Background Morbidity and mortality of advanced human immunodeficiency virus infection （HIV） have declined in Western industrialized countries since the availability of highly active antiretroviral therapy （HAART）. It is unclear if this has also happened in Hong Kong. Methods We studied a retrospective cohort of patients with advanced HIV disease in Hong Kong, China. First, the mortality of advanced HIV disease per year was calculated for the decade 1993 to 2002, both annually and according to patient observation before and after 1997. Second, the event rates were estimated for the clinical end points of acquired immune deficiency syndrome （AIDS） and death. Univariate and multivariate analyses were then performed to identify associated factors. Results The crude mortality of advanced HIV disease declined from 10. 8 - 30. 4 per 100 patients during 1993 - 1996, to 0. 8 - 6. 9 per 100 patients during 1997 - 2002. A rate ratio of 4. 04 （95% CI, 2. 52 - 6. 47） was evident for those observed in 1993 - 1996, compared to those in 1997 - 2002. In a multivariate analysis where calendar period was adjusted, use of＇highly active antiretroviral therapy was associated with rate ratios of 0. 13 （95% CI, 0. 05 -0. 33） for death after AIDS, 0. 08 （95% CI, 0. 04 -0. 19） for AIDS after a CD4 cell count 〈200/μ1, and 0.21 （95% CI, 0.07 -0.67） for death after CD4 cell count 〈200/μl. In the same analysis, calendar period ceased to be a significant factor after adjustment for use of HAART. Conclusions The mortality and morbidity of advanced human immunodeficiency virus disease have declined in Hong Kong. This improved prognosis was attributable to the use of highly active antiretroviral therapy.

The First Cases of laparoscopic Colectomy for Cancer in Ziguinchor Peace Hospital

引用

Surgical Science 2023年第8期14卷 550-556页

laparoscopic colectomy is a standardized technique for the curative treatment of colon cancer, based on the principles of carcinological surgery. It is rarely performed in our region but common practice in developed countries. We conducted a retrospective study of the first 4 cases of laparoscopic colectomy for cancer. The patients were 3 men and 1 woman, with a mean age of 54.2 years. Of the 4 cancers, 3 were localized to the sigmoid and one to the cecum. The main symptom was rectal bleeding. Total colonoscopy with biopsy was performed in 3 patients and the histological type was a lieberkühnian, infiltrative, moderately differentiated adenocarcinoma. Thoraco-abdomino-pelvic computed tomography (TAP CT) was performed in all the cases. Three patients were presented to the multidisciplinary team (MDT) prior to surgery. The operations were one right hemicolectomy and three left hemicolectomies. The mean operative time was 182.25 min [152 - 210]. Average blood loss was estimated at 200 cc. The average hospital stay was 4.71 days. Cancer staging was classified as stage I in 1 case (p T1N0M0) and stage III in 3 cases (pT3N1Mx, pT3N2Mx). Resection margins were healthy. The number of lymph nodes removed was 12, 14, 17 and 13 respectively. Conclusion: This is a safe and reproducible technique, but requires a much higher cost than laparotomy.

用全氮、有机质、pH、碳氮比及质地不同的12种土壤进行了大麦、燕麦和黑麦等3种作物的盆栽试验,并以KCl煮沸法测定了其可矿化的氮素,以估计土壤潜在的有效氮素。试验表明,KCl浓度及浸取时间长短对NO_3^--N浸出量无明显影响,用1 mol/l KCl煮沸浸取1h之后,NH_4^--N亦增加不多。1 mol/l KCl煮沸1h所释放的氮素与3种作物吸氮量密切相关,证明了这种水解方法能较好地预报盆栽试验条件下不同土壤释放作物可利用氮素的相对能力。一旦包括土壤特性,温、湿度在内的氮素释放模式形成之后,KCl煮沸法有可能用来很好地预报大田条件下作物生长期间转变成有效态氮素的数量。
