The notion of physical activity during pregnancy has gained substantial momentum over the recent years. This is likely due to the increasing number of studies that have shown what the benefits exercise can have during this unique time in a woman's life. Pregnancy no longer needs to be thought of as a time to cease all activity, and it is important to counsel patients that there can be increased complications by not exercising. The goal of this chapter is to discuss the specific considerations and recommendations of exercise during pregnancy.

Purpose: This study investigated the involvement of NF-kB in regulating postoperative conjunctival inflammation.Methods: Experimental surgery was performed as described for the mouse model of conjunctival scarring. Expression of NF-κB in postoperative conjunctival tissues or conjunctival fibroblasts were assessed by real-time PCR, immunoblotting and immunofluorescence analyses. Downregulation of RelB was achieved using small interfering RNA. Cellular cytokine secretion was determined using multiplex cytokine assay.Results: RelB was the most highly induced member of the NF-kB family on day 2 post-surgery. Elevated RelB may be found associated with vimentin-positive cells and fibroblasts in vivo and in vitro. In conjunctival fibroblasts, RelB may be induced by TNF-α but not TGF-β2 while its silencing caused selective induction of CCL2 secretion by both basal and TNF-α-stimulated fibroblasts.Conclusions: High RelB induction in the inflammatory phase and the selective modulation of CCL2 suggest a specific anti-inflammatory role for RelB in the postoperative conjunctiva.

OBJECTIVE To investigate intrathecal inflammation using cerebrospinal fluid (CSF) cytokines and chemokines in a subgroup of pediatric epilepsy patients with frequent daily seizures. METHODS We measured 32 cytokines/chemokines using multiplex immunoassay in CSF collected from pediatric patients with febrile infection-related epilepsy syndrome (FIRES)/FIRES-related disorders (FRD; n = 6), febrile status epilepticus (FSE; n = 8), afebrile status epilepticus (ASE; n = 8), and chronic epilepsy with frequent daily seizures (n = 21) and compared the results with noninflammatory neurological disorders (NIND; n = 20) and encephalitis (n = 43). We also performed longitudinal CSF cytokine/chemokine studies in three cases with FIRES/FRD. RESULTS The median age of onset of seizures was 2.4 years (range = 0.08-12.5). Median CSF timing from the onset of seizures was longer in chronic epilepsy (540 days), whereas FIRES, FSE, and ASE had CSF tested within 1-2 days of onset of seizures (P < .001). The elevation of cytokines/chemokines was higher in FIRES followed by FSE, when compared to chronic epilepsy and NIND controls. Th1-associated cytokines/chemokines (TNF-α, CXCL9, CXCL10, CXCL11), IL-6, CCL2, CCL19, and CXCL1 (P

Valproic acid (VPA) is a histone deacetylase inhibitor used clinically for neurological disorders. It is also potentially useful as anti-fibrotic therapy as it reduced collagen deposition in the post-operative conjunctiva. In this study, we further evaluated the effects of VPA on post-operative inflammation using the mouse model of conjunctival scarring. VPA, injected into the subconjunctiva immediately after surgery, did not cause any adverse tissue response when examined by live microscopy and produced an apparent reduction of proinflammatory and proangiogenic markers in immunohistological examinations. In-depth analyses of the treated operated tissues revealed that VPA selectively inhibited the CD45highF4/80low macrophage subset as well as the production of specific proinflammatory cytokines/ chemokines, including CXCL1, IL-5, IL-6, and IL-10 which were reduced by ≥ 2.0-fold. VPA also specifically reduced tissue NF-кB2 p100 protein by mean 3.87-fold. On conjunctival fibroblasts, VPA treatment resulted in decreased secretion of specific cytokines, including CCL2, VEGF-A, and IL-15. In the presence of TNF-α, VPA inhibited the induction of specific cytokines/chemokines, notably CCL5 and VEGF-A, as well as NF-кB2 p100. In corroboration, VPA suppressed TNF-α stimulation of NF-кB reporter transcription by 1.51-fold. These data indicate that VPA can modulate both proinflammatory cellular and molecular targets in a selective manner and may therefore attenuate surgery-induced conjunctival inflammation. These and previous findings suggest that, by suppressing key mediators of both inflammation and fibrosis, VPA is a useful therapeutic for improving surgical outcome involving the conjunctiva. Key messages VPA inhibited recruitment of a CD45highF4/80low macrophage subset. VPA reduced chemokine and cytokine levels in treated tissues.VPA selectively suppressed tissue NF-кB2 p100 levels.VPA suppressed TNF-α induction of chemokines, cytokines and NF-кB2 p100 expression.VPA suppressed TNF-α stimulation of NF-кB reporter.

Purpose To identify the psychological impact of canceling cataract operations on patients during COVID-19 pandemic.Methods 99 participants aged from 59 years old who had their cataract surgeries postponed or as scheduled, were studied using the standardized patient health questionnaire (PHQ-9) and generalized anxiety disorder questionnaire (GAD-7) from April to June 2020 at Kowloon East Cataract Center, Tseung Kwan O Hospital, Hong Kong. ResultsNone of the patients who had the cataract surgeries rescheduled reached the cutoff score for major depression in PHQ-9, whereas for GAD-7, 5 patients had mild symptoms of anxiety, 1 had severe symptoms (p-value = 0.76). Conclusion There was no significant psychosocial impact of cancellation of cataract surgeries on patients.

PurposeTo determine the effect of valproic acid (VPA) on bleb morphology and scar characteristics in a rabbit model of minimally invasive glaucoma surgery (MIGS).MethodsNine New Zealand white rabbits were subjected to MIGS with intraoperative implantation of the PreserFlo MicroShunt. Rabbits were then administered with subconjunctival injections of phosphate buffered saline (PBS) (n=4) or with VPA (n=5). Bleb morphology was examined by slit-lamp biomicroscopy and in vivo confocal microscopy. Postoperative day 28 tissues were examined by immunohistochemical evaluation and label-free multiphoton microscopy to visualise the collagen matrix, by terminal deoxynucleotidyl transferase dUTP nick-end labelling assay and immunofluorescent labelling for Ki67 expression to detect apoptosis and cell growth, and by real-time quantitative PCR to measure Col1a1, Fn, and Smad6 transcript expression.ResultsVPA-treated blebs were detectable on day 28, while the PBS-treated blebs were not detectable by day 14. VPA-treated blebs were diffuse, extended posteriorly with near normal conjunctival vascularity and featured a combination of reticular/blurred stromal pattern with evidence of relatively large stromal cysts. Instead of the deposition of thick, disorganised collagen fibres characteristic of the PBS bleb, the VPA bleb contained conspicuously thinner collagen fibres which were associated with similarly thinner fibronectin fibres. In corroboration, Col1a1 and Fn mRNA expression was reduced in the VPA blebs, while increased Smad6 expression implicated the disruption of the transforming growth factor beta pathway. Apoptosis and cell growth profiles appeared similar with both treatments.ConclusionsThe results support the application of VPA to enhance bleb morphology associated with good bleb function in MIGS with no apparent cytotoxicity.

Aim To determine the role of inflammation in pediatric transient focal cerebral arteriopathy using cerebrospinal fluid cytokine/chemokines as biomarkers. Methods We measured 32 cytokine/chemokines in acute cerebrospinal fluid collected from children with stroke due to focal cerebral arteriopathy (n = 5) using multiplex immunoassay and compared with two patients with arterial ischemic stroke due to other causes (non-focal cerebral arteriopathy group, vertebral dissection, n = 1; cryptogenic, n = 1), pediatric encephalitis (n = 43), and non-inflammatory neurological disease controls (n = 20). Results Median age in the focal cerebral arteriopathy group was 9.3 years (range, 2.8–13 years). In the focal cerebral arteriopathy group (n = 5), four patients had middle cerebral ± distal carotid arteriopathy; one patient had posterior circulation arteriopathy. The median time from symptom onset to cerebrospinal fluid sampling was four days (range, 0.6–7 days). Only IL-6, IL-8, CXCL1, and CXCL10 levels were significantly higher in the acute cerebrospinal fluid of focal cerebral arteriopathy patients compared to non-inflammatory neurological disease controls and non-focal cerebral arteriopathy stroke. In contrast to focal cerebral arteriopathy, a broad array of Th1, Th2, Treg, Th17, B-cell related, and other broad spectrum cytokine/chemokines were elevated in encephalitis. Conclusion The elevated cerebrospinal fluid cytokine/chemokines support innate, T cell, and granulocyte inflammatory mechanisms in children with focal cerebral arteriopathy. This warrants larger cohort studies to discriminate primary inflammatory signals of the arteriopathy from secondary inflammation due to the stroke itself.

BackgroundTo develop targeted antifibrotic therapy for glaucoma filtration surgery; this study determines the effectiveness of small interfering RNA (siRNA) to reduce in vivo secreted protein acidic and rich in cysteine (SPARC) expression using the mouse model of conjunctival scarring.MethodsExperimental surgery was performed as described for the mouse model of conjunctival scarring. Scrambled (siScram) or Sparc (siSparc) siRNAs, loaded on layer-by-layer (LbL) nanoparticles, were injected into the conjunctiva immediately after surgery. Expression ofSparc,Col1a1,Fn1andMmp14was measured by real-time PCR and immunoblotting on days 7 and 14 postsurgery. Live imaging of the operated eyes was performed using slit lamp, anterior segment-optical coherence tomography and confocal microscopy. Tissue pathology was evaluated by histochemical and immunofluorescent analyses of operated conjunctival cryosections. Tissue apoptosis was quantitated by annexin V assay.Results siSparc, delivered via expanded LbL nanoparticles, significantly inhibitedSparctranscription in both day 7 (2.04-fold) and day 14 (1.39-fold) treated tissues.Sparcsuppression on day 7 was associated with a significant reduction ofCol1a1(2.52-fold),Fn1(2.89-fold) andMmp14(2.23-fold) mRNAs. At the protein level, both SPARC and collagen 1A1 (COL1A1) were significantly reduced at both time points with siSparc treatment. Nanoparticles were visualised within cell-like structures by confocal microscopy, while overt tissue response or apoptosis was not observed.Conclusions SPARC targeted therapy effectively reduced both SPARC and collagen production in the operated mouse conjunctiva. This proof-of-concept study suggests that targeted treatment of fibrosis in glaucoma surgery is safe and feasible, with the potential to extend to a range of potential genes associated with fibrosis.

An acute care pediatric hospital and a university school of nursing joined forces to develop a comprehensive, interactive, online course in pediatric health assessment. The course was intended to increase nurses' knowledge and confidence in caring for children and families. The need for pediatric health assessment education varies depending on learners' prior experience. This article describes the course development and shares insights into the successful health care-academic partnership, which combined clinical, scholarly, and technological expertise.

Introduction We examined provider and regional variation in services provided and payments made to urologists by CMS (Centers for Medicare & Medicaid Services) by linking payments to individual beneficiaries and examining the proportion of submitted charges resulting in payments. Methods We analyzed Medicare Part B Provider Utilization and Payment Data released by CMS for 2012, the last year of the purely fee-for-service reimbursement model. For each provider we determined the ratio of number of services provided to individual beneficiaries as well as the ratio of total submitted charges-to-total Medicare payments. Each provider was stratified into deciles of total Medicare payments and the mean per decile of total Medicare payment was calculated. Finally, to elucidate the potential association between the ratio of services-to-beneficiaries, we conducted multivariate linear regressions. Results The 20th, 40th, 60th and 80th percentiles for the ratio of number of services per individual beneficiary ratios to total Medicare Part B payments are 2.8, 4.0, 5.2 and 7.4, respectively. Urologists with greater payments received provided more services to individual beneficiaries. Submitted charges exceeded payments by 3:1. Finally, female providers had lower ratios (p Conclusions We found significant variation in services and payment in CMS. Reimbursement models replacing fee-for-service should be tailored to ensure appropriate health care resource utilization.

To examine initial and longitudinal health-related quality of life (HRQOL) in adolescent sports-related concussion (SRC) patients, a prospective observational case-series study was conducted among adolescent SRC patients who were evaluated at a multi-disciplinary pediatric concussion program. Health-related quality of life was measured using the child self-report Pediatric Quality of Life Inventory (PedsQL) generic score scale (age 13-18 version) and the PedsQL Cognitive Functioning scale. Initial and longitudinal HRQOL outcomes were compared between patients who did and did not develop post-concussion syndrome (PCS). A total of 63 patients met the inclusion criteria during the study period. The mean age of the cohort was 14.57 years (standard deviation, 1.17) and 61.9% were male. The median time from injury to initial consultation was 6.5 days (interquartile range, 5, 11). At initial consultation, impairments in physical and cognitive HRQOL but not social or emotional HRQOL were observed. Initial symptom burden and length of recovery were associated with greater impairment in physical and cognitive HRQOL. Patients who went on to develop PCS had significantly worse physical and cognitive HRQOL at initial consultation and demonstrated a slower rate of recovery in these domains, compared with those who recovered in less than 30 days. Adolescent SRC was associated with HRQOL impairments that correlated with clinical outcomes. No persistent impairments in HRQOL were detected among patients who achieved physician-documented clinical recovery. Future studies are needed to evaluate the clinical utility of HRQOL measurement in the longitudinal management of adolescent SRC and PCS patients.

BACKGROUND: Concussion is an emerging public health concern, but care of patients with a concussion is presently unregulated in Canada. METHODS: Independent, blinded Google Internet searches were conducted for the terms "concussion" and "concussion clinic" and each of the Canadian provinces and territories. The first 10 to 15 concussion healthcare providers per province were identified. A critical appraisal of healthcare personnel and services offered on the provider's Web site was conducted. RESULTS: Fifty-eight concussion healthcare providers were identified using this search methodology. Only 40% listed the presence of an on-site medical doctor (M.D.) as a member of the clinical team. Forty-seven percent of concussion healthcare providers advertised access to a concussion clinic, program, or center on their Web site. Professionals designated as team leaders, directors, or presidents among concussion clinics, programs, and centers included a neuropsychologist (15%), sports medicine physician (7%), neurologist (4%), and neurosurgeon (4%). Services offered by providers included baseline testing (67%), physiotherapy (50%), and hyperbaric oxygen therapy (2%). CONCLUSIONS: This study indicates that there are numerous concussion healthcare providers in Canada offering diverse services with clinics operated by professionals with varying levels of training in traumatic brain injury. In some cases, the practices of these concussion clinics do not conform to current expert consensus guidelines. Language: en

IFIH1 gain-of-function causes a spectrum of neuroinflammatory phenotypes associated with enhanced type I interferon production and Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway activation.1,2 Patients most often present in infancy, variably exhibiting spasticity, dystonia, seizures, and acquired microcephaly. We report the use of ruxolitinib, a JAK 1/2 blocker, in the treatment of early-onset, progressive neurologic disease due to an IFIH1 mutation.

Purpose Aquaporins (AQPs) facilitate transmembrane osmotic water transport and may play a role in iris fluid conductivity, which is implicated in the pathophysiology of glaucoma. In this study, we compared the iris expression of AQPs and aqueous osmolality between primary angle closure glaucoma (PACG), primary open-angle glaucoma (POAG), and nonglaucoma eyes. Methods AQP1-5 transcripts from a cohort of 36 PACG, 34 POAG and 26 nonglaucoma irises were measured by quantitative real-time PCR. Osmolality of aqueous humor from another cohort of 49 PACG, 50 POAG, and 50 nonglaucoma eyes were measured using an osmometer. The localization of AQP1 in both glaucoma and nonglaucoma irises was determined by immunofluorescent analysis. Results Of the five AQP genes evaluated, AQP1 and AQP2 transcripts were significantly upregulated in both PACG (3.48- and 8.07-fold, respectively) and POAG (3.12- and 11.58-fold, respectively) irises relative to nonglaucoma counterparts. The aqueous osmolalities of PACG (303.68 mmol/kg) and POAG (300.79 mmol/kg) eyes were significantly lower compared to nonglaucoma eyes (312.6 mmol/kg). There was no significant difference in expression of AQP transcripts or aqueous osmolality between PACG and POAG eyes. Conclusions PACG and POAG eyes featured significant increase in AQP1 and AQP2 expression in the iris and reduced aqueous osmolality compared to nonglaucoma eyes. These findings suggest that the iris may be involved in altered aqueous humor dynamics in glaucoma pathophysiology. Because PACG did not differ from POAG in both properties studied, it is likely that they are common to glaucoma disease in general.

Glaucoma filtration surgery (GFS) commonly fails due to excessive fibrosis. As collagen structure aberrations is implicated in adverse fibrotic progression, this study aims to uncover collagen organization alterations during postoperative scarring. Via quantitative second harmonic generation/ two photon excitation multiphoton imaging, we reveal the scar development and phenotype in the mouse model of conjunctival scarring. We also show that multiphoton imaging corroborated the collagen ultrastructure anomaly characteristic of the SPARC-/- mouse postoperative conjunctiva. These data improve our understanding of postoperative conjunctival scarring and further enhance the utility of this model for the development of anti-fibrotic therapeutics for GFS.

Objective To report the use of telemedicine to deliver general urologic care to remote locations within the Veterans Affairs Greater Los Angeles Healthcare System. We describe the diagnoses managed, patient satisfaction, safety, and benefit to patients in terms of saved travel time and expense. Methods We conducted a retrospective chart review examining care delivered through urology telemedicine clinics over a 6-month period. We examined the urologic conditions, patient satisfaction, and emergency department visits within 30 days of the visit. We estimated patient benefit by calculating travel distance and time and the saved travel-associated costs using Google Maps and US Census income data. Results Ninety-seven unique telemedicine visits were conducted and a total of 171 urologic diseases were assessed. The most common conditions were lower urinary tract symptoms (35%), elevated prostate-specific antigen level (15%), and prostate cancer (14%). One patient was seen in the emergency department within 30 days with an unpreventable urologic complaint. Patient satisfaction was “very good” to “excellent” in 95% of cases, and 97% would refer another veteran to the urology telemedicine clinic. Patients saved an average of 277 travel miles, 290 minutes of travel time, $67 in travel expenses, and $126 in lost opportunity cost. Conclusion Telemedicine was successfully and safely used to evaluate and treat a wide range of urologic conditions within the Veterans Affairs Greater Los Angeles Healthcare System, and saves patients nearly 5 hours and up to $193 per visit. Further investigation of the potential of telemedicine for the delivery of urologic care in a cost-effective manner is warranted.

Objectives The objectives of this study are to better understand women's experience with pelvic organ prolapse (POP) and to compare this experience between English-speaking and Spanish-speaking women. Methods Women with POP were recruited from female urology and urogynecology clinics. Eight focus groups of 6 to 8 women each were assembled-4 groups in English and 4 in Spanish. A trained bilingual moderator conducted the focus groups. Topics addressed patients' perceptions, their knowledge and experience with POP symptoms, diagnostic evaluation, physician interactions, and treatments. Results Both English-speaking and Spanish-speaking women expressed the same preliminary themes-lack of knowledge regarding the prevalence of POP, feelings of shame regarding their condition, difficulty in talking with others, fear related to symptoms, and emotional stress from coping with POP. In addition, Spanish-speaking women included fear related to surgery and communication concerns regarding the use of interpreters. Two overarching concepts emerged-first, a lack of knowledge, which resulted in shame and fear and second, public awareness regarding POP is needed. From the Spanish speaking, an additional concept was the need to address language barriers and the use of interpreters. Conclusions Both English-speaking and Spanish-speaking women felt ashamed of their POP and were uncomfortable speaking with anyone about it, including physicians. Educating women on the meaning of POP, symptoms, and available treatments may improve patients' ability to discuss their disorder and seek medical advice; for Spanish-speaking women, access to translators for efficient communication is needed.

Aim: The purpose of this study was to examine academic achievement, absenteeism and school accommodations following adolescent sport-related concussion (SRC). Methods: A case-series was conducted among grade 8–12 students who suffered an SRC. The primary outcomes were change in pre- and post-concussion overall, core report card grade point average (GPA) and absenteeism due to concussion. The most helpful school accommodations were tabulated. Results: Pre- and post-concussion GPA was obtained from 33 students – 16 (48%) developed persistent post-concussion symptoms (symptoms lasting >4 weeks). There was no significant difference in pre- and post-concussion grades among students with a SRC for overall (p = 0.75) or core (p = 0.56) GPA. The median number of missed school days was 4 (interquartile range [IQR]: 2–8). Allowing for physical and cognitive rest was identified as the most helpful accommodation (30%). Conclusion: Larger studies should investigate the role that school accommodations and development of persistent post-concussion symptoms have on academic outcomes.

Failure after glaucoma filtration surgery is attributed to fibrosis at the operated site. To understand the wound healing process after glaucoma filtration surgery, we have developed a mouse model for glaucoma filtration surgery which closely mimics the clinical response. In this study, we describe a systematic analysis of the wound healing response in vivo. Our data revealed that the post-surgical tissue response was separable into two distinguishable phases. The early "acute inflammatory" phase was characterized by significantly increased transcript expression of Vegfa, Cxcl1, Cxcl5, Ccl2, Ccl3, Ccl4, Gmcsf and specific Mmps as well as greater infiltration of monocytes/macrophages and T cells. The late "fibrotic" phase was characterized by an increased expression of Tgfb2 and extracellular matrix genes as well as a notable reduction of infiltrating inflammatory cells. Significantly, more mitotic cells were observed at both time points post-surgery. Subconjunctival fibroblasts may be involved in both phases since they have the capacity to reiterate the in vivo gene expression profiles upon either pro-inflammatory or pro-fibrotic cytokine stimulation. Given that the cellular and molecular targets that govern the early and late phases of wound healing are distinct and time sensitive, a multi-targeted therapeutic approach to sequentially inhibit inflammation and fibrogenesis at the critical time point may lead to improved surgical outcomes in glaucoma filtration surgery.

Our aim was to test the feasibility of a set of quality of care indicators for urinary incontinence and at the same time measure the care provided to women with urinary incontinence in 2 clinical settings.This was a pilot test of a set of quality of care indicators. A total of 20 quality of care indicators were previously developed using the RAND Appropriateness Method. These quality of care indicators were used to measure care received for 137 women with a urinary incontinence diagnosis in a 120-physician hospital based multispecialty medical group. We also performed an abstraction of 146 patient records from primary care offices in Southern California. These charts were previously used as part of ACOVE (Assessing Care of Vulnerable Elders Project). As a post-hoc secondary analysis, the 2 populations were compared with respect to quality, as measured by compliance with the quality of care indicators.In the ACOVE population, 37.7% of patients with urinary incontinence underwent a pelvic examination vs 97.8% in the multispecialty medical group. Only 15.6% of cases in the multispecialty medical group and 14.2% in ACOVE (p = 0.86) had documentation that pelvic floor exercises were offered. Relatively few women with a body mass index of greater than 25 kg/m(2) were counseled about weight loss in either population (20.9% multispecialty medical group vs 26.1% ACOVE, p = 0.76). For women undergoing sling surgery, documentation of counseling about risks was lacking and only 9.3% of eligible cases (multispecialty medical group only) had documentation of the risks of mesh.Quality of care indicators are a feasible means to measure the care provided to women with urinary incontinence. Care varied by population studied and yet deficiencies in care were prevalent in both patient populations studied.

Systematic study of outcomes of initial surgery for primary hyperparathyroidism (PHPT) has been limited by selection and self-reporting biases. To avoid these biases, we evaluated parathyroidectomy (PTx) outcomes within an integrated health care system encompassing 3.25 million enrollees.All patients undergoing PTx for PHPT from 1995 to 2010 were studied. Persistent and recurrent disease were defined by a serum calcium level10.5 mg/dL before or after 6 months postoperatively, respectively. The effect of demographic, clinical, and hospital volume-related variables was assessed by the use of multivariate logistic regression.A total of 1,190 initial operations for PHPT were performed at 14 hospitals. Follow-up calcium levels were available in 97% of subjects. The overall success rate was 92%, and 5% of patients developed recurrent disease. Age ≥ 70 years was predictive of persistent disease (odds ratio 1.80, P.05). High-volume hospital (100 cases) predicted against persistent disease (odds ratio 0.42, P.05) and carried 96% success rate. Negative or equivocal sestamibi scan was associated with a lower success rate (success rate 89% vs 95% for positive scan, P.05). Reoperation was performed in 12% of patients with persistent or recurrent PHPT.The success rate of PTx is influenced by patient age, hospital volume, and sestamibi scan result. Surgical outcomes may be optimized by designating high-volume centers in the community setting.

Transitional cell carcinoma (TCC) is extremely rare in children, with fewer than 30 cases reported in patients under 10 years old. It is thought that pediatric TCC is fundamentally different than TCC in adults; however, there are no specific guidelines for management or surveillance. Furthermore, the addition of papillary urothelial neoplasm of low malignant potential as a diagnosis has changed the management of lesions previously considered malignant. This review aims to investigate the difference between TCC in adults and children, to report current strategies for management of pediatric TCC, and to analyze the effects of the new grading system.

OBJECT The objectives of this study were twofold: 1) to examine the prevalence of emotional symptoms among children and adolescents with a sports-related concussion (SRC) who were referred to a multidisciplinary pediatric concussion program and 2) to examine the prevalence, clinical features, risk factors, and management of postinjury psychiatric outcomes among those in this clinical population. METHODS The authors conducted a retrospective chart review of all patients with SRC referred to a multidisciplinary pediatric concussion program between September 2013 and October 2014. Clinical assessments carried out by a single neurosurgeon included clinical history, physical examination, and Post-Concussion Symptom Scale (PCSS) scoring. Postinjury psychiatric outcomes were defined as a subjective worsening of symptoms of a preinjury psychiatric disorder or new and isolated suicidal ideation or diagnosis of a novel psychiatric disorder (NPD). An NPD was defined as a newly diagnosed psychiatric disorder that occurred in a patient with or without a lifetime preinjury psychiatric disorder after a concussion. Clinical resources, therapeutic interventions, and clinical and return-to-play outcomes are summarized. RESULTS One hundred seventy-four patients (mean age 14.2 years, 61.5% male) were included in the study. At least 1 emotional symptom was reported in 49.4% of the patients, and the median emotional PCSS subscore was 4 (interquartile range 1–8) among those who reported at least 1 emotional symptom. Overall, 20 (11.5%) of the patients met the study criteria for a postinjury psychiatric outcome, including 14 patients with an NPD, 2 patients with isolated suicidal ideation, and 4 patients with worsening symptoms of a preinjury psychiatric disorder. Female sex, a higher initial PCSS score, a higher emotional PCSS subscore, presence of a preinjury psychiatric history, and presence of a family history of psychiatric illness were significantly associated with postinjury psychiatric outcomes. Interventions for patients with postinjury psychiatric outcomes included pharmacological therapy alone in 2 patients (10%), cognitive behavioral therapy alone in 4 (20%), multimodal therapy in 9 (45%), and no treatment in 5 (25%). Overall, 5 (25%) of the patients with postinjury psychiatric disorders were medically cleared to return to full sports participation, whereas 5 (25%) were lost to follow-up and 9 (45%) remained in treatment by the multidisciplinary concussion program at the end of the study period. One patient who was asymptomatic at the time of initial consultation committed suicide. CONCLUSIONS Emotional symptoms were commonly reported among pediatric patients with SRC referred to a multidisciplinary pediatric concussion program. In some cases, these symptoms contributed to the development of an NPD, isolated suicidal ideation, and worsening symptoms of a preexisting psychiatric disorder. Future research is needed to clarify the prevalence, pathophysiology, risk factors, and evidence-based management of postinjury psychiatric outcomes after pediatric SRC. Successful management of these patients requires prompt recognition and multidisciplinary care by experts with clinical training and experience in concussion and psychiatry.

INTRODUCTION AND OBJECTIVES: Robotic surgery has a variable learning curve with multiple factors potentially affecting operative times. We sought to measure the effect of patient, provider, and system-related variables on operative time. METHODS: Retrospective data was collected over a 3.5 year period on 1,099 patients undergoing 11 robotic surgeries by 23 urologists and gynecologists at Cedars-Sinai Medical Center in Los Angeles. Data included patient age, BMI, comorbidities, operative time, surgeon volume, and type of robot (da Vinci Standard vs da Vinci S System). Analyses were performed by linear regression modeling. RESULTS: Average procedure time was 4.87 þ/1.33 hours. Surgeons performed an average of 49 þ/83 surgeries (range 1 to 362, median 1⁄4 8). The upper 25th percentile of surgeons by volume performed 60 or more procedures, and the lower 25th percentile performed four or less. Patients with 25 30) was 0.35 þ/0.08 hours longer vs BMI < 25 (p < 0.001). Diabetes was also associated with increased procedure time, but age and heart disease were not. After performing a subset analysis of surgeons who performed 20 or more surgeries (n 1⁄4 10), the average procedure time for the first 10 surgeries was 4.82 þ/2.83 hours and for the last 10 was 5.03 þ/2.90 hours. The upper (n1⁄45) and lower (n1⁄46) 25th percentile of surgeons had an average procedure time of 5.31 þ/0.74 hours and 4.36 þ/0.77 hours, respectively (p 1⁄4 0.067). After accounting for covariates such as robot type and BMI, high volume surgeons took 0.90 þ/0.44 hours longer than low volume surgeons (p1⁄40.042). The average time for the da Vinci Standard was 4.70 þ/1.12 hours (n1⁄4639 procedures) and for the da Vinci S was 5.10 þ/1.55 hours (n1⁄4493 procedures) (p < 0.001). After accounting for surgeon volume, BMI, department and procedure type, the first generation da Vinci Standard had procedure times 0.35 þ/0.08 hours shorter than the second generation da Vinci S (p < 0.001). CONCLUSIONS: Unexpectedly, surgeon operative times did not tend to improve over time, and operative times were not significantly different between high and low volume surgeons. Also surprisingly operative times were not faster with the newer generation da Vinci model. After overcoming learning curves, surgeons may have an inherent “pace” that dictates their operative time.

Slip progression after in situ screw fixation is rarely reported and its true incidence is unknown. Greater than five threads across the physis is the only known factor to minimize slip progression after in situ screw fixation. The purpose of this study was to determine the incidence of continued slip progression after in situ screw fixation and identify potential …

We present the case of a 12-year-old boy with acute urinary retention presumed secondary to Epstein-Barr virus infection. Workup revealed an atonic bladder, which was refractory to medical management. The patient subsequently developed axillary lymphadenopathy, and the biopsy specimen was consistent with Epstein-Barr virus. In addition to presenting this patient with acute urinary retention secondary to EBV infection, we review the causes of acute urinary retention in children, with a focus on viral etiologies.

No evidence-based Return-To-Learn program is available to help students return to school after a concussion. The objective was to examine the relationship between health-related quality of life (HRQoL), symptom severity, and school functioning in students with a sport-related concussion. This prospective case-series was conducted with students (13–18 years) who presented to the Pan Am Concussion Program in Winnipeg, Canada and were diagnosed with an acute sport-related concussion by a neurosurgeon. At each appointment, students completed the Post-concussion Symptom Severity (PCSS) scale, PedsQL 4.0 (physical, social, school, emotional functioning domains) and cognitive functioning. They received a log book to track school attendance. At medical clearance, exit interviews were conducted to examine the impact of their concussion on academics and HRQoL. Fifty-four students (57% male) were diagnosed with an acute-sport related concussion. Students initially presented with median PCSS score of 19 (IQR: 8, 34) and had poorest HRQoL in the physical and cognitive domains. At each medical appointment, PCSS score decreased by 6.3 points (95% CI: −7.6, −4.9). All HRQoL domains significantly improved over time; however, mean cognitive functioning scores remained the lowest at medical clearance (75.0; SD:3.8). There was no significant difference in median days to medical clearance among students who rated their school accommodations as poor (n = 8) compared with those who rated them as good (n = 20) (19 vs. 27 days; p = 0.42). Students missed a median of 7 days of school and returning to Math (16/27, 59%) and Science (14/29, 48%) was the most difficult. Concussion symptoms and all domains of HRQoL improve over time. Yet cognitive functioning scores (attention, remembering, and thinking) remain low after medical clearance and this could affect academic performance. This study provides evidence documenting students’ struggles when recovering from their concussion and returning to school. This information can help form a Return-To-Learn program.
