Physiologic Skin Changes of Pregnancy PHYSIOLOGIC SKIN CHANGES OF PREGNANCY Barry Ladizinski Dartmouth Medical School Thursday, October 1, 2009 PHYSIOLOGIC SKIN CHANGES OF PREGNANCY The normal hormonal adjustments associated with the gravid state result in dermatologic changes that are known as physiologic skin changes or skin changes of endocrine origin. These common and benign manifestations include changes in connective tissue, hair, nails, glandular activity, pigmentation and vasculature. Typically, these cutaneous changes resolve postpartum, although some may persist in a less marked form.

  • Frequency of Different Types of Facial Melanoses Referring to the Department of Dermatology and Venereology, Nepal Medical Colle
    Amatya et al. BMC Dermatology (2020) 20:4 https://doi.org/10.1186/s12895-020-00100-3 RESEARCH ARTICLE Open Access Frequency of different types of facial melanoses referring to the Department of Dermatology and Venereology, Nepal Medical College and Teaching Hospital in 2019, and assessment of their effect on health-related quality of life Bibush Amatya* , Anil Kumar Jha and Shristi Shrestha Abstract Background: Abnormalities of facial pigmentation, or facial melanoses, are a common presenting complaint in Nepal and are the result of a diverse range of conditions. Objectives: The objective of this study was to determine the frequency, underlying cause and impact on quality of life of facial pigmentary disorders among patients visiting the Department of Dermatology and Venereology, Nepal Medical College and Teaching Hospital (NMCTH) over the course of one year. Methods: This was a cross-sectional study conducted at the Department of Dermatology and Venereology, NMCT H. We recruited patients with facial melanoses above 16 years of age who presented to the outpatient department. Clinical and demographic data were collected and all the enrolled participants completed the validated Nepali version of the Dermatology Life Quality Index (DLQI). Results: Between January 5, 2019 to January 4, 2020, a total of 485 patients were recruited in the study. The most common diagnoses were melasma (166 patients) and post acne hyperpigmentation (71 patients). Quality of life impairment was highest in patients having melasma with steroid induced rosacea-like dermatitis (DLQI = 13.54 ± 1.30), while it was lowest in participants with ephelides (2.45 ± 1.23). Conclusion: Facial melanoses are a common presenting complaint and lead to substantial impacts on quality of life.

  • Skin Care, Hair Care and Cosmetic Treatments in Pregnancy and Breastfeeding
    Skin Care, Hair Care and Cosmetic Treatments in Pregnancy and Breastfeeding Information in this leaflet is general in nature and should not take the place of advice from your health care provider. With every pregnancy there is a 3 to 5% risk of having a baby with a birth defect. Issues for pregnancy Many pregnant women have skin and hair concerns just as they did before pregnancy. Sometimes conditions such as acne actually worsen during pregnancy because of hormonal changes and often women notice darkening of their skin (melasma). However, due to concern about potentially hazardous exposures to their unborn babies, pregnant women are often uncertain about which products are safe for them to use. Generally cosmetic treatments are discretionary (not medically necessary) and if safety is uncertain, women should consider whether the product or treatment is really required. There are several considerations when evaluating whether a specific skin or hair product is unsafe in pregnancy. Firstly, the active ingredient in the product needs to be considered unsafe. Secondly, it also has to be able to reach the unborn baby in its mother’s womb by inhalation or absorption through the mother’s skin (topical application). Although there is often limited information about the actual safety of specific ingredients in skin products during pregnancy, if it is known that skin absorption is minimal then the exposure to the unborn baby is generally insignificant and the product or treatment is regarded as safe. Below is a summary of current advice. Cosmetics, Moisturisers and other Skin Care Products Cosmetics and over the counter skin products generally contain ingredients that are unlikely to be harmful in pregnancy as they are used by applying to the skin (rather than swallowing a tablet).

  • A New Insight on Atopic Skin Diathesis: Is It Correlated with the Severity of Melasma
    A New Insight on Atopic Skin Diathesis: Is It Correlated with the Severity of Melasma Danar Wicaksono1*, Rima Mustafa2, Sri Awalia Febriana1, Kristiana Etnawati1 1 Dermatovenereology Department, Faculty of Medicine Universitas Gadjah Mada – Dr. Sardjito General Hospital, Yogyakarta-Indonesia 2 Clinical Epidemiology and Biostatistics Unit, Faculty of Medicine Universitas Gadjah Mada –Dr. Sardjito General Hospital, Yogyakarta-Indonesia Keywords: Melasma, atopic skin diathesis (ASD), MASI score, atopic dermatitis (AD) Abstract: Melasma is a macular lesion of light brown to dark on the sun-exposed area, especially on the face. Atopic Skin Diathesis (ASD) is a clinical term to describe skin atopics with previous, present or future atopic dermatitis (AD). Dennie-Morgan infraorbital folds are secondary creases in the skin below the lower eyelids with a sensitivity of 78% and a specificity of 76% to diagnose AD. Melasma skin is characterized by impaired stratum corneum integrity and a delayed barrier recovery rate. Barrier dysfunction will stimulate keratinocyte to secrete keratinocyte-derived factor, which plays role in skin pigmentation process in melasma. To analyze correlation between ASD and Melasma Area Severity Index (MASI) score in melasma patient. This study is an observational analytic study with cross sectional design. Measurement of ASD and MASI score were done in 60 subjects with melasma who went to dermatology outpatient clinic Dr. Sardjito General Hospital from July 2017 to Januari 2018. The correlation between ASD and MASI score was analyzed using Pearson correlation. The result of this study showed no significant correlation between ASD and MASI scores (r: 0.02, p: 0,85). Crude Relative Risk (RR) for Dennie-Morgan infraorbital folds and MASI score was 4 (1.01-15.87).

Wallace, DNP, MSN, CRNA SAFETY OF Over-the-Counter MEDICATIONS IN PREGNANCY Abstract Approximately 90% of pregnant women use medications while they are pregnant including both over-the-counter (OTC) and prescription medications. Some medica- tions can pose a threat to the pregnant woman and fetus with 10% of all birth defects directly linked to medications taken during pregnancy. Many medications have docu- mented safety for use during pregnancy, but research is limited due to ethical concerns of exposing the fetus to potential risks. Much of the information gleaned about safety in pregnancy is collected from registries, case studies and reports, animal studies, and outcomes management of pregnant women. Common OTC categories of readily accessible medications include antipyretics, analgesics, nonsteroidal anti- infl ammatory drugs, nasal topicals, antihistamines, decongestants, expectorants, antacids, antidiar- rheal, and topical dermatological medications. We review the safety categories for medications related to pregnancy and provide an overview of OTC medications a pregnant woman may consider for management of common conditions.

  • Lupus Mimickers
    Lupus Mimickers Arup Kumar Kundu, Somak Kumar Das INTRODUCTION Systemic lupus erythematosus is considered as “the great mimic of other conditions”. Conversely there are many diseases which can mimic SLE as a systemic disease or as dermatological, rheumatological, vasculitic, or immunological mimickers. This monograph is restricted to the lupus mimickers only, not the discussion on SLE. DERMATOLOGICAL MIMICKERS OF S.L.E. 1,2 I. Dermatological conditions mimicking acute cutaneous lupus erythematosus (LE) Rosacea: Rosacea is characterized by erythema of the central face that has persisted for months or more. The convex areas of the nose, cheeks, chin, and forehead are the characteristic distribution [Fig. 1]. Triggers of rosacea may include hot or cold temperature, sunlight (hence, photosensitive), wind, hot drinks, spicy foods, exercise, emotions, alcohol, cosmetics, topical irritants, menopausal flushing, medications etc. Erythematotelangiectatic subtype and papulopustular subtype may mimic acute cutaneous LE. The malar erythema of lupus erythematosus [Fig. 2] can be difficult to differentiate from rosacea3. The presence of pustules and papules or blepharitis favors a diagnosis Fig.1: Acne Rosacea of rosacea, while fine scaling, pigment change, follicular plugging and scarring favor a diagnosis of lupus.

  • Medical Advances for Uneven Skin Tone the Most Effective Approach
    Skin Health FROM THE MOUNT SINAI DEPARTMENT OF DERMATOLOGY WINTER 2013 MOHS SURGERY The Most Effective Approach to Skin Cancer By David A. Kriegel, MD ore than two million Americans are diagnosed with skin M cancer every year. Of the many different types of cancer that affect the skin, two account for the vast majority of cases: basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). For the most part, these can be prevented by limiting sun exposure, always using sunscreens for outdoor activities, and avoiding indoor tanning. Yearly skin cancer screening and follow-up treatment by a dermatologist help to detect dangerous skin lesions and keep them from spreading. Between yearly screenings, I advise patients to examine their skin every three or four months, using mirrors to look at their backs and scalps. Most cases of BCC and SCC can be cured if caught early enough. A tissue map enables Mohs surgeons like Dr. Kriegel to remove cancerous continued on page 3 cells while preserving the surrounding normal skin.
