Sarcopenia accompanied by systemic inflammation can predict clinical outcomes in patients with head and neck cancer undergoing curative therapy.

Objectives: Evaluation of sarcopenia accompanied by systemic inflammation status is a more beneficial prognostic marker than sarcopenia alone in various cancers. However, few studies have focused on this combination in patients with head and neck squamous cell cancer (HNSCC). In this study, we investigated how the combination of sarcopenia and systemic inflammation could affect survival in patients with HNSCC. Moreover, we explored which systemic inflammation markers could be better prognostic indicators when accompanied by sarcopenia. Materials and methods: We retrospectively reviewed the medical records of patients with HNSCC treated between 2012 and 2016. Sarcopenia was defined by the skeletal muscle area measured on a computed tomography image slice at the level of the third cervical vertebra. The neutrophil/lymphocyte, platelet/lymphocyte, and lymphocyte/monocyte ratios (NLR, PLR, and LMR, respectively) were used as systemic inflammation markers that were combined with sarcopenia to evaluate prognosis. Results: A total of 100 patients were enrolled, and 71 patients were considered sarcopenia. Patients with sarcopenia had significantly lower LMR and higher NLR and PLR. They also showed worse overall survival (OS) and progression-free survival (PFS). The comparative assessment of multiple combination patterns of sarcopenia and systemic inflammation indices proved that sarcopenia plus LMR considered as most reliable indicator for prognosis in HNSCC patients. Sarcopenia plus low LMR was a significantly poor prognostic factor both for OS and PFS with greater HR values than sarcopenia alone. Conclusions: The combination of sarcopenia and LMR was considered the most sensitive prognostic factor in patients with HNSCC, suggesting it might be beneficial for identifying poor outcome risks.

Prediction of Cochlear Implant Effectiveness With Surface-Based Morphometry.

OBJECTIVE: This study aimed to determine whether surface-based morphometry of preoperative whole-brain three-dimensional T1-weighted magnetic resonance imaging (MRI) images can predict the clinical outcomes of cochlear implantation. STUDY DESIGN: This was an observational, multicenter study using preoperative MRI data. SETTING: The study was conducted at tertiary care referral centers. PATIENTS: Sixty-four patients with severe to profound hearing loss (≥70 dB bilaterally), who were scheduled for cochlear implant (CI) surgery, were enrolled. The patients included 19 with congenital hearing loss and 45 with acquired hearing loss. INTERVENTIONS: Participants underwent CI surgery. Before surgery, high-resolution three-dimensional T1-weighted brain MRI was performed, and the images were analyzed using FreeSurfer. MAIN OUTCOME MEASURES: The primary outcome was monosyllable audibility under quiet conditions 6 months after surgery. Cortical thickness residuals within 34 regions of interest (ROIs) as per the Desikan-Killiany cortical atlas were calculated based on age and healthy-hearing control regression lines. RESULTS: Rank logistic regression analysis detected significant associations between CI effectiveness and five right hemisphere ROIs and five left hemisphere ROIs. Predictive modeling using the cortical thickness of the right entorhinal cortex and left medial orbitofrontal cortex revealed a significant correlation with speech discrimination ability. This correlation was higher in patients with acquired hearing loss than in those with congenital hearing loss. CONCLUSIONS: Preoperative surface-based morphometry could potentially predict CI outcomes and assist in patient selection and clinical decision making. However, further research with larger, more diverse samples is necessary to confirm these findings and determine their generalizability.

Bilobed Flap for Reconstruction of Skin Defects after Excision of Parotid Carcinoma: A Case Report.

OBJECTIVES: Local flaps, pedicled flaps, and free flaps are used to reconstruct medium-sized skin defects after excision of parotid carcinoma. The bilobed flap is a local flap primarily used by plastic surgeons for small defects of nasal skin. We report a case of parotid carcinoma with skin infiltration successfully treated by skin reconstruction with a bilobed flap. METHODS: An 84-year-old man presented with a parotid mass he had noticed 2 months earlier. Parotid carcinoma with skin infiltration was diagnosed and he underwent radical surgery. The skin defect was round (diameter, 6 cm) and was resected and reconstructed with a bilobed flap designed to be caudal to the defect. RESULTS: Postoperative facial nerve palsy improved within 6 months. The postoperative course was otherwise uneventful, and the patient was discharged on postoperative day 7. Pathological examination revealed a sarcomatoid salivary duct carcinoma. CONCLUSIONS: Bilobed flaps are useful for reconstructing skin defects with a diameter of 6 cm or less.

Association between atherosclerosis, hearing recovery, and hearing in the healthy ear in idiopathic sudden sensorineural hearing loss: a retrospective chart analysis.

Atherosclerosis is reported to be a risk factor for the severity of idiopathic sudden sensorineural hearing loss (ISSNHL). We evaluated the hypothesis that atherosclerosis affects the hearing thresholds of both the affected and healthy sides of ISSNHL patients. We conducted multivariate analyses on retrospectively collected data of patients with ISSNHL (N = 762) to evaluate the relationship between known factors linked to atherosclerosis and hearing thresholds on affected and healthy sides and whether these factors are prognostic for hearing recovery. Older ages, vertigo or dizziness, diabetes mellitus, and congestive heart failure were significantly related to higher hearing thresholds on the affected side. Older ages, male, and vascular disease were significantly related to higher hearing thresholds on the healthy side. Vertigo or dizziness, severe hearing loss and hearing loss at high frequencies on the affected side, higher hearing thresholds on the healthy side, regular anticoagulant medication, and delayed steroid treatment were significantly related to lack of recovery. Since several atherosclerosis-related factors are associated with higher hearing thresholds on both affected and healthy sides in ISSNHL and higher hearing thresholds on the healthy side predict poorer prognosis, diagnosis, and predicting prognosis of ISSNHL may benefit from rigorous evaluation of patients' cardiovascular comorbidities and hearing levels on both the healthy and affected sides.

Effects of hearing aids in patients with unilateral tinnitus with acquired ipsilateral sensorineural hearing loss.

OBJECTIVES: To evaluate the effectiveness of sound therapy using hearing aids in patients experiencing tinnitus with acquired unilateral sensorineural hearing loss. METHODS: A total of 97 patients with unilateral tinnitus with acquired ipsilateral sensorineural hearing loss were included. Evaluation involved self-report questionnaires administered at entry, 3 months after treatment, and 1 year after treatment. RESULTS: The mean Tinnitus Handicap Inventory score before treatment decreased significantly (p < 0.01) at 3 months (50.0 ± 24.5-12.7 ± 16.2), and 1 year (53.3 ± 25.5-8.79 ± 13.9), after treatment. Moreover, the visual analog scale score decreased significantly at 3 months (loudness, 69.6 ± 21.9-29.1 ± 27.2; annoyance, 71.1 ± 24.7-22.7 ± 25.5) and 1 year (loudness, 69.8 ± 22.0-21.1 ± 26.1; annoyance, 72.7 ± 25.6-19.4 ± 27.6). Approximately 80-90% of patients noticed improvements in tinnitus annoyance and loudness, as determined by their responses to the questionnaires of subjective symptom improvement. CONCLUSIONS: Hearing aids are remarkably effective for patients with unilateral tinnitus with acquired ipsilateral sensorineural hearing loss.

Utility of computed tomography findings as a predictor of carotid artery invasion by metastatic lymph nodes in head and neck squamous cell carcinoma.

PURPOSE: Carotid artery invasion by metastatic lymph nodes in head and neck squamous cell carcinoma (HNSCC) is one of the diagnostic criteria for unresectable tumors. However, to date, the diagnostic criteria for carotid artery invasion have not been well documented. This study investigated the utility of computed tomography (CT) findings as a predictor of carotid artery invasion by metastatic lymph nodes in HNSCC. METHODS: Twenty-eight patients who had metastatic lymph nodes of HNSCC attached to the carotid artery as seen on CT images before neck dissection from January 2011 to November 2017 were included. Five imaging parameters (angle of contact [AC], length of contact [LC], haziness of the carotid artery wall [HW], size of the lymph node, and involvement of the bifurcation of the carotid artery [IB]) were assessed using CT to predict carotid artery invasion. Furthermore, the utility of the combination of these five parameters was evaluated. RESULTS: There were significant differences in AC, LC, and IB between patients with and without carotid artery invasion. There were significant differences in all combinations of the two image findings between patients with and without carotid artery invasion. In particular, the combinations of LC and HW, and LC and IB could clearly predict carotid artery invasion. CONCLUSION: AC, LC, and IB were useful predictors of carotid artery invasion of metastatic lymph nodes in HNSCC. This study is the first to report that IB is a useful predictor of carotid artery invasion in HNSCC.

Severe sudden sensorineural hearing loss related to risk of stroke and atherosclerosis.

The cause of idiopathic sudden sensorineural hearing loss (idiopathic SSNHL)-diagnosed after excluding other causes of hearing loss, such as SSNHL associated with vestibular schwannoma (VS)-is unknown. The presumed pathogenesis of idiopathic SSNHL includes circulatory disorders (e.g., cochlear infarction). We tested the hypothesis that patients with SSNHL who are at high stroke risk will have a lower rate of VS compared to those with low stroke risk. The rationale is that the primary cause of SSNHL in patients with high stroke risk might be a circulatory disturbance. We conducted a retrospective study in six hospitals. Our sampling of SSNHL patients included those diagnosed with idiopathic SSNHL and VS-associated SSNHL. SSNHL patients who had a head MRI were stratified by severity of hearing loss and evaluated for differences in the detection rate of VS between the high-scoring CHADS2 (CHADS2-H-), an index of stroke risk, and low-scoring CHADS2 (CHADS2-L-) groups. We identified 916 patients who met the inclusion criteria. For severe hearing loss, the CHADS2-H group had a significantly lower rate of VS than the CHADS2-L group (OR 0 [95% CI 0.00-0.612]; P = 0.007). These results indirectly support the hypothesis that a primary cause of severe idiopathic SSNHL in those at high risk of stroke might be a circulatory disorder.

Effectiveness of hearing aids in treating patients with chronic tinnitus with average hearing levels of <30 dBHL and no inconvenience due to hearing loss.

BACKGROUND: The effectiveness of hearing aids for tinnitus patients without hearing loss in conversation-comprehension range and inconvenience in daily communication is unknown. OBJECTIVE: We aimed to evaluate their therapeutic effect. MATERIALS AND METHODS: We included 91 patients with average hearing levels <30 dBHL. To determine the effects, self-reported questionnaires were used. Data were collected at the entry and 3 months (n = 91) and 1 year (n = 70) after treatment initiation. RESULTS: All scores (mean ± standard deviation) decreased significantly (p < 0.0001) from before treatment to 3 months and 1 year after treatment: tinnitus handicap inventory score: from 56 ± 21 to 17 ± 17 and 13 ± 15; visual analogue scale (VAS) score for tinnitus loudness: from 71 ± 20 to 31 ± 26 and 28 ± 29; VAS score for tinnitus annoyance: 79 ± 20 to 27 ± 25 and 26 ± 30, respectively. Approximately 90% of patients noticed improvements in tinnitus annoyance and loudness, as determined by the questionnaires regarding subjective symptom improvement. CONCLUSIONS: Hearing aids may be useful for tinnitus patients without hearing loss and inconvenience in daily communication. SIGNIFICANCE: Our findings provide a treatment option for tinnitus patients with an average hearing level of <30 dBHL.

Labyrinthine destruction caused by inflammatory pseudotumor of the temporal bone: A report of three cases and review of the literature.

BACKGROUND: Inflammatory pseudotumors (IPTs) are rare, idiopathic, and inflammatory lesions that are histopathologically benign. Here, we present three cases of labyrinthine destruction caused by an IPT. METHODS: The first patient was a 74-year-old male with a mass lesion extending from the inner ear to the external ear canal. The second patient was a 62-year-old female with a foliated polycystic lesion in the petrous bone on the dorsal side of the left internal auditory canal. The third patient was a 68-year-old female with a mass extending from the inner ear to the middle ear, destroying the semicircular canal and cochlea. RESULTS: In two cases, we performed surgical resection successfully with no recurrence. In the other case, the lesion showed shrinkage after chemotherapy for colorectal cancer incidentally found during the examination process. CONCLUSION: Surgical technique and indication for IPT should be based on the location and function of the lesion. In addition, there is room to consider pharmacotherapy as a treatment option for IPT of the temporal bone. LEVEL OF EVIDENCE: 4.

Trapezius muscle branch of the spinal accessory nerve without penetrating the sternocleidomastoid muscle as a pitfall in neck dissection: prevalence in a Japanese institution and a protocol for the prevention of iatrogenic injury.

BACKGROUND: The spinal accessory nerve (SAN) has several anatomical variations, which may be a pitfall in neck dissection (ND). These include the trapezius muscle branch (TB), which stems from the common trunk before entering the sternocleidomastoid muscle (SCM). AIMS/OBJECTIVES: To investigate the prevalence of this variation and suggest a protocol for preventing unexpected injury of the TB in ND. MATERIALS AND METHODS: We conducted a retrospective cohort study for 93 patients who had undergone neck dissection (117 sides) without resection of the SCM nor SAN. We recorded the division of the TB after and before penetration of the SCM by the common trunk (penetrating type TB [PTB]) and non-penetrating type TB [NPTB], respectively). RESULTS: Among NDs, PTB and NPTB were observed in 61 (52%) and 56 (48%) sides, respectively. In the subgroup of 24 cases with bilateral ND, PTB/PTB, NPTB/NPTB, and NPTB/PTB were observed in eight (33%), nine (38%), and seven (29%) cases, respectively. The prevalence of PTB/NPTB did not differ according to age, sex, or laterality. CONCLUSIONS AND SIGNIFICANCE: NPTB is a common anatomical variation. The presence or absence of a branch from the common trunk must be initially checked to avoid unexpected damage to the TB.

Sudden sensorineural hearing loss in patients with vestibular schwannoma.

Clinical features of sudden sensorineural hearing loss (SSNHL) associated with vestibular schwannoma (VS) are not fully understood. Determining a treatment plan and explaining it to patients requires clinicians to clearly understand the clinical features related to the tumor, including SSNHL. To identify the full range of clinical features of VS-associated SSNHL, especially recovery of hearing following multiple episodes of SSNHL and what factors predict recovery and recurrence. A multicenter retrospective chart review was conducted in seven tertiary care hospitals between April 1, 2011, and March 31, 2020. We collected and analyzed dose of administered steroid, pure-tone audiometry results, and brain MRIs of patients diagnosed with VS-associated SSNHL. Seventy-seven patients were included. They experienced 109 episodes of audiogram-confirmed SSNHL. The highest proportion of complete recoveries occurred in patients with U-shaped audiograms. The recovery rates for the first, second, and third and subsequent episodes of SSNHL were 53.5%, 28.0%, and 9.1%, respectively. Recovery rate decreased significantly with increasing number of SSNHL episodes (P =0 .0011; Cochran-Armitage test). After the first episode of SSNHL, the recurrence-free rate was 69.9% over 1 year and 57.7% over 2 years; the median recurrence time was 32 months. Logarithmic approximation revealed that there is a 25% probability that SSNHL would recur within a year. SSNHL in patients with VS is likely to recur within one year in 25% of cases. Also, recovery rate decreases as a patient experiences increasing episodes of SSNHL.

Effective sound therapy using a hearing aid and educational counseling in patients with chronic tinnitus.

OBJECTIVE: This study aimed to assess the effectiveness of our sound therapy with appropriate hearing aid fitting and periodic hearing aid adjustment in patients with chronic tinnitus. METHODS: We conducted a retrospective study. The study included 490 individuals who received treatment with hearing aids for chronic tinnitus at least for 3 months. To determine the effects of tinnitus on patients' quality of life, the participants completed a series of questionnaires, including the Tinnitus Handicap Inventory (THI), Visual Analogue Scale (VAS) for loudness and annoyance, and questionnaires of subjective symptom improvement. Data were collected at entry and 3 months and 1 year after treatment initiation. RESULTS: All 490 participants completed the questionnaires at 3 months; however, only 312 completed them at 1 year. The mean ± standard deviation THI score before treatment decreased significantly at 3 months (490 participants: 53 ± 25 to 11 ± 16 and 312 participants: 55 ± 24 to 12 ± 16) and 1 year (55 ± 24 to 9 ± 14) (P < 0.01). The mean VAS score for tinnitus loudness before treatment decreased significantly at 3 months (490 participants: 70 ± 22 to 25 ± 27 and 312 participants: 71 ± 22 to 27 ± 26) and 1 year (71 ± 22 to 21 ± 28) (P < 0.01). In addition, the mean VAS score for tinnitus annoyance before treatment decreased significantly at 3 months (490 participants: 75 ± 26 to 20 ± 26 and 312 participants: 75 ± 25 to 23 ± 27) and 1 year (75 ± 25 to 17 ± 26) (P < 0.01). Approximately 80% of patients noticed improvements in their tinnitus annoyance and loudness, as determined by their responses to the questionnaires of subjective symptom improvement. CONCLUSION: The results of this study suggest that treatment with sound therapy may ameliorate the symptoms of chronic tinnitus associated with hearing loss.

Early hearing improvement predicts the prognosis of idiopathic sudden sensorineural hearing loss.

PURPOSE: To determine pre- and post-treatment factors that are useful for predicting the prognosis of hearing improvement in idiopathic sudden sensorineural hearing loss (ISSHL). METHODS: This retrospective study included 332 patients with ISSHL. Patients received intravenous steroid treatment (prednisolone sodium succinate; 120 mg/day followed by dose tapering). Complete recovery of hearing levels was defined as a final pure-tone audiometry of ≤ 20 dB HL or the same level as the contralateral ear. Patients' age; sex; side of hearing loss; initial hearing level; days from onset to treatment; presence of vertigo, diabetes, and hypertension; and hearing improvement on days 3-4 and 6-7 after treatment initiation were analyzed as potential prognostic factors. RESULTS: Overall, 109 patients (32%) had complete recovery. Results of the multivariate logistic regression model identified age (odds ratio [OR] = 0.974), initial hearing level (OR = 0.949), vertigo (OR = 0.409), and hearing improvement on days 6-7 after treatment initiation (OR = 1.11) as significant independent predictors of complete recovery. Age ≥ 60 years, initial hearing level ≥ 72.5 dB HL, and vertigo contributed to poor prognosis. Patients without these three factors and a hearing improvement of ≥ 10 dB HL on days 6-7 post-treatment had a complete recovery rate of 80%. Only 1.5% of the patients with 2-3 of these factors and a hearing improvement of < 10 dB HL on days 6-7 after treatment initiation achieved complete recovery. CONCLUSION: Age, initial hearing level, vertigo, and hearing improvement on days 6-7 after treatment initiation were independent predictors of hearing recovery in ISSHL.

Personality and Sleep Evaluation of Patients with Tinnitus in Japan.

In Japan, there have been no examinations of tinnitus with respect to personality traits, and only a few studies have investigated sleep disorders in tinnitus. Understanding the association between these can aid in selecting and developing effective treatment options for patients with tinnitus. This study aimed to clarify the relationship between tinnitus severity, personality, and sleep disorders, in patients with chronic tinnitus in Japan. We retrospectively evaluated the personality factors of 56 patients presenting with tinnitus using the NEO Five-Factor Inventory (NEO-FFI), which examines five personality characteristics, including Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness. We evaluated tinnitus severity, sleep disorders, depression, and anxiety using the Tinnitus Handicap Inventory, Pittsburgh Sleep Quality Index (PSQI), Self-Rating Depression Scale, and State-Trait Anxiety Inventory, respectively. Neuroticism and tinnitus severity were positively correlated (r = 0.548, p < 0.001). Sleep disorders were observed in 73.2% of patients; however, there was no correlation between the PSQI score and tinnitus severity or between PSQI score and scores of the five NEO-FFI items. Sleep disorders are frequently experienced by patients with chronic tinnitus, regardless of tinnitus severity or personality. Understanding the relationship between personality and tinnitus severity could lead to better management of tinnitus.

The Frequency Characteristic of Silicone Domes in Receiver in the Canal Hearing Aids.

BACKGROUND: There are several types of silicone domes in receiver in the canal hearing aids (RICs), which have different occlusion levels. However, the frequency characteristics of each type of silicone dome are unclear. PURPOSE: This study aimed to determine the frequency characteristics of three types of silicone domes (open domes, double-type power domes, and tulip domes) in RICs. RESEARCH DESIGN: This is an interventional study. STUDY SAMPLE: In total, 11 participants with a normal sense of hearing were prospectively enrolled. INTERVENTION: Participants were fitted with hearing aids, which were adjusted to similar settings, and only the silicone domes were changed. The acoustic gain of hearing aids was adjusted to 20 dB in the range of 250 Hz to 4 kHz using the 2-cc coupler. DATA COLLECTION AND ANALYSIS: We measured the real-ear aided gain (REAG) for each type of silicone dome. In each frequency, we statistically compared the REAG of each type of dome. Acoustic gain using the Open Fit coupler of each type of dome was also measured. RESULTS: The REAG was obtained with no leakage with open domes only at 2 kHz, and with tulip domes and double-type power domes in the range of 1 to 2 kHz. Double-type power domes obtained significantly higher REAG than tulip domes at 250 and 500 Hz. Under the Open Fit coupler, all types obtained higher acoustic gain than the REAG. CONCLUSION: This study provides the analysis of the frequency characteristics of silicone domes in RICs. The highest degree of occlusion was observed in double-type power domes, followed by tulip domes, and the lowest was observed in open domes.

Factor analysis and evaluation of each item of the tinnitus handicap inventory.

PURPOSE: This study aims to examine the availability of subscales in the Tinnitus Handicap Inventory (THI) originally proposed by Newman and the possibility of other useful subscales. We also examine whether each item of the THI could be used to better understand the status of patients with tinnitus. METHODS: This study included 1332 patients who answered the THI on their first visit. Confirmatory factor analysis was conducted to the 25 items of the THI to confirm the usefulness of the emotional, functional, and catastrophic subscales. Exploratory factor analysis was performed to discover the availability of other suitable subscales in addition to the proposed subscales. The proportion of patients who chose "yes" in each item of the THI was also examined to understand the status of patients with tinnitus. RESULTS: In the confirmatory factor analysis, the emotional, functional, and catastrophic subscales did not fit the model. In the exploratory factor analysis, data were extremely biased to one factor. Examination of each item of the THI showed the tendency of worsening of comorbid symptoms when tinnitus handicap became worse. CONCLUSIONS: As a result of the factor analysis, only the total score, not any subscale, would be clinically useful in the THI. Examination of each item of the THI was helpful to understand the status of patients with tinnitus and comorbid symptoms of tinnitus. It is necessary to consider treatment by taking these comorbid symptoms into account.

The Molecular Identification and Antifungal Susceptibilities of Aspergillus Species Causing Otomycosis in Tochigi, Japan.

Aspergillus species are the most common pathogenic fungi involved in otomycosis, an infection of the outer ear canal. In this study, we examined the incidence of Aspergillus infections and the antifungal susceptibilities of 30 Aspergillus species isolates from patients with otomycosis who visited Saiseikai Utsunomiya Hospital between August 2013 and July 2016. Based on the morphological test results, the strains were identified as Aspergillus niger sensu lato (20 strains), A. terreus sensu lato (7 strains), and A. fumigatus sensu lato (3 strains). In contrast, the molecular identifications based on analyzing the isolates' partial ß-tubulin gene sequences revealed them to be A. niger sensu stricto (12 strains), A. tubingensis (8 strains), A. terreus sensu stricto (7 strains), and A. fumigatus sensu stricto (3 strains). The antifungal susceptibility test results indicated that strains of A. tubingensis and A. niger sensu stricto displayed lower susceptibilities to ravuconazole, compared with the other isolates. The Aspergillus strains from this study showed low minimum inhibitory concentrations toward the azole-based drugs efinaconazole, lanoconazole, and luliconazole. Therefore, these topical therapeutic agents may be effective for the treatment of otomycosis.

Effects of tinnitus treatments on sleep disorders in patients with tinnitus.

OBJECTIVE: To assess the effects of tinnitus treatments on sleep disorders in patients with tinnitus. DESIGN: Subjects completed the Pittsburg Sleep Quality Index (PSQI), Tinnitus Handicap Inventory (THI), Self-rating Depression Scale (SDS), and State Trait Anxiety Inventory (STAI). The questionnaire results and the patients' sex, age, time since the onset of tinnitus, and mean hearing level were examined, and differences between a sleep disorder group and a normal sleep group were examined. Patients completed the questionnaires again after initiating tinnitus treatments (counselling and use of sound generators), and the change in questionnaire scores at follow-up was evaluated. STUDY SAMPLE: Patients (N = 100) with tinnitus who visited Keio University Hospital and started treatment without medication between 2005 and 2008. RESULTS: Sixty-six percent of the patients had sleep disorders. Compared with patients without sleep disorders, patients with sleep disorders had significantly higher SDS and STAI scores at the first visit. The mean PSQI scores showed significant improvement at follow-up. CONCLUSIONS: Sleep disorders in patients with tinnitus improved after tinnitus treatments. Complex interactions between depressive symptoms and anxiety may occur in these patients. The improvement in sleep disorders at follow-up was correlated with improvements in tinnitus severity and state anxiety.

Pre-therapeutic nutritional assessment for predicting severe adverse events in patients with head and neck cancer treated by radiotherapy.

BACKGROUND & AIMS: Malnutrition is common in patients with head and neck cancer (HNSCC). It may be related to severe adverse toxicity as a result of radiotherapy. The aim was to investigate nutritional screening factors for severe adverse events. METHODS: A retrospective chart review of 101 patients who underwent radiotherapy from 2009 to 2013 was performed. The relationships among severe adverse events and pretreatment nutritional parameters, including static variables (serum albumin, total protein, total lymphocyte counts, body mass index), dynamic variables (retinol-binding protein, transferrin, pre-albumin), and nutritional screening tools (Onodera's Prognostic Nutrition Index [O-PNI]; Nutrition Risk Index; Controlling Nutritional Status [CONUT] score; Nutritional Risk Screening 2002) were evaluated in addition to patient and treatment factors. RESULTS: According to the static parameters, approximately 30% of patients were malnourished before treatment. Twenty-four patients exhibited severe adverse events. On univariate analysis, combined chemotherapy, advanced staging, O-PNI <40, and CONUT score ≥5 were significant predictors of severe adverse events. Multivariate analysis revealed that O-PNI <40 and combined chemotherapy independently predict severe adverse events. CONCLUSIONS: O-PNI is considered a useful nutritional factor for predicting severe adverse events in HNSCC patients undergoing chemoradiotherapy and facilitates the planning of aggressive nutritional interventions prior to treatment.
