Chronic diarrhea in children is a common problem with numerous causes. Although most of these causes are benign, critical illness may present as chronic diarrhea. In a patient of chronic diarrhea, gastrointestinal infections are the most common causes in children of all ages and antibiotics may cause chronic diarrhea by altering intestinal microflora, which can result in the emergence of bacterial overgrowth. Overgrowth of Clostridium difficile may cause pseudomembranous colitis. We experienced 25-month-old boy who suffered from chronic diarrhea and partially treated with antibiotics irregularly. Colonoscopic findings of this child showed multiple plaques with white to yellowish exudate which adhere to the mucosal surface of a variable length of rectum. Histollogically, each plaque comprised a pseudomembrane of mucous debris, inflammatory cells, and exudate overlying groups of partially disrupted glands. A latex agglutination test on patient's stool was positive to toxin A of Clostridium difficile. He was recovered after stopping the antibiotics he has been prescribed, and being given vancomycin for 2 weeks. We report this case with brief review of literature.

Q-35의 일회 및 반복투여 연구결과, 자타학 증상은 단지반복투여 피험자에서 중등도의 두통(1예)과 설사(3예)가 관찰되었으나 이들 설사증례는 장내 세균총 검사상 복감염에 의한 것이 아니었다. Q-35 투여 후 Q-EEG 및 평행기능의 장애 등은 관찰되지 않았으며 임상화학 검사상 반복투여 3예에서 SGOT, SGPT의 경미한 상승을 보였으나 이러한 변화는 정상 범위내에서의 변화이었다. Q-35의 반복투여에 따라 투약 3일에서 8일에 걸처 장내세균총은 일부 호기성 및 혐기성 세균총의 감소를 보였으나 투약종료 10일 후에는 투약전 상태로 회복되었다. Q-35는 투여량의 약 70 % 가 24시간 뇨중으로 배설되었으며 일회 및 반복투여의 결과 용량의존적인 동태양상은 관찰할 수 없었다. 50 mg에서 400 mg까지 일회 투여시 5.6-7.1 시간의 혈장반감기를 보였으며, 반복투여 시험에서는 평균 5.6 $\pm$ 0.7 시간의 반감기를 보였다. Q-35는 타액내로 신속히 이행되었으며 타액내 AUC는 혈장 AUC의 약 75 %에 해당하였고, 식사에 의해 약간의 흡수속도지연(Cmax 0.4 시간지연)과 공복시에 비해 82 %의 상대적 생체이용율을 보였다.

Purpose: The purpose of this study was to investigate the difference in the incidence of diarrhea among the subjects given hypertonic and isotonic nutrients to the nasogastric tube feeding patients in the a critical care setting. Methods: This study is aquasi-experimental study with a pre & post-test design. The sample size of 40 was calculated based on Cohen's formula (1988). The total of 40 subjects who signed the informed consent were randomly selected and divided evenly into two groups, experimental and control group. Results: There are no significant differences between the two groups in homogeneity test (sex, age, albumin level, the use of antibiotics, antacid, and $H_2$ blocker). However, the frequencies of occurrence in diarrhea according to the density of nutrients formulation indicated a statistical difference at the level of .005 (p=.001): diarrhea occurred in four of 20 (20%) of the experiment group, but 14 (70%) of the control group. Also the onset date of diarrhea in the experiment group is later than that of the control group. Conclusion: The research findings suggest that we should begin with low density nutrients for nasogastric tube feeding, and increase its density gradually to decrease diarrhea incidence in the critical care setting.

The purpose of this study was to establish early diagnosis for bovine virus diarrhea-mucosal disease(BVD-MD) Two Holstein among 22 breeding cows were shown ulcer in the mouth and watery diarrhea. Diarrheal feces and ulcerous lesion of the mouth from 2 cows were sampled for detection of viral antigen. BVD virus was isolated by inoculation of the samples to MDBK cells, and the cytopathic effects were observed in cultured MDBK cells which inoculated with virus isolates from the feces. Viral antigens were detected in the feces and ulceruous lesion by immunogold staining. The serum neutralization titers were shown 1 : 64 or greater in 8 blood samples by using BVD virus (NADL strain). By the RT-PCR, using reverse primer 5'-ACTCCATGTGCCATGTACAG-3', forward primer 5'-ACTCCATGTGCCATGTACAG-3', 285 base pair band specific to BVD virus was detected. In conclusions, the results of above tests which executed using the diarrheal feces and ulcerous lesion of the mouth and the isolates were conformed as BVD virus.

Shiga-like toxin-II(SLT-II)-producing Escherichia coli 0157 : H7 strain B2387이 분비하는 SLT-II가 gnotobiotic자돈에서의 뇌혈관 병변을 일으키는 pathogenesis에 관해서 실험을 했다. 제왕절개 수술로 태어난 자돈들을 두 그룹으로 나누어서, 한 그룹에는 SLT-II 중화항체를 포함한 혈청을 구강을 통해서 수동면역을 시키고, 또다른 한 그룹에는 SLT-II 중화항체가 포함되어 있지 않은 혈청을 구강을 통해서 수동면역시켰다. 24시간후 두 그룹 모두에게 SLT-II producing Escherichia coli O157 : H7 strain B2387를 구강으로 접종했다. SLT-II 중화항체가 포함되어 있지 않은 혈청으로 수동면역시킨 그룹의 자돈들은 설사와 맹결장염, 신경증상, 뇌혈관병변을 일으키고, plasma의 prostacyclin의 level이 증가했다. 하지만 SLT-II 중화항체가 포함되어 있는 혈청으로 수동면역시킨 그룹의 자돈들은 설사와 맹결장염은 유발했지만, 신경증상과 뇌혈관병변은 관찰되지 않았고, prostacyclin의 level도 증가하지 않았다. 이런 실험결과는 SLT-II 중화항체는 뇌혈관병변은 방어하지만 맹결장염은 방어하지 못한다는 의미를 나타내며, prostacylin의 증가는 뇌혈관의 endothelium의 병변을 의미한다.

In 2011, several herds in Youngju city in Gyeongbuk province underwent an outbreak of bovine viral diarrhea virus (BVDV) causing high morbidity and mortality. Genetic analysis revealed that two subgenotypes of BVDV-1b (n = 21) and BVDV-2a (n = 7) were identified. The BVDV-1b subgenotype was most frequently detected from our field cases and BVDV-2a subgenotype was also identified in this outbreak. These BVDV-1b infections showed severe acute clinical manifestations similar to BVDV-2 infection. This result reports the detection of BVDV-1b associated with an acute and fatal outbreak of BVDV in Korean indigenous calves.

Acrodermatitis enteropathica, an autosomal recessive disease, usually presents with severe acral and circumorificial dermatitis, diarrhea, alopecia, intercurrent bacterial infection during early infancy, and is eventually fatal if left untreated. We report a case of acrodermatitis enteropathica in a 2-month-old male infant who presented with chronic diarrhea not responsive to conventional therapy and developed disseminated intravascular coagulation (DIC). He showed the characteristic eczematoid skin lesions, chronic diarrhea, failure to thrive, and low serum zinc concenturation. $Zn^{2+}$ was administered with dramatic improvement of skin lesions, DIC and diarrhea. He rapidly catched up normal growth and development on continuing zinc supplementation.

Purpose: The purpose of this study was to investigate incidence and factors related to diarrhea in an intensive care unit (ICU). Methods: Retrospective correlational design was used. Data were collected from reviewing medical records of 210 patients stayed at an ICU in one university hospital, Seoul. Patients were included in the study if they 1) had no gastrointestinal disorders or fecal incontinence before coming to the ICU, 2) stayed longer than 5 days at the ICU, 3) were not on stool softners, 4) were without abdominal surgery, and 5) were 20-year-old or older. Results: The incidence of diarrhea was 27.1%. Durations of ICU stay, antibiotics administration, and enteral feeding were found to be statistically significant factors correlated with diarrhea. The enteral feeding was the significant predictors of the diarrhea in ICU. Conclusion: Since characteristics of diarrhea in ICU patients is shown to be multifactorial, nursing strategies for evaluating and managing related factors are recommended.

Purpose: This study was done to examine incidence of diarrhea and explore factors influencing occurrence of diarrhea in patients admitted to intensive care units (ICU). Methods: For this retrospective research, data based on inclusion criteria were collected from the electronic medical records for 142 patients admitted to a university hospital ICU from September 2014 to August 2015. Statistical analysis was conducted using SPSS/WIN 22.0 program. Results: Incidence of diarrhea was 53.5% during the 12-month study period. Diarrhea occurred at 4.54 days and continued for 1.79 days on average. Average total frequency of diarrhea was 5.56 times. Increased ICU stay, enteral nutrition, and infection state were significant predictors of the occurrence of diarrhea. Infection increased risk of diarrhea 3.4 times and enteral nutrition increased risk of diarrhea to 2.2 times greater than patients not receivng enteral nutrition. Conclusion: Diarrhea in ICU patients is associated with multiple factors that should be considered to implement preventive strategies. Infection control should be emphasized, and close monitoring of diarrhea should be provided for those with enteral nutrition. Further studies are warranted to determine standardized clinical definition of diarrhea and diarrhea risk factors in ICU patients with different levels of severity and comorbidity.
