RESUMEN

The trefoil factor family (TFF) is a relatively new family of peptides. In some studies, an association between trefoil factors and inflammatory diseases of the nasal and paranasal sinuses has been suggested. However, it is still not clear whether there is a relationship between trefoil peptides and inflammation of the respiratory tract. The aims of this study are to determine the presence of TFF1, TFF2, and TFF3 in the nasal mucosa and investigate their relationships with inflammation by using rat models of various sinonasal inflammations. Nasal tampon, lipopolysaccharide, and ovalbumin were used to generate rat models of sinonasal inflammation, i.e., rhinosinusitis and allergic rhinitis. The study was conducted on seventy rats in seven groups, each with ten rats: four groups with rhinosinusitis, two groups with allergic rhinitis, and a control group. Histological evaluation of sinonasal mucosa from all rats was performed, and Trefoil factors were investigated using immunohistochemical methods. All three TFF peptides were detected in rat nasal mucosa by histological evaluation. No significant differences in the trefoil factor scores were observed among the study groups. A significant correlation between the TFF1 and TFF3 scores and loss of cilia was identified (p < 0.05). In conclusion, no direct relationship between sinonasal inflammation and TFF scores was observed. However, a possible association between the TFF and epithelial damage or regeneration in sinonasal inflammation can be suggested based on the correlation observed between the TFF1 and TFF3 scores and scores of cilia loss.

RESUMEN

We aim to demonstrate possible autonomic dysfunction based on salivary α-amylase measurements during and after the vertigo attacks associated with Ménière disease (MD) and benign paroxysmal positional vertigo (BPPV). Patients admitted to the emergency room with a diagnosis of vertigo attacks caused by either MD (n = 15) or BPPV (n = 9) constituted the study groups. The control group (n = 10) consisted of volunteer patients admitted to the emergency department with minor soft-tissue trauma. The first saliva samples were obtained immediately during the attacks and the second and third samples were obtained on the third and fifteenth days of the attack, respectively. In the controls, the first sample was obtained after admission to the hospital and the second sample was obtained on the third day. Salivary α-amylase levels were evaluated. The difference between salivary α-amylase levels in patients with MD and BPPV was not significant. The amylase value measured early after the BPPV attack was significantly lower than that of the controls (p = 0.008). Although not significant, an undulating pattern of salivary α-amylase levels was observed with both diseases. An autonomic imbalance could be partly demonstrated by salivary α-amylase measurement early after the attack in patients with BPPV. Therefore, amylase may be a promising marker that is worth further investigation.

RESUMEN

BACKGROUND: Rhinoplasty is a complex but commonly applied surgical procedure. Patient satisfaction is the least discussed but one of the most important determinants of surgical success. OBJECTIVES: Evaluation of the patient satisfaction together with surgeon satisfaction were the main goals of this study. The roles of anxiety, gender, age and follow-up period were also studied. PATIENTS AND METHODS: 53 eligible patients operated by the first two authors within the previous 2 years were enrolled in the study. The medical records were reviewed for demographic data as well as the details of the surgical procedure. Functional and esthetic satisfactions of the patients were evaluated by VAS and ROE respectively. Surgeon satisfaction was evaluated by VAS in crosswise manner. Anxiety was measured by STAI_s and STAI_t scales. RESULTS: The analysis concerning esthetic results as well as functional results did not reveal any significant difference between the two surgeons (p = 0.132, p = 0.43 respectively). ROE scores were significantly different among patients with "good" and "very good" functional results. The difference between surgeon satisfaction and patient satisfaction was found to be insignificant (p = 0.273). Correlation analysis yielded a positive correlation between STAI_I and STAI_II (Pearson r = 0.335, p = 0.014) but not between STAI scores and ROE scores. Moreover, there was no relation between anxiety scores and the functional results. Likely, gender as well as age, follow-up, and surgical technique were not found to have any effect on patient satisfaction either. CONCLUSION: Patient satisfaction is preferential in rhinoplasty. In our patient series, patient satisfaction was shown to be correlated with functional outcome but not with surgeon satisfaction. Anxiety was not found to have a significant impact on results of rhinoplasty. Our results should be interpreted cautiously keeping in mind that our patients' primary drive for rhinoplasty was functional.

RESUMEN

BACKGROUND: Voice may be affected during the period of pregnancy, especially in the third trimester. However, the exact mechanisms leading to the phonatory changes have not yet uncovered. AIMS: The aim of this study is to investigate the possible histological changes in the vocal cords of the pregnant rats in three separate trimesters. STUDY DESIGN: Animal experiment. METHODS: Twenty-five Wistar-Albino female rats were divided into four groups: control group, pregnancy day 7 (Group 1), pregnancy day 14 (Group 2) and pregnancy day 20 (Group 3). The laryngeal specimens were obtained under general anesthesia. Histological assessment was performed using Hematoxylin-eosin and toluidine blue. A stereological analysis of vocal cord tissue was performed using a NIS-Elements D32 Imaging Software. RESULTS: Lamina propria was observed to be edematous, and the lamina propria area was thickened starting from the second trimester. Glycosaminoglycans were observed to increase in the second trimester. Although none was encountered in the control, mast cells were observed in the lamina propria layer of the vocal cord starting in the muscular layer in the first trimester proceed to the subepithelial region as degranulated just before term. The covering epithelium remained unchanged throughout pregnancy. CONCLUSION: Lamina propria thickening may be attributed to both edema and increased glycosaminoglycans. The presence of mast cells in the cordal tissue may induce edema during pregnancy in rats.

RESUMEN

OBJECTIVES: We aimed to investigate the histologic effects of N-butyl-2-cyanoacrylate (NBCA) and metacryloxisulfolane (MS) comonomer on tracheal anastomosis in vivo on a rat model of tracheal resection and end-to-end anastomosis. STUDY DESIGN: Animal experiment. Rat model of tracheal resection and end-to-end anastomosis. SETTING: Animal laboratory. SUBJECTS AND METHODS: Tracheal resection and end-to-end anastomosis were performed in 28 Wistar albino rats. Rats were randomly divided into 2 groups: control (n = 14), in which anastomoses were performed with 8/0 Vicryl, and study (n = 14), in which NBCA and MS comonomer was used in addition to 8/0 Vicryl to perform anastomosis. Seven rats from each group were sacrificed on day 7 and the remaining on day 28 for gross and histologic examination. RESULTS: Indurations at the site of anastomoses were detected in all rats of study group. Slight narrowing at the site of anastomosis was observed in 8 rats of the study group and in only 1 of the control group. The difference was significant on day 28 (P = .021). The inflammatory cell infiltration was significantly increased in the study group on day 28 (P = .022). Epithelial regeneration was found to be worse in the study group on day 28 (P = .022). CONCLUSIONS: The use of NBCA and MS comonomer increased the inflammation in rat tracheal anastomosis with respect to inflammatory cell count and epithelial regeneration. So the use of NBCA and MS comonomer in tracheal surgery cannot be recommended yet in the light of our data.

RESUMEN

Eccrine spiradenoma is a benign tumor of sweat gland origin. Malignant eccrine spiradenoma is a rare neoplasm which almost always arises from a pre-existing spiradenoma lesion. In this article, we present a patient with malignant eccrine spiradenoma of the auricula with a prior diagnosis as benign eccrine spiradenoma. Although malignant transformation is usually associated with aggressive behavior, we did not detect recurrence or metastasis in four years of follow-up after performing wide excision.

RESUMEN

OBJECTIVES: To investigate the effects of n-butyl-2-cyanoacrylate on tracheal anastomoses in terms of increased tension and intraluminal pressure ex vivo. STUDY DESIGN: Ex vivo experimental study. SETTING: Tertiary referral center (Department of Otolaryngology). SUBJECTS AND METHODS: Thirty sheep tracheas were used. Four cartilage rings were resected from the tracheas that were 20 cm in length. End-to-end anastomoses were performed by using Vicryl only (group 1), Vicryl and n-butyl-2-cyanoacrylate (group 2), and n-butyl-2-cyanoacrylate only (group 3). The amount of force to break off the anastomosis and the amount of intraluminal pressure to arouse air leakage through the anastomosis were measured. RESULTS: The mean force required to break off was 171.9 ± 29.7 N in group 1, 164.8 ± 26 N in group 2, and 13.52 ± 2 N in group 3. The mean force required to break off in group 3 was significantly lower than those in groups 1 and 2 (P = .008 and P = .008, respectively). The mean pressure required to cause air leakage was 49.6 ± 9.1 mm Hg in group 1, 113 ± 14.4 mm Hg in group 2, and 15 ± 4.2 mm Hg in group 3. Group 2 was found to be more resistant to intraluminal pressure than groups 1 and 3 (P = .008 and P = .008, respectively). CONCLUSION: n-Butyl-2-cyanoacrylate had no significant effect on tensile strength. However, its application on the suture line provided extra pressure resistance ex vivo. We believe that further studies need to be conducted to investigate its long-term effects and histological impact on tracheal anastomoses in vivo.

RESUMEN

Lymphoma is one of the malignant non-squamous tumors involving the head and neck. Lymphomas in this region are mostly B-cell type in origin and usually seen in Waldeyer's ring. In this article, we report a 45-year-old female case of primary natural killer T cell lymphoma-nasal type involving the nasooropharynx and larynx. This is a very rare entity with poor prognosis.

RESUMEN

BACKGROUND: Cervicofacial emphysema may arise due to the leakage of air from a defect in the aerodigestive tract to the fascial layers of neck and face. Rarely, it may be caused by insufflation of air through the Stensen's duct. CASE REPORT: We present a case with diffuse facial, cervical and mediastinal emphysema due to playing a wind instrument immediately after a facial trauma. There was no mucosal defect or laceration noticed by examination which could explain the origin of the emphysema. Despite the widespread cervicofacial emphysema with mediastinal involvement, the patient significantly improved within 48 hours without any intervention. CONCLUSION: Even though cervicofacial emphysema ameliorates spontaneously, increased care must be taken, especially when there is pneumomediastinum and/or pneumothorax.

RESUMEN

OBJECTIVES: In this study we first aimed to assess the cochlear functions in children with Familial Mediterranean Fever. The second aim was to investigate the correlation between the hearing levels and some clinical features of Familial Mediterranean Fever including the duration of the disease, age at onset, genetic analysis and colchicine use. METHODS: Thirty-four children with Familial Mediterranean Fever and 27 age matched children were included in the study. Following otologic examination, all children underwent audiometric evaluation, including Pure Tone Average measurements and Distortion Product Otoaoustic Emission testing. Audiological results of the two groups were compared and correlation between the audiologic status and clinical parameters of the disease like the duration of disease, age at onset, mutations and colchicine treatment were studied. RESULTS: Pure tone audiometry hearing levels were within normal levels in both groups. Hearing thresholds of Familial Mediterranean Fever patients were found to be increased at frequencies 8000, 10,000, 12,500 and 16,000 (p<0.05). In otoacoustic emission evaluation, distortion products and signal-noise ratio of FMF children were lower in the tested frequencies, from 1400 Hz to 4000 Hz (p<0.05). Interaction of the disease duration and age of disease onset was found to predict hearing levels, distortion products and signal-noise ratios of children with Familial Mediterranean Fever (F value=2.034; p=0.033). CONCLUSIONS: To our knowledge this is the first study demonstrating cochlear involvement in children with Familial Mediterranean Fever which showed increased hearing thresholds at higher frequencies in audiometry together with decreased distortion products and signal-noise ratios demonstrated by distortion product otoacoustic emission testing. Similar studies must be carried out on adult patients to see if a clinical hearing impairment develops. The possible mechanisms that cause cochlear involvement and the effect of colchicine treatment on cochlear functions must be enlightened.

RESUMEN

Salivary gland neoplasms are rare in the pediatric age group. Pleomorphic adenomas in the submandibular gland are rarer. In this article, we present a seven-year-old female with a slowly growing mass in her right submandibular area. The firm, mobile and painless mass was about 2x3 cm in size and with bimanual palpation it was indiscriminated from the submandibular gland. Magnetic resonance imaging with contrast revealed a heterogeneous and minimally lobulated mass within the submandibular gland with clearly defined borders. Fine needle aspiration biopsy revealed a diagnosis of pleomorphic adenoma and we performed right submandibular gland excision under general anesthesia. The histopathological diagnosis was pleomorphic adenoma with sparse mitotic figures that may be interpreted as having a potential of malignant transformation. This patient who was followed up for one year without any complication is to our knowledge the youngest case cited in the English-language literature.

RESUMEN

OBJECTIVE: To assess cochlear involvement and hearing loss in patients with Behçet's disease (BD). METHOD: Forty-two patients with BD and 24 sex and age matched healthy subjects were included in the study. pure-tone audiometry including high frequencies (250-16000Hz) and DPOAE were performed to all participants. Results of the audiological evaluation were compared and correlation between the audiologic status and clinical manifestations of the BD were investigated. RESULTS: Bilateral sensorineural hearing loss was detected in 27 (64.3%) patients. Hearing thresholds were found to be higher in patients with BD at all of the frequencies except at 500Hz when compared to control group (p<0.05). The difference in the hearing levels tend to increase in high frequencies. Compared with control group, distortion products and SNR of the BD patients were lower in all of the tested frequencies (p<0.05) which indicates weaker outer hair cell motility. There was no correlation between the clinical manifestations and the audiological parameters. CONCLUSION: Even having hearing levels within normal limits in speech frequencies, increased hearing thresholds in high frequencies and decreased signal-noise ratios (SNR) in distortion product otoacoustic emission (DPOAE) indicate a cochlear involvement in patients with BD.
