A nonivasive dermal ivestigation can be achieved using low intensity laser scanning of skin by measuring of light absorption and its reflection by different layers of derma. 52 otherwise healthy volunteers aged from 19 to 23 years old whose skin was intact enrolled the investigation. The following sites of skin surface were investigated: head, face, chest, back, extensive and flexoral surfaces of upper and lower extremities (12 sites). An analogous study was performed on 32 children aged from 5 to 14 years old. It was found that reflections at 11 sites of skin (exluding head) of each enrollee had the same intensity. These parameters of skin sites directly correlated with laser radiation energy. An analysis of reflection-laser radiation correlation led us to conclusion that superficial layer of skin, epydermidis, has the highest reflections capability. The deeper layers have a lower reflection capability. The same correlation was true for children which is associated with well formed protective properties of skin to harmful exogenous light energy.

Over the last 20-30 years more than 350 oilrigs have been installed in the sea outside the western coast of Norway. Enormous values from recovery of oil and gas have been created. A whole industry has developed both on shore and offshore. Among the workers in these industries skin problems are the most frequent complaints. The main group of workers for notification as occupational skin disease is the surface-coaters or spraypainters who have developed type IV allergy to epoxy. Details from our first 20 epoxy allergic workers will be reviewed. Figures are cumulating that seem to show that seem to show that from l-3% of the about 3000 surface-coaters may develop allergy to epoxy. If they do so, they are unable to continue their profession. Another frequent cause of contact dermatitis on the oilrigs is Oil Based Mud (OBM). Contact with the alkaline OBM causes cumulative irritative contact dermatitis among rough-necks when drilling is performed to 2000 m below

to evaluate the efficacy of the combination of cyclosporin and UVAB radiation in the treatment of severe atopic dermatitis in adults. The study population consisted of 20 adults, ranging in age from 23 to 59 years. All patients fulfilled the diagnostic criteria of Hanifin and Rajka for atopic dermatitis. Cyclosporin was administered for 3 months according to the following protocol: 5 mg/kg/day for first month, 4 mgkglday for second month and 3 mg/kg/day for the third month. UVAB treatment was undertaken at the first month and a half of cyclosporin therapy. The clinical response was evaluated every 2 weeks according to the SCORAD method. Treatment was well tolerated by all patients. No substantial side effects were noted. Six weeks from the start of treatment, all patients showed a satisfactory but not complete response to the treatment. After 3 months the response was complete in almost all patients. This combined therapy was found to be effective in the treatment of severe atopic dermatitis in adults. The protocol used was found to avoid the most common side effects of treatment with cyclosporin and UVAB separately.

Several recent reports have suggested that cyclosporin is effective in the treatment of atopic dermatitis, but long term use of this drug is not without its side effects. Another effective and relatively safe method of treating of atopic dermatitis is UV radiation. The combination of UVA and UVB has been shown to be more effective than either band alone. However UV cannot be used in the acute stages. The aim of the present study was

We describe a case of a 85-year-old woman, showing a nodular lesion, protruding on the skin, located on the abdominal wall. The lesion had been present for at least 7 years. The nodule, partly ulcered, was excised (excisional area 8 x 6 cm; maximum diameter of the lesion: 5 cm). Histology revealed a dermal-hypodermic lesion, having the features of a mixed eccrine tumor. Adenoid cystic aspects, with infiltrating attitude, confirmed the eccrine malignant nature. Nevertheless other figures, cylindroma-like and spiradenomalike, suggested a complex, hybrid structure of this lesion. Therefore the case could be classified as mixed malignant sweat gland tumor.
