Bone healing can be divided into four stages: inflammation; soft callus formation; hard callus formation; remodeling.

On Tuesday May 29th at 3:00pm EDT, University Hospitals Case Medical Center Cleveland, Ohio, will host a live webcast to demonstrate the removal of brain tumor and epileptic focus from an awake patient using intra-operative MRI and brain mapping. See this on OR-Live.com

The patient was a middle-aged gentleman with new onset seizures. An MRI showed what appeared to be a low grade glioma near the motor strip on the right. Studies have shown that complete removal can cure the seizures, improve quality of life and survival, but this is difficult to do with conventional technology without harming the surrounding normal brain because its difficult to determine where tumor ends and normal brain begins.

At each level of the spine, there is a disc space in the front and paired facet joints in the back. Working together, these structures define a motion segment (Fig. 1A). Back pain may re­sult when injury or degenerative changes allow abnormal movement of the vertebrae to rub against one another, known as an unstable motion segment (Fig. 1B). Two vertebrae need to be fused to stop the motion at one segment. For example, an L4-L5 fusion is a one-level spinal fusion (Fig. 1C). A two-level fusion joins three vertebrae together and so on.

The menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible. The cycle is required for the production of oocytes, and for the preparation of the uterus for pregnancy.

An MRCP scan is a scan that uses magnetic resonance imaging (MRI) to produce pictures of the liver, bile ducts, gallbladder and pancreas. Note: the information below is a general guide only. The arrangements,and the way tests are performed, may vary between different hospitals.

The term chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) has been used to identify patients with a chronically progressive or relapsing symmetric sensorimotor disorder with cytoalbuminologic dissociation and interstitial and perivascular endoneurial infiltration by lymphocytes and macrophages. It can be considered the chronic equivalent of acute inflammatory demyelinating polyradiculoneuropathy, the most common form of Guillain-Barré syndrome. Signs and symptoms CIDP typically starts insidiously and evolves slowly, in either a slowly progressive or a relapsing manner, with partial or complete recovery between recurrences; periods of worsening and improvement usually last weeks or months. Most experts consider the necessary duration of symptoms to be greater than 8 weeks for the diagnosis of CIDP to be made. Symptoms reported include the following: Preceding infection (infrequent) Initial limb weakness, both proximal and distal Sensory symptoms (eg, tingling and numbness of hands and feet) Motor symptoms (usually predominant) In about 16% of patients, a relatively acute or subacute onset of symptoms In children, usually a more precipitous onset of symptoms Symptoms of autonomic system dysfunction (eg, orthostatic dizziness) Pertinent physical findings are limited to the nervous system, except when the condition is associated with other diseases. Such findings may include the following. Signs of cranial nerve (CN) involvement (eg, facial muscle paralysis or diplopia) Gait abnormalities Motor deficits (eg, symmetric weakness of both proximal and distal muscles in upper and lower extremities) Diminished or absent deep tendon reflexes Sensory deficits (typically in stocking-glove distribution) Impaired coordination See Clinical Presentation for more detail. Diagnosis Laboratory studies that may be helpful include the following: Cerebrospinal fluid analysis: Elevated protein levels are common (80% of patients); 10% of patients also have mild lymphocytic pleocytosis and increased gamma globulin Complete blood count (CBC), erythrocyte sedimentation rate (ESR), antinuclear antibody (ANA) level, biochemistry profile, and serum and urine immunoelectrophoresis (to exclude associated systemic disorders) In certain instances, genetic testing Other tests and procedures that may be warranted are as follows: MRI of the spine with gadolinium enhancement Electromyography (EMG) is a critical test to determine whether the disorder is truly a peripheral neuropathy and whether the neuropathy is demyelinating Peripheral (sural) nerve biopsy (see the image below): This is considered when the diagnosis is not completely clear, when other causes cannot be excluded, or when profound axonal involvement is observed on EMG; biopsy was once commonly recommended for most patients before immunosuppressive therapy, but current guidelines no longer recommend it

Cardiac surgeons Faisal Baaeen, MD and Edward Soltesz, MD talk about coronary artery bypass graft (CABG) surgery in this informative video.

They describe:
• how blockages are bypassed
• how vessels are used for the bypass graft
• reoperation experiences
• the importance of complete revascularization
• and options such as off pump bypass surgery and minimally invasive surgery

External cephalic version, or version, is a procedure used to turn a fetus from a breech position or side-lying (transverse) position into a head-down (vertex) position before labor begins. When successful, version makes it possible for you to try a vaginal birth.

A decade ago we thought that Chikungunya was a tropical disease restricted to the rain forests. However, after the 2007 epidemic in Italy and later in the Reunion islands, this dreaded condition has now spread to the Carribean and the Americas. Its an arthropod borne alpha virus which causes fever, polyarthralgia and arthritis. There could be serious complications in the adult such as meningoencephalitis or GBS as well as in neonates. This presentation discusses in detail the clinical features, diagnosis and management of Chikungunya fever. A detailed discussion of its complications is also included. Check out our other videos

Bell's palsy is a form of facial paralysis resulting from damage or trauma to the facial nerves. The facial nerve-also called the 7th cranial nerve-travels through a narrow, bony canal (called the Fallopian canal) in the skull, beneath the ear, to the muscles on each side of the face. For most of its journey, the nerve is encased in this bony shell. Each facial nerve directs the muscles on one side of the face, including those that control eye blinking and closing, and facial expressions such as smiling and frowning. Additionally, the facial nerve carries nerve impulses to the lacrimal or tear glands, the saliva glands, and the muscles of a small bone in the middle of the ear called the stapes. The facial nerve also transmits taste sensations from the tongue. When Bell's palsy occurs, the function of the facial nerve is disrupted, causing an interruption in the messages the brain sends to the facial muscles. This interruption results in facial weakness or paralysis. Bell's palsy is named for Sir Charles Bell, a 19th century Scottish surgeon who described the facial nerve and its connection to the condition. The disorder, which is not related to stroke, is the most common cause of facial paralysis. Generally, Bell's palsy affects only one of the paired facial nerves and one side of the face, however, in rare cases, it can affect both sides.

(cryptorchidism) is a testicle that hasn't moved into its proper position in the bag of skin hanging below the penis (scrotum) before birth. Usually just one testicle is affected, but about 10 percent of the time both testicles are undescended. An undescended testicle is uncommon in general, but common among baby boys born prematurely. The vast majority of the time, the undescended testicle moves into the proper position on its own, within the first few months of life. If your son has an undescended testicle that doesn't correct itself, surgery can relocate the testicle into the scrotum.

Addison's disease is a disorder that occurs when your body produces insufficient amounts of certain hormones produced by your adrenal glands. In Addison's disease, your adrenal glands produce too little cortisol and often insufficient levels of aldosterone as well. Also called adrenal insufficiency, Addison's disease occurs in all age groups and affects both sexes. Addison's disease can be life-threatening. Treatment for Addison's disease involves taking hormones to replace the insufficient amounts being made by your adrenal glands, in order to mimic the beneficial effects produced by your naturally made hormones.

-Traumatic amputation of a body part requires rapid transport of the appendage, which should be wrapped in a saline-moistened gauze, placed in a plastic bag, and transported in a container filled with ice mixed with either saline or sterile water to best preserve the body part and attempt replantation.
