Perivascular Epitheloid Cell Tumor (PEComa) of the Neck.

Perivascular epitheloid cell tumors (PEComas) are a family of neoplasms with distinctive perivascular epitheloid cells. 36 year old female patient admitted to our clinic with a mass on neck. Biopsy was reported as PEComa. PEComas are very rare, especially in neck region. Here, we present the second case in literature.

Long-term efficacy of tonsillectomy/adenotonsillectomy in patients with periodic fever aphthous stomatitis pharyngitis adenitis syndrome with special emphasis on co-existence of familial Mediterranean fever.

Periodic fever, aphthous stomatitis, pharyngitis, adenitis (PFAPA) syndrome is one of the most common autoinflammatory fever disorders in the childhood which may co-exists with familial Mediterranean fever (FMF) causing treatment complexity. As the role of surgery in PFAPA syndrome is still controversial, in this paper, our aim is to present our results of tonsillectomy/adenotonsillectomy in the treatment of PFAPA syndrome. Archives of a tertiary care hospital were investigated for patients who underwent tonsillectomy or adenotonsillectomy due to PFAPA Syndrome between 2010 and 2020. 344 patients were found but only 281 of them were accessible. Through phone call interview and chart review methods, preoperative and postoperative the number and severity of the attacks and general satisfaction after the operation were recorded and analyzed. Also, patients with concomitant FMF were analyzed separately. A total of 281 patients were included in the study. There was no improvement in 10 (3.55%) patients. Eight (2.84%) patients showed mild improvement, 29 (10.32%) patients had moderate improvement and 234 (83.27%) patients had full recovery after tonsillectomy. There were 266 PFAPA patients without FMF. No improvement, mild improvement, moderate improvement, and full recovery in this patient group were 5 (1.9%), 6 (2.3%), 25 (9.4%) and 230 (86.5%), respectively. FMF was present in 5.33% (15/281) of the patients. In PFAPA + FMF group 5 patients had no improvement (33.3%), 2 had mild improvement (13.3%), 4 had moderate improvement (26.7%) and 4 had full recovery (26.7%). Benefit of tonsillectomy was significantly lower in the patients with concomitant FMF when compared to the patients who did not have FMF (p < 0.001). Age of diagnosis, age of operation, severity of the disease, type of operation, and gender were found to have no significant relationship with the benefit from surgery (p < 0.05). According to the findings of this study, tonsillectomy is an effective long-term treatment for PFAPA syndrome with success rate of 83.27%. Also, preoperatively FMF should be considered in these patients, which dramatically reduces surgical efficacy.

Does size of the cochlear nerve affect postoperative auditory performance in pediatric cochlear implant patients with normal cochlear nerves? / O tamanho do nervo coclear afeta o desempenho auditivo pós-operatório em pacientes pediátricos com implante coclear e nervos cocleares normais?

Abstract Introduction Cochlear implantation is an effective treatment method for severe to profound hearing loss. Many factors that may influence cochlear implantation success have been explained in previous studies. Apart from those, minor differences in size of normal cochlear nerves may affect postoperative performance. Objective To investigate whether the minor differences in cochlear nerve size in normal cochlear nerves affect postoperative cochlear implant performance. Methods 30 pediatric prelingually deaf patients who were treated with cochlear implantation were included in this study. From the reconstructed parasagittal magnetic resonance images, the diameter and cross-sectional area of the cochlear nerve on the ipsilateral and contralateral side were measured. Auditory evaluations were performed 1, 3, 6 and 12 months following the first fitting. All the analysis was performed by using EARS®, evaluation of auditory responses to speech tool. Correlation between cochlear nerve diameter, cross-sectional area and postoperative auditory perception was analyzed to determine whether variation in cochlear nerve size contributes to postoperative auditory performance. Results The mean diameter of the cochlear nerve on the ipsilateral side was 718.4 μm (504.5 − 904.3 μm) and mean cross sectional area was 0.015 cm2 (0.012 − 0.018 cm2). On the contralateral side the mean cochlear nerve diameter was 714.4 μm (502.6 − 951.4 μm) and mean cross sectional area was 0.014 cm2 (0.011 − 0.019 cm2). The correlation between the diameter and cross-sectional area of the ipsilateral and contralateral cochlear nerve revealed no significance. Mean score at first month monosyllable-trochee-polysyllable test, MTP1, was 0.17 (0.08 − 0.33), at 6th month with 6 words test, 6th month MTP6 was 0.72 (0.39 − 1.0), at 6th month with 12 words, 6th month MTP 12 was 0.46 (0.17 − 0.75) and at 12th month with 12 words, 12th month MTP12 was 0.73 (0.25 − 1.0). There was no correlation between the monosyllable-trochee-polysyllable test, values at any time with the diameter of the ipsilateral cochlear nerve. However, the first month MTP, 6th month MTP6 and 12th month MTP12 correlated with the cross-sectional area of the ipsilateral cochlear nerve. Conclusion Measuring the cross sectional area of the normal- appearing cochlear nerve may give important prognostic knowledge on cochlear implant outcomes. In patients with a larger cross sectional area the auditory performance was better and faster. Although normal appearing, slight differences on cross sectional area of the cochlear nerve may affect performance. Measuring the size of the cochlear nerve on parasagittal magnetic resonance images may provide beneficial information on the postoperative rehabilitation process.

Resumo Introdução O implante coclear é um método de tratamento eficaz para a perda auditiva grave a profunda. Muitos fatores que podem influenciar o sucesso do implante coclear foram explicados em estudos anteriores. Além desses fatores, pequenas diferenças no tamanho dos nervos cocleares normais podem afetar o desempenho pós-operatório. Objetivo Investigar se pequenas diferenças no tamanho dos nervos cocleares normais afetam o desempenho pós-operatório do implante coclear. Método Foram incluídos neste estudo 30 pacientes pediátricos surdos pré-linguais, tratados com implante coclear. A partir de imagens de ressonância magnética parassagitais reconstruídas, foram medidos o diâmetro e a área de seção transversal do nervo coclear no lado ipsilateral e contralateral. As avaliações auditivas foram feitas 1, 3, 6 e 12 meses após a primeira adaptação. Todas as análises foram feitas com a ferramenta EARS® (do inglês evaluation of auditory responses to speech). A correlação entre o diâmetro do nervo coclear, a área transversal e a percepção auditiva pós-operatória foi analisada para determinar se a variação no tamanho do nervo coclear contribui para o desempenho auditivo pós-operatório. Resultados O diâmetro médio do nervo coclear no lado ipsilateral foi de 718,4 μm (504,5 a 904,3 μm) e a área da seção transversal média foi de 0,015 cm2 (0,012-0,018 cm2). No lado contralateral, o diâmetro médio do nervo coclear foi de 714,4 μm (502,6 a 951,4 μm) e a área da seção transversal média foi de 0,014 cm2 (0,011 a 0,019 cm2). A correlação entre o diâmetro e a área transversal do nervo coclear ipsilateral e contralateral não revelou qualquer significância. O escore médio do teste monosyllable-trochee-polysyllable no primeiro mês, denominado MTP1, foi de 0,17 (0,08-0,33), no sexto mês com teste de 6 palavras, MTP6, foi de 0,72 (0,39-1,0), no sexto mês com 12 palavras, MTP12, foi de 0,46 (0,17-0,75) e no 12° mês com 12 palavras, MTP12, foi de 0,73 (0,25-1,0). Não houve correlação entre os valores do teste monosyllable-trochee-polysyllable em qualquer momento com o diâmetro do nervo coclear ipsilateral. Entretanto, o teste monosyllable-trochee-polysyllable do primeiro mês, do 6° mês, e o do 12° mês correlacionaram-se com a área transversal do nervo coclear ipsilateral. Conclusão Medir a área da secção transversal do nervo coclear de aparência normal pode fornecer conhecimento prognóstico importante sobre os resultados do implante coclear. Em pacientes com área da secção transversal maior, o desempenho auditivo foi melhor e mais rápido. Embora o nervo coclear pareça normal, pequenas diferenças na área da secção transversal do nervo coclear podem afetar o desempenho, de forma que a medida do tamanho do nervo coclear nas imagens de ressonância magnética na projeção parassagital pode fornecer informações benéficas sobre o processo de reabilitação pós-operatória.

Results of hyperbaric oxygen treatment in an at-risk nasal flap following trauma.

Hyperbaric oxygen treatment (HBOT) is widely used in otorhinolaryngology for various purposes. A 20-year-old male patient was admitted following a traumatic nasal wound which occurred several hours prior. He had a nasal glass cut from the radix to the supratip area which was primarily closed by non-absorbable suture. The following day, there was a haematoma and necrosis of the skin. The haematoma was drained under local anaesthesia. Blood supply to the nasal skin was severely compromised and only the columellar artery remaining intact, by definition designating this a difficult to heal wound with the risk of overall healing failure. Necrosis of the skin had developed within the first 24 hours. Accordingly, the patient underwent 30 HBOT sessions (two hours at 253.3 kPa) twice daily for four days and daily thereafter. Antibiotic cover and conservative wound management were also used. Complete healing was achieved without the need for additional surgical intervention. We conclude that timely use of HBOT may be a valuable adjunct to conservative wound management in a case of sharp nasal trauma.

Delayed presentation of head and neck cancer patients during COVID-19 pandemic.

PURPOSE: Impact of COVID-19 pandemic on healthcare is huge. We intended to demonstrate how COVID-19 pandemic affected primary head and neck oncology patient's referral and admission to a tertiary center by comparing the retrospective patient data in March-September 2020 and the same period in 2019. METHODS: In this cross-sectional study, from March 15th, 2020 to September 15th, 2020, medical records of 61 patients (Group 1) diagnosed and scheduled for surgery for head and neck cancer in our tertiary care center were revised and compared with 64 head and neck cancer patients treated in the same institution in the same time period of the previous year (Group2). Surgical site, TNM stages, need for reconstruction with flap, time from first symptom occurrence to first admission to our institution, and time to surgery were noted. RESULTS: In Group 1, out of 56 patients, 26 were diagnosed with T1-2 tumor, while 30 had T3-4 tumor. In Group 2, 43 of 60 patients had T1-2 tumor, while only 17 of them were diagnosed with T3-4 tumor. The rate of T3-4 tumors had significantly increased in 2020 when compared to 2019 (p = 0.049). In oral cavity cancer patients, N stage was significantly increased in Group 1 when compared to Group 2 (p = 0.024). Need for reconstruction with regional or free flaps were significantly increased in oral cavity cancer patients (p = 0,022). The mean time from the beginning of the first symptom to the admission was 19.01 ± 4.6 weeks (ranging between 11 and 32 weeks) in Group 1, while it was 16.6 ± 5.9 weeks in Group 2 (ranging between 6 and18 weeks); with significant increase (p = 0,02). The time to surgery from first admission was 3.4 ± 2.5 and 2.9 ± 1.2 weeks in Group 1 and 2, respectively, with no statistically significant difference (p = 0.06). CONCLUSION: The COVID-19 pandemic has caused delay in the diagnosis and treatment of many diseases as such in head and neck cancers. Admission with advanced stage disease and the need for more complex reconstructive procedures were increased. During the pandemic, the management of other diseases that cause mortality and morbidity should not be neglected and priorities should be determined.

Evaluation of Olfactory Function With Objective Tests in COVID-19-Positive Patients: A Cross-Sectional Study.

OBJECTIVE: Olfactory dysfunction is relatively high in coronavirus disease 2019 (COVID-19) patients. The aim of this study is to investigate the incidence of olfactory disorder objectively in patients with laboratory-confirmed COVID-19 infection. MATERIAL AND METHOD: The study included 31 healthy controls and 59 COVID-19 patients who were diagnosed and treated in the COVID departments in a tertiary hospital. The patients with corona virus infection were screened by a questionnaire and were classified into 2 groups as either group 2 (patients without self-reported smell loss) or group 3 (patients with self-reported smell loss). Age and gender matched healthy controls who do not have chronic nasal condition or nasal surgery history comprised the control group (group 1). All of the patients and subjects in the control group were tested by the Sniffin' Sticks test. All of the answers and scores were recorded, and the comparisons were made. RESULTS: The rate of self-reported smell and taste loss in all COVID-19 patients in this study was 52.5% and 42%, respectively. There was a significant difference in threshold, discrimination, identification, and Threshold, Discrimination, Identification (TDI) scores between groups 1 and 2. When the comparisons between group 1 and 3 were made, again threshold, discrimination, identification, and TDI scores were significantly different. The comparison between groups 2 and 3 demonstrated a significant difference in discrimination, identification, and TDI scores, but threshold score was not different statistically. With questionnaire, the rate of olfactory dysfunction in COVID-19 patients was 52.5%, but with objective test, the rate was calculated as 83%. CONCLUSION: Olfactory and gustatory dysfunctions are common in COVID-19 patients. According to findings with the objective test method in this study, smell disorder in COVID-19 patients was much higher than those detected by questionnaires.

Helicobacter pylori in allergic and non-allergic rhinitis does play a protective or causative role?

PURPOSE: Many studies have investigated the effect of Helicobacter pylori (H. pylori) colonization on the development of allergic diseases, but with conflicting results. The purpose of this cross-sectional observation study is to estimate H. pylori prevalence in allergic and nonallergic nasal conditions and compare with normal population. METHODS: 274 patients were tested for H. pylori with stool antigen test. Patients were compared with the control group for H. pylori positivity rates after they were categorized according to their primary diagnoses as mite allergy, pollen allergy, mite and pollen allergy, and non-allergic rhinitis with eosinophilic syndrome (NARES). Results were also classified according to age. RESULTS: The number of H. pylori-positive patients with mite allergy, mite and pollen allergy, and NARES were significantly higher than the control group in sadults. The percentages of patients in the pediatric group who had mite allergy, pollen allergy, mite and pollen allergy, or NARES were not significantly different when compared to the control group. CONCLUSION: Forthcoming studies would undoubtedly evaluate of the profits of treating allergic nasal conditions by treating the aforementioned bacterial infection.

Simultaneous idiopathic bilateral sudden hearing loss - characteristics and response to treatment / Perda auditiva súbita bilateral idiopática simultânea - características e resposta ao tratamento

Abstract Introduction The aetiology of sudden hearing loss is poorly defined; however, infectious, vascular and neoplastic aetiologies are presumed to be responsible. In addition, the aetiology of bilateral sudden hearing loss is also unknown. Objective The objective of this study is identify the characteristics and treatment response of simultaneous bilateral sudden hearing loss. Methods This is a case-control study that practised in tertiary care academic centre. 132 patients with sudden hearing loss who were treated with systemic steroid and hyperbaric oxygen together were included. 26 patients had bilateral sudden hearing loss and 106 patients had unilateral sudden hearing loss. Patients were evaluated with clinical, audiological and radiological examinations and laboratory tests were done. Findings and response to treatment of the patients were compared. Results The mean ages of patients with unilateral and bilateral sudden hearing loss were 42.0 years and 24.5 years respectively with a statistically significant difference (p < 0.001). Immune response markers were more prevalent in bilateral sudden hearing loss. Pre-treatment audiologic thresholds were 69.1 dB for unilateral sudden hearing loss and 63.3 dB for the left ears and 67.6 dB for the right ears for bilateral sudden hearing loss without significant difference. Post-treatment average hearing threshold in unilateral sudden hearing loss was 47.0 dB and 55.4 dB for the left ears and 59.0 for the right ears in bilateral sudden hearing loss. Average hearing improvement in unilateral sudden hearing loss group was significant (p < 0.001) in spite of it was not significant in bilateral sudden hearing loss group for both ears. Between the groups; there was a significant difference for hearing improvement favouring unilateral sudden hearing loss (p < 0.001). Tinnitus scores decreased significantly in both groups of patients (p < 0.001) in spite of there was no significant difference between the groups of patients. Conclusion Patients with bilateral sudden hearing loss showed lower age, worse prognosis and higher rate of positive immune response markers. Cardiovascular risk factors seem to have an important role in the aetiology of unilateral cases whereas this importance was not present in bilateral ones.

Resumo Introdução A etiologia da perda auditiva súbita ainda não está bem definida; contudo, presume-se que as etiologias infecciosas, vasculares e neoplásicas sejam as responsáveis. Além disso, a etiologia da perda auditiva súbita bilateral também é desconhecida. Objetivo O objetivo desse estudo foi identificar as características e a resposta ao tratamento de perda auditiva súbita bilateral simultânea. Método Este é um estudo de caso-controle realizado em um centro de atenção terciária. Foram incluídos 132 pacientes com Perda Auditiva Neurossensorial Súbita (PANS) que foram tratados com esteroides sistêmicos e oxigênio hiperbárico. 26 pacientes tiveram PANS bilateral e 106 pacientes tiveram PANS unilateral. Os pacientes foram avaliados com exames clínicos, audiológicos, radiológicos e exames laboratoriais. Os achados e a resposta ao tratamento dos pacientes foram comparados. Resultados As idades médias dos pacientes com PANS unilateral e bilateral foram 42,0 anos e 24,5 anos, respectivamente, com diferença estatisticamente significante (p < 0,001). Os marcadores de resposta imune foram mais prevalentes na PANS bilateral. Os limiares audiológicos pré-tratamento foram 69,1 dB para PANS unilateral e 63,3 dB para a orelha esquerda e 67,6 dB para a orelha direita para PANS bilateral, sem diferença significativa. O limiar médio de audição pós-tratamento em PANS unilateral foi de 47,0 dB e 55,4 dB para a orelha esquerda e 59,0 para a orelha direita em PANS bilateral. A melhora auditiva média no grupo com PANS unilateral foi significativa (p < 0,001), apesar de não ser significativa no grupo com PANS bilateral para ambas as orelhas. Houve diferença significativa entre os grupos na melhora auditiva favorecendo a PANS unilateral (p < 0,001). Os escores de zumbido diminuíram significativamente em ambos os grupos de pacientes (p < 0,001), apesar de não ter havido diferença significativa entre os grupos de pacientes. Conclusão Os pacientes com PANS bilateral eram mais jovens, tinham pior prognóstico e maior taxa de marcadores de resposta imunológica positiva. Os fatores de risco cardiovasculares parecem ter um papel importante na etiologia dos casos unilaterais, ao passo que essa importância não estava presente nos casos bilaterais.

Laryngotracheal reconstruction with a muscle-pedicle hyoid bone flap: a series of 23 patients.

We conducted a study to evaluate the effectiveness of muscle-pedicle hyoid bone flaps in the repair and reconstruction of the larynx and trachea in 23 patients who had undergone extended partial laryngectomy. Of this group, 17 patients had undergone surgery to correct laryngotracheal stenosis and 6 to remove laryngeal carcinoma. Intervention resulted in successful decannulation in 20 of the 23 patients (87.0%). Of the 3 patients who did not experience a successful outcome initially, 2 were successfully decannulated following a second intervention; the other patient required a total laryngectomy because of cancer recurrence. In light of our follow-up results, we conclude that hyoid bone appears to be an effective autograft in such cases.
