The palatal masticatory mucosa thickness increased from the canine to premolar region but decreased at the first molar region and increased again in the second molar region, with the thinnest area at the first molar region and the thickest at the second premolar region. The canine to premolar region seems to be the most appropriate donor site that contains a uniformly thick mucosa. CT can be considered an alternative method for the measurement of palatal soft tissue thickness.

Biomarkers to indicate past exposure to radiation have not been entirely satisfactory. Using cDNA microarray hybridization to find new potential biomarkers, we identified highly expressed genes in human peripheral blood lymphocytes (PBLs) after irradiation 1 Gy ex vivo. The present set of radiation markers in PBLs was identified 12 h after radiation. A total of 44 genes were identified. However, when RT-PCR was performed with mRNA from the PBLs of five individuals, only four genes, including TRAIL receptor 2, DRAL (now known as FHL2), cyclin G, and cyclin protein gene, showed greater than 50% agreement between gene induction as detected by microarray analysis and by RT-PCR. When more than 32 donors were tested for the above four genes, greater than 85% agreement was obtained between gene induction measured by microarray analysis and by RT-PCR. There was a linear dose-response relationship between 0.5 and 4 Gy 12 h after irradiation; however, there was less linearity at later times. These results suggested that the relative expression levels of genes such as TRAIL receptor 2, FHL2, cyclin G, and cyclin protein gene in PBLs may provide estimates of radiation exposures.

ObjectiveTo evaluate the safety of cesarean myomectomy in large myomas sized >5 cm.MethodsOne hundred sixty-five pregnant women with myomas who delivered via cesarean section were identified. Ninety-six women had cesarean section without myomectomy, and 65 women underwent cesarean myomectomy. We compared the maternal characteristics, neonatal weight, myoma types, and operative outcomes between two groups. We further analyzed cesarean myomectomy group according to myoma size. The large myoma was defined as myoma >5 cm in size. The maternal characteristics, neonatal weight, and myoma types were compared between two groups. We also compared the operative outcomes such as preoperative and postoperative hemoglobin, operative time, and hospitalized days between two groups.ResultsThere were no significant differences in the maternal characteristics, myoma types, neonatal weight and operative outcomes between cesarean section without myomectomy and cesarean myomectomy. The subgroup analysis according to myoma size (>5 cm or not) in cesarean myomectomy group revealed that there were no significant differences in the mean hemoglobin change (1.2 vs. 1.3 mg/dL, P=0.6), operative time (90.5 vs. 93.1 minutes, P=0.46), and the length of hospital stay (4.7 vs. 5.2 days, P=0.15) between two groups. The comparison of maternal characteristics, neonatal weight, and myoma types between two groups also showed no statistical significance.ConclusionCesarean myomectomy in patients with large myomas is a safe and effective procedure.

PURPOSE: To compare the clinical outcomes of mix-and-match implantation of a diffractive extended depth of focus intraocular lens (IOL) (TECNIS Symfony ZXR00; Johnson & Johnson Vision) and a diffractive bifocal IOL (TECNIS ZLB00 +3.25 diopters [D]; Johnson & Johnson Vision) and bilateral implantation of a diffractive trifocal IOL (AcrySof IQ PanOptix; Alcon Laboratories, Inc). METHODS: This prospective comparative study compares the clinical outcomes of patients with age-related cataract undergoing cataract surgery using the IOLs described. Patients were divided into the mix-and-match group and the trifocal group. Assessment included monocular and binocular uncorrected distance visual acuity (UDVA), intermediate visual acuity (UIVA at 60 cm), and near visual acuity (UNVA at 40 cm), uncorrected defocus curves, contrast sensitivity, and reading speed. Quality of vision was measured with the Visual Function Questionnaire (VFQ-25). RESULTS: A total of 50 patients (25 in each group) were enrolled. At 6 months postoperatively, outcomes of binocular UDVA, UIVA, and UNVA were similar in both groups. The binocular defocus curve only differed at vergences of −0.50 to −1.00 D (better for the mix-and-match group; P = .032 and .004, respectively) and at −4.00 D (better for the trifocal group; P = .001). Significantly higher reading speeds in the mix-and-match group were measured at 0.7 and 0.5 logMAR ( P = .038 and .034, respectively). There were no significant differences between groups for contrast sensitivity and the results of the questionnaire. CONCLUSIONS: The mix-and-match implantation seemed to be a good option for patients with high demands for distance and intermediate visual acuity, whereas the trifocal IOL appeared to be more suitable for patients with enhanced near vision demands.
