Bone marrow biopsy and bone marrow aspiration are procedures to collect and examine bone marrow — the spongy tissue inside some of your larger bones. Bone marrow biopsy and aspiration can show whether your bone marrow is healthy and making normal amounts of blood cells. Doctors use these procedures to diagnose and monitor blood and marrow diseases, including some cancers, as well as fevers of unknown origin. Bone marrow has a fluid portion and a more solid portion. In bone marrow biopsy, your doctor uses a needle to withdraw a sample of the solid portion. In bone marrow aspiration, a needle is used to withdraw a sample of the fluid portion.

The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.

A new well designed randomized study has suggested that long term baby aspirin usage may aid in fight against cancer. The suggested mechanism is that cancers induce inflammatory responses so the anti-inflammatory mechanism of prostaglandins inhibitors may cease the progress of many cancers. There are some concerns about the study because despite the well-designed randomized study; the study didn't include a satisfying number of female participants. The study was also conducted on esophageal, colorectal and lung cancers.

While an anal abscess is an infection within one or more of the anal spaces, an anal fistula (Choice B) is a tunneling between the anus or rectum and another epithelial lined space (eg, the skin overlying the drainage site). Fifty percent of patients with anal abscesses will go on to develop a chronic fistula from the involved anal gland to the overlying skin. Patients with fistulas typically present with an anal abscess that persists after incision and drainage, or with a pustule-like lesion in the perianal or ischiorectal area that continually drains. Surgical repair is usually necessary to eliminate the fistula while preserving fecal continence.

This is a surgical video that shows the removal of a volar ganglion cyst. This is a common surgical procedure and this video may help you better understand the steps that occur during the procedure.

St. John's wort (Hypericum perforatum) is an over-the-counter herbal supplement used for its antidepressant, anti-inflammatory, and wound-healing properties. Although it has been prescribed in Europe for mild to moderate depression, negative clinical trials and multiple reports of adverse drug interactions have raised concern about its use. St. John's wort induces various P450 isozymes (CYP 1A2, 2C19, 2C9, and 3A4) and P-glycoprotein systems. Drug interactions with the herbal product can lead to treatment failures with many medications, including hormonal contraceptives, antiretrovirals, immunosuppressive agents, narcotics, anticoagulants, and antifungals. There is also a risk for serotonin syndrome when St. John's wort is used in combination with other serotonergic antidepressants. The lack of strict regulation of herbal products that results in variable quality and content (unknown toxic ingredients or inactive ingredients) is also a concern.

After the nose surgery the patients are advised to keep their nose taped for 2 weeks to 2 months. During the first two weeks, the surgery tapes influence both swelling and forming. From the second week on however, the nose tapes are applied just to reduce the swelling.

Peripheral Vascular Examination OSCE - Clinical Skills - Dr Gill

In the cardiovascular examination, particularly in the case of an OSCE station, we conclude the examination often by stating that the examiner would want to perform:
- An ECG
- Check full blood count
- and "do a peripheral vascular examination

In this video, we demonstrate that oft-talked about, but comparatively less common examination.

Starting off, with the examination of the hands, the radial, brachial and carotid pulses. before moving down to assess for a AAA, checking the femoral and popliteal pulses, before wrapping up around the ankle with the posterior tibial and dorsalis pedis pulses

The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions. First, for those impatient, short answers to the mini-questions (if you're reading this in the news feed, you may want to click through for the question details): No one knows why we evolved 2 kidneys and one liver.

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.

Diarrhea in Children: Common Causes and Treatments Diarrhea is the body's way of ridding itself of germs, and most episodes last a few days to a week. Diarrhea often occurs with fever, nausea, vomiting, cramps, and dehydration. Some of the most common reasons kids get diarrhea include: Infection from viruses like rotavirus, bacteria like salmonella and, rarely, parasites like giardia. Viruses are the most common cause of a child's diarrhea. Along with loose or watery stools, symptoms of a viral gastroenteritis infection often include vomiting, stomachache, headache, and fever. When treating viral gastroenteritis -- which can last 5-14 days -- it's important to prevent fluid loss. Offer additional breast milk or an oral rehydration solution (ORS) to infants and young children. Water alone doesn't have enough sodium, potassium, and other nutrients to safely rehydrate very young children. Be sure to talk to your doctor about the amount of fluids your child needs, how to make sure he or she gets them, when to give them, and how to watch for dehydration. Older children with diarrhea can drink anything they like to stay hydrated, including ORS and brand-name products (their names usually end in "lyte"). Popsicles can also be a good way to get fluids into a child who's been vomiting and needs to rehydrate slowly.

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.
