Multiple Sclerosis: Signs, Symptoms and Treatments
Multiple Sclerosis: Signs, Symptoms and Treatments samer kareem 1,088 Views • 3 years ago

Multiple sclerosis causes many different symptoms, including vision loss, pain, fatigue, and impaired coordination. The symptoms, severity, and duration can vary from person to person. Some people may be symptom free most of their lives, while others can have severe chronic symptoms that never go away.

The abortion pill is a medicine called mifepristone that ends an early pregnancy.In general, it's used up to 70 days — 10 weeks — after the first day of a woman's last period. Patients over this mark can have an in-clinic abortion procedure.

Carotid Endarterectomy Approach
Carotid Endarterectomy Approach samer kareem 4,325 Views • 3 years ago

The objective of carotid endarterectomy (CEA) is to prevent strokes. In the United States, stroke is the third leading cause of death overall and the second leading cause of death for women.[1] Among patients suffering a stroke, 50-75% had carotid artery disease that would have been amenable to surgical treatment. Several prospective randomized trials have compared the safety and efficacy of CEA with those of medical therapy in symptomatic and asymptomatic patients. Data from these prospective trials have confirmed that CEA offers better protection from ipsilateral strokes than medical therapy alone in patients presenting with either symptomatic or asymptomatic carotid artery disease.

Pulmonary Artery Catheterization

Any independent vertical movement of the transducer or the patient will affect the hydrostatic column of this fluid-filled system and thus alter the pressure measurements. At some time before or after PAC insertion, the system must therefore be zeroed to ambient air pressure. The reference point for this is the midpoint of the left atrium (LA), estimated as the fourth intercostal space in the midaxillary line with the patient in the supine position. With the transducer at this height, the membrane is exposed to atmospheric pressure, and the monitor is then adjusted to zero. Calibration Once zeroed, the monitoring system must be calibrated for accuracy. Currently, most monitors perform an automated electronic calibration. Two methods are used to manually calibrate and check the system. If the catheter has not been inserted, the distal tip of the PAC is raised to a specified height above the LA. For example, raising the tip 20 cm above the LA should produce a reading of approximately 15 mm Hg if the system is working properly (1 mm Hg equals 1.36 cm H 2 O). Alternatively, pressure can be applied externally to the transducer and adjusted to a known level using a mercury or aneroid manometer. The monitor then is adjusted to read this pressure, and the system is calibrated. Dynamic tuning Central pressures are dynamic waveforms (ie, they vary from systole to diastole) and thus have a periodic frequency. To monitor these pressures accurately, the system requires an appropriate frequency response. A poorly responsive system produces inaccurate pressure readings, and differentiating waveforms (eg, PA from pulmonary capillary wedge pressure [PCWP]) can become difficult. When signal energy is lost, the pressure waveform is dampened. Common causes of this are air bubbles (which are compressible), long or compliant tubing, vessel wall impingement, intracatheter debris, transducer malfunction, and loose connections in the tubing. A qualitative test of the frequency response is performed by flicking the catheter and observing a brisk high-frequency response in the waveform. After insertion, the system can be checked by using the rapid flush test. When flushed, an appropriately responsive system shows an initial horizontal straight line with a high-pressure reading. Once the flushing is terminated, the pressure drops immediately, which is represented by a vertical line that plunges below the baseline. A brief and well-defined oscillation occurs, followed by return of the PA waveform. A dampened system will not overshoot or oscillate, and causes a delay in returning to the PA waveform.

A detailed description of the Hepato-pulmonary syndrome including its definition, pathophysiology, diagnosis and treatment. The pathophysiology includes nitric oxide in the pulmonary vasculature which results in intrapulmonary vasodilatation. This causes the classical and unique symptom of platypnea and orthodeoxia.

Internal Jugular Cannulation samer kareem 4,643 Views • 3 years ago

In caring for patients who are critically ill, access to the central venous circulation is important. Central venous access allows the placement of various types of intravenous (IV) lines to facilitate the infusion of fluids, blood products, and drugs and to obtain blood for laboratory analysis. It is also an essential procedure in patients in whom placement of a line in a peripheral vein is impossible. A central line may be the only means of venous access in such cases.

One Year Later: First Bilateral Hand Transplant in a Child Surgeon 4,731 Views • 3 years ago

Surgeons at The Children’s Hospital of Philadelphia were the first to perform a bilateral hand transplant on a child. Our research and work in this groundbreaking field of medicine led us to establish the Hand Transplantation Program. Combining the expertise of the Penn Transplant Institute and the Hospital’s Division of Plastic and Reconstructive Surgery and Division of Orthopedics, the program aims to improve quality of life for children who may benefit from this procedure. This is Zion, one year after the surgery

The Symptoms and Signs You May Have a Blood Clot
The Symptoms and Signs You May Have a Blood Clot samer kareem 1,472 Views • 3 years ago

They might not sound very life threatening, but a blood clot that develops in the deep veins of your leg, if left untreated and unable to dissolve of its own volition, may detach and travel to your lungs, causing a pulmonary embolism (or PE). In most cases, a leg blood clot will form due to lengthy periods of travel, for example if you remain immobile in cramped spaces—such as an airplane or bus—with few opportunities to stretch your legs or get up and walk around. Here are ten signs that you may have a dangerous blood clot in your leg
