Abstract
A 37-year-old woman presented to our hospital with mild abdominal pain experienced for 2 months and hepatic nodules in segments 3 and 8. Peripheral blood eosinophilia was observed, and toxocariasis was serologically diagnosed. Seventeen days after the first imaging evaluation, a new lesion was found in segment 9 of the right lung, which was contiguous through the diaphragm to the hepatic nodule in segment 8. After treatment with albendazole, the liver and lung nodules disappeared. We suspect that larvae had directly invaded the lung from the liver, through the diaphragm.

Abstract
Hepatic toxocariasis is visceral larva migrans caused by Toxocara. We report a case of hepatic toxocariasis detected incidentally during a health checkup. The patient had elevated levels of eosinophils, total IgE, and anti-Toxocara IgG antibodies. On contrast-enhanced computed tomography (CT) imaging he had a single, 2.16 cm, oval, ill-defined, low-attenuation hepatic nodule which was best appreciated during the portal venous phase of the scan. Clinicians should consider hepatic toxocariasis as a possible diagnosis in any individual who presents with eosinophilia of unknown etiology and an ill-defined hepatic lesion on CT imaging.

Abstract
The purpose of this study is to determine the relevance of the hygiene hypothesis; that is to determine if worm infestation has a protective role against the development of allergic rhinitis. A prospective case controlled study was conducted. Specific IgG levels to Toxocara were studied in 85 patients confirmed to have allergic rhinitis and were compared to levels in another 85 controls, with no form of allergy. The IgG assay was done using ELISA technique. There was a higher incidence of positive specific IgG to Toxocara in the controls as compared to allergic patients. The values were statistically significant [Chi square test (p=0.002)]. This negative association between worm infestation and allergic rhinitis suggests that a previous worm infestation could protect against the development of allergic rhinitis.

Abstract
INTRODUCTION Toxocariasis is a zoonosis which is in Serbia characterized with a very high infection rate of dogs and excessive contamination of the soil with the eggs of Toxocara canis, the agent of the disease. Toxocara-induced infections have in recent years been established in a few hundreds of children, but toxocariasis has rather rarely been diagnosed in adults. CASE REPORT We reported toxocariasis (visceral larva migrans) in an adult, manifested by migratory pulmonary infiltrates and positive serological test finding to Toxocara. CONCLUSION Human toxocariasis is a rare disease in adults, therefore it should be considered in adult patients presented with eosinophilia and migratory pulmonary infiltrates.

Abstract
We report the case of a 62-year-old man who developed eosinophilic pneumonia due to visceral larva migrans (VLM) that was possibly caused by Ascaris suum. The patient, a resident of the middle Kyushu area who was found of eating raw porcine liver, complained of dry cough without dyspnea. The chest radiography showed a migration of infiltrative shadow. Transbronchial lung biopsy of the right middle lobe revealed massive infiltration of eosinophils. The multi-dot enzyme-linked immunosorbent assay (ELISA) and microtiter plate ELISA showed positive results for A. suum; therefore, the patient was diagnosed with VLM caused by A. suum. The patient was administered albendazole (600 mg/day) for 28 days; he recovered successfully with no adverse effects except mild liver dysfunction. Several cases of VLM caused by A. suum have been reported in Japan, with a majority of the cases being reported in Kyushu. Careful history taking of the patient's area of residence and dietary habit is essential for the diagnosis of this parasitic disease with underestimated prevalence.

Abstract
Toxocariasis is one of the causes of eosinophilia in peripheral blood and provokes eosinophilic infiltration in internal organs. In Israel, the number of cases of toxocariasis is very low, 3 cases annually, according to the records at the Ministry of Health. Many cases of eosinophilia might be misdiagnosed as hypereosinophilia syndrome (HES), if serological testing for Toxocara is not conducted, leading to inappropriate treatment. The test is for specific serum IgG antibody of Toxocara canis antigen measured by enzyme-linked immunosorbent assay (ELISA). The authors present a 4 year old girl with hypereosinophilia of 40,000 cell/microl, without involvement of target organs. The authors found that toxocara was the cause of hypereosinophilia. After appropriate treatment the number of eosinophils decreases, presenting a measurement of the parasite activity.

Abstract
A 21-year-old woman admitted for a low-grade fever, dry cough, polyarthralgia, and general fatigue was found to have elevateal accustomed to eating raw meat and cattle liver peripheral blood eosinophil counts and serum IgE. Chest X-ray imaging and computed tomography (CT) showed multiple small nodules in both lung fields. A multiple dot-ELISA assay of her serum showed that she had visceral larva migrans caused by Ascaris suum or Toxocara canis. Following treatment with albendazole, she developed myelopathy and was again admitted. A cerebrospinal fluid examination showed increased eosionophils and significant antibody elevation against T. canis. Her disease was considered to have entered the central nervous system, one of the target organs of visceral larva migrans. She was successfully treated with dietylcarbamazine and has shown no reccurrence. This case showed the different manifestations of visceral larva migrans and the rising incidence of this disease in Japan raises concerns about associated of diet.

Abstract
An unusual presentation of visceral larva migrans observed in a patient is reported. A 5-year-old boy suffering fever, abdominal pain, tenderness, and rigidity in the right lower and upper quadrant of the abdomen was operated on, with the false diagnosis of acute abdomen, and exploratory surgery was carried out. The pathological examination of the liver biopsy revealed eosinophil-rich necrotizing granulomatous inflammation with Toxocara spp larva. The diagnosis was also confirmed by serologic results. Clinicians should remember that toxocaral visceral larva migrans may rarely mimic an acute abdomen and cause unnecessary operations.

Abstract
A growing body of clinical cases suggests that a kind of nematode larva, type X larva of the suborder Spirurina that inhabits firefly squids (Watasenia scintillans, or 'Hotaru-ika' in Japanese), can cause acute ileus in humans. However, the larva itself has rarely been found in the wall of the obstructed intestine. We describe here a case of acute ileus, in which a type X spirurina larva was found histologically. A 60-year-old Japanese man suffered from acute abdomen, and an emergency laparotomy revealed a marked stenosis of the ileum. Histological study of the surgically resected ileum showed severe eosinophilic enteritis and a nematode larva. The morphological features of this larva were identical to those of the type X spirurina larva. Interestingly, the larva that was found existed within a small blood vessel, suggesting that the larva migrans of type X spirurina can take place via vasculature. The patient in the present case did not recall ingesting raw squids prior to the onset of his disease. Hence, this indicates that even if the ingestion of raw firefly squids is uncertain, spirurina infection should be included in the differential diagnosis of acute ileus or eosinophilic enteritis.

Abstract
A 35-year-old man noticed a tingling sensation and subsequent slight weakness in the distal part of the left lower extremities, which extended to the left thigh over the following 8 months, when he developed a urinary disturbance. He was admitted to a local hospital and diagnosed as having myelitis, because of the presence of a gadolinium (Gd)-enhanced lesion in the lumbar spinal cord corresponding to the tenth thoracic vertebra (Th10) level. The symptoms disappeared along with some residual sensory disturbance following intravenous administration of 1 g of methylprednisolone (IVMP) for 3 days. However, 4 months later, the patient gradually developed gait disturbance, dysuria, impotence, and fecal incontinence, and was admitted to our hospital in May 2001. A neurological examination revealed the presence of myeloradiculopathy causing a slight weakness in the left hamstring muscles, with positive Babinski and Lasegue signs on the same side. In addition, deep tendon reflexes were absent in the 4 extremities and vibration sense was moderately decreased in the lower extremities, though the results of electrophysiological tests of motor and sensory nerves were normal. A magnetic resonance imaging (MRI) study showed a Gd-enhanced lesion in the spinal cord at the Th8-9 vertebrae level, which was 1 to 2 vertebrae above the initially detected lesion. A lumbar puncture yielded cerebrospinal fluid (CSF) containing mononuclear cells at 7/mm3 that were comprised of an increasd number of CD4+CD25+ activated helper T cells; however, no myelin basic protein or oligoclonal IgG band was present. Serological examinations were negative for the presence of collagen/vascular disorders as well as viral infection due to CMV, EBV, HSV, VZV, and HTLV-1, however, positive for specific antibodies against Ascaris suum in both serum and the CSF, confirming the diagnosis of chronic myeloradiculitis due to visceral larva migrans. The patient was first treated with a single course of a daily 600-mg dose of oral albendazole for 4 weeks, which was resulted in restoration of muscle weakness, as well as disappearance of the Lasègue sign. However, in contrast to the clinical improvement, the CSF sample obtained immediately after completing the treatment showed a worsening trend, as the CSF cell count had increased with a manifestation of marked eosinophilia and CD4+CD25+ cells were also increased. Thereafter, 3-day IVMP treatment was performed twice in cojunction with 3 courses of oral albendazole therapy for the subsequent 4 months, which resulted in normalization of all laboratory measurements concerning the CSF along with a decrement trend in serum and CSF antibody titers specific to Ascaris suum. Our results suggest that neurological involvement due to visceral larva migrans can be efficaciously treated with not only helminthic drugs but also intravenous corticosteroids.

Abstract
The aim of the study was to monitor the clinical course of T. canis infection in children with particular consideration of the estimation of infected children's immune system. The study comprised 52 children, aged 3 to 18 years, diagnosed and treated at the I Department of Paediatrics and Gastroenterology, Institute Polish Mother Health Centre, in whom infection with Toxocara canis larva was confirmed with serologic test. The control group included 38 children, aged 3 to 16 years in whom no infection with this parasite was detected in serologic test. In the investigated children subjective and physical examinations were performed, clinical symptoms, changes in organs, haematological, biochemical investigations and selected parameters of humoral and cellular immunity were analysed. In children with toxocarosis most frequently not localized abdominal pain, subfebrile body temperature and generalized lymphadenitis were observed. Significantly higher percentage of eosinophil cells and immunoglobulin E serum concentration with decreased percentage of lymphocytes CD3+, CD4+ and CD4/CD8 ratio were found in the investigated children. Toxocarosis diagnosis is difficult because its clinical symptoms are differentiated and not characteristic, what requires broadening of differential diagnosis concerning numerous entities.

Abstract
A 26-year-old man who was diagnosed with myocarditis presented eosinophilia after having eaten raw meat several times before the admission. Since the antibody titer against Toxocara canis was high, we diagnosed that he had visceral larva migrans due to Toxocara canis associated with myocarditis and eosinophilia. He was then treated with oral albendazole and prednisolone for 4 weeks and eosinophil count and hepatic enzymes were normalized along with the decrease in the antibody titer. We consider that his myocarditis was probably caused by direct larval migration and/ or by hypersensitivity reaction, for which combined therapy with albendazole and prednisolone was effective.

Abstract
A 32-year-old man presented with the chief complaint of severe cough. Examination of peripheral blood showed a marked increase in eosinophils. Chest CT demonstrated multiple ground glass opacities in both lungs. Bronchoalveolar lavage showed abundant eosinophils. Abdominal CT demonstrated multiple low attenuation areas in the liver. Liver biopsy with ultrasonography revealed severe eosinophil infiltrations around the portal veins. Serologically, a multi-dot enzyme linked immunosorbent assay (DOT-ELISA) and ELISA inhibition test using microtiter plates were positive for Ascaris suum. Thus, visceral larva migrans due to Ascaris suum was diagnosed. Outbreaks of this disease in Japan have previously been confined to the Kyushu area. The present case which occurred outside that area, illustrates the importance of constant attention to the epidemiology of this disease.

Abstract
Ocular toxocariasis in adults may cause serious diagnostic and therapeutic problems. We describe a case of a 54-year-old farmer who developed peripheral granuloma with dense connective tissue strands joined to the disc. The diagnosis was confirmed by high ELISA titers in the serum and vitreous body. We performed pars plana vitrectomy with epiretinal membrane removal and laser photocoagulation of the inferior retina, obtaining improvement of visual acuity. After a few weeks the patient returned with central retinal detachment and macular hole. After the second vitrectomy with use of silicon oil we obtained reattachment of the retina but without functional improvement.

Abstract
A 38-year-old woman presented with worsening cough, blood eosinophilia, and pulmonary infiltrates. Bronchoalveolar lavage showed 96.4% eosinophils. The diagnosis of visceral larva migrans (VLM) was made based on the positive results in enzyme-linked immunosorbent assay for Toxocara canis together with clinical symptoms and laboratory data. Pulmonary infiltrates due to VLM generally manifest as a transient form of Löffler's syndrome or simple eosinophilic pneumonia mainly in children. Here we report an adult case of VLM, with pulmonary infiltrates pathologically proven to be eosinophilic pneumonia, which persisted for 7 weeks before anthelmintic treatment with albendazole and manifested as chronic eosinophilic pneumonia.

Abstract
A 68-yr-old man presented with fever, cough, and appetite loss. On admission, clinical examination revealed pleural effusion (with eosinophils accounting for 25% of the cellular component), eosinophilia, and mildly elevated liver enzymes. A diagnosis of toxocariasis was reached on the basis of a positive enzyme-linked immunosorbent assay for Toxocara canis, and the efficacy of steroid and tiabendazole. Typical thoracic involvement of toxocariasis causes cough, wheezing, transient infiltration shadows on the radiographs, and other symptoms of Löffler's syndrome. The infiltration shadows reflect the migration of the larvae through the lung, which involves their breaking through the alveolar walls. We report a rare case of toxocariasis with thoracic and pleural involvement without transient pulmonary infiltrates.

Abstract
Imaging findings of hepatic lesions of visceral larva migrans are reported. A 44-year-old man presented with chills, eruptions, marked leukocytosis (31,400/microlitter), and eosinophilia (eosinophil, 72%). Multiple liver nodules were detected as low-density lesions on computed tomography (CT). They were visualized as high signal intensity lesions on T2-weighted, and as low signal intensity lesions on T1-weighted magnetic resonance imaging (MRI). The patient was diagnosed as having visceral larva migrans due to Toxocara canis, by Toxocara immnoserological test. After antihelmintic therapy, multiple liver nodules disappeared on CT. We consider that the differential diagnosis of multiple liver nodules should include visceral larva migrans.
