Ca2+ binds with the membrane of the synaptic vesicles, which causes the vesicles to break and release the neurotransmitter into the synaptic cleft. After the neurotransmitters are released, they diffuse across the synaptic cleft and interact with receptors on the postsynaptic membrane. When the action potential reaches the presynaptic terminal, it provokes the release of a small quantity of neurotransmitter molecules, which bind to chemical receptor molecules located in the membrane of another neuron, the postsynaptic neuron, on the opposite side of the synaptic cleft.

Knee replacement, also called arthroplasty, is a surgical procedure to resurface a knee damaged by arthritis. Metal and plastic parts are used to cap the ends of the bones that form the knee joint, along with the kneecap. This surgery may be considered for someone who has severe arthritis or a severe knee injury.

Methotrexate anti-tumor activity is a result of the inhibition of folic acid reductase, leading to inhibition of DNA synthesis and inhibition of cellular replication. The mechanism involved in its activity against rheumatoid arthritis is not known.

6 987 24 MORE How Does Anesthesia Work? Credit: itsmejust | Shutterstock If you’ve ever had surgery, unless you are super tough, you’ve gone through it with the benefit of anesthetics. But, how do these body-numbing elixirs work? Prior to the invention of anesthesia in the mid-1800s, surgeons had to hack off limbs, sew up wounds and remove mysterious growths with nothing to dull the patient's pain but opium or booze. While these drugs may have numbed the patient, they didn’t always completely block the pain, or erase the memory of it. Since then, doctors have gotten much better at putting us out with drug combinations that ease pain, relax muscles and, in some cases, put us in a deep state of hypnosis that gives us temporary amnesia. Today, there are two primary types of anesthesia drugs: those that knockout the whole body (general) and those that only numb things up locally.

A step wise approach to the pathogenesis, types, disease entities and diagnosis of vasculitis. This discussion also includes the management options of vasculitis and their adverse drug reactions. In essence, vasculitis is a clfinicopathologic process characterised by inflammation and damage of blood vessels. This may be mainly due to three pathological processes which include immune complex deposition, anti-neutrophillic antibody formation and pathological T lymphocyte response and granuloma formation. The disease entities include Wegner's granulomatosis, Churg Strauss and many others. These present with palpable purpura, unexplained renal dysfunction etc which can be diagnosed based on biopsy and angiogram.

ENDOSCOPIC (NON-SURGICAL) REMOVAL OF MULTIPLE LARGE TUMORS FROM STOMACH IN A PATIENT WITH PEUTZ-JEGHERS SYNDROME
PEUTZ-JEGHERS SYNDROME: Peutz-Jeghers syndrome (PJS) is a familial syndrome consisting of mucocutaneous pigmentation, gastrointestinal polyposis and cancers of gut & other sites like breast, ovary, and testes. PJS has an autosomal dominant inheritance with variable and incomplete penetrance. Germline mutations of STK11/LKB1 gene on 19p cause this syndrome. Mucocutaneous pigmentation may be noted in early infancy. These deposits of melanin are most commonly found around the mouth, nose, lips, buccal mucosa, hands, and feet, and may also be present in perianal and genital areas. PJS polyps may be found in stomach, small intestine, or colon, but they tend to be prominent in the small intestine. These polyps may increase in size and cause small intestinal obstruction or intussusceptions that may occur in early infancy. Acute upper gastrointestinal bleeding and chronic faecal blood may complicate the disease.
PATIENT: The patient was a 25 yr male who had mucocutaneous pigmentation and multiple polyps in the stomach and duodenum. He presented with bleeding from gastric polyps. As the polyps in stomach were numerous, (more than 20 in number) and were large in size (some equal to small egg size), he had been advised to undergo surgery. Surgery planned was total gastrectomy.
PROCEDURE: The patient underwent video-endoscopy of the esophagus, stomach and duodenum. All polyps were examined for size and presence or absence of stalk. A plan to remove all the gastric polyps at endoscopy was made in the same sitting. He received light conscious sedation. Flat polyps were raised form the gastric wall by injection of saline in to polyp base to let these lesions have a stalk. This was done by needle injector. Each polyp was engaged in a snare and the polyp stalk was cut by coagulation cutting current. The cuts were clean without any bleeding. All polyps were recovered for histology. The histology revealed all polyps to be hamartomous lesions. None of the polyps were cancerous. Patient has been followed up for over one year and is doing fine without any further bleeding or pain.

Antisocial personality disorder (ASPD) is defined by the American Psychiatric Association's Axis II (personality disorders) of the Diagnostic and Statistical Manual (DSM-IV-TR) as "a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood." Antisocial personality disorder is sometimes wrongly referred to as psychopathy or sociopathy. Currently, neither psychopathy nor sociopathy are valid diagnoses described in the Diagnostic and Statistical Manual of Mental Disorders, and the ICD-10 of the World Health Organization also lacks psychopathy as a diagnostic disorder. Psychopathy is normally seen as a subset of the antisocial personality disorder, but Blair believes that the antisocial personality disorder and psychopathy may be separate conditions altogether.
