More than 450 distinct types of human papilloma virus recognized via recent molecular techniques. The low and high oncogenic risk-HPV genotypes have an association with a variety of benign and malignant tumors in the oropharyngeal and nasopharyngeal localizations. This study aimed to determine the rate of DNA detection of HPV genotype 6/11 in non-oncologic nasopharyngeal and palatine tonsillar tissues from pediatric patients subjected to adeno-tonsillectomies. A total number of 64 tissue specimens enrolled; 44 non-oncologic nasopharyngeal and palatine hypertrophied tissue specimens from 22 pediatric patients sustained combined adeno-tonsillectomies and compared to 20 nasal trimmed tissues with unremarkable pathological changes (included as apparently healthy control tissues). Recent version of chromogenic in situ hybridization method used for HPV 6/11 DNA detection performed via DNA probes specified for HPV 6/11 low oncogenic - risk genotypes. Among a total 44 tissue specimens obtained from 22 pediatric patients who sustained surgical operations for combined non-oncologic nasopharyngeal and palatine tonsillar hypertrophies, 10 combined nasopharyngeal as well as palatine tonsillar hypertrophied tissues out of 22 combination of such tissues found to contain positive CISH reactions results for HPV 6 / 11 DNA, constituting 45.5% of the total screened tonsillar tissues. No positive– CISH reactions detected in the control tissues. Statistically, a significant difference showed when compared to the control apparently healthy nasal tissues. The significantly detected rates of these low- oncogenic HPV genotypes in both nasopharyngeal and palatine tonsillar hypertrophied tissues are pointing for a one important reservoir tissue site for such infection. In addition, indicating a herald mark for exploring the transmission and pathogenesis dilemma of such an important sexually transmitted infection among, at least, this group of pediatric Iraqi general population.
Background: Regional anesthesia is a common procedure in an adult patient undergoing ophthalmic surgery, but it cannot be done alone in the pediatric age group. General anesthesia is accompanied by complications intra- and post-operatively.
Objectives: to determine whether or not using regional anesthesia in combination with general anesthesia in pediatric eye procedures improves patient outcomes.
Methods: Forty children, with an age range of 6 - 12 years were included in the study that was conducted at Ghazi Al-Hariri Hospital / Department of Ophthalmology and Ibn Al-Haytham (Ophthalmology Hospital), both teaching hospitals, from December 2018 to October 2019. These childr

Pro-inflammatory cytokines can be produced as a result of this illness. Tumor necrosis factor-a is one of these pro-inflammatory cytokines. Materials and Methods. Blood sample were collected from 180 Iraqi participants. Ninety of them is type 1 diabetic patients and other 90 is healthy control .both groups were tested for the incidence of Coxsackie virus B IgG. So the patients groups is divided to two groups according to sero positivity of CVB-IgG .all 180 patients tested to measure of level of TNF-α. Results. The Results showed increasing in levels of TNF-α in CBV po

Show MoreA total of 100 clinical sample from (urine, sputum and swabs of wound , burn and ear) were collected from patients in different hospitals of Baghdad during the period from December 2013 to May 2014. 15 isolates (15%) identified belong to Acinetobacter baumannii, swabs of wounds were represented in high percentage of A.baumannii isolates (40%) while percentage of other samples were variable. Susceptibility of 15 A.baumannii isolates were tested toward 16 different Antimicrobial agents, the results showed all isolates were multi drug resistant. In addition, Polymerase Chain Reaction Technique (PCR) was performed to detection the resistance genes encoding the Oxacillinases enzymes. The PCR analysis showed that the presence of insertion sequ

Several benefits of the use of CO2 laser have been reported for oral surgical procedures. This study aims to evaluate the effect of CO2 laser on soft and hard oral tissues (in vitro study). This study was done on fresh tissues from sheep’s head. CO2Surgical Laser with different operation modes was used; 0.2 mm spot size using different laser parameters on the tongue, and bone making holes, incisions and cutting. The depths and widths of holes and incisions were measured using endodontic file under magnification. The speed of incisions was calculated and the required time for cutting was measured using sport clo

Show MoreCarbon Monoxide (CO) has a significant indirect effect on greenhouse gasses due to its ozone and carbon dioxide precursor, and its mechanism of degradation involving the hydroxyl radical (OH) which control the oxidizing ability of the tropospheric. To understand the effect of human activities on atmospheric composition, accurate estimates of the sources of atmospheric carbon monoxide (CO) are necessary. MOPITT (Measurements of Pollution in the Troposphere) is a NASA Terra satellite instrument designed to allow both Thermal-Infra-Red (TIR) and Near-Infra-Red (NIR) observations to be used to collect vertical CO profiles in the Troposphere via the concept of correlation spectroscopy. The objective of the current stu

Objective: The purpose of the present study was to isolate and identify Enterococcus faecium isolates then detecting its ability of carrying the gene responsible for enterocin production in this species. Materials and methods: Out of 50 samples from different sources (food and clinical sources) were collected for the Enterococcus faecium isolation, and the isolated bacteria Enterococ

Sensing data without an accurate location is worthless, especially in critical applications. The pioneering technique in range-free localization schemes is a sequential Monte Carlo (SMC) method, which utilizes network connectivity to estimate sensor location without additional hardware. This study presents a comprehensive survey of state-of-the-art SMC localization schemes. We present the schemes as a thematic taxonomy of localization operation in SMC. Moreover, the critical characteristics of each existing scheme are analyzed to identify its advantages
