A surveillance program for influenza A viruses (H5N1) was conducted in live bird and food markets in central Thailand during July 2006-August 2007. Twelve subtype H5N1 viruses were isolated. The subtype H5N1 viruses circulating in the markets were genetically related to those that circulated in Thailand during 2004-2005. 相似文献

Objectives: To evaluate the type of salvage treatment and outcomes of patients with locally advanced cervical cancer who failed treatment with concurrent chemoradiation with or without adjuvant chemotherapy. Methods: This was post hoc analyses of data from the randomized trial which included 259 patients who had FIGO stage IIB-IVA and had either pelvic radiation therapy concurrent with cisplatin followed by observation or paclitaxel plus carboplatin. Data of the patients who failed primary treatment were collected: type of salvage treatments, time to progress after salvage therapy, progression-free (PFS) and overall survivals (OS). Results: After primary treatment, 85 patients had either persistence (36.5%), progression (18.8%), or recurrences (44.7%). The sites of failure were loco/regional in 52.9%, systemic failure in 30.6%, and loco-regional and systemic in 16.5%. Chemotherapy was given in 51.8%, being the sole therapy in 34.1%. Majority were combination agents (31.8%), with paclitaxel/carboplatin as the most common regimen. Radiation to the metastatic sites along with chemotherapy was used in 14.1% whereas palliative radiation therapy or supportive care was used in approximately 10% of each. The median time from the start of salvage treatment to progression was 9.2 months (range 0.2-64.0 months) with median PFS of 11.2 months (95% CI, 7.2-15.3 months). Median overall survival 27.3 months (95% CI, 4.4-69.6 months). Conclusions: Chemotherapy, either alone or with radiation therapy, was the most common salvage treatment in LACC after failure from primary treatment. The time to progress and PFS were less than 1 year with OS of approximately 2 years. 相似文献

Hepatitis A is a disease commonly found in Thai children. However, there are very few reports on the age specific prevalence in Thailand. We studied the hapatitis A virus (HAV) antibody titer in a population in the rural eastern part of Thailand, using an antiHAV ELISA test (Abbott Laboratories, North Chicago Ill). Three hundred and sixty four subjects from Pong Nam Ron, Chanthaburi Province and 236 of children and adults from Bo Thong, Chon Buri Province were studied for age specific prevalence of antiHAV. The immunity against HAV increased with age. Fifty percent of Pong Nam Ron children had antiHAV antibodies at the age of 8-9 years and at the age of 12-13 years of Bo Thong children. The overall antibody prevalence rate was 67.9% in Pong Nam Ron and 59.3% in Bo Thong Districts. According to our data, less than 30 percent of children under 10 years old in the eastern part of Thailand were seropositive for HAV. This finding indicated a much lower incidence than previously reported which may reflect better personal and food hygiene. 相似文献

Purpose
To evaluate the sequence variations in the enhancer II (EnhII)/basal core promotor (BCP)/precore (PC) and X genes of hepatitis B virus (HBV) in Thai patients with hepatocellular carcinoma (HCC) by conducting a cross-sectional case–control study. 相似文献49.

Stored serum specimens, from four regions of Thailand, of healthy children attending well baby clinics and of healthy people with acute illnesses visiting outpatient clinics were randomly sampled and tested for IgG antibody to measles, mumps, and rubella (MMR). The immunity patterns of rubella and mumps fitted well with the history of rubella and MMR vaccination, seroprotective rates being over 85% among those aged over seven years. A high proportion of younger children acquired the infection before the age of vaccination. MMR vaccination should preferably be given to children at an earlier age. For measles, 73% seroprotective rates among children, aged 8-14 years, who should have received two doses of measles/MMR vaccine, were lower than expected. This finding was consistent with the age-group reported in outbreaks of measles in Thailand. The apparent ineffectiveness (in relation to measles) of MMR immunization of 1st grade students warrants further studies.Key words: Antibodies, Immunization, Measles, Measles vaccine, Mumps, MMR vaccine, Rubella, Seroepidemiologic studies, Seroprevalence, Vaccination, Thailand 相似文献

Detection of influenza virus types A and B and type A subtypes (H1, H3, and H5) by multiplex polymerase chain reaction 总被引:1,自引:0,他引:1
Boonsuk P Payungporn S Chieochansin T Samransamruajkit R Amonsin A Songserm T Chaisingh A Chamnanpood P Chutinimitkul S Theamboonlers A Poovorawan Y 《The Tohoku journal of experimental medicine》2008,215(3):247-255
Infections with influenza virus type A and B present serious public health problems on a global scale. However, only influenza A virus has been reported to cause fatal pandemic in many species. To provide suitable clinical management and prevent further virus transmission, efficient and effective clinical diagnosis is essential. Therefore, we developed multiplex PCR assays for detecting influenza types A and B and the subtypes of influenza A virus (H1, H3 and H5). Upon performing multiplex PCR assays with type-specific primer sets, the clearly distinguishable products representing influenza A and B virus were separated by agarose gel electrophoresis. In addition, the subtypes of influenza A virus (H1, H3 and H5), which are most common in humans, can be readily distinguished by PCR with subtype-specific primer sets, yielding PCR products of different sizes depending on which subtype has been amplified. This method was tested on 46 influenza virus positive specimens of avian and mammalian (dog and human) origins collected between 2006 and 2008. The sensitivity of this method, tested against known concentrations of each type and subtype specific plasmid, was established to detect 10(3) copies/microl. The method's specificity was determined by testing against other subtypes of influenza A virus (H2, H4 and H6-H15) and respiratory pathogens commonly found in humans. None of them could be amplified, thus excluding cross reactivity. In conclusion, the multiplex PCR assays developed are advantageous as to rapidity, specificity, and cost effectiveness. 相似文献
