Our study improved the description of an unclassified, clinico-radiologic entity, which could be described by the proposed acronym: TransIent Perivascular Inflammation of the Carotid artery (TIPIC) syndrome.
This study aims to demonstrate predictive factors for post traumatic syringomyelia (PTS), and in particular to correlate the role of insu ciency of reduction of a spinal fracture with the occurrence of syringomyelia. One hundred and twenty-eight spinal cord injured patients (SCI) were studied during the years 1992 and 1993. Among them, 75 underwent a complete and reliable evaluation including: review of the initial vertebral lesion, and of the surgery report, and a radiological study of the lesion site with standard X-rays, a CT scan, and an MRI. The CT Scan included slices in sagittal reconstructions and in the axial plane at the site of injury with the calculation of a percentage of canal stenosis in the two planes of the space. An MRI was carried out with T1 and T2 weighted images, including sagittal entire cord images in addition to sagittal and axial slices centred on the site of injury. A syrinx was diagnosed in 28% of the patients. The occurrence of a syrinx is signi®cantly correlated with spinal canal stenosis in the sagittal plane (DD) with a P50.001 and in the axial plane (DS) (P50.05). This present study demonstrates the major role of the insu ciency of reduction of the vertebral lesion in the genesis of a syrinx. The quality of the initial treatment of the vertebral injury is the ®rst step in the prevention of a syrinx. The treatment of a syrinx, besides techniques of drainage, must also take into account the spinal realignment.
Summary: Background: The Transient Perivascular Inflammation of the Carotid artery (TIPIC) syndrome is presumably a very rare disease characterized by a local transient inflammation of the tissue around the carotid artery. Its pathophysiology remains unknown. We performed an updated study of TIPIC syndrome cases in the setting of a multinational collaborative study. Methods: This study was conducted as an observational multinational retrospective individual patient level cohort study. Information from all known cases diagnosed with TIPIC syndrome in the literature (2005–2020) was collected after a semi-structured literature search of PubMed and Web of Science. We also collected unpublished information of patients from French, Swiss, and Italian vascular medicine or radiology departments. Results: A total of 72 patients were included and served for data analysis: 42 (58.3%) were women; the mean age was 47.9 (SD=11.4) years. Symptoms were unilateral in 92% of patients and 81.4% required pain killers. At baseline, irrespective of the imaging method used, the median thickness of the carotid lesions was 5 (Q1–Q3: 4–7; range: 2–11) mm and the median length of the lesion was 20 (Q1–Q3: 10–30; range: 3–50) mm. We found a positive linear correlation between thickness and length. At follow-up, the thickness of the carotid lesions decreased to a median of 2 (Q1–Q3: 1–3; range: 0–6) mm; the length decreased to a median 10 (Q1–Q3: 5–15; range: 0–41) mm. A linear correlation between baseline and follow-up values was observed for both thickness and length measurements. Symptoms disappeared after a median of 14 (Q1–Q3: 10–15) days. Thirteen patients experienced a recurrence after a median follow-up of 6 (Q1–Q3: 2–12) months. Conclusions: The present analysis elucidates clinical and sonographic characteristics of TIPIC syndrome, indicating the benign nature of this condition. A future international registry will study the long-term course of the disease.
BackgroundThe treatment of depression remains a challenge since at least 40% of patients do not respond to initial antidepressant therapy and 20% present chronic symptoms (more than 2 years despite standard treatment administered correctly). Repetitive transcranial magnetic stimulation (rTMS) is an effective adjuvant therapy but still not ideal. Intermittent Theta Burst Stimulation (iTBS), which has only been used recently in clinical practice, could have a faster and more intense effect compared to conventional protocols, including 10-Hz high-frequency rTMS (HF-rTMS). However, no controlled study has so far highlighted the superiority of iTBS in resistant unipolar depression.Methods/designThis paper focuses on the design of a randomised, controlled, double-blind, single-centre study with two parallel arms, carried out in France, in an attempt to assess the efficacy of an iTBS protocol versus a standard HF- rTMS protocol. Sixty patients aged between 18 and 75 years of age will be enrolled. They must be diagnosed with major depressive disorder persisting despite treatment with two antidepressants at an effective dose over a period of 6 weeks during the current episode. The study will consist of two phases: a treatment phase comprising 20 sessions of rTMS to the left dorsolateral prefrontal cortex, localised via a neuronavigation system and a 6-month longitudinal follow-up. The primary endpoint will be the number of responders per group, defined by a decrease of at least 50% in the initial score on the Montgomery and Asberg Rating Scale (MADRS) at the end of rTMS sessions. The secondary endpoints will be: response rate 1 month after rTMS sessions; number of remissions defined by a MADRS score of <8 at the endpoint and 1 month after; the number of responses and remissions maintained over the next 6 months; quality of life; and the presence of predictive markers of the therapeutic response: clinical (dimensional scales), neuropsychological (evaluation of cognitive functions), motor (objective motor testing) and neurophysiological (cortical excitability measurements).DiscussionThe purpose of our study is to check the assumption of iTBS superiority in the management of unipolar depression and we will discuss its effect over time. In case of a significant increase in the number of therapeutic responses with a prolonged effect, the iTBS protocol could be considered a first-line protocol in resistant unipolar depression.Trial registrationClinicalTrials.gov, Identifier NCT02376491.
