Project description:Background:Trigeminal neuralgia (TN) is a chronic pain condition characterized by brief episodes of lancinating pain in one or more distributions of the trigeminal nerve. Episodes of pain secondary to TN are triggered by certain stimuli, such as chewing, shaving, or touching the face. Although a common cause of TN is compression of the trigeminal nerve root entry zone by an artery or vein, many cases of TN are idiopathic. However, there have been limited reports in the literature of familial TN. Case Presentation:A 31-year-old male presented with classic TN symptoms in the right V1/V2 distribution that recently progressed to the V3 distribution a case of familial TN. His father an brother both have TN. Carbamazepine, oxcarbazepine, and rhizotomy did not improve his symptoms. He was treated with stereotactic radiosurgery (SRS) with a dose of 85 Gy delivered to the proximal trigeminal root with improvement in his pain. We also review and summarize the over 160 cases of familial TN found in the literature. Conclusions:This is the first reported case of familial TN treated with SRS. Patients with familial TN are more likely to have bilateral disease, to present with earlier onset, and to become refractory to medical therapy and may require more aggressive approaches. We propose that SRS is a good treatment approach for these patients.

Project description:BackgroundGlossopharyngeal neuralgia (GPN) is an uncommon craniofacial pain syndrome. It is characterized by a sudden onset lancinating pain usually localized in the sensory distribution of the IX cranial nerve associated with excessive vagal outflow, which leads to bradycardia, hypotension, syncope, or cardiac arrest. This study aims to review our surgical experience performing microvascular decompression (MVD) in patients with GPN.MethodsOver the last 20 years, 14 consecutive cases were diagnosed with GPN. MVD using a microasterional approach was performed in all patients. Demographic data, clinical presentation, surgical findings, clinical outcome, complications, and long-term follow-up were reviewed.ResultsThe median age of onset was 58.7 years. The mean time from onset of symptoms to treatment was 8.8 years. Glossopharyngeal and vagus nerve compression was from the posterior inferior cerebellar artery in eleven cases (78.5%), vertebral artery in two cases (14.2%), and choroid plexus in one case (7.1%). Postoperative mean follow-up was 26 months (3-180 months). Pain analysis demonstrated long-term pain improvement of 114 ± 27.1 months and pain remission in 13 patients (92.9%) (P = 0.0001) two complications were documented, one patient had a cerebrospinal fluid leak, and another had bacterial meningitis. There was no surgical mortality.ConclusionsGPN is a rare entity, and secondary causes should be discarded. MVD through a retractorless microasterional approach is a safe and effective technique. Our series demonstrated an excellent clinical outcome with pain remission in 92.9%.

Project description:Bullous pemphigoid (BP) is a rare, life-threatening autoimmune blistering disease with pruritus and tension blisters/bullous as the main clinical manifestations. Glucocorticosteroids are the main therapeutic agents for it, but their efficacy is poor in some patients. Tofacitinib, a small molecule agent that inhibits JAK1/3, has shown incredible efficacy in a wide range of autoimmune diseases and maybe a new valuable treatment option for refractory BP. To report a case of refractory BP successfully treated with tofacitinib, then explore the underlying mechanism behind the treatment, and finally review similarities to other cases reported in the literature. Case report and literature review of published cases of successful BP treatment with JAK inhibitors. The case report describes a 73-year-old male with refractory BP that was successfully managed with the combination therapy of tofacitinib and low-dose glucocorticoids for 28 weeks. Immunohistochemistry and RNA sequencing were performed to analyze the underlying mechanism of tofacitinib therapy. A systematic literature search was conducted to identify other cases of treatment with JAK inhibitors. Throughout the 28-week treatment period, the patient experienced clinical, autoantibody and histologic resolution. Immunohistochemical analysis showed tofacitinib significantly decreased the pSTAT3 and pSTAT6 levels in the skin lesions of this patient. RNA sequencing and immunohistochemical testing of lesion samples from other BP patients identified activation of the JAK-STAT signaling pathway. Literature review revealed 17 previously reported cases of BP treated with four kinds of JAK inhibitors successfully, including tofacitinib (10), baricitinib (1), upadacitinib (3) and abrocitinib (3). Our findings support the potential of tofacitinib as a safe and effective treatment option for BP. Larger studies are underway to better understand this efficacy and safety.

Project description:BackgroundTrigeminal neuralgia is a severe facial pain disorder. Microvascular decompression is first choice surgical treatment of patients with classical TN. There exist few prospective studies with an independent evaluation of efficacy and complications after MVD.ObjectivesWe aimed to assess outcome and complications after microvascular decompression from our center.MethodsWe prospectively recorded clinical characteristics, outcome, and complications from consecutive patients with either classical or idiopathic (only patients with a neurovascular contact) trigeminal neuralgia undergoing microvascular decompression. Neurovascular contact was evaluated by 3.0 Tesla MRI. Patients were assessed before and 3, 6, 12, and 24 months after surgery by independent assessors.ResultsOf 115 included patients, 86% had a clinically significant outcome (i.e., BNI I - BNI IIIb). There was a significant association between an excellent surgical outcome and the male sex (OR 4.9 (CI 1.9-12.8), p = 0.001) and neurovascular contact with morphological changes (OR 2.5 (CI 1.1-6.0), p = 0.036). Significantly more women (12/62 = 19%) than men (2/53 = 4%) had a failed outcome, p = 0.019. The most frequent major complications were permanent hearing impairment (10%), permanent severe hypoesthesia (7%), permanent ataxia (7%), and stroke (6%). Most patients (94%) recommend surgery to others.ConclusionMicrovascular decompression is an effective treatment for classical and idiopathic (only patients with a neurovascular contact) trigeminal neuralgia with a high chance of a long-lasting effect. The chance of an excellent outcome was highest in men and in patients with classical trigeminal neuralgia. Complications are relatively frequent warranting thorough patient evaluation and information preoperatively.Trial registrationClinical.Trialsgov registration no. NCT04445766 .

Project description:We conducted a study to evaluate the follow-up characteristics of patients with trigeminal neuralgia (TN) and to evaluate the factors affecting long-term outcome of microvascular decompression (MVD) in TN. Between 1983 and 2003, 156 patients with TN treated with MVD by 4 neurosurgeons at University Medical Centre Groningen/the Netherlands were evaluated. Baseline data from operative outcome were evaluated using univariate and multivariate analysis. The group consisted of 156 patients with TN: 90 females and 66 males with a median follow-up period of 9.7 years. The average age of initial symptoms was 51 years. The average duration of symptoms was 58 months. Postoperative 22 patients had a facial hyperpathia or hyperesthesia. Postoperatively, 137 patients had immediate relief. Postoperatively 1 year, 140 patients still had a good outcome of the operation. Twenty-seven patients with good immediate postoperative results had recurrent pain. From the group of patients with typical TN, 82% had good long-term results after operation. Patients with typical TN and immediate postoperative remission, in univariate analysis, had significantly more often an excellent/good postoperative outcome. Immediate postoperative remission is an independent predictive factor for a good long-term outcome. The long-term results of MVD in majority of patients were good with no mortalities and no major morbidities. Patients with typical TN had better long-term outcomes and less recurrence.

Project description:ObjectiveTo compare complete neuroendoscopic and microscopic microvascular decompression (MVD) in primary trigeminal neuralgia (PTN) and their impacts on the microstructure of the trigeminal nerve.MethodsEighty-seven PTN patients admitted in our hospital from July 2017 to December 2019 were selected for this prospective study and divided into the endoscopic group (n=45) (complete neuroendoscopic MVD) and the microscope group (n=42) (microscopic MVD) according to the treatment method each patient underwent. All the patients underwent MRI scanning, and the fractional anisotropy (FA) scores and the apparent diffusion coefficient (ADC) values of the neurovascular compression (NVC) sites were measured. The operation times, the treatment efficacy, the microstructural changes in the trigeminal nerve, the complications, and the recurrence and mortality rates at one year after the operations were compared.ResultsThe endoscopic group observed a superior therapeutic effect compared with the microscope group one year after the surgeries (P=0.046). After the surgeries, the endoscopic group observed a greater increase in their FA values and a larger decline in their ADC values than the microscope group did (P=0.014, 0.015, 0.011, 0.002). The complication rate in the endoscopic group was 11.11%, and the complication rate in the microscopic group was 30.95% (P=0.022). One year after the surgeries, we found a lower recurrence rate in the endoscopic group (P=0.001). The perforator vessels from the offending vessel to the outlet area of the durmedulla, the distances between the front edge of the bone window and the inner surfaces of the petrous part of the temporal bone ≥ the distance between the duration ≥ the duration of conventional MVD were independent risk factors for complications after MVD in the hemifacial spasm patients (P=0.001, 0.037, 0.023, 0.005).ConclusionComplete neuroendoscopic MV yields better long-term treatment outcomes than microscopic MVD, and it is more effective at improving the microstructure of the trigeminal nerve and has fewer postoperative complications.

Project description:BackgroundGlossopharyngeal neuralgia is a rare neurovascular compression syndrome that can lead to paroxysmal craniofacial pain and sometimes cardiovascular symptoms.[1,2] The characteristic pathology involves a vessel (commonly a branch/loop of PICA) compressing the nerve at the root entry/exit zone at the brainstem.[1] Microvascular decompression is a commonly used treatment approach for patients that have failed conservative measures.[2].Case descriptionA 72-year-old male presented to the ED following four episodes of syncope. The patient had a multi-year history of right-sided burning/stabbing pain involving the submandibular area and posterior throat. His syncope was related to symptomatic bradycardia that would occur during episodes of pain. His pain was exacerbated by speaking and swallowing and could be triggered by placing his finger in the right external auditory meatus. Interestingly, this maneuver would also trigger his bradycardia. The patient had failed previous pharmacotherapy, and a pacemaker had been placed to protect him from periods of hypotension. MRI/MRA of the brain and cervical spine were unremarkable. Due to his profoundly symptomatic status, the patient was offered a right retrosigmoid craniotomy for microvascular decompression of the right glossopharyngeal nerve. The patient had complete resolution of his pain and bradycardia immediately post-operatively. He was discharged on the second postoperative day and his pacemaker was ultimately removed. The patient continues to be pain free and off medication.ConclusionHere we present a video case report of microvascular decompression with favorable outcome for an interesting presentation of glossopharyngeal neuralgia. The patient gave informed consent for surgery and video recording.

Project description:BackgroundMicrovascular decompression (MVD) is already the preferred surgical treatment for medically refractory neurovascular compression syndromes (NVC) such as hemifacial spasm (HFS), trigeminal neuralgia (TN), and glossopharyngeal neuralgia (GPN). Endoscopy has significantly advanced surgery and provides enhanced visualization of MVD. The aim of this study is to analyze the efficacy and safety of fully endoscopic microvascular decompression (E-MVD) for the treatment of HFS, TN, and GPN, as well as to present our initial experience.Materials and methodsThis retrospective case series investigated fully E-MVD performed in 248 patients (123 patients with HFS, 115 patients with TN, and 10 patients with GPN ) from December 2008 to October 2021 at a single institution. The operation duration, clinical outcomes, responsible vessels, intra- and postoperative complications, and recurrences were recorded. Preoperative and immediate postoperative magnetic resonance imaging (MRI) and computerized tomography (CT) were performed for imageological evaluation. The Shorr grading and Barrow Neurological Institute (BNI) pain score were used to evaluate clinical outcomes. The efficacy, safety, and risk factors related to the recurrence of the operation were retrospectively analysed, and the surgical techniques of fully E-MVD were summarised.ResultsA total of 248 patients (103 males) met the inclusion criteria and underwent fully E-MVD were retrospectively studied. The effective rate of 123 patients with HFS was 99.1%, of which 113 cases were completely relieved and 9 cases were significantly relieved. The effective rate of 115 patients with TN was 98.9%, of which 105 cases had completely pain relieved after surgery, 5 cases had significant pain relieved, 4 cases had partial pain relieved but still needed to be controlled by medication. The effective rate of 10 patients with GPN was 100%, 10 cases of GPN were completely relieved after surgery. As for complications, temporary facial numbness occurred in 4 cases, temporary hearing loss in 5 cases, dizziness with frequent nausea and vomiting in 8 cases, headache in 12 cases, and no cerebral hemorrhage, intracranial infection, and other complications occurred. Follow-up ranged from 3 to 42 months, with a mean of 18.6 ± 3.3 months. There were 4 cases of recurrence of HFS and 11 cases of recurrence of TN. The other effective patients had no recurrence or worsening of postoperative symptoms. The cerebellopontine angle (CPA) area ratio (healthy/affected side), the length of disease duration, and the type of responsible vessels are the risk factors related to the recurrence of HFS, TN, and GPN treated by fully E-MVD.ConclusionsIn this retrospective study, our results suggest that the fully E-MVD for the treatment of NVC such as HFS, TN, and GPN, is a safe and effective surgical method. Fully E-MVD for the treatment of NVC has advantages and techniques not available with microscopic MVD, which may reduce the incidence of surgical complications while improving the curative effect and reducing the recurrence rate.

Project description:Cardiac tamponade is a medical emergency requiring prompt recognition and intervention to avoid potentially fatal consequences. We present a case series of ventricular dysfunction and cardiogenic shock following pericardiocentesis in 3 patients with pericardial effusions at The Ottawa Hospital between 2014 and 2020. This report highlights the need for monitoring post-pericardiocentesis and raises awareness of this phenomenon, particularly in patients with malignancy. We propose a novel pressure-monitoring protocol to guide drainage and prevent development of pericardial decompression syndrome. The novel teaching points include limiting drainage to prevent development of pericardial decompression syndrome and a protocol for intra-pericardial pressure monitoring.
