Patología infecciosa del vestíbulo nasal / Infectious diseases of the nasal vestibule

El vestíbulo nasal corresponde a la primera porción de la fosa nasal, éste se encuentra delimitado lateralmente por los cartílagos alares y medialmente por el borde caudal del septum nasal y la columela. Las enfermedades infecciosas del vestíbulo nasal son patologías frecuentes en la práctica clínica; su diagnóstico se realiza en base a sospecha clínica y examen físico, requiriendo habitualmente solo manejo médico ambulatorio. Desde el punto de vista etiológico pueden ser virales, bacterianas y fúngicas. Las principales especies bacterianas involucradas corresponden a Staphylococcus coagulasa negativa, S. epidermidis, S. hominis y S. haemolyticus, difteroides spp y S. aureus. Su manejo es esencialmente médico con casos excepcionales requiriendo manejo quirúrgico. En la actualidad existe escasa información epidemiológica al respecto, lo que dificultad la clasificación de los dichos cuadros clínicos. Se realizó una revisión de la literatura sobre cuadros infecciosos que afectan el vestíbulo nasal para lograr sistematizar y clarificar las distintas patologías y sus tratamientos.

The nasal vestibule corresponds to the first portion of the nasal passage, limited laterally by the lateral crus and medially by the caudal edge of the nasal septum and columella. Infectious diseases of the nasal vestibule are frequent in clinical practice, diagnosis is made based on clinical suspicion and physical examination, usually requiring only ambulatory medical management. In terms of etiology, they can be viral, bacterial and fungal. The main bacterial species involved correspond: Coagulase-negative Staphylococcus, S. epidermidis, S. hominis and S. haemolyticus, difteroides spp and S. aureus. Management is essentially medical and only exceptionally requires surgery. Currently, there is a lack of epidemiological information in this regard, which makes it difficult to classify these clinical conditions. A review of the literature on infectious conditions that affect the nasal vestibule was performed, to systematize and clarify the different pathologies and their management.

Voz hipernasal y regurgitación nasal aguda: reporte de un caso clínico y revisión de la literatura / Hypernasal speech and acute nasal regurgitation: a case report and a review of the literature

RESUMEN La voz hipernasal y la regurgitación nasal son síntomas de disfunción velofaríngea. Ésta puede tener múltiples causas: anatómicas, neurológicas o funcionales. Se describe el caso de una paciente de sexo femenino, de 13 años, que se presenta con voz hipernasal y regurgitación nasal aguda. Al examen físico se evidencia inmovilidad del velo del paladar derecho sin otros hallazgos neurológicos. El estudio con resonancia nuclear magnética de cerebro y punción lumbar fueron normales. Se diagnosticó una incompetencia velofaríngea aguda transitoria, de probable etiología viral. La paciente evolucionó de forma favorable con mejoría clínica progresiva. La incompetencia velofaríngea a causa de una paresia o parálisis del nervio vago y/o nervio glosofaríngeo es una causa poco frecuente de disfunción velofaríngea.

ABSTRACT Hypernasal speech and nasal regurgitation are symptoms of velopharyngeal dysfunction. This may have multiple causes, including velopharyngeal incompetence due to paresis or paralysis of the vagus nerve and/or glossopharyngeal nerve. We describe the case of a 13 year-old female patient, with hypernasal speech and acute nasal regurgitation, with a physical examination showing immobility of the right palate with no other neurological findings. Magnetic resonance imaging of the brain and lumbar puncture was normal. Transient acute velopharyngeal incompetence was diagnosed, probably of viral etiology. The patient evolved favorably with progressive clinical improvement. Velopharyngeal incompetence due to paresis or paralysis of the vagus and/or glossopharyngeal nerves is a rare cause of velopharyngeal dysfunction.

Clinical significance of ocular manifestations in granulomatosis with polyangiitis: association with sinonasal involvement and damage.

Ocular involvement is present in 50-60% of granulomatosis with polyangiitis (GPA) patients and can affect any part of the ocular globe. The present study describes ophthalmologic manifestations, association with systemic symptoms, disease activity and damage in GPA. A cross-sectional study was conducted including patients with GPA who underwent rheumatologic and ophthalmologic evaluation. Demographics, comorbidities, ophthalmologic symptoms, serologic markers, radiographic studies, disease activity and damage were assessed. Descriptive statistics, correlation, univariable logistic regression analyses, Student's t, Mann-Whitney U, Chi-square and Fisher's exact tests were performed. Fifty patients were included, 60% female, the median age was 56 years, disease duration 72.5 months. Nineteen (38%) patients had ocular manifestations at GPA diagnosis, scleritis being the most frequent; 27 (54%) patients presented ocular involvement during follow-up, repeated scleritis and dacryocystitis being the most common manifestations. Concomitant ophthalmic and sinonasal involvement was present in 12 (24%). Ocular and ENT damage occurred in 58% and 70%, respectively. Epiphora and blurred vision were the most frequent symptoms; scleromalacia and conjunctival hyperemia (27%) the most frequent clinical abnormalities. Ocular involvement at diagnosis was associated with concomitant ocular and sinonasal involvement at follow-up (OR 4.72, 95% CI 1.17-19.01, p = 0.01). Ocular involvement at follow-up was associated with age at GPA diagnosis (OR 0.94, 95% CI 0.90-0.99, p = 0.03), VDI (OR 1.29, 95% CI 1.03-1.61, p = 0.02), and ENT damage (OR 5.27, 95% CI 1.37-20.13, p = 0.01). In GPA, ocular involvement is frequent, therefore, non-ophthalmologist clinicians should be aware of this manifestation to reduce the risk of visual morbidity and organ damage.

Calcinosis tumoral en septum nasal en un paciente con insuficiencia renal crónica dializado. Presentación de un caso / Tumoral calcinosis in nasal septum in a patient with chronic renal failure in dialysis. Presentation of a case

Los trastornos metabólicos ocasionados por la insuficiencia renal y la diálisis para su tratamiento pueden conducir a la precipitación de sales de fosfato cálcico con la consecuente formación de tumores en diversas localizaciones. Estos pueden ser únicos o múltiples, pudiendo ocasionar obstrucción y compresión de distintas estructuras anatómicas con la consecuente alteración funcional. Si bien el manejo clínico de las alteraciones antes citadas es fundamental, la cirugía adquiere relevancia en estas situaciones. Se presenta un caso de Calcinosis Tumoral única ubicada en el tercio anterior del septum nasal, ocasionando obstrucción de la fosa nasal. La tomografía computada orientó el diagnóstico y la resección tumoral completa por vía nasal fue el tratamiento elegido. El informe de anatomía patológica confirma el diagnóstico de Calcinosis Tumoral. A los nueve meses de seguimiento en el postoperatorio no se evidencia recidiva.

Metabolic disorders caused by chronic renal failure and dialysis for its treatment can lead to the precipitation of calcium phosphate salts with the consequent formation of tumors in various locations. These can be single or multiple, and may cause obstruction and compression of different anatomical structures with consequent functional alteration. Although the clinical management of the above mentioned alterations is fundamental, the surgery acquires relevance in these situations. We present a case of unique tumoral calcinosis located in the anterior third of the nasal septum, causing obstruction of the nasal fossa. Computed tomography guided diagnosis and complete tumor resection by nasal route was the treatment chosen. The pathological anatomy report confirms the diagnosis of tumor calcinosis. At nine months post-operative follow-up there was no evidence of tumor recurrence.

Nasal Skin Necrosis: An Unexpected New Finding in Severe Chikungunya Fever.

Three adult Venezuelan patients with virologically confirmed Chikungunya fever, who developed extensive acute nasal skin necrosis early in the course of a life-threatening illness characterized by shock and multiple organ dysfunction syndrome, are discussed. One patient survived and fully recovered. Nasal necrosis has not previously been associated with the disease.

Piercings en cabeza y cuello / Head and neck piercings

Los piercings corporales son una práctica habitual en la sociedad actual, y consisten en la perforación de un tejido para insertar un aro u otro elemento ornamental. Este procedimiento implica la creación de una puerta de entrada cutánea o mucosa que puede permitir el ingreso de microorganismos, además de la posible formación de cicatrices anómalas. Asimismo, el aro puede predisponer a otras complicaciones como reacciones de hipersensibilidad, desplazamientos o aspiración. Debido a esta amplia gama de posibles complicaciones, los piercings debieran realizarse en establecimientos autorizados, por personal entrenado y bajo técnica aséptica. El personal médico debe conocer el diagnóstico y manejo de estas complicaciones, y dado que la mayoría de las perforaciones se realizan en el área de cabeza y cuello, el otorrinolaringólogo debiera estar especialmente familiarizado con los aspectos médicos de ésta práctica.

Body piercing is considered a normal practice in today's society. It consists in the perforation of corporal tissue to insert a ring or other ornamental object with an esthetic purpose. This procedure implicates the creation of a cutaneous or mucosal entry point that could allow pathogenic microorganisms into the body, and could also promote the formation of anomalous scar tissue. Other complications, such as hypersensitivity reactions, displacement and aspiration, have been reported. Due to this wide range of possible complications, body piercings should be performed only in authorized establishments, by trained staff and under supervised aseptic technique. Health care providers should be aware about the diagnosis and treatment of these complications. Given that most piercings are placed in the head and neck area, otolaryngologists should be especially familiarized with the medical aspects of this practice.

Mucociliary clearance, airway inflammation and nasal symptoms in urban motorcyclists.

OBJECTIVES: There is evidence that outdoor workers exposed to high levels of air pollution exhibit airway inflammation and increased airway symptoms. We hypothesized that these workers would experience increased airway symptoms and decreased nasal mucociliary clearance associated with their exposure to air pollution. METHODS: In total, 25 non-smoking commercial motorcyclists, aged 18-44 years, were included in this study. These drivers work 8-12 hours per day, 5 days per week, driving on urban streets. Nasal mucociliary clearance was measured by the saccharine transit test; airway acidification was measured by assessing the pH of exhaled breath condensate; and airway symptoms were measured by the Sino-nasal Outcome Test-20 questionnaire. To assess personal air pollution exposure, the subjects used a passive-diffusion nitrogen dioxide (NO2) concentration-monitoring system during the 14 days before each assessment. The associations between NO2 and the airway outcomes were analyzed using the Mann-Whitney test and the Chi-Square test. Clinicaltrials.gov: NCT01976039. RESULTS: Compared with clearance in healthy adult males, mucociliary clearance was decreased in 32% of the motorcyclists. Additionally, 64% of the motorcyclists had airway acidification and 92% experienced airway symptoms. The median personal NO2 exposure level was 75 mg/m3 for these subjects and a significant association was observed between NO2 and impaired mucociliary clearance (p=0.036). CONCLUSION: Non-smoking commercial motorcyclists exhibit increased airway symptoms and airway acidification as well as decreased nasal mucociliary clearance, all of which are significantly associated with the amount of exposure to air pollution.

Two-flap palatoplasty for treatment of oronasal fistula by trauma sequel.

The oronasal fistula is a chronic communication between the oral and nasal cavity that often affects patients with cleft palate. However, others uncommon causes of oronasal fistula are associated with facial traumas, infections and neoplasias. In this report we present a case of oronasal fistula as consequence of facial trauma that was treated by two flaps technique for palatoplasty. In this sense, we discussed treatment indications, surgical technique and patient prognostic of a relatively simple option that can provide a definitive repair with minimal morbidity.

Utilidad del botón septal y nivel de satisfacción obtenido en los pacientes con perforaciones del septum: nuestra experiencia / Septal button utility and level of satisfaction obtained in patients with drilling septal: our experience

Introducción: La mayoría de las perforaciones septales suelen ser asintomáticas, aunque algunas pueden presentar una rinitis costrosa, obstrucción nasal, epistaxis recidivante o sibilancias nasales. Su origen es sobre todo iatrogénico o idiopático, pero también podemos encontrar otras causas. Los botones septales constituyen una solución útil por la sencillez de su colocación, siendo de elección en pacientes que no deseen una intervención quirúrgica más compleja. Objetivo: Conocer las características de las perforaciones septales, además de, realizar un estudio sobre los resultados obtenidos en la cirugía de botón septal y el nivel de satisfacción obtenido por los pacientes tras esta intervención. Material y método: Análisis retrospectivo de 22 pacientes intervenidos quirúrgicamente de colocación de botón septal entre enero de 2008 a agosto 2010 en el Hospital Clínico Universitario Lozano Blesa de Zaragoza. El análisis incluye un estudio sobre la etiología, tamaño y sintomatologia de dichas perforaciones candidatas a la utilización del botón septal. Además del análisis de la presencia o ausencia de complicaciones tras la cirugía, la evolución y la mejoría o empeoramiento posoperatorio, en cuanto a los cinco síntomas principales; obstrucción nasal, las sibilancias, las costras endonasales con sequedad, la epistaxis y la rinorrea con tres posibles respuestas; igual, mejor o peor. En el consultorio y a los tres meses de la intervención, se realiza una encuesta con una escala analógica visual (EVA), en la que el paciente realiza una puntuación subjetiva del 1 al 10 para valorar su nivel de satisfacción tras la colocación del obturador Por último se le pregunta si volvería a ponérselo. Los resultados no fueron analizados con pruebas estadísticas dado el pequeño tamaño muestral. Resultados: Nuestros pacientes han presentado una importante mejoría en síntomas como la obstrucción nasal...

Introduction: Most of the septal perforations are usually asymptomatic, although some may have a crusty rhinitis, nasal obstruction, recurrent epistaxis or nasal wheeze. Its origin is mostly iatrogenic or idiopathic but can also find other causes. Septal buttons are a useful solution for the simplicity of their placement, being of choice in patients who do not want surgery more complex. Aim: Knowing the characteristics of septal perforations, in addition, a study on the results of septal button surgery and the level of satisfaction obtained by patients after the intervention. Material and method: Retrospective analysis of 22 patients with surgical septal button surgical placement between January 2008 to August 2010 at the Hospital Clinico Universitario Lozano Blesa from Zaragoza. The analysis includes a study on the etiology, symptoms of such size and drilling candidates for the use of septal button. Besides the analysis of the presence or absence of complications after surgery, and postoperative improvement or worsening in the five main symptoms, stuffy, nose, wheezing, endonasal crust with dryness, epistaxis and rhinorrhea with three possible answers, same, better or worse. Three months after surgery in the office is conducting a survey with a visual analogue scale (VAS), in which the patient makes a subjective score of 1 to 10 to assess their level of satisfaction after the placement of the shutter. Finally asked if he would wear it. The results were analyzed with statistical tests given the small sample size. Results: Our patients have experienced a significant improvement in symptoms such as nasal obstruction and wheezing. Nasal dryness has been with worse clinical outcomes after placement of the button. Subjectively 77.2(0) percent of patients would put him back. Conclusions: The septal buttons are a therapeutic tool to keep in mind for the closure of septal perforations with good results in patients unsuitable for surgical correction.

Mucormicosis en una paciente diabética: caso clínico y revisión de la literatura / Mucormycosis in a diabetic patient: case report and literature review

Presentamos un caso de Mucormicosis Rinoorbitaria en una mujer de 48 años, diabética, en cetoacidosis, a quien se hizo el diagnóstico por histopatología. Tratada con anfotericina B intravenosa y un agresivo debridamiento quirúrgico para eliminar tejidos infartados y necróticos de gran parte de la hemicara y ojo derecho, logra sobrevivir a esta catastrófica infección. La mucormicosis es una infección aguda y extremadamente grave causada por hongos oportunistas y ubicuos del orden Mucoroles pertenecientes a la clase Phycomycetes, que afecta principalmente a un grupo de pacientes cuyas condiciones inmunológicas y metabólicas favorecen el desarrollo del hongo. Hacemos una definición del grupo de "pacientes en riesgo", lo que es extremadamente importante, ya que de la sospecha clínica se puede abordar un diagnóstico precoz para evitar la alta mortalidad y morbilidad que esta enfermedad provoca. Analizamos la patogenia de la enfermedad, así como una revisión de la literatura sobre modalidades de diagnóstico y terapéutica. El diagnóstico de urgencia sigue siendo de responsabilidad del patólogo, y el tratamiento de mayor éxito es la anfotericina B.

We present a case of rhinoorbital mucormycosis in a diabetic, developing ketoacidose, 48-year old woman. Diagnosis was established through histopathology. The patient was successfully treated and survives with a combination of anphotericin B and an aggressive surgery in order to eliminate all the ischemic and necrotic tissues affecting almost the entire right side of the face and intraorbital structures surviving to this catastrophic infection. Mucormycosis is an acute and often fatal infection caused by opportunistic fungus of the class Zygomycetes, order Mucoroles that affects a select group of patients associated with underlying metabolic and immunological disorders. A definition of "risk-group" is proposed. This definition is of extreme importance for a prompt diagnosis avoiding the high rate of morbidity and mortality associated with this condition. We review both pathogenic mechanism and literature related to diagnostic modalities and new therapeutical approaches. Emergency diagnosis is still in hands of pathologists and the most successful treatment is with anphotericin B.

[Mucosal complication of cutaneous leishmaniasis]. / Complicación mucosa de la leishmaniasis cutánea.

A 74-year-old man from the rural area of Caicedonia, Valle del Cauca Province, was diagnosed with uncontrolled hypertension, stage IV chronic renal failure and severe anemia. Fifteen years earlier, while living in Guaviare Province, he was diagnosed with leishmaniasis-with lesions located on the right upper and lower eyelids, left auricle and limbs. At that time, he received an incomplete treatment with antimonials. The patient had experienced 8 years of progressive mucosal lesions located in the upper lip, nasal mucosa and right upper and lower eyelids (figure 1). A histopathological diagnosis of leishmaniasis was made and confirmed by polymerase chain reaction (figure 2). Treatment with antimonials (Glucantime) was contraindicated due to the patient's comorbidities. Inpatient supervised treatment with miltefosine (Impavido 50 mg capsules) was initiated according to the national guidelines of 1.8 mg/kg/day for 28 days. Clinical follow up and routine laboratory tests (creatinine, BUN, liver function tests and complete blood counts) were done during and after treatment; no complications were reported. Medical follow up was continued until the Internal medicine, ophthalmology, and plastic surgery consultations were provided for subsequent management of the pathology. Mucocutaneous leishmaniasis is a serious preventable complication of cutaneous leishmaniasis. This case illustrated a failure in opportune diagnosis and treatment of this disease as a consequence of an inadequate leishmaniasis control program. The case indicated the effectiveness of miltefosine as a therapeutic option in patients for whom antimonial treatment is contraindicated.

Oronasal complications in patients after transsphenoidal hypophyseal surgery.

Transsphenoidal surgery is the most commonly used surgical procedure to handle the hypophyseal region, sometimes associated with oronasal complications. MATERIAL AND METHODS/AIM: To evaluate prospectively (specific questionnaire, clinical evaluation) undiagnosed chronic oronasal complications in patients submitted to conventional transsphenoidal adenomectomy surgery, operated at different neurosurgery services more than 6 months ago. RESULTS: 49 patients were evaluated, 37/45 presented macroadenoma. 28,5% were submitted to more than one intervention, 2/5 transsphenoidally. Transsphenoidal approach 92.8% through sublabial route. No patient had spontaneous complaint. With the specific questionnaire 63.2% presented complaints. One patient presented an oronasal fistula, 1 stenosis of the nasal valve area with external nasal deformity. Rhinoscopy detected alterations in 77.5%, nasal endoscopy in 87.7%. Septal perforation was present in 10/12 patients with scabs and 2 with purulent secretion. All 4 patients submitted to 2 transsphenoidal approaches presented septal perforation and nasal synechiae. In the endonasal, synechiae (2), alteration in medium meatus (1) and stenosis of the nasal valve area (1) were observed. Only two patients presented normal evaluation. CONCLUSION: A high incidence of nasal complications after conventional transsphenoidal surgery observed through examination and not reported spontaneously point to the need of otorhinolaryngological investigation complemented by nasal endoscopy in patients submitted to procedures through this route.

A cirurgia transesfenoidal é o procedimento cirúrgico mais utilizado para abordagem da região hipofisária, sendo por vezes associada a complicações oronasais. MATERIAL E MÉTODOS/OBJETIVO: Estudo prospectivo, através de questionário específico e avaliação clínica complicações oronasais crônicas não-diagnosticadas, em pacientes submetidos à cirurgia transesfenoidal convencional em diferentes serviços de neurocirurgia há mais de 6 meses. RESULTADOS: 49 pacientes, 37/45 com macroadenoma. 14/49 submetidos a mais de uma intervenção, em 2/5 por via transesfenoidal. Abordagem transesfenoidal 92,8 por cento via sublabial. Nenhum apresentava queixa espontânea. Com o questionário específico, 63,2 por cento apresentaram queixas. Um apresentava fístula oronasal, outro, estenose da área de válvula nasal com deformidade nasal externa. A rinoscopia detectou alterações em 77,5 por cento e a endoscopia nasal em 87,7 por cento. Perfuração septal presente em 10/12 pacientes com crostas e 2 com secreção purulenta. Todos 4 pacientes submetidos a 2 abordagens transesfenoidais apresentaram perfuração do septo e sinéquias nasais. Nos casos com abordagem endonasal observaram-se sinéquias2, alteração em meato médio1 e estenose em área de válvula nasal1. Apenas 2 pacientes apresentaram avaliação normal. CONCLUSÃO: Alta incidência de complicações nasais após abordagem transesfenoidal convencional, observadas (exame) e não referidas espontaneamente indicam a necessidad de investigação otorrinolaringológica complementada com endoscopia nasal sistemática nestes pacientes.

Immediate dental implant failure associated with nasopalatine duct cyst.

This case report presents an analysis of the clinical, radiographic, and histological features of a peri-implant lesion around an implant placed immediately after extraction of a tooth with a periapical lesion. A 52-year-old man received an immediate implant (3.75 x 11.5 mm2) placed in the anterior region of the maxilla. Three years after implant placement, the patient presented with swelling in the anterior portion of the maxilla. Radiographic examination showed a well-circumscribed radiolucency around the implant. The implant and the lesion were removed and fixed in 10% buffered formalin and processed. Histological analysis showed 3 types of epithelium: respiratory, cuboidal, and non-keratinized stratified squamous. In the cyst wall peripheral nerves, arteries, veins, and chronic inflammation were present. The diagnosis was nasopalatine duct cyst. We concluded that the nasopalatine duct cyst can develop in association with dental implants. Clinically, the lesion is similar to the classical nasopalatine duct cyst. Histological analysis should be mandatory in all cases of peri-implant lesions and in all dental periapical lesions before immediate implant placement.

Cutaneous and nasal protothecosis in a goat.

A case of protothecosis is reported in an adult goat with inspiratory dyspnea and stertor. Dermatitis with prominent ulcerated nodules up to 3 cm in diameter was observed in the muzzle at the mucocutaneous junctions of nasal and lip skin, and in the border of the pinna. Histologic lesions were necrotizing pyogranulomatous dermatitis and rhinitis with myriads of walled sporangia, characteristic of Prototheca wickerhamii. This seems to be the first report of protothecosis in a goat.

[A case of a child with bad odor]. / El caso de una niña maloliente.

The odor emitted by a patient may be one of the first major clues leading to an early diagnosis. Certain conditions produce a characteristic smell and several diseases are associated with a specific odor. We report an illustrative case and review olfactory physiology, the value of smell in physical examination, and finally discuss several illnesses associated with unusual odors.

[A fatal case of mucocutaneous leishmaniasis after pentavalent antimonial use]. / Obito em caso de leishmaniose cutâneomucosa após o uso de antimonial pentavalente.

The authors report a case of mucocutaneous leishmaniasis in a 45-year-old patient who was unsuccessfully treated with pentavalent antimonial for 30 days. After 10 days from the initial treatment and before starting a new therapeutic regimen with the same drug the patient died due to sudden cardiac arrest.

Nasal septum giant pyogenic granuloma after a long lasting nasal intubation: case report.

The authors present a case of Pyogenic Granuloma (PG) arising from the nasal septum in the posterior nasal cavity of a patient male sex, caucasian, 32 years old, with a previous history of cranioencephalic trauma, several neurosurgeries for different subsequent neurological problems and the use of a nasogastric tube for feeding (nasal intubation) during 30 days. He underwent surgery in St. Vincent de Paul Hospital (Rio de Janeiro) on May 18, 1993, for the tumor removal and straightening of the nasal septum. Under endoscopic guidance the complete excision of the tumor mass was perfectly done thanks to the excellent exposure of the lesion, provided by the enlarged telescopic view, and the wide access afforded by the septum straighttening plus the cartilaginous septum mobilization through the maxilla-premaxilla approach of Cottle, allied to the lateralization and volume reduction of the right inferior nasal concha, simultaneously performed, thus making lateral rhinotomy or "degloving" unnecessary. The patient is until now (2004) completely free of the lesion operated on. This is the first report in the literature of such a lesion associated to nasal intubation as the triggering agent.
