Isolated avulsion fracture of the tibial attachment of the posterior cruciate ligament has been thought very rare. We also had experienced only nine cases of above injury in our center during 5.5 years from January, 1976 to June, 1981. Eight cases of them were followed for an average of the thirteen months, but one of them was eliminated from the study because follow-up study was impossible for the case. The purposes of this paper are to present eight cases of isolated avulsion fracture of the tibial attachment of the posterior cruciate ligament and to discuss the causes and mechanisms of the injury and the method of screw fixation for the avulsed fracture fragment. Seven were injured by traffic accident and one by fall on the knee. All cases seemed to be injured by the force directed against the flexed knee which violently stroke the anterior surface of the proximal end of the tibia or inferior portion of the knee and drove it backwards. We found the tear of posterior capsule only in one patient who was seeming injured by extensive force. All cases were treated operatively by means of screw fixation, and excellent results were obtained in five cases, good in two, and fair in one case.

We report three cases of rat mite dermatitis caused by Ornithonysus bacoti(Hirst, 1913), commonly referred to it as the tropicalrat mite. The first case, a 26-year old female had multiple pinhead sized vesicles with peripheral erythematous macule on the upper arms. The second case, a 34-year-old femal had multiple variable sized vesicles with erythematous base on the extremeties. The third case, a 43-year old male had multiple erythematous macules and papules with central punctum on the trunl: and extremities. Histopathologic sections from lesions of the first and second patient showed moderate perivascular lymphahistiocytic infiltration intermingled with some eosinophils. Causative mites, Ornithonyssus bacoti, female were collected around the skin lesion in rase 1, from the house dust in case 2 and furniture in case 3.

Subperiosteal Cortical Defect is a symptomless rarefaction of cortical bone which begins most often on the external surface of the medial and posterior cortical walls of the lower end of the femur in children between the ages of 3 and 6 years. The name of Subperiosteal Cortical Defect was first used by Aegerter who differentiated it from non-osteogenic fibroma. The authors found out 5 positive cases of incidental findings among 62 cases of both knee joint X-ray of which 3 was male and 2 was female. Also we experienced 3 cases which necessiat d a correct diagnosis and differential diagnosis. Because this is a common lesion, it frequently accompanies more serious bone conditions, and because this is self-limited disease, treatment is not necessary. It was emphasized that its nature should be understood by all those dealing with bone disease lest it be overdiagnosed and overtreated.

In certain low-grade malignant tumors such as chondrosarcoma and giant cell tumor, radical treatments may provide a good chance for cure. And large bony defect after the radical treatment can be filled with the massive bone graft. Recent advances in clinical microsurgery have made free tissue transfer a clinical reality, and Taylor in 1975, first reported the technique of free vascularized fibula graft for the reconstruction of large tibial defects with excellent clinical results. We tried wide excision and free vascularized bone graft in 6 patients with malignant or aggressive bone tumor from April 1981 to November 1985 and followed up for more one year. Mean follow up of free vascularized bone graft is 26.4 months and that of devascularized bone graft is 22.6 months. The results of the free vascularized bone graft were compared with 10 patients who were treated with the wide excision and the devascularized bone graft. In this analysis, free vascularized bone graft is superior to devascularized bone graft in bony union, complications and functional results.

Hepatolithiasis is common in east Asia, but rare in the Western world. Recently, epidemiologic study on Korea gallstone disease showed that the portion of patients with hepatolithiasis among total gallstone patients is 14.1%. Hepatolithiasis is the cause of recurrent cholangitis and it is that risk factor of liver abscess, hepatic failure, or sepsis. Also, biliary cirrhosis and cholangiocarcinoma were developed from hepatolithiasis. The incidence of cholangiocarcinoma associated with hepatolithiasis is about 2.4~10% . We present three cases of unresectable cholangiocarcinoma diagnosed after removal of hepatolithiases by percutaneous transhepatic cholangioscopy.

BACKGROUND: Laryngomicrosurgery has some special characteristics. It is stressful due to intubation and direct laryngoscopy during a short operation time. Therefore both adequate anesthesia and quick recovery for the slience therapy after the operation are needed. This study compared the cardiovascular responses and recovery pattern between propofol and Thiopental-Enflurane anesthesia. METHODS: Sixty outpatients of ASA class 1 or 2 for microlaryngoscopy were randomly assigned to receive either anesthesia with propofol (Group P, n = 30) and thiopental-enflurane (Group E, n = 30). Group P was induced with propofol 2 mg/kg and succinylcholine 1 mg/kg and maintained with vecuronium 0.04 mg/kg, propofol 10 - 6 mg/kg/h, and N2:O2/3 L/min:2 L/min. Group E was induced with thiopental 5 mg/kg and succinylcholine 1 mg/kg and maintained with vecuronium 0.04 mg/kg, enflurane 1 3 vol%, and N2O:O2/3 L/min:2 L/min. Ketorolac (30 mg) and hydrocortisone (100 mg) were added for postoperative pain in both groups. The changes in blood pressure and heart rate, pre and post induction, were compared in both groups. In addition, we compared energence time and the state of recovery (Steward's score) 5 minutes and 15 minutes after extubation and the frequencies of other complications. RESULTS: No significant differences in age, wt, sex and anesthesia time of the two groups were observed. Mean arterial pressures were significantly different after anesthesia and after intubation between the two groups. However the heart rates were not different among the groups. The extubation time was significantly shorter in Group P. The recovery score at 5 min and 15 min after extubation was significantly higher in Group P. CONCLUSIONS: We conclude that propofol with nitrous oxide may be useful in laryngeal microsurgery, especially, when silence therapy is needed.
