Intraocular Lens Implant Image Quality: The Optico-Retinal Interface, David D. Bogorad

Henry Ford Hospital Medical Journal

Improvements in intraocular lens implants during the past ten years have revolutionized cataract surgery. Both anterior and posterior chamber lenses are currently in wide use, but the optical superiority of the posterior chamber location has yet to be demonstrated. To do so, a more detailed analysis is required of visual function than is clinically routine. Also required is appreciation that the retina is an integral part of the eye's optical system because of its directional characteristics, which are known as the Stiles-Crawford effect. The optical quality of the pseudophakic eye is affected by the optics of the implant, its centration, …

Immunocytologic Methods In The Diagnosis Of Orbital Tumors, David M. Reifler, Sudha R. Kini, John S. Kennerdell, Andrew Dekker, Leslie J. Fisher

Henry Ford Hospital Medical Journal

The pathologic diagnosis was supported or confirmed in three out of four cases that had an adequate cytologic specimen. The results demonstrate that adjunctive immunocytologic techniques can be used in combination with fine-needle aspiration for a variety of orbital tumors.

Malnutrition And Length Of Stay - A Relationship?, Marvin D. Anderson, Gladys Collins, Gloria Davis, Brack A. Bivins

Henry Ford Hospital Medical Journal

The admission nutrition status of 135 consecutive general medical patients admitted to a single nursing unit was evaluated using a simple questionnaire and available laboratory studies. A statistical analysis of the data obtained indicates that prolonged length of stay may be related to admission nutritional status.

Childhood Lead Poisoning, Raj P. Warrier, Jan Waisanen, Sam R. Kottamasu, Sayeed Sultana, K. Ratnakar Kini, William L. Kestenberg, John Strauthers, Craig Foreback

Henry Ford Hospital Medical Journal

Although lead encephalopathy is rare, lead intoxication continues to be a significant problem in Detroit. Neuropsychological effects may occur even at low levels of lead. Since treatment of lead poisoning consists of a painful series of injections, it is imperative that more attention be given to the prevention of this disease. To confirm the magnitude of the problems, our experience with lead poisoning during a three-year period at Henry Ford Hospital's Pediatric Department is reviewed.

Dermatomyositis Complicated By Thrombotic Thrombocytopenic Purpura, Maria A. Sawdyk, Jeffrey Jundt

Henry Ford Hospital Medical Journal

A 65-year-old woman who had a documented history of dermatomyositis was hospitalized for evaluation of a syncopal attack. During the course of her stay, she experienced progressive neurologic dysfunction, hemolytic anemia, and thrombocytopenia. A clinical diagnosis of thrombotic thrombocytopenia purpura (TTP) was made, and therapy was initiated with glucocorticoids, plasmapheresis, plasma infusion, and antiplatelet medication. The pathogenesis of TTP has not been cleady elucidated. However, reports in the literature have postulated immune damage of the endothelium with demonstration of IgM and complement deposits as the origin of the condition. Further, there are reported cases of TTP associated with collagen disorders …

Hereditary Sclerocornea, David Barsky, Steven P. Dunn

Henry Ford Hospital Medical Journal

A rare case of total hereditary sclerocornea is presented along with clinical history, histopathology, and a review of the possible pathogenesis and current literature on the subject. It is quite possible that imperfect cleavage of the anterior chamber angle may be the predisposing factor in scleralization of the cornea due to a failure of neural crest cell differentiation. If surgical intervention to correct for the corneal opacification is indicated, corneal transplantation should be performed as soon as possible after birth, similar to the indications for removal of dense congenital cataracts to avoid deprivation amblyopia.

Orbital Metastasis With Enophthalmos: A Review Of The Literature, David M. Reifler

Henry Ford Hospital Medical Journal

Orbital metastasis is associated with enophthalmos in up to one third of all cases. After analyzing the clinical and pathologic features In 25 reported cases of enophthalmic orbital metastasis, the condition was found to almost exclusively affect females, usually in the 60 to 70 age group. The right orbit was the most commonly affected. The primary lesion was located in the breast in 19 (76%) cases and in the abdomen in 6 (24%) cases. In one third of the cases, the manifestations of the orbital metastasis were recognized before diagnosing the primary lesion. The most common presenting features were diplopia …

The Pseudo-Leukocyte-Specific/Nuclear Membrane Antinuclear Antibody Pattern: A Puzzle, Thomas K. Burnham

Henry Ford Hospital Medical Journal

We report an antinuclear antibody (ANA) pattern—the pseudo-leukocyte-specific/nuclear membrane (PLS/NM) ANA pattern—that is puzzling because it usually reacts with only a few cells on human spleen imprints but with most epidermal and numerous dermal nuclei of normal human skin sections. The designation "pseudo-leukocyte-specific" was chosen because it is generally seen in only a few nuclei on human spleen imprints, thereby resembling the true leukocyte-specific ANA pattern. A few small round nuclei fluoresce homogeneously, surrounded by a bright wall, suggesting nuclear membrane (NM) fluorescence. The term "nuclear membrane" was added to the name because the NM appearance is even more prominent …

Evaluation Of Peutz-Jeghers Syndrome In A Family, Kayhan Ozkan

Henry Ford Hospital Medical Journal

Five cases of Peutz-Jeghers syndrome in one family have been studied, and a review of the history and features of the syndrome are presented. This syndrome was detected in four of six siblings and in the father. Three family members underwent surgery after small-bowel obstruction was diagnosed. A gastric polyp was removed from a fourth family member. Rectal bleeding dominated the clinical picture in two patients. Colonic polyps were also found in the three patients who had small-bowel polyps. One of the four affected siblings had mucocutaneous pigmentation, but no evidence of intestinal polyps was detected. The five affected family …

Twenty-Seven Protein Polymorphisms By Two-Dimensional Electrophoresis Of Serum, Erythrocytes, And Fibroblasts In Two Pedigrees, David Goldman, Lynn R. Goldin, P. Rathnagiri, Stephen J. O'Brien, Janice A. Egeland, Carl R. Merril

Biology Faculty Articles

Twenty-seven independent polymorphic loci were detected by two-dimensional electrophoresis (2DE) of serum, erythrocytes, and fibroblasts in two large families and analyzed for linkage to classical genetic markers. We detected seven serum, four erythrocyte, and 17 fibroblast protein loci that exhibited charge variation in these two families and in a sample of unrelated individuals. The genetic basis of protein variants was confirmed by quantitative gene-dosage dependence and by conformance to Mendelian transmission in the two families, except for four rare variants for which transmission analysis was not possible. Linkage analysis demonstrated that each of the variants represent products of independent loci, …

A Rapid Concentration And Identification Technique For Human Malaria Infections Using A Mouse Model, Donald D. Barton

Loma Linda University Electronic Theses, Dissertations & Projects

Red blood cells infected with malaria parasites experience a change in density making them lighter (less dense). This paper reports a new, rapid diagnostic technique using this change in density in the infected red blood cell. It is not only easy to use, but it is also compatible with the technological conditions found where the malaria problem is most acute - in many developing countries of the world. A small sample of blood drawn from a simple finger stick can be concentrated and examined microscopically for malaria parasites within 10 minutes. The thick film slide preparation, presently used, takes a …

The Relationship Of Vitamins B-6 And B-12 To Plasma Homocysteine Levels In Men At Low- And High-Risk For Coronary Heart Disease, Marlene E. Swift

Loma Linda University Electronic Theses, Dissertations & Projects

There is evidence that homocysteine may be a factor in increasing the risk of coronary heart disease (CHD). To explore this relationship further, we assessed the interrelation of dietary vitamins B-6, B-12 and folate, and plasma pyridoxal-5'-phosphate and vitamin B-12 with plasma free and protein-bound homocysteine levels. Fasting blood and three-day dietary records were obtained from nine men low-risk (LR) and five at high-risk (HR) for CHD. The HR mean systolic blood pressure, total cholesterol (TC), and TC/cholesterol ratios were significantly higher than LR levels. Groups were comparable by age, weight, height, skinfolds, exercise, and smoking history. No significant difference …

Soybean Oil Is Not Allergenic To Soybean-Sensitive Individuals, Robert K. Bush, Steve L. Taylor, Julie A. Nordlee, William W. Busse

Department of Food Science and Technology: Faculty Publications

We have previously demonstrated that peanut oil is not allergenic to peanut-sensitive individuals. Seven soybean-sensitive patients were enrolled in a double-blind crossover study to determine whether ingestion of soybean oil can induce adverse reactions in such patients. All subjects had histories of systemic allergic reactions (urticaria, angioedema, wheezing, dyspnea, and/or vomiting) after soybean ingestion and had positive puncture skin tests with a 1:20 w/v glycerinated-saline whole soybean extract. Sera from six of the seven subjects were tested by RAST assay for the presence of specific IgE antibodies to soybean allergens. All patients had elevated levels of serum IgE antibodies to …

High Rates Of Photosynthesis In The Desert Shrub Chrysothamnus Nauseosus Ssp. Albicaulis, Tim D. Davis, N. Sankhla, W. R. Andersen, D. J. Weber, B. N. Smith

Great Basin Naturalist

Basic aspects of photosynthesis were investigated in white rubber rabbitbrush (Chrysothamnus nauseosus (Pallas) Britt. ssp. albicaulis), a common C₃ deciduous shrub native to arid regions of the western U.S. Under favorable field conditions, net photosynthesis (P_n) ranged from 36 to 73 mg CO₂ · dm ⁻² · hr⁻¹, which is relatively high for a woody species. The leaves from the actively growing flowering shoots exhibited higher P_n than those on the vegetative shoots. P_n also varied according to the age of the leaves and the location of the plants. P …

The Distribution Of Ceratia Over The Mid-Atlantic Bight, Paul V. Zimba

Biological Sciences Theses & Dissertations

The distribution and concentration of Ceratium species, between Cape Hatteras, North Carolina and Long Island, New York ls discussed in relation to specific physical factors and the development of a phytoplankton bloom. The progression of high Ceratium counts Is discussed for the Bight areas of New York, Delaware, and the Chesapeake Bay (April through June). The concentration of Ceratium species declined after June, with highest concentrations along the New York and Delaware coast-lines. Coastal regions (less than 12 km from shore) were associated with high concentrations of several species. Path and regression analysis were used to relate physical factors and …

Enteroclysis For The Examination Of The Small Bowel, Robert D. Halpert, Peter J. Feczko, Cathrine E. Keller, Judith Iorio

Henry Ford Hospital Medical Journal

Detailed evaluation of the small bowel is difficult because of its inaccessibility. The small bowel follow-through examination using barium, has low diagnostic sensitivity. Enteroclysis, the injection of contrast material through a duodenal or jejunal tube, offers a newer and highly sensitive method of radiological evaluation. Our paper describes the technique, clinical indications, and side effects of enteroclysis.

Computed Tomographic And Sonographic Characterizations Of Central Nervous System Masses, Beatrice L. Madrazo, William P. Sanders, Bharat Mehta, Manuel Dujovny, Michael A. Sandler, David P. Chason, Jacob L. Chason, James I. Ausman

Henry Ford Hospital Medical Journal

We present our experience with 15 central nervous system masses evaluated preoperatively with computed tomography and by intraoperative sonography. Cysts were seen as sharply circumscribed, thin-walled masses, near water density by computed tomography, and echo-free by sonography. Inflammatory masses were well demarcated by tomography with areas of edema and ring enhancement but were poorly marginated and variable in appearance by sonography. Primary brain tumors presented as round, solid or complex masses best evaluated by intraoperative sonography in those cases where poor contrast enhancement resulted in limited characterization of the mass by computed tomography. Our experience suggests a very high degree …

The Tube Esophagogram In Cases Of Possible Esophageal Stricture: A Technical Note, Lawrence M. Dubin, Robert D. Halpert, Peter J. Feczko, Sambasiva R. Kottamasu

Henry Ford Hospital Medical Journal

Esophageal strictures can occasionally be underdiagnosed because of the failure to achieve complete and consistent distention of the esophagus. When tube esophagography is performed, a small catheter is positioned in the patient's esophagus, and air is insufflated after the patient drinks barium. This produces maximum, uniform distention of the esophagus with little patient discomfort. This technique is valuable in demonstrating mild or subtle strictures, improving mucosal detail, and evaluating areas suggestive of stricture on routine radiographs.

Mammography: Still The Imaging Standard, Cathrine E. Keller, A. Christine Watt

Henry Ford Hospital Medical Journal

Breast carcinoma is the leading cause of cancer death in women in the United States. Recent technological advances have resulted in multiple imaging methods designed to improve the detection of breast cancer. These imaging methods are discussed. Mammography remains the most accurate imaging method used to evaluate the breast. Automated waterpath whole-breast ultrasound is the most useful adjunctive examination to mammography at the present time.

The Incidence Of Calculi In Focal Nonshadowing Echogenicity In The Gallbladder, Michael A. Sandler, Eileen M. Biunno, Martin L. Gross, Beatrice L. Madrazo

Henry Ford Hospital Medical Journal

Sonography is valuable in the accurate diagnosis of gallstones. All but the smallest stones attenuate sound, a phenomenon known as acoustic shadowing. However, when small focal nonshadowing opacities are present, the diagnostic question is whether they represent small calculi. In a four-year review of sonographic studies performed at Henry Ford Hospital, 12 patients in whom this sonographic finding was present underwent cholecystectomies, and seven had calculi (58%). If the presence of gallstones is the factor that will determine whether surgery will be performed, we recommend a repeat examination to confirm the presence of the focal opacities and to elicit acoustic …
