Glafenine-associated anaphylaxis as a cause of hospital admission in the Netherlands

Summary In 1981 generalized anaphylaxis was registered on 166 occasions in Dutch general and academic hospitals. Clinical details of 120 of those patients revealed that in 107 anaphylaxis was either probable (n=90) or possible (n=17), whereas in 13 cases some other reaction than anaphylaxis had occurred. The series of confirmed cases contained 46 men and 61 women, with mean ages of 47 y and 48 y, respectively.There was a complete recovery in 102 patients and two patients died. Hypotension was present in 79 cases (74%), dyspnoea in 34 cases (32%) and a skin reaction, mainly urticaria, erythema or angioedema, was mentioned in 62 cases (58%). Most cases of anaphylaxis were drug-induced (76%), the main causes being the analgesic glafenine and contrast media. Glafenine was mentioned as the cause in 36% of all admissions for drug-induced anaphylaxis. Only 3.7% of cases had been reported to the voluntary reporting scheme of the Netherlands Centre for Monitoring of Adverse Reactions to Drugs.On the basis of reimbursement data, the risk of developing severe anaphylaxis to glafenine was estimated at 11.7–19.3-fold relative to indomethacin, and 13.4–20.2-fold relative to oral penicillins.     

Natural killer cell activity and autologous mixed lymphocyte response of splenic,mesenteric lymph node,and colonic lymphocytes during DMH-induced colon carcinogenesis in the rat

Twoin vitro models of immune surveillance were used to examine the immune status of the gut-associated lymphoid tissue, mesenteric lymph nodes, and spleen during the early stages of 1,2-dimethylhydrazine (DMN)-induced colon tumorigenesis. DMH-and vehicletreated Fischer rats were sacrificed at one of three time points; one week, two months, or five months after cessation of treatment. Colonic, lymph node, and splenic natural killer cell cytolytic activity toward YAC-1 tumor targets and T-cell response to autologous la-induced balstogenesis were measured at each time point. We found little change in natural killer cell activity or T-cell proliferation induced by autologous Ia gene products at these time periods.This investigation was supported in part by grant CA26917 from the National Cancer Institute, Department of Health and Human Services.

岳阳市1993～2002年性病流行病学分析

目的 了解岳阳市10年来性病的发病趋势和流行特点，为政府部门制定性病防治策略提供科学依据。方法 用性病疫情软件汇总分析全市性病疫情报告的年度报表。结果 岳阳市10年共报告8种性病6492例，其中：淋病2851例，非淋菌性病尿道炎888例，尖锐湿疣2425例，梅毒192例，生殖器疱疹117例，软下疳7例，性病性淋巴肉芽肿3例，HIV感染9例。年平均发病率为12．71／10万，年平均增长率为1，34％。同时，数据显示传染来源中非婚性接触4909例，占总例数的75，62％，性乱人群是性病传播的主要方式。结论 岳阳市性病仍属于低发地区，目前正处于逐步扩散期。尖锐湿疣、梅毒上升幅度较大，应加强防治力度，控制疾病的流行。     

温州市外来流动人口传染病的监测

目的：为了解温州市流动人口传染病的发病情况，加强这些人群的传染病防制和监测工作。方法：我们对温州市1997－2000年甲，乙类传染病报告资料进行调查，整理和分析。结果：（1）流动人口传染病年均报告发病率为44．75／10万；（2）省外流动人口传染病报告发病率（55．55／10万）高于省内（12．03／10万）；（3）流动人口传染病发病率以呼吸道，肠道，血源和性传播疾病为高，而虫媒与自然疫源性疾病和新生儿破伤风相对较低；（4）流动人口中肺结核，乙肝，甲肝和痢疾的发病率较高，其发病数均占总病数的10％以上；（5）流动人口疟疾和新生儿破伤风发病率高于当地人群，而其它传染病发病率则低于当地人群。结论：目前，流动人口传染病问题已日益突出，对社会稳定和经济发展将发生严重影响，采取合适的防制措施对控制流动人口传染病是非常迫切和必要的。     

流行性出血热若干体液因子和肾脏血液动力学的变化

对28例流行性出血热（EHF）患者作了体液因子和肾脏血液动力学的观察研究。发现患者从发热期至多尿初期血浆内皮素（ET）、血栓素B2（TXB2）、血管紧张素-Ⅱ（AT－Ⅱ）均高于正常，P物质（SP）则低于正常，6-酮前列腺素F1α（6-k-PGF1α）除极期外其它各期亦见减低，肾小球滤过率（GFR）与肾有效血浆流量（ERPF）从发热后期至多尿期均显著下降，至恢复初期多数重型患者仍未达到正常。上述结果提示体液因子的失衡是造成内脏缺血和急性肾衰的重要因素。     

Lumbar Puncture Ordering and Results in the Pediatric Population: A Promising Data Source for Surveillance Systems

Background: The Centers for Disease Control and Prevention is incorporating laboratory data into real-time surveillance systems. When normal patterns of laboratory test orders and results are modeled, aberrations can be detected. Because many test orders are available electronically well before results, atypical patterns of test ordering may signal outbreaks.
Objectives: The authors sought to characterize baseline patterns in the ordering and early results of lumbar punctures, motivated by the possibility of using these data for real-time surveillance for early detection of meningitis or encephalitis outbreaks.
Methods: Retrospective cohorts of pediatric emergency department patients at a single hospital (1993–2003) and from the National Hospital and Ambulatory Medical Care Survey (1992–2000) were used for analysis.
Results: Test ordering exhibits seasonal patterns, with monthly peaks in January and August (p < 0.0001). For the hospital cohort, the rate of cerebrospinal fluid pleocytosis exhibits seasonal patterns (p < 0.0001), with a peak from August to October. This is strongly associated with the rate and pattern of clinical neurologic disease (p < 0.0001). A long-term secular decline in daily test ordering is evident, dropping from 5.3 to 2.9 in the hospital sample, and from 371.8 to 185.3 in the national sample (p < 0.001). The long-term rate of pleocytosis has declined (p < 0.0001), though the yield of testing for pleocytosis has improved (p = 0.0104).
Conclusions: Laboratory test patterns correspond with those of clinical disease and are a promising source of surveillance data. Using such data for real-time monitoring requires specific adjustments for patient age, periodicities, and secular trends.
