Isolated gastric varices (IGV) can occur in patients with left-sided portal hypertension resulting from splenic vein occlusion caused by thrombosis or stenosis. In left-sided portal hypertension, blood flows retrogradely through the short and posterior gastric veins and the gastroepiploic veins, leading to the formation of an IGV. The most common causes of splenic vein occlusion are pancreatic diseases, such as pancreatic cancer, pancreatitis, or a pseudocyst. However, various other cancers, such as colon, gastric, or renal cancers, have also been known to cause splenic vein occlusion. Our patient presented with a rare case of IGV bleeding induced by splenic lymphoma-associated splenic vein occlusion. Splenectomy, splenic artery embolization, and stenting of the splenic vein are the current treatment choices. Chemotherapy, however, is an alternative effective treatment for splenic vein occlusion caused by chemotherapy-sensitive tumors. Our patient responded well to chemotherapy with a cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisolone regimen, and the splenic vein occlusion resolved after the lymphoma regressed.

Early initiation of enteral nutrition improves clinical outcomes in critical patients with serious burns. Postpyloric tube feeding is a valuable therapeutic option for severely burned patients with poor gastric emptying. How early post-pyloric feeding can be initiated to provide more benefits to patients has not yet been examined. A fire erupted at a recreational water park in New Taipei City, Taiwan, on June 27, 2015. The results of early initiation versus delayed post-pyloric feeding in severely burned patients in this masscasualty incident were compared. Door-to-post-pyloric feeding time ≤ 24 h was considered as early postpyloric feeding (EPF) and that > 24 h was considered as delayed post-pyloric feeding (DPF). Thirteen patients with severe burn injuries (> 40% of the total body surface area) were assigned to undergo either EPF (five patients) or DPF (eight patients). This study is a "fortuitously controlled" study, and the authors were able to formulate and test whether EPF is better than DPF by comparing the two groups. In patients in the EPF, the intake of calories increased rapidly and was maintained throughout the study period. In addition, rapid restoration of plasma magnesium concentrations as well as pronounced recovery of platelet count in the EPF group was observed. In conclusion, our findings indicate that the time from injury to the onset of post-pyloric feeding is crucial, and EPF allows for the administration of calculated caloric needs. Therefore, EPF can be successfully initiated with beneficial outcomes of nutritional reconstruction in severely burned patients.

The risk of the geographic transmission of emerging infectious diseases through air travel varies greatly. In this study, we collected data on cases of food-borne diseases between the years 2011 and 2020 in Taiwan to access the epidemiological features, differences, and trends in domestic and imported cases of typhoid and paratyphoid in terms of patient sex, age, month of confirmation, and area of residence. In this study, we made use of the open data website provided by Taiwan’s Centers for Disease Control (TCDC) to extract the reported numbers of cases of typhoid and paratyphoid between January and December from 2011 to 2020 for comparison. Univariate analysis was performed using the Chi-square test for categorical variables. Fisher’s exact test was performed if an expected frequency was less than 5. A total of 226 typhoid cases and 61 paratyphoid cases were analyzed from the database. The incidences of typhoid and paratyphoid per million of the population were 0.42–2.11 and 0–0.39, respectively. There was a significant difference in the incidence of the diseases between the age groups (p= 0.019), with a gradual increase in the 20–40 years group. A distinct seasonal (between fall and spring) variation was also observed (p= 0.012). There were 34 cases of children with typhoid in the period 2011–2015 and 12 cases of children with typhoid in the period 2016–2020. During these periods, there were two cases of paratyphoid. This study indicated that the risk of children suffering from typhoid has been significantly reduced in the last five years. Furthermore, we found that more women have acquired typhoid and paratyphoid than men, and that living in the Taipei metropolitan area and the northern area was a potential risk factor. Furthermore, the number of imported cases of typhoid (n = 3) and paratyphoid (n = 0) reported during the COVID-19 pandemic was lower than that reported for the same disease from 2011 to 2020. More typhoid and paratyphoid cases were imported from Indonesia, India, Myanmar, and Cambodia. This study represents the first report on confirmed cases of acquired typhoid and paratyphoid from surveillance data from Taiwan’s CDC for the period 2011–2020. This study also demonstrates that the cases of typhoid and paratyphoid decreased in Taiwan during the COVID pandemic. Big data were used in this study, which may inform future surveillance and research efforts in Taiwan.

Acute diarrhea is mainly caused by norovirus and rotavirus. Numerous factors modify the risk of diarrhea cluster infections and outbreaks. The purpose of this study was to explore the epidemiological characteristics, differences, and trends in the distribution of viral and bacterial pathogens that cause diarrhea cluster events as well as the public places where diarrhea cluster events took place in Taiwan from 2011 to 2019. We examined publicly available, annual summary data on 2865 diarrhea clusters confirmed by the Taiwan Centers for Disease Control (CDC) from 2011 to 2019. There were statistically significant differences (p < 0.001) in event numbers of diarrhea clusters among viral and bacterial pathogens, and statistically significant differences (p < 0.001) in event numbers of diarrhea clusters among bacterial pathogens. There were also statistically significant differences (p < 0.001) in the event numbers of diarrhea clusters among public places. Norovirus infections were the first most numerous (77.1%, 1810/2347) diarrhea clusters among viral and bacterial infections. Among bacterial infections, Staphylococcus aureus infections accounted for the greatest number of diarrhea clusters (35.5%, 104/293). Schools were the places with the greatest number of diarrhea clusters (49.1%, 1406/2865) among various institutions. Norovirus single infection (odds ratio, OR = 4.423), Staphylococcus aureus single infection (OR = 2.238), and school (OR = 1.983) were identified as risk factors. This is the first report of confirmed events of diarrhea clusters taken from surveillance data compiled by Taiwan’s CDC (2011–2019). This study highlights the importance of long-term and geographically extended studies, particularly for highly fluctuating pathogens, to understand the implications of the transmission of diarrhea clusters in Taiwan’s populations. Importantly, big data have been identified that can inform future surveillance and research efforts in Taiwan.
