Evaluation of the descriptive values and occlusion effects of air and bone conducted cervical vestibular evoked myogenic potentials in normal individuals

Objective:This study was aimed to establish the descriptive statistical values of cVEMPs's responses which are evoked by air and bone conducted stimuli and to examine the effects of occlusion on bone conducted (BC) cVEMPs test. Methods:The study was carried out on 20 individuals (n = 40 ears), 11 women and 9 men, at the Medipol Mega University Hospital. cVEMPs tests were applied in five stages to the individuals who are volunteer to participate in this study. Firstly, the air conducted (AC) cVEMPs test was applied. Then, BC cVEMPs tests were applied in four different conditions with the aim of examining the occlusion effect. Results:Latency values of the AC cVEMPs response were 15.17 +/- 0.77 ms for P1 and 24.12 +/- 1.38 ms for N1 and 8.95 +/- 1.12 ms for interpeak latencies. P1N1 amplitude value was 149.73 +/- 75.00 mu V. VEMPs asymmetry ratio (VAR) was 0.16 +/- 0.16. Latency measurements of the BC cVEMPs response were 14.38 +/- 0.85 ms for P1 and 23.40 +/- 1.50 ms for N1 and 9.05 +/- 1.57 ms for interpeak latencies. P1N1 amplitude value was 107.58 +/- 54.08 mu V. VAR was 0.15 +/- 0.12. Both AC cVEMPs and BC cVEMPs parameters were demonstrated that there are not any significant differences between female-male and left ear-right ear. When AC and BC cVEMPs responses were compared, the mean P1 and N1 latencies of BC cVEMPs were significantly shorter than those of AC cVEMPs (p < 0.01). The mean amplitudes of AC cVEMPs were significantly larger than those of BC cVEMPs (p < 0.01). When the impact of the occlusion effect on cVEMPs parameters was examined, no statistical significance was found. Conclusion:As a result, it was thought that the BC cVEMPs, which is not widely used in clinics, might be used in the vestibular assessment of conductive hearing losses (CHL) in clinics, by obtaining descriptive values with this study. In addition, it was thought that it might be used as an auxiliary test to diagnose patients with hyperacusis who are disturbed by loud noises

Investigation of the effects of narrowband and wideband noise on central inhibition in pure tone audiometry in individuals with hearing loss

Amaç: Bu çalışmada dar bant ve geniş bant gürültü kullanımının işitme kayıplı bireylerde santral inhibisyon değerlerine olan etkilerinin karşılaştırılması amaçlanmıştır. Gereç ve Yöntemler: 37 kişiye öncelikli olarak otoskopik bakı, saf ses odyometrisi, konuşma odyometrisi ve timpanometrik değerlendirmeleri yapılarak işitme kaybının lokalizasyonu, tipi ve derecesi belirlenmiştir. Ardından katılımcıların saf ses işitme eşiklerindeki değişiklikler test edilmeyen kulağa sırasıyla gürültü verilmeden, dar bant ve geniş bant gürültü verilerek test edilmiştir. Bulgular: Sensörinöral işitme kayıplı olgularda 250, 500, 2000 ve 8000 Hz frekanslarında; iletim tipi işitme kayıplı olgularda ise 250,500 ve 1000 Hz frekanslarında geniş bant gürültü kullanımı, eşik kaymasını azaltarak eşiklerde istatistiksel olarak anlamlı değişikliğe neden olmuştur (p<0,05). Sonuç: Çalışmamızda iletim tipi ve sensörinöral tip işitme kayıplarında geniş bant gürültünün kullanımının eşik kaymasını azaltarak daha güvenilir eşik tayinine neden olduğu tespit edildi.Objective: This is a study which compares the effects of narrowband noise versus wideband noise on central inhibition values in individuals with hearing loss. Material and Methods: Thirty-seven subjects were primarily examined for otoscopic examination, pure tone audiometry, speech audiometry, and tympanometric evaluations; then demonstrated localization of hearing loss, type and degree of hearing loss. Similarly, pure tone thresholds were tested in three different conditions while applying narrowband and wideband noise as well as without any masking noise using contralateral route. Results: In cases with sensorineural hearing loss, at frequencies of 250, 500, 2000 and 8000 Hz; In cases with conductive hearing loss, the use of wideband noise at frequencies of 250,500 and 1000 Hz reduced the threshold shift, causing a statistically significant change in the thresholds (p<0.05). Conclusion: In our study, it was found that the use of wideband noise in conductive and sensorineural hearing losses decreased threshold shift and caused more reliable threshold determination

Mineral element uptake status of endemic Isoetes anatolica Prada & Rolleri populations from Bolu-Turkey

Isoetes genus is commonly known as the "quillworts" and considered to be "fern allies". There are about 200-250 species, with a cosmopolitan distribution but often scarce to rare. Isoetes genus members often grow in extremely sensitive aquatic environments such as temporary ponds, streams and lakes. They are therefore good indicators of environmental quality. Isoetes anatolica Prada & Rolleri is an endemic plant grows on calcareous sediment/soil on the edges of seasonal ponds located in a mountainous area near the southern coast of the Black Sea at 1400 m above sea level at Bolu, Turkey. In this study, mineral element uptake statuses of I. anatolica populations were studied on the background of plant-sediment/soil-water interactions. The study materials were collected from the place where this narrow endemic species only lives in the world (Abant Region, Bolu/Turkey) by using standard methods and plant and sediment/soil mineral element measurements (Al, B, Ca, Cu, Fe, K, Mg, Mn, Na, Ni and Zn) were done. ICP-OES was employed for the measurements during the study. Interrelations between mineral element contents in the sediment/soil, water and plant were discussed. The data revealed that I. anatolica is capable of accumulating considerable amounts of certain mineral elements (B, Ca, Mn and Na).Marmara University, Commission of Scientific Research Project (FEN-D-040712-0291

Normalızatıon of masseter VEMP and comparıson wıth cervıcal VEMP ın normal ındıvıduals

Abstract Objectıve The objective of this study is to obtain normative data of the masseter vestibular-evoked myogenic potential (mVEMP) test in healthy individuals without hearing loss and dizziness and to compare the responses with the cVEMP test. Methods Twenty healthy individuals (10 males and 10 females) aged 20–30 years without auditory and vestibular disorders participated in the study. First, mVEMP and then cVEMP tests were applied to the individuals who voluntarily participated in the study. Results Latency values of the air-conducted mVEMP were 15.90 ± 1.68 ms for P1 and 25.86 ± 1.48 ms for N1 and 9.96 ± 1.50 ms for interpeak latencies. P1N1 amplitude value was 97.89 ± 37.34 μV and asymmetry ratio (AR) was 0.13 ± 0.07. The normative data for the mVEMP threshold was found 84 dB nHL. According to the gender difference in mVEMP measurement parameters, the P1 latency of women was found shorter than the P1 latency of men at all stimulus intensities except 90 dB nHL. There was no statistically significant difference between mVEMP and cVEMP test results in all other severity and all parameters except P1 latency at 100 dB and interpeak latency at 100 dB (p > 0.05). Conclusıon In conclusion, it was the study findings suggest that obtaining normative data on mVEMP could be used as an auxiliary test in the evaluation of the vestibular and trigeminal pathway and the evaluation of patients with various peripheral and central vestibular disorders

Infrapopliteal Percutan Transluminal Angioplasty of Patients with TASC D Group Diabetic Foot Lesions According to the Transatlantic Inter-Society Consensus II

Aim: We aimed to evaluate the effectiveness of percutaneous transluminal angioplasty (PTA) in limb salvage in patients with diabetic foot disease and critical limb ischemia according to the Trans-Atlantic Inter-Society Consensus II (TASC) classification system for type TASC D infrapopliteal artery disease. Methods: We retrospectively reviewed the angiographic records of patients with diabetic food disease and critical limb ischemia who underwent PTA between January 2014 and December 2015. Patients with TASC D isolated infrapopliteal artery disease and followed up for 12 months were included in the study. Technical success and limb salvage rates at 12 months were evaluated. Results: During the study period, 72 patients were screened for study enrolment and 32 met the inclusion criteria. The overall initial technical success rate in PTA was 68.8%. Limb salvage rate was 72.7% at 12 months in patients who had technical success. Among the factors that affected initial technical success and limb salvage at 12 months, only length of occlusion was found to be significant. Conclusion: PTA shows an effective technical success and good limb salvage rates in di¬abetic patients with TASC D group of critical limb ischemia. PTA may be attempted as an alternative treatment in patients with critical limb ischemia rated unfit for surgery

Intervertebral disc heights and concavity index of the lumbar spine in young healthy adults

Objectives: The aim of this study was to investigate lumbar intervertebral disc heights and concavity index of the lumbar spine, and the influence of age, gender, weight, height and body mass index (BMI) on these parameters. Methods: The study was conducted on 150 health young subjects (age 18 to 27) without any disorder which affects the lumbar spine and the discs. Subjects underwent standard standing lateral lumbar radiography. Mann-Whitney U test and Spearman’s correlation test were used for statistical analysis. Results: Of the 150 subjects (age range, 18–27 years), 80 (53.3%) were women and 70 (46.7%) were men. Men presented higher lumbar disc values than women. In both genders, disc height increased from T12–L1 to L4–L5, and then decreased at L5–S1. The heights of all lumbar discs increased with age, weight, height and BMI in both genders. Women demonstrated a higher concavity index at L2, L3 and L4 vertebrae compared to men, whereas men showed a higher concavity index value at L5 vertebra. The concavity index of T12, L1, L2, L3 and L4 vertebrae decreased with age. Conclusion: Our results will serve as guidelines and references for further studies, radiologists and spinal surgeons. Keywords: concavity index; intervertebral disc; lumbar vertebrae; radiography, spin
