OBJECTIVE: The goal of this study was to review the etiologies, phathophysiology, clinical presentations and to compare the results of the surgical methods of subdural empyema especially in infants. PATIENTS AND METHODS: We reviewed the clinical data of five infantile subdural empyemas experienced in our hospital from 1993 to 1998 which were all surgically treated by craniotomy or burr hole trephination. We experienced five cases of infantile subdural empyema: two males and three females. The ages ranged from 40 days to 11 months. RESULTS: The etiologies of all five cases were unproven but all five cases had meningitis before the subdural empyemas were diagnosed. The causative organism in one was streptococcus pneumoniae, and the other were unknown. Two were treated with craniotomy(one with a good outcome and the other died) and three were treated with burr hole trephination(all three had a good outcome). CONCLUSION: Subdural empyema is a rapid progressing disease and it is important to detect and treat in the early stages of disease. The choice of surgical method must be based on the stage of the disease and its location in the cranial cavity.

We present two patients with a cerebral palsy who developed cervical myelopathy long from term involuntary movements. Frequently instability with a premature onset of spondylosis of the cervical spine is found in an athetoid cerebral palsy patient. These structural abnormalities appear to be related to the athetoid motion of neck in a cerebral palsy. The combination of a disk degeneration and listhetic instability with a narrow canal predisposes these patients for the relatively rapid progression to a devastating neurological defect. Early surgical management is a treatment of choice for the cervical myelopathy associated with an athetoid cerebral palsy.

Although severe hemolytic diseases of the newborn triggered by anti-M are very rare, anti-M alloantibodies have been known to be associated with a cause of multipie intrauterine death. Serological and hematological investigations have been reported on a woman who experienced four multiple intrauterine deaths due to anti-M. The mothers blood type was of group A, NN and the husbands cells were of group B, MN. In the serological examination at 9th week's gestation of the fifth pregnancy, anti-M antibodies were identified in her serum. The antibodies comprised IgM saline agglutinin at a titer of 16 at 4 degrees C and IgG agglutinin reacted in an indirect antiglobulin technique at a titer of 4 at 37 degrees C. She underwent high-dose immunoglobulin infusion therapy on a monthly program from 3rd month gestation and a total of 6 times of intravenous immunoglobulin was given. The anti-M titer did not rise during the pregnancy. She delivered a live girl by cesarean section at the 37th week because of a failure of induction. The childs blood type was of group O, MN. The child was discharged and developed normally.

OBJECTIVE: The purpose of this study was to determine the efficacy of short segment fixation following postural reduction for the re-expansion and stabilization of unstable burst fractures in patients with osteoporosis. METHODS: Twenty patients underwent short segment fixation following postural reduction using a soft roll at the involved vertebra in cases of severely collapsed vertebrae of more than half their original height. All patients had unstable burst fracture with canal compromise, but their motor power was intact. The surgical procedure included postural reduction for 2 days and bone cement-augmented pedicle screw fixations at one level above, one level below and the fractured level itself. Imaging and clinical findings, including the level of the vertebra involved, vertebral height restoration, injected cement volume, local kyphosis, clinical outcome and complications were analyzed. RESULTS: The mean follow-up period was 15 months. The mean pain score (visual analogue scale) prior to surgery was 8.1, which decreased to 2.8 at 7 days after surgery. The kyphotic angle improved significantly from 21.6+/-5.8degrees before surgery to 5.2+/-3.7degrees after surgery. The fraction of the height of the vertebra increased from 35% and 40% to 70% in the anterior and middle portion. There were no signs of hardware pull-out, cement leakage into the spinal canal or aggravation of kyphotic deformities. CONCLUSION: In the management of unstable burst fracture in patients with severe osteoporosis, short segment pedicle screw fixation with bone cement augmentation following postural reduction can be used to reduce the total levels of pedicle screw fixation and to correct kyphotic deformities.

8.Intravascular Migration of an Epidural Catheter Despite using Several Testing Maneuvers.

Epidural anesthesia for cesarean section allows the mother to be awake, minimizes or completely avoids the problem of maternal aspiration and neonatal drug depression from general anesthetics. But epidural anesthesia has the potential to produce local anesthetic systemic toxicity or inadvertent high spinal block which is due to unintentional administration of drug into an epidural vessel or subarachnoid space. There are several ways to avoid these complications. These include careful aspiration of epidural catheter, fractionation of the epidural dose, and the use of epinephrine containing epidural test dose before injection of epidural dose. We report a case of a pregnant woman who had developed a seizure after an injection of the epidural anesthetic. This occurred despite using the techniques of aspiration and epinephrine containing epidural test dose injection. So we thought that the seizure occurred probably by the migration of epidural catheter while changing positions and it should be considered in all cases of epidural anesthesia.

Six cases of traumatic intracranial aneurysms are presented, two located on the internal carotid artery, two on the anterior cerebral artery, one on the middle cerebral artery, and one on the middle meningeal artery. Three of the 6 cases were associated with skull fracture. Five cases were treated:two by clipping, two by trapping and one by excision & coagulation of the lesion. Due to increasing use of brain CT to substitute angiogram during the initial surveys of head injury patients, traumatic aneurysms are often overlooked and the diagnosis delayed. Since the clinical course of traumatic aneurysm is variable and its high mortality rate, immediate cerebral angiography & early proper treatment are recommended whenever clinical suspicion of traumatic aneurysm is aroused or/and delayed neurological deterioration is detected after head injury. In this study, the authors tried to find out the clues for early diagnosis of traumatic intracranial aneurysms.
