Objective To observe the initial therapy outcomes of Valproic acid for childhood absence epilepsy (CAE),and to assess its therapeutic reaction and short-term prognosis,and to investigate the risk factors for initial therapy failure.Methods From January 2010 to December 2015,absence seizures as key words were used to search CAE in the video-electroencephalogram(VEEG) database of Children's Hospital Affiliated to Nanjing Medical University.Sixty-seven children fulfilled the CAE diagnosis criteria of International League Against Epilepsy in 1989.These patients were separated into 2 groups based on the therapy outcome after 6 months,including seizure control failure group and seizure control group.The patients' clinical characteristics and VEEG characteristics were reviewed.The gender,age of seizure onset,a family history of epilepsy or febrile seizures (FS),consistent with 2005 Panayiotopoulos diagnostic criteria,and VEEG findings were analyzed to evaluate the predictive ability of independent variables and the relationship between these features and treatment outcomes by using a stepwise multivariate Logistic regression model.Results The age at seizure onset was (5.89 ± 2.91) years old,and follow up duration was 6 months.Approximately 23 cases (34.3%) of CAE patients had poor response.No statistical correlation was made for gender,age at onset,the occurrence of generalized tonic clonic seizures,and family history of FS or epilepsy between 2 groups (all P >0.05).Compared with seizure control group,patients of the seizure control failure group had significantly higher rates of focal epileptic discharge (87.0% vs.6.8%),higher rates of intermittent photic stimulation (IPS) induced seizures (52.2% vs.6.8 %),fewer rates of occipital intermittent delta activity (8.7 % vs.77.3 %),and fewer rates of patients met the new diagnostic criteria proposed by Panayiotopoulos in 2005 (8.7% vs.88.6%) (all P < 0.001).The presence of occipital intermittent rhythmic delta activity during wake stage and the interictal focal epileptiform discharges on VEEG during sleep stage were significantly associated with the therapy outcomes in a multivariable Logistic regression analysis (OR =133.714,P < 0.05;OR =0.068,P < 0.05).Conclusions The presence of focal epileptiform discharges,and a typical absence induced by IPS are important factors for first-drug treatment failures with CAE,and conversely the occipital intermittent rhythmic delta activities have a good efficacy.There is no statistical correlation between clinical characteristics and treatment outcomes.

Objective:To evaluate the value of ultrasound-guided transperineal systematic prostate biopsy(SPB)and cognitive fusion multi-parameter magnetic resonance imaging(mpMRI) suspicious transperineal targeted biopsy(CFTB) in the prostate cancer with different serum prostate specific antigen(PSA) levels.Methods:A retrospective analyses were performed in 527 patients with suspected prostate cancer who underwent ultrasound-guided SPB from January 2018 to December 2019 in Shanghai Jiaotong University Affiliated 6th People′s Hospital. According to the PSA levels, they were divided into group A(PSA 4-10 μg/L) and group B(PSA>10 μg/L). All the patients underwent ultrasound-guided SPB, 376 patients with suspicious mpMRI had two additional targeted biopsies. The detection rates of ultrasound-guided SPB and CFTB in prostate cancer were tested by χ 2 test. Compared with pathological results, the sensitivity, specificity, accuracy of two methods were calculated and tested by χ 2 test, and a P<0.05 was defined as statistically significant difference. Results:Prostate cancer was detected in 319 of 527 patients(60.5%). One hundred and three cases of 198 patients in group A were diagnosed as prostate cancer, with an overall detection rate was 52.0%. Among them, ultrasound-guided SPB detected 72 cases of prostate cancer, the detection rate was 36.4%, sensitivity was 67.9%, specificity was 17.7%, accuracy was 26.5%, the detection rate, sensitivity, specificity and accuracy of CFTB were 39.9%, 75.6%, 91.6% and 88.8%, respectively. In this group, there were no statistically significant differences in the detection rate and sensitivity of the two methods in the diagnosis of prostate cancer (χ 2=0.525, 0.005, both P>0.05), and the differences in specificity and accuracy were statistically significant (χ 2=108.340, 79.829, respectively, both P<0.05). Two hundred and sixteen cases of 329 patients in group B were diagnosed as prostate cancer, with an overall detection rate was 65.7%. Among them, 160 cases of perineal prostate cancer were detected by ultrasound-guided SPB, with the detection rate was 48.6%, sensitivity was 78.2%, specificity was 37.6% and accuracy was 49.5%. A total of 189 cases of prostate cancer detected by CFTB, the detection rate was 57.4%, the sensitivity was 89.3%, the specificity was 90.6%, and the accuracy was 90.2%. All the differences were statistically significant in group B(χ 2=5.131, 4.391, 61.339, 38.982, all P<0.05). Conclusions:When PSA is greater than 10 μg/L, CFTB has a higher diagnostic efficiency than SPB.When PSA is 4-10 μg/L, there are no significant differences between the two methods in the detection rate and sensitivity of prostate cancer.

Purpose To study the clinic-pathologic features, differential diagnosis and prognosis of lymphoepithelioma-like carcinoma of cervix. Methods Eight cases of lymphoepithelioma-like carcinoma of cervix were retrieved from our institution. HE staining, im-munohistochemistry and in situ hybridization were perform on those cases. Results Of the 8 cases of lymphoepithelioma-like carcino-ma,the median age was 44 years old ( ranged from 29-67 years) and all of the clinical stage belonged toⅠB. Grossly, 5 cases presen-ted a cauliflower-like appearance, 1 case grew as a polyp protrusion, and the other 2 cases showed a non-specified thicken change of cervix. Histologically, the tumors were composed of undifferentiated large cells, either loosely or closely-packed, with the nested and trabecular growth pattern. The tumor cells were generally oval or polygonal in shape, while the demarcation between the cells was indis-tinct and form the syncytial appearance. The nuclei were vesicular and had one or more prominent nucleoli. There were abundant infil-trates of lymphocyte and plasma cells among the tumor nests. The tumor cells showed positive expression of CK in 100% of cases, p63 in 37. 5% of cases, p16 in 62. 5% of cases, CK5/6 in 75% of cases, Ki-67 in 10% ~30% of cases. The stromal lymphocytes mainly expressed CD3 and CD8. EBER was negative in the entire tumor cells while was weakly positive in the stromal lymphocytes in one case. The follow-up data, which terminated at June 2013, demonstrate 7 cases were alive and 1 case died of the disease. Conclusions Lymphoepithelioma-like carcinoma occurred of cervix is rare. They have distinctive morphologic features and overall favorable prog-nosis. The accurate diagnosis is dependant on the combination of the histologic and immunohistochemical examination.
