S100B proteins in febrile seizures

AbstractS100B protein concentrations correlate with the severity and outcome of brain damage after brain injuries, and have been shown to be markers of blood–brain barrier damage. In children elevated S100B values are seen as a marker of damage to astrocytes even after mild head injuries. S100B proteins may also give an indication of an ongoing pathological process in the brain with respect to febrile seizures (FS) and the likelihood of their recurrence. To evaluate this, we measured S100B protein concentrations in serum and cerebrospinal fluid from 103 children after their first FS. 33 children with acute infection without FS served as controls for the serum concentrations. In the FS patients the mean S100B concentration in the cerebrospinal fluid samples was 0.21μg/L and that in the serum samples 0.12μg/L. The mean serum concentration in the controls was 0.11μg/L (difference 0.01μg/L, 95% confidence interval −0.02 to 0.04μg/L, P=0.46). There was a correlation between age and serum S100B concentration (r=−0.28, P=0.008) in children under four years, but S100B concentrations did not predict the clinical severity of the FS nor their recurrence. There was no correlation between time of arrival at the hospital after FS and S100B concentration in serum (r=−0.130, P=0.28) or in cerebrospinal fluid samples (r=−0.091, P=0.52). Our findings indicate that FS does not cause significant blood–brain barrier openings, and increase the evidence that these seizures are relatively harmless for the developing brain

Xylitol-supplemented nutrition enhances bacterial killing and prolongs survival of rats in experimental pneumococcal sepsis

<p>Abstract</p> <p>Background</p> <p>Xylitol has antiadhesive effects on <it>Streptococcus pneumoniae </it>and inhibits its growth, and has also been found to be effective in preventing acute otitis media and has been used in intensive care as a valuable source of energy.</p> <p>Results</p> <p>We evaluated the oxidative burst of neutrophils in rats fed with and without xylitol. The mean increase in the percentage of activated neutrophils from the baseline was higher in the xylitol-exposed group than in the control group (58.1% vs 51.4%, P = 0.03 for the difference) and the mean induced increase in the median strength of the burst per neutrophil was similarly higher in the xylitol group (159.6 vs 140.3, P = 0.04). In two pneumococcal sepsis experiments rats were fed either a basal powder diet (control group) or the same diet supplemented with 10% or 20% xylitol and infected with an intraperitoneal inoculation of <it>S. pneumoniae </it>after two weeks. The mean survival time was 48 hours in the xylitol groups and 34 hours in the control groups (P < 0.001 in log rank test).</p> <p>Conclusion</p> <p>Xylitol has beneficial effects on both the oxidative killing of bacteria in neutrophilic leucocytes and on the survival of rats with experimental pneumococcal sepsis.</p

Efficacy of the implementation of the National Emergency X-Radiography Utilization Study II decision rule to clinical practice for paediatric head injury patients

Aim To investigate the usefulness of the National Emergency X-Radiography Utilization Study (NEXUS) II head trauma decision rule in clinical practice for paediatric patients in a tertiary university hospital serving as the only paediatric hospital in the area. Methods We compared how doctors evaluated and examined patients with head injury during two time periods, before and after the introduction of NEXUS II decision rule. Multiple implementation strategies were used as follows: education, tutoring and written instructions for the use of NEXUS II. Results Two hundred and forty-four head injury patients visited the hospital before and 385 after the introduction of the NEXUS II decision rule. The number of hospital admissions (56%) and the mean duration of hospitalisation (2.5 days) remained the same during the two periods. In the NEXUS II evaluated group, there was a decrease of 40% in the number of hospital admissions. NEXUS II was applied in only 62 (16%) cases. The number of head imaging procedures remained the same. No patients with a clinically significant head injury were missed with the NEXUS II evaluation. Conclusion NEXUS II was ineffective as our implementation failed. When used, NEXUS II reduced expenses in our study population by decreasing the number of hospital admissions.Peer reviewe

Experiences of using an interactive audience response system in lectures

BACKGROUND: Lectures are good for presenting information and providing explanations, but because they lack active participation they have been neglected. METHODS: Students' experiences were evaluated after exposing them to the use of voting during lectures in their paediatrics course. Questions were delivered to the students taking paediatrics course. Thirty-six students out of the total of 40 (90%) attended the opening lecture, at which the first survey concerning previous experiences of lectures was performed. Thirty-nine students (98%) answered the second series of questions at the end of the paediatrics course. RESULTS: Most of the students felt that voting improved their activity during lectures, enhanced their learning, and that it was easier to make questions during lectures than earlier. CONCLUSIONS: The students gained new, exciting insights much more often during the paediatrics course than before. We as teachers found that voting during lectures could easily overcome some of the obstacles of good lecturing

Increased risk of respiratory viral infections in elite athletes: A controlled study

BackgroundRespiratory symptoms are commonly recognised in elite athletes. The occurrence, etiology and clinical presentation of the illnesses in athletes is unclear.MethodsWe performed a prospective controlled study of respiratory viral infections in Team Finland during Nordic World Ski Championships 2019. There were 26 athletes and 36 staff members. Nasal swabs were taken at the onset of a symptom and on days 1, 7, and 13 during the follow-up of 14 days. Respiratory viruses were searched for by 3 different molecular multiplex tests. Fifty-two matched control subjects were studied in Finland during the same period.ResultsTen out of 26 (38%) athletes, 6 out of 36 (17%) staff, and 3 out of 52 (6%) control subjects experienced symptoms of respiratory infection (p = 0.0013). The relative risks for acquiring symptomatic infection were 6.7 (95% confidence interval [CI], 2.1–21.0) of athletes and 2.9 (95% CI, 0.84–10.0) of the staff as compared to the controls. Asymptomatic infections were identified in 8%, 22%, and 19%, respectively (p = 0.30). The etiology of respiratory infections was detected in 84% of the cases.ConclusionThe athletes had a 7-fold increase in the risk of illness compared to normally exercising control subjects.</div

Hospital bed occupancy for rotavirus and all cause acute gastroenteritis in two Finnish hospitals before and after the implementation of the national rotavirus vaccination program with RotaTeq®

Background Vaccination-impact studies of the live-attenuated pentavalent oral vaccine Rotateq® have demonstrated that the burden of rotavirus gastroenteritis has been reduced significantly after the introduction of RotaTeq® vaccination, but less is known about the benefit of this vaccination on hospital overcrowding. Methods As part of an observational surveillance conducted during the RV seasons 2000/2001 to 2011/2012, we analysed hospital discharge data collected retrospectively from two Finnish hospitals (Oulu and Tampere), concerning ICD 10 codes A00-09 (acute gastroenteritis, AGE) and A08.0 (rotaviral acute gastroenteritis RV AGE). We estimated the reduction in the number of beds occupied and analysed the bed occupancy rate, for RV AGE and all cause AGE, among 0–16 year-old children, before and after the implementation of the RV immunisation program. Results The rate of bed days occupied for RV AGE was reduced by 86% (95% CI 66%-94%) in Tampere and 79% (95% CI 47%-92%) in Oulu after RV vaccination implementation. For all cause AGE, reduction was 50% (95% CI 29% to 65%) in Tampere and 70% (95% CI 58% to 79%) in Oulu. Results were similar among 0–2 year-old children. This effect was also observed on overcrowding in both hospitals, with a bed occupancy rate for all cause AGE >25% in only 1% of the time in Tampere and 9% in Oulu after the implementation of the immunisation program, compared to 13% and 48% in the pre-vaccination period respectively. After extrapolation to the whole country, the annual number of prevented hospitalizations for all cause AGE in the post-vaccination period in Finland was estimated at 1,646 and 2,303 admissions for 0–2 and 0–16 year-old children respectively. Conclusions This study demonstrated that universal RV vaccination is associated with a clear decrease in the number of bed days and occupancy rates for RV AGE and all cause AGE. Positive consequences include increase in quality of care and a better healthcare management during winter epidemics.BioMed Central open acces

Mistreatment of university students most common during medical studies

BACKGROUND: This study concerns the occurrence of various forms of mistreatment by staff and fellow students experienced by students in the Faculty of Medicine and the other four faculties of the University of Oulu, Finland. METHODS: A questionnaire with 51 questions on various forms of physical and psychological mistreatment was distributed to 665 students (451 females) after lectures or examinations and filled in and returned. The results were analysed by gender and faculty. The differences between the males and females were assessed statistically using a test for the equality of two proportions. An exact two-sided P value was calculated using a mid-P approach to Fisher's exact test (the null hypothesis being that there is no difference between the two proportions). RESULTS: About half of the students answering the questionnaire had experienced some form of mistreatment by staff during their university studies, most commonly humiliation and contempt (40%), negative or disparaging remarks (34%), yelling and shouting (23%), sexual harassment and other forms of gender-based mistreatment (17%) and tasks assigned as punishment (13%). The students in the Faculty of Medicine reported every form of mistreatment more commonly than those in the Faculties of Humanities, Education, Science and Technology. Experiences of mistreatment varied, but clear messages regarding its patterns were to be found in each faculty. Female students reported more instances of mistreatment than males and were more disturbed by them. Professors, lecturers and other staff in particular mistreated female students more than they mistreated males. About half of the respondents reported some form of mistreatment by their fellow students. CONCLUSION: Students in the Faculty of Medicine reported the greatest amount of mistreatment. If a faculty mistreats its students, its success in the main tasks of universities, research, teaching and learning, will be threatened. The results challenge university teachers, especially in faculties of medicine, to evaluate their ability to create a safe environment conducive to learning
