A case report suggests a possible link between vaping and aggressive lung cancer, highlighting the need for further research to understand vaping's health risks, especially since the patient had a history of smoking but switched exclusively to e-cigarettes for over a decade before developing fatal lung cancer.
A case report has highlighted the association between cobalamin (vitamin B12) deficiency and psychotic symptoms in a patient with celiac disease. The 75-year-old woman presented with auditory hallucinations, persecutory delusions, thought broadcasting, and insomnia. Laboratory investigations detected mild anemia and cobalamin deficiency, but were unremarkable for other causes of psychosis. After starting olanzapine and cobalamin replacement, she had a good clinical response with full remission of delusions in 5 days. She remained symptom-free at several follow-up assessments with her community mental health team and maintained normal cobalamin levels as monitored by her primary care team.
A case report has been published describing a patient who developed intracranial hemorrhage after receiving the Pfizer-BioNTech COVID-19 vaccine. The patient, who had a history of hypertension and was taking aspirin, presented with a severe headache and was found to have a subarachnoid hemorrhage. While the authors note that this is a rare event and the benefits of vaccination outweigh the risks, they suggest that individuals with a history of bleeding disorders or those taking anticoagulants should be monitored closely after vaccination.
