The aim of this study was to estimate the efficacy of preemptive paracervical block or uterosacral ligament infiltration in reducing postoperative pain and opioid consumption after benign minimally invasive hysterectomy.Data Sources: We searched MEDLINE, Cochrane Library, Embase, ClinicalTrials.gov, and Google Scholar from inception until February 2020.Methods of Study Selection: We identified randomized placebo-controlled trials assessing the primary outcome of pain and opioid consumption after paracervical block or uterosacral infiltration in benign laparoscopic, vaginal, or robotic hysterectomy. Two investigators evaluated studies for risk of bias and quality of evidence.Tabulation, Integration, and Results: We reviewed 219 abstracts; 6 studies met the inclusion criteria: 3 using paracervical block (2 vaginal and 1 laparoscopic) and 3 using uterosacral ligament infiltration (all vaginal). Two studies were included in the meta-analysis (both vaginal hysterectomy). Because of lack of numerical data, or comparison, the other 4 studies are reported in narrative form.Three controlled trials reported a moderate benefit from paracervical block up to 8 hours after vaginal and 4 hours after laparoscopic surgery. Meta-analysis could not be performed because of the lack of numerical data for pooling results or the lack of a laparoscopic hysterectomy comparison group. Three trials reported that uterosacral infiltration decreases pain up to 6 hours after vaginal hysterectomy, and meta-analysis pooling the results of 2 of these studies demonstrated improvement in pain up to 4 hours on a 0-to 100-mm visual analog scale for pain (−19.97 mm; 95% confidence interval, −29.02 to −10.91; P < 0.000).Five trials reported a moderate reduction in cumulative opioid use within 24 hours after vaginal surgery for both paracervical block and uterosacral infiltration. Meta-analysis was not performed for paracervical block because only 1 trial provided suitable data for pooling. Meta-analysis pooling the results of 2 trials of uterosacral infiltration demonstrated opioid consumption of 20.73 morphine milligram equivalents less compared with controls (95% confidence interval, −23.54 to −17.91; P < 0.000).
BackgroundBackground: Gangliosides are expressed in neuronal membranes, and play roles in neuronal differentiation and cell regulation during brain development. The ST3GAL5 gene encodes the enzyme GM3 synthase, and its deficiency causes a rare condition described to cause refractory epilepsy, profound intellectual disability, quadriplegia, choreoathetosis, and pigmentary skin changes. GM3 synthase deficiency is rarely reported to cause dystonia. We report five cases of GM3 synthase deficiency involving a dystonic phenotype. Cases Cases: The five reported individuals were born of unaffected consanguineous parents from Old Order Amish families. They all developed refractory epilepsy and developmental regression within the first few months of life. They exhibit variable degrees of extrapyramidal movements, including orofacial, cervical, and limb dystonia, as well as choreoathetosis. Conclusions Conclusions: We report five individuals with GM3 synthase deficiency who developed dystonic features. Dystonia has previously been reported in only one case of GM3 synthase deficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
