Adenomatoid tumor of the uterus is a rare benign neoplasm which has been known as mesothelial origin. Characteristically, it appears as a small nodular lesion less than 2.0cm in the myometrium of subserosal region. We describe a case of giant adenomatoid tumor of the uterus having multicystic gross appearance. A 49-year-old woman complained of vaginal bleeding. The tumor was an intramural mass with maximum diameter of 10 cm and located at posterior wall of the uterus. Histologically, the tumor was composed of multiple cystic cavities of variable size lined by flattened cells, lying among thin septa of connective tissue. Immunohistochemically, the cells are positive for low molecular weight cytokeratin(CAM 5.2) and are negative for factor VIII.

BACKGROUND: We performed electrical cardioversion for the patients with chormic nonvalvular atrial fibrillation under the transesophageal echocardiographic guidance after anticoagulation to evaluate the safety of this procedure and the effects of electrical cardioversion on the atrial function. METHODS: After anticoagulation therapy with coumadine for three weeks, we tried chemical cardioversion with amiodarone first. Failed cases were included in this study. Pre-cardioversion transesophageal echocardiographic parameters were measured after exclusion of thrombi. After sedation with intravenous midazolam, direct-current cardioversion was done with the transesophageal echocardiographic probe in situ. Immediately after sinus conversion, we measured echocardiographic parameters again. Spontaneous echo contrast(SEC), left atrial appendage flow velocity, pulmonary vein flow velocity and time-velocity-integral(TVI), transmitral flow velocity, TVI and deceleration time were measured. All patients were anticoagulated for at least 4 weeks after cardiovesion. RESULTS: The total number of patients was forty one(24 males, 17 females) with the mean age of 58 years(range : 39-70). Mean duration of atrial fibrillation was 65 months(range : 1-360). Hypertension(12), dilated cardiomyopathy(10), cerebrovascular accidents(6), ischemic heart disease(2) and chronic lung disease(1) were associated. There were no complications. SEC increased or newly appeared in 18(43.9%) patients after sinus conversion. The left atrial appendage emptying velocity decreased(32.8+/-17.4 vs. 22.1+/-11.4cm/sec, p=0.020) and systolic TVI of both upper pulmonic vein increased significantly after sinus conversion. In two cases, early systolic forward flow(S1) of pulmonic vein appeared after sinus conversion. Transmitral E velocity decreased(86.9+/-28.8 vs. 76.3+/-30.6cm/sec, p=0.006) and the deceleration time increased(164+/-49 vs. 206+/-53msec, p=0.000) after sinus conversion. Transmitral A velocity was still low(34.9+/-19.5cm/sec) and E/A ratio was high(2.6+/-1.4) immediately after sinus conversion. CONCLUSION: After appropriate anticoagulation therapy and exclusion of left atrium and left atrial appindage thrombi with TEE we could perform electrical cardioversion safety without complications. The changes in transesophageal echocardiographic parameters after sinus conversion revealed the appearance of atrial mechanical activity in concordance with electrical activity. But these findings suggested atrial stunning or electromechanical dissociation which necessitates extended anticoagulation therapy until the full recovery of atrial mechanical function.

Strumal carcinoid of the ovary is a rare turkor characterized by an intimate mixture of thyroid follicles and carcinoid. Herein is reported an ovarian strumal carcinoid in a serous cystadenoma from a 27-year-old pregnant woman. The thyroid follicular epithelial cells had immunohistochemically thyroglobulin and carcinoid tumor cells contained neuron-specific enolase, chromogranin and carcinoembryonic antigen. In addition, carcinoid cells showed neuroendocrine granules ultrastructurally. Calcitonin and amyloid were not found. This tumor may be originated from pluripotent endodermal germ cells on the basis of morphologic, immunohistochemical and ultrastructural studies.

Synovial sarcoma most commonly affects the extremities, especially the lower thigh and knee region. However, a smaller number develops in a central or axial distribution, an area which encompasses the trunk, orofacial, cervical and parapharyngeal regions. The retroperitoneum is an extremely unusual site and has never been recorded in the literature as primary a site for synovial sarcoma. We investigated a case of retroperitoneal synovial sarcoma in a 40-year-old woman. The specimen consisted of fragmented large bulky multinodular masses separated by slit-like spaces. The tumor was 130 gm in weight. Microscopically, the tumor was composed of nests of plump ovoid to polygonal shaped cells and bundles of spindle shaped cells, which had vesicular nuclei and a small amount of cytoplasm. In some areas, there were cleft like spaces and pseudoglandular structures lined by flat or cuboidal cells. Myxoid change, collagen deposition, foci of calcification and osseous metaplasia were also present. Immunohistochemically, the polygonal cells and some of the spindle cells reacted positively for keratin. The spindle cells, especially in the perivascular area were positive for vimentin. S-100 protein and GFAP were negative in both type of cells.

Carpal tunnel syndrome occurs infrequently in children. Genetic disorders and systemic disease of carpal tunnel syndrome may be the predisposing factors for carpal tunnel syndrome in children. Immunoglobulins (Ig) play a major role in adaptive immunity, and the loss of certain species of immunoglobulin is known to increase the risk of certain types of infection. Patients with hypogammaglobulinemia have an increased risk of cellulitis, arthritis and osteomyelitis. We describe the management of bilateral carpal tunnel syndrome in children with hypogammaglobulinemia.

In 1971, Harris introduced a metal backed acetabular cup to allow replacement of worn polyethylene cups and it has been popularly used now. In metal backed acetabular cup, dissociation between metal shell and polyethylene liner usually occurs with hip dislocation. We report a case of dissociation of polyethylene liner in metal bacded cup not associated with hip dislocation.

OBJECTIVE: The purpose of this study was to evaluate the survival rate of vitrified blastocyst according to the freezing vessels, equilibration time in cryoprotectant and artificial dehydration method. METHODS: Human blastocysts were vitrified after loading onto the plastic straw, open-pulled straw (OPS), electron microscopy grid (EM grid) for 1.5 min or 3 min. They also were directly plunged into LN2 within 30sec. For artificial shrinkage of blastocysts, 36 gauge fine needle was pushed at the cellular junction of the trophectoderm into the blstocoele cavity until it shrank without damage of inner cell mass. RESULTS: The survival rate of vitrified blastocysts on plastic straw, OPS, EM grid as freezing vessels were 26.7, 13.0 and 60.5%, respectively. The survival rate of EM grid was significantly higher than that of plastic straw and OPS (p<0.05). For 1.5 min equilibrium, the survival rates of early blastocyst (EB), middle blastocyst (MB) and late blastocyst (LB) were 64.4, 81.0, and 20.0% respectively. For 3 min equilibrium, the survival rates of EB, MB, and LB were 69.9, 50.0 and 57.5% respectively. The survival rates of EB and MB were significantly higher than that of LB in 1.5 min equilibrium group (p<0.05), however, the significance was not observed in 3 min equilibrium groups. In cytoplasmic shrinkage before vitrification, the survival rates of EB, MB and LB were 92.9, 100 and 75.9% respectively. The survival rate of MB was significantly higher than that of LB (p<0.05). The survival rates of vitrified blastocysts by artificial dehydration and slow-frozen blastocysts were not significantly different as 88.9 and 66.7%, respectively. CONCLUSION: This study showed that the vitrification of human blastocysts using EM grid and artificial dehydration is an effective method. Therefore, these methods would be an useful techniques for blastocyst cryopreservation.

Rectus muscle union in sixth nerve paralysis not only straightens the eye, but is a safe, simple, and effective procedure. It improves the function in the field of gaze of the involved muscle, produces a good cosmetic result, often with fusion, and little or no vertical imbalance. We conducted a retrospective study of 6 cases to investigate the effectiveness of surgical procedures(Jensen procedure) in the treatment of lateral rectus muscle paralysis. Medial rectus muscle recession was also performed in three cases.
