Abstract

INTRODUCTION:
Circumferential aneurysms, which incorporate &gt;180 degrees of the circumference of the parent vessel, present a unique therapeutic challenge, particularly in circumstances in which a deconstructive treatment strategy is not feasible. We detail a novel technique for endovascular parent vessel reconstruction with aneurysm embolization.

METHODS:
We performed a retrospective review of the prospectively maintained databases of our two institutions to identify cases in which a balloon-in-stent technique had been used to treat circumferential aneurysms. During the first stage of this technique, a stent (Neuroform [Boston Scientific, Natick, MA], Multilink Vision [Guidant, Indianapolis, IN], or Bx Velocity [Cordis, New Brunswick, NJ]) is placed across the neck of the aneurysm to achieve parent vessel reconstruction. During the second stage, aneurysm coil embolization is performed with a compliant temporary occlusion balloon (Sentry [Boston Scientific, Natick, MA] or Hyperglide [Microtherapeutics, Irvine, CA]) placed within the stent to unambiguously demarcate and protect the parent vessel. In some cases, during the course of the embolization, coils project over and obscure the parent vessel in both working views. Before each coil detachment, the protection balloon is deflated under blank fluoroscopic roadmap visualization. The absence of shifting of any portion of the coil mass during balloon deflation indicates that the introduced coil is external to the stent-reconstructed parent vessel (i.e., within the aneurysm) and can be detached. This process is repeated until satisfactory aneurysm embolization is achieved. After embolization, the balloon catheter may be exchanged for a stent delivery system to facilitate the placement of a second stent.

RESULTS:
Seven patients underwent balloon-in-stent-assisted embolization over a 15-month period. Three were performed for internal carotid aneurysms, three for basilar trunk or basilar apex aneurysms, and one for a dissecting/fusiform V4 segment vertebral artery aneurysm. In three cases, the presence of the inflated balloon facilitated the manipulation of the image intensifier into a position which produced a “down-the-barrel” view of the parent vessel. In the four additional cases, for anatomic reasons, this view could not be achieved and coil mass projected over the reconstructed parent vessel in both views. Partial aneurysm occlusion (75–90%), was achieved in five cases, and near complete (&gt;95%) occlusion was achieved in two cases. Complications included two significant retroperitoneal hematomas and two brainstem infarcts, both of which resulted in hemisensory symptoms.

CONCLUSION:
The balloon-in-stent technique provides a practical and safe treatment strategy for the management of circumferential aneurysms that are not amenable to deconstructive embolization.

Abstract

OBJECTIVE:
Controversy exists about the indications and timing for surgery in head injured patients with an intradural mass lesion. The aim of this study was to survey contemporary approaches to the treatment of head injured patients with an intradural lesion, placing a particular focus on the utilization of decompressive craniectomy.

METHODS:
A prospective international survey was conducted over a 3-month period in 67 centers from 24 countries on the neurosurgical management of head injured patients with an intradural mass lesion and/or radiological signs of raised intracranial pressure. Information was obtained about demographic, clinical, and radiological features; surgical management, and mortality at discharge.

RESULTS:
Over the period of the study, data were collected about 729 patients consecutively admitted to one of the participating centers. The survey included 397 patients with a severe head injury (Glasgow Coma Scale [GCS] 3–8), 155 with a moderate head injury (GCS 9–12) and 143 patients with a mild head injury (GCS 13–15). An operation was performed on 502 patients (69%). Emergency surgery (&lt;24 h) was most frequently performed for patients with an extracerebral mass lesions (subdural hematomas) whereas delayed surgery was most frequently performed for an intracerebral hematoma or contusion. Decompressive craniectomy was performed in a substantial number of patients, either during an emergency procedure (n = 134, 33%) or a delayed procedure (n = 47, 31%). The decompressive procedure was nearly always combined with evacuation of a mass lesion. The size of the decompression was however considered too small in 25% of cases.

CONCLUSION:
The results provide a contemporary picture of neurosurgical surgical approaches to the management of head injured patients with an intradural mass lesion and/or signs of raised intracranial pressure in some Neurosurgical Units across the world. The relative benefits of early versus delayed surgery in patients with intraparenchymal lesions and on the indications, technique and benefits of decompressive craniectomy could be topics for future head injury research.
Isolated Abducent Nerve Palsy after Microvascular Decompression for Trigeminal Neuralgia: Case Report
Authors: Choudhari Kishor A. 
Published: December 2005

Abstract

OBJECTIVE AND IMPORTANCE:
Microvascular decompression (MVD) is a safe and effective treatment for trigeminal neuralgia. Isolated postoperative ipsilateral abducent nerve palsy is an extremely rare complication of this procedure and has not been reported before. The author wishes to report this rare complication, discuss its aetio-pathogenesis and the natural course.

CLINICAL PRESENTATION:
A 57-year-old man underwent MVD for right sided medically refractory trigeminal neuralgia based on the MRI finding of ectatic basilar artery compression at its root entry zone. The procedure was uneventful with complete relief of pain. However, he developed isolated ipsilateral sixth nerve palsy following surgery that lasted for six weeks.

INTERVENTION:
Anterior displacement of tortuous and dilated basilar artery to create space between the artery and the nerve during MVD operation probably resulted in inadvertent neuropraxia to the abducent nerve that was located immediately anterior to the artery but was not in the surgical field. Immediate sixth nerve palsy resulted post-operatively. A conservative route was adopted with spontaneous improvement of the extraocular eye movements after six weeks.

CONCLUSION:
Isolated abducent nerve damage is a rare complication of the MVD procedure. Surgical manipulation of the dilated and tortuous vessels located anterior to the trigeminal nerve may cause indirect stretching of the delicate abducent nerve with resultant neuropraxia. This complication is difficult to recognize and prevent intra-operatively as the nerve lies on the far side of the artery. Fortunately, spontaneous recovery of the neural function seems to be the most likely outcome.
Fracture of Subthalamic Nucleus Deep Brain Stimulation Hardware as a Result of Compulsive Manipulation: Case Report
Authors: Machado Andre G. , Hiremath Girish K. , Salazar Fortino , Rezai Ali R. 
Published: December 2005

Abstract

OBJECTIVE AND IMPORTANCE:
Trichotillomania (TTM) is an impulse control disorder characterized by the recurrent pulling of one's hair resulting in noticeable hair loss. There has been no definite association drawn between Parkinson's disease (PD) and TTM, although there is a suggestion that obsessive-compulsive symptomatology may be more prevalent in left-side predominant PD. We believe that it is important to be aware of psychiatric comorbidities in the surgical treatment of PD, as they may significantly impact the postoperative course.

CLINICAL PRESENTATION:
We describe the case of a 58-year-old woman with an eleven-year history of left-side predominant PD who also suffered from TTM. She underwent subthalamic nucleus deep brain stimulation (STN-DBS) and subsequently developed significant wound complications of her left-sided deep brain stimulation leads. It was noted during the postoperative period that the patient was picking her left-sided, but not right-sided, incision—a behavior that was felt to be a part of this patient's impulse control disorder.

INTERVENTION:
Multiple wound revisions and eventual replacement of her left-sided deep brain stimulation lead was performed as a result of hardware malfunction secondary to wound manipulation by the patient.

CONCLUSION:
Before surgery, this patient's TTM was right-sided, but after subthalamic nucleus deep brain stimulation, her wound picking was only left-sided. This case suggests that subthalamic nucleus deep brain stimulation may have a role in unleashing the symptomatology of TTM through an as yet poorly understood mechanism. Furthermore, there is also an implication that the pathophysiology of PD and TTM may be intertwined.

Published: December 2005

Abstract

OBJECTIVE:
To better understand the presentation, management, and outcome of syringobulbia in the pediatric age group.

METHODS:
The University of Iowa pediatric neurosurgery database was searched for patients under the age of 18 with a diagnosis of syringobulbia. The patients' records were retrospectively reviewed for demographic data, chief complaint and presenting symptoms, neurological and radiographic findings, treatment, outcome, and complications. Children with open neural tube defects and Chiari II malformations were excluded.

RESULTS:
Six pediatric patients were identified as meeting inclusion criteria. The average age at time of surgery was 14.8 years. The chief complaints were vision impairment in three children and numbness, gait instability, and headache worsened with Valsalva in one patient each. Other prominent symptoms included sleep apnea and weakness. All patients showed at least one cranial nerve dysfunction. Radiographs revealed hindbrain herniation and associated syringomyelia in all cases. Two patients had scoliosis. Treatment was posterior fossa decompression with cerebellar tonsillar shrinkage, opening of foramen of Magendie, and duraplasty. Two patients also required concomitant ventral decompression. The cavity of syringobulbia communicated with syringomyelia and the fourth ventricle in most children but was distinct from the fourth ventricle. Two patients received fourth ventricle to subarachnoid shunts. Follow-up averaged 3.2 years, and all patients clinically improved after surgery. Magnetic resonance imaging documented resolution of syringobulbia in all cases, with syringomyelia improving in all cases. There was no permanent morbidity or mortality in the series.

CONCLUSION:
Syringobulbia is strongly associated with Chiari malformation and syringomyelia, and patients often present because of cranial nerve palsies. Posterior fossa decompression is a safe and effective treatment.
Synthesis of Highly Fluorescent Polythiophene with Polystyrene Branches Using ATRP
Authors: Shen Jie , Ogino Kenji 
Published: December 2005

Abstract
The graft copolymer containing a polythiophene (PT) backbone and polystyrene branches with superior solubility and processability was obtained by the atom transfer radical polymerization (ATRP) of styrene from the initiating sites on the PT backbone. The grafted PS branches could separate the PT chains and form a PS matrix for effectively trapping the PT in a solution conformation, which was advantageous to the improvement of fluorescent efficiency in the solid state.

Correlation between catalytic performance and surface acidity has been found.
Formation of One-dimensional Crooked Gold Nanocrystals by Electrochemical Technique with Surfactant Solution
Authors: Huang Chien-Jung , Wang Yeong-Her , Chiu Pin-Hsiang , Lin Jing-Jenn 
Published: December 2005

Abstract
This study demonstrates the synthesis of one-dimensional (1D) crooked gold (Au) nanocrystals by an electrochemical method with surfactant. For example, the primary surfactant may be cetyltrimethylammonium bromide (CTAB), and the auxiliary surfactant may be tetradodecylammonium bromide (TTAB) with isopropanol (IPA) solvent. The formation of crooked Au nanocrystals was induced by aggregation of many small Au nuclei between the several large Au nanoparticles during growth, causing the small Au nuclei to link to the large Au nanoparticles forming crooked Au nanocrystals.

Authors: Daniel Marie-Christine , Sakamoto Aiko , Ruiz Jaime , Astruc Didier , Nishihara Hiroshi 
Published: December 2005

Abstract
A family of 3-ferrocenylazobenzene-attached dendrimers, 9mer, 27mer, and 81mer, which is the first series of redox-active photochromic dendrimers exhibit photochromism responding to three different light sources, i.e., 365, 436, and 546 nm lights. Decreases in the size of the dendrimers induced by trans-to-cis photoisomerization appeared and became more significant with increases in the size of the dendrimers up to 81mer. Electrochemical treatment of the 81mer provided a photo-sensitive and redox-active dendrimer film-coated electrode.

Published: December 2005

Abstract
Synthesis of Cu and Ni–Cu particles from their aqueous formate solution by hydrogen reduction in hot-compressed water was carried out at 673 K with a titanium alloy autoclave. Hydrogen was produced by thermal decomposition of the formates. Metal particles having an average size of around 500 nm were produced without any additives. Ni–Cu metal alloy particles having different compositions were obtained by changing Cu/Ni molar ratio in starting solutions.

Authors: Kawatsuki Nobuhiro , Fujii Yasuhito , Kitamura Chitoshi , Yoneda Akio 
Published: December 2005

Abstract
Photoinduced orientation of a new photo-cross-linkable liquid crystalline polymer film comprising a 4-methoxycinnamoyloxy group connected with a tolane moiety (PMCT6M) is presented. High molecular reorientation order with a birefringence value of 0.27 is achieved by exposing the film to linearly polarized ultraviolet light and subsequent annealing. The required degree of the photoreaction for the effective reorientation is 2–5 mol %. Small amount of photo-cross-linked mesogenic groups controls the thermal enhancement of the molecular reorientation.

Authors: O'Neal Clifford C. , Hawke John P. , Weirich Charles R. 
Published: December 2005

Abstract
A 1-year study was conducted from February 1999 to January 2000 to determine the effects of low levels of salinity on selected hematological parameters (total protein, hematocrit, leukocrit, and osmolality) and the health of channel catfish Ictalurus punctatus reared in ponds managed under the multiple cropping production strategy. We stocked 2,000 catfish into 15 ponds (0.08 ha each) that we subdivided into five replicate ponds per each of three NaCl (salinity) treatments: freshwater conditions (nominal salinity = 0 g/L of water) or adjusted salinities of 1.5 or 3 g/L. Total protein, hematocrit, and plasma osmolality for fish reared at the NaCl-induced salinities were significantly higher than those for fish cultured in freshwater. Although the leukocrit of fish reared at a salinity of 3 g/L was significantly higher than that of fish reared in freshwater or at 1.5 g/L, all were within the normal ranges reported for channel catfish. Although two bacterial diseases known to routinely affect channel catfish (enteric septicemia of catfish and motile aeromonad septicemia) were observed at all salinity levels tested, columnaris disease was not observed during the study. Parasitic infections during certain months were less severe for fish reared in saline ponds than in freshwater. The results indicate that the hematological variables measured in this study were higher at increased salinities but within the ranges reported as normal for channel catfish.
