Wolff-Parkinson-White syndrome is the most common preexcitation syndrome.\u0000\u0000\u0000AIM OF THE STUDY\u0000The aim of the study was to evaluate the clinical course of the disease, as well as the treatment of children and adolescents hospitalized in the Department of Pediatric Cardiology in the years 2008-2015.\u0000\u0000\u0000MATERIALS AND METHODS\u0000The study was carried out in 45 children (62 % male, 38% female; the mean age 11 years). During the study we analyzed 12-lead ECG, 24-hour Holter ECG, echocardiography and the cycloergometric exercise test. The results of treatment were also discussed.\u0000\u0000\u0000RESULTS\u0000Apart from the typical features of preexcitation, the most prevalent abnormality found in ECG was atrioventricular reentrant tachycardia. In 24-hour Holter ECG the most frequently detected disorders were premature ventricular beats and premature atrial contractions. Structural heart defects were detected in 8.9% of the children. The cycloergometric exercise test was positive in 8.9% of patients. The mean duration of symptoms before the diagnosis was 2.5 years. 25% of the patients were asymptomatic. 42.2% of the children needed antiarrhythmic therapy, while 44.4% had accessory pathways ablated.\u0000\u0000\u0000CONCLUSIONS\u0000The most common symptom of preexcitation in the study group were heart palpitations. The most frequent type of arrhythmia in children with preexcitation syndrome was orthodromic atrioventricular reentrant tachycardia. For the majority of older children ablation of the accessory pathway was a recommended form of treatment. In younger children the standard preventive pharmacological treatment was applied for 6 to 12 months.Charakterystyczną cechą zespołów preekscytacji jest obecność dodatkowej, nieprawidłowej drogi przewodzenia w sercu.

A variety of disorders can cause epileptic spasms, with the etiology driving management, prognosis, and overall outcome. Preexisting brain damage has been demonstrated in 60% to 90% of the cases reflecting pre-, peri-, or postnatal brain injury that may usually be determined by history and clinical neurologie examination. Cerebra/ malformations may account for up to 30% of the cases [2]. Prenatal a/coho/ exposure can permanently damage the brain, affecting important structures, such as the cerebellum, corpus callosum as we/I as specific cell populations in many other regions of the brain. No one knows what a \"safe\" amount of a/coho/ consumption du ring pregnancy may be [3].\u0000\u0000\u0000OBJECTIVE\u0000The aim of this article is to present a clinical case of a large brain tempora/ lobe malformation which was recognized after a very early onset of spasms registered on video EEG-monitoring followed by MRI findings and to put forward the assumption that regular consumption of light alcoholic drinks even in low doses could con tribute to irreversible brain damage in the fetus.\u0000\u0000\u0000MATERIAL AND METHODS\u0000All patient data were collected from the N/CU and Newborn Patho/ogy Department of Lviv City Children's Clinical Hospital Health Record Department, and included the hospital and clinic records by the staff neurologist, neurophysiologist, and pediatrician, as we/I as EEG records in the postneonatal period. The mother was interviewed to clarify the pregnancy course data. The mother's consent was obtained for publication.\u0000\u0000\u0000RESULTS\u0000Asymmetric spasms, which were recognized as seizures on the 4th day of the child's life white recording video EEG, urged the physicians towards further diagnostic investigations. Primarily the child was diagnosed with neonatal abstinence syndrome on the 2nd day of life based on clinical and patient history data, but on the following day episodes of myoclonic jerks and jitteriness were noticed and video EEG monitoring started. Upon analysis of video- EEG, myoclonic seizures and spasms were reported showing asymmetry in the amplitude of ictal EEG. MRI was recommended and performed to explain focal EEG findings, and a large brain left temporal lobe malformation was seen.\u0000\u0000\u0000CONCLUSIONS\u0000Spasms in the form of seizures are rarely reported in the neonatal period. Their recognition has to lead to urgent brain imaging study to look for the underlying cause and to implement timely, appropriate corrections in the treatment strategy. Although brain malformations can have many causes, taking careful antenata/, perinatal and family history has ruled out many usual etiologies. Materna/ alcohol consumption during pregnancy may potentially have contributed to the condition.","PeriodicalId":35058,"journal":{"name":"Medycyna wieku rozwojowego","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69886725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patients were divided into 2 groups according to the presence of fetal/neonatal complications: the first group (n=14) - with complications (defined as one or more of the following: stillbirth, neonatal death, respiratory distress syndrome (RDS), intraventricular haemorrhage (IVH) Grade III or IV , necrotic enterocolitis (NEC), proven neonatal sepsis or bronchopulmonary dysplasia (BPD)) and the second one (n=39) - without severe complications.\u0000\u0000\u0000RESULTS\u0000Gestational age at diagnosis and at delivery was lower in the first group (28.5 weeks vs. 32.15 weeks, p=0.003 and 29.2 weeks vs. 32.8 weeks, p=0.0004).

An understanding of the role that nitric oxide plays in the management of threatened preterm labor may lead to more effective treatment and prevention. This is why the aim of our study was to examine the involvement of exogenous nitric oxide release in regulating responses of the human pregnant myometrium to oxytocin. Biopsies of human myometrial tissue during pregnancy were obtained from 8 pregnant women, aged 21-35 years. The responses of the specimens to oxytocin in the absence and presence of a DETA/NO were recorded under isometric conditions. Preincubation with exogenous nitric oxide significantly (p<0.001) attenuated the contractile response of the uterine strips to oxytocin in concentrations higher than 10 -8 mol/L. The inhibition of nitric oxide synthesis alone or in combination with DETA/NO incubation did not significantly change the oxytocin contractile effect in the concentration-response curve. Moreover, there was no significant variation in the mean value for log EC 50 for oxytocin between the group with oxytocin alone and other groups. We present evidence in support of the hypothesis that continuous nitric oxide supply to the human pregnant myometrium environment attenuates its response to oxytocin but only when endogenous production of nitric oxide is not impaired.","PeriodicalId":35058,"journal":{"name":"Medycyna wieku rozwojowego","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69886594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
