Between Jan. 1, 1976 and Dec. 31, 1981, 257 patients (age range from 21 to 65 years) with osteoarthritis of one or both hips were treated with ceramic hip replacement (Mittelmeier type). The cause of the osteoarthritis was variable. Hip replacement was carried out for the following conditions: rheumatoid arthritis including ankylosing spondylitis, aseptic necrosis of femoral head including post-traumatic and idiopathic forms, osteoarthritis of unknown origin, osteoarthritis following dysplasia or subluxation of the hips and loosened cemented hip prosthesis. The operative technique is described. Full weight bearing is not permitted for 16 weeks postoperatively, but mobilization and isometric exercises begin 2 days after operation and isotonic exercises are introduced later. Complications included fracture of the femoral shaft during operation, fracture of the acetabulum, protrusion, dislocation and infection early after operation (within 16 weeks) and aseptic loosening and pulmonary embolism (after 16 weeks). The results with this new type of hip replacement are encouraging. Good results based on patient satisfaction were obtained in 79% and poor results in 13%.

One hundred and two uncemented total hip arthroplasties using an anatomic femoral component were performed and followed postoperatively in 96 patients for an average of 35 months (range 24-44). Clinical assessment was performed by a Harris Hip Score (HHS) and standardized radiographs. The primary diagnoses were: osteoarthritis, 86 patients; traumatic arthritis 2; inflammatory arthritis 2; congenital hip dysplasia 5 and avascular necrosis 1. There were 44 males and 52 females. The purpose of this study was to prospectively study whether anatomically designed cementless femoral stems reduce the incidence of thigh pain and limp in the early period after total hip arthroplasty. The average pre-operative HHS was 47, the average pain score was 16 and average function score 25. At the last follow-up the average HHS was 93, average pain and limp at one year was 3.5% and was only slight to mild; this decreased to 1.9% at last follow-up. Radiographic findings included calcar rounding 75%, pedestal formation 40%, distal cortical hypertrophy 20% and incomplete radiolucencies in 35%. No endosteal erosions were seen. Heterotopic ossifications were present in 2 patients, one of which required excision. Complications consisted of dislocations treated closed, 3 intra-operative fractures without sequellae, 1 traumatic peri-operative fracture which required surgery without further complication and 1 pulmonary embolism. One patient required revision for leg length discrepancy. There were no infections. The results of this study indicate that this cementless, anatomically designed femoral component can provide satisfactory, early pain relief and function in this younger, active patient population.(ABSTRACT TRUNCATED AT 250 WORDS)

A 57 year-old patient presented with a Barrett's epithelium over the length of 18 cm. We found the typical functional changes of acid reflux and hypomotility in the distal esophagus. There was a history of chemotherapy for seminoma 30 years ago. Because of the repeated finding of severe dysplasia surgery was proposed. The patient died in the postoperative period with the signs and symptoms of pulmonary embolism. There was no invasive tumor found in the resected part of the esophagus. Main aspects of the etiology and histological characterism of Barrett's esophagus and the indication for surgery in cases with severe dysplasia are discussed.

Between 1988 and 1991, 40 Wagner SL femoral revision stems were implanted at the Orthopaedic Departments of the University of Basel and of the Kantonsspital Liestal, Switzerland. The indications were: 27 cases of extensive bone resorption and destruction of the proximal prosthetic bed, seven periprosthetic fractures, two Girdle-stone situations after removal of infected total hip arthroplasty (THA), 1 case each of primary arthroplasty for congenital dysplasia of the hip, failed osteosynthesis of a pertrochanteric fracture, subtrochanteric femoral fracture and femoral fracture with subsequent osteomyelitis. The average follow-up time was 47 months. The average age of the patients was 70 years (range 37-85 years). The average preoperative hip score was 32 points, postoperative 78 points. We noted to severe complications such as thrombosis, pulmonary embolism or nerve injury. No case of early infection has occurred to date. Four hips required further revision, one after a haematogenous infection of the prosthesis 2 years after implantation, one 4 weeks after surgery because of a stem which was significantly undersized compared with the medullary canal of the femur. Two hips were revised after 3 and 4 years, respectively, for continuous subsidence and loosening in the medullary canal. Both revisions were successfully achieved using a femoral component of larger diameter. We recommend the Wagner SL femoral revision stem, not as a routine procedure to treat loosening, but for patients with severe femoral bone resorption after THA or periprosthetic fractures, those in the Girdlestone situation and geriatric patients with pertrochanteric or subtrochanteric fractures.

Sudden death during sports activities is extremely rare in athletes and sportsmen. Its occurrence was calculated at 0.77 to 13 deaths per 100,000 sportsmen/year. The most frequent causes were coronary heart disease, coronary muscular bridges, congenital coronary artery anomalies, subarachnoid hemorrhage, hypertrophic cardiomyopathy, arrhythmogenic right ventricular dysplasia, Marfan syndrome, aortic coarctation, myocarditis, pulmonary embolism, aortic stenosis, mitral valve prolapse and WPW syndrome. Clinical examination nearly identifies all cases of aortic stenosis, mitral valve prolapse with regurgitation, and aortic coarctation but misses the majority of cases of hypertrophic cardiomyopathy and coronary artery diseases. The use of Chest x-rays, ECG, Stress Test and Echocardiogram will provide the identification of most cases with increased risk of death. Although costs are not limited for professional athletes, this strategy does not totally overcome the problem because diagnostic errors are frequent (false positives and false negatives). Therefore it is important to admit the failure of these screening procedures and the necessity to adapt the strategy to cost-efficiency and time-efficiency in this population.

The authors report a case of cardiomyopathy of the right ventricle revealed suddenly in a presentation of pulmonary embolism in relation to a large thrombus that developed in an enormous, extremely hypokinetic right ventricle. The scenario suggests dysplasia without rhythm disorder. This case allows a discussion on the multiple variants of arhythmogenic dysplasia of the right ventricle.

Spontaneous hemothorax is a rare and potentially lethal neurofibromatosis' complication. Several pathological mechanisms may explain the associated vasculopathy: a) direct vascular invasion from adjacent tumors such as Shwannoma, neurofibroma or neurofibrosarcoma; b) vascular dysplasia with stenotic or aneurysm formation. Other mechanisms involved may include pleuropulmonar pathologies (necrotizing infections, pulmonary embolism, endometriosis, neoplasms) and blood dyscrasias. The authors describe a case of a 33 years old female, who went to the ER Service complaining with right persistent hemithoracic pain, extending to the ipsilateral shoulder and shoulder blade, without aggravation or relieving factors, since the last 8 days.

Fibromuscular dysplasia or fibromuscular hyperplasia is a rare non-atherosclerotic and non-inflammatory vascular disease that primarily involves medium-size and small arteries, most commonly the renal and carotid arteries, and less frequently the vertebral, iliac, subclavian or visceral arteries (mesenteric, hepatic, splenic). Antiphospholipid syndrome is one of the most commonly acquired hypercoagulable states, defined by the association of laboratory evidence of anti-phospholipid antibodies with arterial or venous thrombosis or recurrent pregnancy losses. The presence of these antibodies is associated with an increased risk of thromboembolic phenomena, including peripheral thrombophlebitis, pulmonary thromboembolism, stroke, retinal artery occlusion, myocardial infarction, placental thrombosis and Budd-Chiari syndrome. In this report we discuss the uncommon case of a young male patient with both antiphospholipid syndrome and fibromuscular dysplasia that came to our attention for pulmonary embolism and "angina abdominis" due to occlusion of three mesenteric vessels. The possible relationship between antiphospholipid syndrome and fibromuscular dysplasia encountered in our patient still remains unclear. We treated the patient as if he had the two different diseases. After partial failure of endovascular surgery, the patient underwent surgery with reimplantation of three visceral arteries to the aorta. Subsequently he was treated with stent placement after development of a re-stenosis of one of the three reimplanted visceral arteries. The patient was treated conservatively for antiphospholipid syndrome with anticoagulant oral therapy for life.

A pulmonary embolus clogs the artery that provides blood supply to a part of the lung. The embolus not only prevents the exchange of oxygen and carbon dioxide but also decreases blood supply to the lung tissue itself, potentially causing the tissue to die (infarct). A 52-year-old man presented with syncope and anxiety. He had sinus tachycardia and dilated right ventricle with trabeculations. A differential diagnosis of arrhythmogenic right ventricular dysplasia and pulmonary embolism prompted CT angiography, which revealed a bilateral massive pulmonary embolism. The patient was treated successfully with thrombolytic drugs.
