RESUMO

OBJECTIVES: To study the factors influencing the short-term (28 days) efficacy of initial adrenocorticotropic hormone (ACTH) therapy for infantile epileptic spasms syndrome (IESS), as well as the factors influencing recurrence and prognosis. METHODS: The clinical data were collected from the children with IESS who received ACTH therapy for the first time in the Department of Pediatric Neurology, Xiangya Hospital of Central South University, from April 2008 to January 2018 and were followed up for ≥2 years. The multivariate logistic regression analysis was used to evaluate the factors influencing the short-term efficacy of ACTH therapy, recurrence, and long-term prognosis. RESULTS: ACTH therapy achieved a control rate of seizures of 55.5% (111/200) on day 28 of treatment. Of the 111 children, 75 (67.6%) had no recurrence of seizures within 12 months of follow-up. The possibility of seizure control on day 28 of ACTH therapy in the children without focal seizures was 2.463 times that in those with focal seizures (P<0.05). The possibility of seizure control on day 28 of ACTH therapy in the children without hypsarrhythmia on electroencephalography on day 14 of ACTH therapy was 2.415 times that in those with hypsarrhythmia (P<0.05). The possibility of recurrence within 12 months after treatment was increased by 11.8% for every 1-month increase in the course of the disease (P<0.05). The possibility of moderate or severe developmental retardation or death in the children without seizure control after 28 days of ACTH therapy was 8.314 times that in those with seizure control (P<0.05). The possibility of moderate or severe developmental retardation or death in the children with structural etiology was 14.448 times that in those with unknown etiology (P<0.05). CONCLUSIONS: Presence or absence of focal seizures and whether hypsarrhythmia disappears after 14 days of treatment can be used as predictors for the short-term efficacy of ACTH therapy, while the course of disease before treatment can be used as the predictor for recurrence after seizure control by ACTH therapy. The prognosis of IESS children is associated with etiology, and early control of seizures after ACTH therapy can improve long-term prognosis.

RESUMO

OBJECTIVE: Acute low back pain (LBP) is a common condition that can be chronic if not properly treated. Aceclofenac and eperisone hydrochloride are commonly prescribed drugs for acute LBP and muscle spasms. Therefore, NVP-1203, a fixed-dose combination of 100 mg aceclofenac and 75 mg eperisone hydrochloride, is being developed. This study aimed to evaluate the efficacy and safety of NVP-1203 compared to those of a single administration of 100 mg aceclofenac in patients with acute LBP and muscle spasms. PATIENTS AND METHODS: Overall, 455 patients with acute LBP and muscle spasms were enrolled. The patients were assigned to NVP-1203 or Airtal group (aceclofenac 100 mg). The primary efficacy endpoint was the mean change in the 100 mm pain movement and resting visual analog scale (VAS) scores on treatment day 7. RESULTS: The mean change in the 100 mm pain movement/resting VAS scores from baseline to day 7 was -49.7 ± 21.5/-41.0 ± 19.4 mm and -38.8 ± 18.9/-33.8 ± 18.0 mm for the NVP-1203 and Airtal groups, respectively. The differences between the two groups were statistically significant (movement, p < 0.0001; resting, p = 0.0002). Differences in least-square (LS) mean change of the 100 mm pain movement/resting VAS score between the two groups using the analysis of covariance (ANCOVA) model was -10.2/-7.4 mm, and the upper limit of the 95% confidence interval was -6.44/-4.16 mm. CONCLUSIONS: NVP-1203 is more effective in reducing pain than the 100 mg aceclofenac alone. However, the two drugs have similar safety profiles in patients with acute LBP and muscle spasms.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Berberis lycium Royle, a member of the Berberidaceae family, is a high-value medicinal plant with a documented history of usage in traditional medicine and has demonstrated significant therapeutic results among local populations throughout the globe. It is used traditionally in many parts of Pakistan to treat diarrhea, abdominal spasms, coughs, and chest problems. AIM OF THE STUDY: To investigate the antispasmodic, bronchodilator, and antidiarrheal effects of B. lycium and its possible underlying mechanisms through in silico, in vitro, and in vivo studies. MATERIALS AND METHODS: LC ESI-MS/MS analysis was used to identify bioactive components within the hydromethanolic extract of B. lycium. In silico studies, including network pharmacology and molecular docking, were utilized to investigate the antispasmodic and bronchodilator properties of the extract's bioactive components. In vitro pharmacological studies were conducted using isolated rabbit jejunum, trachea, urinary bladder, and rat ileum preparations. In vivo antidiarrheal activities were conducted in mice, including castor oil-induced diarrhea, intestinal transit, and castor oil-induced enteropooling. RESULTS: The LC ESI-MS/MS analysis of the hydromethanolic extract of B. lycium identified 38 bioactive compounds. Network pharmacology study demonstrated that the mechanism of BLR for the treatment of diarrhea might involve IL1B, TLR4, PIK3R1, TNF, PTPRC, IL2, PIK3CD, and ABCB1, whereas, for respiratory ailments, it may involve PIK3CG, TRPV1, STAT3, ICAM1, ACE, PTGER2, PTGS2, TNF, MMP9, NOS2, IL2, CCR5, HRH1, and VDR. Molecular docking research revealed that chlorogenic acid, epigallocatechin, isorhamnetin, quinic acid, gallic acid, camptothecin, formononetin-7-O-glucoside, velutin, caffeic acid, and (S)-luteanine exhibited a higher docking score than dicyclomine with validated proteins of smooth muscle contractions such as CACB2_HUMAN, ACM3_HUMAN, MYLK_HUMAN, and PLCG1_HUMAN. In vitro investigations demonstrated that Blr.Cr, Blr.EtOAc, and Blr.Aq relaxed spontaneously contracting jejunum preparations; carbachol (1 µM)-induced and K+ (80 mM)-induced jejunum, trachea, and urinary bladder contractions in a concentration-dependent manner, similar to dicyclomine. Moreover, Blr.Cr, Blr.EtOAc, and Blr.Aq exhibited a rightward shift in Ca+2 and carbachol cumulative response curves, similar to dicyclomine, demonstrating the coexistence of antimuscarinic and Ca+2 antagonistic mechanisms due to the presence of alkaloids and flavonoids. In vivo antidiarrheal activities showed that the hydromethanolic extract was significantly effective against castor oil-induced diarrhea and castor oil-induced enteropooling, similar to loperamide, and charcoal meal intestinal transit, similar to atropine, in mice at doses of 50, 100, and 200 mg/kg body weight, which supports its traditional use in diarrhea. CONCLUSION: The dual blocking mechanism of muscarinic receptors and Ca+2 channels behind the smooth muscle relaxing activity reveals the therapeutic relevance of B. lycium in diarrhea, abdominal spasms, coughs, and chest problems.

RESUMO

INTRODUCTION: The transradial approach for coronary artery catheterisation has increased in popularity compared to the transfemoral approach for patients undergoing percutaneous coronary interventions. However, radial artery spasm continues to be a major complication of the procedure. Current management strategies vary concerning radial artery spasm and there is limited evidence of practice in the Australian context. AIM: To identify the predictors of radial artery spasm and the medications used for its prevention and management. METHODS: A descriptive cross-sectional study was carried out over a three-month period in two tertiary hospitals in NSW, Australia. A self-administered pre-procedural survey was completed by patients undergoing coronary artery catheterisation. This survey collected socio-demographic data and assessed anxiety using the Spielberger State-Trait Anxiety Inventory. Procedural data, including length of procedure, equipment used, occurrence of radial artery spasm, and medications given, were collected post-procedure by the interventionalist. RESULTS: Of the 169 participants, over half were male (59.8%) and aged 66 years or older (56.8%). Radial artery spasm was reported in 24 (14.2%) participants. Rates of spasm were significantly higher among females (66.6%, p = 0.004), those aged under 65 years (62.5%, p = 0.001) and those who reported a medical history of anxiety (33.3%, p = 0.0004). There were no significant differences in State and Trait anxiety scores among those who had RAS and those who did not. Logistic regression identified younger age as the only statistically significant predictor of RAS (OR 0.536; 95% CI 0.171-1.684; p = 0.005). To prevent radial artery spasm most patients received midazolam (n = 158; 93.5%), nitrates (n = 133; 78.7%) and/or fentanyl (n = 124; 73.4%) prophylactically. Nitrates were the most frequently administered medication to treat radial artery spasm (78.7%). CONCLUSION: This study highlights that there is a need to develop a clearer understanding of the predictors of RAS, as identifying patients at risk can ensure prophylactic measures are implemented. This study identified nitrates as the preferred vasodilator as a preventative measure along with the use of sedation.

RESUMO

BACKGROUND AND IMPORTANCE: Hemi-laryngopharyngeal spasm (HeLPS) may result from vascular compression of the vagus nerve and can be treated using microvascular decompression. We describe the clinical characteristics and surgical treatment in a case of concurrent trigeminal neuralgia (TN) and HeLPS. CLINICAL PRESENTATION: A 44-year-old man presented with a 12-month history of right TN and 8-month history of intermittent episodes of repeated throat contractions associated with a very distressing choking sensation. Preoperative 3-dimensional fusion imaging demonstrated compression of the trigeminal nerve by the superior cerebellar artery and petrosal vein and compression of the vagus nerve by the posterior inferior cerebellar artery and one of its branches. Microvascular decompression was performed by a right standard retrosigmoid approach with enlarged craniotomy. Initially, the compression of the trigeminal nerve was identified by visual inspection. All the offending vessels were wrapped in Teflon felt, transposed away from the trigeminal nerve, and adhered to the tentorial membrane and petrous bone using fibrin glue. Furthermore, observation of the caudal rootlets of the vagus nerve revealed that the posterior inferior cerebellar artery and its branch compressed the ventral side of the nerve. These vessels were displaced antero-caudally with Teflon felt and fibrin glue; no other vessels were found around the trigeminal and vagus nerves. Postoperatively, the patient had immediate and complete resolution of symptoms of TN and HeLPS without recurrence at the 18-month follow-up. CONCLUSION: HeLPS may occur with TN, and neurosurgeons should identify the symptoms suspicious of this disease preoperatively.

RESUMO

Objective: To evaluate the efficacy and safety of nerve loop blocking in the treatment of blepharospasm caused by Meige syndrome. Methods: It was a retrospective case series study. Patients with Meige syndrome characterized by blepharospasm or blepharospasm-oromandibular dystonia who underwent nerve loop blocking in the Ophthalmology Department of Henan No. 3 Provincial People's Hospital from April 2018 to January 2020 were included. Before and after surgery, blepharospasm was graded, and the Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS) was used to score the symptoms of ocular and oral dystonia. The improvement rate of ocular spasm was calculated after surgery according to the scores. The postoperative complications were observed. The Wilcoxon rank test was used to compare the BFMDRS movement subscale scores before and after surgery. The independent sample Mann-Whitney U test was used to compare the improvement rates of eye spasm between male and female patients and between patients with and without combined oromandibular dystonia. Results: Among the 199 patients included, 64 (32.2%) were males, and 135 (67.8%) were females, aged 58 (51, 64) years (22-79 years). The postoperative follow-up period was 24 (21, 28) months. Preoperatively, blepharospasm was graded as grade 3 in 12 patients (6.0%) and grade 4 in 187 patients (94.0%), while the postoperative blepharospasm grades were grade 0 in 100 patients (50.3%), grade 1 in 64 patients (32.2%), grade 2 in 31 patients (15.6%), and grade 3 in 4 patients (2.0%). There was statistically significant difference in the BFMDRS scores of ocular dystonia before and after surgery [8.0 (8.0, 8.0) vs. 0.0 (0.0, 1.0); Z=-12.41, P<0.001]. The improvement rate of blepharospasm in all patients was 100% (87.5%, 100%), ranging from 43.8% to 100%, with no statistically significant difference between patients of different genders and between patients with and without combined oral dystonia (both P>0.05). Statistically significant difference existed in the scores of oral dystonia before and after surgery [2.0 (0.5, 4.5) vs. 1.0 (0.5, 2.0); Z=-4.38, P<0.001], with 25 of 65 patients (38.5%) having their oral symptoms improved. Postoperative complications included eyelid valgus (7.5%, 15/199), frontal numbness (100%, 199/199) and tearing (89.9%, 179/199). Conclusion: Nerve loop blocking is a relatively safe and effective method in the treatment of blepharospasm symptoms of Meige syndrome.

RESUMO

Verapamil and nitroglycerin are widely used to prevent radial artery spasm (RAS) during percutaneous cardiovascular procedures. However, these agents are not typically available in most African countries and consequently, isosorbide dinitrate is often the only spasmolytic treatment. Our aim was to compare the efficacy of isosorbide dinitrate alone versus isosorbide dinitrate used together with nicardipine to prevent RAS during transradial coronary procedures. This was a randomized controlled double-blind multicenter trial. Patients (n = 1,523) were randomized to receive either a sole therapy of isosorbide dinitrate (n = 760) or the combination of isosorbide dinitrate and nicardipine (n = 763). Our primary end point was the occurrence of RAS; defined as considerable perceived hindrance of catheter advancement. Our secondary end points were severe RAS; defined as (1) severe arm pain, (2) the need for either morphine or midazolam treatment, and (3) necessity for crossover to the contralateral radial or femoral artery. RAS incidence was reduced with the combination therapy versus isosorbide dinitrate alone (15% vs 25%, p <0.001), with a number needed to treat of 10 patients. There was also a significant reduction in the incidence of the secondary end points with combination therapy (3.6% vs 8.2%, p <0.001), with a number needed to treat of 22 patients. This result was driven by reductions in both femoral crossover (0.5% vs 2.4%, p = 0.003) and the use of morphine or midazolam injections (1.6% vs 3.5%, p = 0.02) with combination therapy. In conclusion, we demonstrated the superiority of the combination therapy of isosorbide dinitrate and nicardipine over isosorbide dinitrate alone in reducing the incidence of RAS.

RESUMO

BACKGROUND: To provide evidence, this review evaluated the methodological quality, risk of bias, and reporting quality of SRs/MAs in the treatment of Facial Spasm with acupuncture. METHODS: Systematic reviews and Meta analyses (SRs/MAs) of acupuncture for Facial Spasm were retrieved from 8 databases from inception to October 1, 2022. Two reviewers independently screened the literature and extracted the data, then used Assessment of Multiple Systematic Reviews-2 (AMSTAR-2), Bias Risk in Systematic Review (ROBIS), and Preferred Report Item for Systematic review and Meta-analysis (PRISMA), Grading of Recommendations, Assessment, Development and Evaluation (GRADE) to assess methodological quality, risk of bias, quality of reporting, and quality of evidence. RESULTS: A total of 8 SRs/meta-analyses were included. All the SRs were published between 2012-2022. Based on AMSTAR-2, 8 SRs were rated critically low quality. By using the ROBIS tool, 6 SRs were rated low-risk bias. With the PRISMA-A checklist, we found 2 out of 8 SRs were found adequately reported over 70%. With the GRADE system, no high-quality evidence was found, and only two outcomes provided moderate-quality evidence. Among the downgraded factors, the risk of bias within the original trials was ranked first, followed by publication bias, inconsistency, and imprecision. CONCLUSION: Acupuncture is a promising complementary treatment for HFS. However, due to the low quality of the SRs/MAs supporting these results, high-quality studies with rigorous study designs and larger samples are needed before widespread recommendations can be made.

RESUMO

The study was performed to assess and rationalize the traditional utilization of the fruit part of Grewia tenax (G. tenax). The phytoconstituents present in the methanolic extract were analyzed using Gas-Chromatography-Mass Spectroscopy (GC-MS), while the anti-diarrheal activity was investigated in the Swiss albino mice against castor oil-provoked diarrhea in vivo. The antispasmodic effect and the possible pharmacodynamics of the observed antispasmodic effect were determined in an isolated rat ileum using the organ bath setup as an ex vivo model. GC-MS findings indicate that G. tenax is rich in alcohol (6,6-dideutero-nonen-1-ol-3) as the main constituent (20.98%), while 3-Deoxy-d-mannoic lactone (15.36%) was detected as the second major constituents whereas methyl furfural, pyranone, carboxylic acid, vitamin E, fatty acid ester, hydrocarbon, steroids, sesquiterpenes, phytosterols, and ketones were verified as added constituents in the methanolic extract. In mice, the orally administered G. tenax inhibited the diarrheal episodes significantly (p < 0.05) at 200 mg/kg (40% protection), and this protection was escalated to 80% with the next higher dose of 400 mg/kg. Loperamide (10 mg/kg), a positive control drug, imparted 100% protection, whereas no protection was shown by saline. In isolated rat ileum, G. tenax completely inhibited the carbamylcholine (CCh; 1 µM) and KCl (high K+; 80 mM)-evoked spasms in a concentrations-mediated manner (0.03 to 3 mg/mL) by expressing equal potencies (p > 0.05) against both types of evoked spasms, similar to papaverine, having dual inhibitory actions at phosphodiesterase enzyme (PDE) and Ca2+ channels (CCB). Similar to papaverine, the inhibitory effect of G. tenax on PDE was further confirmed indirectly when G. tenax (0.1 and 0.3 mg/mL) preincubated ileal tissues shifted the isoprenaline-relaxation curve towards the left. Whereas, pre-incubating the tissue with 0.3 and 1 mg/mL of G. tenax established the CCB-like effect by non-specific inhibition of CaCl2-mediated concentration-response curves towards the right with suppression of the maximum peaks, similar to verapamil, a standard CCB. Thus, the present investigation revealed the phytochemical constituents and explored the detailed pharmacodynamic basis for the curative use of G. tenax in diarrhea and hyperactive gut motility disorders.

RESUMO

BACKGROUND: Perampanel is an antiepileptic drug. Some studies have documented the efficacy of perampanel in epileptic spasms. We aimed to evaluate the efficacy and safety of adjunctive perampanel therapy (PT) in patients with epileptic spasms. METHODS: We retrospectively surveyed the efficacy and safety of adjunctive PT in 14 patients with epileptic spasms at the Saitama Children's Medical Center between June 2016 and September 2021. Seizure outcomes and safety were evaluated 12 months after commencing PT. Response to perampanel was defined as complete remission of epileptic spasms for more than 3 months. RESULTS: The median age at onset of epileptic spasms was 0.4 years (range, 0.1-1.3 years). The etiology was structural in 11 patients, genetic in two, and unknown in one. The median age at the commencement of PT was 3.2 years (1.5-10.3 years). The initial and maintenance doses of perampanel were administered at 0.04 (range, 0.02-0.05) mg/kg/day and 0.12 (range, 0.03-0.24) mg/kg/day, respectively. Five of the 14 patients (35.7%) showed remission of epileptic spasms for more than 3 months at 12 months after PT; these patients had a structural etiology. The median duration between commencement of perampanel and spasm remission was 2 months (range, 1-6 months). No serious adverse effects occurred. CONCLUSIONS: This is the first case series evaluating adjunctive PT for epileptic spasms. PT is worth investigating to treat epileptic spasms in patients with structural etiologies. As our study population primarily comprised children aged 2 years and older, PT may be useful for epileptic spasms beyond infancy.

RESUMO

BACKGROUND: Computed tomography (CT)-guided percutaneous stylomastoid foramen puncture radiofrequency ablation for the treatment of hemifacial spasm has a significant clinical effect; however, related risk factors for recurrence have not been studied. OBJECTIVE: To investigate the risk factors for the recurrence of hemifacial spasm after radiofrequency ablation and construct a model for predicting recurrence. STUDY DESIGN: This is a single-center retrospective observational study. SETTING: The study was conducted at the Pain Department of the Affiliated Hospital of Jiaxing College in Jiaxing, China. METHODS: A retrospective analysis was performed on 99 patients diagnosed with primary hemifacial spasm (HFS) admitted to the Affiliated Hospital of Jiaxing University between August 2018 and December 2021. All patients underwent CT-guided percutaneous stylomastoid foramen radiofrequency ablation. Kaplan-Meier survival analysis, log-rank test, and Cox proportional risk regression model were used to analyze the clinical factors that affect the recurrence of patients with HFS after radiofrequency ablation, and a recurrence prediction model was established. RESULTS: Follow-up was 3-12 months; recurrence rates were 20.2%, 36.4%, and 71.9% at 3, 6, and 12 months postoperatively, respectively. Univariate analysis showed that puncture approach, operation time, and facial paralysis level were factors influencing recurrence in patients with HFS after radiofrequency ablation (P < 0.05). The multivariate Cox proportional risk regression model showed that the operative time and facial paralysis grade were independent factors for recurrence after radiofrequency ablation in patients with facial spasms. The recurrence risk function model of patients with facial spasms after radiofrequency ablation was expressed as h(t) = h0exp(-0.619X1-2.589X2), where X1 and X2 represent the operation time and facial paralysis grade, respectively. The likelihood ratio of the model was statistically significant (chi squared = 55.769, P < 0.001). LIMITATIONS: We look forward to increasing the sample size in follow-up studies and exploring relevant conclusions in randomized controlled trials. CONCLUSION: Long operation times and high-grade facial paralysis can reduce the risk of recurrence in patients with facial spasms. The constructed recurrence prediction model could serve as a reference for clinical diagnosis and treatment.

RESUMO

BACKGROUND: Distal trans-radial access (dTRA) is a novel technique of arterial cannulation in coronary interventions. The comparative efficacy of dTRA and conventional trans-radial access (TRA) in attenuating peri-procedural complications is unknown. METHODS: Embase and PubMed/MEDLINE were searched from their inception until June 25, 2022, for randomized clinical trials. Outcomes included were radial artery occlusion (RAO), radial artery spasm, hemostasis time, access time, unsuccessful cannulation, crossover rate, and early discharge after trans-radial stenting of coronary arteries (EASY) type I-III hematomas. Statistical analysis was conducted using the random effects model to derive risk ratios (RRs) and mean differences (MDs) with their corresponding 95% confidence intervals (CIs). RESULTS: A total of 6 randomized clinical trials comprising 3240 patients were included. Subjects were predominantly male (73%) and had a mean age of 66 years. The dTRA group had a lower risk of RAO [RR 0.43 (95% CI, 0.26-0.69); P = 0.0005; I 2 = 0%] and had a shorter hemostasis time [MD -22.85 min (95% CI, -39.06 to -6.65); P = 0.006; I 2 = 99%]. The dTRA group had a higher crossover rate [RR 3.04 (95% CI, 1.88-4.91); P = 0.00001; I 2 = 56%] and a longer access time [MD 0.68 min (95% CI, 0.17-1.18); P = 0.009; I 2 = 99%]. The TRA group had a lower rate of unsuccessful cannulation [RR 0.81 (95% CI, 0.70-0.95); P = 0.01; I 2 = 92%]. There was no significant difference between the groups for radial artery spasm and EASY type I-III hematomas. CONCLUSION: dTRA is a safe alternative to conventional TRA for coronary interventions with a lower risk of RAO. Future trials are required to further compare both approaches.

RESUMO

BACKGROUND Serotonin toxicity, often referred to as 'serotonin syndrome,' is a drug-induced condition due to excess serotonin released from brain synapses, resulting in symptoms that may be autonomic, neuromuscular, and/or cognitive in nature. Most cases involve more than 1 of the following drug regimens: monoamine oxidase inhibitors (MAOIs), serotonin releasers, selective serotonin reuptake inhibitors (SSRIs), or serotonin-norepinephrine reuptake inhibitors (SNRIs). This report is of a 70-year-old woman who presented with confusion and muscle spasms due to serotonin toxicity associated with paroxetine and quetiapine treatment. CASE REPORT An elderly woman with dementia presented to the Emergency Department with fever, altered mental status, labile blood pressures, and inducible clonus. No known medication dosage increases had been made, nor had any new serotonergic agents been added to the patient's drug regimen. She underwent a thorough workup in the Emergency Department and later during her hospitalization. A presumptive diagnosis of serotonin toxicity was made early on during her stay, with the etiology attributed to use of paroxetine and quetiapine. Clinical improvement was observed after benzodiazepine administration, discontinuation of offending agents, and a brief cyproheptadine course. The patient survived her hospital stay and was ultimately discharged to hospice care with a return to her baseline level of functioning. CONCLUSIONS Diagnosing serotonin toxicity requires a high degree of clinical suspicion and can occur in the absence of increased dosage of existing, or initiation of new, serotonergic agents.

RESUMO

The aim of this study was to investigate the frequency of hemorrhagic side effects of botulinum neurotoxin A injections (BoNT/A) for the treatment of benign essential blepharospasm (BEB) and hemifacial spasm (HFS) in patients taking antithrombotic drugs (ATD). A total of 140 patients were included (female: 65%; BEB: 75%; mean age: 70 ± 12 years). According to their current antithrombotic medication, participants were either assigned to the ATD group (41%), or to the control group (59%). The ATD group was further divided into subgroups depending on the medication administered: acetylsalicylic acid, ADP receptor antagonists, direct oral anticoagulants, vitamin-K antagonists, or dual antiplatelet therapy. The frequency of hemorrhagic side effects was recorded by retrospective analysis of past treatments as documented in the patient's file set in relation to the number of past treatments (hematoma frequency of past treatments, HFretro) as well as by a prospective survey capturing the side effects of one single treatment (hematoma frequency of actual treatment, HFactual). There was no significant difference in hematoma frequency between the ATD group and the control group, neither for past (HFretro: ATD: 2%; 45/2554; control: 4%; 109/2744) nor for the current BoNT/A treatments (HFactual: ATD: 30%; 16/53; control: 31%; 22/72). Even between ATD subgroups, hematoma frequency did not differ significantly. Overall, hemorrhagic side effects of the BoNT/A treatment for BEB and HFS were mild and non-disabling.

RESUMO

OBJECTIVE: This study aimed to determine the correlation between outcomes following adrenocorticotrophic hormone (ACTH) therapy and measurements of relative power spectrum (rPS), weighted phase lag index (wPLI), and graph theoretical analysis on pretreatment electroencephalography (EEG) in infants with non-lesional infantile epileptic spasms syndrome (IESS). METHODS: Twenty-eight patients with non-lesional IESS were enrolled. Outcomes were classified based on seizure recurrence following ACTH therapy: seizure-free (F, n = 21) and seizure-recurrence (R, n = 7) groups. The rPS, wPLI, clustering coefficient, and betweenness centrality were calculated on pretreatment EEG and were statistically analyzed to determine the correlation with outcomes following ACTH therapy. RESULTS: The rPS value was significantly higher in the delta frequency band in group R than in group F (p < 0.001). The wPLI values were significantly higher in the delta, theta, and alpha frequency bands in group R than in group F (p = 0.007, <0.001, and <0.001, respectively). The clustering coefficient in the delta frequency band was significantly lower in group R than in group F (p < 0.001). CONCLUSIONS: Our findings demonstrate the significant differences in power and functional connectivity between outcome groups. SIGNIFICANCE: This study may contribute to an early prediction of ACTH therapy outcomes and thus help in the development of appropriate treatment strategies.

RESUMO

This case example illustrates the challenging nature of managing axillary vein spasm. Once axillary vein spasm has been diagnosed, unnecessary attempts at venous puncture should be avoided as this can result in worsening of the spasm. Intravenous fluids should be infused from the ipsilateral venous access. Intravenous nitroglycerin from the ipsilateral access in incremental doses of 100-200 µg can help in relieving the spasm. It is imperative to wait for 5-10 minutes before re-attempting puncture. A repeat venogram should be performed to demonstrate resolution of spasm and guide the puncture. If spasm persists, puncture may be attempted in the medial part of the axillary vein or the subclavian vein. In refractory cases where the above measures fail, contralateral venous access may be required.

RESUMO

Objective: To analyze the genotypes and clinical phenotypes of patients with epilepsy associated with IQSEC2 gene variants. Methods: The genotypes, seizure types, electroencephalogram, neuroimage of 6 patients with IQSEC2 gene variants in the Department of Pediatrics, Peking University First Hospital from July 2019 to October 2021 were analyzed. Results: There were 5 males and 1 female. Six variants were de novo, including 2 frameshift variants (c.3801_3808dup/p.Q1270Rfs*130, c.1459_1460delAT/p.M487Vfs*2), 2 nonsense variants (c.3163C>T/p.R1055*, c.1417G>T/p.E473*), 1 in-frame deletion (c.2295_2297del/p.N765del) and 1 missense variant (c.2293A>G/p.N765D). Age at seizure onset ranged from 3 months to 2 years and 5 months. Multiple seizure types were observed, including epileptic spasms in 5 patients, focal seizures in 5 patients, tonic seizures in 3 patients, myoclonic seizures in 3 patients, atypical absence seizures in 2 patients and atonic seizures in 2 patients. All 6 patients showed global developmental delay before seizure onset. There were other clinical manifestations, including autistic features in 3 patients, microcephaly in 3 patients, dystonia in 2 patients and binocular esotropia in 1 patient. The electroencephalogram showed slow background activity and hypsarrhythmia in all 6 patients. Brain magnetic resonance imaging showed abnormal in 5 patients and normal in 1 patient. Five patients were diagnosed with infantile spasms. Among them, 4 patients had late-onset infantile spasms. One patient was unclassified developmental epileptic encephalopathy. The age of last follow-up ranged from 3 years and 2 months to 7 years and 2 months. All 6 patients still had seizures after multiple anti-seizure medications. Conclusions: The seizure onset of patients with IQSEC2 gene variants usually begins after 1 year of age. The common seizure types include epileptic spasms and focal seizures. Patients usually have a global developmental delay before seizure onset. IQSEC2 variants could be related to developmental and epileptic encephalopathy, and most patients are diagnosed with late onset infantile spasms. Epilepsy associated with IQSEC2 gene variants is usually refractory.

RESUMO

Oxygenated water (OW) contains more oxygen than normal drinking water. It may induce oxygen enrichment in the blood and reduce oxidative stress. Hypoxia and oxidative stress could be involved in epilepsy. We aimed to examine the effects of OW-treated vs. control on four rodent models of epilepsy: (1) prenatal betamethasone priming with postnatal N-methyl-D-aspartate (NMDA)-triggered spasm, (2) no prenatal betamethasone, (3) repetitive kainate injection, and (4) intraperitoneal pilocarpine. We evaluated, in (1) and (2), the latency to onset and the total number of spasms; (3) the number of kainate injections required to induce epileptic seizures; (4) spontaneous recurrent seizures (SRS) (numbers and duration). In model (1), the OW-treated group showed significantly increased latency to onset and a decreased total number of spasms; in (2), OW completely inhibited spasms; in (3), the OW-treated group showed a significantly decreased number of injections required to induce epileptic seizures; and in (4), in the OW-treated group, the duration of a single SRS was significantly reduced. In summary, OW may increase the seizure threshold. Although the underlying mechanism remains unclear, OW may provide an adjunctive alternative for patients with refractory epilepsy.
