Hydroa Vacciniforme is a rare, light sensitive dermatitis characterized by discrete vesicles followed by varioliform scar formation, which was first described by Bazin on 1862. We have expe"ienced three cases of hydroa vacciniforme in childhood. The first case was a 6-year-old boy who had discrete vesicles, crusts and pitting scars on forehead, both cheeks, ears and dorsum of the hands in symmetrical distribution with itching sensation, which had used to recur in every summer since last three years ago. Histologic section of a primary lesion showed necrosis and severe edema in the epidermis and adjacent dermis with the dermal inflammatory cell infiltration. The second case was a 10-year-old girl who had discrete vesicles, crusts, erosive and depigmented patch and scars on face, lip, dorsum of the hand and forearm with itching sensation, which had also developed on last spring. The third case was a 7-year-old boy who had vesiclee, erosive patch, crusts and pitting scars on face, Iower lip, both dorsum of the hand and forearm with itching sensation, which had recurred in every summer since last two years ago, On urine examination, porphyrin, was negative in all three cases. Diagnosis was established by clinical characteristics and laboratory findings and histological pictures. Symptomatic treatment was done in all three cases. The literatures were briefly reviewed.

The purpose of this study was to investigate setting and thermal expansion of dental soldering investments. In order to compare expansion rates and to investigate the effect of water/powder ratio on expansion, setting and thermal expansion of four dental soldering investments were measured under three different water/powder ratio conditions: standard, 20% decreased and 20% increased. Setting expansion of investments was measured by use of dialgauge method. Each measurement was started two minutes later from the beginning of spatulation and recorded every one minute for one hour. Thermal expansion of cylindrical test specimens, 10mm diameter, 50mm length, was recorded in a Thermodilatometer at heating rate of 10degrees C per minute from 25degrees C to 700degrees C. The results of this study were obtained as follows: 1. Setting expansion rates under the standard water/power ratio condition were 0.198% in Speed-E, 0.090% in Deguvest, 0.080% in CM and Hi-temp. Setting expansion of Speed-E was significantly different from those of CM, Deguvest and Hi-temp, and setting expansion of Deguvest was significantly different from those of CM and Hi-temp(p<.05). 2. Under the decreased water/powder ratio condition, there was significant increase in setting expansion of 4 dental soldering investments(p<.05). 3. There were no significant differences in setting expansions of investments except Hi-temp between standard and increased water/powder ratio condition(p<.05). 4. Thermal expansion rates under the standard water/powder ratio condition were 1.923% in Deguvest, 1.629% in Speed-E, 1.619% in Hi-temp and 1.580% in CM. No significant difference in thermal expansions under the standard water/powder ratio condition existed only between Speed-E and Hi-temp(p<.05). 5. Under the decreased water/powder ratio condition, there was significant increase in thermal expansion of CM and Deguvest but decrease in thermal expansion of Speed-E(p<.05). 6. Under the increased water/powder ratio condition, there was significant decrease in thermal expansion of CM, Deguvest and Speed-E but decrease in thermal expansion of Hi-temp(p<.05).

PURPOSE: The purpose of this study was to provide basic data on preventive child abuse program development. METHOD: Data were collected on 105 high-risk families of child abuse intervention was obtained from their main child rearer who raised the child under 18 years, olds during 10 months period from May, 2000 to March 2001. RESULT: The results were as follows : 1. Child abuse occurred in the subject's home, in the case of mild child abuse, 'throwing an object at the child' had the highest percentage 39.1%, in severe child abuse, 'rod, stick, belt, broom beating or using a variety of objects such as' had the highest percentage 49.5%, and in very severe child abuse, 'hospitalized by belting' had the highest percentage 3.8%. 2. The degree of child abuse potential showed high risk child abuse score with a mean of 213.3. The degree of beliefs in corporal punishment showed that subjects perceived corporal punishment of children positively with a mean of 32.2. 3. With respect to the child abuse potential, there were significant correlations with the subjects' age (r=.294, p=.002), education level (r=-.442, p=.000), and family income (r=-.355, p=.000). CONCLUSION: From this study not only child abuse occurrence but also child abuse potential were severely increased in poor livelihood families. Therefore to the high risk group, individual preventive approach must be applied.

OBJECTIVES: To develop reliable tools for measuring communication skills in schizophrenia, the present study proposed the concept of communication intelligence, consisting of conversational competence, emotional competence, and empathic competence, and explored its neurobiological underpinnings using regional gray matter volume with healthy people. METHODS: Communicative intelligence scores were obtained from 126 healthy young participants. Correlation analyses between regional volume distributions and communication intelligence subcomponents were conducted using voxel-based morphometry of structural MRI. RESULTS: The significant positive correlations between the regional gray matter volumes with conversational competence were found mainly at the ventromedial frontal gyrus while the negative correlations between the bilateral middle frontal gyrus. With emotional competence, the volume of right superior temporal gyrus was positively and that of bilateral insula was negatively correlated. With empathic competence, the volume of the left middle frontal gyrus was positively and that of the insula was negatively correlated. CONCLUSION: Each of the subcomponents of communicative intelligence scores showed distinctive neurobiological underpinnings. The regions for the subcomponents, which constitute a common network for social cognition and emotion, are highly associated with the regions of the schizophrenia pathology. In conclusion, communicative intelligence scales have neurobiological basis to evaluate social skills of patients with schizophrenia.

PURPOSE: The purpose of the study was to identify the adequacy of enteral feeding, and the reason and prevalence of under-nutrition, and to determine the relationships between caloric intake and resulting nutritional parameters among neurosurgical intensive care unit (ICU) patients. METHODS: The participants for this descriptive study were 47 neurosurgical ICU patients who had enteral feeding initiated after ICU admission. Data were collected from the initial day of enteral feeding for 7 days. Data related to enteral feeding, feeding interruptions or delay, prealbumin, and transferrin were collected. RESULTS: The mean age of the participants was 56.62 years. Twenty-six patients did not receive their feeding formula more than once during 7 days, and 11 had interruptions more than 6 times. The mean number of feeding interruptions was 3.23 (SD= 4.47). On the average, only 76.44% of the estimated energy requirement was provided by enteral feeding to the patients. The frequency of underfeeding was 52.17% with respect to enteral feeding. The most frequent reason for the feeding interruption was observation before and after intubation and extubation, which was unavoidable. The next most common reason was gastrointestinal bleeding, mostly due to old clots or trace, followed by residual volume less than 100 mL. Changes in prealbumin and transferrin levels for 7 days between the underfed and adequately fed groups were not statistically significant. CONCLUSION: The management of enteral feeding by nurses was overprotective because of the unpredictable nature of ICU patients in terms of their underlying disease process. The management of feeding intolerance needs to be evidence-based and nurses must consistently follow the protocol that has been supported as a useful measure.

We report two cases of supratentorial gangliocytomas mimicking an extra-axial tumor. MR imaging indicated that the tumors were extra-axial, and meningiomas were thus initially diagnosed. Relative to gray matter, the tumors were hypointense on T1-weighted images and hyperintense on T2-weighted images. On contrast-enhanced T1-weighted images, homogeneous enhancement was observed, while CT scanning revealed calcification in one of the two cases.

PURPOSE: Liquid beta emitter filled in angioplasty balloon could be used to perform endovascular balloon brachytherapy to prevent coronary artery restenosis. We investigated the dosimetry for Re-188-DTPA liquid-filled balloon and medical internal radiation dosimetry in case of balloon leakage. MATERIALS AND METHODS: We estimated radiation dose from an angioplasty balloon (20 mm lengfh, 3 mm diameter cylinder) to the adjacent vessel wall using Monte Carlo EGS4 code. We obtained time-activity curves of kidneys in normal dog and calculated Tmax, T1/2. Using MIRDOSE3 program, we estimated absorbed doses to the major organs (kidneys, bladder) and the whole body when we assumed that balloon leaked all the isotope contained. RESULTS: The radiation dose was 17.5 Gy at the balloon surface when we applied 3,700 MBq/ml of Re-188 for 100 seconds. Fifty percent of the energy deposited within 1 mm from the balloon surface. The estimated internal dose to the whole body was 0.005 mGy/MBq and 18.5 mGy for the spillage of 3,700 MBq of Re-188. CONCLUSION: We suggest that Re-188-DTPA can be used for endovascular balloon brachytherapy to inhibit coronary artery restenosis after angioplasty with tolerable whole body radiation dose in case of balloon rupture.

The recent prevalence of syphilis has known to be increased progressively throughout the world, since middle of 1950. In Korea, current trend of increased syphilic infection has became a major public health problem. The authors selected sero-positive patients, among the outpaients of department of dermatology, urology, OB & GY, and physical examination, and performed statistical analysis of this sero-positive patients. Results are as following; 1) Of the 2,007 patients taken physical examination, 30 patient(1.49%) were reactive to VDRL. 2) 0.71% of the total out patients of the dermatologic dcpartment were sero-positive. Annual ratio of the syphilitic patient were increased progressively. 3) Ratio of the syphilitic patients to the total outpatients of OB & GY department was 0.55% and somewhat increased since 1976. 4) In the age distribution, the third decade shared 51.8% of the total sero-positive patients 5) In the sexual ratio. male:female=l: l. 62 in the total sero-positive patients. (male:female=l: 1.06 in the dermatologic department.) 6) In the stage distribution, latent syphilis patients were 59.14% of the total syphilitic patients.
