OBJECTIVE: To evaluate the relationship between amniotic fluid interleukin-8 and the presence, severity and pattern of acute inflammatory lesions in the placenta delivered after preterm labor with intact membranes. METHODS: The relationship between placental histologic finding and amniotic fluid interleukin-8 was examined in 46 consecutive patients who were admitted with the diagnosis of preterm labor with intact membranes and who delivered singleton gestations within 5 days. RESULTS: The prevalence of acute histologic chorioamnionitis was 63.0%(29/46) and that of positive amniotic fluid culture was 17.4%(8/46). The most frequent site of histologic inflammation was chorion-decidua(56.5%, 26/46). The median amniotic fluid interleukin-8 increased significantly according to the presence and higher severity of inflammation in each type of placental section (p<0.05 for each). Three patterns of inflammation were identified in chorion-decidua: non-marginating, marginating, and mixed. Median amniotic fluid interleukin-8 and the rate of severe histologic chorioamnionitis (grade> or = 4) increased significantly in the order of non-marginating, marginating, and mixed (p<0.05 for each). CONCLUSION: Both the presence and greater severity of acute histologic chorioamnionitis are associated with an elevated amniotic fluid interleukin-8. A marginating and mixed pattern of inflammation are associated with a higher amniotic fluid interleukin-8. Amniotic fluid interleukin-8 is a reliable prenatal marker of histologic chorioamnionitis.

We treated three cases of bone tumors-giant cell tumor, chondroblastoma and malignant fibrous histiocytoma-with a custom-made prosthetic replacement. The patients were followed from 10 months to 18 months, postoperatively. The results of these study are as follows: 1. Satisfactory anatomic restoration 2. Early ambulation 3. Good function 4. Biomechanically sound reconstruction

To observe the change in the status of stresses according to three different postural angulation of an intervertebral disc with or without nucleus pulposus, 6 specimens of a 3-dimensional photoelastic model of the spine were made of epoxy. The nucleus pulposus portion was replaced with silicon in three models, and the three were made without silicon. Through axial application of a vertical compressive load of 8 kg, the peculiar patterns of the isochromatic fringes were observed. Stresses on the intervertebral disc were analyzed according to three different postural angulations of the intervertebral disc with the nucleus pulposus and without the nucleus pulposus. The results of these study are as follow: 1. In an erect neutral posture with the nucleus pulposus, the stress concentration was much increased at the posterior portion rather than at the anterior portion. Also, the high stress was concentrated at the medial and central portion. In an erect neutral posture without the nucleus pulposus, the stress concentration was much increased at the anterior portion rather than at the posterior portion and the stress distribution seemed to be locally concentrated. 2. In a maximal flexed posture, the stress concentration was much increased at the posterior portion rather than at the anterior portion. Comparing the presence of the nucleus pulposus with the absence of the nucleus pulposus, the stress concentration was lower at the anterior portion in the presence of the nucleus pulposus than in the absence of the nucleus pulposus. However, the stress distribution at the posterior portion was nearly same in the two groups. According to the analysis of the stress distribution diagram, as a whole, the stress pattern around the disc was evenly distributed. 3. In a maximal extended posture, the higher concentration of the stress distribution at the anterior and medial portion rather than in the posterior and lateral portion was observed. The stress concentration was higher in the presence of the nucleus pulposus than in the absence of the nucleus pulposus. 4. Comparing the maximal flexed posture with the erect neutral posture, the stress concentration in the flexed posture was much decreased in the posterior portion rather than in the erect neutral posture, and an even distribution of the stress pattern in the flexed posture was observed. 5. In the presence of the nucleus pulposus, at the anterior and posterior portion, the stress concentration in the flexed posture was much decreased compared with the extended posture. In the absence of the nucleus pulposus, at the anterior and posterior portion, the stress concentration in the extended posture was much decreased compared with the flexed posture.

The incidence of contrast media extravasation has been increasing gradually. Most contrast media extravasations only can cause pain, swelling and erythema. However, in more severe cases, skin necrosis, ulceration, or compartment syndrome may occur, often necessitating a surgery. Early diagnosis and treatment should be established on the spot in order to avoid such a severe damage. We present a case of 42-year-old woman with a compartment syndrome in the right upper extremity caused by extravasation of computed tomography contrast media.
