Objective: The objective of this study is to develop a preliminary model for prediction of chronic subdural hematoma (CSDH) recurrence for adult Filipinos who underwent CSDH surgery.

Methods: This study addresses a retrospective cohort of 71 adult patients who underwent CSDH surgery at a tertiary medical center in the Philippines. The outcome of interest was recurrence of CSDH detected on post-operative scans after discharge.

Background: Spinal aneurysmal bone cysts (ABCs) are challenging to manage due to high vascularity and proximity to critical structures. Two patients with large, symptomatic thoracic ABCs are presented.

Observations: Preoperative tumor embolization via pedicle artery sacrifice was performed prior to planned resection to reduce intraoperative blood loss and the risk of postoperative neurological deficits.

Article Synopsis
  • The retinogeniculate visual pathway (RGVP) transmits visual data from the retina to the brain, making its identification crucial for understanding vision-related conditions.
  • DeepRGVP, a new deep learning framework, allows efficient and precise mapping of the RGVP from diffusion MRI data, overcoming the challenges of manual tract selection.
  • Experiments demonstrate DeepRGVP's superior accuracy in identifying the RGVP compared to existing methods, even in patients with lesions, highlighting the promise of deep learning in improving visual pathway analysis.

Article Synopsis
  • The retinogeniculate visual pathway (RGVP) transmits visual information from the retina to the brain, and understanding its anatomy is crucial for studying visual system diseases.
  • Diffusion MRI (dMRI) tractography is a technique for mapping the RGVP, but current methods for identifying it are slow and subjective, relying on manual expert input.
  • This paper introduces a deep learning framework called DeepRGVP, which uses advanced techniques to quickly and accurately identify the RGVP from dMRI data while maintaining effectiveness even in cases of brain lesions, demonstrating the promise of AI in medical imaging.

Cerebral proliferative angiopathy (CPA) is an entity distinct from that of classical arteriovenous malformations. As such, few reports have considered the long-term follow-up of patients with hemorrhage in CPA. Accordingly, herein the authors present a case of recurrent hemorrhage in CPA with 32 years of follow-up and in so doing summarize the literature of hemorrhagic cases in CPA.

Article Synopsis
  • Diffusion magnetic resonance imaging white matter tractography helps plan brain surgeries by aiming to excise tumors while preserving brain function, but faces challenges due to limitations in standard imaging techniques.
  • Track density imaging (TDI) offers enhanced visualization of brain connections over traditional diffusion tensor imaging (DTI), potentially improving surgical planning.
  • This study compared TDI-based maps to DTI-based maps using patient data, with five neurosurgeons evaluating their utility in pre-surgical planning.

Background: Herpes simplex virus (HSV) is a common cause of viral encephalitis and can result in refractory seizures. Although HSV encephalitis (HSVE) is treated primarily with acyclovir, surgery can play a role in medically intractable cases.

Objective: To systematically review cases describing surgery for the treatment of severe HSVE.

Article Synopsis
  • The study reviews global cancer surgery literature since a key report in 2015, focusing on articles from low-resource countries.
  • It performs a SWOT analysis identifying themes such as local research, resource limitations, and the impact of COVID-19 on surgical care.
  • The findings aim to offer strategies to improve cancer surgery in underserved areas while addressing significant challenges and opportunities in the field.

Article Synopsis
  • - The case study presents a 74-year-old man with severe essential tremor and diffuse skull thickening (hyperostosis), who did not improve after undergoing magnetic resonance-guided focused ultrasound (MRgFUS) treatment.
  • - Pre-treatment imaging indicated a low skull density ratio (SDR) and the presence of tricortical hyperostosis, yet post-treatment MRI showed no changes or lesions.
  • - A literature review revealed that out of three similar cases of patients with hyperostosis, all also failed MRgFUS treatment, suggesting that tricortical hyperostosis may be a contraindication for this therapeutic approach.

Objectives: Stereotactic radiosurgery (SRS) is part of the multimodality treatment for patients with cancer. The objective of this study is to determine factors which influence overall survival (OS) of Filipino patients who underwent SRS for metastatic tumors of the spine.

Methods: This is a retrospective analysis of a cohort of Filipino patients treated with spine SRS for metastatic tumors in a single institution.

Spontaneous intracranial hypotension (SIH) still remains an underdiagnosed etiology of new-onset headache. Important risk factors include chiropractic manipulation (CM). We present a case of a 36-year-old Filipino woman who presented with severe bifrontal and postural headache associated with dizziness, vomiting, and doubling of vision.

Introduction: Mild cognitive impairment (MCI) is a dynamic state, which has evolved into a highly defined condition due to its association with dementia syndromes. There are no published data on the demographic and clinical characteristics of MCI in the Philippines. These data will help in defining the population at risk for the condition and in modifying the factors for its prevention.

Objectives: The objectives of this paper are to describe pain control, neurologic improvement, local tumor control, progression-free survival, and overall survival of spine SRS/SFRT patients, and to compare our outcomes with other studies on spine stereotactic radiotherapy for metastatic tumors.

Methods: A chart review of patients who underwent spine SRS/SFRT was done. Information was collected on patient age, sex, histology, site treated, pain relief, local control, neurologic function, prescription dose, and complications.
