Simple Blunt Trauma and Diaphragmatic Rupture Showing Delayed Clinical Signs
Tar?k Ocak,Ramazan Kuaslan,Mustafa Ba?türk,Hakan Yi?itba?
Akademik Acil T?p Olgu Sunumlar? Dergisi (AKATOS) , 2012,
Abstract: The diaphragm provides the progression between certain structures and the chest cavity by means of an anatomic hiatus. The diaphragm is the second most functional muscle structure of the body after the heart. Diaphragm injuries may result from serious blunt or penetrating injuries. While most of the blunt diaphragm infuries are caused by traffic accidents and falls from heights, some may occur as a result of other blunt traumas to the lower chest or epigastrium. Diaphragm injuries may be seen in t 0.8-1.6% of the patients hospitalized due to blunt abdominal trauma. In this study, we will report that a diaphagm injury of a patient who has a history of blunt abdominal trauma was diagnosed six months after the trauma when he was admitted to hospital because of stomach ache and pain in his left chest.

Veli Caglar, Bahad?r Kumral, Ramazan Uygur, Ozan Alper Alkoc, Oguz Aslan Ozen, Husrev Demirel
Forensic Medicine and Anatomy Research (FMAR) , 2014, DOI: 10.4236/fmar.2014.23012
Abstract: Aims: 1) To establish the volume, weight and size of a normal pancreas, spleen and kidney in 114 adult male autopsies; 2) To investigate the relationship between the volume, weight, and size of the pancreas, spleen, and kidney with body mass index (BMI), body surface area (BSA), age, height, and weight. Methods: The normal pancreas, spleen, and kidney volume, weight, and size retrospectively gathered from 114 forensic autopsy cases between the ages of 25 and 88 years. The pancreas, spleen, and kidney volume, weight, and size were available. The parameters used for statistical correlation were the age, height, body weight, BMI, and BSA of the deceased. Results: The volume, weight, and size of all the organs were shown in correlation with the deceased’s height, body weight, BMI, and BSA but not age. The organ volume, weight, and size showed a better statistical correlation with the BSA, BMI, and body weight than the height. Conclusions: The normal reference ranges for organ volume, weight, and size given in this study can serve as a standard to judge atrophy or hypertrophy of organs in post-mortem diagnosis.
Thermal Expansion and Thermal Conductivity Behaviors of Al-Si/SiC/graphite Hybrid Metal Matrix Composites (MMCs)
S. Cem OKUMUS,Serdar ASLAN,Ramazan KARSLIOGLU,Deniz GULTEKIN
Materials Science , 2012, DOI: 10.5755/j01.ms.18.4.3093
Abstract: Aluminum-silicon based hybrid composites reinforced with silicon carbide and graphite particles were prepared by liquid phase particle mixing (melt stirring) and squeeze casting. The thermal expansion and thermal conductivity behaviors of hybrid composites with various graphite contents (5.0; 7.5; 10 wt.%) and different silicon carbide particle sizes (45 μm and 53 μm) were investigated. Results indicated that increasing the graphite content improved the dimensional stability, and there was no obvious variation between the thermal expansion behaviors of the 45 μm and the 53 μm silicon carbide reinforced composites. The thermal conductivity of hybrid composites was reduced due to the enrichment of the graphite component. DOI: http://dx.doi.org/10.5755/j01.ms.18.4.3093

Medical Journal of Bakirk?y , 2012,
Abstract: Median arcuate ligament syndrome occurs when median arcuate ligament pressures the root of the celiac artery and generally it reveals itself with the post-prandial pain. Because of the pressure there will be a significant tightness especially while expirium. Mesenteric ischaemia and low blood ow to gastro-intestinal system occurs related to the tightness and because of these we see the characteristic clinical symptoms of the syndrome. We present the patient whom we diagnosed with multislicde computerized tomograpy.
Sexual differentiation and embryology of the female reproductive system
Ramazan
Turk Pediatri Ar?ivi , 2011,
Abstract: Humans have forty-six chromosomes, including two sex chromosomes, XX in females and XY in males. A gene in the sex-determining region of the short arm of the Y, now referred to as SRY, has been found to direct production TDF, inducing differentiation of cells derived from the genital ridges into testes. In a male fetus, testes produce steroid and protein hormones essential for internal and external anatomic differentiation. Without SRY, gonads develop into ovaries in 2-6 months of gestation. A fetus has a genital tubercle, urogenital groove and sinus, and labioscrotal folds. In females, if there is no androgen effect, these become theclitoris, urethra and vagina, and labia. In males with the efeect androgens genital tubercle forms penis and scrotum. (Turk Arch Ped 2011; 46 Suppl: 115-7)
Modified Technique for Internal Ureteroileal Stenting in Orthotopic Neobladders  [PDF]
Guven Aslan
Open Journal of Urology (OJU) , 2011, DOI: 10.4236/oju.2011.12005
Abstract: We introduce a modified surgical technique for internal ureteroileal stenting to improve cosmesis in patients undergoing ileal neobladder. Internal ureteric stents are secured to the tip of the urethral catheter with nonabsorbable suture facilitating removal of the stents postoperatively 2-3 weeks along with the urethral catheter. This surgical modification was applied to 21 patients of whom no significant surgical or infectious complication due to single urethral catheter was observed. Internal ureteral stenting is simple, safe and inexpensive alternative to conventional methods to support ureteroileal anastomosis in patients undergoing orthotopic bladder substitution.

Open Journal of Earthquake Research (OJER) , 2013, DOI: 10.4236/ojer.2013.24009
Abstract:

This paper investigates the effect of the Van-Ercis, Turkey, (Mw: 7.2)earthquake occurring on 23rd of October, 2011 on the transportation networks in the region. The basic incentivefor this research is to conceptualise the reliability and performance of the networks after the earthquake through the operational and topological analysis of the system. The demand and composition of the traffic along with the behaviour of the pedestrians were taken into account to evaluate the performance of the networks. In addition, the general structure of the cities and towns, as far as planning is concerned, is also paid attention and regarded as one of the main elements for the appraisal. The outcomes obtained are thought very important to be guidance for the expected Istanbul earthquake in the near future.

Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.55045
Abstract:

It is known that expectations of pre-service teachers will change during the process of the school practice especially depending on the interactions they establish with practice teachers and supervisors. The study was conducted at a faculty of education in a big city with pre-service teachers in senior science class using split-plot design. Data were obtained through three measurement levels including initial, intermediate, and final stages in the study which was carried out with 44 preservice teachers 27 of whom were female. Qualitative data were obtained through focus group interviews made with 6 pre-service teachers, 3 of whom were females following measurement levels. Descriptive statistics were used for analyzing the quantitative data while the ANOVA statistic of Friedman which is a nonparametric test was used for analyzing the point differences. Descriptive analysis was used for analyzing the qualitative data and the data were interpreted together with the findings obtained from the quantitative data. It was detected that the initial expectations of the pre-service teachers were higher in the collegiality and leadership categories compared to guidance but their expectations tended to drop dramatically over time. Among the factors that are considered to be the potential factors of the decrease, whether the practice school, which is a new structure, was introduced to the pre-service teachers at the beginning of the academic year and whether they were welcomed in a positive or negative manner at the practice school constituted the most critical turning points.

Klimik Journal , 2010,
Abstract: Objective: The aim of this study was to investigate risk factors for ventilator-associated pneumonia (VAP) which developed in patients admitted to medical intensive care units. Methods: Patients who were 16 years old and above, dependent on a mechanical ventilator for more than 48 hours and without pulmonary infection on first admission were included in the study. STATA 9.0 (College Station, TX, USA) was employed for statistical analyses and p<0.05 was regarded as the significant value. Results: This study included 142 patients and 64 (45.1%) developed VAP. The incidence of VAP was 23.3 cases per 1000 ventilator-days. Univariate analysis showed that duration of mechanical ventilation (p<0.001), length of intensive care unit (p<0.001) and hospital stay (p<0.001), the APACHE II score (p<0.001), blood transfusion (p<0.001), enteral feeding (p=0.025), urinary infection (p<0.001), wound infection (p=0.045), presence of at least one region of infection (p<0.001), chronic obstructive pulmonary disease (p=0.003), diabetes mellitus (p<0.001), prior antibiotics (p=0.003), tracheotomy (p=0.003) and presence of central catheter (p<0.001) were associated with the development of VAP. Logistic regression analysis showed a relationship between VAP and duration of mechanical ventilation (p=0.015), the APACHE II score (p=0.001), blood transfusion (p=0.015), chronic obstructive pulmonary disease (p=0.036), diabetes mellitus (p=0.019) and presence of central catheter (p<0.001).Conclusions: Defined risk factors for VAP should be recognized and an effective infection control program for the prevention of VAP should be applied. Surveillance results should be evaluated regularly in each unit and necessary precautions should be taken.
