The diagnosis of constrictive pericarditis requires a high degree of clinical suspicion, for the signs and symptoms of this disease can be falsely attributed to other causes. Herein, we present a case of a 70-year old retired farmer whose symptoms of right heart failure were initially attributed to co-existing pneumonia and pulmonary embolism. He was discharged. Three weeks later he presented with worsening breathlessness and ascites. Echocardiography, computed tomography and cardiac catheterization revealed the diagnosis of constrictive pericarditis. He underwent complete pericardectomy and to date has made a good recovery. This case exemplifies the difficulty in diagnosing this condition, the investigation required, and provides a discussion of the benefit and outcomes of prompt treatment.

SummaryWe present a rare, but increasingly recognised, cause of thrombocytopenia in a 69-year-old Caucasian female. Complete haematological investigation, including blood films and autoantibody screen, did not reveal a cause for her thrombocytopenia. Omission of potentially offending medication did not improve the low platelet count. She had no features of systemic infection or inflammatory disease on history and examination. In light of persistent thrombocytopenia, Helicobacter pylori stool antigen was tested, and found to be positive. Platelet count improved after eradication therapy for H pylori. This prevented the need for steroid and immunoglobulin treatment in this patient. BACKGROUND

Pregnant patients commonly present to the acute medical team with symptoms requiring further investigation. Palpitations are a common reason for presentation on the acute medical take, and most acute physicians will be familiar with the process of investigation. The combination of pregnancy and palpitations raises a broad differential diagnosis and can complicate the management pathway. This problem based review is designed to summarise the key issues which may arise during the management of a typical patient presenting in this way.
