Diagnostic use of Burkholderia pseudomallei selective media in a low prevalence setting

Roesnita B, Tay ST, Puthucheary SD, Sam IC

Trans R Soc Trop Med Hyg, 2012 Feb;106(2):131-3.
PMID: 22112687 DOI: 10.1016/j.trstmh.2011.10.007

Routine use of selective media improves diagnosis of Burkholderia pseudomallei, but resources may be limited in endemic developing countries. To maximise yield in the relatively low-prevalence setting of Kuala Lumpur, Malaysia, B. pseudomallei selective agar and broth were compared with routine media for 154 respiratory specimens from patients with community-acquired disease. Selective media detected three additional culture-positive specimens and one additional melioidosis patient, at a consumables cost of US$75. Burkholderia pseudomallei was not isolated from 74 diabetic foot ulcer samples. Following careful local evaluation, focused use of selective media may be cost-effective.

PMID: 23749027

The diabetic foot with its many associated complications and presentations can provide a challenge in diagnosis and subsequent treatment. MRI, being increasingly available commonly, is now the main investigative modality. In particular, it is helpful in differentiating between neuroarthropathy and osteomyelitis and in cases where the latter is superimposed on the former. By being well versed in the interpretation of the images, the radiologist can make crucial contribution to the care and management of these patients.

Fulltext Malignant melanoma of the foot in patients with diabetes mellitus--a trap for the unwary

Hussin P, Loke SC, Noor FM, Mawardi M, Singh VA

Med J Malaysia, 2012 Aug;67(4):422-3.
PMID: 23082455

Melanomas on the foot are difficult to differentiate from diabetic foot ulcers (DFU). In particular, acral lentiginous and amelanotic melanomas have a high chance of being misdiagnosed. We present two patients with diabetes mellitus and malignant melanomas of the foot initially diagnosed as DFU. Both cases were treated with wide excision amputation and local dissection, without adjuvant chemotherapy or radiotherapy. Both patients remain disease-free up to the last follow-up visit. It is important to maintain a high index of suspicion and a skin biopsy should be done in any DFU with atypical features.

Med J Malaysia, 2011 Aug;66(3):234-8.
PMID: 22111447 MyJurnal

This study aimed to evaluate the impact of foot problems on health-related quality of life (HRQoL) in patients with diabetes in Malaysia. Short-Form 36 (SF-36) questionnaire was used to assess the HRQoL of 140 diabetic patients with foot problems attending outpatient diabetic foot clinic in a tertiary hospital, University Malaya Medical Centre. Their HRQoL were compared with 134 diabetic patients without foot problems attending the same clinic. The median score of all the eight SF-36 domains differed significantly between the two groups, where patients with foot problems having statistically significant lower scores. The two domains that were most severely compromised were components of the physical health: Physical Functioning and Role Physical domains. The SF-36 scale scores in diabetic patients with foot problems were also lower than those of the SF-36 norms for the Malaysian population. In conclusion, the results showed that diabetic foot problems negatively affect the patients' HRQoL in both physical and mental health aspects based on the SF-36.

Med J Malaysia, 2008 Mar;63(1):44-6.
PMID: 18935732 MyJurnal

Honey dressing has been used to promote wound healing for years but scanty scientific studies did not provide enough evidences to justify it benefits in the treatment of diabetic foot ulcers. We conducted a prospective study to compare the effect of honey dressing for Wagner's grade-II diabetic foot ulcers with controlled dressing group (povidone iodine followed by normal saline). Surgical debridement and appropriate antibiotics were prescribed in all patients. There were 30 patients age between 31 to 65-years-old (mean of 52.1 years). The mean healing time in the standard dressing group was 15.4 days (range 9-36 days) compared to 14.4 days (range 7-26 days) in the honey group (p < 0.005). In conclusion, ulcer healing was not significantly different in both study groups. Honey dressing is a safe alternative dressing for Wagner grade-II diabetic foot ulcers.

Chuah KH, Thong CL, Krshnan H, Chan L

Med J Malaysia, 2007 Mar;62(1):81-2.
PMID: 17682582 MyJurnal

Patients with poorly controlled diabetes mellitus have an increased risk of lower limb infection and gangrene. In Malaysia, they frequently present late and are often in septic shock with multi-organ dysfunction. We report on two patients who presented for lower limb amputation in a desperate attempt to control sepsis and save their lives. Both patients were classified as ASA 5. Both patients had successfully undergone surgery under low dose unilateral spinal anaesthesia. The anaesthetic management of these critically ill patients in view of limited resources is discussed.

PMID: 17042222

Infection plays a pivotal role in enhancing a diabetic foot at risk toward amputation. Effective antibiotic therapy against the offending pathogens is an important component of treatment of diabetic foot infections. Recognition of the pathogen is always difficult as the representative deep tissue sample for culture is surrounded by ulcer surface harbouring colonies of organisms frequently labelled as skin commensals. The emergent of resistant strains represents a compounding problem standing against efforts to prevent amputation. This study was undertaken to identify the pathogens associated with diabetic foot infection in terms of their frequency and sensitivity against certain commonly used antibiotics. Forty-four consecutive patients with open diabetic foot infections had wound swab taken for culture and sensitivity testing. Cultures positive were observed in 89% of the cases with Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeroginosa encountered in 20%, 14% and 14% of cases respectively. Mixed growths were isolated in 6% of cultures. All Staphylcoccus aureus isolates were resistant to Penicillin but 80% were sensitive to Erythromycin and Co-trimoxazole. Klebsiella pneumoniae isolates were sensitive to Methicillin and Gentamycin in 80% and 60% of cases respectively, and resistant to Ampicillin and Ceftazidime in 83% and 50% respectively. All Pseudomonas aeroginosa isolates were sensitive to Amikacin and Ciprofloxacin but 50% were resistant to Gentamycin. There was no single antibiotic possessing good coverage for all common organisms isolated from diabetic foot lesions. Staphylococcus aureus remains the predominant cause of diabetic foot infections followed by Klebsiela pneumonia and Pseudomonas aeroginosa. Most infections are monomicrobial. The emergence of multiresistant organisms is a worrying feature in diabetic foot infections.

PMID: 26248782 MyJurnal

INTRODUCTION: Patients suffering from diabetes mellitus (DM) frequently present with infected diabetic foot ulcers (DFU). This study was done to record the anatomical site and the grade of ulcers according to Wagner's classification and to culture the microorganisms from the ulcers and determine their antibiotic sensitivity.
MATERIALS AND METHODS: Prospective study was conducted on 77 diabetic patients who were admitted with DFU from June until December 2011. Patients with end stage renal failure, those who had previous vascular surgery on the involved limb, or hyperbaric oxygen or maggot therapy for the ulcers, or had unrelated skin diseases around the involved foot were excluded from the study. Specimens for culture were obtained by a sterile swab stick or tissue sample was taken from the wound with sterile surgical instruments.
RESULTS: Wagner's grade III and IV ulcers were most common. Majority of the ulcers involved toes (48%). Gram negative microorganisms were predominantly isolated (71.1%). Gram positive microorganisms were less frequently cultured (27.7%). Fungus was cultured from one sample (1.2%). Gram negative microorganisms were sensitive to aminoglycosides, cephalosporins or β-lactamase inhibitors. More than 40% were resistant to ampicillin. Gram positive microorganisms were sensitive to cloxacillin. MRSA were sensitive to vancomycin.
CONCLUSION: Empirical use of antibiotics should be curtailed to prevent development of drug resistant strains of microorganisms and MRSA. We suggest use of antiseptic solutions to clean the ulcers until antibiotic sensitivity report is available. Results of our altered treatment regimen we plan to publish in a later study.

Fulltext Factors related to adverse outcome in inpatients with diabetic foot

Harwant S, Doshi HK, Moissinac K, Abdullah BT

Med J Malaysia, 2000 Jun;55(2):236-41.
PMID: 19839152

Sixty inpatients with diabetic foot were studied prospectively at the Orthopaedic wards of Hospital Kuala Lumpur. Data was evaluated to document the patient profile and the factors that were associated with a major amputation (either above knee or below knee) of the lower limb. Factors that were associated with increased risk of amputation were a low education level, manual occupation, poor foot care, peripheral vascular insufficiency of the lower limb, insulin dependence, anaemia and leucocytosis. However only anaemia, leucocytosis and hyperglycaemia were statistically significant in predicting a more adverse surgical procedure. This study recommends that foot care awareness and practice is important. This can be effectively dealt with at specially organised, multi disciplinary Diabetic Foot Clinics.

Fulltext Are diabetic foot lesions precipitated by accidental trauma?

Doshi HK, Moissinac K, Harwant S

Med J Malaysia, 2001 Dec;56 Suppl D:29-33.
PMID: 14569763

Diabetic foot lesions may arise from frictional trauma due to tight or inappropriate footwear, repetitive stresses on parts of the foot, overlying bony prominence generated by walking and accidental trauma to the neuropathic foot. Many diabetics have been found to be unaware of their foot lesion, or know what the precipitating cause was. Based on the assumption that accidental trauma would affect the foot in a random fashion and result in lesions distributed evenly throughout the foot, a study was performed to determine whether foot lesions were distributed evenly or concentrated to certain areas of predilection. It was found that foot lesions were not evenly distributed but concentrated to certain areas of predilection. Even though relatively high proportion of the study population walked about in open slippers and barefeet, the study showed that accidental trauma was not a predominant precipitant of diabetic foot lesions. Diabetic foot lesions tend to occur as a result of cumulative, repetitive trauma to areas of prediliection rather than accidental trauma.

Pericardial abscess: The corollary of disseminated Methicillin-resistant Staphylococcus aureus following diabetic foot ulcer infection

Tan TL, Lim SH, Ruslan Mustapa M, Ganeswary R

Med J Malaysia, 2020 11;75(6):742-744.
PMID: 33219189

Methicillin-resistant Staphylococcus aureus (MRSA) purulent pericarditis, characterised by frank pus collection or microscopic pyogenic effusion in the pericardium represents the most serious form of pericardial infection. The route of MRSA acquisition in pericardial abscess commonly occurs via the blood stream infection and it is more commonly observed among immunocompromised individuals. To date, diabetic foot ulcer infection rarely disseminates and becomes a nidus for pericardial infection. Herein, we report an unusual case of MRSA pericardial abscess in a 44-year-old man who presented at Hospital Seri Manjung, Malaysia with cardiac tamponade. Past medical history indicated that he was recently treated for infected diabetic foot ulcer with MRSA bacteraemia one week earlier. Despite adequate pericardial drainage and extended parenteral vancomycin therapy, this case ended in fatality on day 42 of admission due to nosocomial infection. It is hoped that this report serves to increase the vigilance among clinicians that diabetic foot ulcer infections have the potential to progress to pericardial abscess in the presence of MRSA bacteraemia, although they may appear seemingly innocuous at presentation. Systemic vancomycin must be instituted promptly when MRSA bacteraemia is confirmed in order to circumvent the propagation of MRSA.

Ng BW, Muhammad Firdaus A, Mohd Syafiqq Al Hakim HR, Nur Sa'idah MS, Loi KW, Ong KC, et al.

Med J Malaysia, 2020 01;75(1):29-32.
PMID: 32008016

INTRODUCTION: Diabetic foot infection is often associated with high morbidity, disability and poor quality of life. This study focuses on the demography, the number of repetitive surgery and length of stay in hospital of patients with diabetic foot infection.
METHOD: This is a retrospective observational study. Patients who were admitted to the Orthopaedic ward of Hospital Segamat (HS), Johor, Malaysia from January 2016 to December 2018 and required surgical intervention were included in the study. Data was collected from the computer system of HS and medical notes of patients.
RESULTS: 35.6% of the total orthopaedic emergency surgeries performed were for patients with diabetic foot infection, 25% of the surgical procedures performed were major amputations of lower limb and 40% of the patients with diabetic foot infection required more than one surgical operation.
DISCUSSION: The demographics of the patients is consistent with the demographics of Malaysia where majority of them are Malays followed by Chinese, Indians and others. Despite being only 10% of total admission to the department, this group of patients contributed to 35.6% of the total emergency surgeries performed. The amputation rate in the centre is comparable to the other local studies. The average length of stay in hospital was found to be shorter compared to overseas due to different rehabilitation protocols.

Nik Hisamuddin NAR, Wan Mohd Zahiruddin WN, Mohd Yazid B, Rahmah S

Med J Malaysia, 2019 Oct;74(5):418-424.
PMID: 31649219

INTRODUCTION: The purpose of this study was to investigate the effect of hyperbaric oxygen therapy (HBOT) towards diabetic foot ulcer (DFU) patients in addition to the standard wound care management.
METHODS: Fifty-eight diabetic patients with ulcers at Wagner Grade 2 and above involved in this study after presented at two study centres of tertiary teaching hospitals. The assigned patients received conventional wound care with additional HBOT given at 2.4 ATA for 90 minutes. Patients in the control group who received conventional wound care only were treated and observed for 30 days. The progress of wound healing was observed and measured at day 0, 10, 20 and 30 of study. The data collected were analysed using SPSS software (ver. 22) to study the association of HBOT towards healing of the diabetic foot ulcers.
RESULTS: Repeated Measures ANOVA analysis with Greenhouse-Geisser correction indicated that the means of wound size over time points (Day 0, 10, 20 and 30) among patients under HBOT group were statistically significantly different [F(1,61)=30.86, p<0.001)] compared to conventional therapy group. Multiple logistic regression analysis showed that HBOT group has nearly 44 times higher odds to achieve at least 30% wound size reduction within the study period (95%CI: 7.18, 268.97, p<0.001).
CONCLUSION: The results obtained in this study indicated that as an adjunctive therapy to conventional wound care, HBOT affected the rate of healing in diabetic foot ulcers significantly in terms of wound size reduction when compared to administering the conventional wound care alone.

Fulltext Microbiology of diabetic foot infections in three district hospital in Malaysia and comparison with South East Asian Countries

Kow RY, Low CL, Ruben JK, Zaharul Azri WMZ, Mor Japar Khan ESK

Med J Malaysia, 2019 Oct;74(5):394-399.
PMID: 31649215

INTRODUCTION: Diabetic foot infection, a complication that is associated with lower-limb amputation, incurs a huge economic burden to the hospital and health care system of Malaysia. The bacteriological profile of pathogens in diabetic foot infections in Malaysia has been sparsely studied. We investigated the microbiology of diabetic foot infections in patients admitted to the district hospitals on the east coast of Malaysia.

METHODS: A retrospective analysis was conducted in three district hospitals (Hospital Kuala Lipis, Hospital Bentong and Hospital Raub) in Malaysia from 1st of January 2016 to 31st December 2016. The clinical specimens were cultured using Clinical and Laboratory Standards Institute (CLSI) guidelines. Antibiotic sensitivity testing to different antibiotics was carried out using the disc diffusion method.

RESULT: A total of 188 pathogens were isolated from 173 patients, with an average of 1.09 pathogens per lesion. Majority of the pathogens isolated were gram negative pathogens (73.4%). The most commonly isolated pathogens were Staphylococcus aureus (17.5%). This was followed by Klebsiella spp. (17%), Pseudomonas spp. (15.4%) and Proteus spp. (13.8%). Gram positive pathogens were sensitive to most of the antibiotics tested except penicillin and fusidic acid. Gram negative pathogens were sensitive to all antibiotics tested except ampicillin and amoxicillin/clavulanic acid. Amikacin provide coverage for all gram negative pathogens in DFI.

CONCLUSION: For the management of patient with infection in diabetic foot, the choice of antibiotic therapy depends on the sensitivity of the pathogens, the severity of the infection, the patient's allergies history, toxicity and excretion of the antibiotics.

Fulltext Alteration of foot temperature in diabetic neuropathy: is it another piece of puzzle?

Naicker AS, Roohi SA, Lee CS, Chan WH, Tay LS, Din XJ, et al.

Med J Malaysia, 2006 Feb;61 Suppl A:10-3.
PMID: 17042221

Poor glycaemic control and the duration of diabetes mellitus are known to accelerate development and progression of neuropathy. Diabetic co-morbidities: hypertension and hyperlipidaemia, have been postulated to associate with development of neuropathy. A diabetic foot with low temperature and frequent exposure to low temperature environment has recently been hypothesized to be at higher risk to develop early neuropathy. This cross-sectional study is undertaken to identify risk factors for diabetic neuropathy and the association between foot temperature and development of diabetic neuropathy by using simple clinical examination in the outpatient setting. From April 18, to April 30, 2005, universal sampling method was used to select 134 diabetic patients (type 1 or type 2 for >1 year) with peripheral neuropathy. Excluded are those with chronic alcoholism, drug-induced neuropathy, dietary history of vitamin B deficiency and family history of porphyria and hereditary sensorimotor neuropathy. The patient's duration of diabetes, glycaemic control status and the presence of co-morbids: hypertension and hyperlipidemia, were recorded. The temperature of the foot was measured by using thermo buddy. Of 134 patients representing Malaysian ethnic distribution with an equal number of males and females, 20.1% were in the age group of 61 to 65 years and, 85.1% and 67.9% belonged to lower socioeconomic and educational groups respectively. Associations between diabetic neuropathy and glycaemic control (p = 0.018) and duration of diabetes (p < 0.05) were significant. However, hypertension, hyperlipidaemia and low foot temperature were not significantly associated with development of diabetic neuropathy. Poor glycaemic control is significantly associated with diabetic neuropathy. Foot temperature alteration is merely an effect of autonomic neuropathy with a cold foot is attributed to co-existing peripheral arterial disease.

Fulltext Knowledge and attitude of nurses towards diabetic foot care in a secondary health care centre in Malaysia

Ng BW, Azhar AA, Azman MH, Sukri MS, Arvinder-Singh HS, Abdul Wahid AM

Med J Malaysia, 2020 07;75(4):391-395.
PMID: 32724000

INTRODUCTION: Nurses play a vital role in the care and prevention of ulcers in patients with diabetic foot. Patient education, prevention of ulcers and rehabilitation are some of the vital aspects that nurses provide on a daily basis. Thus, good knowledge and attitude of nurses towards diabetic foot ulcers and its care will ensure better patient care.

OBJECTIVES: The aim is to study the level of knowledge and attitude of nurses towards diabetic foot ulcers and its care in Hospital Segamat, Malaysia.

METHODS: A validated questionnaire was used between February 2019 to May 2019 covering area such as demography, predisposing factors of ulcer formation, characteristics of ulcers, complications of ulcers, and attitude towards diabetic foot care.

RESULTS: A total of 101 nurses took part and 57% of the participants scored poorly in the knowledge section of the questionnaire. In all 72% had scored poorly when asked regarding complications of diabetic foot ulcers; 49.5% of the nurses had positive attitude towards diabetic foot care; and 79.3% thought that care for diabetic foot ulcer is timeconsuming. Majority of them think that their colleagues are the main source of information. All demographic variables were deemed to be confounders with the knowledge and attitude of nurses towards diabetic foot ulcers and its care.

CONCLUSIONS: Nurses in this centre had poor knowledge towards diabetic foot ulcers and its care. None of the variable studied were correlated with the level know knowledge. Good or poor knowledge of nurses does not correspond equally to good or poor attitude towards diabetic foot ulcers care. More frequent formal training of diabetic foot care would be needed to ensure better knowledge.

Fulltext The significant association between polymicrobial diabetic foot infection and its severity and outcomes

Hitam SAS, Hassan SA, Maning N

Malays J Med Sci, 2019 Jan;26(1):107-114.
PMID: 30914898 MyJurnal DOI: 10.21315/mjms2019.26.1.10

Background: Foot infection is a major complication of diabetes mellitus (DM) and its agents are usually polymicrobial. This study aims to describe the agent and determine the association between polymicrobial infections and the severity of diabetic foot infections (DFI) and their outcomes.

Methods: This retrospective cohort study was conducted during one year and it involved 104 patients. Their records were reviewed and assessed. The causative agents and its sensitivity pattern were noted. The results were presented as descriptive statistic and analysed.

Results: A total of 133 microorganisms were isolated with 1.28 microorganisms per lesion. The microorganism isolated were 62% (n = 83) GN (Gram-negative) and 38% (n = 50) GP (Gram-positive). GN microorganisms include Pseudomonas spp (28%), Proteus spp (11%), Klebsiella spp (8%) and E. coli (4%). Staphylococcus aureus (54%) was predominant among GP, followed by Group B Streptococci (26%) and Enterococcus spp (6%). Thirty patients (28.8%) had polymicrobial infections. The association between the quantity of microorganisms and severity of DFI was significant. Among severe DFI cases, 77.8% with polymicrobial microorganisms underwent amputation compared to 33.3% with monomicrobial infection.

Conclusion: GN microorganisms were predominantly isolated from DFIs and remained sensitive to widely used agents. Polymicrobial infections were associated with DFI severity.
