The nasal ala is a challenging area for surgical reconstruction, with thick sebaceous skin, the lack of an ample tissue reservoir, and an adjacent free margin. Numerous flaps have been reported for the repair of alae defects. A 71-year-old woman with simultaneous basal cell carcinomas involving both nasal alae was treated by Mohs micrographic surgery. The surgical defects measured 1.5x1.5 cm on the center of the right nasal ala and 1.0x1.0 cm on the left nasal ala, including the alar crease and rim. The right nasal ala was used as a nasolabial transposition flap and the left nasal ala was reconstructed by an island pedicle flap. The final shape and texture were satisfactory. The flaps survived and nasal symmetry was preserved. Combined nasolabial transposition and island pedicle flaps thus offer a superior esthetic and functional result owing to minimized tension. This may be a valuable reconstructive option in the repair of bilateral nasal alae defects.

The melanotic neuroectodermal tumor of infancy(MNTl) is a rare, usually benign, pigmented lesion which most frequently involves the maxilla. Skull, brain, and mandible are other craniofacial sites; this anatomic region accounts for 87% of all cases. The vast majority of MNTl, nearly 95%, present in infants of both sexes within the first year of life. Most cases of MNTl follow a benign course, with a 15% propensity for local recurrence. MNTl is regarded as a primitive neuroectodermal tumor with polyphenotypic differentiation. We report a classical MNTl which occurred in left lower maxilla in 6-month old female infant. She developed an ill defined, firm swelling on the left alveolar ridge and gum during 3 weeks. Mass excision reveals ill defined, grayish-tan hard mass, measuring 2.0x1.6 cm. Microscopically, the tumor reveals irregular alveolar pattern of melanin-containing cuboidal cells and nests of small round cells. The immunohistochemical staining for melanoma-associated antigen, neuron-specific enolase and cytokeratin show positive reactions. Ultrastructural examination showed intracytoplasmic melanosome, tonofilament and desmosome.

We report a case of Kyrles disease occuring in a 19-year-old man with chronic renal failure. The patient had multiple hyperkeratotic papules with central plug on the upper extremities, lower extremities and buttocks. Histopathological findings showed epidermal invagination filled with parakeratotic column and basophilic debris. Many dyskeratotic and vacuolated cells were present below the keratotic plug, and penetration of the parakeratotic column into the dermis was seen.

Journal of Korean Society of Medical Informatics 2007;13(1):9-17
OBJECTIVE: This study was conducted to identify 3 to 5 years of future management issues in hospital information systems (HIS). METHODS: Two rounds of interview surveys were conducted based on the sample survey of 50 managers from 28 hospital information centers utilizing the Delphi method. RESULTS: From the survey, management issues in HIS were identified in the following order: 'top management support', 'close relationship with users', 'PACS', 'disaster recovery', improving IS strategic planning'. Compared with the 1999 survey, the issues that rank within the top 10 management issues were as follows: 'top management support', 'security and control', 'close relationship with users'. Recently surfaced issues are 'disaster recovery' and 'standardization'. The issues that dropped out of the top 10 ranks were 'network management', 'recruiting and developing IS human resource'which were very fundamental issues in the initial state of the introduction of the hospital information system. CONCLUSION: The two main significance of this study involves predicting future management issues based on the comparison of the current issues with the 1999 issues and recommendingmanagement strategies based on the classification of issues by importance and persistence.

The investigation of systolic time intervals and hemodynamics was performed in 42 patients with liver cirrhosis by noninvascive methods. The patients were divided into four groups according to the presence or absence of anemia and/or ascites: i.e. group I; cirrhosis without anemia and ascites, group II; cirrhosis with ascites only, group III; cirrhosis with anemia only, and group IV; cirrhosis with ascites and anemia. In the resting state of the patients, the systolic time intervals and hemodynamic data were measured by the high speed simultaneous recordings of electrocardiogram, phonocardiogram, carotid and femoral arterial pulse tracings, and compared with those obtained from 155 normal adult subjects. 1. The pulse were increased considerably in group IV, and diastolic blood pressure was elevated in group II with significance. 2. The stroke volume and cardiac output were increased significantly in group III. 3. The peripheral resistance was reduced particularly in group III, and the volume elasticit coefficient was decreased in group IV. 4. The QS1 interval was prolonged significantly in group II and IV, but QS1 interval corrected by multiple regression equation proposed by our laboratory (illustrated in the text) did not show significant difference compared with that of normal subjects. 5. The left ventricular ejection time(LVET) and total electromechanical systole(QS 2) appeared to be shortened in group II and IV, but the corrected LVET and QS 2 were not different significantly from those of the normal subjects
