Métodos: Revisão dos pedidos de colaboração realizados ao serviço de IA entre janeiro de 2018 a junho de 2019, através da consulta dos processos clínicos dos doentes, com colheita de dados demográficos, motivo de internamento e do pedido de colaboração, diagnóstico imunoalergológico e orientação. Resultados: Foram identificados 177 pedidos de colaboração correspondentes a 157 internamentos de doentes com idade entre os 7 meses e os 89 anos, 52% dos quais do sexo feminino. Os pedidos mais frequentes resultaram da suspeita de reação de hipersensibilidade a fármacos (83%), seguido de pedidos para apoio na decisão terapêutica e exacerbação de asma. Os 177 pedidos originaram 446 visitas médicas de IA a internamentos (média de 2,6 visitas/ /doente). A suspeita de hipersensibilidade a fármacos foi confirmada em 64% dos casos, com diagnóstico de reações cutâneas graves em 19% e anafilaxia em 6%. A taxa de mortalidade foi de 5,1%, e 46,2% foram posteriormente avalia

Many patients believe they have MCAS, but how often this is the case remains unknown.MethodsWe prospectively investigated patients with suspected MCAS (n = 100) for the diagnostic criteria including baseline tryptase, KIT D816V mutation, and patient‐reported outcome measures (PROMs) over the course of 12 weeks. Comorbid depression and anxiety were explored with the Hospital Anxiety and Depression Scale (HADS).ResultsIn 53% of our patients (80% females), suspicion of MCAS was based on self‐evaluation. In total, patients reported 87 different symptoms, mostly fatigue (n = 57), musculoskeletal pain/weakness (n = 49), and abdominal pain (n = 43), with overall high dise...

However, swimming pools contain chlorine and other irritating chemicals that may induce contact dermatitis. To evaluate the effect of a swimming training session on transepidermal water loss (TWEL) in swimmers compared to football players, elite swimmers and football players were invited to participate (58 athletes) in the study, where TEWL was measured before, immediately after, and 30 min after a 2 h training session. The probe was held on the dorsum of the hand, volar forearm, and on the antecubital flexure for 1 min. The volar forearm, antecubital flexure, and hand dorsum showed a significant increase in TEWL in swimmers in both measurements after training compared to baseline (p < 0.001). In football players, an increase in TEWL was observed on the hands’ dorsum between baseline and after training measurements. The variations on TEWL levels before and immediately after the training session were higher among swimmers on...

These eruptions are diverse but are typically characterized by moderate-to-severe involvement of at least two mucosal sites and sparse or even absent skin involvement. Recently, mycoplasma-induced rash and mucositis (MIRM) was proposed as a distinct clinical entity, separate from erythema multiforme (EM) and Stevens–Johnson syndrome (SJS)/ toxic epidermal necrolysis (TEN). We present a case that illustrates the challenges in classifying these disorders. A 19-year-old girl, with no relevant medical history or recent drug intake, presented with a 3-day history of odynophagia and conjunctivitis, followed by dysuria, dysphagia, and a pruritic febrile rash. Physical examination revealed confluent typical and atypical raised target lesions with a central blister over the face,

The aim of this study was to identify the causes of anaphylaxis in children and adolescents in Portugal, thus contributing to a better knowledge of its etiology, clinical manifestations, and management.MethodsDuring a 10‐year period, a nationwide notification system for anaphylaxis was implemented, with voluntary reporting by allergists. Data on 533 patients under 18 years of age with anaphylaxis were included.ResultsMean age was 8.5 ± 4.9 years, 61% were male; 45% had asthma. Mean age at the first anaphylaxis episode was 5.3 ± 4.7 years (ranging from 1 month to 17 years of age), 63% at pre‐school age. Most reactions occurred at home (57%). Food‐induced anaphylaxis was the leading cause (77%). The main culprit foods were cow's milk (32%), tree nuts (16%), shellfish (13%), egg (12%), fresh fruits (11%), fish (8%), and peanut (8%). Other causes incl...

However, evidence of its effects in elite swimmers is lacking. Therefore, we aimed to assess the effect of 12-week IMT on swimming performance, inspiratory muscle strength, lung function, and perceived breathlessness in elite swimmers. Methods: Elite swimmers from the main FC Porto swimming team (in competitive training for a minimum period of 3 years) were invited to participate and were randomly allocated into intervention or control groups. The intervention group performed 30 inspiratory efforts, twice a day, 5 times a week, against a pressure threshold load equivalent to 50% of maximal inspiratory pressure, whereas the control group performed inspiratory efforts at the same frequency but against a 15% load. Swimming performance was assessed through time trials, converted into points according to International Swimming Federation Points T...

In routine clinical practice, physicians often face complex cases of CSU and need to decide whether patients are suitable for omalizumab treatment and how to manage this therapy. Here, we provide evidence and experience-based answers to the most common and important questions on omalizumab treatment of CSU. At 4 large urticaria centers, questions on the use of omalizumab in the treatment of patients with CSU were collected and then ranked by frequency and importance and grouped into top 5 domains using an interactive consensus approach. We suggest that omalizumab can be used to treat patients with CSU with any of the 3 CSU phenotypes (wheals only, angioedema only, wheals and angioedema), with comorbid chronic inducible urticaria, with cancer, who receive other biologics or cyclosporine, or who are pregnant or want to become pregnant, or are breast-feeding. Omalizumab treatment should be started with 300 mg every 4 weeks, monitored with validated patient-reported outcome measures, and maintained, in responders, until remission of CSU. Finally, partial responders or non responders can benefit from omalizumab updosing or adding or switching to cyclosporine. We believe our suggestions on the use of omalizumab in CSU will help to inform clinical decision making. Follow-up efforts should increase, systematically review, and profile the data available and provide evidence-based recommendations on how to best use omalizumab in CSU.
