Maintaining skin integrity
The prevalence of dry skin complaints from both healthy individuals and patients with certain skin diseases is increasing. Dry skin is thought to be associated with ageing, environmental factors and genetic disorders and is usually due to impaired skin barrier function.
Beyond the atopic march
Atopic dermatitis (AD), also known as eczema, is a chronic, inflammatory skin disease of unknown origin that often starts during early infancy. In recent years, research has indicated that it might be a precursor condition to more severe conditions, including CVD.
Update, equip, improve dermatology practice in South Africa
This article is based on presentations given by leading dermatology and allergology practitioners at a recent symposium hosted by Mylan Derma.
Histological clearance of basal cell carcinoma
Basal cell carcinoma (BCC) is the most frequent occurring malignant tumour among human populations worldwide, with an increasing incidence rate over the last decade. It alone accounts for 90% of all skin cancers.
What to do about hyperpigmentation?
Facial melanoses have always been cosmetically and psychologically disturbing to the patients. Despite great recent advancement in dermatology, treating facial melanoses remains a challenge to doctors and is equally frustrating for patients.
Topical treatment for onychomycosis
Nail fungal infections are the most common diseases of the nails, making up almost half of all nail abnormalities. Both fingernails and toenails are susceptible to infection, which usually appears as discolouration and thickening of the nail.
Link found between atopic dermatitis and salt
A team from the Technical University of Munich has demonstrated that salt leads to the formation of Th2 cells, immune cells active in allergic conditions such as atopic dermatitis.
Delving deeper into basal cell carcinoma
Basal cell carcinoma (BCC) is the most common skin cancer, with a rapidly growing prevalence in countries with majority white populations. Even though a number of treatment strategies exist, only surgery and topical treatments provide an optimal outcome.
Xerosis: a focus on black skin
Doctors should provide evidence-based information about emollients for patients of African origin, since both hyperpigmentation and lichenification are different for black skin types than white or Asian skin types.
Identification and care of external genital warts
Genital warts are a symptom of certain types of human papillomavirus (HPV) infection and result in significantly reduced quality of life. A number of treatment options are available, but efficacy rates vary dramatically between treatments.
Banish fungal nail infections for good
Fungal nail infections, also referred to as onychomycosis, may affect one or more nails of the fingers or toes but most often involve the great toenail.
Treating acne
While acne should be treated actively to avoid unnecessary scarring and psychological distress, the choice of treatment is dependent on the severity of the presenting acne.
Alopecia during cancer treatment
Alopecia or baldness is a distressing problem to both males and females. Although hair loss is a given with certain forms of cancer treatment, there are treatments that can mitigate these effects.
How to identify an STI
It is not always easy for a medical practitioner to identify an STI on examination only and it is useful to understand the various dermatological presentations of STIs.
Solar keratoses
Actinic or solar keratoses are keratotic lesions occurring on chronically light-exposed adult skin. They represent focal areas of abnormal keratinocyte proliferation and differentiation that carry a low risk of progression to invasive squamous cell carcinoma (SCC).
Pigmentation and the sun
Excessive, unprotected exposure to solar radiation can lead to accelerated photo-ageing, carcinomas and disorders of skin pigmentation. Hyperpigmented lesions may be of aesthetic concern alone, or represent premalignant and malignant lesions.
Psoriasis can cause psychological stress
Psoriasis is a common, chronic inflammatory skin condition. It is thought to be immune-mediated; however, genetic and environmental factors are aetiological contributors.
Breaking the barrier
A skin infection occurs when there is a breach in the skin barrier due to various causes, like injury, diseases, inoculation, warmth, humidity and poor hygiene.
Cosmetic utility of imiquimod in actinic keratosis
Actinic keratosis is one of the most common dermatological conditions, but current treatments are often not cosmetically optimal, with scarring and permanent hypo- or hyperpigmentation often a result.
