Hidradenitis Suppurative-Acne Inversa is one of the most debilitating chronic skin diseases. It seriously affects the emotional and relational life of the patient, it has a significant psychiatric comorbidity and it impairs the quality of life. We present the report of a clinical situation with onset of the illness in a young woman during pregnancy, a case characterized by particular evolution, severe systemic involvement, strong psycho-emotional impact on the patient and impairment of subjective well-being of the caregiver...

Hidradenitis suppurativa / acne inversa (HS) is a chronic inflammatory, debilitating skin disorder with a largely unknown etiology. However, many observations such as the typical onset of the disease after puberty, the female predominance, the pre-menstrual flare ups and the improvement during pregnancy suggest a contribution of endocrinological factors to the emergence of the disease. In addition, the reported efficacy of anti-androgen treatment on HS indicates a possible involvement of androgens in the pathogenesis...

Hidradenitis suppurativa/acne inversa (HS) has a multifactorial pathogenesis, with many patients reporting positive family history. Nine β-defensin genes (among them DEFB4 and DEFB103, encoding for proinflammatory mediators human β-defensin-2 and human β-defensin-3, respectively) exist as a cluster (DEFB) affected by copy number (CN). We hypothesized that CNs are greater in patients with HS and that they are linked to genetic susceptibility. CNs of DEFB were studied in two independent patient cohorts: 163 patients from Greece and 98 from Germany...

Hidradenitis suppurativa/acne inversa (HS) is a chronic inflammatory skin disease characterized by painful, recurrent nodules and abscesses that rupture and lead to sinus tracts and scarring. To date, an evidence-based therapeutic approach has not been the standard of care and this is likely due to the lack of evidence based treatment guidelines. The purpose of this study was to promote a holistic evidence-based approach which implemented Level of Evidence and Strength of Recommendation for the treatment of HS...

PURPOSE: Free flap transplantation to vascular reconstructions as arteriovenous (AV) loops has been established in centers as a feasible therapeutic option for defect reconstruction in the absence of proper recipient vessels, caused by oncologic resections, radiation, or trauma. We report our 10-year experience in free flap transplantation after vascular reconstruction with special emphasis on complication rate and postoperative mobility. PATIENTS AND METHODS: Forty-seven patients (mean age: 60 years, range: 19-86) were included...

Hidradenitis suppurativa (HS), also known as acne inversa, is a chronic, recurrent inflammatory disease affecting skin that bears apocrine glands. It is characterised by the presence of tender subcutaneous nodules that may rupture, resulting in deep dermal abscesses, fibrosis with dermal contractures and induration of the skin. The management of HS is a challenge for physicians as the pathogenesis is not clearly defined and prevents the use and development of directed therapies. Treatment options are oral agents (antibiotics, immunomodulators) and surgical excision...

Hidradenitis suppurativa is a chronic inflammatory disease of apocrine gland-bearing skin. Although immunologic derangements, genetic predisposition, obesity, and smoking are likely important factors, the pathogenesis of the disease and the effect of available treatments on disease course have not been fully elucidated. In the absence of proper treatment, chronic inflammation results in diffuse scarring and a wide array of complications, including the development of cutaneous squamous cell carcinoma. This severe and chronic disease can have detrimental effects on self-esteem and quality of life...

INTRODUCTION: Hidradenitis suppurativa (HS) is a chronic, disabling, skin disorder. Because of renewed scientific interest in HS, different aspects of the condition, such as disease severity assessment, are being investigated and better defined. The aim of this study is to provide a novel tool for the assessment of disease severity. METHODS AND MATERIALS: An HS-tailored, composite, dynamic score, named the Acne Inversa Severity Index (AISI) was designed to include a physician-rated assessment that considers the type of lesions occurring and the affected body sites...

BACKGROUND: Acne inversa (AI) is a chronic inflammatory skin disease with an autosomal dominant inheritance pattern. Mutations of the gene encoding nicastrin (NCSTN), a cofactor subunit of γ-secretase, are responsible for familial AI. However, whether deficiency of nicastrin is functionally implicated in the biological behaviours of human keratinocytes and related molecular mechanisms remains unknown. OBJECTIVES: To study alterations of biological traits and related signalling pathways modulated by nicastrin knockdown in keratinocytes...

The pathogenesis of hidradenitis suppurativa (HS) or acne inversa is not completely understood. Recent research has led to greater insight into the mechanisms involved in the disease. The primary defect in HS pathophysiology rests with the hair follicle. Follicular occlusion, followed by follicular rupture, and a foreign body-type immune response are necessary conditions for the development of clinical HS. A specific genetic signature and environmental factors, such as cigarette smoking, microbial colonization, and adiposity, all contribute to the HS phenotype...

When the prevention of new lesions fails and when medical therapy of established and growing lesions is ineffective, surgery is the accepted method of dealing with hidradenitis suppurativa/acne inversa. The rationale and preferred techniques of mini-unroofing using a biopsy punch, deroofing using scissors, electrosurgery or laser, and classical wide excision and closure are discussed. The situation in which incision and drainage is considered for temporary pain relief would be best considered an opportunity for deroofing, as illustrated in the accompanying online videos...

Full control of hidradenitis suppurativa requires the prevention of new lesions. These appear to be induced by a complex series of hormonally driven molecular activities that lead to obstruction of the follicular duct, rupture and destruction of the sebaceous glands, the development of deep dermal sinuses that subsequently rupture to the surface, and production of an invasive subcutaneous mass that is resistant to medical therapy. Preliminary observations suggest that the use of a healthy and fully natural zero dairy and low glycemic-load diet may provide relief from progression of the lesions and possibly prevention of new lesions, even when medications fail...

Given that follicular papules and pustules, as well as nodules and abscesses, are the clinical hallmarks of hidradenitis suppurativa (HS), an infectious, bacterial pathway has been suspected in the pathogenesis of this chronic, inflammatory condition. Elucidating the behavior and role of bacterial species in HS and their interaction with cutaneous innate immunity will provide more insight into the pathophysiology of this condition. This review of prospective investigations suggests a synergistic relationship between impaired innate immunity and microbial factors in the etiology of HS...

BACKGROUND: The pathogenesis of the chronic inflammatory skin disease hidradenitis suppurativa (HS, also known as acne inversa) involves epidermal alterations such as psoriasiform epidermal hyperplasia and keratin plugging. Keratinocytes are an important source of proinflammatory molecules in inflammatory skin diseases and can be stimulated by interleukin (IL)-17(+) cells. OBJECTIVES: To explore the possible role of the epithelium in the pathogenesis of HS. METHODS: We performed immunohistochemical stainings and Western blot experiments to investigate the localization and expression of inflammation-associated molecules, including the cytokine IL-17, components of the inflammasome including caspase-1, and the endogenous danger-associated molecular pattern molecules S100A8 and S100A9 (calprotectin)...

Acne inversa (hidradenitis suppurativa) is a potentially severe and chronic inflammatory disease with a significant negative influence on the quality of life. Usually, lesions are located in the areas of skin folds and it is characterized by the presence of painful nodules and fistulas with a tendency to tissue fibrosis. Currently, it is suggested that follicular occlusion by infundibular hyperkeratosis plays a crucial role in pathogenesis and an occupation of apocrine sweat glands is a secondary phenomenon...
