RESUMEN

BACKGROUND: Several studies support the hypothesis that scabies is on the rise in Spain. There are also concerns about the possible development of resistance to treatment and an increase in atypical presentations. The aims of this study were to describe the demographic and clinical characteristics of patients with scabies seen by dermatologists in Spain, to identify the possible emergence of atypical forms of scabies, and to explore the frequency of treatment failures and associated risk factors. METHODS: We conducted an observational, cross-sectional, multicenter study of data collected prospectively in April and May 2023 using the CLINI-AEDVp platform created by the Spanish Academy of Dermatology and Venereology (AEDV). RESULTS: Participating dermatologists from 31 hospitals in 15 of Spain's autonomous communities recorded 186 cases of active scabies (51% in women) during the study period. A diagnostic certainty level of A, B or C as per the International Alliance for the Control of Scabies Consensus Criteria was required for diagnosis. Overall, 92% of patients had typical scabies and 66% had already been treated with a scabicide for the current episode. Of the treated patients, only 36% had received and completed adequate treatment (including the simultaneous treatment of all household members) and 50% had not received clear written recommendations. CONCLUSIONS: In a high proportion of the cases of scabies studied, the patient had already received treatment. In those cases, we observed several remediable shortcomings that could explain why some of these treatments had failed. Remedying these deficiencies should lead to better control of scabies and an improved assessment of the actual effectiveness of currently available scabicides.

A diagnostic certainty level of A, B or C as per the International Alliance for the Control of Scabies Consensus Criteria was required for diagnosis. Overall, 92% of patients had clinical features of classic scabies and 66% had already been treated with a scabicide for the current episode. Of the treated patients, only 36% had received and completed adequate treatment (including the simultaneous treatment of all household members) and 50% had not received clear written recommendations. CONCLUSIONS: In a high proportion of scabies cases, the patient has already received treatment. In those cases, we observe several remediable shortcomings that could explain why some of these treatments fail.

RESUMEN

Sexually transmitted infections are communicable diseases where the pathogen is transmitted through sexual contact. The Sexually Transmitted Infections Working Group of the Spanish Academy of Dermatology and Venereology (AEDV) is engaged in the drafting of documents to guide dermatologists and health care personnel who treat Spanish patients with these infections. This document analyzes the epidemiological, clinical, therapeutic, and control characteristics of 2 sexually transmitted parasitosis: scabies due to Sarcoptes scabiei var. hominis, and pubic pediculosis due to Phthirus pubis. Both parasitoses share a sort of mixed spread through sexual and community transmission regardless of the route through which the infection was initially acquired. This specific feature creates particularities in the management and control of the infestation.

RESUMEN

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.

RESUMEN

Vaccines against the severe acute respiratory coronavirus 2, which are the first to be used in humans against any coronavirus, were developed and produced in record time. Dermatologic adverse effects appeared during clinical trials and have also been described in the population since approval. Just as descriptions and categorization of skin manifestations of the coronavirus disease 2019 proved important for understanding the disease itself, characterizing the effects of vaccines may also further that goal. This paper reviews the properties of the different types of vaccines currently available and under development and describes how they interact with the immune system and the clinical signs they may cause. We focus on dermatologic adverse effects reported to date and recommendations for managing them.


Las vacunas contra el SARS-CoV-2 son las primeras vacunas que han sido usadas en humanos contra coronavirus y su desarrollo se ha producido en un tiempo récord. En los análisis de seguridad de los ensayos clínicos previos a su aprobación y en la fase postautorización en la población, se han descrito efectos secundarios dermatológicos. La descripción y categorización de las manifestaciones cutáneas de la COVID-19 fueron importantes para el conocimiento de la enfermedad y de la misma forma pueden serlo las generadas por las vacunas. En este artículo hacemos un repaso a las características de los diferentes tipos de vacunas disponibles y en desarrollo, su modo de interacción con el sistema inmune, las consecuentes manifestaciones clínicas que pueden generar, con especial interés en los efectos secundarios dermatológicos hasta el momento descritos, y las actitudes terapéuticas recomendadas ante cada una de estas reacciones.

RESUMEN

BACKGROUND AND OBJECTIVES: Epidemiologic and disease burden data are essential for disease control and optimal health care resource planning. The aims of this study were to estimate the epidemiologic burden of psoriasis and evaluate associated comorbidities, health care utilization, and sick leave. MATERIAL AND METHODS: We collected data from the 2016 Catalan Health Survey (ESCA), the Catalan Registry of Morbidity and Utilization of Health Care Services (MUSSCAT) (2016), and the database of the Catalan Medical Evaluations Institute (ICAM) (2012-2016). RESULTS: The prevalence of psoriasis in Catalonia according to 2016 ESCA data is approximately 1.8%. The MUSSCAT registry data indicate that the incidence has remained stable in recent years. The most common comorbidities associated with psoriasis are hypertension (35%) and diabetes (15%). Forty percent of patients with psoriasis have a moderate to high risk for death or high health resource utilization. Annual use of resources by psoriasis patients is high: they make a mean of 8.7 primary care visits, 2.8 outpatient visits, 0.5 emergency and day hospital visits, 0.2 mental health visits, and use 6.1 medications. Sick leave due to psoriasis or psoriatic arthritis accounted for 0.04% of all cases. CONCLUSIONS: The prevalence of psoriasis in Catalonia is high at 1.8%. The disease burden is also high, both in terms of comorbidities and health care utilization.

RESUMEN

Drago et al. are right to point out that our paper did not provide data on enanthems.1,2 As the data collection form did not include the description of mucous membranes, they might not have been explored in many patients. We have reported and included in the supplementary material a few cases that were noticed by their doctors and were the first descriptions of enanthem in COVID-19. Given the low number of cases and their nonsystematic acquisition, we avoided any analysis of these data.

RESUMEN

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.

RESUMEN

Mucopolysaccharidosis (MPS) type VII is a lysosomal storage disease caused by ß-glucuronidase deficiency, prompting glycosaminoglycan accumulation in enlarged vesicles, leading to peripheral and neuronal dysfunction. Here, we present a gene therapy strategy using lumbar puncture of AAVrh10 encoding human ß-glucuronidase (AAVrh10-GUSB) to adult MPS VII mice. This minimally invasive technique efficiently delivers the recombinant vector to the cerebrospinal fluid (CSF) with a single intrathecal injection. We show that AAVrh10 delivery to the CSF allows global, stable transduction of CNS structures. In addition, drainage of AAVrh10-GUSB from the CSF to the bloodstream resulted in the transduction of somatic organs such as liver, which provided a systemic ß-glucuronidase source sufficient to achieve serum enzyme activity comparable to wild type mice. ß-glucuronidase levels were enough to correct biochemical and histopathological hallmarks of the disease in the CNS and somatic organs at short and long term. Moreover, the progression of the bone pathology was also reduced. Importantly, the biochemical correction led to a significant improvement in the physical, cognitive and emotional characteristics of MPS VII mice, and doubling their life span. Our strategy may have implications for gene therapy in patients with lysosomal storage diseases.

RESUMEN

BACKGROUND: In a significant percentage of advanced non-small-cell lung cancer (NSCLC) patients, tumor tissue is unavailable or insufficient for genetic analyses. We prospectively analyzed if circulating-free DNA (cfDNA) purified from blood can be used as a surrogate in this setting to select patients for treatment with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). PATIENTS AND METHODS: Blood samples were collected in 119 hospitals from 1138 advanced NSCLC patients at presentation (n = 1033) or at progression to EGFR-TKIs (n = 105) with no biopsy or insufficient tumor tissue. Serum and plasma were sent to a central laboratory, cfDNA purified and EGFR mutations analyzed and quantified using a real-time PCR assay. Response data from a subset of patients (n = 18) were retrospectively collected. RESULTS: Of 1033 NSCLC patients at presentation, 1026 were assessable; with a prevalence of males and former or current smokers. Sensitizing mutations were found in the cfDNA of 113 patients (11%); with a majority of females, never smokers and exon 19 deletions. Thirty-one patients were positive only in plasma and 11 in serum alone and mutation load was higher in plasma and in cases with exon 19 deletions. More than 50% of samples had <10 pg mutated genomes/µl with allelic fractions below 0.25%. Patients treated first line with TKIs based exclusively on EGFR positivity in blood had an ORR of 72% and a median PFS of 11 months. Of 105 patients screened after progression to EGFR-TKIs, sensitizing mutations were found in 56.2% and the p.T790M resistance mutation in 35.2%. CONCLUSIONS: Large-scale EGFR testing in the blood of unselected advanced NSCLC patients is feasible and can be used to select patients for targeted therapy when testing cannot be done in tissue. The characteristics and clinical outcomes to TKI treatment of the EGFR-mutated patients identified are undistinguishable from those positive in tumor.

RESUMEN

Antiretrovirals are a significant cost driver for HIV programmes. Current first-line regimens have performed well in real-life programmes, but have a low barrier to virological resistance and still carry toxicity that limits adherence. New drug developments may mean that we have access to safer, more robust and cheaper regimens, but only if the appropriate clinical trials are conducted. We briefly discuss these trials, and demonstrate the large cost savings to the South African HIV programme if these are successful.

RESUMEN

Lactococcus garvieae is a Gram-positive, catalase negative coccus arranged in pairs or short chains, well-known as a fish pathogen. We report a case of Infective Endocarditis (IE) by L. garvieae in a native valve from a 68-year-old male with unknown history of contact with raw fish and an extensive history of heart disease. This case highlights the reliability of MALDI-TOF MS compared to conventional methods in the identification of rare microorganisms like this.

RESUMEN

Challenging behaviors exhibited by individuals with developmental disabilities often hinder the acquisition of academic, social, and life skills. Functional analysis has been useful for assessing challenging behavior in various settings. The purpose of this study was to implement an operant methodology for recognizing the functional properties of challenging behavior in people with intellectual disabilities. Four adults diagnosed with profound intellectual disability received assessment under several experimental conditions using a functional analysis methodology: social attention as positive reinforcement, negative reinforcement such as the termination of demands, positive tangible reinforcements, absence of social contingencies, and escape from noisy stimuli. Results showed that different types of reinforcement or avoiding contingencies affected the rate of aggression, self-injury, disruption, stereotypy, or socially offensive behaviors, and functional analysis may potentially be a viable alternative for identifying challenging behaviors.
