PURPOSE: We evaluated the ability of endo-rectal coil MRI (ER-MRI) to predict the local pathological stage of prostate cancer prior to radical prostatectomy and compared the results with those of transrectal ultrasonography (TRUS). MATERIALS AND METHODS: ER-MRI using high field magnets (1.5 Tesla) were performed in 22 patients (mean age 62.8 years, range 51-73) with clinically localized prostate cancer before radical prostatectomy. Of the 22 patients, 17 patients were also assessed by TRUS. The results of the imaging techniques were compared with the post-operative histopathological findings. As one patient with pelvic lymph node metastasis, which was detected on frozen-section examination during surgery, was spared radical prostatectomy, the final evaluation included 21 patients. RESULTS: DSeven of the 21 patients (33%) were found to have extraprostatic extension (EPE), and 5 had seminal vesicle invasion (SVI). The sensitivity and specificity for diagnosing EPE using ER-MRI were 62.5% and 84.6%, respectively, and 16.7% and 100% with TRUS. The sensitivity and specificity for diagnosing SVI were 80.0% and 93.8%, respectively with ER-MRI, and 0% and 92.3% with TRUS. The accuracy of predicting SVI was 90.5% with ER-MRI compared to 70.6% with TRUS. CONCLUSIONS: ER-MRI was significantly better than TRUS for determining the local extent of prostatic cancer and for prediction of SVI in the preoperative staging of clinically localized prostate cancer.

BACKGROUND: Pneumococcus is the most common cause of acute otitis media, community acquired pneumonia and invasive bacterial diseases in children. Ninety serotypes have been identified, and the distribution differs according to geographic area and ages. The 7 valent pneumococcal protein conjugate vaccine is used widely. To evaluate the efficacy of the vaccine, it is essential to investigate the distribution of the pneumococcal serotypes. MATERIALS AND METHODS: The serotypes and antibiotic resistance of the pneumococcus isolated from 308 patients at Shinchon Severance hospital from September of 2001 to July of 2005 were analyzed. RESULTS: The pneumococcci were isolated mostly from sputum and blood, and ear discharge in the descending order. Serotyping was possible in 265 cases, and the distribution of serotypes were 19F (16.2%), 19A (12.8%), 23F (8.7%), 6B (7.9%), and 6A (7.2%). Fifty two cases were isolated from those patients less than 16 years of age and the distribution of serotypes was 19F, 19A, 23F, 14, 6B, 6A and 4. Resistance to penicillin was 64.6% in all cases and 67.3% in children. The more common serotype showed the higher rate of penicillin resistance. Multi-drug resistance was demonstrated in 64.7%. Forty three percent of the total identified serotypes were included in the 7 valent pneumococcal conjugate vaccine. And 61.5% of the serotypes identified in children were included in the vaccine. CONCLUSION: The 7 valent vaccine may be used effetively in Korea. But, further study is needed to address serotype switching after the use of the protein conjugated vaccine, which has been reported in other countries.

PURPOSE: We evaluared the risk factors, clinical characteristic, diagnosis and treatment of neonatal systemic fungal infection in 28 cases in order to find ways to prevent development of and to improve the prognosis of neonatal systemic fungal infection METHODS: From November 1994 to August 1996, 28 premature infants who were diagnosed as systemic fungal infection at Ilsin Christian Hospital NICU were analyzed retrospectively. RESULTS: 1) The mean gestational age was 30.7 weeks(27-35.5weeks) and the mean birth weight was 1528g(975-2980g). 2) The risk factors associated with the development of neonatal systemic fungal infection included long-term use of broad-spectrum antibiotics, prolonged hyperalimentation, prolonged use of aminophylline and steroid, and endotracheal intubation. 3) The most common presenting clinical manifestations were temperature instability, feeding intolerance, and apnea. 4) In laboratory studies, blood, urine, and CSF culture positivity was 92.8%, 92.8%, and 10.7%, respectively and renal and cranial sonogram were helpful to evaluate the renal and CNS involvement. 5) The principal treatment was intravenous amphotericin B administration for 4 weeks. The side effects, such as renal toxicity, hepatotoxicity, hypokalemia, and vomiting, developed but were reversible. 6) The mortality rate was 7.1%, and ventriculo-peritoneal shunts was performed in 3 cases who had fungal meningitis for the management of postmeningitic hydrocephalus. CONCLUSION: For was beformedin the diagnosis of neonatal systemic fungal infection is very difficult and the mortality is high, we recommend that antifungal therapy be initiated in clinically ill infants who are not responsive to antibiotic therapy and have negative culture findings and have some of the risk factors associated with systemic fungal infection.

PURPOSE: Primary pulmonary lymphoma(PPL) arising in the lung as the initial site is very rare. Authors experienced two cases of PPL and report the radiologic findings and clinical characteristics with a brief reviewof the literature. METHODS AND MATERIALS: Plain chest radiograph and enhanced axial CT scan of the chest were taken. We analyzed radiologic findings of the two cases and correlated with broncoscopic and pathologic findings. RESULTS: Plain chest radiograph showed a mass like consolidative lesion on RML without peripheral atelectasis. Chest CT scan revealed a mass like consolidation with airbronchogram and the absence of a hilar mass or thoracic adenopathy. Percutaneous needle aspiration and biopsy(PCNA and PCNB) of the RML mass confirmed B-cell lymphoma, in both cases. CONCLUSION: PPL must be included in the differential diagnosis of chronic alveolar consolidation such as bronchioloalveolar cell carcinoma.

Desmoid tumors are defined as aggressive overgrowth of fibrous sheets and musculoaponeurotic structures. Although desmoid tumors are generally known as a benign neoplasm, it's aggresive local invasiveness and frequent recurrence indicate it's position lying between the benign and malignancy. The association of desmoid tumor and familial adenomtous polyposis(FAP) was first made in 1923 by Nichols. In 1951, Gardner reported the familial occurrence of intestinal polyposis, osteomas, fibromas, and epidermal or sebaceous cyst. Desmoid tumors are common in patients with FAP and Occur in 3.5~29% of patients with FAP whereas the incidence in the gerenal population is 2~5/1,000,000 person years. Surgical resection of desmoids in patients with FAP has been controversial because unresectability and recurrence are more common than cure. Palliative and curative resections have a high morbidity. Surgery should be reserved for those patients with symptomatic mesenteric desmoids. If a small mesenteric desmoid is encountered incidentally and is easily resectable, it should be resected. If surgery has been less than satisfactory in the treatment of these patients, several different medical approaches can be combined with or without surgical resection with mixed result. Authors report a case of unresectable mesenteric desmoid tumor, developing after surgery of FAP and literatures were reviewed

BACKGROUND: The etiology of Behçet's disease(BD) is not yet certain, and various hypotheses are suggested. In order to determine the role of dietary intake behavior in the pathogenesis of BD, we analyzed BD patients by questionnaire regarding their personal, social, and economic characteristics, and dietary intake behavior. METHODS: A series. of 79 patients who were registered at the Behçet's Disease Specialty Clinic at Severance Hospital, Yonsei University College of Medicine, Seoul, Korea were studied. The patients were classified and the data from the patients were analyzed according to the revised Japanese criteria. RESULTS: All patients except for suspected type patients took an average amount of nutrition close to the Korean Recommended Dietary Allowance(RDA). However, on the whole, the amount of consumption of Vitamin B2 and C was low and in the case of females, the consumption of Ca and Fe was makedly insufficient in accordance with the Korean RDA. In case of the level of dietary and serum zinc, there was no significant difference in patients or among groups. CONCLUSION: Since the consumption of some vitamins and minerals of patients were low, the behavior of dietary intake of BD patients which is considered to have a possible role in development of disease should be studied further.
