For many years, healing membranous bone fractures have been known to show a persistent lucency at the fracture interface. Radiographic follow-up has proven to be of little value as a guideline for healing of mandibular fractures. Recently, a fracture has been treated by rigid internal fixation by metallic plate and screws rather than closed reduction and wire fixation, we expected that some difference in the radiographic features of fracture healing. To investigate these questions we undertook a retrospective radiographic and clinical analysis of 33 followed patients with fractures of the body and angle of the mandible from 1993 to 1997. There were 26 male and 7 female patients ranging in age between 5 and 74 years, with an average of 29.7 years. All patients were managed by open reduction with metallic plates and screws. The length of follow-up ranged from 9 to 187 weeks. Total 81 radiographic follow-up films were obtained and divided into 3 grades according to the degree of radiolucency of fracture lines; grade 0 radiolucent fracture line and no evidence of fracture interface calcification, grade 1 decreased radiolucent area and evidence of fracture interface calcification, and grade 2 disappearance of fracture line.Until follow-up of 8 weeks, all of the radiographs showed grade 0. From 8 weeks to 16 weeks, 62.5 percent showed grade 0 and 37.5 percent showed grade 1. From 16 weeks to 48 weeks, 38.5 percent showed grade 1 and 61.5 percent showed grade 2. After follow-up of 48 weeks, all showed grade 2.In this study we have shown that the radiographic disappearance of mandibular fracture lines was usually accomplished by 48 weeks. We feel that radiographic union of the mandible is lagging well behind clinical union, but disapperance of the fracture line in rigidly fixated mandibular fracture was occurred earlier than healed by fibrous union. We propose that radiographic union of the mandible by approximately 1 year can be a guideline for the normal mandibular bone healing.

From January 1985, to June 1986, 7 cases in which supracondylar and intercondylar fractures of the femur were treated at our orthopaedic department using the Extensile Approach for an anatomical reduction and firm internal fixstion, show successful results in follow up stuides. l. All 7 cases were type III fractures of Neers classification. 2. Among the 7 cases treated surgically using the Extensile Approach, 5 cases showed excellent and good results and the remaining 2 csses showed one fair and one failed results. 3. Probably due to the additional open proximal tibia and patella fracture and delayed surgery from trauma one case had a fair results. The case which failed wss due to ipsilsteral ligamentous injuries and a nerve injury in addition to the femur fracture and slso the impossibility of early knee joint exercise due to associated injuries. 4. None of the results of the 7 csses had any relationship with the patients age. 5. One case of postoperative skin necrosis developed around the tibial tuberosity and was treated successfully by a cross leg flap. 6. In comminuted supracondylar and intercondylar fractures of the femur, the Extensile Approach is thought to be an excellent surgical technique by means of a wide surgical field for an anatomical reduction and firm internal fixation with the repair of associated ligamentous injuries.

Congenital pseudarthrosis of the tibia was accepted as one of the most difficult disease in respect of the frequency and treatment for the orthopaedists. Since April, 1984, we experienced 3 cases of congenital pseudarthrosis of the tibia, one 2 year-old boy involved left tibia only and the other 4 year-old female involved bilaterally, obtained solid bony union in all which were treated by massive surgical management that contained vascularized bone graft and electric stimulation. Several complications were faced such as refracture, valgus deformities of the ankle, skin irritation sign, angular deformities. But refracture was healed without delayed or nonunion by simple plaster cast immobilization. The vascularized bone graft snd electric stimulation is thought to be more improved methods for the treatment of congenital pseudarthrosis of the tibia. Althought solid bony union was obtained in congenital pseudarthrosis of the tibia, periodic follow-up and adequste management must be mandatory up to the end of the bony growth.

BACKGROUND: Intra-aortic balloon pump (IABP)is well known for its hemodynamic benefit but still has its own complications.Proper use of IABP is the best way t o obt ai n maximum benefit with low complication rate. MATERIALS AND METHOD: Twenty one(men 10,female 11) patients were included in this study among the 100 consecutive adult cardiac surgery patients in our hospital.Eighteen(85.7%)were ischemic heart disease patients.They all received IABP therapy due to postcardiotomy cardiogenic shock according to the well-known indications.Their preoperative conditions,intraoperative factors including hemodynamics, postoperative conditions and IABP-related complications were analyzed. RESULT: Nineteen patients(90.5%)were successfully weaned from IABP.There were 2 patients of operative death and the mortality rate was 9.5%.Duration of IABP use was 40.7+/-24.3 hours.There were 2 cases(9.5%)of IABP-related vascular complications that required surgical intervention. CONCLUSION: We concluded that IABP could be used effectively and safely for postcardiotomy cardiogenic shock patients with low complication rate.

Subcutaneous fat necrosis of the newborn is an uncommon disorder characterized by firm b-cutaneous plaques and nodules usually appearing shortly after birth. It runs a relatively be, n course and may completely resolve in a few months without any recurrence. We report a case of subcutaneous fat necrosis in a 15 day-old male suffering from severe p inatal asphyxia and hypoxic cardiomyopathy, who presented with indurated subcutane s nodules and plaques on the both shoulders and the back. Histologically the subcutaneous fat showed focal necrosis with needle-shaped clefts, lymphohistiocytic infiltration and foreign body reactions consistent with subcutaneous fat necrosis of the newborn. In our patient, compromised cardiac output due to cardiomyopathy might have aggravated hypoxic condition and it could be speculated that cardiomyopathy-induced systemic hypoxia gave rise to hypothermia of the skin as a result of peripheral vasoconstriction. This report presents a causal relationship of cardiomyopathy and subcutaneous fat necrosis of the newborn.

Purpose: This study aims to evaluate the effect of different pneumoperitoneum pressures on postoperative pain, especially by subcategorizing the pressures into 3 groups during laparoscopic cholecystectomy (LC). Methods: We conducted a prospective randomized, double-blinded study of 150 patients with benign and uncomplicated gallbladder disease. They were categorized into 3 groups. Each group (50 patients) underwent LC with different pneumoperitoneum methods: group VLP, very-low pressure (6–8 mmHg); group LP, low pressure (9–11 mmHg); and group SP, standard pressure (12–14 mmHg). The 3 groups were compared for pain intensity, duration, analgesic requirement, and complications. Results: The characteristics of the patients were similar among all groups. Postoperative pain scores at each time point (1, 2, 4, 6, 12, 24, and 48 hours) were not significantly different among the 3 groups. Further, operation time, hospital stay, the number of analgesic consumption doses, and postoperative complications were not significantly different among the 3 groups. Conclusion This study demonstrates no difference in postoperative pain among various pneumoperitoneum pressures during LC. Therefore, routine use of lower-pressure pneumoperitoneum is not recommended unless in selected patients who require low-pressure pneumoperitoneum surgery.

PURPOSE: To evaluate effectiveness of oblique approach under biplane fluoroscopic guidance in transthoracic fine needle aspiration biopsy. MATERIALS AND METHODS: Fourteen consecutive patients underwent transthoracic fine needle aspiration biopsy for subcarinal lesions. Subcarina was the only accessible biopsy site in 13 patients. Subcarinal biopsy was performed to determine the presence of metastasis in an enlarged subcarinal lymph node in the remaining one patient. Before biopsy, we evaluated the size and location of the lesion on preliminary plain chest X-ray film and CT scan. Under dual projection fluoroscopic guidence, biopsy was performed through right posterior intercostal space with the patient prone by using oblique approach. On 15 degree LAO projection the needle was directed to the area anterior to the spine and advanced to the line extending through the posterior wall of the main bronchus. RESULTS: Cytologic diagnosis was made in 12 out of 14 patients(accuracy 85.7%). The final diagnosis consisted of 5 squamous cell carcinoma, 5 small cell carcinoma, 1 adenocarcinoma and 1 adenosquamous carcinoma. Pneumothorax developed in 2 patients(14%) and was managed by chest tube drainage. Mild hemoptysis was observed in 2. CONCLUSION: Transthoracic fine needle aspiration biopsy using oblique approach under biplane fluoroscopic guidance is a relatively safe and sensitive method for the histologic diagnosis of subcarinal lesion.

BACKGROUND: The Histidine-Tryptophan-Ketoglutarate (HTK) solution has been shown to provide the excellent myocardial protection as a cardioplegia. The HTK solution has relatively low potassium as an arresting agent of myocardium, and low sodium content, and high concentration of histidine biological buffer which confer a buffering capacity superior to that of blood. Since HTK solution has an excellent myocardial protective ability, it is reported to protect myocardium from ischemia for a considerable time (120 minutes) with the single infusion of HTK solution as a cardioplegia. The purpose of this study is to evaluate the cardioprotective effect of HTK solution on myocardium when the ischemia is exceeding 120 minutes at two different temperature (10 to 12degrees C, 22 to 24degrees C) using the Langendorff apparatus. MATERIAL AND METHOD: Hearts from Sprague-Dawley rat, weighing 300 to 340 g, were perfused with Krebs-Henseleit solution at a perfusion pressure of 100 cm H2O. After the stabilization, the heart rate, left ventricular developed pressure (LVDP), and coronary flow were measured. Single dose of HTK solution was infused into the ascending aorta of isolated rat heart and hearts were preserved at four different conditions. In group 1 (n=10), hearts were preserved at deep hypothermia (10~12degrees C) for 2 hours, in group 2 (n=10), hearts were preserved at moderate hypothermia (22~24degrees C) for 2 hours, in group 3 (n=10), hearts were preserved at deep hypothermia for 3 hours, and in group 4 (n=10), hearts were preserved at moderate hypothermia for 3 hours. After the completion of the preservation, the heart rate, left ventricular developed pressure, and coronary flow were measured at 15 minutes, 30 minutes, and 45 minutes after the initiation of reperfusion to assess the cardiac function. Biopsies were also done and mitochondrial scores were counted in two cases of each group for ultrastructural assessment. RESULT: The present study showed that the change of heart rate was not different between group 1 and group 2, and group 1 and group 3. The heart rate was significantly decreased at 15 minutes in group 4 compared to that of group 1 (p<0.05 by ANCOVA). The heart rate was recovered at 30 minutes and 45 minutes in group 4 with no significant difference compared to that of group 1. The decrease of LVDP was significant at 15 minutes, 30 minutes and 45 minutes in group 4 compared to that of group 1 (p<0.001 by ANCOVA). Coronary flow was significantly decreased at 15 minutes, 30 minutes, and 45 minutes in group 4 compared to that of group 1 (p<0.001 by ANCOVA). In ultrastructural assessment, the mean myocardial mitochondrial scores in group 1, group 2, group 3, and group 4 were 1.02+/-0.29, 1.52+/-0.26, 1.56+/-0.45, 2.22+/-0.44 respectively. CONCLUSION: The HTK solution provided excellent myocardial protection regardless of myocardial temperature for 2 hours. But, when ischemic time exceeded 2 hours, the myocardial hemodynamic function and ultrastructural changes were significantly deteriorated at moderate hypotherma (22~24degrees C). This indicates that it is recommended to decrease myocardial temperature when myocardial ischemic time exceeds 2 hours with single infusion of HTK solution as a cardioplegia.
