On screening colonoscopy, this abnormality was encountered in the cecum. This round worm is Ascaris Lumbricoides, one of the most common human parasites in the world. When ingested, the durable Ascaris eggs hatch in the small intestine releasing larva that migrate through the intestinal wall, and t...ravel both hematogenously and lymphatically to the heart and lungs. Over the next several days, the larva mature in the alveoli, then migrate up the trachea to be swallowed back into the gastrointestinal tract. These larva will then mature in the small bowel; adults couples will succeed in producing an extraordinary number of eggs, over 200,000 ova per day. The adults live one to two years. The majority of Ascaris infections are as in this example asymptomatic. Symptoms are a consequence of either the immunologic hypersensitivity of the host to the worm as in the pulmonary stage referred as Loffler's syndrome or to mechanical obstruction of lumen by the worm. Heavy worm burden can result in intestinal obstruction and migrating worms can cause pancreatitis and/or cholangitis when involving the pancreatobiliary tree. Multiple medical therapies are approved for its treatment including mebendazole. Epidemiologically, infections are most common in areas of lower socio-economic conditions.

From an endoscopic standpoint it is noteworthy that the worms do not like light and will move away fro the attention it is receiving. In this example, the endoscopist was too slow to snare his prey which succeeded in escaping temporarily into the cooler and darker confines of the small bowel out of reach of the endoscope but not from the soon to be consumed anti-helminthic therapy.

This task requires streching a rubber band around 16 nails on a wooden board. A penalty is calculated when the rubber band is not streched around a nail at the end of the task. Score = time (seconds) + number of missed nails x 10. Performance standard: Score = 62 sec [Kolkman 2008]

A videos of cataract surgery

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.
