Birth defects risk associated with maternal sport fish consumption: potential effect modification by sex of offspring 总被引:2,自引:0,他引:2
Mendola P Robinson LK Buck GM Druschel CM Fitzgerald EF Sever LE Vena JE 《Environmental research》2005,97(2):134-141
Contaminated sport fish consumption may result in exposure to various reproductive and developmental toxicants, including pesticides and other suspected endocrine disruptors. We investigated the relation between maternal sport fish meals and risk of major birth defects among infants born to members of the New York State (NYS) Angler Cohort between 1986 and 1991 (n=2237 births). Birth defects (n=125 cases) were ascertained from both newborn medical records and the NYS Congenital Malformations Registry. For sport fish meals eaten during pregnancy, the odds ratio (OR) for all major malformations combined was slightly elevated for < or =1 meal/month (OR=1.26, 95% confidence interval (CI): 0.84, 1.89) and > or =2 meals/month (OR=1.51, CI=0.74, 3.09), with no meals during pregnancy as the reference category. Higher ORs were consistently observed among male offspring compared with females. For > or =2 meals/month, the risk for males was significantly elevated (males: OR=3.01, CI: 1.2, 7.5; females: OR=0.73, CI: 0.2, 2.4). Exposure during pregnancy and effect modification by infants sex could be important considerations for future studies of birth outcomes associated with endocrine disruptors. 相似文献

Rofecoxib is a selective cyclooxygenase-2 inhibitor that reduces pain and inflammation without inhibiting platelet function. We examined its effects on effort-dependent pain, postoperative morphine requirements, and pulmonary function in 48 patients recovering from open abdominal surgery. Spirometric measurement of forced expiratory volume(1) and vital capacity (FVC) were assessed preoperatively. One hour before the induction of a standardized general anesthetic, patients were given either placebo oral suspension (Group A), or rofecoxib oral suspension (25 mg [Group B] or 50 mg [Group C]) in a double-blinded manner. Postoperative pain control was provided with IV morphine in the postanesthesia care unit and IV-patient-controlled analgesia morphine on the patient care unit. Morphine dose, pain intensity at rest, and pain after respiratory effort (postoperative spirometry) were assessed at 12 and 24 h after study drug administration. The patient-controlled analgesia morphine dose at 24 h was reduced 44% in Group B (30.3 +/- 17.5 mg) and 59% in Group C (22.1 +/- 16.5 mg) versus Group A (53.7 +/- 31.1 mg); P < 0.01 (A versus B). At 12 h, pain scores at rest and after spirometry were lower in Groups B and C than in A (P < 0.05). At 24 h, resting pain scores were lowest in Group C (P < 0.05). Twelve-hour FVC was best preserved in Group C (P < 0.03). There were no inter-group differences in adverse effects or perioperative blood loss. Rofecoxib oral suspension provided a morphine-sparing effect, as well as improvements in pain control and 12-h FVC in patients recovering from open abdominal surgery. IMPLICATIONS: Rofecoxib belongs to class of analgesics known as cyclooxygenase-2 inhibitors that reduce pain and inflammation with less risk of bleeding than standard nonsteroidal antiinflammatory drugs. We found that patients treated with rofecoxib 25 or 50 mg before open abdominal surgery required less IV morphine during the first day of recovery. Despite reductions in morphine requirements, rofecoxib-treated patients reported lower pain intensity scores at rest and after a vigorous cough. In the 50-mg group, improvements in pain control correlated with greater preservation of baseline cough effectiveness (vital capacity) at 12 h. These findings may offer clinical advantages in patients with preexisting pulmonary disease. 相似文献

Surgery for tumors in the abdomen, retroperitoneum, and pelvis requires technical skills and expertise sometimes beyond the capability of a single surgeon. This holds especially true if curative tumor resection involves replacement of arteries and veins, which needs careful planning to avoid long periods of ischemia, and the selection and provision of vascular substitutes according to anatomical position, postsurgical therapy, and adjuncts to avoid thrombosis and infection of vascular grafts. Since the works of Fortner, the value of close collaboration between general and vascular surgeons has been demonstrated, but many of the former even today continue to attempt the operation alone, although the result is not always a masterpiece. The authors refer to their experience in major tumor surgery in either the single management of vascular complications or collaboration. The potential value of close collaboration is presented by negative examples, and a plea is made for a less "eminence"-based management of these sometimes difficult cases, which is based on vast positive experience with vascular diseases of the aorta and the visceral and iliac arteries and veins, including safety measures and adjuncts. 相似文献

Late postoperative opacification of MemoryLens hydrophilic acrylic intraocular lenses: case series and review 总被引:2,自引:0,他引:2
Tehrani M Mamalis N Wallin T Dick HB Stoffelns BM Olson R Fry LL Clifford WS 《Journal of cataract and refractive surgery》2004,30(1):115-122
PURPOSE: To report clinical and spectrographic analyses of 2 explanted hydrophilic acrylic intraocular lenses (IOLs). SETTING: John A. Moran Eye Center, Salt Lake City, Utah, USA, and Johannes Gutenberg-University, Department of Ophthalmology, Mainz, Germany. METHODS: We report 6 cases of opacification of MemoryLens IOLs (Ciba Vision) that occurred approximately 2 years after implantation. The anterior and posterior surfaces of the IOLs had a white, frosted appearance, and the IOLs' interior looked brown, similar to the appearance of a brunescent cataract. Two of the IOLs were explanted because of a significant decrease in visual acuity. The IOLs were sent for further clinicopathologic analysis including scanning electron microscopy and energy dispersive x-ray spectroscopy (EDX). RESULTS: Microscopic analysis revealed multiple, fine, granular deposits of various sizes on the surface of the lens optics. The EDX analysis showed the presence of calcium within the deposits. CONCLUSIONS: Our cases show that hydrophilic acrylic IOLs can opacify even years after implantation. Analysis of the explanted IOLs revealed calcification. 相似文献

Multiple primary soft tissue sarcomas 总被引:1,自引:0,他引:1
BACKGROUND: The synchronous or metachronous development of multiple primary soft tissue sarcomas (STS) of different histopathology has been reported only in isolated case reports. METHODS: The records of patients who developed multiple primary STS and who were treated at a tertiary cancer center between 1982 and 2003 were reviewed. RESULTS: Nine patients with multiple primary STS were identified, representing 0.2% of all patients who were treated for STS. The median age of patients at the time of initial presentation with sarcoma was 60 years (range, 51-81 years). Most patients in this series (n = 7) had metachronous development of a second primary STS. The incidence of second primary sarcomas in patients who were diagnosed previously with STS (4.0 per 10,000 population per year) was significantly greater than the incidence of primary STS in the general population (3.2 per 100,000 population per year; P < 0.01). CONCLUSIONS: Although it is an uncommon occurrence, patients who have a history of STS are at an increased risk for the development of a second primary STS. 相似文献
