Título: Molecular identification of viral agents associated with acute conjunctivitis: a prospective controlled study
Fonte: Braz. j. infect. dis;21(4):391-395, July-Aug. 2017. tab.
Idioma: en.
Resumo: Abstract Background: Viral conjunctivitis are the most frequent infections in ophthalmology clinics. The diagnosis is usually relying on clinical findings and medical history. However, topical antibiotics are often used unnecessarily addition to symptomatic treatment because of unsure agents. We aimed to detect the Adenovirus, Coxsackievirus and Enterovirus from conjunctiva and pharyngeal samples of patients. Methods: The conjunctiva and pharyngeal samples of the patients with conjunctivitis were taken by Virocult transport media and kept at -80 ºC up to study day. Adenovirus spp, Enterovirus 70 and Enterovirus 71, Coxsackie A24 and Coxsackie A16 were detected by real-time PCR. Samples from healthy health care workers of ophthalmology clinic were used for control group. Results: A total of 176 samples (conjunctival and pharyngeal samples of 62 patient and 26 healthy subjects) were included. The mean age of 34 (55.7%) male and 27 (44.3%) female patients was 34 ± 17. Twenty five (40.3%) of the patients were receiving antibiotic drops at first visit. The main etiologic agent in conjunctival samples was found to be Adenovirus (46/62, 74.2%) followed by Enterovirus 70 (4/62, 6.4%) and Enterovirus 71 (4/62, 6.4%). Coxsackievirus 16 and 24 were also found in 2 patients (1/62 each, 1.6%). Pharyngeal samples were also positive for Adenovirus (20/62, 32.3%), Enterovirus 70 and 71 (7/62, 11.3% and 5/62, 8.1% respectively), Coxsackievirus 16 and 24 (2/62, 3.2% and 1/61, 1.6%). Conclusions: It is very difficult in viral conjunctivitis to make clinical differentiation caused by different agents because of common clinical signs and symptoms. In routine clinical work, the viral conjunctivitis usually related with Adenovirus. But almost one fourth of the patients' conjunctivitis were not related to Adenovirus, which shows the importance of the laboratory diagnostics. True diagnosis plays an important role on prevention of contamination and unnecessary use of antibiotics in viral conjunctivitis.

Idioma: en.
Resumo: ABSTRACT Meningococcal carriage is a prerequisite for invasive infection. This cross-sectional study assessed the pharyngeal carriage prevalence in healthy subjects aged 1-24 years in Embu das Artes city, São Paulo, Brazil. Pharyngeal swabs were examined for the presence of Neisseria meningitidis. The isolates were tested for different serogroups using agglutination and polymerase chain reaction. A logistic regression model assessed any independent association between Neisseria meningitidis carriage and various risk factors. A total of 87/967 subjects (9%, 95% Confidence Interval (CI): 7.3-11.0) tested positive for N. meningitidis: 6.2% (95% CI: 3.8-9.4) in 1-4 years, 8.5% (95% CI: 5.1-13.0) in 5-9 years, 12.5% (95% CI: 7.8-18.6) in 10-14 years, 12.6% (95% CI: 7.4-19.7) in 15-19 years and 9% (95% CI: 4.9-14.9) in 20-24 years age groups. Highest carriage prevalence was observed in adolescents 10-19 years old. Serogroup C was predominant (18.4%) followed by serogroup B (12.6%). The 15-19 years age group showed a significant association between number of household members and carriers of N. meningitidis. This cross-sectional study is the first in Brazil to evaluate meningococcal carriage prevalence and associated factors in a wide age range.

Resumo: The aim of this study was to describe the first occurrence ofKudoasp. inGobioides grahamae, contributing to the understanding of this group of parasites in the Amazonian ichthyofauna. Forty specimens ofG. grahamaecollected from the natural environment were analyzed. Cysts ofKudoasp. were diffusely distributed through the striated skeletal muscle fibers with severe edema and inflammatory infiltrate composed of lymphocytes were observed in 30% of the specimens. Edema and marked coagulation necrosis of the muscle fibers was associated with infection byKudoasp. spores, which had accumulated inside the skeletal muscle fibers. Although there are no records of foodborne outbreaks caused by Kudoa spp. in Brazil, it is of paramount importance that we evaluate its occurrence, since the consumption of fish, especially raw fish, has increased because of the adoption of Japanese cuisine. To minimize the economic impacts on the fisheries market and the risk of this parasite to public health, it is necessary to initiate a program to monitor the presence of this likely underdiagnosed, emerging parasite.(AU)

O objetivo deste estudo foi descrever a primeira ocorrência de Kudoa sp. em Gobioides grahamae, contribuindo, assim, para a compreensão desse grupo de parasitas na ictiofauna amazônica. Foram analisados 40 espécimes de G. grahamae coletados de ambiente natural. Cistos de Kudoa sp. foram distribuídos difusamente através das fibras musculares esqueléticas estriadas com presença de edema grave e infiltrado inflamatório composto de linfócitos, que foram observados em 30% dos espécimes. Edema e necrose de coagulação acentuada das fibras musculares foram associados com a infecção por esporos de Kudoa sp., acumulados no interior das fibras musculares da faringe. Apesar de não haver registros de surtos de origem alimentar causada por Kudoa spp. no Brasil, é de suma importância a avaliação de sua ocorrência, uma vez que o consumo de peixe, especialmente peixe cru, aumentou por causa da adoção da culinária japonesa. Para minimizar os impactos econômicos no mercado da pesca e o risco desse parasita para a saúde pública, é necessário iniciar um programa para monitorar a presença desse parasita emergente, possivelmente subdiagnosticada.(AU)

Título: Condroma del espacio parafaríngeo, reporte de un caso / Chondroma of the parapharyngeal space, report of one case
Fonte: Rev. colomb. cir;33(2):206-210, 2018. tab, fig.
Idioma: es.
Resumo: Introducción. El condroma es una neoplasia benigna de origen mesenquimal y de etiología desconocida, muy infrecuente en los tejidos blandos debido a su constitución de células de cartílago maduro sin hueso; sin embargo, son frecuentes las calcificaciones focales. Al presentarse en cabeza y cuello, suele hacerlo en el maxilar o el paladar duro, y son pocos los reportes de este tumor en el espacio parafaríngeo. Se reporta el caso de una paciente de 68 años de edad, que acudió a consulta por dolor en el paladar blando, cefalea y dolor paratiroideo izquierdo asociado a disfagia de cuatro años de evolución. Se practicaron los estudios pertinentes y, finalmente, se confirmó el diagnóstico de condroma mediante biopsia. Discusión. Los condromas muy rara vez se encuentran en los tejidos blandos, por lo cual se sugiere que el diagnóstico sea cuidadosamente orientado para descartar una posible malignidad de la lesión y que los controles posquirúrgicos sean frecuentes

Introduction: Chondroma is a benign neoplasm of mesenchymal origin and of unknown etiology, very infrequently appearing in the soft tissues due to its constitution of mature cartilage cells without bone; however, they usually present focal calcifications. When occurring in the head and neck, they usually appear in the jaw or hard palate. Just a few cases of this pathology are reported in the pharynx. Materials and Methods: We present a case of a female 68 years old, who came to the clinic due to pain in the soft palate, headache and left parathyroid pain associated with dysphagia, of four years of evolution. Corresponding studies were carried out and finally the diagnosis of chondroma was confirmed by biopsy. Discusion: Chondromas are rarely found in the soft tissues, suggesting that the diagnosis should be carefully oriented to rule out possible malignancy of the lesion and that post-surgical controls should be frequent

Idioma: es.
Resumo: INTRODUCCIÓN: La planificación de cirugías para el manejo del síndrome de apneahipopnea obstructiva del sueño (SAHOS) ha incrementado su precisión desde la introducción de la endoscopía del sueño inducido por fármacos (DISE). OBJETIVO: Evaluar la técnica de faringoplastía de reposición con suturas barbadas (BRP) para el colapso velofaríngeo y/o de paredes laterales orofaríngeas evaluado mediante DISE en pacientes con SAHOS. MATERIAL Y MÉTODO: Ochenta y ocho pacientes fueron evaluados para cirugía mediante antropometría, escala de somnolencia de Epworth (ESS) y poligrafía respiratoria. Veinte y seis de 88 pacientes fueron seleccionados. De los 26, 14 accedieron al tratamiento quirúrgico, el que se seleccionó en base a la DISE. En todos los casos, se realizó BRP. RESULTADOS: A los 3 meses de la cirugía hubo mejoría en 10/14 pacientes (criterios de Sher, disminución del índice de apnea-hipoapnea a <20 o 50% del basal). La ESS bajó en promedio de 12 a 5 puntos (p <0,05). No se reportaron incidentes en el posoperatorio y no han ocurrido eventos adversos. CONCLUSIÓN: La técnica de BRP es una técnica sencilla y útil para la expansión anterior y lateral del paladar blando y orofaringe, con una tasa de éxito similar en esta cohorte a la reportada internacionalmente.

INTRODUCTION: Surgical planning for the management of obstructive sleep apneahypopnea syndrome (OSAHS) has changed since the introduction of drug induced sleep endoscopy (DISE). AIM: To evaluate the technique of barbed sutures reposition pharyngoplasty (BRP) for velopharyngeal collapse and/or oropharyngeal lateral walls after DISE evaluation in OSAHS patients. MATERIAL AND METHOD: 88 patients were evaluated for surgery by anthropometry, Epworth sleepiness scale (ESS) and respiratory polygraphy. 26 of 88 patients were selected. Of the 26, 14 agreed to surgical treatment, which was selected on DISE findings. In all cases, BRP was performed. RESULTS: Three months after surgery there was improvement in 10/14 patients (Sher criteria, apnea-hypopnea index reduction at <20 or 50% of baseline). The ESS improved on average 12 to 5 (p <0.05). No incidents were reported in the post-operative period and no adverse events were reported. CONCLUSION: The BRP technique is a simple and useful technique for the anterior and lateral expansion of the soft palate and oropharynx, with a similar success rate in this cohort to that internationally reported.

Título: Clinical outcome of sodium alginate therapy in radiation-induced pharyngeal mucositis: experience of a single Japanese institution
Fonte: Appl. cancer res;39:1-5, 2019. ilus, tab.
Idioma: en.
Resumo: Purpose: We investigated the clinical outcome of sodium alginate treatment in radiation-induced pharyngeal mucositis (RIPM) after neck irradiation. Materials and methods: The study population included 32 patients (11 lung cancer, 10 breast cancer, 7 head and neck cancer, and 4 other primary lesions) who underwent neck external beam radiotherapy at the authors' institution between June 2006 and 2016. The patients received 5% sodium alginate solution orally for RIPM. Those who were followed up for less than 2 months or did not receive 5% sodium alginate were excluded from this retrospective study. RIPM was graded weekly as an acute toxicity according to the Common Terminology Criteria for Adverse Events (CTCAE), version 4. The administration of 10-15 ml of sodium alginate before each meal was continued until the radiotherapy was completed and after resolution of odynophagia. The efficacy of sodium alginate was assessed by two radiation oncologists as follows: Grade I, ineffective; grade II, moderately effective; grade III, very effective. When sodium alginate was ineffective, other analgesics, such as nonsteroidal antiinflammatory drugs (NSAIDS) or opioids, were added. Relationships between the presence/absence of additional analgesics and the radiation dose were investigated. Results: The median duration from the start of irradiation to sodium alginate administration was 15 days (range, 5­36 days). RIPM improved in 29/32 patients (grade: II, n = 22; III, n = 7). Three patients showed no improvement. No sodium alginate-related toxicities occurred. Additional analgesics were required in 5/32 patients. The radiation dose in these 5 patients was significantly higher than that in the sodium alginate-alone group (63.6 ± 7.8 Gy vs 48.3 ± 14.8Gy, P = 0.02). Patients who received > 50 Gy tended to require additional analgesics more frequently than those who received ≤50Gy (P = 0.10). Conclusions: The concurrent administration of sodium alginate and neck irradiation was feasible and tolerable without obvious toxicities. Under certain conditions sodium alginate could be a promising alternative to NSAIDs and opioids in RIPM. The results justify further prospective evaluations with detailed treatment protocols to clarify whether sodium alginate can improve RIPM (AU)

Título: Lateral-Expansion Pharyngoplasty: Combined Technique for the Treatment of Obstructive Sleep Apnea Syndrome
Fonte: Int. arch. otorhinolaryngol. (Impr.);24(1):107-111, Jan.-Mar. 2020. tab, graf.
Idioma: en.
Resumo: Abstract Introduction Obstructive sleep apnea syndrome (OSAS) is a multifactorial disease characterized by episodes of partial or complete collapse during sleep of different regions of the upper airway. Surgery for OSAS evolved with the introduction of different techniques, considering new surgical concept of reconstruction of the upper airway. Objective To retrospectively evaluate the effectiveness of a new approach aimed at reducing pharyngeal collapse by combining two surgical techniques: lateral and expansion pharyngoplasty. Methods We reviewed the medical records of 38 patients with OSAS undergoing lateral/expansion pharyngoplasty from January 2012 to December 2016. The following data were collected: patient age, gender, and pre- and postoperative body mass index (BMI), Epworth sleepiness scale (ESS) scores, snoring visual analogue scale (VAS) scores, and polysomnography (PSG) results. Results The PSG results showed a significant reduction in the apnea/hypopnea index (AHI) from 22.4 ± 27.3 events/h preoperatively to 13.6 ± 17.9 events/h postoperatively (p = 0.009), with postoperative AHI reduction greater than 50% in 63.2% of the patients. There was also a significant reduction in the microarousal index (19.5 ± 22.6 vs 11.0 ± 13.4 events/h; p = 0.001) and in the minimum oxygen saturation (82.6 ± 10.3 vs 86.9 ± 11.1; p = 0.007). Conclusions Lateral-expansion pharyngoplasty represents a new surgical strategy for the treatment of OSAS in patients with palatal collapse by combining two different techniques: lateral and expansion pharyngoplasty. The two techniques, performed as a one-stage procedure, led to improvements in excessive daytime sleepiness, snoring, and PSG respiratory parameters by acting on lateral and retropalatal collapse, produc- ing favorable results with good applicability in otolaryngology clinical practice.

Idioma: en.
Resumo: The aim of this investigation was to define the volume and area of the airway in subjects with Class II and Class III skeletal deformity. A cross-sectional study was designed including subjects with facial deformity defined by Steiner's analysis in subjects with indication of orthognathic surgery who presented diagnosis by cone beam computerised tomography. We determined the measurements of maximum area, minimum area and volume of the airway. The data were compared using Spearman's test, with statistical significance defined as p<0.05. 115 subjects were included: 61.7 % Class II and 38.3 % Class III, mean age 27.8 years (± 11.6). A significant difference was observed in the area and volume measurements in the groups studied, with significantly smaller measurements found in Class II (p=0.034). The minimum area was 10.4 mm2 smaller in Class II patients than in Class III, while the general volume of the airway was 4.1 mm3 smaller in Class II than in Class III. We may conclude that Class II subjects present a smaller airway volume than Class III subjects.

El objetivo de esta investigación de definir el volumen y área de vía aérea en sujetos con deformidad esqueletal clase II y III. Se diseñó un estudio de corte transversal incluyendo sujetos con deformidad facial definida según análisis de Stainer en sujetos con indicación de cirugía ortognática que presentaran una tomografía computadorizada de haz cónico como elemento diagnóstico; en este examen se determinaron medidas de área mayor, menor de vía aérea y volumen presente; los datos fueron comparados utilizando pruebas estadísticas con el test de spearman considerando el valor de p<0,05 para definir significancia estadística. 115 sujetos fueron incluidos, siendo 61,7 % de tipo clase II y 38,3 % de sujetos clase III, con una edad promedio de 27,8 años (± 11,6). Se observó una diferencia significativa en mediciones de area y volumen en los grupos estudiados, siendo el grupo de clase II significativamente menor (p=0,034). El área de menor tamaño fue 10,4 mm2 en pacientes clase II que en pacientes clase III, mientras que el volumen general de la vía área fue 4,1 menor en los clase II que en los clase III. Es posible concluir que los sujetos de clase II presentan menor volumen de vía área que los sujetos clase III.
