Notizen: Summary Background The 14 day results of this study reported elsewhere demonstrated that the Perfix® plug-and-patch was as effective as the Lichtenstein patch but not as cost-effective. The present analysis looks at the results at one year to measure quality of life between the two groups. Patients and Methods 141 patients were randomly allocated in a doubleblind manner to receive either a Lichtenstein patch (patch) or a Perfix® plug- and-patch (plug-and-patch) for primary inguinal hernia. Quality of life at 6 months and one year was assessed by the short-form 36 (SF36). On a 3 point scale patients were asked at one year to rate groin, wound and testicular discomfort. Results Physical function by SF36 was similar in the 2 groups at 6 months, but at one year in the patch group (95.11 +/-20.07) was significantly better (p 〈 0.05) than physical function in the plug-and-patch group (82.5 ± 20.98). At one year the number of patients with wound discomfort limiting work or social activities was significantly greater in patients receiving the plug-and-patch (n = 12) compared with patients receiving the patch (n = 4), p 〈 0.031. At one year, 4 of 70 patients receiving the plug-and-patch had required reoperation to remove the preformed plug-and-patch device and replace it with a flat Lichtenstein patch, because of wound pain which was limiting activity. Conclusion A significant proportion of patients suffer chronic pain after placement of a Perfix® plug-and-patch for primary inguinal hernia repair. Removal of the Perfix® device is required in approximately i in 20 patients (5.6% in this series).

Notizen: Abstract The iguanid lizard Sceloporus grammicus has a high level of karyotypic variability, and has often been cited as an example of chromosomal speciation. We examined a total of 2036 secondary spermatocytes from 30 S. grammicus males, and found that 16 of the 30 individuals (including a single lizard collected from a hybrid zone between two chromosome races) produced completely balanced spermatocytes. Fourteen of the 30 lizards (including both chromosomal heterozygotes and homozygotes) had relatively low (0.6% to 7.1%) levels of aneuploidy. Heterozygotes had a 1.1% increase over homozygotes in the number of aneuploid spermatocytes observed. The frequency of aneuploidy in S. grammicus may not be high enough to cause chromosomal speciation by any of the mechanisms that have been proposed for this complex. Most individuals showed balanced segregation of the autosomal trivalents, but nearly half of the lizards had a significant excess of spermatocytes with the X1 and X2 rather than the Y sex chromosomes. Five lizards had spermatocytes which had fission mutations not found in the somatic cells. As many as 5.9% of the spermatocytes in one individual had chromosomal mutations. This chromosomal mutation rate has important implications for chromosomal evolution in S. grammicus.
