Benzathine penicillin G (BPG) is used as first-line treatment for most forms of syphilis and as secondary prophylaxis against rheumatic heart disease (RHD). Perceptions that poor quality of BPG is linked to reported adverse effects and therapeutic failure may impact syphilis and RHD control programs. Clinical networks and web-based advertising were used to obtain vials of BPG from a wide range of countries. The quality of BPG was assessed using a high performance liquid chromatography assay capable of detecting relevant impurities and degradation products. Tests for water content, presence of heavy metals and physical characteristics of BPG, including particle size analysis and optical microscopy, also were conducted. Thirty-five batches of BPG were sourced from 16 countries across 4 WHO regions. All batches passed the US Pharmacopeia requirements for BPG injection (content), with no evidence of breakdown products or other detected contaminants. Water content and heavy metal analysis (n = 11) indicated adherence to regulatory standards and Good Manufacturing Practice. Particle size analysis (n = 20) found two batches with aggregated particles (>400 µm) that were dispersed following sonication. Current batches of BPG were of satisfactory pharmaceutical quality but aggregated particles were found in a modest proportion of samples. Future studies should focus on the physical characteristics of BPG which may contribute to variations in plasma penicillin concentrations an observed needle blockages in clinical practice. Pharmacopeial monographs could be revised to include standards on particle size and crystal morphology of BPG.

Fulltext Yaws in the Western pacific region: a review of the literature

Capuano C, Ozaki M

PMID: 22235208 DOI: 10.1155/2011/642832

Until the middle of the 20th century, yaws was highly endemic and considered a serious public health problem in the Western Pacific Region (WPR), leading to intensive control efforts in the 1950s-1960s. Since then, little attention has been paid to its reemergence. Its current burden is unknown. This paper presents the results of an extensive literature review, focusing on yaws in the South Pacific. Available records suggest that the region remains largely free of yaws except for Papua New Guinea, Solomon Islands, and Vanuatu. Many clinical cases reported recently were described as "attenuated"; advanced stages are rare. A single intramuscular injection of benzathine penicillin is still effective in curing yaws. In the Pacific, yaws may be amenable to elimination if adequate resources are provided and political commitment revived. A mapping of yaws prevalence in PNG, Solomon, and Vanuatu is needed before comprehensive country-tailored strategies towards yaws elimination can be developed.

MyJurnal

Introduction: Trigona thoracica propolis is known to have antimicrobial properties, however its
antileptospiral properties and its synergistic effects with commonly prescribed antibiotics are scarcely
documented. This study aimed to evaluate the antileptospiral properties of Trigona thoracica against
pathogenic Leptospira species (spp.) and to study its synergistic effects with commonly prescribed
antibiotics. Materials and Methods: The tested Leptospira serovars were Australis, Bataviae, Canicola and
Javanica. Aqueous extract propolis (AEP) and ethanolic extracts propolis (EEP) were used. Broth dilution
methods were used to determine the Minimum Inhibitory Concentration (MIC), Minimum Bactericidal
Concentration (MBC) and the synergistic effects between the propolis and the tested antibiotics. The
synergistic effects was evaluated by using the fractional inhibitory concentration (FIC) index. Morphological
changes of the treated Leptospira were observed under a Scanning Electron Microscope (SEM). Results: The
AEP and EEP were found to have antileptospiral properties against the tested Leptospira spp. The synergy
result showed that only combination of AEP and penicillin G against serovar Australis has demonstrated
synergistic effect with the FIC index of 0.38. Morphological study using SEM showed significant structural
changes of the treated Leptospira spp. Conclusions: The result suggests that Trigona thoracica propolis could
potentially be used as either a complimentary or an alternative therapeutic agent against pathogenic
Leptospira spp.

Fulltext Quintuplex PCR to detect antibiotic resistance genes in Streptococcus pneumoniae

Navindra Kumari Palanisamy, Parasakthi Navaratnam, Shamala Devi Sekaran

Journal of Clinical and Health Sciences, 2016;1:22-28.

Introduction: Streptococcus pneumoniae is an important bacterial pathogen, causing respiratory infection. Penicillin resistance in S. pneumoniae is associated with alterations in the penicillin binding proteins, while resistance to macrolides is conferred either by the modification of the ribosomal target site or efflux mechanism. This study aimed to characterize S. pneumoniae and its antibiotic resistance genes using 2 sets of multiplex PCRs. Methods: A quintuplex and triplex PCR was used to characterize the pbp1A, ermB, gyrA, ply, and the mefE genes. Fifty-eight penicillin sensitive strains (PSSP), 36 penicillin intermediate strains (PISP) and 26 penicillin resistance strains (PRSP) were used. Results: Alteration in pbp1A was only observed in PISP and PRSP strains, while PCR amplification of the ermB or mefE was observed only in strains with reduced susceptibility to erythromycin. The assay was found to be sensitive as simulated blood cultures showed the lowest level of detection to be 10cfu. Conclusions: As predicted, the assay was able to differentiate penicillin susceptible from the non-susceptible strains based on the detection of the pbp1A gene, which correlated with the MIC value of the strains.

Fulltext Prevailing practice versus clinical guideline: the in-patient assessment and management of childhood bronchopneuonia in a Malaysian district hospital

International e-Journal of Science, Medicine & Education, 2008;2(2):9-16.
MyJurnal

Introduction: Pneumonia is the most common diagnosis made in hospitalised children. The Malaysian Clinical Practice Guidelines on pneumonia and respiratory tract infections provides a comprehensive guidance in the local context. We evaluated the documented assessment and management of children diagnosed with pneumonia admitted to the children’s ward, Hospital Batu Pahat against this guideline.
Methods: We performed a retrospective analysis of hospital case notes for children admitted from January to May 2004.
Results: Ninety six case notes were analysed. Most patients (84%) had at least four positive clinical features leading to the diagnosis of pneumonia. 92% met the guideline criteria for admission. Sp02 was performed for 58% on admission, and 58% with reading below 95% received supplemental oxygen. Throughout hospital stay, each patient had an average of four investigations (range: 1 – 12). Among 23 patients who had further investigations, justifications were only recorded in seven patients (30.4%), and changes in management resulted in 23%. The most common antibiotic prescribed was intravenous Penicillin (97 %). In 17 patients who met the guideline classification for severe pneumonia, none received the recommended antibiotic combination. The median time to fever resolution was 22 hours (range 2 – 268), and median hospital stay was 3 days (range 1 – 12).
Conclusions: Although the quality of clinical assessment and antibiotic choices were acceptable, there was a failure to critically evaluate patients according to disease severity and initiate corresponding investigations and managements. Future efforts need to be directed at promoting further guideline adherence and the exercise of critical judgment in patient evaluation.

Numerous prevalence studies and outbreaks of Vibrio parahaemolyticus infection have been extensively reported in shellfish and crustaceans. Information on the quantitative detection of V. parahaemolyticus in finfish species is limited. In this study, short mackerels (Rastrelliger brachysoma) obtained from different retail marketplaces were monitored with the presence of total and pathogenic strains of V. parahaemolyticus. Out of 130 short mackerel samples, 116 (89.2%) were detected with the presence of total V. parahaemolyticus and microbial loads of total V. parahaemolyticus ranging from <3 to >10(5) MPN/g. Prevalence of total V. parahaemolyticus was found highest in wet markets (95.2%) followed by minimarkets (89.1%) and hypermarkets (83.3%). Pathogenic V. parahaemolyticus strains (tdh+ and/or trh+) were detected in 16.2% (21 of 130) of short mackerel samples. The density of tdh+ V. parahaemolyticus strains were examined ranging from 3.6 to >10(5) MPN/g and microbial loads of V. parahaemolyticus strains positive for both tdh and trh were found ranging from 300 to 740 MPN/g. On the other hand, antibiotic susceptibility profiles of V. parahaemolyticus strains isolated from short mackerels were determined through disc diffusion method in this study. Assessment of antimicrobial susceptibility profile of V. parahaemolyticus revealed majority of the isolates were highly susceptible to ampicillin sulbactam, meropenem, ceftazidime, and imipenem, but resistant to penicillin G and ampicillin. Two isolates (2.99%) exhibited the highest multiple antibiotic resistance (MAR) index value of 0.41 which shown resistance to 7 antibiotics. Results of the present study demonstrated that the occurrence of pathogenic V. parahaemolyticus strains in short mackerels and multidrug resistance of V. parahaemolyticus isolates could be a potential public health concerns to the consumer. Furthermore, prevalence data attained from the current study can be further used to develop a microbial risk assessment model to estimate health risks associated with the consumption of short mackerels contaminated with pathogenic V. parahaemolyticus.

Sains Malaysiana, 2014;43:543-550.

This study was carried out to know the bacteria population density in the blood cockle (Anadara granosa) and green lipped mussel (Perna viridis), to analyse the bacteria resistance towards antibiotics and antimicrobial activity of isolates against selected pathogen. Samples of blood cockle and green lipped mussel were obtained from five areas in Kedah and Negeri Sembilan. Bacterial population densities in mussels and cockles were 3 x 102 - 8 x 108 cFulmL and 5 x 102 - 5 x 108 cFulmL, respectively. A total of 162 isolates were obtained, of which 131 isolates were from mussels and 31 isolates were from cockles. Vibrio sp. was the most dominant genus in both types of samples. Antibiotic testing of all isolates showed most were resistant to Penicillin (10 U) and most were sensitive to Ciprofloxacin (5 Jig). Most isolates (160/162) showed resistance to at least two antibiotics and 10 isolates were resistant to more than five antibiotics. Multiple antibiotic resistance indices (MAR) were calculated based on the antibiotic resistance results. Most isolates had a MAR index value of 02 which indicated the isolates were not contaminated with antibiotic residues. The highest index value was 0 .7 . Fifteen out of 39 isolates which produced beta-lactamase enzyme were tested for antimicrobial activity against selected pathogen. Results indicated that antimicrobial activity were varies among the isolates. Isolate smii-Ip produced antimicrobial activity against six out of the nine tested pathogen and none of the isolates active against Pseudomonas mirabilis.

Fulltext Pneumococcal serotype distribution and antibiotic susceptibility in Malaysia: A four-year study (2014-2017) on invasive paediatric isolates

Arushothy R, Ahmad N, Amran F, Hashim R, Samsudin N, Azih CRC

Int J Infect Dis, 2019 Mar;80:129-133.
PMID: 30572022 DOI: 10.1016/j.ijid.2018.12.009

OBJECTIVE: This study was performed to analyze the serotype distribution of Streptococcus pneumoniae causing invasive pneumococcal disease (IPD) in children aged 5 years and under in Malaysia and to assess the antimicrobial resistance.
METHODS: From 2014 to 2017, a total of 245 invasive S. pneumoniae isolates from children ≤5 years of age were received from hospitals all around Malaysia. All isolates were identified and subjected to serotyping and antimicrobial susceptibility testing.
RESULTS: Of the 245 isolates, 117 (48.0%) were from children aged <1year, 46 (19.05%) were from children aged 1-2 years, and 82 (33.0%) were from children aged 2-5 years. The most common serotypes were 14 (26.9%), 6B (19.6%), 19A (11.8%), 6A (10.6%), and 19F (6.9%) and vaccine coverage was 88.2% for PCV13, 64.1% for PCV10, and 63.3% for PCV7. Resistance to penicillin was 0.2% for non-meningitis cases and 22.2% for meningitis cases; erythromycin resistance was reported in 42.9%, co-trimoxazole in 35.9%, and tetracycline in 42.9%.
CONCLUSIONS: Serotypes 14, 6B, 19A, 6A, and 19F were the most common serotypes isolated from children with IPD in Malaysia during this pre-vaccination era. The lack of reports on the serotype distribution has limited action for the implementation of PCV in the national immunization programme (NIP). The information from this study may benefit future policies for the introduction of PCV in the Malaysian NIP and ultimately may reduce the morbidity and mortality among children in Malaysia.

Fulltext Invasive Pneumococcal Pneumonia with Massive Empyema: a case report

Tin Nwe Latt

Journal of Clinical and Health Sciences, 2016;1:41-47.

Although the use of appropriate antibiotics has significantly improved the outcome of pneumonia, severe complications are still encountered. We report here of a case with invasive pneumococcal pneumonia with massive empyema. A 2-year-4-month old girl presented with fever for 8 days and intermittent cough for 2 weeks. On examination, reduced air entry with dullness on percussion was noted on the left lung. Chest ultrasound revealed moderate to gross pleural effusion with septations, for which left thoraco-centesis with insertion of pigtail tube was performed. Streptococcus pneumoniae was detected via polymerase chain reaction (PCR) test in the pleural fluid. Intravenous (IV) benzylpenicillin and ceftriaxone were given together with one course (5 days) of intrapleural urokinase to breakdown the septations. Timely and appropriate management of pneumonia including the use of thrombolytic agent is vital to ensure optimal outcome and reduce the need of invasive procedures in cases with massive empyema. Public awareness of pneumococcal vaccination is also essential as a part of preventive measures.

Introduction Ocular syphilis is a sight-threatening condition. It can occur at any stage of syphilis infection, which present either with acute inflammation during the primary, secondary, and early latent stages or with chronic inflammation during tertiary infection, affecting virtually every ocular structure. This study was to report on the clinical presentation of ocular syphilis that presented to eye clinic Hospital Universiti Sains Malaysia. Methodology This was a retrospective study where medical records of ocular syphilis patients who attended eye clinic in Hospital Universiti Sains Malaysia from January 2013 to June 2017 were reviewed. Results A total of 10 patients (13 eyes) with ocular syphilis were identified out of 106 cases that presented with ocular inflammation. The mean age of presentation was 69.8 ± 6.4 years and seven of them (70%) were female. All patients were Malay and human immunodeficiency virus (HIV) was negative. The ocular manifestations included panuveitis (four eyes, 30.8%), anterior uveitis (two eyes, 15.4%), posterior uveitis (seven eyes, 53.8%) and optic neuritis (two eyes, 15.4%). Seven (53.8%) eyes presented with visual acuity of worse than 6/60, five (38.5%) eyes had visual acuity between 6/15 to 6/60, and one (7.7%) eye had visual acuity of 6/12 or better. Nine patients received an intravenous benzylpenicillin regime and one patient received an intramuscular penicillin injection. Out of 13 eyes affected, 11 (84.6%) eyes had improved visual acuity of at least one Snellen line after treatment. Visual acuity of 6/12 or better increased to four (30.8%) eyes. Conclusions Posterior uveitis was the commonest presentation of ocular syphilis in HIV-negative patients. Early detection and treatment of ocular syphilis can result in resolution of inflammation and improvement of vision.

This study aimed to investigate the prevalence and antibiogram of Vibrio parahaemolyticus in processed bivalve molluscs in Kuala Terengganu. A total of 80 seafood samples, namely mussels (n=20), carpet clams (n=20), cockles (n=20) and scallops (n=20), were subjected to PCR and conventional plating method for the detection of V. parahaemolyticus. V. parahaemolyticus was found in green mussels (55%), carpet clam (80%), cockles (40%) and scallops (55%). Fifty-five V. parahaemolyticus isolates were subjected to 9 types antibiotic sensitivity test using discs diffusion method. All isolates were susceptible to Tetracycline and Gentamycin. Isolates showed high resistance towards Vancomycin (52.73%), Penicillin (45.45%) and Amplicillin (32.73%). Resistance towards Amikacin, Ciprofloxacin and Norfloxacin were found to be 1.82%. It can be concluded that local bivalve molluscs were contaminated with V. parahaemolyticus and isolates showed resistance towards certain antibiotics. Therefore, consumption of raw or semi-cooked bivalve molluscs is not advisable.

Streptococcus pneumoniae is an important cause of community acquired infections, particularly pneumonia, acute otitis media, sinusitis and exacerbations of chronic bronchitis. Together with Haemophilus influenzae, it is an important cause of childhood meningitis. It is also a major cause of bacterial meningitis among adults. The emergence of Streptococcus pneumoniae resistant to penicillin and other antibiotics in recent years has complicated the management of pneumococcal infections world-wide'. In some areas, penicillin resistant strains have become the predominant pneumococcal isolates2. Multiply resistant strains and those resistant to second and third generation cephalosporins are also increasingly reported'. Treatment of meningitis and acute otitis media caused by such strains is particularly problematic. (Copied from article).

Clostridium difficile infection (CDI) causes mild to severe diarrhoea and pseudomembranous colitis in patients who had prior antibiotic exposure. Despite CDI being prevalent worldwide, its epidemiological data is scanty in Malaysia. This study aimed to determine the prevalence and incidence of CDI at Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Stool specimens from 147-suspected CDI patients were obtained from 1 November 2011 until 31 October 2012. The presence of C. difficile toxin A and/or B were detected using a commercial immunochromatographic kit (Wampole™ Tox A/B Quik Chek). Surveillance data was collected from patients’ medical records to establish the demographic and clinical characteristics. The overall prevalence and incidence of CDI in UKMMC was 6.1% and 5.2 cases per 10 000 patient-days, respectively. Among nine CDI patients, 77.8% were males and 55.6% were Chinese. CDI was most common in medical wards (88.9%). The median age was 60 years and the median length of hospital stay was 13 days. Majority (88.9%) of CDI patients received antibiotics eight weeks prior to CDI. Penicillin-beta-lactamase inhibitors were the most common antecedent antibiotics. Five (55.6%) CDI patients received acid suppressant medications. The in-hospital mortality rate was 22.2%. In conclusion, the prevalence and incidence of CDI at UKMMC is relatively low and occurs sporadically.

The aim of this study was to isolate stem cells from dental pulp of primary molars and incisors to be used as possible source for tissue engineering. Human primary molars and incisors were collected from subjects aged 4-7 year-old under standardized procedures. Within 24 hours, the tooth was cut at the cemento-enamel junction using hard tissue material cutter. The dental pulp tissue was extracted, digested and then cultured in Alpha Modified Eagles's Medium (α-MEM) supplemented with 20% FCS, 100 mM L-ascorbic acid 2-phosphate, 200 mM L-glutamine and 5000 units/ml Penicillin/Streptomycin. The cells were observed daily under the microscope until confluence. Children's tooth pulp- derived progenitor cells were found positive for stem cell markers CD105 and CD166, which are consistent with the finding for mesenchymal stem cells (MSCs) from bone marrow.

Introduction and Objective: Pneumococcal disease is a leading cause of morbidity and mortality worldwide. There were limited publications on invasive pneumococcal infection (IPD) in Malaysia. The aim of this study is to describe restrospectively cases of IPD in hospitalised children of less than 12 years old and highlighting the unusual cases.

Methodology: A retrospective review of children with IPD from March 2002 to November 2005 at a tertiary paediatric hospital. IPD cases were defined as isolates of Streptococcus pneumoniae from a normally sterile body fluid site.

Results: Twenty-four patients were identified with a male preponderance. Two-thirds of patients were below 1-year-old; with three cases presenting in the premature newborn. Thirty-seven percent of cases had underlying conditions. Sepsis and pneumonia were the commonest manifestation, followed by meningitis. The unusual manifestations were in a form of postinfectious glomerulonephritis and overwhelming purpura fulminans. There were two mortalities; both infants had meningitis. Antibiotic susceptibility pattern showed that more than half of the isolates were sensitive towards penicillin and erythromycin. Penicillin resistance was found in 6 (25%) isolates. Conclusion: IPD results in significant morbidity and mortality, especially in young children below 2 years of age and justifies further evaluation of preventive strategies including the implementation of pneumococcal vaccine in the national immunisation programme.

Ninety one leaf samples of Josapine pineapple cultivar (Kelantan, n=8; Pahang, n=20; Perak, n=11; Sabah, n=15; Johor, n=37) showing symptoms of heart rot disease were collected to determine the incidence of Erwinia chrysanthemi. Sixteen strains of E. chrysanthemi were isolated from 13 leaf samples from Pahang (n=4), Sabah (n=2) and Johor (n=7). All of the E. chrysanthemi strains displayed resistance to bacitracin with two strains showing resistance to sulfamethoxazole. None of the E. chrysanthemi strains were resistant toward ampicillin, carbenicillin, cephalothin, ceftriaxone, cefuroxime, gentamicin, kanamycin, nalidixic acid, penicillin G, streptomycin and tetracycline. All of the E. chrysanthemi strains were plasmidless. The dendrogram generated from the ERIC-PCR fingerprinting showed that the E. chrysanthemi strains formed 4 clusters and 7 single isolates at 80% similarity level. The restriction fragment length polymorphism (RFLP) analysis for 16 strains of E. chrysanthemi with HinfI and HaeIII endonuclease, 2 and 4 restriction profiles were obtained, respectively. The combinations of the four techniques were able to differentiate the 16 E. chrysanthemi strains into 14 genome types, suggesting a wide diversity of strains examined. ERICPCR fingerprinting method is found to be more discriminating and useful for the determination of the E. chrysanthemi strains relatedness.

Med J Malaysia, 2018 10;73(5):323-325.
PMID: 30350813 MyJurnal

Acute Rheumatic fever (ARF) is commonly associated with ECG abnormalities particularly atrioventricular block. However, third degree atrioventricular block or complete heart block is a rare manifestation. Most cases occurred in children. We reported a 25 year old man who developed complete heart block during an acute episode of ARF. He presented to hospital with five days history of fever, malaise and migrating arthralgia, followed by pleuritic chest pain. One day after admission his electrocardiogram (ECG) revealed complete heart block. Transthoracic echocardiography showed good left ventricular function with thickened, mild mitral regurgitation with minimal pericardial effusion. ASOT titer was positive with elevated white blood count and acute phase reactant. A temporary pacemaker was inserted in view of symptomatic bradycardia. The complete heart block resolved after medical therapy. He was successfully treated with penicillin, steroid and aspirin. He was discharged well with oral penicillin. The rarity of this presentation is highlighted.
