Bifrontal-Parietal Ratio: A Novel Risk Factor for Cerebrospinal Fluid Overdrainage after Ventriculoperitoneal Shunting.

 This study aimed to examine potential risk factors associated with cerebrospinal fluid overdrainage after ventriculoperitoneal (VP) shunting.  We retrospectively examined the medical records of hydrocephalus patients who underwent VP shunting at a single institution between January 2011 and December 2017 and had a minimum 3-year follow-up. Variables studied included age, gender, hydrocephalus etiology, symptoms, shunt valve, ventricular catheter entry point, and neurosurgical history, including history of external ventricular drainage.

Independent Factors Associated with 30-Day In-Hospital Mortality from Acute Spontaneous Intracerebral Hemorrhage.

Objective: This study aims to investigate independent factors associated with 30-day mortality in patients with acute spontaneous intracerebral hemorrhage (SICH) before treatment.

Methods: A retrospective analysis was performed on medical records of patients hospitalized with acute SICH between 2019 and 2021. Data included personal history, hospital stay duration, symptom onset, chief complaint, underlying diseases, medication, and alcohol/smoking habits.

Long-term clinical outcomes of stereotactic radiotherapy for bilateral vestibular schwannomas in neurofibromatosis type 2 patients.

Purpose: The evidence for treating patients with neurofibromatosis 2-related vestibular schwannoma (VS-NF2) using hypofractionated stereotactic radiation therapy (HSRT) is limited. This study aimed to investigate clinical outcomes in patients with VS-NF2 treated with Robotic HSRT.

Methods: We retrospectively analyzed 25 NF2 patients with 48 VSs who were treated using Robotic HSRT at Ramathibodi Hospital from January 2009 to January 2020.

Clinical Outcomes of Intracranial Nonvestibular Schwannomas Treated with LinacBased Stereotactic Radiosurgery and Radiotherapy.

Background: Intracranial nonvestibular schwannomas arising from various cranial nerves excluding CN VIII are uncommon. Recently, stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (SRT) have been widely reported as effective treatment modalities for nonvestibular schwannomas. The purpose of this study was to study the long term clinical outcome for nonvestibular schwannomas treated with both XKnife and CyberKnife (CK) radiosurgery at one institution.

Central Spinal Canal Decompression for Lumbar Spondylosis with Uniportal Full-Endoscopic Interlaminar Approach: Technical Note and Preliminary Results in Thailand.

Objective: To describe surgical techniques for central spinal canal decompression with uniportal full-endoscopic interlaminar approach and report preliminary results of the first three cases.

Material And Method: Surgical technique for uniportal full-endoscopic interlaminar approach for central spinal canal decompression was described step by step. Three consecutive cases that were operated by this new technique were illustrated by retrospective chart review.

C2 anatomy for translaminar screw placement based on computerized tomographic measurements.

Study Design: Anatomical study.

Purpose: To evaluate the anatomy of the C2 lamina for translaminar screw placement based on computerized tomographic measurements.

Overview Of Literature: C2 translaminar screw insertion is a novel technique for atlanto-axial fixation.

Comparison between minimally invasive and open transforaminal lumbar interbody fusion.

Objective: To compare the clinical and radiographic outcomes between minimally invasive and open transforaminal lumbar interbody fusion (TLIF) for treatment of lumbar spondylolisthesis

Material And Method: A retrospective clinical study of24 consecutive cases of lumbar spondylolisthesis treated by minimally invasive TLIF (n = 12) or open TLIF (n = 12) was done at Ramathibodi Hospital between June 2008 and December 2009. The following parameters were compared between the two groups, clinical and radiographic outcomes, blood loss, operative time, length of hospital stay, and complications.

Results: The average duration of follow-up was 28 months (range, 24 months to 38 months).

Peroneal nerve injury associated with sports-related knee injury.

Object: This study analyzes 84 cases of peroneal nerve injuries associated with sports-related knee injuries and their surgical outcome and management.

Methods: The authors retrospectively reviewed the cases of peroneal nerve injury associated with sports between the years 1970 and 2010. Each patient was evaluated for injury mechanism, preoperative neurological status, electrophysiological studies, lesion type, and operative technique (neurolysis and graft repair).

Axillary nerve injury associated with sports.

Object: The aim of this retrospective study was to present and investigate axillary nerve injuries associated with sports.

Methods: This study retrospectively reviewed 26 axillary nerve injuries associated with sports between the years 1985 and 2010. Preoperative status of the axillary nerve was evaluated by using the Louisiana State University Health Science Center (LSUHSC) grading system published by the senior authors.

Oculomotor nerve schwannoma: a case report and review of the literature.

Background: Oculomotor nerve schwannomas are extremely rare tumors. There are only 40 cases reported in the literature. There is no standard treatment for these rare tumors.

Ossification of the posterior longitudinal ligament: a review.

Ossification of the posterior longitudinal ligament (OPLL) is most commonly found in men, the elderly, and Asian patients. There are many diseases associated with OPLL, such as diffuse idiopathic skeletal hyperostosis, ankylosing spondylitis, and other spondyloarthropathies. Several factors have been reported to be associated with OPLL formation and progression, including genetic, hormonal, environmental, and lifestyle factors.
