Renal Artery Aneurysm Repair
Renal Artery Aneurysm Repair samer kareem 7,336 Views • 2 years ago

Indications for intervention in patients with a renal artery aneurysm (RAA) include the following [20, 8, 13, 14] : Rupture Symptomatic RAA - Hypertension (from associated renal artery stenosis, refractory to medical management), pain, renal ischemia or infarction secondary to embolization from the aneurysm sac RAAs in females who are pregnant or are contemplating pregnancy Diameter greater than 2 cm Enlarging RAA RAA associated with acute dissection Currently, there is no consensus regarding the size at which an RAA should be repaired in an asymptomatic patient. Experts have recommended RAA repair at diameters ranging from 1.5 to 3 cm, [8] though most suggest 2 cm. Some reports have even suggest that larger asymptomatic saccular aneurysms may be managed expectantly. Note that aneurysm rupture at a diameter of 1.5 cm has been reported. Complete calcification of the wall of the aneurysm sac manifests in about 40% of patients. This was once believed to confer protection against rupture [21] ; however, this belief has since been questioned. [30] Asymptomatic, small (<2 cm in diameter) RAAs do not usually require treatment. One notable exception is an RAA in a woman who is pregnant or contemplating pregnancy. In view of the increased risk of rupture in such cases, even small asymptomatic aneurysms should be repaired in this population. For diagnosis and preinterventional planning, gadolinium-enhanced magnetic resonance angiography (MRA) and computed tomography (CT) angiography (CTA) with three-dimensional (3D) reconstruction have essentially replaced conventional arteriography. Regular follow-up examination with ultrasonography (US) or CT) is recommended in patients who are treated expectantly. Spontaneous cure by thrombosis of small aneurysms has been described. Further refinements in endovascular techniques may allow more RAAs to be treated in this manner. So far, excellent short- and intermediate-term results have been described in the literature [40] ; however, there remains a need for further long-term outcome data.

How to Get Rid of The Bad Smell in The Pubic Area samer kareem 55,209 Views • 2 years ago

Odor is a topic that’s not only embarrassing to discuss for many, but it’s simply embarrassing to live with for anyone who may be experiencing it. Oftentimes, it’s the result of a vaginal yeast infection, but that’s not always the case — which is why it’s important to find the root cause. Having a healthy vagina is extremely important to overall health, healthy births and healthy marriages, and vaginal odor can be a signal that there might be a health issue at play. How this affects a woman’s self-esteem is another side effect, not to mention how it can affect her relationship with her significant other due to the impact it may have on their sex life. While there are many causes, most of the time it can be resolved through natural remedies. But where does this incredibly uncomfortable vaginal odor come from, and what is it in the first place? Vaginal odor is defined as any odor that originates from the vagina. It’s normal for your vagina to have a slight odor given it’s an opening to the interior of the body, but a strong vaginal smell, such as a fishy vaginal odor, could indicate a bigger problem and should be checked out with your physician.

What is myositis? Myositis means muscle inflammation, and can be caused by infection, injury, certain medicines, exercise, and chronic disease. Some of the chronic, or persistent, forms are idiopathic inflammatory myopathies, and those are the diseases we discuss here. "Idiopathic" means that the cause is unknown.

Tonsillitis
Tonsillitis samer kareem 2,401 Views • 2 years ago

Tonsillitis is inflammation of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side. Signs and symptoms of tonsillitis include swollen tonsils, sore throat, difficulty swallowing and tender lymph nodes on the sides of the neck. Most cases of tonsillitis are caused by infection with a common virus, but bacterial infections also may cause tonsillitis. Because appropriate treatment for tonsillitis depends on the cause, it's important to get a prompt and accurate diagnosis. Surgery to remove tonsils, once a common procedure to treat tonsillitis, is usually performed only when bacterial tonsillitis occurs frequently, doesn't respond to other treatments or causes serious complications.

Esophageal Atresia
Esophageal Atresia samer kareem 4,693 Views • 2 years ago

Esophageal atresia is an abnormality, or birth defect, of the esophagus that occurs early in pregnancy, as the baby is developing. The esophagus forms in the first few months of fetal life as a long, hollow, continuous tube joining the mouth to the stomach. In newborns with this birth defect, formation of this continuous esophageal tube is interrupted. esophageal-artresia-2In most cases, two separate tubes are formed, an upper (proximal) tube connected to the mouth and a lower (distal) tube connected to the stomach. This seperated tubes are sealed off creating a pouch on either side; the gap between these pounches can be short or very long. Saliva can accumulate in the upper pouch as it cannot drain into the stomach.

Stapling is used to treat prolapsed hemorrhoids. A surgical staple fixes the prolapsed hemorrhoid back into place inside your rectum and cuts off the blood supply so that the tissue will shrink and be reabsorbed. Stapling recovery takes less time and is less painful than recovery from a hemorrhoidectomy.

Spleen
Spleen samer kareem 5,345 Views • 2 years ago

The spleen, a spongy, soft organ about as big as a person’s fist, is located in the upper left part of the abdomen, just under the rib cage. The splenic artery brings blood to the spleen from the heart. Blood leaves the spleen through the splenic vein, which drains into a larger vein (the portal vein) that carries the blood to the liver. The spleen has a covering of fibrous tissue (the splenic capsule) that supports its blood vessels and lymphatic vessels. The spleen is made up of two basic types of tissue, each with different functions: White pulp Red pulp The white pulp is part of the infection-fighting (immune) system. It produces white blood cells called lymphocytes, which in turn produce antibodies (specialized proteins that protect against invasion by foreign substances). The red pulp filters the blood, removing unwanted material. The red pulp contains other white blood cells called phagocytes that ingest microorganisms, such as bacteria, fungi, and viruses. It also monitors red blood cells, destroying those that are abnormal or too old or damaged to function properly. In addition, the red pulp serves as a reservoir for different elements of the blood, especially white blood cells and platelets (cell-like particles involved in clotting). However, releasing these elements is a minor function of the red pulp.

If both the pCO2 and HCO3 are abnormal, the one which deviates most from the norm is most likely causing an abnormal pH. Check the pO2. Is the patient hypoxic?

Endoscopic Dacryocystorhinostomy
Endoscopic Dacryocystorhinostomy samer kareem 7,137 Views • 2 years ago

Dacryocystorhinostomy (DCR) is a procedure performed for the treatment of tearing (epiphora) due to blockage of the nasolacrimal duct. Tears originate in the lacrimal gland, located at the upper outer margin of the eye. As tears cross the eye with each blink, they are directed into small openings in the eyelids called puncta. From this point, tears travel through a pathway known as the canalicular system into the lacrimal sac. The lacrimal sac is located between the eye and the nose, and funnels tears into the nasal cavity through the nasolacrimal duct (Figure 1). As this is quite a long path for tears to travel, there can be many causes of excessive tearing. Blockage of the nasolacrimal duct is one common cause, and can be treated by creating a direct opening from the lacrimal sac into the nasal cavity in a procedure known as DCR. The evaluation and management of tearing may involve both an ophthalmologist and an otolaryngologist.

Transposition of the Great Arteries
Transposition of the Great Arteries samer kareem 7,667 Views • 2 years ago

Transposition of the great arteries is a serious but rare heart defect present at birth (congenital), in which the two main arteries leaving the heart are reversed (transposed). Transposition of the great arteries changes the way blood circulates through the body, leaving a shortage of oxygen in blood flowing from the heart to the rest of the body. Without an adequate supply of oxygen-rich blood, the body can't function properly and your child faces serious complications or death without treatment.
