Patient reported voice handicap and auditory-perceptual voice assessment outcomes in patients with COVID-19.

PURPOSE: The purpose of this study is to compare patient-reported voice handicap and auditory-perceptual measures of voice between healthy individuals and COVID-19 patients, as well as to investigate the effect of clinical factors on voice quality. METHODS: COVID-19 patients (n = 138) and 90 healthy controls were included in the study. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) was used to grade voice samples based on overall severity, roughness, breathiness, strain, pitch, and loudness. The Voice Handicap Index-10 was completed by all participants (VHI-10). Physical (pVHI), emotional (eVHI) and functional (fVHI) subscores were calculated. Clinical data were collected (disease stage, CT grade, neutrophil/lymphocyte ratio, CRP, and symptoms). RESULTS: A statistically significant difference between patient and control groups in VHI-10 and CAPE-V scores was detected (p < 0.001). Except eVHI, total score and all subscale scores were higher in patients with COVID-19 as the pVHI was the most affected (η2 = 0.324) subscale. All scores of CAPE-V were significantly worse in patients with COVID-19 as highest impact of COVID-19 was on breathiness (η2 = 0.518). Pre-existing pulmonary comorbidity, dyspnoea and N/L was significantly associated with the VHI-10 overall score (ßpc = 4.27, ßdyspnoea = 5.69 and ßnl = 0.25). The overall severity of CAPE-V was significantly dependent on dyspnoea and pulmonary comorbidity (ßdyspnoea = 11.25, ßpc = 10.12). VHI ≥4 and CAPE-V overall severity ≥11 were good indicators of COVID-19 related dysphonia. CONCLUSIONS: COVID-19 causes patient-reported voice handicap and deteriorates auditory-perceptual measures of voice. COVID-19 related voice impairment was mainly associated with the decreased respiratory capacity.

Impact of Functional and Aesthetic Factors on Patient Satisfaction in Septorhinoplasty.

Objective: This study aimed to differentiate the functional or aesthetic factors affecting the result of septorhinoplasty and to determine the most important factor related to patient satisfaction. Methods: Rhinoplasty Outcome Evaluation (ROE) and Visual Analog Scale (VAS) for obstruction (VAS-O) and for appearance (VAS-A) were administered to fifty-five patients undergoing septorhinoplasty preoperatively and six months after the surgery. VAS scores were evaluated as follows: VAS-O (0: unblocked, 10: completely blocked) and VAS-A (0: worst appearance, 10: best appearance). ROE scores were calculated between 0 and 100. In order to examine the relationship between the measurements and determine the most powerful item that affects the overall ROE score, path analysis was performed, and the path coefficients were calculated. Results: The mean VAS-O and VAS-A scores before and after surgery were 6.85 and 4.36, and 3.91 and 7.22, respectively (p<0.001). The absolute value of mean difference was greater for VAS-A (-3.31) than VAS-O (-2.49), which also means appearance scores were more widely affected. The mean ROE score was increased from 46.36±9.28 to 78.85±11.70. VAS-A score had a significant impact on the overall ROE score (ß=0.782, p=0.001), while the VAS-O score had no impact. The least effective item on the overall ROE score was item 2 (ß=0.445), while the other items related to aesthetic outcome had higher Path coefficients. Conclusion: Although septorhinoplasty provides satisfactory results in both functional and aesthetic aspects, patients are more satisfied with the cosmetic outcomes.

Clinical, Prognostic, and Predictive Value of Olfactory Dysfunction for COVID-19: A Prospective Controlled Study.

OBJECTIVE: To evaluate the effect of olfactory dysfunction on the course and severity of COVID-19 and its prognostic and predictive significance for COVID-19. STUDY DESIGN: Prospective case-control study. SETTING: Ondokuz Mayis University School of Medicine. METHODS: Reverse transcription polymerase chain reaction (PCR)-positive patients, patients with COVID-19-related symptoms who had a negative PCR result, and healthy controls were included in the study. Clinicodemographic characteristics, inflammatory markers, and computed tomography stages were recorded. Disease progression and intensive care unit admission were registered. The visual analog scale (0, worst; 10, best) was used to evaluate subjective olfactory, taste, and nasal breathing ability, and the Sniffin' Sticks identification (SS-ID) test was used for psychophysical olfactory assessment. RESULTS: Mean SS-ID scores were significantly lower in the positive group (8.77) than in the negative (10.43) and healthy control (12.17) groups. VAS-smell scores were significantly lower and anosmia was more prevalent in PCR-positive patients (P < .01). SS-ID and VAS-smell scores were significantly correlated (r = 0.681, P < .001). The inflammatory parameters, pulmonary infiltration stage, disease progression, and ICU admission were not associated with SS-ID scores. A cutoff SS-ID score <9 resulted in 55.56% sensitivity in predicting COVID-19 positivity, and a cutoff VAS-smell score <8 yielded 72.22% sensitivity. CONCLUSION: Olfactory dysfunction was detected objectively and subjectively in the PCR-positive group, and no difference was found in terms of taste function and nasal breathing. The severity and prognosis of COVID-19 are not exclusively dependent on olfactory dysfunction. The degree of olfactory dysfunction can be useful in predicting PCR positivity.

Olfactory dysfunction in passive vs active smoking.

BACKGROUND: The aim of this study is to assess the olfactory functions of passive smokers compared to active smokers and nonsmokers. METHODS: This prospective case-control study included 30 nonsmokers, 30 passive smokers, and 30 active smoker participants. All groups were matched for gender and age. The Sino-Nasal Outcome Test 22 (SNOT-22) and Sniffin' Sticks test battery were administered to all subjects. Threshold (T), discrimination (D), and identification (I) scores were noted. Olfactory function was subjectively assessed as 0: severe dysfunction and 5: no problem. RESULTS: Overall, TDI scores of active smokers (24.78 ± 3.02) and passive smokers (24.90 ± 2.45) were significantly lower than nonsmokers (34.23 ± 3.46). There was no statistically significant difference between passive smokers and smokers (F (2,87) = 13.47, P < .001)). All subscores are negatively affected by active or passive smoking. The greatest impact of smoking was on threshold scores (η 2 T  = 0.719), followed by identification (η 2 I  = 0.353) and discrimination (η 2 D  = 0.282) scores. SNOT-22 and TDI scores were weakly (r = -.352) correlated as subjective assessment, and TDI scores were moderately correlated (r: .539) (P values < .001). Age and pack-years cigarette dosage had a negative effect on the TDI score (TDI = 26.386 - (0.084 × age) - (0.072 × Pack.Year)) according to stepwise linear regression model (F = 10.187; P = .001). CONCLUSIONS: Passive smoking has nearly the same adverse effect on olfactory function as active smoking. The threshold scores are the most negatively affected. The olfactory effect of cigarette smoke may not be directly related to nasal inflammation. Olfactory neuronal pathways should be investigated to elucidate the exact pathophysiology. LEVEL OF EVIDENCE: 3b.

Clinical significance of smell and taste dysfunction and other related factors in COVID-19.

PURPOSE: The objective of this study is to evaluate smell and taste dysfunction (STD) in coronavirus disease 2019 (COVID-19) positive and negative patients, and to assess the factors associated with STD in COVID-19 positive patients. METHODS: Patients who had been tested with the real-time reverse transcriptase-polymerase chain reaction (RT-PCR) for COVID-19 were identified, and according to the RT-PCR test results, patients were separated into Positive and Negative Groups. A telephone-based assessment was applied to both groups using the American Academy of Otolaryngology-Head and Neck Surgery Anosmia Reporting Tool. Patients in Positive Group were also asked to rate STD, nasal breathing, and anxiety in three different time periods (pre-/during-/post-COVID) using the visual analog scale (VAS). RESULTS: A total of 53 COVID-19 positive and 51 negative patients completed the surveys. STD was eightfold more frequent (OR 8.19; CI 95% 3.22-20.84) in the Positive Group. Of the 53 COVID-19 positive patients, 32 reported STD and 21 did not. 'Ground-glass appearance' on chest-computed tomography was more frequent and median lymphocyte count was significantly lower in COVID-19 positive patients with STD. During-COVID STD and nasal breathing VAS scores were significantly lower than the pre- and post-COVID scores. During-COVID STD scores were significantly correlated with anxiety scores (Spearman's rho-0.404, p = 0.022) but not correlated with nasal breathing scores. CONCLUSION: STD may be related to increased inflammatory response as well as damage of olfactory neuronal pathway or non-neuronal olfactory mucosa. Understanding the exact cause of chemosensory impairment in COVID-19 can be helpful in explaining the pathophysiology of the disease.

The Effect of Parental Smoking on Voice-Related Quality of Life in the Pediatric Population.

OBJECTIVES: Exposure to cigarette smoke has significant effects on the respiratory mucosa. However, little is known about the effects of household smoke exposure on children's voice-related quality of life. The aim of this study was to elucidate the effect of parental smoking (PS) on voice-related quality of life in the pediatric population. SUBJECTS AND METHODS: The Pediatric Voice-related Quality of Life (PVRQoL) instrument was administered to the parents of 104 healthy children without any known voice disorder. The children were evaluated in two groups. The first group of children had no PS history and no household smoke exposure (non-PS group), in the second group, at least one parent of the child consumed tobacco products in the house (PS group). Social emotional and physical functional subdomains of the PVRQoL were also calculated. RESULTS: A total of 104 surveys were analyzed. The overall percentage of dysphonia in the PS group was 23.6%, whereas it was 6.1% in the non-PS group. The mean PVRQoL scores were 89.1 (±13.8) in the PS group and 97.7 (±4.7) in the non-PS group (P < 0.001). The mean physical functional-PVRQoL score was 35.4 (±7.2) in the PS group and 39.0 (±6.0) in the non-PS group. The mean social emotional-PVRQoL scores were 51.2 (±9.3) in the PS group and 57.2 (±5.6) in the non-PS group. The overall voice quality was significantly lower in the PS group than in the non-PS group. CONCLUSION: Exposure to PS has negative effects on voice-related quality of life in children that cannot be underestimated. Parents should be informed about the detrimental effects of passive smoking on the voice quality of their children. Inclusion of items in pediatric voice surveys about PS that lead to dysphonia would be suggested.

A rare cause of acute severe upper airway obstruction that required endotracheal intubation: adenoid hypertrophy.

Adenoid hypertrophy is one of the common causes of upper airway obstruction in children. It usually presents with sleep-related breathing disorders and associated findings generally occur around the age of 4 years. However, the development of acute upper airway obstruction due to adenoid hypertrophy is extremely rare. Acute upper airway obstruction due to adenoid hypertrophy in a patient aged under 1 year is an extremely unexpected condition. The aim of this case report was to contribute to the literature by reporting the presence of adenoid hypertrophy causing severe acute airway obstruction leading to endotracheal intubation in a 7-month-old male patient.

Screening of dysphagia by DYMUS (Dysphagia in multiple sclerosis) and SWALQoL (Swallowing quality of life) surveys in patients with multiple sclerosis.

BACKGROUND: Dysphagia is a life-threating symptom in patients with multiple sclerosis (MS) because aspiration pneumonia develops as a consequence of swallowing disorders. Dysphagia can be detected by using patient-reported outcome measures in order to prevent complications. OBJECTIVE: To identify the dysphagia prevalence, severity, and swallowing related quality of life (QoL), by using two validated dysphagia questionnaires. METHOD: Dysphagia in Multiple Sclerosis (DYMUS) and Swallowing Quality of Life (SWALQoL) questionnaires were collected from 64 patients with MS. RESULTS: The mean total SWALQoL score was 67.9 (±11.2) and the mean DYMUS score was 2.02 (±1.3). The highest mean SWALQoL subdomain score belonged to communication (76.7 ± 15.8), and the lowest score belonged to sleep (54.2 ± 12.2). There was a significant correlation between age and DYMUS and SWALQoL scores (r: 0.539 and r: -0.610 respectively, P < .001). Additionally, there was a significant moderate correlation between disease duration and DYMUS and SWALQoL scores (r: 0.693 and r: -0.697 respectively, P < .001). DYMUS and SWALQoL scores did not vary between males and females (P > .05). Patients with secondary progressive MS had higher DYMUS and lower SWALQoL scores (more dysphagia) than in primary progressive or relapsing-type MS. There was a strong, negative and statistically significant correlation between DYMUS and total SWALQoL scores (Spearman's rho: -0.862, p < .001). CONCLUSION: MS causes dysphagia and reduces QoL. Age, disease duration, and MS type are major factors that influence SWALQoL. DYMUS and SWALQoL are well correlated. DYMUS is an easy to answer tool that may advised for screening dysphagia in patients with MS.

The interaction of gamma radiation with drugs used in cholinergic medications.

Purpose: Pharmacological medications can reduce the radiation damage in the organism when applied in the stage before or after exposure to radiation. Cholinergic drugs are a category of pharmaceutical agents acting on the neurotransmitter acetylcholine, the primary neurotransmitter in the parasympathetic nervous system. In this investigation, some gamma radiation interaction parameters namely mass attenuation coefficients (µρ), effective atomic number (Zeff) and electron densities (Nel) of 12 cholinergic system drugs have been calculated in the energy range 1 KeV-100 GeV. In addition, gamma-ray energy absorption (EABF) and exposure (EBF) of buildup factors have been computed using the five-parameter geometric progression (G-P) fitting formula for investigated drugs in the energy range 0.015-15 MeV, and for penetration depths up to 40 mean free path (mfp).Materials and methods: In order to perform these calculations, data obtained from WinXCom computer program were used. The computed µρ values were then used to calculate the effective atomic numbers and electron density of the investigated drugs. To compute the buildup factors, the G-P fitting parameters were determined by the method of interpolation from the equivalent atomic number, 'Zeq'Results and Conclusions: It has been concluded that effective atomic number and electron density of malathion is bigger than the other drugs and the variations in values of Zeff and Nel for all drugs depend on chemical compositions and photon energy where the K-absorption edge of elements may affect the energy dependence of Zeff and Nel. It should also be noted that the buildup of photons is less in malathion and carbachol and is more in tabun and parathion compared with other drugs. Photon interaction parameters evaluated in the present study may be beneficial in radiation dosimetry and therapy.

Examining alloying effect on K X ray intensity ratios and chemical shifts of the Zn, Mn and mixed spinel ferrites.

K X-ray emission spectra of Zn, Mn and mixed (Zn-Mn, Zn- Co, Zn-Ni) spinel ferrites have been acquired by inducing 59.54 keV and 22.1 keV γ-rays emitted from 3 Ci 241Am annular source and 40 mCi 109Cd point source with a HPGe detector. Some vital parameters for XRF, Kß/Kα X-ray intensity ratios, the full width at half maximum (FWHM) values, asymmetry index (As), peak energies and chemical shifts (ΔE), were defined depending on the alloying effect by working on the spectra. The obtained results exhibited that, compared to the pure states of the metals, chemical shifts aroused due to different crystal structure, valence electron structure, bond type and length in the spectrum of the alloy form. The difference of the electronegativity of the metals forming the ferrite obviously explained the change in the Kß/Kα X-ray intensity ratios. It has been concluded that the charge transfer mechanism predominates mainly and altered the intensity ratios of the metal by affecting the rearrangement of the 3d electrons in the valence band.

Effects of Oral Propolis on Mucosal Wound Healing after Endoscopic Nasal Surgery in a Rabbit Model.

OBJECTIVE: If the respiratory nasal mucosa is damaged and the mucosa does not heal properly during nasal or paranasal sinus surgery, a revision surgery may be required. The aim of this study is to investigate the effects of oral propolis application on mucosal wound healing following endoscopic nasal surgery in a rabbit model. METHODS: Twenty four New Zealand rabbits were randomly divided into three groups, namely the experimental group (EG), the control group (CG), and the negative control group (NCG). Mucosal resection was applied with 3-mm punch forceps in the bilateral ventral nasal concha in the experimental and control groups. 75 mg/kg/day propolis was added to the diet of the rabbits in the EG for 14 days. The CG continued with the standard diet postoperatively. In the NCG, no surgical intervention was made, and no dietary support was given. On postoperative day 14 all rabbits were sacrificed and left nasal specimens were examined histopathologically, hydroxyproline levels were measured in right nasal specimens. RESULTS: There were no statistically significant differences in hydroxyproline level, epithelial and subepithelial thickness, ciliary and goblet cell count, subepithelial fibrosis and collagen density between EG and CG. Neutrophil count was statistically significantly lower in EG, compared to CG (p=0.019, Tamhane test). CONCLUSION: Although there are many studies that show the positive effects of propolis on wound healing, such effect was not observed in this study. This study is deemed to constitute a unique experimental study that can be a resource for future similar studies to be performed with higher numbers of subjects and higher dosage of propolis.

Investigation of K X-ray intensity ratios of some 4d transition metals depending on the temperature.

In this paper, we have studied the intensity ratios Kß/Kα depending on the temperature for transition elements Mo, Nb, Zr and Y by 59.5keV γ-rays from a 100 mCi (241)Am radioisotope point source. The Kα and Kß emission spectra of Mo, Nb, Zr and Y were measured by using a Si (Li) solid-state detector at temperature between 40 and 400°C. σKα and σKß production cross-sections, Kß/Kα intensity ratios, asymmetry factor, energy shifts and full width half maximum (FWHM) values of the elements have been calculated. Temperature-dependent changes of the parameters are tabulated and given in the graphical forms. Based on the results obtained, Kß/Kα X-ray intensity ratios of the elements are dependent on the temperature. It is shown that σKß fluorescence cross sections of Mo, Nb and Zr have more increase rate than σKα fluorescence cross sections with increasing temperature. For Y, σKα and σKß production cross-sections firstly decrease, then increase. In general, Kß/Kα X-ray intensity ratios tend to increase with increasing temperature. Some significant shifts are observed in Kα and Kß emission spectra of Mo and Y. These results may contribute to the XRF studies of transition metals.

Determination of energy absorption and exposure buildup factors by using G-P fitting approximation for radioprotective agents.

PURPOSE: Recently, there has been an increase in interest into research into radioprotective agents. Radioprotectors are compounds that protect against radiation injury when given orally (through drinking water) prior to radiation exposure. The purpose is to achieve preferred protection of normal tissues against injury inflicted by ionizing radiation used to treat tumors. The main aim of this work is to investigate energy absorption (EABF) and exposure buildup factors (EBF) of commonly used some radioprotective agents. MATERIALS AND METHODS: We have used the Geometric Progression (G-P) fitting method for calculating the equivalent atomic number (Zeq), for EABF and EBF buildup factors of the radioprotective agents in the energy range 0.015-15 MeV for penetration depths up to 40 mean free path. RESULTS: Significant variations in both EABF and EBF values were observed for several agents at the moderate energy region. At energies below 0.1 MeV, EABF and EBF values increased with decreasing equivalent atomic number Zeq of the samples. At energies >0.15 MeV, EABF and EBF values were found to decrease with decreasing Zeq of all agents. In addition, EABF and EBF were the largest for carnosin, tempol, melatonin, interferon gamma and orientine at 0.05 and 0.06 MeV, respectively, and the minimum values of buildup factors were at 0.1 MeV for cysteine, amifostine, penicillamine and glutathione. CONCLUSIONS: Cysteine and amifostine are good compounds for gamma rays absorption applications among the selected compounds. The presented results in this study are expected to be helpful in radiation dosimetry.

Thyroglossal Duct Cyst in a 3-Month-Old Infant: A Rare Case.

Thyroglossal duct cyst (TGDC) is the most common congenital midline neck mass in children. It usually becomes symptomatic following a respiratory tract infection and is usually diagnosed at 5 years of age. Thyroglossal duct cyst is rarely observed in less than 1-year-old infants. In this study, we present a 3-month-old infant with TGDC, who was administered multiple courses of antibiotic therapy for the hyperemic, draining, midline neck mass that had existed since he was 15 days old. Physical examination revealed an infrahyoid midline neck mass measuring 3×3 cm, which moved while swallowing and had a sinus opening in the overlying skin. The patient underwent Sistrunk operation under general anesthesia. Histopathologic examination revealed TGDC. One-year follow-up revealed no recurrence.

Photon buildup factors of some chemotherapy drugs.

Everyday more and more people are diagnosed with some form of cancer. Some are treatable with chemotherapy alone, while others need radiotherapy and occasionally surgery. Recently, concurrent administration of chemotherapy and radiotherapy has been increasingly used in cancer treatment, leading to improvements in survival as well as quality of life. Accordingly, interaction of chemotherapy drugs with radiation will be meaningful to examine. In the present study, gamma ray energy absorption and exposure of buildup factors were computed using the five-parameter geometric progression (G-P) fitting formula for some chemotherapy drugs in the energy range 0.015-15 MeV, and for penetration depths up to 40 mean free path (mfp). The generated energy absorption (EABF) and exposure buildup factors (EBF) of chemotherapy drugs have been studied as a function of penetration depth and incident photon energy. The significant variations in EABF and EBF for chemotherapy drugs have been observed at the moderate energy region. It has been concluded that the buildup of photons is less in azathioprine and is more in vinblastine compared with other drugs. Buildup factors investigated in the present work could be useful in radiation dosimetry and therapy.

Endoscopic removal of giant intranasal schwannoma.

Schwannoma is a benign neoplasm originating from schwann cells of the peripheral nerve sheath. Although nearly half of all schwannomas involve the head and neck region, nasal and paranasal sinus presentations are very rare in the literature. We present a case of nasal schwannoma originating from the right nasal cavity. A 59-year-old man presented with complaints of progressive right nasal obstruction and headache. Endoscopic examinations revealed a mass that filled the right middle meatus. At first glance, it was not like polyp tissue. Endoscopic sinus surgery was performed under general anesthesia, and the mass was completely removed.

A study of the energy absorption and exposure buildup factors of some anti-inflammatory drugs.

Human radiation exposure is increasing due to radiation development in science and technology. The development of radioprotective agents is important for protecting patients from the side effects of radiotherapy and for protecting the public from unwanted irradiation. Radioprotective agents are used to reduce the damage caused by radiation in healthy tissues. There are several classes of radioprotective compounds that are under investigation. Analgesics and anti-inflammatory compounds are being considered for treating or preventing the effects of damage due to radiation exposure, or for increasing the chance of survival after exposure to a high dose of radiation. In this study, we investigated the radioprotective effects of some analgesic and anti-inflammatory compounds by evaluating buildup factors. The gamma ray energy absorption (EABF) and exposure buildup factors (EBF) were calculated to select compounds in a 0.015-15 MeV energy region up to a penetration depth of 40 mfp (mean free path). Variations of EABF and EBF with incident photon energy and penetration depth elements were also investigated. Significant variations in both EABF and EBF values were observed for several compounds at the moderate energy region. At energies below 0.15 MeV, EABF and EBF values increased with decreasing equivalent atomic number (Z(eq)) of the samples. In addition, EABF and EBF were the largest for ibuprofen, aspirin, paracetamol, naproxen and ketoprofen at 0.05 and 0.06 MeV, respectively, and the EABF value was 0.1 MeV for aceclofenac. From these results, we concluded that the buildup of photons is less for aceclofenac compared to other materials.
