    Trichuris Dysentery Syndrome (TDS) is a severe persistent trichuriasis associated with heavy worm build-up in the colon that continues to be neglected and underestimated in endemic countries. Trichuriasis is most prevalent in children in tropical countries, and that increases the risk of TDS. We reported a series of four preschool children of both genders chronically having TDS over a period ranging from several months to years presenting with anaemia. The hemoglobin levels ranged from 4.6 to 9.1 g/dl on first admissions. Despite treatment, the cases were reported to have failure to thrive with persistent anaemia. It was concluded that TDS should be considered in endemic areas among children presenting with chronic bloody diarrhea and anaemia.

    BACKGROUND: The purpose of this study was to evaluate the immunoglobulin (Ig) G avidity of serological toxoplasmosis testing in patients with ocular inflammation and to determine the clinical manifestations of ocular toxoplasmosis.

    METHODS: A retrospective review of all patients presenting with ocular inflammation to the Hospital Universiti Sains Malaysia, Kelantan, Malaysia between 2005 and 2009 was undertaken. Visual acuity, clinical manifestations at presentation, toxoplasmosis antibody testing, and treatment records were analyzed.

    RESULTS: A total of 130 patients with ocular inflammation were reviewed retrospectively. The patients had a mean age of 38.41 (standard deviation 19.24, range 6-83) years. Seventy-one patients (54.6%) were found to be seropositive, of whom five (3.8%) were both IgG and IgM positive (suggestive of recently acquired ocular toxoplasmosis) while one (0.8%) showed IgG avidity ≤40% (suggestive of recently acquired ocular toxoplasmosis) and 65 patients (50.0%) showed IgG avidity >40% (suggestive of reactivation of toxoplasmosis infection). Chorioretinal scarring as an ocular manifestation was significantly more common in patients with seropositive toxoplasmosis (P = 0.036). Eighteen patients (13.8%) were diagnosed as having recent and/or active ocular toxoplasmosis based on clinical manifestations and serological testing.

    CONCLUSION: Ocular toxoplasmosis is a clinical diagnosis, but specific toxoplasmosis antibody testing helps to support the diagnosis and to differentiate between reactivation of infection and recently acquired ocular toxoplasmosis.

    Strongyloides stercoralis is an intestinal nematode infecting humans. The actual prevalence of infestation with this parasite in our setting is not well established. Thus, this study was conducted to determine the age, sex and co-morbid conditions among patients with S. stercoralis infestation as well as to study the common manifestations of strongyloidiasis in our patients. Records of patients with positive S. stercoralis larvae from January 2000 to December 2012 in Hospital Universiti Sains Malaysia, Kubang Kerian, Kelantan were reviewed. Ten patients were male and two were female. Their ages ranged from 19 to 78 years old. The majority (92%) of cases, presented with intestinal symptoms and 50% with moderate to severe anaemia. Thirty percent of cases had extraintestinal manifestations such as cough, sepsis and pleural effusion. Ninety-two percent of the patients had a comorbid illness. Most patients were immunocompromised, with underlying diabetes mellitus, retroviral disease, lymphoma and steroid therapy contributing to about 58% of cases. Only 58% were treated with anti-helminthic drugs. Strongyloidiasis is present in our local setting, though the prevalence could be underestimated.

    Ocular toxocariasis is prevalent among children. The symptoms and signs may mimic other ocular pathologies such as malignancies and other infectious diseases (such as toxoplasmosis and syphilis). We presented a case of progressive blurring of vision in a single eye of a 9-year-old boy. The presence of anti-toxocara antibody in serum samples helps to confirmation the diagnosis in our patient. Despite of treatment, the boy had lost his vision on the affected eye.

    Plasmodium knowlesi has been recently identified as the "fifth human malaria species" following the discovery in Malaysian Borneo of a large focus of this simian malaria parasite in humans. Even though it shares microscopic similarities with Plasmodium malariae, it may cause severe illness with risk of fatality. We describe a case of P. knowlesi infection causing multi-organ failure in a patient who was successfully managed due to early recognition of the infection. Clinicians in this region should be more aware of the infection as it is not as rare as previously thought. This case write up highlight the case of severe malaria infection which presented with multi organ involvement which is caused by P. knowlesi.

    Trichuris dysentery syndrome is caused by Trichuris trichiura which contributes to one of the most common helminthic infections in the world. It is associated with heavy colonic infection that manifests as mucoid diarrhoea, rectal bleeding, rectal prolapse, iron deficiency anaemia, and finger clubbing. Here, we report a case of trichuris dysentery syndrome complicated with severe chronic iron deficiency anaemia in a 4-year-old girl who required blood transfusion. The nematode was visualized on stool microscopic and colonoscopic examination. A longer duration of anti-helminthic treatment is required to achieve effective and better outcome.

    Strongyloidiasis is an infection caused by the intestinal nematode Strongyloides stercoralis. Infected healthy individuals are usually asymptomatic, however it is potentially fatal in immunocompromised hosts due to its capacity to cause an overwhelming hyperinfection. Strongyloidiasis could be missed during routine screening because of low and intermittent larval output in stool and variable manifestations of the symptoms. We present two cases of strongyloidiasis occurring in children with solid organ malignancies suspected to have the infection based on their clinical conditions and treatment history for cancer. Both patients were diagnosed by molecular and serological tests and were successfully treated. Thus, strongyloidiasis in patients undergoing intensive treatment for malignancies should be suspected, properly investigated and treated accordingly.

    Plasmodium knowlesi is a simian malaria parasite and is recently recognized as the fifth malaria parasite infecting humans. Manifestation of the infection may resemble other infection particularly dengue fever leading to inappropriate management and delay in treatment. We reported three cases of naturally acquired P. knowlesi in Hospital Universiti Sains Malaysia, Kubang Kerian, Kelantan, Malaysia. Clinical manifestations were quite similar in those cases. Microscopically, the diagnosis might be challenging. These cases were confirmed by polymerase chain reaction method which serves as a gold standard.

    Infections and mTalignancies are common causes of pleural effusion. Among infectious causes, hyperinfection syndrome of Strongyloides stercoralis may occur in immunosuppressive patient. A 62-year-old man, known case of Non-Hodgkin lymphoma (NHL) was presented with recurrent NHL stage IV and had undergone salvage chemotherapy. Patient subsequently developed pneumonia with bilateral pleural effusion and ascites. We reported rhabditiform larvae of S. stercoralis in pleural fluid of both lungs without infiltration by lymphoma cells. Stool for microscopic examination also revealed rhabditiform larvae of S. stercoralis. This patient was a known case of NHL receiving chemotherapy resulting in immunosuppression state. Although S. stercoralis infection is not very common compared to other parasitic infections, it is common in immunosuppressive patients and may present with hyperinfection. Therefore, awareness of this parasite should be kept in mind in immunosuppressive patients.

    Strongyloides stercoralis is a widespread, soil-transmitted helminth affecting humans. Autoinfection occurs in S. stercoralis infection and this leads to a continuous build-up of worm burden in human host. This may lead to hyperinfection syndrome which has the potential to cause serious life-threatening disease especially in immunocompromised and immunosuppressed patients. Thus, patient with underlying risk factors should be suspicious of having this infection as severe strongyloidiasis carries a high mortality rate if the diagnosis is delayed. Here, we report a case of S. stercoralis hyperinfection in a diabetic patient.

    Neonatal invasive Group A Streptococcus (GAS) infection is a rare occurrence nowadays. Prior maternal vaginal colonization is an important factor in early neonatal disease. We report a case of invasive and fatal infection in a neonate. At Day 1 of life, a term baby was found to be lethargic, with poor feeding, and later became unresponsive. Consequently, the baby was immediately brought to the Emergency Department of Hospital Universiti Sains Malaysia, Kubang Kerian, Kelantan via ambulance. Despite the active resuscitation efforts in the hospital, the baby died. An autopsy was carried out to determine the cause of death. The mother was noted to have puerperal pyrexia secondary to vaginal discharge. Her high vaginal swab culture was positive for GAS. GAS was also isolated from the intracardiac blood, pleural fluid, peritoneal fluid, and umbilical swab of the baby, giving evidence to the aetiology of the mortality. Vaginal colonization of GAS is an important factor for high morbidity and mortality for both mother and infant due to its invasiveness and virulence.

    A 36-year-old man with underlying chronic lymphocytic leukemia had left arm swelling for a duration of 3 months. Clinically, the affected arm was swollen, erythematous and tender. Epicoccum nigrum was isolated from the culture of the tissue that was obtained intraoperatively. He was treated and responded to voriconazole therapy. To the best of our knowledge, this is the first case of intramuscular abscess as a result of E. nigrum infection in an immunocompromised patient.

    This cross-sectional study determined the prevalence of cryptosporidiosis in HIV-infected patients using polymerase chain reaction (PCR). Stool specimens were collected from HIV infected patients who were admitted to Hospital Raja Perempuan Zainab II, Kota Bharu, Malaysia, for various indications from December 2004 to December 2005. A modified acid-fast stain was performed on the direct stool smears, then the stool specimens were further tested using nested PCR targeting the 18S rRNA gene of Cryptosporidium parvum, with a built-in internal control (IC). Out of 59 samples, 11 were positives. Nested PCR identified a total of nine samples (16%) compared to microscopy, which identified only three samples. All PCR negative results showed IC amplicons, suggesting that these samples were true negatives and were not due to inhibition of PCR. This study highlights the importance of molecular diagnosis in determining the true prevalence and epidemiology of C. parvum.

    We have developed an ELISA that employs monoclonal anti-Toxoplasma SAG1 (p30) as the capture antibody to detect T. gondii circulating antigens in patients' serum samples. Using serum spiked with Toxoplasma soluble and with SAG1 recombinant proteins, the detection limits were 31.25 ng/mL and 62.50 ng/mL, respectively. We obtained positive results in 28% (21/75) and 11% (23/206) of probable active and chronic toxoplasmosis serum samples, respectively. Western blot analysis on pooled antigen-positive serum samples showed antigenic bands of molecular weights 25 and 75 kDa from sera of probable active infection and five antigenic bands ranging in size from 26 to 33 kDa from chronic infection sera. This assay would be useful as an initial serum selection step in developing a Toxoplasma antigen detection test and for characterization studies.

    Amoebic serodiagnosis at Hospital Universiti Sains Malaysia (HUSM), Kelantan employs an indirect haemagglutination assay (IHA) which detects anti-Entamoeba histolytica antibodies in patients' serum samples. In an amoebiasis endemic area such as Kelantan, interpretation of a positive IHA result can be problematic due to the high background antibody levels. The TechLab E. histolytica II ELISA is a commercial kit for detection of specific Gal/GalNAc lectin antigen in stool samples, and has been reported to be able to detect the antigen in serum samples from patients with amoebic liver abscess (ALA). Thus in this study we investigated the usefulness of TechLab E. histolytica II ELISA for diagnosis of ALA by comparing it with IHA. This is a cross sectional study involving 58 suspected ALA patients who were admitted to the surgical ward, HUSM, Kelantan. The diagnosis of ALA was established based on clinical symptoms and signs, ultrasound and/or CT scan results. The serum specimens obtained from the patients were tested with IHA (Dade Behring Diagnostics, Marburg, Germany) and TechLab E. histolytica II ELISA (Techlab, Blacksburg, Virginia, USA) according to the manufacturers' instructions. Of the 58 patients, 72.4% (42) were positive by IHA and only 8.6% (5) were positive by the TechLab E. histolytica II ELISA. Agreement between the IHA and ELISA was poor (kappa value 0.019, p=0.691). There was also no correlation between ELISA results and IHA antibody titers. The TechLab E. histolytica II ELISA was not sensitive in detecting amoebic antigen in samples from ALA patients. In addition the results of the test did not correlate with the IHA anti-E. histolytica antibody titres. Therefore, the TechLab E. histolytica II ELISA was found not to be useful for serological diagnosis of ALA at HUSM.

    The human leucocyte antigen (HLA) has been documented to be involved in various disease susceptibilities or in resistance against certain diseases. An important element in susceptibility and resistance to disease is ethnic genetic constitution. Cognizant of this, the present study aimed at studying the prevalence of particular HLA class II in a normal healthy Malay population which may serve as a guide for further genetic and immunological studies related to the Malay Malaysian population. The study involved 40 normal healthy Malay persons in Kelantan. HLA typing was conducted on venous blood samples through a polymerase chain reaction-sequence specific primer method (low resolution Olerup SSP© HLA Typing Kits). The study found HLA DR12 and HLA DQ8 to be the most frequent HLA class II type. HLA DQ5 was significantly associated with female subjects.

    Enzyme-linked immunosorbent assays (ELISAs) were developed for the detection of IgG, IgG4 and IgE antibodies against Strongyloides stercoralis. A commercial ELISA (IVD Research, USA) was also used, and the sensitivities and specificities of the four assays were determined. Serum samples from 26 patients with S. stercoralis infection and 55 patients with other infections or no infection were analysed. Sensitivities of the IgG4 , IgG, IgE and IgG (IVD) assays were 76.9%, 84.6%, 7.7% and 84.6%, respectively, while the specificities were 92.7%, 81.8%, 100% and 83.6%, respectively. If filariasis samples were excluded, the specificities of the IgG4 -ELISA and both IgG-ELISAs increased to 100% and 98%, respectively. A significant positive correlation was observed between IgG- and IgG4 -ELISAs (r = 0.4828; P = 0.0125). IgG- and IgG- (IVD) ELISAs (r = 0.309) were positively correlated, but was not significant (P = 0.124). Meanwhile there was no correlation between IgG4 - and IgG- (IVD) ELISAs (r = 0.0042; P = 0.8294). Sera from brugian filariasis patients showed weak, positive correlation between the titres of antifilarial IgG4 and the optical densities of anti-Strongyloides IgG4 -ELISA (r = 0.4544, P = 0.0294). In conclusion, the detection of both anti-Strongyloides IgG4 and IgG antibodies could improve the serodiagnosis of human strongyloidiasis. Furthermore, patients from lymphatic filariasis endemic areas who are serologically diagnosed with strongyloidiasis should also be tested for filariasis.

    Pantoea infections are uncommon in humans. Most reports have involved adults or children after thorn injuries. There are only a few reports of systemic infections with Pantoea. This is the first report of the clinical picture of systemic Pantoea spp. infection in neonates as observed during an outbreak in a neonatal intensive care unit caused by infected parenteral nutrition solutions. Even though detected early, the infections had a fulminant course, causing septicemic shock and respiratory failure. Pulmonary disease was prominent and presented mainly as pulmonary hemorrhage and adult respiratory distress syndrome. The organism was sensitive to most antibiotics used in neonatal intensive care units, but the clinical response to antibiotic therapy was poor. The fatality rate was very high: 7 out of 8 infected infants succumbed to the infection (87.5%).
