Hypertensive Emergency
Hypertensive Emergency samer kareem 1,737 Views • 2 years ago

Hypertensive emergencies encompass a spectrum of clinical presentations in which uncontrolled blood pressures (BPs) lead to progressive or impending end-organ dysfunction. In these conditions, the BP should be lowered aggressively over minutes to hours. Neurologic end-organ damage due to uncontrolled BP may include hypertensive encephalopathy, cerebral vascular accident/cerebral infarction, subarachnoid hemorrhage, and/or intracranial hemorrhage.[1] Cardiovascular end-organ damage may include myocardial ischemia/infarction, acute left ventricular dysfunction, acute pulmonary edema, and/or aortic dissection. Other organ systems may also be affected by uncontrolled hypertension, which may lead to acute renal failure/insufficiency, retinopathy, eclampsia, or microangiopathic hemolytic anemia.[1] With the advent of antihypertensives, the incidence of hypertensive emergencies has declined from 7% to approximately 1% of patients with hypertension.[2] In addition, the 1-year survival rate associated with this condition has increased from only 20% (prior to 1950) to a survival rate of more than 90% with appropriate medical treatment

Ventricular Tachycardia
Ventricular Tachycardia samer kareem 2,997 Views • 2 years ago

Ventricular tachycardia is a type of heart rhythm disorder (arrhythmia) in which the lower chambers of your heart (ventricles) beat very quickly because of a problem in your heart's electrical system. In ventricular tachycardia, your heart may not be able to pump enough blood to your body and lungs because the chambers are beating so fast that they don't have time to properly fill. Ventricular tachycardia may be brief — lasting for just seconds and often not causing symptoms — or it can last for much longer, and you can develop symptoms such as dizziness or lightheadedness, or you can even pass out. This condition usually occurs in people with other heart conditions, such as coronary artery disease, cardiomyopathy and some types of valvular heart disease. Ventricular tachycardia may lead to a condition in which your lower heart chambers quiver (ventricular fibrillation), which may cause your heart to stop (sudden cardiac arrest) and lead to death if not treated immediately. Ventricular tachycardia can also cause your heart to stop, especially if the heart is beating very quickly, if it's lasting for a long period, and if you have an underlying heart condition.

Proximal femur & Hip Fixation
Proximal femur & Hip Fixation samer kareem 2,393 Views • 2 years ago

The lateral approach is used for insertion of fixation devices after closed reduction of a proximal femoral fracture. Reduction of a displaced fracture is usually done with a fracture table, or alternatively a large distractor spanning the hip joint. After satisfactory reduction is confirmed by image intensifier, the lateral approach can be used for insertion of a sliding hip screw or multiple screws. The approach provides limited access to the lateral surface of the femur sufficient for hardware placement. The incision can be extended proximally to accommodate a trochanteric stabilizing plate (TSP), or even anteriorly so that it becomes an anterolateral approach with direct, although limited, access to the femoral neck.

Symptoms B12 deficiency
Symptoms B12 deficiency samer kareem 5,920 Views • 2 years ago

Are you getting enough vitamin B12? Many people don’t, and that deficiency can cause some serious problems. Vitamin B12 does a lot of things for your body. It helps make your DNA and your red blood cells, for examples. Since your body doesn't make vitamin B12, you'll need to get it from animal-based foods or from supplements, and it needs to be consumed on a regular basis. Exactly how much you need and where you should get it from depends on things like your age, the diet you follow, your medical conditions, and in some cases what medications you take.

The shoulder joint is formed where the humerus (upper arm bone) fits into the scapula (shoulder blade), like a ball and socket. Other important bones in the shoulder include: The acromion is a bony projection off the scapula. The clavicle (collarbone) meets the acromion in the acromioclavicular joint.

In patients with advanced congestive heart failure due to cardiomyopathy or ischemia, right ventricle shortening is the only significant independent associate of survival by multivariate analysis (as opposed to other parameters including left ventricular ejection fraction, cardiac index, and pulmonary resistance).

Laparoscopic Sigmoid Colectomy
Laparoscopic Sigmoid Colectomy samer kareem 2,527 Views • 2 years ago

This operation can be performed as an open or laparoscopic (keyhole procedure). During the operation the sigmoid colon is removed. This involves taking away the blood vessels and lymph nodes to that part of the bowel. The surgeon then re-makes the join (anastomosis) between the remaining left side of the colon and the top of the rectum. The surgeon may use either sutures or special staples to make this join.

The Brain and Cranial Nerves
The Brain and Cranial Nerves samer kareem 21,606 Views • 2 years ago

The brain is that part of the CNS contained within the cranial cavity (figure 13.1). It is the control center for many of the body's functions. The brain is much like a complex central computer but with additional functions that no computer can as yet match. Indeed, one goal in computer technology is to make computers that can function more like the human brain. The brain consists of the brainstem, the cerebellum, the diencephalon, and the cerebrum (table 13.1). The brainstem includes the medulla oblongata, pons, midbrain, and reticular formation. The structure of the brain is described in this chapter. Its functions are primarily discussed in chapter 14. Twelve pairs of cranial nerves, which are part of the PNS, arise directly from the brain. Two pairs arise from the cerebrum, nine pairs arise from the brainstem, and one pair arises from the spinal cord.
