Neuropathic pain: often difficult to treat. Palmitoylethanolamide (PEA) is a very special molecule, produced in our own body, against pain and chronic inflammation. PEA is available as supplement and as cream, and as dietfood for medical purposes in Italy and Spain. It has been explored since 1957 and has a clear analgesic and anti-inflammatory efficacy, and virtually no side effects. Meanwhile within the context of clinical trials 5000 patients have been using PEA, and its efficacy and safety has been documented in more than 400 scientific papers: http://palmitoylethanolamide4pain.com/about-2/ a website containing 400+ scientific articles on PEA in 6 different languages.

Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves and their echoes. The technique is similar to the echolocation used by bats, whales and dolphins, as well as SONAR used by submarines. In ultrasound, the following events happen: The ultrasound machine transmits high-frequency (1 to 5 megahertz) sound pulses into your body using a probe. The sound waves travel into your body and hit a boundary between tissues (e.g. between fluid and soft tissue, soft tissue and bone). Some of the sound waves get reflected back to the probe, while some travel on further until they reach another boundary and get reflected. The reflected waves are picked up by the probe and relayed to the machine. The machine calculates the distance from the probe to the tissue or organ (boundaries) using the speed of sound in tissue (5,005 ft/s or1,540 m/s) and the time of the each echo's return (usually on the order of millionths of a second). The machine displays the distances and intensities of the echoes on the screen, forming a two dimensional image like the one shown below.
En Bloc Esophageal Mucosectomy, an experimental technique for the endolumenal management of Barrett's related dysplasia and neoplasia. High grade dysplasia is in indication for esophagectomy; however esophagectomy has a mortality rate up to 12 percent, and up to 56 percent of patients may develop s...erious post-operative complications. Multiple ablated lesions can progress under the neo-squamous layer, leading to buried Barrett's mucosa. With conventional piecemeal EMR, cautery effect limits evaluation in areas of interest, Barrett's epithelium is left behind, tissue is not evaluated in situ and invasive lesions may be missed due to incomplete sampling. A new technique, en bloc esophageal mucosectomy, or EEM, was developed. The technique begins with conventional EMR in the proximal esophagus to access the submucosal space. Conventional EMR is being performed here. The mucosa is resected using an electrothermal snare. The mucosal defect from the first EMR is seen here. EMR is then repeated on the opposing wall. Sequential EMR creates a complete concentric mucosal defect. In the following sequence the completely detached column of mucosa can be seen, bounded by submucosa and muscularis propria layers. Here in the stomach, the endoscope is retroflexed and is covered by a sleeve of esophageal mucosa which has been freed to the GE junction and inverted. This sequence demonstrates a double snare technique. This snare is alongside the endoscope. The snare has been passed through the working channel. The working channel snare is pulled back, and the snare alongside the scope is used to grasp the mucosal column. With tension on the column the working channel snare can be threatened and advanced. This sequence shows the snare as it is being passed down to the GE junction. At the GE junction, the snare is tightened and cautery is applied. This frees the column of mucosal tissue from the remaining attachment. The endoscope is then withdrawn. Then detached mucosal column can be grasped with a snare and retrieved. In the following sequence, the long column of mucosa is being withdrawn via the overtube. Here, endoscopic forceps have been passed through the column to demonstrates the concentric nature of the specimen. The length of mucosa can be seen here alongside 2 conventional EMR specimens. Approximately 15cm of tissues was removed in this case. On endoscopy immediately following the resection, there is no bleeding or evidence of perforation in the area of resection. The endoscope is advanced and the exposed submucosa can be appreciated down to the GE junction. This is the low power view of the histologic specimen generated by EEM. Metaplastic tissue adjacent to a dysplastic focus would be completely removed. With a high power view, the layers of the esophagus can be appreciated. The epithelium, lamina propria, muscularis mucosa and submucosa are visible, with no cautery artifact in the area of interest. The technique would remove metplasia, low grade dysplasia, high grade dysplasia, and intramucosal carcinoma, as well a T 1 a lesions. All the animals in this series tolerated the procedure well. A total of five non-survival procedures and 4 survival procedures were performed. In the survival procedures, all four swine thrived in the post-operative period. Two swine were then survived for 9 days following the procedure. On post —op day nine, after passing into the upper esophagus, the proximal margin of the mucosectomy is seen here. Healing appears to be occurring. There is no evidence of leak, and no stricting is seen at 9 days down to the GE junction Passing into the stomach, some residual feed can be seen. Two swine were then survived for 13 days. On this follow-up endoscopy, the area of the mucosectomy is again healing. There was a loose stricture in both animals and both were easily traversed with a 9.8 mm gastroscope. There was a gross appearance of re-epitheliazation in some areas. It is notable that the stricture was present in the proximal esophagus with no narrowing distally. At necropsy there was not eviden
Shingles is a painful skin rash camera.gif. It is caused by the varicella zoster virus. Shingles usually appears in a band, a strip, or a small area on one side of the face or body. It is also called herpes zoster. Shingles is most common in older adults and people who have weak immune systems because of stress, injury, certain medicines, or other reasons. Most people who get shingles will get better and will not get it again. But it is possible to get shingles more than once.
A central venous catheter (CVC), also known as a central line, central venous line, or central venous access catheter, is a catheter placed into a large vein. Catheters can be placed in veins in the neck (internal jugular vein), chest (subclavian vein or axillary vein), groin (femoral vein), or through veins in the arms (also known as a PICC line, or peripherally inserted central catheters). It is used to administer medication or fluids that are unable to be taken by mouth or would harm a smaller peripheral vein, obtain blood tests (specifically the "central venous oxygen saturation"), and measure central venous pressure.
Scleral fixated IOLs in case of inadequacy of capsular support and scleral sutured capsular tension rings when adequate zonular support is inavailable have been recently used in cataract surgery. In these techniques, polypropylene suture is used and the suture ends over the sclera after the knot ha...s been formed, may erode the conjunctiva and become exposed. Thus, the erosion may lead to the development of endophtalmitis. In order to prevent the aforementioned complication, scleral flaps, otologous cornea, duramater or fascia lata patches have been used to cover the knot and rotation of the knot into the tissues has been described.
A ganglion cyst is a tumor or swelling on top of a joint or the covering of a tendon (tissue that connects muscle to bone). It looks like a sac of liquid (cyst). Inside the cyst is a thick, sticky, clear, colorless, jellylike material. Depending on the size, cysts may feel firm or spongy.

What is idiopathic intracranial hypertension??? Idiopathic intracranial hypertension (IIH) is a disorder that results from an increase in the pressure of the Cerebro-Spinal Fluid (CSF) that cushions and protects the brain and spinal cord. The CSF is constantly produced in the brain and reabsorbed back into the bloodstream at a fairly constant rate. This allows the fluid pressure around the brain to remain constant. What are the symptoms of idiopathic intracranial hypertension? Headaches that are generally nonspecific in location, type and frequency and can be associated with nausea and vomiting. Pulsatile tinnitus is a rhythmic or pulsating ringing heard in one or both ears. Horizontal double vision can be a sign of pressure on the 6th cranial nerve(s). Nonspecific radiating pain in the arms or legs (radicular pain). Transient obscurations of vision (TOV), which are temporary dimming or complete blacking out of vision. Visual field defects. These defects can occur in the central as well as the peripheral vision. Loss of color vision. What causes idiopathic intracranial hypertension? The cause is usually not known. A common explanation for increased pressure is a problem with the reabsorption of this fluid back into the body, which causes the pressure to increase. Sometimes the cause is determined and is referred to as “secondary” intracranial hypertension.
Gunshot wounds have become increasing common in urban cities and many such cases can lead to undesirable outcomes. While gunshot wounds to the head are considered most lethal, gunshot wounds to the chest too may be dangerous. Gunshot wound to the chest is challenging owing to the presence of vital organs like lungs, heart and their surrounding structures including major blood vessels. Gunshot wound is caused by penetration of the bullet, which travels through a projectile path after being shot from a firearm. The bullet, on hitting the chest, punctures the tissue it first encounters with, the bones or the muscular chest wall. The extent and severity of the injury depends on the characteristics of the bullet and the firearm, the position and the distance of the victim, the projectile path and the nature of the tissue penetrated.
An esophageal stent is a flexible mesh tube, approximately 2cm (3/4 inch) wide, and is placed through the constricted area of your esophagus (food tube) to allow food and beverages to pass from your mouth to your stomach for digestion and absorption of nutrients.
Diabetes, often referred to by doctors as diabetes mellitus, describes a group of metabolic diseases in which the person has high blood glucose (blood sugar), either because insulin production is inadequate, or because the body's cells do not respond properly to insulin, or both. Patients with high blood sugar will typically experience polyuria (frequent urination), they will become increasingly thirsty (polydipsia) and hungry (polyphagia).
Extracorporeal shock wave lithotripsy (ESWL) uses shock waves to break a kidney stone into small pieces that can more easily travel through the urinary tract camera.gif and pass from the body. See a picture of ESWL camera.gif. You lie on a water-filled cushion, and the surgeon uses X-rays or ultrasound tests to precisely locate the stone. High-energy sound waves pass through your body without injuring it and break the stone into small pieces. These small pieces move through the urinary tract and out of the body more easily than a large stone. The process takes about an hour. You may receive sedatives or local anesthesia. Your surgeon may use a stent if you have a large stone. A stent is a small, short tube of flexible plastic mesh that holds the ureter open. This helps the small stone pieces to pass without blocking the ureter.
The foods for your child are easily digestible foods, such as rice cereal, pasta, breads, cooked beans, mashed potatoes, cooked carrots, applesauce, and bananas. Pretzels or salty crackers can help your child replace the salt lost from diarrhea. Foods containing large amounts of sugar or fat should be avoided.
Niemann-Pick disease is a condition that affects many body systems. It has a wide range of symptoms that vary in severity. Niemann-Pick disease is divided into four main types: type A, type B, type C1, and type C2. These types are classified on the basis of genetic cause and the signs and symptoms of the condition. Infants with Niemann-Pick disease type A usually develop an enlarged liver and spleen (hepatosplenomegaly) by age 3 months and fail to gain weight and grow at the expected rate (failure to thrive). The affected children develop normally until around age 1 year when they experience a progressive loss of mental abilities and movement (psychomotor regression). Children with Niemann-Pick disease type A also develop widespread lung damage (interstitial lung disease) that can cause recurrent lung infections and eventually lead to respiratory failure. All affected children have an eye abnormality called a cherry-red spot, which can be identified with an eye examination. Children with Niemann-Pick disease type A generally do not survive past early childhood.
