In the present study we examined the effect of E. longifolia methanol extract (TA164) on the GSH levels of P. falciparum infected erythrocytes and uninfected erythrocytes. Our study on parasite growth shows the IC50 and IC75 values of TA164 to be 0.17 g/ml and 6 g/ml respectively while for BSO was 25.5 g/ml and 46.5 g/ml respectively. About 95% to 100% growth inhibition of P. falciparum infected erythrocyte was observed when treated with TA164 and BSO at 16 g/ml and 64 g/ml respectively. The study on GSH contents indicated that non-infected erythrocytes treated with 6 g/ml (IC75 values) of TA164 at 24 hours incubation showed less GSH content as compared to non-treated erythrocytes. A similar observation was seen on treated trophozoite infected erythrocyte (10% parasitemia) when treated with 6 g/ml at 3 hours incubation. Analysis of the GSH contents of parasite compartments treated with TA164 at the same concentration (6 g/ml) for 3 hours incubation indicated a reduction of GSH contents. At the same concentration, TA164 did not affect the GSH contents of enriched trophozoite infected erythrocytes (60-70% parasitemia). TA164 did affect the GSH content of non-infected erythrocyte at 24 hours (accept IC50 value) as well as the parasite compartments (trophozoite infected erythrocyte and parasite itself) but fails to affect the GSH content of enriched trophozoite infected erythrocyte.

We report a 21-year old female patient who presented with
an 18-month history of a swelling in the distal phalanx of
her right little finger. Although the history, clinical features
and MRI were suggestive of a benign tumour or a
tuberculous lesion, the histo-pathological examination of the
swelling was reported as a conventional osteosarcoma.
Osteosarcoma of the hand is very rare. This article highlights
the possibility of a seemingly benign lesion seen in a routine
clinic could well turn out to be malignant, and the need to
maintain a high index of suspicion

Eurycoma longifolia, locally known as 'Tongkat Ali' is a popular local medicinal plant that possess a lot of medicinal properties as claimed traditionally, especially in the treatment of malaria. The claims have been proven scientifically on isolated compounds from the plant. The present study is to investigate the anti malaria properties of Eurycoma longifolia standardized extract (root) (TA164) alone and in combination with artemisinin in vivo. Combination treatment of the standardized extract (TA164) with artemisinin suppressed P. yoelii infection in the experimental mice. The 4 day suppressive test showed that TA164 suppressed the parasitemia of P. yoelii-infected mice as dose dependent manner (10, 30 and 60 mg/kg BW) by oral and subcutaneous treatment. By oral administration, combination of TA164 at 10, 30 and 60 mg/kg BW each with artemisinin respectively showed a significant increase in the parasitemia suppression to 63, 67 and 80 percent as compared to artemisinin single treatment (31%). Using subcutaneous administration, at 10 mg/kg BW of TA164 in combination with 1.7 mg/kg BW of artemisinin gave a suppression of 80% of infection. This study showed that combination treatment of TA164 with artemisinin gives a promising potential anti malaria candidate using both oral and subcutaneous route, the later being the most potent.

In Malaysia, maggot debridement therapy (MDT) utilizes maggots of Lucilia
cuprina (Wiedemann) to debride necrotic tissue from wound surface, reduce bacterial infection
and therefore, enhance wound healing process. To evaluate the sterility of the sterile maggots
produced after sterilization process before delivering onto patient wounds. Sterility of sterile
maggots is crucial in ensuring the safe usage of MDT and patient’s health. Eggs of L. cuprina
collected from a laboratory colony were divided into treated group (sterilized) and control
group (non-sterilized). Treated group underwent sterilization while eggs from control group
were allowed to hatch without sterilization. Sodium hypochlorite and formaldehyde were the
main disinfectants used in this sterilization process. Scanning electron microscope (SEM)
was used to examine and ascertain the sterility of sterile maggots. SEM results showed that
all sterilized L. cuprina eggs and maggots achieved sterility and all were cleared from
bacterial contamination. In contrast, all non-sterilized eggs and maggots were found to be
colonized by microorganisms. Sterilization method employed to sterilize eggs and maggots
used in Malaysia MDT was proven successful and MDT is safe to be used as wound management
tools.

Malaria is a disease which is still endemic and has become a disastrous scourge because of the emergence of antimalarial drug resistant Plasmodium falciparum. A new approach in addressing this is in developing a combination drug. This study is to show the enhancement of antimalarial properties, when single compound, goniothalamin combine with standard drug, chloroquine. Based on 4 Day Test, percentage of parasite growth on treated infected mice were determined. Oral treatment with 1 mg/kg BW of chloroquine on experimental mice suppressed 70% and 76.7% of both Plasmodium yoelii and Plasmodium berghei, respectively. The infection of P. berghei in mice was inhibited less than 50% by goniothalamin individual treatment at all doses in this study. About 27.8% and 18.5% inhibition of infection were observed in P. yoelii infected mice treated with 30 mg/kg and 60 mg/kg of goniothalamin respectively and the suppression exceed more than 50% at higher doses (90 and 120 mg/kg). Combination of 1 mg/kg chloroquine with either 30 mg/kg or 60 mg/kg of goniothalamin decreased the parasitemia of P. yoelii infected mice more than 90% and prolong the survival up to 100% after treatment. Similar treatment to P. berghei infected mice only shows about 60% reduction of parasitemia. The study findings showed that antimalarial property of goniothalamin was enhanced by combination with chloroquine at lower dose of each drug.

Seven Malaysian medicinal plants were screened for their antiplasmodial activities in vitro. These plants were selected based on their traditional claims for treatment or to relieve fever. The plant extracts were obtained from Forest Research Institute Malaysia (FRIM). The antiplasmodial activities were carried out using the pLDH assay to Plasmodium falciparum D10 strain (sensitive strain) while the cytotoxic activities were carried out towards Madin- Darby bovine kidney (MDBK) cells using MTT assay. The concentration of extracts used for both screening assays were from the highest concentration 64 microg/ml, two fold dilution to the lowest concentration 0.03 microg/ml. Goniothalamus macrophyllus (stem extract) showed more than 60% growth inhibition while Goniothalamus scortechinii root and stem extract showed a 90% and more than 80% growth inhibition at the last concentration tested, 0.03 microg/ml. The G. scortechini (leaves extract) showed an IC50 (50% growth inhibition) at 8.53 microg/ml, Ardisia crispa (leaves extract) demonstrated an IC50 at 5.90 +/- 0.14 microg/ml while Croton argyratus (leaves extract) showed a percentage inhibition of more than 60% at the tested concentration. Blumea balsamifera root and stem showed an IC50 at 26.25 +/- 2.47 microg/ml and 7.75 +/- 0.35 microg/ ml respectively. Agathis borneensis (leaves extract) demonstrated a 50% growth inhibition at 11.00 +/- 1.41 microg/ml. The study gives preliminary scientific evidence of these plant extracts in line with their traditional claims.

The human genome contains many submicroscopic copy number variations which includes deletions, duplications and insertions. Although conventional karyotyping
remains an important diagnostic tool in evaluating a dysmorphic patient with mental retardation, molecular diagnostic technology such as array comparative genomic
hybridization (aCGH) has proven to be sensitive and reliable in detecting these submicroscopic anomalies. A 3 month-old infant with dysmorphic facies, microcephaly
and global developmental delay was referred for genetic evaluation. Preliminary karyotyping which was confounded by the quality of metaphase spread was normal;
however, aCGH detected a 30.6Mb deletion from 5p15.33-p13.3. This case illustrates the usefulness of aCGH as an adjunctive investigative tool for detecting chromosomal
imbalances.

Hypertension is one of the commonest health problems in Malaysia and its cases are on a rise. In conjunction with the above statement, it is predictable that the cost of healthcare services will further increase in the future. Therefore, cost study is necessary to estimate the health related economic burden of hypertension in Malaysia. A cross sectional study was carried out to quantify the direct treatment cost of hypertension. Three hundred and ninety one hypertensive patients’ data from Bandar Tasik Selatan Primary Medical Centre in year 2010 were collected and analysed. The direct treatment costs were calculated. The result showed that out of 391 hypertensive patients, 12.5% was diagnosed hypertensive without any co-morbidity, 25.3% with 1 co-morbidity dyslipidemia only; 4.3% with diabetes mellitus type 2 only; 0.5% with chronic kidney disease only and none with ischaemic heart disease. Patients with 2 co-morbidities (dyslipidemia and diabetes mellitus type 2) were 42.2%; with 3 co-morbidities (diabetes mellitus type 2, dyslipidemia and chronic kidney disease) was 4.3%. The mean cost of direct treatment of hypertension per visit/ year was RM289.42 ±196.71 with the breakdown costs for each component were medicines 72.2%, salary 14.6%, laboratory tests 5.0%, administration 4.4% and radiology tests 3.8%. Dyslipidemia is by far the commonest co-morbidity among hypertensive patients. Direct costs of treating hypertension are mostly dependent on present of co-morbidity and numbers of drugs used. Thus, the annual budget could be calculated precisely in the future especially for drugs.

Aims:
Preterm premature rupture of membrane (PPROM) is usually associated with maternal vaginal colonization of Group B Streptococci (GBS). However, there are reports on isolation of Acinetobacter baumannii in PPROM cases. In order to ascertain A. baumannii’s role in PPROM, we determine the colonization of A. baumannii and other common vaginal tract flora, i.e. GBS and Candida albicans, in women with PPROM, and compared them to those with normal labor at term (NLT). The transmissibility of the organisms to their babies was also investigated.
Methodology and results:
A total of 218 high vaginal swabs from 108 and 100 women with PPROM and NLT respectively were collected. The transmission of these organisms to their 215 babies was determined by swabbing the ears and axillae. These were cultured for isolation of A. baumannii, GBS and C. albicans. Results showed that mothers with PPROM were predominantly colonized with GBS (32.4%), followed by C. albicans (19.4%) and A. baumannii (7.4%), compared to 10.9%, 17.3% and 7.2% respectively, in women with NLT. Between 34 to 50% of the babies of mothers with PPROM acquired the organisms, with GBS being the most significantly (p=0.000) transferred compared to other organisms. Co-existence of A. baumannii with either GBS or C. albicans, or both, did not enhance the occurrence of PPROM.
Conclusion, significance and impact of study
Colonization of A. baumannii in vaginal tract of pregnant women does not increase the possibility of PPROM, as compared to GBS.

Some anecdotal reports suggest that maternal
colonisation with Acinetobacter baumannii during
pregnancy is associated with adverse maternal and neonatal
effects, including preterm premature rupture of membrane
(PPROM). The objective of this study was to compare the
maternal and neonatal effects of A. baumannii colonisation
in cases with PPROM and those with spontaneous onset of
labour at term.
