Effects of the Calcium Channel Blocker Otilonium Bromide on Seizure Activity in Rats With Pentylenetetrazole-Induced Convulsions
No full textPubMed: 33811624WOS:000636413000001Millions of people suffer from drug-resistant epilepsy. New therapeutic approaches for removing this life-affecting disease are required. The activation of T-type calcium channels (TTCC) is one of the epileptogenesis mechanisms that cause epilepsy. So, we researched the effects of Otilonium bromide (OB), an antisposmolytic drug that inhibits TTCC, on seizure activity in rats with pentylenetetrazol (PTZ) induced convulsion. Randomly, 48 rats were divided into two groups; for electroencephalography (EEG) recordings and for behavioral assesment. Rats were treated with either intraperitoneal (IP) OB at two separate doses (25 mg/kg and 50 mg/kg) or placebo, and then pentylenetetrazole (IP), a potent seizure-inducing chemical administered to them. In our model we have measured rat seizure activity with EEG, the convulsion scala of Racine (RCS), the time of first myoclonic jerk (FMJ) and MDA levels to assess if OB has antiepileptic properties. The mean EEG spike wave percentage score reduced from 79.5% (placebo) to 59.2% (lower-dose) and 35.2% (higher-dose). FMJ had increased from a mean of 67.2 s (placebo), to 105.2 (lower-dose), 150.6 (higher-dose). RCS reduced from a mean of 5.12 (placebo) to 4.4 (lower-dose), 3.8 (higher-dose). MDA leves reduced from 84.5 nmol/gr to 51.09 nmol/gr (lower-dose), 33.2 nmol/gr (higher-dose). Compared to placebo, OB reduced significantly seizure activity at both doses, probably through blocking T-type calcium channels. All these results were statistically significant with < 0.0001 p-values. Otilonium bromide reduced seizure activity in rats with PTZ-induced convulsion. Therefore, the clinical role of OB and other TTCC inhibitors as potential anti-seizure drugs should be further investigated
Neuroprotective effects of dexpanthenol on streptozotocin-induced neuronal damage in rats
No full textErdogan, Mumin/0000-0003-0048-444XPubMed: 33874839WOS:000641505500001Aim Although the most common age-related neurodegenerative disease defined by memory loss is Alzheimer's disease (AD), only symptomatic therapies are present. A complex pathway for the AD pathogenesis that includes an increase in inflammation has recently been suggested. Since in previous animal experiments dexpanthenol has anti-inflammatory and neuroprotective activities, effects and role of dexpanthenol in an intracerebroventricular (ICV)-streptozotocin (STZ) induced sporadic-AD(memory impairment) animal model have been examined. Design and methods In total, 18 adult sprague-dawley rats were classified into 3 groups; control (n = 6), STZ + Saline (n = 6) and STZ + Dexpanthenol (n = 6). Twelve AD-induced rats through STZ-injection (3 mg/kg) into both lateral ventricles via stereotaxy were separated into two groups five days after STZ administration: one of these groups was treated with dexpanthenol (1000 mg/kg/day, i.p.) for 3 weeks and the other with saline. A passive avoidance learning (PAL) test was used after treatment, followed by brain tissue extraction in all subjects. Brain levels of tumor necrosis factor-alpha (TNF-alpha) and choline acetyl transferase (ChAT) were measured and Cresyl violet staining was used to count neurons in cornu ammonis-1 (CA1) and cornu ammonis-3 (CA3). Results It was observed that ICV-STZ significantly shortened PAL latency, increased levels of TNF-alpha in brain, decreased activity of ChAT in brain, and number of hippocampal neurons. However, dexpanthenol significantly reduced all of those STZ-induced harmful effects. Conclusion Dexpanthenol significantly prevented the memory deficit induced by ICV-STZ through mitigating neuronal loss in hippocampus, cholinergic deficiency and neuroinflammation in rats. These findings suggest that dexpanthenol may be beneficial for treating memory impairment
Febrile Seizures in Idiopathic/Genetic Generalized and Self-Limited Focal Epilepsies
No full textWOS:000652737400007Objectives: Febrile seizure (FS) is the most common form of childhood seizures. Furthermore, idiopathic/generalized and focal/self-limited epilepsies present at the similar age-range. They usually have a favorable outcome. This study was conducted to investigate the prevalence and demographic profile of FS in patients with idiopathic/generalized and focal/self-limited epilepsies. Methods: This retrospective study included all of the patients with normal developmental assessments who were admitted to our outpatient clinic with idiopathic/generalized and focal/self-limited epilepsy. The data were collected from their medical and electroencephalogram records. The patients were subgrouped according to their syndromes and the presence of FS. Comparisons were made for the characteristics of FS. Results: Among 320 patients with the diagnosis of focal or generalized epilepsy with presumed genetic cause, FSs were present in 14.7% (n=47) of them without gender preponderance. Self-limited focal epilepsy was present in 232 children (72.5%). The mean age of epilepsy onset was 7.97 +/- 3.38 years (range: 1-18 years). Although the distribution of FSs in focal or generalized epilepsy groups (p=0.552) and subtypes of these groups (p=0.701) did not indicate any statistical significance, highest ratios of FS occurrence were found in juvenile myoclonic epilepsy and idiopathic photosensitive occipital lobe epilepsy groups. Conclusion: Gender, family history of epilepsy and FS, onset age of epilepsy, type of epilepsy did not seem as a predictor factor for subsequent epilepsy in the patients with FS otherwise normal children
The role of interventional pulmonology for the postoperative bronchopleural fistula
No full textPubMed: 340189702-s2.0-85107081608Background: : Postoperative bronchopleural fistula (BPF) remains a serious complication due to its high morbidity and mortality. Although various endoscopic techniques have been defined for the closure of BPF previously, no standard algorithm yet exists. Aims: To study the effectiveness and safety of various endoscopic procedures in an interventional pulmonology unit. Materials and Methods: The medical data of 15 postoperative BPF patients, who were undergone endoscopic intervention were retrospectively investigated. Results: The mean size of the fistulas determined by bronchoscopic evaluation was 7.93 ± 3.26 mm (range 3-15 mm). Applied procedures were as follows: stent implantation (n: 8, 53.3%), stent implantation and polidocanol application (n: 4, 26.7%), only Argon Plasma Coagulation (APC) application (n: 2,13.3%), polidocanol application (n: 1,6.7%). Complete fistula closure was achieved in three of the 15 patients (20%). The procedures were partly successful in five (33.3%) patients and failed to be successful in seven (46.6%) patients. Survival rates in regard to procedural success were determined and a statistically significant difference was found in five-year survival rates (P = 0.027, P < 0.05). Conclusion: Our results demonstrated that bronchoscopic procedures can be safely and effectively performed in patients who were not eligible for surgery for various reasons

Neuroimaging in Developmental Coordination Disorder
No full textWOS:000635642700002Developmental coordination disorder (DCD) is a neuromotor disorder of unknown etiology characterized by motor skill disorder, which significantly inhibits the child's ability to perform daily living activities and affects psychosocial well-being. DCD is one of the least understood and studied neuromotor disorders, and little is known about the neural mechanisms underlying motor impairment. This makes it difficult to understand why children with DCD have difficulty in learning motor skills and what is the best intervention to optimize motor functions. With the further development of neuroimaging techniques, the number of neuroimaging studies to understand the underlying mechanisms in children with DCD has increased in recent years. Results from these studies suggest that children with DCD activate different regions of the brain during functional tasks and show differences in white matter microstructure, cerebellum, basal ganglia, parietal lobe, and parts of the frontal lobe (medial orbitofrontal cortex and dorsolateral prefrontal cortex) compared with typically developing children. We believe that these neuroimaging data obtained from numerous studies will contribute to the explanation of neural mechanisms related to impaired motor function in children with DCD
Case stories and Post-violence behavior of women seeking medical attention at the emergency department due to physical violence
No full textPubMed: 339327412-s2.0-85105268510Subject: The objective of this study is to determine the violence experienced by women who presented to the Emergency Department (ED) due to Intimate Partner Violence (IPV) and their previous experiences of violence. Method: The descriptive study was conducted with 96 women. The data was analyzed in SPSS 17.0 statistics package program. Findings: The average age of the women is X = 35.33 ± 11.72, 35.4% of them are in the 31–40 age group, 69.6% are married, 44.8% are high school graduates, 60.4% are unemployed. It was determined that women who were IPV victims were exposed to violence by being beaten (punching, kicking etc.) at the highest rate (82.3%), and nearly half of them (47.9%) were injured in the head and neck regions. The vast majority of women (86.5%) have been subjected to violence before, only %13.5 of them stated that they experienced violence for the first time. It was found that the majority of women (69.8%) continued to live with the perpetrator after violence. Only three of the women (3.4%) attempted to initiate legal action, and the majority (76.5%) did not intend to take legal action. Conclusions: Healthcare professionals should be aware that most woman presenting to the ED with IPV has a history of violence before it, and that this will probably not be the last. Healthcare professionals should also consider the fact that the victims may be exposed to different types of violence at the same time. It is also recommended that healthcare professionals be trained on policies regarding IPV management and equipped to provide women with the right way out. © 202
Real life data of treat and extend intravitreal ranibizumab and aflibercept therapy in wet age-related macular degeneration patients: 3-year results
No full textPurpose: To compare functional and anatomic outcome of intravitreal ranibizumab (IVR) and intravitreal aflibercept (IVA) treatments in neovascular age-related macular degeneration by using the treat and extend (TE) protocol. Methods: In this retrospective chart study, treatment naïve 74 eyes of 74 age-related macular degeneration patients treated with IVR and IVA (38 eyes in IVR and 36 eyes in IVA group) with TE protocol were included. Following three consecutive monthly intravitreal injections, TE protocol was applied to each group. Patients were followed up for at least 36 months. Mean change in best-corrected visual acuity (BCVA), central macula thickness (CMT) and injection numbers over 3 years were compared. Results: Among 36 months period, the mean number of injections was 17 ± 4 for both groups (p > 0.05). In terms of CMT, there was no statistically significant difference between groups at 36 months compared to baseline. A decrease of 72.55 ± 39.37 ?m in CMT was detected in IVR group, whereas the decrease was 70.58 ± 33.96 ?m in IVA group (p > 0.05). There was a significant increase in BCVA at 36 months of measurements. In addition, BCVA demonstrated an increase of 4.1 ± 0.44 letters in IVR group and 4.36 ± 0.67 letters in IVA group after 36 months compared to the baseline (p > 0.05). Conclusions: Both IVR and IVA injections provided significant improvements and stability in BCVA and CMT, however there was no significant difference between IVR and IVA injections with TE protocol of 36 months. © Korean Journal of Ophthalmology 2021
NON-INTRINSIC CANCER RISK FACTORS
No full textOur knowledge about the etiology of cancer is increasing. Many studies show that non-intrinsic factors such as environment or lifestyle are the main risk factors for the occurrence of cancer. On the other hand, there are studies showing that the main risk factors in the occurrence of cancer are caused by DNA replication errors (known as the intrinsic factors). This view limits highly the possibility of protection from cancer. However, the findings obtained from the literature show that non-intrinsic factors contribute substantially to cancer risk and that cancer should be considered as a preventable disease. This review is aimed to examine the factors known as non-intrinsic cancer risk factors in the light of recent research. Copyright © Experimental Oncology, 202
