Comparison of temporal lobe epilepsy with hippocampal sclerosis and temporal lobe epilepsies due to other etiologies.
BACKGROUND: This study compares the clinical characteristics of patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS) with those who have temporal lobe epilepsy (TLE) due to other etiologies.
METHODS: In this retrospective study all patients with a clinical diagnosis of TLE were recruited in a referral outpatient epilepsy clinic at Shiraz University of Medical Sciences from September 2008 to May 2013. We classified the patients with TLE as having mesial temporal sclerosis if they had clear signs of mesial temporal sclerosis and/or atrophy in their MRI and others who had any other MRI abnormality.
RESULTS: A total of 174 patients were studied (including 105 patients with mTLE-HS and 69 patients with TLE due to other etiologies). Frequency of seizure types was not significantly different between these two groups. Earlier age at epilepsy onset (p= 0.005), a past history of febrile seizures (p= 0.010) and presence of affective auras (p= 0.008) were commonly seen in patients with mTLEHS, while auditory auras (p= 0.020) were more frequent in those with TLE due to other etiologies.
CONCLUSION: The mainstay for making a correct diagnosis, when evaluating a patient with seizure, is having a standardized approach, particularly with regard to taking a detailed clinical history. One may find important clues in the clinical history (e.g., age at disease onset, detailed seizure description and past history) to make a correct diagnosis
T-helper Type 1 and 2 Cytokine Levels in Patients with Benign and Malignant Salivary Gland Tumors
ABSTRACT Background: Salivary gland tumors are among malignancies that have high recurrence rate. Immune responses in salivary gland tumors have not been well elucidated. T helper type 1 (Th1) and Th2 cytokines have been reported to play a role in the outcome of head and neck cancers. Objective: To evaluate the serum levels of interferon gamma (IFN-γ), as the hallmark of Th1 cytokines, and interleukin-4 (IL-4), as the hallmark of Th2 cytokines, in patients with benign and malignant salivary gland tumors in comparison with healthy controls. Methods: Fifty patients with benign and 14 patients with malignant salivary gland tumors, as well as 23 healthy individuals were recruited. Serum levels of IFN-γ and IL-4 were measured using ELISA method. Nonparametric tests were used for data analysis. Results: Serum levels of IFN-γ and IL-4 were found not to be significantly different in patients compared to the control group (0.68 ± 0.29 vs. 1.03 ± 0.57 pg/ml, p=0.58 for IFN-γ, 4.57 ± 1.57 vs. 4.41 ± 1.31 pg/ml, p=0.28 for IL-4). IFN-γ and IL-4 serum levels were also not significantly different between patients with benign and malignant salivary gland tumors (p=0.54 and p=0.86, respectively). Conclusion: The systemic levels of IL-4 and IFN-γ seem not to be associated with salivary gland tumor in our study. Investigation of other cytokines produced by Th1 and Th2 cells are warranted
