Cerebral venous air embolism (CVAE) is an extremely rare phenomenon. Most reports of cerebral air embolism focus on the arterial territory, and consequently CVAE has remained poorly understood, especially regarding its pathophysiology and treatment. The authors describe an elderly male patient who was admitted through the Emergency Department with subacute confusion. ⋯ No potential causes were found apart from previous peripheral vein cannulation and intravenous medication administration. The patient received supportive treatment, with complete radiological resolution of the gas emboli, while maintaining his previous confusional state. The aim of this report is to highlight a rare and understudied entity, and discuss its causes, proposed pathophysiology and appropriate management.

Boerhaave syndrome is rare, has an non-specific clinical presentation and most commonly develops after persistent vomiting. Septic shock dominates the clinical picture as a result of extensive infection of the mediastinum and pleural and abdominal cavities. The current management of Boerhaave syndrome includes conservative, endoscopic and surgical treatments. ⋯ The hospital stay was complicated by pleural effusion infection requiring broad-spectrum antibiotics and prosthesis substitution. The patient was discharged after 60 days of hospitalization, without the need for oxygen supplementation, and scoring 80% on the Karnofsky Performance Status Scale. The increase in average life expectancy requires a case-by-case approach, where the benefits of invasive manoeuvres and likelihood of discharge are weighed against an acceptable quality of life, aiming to prevent futile medical treatment.

Metabolic acidosis is a common clinical disturbance due to increased plasma acidity caused by a primary decrease in serum HCO3- concentration. It is classified as normal or high anion gap metabolic acidosis. High anion gap metabolic acidosis can result from either a decrease in unmeasured cations (K+, Ca2+, Mg2+) or an increase in unmeasured anions (PO4 3-, albumin). ⋯ High anion gap metabolic acidosis is diagnosed in children with inherited defects in enzymes of the γ-glutamyl cycle. In adults, this disorder from pyroglutamic acid has been described in association with chronic acetaminophen misuse. We report a case of pyroglutamic acidosis in a woman with acute misuse of acetaminophen concurrent with chronic use.

Delayed Diagnosis of Atypical Presentation of Myasthenia Gravis.
Myasthenia gravis is an autoimmune disorder affecting the neuromuscular junction, resulting in muscle fatiguability and weakness. The pathological characteristics of the disorder include ocular weakness resulting in diplopia and/or ptosis. More generally, the disease can result in fluctuant weakness of skeletal muscle, predominantly affecting ocular, bulbar and respiratory muscles. ⋯ We present a case of an 83-year-old male who presented with a 1 year history of dysphagia for solids and fatigable dysarthria. Following a diagnosis of myasthenia gravis, he was initiated on corticosteroid treatment. He later descended into myasthenic crisis, requiring invasive ventilation measures due to a failure of both non-invasive ventilation and intravenous immunoglobulin G (IVIG) to achieve therapeutic goals.

A Low Rivaroxaban Plasma Level May Indicate Anticoagulation Undertreatment.
Few reports have been published on the correlation between plasma concentrations of rivaroxaban and clinical outcome in patients who have experienced venous thromboembolism. This article describes the case of a 44-year-old woman who experienced deep vein thrombosis during anticoagulation therapy with rivaroxaban, with evidence of repeated low plasma levels of the drug. We postulate that the determination of plasma rivaroxaban anti-Xa activity can be useful in the evaluation of anticoagulation therapy in selected cases.
