Ultrasound versus computed tomography scan findings in pediatric blunt abdominal traumas

Objective: We aimed to evaluate the performance of ultrasonography (US) versus computed tomography (CT) scan in detecting intra-abdominal injury among pediatric patients with blunt abdominal trauma. Methods: Pediatric patients aged<18, who were admitted to the emergency department (ED) due to abdominal trauma and underwent both US and CT scan were evaluated retrospectively. Results: A total of 732 pediatric patients were included in this study. Pathology was detected on US of 418 (57.1%) cases, whereas, intra-abdominal pathology was detected in CT scan of 359 (48.7%) cases. The sensitivity of US in detecting pathology (fluid and/or organ injury) was 95.3%, and its specificity was 79.6%. The sensitivity of US in detecting free fluid was 94.9%, and its specificity was 80.5%. In patients with unstable and stable hemodynamic, the sensitivities of US in detection of pathology (fluid and/or organ injury) were 97.6% and 91.6%, and its specificities were 74.3% and 80.9%, respectively. Conclusions: In our study, the sensitivity of US in terms of detecting pathology in pediatrics with blunt abdominal trauma was high, whereas the specificity of US was low

The effect of doxorubicin on rats that received toxic and carcinogenic benzo(a)pyrene.

Benzo(a)pyrene (B(a)P) is a polycyclic aromatic hydrocarbon with carcinogenic and toxic effects. Doxorubicin is a DNA-interacting drug widely used in chemotherapy. In the present study we investigated the effects of doxorubicin on rats that received benzo(a)pyrene. Sprague-Dawley male rats, 3-4 months old, were divided into 5 groups (n=9 per group). Group 1 (controls) received normal saline intraperitoneally (i.p.) and intragastrically (i.g.), Group 2 (controls) similarly received corn oil i.p. and i.g., Group 3 received corn oil soluble benzo(a)pyrene (10mg/kg b.wt every 10 days for 40 days), Group 4 received doxorubicin (4 mg i.p. on 3 consecutive days), Group 5 received doxorubicin for 3 days (as in group 4) followed by benzo(a)pyrene as in group 3. After twenty-four hours urine samples were collected, heart blood, liver and kidney tissue samples were obtained. Biochemical data were evaluated on urine and blood; liver and kidney tissue samples were investigated histologically. Uric acid, urine creatinine, creatine clearance, urea nitrogen, serum creatinine values, serum glutamic oxaloacetic transaminase (SGOT, AST), serum glutamic pyruvic transaminase (SGPT, ALT), alkaline phosphatase (ALP, AP), superoxide dismutase (SOD), catalase (CAT) activities and malondialdehyde (MDA) levels were significantly different in the 3rd group compared with control groups. Most of the parameters group 5 were statistically similar to control values. Histological appearance of the liver and the kidney tissue samples supported the improvement in the 5th group. The result of our study indicated that liver and kidney functions impaired with benzo(a)pyrene may be partially restored by doxorubicin

Vitamin D in the light of current knowledge

Vitamin D is an essential factor not only for homeostasis of calcium and phosphorus, but also regulates hundreds of genes involved in cell differentiation and cell proliferation through nuclear vitamin D receptor of its active form, 1,25-dihydroksyvitamin D3. Besides its beneficial effects on bone health, vitamin D contributes to the prevention of various malignancies, autoimmune and allergic diseases, cardiovascular and infectious diseases as a result of their anti-inflammatory and immune modulatory properties and effects on cytokine levels. Low vitamin D levels are associated with so many diseases such as malignancies, autoimmune disease, diabetes, hypertension and infectious disease. Current knowledge about vitamin D and the effects of vitamin D on musculoskeletal system and the other systems are discussed in this review. [Archives Medical Review Journal 2013; 22(2.000): 259-271

Rural Children's Perceptions of Happiness: What is Happiness? How Do They Make You Happy? How Can They Be Happy?

WOS:000530128700015This study aims to investigate the perception of happiness of children in the middle childhood stage and adolescents. In this context, it was sought to answer the questions of how children define happiness, how they make people around them happy, and what other people around them do to make them happy. Also, it was investigated whether there is a difference between children of middle childhood stage and adolescents regarding those questions. The research employed a qualitative phenomenological method, and the sample of the study was selected from a rural area of Agri province. The study group consisted of 95 participants 48 of whom are at middle chilhood and 47 pre -adolescents. Within the scope of the research, data were obtained through semi -structured interviews that were formed through expert opinions. Content and descriptive analyses were used in the analysis of the data. As a result of the research, it was found that there was a similarity between the methods of children's making and being happy; however, there were some differences in terms of development levels and gender. Besides that, considering the obtained results, there was a consistency with the existing litreature about the perceptions of happiness. The results were discussed in terms of the literature on happiness, and child development and education

Cytotoxic Effects of Functional Foods Momordica charantia L. and Lycium barbarum L. Extracts on Prostate Cancer Cells

Prostate cancer is a growing health problem around the world. Although there are different therapeutic methods, none of them possessed complete efficacy up to now. Therefore, discovery of novel anti-cancer drugs is important. Bitter melon (Momordicacharantia L.) and Goji berry (Lycium barbarum L.) as functional foods may prevent prostate cancer. In this study, we investigated the effects of ripe and unripe fruit (peel and pulp), seed and aril extracts of bitter melon and also black and red fruit extracts of L. Barbarum on cancer cell viability. In vitro cytotoxicity activities of the extracts (0–150 µg/mL) against androgen dependent (LnCAP) and independent (PC-3) prostate cancer cell lines were screened by MTT assay. Our results reveal that, all tested extracts exhibited cytotoxic activity towards the investigated tumour cells and bitter melon seed extract was the most effective extracts having an IC50 value of 14.7 µg/mL for LnCAP cells. The overall findings demonstrate that specially seed extract of bitter melon, could be a potential source of a new anti-cancer compound and serve as a possible drug against prostate cancer

Are the angiotensin-converting enzime gene and acticity risk factors for stroke? São fatores de risco para acidente vascular cerebral o gene e a atividade da enzima conversora de angiotensina ?

Stroke is a multifactorial disease in which genetic factors play an important role. This study was carried out to determine angiotensin-converting enzyme (ACE) gene polymorphism in Turkish acute stroke patients and to establish whether there is an association of angiotensin-converting enzyme gene I/D polymorphism with clinical parameters. In this study 185 patients and 50 controls were recruited. We have investigated the association among the allelic distribution of the insertion/deletion (I/D) polymorphism of the ACE gene identified by polymerase chain reaction. Distribution of ACE gene I/D genotypes and allele frequencies in patients were not significantly different from controls. D allele frequencies were 57.8% in patients versus 53.0% in controls and I allele 42.2% versus 47% respectively. History of hypertension, stroke, renal, heart and vessel diseases incidence and age, gender, systolic-diastolic blood pressures and creatinine levels were significantly high in patients. But these results and ACE activities had no significant differences among the ACE genotypes in patients and controls. Our results suggest that the ACE gene polymorphism is not associated with the pathogenesis of stroke in Turkish stroke patients.<br>O acidente vascular cerebral (AVC) é doença multifatorial em que fatores genéticos desempenham papel importante. Este estudo foi desenvolvido para verificar o polimorfismo do gene da enzima conversora da angiotensina (ECA) em pacientes turcos com AVC agudo e estabelecer se existe associação do gene I/D da ECA com parâmetros clínicos. O estudo foi realizado com 185 pacientes e 50 controles. A associação entre a distribuição alélica da inserção / deleção (I/D) do polimorfismo do gene da ECA foi estudada pela reação em cadeia da polimerase. A distribuição dos genótipos I/D do gene da ECA e suas freqüências não apresentaram significância estatística quando comparados os pacientes e controles. As freqüências dos alelos D foram 57,8% nos pacientes versus 53% nos controles e dos alelos I 42,2% versus 47% respectivamente. Antecedentes de hipertensão, AVC, doença renal, doenças cardíacas, idade, gênero, pressão arterial sistólica e diastólica e níveis de creatinina foram significantemente elevados no grupo dos pacientes. No entanto estes resultados quando comparados com a atividade e o polimorfismo do gene da ECA não apresentaram diferenças estatísticas entre o grupo de pacientes e controles. Nossos resultados sugerem que o polimorfismo do gene da ECA não é associado com a patogênese do AVC em paciente turcos
