Endoscopic evidence of reflux disease in the larynx

Abstract Conclusion: The severity of laryngeal mucosal lesions in patients with gastroesophageal reflux disease (GERD) is significantly greater than in controls. A higher degree of laryngeal mucosal injury is documented in patients in whom GERD is associated with more advanced esophageal lesions. Objectives: (1) To confirm the presence of inflammatory lesions in the laryngopharynx of patients with GERD. (2) To analyze the relationship between the severity of laryngopharyngeal and esophageal lesions on the basis of the reflux finding score (RFS) and the Los Angeles (LA) scale of esophageal mucosal injury. Methods: The study included 92 subjects, among them 46 patients with GERD and 46 individuals without endoscopic evidence of esophageal lesions, qualified for routine endoscopy due to other indications. The endoscopic images of the inferior pharynx, larynx, and esophagus were analyzed during the video-endoscopic examination of the upper gastrointestinal tract. The laryngeal images were assessed according to RFS criteria and the numeric value of RFS was calculated. The degree of esophageal mucosal injury was described according to the LA scale. Results: Both global RFS score and the scores of all RFS parameters except the presence of granulomatous tissue were significantly higher in patients with GERD than in the controls. Patients in whom GERD was associated with more severe esophageal lesions (group B according to the LA scale) had significantly higher global RFS score and scores of all analyzed parameters of laryngeal injury except subglottic edema than individuals in whom the degree of esophageal involvement was classified as group A.

Summary Introduction Cartilaginous tumors of the head and neck are rare. The most frequent site is larynx and spheno-ethmoidal area. Chondroma of the nasal septum is very rare. Since its first description in the literature in 1842, only about 140 cases have been reported. The symptoms of nasal septum chondroma are nasal obstruction, headache and epistaxis. The treatment of choice is wide surgical excision. Aim The aim of our study was to show own, very rare case of septal nasal chondroma. Material and methods We described a case of septal nasal chondroma in the 39-year-old female. She reported nasal obstruction, headache of the frontal area for about 10 years. The CT examination showed the tumor mass in the right nasal cavity extending to the maxillary sinus and right orbit. The tumor was removed via the lateral rhinotomy. Histopathological examination revealed chondroma. No recurrence was noticed after 2 years of follow-up. Conclusions Chondroma should be taken in to consideration during the differential diagnosis of the septal nasal tumors.INTRODUCTION Cartilaginous tumors of the head and neck are rare.

Ocena wybranych biomateriałów do rekonstrukcji perforacji przegrody nosa

INTRODUCTION The septal nasal perforation is an important problem for the laryngologists and plastic surgeons. The reasons of septal nasal perforations are injuries, neoplasm, self-mutilation, chronic rhinitis, allergy, Wegener granuloma, sarcoidosis, tuberculosis, toxic metals (arsenic, chrome), some drugs (steroids), narcotizing agents (cocaine) and complications after endoscopic and septal nasal operations. The surgical treatment, especially in the cases of large septal perforation, is often difficult because of the atrophy of nasal mucosa and lack of suitable material for reconstruction. In the surgical treatment many of methods and reconstructive materials have been used. The following autogenous tissues were used in the reconstruction of septal perforation: alloderm, temporal fascia, septal and auricle cartilage, cranial periosteum, perichondrium, ethmoidal and hip bone. The defect of such materials is progressive resorption. For many years the suitable synthetic material for septal nasal reconstruction has been searched for. Among the biomaterials the following have been used without success: Dacron, porous polyethylene, dolomite, bioglass. The rejection of synthetic material was the reason of failure. The aim of our study was to evaluate two different biomaterials with proper mechanical and biological features for nasal cartilage replacement. MATERIAL AND METHODS We studied two types of biomaterials: biostable terpolymer PTFE/PVDF/PP and resorbable copolymer of glycolide and L-lactide (PGLA). The pilot studies were performed on two experimental animals (rabbits). The animals were operated in the general anesthesia. The biomaterials were implanted in the rabbit auricular cartilage because of its similarity to the septum and easy surgical access. Subperichondrically 1 x 1 cm fragment of the cartilage was removed. This fragment was then replaced with the biomaterial. The rabbits were painlessly sacrificed after 4 months of observation. RESULTS A very good integration of PGLA implant with auricular cartilage was observed. In the histological examination the lack of excessive inflammatory reaction as well as no cartilage necrosis were observed. CONCLUSIONS 4 months after implantation of PGLA in the rabbit auricular cartilage very good macroscopic and histological results were achieved.Summary Introduction The septal nasal perforation is an important problem for the laryngologists and plastic surgeons.

Frequency of IgE-dependent hypersensitivity to moulds in patients with chronic rhinosinusitis with polyps.

Introduction The complicated etiology of chronic sinusitis with polyps and frequent allergy to mould is established. Aim We aimed to investigate the frequency of the IgE-dependent hypersensitivity in this group of patients and prove the need of surgery in allergic chronic rhinosinusitis patients. Material and methods Forty-two patients (19 females, 23 males) aged 34–73 years (55 ±12.6 years), with chronic sinusitis with polyps were included into the study. Functional endoscopic sinus surgery, laryngological examination, sinus computed tomography scans, and smear from maxillary sinus for microbiological examination were done in all patients. Skin prick tests with common perennial and seasonal inhalant allergens, tIgE and sIgE against moulds were required. Results Thirty-two of 42 patients (71.4%) were allergic to at least one inhalant allergen. A mean concentration of total IgE was 241.2 ±186.3 kU/l (35.0–708.0 kU/l) and was lower in patients with fungal culture found in sinus mucin than in patients without fungal presence 75.1 ±54.6 kU/l vs. 284.3 ±204.1 kU/l. We found no difference in the number of positive skin prick tests in a group with and without fungal culture. None of patients with fungal culture found in sinuses presented a detectable level of mold sIgE. All patients with fungal vegetation in sinuses required at least two polypectomy procedures. Conclusions The total IgE concentration was significantly lower in patients with fungal presence in sinuses. Nasal polyps occurred more frequently in patients with fungal presence in sinuses.

Ekspresja niektórych molekularnych markerów immunohistochemicznych i ocena ich znaczenia prognostycznego w rakach płaskonabłonkowych jamy ustnej i wargi

Introduction Head and neck cancer treatment optimization and individualization has become possible due to the implementation of the prognostic and predictive molecular markers in diagnostics. Aim The aim of this study was an attempt to determine which of the investigated molecular markers may have prognostic and predictive value in head and neck cancers. Materials and Methods The paraffin blocks from 47 patients with oral and lip squamous cell carcinoma (SCC) after surgical treatment in the Institute of Oncology in Gliwice in the period of 1998–2002 were investigated. For immunohistochemical studies the DAKO monoclonal antibodies were used: p53, Ki67, Cyclin D1, Cathepsin B and Cox2-Cayman Chemical antibody. Staining reactions were evaluated at 400x magnification. The average percent of staining cells was estimated in every case in the groups of patients with (N+) and without (No) node metastases. The results were subsequently juxtaposed with selected clinical and histological parameters. Statistical analysis was performed with Mann-Whitney and Kruskal-Wallis tests and the log rank test with a significance level of 0.05 (p = 0,05). Results Significantly higher expression of Ki67 in N+ patients (p = 0,010) were recorded, although average staining in the group of treated and the group of unhealed patients was statistically insignificant. Cathepsin B expression ( 20%) was correlated with 3 year-long survival and a slight higher average staining (33,5%) in unhealed in comparison with treated patients (29,0%) was notified. Everage expression of p53 in unhealed patients (33,1%) was slightly higher than in treated ones (28,4%). Weaker Cyclin D1 expression (<10%) correlated with higher disease free survival. Average Cycline D1 staining in the groups of unhealed patients (19,6%) was higher than in the treated ones (12,0%). There were no significant differences in COX-2 staining in correlation with clinical and histological parameters. Conclusions Lower expression of Cyclin D1 and Cathepsin B in neoplastic cells correlated with higher percentage of disease free survival what suggests the prognostic value of these markers. Higher proliferation activity of primary tumor neoplastic cells correlated with node metastases what may has the predictive value in the course of the disease. The different markers expressions observed in the different oral cavity localizations confirm the necessity to select patients for further investigations with respect to uniform disease changes topography.

The influence of obstructive sleep breathing disturbances on echocardiographic and pulmonary haemodynamic parameters in patients with dilated cardiomyopathy.

BACKGROUND It is important to identify the clinical indicators of poor prognosis and treatable conditions that might contribute to the progression of heart failure (HF) and pulmonary hypertension (PH) in the group of patients with dilated cardiomyopathy (DCM) and concomitant obstructive sleep apnoea (OSA). AIM To evaluate the influence of OSA on echocardiographic and haemodynamic parameters in patients with DCM, and the outcome in long-term follow-up. METHODS We enrolled patients with DCM and severely impaired ejection fraction (EF < 30%). Each patient underwent polygraphy, echocardiography, and right heart catheterisation. Subjects were divided into groups based on the apnoea-hypopnoea index (AHI): > 0 and < 5 (group I), ≥ 5 and ≤ 15 (group II), > 15 and ≤ 30 (group III), and > 30 (group IV). We compared the OSA-free (AHI < 5) subjects with those with OSA (AHI ≥ 5). The evaluated clinical end-points were death and orthotropic heart transplant. RESULTS The study population comprised 51 patients. Mean EF was 22%; 59% of patients were suffering from OSA. The increased severity of OSA correlated with worse pulmonary haemodynamics. Patients with OSA had higher mean pulmonary arterial pressure and pulmonary vascular resistance than individuals without OSA (p = 0.044, p = 0.032, respectively). The highest chamber diameters assessed in echocardiography were found in group IV (p < 0.05). A total of 10 end-points occurred during follow-up (8.9 ± 5.1 months), with significant differences observed between groups I-IV and the highest rate in group IV (p < 0.001). CONCLUSIONS The increasing severity of OSA worsens the prognosis of DCM patients, independently of severe HF and coexistent PH. Systematic OSA screening in patients with HF might facilitate identification of individuals at high risk of progression of pulmonary haemodynamic impairment and end-point rate.

Reconstruction of the larynx after a resection of a huge chondrosarcoma

Chondrosarcoma of the larynx is a rare condition of still unknown pathogenesis. This tumor occurs usually between the sixth and seventh decade of life. Forty five years old patient was admitted to the ENT Department in Zabrze for a diagnosis of a slow growing tumor from about 3 years. The great unmovable tumor 2.5 cm/3 cm/3 cm was arising from the cricoid cartilage. The hist-pat result of the biopsy was cartilage. The patient did not agree on the proposed surgical treatment. After one year, in the MRI examination, the tumor sized 46 mm/37 mm/39 mm was found. The patient was again qualified for the operation and agreed for the proposed treatment. In general anesthesia, the tumor together with the part of trachea, cricoids and thyroid cartilages was resected. After excision the reconstruction was performed. During 10 months of the follow-up the patient remains free of the disease.

Head and neck lymphomas – a retrospective ten-year observation

Aim of the study Lymphomas are a heterogeneous group of tumours of lymphoid tissue in which there is an abnormal proliferation of cells of the lymphatic system. The literature notes a gradual increase in the incidence of this type of cancer in the whole population. The aim of the study was to evaluate whether the above tendency occurs in the head and neck area. Material and methods In the years 2005–2014, at the Otolaryngology and Laryngological Oncology Department of the Upper Silesian Medical Centre in Katowice, 77 cases of lymphoma were recorded, 58 of which were analysed in terms of location, histological type, age and sex of the patient, and the presence of risk factors. Results The vast majority of them were non-Hodgkin’s lymphomas (NHL) – 67.53%. Hodgkin’s lymphomas (HL) accounted for only a small fraction of diagnoses (7.79%). In terms of histopathological types, in most cases of NHL, there occurred diffuse large B-cell lymphomas (DLBCL) – 51.92%. The most common location was the lymph nodes, representing the location of the primary lesion in more than half of the cases. As regards the extranodal location, the Waldeyer ring dominated (54.54%) along with the palatal tonsil (40.90%). There has been a significant upward trend, especially in the incidence of NHL.

Sex-Related Cochlear Impairment in Cigarette Smokers

Background A number of studies have documented the influence of cigarette smoking on hearing. However, the association between sex and hearing impairment in smokers as measured by otoacoustic emissions (OAEs) has not been clearly established. The aim of this study was to analyze sex-specific effects of smoking on hearing via conventional and ultra-high-frequency pure tone audiometry (PTA), and OAEs, specifically spontaneous OAEs, click-evoked OAEs, and distortion-product OAEs. Material/Methods The study included 84 healthy volunteers aged 25–45 years (mean 34), among them 46 women (25 non-smokers and 21 smokers) and 38 men (16 non-smokers and 22 smokers). The protocol of the study included otoscopic examination, tympanometry, low-, moderate-, and ultra-high-frequency PTA, evaluation of spontaneous click-evoked (CEAOEs) and distortion-product otoacoustic emissions (DPOAEs), assessment of the DP-grams for 2f1-f2 (f1 from 977 to5 164 Hz), and input/output function at L2 primary tone level of 40–70 dB SPL. Results Smokers and non-smokers did not differ significantly in terms of their hearing thresholds assessed with tone audiometry. Male smokers presented with significantly lower levels of CEAOEs and DPOAEs than both male non-smokers and female smokers. Conclusions Smoking does not modulate a hearing threshold determined with PTA at low, moderate, and ultra-high frequencies, but causes a significant decrease in OAE levels. This effect was observed only in males, which implies that they are more susceptible to smoking-induced hearing impairment. Sex-specific differences in otoacoustic emissions level may reflect influences of genetic, hormonal, behavioral, and/or environmental factors.

Przydatność arytenoidektomii laserowej i laterofiksacji w leczeniu obustronnego porażenia fałdów głosowych

INTRODUCTION Bilateral vocal cord paralysis is caused by the damage of both recurrent laryngeal nerves. Such a pathology is not commonplace in the ordinary medical practice. It most often occurs as a complication after the thyroid gland surgery or thyroid re-surgery. In the case of bilateral vocal cord paralysis the treatment of the patient includes performing immediate tracheotomy or one of the surgeries aiming at widening the glottis because of dyspnea caused by the upper respiratory tract obstruction on the glottis level. AIM The comparison of efficacy and usefulness of two surgical techniques performed to widen the glottis – laser arytenoidectomy with posterior cordectomy and laterofixation. MATERIAL AND METHODS The research was carried out on the group of 57 patients suffering from bilateral vocal cord paralysis who, in the period of 1997–2009, underwent treatment in ENT Department in Zabrze Medical University of Silesia in Katowice. The first group included 36 patients who underwent laser arytenoidectomy with posterior chordectomy. The second group included 21 patients who underwent laterofixation. All of the patients treated with the laser arytenoidectomy with posterior cordectomy and laterofixation were subjected to respiratory system ventilation examinations before the procedure of widening the glottis and after the healing, at least 4 months after the surgery. Making self-evaluation, each of the patients answered a question concerning the improvement of their breathing comfort after the surgery. The patients from both groups underwent the vocal apparatus examination which included: subjective perceptive voice analysis according to GRBAS scale, videolaryngostroboscopy, evaluation of the maximum phonation time, self-evaluation survey of the post-surgical voice quality. RESULTS Among 57 patients suffering from bilateral vocal cord paralysis and operated by arytenoidectomy with posterior cordectomy (group I) and laterofixation (group II), a subjective improvement of the comfort of living was achieved which resulted in the possibility of making more physical activities. From the first group, 35 out of 36 patients were decannulated. In the second group, both patients who had previously undergone tracheotomy were successfully decannulated. There were no statistically significant differences in the increase of selected ventilation markers between the patients who underwent laser arytenoidectomy and those who underwent laterofixation. There were no substantial discrepancies in the perceptive voice analysis in GRBAS scale between the patients after laser arytenoidectomy and those treated with the technique of laterofixation. When asked about their post-surgical voice quality, the patients of the first and the second group rated their voice as worse than before the surgery. CONCLUSION Both surgical techniques, laser arytenoidectomy with posterior cordectomy and laterofixation, are efficient and useful in widening the glottis in the case of bilateral vocal cord paralysis. The improvement of the ventilation markers allows the growth in the comfort of living, restoration of the physiological respiratory tract and decannulation of the patients who had undergone tracheotomy. The deterioration of the voice quality is characteristic of both surgical techniques.Summary Introduction Bilateral vocal cord paralysis is caused by the damage of both recurrent laryngeal nerves.
