Infectious diseases in the central nervous system (CNS Infection: Neurosurgical aspect). Suppakit., d.SC., m.d., reserved good.Infectious diseases in the central nervous system is the most common problem is an emergency system and prasatnok from drug therapy, then in neurosurgical treatment before patients are caused by disability or death.The germs that cause diseases, viruses, bacteria (Bacteria) include (Virus), Mara (Parasite), fungi (Fungus), tuberculosis (Tuberculosis) and infection, which is found only in the central nervous system is private (Prion) protein substance which is causing the disease. The infection enters the nervous system occur in many ways, both directly (from trauma, surgery), infection from neighboring organs (such as nasal sinusitis), via the bloodstream, and some types of HIV that is not how it is. Mad dogs (Rabies) toxic fuel through the nerve end (Peripheral nerve), and Naegleria infection Herpes through cranial nerve (Olfactory bulb) 1 pair. Cause infection at different positions are bone (skull, spine: Ostromyelitis), the lining of the brain and spinal cord (Meningitis), channel lining North view (Epidural empyema), South (Subdural empyema) view the lining, beef brain (brain: Encephalitis, a brain infection, virus, bacteria, infection, Cerebritis: Brain abscess: abscess in the brain), spinal cord (Myelitis), ventricular (Ventriculitis)The current pattern of infection in the central nervous system changes quickly, both in terms of epidemics, drug resistance and treatment because. 1. spread fast and difficult to control because of the ease of travel from one place to another.2. to increase the number of patients with immune disease caused by HIV/AIDS, drug use, press change in patients with immune organs taken, treat cancer patient longevity, elderly, alcoholic beverage.3. drug-resistant germs of various adaptation more due to luxuries, antibiotic use than necessary.4. Advancement of science genetics side. Polymerase chain reaction technology (PCR) to detect the infection disease.Basic knowledge (Basic knownledge). Brain and spinal cord are important organs contained within the skull and spine when the channels of infection differs from other systems is additionally the result of inflammation caused by the infection, the effect caused by. 1. konkhrop in the channel area, possessing a skull, spine (Mass lesion) and/or pressure in the skull (Increased intracranial pressure), or add spine channel. The result of the brain (Brain herniation) pressed a brain stem, spinal cord (Spinal cord compression).2. disorders of water circulation, brain and spinal cord crisis casting water Chambers in the brain cavity.3. (Prion) diseases on forests, which found specific infections of the central nervous system only. Show clinical symptoms. Operation complications and diseases, so there are differences depending on the type of disease, infection, self-protection mechanisms are described later. Self defense mechanism (Host Defense).In the central nervous system has a self defense mechanism, anatomical (Anatomical Barrier) and the immune system (Immunological Response) by anatomical mechanisms primarily because of a lack of immune system.1. anatomical mechanisms (Anatomical Barrier). Brain and spinal cord protected doyowaiwa is infected skin, skull, brain and spinal cord membranes, Blood Brain Barrier, Blood system, CSF Barrier. Such hakowaiwa is destroyed, such as from injuries. The germs get into the nervous system easily.^ "In the lining of the brain and spinal cord in different skulls with skulls will view the section in the spinal cord is not firmly mounted to the view with the bone. Therefore, infection in the skull above the channel view (Epidura) will not only be broad distribution in the South channel view (Subdura) The section in the spinal cord infection in the North channel to view under view are broadcast to multiple levels of the spinal cord.Blood Brain Barrier system, Blood, CSF Barrier is an important system which is a special feature of the brain blood vessels that is different from the blood vessels in other organs, is screening the things will pass into the brain and spinal cord or brain cast. In order to prevent toxins and germs are not, brain and spinal cord pass through easily, but there is a disadvantage in certain types of antibiotic treatment is not able to pass through into the central nervous system as well. Therefore, to maintain the nervous system infection, so antibiotics must consider whether it can pass into the brain and spinal cord. In conjunction with the sensitivity of the fuel per pill.2. the immune system mechanisms (Immunological Response) contains a cellular response, Humoral response, Phagocytic Complement. In the central nervous system is the principle component phli lip klobu antibody segment very low, no white blood cells with Microglial cell, but seeing that lack immune system, nervous system infections occur and harm than other systems if the anatomical mechanism is damaged.Mechanisms of the nervous system infection and complications When a pathogen enters the nervous system, then the distribution. It causes symptoms of the infection and complications, depending on the.1. the types of germs. Some types of germs like disease such as tuberculosis of the brain in some locations like the Herpes virus is at the base of the brain, brain-like Temporal parts or Orbitofrontal Simplex, the virus poliomyelitis. Anterior Horn Cell parts like spinal cord, etc.2. the various types of complications occur, depending on the pathogen and disease duration.2.1 vulnerable water Chambers in the brain (Hydrocephalus), Burrows are often found in the brain, tuberculosis, worms in the brain (Cysticercosis) pig contact, meningitis, chronic (Chronic Meningitis).2.2 pressure of deflation in the skull (Increased Intracranial Pressure) increases found in almost any type of infection (with the exception of Prion) caused by inflammation, swelling or a brain, then there is an abscess in the brain lobes.2.3 cavity encephalitis (Ventriculitis) frequently found in bacterial meningitis, brain abscess in children.
