ABSTRACT
Cerebral cysticercosis is the most common worldwide parasitic infection of the central nervous system. Intraventricular involvement is apparent in 15% to 28.8% of cases with neural compartment infestation.' Although different forms of the disease (parenchymatous, subarachnoid, and mixed form ) have been treated successfully with chemotherapy, direct surgical excision of simple cystic lesions appears to be an adequate primary therapeutic strategy in the majority of intraventricular forms. In recent years, however, some authors have advocated the use of anthelmintic treatment in all cases of intraventricular cysts so that surgical procedures of the posterior fossa and their potential complications can be avoided. The strict definition for managing the spectrum of intraventricular infestation remains controversial. We present our experience in the treatment of a patient with primary isolated intraventricular cysticercosis.

Objective To compare discrepancy between genotype and pheotype of th e clinical isolates of Candida rugosa. Methods The fung us-specific universal prim ers derived from the internal transcribed spacer (ITS) region of fungal rDNA wer e used for amplification. Genomic DNA purified from the thirteen clinical isolat es of non-C. Albicans was amplified by PCR. The purified PCR product was cloned into pBluescript Ⅱ KS(+) T vector and sequenced by Sanger's dideoxy chain terminatio n composition method. The two isolates were evaluated against CHROM Candida medi um and API 20C AUX. Results The two isolates of Candida rugosa were evaluated as Candida tropicalis by CHROM Candida medium and API 20C AUX. Conclusio ns Discrep ancy between genotype and phenotype of the two clinical isolates of Candida ru gosa was confirmed.
ABSTRACT
Objective To develop a microtitration plate en zyme immunoassay to differentiate Candida albicans from Candida dubliniensis isolates using two specific probes s imultaneously.Methods The fun-gus-specific universal primers derived from the internal transcribed s pacer region of fungal rDNA were labeled with biotin,while the C.albicans or C.dubliniensis specific capture probes were coated on the microplates.Genomic DNA purified from the two species was amplified by PCR.The biotinylated p roducts were captured by the probes coated on the microplates.The A 405 value was finally determined by the c olorimetric assay.Results The two species of Candida could be detected specifically.Out of 108clinical isolates originally identified as C.albicans on the basis of germtube formation,two isolates were positive for C.dubliniensis and negative for C.albicans.The other106isolates were positive for C.albicans and negative for C.dubliniensis.Conclusions Two-specific-probe hybridization method is rapid and re liable for differentiating C.albicans from C.dubliniensis.
ABSTRACT
Objective To investigate the clinical features of the patients with encephalopathy caused by food borne parasites. Methods Questionnairing was carried out to collect and analyze clinical data of cerebral form of food borne parasitic diseases in the hospital during the past five years. Results Among 190 discharged medical histories, 115 cases were valid for investigation, the number of males was 73, females 42, with a ratio of 1.74∶1. Among these patients, 20.9% (24/115) had a history of eating raw meat. For discharge diagnosis, neurocysticercosis accounted for 92.2% (106/115),cerebral paragonimiasis 3.5% (4/115), sparganosis 2.6% (3/115), and angiostrongyliasis cantonensis and gnathostomiasis 0.9%(1/115) each. 13.9% (16/115) of the patients were hospitalized for three times or more. Conclusion More attention should be paid to food borne parasitic encephalopathy.
