High Prevalence of Obesity in a Saudi Community K.Aljabri, MD, FRCPC, S. Bokhari, MD. A Cross Section, Single Centre Study
Abstract:
Obesity is a major public health problem worldwide. We designed this study to determine the prevalence of obesity among Saudis in the department of primary care at King Fahad Armed Forces Hospital. Cross section study of Saudis of both sexes, aged more than or equal to 12 years at the department of primary care at King Fahad Armed Forces Hospital between January 2008 and June 2009. A total of 5968 were attending the department of primary care were included in this study. There were 2269 (38.0%) male and 3699 (62.0%) female. With age, a gradual increase was seen in the Body mass index (BMI) in both males and females, up to the age of 59 years, with a decrease occurring thereafter. In the females belo...
Double-Blind Randomized Trial on the Efficacy in a Short-Time Follow-Up of the “Quick Liberatory Rotation” Maneuver in Treating Posterior Canal BPPV
Abstract:
This double-blind randomized studyevaluates the efficiency of the Quick Liberatory Rotation maneuver (QLR) in solving signs and symptoms of Posterior Canal BPPV in a short time follow-up comparing the efficiency of QLR vs. a sham maneuver (“Fake QLR”).The study was performed at an input-output tertiary center for balance disorders.From January to September 2012, 200 patients with signs and symptoms of Posterior Canal BPPV respected the inclusion criteria in the study. The diagnosis was based on observation with binocular infrared videonystagmoscopy of the paroxysmal torsional and upbeat nystagmus evoked through the Dix-Hallpike test (DHT). Patients were divided in two groups, 100 in the group treated by QLR (Group 1) and 100 in the control group treated by “Fake QLR” (Group 2). Before the treatment, they self-evaluated a Visual Analogue Score on their vertiginous complaints (V-VAS). Patients were controlled one hour after the treatment by a blinded examine...
Predictors of Averse Events After Total Laryngectomy: An Analysis of the 2005-2011 NSQIP Datasets
Abstract:
We reviewed the 2005-2011 ACS-NSQIP database to evaluate factors associated with adverse events (AE) after total laryngectomy (TL). All total laryngectomies performed from 2006 to 2011 were identified for analysis. The cohort was characterized with respect to preoperative and demographic characteristics, complications, reoperation, and mortality. 493 cases were identified. Complications of any category occurred in 189 cases (38.3%). Factors that were found to confer significant risk for medical complications were increased age (dds Ratio (OR) 1.03), prior PCI (OR 2.84), disseminated cancer (OR 2.47), chronic steroid/immunosuppresion use (OR 2.87), unintended weight loss > 10% over 6 month...
Pleomorphic Adenoma of The Nasal Septum
Abstract:
Pleomorphic adenomas are uncommon tumors of the nasal cavity. They arise from minor salivary glands, and usually originate from the nasal septum. The tumors are more common in middle-aged females. We present a series of 8 cases of intranasal pleomorphic adenomas. Seven of these tumors originated from the nasal septum, and only one of them originated from the lateral nasal wall. Histopathologic examination of the tumors showed that these tumors have higher epithelial and lower stromal components compared to pleomorphic adenomas of major salivary glands. Endoscopic resection was performed in all cases and the patients were followed up for one year. No recurrences or complications were observed in this series. Endoscopic resection is recommended as the treatment of choice because of its proven efficacy and low morbidity.
Preparation Physico-Chemical Characterization and Catalytic applications of Polymer Anchored Dimethylglyoxime Copper (II) Metal Complex
Abstract:
Oxidation of 1-Proponol, 1-butanol 1-Hexanol and benzyl alcohol using chloromethylated polystyrene (6% Cross link) DMG (Dimethylglyoxime) copper complex or Poly(S-DVB)-DMG-M Where M= Cu) as catalyst and tert.butylhydroperoxide(TBHP) as oxidant, was studied. The polymer supported Cu Complex was characterized by some physicochemical and spectroscopic methods like elemental analysis IR Scanning electron micrographs (SEM). In the oxidation of 1-propanol, 1-butanol, 1-hexanol and benzyl alcohol. It was found that Product yield of these alcohols corresponding the order 1-Butanal >1-hexanone >Benzyldehyde > 1-Propanone. Kinetic data indicates that catalyst could be recycled without significant degradation of polymer
The Potentials of Antioxidant Micronutrients in the Management of Metabolic Syndrome
Abstract:
There is increasing evidence of the prevalence manifestations of metabolic syndrome worldwide. Metabolic syndrome is a cluster of abnormalities characterized by hypertension, central obesity, insulin resistance, endothelial dysfunction, dyslipidemia and oxidative stress. All these alterations predispose individuals to type 2 diabetes and cardiovascular disease that are major contributing factors to earlier mortality among people. The investigation of food nutrients that could reverse the features of metabolic syndrome is an important aspect for dietary-based therapies that may ameliorate the burden of the disorder. Antioxidant micronutrients are of great interest due to the recent described association between obesity, cardiovascular alterations and oxidative stress. These antioxidant nutrients are also being considered in the management of metabolic syndrome due to their potential benefits on hypertension, insulin resistance and hypertriglyceridemia since grow...

Bioinformatics of Metabolomics in Diabetes Mellitus Type 2
Abstract:
Diabetes mellitus type 2 (DMT2) is a complex polygenic disorder. DMT2 is a result of insulin resistance and destruction of pancreatic β-cell or dysfunction. Therefore, glucose builds up in the bloodstream, leading to nerve damage, blindness, organ failures and sometimes death. Recently, some recently discovered genes play a key role in regulating the sensitivity to insulin. Scientists have long known that the disease often runs in families, and other genetic links. Human genetic discoveries will keep improving our knowledge about diabetes for many years to come. Varieties of prospective diabetic researches were developed to diagnose and control DMT2. Researchers spent thousands of millions of dollars to address DMT2. Pioneers of advanced biotechnology developed bioinformatics tools that changed the course of research about the role of metabolomics in DMT2. It will facilitate the identification of possible causes of DMT2 in genome studies. The present article aime...
Report of a False Positive Rapid HIV Test Due to Hepatitis A in a U.S. Army Soldier
Abstract:
A 25 year old, single, active duty soldier presented to a clinic in Afghanistan complaining of malaise, fatigue, acholic stools, and mild jaundice over a 5- to 7-day period. He had significantly elevated liver transaminase levels approaching 5000 U/L and a positive rapid human immunodeficiency (HIV) 1 antibody test. Ultimately, the patient was found to have a false positive rapid HIV-1 antibody test due to acute hepatitis A virus infection. This case report describes his evaluation and outcome, in addition to exploring possible causes of false positive HIV screening.
