micro-debrider adenoidectomy. The parameters studied were intra-operative time, intra-operative bleeding and completeness of resection, collateral damage, post operative pain and recovery time.Result
Sixty cases of adenoidectomy were done using conventional surgery and powered endoscopic adenoidectomy in the study period from Aug 04 to Dec 05. The time taken in Group A (conventional surgery) varied from 22–39 minutes (95% Confidence Interval (CI) −27.7 – 30.9)and in Group B (powered endoscopic surgery) from 27–55 minutes(95% CI 36.6 – 41.9) (p<0.05). The average blood loss in Group A was 21 ml (range 10–50) as compared to 31.67 ml (range 10-60) in Group B (p<0.05). The resection was invariably complete in Group B whereas seven(23%) cases had more than 50% residual adenoid tissue in Group A. Three cases in group A had collateral damage whereas in Group B, there were no added injuries. Post operative pain was studied only in cases undergoing adenoidectomy alone. Group A (n=8) demonstrated a pain score of 1.64–2.63–3.63 (95% CI) whereas Group B (n=11) demonstrated a pain score of 1.19–2.13–3.06 (95% CI). This difference was not statistically significant. In group A, the mean recovery period was 3.5 days and 2.93 days in Group B(p<0.05).Conclusion
Endoscopic powered adenoidectomy was found to be a safe and effective tool for adenoidectomy. The study parameters where endoscopic powered adenoidectomy fared better were completeness of resection, accurate resection under vision, lesser collateral damage and faster recovery time. On the other hand, conventional adenoidectomy scored in matter of lesser operative time and intra-operative bleeding.Key Words: Adenoidectomy, Powered adenoidectomy, Endoscopic adenoidectomy 相似文献39.

Endotoxin-removal direct hemoperfusion column containing polymyxin B immobilized fibers (PMX-DHP) is an effective procedure for the treatment of sepsis-induced acute respiratory distress syndrome (ARDS). We investigated retrospectively the effects and appropriate timing of PMX-DHP induction for directly induced ARDS in 38 patients. PMX-DHP was carried out twice for two hours. Blood pressure, heart rate (HR) and PaO(2)/FIO(2) (PF) ratio, leukocytes, platelets, endotoxin, inflammatory cytokines and clusters of differentiated peripheral neutrophils and monocytes were measured before and after PMX-DHP. Acute Physiology and Chronic Health Evaluation (APACHE) II scores, Sequential Organ Failure Assessment (SOFA) scores and lung injury scores (LIS) were determined at the time of starting PMX-DHP. The underlying causes of ARDS were pneumonia in 29 patients and aspiration pneumonia in 9 patients. The patients were divided into Survivors (n = 21) and Nonsurvivors (n = 17). Mortality was 45% at 30 days after PMX-DHP. The APACHE II and SOFA scores and the LIS were not significantly different between the two groups. The time from the onset of ARDS to the start of PMX-DHP was significantly delayed between the two groups. PMX-DHP significantly improved the PF ratio, HR and systolic blood pressure in the Survivors compared to the Nonsurvivors. The function of active monocytes in the peripheral blood was significantly suppressed after PMX-DHP. This early induction of PMX-DHP is indicated for directly induced ARDS. In the Nonsurvivors, this delay could have led to undesirable responses to oxygenation and circulation after PMX-DHP. 相似文献
