Case Reports
Lesson of the month 1: Pericardial mass and cardiac tamponade associated with Mycoplasma pneumoniae.
Mycoplasma pneumoniae primarily causes respiratory tract infections. Extrapulmonary manifestations are seen in 20-25% of cases. Cardiac involvement is rarely reported. ⋯ This required emergency pericardial fenestration. The patient improved dramatically postoperatively on antibiotics and there was no recurrence of the pericardial effusion on follow up. This case highlights the often forgotten invasive properties of a common respiratory tract pathogen and emphasises the need to consider this easily treatable entity in the differential diagnosis of idiopathic pericardial effusions.

Case Reports
Lesson of the month 2: Severe reactivation of hepatitis B after immunosuppressive chemotherapy.
Patients with current or past hepatitis B virus (HBV) infection are at risk of viral reactivation if they receive immune-modulating treatment or chemotherapy. This can range from subclinical elevation in HBV DNA levels, to abnormal liver function tests, to severe hepatitis with liver failure and risk of death. ⋯ Patients with positive hepatitis B serology should be referred for specialist advice. Prophylactic antiviral treatment is recommended for patients with current/past hepatitis B who receive immunosuppressive chemotherapy.
