Environmental and occupational risk...Hidradenitis suppurativa (HS) is a chronic, inflammatory skin condition characterized by painful nodules, abscesses, and scarring, primarily affecting areas rich in apocrine glands. Environmental and occupational risk factors, including prolonged exposure to heat, friction, and certain chemicals, have been identified as exacerbating conditions for HS. Yet, there remains a lack of tailored recommendations for modifying work environments to alleviate these triggers. This review presents novel suggestions for work modifications to reduce HS flare-ups, such as implementing breathable, friction-reducing workwear, ergonomic adjustments to minimize pressure on affected areas, and introducing low-irritant hygiene protocols in workplaces with chemical exposure. These recommendations are grounded in emerging evidence linking specific occupational exposures to the exacerbation of HS symptoms. The novelty of this approach lies in its proactive stance, shifting from reactive management of HS symptoms to preventative environmental modifications. Future studies should explore the long-term efficacy of these modifications and investigate the potential for personalized work environment adjustments based on individual patient profiles. Targeted workplace interventions may significantly improve the quality of life for HS patients, highlighting the need for multidisciplinary collaboration between dermatologists, occupational health specialists, and employers.展开更多

Furthermore, NASH is the more aggressive necro-inflammatory form, which may accumulate fibrosis and result in End stage liver disease(ESLD). NAFLD is also linked to systemic inflammatory conditions such as psoriasis. NAFLD is currently the most common cause of ESLD in Western countries, becoming a serious public health concern.Hidradenitis suppurativa(HS) is a systemic inflammatory/autoinflammatory disease of the terminal follicular epithelium of the apocrine gland with a prevalence of 0.05% to 4.10%. Due to its systemic inflammatory behavior several comorbidities were recently associated, however liver ones were scarcely assessed.AIM To evaluate the prevalence and characteristics of NASH/NAFL in HS patients.METHODS This retrospective study is a sub-analysis of a larger study carried out in 4 Italian dermatological centers. In this cohort, there were 83 patients: 51 patients with HS only, 20 patients with HS/NAFL and 12 with HS/NASH.RESULTS Inflammatory comorbidities were present in 3.9% of HS only patients, 25% of HS/NAFL patients and 58.3% of HS/NASH patients(P < 0.001). Similarly, mean Autoinflammatory Disease Damage Index(ADDI) was significantly higher among patients with HS/NASH(5.3 ± 2.2, P < 0.001) compared to patients with HS/NAFL or HS only(2.8 ± 1.6 and 2.6 ± 1.4 respectively). Furthermore, ADDI correlates with IHS4 in HS, HS/NAFL and HS/NASH. Diabetic patients have higher Hurley score than not diabetic ones. Ultrasound examination was significantly different in the three groups.CONCLUSION HS patients displayed a high prevalence of NASH/NAFLD and ultrasound examination should be particularly addressed to patients that display high ADDI scores.展开更多

Axillary, inframammary, intermammary, and peri-areolar apocrine gland involvement may be visualized mammographically. Characteristic lesions tend to be round or oval, lucent, and smooth-bordered, with or without central densities. While diagnosis made purely via mammography is unlikely, having an awareness of this entity may prove useful in patient care in regards to proper utilization of both imaging and consultative resources.展开更多

It is often chronic, painful, disabling, and can worsen over time. Besides surgically excising affected areas, effective treatments are currently lacking. The long-pulsed neodymium:yttrium-aluminium-garnet (Nd:YAG) laser is a device that has traditionally been used for hair removal, but has recently shown promise in clearing old lesions of HS and preventing new eruptions. In accordance with studies in the current literature, we hypothesize that the Nd:YAG laser will significantly improve subjects with hidradenitis suppurativa compared to standard, uninvasive treatment with topical antibiotics [1,2]. Study aims include: to treat subjects with hidradenitis suppurativa with Nd:YAG laser therapy once monthly for 3 consecutive months, with a one month follow-up;to compare the effectiveness of Nd:YAG treatment on one side of the subject (e.g., right) to treatment with topical antibiotics on the subject’s other side (e.g., left);to assess treatment response using a visual analogue scale;to assess subject satisfaction with treatment using a questionnaire;and to photodocument treatment response at each visit.展开更多

Familial AI shows autosomal-dominant inheritance caused by mutations in the γ-secretase genes. This study was aimed to identify the specific mutations in the y-secretase genes in two Chinese families with AI. Methods： In this study, two Chinese families with AI were investigated. All the affected individuals in the two families mainly manifested with inultiple comedones, pitted scars, and a few inflammatory nodules on their face, neck, trunk, axilla, buttocks, upper arms, and thighs. Reticulate pigmentation in the flexures areas resembled Dowling-Degos disease clinically and pathologically. In addition, one of the affected individuals developed anal canal squamous cell carcinoma. Molecular mutation analysis of γ-secretase genes including PSENEN, PSENI, and NCSTN was performed by polymerase chain reaction and direct DNA sequencing. Results： Two novel mutations of PSENEN gene were identified, including a heterozygous missense mutation c. 194T〉G （p.L65R） and a splice site mutation c. 167-2A〉G. Conclusions： The identification of the two mutations could expand the spectrum of mutations in the γ-secretase genes underlying AI and provide valuable information for further study of genotype-phenotype correlations.展开更多

文摘Hidradenitis suppurativa is a chronic suppurative inflammation of the apocrine sweat glands. Axillary, inframammary, intermammary, and peri-areolar apocrine gland involvement may be visualized mammographically. Characteristic lesions tend to be round or oval, lucent, and smooth-bordered, with or without central densities. While diagnosis made purely via mammography is unlikely, having an awareness of this entity may prove useful in patient care in regards to proper utilization of both imaging and consultative resources.

文摘Hidradenitis suppurativa(HS)is a chronic,inflammatory skin condition that poses a significant diagnostic and therapeutic challenge for clinicians,as the underlying etiology and pathogenesis remains unclear.The host of genetic mutations and immune dysfunction has been identified to be involved in the pathogenesis of HS during recent years.These genetic defects,including monogenetic mutations altering subunits ofγ-secretase,a protease that functions through Notch signaling to maintain skin appendages,promote epithelial stability,suppress/terminate innate immune responses(ie,Toll-receptors),further have the propensity to induce aberrant cytokine responses that create to a proinflammatory environment,consequently induce hyperkeratosis and promote expression of pro-inflammatory,locally destructive matrix metalloproteinases.Cytokine-driven inflammation propagates the disease state of HS and contributes to the formation of painful subcutaneous nodules,abscesses,and eventually,fistulas and draining sinus tracts.A closer look at genetic mutations linked to the disease may explain the immune perturbations seen in HS.An understanding of the immune cells and inflammatory markers expressed in affected individuals provides insight into disease pathogenesis and can help identify therapeutic targets.

文摘Objective:This study was performed to estimate the prevalence of hidradenitis suppurativa(HS)in China and describe the demographic and clinical features of HS in the Chinese population.Methods:This multicenter clinic-based cross-sectional study was conducted in dermatology clinics within 19 hospitals located in 15 cities/provinces across China from September to October 2020.The prevalence of HS was calculated as the percentage of patients with HS among all visitors at participating clinics during the 1-month study period.HS was independently diagnosed by two certified dermatologists at each site.All visitors at participating clinics were screened,and all patients with HS were invited to participate in a questionnaire survey to elucidate the demographics and clinical features of HS in the Chinese population.Results:We identified 92 patients with HS among 274,742 visitors at participating clinics.The prevalence rate was 0.03349%or 33.49 per 100,000 population(95%confidence interval,26.64–40.32),and the female:male ratio was 1.0:4.7.Conclusion:The overall prevalence of HS in China was lower than that in Western and other Asian countries with a predominance of male patients.
文摘Acne inversa/hidradenitis suppurativa is a chronic,recurrent,inflammatory skin disease that affects the pilosebaceous units,causinfollicular occlusion.The etiology and pathogenesis of acne inversa/hidradenitis suppurativa involves internal and external factors such as genetic susceptibility,inflammation and immunity,microorganisms,obesity,and smoking.acne inversa/hidradenitis suppurativa is difficult to treat,and the current aim of treatment is to control the frequency and duration of disease flares and improve the quality of life.Treatment protocols for acne inversa/hidradenitis suppurativa should be selected based on the disease severity grade.Medical treatments include antibiotics,retinoids,biologics,immunosuppressive agents,and antiandrogen agents.Adjuvant treatments include surgery and laser/light therapies.This consensus aims to further standardize the diagnosis and treatment procedures of acne inversa/hidradenitis suppurativa in China to facilitate its diagnosis and treatment.
文摘Objective The results of association studies between hidradenitis suppurativa and diabetes mellitus remain controversial.This study aimed to investigate the association between hidradenitis suppurativa and diabetes mellitus by reviewing all the available evidences comprehensively.Methods We performed a meta-analysis on observational studies that reported the odds ratio (OR) comparing diabetes mellitus risk in patients with hidradenitis suppurativa versus participants without hidradenitis suppurativa.Pooled OR and 95％ confidence intervals (95％CIs) were calculated using a random effect,generic inverse variance methods of DerSimonian and Laird.Results Four studies (two cross-sectional studies and two case-control studies) including 5,362 patients with hidradenitis suppurativa and 23,193participants without hidradenitis suppurativa were identified and coved in the meta-analysis.The pooled OR of diabetes mellitus in patients with hidradenitis suppurativa was 1.95 (95％CI:1.31-2.91).The statistical heterogeneity of this meta-analysis was I2 =63％.Conclusions This meta-analysis shows a signi ficant risk increase of diabetes mellitus incidence among patients with hidradenitis suppurativa.Patients with hidradenitis suppurativa should be regularly screened for diabetes mellitus as complication.

文摘Background： Acne inversa （AI）, also called hidradenitis suppurativa, is a chronic, inflammatory, recurrent skin disease of the hair follicle. Familial AI shows autosomal-dominant inheritance caused by mutations in the γ-secretase genes. This study was aimed to identify the specific mutations in the y-secretase genes in two Chinese families with AI. Methods： In this study, two Chinese families with AI were investigated. All the affected individuals in the two families mainly manifested with inultiple comedones, pitted scars, and a few inflammatory nodules on their face, neck, trunk, axilla, buttocks, upper arms, and thighs. Reticulate pigmentation in the flexures areas resembled Dowling-Degos disease clinically and pathologically. In addition, one of the affected individuals developed anal canal squamous cell carcinoma. Molecular mutation analysis of γ-secretase genes including PSENEN, PSENI, and NCSTN was performed by polymerase chain reaction and direct DNA sequencing. Results： Two novel mutations of PSENEN gene were identified, including a heterozygous missense mutation c. 194T〉G （p.L65R） and a splice site mutation c. 167-2A〉G. Conclusions： The identification of the two mutations could expand the spectrum of mutations in the γ-secretase genes underlying AI and provide valuable information for further study of genotype-phenotype correlations.
文摘Background:Male genital form and function may be rendered abnormal by a number of disease processes,with profound associated psychological and functional consequences.The aim of the study is to review our reconstructive experience with cases of genital loss or distortion due to nonmalignant diseases processes and atypical neoplasia.Materials and methods:A retrospective review of a prospectively maintained database was performed to identify reconstructive cases performed from 2018 to 2020 under the care of a single surgeon.Male patients 18 years or older with a disease diagnosis other than squamous cell carcinoma affecting genital form were included.Disease processes,patient factors,surgical techniques,and both functional and cosmetic outcomes were reviewed.Results:Fourteen cases were identified.The patients had a mean age of 52.2 years(range,21-72 years).Acquired buried penis was present in 8 patients.Etiology of genital abnormality included balanitis xerotica obliterans(n=6),excess skin loss at circumcision(n=2),self-injection of petroleum jelly to penile shaft(n=1),Fournier gangrene(n=1),hidradenitis suppurativa(n=1),extramammary Paget disease(n=1),idiopathic lymphoedema(n=1),and penoscrotal webbing(n=1).Reconstructive techniques performed included penile debridement/shaft skin release,scrotectomy,suprapubic apronectomy,and division of penoscrotal webbing,in combination with split-thickness skin grafting where required.A penile implant was inserted in one patient.Reconstructive planning,techniques,and outcomes are described.Conclusions:A variety of reconstructive techniques in andrology can be used to improve the aesthetic and functional outcomes of multiple disease processes affecting the male external genitalia.
