Cardiac mass in a patient with sigmoid adenocarcinoma: a metastasis?

Cardiac metastasis from a bowel malignancy seldom occurs and there is a limited number of case reports published on this subject. Although colorectal cancer is the third commonest malignancy in Malaysia, the incidence of cardiac metastasis has never been reported. We report a case of an elderly man with recently diagnosed adenocarcinoma of the sigmoid colon, who presented with congestive cardiac failure secondary to mechanical obstruction by a right atrial mass.

Right atrial tuberculoma: a diagnosis too late.

Solitary intra-cardiac cavity tuberculoma is extremely rare and often only diagnosed during a post-mortem. We report a case of right atrial tuberculoma causing right atrial outflow tract obstruction in an immune-compromised man. The diagnosis of cardiac tuberculoma was made through the detection of mycobacterium tuberculosis DNA by tuberculosis-polymerase chain reaction in the pericardial fluid.

Primary pigmented nodular adrenocortical disease.

Primary pigmented nodular adrenocortical disease (PPNAD) is a rare adrenal tumour causing corticotrophin-independent Cushing's syndrome. It occurs mainly in children and young adults. The histological examination is characterised by small pigmented micronodules on the adrenal cortex.

Reducing hypothermia in preterm infants with polyethylene wrap.

Background: Occlusive plastic applied immediately after birth to reduce evaporative heat loss has been proven effective in preterm infants <28 weeks' gestation. However its effectiveness on preterm infants >28 weeks' gestation has not been shown. This study aimed to determine the effect of occlusive wrap at birth on the temperature at neonatal intensive care unit (NICU) admission among infants of greater than or equal to 24 weeks' and less than 34 weeks' gestation.
