Aim:β‐Glucuronidase activity is increased in the cerebrospinal fluid (CSF) of patients with bacterial meningitis. The aim of this study was to investigate the β‐glucuronidase activity in the cell‐free CSF of bacterial meningitis and its course during treatment, and compare it with other CSF parameters. Methods: The β‐glucuronidase activity, cell number, protein concentration and CSF/blood glucose ratio were measured in 43 consecutive infants and children with bacterial meningitis, and 97 control subjects. Patients had one or two follow‐up lumbar punctures. Results: The β‐glucuronidase activity was increased early in bacterial meningitis, even when the other CSF parameters were undisturbed. Before treatment, the median activity in affected children was 136umoles 4‐methylumbelliferone l‐1 h‐1 (range 44–826) and in controls 14 (7–23). In all patients who improved, the activity was lower in the follow‐up CSF samples. Six to 12 h after starting treatment, the median activity was already reduced by 59%. The other CSF parameters showed a variability during the first 24 h of treatment independently of the course of the disease. Multiple comparisons of the CSF parameters in 17 patients who had two follow‐up punctures showed that the β‐glucuronidase activity was the best prognostic index. Conclusion: β‐Glucuronidase activity in the CSF is a reliable indicator of bacterial meningitis, which can identify the response to treatment early in the course of illness. The enzyme activity is increased early in the disease, even when the other laboratory parameters from the CSF remain normal.

Objectives: Immature gut motility in very low birth weight infants causes feeding intolerance. We evaluated the effect of domperidone, a prokinetic agent, on gastric emptying in very low birth weight infants. Methods: The study was conducted in a crossover design. Gastric emptying was assessed ultrasonographically by measuring the time it took the antral cross sectional area of the stomach to reach half of the value of the 1st measurement on 2 occasions: (1) upon administration of domperidone (0.3 mg/kg/8 h p.o.) for at least 2 days and (2) while patients received an equal quantity of sterile water. 11 infants were randomly assigned to receive domperidone before the 1st measurement and the remaining afterwards. There was a 3–5 day interval between the 2 measurements. At the time when both measurements were performed, every neonate had been receiving the same quantity and quality of milk. 12 infants were formula-fed while 10 were fed their own mother’s supplemented milk. Results: 22 infants with a mean (SD) birth weight of 1,377 g (319) and a mean (SD) gestational age of 30.2 weeks (2.1) were studied. The mean (SD) antral cross sectional area half-value time (in minutes) was 47.6 (23.9) in the domperidone group and 68.2 (25.5) in the control group (p = 0.008). There was no significant difference between formula-fed neonates and neonates fed their own mother’s milk in either group. Conclusions: Domperidone significantly reduces gastric emptying in preterm neonates, and this may account for its effect in cases of disturbances related to gut motility.

The prevalence, resistance patterns and serotypes of antibiotic-resistant Streptococcus pneumoniae strains recovered from Greek carriers under 24 months of age were studied. From February 1997 to April 1998, nasopharyngeal cultures were performed in 1,269 children (ages 2-23 months, median 11 months) living in various areas of central and southern Greece. Resistance (including both intermediate and resistant isolates) to one or more antimicrobial agents was found in 132 of the 421 (31%) Streptococcus pneumoniae isolates, as follows: penicillin, 9% intermediate, 7.6% resistant; cefotaxime, 5.2% intermediate, 0.5% resistant; erythromycin, 0.7% intermediate, 18.1% resistant; clindamycin, 0.2% intermediate, 12.4% resistant; tetracycline, 0.7% intermediate, 16.4% resistant; chloramphenicol, 12.4% resistant; and trimethoprim-sulfamethoxazole, 3.8% intermediate, 14.3% resistant. The MICs of penicillin for 66% of the penicillin-nonsusceptible pneumococci were 1-4 microg/ml. Multidrug resistance was found in 64% of penicillin-nonsusceptible and 37% of penicillin-susceptible strains. Sixty-two percent of the penicillin-susceptible, multidrug-resistant strains belonged to serotype 6B and were resistant to all five non-beta-lactam agents tested. This notable serotype 6B resistance pattern was described for the first time in a previous study performed from December 1995 to February 1996 in the city of Patras, southwestern Greece. Seventy-two percent of antibiotic-resistant isolates belonged to serotypes 6B, 9V, 14, 18C, 19F and 23F. These results document the spread of resistant pneumococcal strains in central and southern Greece, many of which are multidrug resistant.
