Turkish Guideline for Diagnosis and Treatment of Allergic Rhinitis (ART).

OBJECT: To prepare a national guideline for Otorhinolaryngologist who treat allergic rhinitis patients. METHODS: The study was conducted by three authors, namely the writing support team. The support team made the study plan, determined the writing instructions, chose the subgroups including the advisory committee, the advisors for authors and the authors. A workshop was organized at the very beginning to explain the details of the study to the team. Advisors took the chance to meet their coworkers in their subgroups and determined the main headings and subheadings of the guideline, together with the authors. After key words were determined by the authors, literature search was done in various databases. The authors keep in touch with the advisors and the advisors with the advisory committee and the support group at every stage of the study. National and International published articles as well as the abstracts of unpublished studies, imperatively presented in National Congresses, were included in this guideline. Only Guideline and meta-analyses published in last seven years (2013-2017) and randomized controlled studies published in last two years (2015-2017) were included. After all work was completed by the subgroups, support team brought all work together and edited the article. RESULTS: A detailed guideline about all aspects of allergic rhinitis was created. CONCLUSION: The authors believe that this guideline will enable a compact and up-to-date information on allergic rhinitis to healthcare professionals. This guideline is the first in the field of Otolaryngology in Turkey. It should be updated at regular intervals.

The effects of 4-aminopyridine and methylprednisolone on recovery of the facial nerve crush injury.

OBJECTIVE: 4-Aminopyridine (4-AP) is a potassium channel blocker that enhances nerve excitability. In this study, rat models that have facial nerve crush injury (FNCI) were grouped and treated with methylprednisolone (MP), 4-AP, and a combination of these two drugs. Electrophysiologic and histopathologic outcomes of these groups will be compared with a control group. MATERIALS AND METHODS: Thirty healthy male Wistar rats (mean weight of 265 g) were used in this study. The rats were randomly divided into five groups with six subjects in each: Group 1 (sham group), Group 2 (control group), Group 3 (MP group), Group 4 (4-aminopyridine group), and Group 5 (4-AP + MP group). All groups except the sham group underwent crush injury to the right facial nerve. Electrophysiologic and histologic recovery was recorded three weeks postoperatively. RESULTS: The 4-AP group and the combined group had a more significant recovery at Nerve Excitability Thresholds (NET) at the end of three weeks. The methylprednisolone group and the control group had a minimal recovery of NET. Histologically, when compared with the control group, the combined group was the only group that had significant recovery at all three of axonal degeneration, axon diameter, and myelin thickness. CONCLUSION: In this experimental study, we demonstrated that a combination treatment of 4-AP and MP is more effective in the recovery of peripheric FNCI than in the no-treatment control group and in the 4-AP- or MP-alone groups. Moreover, our results suggested that 4-AP can be a potent alternative to MP in the treatment of the FNCI. LEVEL OF EVIDENCE: N/A.

Does the reduction of inferior turbinate affect lower airway functions?

INTRODUCTION: Although the nose and lungs are separate organs, numerous studies have reported that the entire respiratory system can be considered as a single anatomical and functional unit. The upper and lower airways affect each other either directly or through reflex mechanisms. OBJECTIVE: In this study, we aimed to evaluate the effects of the radiofrequency ablation of persistent inferior turbinate hypertrophy on nasal and pulmonary function. METHODS: Twenty-seven patients with bilateral persistent inferior turbinate hypertrophy without septal deviation were included in this study. All of the patients were evaluated using anterior rhinoscopy, nasal endoscopy, acoustic rhinometry, a visual analogue scale, and flow-sensitive spirometry on the day before and 4 months after the radiofrequency ablation procedure. RESULTS: The post-ablation measurements revealed that the inferior turbinate ablation caused an increase in the mean cross-sectional area and volume of the nose, as well as in the forced expiratory volume in 1s, forced vital capacity, and peak expiratory flow of the patients. These differences between the pre- and post-ablation results were statistically significant. The post-ablation visual analogue scale scores were lower when compared with the pre-ablation scores, and this difference was also statistically significant. CONCLUSION: This study demonstrated that the widening of the nasal passage after the reduction of the inferior turbinate size had a favorable effect on the pulmonary function tests.

Albuminuria in Pediatric Patients With Adenotonsillar Hypertrophy.

The relationship between intermittent nocturnal hypoxia and albuminuria in pediatric patients with adenotonsillar hypertrophy was evaluated in this prospective study. Fifty children with grade 3 to 4 adenotonsillar hypertrophy scheduled for adenoidectomy and/or adenotonsillectomy were selected for study group. Fifteen patients with adenotonsillar grade 1 to 2 or adenotonsillectomized subjects in a similar range of sex, age, and body mass index scheduled for other surgeries were selected for control group. All children were monitored using finger pulse oximeter during the night before surgery. At the day of surgery, first morning urine samples were sent to the laboratory for analysis of albuminuria.Albuminuria was determined in 8 (16%) patients in study group and 1 (6.7%) patient in control group. This difference between groups was determined not to be statistically significant (P > 0.05). None of the pulse oximetry parameters was also found to be associated with albuminuria statistically (P > 0.05). However, the adenoid grade was observed to be associated with albuminuria (P = 0.011).This study revealed no relationship between albuminuria and intermittent hypoxia in children, although previous studies have reported that intermittent hypoxia causes albuminuria in adults. On the contrary, the adenoid grade was found to be in association with albuminuria. The reason seems to be unclear because of the lack of studies investigating albuminuria in children with adenotonsillar hypertrophy. However, inflammatory mediators arising from adenoid tissue may cause increase in renal capillary permeability and urine albumin excretion.

Sonographic scoring of solid thyroid nodules: effects of nodule size and suspicious cervical lymph node.

INTRODUCTION: Ultrasound is the most frequently used imaging method to evaluate thyroid nodules. Sonographic characteristics of thyroid nodules which are concerning for malignancy are important to define the need for fine needle aspiration biopsy or open surgery. OBJECTIVE: To evaluate malignancy risk of solid thyroid nodules through sonographic scoring. The effects of nodule size ≥2cm and associated pathologic cervical lymph node in scoring were examined in addition to generally excepted suspicious features. METHODS: Medical data of 123 patients underwent thyroid surgery were reviewed, and 89 patients (58 females, 31 males) were included in the study. The presence and absence of each suspicious sonographic feature of thyroid nodules were scored as 1 and 0, respectively. Total ultrasound score was obtained by adding the positive ultrasound findings. Differently from the literature, nodule size ≥2cm and associated pathologic cervical node were added in scoring criteria. The diagnostic performance of nodule characteristics for malignancy and the effect of total US score to discriminate malignant and benign disease were calculated. RESULTS: A significant relationship was found between malignancy and hypoechogenity, border irregularity, intranodular vascularity, and microcalcification (p<0.05). Pathologic cervical node was observed predominantly in association with malignant nodules. Positive predictive value of suspicious cervical node for malignancy was 67%, similar to microcalcification. Nodule size ≥2cm was not distinctive for diagnosis of malignancy. The number of suspicious sonographic features obtained with receiver operating characteristic analysis to discriminate between malignant and benign disease was three. CONCLUSION: Sonographic scoring of thyroid nodules is an effective method for predicting malignancy. The authors suggest including associated pathologic node in the scoring criteria. Further studies with larger cohorts will provide more evidence about its importance in sonographic scoring.

Anatomic Variations in Paranasal Sinuses of Patients With Sinonasal Polyposis: Radiological Evaluation.

OBJECTIVE: Although sinonasal anatomic variations have been postulated as a risk factor for sinus disease, the role of anatomic abnormalities in the pathogenesis of nasal polyps is still unclear. This study was conducted to examine the association of sinonasal polyposis with anatomic variations. METHODS: The paranasal sinus computerized tomography scans of 155 patients with sinonasal polyposis were examined retrospectively from January 2012 to 2014 in a tertiary care hospital. Paranasal sinus computerized tomography of 100 patients without complaints and signs of sinus disease were also included to serve as control group. The incidence of anatomic variations was evaluated. The sinonasal polyposis and control group data was compared statistically. RESULTS: The incidence of the septal deviation, concha bullosa, Agger nasi, frontal sinus hypoplasiaand accessory sinus ostium in healthy subjects, and sinonasal polyposis patients revealed statistically significant difference. The mentioned variations were found significantly higher in sinonasal polyposis patients (P = 0.000, P = 0.000, P = 0.001, P = 0.002, and P = 0.035 respectively) and may be predisposing for this pathology. CONCLUSION: Considering the results obtained, the presence of septal deviation, concha bullosa, Agger nasi cell, frontal sinus hypoplasiaand accessory sinus ostium may play role in pathogenesis of sinonasal polyposis.

Total Closure of Enlarged Tracheoesophageal Puncture with Septal Button: Long-Term Results.

Tracheoesophageal puncture enlargement in laryngectomized patients is a significant problem due to complications such as aspiration pneumonia. There are several management methods including conservative and nonconservative techniques. A total closure of the enlarged tracheoesophageal puncture is needed in some cases when conservative approaches have failed. At this point, the insertion of a silicone septal button in the puncture site is a useful, inexpensive, and simple technique. The follow-up of 4 patients managed with this technique revealed satisfactory long-term results.

Is the tragal cartilage necessary for type 1 tympanoplasties?

The use of cartilage grafts in tympanoplasties is recommended in cases with a higher probability of failure. Many grafting techniques have been reported, including palisade, cartilage island, and cartilage shield grafts. Cartilage minimizes the inflammatory tissue reaction, ensures resistance against infection during the recovery process, and provides good support against the retraction by virtue of its rigidity.This study compared the anatomic and functional results of conchal cartilage, tragal cartilage, and temporal muscle fascia grafts in primary type 1 tympanoplasty. Between January 2007 and January 2011, 79 patients with subtotal dry tympanic membrane perforation and an intact ossicular chain underwent primary type 1 tympanoplasty in our clinic. The postoperative perforation closure ratios, air and bone pure tone averages, and mean air-bone gap (ABG) in the 3 groups were compared with the preoperative values. The improvement in the mean ABG was assessed.The perforation closure ratio was 80.6%, 100%, and 88.5% in the muscle fascia, conchal cartilage, and tragal cartilage groups, respectively, and the mean increase in the ABG was 5.7, 8.9, and 9.7 dB, respectively.The island graft with cartilage perichondrium, which has recently become popular, can be also used in type 1 tympanoplasty. Because it does not require a second incision, conchal cartilage can be used routinely in tympanoplasties performed via a postauricular approach.

Efficacy of anti-adhesive barriers in secondary thyroidectomy: an experimental study.

HYPOTHESIS: This study was conducted to compare the effectiveness of two anti-adhesive barriers (Seprafilm and Interceed) for reducing adhesions after thyroidectomy in a rat model. The anti-adhesive barriers are suggested for use in repeated surgeries in general and the gynecologic fields in particular. STUDY DESIGN: Controlled, randomized study. METHODS: Twenty-eight male Wistar Albino rats that underwent right subtotal thyroidectomy were randomly assigned to three groups. One group received Seprafilm (n = 10), and the other received Interceed (n = 10) as anti-adhesive barriers. The third group was the control group (n = 8). At postoperative day 14, the rats were killed under general anesthesia, and the surgical fields were evaluated for the adhesion formation. The extent of the adhesion formation is scored from 0 (no adhesions) to 2 (fibrous adhesions that required sharp dissection). Histopathologically, chronic inflammation, histiocyte, fibroblast, fibrosis, collagen, vascularization, granuloma, giant cell, and fat necrosis were examined. RESULTS: All the subjects in the control group, 7 of 10 in the Interceed group, and 4 of 10 in the Seprafilm group needed to be dissected bluntly or sharply. There was significant difference between the Seprafilm and the control group (P < .05) whereas there was no significant difference between the Interceed group and the control group (P > .05). When examined histopathologically, the criteria showing adhesion, such as fibrosis, fibroblast, and collagen were higher in the control group compared with the Seprafilm and Interceed groups. There was no significant difference between the Seprafilm and Interceed groups, whereas a significant difference was found between these two groups and the control group. CONCLUSION: This study suggests that both Seprafilm and Interceed decrease the incidence of posthyroidectomy adhesions in a rat model. Both agents showed no foreign body reaction.

Tuberculous ulcer of the tongue: a case report.

A 33-year-old male patient was admitted to our hospital with a painless ulcer on the tongue. The lesion was 2 x 3 cm in size, necrotic, and whitish in the anterior part of the ventral surface of the tongue. On further investigation, pulmonary tuberculosis was diagnosed. Cultures of the biopsy specimen and the sputum revealed acid fast bacilli. Histopathologic examination of the biopsy specimen showed tubercles consisting of epithelioid granulomas with caseous necrosis and Langhans giant cells. The lesion was thought to be an extrapulmonary manifestation of pulmonary tuberculosis. Antituberculous therapy was initiated and the ulcer regressed after two months. In the differential diagnosis of nonhealing oral ulcers, tuberculosis should also be considered, especially in patients living in a high risk country for tuberculosis.
