Introduction: Localized bullous pemphigoid (LBP) is an infrequent bullous pemphigoid (BP) variant restricted to a body region. According to the most compelling evidence, LBP occurs in patients with pre-existent serum antibodies against the basement membrane zone, which occasionally acquire the capacity to induce disease after the influence of different local factors acting as triggers. Methods: We hereby present a multicenter cohort of 7 patients with LBP developed after local triggers: radiotherapy, thermal burns, surgery, rosacea, edema and a paretic leg. In addition, we conducted a review of the literature, and we propose a set of diagnostic criteria for LBP, also based on our case series and the 2022 BP guidelines from the European Academy of Dermatology and Venereology. Results: During follow-up, three of the patients from our series evolved to a generalized BP, with only one requiring hospitalization. Our literature search retrieved 47 articles including a total of 108 patients with LBP, with a 63% with a potential local precipitating factor previous to their diagnosis. LBP mostly affected older females, and a subsequent generalized progression occurred in 16.7% of the cases. The most frequently involved areas were the lower limbs. Radiation therapy and surgery were responsible for the inducement of nearly 2 in 3 cases of LBP. We observed a significantly higher risk of generalization in cases where the trigger led to the developing of LBP earlier (p=0.016). Our statistical analysis did not detect any other prognosis factor for generalization when assessing direct immunofluorescence, histological and serological results, or other patient related factors. Conclusion: LBP should be suspected in patients with recurrent localized bullous eruptions. The presence of a trauma history in the same anatomic area is reported in most cases.

Background: Ablative treatment of anal high-grade squamous intraepithelial lesions (HSIL) reduces the risk of progression to anal squamous cell carcinoma. Objectives: To identify factors that influence the response to treatment of anal HSIL by electrocautery ablation (ECA) in a population of HIV-positive men who have sex with men (MSM). Design: Retrospective study of ECA treatment response in a prospectively followed anal dysplasia cohort. HIV-positive MSM diagnosed with anal HSIL were included. Demographic and HIV data were recorded. Response to treatment was assessed by biopsy after at least 18 months of follow-up. Results: One hundred and twenty-eight HSILs in 91 men were included in this study. The overall response rate at 18 months was 70.3%. The number of electrocautery sessions required (2 ECA sessions vs 1: adjusted odds ratio [aOR] = 0.36 (95%CI 0.13-1.01); >=3 sessions vs 1: aOR = 0.10 (95%CI 0.04-0.29); p < 0.001]) and the history of previous HPV-related anal pathology (previous anal lesions vs no previous lesions AOR = 2.83 (95%CI 1.14-7.02), p = 0.024) were independently associated with response at 18 months. No serious adverse events were reported. Conclusions: Consideration should be given to alternative therapies in patients with unresolved HSIL after 1 ECA treatment. [ABSTRACT FROM AUTHOR]

Purpose: To report on the short-term visual and refractive outcomes of laser-assisted in situ keratomileusis (LASIK) for the correction of myopia carried out with a VisuMax femtosecond laser (for flap creation) and a MEL 90 excimer laser (for ablation) (Carl Zeiss Meditec, Jena, Germany). Methods: A retrospective non-comparative case series study was carried out analysing 382 myopic LASIK procedures (191 patients) treated at a single site (Optegra Eye Hospital, London, UK) by a single surgeon using the VisuMax femtosecond laser for flap creation and a MEL 90 excimer laser (Carl Zeiss Meditec). A triple-A ablation profile was selected at 500 Hz for all treatments and the inbuilt nomogram was selected. Attempted spherical equivalent refraction and cylinder ranged from -0.50 D to -11.00 D and 0.00-5.00 D, respectively. Outcomes were analysed at the last postoperative visit using internationally agreed methods for reporting refractive surgery outcomes. Results: There were no operative complications. Postoperative assessments were typically carried out during the first 3 months after surgery. Visually insignificant postoperative complications, such as dry eye, were noted in 84 eyes (22%). A total of 353 eyes (92%) achieved 6/6 or better unaided distance visual acuity (UDVA) postoperatively compared with 370 eyes (97%) presenting with 6/6 corrected distance visual acuity (CDVA) preoperatively. In all, 359 eyes (94%) had a UDVA postoperatively within one line of preoperative CDVA. No eyes lost two or more lines of CDVA. Postoperative mean spherical equivalent refraction was within +0.50 D in 349 eyes (91%) and within +1.00 D in 376 eyes (98%). Conclusions: LASIK with the VisuMax femtosecond laser and MEL 90 excimer laser using an aspherically optimised ablation profile that also focuses on minimal tissue removal (triple-A ablation profile) at 500 Hz pulse rate is a safe, predictable and efficacious method for the correction of myopia up to -11.00 D and cylinder up to 5.00 D.

Background Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by Chlamydia trachomatis (CT) serovars L1, L2, and L3 and is endemic among men who have sex with men (MSM) in Europe. We evaluated weekly oral azithromycin 1 g for 3 weeks as a treatment for LGV proctitis. Methods This is an open clinical trial with convenience allocation according to treating physician preferences. Adults with clinical proctitis received a single dose of 1 g of intramuscular ceftriaxone and were subsequently allocated to receive (i) doxycycline 100 mg twice daily for 21 days (Doxycycline group) or (ii) azithromycin 1 g orally once weekly for 3 weeks (Azithromycin group). LGV cure (primary endpoint) was defined as resolution of symptoms at week 6 (clinical cure, LGV-CC), with an additional supporting negative rectal polymerase chain reaction (PCR) at week 4 (microbiological cure, LGV-MC), if available. Results One hundred and twenty-five individuals with LGV clinical proctitis were included. All were MSM, and 96% were living with human immunodeficiency virus (HIV). Eighty-two were in the Azithromycin group, and 43 were in the Doxycycline group. LGV cure on a modified intention-to-treat analysis (primary endpoint), occurred in 80 of 82 (98%) in the Azithromycin group versus 41 of 43 (95%) in the Doxycycline group (treatment difference [95% confidence interval {CI}] 2.2% [−3.2, 13.2]). LGV-MC occurred in 70 of 72 (97%) vs 15 of 15 (100%) in the Azithromycin group and Doxycycline group, respectively (treatment difference [95% CI] −2.8% [−9.6; 17.7]). Adverse events were similar in both treatment groups. Conclusions Our findings support extended azithromycin dosing as an alternative treatment option for symptomatic LGV proctitis and provides the rationale for future randomized trials.

Adalimumab is the only approved biological therapy for hidradenitis suppurativa (HS). The last published recommendations support the use of other off-label biologic therapies. We report on a multicentric retrospective review of patients with HS treated with an ustekinumab dosing schedule of intravenous infusion adjusted by weight, followed by a subcutaneous maintenance dose of 90 mg every 8 weeks, as recently approved for Crohn's disease. The minimal follow-up period required for inclusion was 16 weeks. A total of 14 patients from six hospitals were included. In 50% of the treated patients, therapeutic outcomes, measured by means of the Hidradenitis Suppurativa Clinical Response (HiSCR) and decrease of Dermatology Life Quality Index (DLQI) and visual analog scale (VAS) of pain, were reached at week 16. In 71.42% of patients DLQI and VAS of pain improved, irrespective of achievement of HiSCR. Two patients abandoned treatment due to lack of efficacy or patient preferences. No ustekinumab-related adverse effects were reported. The results are limited by the retrospective nature of the study, the short follow-up period, and the small patient number. This therapeutic regime proved to be safe and showed moderate efficacy in treating HS with failure to previous biologic therapy. Ideally, the efficacy of ustekinumab in HS should be tested in randomized and controlled clinical trials. [ABSTRACT FROM AUTHOR]

Topical imiquimod is a potential treatment for intra-anal condyloma and squamous intraepithelial lesions caused by human papillomavirus (HPV). We aimed to assess the effectiveness and tolerability of imiquimod suppositories for the treatment of anal high-grade intraepithelial lesions (HSIL) and condylomas in HIV-infected patients. We conducted a retrospective analysis in a prospectively followed cohort. High-resolution anoscopy was used for diagnosis and assessment following treatment. Patients' tolerability was assessed with a self-administered survey. Ninety-five patients (94.7% men) were analyzed. All were on combination antiretroviral therapy. Median CD4 T-cell count was 690 cells/µL, 89% had undetectable plasma viral load. Response to imiquimod was seen in 46.3% (complete: 12.5%, partial: 33.8%) in the intent-to-treat analysis, and in 55.2% (complete: 14.9%, partial: 40.3%) in the on-treatment analysis. Higher response rates were observed for anal condyloma compared with HSIL. A significantly poorer response rate was observed in smokers and in individuals with lower nadir CD4 T-cell counts. Imiquimod tolerability was "good" in 57.1% (n = 36), "acceptable" in 33.3% (n = 21), and "poor" in 9.5% (n = 6). Systemic side effects were reported in 20.7% (n = 13). There was no association between treatment effect and tolerability. In conclusion, imiquimod stands as a well-tolerated option for the treatment of HPV-associated intra-anal pathology in HIV-infected individuals. [ABSTRACT FROM AUTHOR]

Dear Editor, Cutaneous manifestations of coronavirus disease 2019 (COVID-19), including pseudo-chilblain, vesicular, maculopapular, urticaria, and livedo/necrosis1 lesions, have been widely reported. Other patients with COVID-19 and thrombotic events develop antiphospholipid antibodies, suggesting an antiphospholipid syndrome-like condition.5 Cemiplimab is a novel anti-PD-1 therapy recently approved for locally advanced or metastatic cutaneous SCC.

Pemphigus vulgaris is an infrequent but life-threatening autoimmune blistering disease that is rare in the pediatric age. Although the mainstay of therapy for childhood pemphigus vulgaris (CPV) is steroids, adjuvant immunosuppressive drugs are often needed to control the disease. Thus, an important part of CPV morbidity can be related to treatment. We report the youngest CPV patient described in the English literature, an 18-month-old boy, who has been followed up for 16 years. During this period, the patient has received several immunosuppressive therapies with variable response. He has finally achieved a long-lasting and complete remission with rituximab. Successful treatment with rituximab has previously been reported in 6 cases of CPV, in whom rituximab presented a good side effect profile. Our patient has experienced a chronic and severe clinical course with multiple flares eventually developing vegetative lesions. Since he presented refractoriness to multiple therapies, we administered rituximab. The introduction of this drug led to a dramatic clinical response and a long-term clinical remission. Based on the experience of this case and the data reported in the literature, we believe that rituximab may be a safe and efficacious agent for the treatment of severe CPV. Copyright © 2010 S.

There is growing interest in anal cancer screening strategies. However, cytological/molecular evaluation of anal samples is challenging. We aimed to determine the feasibility of detecting, in anal liquid-based cytologies, the expression of biomarkers involved in the cell cycle disturbance elicited by human papillomavirus (HPV). The accuracy of this approach in the identification of high-grade squamous intraepithelial lesions/anal intraepithelial neoplasia grade2–3 (HSIL/AIN2–3) was also evaluated. 215 anal cytologies from men having sex with men living with human immunodeficiency virus were evaluated. Patients showing concordant cytological and anoscopy-directed biopsy diagnosis were selected: 70 with negative cytology and HPV test, 70 with low-grade SIL (LSIL/AIN1) cytology and biopsy, and 75 with cytology and biopsy of HSIL/AIN2–3. CDKN2A/p16, MKI67 and TOP2A mRNA expression was analyzed. HPV detection was performed with Xpert HPV Assay (Cepheid, Sunnyvale, CA, USA). HSIL/AIN2–3 showed higher expression for the biomarkers than LSIL/AIN1 or negative samples. The specificity for HSIL/AIN2–3 detection for a sensitivity established at 70% was 44.7% (95%confidence interval [CI] 36.5–53.2) for TOP2A and MKI67 and 54.5% (95%CI 46.0–62.8%) for CDKN2A/p16. mRNA detection of cell biomarkers in anal liquid-based cytology is feasible. Further studies are warranted to confirm if strategies based on mRNA detection have any role in anal cancer screening. [ABSTRACT FROM AUTHOR]

Background and Objectives Methods Results Conclusions Survival analyses can provide valuable insights into effectiveness and safety as perceived by prescribers. Here, we aimed to evaluate adalimumab (ADA) survival and the interruption risk factors in a multicentre cohort of patients with hidradenitis suppurativa (HS). Moreover, we performed a subanalysis considering the periods before and after the onset of the COVID‐19 pandemic.We conducted a retrospective study including 539 adult patients with HS who received ADA from 1 May 2015 to 31 December 2022. Overall drug survival was analysed using Kaplan–Meier survival curves and compared between the subgroups via stratified log‐rank test. Possible predictors for overall drug survival and reasons for discontinuation were assessed using univariate and multivariate Cox regression.Overall, 50.1% were females with a mean age of 43.5 ± 1 years and a mean BMI of 29.5 ± 6.7. At the start of ADA, 95.29% were biologic‐naïve and 24.63% had undergone surgical treatment. During follow‐up, 9.46% of patients required dose escalation, while 39.92% interrupted ADA. Concomitant therapy was used in 64.89% of cases. A subanalyses comparing pre‐ and post‐pandemic periods revealed a tendency to initiate ADA treatment at a younger age, among patient with higher BMI and at a lower HS stage after COVID‐19 pandemic. Interestingly, ADA demonstrated extended survival compared to previous studies, with a median overall drug survival of 56.2 months (95% CI 51.2 to 80.3). The primary causes for discontinuation were inefficacy (51.69%), followed by adverse effects (21.35%). Female sex, longer delay in HS diagnosis, higher baseline IHS4 score and concomitant spondyloarthritis were associated with poorer ADA survival or increased risk of discontinuation.ADA demonstrated prolonged survival (median 56.2 months). While addition of antibiotics did not have a positive effect on survival rate, basal IHS4 proved useful in predicting ADA survival. [ABSTRACT FROM AUTHOR]

Since May, 2022, a large global outbreak of human mpox (formerly known as monkeypox) has predominantly affected men who have sex with men. The strain responsible, Clade IIb, has mutated substantially from precursors originating from the 2017–18 outbreak in Nigeria. Immunity to smallpox, another orthopoxvirus, via previous infection or vaccination provides lifelong immunity. However, since the 2022 mpox outbreak, recent clusters were described in individuals with presumed immunity through recent infection or vaccination. We aim to describe the epidemiological and clinical characteristics of mpox in individuals with past infection or vaccination to improve the understanding of this disease in the setting of previous immunity. In this global case series, international collaborators from nine countries provided data on individuals with PCR-confirmed mpox after documented previous infection or vaccination between May 11, 2022, and June 30, 2023. We excluded cases that could not confirm vaccination status or cases with partial immunisation or any doses received before the current multi-national mpox outbreak (cutoff date May 1, 2022). Data were collected via a case report spreadsheet that reported on dates of infection and vaccination, route of immunisation, demographic characteristics, clinical findings, HIV status, concomitant sexually transmitted infections, and markers of disease severity (mpox severity score system). We describe case epidemiology, clinical course, and mpox severity scores; all analyses were descriptive. We report mpox infections in 37 gay and bisexual men who have sex with men: seven individuals had mpox reinfections, 29 individuals had mpox infections that occurred after two appropriately spaced Modified Vaccinia Ankara-Bavarian Nordic vaccine courses, and one individual had an infection that met the criteria for both reinfection and infection after vaccination. The median age of individuals was 36 years (IQR 30–45; range 21–58). Those with natural immunity after initial infection had a shorter disease course with less mucosal disease upon reinfection than with their initial infection. Infections post-vaccination were characterised by few lesions, little mucosal disease, and minimal analgesia requirements; two people received oral tecovirimat. Overall, there were no deaths, no bacterial superinfections, and all individuals were managed in the ambulatory clinic with one hospital admission for a necrotising neck lesion. The epidemiology of people with mpox reinfection or infection post-vaccination was similar to other published cohorts during the 2022 outbreak—predominantly young, sexually active gay and bisexual men who have sex with men. Clinical features and outcomes of repeat infection and infection after vaccination appear to be less clinically severe than those described in 2022 case literature. Specifically, compared with the 2022 case series, these individuals in the present study had fewer confluent lesions, less mucosal involvement, reduced analgesia requirement, and fewer admissions. Natural immunity and vaccine-induced immunity are not fully protective against mpox infection. However, in this small series both disease duration and severity appear to be reduced. None.

Background: Since May 2022, a new outbreak of monkeypox has been reported in several countries, including Spain. The clinical and epidemiological characteristics of the cases in this outbreak may differ from those in earlier reports., Objectives: To document the clinical and epidemiological characteristics of cases of monkeypox in the current outbreak., Methods: We conducted a prospective cross-sectional study in multiple medical facilities in Spain to describe the cases of monkeypox in the 2022 outbreak., Results: In total, 185 patients were included. Most cases started with primarily localized homogeneous papules, not pustules, in the probable area of inoculation, which could be cutaneous or mucous, including single lesions. Generalized small pustules appeared later in some of them. Heterogeneous lesions occurred during this generalized phase. All patients had systemic symptoms. Less common lesions included mucosal ulcers (including pharyngeal ulcers and proctitis) and monkeypox whitlows. Four patients were hospitalized, none died. Smallpox vaccination and well-controlled HIV disease were not associated with markers of severity. Contact during sex is the most likely mechanism of transmission. In this outbreak, cases have been described in men who have sex with men and are strongly associated with high-risk sexual behaviours. Seventy-six per cent of the patients had other sexually transmitted diseases upon screening., Conclusions: The clinical findings in this outbreak differ from previous findings and highly suggest contact transmission and initiation at the entry site. The characterization of the epidemiology of this outbreak has implications for control. What is already known about this topic? Monkeypox eruption is described as consisting of pustules. The roles of HIV and previous smallpox vaccination in the prognosis are unknown. The transmission route was initially described as respiratory droplets and was later suggested to be via sexual contact. What does this study add? Initial lesions at the probable inoculation area were homogeneous and papular (pseudopustules). Generalized small pustules appeared later in some of them. Heterogeneous lesions occurred during this generalized phase. All patients had systemic symptoms. Less common signs included mucosal ulcers (including pharyngeal ulcers and proctitis) and monkeypox whitlows. Well-controlled HIV and previous smallpox vaccination were not associated with severity. No patient died. The data support the hypothesis of transmission via contact during sex. Although this might change, the outbreak is currently limited mostly to men who have sex with men, with high-risk factors for sexually transmitted diseases., (© 2022 British Association of Dermatologists.)

A monkeypox (MPX) outbreak has expanded worldwide since May 2022. We tested 147 clinical samples collected at different time points from 12 patients by real-time PCR. MPX DNA was detected in saliva from all cases, sometimes with high viral loads. Other samples were frequently positive: rectal swab (11/12 cases), nasopharyngeal swab (10/12 cases), semen (7/9 cases), urine (9/12 cases) and faeces (8/12 cases). These results improve knowledge on virus shedding and the possible role of bodily fluids in disease transmission.

Background: To date there are yet no available approved therapies for Geographic Atrophy (GA) secondary to age-related macular degeneration (AMD)., Methods: Single site, non-randomized safety and efficacy study presenting the preliminary results in a cohort of five late stage AMD (GA) patients successfully implanted with the Argus II Retinal Prosthesis System (Second Sight Medical Products Inc., Sylmar, CA, USA). Extensive fundus imaging including retinal photographs from which the GA area was measured. A combination of custom and traditional tests designed for very low vision subjects assessed visual function in study subjects. A Functional Low-Vision Observer Rated Assessment was carried out to evaluate the impact of the system on the subject's daily life. In addition, a study to evaluate structural characteristics of the visual cortex of the brain was performed in one subject using magnetic resonance imaging., Results: Seven device-related adverse events were reported, four of which were classed as serious adverse events. Retinal detachment was reported in three patients and was successfully treated within 12 months of onset. Testing showed an improvement in visual function in three of five patients with the system turned on. Magnetic resonance imaging assessed in one patient after implantation indicates a selective increase in cortical myelin and thickness in visual brain regions 1 year post implantation., Conclusions: Epiretinal prostheses can successfully be implanted in those affected by GA secondary to late-stage AMD and can elicit visual percepts by electrical stimulation of residual neuroretinal elements and improve basic visual function in those affected.

Background and Objective: In the last decade, the incidence of syphilis has increased in our health area. Our objective is to describe the epidemiological and clinical characteristics of patients diagnosed with syphilis at our centre and their relationship with HIV., Patients and Methods: The clinical and epidemiological variables of patients diagnosed with syphilis in a third-level hospital over a period of 4.5 years, as well as their HIV status, were analysed through a descriptive study., Results: There was a significant increase in the incidence of syphilis in the period 2011-2015. We included 220 patients, 98% men (94% MSM). 62% were HIV+ and 89% came in early/infectious stages of the disease. 7% were concomitantly diagnosed with HIV. There was a high number of sexual partners and frequent use of drugs associated with sexual activity (46%)., Conclusions: The incidence of syphilis has increased in our centre in the last 2 years. The most affected group is MSM, with high HIV prevalence and risk behaviours for STI acquisition., (Copyright © 2017 Elsevier España, S.L.U. All rights reserved.)
