BACKGROUND: This study aimed to investigate whether exposure to sunflower pollen (Helianthus annuus) increases both sensitization and respiratory symptoms, and whether or not it affects lung functions in sunflower processing workers. METHODS: The largest sunflower processing factories in the Thrace region of Turkey participated in this study. Workers from the units directly exposed to sunflower seed enrolled as the study group (n = 102) and workers who were not directly exposed to Helianthus annuus pollen (n = 102) were the control group. Detailed questionnaires covering respiratory and allergic symptoms were completed, and skin prick tests and lung function tests were performed. RESULTS: We found a very high rate (23.5%) of sensitization to Helianthus annuus in the study group compared to the controls (P<0.001). Logistic regression analysis showed that the risk of sensitization to H. annuus was increased 4.7-fold (odds ratio = 4.17, 95%) confidence interval = 1.3-16.7) if subjects were exposed to sunflower pollen in the workplace. While asthmatic symptoms and allergic skin diseases were not different between the two groups, workers in the study group had a higher rate of allergic rhinitis and conjunctivitis (P<0.05). We found that pulmonary function was significantly impaired in the study group (P<0.01). Using a multivariate analysis model, inclusion in the study group was found to be a predictive factor for impairment of lung function (P=0.002). CONCLUSIONS: We conclude that sunflower pollen has high allergenic potential, especially when there is close contact, and exposure to sunflower pollen in the workplace can result in impairment in lung function. 相似文献

Gastric mucosal damaged induced by cold and restraint stress caused increase in gastric lipid peroxidation (LP) and decrease in gastric glutathione levels. Two calcium-channel blockers, verapamil and nicardipine, prevented stress-induced increase in gastric LP, as well as ulcer formation. Both calcium-channel blockers protected against stress-induced ulcers, and inhibition of LP may be among their mechanisms of action.In memory of Dr. Ilker Aykaç whom we have started with. 相似文献

Spinal osteochondromas are very rare, and they present with nonspecific localized pain owing to bone involvement. Diagnosis is made based on direct X-ray and computed tomography (CT) imaging of the exophytic bone lesion with pedunculated or sessile structure. Although asymptomatic patients can be observed, surgical excision is the main treatment modality. We present the case of a 34-year-old man with solitary thoracic osteochondroma. The patient presented with complaints of pain in the legs, numbness, and inability to walk. The diagnosis was confirmed with CT imaging showing calcified heterogeneous bone lesion originating from the left side of T1-2 facet joint. After total excision, histopathological examination revealed the diagnosis of osteochondroma. No new clinical or radiological findings were detected in the 10-month follow-up. 相似文献

Understanding the behaviour of implantable medical devices is of obvious importance. The potential for failure of a medical device can often be associated with issues related to cyclic loading of the device, and material fatigue. Detailed finite element simulations to evaluate the fatigue of stents allow the engineer to assess potential failures. The engineer can then use the analysis results to modify the design and prevent failure, without making and testing numerous physical devices. Complete understanding of the mechanical behaviour of a stent provided by finite element analysis has the benefits of facilitating effective design, helping to reduce time to market and minimising the potential for unwanted failures. 相似文献

Breast cancer is the most common type of malignancy in reproductive-age women. Breast cancer chemotherapy is associated with premature ovarian failure, infertility, and negative psychosocial effects related to these reproductive changes. As a result of this, fertility preservation becomes highly critical in this group of women. Besides the fertility preservation methods that utilize assisted reproductive technologies such as embryo, oocyte, and ovarian tissue cryopreservation, another suggested strategy for fertility preservation is suppression of ovarian ovulatory function by gonadotropin-releasing hormone agonist (GnRHa) administration before and during chemotherapy. However, both the efficacy and safety of GnRH agonists for prevention of ovarian damage are unproven and the preponderance of evidence indicates that this is an ineffective strategy. This review details the most recent information and studies on this controversial topic. 相似文献

Ventricular septal rupture is a serious complication following acute myocardial infarctions and is associated with a significant mortality rate. Classically, two‐dimensional transthoracic echocardiography has been used to diagnose this complication and visualize its location. Two‐dimensional transesophageal echocardiography has supplemented the transthoracic approach by providing more accurate assessment of the defect size and in guiding closure both percutaneously and intraoperatively. This modality, however, is limited to two‐dimensional views only, and a greater breadth of information is instead available through the use of three‐dimensional transesophageal echocardiography. We present a series of 11 patients in which live/real time three‐dimensional transesophageal echocardiography offered incremental benefits over two‐dimensional imaging alone. 相似文献

The comorbidity of post-traumatic stress disorder (PTSD) and drug addiction is quite often overlooked in refugees. However, the simultaneous treatment of both disorders is of elemental importance for a positive outcome in addicted and traumatised refugees. Furthermore, mutual misinterpretations of habits, behaviours and reactions through negligence of the distinct sociocultural context of patient and clinician often leads to unfavourable developments. These observations are exemplified in this case report. 相似文献

Development of secondary amyloidosis is an infrequent complication in patients with Behçet's syndrome (BS). It has been reported that multiple systemic involvement, long disease duration, and male gender are major clinical factors accompanying the development of amyloidosis in BS. We report a case of secondary amyloidosis in a patient diagnosed as having BS with a positive pathergy test 9 years previously and who had isolated mucocutaneous involvement. Regular use of colchicine since the diagnosis and somewhat mild progress of the disease could not prevent the development of secondary amyloidosis in this patient. He is alive and receives hemodialysis regularly. 相似文献
