Photosensitive occipital lobe epilepsy (POLE) is a rare idiopathic reflex focal epilepsy that can occur in all age groups. It is characterized by occipital lobe seizures induced by flashing stimuli (flashing sunlight, video games, TV commercials and programs, etc.). Photoparoxysmal response on EEG is induced by intermittent photic stimulation; Ictal EEG shows rapid spike rhythms are originated from the occipital region. There are no obvious abnormalities in brain image. POLE responds well to anti-seizure medications and has a good prognosis. This article reviews the research progress on POLE in order to improve the clinician’s understanding and reduce the rates of missed diagnosis and misdiagnosis.
Objective To investigate HCV genotypes in HCV patients in West China Hospital of Sichuan University, and to analyze the major genotypes and clinical characteristics. Methods From March 2011 to September 2016, 4 520 HCV patients who were successfully genotyped HCV genotypes were enrolled in West China Hospital of Sichuan University. The genotypes distributions and the characteristics of laboratory characteristics of liver function, the viral loading were all analyzed. In addition, the genotypes in HCC patients, liver cirrhosis, HBC/HCV co-infection were also analyzed. Results HCV genotypes of HCV patients were divided into five genotypes of 1, 2, 3, 4, 6 and 23 subtypes, including predominant genotypes/subtypes 1b, 1*, 3b, 2a, 3a and 6a, accounting for 66.42%, 8.01%, 6.57%, 4.54%, 4.29%, and 3.41%, respectively. Subtype 1b was the predominant subtype for both sex. In male patients, the levels of ALT were highest in 6a subtype, while in female, the levels of ALT were highest in 3a subtype. For the 94 liver cirrhosis patients, 42 patients were 1b subtypes; as for the 6 HCC patients, 1b and 3b subtypes were the only detected. Conclusion HCV genotypes/subtypes of HCV patients in West China Hospital of Sichuan University have unique characteristics of distribution, while the predominant genotype/subtypes are 1b,1*, 3b, 2a, 3a, 6a.
Objective To investigate HPV infection, genotype distribution of HPV infection among 8 944 females of health examination in West China Hospital of Sichuan University. Methods We enrolled 8 944 females of health examination in West China Hospital of Sichuan University from January to September in 2016. HPV genotyping was performed by Luminex fluorescence technique. Excel 2007 and SPSS 17.0 softwares were used to analyze the infection and genotype distribution of HPV. Results The HPV infection rate of 8 944 health examination women was 14.4% (1 291/8 944). Among them, there were 1 025 cases of single infection, the infection rate was 11.5% (1 025/8 944); there were 266 cases of multiple infection, the infection rate was 3.0% (266/8 944). The infection rates of 20 to 25 years and ≥66 years groups in single and multiple infection were higher than other age groups. In the single and multiple infections, the most common genotypes were HPV52, 53, 16 and 58. Infection rate of HPV52 was the highest in single infection, which had two increased age groups including 31 to 35 years and 61 to 65 years old. Infection rate of HPV52 and HPV16 were increased in 20 to 25 years old group of multiple infections. Conclusion In view of the prevalence of HPV infection among health examination females and the genotype distribution, we recommend incorporating HPV52, 53 and 58 into future vaccine screening.
