Opacification of the gallbladder after parenteral administration of contrast material usually indicates diminished renal function but can occur with normal renal function. The authors recently experienced 13 cases of such vicarious excretion of contrast media. Among 13 patients. 9 patients had renal disease unilateral ureteral stone(n=3), staghorn calculi(n=2), acute renal failure from sepsis(n=1), renal contusion(n=2) and unilateral renal artery involvement by dissecting aortic aneurysm(n=1). Of these 9 patients, 3 patients showed abnormal serum creatinine levels at the time of presentation or shortly thereafter. In 6 patients, injection of a large amount of contrast media was possibly the additional cause of vicarius excretion. There was no detectable cause in the remaining 4 patients. Heterotopic excretion of contrast media is clearly a complex phenomenon, the reason for which it is difficult to establish with certainty in each individual case. Anyhow, vicarius excretion of contrast media occurs more frequently than previously thought, and it can occur not only with abnormal renal function but with normal function also.

Since the discovery of U. urealyticum in human. the etiologic role of this microbe to urogenital tract infection has been investigated. U. urealyticum is one of the etiologic agents for such infections of human urogenital tract as nongonococcal urethritis. prostatitis. cystitis. infertility. interauterine infection, in which standard bacteriologic investigation had failed to indicate bacterial infection. We studied the occurrence of U. urealyticum in urogenital tract of persons in the district of Pusan. From March, 1990 to June. 1990, 290 heterosexual patients and 102 normal control were cultured for U. urealyticum. The results were as follows : l. Overall incidence of this organism was 19.3%, 32.2% from urethral swab and 10.5% from urine, which was lower than that of control group. 2. The incidence of this organism in Females (32.7%) was generally higher than that in males ( 16.6%). 3. This microbe was well detected in middle age person. 4. This microbe was higher detected in specimen from urethral swab (32.2%) than urine (10.5%). 5. The isolation ratio in local private clinics was lower than that in Kosin medical center. 6. Erythromycin had the best sensitivity against U. urealyticum followed by streptomycin. But tetracycline and oxytetacycline were highly resistant to this organism.

Confluent and reticulated papillomatosis(CRP) is a rare dermatosis. The lesions are hyperkeratotic, verrucous papules and plaques, resulting in a confluence of lesions centrally and a reticulated pattern at the periphery. It is more common in women and during puberty. The histopathological findings show papillomatosis, hyperkeratosis and a sparse superficial perivascular lymphocytic infiltrate. We report a case of CRP that responded to oral etretinate in an 18-year-old man.

Acquired tufted angioma is a benign, progressive vascular lesion that has a distinctive histopathologic appearance. We report a 31-year-old man with acquireed tufted angioma. Several reddish papules and plaque were present on the neck. The lesion had been present for 6 months. They had enlarged slowly, and were slightly tender. Histopathologic examination of the biopsy specimen showed round to ovoid cellular tufts of capillaries, most prominent in the middle to lower dermis.

BACKGROUND: The histogenesis of acquired melanocytic nevi is still a matter of debate. One considers that nevus cells originate from epidermal melanocytes and the other postulates that nevus cells are of both neural and melanocytic origin. OBJECTIVE: To clarify this controversy, investigation of the growth dynamics and tissue homeostasis of nevi is needed. METHODS: We compared expressions for PCNA and bcl-2 in 12 intradermal nevi and 8 compound nevi by immunohistochemical staining. RESULTS: The results are summarizid as follows: 1. bcl-2 : Both intradermal and compound nevi exhibited strong perinuclear and cytoplasmic staining. There was diminution of staining with progressive descent into the dermis. 2. PCNA : The mean rate of PCNA-positive nevus cells was higher in compound nevi than in intradermal nevi. CONCLUSION: The findings of our study shows considerable differences between intradermal nevi and compound nevi in expressions for PCNA and bcl-2.

Prediction f chemical composition of gallstones is a prerequisite in contemplating the chemical dissolution or extracorporeal shock wave lithotripsy of gallstones. The author retrospectively analysed the correlation between quantitative chemical composition of gallstones and their ultrasonographic and computed tomographic findings. The ultrasonography(US) and computed tomography(CT) of 100 consecutive stones obtained from 100 patients were performed under the in vitro condition. Their US and CT fingings were grouped with certain patterns and each group was compared with the chemical composition of the stones. Stones with entirely discernible cirumsference and homogeneous internal echo on US had high bilirubin and low cholesterol content. Acoustic shadows were frequently absent with those stones. Stones with variable internal echo on US had relatively high cholesterol content but their distribution range were wide. There was no correlationship between the cholesterol content and the CT No. of the gallstones. There was positive correlationship between the calcium content and the CT No. of gallstones. The near totally calcified gallstones had very low cholesterol and high residue content. There was no relationship betweenthe calcification type and the ultrasonographic pattern. In conclusion, those stones with entirely discernible circumsference and homogeneous internal echo on US were pigment stones. On the contrary, stones with variable internal echo had relatively high cholesterol content. CT could predict the calcium content with CT No., but could not predict the cholesterol content.

BACKGROUND: A number of skin manifestations in patients with allergic contact dermatitis result from sensitization with specific allergens, and patch testing is used as a diagnostic means of identifying theses allergens. In Korea, the commercial patch test panel, the TRUE-test, has been available since 2005. However, there have been few reports regarding the results of the TRUE-test. OBJECTIVE: The purpose of this study was to analyze the type, frequency, and changes in common contact allergens in Korea using the TRUE test. METHODS: A total of 311 patients with allergic contact dermatitis were evaluated by the TRUE test between January 2007 and December 2011 at Soonchunhyang hospital. Patch test reading was performed on day 2 and day 4. RESULTS: A total of 311 cases of TRUE test records (male 79, female 232) were compiled and analyzed. The highest age distribution was the 4th decade in females. The face, with exception of the lips, was the most frequently affected site (40.2%). Overall, 58.8% of patients had at least on positive reaction, and the most common allergens were nickel sulfate (31.8%), p-phenylenediamine (13.5%), cobalt chloride (10.0%), thiomersal (7.4%), and carba mix (5.5%). Nickel allergen displayed higher positive rates than the rates in other countries. CONCLUSION: There was no significant difference in the overall positive rate of patch test results compared with recent studies. However, we confirmed that metal-related allergens remain the most common, and that the results provide the basis for the use of the TRUE test in patients with contact dermatitis in Korea.

BACKGROUND: The causative organisms and clinical characteristics of dermatophytoses are altered by various factors such as social environmental change and geographic distribution. OBJECTIVE: The purpose of this research is to investigate the changes and recent clinical and mycological features of dermatophytoses in the Chungcheongnam-do province. METHODS: We performed clinical and mycological studies on 387 cases of dermatophytoses among outpatients of Dermatologic clinic of Soonchunhyang University Cheonan Hospital for 5 years, from January 2008 to December 2012. RESULTS: 1. The age distribution showed patients in their 50s to be the most common. The ratio of male to female was 1.07:1. 2. The seasonal prevalence of dermatophytoses was highest in the summer, but the incidence of tinea capitis was highest in the winter season. 3. The positive rate of KOH examination was 95.1% and that of culture was 58.9%. 4. Trichophyton(T.) rubrum was most prevalent dermatophyte (71.1%), followed by Microsporum(M.) canis (9.2%), T. mentagrophytes (7.9%). CONCLUSION: Compared with previous study, the incidence of T. rubrum infection is rising and in recent years the prevalence of M. canis infection has markedly increased. The rest of causative organisms' proportion is increasing and diversification is observed.
