Aortic dissection is a tear in the wall of the aorta that causes blood to flow between the layers of the wall of the aorta and force the layers apart.[1] Aortic dissection is a medical emergency and can quickly lead to death, even with optimal treatment. If the dissection tears the aorta completely open (through all three layers), massive and rapid blood loss occurs. Aortic dissections resulting in rupture have an 80% mortality rate, and 50% of patients die before they even reach the hospital. If the dissection reaches 6 cm, the patient must be taken for emergency surgery. Dr. Michael E. DeBakey, who devised the surgery to correct aortic dissection (as well as other cardiovascular and vascular techniques). Dr. DeBakey was also noteworthy for being the oldest patient ever to receive his own operation: he was 97 at the time of his surgery on February 9 and 10 of 2006. He survived and, though he worked with physical therapists to walk on his own again after suffering muscle deconditioning from prolonged physical inactivity during recovery, retained all of his mental faculties and was back to working nearly a full day until his death of natural causes on July 11, 2008. Famous victims of aortic dissections include Lucille Ball, actress and entertainer, and actor John Ritter. [READ THE REST OF THIS ARTICLE]
Cysticercosis, or neurocysticercosis, is the most common parasitic infestation of the central nervous system worldwide. Humans develop cysticercosis when they ingest eggs or larvae of the tapeworm Taenia solium. The eggs and larvae are usually found in fecally-contaminated water and undercooked pork. Humans can be infected by ingesting the eggs or larvae from eating undercooked pork that contains viable cysticercosis larvae or from fecally contaminated food or water. Upon reaching the small intestine, the scolex attaches to the intestinal wall and a proglottid chain grows. T.solium releases three to six proglottids/day, bearing 30,000 to 70,000 eggs (ova) per proglottid into the intestine. Nearly 250,000 ova are passed daily into the human feces and to the environment, and the cycle continues. Infections with cysticercus occur after humans consume the ova from exogenous sources or through self-infection via the fecal-oral route. Humans, in this case, are intermediate hosts. Ova are digested in the stomach and release oncospheres which penetrate the intestinal wall and reach the bloodstream. These oncospheres develop into cysticerci in any organ but are common in brain, subcutaneous tissue, or eyes. The adult tapeworm develops in humans after the ingestion of infected meat; however cysticercosis occurs after the ingestion of eggs, either from external sources or from their own feces. Pigs get infected with cysticerci when they ingest human feces. The incubation period ranges from months to over ten years. Treatment must be tailored to the specific needs of the patient and may include medical drugs such as antihelminthic drugs and corticosteroids or surgery. Surgical treatment includes direct excision of ventricular cysts, shunting procedures, and removal of cysts via endoscopy. [READ THE REST OF THIS ARTICLE]
Necrotizing fasciitis (NF), commonly known as flesh-eating disease or flesh-eating bacteria, is a rare infection of the deeper layers of skin and subcutaneous tissues, easily spreading across the fascial plane within the subcutaneous tissue. Type I describes a polymicrobial infection, whereas Type II describes a monomicrobial infection. The infection begins locally, at a site of trauma, which may be severe (such as the result of surgery), minor, or even non-apparent. Patients usually complain of intense pain that may seem in excess given the external appearance of the skin. With progression of the disease, tissue becomes swollen, often within hours. Diarrhea and vomiting are also common symptoms. In the early stages, signs of inflammation may not be apparent if the bacteria are deep within the tissue. If they are not deep, signs of inflammation such as redness and swollen or hot skin show very quickly. Skin color may progress to violet and blisters may form, with subsequent necrosis (death) of the subcutaneous tissues. Patients with necrotizing fasciitis typically have a fever and appear very ill. Mortality rates have been noted as high as 73 percent if left untreated. Without surgery and medical assistance, such as antibiotics, the infection will rapidly progress, and will eventually lead to death. [READ THE REST OF THIS ARTICLE]
Hemorrhoids, haemorrhoids, emerods, or piles are swelling and inflammation of veins in the rectum and anus. The anatomical term "hemorrhoids" technically refers to "'Cushions of tissue filled with blood vessels at the junction of the rectum and the anus." However, the term is popularly used to refer to varicosities of the hemorrhoid tissue. Perianal hematoma are sometimes misdiagnosed and mislabeled as hemorrhoids, when in fact they have different causes and treatments. Many anorectal problems, including fissures, fistulae, abscesses, anal melanoma or irritation and itching, also called pruritus ani, have similar symptoms and are incorrectly referred to as hemorrhoids. Hemorrhoids are usually not dangerous or life threatening. In most cases, hemorrhoidal symptoms will go away within a few days. Although many people have hemorrhoids,and hemorroidial radiation, not all experience symptoms. The most common symptom of internal hemorrhoidial radiation is bright red blood covering the feces (hematochezia), on toilet paper, and/or in the toilet bowl. However, an internal hemorrhoid may protrude through the anus outside the body, becoming irritated and painful. This is known as a protruding hemorrhoid. Symptoms of external hemorrhoids may include painful swelling or a hard lump around the anus that results when a blood clot forms. This condition is known as a thrombosed external hemorrhoid. In addition, excessive straining, rubbing, or cleaning around the anus may cause irritation with bleeding and/or itching, which may produce a vicious cycle of symptoms. Draining anal mucus, produced by the dentate line may also cause itching. [READ THE REST OF THIS ARTICLE]
In medicine, a lumbar puncture (colloquially known as a spinal tap) is a diagnostic and at times therapeutic procedure that is performed in order to collect a sample of cerebrospinal fluid (CSF) for biochemical, microbiological, and cytological analysis, or very rarely as a treatment ("therapeutic lumbar puncture") to relieve increased intracranial pressure. The most common purpose for a lumbar puncture is to collect cerebrospinal fluid in a case of suspected meningitis, since there is no other reliable tool with which meningitis, a life-threatening but highly treatable condition, can be excluded. Young infants commonly require lumbar puncture as a part of the routine workup for fever without a source, as they have a much higher risk of meningitis than older persons and do not reliably show signs of meningeal irritation (meningismus). In any age group, subarachnoid hemorrhage, hydrocephalus, benign intracranial hypertension and many other diagnoses may be supported or excluded with this test. Lumbar punctures may also be done to inject medications into the cerebrospinal fluid ("intrathecally"), particularly for spinal anesthesia or chemotherapy. Lumbar punctures can be unpleasant for some people, due to increased sensitivity when the needle is inserted to collect the cerebrospinal fluid. [READ THE REST OF THIS ARTICLE]
Meningitis is inflammation of the protective membranes covering the brain and spinal cord, known collectively as the meninges. The inflammation may be caused by infection with viruses, bacteria, or other microorganisms, and less commonly by certain drugs. Meningitis can be life-threatening because of the inflammation's proximity to the brain and spinal cord; therefore the condition is classified as a medical emergency. The most common symptoms of meningitis are headache and neck stiffness associated with fever, confusion or altered consciousness, vomiting, and an inability to tolerate light (photophobia) or loud noises (phonophobia). Sometimes, especially in small children, only nonspecific symptoms may be present, such as irritability and drowsiness. If a rash is present, it may indicate a particular cause of meningitis; for instance, meningitis caused by meningococcal bacteria may be accompanied by a characteristic rash. A lumbar puncture may be used to diagnose or exclude meningitis. This involves inserting a needle into the spinal canal to extract a sample of cerebrospinal fluid (CSF), the fluid that envelops the brain and spinal cord. The CSF is then examined in a medical laboratory. Meningitis can be diagnosed after death has occurred. The findings from a post mortem are usually a widespread inflammation of the pia mater and arachnoid layers of the meninges covering the brain and spinal cord. Neutrophil leucocytes tend to have migrated to the cerebrospinal fluid and the base of the brain, along with cranial nerves and the spinal cord, may be surrounded with pus—as may the meningeal vessels.

A pacemaker (or artificial pacemaker, so as not to be confused with the heart's natural pacemaker) is a medical device which uses electrical impulses, delivered by electrodes contacting the heart muscles, to regulate the beating of the heart. The primary purpose of a pacemaker is to maintain an adequate heart rate, either because the heart's native pacemaker is not fast enough, or there is a block in the heart's electrical conduction system. Modern pacemakers are externally programmable and allow the cardiologist to select the optimum pacing modes for individual patients. Some combine a pacemaker and defibrillator in a single implantable device. Others have multiple electrodes stimulating differing positions within the heart to improve synchronisation of the lower chambers of the heart. A pacemaker is typically inserted into the patient through a simple surgery using a local anesthetic. The patient is usually given a drug for relaxation, and an antibiotic to prevent infection. An incision is made in the left shoulder area below the collar bone where the pacemaker is actually housed in the patient's body. The lead or leads (the number of leads varies depending on the type of pacemaker) are fed into the heart through a large vein using a fluoroscope to monitor the progress of lead insertion. A temporary drain may be installed and removed the following day. The actual surgery may take about an hour. The patient should exercise reasonable care about the wound as it heals.
