Neonatal suppurative parotitis: a study of five cases

Neonatal Suppurative Parotitis: Case Report and Review of Literature

Neonatal suppurative parotitis is a rare condition that is diagnosed primarily through clinical evaluation. The prognosis is generally good. In this report, we present the case of a 21-day-old female infant who was treated in our ENT department for neonatal suppurative parotitis. The patient presented with a feverish, hard, red, and tender swelling of the parotid loge which displaced the right earlobe outward. In addition, purulent exudate was observed from Stensen's duct. A computed tomography scan of the cervical and cerebral regions revealed a swollen right parotid gland with heterogeneous density and enhancement, but no detectable collection. The patient received intravenous antibiotics for 48 hours, resulting in a favorable outcome without the need for surgical treatment. The aim of this study is to emphasize the diagnostic and therapeutic aspects of this clinical condition. Suppurative parotitis should be suspected by the clinician in newborns who present with an inflammatory preauricular swelling, with or without contributing factors. The outcome is generally favorable, and complications are rare with timely and appropriate medical treatment.

Polymicrobial Acute Suppurative Parotitis in a 33-Day-Old Infant: A Case Report and Review of the Literature

BACKGROUND

Acute suppurative parotitis (ASP) of neonates is a rare condition characterized by irritability, erythema, and tenderness of the affected gland.

METHODS/RESULTS

Only few cases have been reported in Engilsh literature, mostly in male neonates, in a unilateral fashion. In our case, a polymicrobial etiology (Klebsiella pneumoniae, Staphylococcus aureus, Acinetobacter ursingii, and Acinetobacter junii) was found. Based on the review of the microbiological findings of cases of ASP in English literature for the years 1970 to 2020, S. aureus is the most commonly isolated microorganism (47% of the total 65 patients). Our patient was born with a C-section procedure and was not breast-fed, making dysbiosis along with the usage of the feeding bottle, possible risk factors for the development of ASP.

CONCLUSIONS

ASP may be due to polymicrobial etiology. Initial presentation in neonates may not include typical signs and symptoms, like fever. Aseptic technique of oral procedures is of utmost importance also in immune-competent neonates.

Late onset group B streptococcus disease manifesting as acute suppurative parotitis

•

Acute suppurative parotitis (ASP) caused by GBS primarily arises from bacteremia.

•

Infectious route of is different between ASP infants by GBS and non-GBS pathogens.

•

ASP should be included in an infectious focus as late-onset GBS disease.

•

Blood cultures are essential for accurate diagnosis and optimal therapy.

Few patients with acute suppurative parotitis (ASP) due to group B streptococcus (GBS) have been documented. Limited data on clinical and microbiological features and infectious route are available. We present a 21-day-old boy with invasive GBS disease manifesting as ASP. The patient was admitted because of irritability, fever, and erythematous swelling over the right parotid area. No purulent material exuded from the Stensen’s duct. Ultrasonography and computed tomography of the neck showed findings indicative of ASP. On the day after admission, blood culture yielded GBS. The isolate was determined as GBS serotype Ia and sequence type-23, and the patient was successfully treated with intravenous ampicillin for 10 days. A review of the literature revealed 11 GBS ASP infants including ours with age at onset between 13 days and 12 weeks. All infants had bacteremia while pus from the Stensen’s duct was detected in only one case. This finding remarkably contrasts with ASP caused by pathogens other than GBS, where the infection usually spreads via a retrograde route from Stensen’s duct. The present case and literature review indicate GBS ASP primarily arises from bloodstream infection, and that ASP should be included in an infectious focus as late onset GBS disease.

Acute Neonatal Suppurative Parotitis Due to Co-Infection by Non-Typable Beta-Hemolytic Streptococci and Escherichia coli: A Case Report

Neonatal suppurative parotitis (NSP) is a very rare disease of the salivary glands, usually involving the parotids. It is mostly due to Staphylococcus aureus bacterial infection among patients with predisposing factors, and management mainly relies on hydration and intravenous antibiotics with an excellent prognosis. Herein, we present a case of an 11-day-old female baby who presented with left periauricular edema and tenderness associated with fever that was later diagnosed as NSP due to both non-typable beta-hemolytic streptococci and Escherichia coli. Antibiotics therapy (vancomycin and gentamicin) was started, and the patient recovered completely after nine days. The CAse REport (CARE) guidelines were followed for reporting our case. Our case reiterates the fact that NSP should be in the differential diagnosis of any neonate presenting with fever and parotid area swelling. Prompt diagnosis is necessary for early management with antibiotics and to avoid complications.

Group B streptococcal neonatal parotitis

Acute neonatal parotitis (ANP) is a rare condition, characterised by parotid swelling and other local inflammatory signs. The most common pathogen is Staphylococcus aureus, but other organisms can be implicated. We describe the case of a 13-day-old term newborn, previously healthy, with late-onset group B Streptococcus (GBS) bacteraemia with ANP, who presented with irritability, reduced feeding and tender swelling of the right parotid. Laboratory evaluation showed neutrophilia, elevated C reactive protein and procalcitonin, with normal serum amylase concentration. Ultrasound findings were suggestive of acute parotitis. Empiric antibiotic therapy was immediately started and adjusted when culture results became available. The newborn was discharged after 10 days, with clinical improvement within the first 72 h. Although S. aureus is the most common pathogen implicated in ANP, GBS should be included in the differential diagnosis.

Bilateral acute neonatal suppurative parotitis: A rare finding in neonatal age

Acute suppurative parotitis is a rare entity in neonates. Bilateral involvement is extremely rare. Low birth weight, prematurity, gavage feeding, dehydration, sepsis are all known risk factors. Staphylococcus aureus is the most common organism, other organisms responsible for parotitis are streptococcus, E. coli, pseudomonas and klebsiella. We report a neonate suffering from bilateral acute suppurative parotitis with an unusual causative association. CPAP and its association for acute suppurative parotitis has been proposed.

Acute Neonatal Parotitis with Late-Onset Septic Shock due to Streptococcus agalactiae

Acute neonatal parotitis (ANP) is a very rare disease. Most cases are managed conservatively; early antibiotics and adequate hydration may reduce the need for surgery. The most common cause of ANP is Staphylococcus aureus. We report a rare case of acute neonatal parotitis with late-onset septic shock due to Streptococcus agalactiae. The diagnosis was confirmed with ultrasound and isolation of Streptococcus agalactiae from blood culture. The patient was treated successfully with 10 days of intravenous antibiotics and supportive measures. Despite being rare, streptococcal ANP should be considered in the etiological diagnosis of neonatal sepsis. Early diagnosis and appropriate antibiotic might prevent serious complications.

Methicillin-resistant Staphylococcus aureus as a cause of neonatal suppurative parotitis: a report of two cases and review of the literature

Suppurative parotitis is an uncommon entity identified in newborns. While Staphylococcus aureus has been frequently identified as the causative pathogen among the few patients diagnosed with neonatal suppurative parotitis (NSP), there has only been one prior case described in the literature that was due to methicillin-resistant Staphylococcus aureus (MRSA). Because of its virulence, MRSA presents new and substantial challenges for the surgeon; we describe two cases of NSP caused by MRSA and the subsequent surgical intervention necessitated for cure. We also include a review of all cases of NSP described in the English-language literature.

Relief from cluster headaches following extraction of an ipsilateral infected tooth

A 60-year-old man with a 7-year history of cluster headaches was seen by an oral surgeon for evaluation of pain in the left upper second molar ipsilateral to the side affected by the headaches. During extraction of the tooth, infection, decay, and inflammation were discovered. Since the extraction in November 2008, the patient has experienced one episode of cluster headaches as of April 2013.

Neonatal suppurative parotitis over the last 4 decades: report of three new cases and review

BACKGROUND

Neonatal suppurative parotitis is a rare disease. Only 32 cases were reported in the English-language literature between 1970 and 2004.

METHODS

We searched Medline for acute, neonatal, bacterial, suppurative, parotitis, facial, preauricular swelling starting from 1970, limiting our search to the English-language literature. We reviewed all the reported cases together with three more managed in our department.

RESULTS

We identified nine new cases since 2004. The total number of patients reviewed was 44, including our patients. Most of them were male (77%). The majority developed unilateral inflamed parotid swelling (77%) and exuded pus from the ipsilateral Stensen duct. Fever was seen in fewer than half of them (47%). Premature babies constituted a third of the patients. Staphylococcus aureus was the leading causative agent (61%). Most patients responded well to conservative treatment with antibiotics (77%). The most frequently used combination of antibiotics was an anti-staphylococcal agent with either an aminoglycoside or a third-generation cephalosporin. A minority required surgical drainage. No deaths were reported in the group studied after 1970.

CONCLUSION

Neonatal suppurative parotitis is rare but easy to diagnose and if readily treated with appropriate antibiotics the outcome is excellent.

Monolateral suppurative parotitis in a neonate and review of literature

OBJECTIVES

Neonatal suppurative parotitis is a rare condition characterized by swelling, pain, and erythema over the affected gland. Antimicrobials and adequate hydration are an essential part of treatment. Surgical intervention is reserved for organized abscesses and for infections not responding to medical management.

METHODS

A case report and review of the literature.

RESULTS

Only few case reports and case series are reported in literature on neonatal parotitis. Transmission of bacteria seems to occur mainly by ascending spread through Stensen's duct, or by hematogenous spread from a distant focus. Dehydration, low birth weight, immune suppression, ductal obstruction, oral trauma and structural abnormalities of the parotid gland are recognised as risk factors. The most common pathogen is Staphylococcus aureus. Other less frequent agents are other Gram-positive cocci, Gram-negative bacilli and rarely anaerobic bacteria. Advances in antimicrobial therapy have improved both outcome and prognosis.

CONCLUSIONS

Thanks to the prompt antibiotic treatment complications are now drastically reduced. Ultrasound examination may help in the diagnosis and monitoring of clinical course.

Neonatal parotid gland enlargement: Is it suppurative parotitis? A case report

Background:

Acute suppurative parotitis (ASP) is a rare finding in the neonate. It is commonly caused by S. aureus but other bacterial isolates may be emerging. Effective treatment includes prompt diagnosis, parenteral antibiotics and supportive measures such as rehydration and bimanual gland massage.

Case Report:

This case report describes an extremely premature female infant with a complicated post-natal course who presented with unilateral swelling of the parotid region. Diagnostic workup revealed purulent exudate from Stensen’s duct and ultrasound findings consistent with parotitis. Culture of the exudate showed growth of Staphylococcus aureus and Enterococcus species. The patient responded well to a ten-day antibiotic course and supportive measures.

Conclusions:

ASP, though rare, should be considered in the differential diagnosis of a neonatal parotid swelling since early and prompt diagnosis prevents morbidity and complications.

[Acute bacterial parotitis in infants under 3 months of age: a retrospective study in a pediatric tertiary care center]

BACKGROUND

Acute bacterial parotitis is a rare infectious disease in infants under 3 months of age.

OBJECTIVES

To describe the clinical characteristics and the course of acute bacterial parotitis in infants less than 3 months old.

PATIENTS AND METHODS

Infants under 3 months of age, hospitalized at Robert Debré university hospital, Paris, France, between January 2005 and December 2009 for acute bacterial parotitis, were included in a retrospective study.

RESULTS

Five infants less than 3 months of age were included in this study, for a frequency of 2.5/1000 hospitalizations in this age group. All were born at term, 4 of 5 were male. Three of the 5 patients had specific clinical signs of parotitis on admission. One patient had septic shock on admission. The ultrasound confirmed the parotitis in all cases. No parotid abscess was demonstrated on imaging. All patients had at least one abnormal inflammatory biological test (WBC, CRP, PCT). Bacteria were identified in 4 of 5 cases: Staphylococcus aureus was isolated in the pus culture of the Stenon duct in 2 patients and a group B Streptococcus was isolated from blood culture of 2 other patients. The duration of intravenous antibiotic therapy varied from 4 to 13 days, and the total duration of antibiotic therapy was between 10 and 16 days. No surgical procedures were needed.

CONCLUSION

Acute bacterial parotitis in infants under 3 months of age might be associated with localized infections due to S. aureus, but also with a more severe clinical presentation due to group B streptococcus infection. Early diagnosis and appropriate antibiotic therapy might prevent the progression to serious complications.

A 3-day-old boy with a right preauricular swelling

A 3-day-old boy was admitted for right preauricular swelling. Examination showed a toxic looking neonate with poor neonatal reflexes. There was erythema and swelling of 4 × 3 cm at the level of the right cheek. Laboratory investigation pointed to a bacterial infection. With parenteral antibiotics, the lesion resolved completely.

Acute Suppurative Neonatal Parotitis: Case Report

Neonatal suppurative parotitis is very rare. One review of the English-language literature spanning 35 years found only 32 cases. Most cases are managed conservatively with antibiotic therapy; early antibiotic treatment reduces the need for surgery. The predominant organism is Staphylococcus aureus. We report a new case of neonatal suppurative parotitis in a 3-week-old boy. The patient was diagnosed on the basis of parotid swelling, a purulent exudate from a Stensen duct, and the growth of pathogenic bacteria in culture. He responded well to 9 days of intravenous antibiotic therapy. We also discuss the microbiologic and clinical patterns of this disease.

Parotiditis aguda neonatal por Streptococcus agalactiae

We report two cases of group B streptococcal acute neonatal parotitis. Both patients showed late-onset infections in association with acute parotid swelling, without cellulitis or purulent drainage from Stensen's duct. Neither of the infants had meningitis, and Streptococcus agalactiae was isolated from blood cultures. Differential diagnosis with cellulitis-adenitis syndrome was based on clinical manifestations with supporting radiographic findings, which revealed parotid swelling with increased vascularization. Both infants were treated with a 2-week-course of intravenous cefotaxime, with complete recovery. Although the most common cause of acute neonatal bacterial parotitis is Staphylococcus aureus, Streptococcus agalactiae should be included in the differential diagnosis, especially in infants with late-onset sepsis.

Healthcare-associated infections in neonatal units: lessons from contrasting worlds

Neonatal intensive care units are vulnerable to outbreaks and sporadic incidents of healthcare-associated infections (HAIs). The incidence and outcome of these infections are determined by the degree of immaturity of the neonatal immune system, invasive procedures involved, the aetiological agent and its antimicrobial susceptibility pattern and, above all, infection control policies practised by the unit. It is important to raise awareness of infection control practices in resource-limited settings, since overdependence upon antimicrobial agents and co-existing lack of awareness of infection control is encouraging the emergence of multi-drug-resistant nosocomial pathogens. We reviewed 125 articles regarding HAIs from both advanced and resource-limited neonatal units in order to study risk factors, aetiological agents, antimicrobial susceptibility patterns and reported successes in infection control interventions. The articles include surveillance studies, outbreaks and sporadic incidents. Gram-positive cocci, viruses and fungi predominate in reports from the advanced units, while Gram-negative enteric rods, non-fermenters and fungi are commonly reported from resource-limited settings. Antimicrobial susceptibility patterns from surveillance studies determined the empirical therapy used in each neonatal unit. Most outbreaks, irrespective of the technical facilities available, were traced to specific lack of infection control practices. We discuss infection control interventions, with special emphasis on their applicability in resource-limited settings. Cost-effective measures for implementing these interventions, with particular reference to the recognition of the role of the microbiologist, the infection control team and antibiotic policies are presented.

[Neonatal acute suppurative parotitis]

Acute suppurative parotitis is highly uncommon in neonates. Approximately 100 cases have been reported in the literature. Dehydration and prematurity are important predisposing factors. Diagnosis is based on clinical signs. White blood cell count and parotid ultrasonography are useful. The most commonly isolated causative organism is Staphylococcus aureus. Initial treatment consists of antistaphylococcal empiric antimicrobial therapy for 7-10 days. The prognosis is good. The illness is not usually associated with recurrences. We describe two 12-day-old newborn infants who presented with fever, unilateral swelling of the parotid region with erythema, warmness and pain, and purulent discharge from Stensen's duct. We also provide a literature review.

Acute neonatal suppurative parotitis: case reports and review

We describe two cases of neonatal suppurative parotitis caused by Staphylococcus aureus. Only 32 cases of neonatal suppurative parotitis (72% male) have been described in the English literature in the last 35 years. Thirty-eight percent were premature babies, only 41% were febrile and the causative agent in most cases was S. aureus. Recovery was achieved in 78% of the patients with antibiotic therapy without drainage.

Suppurative parotitis caused by anaerobic bacteria in newborns

Staphylococci are the usual bacterial etiology of suppurative parotitis in newborns. This report describes for the first time recovery of anaerobic bacteria from aspirates of the infected gland in two infants with suppurative parotitis. Peptostreptococcus intermedius and Prevotella melaninogenica were isolated from one child and Prevotella intermedia from the other patient. Complete recovery occurred after 4 weeks of antimicrobial therapy.
