Parotite ricorrente giovanile: inquadramento clinico e approccio diagnostico-terapeutico

Juvenile recurrent parotitis is an uncommon condition characterised by recurrent episodes of parotid swelling that affects school-aged and pre-school children and shows a typical tendency to self-resolution during adolescence. To date, etiopathogenetic hypotheses and treatment options are still debated, as there are no current guidelines for its diagnosis and treatment so far. This article aims to provide valid recommendations for the management of children with recurrent episodes of parotitis and tips to identify cases worthy of further investigation and referral to the specialist.

Outcomes from a Multidisciplinary Otolaryngology and Rheumatology Clinic for the Management of Chronic Sialadenitis.

Determine the outcomes in children with recurrent sialadenitis after establishment of a multidisciplinary pediatric otolaryngology and rheumatology clinic. Retrospective review. Single-center tertiary medical center. We reviewed all children presenting to a multidisciplinary pediatric otolaryngology/rheumatology clinic with recurrent parotitis between December 2019 and April 2023. Thirty-three children presented with recurrent parotitis to a multidisciplinary clinic. Seventy-seven percent of those with childhood Sjögren's disease (cSjD) had xerophthalmia, and 67% had xerostomia. The cSjD group was more likely to have both abnormal parotid and submandibular findings when compared to the non-cSjD group (P < .001). Sixteen percent of the cSjD group had a positive SSA/SSB autoantibody and 47% were antinuclear antibody positive. Fifty percent of the cSjD cohort had a focus score of ≥1 from a minor salivary gland biopsy. There were no significant differences from sialendoscopy outcome between the 2 groups. Seventy percent with juvenile recurrent parotitis showed partial response (PR) or complete response (CR) to sialendoscopy. In the cSjD cohort 3 (27%) reported a CR and 5 (45%) reported a PR. In the non csSjD cohort 5 (42%) reported a CR and 3 (25%) reported a PR. Ten of the 12 cSjD patients on hydroxychloroquine have shown symptom improvement. The establishment of a multidisciplinary otolaryngology and rheumatology clinic can provide a more comprehensive evaluation and treatment of the child with recurrent or persistent parotitis than from a regular ENT clinic.

Utility of sialendoscopy in the management of juvenile recurrent parotitis. Retrospective study

IntroductionJuvenile recurrent parotitis is a rare disease characterized by repeated episodes of inflammation affecting, unilaterally or bilaterally, the parotid glands during childhood. Material and methodsRetrospective study including patients diagnosed with juvenile recurrent parotitis between January 2010 and September 2020 at a tertiary level hospital, with the aim of evaluating the results of medical treatment and sialendoscopy. ResultsA total of 48 patients met the inclusion criteria and had a mean follow-up of 4 years (SD = 3; Min: 2/Max: 12). Regarding treatment, 34 (70.8%) patients received conservative treatment and had a mean of 5 episodes (SD = 3; Min: 2/Max: 13) until symptom resolution. Meanwhile, 14 (29.2%) patients underwent sialendoscopy, of which two (12%) required reintervention. In 100% (14) of the patients treated with sialendoscopy, the findings were consistent with JRP and, after sialendoscopy, a statistically significant reduction in episodes was observed, with a mean of 1 post-intervention episode (SD = 1.5; Min:0/Max: 6) (P < .001). ConclusionsThe results obtained in this study suggest that sialendoscopy is a useful tool in the treatment of juvenile recurrent parotitis. However, new studies comparing the results of sialendoscopy with other therapeutic alternatives are necessary.

Juvenile Recurrent Parotitis: Video-Documented Sialendoscopy

Juvenile recurrent parotitis (JRP) is characterised by recurrent episodes of painful parotid swelling in children. JRP is the second most common cause of parotitis in childhood, behind only paramyxovirus. The prevention of recurrent attacks represents the most dramatic and serious aspect of this pathology. Since 2004, different authors have evaluated sialendoscopy for the diagnostic and therapeutic management of JRP. In this paper, we share our clinical experience of the use of sialendoscopy for the treatment of JRP. We document with video sialendoscopy the glandular pathology in four children with a mean age of 11.5 years, who had suffered from 3–6 episodes/year of inflammation prior to treatment. The use of sialendoscopy in our patients was effective in preventing recurrences. For the first time, the videosialendoscopy of a series of children diagnosed with JRP is documented in the literature.

Key Findings and Experience in the Management of Juvenile Recurrent Parotitis with Sialoendoscopies—A Retrospective Study

Introduction: Juvenile recurrent parotitis (JRP) is characterized by intermittent swelling of one or both parotid glands, accompanied by pain and associated with non-obstructive sialectasia. Sialoendoscopy is considered a significant treatment for JRP, being a safe and minimally invasive treatment method with good clinical outcomes. The purpose of this study was to assess the procedure of sialoendoscopy as a treatment modality for JRP and discuss the relevant literature on this topic. Methods: This study retrospectively reviewed clinical records of children diagnosed with JRP who were treated in the Maxillofacial Department of the Tzafon Medical Center, Poriya, Israel, with sialoendoscopy between May 2016 and March 2023. Data on demographics, the site of symptoms, follow-up duration, treatment outcome, and complications were collected for each patient. The inclusion criteria were patients not older than 16 years of age, with at least two episodes of swelling of the parotid gland unilaterally or bilaterally during a time period of 6 months. The exclusion criteria were patients older than 16 years of age, and patients who were diagnosed with sialolithiasis or Sjogren’s syndrome. Results: The study included 17 children, of whom 12 (70%) were boys and 5 (30%) were girls. The mean age of the children at the time of the procedure was 6.7 years and ranged from 3 to 16. The affected parotid gland was the left in 7 children (41%), right in 9 children (53%), and bilateral in 1 child (6%). The average follow-up time was 45.17 months and ranged from 5 to 81 months. A total of 15 children (88%) were deemed to have a successful treatment result regarding the frequency of episodes after therapy and subjective improvement. Full resolution was seen in 10 children (59%). The sialoendoscopy findings were avascularity in the walls of the parotid duct, strictures, and mucous plugs. Pathological findings in sialoendoscopy were found in 11 out of 12 asymptomatic contralateral glands (p-value &gt; 0.001). Conclusions: Sialoendoscopy under general anesthesia is a worthwhile and practicable treatment method for treating JRP. Satisfactory results were seen in the vast majority of patients. It is recommended to perform bilateral sialoendoscopy also in cases of a unilateral symptomatic gland. This treatment method is effective, safe, and potentially repeatable.

Current Ultrasonography Potential in the Diagnosis of Juvenile Recurrent Parotitis

Objective: To determine the diagnostic significance of sonographic signs indicating the parotid glands’ condition in children with juvenile recurrent parotitis (JRP). Materials and methods: We examined 42 patients with JRP and 30 children aged 3-17 years from the control group. Both groups underwent B-mode and color Doppler ultrasonography of parotid glands to assess linear dimensions, contours, structures, echogenicity, pronouncement of the stromal component, parenchymal vascularization, and condition of intraglandular lymph nodes. The diagnostic significance of the sonographic signs was assessed by ROC analysis. Results and discussion: We found significant differences between the study and control groups in terms of such sonographic signs as gland enlargement, decreased parenchymal echogenicity, change in the echotexture, increased stromal component, increased parenchymal vascularization, and reactive parotid lymph nodes (P &lt; .05). With the high-frequency probe we were able to study the structure of JRP-associated hypoechoic foci in the parenchyma and prove that they are not cystic dilatation of the ducts but foci of infiltration around the peripheral ducts with structurally altered walls. Conclusions: Ultrasonography plays a pivotal role in the JRP diagnosis and can identify its most significant sonographic signs, such as increased size, distinctive changes in the parenchymal echotexture, decreased echogenicity, and increased parenchymal vascularization.

Sialendoscopy for pediatric salivary gland disorders: a study of safety and effect.

Sialendoscopy has become the preferred modality for managing pediatric salivary gland disorders (PSGD) including juvenile recurrent parotitis (JRP) and sialolithiasis. The literature remains sparse, but several case series have reported good outcomes and few complications. The aim of this study was to investigate the safety and efficacy of sialendoscopy for PSGD in a Danish setting. From a national sialendoscopy database, we included records of children who had undergone sialendoscopy for PSGD at our clinic over a 6-year period. Clinical and intraoperative data, follow-up and e-mail surveys after 1, 3 and 5 years were retrieved for analysis. We included 52 procedures on 50 glands (32 parotid, 18 submandibular) in 49 children. Of eligible patients, 90% attended clinical follow-up, 80% answered the survey after 1 year, 80% after 3 years and 60% after 5 years. JRP was diagnosed in 33 cases, obstructive causes in 18 cases. Complications noted were ductal perforation (2%), transient lingual nerve affection (4%) and infection (2%). For JRP patients, overall symptoms had improved for 96% after 3 months, 81% after 1 year and 83% after 3 years. For patients suffering from obstruction, overall symptoms were improved for 93% after 3 months and for 100% after 1 year. Sialendoscopy is a safe procedure for PSGD, and effective for sialolithiasis and symptom reduction in JRP.

Sialendoscopy in Management of Juvenile Recurrent Parotitis-A Single Centre Experience.

Juvenile recurrent parotitis is a rare inflammatory disease of the parotid gland that shares diverse therapeutic management between institutions. Sialendoscopy has been demonstrated as an efficient diagnostics and therapeutic method with minimal complications; however, due to the rarity of the disease and limited data, there is a lack of universal guidelines on its optimal management. Herein, we retrospectively analysed patients with juvenile recurrent parotitis who had the sialendoscopy performed at our tertiary centre. Descriptive data were retrieved along with the number of swelling episodes one year before and after the sialendoscopy intervention. In the last decade, twenty-nine sialendoscopic procedures were performed at our clinics on twenty-one patients diagnosed with juvenile recurrent parotitis. Most of them underwent the procedure under general anaesthesia (86%). In the year before and after the sialendoscopic procedure, the patients had 3.9 ± 2.7 and 0.2 ± 0.4 episodes of swelling per year, respectively. The difference proved to be statistically significant (p < 0.0001). The complete resolution was noted in sixteen patients (76%); however, the procedure was not repeated on the same side of any patient. Solely one patient had a relapse of the disease reported more than twelve months after the sialendoscopy, nonetheless, one of his exacerbation episodes was already reported in the first year after the sialendoscopy. The mean follow-up period of patients was 48.6 months (range, 13−116 months). All things considered, this study emphasises sialendoscopy as an effective minimally invasive diagnostic and therapeutic tool for the management of juvenile recurrent parotitis.

Superficial Parotidectomy for Juvenile Recurrent Parotitis.

To investigate long-term outcomes, imaging, and pathologic findings in pediatric patients who underwent superficial parotidectomy for recalcitrant juvenile recurrent parotitis (JRP). Records for 20 children (23 parotidectomies; 9 females, 11 males; age at surgery of 8.6 ± 3.7 years) collected over a 10-year period (2012-2021) were reviewed. Parents were contacted via telephone to obtain extended follow-up. A simplified scoring system was used to assess imaging findings and an additional pathologic review was conducted to further clarify the underlying disease process. All but one patient experienced resolution of their recurrent symptoms after superficial parotidectomy. Three of the patients studied required surgery on the contralateral side, and this could be predicted based on their imaging at the time of the initial surgery. Pathologic findings included ductal fibrosis, metaplasia, and dilatation as well as parenchymal atrophy and fatty deposition. There were no major surgical complications, however, the incidence of Frey's syndrome in this sample was 43.5% of surgical sites. For patients with frequent recalcitrant symptoms or significant quality of life impairment related to JRP, superficial parotidectomy represents a potential treatment option with the noted reduction in symptom burden following surgery. Further longitudinal studies are needed. 4 Laryngoscope, 133:1495-1500, 2023.

A Retrospective Analysis of Multiple Affected Salivary Gland Diseases: Diagnostic and Therapeutic Benefits of Interventional Sialendoscopy.

Multiple affected salivary gland diseases are rare compared to single gland diseases and represent a major diagnostic challenge. These cases are commonly neglected in the scientific literature, despite the considerable suffering of these patients. The aim of this retrospective study was to report disease characteristics, diagnostic pathways, and therapeutic options, including sialendoscopic treatment of multiple affected salivary gland disorders. Patients experiencing multiple affected salivary gland diseases treated between 2013 and 2020 were consecutively identified. Data regarding demographics, clinical presentation, disease characteristics, treatment, complications, and follow-up were analyzed retrospectively. In total, 71 patients were identified with these diseases and included obstructive disease without sialolithiasis (n = 22), inflammation (n = 15), immune disease (n = 19), radioiodine-induced sialadenitis (RAI) (n = 5), sialadenosis (n = 2), and juvenile recurrent parotitis (JRP) (n = 8). Diagnostic and therapeutic sialendoscopy was performed on 113 salivary glands in 42 patients, leading to completely (n = 27, 64.3%) or partially (n = 11, 26.2%) improved symptoms in most cases. In total, 4 patients did not improve after interventional therapy. Multiple affected salivary gland diseases are rare and diagnostically challenging. Interventional sialendoscopy offers an effective and safe therapeutic option and should be considered in this specific cohort.

Parotid irrigation: A promising option for juvenile recurrent parotitis

ObjectiveTo study whether irrigating the parotid gland with saline solution through the parotid duct reduces the number of inflammatory episodes in patients with juvenile recurrent parotitis (JRP) over a 1-year period. MethodsThis was a retrospective cohort study using the electronic clinical history data of patients with JRP that were treated with parotid irrigation under general anaesthesia at the Paediatric Surgery units of Consorci Sanitari Alt Penedès-Garraf and Hospital Universitari Mútua de Terrassa. The number of inflammation episodes in the year before and the year after treatment was analysed. ResultsA total of 15 patients with JRP were evaluated, of whom 10 met the criteria for irrigation. Data from 9 patients were available. The procedure was performed without incident in all of the patients. There was no difficulty with probing the duct and no need for orifice dilation. No post-lavage complications were observed.Four patients had complete resolution of inflammation events (44.4%), and the remaining 5 patients had a decrease in the number of events. The Wilcoxon signed-rank test showed a statistically significant difference between the number of inflammation events before and after the intervention (p = 0.009). ConclusionsParotid irrigation with saline solution could be a safe and effective first-line technique for the treatment of JRP. Level-of-evidenceIV.

Salivary Gland Disorders in Pediatric Patients: A 20 Years’ Experience

Salivary gland disorders are uncommon in children; they show a lower prevalence when compared to adults. The literature has a relative lack of information about the management and the different treatment protocols regarding these diseases. The aim of this research is to investigate the prevalence of both benign and malignant salivary gland disorders, focusing on diagnostic and therapy. An audit of patients diagnosed with salivary gland disorders was conducted from 2000 to 2020. 99 patients’ records were selected and analyzed: 51 males’ and 48 females’, age 10 ± 4 SD. Obstructive pathologies were the most frequently diagnosed (49 patients) followed by oncologic (21 patients), inflammatory (20 patients), rheumatologic (4 patients), malformative (3 patients) and infective disorders (2 patients). The parotid was the most affected major gland in 47 cases with a prevalence of diagnosis of juvenile recurrent parotitis (JRP) (40.4%), followed by the sublingual gland in 14 cases of ranula (100%) and the submandibular gland in 11 patients suffering from sialolithiasis (84.6%). Swelling was the most common symptom (75.7% of patients). Seven different neoplasms were documented. A greater prevalence of low-grade mucoepidermoid carcinoma among the malignant group (38.1% of oncologic cases) was noted. In regards to benign tumors, pleomorphic adenoma was the most common diagnosis (47.6% of cases). The symptoms and outcomes showed statistical significance concerning gender. Although salivary gland diseases in children and adolescents are rare, it is essential to observe and monitor all of the symptoms to intervene if necessary, as painless swelling is a symptom common from both benign and malignant diseases.

Ultrasound Findings in Juvenile Recurrent Parotitis - Case Series of Typical Presentation and Sonographic Observations

Juvenile recurrent parotitis is a recurrent inflammatory parotitis seen in children. It is a benign condition of rare occurrence. This condition is usually mistaken for other conditions leading to multiple investigations. Three cases of children presenting with recurrent attacks of parotitis have been being described in this case series. They showed mild leukocytosis and elevated CRP during the episodes of parotitis. Similar observations in all the children have been made on high resolution ultrasound. Multiple small hypoechoic nodules in glandular parenchymal echo were observed. The observed nodulations were possibly due to lymphoid hyperplasia. Observation of these features can help in diagnosing this condition. Ultrasound can also be used to rule out sialoliths and to rule out other possible causes of sialadenitis.

Common Characteristics and Clinical Management Recommendations for Juvenile Recurrent Parotitis: A 10-Year Tertiary Center Experience.

ObjectiveJuvenile recurrent parotitis (JRP) is a rare disease that may adversely affect normal development and quality of life. The objective of this study was to report on the demographics, characteristics, and treatment outcomes of JRP and to offer evidence-based management recommendations.Study DesignRetrospective review.SettingA single tertiary care pediatric teaching hospital.MethodsMedical records, imaging studies, and laboratory findings over a 10-year period were retrospectively collected and reviewed, resulting in 41 patients with JRP between the ages of 8 months and 16 years.ResultsBlack males aged 2 to 8 years were most commonly affected by JRP. Overall, 18 (44%) patients received ≥3 antibiotics, and 17 (42%) underwent sialendoscopy for treatment. Over 75% of patients had no JRP recurrences after 3 sialendoscopies. The most common imaging approach was computed tomography (42%), and the most frequent laboratory results were elevated amylase (83%) and C-reactive protein (82%). Atopy (61%) and excess weight (42%) were routinely associated with JRP, especially in severe cases.ConclusionJRP workup and treatment plans should begin with the least burdening modalities, including over-the-counter analgesics, minimal laboratory studies in the acute phase, and ultrasonography over computed tomography. Clindamycin is an effective initial antibiotic of choice, and severe recurrences may be controlled with sialendoscopy. Optimizing the health of patients with JRP includes managing comorbidities, especially of atopic and overweight origins, which are associated with more severe cases.

Cost analysis of sialendoscopy for the treatment of salivary gland disorders in children

IntroductionRecent advances in Otolaryngology have changed the diagnosis and therapy for salivary gland disorders. Sialendoscopy-assisted surgery is a minimally invasive, conservative procedure for functional preservation of the affected gland. The goals of this study are to assess the indications, use, and outcomes of pediatric sialendoscopy at a tertiary pediatric institution as well as to analyze the direct cost related to the diagnosis and treatment of patients with sialolithiasis and Juvenile Recurrent Parotitis managed with sialendoscopy. MethodsRetrospective cohort study of pediatric patients undergoing diagnostic and/or therapeutic sialendoscopy at a tertiary level children's hospital between 2012 and 2020. Demographic, clinical, surgical variables and direct hospital costs 1 year before and after the sialendoscopy procedure were collected and analyzed. ResultsTwenty-two pediatric patients were included. There was male predominance (59.3%). The most common indication for sialendoscopy was Juvenile Recurrent Parotitis. Average age of onset was 6.5 years for patients with JPR and 14.2 years for patients with sialolithiasis. All patients had an average of 4.5 episodes before the first procedure. 8 patients required repeat sialendoscopy for recurrent symptoms. Mean total hospital costs were significantly higher in patients with JRP 1 year before and after the sialendoscopy ($4308.8 vs. $3330) compared to patients with sialolithiasis. Costs of the sialendoscopy and related expenses including anesthesia and PACU cost were similar in both studied groups ($13,506 vs. $13,022.9). Complete resolution of symptoms was achieved in 14 patients with JRP and all patients with sialolithiasis. ConclusionSialendoscopy is a low-risk procedure that aids in the treatment for pediatric salivary gland disorders. The costs related to sialendoscopy are substantial and patients with JRP incur higher hospital preoperative and postoperative costs compared to patients with sialolithiasis.

The applicability of ultrasound in the diagnosis of inflammatory and obstructive diseases of the major salivary glands: a scoping review.

The purpose of the present scoping review was to determine the contribution of ultrasound images in the diagnosis of inflammatory and obstructive diseases of the major salivary glands (MSGs). A search of studies of ultrasonographic assessments of human samples was performed in several electronic databases and grey literature up to July 2021. The extracted data were the examined MSG; the diagnostic value of ultrasound (sensibility, specificity, positive- and negative predictive value, accuracy); features of lesions, including number, echogenicity, echotexture, form, margins, size, posterior acoustic aspect, and location; and related clinical information, such as swelling, palpation, sensible to pain, salivation, lymph nodes, recurrence, duration, and causes. After verifying the eligibility criteria, 90 articles focused on detecting inflammatory, and obstructive diseases of the MSG were gathered, with variable study designs and size samples. A wide variety of pathologies were assessed, including sialolitiasis (n = 45), acute sialadenitis (n = 30), chronic sialadenitis (n = 25), granulamatous diseases (n = 15), Kuttner's tumor (n = 11), juvenile recurrent parotitis (n = 9), abscess (n = 7), post-radiotherapy sialadenitis (n = 6), sialadenosis (n = 9), abscess (n = 7), IgG4-related disease sialadenitis (n = 5), HIV-sialadenitis (n = 4), obstructive sialadenitis (n = 3), iodinated contrast-induced sialadenitis (n = 2), and pneumoparotitis (n = 1). Most studies were case reports or series of cases. Few studies exhibited data about the accuracy of ultrasound in detecting MSG diseases. The present scoping review concluded that ultrasound aspects of different MSG pathologies are similar but contribute to their differential diagnosis and can be considered as a valuable initial method for assessing the MSG of adults and children.

Immune disorders associated with juvenile recurrent chronic parotitis

IntroductionJuvenile recurrent chronic parotitis (JRCP) is a rare disease of unknown cause. There is a growing interest in its autoimmune aetiology and its relationship with dysfunctions of cellular and humoral immunity, although there is no agreed protocol for complementary investigations for its study. A consecutive series of cases is presented where the immune alterations and associated autoimmune disorders are investigated, proposing a study algorithm. Patients and methodsA retrospective study was carried out on patients who had JRCP during the period from 2013 to 2016 and a follow-up of at least 2 years. After its clinical and ultrasound diagnosis, complementary examinations were systematically carried out to investigate infectious, immune, and autoimmune diseases. ResultsOf a total of 36 patients with inclusion criteria, 16 (44%) were found with some analytical alteration of a non-specific immunological nature (positive ANA, high IgG, low complement factor 4), or associated with a specific diagnosis, as occurred in 11 patients: Selective IgA deficiency (2), Sjögren’s syndrome associated or not with systemic lupus erythematosus (3), coeliac disease associated or not with diabetes mellitus (4), Hashimoto’s thyroiditis (1), and acquired immunodeficiency syndrome (1). ConclusionJuvenile recurrent chronic parotitis can be considered a sentinel sign of other diseases of immunological/autoimmune aetiology for which the diagnosis, monitoring and early treatment can improve its prognosis. Viral infectious aetiology, with the exception of HIV, is not a priority in the study of recurrences.

Treatment of juvenile recurrent parotitis with irrigation therapy without anesthesia

PurposeNo standardized treatment regimen exists for juvenile recurrent parotitis (JRP). The investigators hypothesized that irrigation with saline only without local anesthesia will be an effective and beneficial option.MethodsUsing a retrospective study design, a series of children with typical symptoms of JRP who were treated with at least one irrigation therapy were evaluated. This treatment consisted of irrigation of the affected gland with 3–10 ml saline solution without any type of anesthesia. The outcome variables were patient/parent satisfaction, frequency and duration of acute JRP episodes, and the need for antibiotics before and after irrigation therapy.ResultsThe case series was composed of six boys aged 3.3–7.7 years who experienced one to eight sessions of irrigation therapy. The period of follow-up was 9–64 months. We observed a total resolution of symptoms in two children and an improvement in the other four. No relevant side effects were seen.ConclusionOur results suggest that irrigation therapy is a reasonable, simple, and minimally invasive treatment alternative for JRP. In contrast to sialendoscopy or sialography, there is no need for general anesthesia or radiation exposure.
