BACKGROUND: As people have been interested in healt,h and as the microcomputers with multimedia steeing have been supplied more and more, there is increasing need of multimedia information about health. The CD-ROM, which is a representative multimedia tool, is capable of interacting between information-provider and users, offering audiovisual interface, and saving great deal of knowledge. METHODS: We developed the health-information system to provide ordinary people with hea1th information using multimedia tools. It, has 7 parts ; self-diagnosis, exploring human body, drug information, hospital information, first-aid treatment, Q and A, and medical common sense. We got image data such as figures, photos, X-rays, electrocardiograms and pathologic specimens with scanner and film scanner, also moving image(video) with video-capturing program. RESULTS & CONCLUSIONS: We hope the multimedia health-information system to become a useful methodology of patient education and to be used as an information source in medical information network in the near future.

OBJECTIVES: This study investigated the effects of the color components of light-cured composite resin before and after polymerization on degree of conversion (DC) and biaxial flexural strength (FS). MATERIALS AND METHODS: Four enamel shades (A1, A2, A3, A4) and two dentin shades (A2O, A3O) of Premisa (Kerr Co.) and Denfil (Vericom Co.) were evaluated on their CIE L*, a*, b* color components using the spectrophotometer before curing, after curing and at 7 day. The DC of same specimens were measured with Near-infrared spectrometer (Nexus, Thermo Nicolet Co.) at 2 hr after cure and at 7 day. Finally, the FS was obtained after all the other measurements were completed at 7 day. The correlations between each color component and DC and FS were evaluated. RESULTS: The light-curing of composite resin resulted in color changes of Premisa in red-blue direction and Denfil in green-blue direction. The DC and FS were affected by product, time and shade (3-way ANOVA, p < 0.05) and product and shade (2-way ANOVA, p < 0.05), respectively. Premisa only showed a significant correlation between the DC and CIE a* component - before and after polymerization (Pearson product moment correlation, p < 0.05). The FS of Premisa showed significant negative correlations with CIE a* and CIE b* components. CONCLUSIONS: The DC and FS of the light-curing composite resin were affected by the color components of the material before and after polymerization.

Complications after a median sternotomy incision, which is used currently in most open heart surgery, are serious, although it is infrequent. Reconstruction of the sternal defect resulting from dehiscence of median sternotomy is still big challenge to the most plastic surgeons. Since vascularized greater omentum was transposed to eliminate mediastinal wound problems, many vascularized regional muscle flaps became mainstay in reconstruction of median sternotomy wound. We treated 13 patients with median sternotomy dehiscence between October of 1993 and March of 1998. In two patients, the wound problems were so confined to superficial tissue that debrided and closed primarily. Eleven patients with deep wound infection were managed with vigorous debridement of all necrotic tissues and resultant defects were covered with regional muscle flaps: rectus myocutaneous flap(3) and bilateral pectoralis advancement flap(8). We used the pectoralis major advancement flaps without counter incision at humeral insertion site and the dissections were limited only medial to the anterior axillary line to preserve the axillary fold. In five patients with larger defects, we elevated muscle and cutaneous flaps separately to make these flaps more mobile. Large portion of two rectus abdominis flaps could not survive, whereas pectoralis advancement flaps had mo special wound problems. Only one patient developed fistula due to remained wire, regardless to flap surgery.

Addison's disease is a rare disorder resulted from a chronic deficiency of the adreanl cortical hormone. The clinical manifestations are general weakness, weight loss, hyperpigmentation, hypovolemia with hyponatremia and hyperkalemia. We report a case of Addison's disease in a 60-year-old woman who has experienced slowly progressive weakness, weight loss and generalized cutaneous pigmentation, especially sun exposed area, extensor surface and nail bed for the last, 2 years. On a hormonal assay of the adrenal glands, basal plasma cortisol level was decreased and basal plasma ACTH level was markedly elevated. A chest X-ray showed streaky tuberculous infiltration in left, upper lobe field and adrenal CT scan showed calcific densities of both adrenal glands with nodular enlargement of right adrenal gland. There was a clinical improvement with steroid replacement therapy and anti-tuber- culosis chemotherapy. A nearly normal appearance was obtained after 5 months' treatment.

BACKGROUND: The external jugular vein (EJV) is a useful intravenous (IV) cannulation site for anesthesiologists, although it has a relatively high failure rate. Unlike other central veins, visualization of the EJV is important during IV cannulation, and the Valsalva maneuver distends the jugular venous system. However, the relationship between the maneuver and EJV visibility remains unknown. This study compared EJV visibility before and after the Valsalva maneuver. METHODS: This was a prospective observational study that included 200 participants. After the induction of anesthesia, EJV visibility grade, depth from the skin to the EJV superficial surface (EJV depth), and EJV cross-sectional area (CSA) before the Valsalva maneuver were measured. The same parameters were measured after the Valsalva maneuver was performed. The EJV visibility grade was defined as grade A: good appearance and good palpation, grade B: poor appearance and good palpation, and grade C: poor appearance and poor palpation. RESULTS: Patient body mass index and EJV depth affected the EJV visibility grade before the Valsalva maneuver (p < 0.05), although EJV CSA did not. The Valsalva maneuver distended EJV CSA and reduced EJV depth, although these changes were not correlated with EJV visibility grade. With regard to EJV visibility, 34.0% of grade B cases and 20.0% of grade C cases were improved by the Valsalva maneuver. CONCLUSIONS: Although the Valsalva maneuver improved EJV CSA and EJV depth, it did not greatly affect EJV visibility grade.
