Hailey-Hailey disease is a rare hereditary dermatosis that begins in the 2nd or 3rd decade of life. The skin lesion is characterized by a localized, recurrent eruption of small vesicles on an erythematous base. It courses remissions and exacerbations. It seldom begins in early childhood, and main treatment modalities are conservative ones. We report a case of Hailey-Hailey disease that began on a 7-month old infant and improved by surgical treatment. In according to review of the previous reports, it is probably the earliest onset age and it is may be the first case which was treated with surgery in Korea.

BACKGROUND: Evening primrose oil(EPO) is a rich source of cis-linoleic acid and gammalinolenic acid(GLA) and has been used as a therapeutic agent in various skin diseases such as atopic dermatitis. OBJECTIVE: The purpose of this study was to evaluate the suppressive effect of EPO on murine contact sensitivity. METHODS: BALB/c mice were divided into 3 groups, positive control, experimental and negative control groups: the positive control group represents a group of mice which were sensitized and challenged with DNFB, the experimental group represents EPO-pretreated positive control group and the negative control group represents a group of mice which were challenged only. The changes of ear thickness were measured, and H & E staining and immunohistochemical staining for ICAM-1 expression of ear skin were performed to evaluate the histological changes of each group. RESULTS: The Pretreatment of mice with EPO resulted in suppression of contact sensitivity by more than 82%. On H & E staining, only a mild inflammatory reaction was observed in the dermis. Also ICAM-1 expression of keratinocytes, the intensity of the staining was significantly decreased in the experimental group compared with positive group. CONCLUSIONS: Our study indicates that EPO was able to suppress the induction of contact sensitivity.

The lack of specificity of an abnormal findings visualized on a conventional radiocolloid liver imaging remains a significant limitation of the examination. The purpose of this investigation is to clarify an equivocal abnormal finding visualized on a conventional liver and spleen imaging by using combination of scintiangiography and histogram as a quantiative assessment. Histo-analysis of peak colloidal distribution in the liver and spleen was undertaken as a complement of conventional liver imaging. The following useful patterns was emerged: 1. In hepatitis, the splenic uptake was slightly higher than in normal group. This change was usually not recognized in conventional imaging. 2. In liver cirrhosis, the liver uptake was markedly low whilst splenic uptake was very high, resulting in splenic shift and very low liver-spleen uptake ratio. 3. In hepatoma, the liver uptake was not definitely changed but splenic uptake was considerably high, so that the liver-spleen uptake ratio was very low. 4. In liver metastasis, both liver and splenic uptakes were within normallimits and the liver-spleen uptake ratio was not changed.

Early detection of neoplastic disese and metastatic spred is very important. Carcinoma of the breast is knownto readily metastasize to the bone. The use of Tc-99m-phophate as bone imaging agent has been shown to demonstrate early evidence of bone metastasis well before radiographic evidence is visualized and as thus become a very usefultechnique for establishing and monitoring the bony metastatic element of breast cancer. In this study, serial boneimaging studies were performed to monitor the management of 84 breast cancer patients before and after mastectomyand biopsy. We attempted to analyse bone scans of breast cancer and to correlated the scan findings with theclinical stage, status of lymphnodes, distanat metastasis, bone pain, and laboratory datas. The following useful patterns were emerged: 1. Postive bone scan rate was definitely higher in clinical stage III and IV (42, 57%) thatin stage I and II(4, 18%) in initital studies. However, no correlation between positive bone scan rate andclinical stage was found in follow up studies. 2. Positive bone scan rate was high in both groups with locallyadvanced tumor(T3 & T4) and distant metastasis. 3. No correlation between postive bone scan and status oflymphnode involvement was noted. 4. Positive bone scan rate was also very high in patients with bone pain andabnomral laboratory data.

Sclerosing lymphangitis of the penis occurs as a skin-colored or dusty red, cord-like thickening of tissue at the corona or within the coronal sulcus. The thickened, elongated lesion is firm and relatively nontender. The cause is unknown: because it occurs primarily in those who are sexually very active, however, it is likely that chronic trauma plays an important etiologic role. We experienced a case of pathologically proven sclerosing lymphangitis in a 31 year-old man. Ultrasonographic finding showed circumferential cord like hypoechoic band with irregular, but well demarcated margin.

PURPOSE: To evaluate MR imaging findings of degenerating parenchymal neurocysticercosis and to determine the characteristics which distinguish it from other brain diseases. METHODS: MR imagings of 19 patients (56 lesions)of degenerating parenchymal neurocysticercosis were retrospectively evaluated, focusing on the size and locationof lesions, signal intensity patterns of cyst fluid and wall, the extent of the surrounding edema and features of contrast enhancement. RESULTS: Degenerating parenchymal neurocysticercosis was located in gray or subcortical white matter in 89.3% of 56 lesions(50/56); most of these (98.2%) were smaller than 2cm in diameter. Cyst fluidsignal was hyperintense relative to CSF on T1 and proton density weighted images (92.9%). A hypointense signal rimof the cyst wall was noted in the lesions on proton density (92.9%) and T2 weighted (98.2%) images. Surrounding edema was mostly mild. Peripheral rim enhancement was noted in all lesions, and this was frequently irregular and lobulated (67.9%) with a focal defect in the enhancing rim (41.1%). CONCLUSION: Findings which could be helpfulin distinguishing degenerating parencymal neurocysticerosis from other brain diseases are as follows : small, superficial lesions ; hyperintense signal of the cyst fluid on T1 and proton density weighted images ; hypointense signal of the cyst wall on proton density and T2 weighted images ; relatively mild extent of surrounding edema,and peripheral rim enhancement which is frequently irregular and lobulated with a focal defect in the enhancingrim.

PURPOSE: This study was to report our experience of the brief survey for teaching journal writing by medical students in a clinical curriculum of family medicine. METHODS: Brief surveys performed by medical students in clinical clerkship of department of family medicine from 1998 to 2000. Medical students determined theme without rein for brief surveys. Lecture about meaning and process of survey was given for sufficient understanding of students, and then surveys were conducted. The subjects of survey were outpatients, nursing person, medical students, nursing students, and other general persons. The subjects of theme were classified to 17 chapters 7 components by international classification of primary care(ICPC). RESULTS: In analysis of brief surveys according to ICPC, the reasons for surveys by components were diagnostic, screening prevention(89.0%), treatment, procedures, medication(5.7%), symptoms, complaints(5.3%). By chapters, there were social(64.6%), psychological(12.6%), metabolic and endocrine(6.5%). Among social problems, there were other social problem(35.4%), health care system/access(20.9%), problem with education(13.9%), relation problems partner(12.7%). Majority of medical students had affirmative response for survey conduction. In conclusion, our finding suggest that teaching journal writing as brief survey seems to be useful in understanding of journal writing of medical students.

PURPOSE: In this study, we report our initial experience with robot-assisted laparoscopic partial cystectomy (RLPC) in urachal diseases. MATERIALS AND METHODS: Two men and two women with a mean age of 51.5+/-9.3 years underwent RLPC between June 2009 and December 2009. In each case, a single surgeon using the da Vinci-S robotic system (Intuitive Surgical, Sunnyvale, CA, USA) used a transperitoneal approach with a 0 degrees robotic camera. After careful observation of the intravesical portion of the mass, the mass was excised by use of monopolar scissors circumferentially. The bladder was closed in two layers with watertight running sutures made with 2-0 Vicryl. RESULTS: The mean operative time was 198 minutes (range, 130-260 minutes), the mean console time was 111 minutes (range, 70-150 minutes), and the mean estimated blood loss was 155 ml. The urethral catheter was removed on postoperative day 7 after a normal cystogram, and the surgical drain was removed on postoperative day 2.5 (range, 2-3 days). The mean hospital stay was 6 days (range, 4-7 days). There were no major complications. The pathology report revealed that one patient had a urachal cystadenoma, two patients had a urachal cyst, and one patient had a patent urachus. CONCLUSIONS: Our initial experience with RLPC for benign urachal disease is that it is a safe and feasible treatment modality. However, more cases are required to confirm the efficacy of RLPC.
