Parotid abscess is uncommon in neonates. It is frequently related to prematurity, prolonged gavage feeding and dehydration. We report a case of a late preterm infant who developed the classical manifestation of unilateral acute Staphylococcus aureus suppurative parotitis progressing to formation of abscess which responded to surgical drainage and antibiotic therapy.
A 38-year-old woman presented with right-sided parotid swelling, dry mouth and dry eyes of one year duration. Her Schirmer's test and sialometry were positive and histopathology showed lymphoplasmacytic infiltration. She also had concomitant normochromic , normocytic anaemia and mild haematuria. Her anti-nuclear antibody titre was also positive, 1:640, with a speckled pattern on immunofluorescence. We discuss the atypical presentation of systemic lupus erythematosus, particularly parotitis and secondary Sjogren's syndrome.
Facial nerve palsy with a parotid mass is usually associated with malignant neoplasm of parotid gland. Its occurrence as a complication of parotid abscess is extremely rare. A literature review revealed only 16 cases of facial nerve palsy associated with suppurative parotitis or parotid abscess were reported. We present a case of deep parotid abscess which is complicated by facial nerve dysfunction. Underlying neoplasia was excluded.
Introduction:Staphylococcus aureus is a Gram-positive staphylococci that form biofilms. Bacteria that dwell in bio-films tend to be highly resistant towards the action of antibiotics. S. aureus is a main cause of infections in the oral cavity such as angular cheilitis, endodontic infections, osteomyelitis of the jaw, parotitis and oral mucositis. Previous studies reported that S. aureus also spread to the other parts of the body through the circulatory system, which may lead to chronic infections. Hence the search for new antibacterial agents remains high and needs urgent attention to treat this problem. Plants offer a rich source of antimicrobial agents and bioactive compounds. In this study, aque-ous oil palm leaf extracts (OPLE) has been used as an alternative antibacterial agent against oral infections mainly caused by Staphylococcus aureus. Many studies report the potential use of oil palm leaf extracts in treating bacterial infections such as Escherichia coli, Salmonella sp., Staphylococcus aureus (isolated from other part of the body), Pseudomonas aeruginosa and Bacillus sp. Although previous studies have documented the antimicrobial properties of oil palm leaf extracts, to date no study has been reported on the effect of oil palm leaf extract on oral microbes. Methods: The agar diffusion method, minimum inhibitory concentration (MIC) and minimal bactericidal concen-tration (MBC) assay were conducted in order to observe the antibacterial activity of aqueous oil palm leaf extract. The crystal violet assay was used to determine the anti-biofilm activity of the extracts. Chlorhexidine and deionised distilled water were used as the positive and negative control respectively. For agar diffusion method, the diameter of inhibition zone was measured. Results: The inhibition zone of the tested bacteria was observed between 0-20mm. The MIC and MBC assay were used to know the lowest concentrations of the extract that inhibit the growth and killed the tested bacteria respectively. The MIC and MBC values for the tested bacteria were observed between 0-7.813mg/mL. While for anti-biofilm assays, OPLE aqueous extract acts as a potent anti-biofilm agent with dual actions, pre-venting and eradicating the biofilm of the tested bacteria. Conclusion: In conclusion, the tested plant extracts could serve as alternative natural antibacterial and anti-biofilm agent against oral infections.
Melioidosis is much less common in children than in adults. This study investigated the incidence, demographic characteristics, presenting symptoms and outcome of pediatric melioidosis in Pahang, Malaysia. This retrospective study included patients < or =18 years old with positive body fluid cultures for Burkholderia pseudomallei from January 2000 to June 2003. Data on culture results were obtained from 2 referral hospitals. The incidence of pediatric melioidosis was 0.68/100,000 population per year. Of the 13 patients identified during the study period, 10 were male; 9 were Malays, 2 were Indians and 2 were aborigines. The mean age of these patients was 9.5 +/- 5.4 years. None of the patients had a previous history of confirmed melioidosis or predisposing factors for infection. Localized melioidosis was the most common presentation (46.2%) followed by melioidosis with septic shock (38.4%). Among patients with localized melioidosis, head and neck involvement (83.3%) was the most common presentation (2 patients with cervical abscesses, 1 with submandibular abscesses and 2 with acute suppurative parotitis) and another patient had right axillary abscess. All of the patients with septic shock had pneumonia and 2 of them had multi-organ involvement. The mortality among patients with septic shock was 80% and death occurred within 24 h of admission in all cases. In contrast, no complications or death occurred among patients with localized melioidosis. Melioidosis with septic shock is less common than localized melioidosis in pediatric patients, but is associated with very high mortality.
