Tracheotomy Procedure Medical Animation
Tracheotomy Procedure Medical Animation Mohamed Ibrahim 38,989 Views • 2 years ago

Tracheotomy is a surgical procedure which consists of making an incision on the anterior aspect of the neck and opening a direct airway through an incision in the trachea (windpipe). The resulting stoma (hole), or tracheostomy, can serve independently as an airway or as a site for a tracheostomy tube to be inserted; this tube allows a person to breathe without the use of his or her nose or mouth. Both surgical and percutaneous techniques are widely used in current surgical practice. It is among the oldest described procedures.

Deep vein thrombosis (DVT) occurs when a blood clot (thrombus) forms in one or more of the deep veins in your body, usually in your legs. Deep vein thrombosis can cause leg pain or swelling, but may occur without any symptoms. Deep vein thrombosis can develop if you have certain medical conditions that affect how your blood clots. Deep vein thrombosis can also happen if you don't move for a long time, such as after surgery, following an accident, or when you are confined to a hospital or nursing home bed.

Living with Lewy Body Dementia - Mayo Clinic samer kareem 1,804 Views • 2 years ago

LBD is not a rare disease. It affects an estimated 1.4 million individuals and their families in the United States. Because LBD symptoms can closely resemble other more commonly known diseases like Alzheimer’s and Parkinson’s, it is currently widely underdiagnosed. Many doctors or other medical professionals still are not familiar with LBD. LBD is an umbrella term for two related diagnoses. LBD refers to both Parkinson’s disease dementia and dementia with Lewy bodies. The earliest symptoms of these two diseases differ, but reflect the same underlying biological changes in the brain. Over time, people with both diagnoses will develop very similar cognitive, physical, sleep, and behavioral symptoms. While it may take more than a year or two for enough symptoms to develop for a doctor to diagnose LBD, it is critical to pursue a formal diagnosis. Early diagnosis allows for important early treatment that may extend quality of life and independence. LBD is a multisystem disease and typically requires a comprehensive treatment approach. This approach involves a team of physicians from different specialties who collaborate to provide optimum treatment of each symptom without worsening other LBD symptoms. Many people with LBD enjoy significant improvement of their symptoms with a comprehensive approach to treatment, and some can have remarkably little change from year to year. Some people with LBD are extremely sensitive or may react negatively to certain medications used to treat Alzheimer’s or Parkinson’s in addition to certain over-the-counter medications.

Middle cerebral artery stroke - Axiom Neuro 3D Neurology and Neuroanatomy
Middle cerebral artery stroke - Axiom Neuro 3D Neurology and Neuroanatomy samer kareem 3,130 Views • 2 years ago

Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen. The MCA is the most common site for the occurrence of ischemic stroke.[1] Depending upon the location and severity of the occlusion, signs and symptoms may vary within the population affected with MCA syndrome. More distal blockages tend to produce milder deficits due to more extensive branching of the artery and less ischemic response. In contrast, the most proximal occlusions result in widespread effects that can lead to significant cerebral edema, increased intracranial pressure, loss of consciousness and could even be fatal.[1] In such occasions, mannitol (osmotic diuretic) or hypertonic saline are given to draw fluid out of the oedematus cerebrum to minimise secondary injury. Hypertonic saline is better than mannitol, as mannitol being a diuretic will decrease the mean arterial pressure and since cerebral perfusion is mean arterial pressure minus intracranial pressure, mannitol will also cause a decrease in cerebral perfusion. Contralateral hemiparesis and hemisensory loss of the face, upper and lower extremities is the most common presentation of MCA syndrome.[1] Lower extremity function is more spared than that of the faciobrachial region.[2] The majority of the primary motor and somatosensory cortices are supplied by the MCA and the cortical homunculus can, therefore, be used to localize the defects more precisely.it is important to note that middle cerebral artery lesions mostly affect the dominant hemisphere i.e. the left cerebral hemisphere.

Coronary Stent Procedure
Coronary Stent Procedure samer kareem 2,181 Views • 2 years ago

Before the angioplasty procedure begins, you will receive some pain medicine. You may also be given medicine that relaxes you, and blood thinning medicines to prevent a blood clot from forming. You will lie on a padded table. Your doctor will insert a flexible tube (catheter) through a surgical cut into an artery. Sometimes the catheter will be placed in your arm or wrist, or in your upper leg or groin area. You will be awake during the procedure. The doctor will use live x-ray pictures to carefully guide the catheter up into your heart and arteries. Dye will be injected into your body to highlight blood flow through the arteries. This helps the doctor see any blockages in the blood vessels that lead to your heart. A guide wire is moved into and across the blockage. A balloon catheter is pushed over the guide wire and into the blockage. The balloon on the end is blown up (inflated). This opens the blocked vessel and restores proper blood flow to the heart. A wire mesh tube (stent) may then be placed in this blocked area. The stent is inserted along with the balloon catheter. It expands when the balloon is inflated. The stent is left there to help keep the artery open

Aortic Aneurysm and Aortic Dissection
Aortic Aneurysm and Aortic Dissection samer kareem 5,471 Views • 2 years ago

An aortic dissection is a serious condition in which the inner layer of the aorta, the large blood vessel branching off the heart, tears. Blood surges through the tear, causing the inner and middle layers of the aorta to separate (dissect). If the blood-filled channel ruptures through the outside aortic wall, aortic dissection is often fatal. Aortic dissection is relatively uncommon. The condition most frequently occurs in men in their 60s and 70s. Symptoms of aortic dissection may mimic those of other diseases, often leading to delays in diagnosis. However, when an aortic dissection is detected early and treated promptly, the chance of survival greatly improves.

Hypocalcemia
Hypocalcemia samer kareem 1,355 Views • 2 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

Sickle Cell Anemia
Sickle Cell Anemia samer kareem 1,793 Views • 2 years ago

Sickle cell anemia is an inherited form of anemia — a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body. Normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body. There's no cure for most people with sickle cell anemia. However, treatments can relieve pain and help prevent further problems associated with sickle cell anemia.

Osteoporosis and How to prevent it
Osteoporosis and How to prevent it samer kareem 2,859 Views • 2 years ago

Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine. Bone is living tissue that is constantly being broken down and replaced. Osteoporosis occurs when the creation of new bone doesn't keep up with the removal of old bone. Osteoporosis affects men and women of all races. But white and Asian women — especially older women who are past menopause — are at highest risk. Medications, healthy diet and weight-bearing exercise can help prevent bone loss or strengthen already weak bones.

Breast Cancer Screening Recommendations Breast cancer screening is important for all women. If you are at higher risk of breast cancer, you may need to be screened earlier and more often than women at average risk. Breast cancer screening is only recommended for some men at very high risk due to an inherited gene mutation or a strong family history of breast cancer.

Constipation
Constipation samer kareem 1,852 Views • 2 years ago

Constipation is a common problem. It means either going to the toilet less often than usual to empty the bowels, or passing hard or painful stools (faeces). Constipation may be caused by not eating enough fibre, or not drinking enough fluids. It can also be a side-effect of certain medicines, or related to an underlying medical condition. In many cases, the cause is not clear. Laxatives are a group of medicines that can treat constipation. Ideally, laxatives should only be used for short periods of time until symptoms ease. Note: there is a separate leaflet on constipation in children. What is constipation? Constipation is common. If you are constipated it causes one or more of the following: Stools (faeces) become hard and difficult or painful to pass. The time between toilet trips increases compared with your usual pattern. (Note: there is a large range of normal bowel habit. Some people normally go to the toilet to pass stools 2-3 times per day. For others, 2-3 times per week is normal. It is a change from your usual pattern that may mean that you are constipated.) Sometimes, crampy pains occur in the lower part of your tummy (abdomen) You may also feel bloated and feel sick if you have severe constipation. What are the causes of constipation? Known causes include the following: Not eating enough fibre (roughage) is a common cause. The average person in the UK eats about 12 g of fibre each day. But, 18 g per day is recommended by the British Nutrition Foundation. Fibre is the part of plant food that is not digested. It remains in your gut. It adds bulk to the stools (faeces) and helps your bowels to work well. Foods high in fibre include fruit, vegetables, cereals and wholemeal bread. Not drinking much may make constipation worse. Stools are usually soft and easily passed if you eat enough fibre and drink enough fluid. However, some people need more fibre and/or fluid than others in order to avoid constipation. Some special slimming diets are low in fibre and may cause constipation. Some medicines can cause constipation as a side-effect. Examples are painkillers (particularly those with codeine, such as co-codamol, or very strong painkillers, such as morphine), some antacids, some antidepressants (including amitriptyline) and iron tablets; however, there are many others. See the list of possible side-effects on the leaflet that comes with any medicine that you may be taking. Tell a doctor if you suspect a medicine is making you constipated. A change of medication may be possible. Various medical conditions can cause constipation. For example, an underactive thyroid gland, irritable bowel syndrome, some gut disorders and conditions that cause poor mobility, particularly in the elderly. Pregnancy. About 1 in 5 pregnant women will become constipated. It is due to the hormonal changes of pregnancy that slow down the gut movements. In later pregnancy, it can simply be due to the baby taking up a lot of room in the tummy and the bowels being pushed to one side.

Thalassemia
Thalassemia samer kareem 1,425 Views • 2 years ago

Thalassemia is an inherited blood disorder characterized by less hemoglobin and fewer red blood cells in your body than normal. Several types of thalassemia exist, including alpha-thalassemia, beta-thalassemia intermedia, Cooley's anemia and Mediterranean anemia. Hemoglobin is the substance in your red blood cells that allows them to carry oxygen. The low hemoglobin and fewer red blood cells of thalassemia may cause anemia, leaving you fatigued. If you have mild thalassemia, you may not need treatment. But, if you have a more severe form of thalassemia, you may need regular blood transfusions. You can also take steps on your own to cope with fatigue, such as choosing a healthy diet and exercising regularly.

OverviewSymptomsTestingComplicationsTreatmentPreventionTakeawayRead This Next What is gonorrhea? Highlights Some people may never develop noticeable symptoms. Gonorrhea is usually treated with an antibiotic injection or oral antibiotics. You’re at a higher risk of contracting gonorrhea if you’ve had any other STDs. Gonorrhea is a sexually transmitted disease (STD). It’s caused by infection with the bacterium Neisseria gonorrhoeae. It tends to infect warm, moist areas of the body, including the: urethra (the tube that drains urine from the urinary bladder) eyes throat vagina anus female reproductive tract (the fallopian tubes, cervix, and uterus) Gonorrhea passes from person to person through unprotected oral, anal, or vaginal sex. People with numerous sexual partners or those who don’t use a condom are at greatest risk of infection. The best protections against infection are abstinence, monogamy (sex with only one partner), and proper condom usage. Behaviors that make a person more likely to engage in unprotected sex also increase the likelihood of infection. These behaviors include alcohol abuse and illegal drug abuse, particularly intravenous drug use. Advertisement Symptoms of gonorrhea Symptoms

Brachial-basilic AV fistula
Brachial-basilic AV fistula samer kareem 41,965 Views • 2 years ago

Autologous arteriovenous access is the key to long-term success with hemodialysis and is strongly supported by the National Kidney Foundation's Dialysis Outcomes Quality Initiative guidelines. Basilic vein transposition (BVT) fulfills the need for a durable conduit with high patency and maturation rates. This retrospective review examines a single group's experience with this procedure. All patients undergoing BVT for hemodialysis with available follow-up data were reviewed. Telephone interviews were used to supplement clinical data where needed. Functional assisted patency was used as the end point for this procedure, and if the access was never used for dialysis, then the patency was considered zero. Secondary interventions performed while the access remained patent and in use were not considered detrimental to the patency reported. One hundred seventy BVTs in 162 patients were performed between November 1992 and October 2001. There were 87 women (53.7%) and 112 black patients (69.1%); hypertension was present in 138 patients (85.2%) and diabetes in 89 patients (54.9%). Each year, an increasing incidence of BVT was performed in our dialysis population. The BVT was performed as the first access in that extremity in 73 of the procedures (42.9%). Functional patency (primary assisted) was achieved in 40.0% at 2 years and 15.2% at 5 years. The mean assisted patency was 14.6 months. To maintain BVT patency, 40 percutaneous secondary interventions (69.0%) and 18 surgical revisions (31.0%) occurred in 32 patients (19.0%). Ligation for swelling was necessary in 4 patients (2.5%), and steal syndrome occurred in 3 patients (1.9%). BVT is a useful autologous procedure for hemodialysis and the preferred access alternative in patients without an adequate cephalic vein. Although patencies remain poor relative to other conventional arterial vascular procedures, BVT is our most durable hemodialysis access procedure and is often the only available autologous conduit for hemodialysis.

Obstruction Lung Disease
Obstruction Lung Disease samer kareem 1,793 Views • 2 years ago

Obstructive lung disease is a category of respiratory disease characterized by airway obstruction. Many obstructive diseases of the lung result from narrowing of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself. It is generally characterized by inflamed and easily collapsible airways, obstruction to airflow, problems exhaling and frequent medical clinic visits and hospitalizations. Types of obstructive lung disease include; asthma, bronchiectasis, bronchitis and chronic obstructive pulmonary disease (COPD). Although COPD shares similar characteristics with all other obstructive lung diseases, such as the signs of coughing and wheezing, they are distinct conditions in terms of disease onset, frequency of symptoms and reversibility of airway obstruction.[1] Cystic fibrosis is also sometimes included in obstructive pulmonary disease
