The autogenous fascia graft has been used for various surgical purposes because it has good durability, a gliding capacity, elasticity and a high survival rate. However, few studies have reported histological changes of the graft in various situations. This study attempted to determine histomorphologic changes after autogenous fascia graft in various surgical conditions. The results revealed were as follows: 1. The tension applied to grafts plays the key role in the survival rate of autogenous fascia grafts. 2. Rolling the fascia reduced the volume and weight after autogenous graft due to fibrosis and central fatty degeneration. 3. Autogenous fascia graft covering silicone blocks showed its fascial structure and reduction of the formation of fibrous capsule around the silicone.

BACKGROUND: The Q-switched ruby laser has recently shown that it can remove tattoos with-out scarring. Therefore the Q-switched ruby laser is expected to be effective in the treatment of nevus of Ota, which contains pigmented cells in the dermis. OBJECTIVE: The purpose of this study is to evaluate the efficacy of Q-switched ruby laser in the treatment of nevus of Ota. METHODS: Twenty-five patients (6 men, 19 women) with nevus of Ota on the face were treat-ed. The age of the patients ranged from 3 to 62 years. The energy fluence used varied from 6 to 8.5 J/cm². Treatment intervals ranged from 1 to 3 months, and the number of treatments ranged from 2 to 9. Photographs were taken of all patients before and on every return visit. The photographs were then compared with each other. After completion of treatment, we evaluated some parameters including the extent of pigment-free area within the skin lesions (score 0-4), degree of lightening in the remaining skin lesions (score 0-3), and patient's own or their parents' opinions on the result of treatment (score 0-3). The scores of the above three parameters were added and the resulting scores were designated as excellent (score 9-10), good (score 7-8), moderate (score 5-6) and poor (score 0-4). RESULTS: Excellent treatment response (score 9-10) was obtained in 6 of the 25 patients. In all patients disappearance of pigmentation on a 40 percent or larger area was seen. One month after completion of treatment, the remaining lesion size was less than 40 percent of the original lesion in 21 (84.0%) patients. The degree of lightening in the remaining lesion was marked (score 3) in 22 (88%) patients. No scarring was noted following treatment. Transient hyperpigmentation was noted in 7 patients, and transient hypopigmented areas were noted in one patient. CONCLUSION: Q-switched ruby laser appears to be an effective and safe modality for the treatment of nevus of Ota.

BACKGROUND: Phadiatop test which was developed for screening of atopy in eastern asia area, has not been sufficiently evaluated in Korea. In our previous study, the clinical usefulness of Phadiatop test for screening of atopy was evaluated on atopics and non-atopics defined by the results of skin prick tests with 10 inhalant allergens in Korea. In this study, we evaluated the usefulness of Phadiatop test for screening of atopy based on the level of CAP specific IgE in Korean asthmatics. METHODS: On 136 Korean asthmatics, the level of CAP specific IgE to 10 important inhalant allergens and the level of Phadiatop specific IgE to mixture of 8 important inhalant allergens in Korea were measured. Atopics and non-atopics were defined by the results of CAP specific IgE and the sensitivity, specificity, predictive value of a positive and negative result, and concordance rate of Phadiatop test were estimated. RESULTS: The sensitivity, specificity, predictive values of a positive and negative result, and concordance rate of Phadiatop test were 90.5%, 95.0%, 99.1%, 63.3%, and 91.2%, respectively. CONCLUSIONS: Phadiatop test was very sensitive, rapid and convenient, and corresponded well to the results of CAP specific IgE. We concluded that Phadiatop test is very useful as a screening tool of atopy in Korea.

BACKGROUND: Video-assisted thoracic surgical procedure via thoracoscopy has recently gained popularity, as it avoids a thoracotomy, reducing intraoperative blood loss, postoperative pain, respiratory dysfunction and hospital stay. However, to visualize adequately the intrathoracic structures, creation of artificial pneumothorax by carbon dioxide insufflation during thoracoscopy would cause significant hemodynamic compromise. The aim of this study was to evaluate the effect of CO2 insufflation into the pleural cavity on the hemodynamics and the arterial blood gas tension under general anesthesia. METHODS: Twenty-five patients, after intubation with single lumen endotracheal tube, underwent enflurane (1~2%) and N2O-O2 (1:1) general anesthesia. Before placement of a thoracoscope, the baseline mean arterial pressure and heart rate were obtained. Measurements were taken at 5, 10, and 20 min. after the beginning of carbon dioxide insufflation (3~5 mmHg) and 10 min. after gas evacuation. Blood gas analyses were done before, during CO2 insufflation and after CO2 evacuation. Data were analyzed using Student t-test. RESULTS: Positive-pressure CO2 insufflation (3~5 mmHg) caused a decrease of mean arterial pressure (5~7%) and an increase of airway pressure (1.5 times) and heart rate (13~20%) throughout the gas insufflation period (p<0.05). Blood gas analyses revealed no significant change. CONCLUSIONS: These results suggest that low CO2 insufflation pressures (3~5 mmHg) may cause cardiovascular depression during thoracoscopy. Therefore careful monitorings should be done during this procedure.

We report a rare case of glomangiomyoma in a 25-year-old man who had an asymptomatic, 1.5 × 1.5cm sized, round, skin-colored, soft mass on the right cheek. Histopathologically, the lesion was consistent with glomangiomyoma which showed irregularly dilated vessels lined by endothelial cells and several outer layers of glomus cells, and smooth muscles distributed within the tumor. The tumor cells were characterized immunohistochemically by the presence of smooth muscle actin, muscle specific actin, and vimentin. To our knowledge, this is the first case report of glomangiomyoma on the facial location in the Korean literature.
