OBJECTIVE: Lymphadenitis colli due to NTM should always be considered in children with cervical Lymphadenitis. For Germany there is a lack of data concerning the incidence, the epidemiology, the diversity and frequency of the different bacteria, the diagnosis, the clinical manifestation and the medical treatment. METHODS: By means of a questionnaire, which was retrospective for 1985 to 1994 and was sent to 277 children's hospitals in Germany, we collected data on Lymphadenitis colli in Germany. In our study we also incorporated cases from the "National Laboratory for Mycobacteria" in Borstel as well as six cases from our hospital in Mainz. Therefore our data includes both clinical (28) and laboratory (30) cases. Additionally we screened the literature on "Lymphadenitis colli in children due to NTM". RESULTS: A total of 51 cases of Lymphadenitis due to NTM could be identified. The illness occurs typically in young children up to six years of age. The most frequent cause were species of the Mycobacterium avium-intracellulare-scrofulaceum complex. Except for the local diagnosis of a cervical Lymphadenitis other clinical symptoms are missing, just as specific laboratory parameters with a subacute or chronic course. The tuberculin skin test can be false positive. The diagnosis is confirmed by biopsy and histology as well as through microbiological tests. CONCLUSIONS: The best treatment is complete surgical excision, whereas the importance of additional or exclusive treatment with Clarithromycin, Rifabutin and other antibiotics could not be clarified completely. But in patients with AIDS Rifabutin and other drugs could perhaps be useful, even for prophylaxis. Also if complete excision is impossible, treatment with certain drugs (Clarithromycin or Azithromycin in combination with Rifampicin) will be recommended. It still remains in question if NTM infections in children are really increasing.

In the winter of 1998-1999 an outbreak of pneumococcal pneumonia occurred among Ranger students undergoing high-intensity training. Thirty pneumonia cases (attack rate = 12.6%) were identified among a group of 239 students. Eighteen students were hospitalized; Streptococcus pneumoniae-positive cultures were detected in 11 (61.1%) of these 18 hospitalized cases. Pneumococci were also identified in throat swabs of 30 (13.6%) of 221 nonhospitalized students surveyed. Serum antipneumolysin seroconversions were detected in 30 (18.3%) of 164 students tested. An association between development of serum antipneumolysin antibody and pneumococcal pharyngeal carriage/colonization was found. Of 30 seroconverters, eight (26.7%) had S. pneumoniae-positive cultures compared with only 17 (12.7%) of 134 nonseroconverters (relative risks = 2.02, 95% confidence interval = 1.02-4.02, p = 0.05). The outbreak was controlled by administrating lowdose, oral azithromycin prophylaxis (250 mg weekly for 2 weeks) and was associated with a 69% reduction in pneumococcal carriage and a 94% reduction in pneumonia rates.

From mid 1997 to end of 1999, there was a sexually-transmitted infectious syphilis outbreak mainly in heterosexual people in British Columbia, Canada, that was concentrated in Vancouver. The rate across the province increased from less than 0.5 to 3.4 per 100000, and the rate in Vancouver reached 12.9 per 100000. We aimed to eliminate the syphillis outbreak by treating people at risk of infection. In 2000, a targeted mass treatment programme provided azithromycin (1.8 g orally) to 4384 at-risk residents in this city. After the programme, syphilis frequency fell significantly for 6 months (p=0.016), but rose again in 2001. Results from curve fitting analyses showed that the number of cases in 2001 (177) was higher than expected (0.0001<p<0.0044). This rate rebound and the absence of a sustained effect suggest that targeted mass treatment for syphilis, even though feasible, should not be done routinely.
