Abstract
BACKGROUND Juvenile idiopathic recurrent parotitis (JIRP) in children is a condition characterized with recurrent episodes of idiopathic parotid gland inflammation. Since there are no definitive guidelines for diagnosis and management of this condition, we present a consecutive case series of patients with more than one decade follow up and their dramatic response to short course treatment by prednisolone. METHODS We conducted this study by retrospectively reviewed medical charts of children who were diagnosed with JIRP, from 1 January 2002 to 29 February 2023. We performed usual serological tests to exclude some possible background. We administered short course prednisolone on first day of episode as divided dosage (0.5 mg /kg). RESULTS In this case series of 10 patients (70%) were male, median age of onset was 5 years, duration of episodes 5 days, and the mean course of disease were 3.8 years. The average follows up of patients was near 10 years. In comparison with their natural course of disease all patients showed a dramatic response to treatment on the first day of administration of prednisolone (P Value 0.005). For ten years follow up there was not any additional accompanying autoimmune disorder. CONCLUSION Short course prednisolone on first day of each episode and its dramatic and meaningful response in our patients, introduce a new, effective, fast, and inexpensive regimen of therapy in patients with JIRP.

[PMID: 34930210 PMCID: PMC8691005 DOI: 10.1186/s12887-021-03004-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Accepted: 11/13/2021] [Indexed: 11/10/2022] Open
Abstract
Background IgG4-related disease (IgG4-RD) includes a group of immune-mediated diseases histologically characterized by lymphoplasmacytic infiltrate with a prevalence of IgG4-positive plasma cells, storiform fibrosis and obliterative phlebitis. Autoimmune pancreatitis, sialadenitis, dacryoadenitis and retroperitoneal fibrosis are the most frequent manifestations. IgG4-related sialadenitis usually affects submandibular glands and is very rare in children. Here we report the case of IgG4-related sialadenitis in a six-year-old patient previously diagnosed as juvenile recurrent parotitis. Case presentation A six-year-old patient was referred to our Centre for left parotid swelling of 4 × 3 cm, that was tender, soft in consistency, with overlying red and warm skin. His general condition was good but he was subfebrile; general examination revealed mild enlargement of left cervical lymph nodes. In the last 2 years he had had five episodes of parotitis, diagnosed by another pediatric Center as juvenile recurrent parotitis. On ultrasound examination the left parotid gland appeared enlarged, inhomogeneous, with a colliquative intraparotid lymph node and no evidence of sialolithiasis. Laboratory tests showed an increase of white blood cells and anti-VCA IgM and IgG positivity, with anti-EBNA e anti-EA I negativity. The patient was initially treated with oral antibiotics, but after 10 days the parotid became fluctuating, requiring surgical biopsy and drainage. Postoperative course was regular, with complete remission under oral antibiotic and steroid therapy. Microbiological tests, including cultures for aerobic and anaerobic bacteria, mycobacteria and Bartonella, were negative. Surprisingly, histology showed marked fibrosis and histiocytic and lymphoplasmacellular infiltrate with polyclonal plasma cells mostly expressing IgG4 immunoglobulins. Thus, the diagnosis of IgG4 related chronic sialadenitis in recurrent parotitis and recent EBV infection was made. Conclusions IgG4-related sialadenitis is very unusual in children. Histology plays a key role in diagnosis, considering that up to 30% of patients have normal serum IgG4 levels, as shown in our case. The lack of previous histological data makes it impossible to attribute our patient’s previous episodes of parotitis to IgG4-RD, though it is a very consistent possibility.

Abstract
INTRODUCTION Juvenile 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 METHODS A 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. RESULTS Of 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). CONCLUSION Juvenile 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.

Abstract
Juvenile recurrent parotitis is a rare recurrent inflammation of the parotid glands occurring in children. The etiology remains obscure and the treatment is still debated. In the present study, we perform a systematic review of the literature with the purpose of identifying and discussing the treatment options emerged over the last 28 years in order to prevent recurrent episodes of parotitis. We ultimately included 24 studies. The definitions used for juvenile recurrent parotitis varied widely and none of the selected studies referred exactly to the same definition. Only one was a randomized controlled trial and it showed marked benefits with the use of Bear Bile and Huangqi, two traditional Chinese medicines. Two additional study on sialendoscopy included a control group but was not randomized. All the remaining contributions were case series or case reports. The vast majority (n = 19) of the selected studies reported on sialendoscopy. They all documented improvement of the condition following this intervention. An analysis grouping all these studies (corresponding to 336 children) showed that only 25.8% (95% Confidence Interval: 21.5-30.8) of the treated children had further recurrences. However, the only two controlled study on sialendoscopy showed a similar improvement in controls. The remaining four studies were on sialography (n = 2), on oral appliance in the specific group of children with concomitant dental malocclusion (n = 1) on ductal hydrocortisone infusion through catheter inserted in the parotid duct (n = 1). Improvements were documented in all four contributions. This systematic review of the literature did not consent us to draw definite conclusions on the most suitable treatment for juvenile recurrent parotitis. The available evidence is indeed weak and difficult to interpret because of the scarcity of randomized controlled trials, the heterogeneity of the definitions used and the high rate of spontaneous resolution. Future large and well-designed randomized controlled trials that will include children fulfilling a shared definition of the condition are warranted.

Abstract
Recent technological improvements in head and neck field have changed diagnostic and therapeutic strategies for salivary disorders. Diagnosis is now based on colour Doppler ultrasonography (US), magnetic resonance (MR) sialography and cone beam 3D computed tomography (CT), and extra- and intracorporeal lithotripsy, interventional sialendscopy and sialendoscopy-assisted surgery are used as minimally invasive, conservative procedures for functional preservation of the affected gland. We evaluated the results of our long-term experience in the management of paediatric obstructive salivary disorders. The study involved a consecutive series of 66 children (38 females) whose obstructive salivary symptoms caused by juvenile recurrent parotitis (JRP) (n = 32), stones (n = 20), ranula (n = 9) and ductal stenosis (n = 5). 45 patients underwent interventional sialendoscopy for JRP, stones and stenoses, 12 a cycle of extracorporeal shockwave lithotripsy (ESWL), three sialendoscopy-assisted transoral surgery, one drainage, six marsupialisation, and two suturing of a ranula. Three children underwent combined ESWL and interventional sialendoscopy, and seven a secondary procedure. An overall successful result was obtained in 90.9% of cases. None of the patients underwent traditional invasive sialadenectomy notwithstanding persistence of mild obstructive symptoms in six patients. No major complications were observed. Using a diagnostic work-up based on colour Doppler US, MR sialography and cone beam 3D TC, children with obstructive salivary disorders can be effectively treated in a modern minimally-invasive manner by extracorporeal and intracorporeal lithotripsy, interventional sialendoscopy and sialendoscopy-assisted transoral surgery; this approach guarantees a successful result in most patients, thus avoiding the need for invasive sialadenectomy while functionally preserving the gland.

Abstract
Recurrent parotitis is a non-obstructive, non-suppurative inflammatory disease which is characterized by unilateral or bilateral parotid gland swelling attacks. It is also known as juvenile recurrent parotitis. Although the etiology is unknown, congenital malformations of the ductus, genetic predisposition, infections, allergies, autoimmune diseases, and some immune deficiencies are blamed. Here, we present a case report of recurrent parotitis with selective immunoglobulin A deficiency in a six-year-old boy. The patient was presented to us with a new episode of swelling of left parotid region. In the last 2 years, the patient suffered from recurrent parotitis which lasted for approximately 5 days in ten individual episodes.

Abstract
AbstractAims:To evaluate modern diagnostic and therapeutic management of juvenile recurrent parotitis, and to show the benefits of operative sialoendoscopy on the basis of our experience in 14 patients and the results of others.Results:Ultrasonography is sensitive in detecting the pathological features of juvenile recurrent parotitis. Interventional sialoendoscopy is a safe and effective method of treating the disease. In our case series, after a mean follow-up time of 30 months only 5 patients experienced recurrence of symptoms, with a mean symptom-free period of 20 months.Conclusion:The use of modern, minimally invasive diagnostic tools such as colour Doppler ultrasonography, magnetic resonance sialography and sialoendoscopy represents a new frontier in the management of juvenile recurrent parotitis. Operative sialoendoscopy also has the important therapeutic benefit of reducing the number of recurrences of acute episodes of parotitis, thus giving patients a better quality of life until puberty.

Abstract
IgA deficiency is the most common human primary immune-deficiency. We evaluated the clinical and immunological characteristics of selective IgA deficiency in children in Israel. The study group included 63 children diagnosed with IgA deficiency from 1987 to 2005. Mean follow-up time per child was 10.6 years. Average age at diagnosis was 10.5 years. In one child, the IgA deficiency was transient. Infectious diseases, mainly recurrent pneumonia and ear infection, were common and occurred in 25 patients (39.7%). Allergic diseases were documented in 20 (31.7%) of our patients. Thirteen children (20.6%) had autoimmune diseases. Malignancies were diagnosed in three children (4.8%), an association that has not been reported in previous series. IgA deficiency appears to be a risk factor for infections, allergic diseases, autoimmune conditions, and malignancy.

Abstract
Oral conditions in selective IgA deficiency in children have rarely been published. Our aims were to investigate their mucosal, periodontal, and cariological conditions in IgA deficient children matched with healthy controls and to draw data on their oral health in the North-East Region of Hungary. Thirty four patients and 111 healthy controls, matched by age and sex, were studied for oral mucosal disorders, periodontal disease, and caries. Mucosal diseases were found in 10 (29%) patients. The severity of periodontal lesions characterized by plaque index, gingival index and pocket depth (exceeding more than 3 mms) was similar in patients and controls. A significant difference was observed in caries experience of the primary, but not in the permanent dentition as assessed by the dmf/DMF-t/T; s/S system used universally to quantitate decayed, missing, and filled teeth and tooth surfaces both in primary (small letters) and in permanent (capital letters) dentitions. Patients with IgA deficiency had significantly higher dmft, and dmfs indices than controls, supporting the notion that children with selective IgA deficiency exhibit an increased risk for developing dental caries. However the severities of mucosal or periodontal disorders are comparable with that in the normal population.

Abstract
Infantile chronic recurrent parotitis (ICRP) is an insidious disease whose etiopathogenesis remains an enigma. Alterations in the physical appearance of parotid saliva from ICRP patients have been frequently reported. However, sialochemical studies in regard to ICRP are very rare. The aim of this study was to determine whether saliva of ICRP patients presents major physicochemical and biochemical alterations compared with saliva from paired healthy controls. Parotid, whole, and submandibular/sublingual saliva was collected at an asymptomatic stage from 33 ICRP patients (5-16 y old, both sexes) and from 33 sex- and age-matched healthy controls. Saliva was analyzed for protein concentration, mode of protein diffusion on cellulose membranes, unidimensional sodium dodecylsulfate (SDS)-polyacrylamide gel electrophoresis protein profiles and zymographic profiles of metalloproteinase 2 (MMP-2) and metalloproteinase 9 (MMP-9). Parotid saliva of ICRP patients showed an increased protein concentration, altered mode of protein diffusion, a higher frequency of polypeptide bands of 43, 37, 33, 29, 26, 16, and 10 kD, higher asymmetry in the polypeptide profiles of both contralateral parotid saliva, and an increase in the frequency of MMP-2 and MMP-9. Parotid saliva of patients with ICRP is molecularly altered with respect to normal saliva. Some of the molecular differences could be related to the etiopathogenesis of the disease.

Abstract
The soluble branched yeast beta-1,3-D-glucan (SBG) belongs to a group of carbohydrate polymers known to exert potent immunomodulatory effects when administered to animals and humans. A new oral solution of SBG has been developed for local application to the oropharyngeal and oesophageal mucosa in order to strengthen the defence mechanisms against microbial and toxic influences. In the present study oral administration of SBG has been investigated primarily for assessment of safety and tolerability in an early phase human pharmacological study (phase I). Eighteen healthy volunteers were included among non-smoking individuals. The study was an open 1:1:1 dose-escalation safety study consisting of a screening visit, an administration period of 4 days and a follow-up period. Groups of six individuals received SBG 100 mg/day, 200 mg/day or 400 mg/day, respectively, for 4 consecutive days. The dose increase was allowed after a careful review of the safety data of the lower dose group. No drug-related adverse event, including abnormalities in vital signs, was observed. By inspection of the oral cavity only minor mucosal lesions not related to the study medication were seen in seven subjects. Repeated measurements of beta-glucan in serum revealed no systemic absorption of the agent following the oral doses of SBG. In saliva, the immunoglobulin A concentration increased significantly for the highest SBG dose employed. SBG was thus safe and well tolerated by healthy volunteers, when given orally once daily for 4 consecutive days at doses up to 400 mg.
