Abstract

Nontuberculous mycobacteria (NTM), also known as atypical mycobacteria or mycobacteria other than tuberculosis are environmental organisms that are normally found in soil and water. Many of the mycobacterial species that have been described in the past decade are involved in human diseases, especially in patients with AIDS and immunocompromised HIV-negative patients. In this study, pathogenicity and clinical significance of new species of mycobacteria were evaluated. A total of 63 new species of non-tuberculosis mycobacteria, recognized in the past ten years (2003-2013), were classified in different Runyon groups. Approximately, 40 isolates were reported to infect human. Of these, 27 (67.5%) were non-chromogenic and 13 (32.5%) were scotochromogenic. The majority of the 40 isolates belong to the slow grower group. Photochromogenic species were not pathogenic to human. The most frequent infections included respiratory infections in elderly people and cervical lymphadenitis in children caused by Mycobacterium kyorinense and Mycobacterium mantenii, respectively. NTM also causes disseminated infections, the most frequent agents of which are M. boenickei, M. houstonense, M. neworleansense, and M. brisbanense in immunocompromised HIV-negative persons. Some of the NTMs, such as Mycobacterium riyadhense, are considered the primary pathogens for human. Considering the progressive spread of HIV co-infected mycobacteria in recent years, accurate identification of these agents’ pathogenicity, drug resistance, and appropriate treatment in epidemic regions, such as Iran, is essential.

Abstract

Background: Determining the level of manual ability of children with cerebral palsy has significant role in scheduling care and providing supportive services by organizations such as the a social welfare office. Manual Ability Classification System (MACS) is responsible for this critical matter. In Mazandaran Province, the prediction of manual ability is intuitive and is done without tools. This study aimed to investigate the consistency between operational therapists prediction of future manual function of children with cerebral palsy and MACS scale.

Materials and Methods: This study was designed as a cross sectional trial. The study population consisted of 12 occupational therapists working in Mazandaran’s rehabilitation center under the social welfare office. Firstly, occupational therapists chose 100 children with cerebral palsy and classified their future manual ability into five levels according to their prediction. Then the researcher classified the children based on MACS scale. Finally, the amount of prediction consistency between therapists and researcher was statisticaly analyzed.

Results: The weighted kappa coefficients of MACS scale were 0.671 in first level and 0.747 in fifth level that show good agreement in these two levels. This coefficient was 0.417 in third level and 0.444 in forth level that shows fair agreement. The weighted kappa coefficient was 0.358 in second level that indicates slight agreement.

Conclusion: With prediction consistency between operational therapists and researcher, MACS is used as a suitable means for classifying the level of manual ability in children with cerebral palsy and predicting their needs to adaptive and auxiliary devices by occupational therapists in rehabilitation centers and social welfare offices.

Abstract

Background: Understanding the real needs of children with cerebral palsy and their families  helps the therapists to provide adequate health care service for them. This study aimed to determine the needs  of  mothering handling training for family caregiving of children and youth with CP at home based on the level of gross motor function.

Materials and Methods: This research was a descriptive, analytical and cross sectional study that was performed on 186 children 4-12 year olds with CP from the rehabilitation clinics in the city of Arak. They were selected by simple and purposeful sampling. Clinical tests were Gross Motor Measure Function Classification System Expanded & Revised (GMFCS E&R) to assess the severity of gross motor function lesions and canadian Occupational performance measure (COPM) to determine the needs. Data were analyzed by descriptive tests such as: statistical test and two-way ANOVA.

Results:  The most important need of mothering handling training was self care training specially toileting, feeding, eating and functional mobility related to children with CP in the level of V of GMFCS E&R (transported in a manual wheelchair). There were no significant differences in needs of mothering handling training in areas of sex and severity of gross motor function lesions (p>0.05).

Conclusion: It seems that therapists should combine maternal handling trainings with other interventions in therapy programs, especially in the area of self- care.

Abstract

Background: One of the problems in children with cerebral palsy is impaired eating and drinking liquids. The purpose of this study is to compare the effect of oral motor stimulations on feeding function in the children with spastic cerebral palsy by two medical and family centered approaches.

Materials and Methods: This research was a descriptive-analytical cross sectional study that performed on 40 children 2-8 year olds with spastic Cerebral Palsy from the rehabilitation clinics in the city of Arak. They were selected by simple and purposeful sampling. Applied instruments were Gross Motor Measure Function Classification System Expanded & Revised (GMFCS E&R) and oral motor assessment scale(OMAS). Data were analyzed by statistical tests such as: Kolmogorov-Smirnov, reporting mean, standard deviation, data analysis frequncy distribution table, independent t-test, dependent t-test, chi-square and MANOVA.

Results: The difference of swallowing function assessed by OMAS in both groups managed by family centered and clinician centered approach prior and post management statistialy was meaningful (p=0.001(. The difference between swallowing function of both groups post intervention was not meaningful in view of first and second assessor, also it had no statistical significance(p=0.89 , p=0.07)

Conclusion: In general, we can conclude that oral motor stimulation is effective on swallowing function of cerebral palsy children in both treated groups. The effect of these stimulations on swallowing function in children with cerebral palsy between clinician centered and family centered approaches was equal.

Abstract

Background and Aim: Diagnosis of leukemia is very difficult, therefore, it is necessary to use image processing techniques. The main objective of this study was to provide a system based on intelligent models that could improve the accuracy of the diagnostic system for acute leukemia.
Materials and Methods: The images produced in this study were extracted from the University Degli Studi Dimilan database and processed in the MATlab 2014a software. In this research, Fuzzy-Cmeans method was used in fragmentation and neural network and support vector machine in classification networks.
Ethical Considerations: In this study, all principles of research ethics were considered.
Findings: Feature data were extracted using the original image transfer to RGB, HSV, Lab and Enhanced RGB spaces. The data obtained from the previous step were entered into the SVM network, then the network separated normal data from abnormal data. The results of comparing the output of the proposed method with different educational methods showed the highest mean of accuracy equal to 95.7%.
Conclusion: The application of the proposed network in this study was that eliminate the weak points of all the networks in addition to presenting the advantages of these network. Combining the networks improved the accuracy of output up to 98% and considerably reduced the time required for calculations.
