We operated upon 12 patients with macroadenoma and two with Rathke's cleft cyst using an endoscope through a nasal speculum. Pure endoscopic endonasal transsphenoiolal approach (TSA) was performed in nine patients and endoscope-assisted microscopic endo nasal TSA in five. A thin-bladed nasal speculum was used to achieve a wide, almost midline, pathway without an incision at the septal mucosa. ⋯ Two patients with Rathke's cleft cyst did not show recurrence. No patient showed sinonasal or endocrinological complications. Versatile use of the endoscope through a widened nasal cavity using a nasal speculum is a promising tool for the treatment of pituitary lesions.

Review Case Reports
Intracavernous schwannoma of the abducens nerve: a review of the clinical features, radiology and pathology of an unusual case.
We report a case of an intracavernous abducens nerve schwannoma presenting in a 19 year old male of Mediterranean origin. This is only the second report of an abducens nerve schwannoma located entirely within the cavernous sinus. ⋯ A literature search has identified only four other abducens nerve schwannomas arising completely or partly within the cavernous sinus. We review these cases and aspects of other ocular cranial nerve schwannomas.

Review
Intraoperative magnetic resonance imaging: considerations for the operating room of the future.
Recent technological advances have made possible the introduction of the magnetic resonance imaging (MRI) system into the operating room to guide neurosurgical interventions. We review the possibilities and limitations associated with various open-configuration magnet designs, including systems from the Phillips, Siemens, General Electric, Odin and IMRIS designs. This technology has been shown to be a feasible adjunct to current neurosurgical management of intracranial brain tumors for both biopsy and resection procedures and shows significant potential applications for epilepsy surgery, spine surgery and for minimally invasive interventional techniques. Combined with other surgical planning modalities, intra-operative MRI scanners provide an evolutionary influence on the design of today's operating room.

Multicenter Study
An Australian experience with temozolomide for the treatment of recurrent high grade gliomas.
Temozolomide has an evolving role in the treatment of high grade gliomas. Recent studies suggest that temozolomide is well tolerated and efficacious. This study retrospectively analysed the activity and toxicity associated with temozolomide at two Australian centres over a 24 month period. ⋯ Of the 56 patients, 15 (27%) achieved complete or partial response and 18 (32%) achieved minor response or stable disease. There were no episodes of febrile neutropenia and temozolomide was generally well tolerated. In conclusion, temozolomide is an active therapy in patients with recurrent high grade glioma and our results concord with published studies.

Multicenter Study
Stroke in Indonesia: a first large prospective hospital-based study of acute stroke in 28 hospitals in Indonesia.
Stroke is an increasing cause of morbidity and mortality in Indonesia. Data on clinical patterns of hospitalized Indonesian stroke patients are still not available. This study is a part of ASNA (ASEAN Neurological Association) Stroke Epidemiological Stu dy aimed to investigate clinical profile of stroke in seven ASEAN countries with the same protocol. ⋯ The most common risk factors were hypertension, heart disease, cigarette smoking and diabetes mellitus. Recurrent stroke was found in nearly 20% of patients. Ischemic stroke was the most frequent and the majority of the study subjects were discharged alive and improved.
