Abstract

This paper presents the results of the slope failure analyses from fracture distributions and their relation to tectonic activity; the analytical results have indicated that the phenomena of plane failure, wedge failure and toppling failure can occur at almost of the survey sites within the study area. The statistical data show that the fracture orientation mainly develop in the E-W, N-S and NW-SE due to the influence of tectonic activity. The occurrence of them together with the rock slope surface orientation has formed plane failure on the slope surface of the 3B highway in the E-W direction and the types of wedge failure and toppling failure on the slope surface of the highway in the N-S and NW-SE direction.

Abstract

Bonding the teeth with orthodontic brackets via orthodonticadhesive is essential stage in orthodontic treatment. But,still the failure bracket due to orthodontic or functional forcescould be the predominant problem through the orthodontictreatment, in addition to the enamel fracture; in cases the bracketfailed at the enamel–composite interface completely orpartially (scores 0, 1, 2) as suggested by Artun and Bergland.This study is a clinically attempt to evaluate the failure–bracket number and the bracket failure sites, for three orthodonticcomposite systems, which were two paste (Concise);nomix (Right ON) and light cure (Transbond). These adhesiveswere used in bonding a stainless steel brackets to the teethof adhesive system.The number of the failed brackets through 18 months oftreatment were recorded and the site of the failed bracketswere observed by magnifying lens (10×) and recorded accordingto the Artun and Bergland index.The results showed that there were no significant differencesof failed brackets at p < 0.05 and 0.01 levels amongthese three composite systems, but the Concise adhesive hadthe least failure–brackets.The failure sites of the failed brackets for the three bondingsystems were occurred at scores 2 and 3, while the Concisesystem had the highest percentage of score 3 site (80%)(composite bracket interface).

Abstract

Summary:
Background: Acute renal failure (ARF) in children is a catastrophic, life -threatening
event
Aim of the study: the aim of the present study is to find out the etiology and outcome
of patients with acute renal failure below two years of age admitted to the hospital.
Patients and methods: A prospective study was carried out on children below 2
years of age (with exclusion of neonatal period) presented with acute renal shut down
admitted to Children Welfare Teaching Hospital during the period from Jan. 1st
,
2007tojan30th
,2008.
Results: the study group included 100 patients with acute renal failure, 69 males and
31 females with M/F ratio 2.2:1.Age range was between (2 months - 2 years).
Prerenal ARF was the commonest type seen in 67(67%) patients and hypovolemia
due to (gastrointestinal loss) was the prominent etiology it was found in 53(53%)
cases. ARF due to renal and post-renal causes found in 21(21%) and 12(12%) cases
respectively, six (6%) patients only presented with non-Oligouria.
Forty four patients (44%) required peritoneal dialysis, while(56)patients improved on
conservative management only and most of them (53 %) were the pre-renal group.
Ninety two (92%) patients had either complete or partial recovery of their renal
function, eight (8%) patients died from ARF.
Conclusion: prerenal ARF particularly hypovolemia secondary to gastrointestinal
loss was the most common causative group of ARF in our patients, with good
prognosis for the recovery of renal function in most patients. To evaluate and validate
markers of acute kidney injury more prospective clinical studies required.

Abstract

ABSTRACT:BACKGROUND:Cardiac troponins provide diagnostic and prognostic information in acute coronary syndromes, but their role in acute decompensated heart failure is unclear.OBJECTIVE:Describe the association between elevated cardiac troponin levels and adverse events in patients hospitalized with acute decompensated heart failure.METHODS:Troponin was measured at the time of admission in 340 patients who were hospitalized to Baghdad Teaching Hospital for acute decompensated heart failure between October 2007 and October 2008. A positive troponin test was defined as a cardiac troponin I level of 0.5 ng/mL or higher.RESULTS:Overall, 30 patients (8.8%) were positive for troponin. Patients who were positive for troponin had lower systolic blood pressure on admission [138±30 vs. 144±30 mmHg, P value 0.01], a lower left ventricular ejection fraction [mean 33±15 % vs. 38±16%, P value 0.002] and higher in-hospital mortality [3 patients (10%) vs 8 patients (2.58%), P value 0.001] than those who were negative for troponin. The adjusted odds ratio for death in the group of patients with a positive troponin test was 2.45 (95% confidence interval [CI], 2.14 to 2.79; P<0.001) by the Wald test).CONCLUSION:In patients with acute decompensated heart failure, a positive cardiac troponin test is associated with higher in-hospital mortality, independently of other predictive variables
