Abstract
Hidradenitis suppurativa (HS) is an inflammatory follicular dermatological condition that typically affects the intertriginous and anogenital regions of the apocrine gland-bearing skin. The management of this chronic and recurring disease necessitates a combination of lifestyle changes, medication, and surgical approaches to achieve the best possible outcomes. While medical treatments are recommended for this multimodal disease, surgical therapy, which is the gold standard of treatment for HS, has proven to be the most effective treatment because it provides long-lasting local disease control, reduces the recurrence of lesions, and ensures complete healing of lesions. In the last decade, there has been exponential growth in research into various surgical techniques and reconstructive care, enabling patients to have more surgical options. There is a wide range of surgical management procedures available, such as incision and drainage, deroofing, excisional surgery, carbon dioxide laser therapy, and skin tissue-sparing excision with electrosurgical peeling. Among these surgical procedures, wide surgical excision is the best option since it can eradicate all the affected lesions. Meanwhile, the preferred approach to reconstruction at various anatomical locations remains debatable. Here, we review a variety of surgical treatments and reconstructive techniques for HS, particularly various flap techniques for the axillary, gluteal, and inframammary regions.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a debilitating chronic skin disease; its therapeutic approach often requires combined medical and surgical treatment. METHODS The aim of this study was to assess the efficacy and safety of the surgical approach combined with different pharmacological treatments, evaluating the proportion of patients achieving the hidradenitis suppurativa clinical response (HiSCR), along with the incidence of postoperative complications, and local recurrence. A retrospective study of HS patients (Hurley I-III) presenting at least one skin lesion requiring surgery was performed. Demographic and clinical data were collected (kind and anatomical location of lesion excised, type of surgical procedure). Further data included: Hurley stage and IHS4 at baseline and week 16, HiSCR at week 16 after surgery, ongoing therapy at the time of surgery (topical, systemic antibiotic, biologics), postoperative complications and local recurrence at week 16. RESULTS Forty-two patients with female predominance (66.7%, 28/42), with a mean age of 30.3 (SD±10.5) years, were enrolled. At week 16, 53% of patients achieved HiSCR, with baseline Hurley III inversely related to HiSCR achievement (P<0.05). No increased incidence of postoperative complications was detected. Three cases of local recurrence were reported at week 16. CONCLUSIONS The results support the efficacy and safety of the combined therapy in the management of HS; no increased risk of complications emerged among patients concomitantly treated with biologics, compared to those on conventional systemic therapy or exclusively treated with surgery.

Abstract
Hidradenitis suppurativa (HS) is an inflammatory disease causing nodules, abscesses, sinus tracts, and scars in fold areas. It significantly impacts patients' quality of life. Surgical treatments are becoming popular in dermatology, with deroofing being a common procedure. However, recurrence rates can be high due to not removing fibrotic areas and scar tissue entirely. Recent efforts have focused on removing these tissues to achieve lower recurrence rates. This case report describes a male patient with HS who underwent a newly defined ultrasonography-guided modified deroofing surgery for HS. The wound-healing process was then accelerated with the application of topical insulin. In this case, we would like to highlight the significance of using ultrasonography before HS surgery, confirm the importance of modified deroofing surgery, and emphasize that insulin can be used as an effective supplementary treatment for ulcer management.

Abstract
Hidradenitis suppurativa (HS) is a disease with a poor prognosis, often misinterpreted as an infection, with the highest impact on the patient's quality of life among all the assessed dermatological diseases. The main aim of this study was to compare various therapeutic interventions that are currently available for the treatment of HS. The pathogenesis of HS is not well understood, but it is mostly multifactorial involving a number of factors like genetic factors, androgens, local immunity, microflora, smoking, and obesity. Despite limited evidence on their effectiveness, topical antibiotics and antiseptics are commonly employed. Due to the colonization of bacteria and the presence of biofilms in the sinus tracts formed by HS lesions, systemic antibiotics are commonly employed as the primary form of therapy. In females with HS who experience menstrual flares or display symptoms of polycystic ovary syndrome, hormonal agents are often considered to be a viable and effective therapeutic option. At present, the sole treatment approved by both the Food and Drug Administration and the European Medicines Agency for addressing moderate to severe HS is adalimumab, an antibody that targets tumor necrosis factor alpha. Many surgical procedures in the management of HS aim to address inflammation by eliminating the affected folliculo-pilosebaceous unit, sinus tracts, and associated debris to impede further progression and scarring. HS continues to pose a considerable treatment challenge, necessitating a comprehensive approach for patients. However, the available evidence for most of these treatments is limited, indicating the need for more extensive research to identify the most effective interventions for managing HS.

Abstract
Hidradenitis suppurativa (HS), a chronic disease of the apocrine bearing skin causing induration, pain, draining sinuses, and subcutaneous abscesses, significantly impairs patients' quality of life (QOL). Full-thickness excision followed by skin grafting of the involved area can be curative. Herein, we evaluated the impact of this surgical treatment on QOL and depression symptomatology. Adult patients (≥18 years) who consented to participate filled out the dermatology quality of life (DLQI) and the Patient History Questionnaire (PHQ-9) at consent and at 1, 6, and 12 months post-initial evaluation and surgery. Demographics, HS, admission, and operative information were collected. Sixteen patients were included. Subjects were mainly white (81.3 %) and female (56.3%) with a median age of 38.2 (Interquartile range: 34.2-54.5); 62.5% were obese (BMI= 39.7 [28.4-50.6]). Half of the subjects presented with HS in 2 or more areas. Six patients were still undergoing surgeries at 6 months. One-, six-, and 12-month follow-up surveys were obtained from 14, 11, and 8 subjects for DQLI and from 14, 9, and 5 subjects for PHQ9. DLQI scores significantly decreased at 6 months compared to baseline, which indicates QOL improvement (10 [4-20] vs 15.5 [12-21.8], P = .036). Although not significant, PHQ9 scores tended to decrease. For those with the worst disease, DLQI significantly decreased at both 6 (P = .049) and 12 months (P = .047) compared to baseline. Despite a small sample size, our data suggest that aggressive surgical treatment improves the QOL of HS patients. Further studies are warranted to confirm our findings.

Abstract
Objective: Hidradenitis suppurativa (HS) is a painful inflammatory skin disease. Management is largely medical, with surgery reserved for severe refractory cases. In this study, we sought to conduct a retrospective analysis of a multi-institutional surgical database to investigate the surgical management of patients with HS and identify trends in the postoperative outcomes. Approach: The 2011-2019 American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was reviewed to identify patients who underwent surgery for management of HS. Postoperative outcomes were assessed, including surgical and medical complications, length of hospital stay, reoperation, readmission, and nonhome discharge. This article was reported according to the STROBE criteria. Results: We identified 1,030 patients, of which 62% were female and 50% were black. The most common comorbidity was obesity (61%). Surgery was mainly performed by general surgeons (62%) and plastic surgeons (31%). Complications were overall low, with readmission being the most common (7.1%, unplanned 6.0%), followed by reoperation (5.8%). The most common surgical complication was superficial incisional infection (5.1%) and most common medical complication was sepsis (3.8%). Obesity is seen to affect surgical complication rates, with patients with obesity having higher rates of dehiscence (obese: 3.1% and nonobese: 1.0%; p = 0.03) but lower rates of organ space infection (obese: 0.5% and nonobese: 2.0%; p = 0.03) and transfusion (obese: 2.5% and nonobese: 5.2%; p = 0.04). A focus on complications in patients undergoing flap reconstruction (n = 293; 23%), identified higher rates of surgical complications, with superficial incisional infection being the most common (flap reconstruction: 7.5% and incision and drainage, debridement, skin graft: 4.1%; p = 0.04). Innovation: The surgical management of HS is analyzed at the national level, with postoperative complications seen to depend on race and obesity-status. Conclusions: Surgical management for HS is associated with low postoperative complications, making surgery a viable treatment option for this debilitating disease.

Abstract
Introduction Hidradenitis suppurativa (HS) is a chronic, debilitating, recurrent, auto-inflammatory disease of the pilosebaceous units of the skin. The axillary region is the most affected anatomical site and its reconstructive options include skin grafts, local random plasties, regional axial flaps, and regional perforator flaps. The main aim of this systematic review is to identify the best surgical technique for axillary reconstruction in the context of HS, in terms of efficacy and safety. Methods We adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) throughout the whole review protocol build-up. The literature search was performed using MEDLINE, Embase, and Cochrane library databases, updated to March 2021. Quality was assessed for each study, through the National Institutes of Health Quality Assessment Tool. Results A total of 23 studies were included in the final analysis. We reviewed a total of 394 axillary reconstructions in 313 patients affected by HS Hurley Stage II or III. Skin grafts were associated with the highest overall complication rate (37%), and highest rate of reconstruction failure (22%). Between thoraco-dorsal artery perforator flap, posterior arm flap, and parascapular flap, the latter showed fewer total complications, recurrences, and failures. Conclusion Regional axial flaps should be considered as the best surgical approach in the management of advanced HS. The parascapular flap emerges as the most effective and safest option for axillary reconstruction. Local random flaps might be considered only for selected minor excisions, due to the higher risk of recurrence. The use of skin grafts for axillary reconstruction is discouraged.

Abstract
UNLABELLED Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder. Treatment of HS remains challenging, and surgical procedures commonly follow attempts of conservative therapy. To date, a consensus regarding the optimal surgical technique has not been reached, and the implications of conservative therapy on future surgical outcomes have yet to be studied. METHODS A retrospective cohort study of 65 patients surgically treated for HS at a tertiary care center was conducted. Patients' medical records were screened for demographical, clinical, and surgical characteristics. Statistical analysis was conducted to determine associations with postoperative complications and disease recurrence. RESULTS Fifty patients (75.8%) were treated with systemic antibiotics before opting for surgical resection. Previous treatment with systemic rifampicin was associated with higher rates of postoperative complications (P = 0.029); however, systemic cephalexin and topical clindamycin were associated with a lower rate of complications (P = 0.007 and 0.040, accordingly). Medical history of smoking and surgical management with split-thickness skin grafts were associated with higher rates of postoperative complications (P = 0.012 and 0.014, accordingly). Patients with a greater number of lesions, and those treated with split-thickness skin graft, had higher rates of disease recurrence (P = 0.0018 and 0.003, accordingly).In a multivariate analysis a greater number of lesions (P = 0.0498) and the use of autologous split-thickness skin graft (P = 0.022) were independently associated with higher rates of disease recurrence. CONCLUSIONS Previous conservative medical therapy bears the potential to modulate postoperative outcomes in HS patients, and should be taken into consideration. Despite reports of reliable results with split-thickness skin grafts, we found them to be associated with increased rates of diseases recurrence and postoperative complications.

Abstract
Hidradenitis suppurativa is a chronic, recurrent, autoinflammatory skin disease of the hair follicle and sebaceous glands in intertriginous skin areas. Treatment is based on clinical severity (typically classified according to Hurley stage). In advanced stages, radical excision of affected skin areas with secondary wound closure remains first-line treatment. Postoperative care in this setting should comprise nonadhesive wound dressings. The purpose of this article is to illustrate postoperative wound care after radical excision with secondary wound closure using nonadhesive, absorbent dressings for economical and effective care.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic immune-mediated inflammatory skin disease characterized by abscesses and inflammatory nodules, and occasionally tunnels and scars, in the axillae, groin, and inframammary areas. OBJECTIVE HS can be challenging to diagnose because it mimics localized soft-tissue infection. The process of differentiating HS from soft-tissue infection is discussed. Patients with HS frequently visit emergency departments (EDs) for acute management of pain and drainage from HS lesions. This review updates emergency and urgent care physicians on how to educate and initiate treatment for patients with HS, and to coordinate care with dermatologists and other physicians early in their disease course. DISCUSSION Recent updates on the epidemiology, diagnosis, and management of HS are reviewed. CONCLUSIONS Practice variations between how care for HS is provided in the ED setting and what HS treatment guidelines recommend are identified.

Abstract
Hidradenitis suppurativa is a chronic inflammatory condition that affects apocrine gland-bearing areas' causing abscesses and sinuses. Multimodality treatment is suggested for management. The surgical option is becoming more widely used, especially in drug-resistant cases. In this article, we describe a series of bilateral axillary hidradenitis cases which we treated with wide local excision and immediate reconstruction with lateral chest flap. Methods Fourteen patients presented to our clinic with bilateral hidradenitis suppurativa of the axilla. The cases were all resistant to medical treatment. They were managed by excision and simultaneous reconstruction with lateral chest flaps. Results At 3 months postoperatively, all patients had full shoulder range of motion and were completely satisfied with the aesthetic outcome, except for one patient who complained of the bulky look of his axilla. Liposuction was performed for him' with a pleasant resultant outcome. Conclusions Our patients underwent wide local excision of bilateral disease plus reconstruction with lateral chest flaps in the same session. Our aim was to introduce a treatment option for moderate to severe axillary hidradenitis suppurativa that offers good aesthetic and functional outcomes.

Abstract
Hidradenitis suppurativa (HS) is a chronic, inflammatory skin disease that is characterized by the formation of comedones, papules, nodules, abscesses and sinus tracts in the axillary, inframammary, groin, and gluteal areas. Up to 3.8% of the Canadian population has HS, though due to a lack of awareness of HS, many patients are initially misdiagnosed and do not receive adequate treatment early on in the disease course. Once a diagnosis of HS is made, developing an effective management plan can be a dilemma for many providers. There is significant variability in response to any given therapy within the HS patient population and many HS patients have other medical comorbidities which must be taken into consideration. The aim of this review is to provide a practical approach for all healthcare providers to diagnose and manage HS and its associated comorbidities. A sample electronic medical record template for HS management was developed by the Canadian Hidradenitis Suppurativa Foundation Executive Board and is intended for use in clinical settings. This will help to increase collaboration between primary healthcare providers, dermatologists, and other medical specialists and ultimately improve the quality of care that HS patients receive.

Abstract
Hidradenitis suppurativa (HS) is a chronic, inflammatory follicular disorder that most commonly involves the intertriginous areas. It is characterized by recurrent nodules that may progress into deeper abscesses and sinus tracts. Treatment is challenging and often involves a combination of lifestyle modifications, medical therapies, and procedures to control symptoms. Deroofing is a tissue-saving surgical technique that has been well studied in adults and in our clinical experience is an important adjunct therapy in pediatric patients with moderate-to-severe HS. We describe the step-by-step process of deroofing, including surgical clinical pearls specific to the pediatric population.

Abstract
Hidradenitis suppurativa (HS) is a chronic, progressive inflammatory disorder of follicular occlusion with pubertal onset that presents as painful inflammatory nodules, sinus tracts, and tunnelling in apocrine-gland-rich areas, such as the axilla, groin, lower back, and buttocks. The disease course is complicated by contractures, keloids, and immobility and is often associated with a low quality of life. It is considered a disorder of follicular occlusion with secondary inflammation, though the exact cause is not known. Management can often be unsatisfactory and challenging due to the chronic nature of the disease and its adverse impact on the quality of life. A multidisciplinary approach is key to prompt optimal disease control. The early stages can be managed with medical treatment, but the advanced stages most likely require surgical intervention. Various surgical options are available, depending upon disease severity and patient preference. In this review an evidence-based outline of surgical options for the treatment of HS are discussed. Case reports, case series, cohort studies, case-control studies, and Randomized Clinical Trials (RCT)s available in medical databases regarding surgical options used in the treatment of HS were considered for the review presented in a narrative manner in this article.

Abstract
Studies on hidradenitis suppurativa (HS) have found an increased prevalence of HS in skin of color and lower socioeconomic status patients, although the reasons for these differences are unclear. Demographic and therapeutic studies of HS originate primarily from developed Western countries, and data from low- and medium-income countries (LMIC) remain comparatively limited. In this review paper, we discuss differences in clinical presentation and comorbidities between racial and socioeconomic subpopulations and describe the genetic, biomedical, psychosocial, and ecological factors that may explain the associations between HS and skin of color and socioeconomic status. We highlight biomedical treatment considerations for LMIC including cost effective and less complex treatment strategies. We touch on population-based strategies to address the social determinants of health in HS management and discuss additional challenges arising from the COVID-19 pandemic.

Abstract
Hidradenitis suppurativa (HS) is an inflammatory disease of the skin with a chronic, relapsing-remitting course. The pathogenesis of the disease is poorly understood and involves multiple factors, including genetics, environment, host-microbe interactions, and immune dysregulation. In particular, the composition of the cutaneous microbiome shifts as the disease progresses, although it is unclear whether this is a primary or secondary process. Trials with immunomodulatory therapy elucidate the role of specific immune pathways and cytokine signaling in disease mechanism, such as TNF-α, IL-1β, IL-12, IL-17, IL-23, and complement. Future studies should continue examining the causes of and contributing factors to microbial changes and immune dysregulation in HS pathogenesis.

Abstract
Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by recurrent abscesses, nodules, and sinus tracts in areas of high hair follicle and sweat gland density. These sinus tracts can present with purulent drainage and scar formation. Dysregulation of multiple immune pathways drives the complexity of HS pathogenesis and may account for the heterogeneity of treatment response in HS patients. Using transcriptomic approaches, including single-cell sequencing and protein analysis, we here characterize the innate inflammatory landscape of HS lesions. We identified a shared upregulation of genes involved in interferon (IFN) and antimicrobial defense signaling through transcriptomic overlap analysis of differentially expressed genes (DEGs) in datasets from HS skin, diabetic foot ulcers (DFUs), and the inflammatory stage of normal healing wounds. Overlap analysis between HS- and DFU-specific DEGs revealed an enrichment of gene signatures associated with monocyte/macrophage functions. Single-cell RNA sequencing further revealed monocytes/macrophages with polarization toward a pro-inflammatory M1-like phenotype and increased effector function, including antiviral immunity, phagocytosis, respiratory burst, and antibody-dependent cellular cytotoxicity. Specifically, we identified the STAT1/IFN-signaling axis and the associated IFN-stimulated genes as central players in monocyte/macrophage dysregulation. Our data indicate that monocytes/macrophages are a potential pivotal player in HS pathogenesis and their pathways may serve as therapeutic targets and biomarkers in HS treatment.

Abstract
Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition that is more common in females, especially during puberty and menopause. These inflammatory lesions include painful deep-seated nodules and abscesses, draining sinus tracts, and fibrotic scars. This article is a narrative review to explain whole disease aspects, including complication, causes, epidemiology, history, classification, prognosis, comorbidities, the effect of sex hormone, and potent treatments. Most patients with HS, who are not aware of their primary disease, visit primary care physicians to superinfection lesions instead of specialists. If these physicians suspect HS, their illness will not get misdiagnosed. This brief and comprehensive information in this article may help doctors to decide better about the same situation.

Abstract
CME Dermatology 23: Hidradenitis suppurativa Abstract. Hidradenitis suppurativa (Acne inversa) is a chronic skin disease characterized by recurrent inflammatory nodules, abscesses, and scarring mainly in the intertriginous areas. The prevalence is estimated to be 0.05 to 4.1 % worldwide, with women being more commonly affected. The exact pathogenesis remains unknown, but hair follicle occlusion and inflammation seem to be the initiating events. Several epidemiological correlations with smoking and obesity as well as mutations in gamma secretase genes were described. The therapy depends on the extension of the disorder and should respect the current guidelines. Topical clindamycin is suitable for mild forms of the disease whereas moderate to severe disease requires systemic anti-inflammatory treatment. Surgical intervention is currently the only definitive treatment for hidradenitis suppurativa.

Abstract
The Fourth Annual Symposium on Hidradenitis Suppurativa (SHSA) took place on November 1-3, 2019, at the Westin Book Cadillac Hotel in Detroit, Michigan. This symposium was a joint meeting of the US Hidradenitis Suppurativa Foundation and the Canadian Hidradenitis Suppurativa Foundation. This cross-disciplinary meeting with experts from around the world was an opportunity to discuss the most recent advances in the study of hidradenitis suppurativa (HS) pathogenesis, clinical trials, classification, scoring systems, complementary/alternative medical treatments, diet, pain management, surgical and laser treatment, and ultrasonographic assessment. A special preconference workshop was held on the use of neodymium-doped yttrium-aluminum-garnet laser hair reduction, sinus tract deroofing, and carbon dioxide laser excision with ultrasonographic mapping and tumescent anesthesia for the treatment of HS. The focused workshops on establishing an HS clinic, setting up an HS support group, the Hidradenitis Suppurativa Prospective Observational Registry and Biospecimen Repository, and wound care were held during the meeting. A special program called HS Ambassadors was established for patients who may have questions about the conference presentations, and in addition, a meet and greet for patients and HS Ambassadors was arranged. To facilitate networking between those early in their careers and clinical and research experts, a mentoring reception was held.

Office-Based Surgical Intervention for Hidradenitis Suppurativa (HS): A Focused Review for Dermatologists. Dermatol Ther (Heidelb) 2020; 10:529-549.

Abstract
Easily accessible office-based procedures that require minimal resources may facilitate timely surgical management of hidradenitis suppurativa (HS). This review focuses on excision and unroofing as two surgical HS treatments that can be tailored to the outpatient setting. Fifty-five articles were included in our review, representing 3914 patients. The majority were retrospective studies (58%, n = 32), and the studies reported data both across patients and by number of treated lesions. Recurrence rates for unroofing (14.5%) were found to be half that of excision (30%) across patients (p = 0.015) and slightly lower across lesions [20% recurrence vs 26% for excision (p = 0.023)]. Complication rates at the lesion level were also significantly associated with procedure, with rates after excision more than double those after roofing (26% vs. 12%, p < 0.001). The complication rate after combined medical and surgical therapy did not differ between procedures. Studies also suggest that continuing medical therapy in the perioperative period may be associated with improved recurrence rates, although delayed wound healing with biologic therapy has been reported. The existing data are limited by low-quality uncontrolled studies with small sample sizes, variable reporting of outcomes, and lack of uniform definitions for recurrence and remission. Further systematic prospective studies are needed to better compare complication and recurrence rates across these procedures in HS, especially in the context of concomitant medical therapy.

Abstract
Background Hidradenitis suppurativa (HS) is a chronic inflammatory disorder. Several medical treatments, with varying degrees of efficacy, have been developed. However, in most cases of advanced HS, the definitive treatment option is often represented by surgical excisions. Objective Surgical techniques, reconstructive approach, and local wound care should be accurately designed in order to obtain the best result. In this review we analyze the possible surgical treatments and local wound care. Methods A MEDLINE search was performed on the various surgical treatments, reconstructive techniques, and local wound care. Results Surgical treatment is a common therapeutic modality for HS. Different surgical reconstructive techniques and post-surgical wound care approaches are described for the management of HS patients. Conclusions There were few high-quality evidence-based studies evaluating the surgical management of HS. Many disparate HS severity scores were used in these studies, making comparisons between them difficult. Nonetheless, research on different surgical approaches and wound care management has increased substantially in the past decade and it has given patients more surgical therapeutic strategies. The description of the best combinations and timing of surgery, wound care, and medical therapies will be a matter of future research for the definition of the optimal management of the HS patient.

Abstract
Hidradenitis suppurativa (HS) is a chronic, often debilitating, skin condition that historically does not respond well to treatment. Although there is no cure for HS, symptoms can be managed if the appropriate diagnosis is made. HS most commonly develops in postpubertal women and manifests as painful, deep-seated, inflamed lesions, including nodules, sinus tracts, and abscesses. HS flares are marked by increased pain and suppuration at varying intervals and can occur in women before menstruation. HS is commonly misdiagnosed; physicians might mistake a lesion for an infection, abscess, or sexually transmitted infection. Incision and drainage of these lesions often leads to recurrence. Given that management of this chronic disease is often difficult, we sought to outline current diagnosis and management strategies for HS.

Abstract
Background Hidradenitis suppurativa (HS) is a chronic debilitating folliculopilosebaceous disease that affects the skin most commonly in the axilla, groin, inframammary, genital and buttock areas. Surgical intervention may be an appropriate option in selected cases, but there is a risk of recurrence. The purpose of this study was to assess the results of wide local excision (WLE) to healthy subcutaneous fat with secondary intention healing in patients with HS who were under concurrent surgical and dermatologic care. Methods We conducted a retrospective review of 192 consecutive HS consultations to a general surgical service, identifying patients treated with WLE. Cases involving minor procedures (deroofing, incision and drainage) were excluded. Data on patient demographics, surgical site, method of closure, complications and recurrence were extracted from patient charts. We also conducted a literature review of surgical procedures in the management of HS. Results A total of 66 patients underwent 133 WLE to healthy subcutaneous fat. All patients were under concurrent medical care directed by a dermatologist. No medical therapies, including biological treatments, were interrupted or withheld for surgery. One hundred procedures were closed primarily with rotation or advancement flaps and 33 by secondary intention healing. Local recurrence occurred in 18% of primary closures and 18% of secondary intention closures (p = 0.98, χ2 test, no difference between groups). One patient with secondary intention healing returned to the emergency department for bleeding; 34% of patients with primary closure experienced some dehiscence (23% major, 11% minor separation). Two patients with axillary disease had restrictions in their ability to raise their arm that required physiotherapy. Median follow-up was 14.5 (range 1–55) months. Conclusion Resection to healthy subcutaneous fat during WLE provides disease control comparable to that with deeper resections, simplifying care.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic debilitating condition. Treatment of HS depends on disease stage, goals of care, access to care, and frequency of symptoms. We present our experience with surgical treatment for patients with HS. METHODS Patients were followed longitudinally for at least 2 years postsurgical intervention. Demographic data, participation in a multidisciplinary program, type of surgery, healing rates, and potential factors contributing to wound healing were retrospectively reviewed in all cases using multivariate analysis. RESULTS Two hundred forty-eight patients met the inclusion criteria with a total of 810 involved sites. Overall, 59% of patients had Hurley stage 3 disease at the time of surgery. Healing rates of 80% were observed in stages 1 and 2, and 74% were observed in stage 3. Hurley stage was not a significant predictor of healing (P = 0.09). Surgical treatment consisted of 38% incision and drainage, 44% excision without closure, and 17% excision with primary closure. Incisional and excisional treatments healed 78% and 79%, respectively, at 2 years. Primarily repaired defects (grafts and flaps) were 68% healed at 2 years. Observed healing rates were uniform regardless of the number of sites involved (P = 0.959). Participation in the multidisciplinary program was the strongest predictor of healing (78% vs 45%, P = 0.004). Sex, age, body mass index, tobacco use, diabetes, presurgery hemoglobin, and family history of HS were statistically not significant. Continuation of immune modulating therapy within 2 weeks of surgery was a predictor of reduced healing (odds ratio, 0.23; P = 0.004), whereas holding biologics for at least 2 weeks was not significant (odds ratio, 1.99; P = 0.146). CONCLUSIONS Participation in a multidisciplinary program is a strong predictor of long-term success when treating HS. Hurley score and number of involved sites did not correlate with successful healing after surgery. If taking biologics, we identified 2 weeks as an appropriate break from biologics before and after surgical intervention. Healing rates were highest with ablative procedures (incision and drainage, excision) alone.

Abstract
BACKGROUND AND OBJECTIVES Deroofing has proven to be an effective method to treat mild to moderate forms of hidradenitis suppurativa (HS). The basic procedure includes removal of the sinus roof, followed by secondary intention healing, while fibrotic tissue usually stays in situ. We have tried to establish a modified method of deroofing in which meticulous removal of the fibrotic tissue results in a low recurrence rate in moderate to severe HS patients. PATIENTS AND METHODS An open prospective study consisted of 96 deroofed lesions in 52 consecutive patients with moderate to severe HS. Patients were followed up for a minimum of 28 months. RESULTS Recurrence occurred after a median time of 2.3 months in 14 % of locations. Recurrences according to location were as follows: 6 % in the axillary region and 25 % in the inguinal region. Postoperative bleeding was the only considerable complication and occurred in 7 % of treated locations. Seven patients were lost to follow-up. CONCLUSION Modified deroofing followed by meticulous sinus tract removal is a surgical approach suitable for patients with moderate disease, especially in the axillary region. This results in a low recurrence rate and the same healing period as that of the standard deroofing procedure.

Abstract
Hidradenitis suppurativa/acne inversa (HS/AI) is a chronic inflammatory skin disease. Therapy consists of conservative and surgical treatment options. In Hurley stages II and III, surgical intervention is regarded as the method of choice for areas with irreversible tissue destruction. Resection techniques with different grades of invasiveness are described in the literature. Nevertheless, there is no generally accepted concept regarding resection and reconstruction techniques or specific postoperative care. Due to lack of definitions of recurrence after surgery and poor study quality, recurrence rates are difficult to determine.

Abstract
Hidradenitis suppurativa (HS)/acne inversa is a debilitating chronic disease that remains poorly understood and difficult to manage. Clinical practice is variable, and there is a need for international, evidence‐based and easily applicable consensus on HS management. We report here the findings of a systematic literature review, which were subsequently used as a basis for the development of international consensus recommendations for the management of patients with HS. A systematic literature review was performed for each of nine clinical questions in HS (defined by an expert steering committee), covering comorbidity assessment, therapy (medical, surgical and combinations) and response to treatment. Included articles underwent data extraction and were graded according to the Oxford Centre for Evidence‐based Medicine criteria. Evidence‐based recommendations were then drafted, refined and voted upon, using a modified Delphi process. Overall, 5310 articles were screened, 171 articles were analysed, and 65 were used to derive recommendations. These articles included six randomized controlled trials plus cohort studies and case series. The highest level of evidence concerned dosing recommendations for topical clindamycin in mild disease (with systemic tetracyclines for more frequent/widespread lesions) and biologic therapy (especially adalimumab) as second‐line agents (following conventional therapy failure). Good‐quality evidence was available for the hidradenitis suppurativa clinical response (HiSCR) as a dichotomous outcome measure in inflammatory areas under treatment. Lower‐level evidence supported recommendations for topical triclosan and oral zinc in mild‐to‐moderate HS, systemic clindamycin and rifampicin in moderate HS and intravenous ertapenem in selected patients with more severe disease. Intralesional or systemic steroids may also be considered. Local surgical excision is suggested for mild‐to‐moderate HS, with wide excision for more extensive disease. Despite a paucity of good‐quality data on management decisions in HS, this systematic review has enabled the development of robust and easily applicable clinical recommendations for international physicians based on graded evidence.

Abstract
Hidradenitis suppurativa (HS) is a chronic, recurrent, inflammatory disease of apocrine gland-bearing skin which affects approximately 1-4% of the population. Defective keratinocyte function has been postulated to play a role in HS pathogenesis. Using an in vitro scratch assay, differences between normal, HS, and chronic wound (CW) keratinocytes were evaluated. Normal keratinocytes exhibited faster scratch closure than HS or CW, with normal samples showing 93.8% closure at 96 hours compared to 80.8% in HS (p = 0.016) and 71.5% in CW (p = 0.0012). The keratinocyte viability was similar in normal and HS (91.12 ± 6.03% and 86.55 ± 3.28%, respectively, p = 0.1583), but reduced in CW (72.34 ± 13.12%, p = 0.0138). Furthermore, apoptosis measured by annexin V/propidium iodide, was higher in CW keratinocytes (32.10 ± 7.29% double negative cells compared to 68.67 ± 10.37% in normal and 55.10 ± 9.46% in HS, p = 0.0075). Normal keratinocytes exhibited a significantly higher level of IL-1α (352.83 ± 42.79 pg/ml) compared to HS (169.96 ± 61.62 pg/ml) and CW (128.23 ± 96.61 pg/ml, p = 0.004). HS keratinocytes exhibited significantly lower amounts of IL-22 (8.01 pg/ml) compared to normal (30.24 ± 10.09 pg/ml) and CW (22.20 ± 4.33 pg/ml, p = 0.0008), suggesting that defects in IL-22 signaling may play a role in HS pathogenesis. These findings support intrinsic differences in keratinocyte function in HS which cannot be attributed to reduced keratinocyte viability or increased apoptosis.

Abstract
BACKGROUND Hidradenitis supppurativa (HS) is a chronic inflammatory disease of the apocrine sweat glands affecting 1-4% of the population. While surgical excision is a mainstay of therapy, lesions often recur. Biologic therapies, including tumor necrosis factor-α and IL-12/23 inhibitors, are effective for mild to moderate HS. However, longitudinal studies investigating biologic therapy in conjunction with surgery are limited. The purpose of this analysis was to investigate impact of surgery and biologic therapy on HS disease activity. METHODS Data from 68 HS patients were analyzed. Outcome measures included hidradenitis suppurativa Sartorius Score (HSS), active nodule (AN) count, Hurley stage, and probability of achieving 75% reduction in active nodule count (AN75). RESULTS Mean age was 40 ± 14 years; 66% were female and 72% were African American. Mean disease duration was 10 years, and Hurley stage III disease was seen in 63% of patients. Patients who received biologics had a larger drop in HSS and AN count than those who never received biologics (P = 0.002). Biologic treatment was associated with average reduction in 22 (15-29) HSS points (P < 0.0001). The effect of biologics was greater in patients who also underwent surgery (P = 0.013). Timing of biologics relative to surgery did not impact efficacy. Patients who received HS surgery with biologic therapy were most likely to achieve the AN75 (P = 0.017). CONCLUSIONS In this diverse cohort of patients with severe HS, biologic therapy was associated with a more rapid decline in disease activity, with the greatest effect in patients who also underwent HS surgery.

Abstract
Hidradenitis suppurativa (HS) is a chronic, recurrent, inflammatory disease of apocrine gland-bearing skin which affects approximately 1–4% of the population. The disease is more common in women and patients of African American descent and approximately one-third of patients report a family history. Obesity and smoking are known risk factors, but associations with other immune disorders, especially inflammatory bowel disease, are also recognized. The pathogenesis of HS is poorly understood and host innate or adaptive immune response, defective keratinocyte function, and the microbial environment in the hair follicle and apocrine gland have all been postulated to play a role in disease activity. While surgical interventions can be helpful to reduce disease burden, there is a high recurrence rate. Increasingly, data supports targeted immune therapy for HS, and longitudinal studies suggest benefit from these agents, both when used alone and as an adjunct to surgical treatments. The purpose of this review is to outline the current data supporting use of targeted immune therapy in HS management.

Abstract
Hidradenitis suppurativa (HS) is a devastating disease involving abscesses, sinus tracts, and inflammation classically affecting the axilla, groin, and/or anogenital region. Although the disease pathogenesis is not fully understood, recent advances suggest that HS pathology runs much deeper than the cutaneous manifestations. It is now believed that HS is a systemic inflammatory disease that gives rise to the characteristic cutaneous manifestations. This disease is problematic for both patients and physicians to manage because of a variety of diagnostic and management difficulties. This article seeks to provide updates on the current understanding of HS to increase awareness and improve management.

Abstract
Hidradenitis suppurativa (HS) is a debilitating suppurative disease of the apocrine/follicular glands. Medical treatment has some efficacy in early-stage disease but is costly and requires frequent physician visits. Advanced disease usually requires surgical intervention. This treatment has not been well described in the literature. We sought to review our experience with HS treatment in a large surgical cohort. A retrospective review of 98 consecutive HS patients from 2000 to 2014 was performed. A two-stage operative approach was used. The first stage involved the removal of all the hair-bearing skin in the affected areas down to healthy tissue followed by the application of split-thickness skin grafts 48 to 72 hours later. Descriptive statistics were performed to describe the population and assess outcomes. The study population was young (36 ± 12 years) and predominately female (65, 66%). The patients were obese (body mass index, 36 ± 8.3 kg/m) and smokers (73, 73.7%). The majority presented with axillary disease (73%). There were 144 debridement procedures and 146 grafting procedures performed with a mean area grafted being 416 ± 500 cm (90-3400 cm). Only nine (9%) required regrafting, with the mean area regrafted being 140 ± 93 cm. Graft failure of less than 30% did not require regrafting. At 30 days after the initial procedure, 94.7% of all wounds were fully grafted and closed. Advanced stages of HS require ablation of the infected distorted glands for control of recurrent infections. Ablative excision of HS-affected skin and wound closure with split-thickness skin grafts is a safe, reliable, and effective therapy.
