Fulltext Melioidosis: an emerging infectious disease

Raja NS, Ahmed MZ, Singh NN

J Postgrad Med, 2005 Apr-Jun;51(2):140-5.
PMID: 16006713

Infectious diseases account for a third of all the deaths in the developing world. Achievements in understanding the basic microbiology, pathogenesis, host defenses and expanded epidemiology of infectious diseases have resulted in better management and reduced mortality. However, an emerging infectious disease, melioidosis, is becoming endemic in the tropical regions of the world and is spreading to non-endemic areas. This article highlights the current understanding of melioidosis including advances in diagnosis, treatment and prevention. Better understanding of melioidosis is essential, as it is life-threatening and if untreated, patients can succumb to it. Our sources include a literature review, information from international consensus meetings on melioidosis and ongoing discussions within the medical and scientific community.

Role of glucocorticoids in ototopical antibiotic-steroid preparations in the treatment of chronic suppurative otitis media

Indudharan R, Valuyeetham KA, Raju SS

Arch Med Res, 2005 Mar-Apr;36(2):154-8.
PMID: 15847949 DOI: 10.1016/j.arcmed.2004.12.012

It is conventional to use antibiotic-steroid combination eardrops, although the advantage of steroid combination has not been substantiated. The present prospective randomized comparative study is designed to assess the role of glucocorticoids in ototopical antibiotic-steroid preparations in the treatment of chronic suppurative otitis media (CSOM).

Jamaiah I, Rohela M, Ng TK, Ch'ng KB, Teh YS, Nurulhuda AL, et al.

Southeast Asian J. Trop. Med. Public Health, 2006 Jan;37(1):200-5.
PMID: 16771235

A hospital based retrospective study of the prevalence of snakebite cases at Hospital Kuala Lumpur was carried out over a five-year period from 1999 to 2003. A total of 126 snakebite cases were recorded. The highest admission for snakebites was recorded in 2001 (29 cases). The majority of cases were admitted for three days or less (79%). Most of the snakebite cases were reported in the 11-30 years age group (52%). The male:female ratio was 3:1. The majority of cases were Malaysians (80%, 101 cases). Of the non-Malaysians, Indonesians constituted the most (56%, 14 cases). Bites occurred most commonly on the lower limbs (49%), followed by upper limbs (45%) and on other parts of the body (6%). No fatal cases were detected and complications were scarce. In 60% (70 cases) the snake could not be identified. Of the four species of snakes that were identified, cobra (both suspected and confirmed) constituted the largest group (25%), followed by viper (10%), python (4%) and sea snake (1%). The most common clinical presentations were pain and swelling, 92% (116 cases). All patients were put on snakebite charts and their vital signs were monitored. Of the snakebite cases, 48% (61 cases) were treated with cloxacillin and 25% (32 cases) were given polyvalent snake antivenom.

Rhodococcus equi--an emerging human pathogen in immunocompromized hosts: a report of four cases from Malaysia

Puthucheary SD, Sangkar V, Hafeez A, Karunakaran R, Raja NS, Hassan HH

Southeast Asian J. Trop. Med. Public Health, 2006 Jan;37(1):157-61.
PMID: 16771229

Rhodococcus equi, a recognized pathogen in horses, is emerging as a human opportunistic pathogen, especially in immunocompromized hosts. We describe four immunocompromized patients who had serious R. equi infections with an overall mortality of 75%. The natural habitat of R. equi is soil, particularly soil contaminated with animal manure. Necrotizing pneumonia is the commonest form of infection but extrapulmonary infections, such as wound infections and subcutaneous abscess, have also been described in humans. R. equi is cultured easily in ordinary non-selective media. Large, smooth, irregular colonies appear within 48 hours. It is a facultative, intracellular, nonmotile, non-spore forming, gram-positive coccobacillus, which is weakly acid-fast staining and bears a similarity to diphtheroids. It forms a salmon-colored pigment usually after 48 hours incubation. A particular characteristic of this organism is that it undergoes synergistic hemolysis with some bacteria on sheep blood agar. R. equi may be misidentified as diphtheroids, Mycobacterium species, or Nocardia. In vitro R. equi is usually susceptible to erythromycin, ciprofloxacin, vancomycin, aminoglycosides, rifampin, imipenem and meropenem. The organism can be difficult to eradicate, making treatment challenging. Increased awareness of the infection may help with early diagnosis and timely treatment.

Role of Helicobacter pylori virulence factor and genotypes in non-ulcer dyspepsia

Tan HJ, Rizal AM, Rosmadi MY, Goh KL

J Gastroenterol Hepatol, 2006 Jan;21(1 Pt 1):110-5.
PMID: 16706821

The role of Helicobacter pylori (HP) in non-ulcer dyspepsia is debatable. Eradicating HP will help a small group of non-ulcer dyspeptic patients. However, it is unclear which subgroup of patients will benefit from eradication therapy. The aim of the present study was to compare the cagA and cagE status, as well as vacA genotypes, of HP in non-ulcer dyspeptic patients who responded successfully to eradication therapy compared with those patients who did not.

Providing guidelines and education is not enough: an audit of gentamicin use at The Royal Melbourne Hospital

Leong CL, Buising K, Richards M, Robertson M, Street A

Intern Med J, 2006 Jan;36(1):37-42.
PMID: 16409311

BACKGROUND: Aminoglycoside antibiotics are commonly prescribed for the treatment of Gram-negative infections. Appropriate dosing and therapeutic monitoring of aminoglycosides are important because these agents have a narrow therapeutic index.
AIM: To audit gentamicin use at our hospital, focusing on selection of the initial dose and therapeutic monitoring practices, and to compare the results against recommendations in the existing hospital aminoglycoside guidelines, which had recently been promoted to doctors.
METHODS: This audit included all inpatients receiving gentamicin at The Royal Melbourne Hospital from 1 February to 12 March 2004. The principal researcher checked the drug charts of all inpatients to identify those receiving gentamicin and collected data from the medical records and the pathology database. Doses were considered 'concordant' if the dose given was within the recommended dosing range +/-20 mg.
RESULTS: A total of 132 courses of gentamicin was included in the study. Gentamicin was prescribed for prophylaxis in 31.1% of courses. Thirty-six per cent of patients prescribed gentamicin were more than 65 years of age. Eighty-two per cent of the gentamicin used therapeutically was given as a single daily dose. Sixty-six per cent of gentamicin initial dosing was not in accordance with existing hospital guidelines. Seventy-seven per cent of gentamicin courses requiring therapeutic drug monitoring received such monitoring; however, in only 8.8% of these was the monitoring conducted according to guidelines.
CONCLUSION: Aminoglycoside prescribing practices at our hospital are suboptimal, despite ready access to prescribing guidelines. Provision of a guideline and education sessions with doctors do not necessarily lead to widespread adoption of recommended practices. We suggest that changes to hospital systems related to prescribing and monitoring of aminoglycosides are required.

Fulltext Community-acquired pneumonia in Malaysian patients: addition of macrolide and the use of BTS "curb" index to assess severity

Loh LC

Med J Malaysia, 2006 Mar;61(1):128-30.
PMID: 16708753

Sir, I read with interest the elegantly written CME article by Liam C K recently!. The choice of empiric antibiotic(s) in treating hospitalized adult patients with communityacquired pneumonia (CAP) is important as it can influence clinical outcomes 2. As correctly pointed out by the author, patients with CAP requiring hospitalization should, in addition to a ~-lactam stable antibiotic, be covered with a macrolide, to combat atypical pathogens such as Legionella pneumophila, Mycoplasma pneumoniae, and Chlamydia pneumoniae. Such is the recommendation from most foreign guidelines 3. 4. Here I wish to add our own observation based on a prospective study conducted between 2002 and 2004 of 141 adult patients with CAP hospitalized in Seremban Hospital in which we studied the clinical outcomes of patients treated empirically with and without a macrolide added to their ~-lactam stable antibiotic, recently published in Respirology 5.

Fulltext The clinical picture of neonatal infection with Pantoea species

Van Rostenberghe H, Noraida R, Wan Pauzi WI, Habsah H, Zeehaida M, Rosliza AR, et al.

Jpn J Infect Dis, 2006 Apr;59(2):120-1.
PMID: 16632913

Pantoea infections are uncommon in humans. Most reports have involved adults or children after thorn injuries. There are only a few reports of systemic infections with Pantoea. This is the first report of the clinical picture of systemic Pantoea spp. infection in neonates as observed during an outbreak in a neonatal intensive care unit caused by infected parenteral nutrition solutions. Even though detected early, the infections had a fulminant course, causing septicemic shock and respiratory failure. Pulmonary disease was prominent and presented mainly as pulmonary hemorrhage and adult respiratory distress syndrome. The organism was sensitive to most antibiotics used in neonatal intensive care units, but the clinical response to antibiotic therapy was poor. The fatality rate was very high: 7 out of 8 infected infants succumbed to the infection (87.5%).

Fulltext Parental knowledge, attitudes and antibiotic use for acute upper respiratory tract infection in children attending a primary healthcare clinic in Malaysia

Chan GC, Tang SF

Singapore Med J, 2006 Apr;47(4):266-70.
PMID: 16572235

INTRODUCTION: A study was carried out in a primary healthcare clinic in the Hulu Langat district of Malaysia to assess the parental knowledge, attitudes and antibiotic use for common childhood acute upper respiratory tract infection (URTI).
METHODS: A cross-sectional study involving 421 parents, who were surveyed by using an interviewer-administered questionnaire, from April to June 2001.
RESULTS: Approximately 59 percent of parents from this study believed that weather was the main cause of acute URTI of their children, 13 percent thought it was due to food, and only about 27 percent said it was caused by germs. Nearly 68 percent, 69 percent and 76 percent of them believed that antibiotics was helpful in treating the common cold, cough and fever, respectively. 29 percent of parents who thought that their child with acute URTI needed antibiotics were not prescribed with any. On the other hand, 17 percent believed that antibiotics were unnecessary when prescribed. 28 percent of parents had requested for antibiotics, and 93 percent received what they requested for their child with acute URTI. About 31 percent of parents who did not request any antibiotics claimed that private general practitioners habitually prescribed antibiotics. The antibiotic compliance was poor with only 74 percent completing the entire course, with 85 percent of them stopping once they improved symptomatically. 15 percent of parents gave "leftover" antibiotics, 24 percent gave "shared" antibiotics, and 5.5 percent bought antibiotics for their child with acute URTI without consulting a doctor.
CONCLUSION: This study shows that parents often have inadequate knowledge and misconceptions on antibiotic use for acute URTI in children. Improved parental education may reduce unnecessary antibiotic prescription and antimicrobial resistance in the community.

Fulltext Edwardsiella tarda septicemia with underlying multiple liver abscesses

Yousuf RM, How SH, Amran M, Hla KT, Shah A, Francis A

Malays J Pathol, 2006 Jun;28(1):49-53.
PMID: 17694959 MyJurnal

Edwardsiella tarda has recently been described as a member of the family Enterobacteriaceae. The genus Edwardsiella contains three species; E. hoshinae, E. ictaluri and E. tarda. Edwardsiella tarda is the only species which has been recognised as pathogenic to humans, especially in those with an underlying disease. The most common presentation is watery diarrhoea. Extra intestinal infections have been reported infrequently. Humans seem to be infected or colonised with Edwardsiella through ingestion or inoculation of a wound. This report is of a patient with multiple liver abscesses due to E. tarda who later developed bacterial peritonitis and septicaemic shock.

Fulltext Antibiotic prescribing for childhood febrile illness by primary care doctors in Malaysia

Teng CL, Hanafi NS, Ng CJ, Chia YC, Atiya AS

J Paediatr Child Health, 2006 Oct;42(10):612-7.
PMID: 16972968 DOI: 10.1111/j.1440-1754.2006.00937.x

AIM: Fever in children, a mostly benign and self-limiting illness, is often viewed with consternation by the care givers. It results in early consultation and excessive use of antipyretics and antibiotics. In this study, we document the prescribing practice of doctors from three primary care settings in Malaysia and identify the predictors of antibiotic prescription.
METHODS: Interview of care givers bringing febrile children (age = 12 years) to three primary care settings: public primary care clinics, private general practice clinics and a university-based primary care clinic.
RESULTS: Data from 649 children were analysed. Mean age of children 4.1 years and 55% were boys. One-third of the children had prior consultation for the same episode of fever. About 80% of the febrile children were diagnosed to have upper respiratory tract infection, viral fever and gastroenteritis. Overall antibiotic prescribing rate was 36.6% (public primary care clinic 26.8%, private general practice clinic 70.0% and university-based primary care clinic 32.2%). Independent predictors of antibiotic prescription were: clinic setting, longer duration of fever (>7 days), higher temperature (>38 degrees C) and the diagnosis of upper respiratory tract infections. After controlling for demographic and clinical factors, antibiotic prescription in private general practice clinic was seven times higher than public primary care clinic (odds ratio 7.1, 95% confidence interval 4.0-12.7), and 1.6 times higher than university-based primary care clinic (odds ratio 1.6, 95% confidence interval 1.0-2.5).
CONCLUSION: Differences in the patients' demographic and clinical characteristics could not adequately explain the high antibiotic prescribing rate in private general practice clinics. This inappropriately high antibiotic prescribing for febrile children in private general practice clinics is a suitable target for future intervention.

A study on the knowledge, attitudes and practices of Southeast Asian dermatologists in the management of atopic dermatitis

Chan YC, Tay YK, Sugito TL, Boediardja SA, Chau DD, Nguyen KV, et al.

Ann Acad Med Singap, 2006 Nov;35(11):794-803.
PMID: 17160196

INTRODUCTION: This study evaluated the knowledge, attitudes and practices of Southeast Asian dermatologists in the management of atopic dermatitis (AD).
MATERIALS AND METHODS: A questionnaire survey of 255 dermatologists in Indonesia, Malaysia, the Philippines, Singapore, Thailand and Vietnam.
RESULTS: Familiarity with diagnostic criteria varied considerably. The usage of moisturisers by the respondents from Vietnam and Indonesia was significantly less frequent than the other countries. Most respondents (91% to 100%) used topical corticosteroids in children with mild-to-moderately severe dermatitis. Some respondents in the Philippines (17% to 19%) and Vietnam (11% to 25%) only used topical corticosteroids for severe disease. For infected eczema, most respondents would prescribe systemic antibiotics for mild-to-moderate infection. A minority in the Philippines (14%) and Vietnam (11%) did so only for severe infection. The top 4 systemic antibiotics prescribed most frequently were: erythromycin, cloxacillin, cephalosporin and amoxicillin/clavulanic acid. In Indonesia, a large proportion of the respondents (47%) prescribed amoxicillin most frequently. The majority of respondents (60% to 100%) prescribed both sedating and non-sedating oral antihistamines. Most respondents used oral corticosteroids to treat severe AD. Some in Malaysia, Singapore and Vietnam used cyclosporin (7% to 58%), azathioprine (5% to 31%) and methotrexate (5% to 14%). With the exception of those in Singapore, the majority of respondents (71% to 97%) did not use phototherapy.
CONCLUSION: Familiarity with diagnostic criteria, the early and judicious use of moisturisers and topical corticosteroids, as well as the treatment of Staphylococcus aureus superinfection with penicillinase-stable antibiotics should be emphasised in this region.

Fulltext Use of gentamicin impregnated POP discs for antibiotic pouch dressing

Lau CP, Chee EK, Thirumal M

Med J Malaysia, 2006 Dec;61 Suppl B:32-6.
PMID: 17600990

Antibiotic pouch technique is commonly used due to the high local antibiotic concentration and moist environment for wound healing. We used locally made gentamicin impregnated Plaster of Paris discs in treating wounds with exposed deep structures like tendons and bones. Out of 22 patients treated with this method, 19 completed treatment. Granulation tissue formed quickly and effectively covered the exposed structures. All wounds either healed by secondary intention or became suitable for split skin grafting. Gentamicin impregnated Plaster of Paris disc pouch dressing is safe, cost saving, and effective for management of deep open wounds.

Cefepime monotherapy for treatment of febrile neutropenia in children

Ariffin H, Ai CL, Lee CL, Abdullah WA

J Paediatr Child Health, 2006 Dec;42(12):781-4.
PMID: 17096713

Empirical therapy for children with febrile neutropenia has traditionally consisted of combination antibiotics, usually a beta-lactam and an aminoglycoside. However, recent trends and international guidelines have now made monotherapy a feasible option in the management of this group of patients. We prospectively evaluated the efficacy and safety of cefepime monotherapy in our population of paediatric cancer patients with febrile neutropenia.

Fulltext A case of auricular myiasis in Malaysia

Rohela M, Jamaiah I, Amir L, Nissapatorn V

Southeast Asian J. Trop. Med. Public Health, 2006;37 Suppl 3:91-4.
PMID: 17547059

Many cases of myiasis have been reported in Malaysia. This is the second reported case of auricular myiasis caused by Chrysomya bezziana. The patient was a 41-year-old, mentally retarded, Orang Asli man. He was brought to the clinic by his mother with a complaint of pain and bleeding in his right ear for 3 days. On examination, blood and multiple maggots were seen packed in the external auditory canal of the right ear. A total of 39 live maggots were removed and maintained until they developed into 3rd instar larvae, which were later processed and identified as Chrysomya bezziana. The patient was discharged with amoxicillin 500 mg three times a day for 1 week.

Fulltext Over-prescription of antibiotics: both doctors and patients need education

Norsa'adah B

Med J Malaysia, 2007 Jun;62(2):181.
PMID: 18705463

Principally, there are two problems in prescribing . They are prescribing decision and prescribing writing process, which contribute to 39% and 61% of prescription problems respectively. The first type of problem has more serious consequences and may even cause mortality. In that study, the issue is the appropriateness of prescribing antibiotics for upper respiratory tract infections (URTI). Over-prescribing of antibiotics in primary health care, especially for respiratory tract diseases is a problem worldwide . There are concerns about the rising prevalence of antibiotic resistant bacteria, cost and the potentially harmful consequences of unnecessary prescription such as drug interaction and allergy.
