Incidental abdominal aortic aneurysms are largely undocumented and unmonitored.

Background: In countries without organized population screening, incidental detection remains the major form of abdominal aortic aneurysm (AAA) diagnosis. Despite the presumed homogeneity in AAA prevalence, its rate of repair is highly variable, with Portugal treating 2 to 6 times fewer AAA per habitant than other western countries.

Objectives: To evaluate the detection rate and monitoring of incidental AAA in a multicentre cohort from Portuguese hospitals.

Not All Pulmonary Densifications Are COVID-19: A Case Report About Lemierre's Syndrome.

Lemierre's syndrome is a rare and a life-threatening disease characterized by anaerobic bacteraemia associated with thrombosis of the internal jugular vein. Odynophagia, otalgia, odontalgia, dyspnoea, cough and fever are the most frequent manifestations. We describe a case of a 37-year-old woman who was admitted to the emergency room due to fever, odynophagia, dyspnoea, myalgia, and pleuritic chest pain.

Dieulafoy's lesion in the cecum: A rare case report presentation.

Introduction And Importance: Dieulafoy's lesion is a rare entity, normally present in the stomach and more rarely in the colon, and it is responsible for 1% to 5% of acute gastrointestinal bleeding cases. Its true incidence may be underrated, since most cases are asymptomatic and difficult to diagnose despite endoscopic advances. We present a clinical case of acute gastrointestinal bleeding due to Dieulafoy's lesion in the cecum.

Perianal Paget Disease: Different Entities With the Same Name.

Extramammary Paget disease (EMPD) is a rare form of cancer that involves skin areas rich in apocrine glands. The common sites of occurrence include the vulva, perianal region, perineum, and axilla. Perianal Paget disease (PPD) is a subset of EMPD, which arises in the perianal skin.

Portuguese version of Parent-reported Drug Hypersensitivity Quality of Life Questionnaire (P-DrHy-Q): assessment of reliability and validity.

Drug hypersensitivity in children impacts the quality of life of the patients and their caregivers. The parent-reported drug hypersensitivity quality of life questionnaire (P-DrHy-Q), the first disease-specific quality-of-life questionnaire for caregivers who have children with drug hypersensitivity, was recently developed. The aim of this study was to assess the validity and reliability of the portuguese version of the P-DrHy-Q.

Cerebral Venous Thrombosis after BNT162b2 mRNA SARS-CoV-2 vaccine.

The development of SARS-CoV-2 vaccines has raised several concerns regarding venous thromboembolism, namely cerebral venous thrombosis. Although cerebral venous thrombosis has been reported after administration of a viral vector vaccine, due to a possible auto-immune mechanism inducing thrombocytopenia, the same has not happened in mRNA vaccines. We report two cases of cerebral venous thrombosis, shortly after administration of mRNA vaccine.

Hyponatremia in Cancer Patients Hospitalized in a Palliative Care Department: A Cross-Sectional Analysis.

Introduction: Hyponatremia is frequent in cancer patients, as many studies carried out in these patients have shown. However, there are only a few studies carried out at the end of life and in palliative care. The aim of this study was to determine the prevalence of hyponatremia in cancer patients in the palliative care department of an oncology center and its association with survival.

Fourier-Transform Infrared Spectroscopy as a Discriminatory Tool for Myotonic Dystrophy Type 1 Metabolism: A Pilot Study.

Myotonic dystrophy type 1 (DM1) is a hereditary disease characterized by progressive distal muscle weakness and myotonia. Patients with DM1 have abnormal lipid metabolism and a high propensity to develop a metabolic syndrome in comparison to the general population. It follows that metabolome evaluation in these patients is crucial and may contribute to a better characterization and discrimination between DM1 disease phenotypes and severities.

Incarcerated paraoesophageal hernia complicated with distal oesophageal perforation: a combined laparoscopic and endoscopic approach.

Paraoesophageal hernias are common, but symptoms are not always present nor pathognomonic of this condition, and patients may be suffering for many years before a diagnosis is made. Incarceration and strangulation are rare, but they are life-threatening complications, warranting an emergent surgical repair. Hiatal hernia incarceration causing distal oesophagus perforation is even rarer.

Fecal Dipeptidyl Peptidase-4: An Emergent Biomarker in Inflammatory Bowel Disease.

Introduction: Dipeptidyl peptidase-4 (DPP-4) is a membrane-bound glycoprotein that acts as a receptor but also exists in a soluble form. It has been recognized as a mediator of inflammation and considered a biomarker in inflammatory bowel disease (IBD).

Methods: We evaluated a prospectively recruited cohort, consisting of 101 patients with IBD, using validated clinical indexes; 22 patients with ulcerative colitis (UC) underwent endoscopic evaluation.

Esophageal varices: A rare non-cardiac finding in echocardiography.

A 43-years-old patient with hepatitis C and HIV co-infection was referred to debridement of a left sternoclavicular septic arthritis. Due to suspicion of endocarditis, the patient underwent transthoracic echocardiogram which revealed an mass posterior to left atrium and descending aorta. A thoracic computed tomography revealed esophageal varices.

An Atypical Presentation of Diffuse Large B-Cell Lymphoma.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma (NHL) and it can metastasize to extranodal sites. The involvement of the adrenal glands is rare. In this report, we discuss the case of a 65-year-old man with complaints of asthenia, anorexia, hypersudoresis, and a weight loss of 10 kg in the month prior to his presentation.

Myocardial rupture and systemic lupus erythematosus: a case report.

Background: Systemic erythematous lupus (SLE) is an autoimmune disease associated with significant cardiovascular morbidity and mortality, even in young patients.

Case Summary: A young female with recently diagnosed SLE under corticotherapy developed pulmonary oedema and respiratory failure. The diagnostic workup revealed mildly elevated cardiac troponin, significantly elevated NT-proB-type natriuretic peptide (NT-proBNP) and mild pericardial effusion without other echocardiographic abnormalities.

Jejunal intussusceptions due to metastatic malignant melanoma: a case report.

Intussusception is an infrequent cause of mechanical bowel obstruction in adults and surgical resection is warranted in most cases. Small bowel is a common site of recurrence from cutaneous melanoma but early diagnosis is still a challenge. Acute peritonitis, haemorrhage and obstruction are known clinical presentations.

Chylous ascites: Case report of a rare presentation of blunt abdominal trauma.

Introduction: Chylous ascites is the accumulation of a milk-like peritoneal fluid rich in triglycerides, due to the presence of intestinal lymph in the abdominal cavity. The most common causes of chylous acites in adults are abdominal malignancy and cirrhosis. Very few cases of chylous ascites associated to blunt abdominal trauma have been published in the literature.

Miliary Brain Tuberculomas and Meningitis: Tuberculosis Beyond the Lungs.

Unlabelled: Tuberculosis remains one of the most common infectious diseases. Miliary presentation is a rare and possibly lethal form, resulting from massive lymphohaematogenous dissemination of bacilli. The authors describe the case of a 47-year-old immunocompetent woman, diagnosed with miliary tuberculosis, with both lung and central nervous system involvement, who showed total recovery after starting anti-tuberculous drugs.

Allergic sensitization to Storage Dust Mites: a prospective study of patients with respiratory allergy.

To describe the prevalence of allergic sensitization to Storage Dust Mites (SDM), access whether the place of living and occupational exposure were determinants for SDM sensitization and study association between Lepidoglyphus destructor and other SDM sensitization. Prospective analysis of patients evaluated for suspected allergic rhinitis and/or asthma that performed Skin Prick Tests (SPT) to SDM between January and December 2018 in our Department. Two hundred consecutive patients were evaluated for rhinitis and/or asthma in our outpatient consultation: 123 (61.
