The aim is to investigate the contribution of the PNIF test in daily clinical practices in the objective evaluation of the early postoperative functional results of septoplasty and the effect of the ...severity, direction, and type of nasal septum deviation on mean PNIF values. Nasal septum deviation (NSDs) of the cases were grouped according to the Mladina classification and the severity of NSDs. An objective evaluation of the nasal airway was conducted via a peak flowmeter device in the preoperative and postoperative first month. When examining the mean PNIF values according to genders, it was observed that the values determined in male cases in the preoperative and postoperative period were higher. In the intragroup evaluation performed according the Mladina classification, a statistically significant increase was observed in the preoperative and postoperative PNIF values of the cases in Types 1–4. In the intragroup evaluation performed according to the severity of NSD, there was a significant increase in the preoperative and postoperative PNIF values of the mild and moderate cases. When comparing the preoperative and postoperative PNIF values of the groups in terms of the severity of NSD, it was observed that there was a significant difference. The PNIF can be used in routine clinical practices to evaluate the septoplasty results objectively. In the evaluation of functional results, the change in the mean PNIF values may also vary according to the direction and severity of septum deviation and the Mladina classification other than age, gender and ethnic origin.
Background
The aim of the present study was to evaluate retrospectively the frequency of anatomical variations in sinonasal region, which were frequently seen in our cases, for whom coronal section ...paranasal computed tomography imaging (CPNCT) was taken, as well as the correlation of these variations with age and gender and correlations of identified anatomical variations with one another.
In the study, CBCT scans of a total of 1532 (825 males and 707 females) cases were evaluated in order to determine the prevalence of anatomical variations of the nasal cavity and paranasal sinuses. All the images were taken by a multi-detector CT device (Aquilion, Toshiba medical system, Tokyo, Japan).
Results
Most frequently detected three anatomical variations were septum deviation (79.7%), concha bullosa (40.9%), and ethmoid bulla (21.0%) according to the frequency order. When the frequency of anatomical variations was evaluated according to gender, septum deviation, concha bullosa, and anterior clinoid process pneumatization were more frequently observed in males and Onodi cell in females (
p
< 0.05).
When the relationships of the anatomical variations with one another were evaluated, it was found that the possibility of the presence of concha bullosa in the septum deviation cases and the presence of ethmoid bulla in the cases with Haller cell septum were higher (
p
< 0.05).
In terms of the anatomical variations that were evaluated by taking age as the independent variable, a statistically significant difference was observed in pterygoid process pneumatization, Haller cell, pneumatized crista galli, ethmoid bulla, and paradoxical middle concha between the adult and children age groups (
p
< 0.05).
Conclusion
In terms of the frequency of occurrence to various sinonasal region variations, statistically significant differences were observed between both genders and age groups. The correlations of the detected variations with each other were also remarkable. Consequently, it is believed that comprehensive studies and serious objective evaluations evaluating the change of frequency of anatomical variations according to age and gender besides their correlation with each other are required.
Objectives: The study aimed to evaluate subjective and objective results after septorhinoplasty and to investigate the correlations between NOSE and SNOT-22 scales and saccharin clearance test (SCT) ...results. Patients and Methods: One hundred patients (37 males, 63 females; mean age: 26.4±8.4 years; range, 18 to 56 years) with nasal septal surgery indication were included in the study between January 2017 and January 2019. A SCT was applied to all cases preoperatively and in the first postoperative month, and SNOT-22 and NOSE questionnaires were filled. Results: No relationship was detected when the relationship between preoperative SCT and NOSE and SNOT-22 scores was evaluated. However, there was a statistically significant correlation between preoperative SNOT-22 scores and postoperative SCT values in 26% of the cases (r=0.260). Similarly, if the preoperative NOSE and SNOT-22 scores of the cases are low, it should be expected that the SCT value measured at the first postoperative month will be low, with a probability of 28% and 26%, respectively. As the preoperative NOSE value of the patients increased, the SNOT-22 value increased by 57.9% and 27.6%, respectively. Similarly, as the postoperative NOSE values increased, the postoperative SNOT-22 values increased by 51.8%. A positive relationship was found in all these bilateral correlations. According to the results obtained, the NOSE and SNOT-22 scores were 93% accurate and 98% acceptable. Conclusion: Although the statistically significant relationship between SCT results in the postoperative period and SNOT-22 and NOSE is a remarkable finding, there is a need for future studies that also evaluate long-term results to make more precise comments on this issue.
Nilotinib has very few side effects, including neutropenia, thrombocytopenia, cardiotoxicity, high pancreatic lipase, ischemia, and vascular occlusion. We aimed to investigate whether short-term ...administration of nilotinib had ototoxic effects in rats.
Wistar-albino rats were categorized into three groups: group C (administered 0.25 mL of distilled water, no nilotinib), group N-20 (administered 20 mg/kg/day of nilotinib dissolved in distilled water), and group N-50 (administered 50 mg/kg/day of nilotinib dissolved in distilled water). A single dose was administered once per day, at the same hour, over 21 days. Auditory brainstem response (ABR) thresholds were recorded on day 0 and day 21.
There were no changes in ABR threshold values obtained on day 0 (baseline) and on day 21 across all three groups. A statistically significant difference was not found in terms of the mean latency of waves V and III, interpeak latency values of waves III-V, and amplitude ratios of waves III-V and V/Va at baseline and on day 21 across all three groups on within-group or between-group evaluation.
Consequently, further studies are needed that involve different drug doses, prolonged administration of drugs, as well as distortion otoacoustic emission test for the evaluation of cochlear activation and ABR. Furthermore, histopathological studies are needed to indicate whether the cochlea is affected to prove that nilotinib has definitively no ototoxic effect.
Objective: Chronic otitis media (COM) is a multifactorial disorder, the pathogenesis of which has yet to be fully elucidated. Numerous aetiological factors, including genetics, eustachian tube ...dysfunction, autoimmunity, infection, osteoclastic activity, cytokines, endotoxins, and products of lipid peroxidation resulting from oxidative stress, have been proposed to explain the chronic inflammation which lies at the heart of the disorder. The aim of this study is to investigate a possible relationship between the pathogenesis of COM and polymorphism within the paraoxonase 1 (PON1) gene. Methods: We investigated 49 patients admitted to the Otorhinolaryngology Department and diagnosed with COM between September and November 2017. The control group consisted of 51 healthy individuals. Polymerase chain reaction (PCR) – restriction fragment length polymorphism (RFLP) methods were used to genotype the PON1 Q192R (rs662) polymorphism. Results: When the case and control groups were compared in terms of the existence of PON1 (Q192) polymorphism, there was no statistically significant difference between the groups (p=0.166, p>0.05). When intergroup comparison was performed on the type of PON1 (Q192) polymorphism, there was also no statistically significant difference (p=0.261, p>0.05). Conclusion: The present study is the first known study in which PON1 polymorphism has been examined in cases of COM. The results of our study failed to indicate a statistically significant relationship between PON1 polymorphism and COM. However, it is important to note that the higher rate of 192RR polymorphism within the control group control may indicate a protective effect in COM.
Objectives: Hypericum perforatum L. (HP) is among the oldest used and most comprehensively studied medicinal herbs. Anti-inflammatory activities of different Hypericum extracts on external auditory ...canal and also in the prevention of tympanic membrane perforation and myringosclerosis were investigated experimentally in the animal model. This study was to investigate whether or not intratympanic injection of H. perforatum L. in the middle ear of the rats causes ototoxicity, via auditory brainstem response (ABR). Materials and Methods: Rats were assigned to three groups as Group C, S, and D. Excessive external auditory canal edema developed in the rats in Group D as of the 5th day and Group D was excluded from the study by considering that ABR records could be affected. Results: A statistically significant difference was observed mean latency values of the wave V and III at the baseline and on the 7th day in Group S (P < 0.05). A significant shortening was calculated in the interpeak mean latency values of the waves III-V at the baseline and on the 7th day in Group S (P < 0.05). A statistically significant difference was observed between the baseline III-V wave interpeak mean latency values in the between-group evaluation on the 7th day (P < 0.05). A statistically significant difference was detected in the mean values of the wave V/Va amplitude ratios at the baseline and on the 7th day in Group S (P < 0.05).In the between-group evaluation, a statistically significant difference was found in the mean values of the wave V/Va amplitude ratios on the 7th day (P < 0.05). Conclusion: The results of the study conducted in accordance with the hypothesis point out that the intratympanic injection of H. perforatum L. may have an ototoxic effect.
Neurogenic inflammation plays a role in the pathophysiology of allergic rhinitis. Highly effective in reducing the sensory irritation caused by some substances, strontium salts directly affect C-type ...nerve fibers. The aim of this study was to compare the efficacy of mometasone furoate and strontium chloride on early-phase symptoms in a rat model of allergic rhinitis. Wistar albino rats (n = 24) were randomly divided into three groups: the mometasone group, receiving 1 μg mometasone furoate (2 µl/site); the strontium 3% group, receiving 3% strontium chloride (2 μl/site); and the strontium 5% group, receiving 5% strontium chloride (2 μl/site). To induce significant nasal symptoms of allergic rhinitis, 5 µmol of histamine dihydrochloride (HDC) (2 µl/site) was administered. Symptoms of allergic rhinitis were recorded as frequencies of sneezing and nasal rubbing during a 15-minute interval. On days 1 and 2, respectively, 0.9% sodium chloride (NaCl) (2 μl/site to each nasal cavity) and HDC were administered in all of the study groups. On days 3 and 4, the study drugs were administered 10 and 30 minutes before the administration of HDC. On day 5, the study drugs were administered 10 minutes after the administration of HDC. The results of the present study revealed that when strontium chloride or mometasone furoate was administered 30 minutes before the onset of symptoms, a significant decrease was observed in sneezing and nasal rubbing. The number of sneezing occurrences was significantly lower and the number of nasal rubbing occurrences was higher in the strontium 3% group compared to the groups in which mometasone furoate and 5% strontium chloride were administered after onset of symptoms. Recent studies have investigated the efficacy and safety of strontium chloride nasal drops compared with common pharmacologic treatments of allergic rhinitis. These studies have revealed that allergic rhinitis can be successfully and safely treated with strontium-chloride-containing products, thus offering a potential new treatment strategy.
