Acute aortic dissection mimicking acute abdomen in a 14‐year‐old boy

Aortic dissection is extremely rare in children. Although it usually presents with severe chest pain, atypical clinical presentations mimicking various illnesses may cause misdiagnosis. In this report, the case of a 14‐year‐old boy with symptoms suggestive of acute abdomen, which was finally diagnosed as aortic dissection, is discussed.     

Equine herpes virus type 1 (EHV-1) and 4 (EHV-4) infections in horses and donkeys in northeastern Turkey

The herpesviruses infections in equides are caused by five different serotypes of viruses, belonging to family Herpesviridae. The goal of this study was to conduct a seroepidemiological investigation of equine herpesvirus type 1 (EHV-1) and type 4 (EHV-4) in horses and donkeys raised in two provinces and their villages in northeastern Turkey. A total of 666 samples from 423 horses and 243 donkeys that were not immunized against these infections were tested with ELISA. While 52.48% of tested horse sera was found to carry specific antibodies to EHV-1, 83.69% of these serums were found to carry specific antibodies to EHV-4. 51. Eighty-five percent of analyzed donkey samples tested positive for EHV-1 and 64.20% of these samples tested positive for EHV-4 antibodies. When the horse and donkey samples were evaluated together, 52.25% were seropositive for EHV-1 and 76.58% were seropositive for EHV-4. This study showed that EHV-1 and EHV-4 infections are quite common in the horses and donkeys being raised in the areas where the study was carried out. In addition, since the area where the study was carried out in the borders of Armenia and Georgia, the high level of seropositive results for these infections leads to the conclusion that we should consider the risk of diseases spreading to neighboring countries. This is the first study to serologically identify EHV-1 and EHV-4 infections in donkeys raised in Turkey.Key Words: Donkey, Equine herpesvirus type-1, Equine herpesvirus type-4, Horse     

Use of pleural fluid C-reactive protein in diagnosis of pleural effusions

The aims of the study were to assess whether C-reactive protein (CRP) is a sensitive marker for discriminating between transudative and exudative and pleural effusions to evaluate whether it can be used to distinguish inflammatory pleural effusions from other types of effusion. Pleural fluid and serum CRP levels were obtained in 97 patients with pleural effusion, using an immunoturbidimetric method (Olympus AU-600 autoanalyser). We compared CRP levels between transudates and exudates, inflammatory effusions and other types of effusion. According to the criteria used, 16 patients were included in the transudate group and 81 patients in the exudate group. Pleural fluid CRP levels were significantly lower in the transudate group (P<0.04; 14.9 +/- 4.9 mg l(-1) and 35.5 +/- 4.9 mg l(-1) respectively). Also, the ratio of pleural fluid to serum was significantly lower in the transudate group (P<0.009; 0.8 +/- 0.5 mg l(-1) and 2.8 +/- 0.7 mg l(-1), respectively). In the exudate group, 35 patients had neoplastic effusions, 10 chronic non-specific pleurisy, 19 tuberculous pleurisy, 16 parapneumonic effusion and one Dressler Syndrome. When these sub-groups were compared, the parapneumonic effusion subgroup CRP levels (mean 89 +/- 16.3 mg l(-1)) were significantly higher than those in the other subgroups, other exudate of neoplastic effusion, tuberculous pleurisy and chronic non-specific effusion and the transudate group (P<0.0001; P<0.0001; P<0.0004 and P<0.0001, respectively). The ratio between pleural fluid and serum CRP was significantly higher in the parapneumonic effusion subgroup than in the neoplastic subgroup (P<0.0002; 6.6 +/- 2.7 mg l(-1) and 1 +/- 0.2 mg l(-1), respectively). Pleural fluid CRP levels > 30 mg l(-1) had a high sensitivity (93.7%) and specificity (76.5%) and a positive predictive value of 98.4%. In the differential diagnosis of pleural effusions, higher CRP levels may prove to be a rapid, practical and accurate method of differentiating parapneumonic effusions from other exudate types. Although the high level of CRP obtained in the exudate group may be due to the number of patients with parapneumonic effusion who were included, the pleural CRP level may also be helpful in discriminating between exudative and transudative pleural effusions.

C-reactive protein and coronary heart disease in western Turkey

C-reactive protein (CRP) has been recognized as a useful marker for coronary or cardiovascular risk in healthy subjects or patients with coronary heart disease (CHD) in industrialized societies. We assessed whether CRP could serve as a marker of prevalent CHD risk in a cross-sectional study of a population with low cholesterol levels (4.61 mmol/L in men and 4.82 mmol/L in women) but higher prevalence of other risk factors. In 1,046 participants of the Turkish Adult Risk Factor Survey in 2000, high-sensitivity CRP as well as other risk variables were evaluated, and CHD was diagnosed, based on clinical findings and Minnesota coding of electrocardiograms at rest. Almost an equal number of men and women > or = 30 years of age constituted the population sample of the western regions of Turkey. Geometric mean value of CRP was 1.9 mg/L (interquartile range 0.8 to 4.3), without revealing a significant difference in gender. CRP was correlated with many variables, notably those involving central obesity, fibrinogen, and apolipoprotein-B, but not with smoking status (regardless of age adjustment). In multiple regression models, blood fibrinogen, waist circumference, total cholesterol, and physical activity grade were independently associated with log CRP concentrations. Among many risk variables, CRP quartiles and systolic blood pressure were, besides age and gender, the only significant independent determinants of CHD. The age-adjusted odds ratio for CHD in the highest as opposed to the lowest quartile was 4.48 (p < 0.001). Even after adjustment for the 5 previously mentioned determinants of CRP, a 4.2-fold increased risk of CHD still persisted between the highest and lowest quartiles. Thus, the observed increased risk was not in large part due to the intermediary effects of fibrinogen, nor were some indicators of insulin resistance, but interaction appeared to be independent of these effects. Thus, CRP values serve as a marker of prevalent CHD risk in populations with low cholesterol levels. This association is independent of, or in addition to, the effects of conventional risk factors, suggesting that the contribution of chronic low-grade inflammation to the atherothrombotic process is present even in the setting of low cholesterol levels.     

Erythrocyte antigen and reticulocyte engraftment after allogeneic hematopoietic stem cell transplantation

The aim of this study was to study the usefulness of erythrocyte antigen (EA) measurement to study engraftment after allogeneic HSCT. In all, 31 consecutive patients receiving HLA-identical bone marrow (BM) (n=13) or peripheral blood stem cells (n=18) were investigated. Apart from the ABO group, 15 EAs representing six minor blood groups were followed by the simple tube agglutination technique. A total of 20 (64.5%) patients received ABO-identical, eight (25.8%) received ABO minor and three (9.7%) received ABO major mismatched grafts. In all, 29 patients were followed for a median of 12 (6-16) months; 65% of the patients expressed donor type EA 1 month and almost all did so 6 months after transplant. Reticulocyte engraftment was significantly shorter than EA engraftment (median 18 vs 35 days) (P=0.001). Patients who received PB stem cells showed significantly faster EA and reticulocyte engraftment than patients who received BM stem cells (P=0.038 and 0.025). ABO compatibility did not have an impact on reticulocyte and EA engraftment (P=0.4 and 0.55). The earliest donor type EA detected was from the Rh and Kidd system. These data suggest that EA and reticulocyte assays are useful in monitoring engraftment.     

Cytotoxic and Antibacteriial Actiivity of the Mixture of Olive Oil and Lime Cream in Vitro Conditions

The mixture of olive oil and lime cream has been traditionally used to treat external burns in the region of Hatay/Antakya and middle Anatolia. Olive oil and lime cream have been employed by many physicians to treat many ailments in the past. A limited number of studies have shown the antibacterial effect of olive oil and that it does not have any toxic effect on the skin. But we did not find any reported studies on the mixture of olive oil and lime cream. The aim of this paper is to investigate the cytotoxic and antibacterial activity of olive oil and lime cream individually or/and in combination in vitro conditions, by using disk-diffusion method and in cell culture. The main purpose in using this mixture is usually to clear burns without a trace. Agar overlay, MTT (Cytotoxicity assay) and antibacterial susceptibility tests were used to investigate the cytotoxic and antibacterial activity of olive oil and lime cream. We found that lime cream has an antibacterial activity but also cytotoxic on the fibroblasts. On the other hand olive oil has limited or no antibacterial effect and it has little or no cytotoxic on the fibroblasts. When we combined lime cream and olive oil, olive oil reduced its cytotoxic impact. These results suggest that mixture of olive oil and lime cream is not cytotoxic and has antimicrobial activity.
