“Since the introduction of the motile sperm organelle morphology examination, there has been increasing recognition of the fact that the presence of large nuclear vacuoles might have deleterious effects on embryo development. Nevertheless, one fundamental question still being debated is whether specific in-vitro conditions during the handling of semen have an impact on vacuole formation. This study’s objective was to analyse whether incubation Bafilomycin A1 temperature (20, 37

degrees C) or oxidative stress stimulates the formation of nuclear vacuoles. Furthermore, it examined whether vacuoles disappear in the presence of an acrosome reaction inducer. Therefore, a system of sperm-microcapture channels was developed

to permit the observation of the same living spermatozoa over a period of 24 h. Neither incubation at 37 degrees C nor induction of oxidative stress led to de-novo formation of nuclear vacuoles. Induction of the acrosome reaction using calcium ionophore A23587 did not lead to any modifications in the proportion of spermatozoa with vacuoles or to the disappearance of pre-existing vacuoles. According to these observations, it is concluded that nuclear vacuoles on the sperm head are already produced at earlier stages of sperm maturation and are not induced or modulated by routine laboratory environments.

“Purpose Different surgical techniques for pilonidal disease have been described in the

literature. In this study, our aim was to evaluate the influence of routine cavity drainage in the Karydakis flap technique.

Methods As much as 50 male patients with CAL-101 order pilonidal sinus who underwent the Karydakis flap operation were evaluated prospectively.The patients were assigned randomly into two groups (Group 1 with suction drain; Group 2 fibrin glue).

Results Fluid collection was encountered in 8 out of 50 patients (6.25%): 6 in Group 2 (24%) of which 4 experienced superficial, healed with simple dressing, the other 2 with substantial dehiscence healed with wound dressing; 2 in Group 1 (8%) were treated with wound punctures.There has been no recurrence in any of the patients during the follow-up period.The Karydakis flap operations can be performed with a near zero recurrence rate with the use of drains.

Conclusion We recommend the use of fibrin sealant with Karydakis flap procedure, but further studies are needed to confirm this conclusion.”
