OBJECTIVE: To compare the safety and efficacy of intravaginal misoprostol versus intracervical dinoprostone (prostaglandin E2 gel) for cervical ripening and labor induction. METHODS: 60 patients with indication for labor induction and unfavorable cervices were randomly assigned to receive either intravaginal misoprostol or intracervical dinoprostone. 50 microgram tablets of misoprostol were placed in the posterior vaginal fornix every 4 hours for a maximum of 3 doses or dinoprostone 0.5mg was placed into the endocervix every 6 hours for a maximum of 2doses. No more medication was given after either spontaneous rupture of membranes or beginning of active labor. RESULTS: Among 60 patients enrolled, 30 received misoprostol and 30 received dinoprostone. The average interval from start of induction to active labor was shorter in misoprostol group (6.5+/-3.2 hours) than in the dinoprostone group (10.7+/-7.3 hours) (p<0.05). Oxytocin augmentation of labor occurred more often in the dinoprostone group (36.7%) than in the misoprostol group (10.0%) (p<0.05). There was a higher prevalence of fetal distress (23.3% versus 3.3%) and tachysystole (16.6% versus 6.6%) in the misorprostol group than in the dinoprostone group(p<0.05). CONCLUSIONS: Vaginally administered misoprostol is an effective agent for cervical ripening and induction of labor. Furthermore, the cost of misoprostol ( 360/200microgram) is much less than that of dinoprostone ( 42,000/0.5mg). Cost benefits from administration of misoprostol are evident, especially in clinics under system of diagnosis-related group (DRG) : however when given at this dosage, it is associated with a higher prevalence of fetal distress and tachysystole than dinoprostone. Further studies to compare the safety of misoprostole to that of dinoprostone and to delineate an optimal dosing regimen for misoprostol are needed.

Epidermal cyst in the fibroadenoma of the breast is very rare. A 29-year-old woman presented with a lump in the upper outer quadrant of the right breast. Clinically it was a fibroadenoma and the excisional specimen showed an encapsulated, firm lobulated lesion with a cystic area on cut surface. The cystic area showed squamous metaplasia of the ductal epithelium and keratinous cyst formation in the fibroadenoma. We report this unusual case with review of literatures.

Development of antibody-based cancer therapies will be greatly facilitated if antibodies are better standardized in two fundamental issues that are specificity analysis of antibody reactivity and the detailed biodistribution and pharmacokinetic profile of antibodies. In the current endeavor we attempted to use an antibody binding specificity to target the tumor in a syngeneic carcinoembryonic antigen (CEA) tumor model. CEA, a 180 kDa glycoprotein, expressed at high levels on the surface of nearly all tumors of the gastrointestinal tract was used a potential target for antibody immunotherapy of gastrointestinal carcinomas. Using the CEA model antibody-based cancer therapy directed against CEA has been evaluated in a syngeneic animal model of disseminated disease. We constructed mouse/human chimeric anti-CEA IgG3, which has been evaluated for the specificity for CEA and the detailed biodistribution and pharmacokinetic profiles. Anti-CEA IgG3 heavy chain was expressed with the expected 180kDa molecular weight, assembled as H2L2 forms with a co-expressed mouse/human chimeric anti-CEA light chain, and were secreted. On FACS the purified anti-CEA IgG3 specifically recognized the mouse colon adenocarcinoma cell line MC-38 transduced with CEA (MCA32a), but not MC 38 without expressing CEA. After subcutaneous injection in C57BL/6 mice the half- lives of anti-CEA IgG3 and an irrelevant anti-dansyl IgG3 showed the bi-phasic kinetic patterns, and their pharmacokinetics of the distribution and the elimination were similar in mice. However, the biodistribution patterns of anti-CEA IgG3 were very different from those of anti-dansyl IgG3. Anti-dansyl IgG3 was mainly distributed into kidney until 72 hours, but anti-CEA IgG3 was slowly rernoved from blood and distributed into liver, kidney, spleen, and tumor. It is note worthy that anti- CEA IgG3 increased in targeting MCA32a tumor expressing human CEA by time, but the targeting to MC38 tumor was negligible. Thus, the increased targeting of anti- CEA IgG3 made MCA32a tumor grow slowly

Some sexual differentiation disorders are associated with gonadal neoplasia and increased incidence of testicular tumors has been discribed in the patients with, XY gonadal dysgenesis. The incidence of testicular tumors in infants and children are rare, representing only 1% of all pediatric solid tumors. In general, gonadal stromal tumors are one of the most characteristic endocrine tumors of the testis, endocrine activity occurs in at least 10-20%, among them Leydig cell tumors and Sertoli cell tumors are clinically important. Although the exact pathogenesis is unknown, endocrine activity due to estrogen secretion can be manifested clinically with gynecomastia or precocious puberty. We experienced and reported a child who visited for sexual precocity and had XY gonadal dysgenesis with Sertoli cell tumor.

We report a case of primary cutaneous mucinous adenocarcinotna in a 64-year-old female. The tumor was about 2cm in size, forminga round dome-shaped alopecic scalp mass which had gradually increased in size over about 5 years, Histalogic examination revealed that the tumor was divided into numerous compartments by strands of fibrous tissue. In each compartment, abundant amounts of pale-staining mucin surrounded nests or cords of moderately anaplastic epithelial cells. We couldn't find any evidence of internal neoplasms as a source of metastasis. We resected the tumor with approximately a 1 cm margin and then performed a split thickness skin graft.

Clavicle medial end fracture is rare, and it has not been studied extensively. Although there is debate regarding its treatment methods, because of the complications of conservative treatment, surgical treatment has been considered more than conservative treatment. This study describes a surgical method using double-plate fixation for treatment of clavicle medial end fractures in which plates were used on each anterior and superior border according to the anatomical structure of the clavicle. In addition, we report operative results of three patients treated by double-plate fixation.

To generate drug delivery vector to locales in the body, genetic engineering and expression techniques have been used to produce antibody avidin fusion proteins. Chicken avidin has been fused to mouse-human chimeric IgG3 immediately after the hinge with a flexible linker (H-Flex-Av) and at the end of CH2 (CH2-Av). Fusion heavy chains were expressed with the expected molecular weight, assembled as H2L2 forms with a co-expressed light chain, and were secreted. The expression level of H- Flex-Av was 1~10 ug/ml/10(8)/24 hrs, but that of C2-Av was a very little (0.08~0.9 ug/ ml/10(8)/24 hrs). The resulting H-Flex-Av and CH2-Av fusion proteins continued to bind antigen dansyl and also bound biotinylated bovine serum albumin; both H-Flex-Av and CH2-Av had shown to retain 3-4 times higher relative affinity than that of CH3-Av in ELISA. Importantly the fact that both avidin fusion proteins had a higher relative affinity suggests that these avidin fusion proteins can be effectively used to deliver biotinylated ligands such as drugs and peptides to a certain locale, such as the brain.
