Twin reversed arterial perfusion (TRAP) sequence is a rare specific anomaly of twin gestation with fused placenta and umbilical anastomosis. This syndrome occurs once in about 34,600 births and reported first by Beneditti in 1533. We report on prenatal diagnosis of a case of TRAP sequence with color Doppler sonography, this case is presented with a brief review of the literature.

PURPOSE: We compared prophylactic effects and complications of intravesical instillation of the Connaught and Tice strains bacillus Calmette-Guerin (BCG) in patients with stage pT1 bladder cancer. MATERIALS AND METHODS: A total of 98 patients with stage pT1 bladder cancer were treated with transurethral resection (TUR) between January 1992 and April 1998. Of the 98 patients, 51 received the Connaught strain BCG (81mg), 27 the Tice strain BCG (12.7mg) and 20 patients underwent TUR alone. The patients were followed-up for 18-78 months (mean 42.5months). The recurrence and progression rates, mean months to tumor recurrence, recurrence free survival rate, using Kaplan-Meier curve, and complications, were compared between the two BCG strain groups. RESULTS: The overall recurrence rate was 27.5% in the Connaught strain BCG group, 29.6% in Tice strain BCG group and 65% in TUR alone group. The mean months to tumor recurrence, and the recurrence free survival rate, showed that both BCG strain drugs were superior to TUR alone. Although the prophylactic efficacy of the Connaught strain BCG was a little higher than that of the Tice strain BCG, there were no significant differences in the recurrence rates and recurrence free survival rates between the two drugs. The incidences of complications were 94.1 and 85.2% in the Connaught strain BCG and Tice strain BCG groups, respectively. CONCLUSIONS: Both the Connaught and Tice BCG strains were superior to TUR alone in the prophylaxis of the recurrence in stage pT1 bladder cancer. There was no significant difference in the complication rates between the two groups. Therefore, both the Connaught and Tice BCG strains may be regarded as alternative treatments.

A 46-year-old female with abnormal radiologic finding was diagnosed with pancreatic neuroendocrine tumor and multiple hepatic metastasis. Molecular targeted therapy (everolimus) and two times of transarterial chemoembolizations (TACE) were performed before pylorus-preserving pancreaticoduodenectomy (PPPD). After 2nd TACE and PPPD, grade 2 pancreatic neuroendocrine tumor was pathologically confirmed. Four times of additional TACE was done. After size increase of several probable hepatic metastasis in the both lobes of liver, laparoscopic left lateral sectionectomy of liver was performed. After two and half years of left lateral sectionectomy, 7th TACE was performed and the patients have survived without further disease progression. This case suggests that patients with pancreatic neuroendocrine tumor and hepatic metastasis can be treated by TACE, primary tumor resection, surgery for liver metastasis and molecular targeted therapy. Therefore, aggressive multidisciplinary approaches need to be considered for long term survival of patients with pancreatic neuroendocrine tumor with hepatic metastasis.

Phenylpropanolamine is a sympathomimetic amine used widely as a decongestant or appetite suppressant. Reports of the myocardial injury from the use of phenylpropanolamine are rare and the mechanism of the myocardial injury is not known clearly. We experienced a case of myocardial injury after ingestion of phenyl-propanolamine. A 46-year-old woman was admitted because of chest pain and dyspnea after ingestion of 5 tablets of anorectic pill containing phenylpropanolamine 75 mg per tablet. The serum creatine kinase MB isoenzyme levels were elevated and electrocardiographic abnormalities suggesting myocardial infarction were seen in the precordial lead. In echocardiograpy, left ventricular anteroseptal wall motion was nearly akinetic but coronary angiography showed normal coronary arteries except sluggish blood flow in left anterior descending artery.

It is well known that newborns and pregnant women typically show higher rates of Streptococcus agalactiae infection. However, the incidence of group B streptococcal (GBS) disease in nonpregnant adults is increasing, particularly in elderly persons and those with significant underlying diseases, such as diabetes, neurologic impairment, and cirrhosis. Skin infections, osteoarticular infections, and pneumonia are commonly associated with GBS, while meningitis and endocarditis are less common. S. agalactiae endocarditis is an uncommon but important condition with a high mortality rate. Several cases of endocarditis due to S. agalactiae have been reported in the literature, but there have been no reports of S. agalactiae meningitis associated with endocarditis in Korea. Here, we describe a case of S. agalactiae meningitis and endocarditis in a 50-year-old man who was successfully treated with intravenous antibiotics and cardiac surgery.

Recent studies of molecular biology have suggested that infection with human papillomavirus(HPV) is implicated in the pathogenesis of cervical carinoma. HPV infection alone, however, does not appear to be sufficient for the process of maliganant transformation, suggesting the requirement of additional cellular events. The mutation of p53, which is involved in negative control of cell proliferation, may play a role in the carcinogenesis of cervical carcinoma. The present study was designed to clarify the association between infection with HPV and p53 alteration in primary carcinoma of human uterine cervix. We investigated 46 prim-ary cervical carcinomas for the presence of HPV DNA by in situ hybridization(ISH) with probe specific for HPV 16/18, and examined the accumulation of p53 protein by immunohis-tochemistry(IHC) and the p53 alteration by polymerase chain reaction-single strand confor-mation polymorphism(PCR-SSCP) using formalin fixed, paraffin -embedded tissue. HPV DNA 16/18 was detected in 18 cases(39.1%) of 46 cervical carcinomas. The accumulation of p53 was identified in tumor cells: low level 43.5%(20/46) and high level 32.6% difference of positive reaction by IHC method. But there was no statistical significant between the infection of HPV and the accumulation of p53(p=0.847). Mutations in exons 4 through 9, where the vast majority of point mutations were reported in human neoplasms, were screened by PCR-SSCP analysis. Altered mobilities of the PCR product of p53 were also found in 9 cases(26.5%) of 34 cervical carcinoma: one in exon 4, four in exon 5/6, two in exon 7, and two in exon 8/9. The mutation of p53 was observed in 41.1%(19/46) respective of the result of IHC and PCR-SSCP, and there was slightly higher p53 alteration in HPV negative cases(23.8%, 11/46) than in HPV positive cases(17.4%, 8/46) without statistical significance(p=0.729). The conclusion of these observations suggests that HPV infection and alteration of p53 may play a critical role in tumorigenesis of carcinoma of the human uterine cervix independently, ant there is important difference in the tumorigenic pathway between two factors.

BACKGROUND/AIMS: Western guidelines recommend Helicobacter pylori eradication in H. pylori-associated gastric polyps; however, there is no standard guideline in Korea. The aim of this study is to assess the effect of H. pylori eradication on the regression of gastric hyperplastic polyps in National Cancer Screening Cohort, representative of general population. METHODS: Among participants in National Cancer Screening Program, subjects who had H. pylori positive gastric hyperplastic polyps less than 10 mm and underwent follow-up endoscopy and H. pylori testing were enrolled. The effect of H. pylori eradication on hyperplastic gastric polyps was estimated using odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: A total of 183 H. pylori infected subjects with hyperplastic polyp at baseline underwent follow-up endoscopy and H. pylori test after mean of 2.2 years. Successful H. pylori eradication markedly induced the disappearance of hyperplastic polyps comparing to non-eradication group (83.7% vs. 34.1%, p = 0.001). Successful eradication increased the possibility of disappearance of hyperplastic polyps (adjusted OR, 5.56; 95% CI, 2.63 to 11.11). Polyp size was inversely related with the disappearance of hyperplastic polyps (adjusted OR, 59; 95% CI, 0.48 to 0.71). CONCLUSIONS: Eradication of H. pylori infection may induce disappearance of gastric hyperplastic polyps in National Cancer Screening Cohort.

Esophageal abscess caused by acute phlegmonous esophagitis is rare but life-threatening. Rapid abscess drainage is an important part of the treatment, and endoscope-assisted intra-luminal abscess drainage is frequently performed. Although endoscopic drainage is less invasive than surgery, it has the potential to cause esophageal stricture as a complication. We present a rare case of esophageal stricture as a complication of intra-luminal drainage and evaluate a method to minimize the incidence of esophageal stricture complications.

Background/Aims: Acute eosinophilic pneumonia (AEP) is common among military smokers; however, bronchoscopy is required for the diagnosis. We aimed to derive and validate a scoring system to diagnose AEP without bronchoscopy. Methods: We conducted a retrospective study including patients diagnosed with AEP or any other pneumonia among military smokers hospitalized in the Armed Forces Capital Hospital from 15 November 2016 through 25 December 2019. The patients were divided into derivation and validation groups according to their admission day. Patient symptoms, laboratory findings, and computed tomography findings were candidate variables. Least absolute shrinkage and selection operator (LASSO) regression was used to calculate the scores for each variable. Results: Among 414 patients, AEP was confirmed in 54 of 279 patients (19.4%) in the derivation group and in 18 of 135 patients (13.3%) in the validation group. Ten variables were selected using LASSO regression: new-onset or a recently increased smoking (≤ 4 weeks) (8 points), interlobular septal thickening (5 points), absence of sputum (3 points), ground glass opacity (3 points), acute onset (≤ 3 days) (2 points), dyspnea (2 points), chest pain (2 points), leukocytosis (2 points), bronchovascular bundle thickening (2 points), and bilateral involvement (2 points). The area under the receiver-operating characteristic curve of the score to diagnose AEP was 0.997 (95% confidence interval, 0.992 to 1.000) in the derivation group and 0.985 (95% confidence interval, 0.965 to 1.000) in the validation group. Conclusions We introduce a scoring system that can distinguish AEP from other types of pneumonia in military smokers without the need for bronchoscopy.
