Dislocation of peroneal tendons are caused by forceful domifiexion of the foot accompanied by a powerful contraction of the peroneal muscles. This mechanism of injury tears the superior pemneal retinaculum and allows the tendons to snap anteriorly. It is an important, although infrequent, cause of disability of the ankle. The acute injury can be treated by immobilization in a plaster cast, but when there is chronic recurring dislocation, surgical reconstruction is necessary. Authors experienced two cases of dislocation of pemneal tendons which were treated by use of Sarmiento's and Platzgummer's(modified) operative procedures with good results.

Ossification of the ligamentum flavum(OLF) is a well recognized cause of acquired spinal canal stenosis resulting in myelopathy, radiculopathy, or a combination of both. OLF is extremely rare in caucasian patients, but is one of the most common causes of compression of the posterior thoracic spinal cord in Japan. In most cases, it has been found in the thoracolumbar regions, and rarely in the cervical region. It is frequently but not alwalys found in association with ossification of the posterior longitudinal ligament(OPLL) and may cause cumulative damage, if comhined with OPLL. We experienced a case of ossification of the ligamentum flavum and posterior longitudinal ligament with sacral radiculopathy, which was treated hy posterior decompressive laminectomy and removal of the ossified ligamentum flavum and posterior longitudinal ligament. The day after operation, the radiating pain and paresthesia dramatically improved.

A rare case of traumatic bilateral anterior and posterior dislocstions of the hip wss occured by autamobile accident as a passenger injury. The right hip was dislocated anteroinferior to the righ scetabulum(neer the right obturator froamen), and the left hip was dislocated posterosuperior to the left acetsbulum with a ipsilateral femur head fracture caudsd to the fovea centralis(Fig. 1).

During The last 11 years from Jan. 1980 to Dec. 1990, 72 cases of salmonellosis has been admitted to the Department of Pediatrics of National Medical Center and evaluated clinical difference between typhoid fever and salmonella gastroenteritis. The results were as follows: 1) The annual incidence of salmonella gastroenteritis insalmonellosis was increased in the latter half of the eighties. 2) Both salmonellosis had its peak incidence in the summer. 3) Salmonella gastroenteritis was highest in the age of less than 5 year in contrast with the age of 6~9 year in typhoid fever. 4) The specimens isolated salmonellae were blood and stool in most cases, especially blood in typhoid fever and stool in gastroenteritis. 5) S.typhi was 16 cases, salmonella group A was 3 cases, group B was 16 cases and Group D and E were a case in each in isolated salmonellae. 6) On the antibiotic sensitivity test, S.typhi was sensitive to the most antibiotics. but the salmonella group B was relatively resisitant to Ampicillin, Carbenicillin, Tetracycline and Chloramphenicol.

The authors experienced a case of congenital dermoid cyst. It originated from the orbit, bulbar conjuntiva of both eyes and upper-lid of the left eye. This 6 years-old boy has a history of a progressively enlarging mass on both lateral canthus, bulbar conjunctiva and upper-lid of the left eye without pain and discomfort since birth. At the time of his first visit to our hospital, the lesion was 3 X 3 X 1.5cm (left eye) and 1.5 X 1.5 X 1cm (right eye) in size, yellowish-brown in color, firm and breast-like in shape. The vision was peor (right 0.1, left H.M.), the extraocular muscle motion was slightly limited. The roentgenographic and laboratory studies were in the normal limits. The surgical removal of the lesion was successfully performed under general anesthesia. The histopathological study revealed a dermoid cyst. After discharge, the patient was followed-up for 30 days. On lhe 15th postoperative day, epithelization was found. We found no evidence of further new growth.

PURPOSE: Foreign bodies in the airway of infant and children require prompt diagnosis and removal. To evaluate the pattern of clinical characteristics and disease course, we reviewed and analyzed a 6-year experience with pediatric airway foreign bodies in children. METHODS: We retrospectively reviewed the medical records of pediatric foreign body aspiration managed by pediatric and otorhinolaryngologic departments of Ajou University Hospital from November 1994 to October 2000. Nineteen cases of aspiration were collected and we analyzed their age, sex, symptoms, duration between onset of symptoms and diagnosis, initial simple radiographic findings, matierials of aspirations, anatomic location of foreign body, length of hospital day, and complications. RESULTS: The mean age was 2.7 years and male-to-female ratio of 1.8 : 1. In 11 cases, choking episode was identified by parents or patients. The correct diagnosis was made within first 24 hours of aspiration in 4 patients; while in 15 cases, the proper diagnosis was done after 24 hours. The most common presenting symptoms were cough (73.6%) and decreased breath sounds (57.9%) and the most common initial finding of simple radiographs was emphysema, presented in 68.4% of patients. Vegetable substances, particularly peanuts were the most common material of identified foreign body. Nine foreign bodies were in the right bronchus, 8 in the left bronchus and 2 in the subglottic area. The mean duration of admissions were 3.75 days in pateints who were diagnosed within 24 hours, however, 8.61 days in those with a delayed diagnosis (P=0.012). CONCLUSION: Taken together, the majority of accidental foreign body aspiration in airway was found under 3-year of age. Pediatricians and parents should be conscious to check for history of foreign body aspiration who have suspicious clinical features of aspiration, for early diagnosis and proper management without complications and long term morbidity.
