Validación de un cuestionario específico de calidad de vida en sialoadenitis obstructiva crónica (CSOC) / Validation of a Spanish chronic obstructive sialadenitis quality of life questionnaire (CSOC)

Antecedentes y objetivos: El interés en la sialoadenitis obstructiva crónica está aumentando con la introducción de la sialoendoscopia. Es necesario contar con un instrumento para evaluar la calidad de vida en los pacientes con sialoadenitis obstructiva crónica que permita mejorar el manejo clínico y apoyar la investigación. Los objetivos del presente trabajo son diseñar un cuestionario en español para evaluar la calidad de vida en los pacientes con sialoadenitis obstructiva crónica, denominado CSOC, y evaluar su fiabilidad, validez y viabilidad.Material y métodosEstudio prospectivo, multicéntrico, observacional, en el que se incluyeron pacientes con diagnóstico de sialoadenitis obstructiva crónica. Se realizaron una búsqueda bibliográfica y entrevistas con pacientes para la generación de las preguntas del cuestionario. A continuación, un panel de expertos evaluó la validez de contenido. La validez de constructo fue evaluada en una muestra de 120 pacientes y 100 controles. Los pacientes contestaron un CSOC, un short form-36 (SF-36) versión en español y una escala visual analógica (EVA). Se evaluó la viabilidad, la fiabilidad, la consistencia interna, la validez de constructo y la sensibilidad al cambio.ResultadosTodos los pacientes encontraron comprensible el instrumento. El tiempo requerido para completar el CSOC pre y postsialoendoscopia fue de 5,7 y 4,5min, respectivamente. El coeficiente α de Cronbach fue muy alto para el CSOC pre y postsialoendoscópico (0,90 y 0,94, respectivamente). La correlación con las dimensiones del SF-36 fue negativa y positiva con la EVA. La puntuación media del CSOC en el grupo con sialoadenitis fue de 28,63 (antes de la sialoendoscopia) y de 8,33 (después de la sialoendoscopia). En el grupo control la puntuación media del CSOC fue de 1,31.ConclusionesEl CSOC es comprensible, factible, fiable y representativo de la calidad de vida en pacientes con sialoadenitis obstructiva crónica.

Background and objectives: Interest in chronic obstructive sialadenitis is increasing with the introduction of sialendoscopy. A self-administered instrument to assess quality of life in patients with chronic obstructive sialadenitis is needed to improve clinical management and support research. The objectives of this study are to design a Spanish questionnaire to assess quality of life in chronic obstructive sialadenitis, named CSOC and assess its reliability, validity and feasibility.Material and methodsA prospective, multicentre, observational study was conducted. Patients with diagnosis of chronic obstructive sialadenitis were included in the study. The item generation process included a review of published data as well as interviews with patients.

Chronic Obstructive Sialadenitis due to an Abnormal Wharton's Duct Draining to the Tonsillar Fossa.

INTRODUCTION: Chronic obstructive sialadenitis (COS) is an entity that causes a marked loss in patient quality of life, including changes in eating habits and a progressive loss of gland function. It is characterized by repeated episodes of painful glandular swelling often requiring emergency care. There are multiple causes of COS, including lithiasis, strictures, anatomical variants, and others. The development of specific imaging tests such as magnetic resonance (MR) sialography or sialendoscopy have increased knowledge of these obstructions and how to specifically treat them. CASE SUMMARY: We present an unusual case of a woman with a years-long history of chronic obstructive sialadenitis in which an abnormal path of Wharton's duct was in evidence. This duct, which was atrophic and smaller in diameter, opened in the tonsillar fossa rather than lateral to the lingual frenulum. This case, the first in vivo description of its kind, was confirmed by MR sialography and sialendoscopy. DISCUSSION: Congenital anomalies of the submandibular duct are a rare finding, but may cause COS. Therefore, COS requires a detailed diagnostic study, usually by ultrasound, MR sialography and sialendoscopy, to rule out complex anatomical variants.

Sialolithiasis: mineralogical composition, crystalline structure, calculus site, and epidemiological features.

The purpose of this paper was to describe the characteristics of salivary calculi and their relationship to epidemiological factors, through a cross-sectional study. We analysed 100 calculi obtained in 2017-2021. Patient data including age, time since onset of symptoms, gland involved, and site of location in the salivary system were studied. The calculi were studied to determine their morphological features using scanning electron microscopy and energy dispersive plain radiographic analysis. Most of the calculi had formed in the submandibular gland (SG) (82%). The mean age of patients at onset was 45.83 years; patients presenting parotid gland (PG) stones were somewhat older (p = 0.031). The mean time since the onset of symptoms was longer in PG calculi (p = 0.038). The most common lithiasis site was the main duct (74%), followed by the hilum (22%). Hilar stones were the largest (p < 0.05) and heaviest (p = 0.028). Octacalcium phosphate (OCP) was the most common crystalline phase (Cp) founded, followed by hydroxyapatite (HA) and whitlockite (WH). Specifically, OCP had a higher presence in PG calculi (p = 0.029) and WH was the most common phase in SG calculi (p = 0.017). The most prevalent site of lithiasis was the main duct, and the largest and heaviest calculi were found in the SG. PG stones were associated with a longer history of symptoms and older age. OCP was the most frequent Cp of the calculi studied, and the main Cp in PG stones. WH was the predominant Cp in SG stones. The Cp of the calculi was not influenced by location, patient age, or time of symptoms.

p16 Influence on Laryngeal Squamous Cell Carcinoma Relapse and Survival.

OBJECTIVE: (1) To identify p16 protein in laryngeal squamous cell carcinoma (LSCC) specimens and to correlate it with the presence of human papillomavirus (HPV) found in these specimens from a previous study. (2) To analyze p16 impact on 10-year overall and disease-free survival. STUDY DESIGN: Retrospective case series with oncologic database chart review. SETTING: Academic tertiary care hospital. SUBJECTS: A total of 123 samples of LSCC (taken from the glottis only) from patients treated with primary surgical resection between 1977 and 2005. METHODS: p16 protein expression was analyzed through immunohistochemistry and compared with the presence of HPV established in our previous studies. Results were compared with histologic, clinicopathologic, and survival parameters, with a 10-year follow-up. RESULTS: Of the samples, 39.02% were positive for p16, but only 11.38% were positive for both p16 and HPV. The p16+ cohort showed a significant improvement in disease-free survival ( P = .0022); statistical significance was not achieved for overall survival. p16+ cases had fewer relapses over time, with no relapses after a 2-year follow-up. Age at the time of diagnosis and tobacco consumption were the only epidemiologic factors that influenced overall survival. CONCLUSION: The expression of p16 protein was a beneficial prognostic factor for disease-free survival among patients with LSCC of the glottis, with no relapses after a 2-year follow-up.

Microscopic approach for repairing nasal septal perforations using bilateral advancement flaps.

BACKGROUND: Septal perforations consist in an anatomic defect of the mucosal, cartilaginous and/or bone tissues of the nasal septum. A huge variety of approaches and techniques for nasal perforation repair have been reported. METHODOLOGY/PRINCIPAL: Between January 2008 and January 2017, 38 patients were treated for nasal septal perforation in Department of Otorhinolaryngology Head and Neck Surgery, Fundación Jiménez Díaz University Hospital, Madrid, Spain. A novel approach is presented based on microscope. Septal perforation closure was performed with endonasal bilateral advancement flaps-established technique and autologous cartilage and muscle temporal fascia grafts. We performed a retrospective review of closure rates and complications. RESULTS: A postoperative follow-up of at least 12 months was performed in 37 patients. The mean size of perforation was 1.33 cm. After the withdrawal of the silicone splints, perforations were completely closed in all cases. However, during the follow-up, four patients resulted in a reperforation, so our closure rate was 89.19%. For all cases, symptoms related to septal defect were solved. Only one case was reported of local infections that was resolved with antibiotics in a few days. CONCLUSIONS: Microscopic approach of septal perforation closure using bilateral advancement flaps can be an affordable technique with a high percent of success and low rate of complications.
