Abstract

Evaluating the H(x, s; pp) scaling function of elastic proton-proton (pp) collisions from recent TOTEM data at sqrt(s) = 8 TeV and comparing it with the same function of elastic proton-antiproton (pp-) data of the D0 collaboration at sqrt(s) = 1.96 TeV, we find, from this comparison alone, an at least 3.79 sigma {\signal} of Odderon exchange. If we combine this model independently obtained result with that of a similar analysis but using TOTEM elastic pp scattering data at sqrt(s) = 7 TeV, which resulted in an at least 6.26 {\sigma} signal, the combined significance of Odderon exchange increases to at least 7.08 {\sigma}, model independently. Further combinations of various datasets in the TeV energy range are detailed in the manuscript, Comment: 18 pages, 6 figures, presented at 52nd International Symposium on Multiparticle Dynamics (ISMD 2023), Aug 21 - 26, 2023, MATE-KRC, Gy\"ongy\"os, Hungary

3. Simple L\'evy-$\alpha$ stable model analysis of elastic $pp$ and $p\bar p$ low-$|t|$ data from SPS to LHC energies

Abstract

A simple L\'evy-$\alpha$ stable (SL) model is used to describe the data on elastic $pp$ and $p\bar p$ scattering at low-$|t|$ from SPS energies up to LHC energies. The SL model is demonstrated to describe the data with a strong non-exponential feature in a statistically acceptable manner. The energy dependence of the parameters of the model is determined and analyzed. The L\'evy $\alpha$ parameter of the model has an energy-independent value of 1.959 $\pm$ 0.002 following from the strong non-exponential behavior of the data. We strengthen the conclusion that the discrepancy between TOTEM and ATLAS elastic $pp$ differential cross section measurements arises only in the normalization and not in the shape of the distribution of the data as a function of $t$. We find that the slope parameter has different values for $pp$ and $p\bar p$ elastic scattering at LHC energies. This may be the effect of the odderon exchange or the jump in the energy dependence of the slope parameter in the energy interval 3 GeV $\lesssim \sqrt s \lesssim$ 4 GeV., Comment: 30 pages, 5 figures, 1 table; presented at ISMD 2023; an extended introduction and an appendix are added

4. L\'evy $\alpha$-stable model for the non-exponential low-$|t|$ proton-proton differential cross section

Abstract

It is known that the Real Extended Bialas-Bzdak (ReBB) model describes the proton-proton ($pp$) and proton-antiproton ($p\bar p$) differential cross-section data in a statistically non-excludible way,\linebreak i.e., with a confidence level greater than or equal to 0.1\% in the center of mass energy range \linebreak 546 GeV $\leq\sqrt{s}\leq$ 8 TeV and in the squared four-momentum transfer range 0.37 GeV$^2$ $\leq -t\leq$ 1.2 GeV$^2$. Considering, instead of Gaussian, a more general L\'evy $\alpha$-stable shape for the parton distributions of the constituent quark and diquark inside the proton and for the relative separation between them, a generalized description of data is obtained, where the ReBB model corresponds to the $\alpha =$ 2 special case. Extending the model to $\alpha <$ 2, we conjecture that the validity of the model can be extended to a wider kinematic range, in particular, to lower values of the four-momentum transfer $-t$. We present the formal L\'evy $\alpha$-stable generalization of the Bialas-Bzdak model and show that a simplified version of this model can be successfully fitted, with $\alpha<$ 2, to the non-exponential, low $-t$ differential cross-section data of elastic proton-proton scattering at $\sqrt{s} =$ 8 TeV., Comment: 13 pages, 2 figures

Physics, QC1-999
Abstract

We investigate the scaling properties of elastic scattering data at ISR and LHC energies, and find that the significance of an Odderon observation is larger than the discovery threshold of 5σ. As an unexpected by-product of these investigations, for certain experimentally relevant cases, we also conjecture the possibility of proton holography with the help of elastic proton-proton scattering.

Abstract

We complete the model-independent analysis of the scaling properties of the differential cross section of elastic proton-proton cross sections, including new TOTEM data published in 2022 at $\sqrt{s} = 8$ TeV. We separate the signal and the background region with a new gating method. In the signal region, we find that the statistical significance of Odderon exchange from the combined 7.0 and 8.0 TeV $pp$ data of TOTEM and the 1.96 TeV $p\bar{p}$ data of D0 is at least 7.32$\sigma$. In the background region, the scaling functions of elastic proton-proton data at 7 and 8 TeV and that of elastic proton-antiproton scattering data at 1.96 TeV agree with a statistical significance not larger than 1.93$\sigma$., Comment: 6 pages, 1 figures, accepted for publication in Acta Phys.

Abstract

The Real Extended Bialas-Bzdak (ReBB) model study is extended to the 8 TeV $pp$ TOTEM elastic differential cross section data. The analysis shows that the ReBB model describes the $pp$ and $p\bar{p}$ differential cross section data in the limited $0.37 \leq -t \leq 1.2$ GeV$^2$ and $1.96 \leq \sqrt{s} \leq 8$ TeV kinematic region, in a statistically acceptable manner. In this kinematic region a greater than 30 $\sigma$ model-dependent Odderon signal is observed by comparing the $pp$ and ReBB extrapolated $p\bar{p}$ differential cross sections. Thus, in practical terms, within the framework of the ReBB model, Odderon exchange is not a probability, but a certainty., Comment: 7 pages, 3 figures, 5 tables, presented by I.

Abstract

The Real Extended Bialas-Bzdak (ReBB) model is shown here to describe, in the $0.37 \le -t \le 1.2$ GeV$^2$ region, the proton-proton elastic differential cross section data published by the TOTEM Collaboration at LHC at $\sqrt{s} = 8 $ TeV center of mass energy. In this kinematic range, corresponding to the diffractive minimum-maximum region, a model-dependent Odderon signal higher than 18 $\sigma$ is obtained by comparing the ReBB model prediction for the $p\bar{p}$ elastic differential cross section to this TOTEM measured $pp$ elastic differential cross section data at 8 TeV. However, when combining this signal with the Odderon signals from the ReBB model in the $0.37 \leq -t \leq 1.2$ GeV$^2$ four-momentum-transfer range at $\sqrt{s} = $ 1.96, 2.76 and 7 TeV, it turns out that the combined significance is dominated not by the new 8 TeV but by that of earlier 7 TeV TOTEM data, that carry an even larger Odderon effect. Thus, in any practical terms, within the framework of the ReBB model, the Odderon signal in the limited $0.37 \leq -t \leq 1.2$ GeV$^2$ and $1.96 \leq \sqrt{s} \leq 8$ TeV kinematic region is not a probability, but a certainty. We show also that the $H(x)$ scaling version of the ReBB model works reasonably well at 8 TeV in the $0.37 \le -t \le 0.97$ GeV$^2$ region., Comment: 8 pages, 4 figures, 2 tables; typos corrected

Abstract

We describe an analysis comparing the $p\bar{p}$ elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in $pp$ collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections extrapolated to a center-of-mass energy of $\sqrt{s} =$ 1.96 TeV are compared with the D0 measurement in the region of the diffractive minimum and the second maximum of the $pp$ cross section. The two data sets disagree at the 3.4$\sigma$ level and thus provide evidence for the $t$-channel exchange of a colorless, $C$-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same $C$-odd exchange based on the total cross section and the ratio of the real to imaginary parts of the forward elastic scattering amplitude in $pp$ scattering. The combined significance of these results is larger than 5$\sigma$ and is interpreted as the first observation of the exchange of a colorless, $C$-odd gluonic compound., Comment: D0 and TOTEM Collaborations

10. Observation of Odderon Effects at LHC energies -- A Real Extended Bialas-Bzdak Model Study

Abstract

The unitarily extended Bialas-Bzdak model of elastic proton-proton scattering is applied, without modifications, to describe the differential cross-section of elastic proton-antiproton collisions in the TeV energy range, and to extrapolate these differential cross-sections to LHC energies. In this model-dependent study we find that the differential cross-sections of elastic proton-proton collision data at 2.76 and 7 TeV energies differ significantly from the differential cross-section of elastic proton-antiproton collisions extrapolated to these energies. The elastic proton-proton differential cross-sections, extrapolated to 1.96 TeV energy with the help of this extended Bialas-Bzdak model do not differ significantly from that of elastic proton-antiproton collisions, within the theoretical errors of the extrapolation. Taken together these results provide a model-dependent, but statistically significant evidence for a crossing-odd component of the elastic scattering amplitude at the at least 7.08 sigma level. From the reconstructed Odderon and Pomeron amplitudes, we determine the $\sqrt{s}$ dependence of the corresponding total and differential cross-sections., Comment: Final version, typos fixed, accepted for a publication in EPJ C, including 3 tables, 32 figures, 61 pages. Model dependent Odderon significance stands at 7.08 sigma. Appendix C and D added to discuss the s-dependent Pomeron and Odderon amplitudes and cross-sections and to cross-check possible non-linear evolution of the model parameters at ISR energies

Abstract

We study the scaling properties of the differential cross section of elastic proton-proton ($pp$) and proton-antiproton ($p\bar p$) collisions at high energies. We introduce a new scaling function, that scales -- within the experimental errors -- all the ISR data on elastic $pp$ scattering from $\sqrt{s} = 23.5$ to $62.5$ GeV to the same universal curve. We explore the scaling properties of the differential cross-sections of the elastic $pp$ and $p\bar p$ collisions in a limited TeV energy range. Rescaling the TOTEM $pp$ data from $\sqrt{s} = 7$ TeV to $2.76$ and $1.96$ TeV, and comparing it to D0 $p\bar p$ data at $1.96$ TeV, our results provide an evidence for a $t$-channel Odderon exchange at TeV energies, with a significance of at least 6.26$\sigma$. We complete this work with a model-dependent evaluation of the domain of validity of the new scaling and its violations. We find that the $H(x)$ scaling is valid, model dependently, within $200$ GeV $ \leq \sqrt{s} \leq$ $ 8$ TeV, with a $-t$ range gradually narrowing with decreasing colliding energies., Comment: Accepted in EPJ C, with typos fixed, reorganized institutions updated, Appendix A, B, C, D, E added, 60 pages, 29 figures, 13 tables, Odderon significance: 6.26 sigma, conclusions unchanged

19. The ReBB model and its $H(x)$ scaling version at 8 TeV

Abstract

The Real Extended Bialas-Bzdak (ReBB) model is shown here to describe, in the 0.37 $\le -t \le$ 1.2 GeV$^2$ region, the proton-proton elastic differential cross section data published by the TOTEM Collaboration at LHC at $\sqrt{s} =$ 8 TeV colliding energy. In this kinematic range, corresponding to the diffractive minimum-maximum region, a model-dependent Odderon signal higher than 18 $\sigma$ is obtained by comparing the ReBB model prediction for the $p\bar{p}$ elastic differential cross section to this TOTEM measured $pp$ elastic differential cross section data at 8 TeV. However, when combining this signal with the Odderon signals from the ReBB model in the 0.37 $\leq -t \leq$ 1.2 GeV$^2$ four-momentum-transfer range at $\sqrt{s} = $ 1.96, 2.76 and 7 TeV, it turns out that the combined significance is dominated not by the new 8 TeV but by that of earlier 7 TeV TOTEM data, that carry an even larger Odderon effect. Thus, in any practical terms, within the framework of the ReBB model, the Odderon signal in the limited 0.37 $\leq -t \leq$ 1.2 GeV$^2$ and 1.96 $\leq \sqrt{s} \leq$ 8 TeV kinematic region is not a probability, but a certainty. We show also that the $H(x)$ version of the ReBB model works reasonably well at 8 TeV in the 0.37 $\le -t \le$ 0.97 GeV$^2$ region., Comment: 8 pages, 3 figures, 2 tables

Abstract

International audience; We describe an analysis comparing the pp¯ elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections, extrapolated to a center-of-mass energy of s=1.96 TeV, are compared with the D0 measurement in the region of the diffractive minimum and the second maximum of the pp cross section. The two data sets disagree at the 3.4σ level and thus provide evidence for the t-channel exchange of a colorless, C-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same C-odd exchange based on the total cross section and the ratio of the real to imaginary parts of the forward elastic strong interaction scattering amplitude in pp scattering for which the significance is between 3.4σ and 4.6σ. The combined significance is larger than 5σ and is interpreted as the first observation of the exchange of a colorless, C-odd gluonic compound.

Abstract

Made available in DSpace on 2022-04-28T19:42:50Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-08-06 We describe an analysis comparing the pp¯ elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections, extrapolated to a center-of-mass energy of s=1.96 TeV, are compared with the D0 measurement in the region of the diffractive minimum and the second maximum of the pp cross section. The two data sets disagree at the 3.4σ level and thus provide evidence for the t-channel exchange of a colorless, C-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same C-odd exchange based on the total cross section and the ratio of the real to imaginary parts of the forward elastic strong interaction scattering amplitude in pp scattering for which the significance is between 3.4σ and 4.6σ. The combined significance is larger than 5σ and is interpreted as the first observation of the exchange of a colorless, C-odd gluonic compound.

Abstract

We describe a quantitative analysis comparing the p anti-p elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a mainly model-independent approach. The TOTEM cross sections extrapolated to a center-of-mass energy of sqrt(s) = 1.96 TeV are compared with the D0 measurement in the region of the diffractive minimum and the second maximum of the pp cross section. The two data sets disagree at the 3.4σ level and thus provide evidence for the t-channel exchange of a colorless, C-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same C-odd exchange based on the total cross section and the ratio of the real to imaginary parts of the forward elastic scattering amplitude in pp scattering. The combined significance is larger than 5σ.

Abstract

We provide a statistically significant observation of the elusive Odderon exchange, based on novel and model-independent analysis of the scaling properties of the differential cross sections of elastic $pp$ and $p\bar p$ scattering in the TeV energy range. We report the statistical significance of the observed Odderon signal at the level of 6.26$\sigma$., Comment: 11 pages, 2 figures, theoretical results added to Figs. 1 and 2, discussion improved, connection to elastic scattering pp measurements at RHIC added, conclusions and Odderon significance unchanged

Abstract

We describe an analysis comparing the $p\bar{p}$ elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in $pp$ collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections extrapolated to a center-of-mass energy of $\sqrt{s} =$ 1.96 TeV are compared with the D0 measurement in the region of the diffractive minimum and the second maximum of the $pp$ cross section. The two data sets disagree at the 3.4$\sigma$ level and thus provide evidence for the $t$-channel exchange of a colorless, $C$-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same $C$-odd exchange based on the total cross section and the ratio of the real to imaginary parts of the forward elastic scattering amplitude in $pp$ scattering. The combined significance of these results is larger than 5$\sigma$ and is interpreted as the first observation of the exchange of a colorless, $C$-odd gluonic compound., Comment: D0 and TOTEM Collaborations

Abstract

The central exclusive diffractive (CED) production of meson resonances potentially is a factory producing new particles, in particular, a glueball. The produced resonances lie on trajectories with vacuum quantum numbers, essentially on the pomeron trajectory. A tower of resonance recurrences, the production cross-section, and the resonances widths are predicted. A new feature is the form of a non-linear pomeron trajectory, producing resonances (glueballs) with increasing widths. At LHC energies, in the nearly forward direction, the t-channel both in elastic, single, or double diffraction dissociations, as well as in CED, is dominated by the pomeron exchange (the role of secondary trajectories is negligible, however a small contribution from the odderon may be present)., Центральне ексклюзивне дифракцiйне (ЦЕД) народження мезонних резонансiв потенцiйно може бути фабрикою нових частинок, зокрема глюболiв. Отриманi резонанси лягають на траєкторiї з вакуумними квантовими числами, переважно на траєкторiю померона. Отримано ширини резонансiв та їхнiй поперечний перерiз. Новою особливiстю є використання нелiнiйної траєкторiї для померона, що продукує резонанси (глюболи) зi зростаючою шириною. При енергiях ВАК, у майже прямому напрямку в t-каналi як при пружних – одинарної чи подвiйної дифракцiйної дисоцiацiї, так i в ЦЕД домiнує обмiн померонами (вплив вторинних траєкторiй нехтовний, хоча можливе врахування невеликого внеску оддерона).

Abstract

The authors investigated the usefulness of the interphase cytogenetic approach to reveal numerical chromosomal abnormalities. Experiments performed on normal human cells using chromosome specific (peri)centromeric probes indicated that disomy was recognized in a range of 89.1 +/- 5.4%-96.8 +/- 0.4% for the somatic chromosomes and in 98.1 +/- 0.8% for the sex chromosomes. Using positivity threshold of mean percentage of the fals monosomy and trisomy + 2 SD, chromosome loss or gain for the somatic chromosomes could be revealed beyond clonal ratio of 3.6-13.2% and 1.1-6.8%, respectively. The same value for the sex chromosomes was 3.2% and 0%, respectively. Eleven pediatric acute lymphoid leukaemia were investigated for chromosomal aneuploidy by interphase cytogenetics using chromosome specific (peri)centromeric probes for all the somatic and sex chromosomes. Results were compared with metaphase cytogenetic and flow cytometry derived gross DNA aneuploidy data. In 5 cases the leukaemic cells proved to be diploid with all three methods at both gross DNA and chromosome levels. Interphase cytogenetics revealed chromosome loss or gain in all the remaining 6 cases, however, metaphase analysis indicated numerical aberration in only 2 patients. In one of them only the increased chromosome number could have been detected without identifying the chromosomes involved and in the other one the two methods indicated trisomy for not the same chromosome. Flow cytometry data showed aneuploidy in 3 out of the 6 aneuploid leukaemia. The results imply that interphase cytogenetics might be more accurate as compared with flow cytometry and metaphase analysis to reveale aneuploidy.

Abstract

We analyse the recently discovered phenomena in elastic protonproton scattering at the LHC: the low-|t| “break” (departure from the exponential behaviour of the diffraction cone), the accelerating rise with energy of the forward slope B(s), the absence of secondary dips and bumps on the cone and the role of the odderon in the forward phase of the amplitude, ρ(13 TeV) = 0:09 ± 0:01, especially its contribution at the dip region, measured recently by TOTEM. The dip at 13 TeV seems to become more shallow with respect to lower energies, and we attribute this important new phenomena to the odderon contribution. These findings call for a revision of the standeard Regge-pole theory.

Abstract

The authors report long-lasting airplane headache in a patient with non-allergic, chronic rhinosinusitis. Association of mucosal inflammation with compromised sinonasal ventilation and sinus barotrauma created a base for not only the pain but also for the prolongation of symptoms. Effective therapy with antihistamine and nasal decongestant supports the theory that sinonasal barotrauma plays a triggering role in the pathophysiology of airplane headache. [ABSTRACT FROM AUTHOR]

Abstract

Background/objectives: The goal of this investigation was to compare the time to biopsy (TBI) and time to treatment (TTI) for head and neck squamous cell carcinoma (HNSCC) patients before and during the COVID-19 pandemic and to examine the effect of demographic and clinical characteristics on these intervals., Methods: Our retrospective study at a large regional Hungarian cancer center analyzed data from patients aged 18 or older diagnosed with HNSCC between 1 January 2017 and 15 March 2020 (pre-COVID-19 period) and 16 March 2020 to 13 May 2021 (COVID-19 period). We calculated the time from initial physician contact to biopsy (TBI) and from biopsy to treatment initiation (TTI) and performed descriptive and exploratory statistical analyses., Results: The median TBI decreased significantly (6 vs. 3 days; p = 0.008), while the median TTI was not affected significantly (28 vs. 29 days; p = 0.972) pre-pandemic and during the pandemic, respectively. Residence in a village was linked to a significant reduction in median TBI during the pandemic ( p = 0.000), coinciding with a higher proportion of rural patients diagnosed with oral cavity/oropharyngeal cancers during the pandemic (50.3% pre-pandemic vs. 67.4% during pandemic, p = 0.044). Median TTI decreased significantly during the pandemic for patients with laryngeal tumors (27.5 vs. 18.5 days; p = 0.012)., Conclusions: Our study, one of a few from this region, provides insights into HNSCC patient waiting times. Improvement in TBI likely resulted from the availability of telemedicine, reduced diagnostic demands from non-cancer patients, and an increased incidence of oral cavity/oropharyngeal cancer among rural patients.

Abstract

Recently, organ preservation has gained importance for head and neck malignancies. The negative consequences of the therapies can be reduced without compromising the survival and the quality of life. Accordingly, transoral robotic surgery (TORS) is gaining ground internationally. We have been performing TORS procedures at the University of Pécs since January 2023. We operated on 27 patients until July 2024, including fifteen p16-positive tumors. Neck dissections were performed in 19 cases. The use of TORS is helpful in oropharyngeal cases, where inaccessible structures can be reached minimally invasively, compared to other transoral approaches. This is important for young patients with human papillomavirus-associated tumors, which have a better prognosis and longer life expectancy. TORS also has advantages over the previously used approaches for cancer of unknown primary (CUP). Compared to the standardly used FDG-PET/CT and "blindly" taken biopsies, TORS offers a higher detection rate of the primary tumor, by performing tonsillectomy and complete mucosectomy of the tongue base.

Abstract

The aim of our study was to compare the characteristics and time to initial physician contact in patients with head and neck squamous cell carcinoma (HNSCC) before and during the COVID-19 pandemic at a large Hungarian cancer center. This was a retrospective study of patients 18 years or older presenting at the regional cancer center of Pécs Clinical Center with HNSCC between 1 January 2017, and 15 March 2020 (the pre-COVID-19 period) and between 16 March 2020, and 13 May 2021 (the COVID-19 period). Demographic and clinical data were collected, and the time between initial symptom onset and initial physician contact (TTP) was determined. Descriptive and exploratory statistical analyses were performed. On average, the number of patients diagnosed with HNSCC per month during the pandemic decreased by 12.4% compared with the pre-COVID-19 period. There was a significant increase in stage I and stage II cancers (from 15.9% to 20.3% and from 12.2% to 13.8%, respectively; p < 0.001); a decrease in stage III and IVa,c cancers; and a significant increase in stage IVb cancers (from 6% to 19.9%; p < 0.001) during the pandemic. The median TTP increased during the pandemic from 43 to 61 days (p = 0.032). To our knowledge, this is the first study investigating the effect of COVID-19 on patients with HNSCC in the Central-Eastern European region. We found a bidirectional shift in cancer stages and increased TTP during the pandemic. Our findings highlight the necessity for more nuanced analyses of the effects of COVID-19.

Abstract

The purpose of this study was to examine the quality of life (QoL) and hearing thresholds of patients who underwent 2 types of stapes surgery. A retrospective cohort study was performed comparing stapedotomy with NiTiBOND prostheses (n=20) and stapedectomy with autogenous cortical bone columella (n=20), applying the Glasgow Benefit Inventory (GBI) and the Hearing Handicap Inventory for Adults outcome measures with hearing thresholds. Univariate comparative statistical methods were applied. The stapedotomy cohort had significantly better values of Social Support Score of the GBI as compared to the stapedectomy cohort (P=.016). No statistically significant difference was detected between the groups in the pre- and postoperative audiological results and the further QoL measures. Apart from the excellent postoperative audiological results of the different types of stapes surgeries, stapedotomy with NiTiBOND prostheses seems to be superior as regards QoL over stapedectomy applying autogenous cortical bone columella.

Abstract

Purpose: Single-sided deaf patients following cochlear implantation often compare the sound quality of their implanted ear with normal hearing. The interaural differences can result in dissatisfaction with speech comprehension and reduced time of usage of the speech processor; hence, prolonging auditory adaptation time. The proposed calibration method presented in this study demonstrates how the frequency distribution of the cochlear implant can be set to adequately approximate the pitch perception of the contralateral normal hearing ear towards improving speech intelligibility in a noisy environment., Methods: In 12 postlingual single-sided deaf patients, subjective interaural pitch-matching was carried out to determine new central frequencies for the reallocation of the frequency bands of their speech processor (CP910, CP950 or CP1000, Cochlear, Australia). The patients were asked to compare the pitch of the tones presented to their normal hearing ear to the pitch of individual channels of their cochlear implant (CI522 or CI622, Cochlear, Australia). A third-degree polynomial curve was fit to the acquired matching frequencies to create the new frequency allocation table. Audiological measurements (free-field aided thresholds, speech reception thresholds, and monosyllabic word recognition score) in noise, together with a Speech, Spatial and Qualities of Hearing Scale (SSQ12) questionnaire (short version of the original SSQ) results were evaluated prior to the pitch-matching procedure, and again, 2 weeks later., Results: The free-field aided thresholds of the patients showed no greater shift than ± 5 dB following the procedure; however, their monosyllabic word recognition score in noise improved significantly (mean - 9.58%, SD 4.98%, matched pairs t test comparison: p < 0.001). The results of the SSQ12 questionnaire also showed significant improvement in speech intelligibility, sound localization, and sound quality (mean 0.96 points, SD 0.45 points, matched pairs t test comparison: p < 0.001)., Conclusions: Matching the pitch perception of the implanted cochlea with the sensation of the normal hearing contralateral ear, resulted in significant changes in the quality of hearing in patients with single-sided deafness. It is plausible the procedure can usher positive results in bimodal patients or following sequential bilateral cochlear implantation., (© 2023. The Author(s).)

Abstract

Purpose: Endoscopic type I tympanoplasty was originally introduced in the 1990s and the extensive spread of this practice can be easily observed. The conventional technique performed involves the repair of a tympanic membrane perforation and is defined as microscopic type I tympanoplasty. The aim of this study is the comparison of quality-of-life (QoL) outcomes with endoscopic to that with microscopic type I tympanoplasty., Methods: All patients, or in the case of children with the aid of a parent, were asked to complete a novel QoL questionnaire drafted by our study group. The analysis was performed with descriptive statistics-mean, SD and relative frequency-and with a mixed model (generalized least squares fit). A two-sided p value of < 0.05 was regarded as statistically significant., Results: A total of 83 patients completed the questionnaire, 38 in the endoscopic group and 45 in the microscopic group. Every question represented a different. A statistically significant result was found in favor of the endoscopic approach regarding average hospitalization rate (p = 0.003) and cosmetic outcomes (p = 0.015). No statistically significant difference was otherwise observed between the groups., Conclusions: Based on our prospective cohort study, the QoL outcomes of endoscopic type I tympanoplasty in terms of postoperative pain, headache, nausea, vomiting, dizziness, taste disorder and hearing were comparable to the microscopic type I tympanoplasty. In regard to cosmetics, an increase in desirable results was achieved in the endoscopic group, particularly the average hospitalization rate proved to be statistically significantly lower than in the microscopic group., (© 2023.

Abstract

Branchial cleft cyst is the most common birth defect involving the neck. Malignant transformation is known, however, differentiating from a neck metastasis of a squamous cell carcinoma of unknown primary is challenging. Even though there are strict criterias, the diagnosis of this entity remains controversial. We present the case of a 69-year-old woman, who presented with a swelling under the left side of the mandible. After diagnostic workup, fine-needle aspiration biopsy raised the suspicion of a cystic squamous cell carcinoma metastasis, therefore we performed panendoscopy and modified radical neck dissection. The pathological examination confirmed branchial cleft cyst carcinoma. After surgery, the patient received adjuvant radiation and chemotherapy. During the case workup, we present the difficulties of the diagnostic process, differential diagnostic problems, and the review of the international literature. In the case of a solitary, cystic mass on the neck without a primary tumor, we should consider the possibility of a branchiogenic carcinoma. Orv Hetil. 2023; 164(10): 388-392.

Abstract

Background and Objectives: Chronic suppurative otitis media (CSOM) with or without cholesteatoma is a frequent chronic inflammatory condition in children, which may lead to severe hearing loss that affects speech development. Treatment of recurrent CSOM associated with unserviceable hearing requires a specialized approach with regard to disease eradication and hearing rehabilitation. In this study, we investigated the advantages of subtotal petrosectomy (SP) combined with cochlear implantation (CI) in children with CSOM associated with unserviceable hearing and describe our experience with regard to the efficacy of this method, together with a literature review., Subjects and Methods: SP with sequential or simultaneous CI was performed in three children (four ears), and postoperative audiometric data were recorded., Results: The study included two male and one female patient. Mean age at the time of SP was 10.75 years (7-13 years). Sequential implantation was performed in three ears. Facial nerve palsy occurred after SP in one patient. The latest word recognition scores of Cases 1, 2, and 3 were 80% (at 60 dB), 75% (at 60 dB), and 70% (at 50 dB) and 90% (at 50 dB), respectively., Conclusions: SP with CI may be safe and reliable in children with CSOM associated with unserviceable hearing.
