Epidemiology and laboratory diagnosis of infection with viral and bacterial pathogens in infants hospitalized for suspected sepsis

A prospective study was conducted to determine the frequency and distribution of bacterial and viral pathogens in infants hospitalized with suspected sepsis and to evaluate the potential of virus detection for improving patient management. A causative organism was detected in 157 (67%) of 233 previously healthy infants less than 3 months of age, who had been hospitalized for suspected sepsis: 19 (8%) had bacterial infections, 135 (58%) had viral infections, and 3 (1%) had mixed viral-bacterial infections. Viral infections occurred in a seasonal pattern: enteroviruses were responsible for most of the hospitalizations during summer and fall (65/110; 63%) and respiratory syncytial and influenza A viruses were responsible for most of the infections during winter (44/81; 55%). In contrast, bacterial infections were not seasonally distributed. Virus was detected in 33% of the 138 infected infants within 24 hours, and in 64% within 3 days. We conclude that viral infections are prevalent among infants hospitalized for suspected sepsis, and most can be detected early enough to influence patient management.     

Nurses' Logs as an Evaluation Tool for School-Based Violence Prevention Programs

ABSTRACT: Programs for preventing violence among youth should be evaluated to determine if they are effective. Nurses' logs appear to be a useful tool for evaluating school-based violence prevention programs. The logs provide a record of students' visits to the school nurse that can be used to determine if a violence prevention program is associated with a reduction in fighting—and other injury-related nurse visits. This method has many strengths: it is simple and inexpensive, it does not interrupt the school routine, it permits school-level rather than student-level data collection, it provides a ready "baseline," and it allows continuous data collection. However, potential limitations do exist. For example, the method may provide insufficient information and may be affected by factors unrelated to the intervention. School officials can increase the usefulness of the logs by encouraging standardization and providing training in their use.     

Deferred treatment for prostate cancer

The clinical outcome of 278 prostate cancer patients managed by a deferred treatment policy was analysed retrospectively. Following TURP or biopsy, all patients were asymptomatic and deemed suitable for management by a deferred treatment policy, i.e. hormone therapy or other forms of treatment were only initiated if and when symptomatic progression occurred. The overall 5-year survival rate was 30%; 18% of patients died from other causes without needing treatment for their prostate cancer; 11% were alive and untreated after 5 years' follow-up; 17% died from prostate cancer without further treatment. Poor tumour grade, anaemia, metastatic disease, a short history, presentation with retention, and a raised serum creatinine at presentation were associated with a poor prognosis.     

Is the risk of cancer increased in Asians living in the UK?

The pattern of cancer in white and Asian (Indian, Pakistani, and Bangladeshi) children living in the West Midlands Health Authority Region was investigated using age standardised incidence rates. Two sets of rates were calculated, a 10 year rate (1982-91) using survey based estimates of the ethnic population and a four year rate (1989-92) using the ethnic population counts from the 1991 census. The 10 year rates showed a significantly higher annual incidence of cancer in Asian (159.1/million/year) than in white (130.8) children. The pattern of cancers in Asian children was different, with an excess of lymphomas and germ cell tumours, and a deficit of rhabdomyosarcomas. These findings were confirmed by the four year rates. Although underestimation of the Asian population probably contributes to the apparent excess, there remains cause for concern that UK Asian children may be at higher risk of cancer. Accurate ethnic population figures and confirmatory studies are urgently required.     

The changing blueprints of the british NHS: The white papers of 1944 and 1989

It has recently been pointed out that the 1989 White PaperWorking for Patients, which provides the basis for the current reforms of the British National Health Service, has some common features with the 1944 White PaperA National Health Service, which was the unadopted model for the service produced by the Wartime Coalition Government. Moreover, it is likely that the Conservatives, if elected in the 1945 General Election, would have introduced a service based on a modified version of the 1944 document. We can compare these two blueprints to shed some light on Conservative thinking on health care over a period of nearly 50 years. There are some similarities in terms of the notions of purchaser and provider, contracts and pluralism. However, there are striking contrasts, notably in their attitude towards planning versus competition and local democracy versus patronage. It is claimed that the profound differences outweigh the apparent similarities and consequently the two blueprints show the discontinuity rather than the continuity of Conservative thinking on health care.     

What role does gemtuzumab ozogamicin have in the treatment of acute myelogenous leukemia?

Gemtuzumab ozogamicin (GO) is a novel, targeted chemotherapy designed to treat acute myeloid leukemia (AML). GO consists of an antitumor antibiotic, calicheamicin, linked to a humanized monoclonal antibody against CD33. It has been approved in the United States since 2000 to treat CD33+ AML in first relapse in older adults who are not candidates for cytotoxic therapy. Beyond this indication, the role of GO is evolving. Single-agent GO has a limited role in de novo AML. Incorporation of GO into standard induction treatment in de novo and relapsed AML is feasible. Comparative phase III studies of such an approach are ongoing. GO is associated with serious toxicities, such as infusional reactions, transient liver function test abnormalities, and veno-occlusive disease of the liver, especially in patients who undergo hematopoietic stem cell transplantation.     

Glucocorticoids as an adjuvant treatment to intravenous antibiotics for cystic fibrosis pulmonary exacerbations: a UK Survey.

Oral glucocorticoids are widely used to treat exacerbations of asthma and COPD. A role for their use in treating exacerbations in Cystic Fibrosis (CF) is not proven. We describe the current practice, amongst UK adult CF physicians, of oral glucocorticoid use as an adjuvant to intravenous (IV) antibiotic treatment during CF pulmonary exacerbation (P EX). The survey also examined whether physicians thought a randomised controlled trial (RCT) was necessary and their willingness to participate patients in such a trial. Eighty one percent of physicians replied. All of them used corticosteroids with P EX. Most physicians supported the need for a RCT and would be willing to enroll consenting patients in the trial. This survey highlighted the need for a RCT which would examine the role of adjuvant corticosteroids to IV antibiotics in CF P EX.
