Acrodysostosis is a rare syndrome characterized by peripheral dysostosis, nasal hypoplasia, and frequently mental retardation. Only two adult cases of acrodysostosis have been reported to have neurological symptoms. ⋯ Special attention should be given to these patients to detect signs of spinal stenosis, as early decompression can lead to neurological recovery.

The Rho pathway has been shown to have a role in the pathophysiology of spinal cord injury (SCI). Upregulation of the Rho signaling pathway occurs as a result of SCI. Activation of Rho and its downstream effector kinases triggers growth cone collapse and represents a significant barrier to axon regeneration. Furthermore, there is evidence that Rho-ROCK signaling mediates the inhibitory effects of chondroitin sulfate proteoglycans on neurons, and that inhibition of Rho and ROCK can reverse chondroitin sulfate proteoglycan-mediated inhibition of neurite outgrowth. Work building on these findings suggests that inhibition of this pathway may boost neuroprotection and axonal regeneration after SCI. ⋯ The Rho pathway has been shown to have a role in the pathophysiology of SCI and preclinical and clinical work and is currently a promising target for the treatment of patients with SCI.

This study sought to characterize the utility of coregistered 11C-methionine positron emission tomography (MET-PET) with 3-T magnetic resonance imaging (3T MRI) in the diagnosis and follow-up of pituitary adenomas in patients with acromegaly and to compare MET-PET and 18F-fluorodeoxyglucose emission tomography (FDG-PET) for the evaluation of active or recurrent disease. ⋯ MET-PET is a sensitive technique for diagnosing persistent acromegaly, and its coregistration with 3T MRI has demonstrated a better definition of the interface, extension, and location of the lesion in the management of active postoperative acromegaly.

Telemedicine has always been used as a teleconsultation tool in neurological emergencies (e.g., triage in head injuries, stroke, and cerebrovascular accidents). At Sri Sathya Sai Institute of Higher Medical Sciences, Bangalore, India, we have been operating two teleconsultation sessions per week for the postoperative patient population, addressing routine follow-up and semiemergent conditions in this cohort of patients. At our center more than 80% of the neurosurgical procedures are conducted in patients traveling more than 1500 km. ⋯ There are very few reports of telemedicine use in routine outpatient teleconsultations in the available neurosurgical literature; those that are present do not differentiate or analyze the use in routine versus emergency neurosurgery. We discuss the role of this underused resource in the developing countries and retrospectively analyze the clinical data in more than 1500 patients and 3000 teleconsultations during a period of 6 years. We address the financial implications, psychosocial factors, and several other factors that could make this relatively modest technology an indispensible tool in current neurosurgical practice, especially in a developing country like India.

To identify deficiencies leading to readmissions to the University of Florida Neurosurgery Service by using the Institute for Healthcare Improvement STate Action on Avoidable Rehospitalizations Readmissions diagnostic tool and to report the opinions of patients, their families, and health care providers. ⋯ Systematic patterns and common themes associated with patient readmissions were identified for a neurosurgical service. These findings are now being used to implement changes in discharge planning.
