Gallstones are hardened deposits of digestive fluid that can form in your gallbladder. Your gallbladder is a small, pear-shaped organ on the right side of your abdomen, just beneath your liver. The gallbladder holds a digestive fluid called bile that's released into your small intestine. Gallstones range in size from as small as a grain of sand to as large as a golf ball. Some people develop just one gallstone, while others develop many gallstones at the same time. Gallstones are common in the United States. People who experience symptoms from their gallstones usually require gallbladder removal surgery. Gallstones that don't cause any signs and symptoms typically don't need treatment.

The examination consists of three portions: Inspection, Palpation, and Synthesis of data from these techniques In addition to palpating for size, also note the gland texture, mobility, tenderness and the presence of nodules. Inspection Inspection: Anterior Approach The patient should be seated or standing in a comfortable position with the neck in a neutral or slightly extended position. Cross-lighting increases shadows, improving the detection of masses. To enhance visualization of the thyroid, you can: Extending the neck, which stretches overlying tissues Have the patient swallow a sip of water, watching for the upward movement of the thyroid gland. quicktime video 251KB video demo from Return to the Bedside Inspection: Lateral Approach After completing anterior inspection of the thyroid, observe the neck from the side. Estimate the smooth, straight contour from the cricoid cartilage to the suprasternal notch. Measure any prominence beyond this imagined contour, using a ruler placed in the area of prominence. Palpation Note: There is no data comparing palpation using the anterior approach to the posterior approach so examiners should use the approach that they find most comfortable. Palpation: Anterior Approach placement of hands for palpatation of thyroid in anterior approach The patient is examined in the seated or standing position. Attempt to locate the thyroid isthmus by palpating between the cricoid cartilage and the suprasternal notch. Use one hand to slightly retract the sternocleidomastoid muscle while using the other to palpate the thyroid. Have the patient swallow a sip of water as you palpate, feeling for the upward movement of the thyroid gland. quicktime video 454KB video demo from Return to the Bedside. Palpation: Posterior Approach placement of hands for palpatation of thyroid in posterior approach The patient is examined in the seated or standing position. Standing behind the patient, attempt to locate the thyroid isthmus by palpating between the cricoid cartilage and the suprasternal notch. Move your hands laterally to try to feel under the sternocleidomstoids for the fullness of the thyroid. Have the patient swallow a sip of water as you palpate, feeling for the upward movement of the thyroid gland.

Diabetes insipidus (die-uh-BEE-teze in-SIP-uh-dus) is an uncommon disorder that causes an imbalance of water in the body. This imbalance leads to intense thirst even after drinking fluids (polydipsia), and excretion of large amounts of urine (polyuria). While the names diabetes insipidus and diabetes mellitus sound similar, they're not related. Diabetes mellitus โ€” which can occur as type 1 or type 2 โ€” is the more common form of diabetes. There's no cure for diabetes insipidus, but treatments are available to relieve your thirst and normalize your urine output.

There are twelve cranial nerves in total. The olfactory nerve (CN I) and optic nerve (CN II) originate from the cerebrum. Cranial nerves III โ€“ XII arise from the brain stem (Figure 1). They can arise from a specific part of the brain stem (midbrain, pons or medulla), or from a junction between two parts: Midbrain โ€“ the trochlear nerve (IV) comes from the posterior side of the midbrain. It has the longest intracranial length of all the cranial nerves. Midbrain-pontine junction โ€“ oculomotor (III). Pons โ€“ trigeminal (V). Pontine-medulla junction โ€“ abducens, facial, vestibulocochlear (VI-VIII). Medulla Oblongata โ€“ posterior to the olive: glossopharyngeal, vagus, accessory (IX-XI). Anterior to the olive: hypoglossal (XII). The cranial nerves are numbered by their loca

An atrioventricular septal defect (AVSD) is a heart defect in which there are holes between the chambers of the right and left sides of the heart, and the valves that control the flow of blood between these chambers may not be formed correctly. This condition is also called atrioventricular canal (AV canal) defect or endocardial cushion defect. In AVSD, blood flows where it normally should not go. The blood may also have a lower than normal amount of oxygen, and extra blood can flow to the lungs. This extra blood being pumped into the lungs forces the heart and lungs to work hard and may lead to
