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

Fournier's gangrene is a form of necrotizing fasciitis of the perineal, genital or perianal region due to perianal infection, urinary tract infection or local trauma. Even though many patients may present with minor skin lesions in the early stages of the disease, the natural course of this necrotizing disease is rapid progression of gangrene, eventually resulting in sepsis and death. Therefore, rapid and accurate diagnosis is the most important factor for a successful outcome. We report two cases of Fournier's gangrene in a 21-year-old and 24-year-old male, both of whom commonly presented with painful swelling and tenderness of the scrotum. Although one man showed a rapidly-spreading erythema and induration to the flank and lateral chest, they were both successfully treated with early antibiotic therapy and surgical drainage.

PURPOSE: Three-dimensional radiation dosimetry using magnetic resonance imaging of polymer gel was recently introduced. This dosimetry system is based on radiation induced chain polymerization of acrylic monomers in a muscle equivalent gel and provide accurate 3 dimensional dose distribution. We planned this study to evaluate the clinical value of this 3-dimensional dosimetry. MATERIALS AND METHODS: The polymer gel poured into a cylindrical glass flask and a spherical glass flask. The cylindrical test tubes were for dose response evaluation and the spherical flasks, which is comparable to the human head, were for isodose curves. T2 maps from MR images were calculated using software, IDL. Dose distributions have been displayed for dosimetry. The same spherical flask of gel and the same irradiation technique was used for film and TLD dosimetry and compared with each other. RESULTS: The R2 of the gel respond linearly with radiation doses in the range of 2 to 15 Gy. The repeated dosimetry of spherical gel showed the same isodose curves. These isodose curves were identical to dose distributions from treatment planning system especially high dose range. In addition, the gel dosimetry system showed comparable or superior results with the film and TLD dosimetry. CONCLUSION: The 3-dimensional dosimetry for conformal radiation therapy using MRI of polymer gel showed stable and accurate results. Although more studies are needed for convenient clinical application, it appears to be a useful tool for conformal radiation therapy.

PURPOSE: Previously, Epstein-Barr virus (EBV) infection was diagnosed by serological examination; currently, many EBV antigen detection methods have been developed and applied clinically for diagnosing EBV infection. To delineate the clinical characteristics of EBV infection, clinical and laboratory findings were evaluated for patients who tested positive in EBV polymerase chain reaction (PCR). METHODS: EBV PCR was conducted in 352 patients admitted to the pediatric ward from January 2004 to December 2006, with more than 2 clinical signs such as fever (> or =37.5degrees C), exudative throat infection, lymphadenopathy, hepatitis of unknown etiology, and splenomegaly. The EBV viral gene was detected by PCR in 115 patients (32%), and the clinical characteristics of these patients were evaluated. Laboratory findings such as leukocytosis, thrombocytopenia, atypical lymphocyte, and alteration in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in peripheral blood were examined. The EBV-specific immunoglobulin M antibody (EBV-IgM Ab) was also tested. RESULTS: Most of the children were younger than 8 years (89%), and the male to female ratio was 1.3:1. Exudative throat infection and fever (> or =37.5degrees C) were observed in all patients. Cervical lymph node enlargement was seen in 36 patients (31%); leukocytosis (WBC> or =10,000/mm3), in 54 patients (47%); and atypical lymphocyte (> or =20%), in 28 patients (24%). EBV-IgM Ab was positive in 33 patients (29%). The younger patients had higher ALT levels and higher incidence of positive EBV-IgM Ab than the older patients. CONCLUSION: The cumulative number of patients diagnosed to have EBV infection by PCR increased markedly for those under 8 years. ALT was higher and EBV-IgM Ab was detected more in younger patients with EBV infection.

Inadvertent left internal mammary artery (LIMA)-great cardiac vein (GCV) anastomosis is a rare complication of coronary artery bypass graft surgery. Patients with iatrogenic aortocoronary fistula (ACF) were usually treated surgical repair, percutaneous embolic occlusion with coil or balloon. We report a case of iatrogenic LIMA to GCV anastomosis successfully treated with coil embolization and protected left main coronary intervention through the percutaneous transfemoral approach.

Left atrial wall calcification is frequently observed in patients with rheumatic valvular heart disease. However, massive left atrial wall calcification, so called porcelain or coconut atrium, with left atrium thrombi is very rare. Here, we describe the case of a 67-year-old male patient with porcelain atrium, recurrent left atrial thrombi, and a spontaneous axillary hematoma after mitral valve replacement and surgical thrombectomy due to rheumatic valvular heart disease. The patient underwent two valvular surgeries 20 years prior; therefore, we determined not to perform additional surgeries because of a high risk of morbidity, mortality, and the recurrence of atrial thrombi. The patient has been maintained on daily warfarin as an anti-thrombic therapy for more than 5 years without major embolic complications.

OBJECTIVE: To understand the physiologic effects and secretion pattern of inhibin A and inhibin B during menstrual cycle and menopausal transition, inhibin A and inhibin B levels were measured. And to detect any changes in expression of inhibins in human ovary with age, we examined immunohistochemical staining of alpha, beta A, and beta B subunits of inhibin in ovarian tissues. This study was also designed to investigate whether or not inhibin is an early marker for menopausal transition. METHODS: Inhibin A and inhibin B levels were measured in 320 samples from normal reproductive women, in 60 from perimenopausal women, and in 20 from menopausal women by ELISA. And we examined the immunohistochemical staining of alpha, beta A, and beta B subunits of inhibin in ovarian tissues of 35 normal reproductive, 20 perimenopausal, and 5 menopausal women, respectively. RESULTS: In the normal reproductive women, inhibin A begins to increase in the late proliferative phase (16.53 +/- 1.57 pg/ml), reaches the peak in the mid-secretory phase (45.85 +/- 2.08 pg/ml), and subsequently decreases. Inhibin B begins to increase in the early proliferative phase (65.40 +/- 4.08 pg/ml), reaches the peak in the ovulatory phase (110.74 +/- 9.83 pg/ml), and thereafter declines rapidly. In the perimenopausal women, mean inhibin A serum concentration was 6.68 +/- 0.53 pg/ml during proliferative phase and 21.78 +/- 3.61 pg/ml during secretory phase, which were significantly lower than that of the same phase in the normal reproductive women (P<0.01). Mean inhibin B serum concentration was 52.16 +/- 7.46 pg/ml during proliferative phase and 22.41 +/- 6.73 pg/ml during secretory phase, which were significantly lower than that of the same phase in the normal reproductive women (P<0.01, P=0.025). In the menopausal women, both inhibin A and inhibin B were not detected. In the normal reproductive women, we observed strong immunostaining for alpha subunit in granulosa cells, theca cells, and corpus luteum. Immunostaining for beta A subunit was observed in corpus luteum, but not in growing follicles. Immunostaining for beta B subunit was observed in primary follicle, granulosa and theca cells of growing follicle, and mature follicle, but less strong than immunostaining for alpha subunit. No staining for beta B subunit was observed in the corpus luteum. In the perimenopausal women, immunostaining for inhibin subunits were observed in the same pattern as that of the normal reproductive women, but weaker. Stronger immunostaining was observed in theca cells than in granulosa cells. In the menopausal women, none of the immunostaining of inhibin subunits were observed. CONCLUSION: It is concluded that inhibin A is associated with the luteal function and inhibin B, the follicular function. The secretion of inhibins decreased rapidly in the perimenopausal transition period and were not detected in the menopausal period. Inhibin A and inhibin B are associated with the follicular maturation and development. It suggests that the inhibin A and inhibin B are good candidates as markers for perimenopausal transition.
