Oxidative stress plays an important role in the pathogenesis of some diseases such as lung cancer, chronic obstructive pulmonary disease, and atheroscleorosis. Smoking may enhance oxidative stress not only through the production of reactive oxygen radicals in smoke but also through weakening of the antioxidant defense systems. In this study, we investigated the effects of smoking on lipid peroxidation and paraoxonase activity in a healthy population. The study consisted of (n = 30) smokers and (n = 30) nonsmokers. The age of the population which is studied was 44.74 ± 10.59 yr. The levels of serum malondialdehyde (MDA) and paraoxonase (PON1) activities were measured by the modified Buege method and the Eckerson method, respectively. Student's t-test was used to analyze the data. The serum MDA levels were significantly higher (p < .05) and serum PON1 activities were significantly lower (p < .001) in smokers than in nonsmokers. Thus, increased levels of serum MDA and decreased PON1 activities may be important in determining the oxidant/antioxidant imbalance in smokers. 相似文献

Congenital dermal sinus of the cervical spine in an adult. 总被引:1,自引:0,他引:1

Congenital dermal sinuses are epithelium-lined tracts that extend from an opening in the skin through deeper tissues. Most dorsal congenital dermal sinuses are located in the lumbosacral area; a cervical location is unusual. This report describes a 24-year-old woman who presented with neck pain of 6 months' duration. A dimple in the skin over her cervical spine and a stunted right foot (0.5 cm shorter than the left) were detected on physical assessment. Neurological examination revealed increased deep tendon reflexes in her lower extremities. Magnetic resonance imaging showed a dermal sinus extending from the dimple site to the spinal cord near the C4-C5 vertebrae. Laminectomies were performed at C3-C4 and the tract was totally excised. The patient's neck pain completely resolved and her deep tendon reflexes were normal at 12 months after surgery. Tethered spinal cord alone does not necessarily demand surgery; however, if a congenital dermal sinus is present then surgery is indicated to prevent spinal infection. Even if there are no neurological symptoms, the tract must be surgically removed and the cord must be fully released to prevent future infectious or neurological complications. 相似文献

BACKGROUND: Medical treatment is usually ineffective for Holmes' tremor, and surgery is the treatment of choice for many patients. Here we report the case of a 14-year-old girl who developed Holmes' tremor related to a thalamic abscess and was successfully treated with thalamic deep brain stimulation. CASE REPORT: The patient presented with left hemiparesis and headache and was hospitalized. Investigation revealed a thalamic abscess in the left cerebral hemisphere. The abscess was drained via stereotactic surgery and a course of antibiotic treatment was completed. Four months after treatment, the patient developed Holmes' tremor in her left upper extremity. When attempts at medical treatment with levodopa, clonazepam, and trihexyphenidyl all failed, an implant was placed and deep brain stimulation of the ventral intermediate nucleus of the thalamus was initiated. During 2.5 years of follow-up, her tremor diminished by 90%. CONCLUSION: This case demonstrates that medically resistant Holmes' tremor related to a thalamic lesion can be successfully treated with thalamic deep brain stimulation. 相似文献

Cerebral occurrence of Echinococcus multilocularis is very rare and there is no widely accepted therapeutical method. In this report we present a case with an intracranial mass lesion and a palpable hepatic mass, which appeared to be due to Echinococcus multilocularis in the histopathological examination. 相似文献

BACKGROUND: Complementary and alternative medicine (CAM) is in the spotlight of society. However, what is the position of physicians at this point? OBJECTIVES: To determine general practitioners' (GP) knowledge, attitudes, and approaches to CAM. METHODS: All GPs (n=521) practicing in Bursa Province, Turkey were surveyed by a questionnaire. RESULTS: Responses from 49% of GPs were analyzed. Altogether, most of our physicians (96.5%) had not received any education about CAM, wanted to learn more (74.4%), and their knowledge levels were low (60.8%). About half of them (51%) believed in the efficiency of CAM, whereas 38.0% did not. GPs desire more information about herbal medicine and acupuncture. Only 29% of GPs were using some type of CAM for themselves. CONCLUSIONS: GPs are aware of the subject's importance and want to learn more about CAM and improve their knowledge. It would be reasonable to provide training possibilities for GPs, primarily for the CAM types highly used by the population and most requested by the physicians. 相似文献

Hydatid disease involving the vertebral body and paravertebral soft tissues is rare even in rural areas where echinococcosis
is endemic. The case of a 34-year-old woman with vertebral hydatid disease mimicking tuberculous spondylodiscitis (Pott's
disease) is presented in this report. Spinal hydatid disease should be considered in the differential diagnosis of spondylodiscitis
in endemic countries, and tested for with imaging and serology. 相似文献
