A good starting point for any scientist in any field is to recognize that there is much we do not know. We do not know, for example, why there is more matter than antimatter in the universe. We do not know very well how the evolution of the dinosaurs filtered out. And, perhaps most surprising of all is that we do not know very well how many organs the human body has or what all its functions are.

Hypoglycaemia: causes, features and management
Hypoglycaemia: causes, features and management samer kareem 1,012 Views • 3 years ago

Hypoglycemia is a common and serious medical emergency which may occur in both daibetic and non-diabetic patients. The signs and symptoms of hypoglycaemia may be present in many individuals, but may also be masked in several individuals due to a condition called hypoglycaemia induced autonomic failure. This presentation aims to deal with the causes, clinical features, diagnosis and management of various causes of hypoglycaemia. The causes of hypoglycaemia may be divided into hypoglycaemia in ill or medicated individuals and hypoglycaemia in previously asymptomatic individuals. A variety of causes are discussed under both headings. Management of hypoglycaemia is also discussed in detail. There is also a brief discussion about management of insulinoma.

Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing. A variety of organisms, including bacteria, viruses and fungi, can cause pneumonia.

Capsaicin binds to pain receptors on our nerves called TRPV1. Normally, it reacts to heat by sending warning signals to the brain. Capsaicin causes TRPV1 to send those same signals. So, you react as if there's something hot in your mouth

Oral Exam
Oral Exam Scott 26,733 Views • 3 years ago

The exam should be performed in an orderly fashion as follows: 1. Have the patient stick out their tongue so that you can examine the posterior pharynx (i.e. the back of the throat). Ask the patient to say "Ah", which elevates the soft palate, giving you a better view. If you are still unable to see, place the tongue blade � way back on the tongue and press down while the patient again says "Ah," hopefully improving your view. This causes some people to gag, particularly when the blade is pushed onto the more proximal aspects of the tongue. It may occasionally be important to determine whether the gag reflex is functional (e.g. after a stroke that impairs CNs 9 or 10; or to determine if a patient with depressed level of consciousness is able to protect their airway from aspiration). This is done by touching a q-tip against the posterior pharynx, uvula or tongue. It is not necessary to do this during your routine exam as it can be quite noxious!
2. Note that the uvula hangs down from the roof of the mouth, directly in the mid-line. With an "Ah," the uvula rises up. Deviation to one side may be caused by CN 9 palsy (the uvula deviates away from the affected side), a tumor or an infection. CN9 Pasly Cranial Nerve 9 Dysfunction: Patient has suffered stroke, causing loss of function of left CN 9. As a result, uvula is pulled towards the normally functioning (ie right) side. 3. The normal pharynx has a dull red color. In the setting of infection, it can become quite red, frequently covered with a yellow or white exudate (e.g. with Strep. Throat or other types of pharyngitis).
4. The tonsils lie in an alcove created by arches on either side of the mouth. The apex of these arches are located lateral to and on a line with the uvula. Normal tonsils range from barely apparent to quite prominent. When infected, they become red, are frequently covered by whitish/yellow discharge. In the setting of a peritonsilar abscess, the tonsils appear asymmetric and the uvula may be pushed away from the affected side. When this occurs, the tonsil may actually compromise the size of the oral cavity, making breathing quite difficult.
5. Look carefully along the upper and lower gum lines and at the mucosa in general, which can appear quite dry if the patient is dehydrated.
6. Examine the teeth to get a sense of general dentition, particularly if the patient has a dental complaint. Pain produced by tapping on a tooth is commonly caused by a root abscess. Tooth Abscess: Tooth abscess involving left molar region. Associated inflammation of left face can clearly be seen. 7. Have the patient stick their tongue outside their mouth, which allows evaluation of CN 12. If there is nerve impairment, the tongue will deviate towards the affected side. Any obvious growths or abnormalities? Ask them to flip their tongue up so that you can look at the underside. If you see something abnormal, grasp the tongue with gauze so that you can get a better look. Left CN 12 Dysfunction: Stroke has resulted in L CN 12 Palsy. Tongue therefore deviates to the left.
8. Make note of any growths along the cheeks, hard palate (the roof of the mouth between the teeth), soft palate, or anywhere else. In particular, patients who smoke or chew tobacco are at risk for oral squamous cell cancer. Any areas which are painful or appear abnormal should also be palpated. Put on a pair of gloves to better explore these regions. What do they feel like? Are they hard? To what extent does a growth involve deeper structures? If the patient feels something that you cannot see, try to get someone else to hold the light source, freeing both your hands to explore the oral cavity with two tongue depressors.

Diplegic Gait Demonstration
Diplegic Gait Demonstration samer kareem 1,911 Views • 3 years ago

The patient has spasticity in the lower extremities greater than the upper extremities. The hips and knees are flexed and adducted with the ankles extended and internally rotated. When the patient walks both lower extremities are circumducted and the upper extremities are held in a mid or low guard position. This type of gait is usually seen with bilateral periventricular lesions. The legs are more affected than the arms because the corticospinal tract axons that are going to the legs are closest to the ventricles.

Stem Cell Injection Alternative to Surgery
Stem Cell Injection Alternative to Surgery samer kareem 5,543 Views • 3 years ago

Adult stem cells are cells from your own body that can renew themselves and turn into other cells (differentiate). They live inside all of us in various tissues, poised to leap into action to repair damage as it occurs. As we age or have big injuries, we may not be able to recruit enough of these cells to the site to fully repair the area. Regenexx Stem Cell Procedures help overcome this problem by extracting stem cells from an area of high volume, then concentrating the cells and reinjecting them into the damaged area to help the body heal naturally.
