Herpes simplex esophagitis can occur in those with normal immune function, but is more often seen in those who are immunocompromised. In one series, 5 percent of post-kidney transplant recipients had herpes esophagitis. We experienced a case of herpes simplex esophagitis, following renal transplantation in a 9 year old male. He complained of epigastric pain, nausea and blood-tinged vomiting. Endoscopic examination showed volcano ulcer, mucosal friability and multiple confluent ulcers covered by whitish exudates on elevated margin in the middle and lower esophagus. Microscopic findings revealed multinucleated giant cells, margination of chromatin, intense nonspecific inflammation and strong positive for herpes simplex virus immunohistochemical staining. Esophageal lesions and symptoms improved after acyclovir therapy.

BACKGROUND/AIMS: Intestinal lymphangiectasia is a disease characterized by dilated lymphatics of the intestinal mucosa and excessive enteric loss of plasma proteins. Instead of multiple blind peroral jejunal biopsy, duodenal endoscopy and endoscopic small bowel biopsy were performed. We evaluated the significance of endoscopic small bowel biopsy and the usefulness of the other diagnostic methods in the diagnosis of intestinal lymphangiectasia in children. METHODS: Fourteen children seen between August 1989 and August 1997 with clinically suggestive intestinal lymphangiectasia were analysed. The median age at onset of symptoms was 4 years. Primary intestinal lymphangiectasia occurred in 10 children and secondary intestinal lymphangiectasia occurred in 4 children, of whom two had Fontan operation, one had constrictive pericarditis, and one had Crohn's disease. Low fat, high protein diet with medium chain triglycerides was the mainstay of treatment. RESULTS: 1) Diarrhea was present in 14 patients, and edema in 11 patients. Hypocalcemic tetany occurred in 6 children and vomiting in 5 children. Dight children had ascites and three of these had chylous ascites. Growth retardation was present in four patients, chylothorax in one, and lymphedema in one. The initial serum albumin concentration was 1.8 g/dl, the serum calcium level 6.7 mg/dl, and the total lymphocyte count 623 /mm(3). 2) Dilated lymphatics in the small bowel mucosa was confirmed by endoscopic biopsy in 14 children(100%). The sensitivity of alpha1-antitrypsin clearance was 100%. Duodenal endoscopy showed scattered white spots covering mucosa in 11 children(79%). Small bowel series revealed thickened mucosal folds in 10 children(77%). Four(31%) had positive finding of 99mTc-antimony lymphoscintigraphy. 3) Responses to treatment in children with primary intestinal lymphangiectasia were graded as good if the symptoms resolved, and poor if there was no lasting resolution of symptoms and repeated albumin administration. Response to therapy was good in four and poor in six patients. The mean age at onset of symptoms was 8 years in good resonse group, and 2 years in poor response group (p<0.05). CONCLUSION: The diagnosis of intestinal lymphangiectasia is confirmed by duodenoscopy and endoscopic small bowel biopsy in a child with diarrhea, edema, hypoalbuminemia, and lymphocytopenia. As compared with other diagnostic methods such as small bowel series and lymphoscintigraphy, duodenoscopy and endoscopic small bowel biopsy are very sensitive and should be performed early.

A twenty four-year-old female patient had suffered progressive dyspnea for 6 years until death. She denied any symptoms suggestive of connective tissue disease, or deep vein thrombosis. She suffered an episode of pontine infarct in 1995. Four years after diagnosis of primary pulmonary hypertension, she died of sudden death during hospitalization. Gross features of pulmonary arteries at autopsy were as follows: left main pulmonary artery showed dilation of the lumen and thickening of the wall, and right main pulmonary artery was markedly dilated and contained fresh thrombus. Hematoxylin and eosin-stained sections of lung tissue showed plexiform lesions of pulmonary arteries, complete luminal obliteration of pulmonary arterioles and dilated lesion of pulmonary arterioles, and capillaries. This patient represents a typical case with a primary pulmonary arteriopathy with plexiform lesions with thrombotic lesion, demonstrating the importance of thrombosis in situ in the pathogenesis of primary pulmonary hypertension. To our knowledge, this is the first autopsy report on the primary pulmonary hypertension in Korea.

BACKGROUND: Unexpected deaths of the patients at ED are surprising to the medical staffs as well as the families. It may also increase the possibilities of medico-legal problems. This study was conducted to review the unexpected death in ED and find the predictive factors leading patients to unexpected death. METHODS: A retrospective study with reviewing available medical records of 183 patients who were expired at ED of Shinchon Severance Hospital from Mar. 1997 to Feb. 1998 and 103 patients of Youngdong Severance Hospital from Mar. 1996 to Feb. 1998 was done. Analyses were 4one on 30 variables of physical findings, laboratory results, procedures and therapies. We used univariate analysis, such as t-test and x2-test and multiple logistic regression analysis. RESULTS: Of the total 286 deaths in ED, 153 cases were enrolled in this analysis. The number of unexpected deaths were 76. Age, mental status, fraction of neutrophil count, BUN level, whether endotracheal incubation was done, use of inotropics were the factors with statistical ,significance on the univariate analysis, but only comatose mentality, endotracheal incubated case, and use of the inotropics were significant on logistic regression analysis. The longer the ED length of stay, the higher the rate of mortality and unexpected death. CONCLUSION: This result suggest that medical attention is needed on the patients with comatose decreased mental stylus, endotracheally intubated case and needing inotropic agents to prevent unexpected deaths. Shortening the ED length of stay may also be a factor for decrease the unexpected death rate.

Serological prenatal screening tests are widely used to detect fetal chromosomal abnormalities such as Down and Edward syndromes. Amniocentesis is conducted as a confirmatory test in the screening-positive case. After discovering of presence of fetal cell-free DNA in maternal blood, non-invasive prenatal test (NIPT) coupled with next generation sequencing are performed in abroad. Results of genomics-based NIPT results supplied to Labgenomics laborotory from June, 2013 to August, 2014 were analyzed. Maternal blood samples were collected into specific Cell-Free DNA BCT tube and were transported. The samples were then delivered to Ariosa Diagnostics by FEDEX. Fetal cell-free DNA samples were analyzed using the Harmony test with sequencing of relevant chromosomes and by using the FORTE (fetal-fraction optimized risk of trisomy evaluation) algorism at Ariosa Diagnostics. In all, 149 cases from 28 medical clinics were analyzed. Six subjects were required recollection of samples because of a low fetal DNA fraction in the initially obtained samples. Of these 6 subjects, no sample could be collected from one. Of the remaining 148 cases, 144 had a low risk of trisomy, and 4 had a high risk for Down syndrome, thus providing a positivity percentage of 2.7%. Fetal DNA fraction in the maternal blood samples ranged from 4.2% to 23.7% with a mean value of 12.0%. We have experienced cases with a high risk for Down syndrome with genomics-based NIPT referred to abroad.

Researchers have an ethical responsibility to report the results of research involving human subjects. Dissemination of results ensures that patient care is based on good science and that the field of medicine advances based on complete and accurate knowledge. However, current evidence suggests that publication is often neglected or substantially delayed, especially in the case of negative and inconclusive results. Researchers, editors and reviewers should value all high-quality research regardless of the conclusiveness of the results and ensure that all research involving human subjects is registered in a publicly accessible database.
