Background: Tetanus is a life-threatening but preventable neurologic disorder characterized by trismus and muscle spasms. Despite its decreasing global incidence, it remains to be endemic in resource-limited settings such as the Philippines. This study aimed to determine the incidence, demographic characteristics, risk factors, clinical presentation, management, complications, and outcomes of non-neonatal tetanus cases in a tertiary hospital in the Philippines. It also aimed to compare the clinical profile and outcomes between the adult and pediatric subgroups. Methods: This study used a retrospective cross-sectional design including all adult and pediatric non-neonatal tetanus patients admitted at the University of the Philippines - Philippine General Hospital from January 2012 to June 2023. Data was extracted from department censuses and inpatient charts. Results: One hundred thirty-eight cases were included. The incidence rate was 0.03%, while mortality rate was 29%. Majority of patients were males presenting with trismus and spasms after sustaining a puncture wound. Chronic hypertension was associated with an increased hazard of death by 4.5 times (p = 0.004), while treatment with magnesium sulfate was associated with a decreased hazard of death by 35 times (p = 0.005). The mode of infection and the medications administered differed between the adult and pediatric subgroups. Conclusions: Although the total number of cases has decreased over the past decade, tetanus remains to have a high incidence and mortality rate in the Philippines. Increasing vaccination coverage, improving public awareness, and educating health professionals can help reduce morbidity and mortality from this disease.

The COVID-19 pandemic has led to a rise in cases of Guillain-Barré syndrome (GBS). This autoimmune sequela is a manifestation of the neurotropism potential of the virus. At present, knowledge regarding the pathophysiology, clinical features, management and outcomes of the condition is still evolving. This paper presents the case of a 22-year-old pregnant patient who came in with a history of upper respiratory tract symptoms followed by acroparaesthesia and progressive ascending weakness. She was confirmed to have COVID-19 and GBS and was subsequently managed with intravenous immunoglobulin (IVIg) followed by supportive therapy. To the authors’ knowledge and based on their literature search, this is the first reported case of GBS in a COVID-19 confirmed pregnant patient who received IVIg.

The diagnosis of healthcare-associated ventriculitis and meningitis (HCAVM) can be complex because multiple factors confound the interpretation of cerebrospinal fluid (CSF) tests. The cell index (CI) may help in the diagnosis of HCAVM. It does not incur additional medical cost and it avoids delays from the turnaround time of CSF cultures. It is derived by calculating the ratio of CSF white blood cell (WBC) and red blood cell (RBC) divided by the ratio of peripheral WBC and RBC. This study aimed to evaluate the diagnostic utility of this parameter. An analytic, observational, cross-sectional study was conducted at the University of the Philippines – Philippine General Hospital. All admitted pediatric and adult patients from 2015 to 2022 who underwent external ventricular drain (EVD) insertion for hydrocephalus secondary to intracranial hemorrhage (ICH), acute ischemic stroke, intracranial neoplasms, traumatic brain injury, or congenital hydrocephalus were screened. Records of patients fulfilling the inclusion criteria were then reviewed. A total of 363 patients underwent EVD insertion from 2015 to 2022. Of these, 161 were included in the study. Two-thirds (66.5%) were adults ≥ 19 years old whereas the remaining were pediatric patients 1 to < 19 years old. There were no patients < 12 months old as they fulfilled at least one exclusion criteria. Forty-nine of them were later confirmed to have HCAVM based on the CDC/NHSN criteria. A CI cut-off of ≥ 1.21 gave a maximum sensitivity of 30.6% and specificity of 86.4%. Receiver operating characteristic area under the curve (AUC-ROC) analysis was 0.585. Subgroup analysis by age showed sensitivity of 52.9% in the pediatric age group and 3.13% in adults. Subgroup analysis by neurologic indication showed sensitivity of 27.6% for ICH and 35.0% for neoplasms. Subsequent AUC-ROC analyses, however, showed that CI failed to adequately diagnose HCAVM in these subgroups. In our population of neurologic patients who underwent EVD insertion, the cell index is not a reliable parameter in the diagnosis of HCAVM.

Background: Acute to subacute pediatric movement disorders require prompt diagnosis to identify potentially treatable diseases. Case Report: We present a 6-year-old male with a three-week history of generalized chorea transitioning to predominantly right-sided hemichorea and then to left hemiplegia. Discussion: We review the mechanisms in tuberculous meningitis underlying his movement abnormalities.

Cancer-associated stroke is an evolving subgroup of embolic strokes of undetermined source. A man in his mid-20s with progressive follicular variant acinic cell carcinoma of the parotid was admitted because of new onset left-sided weakness. Neuroimaging confirmed a right middle cerebral artery infarction. After extensive diagnostics, stroke aetiology was deemed from cancer-induced hypercoagulability. Questions which arose regarding his management included (1) What was the best antithrombotic for secondary stroke prevention? (2) What was his risk for intracranial or tumorous bleeding once antithrombotics had been started? (3) How many days post-stroke could the antithrombotic be initiated? and (4) When could he be cleared for palliative chemotherapy and whole brain irradiation? The approach to address the abovementioned questions in the management of a rare cancer complicated by stroke is presented. Although treatments are guided by known pathomechanisms, additional studies are needed to further support current treatment strategies for this subgroup of patients.

Angiostrongylus cantonensis is the leading parasitic cause of eosinophilic meningitis but there have been no cases of human infection reported from the Philippines. We report a 25-year-old female, with a dietary preference for raw lettuce, who presented with a two-week history of low-grade fever, malaise, progressive holocranial headache, and myalgia. She had Grade 2 papilledema, nuchal catch, and peripheral eosinophilia. Lumbar puncture eventually revealed eosinophilic meningitis. Extensive diagnostics were completed to exclude all potential infectious, hematologic, and rheumatologic causes of central and peripheral eosinophilia eventually leading to the conclusion of Probable Neuroangiostrongyliasis. She was managed conservatively until discharge and remained headache-free one year later. This case highlights important challenges in the diagnosis and management of this extremely rare zoonosis in the Philippine setting and demonstrates the need for increased public and medical awareness regarding this condition.
