A 47-year-old woman presented to the emergency department with sudden-onset dull nonradiating chest pain and palpitations. She denied other symptoms such as shortness of breath, dizziness, or diaphoresis. Her medical history was significant for generalized anxiety disorder, obesity, and former tobacco use (less than 1 pack per day for 5 years, quit more than 20 years ago).

We report a young man with a mixed non-seminomatous germ cell tumour who presented with pulmonary embolism and a large tumour thrombus extending from the inferior vena cava to the right atrium and pulmonary veins. Due to haemodynamic instability, he received therapeutic anticoagulation and an abridged 'cycle 0' chemotherapy regimen, followed by standard bleomycin, etoposide and cisplatin and delayed orchiectomy.

Frequently associated with atrial septal defects, PAPVR may present with non-specific symptoms such as exertional dyspnoea and is often misdiagnosed as pulmonary hypertension of other origins. We describe a woman with progressive exertional dyspnoea and lower extremity oedema in the setting of newly identified precapillary pulmonary hypertension.

Bevacizumab is commonly used to treat this complication, but response is often partial and may diminish over time. We present a patient with ACVRL1-related HHT and high cardiac output who failed pazopanib and developed apparent bevacizumab resistance with symptom recurrence despite maintenance and reintroduced therapy.

Homozygous variants in HHT-related genes are exceptionally rare and have not been reported in -related HHT to date. We report the first known instance of a novel homozygous missense variant in the gene (c.

Iron deficiency due to chronic bleeding events is a common manifestation that produces a range of nonspecific symptoms. We report on a patient with HHT with longstanding fatigue and exercise intolerance, which was persistently attributed to iron deficiency, who was revealed to have glycogen storage disease type V, an autosomal recessive metabolic myopathy caused by deficiency of myophosphorylase due to variants.

The syndrome is most likely to occur in minor ABO blood group mismatched or Rh incompatible transplantation. Although generally mild and self-limited, the resulting haemolytic burden has the potential to increase the risk of infection, graft failure and death.

There is a growing awareness of the diverse phenotypic presentation of arrhythmogenic cardiomyopathy, which may demonstrate preferential involvement of the left, right or both ventricles. A subset of arrhythmogenic cardiomyopathy may be due to mutations of desmosomes, intercellular junctions of the myocardium that promote structural and electrical integrity.

The entity is a clinical diagnosis. Evaluation consists of recognizing systemic lupus erythematosus-like features, identifying an appropriate causative agent, observing elevations of characteristic autoantibodies, and obtaining positive response with drug discontinuation.

Curative treatment entails allogeneic hematopoietic stem cell transplant, which is often not a feasible option due to older age and significant comorbidities. Immunotherapy has the cytotoxic capacity to elicit tumor-specific killing with long-term immunological memory.

Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant hereditary disorder characterized by recurrent spontaneous epistaxis, mucocutaneous telangiectasias, and solid organ arteriovenous malformations (AVMs). Pulmonary hypertension (PH) is an increasingly recognized complication in patients with HHT, most often precipitated by high-output heart failure in the presence of hepatic AVMs as well as pulmonary arterial hypertension in the form of a proliferative vasculopathy. The presence of PH in patients with HHT is associated with significant elevations in rates of morbidity and mortality.

There is a paucity of prognostic indicators for tumor burden or potential for embolic cerebrovascular events (CVEs). This study was performed to address these gaps.

Primary capillary leak syndrome is a rare, episodic medical illness of unknown molecular pathology while secondary capillary leak syndrome may be precipitated by any number of inflammatory and infectious syndromes. Decompression sickness, a disorder of depressurisation, has been identified as a very rare trigger.

Contemporary interest in the underlying inflammatory paradigm of SCD has emphasized the role of the neutrophil-lymphocyte ratio (NLR) as a prognostic inflammatory marker.
Methods: We retrospectively reviewed 268 hospitalized patients with SCDs of different genotypes (HbSS, HbSβ thalassemia, HbSβ thalassemia, and HbSC), totaling 3329 hospital admissions over a 10-year period.
