SialadentitisSialadentitis
What is Sialadentitis?– Simply inflammation of the salivary glands– Can be due to a number of factors including:
Mumps infectionCoxacki VirusParainfluenzaSystemic Disease
Sialadentitis: EtiologySialadentitis: Etiology May be infectious:
– May be caused by bacterial or viral infections May be non-infectious:
– May be caused by systemic disease such as Sjogren’s or Sarcoidosis or even by radiation therapy
May be Post-Surgical:– Called “Surgical Mumps”– Pt kept without fluids and given atropine causes xerostomia
predisposing to inflammation May be Pharmacological:
– Drugs causing xerostomia May be architectural:
– Block of the salivary gland due to a stone
ParotitisParotitis Definition:
– Inflammation of the Parotid Gland May be infectious or non-infectious Common Causes:
– Mumps– Sjogren’s Syndrome– Bacterial infection of parotid gland usually Staph.
aureus– Blocked salivary duct – Stone in salivary duct
Parotitis: SymptomsParotitis: Symptoms Pain/ Tenderness of the Parotid Glands Enlargement of the Parotid Glands Infectious parotitis
– Acute bacterial parotitis: The patient reports progressive painful swelling of the gland; chewing aggravates the pain.
– Acute viral parotitis (mumps): Pain and swelling of the gland last 5-9 days. Moderate malaise, anorexia, and fever occur. Bilateral involvement is present in most instances.
– HIV parotitis: Nonpainful swelling of the gland occurs; otherwise, patient is asymptomatic.
Parotitis in tuberculosis: Chronic nontender swelling of one parotid gland occurs, or a lump is noted within the gland. Symptoms of tuberculosis are found in some cases.
Sjogren’s Syndrome: Recurrent or chronic swelling of one or both parotid glands with no apparent cause is noted. It is frequently associated with autoimmune disease. Discomfort is modest in most cases and is related to dry mouth and eyes.
Recurrent parotitis of childhood: Repetitious episodes of unilateral or bilateral mumps-like episodes in a young child are indicative.
Sarcoidosis: Chronic nontender swelling of parotid gland occurs
Overall Treatment for Parotitis Overall Treatment for Parotitis Acute:
– Antibiotics– Rehydration stimulating salivary flow– Possible IND
Chronic:– Eliminate causative agent:
Get rid of salivary stone/ other blockage– Warm Compresses– Sialogogues– Possible surgical resection – Ligation of the duct in hopes of atrophy
MumpsMumps
Mumps: (Viral Parotitis)Mumps: (Viral Parotitis)
Acute sialadenitis caused by RNA virus – Paramyxovirus
Other viruses causing salivary gland infection:
– Cytomegalovirus– Coxsackieviruses– Echovirus
Mumps: Clinical FeaturesMumps: Clinical Features Transmitted via airborne droplet Mainly effects the parotid gland Mainly effects children between the ages of 5-18 Has a 2-3 week incubation period Clinically:
– Will see rapid swelling of the parotids bilaterally– Acute pain when salivating
Clinical Features- continuedClinical Features- continued
When looking at the patient:– The ear lobe is elevated due to glandular enlargement
There may be a purulent discharge from the parotid duct but it is clear and unremarkable
Blood Work:– As the acini become infected the salivary amylase leaks
into the interstitium and is absorbed in the blood stream raising the serum amylase levels
Mumps: HistopathologyMumps: Histopathology
There is infiltration with plasma cells and the lymphocytes
The ductal lumens contain desquamated cell debris and leukocytes
Mumps: TreatmentMumps: TreatmentThere no effective antiviral therapy
available for the treatment of mumps.Analgesics and antipyretics are given to
control pain and feverLiquid diet with vitamins Bed rest
Sjogren’s SyndromeSjogren’s Syndrome
Sjogren’s SyndromeSjogren’s Syndrome
It is a group of autoimmune conditions with a marked predilection for woman, it has an intense T lymphocyte – mediated autoimmune process in salivary and the lacrimal glands as on of its most prominent component
Sjogren’s syndrome exhibits T cells infiltration and replaces the glandular parenchyma
Sjogren’s SyndromeSjogren’s SyndromeSjogren’s Syndrome:
– objective evidence of keratoconjunctivitis sicca – characteristic pathologic features of the salivary
glands– 2 out of 3 of:
recurrent chronic idiopathic salivary gland swelling unexplained xerostomia connective tissue disease
Sjogren’s Syndrome: Who is effected?Sjogren’s Syndrome: Who is effected?
Sjogren’s Syndrome can be Primary or Secondary:– Primary the syndrome is second to nothing
Only effects the salivary glands and the lacrimal glands
– Secondary Sjogren’s secondary to something like Rheumatoid Arthritis, SLE or Scleroderma
0.5-1% of the population is effected Age ranges for Sjogren’s 20-40 years 9:1 women effected more

Sjogren’s Syndrome: PathophysiologySjogren’s Syndrome: Pathophysiology Insult may start with a bacterial or viral infection. The
peptides and antigens associated with the bacterial or viral infection along with autoantigens (self being recognized as foreign) are associated with HLA II complex that gets expressed on CD4+ T Cells. Once the HLA is expressed, there is release of cytokines and further T Cell activation
After the initial attack of the CD4+ T Cells, B cells enter the gland and make autoantibodies, including, in many cases Anti-SS-A (Ro) and Anti-SS-B (La) (only Sjogren’s Syndrome) and in some cases Rheumatoid Factor. Via autoimmunity, and antigens being expressed to CD4+ T cells, the acini of the gland are destroyed
Pathophysiology: ContinuedPathophysiology: Continued Multifactorial disease SS is sometimes called autoimmune epithelitis in which there
is apoptosis of epithelial cells leading to degradation products and leading to antinuclear autoantigens to the immune system
Molecules within the TNF family play a big role in the polyclonal activation of B Cells. This, in turn leads to autoantibodies
There is known inhibition of healthy glands and/or the muscarinic receptors (via antibodies) and also abnormal function of aquaporins leading to poor function of remaining healthy glandular structure
There is prolonged/permanent activation of autoreactive B cells favoring oncogenic activity and possible development of B Lymphoma
Parotitis/Sjogren’s: HistologyParotitis/Sjogren’s: Histology Acute Parotitis:
– See inflammatory infiltrate (neutrophils) around the ductal system and acini
– Destruction of epithelial tissues Chronic Parotitis:
– Inflammatory infiltrate in the parenchyma of the gland (Plasma Cells and Lymphocytes)
The basic features are massive lymphoid infiltration with atrophy of the acini, proliferation of the cells of the small ducts that leads to narrowing of the lumen, and finally, obliteration of the gland

“Evaluation of sialometry and minor salivary gland biopsy in classification of Sjögren's Syndrome patients”
Revista Brasileira de Otorrinolaringologia vol.71 no.3 São Paulo May/June 2005 Liquidato et alCohort Study
There is no gold standard for the diagnosis of Sjogren’s Syndrome
In the past, biopsy and salivary flow rates were used Minor Salivary Gland biopsy is the most accurate
diagnosis means but is not used as a criteria for the diagnosis of Sjogren’s, rather it is helps confirm the diagnosis when there is a blood test confirming presence of Anti-SSA or Anti-SS-B
Study wants to know if there is a less invasive way to have an accurate diagnosis of Sjogren’s Syndrome
Why Do the Study?
Purpose of the StudyPurpose of the Study The present study aimed at assessing the role of minor
salivary gland biopsy and sialometry, either isolated or associated, as methods used to classify Sjögren's Syndrome based on the criteria defined by the European Community Study Group on Diagnostic Criteria for Sjögren's Syndrome
Materials and Methods: SubjectsMaterials and Methods: Subjects – 72 patients coming to the Department of Otorhinolaryngology, in
Sao Paulo Brazil from 1997 to 2003– Based on a criterion showed, they were submitted into the
investigation for diagnosis– Patients split into 2 groups those with the diagnosis of
Sjogren’s already, and those without the diagnosis of Sjogren’s– 26 pts with Sjogren’s and 46 pts not yet dx with Sjogren’s– Those with Sjogren’s were broken up into Primary or Secondary
Sjogren’s– To classify patients with primary Sjögren's Syndrome we
required the presence of 4 out of 6 items and item 4 (histopathology) or 6 (auto-antibodies) had necessarily to be present. As to classification of patients with secondary Sjögren's Syndrome, it required the presence of item 1 or item 2 plus 2 other items numbered 3, 4 and 5
Materials and Methods: Materials and Methods: Methods:Methods:
Non-stimulated sialometry:– Used 2 pre-weighed cotton balls– Subjects swallowed all saliva, then cotton balls put on the floor of
the mouth for 2 minutes, then weighed again– Anything 0.1ml/minute considered abnormal
Minor Salivary Gland Biopsy:– Horizontal incision parallel to the vermillion border of the lower
lip– Took about 4-6 minor salivary glands– Histopathological findings were graded as follows: normal gland;
mild inflammatory process; moderate inflammatory process; severe inflammatory process, and presence of inflammatory foci
A Review…A Review… sensitivity = probability of a positive test among patients with disease specificity = probability of a negative test among patients without
disease positive predictive value = the proportion of patients with positive
test results who are correctly diagnosed. It is considered the physician's gold standard, as it reflects the probability that a positive test reflects the underlying condition being tested for
negative predictive value = the proportion of patients with negative test results who are correctly diagnosed
Results:Results: As to the number of inflammatory foci found on biopsy:
– Those with Primary Sjogren’s had more than those with Secondary Sjogren’s who had more than those with no diagnosis of Sjogren’s
Current Article:– Biopsy Sensitivity of 72%, Specificity of 84%
Positive Predictive Value of 75% Negative Predictive Value of 82% Meaning 84% of the time, those with SS will have a positive biopsy Meaning 72% of the time, those without SS will have a negative biopsy Meaning 75% of the time, those with a positive biopsy will have SS dx
correctly Meaning 82% of the time, those with a negative biopsy will not have SS
– Sialometry Sensitivity of 62%, Specificity of 52% Negative Predictive Value of 71%
– Biopsy Accuracy 79%– Both Biopsy + and Sialometry + Specificity of 95%, PPV of 86%
ConclusionConclusion Sialometry higher sensitivity and specificity in Primary vs
Secondary group– There is higher likelihood of the subject not having Sjögren's
Syndrome when sialometry is negative Biopsy higher sensitivity and specificity in Primary vs Secondary
group– A subject would have 75% likelihood of having Sjögren's
syndrome when biopsy was positive and 81.6% likelihood of not having Sjögren's syndrome when biopsy was negative

Recurrent Parotitis as a First Manifestation of Adult Primary Sjogren’s Syndrome
Sugimoto et alThe Japenese Society of Internal Medicine
January 17th, 2006Case Report
Case SubjectCase Subject 38 year-old Japanese women with 3 year history
of bilateral parotitis Denied dry eyes, dry mouth, trouble swallowing,
arthralgias Lab Tests:
– Rheumatoid Factor– Positive for Anti-SS-A/Ro Antibodies (found in 45% of
Primary Sjogren’s Patients)– No Anti-SS-B/La Antibodies (found in 15% of Primary
Sjogren’s Patients)
Salivary Function:– Unstimulated Salivary Flow 0.2ml/10 min– Stimulated Salivary Flow 2.0ml/10 min
Labial biopsy of minor salivary glands revealed lymphocyte infiltration and glandular and ductal atrophy
Diagnosed with Primary Sjogren’s Syndrome
Salivary Function and Biopsy
ConclusionConclusion Recurrent Suppurative Parotitis is a common first manifestation in
children and adolescents Recurrent Parotitis being the first manifestation is rare, but can
happen Treatment for Recurrent Parotitis:
– Because of stasis of saliva within the gland, there is usually bacterial infection, thus antibiotics are common some literature promotes Antibiotic Prophylaxis to prevent this as some patients can feel prodromal symptoms before inflammation/infection of the gland
Point of the article:– Consider Sjogren’s Syndrome within the differential as the
underlying cause of Recurrent Parotitis, even in adults
Case Patient:Case Patient: Has had recurrent submandibular infection, stones, swelling to which the
glands were removed Has had his right lacrimal gland removed because of swelling Has now had recurrent bouts of Parotitis, some suppurative Has constant xerostomia for which Oasis mouth spray is used HAS NEVER BEEN WORKED UP FOR SJOGREN’S
– PCP NEVER MENTIONED IT– ENT DIDN’T MENTION IT– PLASTIC SURGEON BROUGHT IT UP
