JEDI (jugular entrapment, dilated ventricles, intracranial hypertension) syndrome: a new clinical entity? A case report.

Patients with idiopathic intracranial hypertension are frequently obese women with normal/slit ventricles. Patients with high-pressure hydrocephalus, instead, present enlarged ventricles. We describe a 63-year-old woman with signs and symptoms of intracranial hypertension. Brain MRI revealed hydrocephalus. Venous Doppler ultrasound showed external compression of the omohyoid muscles on the internal jugular veins. During jugular vein decompression, intracranial pressure dropped from 18 to 6 mmHg. Patient is asymptomatic at 2-year follow-up, with decreased brain ventricles. These findings could represent a novel form of high-pressure hydrocephalus that can be successfully treated without a CSF shunt. We called this syndrome JEDI (jugular entrapment dilated ventricles intracranial hypertension).

Grisel's Syndrome: Non-traumatic Atlantoaxial Rotatory Subluxation-Report of Five Cases and Review of the Literature.

BACKGROUND: In children, when unresponsive neck rigidity and distress are observed after ear, nose and throat (ENT) surgical treatment or nasopharyngeal inflammation, Grisel's syndrome should be suspected. This is a rare syndrome involving non-traumatic rotatory subluxation of the atlantoaxial joint. Conservative management with external cervical orthoses and empirical antibiotic, muscle relaxant and analgesic therapy should be the first choice of treatment. Surgical stabilization is indicated when high-grade instability or failure of stable reduction are observed. The instability is graded according to the classification system devised by Fielding and Hawkins. Several recommendations for treatment are available in the literature, but there are no common guidelines. In this paper, the authors discuss the need for prompt diagnosis and treatment considerations. CASE DESCRIPTION: Five children with Fielding type I-III rotatory subluxation are reported. Three patients were treated with a cervical collar, and one patient was treated with skull traction and sternal-occipital-mandibular immobilizer (SOMI) brace application. Surgical treatment was necessary for one patient after failure of initial conservative management. The intervals between the onset of torticollis and radiological diagnosis ranged from 12 to 90 days. A relationship between an increased grade of instability and delayed diagnosis was observed. CONCLUSION: In children with painful torticollis following ENT procedures or nasopharyngeal inflammation, Grisel's syndrome should always be suspected. Cervical magnetic resonance imaging (MRI) allows prompt and safe diagnosis, and a three-dimensional computed tomography (CT) scan provides better classification of the instability. Surgery, which is indicated in cases of high-grade instability or failure of conservative treatment, may be avoided with prompt diagnosis.

Functional Outcome After Odontoid Fractures in the Elderly.

While several papers on mortality and the fusion rate in elderly patients treated surgically or non-surgically for odontoid fractures exist, little information is available on quality of life after treatment. The aim of treatment in these patients should not be fracture healing alone but also quality of life improvement.A literature search using PubMed identified seven papers including information on functional evaluation of 402 patients.Patients treated with anterior screw fixation had a good functional outcome in 92.6% of cases. This percentage seemed to decrease in octogenarians. Less information was available for patients treated with posterior approaches; it would seem that up to a half of such patients experienced pain and limitations in activities of daily living after surgery. Patients treated with a halo device had a functional outcome that was worse (or at least no better) than that of patients treated with surgery, with absence of limitations in activities of daily living in 77.3% of patients. Patients treated with a collar had a good functional outcome in the majority of cases, with absence of limitations in activities of daily living in 89% of patients.More studies are needed for evaluation of functional outcome, especially in patients treated with a collar, a halo device or a posterior approach.

Transpars Microscopic Approach for the Treatment of Purely Foraminal Herniated Lumbar Disc: A Clinical, Radiological, Two-center Study.

STUDY DESIGN: This is a prospective two-center study. OBJECTIVE: The aim of this study was to assess the safety and efficacy of treating patients with lumbar foraminal disc herniations via a microscopic transpars approach, with a clinical and radiological follow-up evaluation. SUMMARY OF BACKGROUND DATA: Purely foraminal lumbar disc herniations comprise about 5% of all lumbar herniated intervertebral discs. Operative management can be technically difficult, and the optimum surgical treatment remains controversial. METHODS: From January 2012 to January 2015, 47 patients were prospectively recruited. Patients were followed-up as outpatients at 1 week after discharge, then at 1, 6, and 12 months.A clinical multiparametric evaluation of patients including numeric rating scale (NRS), drugs intake, Macnab criteria, and working days lost was used.Postoperative dynamic x-rays (flexion, extension) were performed in all cases 12 months after surgery. RESULTS: No surgery-related complications occurred.Among the 35 patients who were not retired at the time of the study, 29 patients returned to work and to normal daily activities within 60 days after surgery.Pain evaluation at discharge showed a significant improvement of NRS score, from 8.93 to 1.45 at 12 months. Root palsy significantly improved in all cases already at 1-month follow-up. Drugs intake analysis showed that at 6-month follow-up, no patients used steroids, or opioids, 17 patients used non-steroidal anti-inflammatory drugs when needed, and 29 patients (61.7%) used no drugs for pain relief. No significant variations occurred at 12-month-follow-up.At 12-month follow-up, excellent or good outcome (following Macnab criteria) was achieved in 36 (76.6%) and 8 (17%) patients, respectively.There were no cases of spinal instability at 12-month radiological evaluation.No recurrence occurred at follow-up. CONCLUSION: Transpars microscopic approach is effective and safe for the treatment of FLDH, but larger studies are needed. LEVEL OF EVIDENCE: 3.
