From November 1987 to December 1995, 76 patients with periampullary cancer underwent resectional surgery in the department of surgery, Kosin medical college. The object of this study was to assess the prognostic factors of the periampullary cancer after pancreaticoduodenectomy. The postoperative mortality rate was 11.8%. Significant morbidity occurred in 39.5% of the patients, early reoperation was required in 9.2% of these patients, and the mean hospital stay was 21.7 days. Univariate analysis on all patients revealed that the survival rate was significantly related to the size of the tumor (> or =3.0 cm 13%, <3.0 cm 41.4%; p<0.05), lymph node status (invasion 8.7%, no invasion 31.8%; p<0.05) and the age of the patient (>50 20.5%, < or =50 34.5%; p<0.05). The site was less significant(distal CBD 27%, ampulla of Vater 16.7%, pancreas 9%, duodenum 2%; p>0.05). These results indicated that patients with a tumor size lesser than 3cm, without lymph node involvement, and under the age of 50 had a long term survival rate.

The family Peronosporaceae, an obligate biotrophic group of Oomycota, causes downy mildew disease on many cultivated and ornamental plants such as beet, cucumber, grape, onion, rose, spinach, and sunflower. To investigate the diversity of Peronosporaceae species in Korea, we performed morphological analysis for dried plant herbariums with downy mildew infections by two largest genera, Peronospora and Plasmopara. As a result, it was confirmed that there are five species of Peronospora and two species of Plasmopara, which have been so far unrecorded in Korea, as well as rarely known in the world; Pl. angustiterminalis (ex Xanthium strumarium), Pl. siegesbeckiae (ex Siegesbeckia glabrescens), P. chenopodii-ambrosioidis (ex Chenopodium ambrosioides), P. chenopodii-ficifolii (ex Chenopodium ficifolium), P. clinopodii (ex Clinopodium cf. vulgare), P. elsholtziae (ex Elsholtzia ciliata), and P. lathyrina (ex Lathyrus japonicus). In addition, their phylogenetic relationship was inferred by molecular sequence analysis of ITS, LSU rDNA, and cox2 mtDNA. By rediscovering the seven missing species and barcoding their DNA sequences, this study provides valuable insights into the diversity and evolutionary studies of downy mildew pathogens.

PURPOSE: Streptococcus pyogenes is an important cause of invasive diseases in children. We aimed to describe the clinical characteristics of invasive infections due to S. pyogenes in children in Korea. METHODS: A retrospective study of children under 18 years of age with invasive infections due to S. pyogenes at Seoul National University Children's Hospital between March 1992 and December 2012, and Seoul National University Bundang Hospital between March 2003 and December 2012 was conducted. Demographic factors, clinical characteristics, laboratory findings, treatment, mortality and morbidity of all patients were reviewed. RESULTS: A total of 30 among 36 cases identified as invasive disease due to S. pyogenes were available for review. There was a predominance for male subjects (male:female=2.75:1). The median age was 50 months (range 12 days to 15 years) and 53.3% were under 5 years of age. Skin and soft tissue infections (9/30, 30.0%), bacteremia without identified focus (4/30, 13.3%) and bone and joint infections (6/30, 20.0%) were the most frequent clinical presentations. Streptococcal toxic shock syndrome (3/30, 10.0%) pulmonary, abdomen and central nervous system infections (2/30, 6.7%) were also seen. There was a peak in number of patients in year 2012 (9/30, 30.0%). There were no cases of mortality. Erythromycin and clindamycin resistance rates were low by 3.8% and 7.5%, respectively. CONCLUSION: We studied the clinical presentations of invasive infections due to S. pyogenes during the past 20 years in Korean children. The findings of this study help us understand the characteristics of the disease, enhancing early recognition and prompting adequate antibiotic therapy which is important in reducing morbidity and mortality.

Exogenous lipoid pneumonia occurs rarely in healthy people. In most cases, exogenous lipoid pneumonia is usually caused by aspiration of mineral, vegetable, or animal oil. We report the case of 42-year-old woman, who have experienced lipoid pneumonia after silicon injection into her breast for cosmetic purposes. The patient experienced fever, dyspnea, sputum, and hemoptysis after silicon injection into her breast. Chest computed tomography demonstrated non-segmental distribution of bilateral consolidation in both lung fields. A transbronchial lung biopsy specimen shows foamy microphages in alveolar spaces. Papanicolaous staining of bronchoalveolar lavage fluid showed abundant foamy marcrophages and many neutrophils. With these results, we confirmed lipoid pneumonia was associated with silicon oil injection into breast.

Transurethral removal of bladder or urethral stones in children is not easy and open removal of the stone is required in many cases because the urethra in a child is narrow and adequate equipment is not available. In a 6-year old boy with multiple urinary stones who had underwent vesicolithotomy twice before, we tried percutaneous removal of the bladder stones using suprapubic trocar and adult cystourethroscope set. Nelaton catheter was used as a guide wire in Seldinger technique while switching the instruments through the suprapubic cystostomy tract. With the same technique we removed a urethral stone in a 5-year boy successfully."

Tuberculous meningitis is qutie a common disease and delay in treatment is associated with poor prognosis. But the study on the prognosis of tuberculous meningitis is rare in Korea. We analyzed the clinical and laboratory findings of 159 cases seen between 1986 and 1990 at the Yonsei University College of Medicine, Severance Hospital. The specific aims of this study were to evaluate the clinical presentation, course and outcome and to determine the factors that may have influence on the outcome of tuberculous meningitis. The following results were obtained. 1. The highest incidence of age was noted in third decade as 37 cases (23.3%)and there was a tendency that the annual incidence of tuberculous meningitis declined since 1989. 2. The most presenting symptoms on admission were headache in 114 cases (71.7%), fever and chilling in 112 cases (70.4%), nausea and vomiting in 71 cases (44.7%), altered consciousness in 38 cases(23.9%) in order and clinical stage on admission revealed 83 cases of stage 2 and 14 cases of stage 3. 3. Associated tuberculous lesions other than central nervous system were found in 56 cases (35.2%) including miliary tuberculosis (15.7%), pulmonary tuberculosis (13.8%), spinal tuberculosis (3.1%), renal tuberculosis and so on. 4. Comparing with those who have not developed neurological sequelae on discharge, the mean protein value of cerebrospinal fluid on admission was increased and the mean glucose value and WBC count were decreased in patients who have developed neurological sequelae. 5. Brain computed tomography scan was performed in 122 cases and it revealed no abnormal findings in 54 cases (44.3%), enlarged ventricle in 44 cases (36.1%), basal enhancement in 25 cases (20.5%), lacunes in 18 cases (14.8%) and tuberculous granu-lomas in 8 cases (6.6%). 6. The neurological sequelae were developed in 53 cases (33.3%) including altered consciousness (13.2%), cranial nerve palsies (10.1%), death (5.0%), hemiparesis (4.4%), paraparesis(3.1%)and so on. 7.
