Contribution Of Different Scintigraphic Techniques To The Management Of Medullary Thyroid Carcinoma, Dirk Sandrock, Hans-Christian Blossey, Martina Steinroeder, Dieter L. Munz

Henry Ford Hospital Medical Journal

We compared three differenl scintigraphic techniques for the localization of neck recurrences and metastases in seven patients wiih medullary thyroid carcinoma one month to eight years after the first surgical intervention. Three successive scintigraphic studies were performed in five patients (6x3 studies) within two weeks using 201Tl chloride, 111In-labeled F(ab')2 fragments of the anticarcinoembryonic antigen (anti-CEA) monoclonal antibody (MoAb) BW 431/31. and 131I meta-iodobenzylguanidine (MIBG). Additionally, 11 studies were performed wilh the 111In-labeled MoAb fragment BW 431/31 (seven studies) or the 99mTc-labeled intact anti-CEA MoAb BW 431/26 (four studies). The gold standards for classifying scintigraphic results were biopsy, histology, surgery, …

The Role Of Radiopharmaceuticals Mibg And (V) Dmsa In The Diagnosis Of Medullary Thyroid Carcinoma, Uberta Verga, Fabrizio Muratori, Gianleone Di Sacco, Franceso Banfi, Alfonso Libroia

Henry Ford Hospital Medical Journal

The diagnostic value of 123/131I meta-iodo-benzylguanidine (MIBG) and 99mTc (V) dimercaptosuccinic acid (DMSA) was investigated in 12 patients with proven medullary thyroid carcinoma (MTC). Scintigraphic imaging with DMSA was negalive in nine of 12 patients. Scintigraphy with MIBG was positive in only one case. In proven primary or recurrent disease, DMSA sensitivity was 50% and MIBG sensitivity was 25%. Such sensitivities become much lower in subjects wilh high calcitonin (CT) levels who have had negative surgical explorations: DMSA 17% and MIBG 0%. DMSA delected tumor in 25% of the patients and MIBG in only 8%. The positivity of these scintigraphies …

Diagnostic And Therapeutic Potential Of New Radiopharmaceutical Agents In Medullary Thyroid Carcinoma, Luigi Troncone, Vittoria Rufini, Giovina De Rosa, Amerigo Testa

Henry Ford Hospital Medical Journal

Recently developed radiopharmaceuticals have been proposed for imaging medullary thyroid carcinoma (MTC) with some having therapeutic potential. This study compares the imaging results obtained with radioiodinated meta-iodo-benzylguanidine (MIBG), 99mTc (V) DMSA, and 131I F(ab')2 anti-carcinoembryonic antigen (anti-CEA) in a group of MTC patients. In 23 patients 131I MIBG imaging showed a high specificity (no false-positive results) but a less satisfactory sensitivity (50%). In 12 patients 99mTc (V) DMSA revealed a better sensitivity (77%) but a lower specificity (three false-positive results). Positive results were obtained in two of three patients studied with 131I F(ab')2 anti-CEA. These data suggest that the highly …

Dna Cytophotometric Findings In Pheochromocytoma, Barbara-Christina Padberg, Esther Garbe, Eike Achilles, Henning Dralle, Max Bressel, Soren Schroeder

Henry Ford Hospital Medical Journal

Fifty adrenalectomy specimens containing normal (n = 3), hyperplastic (n =4), or neoplastic (n = 43) medullary tissue were subjected lo quantitative measurements of DNA content. Of the 43 pheochromocytomas, 16 were neoplasms inherited in the setting of multiple endocrine neoplasia type 2A. Five of 27 sporadic pheochromocytomas followed a malignant clinical course. Follow-up data were available in 25 patients. In normal medulla and adrenomedullary hyperplasia, either diploid or euploid DNA distributions were found. In contrast, 87% (33 of 38) of the benign and all five malignant pheochromocytomas exhibited nondiploid or aneuploid DNA histograms. No differences in DNA content existed …

A Preliminary Evaluation Of Calcitonin And Pdn-21 As Tumor Markers For Lung Cancer, J. J. Body, J. C. Dumon, J. P. Sculier, G. Dabouis, H. Lacroix, P. Libert, M. Richez, G. Bureau, P. Mommen, N. Raymakers, M. Paesmans, J. Klastersky

Henry Ford Hospital Medical Journal

Immunoreactive calcitonin (ICT) can be ectopically secreted by lung cancer cells and has been proposed as a tumor marker for bronchial neoplasms. Since PDN-21 (katacalcin or the carboxyl-terminal flanking peptide of the calcitonin gene) and CT are cosecreted in normal subjects and in patients with medullary thyroid carcinoma (MTC), we sought to determine the potential utility of PDN-21 as a tumor marker for lung cancer. We measured carcinoembryonic antigen (CEA), neuronspecific enolase (NSE), iCT, and PDN-21 in 119 to 378 healthy subjects, 88 to 91 patients with benign pulmonary diseases, and 249 patients with advanced lung cancer (108 small cell …

Modulation Of Calcitonin Secretion By Modification Of Calcium Channels?, Hans Scherubl, Friedhelm Raue, Michael Hoflich, Reinhard Ziegler

Henry Ford Hospital Medical Journal

Voltage-dependent calcium channels (VDCC) regulating Ca++ influx through the cellular plasma membrane play a major role in the Ca++ -induced calcitonin (CT) secretion. Using rat C-cells (rMTC 6-23 cell line), we have studied the effect of repetitive stimulation by either Ca++ (2 mM) or glucagon (10 μM) or epinephrine (10 μM) on CT secretion. Following a Ca++ -induced initial rise, CT release declined to basal levels after about four hours despite high Ca++ ; addition of 10 μM glucagon to the "Ca++ desensitized C-cells" yielded the normal stimulatory effect of glucagon on CT release. Repetitive stimulation with glucagon showed a …

The Concentration Of Prostaglandin E2 In Periradicular Lesions, Steve N. Mcnicholas

Loma Linda University Electronic Theses, Dissertations & Projects

Prostaglandins (PG) have been implicated in pathogenesis of periapical lesions. The purpose of this study was to determine the concentrations of PGE₂ in human periapical lesions. Periapical specimens from patients with clinical signs and symptoms of chronic and acute apical periodontitis were obtained and immediately frozen in liquid nitrogen. Periradicular tissues from unerupted third molars were frozen and used as controls. The concentration of PGE₂ was determined by radioimmunoassay. Low levels of PGE₂ were found in the control tissues as compared to those detected in chronic and acute lesions. A significantly higher level of PGE₂ was …

Transforming Growth Factor-Beta Stimulation Of Lung Fibroblast Prostaglandin E2 Production., Arturo Diaz, John Varga, Sergio A. Jimenez

Department of Medicine Faculty Papers

Transforming growth factor-beta (TGF beta) stimulated the production of total protein, collagen, and fibronectin by normal human lung fibroblasts. The stimulatory response was maximal at 100 pM TGF beta and reversed toward control at higher concentrations. Inhibition of fibroblast prostaglandin (PG) synthesis enhanced TGF beta-induced stimulation of total protein, collagen, and fibronectin production and reversed the negative slope of the dose-response curve at high concentrations of TGF beta. Determination of the steady-state levels of Types I and III procollagens and fibronectin mRNAs employing specific cDNA probes demonstrated that inhibition of fibroblast PG production increased the stimulatory effect of TGF beta …

Maternal-Neonatal Serum Vitamin A Concentrations., Girish S. Shirali, D G. Oelberg, K P. Mehta

Manuscripts, Articles, Book Chapters and Other Papers

Prevention of neonatal vitamin A deficiency is related to the adequacy of maternal vitamin A stores. In this study we investigated maternal and cord serum vitamin A and retinol-binding protein (RBP) values in an Indian population including, for the first time, clinically vitamin A-deficient mothers. Twenty-eight maternal-neonatal pairs were selected from maternal cohorts of high socioeconomic status without clinical evidence of vitamin A deficiency (group I) and low socioeconomic status with conjunctival xerosis and Bitot's spots (group II). Maternal education, caloric and vitamin A intakes, weight, height, hemoglobin, and birth weight were significantly lower in group II. Serum vitamin A …

Identification And Ranking Of Stressors In Nuclear Medicine Technology, Scott R. Sechrist

Community & Environmental Health Theses & Dissertations

The purpose of this study was to identify the most significant stressors in the field of nuclear medicine technology. A sample of convenience of 25 nuclear medicine technologists was used to generate a list of 35 stressors specific to the occupation. Sixty-three randomly selected nuclear medicine technologists responded to a mailed questionnaire which asked the technologist to assess the relative stressfulness of each of the 35 items on a scale of "0 to 1000". Data from the 59 valid responses indicated that equipment malfunctions, add on exams, uncooperative physicians, lack of staff, and uncooperative patients were the most significant stressors …

Microwell Based Competitive Enzyme Immunoassay For Quantifying Serum Triiodothyronine And Thyroxine Levels, Yiwen Yang

Chemistry & Biochemistry Theses & Dissertations

A microwell based competitive enzyme immunoassay for determination of total thyroxine and triiodothyronine in human serum was developed with use of horseradish peroxidase conjugate. The assay, which can be performed in only 1.5 hours at room temperature, involves simultaneous incubation of T₃- or T₄- HRPO conjugate and serum sample in anti-T₃ or anti-T₄ gamma globulin fraction coated polystyrene microwells.

Isolation of anti-T₃ and anti-T₄ gamma globulin fractions were accomplished from whole antiserum by using DEAE-cellulose chromatograph. A carbodiimide coupling method was described to prepare the T₄- and T₃-HRPO …

Recurrent Leukemia Cutis In Acute Myeloblastic Leukemia, Reda A. Girgis, Howard Terebelo, Koichi Maeda

Henry Ford Hospital Medical Journal

We report the case of a 64-year-old female with acute myeloblastic leukemia (French-American- British classification: M2) who developed two specific cutaneous manifestations during her illness. She presented with extensive cellulitis involving the face, neck, and upper chest wall. While the cellulitis resolved with antibiotic therapy, a fungating ulcerated nodule remained on the lower lip which proved to be leukemic on biopsy. Concomitant blood and bone marrow findings were diagnostic of acute myeloblastic leukemia. The lip lesion cleared with a course of chemotherapy. An erythematous macular rash subsequently developed over the lower trunk which was thought to be an allergic reaction …

Henry Ford Hospital Medical Journal

SMS 201-995 (Sandoz Pharmaceuticals. East Hanover NJ) is a synthetic peptide analog of native somatostatin that has been used to relieve .symptoms caused by neuroendocrine tumors. Reports have described an insulin suppressive effect of SMS 201-995 that results in elevations of blood glucose. We report a patient with a metastatic small bowel carcinoid and renal failure in whom mild symptomatic hypoglycemia occurred 30 to 60 minutes after SMS 201-995 administration. No increase in insulin or decreases in glucagon. Cortisol, or catecholamines were observed during these hypoglycemic episodes. Elevated levels of growth hormone fell gradually following SMS 201-995 administration and did …

Ulceroglandular Tularemia: A Typical Case Of Relapse, Stanley D. Miller, Michael B. Snyder, Michael Kleerekoper, Colby H. Grossman

Henry Ford Hospital Medical Journal

Tularemia is an infectious disease that continues to occur sporadically and in epidemics in the United States. It is characterized as an acute febrile illness with constitutional symptoms associated with skin, glandular, respiratory, or gastrointestinal involvement. Tularemia usually can be treated effectively with streptomycin. Relapse most often occurs when patients are treated with bacteriostatic agents such as chloramphenicol or tetracycline. We present a case of ulceroglandular tularemia distinguished by its relapse after initial streptomycin/doxycycline therapy and subsequent slow response to additional streptomycin.

Orf: A Case Report, Brent W. Mohr, David Katz

Henry Ford Hospital Medical Journal

Ecthyma contagiosum (orf), a viral disease endemic to sheep and goats, can be zoonotically transmitted to humans through contact with infected animals. While the disease is common among sheep and goat herders worldwide, it comes to medical attention infrequently since it is generally a mild self-limited illness. We recently treated a healthy 36-year-old female who presented with bullous lesions on her fingers and a diffuse macular rash which had developed after antibiotic therapy for her bullae. She had been caring for her neighbor's goats which had recently been ill with "sore mouth." We discuss this case of orf and review …

Early Detection Of Hereditary Medullary Thyroid Cancer With Polymorphic Dna Probes, Steven A. Narod, Hagay Sobol, Isabelle Schuffenecker, R. Alan B. Ezekowitz, Gilbert M. Lenoir

Henry Ford Hospital Medical Journal

We have performed linkage analysis on 32 families with hereditary medullary thyroid cancer (MTC) wilh seven polymorphic DNA probes situated near the centromere of chromosome 10. Nineteen of these families were affected with multiple endocrine neoplasia type 2A (MEN 2A), and the remainder had MTC without pheochromocytoma. There were no instances of recombination between the MEN 2 A susceptibility gene and the IRBP.H4 marker. Two other probes, TBM.34 and MCK2, are also tightly linked(θ = 0.00 and θ = 0.02. respectively). Because TBM.34 and IRBP.H4/MCK2 are situated on opposite sides of the MEN 2A gene, screening with flanking DNA markers …

Genetic Mechanisms Of Neoplasia In Men 2, Charles E. Jackson, Robert A. Norum

Henry Ford Hospital Medical Journal

Several possible mechanisms for the initiation and progression of tumors in multiple endocrine neoplasia type 2 (MEN 2) merit consideration. Localization of MEN2A to the pericentromeric area of chromosome 10 indicates the site of the initial mutagenic event but does not explain the tissue specificity observed. The consistency of tissue involvement within families, despite the variability between families, suggests that the tumors result from separate but contiguous tissue-specific genes arranged in a particular linear order. Linkage studies in MEN 2A and 2B families are compatible with this contiguous gene theory. Data suggest that Knudson's two-mutational-event theory is applicable in MEN2, …
