We report about the juvenile and adolescent pelvic type of CRMO in 7 girls and 4 boys. The results show from solitary up to 7 pelvic lesions (average 3 lesions) predominantly in the acetabular and paraacetabular region (sometimes with hip joint effusion as a sign for concomitant coxitis).Tc99m-bone-scan is helpful to evaluate exactly the pattern of bone affection. We find 3 stages of an primarily chronic, non-purulent osteomyelitis going along with a "plasma-cell-sclerotic process", leading to a Garre-type sclerosing end-stage, which probably heals after some years spontaneously, projecting on clinical symptoms and radiological appearance. The concomitant coxitis ("sympathetic coxitis") is clinically often in the foreground, but reversible. Pain in case of CRMO responds surprisingly well on medication with acithromycine.Knowing about CRMO in its different clinical appearances - especially concerning what we call "sympathetic coxitis" - can be a useful for pediatric rheumatologists and orthopedic surgeons, as well as MRI-focused radiologists and pathologists. Therapy might find a useful drug in acithromycine.In conclusion we d like to point out, that CRMO is one entity under the "roof" of the so called SAPHO-syndrome, which again shows us, that SAPHO-syndrome ist not a diagnosis itself but more a sign-post on the way to a correct diagnosis.

BACKGROUND: Azithromycin is an azalide antibiotic with a similar antibacterial spectrum to erythromycin but with greater gram-negative activity. Azithromycin displays a favorable pharmacokinetic profile, with improved absorption and higher sustained tissue concentrations compared with erythromycin. This results in a prolonged elimination half-life, suggesting a potential for treating continuous ambulatory peritoneal dialysis (CAPD) peritonitis. OBJECTIVE: This study aimed to define the potential role of azithromycin in treating CAPD peritonitis. DESIGN: The pharmacokinetics and peritoneal dialysis (PD) clearance of azithromycin were studied following a single 500-mg oral dose of azithromycin. Blood and dialysate samples were taken over a 10-day period and assayed using high-pressure liquid chromatography. SETTING: The study took place within the Renal Unit at Southend Hospital NHS Trust, a district general hospital in the United Kingdom. PATIENTS: Eight patients with oliguric end-stage renal failure without peritonitis maintained on CAPD (3 x 2 L/day). RESULTS: Peak plasma concentrations occurred at 2-3 hours with 0.35-1.35 microg/mL (mean 0.75). The mean elimination half-life was 84.55 hrs, and plasma clearance was 21.93 L/hour. This compares with values of greater than 40 hours and 40.8 L/hour reported in healthy volunteers. After 8 hours, the mean dialysate concentration was 0.07 microg/mL; PD clearance was 0.06 L/hr. CONCLUSION: Azithromycin is not substantially removed by CAPD in the absence of peritonitis and cannot be recommended for widespread use in this setting at present. However, the successful use of azithromycin in CAPD peritonitis, due possibly to an intracellular drug transport mechanism, has been reported. Future research should address this possibility.

Economic evaluation of three methods of treating urogenital chlamydial infections in the emergency department.

We attempted to determine the economic impact of three alternatives for the treatment of chlamydial infections in the emergency department: a written prescription for 7 days of doxycycline therapy (D-RX); a prepacked 7-day supply of doxycycline (D-ED); or a single 1-g dose of azithromycin (AZI). Data inputs for the model were obtained from both patient experience and literature sources. Primary health outcomes of the model were number of infection relapses. Economic outcomes were costs for initial treatment, treatment of relapses, and treatment of complications of relapse. For every 1000 patients, D-ED and AZI resulted in 21.6 (-10 to -41) and 36.2 (-25 to -63) fewer relapses than D-RX, respectively; AZI resulted in 14.6 (-35 to -4) fewer relapses than D-ED. Total costs were decreased for D-ED and AZI versus D-RX by $18,879 (-$39,000 to -$8000) and $24,039 (-$59,000 to -$10,000), respectively, and AZI resulted in a total cost decrease of $5160 (-$35,000 to +$6000) versus D-ED. Both D-ER and AZI decreased infection relapses and overall health care costs compared with D-RX. Also, AZI resulted in additional decreases in relapses versus D-ED, although the incremental impact on cost was inconclusive.
