Bone Absorptiometry In Metabolic Bone Disease: Baseline Values And Long-Term Treatment With Calcitriol (Post-Menopausal Osteoporosis Versus Osteomalacia), A. Caniggia, B. Frediani

Cells and Materials

Total body bone absorptiometry reveals low mineral density in both postmenopausal osteoporosis and osteomalacia patients. The method was used to investigate the effect of calcitriol administration on patients suffering from one of these conditions. In osteomalacia, the administration of calcitriol resulted in a dramatic improvement in bone mineral density (sometimes up to 50% in 12 months), indicating the rapid mineralization of previously uncalcified bone tissue as a result of the normalization of the Ca x P product. In osteoporosis a similar treatment was seen to halt the progressive decrease in bone mineral levels and sometimes resulted in minor increases in …

Optical Bone Chambers As Tools For Studying The Bone-Implant Interface: A Review, Howard Winet

Cells and Materials

Bone chamber intravital microscopy combines the control volume of in vitro models and the chemical complexity of in vivo models to optimize the study of bone physiology in situ. As an optical tool it provides a window to dynamic events at the tissue level of magnification. In particular, it allows measures of microvascular events: (1) in space by magnifying local perfused vasculature and microcirculation at any instant, and (2) in time by providing the same volume of tissue for weekly viewing of an evolving process such as bone healing. This quartz-bearing titanium screw has revealed a consistent order for …

Some Observations On The Structure Of Encrusting Biofilms Of Proteus Mirabilis On Urethral Catheters, C. Winters, D. J. Stickler, N. S. Howe, T. J. Williams, N. Wilkinson, C. J. Buckley

Cells and Materials

A physical model of the bladder has been used to study the process of urinary catheter encrustation. Techniques have been devised for the preparation of sections through these encrustations in situ on the luminal surfaces of catheters and for mapping the distribution of calcium and magnesium in the biofilms. Transmission electron microscopy on these sections showed struvite-like crystals lying in the matrix and in direct contact with the catheter surface. Calcium phosphate ("bioapatite") was distributed throughout the film and many of these amorphous particles appear to have cells at their cores. Freeze-substituted sections of biofilms also showed electron dense materials …

Restructuring The Principle Of Medical Futility, George P. Smith Ii

Scholarly Articles

This essay surveys the need for a clear and objective definition of medical futility. It is urged that once agreement is obtained for structuring operational guidelines for determining futility, a three-tier decisional structure can be developed for testing whether a given treatment falls within the scope of these guidelines.

Under the first tier, the treating physician would be given the primary responsibility for the making the determination to withhold treatment on the grounds of futility. While the physician would be under a duty not to prescribe treatment deemed futile, he would be obliged to inform the patient and his family …

A Logistic Model Of Periodic Chemotherapy, J. C. Panetta

Mathematics & Statistics Faculty Publications

A logistic differential equation with a time-varying periodic parameter is used to model the growth of cells, in particular cancer cells, in the presences of chemotherapeutic drugs. The chemotherapeutic effects are modeled by a periodic parameter that modifies the growth rate of the cell tissue. A negative growth rate represents the detrimental effects of the drugs. A simple criterion is obtained for the behavior of the chemotherapy.

The Relationship Between Diet, Activity, And Other Factors, And Postpartum Weight Change By Race, Debra J. Boardley, Roger G. Sargent, Ann L. Coker, James R. Hussey, Patricia A. Sharpe

CRVAW Faculty Journal Articles

Objective: To identify the impact of dietary intake and activity level on postpartum weight change.

Methods: White (n = 121) and black (n = 224) women, 7-12 months postpartum, participating in the Special Supplemental Feeding Program for Women, Infants, and Children were assessed for dietary intake, activity level, body weight, and other maternal characteristics.

Results: For both black and white women, the most important variables in predicting postpartum weight loss were pre-pregnancy weight, gestational weight gain, parity, and prenatal exercise. After these factors were controlled, race predicted that black women retained 6.4 lb more than white women. These results may …

Media Components Influence Viral Gene Expression Assays In Human Fetal Astrocyte Cultures, Micheline Mccarthy, Charles Wood, Larisa Fedoseyeva, Scott R. Whittemore

Nebraska Center for Virology: Faculty Publications

In vitro neurovirological studies of viral infectivity or viral gene expression may be confounded by the mulHple neural cell types and/or fibrob last contamination present in early passage cultures prepared from dissociated human central nervous system (eNS) tissue. We have developed highly enriched astrocyte cultures for neurovirological study by culturing in a serum-free defined medium, 816, supplemented with basic fibroblast growth factor (FGF-2). Subculture in this medium selects against fibroblast proliferation and favors sustained proliferation of a highly enriched glial fibrillary acidic protein (GFAP)-positive cell population. These astrocytes support productive replication of cytomegalovirus (CMV) and transient expression of transfected CMVand …

Effectiveness Of Percutaneous Nephrostomy In Reversing Obstructive Renal Failure, I Ahmed, I H. Rizvi, A Aslam, M N. Ahmed, Y A. Hussain

Department of Radiology

A retrospective analysis of 34 patients of obstructive renal failure, initially managed by percutaneous nephrostomy was performed. Pre procedure blood biochemical profile was compared with upto one week follow-up of blood chemistry. There was a decline of 71.1% and 56.08% (P-values 0.0001 and 0.0028) in the mean values of serum creatinine and blood urea nitrogen respectively at 7 days after the procedure. Improvement in blood biochemical profile was solely dependent on performance of percutaneous nephrostomy.

Loss Of The Tumor Suppressor Genes P53 And Brca1 In Prophylactic Mastectomy Cancer Patients, Garrett Griffith Losh

Presidential Scholars Theses (1990 – 2006)

More importantly, this study has shown that prophylactic mastectomy surgery is a viable and worthwhile treatment to prevent breast cancer recurrence. It is hoped that this information will increase the knowledge of breast cancer. For the same reason, this paper has attempted to explain what cancer is while describing how the genetics of a person cause or contribute to its development. Most of all, it is hoped that this paper will emphasize the severity of this disease in the United States today and tomorrow .

Cerebral Vascular Accidents And Therapeutic Treatments, Allison L. Hartman

Presidential Scholars Theses (1990 – 2006)

A cerebral vascular accident (CVA) is commonly referred to as a stroke. Stroke is the third leading cause of death and the number one cause of serious disability in the United States. Approximately 550,000 people suffer a stroke each year; 150,000 of these result in death. Each stroke is unique. After a stroke, some victims will suffer severe deficits and/or permanent disability for the remainder of their lives. Yet other victims may suffer only mild, temporary deficits and may recover completely. Currently over three million Americans are living with the effects of stroke . Most of these individuals have been …

Case Of Pelvic Relapse In A Child Suffering From Acute Lymphoblastic Leukemia, Karim Qamruddin, Sheema Hasan, Mohammad Khurshid

Department of Pathology and Laboratory Medicine

We describe here a case of an eight years old child suffering from acute lymphoblastic leukemia. She developed pelvic infiltration of leukemic cells while in bone marrow remission and receiving maintenance chemotherapy: She also developed leukemic infiltration of Central Nervous System and died of complications resulting from massive pelvic relapse. With greater number of children in bone marrow and CNS remission, the issue ofpossible greater predisposition to extramedullary relapse has been discussed. The need for greater vigilance towards pelvic surveillance has been stressed.

Diagnosis Of Genetic Defects By Chromosomal Analysis, Farooq Ghani, Siddiqua Maniac, Zahida Khilji, Mohammad Azim, Mohammad Khurshid

Department of Pathology and Laboratory Medicine

Of 901 karyotypes performed over a period of 4 years, genetic anomalies were detected in 162 cases. Down’s syndrome (trisomy 21) was the most common (168.8%) genetic disorder followed by Turner’s syndrome, Philadelphia chromosome, Klinefelter's syndrome, Edward’s syndrome (trisomy 18) and Patau’s syn­drome (trisomy 13). All the three trisomies were detected very early in life. Mean age at the time of diagnosis for Turner’s syndrome was 13.3 years, allowing a timely hormone replacement therapy to improve secondary sexual characters. Patients with Klinefelter's syndrome were diagnosed late (mean age 23.6 years), which greatly reduced their chances of an effective therapy to …

Seroprevalence Of Toxoplasma Gondii In Domestic Animals In Pakistan, M Zaki

Department of Pathology and Laboratory Medicine

The seroprevalence of Toxoplasma gondii infections among food animals in South-West Pakistan was measured by serological examination using a commercial latex agglutination test (LAT). In all 262 blood samples, from 100 cattle, 40 sheep, 58 goats and 64 chickens, were collected from the city abattoir. Titers considered diagnostically significant (> or = 1:64) were detected in 25% of cattle and 2.5% of sheep. None of the goats and chickens presented seropositivity for anti-toxoplasma antibodies. The study suggests the need for further investigations to determine the impact of these findings on the human population.

Unchanged Maladies: Current Perspectives On Old Testament Diseases, Catherine A. Marco

Emergency Medicine Faculty Publications

As a physician reading the Old Testament this year, I often find myself speculating about some of the medical conditions referred to in the Old Testament. Although many disease entities have surely changed significantly over the past several thousand years, the human anatomy remains basically unchanged, thus rendering man susceptible to the same categories of disease in any day and age.

Patellofemoral Pain In Female Ballet Dancers: Correlation With Iliotibial Band Tightness And Tibial External Rotation, John Winslow, Evangeline Yoder

Rehabilitation Sciences Faculty Publications

Review of the literature reveals that ballet dancers have a high incidence of idiopathic patellofemoral pain. Twenty-four female ballet dancers were subjects in a study of the relationship between: 1) iliotibial band (ITB) tightness and patellofemoral pain, and 2) ITB tightness and degrees of tibial external rotation used in the dance demi-plie. Dancers were initially assessed by questionnaire to determine if any had knee pain. Twelve subjects mel the study criteria for patellofemoral pain, and 12 dancers without knee pain served as controls for the study. Iliotibial band tightness was measured (Ober test), and degrees of tibial external rotation used …

Localisation Of The Gene For A Novel Form Of Charcot-Marie-Tooth Disease In An Isolated Population, Kaite Honeyman

Theses : Honours

Localising the gene for a previously undescribed autosomal recessive form of CMT involved the use of a relatively new approach to rapid genome screening based on the identification of segments which are inherited identical by descent (IBD) from common founding ancestors. It is most feasible for populations which have been founded relatively recently (say less than 25 generations) and which have remained relatively isolated either geographically or culturally. The method is not suitable for highly inbred populations, that is with first and second cousin matings, as many segments will be inherited by chance. It appears to be a suitable screening …

Effect Of Alcohol On The Postnatal Development Of Cerebellar Cortex In Rat Ii: Ultrastructural Study, Mansoor Saleh, Saadia Sayed, Entesar Saber

Haematology and Oncology, East Africa

In The present work, it was found that alcohol produced distinct changes in both Purkinje and granule cells during postnatal development. On the fifth day, the apical cones of the Purkinje cells were less developed and the cells showed an occasional somnatic spines but no somatic processes. At 21 days and adult stage these cells including their dendrites showed marked degenerative changes. The nuinber of basket cell axon synapses on Purkinje cell soma was reduced. There was also a reduction in the amount of basket fibers contributing to the pinceau around the intial seginent of the Purkinje cell axons. The …

Perceptions Of Control And Satisfaction With Hospital Birth Experiences For First-Time Mothers, Clelia Tedeschi

Theses : Honours

Satisfaction with childbirth is associated with women's future emotional wellbeing. This study examined whether first- time mother's antenatal expectations, postnatal evaluations of control during labour and delivery, and the discrepancy between expectations and evaluations were significant predictors of women's satisfaction with their childbirth experiences. The effect of medical interventions (e.g., obstetrical interventions and pain relief medication) on women's perceptions of control and satisfaction was also examined. The purposive sample of eighty first-time mothers, mean age 26 years (excluding women who had caesareans) delivered at the public hospital where they attended antenatal classes. During their fourth antenatal class women completed a …
