Malignancy risk of thyroid nodules: quality assessment of the thyroid ultrasoun...

Background Thyroid nodules are a challenge in clinical practice and thyroid ultrasonography is essential for assessing the risk of malignancy. The use of ultrasound-based malignancy risk classification systems has been recommended by several scientific societies but radiologist’s adherence to these guidelines may vary. The authors aimed to analyze the quality of the information provided by the thyroid ultrasoun...

Food Insecurity Levels among University Students: A Cross-Sectional Study

Background: University students may be vulnerable to food insecurity (FI) due to limited financial resources, lower purchasing power, and increasing housing and food costs. This study aimed to assess the prevalence and severity of FI and its associated factors among university students attending a public Portuguese university. Methods: A cross-sectional survey was designed, and data were collected using a self-...

Amiodarone-induced thyrotoxicosis in a pediatric patient: A rare and demanding ...

Thyroid dysfunction is one of the most common adverse effects of amiodarone therapy, ranging from subclinical changes to overt clinical thyrotoxicosis (AIT) and/or hypothyroidism. Due to its heterogeneity, AIT lasts as a defiant entity, leading to a thorny treatment course, particularly in pediatrics. AIT can be classified as either type 1, type 2 or mixed form based on its pathophysiology. Differentiating betw...

Gastric neuroendocrine neoplasm with late liver metastasis

Gastric neuroendocrine neoplasms (GNENs) are classified into three types according to their aetiology. We present a clinical case of a female patient of 66 years and a well-differentiated (grade 2), type 3 GNEN with late liver metastasis (LM). The patient underwent surgical excision of a gastric lesion at 50 years of age, without any type of follow-up. Sixteen years later, she was found to have a neuroendocrine...

Molecular Characterization of a Rare Analphoid Supernumerary Marker Chromosome ...

Analphoid supernumerary marker chromosomes (aSMC) constitute one of the smallest groups of SMC, and are characterized by a centromeric constriction but no detectable alpha-satellite DNA. These marker chromosomes cannot be properly identified by conventional banding techniques alone, and molecular cytogenetic methods are necessary for a detailed characterization. Analphoid SMC derived from chromosome 7 are extre...

Trisomy 15 Mosaicism: Challenges in Prenatal Diagnosis

Pesquisa de Sequências do Cromossoma Y em Indivíduos com Síndroma de Turner

O síndroma de Turner (TS) tem sido descrito em associação com diversas anomalias dos cromossomas sexuais. Embora a maioria dos individuos com TS não apresentem evidência citogenética de sequências do cromossoma Y, diferentes autores consideram que algumas doentes com TS podem possuir uma linha celular minoritária contendo material do cromossoma Y, que não é detectada pela análise citogenética convencional. A id...
