RESUMEN
BACKGROUND: Tumor necrosis factor α (TNF) inhibitors are used to treat different inflammatory diseases. Although these biologics have an adequate safety profile, they have been associated with paradoxical reactions. MATERIAL AND METHODS: Retrospective review of patients on TNF inhibitor therapy who developed a paradoxical skin reaction and were seen at the dermatology department of Hospital Universitari Parc Taulí in Sabadell, Spain. RESULTS: We collected data on 30 patients under treatment with a TNF inhibitor who developed an immune-mediated skin reaction in the form of psoriasis (90%), alopecia (6.7%), or neutrophilic dermatitis (3.3%). The most common drugs involved were adalimumab (56.7%) and infliximab (40%). Psoriasiform reactions mostly manifested as generalized plaques (62.9%) or palmoplantar pustulosis (37%). Thirteen patients (43.3%) continued on the same TNF inhibitor and 12 of them (92.3%) achieved partial or complete resolution of lesions. Five patients were switched to a different TNF inhibitor, but none of them achieved complete resolution. Eight patients were switched to a biologic with a different target, and 5 of them (62.5%) achieved partial or complete resolution. CONCLUSIONS: Paradoxical reactions during TNF inhibitor therapy do not always require a change of treatment. In our series, the addition of a topical and/or systemic treatment resolved the skin lesions in more than half of the patients, and switching to a drug with a different target was more effective. A change of strategy should be contemplated in more serious cases.

BACKGROUND: In 2013, Canoui-Poitrine et al. identified three hidradenitis suppurativa (HS) phenotypes by a latent class (LC) analysis, based on anatomical sites of involvement. OBJECTIVE: To improve the classification of the gluteal phenotype (LC3) patients given their diverse lesion types and differences in clinical profile. MATERIAL AND METHODS: We designed a bicentric study gathering all LC3 patients (n=83) from two hospitals. We conducted a two-step cluster analysis among them and also compared their characteristics with the rest of the HS patients (n=661). RESULTS: Compared with global HS series, LC3 patients were more frequently non-obese men, with smoking habit, an associated arthropathy, and a more frequent history of pilonidal sinus. The analysis of LC3 patients yielded two clusters: cluster 1 (38.3%) included elderly female patients, with later diagnosis of the disease and more sinus tracts; cluster 2 (61.7%) encompassed more men with earlier disease onset and more nodules and folliculitis lesions. LIMITATIONS: The study's limitations include its retrospective nature, bicentric design, and small sample size. CONCLUSION: The heterogeneous clinical presentation of HS makes it essential to have a good classification of the patients. Gluteal phenotype could actually be classified into two "subphenotypes" with a different clinical profiles and management.

BACKGROUND: Reconstruction of surgical defects located close to eyelid edges, nostrils, or the mouth is challenging, as tension generated by direct closure or skin flaps in these sensitive regions tends to cause distortion. New repair techniques that prevent retraction may significantly improve outcomes. PATIENTS AND METHODS: Retrospective study of the use of 2 novel flap designs-the nautilus flap and the bullfighter crutch flap-to repair surgical defects in the peripalpebral, perivestibular, nasal, and perioral areas. The nautilus flap was used to repair 4 peripalpebral defects and 2 perioral defects, and the bullfighter crutch flap to repair 14 nasal ala defects. RESULTS: Cosmetic and functional outcomes were very satisfactory in all 20 patients, with no cases of ectropion, nasal vestibule collapse, or labial asymmetry. Necrosis did not occur in any of the cases. CONCLUSIONS: The nautilus and bullfighter crutch flaps appear to be excellent choices for reconstructing surgical defects in periorificial areas.

BACKGROUND: The reconstruction of surgical defects in high-tension anatomical regions is challenging due to the ischemia and subsequent necrosis associated with tension closure. Research on new flaps capable of closing these defects exerting less tension would be a tremendous advancement in dermatological surgery. PATIENTS AND METHODS: We conducted a multicenter, retrospective study that used 2 new flaps-the bishop and the sigma ones-to repair surgical defects in high-tension regions such as the scalp, lower extremities, and the nasal pyramid. The bishop flap was used in 9 patients, 5 of whom exhibited their lesion in the nasal pyramid, 2 in the legs and another 2 in the scalp. The sigma flap was used in 6 patients, 5 of whom exhibited scalp lesions and 1 leg lesion. RESULTS: Uneventful and excellent results were obtained in all 15 patients due to infection, dehiscence, or necrosis. CONCLUSIONS: Both the bishop and the sigma flaps are a good alternative to repair surgical defects in high-tension regions such as the scalp, lower extremities, or the nasal pyramid.
RESUMEN
BACKGROUND: Hidradenitis suppurativa (HS) is a chronic skin condition causing lesions in which high levels of interleukin (IL)-23 and T-helper17 cells are found. Adalimumab remains the only approved treatment. Guselkumab, an antibody targeting the p19 protein subunit of extracellular IL-23, is approved for the treatment of moderate-severe psoriasis, but evidence on its efficacy in treating HS is limited. OBJECTIVES: To assess the effectiveness and safety of guselkumab in treating moderate-severe HS under clinical practice conditions. METHODS: A multicentre retrospective observational study was carried out in 13 Spanish hospitals including adult HS patients treated with guselkumab within a compassionate use programme (March 2020-March 2022). Data referred to patient demographic and clinical characteristics at treatment initiation (baseline), patient-reported outcomes (Numerical Pain Rating Scale [NPRS] and Dermatology Life Quality Index [DLQI]), physician scores (International Hidradenitis Suppurativa Severity Score System [IHS4], HS Physical Global Score [HS-PGA] and Hidradenitis Suppurativa Clinical Response [HiSCR]) were recorded at baseline and at 16, 24, and 48weeks of treatment. RESULTS: A total of 69 patients were included. Most (84.10%) had severe HS (HurleyIII) and had been diagnosed for over ten years (58.80%). The patients had been subjected to multiple non-biological (mean: 3.56) or biological (mean: 1.78) therapies, and almost 90% of those treated with biologics had received adalimumab. A significant decrease in IHS4, HS-PGA, NPRS, and DLQI scores was observed from baseline to 48weeks of guselkumab treatment (all P<.01). HiSCR was achieved in 58.33% and 56.52% of the patients at 16 and 24weeks, respectively. Overall, 16 patients discontinued treatment, mostly due to inefficacy (n=7) or loss of efficacy (n=3). No serious adverse events were observed. CONCLUSIONS: Our results indicate that guselkumab may be a safe and effective therapeutic alternative for patients with severe HS that fail to respond to other biologics.

INTRODUCTION: Since 2021, an increase in cases of tinea capitis has been detected in adolescents who shave their hair with fade haircut. PATIENTS AND METHODS: Multicenter retrospective observational study of cases of cephalic pole dermatophytosis with a history of having been acquired after frequent shaving in hairdressing. A call was made to dermatologists from the Spanish Academy of Dermatology and Venereology (AEDV) to provide cases observed between January 2021 and December 2022. Patients with microbiological confirmation by culture or direct examination with KOH were included. RESULTS: 107 cases were collected, 106 of which were male. 78 non-inflammatory forms were observed, compared to 29 inflammatory. The most frequently isolated fungus was Trichophyton tonsurans (75.7% of cases). The lesions appeared predominantly on the nape of the neck and temporal area. CONCLUSIONS: The distribution by sex, age and lesional location seems to indicate that a new social trend, in which male adolescents regularly go to hairdressers to shave the occipital and temporal areas, would be the cause of this grouping of cases of ringworm of the scalp. The most frequent microorganism in our study (T.tonsurans) coincides with the most prevalent in our environment. This study shows an accumulation of cases that can be taken into account by competent Public Health agencies, which are responsible for ensuring compliance with the rules of disinfection of the material used for shaving.

BACKGROUND: Cutaneous reactions after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines are poorly characterized. OBJECTIVE: To describe and classify cutaneous reactions after SARS-CoV-2 vaccination. METHODS: A nationwide Spanish cross-sectional study was conducted. We included patients with cutaneous reactions within 21 days of any dose of the approved vaccines at the time of the study. After a face-to-face visit with a dermatologist, information on cutaneous reactions was collected via an online professional survey and clinical photographs were sent by email. Investigators searched for consensus on clinical patterns and classification. RESULTS: From 16 February to 15 May 2021, we collected 405 reactions after vaccination with the BNT162b2 (Pfizer-BioNTech; 40·2%), mRNA-1273 (Moderna; 36·3%) and AZD1222 (AstraZeneca; 23·5%) vaccines. Mean patient age was 50·7 years and 80·2% were female. Cutaneous reactions were classified as injection site ('COVID arm', 32·1%), urticaria (14·6%), morbilliform (8·9%), papulovesicular (6·4%), pityriasis rosea-like (4·9%) and purpuric (4%) reactions. Varicella zoster and herpes simplex virus reactivations accounted for 13·8% of reactions. The COVID arm was almost exclusive to women (95·4%). The most reported reactions in each vaccine group were COVID arm (mRNA-1273, Moderna, 61·9%), varicella zoster virus reactivation (BNT162b2, Pfizer-BioNTech, 17·2%) and urticaria (AZD1222, AstraZeneca, 21·1%). Most reactions to the mRNA-1273 (Moderna) vaccine were described in women (90·5%). Eighty reactions (21%) were classified as severe/very severe and 81% required treatment. CONCLUSIONS: Cutaneous reactions after SARS-CoV-2 vaccination are heterogeneous. Most are mild-to-moderate and self-limiting, although severe/very severe reactions are reported. Knowledge of these reactions during mass vaccination may help healthcare professionals and reassure patients.

BACKGROUND: Childhood obesity represents a global public health crisis: the number of obese children and adolescents (aged 5-19 years) worldwide has risen tenfold in the past four decades. The vast majority of overweight and obese children live in high-income countries, and low socio-economic status (SES) is a significant risk factor. Family Based Interventions (FBI) have demonstrated positive results in preventing obesity, although these results are strongly influenced by SES. Moreover, we still poorly understand how FBI can determine a positive trend in weight status in low-income communities. Therefore, there is an urgent need to define and evaluate innovative and multi-target projects to reduce obesity risk behaviors and health inequalities and the present study aims to present the study protocol of FIVALIN a FBI that pretends to achieve this goal. METHODS: We will conduct a quasi-experimental design within 60 Community Child Centers (CCC) in Barcelona metropolitan area. Each cluster (CCC) will be assigned by convenience to the intervention and control groups. For the whole study, a total of 810 children aged 8-12 years and 600 parents will be recruited during 3 consecutive editions (1st - 2019/2020; 2nd - 2020/2021; 3rd - 2021/2022) of 10 months each. The action is a regular multicomponent health-promotion intervention targeting children, families, and CCC. All activities are based on the Motivational Interviewing (MI) approach and will focus on promoting good dietary habits, physical activity, appropriate screen time and sleep duration, and psychological well-being. The control group participate in a unique workshop on general awareness of healthy lifestyles for families. We will perform a comparative analysis of the evolution of weight status, healthy lifestyles, and socioeconomic variables, between the intervention and control groups. DISCUSSION: There is a need for more evidence on how to target and evaluate holistic interventions in low SES families. Our multi-targeting intervention for obesity prevention tackles risky behaviors that go beyond diet and physical activity (PA). Therefore, future interventions can effectively promote all the behavioral domains that determine trends in the weight status. TRIAL REGISTRATION: ISRCTN Registry: ISRCRN12682870 .

BACKGROUND: The cutaneous manifestations of COVID-19 disease are poorly characterized. OBJECTIVES: To describe the cutaneous manifestations of COVID-19 disease and to relate them to other clinical findings. METHODS: We carried out a nationwide case collection survey of images and clinical data. Using a consensus we described five clinical patterns. We later described the association of these patterns with patient demographics, the timing in relation to symptoms of the disease, the severity and the prognosis. RESULTS: The lesions may be classified as acral areas of erythema with vesicles or pustules (pseudo-chilblain) (19%), other vesicular eruptions (9%), urticarial lesions (19%), maculopapular eruptions (47%) and livedo or necrosis (6%). Vesicular eruptions appear early in the course of the disease (15% before other symptoms). The pseudo-chilblain pattern frequently appears late in the evolution of the COVID-19 disease (59% after other symptoms), while the rest tend to appear with other symptoms of COVID-19. The severity of COVID-19 shows a gradient from less severe disease in acral lesions to more severe in the latter groups. The results are similar for confirmed and suspected cases, in terms of both clinical and epidemiological findings. Alternative diagnoses are discussed but seem unlikely for the most specific patterns (pseudo-chilblain and vesicular). CONCLUSIONS: We provide a description of the cutaneous manifestations associated with COVID-19 infection. These may help clinicians approach patients with the disease and recognize cases presenting with few symptoms. What is already known about this topic? Previous descriptions of cutaneous manifestations of COVID-19 were case reports and mostly lacked illustrations. What does this study add? We describe a large, representative sample of patients with unexplained skin manifestations and a diagnosis of COVID-19, using a consensus method to define morphological patterns associated with COVID-19. We describe five clinical patterns associated with different patient demographics, timing and prognosis, and provide illustrations of these patterns to allow for easy recognition.

Hidradenitis suppurativa and inflammatory bowel disease are chronic inflammatory diseases mainly affecting young people. Their aetiology is complex and multifactorial and numerous case series have shown that the two diseases can manifest concurrently, although the strength of this association varies widely among distinct reports. An additional problem is the difficulty of distinguishing between cutaneous Crohn disease and hidradenitis. In the last few years, epidemiological cohort studies have revealed that 1.2%-23% of inflammatory bowel disease patients also have hidradenitis suppurativa. This wide variability is influenced by geographical variables and the biases inherent in the distinct data collection methods, among other factors. There is a clear predominance of Crohn disease over ulcerative colitis. When hidradenitis suppurativa and inflammatory bowel disease manifest concurrently, the bowel disease is more severe and shows a predominance of colon involvement.

Neutrophilic eccrine hidradenitis (NEH) is a nonspecific clinicopathological reaction pattern, classified as a neutrophilic dermatosis, that usually develops in patients receiving chemotherapy for a hematologic malignancy. More rarely, it has been reported in association with infectious agents such as Serratia and Enterobacter species, Staphylococcus aureus, and human immunodeficiency virus. We describe 3 cases of infectious eccrine hidradenitis secondary to infection with Nocardia species, Mycobacterium chelonae, and S aureus. Histological findings revealed a dense infiltrate with perivascular and periductal neutrophils in the dermis. In the eccrine glands, there was vacuolar degeneration and necrosis of the epithelial cells. Our cases support the assertion that NEH is a characteristic cutaneous response to nonspecific stimuli. Clinical and histopathological findings of infectious and noninfectious NEH are generally indistinguishable and when NEH is suspected, the possibility of an infectious association must be investigated by skin tissue culture. In this article we also discuss differential diagnoses and review the literature.

INTRODUCTION AND OBJECTIVES: Up to 30% of patients with psoriasis develop joint disease, the course of which can be improved by early diagnosis and treatment. The aim of this study was to describe our experience with a new multidisciplinary psoriasis and psoriatic arthritis unit over a period of 4 years (2009-2012). MATERIAL AND METHODS: Implementation of a PSOriasis Rheumatology and Dermatology unit (PSORD) to provide patient care and physician training. In the first phase of the project, referral criteria for the unit were defined and several meetings were organized to train and prepare the specialists involved in the program. In the second phase, a schedule was drawn up for monthly patient visits with the PSORD team. Starting in 2011, training was offered to dermatologists and rheumatologists from other hospitals interested in implementing a similar model. RESULTS: A total of 259 visits (71% first visits, 8% no-shows) were scheduled during the period analyzed, with a median of 8 visits (range, 2-14 visits) per session. Sixty-three percent of the patients were referred from the rheumatology department. Diagnosis and treatment were modified in 32% and 47% of cases, respectively. Three training courses were held with 15 physicians from 6 hospitals, 3 of which created similar units. CONCLUSIONS: The PSORD model improved the management of difficult-to-diagnose and/or uncontrolled disease, the early diagnosis and treatment of psoriatic arthritis, and collaboration between dermatologists and rheumatologists. Finally, the model lends itself to being exported to other settings.

Lipopolysaccharide-binding protein (LBP) is a reliable indicator of serum lipopolysaccharide (LPS) concentration. Raised levels of circulating LPS can trigger an increase in chronic pro-inflammatory cytokines, which may mediate the development of insulin resistance and obesity. Psoriasis is a chronic inflammatory skin disease that has been associated with metabolic syndrome. We aimed to study the expression of LBP in patients with psoriasis treated with narrowband ultraviolet B phototherapy, and controls matched by age, gender and body mass index (BMI). We did not find any differences in serum LBP concentration between patients and controls, and serum LBP did not correlate with the Psoriasis Area and Severity Index. However, patients with psoriasis and metabolic syndrome had higher serum concentration of LBP than controls. Furthermore, correlation with BMI and apolipoprotein B was present in controls, but not in patients with psoriasis. Serum LBP level did not change significantly after treatment with phototherapy.

BACKGROUND: Previous studies have shown increased prevalence of metabolic syndrome in patients with psoriasis. OBJECTIVES: To characterize the anthropometric and metabolic profile of Spanish patients with moderate to severe psoriasis compared with controls without psoriasis matched for gender, age and body mass index (BMI), and to evaluate the impact of narrowband ultraviolet B (NB-UVB) therapy on patient profiles. METHODS: Baseline waist circumference, body fat composition, lipid, carbohydrate and calcium metabolism profile, inflammation markers, homocysteine, vitamins D, B(6) and B(12) and folic acid of 50 patients with psoriasis and 50 matched controls were recorded then evaluated after NB-UVB in patients with psoriasis and correlated with clinical outcome. RESULTS: Despite very similar BMIs, 54% of patients met International Diabetes Foundation criteria for metabolic syndrome compared with 42% of controls (P = 0·01); body fat was 29·9% in patients and 28·0% in controls (P = 0·037), correlating with waist circumference; while patient atherogenic profiles were less favourable, with higher apolipoprotein B and low density lipoprotein cholesterol than controls, and both patients and controls showed insufficient vitamin D serum levels (< 20 ng mL(-1)). Mean improvement of Psoriasis Area and Severity Index (PASI) after NB-UVB was 78·2%. Ferritin, B(12) and C-reactive protein decreased significantly after NB-UVB therapy. Vitamin D levels reached adequate levels after phototherapy; however, no relationship with PASI improvement was observed. CONCLUSIONS: We characterized inflammatory and atherogenic profiles of Spanish patients with psoriasis compared with matched controls. After NB-UVB therapy we demonstrated improvement in psoriasis and some systemic inflammation markers, which were not mediated by enhancement of vitamin D synthesis.
