Henry Ford Hospital Medical Journal

Since 1975, six families with the MEN-2A syndrome including 66 patients have been identified in The Netherlands. All these patients underwent thyroidectomy for C-cell hyperplasia and/or medullary thyroid carcinoma (MTC); eight were symptomatic (Group A), 51 were relatives of patients found to be affected (Group B), and seven had had a negative screening test that became positive (Group C). To assess the effect of screening, we compared these groups with respect to the occurrence of metastatic MTC at thyroidectomy and the results of the postoperative calcitonin (CT) tests. We found that 87% of Group A, 37% of Group B; and …

Characteristics Of A Family With The Men-2a Syndrome, Harm R. Haak, Arie C. Nieuwenhuijzen Kruseman

Henry Ford Hospital Medical Journal

Results of screening and follow-up in a family with the MEN-2A syndrome are described. Fourteen (83%) subjects at risk were affected with medullary thyroid carcinoma (MTC). Asymptomatic pheochromocytoma and parathyroid hyperplasia were found in two instances each. Intrathyroidal MTC without metastases was found in the four youngest subjects and was associated with normal basal but abnormal pentagastrin-stimulated calcitonin (CT) levels. In the ten subjects with abnormal basal CT levels, metastatic spread to at least regional lymph nodes was found. In eight of these ten subjects, total thyroidectomy with excision of affected lymph nodes and additional radioiodine did not return CT …

Multiple Endocrine Neoplasia Type 2a: A Northern Ireland And Australian Family, David R. Hadden, Fergus O'Reilly, Laurence Kennedy, Colin Russell

Henry Ford Hospital Medical Journal

A Northern Ireland/Australian family with multiple endocrine neoplasia type 2A is described. Three members of the first generation studied have died, two men (aged 35 and 51) as a result of metastatic medullary thyroid carcinoma and one woman (the index case, aged 50) due to hypertensive complications during thyroidectomy from an undiagnosed pheochromocytoma. All members of this family found by screening to have either medullary thyroid carcinoma or pheochromocytoma, or both, have been asymptomatic for their disease.

Screening For Early Asymptomatic Pheochromocytoma In Men-2, Margareta Telenius-Berg, Bertel Berg, Bertil Hamberger, Sten Tibblin

Henry Ford Hospital Medical Journal

Pheochromocytoma is a major cause of morbidity in multiple endocrine neoplasia type 2. We recommend a similar diagnostic screening approach for early asymptomatic pheochromocytoma as is generally accepted for asymptomatic medullary thyroid carcinoma. We present a new provocative test for early asymptomatic pheochromocytoma. Plasma epinephrine levels and epinephrine/dopamine ratios after physical exercise seem to have higher sensitivity than basal plasma catecholamine levels. Specificity is high especially for discrimination from neurovegetative lability, which is the clinically most important differential diagnosis.

Calcitonin Gene-Related Peptide And Calcitonin In Men-2 And Sporadic Pheochromocytomas: An Immunohistochemical Study, Lis Johannsen, Henrik Daa Schroder, Soren Schifter

Henry Ford Hospital Medical Journal

Ten pheochromocytomas (five from patients with multiple endocrine neoplasia type 2 and five sporadic) were stained immunohistochemically with antibodies to calcitonin (CT) and calcitonin gene-related peptide (CGRP) by means of the peroxidase-antiperoxidase method. CGRP positive cells were found in variable numbers in all of the investigated tumors. No demonstrable difference was noted between the hereditary tumors and the sporadic tumors. Staining with CT antibody also showed cells with a positive reaction in eight of ten tumors. The distribution of the two peptides was similar, and in some cells their coexistence was visualized. Pheochromocytomas thus represent an alternative site to medullary …

Calcitonin Gene Peptides: The Diagnostic Value Of Measurement In Medullary Thyroid Carcinoma, Samia I. Girgis, Catherine Lynch, Carmel J. Hillyard, John C. Stevenson, Patricia A. Hill, David W. R. Macdonald, Iain Macintyre

Henry Ford Hospital Medical Journal

The calcitonin gene encodes a family of peptides, at least three of which normally circulate in man: calcitonin (CT), a calcium-lowering hormone; katacalcin (KC), a peptide of unknown function; and calcitonin gene-related peptide (CGRP), a neuropeptide and potent vasodilator. In a study of 45 patients with medullary thyroid carcinoma (MTC), plasma CGRP was elevated in approximately 50% of cases. Furthermore, CGRP levels did not correlate with CT levels. However, plasma KC was elevated in all cases, with a good correlation with CT levels, as has been noted previously. Measurement of CT or KC appears to be superior to measurement of …

Clinical Value Of Calcitonin And Carcinoembryonic Antigen Doubling Times In Medullary Thyroid Carcinoma, Charles E. Jackson, Robert A. Norum, Gary B. Talpos, Carolyn S. Feldkamp, Armen H. Tashjian Jr.

Henry Ford Hospital Medical Journal

Doubling times of basal and stimulated calcitonin (CT) levels and of random carcinoembryonic antigen (CEA) levels were compared over time in 11 patients with residual medullary thyroid carcinoma (MTC)—five with the sporadic MTC and six with the hereditary MTC. Four patients with an indolent form of the disease showed little change in CT levels over three to eight years and little change in CEA doubling times (42 to 70+ months). Seven patients showing rapid progression of disease had CT doubling times of three to 11 months and CEA doubling times of two to 12 months (however, one patient showed no …

Importance Of Ultrasound Examination For The Follow-Up Of Medullary Thyroid Carcinoma: Comparison With Other Localization Methods, Karin Frank, Friedhelm Raue, Dorothea Lorenz, Christian Herfarth, Reinhard Ziegler

Henry Ford Hospital Medical Journal

Ultrasound examinations for the follow-up of 41 patients with histologically proven medullary thyroid carcinoma (MTC) were done regularly at three- to six-month intervals. In patients with elevated serum calcitonin (CT) levels, other localization methods such as computed tomography, selective venous catheterization with measurement of CT levels, and fine-needle aspiration were performed. Thirty-four tumor recurrences in the neck were suspected by ultrasound examination in 23 patients with postoperatively elevated CT levels. The smallest occult MTC nodule had a diameter of 8 mm. One nodule was hyperechogenic with hypoechoic lesions, one was isoechoic with a halo, and all others were hypoechoic. Seventeen …

Radionuclide Imaging In Medullary Thyroid Carcinoma: Evaluation Of Two New Radiopharmaceuticals, S. E. M. Clarke, C. R. Lazarus, M. N. Maisey

Henry Ford Hospital Medical Journal

We assessed the uptake of two new radiopharmaceuticals, 131I meta-iodo-benzylguanidine (MIBG) and 99mTc(V) dimercaptosuccinic acid (DMSA), in patients with histologically proven medullary thyroid carcinoma (MTC). MIBG detected tumor in 40% of patients with known primary or recurrent tumor. 99m Tc(V) DMSA successfully demonstrated primary and recurrent tumor in 86% of patients imaged, with true negative results in 100% of patients imaged after successful surgical resection and a false-negative rate of 14%. We therefore suggest that 99m Tc(V) DMSA is the imaging agent of choice in patients with both primary and recurrent disease. 131I MIBG, with its high false-negative rate, has …

A Two-Site Immunoradiometric Assay For Serum Calcitonin Using Monoclonal Anti-Peptide Antibodies, Philippe Motte, Malika Ait-Abdellah, Pascal Vauzelle, Paule Gardet, Claude Bohuon, Dominique Bellet

Henry Ford Hospital Medical Journal

We have produced a library of monoclonal antibodies of various affinities by immunizing mice with synthetic calcitonin (CT) 1-32. These monoclonal antibodies defined two antigenic determinants on the molecule of CT. The first was located in the 11-17 region of the hormone: the second was present on the 26-32 portion of CT. The C-terminal epitope was restricted to the mature form of the hormone and immunologically silent on synthetic peptides with sequences analogous lo the biosynthetic precursors for CT. Using two high-affinity monoclonal antibodies, designated as CT07 and CT08, we developed a two-site immunoradiometric assay (m-lRMA) for serum CT. This …

In Vitro Secretion Of Peptides Of The Calcitonin Family: Calcitonin, Katacalcin, And Calcitonin Gene-Related Peptide, Friedhelm Raue, Hubert Serve, Eckard Rix, Reinhard Ziegler

Henry Ford Hospital Medical Journal

A tissue culture explant and a primary cell culture of malignant C-cells have been estabUshed to study the secretion pattern of calcitonin (CT), katacalcin (KC), and CT gene-related peptide (CGRP) in vitro under different conditions. Within the first five days of culture the spontaneous secretion of the peptides in both systems dropped to and remained at a constant level. With increasing calcium (Ca) concentration in the medium, a dose dependent release of CT, KC and, in cell culture, of CGRP was observed. BAY-K-8644. an analog of the Ca channel blocker nifedipine, enhanced the CT secretion to the same extent as …

Localization Of A Radiolabeled Monoclonal Antibody To Calcitonin In Rat Medullary Thyroid Carcinoma Allografts, Naguib A. Samaan, Kuo-Pao Yang

Henry Ford Hospital Medical Journal

A radiolabeled anticalcitonin monoclonal antibody (MoAb) was testedfor tumor-localizing capability in WAG/Rij rats allografted with cultured medullary thyroid carcinoma cells (line 44-2). 131I-labeled anticalcitonin IgG was taken up by the tumors in a time-dependent and dose-dependent manner. Tumor tissue uptake of the injected MoAb was 0.7 to 1.3%/g of tumor tissue when tested with a dose range of 40 lo 250 μg/kg of body weight. Distribution ratios of the radiolabeled MoAb were 1.2:1 for tumor-to-blood and 2-20:1 for tumor-to-organs. In rats injected with control IgG, disiribution ratios of radioactivity were 0.4:1 for tumor-to-blood, and 0.6-2:1 for tumor-to-organs. These results suggested …

Studies Of Multiple Endocrine Neoplasia Type 2a Syndrome: Linkage Analyses And Comparison Of Constitutional And Tumor Genotypes, Hideo Tateishi, Shin-Ichiro Takai, Isamu Nishisho, Tetsuro Miki, Kazuyoshi Motomura, Makoto Okazaki, Akira Miyauchi, Tatsuro Ikeuchi, Kohtaro Yamamoto, Tatsuo Hattori, Yuichi Kumahara, Hideo Matsumoto, Tasuko Honjo, Takesada Mori

Henry Ford Hospital Medical Journal

Linkage analyses were carried out in nine Japanese kindreds with multiple endocrine neoplasia type 2A (MEN-2A) using polymorphic classical markers and DNA markers. We excluded close linkage of the MEN-2A gene (MEN2A) locus with Gm, JK, PGMl, and a DNA segment, D20S5, which is assigned to band 12 of the short arm of chromosome 20 (20p12.2). Assuming that MEN2A is recessive at the cellular level as in retinoblastoma (RB) and Wilms' tumor (WT). comparison of constitutional and tumor genotypes may be useful in the search for the MEN2A locus. When DNA samples from 12 patients with medullary thyroid carcinoma (MTC) …

Where Is The Locus For Multiple Endocrine Neoplasia Type 2a?, Nancy E. Simpson, Kenneth K. Kidd

Henry Ford Hospital Medical Journal

Attempts to map the locus of the gene (MEN2A) for the multiple endocrine neoplasia type 2A (MEN-2A) syndrome over the past II years are reviewed. Lod scores from family linkage studies of polymorphisms for 26 proteins and 64 DNA markers (restriction fragment length polymorphisms or RFLPs) were pooled from the published literature and the authors' unpublished data. The pooled data excluded 32% of the genome as possible sites for the MEN2A locus. This represents a considerable increase in the area of exclusion over that of the 6% reported at the first workshop. Linkage studies of RFLPs recognized by DNA sequences …

A Non-Human Primate Model For Studying Corticotomy-Facilitated Orthodontic Tooth Movement, R. David Rynearson

Loma Linda University Electronic Theses, Dissertations & Projects

This study was undertaken to test the hypothesis that a corticotomised tooth moves as a tooth-bone unit when under orthodontic force. A non-human primate model was designed to test the hypothesis. The non-human primate selected was Macaca fasicularis. Three adult males with erupted third molars were chosen so that extrapolation could be made to the adult human. The methods employed included the following: 1) Each animal had one treatment quadrant and one control quadrant per arch; 2) Pre-op and post-op study models were made; 3) All 2nd premolars, 2nd molars, and 3rd molars were banded; 4) A full-thickness flap …

The Determination Of Antibody Levels In Endodontic Patients Against Eleven Microorganisms Using Ifa And Elisa Techniques, William C. Payne

Loma Linda University Electronic Theses, Dissertations & Projects

Endodontic (root canal) infections are generally considered to be caused by the invasion of microorganisms which destroy pulp tissue and extend to the periapical region. No definitive study has identified a specific bacterium or group of bacteria as etiological agents. We quantitively measured antibodies present in the serum of 30 normal individuals and patients with either chronic (n = 30) or acute (n = 30) periapical lesions with the indirect fluorescent antibody (IFA) and enzyme-linked immunosorbent assay (ELISA) for IgG and IgM against 11 oral microorganisms routinely isolated from such lesions. The results were analyzed statistically. Analysis of variance of …

Histologic Host Response To Polyoxymethylene Prosthesis As A Temporomandibular Joint Condylar Replacement, Frederick R. Mathews

Loma Linda University Electronic Theses, Dissertations & Projects

Polyoxyinethylene (Delrin) is a polyacetyl homopolymer which has been used successfully in many orthopedic joint replacements. To determine histologic host response to Delrin as a temporomandibular joint condylar replacement condyles were removed from ten fully mature macaca fasicularis monkeys. The condyles were replaced with a total prosthetic Delrin condyle attached to a titanium mesh. Specimens obtained at one, two, and six months indicated total acceptance of the Delrin, remodeling of the glenoid fossa and formation of bone between the middle cranial fossa and the roof of the glenoid fossa. These findings would indicate Delrin is a viable option for condylar …

Quantitation Of Teratogenic Effects Of 5-Fluorouracil Administered To Mice In Vivo Or In Submerged Limb Culture, Theresa A. Sanders

Electronic Theses and Dissertations

This study demonstrates the use of submerged limb culture in teratologic testing. Pregnant mice were treated on day 11 of gestation (E11, plug date = E0) with 10, 20 or 40 mg of 5-fluorouracil (FU) per kg body weight. On E17, treated and untreated fetuses were examined for gross malformations and were fixed in 95% ethanol. Reduction of limb size and digital defects, including ectrodactyly (ED), syndactyly (SD), microdactyly and polydactyly were dose-dependent. In parallel studies, pregnant mice were treated on the morning of E11 and embryos were removed either 7h (E11) or 24h (E12) later for submerged limb culture. …

Adaptation Of Striped Bass To Sea Water Following Direct Transfer From Freshwater: Morphological, Biochemical, And Physiological Parameters, Judy A. King

Electronic Theses and Dissertations

There has been heightened interest in the biology of striped bass (Morone saxatilis) because of increased pollution in their native spawning grounds and because of their extensive use in landlocked sport fisheries. Their euryhalinity makes them an excellent species for osmoregulation studies. The objective of this research was to study the rate of adaptation of striped bass gills to sea water (3% salt) after direct transfer from freshwater using biochemical (ion transport enzyme levels), physiological (chloride efflux), and ultrastructural methods. Striped bass have specialized osmoregulatory cells located on the interlamellar and afferent surfaces of their gill filaments as shown by …

Comparative Study Of Elongated Chromosomes In Sheep And Goats And A Proposed Standard, Stephen H. Mensher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A cell synchronization technique was used that consistently yielded numerous elongated chromosomes, which are necessary for producing high-resolution G-banding. The prometaphase stage of contraction was determined to have the greatest utility for detailed comparative analysis and, therefore, was used in the preparation of the proposed standard high-resolution karyotypes and idiogram.

A proposed standard high-resolution G-band karyotype of the domestic sheep and goat is presented, along with a high-resolution G-band idiogram of the goat. The karyotypes presented contain considerably more bands than contemporary karyotypes and provide much greater resolution for linear differentiation. The X chromosome of the sheep is acrocentric, rather …

Short Term Temporal And Spatial Variability Of Phytoplankton In The Elizabeth River, Robert L. O'Reilly

Biological Sciences Theses & Dissertations

This study was designed to evaluate short-term temporal and spatial components of phytoplankton variability within a tidal estuarine system, in reference to natural changes in the local environment.

Multiple water samples were collected weekly from October to December 1984 at 4 stations in different branches, or sections, of the Elizabeth River. Collection of chlorophyll~ data was structured to fit an analysis of variance, while the phytoplankton species and their environmental relationships were analyzed using multivariate techniques.

Lower chlorophyll a concentrations from 0.75 to 2.87 ug/1 were characteristic of the Main Stem and Southern Branch, while higher values of 1.27 …

T-Lymphocyte Subset Studies To Monitor Patients With Aids And Aids-Related Complex, Hajime Hayashi, Eugene Mezger, Michael J. Deegan, Evelyn J. Fisher, Norman Markowitz

Henry Ford Hospital Medical Journal

Multiple specimens from 124 patients from our clinic were evaluated for T4/T8 cell ratio over three to 28 months. Twenty-nine of 30 patients with the acquired immunodeficiency syndrome (AIDS), 58 of 71 patients with AIDS-related complex (ARC), and four of 23 patients at risk showed initial T4/T8 cell ratios of less than 0.8. which either remained unchanged or decreased. Seventeen of 23 AIDS patients and two of 20 ARC patients with a consistently low ratio (0.3 or less) died during the follow-up period. This indicated that the severity of disease could be predicted by periodical T4/T8 cell ratio studies. These …

Gastrointestinal Complications Of Aids: Radiologic Findings, Marc A. Bernstein, Jeremy J. Hollerman, Peter J. Feczko

Henry Ford Hospital Medical Journal

The acquired immunodeficiency syndrome (AIDS) is a significant health problem. Patients with this disease develop unusual infections and neoplasms, many within the gastrointestinal tract. Of the 66 AIDS patients seen over a three-year period at Henry Ford Hospital, 25 patients had AIDS-related gastrointestinal disease, with one death attributed to this cause. The radiologic findings and pathologic correlation of this experience are presented.
