Dermoid cysts develop from sequestration of epithelium along lines of embryonic fusion.The most common locations are the lateral third of the eyebrows, nose, and scalp. These cysts are located in the subcutis; they are often adherent to periosteum, and may invade or erode underlying bane. A 34-year-old female presented with a solitary, skin colored, dome-shaped, child fistsized, subcutaneous mass on her right occiput. At operation, keratinous material was discharged and tufts of hair projected from opening of the cyst wall.The base of the cyst was firmly adherent to periosteum and diffuse depression with focal deep erosions of the outer table of skull was found.

BACKGROUND: Acutely induced hypoxia causes an increase in the mean arterial pressure, cardiac output and oxygen consumption. However, comparisons of hemodynamic changes and oxygen consumption between subjects with and without anesthesia are rare. The purpose of this study was to examine and compare the hemodynamic changes and oxygen availability after acute apnea between the dogs with and without anesthesia. METHODS: Apnea was induced to 19 healthy mongrel dogs. Group 1 (N=10) constituted dogs with anesthesia and group 2 (N=9) constituted dogs without anesthesia. Hemodynamic data and oxygen levels were rapidly measured with 1 minute intervals. RESULTS: The survival time of group 1 was longer than that of group 2. The mean arterial pressure increased in group 1. Although the cardiac outputs in both groups increased at the same time course in early phase of apnea, the preload values increased more rapidly in group 1. Systemic vascular resistance decreased at 2 and 3 minutes of apnea in group 1 but not in group 2. The oxygen extraction ratio increased significantly at 4 and 5 minutes of apnea in group 2. CONCLUSION: In this study the dogs with anesthesia had a prolonged survival time compared to the dogs without anesthesia. Most hemodynamic values did not differ significantly between the two groups, except for an increased mean arterial pressure and decreased systemic vascular resistance in the dogs with anesthesia. It was suggested that the cause of early death in the dogs without anesthesia was decreased oxygen delivery.

In general the appearance of cerebrospinal fluid (CSF) is the most important sign of adequate dura puncture. We experienced an unusual case of spinal failure due to the blockage of a spinal needle hole by a foreign body. After the needle tip penetrated the dura, the stylet was removed, but we could not see a free flow of CSF. We found that a small rubber fragment of the local anesthetic bottle plug was on the spinal needle tip. The reason for this was the aspiration of the local anesthetic with an 18 gauge introductory needle.

This study was undertaken for the clinical analysis and evaluation on 121 patients with incompetent internal os of the cervix, who were admitted and treated with McDonald operation or Shirodkar operation at the Soonchounhyang Medical Center from January 1991 to December 1995. The results of this study were as follows : 1. The incidence of this IIOC was 1.1% of 11,116 cases of total delivery. 2. The mean age of IIOC was 31.7 years old. 3. The average number of gravida was 3.2. 4. The most common contributary factor was previous history of artificial abortion (51.2 %), and midtrimester abortion (17.4 %), cervical laceration due to previous vaginal delivery (8.3 %) etc. was followed. 5. The success rate of operation was 76 %, and the highest success rate (85.7 %) was reveald with period from 15th weeks to 16th weeks of gestation. 6. When cervical dilatation was abscent or small, the success rate of operation was high. 7. The factors of failed operation were preterm labor (58.7 %), PROM (34.5 %), and PIH, bleeding. 8. The delivery method after operation was vaginal delivery in 83 cases (68.6%) and cesarean section in 38 cases (31.4 %).
