Most trigeminal neuralgia is attributable to vascular compression of the root entry zone of the trigeminal nerve at the pons. Only about 5-10% of trigeminal neuralgia cases are caused by direct compression by ipsilateral cerebellopontine angle tumors. Trigeminal neuralgia caused by contralateral posterior fossa tumors are extremely rare. ⋯ This report describes a case of large meningioma in the left occipital region. The patient's right facial pain subsided gradually after tumor excision. This neuralgia is likely due to a displaced adjacent vessel that developed following brainstem distortion by the tumor.

Apoptosis is an important element of the secondary processes that occur after spinal cord injury. Calpain and caspases are key proteases in apoptotic cell death. We evaluated the neuroprotective effects of SJA6017 (a calpain inhibitor) and measured functional recovery in a rat spinal cord injury model. ⋯ Tarlov scores revealed that group 3 rats also had ameliorated recovery of limb function. Our results demonstrate that treatment with SJA6017 reduces apoptotic cell death, preserves spinal cord tissue and improves functional outcome. Treating calpain-induced apoptosis with this agent may be a feasible therapeutic strategy for patients with spinal cord injury.

Controlled Clinical Trial
Intravenous theophylline decreases post-dural puncture headaches.
Post-dural puncture headache (PDPH) is a common complication of lumbar puncture. As invasive treatments for PDPH have known complications, pharmacologic management may be preferable. The aim of this study was to evaluate and to compare the efficacy of intravenous theophylline treatment for PDPH, in comparison with a placebo. ⋯ Intravenous theophylline infusion is an easy, rapid, minimally invasive, an effective treatment for PDPH. It may be attempted in PDPH patients before invasive techniques are used. To the best of our knowledge, this is the first report on the effect of intravenous infusion of theophylline compared with a placebo in the treatment of PDPH.

The aim of this study was to identify the risk factors associated with bone grafts infection after cranioplasty. Eighty-four cranioplasties were performed on 75 patients between 2002 and 2006. Cryopreserved bone grafts were used as graft material in group 1 and polymethylmethacrylate (PMMA) was used in group 2. ⋯ Multiple procedures and insufficient time intervals increase the risk of infection. Interrupting the wound healing process may be the cause of infection. PMMA is a safe material for cranioplasty regardless of previous infection.

Biography Historical Article
Pediatric neurosurgical techniques in the 15th century.
The renowned Turkish surgeon Serefeddin Sabuncuoğlu (1385--1468 AD), delineates management of various pediatric neurosurgical diseases such as head trauma, spinal trauma, and intrauterine and infantile hydrocephalus, as well as basic surgical principles in his textbook Cerrahiyyetü'l Haniyye, which consists of three chapters dealing with a variety of surgical specialities. The sections on neurosurgery are still relevant to modern medicine. The book combines previous knowledge of Greek, Roman, Arabic, and Turkish surgery. Today, Sabuncuoğlu is recognized as a pioneer of pediatric neurosurgery.
