The effect of Ramadan fasting on nasal mucociliary activity and peak nasal inspiratory flow.

PURPOSE: In this study, we aimed to investigate the effect of Ramadan fasting (RF) on nasal mucociliary clearance (MCC) and peak nasal inspiratory flow (PNIF). METHODS: Sixty-two (41 male and 21 female) healthy subjects who stated that they would fast continuously during the month of Ramadan were included in this prospective study. Day 0 (baseline), 1st day (after one day of RF), and 29th (after 29 days of RF) nasal mucociliary clearance time (MCT) with saccharine test and PNIF values were determined. Subject weights (SW) were measured on Day 0 and Day 29. The obtained data were analyzed statistically. RESULTS: The mean of SW on day 0 was 78.53 ± 10.95 kg, and the mean of SW on Day 29 was 78.69 ± 10.87 kg. There was no significant difference in terms of SW (p = 0.251, p > 0.05). A significant difference was found between the MCT and PNIF values measured on different study days (p < 0.05). The MCT values for Day 29 were significantly higher than the values for other days (p < 0.05). There was no significant difference between the MCT values on the first day and the baseline (p = 0.891, p > 0.05). The PNIF values for Day 29 were significantly higher than the values for other days (p < 0.05). The PNIF values on the first day were significantly higher than the baseline (p = 0.008, p < 0.05). CONCLUSION: The present study showed that RF leads to MCT prolongation and PNIF increase. Ramadan fasting causes deterioration in nasal airway defense and improvement in nasal respiration.

The Onlay Rotated Flap (ORF): An Original Technique for Nasal Tip Plasty.

OBJECTIVE: The reshaping of the nasal tip in rhinoplasty according to the expectations of the patient and the surgeon is called tip plasty. in this article, the onlay rotated flap (ORF) is presented as a new technique for reshaping, supporting, and projecting the nasal tip without any resection or grafting. METHODS: Thirty-two patients (26 female and 6 male) were included in the study retrospectively. Primary rhinoplasty with ORF was performed to all patients. The follow-up period was between 9 and 12months. The nasal tip projection (NTP) with Goode method and nasal tip rotation (NTR) according to nasolabial angle were calculated in standardized preoperative and postoperative(6th month) photographs with image J. SPSS Version 21.0 was used for statistical analysis. RESULTS: There were no complications resulting from our procedure. There were no visible tip flaps, no distortion, no asymmetry, and no alar retraction. Revision surgery was not required in any patient. The preoperative and postoperative means of nasolabial angle (Mean ± SD) were 92.06 ±â€Š7.73° and 99.71 ±â€Š6.06°, respectively. The preoperative and postoperative means of NTP (Mean ± SD) were 0.535 ±â€Š0.041 and 0.57 ±â€Š0.386, respectively. The postoperative nasal tip rotation and NTP values of the ORF procedure were found to be statistically significantly higher than the preoperative values (P < 0.05). CONCLUSIONS: The ORF technique is another alternative for achieving adequate nasal tip definition and projection and has many advantages and very successful postoperative results. The alar retraction was not encountered in our technique and this is the superior aspect of our technique over similar methods described in the literature.

Effects of the acute exposure to the electromagnetic field of mobile phones on human auditory brainstem responses.

The purpose of this study was to evaluate the short-term effects of the electromagnetic fields (EMF) of mobile phones on human auditory brainstem responses. This prospective study of healthy adults evaluated the influence of EMF. Eighteen healthy adult volunteers participated in this study. Mobile telephones emitting signals in the region of 900 MHz and with the highest SAR value of 0.82 W/kg were positioned in direct contact to the right ear, which was exposed to the phone signal for 15 min before and after ABR testing with click stimuli of 60 and 80 dB nHL intensities. The latencies of the waves and interwave latencies were measured on screen by an experienced audiologist. The differences of the mean latencies of waves I, III and IV were not significant in initial and post-exposure ABR measurements at both 60 and 80 dB nHL stimulus levels ( P >0.05). Similarly, differences of the mean interwave intervals I-III, I-V and III-V remained insignificant at the initial and postexposure ABR measurements at stimulus levels of both 60 and 80 dB nHL ( P >0.05). Acute exposure to the EMF of mobile phones does not cause perturbations in ABR latencies. However, these negative results should not encourage excessive mobile communication, because minor biological and neurophysiological influences may not be detectable by the current technology.

Marble impaction in the nasopharynx following oral ingestion.

Foreign body ingestion is an important emergency occurring in childhood. In this article, we report the case of a 5-year-old girl with marble impaction in the nasopharynx, which had not been discovered by routine X-rays of the chest and abdomen at the time of ingestion. The patient presented 4 months after the event with typical symptoms of adenoid hypertrophy and sinusitis, and the diagnosis was established on the basis of a plain film of the nasopharynx. This rare situation is potentially dangerous, since the foreign body may descend and cause sudden airway obstruction. Therefore, in all cases with vanishing foreign bodies in the aerodigestive system, nasopharyngeal impaction and its fatal consequences should be kept in mind and endoscopic examination of the region should be considered.
