A household survey was conducted to compare the patterns of morbidity and medical care utilization between medical aid beneficiaries and medical insurance beneficiaries. The study population included 285 medical aid beneficiaries that were completely surveyed and 386 medical insurance beneficiaries selected by simple random sampling from a Dong (Township) in Taegu. Well-trained surveyors mainly interviewed housewives with a structured questionnaire. The morbidity rates of acute illness during the 15-day period, were 63 per 1,000 medical aid beneficiaries and 62 per 1,000 medical insurance beneficiaries. The rates for chronic illness were 123 per 1,000 medical beneficiaries and 73 per 1,000 medical insurance beneficiaries. The most common type of acute illness in medical aid and medical insurance beneficiaries was respiratory disease in medical aid beneficiaries, musculoskeletal disease was most common, but in medical insurance beneficiaries, gastrointestinal disease was most common. The mean duration of acute illness of medical aid beneficiaries was 3.8 days and that of medical insurance beneficiaries was 6.8 days. During the one year period, mean duration of medical aid beneficiaries chronic illnesses was 11.5 months which was almost twice as long compared to medical insurance beneficiaries. Pharmacy was most preferable facility among the acute illness patient in medical aid beneficiaries, but acute cases of medical insurance beneficiaries visited the clinic most commonly. Chronic cases of both groups visited the clinic most frequently. There were some findings suggesting that much unmet need existed among the medical aid beneficiaries. In acute cases, the average number of days of medical aid users utilized medical facilities was less than medical insurance users. On the other hand, the length of medical care utilization of chronic cases was reversed. Geographical accessibility was the most important factors in utilization of medical facilities. Almost half of the study population answered the questions about source of funds on medical security correctly. Most respondents considered that the objective of medical security was affordability. The chief complaint on hospital utilization was the complicated administrative procedures. These findings suggest that there were some problems in the medical aid system, especially in the referral system.

BACKGROUND: There are many predictors of sensitivity to UVR, but controversies exist about their objectivity, correlation between them, and applicability to various races. OBJECTIVE: In 42 healthy volunteers, we assessed the validaty of dose response angle of erythe ma(DRAE) and delayed tanning(DRADT) after UVB irradiation, and also evaluated the correlation hetween dose-response angb s and other predictors of UV sensitivity. METHODS: We measured erythema and melanin index using reflectance spectrophotometer aft,er irradiation of UVB on the back of 42 males. When the erythema index and melanin index were plotted against UV doses for each patient, a dose response curve was obtained. Linear regression analysis was used to calculate the slope of those curves for erythema and delayed tanning, which were called DRAE and DRADl respectively. Also we checked predictots of UV sensitivity such as skin type, MED, MMD, consiitutional and facultative skin color, then analyzed the relation be tween dose response angles and other predictors. RESULTS: Statistically significa it linear regression lines were obtained from 41 subjects regarding to erythema and frorn 31 subjects regarding to delayed tanning. As for the relationship he tween the pvedictors of UV senitivity, only the MED correlated well with DRAE. CONCLUSION: We found that dose response angles, especially DRAE, were an objective and adequate predictor of cutaneous LJV sensitivity, but could not find validity of skin type and skin color in Koreans. A more organized study with a larger number of subjects is needed to clarify the usefulness of the predictors.

BACKGROUND: Diabetes mellitus is a common condition, and the majority of patients have one or more cutaneous complications. Among them, xerosis is well known to be closely related to diabetics. The xerosis is inversely reflected upon skin surface hydration, the state of which can be exactly assessed with various investigating instruments, such as a hydrometer and corneometer. OBJECTIVE: Our purpose was to compare the hydration state of diabetics with normal persons by the use of a corneometer and hydrometer. METHODS: A total of 267 diabetics were asked whether they felt xerosis or pruritus. In a subgroup of 31 patients, the water content was evaluated and compared by the parameters of diabetic severity. Forty-one non-diabetics were selected for the normal control.

We experienced 3 cases of Candida esophagitis in infancy which were diagnosed by esophageal endoscopy. First case, 10 month-old boy with combined immune deficiency had suffered from oral thrush and poor feeding for more than 4 months. Esophageal endoscopy revealed multiple whitish creamy patches on the friable erythematous and necrotic mucosa of the esophagus. He was firstly treated with amphotericin-B but in vain. Then he was treated with fluconazole (5 mg/kg/day) and in a few days oral thrush nearly disappeared and endoscopy after 2 weeks revealed complete healing of the esophagitis. Second case, 6 month-old boy with some cellular immue defect also suffered from oral thrush, poor feeding and intermittent fever. He was treated with fluconazole and oral thrush was imporved. He was discharged without follow up endoscopy. Third case, 4 month-old girl with liver cirrhosis due to infantile cholestasis had Candida sepsis. Esophagitis was found incidentally during the endoscopic examination of esophageal varix. First 2 cases showed multiple small filling defects and decreased motility on esophagography. Candida antigen was not detected in the sera of all 3 cases of candidiasis. We conclude that Candidia esophagitis should be suspected when an infant has been suffering from long-term treatmet-resistant oral thrush and poor feeding and that esophageal endoscopy can be easily performed in infants also and useful in diagnosing esophagitis and assessing the outcome of treatment.

Angioleiomyoma is a rare benign soft tissue tumor that originates from smooth muscle cells and contains thick-walled blood vessels. Few cases of angioleiomyoma have been described at sites other than the extremities and head. The female genital tract is rarely involved. We have experienced a case of retroperitoneal angioleiomyoma with abnormal MRI and CT findings, which was confused with ovarian malignancy.

PURPOSE: To report the clinical manifestation, predisposing factors, microbiological profiles and treatment outcome of infectious keratitis following penetrating keratoplasty (PK). METHODS: Medical records of the post-PK patients later diagnosed with culture-positive keratitis, between January 2003 and June 2008 at our hospital were retrospectively reviewed. RESULTS: Among 228 eyes of 226 patients who previously had PK, 18 eyes (7.89%) of 16 patients developed microbial keratitis. Fifteen patients had a bacterial infection, of which a Streprococcus species was the most common causative microorganism (6 eyes, 33.3%). Three eyes had fungal infection; one case was co-infected with bacteria. Six eyes (33.3%) presented with a suture-related problem, and sixteen eyes (88.9%) had been using topical glaucoma medications. The suture-related problem and use of glaucoma medication were significantly associated with the development of infectious keratitis (p=0.040 and 0.013, respectively). Remission was achieved in all cases within the mean duration of 2.47 months after treatment initiation. However, visual improvement was not achieved in 11 eyes (68.7%) due to graft opacity. CONCLUSIONS: Early identification of predisposing factors and appropriate management at an early stage may prevent the occurrence of graft infection and improve graft survival.

BACKGROUND: It is mandatory to measure the minimal phototoxic dose(MPD) in order to determine adequate irradiation of UV-A in photochemotherapy. However, the measurement of MPD is not easy in some cases due to inadequte size and site of lesions, time and manpower. OBJECTIVE: The purspose of this study was to standardize the minimal phototoxic dose for a vitiliginous lesion. METHODS: The minimal phototoxic dose of UV-A was measured in 82 vitiligo patients. Then we analyzed the MPD according to the sex, age, site of the vitiliginous lesions, duration of disease, and administration route of the photosensitizer. RESULTS: 1. There were no significant differences between exposed and unexposed areas in MPD in both cases of topical and systemic administration of the photosensitiser. 2. There was no significant correlation between disease duration and MPD in both cases of topical and systemic administration of the photosensitiser. 3. In the group of topical application of 8-methoxypsoralen cream, MPD for males and females were 0.53+0.38J/cm2 and 0.48+0.32J/cm2 respectively without significant difference in sex. 4. In the group of systemic administration of 8-methoxypsoralen, there was a significant difference between males and females in MPD. The MPD in males and females were 1.38+0.72J/cm2 and 2.51 + 1.40J/cm2, respectively. 5. In the group of topical application of 8-methoxypsoralen cream, the MPD in 2nd decade patients was the highest(0.80+0.55J/cm2). The MPD had a tendency to decrease gradually as age receded from the 2nd decade. 6. In the group of systemic administration of 8-methoxypsoralen, there was a tendency for the MPD to be increased according to age without statistical significance. 7. MPD in the group systemically administrated with 8-methoxypsoaralen was four-fold to that of the topical application group. CONCLUSION: It may be valuable to keep in mind that there was a statistical differrence in MPD between sexes in systemic administration of the photosensitizer, and that MPD was different according to patients age in the topical application group.

Conventional skin grafts, cultured allogenic epidermal grafts, and autologous epidermal sheet grafts have been used to cover skin ulcers. We report here two cases of autologous epidermal sheet grafts after suction blistering was performed. The first patient was a 25-year-old adolescent who had multiple ulcers on the face after chemical peeling at a skin care center. The second case was a 21-year-old woman who had a 4x4 cm ulcer on the right shin area thought to be pyoderma gangrenosum. We treated these skin ulcers successfully without recurrence using autologous epidermal sheet grafts.

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the most common cause of euvolemic hyponatremia, and many medications have been associated with SIADH. Pregabalin is a drug used for the treatment of neuropathic pain, though common adverse effects include central nervous system disturbance, peripheral edema, and weight gain. However, hyponatremia caused by pregabalin has been rarely reported. Here we report a patient with pregabalin-induced hyponatremia who met the criteria for SIADH; after discontinuation of the drug, his condition rapidly improved. This case can help clinicians diagnose and treat new-onset hyponatremia in patients who recently initiated pregabalin therapy.
