Fulltext The Unusual Cause of Cardiac Tamponade

Othman MK, Yusof Z, Hussin SA, Samsudin N, Muhd Besari AB, W Isa WYH

JACC Case Rep, 2022 Oct 05;4(19):1288-1291.
PMID: 36406916 DOI: 10.1016/j.jaccas.2022.07.016

We present a previously healthy young man with cardiac tamponade. He underwent emergency pericardiocentesis. The pericardial fluid was exudative, and Salmonella sp. was grown on both pericardial and blood cultures. Further investigations revealed that this patient had classical Hodgkin lymphoma, which explains his immunocompromised state predisposing him to this infection. (Level of Difficulty: Advanced.).
Dizzy spells in pregnancy: successful antenatal removal of a huge left atrial myxoma with mitral valve obstruction

Shahbuddin HMA, Hussin SA, W Isa WYH, Mamat AZ, Marzuki A, Yusof Z

Diagnosing atrial myxoma in pregnancy is challenging because patients may present with non-specific symptoms that might be overlooked. The timing of non-obstetric operation usually depends on the nature of the disease, after careful consideration of feto-maternal safety, including the use of cardiopulmonary bypass and placental transfer of anaesthetic drug. A woman in her 30s at 18 weeks of pregnancy presented with recurring dizziness. She underwent successful myxoma excision at 20 weeks under general anaesthesia and cardiopulmonary bypass. The 6×5 cm myxoma was histologically confirmed as myxoma. Early detection of atrial myxoma in pregnancy is crucial, and a clinician has to consider the diagnosis of left atrial myxoma with mitral valve obstruction as a cause of severe dizziness. Optimal outcomes require multidisciplinary management. In this case, surgery during the second trimester of pregnancy enabled a full-term pregnancy with the patient's and foetal well-being and normal postprocedural echocardiography.
Evaluating the Impact of Intensifying Treatment from Human to Analogue Insulin on Glycaemic Control and Insulin Expenditure in Patients with Type 2 Diabetes: A Retrospective Cohort Study

BACKGROUND: Achieving good glycaemic control is essential to reducing the risk of diabetes complications. Insulin is the most effective therapy for achieving good glycaemic control; however, it is associated with a higher risk of hypoglycaemia, especially with human insulin. This study aimed to evaluate the efficacy of intensification from human to analogue insulin and its added cost.
METHODS: This retrospective study was conducted at the Hospital Universiti Sains Malaysia (HUSM). Patients with type 2 diabetes mellitus (T2DM) who underwent intensification for at least 3 months from human to analogue insulin were included in this study. The patients' medical records, haemoglobin A1c (Hba1c) and fasting blood sugar (FBS) were retrieved. The total cost pre- and post-intensification of insulin was obtained from the pharmacy database. Differences in HbA1c, FBS and total insulin cost pre- and post-intensification were analysed.
RESULTS: A total of 163 patients with T2DM who had intensification from human to analogue insulin were included in this study. HbA1c and FBS levels were significantly lower in analogue insulin. However, the differences were not clinically significant, as the mean reduction in HbA1c was less than 0.5%. Meanwhile, the total costs of analogue insulin for 3 months were higher.
CONCLUSION: There were no clinically significant improvements in patients' HbA1c and FBS after the intensification of insulin, despite the extra costs spent. Hence, it is vital to choose the right group of patients to receive an insulin analogue to maximise its benefit but at the most optimal cost.
