Hereditary neuropathy with liability to pressure palsies misdiagnosed as Guillain-Barré Syndrome: A case report.

RATIONALE: Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal dominantly inherited genetic disease characterized by recurrent numbness and limb weakness. HNPP can be easily missed or misdiagnosed because of electrophysiological heterogeneity and atypical clinical symptoms. To date, diagnosis of HNPP remains a challenge for clinicians. PATIENT CONCERNS: Here, we report the case of a 12-year-old woman diagnosed with HNPP, which was initially diagnosed with Guillain-Barré Syndrome (GBS) and treated with intravenous immunoglobulin (IVIG). DIAGNOSES: Repeat electrodiagnostic studies and genetic testing confirmed the diagnosis of HNPP. INTERVENTIONS: The patient was treated with neurotrophic drugs and health education, including avoiding maintenance of a certain posture for extended periods, which could damage the peripheral nerves. OUTCOMES: The patient was discharged 5 days later. The patient was free from recurrence after 6 months of follow-up. LESSONS: This case highlights the complexity of HNPP diagnosis and emphasizes the importance of early identification.

L-3-n-butylphthalide promotes restoration after an experimental animal model of intracerebral hemorrhage.

Intracerebral hemorrhage (ICH) is a devastating type of stroke with high morbidity and mortality, and the effective therapies for ICH remain to be explored. L-3-n-butylphthalide (NBP) is widely used in the treatment of ischemic stroke. However, few studies evaluated the therapeutic effects of NBP on ICH. Therefore, the present study aims to evaluate the effects of NBP on ICH and its potential mechanism. The rats were randomly divided into sham-operated group, saline-treated (ICH + saline) group, and NBP-treated (ICH + NBP) group. The ICH model of SD rats induced by IV collagenase was established. The modified Garcia JH score was used to detect the neurological deficit in rats. Western Blot and immunohistochemistry analysis was applied to test the levels of UBIAD1 and caspase-3 expressions in the perihematomal region. The rates of apoptotic cells were detected by TUNEL staining. The results showed that NBP up-regulated the expression of UBIAD1, reduced the apoptotic cells in the perihematomal region, and improved the neurological deficit. Taken together, our study added some new evidence to the application of NBP in ICH treatment.
