Chromosomes In Multiple Endocrine Neoplasia Type 2 Syndromes, Daniel L. Van Dyke, V. Ramesh Babu, Charles E. Jackson
Chromosomes In Multiple Endocrine Neoplasia Type 2 Syndromes, Daniel L. Van Dyke, V. Ramesh Babu, Charles E. Jackson
Henry Ford Hospital Medical Journal
In 19 patients from nine MEN-2A families, high-resolution C-banded chromosome studies have revealed a visible deletion within sub-band 20p12.2, yet no abnormality was observed in a 10th family. A deletion indistinguishable from that in MEN-2A was observed in five patients from three MEN-2B families but not in two other MEN-2B families. We found no abnormality in the entire karyotype of the four MEN-1 patients studied. These findings suggest that the mutation in most MEN-2 patients is a visible deletion in the short arm of chromosome 20.

Research Vistas In The Multiple Endocrine Neoplasia Syndromes, John J. Mulvihill
Henry Ford Hospital Medical Journal
Progress in understanding the single gene, cytogenetic, and multifactorial traits that predispose to human cancer suggests possible new directions for research in the multiple endocrine neoplasia (MEN) syndromes. Among the other 200 or so monogenic disorders associated with human neoplasia, advances have come from further delineation of syndromes by various clinical specialists, the recognition of subtypes of syndromes previously thought to be homogeneous, the search for in vitro manifestations of the mutant gene in fibroblasts, and the establishment of cell, tissue and patient registries and of voluntary lay organizations to serve as advocates for the disease. With regard to cytogenetics, …

A collaborative group for the study of multiple endocrine neoplasia type 2 (MEN-2) syndromes comprised of clinicians and laboratory scientists has been set up in the United Kingdom. Its aims are 1) to provide a basis for collaborative work on MEN-2; 2) to establish a register of patients; 3) and specifically to conduct studies aimed at defining the best policy for screening the families of apparently sporadic patients, to establish radioimmunoassays for family screening, and to identify large kindreds for genetic linkage studies using DNA polymorphisms.
Screening For Hereditary Medullary Cancer In Denmark, Kristian Emmertsen
Screening For Hereditary Medullary Cancer In Denmark, Kristian Emmertsen
Henry Ford Hospital Medical Journal
Screening of first-degree relatives of patients with medullary thyroid cancer (MTC) gave normal values of pentagastrin-stimulated serum calcitonin and 24-hour urinary catecholamine levels in the relatives of 18 of 22 patients. This result is considered to be valid evidence for sporadic MTC. Absence of C-cell hyperplasia maybe another indication of sporadic MTC. Four hereditary MTCs were represented by one fully expressed MEN-2B patient without affected relatives, one fully expressed MEN-2A case in one family, and two first cousins with MTC as the only MEN-2A lesion in another family. Fourteen relatives of the MEN-2A patients had elevated serum calcitonin levels, and …

Through nationwide surveys, we collected and analyzed 242 patients of medullary thyroid carcinoma (MTC). Included were 40 patients with multiple endocrine neoplasia type 2A (MEN-2A), six patients with MEN-2B, and 36 patients with only MTC having a positive family history (82 total patients in the hereditary group). Ten-year survival rates were 81.5% for all cases, and 97.5% and 76.1% for the hereditary and the sporadic group, respectively. Epinephrine/norepinephrine ratio in the urine was found to be a good indicator of the adrenomedullary hyperfunction in patients with hereditary MTC. At least one patient in each family with hereditary MTC had overt …

Scintigraphy With 1-131 Mibg As An Aid To The Treatment Of Pheochromocytomas In Patients With The Multiple Endocrine Neoplasia Type 2 Syndromes, James C. Sisson, Brahm Shapiro, William H. Beierwaltes
Henry Ford Hospital Medical Journal
We reviewed the scintigraphic images made after injections of 1-131 metaiodobenzylguanidine (MIBG) or 1-123 MIBG in patients with multiple endocrine neoplasia (MEN) types 2A and 2B. The information we obtained was applied to three questions about the treatment of pheochromocytoma in patients affected with these syndromes. Our first question "When should adrenal gland(s) be removed?" was not directly answered. However, adrenalectomy generally should not be contemplated unless distinct abnormalities are present in the scintigraphic images. With experience it may be possible to approximate, from the stage of pheochromocytoma depicted by scintigraphy, how many years will elapse before symptoms or hypertension …

Using recombinant DNA techniques, we analyzed the structure of human calcitonin (CT)-encoding DNA. The sequence of nucleotides derived from the messenger RNA (mRNA) predict the amino acid sequence of the entire human CT precursor protein. The complete CT gene could be isolated from a DNA library of the human genome. The CT precursor encoding sequences (exons) as well as the noncoding intervening sequences (introns) could be identified. Another sequence, called human calcitonin gene-related peptide (hCCRP), could be located near this CT-encoding DNA. A genomic fragment encoding hCCRP was used as a probe to detect and isolate the corresponding mRNA in …

Developing An Integrated Natural Language Database For Gastrointestinal Disease, Peter J. Feczko, Laurens V. Ackerman, Robert D. Halpert, Stuart M. Simms
Henry Ford Hospital Medical Journal
Using a mainframe computer connected to the Henry Ford Hospital computer network, we developed a database for gastrointestinal disease which includes data from radiologic and endoscopic gastrointestinal examinations, along with corresponding pathologic diagnosis. Because of the large volume of procedures in our practice, we developed several unique features for our system. The user enters data by responding to a series of question-and-answer sets constructed by the clinical staff, who do not have experience in computer programming. Data is stored in a hierarchical format using natural language. Boolean logic is used to retrieve data so that different procedures can be correlated …

Computer-Assisted Methods For Design Optimization Of Cardiac Bioprosthetic Valves, Mohamed S. Hamid, Hani N. Sabbah, Paul D. Stein
Computer-Assisted Methods For Design Optimization Of Cardiac Bioprosthetic Valves, Mohamed S. Hamid, Hani N. Sabbah, Paul D. Stein
Henry Ford Hospital Medical Journal
Excessive mechanical stresses on valvular leaflets are considered an important factor in the degeneration of cardiac porcine bioprosthetic valves. This study describes a computer-assisted numerical model of a bioprosthetic valve which estimates the magnitude and distribution of leaflet stresses. The study also describes our initial attempts to determine the influence of stent height upon leaflet stresses. Whereas lowering stent heights has been suggested to improve hemodynamics in the bioprosthetic valve region, results indicate that an increase in leaflet stresses can accompany reductions of stent height.

Obtaining appropriate information in a timely fashion in medical practice has always been a burden for the practitioner. In a large hospital which undertakes major computer projects, this burden is intensified because information is not always available in a form directly usable by the physician or support personnel; it is now accumulated on diverse magnetic media where it is moved and processed as electronic pulses. This paper describes a solution which freely allows continued automation at different rates throughout a large hospital while expediting the movement of information where it is needed in a form understandable by the recipient.

Intracerebral Hemorrhage After Carotid Endarterectomy, José Biller, Andrew C. Hayes, Fred N. Littooy, William H. Baker
Henry Ford Hospital Medical Journal
Intracerebral hemorrhage (ICH) is a rare complication of carotid endarterectomy (CE). In our multicenter series of 1,180 CE (Baker-Littooy), three ICH occurred, of which two were fatal. One patient was receiving anticoagulants because ofa prosthetic aortic valve; another had rupture of a known ipsilateral intracranial aneurysm. Both occurred more than six weeks postoperatively. The third patient, who was hypertensive, had a nonfatal ipsilateral thalamic hemorrhage on the third postoperative day. Though these three patients represent only 0.25% of our series, they constitute 12% of our total strokes. ICH constitutes the largest percentage of nontechnically-related strokes and noncardiac deaths after CE.

Henry Ford Hospital Medical Journal
The Vascular Registry of Henry Ford Hospital was initiated by one of the authors in 1957 to provide a consistent and accurate method of documenting and correlating the clinical results of the treatment of occlusive and aneurysmal arterial diseases. Data collection for each patient includes demographic information, treatment of clinical problems, and followup observations. Initially, the system consisted of keypunch cards and eventually magnetic tape processing. By 1980, it was necessary to further update the system because of the increase in patient volume, the need to minimize manual manipulations, and the demand for research data. The present system uses institutional …

Henry Ford Hospital Medical Journal
This article describes our experience in the development and implementation of a computerized information system specifically designed for a Division of Nephrology and Hypertension. Specific issues related to planning and implementation are discussed, and potential pitfalls in setting up such a system are addressed. The combination of a mainframe and a miniframe as integral parts of the system and the development of peripheral support in specific applications using a personal microcomputer are also described. The important area of user/computer interface and of user motivation is discussed in the light of the experience acquired while implementing the current system.
Cardiac Papillary Fibroelastoma: A Source Of Coronary Artery Emboli And Myocardial Infarction, Gerald Fine, Shoba R. Pai
Cardiac Papillary Fibroelastoma: A Source Of Coronary Artery Emboli And Myocardial Infarction, Gerald Fine, Shoba R. Pai
Henry Ford Hospital Medical Journal
Cardiac papillary fibroelastomas, although generally small and asymptomatic, have been suspected of being responsible for cerebral accidents, angina, and sudden death. The diagnosis of tumor embolization, considered in a number of cases, has been based on circumstantial evidence in all instances except for one case of sudden death due to embolism to the left anterior descending coronary artery. In all other cases, angina and sudden death have been related to a ball valve-type obstruction of a coronary ostium by tumor. The present case documents tumor embolism to peripheral right coronary arteries with associated, clinically silent myocardial changes.

Immunology Of The Acquired Immunodeficiency Syndrome, Patrick W. Mclaughlin, Carl B. Lauter
Henry Ford Hospital Medical Journal
The Acquired Immunodeficiency Syndrome (AIDS) first recognized in 1981, has been extensively studied, and the most recent studies have demonstrated that its defects extend well beyond the apparent deficient cell-mediated immunity to include humoral immunity, autoimmunity, and abnormal immunoregulation. The recent discovery of a retrovirus, HTLV III, as a possible etiologic agent is discussed in relation to other viruses known to cause immunodeficiency. Simian AIDS, an animal model of virus-induced immunodeficiency, is also discussed. Recommendations are made regarding the interpretation and limitations of immune testing in AIDS, including a discussion of how apparently healthy homosexuals and groups at risk develop …
