The heterotopic and tissues may be divided into two categories: those that are found in the head and neck region, and those that arise elsewhere. The latter type is rare and most cases are found in the lungs of patients with neural tube defect, particularly anencephaly. Our report descrives anencephalic male infant with heterotopic glial nodules in both lungs. The largest nodule is 2x1.5x1 cm, locates in the lower lobe of the left lung, and has a round gray-white cut surface with cystic spaces. Microscopically, the nodules consist of irregularly arranged astrocytes and glial fibers, in which are embedded gland-like or cystically dilated bronchioles. The astrocytes and glial fibers are strongly positive for glial fibrillary acidic protein and show astrocytic filaments on electron microscopy. This will be an additional case supporting the amniotic fluid aspiration/implantation theory of pathogenetic mechanism of distal heerotopic glial tissue.

The incidence of endobronchial tumor in the pediatric period is very rare and the symptoms are very close to those of respiratory tract infection. Diagnosis can be delayed because of low clinical suspicion and the many ways in which these tumors can present. We report the first case, in Korea, of a pulmonary carcinoid tumor that presented with recurrent pneumonia at the same location in adolescence. Treatment is surgical and geared towards complete resection while sparing healthy lung parenchyma. Long-term and careful follow up is recommended to detect local and distant metastasis.

PURPOSE: To assess the nationwide rate of acute postoperative endophthalmitis (APE) after cataract extraction in Korea and to evaluate potential risk factors thereof. MATERIALS AND METHODS: Nationwide insurance claims data from July 2014 to June 2017 were reviewed. All patients with phacoemulsification or extracapsular/intracapsular cataract extraction were included. Exclusion criteria were combined glaucoma surgery or total vitrectomy or when the patient had a history of intraocular foreign body. RESULTS: In total, 1505103 cases (982203 patients) were included. APE developed in 953 cases (938 patients) with an overall incidence of 0.063%. After adjusting for possible confounding factors, male sex [odds ratio (OR) 1.42; 95% confidence interval (CI) 1.25–1.61; p<0.001], primary clinical setting, operations performed in non-major cities, usage of sutures (OR 2.82; 95% CI 2.13–3.74; p<0.001), anterior vitrectomy (OR 8.71; 95% CI 6.71–11.32; p<0.001), aphakic cataract surgery (OR 1.52; 95% CI 1.03–2.22; p=0.033), hypertension (OR 1.40; 95% CI 1.18–1.66; p<0.001), diabetes (OR 1.59; 95% CI 1.31–1.93; p<0.001), and chronic renal failure (OR 1.28; 95% CI 1.01–1.62; p=0.039) were found to be related to APE development. CONCLUSION: The incidence of APE after cataract extraction was consistent with reports from other studies. Additional research is needed to determine the relationship of newly found risk factors, such as hypertension, primary clinical setting, chronic renal failure, and usage of suturing, with APE development.

PURPOSE: Heptaplatin (SKI-2053 R) is a new platinum analogue, with a better toxicity profile than cisplatin, and has antitumor activity even in cisplatin resistant cell lines. 5-fluoruracil (5-FU) has shown synergy with platinum compounds. This phase II trial was designed to determine the efficacy and toxicities of heptaplatin/ 5-FU (5-fluorouracil) for treating stomach cancer. MATERIALS AND METHODS: Thirty-two patients with advanced, measurable gastric adenocarcinomas were enrolled in this trial. The treatment consisted of heptaplatin, 400 mg/m2/day (1 hour IV infusion), on day 1 and 5-FU, 800 mg/m2/day (12 hours IV infusion), on days 1 to 5. The cycles were repeated every 3 weeks. RESULTS: Of the 26 evaluable patients, 9 had partial responses and 1a complete response (overall response rate, 38%; 95% confidence interval, 19~57%). The median response duration was 23 weeks (range: 4~60 weeks). The median time to progression was 26 weeks (range: 3~68 weeks). The grades III-IV toxicities were mostly hematological toxicities: leucopenia was observed in 11 patients (35%) and thrombocytopenia 4 (13%). No definite neuropathy was observed. Grade I-II nephropathy was also noted: grade I high BUN/creatinine levels occurred in 5 patients (16%), grade II proteinuria 2 (6%), grade I proteinuria 5 (16%). Neutropenic fever developed in 5 patients (16%) and 1 died of pneumonia in a neutropenic state. CONCLUSION: This study suggests that the regimen of Heptaplatin/5-FU should be effective and have a favorable toxicity profile for the patients suffering with advanced stomach cancer.

BACKGROUND: In Korea, methicillin-resistant Staphylococcus aureus (MRSA) is the most common nosocomial pathogen, which is particularly prevalent in ICU. We performed this study to investigate the modes of transmission of MRSA and the role of nasal carriage of11RSA to subsequent MRSA infections in medical ICU. METHODS: All patients admitted to the medical lCU during 10 months were studied prospectively. Nasal swabs were done in all patients within 24 hours of admission and weekly thereafter. For patients who developed MRSA infections, additional cultures were done before start of antibiotics. Surveillance cultures of nostril, hands of health care workers and environment were done once at the end of the study. Bacterial typing was performed with pulsed-field gel electrophoresis (PFGE) using Smal. RESULTS: Among 138 patients enrolled, 24 patients (17.4 %) were nasal colonizers, and 9 patients (6.5%) were already infected with MRSA prior to admission. New nasal colonization among patients, in whom follow up nasal cultures were done at the interval of 3 days or more, developed at 36.2 % (21/58 patients). New infections of MRSA in patients who were admitted for more than 3 days, developed at 11.7 % (13/111 patients). Patients in isolation room were infected with MRSA less frequently (P <0.05). No other risk factors for nasal colonization of MRSA or MRSA infections were found. There were no significant differences between nasal colonizers and non-colonizers in the incidence of MRSA infections. PFGE analysis of MRSA isolates from patients showed several major patterns, which were similar in both MRSA isolates obtained prior to admission and those acquired after admission. PFGE patterns of MRSA isolates from health care workers and environment were different from those of patients. CONCLUSION: Patients who were infected or colonized with MRSA seemed to be a major source for transmission of MRSA in medical ICU. In medical lCU, where MRSA were prevalent, nasal colonization was not related to the increased incidence of MRSA infections.

BACKGROUND: The rate of pneumococcal resistance in Korea has surged up to the world's highest level in a short period. To investigate the genetic relatedness and the spread of resistant pneumococci within Korea, and to obtain the basic data about structural changes of penicillin-binding proteins(PBPs), we performed a fingerprinting analysis of PBP 1A, 2X, and 2B genes of multidrug-resistant pneumococci isolated in Korea. METHODS: A total of 22 pneumococcal strains isolated from clinical specimens in 2 university-affiliated hospitals during the period from 1989 to 1996 were tested. PBP 1A, 2X, and 2B genes were amplified from chromosomal DNA by the polymerase chain reaction with specific primers. Amplified products were digested with HinfI or MseI and DdeI and were followed by end-labeling with [alpha-32P] dCTP. Direct comparison of fingerprinting patterns between resistant strains and dendrogram analysis which was based on the UPGMA method were carried out. RESULTS: Fingerprinting analysis of PBP 1A, 2X, and 2B genes digested with HinfI showed that 17 out of 22 strains had almost identical patterns. Dendrogram showed that clusters with greater than 90% similarities existed in 77%, 77%, and 82% of strains with PBP 1A, PBP 2X, PBP 2B, respectively. Fingerprinting patterns with MseI and DdeI were the same as those with HinfI. CONCLUSION: Data from PCR fingerprinting analysis of PBP 1A, 2X, 2B genes of multidrug- resistant pneumococci in this study indicate the genetic relatedness between the resistant strains and suggest the possible spread of pneumococcal resistance within Korea.
