Acute human immunodeficiency virus (HIV) infection is a transient symptomatic illness associated with high-titer HIV replication and an expansive immunologic response to the invading pathogen. The diagnosis of acute HIV infection is difficult because the symptoms are those of common illnesses and HIV antibodies are usually not detected during the early phase of infection. An accurate early diagnosis is important because of the potential clinical benefit of early antiretroviral therapy, and to prevent the spread of infection. We report a case of acute HIV infection presenting as an acute febrile illness. We started treatment with highly active antiretroviral therapy (HAART) and the patient is now well with no other complications

BACKGROUND: Tight control of blood pressure in patients with coronary artery disease is critical, especially in the setting of long-standing hypertension and left ventricular dysfunction. With off-pump coronary artery bypass graft (CABG), hypertension usually occurs after the sternotomy, along with an increase in heart rate and filling pressure. In order to minimize hypertension during this period, nitroglycerin or nicardipine was prophylactically infused. METHODS: Twenty patients scheduled to undergo an off-pump CABG from April to August, 2001, were selected and divided into two groups. Group I (n = 10) received nicardipine and Group II (n = 10) received nitroglycerin. Before the skin incision, nicardipine (0.5 - 1.0ng/kg/min) or nitroglycerin (0.5 - 1.0ng/kg/min) was continuously infused. Mean arterial pressure (MAP), heart rate (HR), mean pulmonary artery pressure (mPAP), pulmonary artery occlusion pressure (PAOP), cardiac index (CI), and the systemic vascular resistance index (SVRI) were repeatedly measured at the stages of preincision, postincision, poststernotomy, pericardium open, and 10 min after reperfusion. RESULTS: Although MAP after the sternotomy was increased compared with preincision, it remained within a normal range. Similarly, HR, mPAP, and PAOP were all within a normal range despite increases. The CI was within a normal range at all stages in both groups, and there were no significant difference between the two groups. In group I, the SVRI was significantly decreased compared with group II when pericardium was opened. CONCLUSIONS: Both nicardipine and nitroglycerin were effective in preventing or attenuating hypertension after sternotomy with the hemodynamic stability.

PURPOSE: Minimally invasive surgery (MIS) in abdomen and thorax has been widely accepted for pediatric diseases. Thoracoscopic surgery has the advantage of less pain, better cosmetic outcomes and less musculoskeletal sequelae in comparison to open surgery. We would like to share our initial experience with thoracoscopic surgery performed by one pediatric surgeon. METHODS: We performed a retrospective review of patients who underwent thoracoscopic surgery by one pediatric surgeon between April 2010 and August 2017 in Department of Pediatric Surgery, Seoul National University Children's Hospital. RESULTS: There were totally 18 cases; 8 cases for esophageal atresia, 3 cases for congenital diaphragm hernia, 2 cases for diaphragm eventration, 2 cases for esophageal duplication cyst, 2 cases for pleural mass and 1 case for esophageal bronchus. At the operation, median age was 9.5 months (range, 0-259 months) and median body weight was 9.4 kg (range, 1.9-49.4 kg). Median operative time was 157.5 minutes (range, 45-335 minutes). There was no case of open conversion and 2 cases of minor leakage at anastomosis site in case of esophageal atresia. Median follow-up month was 5 months (range, 0-87 months). During follow-up, 4 cases of esophageal atresia showed anastomosis site narrowing and average 2.5 times (range, 1-5 times) of esophageal balloon dilatation was done. CONCLUSION: We performed thoracoscopic surgery in case of esophageal, diaphragm disease and pleural mass. Thoracoscopic surgery can be an effective and feasible option of treatment for well-selected pediatric patients of intra-thoracic disease including esophagus, diaphragm and mediastinum disease.

Bleeding frorn the duodenal varix is an unusual event. Upper gastrointestinal endoscopy is the diagnostic procedure of choice in diagnosing duodenal varices. If performed during active bleeding, it can differentiate between esophageal and duodenal varices as the source, which has important therapeutic implications. A thorough examination of the duodenum for varices is important in an upper gastrointestinal hemorrhage. Treatment modalites for bleeding duodenal varices are sclerotherapy, varix suture ligation, portocaval shunt, and duodenal resection. Although endoscopic sclerotherapy has lirnited success in controlling active duodenal varix as initial treatment, endoscopic injection sclerotherapy is a useful first-line therapeutic measure in the treatment of bleeding duodenal varices. In this study we present a case of a ruptured duodenal varix, which was defected by an endoscopy, in a 61-year-old male. An endoscopic examination showed small and nonbleeding esophageal varices and a prominant ulcerated varix was identified in the 2nd portion of the duodenum. Endoscopic sclerotherapy was performed by injecting ethanolamine oleate into the varix. Our report demonstrate that endoscopic sclerotherapy can be efficient even in the presence of acute bleeding and that it can provide a definitive method of curing of a bleeding duodenal varix.

Purpose: The oncoplastic breast-conserving surgery (OPS) technique, combined with the principles of oncological safety and plastic surgery, results in complete tumor resection while preserving the natural appearance of the breast. The purpose of this study was to evaluate the long-term oncological results after OPS compared with conventional breast-conserving surgery (BCS) for early breast cancer. Methods: The medical records of patients who underwent breast cancer surgery and adjuvant radiation therapy at Seoul National University Hospital between 2011 and 2014 were reviewed. Ipsilateral breast tumor recurrence (IBTR)-free survival rate and recurrence-free survival (RFS) rates were compared between the OPS and BCS groups. Results: One-to-one propensity score matching was conducted, yielding 371 patients in each group. The mean tumor distance from the nipple was shorter, and the mean retrieved specimen size and pathologic tumor size, including ductal carcinoma in situ, were larger in the OPS group than in the conventional BCS group (p < 0.001). Surgical margin positivity was not significantly different between the two groups (p = 0.777). The surgical technique was not significantly associated with IBTR (OPS versus conventional BCS, 5-year survival rate, 96.9% vs. 98.6%; p = 0.355) and RFS (5-year survival rate, 92.9% vs. 94.5%; p = 0.357) on the log-rank test. Multivariate analysis revealed that OPS versus conventional BCS was not significantly associated with survival outcomes. Conclusion We observed no significant differences in long-term IBTR and RFS between the OPS and conventional BCS groups in this retrospective analysis. OPS can be an oncologically and surgically safe alternative option for conventional BCS for early breast cancer.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is the most common organism associated with nosocomial infections. MRSA infections are becoming increasing important because they have emerged no only as healthcare-associated (HA) infections but also as community-associated (CA) ones. This study examined the moleculo-epidemiology of MRSA, which was isolated from nasal swabs in the intensive care unit (ICU) at Konyang University Hospital. MRSA are classified into HA-MRSA and CA-MRSA. METHODS: From June to September 2006, 353 patients who were admitted to the ICU in Konyang University Hospital were enrolled in this study. Single nasal swabs were obtained for culture in the ICU on the 1st day. Pulsed-field gel electrophoresis and the antimicrobial resistant patterns were analyzed between HA- and CA-MRSA. An antimicrobial sensitivity test was also performed. RESULTS: Forty two strains of MRSA were isolated from 353 patients (11.9%). Among the 42 isolates, HA-MRSA and CA-MRSA were found in 33 (78.6%), and 9 (21.4%), respectively. Eleven different PFGE types (type A to K) were identified. Types A (n=9) and B (n=7) were the most common for HA-MRSA, and types A (n=2) and B (n=2) were identified in CA-MRSA. The proportion of types A and B in CA-MRSA (44.4%) was similar to that in HA-MRSA (48.5%). The rates of resistance rates to erythromycin and ciprofloxacin were higher in HA-MRSA than in CA-MRSA. CONCLUSION: The rate of isolation of MRSA in an ICU setting was 11.9%. HA-MRSA was isolated more frequently than CA-MRSA. The rate of resistance of HA-MRSA to erythromycin and ciprofloxacin was higher than that of CA-MRSA. Despite the small number of subjects, the main isolates (type A and B) of CA-MRSA were similar to those of HA-MRSA.

OBJECTIVE: To describe the angiographic embolization as a safe and an effective alternative treatment in the management of obstetrical hemorrhage and in preserving fertility. METHODS: Between March 1999 and May 2003, 43 patients at Asan Medical Center underwent angiographic embolization for the management of obstetrical hemorrhage. All cases received arterial embolization because of obstetrical hemorrhage unresponsive to conservative management or prophylaxis for massive obstetrical hemorrhage. Medical records were reviewed and detailed to collect adequate clinical data such as clinical status, underlying conditions, amount of transfusion, embolization sites, materials of embolization, duration of the procedure, complications associated with embolization, hospital stay, and the success rate. Patients were contacted by telephone to obtain long-term outcome for menstruation, desire for conception, and subsequent pregnancies. RESULTS: We have experienced the clinical successful embolization in 37 (86.0%) of 43 patients of obstetrical hemorrhage resulting from various causes. The main cause of hemorrhage was atony of uterus (n=17), followed by abnormal placentation (n=6), genital tract laceration (n=5). The average amount of blood transfusion was 7.0 units (range; 0-36 units). The average length of the time for the procedure was 68.2 minutes (range; 30-150 minutes). The average duration of hospitalization was 6.4 days (range; 3-20 days). The main complication after embolization was numbness and pain on right lower extremities in 5 cases and vessel dissection occurred in 1 case. But there was no major complication related to the procedure. We were able to follow up 28 patients. In all cases menses resumed spontaneously soon after the procedure. Seven cases of long-term follow-up became pregnant, and 3 cases of them completed gestations giving birth to healthy babies. CONCLUSION: The results suggest that angiographic embolization is a relatively noninvasive and highly effective method for the management of obstetrical hemorrhage and a useful technique for preserving fertility.

To understand protozoan, viral, and bacterial infections in diarrheal patients, we analyzed positivity and mixed-infection status with 3 protozoans, 4 viruses, and 10 bacteria in hospitalized diarrheal patients during 2004-2006 in the Republic of Korea. A total of 76,652 stool samples were collected from 96 hospitals across the nation. The positivity for protozoa, viruses, and bacteria was 129, 1,759, and 1,797 per 10,000 persons, respectively. Especially, Cryptosporidium parvum was highly mixed-infected with rotavirus among pediatric diarrheal patients (29.5 per 100 C. parvum positive cases), and Entamoeba histolytica was mixed-infected with Clostridium perfringens (10.3 per 100 E. histolytica positive cases) in protozoan-diarrheal patients. Those infected with rotavirus and C. perfringens constituted relatively high proportions among mixed infection cases from January to April. The positivity for rotavirus among viral infection for those aged < or = 5 years was significantly higher, while C. perfringens among bacterial infection was higher for > or = 50 years. The information for association of viral and bacterial infections with enteropathogenic protozoa in diarrheal patients may contribute to improvement of care for diarrhea as well as development of control strategies for diarrheal diseases in Korea.
