Background: Although brain tumor is a common neurosurgical condition, diagnosis is generally made after long duration of symptoms. This may have negative impact on treatment outcome.
Objective: Study the duration of symptoms of brain tumor, how it is influenced by various factors, and find their value in predicting malignant tumors.
Material And Method: The authors retrospectively reviewed 185 patients with pathologically proven brain tumors. Pertinent data including age, types of tumors, locations of tumors, symptoms, and duration of symptoms were analyzed by univariate and multivariate analysis.
Results: There were 70 males and 115 females. The mean age at diagnosis was 47.3 years. The average duration of symptoms was 471 days with median of 120 days. On univariate analysis, hormone symptoms (p = 0.001), age more than 45 years old (p = 0.005), malignant tumor (p < 0.001), auditory symptoms (p = 0.004), and motor symptoms (p < 0.001) had significant influence on duration of symptom. In multivariate analyses, malignant types of tumor, age, and hormonal symptoms were significant. In addition, there was higher risk of malignant brain tumor in patients with duration of symptoms 1 month or less (p < 0.001).
Conclusion: Certain factors were associated with longer duration of symptoms in brain tumors. This information may lead to early diagnosis of brain tumors. Furthermore, duration ofsymptoms of 1 month or less was suggestive of malignant brain tumors.

Apolipoprotein E (ApoE), especially the ApoE4 isotype, is suggested to influence the severity of respiratory viral infections; however, this association is still unclear. The presence of allele ε4 impacts the development of flu-like syndromes. This study aimed to evaluate the impact of the Apo E4 isoform on the severity and duration of flu-like syndromes, including the coronavirus disease COVID-19.

Objective: The aim of this work is to demonstrate how the chronicity of low back pain can modify the trophism of the paraspinal muscles, by performing an ultrasound and MRI evaluation of the paraspinal muscles in the lumbar spine and correlating it to the time of onset of low back pain.
Materials And Methods: An ultrasound evaluation was carried out in the lumbar area with a 5-17 MHz linear probe of the paraspinal muscles of the lumbar region, compared with the MRI of the lumbar spine, in patients presented to our attention for chronic low back pain (> 6 months), from January 2021 to January 2023. In each patient, two series of images were analyzed, in the coronal and sagittal planes.
