Metal Fume Fever: An Underdiagnosis.

Metal fume fever (MFF) is an auto-limited acute febrile respiratory syndrome that may mimic an acute viral respiratory disease after exposure to the fumes of metal oxides. Due to the similar presentation of an influenza-like illness, it remains an underdiagnosed disease. It is typically a benign and self-limited entity that resolves over 12-48 hours following cessation of exposure, but symptoms may reoccur with repeated exposure.

Morvan's Syndrome: The Importance of Knowing Different Risk-Associated Phenotypes and Antibodies in Identifying the Correct Underlying Tumor.

Paraneoplastic neurologic syndromes (PNS) are neurologic disorders that can affect any part of the nervous system, occur in association with cancer, and have an immune-mediated mechanism that produces direct damage to the neural tissue. Neurological symptoms frequently precede, in months to years, the symptoms directly attributed to the primary tumor, requiring a high clinical suspicion for adequate investigation. We report the case of a man in his early 80s admitted for an altered level of consciousness, alternating between periods with stupor and drowsiness, short-term waking states and psychomotor agitation, respiratory failure and dysautonomia, resembling a Morvan's syndrome.

Severe Pneumonia Caused by SARS-CoV-2: A Novel Cause of Platypnoea-Orthodeoxia Syndrome.

Unlabelled: Platypnoea-orthodeoxia syndrome (POS) is a condition characterized by dyspnoea and hypoxaemia while sitting or standing, which improves during decubitus. It is usually caused by intracardiac right-to-left shunting through a patent foramen ovale but may also occur due to pulmonary ventilation-perfusion mismatch of other aetiologies. A new cause of POS was recently described: SARS-CoV-2 pneumonia.
