RESUMO
Spontaneous intracerebral hemorrhage commonly affects the brainstem. This report describes a 31-year-old male with hypertension who developed a pontine hemorrhage. The neurological deficits included left-third nerve palsy, right-sided weakness, and disabling tinnitus. Tinnitus is linked to central auditory pathway disruption. Magnetic resonance imaging revealed the hemorrhagic lesion and additional micro-hemorrhages. The International Classification of Functioning, Disability, and Health (ICF) enhances rehabilitation by characterizing multifaceted stroke disability. The ICF profile revealed impairments in body structures/functions, limitations in activities/participation, and positive/negative environmental factors. ICF-based goal-setting informed interventions, including tinnitus retraining and physical/occupational therapy. Comprehensive ICF assessment is crucial for optimized, patient-centered post-stroke rehabilitation as it determines the extent of impact on functional level of the patient irrespective of disease severity.
RESUMO
The spectrum of COVID-19 infection includes acute respiratory distress syndrome (ARDS) and macrophage activation syndrome (MAS), although the histological basis for these disorders has not been thoroughly explored. Post-mortem pulmonary and bone marrow biopsies were performed in 33 patients. Samples were studied with a combination of morphological and immunohistochemical techniques. Bone marrow studies were also performed in three living patients. Bone marrow post-mortem studies showed striking lesions of histiocytic hyperplasia with hemophagocytosis (HHH) in most (16/17) cases. This was also observed in three alive patients, where it mimicked the changes observed in hemophagocytic histiocytosis. Pulmonary changes included a combination of diffuse alveolar damage with fibrinous microthrombi predominantly involving small vessels, in particular the alveolar capillary. These findings were associated with the analytical and clinical symptoms, which helps us understand the respiratory insufficiency and reveal the histological substrate for the macrophage activation syndrome-like exhibited by these patients. Our results confirm that COVID-19 infection triggers a systemic immune-inflammatory disease and allow specific therapies to be proposed.
