Dermatomyositis
Dermatomyositis samer kareem 1,555 Views • 2 years ago

Dermatomyositis (dur-muh-toe-my-uh-SY-tis) is an uncommon inflammatory disease marked by muscle weakness and a distinctive skin rash. Dermatomyositis affects adults and children alike. In adults, dermatomyositis usually occurs from the late 40s to early 60s. In children, the disease most often appears between 5 and 15 years of age. Dermatomyositis affects more females than males. There's no cure for dermatomyositis, but periods of remission — when symptoms improve spontaneously — may occur. Treatment can clear the skin rash and help you regain muscle strength and function.

Vaginoplasty
Vaginoplasty samer kareem 24,151 Views • 2 years ago

A vaginoplasty is a surgical procedure that tightens the vagina. This is done by removing excess vaginal lining and tightening the surrounding soft tissues and muscles. During delivery of a baby the vagina and surrounding tissues and muscles become stretched. After delivery the vagina may return to a more “normal” size, but it often fails to return to its’ pre pregnancy diameter. Generally, the more vaginal deliveries, the worse the condition gets. Many women will complain of decreased sensation and sexual satisfaction during intercourse. Commonly this is due to a lack of friction. Often their partner may notice a change although he may say nothing. Kegel exercises are often recommended but rarely succeed in restoring vaginal tightness.

Laparoscopy (from Ancient Greek λαπάρα (lapára) 'flank, side', and σκοπέω (skopéō) 'to see') is an operation performed in the abdomen or pelvis using small incisions (usually 0.5–1.5 cm) with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.[1]

Laparoscopic surgery, also called minimally invasive procedure, bandaid surgery, or keyhole surgery, is a modern surgical technique. There are a number of advantages to the patient with laparoscopic surgery versus an exploratory laparotomy. These include reduced pain due to smaller incisions, reduced hemorrhaging, and shorter recovery time. The key element is the use of a laparoscope, a long fiber optic cable system that allows viewing of the affected area by snaking the cable from a more distant, but more easily accessible location.

Laparoscopic surgery includes operations within the abdominal or pelvic cavities, whereas keyhole surgery performed on the thoracic or chest cavity is called thoracoscopic surgery. Specific surgical instruments used in laparoscopic surgery include obstetrical forceps, scissors, probes, dissectors, hooks, and retractors. Laparoscopic and thoracoscopic surgery belong to the broader field of endoscopy. The first laparoscopic procedure was performed by German surgeon Georg Kelling in 1901. There are two types of laparoscope:[2]

A telescopic rod lens system, usually connected to a video camera (single-chip or three-chip)
A digital laparoscope where a miniature digital video camera is placed at the end of the laparoscope, eliminating the rod lens system

The mechanism mentioned in the second type is mainly used to improve the image quality of flexible endoscopes, replacing conventional fiberscopes. Nevertheless, laparoscopes are rigid endoscopes. Rigidity is required in clinical practice. The rod-lens-based laparoscopes dominate overwhelmingly in practice, due to their fine optical resolution (50 µm typically, dependent on the aperture size used in the objective lens), and the image quality can be better than that of the digital camera if necessary. The second type of laparoscope is very rare in the laparoscope market and in hospitals.[citation needed]

Also attached is a fiber optic cable system connected to a "cold" light source (halogen or xenon) to illuminate the operative field, which is inserted through a 5 mm or 10 mm cannula or trocar. The abdomen is usually insufflated with carbon dioxide gas. This elevates the abdominal wall above the internal organs to create a working and viewing space. CO2 is used because it is common to the human body and can be absorbed by tissue and removed by the respiratory system. It is also non-flammable, which is important because electrosurgical devices are commonly used in laparoscopic procedures.[3]

Patient position

During the laparoscopic procedure, the position of the patient is either in Trendelenburg position or in reverse Trendelenburg. These positions have an effect on cardiopulmonary function. In Trendelenburg's position, there is an increased preload due to an increase in the venous return from lower extremities. This position results in cephalic shifting of the viscera, which accentuates the pressure on the diaphragm. In the case of reverse Trendelenburg position, pulmonary function tends to improve as there is a caudal shifting of viscera, which improves tidal volume by a decrease in the pressure on the diaphragm. This position also decreases the preload on the heart and causes a decrease in the venous return leading to hypotension. The pooling of blood in the lower extremities increases the stasis and predisposes the patient to develop deep vein thrombosis (DVT).[4]
Gallbladder

Rather than a minimum 20 cm incision as in traditional (open) cholecystectomy, four incisions of 0.5–1.0 cm, or more recently, a single incision of 1.5–2.0 cm,[5] will be sufficient to perform a laparoscopic removal of a gallbladder. Since the gallbladder is similar to a small balloon that stores and releases bile, it can usually be removed from the abdomen by suctioning out the bile and then removing the deflated gallbladder through the 1 cm incision at the patient's navel. The length of postoperative stay in the hospital is minimal, and same-day discharges are possible in cases of early morning procedures.[citation needed]

Varicose veins are generally benign. The cause of this condition is not known. For many people, there are no symptoms and varicose veins are simply a cosmetic concern. In some cases, they cause aching pain and discomfort or signal an underlying circulatory problem. Treatment involves compression stockings, exercise, or procedures to close or remove the veins.

Both lower extremities must be evaluated to determine the presence or extent of any disease and to ascertain the pulse status of the patient. The feet are examined for signs of peripheral vascular disease and the anterior and posterior tibial pulses are palpated. Because an intact arch can supply retrograde flow to the major vessels of the foot, it can be helpful to put pressure on the anterior tibial artery when detecting the presence of a posterior tibial pulse and visa-versa. This "modified Allen's test" may detect proximal vessel obstruction masked by an intact foot arch. The need for preoperative angiography in young, healthy patients with a normal physical examination has been hotly debated. Our tendency has been to obtain preoperative angiograms as a guide. Although rare, we have seen lower extremities with a dominant peroneal artery nourishing the foot and distal anterior and posterior vessels, contraindicating sacrifice of the peroneal artery. MRI or CT angiography can also be used in many circumstances.

Buerger Disease
Buerger Disease samer kareem 1,393 Views • 2 years ago

Buerger's disease (thromboangiitis obliterans) is a rare disease of the arteries and veins in the arms and legs. In Buerger's disease, your blood vessels become inflamed, swell and can become blocked with blood clots (thrombi). This eventually damages or destroys skin tissues and may lead to infection and gangrene. Buerger's disease usually first shows in your hands and feet and may eventually affect larger areas of your arms and legs. Virtually everyone diagnosed with Buerger's disease smokes cigarettes or uses other forms of tobacco, such as chewing tobacco. Quitting all forms of tobacco is the only way to stop Buerger's disease. For those who don't quit, amputation of all or part of a limb is sometimes necessary.

Hepatitis A and B
Hepatitis A and B samer kareem 4,284 Views • 2 years ago

Hepatitis is an inflammation of the liver. The condition can be self-limiting or can progress to fibrosis (scarring), cirrhosis or liver cancer. Hepatitis viruses are the most common cause of hepatitis in the world but other infections, toxic substances (e.g. alcohol, certain drugs), and autoimmune diseases can also cause hepatitis. There are 5 main hepatitis viruses, referred to as types A, B, C, D and E. These 5 types are of greatest concern because of the burden of illness and death they cause and the potential for outbreaks and epidemic spread. In particular, types B and C lead to chronic disease in hundreds of millions of people and, together, are the most common cause of liver cirrhosis and cancer. Hepatitis A and E are typically caused by ingestion of contaminated food or water. Hepatitis B, C and D usually occur as a result of parenteral contact with infected body fluids. Common modes of transmission for these viruses include receipt of contaminated blood or blood products, invasive medical procedures using contaminated equipment and for hepatitis B transmission from mother to baby at birth, from family member to child, and also by sexual contact. Acute infection may occur with limited or no symptoms, or may include symptoms such as jaundice (yellowing of the skin and eyes), dark urine, extreme fatigue, nausea, vomiting and abdominal pain.
