OBJECTIVES: To perform a case-control study of maternal occupational physical activity and risk for orofacial clefts in Texas during 1999-2009. METHODS: We used logistic regression to assess 14 measures of physical activity estimated from a job exposure matrix, using the maternal occupation reported on the birth certificate, among 887 children with cleft lip with or without cleft palate (CLP), 436 children with cleft palate only (CP), and 1932 controls. RESULTS: After adjusting for several potential confounders, seven measures of physical activity (as a categorical and/or continuous variable) were significantly associated with CLP, CP, or both...

INTRODUCTION: Taxi drivers are at high risk for low back pain (LBP). AIM: Identify the association between psychosocial-work factors (Job strain, Iso-strain, effort-reward imbalance [ERI], unfairness, and mental exertion) and LBP in taxi drivers. METHODS: A cross-sectional study was done with 129 taxi drivers. RESULTS: Approximately 63% reported LBP in the prior 12 months. Chi square or t-test analyses identified the associations between demographic, work, health, and psychosocial work factors, and self-report of LBP in the prior 12 months...

We present a case that highlights the difficulties with diagnosis and the dangers of occupational allergic sinusitis and asthma left unrecognized. We describe the case history of a man who experienced work-related symptoms 1 year after beginning work as a cheesemaker at a creamery, and whose respiratory symptoms progressively worsened over 16 years before an occupational cause of his asthma was identified. His initial discrete episodes of sinusitis and acute bronchitis evolved into persistent asthma of increasing severity with exacerbations requiring repeated emergency room treatment...

BACKGROUND: Recent NIOSH publications have focused on the respiratory health of coal miners in central Appalachia, yet 57% of U.S. coal miners work in other regions. We characterized respiratory morbidity in coal miners from these regions. METHODS: Active coal miners working outside of central Appalachia who received chest radiographs and/or spirometry during 2005-2015 were included. Chest radiographs were classified according to International Labour Office standards and spirometry was interpreted using the American Thoracic Society guidelines...

Luz S Marín, Hester Lipscomb, Manuel Cifuentes, Laura Punnett
BACKGROUND: Safety climate, a group-level measure of workers' perceptions regarding management's safety priorities, has been suggested as a key predictor of safety outcomes. However, its relationship with actual injury rates is inconsistent. We posit that safety climate may instead be a parallel outcome of workplace safety practices, rather than a determinant of workers' safety behaviors or outcomes. METHODS: Using a sample of 25 commercial construction companies in Colombia, selected by injury rate stratum (high, medium, low), we examined the relationship between workers' safety climate perceptions and safety management practices (SMPs) reported by safety officers...

This case report presents a 27 year-old manual worker with right wrist extension deficit after pneumatic hammer handling. MRI and electromyographic studies revealed partial compromise of the posterior interosseous nerve (PIN) proximal to the branch for the extensor digitorum communis. The patient enrolled a 6-week rehabilitation period and recovered without remaing symptoms. PIN syndrome has mostly been associated with compressive neuropathies of the upper limb, but has seldom been reported in labor contexts...

BACKGROUND: It has been suggested that asbestos exposure affects lung function, even in the absence of asbestos-related pulmonary interstitial or pleural changes or emphysema. METHODS: We analyzed associations between well-known asbestos-related risk factors, such as individual cumulative asbestos exposure, and key lung function parameters in formerly asbestos-exposed power industry workers (N = 207) with normal CT scans. For this, we excluded participants with emphysema, fibrosis, pleural changes, or any combination of these...

Steven B Markowitz, Jacqueline M Moline
Although most cases of malignant mesothelioma of the pleura are caused by one or more readily recognized sources of exposure to asbestos, cases of the disease with more occult exposure occur, especially since asbestos has been used in over 3,000 products. Dental lining tape contained asbestos from the 1930s until at least the 1970s and was used in the lost wax method of casting crowns, bridges, and other metal dental prosthetic devices. We report six cases of pathology-verified malignant mesothelioma, mostly among dentists, following exposure to airborne dust from asbestos dental tape, which resulted in asbestos tort litigation...

OBJECTIVES: Malignant mesothelioma (MM) is a rare and generally fatal cancer, usually caused by asbestos, although about 5-10% of cases report no asbestos exposure. This study aimed to identify sources whereby people in Western Australia (WA) may be unknowingly exposed to asbestos or to other exposures which may cause MM. METHODS: Cases with no known asbestos exposure were selected from the WA Mesothelioma Register (WAMR). Matched controls were selected from hospital patients admitted for conditions unrelated to asbestos...
