Aplasia cutis congenita is a rare disorder characterized by localized or generalized absence of skin at birth. The various hypothesis and classification are proposed. Type V in Frieden's classification, which is associated with fetus papyraceus or placental infarcts, occurs as a large cutaneous defect on the trunk and extremities. We experienced the patient had skin defect affecting the lower abdomen symmetrically, with no family history of the any disorders or chromosomal anomalies and associated anomalies. A twin fetus was died in utero. We report a case of aplasia cutis congenita associated with fetus papyraceus with the review of the associated literatures.

The thirty eight newborn infants with periventricular leukomalacia who were admitted to the neonatal intensive care unit of Gil General Hospital from March 1, 1988 to June 30, 1991, were investigated for ultrasonographic findings, risk factors and neurological outcome. The results were as follows: 1) There were 38 cases of PVL including 21 echogenic flarings and 17 cystic PVL's. 2) Mean birth weight was 2,250 gm and mean gestational age was 35 week. 3) Mean detection timing was 4th day in echogenic flarings and 18th day in cystic PVL's. 4) PVL's were located in the parietal region in 1 case and fronto-parieto-occipital in 3 cases. 5) Mean cyst size was 6 mm. 6) Multiple logistic regression analysis for the risk factors of PVL showed that low birth weight, apnea and seizure were the most significant contributing factors (p<0.05). 7) In the follow-up study of cystic PVL's, 7 cases showed improvement, 7 cases developed into multicystic encephalomalacia and 3 cases developed into atrophy. 8) Neurodevelopmental outcome of cystic PVL's showed nomal; 6.2%, minor neurodevelopmental defect; 43.8%, major neurodevelopmental defect; 31.2% and death; 18.8%. 9) Neurosonographic predictability for neurodevelopemental sequelae by cystic PVL's showed sensitivity; 63.6%%, specificity; 98.0%, positive predictive value; 92.8% and accuracy; 88.2%. 10) Major neurodevelopmental defect was more frequent, cyst size being larger and location being more extensive (p<0.05).

OBJECTIVE: The involvement of IGF system in hyperandrogenism and abnormal follicular development is controversial. This study is to assess whether IGF system contribute to it in the women with polycystic ovary(PCO). METHODS: Baseline serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol (E2), testosterone (T), androstenedione (ADD), prolactin, thyroid stimulating hormone (TSH), free insulin-like growth factor(IGF)-I, free IGF-II, insulin-like growth factor binding protein(IGFBP)-1, and IGFBP-3 were measured in twelve healthy regularly cycling volunteers and forty-two women with PCO then, the changes of baseline serum levels were evaluated after laparoscopic ovarian electrocauterization in nine PCO patients. In addition, the expression pattern of IGF-I and IGF-II was examined in the ovary of control and PCO group. RESULTS: Baseline levels of LH, ADD, free IGF-II, and IGFBP-3 were significantly higher in PCO group. However, there were no significant differences in the levels of free IGF-I and IGFBP-1, although free IGF-I showed decreasing tendency in PCO group. And there was a significant positive correlation between the LH and free IGF-II level in the PCO(P=0.011, r2=0.3899), but not in the control. After ovarian electrocauterization, LH, T, and ADD levels decreased, and free IGF-I and IGFBP-3 level increased. While free IGF-II and IGFBP-1 level showed no significant changes. In the ovary, expression of both IGFs showed similar pattern in normal and PCO ovaries. CONCLUSIONS: The elevated IGFBP-3 level may alter the bioavailability of IGF(s) in the PCO. The change in IGF-I level and resumption of ovulation after electrocauterization, suggest a possible role of IGF system in the impairment of follicular development in the PCO.
