We present a Swiss family with several members suffering from occipital and nervus intermedius neuralgia alone or in combination. We suggest that peripheral sensory anastomoses or central convergence of afferent pathways could explain neuralgia affecting two cranial nerves. The pedigree has two main characteristics: (1) affected individuals in two generations and (2) in the first generation the father is affected, in the second generation all women are affected, and none of the men. This is suggestive of an X-linked dominant or an autosomal dominant mode of inheritance.”

trigeminal neuralgia after microvascular decompression (MVD) may be due to insufficient decompression, dislocation of the implant to pad the neurovascular contact, or the development of granuloma. Here, we report on our experience with Teflon granuloma including

its treatment and histopathological examination. In a series of 200 patients with trigeminal Buparlisib neuralgia MVD was performed with Teflon felt according to Jannetta’s technique. In three patients with recurrent facial pain Teflon granuloma was found to be the this website cause for recurrence. In each instance, the granuloma was removed for histopathological examination. Mean age at the first procedure was 62.3 years and at the second procedure 66.3 years. Recurrence of pain occurred between 1 and 8.5 years after the first procedure. MRI scans demonstrated local gadolineum enhancement in the cerebellopontine angle, and CT scans showed local calcification. Intraoperatively dense fibrous tissue was found at the site of the Teflon granuloma. Histopathological RG-7853 examination revealed foreign body granuloma with multinuclear giant cells, collagen-rich hyalinized scar tissue, focal hemosiderin depositions, and microcalcifications. The Teflon granuloma was completely removed, and a new Teflon felt was used for re-decompression. Patients were free of pain after the second

procedure at a mean of 40.3 months of follow-up. Teflon granuloma is a rare cause for recurrent facial pain after MVD. Small bleeding into the Teflon felt at surgery might trigger its development. A feasible treatment option is surgical re-exploration, nerve preserving removal of the granuloma, and repeat MVD.”
“The seeking of a second opinion is the long-established process whereby a physician or expert from the same or a similar specialty is invited to assess a clinical case in order to confirm or reject a diagnosis or treatment plan. Seeking a second opinion has become more common in recent years, and the trend is associated with significant changes in the patient-doctor relationship. Telemedicine is attractive because it is not only fast but also affordable and thus makes it possible to reach highly qualified centres and experts that would otherwise be inaccessible, being impossible, or too expensive, to reach by any surface transport.
