Spinturnicid Mites Of Venezuela (Acarina: Spinturnicidae), C. Selby Herrin, Vernon J. Tipton

Brigham Young University Science Bulletin, Biological Series

The results of an extensive survey of spinturnicid mites of bats from Venezuela are presented in this paper. Approximately 30,000 bats were collected from a wide variety of life zones and localities. A representative sample was searched for ectoparasites. There are 3 genera of the family Spinturnicidae in Venezuela: Cameronieta, Periglischrus, and Spinturnix. Three previously described species of Cameronieta were found in the Venezuelan collection. Of the 7 species of Spinturnix previously described from the New World, 4 are reported from Venezuela. The genus Periglischrus constitutes by far the most significant segment of the Venezuelan collection. It is represented by …

Distribution And Abundance Of The Black-Billed Magpie (Pica Pica) In North America, Carl E. Bock, Larry W. Lepthien

Great Basin Naturalist

Analysis of Audubon Society Christmas bird count data and certain environmental variables shows the degree to which the Black-billed Magpie is a bird of cool arid regions in North America. The abundance and distribution of this species appear to be limited by two major climatic barriers: increasing summer temperatures in the Southwest and increasing summer humidity and precipitation on the central plains.

The Effects Of Immobility On Long Bone Remodelling In The Rhesus Monkey, Charles C. Schock, Frank R. Noyes, Michael M. Crouch, Catharina H. E. Mathews

Henry Ford Hospital Medical Journal

Using Frost's method for undecalcified bone sections, long bones of the lower extremities of ten rhesus monkeys were examined following two months' immobilization and compared with thirteen controls. A decrease in appositional rate and in the surface extent of the ossification process were noted in the immobilized animals. No typical change in resorption was noted. The immobilized animals showed a decreased cortical-total area ratio. These findings suggest that a decrease in activity affects bone by depressing functions mediated by the osteoblast without necessarily evoking an Increased remodelling response.

Sjogren's Syndrome: Relationship Between Ocular Findings And Parotid Sialograms, A. O. Carbone, C. F. Petrozzi, J. Delcarpio, J. A. Zegarra

Henry Ford Hospital Medical Journal

This study evaluates the incidence and severity of the ocular findings and its correlation with the parotid gland changes, as demonstrated by sialography, in 82 patients with Sjogren's syndrome. It is shown that the ocular component of the syndrome manifests rather autonomously with respect to the accompanying collagen disease and that there seems to be only a tentative trend towards a positive correlation between the ocular and parotid findings. Sjogren's syndrome immunologically is closer to the collagen diseases than to the so-called organ-specific autoimmune diseases.

Supportive Care Of The Leukemic Patient, Ellis J. Van Slyck

Henry Ford Hospital Medical Journal

The outlook for the patient with leukemia or lymphoma has been improved by the exponential expansion of basic scientific knowledge in physical chemistry and microbiology, added to much new clinical information based on large cooperative group studies. Most of this progress derives, not from a specific treatment for the disease, but from better understanding and use of multiple support measures. These include the availability of blood components, such as red blood cell, platelet and granulocyte concentrates, better protective isolation measures, and greater expertise in the recognition and treatment of bacterial, fungal, and viral infections in immunosuppressed patients. In addition, the …

Spontaneous Asymptomatic Pneumoperitoneum, Fernando Canavati, Thomas A. Fox Jr.

Henry Ford Hospital Medical Journal

A 65-year-old man developed a spontaneous asymptomatic pneumoperitoneum which was managed conservatively without exploratory laparotomy. However, the authors caution that repeated and careful examinations of the abdomen, observation of vital signs, and leucocyte counts must be made. Also, complete radiological examination of the gastrointestinal and respiratory tracts is necessary to eliminate a possible unrecognized lesion that might explain the origin of the spontaneous pneumoperitoneum.

Bacterial Endocarditis And Incarceration Of A Transvenous Pacemaker: Removal Under Cardiopulmonary By-Pass After Prolonged Traction Proved Ineffective, Remigio Garcia, Mehdi Hakimi-Naini

Henry Ford Hospital Medical Journal

Transvenous electrode endocardial pacing of the right ventricle is the most simple and common modality of permanent pacing at present. The incidence of endocarditis is rare. Only two patients were found in our hospital series of over 200 who had permanent transvenous pacemakers implanted. A 40-year-old housewife developed staphylococcus aureus endocarditis secondary to local wound infection in the power pack pocket, requiring removal of the infected electrode under cardiopulmonary by-pass. Prolonged traction of the retained electrode proved ineffective. The mechanism of electrode entrapment is discussed.

Congestive Cardiomyopathy As An End Stage Of Toxoplasma Myocarditis, Mohsin Alam, Wolf F. C. Duvernoy, Edward L. Quinn, Evelyn J. Fisher

Henry Ford Hospital Medical Journal

Congestive cardiomyopathy is a clinical entity which may be due to many different etiologies in addition to the primary type. The case presented defines the etiology in a 30-year-old patient as previous acute toxoplasma myocarditis. This diagnosis was corroborated by diagnostic rise of fluorescent antibody and Sabin-Feldman dye test titers and response to specific therapy. Toxoplasmosis has to be considered among the causes of congestive cardiomyopathy.

Amikacin: Clinical And Laboratory Studies, Erwin J. Haas, T. Madhavan, Evelyn J. Fisher, Frank Cox, Keith Burch, Edward L. Quinn, Richard D. Nichols

Henry Ford Hospital Medical Journal

Amikacin was evaluated in vitro against S aureus and a variety of gram negative bacilli. In concentrations of 12.5 μg/ml or less, it suppressed the growth of all organisms except 15% of Proteus mirabilis. Peak serum levels in patients, following a 7.5 mg/kg IM dose, averaged 21 μg/ml at one hour. Most of the drug appeared in the urine during the first six hours after administration. Of six patients receiving an adequate course of treatment, all but one were cured. Treatment in that patient also failed with a subsequent course of gentamicin and carbenicillin and he was cured only by …

The Bacteriology Of The Biliary Tract: A Preliminary Report., J. A. Sapala, J. L. Ponka, T. R. Neblett

Henry Ford Hospital Medical Journal

The bacterial flora of acute biliary tract disease has not been completely elucidated. The organisms identified most often were coliforms. Anaerobic culture technics were not precise enough to provide proper identification. In a 12-month study of 250 patients operated upon for inflammatory gallbladder disease, culture specimens were collected in a most strict and rigorous fashion. It was hoped that a more exact understanding of the relationship between bacteria and inflammatory biliary tract disease might be appreciated. Important technics were developed for gathering specimens, delivery to the laboratory and culturing. More meaningful results are to be expected In the future.

Depth Doses In The Region Of Overlap Of The Supraclavicular And Internal Mammary Portals In Postoperative Radiation Therapy Of Carcinoma Of The Breast, Joel E. White, Michael Reidy, Murray Boles

Henry Ford Hospital Medical Journal

Computer-generated depth-dose data was obtained for the region of overlap of the internal mammary and supraclavicular portals utilized in post-operative radiation therapy for carcinoma of the breast. A phantom arrangement was created and measurements were obtained and compared with computer-generated depth doses for this arrangement. The actual measured and computer-generated values agreed to within 3%. On the patients measured at the center of the overlap region, the dose was found to vary from 3323 rets to 2571 rets over a depth range of 2-6 cm. It is occasionally the practice to ignore small areas of overlap. The dose at the …

Henry Ford Hospital Medical Journal

Two patients are presented with EKC findings suggesting pseudo AV block Mobitz type II. Pseudo AV block was related to the presence of premature junctional or ventricular beats with concealed conduction. Response to therapy confirmed the initial diagnosis of pseudo AV block. Awareness of clinical conditions simulating type II second degree AV block is important because of the therapeutic implications and prognosis.

Utilization Of Mental Health Services For Children Relative To Social Class. A Pilot Study, H. K. Von Brauchitsch

Henry Ford Hospital Medical Journal

Two groups of children were selected from those evaluated and treated over a two-year period. The study attempted to contrast the mental health care needs and the health care delivery system of children from the uppermost classes against those of the lowest classes. Very few diagnostic discriminators were found. Prevalence of intellectual dysfunctions In the lower classes and neuroses in the upper classes did not correlate with behavior pattern of "acting out" or "acting in." Autistic psychoses were found almost exclusively among the upper classes; suicidality almost exclusively In the lower classes. Upper class children were more frequently referred by …

A Rapid Flexible Method For Determining Bile Lipids, William T. Beher, Grace J. Lin, Sofia Stradnieks

Henry Ford Hospital Medical Journal

A rapid flexible method has been developed for the quantitative determination of bile lipids In gallbladder and hepatic bile and duodenal aspirates. Quantification of bile salts involves separation of bile salt conjugates from one another and other bile lipids by thin layer chromatography. The separated salts are determined using 3-hydroxysteroid dehydrogenase and gas liquid chromatography. Cholesterol is determined in petroleum ether extracts of saponified bile by application of the Lieberman-Burchard reaction. Phospholipid phosphorus is determined in purified bile lipid extracts by oxidation followed by application of Bartlett's modification of the Fiske- SubbaRow method.

The Effect Of Insulin, Fluoride And Methyl Xanthines On The Hypothalamic-Parotid Gland Endocrine Axis, Reagan Ondler

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to determine the effect of insulin and fluoride on dentinal fluid movement (FM) in high-sucrose fed rats as mediated through the hypothalamic-parotid gland endocrine axis. In conjunction with the fluoride study, the possible involvement of cAMP was examined through the use of several methyl xanthines which are recognized as phosphodiesterase inhibitors.

Twenty-one day old, male Sprague Dawley rats were maintained on a high-sugar diet (62% sucrose) for 8-9 days at which time intravenous or arterial infusions of insulin, fluoride or the methyl xanthines were performed. Additional procedures included collecting plasma from rats which had …
