Aims: The Windscale (UK) fire of 1957 carried radioactive fallout according to the then prevailing wind patterns, in a North-Easterly direction across the Nordic countries, toward Norway. The male:female ratio at birth (M/F) is known to be increased after parental exposure to ionising radiation due to foetal losses that affect female more than male pregnancies. This study was carried out in order to ascertain whether the Windscale fire had any effects on M/F and birth rates in the United Kingdom and Scandinavia.

Clinical medical examinations are difficult. Courses that attempt to instil such clinical examination skills are expensive, and this is even more so for Maltese graduates who must perforce travel by air from the island of Malta to such venues. This year (2012) was a landmark year with a record seven Maltese candidates planning to take the MRCPCH examination, and it was therefore decided to set up a mock clinical exam under true examination conditions in Malta.

Maltese children are frequently exposed to tobacco smoke through passive and personal smoking. In the phase 3 ISAAC study questionnaire, we enquired about passive smoking to the parents of 3816 (80% response rate) 5- to 8-yr-old children and about passive and personal smoking to 4139 (90% response rate) 13- to 15-yr-old participating children. Thirty-one percent of 5- to 8-yr olds were passive smokers with their father more likely to be the smoker (p < 0.

Background: Coronary angiography remains the gold standard for the investigation of coronary artery disease, and is carried out in multiple, predefined stationary views, at different angulations around the patient, for both left and right coronary arteries. Dual axis rotational coronary angiography (DARA) is an alternative technique wherein the c-arm rotates around the patient in a preprogrammed single acquisition, exposing the entire coronary artery at different angulations. The DARA system has been recently installed in the Cardiac Catheterisation Suite at Mater Dei Hospital, Malta, where a monoplane and a biplane machine are available.

It is accepted practice to close large patent arterial ducts (PDA) with Amplatzer duct occluder devices, with extremely low rates of residual PDA. We report a child who required device closure of PDA with two Amplatzer PDA devices on two separate occasions, despite the first device deployment being a standard placement of an appropriately sized Amplatzer device in the usual position.
