No full textMoayid Fallatah,1 Sakher Tahaineh,2 Rawan Abu Mughli,3 Seddig M Fallatah1 1College of Medicine, Umm Al-Qura University, 2Urology Department, 3Radiology Department, Security Forces Hospital, Makkah, Saudi Arabia Abstract: Retrograde ureteric stone migration is an extremely rare phenomenon with only one previously reported case in the literature. We report on a case of upward spontaneous migration of a ureteric stone in a 39-year-old male military trainer in Saudi Arabia who was diagnosed with upper left ureteric stone based on non-contrast spiral computerized tomography kidney ureter bladder (CT-KUB) scan. The plan was to treat the patient conservatively with alpha blockers and oral hydration. Two weeks after treatment started, repeated CT-KUB scan revealed an upward migration of the stone to the left renal calyx. Accordingly, we highly recommend performing a prior stone localizing imaging test to avoid unnecessary procedures or operations. Keywords: ureteric stone, upward migration, reversed peristalsis, excessive exercise
Pain knowledge and attitude survey among health-care professionals at a university hospital in Saudi Arabia
No full textBackground: There is growing awareness in the hospital setting toward pain management to decrease patients' suffering, improve postsurgical outcomes and to decrease cost.
Objective: The aim of this study was to get an overview of the knowledge and attitude among health-care professionals toward pain management in the King Fahd Hospital of the University, and the need for an educational plan to improve pain service in hospitals.
Materials and Methods: We conducted a survey over a 3-month period based on a 30-question questionnaire to test pain knowledge and attitude among nurses and physicians of different specialties, the level of education and years of experience.
Results: The results of the data showed that knowledge and attitude of pain were deficient and unsatisfactory.
Conclusion: We concluded that efforts to spread knowledge and education of proper pain management among health-care professionals are required. Further surveys involving more hospitals are warranted
Successful management of complex regional pain syndrome type 1 using single injection interscalene brachial plexus block
No full textComplex regional pain syndrome (CRPS) type 1 of the upper limb is a painful and debilitating condition. Interscalene brachial plexus block (ISB) in conjugation with other modalities was shown to be a feasible therapy with variable success. We reported a case of CRPS type 1 as diagnosed by International Association for the Study of Pain criteria in which pharmacological approaches failed to achieve adequate pain relief and even were associated with progressive dysfunction of the upper extremity. Single injection ISB, in combination with physical therapy and botulinum toxin injection, was successful to alleviate pain with functional restoration

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Multiple levels paravertebral block versus morphine patient-controlled analgesia for postoperative analgesia following breast cancer surgery with unilateral lumpectomy, and axillary lymph nodes dissection
No full textBackground: Postoperative pain after breast cancer surgery is not uncommon. Narcotic based analgesia is commonly used for postoperative pain management. However, the side-effects and complications of systemic narcotics is a significant disadvantage. Different locoregional anesthetic techniques have been tried including, single and multiple levels paravertebral block (PVB), which seems to have a significant reduction in immediate postoperative pain with fewer side-effects. The aim of this study was to compare unilateral multiple level PVB versus morphine patient-controlled analgesia (PCA) for pain relief after breast cancer surgery with unilateral lumpectomy and axillary lymph nodes dissection.
Materials and Methods: Forty patients scheduled for breast cancer surgery were randomized to receive either preoperative unilateral multiple injections PVB at five thoracic dermatomes (group P, 20 patients) or postoperative intravenous PCA with morphine (group M, 20 patients) for postoperative pain control. Numerical pain scale, mean arterial pressure, heart rate, Time to first analgesic demand, 24-h morphine consumption side-effects and length of hospital stay were recorded.
Results: PVB resulted in a significantly more postoperative analgesia, maintained hemodynamic, more significant reduction in nausea and vomiting, and shorter hospital stay compared with PCA patients.
Conclusion: Multiple levels PVB is an effective regional anesthetic technique for postoperative pain management, it provides superior analgesia with less narcotics consumption, and fewer side-effects compared with PCA morphine for patients with breast cancer who undergo unilateral lumpectomy, with axillary lymph nodes dissection
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Xanthogranulomatous Pyelonephritis: A Retrospective Study of 10 Cases and Review of the Literature
No full textWe herewith report 10 patients with xanthogranulomatous pyelonephritis (XGP) who were treated in our department between the years 1988 and 2000. The patients′ age ranged from 20 to 60 years (mean 45 years); there were seven males and three females giving a male-female ratio of 2.3:1. Sixty percent of the patients were over 50 years old. The lesion was unilateral in all cases and pyonephrosis was found in seven patients. Nine cases had associated renal stones (90%), which led to non-functioning kidney in all these cases. Two cases had associated fistulae (one uretero-colonic fistula and one reno-cutaneous fistula). One case of focal XGP was found to be associated with renal cell carcinoma while a second patient with diffuse obstructive type of XGP and renal stone had associated transitional cell carcinoma of the renal pelvis. In all patients, the urine culture was negative. Pus culture revealed Escherechia coli in four cases (40%), Salmonella Para B in one, and no organism could be grown in four other cases. One case did not have any pus. All patients were treated with nephrectomy
