Multiple bilateral renal abscesses in a previously healthy young patient

Tang RY, Cheong BM

Med J Malaysia, 2017 08;72(4):250-251.
PMID: 28889140 MyJurnal

The incidence of renal abscesses is not common. Patients usually have risk factors like diabetes mellitus or an underlying condition which predisposes to urinary tract infections. We report a case of a previously healthy young girl with multiple bilateral renal abscesses. Ultrasonography revealed multiple renal abscesses with a possible differential diagnosis of polycystic kidney disease with infected cysts. No renal calculi were seen. CT-scan of kidneys confirmed the diagnosis. Blood and urine cultures were repeatedly negative. She was treated with two weeks of intravenous antibiotics followed by another four weeks of oral Ciprofloxacin. No surgical intervention was carried out. Repeated ultrasound at six months showed complete resolution of all the renal abscesses.

Burkholderia cepacia: a rare cause of bacterial keratitis

Ibrahim M, Yap JY

BMJ Case Rep, 2018 Apr 25;2018.
PMID: 29695396 DOI: 10.1136/bcr-2018-224552

We describe the first clinical case of Burkholderia cepacia keratitis registered in Southeast Asia. A man in his mid-70s with underlying poorly controlled diabetes mellitus came with complaints of painful red left eye for 4 days. This was accompanied with photophobia and blurring of vision after being injured by a wooden particle while cutting grass. Slit-lamp examination showed a paracentral anterior corneal stromal infiltrates with overlying epithelial defect. Culture of the corneal smear isolated B. cepacia that was sensitive to ceftazidime, meropenem and bactrim (trimethorprim and sulfomethoxazole). Topical ceftazidime was given intensively to the patient and the infection resolved after 6 weeks of treatment.

Fulltext Melioidotic osteomyelitis treated with antibiotic-calcium hydroxyapatite composite: case report with four-year follow-up

Melioidosis is caused by an infection by Burkholderia pseudomallei. Osteomyelitis is a recognised manifestation of melioidosis but Burkholderia pseudomallei is a relatively rare aetiological agent in musculoskeletal infections. We report a 32-year-old diabetic man with septicaemia due to melioidotic infection of the spleen, liver and distal femur. The osteomyelitis relapsed despite being treated with the standard radical debridement and insertion of gentamycinimpregnated polymethylmetacrylate (PMMA) beads, followed by an optimal antibiotic therapy. The PMMA-gentamycin beads were then removed. The bone defect was debrided and packed with calcium hydroxyapatite blocks filled with ceftazidime powder. The osteomyelitis was successfully treated and the patient remained free of infection four years postoperatively. Computed tomography demonstrated successful incorporation of the calcium hydroxyapatite into host bone.

Fulltext Bruton's agammaglobulinaemia in a child presenting with cryptococcal empyema thoracis and periauricular pyogenic abscess

PMID: 8781652

We describe here a case of cryptococcal empyema thoracis and periauricular pyogenic abscess in a child with Bruton's agammaglobulinaemia. The cryptococcal empyema thoracis was treated with intravenous amphotericin B and intravenous fluconazole for six weeks followed by oral fluconazole. The pyogenic periauricular abscess was surgically drained and treated with intravenous ceftazidime and cloxacillin for two weeks. He also received monthly intravenous immunoglobulin.

PMID: 20531205 DOI: 10.1097/ICL.0b013e3181e3efa3

PURPOSE: The aim of this study is to evaluate the role of real-time polymerase chain reaction (PCR) and conventional bacterial culture methods in the detection of Pseudomonas aeruginosa in contact lens-induced severe, partially treated corneal ulcers referred to a tertiary center.
METHODS: The study duration was 6 months. All patients with contact lens-related corneal ulcer, requiring admission during the study period were recruited. Samples from corneal scrapings were simultaneously sent at the time of admission for PCR and culture testing. An in-house real-time PCR was developed to detect the P. aeruginosa lasA gene. The results of PCR and culture were compared using McNemar's chi2 test.
RESULTS: Ten patients were recruited. The mean age was 33 years (20-45 years). All the patients had contact lens-related keratitis (>4 mm) of which eight (80%) were found positive for P. aeruginosa by PCR or culture. There was no significant difference between PCR and culture in detecting P. aeruginosa (P<0.05).
CONCLUSIONS: PCR is, at least, as good as conventional cultures in detecting P. aeruginosa. It is a rapid assay as compared with culture, and early detection enables prompt treatment thus reducing the destructive effect of the organism on the cornea.

Single-daily ceftriaxone plus amikacin versus thrice-daily ceftazidime plus amikacin as empirical treatment of febrile neutropenia in children with cancer

PMID: 11168867

OBJECTIVE: Empirical antibiotic treatment for febrile neutropenic patients has been the mainstay of treatment for many years. Beta-lactam antibiotics and aminoglycosides have been the most frequently used drug combination. The purpose of this study was to evaluate the efficacy, safety, tolerance and costs of single-daily ceftriaxone plus amikacin versus thrice-daily dose of ceftazidime plus amikacin.
METHODOLOGY: One hundred and ninety-one episodes of fever and neutropenia in 128 patients from October 1997 to December 1998 were included in a prospective, open-label, single-centre study. Patients were randomly assigned to either treatment group and evaluated as successes or failures according to defined criteria. Daily assessments were made on all patients and all adverse events recorded. Univariate and multivariate analysis of outcomes and a cost analysis were carried out.
RESULTS: There were 176 evaluable patient-episodes with 51.1% in the single-daily ceftriaxone-amikacin group and 48.9% in the ceftazidime-amikacin group. There were 50 positive blood cultures: 12 Gram-positive bacteria, 33 Gram-negative bacteria and five fungi. Pseudomonas aeruginosa (P. aeruginosa) accounted for 14% of total isolates. The overall success rate was 55.5% in the ceftriaxone group compared to 51.2% in the ceftazidime group (P = 0.56). Mean time to defervescence was 4.2 days in the single-daily group and 4.3 days in the thrice-daily group. There were nine infection-related deaths; five in the single-daily ceftriaxone group. The daily cost of the once-daily regime was 42 Malaysian Ringgit less than the thrice-daily regime. There was a low incidence of adverse effects in both groups, although ototoxicity was not evaluable.
CONCLUSIONS: The once-daily regime of ceftriaxone plus amikacin was as effective as the 'standard' combination of thrice-daily ceftazidime and amikacin with no significant adverse effects in either group. The convenience and substantial cost benefit of the once-daily regime will be particularly useful in developing countries with limited health resources and in centres with a low prevalence of P. aeruginosa.
