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.

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.

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.

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.

The cysteine proteases of Paragonimus westermani metacercariae are involved in metacercarial excystment, host immune modulation, and possibly in tissue penetration. In order to clarify the origin of the enzymes, 28 and 27 kDa cysteine proteases in metacercarial excretory-secretory products were purified through the FPLC system using Mono Q column chromatography. The polyclonal antibodies to the enzymes were produced in BALB/c mice. Immunolocalization studies revealed that both cysteine proteases were distributed at the linings of excretory bladder and excretory concretions of the metacercariae. It was suggested that the excretory epithelium of P. westermani undertake the secretory function of metacercarial cysteine proteases, in addition to its role as a route for eliminating waste products.

Subacute cutaneous lupus erythematosus is a recently recognized distinct subset of lupus erythematosus, having characteristics of clinical, pathologic, serologic, irnrnunologic features. We present a case of subacute cutaneous lupus erythematosus in a 29-year-old woman with symmetric, superficial, nonscarring papulosquamous lesion on the face, scalp, and the extensor surface of the upper extremities. She has a mild systemic illness of musculoskeletal complaints. Serologic abnormalities of the patients are positive rheumatoid factor and anti-Ro antibody test, but fluorescent antinuclear antibody test is negative, which is done by the conventional methods uaing rodent tissue for the substrate. The histopathologic finding of the lesion show the sarne general pattern of the cutaneous lupus erythematosus, and lupus band test is positive.

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.
