Improving the Management and Follow-up of Atopic Dermatitis: A Delphi Process Report of Consensus Between Hospital Dermatologists and Pharmacists

[spa] El control de la dermatitis atópica (DA), una de las dermatosis más frecuentes, es en muchas ocasiones un reto terapéutico. En el presente estudio se ha utilizado la metodología Delphi con el objetivo de poner en común las perspectivas del dermatólogo y del farmacéutico hospitalario ante el manejo de la DA y establecer una serie de recomendaciones de actuación adaptadas a las diferentes situaciones que plantea la enfermedad. El cuestionario Delphi ha sido definido por un comité científico y se ha dividido en 2 bloques: (1) valoración de la respuesta al tratamiento del paciente con DA y (2) cooperación entre Dermatología y Farmacia Hospitalaria (FH). Como resultado del estudio, se ha alcanzado un consenso total del 86%. Se concluye que el dermatólogo y el farmacéutico hospitalario deben tener una buena comunicación y trabajar coordinados para conseguir optimizar el manejo del paciente con DA y su respuesta al tratamiento.[eng] Managing atopic dermatitis, one of the most common dermatologic conditions, is often challenging. To establish consensus on recommendations for responding to various situations that arise when treating atopic dermatitis, a group of hospital pharmacists and dermatologists used the Delphi process. A scientific committee developed a Delphi survey with 2 blocks of questions to explore the group's views on 1) evaluating response to treatment in the patient with atopic dermatitis and 2) cooperation between the dermatology department and the hospital pharmacy service. The experts achieved an overall rate of consensus of 86% during the process. Conclusions were that dermatologists and hospital pharmacists must maintain good communication and coordinate their interventions to optimize the management of atopic dermatitis and patients' responses to treatment

C9orf72-mediated ALS and FTD: multiple pathways to disease

The discovery that repeat expansions in the C9orf72 gene are a frequent cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) has revolutionized our understanding of these diseases. Substantial headway has been made in characterizing C9orf72-mediated disease and unravelling its underlying aetiopathogenesis. Three main disease mechanisms have been proposed: loss of function of the C9orf72 protein and toxic gain of function from C9orf72 repeat RNA or from dipeptide repeat proteins produced by repeat-associated non-ATG translation. Several downstream processes across a range of cellular functions have also been implicated. In this article, we review the pathological and mechanistic features of C9orf72-associated FTD and ALS (collectively termed C9FTD/ALS), the model systems used to study these conditions, and the probable initiators of downstream disease mechanisms. We suggest that a combination of upstream mechanisms involving both loss and gain of function and downstream cellular pathways involving both cell-autonomous and non-cell-autonomous effects contributes to disease progression

Infecciones de transmisión sexual (ITS) durante el estado de alarma por la pandemia de COVID-19 en España.

To describe changes in sexually transmitted infection (STI) diagnoses during the first wave of the COVID-19 pandemic in Spain. We collected demographic, chronological, and clinical data for all patients seen for a possible STI at Hospital La Paz, Centro Sanitario Sandoval, and Centro de Diagnóstico Médico in Madrid and Hospital Costa del Sol in Malaga between March 14, 2020 and June 30, 2020. We identified 674 STI diagnoses. The median age of the patients was 33 years. Most cases were observed among people aged 30 to 40 years and among men who have sex with men. The most common diagnoses were proctitis (36.5%), syphilis (16%), nongonococcal (13.3%) and gonococcal (11.3%) urethritis, genital herpes (8.8%), vulvovaginitis/cervicitis (8.3%), and genital warts (4.2%). A microbiologically confirmed diagnosis was on record for 77% of cases. The main microorganisms identified were Chlamydia trachomatis (35.7%), Neisseria gonorrhoeae (31.4%) and Treponema pallidum (17.2%). The number of STI diagnoses increased after the easing of lockdown restrictions, which resulted in greater freedom of movement and more consultations. On comparing the 2019 and 2020 STI registries from Centro Sanitario Sandoval and Hospital La Paz for the period March to June, we observed reductions (of up to 81%) in all STI diagnoses. Physical distancing and movement restrictions appear to have resulted in a reduction in the incidence of STIs, although these measures did not completely eliminate sexual risk behaviors

Cyclohexene-fused 1,3-oxazines with selective antibacterial and antiparasitic action and low cytotoxic effects

Oxazine derivatives, a class of heterocyclic compounds, exhibit a variety of biological properties, such as anticonvulsant and antitumor activities. In this study, we evaluated the effect of two cyclohexene-fused 1,3-oxazines (cis‑1-benzyl-N-phenyl-1,4,4a,5,8,8a-hexahydro-3,1-benzoxazin-2-imine (1) and trans‑N-phenyl-1,4,4a,5,8,8a-hexahydro-3,1-benzoxazin-2-imine (2)) in cultures of Bacillus cereus, Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae, Salmonella enterica, Serratia marcescens, Shigella flexneri and Staphylococcus aureus by the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC). Additionally, the ex vivo antiparasitic activity of oxazines was assessed against Schistosoma mansoni, a helminth that is one of the major agents of the disease schistosomiasis Also, oxazines were evaluated on three tumor cell lines, NCI-H292 (human lung carcinoma), MCF-7 (human breast adenocarcinoma) and HEp-2 (human cervix carcinoma), and two normal cell lines (Vero and red blood cells). Bioassays revealed that oxazine 2 is more effective against bacteria than oxazine 1, with the lowest MIC and MBC values of 3.91 and 32.5 μg/mL, respectively. Similarly, compound 2 demonstrated higher antiparasitic activity than 1, and scanning electron microscopy analysis showed several morphological alterations in the tegument of worms in a concentration-dependent manner. In contrast, both oxazines exhibited low cytotoxic effects on cancer and normal cell lines. These results indicated that oxazines exerted direct effects on bacteria and parasite schistosomes. More importantly, since schistosomiasis control programs rely on one drug, praziquantel, oxazines may have the potential to become new antischistosomal agents.Fil: de Brito, Maria R.M..

A Systematic Review on Surgical Treatments for Sulcus Vocalis and Vocal Fold Scar

OBJECTIVES/HYPOTHESIS: Vocal fold sulcus and scars are benign vocal fold lesions that present as a challenge to the laryngologist. A number of different surgical techniques have been proposed, aiming at restoring the lamina propria (LP), closing the glottal gap, or both. This study aimed to provide a systematic review of surgical treatment for sulcus and scar and to propose a new classification for these techniques. STUDY DESIGN: A literature search using MEDLINE and Google Scholar through August 2020. METHODS: Data on study design were retrieved and outcomes were classified as acoustic, aerodynamic, self-reported, perceptual, and stroboscopic. Methodological quality was assessed using the MINORs criteria. Each technique was classified as direct, indirect, or combined. RESULTS: Our search included 31 studies with a total of 617 patients. Direct techniques included dissection, graft interposition, or LP regeneration/scar degradation while indirect techniques aimed for glottal gap closure. Only one article performed a comparison between different types of techniques and only eight studied the five types of outcomes. No superiority of any technique was noted in our analysis. Self-reported outcomes were the most frequently improved. CONCLUSIONS: There seems to not exist a one-fits-all treatment for this clinical picture and no clear decision-making pattern. A recent trend toward sequential approaches, starting with less invasive procedures, can be observed. Laryngoscope, 132:822-830, 2022
