Clinical and neurophysiological changes in patients with pineal region expansions [Kliničke i neurofiziološke značajke u bolesnika s ekspanzivnim tvorbama pinealne regije]

In the last 20 years neurological and neurosurgical follow up of our patients with pineal region expansions (118 patients) pointed to certain clinical and neurophysiological regularities. We performed retrospective study which included 84 patients with pineal region expansions in the period from 1992 to 2009. The study included 55 women and 29 men, mean age 30.08 +/- 13.93 years, with positive brain magnetic resonance imaging (MRI)--70 patients (83.4%) had simple pineal gland cysts, and 14 patients (16.67%) had expansive process in pineal region with compressive effect. All patients had headache, while 32 patients (38%) had epileptic phenomena--primary generalized seizures. Patients had common electroencephalography (EEG) pattern with paroxysmal discharges of 3Hz (or more than 3 Hz) spike-and-wave complexes. Operation with supracerebellar infratentorial approach was performed in 70 patients. In most of our patients indication for the operation was established based on the size of the cyst (15 mm or more), with the signs of compression on the quadrigeminal plate and compression of the surrounding veins, which could result in seizures and EEG changes verified in our group of patients. Pathohistological analysis revealed pineocytomas in 11 cases (15.71%), pinealoblastomas in 2 cases (2.86%), one case of teratoma (1.43%), while 56 patients had pineal gland cysts (80%). Following surgery clinical condition improved in all patients--patients became seizure-free and headaches significantly decreased. Other symptoms including diplopiae, nausea, vomiting, vertigo as well as blurred vision also disappeared. There were no complications after surgical procedures. This study points to often appearance of seizures that clinically and neurophysiologically present as primary generalized epilepsy in patients with pineal region expansions. Our hypotheses are that mass effect on the surrounding veins that affects normal perfusion, compressive effect on the quadrigeminal plate and the aqueduct of the midbrain, hemosiderin deposists, as well as secretion disturbances of anticonvulsive agent melatonin can be involved in the pathogenesis of seizures. We suggest to perform high resolution brain MRI with special demonstration of pineal region in all young patients that have seizures and specific EEG changes

PREDICTORS OF QUALITY OF LIFE IN PATIENTS WITH DRUG RESISTANT EPILEPSY AFTER NEUROSURGICAL TREATMENT: ONE-YEAR FOLLOW-UP

Background: Invasive neurosurgical treatment or minimally invasive neurosurgical treatment are methods of choice for the treatment of patients with drug resistant epilepsy. The aim of this study was to evaluate the impact of neurosurgical treatment and the quality of life of patients with drug resistant epilepsy and to determine what are the potential predictors of quality of life of patients with drug resistant epilepsy one year after neurosurgical treatment. Subjects and methods: The research was performed at the Referral Centre for Epilepsy, Department of Neurology, University Hospital Centre Zagreb from February 2015 to February 2020 with Ethics commitee approval. The study included 96 patients with drug resistant epilepsy who were examined for the quality of life before and one year after neurosurgical treatment using the form questionnaire "Quality of life in epilepsy" (QOILE-31) validated Croatian 1.0 version and the questionnaire to assess the degree of depression "Beck Depression Inventory I" (BDI-I) validated Croatian version. Results: Of 96 patients with drug resistant epilepsy one year after neurosurgical treatment 46 (47.9%) patients remained completely free from epileptis seizures. Wilcoxon equivalent pair test showed that the number of epileptic seizures one year after neurosurgical treatment was significantly lower (median before neurosurgical treatment is 10; and after neurosurgical treatment is 1, p<0.001). The most informative potential statistically significant predictor variables of quality of life based on the criterion variables QOLIE-31 and BDI-I are: total disease duration in years (p=0.034), patient age (p=0.042), number of antiepileptics one year after neurosurgical treatment (p=0.001), the number of epileptic seizures per month (p=0,016), and social welfare rights (p=0.045). Conclusion: Neurosurgical treatment of patients with drug resistant epilepsy significantly reduces the number of epileptic seizures which significantly improves their overall quality of life one year after neurosurgical treatment

SEXUAL DYSFUNCTION IN PATIENTS WITH EPILEPSY

Background: Patients with epilepsy commonly report sexual dysfunction (SD) and reproductive difficulties. This study aimed to evaluate the relationship between epilepsy, antiepileptic drugs (AEDs) and SD, and its association with the quality of life and depressive symptoms. Subjects and methods: This was a prospective study carried out in a tertiary healthcare centre. SD was evaluated using the internationally acclaimed questionnaire Arizona Sexual Experiences Scale (ASEX) that was successfully translated into Croatian and validated for this purpose. Depressive symptoms and quality of life were evaluated using the Hamilton Rating Scale for Depression (HAM-D17) and Quality of life in epilepsy-31 inventory (QOLIE-31). Results: Of 108 patients (68 (63 %) women, 40 (37 %) men, mean age 39.54±15.91 (range18-80) years) with epilepsy, 16 (14.8%) had focal, 38 (35.2%) generalized and 44 (40.7%) both types of epilepsy. Mean overall total score on the ASEX questionnaire was 11.94±5.61 (mean total score women 12.85±6.00, mean total score men 10.4±4.55), with 48 reporting that they had sexual activity in the past week. Nine (8.33%) patients (7 (6.48%) women, 2 (1.85%) men, mean age 47.66±19.33 (range 25-80) years) had a score 19 and above, 38 (35.18%) patients (27 (25%) women, 9 (8.33%) men, mean age 46.82±17.78 (range 19-80) years) individual score 5 and above on any one item, and 33 (30.55%) patients (26 (24.07%) women, 7 (6.48%) men, mean age 48.87±17.8 (range 19-80) years) had an individual score 4 and above on any three items. Significant correlations were found between SD and older age (p=0.001) and between more pronounced symptoms regarding SD on ASEX and female gender (p=0.000). There were no significant correlations between the type of epilepsy and SD, nor between the AEDs (old generation vs. modern) and SD. Significant correlations were found between the SD and more pronounced depressive symptoms (p=0.003) and between the SD and a lower quality of life (p=0.001). Conclusions: Results of our study suggest SD is experienced by around one-third of patients in our group, which is similar to the previous percentage of SD reported in the community sample. Women were found to experience more pronounced symptoms of SD on ASEX. Symptoms of SD were found to be significantly correlated with older age, female gender, lower quality of life and depressive symptoms, while no significant correlations were found with the type of epilepsy and the AEDs
