A 40-year-old male pilot presented to the clinic for his physical. He denied any symptoms on initial questioning. Subsequent ... | 18,751,603 |
[Venous thromboembolism risk in medical inpatients]. | Venous thromboembolism is one of the main causes of morbidity and mortality in many diseases, either in medical or in surgical wards. The aim of this study is to determine its frequency in a medical ward and to find all the patients who need a prophylaxys. We examined all the inpatients admitted in our Department durin... | 18,751,614 |
Impact of ethnicity and MTHFR genotype on age at onset of coronary artery disease in women in Israel. | The C677T mutation in the methylenetetrahydrofolate reductase (MTHFR) gene is associated with early onset of coronary artery disease in some populations with certain ethnic backgrounds. However, data on its effect on CAD development in women are limited and conflicting. To investigate the effects of the MTHFR C677T mut... | 18,751,630 |
High-resolution multicontrast-weighted MR imaging from human carotid endarterectomy specimens to assess carotid plaque components. | The American Heart Association modified classification for atherosclerotic plaque lesions has defined vulnerable plaques as those prone to rupture. The aim of our study was to assess the sensitivity and specificity of 1.5-T magnetic resonance imaging (MRI) in the evaluation of the characteristics of plaque components. ... | 18,751,713 |
Immune privilege of allogeneic neuroretinal transplants in the subconjunctival space. | The extent of site and tissue-associated immune privilege is of great interest in transplantation experiments involving the CNS. In the present paper we have explored neuroretinal immune privilege by transplantation to a non-immune privileged site. Fetal and adult full-thickness rabbit neuroretinal grafts were placed i... | 18,751,716 |
Functional features of the C-terminal region of yeast ribosomal protein L5. | The aim of this study was to analyze the functional importance of the C-terminus of the essential yeast ribosomal protein L5 (YrpL5). Previous studies have indicated that the C-terminal region of YrpL5 forms an alpha-helix with a positively charged surface that is involved in protein-5S rRNA interaction. Formation of a... | 18,751,732 |
Fear, fatalism and breast cancer screening in low-income African-American women: the role of clinicians and the health care system. | African-American women have the highest breast cancer death rates of all racial/ethnic groups in the US. Reasons for these disparities are multi-factorial, but include lower mammogram utilization among this population. Cultural attitudes and beliefs, such as fear and fatalism, have not been fully explored as potential ... | 18,751,758 |
Diffuse abdominal and port site pain caused by the connecting tube in gastric banding. | Laparoscopic adjustable gastric banding is an effective treatment for morbid obesity and has become the most widespread bariatric operation. Complications such as stomach slippage, band erosion or dislocation, pouch dilatation and port complications have been widely reported and discussed. We report two similar cases o... | 18,751,761 |
Body contouring surgery following bariatric surgery and dietetically induced massive weight reduction: a risk analysis. | This study analyzed the impact of weight reduction method, preoperative, and intraoperative variables on the outcome of reconstructive body contouring surgery following massive weight reduction. All patients presenting with a maximal BMI >/=35 kg/m(2) before weight reduction who underwent body contouring surgery of ... | 18,751,762 |
The Hospital for the Ruptured and Crippled moves east on 42nd Street 1912 to 1925. | In 1912, the Hospital for the Ruptured and Crippled (R & C) moved to its third location since its founding in 1863. It was a newly constructed six-story building on 42nd Street between Second Avenue and First Avenue. At the time Dr. Virgil Gibney, the second Surgeon-in-Chief, was 65 years of age and had already ser... | 18,751,783 |
Prevalence of major life events among patients and community dwellers. | Life events have been shown to be associated with health and illness. We studied the number of life events experienced by hip fracture patients, nonfracture rheumatology patients, and community-dwelling asymptomatic residents in the year before interview. Fifty-four hip fracture patients, 63 ambulatory patients, and 11... | 18,751,810 |
What is the role of magnetic resonance imaging in the evaluation of total hip arthroplasty? | MRI has been shown to be an extremely effective instrument in the management of painful hip arthroplasty. Its superior soft tissue contrast and direct multiplanar acquisition compared to computerized tomography (CT) and radiographs allows for reproducible visualization of periacetabular osteolysis, demonstrating compre... | 18,751,814 |
A shearing osteochondral fracture of the humeral head following an anterior shoulder dislocation in a child. | A dislocation of the shoulder joint is rare in children with an open physis. The fractures associated with an anterior dislocation generally reported in the literature have been Hill-Sachs lesions, avulsions of the greater tuberosity and glenoid fractures. We present a case of a previously unreported shearing osteochon... | 18,751,816 |
Effect on deep venous thrombosis with flexion during total knee arthroplasty. | This study investigates the relationship between intraoperative extreme flexion and tibia-femoral dislocation during total knee arthroplasty on the prevalence of postoperative deep venous thrombosis. Knees were randomized into two groups. The control group underwent the procedure according to normal protocol, which kep... | 18,751,828 |
Histological and molecular structure characterization of annular collagen after intradiskal electrothermal annuloplasty. | The mechanism of pain relief of intradiskal electrothermal annuloplasty (IDET) in the treatment of lumbar diskogenic pain is uncertain. Theories include sealing of annular fissures via collagen denaturation and contraction. Prior studies offer conflicting qualitative data on the ability of IDET to denature collagen. Th... | 18,751,846 |
The Eftekhar and Kerboul classifications in assessment of developmental dysplasia of the hip in adult patients. Measurement of inter- and intraobserver reliability. | To measure the inter- and intraobserver reliability of two radiologic classification systems in the evaluation of severity of osteoarthritis secondary to developmental dysplasia of the hip in adult patients and to compare these systems to historically published data on two more commonly used classification systems desc... | 18,751,859 |
The one year incidence of postoperative myocardial infarction in an orthopedic population. | The diagnosis of a postoperative myocardial infarction (PMI) is important in the orthopedic population because these events can be associated with significant cardiac morbidity. Plasma troponin I (cTnI) analysis has markedly increased our ability to detect myocardial damage. Using cTnI analysis for evidence of a PMI, w... | 18,751,868 |
