Objective:To describe an alternative antibiotic regimen for the treatment of central nervous system Listeria monocytogenes infection.Background:Classical treatment of listeria infections of the brain and spinal cord has included ampicillin in combination with gentamicin and chloramphenicol. Antibiotic resistance to L. monocytogenes is extraordinarily low, and the combined risks of nephrotoxicity, ototoxicity, and agranulocytosis in an already critically ill patient make the potential use of trimethoprim-sulfamethoxazole monotherapy for coverage or treatment of listeria an important alternative.Methods:Case report.Results:A 58-year-old woman presented with a two-week history of progressive quadriplegia. Gadolinium enhanced MRI showed diffuse edema of the cervical and thoracic spine with ring-enhancing lesions. Cerebrospinal fluid and blood cultures both grew L. monocytogenes. Spinal cord biopsy of the lesion revealed inflammation with necrosis and also grew listeria. Intravenous trimethoprim-sulfamethoxazole (8 mg/kg in four divided doses) was administered for six weeks with resultant arrest of neurological symptoms and stabilization of the clinical course. Although the patient was quadraparetic she was able to be discharged to a rehabilitation facility.Conclusions:Trimethoprim-sulfamethoxazole monotherapy may be a potential alternative option for critically ill patients with central nervous system L. monocytogenes infection.

Superficial Siderosis (SS) of Central Nervous System is a rare disease characterized by the deposit of hemosiderin in the brain and spinal cord. Clinically, it is characterized by progressive sensorineural ataxia and deafness associated with injury of superior motor neuron. The diagnosis is made by magnetic resonance imaging (MRI) of the encephalon and spinal cord. The objective of the study is to report the case of a patient with characteristic elements of the syndrome, accompanied in a private medical clinic.

Central Lesions

Rothmann points out how important it is to surgeons that the localisation of lesions in the brain and spinal cord should be made with the utmost accuracy. In many cases diseases do not strike suddenly upon a nervous system previously intact. Often the circulation has been previously deranged by arterial sclerosis, which prepares the way for transitory hemiplegia or aphasia. Sometimes there is loss of function after central lesions, which disappears in longer or shorter time. Goltz and his followers have treated many effects following the extirpation of the whole or part of the cerebrum as due to what they call inhibition (Hemmung). Thus the functions of the spinal cord are much impaired after removal of the cerebral ganglia, or the lower portion of the cord loses its reflex function after section higher up, but after a while it again resumes its act$ibon.

This chapter looks at electrophysiological studies of the central nervous system and peripheral nervous system—the core investigations in clinical neurophysiology. These include electroencephalography, which is of value to diagnose epilepsy caused by focal or diffuse brain diseases, electromyography and nerve conduction studies, which are of value to diagnose diseases in nerves and muscles, and evoked potentials, which are of value to diagnose diseases of white matter in the brain and spinal cord.

Abstract The genus Myxobolus, parasites that infect fishes, which cause myxobolosis, includes spore organisms belonging to the phylum Myxozoa and represents approximately 36% of all species described for the entire phylum. This study describes lymphocytic meningoencephalomyelitis associated with Myxobolus sp. infection in the brain and spinal cord (the central nervous system, CNS) of Eigenmannia sp., from the Amazon estuary region, in the Administrative District of Outeiro (DAOUT), Belém, Pará, Brazil. In May and June 2015, 40 Eigenmannia sp. specimens were captured from this region and examined. The fish were anesthetized, slaughtered and dissected for sexing (gonad evaluation) and studying parasites and cysts; after diagnosing the presence of the myxozoans using a light microscope, small fragments of the brain and spinal cord were removed for histological processing and Hematoxylin-Eosin and Ziehl-Neelsen staining. Histopathological analysis of the brain and spinal cord, based on histological sections stained with Hematoxylin-Eosin, pronounced and diffuse edema in these tissues, and congestion, degeneration, and focal necrosis of the cerebral cortex. The present study describes lymphocytic meningoencephalomyelitis associated with infection by Myxobolus sp. in the central nervous system of Eigenmannia sp.

Immune localization of heme oxygenase-2 in neurons of some nuclei of the spinal cord and brain stem in 6 men 18–44 years old who died from causes unrelated to injury of central nervous system was studied. Neurons with positive reaction are determined for all studied regions of the brain where their contents in various nuclei ranging from 0,5 to 16% of the total number of cells detected by methylene blue. In all the sensory nuclei there is a high proportion of small neurons with a high or moderate density of reaction produc deposits. Large cells of motor nuclei often exhibit negative or low intensive enzyme reaction.

Benefit And Risk

Background: Brain is the most sensitive organ, whereas brainstem is the most important part of Central Nervous System (CNS). It connects the brain and the spinal cord. However, a myriad of drugs and chemicals affects CNS with severe resultant effects on the brainstem. Methods: In view of this, a number of literature were assessed for information on the most sensitive part of brain, drugs and chemicals that act on the brainstem and clinical benefit and risk assessment of such drugs and chemicals. Results: Findings have shown that brainstem regulates heartbeat, respiration and because it connects the brain and spinal cord, all the drugs that act on the spinal cord may overall affect the systems controlled by the spinal cord and brain. The message is sent and received by temporal lobe, occipital lobe, frontal lobe, parietal lobe and cerebellum. Conclusion: Hence, the chemical functional groups of the brainstem and drugs acting on brainstem are complementary, and may produce either stimulation or depression of CNS.

A wide variety of nematode species have been observed to invade the central nervous system. They may be located in the meningeal spaces or may penetrate into the tissues of the brain and spinal cord.The pathological changes resulting from invasion of the central nervous system are influenced by the route of entry, the size and the mobility of the parasite. They may be diffuse or focal and may include haemorrhage, degenerative changes, cellular infiltration and glial proliferation. Such changes may or may not be observed in close association with the parasite.Symptoms indicating involvement of the central nervous system have long been associated with nematode infections outside the central nervous system. The pathogenesis of these symptoms is obscure, but they may possibly be of allergic origin.The direct pathological effects on the central nervous system are mainly the result of trauma and are directly proportional to the size and activity of the parasite. The possibility that nematodes may transport viruses into the central nervous system is briefly discussed.
