Metformin in Hidradenitis Suppurativa: Is It Worth Pursuing Further?

Hidradenitis suppurativa (HS) often coexists with obesity, metabolic syndrome, diabetes mellitus, or impaired glucose tolerance and insulin resistance and polycystic ovarian syndrome. Metformin is a medication used for the treatment of diabetes, acting in multiple ways. There is evidence that it decreases inflammatory cytokines, some of which are implicated in the pathogenesis of HS (TNF-α, IL-17). We performed a systematic review of data regarding the efficacy and safety of metformin for the treatment of HS. Four electronic databases (MEDLINE, ScienceDirect, Cochrane Library, and ClinicalTrials.gov), as well as the abstracts compendia of major dermatologic congresses, were searched. A total of 133 patients received metformin for HS across 6 studies, 117 of whom received it as monotherapy. The great majority of participants were female, in their thirties and overweight or obese, with one study including only children. The efficacy tools employed varied widely. Four studies (106 patients) documented improvement, 1 documented treatment failure, and 1 had mixed results. Only mild and transient side effects were noted. Metformin has been tried in few HS patients with acceptable efficacy in a fair number of them. As it is generally well tolerated and reasonably priced, carefully designed clinical trials comparing it with placebo are worth performing.

Eight Month-Old-Infant Impaled by Toothbrush Through the Hard Palate.

Impalement of children with foreign bodies is not uncommon. A variety of foreign bodies and mechanisms of injuries have been described. Infant tissues are more vulnerable to injuries and often penetrating traumas are very dangerous. An 8-month-old infant was referred to our department with a major impalement injury of his hard palate by a toothbrush. The integrity of the orbit was in question due to the high proximity of the foreign body to the lamina papyracea. A well-structured algorithm was followed to secure the best interests of the child. Our approach minimizes the risk of complications by taking into account every single parameter. After the removal of the foreign body, a careful reconstruction with meticulous nasendoscopy was held to restore the hard palate integrity and to check the orbit inner wall. According to the literature, toothbrushes seem to be the most common medium of impalement trauma. Parents should be educated that their offspring are at great risk when holding or sucking objects while playing.

Quality-of-Life Endpoints in Women of Childbearing Age with Hidradenitis Suppurativa: A Tertiary-Care-Centre-Based Study.

Background: Hidradenitis suppurativa (HS) principally affects women of childbearing age, who face gender-specific challenges and have lower life-quality than men. HS also seems to impact desire for procreation. Objective: To investigate various quality-of-life endpoints in women of childbearing age with HS. Study design: A cross-sectional questionnaire-based study was performed at a university dermatology department. Eighteen yes/no and one open-ended questions explored impact of HS on social life, sexual life, family planning, working life and healthcare-backed support. A sensitivity analysis was performed for women under 25, who are significantly less likely to be married/in a permanent relationship in Greece, as this could act as a confounding factor regarding family planning. Results: Ninety-six women were included. Most women (80.8%) carry a stigma because of HS, which also affects their choice of clothes and social relationships. Sexual impairment affects 73.1% of women. One third of women wants less or no children because of HS, 67.7% worry about its impact on pregnancy, birth, and the postpartum, and 84.6% worry about the impact of HS treatment on fertility and their babies' health. Almost 43% fear losing their job because of HS, 34.4% are discriminated against at work and 33.3% state HS has hindered their career. Most women are not adequately informed about their disease or available support groups/material and 41.7% have not received good enough care through pregnancy/postpartum. Conclusions: Life-quality endpoints should be meticulously screened in women. Multidisciplinary-led treatment should be offered during pregnancy and the postpartum.

Apremilast in Psoriasis Patients With Serious Comorbidities: a Case Series and Systematic Review of Literature.

Introduction: Patients with serious comorbidities are traditionally excluded from clinical trials. Apremilast is not contraindicated in active infections, malignancy and serious hepatic or renal impairment, but real-life data is needed to support this recommendation. Objectives: The aim of this paper is to present our personal as well as literature-sourced real-world evidenced on apremilast use in psoriasis patients with serious baseline comorbidities. Methods: A case-series and systematic literature review were performed. The psoriasis archives of a tertiary-care hospital, four electronic databases (MEDLINE, ScienceDirect, Cochrane Library, Google scholar) and other sources were searched (January 2014 - July 2021). Identified records were considered eligible, if they reported on the use of apremilast monotherapy in psoriasis patients with chronic infections, history of malignancy, serious liver, renal, psychiatric, or other disease(s). Results: At least 841 psoriasis patients with serious baseline diseases received apremilast. Only 3 cases of cancer progression and no infection reactivations or worsening of other diseases were documented. No increased frequency/severity of adverse events or reduced drug efficacy were noted. Main limitations of this study are the exclusion of a few reports due to inappropriately documented data and the fact that at least some patients might have been counted more than once. Conclusions: Apremilast is a safe and adequately efficacious option for psoriasis that cannot be treated/is challenging to treat with classic systemic agents and/or biologics.

New and Upcoming Topical Treatments for Atopic Dermatitis: A Review of the Literature.

Atopic dermatitis (AD) is a chronic inflammatory dermatosis with periods of exacerbation and remissions. AD is characterized by intense, persistent pruritus and heterogeneity in clinical symptomatology and severity. Therapeutic goals include the amelioration of cutaneous eruptions, diminishing relapses and eventually the disease burden. To date, topical corticosteroids (TCS) and calcineurin inhibitors (TCI) have yet been deemed the mainstay of topical treatments in AD management. Nevertheless, despite their indisputable efficiency, TCS and TCI are not indicated for continuous long-term use given their safety profile. While research in AD has concentrated predominantly on systemic therapies, more than 30 novel topical compounds are under development. The existing data appear encouraging, with some regimens that are already FDA-approved (ruxolitinib was the most recent in September 2021) and several pharmaceutical pipeline products for mild-to-moderate AD that are in an advanced stage of development, such as tapinarof, difamilast and roflumilast. Larger, long-term studies are still required to evaluate the efficacy and safety of these novel compounds in the long run and weigh their advantages over present treatments. In this review, we aim to provide an overview of the latest knowledge about AD topical treatments, echoing upcoming research trends.

Hidradenitis-suppurativa-bedingte Kosten, ein Plädoyer für Aufmerksamkeit: eine systematische Literaturübersicht.

Die Daten zu Hidradenitis suppurativa (HS)-bedingten Kosten sind begrenzt und inhomogen. Sie sind jedoch erheblich. Wir führten eine systematische Sichtung der Literaturberichte durch, in denen finanzielle Daten über jeden Gesundheitsbereich oder andere Ausgaben dokumentiert wurden, die durch HS und/oder HS-bedingte Auswirkungen auf Beschäftigung, Einkommen und persönliches wirtschaftliche Entwicklung entstanden sind (indirekte Kosten). Dafür wurden drei elektronische Datenbanken durchsucht (MEDLINE, ScienceDirect und die Cochrane Library -letzte Suche: 14. September 2021). Alle Kosten wurden inflationsbereinigt (2022) und in US-Dollar umgerechnet. Es wurden 23 Artikel eingeschlossen (18 Krankheitskostenstudien, 4 Beobachtungsstudien und 1 Fallserie), in denen ökonomische Daten von 77.287 HS-Patienten erfasst wurden. Die durch HS entstandenen durchschnittlichen jährlichen Kosten pro Patient reichten von 258 $ bis 8.078 $. Diese Zahl erhöhte sich bei chirurgischen Eingriffen, Krankheitsprogression, Antibiotika-Versagen und bestimmten Begleitkrankheiten. Der kostspieligste Faktor war die stationäre Versorgung, gefolgt von ambulanter und Notfallversorgung. Signifikante Unterschiede wurden zwischen den USA und den übrigen untersuchten Ländern beobachtet. Im Vergleich zu Psoriasis-Patienten waren Krankenhausaufenthalte bei HS wahrscheinlicher, länger und kostspieliger, während die weniger kostspielige ambulante Versorgung bei HS-Patienten verringert war. Das Vermeiden der Krankheitsprogression durch frühzeitige Diagnose und Optimierung der ambulanten dermatologischen Versorgung könnte HS-bedinge Ausgaben reduzieren.

Hidradenitis suppurativa-related expenditure, a call for awareness: systematic review of literature.

Data regarding hidradenitis suppurativa (HS)-related expenditure is limited and non-homogeneous, but HS does incur significant expenses. We performed a systematic review of literature reports documenting financial data regarding any healthcare domain or other expenditure incurred by HS and/or HS impact on work, income and personal economic growth (indirect costs). Three electronic databases were searched (MEDLINE, ScienceDirect, and the Cochrane Library - last search date: September 14th , 2021). All costs were adjusted for inflation (2022) and converted into US dollars. Twenty-three papers were included (18 cost-of-illness studies, 4 observational studies and 1 case series), drawing economic data from 77,287 HS patients. The total mean cost incurred by HS per patient per year ranged from $ 258 to $ 8,078. This number increased in case of surgical intervention, disease progression, antibiotic failure and certain comorbid diseases. The costliest healthcare sector was inpatient care, followed by outpatient and emergency care. Significant differences were observed between the USA and the rest of studied countries. Hospitalization was likelier, lengthier, and costlier for HS compared to psoriasis patients, whereas the less costly outpatient care appeared to be reduced among HS patients. Preventing disease progression by optimizing early diagnosis and dermatology outpatient care could decrease HS-related expenditure.

Adalimumab Effect on Pain in Hidradenitis Suppurativa Patients: Systematic Review and Meta-Analysis.

Introduction: Pain is experienced by most patients with hidradenitis suppurativa (HS) and has a severe impact on their quality of life. Its management still presents a challenge. Adalimumab, a TNF-a antagonist, has shown promising results in HS-related pain reduction. Objectives: To aggregate and synthesize all existing evidence regarding the effect of adalimumab on HS-associated pain. Methods: We identified original controlled and uncontrolled studies with participants receiving adalimumab, which included change in pain score post-treatment compared to baseline as an end-point. We searched MEDLINE, ScienceDirect, the Cochrane Library, ClinicalTrials.gov and International Clinical Trials Registry Platform. The primary endpoint of our study was the mean change (continuous variable) of pain scores at week 12 compared to baseline. Results: We performed a meta-analysis of 4 randomized controlled trials (282 patients in the intervention group and 266 patients in the control group). Adalimumab brought about a 0.418 reduction in mean pain score at its worst with 95%CI [-0.588, -0.248] and P = 0.000 at 12 weeks after treatment commencement. Four more studies were included in a qualitative synthesis, 2 of which reported statistically significant reduction in pain scores at week 12. Conclusions: Adalimumab could be prescribed more readily in cases of HS associated with significant pain.

Apremilast Survival and Reasons for Discontinuation in Psoriasis: Five-Year Experience From a Greek Tertiary Care Centre.

Introduction: Drug survival is an indirect measure of efficacy and safety and its post-marketing assessment using real-life data is invaluable. Objectives: To investigate the survival of apremilast in a cohort of psoriasis patients treated with apremilast in a Greek hospital. Methods: A retrospective cross-sectional study examined adult psoriasis patients receiving apremilast (March 2016 to January 2021). Primary endpoint was the cumulative survival probability at 52 weeks. Kaplan-Meier analysis was used to calculate survival probability. Cox regression analysis was performed to investigate potential risk factors for apremilast discontinuation. Results: One hundred and two patients (29.4% females) with a mean age of 55.9 years (standard deviation 15.21) were included. Sixty-five patients (63.7%) had discontinued treatment by lock date: 19 (18.6%) due to lack of efficacy, 24 (23.5%) due to loss of efficacy, 15 (14.7%) due to adverse reactions, and 7 (6.9%) due to other reasons. Cumulative survival probability at 52 weeks was 52.1%. Median survival time for all reasons for discontinuation was 58 weeks (95% Confidence Interval 40.02, 75.98). Conclusions: Approximately half of patients remained on apremilast after 1 year of treatment. Secondary drug failure was the most common reason for discontinuation.

Treatment strategies for hidradenitis suppurativa: real-life data from a tertiary Greek hospital.

Hidradenitis suppurativa (HS) is a difficult-to-treat chronic relapsing skin disease, which greatly impacts the quality of life. To bring forward real-life challenges in the decision-making process regarding HS treatment. A retrospective observational study was performed with treatment-related data derived from the HS archive of tertiary hospital-based First Department of Dermatology and Venereology of Aristotle University, Greece. Data were available for 121 patients, 63 men (52.7%) and 58 women (47.93%) with a mean age of 38 years. Doxycycline 100 mg twice daily for 1-2 weeks and then once daily for up to a total of 12 weeks was the most popular treatment choice (80 patients, 66.12%), administered for mild-to-moderate disease. Biologics were the second most frequently prescribed treatment, reserved for moderate-to-severe disease (adalimumab: 26 patients, 14.88%, infliximab: 2 patients, 1.65%). All in all, a wide variety of treatment regimens were implemented, with various combinations of topical and systemic agents. Real-life practice reflects the relative paucity of high-quality evidence regarding HS treatment and the absence of a unanimously preferable therapeutic option, leaving both dermatologists and patients defenceless against disease progress and sequelae.

18F-FDG-PET/CT interpretation pitfalls in patients with head and neck cancer.

AIM: The aim of the present study is to raise awareness of ENT Surgeons on the limitations of 18F-FDG PET/CT in head and neck cancer by presenting illustrative cases from our department archives. MATERIALS AND METHODS: A retrospective chart review was conducted for all patients with head and neck cancer treated in our ENT department from 2015 to 2020. Cases with various interpretation pitfalls due to false-positive and false-negative PET/CT results that lead to diagnostic dilemmas and treatment delays either in their pre-therapeutic work-up or in their post-therapeutic monitoring were included. RESULTS: Five cases of various image interpretation pitfalls (3 false negative and 2 false positive cases) were identified and are presented in detail. CONCLUSIONS: Although 18F-FDG PET/CT has gained in popularity and improved head and neck cancer management, clinicians should be aware of its limitations. The combination of 18F-FDG PET/CT with other imaging modalities can reduce the number of interpretation pitfalls but by no means will substitute sound clinical judgement.

Re-Evaluating Limitations in Atopic Dermatitis Meta-Analysis Is Important in Interpreting its Results : Limitations of Atopic Dermatitis meta-analysis.

A recently published systematic review and meta-analysis concludes that topical calcineurin inhibitors (TCIs) used in atopic dermatitis (AD) increase risk of lymphoma. We believe this study has weaknesses that have not been adequately addressed by the authors and its results must therefore be interpreted with caution. According to study results only pimecrolimus used for AD was statistically significantly associated with lymphoma, and not TCIs in general. Unclear participant baseline immunocompetence and short follow-up duration limit the study's ability to detect malignancy risk. AD has been linked to an increased risk of lymphoma; however, cutaneous lymphoma can be misdiagnosed as AD, which makes it possible that the disease itself rather than treatment with TCIs could account for any increased likelihood of lymphoma in these patients. It is important that clinicians not be wrongfully made more reserved and insecure about prescribing TCIs in the future.

Schwannoma of the Zygomatic Branch of the Facial Nerve.

SIGNIFICANCE STATEMENT: Facial nerve schwannoma is extremely uncommon. Despite its rarity, it is considered the most common facial nerve tumor and potentially affects any segment of the nerve. Presenting symptoms vary depending on the location of the neoplasm. Tumors pertaining to the extratemporal course of the nerve mainly appear as an asymptomatic parotid mass. We present a rare case of schwannoma of the zygomatic branch of the right facial nerve that was surgically resected, without facial nerve injury.

Human Papillomavirus Vaccine to End Oropharyngeal Cancer. A Systematic Review and Meta-Analysis.

ABSTRACT: Oropharyngeal cancer (OPC) is currently the most frequent human papillomavirus (HPV)-related malignancy in high-income countries. Oral HPV16 infection is the cause of HPV-related OPC in more than 90% of cases and is primarily (90%) linked to oral sex. This systematic review and meta-analysis aimed at comparing the prevalence of oral vaccine-type HPV infection in individuals vaccinated with HPV vaccines and unvaccinated controls. Three databases (MEDLINE, ScienceDirect, and the Cochrane Library), as well as other sources, were searched by 2 independent reviewers. Controlled studies testing the efficacy or effectiveness of licensed HPV vaccines were included. The primary end point was multiple oral HPV infections in one individual with low-risk and high-risk types. Secondary end point was the number of oral HPV16 infections. Six studies-2 randomized controlled trials and 4 cross-sectional studies-with a total of 15,240 participants were included in a meta-analysis, which showed that vaccinated individuals were 46% (risk ratio, 0.54; 95% confidence interval, 0.32-0.91) less likely to develop oral vaccine-type HPV infection (P = 0.02). A second meta-analysis of 4 studies (1 randomized controlled trial and 3 cross-sectional studies) and 13.285 participants showed 80% (risk ratio, 0.20; 95% confidence interval, 0.09-0.43) less likelihood of oral HPV16 infection (P < 0.0001). This study suggests that HPV vaccines can protect against oral vaccine-type HPV infection including high-risk HPV16 infection, thus reducing the incidence of HPV-related OPC. Vaccination against HPV, especially in males, who are predominantly affected by HPV-related OPC, could result in the prevention of this disease.

Under Development JAK Inhibitors for Dermatologic Diseases.

Molecular targeting therapies represent a new exciting era in dermatology. A promising novel drug class, subject of intense research, is Janus kinase (JAK) inhibitors. Multiple cytokine receptors signal through the Janus kinase and signal transducer and activator of transcription (STAT) pathway. The pathway plays a central role in innate and adaptive immunity, and haematopoiesis. The understanding of the contribution of JAKs to the immunologic processes of inflammatory diseases led to the development of JAK inhibitors, initially for rheumatologic and hematologic diseases. Soon, their efficacy in some dermatologic conditions was also demonstrated, and today their role as therapeutic agents is thoroughly researched, mainly in atopic dermatitis, psoriasis, vitiligo, and alopecia areata. JAK inhibitors can be administered orally or used topically. As they are relatively new treatment modalities in dermatology, many questions concerning their efficacy and safety remain unanswered. Data from ongoing trials are eagerly awaited. Here, we summarize under development JAK inhibitors for dermatologic diseases.

Prevalence of onychomycosis among patients with nail psoriasis who are not receiving immunosuppressive agents: Results of a pilot study.

Nail psoriasis and onychomycosis can often be hard to differentiate clinically and may coexist, complicating each other's course. The aim of this study was to determine the prevalence of onychomycosis among patients with nail psoriasis not being treated with immunosuppressive agents, which constitute an independent risk factor for fungal infections. A cross-sectional study was performed. All adult patients with nail psoriasis who were not receiving antifungal and/or immunosuppressive treatment were recruited at the 2nd University Dermatology Department of Aristotle University of Thessaloniki from 10/2016 till 02/2017. If onychomycosis was clinically suspected, nail samples were collected and direct microscopy with 15% KOH solution and culture were performed. Target-NAPSI and DLQI score were also calculated. Of the 23 patients recruited, 20 were men and 3 were women, with a mean age of 53.43 years (48.25, 58.62), a mean target-NAPSI score of 10.72 (9.62, 11.77) and a mean DLQI score of 10.17 (7.46, 12.89). A total of 34.78% of patients tested positive for onychomycosis. Yeast were isolated in 37.50% of cases, non-dermatophyte filamentous fungi in 37.50% and T. rubrum in 12.50%. The prevalence of onychomycosis among nail psoriasis patients is higher than that among the general population of Greece (15%-20%). Yeast and moulds predominate in infection cases of nail psoriasis patients.
