Oxidative Stress Parameters, Selenium Levels, DNA Damage, and Phthalate Levels in Plastic Workers.

Di(2-ethylhexyl)phthalate (DEHP) is the most widely used phthalate. DEHP is highly used in PVC floorings and PVC windows and carpeting. The objective of this study was to determine sex hormone levels, oxidative stress parameters, selenium levels, DNA damage, and phthalate levels in plastics workers (n = 24, age = 20-58 years) working in the production of rubber mechanical goods and exposed to DEHP in workplace.

Evaluation of Erectile Dysfunction and Left Ventricular Diastolic Parameters in Lead Exposed Workers.

Background: Lead exposure causes a wide range of vascular diseases through oxidative stress, sympathetic hyperactivity and impairment in nitric oxide bioavailability. In this study, the association between the effects of lead exposure on left ventricular diastolic indices and erectile function were assessed.

Methods: A total of 94 lead-exposed workers without known cardiovascular diseases or risk factors and 30 healthy subjects were enrolled.

A new potential biomarker in early diagnosis of firefighter lung function impairment: dynamic thiol/disulphide homeostasis.

Objectives: The aim of this study was to investigate the associations between urinary arsenic, oxidative stress, assessed by thiol/disulphide homeostasis, and lung diseases in firefighters.

Methods: The study conducted among the municipality-based male firefighters (n = 100) who were admitted to occupational diseases clinic for periodic medical examination. The control group consisted of non-exposed male office workers (n = 50).

Effects of Occupational Silica Exposure on OXIDATIVE Stress and Immune System Parameters in Ceramic Workers in TURKEY.

Silica is the second most common element after oxygen, and therefore, exposures to crystalline silica dust occur in a large variety of occupations such as metal foundries, constructions, and ceramic, quarry, and pottery industries. Since crystalline silica exposure has been linked with silicosis, lung cancer, and other pulmonary diseases, adverse effect attributed to this element has be a cause for concern worldwide. Silica dust exposure in workers is still considered to be important health problem especially in developing countries.

Comparison of European Standard Patch Test Results of 330 Patients from an Occupational Diseases Hospital.

Contact dermatitis (CD) is the most prevalent occupational skin disease with a significant impact on quality of life. Patch testing is used for the identification of responsible allergens which may improve protective and preventive measures in the workplace. Herein, we aim to identify the demographic characteristics and occupation of patients with early diagnosis of occupational CD and compare patch test results.

The Effects of Lead Exposure on Serum Uric Acid and Hyperuricemia in Young Adult Workers: A Cross-sectional Controlled Study.

Objectives: This study aims to evaluate the relationship between serum uric acid levels and renal functions in asymptomatic subjects who had occupational lead exposure, particularly for shorter durations whereby saturnine gout has also been discussed.

Patients And Methods: In this retrospective study, files of 100 males (mean age 34.5±5.

Evaluation of bone mineral density and 25-hydroxyvitamin D levels in subjects with silica exposure.

Objective: The purpose of the study was to evaluate the bone mineral density (BMD) and 25-hydroxyvitamin D (25(OH)D) levels in patients with silica exposure.

Materials And Methods: The study included 104 male subjects with silica exposure and 36 healthy subjects. Posterior-anterior radiographs were classified according to the International Labour Office (ILO) Classification.

Ultrasonographic measurement of the femoral cartilage thickness in patients with occupational lead exposure.

The objective of the present study is to compare distal femoral cartilage thicknesses of patients with occupational lead exposure with those of healthy subjects by using ultrasonography. A total of 48 male workers (a mean age of 34.8±6.

Prolactin levels in manganese-exposed male welders.

Purpose: Early studies on manganese (Mn) exposure have demonstrated that this transition metal affects dopamine neurotransmission. Dopamine serves as a tonic inhibitor of prolactin release in the anterior hypophysis. Our aim was to determine the relation between serum prolactin levels and manganese-exposure.

8-hydroxydeoxyguanosine as a useful marker for determining the severity of trichloroethylene exposure.

The aim of this study was to determine 8-hydroxydeoxyguanosine (8-OH-dG) levels in trichloroethylene (TCE)-exposed workers. Oxidative stress biomarkers and biochemical parameters were monitored among 26 TCE-exposed workers and 78 age-matched control subjects. Levels of urinary 8-OH-dG were analyzed by liquid chromatography tandem mass spectrometry.

Aggravated neuromuscular symptoms of mercury exposure from dental amalgam fillings.

Dental amalgam fillings are widely used all over the world. However, their mercury content can lead to various side effects and clinical problems. Acute or chronic mercury exposure can cause several side effects on the central nerve system, renal and hepatic functions, immune system, fetal development and it can play a role on exacerbation of neuromuscular diseases.

Farewell to an old friend: chest X-ray vs high-resolution computed tomography in welders' lung disease.

Introduction: Welder's lung disease originated from a mixed exposure to different kinds of metals and chemicals from welding fumes. Because of these various harmful effects, irreversible morphological changes may occur in all parts of the respiratory tract, airways and lung parenchyma. Parenchymal changes are the main lesions that define the severity of exposure.

Lead exposure is a risk for worsening bone mineral density in middle-aged male workers.

Objective: Lead exposure linked to osteoporosis in women. However, there is no direct evidence whether lead exposure has effects on bone metabolism in middle-aged male subjects. Therefore, the present study investigated the relationship between bone mineral densitometry measurements, bone markers, endocrine hormones and blood lead levels.

Arsenic exposure associated with decreased bone mineralization in male.

Objective: Arsenic (As) exposure may cause several medical problems. There were a few studies investigated whether it has affected bone tissue in women. However, there was no study in men.

Exposure to mercury among dental health workers in Turkey: correlation with amalgam work and own fillings.

Purpose: To investigate the current status of exposure to mercury (Hg) among dental health workers in Turkey.

Methods: A total of 115 persons working in the same hospital were included in the study and were divided into three groups. Group 1 consisted of 67 dentists; group 2 consisted of 21 dental personnel who work with amalgam, and group 3 consisted of 27 control subjects who work in the same hospital but are non-dental personnel.

Acute mercury poisoning among children in two provinces of Turkey.

Elemental mercury exposure occurs frequently and is potentially a toxic, particularly in children. Children are often attracted to elemental mercury because of its color, density, and tendency to form beads. Clinical manifestations of elemental mercury intoxication vary depending on its form, concentration, route of ingestion, and the duration of exposure.

Analysis of the hematological and biochemical parameters related to lead intoxication.

In parallel with industrial advancements, number of the occupational diseases secondary to chemical exposure is increasing. The chemical agents in the work places affect various organ and tissue systems, leading to chronic diseases. In this study, the cases diagnosed with occupational disease due to exposure to lead were studied and importance of the environmental forensic sciences on this issue was emphasized.

Sialic acid levels in the blood in pregnant women with impaired glucose tolerance test.

Purpose: Gestational diabetes (GDM) is a metabolic disease characterized by the impairment of glucose tolerance during pregnancy. Sialic acid (SA) is a component of glycolipid and glycoproteins found in hormone and enzymes in serum and tissues and high serum SA levels are observed in diabetic patients.

Methods: Serum SA levels were investigated in three groups, namely 61 normal pregnant women with normal 50 gr glucose loading test (group 1: gr 1), 36 patients with high 50 gr test values and normal 100 gr test (group 2: gr 2: group with impaired glucose tolerance test, IGT), and 8 patients with diagnosis of GDM (group 3:gr 3).
