Tendon normal

peer reviewedLe tendon a été associé au nerf pendant plus de 15 siècles. Ce dogme n'a été rompu qu'en 1745 par les travaux d'Albrecht Von Haller. Embryologiquement, il provient du mésoderme paraxial, du mésoderme de la lame latérale et de l'ectoderme. Il permet la transmission des forces générées par le muscle et est principalement composé de faisceaux de collagène de type I, de glycoprotéines, de protéoglycans, d'eau, de ténocytes et de ténoblastes. L'enthèse, jonction entre l'os et le tendon, peut être fibreuse ou fibrocartilagineuse. La jonction myotendineuse, quant à elle, représente une unité avec des liaisons entre les myocytes et les faisceaux de collagène. Sa vascularisation varie en fonction de la localisation du tendon et s'altère avec l'âge, l'intensité de l'effort, la compression, la friction et la torsion. Il est innervé par des nerfs sensoriels dont les fibres afférentes proviennent des troncs cutanés, musculaires et péritendineux. Sa courbe de déformation permet de comprendre sa biomécanique. En effet, ce tissu est viscoélastique. La mécanotransduction est un processus physiologique par lequel les cellules tissulaires détectent et produisent une réponse biochimique à un stimulus mécanique. L'entraînement favorise la synthèse de collagène de type I et dans une moindre mesure sa dégradation. L'immobilisation, par contre, entraîne une diminution de son poids, de sa rigidité et de sa résistance à la traction. Dans le cas d'une lésion aiguë, la cicatrisation tendineuse s'étend sur un peu plus de 10 semaines et est composée de trois phases : inflammation, réparation et remodelage. Le vieillissement tendineux entraîne un risque plus important de lésions tendineuses. Une diminution de la quantité de collagène et de protéine est alors observée. L'échographie voire l'imagerie par résonance magnétique (IRM) sont les examens d'imagerie médicale de choix en cas de suspicion de tendinopathie

Sylvius aqueduct septum

We present a case of chronic hydrocephalus discovered in adulthood through an episode of acute decompensation. Multimodal imaging revealed the cause of this hydrocephalus to be a membranous septum of the aqueduct of Sylvius, a condition for which few reports exist

Familial Adhesive Arachnoiditis Associated with Syringomyelia

Adhesive arachnoiditis is a rare condition, often complicated by syringomyelia. This pathologic entity is usually associated with prior spinal surgery, spinal inflammation or infection, and hemorrhage. The usual symptoms of arachnoiditis are pain, paresthesia, and weakness of the low extremities due to the nerve entrapment. A few cases have had no obvious etiology. Previous studies have reported one family with multiple cases of adhesive arachnoiditis. We report a second family of Belgian origin with multiple cases of arachnoiditis and secondary syringomyelia in the affected individuals

When rhinosinusitis reveals a systemic disease

peer reviewedThis retrospective analysis is concerned with 10 patients suffering from granulomatosis with polyangitis (GPA, Wegener's disease), who were followed up in a tertiary care Ear, Nose, and Throat (ENT) department. The inaugural events took place in the ENT field (8 patients), the lung (2 patients), the vestibule (1 patient), or the oral cavity (1 patient). The ENT manifestations during the disease evolution involved the rhinologic (osetocartilaginous--6 cases; mucosal--9 cases), the otologic (3 cases), or the laryngeal area (2 cases). Facial pain was noted in 6 cases and residual hyposmia in 5. We observed 5 cases of lung involvement, 3 cases of renal involvement, and 4 cases of ocular involvement. An aseptic meningitis was seen in 1 case and the muscles were affected in 6 cases. The average delay between symptom onset and diagnosis was 26 months. Endoscopy, imaging techniques, and determination of antineutrophil antibodies (ANCA) were used to reach the diagnosis. Sinus biopsies were contributive in 6 cases. The patients were treated with immunosuppressive drugs and/or surgery. After treatment, remission was obtained in 6 patients

Bilateral tubal incarceration into the broad ligaments caused by pelvic endometriosis: A case report

Introduction: Endometriosis is characterised by the presence of functional endometrial tissue outside the uterus. Salpinges are a common location of endometriotic implants. Endometriosis located into the broad ligament is a rare event. Case description: A 38-year-old infertile woman presented to our attention with moderate left iliac fossa pain after menses and intermenstrual bleeding. Transvaginal ultrasounds and pelvic magnetic resonance evidenced the presence of bilateral haematosalpinges. At the laparoscopic pelvic exploration, fallopian tubes were absent. Opening and dissecting the apical portion of the broad ligaments, we identified bilateral haematosalpinges incarcerated in the homolateral broad ligaments. We performed bilateral salpingectomy. Histological examination confirmed the presence of endometriosis. Conclusion: Care must be taken to the diagnostic assessment, counselling about the surgical programme before the intervention especially in patients during the reproductive period when the possibility of ablative surgery and subsequent need for an assisted reproductive technique exists

Cervicothoracic neuroblastomas : benefits of transmanubrial osteomuscular-sparing approach

peer reviewedWe report the case of a child suffering from a neonatal cervicomediastinal neuroblastoma encasing the left subclavian artery and the left vertebral artery. There is only a few pediatric tumors extending from the neck to the upper part of the thorax. Because of the complex vascular and neurological anatomy of this area, the surgical excision of these cervicothoracic neuroblastomas is a real challenge. It is why, when we decided to propose a surgical management, we used the Transmanubrial Osteomuscular-Sparing Approach (TOSA), of which technique and benefits will be explained in this article
