Back ground: Oral isotretinoin is recommended
for sever nodulocystic acne in the doses 0.5-
2mg/kg/day which is usually associated with higher
incidence of adverse effects. To reduce the
incidence of side-effects and to make it more costeffective,
the lower dose regimen of isotretinoin has
been used.
Aim: To compare the efficacy and tolerability of
oral isotretinoin 10mg and 20mg/day in acne
vulgaris.
Methods: one hundred and twenty patients with
acne vulgaris were randomized into two treatment
regimens each consisting of 60 patients. The first
was treated with 10mg/day and the second group
with 20mg/day for 24 weeks. Fifty five patients
from the first group and 47 patients from the second

Background: Bullying victimization is a major public health problem. Interest in bullying in Arab world is a recent phenomenon. Publication on victimization in Iraq is scares. Therefore this study was conducted to report bullying among students of Iraqi schools.
Methods: A total of 302 students from Baghdad was selected by a cluster random sample to include in this study. An Arabic version of standardized questionnaire was obtained from the International (ISPCAN). Identification of bullying (bullies, victims and sexual victims) was done by using a cutoff for the scoring of bullying manifestation in the questionnaire depending on three repeated action at least to consider as bullies. P value less than 0.05 was considered significant fo

The theories and applications of speaker identification, recognition, and verification are among the well-established fields. Many publications and advances in the relevant products are still emerging. In this paper, research-related publications of the past 25 years (from 1996 to 2020) were studied and analysed. Our main focus was on speaker identification, speaker recognition, and speaker verification. The study was carried out using the Science Direct databases. Several references, such as review articles, research articles, encyclopaedia, book chapters, conference abstracts, and others, were categorized and investigated. Summary of these kinds of literature is presented in this paper, together with statistical analyses

Background: The 2006-2007 Iraqi Mental Health survey (IMHS) reported surprisingly low prevalence of alcohol and drug abuse in the Iraqi population. Since then anecdotal and clinical reports have suggested that abuse of alcohol and drugs in Iraq has increased. To investigate this possibility, we conducted a survey of drug and drug abuse at youth centers in Baghdad.
Objective: To investigate this possibility, we conducted a survey of drug and drug abuse at youth centers in Baghdad.
Patients and methods: A total of 2678 persons were included in this survey with male to female ratio of 3.8:1. They were randomly selected from youth centers located in different sectors in Baghdad (Sader city, Al-Rusafa side and Al-Karkh side). Composite

In the current study, different concentrations of miltefosine drug, which is the first effective and safe oral treatment for visceral leishmaniasis, was evaluated against L. donovani promastigotes in comparison with pentosam drug. Direct counting microscopic assay was used to find 50% inhibitory concentration (IC50) of miltefosine and pentostam against L. donovani promastigotes. The IC50 of miltefosine drug was 45.42μg/ml, 46.76μg/ml and 36.68μg/ml after 24 hr, 48hr and 72hr respectively, In comparison with IC 50 of pentostam drug was 75.39 μg/ml after 72hr. There were significant differences (P˂0.05) between IC50 values of miltefosine and pentostam drugs from first day to third day.

This study aims to find out the effect of the mediator on scaffolding fourth yearstudent- teachers' teaching competencies and their self-efficacy. The present study combines scaffolding and self-efficacy by using a mediator on scaffolding students affects teaching competencies and selfefficacy and from the results of which the existence of student-teachers’ selfawareness was ensured as an effect of the same independent variable. The model affects their teaching competencies and led them to be aware of the needs of their pupils and themselves.
