52 cases of visceral parasitic infestation with eosinophilia were studied at Dong Nai Pediatric Hospital from April 2003 to July 2004. The most common symptoms were abdominal pain, headache, ecchymosis. In addition there were other manifestation such as at respiratory tract, joints, kidney. The symptoms had suggested visceral parasitic infection in children although there was no eosinophilia. Thus only serological examination was recommended

Human pulmonary dirofilariasis has been documented from many parts of the world, but not in Korea so far. We experienced a patient of pulmonary dirofilariasis who had visited a local clinic because of chest pain for 1 month. On chest radiograph, a coin lesion of 2 cm diameter and enlargement of the mediastinal lymph node were shown. An exploratory lung resection was done. Pathologically the lesion was a pulmonary dirofilariasis complicated with necrotic pneumonia, fibrosis, and infarction. At the center of the lesion, degenerated nematode sections with multilayered cuticle, thick musculature, and bilateral internal ridges on each side were found, which was identified to be Dirofilaria immitis. This is the first report of human pulmonary dirofilariasis in Korea.

Myiasis is most prevalent in Mexico, central and south America, tropical Africa, and the southwestern United States. Although dermal myiasis is rare in most of the United States, it is a disorder that may be seen in international travelers. In the United States, external myiasis is usually caused by the cattle botfly. We report here a case of ophthalmomyiasis involving the left upper eyelid of a child. We examined a six-year-old boy who presented to the Massachusetts Eye and Ear Infirmary (MEEI) in September 1998. He complained of persistent swelling of his left upper eyelid for the previous ten days. The edema and erythema were unresponsive to warm compresses and oral antibiotics. Ocular examination revealed a mild preseptal cellulitis of the left upper eyelid with a small draining fistula. On slit-lamp examination, we found one larva protruding intermittently from the fistula site. The larva was extracted with forceps, wrapped in a moist towel and sent in a jar to the parasitology laboratory. The specimen was identified as a Cuterebra larva by a parasitologist at the Harvard School of Public Health. One week later, the patient's eyelid edema and erythema had completely resolved.

Sparganosis is a kind of parasitic skin disease caused by sparganum, the plerocercoid larvae of the taper worm of the genus Spirometra. Sparganosis usually manifests as migrating or fixed subcutaneous nodules; therefore, it should be differentiated from lipoma, cysts, and cutaneous malignancies. Although the final diagnosis of sparganosis in humans depends on the identification of the worm in an infected tissue, suspicion for the presence of the parasite and careful history taking are important before making the diagnosis. However, it might be difficult for a clinician to suspect the existence of sparganosis because the incidence of this disease is extremely low. Therefore, an effective method for differentiating sparganosis from other skin disorders is needed. We suggest that ultrasonography could be an answer to this problem, on the basis of our experience of a case of cutaneous sparganosis in a 65-year-old woman showing very characteristic ultrasonographic findings.

BACKGROUND: Recently malaria infection became one of the most important parasitic diseases in Korea. After the re-emergence of malaria in a young soldier in 1993 near the De-Militarized Zone (DMZ), three to four thousand people have been infected per year in the last few years and the cases of infection have been increasing threefold each year. Microscopic examination of a thick blood smear is a conventional and confirmatory method for diagnosis. However, it requires labor-intensive procedures and its interpretation is quite subjective. Faster and more reliable methods are needed for the diagnosis of malaria. METHODS: We evaluated 155 patients who were diagnosed as malaria. We performed point-of-care rapid diagnostic methods recently introduced: two antibody detection tests manufactured by Korean companies and one antigen (Plasmodium lactate dehydrogenase, pLDH) detection test. The results were compared with those of microscopic examinations of thick blood smears. RESULTS: Sensitivities of two antibody detection assays and one antigen detection assay in acute attacks of malaria were 64.7%, 72.5%, and 96.1%; and, specificities were 88.5%, 89.4%, and 95.1%, respectively. Overall accuracy for all samples were 80.6%, 83.9%, and 95.5%, respectively. CONCLUSIONS: Antibody detection tests for malaria have limitations in sensitivity and accuracy to replace microscopic examination of blood film. Antigen tests detecting pLDH could replace conventional microscopic examinations of blood film, especially in emergency situations in cases that require prompt medication.

Sparganosis is a rare parasitic disease caused by the migrating plerocercoid larva of tapeworms in the genus Spirometra. The most frequent clinical manifestation of human sparganosis is a subcutaneous nodule resembling neoplastic disease. Since the disease is relatively uncommon, even in endemic areas, sparganosis is rarely considered in the differential diagnosis of skin lesions. We experienced a case of sparganosis mimicking a skin metastasis in a patient with metastatic stomach cancer and made the diagnosis after an excisional tissue biopsy.
