A cross-sectional survey of 327 Japanese short-term travelers (≤3 weeks) arriving in Bangkok, Thailand was conducted to assess the incidence of travelers’ diarrhea (TD) as well as their symptoms and treatment-seeking behaviors. The incidence of the first episode of TD (FTD) was ascertained retrospectively by questionnaire. Reported by 69 travelers, FTD clustered within the first 8 days of arrival in Thailand, and the incidence rate varied from 2% to 8% with the highest incidence on the third day.
Cumulative probability of FTD was 19% for those arriving in Thai directly from Japan, 42 % for those arriving via Southeast Asia, and 25% for those arriving via other regions at Day 7 by the Kaplan-Meier survival analysis. Log rank test revealed a higher FTD risk for travelers arriving via other Southeast Asian countries than for those arriving directly from Japan (P < 0.005). Of all the 69 FTD episodes, 33% had classic TD defined as ≥3 unformed stools per 24 hours with at least one accompanying symptom, 49% had moderate TD defined as ≤2 unformed stools with at least one additional symptom or more unformed stools without additional symptoms, and 17% had mild TD defined as with ≤ 2 unformed stools without additional symptoms. Cumulative probability of FTD at Day 7 was 12% for classic TD, 25% for classic plus moderate TD and 30% for all the TD. More than 38% of travelers with diarrhea took medicine brought from Japan. Among travelers with classic TD, 35% bought medicine in Thailand, whereas 47-50% of travelers with moderate and mild TD took only rest without any treatment.

We report a case of a 40-year-old male with mycosis fungoides who was successfully treated with traditional herbal (Kampo) medicine in addition to Western medicine-including electron beam therapy and local injections of IFN-γ. In December 1991, he noticed erythema on his upper extremities, and the eruptions gradually worsened. In July 1997, various-sized skin tumors appeared on his trunk. He was diagnosed as being at the tumor stage of mycosis fungoides on the basis of a histological examination.
In September1997, he was referred to our department and was treated with Jumi-haidoku-to, Takuri-shodoku-in, Naitaku-san, Kyuki-kyogai-to, etc., for his skin lesions. When he felt thirst and heat from the irradiation, he was given Byakko-ka-ninjin-to. He also received Ohgi-kenchu-to for diarrhea and general malaise. He is currently receiving IFN-γ and immunotherapy at the department of dermatology, and his condition is good. Careful follow-up will be necessary. It is thought that the traditional herbal medicines are useful for the treatment of mycosis fungoides.

Background: Laparoscopic gastrectomy has several difficult points including,lymph node dissection and resection of several blood vessels for trainee surgeons.Recently, preoperative evaluation of vasculature based three-dimensional (3D)imaging technique resulted in a significantly improved clinical outcome inabdominal surgery. The aim of this study is to investigate the usefulness of the 3Dimage in laparoscopic gastrectomy for trainee surgeons.Method: We adopted a multiphase CT protocol to acquire 3 image sets (arterial,portal, and equilibrium phases). 3D-reconstruction of gastric vasculature wasmade using data from a contrast enhanced MDCT and SYNAPSE VINCENTsoftware. Whole pancreas, spleen, gastric vasculature were extracted from MDCTscans and traced. Thirty three patients, who underwent laparoscopic gastrectomyfor gastric cancer during the period between Jan 2013 and May 2014 wereexamined in this study. Four trainees performed a 19 laparoscopic gastrectomy,while 14 laparoscopic gastrectomy were conducted by the two trainers. Thesurgical outcomes in both groups and the pattern of gastric vasculatures wereevaluated.Result: 3D imaging technique showed a correct positional relationship betweenthe stomach, gastric vessels, pancreas and spleen. Surgical outcome includingestimated blood loss, and operative time in trainee group were not significantlydifferent compared to trainer group. 3D imaging technique showed a correctpositional relationship between the stomach, gastric vessels, pancreas and spleen.Regarding vascular pattern detected by 3D imaging, the origins of IPA were RGEAin 12 cases (36%), GDA in 8 cases (24%).bifurcation of RGEA and GDA in7 cases(21%), and not detected in 1 case (3%), respectively. The types of confluence ofIPV were RGEV in 16 cases (48%), ASPDV in 10 cases (30%), and not detectedin 7 cases (21%), respectively.Conclusions: 3D imaging technique might contribute to successful laparoscopicgastrectomy. Preoperative 3D-simulation techniques enabled trainee surgeons toeasily and safely perform laparoscopic gastrectomy.

The effect of mass treatment on questionnaire results in the diagnosis of schistosomiasis mansoni was examined in 267 school children in an endemic area of Tanzania by Kato-Katz analysis of fecal specimens. The questionnaire asked for information about self-diagnosis, abdominal symptoms, blood in stools, history of wild water contact, stool examination and medication for schistosomiasis, and knowledge of the disease. A logistic regression analysis disclosed a significant association between schistosomiasis and "diarrhea" (p ≈ 0.007; odds ratio, 32.0; confidence interval, 2.5 - 403.3) and "abdominal enlargement" (p ≈ 0.003; odds ratio, 15.2; confidence interval, 2.6 - 90.1) among 61 children who had no history of medication for schistosomiasis. The sensitivity and specificity of the model were 86% and 64%, respectively. In contrast, no significant correlation was observed either for the 116 treated children, or for all the 267 children after the mass treatment. We conclude, therefore, that for children who had no history of medication for schistosomiasis, the questionnaire for abdominal manifestations provides reliable information on S. mansoni infection. However, once a child takes medication, the questionnaire becomes unreliable. This observation suggests that immunomodulation by anti-schistosomiasis drugs that kill adult worms exerts an effect on the appearance of abdominal manifestations and might explain the ambiguity of clinical symptoms in chronically infested patients, except in terminal cases. Further studies are required to develop a simple, rapid and cost-effective diagnostic method for monitoring S. mansoni infection after medication in local areas without resort to laboratory-based identification of schistosomiasis.

A biocontainment facility is a core component in any research setting due to the services it renders towards comprehensive biosafety observance. The NUITM-KEMRI P3 facility was set up in 2007 and has been actively in use since 2010 by researchers from this and other institutions. A number of hazardous agents have been handled in the laboratory among them MDR-TB and yellow fever viruses. The laboratory has the general physical and operational features of a P3 laboratory in addition to a number of unique features, among them the water-air filtration system, the eco-mode operation feature and automation of the pressure system that make the facility more efficient. It is equipped with biosafety and emergency response equipments alongside common laboratory equipments, maintained regularly using daily, monthly and yearly routines. Security and safety is strictly observed within the facility, enhanced by restricted entry, strict documentation and use of safety symbols. Training is also engrained within the operation of the laboratory and is undertaken and evaluated annually. Though the laboratory is in the process of obtaining accreditation, it is fully certified courtesy of the manufactures’ and constructed within specified standards.

Pathogens handled in a Biosafety Level 3 (BSL-3) containment laboratory pose significant risks to laboratory staff and the environment. It is therefore necessary to develop competency and proficiency among laboratory workers and to promote appropriate behavior and practices that enhance safety through biosafety training. Following the installation of our BSL-3 laboratory at the Center for Microbiology Research-Kenya Medical Research Institute in 2006, a biosafety training program was developed to provide training on BSL-3 safety practices and procedures. The training program was developed based on World Health Organization specifications, with adjustments to fit our research activities and biosafety needs. The program is composed of three phases, namely initial assessment, a training phase including theory and a practicum, and a final assessment. This article reports the content of our training program.
