Subependymal giant cell astrocytoma is a rare tumor that occurs in the walls of the lateral ventricles, foramen of Monro, and less frequently, in the third ventricle. It is one of the intracranial lesions found in tuberous sclerosis complex (TSC) ─ a rare multisystem genetic disease. We present a rare case of an adult Filipino with cutaneous signs of TSC, who initially presented with signs of increased intracranial pressure. The patient underwent right frontal craniotomy, endoport-assisted excision of the tumor with insertion of a ventriculoperitoneal (VP) shunt. Histopathology was consistent with a subependymal giant-cell astrocytoma WHO grade 1. The general status of the patient improved thereafter – there was the relief of headache and improvement in vision and gross hearing. Subependymal giant cell astrocytoma is a rare tumor of the central nervous system especially in adults, whose diagnosis is based on clinical, radiological, and histological, and immunohistochemical stains. It should be included in the differential diagnosis of a mass near the foramen of Monro. Given the hereditary nature of the disease, genetic counseling is essential when encountering patients with this condition.

Objective: The study aimed to investigate the relationship between cardiac Troponin I (cTnI) level and prognosis among mechanically ventilated patients in terms of mortality, prolonged mechanical ventilation, and tracheostomy rate. Methods: This is a prospective cohort study conducted at Quirino Memorial Medical Center, a tertiary government hospital, over a period of ten (10) months. Seventy-six (76) mechanically ventilated adult patients admitted at the medical intensive care unit, surgical intensive care unit, medical wards, and centers for neurologic sciences were included in the study. Quantitative cardiac Troponin I (cTnI) marker was measured and correlated to prognostic outcomes: a) prolonged ventilation (requiring more than 21 days), b) tracheostomy rate, and c) mortality rate. Data were analyzed using SPSS 16.0 and logistics regression with 95% confidence interval. Results: Results showed that among 76 patients, 15 patients have low cTnI levels, 11 patients have normal levels and 50 patients have elevated levels. Among patients with low cTnI levels (<0.020 ng/mL), 13 (86.7%) were extubated, 1 (6.7%) preceded tracheostomy and 1 (6.7%) expired. Those with normal range cTnI levels (0.020 – 0.060 ng/mL), 10 (90.9%) were extubated, none (0%) preceded tracheostomy and 1 (9.1%) expired. Those with elevated cTnI levels (>0.060 ng/mL), 7 (14.0%) were extubated, 7 (14.0%) preceded tracheostomy and 36 (72.0%) expired. Conclusion Analysis of the results showed a significant correlation of cTnI elevation with prognostic outcome proven by the p-value of < 0.0001. The risk of mortality among subjects with above normal cTnI levels were nine times (9x) higher compared to subjects with normal or low cTnI levels. Duration of intubation among patients with low normal and high cTnI levels did not differ significantly. Tracheostomy rate in the study was inconclusive.
