    Kimura's disease (KD) is an uncommon chronic inflammatory condition of unknown aetiology involving subcutaneous tissue, presenting as a tumor like lesion with a predilection for the head and neck region. Clinically it is often confused with parotid tumor with lymph node metastasis. It is difficult to diagnose before tissue biopsy. Fine needle aspiration cytology has only limited value. Unless the pathologists are aware of this entity, it might be misdiagnosed. Surgery, radiotherapy and steroid therapy have been tried but none is proved best and recurrence is common. Three cases of KD seen in our hospital and the problems encountered in them are presented.

    Angiostrongylus cantonensis is a bursate nematode parasite that causes eosinophilic meningitis (or meningoencephalitis) in humans in many parts of the world. The genomic data from A. cantonensis will form a useful resource for comparative genomic and chemogenomic studies to aid the development of diagnostics and therapeutics. We have sequenced, assembled and annotated the genome of A. cantonensis. The genome size is estimated to be ∼260 Mb, with 17,280 genomic scaffolds, 91X coverage, 81.45% for complete and 93.95% for partial score based on CEGMA analysis of genome completeness. The number of predicted genes of ≥300 bp was 17,482. A total of 7737 predicted protein-coding genes of ≥50 amino acids were identified in the assembled genome. Among the proteins of known function, kinases are the most abundant followed by transferases. The draft genome contains 34 excretory-secretory proteins (ES), a minimum of 44 Nematode Astacin (NAS) metalloproteases, 12 Homeobox (HOX) genes, and 30 neurotransmitters. The assembled genome size (260 Mb) is larger than those of Pristionchus pacificus, Caenorhabditis elegans, Necator americanus, Caenorhabditis briggsae, Trichinella spiralis, Brugia malayi and Loa loa, but smaller than Haemonchus contortus and Ascaris suum. The repeat content (25%) is similar to H. contortus. The GC content (41.17%) is lower compared to P. pacificus (42.7%) and H. contortus (43.1%) but higher compared to C. briggsae (37.69%), A. suum (37.9%) and N. americanus (40.2%) while the scaffold N50 is 42,191. This draft genome will facilitate the understanding of many unresolved issues on the parasite and the disorder it causes.

    The intradermal test using as antigen a 1 per cent saline extract of Dirofilaria immitis powder was performed in Singapore on 69 persons with eosinophilic lung, 32 with mild eosinophilia, 49 with filariasis, 75 normal Asians, and 66 normal Britishers. The test was positive in 100 per cent of the cases of eosinophilic lung, 73.5 per cent of the filariasis group, 59.4 per cent of cases of mild eosinophilia, 53.3 per cent of normal Asians, and 4.5 per cent of the Britishers. The filarial complement fixation test using a 1 per cent alcoholic extract of the same antigen gave a positive rate of 100 per cent in the eosinophilic lung group, whereas only 24.5 per cent of the filariasis patients gave a positive reaction. Skin sensitivity to D. immitis antigen persisted in the cases of eosinophilic lung even when the previously positive serologic reactions had become negative following treatment with diethylcarbamazine. Therefore, the intradermal test cannot be useful in the diagnosis of either filariasis or eosinophilic lung in Singapore. In view of the skin sensitivity to a filarial antigen demonstrated in patients suffering from eosinophilic lung, the etiologic possibility of an infection by a species of filarial worm found normally in nonhuman hosts is discussed.

    Tropical pulmonary eosinophilia (TPE) is considered to be a variant of human filarial infection. The pulmonary manifestations of TPE have been well described. Extra-pulmonary features of the disease, although not commonly seen, have been reported previously. A 9-year-old Malay girl with a history of recurrent cough and wheezing was admitted because of cardiac failure. Physical examination revealed a very sick girl with tachypnoea, central cyanosis, finger clubbing, elevated jugular venous pulse, generalized crackles and rhonchi in the chest, a loud second heart sound and hepatosplenomegaly. A chest radiograph showed cardiomegaly and right pleural effusion. Laboratory investigations revealed hypochromic, microcytic anaemia with persistent blood eosinophilia (absolute eosinophil counts varied from 1.9 to 5.5 x 10(9)/1). The ELISA test for antifilarial IgG antibodies was strongly positive. She responded promptly to treatment with diethylcarbamazine. In summary, this is a patient with TPE who presented with cor pulmonale, probably due to late-stage interstitial pulmonary fibrosis. In order to prevent the long term morbidity of cardiorespiratory disability, the early signs of TPE should be recognized and the infection treated.

    A 54-year-old Chinese man presented with ascites for 2 weeks. He had a preceding 2-year history of intermittent dysphagia, lethargy and general malaise. Blood investigations revealed leucocytosis with eosinophilia of 26.5%, whereas paracentesis showed turbid fluid with high protein content (45 g/L) and a high white blood cell count of 5580/µL, predominantly eosinophils (90%). An incidental assay of vitamin D showed a very low level of 13.5 ng/mL. No other cause of ascites was found. Gastroscopy was normal except for duodenitis. However, biopsies from lower oesophagus confirmed the presence of eosinophilic infiltration. Following vitamin D replacement, the patient experienced marked improvement in symptoms of dysphagia within 2 weeks and no recurrence of ascites after 3 months. The reason for the patient's vitamin D deficiency remains unclear. The marked improvement in the patient's health indicates a causative role of vitamin D deficiency in causing eosinophilic esophagogastroenteritis and associated eosinophilic ascites.

    We report a case of diffuse unilateral subacute neuroretinitis in a young boy with no clinical visualization of nematode. The diagnosis was made based on clinical findings and detection of Toxocara immunoglobulin G by Western blot test. An 11-year-old Malay boy presented with progressive blurring of vision in the left eye for a duration of 1 year. It was associated with intermittent floaters. Visual acuity in the left eye was 6/45 and improved to 6/24 with pinhole. There was positive relative afferent pupillary defect, impaired color vision, and presence of red desaturation in the left eye. There were occasional cells in the anterior chamber with no conjunctiva injection. Posterior segment examination revealed mild-to-moderate vitritis and generalized pigmentary changes of the retina with attenuated vessels. The optic disk was slightly hyperemic with mild edema. There was presence of multiple, focal, gray-white subretinal lesions at the inferior part of the retina. Full blood picture results showed eosinophilia with detection of Toxocara immunoglobulin G by Western blot test. Investigations for other infective causes and connective tissue diseases were negative. The diagnosis of diffuse unilateral subacute neuroretinitis secondary to Toxocara was made based on clinical findings and laboratory results. He was treated with oral albendazole 400 mg daily for 5 days and oral prednisolone 1 mg/kg with tapering doses over 6 weeks. At 1 month follow-up, the inflammation had reduced, and multiple, focal, gray-white subretinal lesions were resolved; however there was no improvement of vision.

    Three patients presenting with parotid, submandibular, and/or lymph node masses were subjected to fine-needle aspiration cytology. Smears showed dissociated and clustered endothelial cells, eosinophils, lymphocytes, and Warthin Finkeldey giant cells. In two cases a diagnosis of Kimura's disease was suggested from the FNA cytologic smears. In the third case the presence of mononucleate cells with prominent nucleoli led to a suspicion of Hodgkin's disease. Excision biopsy and histopathologic study established a diagnosis of Kimura's disease in all three cases.

    Brugia malayi and Wuchereria bancrofti infections cause lymphatic filariasis in Malaysia. About 2.5 million people live in endemic areas of filariasis, of whom 5% have microfilaraemia and probably twice as many are infected. There is a wide clinical spectrum of response to the infection. While some have asymptomatic microfilaraemia, others have episodic attacks of fever, lymphadenitis, retrograde lymphangitis and lymphoedema. Elephantiasis is a late complication. Tropical pulmonary eosinophilia and other forms of occult filariasis are due to hyper allergic reactions to microfilarial antigens. Parasitological and serological tests aid in confirming the clinical diagnosis. The drug of choice is diethylcarbamazine citrate.

    Background/Aims: The epidemiology of eosinophilic gastroenteritis remains unclear. We aim to determine the prevalence of eosinophilic gastroenteritis in patients with lower abdominal symptoms.

    Methods: In a prospective study, colonoscopy was performed on 2,469 consecutive patients. Biopsies were taken from the terminal ileum and ascending, transverse, descending and sigmoid colon in all patients.

    Results: Sixty-four of the 2,469 patients (2.6%) had eosinophilic gastroenteritis. Only five of the 64 patients (7.8%) with eosinophilic gastroenteritis had endoscopic mucosal abnormalities during colonoscopy. Six of these 64 patients (9.4%) had severe disease at presentation, and seven of these 64 patients (10.9%) required systemic steroid treatment. An elevated absolute peripheral eosinophil count was independently associated with severe disease at presentation (4/6 [66.7%] vs 3/58 [5.2%], p=0.005; odds ratio [OR], 25.320; 95% confidence interval [CI], 2.628 to 243.910), and severe disease at the time of presentation was independently associated with the use of systemic steroid treatment (6/7 [85.7%] vs 0/57 [0%], p=0.008; OR, 18.021; 95% CI, 2.163 to 150.152).

    Conclusions: The prevalence of eosinophilic gastroenteritis is common, and patients usually present normal-appearing mucosa on colonoscopy. Those with severe disease at presentation usually have a raised absolute peripheral eosinophil count and should be commenced on systemic steroids as an initial therapy.

    Kimura's disease is a chronic inflammatory disorder of unknown etiology commonly seen among orientals and characterized histologically by lymphatic follicles, vascular proliferation, and marked eosinophilic infiltration. It has a predilection for the head and neck region. The lesion is benign but can be mistaken to be a malignant lesion.

    Developing and adult worms of the human lymphatic filarial parasites (Wuchereria bancrofti,
    Brugia malayi, and Brugia timori) are located mainly in the lymphatic system and occasionally in aberrant sites like subcutaneous and conjunctival cysts. Lymphatic
    pathology ranging from dilatation of lymphatic channels and lymphangiectasia are detected on ultrasonography in apparently healthy, amicrofilaraemic, but filarial antigen positive individuals in endemic areas. Microfilariae are distributed in various organs and may be associated with immune mediated pathology at these sites; tropical pulmonary eosinophilia is characterized by intense immune mediated destruction of microfilariae in the lung parenchyma. In the spleen and other sites, nodular granulomatous lesions can occur where microfilariae are trapped and destroyed. The finding of Wolbachia endosymbionts in all stages of lymphatic filarial parasites has provided new insight on the adverse reactions
    associated with anti-filarial chemotherapy. Inflammatory molecules mainly lipopolysaccharide (LPS)-like molecules released from endosymbionts on death of the
    parasites are largely responsible for the adverse reactions encountered during anti-filarial chemotherapy. Prenatal tolerance or sensitization to parasite derived molecules can immune-modulate and contribute to both pathology and susceptibility/resistance to infection. Pathological responses thus depend not only on exposure to filarial antigens/infection, but also on host-parasiteendosymbiont factors and to intervention with antifilarial treatment. Treatment induced or host mediated death of parasites are associated with various grades of inflammatory response, in which eosinophils and LPS from endosymbionts play prominent roles, leading to death of the parasite, granulomatous formation, organization and fibrosis. The non-human primate (Presbytis spp.) model of
    Brugia malayi developed for the tertiary screening of anti-filarial compounds has provided unique opportunities for the longitudinal study of the pathology associated with lymphatic filariasis. The pathology in this non-human primate model closely follows that seen in
    human lymphatic filarial infections and correlates with clinical evidence of lymphatic pathology as detected with ultrasonography. These studies also show that successful treatment as detected by loss of motility and calcification of worms on ultrasonography is associated with reversal of early dilatations of lymphatic channels.

    The antiepileptic drug phenytoin can cause cutaneous adverse reactions, ranging from maculopapular exanthema to severe cutaneous adverse reactions, which include drug reactions with eosinophilia and systemic symptoms, Stevens-Johnson syndrome, and toxic epidermal necrolysis. The pharmacogenomic basis of phenytoin-related severe cutaneous adverse reactions remains unknown.

    Lymphatic filariasis is endemic in Asia. The infections persist as a major cause of clinical morbidity and a significant impediment to socioeconomic development. Its prevalence is increasing world wide, largely because of rapid unplanned urbanization in many endemic areas. It is estimated that at least 120 million people are infected. In our study on foreign workers, a total of 241 day time blood samples were collected. The countries represented were Bangladesh (134), Indonesia (103), Pakistan (3) and Myanmar(1). The tests conducted on blood samples were thick blood film for microfilaria and thin blood film for malaria and quantitation of eosinophiles using the Giemsa stain. Out of the 241 blood samples tested, one was positive for Wuchereria bancrofti and one other was positive for malaria (Plasmodium falciparum) each from Bangladesh and Indonesia respectively. As for the blood eosinophiles, 39 (16.18%) blood samples showed high eosinophilia. Fifteen (6.22%) were from Banglandesh and 24 (9.96%) were from Indonesia. The Bangladeshi male who was positive for Witcherrria bamuofti also showed eosinophilia of 22%. We believe that some of these cases with high eosinophilia, may be positive for microfilaria. We may have missed some cases because of the methodology we chose. Lymphatic filariasis is endemic in Bangladesh and Indonesia. In Malaysia W. brancrofti, especially in the cities have been eliminated. However their vectors for the transmission of W. bancrofti is rampant in the cities. With the influx of immigrants with W. bancrofti and in relation to their occupational nature, W. bancrofti may eventually be introduced into the community and change the whole facet of the disease in Malaysia.

    This section only examines the clinical findings and some blood chemistly in these workers. A total of 222 men and 28 women were studied. Their ages ranged from 12 to 57 years, the mean being 30.1 (±7.4). Generally most of the physical examination was normal and no external features of infectious diseases were seen. The mean systolic and diastolic blood pressure was 120 (±13) and 76(±8.7) nun Hg respectively. About 8.4% of the population had elevated blood pressure of 140/90 mmHg or greater. About 12.4% of these man and women were underweight (Body mass index (EMI) less than 19 kg/m2) while 11.2% were either overweight or obese (BMI>25) with the mean being 21.8 (±2.7). Only 3 had BMI greater than 30. Three subjects had a lnitral regurgitation murmur thought to be due to mitral valve prolapse. Four others had tinea cruris, six had insignificant axillary lymph-nodes, five had cervical lymph-nodes of which one was due to carcinoma of the tonsil 30 with shotty inguinal lymph-nodes which was thought to of no pathological significance. Four subjects had crepitations and five had rhonchi in their lungs. A full blood count revealed that 16.65% of the man and 32.1°/o of the women had haemoglobin levels of less than 14gm/dl and 12gm/dl respectively. The most striking abnormality was the high prevalence of eosinophilia. 37% of the subjects had eosinophilia counts of greater than 450/dl. About 19.4% of this study population had fasting blood glucose of greater than 6mmol/l but only 1.3% with fasting blood glucose of greater than 7.8 mmo/l. About 22% of the urine examined revealed pro- teinuria but were otherwise unremarkable for the other parameters. This group of foreign workers was made up of a presumably fairly healthy young population. Attempts to look for infectious disease on physical examination, not surprisingly did not reveal any remarkable findings. It could be that the majority of these subjects already had a examination prior to coming into the country and another one soon after arrival. However an indirect measurement of infectious diseases via the eosinophilic count revealed a high prevalence of parasitic infestations. Attempts to examine the end results of social hardship, be it intrinsic before or appearing after arrival indirectly shoved some degree of suffering. There was a fairly high prevalence of anaemia, especially amongst the women. The body mass index also revealed this population to be generally less obese than other populations. The value of medical check-ups has been debated, especially if it were done as a pre-employment procedure. This pilot study has shown that it is not cost-effective to do physical examination or blood chem- istry and urine analysis in hying to identify infectious diseases in the migrant workers. In the light of the paucity of clinical findings in this pilot study, it would be prudent to review the strategy for examining the health status of migrant workers. Perhaps the physical examination can be dispensed with, and blood andurine analysis beveryfocused and directedin order to maximise the cost- effectiveness of this programme. Certainly the high prevalence of eosinophilia needs further evalua- tion.

    The aim of this study was to determine the prevalence and extent of diseases present among migrant workers. A total of 809 migrant workers were examined. The mean BMI (Body Mass Index) was 22.3 kg/m2. Only 4.9% of the respondents had blood pressure greater than 140/90 mmHg. Generally the migrant workers examined were healthy, except for subjects with abnormal eosinophilia coutns, which may indicate occult parasitic infestation. Non-communicable disease in particular hypertension and diabetes mellitus are not major problems among migrant workers. Perhaps the target to aim at are the illegal migrant workers where more illness could be detected.

    We would like to report a case of a 29-year-old male patient who presented with multiple lymphadenopathy and vague symptoms of low grade fever, cough, weight loss, rashes, vomiting, dry eyes and dry mouth. Physical examination revealed submandibular lymphadenopathy, vasculitic rashes over both lower limbs, and parotid gland enlargement. Blood investigations showed mild anemia with leukocytosis, predominantly eosinophilia and high erythrocyte sedimentation rate and C-reactive protein. Computed tomography of the neck, thorax and abdomen showed bilateral submandibular, submental adenopathy, mediastinal and para-aortic lymphadenopathy with generalized reticulonodular densities in both lower lobes. There were hepatomegaly and bilateral enlarged kidneys with renal cyst. Histopathological examination from the cervical lymph node later revealed non-caseating granuloma, consistent of sarcoidosis. Patient responded well to prednisolone 50 mg daily with subsequent reduction in the size of cervical lymphadenopathy and parotid swelling.

    The association of mast cells with typical lesions of Kimura's disease was investigated by quantitative methods after immunohistochemical staining for Factor VIII-related antigen and counterstaining with toluidine blue. Formalin-fixed, paraffin-embedded, tissue sections from 9 confirmed cases of Kimura's disease were examined after staining to estimate mast cell and blood vessel densities by counting 100 random fields under oil immersion. There was a statistically significant increase of both mast cells and blood vessels in Kimura's disease (p<0.01) compared with normal skin and reactive lymph node controls. However, as far as the individual Kimura's disease lesion is concerned, there was generally no correlation between areas with mast cell increase and the degree of vascularity. Moreover, when lesions of less than 1 year's duration were compared with older lesions, there appeared to be a relative decrease in mast cells and a concomitant increase in vascularity in the latter. These results confirmed that mast cells are associated with Kimura's disease, and suggest that they may be involved in its early pathogenesis, although its possible role in angiogenesis may not be direct.
