Thrombolytic Therapy In Acute Pulmonary Embolism Due To Heparin-Induced Thrombocytopenia Type Ii, Azza A. Alafify, Tarig S. Al-Khuwaitir, Abdurahman M. Al-Mugheiri, Djibril M Ndao

Saudi Medical Journal

Hospitalized patients are in danger of deep venous thrombosis either due to a genetic tendency, immobilization or the underlying medical condition. Paradoxically heparin, the substance used to prevent this complication, can lead to thrombo-embolic phenomena, which can be life threatening. We report a case of heparin-induced thrombocytopenia, which caused a massive pulmonary embolism, and its management by administering a thrombolytic agent in a situation where bleeding seems inevitable.

Cardiac Echinococcosis. Echocardiographic Diagnosis With A Fatal Clinical Outcome, Hayat M. Al-Mahroos, Taysir S. Garadah, Mohamed H. Aref, Rashid A. Al-Bannay

Saudi Medical Journal

Hydatid disease HD is an endemic disease found in various regions of the world. The organs mostly affected are the liver and lung. Cardiac involvement in HD is rare. The symptoms are mainly due to the mass effect of the calcific hydatid cyst obstructing the blood or the lymphatic vessels. Other manifestations are secondary infection or cyst rupture in the involved organ. Here, we report a middle aged female patient with no history of medical illness who presented to the emergency room with an unrecordable blood pressure. Echocardiogram showed multiple calcific cysts of echinococcosis granulosa in the left ventricle cavity. …

Essential Thrombocythemia In A Child. Diagnostic And Therapeutic Dilemma, Ramyar Asghar, Elahi Behzad, Golsorkhtabar-Amiri Mohammad

Saudi Medical Journal

We report an 11-year-old child with essential thrombocythemia ET, a very rare myeloproliferative disorder among children. Essential thrombocythemia can be complicated by life-threatening thrombosis with a risk of converting into acute leukemia. Cytoreductive therapy may reduce the risk of thromboembolic complications. We usually recommend cytoreductive treatment for asymptomatic adult patients with platelet counts of more than 1.5 million/micro liter, but treatment remains obscure in children. Herein, we report the results of child with ET, treated successfully with hydroxuea.

Rare Variation Of The Celiac Trunk And Related Review, Kadir Demirtas, Nadir Gulekon, Ayla Kurkcuoglu, Alper Yildirim, Rabet Gozil

Saudi Medical Journal

In this study, we report a rare variation of the branching of the celiac trunk. During a routine abdominal dissection on a female cadaver, we found the celiac trunk to emerge from the abdominal aorta as 2 roots named hepatogastric trunk and hepatosplenic trunk. The hepatogastric trunk arises from the anterior surface of the abdominal aorta and divides into an aberrant branch to the right lobe of the liver, a branch to the right hemi diaphragm, the left hepatic and the left gastric arteries. The hepatosplenic trunk, which arises 1.5 cm below the hepatogastric trunk, gave off the common hepatic …

Hip Arthroplasty For Ochronosis, Servet Kerimoglu, Cetin Onder, Osman Aynaci, Cagatay H. Malkoc

Saudi Medical Journal

Alkaptonuria is a metabolic disorder in which homogentisic acid oxidase is absent. Therefore, homogentisic acid accumulates in cartilage and connective tissues. We can diagnose ochronotic arthropathy, a manifestation of long standing alkaptonuria, through careful radiological, physical, and laboratory examination. In this report, we describe 4 cases of ochronotic arthropathy to which we applied cementless total hip prosthesis due to severe hip involvement.

Recurrent Maturing Perineal Lipoblastoma, Hashem M. Al-Momani

Saudi Medical Journal

Lipoblastoma is a rare benign neoplasm of fetal adipose tissue that we see mostly in infants and young children less than 3 years of age. Most lipoblastomas occur on the extremities, trunk, head and neck, and various other organs have been described. We report a case of a recurrent perineal lipoblastoma in a 2.5-year-old boy, which showed maturation of the lipoblasts as compared to the primary tumor.

How To Keep Beavers From Plugging Culverts, Dale L. Nolte, Dale H. Arner, John Paulson, Jeanne C. Jones, Andy Trent

United States Department of Agriculture Wildlife Services: Staff Publications

Beaver populations increased dramatically during the last half century. Beavers and beaver dams now are found on rivers, streams, and creeks across the country. Although beavers dam streams for their own benefit, the ponds create habitats for birds, fish, and other wildlife. Unfortunately, as road engineers and maintenance crews know, beavers also plug culverts. When culverts are plugged (figure 1), roads can be washed away by flooding. Removing the beavers’ dams usually requires heavy equipment, which is costly. The U.S. Department of Agriculture (USDA) Forest Service Missoula Technology and Development Center (MTDC) was asked to investigate methods to solve the …

Review Of Johanna Oksala's Foucault On Freedom, Ladelle Mcwhorter

Philosophy Faculty Publications

Johanna Oksala has produced a provocative reading of Michel Foucault's work on the issues of freedom and resistance to normalizing oppression. Although many commentators have contended that Foucault's historicization of subjectivity leads to metaphysical determinism and eliminates the very possibility of freedom in human life, Oksala argues that his radical rethinking of both bodies and freedom largely escapes the simplistic criticisms routinely put forward since the early 1980s. She does subject Foucault's work to criticisms of her own, however. While the title of her book leads the reader to expect a tight focus on the question of freedom, much of …

Isolation And Characterization Of Hydrocarbon Degrading Bacteria From Environmental Habitats In Western New York State, Katarina Malatova

Theses

Screening of hydrocarbon degrading microorganisms isolated from three habitats in Western New York State by selective enrichment technique, resulted in the collection of 20 distinct species. All strains were cultivated in liquid media with crude oil as a sole carbon and energy source. Bacterial strains capable of degrading hydrocarbons belong to the genera Serratia marcescens, Acinetobacter baumannii and Pseudomonas sp. Carbon dioxide evolution experiments were used as the major indicator of microbial degradation of oil in biometric flasks. The measurements of CO₂ evolution rates have shown to effectively evaluate the biodegradation rates by providing significant data within …

Exploiting Self-Adaptive Posture-Based Focus Estimation For Lecture Video Editing, Feng Wang, Chong-Wah Ngo, Ting-Chuen Pong

Research Collection School Of Computing and Information Systems

Head pose plays a special role in estimating a presenter’s focuses and actions for lecture video editing. This paper presents an efficient and robust head pose estimation algorithm to cope with the new challenges arising in the content management of lecture videos. These challenges include speed requirement, low video quality, variant presenting styles and complex settings in modern classrooms. Our algorithm is based on a robust hierarchical representation of skin color clustering and a set of pose templates that are automatically trained. Contextual information is also considered to refine pose estimation. Most importantly, we propose an online learning approach to …

Mining Ontological Knowledge From Domain-Specific Text Documents, Xing Jiang, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

Traditional text mining systems employ shallow parsing techniques and focus on concept extraction and taxonomic relation extraction. This paper presents a novel system called CRCTOL for mining rich semantic knowledge in the form of ontology from domain-specific text documents. By using a full text parsing technique and incorporating both statistical and lexico-syntactic methods, the knowledge extracted by our system is more concise and contains a richer semantics compared with alternative systems. We conduct a case study wherein CRCTOL extracts ontological knowledge, specifically key concepts and semantic relations, from a terrorism domain text collection. Quantitative evaluation, by comparing with a state-of-the-art …

A Geologic Record Of Methane Consumption Associated With Methane Gas Hydrates At Blake Ridge Region (Continental Rise, Offshore Southeastern United States), Walter S. Borowski, Kathryn G. Takacs, Matthew K. Thompson

EKU Faculty and Staff Scholarship

Geochemical signals locked within sedimentary rocks are a record of earth processes. Sulfide minerals (elemental sulfur, iron monosulfides, and pyrite) are formed within marine sediments by several different geochemical processes mediated by microbes. Investigating the concentration and sulfur isotopic composition (d³⁴S) of sulfide minerals gives clues about the relative importance of these competing geochemical processes.

Marine sediments of the Blake Ridge(offshore South Carolina and Georgia) contain sulfide minerals that point to anaerobic methane oxidation (AMO) as an important diagenetic process both today and in the recent geological past (Miocene). At the present-day methane-sulfate interface, upward-diffusing methane is consumed …

On Security Notions Of Steganographic Systems, Kisik Chang, Robert H. Deng, Feng Bao, Sangjin Lee, Hyungjun Kim

Research Collection School Of Computing and Information Systems

We define the notion of pseudoprocessingness to formulate chosen-input-attack, chosen-stego-attack, and key-recovery. We then construct a efficient, provable secure steganographic algorithm against chosen-input-attack and key-recovery. So far as we know, this is the first paper dealing with those security notions.

Anonymous Dos-Resistant Access Control Protocol Using Passwords For Wireless Networks, Zhiguo Wan, Robert H. Deng, Feng Bao, Akkihebbal L. Ananda

Research Collection School Of Computing and Information Systems

Wireless networks have gained overwhelming popularity over their wired counterpart due to their great flexibility and convenience, but access control of wireless networks has been a serious problem because of the open medium. Passwords remain the most popular way for access control as well as authentication and key exchange. But existing password-based access control protocols are not satisfactory in that they do not provide DoS-resistance or anonymity. In this paper we analyze the weaknesses of an access control protocol using passwords for wireless networks in IEEE LCN 2001, and propose a different access control protocol using passwords for wireless networks. …
