BACKGROUND: Fear of infection in neonatal intensive care units (NICUs) often leads to early use of empiric broad-spectrum antibiotics, a strategy that selects for resistant bacteria. We investigated whether the emergence of resistant strains could be halted by modifying the empiric antibiotic regimens to remove the selective pressure that favours resistant bacteria. METHODS: Two identical NICUs were assigned to different empiric antibiotic regimens. On unit A, penicillin G and tobramycin were used for early-onset septicaemia, flucloxacillin and tobramycin were used for late-onset septicaemia, and no broad-spectrum beta-lactam antibiotics, such as amoxicillin and cefotaxime were used. In unit B, intravenous amoxicillin with cefotaxime was the empiric therapy. After 6 months of the study the units exchanged regimens. Rectal and respiratory cultures were taken on a weekly basis. FINDINGS: There were 436 admissions, divided equally between the two regimens (218 in each). Three neonates treated with the penicillin-tobramycin regimen became colonised with bacilli resistant to the empirical therapy used versus 41 neonates on the amoxicillin-cefotaxime regimen (p<.0001). The relative risk for colonisation with strains resistant to the empirical therapy per 1000 patient days at risk was 18 times higher for the amoxicillin-cefotaxime regimen compared with the penicillin-tobramycin regimen (95% CI 5.6-58.0). Enterobacter cloacae was the predominant bacillus in neonates on the amoxicillin-cefotaxime regimen, whereas Escherichia coli predominated in neonates on the penicillin-tobramycin regimen. These colonisation patterns were also seen when the units exchanged regimens. INTERPRETATION: Policies regarding the empiric use of antibiotics do matter in the control of antimicrobial resistance. A regimen avoiding amoxicillin and cefotaxime restricts the resistance problem.
OBJECTIVES: To analyse the pathology diagnosed on the basis of the gastroscopies requested from a primary care centre (PCC). Assessment and treatment of Helicobacter pylori (HP) infection. DESIGN: Retrospective and descriptive. SETTING: Urban PCC. PATIENTS: Those over 14 who had a gastroscopy for a diagnostic purpose, requested by their primary care doctor during 1997. MEASUREMENTS: Review of clinical records and gastroscopy reports analysing: personal data, reasons for request, prior treatment, diagnoses, treatment to eradicate HP, later referral to the digestion specialist and waiting-time for the gastroscopy. RESULTS: 206 gastroscopies were performed, 139 for epigastralgia (67%) and 73 for heartburn (35%). 161 patients (78%) had had previous treatment, with alkalines used in 94 cases (45%). The most common diagnoses were: 54 normal (26%), 60 hiatus hernias (30%), 43 oesophagitis (21%), 18 duodenal ulcers (9%) and 4 gastric ulcers (2%). The Helicobacter pylori study was positive in 67 cases, with triple treatment (amoxycillin, clarithromycin and omeprazole) to eradicate it given for 7 days in 36 cases (54%). Referral to the specialist of 3% of the patients. Waiting-time for the performance of the gastroscopy: 60 days (SD: 35). CONCLUSIONS: Gastroscopy is a diagnostic method habitually used in our PCC. The pathology diagnosed is mainly treated in primary care. Given the current controversy about actions at determined clinical entities, standardisation of criteria used by professionals at different care levels is very important. This standardisation should affect the indications of the examinations, and the treatment and follow-up of the pathologies. The reduction in waiting-time for a gastroscopy could possibly modify the prescription and duration of the prior treatment.
Perianal streptococcal dermatitis is a bright red, sharply demarcated rash that is caused by group A beta-hemolytic streptococci. Symptoms include perianal rash, itching and rectal pain; blood-streaked stools may also be seen in one third of patients. It primarily occurs in children between six months and 10 years of age and is often misdiagnosed and treated inappropriately. A rapid streptococcal test of suspicious areas can confirm the diagnosis. Routine skin culture is an alternative diagnostic aid. Treatment with amoxicillin or penicillin is effective. Follow-up is necessary, because recurrences are common.
