Efficacy of leukotriene antagonists as concomitant therapy in allergic rhinitis

The symptoms of allergic rhinitis result from an immunoglobulin E‐dependent mast cell activation cascade, marked by the release of inflammatory mediators, including histamine. Patients with perennial allergic rhinitis also have elevated levels of cysteinyl leukotrienes (CysLTs) in nasal lavage fluid. Histamine and CysLTs produce different responses in the pathogenesis of allergic rhinitis, and this study tested the hypothesis that the effects of combined antihistamine and leukotriene antagonist therapy would be more effective than antihistamine alone.

Effect of CPAP therapy on catathrenia and OSA: a case report and review of the literature

IntroductionCatathrenia is a rare, idiopathic, sleep-related respiratory condition characterized by irregular groans, which occur during prolonged expiration in sleep. The origins of catathrenia remain inexplicable, the long-term prognosis unexplained. Moreover, empirical treatment with neither pharmacological nor non-pharmacological approaches was satisfactory.Case reportWe report a case of catathrenia with concurrent obstructive sleep apnea complicated with pulmonary hypertension and reviewed the literature.DiscussionTreatment with nasal continuous positive airway pressure resulted in marked improvement of catathrenia, obstructive sleep apnea, daytime dyspnea, and pulmonary hypertension for our patient. We think that nasal continuous positive airway pressure can be an option for the treatment of this infrequent but sometimes very disturbing sleep disorder.

Videofluoroscopic evaluation of the swallowing function after supracricoid laryngectomy

This study was designed to evaluate the swallowing function in patients with supracricoid laryngectomy (SCL) compared to normal subjects and to search for the factors affecting postoperative aspiration. Ten patients who underwent SCL with cricohyoidopexy (CHP) for primary laryngeal squamous cell carcinoma were included in the study. The control group consisted of 13 normal adult volunteer men with similar ages. The swallowing act of the subjects was evaluated by using videofluoroscopy (VFS) and videolaryngostroboscopy (VLS). The movements of the larynx were measured with regard to the hyoid bone, mandible and vertebral spine. The patients with SCL-CHP, except for two who had slight aspiration, had effective and near normal swallowing regarding the measurements of the movements of the hyoid bone. They could tolerate a near-normal oral diet. We have observed that the preventive precautions for aspiration are preserving the superior laryngeal nerves, suturing and positioning the cricoarytenoid unit as anterosuperiorly as possible, early decannulation and early onset of swallowing rehabilitation; the risk factors for aspiration are advanced stage of cancer, postoperative radiation and shortening of bolus transit time. VFS is useful for the patients with postoperative aspiration, because it is the definitive technique for anatomical and physiological evaluation of swallowing. We consider that the parameters of VLS and VFS, such as tongue base-arytenoid contact, presence of bolus splitting, pseudoepiglottis function, maximal opening of the pharyngoeosophageal sphincter and total movement of hyoid bone are important criteria to evaluate swallowing.

Orbital exenteration : A dilemma in mucormycosis presented with orbital apex syndrome

Background Mucormycosis is an uncommon, rapidly progressive, commonly fatal, opportunistic, fungal paranasal sinus infection. The most critical decision in the management of rhino-orbital mucormycosis is whether the orbit should be exenterated. The literature fails to provide a broad base of information of how physicians determine the need for exenteration in daily practice. The decision for exenteration often depends on the judgment of the treating otolaryngologist. The authors report their experience and outline that orbital exenteration may not be mandatory in all cases of rhino-orbital mucormycosis. Methods The medical records from Celal Bayar University Medical Faculty Department of Otorhinolaryngology/Head and Neck Surgery were retrospectively searched from 1995 to 2007 for three cases with rhino-orbital mucormycosis, treated without orbital exenteration. Results All patients with rhino-orbital mucormycosis who were treated without exenteration survived. Conclusion The favorable outcome was attributable to rapid correction of the underlying medical condition; wide local excision and debridement of all involved and devitalized sinonasal and periorbital tissue, while establishing adequate sinus and orbital drainage; daily endoscopic assessment with multiple sinus debridement when necessary; daily irrigation of the involved areas; and high-dose i.v. amphotericin B.

Multidimensional assessment of voice and speech after supracricoid laryngectomy with cricohyoidopexy

This study was designed: to evaluate the vocal function in the patients with supracricoid laryngectomy (SCL) compared with normal subjects; to determine the factors affecting voice (such as number of arytenoid(s) preserved and movement of larynx and tongue base); and to determine the correlations between videolaryngostroboscopy, acoustic and perceptual parameters. Ten patients who underwent SCL with cricohyoidopexy for primary laryngeal squamous cell carcinoma were included into the study. Vocal function was investigated by means or videolaryngostroboscopy. Voice quality was assessed by means of objective acoustic analysis and subjective perceptual ratings by trained raters. Aberrant, incompetent, and rough mucosal wave was observed in the anterior and superior surfaces of arytenoids(s), the inferior part of tongue base and the lateral walls of the hypopharynx. The acoustic parameters were found to be significantly different from those of normal subjects. The values of perceptual scores were approximately within 50 per cent of normal range. The number of arytenoids spared did not affect acoustic or perceptual measurements. A rough, breathy, unpleasant but intelligible and acceptable voice could be obtained after SCL with cricohyoidopexy.

Impact of nasal polyposis on erectile dysfunction.

Background Our male patients with chronic rhinosinusitis with nasal polyposis (NP) declare a better sexual function after functional endoscopic sinus surgery (FESS) with polypectomy. This study was planned to conduct the first prospective, controlled trial evaluating the possible relation between erectile dysfunction (ED) and NP by subjective and objective parameters. Methods Thirty-three male patients with NP and thirty randomly selected male control subjects were evaluated. All subjects underwent assessments of nasal endoscopy, rhinomanometry, body mass index (BMI), Epworth Sleepiness Scale, full in-laboratory polysomnograpy and serum levels of glucose, thyroid hormones, lipid profile, and testosterone. ED was evaluated by the erectile function domain of the International Index of Erectile Function (IIEF-EF) subjectively and nocturnal penile tumescence (NPT) objectively. The NP group was reassessed 6 months after FESS. Results The mean age, BMI, and laboratory tests of the patients and the control subjects had no significant difference. The well-recognized risk factors for ED were eliminated. Preoperative evaluation of the patients revealed that ED was present in 34 and 24% of the patients by IIEF-EF and NPT, respectively, which was significantly higher than the control group (p = 0.009 and p = 0.018, respectively). There was a significant improvement of ED in the assessment of IIEF-EF and NPT postoperatively (p = 0.014 and p = 0.037, respectively). Conclusion ED was determined in a high percentage of patients with NP and significantly ameliorated after FESS. NP might present a risk factor in the development of ED.

Does maxillary arch remodeling exist in nasal polyposis

Background The potential transformation in the maxillary complex morphology is mostly complete during childhood. Recent studies suggest a nasal tissue remodeling both in the overlying mucosa and in the underlying sinus bone in nasal polyposis (NP). Our evaluation of computed tomography (CT) revealed that the maxillary arch is more flat and shallow in patients with chronic rhinosinusitis with NP. The purpose of this study was to determine the possible effects of NP to the maxillary arch morphology in adulthood and to investigate a possible remodeling of the maxillary bone during the course of NP. Methods A prospective study was performed on 25 patients. Grading of the polyps, acoustic rhinometry and rhinomanometry assessments, and CT scans were documented initially, 1 year after diagnosis, and 2 years postoperatively. Twenty-five subjects’ CT scans randomly selected from our CT database formed the comparison group. The plane angle between the maxillary alveolar processes (MAP) and the palatine process of the maxillary bone (MPP), and the depth of the maxillary arch of both groups were compared. Results The results pointed out that the maxillary arch was shallower and the bilateral angles between MAP and MPP were significantly greater than those of the comparison group in all evaluation periods. This difference was less at the end of the postoperative follow-up period. Conclusion Although it is a common belief that maxillofacial formation expires in childhood, this may not be the case under some special conditions such as NP in adulthood. NP might cause maxillary arch remodeling in adults.

13-93B3 Bioactive Glass: a New Scaffold for Transplantation of Stem Cell-Derived Chondrocytes

Abstract Research using animal models gives human trials hope for recovery in many fields of regenerative medicine, although they are sometimes poor predictors for human experiences. Our goal was to investigate whether rat chondrocytes, differentiated from adipose-derived stem cells, could be transplanted using a new, easily shaped, bioactive glass scaffold, and to show the immunohistochemical results. Intraperitoneal and retroperitoneal adipose tissue was extracted from 6 male Wistar albino type rats. The fatty tissue samples were fragmented and incubated. Chondrogenic differentiation was carried out and collagen type II, bFGF, and Sox-9 immunohistochemical characterization analysis was performed. Differentiated chondrocytes were implanted on 13-93B3 bioactive glass scaffolds and transplanted into the right ears of the rats. As control, only the biomaterial was transplanted into the left ears of the rats. After 1 month, the rats were sacrificed and transplantation areas were examined immunohistochemically. Histological examination of control samples from the left ears revealed that the biomaterial was covered with connective tissue, its general structure was preserved, and resorption of the scaffold had started. In specimens from the right ears, the biomaterial was covered with connective tissue, its structure was preserved, cartilage cells were present around the biomaterial, and the presence of cartilage tissue was demonstrated immunohistochemically. In conclusion, 13-93B3 bioactive glass scaffold contributed to the formation of new collagen and the survival of chondrocytes, and is a promising new biomaterial that will prove very useful in regenerative medicine.

The evaluation of pattern and quality of sleep in patients with chronic rhinosinusitis with nasal polyps

OBJECTIVE The goal of this study is to evaluate the impact of chronic rhinosinusitis with nasal polyps (CRSwNP) on sleep pattern and sleep quality before and after functional endoscopic sinus surgery using subjective and objective parameters. METHODS Twenty-two patients with CRSwNP were evaluated. All subjects underwent assessment by nasal endoscopy, rhinomanometry and computed tomography. Sleep pattern and sleep quality were evaluated by Pittsburgh sleep quality index (PSQI) and polysomnography (PSG). All patients were reassessed 6 months after surgery. RESULTS Nasal resistance decreased after the surgery (p<0.001). Postoperative PSQI scores were significantly lower than preoperative scores (p<0.001). The preoperative mean values of total apnea index and apnea-hypopnea index were 25.4 and 13.3, respectively. After surgery, the total apnea and apnea-hypopnea index had decreased significantly to 7.8 and 11.2, respectively (p=0.009 and 0.019, respectively). CONCLUSION In patients with CRSwNP, functional endoscopic sinus surgery significantly ameliorates sleep pattern and sleep quality. CRSwNP may be a predisposing factor for sleep related respiratory disorders.
