Background and aims: Many workers face significant hazardous workplace exposures, especially indeveloping countries. The objective of this study was to investigate the prevalence of occupational riskfactors and common occupational diseases in Kerman.Methods: This study was based on data from occupational risk factor and disease monitoring systemsavailable at Kerman Provi...

fine needle aspiration (fna) technique is a well-known procedure in the diagnosis of various organ diseases. this study was conducted to evaluate the utility of fna in the dianosis of neck masses. fine needle aspiration was performed upon 123 patients with palpable nonthyroidal lesions at neck during a five-year period. in ten cases, fna findings were nondiagnostic. from the reminder 113 patien...

Background: Needle stick injuries (NSI) are one of the dreaded but preventable occupational hazard posed to health care worker in various clinical settings. The causes NSI includes caused by use hypodermic needles, blood collection needles intravenous delivery systems, diagnostic aspiration procedures and needle interventional or surgical procedures. In developing countries, prevalence is also ...

OBJECTIVES It is known that a great extent of radiation is emitted from the medical instruments used in hospitals and that radiation exposure can cause thyroid cancer. However, the correlation between occupational radiation exposure in hospitals and thyroid disease is not extensively recognized. METHODS The subjects of the study were female nurses, who worked at a single hospital and female, ...

introduction:foreign body aspiration is usually a serious condition that is most common among the pediatric population, and rare in adults. in adults, aspiration may be tolerated for a long time.case reports:our first case is a 38-year-old man who presented with a 2-day history of swallowing a foreign body. he was completely asymptomatic. chest x-ray revealed the presence of 5-cm foreign object...

BACKGROUND Fire-eater's pneumonia is an exogenous chemical pneumonitis after accidental aspiration of hydrocarbon fluids during the act of fire-eating. There have been few case reports in the literature regarding complications after fire-eating but so far none, to the best of our knowledge, have described such drastic and life-threatening pulmonary complications as in this case while only havin...

Background: Good cytological sample is very important for the cytological diagnosis of thyroid nodules. The aim of this study was to evaluate the adequacy of prepared samples by the combination of aspiration and non- aspiration fine needle biopsy. Methods: In this descriptive – analytical study, sampling was done simultaneously for each patient in fine needle aspiration and non-aspiration biops...

Introduction: Foreign-body aspiration is still considered one of the most important diagnostic and therapeutic issues for physicians. Mortality rates and the prevalence of diseases caused by foreign bodies in the airway are higher in children because of the relatively narrow airway and immature protective mechanisms. The aim of this study was to study the pattern of foreign-body aspiration in t...

This work investigates the use of computational fluid dynamics (CFD) to model air flow and particle transport associated with an inhaling anatomical mannequin. The studied condition is typically representative of occupational velocities (Re = 1920) and at-rest breathing (R = U(o)/U(m) = 0.11). Methods to verify and validate CFD simulations are detailed to demonstrate convergence and describe th...
