Biomimetic unnatural tissue to be able to style the result of membrane asymmetry on chemoresistance.
pharyngiomas and Rathke cleft cysts. Awareness of these errors should lead to improved management of sellar lesions.
The most common etiology of an isolated abducens nerve palsy in an older adult with vasculopathic risk factors is presumed microvascular ischemia. Because the diagnosis of microvascular ischemia in this setting would not alter patient management, there is debate as to whether further workup is warranted under these circumstances. In this report, we describe a fascicular sixth nerve palsy as the initial presenting sign of metastatic ovarian carcinoma, and we highlight the importance of considering additional workup in select cases of isolated abducens nerve palsies.

A 9-year-old girl presented with morning headaches associated with vomiting, gait ataxia, and facial and ocular motor nerve palsies. Her initial imaging was concerning for demyelinating disease. After extensive infectious and rheumatologic workup returned negative, she was treated twice with intravenous immunoglobulin and intravenous steroids with near-complete resolution each time. She returned, however, with worsening neurologic deficits and imaging revealing focal ischemic infarction in the brainstem as well as new-onset hydrocephalus. A multispecialty workup was initiated without conclusive diagnosis. A novel, noninvasive test for plasma cell-free DNA established a diagnosis of Cladophialophora bantiana that was confirmed and validated by a brain biopsy taken during a clinical decompensation. Treatment was initiated with systemic voriconazole and intraventricular amphotericin B.

Concomitant chorioretinal folds with disc edema can be seen in cases of thyroid eye disease presenting with compressive optic neuropathy and may portend optic nerve ischemia. We describe an unusual case of a 64-year-old man who developed partial vision loss after orbital decompression.

A 45-year-old man with a history of testicular seminoma treated 8 years earlier presented with chronic progressive truncal and limb ataxia, progressive sensorineural hearing loss, and episodic vertigo. Eye movement and neuro-otology examinations showed localizing abnormalities to the bilateral cerebellar flocculus, vermis, and bilateral cerebellar hemispheres. Audiometric testing showed bilateral symmetric sensorineural hearing loss. There was a normal MRI of the brain. Cerebrospinal fluid (CSF) showed modest lymphocytic pleocytosis, and there was an elevated serum choriogonadotrophic hormone. An abdominal CT scan showed a solitary, large retroperitoneal lymph node, and histopathologic examination of the node biopsy showed granulomatous inflammation without microorganisms; eventually, immunohistochemical markers confirmed the diagnosis of metastatic seminoma. Although normal neuroimaging and inflammatory CSF reaction suggested a paraneoplastic etiology, the initial paraneoplastic antibody testing was negatical markers confirmed the diagnosis of metastatic seminoma. Although normal neuroimaging and inflammatory CSF reaction suggested a paraneoplastic etiology, the initial paraneoplastic antibody testing was negative. Subsequent investigation identified a positive kelch-11 protein antibody, thus confirming the paraneoplastic connection between the metastatic seminoma and the subacute neurologic-cochleovestibular syndrome.
Healthcare is rapidly evolving toward value-focused objectives, integrating outcomes and cost instead of simply volume. Concepts pertaining to Enhanced Recovery After Surgery (ERAS), Lean, and claims-based risk-adjusted databases can be used to optimize value, but the application of Lean principles and risk-adjusted outcomes is poorly described in perioperative medicine in perioperative medicine.

Lean management and process optimization tools allow the consistent application of a perioperative medical framework of ERAS to improve outcomes. Vizient risk-stratified outcomes are often used by hospitals to measure and compare quality.

Understanding administrative databases and Lean concepts for change management will allow the perioperative physician to better align medical concepts with health system tools for improving quality and reducing cost.
