Within the workplace, there is less reliance on engineering controls for dermal exposure protection and more reliance on the worker's motivation and training in use of personal protective equipment. Behavior thus becomes a significant determinant of dermal exposure, and its assessment paramount in examining and understanding factors influencing exposure. The main objectives of this study were to: (i) assess worker knowledge, attitudes, and perceptions (KAP) of workplace dermal hazards using a self-complete questionnaire and to examine KAP associations with behavior and exposure; (ii) compare worker and manager scores to identify potential gaps in KAP between the two groups; (iii) utilize a semiquantitative observational DeRmal Exposure Assessment Methodology (DREAM) to evaluate worker dermal exposure; and (iv) identify potential behavioral factors underlying exposure using DREAM and KAP. Nineteen industries across the Baltimore, Md. and Lancaster, Pa., regions participated in the study including a total of 89 workers and 17 managers. The scales within the KAP questionnaire that served as the outcome measure included knowledge, training, behavior, behavior beliefs, information beliefs, self-efficacy, and overall beliefs. DREAM scores ranged from 0.15 to 545 with a median of 8 and a mean (SD) of 22 (62.5). Whereas worker self-efficacy with respect to PPE use, and the group "workers with 10-20 years of experience" were marginally positively associated with protective behavior (p < 0.08 and p < 0.06, respectively), a question related to barriers to PPE use was negatively associated with precautionary behavior (p < 0.01). Dermal exposure was positively associated with workers in the age group 40-49 years as compared with those less than 40 years of age (OR = 4.86, 95% CI = 0.93, 25.62). There were no statistically significant associations between KAP and DREAM. This is one of the first studies to begin to elucidate worker knowledge, attitudes, and perceptions that underlie behaviors that lead to occupational dermal exposures. Results of the KAP questionnaire can inform strategies to improve awareness and protective practices in the workplace through factors such as increased worker dermal hazard knowledge, well-informed company PPE selection and availability, and improved worker training. 相似文献

The aim of this study was to investigate the effects of noise on hearing, lipid peroxidation and antioxidant enzymes in textile workers. Thirty textile workers exposed to high noise 105 dB (A) in a textile factory, and 30 healthy male volunteers in our hospital as a control group were included in the study. In both groups, following audiometric tests, blood samples were obtained. In these blood samples, Malonydialdehyte (MDA), Superoxide dismutase (SOD) and Catalase (CAT) levels were investigated. Statistical analysis was performed by using SPSS version 11.0 (SPSS Inc., Chicago 1L) software program. Mean pure tone audiometric thresholds in workers were significantly higher than in control subjects at frequencies 2,000, 4,000 and 6,000 Hz (p<0.05). Hearing losses were more evident at high frequencies (4-6 kHz) than at low frequencies in worker group. (p<0.05). It was observed that textile workers with longer employment duration had poorer hearing threshoulds and the hearing loss had started on those who had worked for 5-8 yr. While MDA levels were significantly higher in workers than controls (p<0.001), CAT activity was significantly lower (p<0.005). Also, SOD activity was lower in workers but difference was not statistically significant. We observed a significant change in hearing threshold of the textile workers compared with that of the control group. Increase in MDA level and decreases in CAT and SOD activities in textile workers, support the opinion that the noise causes the oxidative stress. The fact that noise both causes hearing loss and increases oxidative stress suggests that there may be a relationship between the oxidative stress and hearing loss. But, further studies are needed in order to verify this opinion. 相似文献

Diabetic foot is challenging progressive disease which requires multisystemic control. Neuropathy, arteriopathy, and cellular responses should treated collaboratively. Despite all medical advances, diabetic foot can highly resulted with amputation and also re‐amputation can be required because of failed wound healing. In this study, we aimed to investigate the relation between blood parameters and amputation events. Diabetic 323 patients include to the study who referred to orthopaedic clinic for amputation. Amputation levels (amputation levels phalanx, metatarsal, lisfranc, syme, below knee, knee‐disarticulation, above‐knee amputation) and re‐amputations recorded and compared with routine blood parameters. Re‐amputation was observed at 69 patients. The significant difference detected between lower albumin, higher HbA1c, higher CRP levels (P < 0.05) in regards to gross amputation levels, and increased wound depth. Furthermore, lower albumin levels and higher levels of WBC, HbA1c, CRP, and Creatinine were detected in re‐amputation levels. Especially, HbA1c, CRP, and Creatinine levels were found as upper bound of reference line for re‐amputation. The statistically optimal HbA1c cutoff point for diabetes was ≥7.05%, with a sensitivity of 86% and a specificity of 59%. In according to our results, simple blood parameters can be useful for observing the progress of amputation in diabetic foot. Particularly, lower albumin, and higher HbA1c, CRP, and Creatinine levels detected as related with poor prognosis. Besides, screening of HbA1c level seems to be highly sensitive for detecting of re‐amputation possibility. 相似文献

CONTEXT: Multiple endocrine neoplasia type 1 (MEN1) patients frequently develop Zollinger-Ellison syndrome (ZES). These patients can develop proliferative changes of gastric enterochromaffin-like (ECL) cells and gastric carcinoids (ECL-cell tumors). ECL-cell changes have been extensively studied in sporadic ZES patients and can be precursor lesions of gastric carcinoids, but little is known about factors influencing their severity or development of carcinoids in MEN1/ZES patients. OBJECTIVES: Our objective was to prospectively analyze ECL-cell changes and gastric carcinoids (ECL-cell tumors) in a large series of MEN1/ZES patients to detect risk factors and deduct clinical guidelines. SETTING AND PATIENTS: Fifty-seven consecutive MEN1/ZES patients participated in this prospective study at two tertiary-care research centers. INTERVENTIONS AND OUTCOME MEASURES: Assessment of MEN1, gastric hypersecretion, and gastroscopy with multiple biopsies was done according to a fixed protocol and tumor status. ECL-cell changes and alpha-human chorionic gonadotropin staining were assessed in each biopsy and correlated with clinical, laboratory, and MEN1 features. RESULTS: ECL-cell proliferative changes were universally present, advanced changes in 53% and carcinoids in 23%. Gastric nodules are common and are frequently associated with carcinoids. Patients with high fasting serum gastrin levels, long disease duration, or a strong alpha-human chorionic gonadotropin staining in a biopsy are at higher risk for an advanced ECL-cell lesion and/or gastric carcinoid. CONCLUSIONS: Gastric carcinoids and/or advanced ECL-cell changes are frequent in MEN1/ZES patients, and therefore, regular surveillance gastroscopy with multiple routine biopsies and biopsies of all mucosal lesions are essential. Clinical/laboratory data and biopsy results can be used to identify a subgroup of MEN1/ZES patients with a significantly increased risk for developing gastric carcinoids, allowing development of better surveillance strategies. 相似文献

As the elderly population grows, the problems including skin diseases become more and more frequent. This study involved 300 elderly patients living in 3 nursing homes in Ankara. Their average age was 76.4 years. The average period of time they had lived in the nursing homes was 48.7 months, 25.7% of the cases were bedridden, and 274 cases (91.3%) had at least one systemic disease. Details of the past medical history and the consumed drugs were recorded. The dermatological examination of all cases was performed. Age and sex-dependence of the findings was statistically evaluated, and the risk factors for dermatological diseases were analyzed. The most frequent diseases of the elderly people were: fungal infections and xerosis, with prevalence of 49.7% and 45.3%, respectively. Dermatitis and pruritus were less prevalent (11.0% and 10.3%, respectively). Fungal infections and varicosities were detected more frequently in males, than females. The only risk factor detected for fungal infections was the male sex. We conclude that this study contributes to the identification of the health problems of elderly people, representing a growing proportion of the population in the near future. 相似文献

Obesity and its associated metabolic complications can impair the physiologic regulation of fibrinolysis, leading to a hyper coagulable state. We aimed to assess circulating thrombin activatable fibrinolysis inhibitor (TAFI) levels in obese female patients and to test the effects of orlistat-induced weight loss on basal TAFI concentrations. Obese female outpatients age 18 and older, with a body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) of at least 30, were included into the study. Thirteen nonobese (median BMI, 22.60 kg/m(2)) age-matched females were taken as controls. Plasma TAFI levels were measured before orlistat administration and after 6 months of orlistat treatment in the obese group and only one measurement was done in the control group. Twenty-seven obese patients were recruited into the study. The median TAFI level of the control group was 124.00; this value was significantly lower than the basal TAFI level of the obese group (p < 0.001). TAFI levels after orlistat therapy were statistically significantly lower than basal TAFI levels (p < 0.001) in the obese group. Hemostatic abnormalities including TAFI alterations represent a link between obesity and vascular thrombosis. Effective interventions should be considered in improving the obesity-associated prothrombotic risk profile. 相似文献

Skeletal tuberculosis remains a potentially crippling disease in the developing world; particularly as it usually affects children and young adults. The spine is involved approximately 50% of bone and joint tuberculosis cases. The features of four spinal tuberculosis cases were looked over this article. Their ages were between 18 and 76 years. All of them were male and immunocompetent. Pain was the major complaint. There was no life-threatening neurological sign. Among them, a case who was admitted to the hospital with painful torticollis had upper cervical-lower thoracic spinal tuberculosis with psoas abscesses and peritoneal tuberculosis, but no pulmonary involvement. The other cases had thoracolumbal spinal tuberculosis with psoas abscesses and pulmonary tuberculosis of which miliary, chronic and new pulmonary tuberculosis. The whole diagnosis of spinal tuberculosis was made by radiographically-MRI and CT-. Specific antituberculous therapy with supportive care was begun and remarkable responses without surgical intervention were seen on them except miliary pulmonary tuberculosis case. The aim of this presentation was to emphasize the importance of early diagnosis so that adequate pharmacological treatment can be initiated to avoid serious complication. 相似文献

This study compared the analgesic efficacy of intrathecal (IT) morphine plus IV patient-controlled analgesia (PCA) morphine with IV PCA morphine alone in 33 patients undergoing thoracotomy randomized to two groups: the IT morphine group (n=17) received 10 microg/kg morphine 1 h before the end of surgery, while the control group (n=16) did not. All patients had access to an IV PCA pump post-operatively that delivered 2 mg morphine boluses. Post-operative pain and sedation scores, respiratory and haemodynamic parameters, and morphine demand and delivery were assessed up to 48 h. Post-operative pain scores and morphine consumption were significantly reduced, while peak expiratory flow rates were significantly increased in the IT morphine group compared with controls. We concluded that IT morphine in addition to IV PCA established superior analgesia and maintained better respiratory function compared with IV PCA alone in post-thoracotomy patients. 相似文献

INTRODUCTION: Compression fracture of the vertebral body is common, especially in older adults. Injuries to the spinal column are one of the most frequent injuries by accidents and falls from heights. Vertebral fracture associated with minor trauma, however, is a rare occasion. CASE REPORT: Five cases were injured in the inner city buses after passing onto speed bumps are presented. On presentation, four patients complained of severe pain in the thoracolumbar region, while in the other patient, physical examination revealed pain and tenderness on the neck. No neurologic deficit was noted except for one patient with tenderness on thoracic spines. Examination of the thoracolumbar X-ray and computed tomography displayed compression fractures in four patients. Other laboratory data obtained on admission were within normal limits. Posterior instrumentation was applied to three patients. All patients recovered well except for the one with cervical fracture. CONCLUSION: Drivers should be strongly warned and educated on the potential hazards of traversing past such bumps in roads too fast and such barriers should be built regarding tested standards. 相似文献
