Modelling Physical Fatigue Through Physiological Monitoring Within High-Risk Pr...

Physical fatigue is not only a tiredness condition but can also be a symptom of various diseases or a precursor of workplace accidents and incidents. High-risk professions like firefighters and military personnel are more frequently exposed to it and its consequences. To contribute to current research efforts towards physical fatigue quantification approaches for these professionals, the current work aimed to t...

CYP21A2 Gene Pathogenic Variants: A Multicenter Study on Genotype-Phenotype Cor...

BACKGROUND: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is an autosomal recessive disorder characterized by 3 overlapping phenotypes: salt-wasting (SW), simple virilizing (SV), and non-classic (NC). We aimed at conducting a nationwide genotype description of the CAH pediatric patients and to establish their genotype-phenotype correlation. METHODS: CAH patients were recruited fr...

Abernethy malformation: beware in cases of unexplained hepatic encephalopathy i...

The Abernethy malformation consists of a congenital extrahepatic portosystemic shunt and is believed to be extremely rare in humans. The potential implications of abnormal portovenous shunting and decreased hepatic portal flow are numerous and potentially serious. Although congenital extrahepatic portosystemic shunts are increasingly suspected and diagnosed in specialized centres, much of their clinical present...

Autoimmune alternating hyper- and hypo-thyroidism: a rare condition in pediatrics

Alternating between hyper- and hypo-thyroidism may be explained by the simultaneous presence of both types of TSH receptor autoantibodies (TRAbs) - thyroid stimulating autoantibodies (TSAbs) and TSH blocking autoantibodies (TBAbs). It is a very rare condition, particulary in the pediatric age. The clinical state of these patients is determined by the balance between TSAbs and TBAbs and can change over time. Man...

NOD2 gene mutations in ulcerative colitis: useless or misunderstood?

PURPOSE: NOD2 mutations have been linked to an increased risk of Crohn's disease and to some of its phenotypes. The association between NOD2 mutations and susceptibility to ulcerative colitis (UC) remains somewhat controversial and potential correlations between these mutations and UC phenotype have not been studied. AIM: To assess whether NOD2 mutations are a risk factor for UC in Portugal and if there are any...

In vitro isolation and seroprevalence of Toxoplasma gondii in stray cats and pi...

Oral contamination with Toxoplasma gondii oocysts shed by cats into the environment has been linked to severe outbreaks of human toxoplasmosis. Pigeons (Columba livia) are highly susceptible to oral infection with oocysts and indirectly indicate soil contamination, since they feed from the ground. A seroprevalence study was performed on cats and pigeons captured in the city of Lisbon. Serum samples collected fr...

A modified agglutination test for the diagnosis of Besnoitia besnoiti infection

Abstract Bovine besnoitiosis is caused by Besnoitia besnoiti, an obligate intracellular apicomplexan parasite. Affected animals present cutaneous and systemic manifestations and the disease may lead to considerable economic losses. Although generally associated to tropical and subtropical areas, bovine besnoitiosis is now considered an emergent disease in Europe, due to the increasing number of new cases and ap...

Hiperplasia congénita da supra-renal: quando o mesmo genótipo tem diferentes fe...

Cutaneous pseudallescheria boydii infection in a renal transplant patient: A ca...

We describe the case of a 59-year-old male renal transplant recipient who presented with a 1 month history of nodular, erythematous, and crusted lesions on the anterior surface of the left leg. There was no history of trauma. The patient had no systemic signs or symptoms. A skin biopsy revealed evidence of a deep fungal infection, with septate and branching hyphae amongst the dermal inflammatory infiltrate, but...

Livedoid vasculopathy and hypercoagulability in a patient with primary Sjögren'...

BACKGROUND: A 31-year-old woman presented with a 5-year history of painful ulcerations, palpable purpura, porcelain-white atrophic scars of the malleolar region and dorsal aspect of the feet, livedo reticularis on the limbs, arthralgia, xerophthalmia, and xerostomia. METHODS: Skin biopsy revealed vessel wall hyalinization and thrombosis of the microvasculature with a very scarce dermal inflammatory infiltrate. ...
