    Rasool NB, Larralde G, Gorziglia MI
    Arch Virol, 1993;133(3-4):275-82.
    PMID: 8257289
    The VP4 genetic groups of 151 field strains of human rotaviruses obtained from infants and young children with diarrhea from four locations in Malaysia were analyzed. The strains were adapted to growth in tissue culture and studied further by molecular hybridization of northern blotted RNA to PCR-generated cDNA probes representing amino acids 84-180 of the KU strain VP4, 83-181 of the DS-1 strain VP4, and 83-180 of either the 1076 or K8 strain VP4, representing VP4 genetic groups 1-4 (P1A, P1B, P2, and P3), respectively. The majority (79% of the field strains hybridized with the KU VP4 genetic group 1 probe and were associated with G1, G3, G4, untypable, or mixed G serotypes. VP4 genetic group 1 (P1A) strains were the most common in all locations in Malaysia between 1978-1988. Three strains which exhibited G3 and subgroup I specificity hybridized with the K8 VP4 genetic group 4 probe. These three VP4 genetic group 4 (P3) strains were detected in two different years and locations, extending the initial detection of this VP4 genetic group (the K8 strain) in Japan to a larger geographical area of Asia.

    Rasool NB, Hamzah M, Jegathesan M, Wong YH, Qian Y, Green KY
    J Med Virol, 1994 Jul;43(3):209-11.
    PMID: 7931180
    Stool specimens from 334 infants and young children hospitalized with diarrhea in the General Hospital, Kuala Lumpur, Malaysia between August and November, 1987 were analyzed for the presence of rotavirus double-stranded (ds) RNA by polyacrylamide gel electrophoresis. Of the 334 specimens analyzed, 32 (9.6%) were positive for rotavirus RNA. One specimen (designated G147) exhibited a ds RNA electropherotype profile characteristic of Group C rotavirus and was selected for further characterization. In Northern blot hybridization studies, the gene 5 segment of strain G147 hybridized with a cDNA probe generated from the cloned gene 5 (which encodes the VP6 inner capsid protein that is group specific) of porcine Group C rotavirus strain Cowden, confirming the classification of strain G147 in Group C. The association of Group C rotavirus with diarrheal illness in Malaysia is consistent with earlier studies that suggest a global distribution of this virus and supports the need for additional epidemiologic studies.

  3. Determination of a universal nucleic acid extraction procedure for PCR detection of gastroenteritis viruses in faecal specimens
    Rasool NB, Monroe SS, Glass RI
    J Virol Methods, 2002 Feb;100(1-2):1-16.
    PMID: 11742648
    Four nucleic acid extraction protocols were examined for their suitability for extraction of the ssRNA, dsRNA and dsDNA genomes of gastroenteritis viruses, for PCR detection. Protocol (A), employed specimen lysis with guanidinium thiocyanate, extraction with phenol-chloroform-isoamyl alcohol and nucleic acid purification by size-fractionated silica particles. Protocol (B), utilised specimen lysis with guanidinium thiocyanate and nucleic acid purification by silica, followed by phenol-chloroform-isoamyl alcohol extraction. Protocol (C), employed specimen lysis with guanidinium thiocyanate and nucleic acid purification by RNAID glass powder. Protocol (D), employed specimen lysis with sodium dodecyl sulphate, proteinase K digestion and extraction with phenol-chloroform-isoamyl alcohol. Of the four protocols, (B) appeared to be a suitable candidate 'universal' nucleic acid extraction procedure for PCR detection of different viral agents of gastroenteritis in a single nucleic acid extract of a faecal specimen, irrespective of genome composition. Omission of the phenol-chloroform extraction step did not affect negatively the ability of protocol (B) to allow PCR detection of gastroenteritis viruses in faecal specimens. PCR detection of NLVs, astroviruses, rotaviruses and adenoviruses, in single nucleic acid extracts of faecal specimens obtained from the field, confirmed the universality of the modified protocol (B). We propose the modified protocol (B) as a 'universal' nucleic acid extraction procedure, for monoplex PCR detection of gastroenteritis viruses in single nucleic acid extracts of faecal specimens and for development of multiplex PCR for their simultaneous detection.

  4. Fulltext Abdominal tuberculosis: a presumptive diagnosis
    Ramanathan M, Wahinuddin S, Safari E, Sellaiah SP
    Singapore Med J, 1997 Sep;38(9):364-8.
    PMID: 9407759
    Abdominal tuberculosis (TB) is common. But the diagnosis of abdominal TB is fraught with difficulties as it is often not possible to get a microbiological confirmation of the infection. We therefore undertook this study to highlight those pertinent clinical and laboratory features which would enable one to make a provisional diagnosis of abdominal TB early, to pave way for a trial of anti-tuberculosis chemotherapy.

  5. Increase number of mitochondrion-like organelle in symptomatic Blastocystis subtype 3 due to metronidazole treatment
    Raman K, Kumar S, Chye TT
    Parasitol Res, 2016 Jan;115(1):391-6.
    PMID: 26481491 DOI: 10.1007/s00436-015-4760-0
    Blastocystis sp., an intestinal organism is known to cause diarrhea with metronidazole regarded as the first line of treatment despite reports of its resistance. The conflicting reports of variation in drug treatment have been ascribed to subtype differences. The present study evaluated in vitro responses due to metronidazole on ST3 isolated from three symptomatic and asymptomatic patients, respectively. Symptomatic isolates were obtained from clinical patients who showed symptoms such as diarrhea and abdominal bloating. Asymptomatic isolates from a stool survey carried out in a rural area. These patients had no other pathogens other than Blastocystis. Ultrastructural studies using transmission electron microscopy (TEM) and scanning electron microscopy (SEM) revealed drug-treated ST3 from symptomatic patients were irregular and amoebic with surface showing high-convoluted folding when treated with metronidazole. These organisms had higher number of mitochondrion-like organelle (MLO) with prominent cristae. However, the drug-treated ST3 from asymptomatic persons remained spherical in shape. Asymptomatic ST3 showed increase in the size of its central body with the MLO located at the periphery.

  6. Fulltext Role of ErbB1 in the Underlying Mechanism of Lapatinib-Induced Diarrhoea: A Review
    Raja Sharin RNFS, Khan J, Ibahim MJ, Muhamad M, Bowen J, Wan Mohamad Zain WNI
    Biomed Res Int, 2022;2022:4165808.
    PMID: 35800225 DOI: 10.1155/2022/4165808
    Lapatinib, an orally administered small-molecule tyrosine kinase inhibitor (SM-TKI), is an effective treatment for ErbB2-positive breast cancer. However, its efficacy as one of the targeted cancer therapies has been hampered by several adverse effects, especially gastrointestinal toxicity, commonly manifested as diarrhoea. Although it can be generally tolerated, diarrhoea is reported as the most common and most impactful on a patient's quality of life and associated with treatment interruption. Severe diarrhoea can result in malabsorption, leading to dehydration, fatigue, and even death. ErbB1 is an epidermal growth factor profoundly expressed in normal gut epithelium while lapatinib is a dual ErbB1/ErbB2 tyrosine kinase inhibitor. Thus, ErbB1 inhibition by lapatinib may affect gut homeostasis leading to diarrhoea. Nevertheless, the underlying mechanisms remain unclear. This review article provides evidence of the possible mechanisms of lapatinib-induced diarrhoea that may be related to/or modulated by ErbB1. Insight regarding the involvement of ErbB1 in the pathophysiological changes such as inflammation and intestinal permeability as the underlying cause of diarrhoea is covered in this article.

  7. Fulltext Torsade de pointes and sudden death associated with diabetic autonomic diarrhoea--a case report
    Quek DK, H'ng PK
    Singapore Med J, 1993 Jun;34(3):266-70.
    PMID: 8266190
    A 68-year-old diabetic and hypertensive woman presented with chronic autonomic diarrhoea, syncope and palpitations which were associated with QT prolongation and recurrent episodes of torsade de pointes. She was on glibenclamide, indapamide and probucol (for type V hyperlipidaemia). Despite intravenous infusions of potassium, lignocaine and amiodarone, the unstable rhythm persisted. However, intravenous magnesium sulphate with small doses of intravenous propranolol terminated the torsade de pointes. She was stabilised but following discharge she relapsed, and upon re-admission, succumbed to intractable ventricular fibrillation. Early recognition and aggressive treatment of this condition is emphasised. Multiple aggravating factors ie autonomic diarrhoea resulting in severe potassium and magnesium depletion, kaliuretic effect of indapamide, probable QT prolongation associated with diabetic autonomic neuropathy and probucol; probable underlying coronary artery disease and heightened emotional and sympathetic discharge could have contributed to this very unstable ventricular arrhythmia and sudden death.

  8. Fulltext The importance of breastfeeding in rotaviral diarrhoeas
    Prameela KK, Vijaya LR
    Malays J Nutr, 2012 Apr;18(1):103-11.
    PMID: 23713234 MyJurnal
    Globally, rotaviral vaccines in use today have contributed to the reduction of the incidence of rotaviral diarrhoeas. Despite the substantial protection conferred by the current vaccines against the rotaviral strains, it is only prudent to recognise that other protective factors, like breastfeeding, also provide some degree of protection against this disease. This article has attempted to review some important mechanisms of protection in breast milk against the rotaviruses and highlight the oft forgotten non-immunoglobulin fraction in breast milk as an additional tool of protection against rotavirus disease. The adaptive capacity of breast milk to environment is another compelling reason to continue breastfeeding as it can usefully complement and be significant in the use of many vaccines. Vital immunoprotective constituents in breast milk beneficially protect the infant by initiating and strengthening many immune responses and should be borne in mind as essential tools of defence even in an era where vaccines play a pivotal role in the combat against certain diseases. It is impressive that besides nutritive advantages, the suckling infant enjoys appreciable immunoprotection via exclusive breastfeeding.

  9. Healthcare seeking during travel: an analysis by the GeoSentinel surveillance network of travel medicine providers
    Piyaphanee W, Stoney RJ, Asgeirsson H, Appiah GD, Díaz-Menéndez M, Barnett ED, et al.
    J Travel Med, 2023 May 18;30(3).
    PMID: 36637429 DOI: 10.1093/jtm/taad002
    BACKGROUND: International travellers may seek care abroad to address health problems that arise during their trip or plan healthcare outside their country of residence as medical tourists.

    METHODS: Data were collected on travellers evaluated at GeoSentinel Network sites who reported healthcare during travel. Both unplanned and planned healthcare were analysed, including the reason and nature of healthcare sought, characteristics of the treatment provided and outcomes. Travellers that presented for rabies post-exposure prophylaxis were described elsewhere and were excluded from detailed analysis.

    RESULTS: From May 2017 through June 2020, after excluding travellers obtaining rabies post-exposure prophylaxis (n= 415), 1093 travellers reported care for a medical or dental issue that was an unanticipated part of the travellers' planned itinerary (unplanned healthcare). Travellers who sought unplanned healthcare abroad had frequent diagnoses of acute diarrhoea, dengue, falciparum malaria and unspecified viral syndrome, and obtained care in 131 countries. Thirty-four (3%) reported subsequent deterioration and 230 (21%) reported no change in condition; a third (n = 405; 37%) had a pre-travel health encounter. Forty-one travellers had sufficient data on planned healthcare abroad for analysis. The most common destinations were the US, France, Dominican Republic, Belgium and Mexico. The top reasons for their planned healthcare abroad were unavailability of procedure at home (n = 9; 19%), expertise abroad (n = 9; 19%), lower cost (n = 8; 17%) and convenience (n = 7; 15%); a third (n = 13; 32%) reported cosmetic or surgical procedures. Early and late complications occurred in 14 (33%) and 4 (10%) travellers, respectively. Four travellers (10%) had a pre-travel health encounter.

    CONCLUSIONS: International travellers encounter health problems during travel that often could be prevented by pre-travel consultation. Travellers obtaining planned healthcare abroad can experience negative health consequences associated with treatments abroad, for which pre-travel consultations could provide advice and potentially help to prevent complications.

  10. Small circular single stranded DNA viral genomes in unexplained cases of human encephalitis, diarrhea, and in untreated sewage
    Phan TG, Mori D, Deng X, Rajindrajith S, Ranawaka U, Fan Ng TF, et al.
    Virology, 2015 Aug;482:98-104.
    PMID: 25839169 DOI: 10.1016/j.virol.2015.03.011
    Viruses with small circular ssDNA genomes encoding a replication initiator protein can infect a wide range of eukaryotic organisms ranging from mammals to fungi. The genomes of two such viruses, a cyclovirus (CyCV-SL) and gemycircularvirus (GemyCV-SL) were detected by deep sequencing of the cerebrospinal fluids of Sri Lankan patients with unexplained encephalitis. One and three out of 201 CSF samples (1.5%) from unexplained encephalitis patients tested by PCR were CyCV-SL and GemyCV-SL DNA positive respectively. Nucleotide similarity searches of pre-existing metagenomics datasets revealed closely related genomes in feces from unexplained cases of diarrhea from Nicaragua and Brazil and in untreated sewage from Nepal. Whether the tropism of the cyclovirus and gemycircularvirus reported here include humans or other cellular sources in or on the human body remains to be determined.

  11. Potential role of flavonoids against SARS-CoV-2 induced diarrhea
    Paul AK, Jahan R, Bondhon TA, Jannat K, Hasan A, Rahmatullah M, et al.
    Trop Biomed, 2021 Sep 01;38(3):360-365.

    COVID-19, caused by the SARS-CoV-2 virus, can lead to massive inflammation in the gastrointestinal tract causing severe clinical symptoms. SARS-CoV-2 infects lungs after binding its spike proteins with alveolar angiotensin-converting enzyme 2 (ACE2), and it also triggers inflammation in the gastrointestinal tract. SARS-CoV-2 invades the gastrointestinal tract by interacting with Toll-like receptor-4 (TLR4) that induces the expression of ACE2. The influx of ACE2 facilitates cellular binding of more SARS-CoV-2 and causes massive gastrointestinal inflammation leading to diarrhea. Diarrhea prior to COVID-19 infection or COVID-19-induced diarrhea reportedly ends up in a poor prognosis for the patient. Flavonoids are part of traditional remedies for gastrointestinal disorders. Preclinical studies show that flavonoids can prevent infectious diarrhea. Recent studies show flavonoids can inhibit the multiplication of SARS-CoV-2. In combination with vitamin D, flavonoids possibly activate nuclear factor erythroid-derived-2-related factor 2 that downregulates ACE2 expression in cells. We suggest that flavonoids have the potential to prevent SARS-CoV-2 induced diarrhea.

  12. Fulltext In vitro and In vivo Antioxidant Evaluation and Estimation of Total Phenolic, Flavonoidal Content of Mimosa pudica L
    Patro G, Bhattamisra SK, Mohanty BK, Sahoo HB
    Pharmacognosy Res, 2016;8(1):22-8.
    PMID: 26941532 DOI: 10.4103/0974-8490.171099
    OBJECTIVE: Mimosa pudica Linn. (Mimosaceae) is traditionally used as a folk medicine to treat various ailments including convulsions, alopecia, diarrhea, dysentery, insomnia, tumor, wound healing, snake bite, etc., Here, the study was aimed to evaluate the antioxidant potential of M. pudica leaves extract against 2, 2-diphenyl-1-picrylhydrazyl (DPPH) (in vitro) and its modulatory effect on rat brain enzymes.
    MATERIALS AND METHODS: Total phenolic, flavonoid contents, and in vitro antioxidant potential against DPPH radical were evaluated from various extracts of M. pudica leaves. In addition, ethyl acetate extract of Mimosa pudica leaves (EAMP) in doses of 100, 200, and 400 mg/kg/day were administered orally for 7 consecutive days to albino rats and evaluated for the oxidative stress markers as thiobarbituric acid reactive substances (TBARS), superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH) from rat brain homogenate.
    RESULTS: The ethyl acetate extract showed the highest total phenolic content and total flavonoid content among other extracts of M. pudica leaves. The percentage inhibition and IC50 value of all the extracts were followed dose-dependency and found significant (P < 0.01) as compared to standard (ascorbic acid). The oxidative stress markers as SOD, CAT, and GSH were increased significantly (P < 0.01) at 200 and 400 mg/kg of EAMP treated animals and decreased significantly the TBARS level at 400 mg/kg of EAMP as compared to control group.
    CONCLUSION: These results revealed that the ethyl acetate extract of M. pudica exhibits both in vitro antioxidant activity against DPPH and in vivo antioxidant activity by modulating brain enzymes in the rat. This could be further correlated with its potential to neuroprotective activity due to the presence of flavonoids and phenolic contents in the extract.
    SUMMARY: Total phenolic, flavonoid contents and in-vitro antioxidant potential were evaluated from various extracts of M. pudica leaves. Again, in-vivo antioxidant evaluation from brain homogenate on oxidative stress markers as TBARS, SOD, CAT and GSH from rat was investigated. Our findings revealed that M. pudica possesses both in-vitro and in-vivo antioxidant activity due to presence of phenolics and flavonoids.

    PMID: 2828895
    A prospective clinical study comparing 74 cases of rotavirus-associated diarrhoea and 100 cases of non-rotavirus-associated diarrhoea revealed a higher incidence of vomiting to be the only significant difference in the former. Bloody stools were seen in about 5-10%, fever in about two-thirds and respiratory symptoms in a quarter of cases regardless of aetiology. The overwhelming majority had mild dehydration of the isonatremic type. Hypokalemia was noted in a quarter of the cases in both groups.

    The first, to our knowledge, case of the aseptic abscesses syndrome as a complication of traveler's diarrhea after a trip to Malaysia is presented. The patient failed to respond to several antimicrobials. The diagnosis was histologically confirmed and the patient only responded to immunomodulatory therapy with corticosteroids and methotrexate. Travel physicians should be aware of this entity reviewed herein in the context of traveler's diarrhea.

    J Med Microbiol, 1987 May;23(3):193-8.
    PMID: 3585956
    Studies were performed on a cytotoxin (CT) from human strains of Campylobacter jejuni isolated in Malaysia. CT was detected by cytopathic effect (CPE) on HeLa cells at titres from 8 to 32, in culture filtrates from 14 (48%) of 29 human isolates. The CPE correlated well with a quantitative 51Cr-release assay where a specific release of 54-68% was noted. CT production was lost after 5-7 subcultures. CT activity was also detected in 5 (26%) of 19 faecal filtrates from which CT-producing isolates were subsequently obtained. The mol. wt of CT was estimated by Sephadex G-50 chromatography to be greater than 30,000. In a suckling-mouse assay, CT consistently failed to demonstrate fluid accumulation after intragastric inoculation of culture filtrate. The Removable Intestinal Tie Adult Rabbit Diarrhoea (RITARD) assay was also used. Rabbits given CT-producing strains of C. jejuni developed bacteraemia and severe watery mucus-containing diarrhoea for the duration of the experiment with death of some animals. Rabbits given CT non-producing strains had less severe disease and none died. Rabbits given partially-purified CT had diarrhoea for 3 days but none died.

    Family Physician, 1991;3:28-30.
    A study was conducted in an urban slum area of Kuala Lumpur, the capital of Malaysia, to determine the health status of the children under 6 years old and the knowledge and practice associated with diarrhoeal diseases and use of oral rehydration salts (ORS) among mothers in the area. It was seen that the health status of the children was poor with one fifth of them born underweight, 33% experiencing more than 6 spells of illness per year and a high percentage of them suffering from diarrhoeal diseases (4.3%). Child care practice was associated with urban lifestyles with early weaning, short term breast-feeding and early introduction of solid and bottle feeding. Knowledge and practice of mothers concerning child care was inadequate to support healthy living. Knowledge of diarrhoeal diseases and the effectivenss of oral rehydration salts was poor. Only 47.7% of mothers knew about ORS and 27.8% ever used it when their chidlren suffered from diarrhoea. Health care system dependence was shown by the high percentage of mothers immediately bringing to a doctor's attention (75.6%).

  17. Fulltext A pentaplex PCR assay for the detection and differentiation of Shigella species
    Ojha SC, Yean Yean C, Ismail A, Singh KK

    PMID: 23509722 DOI: 10.1155/2013/412370
    The magnitude of shigellosis in developing countries is largely unknown because an affordable detection method is not available. Current laboratory diagnosis of Shigella spp. is laborious and time consuming and has low sensitivity. Hence, in the present study, a molecular-based diagnostic assay which amplifies simultaneously four specific genes to identify invC for Shigella genus, rfc for S. flexneri, wbgZ for S. sonnei, and rfpB for S. dysenteriae, as well as one internal control (ompA) gene, was developed in a single reaction to detect and differentiate Shigella spp. Validation with 120 Shigella strains and 37 non-Shigella strains yielded 100% specificity. The sensitivity of the PCR was 100 pg of genomic DNA, 5.4 × 10(4) CFU/ml, or approximately 120 CFU per reaction mixture of bacteria. The sensitivity of the pentaplex PCR assay was further improved following preincubation of the stool samples in gram-negative broth. A preliminary study with 30 diarrhoeal specimens resulted in no cross-reaction with other non-Shigella strains tested. We conclude that the developed pentaplex PCR assay is robust and can provide information about the four target genes that are essential for the identification of the Shigella genus and the three Shigella species responsible for the majority of shigellosis cases.

    Proton-pump inhibitors (PPI) and histamine-2 receptor antagonists (H2RA) are common acid suppressants used in gastrointestinal disorders. The trend of usage in Malaysia has changed from predominantly H2RA to PPI from 2007 to 2008, 3.46 versus 2.87 and 2.99 versus 3.24 DDD (Defined Daily Dose)/1000 population/day respectively. This raises concerns as PPI overutilization amounts to higher cost expenditure and are associated with various untoward consequences such as Clostridium difficile-associated diarrhea, pneumonia, and osteoporosis.

  19. Clinical and laboratory presentation of malaria: an analysis of one thousand subjects with malaria parasitaemia
    O'Holohan DR
    J Trop Med Hyg, 1976 Sep;79(9):191-6.
    PMID: 794512
    In the context of this study the ethnic origin of the patients revealed no noteworthy difference in the clinical reaction to the parasite; neither did age or sex of the patients. Any minor differences whcih appeared in length of history before seeking treatment and frequency of repeat attacks were more a reflection of the cultural pattern of response to illness (i.e. resort to traditional medicines) and the distance between the patient's home and the doctor rather than any altered response on the part of the host to the parasite. However, the fact that about 35 per cent of all the episodes had a history of eight or more days (about 10 per cent more than 30 days) suggest that more "malaria consciousness" is called for in what is after all an endemic malaria area. The value (and necessity) of repeated examination of the blood to detect the parasite is confirmed but it is also encouraging to note that in 84% of cases a single careful examination of the blood revealed the parasite. Since in 49% of our malaria episodes the patient was afebrile when the parasite was discovered, it is obvious that in outpatient practice especially blood should be examined when the patient presents for treatment, irrespective of the presence or absence of pyrexia. As always, a prerequisite to the diagnosis of malaria is an awareness of its possible presence.
