Treatment of phenylketonuria-associated tremor with deep brain stimulation: case report.
Phenylketonuria (PKU) is an inborn error of metabolism that causes severe neurological impairment, despite dietary treatment. We present a case of PKU-induced cerebellar tremor treated with deep brain stimulation. There have been no previously reported cases of a patient with a PKU tremor treated with deep brain stimulation. ⋯ Immediately after surgery, the patient had nearly complete resolution of intention tremor in the left arm. His resting tremor in the left hand was also greatly improved. The 30-month follow-up examination revealed maintenance of the immediate postoperative improvement.

Rheumatoid arthritis frequently affects the craniovertebral junction (CVJ) and may lead to severe neck pain, quadriparesis, and respiratory dysfunction. Surgery in rheumatoid nonambulatory (Ranawat Class IIIb) patients carries a significant risk. This study presents the surgical outcome of Class IIIb patients with CVJ rheumatoid myelopathy and reviews the literature. ⋯ A large subset of patients with CVJ rheumatoid myelopathy may reach Class IIIb. These patients have unique management considerations. Surgery (despite high morbidity) often remains the best therapeutic option available to them. Improvement of even one grade in their Ranawat score from Class IIIb to Class IIIa brought about by surgery confers on them a significant benefit in terms of their quality of life and survival.

Patients with idiopathic scoliosis often have a noticeable rib deformity that frequently persists after corrective surgery. Open thoracoplasty has been the traditional method of reducing rib deformity. Recently, however, video-assisted thoracoscopy (VATS) has been used to perform thoracoplasty. There have been no long-term follow-up studies on VATS thoracoplasty, nor have there been outcome scores to assess the results of thoracoplasty procedures. We present our experience using VATS thoracoplasty with long-term follow-up and propose an outcome grading system for thoracoplasty. ⋯ VATS provides an alternative, minimally invasive route to perform thoracoplasty. VATS incisions are much smaller and more cosmetically appealing than open thoracoplasty incisions. Long-term follow-up indicates good to excellent patient outcomes.

Surgical site infections (SSIs) after pediatric intracranial surgery for craniofacial malformations are relatively common and potentially serious nosocomial infections. Despite this, few studies have been published on this topic. We performed a retrospective study to determine the incidence of and factors associated with SSIs after intracranial surgery for craniofacial malformations at a single multidisciplinary craniofacial center during a 6-year period. ⋯ In this study, the presence of a complicated diagnosis and a number of other factors were associated with an SSI after pediatric intracranial surgery for craniofacial malformations. We speculate that a complicated diagnosis may be a marker for other factors that contribute to the risk of an SSI. Future studies investigating SSIs after intracranial surgery should consider these factors.

In a recent article, our experience and knowledge of the clinical picture, microsurgical anatomy, and long-term surgical outcome of resecting tuberculum sellae meningiomas was described in detail. We now present our surgical technique in a pictorial and video format for the benefit of neurosurgeons in training, as well as for general critique. Attention is given to the details of surgery: patient positioning, surgical approaches, technique of tumor removal, and postoperative care.
