Forty-three patients with fractures of the thoracolumbar spine submitted to surgical treatment using the Harms method (dorsoventral operations) were studied prospectively with a follow-up of at least 12 months and evaluated on the basis of clinical and radiologic parameters and in relation to their professional activities. Thirty-five patients (81.3%) were males and eight (18.7%) females, ranging in age from 17 to 67 years (mean 34.08+/-11.51 years). Seven patients (16.2%) presented fractures of more than one vertebra, and associated lesions were present in 15 patients (34.8%). Monosegmental fixation was performed in 7 patients (16.3%), bisegmental fixation in 29 (67.4%), and trisegmental fixation in 7 (16.3%). No patient was submitted to any type of external immobilization during the postoperative period and all patients were allowed to sit up in bed and to walk as soon as their clinical conditions permitted. Thirty-nine patients were followed up for a period ranging from 12 to 36 months (mean 16.58+/-6.83 months). Four patients died during the postoperative period (three of pulmonary embolism and one of septicemia). Forty-two patients sat up in bed between the 2nd and 6th postoperative day, and those who did not present a disabling lesion (Frankel D or E) or other associated lesions walked between the 4th and 10th postoperative day (mean 6.14+/-6.06 days). The neurological signs and symptoms improved in 16 patients (37.3%), were unchanged in 26 (60.4%), and worsened in 1 (2.3%). Twenty-three patients (87.5%) who had no neurological damage (Frankel E) returned to their professional activities after respective periods of disability of 1 month (three patients), 2 months (four patients), 3 months (one patient), 4 months (seven patients), 5-7 months (five patients), 8-12 months (one patient), and more than 12 months (three patients). The ability to work of the 24 patients without neurological damage was 100% in 21, 50% in 2, and zero in 1. The ability to walk of this group of patients was 1-5 km for 4 and more than 5 km for the remaining 20 patients. The complications observed were death (four patients; three cases of pulmonary embolism and one case of septicemia), infection (two patients), Stevens-Johnson syndrome (one patient), and meningitis (one patient). The mean kyphosis of the fractured segment was 22.17 degrees +/- 10.97 degrees preoperatively, 8.55 degrees +/- 6.9 degrees postoperatively, and 10.30 degrees +/- 8.84 degrees on the occasion of late evaluation. No loss of correction occurred in 28 patients (71.8%), a 5 degrees loss was observed in 3 patients (7.6%), a 6 degrees loss in 3 (7.6%), a 7 degrees loss in 3 (7.6%), and a loss of more than 10 degrees in 2 (5.2%).

Injuries arising from ski-lift malfunction are rare. Most arise from skier error when embarking or disembarking, or from improper lift operation. A search of the literature failed to uncover any studies focusing specifically on ski-lift injuries. The purpose of this study was to identify and characterise ski-lift injury resulting in hospitalisation and comment on barriers to reporting and reporting omissions. New Zealand hospitalised injury discharges 2000-2005 formed the primary dataset. To aid case identification these data were linked to ACC compensated claims for the same period and the data searched for all hospitalised cases of injury arising from ski-lifts. 44 cases were identified representing 2% of snow-skiing/snowboarding cases. 28 cases (64%) were male and 16 (36%) female, the average age was 32 yrs (range 5-73 yrs). The majority of cases were snow-skiers (35 cases, 80%). Most of the injuries were serious, or potentially so, with 1 case of traumatic pneumothorax, one of pulmonary embolism (after jumping from a ski-lift) and 28 cases sustaining fractures (six to the neck-of-femur, one to the lumbar spine and one to the pubis). ICISS scores for all cases ranged from 1.00 to 0.8182 (probability of dying in hospital 0-18.18%). Only 14 (32%) cases could be easily identified from ICD-10-AM e-codes and activity codes in the discharge summary. The ICD-10-AM external cause code for ski-lift injury V98 ("other specified transport accidents") was only assigned to 39% of cases. The type of ski-lift could only be determined in 24 cases (55%).

The authors present a 76-year-old female with high blood pressure and hypercholesterolaemia as cerebrovascular risk factors, who received intravenous thrombolysis for an ischaemic stroke with a progressive neurological improvement. She was asymptomatic at 48 h and she was transferred to the neurology department where antithrombotic treatment was initiated. She began to sit the following day when she suffered a massive pulmonary embolism (PE). Cardiological study showed patent foramen oval persistence and the presence of an atrial septa aneurysm, and paroxysmal atrial fibrillation. The delay of the onset of the antithrombotic treatment could have been determinant for the massive PE. Thromboembolic complications may be seen after intravenous thrombolysis for ischaemic stroke. An accurate treatment is needed in order to avoid potentially threatening complications such as massive PE.

High intensity exercise is associated with several potentially thrombogenic risk factors, including dehydration and hemoconcentration, vascular trauma, musculoskeletal injuries, inflammation, long-distance travel, and contraceptive usage. These are well documented in case reports of venous thrombosis in track and field athletes. For mountaineers and those working at high altitude, additional risks exist. However, despite there being a high degree of vigilance for "classic" conditions encountered at altitude (eg, acute mountain sickness, high altitude pulmonary edema, and high altitude cerebral edema), mainstream awareness regarding thrombotic conditions and their complications in mountain athletes is relatively low. This is significant because thromboembolic events (including deep vein thrombosis, pulmonary embolism, and cerebral vascular thrombosis) are not uncommon at altitude. We describe a case of deep vein thrombosis and pulmonary embolism in a male mountain guide and discuss the diagnostic issues encountered by his medical practitioners. Potential risk factors affecting blood circulation (eg, seated car travel and compression of popliteal vein) and blood hypercoagulability (eg, hypoxia, environmental and psychological stressors [avalanche risk, extreme cold]) relevant to the subject of this report and mountain athletes in general are identified. Considerations for mitigating and managing thrombosis in addition to personalized care planning at altitude are discussed. The prevalence of thrombosis in mountain athletes is uncharted, but lowlanders increasingly go to high altitude to trek, ski, or climb. Blood clots can and do occur in physically active people, and thrombosis prevention and recognition will demand heightened awareness among participants, healthcare practitioners, and the altitude sport/leisure industry at large.

In most developed countries, coronary artery disease (CAD), mostly caused by atherosclerosis of coronary arteries, is one of the primary causes of death. From 1990s to 2000s, mortality caused by acute MI declined up to 50%. The incidence of CAD is related with age, gender, economic, etc. Atherosclerosis contains some highly correlative processes such as lipid disturbances, thrombosis, inflammation, vascular smooth cell activation, remodeling, platelet activation, endothelial dysfunction, oxidative stress, altered matrix metabolism, and genetic factors. Risk factors of CAD exist among many individuals of the general population, which includes hypertension, lipids and lipoproteins metabolism disturbances, diabetes mellitus, chronic kidney disease, age, genders, lifestyle, cigarette smoking, diet, obesity, and family history. Angina pectoris is caused by myocardial ischemia in the main expression of pain in the chest or adjoining area, which is usually a result of exertion and related to myocardial function disorder. Typical angina pectoris would last for minutes with gradual exacerbation. Rest, sit, or stop walking are the usual preference for patients with angina, and reaching the maximum intensity in seconds is uncommon. Rest or nitroglycerin usage can relieve typical angina pectoris within minutes. So far, a widely accepted angina pectoris severity grading system included CCS (Canadian Cardiovascular Society) classification, Califf score, and Goldman scale. Patients with ST-segment elevated myocardial infarction (STEMI) may have different symptoms and signs of both severe angina pectoris and various complications. The combination of rising usage of sensitive MI biomarkers and precise imaging techniques, including electrocardiograph (ECG), computed tomography, and cardiac magnetic resonance imaging, made the new MI criteria necessary. Complications of acute myocardial infarction include left ventricular dysfunction, cardiogenic shock, structural complications, arrhythmia, recurrent chest discomfort, recurrent ischemia and infarction, pericardial effusion, pericarditis, post-myocardial infarction syndrome, venous thrombosis pulmonary embolism, left ventricular aneurysm, left ventricular thrombus, and arterial embolism.
