This minimally invasive technique allows surgeons to remove skull base tumors as large as softballs through the nose, with less trauma to the brain and critical nerves than with a traditional craniotomy.

This medical animation shows laparoscopically assisted gallbladder removal surgery, or cholecystectomy. The animation begins by showing the normal anatomy of the liver and gallbladder. Over time, gallstones form within the gallbladder, blocking the cystic duct, and causing the gallbladder to become enlarged and inflamed. The procedure, sometimes called a "lap-chole", begins with the insertion of four trocar devices, which allow the physician to see inside the abdomen without making a large incision. Air is added to the abdominal cavity to make it easier to see the gall bladder. Next, we see a view through the laparascope, showing two surgical instruments grasping the gallbladder while a third severs the cystic duct. After the gallbladder is removed, the camera pans around to show that the cystic artery and vein, have already been clipped to prevent bleeding.

In a normal person, when a muscle tendon is tapped briskly, the muscle immediately contracts due to a two-neuron reflex arc involving the spinal or brainstem segment that innervates the muscle. The afferent neuron whose cell body lies in a dorsal root ganglion innervates the muscle or Golgi tendon organ associated with the muscles; the efferent neuron is an alpha motoneuron in the anterior horn of the cord. The cerebral cortex and a number of brainstem nuclei exert influence over the sensory input of the muscle spindles by means of the gamma motoneurons that are located in the anterior horn; these neurons supply a set of muscle fibers that control the length of the muscle spindle itself. Hyporeflexia is an absent or diminished response to tapping. It usually indicates a disease that involves one or more of the components of the two-neuron reflex arc itself. Hyperreflexia refers to hyperactive or repeating (clonic) reflexes. These usually indicate an interruption of corticospinal and other descending pathways that influence the reflex arc due to a suprasegmental lesion, that is, a lesion above the level of the spinal reflex pathways.

Meningitis is a common life-threatening medical emergency caused by infectious and non-infectious agents. Rapid and accurate evaluation by history and clinical examination is helpful to guide further specific investigation and treatment. Kernig's sign, Brudzinski's sign, and nuchal rigidity are bedside diagnostic signs used to evaluate suspected cases of meningitis. The presence of meningeal irritation, however, is not pathognomonic for meningitis.

Bone is not a static part of the body — it's constantly being resorbed (broken down) and formed throughout your life. Your entire skeleton is replaced about every decade, according to the NIH. During your childhood and teenage years, bone formation occurs more quickly than bone resorption, resulting in growth. You reach your maximum bone density and strength around age 30, after which bone resorption slowly overtakes bone formation. Osteoporosis develops when there's an abnormal imbalance between bone resorption and formation — that is, resorption occurs too quickly, or formation too slowly.

The baby suffered from ectopia cordis, a rare condition where a baby's heart is located either partially or totally outside the chest. Only 8 out of 1 million babies are born with the condition, and 90 percent of those babies are either stillborn or die within the first three days of life.

Patent ductus arteriosus (PDA) is a persistent opening between two major blood vessels leading from the heart. The opening, called the ductus arteriosus, is a normal part of a baby's circulatory system before birth that usually closes shortly after birth. If it remains open, however, it's called a patent ductus arteriosus.

Vitamin E is an antioxidant. It may help protect your cells from damage. This essential nutrient occurs naturally in many foods. It’s also available as a dietary supplement. Sometimes, it’s in processed foods. Vitamin E is fat-soluble. This means your body stores and uses it as needed. The term “vitamin E” describes eight different compounds. Alpha-tocopherol is the most active one in humans

The spleen, a spongy, soft organ about as big as a person’s fist, is located in the upper left part of the abdomen, just under the rib cage. The splenic artery brings blood to the spleen from the heart. Blood leaves the spleen through the splenic vein, which drains into a larger vein (the portal vein) that carries the blood to the liver. The spleen has a covering of fibrous tissue (the splenic capsule) that supports its blood vessels and lymphatic vessels. The spleen is made up of two basic types of tissue, each with different functions: White pulp Red pulp The white pulp is part of the infection-fighting (immune) system. It produces white blood cells called lymphocytes, which in turn produce antibodies (specialized proteins that protect against invasion by foreign substances). The red pulp filters the blood, removing unwanted material. The red pulp contains other white blood cells called phagocytes that ingest microorganisms, such as bacteria, fungi, and viruses. It also monitors red blood cells, destroying those that are abnormal or too old or damaged to function properly. In addition, the red pulp serves as a reservoir for different elements of the blood, especially white blood cells and platelets (cell-like particles involved in clotting). However, releasing these elements is a minor function of the red pulp.

Controlled studies on treatment of catscratch disease (CSD) are lacking. Thus, treatment recommendations are based on case reports, reviews, a single controlled trial, and anecdotal data. Practice guidelines for the diagnosis and management of skin and soft-tissue infections, including CSD, have been established.Oct 19, 2016

A "Hallux Valgus" or "Hallux Abducto-Valgus" deformity, is commonly referred to as a "Bunion." This describes a pathological condition involving the position of the "hallux" in relation to the first metatarsal.

A bunion deformity can clinically present with a variety of characteristics. The foot itself may present with a wide splaying of the forefoot and a painful bump on the medial aspect of the first metatarsal phalangeal joint. In addition, the hallux may be abducted from the midline of the body, with a valgus rotation in the frontal plane.

A radiographic analysis of a bunion deformity in the Anterior/Posterior or Dorsal/Plantar view will reveal a variety of pathological components. Most notably so, is the exaggerated inter-metatarsal angle between the first and second metatarsal. This may be accompanied by a displacement of the first metatarsal from its position over the sesamoids, such that the metatarsal demonstrates a medial alignment away from the sesamoids which lie to the lateral side.

In some cases, the proximal articular set angle at the head of the first metatarsal may be off-set. This "PASA" is one of the factors which determines the position of the proximal phalanx on the metatarsal during movement as well as at rest.

Although conservative care may involve shoe modifications, padding, strapping, and custom orthosis; surgical reconstruction may be required to alleviate painful and immobilizing bunion conditions.

Soft tissue components of the bunion deformity are primarily addressed by means of a capsular modification, as well as a tenotomy of the adductor tendon at its insertion on the base of the proximal phalanx. The fibular sesamoid may be repositioned by a release of the surrounding ligaments.

Surgical management of the bone or osseous components of a bunion deformity will commonly include an osteotomy and correction to re-establish a more functional position of the first metatarsal within the forefoot. This capital fragment of bone is held in place with hardware fixation in order to secure a proper alignment during the healing phase, thus allowing the hallux to return to a more functionally useful position in the sagittal plane.
