Osteochondroma is the most common of the benign bone tumors. They are probably developmental malformations rather than true neoplasms. But rarely they develope in a joint, especially in the ankle joint. We reported a case of intraarticular osteochondromatosis of ankle joint.

The giant intra-articular osteochondroma of the knee is very rare and is probably result of synovial metaplasia of the fibrous capsule or of the adjacent connencive tissue of a joint, and of the fragment of articular cartilage. The gross findings and histology are consistent with the osteochondroma. The authors experienced a case of giant intra-articular osteochondroma of the right knee in a 19 years old man who had history of knee injury when he was 16 years old. The mass was excised and the symptome was relieved.

A simple, rapid and selective liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) is developed and validated for quantification of venlafaxine in human plasma with simple liquid-liquid extraction step consisted of extraction with ether and dichloromethane for 10 min and mixing with 1 M sodium acetate in human plasma using fluoxetine as an internal standard (IS). The analyte are separated using an isocratic mobile phase consisted of acetonitrile and 5 mM ammonium formate (4/3, v/v) on a isocratic YMC hydrosphere C18 (2.0x50.0 mm, 3.0 microm) column and analyzed by MS/MS in the multiple reaction monitoring (MRM) mode using the transitions of respective [M+H](+) ions, m/z 278.2-->260.3 and m/z 310.1-->148.1 for quantification of venlafaxine and IS, respectively. The standard calibration curves showed good linearity within the range of 1.0-200.0 ng/mL (r2=0.9986, 1/chi2 weighting). The lower limit of quantification (LLOQ) was 1.0 ng/mL. The retention times of venlafaxine and IS were 0.6 min and 0.7 min that means the potential for the high-throughput potential of the proposed method. In addition, no significant metabolic compounds were found to interfere with the analysis. Acceptable precision and accuracy were obtained for the concentrations over the standard curve range. The validated method was successfully applied to bioequivalence study after 75-mg of venlafaxine sustained-release (SR) capsule in 24 healthy Korean subjects.

A patient with corneoscleral dermoid was suspected of having allergic contact dermatitis and conjuntivitisdue to Pontocaine. She was tested with standard European patch test including other suspected medicaments used in the preparation of eye drops. The patient showed + + positive patch test reaction to pontocaine, caine mixture and benzocaine under 2 day and 4 day patch test reading. The importance of routine patch test in ophthalmic patients whenever contact conjuntivitis is suspected is stressed.

OBJECTIVE: We analyzed the clinical features of amniotic fluid embolism confirmed by autopsy or clinical dicision for making a plan of rapid diagnosis and intensive emergency care. STUDY DESIGN: We experienced 2 clincal cases in Ewha Mokdong Hospital and Severance Hospital at 1995, and reviewed the medical record & autopsy report of 15 cases in National Institute of Scientific Investigation from Jan, 1991 to Dec, 1995. RESULTS: The mean maternal age was 31+/-3 years. The mean gestational age was 40+/-1 weeks. The number of delivery were 1.4+/-0.8. The number of abortion history. were 2.6+/-2. The sexuality of fetus were six males (35 %), five females (29%), and unknown six cases (35 %) and the fetal mortality rate was 29 % (5 cases). The initial clinical symptoms and signs were hypotension (12 patients, 71%), vaginal bleeding(ll patients, 65%), cardiac arrest (6 patients, 35 %), dyspnea (5 patients, 29 %), and seizure (2 patients, 12%). In the case of normal spontaneous vaginal delivary (NSVD), the symptoms occurred during induction in 3 (18%), during delivery in 1 (6%), and after delivery in 9 (53%). In the case of Cesarean section, the symptoms occurred during section in 2 (12%), and after section in 1 (6%). There are one case whose symptoms occurred during 3rd gestational period. CONCLUSIONS: We should alert for the amniotic fluid embolism in the clinical findings of acute collapse and vaginal bleeding, respiratory symptoms, and seizure at any peripartum. With eary suspicion of this disease and aggressive intensive care we can reduce amniotic fluid embolism mortality rate and it's legal problem.

The Fracture of the os calcis is quite common in relation to fracture in other tarsal bone, and fractures involving the subtalar joint may cause serious and persistant disabilities. The treatment of these calcaneal fractures remains controversial So there is no universal agreement in the treatment of these fractures, especially involving the subtalar joint. Twenty displaced intraarticular fractures of calcaneus in 15 patients were treated by open reduction and internal fixation with a plate and screws and bone graft through a lateral approach to elevate the depressed lateral portion of the posterior facet at the Inchon Chritian Hospital from Jan., 1990 to Dec, 1991. Twenty feet in 15 patients of calcaneal fractures involving the subtalal joint were treated and were clinically analysed and following result were obtained. 1. The 20 cases were classified according to the Sanders classification, 9 in type II, 9 in type III and 2 in type IV. 2. The 20 cases were treated by open reduction andinteranl fixation with plate and screws and iliac bone graft through an Sanders lateral approach. The bone graft is packed under the elevated posterior to prevent late collapse of the central fragment and to supply structral stability. 3. The preoperative average Böhler's angle was 0.4°. The post operative average Böhler's angle was 23.4° which was increased significantly. 4. Based on assessment of result of Salama, excellenwas 6, good was 7, fair was 4 and poor was 3. 5. The most common complication after treatment was persistant pain, especially beneath the lateral malleolus.

To overcome the problems of classical pulmonary banding procedure, we developed a percutaneously adjustable pulmonary artery banding device. The banding device consists of banding portion of zig-zag shaped self-expandable stainless steel wire, shaft portion made by a polyvinyl catheter and a screw adjuster which includes a bolt and a nut. As the screw moves, the diameter of banding portion changes. Four Mongrel dogs ranging from 15 kg to 20 kg in weight underwent the banding of the mid portion of descending aorta with this devices through the left thoracotomy. One month after operation, we evaluated the pressure changes by controling the banding with the devices and then the dogs were sacrificed to study the microscopic changes in the aorta. The diameter and circumference of the band could be easily and finely adjustable by the screw control. The pressure recordings revealed a linear increase and decrease in pressure gradient according to percutaneous adjustment of the banding device. Since the banding device can be easily placed and simply adjusted percutaneously, we hope the banding device may be applicable clinically to improving the safety of pulmonary artery banding and debanding procedures in the future.
