In the "24-hour Cross Country Ski Race of Pinzolo" skiers attempt to cover as long as possible distances within 24 hours. Cardiac and metabolic changes of 6 volunteer cross country skiers, aging 29 to 39 years, participating to the individual competition, were analysed. All skiers had negative clinical examination and resting standard 12-lead ECG, except for one who had a midsystolic click on auscultation suggesting the presence of mitral valve prolapse. They were submitted to 48-hour Holter monitoring (HM) going from 3:00 p.m. of the day before the race up to one hour after the end of competition. The period of HM going from 3 p.m. of the day before to 1.00 p.m. of the day of race (one hour before the start) was utilized as control as concerns arrhythmias, ST-T wave and QT interval changes observed during the period of competition. In all 6 skiers, standard 12-lead ECG was again recorded on completion of race. The following serum indexes were obtained in basal conditions and within one hour after the end of race: electrolytes (Na+, K+), Myoglobina (MG) and the enzymes GOT, GPT, LDH, CK and CK-MB. Complete urine analysis was also obtained before and immediately after the race. The distance covered by the skiers ranged from 189 to 260 Km, except for the skier with systolic click who covered 95.7 Km within 12 hour and then retired from the race for acute pain of knee.(ABSTRACT TRUNCATED AT 250 WORDS)

Introduction. Fluid-attenuated inversion recovery hyperintense vessels (FHVs) can be seen in patients with occlusion or severe stenosis of the cerebral arteries. FHVs are known to reflect stagnant or slow blood flow within the cerebral artery. Case Report. A 75-year-old woman presented with suddenly developed gait disturbance. She had a history of hypertension, heart failure, and dementia. Brain MRI demonstrated FHVs within both middle cerebral arteries (MCAs). However, there was no acute ischemic lesion and severe stenosis or occlusion of the cerebral arteries. In the baseline routine laboratory investigations, the AST, ALT, and B-type natriuretic peptide levels were elevated. Transthoracic echocardiography (TTE) showed mitral valve prolapse with severe regurgitation. Blood pressure control and conservative management for ischemic hepatitis were performed. After 7 days, the transaminase levels were normalized, and the patient was able to walk with normal gait. Conclusions. In this patient, underlying chronic cerebral hypoperfusion and additionally decreased systemic perfusion seemed to provoke ischemic hepatitis and contribute to the development of FHVs.
