Is itraconazole the treatment of choice in Microsporum canis tinea capitis?

Mycotic scalp infection caused by Microsporum canis is the most dominant cause of tinea capitis in Greece. Griseofulvin has been the gold standard for the treatment of tinea capitis, but it is unavailable in our country. In this study, we evaluated 111 children with M. canis tinea capitis that were treated with itraconazole. Eighty-one of them were treated with itraconazole capsule pulse therapy (group A) and 30 (group B) were treated with oral suspension administered in continuous regimen. Twenty-one patients, all from group A, were lost to follow-up, probably due to the length of this regimen. In all patients that made up the study protocol, complete cure was achieved within seven pulses for group A and 12 weeks for group B. No significant side effects to lead to the cessation of therapy were recorded. Laboratory investigations were performed in 32 randomly chosen patients and were within normal ranges. The response to therapy did not appear to depend upon the formulation administered (capsules versus suspension). Using the pulse regimen, we also believe that it is necessary to individualize the number of pulses administered according to the clinical response. In conclusion, itraconazole proved safe and effective in our study, providing an ideal alternative to griseofulvin.

Neisseria gonorrhoeae in Athens, Greece. Epidemiologic classification and antimicrobial susceptibility patterns of strains isolated between 1986 and 1989.

The incidence of gonorrhoea cases diagnosed in a major venereal hospital of Athens, Greece, was markedly reduced between 1986 and 1989. All 182 gonococcal isolates found during this period were epidemiologically classified into Sero-/Auxo-/Plasmid content (S/A/Pc) types. Susceptibility to six antimicrobials was also determined. Penicillinase-producing Neisseria gonorrhoeae (PPNG) strains were isolated in an increased frequency of 7.7% and a striking shift in their distribution into S/A/Pc types was noted from previous years. The isolates exhibited wide heterogeneity of type: none of the 14 PPNG strains was identical, while the 168 non-PPNG strains were distributed into 64 S/A/Pc types. Fifty-seven percent (57%) of the PPNG and 86% of the non-PPNG isolates were of the WII/III serogroup. Chromosomally mediated resistance to penicillin, ampicillin, or both was exhibited by 14% of the non-PPNG isolates. Greater frequency of reduced susceptibility to cefotaxime, tetracycline, and chloramphenicol was also found among PPNG and non-PPNG strains, mostly of the WII/III serogroup. Twelve percent (12%) of the non-PPNG and 57% of the PPNG strains had multiple patterns of resistance, involving 2 to 4 antimicrobials of different class lines.
