We present a case of multiple cutaneous leiomyoma in a 45 year old woman. About 20 years ago, multiple skin colored papules developed on right cheek and man4ibular area. About 10 years after the onset of the disease a uterine myoma developed which wae tree,ted by total hysterectomy. The skin lesions were gradually increasing in number and size, Some larger nodular lesions changed to brown in color and became painful after cold exposure. The histopathologic finding showed typical leiomyoma arieing from arrector pilorum muscle.

Retroperitoneal foregut duplication cyst is an extremely rare congenital malformation. Pathologically, this lesion contains both gastric mucosa and respiratory type mucosa; radiologically, it is often challenging to differentiate it from the other cystic neoplasms that present a similar appearance. We report here on a case of retroperitoneal foregut duplication cyst that was lined by both gastric and pseudostratified ciliated columnar epithelium, and it was also accompanied by a pancreatic pseudocyst. Initially, it presented with peripancreatic and intrapancreatic cystic masses in an asymptomatic 30-year-old man, and this man has since undergone surgical resection.

BACKGROUND: In the management of liver transplantation, massive blood loss, interruption of venous retum to the heart, sudden infusion of acidic, cold and hyperkalemic blood from the graft, and uses of inotropic and vasoactive agents make cardiac output (CO) change unpredictably. We tried to find convenient method to estimate the change of CO by mixed venous oxygen saturation (SvO2) which can be monitored by pulmonary artery catheterization with fiberoptic oximeter using a spectrophotometer, By adapting the equation of oxygen transport and oxygen consumption(VO2), the equation CO=V/O2(Hbx0.134)x1/(SaO2-SvO2) can be obtained. If we assume the VO2 and hemoglobin concentration is constant and hypoxemia is excluded, CO might be proportional to I/(100-Sv O2). METHOD: For the management of orthotopic liver transplantations in 5 mongrel dogs, we continuously monitored Sv O2 with fiberoptic pulmonary catheter and intermittently measured the CO by thermodilution method according to operative phases. The Pearsons correlation coefficients between CO and mean arterial pressure, CO and S vO. and CO and 1/(100 SvO2) were measured in each dog. RESULT: The correlation coefficients between CO and 1/(100 SvO2) are raging from 0.74 to 0.98 with a corrected mean of 0.847 and significant in all dogs (p<0.05), and the correlation coefficients between CO and SvO2 are ranging from 0.67 to 0.96 with a corrected means of 0.786 and significant in 4 of 5 dogs. CONCLUSIONS: For the management of liver transplantation, the continuous monitoring of mixed venous oxygen saturation by a fiberoptic pulmonary catheter is helpful to detect changes of cardiac output.

Gastric volvulus can either present as an acute or chronic symptoms according to the degree of gastric rotation and subsequent obstruction. The diagnosis of gastric volvulus is often difficult and is mainly based on imaging studies. We describe a case of mesenteroaxial gastric volvulus associated with paraesophageal hernia, well demonstrated on upper gastrointestinal (UGI) series and coronal reconstructed CT image.

OBJECTIVES: Recently, it was suggested that apoptosis may be a basic mechanism of follicular atretic process. If the POF(premature ovarian failure) results from an acceleration of the process of atresia of the oocytes causing premature deletion of stored oocytes, POF may be a good model for the apoptosis. Our objective is to determine the relation between the POF and apoptosis. METHODS: We performed laparoscopic ovarian biopsy in 17 patients with POF. We evaluated the ovaries from a patient with POF by conventional H-E stining and immunohistochemical staining for apoptosis related protein(bcl-2, bax, fas and fas-L). RESULTS: Atretic cystic follicles were seen 4 out of 17 patients, and corpora albicans indicating past ovulation were seen 9 out of 17 patients. Primordial follicles were seen in 3 out of 17 patients, however developing follicles were not seen in all patients. Immunohistochemical analysis revealed that Bax was expressed in the lining cells of the atretic cystic follicle and primordial follicle and mesothelial cells lining the surface of the ovary. Fas and Fas-L were expressed on the lining pregranulosa cells and primary oocyte of the primordial follicle in the ovary of the patient with premature ovarian failure. Bax were also expressed on the lining pregranulosa cell and oocyte of the premature ovarian failure. Bcl-2 was expressed in the lining cells of primordial follicles of the patients with POF. CONCLUSION: Apoptosis may be a basic mechanism of POF. Bax, fas and fas-L may play a role causing premature follicular depletion.

PURPOSE: Intrahepatic duct stone (IHD) disease, especially bilateral lesion, is difficult to management for complete cure. The purpose of this study is to analyze the clinical manifestations and treatment outcomes and is to consider adequate strategy of treatment between unilateral and bilateral IHD stones. METHODS: From October 1993 to July 2004, 218 patients with IHD stone were performed by surgical management at Ewha Womans University Mokdong Hospital. The medical records of these patients were reviewed retrospectively. We classified into two groups, such as unilateral group (U group) and bilateral group (B group), and compared two groups for clinical manifestations and outcomes. RESULTS: Of the 218 IHD stone patients, 188 cases underwent conventional open surgery, 20 cases underwent laparoscopic surgery, and 10 cases underwent laparoscopic assisted surgery. U group and B group was composed 162 and 56 cases, respectively. IHD stones were more common in left lobe of liver than right lobe in U group (P<0.001). IHD stricture were more common in U group (P=0.048). On the other hand, remnant stones were more common in B group (P<0.001). There was no statistical significance for postoperative complication and method of operation include liver resection between two groups. CONCLUSION: We presume that the pathogenesis may be different between unilateral and bilateral IHD stone. To cure or reduce the remnant stone rate, more aggressive treatment such as liver resection should be also considered in the patients with bilateral as well as unilateral IHD stone because of no difference of complication rate of two groups.
