PURPOSE: We investigated if there are some differences in characteristic of recent renal infection from the past one and evaluated the need of ultrasonography in acute renal infection and the efficiency of antibiotics that have been used primarily in treatment of past renal infection. MATERIALS AND METHODS: We reviewed charts of 232 patients with acute renal infection retrospectively, who took admission treatment from 1991 to 1995 at our hospital. The laboratory tests such as complete blood count, urinalysis and urine culture with sensitivity and radiologic evaluations such as abdominal ultrasonography, excretory urography or voiding cystourethrography were performed. RESULTS: The most common age groups were 3rd decade(26.7%) and 4th decade(24.1%). Female was predominant in all age groups(M:F=1:8.7) except 1st decade(M:F=1.6:1). Acute pyelonephritis was the most common disease (87.1%) and then followed by acute focal bacterial nephritis(8.2%), renal abscess(4.3%) and perirenal abscess(0.4%). Five cases(2.2%) were accompanied by vesicoureteral reflux. Abdominal ultrasonography was done in 90.5%, but 74.8% of them were completely normal and most of abnormal findings at abdominal ultrasonography were clinically insignificant. Result of ultrasonography did not affect the outcome of the disease or the treatment plan. The significant bacterial isolation(more than 10(5)CFU/ml) in urine culture was 46.6%. Among them, E. coli was the most common organism(92.6%) and others were Enterobacter, Klebsiella or Pseudomonas. Causative agents were resistant to some drugs such as ampicillin or bactrim which have been usually used for urinary tract infection. CONCLUSIONS: Routine ultrasonography in renal infections without urinary tract obstruction was not helpful in treatment plan or outcome of this disease and selection of antibiotics in treatment of recent renal infection should be changed from the past one.

Papillary adenoma of the lung is a very rare tumor in humans. Papillary adenoma is benign, and morphologically distinctive neoplasm.Since Fanton et al. firstly described a bronchial tumor showing Clara cell features,only a few cases having features of both Clara cells and type II pneumocytes have been reported.The immunohistochemical and ultrastructural findings hint at an origin from type II pneumocytes or Clara cells.Noguchi et al. demonstrated the presence of surfactant apoprotein in cytoplasm of tumor cells in a case of papillary adenoma indicating type II pneumocyte-like differenciation of the tumor cells. The tumor was encounted in a asymptomatic patient in a mass-survey chest X-ray examination. The chest X-ray films showed the tumor as well dermacated small lesion. We reports a case of papillary adenoma of the lung with pulmomary sequestration with review of articles.

Although pulmonary valvular stenosis with intact ventricular septum is a common congenital abnormality, critical pulmonary stenosis of its severe form in the neonate is rare and highly fatal. With the development of percutaneous balloon valvuloplasty, surgical treatment is even more rare. This report is on a 2 day old male neonate with a critical pulmonary stenosis with intact ventricular septum who suffered from severe cyanosis and hypoxemia. Oxygen was inhalated and Prostaglandin E1 was infused initially and then arterial PO2 was increased from 19 mmHg to 54 mmHg. Percutaneous balloon valvuloplasty was attemped; however, the guidewire could not pass through the stenotic pulmonary valve, and during the procedure right ventricular perforation was suspected due to the presence of dye in the pericardial space. Emergency transarterial pulmonary valvotomy was performed using normothermic cardiopulmonary bypass. Postoperatively, the patient was in fair condition in the ICU and presently is in good condition at 6 months postoperative follow up.

Objective: Several particular morphological factors that contribute to the hemodynamics of the anterior communicating artery (ACoA) have been documented, but no study has investigated the role of the degree of anterior cerebral artery (ACA) rotation on the presence of ACoA aneurysms (ACoAAs). Methods: A retrospective study of an institutional aneurysm database was performed; patients with ruptured or nonruptured ACoAAs were selected. Two sex- and age-matched control groups were identified: control Group A (nonaneurysms) and control Group B (middle cerebral artery aneurysms). Measurements of ACA rotation degree were obtained by using a three-dimensional imaging tool. Results: From 2015 to 2020, 315 patients were identified: 105 in the ACoAA group, 105 in control Group A, and 105 in control Group B. The average age at the time of presentation was 64 years, and 52.4% were female. The ACA rotation degree of the ACoAA group was significantly higher than that of control Group A (p <0.01). The A1 ratio and the A1A2 ratio of the ACoAA group were greater than those of control Group A (p <0.01 and p <0.01, respectively). The ACA rotation degree correlated insignificantly with aneurysm size in ACoAA patients (p=0.78). The ACA rotation degree in the ACoAA group was also insignificantly different from that in control B (p=0.11). Conclusions The degree of ACA rotation was greater in the ACoAA group than in the nonaneurysm group, and it may serve as an imaging marker for ACoAA.

We carried out coronary artery bypass grafting using saphenous vein on 8 patients from May, 1987 through January, 1988 at Hanyang University Hospital in Seoul. There were 4 men and 4 women and the mean age was 58.3 years. Except for 1 patient, they were all diagnosed as unstable angina not responding to medical therapy. The average ejection fraction was 66.9%, and no operative death was found. Two sequential anastomoses were performed in one patient. There was no significant event to influence adversely on postoperative prognosis. During the mean follow up period of 6.3 months, none of the patients experienced new symptoms and all of them remain relatively well off the medications used pre and perioperatively execpt for aspirin and persantin.

Objective: The real-world INFORM study analyzed sociodemographics, treatment patterns and clinical outcomes for patients with newly diagnosed advanced epithelial ovarian cancer (EOC) in Australia, South Korea (S.Korea) and Taiwan preceding incorporation of poly(ADP-ribose) polymerase inhibitors into clinical practice. Methods: Retrospective data from patients diagnosed with EOC (high-grade serous EOC for Taiwan) between January 2014 and December 2018 with ≥12 months follow-up from diagnosis were analyzed descriptively. Survival was evaluated by Kaplan-Meier with two-sided 95% confidence interval (CI). Results: Of the 987 patients (Australia, 223; S.Korea, 513; Taiwan, 251), 98% received platinum-based chemotherapy (CT). In S.Korea and Taiwan 76.0% and 78.9% respectively underwent primary cytoreductive surgery; in Australia, 56.5% had interval debulking surgery. Bevacizumab was included in primary/maintenance therapy for 22.4%, 14.6% and 6.8% of patients in Australia, S.Korea and Taiwan, respectively. Patients receiving bevacizumab were high-risk (reimbursement policy) and achieved similar real-world progression-free survival (PFS) compared with CT only. Overall, the median real-world PFS (months; 95% CI) was similar across Australia (16.0 [14.63–18.08]), S.Korea (17.7 [16.18–19.27]) and Taiwan (19.1 [17.56–22.29]). Conclusion This study reveals poor prognosis despite differences in demographics and treatment patterns for patients with EOC across Asia-Pacific suggesting the need for biomarker-driven novel therapies to improve outcomes.
