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.
Video shows the procedure of videoendoscpy and endoscopic removal of polyps.

Osgood Schlatter disease
Osgood Schlatter disease samer kareem 3,817 Views • 2 years ago

Osgood-Schlatter disease can cause a painful lump below the kneecap in children and adolescents experiencing growth spurts during puberty. Osgood-Schlatter disease occurs most often in children who participate in sports that involve running, jumping and swift changes of direction — such as soccer, basketball, figure skating and ballet. While Osgood-Schlatter disease is more common in boys, the gender gap is narrowing as more girls become involved with sports. Age ranges differ by sex because girls experience puberty earlier than do boys. Osgood-Schlatter disease typically occurs in boys ages 13 to 14 and girls ages 11 to 12. The condition usually resolves on its own, once the child's bones stop growing.

Wilson Disease
Wilson Disease samer kareem 10,107 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.

Hypothalamus and Pituitary
Hypothalamus and Pituitary samer kareem 4,510 Views • 2 years ago

The pituitary gland is often portrayed as the "master gland" of the body. Such praise is justified in the sense that the anterior and posterior pituitary secrete a battery of hormones that collectively influence all cells and affect virtually all physiologic processes. The pituitary gland may be king, but the power behind the throne is clearly the hypothalamus. As alluded to in the last section, some of the neurons within the hypothalamus - neurosecretory neurons - secrete hormones that strictly control secretion of hormones from the anterior pituitary. The hypothalamic hormones are referred to as releasing hormones and inhibiting hormones, reflecting their influence on anterior pituitary hormones.

Adrenoleukodystrophy explained.
Adrenoleukodystrophy explained. samer kareem 4,268 Views • 2 years ago

X-linked adrenoleukodystrophy is a genetic disorder that occurs primarily in males. It mainly affects the nervous system and the adrenal glands, which are small glands located on top of each kidney. In this disorder, the fatty covering (myelin) that insulates nerves in the brain and spinal cord is prone to deterioration (demyelination), which reduces the ability of the nerves to relay information to the brain. In addition, damage to the outer layer of the adrenal glands (adrenal cortex) causes a shortage of certain hormones (adrenocortical insufficiency). Adrenocortical insufficiency may cause weakness, weight loss, skin changes, vomiting, and coma.

Basics of Multiple Endocrine Neoplasia
Basics of Multiple Endocrine Neoplasia samer kareem 5,097 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.
