ObjectiveTo compare the efficacy and safety of perampanel (PER) and oxcarbazepine (OXC) monotherapy in the treatment of newly diagnosed focal epilepsy in adults. Methods A total of 62 adult patients with focal epilepsy, aged 18~79 years old, with an average age of (40.53±16.69) years, were enrolled from Qingyuan People’s Hospital between August 2021 and October 2022 and randomly divided into PER group and OXC groups. Both groups were followed up for 12 months and assessed for seizure free rate, effective rate, drug retention rate, and adverse reactions at 3, 6, and 12th months. ResultsThe results showed that the seizure free rate, effective rate, and drug retention rate in the PER group were 62.5%, 71.9% and 87.5% at 3 months, respectively, and 53.1%, 65.6% and 75.0% at 6 months respectively. In the OXC group, the seizure free rate, effective rate, and drug retention rate were 70.0%, 86.7%, and 93.3% at 3 months, respectively, and 66.7%, 73.3% and 83.3% at 6 months, respectively. At 12 months, the seizure free rate, effective rate and retention rate of the PER group were 43.8%, 46.9%, and 53.1%, respectively; The seizure free rate, effective rate, and retention rate of OXC group were 66.7%, 66.7%, and 70.0%, respectively. The incidence of adverse reactions in the PER group and OXC group was 15.6% and 16.7%, respectively. The most common adverse reactions in both groups were dizziness and drowsiness, with no serious adverse events. ConclusionPER and OXC monotherapy demonstrated similar efficacy and safety in the treatment of newly diagnosed adult focal epilepsy, and both drugs can be used as safe and effective treatment options.
Objective To review the examination techniques and the current research progress of the magnetic resonance diffusion weighted-imaging (DWI) used in liver. Methods The recent and relevant literatures about the principles and the current study situation of liver DWI were scrutinized and analyzed retrospectively. In addition, the existing problems of liver DWI were discussed. Results DWI could demonstrate the normal and abnormal structure and function through measuring the diffusion motions of water molecule in the liver. With the improving technology and better understanding of diffusion dynamics, DWI has been used for the diagnosis and differential diagnosis for hepatic diseases. Conclusion DWI as a non-invasive examine method, may provide valuable functional information for clinical diagnosis and treatment.
ObjectiveThrough neuropsychological assessment, explore the factors that may cause cognitive impairment in patients with focal epilepsy.MethodsCollected 53 epilepsy patients in outpatients and inpatients of Tianjin Medical University General Hospital from March 2016 to January 2020, including 25 males and 28 females, with an average age of (23.58±13.24) years old, and the course of disease (6.49±7.39), all met the 2017 ILEA diagnostic criteria for focal epilepsy, and there was no history of progressive brain disease or brain surgery. Carry out relevant cognitive assessments for the enrolled patients, use SPSS statistical software to conduct Spearman correlation analysis on the cognitive functions of the study subjects, and further analyze the related factors of cognition through Logistic regression analysis to clarify the factors related to cognition whether it may be a risk factor for cognitive impairment in patients with focal epilepsy.Results Spearman correlation analysis showed that the FIQ of patients with focal epilepsy was related to education level, age of onset, seizure pattern, total number of seizures, AEDs and EEG interval discharge side (P<0.05). Binary Logistic regression analysis shows that among all cognitive-related factors, only the number of AEDs (P=0.003) and EEG interval discharge (P=0.013) are the risk of cognitive impairment in patients with focal epilepsy factor.ConclusionIn the clinical treatment of epilepsy, seizures should be actively controlled, but the types of drugs should be minimized. When there are more than 3 kinds of drugs, surgical treatment or other non-surgical treatments can be considered. At the same time, the EEG should be reviewed regularly to understand the changes in epileptiform discharges between episodes.
ObjectiveTo explore the clinical features and sum up the laws of the hepatic focal nodular hyperplasia (FNH) in its diagnosis and treatment. MethodsFNH was an uncommon benign hepatic tumor that often posed diagnostic dilemmas. We analyzed retrospectively the clinical, imaging of ultrasound, imaging of computed tomography (CT) and magnetic resonance images (MRI), and pathological materials of 21 patients with FNH proven by the pathological diagnosis during 5 years from April 1996 through April 2001 in two hospitals. ResultsThe diagnosis of FNH remained a challenge for clinicians and surgeons. Rate of correct diagnosis of FNH was low preoperatively (19.0%). The lesions of FNH were seen in males and females (m/f: 14/7). Only three female patients (3/7) had the history of taking oral contraceptive. Patients with FNH were largely young and middle age persons (81.0% under 50 years), discovered by accident (57.1%), without infection of the hepatitis B virus (95.2%) and with normal liver functions (100%) and serum AFP levels (100%). Color Doppler ultrasound showed blood vessels passing through the lesion (80.0%) and there was abundant in blood (66.7%). CT scan showed that the lesion had transient immediate enhancement in 60.0% of patients and had homogeneous signal in 60.0% after bolus injection. MR imaging demonstrated early vigorous enhancement (64.3%), homogenous signal (57.1%) and having central scar (35.7%) in the lesion. The demonstration of a central scar in the lesion was very helpful for the diagnosis of FNH. MRI was more helpful for the diagnosis of FNH using liver specific contrast agents: superparamagnetic iron oxide（SPIO）. All patients underwent focus resection (18 cases) or segmentectomy (2 cases), except one having no treatment. ConclusionFNH shows some typical clinical and imaging features. We could increase the rate of correct diagnosis by comprehensively analyzing the clinical and imaging materials. It is very important and necessary to determine a definite diagnosis of FNH, hepatic adenoma (HA) and primary liver cancer (PLC) preoperatively, because the HA and PLC must be surgically resected, FNH can only be followed up.
Objective To evaluate the sensitivity and accuracy of SPIO-enhanced MR Imaging in the detection of focal hepatic lesions. Methods We searched MEDLINE (1966 to 2004), EMBSAE (1984 to 2004), The Cochrane Library (Issue 1, 2004), CBMdisc (Jan.1978 to Jul. 2004), CMCC (1994 to 2004), “Radiology”, “AJR” and “European Radiology” database. Data from pharmaceutical companies and our research were also added. Related journals published from 1985 to 2003 were handsearched. Participants were clinically suspected of focal hepatic lesions. The quality of studies was assessed, and descriptive systematic review was applied to evaluate the detection sensitivity and accuracy of the imaging modality. Results Ten studies (418 patients with 1 037 focal hepatic lesions) were included. Because the data of sensitivity and specificity could not be extracted from any of the 10 included studies, it was impossible to do the meta-analysis using SROC curve. The sensitivity of SPIO-enhanced MRI ranged from 66% to 100%; accuracy ranged from 76% to 97%. Conclusions At present, there is no evidence to ascertain that SPIO-enhanced MRI has a considerably high accuracy in the detection of focal hepatic lesions. More studies with good methodology are needed.
Objective To analyze the relationship between the epidermal growth factor receptor(EGFR) gene mutation and malignant pulmonary focal ground-glass lesion (fGGL). Methods We retrospectively collected the clinical data of 86 patients with surgical treatment in the department of cardiothoracic surgery of Changzheng Hospital from August 2012 to February 2015. There were 26 males and 60 females with a mean age of 56.14±10.55 years. We analyzed the relationship between the EGFR gene mutation and the related clinical data. Results Postoperative pathology showed atypical adenomatous hyperplasia (AAH) combined with focal adenocarcinoma in situ (AIS) or AIS in 10 patients, minimally invasive adenocarcinoma (MIA) in 15, and lepidic predominant adenocarcinoma (LPA) in 61. The EGFR gene mutation reports showed the exon 19 19-del mutation in 14 patients, exon 21 L858R mutation in 27, and exon 21 L861Q mutation in 2. There was no difference between the mutation of EGFR gene and clinical factors except age and smoking (P>0.05). Till June 30, 2015, all patients were alive and follow-up was 440.48±186.61 days. Conclusion The EGFR gene in patients with malignant pulmonary fGGL shows a higher mutation rate, which provides important clinical reference data for the basic research and the clinical treatment.
ObjectiveTo summarize the treatment of a patient with congenital portosystemic shunt (CPS) complicated with hepatic focal nodular hyperplasia (FNH), and to explore the feasibility and safety of combined laparoscopy and interventional radiology therapy at the same time.MethodsThe clinicopathological data of a patient with CPS complicated with hepatic FNH who admitted to West China Hospital of Sichuan University in March 2019 was retrospectively analyzed.ResultsThe patient underwent laparoscopic liver nodule resection and digital subtraction angiography (DSA) guided jugular portal portosystemic shunt fistula embolization. The laparoscopic surgery operation time was 180 min and the intraoperative blood loss was 50 mL, and for interventional procedure was 230 min and 10 mL respectively. There were no complications after operation and the patient was successfully discharged on the 8th day after surgery. The patient was followed up for six months and in good condition.ConclusionsCPS patient should develop individualized treatment under the discussion of multidisciplinary cooperation group. The combination of laparoscopy and interventional technique can be minimally invasive and efficient to solve portal vein-avitary shunt fistula and benign hepatic nodules at the same time.
