PMID: 27326956 MyJurnal

Symptomatic bronchial artery aneurysm warrants urgent intervention. It has a known association with pulmonary infection caused by Staphylococcus aureus. We hereby report an elderly lady with a ruptured left superior bronchial artery mycotic aneurysm. She was in the early stages of treatment for a left lung abscess. She had multiple episodes of haemoptysis following which she underwent a left lower lobectomy. Presentation of lung abscess with a concurrent ruptured mycotic aneurysm warrants early surgical intervention and can be curative as seen in this case.

Reddy SC, Sharma HS, Mazidah AS, Darnal HK, Mahayidin M

Int J Pediatr Otorhinolaryngol, 1999 Jun 15;49(1):81-6.

PMID: 10428409

Orbital complications due to ethmoiditis are not uncommon in children. However, they are very rare in infants. A case of orbital abscess due to acute ethmoiditis in a 10 days old boy is reported. Causative microorganisms isolated from the operated specimen were Staphylococcus aureus and aspergillosis. Successful outcome was achieved following antimicrobial therapy, external ethmoidectomy, and surgical drainage of the abscess. The aetiopathogenesis and management of this clinical entity is discussed, with a brief review of the literature.

Bilateral orbital cellulitis due to Neisseria gonorrhoeae and Staphylococcus aureus: a previously unreported case

Raja NS, Singh NN

J Med Microbiol, 2005 Jun;54(Pt 6):609-611.

PMID: 15888472 DOI: 10.1099/jmm.0.46031-0

Cellulitis of the orbit is a common cause of proptosis in children, and also frequently arises in the elderly and the immunocompromised. The condition is characterized by infection and swelling of the soft tissues lining the eye socket, pushing the eye ball outwards and causing severe pain, redness, discharge of pus and some degree of blurred vision. There is a small risk of infection spreading to the meninges of the brain and causing meningitis. This paper reports the case of an adult in whom polymicrobial bilateral orbital cellulitis had developed due to Staphylococcus aureus and Neisseria gonorrhoeae infection. N. gonorrhoeae infections are acquired by sexual contact. Although the infection may disseminate to a variety of tissues, it usually affects the mucous membranes of the urethra in males and the endocervix and urethra in females. To the authors' knowledge this is the first report of polymicrobial bilateral orbital cellulitis due to S. aureus and N. gonorrhoeae in medical literature.

Genetic variation among methicillin-resistant Staphylococcus aureus isolates from cancer patients in Saudi Arabia

Alreshidi MA, Alsalamah AA, Hamat RA, Neela V, Alshrari AS, Atshan SS, et al.

Eur J Clin Microbiol Infect Dis, 2013 Jun;32(6):755-61.

PMID: 23318757 DOI: 10.1007/s10096-012-1801-9

One hundred and twenty methicillin-resistant Staphylococcus aureus (MRSA) isolated from cancer and non-cancer patients in Saudi Arabia were investigated for antibiotic resistance, virulence determinants and genotypes. The majority of MRSA isolates from cancer (n = 44, 73.3 %) and non-cancer patients (n = 34, 56.7 %) were multi-resistant to more than four classes of antibiotics. Virulence gene profiling showed that all strains were commonly positive for adhesin genes, except ebps and bbp genes, which were not detected in any isolate. Although the presence of adhesin genes varied slightly among MRSA isolates from cancer and non-cancer patients, these variations were not found to be statistically significant. In contrast, the presence of the toxin genes seb, sec, seg and sei was significantly elevated in MRSA strains isolated from cancer patients. Multilocus sequence typing (MLST) detected six and nine sequence types (STs) among isolates from cancer and non-cancer patients, respectively. Using spa typing, 12 and 25 types were detected, including four new types. The ability of different MRSA clones to become multi-resistant and their ability to acquire different virulence factors may contribute to their success as pathogens in individual groups of patients.

PMID: 29138666 DOI: 10.11604/pamj.2017.28.30.13544

We report a case study on a patient who presented with low back and thigh pain of one month duration. He was eventually diagnosed with left thigh pyomyositis. Tissue from thigh grew Staphylococcus aureus. With commencement of antibiotics and surgical drainage, patient made recovery despite prolonged hospital stay. The underlying mechanism of the extensive abscess accompanied by lack of systemic symptoms; is related to relative immunocompromised state of having underlying diabetes mellitus.

Fulltext Clinical characteristics and outcomes of paediatric orbital cellulitis in Hospital Universiti Sains Malaysia: a five-year review

Mohd-Ilham I, Muhd-Syafi AB, Khairy-Shamel ST, Shatriah I

Singapore Med J, 2020 Jun;61(6):312-319.

PMID: 31598730 DOI: 10.11622/smedj.2019121

INTRODUCTION: Limited data is available on paediatric orbital cellulitis in Asia. We aimed to describe demographic data, clinical presentation, predisposing factors, identified microorganisms, choice of antibiotics and management in children with orbital cellulitis treated in a tertiary care centre in Malaysia.

METHODS: A retrospective review was performed on children with orbital cellulitis aged below 18 years who were admitted to Hospital Universiti Sains Malaysia, Kelantan, Malaysia, between January 2013 and December 2017.

RESULTS: A total of 14 paediatric patients fulfilling the diagnostic criteria for orbital cellulitis were included. Their mean age was 6.5 ± 1.2 years. Boys were more likely to have orbital cellulitis than girls (71.4% vs. 28.6%). Involvement of both eyes was observed in 14.3% of the patients. Sinusitis (28.6%) and upper respiratory tract infection (21.4%) were the most common predisposing causes. Staphylococcus aureus (28.6%) was the leading pathogen. Longer duration of hospitalisation was observed in those infected with methicillin-resistant Staphylococcus aureus and Burkholderia pseudomallei. 10 (71.4%) patients were treated with a combination of two or three antibiotics. In this series, 42.9% had surgical interventions.

CONCLUSION: Young boys were found to be more commonly affected by orbital cellulitis than young girls. Staphylococcus aureus was the most common isolated microorganism. Methicillin-resistant Staphylococcus aureus and Burkholderia pseudomallei caused severe infection. Sinusitis and upper respiratory tract infection were the most common predisposing factors. A majority of the children improved with medical treatment alone. Our findings are in slight disagreement with other published reports on paediatric orbital cellulitis, especially from the Asian region.

PMID: 16114167

Tropical pyomyositis is a primary pyogenic infection of skeletal muscle, often caused by Staphylococcus aureus. The most common presentation of tropical pyomyositis is that of multiple acute abscesses with fever. Hepatitis is a rare manifestation of this disease. We report a case of tropical pyomyositis who presented with hepatic encephalopathy leading to initial diagnostic dilemma.

Fatal necrotizing pneumonia caused by Panton-Valentine leukocidin-producing hospital-acquired Staphylococcus aureus: a case report

Al-Talib H, Hasan H, Yean CY, Al-Ashwal SM, Ravichandran M

Jpn J Infect Dis, 2011;64(1):58-60.

PMID: 21266757

Panton-Valentine leukocidin (PVL) is a cytotoxin which causes leukocyte destruction and tissue necrosis. Although it is produced by fewer than 5% of Staphylococcus aureus strains, PVL-producing S. aureus is emerging as a serious problem worldwide. There has been a marked increase in the incidence of necrotizing lung infections with a very high mortality associated with these strains. This report describes a fatal case of hospital-acquired necrotizing pneumonia caused by PVL-positive methicillin-susceptible S. aureus in a patient with a brain tumor.
