PURPOSE: To determine the effect of socioeconomic factors on quality of life (QoL) after treatment in patients with head and neck carcinoma (HNC). PATIENTS AND METHODS: The study population included 50 HNC patients seen in their control examinations after radiotherapy during a 2-month interval and who were willing to complete the Short-Form 36 QoL questionnaire. Socioeconomic, demographic, and tumor- and treatment-related factors were analyzed for their effect on physical component summary score (PCS) and mental component summary score (MCS) using the Mann-Whitney U test. RESULTS: All patients received radiotherapy, and 33 patients (66%) underwent surgery for the primary tumor and/or neck disease. Chemotherapy was given in 9 patients (18%). Mean PCS and MCS were 47.9 (range, 24.8-59.3) and 46.7 (range, 22-63.3) for the whole patient population. There was no significant factor affecting PCS. Education level of "middle school or higher," perceived economic status of "medium or higher," social security status of not being "absent or minimally covered," and unilateral type of neck surgery were found to increase MCS significantly. According to separate linear regression analyses performed for three socioeconomic variables, the most significant factor for MCS was social security status compared with education level and perceived economic status. It was the only parameter that retained its significance when all five parameters were combined in a linear regression model. CONCLUSION: This study demonstrated that educational status, perceived economic status, and social security status showed a significant effect on the QoL of HNC patients after radiotherapy. When all variables were taken into account, only "social security status" remained significant. 相似文献

The aim of this study was to assess the rates of variant alleles of cytochrome P4501A1 (CYP1A1) in patients with polycystic ovary syndrome (PCOS). It was designed as a case-control study in Hacettepe University, Faculty of Medicine, Department of Obstetrics and Gynecology and Genetics. Forty-eight patients with PCOS served as the study group. Ninety-six regularly cycling women with no clinical and biochemical evidence of hyperandrogenism and polycystic ovary appearance served as the controls. The CYP1A1 variant alleles of all patients were determined via polymerase chain reaction. The rate of the CYP1A1 isoleucine (Ile)/valine (Val) allele was significantly higher in patients with PCOS than in the controls (OR: 7.8, 95% CI: 3.45-17.52, P < 0.001). However, there was no statistically significant difference in the distribution of Val/Val genotype (OR: 4.0, 95% CI: 0.60-26.73). The rate of any Val genotype (Ile/Val or Val/Val) was significantly higher in patients with PCOS compared with the control group (OR: 7.4, 95% CI: 3.33-16.46, P < 0.001). In conclusion, the patients with PCOS had a 7.8-fold higher frequency of CYP1A1 Ile/Val genotype and a 7.4-fold higher frequency of CYP1A1 of any Val genotype (Ile/Val or Val/Val). 相似文献

The objective of this cross-sectional study was to identify the prognostic factors that influence the outcome of ovarian stimulation with intrauterine insemination (IUI) cycles using gonadotrophins in couples with unexplained and mild male-factor subfertility. A total of 838 cycles in 456 women with unexplained and mild male-factor subfertility attending a university-based infertility clinic was evaluated. Of these cycles, 139 resulted in pregnancy (16.6% per cycle) and 96 out of 98 ongoing pregnancies resulted in live term birth. Live birth rate per patient and per cycle was 21.1% and 11.4%, respectively. Multivariate logistic regression analysis demonstrated that duration of infertility (P = 0.034), type of infertility (P = 0.003), aetiology of infertility (P = 0.004), number of treatment cycles (P = 0.0001) and number of dominant follicles before human chorionic gonadotrophin (HCG; P = 0.024) were significant independent factors to predict clinical pregnancy. The duration of infertility (P = 0.043), number of treatment cycles (P = 0.0001) and number of dominant follicles before HCG (P = 0.024) were significant independent factors to predict live birth. In conclusion, for subfertile couples having shorter duration of subfertility, multifollicular response to gonadotrophins and in their first treatment cycle are more likely to succeed a live birth with IUI treatment using recombinant gonadotrophins. 相似文献

Acupuncture, a method of traditional Chinese medicine that uses Back-Shu and Huatuo-Jiaji points, is especially effective for treating diseases of the visceral organs. Applying acupuncture on Back-Shu points affects visceral organs in many ways. For example, it dilates the bronchus, affects the heartbeat, stomach motility, urinary bladder contractions and so on. Acupuncture's effects can be explained as viscero-cutaneous, cutaneo-visceral, cutaneo-muscular, and viscero-muscular reflexes. Segmental dispersion of the sympathetic and parasympathetic systems is related to the location of Back-Shu points. Changes in visceral organs caused by application of acupuncture can be explained as modulation of the sympathetic and parasympathetic systems. 相似文献

In the present study, attempts have been made to determine the effects of honey on intestinal morphology, postoperative adhesions, and the healing of colonic anastomoses in the rats after colonic resection and anastomosis. Thirty-six rats were randomly divided into three groups each including 12 animals. Colonic resection and anastomosis were performed on all animals. Rats were fed with standard rat chow in group I, standard rat chow plus 10 g/kg/day honey in group II and artificial honey including the same caloric amount with honey in group III. Adhesion scores, bursting pressures and histopathological examinations were evaluated. Colonic bursting pressures of honey group were significantly better than control and artificial honey groups. Histological analysis of anastomotic site showed that submucosa and muscularis propria were nearly filled with granulation tissue and regular fibrin matrix in honey group. There was statistically significant difference between the adhesion scores of honey vs artificial honey and control groups. The scores of histological changes of ileum in honey group were significantly different from other groups. These results indicate a protective role of honey against intraabdominal adhesions and anastomotic dehiscence. 相似文献

OBJECTIVE: An endometrioid adenocarcinoma (EAC) with true trophoblastic differentiation is a rare event with a highly aggressive clinical course. CASE: We report an endometrioid adenocarcinoma of the endometrium in which there was a morphologically conventional-appearing EAC component admixed with multinucleated giant cells and large pleomorphic tumor cells that resembled a choriocarcinoma without an elevated serum level of human chorionic gonadotropin (hCG) in a 42-year-old unmarried woman with a history of abnormal uterine bleeding. A total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymph node dissection were performed. Histopathologic study of the specimen showed endometrioid adenocarcinoma extended to the deep myometrium with a focus of hemorrhagic and necrotic tumor composed of multinucleated giant cells, large pleomorphic tumor cells, suggesting choriocarcinomatous differentiation (CD). Immunohistochemical studies demonstrated intense reactivity of tumor cells for human chorionic gonadotropin (hCG) confirming the diagnosis. A complete clinical workup ruled out metastatic spread to the brain, lungs, skeleton, or abdomen. The patient was alive with no evidence of disease 6 months later. CONCLUSION: Although endometrioid adenocarcinoma with choriocarcinomatous differentiation is known to behave in a more aggressive course, this disease may have a good prognosis with a clinically indolent course when it is small, and without elevated serum hCG levels. 相似文献

BACKGROUND: Different ovulation trigger methods such as gonadotropin releasing hormone-agonist (GnRH-a) and recombinant human chorionic gonadotropin (r-hCG) plus rescue oocyte retrieval might reveal oocytes in patients with recurrent empty follicle syndrome. CASE: Endogenous luteinizing hormone was triggered with a GnRH-a (Buserelin [Suprefact pro-injection, Aventis-Pharma, Turkey], 250 microg subcutaneously) in a GnRH antagonist (Cetrorelix [Cetrotide 0.25, SeronoTurkey], 0.25 mg/d, starting on day 6), down-regulated cycle. At the first scheduled retrieval, 3 cumulus-oocytecorona complexes were recovered from the left ovary. During chemical denudation with hyaluronidase, 2 of them underwent lysis. The third was a zona-free, germinalvesicle-stage oocyte after mechanical denudation. Oocyte pickup was stopped, and recombinant human chorionic gonadotropin (hCG) (250 microg subcutaneously) was injected. Five cumulus-oocyte-corona complexes were retrieved from the right ovary 24 hours after rescue with recombinant hCG. Only mechanical denudation was done, and 4 zona-free oocytes with germinal vesicle breakdown were seen. All oocytes underwent intracytoplasmic sperm injection, and none of them were fertilized. CONCLUSION: Oocyte maturation defects should be included in etiologic mechanisms for counseling patients with empty follicle syndrome. 相似文献
