Acute epiploic appendagitis is an uncommon cause of abdominal pain resulting from appendageal ischemia caused by torsion or thrombosis of the draining vein. It is frequently misdiagnosed as acute appendicitis or diverticulitis. The coronavirus disease 2019 (COVID-19) pandemic has changed how this rare disease is diagnosed. There was a report of a young men diagnosed with COVID-19 and epiploic appendagitis as a rare cause of abdominal pain. In addition, a 50-year-old men was diagnosed with epiploic appendagitis during the treatment of COVID-19. This paper reports the case of a 53-year-old men who presented with right lower quadrant abdominal pain after COVID-19 and was diagnosed with acute epiploic appendagitis by computed tomography image findings. The thrombotic condition of COVID-19 may contribute to acute appendagitis, but more studies are needed to confirm this hypothesis.

PURPOSE: Encephalitis is an inflammation affecting brain parenchyma. At the time of presentation, it may be difficult to differentiate between viral encephalitis and altered mental status or seizures during febrile illness. The aim of the present study is to identify the predictive factors and to determine the prognostic factors of viral encephalitis in children presenting as seizure with fever. METHODS: From the retrospective review of the medical records, children with seizures or altered mental status during febrile illness who presented to Samsung Medical Center between January 2008 and May 2013 were included in the study. RESULTS: 81 patients were enrolled in this study (female:male=32:49). The mean age at admission was 4.9±4.3 years (range 0–14 years old). The patients were categorized into two groups according to the clinical diagnosis: (1) Viral encephalitis (VIRAL ENC, n=66), (2) Complex febrile seizures imitating viral encephalitis(C-FS, n=15). The predictive factors of viral encephalitis were focal and/or lateralized abnormalities in electroencephalography (EEG) (P<0.001). CONCLUSION: EEG can be helpful to predict the viral encephalitis, in pediatric patient who shows delayed restoration of consciousness after seizure during febrile illness.

Purpose:
The aim of this study was to compare changes of bite force, occlusal contact area, and dynamic functional occlusion analysis after occlusal stabilization splint therapy during sleep for one month in a patient with bruxism.
Materials and Methods:
From October 2021 to July 2022, sleep bruxism of 30 patients who visited the Department of Oral Medicine at Yonsei University College of Dentistry Hospital were recruited. The participants were divided into two groups: using an occlusal stabilization splint during sleep (treatment; n = 15) and not using an occlusal stabilization splint (control; n = 15). Before using the occlusal stabilization splint and one month after, bite force, occlusal contact area and dynamic functional occlusion analysis (ratio of left/right bite forces, average bite forces, maximum bite forces, and maximum contact areas during lateral and anterior and posterior mandibular movements) were performed.
Results:
There was no difference in bite force and occlusal contact area between the treatment group using the occlusal stabilization splint and the control group not using the occlusal stabilization splint during sleep for one month. However, there were significant differences in the average bite force and maximum bite force in the lateral and anterior and posterior mandibular movements and the maximum contact areas in the anterior and posterior mandibular movements.
Conclusion
The occlusal stabilization splint is helpful for sleep bruxism patients who lateral and anterior and posterior mandibular movements. In addition, further studies are needed a double-blind study with a large population.

Objective:
As part of an ongoing study, this study examined the impact of medications, such as heparin, aspirin, and sodium nitroprusside (SNP), on the factors linked to PTE after an intravenous injection of canine mesenchymal stem cell into experimental animals.
Methods:
Fluorescently labeled canine AdMSCs were administered intravenously into the tail veins of five-week-old male BALB/c hairless mice. This study compared the survival rates, biodistribution, platelet counts, D-dimer levels, and histological examination results among the drug treatment experimental and the control groups.
Results:
The final survival rates in the SNP, control aspirin, and heparin groups were 25%, 33%, 50%, and 100%, respectively. Ex vivo imaging confirmed fluorescence exclusively in the lungs of all subjects who died during the injection, with no fluorescence detected in the other organs. On the other hand, in the heparin experimental group, the surviving individuals exhibited fluorescence in the lungs and the liver on day one. Histological biopsies revealed PTE in all deceased individuals within the medication experimental groups (p = 0.029).
Conclusions
and Relevance: Heparin was highly effective, with no PTE-related deaths observed when used alongside cell injections. Aspirin revealed moderate effectiveness, surpassing the control group. On the other hand, the efficacy of SNP was inferior to that of the other two drugs.

The first case of human cryptosporidiosis was reported in Korea in 1995; however, an outbreak of Cryptosporidium has not been reported in Korea until now. This paper describes the first outbreak of cryptosporidiosis in Korea. On May 24, 2012, a local public health center filed a report on 126 residents with gastrointestinal symptoms in an old apartment complex in Seoul. Epidemiological investigations were implemented on 125 of the 126 patients. The patients were reported continuously over a period of 22 days. Diarrhea was the most common clinical symptom, and lasted for 5 days on average. The tap water was the only common exposure of the patients. During the environmental investigation it was discovered that the water and septic tanks were situated closely and that the waste water pipes were corroded where they passed over the water pipes. Cryptosporidium parvum was detected in 3 of the 7 stool specimens by PCR-RFLP. A number of Cryptosporidium oocysts were also detected in the water specimens from the water tank. In conclusion, Cryptosporidium parvum was the key causal pathogen of this outbreak. It is presumed that the tap water was contaminated by a sewage leak from the aged pipelines.
