Mucocele is commonly found in frontal sinus. Mucocele of sphenoid sinus is rare and only 100 cases have been reported since Burg's description in 1889. Their etiology is still conjectural. These lesions are potentially more serious and are often misdiagnosed as pituitary tumor. The author experienced a case of sphenoid sinus mucocele develped headache, fever and CSF rhinorrhea. Plain skull, cisternography brain CT scan help the diagnosis of sphenoid sinus mucocele. A transnasal approach is considered best for case with extensive sphenoid sinus mucocele with bone destruction in the floor of sella turcica. The headache, fever and CSF rhinorrhea improved after surgery.

The author analyzed 177 consecutive cases of saccular, ruptured intracranial aneurysms admitted to the Department of Neurosurgery in Korea University Hospital during the period from August 1983 to July 1987. the results of analysis were summarized as follows. 1) Mean age of the patients was 50.4 years. 2) Incidence of clinical vasospasm was 27.2%(46/177) and of rebleeding was 10.7%(19/177). 3) Surgery was done for patients which accounts for 57.6% of all patients. Functional recovery was noted in 84 of the these surgically treated patients(84.6%). 4) The prognostic factors are age, hypertension, size of aneurysm, site of aneurysm, preoperative neurological state, vasospasm, hydrocephalus, rebleeding, timing of operation, multiplicity. 5) The mean size of aneurysms was 6.9mm. The direction of aneurysms was variable, but most of them pointed in the direction of blood flow in afferent arteries.

The object of this study was to investigate the influences of hypoglycemia and hypothermia on the direct current(DC) pontetial changes during cortical spreading depression(CSD) in rats. The induction of CSD was achieved by the application of KCI solution on the cortex of the frontal lobe. Hypoglycemia and hypothermia were induced respectively by insulin injection and the application of an ice pack. The DC potential changes during progressive hypoglycemia and hypothermia were measured with microelectrodes from the cortex of the parietal lobe of rats. Under contril condition, the rate of CSD was one per 5-10 min and the negative shift of DC potential was about 30 mV. The recovery time from negative shift to base line of DC potential was about 40 sec. In rats treated with insulin, the amplitude of DC potential shift was unaffected by hypoglycemia. The recovery time of DC shift was 40+/-2.26 sec at normoglycemia and it was delayed progressively as the blood glucose level lowered. The mean of it was 63+/-8.02 sec at 30 mg/dl and 77.1+/-22.0 sec with the blood glucose falling below 20 mg/dl. The same delay in the recovery time as seen in the hypogylcemia group was observed in rats treated with hypothermia. The recovery time of DC shift was 39.4+/-3.02 sec in normothermia(36.5degrees C), but it was delayed to 61.15+/-4.15 sec at 30degrees C and 96.67+/-14.92 sec at 26degrees C body temperature. This study suggested that each condition of profound hypoglycemia below 30 mg/dl and hypothermia below 30degrees C was to be harmful to the ion homeostasis and the integrity of the cell membrane and it may lead neurons to death.

Carboplatin intra-arterial chemotherapy(IAC) has an advantage of increased uptake during the first passage of the drugs through tumor capillaries. Although not common, this type of therapy is known to cause neurological complications, myelosuppression, and ototoxicity. However, the incidence of ocular toxicity is reported to be rare. Eleven of our patients with glioma(Grade II Astrocytoma: 3, Grade III Astrocytoma: 1, Grade IV Astrocytoma: 5, Gliofibroma: 1, Oligodendroglioma: 1) underwent IAC regimen with carboplatin(300mg/m2) which were administrated after blood-brain barrier disruption. Of there, 3 patients had ocular complications after supra-ophthalmic IAC injection of carboplatin but fully recovered following steroid therapy. Although our results from IAC seem to be favorable for these patients, we suggest that its complications, such as ocular toxicity, need to be carefully considered prior to treatment.

The authors report two cases of paratrigeminal syndrome. They were male and involved in the left side, and had no known hypertension. The syndrome was produced and encountered in patients who had undergone a percutaneous carotid angiography and surgery with ligation of common carotid artery for the treatment of carotidcavernous sinus fistula. The clinical manifestations were unilateral, intense, throbbing supraorbital and periorbital pain recurring regularly, accompanied by drooping of the eye lid and miosis with normal sweating on the same side as the pain. The cases were treated conservatively with diphenylhydantion and antimigraine preparations with apparent success. It is probable that the underlying pathology of the syndrome in these cases may be compression of the internal carotid sympathetic fibers due to swelling of the interal carotid arterial wall. The clinical features and courses were compatible with those of group 2 of Raeder's syndrome.

STUDY DESIGN: A retrospective study. OBJECTIVES: To analyze the clinical and radiological results of different surgical methods in osteoporotic vertebral fracture patients, with neurologic deficits in the thoracolumbar junction. SUMMARY OF LITERATURE REVIEW: Various surgical methods have been reported for osteoporotic vertebral fractures, with neurologic deficits, in the thoracolumbar junction. These are: anterior decompression, anterior decompression and anterior or posterior reconstruction, and Egg shell procedure. However, it is controversial as to which method is better. MATERIALS AND METHODS: 13 patients that had undergone surgical treatment for osteoporotic vertebral fractures, with neurologic deficits, With a mean age of 68+/-8.4, ranging from 51 to 79 years. Six of the cases were male and seven were female. The mean follow up period was 18 months. The patients were divided into two groups. Group A (n=8): Anterior decompression, anterior interbody fusion, with cage or autologous strut iliac bone block, and instrumentation (anterior or posterior). Group B (n=5): Posterior decompression and posterior reconstruction (egg shell procedure). The kyphotic angles, neurologic improvements and complications in each group were analyzed preoperatively, postoperatively and at final follow up. RESULTS: In group A, the mean kyphotic angles were 29+/-5.9 degrees, 18+/-6.7 degrees and 23+/-7.7 degrees preoperatively, postoperatively and at the final follow up, respectively. In group B, the mean kyphotic angles were 31+/-1.1 degrees, 12+/-6.3 degrees and 18+/-5.5 degrees preoperatively, postoperatively and at the final follow up, respectively. In group A, 3 and 5 patients were graded as Frankel grades C and D, respectively. In group B, 1, 1 and 3 patients were graded as Frankel grades B, C and D, respectively. The neurological status improved in all the patients, by mean 1.1 grades in group A and 1.2 grades in group B. In group A, postoperative transient dyspnea and screw loosening occurred in one and two patients, respectively. In group B, postoperative paralytic ileus and screw loosening occurred in one two patients, respectively. CONCLUSIONS: Posterior decompression and posterior reconstruction (egg shell procedure) was an effective surgical method, equivalent to an anterior or anterior and posterior procedure, for osteoporotic vertebral fracture patients, with neurologic deficits.
