RESUMO
BACKGROUND: Increased blood pressure (BP) variability may worsen the prognosis of stroke. This study aimed at investigating the association between BP variability and early functional prognosis in patients with pontine infarction. METHODS: According to types of pontine infarction, all the 137 patients were divided into two groups: 70 patients with paramedian pontine infarction (PPI) and 67 patients with deep pontine infarction (DPI). Common risk factors, 24-hour continuous blood pressure monitoring data, and the coefficient of variation were collected after admission in the hospital. Functional outcomes were evaluated with modified Rankin scale (mRS) at 3 months after discharge (favorable outcome: mRS scores ≤ 2; poor outcome: mRS scores > 2). RESULTS: The level of Glu, HbA1c, LDL, and NIHSS scores in the PPI group was significantly higher than that in the DPI group, and the concentration of blood uric acid was lower in the PPI group. Diastolic pressure in the PPI group is significantly higher than that in the DPI group, and coefficient of variation (CV) of systolic pressure in PPI is higher when compared with DPI ((88.77 ± 1.71) mmHg vs. (80.74 ± 1.31) mmHg; (11.54 ± 0.35) vs. (10.24 ± 0.25)). In multivariate analyses, the CV of systolic pressure, diastolic pressure, NIHSS scores, and the paramedian pontine infarction was independently associated with 3-month clinical outcome (OR = 1.94, 95% CI = 1.252-2.994, P=0.003; OR = 1.08, 95% CI = 1.002-1.166, P=0.04; OR = 1.58, 95% CI = 1.164-2.159, P=0.003; OR = 9.87, 95% CI = 1.045-32.193, P=0.04). CONCLUSION: In conclusion, increased 24-hour (BP) variability, NIHSS scores, and paramedian pontine were associated with early poor prognosis in patients with acute pontine infarction.
RESUMO
BACKGROUND: This study aims to analyze the clinical, imaging, electrophysiological, and dermatopathological features of a patient with adult-onset neuronal intranuclear inclusion disease (NIID) and to explore the diagnostic methods of adult-onset NIID. CASE PRESENTATION: We here report a 63-year-old male with recurrent acute encephalopathy syndrome and autonomic nervous system damage syndrome characterized by sexual dysfunction and urinary and fecal dysfunction. Cranial diffusion-weighted magnetic resonance imaging (DWI) demonstrated symmetrically distributed strip-shaped high-intensity signal in bilateral fronto-occipital-parietal cortical-medullary junction. Electrophysiological test revealed that the main site of injury was myelin sheath in both motor and sensory nerves. Skin biopsy revealed eosinophilic spherical inclusion bodies in the nucleus of sweat gland epithelial cells. CONCLUSION: This case suggests that adult NIID is a chronic neurodegenerative disease with high clinical heterogeneity. Subcortical strip-shaped high-intensity signal on DWI has high diagnostic significance. Eosinophilic intranuclear inclusion bodies detected by skin biopsy contribute to diagnosis.
