In the classical ballet dancers, ankle joints are frequently overused. Especially the Pointe and the Releve are the two basic steps of ballet dance which cause the narrowing of the posterior aspect of the ankle joint. Posterior impingement syndrome of the ankle joint is defined as impingement occuring at the anatomical interval between the posterior tibial articular surface and os calcis. The purpose of this study is to describe the anatomy and etiology of this injury and to review the non-operative and operative treatments. Sixteen cases of posterior impingment syndrome had been treated between March 1994 and March 1995. Ten dancers were professional and six were students. The patients was divided 3groups by etiologic factor. Group 1 is anatomical problem factor, Group 2 is overuse factor and Group 3 is ankle sprain factor. Thirteen dancers (81.2%) improved with conservative treatment including local steroid injection. Among the other three dancers, operation was performed in one case. The other two cases stopped dancing. The result was good in one dancer after operation. In the classic ballet dancers, posrerior impingement syndrome was frequent disorder and major etiologic factors are anatomical problem and overuse. Operation was necessary in only group l. It is good result in conservative treatment and operation.

Flexor hallucis longus tendinitis is a common overuse syndrome in classic ballet dancers. To describe the clinical symptoms, diagnosis and non-operative and operative treatment, we evaluated twenty ballet dancers from march 1994 to August 1995. For the diagnosis, Tomasen test was helpful clinically and MRI was essential for surgical intervetion to find a tendon degeneration. Patients were classified into three groups by symptoms and clinical stages. All of the Group 1 and 2 were recovered by means of the conservative treatment. Two dancers belongs to Group 3 showed a severe degeneration of tendon on the MRI scan, finally was taken the an operation. Release of the tarsal tunnel were performed. Six months after operation, they could return to dancing.

BACKGROUND: Epidural steroids injections are often used for the treatment of low back pain but their effects on the endocrine system have not been determined. Few studies have quantified the degree or duration of the suppression of the hypothalamic-pituitary-adrenal (HPA) axis in humans given epidural triamcinolone injection (ETI) for low back pain. The evaluation of the blood adrenocorticotropic hormone (ACTH) and cortisol was undertaken to determine the extent of suppression of the HPA axis in patients given ETI. METHODS: Lumbar epidural triamcinolone injections were performed on the painful lumbar intervertebral space with patients in the lateral decubitus position. The injection consisted of 40 mg of triamcinolone acetonide diluted in 10 mL of 1% lidocaine. Patients remained in the lateral position for 10 min after the procedure. Basal blood sampling was performed at 30 min before ETI and tested blood sampling was obtained at 7 days, 10 days, and 14 days after ETI. RESULTS: The blood cortisol level was significantly decreased at 7 days and 10 days but at 14 days was not significantly decreased and the blood ACTH level was not significantly decreased at 7 days, 10 days, and 14 days. CONCLUSIONS: Above results demonstrate that blood ACTH and cortisol level normalize 7 days and 14 days, respectively, after epidural triamcinolone 40 mg injection.

Respiratory distress syndrome (RDS) of preterm infants remains a significant cause of morbidity and mortality despite improvements in neonatal intensive care and artificial ventilatory techniques. After identification of the deficiency of pulmonary surfactant is major pathophysiologic basis in RDS, artificial surfactant replacement therapy in RDS was first successfully tested by Fujiwara and co-workers in 1980. therefore, exogenous surfactant replacement produced exellent results in improved clinical and repiratory status during the acute period and decreased incidence of late complications and mortality. According to comparison of administration timing between early (within 6 hours after birth) and late (after 6 hours)group, early replacement therapy is more effective in improving of clinical course and prognosis. Because of that, early, just after birth, recognition and detection of RDS is also important procedure. There are many investigations and methods for the detection of RDS in prenatal or postnatal period. Among then, stable microbubble rating (SMR) test was a simple method and SMR test has a higher diagnostic accuracy. To determine the relation of the SMR and purified natural surfactant (PNS) concentration in vitro, the author conducted each 5 times test of SMR method according to 5 groups of PNS concentration by using modified Pattle's method. The results were as follows: 1) The mean and standard deviation of SMR according to 5 groups of PNS concentration were 119.4 (15.0in 20mug PL (phospholipid)/ml, 452.2 (160.2 in 40mug PL/ml, 879.0 (93.4 in 60mug PL/ml, 1311.8 (274.8in80mug PL/ml, 1710.6(272.3 in 100mug PL/ml. 2) The regression curve of SMR and PNS concentration showed statistically significant relation(p<0.005). In conclusion, the SMR test was a good method in estimation of surfactant concentration in vitro and also in diagnosis of RDS recognized as a surfactant deficiency. In the future, we expected that prophylactic surfactant replacement therapy. immediate after birth, will be more popular in the field of neonatal care of RDS. So, we recommended the use of this method for early detection and serving optimal care of RDS.
