Objective reduction in adenoid tissue after mometasone furoate treatment

Objective: Chronic rhinitis and adenoid hypertrophy are the main causes of nasal obstruction in children and proper treatment of these factors seem essential for controlling nasal obstructive symptoms. This study aims to evaluate the effects of topical mometasone treatment on symptoms and size of adenoid tissue in children with complaints of nasal obstruction and to compare this approach to continuous nasal saline douching plus environmental control alone. Methods: Fifty-one children with nasal obstructive complaints were submitted to a semi-structured clinical questionnaire on nasal symptoms, prick test and nasoendoscopy. Nasoendoscopic images were digitalized, and both adenoid and nasopharyngeal areas were measured in pixels. The relation adenoid/nasopharyngeal area was calculated. Patients were subsequently re-evaluated in two different periods: following 40 days of treatment with nasal douching and environmental prophylaxis alone; and after an subsequent 40 day-period, when topical mometasone furoate (total dose: 100 mu g/day) was superposed. Results: Nasal symptoms and snoring significantly improved after nasal douching, and an additional gain was observed when mometasone furoate was included to treatment. Saline douching did not influence the adenoid area, whereas a significant reduction on adenoid tonsil was observed after 40 days of mometasone treatment (P < 0.0001). Conclusion: Nasal saline douching significantly improved nasal symptoms without interfering in adenoid dimension. In contrast, mometasone furoate significantly reduced adenoid tissue, and led to a supplementary improvement of nasal symptoms. (C) 2012 Elsevier Ireland Ltd. All rights reserved.

Craniofacial morphology and sleep apnea in children with obstructed upper airways: Differences between genders

Objective: To correlate sleep apnea with craniofacial characteristics and facial patterns according to gender. Methods: In this prospective survey we studied 77 male and female children (3-12 years old) with an upper airway obstruction due to tonsil and adenoid enlargement. Children with lung problems, neurological disorders and syndromes, obstructive septal deviation, previous orthodontic treatment, orthodontic surgeries or oral surgeries, or obesity were excluded. Patients were subjected to physical examinations, nasal fiberoptic endoscopy, teleradiography for cephalometric analysis, and polysomnography. Methods: Cephalometric analysis included the following skeletal craniofacial measurements: facial axis (FA), facial depth (FD), mandibular plane angle (MP), lower facial height (LFH), mandibular arch (MA), and vertical growth coefficient (VERT) index. Results: The prevalence of sleep apnea was 46.75% with no statistical difference between genders. Among children with obstructive sleep apnea (Apneia Hypopnea Index - AHI >= 1) boys had higher AHI values than girls. A predominance of the dolichofacial pattern (81.9%) was observed. The following skeletal craniofacial measurements correlated with AHI in boys: FD (r(s) = -0.336/p = 0.020), MP (r(s) = 0.486/p = 0.00), and VERT index (r(s) = -0.337/p = 0.019). No correlations between craniofacial measurements and AHI were identified in girls. Conclusions: Craniofacial morphology may influence the severity of sleep apnea in boys but not in girls.

Influence of adenotonsillectomy on hard palate dimensions

Objective: To evaluate hard palate width and height in mouth-breathing children pre- and post-adenotonsillectomy. Methods: We evaluated 44 children in the 3-6 year age bracket, using dental study casts in order to determine palatal height, intercanine width, and intermolar width. The children were divided into two groups: nasal breathing (n = 15) and mouth breathing (n = 29). The children in the latter group underwent adenotonsillectomy. The study casts were obtained prior to adenotonsillectomy, designated time point 1(11), at 13 months after adenotonsillectomy (T2), and at 28 months after adenotonsillectomy (13). Similar periods of observation were obtained for nasal breathing children. Results: At T1, there was a significantly lower intercanine width in mouth breathing children; intermolar width and palate height were similar between groups. After surgery, there was a significant increase in all the analyzed parameters in both groups, probably due to facial growth. Instead, the increase in intercanine width was substantially more prominent in mouth breathing children than in nasal breathing children, and the former difference failed in significance after the procedure. Conclusions: There were no significant differences between the nasal-breathing and mouth-breathing children in terms of intermolar width and palatal height prior to or after tonsillectomy. Although intercanine width was initially narrower in the mouth-breathing children, it showed normalization after the surgical procedure. These results confirm that the restoration of nasal breathing is central to proper occlusal development. (C) 2012 Elsevier Ireland Ltd. All rights reserved.

Multifocal pattern electroretinography for the detection of neural loss in eyes with permanent temporal hemianopia or quadrantanopia from chiasmal compression

Aims To evaluate the ability of multifocal transient pattern electroretinography (mfPERG) to detect neural loss and assess the relationship between mfPERG and visual-field (VF) loss in eyes with chiasmal compression. Methods 23 eyes from 23 patients with temporal VF defects and band atrophy of the optic nerve and 21 controls underwent standard automated perimetry and mfPERG using a stimulus pattern of 19 rectangles, each consisting of 12 squares. The response was determined for the central rectangle, for the nasal and temporal hemifields (eight rectangles each) and for each quadrant (three rectangles) in both patients and controls. Comparisons were made using variance analysis. Correlations between VF and mfPERG measurements were verified by linear regression analysis. Results Mean +/- SD mfPERG amplitudes from the temporal hemifield (0.50 +/- 0.17 and 0.62 +/- 0.32) and temporal quadrants (superior 0.42 +/- 0.21 and 0.52 +/- 0.35, inferior 0.51 +/- 0.23 and 0.74 +/- 0.40) were significantly lower in eyes with band atrophy than in controls (0.78 +/- 0.24, 0.89 +/- 0.28, 0.73 +/- 60.26, 0.96 +/- 0.36, 0.79 +/- 0.26 and 0.91 +/- 0.31, respectively). No significant difference was observed in nasal hemifield measurements. Significant correlations (0.36-0.73) were found between VF relative sensitivity and mfPERG amplitude in different VF sectors. Conclusions mfPERG amplitude measurements clearly differentiate eyes with temporal VF defect from controls. The good correlation between mfPERG amplitudes and the severity of VF defect suggests that mfPERG may be used as an indicator of ganglion cell dysfunction.

Mönckeberg's sclerosis – is the artery the only target of calcification?

Abstract Background Since its first description, Mönckeberg's sclerosis has only been related to arterial media calcification, being listed among the primary diseases of the vessels. Case presentation We report here a clinically and histologically confirmed case of Mönckeberg's sclerosis in which the patient presented with massive areas of soft tissue calcifications in the pharynx and larynx. Polysomnographic parameters showed severe obstructive apnea refractory to nasal continuous positive airway pressure. Clinical and laboratory findings excluded concomitant endocrine or rheumatological diseases. Conclusion Our data provide a new insight about Mönckeberg's sclerosis, i.e., the fact that the etiopathogenic process involved in the phenomenon of calcification may not be restricted only to the arteries, but may occur in the entire organism. Further studies of the etiopathogenesis of this disease are needed.

Intranasal tooth and associated rhinolith in a patient with cleft lip and palate

We report the case of a 9-year-old girl who presented with a complaint of a malodorous bloody discharge from the left naris. The patient had previously undergone a complete repair of left-sided cleft lip and palate. Clinical examination revealed hyperplasia of the nasal mucosa on the left side. X-ray examination of the nasal cavity demonstrated a radiopaque structure that resembled a tooth and a radiopaque mass similar to an odontoma that was adherent to the root of the suspected tooth. With the patient under general anesthesia, the structure was removed. On gross inspection, the structure was identified as a tooth with a rhinolith attached to the surface of its root. Microscopic examination revealed normal dentin and pulp tissue. A nonspecific inflammatory infiltrate was observed around the rhinolith, and areas of regular and irregular mineralization were seen. Some mineralized areas exhibited melanin-like brownish pigmentation. Areas of mucus with deposits of mineral salts were also observed. Rare cases of an intranasal tooth associated with a rhinolith have been described in the literature. We believe that this case represents only the second published report of an intranasal tooth associated with a rhinolith in a patient with cleft lip and palate

Morphological characterization of the nasopalatine region in human fetuses and its association to pathologies

The nasopalatine region is composed of structures such as the vomeronasal organ and nasopalatine duct. The nasopalatine duct may provide the communication of the mouth to the nasal cavity in human fetuses and can be obliterated in an adult human. Knowledge on the development of the nasopalatine region and nasopalatine duct in humans is necessary for understanding the morphology and etiopathogenesis of lesions that occur in this region. Objective: The aim of the present study was to describe the morphological aspects of the nasopalatine region in human fetuses and correlate these aspects with the development of pathologies in this region. Material and Methods: Five human fetuses with no facial or palatine abnormalities were used for the acquisition of specimens from the nasopalatine region. After demineralization, the specimens were histologically processed. Histological cuts were stained with methylene blue to orient the cutting plane and hematoxylin-eosin for the descriptive histological analysis. Results: The age of the fetuses was 8.00, 8.25, 9.00 and 9.25 weeks, and it was not possible to determine the age in the last one. The incisive canal was observed in all specimens as an opening delimited laterally by the periosteum and connecting oral and nasal cavity. The nasopalatine duct is an epithelial structure with the greatest morphological variation, with either unilateral or bilateral occurrence and total patent, partial patent and islet forms. The vomeronasal organ is a bilateral epithelized structure located alongside the nasal septum above the incisive canal in all the fetuses. Conclusions: The incisive canal, nasopalatine duct and vomeronasal organ are distinct anatomic structures. The development of nasopalatine duct cysts may occur in all forms of the nasopalatine duct.

Neurovascular anatomical variations in the anterior palate observed on CBCT images

Objective: This study aimed to assess the presence of additional foramina and canals in the anterior palate region, through cone beam computed tomography (CBCT) images, describing their location, direction, and diameter. Materials & Methods: CBCT exams of 178 subjects displaying the anterior maxilla were included and the following parameters were registered: gender; age group; presence of additional foramina in the anterior palate (AFP) with at least 1 mm in diameter; location and diameter of AFP; and direction of bony canals associated with AFP. Results: Twenty-eight patients (15.7%) presented AFP and in total 34 additional foramina were registered. No statistical differences between patients with or without AFP were found for gender or age. The average diameter of AFP was 1.4 mm (range from 1 to 1.9 mm). Their location was variable, with most of the cases occurring in the alveolar process near the incisors or canines (n = 27). In 18 cases, AFP was associated with bony canals with upward or oblique direction toward the anterior nasal cavity floor. In 14 cases, the canal presented as a direct extension of the canalis sinuosus, in an upward direction laterally to the nasal cavity aperture. In two cases, the canal was observed adjacent to the incisive and joined the nasopalatine canal superiorly. Discussion: CBCT images have a crucial role in the recognition of anatomical variations by allowing detailed tridimensional evaluations. Additional foramina and canals in the anterior region of the upper jaw are relatively frequent. Practitioners should be aware and trained to identify these variations. Conclusions: Over 15% of the population studied had additional foramina in the anterior palate, between 1 mm and 1.9 mm wide, with variable locations. In most cases the canals associated with these foramina either presented as a direct extension of the canalis sinuosus, or coursed towards the nasal cavity floor.

Nevo de células fusiformes de Reed na conjuntiva

Os autores relatam um caso de nevo de Reed, lesão que apresenta aspecto histológico de malignidade, mas tem evolução benigna. Paciente de 48 anos, masculino, cor parda, apresentava pterígio nasal no olho direito, associado a uma lesão pequena e pouco pigmentada localizada na cabeça do mesmo. Realizou-se exérese de ambos, sem intercorrências, sem sinais de recidiva. O exame histopatológico revelou lesão com bordas definidas, restrita ao epitélio, constituída por células fusiformes perpendiculares à superfície, com pigmentação melânica esparsa. O diagnóstico inicial foi nevo de Spitz, mas, posteriormente, chegou-se à conclusão que se tratava do nevo de células fusiformes de Reed. O presente relato é o segundo na literatura mundial e o primeiro no Brasil.

Facial lesions caused by renal osteodystrophy in a patient with chronic renal insufficiency: a case report

PURPOSE: Chronic renal insufficiency (CRI) is the last stage of a chronic renal condition in which the kidney loses its filtration and endocrine functions. Chronic endocrine hypofunction causes generalized damage to the body known as Uremic Syndrome, which affects the central nervous system as well as the cardiovascular, hematologic, dermatologic, ophthalmic, endocrine, respiratory, gastrointestinal and skeletal systems. The present study reports the case of a female patient with CRI who presented facial osteodystrophy of the osteitis fibrosa type, and highlights the main features of this condition. CASE DESCRIPTION: A 24-year old, female, Caucasian patient presented chronic glomerulonephritis recurrence and lost the transplanted kidney five years before, undergoing arteriovenous fistula hemodialysis three times a week. She presented swelling of the left masseter area with a hard consistency on palpation, covered by intact skin, swelling at the bottom of the left atrium, with a hard consistency on palpation, a mucosa-like color and absence of inflammation signs, suggesting expansive bone lesions on the face. These features were compatible with hyperparathyroidism brown tumor and/or osteodystrophy. The CT scan showed expansive bone lesions of heterogeneous appearance on the left jaw, maxilla/nasal floor, and right frontotemporal suture areas. The clinical and histopathological characteristics of the lesion, in association with PHT hormone high serum levels led to renal osteodystrophy diagnosis. The patient was referred to the nephrology services. CONCLUSION: Osteodystrophic bone alterations have a high prevalence in renal disease patients, and the dentist must take these alterations into consideration in bone lesion diagnosis for this specific group of patients.

Resultados da ressecção de hemangiomas infantis nasais em fase proliferativa: abordagem segura para os tumores centrais da face

INTRODUÇÃO: O hemangioma infantil é o tumor benigno mais comum da infância, predominando na região cervicofacial. É caracterizado por apresentar 3 fases distintas, observando-se frequentemente regressão espontânea dessas lesões. No entanto, sequelas residuais ou deformidades das estruturas anatômicas em crescimento podem ocorrer. A abordagem cirúrgica precoce e definitiva é indicada, em decorrência da localização dos hemangiomas nasais e seu potencial desfigurante, visando à obtenção de bons resultados estéticos e preservação anatômica. O objetivo do presente estudo foi analisar os resultados da abordagem cirúrgica definitiva para hemangiomas proliferativos nasais, com base em uma avaliação objetiva. MÉTODO: No período de 1997 a 2009, 20 pacientes portadores de hemangiomas nasais em fase proliferativa foram submetidos a tratamento cirúrgico. As lesões foram avaliadas segundo local de acometimento e tratamento realizado. Foram analisados índices de complicações e necessidade de procedimentos adicionais. Os resultados estéticos foram avaliados por avaliadores independentes. RESULTADOS: As lesões estavam localizadas na ponta nasal em 50% dos pacientes; no dorso, em 20%; em todas as subunidades, em 15%; nas áreas paranasais, em 10%; e na unidade alar, em 5%. A ressecção foi total em 60% dos pacientes e subtotal em 40%. O período médio de acompanhamento foi de 42,6 meses. A média de procedimentos cirúrgicos por paciente foi de 1,3 + 0,7. Nenhuma complicação importante foi observada. Os resultados foram positivamente avaliados quanto a redução do volume da lesão e melhora do contorno facial, corroborando a conduta proposta. CONCLUSÕES: No manejo dos hemangiomas nasais, o tratamento cirúrgico definitivo pode ser considerado uma alternativa segura e eficaz, com baixas taxas de complicação.

Ablefaro macrostomia - síndrome e audição: relato de dois casos familiares

Introdução: Síndrome de Ablefaro MAcrostomia (AMS) é uma condição rara que compreende pálpebras ausentes ou curto, orelhas anormais, macrostomia, genitália anômalo, pele redundante e cabelos ausente. Brancati et al (2004) relataram uma ocorrência estimada de perda auditiva em 70% desta população. Estudos específicos sobre a audição em AMS não estavam presentes nos jornais que compilados. Relato dos casos: Paciente 1 é o primeiro filho de um ano de idade, a mãe 23 anos e pai de 25 anos de idade, não consangüíneos. Suas características clínicas são pouco cabelo no couro cabeludo, orelhas em forma de taça, raiz nasal larga, narinas antevertidas, macrostomia, os dedos com membranas, pele redundante e hipoplasia mamilos e lábios. Ela não tem atraso no desenvolvimento neuropsicomotor e a fala é normal. A audição foi avaliada aos 15 anos com uma perda auditiva em 6 kHz. Paciente 2 é o terceiro filho do mesmo casal. Ela tem falta grave das pálpebras, uma ponte nasal baixa com narinas hipoplásica e anteversão, macrostomia, orelhas anormalmente modelados, a ausência de mamilos, um de 6 cm onfalocele, ânus anteriormente localizado, hipoplasia dos grandes lábios, unhas hipoplasia, atenuação distal de falanges e pele redundante. Ela está se desenvolvendo com atraso no desenvolvimento neuropsicomotor, fala normal e perda auditiva condutiva leve bilateral. A avaliação audiológica incluiu quatro procedimentos: história clínica audiológica, inspeção otológica, imitanciometria, audiometria tonal e discurso. Conclusões: Os pacientes estudados com AMS apresentaram perda auditiva leve e esta perda de audição pode ser considerado como uma parte do fenótipo AMS sendo compatível os achados com a literatura.

Fisioterapia respiratória em pacientes com fissuras labiopalatinas : rotinas do Hospital de Reabilitação de Anomalias Craniofaciais

As malformações craniofaciais apresentam-se como alterações frequentes sendo as fissuras labiopalatinas mais comumente encontradas. Essa condição leva à ocorrência de infecções de vias aéreas superiores e broncopneumonias pois a comunicação entre a cavidade oral e nasal modifica toda depuração de vias aéreas. O Setor de Fisioterapia do Hospital de Reabilitação de Anomalias Craniofaciais (HRAC/USP) atua em conjunto com a equipe multidisciplinar tanto no ambulatório quanto nas unidades de internação, onde realiza terapia respiratória para melhora do quadro clínico e condição cirúrgica desses pacientes. Diversas são as técnicas de fisioterapia respiratória utilizadas, sendo necessária uma modificação ou adaptação para melhor realização no paciente fissurado. Objetivo: Descrever e divulgar as rotinas de atendimento fisioterapêutico respiratório do Setor de Fisioterapia do HRAC/USP. Método: Baseado em um estudo descritivo da experiência clínica. Resultados: Realiza-se primeiramente uma anamnese, após verifica-se exames laboratoriais e de imagem seguindo para uma avaliação fisioterapêutica respiratória e assim são traçadas as condutas necessárias com o paciente. Na Unidade Ambulatorial foi observado que os pacientes ganham condição cirúrgica após realização de terapia respiratória pré operatória. Na Unidade de Internação a Fisioterapia auxilia na diminuição do tempo de hospitalização, orientando acompanhantes à continuidade do tratamento em casa. Conclusão: Acredita-se que o presente estudo possa contribuir para a divulgação da atuação do fisioterapeuta na assistência de pacientes com fissuras labiopalatinas.

Multiple trichoblastomas in a dog

Background – Hair follicle tumours generally present as benign, solitary masses and have a good prognosis following surgical resection. Hypothesis/Objectives – This report describes a case of multiple trichoblastomas in a dog. Animal – A 2-year-old crossbred dog presented with multiple soft cutaneous periocular, perilabial, submandibular and nasal nodules, between 2 and 9 cm in diameter, located on the right side of the face. New nodules were observed on the same side of the face at a second consultation 3 weeks later. Methods – Surgical resection of all nodules was performed in two procedures. Three nodules were initially resected and submitted for histolopathology and immunohistochemistry. The diagnosis was trichoblastoma for all three. At the time of the second consultation, new and remaining nodules were biopsied and the diagnosis of trichoblastoma confirmed. The dog was treated with doxorubicin and piroxicam for 30 days prior to the second surgical procedure in an attempt to reduce new tumour growth and the size of present tumours. All nodules were resected and the defects closed using rotation flaps. Results – No recurrence of the neoplasm was noted within 10 months after surgery. Conclusions and clinical importance – Trichoblastomas are generally benign but can present as multiple neoplasms that may require surgical resection and may respond to chemotherapy. To the authors’ knowledge, this is the first report of multiple trichoblastomas in a dog.
