Pallidothalamic tractotomy for Parkinson's disease with 1-year follow-up: a case report.
The pallidothalamic tract connects the globus pallidus internus and the ventrolateral portion of the thalamus, and ablation of the pallidothalamic tract (pallidothalamic tractotomy [PTT]) reportedly exerts antiparkinsonian effects. However, the detailed clinical course has not yet been elucidated. Here, we present the first single case report of PTT performed in a patient with Parkinson disease, with 1-year follow-up. ⋯ We present a rare case of PTT performed in a patient with Parkinson disease. PTT might be useful in patients who do not desire device implantation.

Review Case Reports
Intracranial DAVF as a reversible cause of dementia: case series and literature review.
Intracranial dural arteriovenous fistulas (DAVFs) can manifest with a reversible form of dementia and parkinsonism that may be related to medullary venous hypertension and impaired cortical venous drainage. We report a consecutive case series of patients with DAVFs who presented with cognitive decline and report angioarchitecture and outcomes of treatment. ⋯ Cognitive decline is a rare but reversible manifestation of DAVFs that have impaired venous drainage of the transmedullary veins and associated medullary venous hypertension.

The Need For Grass Root Innovation In Developing Countries: A Case For Stationary Binder Clips In Scalp Hemostasis.
The primary training in any surgical practice starts with tissue handling and effective hemostasis. Neurosurgical procedures start with an incision in the scalp and require summative use of mechanical hemostats and bipolar coagulation to achieve hemostasis. Though Raney clips are the most popular and effective in maintaining hemostasis, their high cost and nonreusability become deterrents for routine use in resource-stricken environments. ⋯ Stationery binder clips are a cost-effective, ready-to-use alternative for standard Raney clips.

Management of Choroid plexus tumors in infants and young children up to 4 years of age: An institutional experience.
Choroid plexus tumors (CPTs) are rare tumors characterized by papillary and intraventricular growth. The young age of presentation of such tumors, especially in infants, and the lack of consensus on adjuvant therapy in case of atypical choroid plexus papilloma (aCPP) and choroid plexus carcinoma (CPC) create dilemma for the management of such tumors. We discuss the presentation, management, complications, and outcome in 15 patients (children 4 years of age and younger) and review pertinent literature. ⋯ CPTs are challenging tumors in infants and very young children because of the potential for massive blood loss. CPP is associated with lesser blood loss and favorable outcome compared with aCPP and CPC. Massive blood loss in CPC and aCPP can be life threatening as has been shown in our series. CPC has a rapid proliferation potential as shown in one of our cases. Attempts at decreasing vascularization of such tumors should be made by various methods, including preoperative embolization and neoadjuvant chemotherapy; however, a consensus on this is lacking.

Review Case Reports
Re-recurrence of intracranial aneurysm with proximal vascular stenosis after primary clipping and secondary endovascular embolization: A case report and literature review.
It was known that a small number of patients could have intracranial aneurysm recurrences after either surgical clipping or endovascular embolization treatment. However, early recurrence within 1 month after the treatment and re-recurrence has rarely been reported before. ⋯ Re-recurrence of intracranial aneurysm could happen after initial successful treatment with surgical clipping and endovascular embolization. In addition to the patient's medical history and characteristics of the aneurysm, local vascular stenosis might also contribute to its recurrence. Close postoperative follow-up is required for these patients.
