Aplastic anemia: causes, diagnosis and managment
Aplastic anemia: causes, diagnosis and managment samer kareem 1,361 Views • 3 years ago

Aplastic anemia is a hematopoietic disorder caused due to T lymphocyte mediated destruction of stem cells resulting in pancytopenia with a cellular bone marrow and normal cell cytogenetics. The causes of aplastic anaemia may be inherited or acquired. The causes and the diagnostic approach, along with spectrum of severity of this disorder is discussed in this presentation. A detailed discussion of the management options, along with pharmacological therapy and supportive therapy in these cases is also discussed. The treatment options include, in addition to a stem cell transplant, anti-thymocyte globulin, cyclosporine, methyprednisolone and eltrombopag (for patients who have failed treatment on combined modality therapy with ATG and cyclosporine)

Follicle Development and Ovulation! samer kareem 4,171 Views • 3 years ago

Before ovulation occurs, the average diameter of the dominant follicle is 22 to 24 mm (range 18-36 mm). It is the only marker that can predict ovulation with ease. * In stimulated cycle (hormonal treatment), generally, all or most of the antral follicles grow. The growth rate will be different for each of them.

Pulmonary Artery Catheterization
Pulmonary Artery Catheterization samer kareem 1,634 Views • 3 years ago

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.

The hepatic portal system is the system of veins comprising the hepatic portal vein and its tributaries. It is responsible for directing blood from the region of the gastrointestinal tract between the esophagus and rectum and also includes venous drainage from the supplementary organs such as the spleen and pancreas.

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. Physical therapy and medications that suppress the immune system can help with symptoms and slow disease progression.
