High output heart failure due to congenital arteriovenous fistula is a rare disease and is difficult to treat. A 27 year old man, suffering from dyspnea, palpitation, lower extremity edema, and abdominal distension admitted May, 1987. At admission there were continuous thrill and bruit at left supraclavicular and infraclavicular area. The heart sound was irregular and rapid, and grade IV/VI pansystolic murmur was audible at the apex. Chest PA showed marked cardiomegaly with pleural effusion and notching at superior aspect of left 2nd rib. Selective left subclavian artery angiogram showed extensive congenital arteriovenous fistula at the area of left subclavian artery and its branches. After setrial feeding artery embolization and palliative operation, the fistula size decreased much with clinical improvement.

Neonatal meningitis caused by the Group B beta-hemolytic streptococcus was first reported in 1958. In recent years this organism has assumed major importance in the etiology of neonatal infection. In Korea, this organism is likely to play an increasing role in neonatal infection. So this investigation was designed to report the 9 cases of Group Bbeta-hemolytic streptococcus infected neonates admitted to the NICU, department of Pediatrics, Hanil Hospital from January 1990 to June 1993. The results were as followings. 1) Onset of disease was between 12days and 32 days of age and male to female ratio is 1:2. 2) Two cases were delivered by c-section, seven cases were by NFSD and all of the infants had normal birth weight with full term at delivery. Maternal obstetric and neonatal complications were not detected in all cases. 3) The common presenting symptoms were fever in all cases, seizure in 6 cases, feeding difficulty, lethargy, vomiting, etc. 4) Group Bbeta-hemolytic streptococcus was isolated in CSF of all cases and in blood of 6 cases. 5) There were abnormal brain CT findings in 4 cases of group Bbeta-hemolytic streptococcal meningitis. 6) The sensitive antibiotics were Cefotaxime, Cefazoline, Erythromycin, Ampicillin, Chloramphenicol, Clindamyucin and Penicillin. 7) All cases were reconvered except one case that expired on the 1st day of admission and 6 cases were followed up for the period of 2months to 33months without neurologic sequelae, of which 1 case revealed decreased wave on Lt. hemisphere in ABR.

Helicobacter pylori (H. pylori) is an important risk factor for chronic gastritis, peptic ulcer, and gastric cancer. Proteinase-activated receptor 2 (PAR2), subgroup of G-protein coupled receptor family, is highly expressed in gastric cancer, and chronic expression of cyclooxygenase-2 (COX-2) plays an important role in H. pylori-associated gastric carcinogenesis and inflammation. We previously demonstrated that H. pylori induced the expression of PAR2 and COX-2 in gastric epithelial cells. Present study aims to investigate whether COX-2 expression induced by H. pylori in Korean isolates is mediated by PAR2 via activation of Gi protein and Src kinase in gastric epithelial AGS cells. Results showed that H. pylori-induced COX-2 expression was inhibited in the cells transfected with antisense oligonucleotide for PAR2 or treated with Gi protein blocker pertussis toxin, Src kinase inhibitor herbimycin A and soybean trypsin inbitor, indicating that COX-2 expression is mediated by PAR2 through activation of Gi protein and Src kinase in gastric epithelial cells infected with H. pylori in Korean isolates. Thus, targeting the activation of PAR2 may be beneficial for prevention or treatment of gastric inflammation and carcinogenesis associated with H. pylori infection.

PURPOSE: Goggles are frequently worn in the sport of swimming and are designed to form a seal around the periorbital tissue orbit. The resultant pressure on the eye may have the potential to affect intraocular pressure and blood flow of the optic nerve head. This study evaluates the influence of wearing swimming goggles on intraocular pressure (IOP) and blood flow of the ocular nerve head (ONH) in normal subjects. MATERIALS AND METHODS: Thirty healthy participants took part in this study. The IOP of each participant was measured using a Goldmann tonometer. Measurements were taken immediately before putting on swimming goggles, at 5, 10, 30, and 60 minutes after putting on swimming goggles, and then immediately after taking off the goggles. Blood flow of the ONH was measured using the Heidelberg retinal flowmeter. RESULTS: The average IOP before, during and after wearing the swimming goggles were 11.88 +/- 2.82mmHg, 14.20 +/- 2.81 mmHg and 11.78 +/- 2.89mmHg, respectively. The IOP increased immediately after putting on the goggles (p < 0.05) and then returned to normal values immediately after removal (p > 0.05). Blood flow of the ONH was 336.60 +/- 89.07 Arbitrary Units (AU) before and 319.18 +/- 96.02 AU after the goggles were worn (p < 0.05). CONCLUSION: A small but significant IOP elevation was observed immediately after the swimming goggles were put on. This elevated IOP was maintained while the goggles were kept on, and then returned to normal levels as soon as they were taken off. Blood flow of the ONH did not change significantly throughout the experiment. These facts should be considered for safety concerns, especially in advanced glaucoma patients.

A Clinical observation was made on five patients with ruptured aortic sinus of Valsalva who visited Seoul National university hospital during the period of May, 1975~Jan., 1980. 1. Age distribution was from 19 to 32 years and four patients were male and the rest one case was female. 2. Chief complaints on admission were dyspnea in 3 cases and chest pain in 2 cases. Onset of symptoms was abrupt in 4 cases. 3. Continuous murmur was heard at third and fourth intercostal space along left sternal border with thrill in all cases. 4. Cardiac catheterization and aortography showed regurgitant flow from aorta to right ventricle in all cases. 5. Operation was done successfully in 3 cases, of which aortic insufficiency was persistent in one case.

PURPOSE: We assessed the usefulness of magnetic resonance angiography(MRA) and its techniques for differential diagnosis of hemorrhagic causes in patients with non-traumatic intracranial hemorrhagic disease. MATERIALS AND METHODS: We retrospectively reviewed 74 patients with non-traumatic intracranial hemorrhagic diseases, which were confirmed by radiological examinations(36 cases) and operations(38 cases). We compared the usefulness of magnetic resonance imaging(MRI) alone from MRI with MRA in evaluation of hemorrhagic causes. MRA was obtained by Time-of-Flight(TOF) and Phase Contrast(PC) technique. We investigated the usefulness of TOF and PC technique. RESULTS: MRI with MRA for detection of hemorrhagic causes(89%, 66 cases) was better than MRI only (64%, 47 cases). PC was better than TOF for evaluation of arteriovenous malformation and aneurysm due to subtraction of background noise(hemorrhage). CONCLUSION: MRI with MRA in more useful than MRI alone for evaluation of non-traumatic intracranial hemorrhagic causes.
