It is generally recognized that several chemical mediators are involved in tbe pathogenesis of sunbum; however, the exact mechanism is still to he resolved. Recently, prostaglandin has been found to be one of the inflammatory mediators in sunbum, particularly in the delayed erythema response and several investigators have shown that the nonsteroidal antiinflammatory drugs inhibit the in vivo synthesis of prostaglandin. On the assumption that the nonsteroidal antiinflammatory drugs might exert a beneficial effect on the sunbum through the antiprostaglandin effect, several authors have reported the effect of indomethacin on sunbum. This study was undertaken to evaluate the effect of topical indomethacin on the delayed erythema response induced by artificial sunlamp and sunlight by clinical and histopathological examination. Indomethacin(2. 5% ointment, 2. 5% solution, 5% solution) was applied immediately after 3 MED irradiation of artificial sunlamp to the shaved back skin of 6 healthy albino guinea pigs weighing 550-850gm and 9 human volunteers and the delayed erythema response was observed at 2, 4, 6, 12, 24 and 48 hours after irradiation respectively. Punch biopsies of the skin were performed on 6 guinea pigs at 6, 12, 24 a.nd 48 hours after irradiation and the histologic changes were observed. Four human volunters were exposed t,o 3 MED of sunlight and indomethacin preparations were applied immediately after irradiation. The delayed erythema response was observed at 2, 4, 6, 12, 24 and 48 hours postirradiation and in one volunteer, the skin was biopsied at 24 hour for histologi.c evaluation. The results were as follows: 1. Topical indomethacin in ointment or solution forms delayed and decreased the appearance and degree of erythema induced by sunlight and artificial sunlamp in both human and animal subjects. 2. Histologically, the number of sunbum cells at 24 hour in the epidermis of one human volunteer was decreased on indomethacin applied sites. The dermis showe6 no difference in histologic changes between control and indomethacin sitea. In animal study, however, no detectable difference in epidermal or dermal changes was observed between control and indomethacin applied sites. The autors confirmed that topical indometha,cin was effective in delaying and blanching of the delayed erythema of sunbum in guinea pigs as well as in human volunteers, though there was no difference in histologic changes between indomethacin and control sites in guinea pigs. The mechanism involvel on this aspect is remained to be resolved.

Aortic Aneurysm, Abdominal

PURPOSE: The ictal perfusion patterns of cerebellum and basal ganglia have not been systematically investigated in patients with temporal lobe epilepsy (TLE). Their ictal perfusion patterns were analyzed in relation with temporal lobe and frontal lobe hyperperfusion during TLE seizures using SPECT subtraction. MATERIALS AND METHODS: Thirty-three TLE patients had interictal and ictal SPECT, video-EEG monitoring, SPGR MRI, and SPECT subtraction with MRI co-registration. RESULTS: The vermian cerebellar hyperperfusion (CH) was observed in 26 patients (78.8%) and hemispheric CH in 25 (75.8%). Compared to the side of epileptogenic temporal lobe, there were seven ipsilateral hemispheric CH (28.0%), fifteen contralateral hemispheric CH (60.0%) and three bilateral hemispheric CH (12.0%). CH was more frequently observed in patients with additional frontal hyperperfusion (14/15, 93.3%) than in patients without frontal hyperperfusion (11/18, 61.1%). The basal ganglia hyperperfusion (BGH) was seen in 11 of the 15 patients with frontotemporal hyperperfusion (73.3%) and 11 of the 18 with temporal hyperperfusion only (61.1%). In 17 patients with unilateral BGH, contralateral CH to the BGH was observed in 14 (82.5%) and ipsilateral CH to BGH in 2 (11.8%) and bilateral CH in 1 (5.9%). CONCLUSION: The cerebellar hyperperfusion and basal ganglia hyperperfusion during seizures of TLE can be contralateral, ipsilateral or bilateral to the seizure focus. The presence of additional frontal or basal ganglia hyperperfusion was more frequently associated with contralateral hemispheric CH to their sides. However, temporal lobe hyperperfusion appears to be related with both ipsilateral and contralateral hemispheric CH.

We report a case of 64-year-old female patient who has had factitious skin lesions for 20 years. She complained formification sense and severe itching on her face. These symptoms were improved with squeezing and bleeding. There were scuare shaped ulcerated nodule on the right cheek and white depressed scar on the left cheek. She was treated with wet dressing and occlussive dressing, and skin lesions were nearly cleared within 3 weeks, but new lesion appeared. Pimozide 2mg #1 p.o were given under the diagnosis of delusion of parasitosis from June, 1984. Her symptoms were improved without recurrence till now. Treatment with pimozide in monosymptomatic hypochondriacal syndrome is discussed.

Bezoyl peroxide, a powerful oxidizing agent, has been uaed topically in the treatment of acne vulgaris as a cream or lotion and has been shown to he effective for this codition. In 1972 Fulton emphaaized the importance of the vehicles used to obtain. maximum potential of benzoyl peroxide and for this, the gel formulation has been examined in many clinical trials. The present study was undertaken to evaluate the therapeutic effect of Fanoxyl 2.5, a 2.5% . benzayl peraxide gel, in patients with acne vulgaris. A total of 31 patients entered this study at the Departrnent of Dermatology, Jeoul National University Hospital rluring 3 rnanths period, from Decemher, 1978 through February, 1979, All patienta were instructed to apply Fanoxyl 2.5' on their affected areas once or twice a day and the nurnber of lesions on two or three t fixed areas were counted before and onee weekly after initation of the treatment. The reaults observed in the 3I patients were as follaws; 1. The percentage decrease in total nurnber of lesions in 4 weeks after treatment was 56.9%. 2. The authors could follow up for 6 weeks in 6 cases. In 6 case, the mean percentage in total number of lesions in 6 weeks after treatment was 81.7%. 3. Clesed and open eomedones were gradually eliminated; and their numbers were decreased in 4 weeks after treatment by 46.5% and 56.8% respeetiveIy. The papules were rapidly eliminated and their numbers were decreased in 4 weeka, after treatment by 79.8%. 4. Although most patients felt a mild burning sensation and tightness at the begining of the treatment, only a minority of the patients complained of discomfort due to pain(l case), erytherna(l case), tightness(2 cases),burning sensation (1 case), scaling(1 case). But all were tolerable without taking any specific measures or discontinuance of application. In one case, contact dermatitis developed after 4 weeks treatment. The authors concluded through this experiment that Panoxyl 2.5' (2.5% benzoyl peroxide gel) is a very effective local therapeutic agent in the treatment of acne vulgaris patients.

Cloeortolone (9-a-chloro-6-a fluoro-11-B 21 digydroxy-16 methyl preganl,4-diene) is a newly synthesized corticonsteroid which has been found to have potent antinflammatory action and good tolerance through animal experiment. Several investigators reported its therapeutic affect in various dermatoses by topical application. The present was undertaken to evaluate the therapeutic effect of 0.1% clocortolone cream (Purantix-Sandoz) in patients with eczematous dermatoses and with psoriasis and to compare its effect with that of I% hydrocortisone. Eleven patients with contact dermatitis, 10 with psoriasis entered this study durtin the period of 6 months from January to june, 1977 at the Department of Dermatology, Seoul National University Hospital. All patients were instructed to apply 0.1% Clocortolone cream on one side of their lesion and 1%hydrocortisone cream on the opposite site for two weeks. After wo weeks' period of observation the status of the lesion was evaluated clinically and the tesults were as follows. 1. Ninety one percent of patiens with contact dermatitis, 70% of atopic dermatitis, 60% of nenrodermatitis, 67% of nummular eczema and 60% of psoriasis responded very effectively or moderately effectively. The therapeutic responses were generally similar to that of 1% hydrocortisone. 2. During the ovservation period, there was no systemic of local side effect of 0.1% Clocortolone cream.

Acne Vulgaris*

Lichen striatus is an uncommon nonspecific inflammatory cutaneous disease of unknown etiology occuring as unilateral and linear distribution on extremities and healing spontaneously within a few months to a year. Clinically it is composed of small licbenoid papules which tend to be grouped and coalesced to form either a continuous or an interrupted hypopigmented band and is not usually accompanied by any subjective symptoms. The principal histologic features are an infiltrate composed of lymphocytes and histiocytes around papillary vessels and usually also around, some of the deeper vessels and skin appendages and consequent secondary changes of the epidermis. We present the results of clinical and histopathologic observation in 19 patients with lichen striatus observed at Department of Dermatology, National Medical Center and Seoul National University Hospital during 4 years period from l972 to 1976 which would be the first recorded report on this rare disease in Korea. 1. Clinieal Observation.' Among the 19 patients, 10 were female and 9 were male; 15 were under 10 years of age and 4 were over 10 years of age. Duration of the eruption varied from 1 week to 4 years and average duration was 9.6 months at the time of the first visit. It was unilateral in all cases and affected the upper extremities in 9 and the lower extremities in 8 instances. The eruption extended onto the upper part of the trunk in 2 cases. Only 3 patients had a history of mild intermittent itching sensation. Characteristically, the eruption consisted of grouped, linear, slightly scaling flat polygonal papules with varying degrees of hypopigmentation, extending at least onethird of the length of an extremity. . Histopathologic observation: Skin biopsy was performed in 13 cases. The epiderrnal changes consist of mild diffuse hyperkeratosis (13 cases), focal parakeratosis (5 cases), varying degree of atrophy of malpighian layer (7 cases), mild acanthosis (2 cases), intercellular and intracellular edema (8 cases), exocytosih of lymphocytes (7 cases), focal basal cell disruption (11 cases), and dyskeratotic cells (colloid body) (2 cases). Dermal changes include mild to moderate perivaacular lymphocytic and histiocytic infiltrate rnostly on the level of papillary dermis. Also, there was chronic infIammatory cell infiltrate around hair follicle and sweat glands and ducts in 7 cases respectively, which seems to be peculiar in this disease. Overall histologic findings in our cases are generally consistent with those of the primary phase of the so-called lichenoid tissue reaction of Pinkus, The possible pathogenetic mechanism of the linear eruption and immunobiologic interpretation of the lichenoid tissue reaction were literally reviewed.
