Breast Cancer
Breast Cancer samer kareem 1,388 Views • 3 years ago

Breast cancer usually starts off in the inner lining of milk ducts or the lobules that supply them with milk. A malignant tumor can spread to other parts of the body. A breast cancer that started off in the lobules is known as lobular carcinoma, while one that developed from the ducts is called ductal carcinoma. The vast majority of breast cancer cases occur in females. This article focuses on breast cancer in women. We also have an article about male breast cancer. Breast cancer is the most common invasive cancer in females worldwide. It accounts for 16% of all female cancers and 22.9% of invasive cancers in women. 18.2% of all cancer deaths worldwide, including both males and females, are from breast cancer. Breast cancer rates are much higher in developed nations compared to developing ones. There are several reasons for this, with possibly life-expectancy being one of the key factors - breast cancer is more common in elderly women; women in the richest countries live much longer than those in the poorest nations. The different lifestyles and eating habits of females in rich and poor countries are also contributory factors, experts believe. According to the National Cancer Institute, 232,340 female breast cancers and 2,240 male breast cancers are reported in the USA each year, as well as about 39,620 deaths caused by the disease.

Retinoblastoma
Retinoblastoma samer kareem 1,388 Views • 3 years ago

Retinoblastoma is an eye cancer that begins in the retina — the sensitive lining on the inside of your eye. Retinoblastoma most commonly affects young children, but can rarely occur in adults. Your retina is made up of nerve tissue that senses light as it comes through the front of your eye. The retina sends signals through your optic nerve to your brain, where these signals are interpreted as images. A rare form of eye cancer, retinoblastoma is the most common form of cancer affecting the eye in children. Retinoblastoma may occur in one or both eyes.

Hypocalcemia
Hypocalcemia samer kareem 1,382 Views • 3 years ago

In neonates, hypocalcemia is more likely to occur in infants born of diabetic or preeclamptic mothers. Hypocalcemia also may occur in infants born to mothers with hyperparathyroidism. Clinically evident hypocalcemia generally presents in milder forms and is usually the result of a chronic disease state. In emergency department patients, chronic or subacute complaints secondary to mild or moderate hypocalcemia are more likely to be a chief complaint than severe symptomatic hypocalcemia. Once laboratory results demonstrate hypocalcemia, the first question is whether the hypocalcemia is true—that is, whether it is representative of a decrease in ionized calcium. The presence of chronic diarrhea or intestinal disease (eg, Crohn disease, sprue, chronic pancreatitis) suggests the possibility of hypocalcemia due to malabsorption of calcium and/or vitamin D. The patient's past medical history should be explored for pancreatitis, anxiety disorders, renal or liver failure, gastrointestinal disorders, and hyperthyroidism or hyperparathyroidism. Previous neck surgery suggests hypoparathyroidism; a history of seizures suggests hypocalcemia secondary to anticonvulsants. The patient may have a recent history of thyroid, parathyroid, or bowel surgeries or recent neck trauma. The length of time that a disorder is present is an important clue. Hypoparathyroidism and pseudohypoparathyroidism are lifelong disorders. Instead, acute transient hypocalcemia may be associated with acute gastrointestinal illness, nutritional deficiency, or acute or chronic renal failure. In an elderly patient, a nutritional deficiency may be associated with a low intake of vitamin D. A history of alcoholism can help diagnose hypocalcemia due to magnesium deficiency, malabsorption, or chronic pancreatitis. Inquire about recent use of drugs associated with hypocalcemia, including the following: Radiocontrast Estrogen Loop diuretics Bisphosphonates Calcium supplements Antibiotics Antiepileptic drugs Cinacalcet Other considerations in the history include the following: Family history of hypocalcemia Low-calcium diet Lack of sun exposure

Cervical Disc Surgical Technique
Cervical Disc Surgical Technique samer kareem 1,378 Views • 3 years ago

Patients are generally placed in a supine position with the head in an extended position. As noted above, Gardner-Wells tongs can be used for additional cervical traction. The hands can also be tied downward to increase the operative exposure. Once the surgical site is properly prepared with cleansing material, the appropriate surgical level is identified with intraoperative radiographs. A scalpel is used to make a linear longitudinal incision just medial to the body of the sternocleidomastoid muscle. The incision is made long enough to include at least 2 vertebral levels if a 1-level discectomy is being performed. Alternatively, transverse skin incisions over the targeted vertebral level can also be performed. The platysmal muscle is identified and incised. The platysmal incision can be extended if a multilevel decompression is the surgical aim. Extensive subplatysmal dissection is performed to reduce retraction injury.

A cervical herniated disc may be treated by removing part of the disc through a small incision (microdiscectomy). If this is done from the back (posteriorly) rather than from the front of the neck, a spinal fusion is not necessary. The alternative is an anterior cervical discectomy and fusion procedure.

An arthroscopic meniscectomy is a procedure to remove some or all of a meniscus from the tibio-femoral joint of the knee using arthroscopic (aka 'keyhole') surgery. In a complete meniscectomy the meniscus including the meniscal rim is removed. A partial meniscectomy involves partial removal of the meniscus. This may vary from minor trimming of a frayed edge to anything short of removing the rim. This is a minimally invasive procedure often done as day suas an outpatient in a one-day clinic [1] This procedure is performed when a meniscal tear is too large to be corrected by a surgical meniscal repair.[1] When non-operative therapy provides some degree of symptom relief over the long-term, these benefits may wane with continued meniscal degeneration. In such patients, arthroscopic partial meniscectomy can be effective in improving patient quality of life.
