Accumulation of Gadolinium in Human Cerebrospinal Fluid : Article Reports

In this study  gadolinium was quantified by using inductively coupled plasma mass spectrometry of CSF samples from patients who underwent gadobutrol-enhanced magnetic resonance (MR) imaging followed by lumbar puncture within 30 days (gadobutrol group) or patients who underwent lumbar puncture without history of gadolinium-enhanced MR imaging (control group). CSF total protein level of 35 mg/dL or lower was used as a surrogate marker of an intact blood-brain barrier (BBB).Reference :  https://doi.org/10.1148/radiol.2018171105Famous Radiology Blog http://www.sumerdoc.blogspot.com TeleRad Providers at www.teleradproviders.com Mail us at sales@teleradproviders.com

ABSTRACT Objective: To describe a case of a male adolescent with symptomatic idiopathic intracranial hypertension (IIH) associated with obesity treated with bariatric surgery. Case description: A 16-year-and-6-month-old severely obese boy [weight: 133.6 kg; height: 1.74 m (Z score: +0.14); BMI: 44.1 kg/m2 (Z score: +4.4)], Tanner pubertal stage 5, presented biparietal, high-intensity, and pulsatile headaches, about five times per week, associated with nocturnal awakenings, and partial improvement with common analgesics, for three months. Ophthalmologic evaluation evidenced bilateral papilledema. Cranial computed tomography...

We report a patient with relapsing-remitting multiple sclerosis, who developed rheumatoid arthritis after exposure to natalizumab. While some multiple sclerosis therapies are known to unmask autoimmune conditions, natalizumab is rarely implicated as a cause of alternative autoimmunity. This case illustrates an unusual clinical scenario which may support recent scientific work suggesting that when natalizumab blocks T helper 1 cells from entering the central nervous system, T helper 17 cells may continue to migrate into immune-privileged spaces and cause pathologic inflammation.Brief Background: Multiple sclerosis (MS) pati...

Abstract The American College of Emergency Physicians (ACEP) published guidelines in July 2019 on the diagnosis and management of acute nontraumatic headaches in the emergency department, focusing predominantly on the diagnosis of subarachnoid hemorrhage and the role of imaging and lumbar puncture in diagnosis. The ACEP Clinical Policies document is intended to aide Emergency Physicians in their approach to patients presenting with acute headache and to improve the accuracy of diagnosis, while promoting safe patient care practices. The Clinical Policies document also highlights the need for future research into be...

Conclusions: Spontaneous CSF leaks arising from the PCF are rare and may present more commonly with meningitis. Identification requires careful review of imaging.

Conclusion: Neuroimaging findings are useful tools with high diagnostic sensitivity in IIH. The most sensitive finding was increased peri-optic CSF. The utility of these neuroimaging correlates and their potential significance as solely diagnostic markers in IIH should be investigated in future large-scale studies.

SUMMARY: Patients with spinal muscular atrophy often have complete interlaminar osseous fusion, precluding lumbar puncture via the standard interlaminar approach. Recently, we have developed a new coaxial curved-needle variation of fluoroscopy-guided transforaminal lumbar puncture for intrathecal injections in this patient population. Between October 2017 and November 2018, fifty-nine consecutive transforaminal lumbar punctures using this technique were performed in 12 patients with spinal muscular atrophy for intrathecal nusinersen injection, with a 100% technical success rate and no C1–2 punctures required. One maj...

AbstractPurpose of ReviewPost dural puncture headache (PDPH) is a relatively common complication which may occur in the setting of inadvertent dural puncture (DP) during labor epidural analgesia and during intentional DP during spinal anesthetic placement or diagnostic lumbar puncture. Few publications have established the long-term safety of an epidural blood patch (EBP) for the treatment of a PDPH.Recent FindingsThe aim of this pilot study was to examine the association of chronic low back pain (LBP) in patients who experienced a PDPH following labor analgesia and were treated with an EBP. A total of 146 patients were co...

AbstractHeadache is a significant reason for access to Emergency Departments (ED) worldwide. Though primary forms represent the vast majority, the life-threatening potential of secondary forms, such as subarachnoid hemorrage or meningitis, makes it imperative for the ED physician to rule out secondary headaches as first step, based on clinical history, careful physical (especially neurological) examination and, if appropriate, hematochemical analyses, neuroimaging or lumbar puncture. Once secondary forms are excluded, distinction among primary forms should be performed, based on the international headache classification cr...
