Abstract: as a consequence of the dengue epidemic in the bolivian republic and the northern provinces of argentina, an outbreak of indigenous dengue occurred for the first time in the buenos aires metropolitan area. since january 2009 we assisted imported dengue cases coming from epidemic regions; later, around the end of march, and until middle autumn, indigenous cases appeared. the major concentration of these indigenous cases was in the west area of buenos aires city and in the neighboring localities 3 de febrero and la matanza. there were several factors that made the local transmission possible: a high vector density, people traveling from epidemic areas and clustering in the geographical zone where the indigenous epidemic occurred, during a period with high medium temperatures, entering 95% of the imported cases during the first days of the viremia. of the nine patients with alarming signs for the development of severe dengue, seven were indigenous cases with no previous history of dengue infections. we report the clinical and epidemiological findings, and we analyze the factors which regulated the transmission.

Journal of Tuberculosis Research (JTR) , 2017, DOI: 10.4236/jtr.2017.51002
Abstract: According to the World Health Organization, Tb is the biggest cause of death among the infectious diseases. Due to the high percentage of people with tuberculosis infection and the high number of death among these patients, this study is a prospective study aimed to categorize and find the relationship between different clinical and demographic characteristics. The study was conducted on 600 patients from Masih-e-Daneshvari tuberculosis research center during 2015-2016. The K-Means clustering data mining algorithms and decision trees are used to perform the categorization and determine common indicators among patients. 2 clusters according to Dunn index were chosen as the optimal clusters. Common factors between clusters are provided in detail in the findings section. According to the results of this study, the most important factors identified by the clustering include hemoglobin, age, sex, smoking, alcohol consumption and creatinine. The RBF neural network tree has 98% accuracy. According to the results of this study, the most important factors identified are sex, smoking, alcohol consumption and WBC, albumin.
Two versions of Nakayama lemma for multiplication modules

International Journal of Mathematics and Mathematical Sciences , 2004, DOI: 10.1155/s0161171204311282
Abstract: The aim of this note is to generalize the Nakayama lemma to a class of multiplication modules over commutative rings with identity. In this note, by considering the notion of multiplication modules and the product of submodules of them, we state and prove two versions of Nakayama lemma for such modules. In the first version we give some equivalent conditions for faithful finitely generated multiplication modules, and in the second version we give them for faithful multiplication modules with a minimal generating set.

International Journal of Mathematics and Mathematical Sciences , 2003, DOI: 10.1155/s0161171203202180
Abstract: By considering the notion of multiplication modules over a commutative ring with identity, first we introduce the notion product of two submodules of such modules. Then we use this notion to characterize the prime submodules of a multiplication module. Finally, we state and prove a version of Nakayama lemma for multiplication modules and find some related basic results.

Audiology , 1999,
Abstract: Introduction: We estimated the noise in an industrial shoe factory to determine the effect of noise in the workplace on the hearing status of the workers in such environments.Materials and method: the intensity of noise in dB in different parts of the factory was estimated. Then working people in each part was selected randomly and their hearing thresholds were evaluated by Conventional audiometry.Results: The results demonstrated that 23% were required to estimate thresholds more precisely and 95 needed close examination by Otolaryngologist. Besides, 10% of the workers suffered sensory neural hearing loss whose 2% of them diagnosed as NIHL.Discussion: Since the mentioned factory has good hearing conservation program for the workers, it seems that promoting the program can decline the number of noise induced hearing losses to the least numbers.

Abstract: Tuberculosis (TB) remains the most frequent cause of illness and death from an infectious agent, and its interaction with HIV has devastating effects. We determined plasma levels of dehydroepiandrosterone (DHEA), its circulating form DHEA-suphate (DHEA-s) and cortisol in different stages of M. tuberculosis infection, and explored their role on the Th1 and Treg populations during different scenarios of HIV-TB coinfection, including the immune reconstitution inflammatory syndrome (IRIS), a condition related to antiretroviral treatment. DHEA levels were diminished in HIV-TB and HIV-TB IRIS patients compared to healthy donors (HD), HIV+ individuals and HIV+ individuals with latent TB (HIV-LTB), whereas dehydroepiandrosterone sulfate (DHEA-s) levels were markedly diminished in HIV-TB IRIS individuals. HIV-TB and IRIS patients presented a cortisol/DHEA ratio significantly higher than HIV+, HIV-LTB and HD individuals. A positive correlation was observed between DHEA-s and CD4 count among HIV-TB individuals. Conversely, cortisol plasma level inversely correlated with CD4 count within HIV-TB individuals. M. tuberculosis-specific Th1 lymphocyte count was increased after culturing PBMC from HIV-TB individuals in presence of DHEA. We observed an inverse correlation between DHEA-s plasma level and Treg frequency in co-infected individuals, and CD4+FoxP3+ Treg frequency was increased in HIV-TB and IRIS patients compared to other groups. Strikingly, we observed a prominent CD4+CD25-FoxP3+ population across HIV-TB and HIV-TB IRIS patients, which frequency correlated with DHEA plasma level. Finally, DHEA treatment negatively regulated FoxP3 expression without altering Treg frequency in co-infected patients. These data suggest an enhancing role for DHEA in the immune response against M. tuberculosis during HIV-TB coinfection and IRIS.

Archivos Espa?oles de Urología (Ed. impresa) , 2009, DOI: 10.4321/S0004-06142009000800011
Abstract: objectives: retroperitoneal tumors are a rare finding and most masses are of malignant origin. we report laparoscopic management of a low grade retroperitoneal leiomyosarcoma. methods: a 56 year old woman with a left 12 cm retrorenal mass underwent transperitoneal laparoscopic exploration. the tumor was clearly visualized on the lateral aspect of the left kidney. following basic oncologic principles, the mass was carefully dissected off the renal capsule and extracted in a laparoscopic bag through a small incision on the left lower quadrant. results: operative time was 135 minutes and estimated surgical bleeding was 200 ml. the patient evolved uneventfully and was discharged home on postoperative day 3. final pathological analysis revealed that the lesion was a very low grade leiomyosarcoma. at six months follow-up the patient remains disease free and has completely recovered. conclusions: even though open surgery remains the standard treatment for all retroperitoneal tumors, the laparoscopic approach of a retroperitoneal mass is technically feasible and oncologically safe. further studies will show long term results.
Aggression in children
Daneshvar-Ameri,Z
Hayat Journal of Faculty of Nursing & Midwifery , 2003,
Abstract: Links between violence, aggression, and mental illness are well documented. Despite this association, our current understanding of the factors for and optimal treatment of aggression remains limited. This lack of knowledge is alarming because nurses, particularly pediatric nurses who treat aggressive children, are frequent targets of patient aggression. Consequently, the aim of this article is to provide information regarding the concept of aggression in child patients, assessment of violent behavior, implementation of interventional treatment and a review of medical, psychological and social strategies which assist in the understanding of aggression and its clinical intervention. However, the etiology of aggression for the most part still remains a mystery.

Abstract: This paper represents a retrospective study of 142 patients with skeletal tuberculosis during the years 1350 to 1357 at Shafa Yahiaian Hospital. Confirmation of diagnosis is made by positive culture or pathology. The mean age of the patients was 27.5 years (range from 1.5 to 72 years). Most of the patients were in the second, first and third decade respectively. 45.3% of the patients were female. The spine was the most common site and was affected in 40.88% of the patients. The next sites were knee, hip and elbow, in order of frequency. The commonest site in spine was thoracic. The mean of sedimentation rate in the first visit was 48. Tuberculin skin test was negative in 23% of the patients. Evidence of pulmonary tuberculosis in chest radiography was present in 48.61% of the patients. Five patients had tuberculosis osteomylitis without involvement of the joint.
