ABSTRACT
OBJECT: Decompressive laminectomy offers an effective surgical treatment of lumbar spinal stenosis. The purpose of this study was to compare the elements of treatment commonly associated with successful outcomes in the assessment of laminectomies - operating room times, estimated blood loss, length of stay, and complications - of the minimally invasive and open approach laminectomies. METHODS: We retrospectively reviewed the medical records and relevant imaging of 126 patients who underwent surgical decompression for lumbar stenosis. Thirty-eight patients underwent bilateral decompression via a unilateral minimally invasive technique, while 88 patients underwent bilateral decompression via a standard open technique. A chart review was performed to determine intraoperative blood loss, length of operative time, length of hospital stay, and number and nature of complications. RESULTS: The minimally invasive lumbar laminectomy (MID) patients had shorter operating room times, less estimated blood loss, shorter length of stay, and fewer complications. CONCLUSIONS: Bilateral decompression of lumbar spinal stenosis via a unilateral approach involves shorter operating times and less blood loss, less muscle dissection, fewer and less severe complications, and better mobility in the immediate postoperative period than open decompressive techniques. In addition, this technique is very similar to the commonly performed microendoscopic discectomy and is easily mastered over time.

BACKGROUND: Osteomas of the paranasal sinuses rarely lead to intracranial manifestations. We present an unusual case of a frontal sinus osteoma leading to intracerebral abscess formation. CASE DESCRIPTION: A 51-year-old Hispanic man presented with increasing frontal headaches, new onset seizure, lethargy, global dysphasia, and unilateral hemiparesis. CSF studies demonstrated mild pleocytosis. Neuroradiological studies revealed an opacity filling the left frontal sinus, as well as a ring-enhancing mass with surrounding edema in the left frontal lobe. The patient was surgically treated with a left frontal osteoplastic craniotomy and removal of the abscess and bony mass. Intraoperative cultures were positive for Streptococcus pneumoniae. Pathology revealed bony tumor consistent with osteoma. The patient's neurological status improved to baseline after surgery. CONCLUSION: The frontal sinus osteoma was associated with rapid development of a frontal lobe abscess, requiring emergent surgical debridement. Although rare, intracerebral manifestations should be considered and expected as a cause of new neurological deficits in the presence of paranasal sinus osteoma.

Epidural hematomas remain at the pinnacle of neurosurgical emergencies, representing approximately 3% to 8% of all serious head injuries. Mortality from this entity is usually prevented once the diagnosis is clear. Although readily recognized on non-contrast head CT, the occasional patient may go on to develop a clinically significant hematoma after an initial negative CT. This phenomenon is appropriately termed delayed epidural hematoma. We present a case in which a 3-year-old boy developed a large epidural hematoma, which was not evident until the second CT, several hours after the injury. We feel that maintaining a high clinical suspicion, coupled with a low threshold for CT scanning, is the key to morbidity prevention in this illness.

We studied the efficacies of ofloxacin, rifampin, and clindamycin in a Staphylococcus aureus abscess model and seven antimicrobial regimens in an intracellular killing assay. Ofloxacin plus rifampin was the most effective regimen in the abscess model, and rifampin and ofloxacin were the most active regimens in the intracellular killing assay.
