Hydrocephalus is a common malformation of the central nervous system and its cause may be either congenital or acquired. The imbalance between CSF formation and absorption, obstruction of CSF pathways, impaired venous absorption, and over secretion of CSF results in excessive accumulation of the fluid in the ventricles, leading to hydrocephalus. Although ventriculo-peritoneal shunt is regarded as the main and definitive therapy for rapidly progressive hydrocephalus, shunts in newborns have a high failure rate and thus there have been a search for alternative non-invasive techniques. Acetazolamide is a carbonic anhy- drase inhibitor, which acts by reducing production of CSF in the choroid plexus. Admini- stration of acetazolamide will decrease the rate of CSF production, preventing progressive ventricular enlargement. We experienced three cases of neonatal hydrocephalus successfully treated by long-term administration of acetazolamide. Brief review and related literatures were also presented.

BACKGROUND: The immortalized human keratinocyte line, HaCaT cells have been widely used as substitutes for normal epidermal keratinocytes. Recently, reconstruction of a skin equivalent using HaCaT cells showed a multilayered epithelium,but somewhat different tissue architecture as compared with normal epidermis. OBJECTIVE: In this study, using HaCaT cells we tried to reconstruct an epidermis resembling more closely to normal epidermis than the previous results. MATERIALS AND METHODS: HaCaT cells were cultured in air-liquid interface on a recently developed dermal substrated in our laboratory, de-epidermized dermis (DED) raised on fibroblast-populated collagen matrix and the result was compared with those on DED or fibroblast-populated collagen matrix alone. RESULTS: HaCaT cells on the new dermal substrate formed a multilayered epithelium with rete ridges, showing rather orderly cellular organization compared with those on fibroblast-populated collagen matrix. However, horny and granular layers were not observed contrary to normal epidermis. Immunohistochemical studies revealed that differentiation markers such as keratin 1, keratin 6 and involucrin showed the similar pattern to those in HaCaT cells cultured on fibroblast-populated collagen matrix. Markers of terminal differentiation, loricrin and filaggrin were not expressed contrary to normal epidermis. CONCLUSION: These results suggest that organotypic culture HaCaT cells on the dermal substrate combines DED with fivroblast-populated collagen matrix results in incomplete differentiation of HaCaT cells contrary to normal keratinocytes.

4.Anterolateral Mini-open Fixation with a Patch Augmentation for Latissimus Dorsi Tendon Transfer in Irreparable Rotator Cuff Tears: Technical Note.

Latissimus dorsi tendon transfer is a well-established method for treatment of irreparable posterosuperior rotator cuff tears. We report on an anterolateral mini-open technique with a porcine dermal patch augmentation for latissimus dorsi tendon transfer. Use of this technique would result in avoidance of deltoid damage by anterolateral mini-open approach and reduction of failure rate by patch augmentation.

Korean Journal of Clinical Pathology 1997;17(5):847-852
BACKGROUND: The authors studied to estimate the frequency of irregular antibodies and their significance in blood transfusion and antenatal care in Korea. METHODS: Irregular antibodies were tested by immediate saline spin, 37degrees C albumin and antiglobulin test for 2,008 transfusion candidates and 1,047 pregnant women at Severance hospital using commercial screening and identification cells (Dade, U.S.A.). RESULTS: The irregular antibodies were detected in 38 (1.24%) of total 3,055 subjects (transfusion candidates: 0.9%, pregnant women: 1.91%) . In transfusion candidates, the detected antibodies were Lewis antibodies, cold antibodies (anti-M, anti-P 1), Rh antibodies and unspeified warm antibodies, and their distributions were 56%, 22%, 17%, and 5%, respectively. In pregnant women, the detected antibodies were Lewis antibodies, Rh antibodies, anti-Jra, and unspeified warm antibodies, and their distributions were 45%, 45%, 5% and 5%, respectively. At immediate saline phase, 58% of irregular antibodies were detected. At 37degrees C albumin phase, 90% of irregular antibodies were detected and only 10% of irregular antibodies were detected at antiglobulin phase. CONCLUSIONS: Although the prevalence rates of clinically important irregular antibodies were low, 1/1000 of irregular antibodies could not be detected. Therefore, irregular antibody screening should be performed in all pretransfusion test. And, if antibody detection tests are negative, immediate saline crossmaching methods are acceptable in Korea.

Journal of Korean Academy of Nursing 2006;36(1):197-205
PURPOSE: The objective of the study is to analyze the review contents of reviewers for the submitted papers in the Journal of Korean Academy of Nursing in 2003. METHOD: The review contents of the 165 papers were selected 217 papers that were submitted in 2003. Among those 165 papers, the 21 papers belonged to the 'Do not publish' list and 17 papers, 'Revise manuscript and resubmit', list and the 94 papers, 'Publish if revisions are made' list. There are more than two level differences among the four levels of decision in acceptance of publication in 33 papers. RESULTS: The analysis of the review contents for the papers were suggested according to review categories : introduction, method, results, discussion and conclusion. In addition, if papers had more than two levels of review they were rated poor accord or inconsistent. CONCLUSION: For the quality of the academic journal and development of the nursing science, it is important to disseminate and publish the research paper. Therefore, review of the submitted paper is also important. Implications for the profitable review were suggested in the study.

Eccrine spiradenoma is a txnign, painful tumor of the skin, which probably originates in the coil of the eccrine sweat glands and presents a characteristic clinical and pa.hological picture. However recently, the weakness and inconsistency of the enzymes histochemican, actions and electron microscopic findings, and the presence of numerous undifferentiated and indetirn, inate cells suggest a rather low degree of differentiation. We present herein four cases of eccrine spiradenoma which show livrse histopat.hologic characteristics including typical rosette-like structure, ductal structure, vacuar structure and mixed type, respectively. This report may support the premise that eccrine spiridinoma is defived not only from the eccrine duct but also from pluripotential stem cells.
