A female newborn had the following characteristics; a congenital localized absence of skin over the lower extremities; blistering of the skin or mucous membrane, incited by trauma, which heals without scarring; and congenital absence or deformity of the nails. In respect to the characteristic manifestation, clinical course and electron microscopic features, our patient seems to fit well into Bart's syndrome. The inheritance pattern appears to be autosomal dominant but, as in this report, isolated cases have been recognized. As the review of the literatures, congenital localized absence of skin has been observed in various subsets of inherited E.B. But, we believe that the term Bart's syndrome should be used to identify patients with good prognosis as the Bart's initial description To the best of our knowedge, this is the first reported case of Bart's syndrome in the korean literature.

BACKGROUND: We conducted this study to verify whether a mechanical ventilator is adequate for cardiopulmonary resuscitation (CPR). METHODS: A self-inflating bag resuscitator and a mechanical ventilator were used to test two experimental models: Model 1 (CPR manikin without chest compression) and Model 2 (CPR manikin with chest compression). Model 2 was divided into three subgroups according to ventilator pressure limits (P(limit)). The self-inflating bag resuscitator was set with a ventilation rate of 10 breaths/min with the volume-marked bag-valve procedure. The mode of the mechanical ventilator was set as follows: volume-controlled mandatory ventilation of tidal volume (Vt) 600 mL, an inspiration time of 1.2 seconds, a constant flow pattern, a ventilation rate of 10 breaths/minute, a positive end expiratory pressure of 3 cmH2O and a maximum trigger limit. Peak airway pressure (P(peak)) and Vt were measured by a flow analyzer. Ventilation adequacy was determined at a Vt range of 400-600 mL with a P(peak) of < or = 50 cmH2O. RESULTS: In Model 1, Vt and P(peak) were in the appropriate range in the ventilation equipments. In Model 2, for the self-inflating bag resuscitator, the adequate Vt and P(peak) levels were 17%, and the P(peak) adequacy was 20% and the Vt was 65%. For the mechanical ventilator, the adequate Vt and P(peak) levels were 85%; the P(peak) adequacy was 85%; and the Vt adequacy was 100% at 60 cmH2O of P(limit). CONCLUSIONS: In a manikin model, a mechanical ventilator was superior to self-inflating bag resuscitator for maintaining adequate ventilation during chest compression.

Eosinophilia-myalgia syndrome(EMS) is a systemic illness that occurred as an epidemic by ingestion of over-the counter L-tryptophan preparation in the United States in October 1989. We report a Korean case of EMS not associated with the ingestion of either L-tryptophan or other nutritional supplements such as lysine and niacin.

Idiopathic atrophoderma of Pasini and Pierini(IAPP) is an uncommon condition of unknown etiology and typically affects persons in the second and third decades of life. IAPP consists of asymptomatic grey to brown depressed lesions with "cliff drop" borders, which are usually bilateral and located on the trunk. A 40-year-old woman visited our department because of unilateral atrophic lesions on the abdomen, right arm, and posterior aspect of right thigh for 20 years. Laboratory evaluations were normal and histologic examination revealed significantly decreased thickness in dermis. We report an unusual case of idiopathic atrophoderma of Pasini and Pierini presenting unilateral distribution.

PURPOSE: The purpose of this paper is to discuss the characteristic CT and MR findings in persistent hyperplastic primary vitreous(PHPV) and to compare the detectability of those findings in each modality. MATERIALS AND METHODS: We retrospectively evaluated CT and MR findings in 32 patients with PHPV. Twenty-five patients had CT, 13 patients had MR, and 6 patients had both CT and MR. RESULTS: Major findings of PHPV in 32 patients on both imaging modalities were lens deformity(78%), shallow anterior chamber(72%), heterogeneous vitreous opacity(72%), enhancing hyaloid artery or remnant of fibrotic hand(69%), and microophthalmos(67%). Minor findings were retinal detachment(22%), and vitreous hemorrhage(6%). In MRI, lens deformity(92%) and shallow anterior chamber(85%) were detected most commonly whereas in CT, opaque vitreous(80%) was the most common finding. Findings of enhancing hyaloid vessel or remnant of fibrotic band, considered characteristic of PHPV, were more commonly detectable in MR (85%) than CT(52%). CONCLUSION: Characteristic MR and CT findings of PHPV were lena deformity, shallow anterior chanber, heterogeneons vitreons opacity, enhanciny hgalind artery or remnant fibrotic band, and microphthalmos. MR seemed to be more useful than CT in detecting Globe pathology.
