ABSTRACT
Para swimmers with limb deficiency are faced with the particular situation that they must use their head to finish each competition by a hit to the wall. Repetitive head impacts may impair behavioral and brain functions. We therefore investigated neurobehavioral functions of a Para swimmer with dysmelia before and after repetitive head impacts (T1) and without (T2). Average head impact at T1 constituted 13.6â¯g with a mean impact force of 6689.9â¯N. Behavioral and brain functions decreased from pre to post at T1 but not at T2. Para swimmers with limb deficiency are therefore affected from the same consequences onto brain health that are observed after repeated sport-related concussions.

Osteosarcomas of the cranial bones need a large surgical radical resection. The best option to reconstruct mandible defect after resection is the free fibula flap. In our patient an acute ischaemic leg occurred just after the free fibula flap harvest for mandible reconstruction. The abnormal distribution of the calf arteries leads to catastrophic consequences. The peroneal artery could be the main dominant artery of the leg in a small number of patients. We reported an extremely rare case of "peronea magna", described in less than 0.2% of the global population. A careful pre-operative workup of the calf vessels is required in all the patients who need free fibula flap harvest.

A 72-yr-old man was electively admitted for cardiac revascularisation 6 weeks after an inaugural inferior infarct. His physical examination and laboratory test were unremarkable. According to his coronarography the patient was programmed for an off pump coronary artery by-pass. During surgery the heart was found to be completely herniated in the left chest, passing on the posterior aspect of the phrenic nerve. Symptomatology and complications of congenital pericardial defects are reviewed.
