Background: Reflux laryngitis has gain a lot of attention in the last three decades as a possible explanation of idiopathic laryngeal problems.Acid suppressive therapy can
be of use in both the therapeutic and the diagnostic fields.The use of Omeprazole has proved to be of benefit in the diagnosis and treatment of reflux laryngitis.The
response to 12weeks course of Omeprazole is considered by many authors to be one of the diagnostic tooles of reflux laryngitis.
Aim: Is to study the effect of Omeprazole in the treatment of laryngeal manifestations of gastro-oesophageal reflux
Patients and methods: This is a prospective study of 37 patients attending Alkadhimiyah teaching hospital,department of otolalyngology during the period from
April 2005 to April 2006,complaining of symptoms suggestive of reflux laryngitis.The chief compliant of each patient was taken as a reference for the
improvment.Complete clinical examination was done for each patient as well as videolaryngoscopy.Oesophagogastroscope was done at the department of
gastroenterology. According to the findings seen in those patients,a course of Omeprazole 20mg bid was given for 12 weeks.Re-examenation including videolaryngoscopy was done at
6thand12thweeks of treatment.Oesophagogastroscopy was repeated at 12th week of treatment.
Resultst: There was symptomatic improvement in the chief complaint and improvement in the videolaryngoscopic findings in 29patients(78.38%)at the end of
treatment course with omeprazole.
Conclusion: We found that Omeprazole is effective in producing symptomatic relief in the chief complaint in 78.38% of patients at the end of treatment course.
Support Vector Machines (SVMs) are supervised learning models used to examine data sets in order to classify or predict dependent variables. SVM is typically used for classification by determining the best hyperplane between two classes. However, working with huge datasets can lead to a number of problems, including time-consuming and inefficient solutions. This research updates the SVM by employing a stochastic gradient descent method. The new approach, the extended stochastic gradient descent SVM (ESGD-SVM), was tested on two simulation datasets. The proposed method was compared with other classification approaches such as logistic regression, naive model, K Nearest Neighbors and Random Forest. The results show that the ESGD-SVM has a

The use of a face mask is among the most efficient methods for preventing the transmission of the Covid-19 virus. Wearing the face mask alone can cut the chance of catching the virus by over 70\%. Consequently, World Health Organization (WHO) advised wearing masks in crowded places as precautionary measures. Because of the incorrect use of facial masks, illnesses have spread rapidly in some locations. To solve this challenge, we needed a reliable mask monitoring system. Numerous government entities are attempting to make wearing a face mask mandatory; this process can be facilitated by using face m
... Show MoreAlzheimer’s Disease (AD) is the most prevailing type of dementia. The prevalence of AD is estimated to be around 5% after 65 years old and is staggering 30% for more than 85 years old in developed countries. AD destroys brain cells causing people to lose their memory, mental functions and ability to continue daily activities. The findings of this study are likely to aid specialists in their decision-making process by using patients’ Magnetic Resonance Imaging (MRI) to distinguish patients with AD from Normal Control (NC). Performance evolution was applied to 346 Magnetic Resonance images from the Alzheimer's Neuroimaging Initiative (ADNI) collection. The Deep Belief Network (DBN) classifier was used to fulfill classification f
... Show MoreBackground: Alcohol remains the single most significant cause of liver disease throughout the Western world, responsible for between 40 and 80% of cases of cirrhosis in different countries. Many of the factors underlying the development of alcoholic liver injury remain unknown, and significant questions remain about the value of even very basic therapeutic strategies.
Patients and Methods: In a cross sectional study, 113 alcoholic patients with evidence of liver disease in the absence of other significant etiology attending the Gastoenterorology and Hepatology Teaching Hospital between December 2001 and December 2003 were studied for the hematological and biochemical spectrum of alcoholic liver disease in
