Tracking down the footprints of bad paternal relationships in dissociative disorders: A diffusion tensor imaging study.

Preclinical studies indicate that stress early in life can cause long-term alterations in brain development. Studies have shown alterations in the brain functions of patients after experiencing trauma. Our aim is to examine whether the integrity of white matter tracts might be affected in dissociative disorder (DD) patients. A total of 15 DD patients and 15 healthy controls were studied, with the groups matched by age and gender. Diffusion-weighted echoplanar brain images were obtained using a 1.5 Tesla magnetic resonance imaging scanner. Regions of interest were manually placed on directional maps based on principal anisotropy. Apparent diffusion coefficient and fractional anisotropy (FA) values of white matter were measured bilaterally in the anterior corona radiata (ACR) and by diffusion tensor imaging in the genu and splenium of the corpus callosum. Significantly lower FA values were observed in the right ACR of DD patients versus healthy individuals. We also found an association between bad paternal relationships and lower FA in the genu of the corpus callosum in female patients. Alterations in the right ACR suggest that diffusion anisotropy measurement can be used as a quantitative biomarker for DD. Paternal relationships may also affect the brain's microstructure in women with DD.

Diffusion-weighted MRI of the testes in patients with varicocele: a preliminary study.

OBJECTIVE: This preliminary study aimed to evaluate changes in apparent diffusion coefficient (ADC) values of the testes in patients presenting with varicocele. SUBJECTS AND METHODS: This cross-sectional study included 25 consecutively recruited patients with varicocele and 25 healthy control volunteers. The ADC values were measured in all participants. Kolmogorov-Smirnov tests were used to test the normality of the data distributions, and the data were expressed as arithmetic means and SDs. A one-way analysis of variance with a post hoc Bonferroni test was used to analyze normally distributed continuous data. Independent sample Student t tests were used to compare continuous variables between two groups. Furthermore, a Pearson correlation coefficient analysis was used to examine the association of venous diameters with mean ADC values in patients with varicocele. A two-sided p value < 0.05 was considered statistically significant. Sensitivities, specificities, and areas under the curve were calculated for the ADC values. RESULTS: The ADC values associated with the ipsilateral testicular parenchyma of patients with varicocele were found to be lower than those of healthy volunteers. Moreover, the ADC values of the contralateral testicular parenchyma in patients with varicocele were also lower than those of healthy volunteers. The sensitivity and specificity of ADC values were 90% and 96%, respectively, for patients with varicocele and 89.5% and 96% for healthy volunteers. The mean ADC values were significantly negatively correlated with venous diameter. CONCLUSION: The measurement of testicular ADC values may be used as a diagnostic indicator in the detection of testicular fibrosis.

Joubert syndrome: the clinical and radiological findings.

Joubert syndrome is a rare disease characterised by clinical and radiological findings. Among the classic clinical findings of JS are hypotonia, ataxia, mental-motor retardation, respiratory and opthalmological findings. The paediatric cases included in the study comprised nine patients. There was familial consanguinty in seven cases. Clinically, all cases had mental-motor retardation and hypotonia. Episodic hyperpnoea attacks were observed in one case. Facial dysmorphism was the most common additional systemic anomaly and four cases had additional opthalmic findings. Brain MRI examination revealed that all cases had molar tooth sign, bat-wing appearance and vermian cleft. The majority of cases also had vermian hypoplasia. Cerebellar folial disorganisation was observed in approxiamtely half of the cases. Three cases had corpus callosum anomaly and atretic occipital encephalocoele. No pathology was determined in other organs. This study aimed to evaluate the clinical and radiological findings of 9 patients diagnosed with Joubert syndrome.

Association of parity with osteoprotegerin levels and atherosclerosis.

PURPOSE: Association of serum osteoprotegerin (OPG) levels and cardiovascular disorders has been shown previously. The aim of this observational study was to investigate the relationship between parity, OPG and carotid intima-media thickness (CIMT) in premenopausal women. METHODS: A total of 128 women (mean age ± SD, 37.8 ± 4.7 years) were divided into three group according to parity [1-3 as group 1 (n = 41), 4-6 as group 2 (n = 55) and ≥7 as group 3 (n = 32)]. Serum OPG was measured and CIMT was evaluated. RESULTS: Both serum OPG levels and CIMT tended to increase with advancing parity; OPG level was significantly higher in group 3 than in group 1 (p = 0.013) and CIMT was significantly higher in group 2 and group 3 than in group 1 (p < 0.001 for both). In correlation analyses, there were significant correlations between all three parameters. CONCLUSIONS: Our results revealed that there was an increased risk of cardiovascular disease in women with multiparity. Significant association of OPG with CIMT suggested that OPG might play a role in the pathogenesis of parity-induced atherosclerosis.

Association of serum amyloid A with subclinical atherosclerosis in women with gestational diabetes.

The aim of our study was to evaluate serum amyloid A (SAA), an acute phase reactant, and carotid intima-media thickness (CIMT) as a valid predictor of atherosclerosis in women with gestational diabetes mellitus (GDM). Serum samples from 39 pregnant women with GDM and 25 healthy pregnant women were collected for the analysis of SAA. CIMT was measured in both groups to evaluate future atherosclerotic heart disease risk. The SAA level was measured with ELISA. The mean arterial blood pressure (MABP), CIMT and SAA levels were significantly higher in women with GDM compared with healthy pregnant controls (p = 0.033, p = 0.001 and p = 0.004, respectively). There were significant correlations between SAA and age, BMI, MABP, 50-g oral glucose tolerance test (OGTT), and A1c (p = 0.048, p = 0.037, p = 0.035, p = 0.042 and p = 0.048, respectively) and between CIMT and BMI, MABP, and 50-g OGTT, (p = 0.001, p = 0.004 and p < 0.001, respectively) in correlation analysis. Furthermore, there was a correlation between SAA and CIMT (p = 0.048). Increased SAA and CIMT values in GDM compared with healthy controls might indicate an increased risk of subclinical atherosclerosis and future atherosclerotic heart disease and the importance of inflammation in this process. These changes were associated with obesity, hypertension and glucose intolerance-related factors (BMI, MABP, and 50-g OGTT), which may be relevant to GDM pathophysiology.

Diffusion-weighted MRI of the testis in hydrocele: a pilot study.

OBJECTIVE: To investigate the effects of increased pressure due to the accumulated fluid around testis in hydrocele on testis diffusion and whether this effect (if any) is correlated with the amount of fluid and duration of hydrocele. PATIENTS AND METHOD: 49 patients with unilateral hydrocele were evaluated by magnetic resonance diffusion-weighted imaging. RESULTS: In the study group, while the apparent diffusion coefficient (ADC) values of the testicles with hydrocele differed significantly before and 3 months after the hydrocelectomy (p = 0.001), the ADC values of the testicles without hydrocele were not statistically different (p = 0.101). There was a significant negative correlation between the ADC values of the testicles with hydrocele and the amount of the liquid aspirated during the hydrocelectomy (r = -0.615, p = 0.001). There was no correlation between the ADC values of testis and the duration of hydrocele (r = -287, p = 0.156). This is supported by the findings of the present study of reduced ADC values of testis, meaning reduced diffusion of the testis, with an increasing amount of fluid. CONCLUSION: The pressure of the fluid was suggested to show a mechanical effect that plays an important role in the dysfunction of the testis. The possible dysfunctions of the testicular tissue suggest that they may have a negative effect on fertility.

Evaluation of carotid intima-media thickness, a marker of subclinical atherosclerosis, in children with cerebral palsy.

BACKGROUND: Respiratory and cardiovascular diseases are the most common causes of death in children with cerebral palsy. OBJECTIVE: To evaluate sonographic carotid intima-media thickness, an early marker of atherosclerosis, in children with cerebral palsy and in healthy controls. MATERIALS AND METHODS: One hundred children with cerebral palsy (65 boys), mean age 6.2 (SD, 2.1) years, and 35 age-matched and sex-matched healthy controls were included. Common carotid artery intima-media thickness was measured sonographically. Differences between patients and controls were evaluated with an independent samples t-test. RESULTS: Age, sex distribution and levels of serum lipids were comparable between patients and controls. Average, right and left carotid artery intima-media were thicker in patients compared with controls (mean ± SD, 0.61 ± 0.13 mm vs 0.40 ± 0.03 mm; 0.61 ± 0.14 mm vs 0.40 ± 0.03 mm; 0.61 ± 0.13 mm vs 0.40 ± 0.03 mm, respectively; all P < 0.001). CONCLUSION: Carotid intima-media is sonographically thicker in children with cerebral palsy compared with healthy controls, which may express an increased risk of atherosclerotic diseases.

Evaluation of the future atherosclerotic heart disease with oxidative stress and carotid artery intima media thickness in gestational diabetes mellitus.

BACKGROUND AND OBJECTIVE: In this study our aim was to evaluate paraoxonase (PON1) activity and free sulfhydryl groups (-SH) as antioxidative parameters and lipid hydroperoxide (LOOH) as oxidative parameter in the serum of women with gestational diabetes mellitus (GDM) and determine their relation with the degree of subclinical atherosclerosis. MATERIAL AND METHODS: Serum samples from 39 pregnant women complicated with GDM and 40 healthy pregnant women were collected for the analysis of oxidative markers. Common carotid artery intima media thickness (CIMT) was measured for both groups to assess future atherosclerotic heart disease risk. PON1 activity and -SH were measured spectrophotometrically. LOOH levels were measured by ferrous oxidation with a xylenol orange assay. RESULTS: CIMT and LOOH levels were significantly higher (p = 0.01, p < 0.001, respectively) in GDM group compared to controls, whereas PON1 and -SH levels were significantly lower (p < 0.001 for both). CIMT values were significantly correlated with body mass index (BMI), 50 g oral glucose tolerance test (OGTT), and mean arterial blood pressure (MABP) (p = 0.003, p = 0.02, and p = 0.03, respectively). However, there was no correlation between CIMT and oxidative markers. CONCLUSIONS: Increased levels of LOOH and decreased levels of PON1 and -SH showed disturbance of antioxidative mechanisms in GDM. These changes were associated with increased BMI and MABP which may be relevant to GDM pathophysiology. Furthermore, increased CIMT values in GDM compared to healthy controls designate increased risk of future atherosclerotic heart disease.

Co-occurrence of diaphragmatic and serratus anterior muscle hydatidosis: an unusual localization.

BACKGROUND: With hydatid cyst, the skeletal muscles and diaphragm are rarely affected, and hepatic and pulmonary hydatid cysts are far more common. We report a case with an unusual localization of diaphragmatic and serratus muscle anterior hydatidosis that occurred simultaneously. CASE REPORT: A 37-year-old developmentally disabled woman presented to the Emergency Department (ED) of Harran University with tachycardia, tachypnea, and dyspnea. On pulmonary auscultation, breath sounds were decreased on the right side. A chest X-ray study revealed a radiopaque right hemithorax with a mediastinal shift and tracheal displacement. Thoracic computed tomography scan revealed a hydatid cyst in the serratus muscle anterior and cystic vesicles in the pleural cavity. The patient underwent chest drainage. During drainage, daughter vesicles within the pus were detected macroscopically. An elective thoracotomy was performed after hemodynamic stabilization of the patient. Postoperative chest X-ray study demonstrated that the lungs had re-expanded. The patient had no postoperative complications and was discharged with relief of all symptoms. CONCLUSION: Hydatid cyst should be considered, especially in endemic regions, in the differential diagnosis in the presence of a rare localization or unexpected clinical presentation. Surgical intervention is the appropriate approach for the treatment of hydatid cyst when there is concomitant intrathoracic involvement.

A rare case of petrous apex osteoma.

Osteomas are the most common tumours of the cranial vault and facial skeleton. Temporal bone osteoma is a rare entity. An osteoma arising from the petrous apex is extremely rare. We present a case of osteoma arising from the petrous apex followed by a discussion of the etiology, presentation, and radiologic findings.

Carotid intima-media thickness and paraoxonase activity in patients with ankylosing spondylitis.

PURPOSE: The risk of atherosclerosis is increased in several rheumatological disorders, but any such risk remains unproven for ankylosing spondylitis. Since carotid intima-media thickness is an indicator of early atherosclerosis, and the paraoxonase (PON1) enzyme has antioxidant activity to prevent LDL oxidation, we aimed to identify: 1) the relationship between carotid intima-media thickness (CIMT) and serum paraoxonase (PON1) activity in ankylosing spondylitis (AS) patients; and 2) the possible differences in CIMT in AS patients versus age-matched, healthy controls. METHODS: Forty-five AS patients (36.8±9.8 years, 36 males, 9 females) and 30 controls (35.9±10.2 years, 23 males, 7 females) were recruited consecutively. Serum PON1 activity and CIMT were measured. The Bath Ankylosing Spondylitis Metrology Index (BASMI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Radiologic Index (BASRI) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were used to identify relationships between these clinical indices and levels of CIMT and PON1. RESULTS: Mean CIMT was significantly increased in AS patients relative to controls (0.49±0.06 mm vs. 0.59±0.07 mm; p < 0.0001). Conversely, serum PON1 activity was decreased (199.1±60.3 U/L vs. 96.7±29 U/L; p < 0.0001). PON1 activity was negatively correlated with CIMT (r = -0.557, p = 0.0001). Disease duration was positively correlated with CIMT (r = 0.542, p = 0.0001) and negatively correlated with PON1 (r = -0.649, p = 0.0001). On multivariate analysis, disease duration and serum PON1 activity were found to be independent predictors of CIMT (R2 = 0.687, p = 0.0001). CONCLUSIONS: In conclusion, significantly increased CIMT and decreased PON1 activity suggest a relationship between atherosclerosis and AS: a relationship that is strongly correlated with disease duration.

Paraoxonase-1 is not affected in polycystic ovary syndrome without metabolic syndrome and insulin resistance, but oxidative stress is altered.

Paraoxonase-1 (PON1) activity is decreased in polycystic ovary syndrome (PCOS) having metabolic syndrome (MetS) or insulin resistance (IR). We aimed to assess PON1 activity and oxidative stress in PCOS without MetS or IR. Metabolic and hormonal parameters, high-sensitive C-reactive protein (hs-CRP), oxidative stress parameters (total antioxidant status (TAS), total oxidative stress (TOS), oxidative stress index (OSI), lipid hydroperoxide (LOOH), total free sulfhydryl (--SH) groups), PON and arylesterase were analyzed in 30 normal weighed patients with PCOS without MetS or IR and 20 normal controls. Hs-CRP, PON, arylesterase, and TAS levels of PCOS and control groups were similar. LOOH, TOS, and OSI of PCOS group were higher than in the controls (p < 0.05; p < 0.001, and p < 0.001, respectively). - SH group levels showed a positive correlation with free testosterone (fT). TOS positively correlated with free androgen index (FAI), body mass index (BMI), waist-to-hip ratio (WHR), LOOH, and OSI. This study showed that oxidative stress is increased in PCOS even in the absence of MetS or IR. PON1 activity appears not to be affected in PCOS without MetS and IR. Several metabolic and antropometric risk factors may aggravate this altered oxidative state in PCOS.

Mini-open versus closed reduction in titanium elastic nailing of paediatric femoral shaft fractures: a comparative study.

The purpose of this study is to compare retrospectively intraoperative fluoroscopy time and clinical-radiological results in pediatric femoral shaft fractures treated with titanium elastic nailing (TEN), with a mini-open "blind-hand" technique versus closed reduction. The study included 87 children (18 girls and 69 boys) who underwent surgical treatment with TEN for femoral shaft fractures. Patients were divided into two groups. Group 1 included 42 patients (mean age : 83 +/- 2.7 years) treated with a mini-open "blind-ha nd" technique (a 2-3 cm lateral incision at the level of the fracture ; reduction achieved with one or two fingers, without visualization of the fracture). Group 2 consisted of 45 patients (mean age: 8.8 +/- 2.6 years) treated with a closed reduction technique. Duration of surgery and intraoperative fluoroscopy time were recorded in both groups. Clinical and radiologic results were assessed using the TEN scoring system after mean follow-up periods of 213 +/- 5.8 months and 193 +/- 5.6 months in group 1 and group 2, respectively. Mean duration of surgery was 31.7 +/- 7.6 and 52.1 +/- 14.4 minutes, and mean fluoroscopy time 32.9 +/- 22.1 and 75.1 +/- 31.5 seconds in group 1 and group 2, respectively. Both surgical and fluoroscopy time were significantly longer in group 2 (p < 0.001). There was no significant difference between the two groups in terms of clinical and radiological results. All fractures healed with solid union, and there was no complication that was expected to cause permanent disability. Although successful clinical and radiological results were obtained with both techniques, duration of surgery and intraoperative fluoroscopy time were significantly higher in the closed reduction group 2. We suggest the "blind-hand" technique as an alternative to closed reduction to prevent extensive intraoperative radiation exposure and to decrease the length of the surgical procedure.

An uncommon cause of pneumobilia: blunt abdominal trauma.

Pneumobilia is described as occurrence of free air in the gallbladder or biliary tree. There are a number of causes of pneumobilia, including surgically created biliary enteric fistula, instrumentation of the bile duct on endoscopic retrograde cholangiopancreatography, emphysematous cholecystitis, and pyogenic cholangitis. Pneumobilia has also occurred following blunt abdominal trauma, but to date, no more than five cases of such injury have been reported in the literature. In this report, we present a patient struck by a motor vehicle with traumatic pneumobilia following blunt trauma to the abdomen, which was managed conservatively.

Study of the ureterovesical jet flow by means of dupplex Doppler ultrasonography in patients with residual ureteral stone after extracorporeal shock wave lithotripsy.

The aims of our study are to evaluate ureterovesical jet flow Doppler ultrasound (US) in patients with residual ureteral stone after extracorporeal shock wave lithotripsy (ESWL) and to compare with unobstructed contralateral ureter. Patients who have residual ureteral stone in intravenous pyelography (IVP) and/or computed tomography (CT) after ESWL and unobstructed contralateral ureter in 20 patients were prospectively evaluated with Doppler US. The mean peak velocity of the Doppler waveforms was obtained on the residual ureteral stone and contralateral non-obstructed ureter (17.10 +/- 20), (56.0 +/- 32), respectively (P < 0.05). In conclusion, due to the absence of contraindications and side-effects, Doppler US is sensitive and highly specific that can contribute significantly to the diagnosis of residual ureteral stone after ESWL. It can replace IVP and/or CT, in condition where IVP is undesirable and in addition Doppler US can supply a functional investigation of the obstructed ureter.

Prenatal diagnosis of dicephalic parapagus conjoined twins.

Dicephalic parapagus is a rare anomaly of monochorionic twinning. We present prenatal diagnosis of this anomaly with ultrasonography and magnetic resonance imaging. She was at the 19th week of gestation. Even if earlier diagnosis is possible, this was her first examination unfortunately. Baby had two head and a common trunk. This is one of the rarest twinning. Termination of pregnancy is performed and baby is delivered by cesarean section. Imaging findings of the case are illustrated and discussed with the autopsy findings.

The relationship between carotid intima media thickness and oxidative stress in asthmatic children.

BACKGROUND: Asthma and atherosclerosis are both chronic inflammatory diseases. The progression of the inflammation in asthmatic patients is known to be similar to the increased development of atherosclerosis. OBJECTIVE: The aim of this study was to research the relationship between the difference in carotid intima media thickness (CIMT) and oxidative stress together with difference in CIMT in asthmatic children and control group. METHODS: A total of 84 subjects between 6-15 years of age who had been attending the Pediatric Allergy Unit of the Medical Faculty were included in this study. Asthmatic patients and a control group were evaluated by ultrasonography for measurements of CIMT and oxidative status. RESULTS: In the asthmatic patient group, the CIMT was 0.48 +/- 0.06 mm (right side) and 0.44 +/- 0.05 mm (left side). In the control group it was 0.42 +/- 0.05 mm (right side) and 0.42 +/- 0.04 mm (left side). This difference is statistically significant (p < 0.0001, p = 0.019 respectively). In the asthmatic group a positive correlation was determined between the total oxidant status (TOS) value and the right and left CIMT (p = 0.007, r = 0.44 and p = 0.001, r = 0.50 respectively). CONCLUSIONS: A significant correlation was determined between an increase in oxidative stress and CIMT in asthmatic children. This indicates that atherosclerosis, which is known as an adult disease, may start in childhood. These findings show that it might be beneficial for children who are being followed-up from a diagnosis of asthma to also be evaluated in respect of the development of atherosclerosis.

Concurrence of the tortuosity of bilateral common and left internal carotid arteries in a case with common origin of the innominate trunk and left common carotid artery.

Anatomical variations of carotid arterial system, which are not infrequently encountered, have great impact on the surgical approaches of the neck. Although few reports on common carotid artery tortuosity have been published, no case of symptomatic concurrent common carotid and internal carotid artery tortuosity has been reported. Herein, we report the first case with concurrent common origin of the innominate trunk and left common carotid artery and common and internal carotid artery tortuosity presenting with an oropharyngeal mass.

Pneumoperitoneum, pneumoretroperitoneum and bilateral pneumothorax caused by ERCP.

Endoscopic retrograde cholangiopancreatography (ERCP) is one of the mainstay procedure treatment of hepatobiliary and pancreatic diseases. Life-threatening complications such as pneumoperitoneum, pneumoretroperitoneum, pneumomediastinum, subcutaneous emphysema and pneumothorax related to this procedure rarely occur and only a few cases are reported in English literature. Herein, we report a patient who developed acute abdominal symptoms with subcutaneous emphysema and bilateral pneumothorax due to duodenal perforation, accompaniment of ERCP that was successfuly treated.
