Surgical Management Of Multicentricity, Nipple-Areola Involvement, And Bilaterality In Breast Carcinoma, F. Samhouri, M. Block, A. Kambouris Jun 1981

Surgical Management Of Multicentricity, Nipple-Areola Involvement, And Bilaterality In Breast Carcinoma, F. Samhouri, M. Block, A. Kambouris

Henry Ford Hospital Medical Journal

During a five-year period, 457 women who underwent partial, segmental, or total mastectomy were assessed for multicentricity (31%), nipple-areola involvement (17%), and bilateral breast carcinoma (9%). These factors determined the extent of surgery performed and the possibilities for later breast reconstruction. The frequency of nipple-areola involvement in breast cancer strongly indicates the need for alternatives to their preservation for breast reconstruction. The study concludes that total mastectomy for invasive carcinoma is the preferred method of treatment for early breast cancer until further clinical trials have assessed the value of segmentectomy.

Preliminary Experience With Endoscopic Papillotomy, Bernard Schuman Jun 1981

Preliminary Experience With Endoscopic Papillotomy, Bernard Schuman

Henry Ford Hospital Medical Journal

Endoscopic papillotomy is a non-operadve technique used to manage choledocholithiasis and papillary stenosis. Considerable experience in Europe and initial results in a few medical centers in the United States indicate that it is effective and safe. Six papillotomy procedures were performed at Henry Ford Hospital without complication, and with a successful outcome in five. Endoscopic papillotomy is the procedure of choice for retained common bile duct stones less than 2 cm in diameter.

Prenatal Diagnosis Of Fetal Cystic Hygromas Associated With Generalized Lymphangiectasis, Chang Y. Lee, Beatrice L. Madrazo, Daniel L. Van Dyke, Jewel Smith Jun 1981

Prenatal Diagnosis Of Fetal Cystic Hygromas Associated With Generalized Lymphangiectasis, Chang Y. Lee, Beatrice L. Madrazo, Daniel L. Van Dyke, Jewel Smith

Henry Ford Hospital Medical Journal

Ultrasonography has made possible the prenatal diagnosis of many congenital fetal abnormalities. This report describes two cases of bilateral cystic hygromas of the neck associated with generalized lymphangiectasis that were diagnosed by ultrasound. Ultrasonic scans revealed moderate polyhydramnios: thick, edematous placenta and edematous fetus with large cystic mass occupying both sides of the neck and extending to the upper chest wall, ascites, and pleural effusion at gestational ages of 21.5 and 24 weeks, respectively. In one case, chromosomal study from amniotic fluid cell culture revealed X chromosome monosomy, often associated with lymphatic anomalies. The prenatal diagnosis was confirmed at birth: …

Dysfunction Of Mitral Ball Valve Prosthesis, M. R. S. Nair, Wolf F. C. Duvernoy, Daniel T. Anbe, Eldred G. Zobl, Agustin Arbulu Jun 1981

Dysfunction Of Mitral Ball Valve Prosthesis, M. R. S. Nair, Wolf F. C. Duvernoy, Daniel T. Anbe, Eldred G. Zobl, Agustin Arbulu

Henry Ford Hospital Medical Journal

Three case histories of patients with malfunctions of Smeloff-Cutter mitral ball valve prostheses are presented here - one underwent successful replacement. The clinical diagnosis was made by observing a marked variation in the A2OC interval and intermittent absence of the opening click. Phonocardiograms were diagnostic in all three cases. while echocardiograms and even angiograms did not uniformly diagnose prosthetic valve dysfunction. Periodic phonocardiographic evaluations may be helpful in early detection of the prosthetic valve dysfunction. Once the diagnosis is established, immediate surgical treatment is imperative to prevent sudden death.

Clinical Thermoradiotherapy, H. I. Bicher, T. S. Sandhu, F. W. Hetzel Mar 1981

Clinical Thermoradiotherapy, H. I. Bicher, T. S. Sandhu, F. W. Hetzel

Henry Ford Hospital Medical Journal

A clinical trial is currently in progress to determine the efficacy of combined fractions of hyperthermia and radiation. The protocol consists of two parts. First, four fractions of microwave-induced hyperthermia (45.0° ± 0.5°C) are applied for 1 1/2 hours to the volume encompassing the tumor, each separated by 72 hours. After a one-week rest, a second series of four fractions is administered again at 72- hour intervals. Each fraction consists of a 400 rad dose of radiation followed within 20 minutes by hyperthermia (42.5 ± 0.5°C) for 1 1/2 hours. Currently, we have treated 62 patients with 82 fields with …

Clinical Hyperthermia And Irradiation: Pilot Studies, John Fazekas, Ted Nerlinger Mar 1981

Clinical Hyperthermia And Irradiation: Pilot Studies, John Fazekas, Ted Nerlinger

Henry Ford Hospital Medical Journal

Phase / (February 1979-May 1980) of our hyperthermia pilot study involved 26 carcinoma patients who participated in two treatment protocols: 20 patients received electron beam x-ray therapy plus an average of eight hyperthermia sessions (twice weekly at 42.5°-43.5°C intralesional temperatures for 40 minutes); 17 patients were heated with a 3450 microwave MHz generator in conjunction with surface heating (circulating water bag at 45°C). AGA thermograms assessed superficial blood flow to document heating patterns and forewarned of potential overheating as manifested by superficial burns (blisters). Although our study Is nonrandomized and our patient numbers are small, we noted a complete response …

Local Hyperthermia And Radiation: A Biologically-Oriented Clinical Scheduling, G. Arcangeli, A. Cividalli Mar 1981

Local Hyperthermia And Radiation: A Biologically-Oriented Clinical Scheduling, G. Arcangeli, A. Cividalli

Henry Ford Hospital Medical Journal

In a series of animal tumor studies, heat was directly delivered into the tumor mass with an interstitial applicator. After hyperthermia (44°-45°C for 45 minutes) or radiation alone (3x10 Gy), only a slight delay in tumor growth was observed, while the combined treatment, either simultaneous or sequential (i.e., heat delivered four hours after irradiation), appeared to be the most effective. The cure rate in the two combined treatment groups was 100%, in contrast to the lack of cure in the first two groups. The simultaneous use of heat and x-ray appeared to be slightly more effective than the sequential schedule; …

Glucose Metabolism In Mouse Tumor And Liver With And Without Hyperthermia, Christian Streffer, Siegelinde Hengstebeck, Peter Tamulevicius Mar 1981

Glucose Metabolism In Mouse Tumor And Liver With And Without Hyperthermia, Christian Streffer, Siegelinde Hengstebeck, Peter Tamulevicius

Henry Ford Hospital Medical Journal

We measured levels of glycolytic metabolites in mouse tumor and liver after administering a glucose load of 6 mg/g of body weight and after hyperthermia for one hour at 43°C. Metabolites included glucose, glucose-6-phosphate, fructose-1.6-diphosphate, dihydroxyacetone-phosphate, glycerol-3-phosphate, pyruvate, and lactate, as well as acetoacetate and β-hydroxybutyrate. The combined treatment led to an increase of the lactate level and apparently enhanced glucose degradation. The redoxequilibria states were shifted to the reduced metabolites. It is possible that hypoxia was induced or enhanced, which could have significance for tumor therapy. At later periods after hyperthermia, metabolic alterations occurred that have also been observed …

Hyperthermia, F. K. Storm Mar 1981

Hyperthermia, F. K. Storm

Henry Ford Hospital Medical Journal

This report describes the history of hyperthermia and reviews current forms of treatment at both low (42°-43°C) and higher (<45°C) temperatures. Hyperthermia treatment at low temperatures includes fluid immersion and irrigation, regional perfusion with heated fluids, and electromagnetic radiofrequency waves. Low-temperature hyperthermia has also been combined with radiation therapy and with chemotherapy in recent clinical trials. At higher temperatures, we and other investigators have also had promising, preliminary results in treating tumors safely. With the specialized radiofrequency instrumentation we have developed to apply hyperthermia at any depth without preferential surface tissue heating, further clinical investigation of both superficial and deep internal solid tumors is now possible. Recent data suggest that hyperthermia may be an especially effective form of therapy for larger tumors that resist standard forms of treatment. Clinical trials are now underway to determine the most therapeutic dose/time regimen, to determine toxicity and therapeutic enhancement ratios of combined chemotherapy and x-irradiation with hyperthermia, and to evaluate any changes in the host immune system with such therapies.

Hyperthermic Perfusion 16 Years After Its First Clinical Applications, R. Cavaliere, G. Moricca, F. Di Filippo, L. Aloe, G. Monticelli, F. S. Sartori

Henry Ford Hospital Medical Journal

It is known that above-normal temperatures (42°-42.5°C) provoke selective damage to neoplastic cells. We used heated circulating blood as a method for heat transfer on patients with limb tumors. From October 1964 to December 1979, we treated a total of 198 patients with hyperthermic perfusion for melanoma of the limbs (91), osteosarcoma (57), and soft tissue sarcoma (50). For melanoma patients, the five-year survival rate, excluding Stage IV, was 60%. For patients with soft tissue sarcoma, the five-year survival rates were 53% and 56% for hyperthermic perfusion and hyperthermic antiblastic perfusion. respectively. For 29 patients with osteosarcoma, hyperthermic perfusion was …

Local Microwave Hyperthermia In Cancer Therapy: Preliminary Report, Carlos A. Perez, Walter Kopecky, Robert Baglan, D. Venkata Rao, Richard Johnson Mar 1981

Local Microwave Hyperthermia In Cancer Therapy: Preliminary Report, Carlos A. Perez, Walter Kopecky, Robert Baglan, D. Venkata Rao, Richard Johnson

Henry Ford Hospital Medical Journal

This report summarizes our preliminary experience at the Mallinckrodt Institute of Radiology treating 26 patients with metastatic tumors with hyperthermia and irradiation. Patients received 400 rad fractions given every 72 hours (twice weekly) for a total of 2400, 2800, 3200, or 4000 rad followed by hyperthermia. In addition, 18 lesions were treated according to a protocol designed by the Radiation Therapy Oncology Group (RTOG) for superficial measurable tumors to receive three doses of 500 rad followed by hyperthermia (six lesions) or irradiation alone (three doses of 600, 700, or 800 rad) every 72 hours. Hyperthermia was administered with 2450 MHz …

Microwave Hyperthermia At 2450 And 915 Megahertz Frequencies, Kenneth H. Luk Mar 1981

Microwave Hyperthermia At 2450 And 915 Megahertz Frequencies, Kenneth H. Luk

Henry Ford Hospital Medical Journal

Microwave hyperthermia at frequencies of 2450 and 915 megahertz (MHz) was used to treat superficial measurable tumors of different histopathologies at various sites. Forty-seven patients received 59 courses of treatment; they were able to tolerate temperatures up to 42.5X1. Although hyperthermia alone (40°-42.5°C) did not produce an effective response, hyperthermia and radiation together (up to 2700 rad in nine fractions over three weeks) produced complete and partial responses in three-fourths of the treatment courses. The combination of hyperthermia and chemotherapy may have great potential, but confirmation of these clinical impressions will depend on a much larger series of patient data. …

Hyperthermia Treatment Of Experimental Tumors, J. Denekamp, S. A. Hill, F. A. Stewart Mar 1981

Hyperthermia Treatment Of Experimental Tumors, J. Denekamp, S. A. Hill, F. A. Stewart

Henry Ford Hospital Medical Journal

The therapeutic advantage of combining hyperthermia with x-irradiation to treat tumors depends on whether or not it is possible to achieve greater thermal sensitization of tumors than of normal tissues. To determine such therapeutic gain factors (TGE), we assessed the response of mouse skin and seven transplantable mouse tumors to graded x-ray doses given alone or combined with moderate heat (42.5°C for 60 minutes). We constructed dose response curves for the average early skin reaction and for the induced delay in tumor regrowth to an arbitrarily chosen size. We studied the following areas: 1) the therapeutic gain of combining heat …

Allergenicity Of Various Peanut Products As Determined By Rast Inhibition, Julie A. Nordlee, Steve L. Taylor, R. T. Jones, John W. Yunginger Jan 1981

Allergenicity Of Various Peanut Products As Determined By Rast Inhibition, Julie A. Nordlee, Steve L. Taylor, R. T. Jones, John W. Yunginger

Department of Food Science and Technology: Faculty Publications

Extracts of 19 different peanut products and peanut oil were tested for their allergenicity by the radioallergosorbent test inhibition assay using a crude peanut extract from raw peanuts as the standard for comparison. Seventeen of the extracts were able to competitively inhibit the binding of serum IgE from peanut-sensitive patients with the solid-phase raw peanut extract. Peanut oil and the extract from hydrolyzed peanut protein did not inhibit binding, which suggests that these products are not allergenic. The peanut hull flour extract showed a slight ability to inhibit binding, suggesting that this product contains minor amounts of the peanut allergen.

Phleborheography: A Correlative Study With Venography, Joseph P. Elliott Jr., John H. Hageman, Ann C. Belanger, Roger F. Smith Dec 1980

Phleborheography: A Correlative Study With Venography, Joseph P. Elliott Jr., John H. Hageman, Ann C. Belanger, Roger F. Smith

Henry Ford Hospital Medical Journal

The Vascular Laboratory of Henry Ford Hospital has used the Cranley-Grass Phleborheograph (PRG) as the primary noninvasive method to determine the presence or absence of deep venous thrombosis (DVT) in the lower limbs since December 1977. In order to determine its proper role and clinical reliability, we compared the diagnostic accuracy of phleborheography with contrast venography. From December 1977 through December 1978, 483 cases (963 limbs) were successfully examined by PRG. Ofthese, 111 cases (216 limbs) also had contrast venography. The PRG was confirmed as normal in 151 out of 157 (6 false negatives). There were 53 abnormal PRCs, with …

Glucose Phosphate Isomerase Deficiency: Unusual Acute Hemolytic Crisis In A Middle-Aged Woman, Koichi Maeda, Sheikh M. Saeed, Raymond W. Monto, Ernest Beutler Dec 1980

Glucose Phosphate Isomerase Deficiency: Unusual Acute Hemolytic Crisis In A Middle-Aged Woman, Koichi Maeda, Sheikh M. Saeed, Raymond W. Monto, Ernest Beutler

Henry Ford Hospital Medical Journal

Hereditary hemolytic anemia associated with glucose phosphate isomerase (GPI) deficiency was first reported in 1967. Since then, about 30 cases have been reported in the literature; their ages ranged between 1 and 26 years. We present a case of glucose phosphate isomerase deficiency in a 56-year-old woman. Steroid therapy seemed to resolve our patient's acute stage. Since it has not been mentioned previously, further evaluation is necessary. Consideration of this deficiency may be helpful in investigating hemolytic anemia, regardless of the patient's age.

Intensity Of The Second Heart Sound: Relation Of Physical, Physiological And Anatomic Factors To Auscultatory Evaluation, Paul D. Stein, Hani Sabbah Dec 1980

Intensity Of The Second Heart Sound: Relation Of Physical, Physiological And Anatomic Factors To Auscultatory Evaluation, Paul D. Stein, Hani Sabbah

Henry Ford Hospital Medical Journal

The intensity of the heart sound depends upon: 1) the distensibility of the aortic and pulmonary valves; 2) hemodynamic factors that cause the valves to distend and vibrate; 3) viscosity of the blood and its ability to inhibit diastolic valve motion; 4) the configuration of the aorta, pulmonary artery, and ventricle and the ability of the walls of the great vessels and ventricles to absorb or reflect sound energy; and 5) the capability of sound to be transmitted to the chest wall. Recognizing how these physical, physiological, and anatomic factors interact can help us to interpret auscultation of the intensity …

A Selective Approach To Bleeding Esophageal Varices, Glyn G. Jamieson, Irwin B. Faris, John Ludbrook Dec 1980

A Selective Approach To Bleeding Esophageal Varices, Glyn G. Jamieson, Irwin B. Faris, John Ludbrook

Henry Ford Hospital Medical Journal

It is possible that the best results of treatment for bleeding esophageal varices will come when a selective approach is used. In patients bleeding acutely and in patients with poor liver function shunt operations should be avoided, and a direct attack on the varices with either sclerosant therapy, percutaneous obliteration, or staple gun gastro-esophageal transsection should be carried out. In patients who have stopped bleeding, or those in whom elective treatment is being undertaken, the best operation at present appears to be selective distal splenorenal shunt.

The Analysis Of S-Adenosylmethionine And S-Adenosylhomocysteine In Normal And Neoplastic Cells, Kathryn Elizabeth Godburn Jul 1980

The Analysis Of S-Adenosylmethionine And S-Adenosylhomocysteine In Normal And Neoplastic Cells, Kathryn Elizabeth Godburn

Chemistry & Biochemistry Theses & Dissertations

Altered patterns of methylation have been shown in both ribosomal and transfer RNA isolated from cancer cells. In contrast to the elevated activity of the methyltransferases responsible for this modification, hypomethylation appears as a general characteristic. The endogenous levels of S-adenosylmethionine and S-adenosylhomocysteine are important in relationship to their role as substrate and product of the transmethylation reaction. The levels of S-adenosylmethionine and S-adenosylhomocysteine were determined using phosphocellulose cation exchange or high pressure liquid chromatography. High voltage paper electrophoresis was used in a modified procedure to directly resolve (35s) labeled S-adenosylmethionine and S-adenosylhomocysteine in small quantities of cell …

Recurrent Klebsiella Meningitis Following Trans-Sphenoidal Hypophysectomy For Nelson's Syndrome: Chloramphenicol Resistance During Relapse, Tom Madhavan, Daria Kiani, Louis Saravolatz, Keith Burch, Raymond C. Mellinger Jun 1980

Recurrent Klebsiella Meningitis Following Trans-Sphenoidal Hypophysectomy For Nelson's Syndrome: Chloramphenicol Resistance During Relapse, Tom Madhavan, Daria Kiani, Louis Saravolatz, Keith Burch, Raymond C. Mellinger

Henry Ford Hospital Medical Journal

Three episodes of meningitis due to Klebsiella pneumoniae occurred in a young man following cerebral surgery. The patient had the features of Nelson's syndrome, and a chromophobe adenoma was removed by trans-sphenoidal resection. Intravenous chloramphenicol was effective in producing a temporary clinical response during the first episode of meningitis, but the organism became resistant to chloramphenicol during the second episode. Combined parenteral and intralumbar administration of gentamicin resulted in temporary improvement only. Subsequently, the subcutaneous cerebrospinal fluid (CSF) reservoir of Ommaya provided a safe, convenient way to administer prolonged intraventricular therapy which, combined with a definitive procedure to correct the …

Occult Cushing's Syndrome Presenting With Osteoporosis, M. Kleerekoper, Sudhaker D. Rao, B. Frame, R. D. Larocque, T. Feigelman, V. Matkovic, L. V. Avioli

Henry Ford Hospital Medical Journal

Osteoporosis is a frequent complication both of endogenous hypercortisolism and of long-term treatment with corticosteroids, but only rarely is it the major clinical feature with the more characteristic features absent or minimally present. In the two patients presented, hypercortisolism was uncovered only during routine evaluation of osteoporosis. This presentation is probably due to slow progression of the disease and is often associated with so-called black adenoma of the adrenal gland. Secondary causes should be sought in all patients with seemingly "senile" or "postmenopausal" osteoporosis.
