BACKGROUND: Pruritus, which is a frequent accompanying symptom of dermatological diseases, is also common during pregnancy, either localized or generalized. It may be related to specific dermatoses of pregnancy. OBJECTIVE: A clinical study was performed to know the exact nature of pruritus in pregnancy. METHODS: Subjects with systemic diseases, or laboratory abnormalities were excluded. People who have had pruritic dermatologic diseases before pregnancy were also excluded. One hundred and fifty five pregnant women were interviewed with physical examinations and followed up to the date of delivery. Pruritus was graded. RESULTS: Pruritus was present in 31.6%. Most affected subjects had mild or moderate severity. The abdomen was the most common site. There was a tendency for the duration of itching to increase with the duration of pregnancy. CONCLUSION: Conclusion: These findings may provide basic and useful data on pruritus during pregnancy.

There have been several reports in the literature of coexistent psoriasis and bullous pemphigoid. In most cases, the bullous pemphigoid lesions have been considered to be induced by antipsoriatic treatments. We describe a patient with psoriasis in whom bullous pemphigoid developed during psoriasis treatment, but the exact etiologic factor was not identified. Recently, some reports have suggested that an immunologic or biochemical association between the two diseases plays a role in the pathogenesis.

Persistent light reaction, actinic reticuloid, photosensitive eczema are three chronic photodermatoses with a feature of clinical, histological, and photobiologieal characteristics in common. These conditions were given the name of chronic persistent photosensitivity. Chronic persistent photosensitivity with the feature of photosensitive eczema developed in a 68-year-old male patient who had experienced persisited dermatitis. On phototesting the patient showed extremely severe photosensitivity to the short wave UVB. A skin biopsy showed microscopic finding of eczematous dermatitis.

BACKGROUND: Recentliy copper vapor laser(CVL) has been applied with encouraging results in the treatment of port wine stain. The CVL emits yellow light(578nm) in a sequence of about 10,000 to 15,000 pulses/second(10-15kHz) with a pulse duration of 15-50 cases. One of the basic methods of evaluationg the effects of laser lights is to study histologic changes after laser irradiation. OBJECTIVE: The effects of power output and energy density on the histologic change of guinea pig skin following CVL irradiation was evaluted to suggest a way of deciding parameters of CVL to achieve the best clinical results. METHODS: After setting the power output for one of 0.8W, 1.6W and 2.4W, the laser was irradiated with an energy density of 10, 12, 14, 16, 18, 20J/cm. A biopsy was done 15 minutes after irradiation and the biopsy specimens was stained with H&E and NBTC histocberr ical method. RESULTS: 1. At the power of 0.8W, specimens irradiated with an energy density above 14J/cm showed diffuse nonspecific coagulation necrosis of the epidermis and upper dermis. 2. At the power of 1.6W, specimens irradiated with energy density of 14, 16J/cm showed coagulation necrosis of dermal vessel and perivascular collagen. With energe density of 18, 20J/cm, diffuse nonspecific coagulat,ion necrosis of epidermis and upper dermis were observed. 3. At the power of 2.4W, specimens irradiated with an anergy density of 12, 14, 16, 18J/cm showed coagulation necrosis of the dermal vessel and perivascular collagen. With an energy density of 20J/cm, diffuse nonspecific coagulation necrosis of the epidermis and upper dermis was observed. CONCLUSIONS : With the above results it was found that t,he higher power output of CVL enlarged the range of energy density confining thermal damage to the dermal v-ssels and perivascular collagen. Additionally the higher power raised the upper limit of energy density with which t,he epidermis was viable.
