Altered Skin and Gut Microbiome in Hidradenitis Suppurativa.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by the formation of nodules, abscesses, and fistulae at intertriginous sites. The skin-gut axis is an area of emerging research in inflammatory skin disease and is a potential contributory factor to the pathogenesis of HS. A total of 59 patients with HS provided fecal samples and nasal and skin swabs of affected sites for analysis.

An Update on Health-Related Quality of Life and Patient-Reported Outcomes in Hidradenitis Suppurativa.

Hidradenitis suppurativa is a common inflammatory skin condition which causes recurrent abscesses, sinuses and scarring in the axillae, groin and inframammary areas. As well as causing significant physical distress due to pain and discharge, the condition impacts psychological well-being with markedly impaired quality of life. Patients suffer pain, embarrassment and psychological distress with impairment of their work and intimate relationships marking it as one of the most distressing dermatological conditions.

Could isotretinoin flare hidradenitis suppurativa? A case series.

We report eight cases of patients with severe acne who were treated with isotretinoin and developed painful nodules in the axillae and groin, consistent with hidradenitis suppurativa (HS). The pathogenesis of HS is still not completely understood; recent research from a study in 2011 of biopsies from HS lesions showed a reduction or absence of sebaceous glands compared with normal skin in patients with HS, with the report suggesting that this contributes to the pathogenesis of the disease. Interestingly, the main effect of isotretinoin is to decrease the size and action of sebaceous glands, so hypothetically, as isotretinoin acts by reducing the sebaceous glands further it could potentially aggravate HS.

Hidradenitis Suppurativa and Crohn's Disease: A Case Series.

Hidradenitis Suppurativa (HS) is characterized by chronic recurrent abscesses, nodules and draining sinus tracts with scar formation. Cutaneous Crohn's Disease (CD) may also present similarly. We wished to identify and describe an Irish cohort with combined HS and CD, with a view to a better recognition of clinical manifestations and understanding of the pathophysiology underlying these two overlapping conditions.

A cross-sectional epidemiological study of hidradenitis suppurativa in an Irish population (SHIP).

Background: Hidradenitis suppurativa (HS), a chronic inflammatory disease that affects apocrine gland-bearing skin, has a significant impact on patients' quality of life. Estimates of the epidemiologic prevalence of HS are highly variable, and clinical data on disease characteristics and patient burden of disease remain limited.

Objective: The primary objective of this study was to determine the number of patients with HS attending dermatology clinics in a hospital setting in Ireland (within a 6-month time period).

Hidradenitis Suppurativa Is Characterized by Dysregulation of the Th17:Treg Cell Axis, Which Is Corrected by Anti-TNF Therapy.

Hidradenitis suppurativa (HS) is a chronic, inflammatory, and debilitating disease of hair follicles with 1-4% prevalence and high morbidity. There is a dearth of information on the pathogenesis and immune dysregulation underlying HS; therefore, we carried out a detailed analysis of skin-infiltrating T cells. Cells isolated from skin biopsy samples and blood from HS patients and healthy control subjects were analyzed by 16-parameter flow cytometry to provide detailed profiles of CD4 T-cell subsets.

Heart rate variability changes in business process outsourcing employees working in shifts.

Background And Objectives: Irregular and poor quality sleep is common in business process outsourcing (BPO) employees due to continuous shift working. The influence of this on the cardiac autonomic activity was investigated by the spectral analysis of heart rate variability (HRV).

Methods: 36 night shift BPO employees (working from 22:00 to 06:00h) and 36 age and sex matched day shift BPO employees (working from 08:00 to 16:00h) were recruited for the study.
