Treatment of streptococcal endocarditis with a single daily dose of ceftriaxone sodium for 4 weeks. Efficacy and outpatient treatment feasibility

OBJECTIVE--To evaluate the efficacy and safety of ceftriaxone sodium in the treatment of streptococcal endocarditis. DESIGN--An open, multicenter, noncomparative study with a follow-up of patients for 4 months to 5 years. SETTING--Internal medicine wards and outpatient clinics of hospitals of various sizes in three European countries. PATIENTS--Fifty-nine patients with defined criteria for streptococcal endocarditis. INTERVENTION--Ceftriaxone sodium administered at a once-daily dose of 2 g for 4 weeks. MAIN OUTCOME MEASURES--Clinical outcome and microbiological cure rate. RESULTS--Among the 59 patients, 55 completed the treatment and were followed up for 4 months to 5 years. No patients showed evidence of relapse. Treatment was completely uneventful in 42 patients (71%). A cardiac valve was replaced in four patients (7%) receiving antimicrobial therapy and in six patients (10%) who had completed antimicrobial therapy. One of the 10 valves taken for culture at surgery was positive, but only for microorganisms that were different from the microorganism isolated before the treatment. The treatment had to be interrupted in four patients because of drug allergy. Other side effects were mild except for two cases of reversible neutropenia. The treatment was easy to administer: 27 patients (46%) had no permanent intravenous catheter at any time, seven patients (12%) had such a catheter for less than 4 days. Twenty-three patients (39%) were discharged from the hospital less than 2 weeks after admission. CONCLUSIONS.--Ceftriaxone sodium administered at a once-daily dose of 2 g appears to be an effective and safe treatment of streptococcal endocarditis. In hospitals, this agent may be more convenient to administer than penicillin G with or without aminoglycosides. Some patients may even be treated as outpatients

Piezoelectric osteotomy in hand surgery: first experiences with a new technique

BACKGROUND: In hand and spinal surgery nerve lesions are feared complications with the use of standard oscillating saws. Oral surgeons have started using a newly developed ultrasound bone scalpel when performing precise osteotomies. By using a frequency of 25–29 kHz only mineralized tissue is cut, sparing the soft tissue. This reduces the risk of nerve lesions. As there is a lack of experience with this technique in the field of orthopaedic bone surgery, we performed the first ultrasound osteotomy in hand surgery. METHOD: While performing a correctional osteotomy of the 5th metacarpal bone we used the Piezosurgery(® )Device from Mectron [Italy] instead of the usual oscillating saw. We will report on our experience with one case, with a follow up time of one year. RESULTS: The cut was highly precise and there were no vibrations of the bone. The time needed for the operation was slightly longer than the time needed while using the usual saw. Bone healing was good and at no point were there any neurovascular disturbances. CONCLUSION: The Piezosurgery(® )Device is useful for small long bone osteotomies. Using the fine tip enables curved cutting and provides an opportunity for new osteotomy techniques. As the device selectively cuts bone we feel that this device has great potential in the field of hand- and spinal surgery

Adverse Drug Reactions in Hospital In-Patients: A Prospective Analysis of 3695 Patient-Episodes

Adverse drug reactions (ADRs) are a major cause of hospital admissions, but recent data on the incidence and clinical characteristics of ADRs which occur following hospital admission, are lacking. Patients admitted to twelve wards over a six-month period in 2005 were assessed for ADRs throughout their admission. Suspected ADRs were recorded and analysed for causality, severity and avoidability and whether they increased the length of stay. Multivariable analysis was undertaken to identify the risk factors for ADRs. The 5% significance level was used when assessing factors for inclusion in multivariable models. Out of the 3695 patient episodes assessed for ADRs, 545 (14.7%, 95% CI 13.6–15.9%) experienced one or more ADRs. Half of ADRs were definitely or possibly avoidable. The patients experiencing ADRs were more likely to be older, female, taking a larger number of medicines, and had a longer length of stay than those without ADRs. However, the only significant predictor of ADRs, from the multivariable analysis of a representative sample of patients, was the number of medicines taken by the patient with each additional medication multiplying the hazard of an ADR episode by 1.14 (95% CI 1.09, 1.20). ADRs directly increased length of stay in 147 (26.8%) patients. The drugs most frequently associated with ADRs were diuretics, opioid analgesics, and anticoagulants. In conclusion, approximately one in seven hospital in-patients experience an ADR, which is a significant cause of morbidity, increasing the length of stay of patients by an average of 0.25 days/patient admission episode. The overall burden of ADRs on hospitals is high, and effective intervention strategies are urgently needed to reduce this burden
