We report a case of giant M llerian duct cyst in a 6 month-old-boy with urinary tract infection. A mass displacing the bladder and prostatic urethra anteriorly was found on the voiding cystourethrogram, and it was a oval shaped retrovesical anechoic cyst on the abdominal ultrasonogram. On MRi, it was a tear-drop shaped cyst of isosignal intensity with a projection toward the prostatic urethra and located in the midline of vesicorectal space. Grossly, the cyst had communication with prostatic urethra and both vas deferenses were drained to the cyst. Pathologically it was confirmed as a M~'llerrian duct cyst lined with squamous epithelium.

Fifty-one consecutive 186 patients with aneurysmal subarachnoid hemorrhage were treated from the day of admission with nimodipine which was given first as an IV infusion at 30ug/kg/hr for 1 week and then orally in a dose of 360mg/day for 2 weeks and compared with 135 patients which were treated without nimodipine for the past 2 years. A comparision based on clinical and radiological variables influencing both the coruse and the outcome of the disease showed no significant difference between the nimodipine treated group and the control group except the delayed timing of surgery in the control group. There was no significant difference in the outcome between the nimodipine treated patients and the patients treated without nimodipine, however in Hung & Hess grade IV patients nimodipine treatment was associated with a significantly better outcome. Nimodipine treatment reduced the occurrence of delayed ischemic deficts(DID) in grade III, IV patients. Significant improvement in the outcome occurred in the nimodipine treated patients with subarachnoid hemorrhage of large amount(Fisher classification III).

The pinching motion is thought to be one of fundamental hand functions, the power of which has been quantified by measuring it isometrically with variously devised pinch-meters. The present authors describe the investigations on the pinching power of 350 healthy persons, 200 male and 150 female Koreans, by the use of Preston Pinch Gauge. Six kinds of pinch were chosen: (1) thumb index finger tip pinch (1-2TP), (2) thumb-middle finger tip pinch (1-3TP), (3) thumb-index finger pulp pinch (1-2PP), (4) thumb-middle finger pulp pinch (1-3PP), (5) thumb-index-middle finger pulp pinch (3PP), (6) key pinch (KP), which were classified again into 19 kinds according to the shape of thumb, index, middle, or other fingers during each pinch. We describe those as principal type, hyperextension-flexion type, hyperextension type and other type into four. It should be justified to calculate the mean normal value of principal type pinching power in Korean. Principal type of pinch involves 1-2TP, 1-3TP, 1-2PP, 1-3PP, 3PP and KP, as to Hyperextension type of 1-2PP, 1-3PP, 3PP and KP. Other type of pinch involving 1-2TP, 1-3TP, 1-2PP, 1-3PP, 3PP and KP is different from Principal type simply because of the shape of nonjoining fingers during pinch. Generally, the pinching power of Principal type was clearly highest among the four types except for pulp pinches.

STATEMENT OF PROBLEM: Recently, resin cements have become more widely used and have been accepted as prominent luting cements. Current resin cements exhibit less microleakage than conventional luting cements. However, the constant contact with water and exposure to occlusal forces increase microleakage even in resin cements inevitably. Most bonding resins have been modified to contain a hydrophilic resin such as 2-hydroxyethylmethacrylate (HEMA) to overcome some of the problems associated with the hydrophobic nature of bonding resins. By virtue of these modifications, bonding resins absorb a significant amount of water, and there may also be significant stresses at bonding interfaces, which may adversely affect the longevity of restorations. Therefore the reinforcement of water stability of resin cement is indispensable in future study. PURPOSE: This study was conducted to examine the influence of water retention on microleakage of two resin cements over the period of 6 months. MATERIALS AND METHODS: 32 ex acted human teeth were used to test the microleakage of a single full veneer crown. Two resin cements with different components and adhesive properties - Panavia F (Kuraray Co., Osaka, Japan) and Super-Bond C&B (Sun Medical Co., Kyoto, Japan)- were investigated. The storage medium was the physiological saline solution changed every week for 1 month, 3 months, and 6 months. One group was tested after storage for 1 day. At the end of the each storage period, all specimens were exposed to thermocycling from 5.C to 55.C of 500 cycles and chewing simulation of 50,000 cycles, and then stained with 50% silver nitrate solution. The linear penetration of microleakage was measured using a stereoscopic microscope at x 40 magnification and a digital traveling micrometer with an accuracy of +/-3 um. Values were analyzed using two-way ANOVA test, Duncan's multiple range tests (DMRT). RESULTS: Statistically significant difference of microleakage was shown in the 3-month group compared with the 1-day or 1-month group in bot systems (p<0.05) and there were statistically significant differences in microleakage between the 3-month group and the 6-month group in both systems (p<0.05). The two systems showed different tendency in the course of increased microleakage during 3 months. In Panavia F, microleakage increased slowly throughout the periods. In Super-Bond C&B, there was no significant increase of microleakage for 1 month, but there was statistically significant increase of microleakage for the next 2 months. For the mean microleakage for each period, in the 3-month group, microleakage of Super-Bond C&B was significantly greater than that of Panavia F. On the other hand, in the 6-month group, microleakage of Panavia F was significantly greater than that of Super-Bond C&B (p<0.05). CONCLUSION: Within the limitation of this study, water retention of two different bonding systems influence microleakage of resin cements. Further studies with the longer observation periods in viro are required in order to investigate water stabilty and the bonding durability of the resin cement.

Granuloma annulare is a common, benign, inflamatory, usually self-limited dermatosis. Disseminated perforating granuloma annulare is a rare variant of granuloma annulare. A 23-month-old female patient had asymptomatic, multiple umbilicated papules on the face, limbs including palms and soles, buttock and trunk for about 5 months. The new lesions have developed with mild fever or symptoms of upper respiratory infection. Histopathological examination revealed transepidermal elimination of mucinous degenerated collagen fibers and surrounding palisading lymphohistiocytic granuloma. After she was treated with prednisolone and antibiotics, the lesions slightly resolved, but thereafter, new lesions have developed frequently with mild fever. We herein reported a rare case of disseminated perforating granuloma annulare in the youngest patient yet reported.

Nevoid basal cell carcinoma syndrome (NBCC syndrome) is a very rare autosomal dominant dermatopathy characterized by a primary triad with variable secondary anomalies. The chief features include nevoid basal cell carcinomas, one or more skeletal anomalies, and multiple odontogenic keratocysts of the jaw. We report a case of NBCC syndrome in a 43-year old male who had multiple nevoid basal cell carcinomas on the retroauricular area, face, chest wall, and back, which have been present since childhood. Skull x-rays revealed relatively well-circumscribed cystic, radiolucent lesions on bilateral rami of both upper and lower jaws, calcification of the falx cerebri, agenesis of the right coronoid process, and a bifid chin. The cystic lesions were histologically confirmed as keratocysts.

Topical immunotherapy with diphenylcyclopropenone(DPCP) has been used for the treatment of alopecia areata. Due to the therapeutic principle of producing a contact eczema, itching, erythema and scaling are inevitable or even desired side effects. However, erythema multiforme-like reactions following topical DPCP treatment have been rarely reported with an estimated incidence of 1.2%. We present herein a case of Stevens-Johnson syndrome, the severe form of erythema multiforme as a side effect of topical DPCP. A 57-year old male patient visited us for the treatment of alopecia totalis. After sensitization with 0.2% DPCP in acetone, we applied DPCP on the scalp once a week for three weeks. Following the 3rd challenge of DPCP, iris-shaped lesions, erosions, vesicles, and bullae developed with fever. Also, he had vesicles and erosions in the oral cavity. The patient was treated with systemic antibiotics, steroids, and antihistamines. The cutaneous lesions were cleared with hyperpigmentation, and pronounced hair regrowth was observed.
