RESUMEN
STUDY OBJECTIVE: Temporary urinary retention after midurethral sling (MUS) surgery requiring indwelling catheter or self-catheterization usage is common. Different methods for assessment of immediate postoperative urinary retention have been described. This study aimed to compare postoperative voiding trial (VT) success after active vs passive VT in women undergoing MUS surgery. DESIGN: Comparative retrospective cohort study. SETTING: Female pelvic medicine and reconstructive surgery practice at a university-affiliated tertiary medical center. PATIENTS: Patients with stress urinary incontinence who underwent surgical treatment during the study period were eligible for inclusion. Excluded were patients younger than the age of 18 years, combined cases with other surgical services, planned laparotomy, and a history of urinary retention and patients for whom their VT was performed on postoperative day 1. The cohort was divided into 2 groups: (1) patients who underwent an active retrofill of their bladder using a Foley catheter and (2) patients who were allowed to have a spontaneous void. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 285 patients met the inclusion criteria for the study. Of these subjects, 94 underwent an active VT and 191 underwent a passive VT. There were no statistically significant differences in immediate postoperative urinary retention (30.8% vs 29.3%; p = .79) or time from surgery end to VT (233.0 ± 167.6 minutes vs 203.1 ± 147.8 minutes; p = .13) between groups. Urinary retention, as defined by a failed VT, increased from 10% to 29.3% when MUS placement was accompanied by concomitant prolapse repair procedure. Multivariate logistic regression analysis revealed that undergoing a combined anterior and posterior colporrhaphy (odds ratio [OR], 5.13; p <.001) and undergoing an apical prolapse procedure (OR, 2.75; p = .004) were independently associated with immediate postoperative urinary retention whereas increased body mass index (OR, 0.89; p <.001) lowered likelihood of retention. CONCLUSION: The method used to assess immediate postoperative urinary retention did not affect VT success. Concomitant combined anterior and posterior colporrhaphy and apical suspension were correlated with greater likelihood of VT failure whereas increased body mass index decreased odds of retention.

BACKGROUND: Lateral meningocele syndrome (LMS) is an exceedingly rare connective tissue disease with phenotypic anomalies similar to those seen in Marfan syndrome, Ehler-Danlos syndrome, and Loeys-Dietz syndrome. However, this syndrome is invariably associated with the presence of multiple lateral thoracolumbar spinal meningoceles: a distinct point of phenotypic divergence from other connective tissue disorders. The etiopathogenesis of this syndrome has recently been linked to truncating mutations within exon 33 of NOTCH3. Despite numerous reports, neurosurgical management of multiple spinal meningoceles remains poorly defined in the literature. We conducted a literature review to provide insight into the nosology, clinical significance, and neurosurgical management strategies of this distinct connective tissue disorder. SUMMARY: Our literature search revealed 11 articles (16 cases) of LMS, which included 9 males and 7 females, belonging to 14 different families. Half of these cases underwent genetic screening: all of which were discovered to exhibit a truncating mutation within exon 33 of NOTCH3. All patients exhibited multiple lateral thoracolumbar spinal meningoceles with craniofacial dysmorphisms. Other clinical characteristics included pathologic changes in spine morphology, Chiari I malformation, syringomyelia, hydrocephalus, and tethered cord. Operative management of multiple spinal meningoceles in LMS is complicated by the presence of such coexisting structural neurologic pathologies, which may alter cerebrospinal fluid flow dynamics and, ultimately, impact operative intervention. Key Messages: LMS is an exceedingly rare connective tissue disorder with severe spinal dural involvement. Neurosurgical management of multiple spinal meningoceles is complex, which is further complicated by the presence of coexisting neuropathology, such as pathologic transformation of spine morphology and Chiari I malformation. Patients with a connective tissue disorder phenotype found to have multiple spinal meningoceles on imaging studies may benefit from evaluation by a medical geneticist and a pediatric neurosurgeon.

â¢Methotrexate (MTX) hypersensitivity is rare and has not been widely reported in the setting of treatment of GTN.â¢Work up of hypersensitivity reactions may include consultation to an allergist, serum tryptase level, and possible skin testing.â¢In low-risk GTN, dactinomycin should be utilized after a hypersensitivity reaction to MTX.
RESUMEN
Treatment of brain metastases often includes surgical resection, chemotherapeutics and radiotherapy. Given the difficulty in obtaining therapeutic levels of medications within the immune-privileged central nervous system, chemotherapy as a stand-alone treatment modality for brain metastases is an uncommon option. However, there is a growing body of evidence to suggest that immunomodulatory agents can induce a robust immune response in the central nervous system. Here, we describe a 68-year old male who presented with radiographic evidence of new and enlarging lung nodules with mediastinal adenopathy. Lung biopsy was consistent with adenocarcinoma. Immunohistochemical staining demonstrated high expression of programmed cell death protein 1 with a tumor proportion score of 100%. Surveillance magnetic resonance imaging of the brain demonstrated a single enhancing 11 × 7 × 12 mm lesion along the mesial surface of the right frontal lobe. The patient deferred surgical resection as well as stereotactic radiosurgery but agreed to treatment with pembrolizumab. Repeat magnetic resonance imaging at 3-months after initiation of treatment demonstrated complete radiographic resolution of the brain lesion. To our knowledge, this is one of only a few reports in the current literature to document complete resolution of non-small cell lung cancer brain metastasis with pembrolizumab alone. We discuss the emerging literature regarding the efficacy of pembrolizumab in the treatment of brain metastases, central nervous system penetration, and emerging new treatment paradigms involving novel immunotherapy agents.
RESUMEN
BACKGROUND: Recent studies have reported a gender and medical degree disparity for those receiving Research Project Grants in surgical specialties. The aim of the present study is to analyze factors among academics neurosurgeons that correlate to higher amounts of R01 grant monies awarded. MATERIALS AND METHODS: The National Institutes of Health Research Portfolio Online Reporting Tools Expenditures and Results database was queried for neurosurgery funding between 2008 and 2018. Grant recipients were categorized among type of degree, secondary degree(s), professorship, gender, and h - index. Statistical analysis was performed. RESULTS: The National Institutes of Health awarded 480 R01 grants totaling $182,482,644 to 81 allopathic neurosurgeons between 2008 and 2018. No osteopathic neurosurgeons were awarded an R01 grant during this timeframe. There was a significant difference for type of professorship on the total awarded amount at the p < 0.05 level for the three types of professorship [F (2,78) = 4.85, p < 0.01)]. There was a significant difference for magnitude of h - index on total R01 monies (p < 0.00001). Males accounted for the majority of R01 monies (93.99%); however, no significant difference between average amount awarded and gender was identified (p = 0.86). A secondary degree was without significant difference for R01 amount awarded (p = 0.75). CONCLUSIONS: The present study establishes a medical degree disparity for academic neurosurgeons who receive an R01 grant. Statistically significant factors found to affect amount of R01 grant monies awarded were limited to type of professorship and magnitude of h - index.
RESUMEN
Rapidly fatal encephalitis associated with atypical lymphoid proliferations after intracranial aneurysm rupture has not been reported. Here, we describe a 52-year-old female who presented to the emergency department with a severe headache. Imaging demonstrated aneurysmal subarachnoid hemorrhage due to a ruptured left posterior inferior cerebellar artery aneurysm, which was treated with endovascular embolization and subsequent external ventricular drain. She recovered without neurologic sequelae by day seven; however, five weeks later she represented with a severe headache associated with nausea and fever. Initial repeat imaging was unremarkable. She deteriorated quickly and was empirically treated for meningitis despite negative cerebrospinal fluid studies. Magnetic resonance imaging revealed diffuse cerebral edema within the basal ganglia and thalamus. Biopsy of the caudate nuclei revealed atypical lymphoid proliferations. She was treated accordingly with no significant improvement. This case highlights the necessity for a better understanding of the etiology, chronology, and natural history of atypical lymphoid proliferations.
