Basics of Multiple Endocrine Neoplasia
Basics of Multiple Endocrine Neoplasia samer kareem 5,094 Views • 2 years ago

Multiple endocrine neoplasia is a group of disorders that affect the body's network of hormone-producing glands (the endocrine system). Hormones are chemical messengers that travel through the bloodstream and regulate the function of cells and tissues throughout the body. Multiple endocrine neoplasia typically involves tumors (neoplasia) in at least two endocrine glands; tumors can also develop in other organs and tissues. These growths can be noncancerous (benign) or cancerous (malignant). If the tumors become cancerous, the condition can be life-threatening.

Cortisol and Glucocorticoids
Cortisol and Glucocorticoids samer kareem 3,644 Views • 2 years ago

The vast majority of glucocorticoid activity in most mammals is from cortisol, also known as hydrocortisone. Corticosterone, the major glucocorticoid in rodents, is another glucocorticoid. Cortisol binds to the glucocorticoid receptor in the cytoplasm and the hormone-receptor complex is then translocated into the nucleus, where it binds to its DNA response element and modulates transcription from a battery of genes, leading to changes in the cell's phenotype. Only about 10% of circulating cortisol is free. The remaining majority circulates bound to plasma proteins, particularly corticosteroid-binding globulin (transcortin). This protein binding likely decreases the metabolic clearance rate of glucocorticoids and, because the bound steroid is not biologically active, tends to act as a buffer and blunt wild fluctuations in cortisol concentration.

Spinal Injury - Jaw Thrust
Spinal Injury - Jaw Thrust samer kareem 5,630 Views • 2 years ago

The jaw thrust is a method of opening the airway of a patient. The airway is very important in first aid! It consists of the structures in the back of the throat and upper neck. A patient who is unconscious is not able to maintain their own airway as it can become blocked by the tongue (see picture). Normally, first aid courses teach the head tilt – chin lift technique to open an airway. However, this airway manoeuvre involves significant movement of the patient’s neck. Therefore if there is any suspicion of a spinal (neck) injury it may cause further damage.

Norepinephrine is synthesized from dopamine by dopamine β-hydroxylase.[7] It is released from the adrenal medulla into the blood as a hormone, and is also a neurotransmitter in the central nervous system and sympathetic nervous system where it is released from noradrenergic neurons.

Biliary Metal Stent Placement
Biliary Metal Stent Placement samer kareem 3,741 Views • 2 years ago

The placement of a percutaneous expandable biliary endoprosthesis was first reported in 1985 by Carrasco et al. in a canine model,[1] and the endoscopic placement of expandable metal stents to relieve biliary strictures in patients was first described in 1989.[2,3] Over the past two decades, the endoscopic approach to biliary endoprosthesis placement has largely supplanted the percutaneous approach. Self-expanding metal stents (SEMS) have traditionally been used for palliation of obstructive jaundice in patients with unresectable pancreaticobiliary tumors. However, SEMS are increasingly being used in patients with resectable cancers[4] and benign biliary strictures.[5] Uncovered SEMS (uSEMS) have been shown to have longer patency periods than plastic stents when used for malignant biliary obstruction and to be cost effective if the patient's life expectancy is greater than 4–6 months.[6–8] The common causes of malignant biliary obstruction are pancreatic cancer and cholangiocarcinoma.[9–11] Biliary drainage prior to surgical resection is controversial; several investigators have reported it to be beneficial owing to the improved tissue healing with reduced bilirubin levels,[12,13] but others have also reported its deleterious effects secondary to the additional intervention..

Wilson Disease
Wilson Disease samer kareem 10,103 Views • 2 years ago

Wilson's disease is a rare inherited disorder that causes too much copper to accumulate in your liver, brain and other vital organs. Symptoms typically begin between the ages of 12 and 23. Copper plays a key role in the development of healthy nerves, bones, collagen and the skin pigment melanin. Normally, copper is absorbed from your food, and any excess is excreted through bile — a substance produced in your liver.

Familial Hypocalciuric Hypercalcemia
Familial Hypocalciuric Hypercalcemia samer kareem 4,345 Views • 2 years ago

There are 3 genetic types of FHH based on chromosome location. FHH type 1 accounts for 65% of cases and is due to inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR). Loss of CaSR function results in a reduction in the sensitivity of parathyroid and renal cells to calcium levels so hypercalcemia is perceived as normal. The other 35% have either a mutation GNA11 (19p13.3) seen in FHH type 2 or AP2S1 (19q13.2-q13.3) seen in FHH type 3 (see these terms) or in genes not yet discovered. FHH is rarely caused by auto-antibodies against CaSR in those without a mutation.
