Parasitic Infections Based on 320 Clinical Samples Submitted to Hanyang University, Korea (2004-2011)

We analyzed 320 clinical samples of parasitic infections submitted to the Department of Environmental Biology and Medical Parasitology, Hanyang University from January 2004 to June 2011. They consisted of 211 nematode infections, 64 trematode or cestode infections, 32 protozoan infections, and 13 infections with arthropods. The nematode infections included 67 cases of trichuriasis, 62 of anisakiasis (Anisakis sp. and Pseudoterranova decipiens), 40 of enterobiasis, and 24 of ascariasis, as well as other infections including strongyloidiasis, thelaziasis, loiasis, and hookworm infecions. Among the cestode or trematode infections, we observed 27 cases of diphyllobothriasis, 14 of sparganosis, 9 of clonorchiasis, and 5 of paragonimiasis together with a few cases of taeniasis saginata, cysticercosis cellulosae, hymenolepiasis, and echinostomiasis. The protozoan infections included 14 cases of malaria, 4 of cryptosporidiosis, and 3 of trichomoniasis, in addition to infections with Entamoeba histolytica, Entamoeba dispar, Entamoeba coli, Endolimax nana, Giardia lamblia, and Toxoplasma gondii. Among the arthropods, we detected 6 cases of Ixodes sp., 5 of Phthirus pubis, 1 of Sarcoptes scabiei, and 1 of fly larva. The results revealed that trichuriasis, anisakiasis, enterobiasis, and diphyllobothriasis were the most frequently found parasitosis among the clinical samples.

Enfermedades cutáneas producidas por algunos artrópodos en Chile / Cutaneous diseases caused by some arthropods in Chile

Existen muchos artrópodos que afectan al hombre y a animales. Algunos artrópodos sólo producen manifestaciones cutáneas o sistémicas, otros son vectores de diversas enfermedades. Las picaduras y mordeduras de artrópodos son un motivo de consulta muy frecuente en la práctica dermatológica diaria, la mayoría de diagnóstico y tratamiento fácil, sin complicaciones. A veces, sin embargo, las manifestaciones puden ser tan greves que producen la muerte. En ocaciones, por ejemplo, en pacientes que han viajado al extranjero, el diagnóstico de las lesiones puede ser difícil, y es necesario profundizar en los diagnósticos diferenciales. En este artículo revisamos las patologías cutáneas más frecuentes producidas por distintos artrópodos de las clases Insecta y Aracnida, tales como abejas, pulgas, moscas, chinches, vinchucas, arañas y escorpiones. Se describen con detalle las distintas manifestaciones cutáneas y sistémicas y se entregan algunos elementos teóricos en el tratamiento de éstas

Role of some medically important arthropods in home environment and childhood urticaria

Home environment does not only affect morbidity but also chronicity of certain disease of the reared children. Several medically important arthropods are of special concern, as well as domestic anima and pets. Fifty patients with popular urinary, compared to 50 normal controls, were tested with 5 types of mite antigens: acarus siro, dermatophagoides farinae, derratophagoides, pteronyssinus, clycophagus domesticus and tyrophaus putrescentiae. The skin reaction were recorded after 1/2 hours, 24 hours and 48 hours. This study revealed that popular urticaria is prevalent in children below 7 years. Both sexes were equally affected. Family history has no significant role in the disease. There was a significant relation between pets and the disease. Mites play an important role in the aetiology of popular urticaria. The most responsible mites are dermatophagiods farinae and yrophagus putrescentiae. Dermatophagoides pternoyssinus and glycophagus domesticus had no statistical significant relation to popular urticaria as tested by mite antigen skin reactions. However, there were actually more positive reaction in patients with popular utricaria than in the control groups. It is questionably advised that desensitization may be of real health for patients with popular urticaria which can be administered at an early phase of the disease. Also, environmerltal control of mites will be very helpful in suppressing and minimizing the attacks
