Comparison of self versus expert-assisted feedback for cricothyroidotomy training: a randomized trial.

BACKGROUND: The self-video feedback method may have the potential to provide a low-cost alternative to physician-driven simulation-based training. This study aimed to assess the utility of two video feedback methods by comparing the improvement in performing cricothyroidotomy procedure following self video feedback (trainees review their performance by themselves) and expert-assisted video feedback (trainees review their performance while an emergency physician provides additional feedback). METHODS: This study was pretest-posttest and two-group designed research performed at a university simulation center with 89 final-year medical students and used a cricothyroidotomy simulation model. After seeing an educational presentation and a best practice video, trainees were randomized into two groups; self video feedback group (SVFG) and expert-assisted video feedback group (EVFG). They performed the cricothyroidotomy before and after the feedback. The procedures were also recorded and scored by two emergency physicians. RESULTS: There was a statistically significant improvement between pre-feedback and post-feedback assessments in terms of scores received and time needed for the procedures in both SVFG and EVFG groups (p < 0.05). Additionally, the post-feedback assessment scores were higher and time needed for the procedure was lower in the EVFG when compared with SVFG (p < 0.05 for both). CONCLUSIONS: Results demonstrated significant improvement in cricothyroidotomy performance with both types of video feedback method. Even though the improvement was better in the EVFG compared to the SVFG, the self video feedback may have value especially in situations where expert-assisted feedback is not possible.

The state of ethics education at medical schools in Turkey: taking stock and looking forward.

BACKGROUND: Ethics teaching is globally considered an essential part of medical education fostering professionalism. It does not only provide knowledge for good clinical conduct, but also trains medical students as virtuous practitioners. Although Turkey has had a considerable experience in ethics education of healthcare professionals, the general state of ethics curricula at medical schools in Turkey is unknown. METHODS: The purpose of this study was to collect comprehensive data about the ethics education programs at medical schools in Turkey. To this aim, we designed a cross-sectional descriptive questionnaire survey which focuses on the content, teaching years, teaching, assessment and evaluation methodologies, workforce and infrastructure. We delivered the questionnaire to all medical schools in Turkey. Seventy-nine medical schools participated in this study (response rate: 78%). RESULTS: Although most institutions had an undergraduate ethics curriculum (91.1%), the findings suggest deficiency of teaching personnel (34.2% had no instructors). Furthermore, the distribution and composition of the workforce was imbalanced. The content varies largely among institutions. Medical schools with an ethics department were more likely to diversify teaching topics. However, ethics education was largely based on the four-principle approach. The content was usually conveyed to students theoretically. Around 90% of schools had classroom lectures. It is the only method used at one-third of them. Clinical ethics education was mostly lacking. Multiple-choice tests were widely used to assess and evaluate student attainments (86.1%). CONCLUSIONS: Staff qualified to teach ethics and ethics education integrated into the six-year medical curriculum given by a multidisciplinary team are urgent necessities. Considering teaching, assessment and evaluation methodologies used, most medical schools seem to fall short of fostering students to develop ethical attitudes. Endeavors aiming for modern topics should be encouraged. As the organization ethics education change continuously, we think that a platform for monitoring ethics education at medical schools in Turkey should be established. Such a body would help ethics instructors to network and find solutions to current problems and build shared wisdom.

Pharmacologically induced absence seizures versus kindling in Wistar rats.

OBJECTIVE: This study aimed to investigate the effects of γ-butyrolactone (GBL), a prodrug of gamma-Hydroxybutyric acid -induced absence seizures on the development of kindling in Wistar rats. METHODS: Three groups of adult male Wistar rats under anesthesia were implanted with bilateral cortical recording electrodes for the GBL group (GBL) and/or bipolar stimulation electrodes into the right basolateral amygdala for the Kindling group (KI) alone and Kindling plus GBL group (GBL+KI). Rats in the KI and GBL+KI groups were stimulated twice daily at the afterdischarge threshold until they reached Racine's stage 5 seizure state. The animals in the GBL + group had an i.p injection of GBL 20 minutes before each electrical stimulation, and the effects of GBL-induced seizures on the development of kindling were investigated. The animals in the GBL group were injected GBL twice daily i.p. for 15 days without receiving any electrical stimulation. RESULTS: The KI animals reached stage 5 seizure stage at 12th stimulations, whereas the GBL+KI rats reached at 27th stimulations. The mean numbers of stimulations needed for the development of the first stage 3, 4, or 5 generalized seizures were significantly higher in the GBL+KI group than the KI group. CONCLUSION: The resistance to amygdala kindling in the GBL model can be modulated by the absence seizure mechanism alone, without the intervention of an abnormal genetic background.

Child health, parasites and lower socioeconomic status: Outcomes of a long-term screening, intervention and training study by health volunteers in rural Nepal.

BACKGROUND: Nepal is a developing country with limited resources for health provision due to its geographic difficulties and frequent natural disasters, such as floods and earthquakes. Children are at risk of growth retardation due to inadequate food intake and unhealthy environment. Lower back pain is common among the adults and causes limitations in daily activities. MATERIAL/METHODS: A group of voluntary Turkish medical students, doctors and civil members conducted a field study, together with Nepalese doctors (MDs) and local volunteers, concerned with health-screening, intervention practices and on-site training in rural Nepal between 2013 and 2015. Physical examination of participants, together with stool examinations for parasites were done and those for whom treatment was indicated were referred to MDs who also ran a field pharmacy containing donated medications. RESULTS: Totally, 1148 individuals-725 children and 423 adults-were screened between 2013 and 2015. Musculoskeletal problems and upper respiratory tract infections were primary complaints among adults and sick children, respectively. Three-quarters of 203 collected stools had ≥ 1 parasite(s). CONCLUSIONS: Growth retardation in children observed during the study, the burden of intestinal parasites on Nepalese children and unavailability of effective health services for citizens in rural areas should direct local authorities to allocate greater resources for country's health infrastructure improvement and to provide a higher standard of childhood nutrition.

Orexins increase penicillin-induced epileptic activity.

Orexins have been implicated with physiological function including sleep-wake cycle, energy homeostasis, drinking behavior, analgesia, attention, learning and memory but their effects on excitability are controversial. We investigated the effects of intracortical injections of orexin A (100 pmol) and B (100 pmol) on the electrophysiological manifestation of epileptic seizures induced by cortical penicillin application in adult male rats. In comparison to saline, orexin A and B enhanced significantly the spike number, spike amplitude and spectral power values induced by cortical penicillin. Our findings indicates that orexins enhances the hyperexcitable and hypersyncronic cortical epileptic activity induced by focal application of penicillin-G.

Orexins cause epileptic activity.

Orexins have been implicated in the regulation of sleep-wake cycle, energy homeostasis, drinking behavior, analgesia, attention, learning and memory but their effects on epileptic activity are controversial. We investigated whether intracortical injections of orexin A (100 pmol) and B (100 pmol) cause epileptic activity in rats. We observed epileptic seizure findings on these two groups rats. Orexin A and B also significantly increased total EEG power spectrum. Our findings indicate that orexins cause epileptic activity.

Penicillin-induced epilepsy model in rats: dose-dependant effect on hippocampal volume and neuron number.

This study was designed to evaluate the penicillin-induced epilepsy model in terms of dose-response relationship of penicillin used to induce epilepsy seizure on hippocampal neuron number and hippocampal volume in Sprague-Dawley rats. Seizures were induced with 300, 500, 1500 and 2000IU of penicillin-G injected intracortically in rats divided in four experimental groups, respectively. Control group was injected intracortically with saline. Animals were decapitated on day 7 of treatment and brains were removed. The total neuron number of pyramidal cell layer from rat hippocampus was estimated using the optical fractionator method. The volume of same hippocampal areas was estimated using the Cavalieri method. Dose-dependent decrease in hippocampal neuron number was observed in three experimental groups (300, 500 and 1500IU of penicillin-G), and the effects were statistically significant when compared to the control group (P<0.009). Dose-dependent decrease in hippocampal volume, on the other hand, was observed in all three of these groups; however, the difference compared to the control group was only statistically significant in 1500IU of penicillin-G injected group (P<0.009). At the dose of 2000IU penicillin-G, all animals died due to status seizures. These results suggest that the appropriate dose of penicillin has to be selected for a given experimental epilepsy study in order to demonstrate the relevant epileptic seizure and its effects. Intracortical 1500IU penicillin-induced epilepsy model may be a good choice to practice studies that investigate neuroprotective mechanisms of the anti-epileptic drugs.

The role of bcl-2 family of genes during kindling.

PURPOSE: Several experimental models of human temporal lobe epilepsy have shown that apoptotic death of neurons is an important part of this degenerative disease. However, the role of apoptotic regulators is not clear during the epileptogenesis. Therefore we investigated the expression pattern of bcl-2 family of genes during the formation of kindling model of epilepsy in rats. METHODS: We examined the expression pattern of bax, bcl-2, bcl-xL, mtd, and bcl-w both at messenger RNA (mRNA) and protein level in the brain tissues during the formation of epilepsy with kindling model in adult rats, which has been the most acceptable form of experimental model of human epilepsy. We also assessed the onset of DNA fragmentation by using the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay. RESULTS: Animals have started to have epileptic discharges after day 10 of kindling model. Recurrent subthreshold electrical stimuli induced not only epileptic foci but also the expression of bax, an inducer of apoptosis, in this time period. Conversely, bcl-xL, which is an inhibitor of apoptosis, had an opposite pattern of expression both at mRNA and protein level during the formation of epilepsy. We did not observe DNA fragmentation by TUNEL staining. CONCLUSIONS: Our study shows differential expression of Bax and Bcl-xL at the CA1 region during the formation of hippocampal kindling model. The absence of DNA fragmentation during this period suggests that epileptic changes in neurons have the potential to induce DNA fragmentation by altering the expression levels of Bax and Bcl-xL.
