A Retained Bullet in Pericardial Sac: Penetrating Gunshot Injury of the Heart

Penetrating cardiac trauma is rarely seen but when present there is a short time lag to keep the patients alive. Cardiac gunshot injuries are exceptional and it occurs mostly during interpersonal disagreements casualties or a mistakenly fired gun nowadays. Here we present a case of cardiac gunshot injury from the war of Kobani, Syria. The patient was mistakenly diagnosed to have a sole bullet in the left shoulder while he had a penetrating cardiac trauma with a bullet in the heart and pericardial effusion possibly giving rise to pericardial tamponade. Luckily the cardiac gunshot injury was noticed one day later and the patient was referred to a tertiary hospital. Intrapericardial bullet was conservatively followed up. The patient was discharged one week later after resection of the bullet in the shoulder

Lifelong learning perception metaphoric of nurses

The aim of the study was to reveal the perceptions of nurses about lifelong learning nurses via metaphors. Qualitative and quantitative study pattern was used. The cosmos of the research was constituted by all the nurses (N: 325) who worked in an official inpatient care institution affiliated to T.C Ministry of Health in Istanbul. Research was realized with 269 volunteer nurses without any pick of sample. An information form collecting data about age, gender, marital status, graduated programme, department worked, total years worked as a nurse, whether they willingly became a nurse to determine the characteristics of the nurses. Each nurse was asked to complete the blanks in the sentence, 'Lifelong learning is like a/an.....................because..................'to reveal the perceptions of the nurses about the lifelong learning. The metaphors were gathered under 5 conceptual categories in terms of purposes-important-benefit of life long learning on the basis of metaphoric expressions. Nurses produced 139 metaphors for life long learning. More than half of the metaphors (95) were represented by a nurse. The remaining 46 metaphors were expressed by 2-20 nurses. The top four metaphors were baby, water, tree, and children, respectively. Most of the nurses regard lifelong learning as a necessity of constant change and development while thinking that learning realizes at every age and every place either consciously or unconsciously and lastly, they render lifelong learning possible, only by learning to learn. According to these conclusions, metaphors may be utilized as a strong research mean in order to reveal, understand and explain individual perceptions and mental images. There is a need for a wide range of qualitative researches analyzing nurses perceptions of lifelong learning and metaphorical analysis of their thoughts concerning lifelong learning. Examination of these researches' results in education programs would provide a big profit in determining nurses points of view towards lifelong learning. (C) 2014 The Authors.

Electron paramagnetic resonance study of radiation-induced paramagnetic centers in succinic anhydride single crystal

Succinic anhydride single crystals were exposed to 60Co-gamma irradiation at room temperature. The irradiated single crystals were investigated at 125 K by Electron Paramagnetic Resonance (EPR) Spectroscopy. The investigation of EPR spectra of irradiated single crystals of succinic anhydride showed the presence of two succinic anhydride anion radicals. The anion radicals observed in gamma-irradiated succinic anhydride single crystal were created by the scission of the carbon-oxygen double bond. The structure of EPR spectra demonstrated that the hyperfine splittings arise from the same radical species. The reduction of succinic anhydride was identified which is formed by the addition of an electron to oxygen of the C–O bond. The g values, the hyperfine structure constants and direction cosines of the radiation damage centers observed in succinic anhydride single crystal were obtained. © 2017 Elsevier B.V

Electron paramagnetic resonance study of gamma-irradiated potassium hydroquinone monosulfonate single crystal

Gamma-irradiated potassium hydroquinone monosulfonate (PHM) single crystals were investigated between 125 and 300 K using the electron paramagnetic resonance (EPR) technique. Between 125 and 300 K no changes in the spectra have taken place. The spectra were found to be temperature independent. The investigation of EPR spectra of irradiated single crystals of PHM showed the presence of two PHM anion radicals. The g values of the radiation damage centers observed in the PHM single crystal and the hyperfine structure constants of the free electron with nearby protons were obtained. © 2016 Informa UK Limited, trading as Taylor & Francis Group

Quantitative Assessment of Palatine Tonsils in Healthy Children and Adolescents With Shear-Wave Elastography

The normal elasticity and velocity values for palatine tonsils (PTs) in healthy children and adolescents were defined using shear wave elastography, and the relationship with potential factors affecting these values was assessed. This prospective study included a total of 80 cases with ages ranging from 3 to 17 years. Sex, age, and body mass index (BMI) were recorded. Elasticity and velocity measurements of both PTs and the relationship with basic descriptive data were investigated. For statistical analyses, independent-samples t tests and Spearman rho (r) correlation coefficient were used. Quantitative variables are shown as the mean +/- SD, and categorical variables are shown as n (%). The mean age was 10.6 +/- 6.4 years, and the mean BMI was 17.40 +/- 4 kg/m(2). The mean elasticity and velocity values were 9.38 +/- 1.27 kPa and 1.76 +/- 0.11 m/s for the right PT and 9.57 +/- 1.43 kPa and 1.79 +/- 1.04 m/s for the left PT, respectively. The mean tonsil volume was 2.44 mL for the right PT and 2.36 mL for the left PT. There were no significant differences in elasticity, velocity, and volumes when comparing location, age, or sex groups. No significant correlations were observed between the elasticity and velocity values and BMI. In conclusion, this preliminary work can be used as a reference for the diagnosis of PT diseases. Future comprehensive studies are necessary to establish the role of elastography in the diagnosis of pathologic tissue differentiation confirmed by clinical, laboratory, or pathology analyses

Normative values of pancreas stiffness by shear wave elastography in healthy children and adolescents

Purpose To define normal pancreas elasticity and velocity values with shear wave elastography (SWE) in healthy children and assess associations with gender, age, and body mass index (BMI). Methods This prospective study included a total of 100 cases (male: 50; female: 50), aged 3-17 years. Preschool, school, and adolescent periods of 3-6 years (n = 27), 7-12 years (n = 30), and 13-17 years (n = 43), respectively, were created in addition to two groups representing prepubertal and postpubertal periods of 3-10 years (n = 50) and 11-18 years (n = 50), respectively. Demographic data regarding the gender, age, height, body weight, and BMI were recorded. Pancreatic head, corpus, and tail SWE measurements were performed with a convex transducer (3.5-5 MHz). Correlations and comparisons were made for stiffness values between groups. Statistical analyses used Mann-WhitneyU, Kruskal-Wallis, and Spearman's correlation tests. Results Medians (25-75th percentage) of age and BMI were 7 (4.25-10) years and 15 (13-17) years and 17.47 (14.94-19.23) kg/m(2)and 21.22 (17.41-24) kg/m(2)in the two age groups, respectively. The median (interquartile range) elasticity and velocity values for the head, corpus, and tail sections of the pancreas were measured as 9.35 (2.9) kPa and 1.76 (0.26) m/s; 9.3 (2.5) kPa and 1.74 (0.21) m/s; and 8.75 (2) kPa and 1.69 (0.15) m/s, respectively. No significant differences were identified for stiffness values between gender and pancreatic section. Pancreatic stiffness values were significantly different among two (p = 0.001) and three (p = 0.028) age groups, and presented mild positive correlations with age (r: 0.23,p: 0.002), height (r: 0.18,p: 0.01), body weight (r: 0.38,p: 0.003), and BMI (r: 0.37,p: 0.045). Conclusion Normal elasticity and velocity values were defined for the pancreas with SWE in children. Pancreatic stiffness does not significantly change among pancreas parts, but it increases with the transition from childhood to adolescence
