Background
The aim of this study was to conduct a sero-epidemiological survey in Meshkinshahr, Ardabil Province, northwestern Iran to detect the rate of hydatidosis in the city and nearby villages. Literature shows that no such study has been conducted so far.Methods
Overall, 670 serum samples were collected from 194 males and 476 females from patients referred to different health centers of the region. All patients filled out a questionnaire and an informed consent. Sera were analyzed using indirect-ELISA test. Ten µg /ml antigens (Antigen B derived from hydatid cyst fluid), serum dilutions of 1:500 and conjugate anti-human coombs with 1:10000 dilutions were utilized to perform the test. Data analysis was conducted using SPSS software ver. 11.5.Results
The seroprevalence of human hydatidosis was 1.79% by ELISA test in the region. This rate for females was 1.68% and males 2.6%, respectively. There was no significant difference as regards all factors studied and the seropositivity. According to job, farmers and ranchmen had the highest rate of infection as 3.17%. The sero-prevalence of infection was 2.6%% in illiterate people which showed the highest rate. As regards residency, urban life showed no significant difference with rural life (1.1% vs. 2.58%). Age group of 69–90 yr old, with 4.62% as prevalence had the highest rate of positivity.Conclusion
Obtained sero-prevalence of hydatidosis shows more or less a resemblance to other cities of Iran, although due to the specific condition of the city we expected more rate of sero-positivity. 相似文献152.

The sonographic appearance of the endometrium was evaluated in 97 infertile women, 51 from a fertility unit (FU) and 46 from an in vitro fertilization (IVF) program. Three groups of patients were identified: those with normal findings, those with an incomplete endometrial echo, and those without any endometrial echo. Findings were correlated with the type of ovulation induction protocol, the peak estradiol level, and the number of successful pregnancies. In the IVF group, 72% of the patients did not exhibit normal endometrial echoes but had adequate estradiol levels, compared with 62% of the FU patients with normal endometrial echoes but significantly lower estradiol. The data suggest that IVF patients have a nonresponsive endometrium rather than inadequate estrogen stimulation and therefore that an endometrial abnormality may be an important cause of their infertility. Ultrasound may be used as a screening method to identify such patients. 相似文献

Intimal fibromuscular dysplasia and Takayasu arteritis: delayed response to percutaneous transluminal renal angioplasty 总被引:2,自引:0,他引:2
Percutaneous transluminal renal angioplasty has been shown to be an effective technique to dilate renal artery lesions, particularly those due to fibromuscular dysplasia. However, four of 70 patients in this study experienced atypical responses to angioplasty. Their lesions initially resisted dilation and had incomplete dilatation immediately after angioplasty. Long-term follow-up (1 week to 2 years) angiograms, however, demonstrated fully dilated arteries. In cases of focal nonatherosclerotic lesions from intimal or adventitial fibroplasia, initial incomplete dilatation may be satisfactory in the long term whereas repeated inflations may result in undesirable complications. 相似文献

High-dose multi-agent chemotherapy followed by bone marrow ‘rescue’ for malignant astrocytomas of childhood and adolescence 总被引:1,自引:0,他引:1
Jonathan L. Finlay Charles August Roger Packer Robert Zimmerman Leslie Sutton Arno Freid Lucy Rorke Eliel Bayever Naynesh Kamani Eric Kramer Bruce Cohen Beth Sturgill James Nachman Sarah Strandjord Patrick Turski Sharon Frierdich Richard Steeves Manucher Javid 《Journal of neuro-oncology》1990,9(3):239-248
Between April 1986 and March 1989, ten patients under 21 years of age with histologically confirmed malignant astrocytoma,
received marrow-ablative chemotherapy with either thiotepa and Etoposide (five patients) or thiotepa, Etoposide and BCNU (five
patients), followed by bone marrow ‘rescue’. Nine patients had glioblastoma multiforme (GBM), and one patient had an intrinsic
brain stem anaplastic astrocytoma (AA). Seven patients were treated for recurrent tumor. Two patients who developed GBM as
second malignancies were treated directly following surgical resection. One patient had received irradiation only for recently
diagnosed cervical spinal cord GBM.
Thiotepa was administered at a total dose of 600–900 mg/M2 over three days, Etoposide was administered at a total dose of 1500 mg/M2 over three days, and BCNU was administered at a total dose of 600 mg/M2 over four days. Non-hematopoietic toxicities have been mainly transient, predictable and acceptable, consisting of oropharyngeal
mucositis, cutaneous hyperpigmentation, erythema and desquamation.
Four patients achieved complete responses (CR), as determined by radiographic evaluation (CT and/or MRI) on day 28 post-marrow
infusion. The mean remission duration of those with CR is 290 + days; two patients presently remain in remission. Two patients
achieved partial responses (PR, greater than 50% tumor shrinkage) by day 28 post-marrow infusion; both developed disease progression,
at day 61 and 94 post-marrow infusion, respectively. One patient, with a brain stem AA, had stable disease maintained for
13 months post-marrow infusion.
With a total (CR + PR) response rate of 60%, these regimens merit evaluation in broader categories of recurrent brain tumor
patients, as well as in patients with newly-diagnosed GBM. 相似文献
