Aim Posture requires fine integrative elaboration, performed by the central nervous system, of neurosensory information originated from the visual, vestibular and spinal circuit. Many perturbing agents can influence this elaboration and then the postural stability. Several studies have evaluated only the effect of a single agent on the postural control. ⋯ The rubber cushion increased the oscillation area in all OE tests and with CE in alcohol and ice tests. Conclusion The different agents did not trigger postural control deficits in the same way. A cold environment with psychedelic lights and the use of alcoholic beverages altered significantly the postural stability by influencing simultaneously all perceptions (visual, vestibular and somatosensory feedback).

Randomized Controlled Trial
Correlation of signal to noise ratio (SNR) value on distortion product otoacoustic emission (DPOAE) and expression of nuclear factor erythroid 2-related factor 2 (NRF2) in cochlear organ of Corti in rat exposed to noise.
Aim To investigate the changes in the value of the signal to noise ratio (SNR) and to assess changes in the expression of nuclear factor erythroid 2-related factor 2 (NRF2) in the organ of Corti of rat exposed to noise. Methods This study used a randomized post test only control group laboratory experimental design with 27 male Wistar strain Rattus norvegicus. The study group was divided into 3 groups (n = 9): group I (control), group 2 (2 hours of 100 dB noise exposure) and group 3 (2 hours of 110 dB noise exposure). ⋯ There was a significant difference in the mean levels of NRF2 expression in the cochlear organ of Rattus norvegicus in all groups (p<0.05). There was no correlation between the SNR and the NRF2 expression in group 2 (p>0.05), but there was a correlation between the SNR and the NRF2 expression in the group 3 (p<0.05). Conclusion There was found a correlation between the SNR value on distortion product otoacoustic emission (DPOAE) examination and NRF2 expression in the cochlear organ of Corti of Rattus norvegicus exposed to 110 dB noise.

Aim To investigate the effects of surgical reduction of complex acetabular fractures on spine balance, postural stability and quality of life. Methods Twenty-six patients with acetabular fractures surgically treated by open reduction and internal fixation were divided into two groups according to the amount of reduction. Group A consisted of 18 patients with satisfactory reduction (≤2 mm), and group B of eight patients with incomplete reduction (>2 mm). ⋯ After two years, 16 (89%) patients in group A and four (50%) in group B had a balanced spine (SVA <50 mm). Gait analysis and baropodometry showed greater imbalance and overload for group B compared to group A. Conclusion In the long term, incomplete reduction of associated acetabular fractures may lead to poor outcome because of secondary spinopelvic imbalance, with posture and gait impairment.

Aim To determine the effect of the load on the meniscus in relation to a different angle, and to present the impact of force on eventual injury of menisci. Methods Research included 200 males with average height of 178.5 cm, mass 83.5 kg, and average age of 22 years. The simulation of treadmill that was used in the evaluation of ischemic heart disease was made. ⋯ Results With increasing ascent of treadmill the load on the meniscus also increased. Each increase in ascent after 22% (which corresponded to the angle of 12°40' and seventh degree of load according to the Bruce protocol) at given anthropological values was an etiological factor for meniscus injury. Conclusion The seventh degree of load according to the Bruce protocol can lead to the meniscus injury.

Aim Children with congenital heart diseases are at the greater risk of respiratory tract infection such as pneumonia. Recurrent pneumonia is one of the most major challenge for paediatric physicians. The aim of this study is to investigate risk factors of congenital heart diseases to recurrent pneumonia children. ⋯ Ventricular septal defect had a possibility for recurrent pneumonia by 1.551 times, and malnutrition 2.591 times. Conclusion Ventricular septal defect and malnutrition were identified as risk factors for recurrent pneumonia. Those patients require multidisciplinary approach to prevent respiratory complications.
