- Biochemical and Anthropometric Outcomes in Paediatric Patients with Heterozygous Familial Hypercholesterolemia after COVID-19 Pandemic Lockdowns: An Exploratory AnalysisPublication . Peres, M; Moreira-Rosário, A; Padeira, G; Gaspar Silva, P; Correia, C; Nunes, A; Garcia, E; Faria, A; Teixeira, D; Calhau, C; Pereira-da-Silva, L; Ferreira, AC; César Rocha, JThe COVID-19 pandemic lockdowns affected the lifestyles of children and adolescents, leading to an increase in childhood obesity. Paediatric patients with familial hypercholesterolemia (FH) may be more susceptible to lockdown effects due to their increased cardiovascular risk. However, data are lacking. We investigated the effect of lockdowns on the metabolic profile of paediatric patients with FH. Blood lipids and anthropometry measured in September 2021-April 2022 were retrospectively compared with pre-pandemic values. Thirty participants were included (1-16 years; 57% female). From baseline to post-pandemic, median [P25, P75] blood LDL-C concentration was 125 [112, 150] mg/dL vs. 125 [100, 147] mg/dL (p = 0.894); HDL-C was 58 [52, 65] mg/dL vs. 56 [51, 61] mg/dL (p = 0.107); triglycerides were 64 [44, 86] mg/dL vs. 59 [42, 86] mg/dL (p = 0.178). The BMI z-score did not change significantly (0.19 [-0.58, 0.89] vs. 0.30 [-0.48, 1.10], p = 0.524). The lack of deterioration in metabolic profiles during lockdowns is positive, as some deterioration was expected. We speculate that patients and caregivers were successfully educated about healthy lifestyle and dietary habits. Our results should be interpreted with caution since the study sample was small and heterogeneous. Multicentre research is needed to better understand the impact of lockdowns on this population.
- Case Report: Fourth Branchial Cleft Cyst: A Case of Acute Suppurative ThyroiditisPublication . Caseiro Alves, ME; Nunes, A; Galhardo, JThis case report presents a 4 year-old-female patient with a neck mass who was diagnosed with an infected fourth branchial cleft cyst with left thyroid lobe involvement through fistulation. The case emphasizes the importance of considering uncommon etiologies, such as congenital anomalies, as a differential diagnosis when evaluating pediatric neck masses. The patient was prescribed broad-spectrum antibiotics, which led to the regression of the mass and inflammatory signs. Close follow-up in endocrinology and otorhinolaryngology appointments was maintained, and after 7 months, hypoplasia of the left lobe was observed. Thyroid function was reevaluated, and after two years, no recurrences were noted. The case highlights the significance of a comprehensive examination and assessment of corresponding clinical features, which can significantly reduce the rate of misdiagnoses and achieve an individualized diagnosis.
- COVID-19 in a Pediatric Cohort—Retrospective Review of Chest Computer Tomography FindingsPublication . Pina Prata, R; Forjaco, A; Ruano, C; Lopes Dias, J; Fernandes, L; Ferreira, A; Alves, P; Cabrita Carneiro, R; Nunes, A; Soares, EBackground: Radiological features of the novel 2019 coronavirus disease (COVID-19) have been mainly described in adults. Available literature states that imaging findings in children are similar but less pronounced. The aim of this study is to describe and illustrate the chest computer tomography (CT) features of pediatric COVID-19. Results: This retrospective study was based on the review of all the chest CTs performed in pediatric patients with confirmed COVID-19 disease between March 8th and May 26th 2020 (n = 24). The presence of comorbidities and coinfection was assessed, as well as timing of CT examination in relation to the onset of symptoms. CT findings were categorized as typical, indeterminate, atypical, and negative for COVID-19 according to International Expert Consensus Statement on Chest Imaging in Pediatric COVID-19 Patient Management. This study found that CT findings were abnormal in 17 (71%) patients, with 5 (21%), 9 (38%), and 3 (13%) patients considered to have typical, indeterminate, and atypical findings, respectively. The most common CT patterns were multiple ground-glass opacities (58%), followed by consolidations (50%). Six patients showed predominantly peripheral distribution of parenchymal abnormalities. A halo sign was identified in 3 patients and a perilobular pattern was identified in one of the cases with typical findings. Conclusions: Chest CT findings in children infected with SARS-CoV-2 can be subtle or absent. Besides recognizing typical findings, radiologists should be able to identify features that favor different or concomitant diagnosis.
- Intestinal Hemangiomatosis: Case Report of an Uncommon Cause of Rectal BleedingPublication . Pina-Prata, R; Ruano, CA; Carvalho, VB; Nunes, A; Soares, EA four-month-old girl presented with recurrent low gastrointestinal hemorrhage. Abdominal ultrasound showed diffuse parietal thickening and hyperemia of the colon. Computed tomography (CT) demonstrated diffuse thickening of the colon but also intense arterial globular mural enhancement with diffuse filling in the portal phase. Colonoscopy revealed multiple pseudopolipoid lesions along the colon which were histologically diagnosed as hemangiomas. The infant was diagnosed with gastrointestinal hemangiomatosis and was treated with propranolol resulting in complete resolution of symptoms.

- Lesões do Sistema Nervoso Central na Síndroma de Adams-OliverPublication . Gomes, L; Castro, J; Matos, M; Nunes, A; Furtado, J; Barrueco, MCReportam-se dois casos de doentes do sexo feminino com dois anos de idade e síndrome Adams-Oliver, que se caracteriza por um defeito congénito do escalpe e alterações malformativas congénitas dos membros, a que se associaram malformações e complicações do SNC. O diagnóstico foi feito à nascença e a aplasia cútis congénita caracterizava-se não só por extenso defeito no escalpe, mas também no osso subjacente, com exposição dos seios durais. A variabilidade das duas situações clinicas, traduziu-se essencialmente pela exetnsão e gravidade das lesões osteocutâneas dos membros e do crânio, pelas anomalias do SNC e pelo tipo de intercorrências. Numa criança detectou-se por TC e RM hemimegalencefalia focal do hemisfério direito e a outra apresentou durante o decuros da doença lesões encefaloclásticas e herniação encefálica, que necessitou de correcção cirúrgica. Ambas sobreviveram, mas o diagnóstico de lesão malformativa do SNC e a ocorrência de lesões encefaloclásticas modificaram de forma determinante o prognóstico inicial.
- Manifestações Sistémicas de um Tumor CardíacoPublication . Nunes, A; Gomes, VOs autores apresentam um caso clínico de mixoma cardíaco que se manifestou por dois episódios de acidentes vasculares cerebrais (AVC) e mimetizou um processo de vasculite. Tecem considerações sobre a complexidade e gravidade desta patologia, o seu diagnóstico diferencial, terapêutica e prognóstico.
- OHVIRA Syndrome with a Blind-Ended Ureteral RemnantPublication . Sousa, R; Amante, S; Carneiro, R; Nunes, A; Soares, EOHVIRA syndrome is characterized by a didelphys uterus with an obstructed/blind hemi-vagina and ipsilateral renal agenesis. We presented a case of a female child with a pre-natal diagnosis of left renal agenesis whose post-natal imaging findings were consistent with OHVIRA syndrome.
- Perfil Hipertensivo dos Doentes com Doença Vascular CerebralPublication . Nunes, A; Dias, L; Ribeiro, J; Gomes, V; Baptista, AA HTA é uma das situações de risco mais referenciada para o ocorrência de doença vascular cerebral. Estão documentados antecedentes de HTA em 25 a 40% dos doentes que sofreram AVC. Outros estudos apontam para uma frequência de 80% de HTA na altura do acidente. Por isso, é importante o conhecimento da história evolutiva da HTA, bem como a sua repercursão num doente com AVC. Os autores apresentam um estudo prospectivo de 470 doentes que sofreram um primeiro AVC ou AIT. Pretendem analisar o perfil hipertensivo desses doentes, relacioná-lo com o tipo de doença vascular cerebral, e caracterizar a evolução da HTA 6 meses após o acidente. Após a análise estatística dos resultados obtidos concluíram: - na população estudada a prevalência de HTA foi de 67,2%; - 68% dos doentes com antecedentes de HTA não tinham a HTA controlada na altura do acidente; - a duração média de HTA conhecida antes do AVC ou AIT foi de 104 meses; - a HTA foi de início mais precoce e de estádio mais grave nos doentes com AVC hemorrágico, comparativamente com os doentes que sofreram doença vascular isquémica; - seis meses após AVC/AIT, 65% dos doentes não tinham a HTA controlada.
