Bilateral parotid gland swelling: An unusual presentation of B cell lymphoma.

ABSTRACT: This case report describes a 45-year-old woman with acute, bilateral parotid gland swelling caused by B-cell lymphoma. Enlarged, tender salivary glands are more commonly caused by infection, inflammation, or obstruction from salivary gland stones or tumors. This patient initially was treated for common causes of parotitis; however, her condition did not respond to the standard management and she ultimately was diagnosed with B-cell lymphoma.

Differences between radioactive iodine-induced sialadenitis and chronic obstructive parotitis.

The purpose of this study was to clarify the differences in the diagnosis and treatment outcomes between radioactive iodine-induced sialadenitis (RAIS) and chronic obstructive parotitis (COP). The study cohort comprised 47 consecutive patients diagnosed with RAIS and 50 patients with COP. All patients were treated by interventional endoscopy. Clinical, sialography, and endoscopy characteristics and treatment outcomes were compared between the two groups. Compared with the COP group, the RAIS group included more females (male:female ratio 1:8.4 vs 1:2.1; P = 0.011) and had a younger onset age (42 vs 50 years; P = 0.001) and shorter disease duration prior to hospital visit (5.4 vs 34.8 months; P < 0.001). In the RAIS group, sialography revealed obliteration of the main duct (20.4% vs 0%; P < 0.001), non-visualization of the main gland (23.7% vs 0%; P < 0.001), and incomplete contrast filling of the main gland (19.4% vs 6.4%; P = 0.008), which were scarcely observed in the COP group. Endoscopy revealed a higher percentage of duct atresia in RAIS compared to COP (20.4% vs 0%; P < 0.001). During follow-up, a higher percentage of RAIS patients had duct atresia and gland atrophy (49.5% vs 1.1%, P < 0.001). Compared with COP, RAIS more commonly involves younger females and has a shorter disease duration. Atresia of the main duct and atrophy of the gland parenchyma occur more often despite the use of interventional endoscopy.

Conservative Management of Chronic Suppurative Parotitis in Patients with Sjögren Syndrome: A Case Series.

BACKGROUND Parotitis is an inflammation of the parotid gland, which can be caused by factors including infection, radiation, and hyposalivation secondary to systemic conditions, such as Sjögren syndrome, rheumatoid arthritis, or medication. Bacterial parotitis is a rare complication that can be observed in patients with hyposalivation. However, it is also observed in elderly and immunocompromised patients. Lack of continuous flushing of salivary glands and their ducts due to decreased salivary flow renders the glands prone to retrograde colonization with oral microflora. Several microorganisms have been associated with bacterial infections of the parotid glands; Staphylococcus aureus is the most common, accounting for 80% of cases, followed by mixed bacterial communities, including streptococci, anaerobes, and gram-negative bacilli. Bacterial parotitis presents as tenderness, swelling, and purulent sialorrhea from the salivary gland's duct. Immediate administration of broad-spectrum antibiotics, based on the results of the patient's culture and sensitivity test, has shown success in treating these cases. CASE REPORT We report 3 cases of chronic suppurative parotitis secondary to dry mouth and due to Sjögren syndrome that did not respond to oral or intravenous antibiotics and was successfully managed using conservative methods, such as the local application of superficial moist heat and periodic pus drainage by manipulating the parotid glands at dental clinics. CONCLUSIONS We concluded that conservative approaches, such as massaging the glands, local application of superficial moist heat, and periodic pus drainage without using antibiotics, should be considered as the first-line management of bacterial infection of the parotid glands.

Otorrhoea - a parotid connection.

SUMMARY: A 36-year-old patient presented with an 18-month history of intermittent right parotid swelling accompanied by otorrhoea. The symptoms started subsequent to a palm leaf injury to the right ear. At right parotidectomy, a fistula connecting the right external auditory canal and the right parotid was demonstrated. A small fibrotic mass probably due to a remnant of the palm leaf was found intraoperatively. The symptoms resolved completely after the mass was excised by superficial parotidectomy, and the fistula closed spontaneously.

Sjögren's syndrome in children with recurrent parotitis.

OBJECTIVE: Optimize the diagnosis of pediatric Sjögren's syndrome in children who present with parotitis. METHODS: Twenty children presented to a pediatric otolaryngology or rheumatology clinic with recurrent parotitis. Presenting symptoms, serologies, sialendoscopy findings, and minor salivary gland biopsy pathology results were reviewed. RESULTS: Twenty patients aged 3-17 years presented with recurrent parotitis. Ten percent of this cohort met the American-European Consensus Group adult diagnostic criteria for Sjögren's syndrome. Forty percent of this cohort met diagnosis of Sjögren's syndrome when utilizing Bartunkova's proposed pediatric criteria for diagnosis of Sjögren's syndrome. CONCLUSION: Sjögren's syndrome is surprisingly common in pediatric patients who present with recurrent parotitis. Otolaryngologists who treat pediatric parotitis should have a high index of suspicion for Sjögren's syndrome. LEVEL OF EVIDENCE: 4.

Severe idiopathic pneumoparotitis: Case report and study review.

Parotitis is a frequent disease in general pediatrics. Pneumoparotitis is a rare affection that belongs to differential diagnoses of parotitis, along with infections, lymphadenitis, autoimmune disorders, inflammatory conditions, vascular malformations or neoplasms. It is usually described in musicians using wind instruments or in other situations involving a Vasalva maneuver. We report the case of a 12 years old boy with severe idiopathic pneumoparotitis without any of these well-known causes and whose autoimmune familial background of Sjögren syndrome might be relevant.

Role of Salivary Duct Morphology in the Etiology of Chronic Obstructive Parotitis: Statistical Analysis of Sialographic Features and Computational Fluid Dynamics Analysis of Salivary Flow.

PURPOSE: The causes of some cases of chronic obstructive parotitis (COP) without obstructive factors are still unclear. The authors hypothesized that some morphologic features of salivary ducts might contribute to the development of COP. This study investigated the role of salivary duct morphology in the etiology of COP. MATERIALS AND METHODS: The authors designed and implemented a case-and-control study. Cases were defined as patients with COP, diagnosed from September 2014 to May 2017 at the Affiliated Hospital of Stomatology of the Sun Yat-sen University (Guangzhou, China), and controls were healthy participants. The primary predictor variables were the occurrence of an accessory duct (AD), the number of branches uniting to form the Stensen duct (SD), the angle between the AD and the SD, and the angle between branches identified on sialographic computed tomograms. Data from the 2 groups were compared to investigate the association between these variables and COP. The χ2 test, Student t test, and logistic regression were computed, with significance set at a P value less than .05. Fluid dynamics analysis was used to analyze salivary flow field in models of salivary ducts with different morphologic features reconstructed from sialographic computed tomograms. RESULTS: The sample was composed of 39 patients with COP and 18 controls without COP. The 2 groups were not similar for incidences of an AD (71.8 vs 38.9%) and the angle between branches (96.5 ± 26.0° vs 71.5 ± 21.2°). There was no relevant difference between groups in the number of branches and the angle between the AD and the SD. The area of low velocity was larger in the model with the wider angle between branches. CONCLUSIONS: The results suggest that the presence of an AD and a wider angle between duct branches are associated with COP.

Buccal space malignancy in the setting of chronic sialadenitis: A report of 2 cases.

We report the cases of an 89-year-old woman and a 77-year-old woman with long-standing chronic sialadenitis (60 and 10 years, respectively) who were referred to our large academic medical center for sialendoscopy. Both patients presented with symptoms of acute parotid duct obstruction in the background of long-standing parotid duct disease. Imaging demonstrated ductal dilation and periductal inflammation and, along with the clinical findings, was supportive of a diagnosis of acute parotitis in the setting of chronic obstructive parotid disease. Both patients underwent sialendoscopy. Intraoperative findings suggested the presence of a mass lesion in both cases, and biopsy confirmed a buccal space malignancy in each. Although benign processes such as ductal strictures and sialolithiasis are frequent causes of parotid duct system complaints, the possibility of a malignancy should be entertained and ruled out. Even in patients who have long-standing obstructive parotid symptoms, malignancy can be encountered as a new diagnosis. We discuss the unique presentation, workup, and management of our 2 patients, and we briefly review the current literature.

Viral etiology of sporadic cases of parotitis among children in Korea during 2013-2014.

Recent years have seen a high incidence of mumps, which is generally diagnosed based on clinical features, especially parotitis, without laboratory confirmation in Korea. To better understand the epidemiology of mumps in Korean children, we investigated sporadic suspected mumps cases with parotitis. In total, 237 buccal swabs or throat swabs collected from children with parotitis who had been clinically diagnosed with mumps were tested using real-time PCR for the detection of six viruses (Epstein-Barr virus, Human herpesvirus 6, Mumps virus, Human parainfluenza virus-1, -2, -3, Human adenovirus, Human bocavirus). Among 237 parotitis cases, 87 (36.7%) were positive for at least one virus; a single infection was observed in 73 (83.9%) cases, and co-infections were detected in 14 (16.1%) cases. Epstein-Barr virus was most frequent (20.7%), followed by human herpesvirus 6 (8.0%), mumps virus (5.5%), human parainfluenza virus-3 (4.6%), human adenovirus (4.2%), and human bocavirus (0.4%). These data suggested that the sporadic suspected mumps in the children might be related to other respiratory viruses rather than to the mumps virus. Our findings also indicate the limitation of clinical diagnosis without laboratory confirmation for mumps and thus highlight the importance of laboratory testing in suspected mumps cases.

Facial and limb angioedema with parotitis and Kikuchi-like necrotizing lymphadenitis preceding neuropsychiatric systemic lupus erythematosus in a young African American male.

Angioedema has been observed in a few cases secondary to systemic lupus erythematosus (SLE). Herein, we report a rare case where a young healthy male initially presented with angioedema, lymphadenopathy and parotitis and later on developed neuropsychiatric manifestations at the very onset of his SLE disease. This case illustrates the importance of prompt clinical consideration of lupus with unusual and atypical preceding manifestations.

Sarcoidosis presenting with acute dacryoadenitis.

Sarcoidosis is a systemic inflammatory disorder, pathologically characterized by noncaseating epithelioid granulomas. We report a case of the disease that presented with acute dacryoadenitis followed by acute parotitis.

[Primary Sjögren syndrome in a child]. / Syndrome de Goujerot-Sjögren primitif de l'enfant : à propos d'un cas.

Sjögren syndrome is uncommon in children and occurs most often in association with autoimmune diseases (secondary Sjögren syndrome). We describe the clinical and biological features of a 7-year-old girl with primary Sjögren syndrome revealed by recurrent parotiditis. CASE REPORT: A 7-year-old girl was referred for investigation of multiple episodes of parotid swelling since age 4 years, without systemic symptoms. The examination was unremarkable except for enlarged and painless parotid glands. Laboratory investigations and labial salivary gland biopsy revealed Sjögren syndrome without associated disease. Hydroxychloroquine was prescribed with clinical improvement. CONCLUSION: Recurrent parotiditis in children is an uncommon condition. The onset of parotid swelling at 5 years or over deserves screening for disimmune disorders, sarcoidosis, or Sjögren syndrome. Diagnosis of Sjögren syndrome is based on diagnostic criteria.

Sialoendoscopy combined with an internal stent and postoperative massage as a comprehensive treatment of delayed I131-induced parotitis.

A common complication of radioiodine (I131) treatment of thyroid cancer is parotitis. Here we describe our clinical experience in treating delayed I131-induced parotitis using sialoendoscopy together with an internal stent and postoperative massage. In this retrospective cohort study we reviewed 32 patients who were treated in that way under general anaesthesia between July 2010 and March 2015. Their age, sex, and the time to development of the parotitis were collected from the hospital's database. All patients were evaluated using a visual analogue scale (VAS), sialography, and computed tomography preoperatively. The analyses of VAS scores were made during postoperative follow-up visits. We used the paired Student's t test and one-way ANOVA to assess the significance of differences, and probabilities of < 0.05 were accepted as significant. The mean (SD) age of the 32 patients was 50 (11) years, and they developed symptoms of delayed parotitis after a mean (SD) of 12 (11) months. The mean time between treatment with I131 and sialoendoscopy was 26 (10) months. Ductal stenosis was the most common sialoendoscopic feature, together with mucous plugs and fibrosis. Fifty of the 56 ducts were successfully dilated by sialoendoscopy, and VAS scores significantly decreased from a preoperative 7.3 (1.1) to a postoperative 3.3 (2.1) (p=0.000) during follow-up of 3 - 41 months. Sialoendoscopic interventions combined with an internal stent and postoperative massage may be optimal comprehensive treatment for delayed I131-induced parotitis.

Sialendoscopy-assisted treatment for chronic obstructive parotitis related to Sjogren syndrome.

OBJECTIVES: Chronic obstructive parotitis related to Sjogren syndrome is not uncommon, but it is rarely reported in the literature. The aim of this study was to describe our experience in the treatment of chronic obstructive parotitis related to Sjogren syndrome. STUDY DESIGN: Seventeen cases of chronic obstructive parotitis related to Sjogren syndrome treated with sialendoscopy from June 2014 to June 2015 at the Department of Oral and Maxillofacial Surgery, School of Stomatology, China Medical University, were retrospectively reviewed. The cohort underwent ultrasonography, salivary gland scintigraphy, and sialography before sialendoscopy. All patients were asked to complete a visual analogue scale (VAS) evaluation before and 6 months after surgery. A paired t test was conducted, and P < .05 was considered statistically significant. RESULTS: The 17 study patients (27 parotid glands) successfully underwent interventional sialendoscopy under local anesthesia. The mean preoperative VAS score was 6, and the mean VAS score 6 months after sialendoscopy was significantly lower at 4.5 (P < .05). CONCLUSIONS: Interventional sialendoscopy plays a significant role in the treatment of chronic obstructive parotitis related to Sjogren syndrome.

Parotiditis crónica recurrente infantil: una revisión actualizada de la literatura / Recurrent chronic parotiditis in childhood: an update of the literature

La parotiditis crónica recurrente infantil (PCRI) es una patología relevante. Su diagnóstico es principalmente clínico, pero se apoya en exámenes imagenológicos. El enfoque actual del tratamiento es diverso. El objetivo es realizar una revisión actualizada sobre las características clínicas, exámenes complementarios, modelos etiopatogénicos y protocolos terapéuticos. MATERIAL Y MÉTODO: Se realizó una búsqueda bibliográfica en PUBMED utilizando los términos libres y términos MESH: PCRI, parotiditis recurrente, parotiditis crónica y parotiditis. Los filtros utilizados fueron pacientes humanos, hasta 18 años, con resumen. En el buscador Scielo se incluyeron los términos libes Parotiditis y crónica. Se incluyeron artículos publicados en idiomas inglés, español o portugués hasta el año 2017. RESULTADOS: En el buscador PUBMED se encontraron 119 artículos de los cuales sólo se incluyeron 44. La exclusión de los artículos restantes se debió a idioma, acceso al artículo o ausencia de relación entre el artículo y la revisión propuesta. En el buscador Scielo se encontraron 6 artículos de los cuales 5 fueron seleccionados. La evaluación multidisciplinaria permite el tratamiento oportuno. Su diagnóstico es clínico pero se apoya en exámenes imagenológicos, como la ecografía y la sialografía. CONCLUSIONES: El enfoque actual de tratamiento es conservador, y la mejor evidencia disponible apoya el uso de sialendoscopia con irrigación y administración de antibióticos y/o corticoides vía conducto parotídeo, sin embargo, existirían buenos resultados con lavados intraglandulares con soluciones fisiológicas sin necesidad de sialendoscopio.

Recurrent childhood chronic parotiditis (RCCP) is a relevant pathology. Its diagnosis is mainly clinical, but it relies on imaging tests. The current treatment approach is diverse. The aim of this article is to update the clinical features, complementary tests, etiopathogenic models and therapeutic protocols of this disease. MATERIAL AND METHOD: A bibliographic search was performed in PUBMED using the free terms and MESH terms: RCCP, recurrent parotiditis, chronic parotiditis and parotiditis. The filters used were human patients, up to 18 years old, with abstract. In SCIELO the free terms included were Parotiditis and chronic. Articles published in English, Spanish or Portuguese until 2017 were included. RESULTS: In PUBMED 119 articles were found and 44 were included. The exclusion of the remaining articles was due to language, access to the article or absence of relationship between the article and the proposed revision. In SCIELO 6 articles were found 6 of which 5 were selected. The multidisciplinary asses of patients with RCCP is considered the appropriate treatment. Its diagnosis is clinical but it relies on imaging tests, such as echography and sialography. CONCLUSIONS: The current treatment approach is conservative, and the best available evidence supports the use of sialendoscopy with irrigation and administration of antibiotics and/or corticosteroids via the parotid duct. However, there would be proper results with intraglandular lavage with physiological solutions without the need for a sialendoscope.

Bilateral parotitis in a patient under continuous positive airway pressure treatment / Parotidite bilateral em paciente sob tratamento com pressão positiva contínua das vias aéreas

Abstract Background and objectives: Many conditions such as bacterial and viral infectious diseases, mechanical obstruction due to air and calculi and drugs can cause parotitis. We present a case of unusual bilateral parotitis in a patient under non-invasive continuous positive airway pressure (CPAP) therapy for chronic obstructive pulmonary disease exacerbation in intensive care unit. Case report: A 36-year-old patient was admitted to intensive care unit with the diagnosis of chronic obstructive pulmonary disease exacerbation. Antibiotherapy, bronchodilator therapy and non-invasive positive pressure ventilation were applied as treatment regimen. Painless swellings developed on the 3rd day of admission on the right and a day after this on the left parotid glands. Amylase levels were increased and ultrasonographic evaluation revealed bilateral parotitis. No intervention was made and the therapy was continued. The patient was discharged on the 6th day with clinical improvement and regression of parotid swellings without any complications. Conclusions: Parotitis may have occurred after retrograde air flow in the Stensen duct during CPAP application. After the exclusion of possible viral and bacteriological etiologies and possible drug reactions we can focus on this diagnosis.

Resumo Justificativa e objetivos: Muitas condições podem causar parotidite, incluindo doenças infecciosas virais e bacterianas, obstrução mecânica por causa da presença de ar, cálculos e medicamentos. Apresentamos um caso de parotidite bilateral incomum em um paciente sob tratamento com pressão positiva contínua não invasiva das vias aéreas (PPCVA) para exacerbação da doença pulmonar obstrutiva crônica em unidade de terapia intensiva. Relato de caso: Paciente de 36 anos, internado em unidade de terapia intensiva com diagnóstico de exacerbação da doença pulmonar obstrutiva crônica. Antibioterapia, terapia broncodilatadora e ventilação com pressão positiva não invasiva foram aplicadas como regime de tratamento. No terceiro dia de internação, inchaços indolores desenvolveram‐se à direita da glândula parótida e, depois, à esquerda. Os níveis de amilase aumentaram e o exame ultrassonográfico revelou parotidite bilateral. Nenhuma intervenção foi feita e o tratamento foi continuado. O paciente recebeu alta no sexto dia, com melhoria clínica e regressão do inchaço da parótida, sem complicações. Conclusões: A parotidite pode ter ocorrido após o fluxo retrógrado de ar do duto de Stensen durante a aplicação de PPCVA. Após a exclusão de possíveis etiologias virais e bacteriológicas e possíveis reações medicamentosas, podemos focar no diagnóstico.
