Sex cord-stromal tumors of the ovary are the third most common types of neoplasms that develop in the ovary and account for about 5-8% of all ovarian malignancies. This group of ovarian neoplasms is derived from the sex cords and the ovarian stroma or mesenchyme. Granulosa-stromal cell tumors include granulosa cell tumor, thecoma and fibroma. The granulosa cell tumor is a low-grade malignancy and accounts for about 2-3% of all ovarian malignancies. Granulosa cell tumors have a prolonged natural history and tendency toward late relapse, reflecting their low grade biology. We present a case of juvenile granulosa cell tumor of the ovary with brief review of literature,

Solitary fibrous tumors (SFTs) are a rare spindle-cell neoplasm originating from mesenchymal fibroblast-like cells. Although they generally arise from submesothelial connective tissue in the pleura, many other locations have also been described, including the mediastinum, upper respiratory tract, orbit, salivary gland, thyroid, and prostate. SFT of the kidney, however, has rarely been described, and only 1 case has been reported in Korea. A 53-year-old female visited our hospital for abdominal pain, and abdominopelvic computed tomography showed a heterogeneous well-enhanced mass in the renal pelvis. She was treated with a laparoscopic radical nephroureterectomy, which revealed an SFT of the kidney.

Pasteurella multocida, a Gram-negative coccobacillus, is part of the normal oral flora of many types of animals, including domestic dogs and cats. It is the etiologic agent of a variety of infectious diseases, such as hemorrhagic septicemia in cattle or fowl cholera in chiken. Although this is a primary pathogen in the animal world, infection due to Pasteurella multocida in man has been described with increasing frequency recently. The majority of individuals with pasteurella multocida pulmonary infection possess some underlying pulmonary diseases, most commonly bronchiectasis or COPD. With review of literature, We report a young man who developed the empyema caused by Pasteurella multocida.

Nasal septal abscess can result from various causes such as septal hematoma from septal trauma or hematologic disorder, and infections of surrounding structures like nasal vestibule, upper lip and other oral lesions and hematogenous spread of other infections. Dentigerous cyst is one of the common odontogenic cysts, associated with unerupted teeth, and usually asymptomatic. Symptoms of the dentigerous cyst present mostly oral or maxillomadibular lesions, whereas nasal symptoms of the dentigerous cyst is uncommon. We report an unusual case of dentigerous of a 61 year-old of the dentigerous cyst of mesiodens with nasal septal abscess.

Plasma cholesterol is increased in normal aging in both rodents and humans. This is associated with reduced elimination of cholesterol and decreased receptor-mediated clearance of plasma low-density lipoprotein (LDL) cholesterol. The aims of this study were: (1) to determine age-related changes in plasma lipid profiles, and (2) to determine the effect of fenofibrate, an activator of peroxisome proliferator activated receptor alpha (PPAR alpha), on plasma lipid profiles in normal rats on a standard diet. Male Sprague-Dawley (SD) rats (n=15) were fed standard chow and water from 10 to 25 weeks of age. During that period, we measured daily food intake, body weight, fasting and random blood glucose levels, plasma total cholesterol (TC), triglycerides (TG), and free fatty acid (FFA) levels. At 20 weeks of age, all rats were randomly divided into two groups: a fenofibrate group (in which rats were gavaged with 300 mg/kg/day of fenofibrate) and a control group (gavaged with water). Fenofibrate treatment lasted 5 weeks. There were no significant changes in daily food intake, blood glucose, and plasma TG level with age. Body weight, plasma TC, and FFA levels were significantly increased with age. Fenofibrate significantly decreased plasma concentrations of TC and FFA, which had been increased with age. However, fenofibrate did not influence the plasma concentration of TG, which had not increased with age. These results suggest that fenofibrate might have a novel role in preventing age-related hypercholesterolemia in SD rats on a normal diet.

Primary malignant lymphoma of the breast is rare. The incidence of primary malignant lymphomas of the breast is 0.04% to 0.5% of all malignant tumors of the breast and 0.07% of all non-Hodgkin's lymphomas, and comprises 1.7% of extranodal malignant lymphomas that occur in Western countries. The incidence of mucosa- associated lymphoid tissue (MALT) lymphoma of the breast is reported to be between 0% and 75% of all primary malignant breast lymphomas in United States and Japan, but the incidence in Korea is unknown. MALT is characterized by indolent behavior and good has a prognosis. The authors report on a patient who has a primary MALT lymphoma of the breast. She was treated by surgical excision, which was followed by radiation therapy. Histologically, her lymphoma type transformed into a diffuse large B-cell tumor after 10months. She received combination chemotherapy and achieved a complete state of remission. She then underwent autologous peripheral blood stem cell transplantation along with high dose chemotherapy. To our knowledge, this is the first case report in the literature in Korea.

PURPOSE: The purpose of this study was to compare the effects of oral hygiene with 0.1% chlorhexidine or with normal saline on the incidence of pathogens in the oral cavity of patients in Intensive Care Units (ICU). METHOD: A quasi experimental design with non-equivalent control group and non-synchronized design was used. For the study 46 patients were recruited from a university hospital (24 for the experimental group, 22 for the control group). patients in the experimental group received mouth care with 0.1% chlorhexidine gluconate and those in the control group received mouth care with normal saline twice a day for 7 days in a row. Oral samples were taken for bacterial cultures on admission day, the 4th day and the 7th day for both groups. RESULTS: The incidence of oral pathogens decreased in the experimental group, and increased in the control group. There was no significant difference in the incidence of oral pathogens between the two groups. However oral hygiene using 0.1% chlorhexidine gluconate decreased the incidence of oral pathogens significantly for patients who already had pathogenic bacteria in their mouths on the admission day. CONCLUSION: The results suggest that mouth care with 0.1% chlorhexidine is effective for decreasing the incidence of oral infection for ICU patients who have oral infections.

BACKGROUND AND PURPOSE: Patients with mild cognitive impairment (MCI) and their caregivers are concerned with the likelihood and time course of progression to dementia. This study was performed to identify the clinical predictors of the MCI progression in a Korean registry, and investigated the effects of medications without evidence, frequently prescribed in clinical practice. METHODS: Using a Korean cohort that included older adults with MCI who completed at least one follow-up visit, clinical characteristics and total medical expenses including prescribed medications were compared between two groups: progressed to dementia or not. Cox proportional hazards regression analysis was conducted. RESULTS: During the mean 1.42±0.72 years, 215 (27.63%) of 778 participants progressed to dementia. The best predictors were age [hazard ratio (HR), 1.036; 95% confidence interval (CI), 1.006–1.067; p=0.018], apolipoprotein ε4 allele (HR, 2.247; 95% CI, 1.512–3.337; p<0.001), Clinical Dementia Rating scale-sum of boxes scores (HR, 1.367; 95% CI, 1.143–1.636; p=0.001), Instrumental Activities of Daily Living scores (HR, 1.035; 95% CI, 1.003–1.067; p=0.029), and lower Mini-Mental State Examination scores (HR, 0.892; 95% CI, 0.839–0.949; p<0.001). Total medical expenses were not different. CONCLUSIONS: Our data are in accordance with previous reports about clinical predictors for the progression from MCI to dementia. Total medical expenses were not different between groups with and without progression.

PURPOSE: The purpose of this study was to analyze the complications in renal transplant recipients and analyze the factors that affect the survival rate of transplant kidney and patients. METHODS: Between March 1985 and April 2000, 380 cases of renal transplantation were performed at Yeungnam University Hospital. The results were analyzed retrospectively. RESULTS: Infectious complications occurred 612 times in 215 cases and non-infectious complications occurred 200 times in 143 cases. The region of infection was in the order of urinary tract infection (461 times) and pulmonary infection (44 times). Non-infectious complications were as follows; hyperglycemia in 44 cases, de novo hypertension in 27 cases out of 35 previously normotensive patients, nephrotoxicity caused by CsA in 15 cases, myelosuppression in 14 cases, avascular necrosis in 10 cases, and malignancy in 9 cases. Surgical complications were as follows; renovascular bleeding in 15 cases, ureteral obstruction in 5 cases, lymphocele in 4 cases, ureteral leak in 3 cases, and intestinal obstruction in 3 cases. Out of total 380 cases of renal transplant, 113 times of acute rejection occurred in 99 cases. CONCLUSION: Infectious complications were most frequent complication. There were significant differences in graft survival for living non-related donor kidney transplantation by immunosuppressive regimen. CsA+PD+MMF group results in highest graft survival in living non-related donor kidney transplantation and was followed by CsA+PD group, CsA+PD+AZA group. But CsA+PD+MMF regimen has been used in recent years and it needs to be studied prospectively.

The limb-girdle muscular dystrophy type 2A (LGMD2A) is a recessively inherited disease caused by a mutation of the calpain 3 gene (CAPN3), and is considered one of the most prevalent subtypes of limb-girdle muscular dystrophy (LGMD). In this study, we aimed to identify CAPN3 mutations and to characterize the phenotype of Korean patients with LGMD2A. Among 35 patients with LGMD, four patients, who showed calpain 3 deficiency on western blot analysis, were analyzed in this study. Total RNA extracted from frozen muscle tissue was amplified by reverse transcriptase polymerase chain reaction (RT-PCR) using six primer pairs covering all coding sequences of CAPN3, and direct sequencing was performed. Clinical and pathological features of the patients were also reviewed. We found four different mutations in five alleles from three patients. Of the pathogenic mutations identified, two were novel (c.2125T>C and c.2355-2357delTTC), and the others had been reported elsewhere (c.440G>C, c.1076C>T). All patients showed a high CK level with predominant proximal leg weakness, and the onset was in their childhood except for one patient. Among two novel CAPN3 mutations, one was a missense mutation (c.2125T>C [p.709Ser>Pro]), and the other was a small in-frame deletion causing omission of a single amino acid (c.2355-2357delTTC [p.786delPhe]). The clinical features of our patients were generally compatible with the characteristics of LGMD2A patients described in the previous studies.
