Smooth muscle hamartoma was first described by Stokes in 1923 as the disease characterized by increase of well-defined bundles of smooth muscle fibers in the dermis. It can be either congenital or acquired. Acquired ones are aften in association with Becker's nevus. We present a case of acquired smooth muscle hamartoma that did not show any pigmentation or hair growth.

PURPOSE: This study conducted to identify the effect of learning organization construction and learning orientation on organizational effectiveness among hospital nurses. Method: Data was collected from convenient sample of 296 nurses who worked for the major hospitals in Seoul, Gyeonggi-do and Gangwoen-do. The self-reported questionnaire was used to assess the general characteristics, the level of the learning organization construction, learning orientation and organizational effectiveness. The data were analyzed using descriptive statistics, pearson's correlation coefficient and multiple regression. Result: The mean score of learning organization construction was 3.61(+/-.32), learning orientation got 3.26(+/-.39), and organizational effectiveness obtained 3.38(+/-.42). The learning organization construction affects of organizational effectiveness by 44.18% and learning orientation by 37.43%. CONCLUSION: This finding indicates that learning organization construction and learning orientation affects the nurses' organizational effectiveness in hospital.

The sea hare is a marine mollusk in the family Aplysiidae that has long been consumed as food. Rarely, toxic hepatitis can occur after eating sea hare. We herein discuss four cases of toxic hepatitis due to sea hare ingestion and review the relevant literature.

Sebaceous trichofolliculoma is a rare appendageal tumor that usually present as a solitary tumor mainly on the nose. Histologically it shows a large, irregularly shaped, centrally located cavity lined by squamous epithelium and radially arranged pilosebaceous follicles connected to the cavity. We describe a case of sebaceous trichofolliculoma in an 86-year-old woman who presented with asymptomatic skin-colored papule on her nose.

Onychomycosis is caused by dermatophytes usually, but some species of nondermatophytic molds and yeasts are also associated with invasion of nails. Aspergillus sydowii is a nondermatophytic mold which is opportunistic filamentous fungus in all environments. We report a case of onychomycosis caused by A. sydowii in a 65-year-old male. The patient showed yellowish discoloration with hyperkeratotic change on the distal and lateral portion of both great toenails. Direct microscopic examination of scraping on the potassium hydroxide preparation revealed dichotomous septate hyphae and repeated cultures on Sabouraud dextrose agar showed the same blue green velvety colonies. Biseriate phialides that cover entire vesicle with conidial structure resembling Penicillium were shown in the slide culture. The DNA sequence of internal transcribed spacer (ITS) region of clinical sample was 99% match to that of A. sydowii strain XWSFJJ1 (GenBank accession number FJ461692). We confirmed A. sydowii by KOH mount, colony, light microscopic morphology and DNA sequence analysis. The patient was treated with 250 mg oral terbinafine daily and topical 5% amorolfine nail lacquer for 3 months.

Lymphangioleiomyomatosis(LAM) is a rare disease of unknown etiology that occurs mainly in woman in her reproductive age. We recently experienced two cases of bilateral diffuse cystic lesion of the lung on chest X-ray and HRCT. The first case, a 26-year-old female, who had been diagnosed with tuberous sclerosis be the presence of clinical manifestation such as mental retardation, bilateral renal angiomyolipoma, adenoma sebaceum and generalized seizure, was admitted due to recently developed hemoptysis. Chest PA showed diffuse ground-glass opacity with radiolucent cystic lesions of various sizes on both lung fields. HRCT showed innumerable small cystic lesions with suspicious diffuse ground-glass opacity on both lung fields. The second case, a 30-year-old female was admitted due to dyspnea and spewing of blood-tinged sputum for 2 weeks, shortly after delivery. Chest PA showed diffuse reticular and ground-glass opacities on both lung field. HRCT showed multiple well-difined and relatively uniform size air cysts with a uniform wall thickness on entire both lung fields, with small amount of right pleural effusion. By thoracoscopic lung biopsy she was diagnosed with pulmonary lymphangioleiomyomatosis. We report these cases with a brief review of the literatures.

We report here a case of maternal 3-methylcrotonyl-coenzyme A carboxylase (3-MCC) deficiency in a Korean woman. Her 2 infants had elevated 3-hydroxyisovalerylcarnitine (C5-OH) on a neonatal screening test by liquid chromatography-tandem mass spectrometry (LC-MS/MS), but normal results were found on urine organic acid analysis. The patient was subjected to serial testing and we confirmed a maternal 3-MCC deficiency by blood spot and breast milk spot test by LC-MS/MS, serum amino acid analysis, urine organic acid and molecular genetic analysis that found c.838G>T (p.Asp280Tyr) homozygous mutation within exon 9 of the MCCB gene. Especially, we confirmed marked higher levels of C5-OH on breast milk spot by LC-MS/MS, in the case of maternal 3-MCC deficiency vs. controls.

Twin-to-twin transfusion syndrome (TTTS) is one of the complications showing high mortality rate in monochorionic twins with vascular communication in the placenta. Clinical manifestations of TTTS are usually characterized by polyhydramnios, circulatory overload, cardiac failure and fetal hydrops in the recipient twin and symmetrical fetal growth restriction, oligohydramnios, hypovolemia and anemia in the donor twin. TTTS occurres in 10-35% of monochorionic twins. We report three cases of TTTS with fetal hydrops in which amnioreduction was serially attempted and maternal digoxin treatment was tried for the therapeutic purpose.
