We report a mild variant of hypomelia-hypotrichosis-facial hemangioma syndrome in a 3 month-old female. The patient showed major features of the previously reported cases including flexion deformities of both upper extremities, sparse light colored hair, mid-facial hemangioma and a characteristic facial appearance. Roentgenogram showed radio-humeral synostosis at both elbow joints by which shortening of upper limbs could be anticipated. However, intra- and extrauterine growth retardation were not remarkable and the lower limbs were not affected.

Paraquat (1, 1'-dimethy-14, 4' dipyridium chloride: Gramoxon(r)) was first discovered in England in 1955. It has been widely distributed for use in Korea since 1970 as a pesticide and also often the cause of accidental intoxications. The authors would like to report the following case of paraquat intoxicatio in a 13 year old female child admitted via emergency room with complaints of epigastric pain, vomiting and hematuria of four days duration. On admission the data of laboratory evaluation were as follows: BUN/Cr 126/11.6 mg/dl; sGOT/sGPT 641/641 IU/L; total bilirubin/direct bilirubin 3.9/2.4 mg/dl; alkaline phosphatase 396.1 U/L; fecal occult blood test-positive; pH 7.428, pCO2 26.2 mmHg, pO2 131.4 mmHg, base excess -5.0 mmol/L on arterial blood gas analysis (ABGA). Gastroendoscopy revealed esophageal ulcers, and as symptoms of renal failure could not be relieved by hemodialysis, kidney biopsy was performed on the otherwise previously healthy child to establish the cause of renal failure. The result of biopsy revealed tubular necrosis with eosinophilic infiltrations. A more detailed retrograde probe of the child's past medical history evoked that the patient had ingested paraquat in a suicidal attempt. Supportive therapy and hemodialysis were continued thereafter, but the symptoms of renal failure could not be reversed, and the patient eventually died due to acute respiratory distress syndrome.

BACKGROUND: T. vaginalis is a pathogenic protozoa infecting genitourinary tract. Metronidazole is a drug of choice to treat T. vaginalis infection. However, because of appearance of metronidazole- resistant T. vaginalis, it is needed to develop an alternative drug. So, we evaluated the effects of various concentration of kalopanaxsaponin A against T. vaginalis. METHODS: The antiprotozoal effect of kalopanaxsaponin A on the growth and fine structure of T. vaginalis was examined by using trypan blue exclusion assay and electron microscopy. RESULTS: The viability test showed markedly decreased number of T. vaginalis, treated with increasing concentration of kalopanaxsaponin A. We evaluated the electron microscopic findings for antiprotozoan effects against T. vaginalis. SEM showed that in T. vaginalis treated with 4 microgram/mL for 1 hour, axostyle was shrinked and flagella began to disappear. With gradual increase of the concentration of kalopanaxsaponin A, destruction of cell membrane was getting more severe, and degenerative change was observed in T. vaginalis treated with 8 microgram/mL for 2 hours. TEM showed that in T. vaginalis treated with 4 microgram/mL for 2 hours, the vacuoles in cytoplasm were larger and hydrogenosomes were smaller than those in control group. The number of vacuole was increased, the nucleus was destroyed, the number of polyribosome and free ribosome was also decreased in trichomonads treated with kalopanaxsaponin A (8 microgram/mL), which indicated the occurrence of degenerative changes. CONCLUSION: These results indicated that kalopanaxsaponin A had the antiprotozoal effect on T. vaginalis by inhibition of cell multiplication as well as an impairment of protein synthesis.

PURPOSE: Prolonged urinary incontinence is one of the greatest concerns for patients undergoing radical prostatectomy. One of the possible causes for this urinary incontinence is a postoperative deficiency of the external striated urethral sphincter (EUS) complex and continence nerves. We evaluated the effect of posterior urethral reconstruction (PUR) in the early recovery of urinary continence after robotic-assisted radical prostatectomy. MATERIALS AND METHODS: Between January 2008 and March 2009 we performed robotic-assisted radical prostatectomy with PUR in 30 patients (PUR group) and without PUR in 30 patients (non-PUR group). We compared perioperative parameters and postoperative continence rates between the two groups. Continence was defined as no pads or one diaper per 24 hours and was assessed 1 month, 3 months, and 6 months after the procedure. RESULTS: Patients in the PUR group achieved better continence rates at 1 month (43% vs. 35%) and 3 months of follow-up (89% vs. 64%). At 6 months of follow-up, the continence rate was similar between the two groups (96% vs. 90%). No major complications were observed in the PUR group. However, 2 cases of anastomotic site leakage and 1 case of delayed bleeding were observed in the non-PUR group. CONCLUSIONS: Posterior urethral reconstruction appears to be an easy and reproducible technique in robotic-assisted radical prostatectomy. Our early experience demonstrates that PUR in robotic-assisted radical prostatectomy appears to confer early continence recovery and reduce intraoperative complications.

BACKGROUND: Cutaneous melanoma is the leading fatal illness arising in the skin. The clinical and pathological characteristics of malignant melanoma are quite different among races and countries. OBJECTIVE: The purpose of this study was to investigate the clinicopathologic behavior of malignant melanoma in Korea and define prognostic predictors. METHODS: From the 61 patients diagnosed with malignant melanoma at the Department of Dermatology of the Severance Hospital, Yonsei University College of Medicine over a 12 year period(1989-2001), we analyzed mean age at onset, gender, histologic subtypes, tumor thickness, primary tumor locations, and metastatic sites. Univariate analysis and multivariate analyses for survival, according to clinical and histologic tumor behavior, were performed by means of Cox proportional hazard model. Survival curves were plotted by Kaplan-Meier method. RESULTS: Fifty-eight primary cutaneous melanomas were identified and analyzed by both clinical behavior and histology. 1. The incidence of malignant melanoma has been rising at a fast rate in the Department of Dermatology, Yonsei University College of Medicine. 2. The male to female ratio was 1:1. Acral lentiginous melanoma was the most common type(56.9%) followed by nodular melanoma(19.0%), superficial spreading melanoma(12.1%), lentigo maligna melanoma(6.9%), and mucosal melanoma(5.1%) in this study. ALM(59 years) and SSM(53 years) developed in elderly persons, while NM(43 years) developed in younger persons. 3. Sole and nail bed were the favored sites in ALM. Trunk was the favored site in SSM. 4. Univariate and multivariate analyses for overall survival of melanoma revealed that male gender, lentigo maligna melanoma, thicker tumor(>or=4.0mm), advanced stage(III and IV) have the tendency to poorer prognosis with significant differences. CONCLUSION: Our study revealed acral lentiginous melanoma was the most predominant type of melanoma in Korea, which is similar result to other Asian countries'. No similar large series has been conducted to assess the prognostic factors of melanoma in Korea. Therefore, we propose that gender, histologic subtypes, tumor thickness, stages are the independent risk factors for poor prognosis. Further prospective studies are needed to assess the biologic behavior of malignant melanoma of which the incidence has been increasing in Korea.
