Tumor necrosis factor-α inhibitor treatment of acne fulminans - a clinical and literature review.

Acne fulminans (AF) is a rare, serious, sudden-onset and long-lasting skin disease that causes scarring of face and body. Standard treatment with combined long-term isotretinoin and prednisolone is not always sufficient and has a well-known propensity for adverse effects leaving an unmet need for improved therapy. Case reports suggest that tumor necrosis factor (TNF)-α inhibitors may play a role in the management of AF. In a 3-year retrospective data collection from two dermatology centers and literature review of clinical cases of acne fulminans treated with anti-TNF-α therapy, three clinical cases and twelve literature cases were identified. A total of five different TNF-α inhibitors have been tested, with adalimumab being the most commonly used. Clinical response was seen after 1 month in 2/3 (67%) clinical cases and 5/12 (42%) literature cases, respectively, and treatment was successful in 2/3 (67%) and 11/12 (92%) after a median 3-7 months. All reported adverse effects were mild and reversible. Anti-TNF-α treatment may provide rapid improvement in patients with AF when initial treatment with isotretinoin and prednisolone fails. However, randomized controlled trials are lacking, and exact dosage and timing need to be explored before clinical implementation.

Laser and intense pulsed light in the treatment of hidradenitis suppurativa.

Treatment of hidradenitis suppurativa (HS) requires a combination of medical, surgical, and lifestyle interventions. Intense pulsed light (IPL) and lasers have been reported to be useful. The aim of this review is to find the evidence supporting IPL and laser treatment of HS and to provide guidance for the management of specific HS lesions. We searched PubMed and Web of Science for "laser" and "hidradenitis suppurativa" on April 6, 2022. Inclusion criteria were >10 patients, reported follow-up, English language, and human subjects with a diagnosis of HS. A total of 724 articles were screened, but only 17 studies qualified for inclusion (IPL (n = 4), Nd:YAG (n = 6), CO2 laser (n = 6), and intralesional treatment (n = 2). The majority of the studies had a low (n = 10) or moderate (n = 7) evidence level. Treatment effect was noticed in studies using IPL and Nd:YAG (hair reduction). CO2 laser was used for surgery with a success rate ranging from 70.7% to 96.7%. CO2 laser is useful for surgery of stationary HS lesions, but it is difficult to draw a conclusion on the use of IPL and Nd:YAG (hair reduction) as the studies were too heterogeneous to perform a meta-analysis.

Symptoms of attention deficit hyperactivity disorder are associated with Hidradenitis suppurativa in Danish blood donors.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease associated with psychiatric comorbidity. Attention deficit hyperactivity disorder (ADHD) is a mental disorder associated with systemic and skin inflammation such as psoriasis and atopic dermatitis. Whether HS symptoms are associated with ADHD symptoms remains unexplored. Thus, the aim of this study was to explore the possible association between HS and ADHD. Participants in the Danish Blood Donor Study (DBDS) were included in this cross-sectional study during 2015-2017. The participants provided questionnaire data on screening items of HS, ADHD symptoms (ASRS-score), and depressive symptoms, smoking and body mass index (BMI). A logistic regression with HS symptoms as a binary outcome predicted by ADHD adjusted for age, sex, smoking, BMI, and depression was conducted to investigate the association between HS and ADHD. A total of 52,909 Danish blood donors were included in the study. Of these were 1004/52,909 (1.9%) considered participants with HS. Of the participants with HS, 74/996 (7.4%) screened positive of ADHD symptoms, while only 1786/51,129 (3.5%) of the participants without HS screened positive of ADHD. Adjusted for confounders, ADHD was positively associated with HS, odds ratio 1.85 (95% confidence interval: 1.43-2.37). Psychiatric comorbidity of HS is not limited to depression and anxiety. This study shows a positive association between HS and ADHD. Further research on the biological mechanisms behind this association is warranted.

Clinical characteristics of pediatric hidradenitis suppurativa: a cross-sectional multicenter study of 140 patients.

Hidradenitis suppurativa (HS) rarely affects pediatric patients. The literature on pediatric HS patients is scarce. This is a cross-sectional study based on case note review or interviews and clinical examination of 140 pediatric patients undergoing secondary or tertiary level care. Patients were predominantly female (75.5%, n = 105) with a median age of 16. 39% reported 1st-degree relative with HS. Median BMI percentile was 88, and 11% were smokers (n = 15). Median modified Sartorius score was 8.5. Notable comorbidities found were acne (32.8%, n = 45), hirsutism (19.3%, n = 27), and pilonidal cysts (16.4%, n = 23). Resorcinol (n = 27) and clindamycin (n = 25) were the most frequently used topical treatments. Patients were treated with tetracycline (n = 32), or oral clindamycin and rifampicin in combination (n = 29). Surgical excision was performed in 18 patients, deroofing in five and incision in seven patients. Obesity seemed to be prominent in the pediatric population and correlated to parent BMI, suggesting a potential for preventive measures for the family. Disease management appeared to be similar to that of adult HS, bearing in mind that the younger the patient, the milder the disease in majority of cases.

Systematic Review of Complications and Recurrences After Surgical Interventions in Hidradenitis Suppurativa.

BACKGROUND: The possible connection between hidradenitis suppurativa (HS) patients undergoing surgery and higher complications/recurrences has been implied, but inconsistent results reported. OBJECTIVE: To assess the complication and recurrence rates for HS patients undergoing surgery and to evaluate whether known HS comorbidities and habits (smoking, obesity and diabetes) have an effect on the complication and recurrence rates. MATERIALS AND METHODS: A systematic review was conducted by 2 reviewers. PubMed and Embase were searched using a predefined search string created in collaboration between the authors and a librarian on January 23, 2019. RESULTS: Of the 271 references in the original search, 54 relevant articles were identified. This systematic review indicates an overall mean complication rate of 24% and a mean recurrence rate of 20.1% for HS patients undergoing surgery. CONCLUSION: No significant association between the known surgical risk factors and surgical complications-or recurrence rates in this patient group was found. This review revealed a lack of quality and quantity data in studying the complications/recurrences. The heterogeneity of the studies created limitations, and the presented mean complication/recurrence rates should be interpreted with the consequences thereof. It elucidates the need for better studies and a necessity for a standardized definition of postsurgical HS recurrence.

Concomitant Hidradenitis Suppurativa and Eruptive Xanthomas Presenting with Phimosis - The Importance of Timely Diagnosis.

A 49-year-old man diagnosed with metabolic syndrome (MetS) was referred to us for treatment of xanthoma elements. Physical examination revealed widespread confluent yellow firm papules on his fingers, toes, arms, legs, and back. The diagnosis of eruptive xanthoma (EX) was clinically confirmed. During the examination of scar tissues, tombstone comedones and an inflammatory nodule was noted on his abdominal folds and right groin. These are diagnostic signs of hidradenitis suppurativa (HS), a condition the patient had reportedly suffered for 15 years without being diagnosed. The patient's HS nodule was treated with intralesional triamcinolone injection, and prophylactic resorcinol was initiated, and he was referred to endocrinologists for xanthoma management. Three weeks later he returned due to newly developed lesions on his preputium, which caused a painful phimosis. Both HS and EX are correlated with MetS and causes increased all-cause cardiovascular mortality. As the average diagnostic delay of HS is 7.2 years, it is likely that timely diagnosis of HS would have identified the patient as being at risk of developing MetS. With proper preventive measures, the resulting EX lesions and increase in cardiac mortality could have been avoided.

Hidradenitis Suppurativa: Advances in Diagnosis and Treatment.

IMPORTANCE: Hidradenitis suppurativa (HS) is relatively common, with the prevalence of 0.05% to 4.10%, yet many patients receive inadequate treatment. OBJECTIVE: To review the diagnosis, epidemiology, and treatment of HS with an emphasis on advances in the last 5 years. EVIDENCE REVIEW: A literature search was conducted using PubMed, MEDLINE (Medical Subject Headings [MeSH]), and EMBASE to include recently published treatment studies (searched from September 1, 2011, to May 1, 2017). Reviews, guidelines, conference abstracts, and studies with less than 10 patients were excluded. Furthermore, internet searches for guidelines on hidradenitis suppurativa using Baidu, Bing, Google, and Qwant browsers were performed. FINDINGS: The diagnosis of HS is made by lesion morphology (nodules, abscesses, tunnels, and scars), location (axillae, inframammary folds, groin, perigenital, or perineal), and lesion progression (2 recurrences within 6 months or chronic or persistent lesions for ≥3 months). HS is more common than was previously thought based on epidemiological analysis (0.05%-4.10%). Disability from HS can be significant. Patients with HS may have significant comorbidities (eg, obesity, metabolic syndrome, diabetes, and arthritis) and increased all-cause mortality (incidence rate ratio, 1.35 [95% CI, 1.15-1.59]). Antibiotic treatment with combinations of clindamycin and rifampicin, or ertapenem followed by combination rifampicin, moxifloxacin, and metronidazole for 6 months is effective. Adalimumab is effective in a significant proportion of patients and treatment with IL-1 and IL-12 receptor subunit beta 1 (Rb1) antibodies may also be useful. Tissue-sparing surgical techniques and carbon dioxide laser treatments also are available, but the evidence on clinical outcomes with these approaches is limited. CONCLUSIONS AND RELEVANCE: Hidradenitis suppurativa is more common than previously thought and may be treated by an array of pharmacological and surgical techniques. Hidradenitis suppurativa should be considered in the differential diagnosis of nodular lesions or sinus tracts present in the axillae, groin, perineal, and mammillary fold regions.

Nail changes due to docetaxel--a neglected side effect and nuisance for the patient.

GOALS OF WORK: The objective of this study is to estimate the frequency and severity of nail changes due to treatment with the cytotoxic drug docetaxel and, secondly, to estimate how the nail changes effects the patients cosmetically and functionally in their daily activities. Finally, we want to clarify whether fungal infection could contribute in causing the nail changes. MATERIALS AND METHODS: Fifty-five patients with metastatic breast cancer in treatment with the cytotoxic drug docetaxel participated in the study. They filled out two questionnaires about their experience with possible nail changes. The frequency of fungal infection was examined. At each of the two visits, information about the number of treatment cycles, dose of docetaxel the patient received, frequency of lymph oedema, previous treatment with chemotherapy and the reason of discontinuance of treatment, if relevant, were registered. Finally, photos were taken to document the nail changes in hands and feet. MAIN RESULTS: Fifty-eight percent had some degree of nail changes and an increase to 88.5% was seen after three additional cycles. A large proportion of the patients experienced the nail changes as a cosmetic nuisance, and more than 32% had functional problems. CONCLUSION: Nail changes occur more frequently than previous studies have shown. Furthermore, our study indicates that the nail changes are affecting a large proportion of the patients, both cosmetically and functionally, which may lead to a decrease in their quality of life. No significant association was found according to the possible relation between nail changes and fungal infection.

Standardised method of surgical treatment of chronic leg ulcers.

Healing and recurrence rates were compared in leg ulcers of different aetiology in 385 patients with 406 chronic leg ulcers. Standard treatment was excision of the ulcer followed by meshed split-skin grafting and correction of superficial venous insufficiency in the area. The median age of the patients was 75 years (range 16-95). After one year 345 patients with 357 leg ulcers were alive. Overall healing rate was 64% (227 in 357 legs) after one year. The best results were achieved in traumatic ulcers (31 in 36 ulcers) and worst for the arterial ulcers (4 in 20 ulcers). Recurrence rate in venous and venous/ischaemic ulcers was 14% (33 in 235 legs) and 8% (n=3) in the traumatic ulcers. Vasculitic ulcers tend to recur 59% (n=10), but the graft does relieve pain.
