PURPOSE: The purpose of this study was to assess the knowledge of pharmacists practicing in Palestine of issues related to using psychotropic medications in older people. METHODS: The study was conducted with a cross-sectional observational design using a questionnaire. A total of 400 pharmacists responded to a 19-statement knowledge test related to the use of psychotropic medications in older people. The study was conducted from July 2016 to February 2017. The reliability and internal consistency of the study tool was assessed using the test-retest method and the Cronbach alpha. Categorical groups were compared using the chi-square test and the Spearman rank correlation. RESULTS: On the 19-statement knowledge test, the median score was 55.3% with an interquartile range of 21.9%. In a comparison of the demographic and practice-related variables of the pharmacists who scored ≥ 50% on the 19-statement knowledge test with those who scored < 50%, age, gender, and having taken a course on psychotropic medications were found to be significantly associated with performance, as shown by the chi-square test and Spearman correlation. CONCLUSION: Pharmacists practicing in Palestine possess less than optimal knowledge of issues related to the use of psychotropic medications in older people. Continuing educational interventions and/or training might be helpful in improving pharmacists' knowledge of issues related to using psychotropic medications in older people.

1. A simplified vision test chart which is composed of test types of arabic figures and Landolt's rings for 0.1, 0.3, 0.5, 0.8 and 1.0 was designed by the author. 2. The test chart may be used at school for screeing the students who have decreased vision in early stage, and so school myopia can be prevented or cured by medical treatment. 3. It is also recommended to be used for testing the vision of students once every month at home to preserve good vision and prevent school myopia which is so much increased among the students that it has become a serious social problem in Korea.

The accuracy of vision test chart is very important in examination of the visual acuity. The author examined the accuracy of the Cheongsan Vision Chart which is an imitative print of Dr. Chun Suk Hahn's Vision Test Chartby measuring it's test types of Landolt's rings, Arabic figures, Korean letters and pictures in detail with micrometer and surgical loupe. The errors in size of test types of Cheongsan Vision Chart to the standard size which was authorized by the Ministry of Health and Social Affairs of Korea in 1972 for the Chun Suk Hahn's Vision Test Chart are found as follows: 1. Error in Landolt's rings. 0.2-32.7%, av. 9.0%. Error over+/-10% in 35.7%. 2. Error in Arabic figures. 0.1-70.4% av. 12.8%. Error over+/-10% in 47.6%. 3. Error in Korean letters. 0.2-55.9% av. 15.4%. Error over+/-10% in 57.1%. 4. Error in pictures. 0.2-15.1% av. 0.9%. Error over+/-10% in 8.1%. In this study the author found that the Cheongsan Vision Chart is lacking in accuracy for examination of visual acuity.

Argon laser iridotomy was performed on 67 eyes, 49 patients with angle-closure glaucoma: 24 eyes(18 patients) with acute angle-closure glaucoma, 15 eyes(12 patients) with chronic angle-closure glaucoma, 4 eyes(4 patients) with pupillary block glaucoma in aphakia, 6 eyes(4 patients) with glaucoma to uveitis, and 18 fellow eyes on the patients who have monocular angle-closure glaucoma. Iridotomy holes were satisfactorily produced in every eye treated except one eye, 64 eyes(95.5%) having one or two treatment, but failed in one eye with acute type, The procedure was easily done with a small amount of laser energy when it used in the short duration of 0.05 second only rather than the long duration above 0.05 second or others. Postoperatively, of 38 eyes with primary angle-closure glaucoma treated successfully, 12 eyes(31.5%) required no medication, 21 eyes(55.3%) needed the addition of either one or two topical drugs, and filtering surgery was necessary in 5 eyes(13.2%). It was related to the extent of peripheral anterior synechiae. Other 26 eyes required no medication. The closure of iridotomy holes was rare and easily treated in two eyes with uveitic angle-closure glaucoma. And laser iridotomy revealed no major complication.

The cognitive domain of number processing has been known to be separable from that of language. Further, the number processing consists of Arabic and verbal number systems which could be also separable from each other. We report a 49-year-old woman who showed a dissociation between Arabic and Korean verbal numbers. Her impairment in number processing was characterized by the defective comprehension and expression of Korean verbal umbers, without notable defects in those of Arabic numbers. A follow-up examination revealed a further dissociation within the processing of Korean numbers, showing persistent impairment of number comprehension with improvement of number expression. In dealing with numbers with more than two digits, she showed syntactic errors characterized by uttering a string of single digit numbers(I.e., 365) rather than stating them as a whole number(365). Furthermore, auditory comprehension was also more accurate when the numbers were presented as an array of single digit numbers than a whole number with units. However, these syntactic errors were not observed on an automatic counting task. The evidence of separable representation of Arabic and Korean number system could be drawn from these observations, and therefore we propose the possibility of dual number processing pathways, one for a simple numbering system without semantic mediation and the other for a complex, multidigit numbering with semantic mediation.

The author designed new pseudoisochromatic tests for detecting, classifying and estimating the degree of color defectives to meet the increasing need for a test of color vision in Korea. All colors used in these tests were theoretically selected from the isocolor zones for protan, deutan and tritan drawn in the C.I.E. chromaticity chart by Judd. The tests contain 16 plates with arabic figures and 5 with winding lines, and are divided in two sections: 12 tests for screening and 9 for qualitative and quantitative diagnostic tests.

STUDY DESIGN: Cross-sectional screening. PURPOSE: This study was conducted to determine if there is any association of the three microsatellite markers on chromosome 19p 13.3 in unrelated Saudi Arabian girls who were suffering with adolescent idiopathic scoliosis (AIS) and their healthy siblings. OVERVIEW OF LITERATURE: The genetic influence on the development of familial scoliosis has been previously described, but the genetic influence on AIS still remains unknown. Three microsatellite markers (D19S216, D19S894, and DS1034) of chromosome 19p 13.3 were reported to be significantly associated with familial scoliosis. This cross-sectional screening was carried out in AIS patients and their siblings. METHODS: For eleven Saudi Arabian girls who were treated for AIS and their 11 siblings, we performed a linkage analysis using parametric and nonparametric methods and using GENEHUNTER ver. 2.1. Multipoint linkage analysis was used to specify an autosomal dominant trait with a gene frequency of 0.01 at the genotypic and the allelic levels. One sided Fisher's exact tests were used in the analysis of the contingency tables for the D19S216, D19S894 and DS1034 markers. RESULTS: The analysis between the patient group and the healthy siblings showed that at the genotypic level there was a significant association of the markers and scoliosis (D19S894 [p=0.036], D19S216 [p=0.004], and DS1034 [p=0.013]). Yet at the allelic level, there was no statistically significant association of the markers between the AIS patients and their siblings. CONCLUSIONS: Our pilot study shows that there is a genetic influence between the AIS patients and the siblings. We believe large scale genetic screening is warranted for the patients with AIS to identify beyond any doubt the influence of these markers.

OBJECTIVES: To describe the step-by-step person-centered, theory-based development of the KELA.AE app for Arabic speaking hemodialysis patients. METHODS: A step-by-step person-driven theory-based approach was conducted to develop a self-monitoring and educational dietary app for hemodialysis patients. The development follows the Integration, Design, Assessment, and Sharing (IDEAS) framework. Qualitative, semi-structured interviews with 6 hemodialysis patients and 6 healthcare practitioners (dietitians and nephrologists) were performed to assess the need for an app, the willingness to use an app, and features desired in an app. RESULTS: The KELA.AE app, which includes a self-monitoring feature, CKD-friendly recipes, and a theory-based, evidence-based educational feature was developed. Qualitative analysis of interviews revealed two predominant themes from patient interviews ‘Experience with the diet’, ‘App evaluation’, and one theme from interviews with healthcare practitioners ‘App evaluation’. Patients expressed frustration with current accessibility of dietary information along with the need for educational materials in the app. The review of the KELA.AE prototype was positive overall, and patients reported a willingness to use the app. Healthcare practitioners considered the app accurate, simple, and culturally sensitive but expressed concerns about app misuse and the replacement of healthcare practitioners. CONCLUSIONS: The KELA.AE app was found to be satisfactory and supportive of the participants' needs. Changes were made to the app as suggested during the interviews.
