Neurotransmission
Neurotransmission samer kareem 1,485 Views • 2 years ago

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.

Chinese man grows ear on arm in medical breakthrough
Chinese man grows ear on arm in medical breakthrough Scott 8,336 Views • 2 years ago

A plastic surgeon in China has successfully grown an artificial ear on a man's arm in a pioneering medical procedure. The patient, surnamed Ji, lost his right ear in an accident and yearned to have it back. Doctor Guo Shuzhong from a hospital in Xi'an, China's Shaanxi Province, used Mr Ji's cartilage from his ribs to build the new ear; and he expects to transplanted the organ to the man's head in about four months. According to the Huanqiu report, Mr Ji sustained serious injuries in the right side of his face in a traffic accident about a year ago. His right ear was torn from his face. The man, whose age is not specified, has since received multiple surgical operations to restore his facial skin and his cheeks. However, he felt frustrated about losing his right ear for good. The patient told a report from China News: 'I lost one ear. I have always felt that I am not complete.' Having sought medical advice from multiple sources, Ji realised that it was impossible to restore his ear through conventional medical procedures as a substantial part of his right ear had gone missing. Upon hearing recommendations, Mr Ji went to see doctor Guo Shuzhong, who works at the First Affiliated Hospital of Xi'an Jiaotong University in the city of Xi'an. Doctor Guo, a renowned plastic surgeon, conducted China's first face transplant operation in 2006, according to China Daily.

Neonatal Examination
Neonatal Examination samer kareem 19,183 Views • 2 years ago

A brief screening examination should be conducted checking the face, eyes, mouth, chest, abdomen, spine and limbs to exclude major abnormalities. A strong cry and a widespread pink blush over the face and body are good signs that all is well. Some children may be born with ambiguous genitalia. Ambiguous genitalia is a medical emergency and requires urgent assessment by a paediatrician. If you have sufficient clinical experience, an orogastric tube should be passed when the neonate's mother has suffered polyhydramnios. This excludes oesophageal atresia.

Treat HEMORRHOIDS
Treat HEMORRHOIDS samer kareem 2,913 Views • 2 years ago

Most of the time, treatment for hemorrhoids involves steps that you can take on your own, such as lifestyle modifications. But sometimes medications or surgical procedures are necessary. Medications If your hemorrhoids produce only mild discomfort, your doctor may suggest over-the-counter creams, ointments, suppositories or pads. These products contain ingredients, such as witch hazel or hydrocortisone, that can relieve pain and itching, at least temporarily. Don't use an over-the-counter cream or other product for more than a week unless directed by your doctor. These products can cause side effects, such as skin rash, inflammation and skin thinning. Minimally invasive procedures If a blood clot has formed within an external hemorrhoid, your doctor can remove the clot with a simple incision, which may provide prompt relief. For persistent bleeding or painful hemorrhoids, your doctor may recommend another minimally invasive procedure. These treatments can be done in your doctor's office or other outpatient setting. Rubber band ligation. Your doctor places one or two tiny rubber bands around the base of an internal hemorrhoid to cut off its circulation. The hemorrhoid withers and falls off within a week. This procedure — called rubber band ligation — is effective for many people. Hemorrhoid banding can be uncomfortable and may cause bleeding, which might begin two to four days after the procedure but is rarely severe. Injection (sclerotherapy). In this procedure, your doctor injects a chemical solution into the hemorrhoid tissue to shrink it. While the injection causes little or no pain, it may be less effective than rubber band ligation. Coagulation (infrared, laser or bipolar). Coagulation techniques use laser or infrared light or heat. They cause small, bleeding, internal hemorrhoids to harden and shrivel. While coagulation has few side effects, it's associated with a higher rate of hemorrhoids coming back (recurrence) than is the rubber band treatment. Surgical procedures If other procedures haven't been successful or you have large hemorrhoids, your doctor may recommend a surgical procedure. Surgery can be performed on an outpatient basis or you may need to stay in the hospital overnight. Hemorrhoid removal. During a hemorrhoidectomy, your surgeon removes excessive tissue that causes bleeding. Various techniques may be used. The surgery may be done with a local anesthetic combined with sedation, a spinal anesthetic or a general anesthetic. Hemorrhoidectomy is the most effective and complete way to treat severe or recurring hemorrhoids. Complications may include temporary difficulty emptying your bladder and urinary tract infections associated with this problem. Most people experience some pain after the procedure. Medications can relieve your pain. Soaking in a warm bath also may help. Hemorrhoid stapling. This procedure, called stapled hemorrhoidectomy or stapled hemorrhoidopexy, blocks blood flow to hemorrhoidal tissue. Stapling generally involves less pain than hemorrhoidectomy and allows an earlier return to regular activities. Compared with hemorrhoidectomy, however, stapling has been associated with a greater risk of recurrence and rectal prolapse, in which part of the rectum protrudes from the anus. Talk with your doctor about what might be the best option for you.

Getting to Know Children's: Renal Dialysis 30 Scott 156 Views • 2 years ago

In the Dialysis Unit you have an opportunity to provide Dialysis care for a variety of patients, including those with End-Stage Chronic Kidney disease and acutely ill patients requiring dialysis and plasmapheresis.
The Chronic Dialysis Nurse focuses on patients receiving Hemodialysis, Peritoneal Dialysis, or Home Hemodialysis. Our patients range in age from newborns to young adults. The Hemodialysis patient receives their dialysis treatment in the clinic 3-5 times a week. The Peritoneal Dialysis and Home Hemodialysis treatments are provided in the patient’s home once the parent/caregiver is trained to operate the machine. They are followed monthly in clinic. The patient receiving Chronic Dialysis is supported by a multidisciplinary team that consists of a physician, nurses, social worker, nutritionist, pharmacist, child-life therapist, teacher, and counselor. The group works together to meet the medical and emotional needs of the patient and caregiver. Care is specialized to meet the needs of each individual patient.
The Acute Dialysis Nurse focuses on acute dialysis related therapies such as: Continuous Renal Replacement Therapy (CRRT); therapeutic plasmapheresis; or acute peritoneal dialysis. The acute dialysis team works with the multi-disciplinary inpatient nephrology team to provide acute dialysis services to the critically ill ICU patients. The work environment is highly technical and fast-paced.
The Dialysis Unit operates on 12hr shifts 7a – 7p; 7 days a week. Night call is required and shared by the nurses. We provide a detailed orientation plan to the nurse to become proficient in providing hemodialysis, peritoneal dialysis, continuous renal replacement therapy and plasmapheresis. Previous experience in dialysis or pediatrics is not required.

Severe combined immunodeficiency
Severe combined immunodeficiency samer kareem 1,705 Views • 2 years ago

Severe combined immunodeficiency (SCID) is a life-threatening syndrome of recurrent infections, diarrhea, dermatitis, and failure to thrive. It is the prototype of the primary immunodeficiency diseases and is caused by numerous molecular defects that lead to severe compromise in the number and function of T cells, B cells, and occasionally natural killer (NK) cells. Clinically, most patients present before age 3 months. Without intervention, SCID usually results in severe infection and death in children by age 2 years. A committee of experts, initially sponsored by the World Health Organization (WHO), meets every 2 years with the goal to classify the group of primary immunodeficiency diseases according to current understanding of the pathways that become defective in the immune system.[1] Eight classification groups have been determined, with SCID being one of the best studied. Over the past few decades, the diverse molecular genetic causes of SCID have been identified with progress from studies of the immune system.[2] SCID is considered a pediatric emergency because survival depends on expeditious stem cell reconstitution, usually by bone marrow transplantation (BMT). Appropriate diagnosis is essential because instituting proper treatment is lifesaving. Despite the heterogeneity in the pathogenesis of immune defects, common cutaneous manifestations and typical infections can provide clinical clues in diagnosing this pediatric emergency.[3] Skin manifestations were prevalent in primary immunodeficiency disorders studied in 128 pediatric patients in Kuwait; skin infections were the most prevalent findings, seen in 39 patients (30%), followed by dermatitis in 24 (19%).[4] Skin infections were significantly more prevalent in those with congenital defects in phagocyte number, function, or both, as well as in those with well-defined immunodeficiencies. Dermatitis was evident in all patients with hyper–immunoglobulin (Ig) E syndrome and Wiskott-Aldrich syndrome.[4] Erythroderma of infancy with diffuse alopecia was seen exclusively in patients with SCID disorders, and telangiectasia in patients with ataxia telangiectasia; and partial albinism with silvery gray hair was associated with Chediak-Higashi syndrome. With the advances in BMT and gene therapy, patients now have a better likelihood of developing a functional immune system in a previously lethal genetic disease. However, once an infant develops serious infections, intervention is rarely successful.
