A 56-year-old woman presented with a 3-month history of erythematous plaques covered by scales and limited to the right side of her body. The plaques were arranged along Blaschko’s lines with a marked mid-line cutoff. The histopathologic analysis of a skin biopsy in conjunction with the anamnesis allowed the diagnosis of linear psoriasis. Our patient showed a good clinical response to antipsoriatic treatment.

Patients with COVID-19 can require radiological examination, with chest CT being more frequent than neuro-imaging. The objective is to identify epidemiological, clinical and radiological factors considered as predictors of neurological involvement in patients with COVID-19 assessed by neuroimaging and to describe the neuroimaging findings. This retrospective study was performed with 232 consecutive confirmed COVID-19 patients, from two radiological units, which were divided into two groups: (1) those who underwent a brain CT/MRI scan (n = 35) versus (2) those who did not undergo the brain CT/MRI scan, but underwent only chest CT (n = 197). There was a statistically significant difference with associations regarding the COVID-19 brain scan group for: admission to ICU, greater severity of lung injuries, the use of a mechanical ventilator and sepsis. Statistical tendency was found for chronic renal failure and systemic arterial hypertension. Forty-percent of COVID-19 patients from the brain scan group were abnormal on brain CT and/or brain MRI (22.9% of the cases with bleeding or microbleeding, 8.6% with restricted diffusion lesions). One ischemic stroke case was associated with irregularity at the M1 segment of the right middle cerebral artery. There was a case of left facial nerve palsy with enhancement of the left geniculate ganglia. An analysis of the olfactory bulbs was possible in 12 brain MRIs and 100% had enhancement and/or microbleeding. In conclusion, a more severe COVID-19 disease from ICU, a more severe form of lung disease, the use of mechanical ventilator and sepsis were associated to the COVID-19 patients with neurological involvement who had undergone brain scans. Microvascular phenomenon was a frequent finding in the brain and olfactory bulbs evaluated by neuroimaging.

BackgroundChronic urticaria is defined as the appearance of urticarial lesions and/or angioedema during a period of more than six weeks. We aimed at developing the Portuguese version of the Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL) and at testing its reliability and the content, construct and criterion validity.MethodsThe forward-backward approach to a linguistic equivalence was followed, after which a clinical review and a cognitive debriefing with patients were performed. The intraclass correlation coefficient checked test-retest reliability with patients filling the same questionnaire with one week apart and the Cronbach’s alpha indicator assessed the internal consistency. Construct validity was tested by an exploratory factor analysis and by hypothesis tests involving sociodemographic and clinical patient characteristics, including the urticaria control test (UCT). On the other hand, criterion validity was tested through correlations with the Short-Form Health Survey SF-36, EQ-5D-5 L, and the Dermatology Quality of Life Index (DLQI).ResultsA total of 162 patients from seven hospital units were included. The mean (standard deviation) age was 42.6 (13.3) and 81.6% were female. CU-Q2oL was entirely filled by all respondents. Internal consistency was 0.947 for the overall score, ranging from 0.661 (limits) to 0.899 (sleep problems) and the corresponding reproducibility indicator was 0.910, based on 23 patients and ranging from 0.711 (swelling) and 0.957 (looks). Exploratory factor analysis in general confirmed the original structure originally obtained by the authors. All CU-Q2oL dimensions were highly correlated with DLQI Index and differentiated well between males and females, and between different levels of wheals and pruritus. In addition, moderate negative correlations were found between Cu-Q2oL scores and the dimensions from SF-36 and EQ-5D-5 L.ConclusionsThe satisfactory metric properties confirmed the cultural adaptation and validity of CU-Q2oL into Portuguese population, providing the clinicians with a valid tool to evaluate the impact of chronic urticaria on patient’s QoL and therefore adjust their treatment.Trial registration numberNot applicable.

The case study is a widely used method in qualitative research. Although defining the case study can be simple, it is complex to develop its strategy. Furthermore, it is still often not considered to be a sufficiently robust research strategy in the education field because it does not offer well-defined and use well-structured protocols. One of the most frequent criticisms associated with the case study approach is its low validity and reliability. In this sense, this study aims to concisely explore the main difficulties inherent to the process of developing a case study, also attempting to suggest some practices that can increase its reliability, construct validity, internal and external validity.

Papulonecrotic tuberculid is a rare, chronic, recurrent and symmetric eruption of necrotizing skin papules arising in crops, involving primarily the limbs. It occurs in less than 5% of active tuberculosis. Typically bacilli are not detected in any of the cutaneous lesions. Extracutaneous tuberculosis primary focus is only detected in 30–40% of the cases, being the lymph nodes the most common location. Antituberculosis treatment is rapidly effective and is often the main confirmation of the diagnosis.

Background The COVID-19 pandemic introduced new challenges in several dimensions in healthcare services. Herein, we describe the real-life strategies and therapeutic options adopted by dermatologists regarding their patients with psoriasis being treated with or with an indication for systemic therapy during the first COVID-19 lockdown period in Portugal. Methods The study involves a web-based survey on the clinical management of systemic therapy for psoriasis during the COVID-19 pandemic administered to Portuguese dermatologists. The survey consisted of 55 questions (4 open-ended questions; 51 closed-ended questions), grouped into 6 sections. Results A total of 60 dermatologists voluntarily participated in this survey. Nearly 63% of the participants opted for suspending biologics during the COVID-19 lockdown period and 23.3% increased the time between drug administrations. Eighty percent of the participants agreed that biologics did not change the probability of acquiring COVID-19 and 58.4% believed that these drugs decreased or did not change the severity of the disease. Approximately one-third of the participants opted not to prescribe a biological agent in patients despite clinical indication over the duration of the pandemic. Nearly 25% of the participants opted for suspending traditional immunosuppressant administration. Virtual appointments were an option for 93.3% of the participants. Conclusion The COVID-19 pandemic has significantly affected the management of patients with psoriasis being treated with or with an indication for systemic therapy. Some of the decisions made during the first lockdown period were contrary to what we know today. These decisions might have had a significant impact on patients’ quality of life and on future therapeutic success. An adequate interpretation and analysis of the available data will be extremely important to an insightful adaptation of the clinical practice in future confinement or restrictive scenarios.

O cancro cutâneo não-melanoma (CCNM), designação conjunta para os carcinomas basocelulares (CBC) e espinhocelulares (CEC), é o tipo de neoplasia cutânea maligna mais frequente. Com vista à caracterização epidemiológica deste grupo de tumores, foi realizada uma análise retrospectiva dos doentes portadores de CCNM identificados por análise histológica de todas as biopsias cutâneas incisionais ou excisionais ao longo de 5 anos (2004-2008) num serviço de Dermatologia. Foram identificados 3075 CCNM, representando 88% do total de neo- plasias malignas diagnosticadas no mesmo período (n=3493). Destes, 68,3% eram CBC. No seu conjunto, a popu- lação de CCNM era predominantemente constituída por indivíduos idosos e do sexo feminino, tendo sido observado um aumento consistente de frequência ao longo do período avaliado (5,25%/ano). A maioria dos CCNM (n=1443, 81,7%) foi identificada nas áreas de pele foto-exposta, representando 95,1% de todas as neoplasias malignas em áreas foto-expostas. O CCNM foi a neoplasia mais representativa na generalidade das áreas topográficas, à excep- ção do abdómen e da pélvis, representando, em particular, mais de 95% das neoplasias malignas da face, da região cervical e do couro cabeludo. O CBC foi o CCNM predominante em todas as localizações, à excepção dos membros inferiores e superiores, lábio inferior e da área genital, onde o CEC representou, respectivamente, 77,7%, 77,4%, 94,7% e 95,3% dos casos. O CCNM, como neoplasia maligna cutânea mais frequente, deverá ser alvo de uma monitorização regular, com vista à determinação da sua dinâmica epidemiológica, da eficácia das medidas preventivas e adequação dos recursos de saúde.PALAVRAS-CHAVE – Neoplasias da Pele; Carcinoma Basocelular, Carcinoma Espinhocelular.

ObjectiveTo verify the impact and findings of the COVID-19 patients’ group that underwent brain scans in comparison to the group which only chest CT was performed.Method876 suspected COVID-19 patients and a subsample of 232 cases with confirmed COVID-19 who underwent brain CT/MRI scan (n=35) or only chest CT (n=197) in two radiology departments, were evaluated.Results5.59% of all suspected COVID-19 patients found had brain scans and 98.74% chest CT. There was a statistically significant difference with associations regarding the COVID-19 brain scan group for: admission to ICU, greater severity of lung injuries, the use of mechanical ventilator, seizure, sepsis, and stroke and statistical tendency for chronic renal failure and systemic arterial hypertension. 40.0% of COVID-19 patients from the brain scan group were abnormal on brain CT and/or brain MRI. 22.9% cases with any kind of bleeding or microbleeding, 8.6% with restricted diffusion lesions. One ischemic stroke case was associated with irregularity at M1 segment of the right middle cerebral artery. There was a case of left facial nerve palsy with enhancement of left geniculate ganglia. An analyse of the olfactory bulbs was possible in 12 brain MRIs and 100% had enhancement and/or microbleeding. There was no statistical difference regarding death (9.1% versus 5.2%).In conclusionthe COVID-19 patients group on which brain CT and/or MRI needed to be performed was statically associated with the more severe COVID-19 disease, an indication to ICU, a more severe form of lung disease, use of mechanical ventilator, seizure, sepsis and stroke. Less than half of patients had abnormal brain imaging scans with all of them showing vascular brain injury lesion, being more frequently microbleeding or bleeding, followed by restricted diffusion lesions. All the olfactory bulbs evaluated showed injury by vascular phenomenon, probably methahemoglobine by microbleeding or microthrombus and/or abnormal enhancement
