Do naturally occurring variants in the HTR3B gene significantly alter properties of human heteromeric 5-hydroxytryptamine-3A/B receptors?
These results may help to explain earlier reported association findings of the frequent p.Y129S and p.V183I variants with psychiatric diseases. Replication studies with larger sample pools, especially regarding the rare p.S156R variant would be useful, to obtain an idea about the predisposing role of these single nucleotide polymorphisms as susceptibility variants.
Despite of numerous previously operated patients (38%), there was a high recurrence rate (42%) after excision of a pilonidal sinus and primary midline closure. Alternative operative techniques creating a lateral wound or the various skin flap procedures may be promising alternatives. We are in the process of changing our treatment strategy for patients suffering from a pilonidal sinus.
