Characteristics of antibody responses in tick-borne encephalitis vaccination breakthroughs

Tick-borne encephalitis (TBE) virus is an important human pathogenic flavivirus that is endemic in Europe and Asia. The disease can be effectively prevented by inactivated vaccines and vaccination breakthroughs (VBTs) are rare. We investigated the characteristics of antibody responses in such VBTs in comparison to those in unvaccinated TBE patients. In contrast to the unvaccinated controls, most of the VBTs displayed a delayed IgM antibody response and had high avidity and strongly neutralizing antibodies already in the first sample taken upon hospitalization. The antibody profile of these patients therefore had the characteristics of an anamnestic immune response. In the VBTs analyzed, immunological priming and memory were apparently not sufficient or fast enough to prevent the disease.

Report from the 1st Japanese Urological Association-Japanese Society of Medical Oncology joint conference, 2006: ''A step towards better collaboration between urologists and medical oncologists''

The 1st Japanese Urological Association-Japanese Society of Medical Oncology Joint Conference, titled 'A step towards better collaboration between urologists and medical oncologists', was held to coincide with the 44th Meeting of the Japan Society of Clinical Oncology, Tokyo, in October 2006. The main theme of the conference addressed the need for a subspecialty of medical oncologist within urology to keep abreast of advances in medical oncology. Urologists should become more involved in the postoperative management of urologic cancer. Consensus on the optimal way to move forward in the treatment of urological cancer is needed. The conference featured eight lectures surveying the present status of uro-oncology in Europe, the USA, Korea, Singapore, and Japan; the relationship between surgical oncologists and medical oncologists; global trends and international clinical trials in uro-oncology; and the future of urologic oncology. These were followed by a general discussion titled 'Achieving better collaboration between the surgical oncologist and the medical oncologist.' This report presents a roundup of the 1st Japanese Urological Association-Japanese Society of Medical Oncology Joint Conference.     

广西急性散发性病毒性肝炎的血清流行病学研究

对广西１６６例住院急性散发性病毒性肝炎病毒性肝炎病例进行血清流行病学调查研究，结果表明，甲型，乙型，丙型，戊型，庚型肝炎生期感染指标检出率分别为４．８２％，５１．２０％，１３．８６％和１１．６４％，未分病例占１７．４２％，危险性因素分析表明，乙肝、丙肝和庚肝病人中有较高的肝病史、输血史和手术史。认为乙肝在急性散病毒性肝炎中占重要地位，医源性传播是主要传播途径 。     

甘肃省1995年急性弛缓性麻痹病例病毒学监测

甘肃省１９９５年共报告１５岁以下儿童急性弛缓性麻痹（ＡＦＰ）病例９０例，发病率为１．３２／１０万。省脊髓灰质炎（脊灰）实验室收到ＡＦＰ病例的粪便标本共７９例，占８８％；双份合格粪便标本采集率为６８％（６１／９０）；粪便标本７天内送省脊灰实验室的占６５％（５２／７９）收到粪便标本后７天内分离培养的占８９％（７０／７９）；分离培养结果及时报告率为８７％（６９／７９）。病毒分离阳性率１３．９２％（１１／７９），其中脊灰病毒（ＰＶ）Ⅱ型５株，Ⅲ型１株，非脊灰肠道病毒（ＮＰＥＶ）５株。收到ＡＦＰ病例密切接触者粪便标本３ｌ８份，病毒分离阳性率５．６６％（１８／３１８），其中ＰＶⅡ型８株，ＮＰＥＶ１０株。全部送检粪便标本ＮＰＥＶ分离率３．７８％（１５／３９７）。所分离的ＰＶ均为疫苗株，且Ⅱ型居多。     

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.

Electroencephalographic changes in patients with herpes zoster

EEGs of 42 patients with herpes zoster and 6 with herpes zoster-associated encephalitis were studied to characterize the nature and prevalence of EEG abnormalities in apparently uncomplicated herpes zoster. Thirty-one percent of herpes zoster patients had EEG changes with reduced rhythm frequency ranging from 7 to 2 Hz activity. Frontotemporal localization was observed in 54% of the abnormal EEGs. When compared to EEG in herpes zoster associated encephalitis, the findings were qualitatively the same, but tended to be more severe in the encephalitis cases. No effect of acyclovir on the EEG could be demonstrated.     

Cholesterol-based personal risk assessment in coronary heart disease

Using data from the National Health and Nutrition Examination Survey (NHANES II) 1976-1980, we demonstrate how cross-sectional total serum cholesterol surveillance data can be used by an individual to assess current and future personal cholesterol risk status. We propose statistical models, based on a person's current measured cholesterol level and the relationship between cross-sectional age and cholesterol percentile estimates, that will allow prediction of future cholesterol levels or the age at which specified cholesterol risk levels will be reached if no cholesterol-altering intervention is taken. These models incorporate the observed variation in the NHANES II data and expected intraperson biological variation and intralaboratory analytical variation. We illustrate the adequacy of the models using data from the longitudinal Framingham Study.
