Mantle Cell Lymphona Masquerading as Obstructive Sleep Apnoea

@#Tonsillar malignancy typically presents with asymmetrical tonsillar enlargement, lesion on the tonsils, sore throat or a neck mass. We report a case of unsuspected tonsillar malignancy in a 56-year-old gentleman who presented with symptoms of obstructive sleep apnoea. His tonsils were grade III bilaterally with normal mucosa. Tonsillectomy was performed to improve patient’s compliance with Continuous Positive Airway Pressure (CPAP) therapy. These tonsillar specimens were reported to be Mantle Cell Lymphoma (MCL) based on the histology and ancillary studies. This case highlights that benign-looking symmetrical tonsillar enlargement can harbour occult malignancy. It is important to note that OSA symptoms may be the presentation for haematological malignancies. Tonsillar specimens should be sent for histopathological examination regardless of the indication to avoid misdiagnosis and delay in treatment.

Pólipos linfangiomatosos de las amígdalas palatinas en la infancia: Reporte de un caso y revisión / Lymphangiomatous polyps of the palatine tonsils in childhood: A case report and review

Introducción: Los pólipos linfangiomatosos de las amígdalas palatinas son lesiones benignas raras. Esta entidad se origina en el estroma linfoide mezclándose con el parénquima, siendo diferente a la hiperplasia papilar y representa aproximadamente el 1,9% de las neoplasias de amígdalas.

Amígdalas y adenoides: defensa ante agentes patógenos y su implicancia estomatológica / Tonsils and adenoids: defend to pathogenic agents and their stomatological involvement

La función de las amígdalas siempre ha sido discutida, desde afirmar que no tenían funcionalidad, hasta la actualidad que se plantea un papel inmunológico, con actividad linfocitaria de defensa, debido a la localización de linfocitos en el tejido de las amígdalas. Este artículo de actualización pretende describir desde la embriología, histología, fisiología, patología y estomatología, el rol que desempeñan las mismas en su papel inmunológico ante la acción de agentes patógenos. Se destaca la acción conjunta de las amígdalas palatinas, amígdalas faríngeas o adenoides, amígdalas peritubarias, amígdalas linguales y todo el resto de tejido linfático que conforman el anillo linfático faríngeo o anillo de Waldeyer, ya que cumplen un rol determinante en la defensa del organismo (AU)

The function of the tonsils has always been debated, from stating that they had no functionality, to the present day that an immunological role is proposed, with lymphocyte defense activity, due to the location of lymphocytes in the tissue of the tonsils. This update article aims to describe from embryology, histology, physiology, pathology and stomatology, the role they play in their immunological role against the action of pathogens. The joint action of the palatine tonsils, pharyngeal or adenoid tonsils, peritubal tonsils, lingual tonsils and all the rest of the lymphatic tissue that make up the pharyngeal lymphatic ring or Waldeyer's ring is highlighted, since they play a decisive role in the defense of the organism (AU)

Influence of the palatine tonsil grade on the morphology of the maxillary and mandibular dental arches / Influencia del grado de las tonsilas palatinas en la morfología de los arcos dentales maxilar y mandibular

SUMMARY: Enlarged palatine tonsils and adenoids are thought to cause obstruction of the upper airway, triggering changes in breathing patterns, which in turn lead to dentofacial alterations, including malocclusions. The object of the present study was to correlate the size (grade) of the palatine tonsil with measurements of the maxillary and mandibular dental arches in children. This was an observational cross-sectional study carried out in 35 children aged between 6 and 11 years. The inter- and intra-arch parameters were measured (horizontal, vertical and sagittal analyses) by making plastercasts and then taking measurements with callipers. The tonsil size was classified in 5 grades from 0-4, using the Brodsky tonsil grading scale. The researcher was calibrated prior to carrying out the measurements. Pearson's chi-squared test was used and Pearson's correlation coefficient was calculated. The SPSS v.22.0 software was used, with a significance threshold of 5 %. Six patients were classified as grade 1, sixteen grade 2, eleven grade 3, two grade 4 and none of the patients presented grade 0.A low positive association was found between tonsil grade and the total length of the mandibular arch, a very low positive association between tonsil grade and maxillary inter-first premolar distance, total length of the maxillary arch and depth of the palatine recess.A very low negative association was found for tonsil grade and overjet, overbite, mandibular inter-permanent first molar distance, mandibular inter-first premolar distance, and mandibular and maxillary intercanine widths. No statistically significant correlation was observed for any of the measurements. No association was found between the tonsil grade and Angle's Classification, canine relationship, overjet and overbite. According to the results of this study there is no significant correlation between the dental arches and the tonsil grade.

RESUMEN: Se ha considerado que el grado del tamaño de las tonsilas palatinas y los adenoides pueden ser factores que generan obstrucción de la vía aérea superior, desencadenando cambios en el patrón de respiración, lo que provoca alteraciones dentofaciales, entre ellas, maloclusiones. El objetivo del presente estudio fue correlacionar el grado tonsilar palatino con medidas de los arcos dentales maxilar y mandibular en niños. Se realizó un estudio observacional de corte transversal. Fueron incluidos 35 niños entre 6 y 11 años de edad. Fueron medidos parámetros interarco e intra-arco (análisis transversal, vertical, sagital). Para eso fueron tomados modelos de yeso y luego las medidas fueron realizadas con un caliper. El grado tonsilar fue clasificado en 5 grados (0-5), de acuerdo a la escala de graduación de Brodsky. Para la realización de las mediciones el evaluador fue previamente calibrado. Se realizó la prueba Chi-cuadrado de Pearson, y coefi- ciente de correlación de Pearson. Se utilizó el software SPSS 22.0, considerándose umbral de significación de 5 %. Seis pacientes fueron clasificados en grado 1, dieciséis grado 2, once grado 3, dos grado 4 y ningún paciente presentó grado 0. Se encontró una asociación positiva baja entre grado tonsilar y la longitud total del arco mandibular, positiva muy baja entre grado tonsilar y distancia inter-primer premolar maxilar, longitud total del arco maxilar y profundidad de la bóveda palatina. Una asociación negativa muy baja fue encontrada para el grado tonsilar y overjet, overbite, distancia inter-primer molar permanente mandibular, distancia inter- primer premolar mandibular, ancho intercanino mandibular y maxilar. Se observó ausencia de correlación estadísticamente significativa para todas las medidas. No se encontró asociación entre el grado tonsilar y clase molar de Angle, relación canina, overjet y overbite. Según los resultados de este estudio no se aprecia una correlación significativa entre los arcos dentales y el grado tonsilar.

Optimization of Microenvironments Inducing Differentiation of Tonsil-Derived Mesenchymal Stem Cells into Endothelial Cell-Like Cells

BACKGROUND: Stem cell engineering is appealing consideration for regenerating damaged endothelial cells (ECs) because stem cells can differentiate into EC-like cells. In this study, we demonstrate that tonsil-derived mesenchymal stem cells (TMSCs) can differentiate into EC-like cells under optimal physiochemical microenvironments.METHODS: TMSCs were preconditioned with Dulbecco's Modified Eagle Medium (DMEM) or EC growth medium (EGM) for 4 days and then replating them on Matrigel to observe the formation of a capillary-like network under light microscope. Microarray, quantitative real time polymerase chain reaction, Western blotting and immunofluorescence analyses were used to evaluate the expression of gene and protein of EC-related markers.RESULTS: Preconditioning TMSCs in EGM for 4 days and then replating them on Matrigel induced the formation of a capillary-like network in 3 h, but TMSCs preconditioned with DMEM did not form such a network. Genome analyses confirmed that EGM preconditioning significantly affected the expression of genes related to angiogenesis, blood vessel morphogenesis and development, and vascular development. Western blot analyses revealed that EGM preconditioning with gelatin coating induced the expression of endothelial nitric oxide synthase (eNOS), a mature EC-specific marker, as well as phosphorylated Akt at serine 473, a signaling molecule related to eNOS activation. Gelatin-coating during EGM preconditioning further enhanced the stability of the capillary-like network, and also resulted in the network more closely resembled to those observed in human umbilical vein endothelial cells.CONCLUSION: This study suggests that under specific conditions, i.e., EGM preconditioning with gelatin coating for 4 days followed by Matrigel, TMSCs could be a source of generating endothelial cells for treating vascular dysfunction.

Marek's disease vaccine activates chicken macrophages

To provide insights into the role of innate immune responses in vaccine-mediated protection, we investigated the effect of Marek's disease (MD) vaccine, CVI988/Rispens, on the expression patterns of selected genes associated with activation of macrophages in MD-resistant and MD-susceptible chicken lines. Upregulation of interferon γ, interleukin (IL)-1β, IL-8, and IL-12 at different days post-inoculation (dpi) revealed activation of macrophages in both chicken lines. A strong immune response was induced in cecal tonsils of the susceptible line at 5 dpi. The highest transcriptional activities were observed in spleen tissues of the resistant line at 3 dpi. No increase in the population of CD3³ T cells was observed in duodenum of vaccinated birds at 5 dpi indicating a lack of involvement of the adaptive immune system in the transcriptional profiling of the tested genes. There was, however, an increase in the number of macrophages in the duodenum of vaccinated birds. The CVI988/Rispens antigen was detected in the duodenum and cecal tonsils of the susceptible line at 5 dpi but not in the resistant line. This study sheds light on the role of macrophages in vaccine-mediated protection against MD and on the possible development of new recombinant vaccines with enhanced innate immune system activation properties.

Hipertrofia de amígdala lingual y apnea obstructiva del sueño en población pediátrica: una asociación a considerar / Hypertrophy of the Lingual Tonsils and pediatric obstructive sleep apnea syndrome: an assocciation to consider

Las amígdalas linguales (AL) forman parte del Anillo de Waldeyer (AW). La hipertrofia de amígdala lingual (HAL) se debe habitualmente a hiperplasia, generalmente asintomática. Su etiología no está precisada, pero se reconoce como causa de Apnea Obstructiva del Sueño (AOS) residual, posterior a adenoamigdalectomía (AA). Su identificación en el examen físico es dificultosa, por lo que resulta relevante la sospecha, junto con una nasofibroscopía. Según condiciones y sintomatología del paciente se puede complementar el estudio con otras técnicas diagnósticas, como polisomnograma (PSG) y resonancia magnética (RM). La cirugía es exitosa para el tratamiento de estos casos. Dentro de las complicaciones descritas para este procedimiento destacan: hemorragia, obstrucción de la vía área, dificultad en la intubación orotraqueal y dolor en el posoperatorio. Actualmente no existe una técnica quirúrgica de elección. Debido a la morbilidad asociada a AOS resulta fundamental el diagnóstico de esta patología, ya que es susceptible de tratamiento.

Lingual tonsils are part of Waldeyer`s Ring. The hypertrophy of the lingual tonsils is generally due to hiperplasia, without symptoms. The etiology is not clear, but it is a known cause of residual Obstructive Sleep Apnea (OSA), after adenotonsilectomy. Their identification during the physical exam results dificult, so the suspicious and the nasofibroscopy are relevant. Acording to the particular patient it is posible realize additional exams, like polisomnography and magnetic nuclear resonance. Surgery is succesful for this cases. The complications include: bleeding, airway obstruction, anestesia dificulties and pain. Currently there is not a particular techniqe of choice. OSA is associated to morbidity, therefore it is fundamental to diagnose this pathology, because it is posible to treat it through surgery.

Epidermoid Cyst of The Tonsil: A Rare Finding

Epidermoid cysts are benign developmental cyst with a low incidence in the head and neck region of approximately 2%.  The various locations where the cyst can arise are sublingual, submental, submandibular, buccal mucosa and very rarely the tonsils. Here we present an epidermoid cyst of left tonsil which was incidentally detected in a patient diagnosed of chronic tonsilitis.

Adult tonsillectomy: postoperative pain depends on indications / Tonsilectomia no adulto: a dor pós-operatória depende das indicações

ABSTRACT INTRODUCTION: Intense pain is one of the most important postoperative complaints after tonsillectomy. It is often described by patients as comparable to the pain that accompanies an acute tonsillitis. Although recurrent tonsillitis is the most frequent indication for surgery, many tonsillectomies are performed due to other indications and these patients may be unfamiliar with such pain. OBJECTIVE: To verify whether individuals with recurrent tonsillitis experience different post-tonsillectomy pain intensity than those with other indications for surgery, with no history of episodes of acute tonsillitis. METHODS: A total of 61 tonsillectomies were performed under general anesthesia, using a potassium titanyl phosphate (KTP) laser (to eliminate the potential influence on the study results of forceful dissection of fibrotic tonsils in patients with history of recurrent tonsillitis) and multiple ligations of blood vessels within the tonsillar beds. The patients received 37.5 mg Tramadoli hydrochloridum + 325 mg Paracetamol tablets for 10 days. Postoperative variables included the duration of hospital stay, postoperative hemorrhage and readmission rate. The patients reported pain intensity on consecutive days, pain duration, weight loss on postoperative day 10, character, intensity and duration of swallowing difficulties, and the need for additional doses of painkillers. Healing was also assessed. Capsular nerve fibers were histologically examined in the resected tonsils by immunostainings for general and sensory markers. RESULTS: Indications for the surgery were: recurrent acute tonsillitis (34 patients), no history of recurrent tonsillitis: focus tonsil (20) and intense malodour (7). Pain intensity on postoperative days 3-4 and incidence of readmissions due to dehydration were significantly higher in the group with no history of recurrent tonsillitis. No significant differences in relative densities of protein gene product (PGP) 9.5- and calcitonin gene-related peptide (CGRP)-immunoreactive nerve fibers were observed. CONCLUSION: Patients with recurrent tonsillitis qualified for tonsillectomy reported lower pain intensity than those without recurrent tonsillitis and the pain scores were unrelated to nerve fibers density.

Resumo Introdução: Dor intensa é uma das queixas mais importantes no pós-operatório de uma tonsilectomia. Com frequência, essa dor é descrita pelos pacientes, como comparável à dor que acompanha a tonsilite aguda. Apesar da tonsilite recorrente ser a indicação mais frequente para cirurgia, muitas tonsilectomias são realizadas por outras indicações, e esses pacientes podem não estar familiarizados com essa dor. Objetivo: Verificar se indivíduos com tonsilite recorrente apresentam diferenças na intensidade dolorosa pós-tonsilectomia vs. pacientes com outras indicações para cirurgia, sem histórico de episódios de tonsilite aguda. Método: Foram realizadas 61 tonsilectomias sob anestesia geral, com o uso de um laser potassium titanyl phosphate (KTP) (para que fosse eliminada uma possível influência de uma dissecção agressiva das tonsilas fibrosadas em pacientes com história de tonsilite recorrente), e hemostasia através de ligaduras de vasos sanguíneos nos leitos tonsilares. Os pacientes foram medicados com 37,5 mg de cloridrato de tramadol + 325 mg de paracetamol (comprimidos) durante 10 dias. As variáveis pós-operatórias foram tempo de internação hospitalar, hemorragia e percentual de readmissão. Os pacientes forneceram informações sobre a intensidade da dor em dias consecutivos, duração da dor, perda de peso corpóreo no dia 10 do pós-operatório, intensidade e duração da dificuldade de deglutição, e necessidade de doses adicionais de analgésicos. A velocidade de cicatrização também foi avaliada. Fibras nervosas capsulares foram examinadas histologicamente nas tonsilas resecadas com o uso de imunocorantes para marcadores de fibras nervosas gerais e de sensibilidade. Resultados: As indicações para a cirurgia foram: tonsilite aguda recorrente (34 pacientes), ausência de história de tonsilite recorrente - Tonsilite focal (20) e halitose (7). A intensidade da dor nos dias 3-4 do pós-operatório e a incidência de reinternações em decorrência de desidratação foram significativamente mais altas no grupo sem história de tonsilite recorrente. Não foram observadas diferenças significantes nas densidades relativas de fibras nervosas imunorreativas para protein gene product (PGP) 9.5 e calcitonin gene-related peptide (CGRP). Conclusão: Os pacientes com tonsilite recorrente e qualificados para tonsilectomia informaram menor intensidade da dor em relação aos pacientes sem histórico se tonsilite recorrente, e os escores para dor não apresentaram relação com a densidade das fibras nervosas.

Indicaciones y complicaciones de la adenoidectomia y tonsilectomía en el Hospital Carlos Andrade Marín / Instructions and complications of adenoidectomy and tonsillectomy in the Carlos Andrade Marin Hospital

Introducción: la adenoidectomía y la tonsilectomía (amigdalectomía) son intervenciones quirúrgicas muy frecuentes en Otorrinolaringología. Sin embargo, muchas veces se las realiza sin un criterio valorable y de forma indiscriminada. Aunque en principio las indicaciones generales para estas intervenciones son los procedimientos infecciosos u obstructivos, en la actualidad también se contempla su utilidad en otros cuadros poco comunes como la sospecha de malignidad amigdalina, halitosis de origen amigdalino, nefropatía por IgA y Síndrome PANDAS (Síndrome de Desorden Neurosiquiátrico Pediátrico Autoinmune asociado con Estreptococo). A partir de septiembre de 2009, el Hospital Carlos Andrade Marín amplió la cobertura de atención a la población pediátrica, aumentando el número de estas cirugías en nuestro Servicio. El objetivo de este estudio fue, revisar las indicaciones y complicaciones de estos procedimientos basados en la experiencia de nuestro servicio en la población pediátrica y adulta y cotejarlas con los consensos internacionales. Materiales y métodos: se realizó un estudio descriptivo, retrospectivo utilizando los expedientes clínicos de los pacientes intervenidos en el Servicio de Otorrinolaringología del Hospital Carlos Andrade Marín en el período de mayo 2010 a diciembre 2012. Se analizaron datos demográficos, indicaciones para la realización de cirugía y complicaciones presentadas. Resultados: se intervinieron un total de 120 pacientes en este período. No hubo diferencia en el sexo de los pacientes. El promedio de edad en Tonsilectomía en adulto fue 26 años y en niños, 5 años; en la Adenoidectomía el promedio de edad fue 4.5 años y en los casos de adenoidectomía + tonsilectomía combinada, la edad promedio fue 5 años de edad. Se realizó tonsilectomía en el 45% de los pacientes, adenoidectomía en 30% y adenoidectomía + tonsilectomía combinada en 25% de los casos. La principal indicación para realización de tonsilectomía fue la amigdalitis recurrente (57% casos), mientras que para la adenoidectomía fue la hipertrofia adenoidea obstructiva (60% casos). La tasa total de complicaciones en tonsilectomía fue del 11% (6 / 54); correspondiendo a 4 casos de sangrado precoz (7%), y 2 casos de epistaxis posterior, secundarios a intubación nasotraqueal. En adenoidectomía, la tasa total de complicaciones fue del 5% (2/36), 1 caso por epistaxis severa, y 1 caso por desgarro de mucosa de nasofaringe que fue controlado durante cirugía. No hubo complicaciones en los casos de adenoidectomía + tonsilectomía combinada. No se presentaron decesos en ningún grupo. Conclusiones: la adenoidectomía y la tonsilectomía son procedimientos quirúrgicos eficaces y con baja tasa de complicaciones si se los emplea de acuerdo a los criterios establecidos en consensos internacionales. Nuestra experiencia quirúrgica está acorde a ello.

Introduction: adenoidectomy and tonsillectomy are very common surgeries in Otolaryngology. However, often they are done without a valuable criterion and indiscriminately. Although in principle the general indications for these interventions are infectious or obstructive procedures, currently its utility is also required by other rare cases as suspected tonsillar malignancy, halitosis of tonsillar origin, IgA nephropathy syndrome and PANDAS (Syndrome Pediatric Autoimmune Neuropsychiatric Disorder associated with Streptococcus). From september 2009, Carlos Andrade Marín Hospital expanded coverage for care in the pediatric population, increasing the number of these surgeries in our Service. The aim of this study was to review the indications and complications of these procedures based on the experience of our service in the pediatric and adult population and to align with international consensus. Materials and methods: a descriptive and retrospective study was conducted using the medical records of patients treated in the Department of Otolaryngology, Carlos Andrade Marín Hospital in the period from may 2010 to december 2012. Demographic data, indications for surgery and complications were analyzed. Results: a total of 120 patients were operated during this period. There was no difference in sex of patients. The average age in adult Tonsillectomy was 26, and in children, 5 years; the mean age in Adenoidectomy was 4.5 years and in cases of combined tonsillectomy and adenoidectomy, the average age was 5 years old. Tonsillectomy was performed in 45% of patients, 30% adenoidectomy, and combined tonsillectomy and adenoidectomy in 25% of cases. The main indication for performing tonsillectomy was recurrent tonsillitis (57% cases), while for adenoidectomy was obstructive adenoid hypertrophy (60% cases). The overall complication rate in tonsillectomy was 11% (6/54); corresponding to 4 cases of early bleeding (7%), and 2 cases of posterior epistaxis by nasotracheal intubation. In adenoidectomy, the overall complication rate was 5% (2/36), 1 case of severe epistaxis, and 1 case by tearing of the nasopharyngeal mucosa that was controlled during surgery. There were no complications in cases of adenoidectomy + combined tonsillectomy. No deaths occurred in either group. Conclusions: adenoidectomy and tonsillectomy are effective surgical procedures and have low rate of complications if they are used according to the criteria established by international consensus. Our surgical experience is accordingly.

Poliposis linfangiomatosa de amígdalas palatinas y adenoides: reporte de un caso / Lymphangiomatous polyps of adenoids and palatine tonsils: one case report

Los pólipos linfangiomatosos son malformaciones congénitas de tipo hamartomatosas caracterizados histológicamente por una proliferación linfática vascular con distintos grados de componente fibroso, adiposo y linfático, cubiertos por un epitelio escamoso. Dado a que se conocen por distintos nombres en la literatura, sólo se han descrito alrededor de 30 casos de pólipos linfagiomatosos como tal. De etiopatogenia desconocida, se presentan como una masa polipoidea o papilomatosa en las amígdalas palatinas, con sintomatología variable. Su diagnóstico definitivo es histológico tras una resección completa. No se han reportado casos de malignización ni recurrencia. En el presente trabajo se reporta el caso de un paciente de 5 años con historia de crecimiento amigdalino bilateral de dos años de evolución. La biopsia definitiva demuestra una poliposis linfangiomatosa de amígdalas palatinas y adenoides.

Lymphangiomatous polyps are hamartomatous congenital malformations. They are histologically characterized by a vascular lymphatic proliferation associated with fibrous, adipose and lymphatic components covered by squamous epithelium. There are only 30 cases described in the literature by the name of lymphangiomatous polyp, since it has multiple denominations. Even though their etiopathogenesis is unknown, their clinical presentation is described as a polypoid mass in the palatine tonsils, which may have multiple manifestations. The diagnosis is made histologically after complete resection. There have not been reports of malignant transformation nor recurrence. We present a case of a five year old patient with history of bilateral palatine tonsil growth. Final biopsy described lymphangiomatous polyps of adenoids and palatine tonsils.

Respiração oral e alteração de fala em crianças / Oral breathing and speech disorders in children

OBJETIVO: Verificar alterações na fala em crianças respiradoras orais e relacioná-las com o tipo respiratório, a etiologia, o gênero e a idade. MÉTODO: Foram avaliados 439 respiradores orais com idade entre quatro e 12 anos. Considerou-se atraso no desenvolvimento de fala a presença de alterações em crianças acima de cinco anos de idade. As alterações observadas foram interposição de língua (IL), ceceio frontal (CF), troca articulatória (TA), omissões (OM) e ceceio lateral (CL). Relacionou-se etiologia da respiração oral, gênero, idade, tipo respiratório e alterações de fala. RESULTADOS: Alterações de fala foram diagnosticadas em 31,2% dos pacientes sem relação com o tipo respiratório: oral ou misto. Maior frequência de trocas articulatórias e mais de uma alteração de fala ocorreram no gênero masculino. IL foi documentada em 53,3% pacientes, seguida por TA em 26,3% e CF em 21,9%. Concomitância de duas ou mais alterações de fala ocorreu em 24,8% das crianças. CONCLUSÃO: Respirar pela boca pode afetar o desenvolvimento da fala, a socialização e o desempenho escolar. A detecção precoce da respiração oral é essencial para prevenir e minimizar seus efeitos negativos sobre o desenvolvimento global dos indivíduos.

OBJECTIVE: To assess speech alterations in mouth-breathing children, and to correlate Mouth breathing; them with the respiratory type, etiology, gender, and age. METHOD: A total of 439 mouth-breathers were evaluated, aged between 4 and 12 years. The presence of speech alterations in children older than 5 years was considered delayed speech development. The observed alterations were tongue interposition (TI), frontal lisp (FL), articulatory disorders (AD), sound omissions (SO), and lateral lisp (LL). The etiology of mouth breathing, gender, age, respiratory type, and speech disorders were correlated. RESULTS: Speech alterations were diagnosed in 31.2% of patients, unrelated to the respiratory type: oral or mixed. Increased frequency of articulatory disorders and more than one speech disorder were observed in males. TI was observed in 53.3% patients, followed by AD in 26.3%, and by FL in 21.9%. The co-occurrence of two or more speech alterations was observed in 24.8% of the children. CONCLUSION: Mouth breathing can affect speech development, socialization, and school performance. Early detection of mouth breathing is essential to prevent and minimize its negative effects on the overall development of individuals.

Avaliação da postura corporal em crianças e adolescentes respiradores orais / Assessment of the body posture of mouth-breathing children and adolescents

OBJETIVO: Verificar a associação do tipo respiratório oral (RO) e nasal (RN) e da classificação da postura corporal em variáveis clínicas de crianças e adolescentes com a síndrome do respirador oral, em relação a um grupo-controle de mesma faixa etária. MÉTODOS: Estudo analítico do tipo observacional e transversal, com grupo-controle, realizado em hospital universitário. Foram incluídas crianças maiores de 5 anos, distribuídas em dois grupos: controle saudável (RN) e grupo RO. O grupo RO incluiu pacientes com diagnóstico de síndrome do respirador oral confirmado por exame clínico médico e nasofibroscopia. Participaram do grupo-controle voluntários saudáveis da mesma faixa etária, cujo tipo RN foi confirmado por avaliação médica. Todos os participantes foram submetidos à avaliação postural. Para análise dos dados, foram utilizados os testes: não paramétrico de Mann-Whitney, qui-quadrado e exato de Fisher, considerando-se nível de significância de 0,05 por cento. RESULTADOS: Foram incluídos 306 RO e 124 RN. O tipo RO conferiu maior prevalência no gênero masculino (p = 0,0002), maior grau e frequência de obstrução nasal e tamanho das amígdalas (p = 0,0001) em comparação ao RN. Também apresentou maior incidência de rinite alérgica (p = 0,0001), padrão respiratório torácico (p = 0,0001), palato ogival (p = 0,0001) e classificação postural desfavorável (p = 0,0001) em relação ao grupo-controle. Os índices de classificação postural foram diretamente proporcionais à obstrução nasal (p = 0,0001) e ao gênero masculino (p = 0,0008). CONCLUSÕES: Alterações posturais foram significativamente mais frequentes nas crianças do grupo com síndrome do respirador oral, o que reforça a necessidade de precocidade no tratamento interdisciplinar dessa síndrome.

OBJECTIVE: To investigate associations between mouth breathing (MBr), nose breathing (NBr) and body posture classification and clinical variables in children and adolescents, by comparing patients with mouth breathing syndrome with a control group of similar age. METHODS: This was an observational, analytical, controlled, cross-sectional study conducted at a university hospital. Children aged 5 years or more were recruited to one of two groups: healthy controls (NBr) or an MBr group. The MBr group comprised patients with a diagnosis of mouth breathing syndrome confirmed by clinical examination by a physician plus nasal endoscopy. The control group comprised healthy volunteers of the same age, with NBr confirmed by medical examination. All participants underwent postural assessment. Data were analyzed using the Mann-Whitney nonparametric test, the chi-square test and Fisher’s exact test, to a significance level of 0.05 percent. RESULTS: A total of 306 MBr and 124 NBr were enrolled. Mouth breathers were more likely to be male (p = 0.0002), have more frequent and more severe nasal obstruction and larger tonsils (p = 0.0001) than NBr. Mouth breathers also exhibited higher incidence rates of allergic rhinitis (p = 0.0001), of thoracic respiratory pattern (p = 0.0001), high-arched palate (p = 0.0001) and unfavorable postural classifications (p = 0.0001) with relation to the control group. Postural classification scores were directly proportional to nasal obstruction (p = 0.0001) and male sex (p = 0.0008). CONCLUSIONS: Postural problems were significantly more common among children in the group with mouth breathing syndrome, highlighting the need for early interdisciplinary treatment of this syndrome.

OBJETIVO: Investigar a etiologia, as principais manifestações clínicas e as alterações presentes em crianças de 3 a 9 anos, respiradoras orais, residentes na região urbana de Abaeté (MG). MÉTODOS: Estudo com amostra aleatória representativa da população do município de 23.596 habitantes. Clinicamente, foram consideradas respiradoras orais as crianças que roncavam, dormiam com a boca aberta, babavam no travesseiro e apresentavam queixas de obstrução nasal freqüente ou intermitente. As crianças com diagnóstico clínico de respirador oral foram submetidas a endoscopia nasal, teste alérgico cutâneo e raio X do cavum, hemograma, contagem de eosinófilos, dosagem de IgE total e parasitológico de fezes. Os dados foram analisados utilizando o programa SPSS® versão 10.5. RESULTADOS: As principais causas da respiração oral foram: rinite alérgica (81,4 por cento), hipertrofia de adenóides (79,2 por cento), hipertrofia de amígdalas (12,6 por cento) e desvio obstrutivo do septo nasal (1,0 por cento). As principais manifestações clínicas do respirador oral foram: dormir com a boca aberta (86 por cento), roncar (79 por cento), coçar o nariz (77 por cento), babar no travesseiro (62 por cento), dificuldade respiratória noturna ou sono agitado (62 por cento), obstrução nasal (49 por cento) e irritabilidade durante o dia (43 por cento). CONCLUSÃO: Algumas manifestações clínicas são muito freqüentes na criança respiradora oral. Essas manifestações devem ser reconhecidas e consideradas no diagnóstico clínico da respiração oral.

OBJECTIVE: To investigate the etiology, main clinical manifestations and other concurrent findings in mouth-breathing children aged 3 to 9 years and resident in the urban area of Abaeté (MG), Brazil. METHODS: This study was based on a representative random sample of the town population, of 23,596 inhabitants. Clinical diagnosis of mouth-breathing was defined as a combination of snoring, sleeping with mouth open, drooling on the pillow and frequent or intermittent nasal obstruction. Children with a clinical diagnosis of mouth breathing underwent nasal endoscopy, allergy skin tests and X ray of the rhinopharynx, full blood tests, eosinophil counts, total IgE assay and fecal parasitology. Data were analyzed using SPSS® version 10.5. RESULTS: The main causes of mouth breathing were: allergic rhinitis (81.4 percent), enlarged adenoids (79.2 percent), enlarged tonsils (12.6 percent), and obstructive deviation of the nasal septum (1.0 percent). The main clinical manifestations of mouth breathers were: sleeping with mouth open (86 percent), snoring (79 percent), itchy nose (77 percent), drooling on the pillow (62 percent), nocturnal sleep problems or agitated sleep (62 percent), nasal obstruction (49 percent), and irritability during the day (43 percent). CONCLUSION: Certain clinical manifestations are very common among mouth-breathing children. These manifestations must be recognized and considered in the clinical diagnosis of mouth breathing.

Avaliação de um novo enxaguatório na formação de cáseos amigdalianos / Evaluation of a new mouthwash on caseous formation

Os cáseos amigdalianos afetam uma significativa porcentagem da população. As cirurgias, conservadoras ou não, têm sido as únicas alternativas viáveis de tratamento. Entretanto, ainda hoje não há um método econômico e não-invasivo de tratamento que apresente resultados satisfatórios. OBJETIVOS: Os objetivos deste estudo são avaliar a eficiência de um enxaguatório, cujos ingredientes ativos associam substâncias oxigenantes e antimicrobianas, na diminuição da formação dos cáseos amigdalianos e da saburra lingual, cuja etiologia é semelhante à dos cáseos, e avaliar a redução da concentração dos compostos sulfurados voláteis (CSVs). FORMA DE ESTUDO: Estudo clínico e experimental, randomizado, duplo-cego, placebo-controlado. MATERIAL E MÉTODO: Foi utilizada uma amostra de 50 voluntários, com queixa de tonsilite crônica caseosa há mais de um ano. A pesquisa foi realizada em 2005, nas cidades de São Paulo e Campinas. RESULTADOS: Para o grupo que utilizou a solução placebo, não houve correlação entre as variáveis nem significância estatística nos resultados. Para o grupo que utilizou o enxaguatório, os resultados foram significativos em todos os quesitos analisados. CONCLUSÕES: O novo enxaguatório demonstrou ser uma alternativa conservadora viável para o tratamento da tonsilite crônica caseosa, sendo eficiente também na redução da formação de saburra lingual e concentração dos CSVs.

Tonsil caseous affects a significant percentage of the population. Surgeries, conservative or not, have been the only viable alternatives of treatment. However, today there is still not, up to now, an economical and non-invasive treatment that presents satisfactory results. AIMS: The objectives of this study are to evaluate the efficiency of a mouthwash, with active ingredients that associate oxygenating and antimicrobial substances, in the reduction of caseous and tongue coating formation, whose etiology is similar to caseous, and to evaluate the reduction of the volatile sulfur compounds (VSCs) concentration. STUDY DESIGN: Double blind, placebo-controlled, randomized, clinical and experimental study. MATERIAL E METHODS: A sample of 50 volunteers with more than one year of chronic caseous tonsillitis complaint used it. The research was carried out in 2005, in the cities of São Paulo and Campinas. RESULTS: For the group that used the placebo solution, there was no correlation between the variables or statistical significance in the results. For the group that used the mouthwash, the results were significant in all analyzed questions. CONCLUSIONS: This new mouthwash proved to be a viable conservative alternative for the treatment of tonsil caseous, being also efficient in the reduction of tongue coating formation and VSCs concentration.

Linfomas não-Hodgkin extranodais em Salvador-Bahia: aspectos clínicos e classificação histopatológica segundo a OMS-2001 / Extranodal non-Hodgkins lymphomas in Salvador, Brazil: clinical aspects and histopathological classification according to the WHO-2001 guidelines

Linfomas não-Hodgkin (LNH) extranodais representam cerca de um terço de todos os linfomas e atualmente apresentam taxa de incidência maior que a de linfomas nodais. Diferenças entre LNH nodais e extranodais incluem etiologia, formas de apresentação e resposta terapêutica, entretanto não dispomos de dados na nossa população. Este estudo teve como objetivo caracterizar os LNH extranodais diagnosticados no Hospital Aristides Maltez, em Salvador-Bahia. Foram avaliados, retrospectivamente, 145 diagnósticos de linfoma não-Hodgkin, segundo a OMS-2001, no período de janeiro de 1999 a julho de 2001. A freqüência de linfomas extranodais foi de 30,3 por cento. A idade média dos pacientes foi de 55,6 anos e a relação homem/mulher foi de 1:1. A maioria dos pacientes apresentava estadios avançados (III ou IV de Ann Arbor), presença de sintomas B, LDH normal, bom desempenho pela escala do ECOG e IPI entre zero e dois. Nove pacientes estão vivos e em remissão completa (22,5 por cento) após um seguimento médio de 23 meses. O sítio extranodal mais comumente acometido foram as tonsilas, seguidas pela cavidade oral, pele e trato gastrointestinal, dentre outros. O linfoma difuso de grandes células B foi o mais comum subtipo histológico, seguido pelo linfoma anaplásico de grandes células. Concluímos que o mais freqüente sítio extranodal de apresentação em nosso estudo difere da maioria da literatura, porém nossa freqüência de linfoma extranodal é semelhante à mesma.

Extranodal non-Hodgkins lymphomas represent approximately one third of all lymphomas and currently have an incidence higher than nodal lymphomas. Differences in etiology, presentation and outcome of these lymphomas have been reported. However, there are no data in our population. This study was carried out in the Pathological Anatomy Service of Aristides Maltez Hospital in Salvador, Bahia. One hundred and forty-five non-Hodgkins lymphomas cases according to the WHO-2001 classification detected between January 1999 and July 2001 were evaluated. The frequency of extranodal lymphomas was 30.3 percent. The mean age of the patients was 55.6 percent years and the male/female ratio was 1:1. The majority of the patients presented with advanced stages, B symptoms, normal LDH, ECOG between o and 2 and IPI between O and 2. Nine patients are still alive in complete remission (22.5 percent) with a mean follow-up of 23 months. The main extranodal sites were the tonsils followed by the oral cavity, skin and gastrointestinal tract. Diffuse large B-Cell lymphoma was the mains histological subtype, followed by anaplastic large-cell lymphoma. In summary, the mains extranodal site in our study was different from the masority of reports. However our extranodal lymphoma frequency was similar.

Impacted cisterna magna without syringomyelia associated with lancinating headache, throbbed nuchal pain and paraparesis treated byposterior fossa decompression

A 29-year-old woman with acute lancinating headache, throbbed nuchal pain and subacute paraparesis underwent brain MRI in supine position that depicted: the absence of the cisterna magna, filled by non herniated cerebellar tonsils and compression of the brain stem and cisternae of the posterior fossa, which are aspects of the impacted cisterna magna without syringomyelia and without hydrocephalus. During eight days, pain was constant and resistant to drug treatment. Osteodural-neural decompression of the posterior fossa, performed with the patient in sitting position, revealed: compression of the brainstem, fourth ventricle and foramen of Magendie by herniated cerebellar tonsils, which were aspirated. Immediately after surgery, the headache and nuchal pain remmited. MRI depicted the large created cisterna magna and also that the cerebellar tonsils did not compress the fourth ventricle, the foramen of Magendie and the brainstem, besides the enlargement of posterior fossa cisternae. Four months after surgery, headache, nuchal pain and paraparesis had disappeared but hyperactive patellar and Achilles reflexes remained.

Uma paciente de 29 anos de idade com quadro agudo de cefaléia lancinante, dor terebrante na nuca e paraparesia subaguda foi submetida a RM do encéfalo, em posição supina, que revelou: ausência da cisterna magna, preenchida por tonsilas cerebelares não herniadas e compressão do tronco encefálico e das cisternas da fossa posterior, compatíveis com o diagnóstico de cisterna magna impactada sem siringomielia e sem hidrocefalia. Por oito dias a dor foi constante e resistente aos analgésicos. Com a paciente em posição sentada, foi realizada descompressão osteodural-neural da fossa posterior associada a aspiração das tonsilas cerebelares. Os achados perioperatórios foram caracterizados por herniação das tonsilas cerebelares que comprimiam o tronco cerebral, o quarto ventrículo e o forame de Magendie. No pós-operatório imediato houve remissão da cefaléia e da dor na nuca. A RM evidenciou a cisterna magna recém-criada, alargamento do quarto ventrículo e das cisternas do tronco encefálico. Quatro meses depois, a paciente continuava sem cefaléia, sem dor na nuca e sem paraparesia. Entretanto, permaneceu a hiperatividade dos reflexos patelares e aquileus.

Amigdalopexia cerebelosa en el manejo de la malformación de chiari de tipo I / Cerebellar amygdalopexy in the management of Chiari I malformation

Antecedentes. El tratamiento de la malformación de Chiari de tipo I asociada a siringomielia es controvertido. En este trabajo se presenta un análisis clínico, quirúrgico y radiológico de los pacientes con esta afección que fueron manejados durante un periodo de doce años. Material y métodos. Se incluyeron 48 pacientes, donde se encontró un discreto predominio en el sexo femenino. El cuadro clínico estuvo dominado por cefalea, dolor cervical, signos y síntomas cerebelosos, afección de nervios craneales bajos y lesión de la vía piramidal. Resultados. Tanto el grado de descenso amigdalino como el tamaño de la siringomielia fueron muy variables, sin encontrar correlación entre ambos. La cirugía consistió en una craniectomía occipital, laminectomía de C1, ascenso de amígdalas cerebelosas mediante coagulación bipolar y plastía de duramadre. Los mejores resultados clínicos se obtuvieron en el dolor y los síntomas cerebelosos, mientras que los peores fueron en la afección de los nervios craneales bajos y de la vía piramidal, sin embargo, en la gran mayoría de los pacientes se logró detener la progresión de los síntomas. No se presentaron complicaciones serias en el presente estudio. Conclusión. El procedimiento propuesto ofrece una alternativa segura, efectiva y comparable con otros métodos más riesgosos para el manejo de esta malformación.

BACKGROUND: The treatment of Chiari I malformation associated with syringomyelia is controversial. OBJECTIVE: We describe a series of patients with this disease treated during a twelve-year period. We also present clinical, surgical and radiological findings. MATERIAL AND METHODS: Forty eight patients were included; a non significant female predominance was found. Clinical course was characterized by headache, cerebellar signs and symptoms, neck pain and involvement of lower cranial nerves and pyramidal tract. The degree of tonsillar descent and syringomyelia size varied and a correlation between them was not found. Surgery consisted in an occipital craniectomy, C1 laminectomy and tonsillar elevation through bipolar coagulation and duraplasty. RESULTS: The best results were observed in pain and cerebellar symptoms, while a deficit of lower cranial nerves and pyramidal tract were observed. However, in most patients we were able to slow symptom progression. No adverse effects were documented. CONCLUSIONS: The surgicalprocedureproposed herein is an effective and safe treatment alternative for this malformation, and its results are comparable to other riskier procedures.

Differences in lymphocytes and the expression of FasL,ICAM-1 in the tonsillar HEVs associated with IgA nephropathy and recurrent tonsillitis / 中国免疫学杂志

Objective:To investigate the difference in expression of FasL and ICAM-1 in the tonsillar HEV associated with IgA nephropathy (IgAN) and recurrent tonsillitis (RT).Methods:Human tonsils were obtained from the patients with RT (n=18) or IgAN (n=12).HE staining was used to show the morophometry of the tonsillar HEV.CD20+,CD3+ lymphocytes and distribution of FasL and ICAM-1 in the HEV were observed with immunohistochemical stained tissue section.The quantitatively experimental data from pathological image analysis were compared between IgAN and RT group.Results:(1)The expressing intensity of ICAM-1 was (0.435 5?0.002) in IgAN group and (0.239 5?0.010 4) in RT group,respectively (P0.05).Conclusion:A significant increase in the number of tonsillar HEV and increased lymphocytes in HEVs may indicate the abnormalities in peripheral blood in the patients with IgAN,thus leading to an overactivation of the tonsillar HEVs that induce Fas-dependent apoptosis in such patients.A stronger biological effective adhesion molecule promotes the transendothelial migration of lymphocytes across HEVs of palatine tonsil,which appears to be connected with the development of IgAN.
