ABSTRACT
Abstract Introductıon: Deep neck infections are a group of diseases with serious complications and mortality, which can occur as a result of common diseases in the community and which have surgical and medical treatment options. Objectives: Patients ages, genders, complaints, physical examination findings, hospitalization complaints, history of antibiotic use before the application, additional diseases, radiological tests and analysis of examinations, type of treatment method, antibiotic agents selected in treatment, bacterial culture results, duration of hospitalization, complications, mortality rates were systematically recorded. In the study, anaerobic bacterial factors, which are difficult to produce in routine, were produced by considering special transport conditions and culture media. Methods: A total of 74 patients who were hospitalized in the Department of Otorhinolaryngology, University of Mersin, between 01.07.2016 and 01.07.2017 for deep neck infection were evaluated prospectively. The study included 37 female and 37 male patients. The ages of the patients ranged from 1 to 69 and the mean age was 31 years. Results: According to the analysis of the obtained data, there was a statistically significant relationship between the patients with additional diseases and the treatment modalities of the patients (p = 0.017). The surgical treatment rate was increased in this group of patients. In patients with a history of antibiotic use, it was found that patients in the pediatric group were in hospital longer in terms of length of stay compared to adults (p = 0.036). In adult patients who underwent surgery, the absorptive long axis was found to be longer in mm than in patients receiving isolated medical treatment (p = 0.008). Conclusions: Deep neck infections is a disease group that seriously concerns public health, with significant mortality and morbidity. Ensuring airway safety of patients should be the first intervention. Abscesses located lateral to the tonsil capsule may not drain adequately without concomitant tonsillectomy.
Resumo Introdução: As infecções cervicais profundas constituem um grupo de doenças com graves complicações e mortalidade, que podem ocorrer como resultado de doenças comuns na comunidade e que têm opções de tratamento médico e cirúrgico. Objetivo: Detectar bactérias anaeróbias e comparar a eficácia do tratamento médico-cirúrgico em diferentes faixas etárias. Método: Foram sistematicamente registrados idade dos pacientes, sexo, queixas, achados do exame físico, queixas na hospitalização, histórico de uso de antibióticos, doenças adicionais, exames radiológicos e análise dos exames, tipo de tratamento, agentes antibióticos selecionados no tratamento, resultados de cultura bacteriana, duração da hospitalização, complicações e taxas de mortalidade. No estudo, culturas bacterianas anaeróbias, difíceis de obter rotineiramente, mesmo considerando-se condições especiais de transporte e meios, foram obtidas. Foram avaliados prospectivamente 74 pacientes internados no Departamento de Otorrinolaringologia da Universidade de Mersin, entre 01.07.2016 e 07.07.2017, devido a infecção cervical profunda. O estudo incluiu 37 pacientes do sexo feminino e 37 do masculino. A idade dos pacientes variou de 1 a 69 anos e a média foi de 31. Resultados: De acordo com a análise dos dados obtidos, houve uma relação estatisticamente significante entre os pacientes com doenças adicionais e as modalidades de tratamento dos pacientes (p = 0,017). A taxa de tratamento cirúrgico foi maior nesse grupo de pacientes. Em pacientes com histórico de uso de antibióticos, verificou-se que aqueles do grupo pediátrico permaneceram mais tempo hospitalizados em comparação aos adultos (p = 0,036). Nos pacientes adultos submetidos à cirurgia, verificou-se que o eixo longo absortivo era mais longo em mm do que nos pacientes que receberam tratamento médico isolado (p = 0,008). Conclusão: As infecções cervicais profundas constituem um grupo de doenças que são preocupantes na saúde pública, com sua mortalidade e morbidade. Garantir a segurança das vias aéreas dos pacientes deve ser a primeira intervenção. Os abscessos localizados lateralmente à cápsula tonsilar podem não apresentar drenagem sem a tonsilectomia.
ABSTRACT
Abstract Introduction There has been a sudden idiopathic hearing loss case presented after methylphenidate treatment in a child with attention deficit hyperactivity disorder (ADHD). Objective This study was performed to reveal the probable ototoxic side effects of methylphenidate use in patients with ADHD. Methods Thirty pediatric patients with ADHD were included in the study. Pure tone audiometry, speech discrimination scores, waves I, III, V absolute latencies and waves IIII, I-V, III-V interpeak latencies at the 80 dB nHL intensity after click stimulus auditory brainstem response (ABR) results were compared before and 3 months after methylphenidate treatment. Results There were no statistically significant difference between pretreatment and posttreatment pure tone and speech audiometry findings and ABR results (p > 0.05 for all parameters). Conclusion Methylphenidate can be regarded as a safe drug regarding ototoxic side effects. Additional studies with a larger sample size and longer follow-up may be needed.

Abstract Introduction: Salivary gland tumors (SGTs) are rare head and neck malignancies consisting of a spectrum of tumors with different biological behaviors. Objective: In this study we aimed to find out differential expression of microRNA profiles between benign and malignant SGTs. Methods: We investigated the possible role of 95 microRNAs in the 20 patients with salivary gland tumors with comparison of 17 patients without malignancy or salivary gland diseases. Sixteen of the tumors were benign (seven pleomorphic adenomas, nine Warthin tumors), four of them were malignant (two squamous cell carcinomas, one high grade mucoepidermoid carcinoma, one adenocarcinoma). Serum and saliva samples were collected from both patients and control group. Tissue samples of tumor masses were also collected from patient group. Results: Among studied microRNAs miR-21, miR-23a, miR-27a, miR-223, miR-125b, miR-126, miR-146a, miR-30e were down regulated in the benign group compared to control group in the serum samples (p-values are 0.04, 0.00005, 0.00005, 0.0022, 0.031, 0.00008, 0.044, and 0.0007, respectively). When tissue samples were studied miR-21, miR-31, miR-199a-5p, miR-146b, miR-345 were up-regulated in the malignant group compared to benign group (p values are 0.006, 0.02, 0.013, 0.013, 0.041, respectively). miR-30e showed statistically significant up-regulation in malignant tumor group's plasma samples compared to benign group (p = 0.034). There was no statistically significant difference in saliva samples between groups. Conclusion: Our results showed that different microRNAs may play role in salivary tumor pathogenesis according to biological behavior. Although there was no difference in saliva samples between groups, according to tissue and serum samples miR-21 and 30e may have an important role; since they were down-regulated in benign tumors whereas up-regulated in malignant ones.
Resumo Introdução: Os tumores da glândula salivar (TGS) são lesões malignas raras de cabeça e pescoçoque consistem em um espectro de tumores com diferentes comportamentos biológicos. Objetivo: Neste estudo, tivemos como objetivo identificar a expressão diferencial de perfis demicroRNA entre TGS benignos e malignos. Método: Investigamos a possível participação de 95 microRNA em 20 pacientes com tumoresde glândulas salivares comparados com 17 pacientes sem doença maligna ou doenças das glân-dulas salivares; 16 dos tumores eram benignos (sete adenomas pleomórficos, nove tumores deWarthin), quatro eram malignos (dois carcinomas espinocelulares, carcinoma mucoepidermoidede alto grau, um adenocarcinoma). As amostras de soro e saliva foram coletadas de pacien-tes e do grupo controle. Amostras de tecido dos tumores também foram colhidas do grupo depacientes com tumores. Resultados: Entre os microRNA estudados, miR-21, miR-23a, miR-27a, miR-223, miR-125b, miR-126, miR-146a, miR-30e foram infrarregulados no grupo benigno em comparação com o grupocontrole nas amostras do soro (os valores de p são 0,04, 0,00005, 0,00005, 0,0022, 0,031,0,00008, 0,044 e 0,0007, respectivamente). Quando as amostras de tecido foram estudadas,miR-21, o miR-31, o miR-199-5p, miR-146b, o miR-345 foram suprarregulados no grupo malignoem relação ao grupo benigno (valores de p são 0,006, 0,02, 0,013, 0,013, 0,041, respectiva-mente). O miR-30e apresentou suprarregulação estatisticamente significativa em amostras deplasma do grupo de tumor maligno em relação ao grupo benigno (p = 0,034). Não houve diferençaestatisticamente significativa em amostras de saliva entre os grupos. Conclusão: Nossos resultados mostraram que diferentes microRNA podem desempenhar umpapel na patogenia do tumor salivar de acordo com o comportamento biológico. Embora nãotenha havido diferença em amostras de saliva entre os grupos, de acordo com as amostras detecido e de soro, miR-21 e 30e podem ter um papel importante, já que foram infrarreguladosnos tumores benignos enquanto suprarregulados nos tumores malignos.

Introduction Auditory neuropathy/dyssynchrony (AN/AD) comprises a spectrum of pathology affecting the auditory pathways anywhere from the inner hair cells to the brainstem. It is characterized by an absent or atypical auditory brainstem response (ABR) with preservation of the cochlear microphonics and/or otoacoustic emissions (OAEs). Objective Retrospective analysis of patients with AN/AD. Methods Fifteen patients with AN/AD were included in this study and their records were retrospectively investigated. Results Possible etiology of AN/AD was neonatal hyperbilirubinemia in three patients, family history of hearing loss in three patients, consanguineous marriage in two patients, head trauma in two patients, mental motor retardation in one patient, cerebrovascular disease in one patient, and there was no apparent cause in three patients. Conclusion Otolaryngologists should keep in mind the diagnosis of AN/AD especially in patients complaining of difficulty in hearing and speech and audiological evidence of disassociation between pure tone and speech audiometry. ABR and OAE testing is recommended in these patients for AN/AD diagnosis. .
