Implementation of the analytic hierarchy process (AHP) and Fine-Kinney method (FKM) against risk factors to determine the total cost of occupational health and safety precautions in environmental research laboratories.

A risk assessment method provides the definition of the risks that may be encountered in a laboratory. In order to take safety precautions regarding the in environmental research laboratories, risk assessment studies using Analytic Hierarchy Process (AHP) and Fine-Kinney Method (FKM) were carried out in this study. The environmental research laboratories were selected for the occupational health and safety assessment studies which analyze environmental samples such as wastewater, biological sludge, soil/sediment, and solid waste.

Sudden-onset paraplegia during pregnancy caused by haemorrhage in a spinal cord haemangioblastoma: A case report.

Spinal cord haemangioblastomas are rare central nervous systems tumours, and haemorrhage.It is an uncommon occurance. We report a 28-year-old pregnant patient who presented with paraplegia due to acute haemorrhage of a spinal haemangioblastoma.

Congenital Agenesis of Right Internal Carotid Artery: A Report of Two Cases.

Congenital unilateral agenesis of the internal carotid artery (ICA) is a rare anomaly. Due to proper sufficient collateral circulation via the circle of Willis most cases are asymptomatic, but patients can also present with ischemic or hemorrhagic cerebrovascular insults. The absence of the bony carotid canal is essential to differentiate this anomaly from chronic ICA occlusion.

Diffusion-weighted imaging (DWI) of the liver in assessing chronic liver disease: effects of the presence and the degree of ascites on ADC values.

Purpose: The aim of this study was to determine the correlation between the liver and spleen apparent diffusion coefficient (ADC) values of patients with chronic liver disease and the presence and the degree of ascites.

Materials And Method: In this retrospective study, we assessed 107 patients with chronic liver disease and 39 control subjects who underwent upper abdominal MR imaging including echo-planar diffusion-weighted imaging (DWI). Among the 107 cirrhotic patients, 56 were classified as group 1, 25 as group 2, and 26 as group 3 according to the absence, the presence of minimal, and the presence of massive ascites, respectively.

The Assessment of Hepatosteatosis in Living-Donor Liver Transplant: Comparison of Liver Attenuation Index and Histopathologic Results.

Objectives: The purpose of the study was to determine the diagnostic value of computed tomography densitometry in the quantification of hepatosteatosis.

Materials And Methods: Fifty-one potential liver donors, ranging in age from 19 to 52 years (mean age: 32.4 years ± 10.

Effects of acute exercise on the diameter of the spermatic vein, and duration of reflux in patients with varicocele.

Objective: The aim of this study was to investigate the effects of acute exercise on the diameter of the spermatic vein, and on the duration of reflux in patients with varicocele.

Material And Methods: The study included 38 patients with complaints of infertility and scrotal pain between 2009 and 2010. The diagnoses were made by physical examination and colour Doppler ultrasound, with both performed before and after exercise tests.

Synovial chondromatosis of the temporomandibular joint: radiologic and histopathologic findings.

Synovial chondromatosis is a formation of multiple intrasynovial nodules resembling osteochondromas, resulting from proliferative changes in the synovial linings of joints; as the disorder progresses, nodules increasingly withdraw from the intrasynovial areas for the joint cavities. This is a relatively unusual case that can arise at unilateral large joints, such as knee, hip, and elbow, with the temporomandibular joint being the rarest one of them. Early recognition of the signs and symptoms with resultant accurate diagnosis, as well as proper surgical treatment, offers patients the best hope of recovery and improved quality of life.

The role of MRS in the differentiation of benign and malignant soft tissue and bone tumors.

Objective: The aim of our study was to investigate the value of choline in the discrimination of benign and malignant soft tissue and bone tumors.

Materials And Methods: The study group consisted of thirty subjects with bone or soft tissue tumors larger than 1.5 cm in diameter.

Prospective evaluation of the alterations in the morphology and vascular resistance of the renal parenchyma with color Doppler ultrasonography after percutaneous nephrolithotomy.

Purpose: To evaluate the kidneys with color Doppler ultrasonography (CDUS) to determine whether percutaneous nephrolithotomy (PNL) causes renal parenchymal damage.

Patients And Methods: In 24 patients who underwent unilateral PNL with single renal pole access, cortical thickness, echogenicity, and resistive index (RI) were measured in each pole of the operated and contralateral kidney separately before and at postoperative day (POD) 1, and at 3, 6, and 12 months after PNL.

Results: The mean age of the patients was 36.

[Dynamic contrast-enhanced magnetic resonance imaging findings of mass lesions of the pontocerebellar angle].

Objectives: The differential diagnosis of mass lesions of the pontocerebellar angle is not always possible by conventional magnetic resonance imaging (MRI). In this study, we investigated the role of dynamic contrast-enhanced MRI in the differential diagnosis of acoustic neurinoma, meningioma, and paraganglioma.

Patients And Methods: Twelve patients (8 females, 4 males; mean age 47.

1H magnetic resonance spectroscopy of the normal testis: preliminary findings.

Purpose: The purpose of this study was to determine the pre- and postpubertal 1H magnetic resonance spectroscopic characteristics of the normal testis to establish baseline values for further clinical studies.

Materials And Methods: The subjects consisted of male volunteers, of whom 19 were prepubertal with ages between 7 and 13 years and 24 were postpubertal with ages between 19 and 39 years. Their testes were evaluated at 1.

Unilateral reverse ocular bobbing caused by tuberous sclerosis.

A female aged 12 months with developmental delay and left-sided reverse ocular bobbing (rapid deviation of the eye upward and a slow return to the horizontal position) was observed. At birth, an upper left gingival mass, pathologically diagnosed as a benign granular cell tumour, was removed. On computed tomography (CT), left middle cerebral pedincular and midpontine lesions were seen.

Renal interlobar artery parameters with duplex Doppler sonography and correlations with age, plasma renin, and aldosterone levels in healthy children.

Objective: The objectives of this study were to compare and make correlations between age and Doppler parameters of the interlobar arteries, including synchronously obtained plasma renin and aldosterone levels and to obtain new normative data regarding acceleration time in healthy children from neonates to 16 years.

Subjects And Methods: One hundred sixty-nine healthy children (72 girls and 97 boys) were classified into four groups: group 1 (< 1 year; n = 34), group 2 (range, 1-6 years; n = 48), group 3 (range, 6-12 years; n = 50), and group 4 (range, 12-16 years; n = 37). Blood samples from the renin and aldosterone were collected in the morning after bed rest and fasting.

Spontaneous intracranial hypotension with pituitary adenoma.

Spontaneous intracranial hypotension (SIH) is an unusual syndrome that is characterised by positional headache, neck rigidity, nausea and vomiting. The characteristic magnetic resonance imaging (MRI) findings are diffuse smooth pachymeningeal thickening and enhancement, downward displacement of posterior fossa structures and pituitary gland enlargement. An unusual case of SIH with pituitary macro-adenoma and subsequent subdural haemorrhage is presented, and its clinical picture, MRI findings and possible pathophysiological mechanism are discussed.
