Background:Allergic contact dermatitis (ACD) is a delayed type of hypersensitivity from contact with a specific allergen to which the patients has developed a specific sensitivity. The aim of the study was to evaluate the results of epicutaneous patch testing with standard series of contact allergen in patients suspected to have ACD.Methods:355 cases of ACD were included in the study. Test substances were applied on the upper part of the patient’s back, on clinically uninvolved and untreated skin. All patients were free from therapy with oral antihistamines, steroids and immunosuppressants. The patch test was removed and reaction were evaluated after 48 h and 72 h. Grading of negative (-) to positive (+ to ++++) patch test was done according to the International Contact Dermatitis Research Group. Statistical data analysis was performed by using χ2–test.Results:Of the 355 cases, 146 patients were male (41.1%) and 209 were female (58.9%). The youngest patients in the study was 16 years of age and the oldest was 67 years of age. The commonest age group affected was 41-50 years. Hands were the most common site of involvement. The occupational character of skin lesions was find in 75 (21.1%). The most common positive reactions were recorded to nickel sulphate 99 (27.8%), cobalt chloride 46 (12.9%), thimerosal 31 (8.7%), colophony 23 (6.5%), carba mix 21 (5.9%), potassium dichromate 20 (5.6%), acid chromici 19 (5.3%), fragrance mix 18 (5%), balsam of Peru 13 (3.7%), formaldehyde 9 (2.5%), and other allergens 26 (7.3%). Females were significantly more likely to show a positive response to two or more allergens (p<0.05). There was no statistically significant impact of age, occupation and duration of disease on results of patch testing (p>0.05).Conclusions:Our results indicate that nickel sulphate, cobalt chloride and thimerosal are the most common allergens responsible for induction of ACD. These findings are crucial in the treatment, long term management, an education of patients with ACD.

Annotation. Despite the prevalence of seborrheic dermatitis (SD), especially among young people, little is known about its clinical and anamnestic features in the population of Ukraine. To fill this gap, it is necessary to conduct a study of reliable data obtained from the domestic sample of working age. The aim of the study is to find the clinical and anamnestic features of men and women with generalized fatty form of seborrheic dermatitis of varying severity. A survey of 40 men and 40 young women (25-44 years according to the age periodization of the WHO, 2015) in patients with generalized fatty seborrheic dermatitis was conducted on the basis of the Department of Skin and Venereal Diseases with a postgraduate course in National Pirogov Memorial Medical University, Vinnytsya and the Military Medical Clinical Center of the Central Region. Retrospective analysis included assessment of passport, anamnestic, clinical data. Diagnosis of SD was established on the basis of complaints of the subject, life history and illness, examination of the face, scalp, torso and extremities with the assessment of subjective and objective signs of the disease. Statistical analysis was performed using the license package “Statistica 6.0”. It was found that the severity of SD increased with increasing length of service and depended on the type of professional activity. Stress, temperature, humidity, smoking, heredity caused the manifestation or exacerbation of dermatosis. Acne and rosacea often accompanied severe SD. Itching and oiliness of the skin, rash on the head and face, erythematous spots and plaques, the predominance of red dermographism were observed in both types of flow, and the feeling of dirt, localization of pathological elements on the body, sebaceous scales – only in severe. Thus, the data obtained in our study can form the basis for the development of an algorithm for monitoring patients with generalized seborrheic dermatitis of varying severity.

Background Scalp psoriasis is often undiagnosed or inadequately treated. The patient himself underestimates the seriousness of this hair disease and consults too late to a dermatologist. Objectives The aim of our study was to create a correlation between the clinical patterns and trichoscopy of scalp psoriasis such in a way to help the clinician to make the diagnosis and select the appropriate therapy. Material and methods We gathered all patients affected of scalp psoriasis afferent to Outpatient's hair consultation of the Department of Experimental, Diagnostic and Specialty Medicine, University of Bologna, from January 2012 to December 2018. All patients were evaluated through clinical, trichoscopic examination and a skin biopsy only in doubtful cases. We quantified the severity of the disease with several objective and subjective parameters every 4 months, up to 1 year. We recorded therapies, outcome data and quality of life. Results We collected 156 patients affected by scalp psoriasis, identifying seven clinical patterns with specific trichoscopical correlation. In the order of frequency, the clinical patterns were as follows: plaque psoriasis (with a prevalence of erythema, silver‐white scales and twisted red loops vessels and red dots); thin scales (with silvery‐white scales, simple red lines and signet red ring vessels); sebopsoriasis (with greasy scales, erythema with red dots, globules and twisted and bushy red loops at high magnification); psoriatic cap (with silver‐white scales, erythema and polymorphic vascular pattern); pityriasis amiantacea (with yellowish adherent scales, erythema and simple red loops capillaries); cicatricial psoriatic alopecia (with erythema associated with yellowish, silver‐white scales with twisted and bushy red loops capillaries) and pustular psoriasis (with ‘flower shape’ pustular lesions, erythema simple red loops capillaries). Conclusions The description of different clinical patterns of scalp psoriasis and its trichoscopical correlations may help the clinician to make the diagnosis also in atypical presentations and to prescribe an adequate therapeutic regimen.
