Abstract

ABSTRACT
Background: This study is conducted to record the advantages of breast milk feeding for infants with cleft lip and/or
palate and to assess whether education of parents has any role to play in diminishing the expected difficulties
associated with feeding techniques.
Materials and methods: The sample of this study consisted of 76 Iraqi infant (45 male, 31 female) with different types
of congenital cleft lip and/or palate. They were seen in the college of Dentistry, university of Baghdad .Every infant
was provided with feeding baby plate, and breast pump sucker and instruction through video films demonstrate
breast feeding to demonstrate breast feeding. Follow up was arranged regarding any possible change in feeding
and the health of infants .A detailed questionnaire forms were completed together with their families (the father or
the mother or both of them) Observational statistic were then performed.
Results: Using feeding baby plate and providing the proper information regarding different feeding interventions and
using expressed milk results in significant improvement when compared with artificial feeding for infants with cleft lip
and/or palate.
Conclusion: Cleft lip and /or palate infants suffer from difficulties during breast feeding. However appropriate and
proper education and counseling by health care provider to the parents of the infant with cleft lip and /or palate
anomalies can reduce problems for the infant with the added advantage of continuing breast feeding.
Key words: Cleft lip and palate, Breast feeding, artificial feeding, Lactation education. (J Bagh Coll Dentistry

Abstract

Porous silicon multi layer has been prepared by photo-chemical etching of n-type silicon wafer at different etching time (10, 20, 30, 40)min with different illumination intensities of (10, 15, 20, 25) mW/cm2. These intensities lead to form porous silicon systems of size in the range (2.85-4.02)nm. SEM images indicated that the surface of the etched layer has pore-like structure with different pore sizes and porosities. The measurement of Raman scattering in porous silicon showed a red shift of the phonon frequency which increased with increasing the etching time and illumination intensity

Abstract

The unsaturated fatty acid consists of oleic and linoleic acids. Both of these acids contain carbonyl groups and double bonds. The carbonyl group structure enhances the adsorption process of the palm olein on the metal surface. However, not much work has been reported on the use of palm olein as corrosion inhibitor. This paper focuses on the effect of palm olein as corrosion inhibitor for aluminum in 1 M HCl solution. Aluminum samples were exposed in 1 M HCl solution with or without the presence of inhibitor for weight loss measurement test. The corrosion study was performed at room temperature with different concentrations of inhibitors. The sample was retrieved every few hours within 48 hours for weight measurement. It was found that inhibition efficiency of the palm olein is comparable to that of the commercial inhibitor. From the adsorption isotherm study, it was shown that the palm olein protects the Al surface through physical adsorption.

Abstract

Background: Undergraduate dental students are more susceptible to situations of stress that affected quality of sleep, such profiles of stress may result in sleep bruxism and/or awake bruxism, parafunctions that can affect oral and general health. The aim of the study was to evaluate the association of sleep bruxism, awake bruxism and sleep quality among dental students.Materials and methods: A cross-sectional study was performed including 260 Iraqi dental students from university of Baghdad aged from 20to25years old. Students enrolled in the third and fifth class participated in the study. The Pittsburgh Sleep Questionnaire Index (PSQI) was used for data collection. The PSQI was distributed during lecture classes. Sleep bruxism and awake bruxism diagnosis was based on self-reported data.Results: prevalence of sleep bruxism was 9.62% and prevalence of awake bruxism was 15.76%. Statistically significant differences were observed between students who had awake bruxism and the mean of PSQI global score and its components of sleep categories: PSQI global score and day time dysfunction (p<0.001), habitual sleep efficiency (p=0.044; p<0.05) and sleep quality (p=0.046; p<0.05). While for students had sleep bruxism the statistically significant differences were observed in sleep disturbance (p=0.021; p<0.05) and sleep duration (p=0.042; p<0.05).Conclusion: Poor sleep quality was an important factor among dental students, who reported awake bruxism as well as among those who presented sleep bruxism

Abstract

ABSTRACT:BACKGROUND:Combat Gunshot Head Injury is an increasingly important issue with all its drawbacks on the health care system .OBJECTIVE:This study presents an evaluation of traumatic brain injury caused by gunshots and discusses possible predictive factors for the outcome of surgical intervention.PATIENTS AND METHOD:A prospective study performed at Al Shaheed Mohammed Al Majed hospital, Samarra, Saladin, Iraq consisted of 60 patients who underwent surgery for penetrating TBI over a 1 year period (2015 – 2016). All injuries were caused by gunshot.RESULTS: Mean patients’ age was 31.5 years. The Glasgow Coma Scale (GCS) score on admission was > 8 in 43 patients (71.7%) and ≤ 8 in 17 patients (28.3%). Commonest site of brain injury is the frontal lobe (28%). Ballistic trajectory through brain affects the post operative outcome with good outcome (50%) in the anteroposterior bullet trajectory plane. 5 patients (8.3%) died despite surgical management.CONCLUSION:Admission GCS score, bullet trajectory and ventricular involvement are the most powerful prognostic indicator with a score of more than 8, no ventricular hemorrhage, anteroposterior trajectory of bullet and lesions limited to a single lobe of the brain, have improved surgical outcomes. Early and less invasive surgery in conjunction with short transportation time to the hospital could decrease mortality rates..

Abstract

ABSTRACT:BACKGROUND: Deciding the prognostic factors that influence the surgical result would be useful for judgment planning. Other than that, recognizing the prognostic factors that foresee the clinical course of remaining dissensions may be essential for assist advancement of viable strategies for treatment, particularly when these prognostic components can be changed.OBJECTIVE: The aim of the study was to determine the positive, negative and unrelated predictors of surgical outcome for patients undergo lumbar discectomy. PATIENTS AND METHODS: A prospective cohort study including consecutive series of 102 patients, who had undergone surgical management for herniated lumbar discs at the private nursing home hospital in Baghdad, Iraq, between March 2017 and March 2018, were included in this study. The patient population consisted of 45 females and 57 males, ranging in age from 22 years to 65 years at the time of initial diagnosis with a mean age of 44.7 ± 7.9 years. A full available investigation had done including X-rays and M.R.I.RESULTS: Male: female ratio equals 1.3:1, 69.6% are employed, 58% with no or basic educational level and 70% of patients were smokers. Average duration of low back pain and radicular pain were 8 and 4 months respectively. In 89% there was disc space height loss, the level lumbar disc herniation was at L4-L5 in 45% while at L5-S1 in 41%. Mean Oswestry disability index (ODI) was 63 and 27.7 respectively both pre and postoperatively. Mean Visual Analogue Score (VAS) for low back pain for pre (4.8) and postoperative period (1.8) while mean VAS for radicular pain preoperatively was 4.3 and postoperatively 1.4. The mean MCID – TUG test was 4.3 seconds.DISCUSSION: Comparisons have been made with other studies regarding preoperative predictor factors and the lumbar discectomy surgical outcome. CONCLUSION: -The good surgical outcome can be predicted with MCID ~ TUG test ≥ 3.4 seconds, TUG < 14 seconds, L5 - S1 disc level, annular defects, employed status, higher education, preserve disc height, BMI < 25, short duration of < 3 months of preoperative radicular pain. Lower VAS low back pain preoperatively of < 4 will have better postoperative results regarding back pain.-Worse outcome predictors include male gender, tall patients >180 cm, low level of education, unemployment, higher preoperative ODI ≥ 40%, positive tension root signs, > 50 % disc height loss, preoperative motor deficits, prolonged duration of preoperative low back pain (> 3 months) and higher preoperative VAS score radicular pain (≥ 4). Also to mention that higher preoperative VAS low back pain (≥ 4) will be translated to more postoperative radicular pain.-Factors that have no effect on outcome include age and smoking.KEYWORDS: Outcome, predictor factors, lumbar discectomy.
