The study results show that the levels of total pepsin and bile acids in saliva are significantly higher in patients with LPR than in the controls, thus suggesting this as a useful tool in the diagnosis of LPR and particularly biliary LPR.

BackgroundGastroesophageal reflux is suspected to be an etiological factor in laryngeal and pharyngeal cancer. The aim of this study was to establish, using a non-invasive method, whether laryngopharyngeal reflux (LPR) appears more often in patients with early laryngeal cancer than in a control group.Patients and methodsWe compared the pH, the level of bile acids, the total pepsin and the pepsin enzymatic activity in saliva in a group of 30 patients with T1 laryngeal carcinoma and a group of 34 healthy volunteers.ResultsThe groups differed significantly in terms of levels of total pepsin and bile acids in the saliva sample. Higher levels of total pepsin and bile acids were detected in the group of cancer patients. No significant impact of other known factors influencing laryngeal mucosa (e.g. smoking, alcohol consumption, and the presence of irritating substances in the workplace) on the results of saliva analysis was found.ConclusionsA higher level of typical components of LPR in the saliva of patients with early laryngeal cancer than in the controls suggests the possibility that LPR, especially biliary reflux, has a role in the development of laryngeal carcinoma.

Anogenital warts and laryngeal papillomas are two most important benign tumors etiologically linked with HPV. In the study, which included both the largest number of laryngeal papilloma tissue specimens (152 specimens from 152 patients) to date and the largest number of prospectively collected and histologically confirmed tissue specimens of anogenital warts obtained from both genders (422 specimens from 315 patients), HPV DNA was detected in 413/422 (97.9%) of anogenital warts and 139/152 (91.4%) of laryngeal papillomas. HPV‐6 and/or HPV‐11 were detected in 291/315 (92.4%) patients with anogenital warts and in 138/152 (90.8%) patients with laryngeal papillomas, indicating that the great majority of both tumors could be prevented with prophylactic quadrivalent vaccine. The HPV‐6 gender‐specific distribution in both anogenital warts and laryngeal papillomas was not statistically significant. In contrast, HPV‐11 was found almost three times more often in males than in females with anogenital warts (16.5% vs. 6.3%; P = 0.008), with a gender neutral HPV‐11 type distribution in laryngeal papillomas. The overall HPV DNA prevalence in anogenital warts was significantly different from that in laryngeal papillomas (97.1% vs. 91.4%; P = 0.01). In the first comparison of the HPV‐6/HPV‐11 type‐specific distribution between patients suffering from anogenital warts and laryngeal papillomas with the same geographic and ethnic background, a significant imbalance in tumor‐specific distribution of HPV‐6 and HPV‐11 was identified: HPV‐6 was statistically more often present in anogenital warts than in laryngeal papillomas (79.0% vs. 59.2%; P = 0.000013), whereas HPV‐11 was statistically more frequent in laryngeal papillomas than in anogenital warts (28.9% vs. 12.4%; P = 0.00003).

Background Dysphagia is a common consequence of treatment for head and neck cancer (HNC). The purpose of the study was to evaluate the prevalence of dysphagia in a group of patients treated for HNC in Slovenia, and to identify factors contributing to the development of dysphagia. Patients and methods One-hundred-nine consecutive patients treated for HNC at two tertiary centers were recruited during their follow-up visits. They fulfilled EORTC QLQ-H&N35 and “Swallowing Disorders after Head and Neck Cancer Treatment questionnaire” questionnaires. Patients with dysphagia were compared to those without it. Results Problems with swallowing were identified in 41.3% of the patients. Dysphagia affected their social life (in 75.6%), especially eating in public (in 80%). Dysphagia was found the most often in the patients with oral cavity and/or oropharyngeal cancer (in 57.6%) and in those treated less than 2 years ago (p = 0.014). In univariate analysis, a significant relationship was observed between dysphagia prevalence and some of the consequences of anti-cancer treatment (impaired mouth opening, sticky saliva, loss of smell, impaired taste, oral and throat pain, persistent cough, and hoarseness), radiotherapy (p = 0.003), and symptoms of gastroesophageal reflux (p = 0.027). After multiple regression modelling only persistent cough remained. Conclusions In order to improve swallowing abilities and, consequently, quality of life of the patients with HNC a systematic rehabilitation of swallowing should be organized. A special emphasis should be given to gastroesophageal reflux treatment before, during and after therapy for HNC

The prevalence of voice disorders in Catholic priests in Slovenia is high. Respiratory-tract infection is the most common cause of their voice problems. Allergies, frequent throat clearing, not receiving instruction on correct vocal use and vocal hygiene, and a history of voice problems during training were stated as risk factors for voice disorders. In order to decrease the prevalence of voice disorders in priests and in other occupations with a large vocal load, we suggest that an ENT examination before the start of training and the inclusion of information on correct use of the voice and on diseases influencing voice quality should be included as a standard part of the educational process.

The purpose of this study was to compare the prevalence of ear, nose and particularly voice problems in groups of children with cleft palate (CP) and with unilateral cleft lip, alveolus and palate (UCLP). On the basis of history, regular otorhinolaryngological examinations and hearing tests, the prevalence of different pathologies was assessed in 80 CP children (35 boys and 45 girls) and 73 UCLP children (47 boys and 26 girls). Ear pathology was reported in 53.8 per cent of CP children and in 58.9 per cent of UCLP children. Nasal breathing was impaired in 14 CP (17.5 per cent) and 36 UCLP (49.3 per cent) children. Dysphonia was detected in 12.5 per cent of CP and 12.3 per cent of UCLP children. In 9.2 per cent of all cleft children, functional voice disorder caused a hoarse voice. Two-thirds of cleft children with functional dysphonia had protracted hearing loss. Therefore, ENT specialists must take an active role early in the treatment of children with clefts.
