    PMID: 28400860 DOI: 10.1186/s13099-017-0166-0
    BACKGROUND: There are multiple etiologies responsible for infectious gastroenteritis causing acute diarrhea which are often under diagnosed. Also acute diarrhea is one of the major causes of morbidity and mortality among children less than 5 years of age.

    METHODS: In our study, fecal samples (n = 130) were collected from children (<5 years) presenting with symptoms of acute diarrhea. Samples were screened for viral, bacterial, and parasitic etiologies. Rotavirus and Adenovirus were screened by immunochromatographic tests. Diarrheagenic Escherichia coli (EPEC, EHEC, STEC, EAEC, O157, O111), Shigella spp., Salmonella spp., Vibrio cholera, Cryptosporidium spp., and Giardia spp. were detected by gene-specific polymerase chain reaction.

    RESULTS: Escherichia coli was detected to be the major etiological agent (30.07%) followed by Rotavirus (26.15%), Shigella (23.84%), Adenovirus (4.61%), Cryptosporidium (3.07%), and Giardia (0.77%). Concurrent infections with two or more pathogens were observed in 44 of 130 (33.84%) cases with a predominant incidence particularly in <2-year-old children (65.90%) compared to children of 2-5 years age group (34.09%). An overall result showed significantly higher detection rates among children with diarrhea in both combinations of two as well as three infections concurrently (p = 0.004915 and 0.03917, respectively).

    CONCLUSION: Suspecting possible multiple infectious etiologies and diagnosis of the right causative agent(s) can aid in a better pharmacological management of acute childhood diarrhea. It is hypothesized that in cases with concurrent infections the etiological agents might be complementing each other's strategies of pathogenesis resulting in severe diarrhea that could be studied better in experimental infections.

  3. Fulltext Trend Analysis of Travel Medicine Topics Presented at an International Tropical Medicine Conference
    Asawapaithulsert P, Flaherty GT, Piyaphanee W
    Am J Trop Med Hyg, 2022 Aug 17;107(2):492-494.

    Prior to the COVID-19 pandemic, there was a rapid increase in international travel. Travel medicine is a branch of preventive medicine focusing on risk assessment pre-travel, during travel and post-travel with the aim of promoting health and preventing adverse health outcomes. Travel medicine specialists inform travelers about potential health risks and mitigate infectious disease risks such as travelers' diarrhea, yellow fever, and malaria. Travel medicine topics were popular in the American Society of Tropical Medicine and Hygiene conferences between 2016 and 2020, and now comprise approximately 2% of all presentations. Most topics related to the post-travel assessment (50%), followed by diseases contracted during travel (26%), and pre-travel assessment and consultation (24%). Our analysis of the 10 sub-domains of travel medicine issues found that malaria (26%) and immunization (12%) were represented to the greatest extent. We anticipate that both travel and tropical medicine fields will regain their popularity after recovery from the pandemic.

  4. The effect of infection of hatched blastocyst bovine embryos with border disease and bovine viral diarrhea viruses
    Mabruk MJ, Sheahan B, Atkins G
    Southeast Asian J. Trop. Med. Public Health, 2006 Jan;37(1):113-9.
    PMID: 16771222
    The effect of infection with teratogenic viruses at early stages of pregnancy is not fully understood. This study aimed to look at the effect of infection with teratogenic viruses such as bovine viral diarrhea virus (BVDV) and border disease virus (BDV), on early stage embryos at the hatched blastocyst stage. BVDV and BDV are known to cross the placenta of infected mothers and lead to congenital defects and death of developing fetuses. This study can be a good model for better understanding the effects of other teratogenic viruses such as Rubella virus in humans.

  5. Fulltext Trichuris Dysentery Syndrome: evidence that it may be underdiagnosed in Kelantan
    Noorizan AM, Mahendra Raj S
    Med J Malaysia, 2001 Mar;56(1):53-7.
    PMID: 11503297
    The prevalence rate of trichuriasis in children in certain areas of Kelantan is high. However the Trichuris Dysentery Syndrome (TDS), a condition in children characterized by chronic diarrhoea, stunting and anaemia is said to be rare. A recent change in policy at our institution to lower the threshold for undertaking colonoscopy in children with chronic diarrhoea resulted in the detection of 6 cases of TDS in less than a year. The median age was 7 years (range 3-13) and the median duration of symptoms before diagnosis was 2 years (range 1-8). The insidious nature of TDS and the low level of awareness of this condition even among health care workers may result in considerable underdiagnosis.

  6. Fulltext Campylobacter jejuni as a cause of diarrhoea in Kuala Lumpur, Malaysia
    Lim YS, Jegathesan M, Wong YH
    Med J Malaysia, 1984 Dec;39(4):285-8.
    PMID: 6544934
    The incidence of Campylobacter jejuni in patients with and without diarrhoea was studied in Kuala Lumpur, Malaysia. C. jejuni was recovered from 3.8% and 4.3% of diarrhoeal stools of children and adults, respectively. From the patients without diarrhoea, the relative isolation rates for children and adults were 2.6% and 0%, respectively. Dual infections occurred in two children, with Salmonella and enteropathogenic Escherichia coli being the other enteric pathogen in each case. Cary-Blair medium was found to be an effective transport medium in recovering C. jejuni. Campylobacter enteritis occurred in patients of various age groups, indicating that this organism should be sought routinely by diagnostic laboratories in faecal specimens from patients with diarrhoea.

    Southeast Asian J. Trop. Med. Public Health, 1982 Sep;13(3):306-18.
    PMID: 7163834
    Diarrhoea up till now is still a major problem in Southeast Asia with high morbidity and mortality, particularly among children under 5 years of age, with the peak in children between 6 - 24 months. In Indonesia, in 1981, it was estimated that there are 60 million episodes with 300,000 - 500,000 deaths. In the Philippines, diarrhoea ranks as a second cause of morbidity (600 per 100,000 in 1974) and second cause of infant mortality (5 per 1,000 in 1974). In Thailand, in 1980, the morbidity rate was 524 per 100,000 and the mortality rate 14 per 100,000. In Malaysia, in 1976, diarrhoea was still ranking number 5 (3.1%) as a cause of total admission and number 9 (2.2%) as a cause of total deaths. In Singapore, diarrhoea still ranks number 3 as a cause of deaths (4% of total deaths). In Bangladesh, the overall attack rates imply a prevalence of 2.0% for the entire population, with the highest for under 5 groups i.e. 4.1%. The diarrhoea episode in rural population is 85.4%, 39% of them are children under 5. The most common enteropathogens found in all countries are rotavirus followed by Enterotoxigenic E. coli, Vibrio spp., Salmonella spp., Shigella spp. and Campylobacter. Malnutrition and decline of giving breast-feeding play an important role in causing high morbidity, besides socio-economic, socio-cultural and poor environmental sanitation.

    Diarrheal diseases (DD) are leading causes of disease burden, death, and disability, especially in children in low-income settings. DD can also impact a child's potential livelihood through stunted physical growth, cognitive impairment, and other sequelae. As part of the Global Burden of Disease Study, we estimated DD burden, and the burden attributable to specific risk factors and particular etiologies, in the Eastern Mediterranean Region (EMR) between 1990 and 2013. For both sexes and all ages, we calculated disability-adjusted life years (DALYs), which are the sum of years of life lost and years lived with disability. We estimate that over 125,000 deaths (3.6% of total deaths) were due to DD in the EMR in 2013, with a greater burden of DD in low- and middle-income countries. Diarrhea deaths per 100,000 children under 5 years of age ranged from one (95% uncertainty interval [UI] = 0-1) in Bahrain and Oman to 471 (95% UI = 245-763) in Somalia. The pattern for diarrhea DALYs among those under 5 years of age closely followed that for diarrheal deaths. DALYs per 100,000 ranged from 739 (95% UI = 520-989) in Syria to 40,869 (95% UI = 21,540-65,823) in Somalia. Our results highlighted a highly inequitable burden of DD in EMR, mainly driven by the lack of access to proper resources such as water and sanitation. Our findings will guide preventive and treatment interventions which are based on evidence and which follow the ultimate goal of reducing the DD burden.

  10. Fulltext Estimates of the burden of rotavirus disease in Malaysia
    Hsu VP, Abdul Rahman HB, Wong SL, Ibrahim LH, Yusoff AF, Chan LG, et al.
    J Infect Dis, 2005 Sep 1;192 Suppl 1:S80-6.
    PMID: 16088810
    BACKGROUND: Accurate national estimates of the disease burden associated with rotavirus diarrhea are essential when considering implementation of a rotavirus vaccination program. We sought to estimate rotavirus disease-associated morbidity and mortality in Malaysia, using available sources of information.
    METHODS: We analyzed national data from the Ministry of Health (Kuala Lumpur, Malaysia) to derive rates of hospitalization, clinic visits, and deaths related to acute gastroenteritis (AG) among children <5 years of age. The number of events attributable to rotavirus infection was estimated by multiplying age-stratified rates of detection of rotavirus from 2 hospital surveillance sites by national data.
    RESULTS: In 1999 and 2000, an average of 13,936 children (1 in 187 children) were hospitalized annually for AG. Surveillance of visits to outpatient clinics for AG identified an average of 60,342 such visits/year between 1998 and 2000. The AG-associated mortality rate was 2.5 deaths/100,000 children. On the basis of the finding that 50% of children were hospitalized for rotavirus diarrhea, we estimated that 1 in 61 children will be hospitalized for rotavirus disease and that 1 in 37 children will seek treatment as an outpatient.
    CONCLUSIONS: Among Malaysian children, there is a significant burden associated with AG- and rotavirus disease-related hospitalizations and outpatient visits, and this burden potentially could be prevented by the use of rotavirus vaccines.

  11. Fulltext Plesiomonas shigelloides associated with diarrhoeal disease in Malaysian children
    Lim YS, Young LJ, Balakrishnan S
    Singapore Med J, 1987 Dec;28(6):534-6.
    PMID: 3441796
    Plesiomonas shigelloides was isolated from 5 (2.1%) of the 234 children with diarrhoea and none of the 230 controls. In one child, the organism was found in association with Salmonella. Two strains had Shigella sonnei phase I antigen. All the strains were susceptible to the aminoglycosides, cephalosporins, nalidixic acid, nitrofurantoin, chloramphenicol and cotrimoxazole; but resistant to the penicillins. Alkaline peptone water enrichment subcultured to desoxycholale citrate agar proved to be a useful method for isolating this organism from faeces. As the roie of P. shigelloides in causing gastrointestinal disease remains controversial, further studies are necessary to determine its enteropathogenicily.

  12. Post-COVID-19 cryptosporidiosis: A serious risk or mere association?
    Enas AE, Hadel MA, Emad AA, Ibrahim BE, Morsy S, Noha MA
    Trop Biomed, 2023 Jun 01;40(2):199-207.
    PMID: 37650408 DOI: 10.47665/tb.40.2.012
    Post-COVID-19 conditions encompass a wide range of health problems, including enteritis, but their association with parasitic infections has not yet been investigated. This study analyzed gastrointestinal symptoms, medical histories, fecal Cryptosporidium oocysts, and the history of COVID-19 infection in patients who attended the Faculty of Medicine, Cairo University, from January to July 2021. Fecal biomarkers, including H. pylori, occult blood, fecal calprotectin (FCAL), and TNF-a, were measured, and Cryptosporidium spp. genotypes were molecularly characterized among post-COVID-19 patients using RFLP. Preliminary results from 210 post-COVID-19 patients revealed that group 1 (Cryptosporidiumpositive) (n = 49) and group 2 (Cryptosporidium-negative) (n = 161) showed no significant difference in the prevalence rate of diabetes mellitus (DM). While group 2 was linked to diarrhea, only infections with Cryptosporidium post-COVID-19 were related to chronic diarrhea, vomiting, and weight loss. A total of 220 healthy subjects served as negative controls. Administering azithromycin, hydroxychloroquine, and ivermectin was significantly related to an increased risk of Cryptosporidium infection in group 1, whereas only azithromycin was more frequently recorded in group 2. Antioxidant supplementation insignificantly affected the incidence of cryptosporidiosis. Cryptosporidiosis with a history of COVID-19 was linked to H. pylori infections, increased inflammatory biomarkers (FCAL and TNF-a), and occult blood when compared with group 2. Cryptosporidium genotype 1 was the most commonly occurring subset in individuals with post-COVID-19. The findings demonstrated that aggravating gastrointestinal manifestations, increased fecal biomarkers and anti-COVID-19 therapeutic interventions are significantly related to the existence of Cryptosporidium oocysts in patients with post-COVID-19, indicating the predominance of.

  13. 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.

    Globally, rotaviruses are the single most important etiologic agents of severe childhood dehydrating diarrhea that accounts for more than 125 million of cases, 25-55% of all hospital admissions for diarrhea and ≈600,000 deaths every year. In Bangladesh, while overall diarrhea related deaths are declining, the proportion of diarrhea deaths due to rotavirus is increasing. This study was aimed at estimating the burden of rotavirus diarrhea and isolating the genotypes of rotavirus in a children hospital of Bangladesh; thereby endorsing a logical search for an appropriate rotavirus vaccine. This cross sectional study was carried out in the Institute of Child and Mother Health, Matuail, Dhaka, Bangladesh during 2006-2007. Children aged between one month and five years suffering form diarrhea were enrolled in the study. Stool samples were analyzed by ELISA for rotavirus antigen. The rotavirus-positive samples were further analyzed for genotype determination. Among 656 stool samples, 39.5% samples were positive for rotavirus antigen. The mean age of the children studied was 12±9.9 months; the peak being in the second half of infancy. G2 was identified as the most dominant genotype (45.5%) followed by G1 (24.8%), G12 (9.6%), G9 (8.5%) and G4 (2.1%) genotypes. Since G2 were found to be the predominant circulating rotavirus strain in this study and some other studies in Bangladesh, the recommended vaccine for prevention of rotavirus infection in Bangladesh should cover this strain to have maximum effectiveness.

    Med J Malaysia, 2009 Mar;64(1):83-5.
    PMID: 19852331 MyJurnal
    A five-month-old Indian girl, product of consanguineous marriage, presented with diarrhoea with an onset within two days after birth, severe malnutrition and metabolic acidosis. The diarrhoea persisted even with lactose-free formula, amino acid-based formula and glucose-containing oral rehydration solution, but stopped when fasted. She required prolonged parenteral nutrition. Fructose and glucose tolerance tests were performed, confirming the child was able to absorb and metabolize fructose but not glucose, indicating a diagnosis of glucose-galactose malabsorption. This case illustrate how simple and pertinent clinical observations and laboratory investigations is sufficient to allow a firm diagnosis to be made.

    Chronic diarrhoea in tropical countries may be due to a myriad of causes from infective to non-infective. This case report illustrates the challenges faced in the investigation of a middle-age Chinese gentleman who presented with chronic diarrhoea and weight loss. The diagnosis of type II enteropathy-associated T-cell lymphoma (EATL) was finally made. The diagnosis of EATL was least suspected as the condition is almost unheard of in this part of the world. The epidemiology, presentation, diagnosis, management and prognosis of this rare condition are discussed.

    PMID: 11045055
    The risk factors and modes of death following acute diarrhoeal illness in children admitted to University Hospital, Kuala Lumpur between 1982 and 1997 were studied retrospectively. Among 4,689 cases of acute gastroenteritis admitted, ten deaths were noted. The case mortality rate was 2.1/1000 admissions. All deaths were infants below one year, with eight females and two males. Acute renal failure and acute pulmonary oedema were common preceding events. Female sex, infants less than twelve months, the presence of hyper or hyponatraemia and moderate to severe dehydration on admission were risk factors for deaths.

    Zentralbl. Bakteriol., 1996 Mar;283(3):306-13.
    PMID: 8861868
    By means of the gentamicin HEp-2 cell invasion assay, it was demonstrated that 82% of the Campylobacters tested were cell-invasive, including 83% of isolates from bloody diarrhoea and 80% of isolates from watery diarrhoea. The large number of invasive strains from watery diarrhoea suggests the possible role of invasiveness in the production of watery diarrhoea. Whether this stage can progress further to more severe symptoms such as bloody diarrhoea remains to be elucidated. Whether this progression to bloody diarrhoea occurs as a result of toxin production is still debatable. In Vero cells, invasion was less efficient and intracellular multiplication was not observed.
