BACKGROUND: Infections due to Mycobacterium tuberculosis, Burkholderia pseudomallei and non-typhoidal Salmonella cause significant morbidity and mortality throughout the world. These intracellular pathogens share some common predisposing factors and clinical features. Co-infection with two of these organisms has been reported previously but, to our knowledge, this is the first time that infection with all three has been reported in one person.

CASE PRESENTATION: In September 2010, a 58-year-old diabetic Malaysian male presented with fever and a fluctuant mass on the right side of his neck. B. pseudomallei was isolated from an aspirate of this lesion and there was radiological evidence of disseminated infection in the liver and spleen. The recurrence of clinical symptoms over ensuing months prompted further aspiration and biopsy of a cervical abscess and underlying lymph nodes. Salmonella enterica serovar Stanley and then M. tuberculosis were identified from these specimens by culture and molecular methods. The patient responded to targeted medical management of each of these infections.

CONCLUSION: In endemic settings, a high index of suspicion and adequate tissue sampling are imperative in identifying these pathogenic organisms. Diabetes was identified as a predisposing factor in this case while our understanding of other potential risk factors is evolving.

Fulltext Sarcocystis nesbitti causes acute, relapsing febrile myositis with a high attack rate: description of a large outbreak of muscular sarcocystosis in Pangkor Island, Malaysia, 2012

From the 17th to 19th January 2012, a group of 92 college students and teachers attended a retreat in a hotel located on Pangkor Island, off the west coast of Peninsular Malaysia. Following the onset of symptoms in many participants who presented to our institute, an investigation was undertaken which ultimately identified Sarcocystis nesbitti as the cause of this outbreak.

Fulltext Antibiotics in surgical wards: use or misuse? A newly industrialized country's perspective

INTRODUCTION: Studies exploring the appropriateness of therapeutic antibiotic use among surgical patients are limited, particularly in developing countries. Therefore, the aim of our study was to determine the appropriateness of antibiotics prescribed in a surgical setting in Malaysia.
METHODOLOGY: A prospective observational study was conducted in two surgical wards at a tertiary hospital in Malaysia from November 2012-July 2013. Data was collected using a case report form. The appropriateness of antibiotic therapy was based on compliance with either the Malaysian National Antibiotic Guidelines 2008 or International Clinical Practice Guidelines and determined by an expert panel (consisting of two infectious disease consultants and a pharmacist).
RESULTS: Over the study period, a total of 593 antibiotic courses were prescribed for 129 patients (4.6±3.4 antibiotics/patient). Only 34 (26.4%) patients received appropriate antibiotic therapy, whilst 95 (73.6%) patients received at least one course of inappropriate antibiotic therapy. The prevalence of inappropriate antibiotic use was 214 (66.3%) and 55 (42.0%) for prophylactic and therapeutic purposes, respectively. The most common causes of inappropriate prophylactic antibiotics were inappropriate timing 20 (36.4%) and inappropriate duration of prophylaxis 19 (34.5%). In cases of inappropriate timing, 9 (45%) were administered too late while 6 (30%) were too early. In contrast, inappropriate choice of antibiotics (42.1%) and inappropriate indication (40.7%) were the most common reasons encountered for inappropriate therapeutic antibiotics.
CONCLUSION: Our study suggests considerable inappropriate use of both prophylactic and therapeutic antibiotics in the surgical wards; highlighting an urgent need for antibiotic stewardship initiatives in this setting.

Fulltext Outbreak of human infection with Sarcocystis nesbitti, Malaysia, 2012

An outbreak of fever associated with myalgia and myositis occurred in 2012 among 89 of 92 college students and teachers who visited Pangkor Island, Malaysia. The Sarcocystis nesbitti 18S rRNA gene and sarcocysts were obtained from muscle tissues of 2 students. Our findings indicate emergence of S. nesbitti infections in humans in Malaysia.
