Women’S Health In Developing Countries, Javed Rizvi, Nadeem F. Zuberi

Department of Obstetrics & Gynaecology

Healthcare priorities are different in developing and developed countries. A more effective resource allocation, complemented by efforts to implement only those practices that are effective, should be a priority for improving reproductive health services in developing countries. A large burden of gynaecological disease exists in developing countries and it is difficult to envisage serious reforms and improvements without an increase in public-sector spending. However, communities themselves could assume some responsibility for women's health in ways that prioritize women's own perceptions and primary needs. In this chapter we have compiled existing evidence regarding various gynaecological problems faced by women in developing …

Variability In Selecting Lateral Cephalometric Landmarks In Two Cbct Image Modes, Dana Nguyen

Loma Linda University Electronic Theses, Dissertations & Projects

Purpose: The purpose of this study was to determine the variability of lateral cephalometric landmark selection in two cone beam computed tomography (CBCT) lateral cephalometric simulations: 1) a mean projection image (MPI) and 2) a serial sagittal slice image (SSSI).

Methods: A MPI is a two-dimensional (2D) image obtained from the NewTom 3G^TM CBCT that resembles the conventional lateral cephalogram. A SSSI is a 2D image also obtained from CBCT data, but is created by superimposing a series of selected thin sagittal slices containing the required cephalometric landmarks. This study compared the Ricketts and Steiner analysis of the MPI …

An In Vitro Model Of Ovarian Cancer: Studying The Effects Of Talc And Pycnogenol®, Amber Renée Buz'zard

Loma Linda University Electronic Theses, Dissertations & Projects

Ovarian cancer is the sixth most common cancer and accounts for more deaths than any other cancer of the female reproductive system. The American Cancer Society has suggested that poor diet, talc and industrial pollutants may increase the risk of developing ovarian cancer. Talc is ubiquitous and concern is raised about its safety, role as a possible carcinogen and known ability to cause irritation and inflammation. Due to the silent nature of ovarian cancer, chemoprevention is a high priority. The most useful chemopreventive compounds will inhibit, delay or reverse carcinogenesis, and can be taken for long periods of time with …

Proteomic Identification Of In Vivo Substrates For Matrix Metalloproteinases 2 And 9 Reveals A Mechanism For Resolution Of Inflammation, Philippe Tessier

Faculty, Staff and Student Publications

Clearance of allergic inflammatory cells from the lung through matrix metalloproteinases (MMPs) is necessary to prevent lethal asphyxiation, but mechanistic insight into this essential homeostatic process is lacking. In this study, we have used a proteomics approach to determine how MMPs promote egression of lung inflammatory cells through the airway. MMP2- and MMP9-dependent cleavage of individual Th2 chemokines modulated their chemotactic activity; however, the net effect of complementing bronchoalveolar lavage fluid of allergen-challenged MMP2(-/-)/MMP9(-/-) mice with active MMP2 and MMP9 was to markedly enhance its overall chemotactic activity. In the bronchoalveolar fluid of MMP2(-/-)/MMP9(-/-) allergic mice, we identified several chemotactic …

The Sub-Axial Cervical Spine Injury Classification System (Slic): A Novel Approach To Recognize The Importance Of Morphology, Neurology And Integrity Of The Disco-Ligamentous Complex, Alexander R. Vaccaro, R. John Hulbert, Charles Fisher, Marcel Dvorak, Alpesh A. Patel, Ronald A. Lehman Jr., Paul Anderson, James Harrop, F. C. Oner, Paul Arnold, Michael Fehlings, Rune Hedlund, Ignacio Madrazo, Glenn Rechtine, Bizhan Aarabi, Mike Shainline, Spine Trauma Study Group

Department of Orthopaedic Surgery Faculty Papers

Abstract Background Context Despite technological advances in spine surgery, classification of sub-axial cervical spine injuries remains largely descriptive, lacking standardization and any relationship to prognosis or clinical decision making. Purpose The primary purpose of this paper is to define a classification system for sub-axial cervical spine trauma that conveys information about injury pattern and severity as well as treatment considerations and prognosis. The proposed system is designed to be both comprehensive and easy to use. The secondary objective is to evaluate the classification system in the basic principles of classification construction, namely reliability and validity. Study Design/Setting Derivation of the …

Cdx4 Dysregulates Hox Gene Expression And Generates Acute Myeloid Leukemia Alone And In Cooperation With Meis1a In A Murine Model, Dimple Bansal, Claudia Scholl, Stefan Frohling, Elizabeth Mcdowell, Benjamin H. Lee, Konstanze Döhner, Patricia Ernst

Dartmouth Scholarship

HOX genes have emerged as critical effectors of leukemogenesis, but the mechanisms that regulate their expression in leukemia are not well understood. Recent data suggest that the caudal homeobox transcription factors CDX1, CDX2, and CDX4, developmental regulators of HOX gene expression, may contribute to HOX gene dysregulation in leukemia. We report here that CDX4 is expressed normally in early hematopoietic progenitors and is expressed aberrantly in approximately 25% of acute myeloid leukemia (AML) patient samples. Cdx4 regulates Hox gene expression in the adult murine hematopoietic system and dysregulates Hox genes that are implicated in leukemogenesis. Furthermore, bone marrow progenitors that …

Altered Placental And Fetal Expression Of Igfs And Igf-Binding Proteins Associated With Intrauterine Growth Restriction In Fetal Sheep During Early And Mid-Pregnancy., Barbra De Vrijer, Meredith L Davidsen, Randall B Wilkening, Russell V Anthony, Timothy Regnault

Paediatrics Publications

The insulin-like growth factors (IGFs) are postulated to be altered in association with the development of intrauterine growth restriction (IUGR). The present studies examined placental and fetal hepatic mRNA concentration of components of the IGF system at two time points (55 and 90 d gestational age, dGA; Term 147 dGA) in a hyperthermia (HT)-induced sheep model of placental insufficiency-IUGR. Maternal plasma insulin and IGF-I were constant at 55 and 90 dGA and were unaffected by treatment. Umbilical vein insulin concentrations tended to be reduced at 90 dGA following HT exposure. Caruncle IGF-I mRNA was increased at 90 dGA in HT …

Bibliography Of Secondary Sources On The History Of Dermatology Iii. Books, Monographs, And Chapters In English Supplemented Through 2005., Lawrence Charles Parish, John Thorne Crissey, Jennifer L Parish, Daniel H Parish

Department of Dermatology and Cutaneous Biology Faculty Papers

Providing supplements to the history of dermatology bibliographic record has been a continuous project for the past four decades. When the endeavor was initiated, the original authors decided that only contributions in English and those directly related to dermatology, excluding sexually transmitted diseases as such, would be indexed.

There is the perennial question of whether such a manually created bibiliographic project has a need. The obvious answer remains yes. While Index Medicus has expanded the number of journals that are indexed, the number of dermatology publications currently included by Index Medicus is just over fifty. Granted, most of the papers …

Cerebral Venous Sinus Thrombosis In Neonates, Shahnaz Ibrahim

Department of Paediatrics and Child Health

Neonatal Cerebrovenous sinus thrombosis(CVST) is extremely rare, however it is a devastating condition and one needs to be aware of this condition to diagnose it. The risk factors for CVST are still not properly understood. The largest registry for stroke and for neonatal CVST is from the Canadian registry which quotes an incidence of 0.6per 100,000 population per year. No data is present for the neonatal CVST in this region.
One needs to be aware of this devastating condition to manage it timely and appropriately. To date there is no consensus on the role of anticoagulant therapy and therefore therapy …

Patient: 65-year-old female status-post liver transplant secondary to cirrhosis.

Case Description: Prior to the rehabilitation consult on post-operative day 42, she had an episode of acute rejection requiring rapid escalation of cyclosporine dosage, later changed to high dose tacrolimus for immunosuppression, resulting in high blood levels of both calcineurin inhibitors. She then complained of paroxysms of 10/10 pain over her entire body not relieved by opioids despite escalation in medication by the acute pain service. She was not participating in a rehabilitation program because of pain. Examination revealed an anxious woman for whom any tactile stimulation …

The Role Of Allograft Inflammatory Factor 1 In Systemic Sclerosis, Francesco Del Galdo, Carol M. Artlett, Sergio A. Jimenez

Selected Works of Sergio Jiménez, MD, MACR

ABSTRACT

Purpose: To review studies which support the hypothesis that allograft inflammatory factor-1 (AIF-1), a protein initially identified in chronically rejected cardiac allografts, may be involved in the pathogenesis of the progressive fibroproliferative vasculopathy which is a hallmark of systemic sclerosis (SSc).

Recent findings: Recent findings demonstrated elevated AIF-1 expression both in SSc affected tissues and peripheral blood mononuclear cells. A detailed immunohistopathologic study examined the tissue and cellular localization of the protein in affected SSc tissues and demonstrated its expression in the endothelium of dermal and pulmonary vessels, in the pulmonary parenchyma, and in relevant inflammatory cells including T …

Gnrh Agonist And Antagonist: Options For Endometriosis Pain Treatment , Frances R. Batzer

Department of Obstetrics and Gynecology Faculty Papers

Basic science research into the mechanism of the development of endometriosis, its persistence and resulting pain has begun to improve our understanding of how various therapeutic options work. While none of the available treatments resolves the underlying disease process, there are a growing number of alternatives. One of the more recent classes of medical options includes the GnRH agonist and antagonists. While at present this class of medical options is the most expensive and involved in implementation, they prove invaluable in terms of offering an aggressive, successful alternative for many patients. Furthermore, they may act directly on endometrial lesions in …

Dermatology Is A Specialty; Dermatology Is Not A Subspecialty., Lawrence Parish, Larry E Millikan

Department of Dermatology and Cutaneous Biology Faculty Papers

Specialization began in American medicine about the time of the War Between the States. Several factors spurred the direction of practitioners away from being the so-called “complete physicians. Most important were the advances in instrumentation made by the 1860’s, which allowed ophthalmology and otolaryngology to develop into distinct divisions of allopathic medicine; sometimes, they even joined together, viz eye, ear, nose, and throat specialist. Dermatology, too, became one of the early specialties for a myriad of reasons ranging from the obvious – visual inspection - to the mundane, viz. default – syphilis was too ugly and complicated for every physician …

Prognostic Indicators In Cerebral Venous Sinus Thrombosis, Bilal Hameed, Nadir Ali Syed

Section of Neurology

Cerebral venous sinus thrombosis (CVT) can affect all age groups, particularly women of childbearing age. Overall prognosis for survival and functional independence is better than it was believed. Mortality usually ranges from 6-15% and transtentorial herniation is the major cause of death. Approximately 80% of patients are functionally independent in the long term. Altered mental status and cerebral haemorrhage at presentation are the strongest predictors of death and disability. Patients with CVT related to pregnancy and puerperium generally do better than patients with other causes. Septic CVT carries a worse prognosis than aseptic CVT and of the latter, patients with …

Oral Contraceptives And Cerebral Venous Thrombosis: Case Report And A Brief Review Of Literature, Mughis Sheerani, Mian Zainul Sajadeen Urfy

Section of Neurology

Cerebral venous thrombosis remains an important and sometimes an elusive cause of strokes. Oral contraceptives seem to have a strong causative association with this entity. We describe a case that highlights the importance of asking specific questions about oral contraceptive use in patients with strokes due to cerebral venous sinus thrombosis, especially, where the cause remains cryptic.

Local Thrombolytic Treatment Of Cerebral Venous Thrombosis In Three Paediatric Patients, Mohammad Wasay, Rohit Bakshi, Alper Dai, Steve Roach

Section of Neurology

There is increasing evidence that local thrombolysis can be used with relative safety and efficacy in adults with superior sagittal sinus thrombosis (SSST). However, little data is available on the use of local thrombolysis in children with SSST. We report three patients who received local thrombolysis for dural sinus thrombosis. Two patients received urokinase and one patient received urokinase followed by local TPA infusion. Recanalization was achieved in two patients.

Obstetric Cerebral Venous Thrombosis, Bhojo Khealani, Uzma U Mapari, Rozina Sikandar Sultanali

Department of Obstetrics & Gynaecology

Pregnancy and puerperium are most prevalent prothrombotic states leading to cerebral venous thrombosis. Likelihood of stroke to be of venous origin is greater in stroke associated with pregnancy compared to stroke unrelated to pregnancy. Pregnancy induces several changes in coagulation system, which persists at least during early puerperium, rendering it a prothrombotic state. Hypercoaguability worsens further after delivery as a result of volume depletion and trauma. During puerperium additional risk factors include infection and instrumental delivery or Caesarean section. The management follows general rules as for the venous thrombosis unrelated to pregnancy, however the prognosis is different.

Computed Tomographic Imaging Of Cerebral Venous Thrombosis, Mohammad Kamran Kamal

Department of Radiology

Cerebral venous thrombosis (CVT) is an entity which is not rare and can have devastating consequences if not diagnosed and treated in a timely manner. Although, the gold standard for diagnosing this entity is a catheter angiogram, magnetic resonance venography, by virtue of its non-invasiveness and detailed demonstration of the cerebral venous structures, has become the diagnostic modality of choice for this entity. However, in a resource-strapped country like Pakistan, CT scan remains the primary first (and sometimes the only) diagnostic modality used in patients with neurological problems. Therefore, it is important to recognize the signs of cerebral venous thrombosis …

Mri And Mrv In Cerebral Venous Thrombosis, Zafar Sajjad

Department of Radiology

Although Cerebral venous thrombosis is an uncommon cause of stroke among the young, it is being increasingly recognised. A prothrombotic risk factor is identified in the majority of the patients. In most instances it is seen in women in the post-partum period and those on oral contraceptives. Magnetic Resonance Imaging (MRI) has improved our ability to diagnose this condition however the variability of radiological and clinical presentation remains a challenge. MR in combination with MR venography (MRV) is the single most sensitive diagnostic technique. The MR appearance of the thrombus within the dual sinus or cortical vein is variable and …

Thrombolytic Therapy In Cerebral Venous Sinus Thrombosis., Ayeesha Kamran Kamal

Department of Medicine

The use of thrombolytic agents to rapidly lyse the clot has emerged as a therapeutic modality, in concert with interventional neuroradiologic approaches to deliver the agent locally at the site of thrombosis. There are no randomized, double blind, placebo, controlled trials to support thrombolysis as a first line therapy in patients with cerebral venous sinus thrombosis compared to standard therapy using anticoagulation with weight based dose adjusted unfractionated Heparin. Numerous case reports and a single non randomized trial have shown that it is comparatively safe and may rescue patients who are deteriorating despite anticoagulation with unfractionated Heparin. Consideration must be …

Isolated Deep Venous Thrombosis--Case Series, Literature Review And Long Term Follow Up., Ayeesha Kamran Kamal, Ahmed Itrat, Sana Shoukat, Asumal Khealani, Kamran Kamal

Department of Medicine

Cerebral Venous Sinus thrombosis may rarely be isolated to a cortical vein or to the deep venous system. When the deep venous system is involved, prognosis is generally poor. In addition, long term follow up is not reported. We conducted a retrospective review of all patients admitted to a major tertiary care center, with the diagnosis of isolated deep venous thrombosis. Two patients were identified with isolated involvement of the deep venous system, they are reviewed in detail with long term follow up. Two young South Asian women in their thirties with rapid onset of neurologic signs and symptoms are …
