CCH attack frequency reduction after psilocybin correlates with hypothalamic functional connectivity.

Objective: To evaluate the feasibility and prophylactic effect of psilocybin as well as its effects on hypothalamic functional connectivity (FC) in patients with chronic cluster headache (CCH).

Background: CCH is an excruciating and difficult-to-treat disorder with incompletely understood pathophysiology, although hypothalamic dysfunction has been implicated. Psilocybin may have beneficial prophylactic effects, but clinical evidence is limited.

Benign tumours leading to total penile denudation treated with Manuka honey dressings: A case report and review of literature.

Introduction: Penile denudation is a devastating condition often reconstructed with a split-thickness skin graft(STSG). As this kind of reconstruction is challenging, we present an non-invasive treatment using Manuka honey dressings with a satisfying result. This was performed as a salvage procedure after failed STSG.

Changes in Na+, K(+)-adenosinetriphosphatase, citrate synthase and K+ in sheep skeletal muscle during immobilization and remobilization.

The K+ balance and muscle activity seem to interact in a complex way with regard to regulating the muscle density of Na(+)-K+ pumps. The effect of immobilization was examined in ten sheep that had low muscle K+ content. Three additional sheep served as untreated controls.

VACTERL or MURCS association in a girl with neurenteric cyst and identical thoracic malformations in the father: a case of gonosomal mosaicism?

We report on a female infant with lethal congenital malformations including extreme hydrocephalus due to aqueductal stenosis, vertebral segmentation anomalies, fused costae, anal atresia, renal dysplasia, and bicornuate uterus with a double blind vagina. The VACTERL and the MURCS associations are possible diagnoses. Her father had a neurenteric cyst in infancy.

Biomechanical factors in the metaphyseal- and diaphyseal-lengthening osteotomy. An experimental and theoretic analysis in the ovine tibia.

A post hoc comparison of the mechanical factors that affected the outcome of experimental metaphyseal- and diaphyseal-lengthening osteotomies in sheep tibiae was performed. The resulting motions between bone segments at the metaphyseal and diaphyseal levels were estimated using measured fixator stiffnesses, postural muscle activity, ground reaction forces, and calculated internal and external loads. Relative displacements of bone segments of up to 2.
