Our case illustrates the potential risks of DFRA-induced renal toxicity, hepatic dysfunction, and thrombocytopenia. Meticulous monitoring of kidney, liver, and hematopoietic function is mandatory for patients undergoing treatment with DFRA. Further investigation of the potential risk and adverse effects of long-term DFRA use is necessary.
In respond to acute flaccid paralysis (AFP) in association with Enterovirus D68 (EV-D68) infection, Taiwan Centers for Disease Control began to screen EV-D68 infection among each AFP patient since July 2015 and detected the first case in August 2016. This article updated the molecular epidemiology trends of EV-D68 from the national surveillance data.
Abstract. An unprecedented dengue outbreak involving more than 15,000 infections, including 136 dengue hemorrhagic fever (DHF) cases and 20 fatalities, occurred in Taiwan in 2014. The median age of the DHF cases was 71 years (range: 4-92 years) and most of them (N = 100, 73.5%) had comorbidities, of which the majority were hypertension (56%) and diabetes mellitus (DM; 27%). Only approximately half of the DHF cases (59/136) were classified as severe dengue, based on the 2009 WHO-revised dengue classification. The fatality rate for this DHF outbreak was 14.7%. DM (odds ratio [OR] = 3.60, 95% confidence interval [CI] = 1.22-10.63) and presentation with severe plasma leakage (OR = 6.42, 95% CI = 1.76-23.63) were independent risk factors for fatality.
BackgroundOn 5 March 2015, Taiwan Centers for Disease Control was notified of more than 200 students with gastroenteritis at a senior high school during excursion to Kenting. We conducted an outbreak investigation to identify the causative agent and possible vehicle of the pathogen.MethodsWe conducted a retrospective cohort study by using a structured questionnaire to interview all students for consumed food items during their stay at the resort. Students were defined as a gastroenteritis case while having vomiting or diarrhea after the breakfast on 4 March. We inspected the environment to identify possible contamination route. We collected stool or vomitus samples from ill students, food handlers and environmental specimens for bacterial culture for common enteropathogens, reverse transcription polymerase chain reaction (RT-PCR) for norovirus and enzyme-linked immunosorbent assay (ELISA) for rotavirus. Norovirus PCR-positive products were then sequenced and genotyped.ResultsOf 267 students enrolled, 144 (54%) met our case definition. Regression analysis revealed elevated risk associated with iced tea, which was made from tea powder mixed with hot water and self-made ice (risk ratio 1.54, 95% confidence interval 1.22–1.98). Ice used for beverages, water before and after water filter of the ice machine and 16 stool and vomitus samples from ill students were tested positive for norovirus; Multiple genotypes were identified including GI.2, GI.4 and GII.17. GII.17 was the predominant genotype and phylogenetic analyses showed that noroviruses identified in ice, water and human samples were clustered into the same genotypes. Environmental investigation revealed the ice was made by inadequate-filtered and un-boiled water.ConclusionsWe identified the ice made by norovirus-contaminated un-boiled water caused the outbreak and the predominant genotype was GII.17. Adequately filtered or boiled water should be strongly recommended for making ice to avoid possible contamination.
BackgroundHuman granulocytic anaplasmosis, a tick-borne infection caused by Anaplasma phagocytophilum, has received scant attention, while scrub typhus, a mite-transmitted disease caused by Orientia tsutsugamushi, is the most common rickettsiosis in Taiwan. The clinical presentations of both diseases are characterized by undifferentiated fever, headache and malaise. Moreover, both pathogens have been detected in small mammals that serve as hosts for chiggers and ticks in the wild. The objective of the present study was to investigate whether human granulocytic anaplasmosis occurs in Taiwan.Methodology/Principal findingsBlood samples from 274 patients suspected of having scrub typhus in Kinmen, an offshore island of Taiwan, in 2011 and 2012 were retrospectively examined by immunofluorescence assays. IgG antibodies reactive with Anaplasma phagocytophilum was found in 31.8% (87/274) of the patients. Paired serology identified 3 patients with human granulocytic anaplasmosis and 8 patients with coinfection with O. tsutsugamushi and A. phagocytophilum. Laboratory tests showed that elevated serum ALT/AST, creatinine, and BUN levels were observed in patients with anaplasmosis and coinfection, but elevated serum CRP levels, thrombocytopenia, and anemia were only observed in coinfected patients. PCR detected A. phagocytophilum 16S rDNA and p44/msp2 in 2 patients. The phylogenetic analysis suggested that the replicons of the 16S rDNA shared high sequence similarity with the reference sequences in the Korea, USA, Japan, and China. The amplicons of p44/msp2 were close to those of the human variants identified in the USA and Japan.ConclusionsOur findings indicated that A. phagocytophilum infection was prevalent but unrecognized in Taiwan.
We investigated a cluster of SARS-CoV-2 infections in a quarantine hotel in Taiwan in December 2021. The cluster involved 3 case patients who lived in nonadjacent rooms on different floors. They had no direct contact during their stay. By direct exploration of the space above the room ceilings, we found residual tunnels, wall defects, and truncated pipes between their rooms. We conducted a simplified tracer-gas experiment to assess the interconnection between rooms. Aerosol transmission through structural defects in floors and walls in this poorly ventilated hotel was the most likely route of virus transmission. This event demonstrates the high transmissibility of Omicron variants, even across rooms and floors, through structural defects. Our findings emphasize the importance of ventilation and integrity of building structure in quarantine facilities.
Purpose: This study aimed to evaluate the quality performance of digital mammographic systems based on the national survey data in Taiwan. Methods: On‐site inspections were conducted on 120 mammographic units during 2014 survey in Taiwan. Quality performance of digital mammographic systems evaluated by DIGIMAM phantom (Artinis) complied with the European guidelines for quality assurance program were performed on 56 digital units, including 35 CR and 21 DR systems. The phantom was exposed with clinical techniques on‐site for further investigate geometric distortions, contrast‐to‐noise ratio (CNR) and signal‐to‐noise ratio (SNR) with for‐processing images, and dynamic range and chest wall missed tissue with for‐presentation images. Results: Geometric distortion ranged from 0.3%∼12.5% for chest wall‐anterior and from 0.8%∼14.1% for left‐right direction. Mean CNR for 0.1 mm and 0.2 mm Al were 0.06±0.02 and 0.11±0.04, respectively. SNRs for DR may deviate from systems of different manufacturer/model and had a mean value of 69.87±15.02. As for CR systems, larger SNR variations were found between different manufacturers as compared to DR ones. For investigating the dynamic range in the low contrast inserts within fatty, normal and dense tissue, only 4 of 10 Hologic systems failed to distinguish the inserts for all the three test patterns. Evaluations of missed tissue at chest wall side showed that most DR systems had missed tissue less than 5 mm with the exception of 2 Hologic systems. Total pass rate according to European guidelines for chest wall missed tissue was 84.78%. Conclusion: Feasibility for quality survey using commercialized digital phantom were investigated in this study. Further analysis may be performed and more systems may be included in the survey in the future. The results may provide as a reference for digital mammography quality assurance program established in Taiwan.
