Five cases of diphtheria were reported in Italy between January 1990 and June 2001. Three cases were confirmed microbiologically by the isolation of toxigenic Corynebacterium diphtheriae (two cases) and Corynebacterium ulcerans (one case). Over the same period, 11 cases of non-toxigenic C. diphtheriae infection were reported to the Italian Public Health Institute, from which the causative organism was isolated from a skin infection in one case and from the throat in the other ten. Seven of the throat isolates were associated with fever, severe pharyngitis and tonsillitis and were all biotype gravis. Because there are no standardized breakpoints, the antimicrobial sensitivities of C. diphtheriae were determined in accordance with the National Committee for Clinical Laboratory Standards guidelines for Streptococcus spp. other than Streptococcus pneumoniae. MICs for penicillin ranged between 0.125 and 0.250 mg l(-1) and 7 out of 11 strains had a minimal bactericidal concentration (MBC)/MIC ratio >or= 32. All strains were sensitive to clindamycin (MIC <or= 0.25 mg l(-1)), rifampicin (MIC <or= 1 mg l(-1)) and tetracycline (MIC <or= 2 mg l(-1)), and showed moderate susceptibility to cefotaxime (MIC 0.75-1.5 mg l(-1)). Molecular typing (ribotyping) demonstrated the presence of several distinct ribotypes. The ribotype designated 'D11' has been documented amongst strains isolated in the UK, Russia, Germany, Romania and Sweden. Ribotype 'D75' has only been documented in the UK. The C. ulcerans strain had a ribotype pattern identical to that found in recent isolates from the UK.

A diagnosis-prescribing study was performed in 5 Swedish counties during 1 week in November in 2000 and repeated in 2002. The aim of the present study was to analyse data for children 0-15y of age who consulted a general practitioner with symptoms of an infection. During the 2 weeks studied, 4049 children were consulted. Respiratory tract infections (RTI) were the predominant diagnoses, above all among the youngest children, while the proportion of urinary tract infections and skin infections increased with increasing age. Between the y 2000 and 2002, the proportion of children allocated the diagnosis streptococcal tonsillitis and pneumonia decreased (p<0.01 and p<0.001, respectively) while the proportion of common cold increased (p<0.001). Antibiotic prescribing decreased from 55% to 48% (p<0.001) for respiratory infections between the years studied. The only significant changes in type of antibiotics prescribed were the increase of isoxazolylpenicillins (p<0.001) used for skin infection and the decrease of macrolides (p=0.001). A diagnostic test was used in more than half of the consultations. Of children allocated a RTI diagnosis, 36% were prescribed antibiotics when a C-reactive protein test was performed compared to 58% in those not tested. Further studies are needed in general practice to determine the optimal use of near-patient tests in children with RTI.

In this study, we analyzed the antimicrobial resistance properties and T antigenic types of 511 isolates collected in Lisbon district, Portugal, from throat swabs of healthy subjects (n=341), during 2000-2002 and from diverse infection sites (n=170) of outpatients and inpatients, during 1999-2002. Erythromycin resistance was higher in tonsillitis/pharyngitis (27.4%) and skin infection isolates (21.1%), than in carriage and invasive isolates (<or=10%). Differences in erythromycin resistance among children and adults were noticed only for carriage isolates (9.3% in children and 21.1% in adults). Most erythromycin-resistant isolates from carriage (82.4%) and tonsillitis/pharyngitis (71.9%) showed the M phenotype. All M phenotype isolates (n=53) carried mef(A), whereas all MLS(B) phenotype isolates (n=19) carried erm(B) and not erm(A). Resistance to tetracycline [mediated by tet(M) in most isolates] was <or=6% in tonsillitis/pharyngitis and carriage isolates, 36.8% in skin infection isolates, and 44.1% in invasive isolates. The M phenotype increased since 2000, linked to a decrease of tetracycline resistance, and was predominantly associated with T1 in 2000-2001 and T12 in 2002 among carriage isolates, and with T8/25/Imp19 through 2000-2002 among tonsillitis/pharyngitis isolates. The majority (53%) of the tetracycline-resistant invasive isolates were nontypable. All isolates were susceptible to penicillin and chloramphenicol. This study showed that tetracycline and macrolide resistance frequency and phenotypes differ among GAS from various origins and changed over time. Moreover, T typing suggested that most drug-resistant isolates causing oropharyngeal carriage are distinct from the majority of isolates causing noninvasive and invasive infection.

During the period of 1995-2004, acute postinfectious glomerulonephritis was diagnosed in 322 children aged 1-16 years. An outbreak of acute postinfectious glomerulonephritis was registered in 1995, with a prevalence of 8.3 cases per 100,000 children; during 2003-2004 prevalence decreased and it was 2.2-2.4 cases per 100,000 children. Acute postinfectious glomerulonephritis was most frequently caused by upper respiratory tract infection (28.3%), following by tonsillitis (24%) and skin infection (24%). The mean interval between diagnosis of primary infection and onset of acute postinfectious glomerulonephritis was 14 days and did not differ by infection. The disease was more common in autumn (96 of the 322 cases, P<0.05). There were 4.3% of familial cases; no relapses occurred. Edema was observed in 70.3% of patients; 55.5% had elevated blood pressure according to their age. There were no proteinuria and hematuria in 17.6% and 1.7% of patients, respectively. Short-term renal failure was diagnosed in 32.9% of patients; in two cases, acute renal failure was severe and hemodialysis was started. No patient died.
