Prompt treatment of impetigo reduces risk of spread

22 Jun 2020Paid-up subscribers

Impetigo is a common contagious bacterial infection of the skin. The causative organisms are either Staphylococcus aureus or, less commonly, Streptococcus pyogenes. The infection can occur at any age, but it is particularly common in children, especially the pre-school and early school age years, and tends to be more frequent during the summer months. It may arise on previously normal skin or complicate a pre-existing dermatosis. The diagnosis is essentially a clinical one, but if in doubt a swab should be taken for bacteriological culture.

Dermoscopy is a valuable diagnostic aid in primary care

24 Mar 2020

Dermoscopy as a clinical tool was developed primarily to evaluate pigmented lesions, particularly suspected melanoma. It is also useful in many other clinical situations, including the evaluation of a variety of benign and malignant skin tumours, inflammatory conditions, hair disorders, connective tissue diseases, and common infections and infestations. Images can be archived or exported for a second opinion and can also be shown to, and discussed with, the patient.
