RESUMEN
BACKGROUND: Tefillin are a religious article worn by Jewish men during daily prayer. Tefillin dermatitis secondary to potassium dichromate sensitivity is recognised, but data remain sparse. OBJECTIVE: To investigate the prevalence and clinical characteristics of tefillin dermatitis. METHODS: Patients who underwent patch testing with the European baseline series in a tertiary dermatology clinic in 2009-2023 and were diagnosed with tefillin dermatitis were identified by file review and their clinical data recorded. RESULTS: Of 1679 consecutive male patients tested, 25 (1.49%) were diagnosed with tefillin dermatitis, accounting for 15.34% of all potassium-dichromate-positive patients (163/1679). Mean pre-symptomatic duration of tefillin use was 38 ± 16.9 years, and mean follow-up time, 3.1 ± 2.9 years. Patients presented with an eczematous rash on body areas in direct contact with the leather box or straps of the tefillin. An id reaction was noted in 32%, and sensitivity to other leather accessories, in 44%. Fourteen patients (56%) switched to chromate-free tefillin: symptoms resolved completely in 11 (79%) and partially in 2. LIMITATIONS: Retrospective cohort design. CONCLUSION: This is the largest study to date of tefillin dermatitis caused by sensitivity to potassium dichromate used in leather production. Prognosis after switching to chromate-free tefillin was good-to-excellent. Tefillin dermatitis may be more prevalent than previously thought.

BACKGROUND: Pincer nail deformity (PND) is a common toenail disorder characterized by transverse over-curvature of the nail plate. It can cause severe pain, chronic inflammation, and recurrent infections. Both conservative and surgical treatment options carry different disadvantages of limited efficacy, high recurrence rate, and poor cosmetic outcome. The study aimed to evaluate the safety and effectiveness of carbon dioxide (CO2) laser matricectomy for the treatment of PND. METHODS: The database of the laser unit of a tertiary medical center was retrospectively searched for all patients who were diagnosed with PND in 2016-2022 and treated with lateral and/or medial matricectomy using CO2 laser. Clinical and follow-up data were collected from the medical files. Results: The cohort included 19 patients (5 male, 14 female) who underwent 25 partial matricectomies during the study period (some patients had more than one diseased nail). All procedures were successful, with no intraoperative or postoperative complications. There was one documented recurrence at 7 months after treatment. CONCLUSION: Partial CO2 laser matricectomy is safe and effective for the treatment of PND. J Drugs Dermatol. 2023;22(11):1099-1102 doi:10.36849/JDD.7574.

Hair removal with lasers and intense pulsed light (IPL) is considered safe. However, data on the efficacy and safety of these procedures specifically in the pediatric population remain sparse. To determine the efficacy and safety of lasers and IPL for hair reduction in children and adolescents, a systematic review was conducted of original studies evaluating hair removal with lasers or IPL in patients aged less than 18 years. Primary outcome measures were efficacy and safety of treatment. The literature review yielded 2 retrospective cohort studies and 11 case reports/case series including a total of 71 patients aged 9 months to 17 years. Diagnoses ranged from localized lumbosacral to generalized hypertrichosis. Six treatment modalities were evaluated: alexandrite, Nd:YAG, Q-switched Nd:YAG, ruby, and diode lasers and IPL. Only one of the cohort studies (n = 28), using the ruby laser, provided efficacy data. The results showed a 63% hair loss in 89% of patients after completion of treatment, although partial regrowth was evident during 6 to 32 weeks of follow-up. Most of the case reports and case series (10/11) reported significant hair reduction following laser and IPL treatments. None of the patients experienced scarring or dyspigmentation. Some kind of pain management was necessary in 65% of patients; 25% required general anesthesia. On the basis of the limited available data which consisted primary of case reports and case series, lasers and IPL might be effective for pediatric hair reduction. Recurrence following treatment may be higher in children than adults, and pain control may be a limiting factor.

OBJECTIVE: In patients with acute hepatic porphyria (AHP), prolonged fasting is a known trigger of AHP attacks. Despite this, some Jewish AHP patients-mainly hereditary coproporphyria (HCP) and variegate porphyria (VP) patients-fast for 25 consecutive hours during the traditional Jewish holy day known as Yom Kippur. In this study, we evaluated the effect of the fast on these patients. METHODS: A retrospective study and survey of AHP patients in Israel was carried out. Patients were asked whether they have fasted and whether any symptoms were induced by this fast. Patients' medical records were reviewed for an emergency department (ED) visit following Yom Kippur between 2007 and 2019. Only 3 acute intermittent porphyria (AIP) patients reported fasting; they were excluded from analysis. RESULTS: A total of 21 HCP patients and 40 VP patients completed the survey; 30 quiescent patients reported they fast, while 31 did not fast. The majority of fasting patients (96.67%) reported no symptoms following a fast. We found no statistically significant association between ED visits 1 week (0.26% in both fasting and non-fasting patients) or 1 month (2.1% visits in non-fasting versus 0.78% in fasting patients) following Yom Kippur. Of the symptomatic ED visits following a fast, none were defined as severe attacks. CONCLUSION: A 25-hour fast in stable HCP and VP patients did not increase the risk of an acute attack and can probably be regarded as safe.
RESUMEN
Actinic keratoses are common cutaneous lesions with a potential to progress to invasive squamous cell carcinoma. Therefore, treatment is crucial. The Tixel® is a noninvasive thermomechanical device designed to transfer heat to the upper dermis in a controlled manner according to a predetermined setting. This study aimed to evaluate the safety and efficacy of a thermomechanical fractional skin resurfacing technology for the treatment of facial and scalp actinic keratoses. A prospective, open-label, before-after study was conducted in a tertiary medical centre from May 2020 to April 2021. Patients presenting with facial/scalp actinic keratoses of mild-to-moderate thickness underwent 2 or 3 Tixel treatments (depending on clinical improvement), 3-4 weeks apart. The reduction in lesion count and overall improvement in appearance were assessed by clinical examination and digital photography. Findings were compared between baseline and follow-up at 3 months after the last treatment session. Patient satisfaction was evaluated by questionnaire, and adverse effects were documented. A total of 20 patients participated in the study. All completed 2-3 treatments and follow-up visits. Assessment of digital photographs was performed by 2 assessors blinded to the timepoint at which each photo was taken (before or after treatment). The average number of lesions at baseline was 9.8 (± 4.8) and the mean reduction in lesion count was 7.9 (± 4.4) (80.6%). Complete clearance was observed in 31.6% of patients. No adverse effects were noted during treatment and follow-up. Most patients reported being "very satisfied" or "satisfied" with the treatment results (85%) and experience (95%). Treating facial and scalp actinic keratoses with the Tixel device was found to be effective and safe.

BACKGROUND: There is a paucity of data regarding demodicidosis-associated facial hyperpigmentation. OBJECTIVE: To delineate the clinical, dermoscopic, and histopathologic features of demodicidosis-associated facial hyperpigmentation. METHODS: Clinical and diagnostic data were collected from the medical files of patients who were referred to our outpatient dermatology clinic in 2006-2019 for evaluation of facial hyperpigmentation and were diagnosed with demodicidosis. RESULTS: The cohort included 19 patients (13 male) aged 42-76 years, all with Fitzpatrick skin type 3-4. All presented with mostly asymptomatic dusky, brown-gray, facial pigmentation, localized or diffuse with background erythema in 36.8% of cases, and skin roughness in 26.3%. Dermoscopy yielded characteristic findings of white gelatinous or opaque protrusions from hair follicles or infiltration of follicular openings with an amorphic material. A specific finding was perifollicular and reticulated pigmentation of the affected areas. Findings were confirmed on microscopic (n = 7) and histopathologic (n = 5) studies. Anti-demodectic treatment led to complete (73.6%) or partial (23.4%) resolution of pigmentation within 2 years. CONCLUSION: We describe unique clinicopathological and dermoscopic findings associated with an under-recognized type of facial hyperpigmentation caused by demodex for which we propose the term "pigmented demodicidosis." Demodicidosis should be added to the list of causes of facial hyperpigmentation.

The sequential application of fractional ablative/10,600 nm/CO2 followed by 1570 nm non-ablative laser treatment might produce better results than applying either laser treatment alone. However, histological data regarding the safety of this combination is lacking. This study aimed to assess and compare clinical effects, histological tissue damage, and wound healing after monochromatic and sequential fractional laser treatments. In this prospective porcine model study, three adult female pigs were each irradiated using three different wavelengths: (a) monochromatic fractional ablative CO2 laser; (b) monochromatic fractional non-ablative 1570 nm laser; (c) sequential fractional 10,600 nm/CO2 followed by 1570 nm laser treatment. There were six power levels in the monochromatic 1570 nm laser, five in the 10,600 nm/CO2, and five in the sequential treatment. The immediate skin reaction (ISR), crusting and adverse effects, was evaluated across different time points throughout the healing process. Wound biopsies were taken at immediately after (0) and at 3, 7, and 14 days after irradiation. Depth and width of craters, and width of coagulation zone were measured and compared. Similar ISR and crusting score values were obtained following the monochromatic and sequential irradiation in a similar dose-response manner. During 14 days of follow-up, the skin looked intact and non-infected with no signs of necrosis. The mean depth and width of craters were comparable only at the maximal energy level (240 mJ) of CO2 laser, with the coagulation size greater after the sequential treatment. In histology, a similar wound healing was evident. On day 3, crusts were observed above all lesions as was epithelial regeneration. The sequential irradiation with 10,600 nm/CO2 and 1570 nm lasers did not pose any additional risk compared to the risk of each laser alone.

BACKGROUND: Paradoxical hypertrichosis (PH) is an uncommon, poorly understood adverse effect associated with laser or intense pulsed light treatment for hair removal. OBJECTIVE: The objective of this study was to conduct a systematic review and meta-analysis to determine PH prevalence and associated risk factors. METHODS: We conducted a systematic review and meta-analysis of studies evaluating hair removal with lasers or intense pulsed light. Primary outcome was PH prevalence. Meta-regression and subgroup analysis were used to investigate associations among treatment modality, patients' characteristics, and PH. RESULTS: Included were 9733 patients in two randomized controlled trials and 20 cohort studies (three prospective and 17 retrospective). Pooled PH prevalence was 3% (95% confidence interval 1-6; I2 = 97%). Paradoxical hypertrichosis was associated with a face or neck anatomic location, and occurred in only 0.08% of non-facial/neck cases. Treatment modality and interval between treatments had no effect on the PH rate. There were insufficient data to determine the association between sex and skin type to PH. In three out of four studies, PH gradually improved with continued therapy. CONCLUSIONS: Based primarily on cohort studies, PH occurs in 3% of patients undergoing hair removal with lasers or intense pulsed light, yet rarely outside the facial/neck areas. Treatment modality does not seem to be a contributing factor. Continuation of treatment in areas with PH may be the most appropriate treatment.

Solar urticaria is a well-recognized photodermatosis, sometimes accompanied by angioedema. However, isolated solar angioedema (ISA) is a rare and unrecognized entity. The purpose of our work was to systematically review the available data on ISA. Therefore, a systematic review of studies evaluating ISA was performed. Additionally, a case of a 21-years-old patient from our photodermatosis service is presented. The search yielded 421 publications, with 3 eligible for review. Together with our case, 5 cases were included overall. All patients were female. Four out of 5 patients first experienced ISA at childhood or early adulthood (age range 6-22 years). UVA photoprovocation was positive in the 3 out of the 4 patients who were tested. Improvement was noted following NB-UVB hardening (2 out of 5 patients) or a short course of oral prednisone (3 out of 5 patients) combined with regular sunscreen application. To conclude, ISA is an extremely rare entity, although it may be underdiagnosed due to lack of awareness. The clinician must consider ISA in the differential diagnosis of angioedema since it can have a detrimental effect on quality of life. Besides sun avoidance, there is no consensus regarding treatment.

The pulsed dye laser (PDL) is the standard treatment for port-wine stains (PWS). Maximal improvement occurs after multiple treatment sessions; however, the optimal treatment interval has yet to be determined. The aim of this study was to review whether there is an association between PDL treatment interval and outcome of PWS. Six databases were searched by three reviewers for publications investigating treatment of PWS with PDL. The 75% improvement rates (75IR) were extracted for quantitative analysis. Meta-regression was used to investigate the association between treatment intervals and 75IR. The systematic review included 1 RCT and 33 cohort studies (7 prospective cohorts and 26 retrospective cohorts), with a total of 3777 patients. The pooled 75IR was 37% (95% CI 29-45%; I2 = 95%). Light Fitzpatrick skin type (p = 0.04), facial anatomic location (p = 0.01), and young age (p = 0.008) were associated with 75IR. In an unadjusted (p = 0.42) and multivariable adjusted (p = 0.98) meta-regression, no association was found between time interval between treatments and 75IR. These results persisted in a sensitivity analysis of studies with a mean patient age of ≤ 1. The majority of included studies were heterogeneous and retrospective. Based on cohort studies of low-to-moderate quality, time intervals between PDL treatments are not associated with PWS outcome.

BACKGROUND: Inherited genetic erythropoietic protoporphyria (EPP) is characterized by a photosensitive rash that emerges during infancy or early childhood. Acquired EPP can erupt at any age, even during adulthood, and is associated with hematological disorders. A third, less-studied type of EPP is also inherited but appears later in life (during adulthood). PURPOSE: To evaluate the characteristics of inherited genetic late-onset (IGLO) EPP. METHODS: A systematic comprehensive search of the literature was conducted using PubMed, Google Scholar, ScienceDirect, and clinicaltrials.gov databases. Studies describing patients with IGLO EPP were included. Additionally, we present an index case of a patient, treated at our clinic in whom inherited genetic EPP was diagnosed at age 21 years. RESULTS: The search yielded 1514 citations. Five publications were eligible for review. Along with our case, 7 patients (4 males) were included in the analysis. Mean age at disease onset was 34.2 years (range 18-69, median 30). Most patients presented with mild pruritus and rash in a photosensitive distribution. Mean level of free erythrocyte protoporphyrin IX (FEP) was 8.6 µmol/L. A mutant ferrochelatase gene (FECH) in trans to a hypomorphic FECH allele was found in 3 of the 4 patients who underwent genetic testing. CONCLUSION: We describe the distinct features of IGLO EPP. This work emphasizes that a diagnosis of inherited genetic EPP should not be ruled out in adults with new-onset photosensitive manifestations.

Hereditary coproporphyria (HCP) and variegate porphyria (VP) are referred to as neurocutaneous porphyrias (NCP). Data concerning their systemic presentation are limited and no direct attempt of comparison of the two has ever been made. Our aim was to describe the type and frequency of systemic manifestations of NCPs in Israeli patients. A cross-sectional survey was conducted. The study population included all patients with NCP diagnosed at the Israeli National Service for Biochemical Diagnoses of Porphyrias (INSP) between 1988 and 2019. Of the 83 patients with NCP who were alive in 2019, 61 (73%) completed the survey, 40 with VP and 21 with HCP. Systemic symptoms were reported by 63% of the VP group and 62% of the HCP group (p = .96); corresponding rates of cutaneous symptoms were 58% and 5% (p < .001). We found no association between the occurrence of systemic and cutaneous symptoms. Among patients with systemic involvement, abdominal pain was the predominant systemic symptom, found in 64% of the VP group and 69% of the HCP group; Analysis of symptom frequency showed that in 68% of the VP group, systemic symptoms (either abdominal, musculoskeletal or neuropsychiatric) occurred on a daily/weekly basis, whereas the HCP group experienced less than one symptom per week (p < .001). This nationwide study depicts a significantly heavier disease burden in VP patients compared to HCP owing to its more frequent neurovisceral and cutaneous manifestations.
RESUMEN
INTRODUCTION: In a randomized prospective trial, adjuvant rituximab was more efficacious than corticosteroids alone in the treatment of pemphigus; however, real-life data are limited. Rituximab treatment for pemphigus has only recently been introduced to the Israeli health basket. Previously, patients received rituximab if they paid out of pocket or through private insurance, separating patients into 2 treatment groups, mostly based on economic capability. METHODS: A retrospective cohort study of the 12-month clinical response of pemphigus vulgaris/foliaceus patients. We compared patients after a single cycle (1,000 mg on days 0 and 15 or weekly 375 mg/m2 for 4 weeks) of adjuvant rituximab with systemic corticosteroids ± steroid-sparing agents, to patients who were prescribed rituximab, could not obtain it, and received systemic corticosteroids ± steroid-sparing agents. RESULTS: Forty-five patients were included (adjuvant rituximab, n = 29; immunosuppression alone, n = 16). At baseline, rituximab patients had a higher mean pemphigus disease area index (PDAI) (p = 0.07) and higher mean daily dosages of prednisone (1.51 vs. 1.16 mg/kg, p = 0.39). All patients but 1 in the rituximab group continued systemic steroids, and 31% in the rituximab group versus 50% in the immunosuppression-alone group received systemic adjuvants. At 12 months, partial or complete remission rates (on or off maximum 40 mg/day prednisone equivalent) were nonsignificantly higher in the rituximab group (62 vs. 50%, p = 0.53); however, patients on rituximab showed faster remissions (3.4 ± 1.9 vs. 5.9 ± 3.6 months; p = 0.03) with a trend for a greater PDAI reduction (p = 0.051). Adverse events were comparable. CONCLUSIONS: In this real-life study, a single cycle of rituximab achieved more remissions and sooner compared to conventional immunosuppression, but the differences were not significant, probably due to a small sample size and severe baseline disease in the rituximab group. Future real-life studies on larger groups are needed.

BACKGROUND: Surgery is the mainstay of treatment for non-melanoma skin cancer. Lasers are an additional option. OBJECTIVE: The objective of this study was to review the literature on the efficacy and safety of lasers for the treatment of non-melanoma skin cancer. METHODS: A systematic review and meta-analysis of laser treatment for non-melanoma skin cancer was performed. The primary outcome was recurrence rate (RR). RESULTS: The review included 32 studies (six randomized controlled trials and 26 cohort studies): 27 evaluated basal cell carcinomas (BCCs), three squamous cell carcinomas, and two both, for a total of 4755 BCCs and 214 squamous cell carcinoas. Most BCCs were low risk. The Nd:YAG laser (seven studies, 3286 BCCs) had a 3.1% RR (95% confidence interval [CI] 1.4-6.4%) during a mean follow-up of 7.9 years, with a low rate (< 20%) of scarring and dyspigmentation. The CO2 laser (ten studies, 904 BCCs) had a 9.4% RR (95% CI 4.1-20) during a mean follow-up of 2.1 years, with a low rate of side effects. The pulsed dye laser (eight studies, 206 BCCs) had a 38% RR (95% CI 24-55). In two studies, the Nd:YAG laser demonstrated a RR of 10% (95% CI 2-31) for Bowen's disease, and in three studies, the CO2 laser demonstrated a RR of 22% (95% CI 5-61) for squamous cell carcinoma. CONCLUSIONS: Based on cohort studies, the Nd:YAG laser is a safe and efficacious modality for the treatment of low-risk BCC. Based on settings applied in prior studies in the literature, the CO2 laser is less efficacious than the Nd:YAG laser, thus it cannot be recommended for BCC treatment. Insufficient data preclude conclusions regarding laser treatment for squamous cell carcinoma. REGISTRATION: PROSPERO registration number CRD42019129717.

BACKGROUND: There are three major types of genetic cutaneous porphyrias (GCP): erythropoietic protoporphyria (EPP), variegate porphyria (VP), and hereditary coproporphyria (HCP). Scarce data are available regarding their impact on patients' quality of life in the Mediterranean region. PURPOSE: To describe the cutaneous features of GCP in Israel. METHODS: An established nationwide cohort of patients with GCP diagnosed during 1988-2019 was surveyed by telephone for cutaneous features of GCP. Impact on quality of life was assessed using the Dermatology Life Quality Index. RESULTS: Of the 95 patients with GCP, 71 (75%) completed the survey (21 HCP; 40 VP; 10 EPP). All EPP patients reported cutaneous symptoms compared with 58% of VP and 5% of HCP (P < .001). Mean age at symptom onset was 7 ± 6 years in EPP and 25 ± 15 years in VP (P < .001). Photosensitivity was the most common symptom in EPP (90%). In VP photosensitivity (52%), blistering (52%) and scarring (74%) were all common symptoms. In both VP and EPP, the dorsal hands/forearms were the most affected regions (≥96%), and in ≥ 78%, symptoms occurred on an almost daily basis. All EPP patients changed their lifestyle due to cutaneous symptoms vs 57% in VP. Major effect on quality of life was observed among EPP patients compared with a moderate effect in VP. No treatment was effective in EPP, while phototherapy and moisturizers were effective in 5 of 7 (71%) VP patients. CONCLUSION: This study sheds light on the cutaneous features of the GCP, which have a substantial effect on patients' quality of life.

BACKGROUND: The incidence of epidermal growth factor receptor inhibitor (EGFRI)-induced papulopustular rash is 60-85%. OBJECTIVE: To investigate prophylactic topical treatment for EGFRI-induced rash. METHODS: A single-center, randomized, double-blind, placebo-controlled trial. Adult cancer patients initiating treatment with EGFRIs were randomized to receive facial topical treatment with chloramphenicol 3% + prednisolone 0.5% (CHL-PRED) ointment, chloramphenicol 3% (CHL) ointment, or aqua cream (AQUA). The primary end points were the incidence of ≥grade 3 rash using the Common Terminology Criteria for Adverse Events (CTCAE), on days 14 and 30. A subanalysis was conducted for incidence of a protocol-specified significant rash, defined as ≥10 facial papulopustular lesions. RESULTS: The per-protocol analysis on day 14 included 69 patients, who received CHL-PRED (21), CHL (23), or AQUA (25). The incidence of CTCAE ≥grade 3 rash was not statistically significant between arms; however, the incidence of the protocol-specified significant rash was: CHL-PRED 14%, CHL 39%, and AQUA 48% (p = 0.03, CHL-PRED vs. AQUA). At 30 days, the CTCAE ≥grade 3 incidence was similar, but the incidences of protocol-specified significant rash were 6%, 16%, and 43% (p = 0.03, CHL-PRED vs. AQUA). No significant differences were found between CHL and CHL-PRED and between CHL and AQUA. CONCLUSIONS: Prophylactic topical CHL-PRED was efficacious when compared to AQUA, in the treatment of EGFRI-induced facial papulopustular rash.

BACKGROUND: Genital warts, caused by the human papillomavirus, are a common sexually transmitted disease. The warts can regress spontaneously or exhibit a persistent clinical course. Various therapeutic modalities are available, yet none is curative, and there may be recurrences. Retinoids are considered the mainstay of therapy in many dermatologic diseases. Data on their use for genital warts are limited. OBJECTIVE: To systematically review the published evidence on the efficacy and safety of retinoids for the treatment of genital warts. METHODS: A systematic review and meta-analysis of all publications evaluating topical or systemic retinoids for the treatment of genital warts was performed. The primary outcome was complete response (CR); the secondary outcomes were recurrence rate and adverse events. RESULTS: Six publications were evaluated, three randomized controlled trials and three prospective cohort studies, including a total of 141 patients with genital warts treated exclusively with retinoids (90% with isotretinoin). CR rates were 100% for systemic etretinate (3 out of 3 patients, 95% CI 28-81%) and 56% for isotretinoin (95% CI 28-81%; I2 = 84%). Topical etretinate did not induce CR. The most common side effect of topical agents was irritant contact dermatitis (36%) and that of systemic agents mucocutaneous disorders (80%). The relapse rate was 12% for oral isotretinoin and was unavailable for the other modalities. CONCLUSIONS: Current data suggest that unlike topical retinoids, systemic retinoids are an effective and safe treatment for genital warts. Further studies are required to determine their specific role and the most effective regimen for each derivative.

Cutaneous viral warts (CVW), caused by human papillomavirus, often have a self-limited course. However, some patients experience a recalcitrant disease despite treatment. Retinoids are considered the mainstay of therapy in many dermatologic diseases. Data on their use for viral warts are limited. To systematically review the published evidence on the efficacy and safety of retinoids for the treatment of CVW. A systematic review and meta-analysis of topical or systemic retinoid treatment for CVW was performed in accordance with the PRISMA statement. The primary outcome was clinical response; secondary outcomes were recurrence rate and adverse events. Fourteen publications including 399 patients treated exclusively with retinoids (65% topical, 35% systemic) were evaluated. The complete response rate was 64% (95% CI, 46-78%; I2 =80%) for topical treatment and 61% (95% CI, 44-76%; I2 =69%) for systemic treatment. The most common side effects were irritant contact dermatitis and cheilitis, respectively. Relapse rates were 6% and 17%, respectively. The reviewed studies were considerably heterogenous and most lacked a control group. Both topical and systemic retinoids are effective and safe as monotherapy for CVW. Further studies are required to determine their exact role in this setting.

High levels of efficacy were demonstrated in randomized controlled trials assessing the efficacy of guselkumab; however, real-life data are lacking. In this retrospective cohort study, we assessed the efficacy and safety of guselkumab in a cohort of psoriasis patients heavily pretreated with biologic agents. Primary efficacy endpoint was the percentage of patients achieving ≥psoriasis area and severity index (PASI) 90 response at week 24. The cohort included 33 patients of mean age 60 ± 13 years. Guselkumab was initiated after a mean of 4.0 ± 1.0 prior biologics failed over a mean period of 7. 4 ± 3.8 years. The mean duration of guselkumab treatment was 9.5 ± 3.7 months; 29 patients completed at least 24 weeks of treatment. At week 24, 22 patients (76%) achieved response of PASI 75 or higher, 18 (62%) achieved PASI 90 or higher, five (17%) PASI 100, and seven (24%) ≤PASI 50. No adverse effects were observed. This study confirms the efficacy and safety of guselkumab in real-world clinical practice, although for a lesser degree compared with clinical trials.

INTRODUCTION: Surgery is commonly regarded as the mainstay of treatment of extramammary Paget disease (EMPD); however, nonsurgical approaches have gained popularity in recent years. OBJECTIVES: To review the published evidence for the efficacy and safety of nonsurgical modes of therapy for EMPD. METHODS: A systematic review and meta-analysis of nonsurgical EMPD treatments was performed. The primary outcome was complete response (CR); secondary outcomes were clinical regression by ≥50%, adverse events, and recurrence rate. RESULTS: The systematic review included 43 observational studies (341 patients; 7 prospective cohort studies, 19 retrospective cohort studies, and 17 cases series) evaluating 5 treatment modalities. Imiquimod (13 studies, 110 patients) administered at variable doses ranging from daily to twice weekly for 2-56 weeks demonstrated CR of 54% (95% CI, 40-67%; I2 = 37%) and had a satisfactory safety profile. In 14 heterogeneous studies (122 patients) evaluating photodynamic therapy (PDT), only 36% (95% CI, 22-53%; I2 = 52%) of patients achieved CR. Radiotherapy (12 studies, 67 patients) showed CR of 97%, but was associated with local and systemic side effects. Ablative lasers and topical fluorouracil and calcipotriene lacked adequate evidence of efficacy. CONCLUSIONS: Imiquimod and radiotherapy are the most appropriate nonsurgical modalities for EMPD treatment given their good efficacy and safety profile. PDT has limited efficacy but may be appropriate in selected clinical settings.
