False Negative Report of 18F -FDG PET/CT in a Patient with Liver Metastases due to Uveal Melanoma

Background:To report a false negative 18F-Fluorodeoxyglucose (FDG) positron emission tomography/ computed tomography (PET/CT) of liver metastasis in a patient with malignant uveal melanoma. Material and Methods:A 74-year-old man with left eye uveal melanoma and liver metastasis that was found seven months after the enucleation surgery. Results:Seven months post-enucleation surgery, ultrasonography revealed a suspicious hepatic lesion. Further investigation using magnetic resonance imaging (MRI) and PET scan was recommended. MRI with and without contrast reported mild post-contrast enhancement in the right lobe of the liver, suggestive of metastasis from the known tumor of the patient. 18F-FDG PET/CT surprisingly showed no metabolic evidence of malignancy throughout the body. Finally, the patient was scheduled for an ultrasound-guided biopsy. Pathology reported metastatic malignant melanoma. Conclusion:It is important to remember not to rely solely on PET/CT since it may report false negative results in liver metastasis

Retinal Screening of Coats Disease Using Electroretinography

Background: Coats is a retinal disorder causing dilation of blood vessels in the human retina. The present study aims to measure electroretinography (ERG) in patients suffering from Coats disease. Material and Methods: 11 (20 eyes) male patients suffering from Coats were selected for the present study. Electroretinography was measured in the patient group using the Mangoni machine. The result was compared with the 11 (22 eyes) normal population following the ERG test. SPSS version 22 was used for this purpose. Results: The case and control groups were not significantly different in age, while a significant difference was observed in Best corrected visual acuity. BCVA between the two groups. Furthermore ( 110.9±8.63 and 93.09 ± 8.04 in control and case respectively ) , the difference between the mean amplitude of ERG, b wave was statistically significant as far as patient and normal groups were concerned.    Conclusion: Coats disease damages the retina, which can be measured by the amplitude of ERG, b wave

Electrophysiological Eye Examination Changes in a Patient with Sjogren's Syndrome

AbstractSjogren's syndrome is one of the most common autoimmune diseases. It may exist as either a primary syndrome or as a secondary syndrome associated with other autoimmune diseases such as rheumatoid arthritis and systemic sclerosis. Patient with Sjogren's syndrome have certain visual system involvements with dry eye being the most common type. These patients may also exhibit certain pathological changes in their retina and visual pathway.Here we report the electrophysiological recording including visual evoked potential, electro- retinography and electrooculography findings in a patient with Sjogren's syndrome. keywords: Sjogren's Syndrome; Evoked Potentials, Visual; Electro- retinography.

Here, we report a rare type of pulp polyp in lower third molar of a 27-year-old woman that not only grow into carious cavity but also extruded in very large size that interfered with occluding of the teeth

The study students Veiws about faculty academic Advising and consulting duties in k erman university of medical sciences in second semester in 2006

Background & Objective : Consultation is an effective factor in solving students’ problems. Providing insufficient guidance and consultation may prevent achieving educational goals. This study was conducted to evaluate students’ points of view about faculty members’ performance in providing consultation and educational guidance, Kerman University of Medical Sciences . Methods: In this cross-sectional study, senior students of all fields in 6 schools of Kerman University of Medical Sciences (490 members) were asked to fill in a researcher-made questionnaire which its validity and reliability were already confirmed. Results : According to the students’ point of view, among maximum score of 4, the highest mean score belonged to “signing and controlling course selection and other forms” (3.47). This was followed by “presence of the consultant professor in announced hours” (3.19) and “speaking with students about educational rules” (3.15). The least scores were given to “analysis of educational slump”, “encouraging students to correct educational pitfalls”, and “analysis of educational improvement” (2.3, 2.35, and 2.4 accordingly). Only 20.7% of the students completely knew in what fields and how to get help from their consultant professor. 23.4 percent believed that lack of enough consultation led to their educational problems while 24.3% were not satisfied with consultation at all . Conclusion : Our findings showed that students and faculty members are not familiar with consultant professors’ duties and consultation. Probably, consultant professors don’t do their duties appropriately. To improve the quality of consultation and guidance, it is necessary to consider consultation as a scientific entity which needs education and a scientifically competent responsible .

NoSQL Data Stores In Publish/Subscribe-Based RESTful Web Services

In the era of mobile cloud computing, the consumption of virtualized software and Web-based services from super-back-end infrastructure using smartphones and tablets is gaining much research attention from both the industry and academia. Nowadays, these mobile devices generate and access multimedia data hosted in social media and other sources in order to enhance the users’ multimedia experience. However, multimedia data is unstructured which can lead to challenges with data synchronization between these mobile devices and the cloud computing back-end. The issue with data synchronization is further fueled by the fact that mobile devices can experience intermittent connectivity losses due to unstable wireless bandwidths. While previous works proposed Simple Object Access Protocol (SOAP) -based middleware for the Web services’ synchronization, this approach is not efficient in a mobile environment because the SOAP protocol is verbose. Thus, the Representational State Transfer (REST) standard has been proposed recently to model the Web services since it is lightweight. This thesis proposes a novel approach for implementing a REST-based mobile Web Service for multimedia file sharing that utilizes a channel-based publish/subscribe communication scheme to synchronize smartphone or tablet-hosted NoSQL databases with a cloud-hosted NoSQL database. This thesis evaluates the synchronicity and the scalability of a prototype system that was implemented according to this approach. Also, this thesis assesses the overhead of the middleware component of the system

Incidence and dietary risk factors of goitre in children in a rural area/ D.R.Congo

Background: Although deficiency in dietary iodine remains the main cause of endemic and sporadic goitre, naturally occurring goitrogens in foods are additional factors that play a major role in developing goitre. In this study we focused on the relationship of different potential goitrogenous food and the development of goitre in preschool children in the rural area of Bwamanda, Democratic Republic of the Congo (DRC). Objectives: First, to do a semi-systematic literature review on the incidence of goitre and the role of dietary pattern in its genesis. Second, describe the incidence of goitre in preschool children in DRC in relation to age, sex, and season. Third, examine the effects of specific food items on occurrence of goitre in these children. Methods: For the 1st objective, we used a semi- systematic method to search for relevant published articles to the topic area. We searched four online databases, three online journals, five authors and the reference lists of the identified key articles. We did a secondary analysis of the data from an original dynamic population study which was done in the rural area of Bwamanda, DRC. That study included an open cohort of 5657 children which was followed up every 3 months throughout six survey rounds, during a period of three years from 1989- 1991. All the investigations and clinical examination were done by trained doctors and interviewers at special under five clinics in the study setting. Incidence of goitre among the children who were at risk of developing goitre was calculated for 5 survey intervals. The incidence of goitre was also assessed in relation to season, sex and age of the children. For the 3rd specific objective, seven food items were selected to be investigated for their potential goitrogenic effects. The exposed group was those children who ate these foods and the unexposed group was the children who didn’t eat these foods. Age, sex, height for age Z-score (HAZ), and weight for length Z-score (WLZ) were considered as potential confounders. All selected food items and confounders were analysed using logistic regression analysis. Results: Four studies were included in the semi-systematic literature review; the conclusion was similar in all of them with iodine deficiency being the main cause of goitre in man, and cassava consumption being an important factor in addition to that. Incidence of goitre was different in each survey interval and it was higher in rainy season. The incidence of goitre increased significantly when children got older but being a male or a female was statistically unrelated. Eating cassava leaves, cassava tubers and maize played a major role in developing goitre especially in older children, while nuts reduced the risk of developing goitre in those children. Banana, fish and papaya had non-significant contributions. iv Conclusion: This study confirms that goitre incidence in children (0-5years) in a rural area in Central Africa is significantly related with age as the older children had more risk to develop goitre than the younger children, but it had no relation to gender. The incidence of goitre increased also during rainy seasons. This is the 1st longitudinal analysis showing the relationship between consumption of specific food items and the development of goitre in children (0-5 years) in a rural area in central Africa, where cassava and maize found to be important contributory factors while nuts may have a protective role in developing goitre in those children.Master of philosophy in international healthMAMD-INTHINTH39

An IoT-Based System: Big Urban Traffic Data Mining Through Airborne Pollutant Gases Analysis

Nowadays, in developing countries including Iran, the number of vehicles is increasing due to growing population. This has recently led to waste time getting stuck in traffic, take more time for daily commute, and increase accidents. So it is necessary to control traffic congestion by traffic police officers, expand paths efficiently and choose the best way for decreasing the traffic by citizens. Therefore, it is important to have the knowledge of instant traffic in each lane. Todays, many traffic organization services such as traffic police officer and urban traffic control system use traffic cameras, inductive sensors, satellite images, radar sensors, ultrasonic technology and radio-frequency identification (RFID) for urban traffic diagnosis. But this method has some problems such as inefficiency in heavy traffic influenced by condition of the air and inability to detect parallel traffic. Our method suggested in this article detects traffic congestion based on IOT containing a smart system that gives us traffic congestion by calculating the air pollution amount in that area. According to conducted experiment, the results were satisfied
