During a recent investigation 1 by Dr. Stanton and myself of the lesions occurring in the aorta of the rabbit as the result of repeated injections of adrenalin, the heart muscle, in the few instances in which it was examined, was seen not infrequently to be the seat of very definite degenerative lesions and occasionally also of proliferative changes. The association of such conditions with an e...

OBJECTIVES We sought to quantify exercise-induced changes in patients with degenerative mitral regurgitation (MR), to examine the relationship between exercise-induced changes in MR and in systolic pulmonary artery pressure (PAP), and to identify their potential impact on symptom-free survival. BACKGROUND MR severity can change during exercise in patients with functional MR. Quantified change...

PURPOSE To evaluate the presence of fundus changes in degenerative myopia. METHODS Forty patients with refractive error of at least -6.00 diopters were selected for ophthalmologic examination followed by posterior pole photograph and echobiometry. RESULTS We studied 57 eyes of 37 patients with refractive error ranging from -6.25 to -28.50 diopters, with mean -14.05, and axial length ranging...

introduction:  laser  interstitial  thermotherapy  (litt)  is  an  internal  ablation  therapy  method  consisting of a percutaneous or intraoperative insertion of laser fibers directly into the liver tumor with  maximum diameter of 5 cm. in this treatment method, there isn’t any general information about the  relationship  between  increasing  the  exposure  power,  coagulation  and  carboniza...

  Schwannoma(neurilemmoma) is a benign tumor originates from Schwann cells. Ancient (degenerated) schwannoma is a long-standing schwannoma with degenerative changes. Head and neck region is one of the most common sites for nerve sheath tumors but intraosseous schwannoma is rare. The mandible is the most common site of occurrence for this lesion. We report a rare case of intraosseous ancient sc...

Following the rapid extension of electroencephalography in the investigation of all forms of intracranial affection in clinical neurology, it soon became apparent that tumours in the posterior fossa greatly complicated the electroencephalogram. Numerous early publications, including the work of Grey Walter (1936, 1937, and 1938) and that of Bickford and Baldes (1947), gave conflicting informati...

OBJECTIVE To determine the relationship between whole body vibration (WBV) induced helicopter flights and degenerative changes of the cervical and lumbar spine. METHODS We examined 186 helicopter pilots who were exposed to WBV and 94 military clerical workers at a military hospital. Questionnaires and interviews were completed for 164 of the 186 pilots (response rate, 88.2%) and 88 of the 94 ...
