Pms Or Perifollicular Phase Euphoria?, Mary Guinan

School of Public Health Faculty Research

Why is it that so little is known about PMS? First of all, there is no agreement on what PMS is. If investigators are referring to different sets of symptoms, how can studies be comparable? In fact, they are not. Not only are the symptoms different, but the timing of symptoms is different, Some studies describe symptoms that occur 7 to 10 days before the onset of menses, while others include symptoms that begin 14 days before the onset of menses and continue for 7 days after onset. This definition suggests that women may have PMS-related symptoms during 21 days …

Cloning And Sequencing Of The Genes For Shiga Toxin From Shigella Dysenteriae Type 1, Nancy A. Strockbine, Matthew Jackson, Lawrence Sung, Randall Holmes, Alison D. O'Brien

United States Public Health Resources

The structural genes for Shiga toxin, designated stx A and stx B, were cloned from Shigella dysenteriae type 1 3818T, and a nucleotide sequence analysis was performed. Both stx A and stx B were present on a single transcriptional unit, with stx A preceding stx B. The molecular weight calculated for the processed A subunit was 32,225, while the molecular weight of the processed B subunit was 7,691. Comparison of the nucleotide sequences for Shiga toxin and Shiga-like toxin I (SLT-I) from Escherichia coli revealed that the genes for Shiga toxin and SLT-I were greater than 99% homologous; three nucleotide …

Conduct Disorder And Cognitive Functioning: Testing Three Causal Hypotheses, Irvin Sam Schonfeld, David Shaffer, Patricia O'Connor, Stephanie Portnoy

Publications and Research

Studied the relation between cognitive functioning, as evidenced by IQ and achievement test performance, and Diagnostic and Statistical Manual of Mental Disorders (DSM-III) categories of conduct disturbance, using data from Black adolescents who were members of collaborative perinatal project from birth to age 7 yrs. At age 17 yrs, Ss and their parents were administered a battery of instruments that included standardized psychiatric diagnostic interviews as part of a call-back study. Analyses were compatible with the hypothesis that deficiencies in cognitive functioning are causally related to adolescent conduct disorder as defined by DSM—III. Results suggest that the relation of cognitive …

Epidemiology And Health Policy Imperatives For Aids, Katherine Hill Chavigny, Sarah L. Turner, Anne K. Kibrick

New England Journal of Public Policy

The purpose of this article is to describe the statistics and epidemiological facts about the most virulent epidemic of our age, acquired immunodeficiency syndrome (AIDS). The discussion argues for broadened public policy to promote the surveillance of communities in order to enhance the effectiveness of data gathering for epidemiological reasoning, analysis, and control measures. To accomplish these goals, the essential characteristics of epidemiology are defined. The use of deductive and inductive reasoning is applied to describe and analyze known facts concerning the AIDS epidemic. Hypotheses are suggested from current amorphous and continually changing information to assist in further explanations of …

Aids In Children: An Overview Of The Medical, Epidemiological, And Public Health Problems, Ellen R. Cooper

New England Journal of Public Policy

Cases of AIDS in children under thirteen years of age have been described since 1982. Diagnosis is more difficult in children than in adults, owing to the more varied clinical presentation and the difficulty in interpretation of laboratory tests. Current diagnostic criteria of HIV infection are reviewed, as well as symptomatology, natural history, and controversies surrounding management and therapy. Without a full appreciation of the transmissibility of HIV, issues including school and day-care attendance and foster family placement remain emotionally charged. Conflicting public policies contribute to fears on the part of the general public. Because ofthe unique implications for the …

Aids And A-Bomb Disease: Facing A Special Death, Chris Glaser

New England Journal of Public Policy

In 1979 it was called "gay cancer," and it took the life of an acquaintance. Then "gay-related immune deficiency," or GRID, claimed neighbors, friends of friends, fellow activists. I began grief and death counseling with a segment of the population ordinarily concerned with life's ambitions and enjoyments: men in their twenties and thirties. Hospital visits and memorial services became more frequent.

By 1983, when it had come to be called AIDS, my own friends began to be affected. One was a man I dated in seminary, and I was devastated to learn of his illness only upon receiving a notice …

The Clinical Spectrum Of Hiv Infections: Implications For Public Policy, Kenneth H. Mayer

New England Journal of Public Policy

The term acquired immunodeficiency syndrome (AIDS) is a definition developed by the Centers for Disease Control to explain the epidemic of immunosuppression first seen in the United States among gay and bisexual men and intravenous drug users in the early 1980s. It is now known that the human immunodeficiency virus (HIV) is the necessary agent for the compromise of the immune system which results in AIDS; however, there is a wide range of manifestations associated with HIV infection. Individuals with AIDS tend to have severe opportunistic infections or malignancies, and the vast majority ofindividuals die within two years after the …

Aids: An Overview, Loretta Mclaughlin

New England Journal of Public Policy

"We stand nakedly in front of a very serious pandemic, as mortal as any pandemic there ever has been," said Halfdan Mahler, director-general of the World Health Organization (WHO). "I don't know of any greater killer than AIDS, not to speak of its psychological, social and economic maiming. Everything is getting worse and worse with AIDS and all of us have been underestimating it, and I in particular. We're running scared. I cannot imagine a worse health problem in this century." When asked to compare AIDS to other epidemics, such as smallpox, that have infected and killed over the course …

Aids: Prophecy And Present Reality, Victor De Gruttola, William Ira Bennett

New England Journal of Public Policy

Mathematical modeling of the AIDS epidemic can be useful for policymakers even though precise projections are not possible at this time. Models are useful in establishing ranges for current and future prevalence of HIV infection and incidence of AIDS, as well as in predicting the effect of a given intervention strategy. Most decision makers are using models implicitly when they use epidemiological information as a basis for policy; formulating a model explicitly permits examination of the underlying assumptions. By creating and testing a variety of models, an investigator can determine whether the models reflect more the underlying assumptions or the …

The Quest For An Aids Vaccine, Robert T. Schooley

New England Journal of Public Policy

More than fifty thousand cases of AIDS have been reported in the United States since the disease wasfirst described in 1981. Many times this number of people are infected with human immunodeficiency virus (HIV), which has been identified as the agent responsible for the illness. The seriousness of the disease, coupled with the relatively rapid spread of HIV, has fueled the effort for development of an effective vaccine.

Much is now known about the life cycle of the virus, and about its structural components. This information, and information about methods of transmission of the virus, form the basis for a …

The Role Of Education In Aids Prevention, George A. Lamb, Linette G. Liebling

New England Journal of Public Policy

The severity of the current AIDS epidemic, combined with the lack of successful biological interventions, necessitates an active educational program as the primary intervention strategy. Health education theories abound, but relatively little definitive application of these theories has been made to the issues involved with HIV transmission: sexual behavior and the sharing of intravenous drug apparatus. Significant behavior changes have occurred in some people, but the consistency of the behavior change may be difficult to sustain. Thus, the authors suggest that health education should be delivered repeatedly in culturally acceptable language and format, by community leaders, and through many different …

The Hiv Seropositive State And Progression To Aids: An Overview Of Factors Promoting Progression, Paul H. Black, Elinor M. Levy

New England Journal of Public Policy

We have considered factors that predispose to infection by the human immunodeficiency virus as well as the clinical consequences of infection. We have also reviewed what is known about the virological status of the asymptomatic carrier, particularly the female, and the fact that pregnancy may be a cofactor for progression of HIV disease in seropositive women. Additionally, we have discussed several other cofactors that may promote the progression of HIV infection. These include intercurrent infection, excessive use of recreational drugs and alcohol, malnutrition, and stress. With respect to stress, we have reviewed evidence indicating that certain personality factors, by buffering …

Prolonged Remission Of Cushing's Disease Following Bromocriptine Therapy, Malachi J. Mckenna, Marc Linares, Raymond C. Mellinger

Henry Ford Hospital Medical Journal

A 33-year-old woman developed hypercorticism of fulminant onset following delivery of a full-term, normal child. An ectopic hormone-producing neoplasm was excluded by extensive studies. Pituitary dependent hypercorticism of intermediate lobe origin was suggested on the basis of onset following pregnancy, failure of Cortisol suppression by high-dose dexamethasone, hyperresponsiveness of prolactin to thyrotropin-releasing hormone stimulation, and reduction in adrenocorticotropin titers following oral administration of bromocriptine. Initial remission of disease achieved with bromocriptine was followed by recurrence on discontinuation of the agent. However, complete remission which occurred following a prolonged course of bromocriptine has persisted for a total of 22 months.

Management Of Extramedullary Plasmacytomas, James A. Bonner, Jadranka Dragovic, Michael P. Abrash

Henry Ford Hospital Medical Journal

From 1965 through 1982. 12 patients with solitary, biopsy-proven extramedullary plasmacytomas (EMPs) were treated at our institution with surgery alone or biopsy followed by radiation therapy. The median age of the patients was 67 years, and the median-follow-up was 58 months. Of the seven patients who were treated by primary surgery, three developed recurrent or distant disease. Five patients underwent biopsy followed by radiation therapy, and none of their tumors progressed. Our series and a review of the literature show that occasionally EMPs will incompletely regress even after high doses of radiation (greater than 65 Gy); however, we recommend that …

T-Cell Lymphoma In Renal Transplant Recipient, Koichi Maeda, Leslie Bricker, Chan K. Ma, Michael J. Deegan

Henry Ford Hospital Medical Journal

A 35-year-old woman, who had a renal transplant flve years ago, developed malignant lymphoma of the mediastinum. The lymphoma was of lymphoblastic type and had T-cell immunophenotype. Most transplant-related lymphomas are of B-cell type. T-cell lymphoma in this setting is extremely rare, and the mechanism of development may be different from that of B-cell lymphomas.

Reactions Of Organic N-Chloramines In The Gastric Fluid Of The Rat, Kathryn E. Mazina

Chemistry & Biochemistry Theses & Dissertations

Using chlorine as a drinking water disinfectant may have potential health effects due to its reactivity with organic amino nitrogen compounds found in the stomach. Organic N-chloramines have been shown to form in the stomachs of laboratory rats. The possible reactions of N-chloramines in the stomach fluid were examined in this study using a model radiolabeled N-chloramine. ³⁶Cl-N-Chloropiperidine, was synthesized and purified to remove ³⁶Cl-chloride. Stomach fluid was obtained from Sprague-Dawley rats which had been first fasted for 24 or 48 hours and then administered 3 mL of deionized water. Different concentrations of radiolabeled chloramine were reacted with …

Plasma And Tumor Levels Of Somatostatin (Srif) And Somatostatin Immunochemistry In Medullary Thyroid Carcinoma: Apparently Discrepant Preliminary Results, B. Franc, J. A. Chayvialle, E. Modigliani, C. Calmettes, B. Caillou, N. Dutrieux-Berger, C. Houdent, M. Kujas

Henry Ford Hospital Medical Journal

Eighteen cases of medullary thyroid carcinoma (MTC) (11 hereditary) had parallel measurements of basal plasma levels of somatostatin (SRIF), levels of SRIF extracted from fresh tumor tissue (radioimmunoassay), and immunohistochemistry (peroxidase-antiperoxidase method) using an anti-SRIF antibody on paraffin sections. Immunohistochemistry disclosed some cell positivity in nine cases (50%). Plasma levels of SRIF were above normal (> 50 pg/mL expressed in terms of the 14 amino acid SRIF peptide) in only two of 12 patients. Extraction of fresh tumor tissue detected SRIF in 60% of our cases: two patients > l.200pg/mg (equivalents 14). with the other positive values ranging between 13 and …

Immunohistochemistry In Medullary Thyroid Carcinoma: Prognosis And Distinction Between Hereditary And Sporadic Tumors, B. Franc, B. Caillou, A. M. Carrier, N. Dutrieux-Berger, J. Floquet, M. Houcke, E. Justrabo, F. Lange, A. Pages, C. Rigaud, A. Schwartz, M. Viennet, M. F. Lebodic

Henry Ford Hospital Medical Journal

In this retrospective study of 68 cases of medullary thyroid carcinoma (MTC), morphological features were studied, which could be helpful in prognosis and in the distinction between hereditary and sporadic forms of the disease. Necrosis within the tumors seemed to carry a poor prognosis. Bilateral MTC. unquestionable C-cell hyperplasia, glandular or follicular pattern, and thyroglobulin-positive cells seemed to be more prevalent in hereditary forms of the disease. A smaller proportion of calcitonin-immunoreactive cells were encountered in hereditary tumors than in sporadic tumors.

Different Mechanisms Of Calcitonin, Calcitonin Gene-Related Peptide, And Somatostatin Regulation By Glucocorticoids In A Cell Culture Of Human Medullary Thyroid Carcinoma, Gilbert J. Cote, Robert F. Gagel

Henry Ford Hospital Medical Journal

We have employed the TT cell line, a model for the human medullary thyroid carcinoma cell, lo study the regulation of peptide hormone production by glucocorticoids. Complementary DNA probes were used to measure the calcitonin (CT), CT gene-related peptide (CGRP), and somatostatin (SRIF) mRNA levels. Dose-response experiments in serum-free medium showed that dexamethasone (six-day treatment) lowered somatostatin (to 1% of basal) and CGRP mRNA (to 50% of basal) and stimulated CT mRNA (threefold to thirteenfold) with a half-maximal effective concentration of 10⁻⁸ M. Time course studies for cells continuously exposed to 10⁻⁶ M dexamethasone showed a rapid (within …

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 …

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 …

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 …

Case-Control Study Of Vitamin A Intake And Colorectal Cancer In Seventh-Day Adventists, John William Morgan

Loma Linda University Electronic Theses, Dissertations & Projects

Colorectal cancer is the second most common cause of cancer deaths in Americans; producing approximately 60,000 deaths in Americans each year. Studies of high and low risk populations have suggested a dietary etiology for colorectal cancer, although investigations of specific dietary factors have produced inconsistent results.

Population based studies of California Seventh-day Adventists demonstrate dietary variety regarding factors suspected as important in the etiology of colorectal cancer. These studies document a substantially reduced mortality and incidence from colorectal cancer in Seventh-day Adventists when compared to other California Populations. Although specific reasons for this difference remain obscure, the 'Unique lifestyle and …
