Analysis of most common CFTR mutations in patients affected by nasal polyps.

Nasal polyps, a chronic inflammatory disease occurring in the nose and para-nasal sinuses, result from several different causes, including cystic fibrosis (CF). Forty-four patients affected by nasal polyps were admitted to the Department of Otolaryngology, Lublin University School of Medicine, Lublin, Poland, and screened for the most-commonly identified CFTR mutations [DeltaF508, G542X, N1303 K, 1717-1 (G to A), W1282X, G551D, R553X and DeltaI507] by applying the INNO-LIPA CF2 test strips. None of the patients had symptoms that allowed for the diagnosis of CF, including the negative sweat test. We detected 5 of 44 (11.4%) carriers of the CFTR mutations. All patients positive for this test were heterozygous carriers of DeltaF508. In the control group, only 1 of 70 (1.4%) cases showed DeltaF508 heterozygosity. The frequency of DeltaF508 mutation herein reported was significantly higher than in the control group (P = 0.0312) and in the general Polish population as well (P = 0.0059). Our data suggest that a heterozygous manifestation of the DeltaF508 may exist in a selected group of patients affected by nasal polyps, who have no other clinical features of CF.

[Epithelial cell proliferation in nasal polyps].

The mechanism stimulating the growth of nasal polyps remains unclear. The fact that nasal polyps formation is connected with increase of the epithelial surface suggests that the dysregulation of epithelial cell proliferation takes part in their pathogenesis. Furthermore, macroscopically nonsuspected nasal polyp, usually benign tissue lesion, occasionally may be misdiagnosed such as neoplasm. Only a few studies have undertaken the subject of cell proliferation in nonneoplastic respiratory epithelium. We examined 30 nasal polyps specimens by immunohistochemistry to recognize the expression of nuclear antigen present in proliferating cells, using rabbit anti-human Ki-67 antigen. Our study revealed significantly higher Ki-67 index in nasal polyps than in nasal mucosa (p < 0.005, tab.I). Based on this findings it seems that increased epithelial cell proliferation and chronic inflammation generate the lesion of the nasal mucosa leading to nasal polyps formation.

[Chronic sinusitis therapy with antibiotics (axetyl cefuroxym, clarithromycin) and steroid (prednisone)].

We started therapy sinusitis of our patients with antibiotics cefuroxime axetil (Zinnat, GSK), clarithromycin (Klacid Uno, Abbott) and orally given steroid-prednisone in one group (A+S) 56 patients. Second group of 60 patients were cured only with antibiotics (A). We compare effects of this therapy. There were 50% totally cured patients in the first group (A+S) and 46.6% cured in the second group. Percentage totally cured patients with (A+S) is 3.4% better that cured only with antibiotics in the same time. It is statistically important. We present benefits for patients who were operated in the next step. Post therapy with the use of antibiotics and steroids there were less bleeding from the mucosal membrane, and there was no edema. It is a good method of therapy if patients have no contraindications.

[Giant osteoma of the ethmoid and frontal sinuses].

The authors present a case of a huge osteoma of the ethmoid and frontal sinuses. An operative technique enabling radical removal without fragmentation of the tumor with preservation of the bony margins of the fronto-orbital region was presented.

[Is syndecan-1 an independent prognostic factor in patients with laryngeal carcinoma?].

Syndecan-1 is a member of the syndecan family of cell membrane heparan sulphate proteoglicans. The aim of this study was the evaluation of prognostic value of syndecan-1 expression in laryngeal cancer. The findings were correlated with the clinico-pathological parameters of the tumours, as well as with patient survival rate. Paraffin-embedded samples from 99 patients with laryngeal cancer selected from the files of the ENT-Dept. of Medical Academy in Lublin were immunostained with anti-syndecan-1 monoclonal antibody. The patients' mean age was 57 years and the over 5-year survival rate was 53.2%. Syndecan-1 immunoreactivity was observed in 99 (100%) of carcinomas. In our study, a statisti- cally significant correlation between syndecan-1 expression and patient survival rate was observed (chi2 = 9631; p = 0.008) as well as between syndecan-1 expression and various clinical stages of disease (chi2 = 6771; p = 0.034). The significant difference in the presence of syndecan-1 expression among the patients with various stage of histological differentiation of carcinoma (chi2 = 14.9; p = 0.001), and among the patients with present and absent metastatic changes in regional lymph nodes (chi2 = 16.698; p = 0.001) was observed. In a Coxs multivariate analysis syndecan-1 had an independent prognostic value (p = 0.014). Our results indicate that syndecan-1 could be used as a prognostic marker in laryngeal cancer.

Syndecan-1 expression in laryngeal cancer.

Syndecan-1 is a member of the syndecan family of cell surface heparan sulphate proteoglycans. The aim of this study was the evaluation of syndecan-1 expression in laryngeal cancer. The findings were correlated both with the clinico-pathological parameters of the tumours and with patient survival. Paraffin-embedded samples from 48 patients with laryngeal cancer selected from the files of the ENT Department of the Medical Academy in Lublin were immunostained with anti-syndecan-1 monoclonal antibody. The patients' mean age was 56 years, and 69% survived for over 3 years. Syndecan-1 immunoreactivity was observed in 48 (100%) of carcinomas. In our study, statistically significant correlations were observed both between syndecan-1 expression and patient survival (Chi-square = 4.364; P<0.05) and between syndecan-1 expression and clinical stage of disease (Chi-square = 4.363; P<0.05). Significant differences in syndecan-1 expression were also observed with various stages of histological differentiation of the carcinomas (Chi-square = 6.588; P<0.05), and also according to the presence or absence of metastatic changes in the regional lymph nodes (Chi-square = 6.289; P<0.05). Our results indicate that syndecan-1 could be used as a prognostic marker in laryngeal cancer.

Labyrinthitis in chronic otitis media.

Labyrinthitis is the most frequent complication of chronic otitis media (COM). Retrospective analysis of 1,210 patients operated due to COM was carried out. Circumscribed labyrinthitis was found in 17.2% and deafness in 1.2% of patients. To evaluate the effect of labyrinthitis on bone conduction (BC) we measured BC threshold in a group of 140 patients with unilateral COM without labyrinthitis and in a group of 42 patients with unilateral COM with labyrinthitis. BC threshold of the healthy ear was subtracted from the BC threshold of the affected ear in the same patient to eliminate presbyacusis. There was no significant difference in bone conduction threshold between the patients with circumscribed labyrinthitis and patients with COM without labyrinthitis. The incidence of labyrinthitis was higher in patients with cholesteatoma than in patients without cholesteatoma. Management of labyrinthine fistula is presented.
