The hind- and midfoot alignment computed after a medializing calcaneal osteotomy using a 3D weightbearing CT.

Purpose: A medializing calcaneal osteotomy (MCO) is a surgical procedure frequently performed to correct an adult acquired flatfoot (AAFD) deformity. However, most studies are limited to a 2D analysis of 3D deformity. Therefore, the aim is to perform a 3D assessment of the hind- and midfoot alignment using a weightbearing CT (WBCT) preoperatively as well as postoperatively.

Painless Swelling of the Left Jaw in a Two-Year-Old Boy.

We present a case of a 2-year-old boy with chronic suppurative osteomyelitis of the left jaw. A computed tomography (CT) scan demonstrated a periosteal reaction on the left side of the mandible with cortical destruction of the left mandibular head. The diagnosis could be confirmed histologically.

Exogenously administered substance P and neutral endopeptidase inhibitors stimulate fibroblast proliferation, angiogenesis and collagen organization during Achilles tendon healing.

Background: In the last few years much research has been conducted in methods to promote tendon healing. The aim of this study was to determine if the healing process after operative repair of rat Achilles tendons could be stimulated by the paratendinous injection of a sensory peptide, substance P (SP).

Methods: Ninety-six male Sprague-Dawley rats were randomly allocated to four groups: (I) control buffer injections, (II) injections of SP 10(-6) mol/kg body weight combined with a carrier, (III) injections of SP 10(-8) mol/kg BW with the carrier, and (IV) injections with the carrier only (thiorphan 1 micromol/kg BW and captopril 30 micromol/kg BW, both neutral endopeptidase inhibitors).

Influence of burst TENS stimulation on collagen formation after Achilles tendon suture in man. A histological evaluation with Movat's pentachrome stain.

Retrograde or antidromic stimulation of the nociceptive C fibres is known to lead to the release of sensory neuropeptides, such as substance P (SP), by the peripheral endings of sensory unmyelinated C nerve fibres. These neuropeptides play a role in the healing of soft tissues. Burst TENS (Transcutaneous Electric Nerve Stimulation) is known to be most effective in influencing retrograde C fibre-evoked activity.

Influence of burst TENS stimulation on the healing of Achilles tendon suture in man.

Retrograde or antidromic stimulation of the nociceptive C fibres is known to lead to the release of sensory neuropeptides Substance P (SP) and Calcitonin Gene-Related Peptide (CGRP) by the peripheral endings of these ultra-thin nerve fibres. These neuropeptides have, among others, a vasodilatory effect, which explains why they play a role in the healing of soft tissues. Burst TENS (Transcutaneous Electric Nerve Stimulation) is known to be most effective in influencing C fibre-evoked activity.
