Acute Subdural Hemorrhage as the Initial Presentation of Intracranial Hypotension Following Cervical Chiropractic Manipulation: A Case Report and Systematic Review.

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. A cranial computed tomography scan was done which showed an acute subdural hematoma (SDH) at the interhemispheric area. Pain medications were given which afforded minimal relief. On history, the headaches occurred 2 weeks after cervical CM. Cranial and cervical magnetic resonance imaging revealed findings supportive of intracranial hypotension and neck trauma, respectively. The patient improved with conservative management. We found 12 articles on SIH and CM after a systematic review of literature. Eleven patients (90.9%) initially presented with orthostatic headache. Eight patients (66.7%) were initially treated conservatively but only 5 (62.5%) had complete recovery. Recovery was achieved within 14 days from start of supportive therapy. Among the 3 patients who failed conservative treatment, 2 underwent non-directed epidural blood patch and one required neurosurgical intervention. This report highlights that a thorough history is warranted in patients with new onset headache. A history of CM must be actively sought. The limited evidence from the case reports showed that patients with SIH and SDH but with normal neurologic examination and minor spinal pathology can be managed conservatively for less than 2 weeks. This review showed that conservative treatment in a closely monitored environment may be an appropriate first line treatment.

Acute stroke care algorithm in a private tertiary hospital in the Philippines during the COVID-19 pandemic: A third world country experience.

BACKGROUND AND PURPOSE: Since the declaration of the Novel Coronavirus Disease (COVID-19) pandemic, ensuring the safety of our medical team while delivering timely management has been a challenge. Acute stroke patients continue to present to the emergency department and they may not have the usual symptoms of COVID-19 infection. Stroke team response and management must be done within the shortest possible time to minimize worsening of the functional outcome without compromising safety of the medical team. METHODS: Infection control recommendations, emergency department protocols and stroke response pathways utilized prior to the COVID 19 pandemic within our institution were evaluated by our stroke team in collaboration with the multidisciplinary healthcare services. Challenges during the COVID-19 scenario were identified, from which a revised acute stroke care algorithm was formulated to adapt to this pandemic. RESULTS: We formulated an algorithm that incorporates practices from internationally devised protocols while tailoring certain aspects to suit the available resources in our system locally. We highlighted the significance of the following: team role designation, coordination among different subspecialties and departments, proper use of personal protective equipment and resources, and telemedicine use during this pandemic. CONCLUSIONS: This pandemic has shaped the stroke team's approach in the management of acute stroke patients. Our algorithm ensures proper resource management while optimizing acute stroke care during the COVID-19 pandemic in our local setting. This algorithm may be utilized and adapted for local practice and other third world countries who face similar constraints.

Gamma knife radiosurgery and brain metastases: local control, survival, and quality of life.

OBJECT: The purpose of this paper was to describe the clinical outcome in patients with brain metastases who underwent gamma knife radiosurgery (GKS). METHODS: The authors retrospectively reviewed the clinical courses of 54 patients with brain metastases who underwent 62 GKS procedures. This series covered a 43-month period. A total of 174 lesions were treated: 38 patients harbored solitary whereas 24 patients harbored multiple metastases. The authors assessed outcome by examining local disease control, survival, and quality of life. The overall local control rate was 85%; the mean time to failure of local control was 10.5 months; and median survival was 8.4 months. Median survival, evaluated by the log-rank test, was greater among patients with a single metastasis (p = 0.043), breast cancer (p = 0.021), and those who had undergone multiple GKS procedures for local failure (p = 0.009). The initial Karnofsky Performance Scale (KPS) score and whole-brain radiotherapy were not significantly related to median survival. The KPS scores tended to remain stable through the follow-up period. There were no morbidities or deaths attributable to the procedure. CONCLUSIONS: Results in this series suggest that GKS can be an effective tool for the control of brain metastases. A prospective investigation should be performed to validate trends seen in this retrospective study.
