RESUMEN
OBJECTIVE: Oropharyngeal/laryngeal carcinoma are common cancers of the upper aerodigestive system. Human papillomavirus (HPV) is described as the most frequent in the cancer of unknown primary. The presence of Helicobacter pylori (HP) in the oral cavity is discussed in some papers. THE AIM OF STUDY: To analyze the incidence of HPV and HP in oropharyngeal/laryngeal cancer persons versus persons with chronic tonsillar inflammation and healthy persons. METHODS: The samples were taken in three groups: (1) tissue of oropharynx/larynx cancer (103 specimens); (2) tissue of palatine tonsils (85 specimens); and (3) healthy control group (50 specimens). We analyzed the presence of HP (PCR) and HPV genomic DNA (Sacace HPV High-Risk Screen Real-TM Quant) in the samples. RESULTS: HP was detected in 86 samples (83.5%) and high-risk HPV in 62 samples (60.2%). We found a very high incidence of HP. In the cancer group, HP was detected in 82.5% cases and HPV positivity in 57.8%. In total, 7.2% of the cancer patients were negative for HP and HPV together. In turn, 53.6% of the cancer patients were positive for HP and HPV together. Four cases (4.2%) were positive for HPV only. VacA positivity was detected in 82 (79.6%) of the cancer cases and VacA negativity in 21 (20.4%) if the cancer cases. The incidence of HP in chronic inflammation (n = 85) was 65 cases (76.5%) and the incidence of HPV was 38 cases (44.7%). VacA positivity was detected in 59 (69.4%) of the chronic inflammation cases and VacA negativity was found in 26 (30.6%) of the chronic inflammation cases. Regarding the control group, we found HP positivity in 5 cases (11.1%) and HPV positivity in 19 cases (42.2%). There was VacA positivity in 6 cases (50.0%) of the control group. Statistically significantly lower prevalence of HP (p < 0.001) and HPV (p = 0.006) was found in the control group. CONCLUSIONS: We suggest that the palatine tonsils are colonized by HP. In our study, HP was present in oropharyngeal cancer in more cases in comparison with HPV infection. The presence of VacA from HP can have an influence on the human epithelial and immune cells' regulation ways. Our results do not support idea that the CagA-positive HP is a primary carcinogen in oropharyngeal area.

BACKGROUND: Acute acoustic trauma (AAT) ranks, among others, as one common cause of inner ear function impairment, especially in terms of military personnel, who are at an increased exposure to impulse noises from firearms. AIM OF THIS STUDY: 1. We wanted to demonstrate whether early treatment of AAT means a higher chance for the patient to improve hearing after trauma. 2. We find the answer to the question of whether hyperbaric oxygen therapy (HBO2) has a positive effect in the treatment of AAT. METHODS: We retrospectively analyzed data for the period 2004-2019 in patients with AAT. We evaluated the therapeutic success of corticosteroids and HBO2 in a cohort of patients with AAT n = 108 patients/n = 141 affected ears. RESULTS: Hearing improvement after treatment was recorded in a total of 111 ears (79%). In terms of the data analysis we were able to ascertain, utilizing success of treatment versus timing: within 24 h following the onset of therapy in 56 (40%) ears-54 (96%) ears had improved; within seven days following the onset the therapy was used in 55 (39%) ears-41 (74%) ears had improved; after seven days the therapy started in 30 (21%) ears-16 (53%) ears had improved. Parameter latency of the beginning of the treatment of AAT was statistically significant (p = 0.001 and 0.017, respectively). The success of the medical protocols was apparent in both groups-group I (treated without HBO2): n = 61 ears, of which 50 (82%) improved, group II (treated with HBO2): n = 73 ears, of which 56 (77%) improved. Group II shows improvement at most frequencies (500-2000 Hz). The most serious sensorineural hearing loss after AAT was at a frequency of 6000 Hz. CONCLUSION: Analysis of our data shows that there is a statistically significant higher rate of improvement if AAT treatment was initiated within the first seven days after acoustic trauma. Early treatment of AAT leads to better treatment success. HBO2 is considered a rescue therapy for the treatment of AAT. According to our recommendation, it is desirable to start corticosteroid therapy immediately after acoustic trauma. If hearing does not improve during the first seven days of corticosteroid therapy, then HBO2 treatment should be initiated.

Introduction: Total thyroidectomy (TT) is one of the most common surgical endocrine surgeries. Voice impairment after TT can occur not only in patients with recurrent laryngeal nerve (RLN) transient paralysis, but also in cases of normal vocal cord mobility. Aim: To compare voice limits using a speech range profile (SRP) in patients before and 14 days after TT and to investigate the influence of the early results of voice quality after TT on the personal lives of patients. We focused on the perception of voice change before and shortly after TT. Materials and methods: A retrospective study, in the period 2018-2020, included 65 patients aged 22-75 years. We compared two groups of patients: group I (n = 45) (without RLN paresis) and group II (n = 20) (with early transient postoperative RLN paresis). Patients underwent video flexible laryngocopy, SRP, and Voice Handicap Index-30 (VHI-30). Results: In group I, the mean values of Fmax (maximum frequency) and Imax (maximum intensity) decreased in women (both p = 0.001), and VHI-30 increased (p = 0.001). In group II after TT in women, the mean Fmax and Imax values decreased (p = 0.005 and p = 0.034), and the frequency range of the voice was reduced from 5 to 2 semitones. The dynamic range of the voice was reduced by 3.4 dB in women and 5.1 dB in men.VHI-30 increased (p = 0.001). Conclusion: The study documented a worsening of the mean values of SRP, VHI-30, and voice parameters of patients in group II. Voice disorders also occurred in group I without RLN paresis. Non-paretic causes can also contribute to voice damage after TT. SRP and VHI-30 are suitable tools for comparing voice status in two groups of patients, including those with dysphonia. Our data support the claim that the diagnosis of a thyroid cancer does not necessarily imply a higher postoperative risk of impaired voice quality for the patient.
