The Relation between the Color M‐Mode Propagation Velocity of the Descending Aorta and Coronary and Carotid Atherosclerosis and Flow‐Mediated Dilatation

Background: To improve clinical outcomes, noninvasive imaging modalities have been proposed to measure and monitor atherosclerosis. Common carotid intima‐media thickness (CIMT) and brachial artery flow‐mediated dilatation (FMD) have correlated with coronary atherosclerosis. Recently, the color M‐mode‐derived propagation velocity of descending thoracic aorta (AVP) was shown to be associated with coronary artery disease (CAD). Methods: CIMT, FMD, and AVP were measured in 92 patients with CAD and 70 patients having normal coronary arteries (NCA) detected by coronary angiography. Patients with acute myocardial infarction, renal failure or hepatic failure, aneurysm of aorta, severe valvular heart disease, left ventricular ejection fraction <40%, atrial fibrillation, frequent premature beats, left bundle branch block, and inadequate echocardiographic image quality were excluded. Results: Compared to patients with normal coronary arteries, patients having CAD had significantly lower AVP (29.9 ± 8.1 vs. 47.5 ± 16.8 cm/sec, P < 0.001) and FMD (5.3 ± 1.9 vs. 11.4 ± 5.8%, P < 0.001) and higher CIMT (0.94 ± 0.05 vs. 0.83 ± 0.14 mm, P < 0.001) measurements. There were significant correlations between AVP and CIMT (r =−0.691, P < 0.001), AVP and FMD (r = 0.514, P < 0.001) and FMD and CIMT (r =−0.530, P < 0.001). Conclusions: The transthoracic echocardiographic determination of the color M‐mode propagation velocity of the descending aorta is a simple practical method and correlates well with the presence of carotid and coronary atherosclerosis and brachial endothelial function.

Prevalence of gastroesophageal reflux disease in patients with asthma and chronic obstructive pulmonary disease

Background and Aim: It is speculated that the prevalence of gastroesophageal reflux disease (GERD) might increase with asthma or chronic obstructive pulmonary disease (COPD). The aim of the present study was to evaluate the prevalence of GERD in patients with asthma and COPD in an area representative of developing countries. Methods: A validated GERD questionnaire was conducted face‐to‐face with 308 consecutive asthma (240 women) and 133 COPD (35 women) patients in the tertiary referral pulmonary outpatient clinic, and 694 controls from the research area. Detailed histories of patients and pulmonary function tests were also recorded. Results: The prevalence of GERD (heartburn/regurgitation once a week or more) was 25.4%, 17.0%, 19.4% and occasional symptoms (less than weekly) were 21.2%, 16.3% and 27.0% of patients with asthma, COPD and controls, respectively. The prevalence was higher in the asthma group compared with the controls and the COPD group. No significant difference was found between the COPD group and the controls. Heartburn started following pulmonary disease in 24.1% of the asthma group, and 26.4% of the COPD group. The majority of additional symptoms were significantly higher in asthmatics compared with the controls. No difference was found in the consumption of pulmonary medications in asthmatic patients in groups with different symptom frequency. Heartburn was increased 13.8% by the consumption of inhaler medications. Conclusions: These results implicate that the prevalence of GERD in asthma and COPD are lower than in published reports in a tertiary referral center. These differences might be related to the characteristics of developing countries, increased consumption of powerful medications in GERD and pulmonary diseases, or methodological flaws in earlier studies.     

Increased Serum Levels of Epidermal Growth Factor in Children with Autism

The etiology of autism is unclear, however autism is considered as a multifactorial disorder that is influenced by neurological, environmental, immunological and genetic factors. Growth factors, including epidermal growth factor (EGF), play an important role in the celluler proliferation and the differentiation of the central and peripheral nervous system. In this study we hypothesized that EGF may play a role in the pathophysiology of autism and examined serum EGF levels in children with autism. We measured serum levels of EGF in the 27 autistic children and 28 age- matched normal controls. The serum levels of EGF in the subjects with autism were significantly higher than those of normal control subjects. However, there were no correlations between serum EGF levels and clinical variables in the subjects with autism. This is the first report demonstrating the increased serum levels of EGF in children with autism. This study suggests that increased levels of EGF might have an importance in the pathophysiology of autism.     

Correlation of estrogen beta-receptor messenger RNA with endogenous levels of plasma estradiol and progesterone in the female rat hypothalamus,the bed nucleus of stria terminalis and the medial amygdala

Estrogen receptor beta (ERbeta) has been previously mapped in the rat central nervous system. This study aims to explore the regulation of ERbeta mRNA as it is expressed in the intact and cycling female rat brain. Young adult female rats (90+ day, N=20) were screened for estrous phases via vaginal cytology and sacrificed. Brains and blood were collected and processed for in situ hybridization and estradiol (E2) and progesterone (P4) hormone assays, respectively. ERbeta mRNA levels exhibited significant correlations with ovarian steroid ratios (E2/P4) in various brain regions, including the bed nucleus of stria terminalis, the medial nucleus of amygdala, and the anteroventral periventricular nuclei but not the paraventricular and the supraoptic nuclei or the preoptic area of the hypothalamus. No regulatory changes were detected in the cortex. Specifically, in the affected regions, higher P4 levels were significantly correlated with higher ERbeta mRNA expression. In contrast, there was a tendency for higher E2 levels to be correlated with lower ERbeta mRNA expression, but this tendency reached significance only in the bed nucleus of stria terminalis. These results suggest that ERbeta mRNA is regulated in the intact and cycling female rat hypothalamic as well as extrahypothalamic brain regions, and the circulating ovarian hormones play a critical role.     

Follicular dendritic cell sarcoma of the tonsil: case report

Follicular dendritic cell sarcomas are unusual, and extranodal origin is extremely rare. The English literature contains only eight cases in which this sarcoma has been presented as a tonsillar mass. We report a new case of follicular dendritic cell sarcoma of the tonsil in a 76 year old woman. The patient underwent diagnostic tonsillectomy for a left tonsillar mass, and follicular dendritic cell sarcoma was diagnosed based on histopathological and immunoperoxidase findings. Postoperative radiotherapy was performed. The patient is alive and disease-free at 4 years of follow-up. Without a high index of suspicion, this entity can easily be missed. We believe that follicular dendritic cell sarcoma should be included in the differential diagnosis for any tonsillar mass.     

Surgical treatment of hepatic hydatic disease during pregnancy: report of two cases

Current treatment options for hepatic hydatid disease include surgery, medical treatment, and percutaneous drainage. However, the choice between these treatment modalities for pregnant women is still controversial. We reported in this article two pregnant patients with hepatic hydatid cysts who underwent surgical treatment.     

Reconstruction of the middle cerebral artery after excision of a giant fusiform aneurysm

A patient with a giant fusiform aneurysm of the left inferior trunkus of the middle cerebral artery (MCA) is presented. The size of the aneurysm was 5 cm at its largest diameter. Retrograde flow was well developed. After the application of temporary clips the aneurysm was excised and microsurgical reconstructions were undertaken. Adequate flow in the reconstructed MCA trunkus was maintained. This rare case is discussed in the light of the literature.     

Comparison of the factors that influence obesity prevalence in three district municipalities of the same city with different socioeconomical status: a survey analysis in an urban Turkish population

BACKGROUND: To evaluate the obesity status, factors and comorbidities related to it in three district municipalities (DM) that compose city center of Bursa with inhabitants of different socioeconomic status. METHODS: A total of 1632 inhabitants >/=18 years of age were interviewed. The number of sample in each DM was obtained proportional to their populations by stratified sampling method. Among 1632, a total of 1543 subjects were included by random sampling and a questionnaire was filled in including demographic, social and behavioral features. RESULTS: The participants living in DM with the highest socioeconomical status (SES) score and level of education had the lowest body mass index (BMI) and body fat percentage (%BF) compared to other DMs. The lowest obesity prevalence (30.8% vs. 36.4% and 39.3%) in that DM was possibly due to younger age, lower female ratio, more active professional, higher percentage of smoking, more consumption of vegetables, olive or corn oil, and less carbohydrate. For the evaluation of the factors that may influence obesity risk, we investigated the effects of these factors in men and women separately with logistic regression model. Sedentary life style and dyslipidemia (DL) in men, being unemployed, having lower level of education and having hypertension (HT) in women and familial obesity in both gender were found to be related to increased obesity risk. CONCLUSIONS: The prevalence of obesity in Bursa is increasing although inhabitants are taking some precautions parallel to their socioeconomical and educational levels. Obesity is becoming a more alarming public health problem in Bursa and Turkey like in most other parts of the world, which forces us to invent new prevention policies. Besides, the results of our study highlight the fact that especially female education requires more attention for decreasing obesity prevalence in coming generations.
