A-V block in accidental hypothermia

His bundle electrocardiography was performed on a patient with accidental hypothermia on whom the standard electrocardiogram (ECG) showed absent P waves, prominent J waves and a slightly irregular rhythm. Sino-ventricular conduction and a prolonged AH interval not responsive to atropine were found. These abnormalities reversed with rewarming.     

Depression and the heart

Cardio Vascular disease (CVD) as well as depression are both highly prevalent disorders and both of them cause a significant decrease in quality of life and increase the economic burden for the patient. Depressed individuals are more likely to develop angina, fatal or non-fatal myocardial infarction, than those who are not depressed. Over the past decade, evidence has accumulated to suggest that depression may be a risk factor for cardiac mortality in patients with established coronary artery disease (CAD). The 'vicious cycle' linking CVD to major depression and depression to CVD, deserves greater attention from both cardio-vascular and psychiatric investigators.(1).     

Transcatheter closure of a residual aortopulmonary window through internal jugular vein access

The use of Amplatzer septal occluder for closing a residual aortopulmonary defect has been described. This is usually performed by femoral access. We report closure of a residual aortopulmonary defect using right internal jugular vein access in a patient who had no femoral access as a result of previous cannulation for surgical repair. The 1 cm defect was closed successfully using a 10 mm Amplatzer septal occluder.Technical difficulty anticipated was unfounded although it was more cumbersome than femoral access. Left to right cardiac defects including PDA and AP window are amenable to transcatheter closure through internal jugular vein access.     

Gastrointestinal mucormycosis—four cases with different risk factors, involving different anatomical sites

Mucormycosis of the gastrointestinal tract is a rare infection that usually occurs in patients who are immunocompromised and carries a high mortality. We report four cases of gastrointestinal mucormycosis seen over a one year period with different presentations, risk factors and different anatomical sites of involvement. A preoperative diagnosis was made only in one patient. All underwent surgery, three survived and one died postoperatively from multiorgan failure.
