Increased risk for post-operative corneal injuries in patients who undergo laparoscopic gynecologic surgery.

BACKGROUND: The objective of this study was to verify whether or not the incidence of post-operative corneal injuries (PCIs) in patients who undergo laparoscopic gynecologic surgery is higher than patients who undergo non-laparoscopic gynecologic surgery. METHODS: The peri-operative variables were extracted from the medical records of patients who underwent gynecologic surgery under general anesthesia at our institute between January 2004 and June 2010. The extracted variables were age, day of week of surgery, type of surgery (laparoscopy vs. non-laparoscopy), surgical scheduling (elective vs. emergent), pre-operative hemoglobin, surgery time, peri-operative transfusions, and PCIs. The association of peri-operative variables with PCIs was examined using univariate and multivariate analyses. RESULTS: A total of 6992 consecutive patients were included in this study. PCIs occurred in 23 patients (0.3%). Based on univariate analysis, the type of surgery and surgery times were associated with PCIs. Based on multivariate analysis, laparoscopy and lengthy surgery times significantly increased the risk for PCIs. The median duration of PCI symptoms was 3 days (range, 1-11 days); no patient had long-term sequalae. CONCLUSION: Laparoscopic gynecologic surgery increases the incidence of PCI compared with non-laparoscopic gynecologic surgery.

Association of cyclin D1 G870A polymorphism with uterine leiomyoma in women whose body mass index values are above 25 kg/m2.

BACKGROUND: Many studies have shown that a polymorphism (G870A) in cyclin D1 (CCND1) is associated with carcinogenesis in a variety of cancers. Our aim was to determine if an association exists between the CCND1 G870A polymorphism and uterine leiomyoma in Korean women. METHODS: Blood samples of 331 cases and 204 controls aged 47.4 +/- 7.6 and 46.8 +/- 10.4 years (mean +/- SD), respectively, were collected. CCND1 genotyping was determined by PCR and restriction fragment length polymorphism. RESULTS: Allelic frequencies of cases (A, 0.53; G, 0.47) were not significantly different from those of controls (A, 0.49; G, 0.51) (P = 0.22). After adjustment for menarche age and BMI, multivariate logistic regression analysis showed that the AA genotype was not associated with increased risk for uterine leiomyoma [odds ratio (OR) = 1.38, 95% confidence interval (CI); 0.85-2.26, P = 0.19]. However, in stratification analysis of cases and controls with BMI >25 kg/m(2), allelic frequencies of cases (A, 0.56; G, 0.44) were significantly different from controls (A, 0.36; G, 0.64) (P = 0.005), and the AA genotype was associated with increased risk for uterine leiomyoma (OR = 3.61, 95% CI; 1.02-12.73, P = 0.046). Furthermore, the OR for AA compared with combined GG and AG genotypes was 3.16 (95% CI 1.01-9.92, P = 0.048). CONCLUSIONS: The A allele and AA genotype of CCND1 G870A polymorphism have a significant association with an increased risk of the uterine leiomyoma in obese Korean women.
