Mullerian Mucinous papillary Cyatadenernas of Borderline tumor(MMBT) is lined by mucinous epithelium of endocervical type and is characterized by papillae architecturally similer to those of serous horderline tumors, It has been described rarely in the literature, Thia case was reported with a brief review of the concerened literatures. It has important clinical and pathological diBerences from mucinous birderline tumors with intestinal differentiation, but has many similatities to mixed epithelial borderline tumora of Mulierian type. Recently, a case of MMBT in a 22 years old woman was experienced at our department. We presented this case with a brief review of literature.

BACKGROUND: Oculocutaneous albinism (OCA) is a genetic disorder of the melanin pigment system in which melanin synthesis is reduced or absent in the skin, hair, and eyes. OCA is classified into two major types, and tyrosinase-related OCA can be produced by mutations of the structural gene for tyrosinase enzyme (TYR gene). OBJECTIVE: The purpose of this study was to analyze the segregation of mutant alleles of the TYR gene in tyrosinase-negative and tyrosinase-positive Korean OCA patients and families. METHODS: We amplified exon I, II, and III of the TYR gene of Korean OCA patients and their families by polymerase chain reactions (PCR), and analyzed the mutations by restriction fragment length polymorphism (RFLP) analysis in exon I and single-strand conformation polymorphism (SSCP) analyses in exon II and exon III. RESULTS: Two tyrosinase-negative cases showed mutations in exon I. Four tyrosinase-nega-tive cases and one tyrosinase-positive case showed mutations in exon II, and one tyrosinase-neg- ative case showed mutations in exon III. In summary, we found three kinds of mutation in four tyrosinase-negative OCA patients and one tyrsinase-positive OCA patient. CONCLUSIONS: RFLP and SSCP analysis can provide a basis for a rapid and sensitive screening system to detect TYR gene mutations of Korean OCA patients and their families.

BACKGROUND: Defective adhesion and migration of melanocyte may be involved in pathogenesis of vitiligo. Tenascin, a glycoprotein of the extracellular matrix, has a role in cell adhesion and migration. It has been reported that abundant expression of tenascin in vitiligo lesion may inhibit melanocyte adhesion and migration. OBJECTIVE: To investigate the tenascin expression in vitiligo skin lesions and to compare with clinical findings. METHODS: We studied 9 patients with vitiligo. The expressions of tenascin were studied by immunahistochemieal techniques.

BACKGROUND: Atopic dermatitis, characterized by dry, flasky, easily irritated skin, is the most common form of dermatitis seen during childhood. Infants with atopic dermatitis and other eczematous conditions need special dermatologic care to hydrate their skin and to minimize contact with irritants or allergens. OBJECTIVE: The purpose of our study is to evaluate the safety and efficacy of the skin products developed for children. METHODS: Twenty-eight normal children and 26 children with atopic dermatitis were evaluated clinically after using following commercal skin products : (lotion, cream, shampoo, soap, face wash wash) for 2 weeks. Water content of the skin of 14 volunteers was measured serialy over 8 haurs at 2 hour intervals after the application of each skin product. The skin pH of 16 volunteers was also measured serialy over 60 minutes at 30 minute intervals after application. We performed visual skin erythema grading, skin erythema grading by dermaspectrometer, transepidermal water loss measurement, skin water content measurement, and keratinocyte morphology observation by D-squame after the application of the skin products to 13 volunteers for 4 days.

A clinocostatistical observation was made on 191 cases of inpatients & 42 cases of out-patients, who had beem admitted or controlled but to streptococcal infections & its related diseases at the Department of pediatrics, N.M.C. from Jan. 1971 to Dec. 1977. The results were obtained as follows: 1) The streptococcal infections occupied 3.6% of all the inpatients(5,317) during the period. Among 233 cases, 137 cases(58.8%) were male. The annual incidence was between 1.9% and 4.2%. 2) The related disease entities were acute glomerulonephritis (70.8%), rheumatic fever (18.4%), Henoch-Sh?lein purpura (3.9%), acute tonsillitis (1.7%), scarlet fever (1.3%) and others in order. 3) The peak age incidence was between 7 to 9 year and the seasonal incidence showed prevalance in cold months from October to February. 4) The URI was the most common preceding event both in acrte glomerulonephritis (53.9%) & rheumatic fever (39.5%). 5) The mean interrval between the onset of streptococcal infections and its related diseases of acute glomerulonephritis & rheumatic fever were 6 to 10 days & 11 to 15 days, respectively. 6) The main symptoms of over all streptococcal infections were fever, edema, proteinuria, hematuria & throat injection. 7) Lab. Data showed elevated E.S.R. in 59.7%, leucocytosis in 41.6%, increased ASO titer in 96.6% & positive CRP in 79.4% of the cases. Positive culture from throat swab, CSF or pus were obtained in 18.1% of the cases.

The androgen insensitivity syndrome is a heterogeneous disorder with a wide spectrum of phenotypic abnormalities, ranging from complete female to ambiguous forms that more closely resembles males. Mutations of the androgen receptor gene are responsible for a variable degree of impaired androgen action. The complete androgen insensitivity syndrome is characterized by normal female external appearance in spite of the normal male karyotype 46XY with testes and normal testosterone production and metabolism. This is transmitted by X-linked recessive manner. Wolffian duct does not develop. However, m llerian development does not occur in presence of antim llerian hormone activity. Recently we experienced a case of complete androgen insenditirity syndrome. We reported a case with concerned literatures.

BACKGROUND: This randomized, controlled study was designed to compare the effects of recruitment maneuvers (RMs) with a 15 cmH₂O positive end-expiratory pressure (PEEP) on the systemic oxygenation and lung compliance of patients with healthy lungs following robot-assisted laparoscopic prostatectomy (RALP). METHODS: Sixty patients undergoing a RALP with an intraoperative 15 cmH₂O PEEP were randomly allocated to an RM or a Control group. The patients in the RM group received a single RM through the application of a continuous positive airway pressure of 40 cmH₂O for 40 s 15 min after being placed in the Trendelenburg position. The arterial oxygen tension (PaO₂, primary endpoint) and the pulmonary dynamic and static compliances (secondary endpoints) were measured 10 min after the anesthetic induction (T1), 10 min after establishment of the pneumoperitoneum (T2), 10 min after establishment of the Trendelenburg position (T3), 10 min after the RM (T4), 60 min after the RM (T5), and 10 min after deflation of the pneumoperitoneum in the supine position (T6). RESULTS: The intergroup comparisons of the PaO₂ showed significantly higher values in the RM group than in the Control group at T4 and T5 (193 ± 35 mmHg vs. 219 ± 33 mmHg, P = 0.015, 188 ± 41 mmHg vs. 214 ± 42 mmHg, P = 0.005, respectively). However, the PaO₂ at T6 was similar in the two groups (211 ± 39 mmHg vs. 224 ± 41 mmHg, P = 0.442). Moreover, there were no statistical differences between the groups in the dynamic and static compliances of the lungs at any time point. CONCLUSIONS: The arterial oxygenation of the patients with a healthy lung function who had undergone a RALP with intraoperative 15 cmH₂O PEEP was improved by a single RM. However, this benefit did not last long, and it did not lead to an amelioration of the lung mechanics.

Between March 1994 and March 1995, 10 patients with thoracolumbar burst fractures underwent a one-stage operation consisting of anterior decompression, reduction, bony fusion with iliac bone and stabilization with Kaneda device. The mean follow-up was 6.4 Months. Most patients with incomplete neurologic lesions showed postoperative improvement and were upgraded one or two steps in the Frankel scale. No patient showed neurological deterioration after surgery. Loss of reduction was 5.5 degree during follow-up period. Anterior decompression and strut fusion was used to effectively recover the neurological deficit and reduce the pain in a thoraco-lumbar burst fracture.
