Mr-. Sanchez has no evidence of asbestos-related lung disease. Please feel free to call, if you have questions or ccmtients. JRH/rh 10/23/00 INITIAL EVALUATION PATIENT: FIDENCIO SANCHEZ DATE: 10/18/00 CHIEF COMPLAINT: "Asbestos exposure." HISTORY OF PRESENT u.TNRSS: This 72 year-old, retired laborer left work in 1991, where he was employed by Texas A&I University as a maintenance worker. He had worked there for sene 20 years doing minor repair jcfos involving plurrbing, windows, building and grounds maintenance, door repair, and other non-contracted jobs. He believes he may have had asbestos exposure in previous work for a contractor at the Celanese plant in Bishqp, Texas, where he was enployed for the nine years previously. During that work, he was a laborer, and fulfilled a variety of requirements, specifically remembering having mixed shovels of material with water to provide covering (presumably insulation) for heatconducting piping. He reports his work was inside and out, frequently involved with clean-up, and frequently dusty. He is unable to quantify exactly how much of his jab was spent doing work which dealt with insulation, and he did not apply insulation himself. He probably worked in the environment where insulators were working, but he cannot really provide those details. Prior to that time, he was enployed by a construction ccttpany in similar work, and before that, he was enployed in a slaughter house. He did not serve in the military other than the National Guard. When asked about his current health, he believes it is fairly good, reporting he gets tired easily, but that his only identified medical problem is diabetes mellitus. He has had diabetes for 14-15 years, and he checks his blood sugars at heme and generally keeps them between the 120 and 150 range. In 1997, he was hospitalized in Corpus Christi, Texas, where he underwent fourvessel bypass. It is difficult for me to establish the clinical circumstances that led up to that, and he has done "fine" since, and does not take any cardiac medications. In 1991, he was hospitalized for a procedure that neither he nor his daughter can define. His current medications only include an oral hypoglycemic. He is scheduled for cataract eye surgery in the future. FAMILY HISTORY: Remarkable for a sister and a mother with diabetes mellitus. SOCIAL HISTORY: He smoked for 4-5 years when he was young; this apparently was not significant. REVIEW OF SYSTEMS: Unremarkable. He does describe some ankle swelling involving the left leg only, but that was the site of his saphenous vein harvest for his coronary artery bypass surgery. PHYSICAL EXAMINATION: Generally, this is a pleasant, elderly man who appears approximately his stated age. Temperature is 96.1; respirations are 20 and unlabored; blood pressure is 138/78; height is 66 inches; and weight is 180 pounds. FIDENCIO SANCHEZ Initial Evaluation Page 2 HEAD, EYES, EARS, NOSE AND THROAT EXAMINATICN: normal tynpanic membranes anti nornel fundi bilaterally. The oropharynx is unremarkable. NECK: supple; no carotid bruits are heard; no JVD. CHEST EXAMINATICN: clear to auscultation. HEART: regular rhythm; a short systolic ejection nurttur is noted along the left sternal border; there is a well-healed median sternotomy wound. ABDOMEN: soft, non-tender, benign. EXTREMITIES: no edema. NEUROLOGIC EXAMINATICN: grossly unremarkable. Chest x-ray today demonstrates normal bony structures and the expected findings of a median sternotomy with evidence of coronary artery bypass via bypass rings. Staples are noted along the left cardiomediastinal silhouette consistent with left internal mammary artery implant. The parenchyma is unremarkable. The diaphragms are suggestive of hyperexpansion. No pleural abnormalities are noted. Pulmonary functioning testing is performed; spirometry is normal, although there is a suggested improvement (less than 15%) post-bronchodilator. Total lung capacity and diffusion are also normal. IMPRESSION: l. 2. Coronary artery disease; S/P coronary artery bypass grafting, 1997. Diabetes mellitus. RECOWENDATTCNS: 1. None.
