Dermatologic diseases and problems of women throughout the life cycle

Xerosis cutis and associated co-factors in women with prurigo nodularis

BACKGROUND

Current data regarding the associated factors of prurigo nodularis are still uncertain, except for atopic predisposition.

OBJECTIVES

The purposes of this study were to (1) determine the frequencies of xerosis and other accompanying diseases of female patients with prurigo nodularis; (2) compare the demographic, clinical and accompanying disease characteristics by grouping these patients according to whether they have associated xerosis (who were subsequently subgrouped as atopic or non-atopic) or not.

METHODS

In this retrospective descriptive study, 80 females with PN were categorized according to the accompanying diseases (dermatological, systemic, neurological, psychogenic, mixed, or undetermined origin).

RESULTS

A total of 45 associated co-factors including dermatological in 63 (78.8%), systemic in 57 (71.3%), psychological in 33 (41.3%) and neurological co-factors in 14 (17.5%) of all patients with prurigo nodularis were detected. Xerosis was observed in 48 (60%) patients (non-atopic co-factors in 66.7% of them). The ratio of patients with mixed co-factors, dermatological+systemic co-factors and dermatological+systemic+psychological co-factors were found to be significantly higher in patients with xerosis compared to those without xerosis.

STUDY LIMITATIONS

Our study has certain limitations such as the absence of an age-matched control group, absence of follow-up data and the fact that the diagnosis of xerosis has not been based on objective methods.

CONCLUSIONS

Xerosis has been identified in more than half of the patients with PN and it has been determined that in most patients xerosis is associated especially with diabetes mellitus and other conditions related to prurigo nodularis.

A retrospective analysis of dermatoses in the perimenopausal population attending a tertiary care centre in South India

Introduction:

Menopausal is a normal physiologic aging process in women characterized by decreasing estrogen levels. The skin is an organ dependant on hormones, estrogen being the most important in case of females, thereby influencing both the biology of skin and composition. Studies show that the systemic effects of estrogen deprivation occur years after attaining menopausal, however cutaneous features have been noticed earlier. The purpose of this study is to evaluate the common disorders occurring in perimenopausal women of Indian ethnicity.

Materials and Methods:

A retrospective observational study of outpatient records from Dermatology clinic between 2005 and 2012. All female patients between 45-55 years of age from an outpatient register that outlines the final diagnosis made by a qualified dermatologist after investigations. The data was entered according to the pattern of dermatoses and their seasonal variation and analyzed were included.

Results:

A total of 8,156 cases were found. After analysis of the many variables, the most common dermatoses in the perimenopausal population were eczematous disorders (23.6%), followed by urticaria (12.4%) and papulosquamous disorders (10.7%). Of the eczematous disorders, allergic and photosensitive disorders were found to be more frequent.

Conclusion:

The leading dermatoses being eczema and urticaria in the perimenopausal population probably accounts for a tendency of exaggerated response to external factors. The population studied in the current study might be of significance due to complete lack of treatment in the form of hormone replacement therapy (HRT), while routine sun exposure and cultural practices predominate. However, evaluation with respect to individual factors is beyond the scope of the current study and may be necessary to define a causal relationship.

Menopause and the skin

Women live one-third of their lives in the post-menopausal state. Significant hormonal alterations occur at the time of menopause, leading to a range of physiological disorders affecting multiple organ systems in the body. The effects of menopause on the skin have been underresearched. Many skin changes occur at the time of menopause and the cutaneous effects of hormone replacement therapy are significant. Menopausal changes in hormones may alter the biomechanical properties of the skin and certain disorders are more common in menopausal women, such as lichen sclerosus, atrophic vulvovaginitis, flushing and dysaesthetic vulvodynia. Hair and oral changes may also be associated. As the average life expectancy increases, dermatologists need to be familiar with skin diseases affecting women in this age group.

Common dermatoses of pregnancy

Awareness of pregnancy-related skin changes can facilitate improved care of women during pregnancy by identifying those skin changes that require further evaluation. Women experience significant endocrine and metabolic changes during pregnancy that can cause both physiologic and pathologic alterations in the skin, nails, and hair. This review discusses the physiologic changes and pruritic dermatoses that are specifically associated with pregnancy. The effect of pregnancy on preexisting skin diseases and safe treatment options for usage during pregnancy will be provided.
