RESUMO
Robotic assisted partial nephrectomy (RPN) has emerged in urologic practice for the management of appropriately sized renal masses. We provide a 20-year comparison of the outcomes of open partial nephrectomy (OPN) versus RPN for renal cell carcinoma (RCC) at our institution. An IRB-approved retrospective review was conducted of RCC patients at a single institution from 2000 to 2022 who underwent RPN or OPN. In addition to demographics, procedural details including ischemia and operative time were collected. Oncologic outcomes were evaluated through Kaplan-Meier statistical analysis to determine recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) analysis. 849 patients underwent RPN while 385 underwent OPN. 61% were male with average age of 58.8 ± 12.8 years. Operative time was shorter in the open group (184 vs 200 min, p = 0.002), as was ischemia time (16 vs 19 min, p = 0.047). However, after 2012, RPN became more common than OPN with improving ischemia time. RPN patients had significantly improved RFS (HR 0.45, p = 0.0004) and OS (HR 0.51, p = 0.0016) when controlled for T-stage and margin status. More > pT1 masses were managed with OPN than RPN (11.2 vs 5.4%, p < 0.0001). At our institution, RPN had an increasing incidence with reduced ischemia time compared to OPN over the last 10 years. While higher stage renal masses were more often managed with OPN, selective use of RPN does offer improved oncologic outcomes. Further investigation is needed to evaluate optimization of the selection of RPN versus OPN in the nephron-sparing management of renal masses.

PURPOSE: Survivors of surgically managed prostate cancer may experience urinary incontinence and erectile dysfunction. Our aim was to determine if 68Ga-prostate-specific membrane antigen-11 positron emission tomography CT (PSMA-PET) in addition to multiparametric (mp) MRI scans improved surgical decision-making for nonnerve-sparing or nerve-sparing approach. MATERIALS AND METHODS: We prospectively enrolled 50 patients at risk for extraprostatic extension (EPE) who were scheduled for prostatectomy. After mpMRI and PSMA-PET images were read for EPE prediction, surgeons prospectively answered questionnaires based on mpMRI and PSMA-PET scans on the decision for nerve-sparing or nonnerve-sparing approach. Final whole-mount pathology was the reference standard. Sensitivity, specificity, positive predictive value, negative predictive value, and receiver operating characteristic curves were calculated and McNemar's test was used to compare imaging modalities. RESULTS: The median age and PSA were 61.5 years and 7.0 ng/dL. The sensitivity for EPE along the posterior neurovascular bundle was higher for PSMA-PET than mpMRI (86% vs 57%, P = .03). For MRI, the specificity, positive predictive value, negative predictive value, and area under the curve for the receiver operating characteristic curves were 77%, 40%, 87%, and 0.67, and for PSMA-PET were 73%, 46%, 95%, and 0.80. PSMA-PET and mpMRI reads differed on 27 nerve bundles, with PSMA-PET being correct in 20 cases and MRI being correct in 7 cases. Surgeons predicted correct nerve-sparing approach 74% of the time with PSMA-PET scan in addition to mpMRI compared to 65% with mpMRI alone (P = .01). CONCLUSIONS: PSMA-PET scan was more sensitive than mpMRI for EPE along the neurovascular bundles and improved surgical decisions for nerve-sparing approach. Further study of PSMA-PET for surgical guidance is warranted in the unfavorable intermediate-risk or worse populations. CLINICALTRIALS.GOV IDENTIFIER: NCT04936334.

Pathogenic CACNA1A gene variants are associated with a spectrum of disorders including migraine with or without hemiplegia, ataxia, epilepsy, and developmental disability. We present a case of a pathogenic variant (c.4046G>A, p.R1349Q) in the CACNA1A gene associated with a clinical phenotype of global developmental delay, left hemiparesis, epilepsy, and stroke-like episodes. Longitudinal neuroimaging demonstrates hemispheric encephalomalacia with mismatched perfusion and angiographic imaging, in addition to progressive cerebellar atrophy.
RESUMO
INTRODUCTION: Obstructive sleep apnea (OSA) in young children is caused by upper airway obstruction and is associated with changes in cognitive development, temperament and behavior. Adenotonsillectomy (AT) is often utilized as first line therapy for pediatric OSA. Children with laryngomalacia (LM) have a high chance of residual OSA after AT. There is paucity of literature regarding surgically naïve young children with OSA and laryngomalacia. Our study aimed to compare demographics, comorbidities and outcomes associated with OSA in surgically naïve young children with and without laryngomalacia. METHODS: Retrospective chart review of surgically naïve young children (<2-year-old) with polysomnogram (PSG) diagnosed OSA. All young children underwent pre-operative PSG followed by drug-induced sleep endoscopy (DISE) directed intervention. Variables documented included demographics, comorbidities, history of adenotonsillectomy, DISE directed surgical interventions and pre and post PSG findings. Laryngomalacia was defined as presence of obstruction (Chan Parikh score ≥ 2) at the supraglottic level on DISE evaluation. Demographics and prevalence of comorbidities of those with and without LM were compared using t-test (continuous) and Chi Square (categorical). P value is significant for <0.05. RESULTS: 79 surgically naïve young children with PSG diagnosed OSA performed between 2015 and 2019 were included in the study. Children with LM were younger in age (11 months) and had a higher OSA-18 score (35) compared to children without LM (17 months) (OSA-18 score: 5). No significant difference was noted in the pre-DISE PSG parameters in the 2 groups. 56.1% of children with OSA and laryngomalacia did not need AT. Both children with and without laryngomalacia showed improvement in AHI on post-DISE PSG. Higher baseline AHI was associated with greater improvement in AHI. CONCLUSION: Surgically naïve young children with OSA and LM present earlier than those without LM and report a significantly worse quality of life Young children with a higher baseline AHI were found to have greater improvement in severity of OSA post-DISE and surgical intervention. Majority of children with OSA and laryngomalacia did not need adenotonsillectomy after a preprocedural DISE assessment yet showed similar improvement in AHI. More studies are needed to determine which patients with OSA and laryngomalacia will need multilevel interventions.
