    The NADI program (pulse in Malay) was initially launched as a pilot project in 1980 in Kuala Lumpur, Malaysia. It utilized an integrated approach involving both the government and the private sectors. By sharing resources and expertise, and by working together, the government and the people can achieve national development faster and with better results. The agencies work through a multi-level supportive structure, at the head of which is the steering committee. The NADI teams at the field level are the focal points of services from the various agencies. Members of NADI teams also work with urban poor families as well as health groups, parents-teachers associations, and other similar groups. The policy and planning functions are carried out by the steering committee, the 5 area action committees and the community action committees, while the implementation function is carried out by the area program managers and NADI teams. The chairman of each area action committee is the head of the branch office of city hall. Using intestinal parasite control as the entry point, the NADI Integrated Family Development Program has greatly helped in expanding inter-agency cooperation and exchange of experiences by a coordinated, effective and efficient resource-mobilization. The program was later expanded to other parts of the country including the industrial and estate sectors. Services provided by NADI include: comprehensive health services to promote maternal and child health; adequate water supply, proper waste disposal, construction of latrines and providing electricity; and initiating community and family development such as community education, preschool education, vocational training, family counseling and building special facilities for recreational and educational purposes.

    Damage to the lower ureters during pelvic surgery is a serious and well-recognised complication. This iatrogenic injury, when undetected intra-operatively, continues to give rise to significant patient morbidity. In 1987, this Department was referred 18 cases of iatrogenic ureteric injuries. 16 patients were from gynaecologic surgery and 2 patients were from general surgery. Only 4 cases (24%) were detected and referred intra-operatively. 13 patients presented post-operatively with various symptoms viz., anuria, loin pain and urinary leak per vagina. Good recovery of urinary function was achieved in all cases after urological intervention, usually by ureteric re-implantation.

    Fracture of the penis is not an uncommon urological emergency. Six patients with this injury, treated at the Institute of Urology, General Hospital, Kuala Lumpur, since 1988, were reviewed. Their ages ranged from 21 to 30 years old (mean 25). Four cases were self-inflicted by abnormal bending and 2 cases occurred during sexual intercourse. A sudden "cracking sound", violent pain, rapid flaccidity and deformity of the penis were documented. Duration of injury at presentation ranged from 12 to 90 hours (mean 35 hours). Primary repair of the tunica albuginea with absorbable suture was performed in all cases. The results of surgery was excellent, with restoration of normal function in 4 patients (2 patients defaulted follow-up). We advocate immediate surgical repair for this injury.

    A modified nested polymerase chain reaction (PCR) method for detection of Plasmodium falciparum, P. vivax and P. malariae was combined with a simple blood collection and deoxyribonucleic acid (DNA) extraction method and evaluated in Malaysia. Finger-prick blood samples from 46 hospital patients and 120 individuals living in malaria endemic areas were spotted on filter papers and dried. The simple Chelex method was used to prepare DNA templates for the nested PCR assay. Higher malaria prevalence rates for both clinical (78.2%) and field samples (30.8%) were obtained with the nested PCR method than by microscopy (76.1% and 27.5%, respectively). Nested PCR was more sensitive than microscopy in detecting mixed P. falciparum and P. vivax infections, detected 5 more malaria samples than microscopy on the first round of microscopical examination, and detected malaria in 3 microscopically negative samples. Nested PCR failed to detect parasite DNA in 2 microscopically positive samples, an overall sensitivity of 97.4% compared to microscopy. The nested PCR method, when coupled with simple dried blood spot sampling, is a useful tool for collecting accurate malaria epidemiological data, particularly in remote regions of the world.

    Malaria remains a disease of underdeveloped and remote regions of the world. The application of polymerase chain reaction (PCR) technology to malaria epidemiology has the potential for increasing our knowledge and understanding of this disease. In order to study malaria in all geographical locations it is important that specimen collection and DNA extraction for PCR be kept simple. Here we report a method for extracting DNA from dried blood spots on filter paper which is capable of detecting one Plasmodium falciparum and two Plasmodium vivax parasites/microliter of whole blood by nested PCR without compromising the simplicity of specimen collection or DNA extraction.

    OBJECTIVE: A single cross-over, comparative pharmacokinetic study of oral and rectal formulations of 200 mg artesunic acid in 12 healthy Malaysian volunteers is reported.

    METHODS: Plasma concentrations of artesunic acid and dihydroartemisinin were determined simultaneously by HPLC with electrochemical detection. The test drug was well tolerated and no undesirable adverse effects were observed.

    RESULTS: Comparison of pharmacokinetic parameters of artesunic acid after oral and rectal administration showed statistically significant differences in t(max) and AUC, with no changes for Cmax and t1/2. As for dihydroartemisinin, differences were observed for t(max) and Cmax but not for AUC.

    CONCLUSION: There appear to be pharmacokinetic differences between oral and rectal modes of administration. The significance of these findings should be explored in malaria patients before appropriate therapeutic regimens are devised.

    A nested polymerase chain reaction (PCR) assay that uses Plasmodium genus-specific primers for the initial PCR (nest 1) amplification and either genus- or species-specific primers for the nest 2 amplifications was tested on laboratory and field samples. With in vitro cultured Plasmodium falciparum-infected blood samples, it was capable of detecting six parasites/microl of blood using DNA prepared from 25-microl blood spots on filter paper. The assay was evaluated on fingerprick blood samples collected on filter paper from 129 individuals living in a malaria-endemic area in Malaysia. Malaria prevalence by genus-specific nested PCR was 35.6% (46 of 129) compared with 28.7% (37 of 129) by microscopy. The nested PCR detected seven more malaria samples than microscopy in the first round of microscopic examination, malaria in three microscopically negative samples, six double infections identified as single infections by microscopy and one triple infection identified as a double infection by microscopy. The nested PCR assay described is a sensitive technique for collecting accurate malaria epidemiologic data. When coupled with simple blood spot sampling, it is particularly useful for screening communities in remote regions of the world.

    In this prospective study, we examined stool specimens from children with cancer receiving chemotherapy who were admitted for fever to the Universiti Sains Malaysia Hospital in Kota Baru, Kelantan. Stool specimens were examined for ova and cysts of parasites. Over a period of 15 months, there were 129 febrile episodes in 50 children with cancer and, in all, 237 stool specimens were examined. Sixty-six per cent of febrile episodes were associated with neutropenia and 9 per cent were associated with diarrhoea. Stool parasites were found in 42 per cent of children. The most common were helminths, followed by protozoa. Trichuris trichiura was the most common parasite (24 per cent), followed by Ascaris lumbricoides (22 per cent). Hookworm was found in 2 per cent. Giardia lamblia was found in 6 per cent of children, Blastocystis hominis in 4 per cent, and Cryptosporidium parvum in 2 per cent.

    The effects of medium strategy, number of impellers, aeration mode, and mode of operation on Morinda elliptica cell suspension cultures in a stirred-tank bioreactor are described. A lower number of impellers and continuous aeration contributed toward high cell growth rate, whereas a higher number of impellers reduced cell growth rate, although not anthraquinone yield. The semicontinuous mode could indirectly imitate the larger scale version of production medium strategy and improved anthraquinone production even with 0. 012% (v/v) antifoam addition. Production medium promoted both growth (maximum dry cell weight of 24.6 g/L) and anthraquinone formation (maximum content of 19.5 mg/g of dry cell weight), without any necessity for antifoam addition. Cultures in production medium or with higher growth rate and anthraquinone production were less acidic than cultures in growth medium or with lower growth rate and anthraquinone production. Using the best operating variables, growth of M. elliptica cells (24.6 g/L) and anthraquinone yield (0.25 g/L) were 45% and 140%, respectively, lower than those using a shake flask culture after 12 days of cultivation.

    Presentation of breast cancer during pregnancy is a rare situation and one that requires a multidisciplinary approach involving an obstetrician, surgeon and oncologist. Management should be along the same principles as in non-pregnant patients and delay is not justifiable. Mastectomy and axillary clearance is the best option, followed by chemotherapy, which is safe after the first trimester. Radiation if required should be delayed until after delivery of the baby. We present here our experience with 6 patients who presented with breast cancer during pregnancy. Five patients refused any treatment until after delivery, while one underwent only a mastectomy and axillary clearance. The outcome was poor; all of them died between 14 months and 52 months. The poor outcome probably reflects the late stage at presentation in four of the patients (State 3 and 4) rather than the delay in treatment, while delay in treatment in the two who presented with early cancer (Stage 1 and 2) led to a more advanced stage after delivery.

    Dihydropteroate synthase (dhps) and dihydrofolate reductase (dhfr) alleles were typed in 67 Malaysian Plasmodium falciparum isolates. The isolates were collected from two geographically distinct locations: 51 from Sabah, Malaysian Borneo, where sulfadoxine/pyrimethamine (SDX/PYR) is used to treat uncomplicated malaria and 16 from Peninsular Malaysia where in vivo resistance to SDX/PYR has been reported. A total of seven dhps alleles were identified with no significant difference in allele frequency between the 2 populations. Two of the dhps alleles described here have not been previously reported. Four dhfr alleles were detected in 67 P. falciparum isolates. Eighty-seven percent of the isolates from the Peninsula, where clinical SDX/PYR failure has been reported, had dhfr alleles with triple point mutations while all of the isolates from Sabah had dhfr alleles with 2 or less point mutations. The difference in dhfr allele frequency between the two populations was highly significant. There was no correlation between in vitro PYR response and accumulation of dhfr point mutations.

    The prevalence of sexually transmitted diseases (STD) among female drug abusers was studied by screening 130 new inmates of a rehabilitation centre. Data was collected using a structured questionnaire, physical examination and specimen collection for laboratory investigation at the Community Medicine Clinic of HUSM. The majority (64.6%) were Malays and self-confessed sex workers (77.7%). A high prevalence of syphilis (50.8%), hepatitis B (52.2%), moniliasis (23.8%), trichomoniasis (19.2%) and gonococcal vaginitis (8.5%) was noted. More than half of them harbour 2 or more STDs. Six subjects, of whom 5 were Malays, were HIV positive. The evidence indicates that female drug abusers need a thorough screening for STD followed by an aggressive treatment regimen. Since the majority of them were born Muslims, they should have access to spiritual counselling and rehabilitation, stressing on repentance, and adopting a compassionate and forgiving approach.
