OBJECTIVE: The purpose of this study is to measure plantar foot pressure and to make comparison of plantar foot pressure between measurements with and without ballet shoes. METHOD: Sixty six feet of healthy ballerinas were evaluated by Footscan plate and Foot scan Pro 4.5 program to analyze plantar foot pressure. We measured plantar foot pressure with and without ballet shoes respectively. The foot was divided into 7 different points on the basis of each metatarsal bone head, 1st toe, and heel. Also total plantar foot pressure was measured. RESULTS: There were no difference in plantar foot pressure between with and without ballet shoes. The highest pressure point of plantar foot in all subjects is the heel with ballet shoes and the great toe without ballet shoes. And the highest pressure point of plantar foot in skilled ballerinas is the great toe with and without ballet shoes. Also the highest pressure point of plantar foot in unskilled ballerinas is the heel with ballet shoes and the second metatarsal head without ballet shoes. CONCLUSION: We concluded that the ballerinas may need the protective ballet shoes.

A rare primary segmental omental infarction in an adult. Infarction of a part of the greater omentum has been recognized as an uncommon condition that may mimic other acute abdominal conditions, particularly acute appendicitis and acute cholecystitis. The presentation and course are seldom typical of appendicitis or cholecystitis. A greater omental infarction may occur without a recognizable cause, and may be termed "primary" (idiopathic), but in some cases, a cause is discovered, such as; mechanical interference with the blood supply to the omentum secondary to torsion, or systemic disorders such as cardiac, vascular, and hematological disease. The inflammatory necrotic mass resulting from the infarction produces somatic pain at its location in the abdomen. For unknown reasons the infarction occurs most commonly in the right half of the abdomen, especially the lower quadrant. An sign of peritoneal irritation, tenderness, and muscle guarding are the principal findings elicited on palpitation of the abdomen. Occasionally, a point of exquisite tenderness may be detected; this usually corresponds to the site of the infarction. Recognizing the typical imaging featuresan ovoid or cake-like mass in the omental fat with surrouding inflammatory changesof this condition is important, as most cases can be managed without surgery. We report a case of an adult patient with acute abdominal pain who was diagnosed with a right-sided segmental omental infarction.

Bezoars are concretions of foreign bodies found in the gastrointestinal tract. In the past, most common method for the treatment of bezoar was surgical management. However, the current treatment methods include chemical dissolution and endoscopic mechanical lithotripsy. There were few reports on the treatment of phytobezoars by nasogastric Cola lavage. However, there was no report succeeded by oral route alone. In our two cases, phytobezoars were treated by oral administration of Coca-Cola. Our patients drank 700-800 mL of Coca-Cola daily, and after two months, complete dissolutions of bezoars were achieved. We report two cases of phytobezoars completely treated by drinking Coca-Cola.
