OBJECTIVE: To analyze the results of sphenopalatine ganglion stimulation in treatment of chronic headache. MATERIALS AND METHODS: Medical histories of patients who underwent sphenopalatine ganglion stimulation in 4 clinical centers have been analyzed. The analysis included the type of pain and its characteristics, methods of surgery, CT, MRI, radiography before and after surgery. The follow-up data of patients with implanted pulse generators was collected in an outpatient clinic or by telephone review. RESULTS: The study included 15 patients with chronic refractory headache, including 14 with cluster headache and one female patient with features of trigeminal autonomic cephalgia without a clear definition of the type of pain. Trial stimulation was performed in 10 patients to determine analgesic effect. Among them stimulation was favorable in 7 cases, and 6 of them underwent pulse generator implantation. In total, 11 (73%) patients underwent implantation with a follow-up from 1 to 60 months. Among them only 6 (54%) patients use stimulation, the remaining 5 (46%) cases had device-related complications (migration, infection of system). Cluster headache has a significant improvement in long-term follow-up. CONCLUSIONS: Sphenopalatine ganglion stimulation may have high potential in the treatment of chronic drug-resistant cluster headache. The complication rate demonstrates that operative technique should be improved.

Generation of induced pluripotent stem cell lines ICGi021-A and ICGi022-A from peripheral blood mononuclear cells of two healthy individuals from Siberian population.

ICGi021-A and ICGi022-A iPSC lines were obtained by reprogramming PBMCs of two healthy women of the Siberian population using episomal non-integrating vectors expressing Yamanaka factors. iPSC lines expressed pluripotency markers, had a normal karyotype and demonstrated the ability to differentiate into derivatives of the three germ layers. Clinical exome sequencing data of the original biosamples of the donors are available in the NCBI SRA database. The generated cell lines are useful as "healthy" control in biomedical studies.
