    The present study was carried out to establish the antinociceptive and anti-inflammatory properties of Dicranopteris linearis leaves chloroform extract in experimental animals. The antinociceptive activity was measured using the abdominal constriction, formalin and hot plate tests, while the anti-inflammatory activity was measured using the carrageenan-induced paw edema. The extract, obtained after 72 h soaking of the air-dried leaves in chloroform followed by evaporation under vacuo (40 degrees C) to dryness, was dissolved in dimethyl sulfoxide to the doses of 20, 100 and 200 mg/kg and administered subcutaneously 30 min prior to subjection to the above mentioned assays. The extract, at all doses used, was found to exhibit significant (p<0.05) antinociceptive activity in a dose-dependent manner. However, the significant (p<0.05) anti-inflammatory activity observed occur in a dose-independent manner. As a conclusion, the chloroform extract of D. linearis possesses antinociceptive and anti-inflammatory activity and thus justify its traditional uses by the Malays to treat various ailments.

    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.

    Abstract. Salmonella enterica serovar Paratyphi B is known to cause either paratyphoid fever or gastroenteritis. Differentiation of Salmonella ser. Paratyphi B into biotype Java (d-tartrate fermenting, dT+) and biotype Paratyphi B (d-tartrate non-fermenting, dT) is important for Salmonella epidemiology. This study applied a PCR approach to differentiate the two biotypes to augment the conventional biochemical method and to determine the antibiograms and genomic diversity of Malaysian S. Paratyphi B. Among 100 strains tested (clinical, 86; non-humans, 14), only two clinical strains were confirmed as biotype Paratyphi B as indicated by both lead acetate test and PCR. Antibiotic resistance rates were as follows: streptomycin 18%, sulphonamides 13%, ampicillin 10%, chloramphenicol 4%, tetracycline 3%, cefotaxime 2%, cefpodoxime 2%, ceftazidime 2%, gentamicin 1% and trimethoprim 1%. None showed resistance towards amoxicillin-clavulanic acid, ceftiofur, ciprofloxacin, nalidixic acid and trimethoprim-sulphamethoxazole. Seven strains showed multidrug resistance towards 3 or more classes of antimicrobial agents. REP-PCR and PFGE generated 32 and 76 different profiles, respectively. PFGE (D = 0.99) was more discriminative than REP-PCR (D = 0.93) and antimicrobial susceptibility test (D = 0.48) in subtyping the strains. Strains isolated 18 years apart (1982 - 2008) from different localities in Malaysia were clonally related as demonstrated by REP-PCR and PFGE, indicating that these strains were stable and widely distributed. In some clusters, strains isolated from different sources (clinical, food and animal) were grouped together. Thus, biotype Java was the most common biotype of Salmonella ser. Paratyphi B in Malaysia. The PCR approach is highly recommended due to its simplicity, specificity and ease of operation. The level of antimicrobial resistance among Salmonella ser. Paratyphi B remained relatively low in Malaysia but the emergence of resistance to cephalosporins is a cause for concern.

    Pharmacological and biochemical studies on the Ammi majus seeds L. (family Umbelliferae) grown in Egypt are limited. Furocoumarins are the major constituents in the plant seeds. In the present study, the evaluation of the antihyperlipidemic, anti-inflammatory, analgesic, and antipyretic activities on albino rats and mice was done. After 2 months of administration, both the doses (50 and 100 mg/kg body weight [bwt], respectively) of the alcoholic extract of the A. majus seed result in a significant decrease in the concentrations of cholesterol, triglycerides, and low-density lipoprotein and increase in the concentration of high-density lipoprotein. The extract was found to inhibit the rat paw edema at both the doses, which means that it exerts a significant anti-inflammatory activity compared with control-untreated groups at the intervals of 30 and 60 minutes posttreatment. The antipyretic effect of the extract was quite obvious; it showed that 100 mg/kg bwt was more potent in lowering body temperature starting after 1 hour of treatment than the lower dose (50 mg/kg bwt). It is worth to mention that the A. majus extract with its coumarin contents as well as the tested biological activities of the plant was investigated for the first time in the current study. In conclusion, ethanolic extract of the A. majus seeds had antihyperlipidemic, anti-inflammatory, analgesic, and antipyretic activities that are dose dependant.

    BACKGROUND: Typhoid fever causes global morbidity and mortality and is a significant health burden, particularly in low- and middle-income countries. The direct fecal-oral route is the main transmission mode, but indirect environmental transmission could occur, particularly in urban settings. This study aimed to investigate the burden and trend of typhoid fever, reporting the coverage system between government and private practice and pattern of multidrug-resistant (MDR) typhoid cases in the urban Klang Valley area from 2011 to 2015.

    METHODS: The data from a cross-sectional study retrieved from the e-Notifikasi System, a national reporting system for communicable diseases provided by the Disease Control Division, Ministry of Health Malaysia and secondary data of all the typhoid cases were obtained from the public and private hospitals and laboratories in Klang Valley. Descriptive analysis was performed to examine the sociodemographic characteristics, spatial mapping was conducted to examine trends, and the crude incidence rates of confirmed typhoid cases and percentage of reporting coverage were calculated. Significant differences between MDR and non-MDR Salmonella typhi were determined in the patient's sociodemographic characteristics, which were analyzed using χ2 test. P values fever cases were reported in Klang Valley; however, only 265 cases were confirmed by culture tests. The crude incidence rates of confirmed cases were between 0.5 to 0.7 but peaked at 1.42 per 100,000 population in 2015. Most typhoid fever cases were observed among men (55.6%), individuals aged 21 to 30 years (27.6%), Malaysians (86.3%) and individuals of Malay ethnicity (52.1%). The reporting coverage of confirmed cases was 78.9% and non-reporting coverage of unconfirmed typhoid cases was 79.5%. The predictive value positive (PVP) was 89.3, and 7.5% were detected as MDR Salmonella typhi. Statistical significance was found in gender, citizenship and ethnicity regarding MDR Salmonella typhi (p = 0.004, p = 0.008 and p = 0.034, respectively).

    CONCLUSIONS: The local transmission of typhoid is still prevalent in the Klang Valley despite rapid urbanization and development in recent years. These findings are essential for policy makers to plan and implement focused and effective preventative activities to curb typhoid infection in urban areas.

    The anti-pyretic activity of a standardized methanol/water (50/50) extract of Orthosiphon stamineus Benth. (SEOS) was investigated for its effect on normal body temperature and yeast-induced pyrexia in Sprague Dawley (SD) rats. The SEOS showed no effect on normal body temperature. Doses of 500 and 1000 mg/kg body weight of SEOS significantly reduced the yeast-induced elevation in body temperature. This effect persisted up to 4 h following the administration of the extract. The anti-pyretic effect of SEOS was comparable with that of paracetamol (acetaminophen in U.S) (150 mg/kg p.o.), a standard anti-pyretic agent. HPLC study revealed that rosmarinic acid, sinensetin, eupatorin and tetramethoxyflavone were present in SEOS in the amounts of 7.58%, 0.2%, 0.34% and 0.24% respectively. The LD(50) of the extract in rats was higher than 5000 mg/kg body weight. Therefore, the present study ascertained that SEOS possesses a significant anti-pyretic activity.

    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.

    Despite concerns about adverse effects, chloramphenicol (CMC) continues to be used in certain situations and, due to its low therapeutic index and variable pharmacokinetics, therapeutic drug monitoring (TDM) is often recommended. At our centre, CMC finds applications in typhoid and meningitis and TDM is routinely performed. Elsewhere in Malaysia, however, CMC is used without TDM. We therefore decided to evaluate our TDM for CMC in relation to its roles in CMC therapy in children, who constitute most of our patients. Our objective was also to develop strategies to improve our TDM for CMC use. Data were collected from 168 children given CMC for various indications and monitored by the TDM service. Plasma CMC was determined by HPLC and used to adjust doses to maintain concentrations within a range of 10-25 micrograms/ml. Outcomes measured included daily temperatures and haematological indices. Daily doses and plasma CMC varied greatly. Doses averaged 40.5 mg/kg for neonates and 75.5 for older children. Average peak concentrations were therapeutic in 60% and trough in 42%. Average duration of fever was 6.3 days and it was unaffected by plasma CMC. Typhoid was eradicated in 97% but nine children with other diagnoses died. Side-effects were confined to mild reversible haematological abnormalities which developed in 11% of children at plasma concentrations which tended to be high. We conclude that CMC remains useful in children with typhoid. Its use for other indications, however, should be reviewed. Routine TDM for CMC is probably not warranted, at least until a clearer role is defined by well designed prospective studies.

    A retrospective study of 137 patients with blood culture-positive typhoid fever admitted to the paediatric unit of the Hospital Universiti Sains Malaysia was carried out to study epidemiological, clinical, laboratory and treatment aspects of typhoid fever in Kelantanese children in hospital. The male:female ratio was 1:1.1. School-children were the most affected. Cases were seen throughout the year. The five most frequently presenting features were fever, hepatomegaly, diarrhoea, vomiting and cough. Rose spots were seen in only two patients. Complications included gastritis, bronchitis, ileus, psychosis, encephalopathy, gastro-intestinal bleeding and myocarditis. Relative bradycardia was not seen. Blood and stool cultures were positive in the 1st, 2nd and 3rd weeks of illness. There was no significant difference between percentages of elevated O and H titres, whether done during or after the 1st week of illness. A four-fold rise in (O) titres occurred in 50% of cases tested. We would miss 50% of typhoid fever cases if a titre (O) equal to more than 1/160 were relied upon for diagnosis. Altogether, 46% of patients had leucopenia. Chloramphenicol was the most commonly used antibiotic. There were two deaths.

    The present study was carried out to evaluate the antinociceptive, anti-inflammatory and antipyretic effects of the aqueous extract of Solanum nigrum leaves using various animal models. The extract, at concentrations of 10, 50 and 100%, was prepared by soaking (1:20; w/v) air-dried powdered leaves (20 g) in distilled water (dH2O) for 72 h. The extract solutions were administered subcutaneously in mice/rats 30 min prior to the tests. The extract exhibited significant (P < 0.05) antinociceptive activity when assessed using the abdominal constriction, hot plate and formalin tests. The extract also produced significant (P < 0.05) anti-inflammatory and antipyretic activities when assessed using the carrageenan-induced paw edema and brewer's yeast-induced pyrexia tests, respectively. Overall, these activities occurred in a concentration-dependent manner, except for the 50% concentration of the extract, which was not effective in the abdominal constriction test. In conclusion, the present study demonstrated that S. nigrum leaves possessed antinociceptive, anti-inflammatory and antipyretic effects and thus supported traditional claims of its medicinal uses.

    Currently, there are no licensed vaccines or therapies available against chikungunya virus (CHIKV), and these were subjects discussed during a CHIKV meeting recently organized in Langkawi, Malaysia. In this review, we chart the approaches taken in both areas. Because of a sharp increase in new data in these fields, the present paper is complementary to previous reviews by Weaver et al. in 2012 and Kaur and Chu in 2013 . The most promising antivirals so far discovered are reviewed, with a special focus on the virus-encoded replication proteins as potential targets. Within the vaccines in development, our review emphasizes the various strategies in parallel development that are unique in the vaccine field against a single disease.

    Hemolysin E (HlyE) is an immunogenic novel pore-forming toxin involved in the pathogenesis of typhoid fever. Thus, mapping of B-cell epitopes of Salmonella enterica serovar Typhi (S. Typhi) is critical to identify key immunogenic regions of HlyE. A random 20-mer peptide library was used for biopanning with enriched anti-HlyE polyclonal antibodies from typhoid patient sera. Bioinformatic tools were used to refine, analyze and map the enriched peptide sequences against the protein to identify the epitopes. The analysis identified both linear and conformational epitopes on the HlyE protein. The predicted linear GAAAGIVAG and conformational epitope PYSQESVLSADSQNQK were further validated against the pooled sera. The identified epitopes were then used to isolate epitope specific monoclonal antibodies by antibody phage display. Monoclonal scFv antibodies were enriched for both linear and conformational epitopes. Molecular docking was performed to elucidate the antigen-antibody interaction of the monoclonal antibodies against the epitopes on the HlyE monomer and oligomer structure. An in-depth view of the mechanistic and positional characteristics of the antibodies and epitope for HlyE was successfully accomplished by a combination of phage display and bioinformatic analysis. The predicted function and structure of the antibodies highlights the possibility of utilizing the antibodies as neutralizing agents for typhoid fever.

    We prospectively studied the type, frequency and outcome of infections in 513 patients with 762 consecutive episodes of febrile neutropenia (FN) over a five-year period between 1995 and 1999 in a single paediatric oncology unit. The findings were then compared with a similar study carried out in our unit between 1990 and 1994. The types of bacterial isolates and sensitivity patterns were also studied to identify trends and to gauge the suitability of antibiotics chosen for empirical therapy. Bacteraemia was documented in 35.4% of FN episodes, although 70% of patients did not have an obvious site of sepsis. The majority of isolates (61.9%) were gram-negative bacteria, a consistent finding throughout the study period. Resistance to ceftazidime, amikacin and imipenem among gram-negative bacteria was 26.3%, 21.2% and 0.7%, respectively. Methicillin resistance among gram-positive bacteria was 26.3%, while no vancomycin-resistant bacteria were encountered. There were 36 sepsis-related deaths. Factors associated with a fatal outome were prolonged capillary refill time, hypotension, fever above 39 degrees C and pneumonia. Rapid neutrophil recovery was associated with a good prognosis. A change to our current choice of empirical antibiotics for FN, comprising ceftazidime/ceftriaxone and amikacin appears necessary because of the relatively high resistance rates found.

    To find the incidence, markers and nature of complications of typhoid fever, we studied 102 children with cultures positive for Salmonella typhi in a cross-sectional study, prospectively, over a period of almost 5 years. All isolates were sensitive to commonly used antibiotics. One third of these children developed complications which included: anicteric hepatitis, bone marrow suppression, paralytic ileus, myocarditis, psychosis, cholecystitis, osteomyelitis, peritonitis, pneumonia, haemolysis, and syndrome of inappropriate release of antidiuretic hormone (SIADH). Twelve children developed multiple complications. If hepatitis is excluded from the complications, the rate of complications in bacteriologically confirmed cases of typhoid fever drops to 11 per cent. These complications were not related to: the age or sex of patients, duration of illness before admission, use of antibiotics before admission, nutritional status, level of 'O' or 'H' titre, presence of IgM or IgG antibodies, or treatment with chloramphenicol or ampicillin. Children with splenomegaly, thrombocytopenia or leukopenia were more likely to develop complications.
