Scabies –still current medical and social problem. A retrospective analysis of 193 cases

Scabies is a parasitic skin disease caused by Sarcoptes scabiei. About 200 million casesworldwide each year in people of all ages are reported.

Retrospective analysis of records of patients hospitalized at the Department with scabies.

Six-year retrospective analysis of medical records of patients hospitalized with scabies at the Department of Dermatology. Gender, age of patients, comorbidities, clinical course of the disease and treatment were considered.

In this period 193 patients were hospitalized with scabies, 96 females (49.7%) and 97 males (50.3%), including 33 children (17%). Mean age of patients was 52.9. Skin lesions persisted 142 days in average; reoccurrence was noted in 14% of cases. Lesions were observed most often in winter (31%). The most common manifestations were erosions (80.8%), excoriations (73.6%), papules (72.6%) and crusts (24.3%), localized mainly on trunk (92%), lower (91%) and upper (86%) limbs. 181 patients (93.8%) reported pruritus which intensified at night in 35.8%. Previous contact with people with scabies reported 41 patients (21%). The most common comorbidity was hypertension, diabetes mellitus and coronary heart disease. Accompanying dermatoses were eczema, secondary superinfection and psoriasis. 85 patients (44%) were overweight or obese. Patients received mostly topical permethrin (57%), crotamiton (29%), glicocorticosteroids (73%) and antibiotics (11%), also oral antihistamines (91%).

Analysis revealed more frequent occurrence in adults with no evident sex prevalence. Greater incidence in winter may be caused by people’s tendency to spend more time indoors closer to each other at this time of year. Pruritus, the most common subjective symptom, typically worsens at night.
