Intradural Arachnoid Cysts

Abstract Background Primary intradural spinal arachnoid cysts are rare pathologies of uncertain etiology and variable presentation from no symptoms to myelopathy or radiculopathy according to cord or root compression. MRI with diffusion and contrast differentiates them from many pathologies. There is a lot of debate regarding when to treat and how to treat such rare pathologies. Objective We present a series of 10 primary intradural arachnoid cysts and evaluate outcome after surgery. Methods This retrospective study includes patients having primary intradural spinal arachnoid cysts operated in two tertiary care centers from October 2012 till October 2019. Symptomatic cysts were subjected to microsurgical resection or outer wall excision and inner wall marsupialization under neurophysiological monitoring. The Japanese Orthopedic Association Score was used for clinical evaluation while MRI with contrast and diffusion was used for radiological evaluation before and after surgery. Results This series included 10 patients, 4 males and 6 females, with mean age of 40 years. Pain was the most common presentation. The most common location was dorsal thoracic region. Total excision was achieved in 2 cases and marsupialization in 8 cases. All symptoms improved either completely or partially after surgery. No neurological deterioration or recurrence was reported during the follow-up period in this series. Conclusion Treatment of symptomatic primary intradural spinal arachnoid cysts should be microsurgical resection, when the cyst is adherent to the cord, microscopic fenestration can be safe and effective.

Purpose: Ultrasound-facilitated, catheter-directed, low-dose fibrinolysis (USAT) appears to provide promising results for the management of acute submassive pulmonary embolisms (ASMPEs) at tertiary care centers. This study assessed outcome measures at a community-based hospital systems and compared results to known studies. Materials and Methods: This is a single-center, retrospective study assessing clinical outcomes of the EkoSonic Endovascular System intervention for ASMPEs performed by three surgical 3 subspecialties (interventional radiology, interventional cardiology, and vascular surgery) part of a pulmonary embolism response team (PERT). We reviewed 146 PERT activations from June 2013 to December 2017. Eighty-three patients with ASMPEs underwent USAT. Results: Our study showed greater differences ( P = .01) between baseline and follow-up pulmonary artery systolic pressures (20.9 ± 9.8 mm Hg [n = 14]) compared to the ULTIMA study (12.3 ± 10 mm Hg [n = 30]). Our length-of-stay measures were shorter (6.1 ± 5.1 [n = 83]; P = .0001) compared to the SEATTLE II study (8.8 ± 5.0 [n = 150]). Preprocedure transthoracic echocardiograms (TTEs) were performed for 54 (65%) of 83 patients. Postprocedure TTEs at 48 hours was performed for 52 (62%) of 83 patients. Use of TTEs before and after intervention did not change outcomes. Intracranial hemorrhage was not observed in our patient population. There was no difference in outcomes between the three subspecialties in our study. Conclusions: Use of USAT in a community-based hospital PERT has similar outcomes to tertiary care centers. Furthermore, similar outcomes were observed between the three subspecialties suggesting development of a comprehensive care team for management of ASMPEs.

Intradural Arachnoid Cysts

Object The microsurgical removal of obstructions to CSF flow is the treatment of choice in the surgical management of intradural arachnoid cysts. Cardiac-gated phase-contrast MR imaging is an effective tool for the primary diagnosis and localization of arachnoid cysts. Microsurgery, however, does not lend itself to assessments of further adhesions beyond the borders of the exposed area. The use of a thin endoscope allows surgeons to assess intraoperatively whether the exposure is wide enough. Methods Between 2006 and 2010, a single neurosurgeon performed 31 consecutive microsurgical procedures with endoscopic assistance in 28 patients with spinal arachnoid adhesions. A MurphyScope endoscope was used for this purpose. The CSF flow was studied before and after surgery in all patients by using phase-contrast MR imaging in the region of the craniocervical junction, the cervical spine, the thoracic spine, and the lumbar spine. Results In all 31 procedures, CSF flow obstructions were detected at the level identified by phase-contrast MR imaging. In 29 procedures, image quality was sufficient for an inspection of the adjacent subarachnoid space. In 6 cases, the surgeon detected further adhesions that obstructed CSF flow in the adjacent subarachnoid space that were not visualized with the microscope. In all cases, these adhesions were identified and removed during microsurgery. Conclusions Arachnoscopy is a helpful adjunct to microsurgery and can be performed safely and easily. It allows the surgeon to detect further adhesions in the subarachnoid space that would remain undetected by microscopy alone.

Abstract Context: Mutations in TAC3 and TACR3 (encoding neurokinin B and its receptor) have been identified in Turkish patients with idiopathic hypogonadotropic hypogonadism (IHH), but broader populations have not yet been tested and genotype-phenotype correlations have not been established. Objective: A broad cohort of normosmic IHH probands was screened for mutations in TAC3/TACR3 to evaluate the prevalence of such mutations and define the genotype/phenotype relationships. Design and Setting: The study consisted of sequencing of TAC3/TACR3, in vitro functional assays, and neuroendocrine phenotyping conducted in tertiary care centers worldwide. Patients or Other Participants: 345 probands, 18 family members, and 292 controls were studied. Intervention: Reproductive phenotypes throughout reproductive life and before and after therapy were examined. Main Outcome Measure: Rare sequence variants in TAC3/TACR3 were detected. Results: In TACR3, 19 probands harbored 13 distinct coding sequence rare nucleotide variants [three nonsense mutations, six nonsynonymous, four synonymous (one predicted to affect splicing)]. In TAC3, one homozygous single base pair deletion was identified, resulting in complete loss of the neurokinin B decapeptide. Phenotypic information was available on 16 males and seven females with coding sequence variants in TACR3/TAC3. Of the 16 males, 15 had microphallus; none of the females had spontaneous thelarche. Seven of the 16 males and five of the seven females were assessed after discontinuation of therapy; six of the seven males and four of the five females demonstrated evidence for reversibility of their hypogonadotropism. Conclusions: Mutations in the neurokinin B pathway are relatively common as causes of hypogonadism. Although the neurokinin B pathway appears essential during early sexual development, its importance in sustaining the integrity of the hypothalamic-pituitary-gonadal axis appears attenuated over time.

Background: Inhaled pulmonary vasodilators are used as adjunctive therapies for the treatment of refractory hypoxemia. Available evidence suggest they improve oxygenation in a subset of patients without changing long-term trajectory. Given the differences in respiratory failure due to COVID-19 and “traditional” ARDS, we sought to identify their physiologic impact. Methods: This is a retrospective observational study of patients mechanically ventilated for COVID-19, from the ICUs of 2 tertiary care centers, who received inhaled epoprostenol (iEpo) for the management of hypoxemia. The primary outcome is change in PaO2/FiO2. Additionally, we measured several patient level features to predict iEpo responsiveness (or lack thereof). Results: Eighty patients with laboratory confirmed SARS-CoV2 received iEpo while mechanically ventilated and had PaO2/FiO2 measured before and after. The median PaO2/FiO2 prior to receiving iEpo was 92 mmHg and interquartile range (74 – 122). The median change in PaO2/FiO2 was 9 mmHg (-9 – 37) corresponding to a 10% improvement (-8 – 41). Fifty-percent (40 / 80) met our a priori definition of a clinically significant improvement in PaO2/FiO2 (increase in 10% from the baseline value). Prone position and lower PaO2/FiO2 when iEpo was started predicted a more robust response, which held after multivariate adjustment. For proned individuals, improvement in PaO2/FiO2 was 14 mmHg (-6 to 45) vs. 3 mmHg (-11 – 20), p = 0.04 for supine individuals; for those with severe ARDS (PaO2/FiO2 < 100, n = 49) the median improvement was 16 mmHg (-2 – 46). Conclusion: Fifty percent of patients have a clinically significant improvement in PaO2/FiO2 after the initiation of iEpo. This suggests it is worth trying as a rescue therapy; although generally the benefit was modest with a wide variability. Those who were prone and had lower PaO2/FiO2 were more likely to respond.

Microsurgical Resection

Foramen magnum (FM) meningiomas are challenging lesions. We present the case of a 38-year-old female with neck pain, dysphonia, and slight twelfth nerve palsy. Imaging workup was highly suggestive of an FM meningioma, and microsurgical resection with the aid of intraoperative neurophysiological monitoring was indicated. A transcondylar approach was employed, the vertebral artery was mobilized, and the tumor was completely removed. Postoperative MRI demonstrated complete resection. There were no signs of cervical instability. The patient presented with improvement of her symptoms and no new neurological deficit on follow-up. FM meningiomas can be successfully resected using a transcondylar approach, since it increases the exposure of the ventral FM, allowing the surgeon to work parallel to the skull base and flush with the tumor’s attachment. Informed consent was obtained from the patient for publication of this operative video.The video can be found here: https://youtu.be/itfUOB-6zM0.

Abstract Background Telemedicine (TM) has emerged as a viable solution to extend infectious disease (ID) expertise to communities without access to this specialty.1 TM allows clinicians in rural settings to connect with specialists at distant sites and provide the best care for their patients, often eliminating the need for hospital transfers. Here, we describe the experience from one of the longest standing inpatient Tele-ID consult services using live audio-video (AV) visits with the assistance of a telepresenter. Methods Longitudinal data were collected from a 126-bed rural hospital in Pennsylvania that had no access to ID consultation before 2014. Live AV consults during business hours began in 2014 and telephonic physician to physician consults were made available 24/7. All ID consult data were extracted from the hospital electronic health record between 2014 to 2019. Key outcomes assessed included the number of consult encounters, total hospital length of stay (LOS), discharges to home, transfer to tertiary care centers, and readmission rates at 30 days. Results Most consulted patients were Caucasians, and females with an average age of 64.7 years (Table 1). The number of unique consult encounters increased annually from 111 in 2014 to 469 in 2019 (Table 1). The Charlson Comorbidity Score and Elixhauser Comorbidity Index also increased each year beginning in 2016 (Table 1). By contrast, LOS decreased each year as did the 30-day readmission rate (Table 2). Most patients were not transferred (average 89.4% over 6 years) to tertiary care centers and more than half were discharged to home each year (Table 2). Conclusion This longitudinal 6-year observation study of an inpatient TM ID service at a rural hospital showed remarkable annual growth in consult encounters (total growth &gt;400%). Despite increasing patient acuity, overall hospital LOS decreased over time (10.2 to 8.2 days). Patient transfers to tertiary care centers remained low (average 10.5% over 6 years) as did 30-day readmissions (average 16.3% over 6 years). The majority of patients were discharged to home (average 61.3% over 6 years). These findings show that a rural inpatient TM ID consult service can expand over time and is an effective alternative for hospitals without access to ID expertise.

Abstract Objectives Patients with epilepsy and their family have diverse beliefs about the cause of their illness that generally determine their treatment-seeking behavior. In this study, our aim was to find out different beliefs about epilepsy that lead to different help-seeking patterns, which act as barrier to the intended modern medical management of epilepsy. Materials and Methods One hundred and fifty consecutive consenting patients accompanied by a reliable informant/family member fulfilling the International Classification of Epileptic Seizures (ICES), simplified version, were included. Demographic and clinical data of all the eligible subjects was collected. Perceived cause of illness and help-seeking pattern were explored from patient/informant by administering proper instruments. Results Respondents identified varied causes of epilepsy and explored multiple help-seeking options before reaching tertiary care centers. We observed that, generally, epileptic patients/relatives who had belief in causes like supernatural causes sought help from nonprofessional personnel and those attributed their symptom to bodily pathology had professional help-seeking. Conclusions The belief in supernatural causes not being conformed to the biomedical models of the epileptic disorders increases the treatment gap.

Background: Patients approaching end of life may experience intractable symptoms managed with palliative sedation. The legalization of Medical Assistance in Dying (MAiD) in Canada in 2016 offers a new option for relief of intolerable suffering, and there is limited evidence examining how the use of palliative sedation has evolved with the introduction of MAiD. Objectives: To compare rates of palliative sedation at a tertiary care hospital before and after the legalization of MAiD. Methods: This study is a retrospective chart analysis of all deaths of patients followed by the palliative care consult team in acute care, or admitted to the palliative care unit. We compared the use of palliative sedation during 1-year periods before and after the legalization of MAiD, and screened charts for MAiD requests during the second time period. Results: 4.7% (n = 25) of patients who died in the palliative care unit pre-legalization of MAiD received palliative sedation compared to 14.6% (n = 82) post-MAiD, with no change in acute care. Post-MAiD, 4.1% of deaths were medically-assisted deaths in the palliative care unit (n = 23) and acute care (n = 14). For patients who requested MAiD but instead received palliative sedation, the primary reason was loss of decisional capacity to consent for MAiD. Conclusion: We believe that the mainstream presence of MAiD has resulted in an increased recognition of MAiD and palliative sedation as distinct entities, and rates of palliative sedation increased post-MAiD due to greater awareness about patient choice and increased comfort with end-of-life options.
