Diagnosis of childhood pneumonia: clinical assessment without radiological confirmation may lead to overtreatment.

OBJECTIVES: Consensus guidelines discourage the use of routine radiologic confirmation of clinically diagnosed pneumonia in children. The goal of the present study was to assess the degree of antibiotic overtreatment resulting from this approach. DESIGN: This was a prospective data collection. SETTING: This was performed in 5 urgent care clinics in Jerusalem, Israel. PARTICIPANTS: This study was composed of previously healthy children between 2 months and 18 years of age who presented with a chief complaint of fever, cough, or dyspnea between August 1, 2007, and March 15, 2008, by for whom chest x-rays were obtained because of clinical suspicion of pneumonia. OUTCOME MEASURES: Outcome measure was percentage of children with clinical findings associated with pneumonia (hypoxia, tachypnea, rales, dyspnea) who did not have radiological findings of pneumonia. RESULTS: With the exception of wheezing, 55% to 65% of children with specific signs and symptoms did not have radiologic pneumonia. A similar range of children with a combination of the signs did not have radiologic pneumonia. For wheezing, alone or in combination, the percentages were higher. On multivariate analysis, only fever was found to be predictive of pneumonia. Wheezing was found to be negatively predictive. CONCLUSIONS: Treatment of childhood pneumonia on the basis of clinical parameters alone with no chest x-ray confirmation may lead to a large portion of children receiving unnecessary antibiotic therapy. In an era when the emphasis is to decrease antibiotic resistance, radiological confirmation of pneumonia should be obtained when possible.

Pylephlebitis due to perforated appendicitis in a teenager.

Pylephlebitis, a septic thrombophlebitis of the portal vein, is a life-threatening complication of intraabdominal infections, commonly associated with acute appendicitis in children, and diverticulitis in adults. A 13-year-old boy was admitted for high fever and jaundice. On the fifth day of hospitalization, ultrasound Doppler flow and Computer Tomography scan studies showed thrombosis of the portal vein and acute appendicitis. The patient was treated with antibiotics, anticoagulation and laparotomy with appendectomy. No thrombophilic risk factors were diagnosed. Our aim is to improve physicians' awareness of this complication and emphasize the importance of early diagnosis and appropriate therapy in children in order to reduce serious complications and long-term sequels.

Is omitting post urinary-tract-infection renal ultrasound safe after normal antenatal ultrasound? An observational study.

BACKGROUND: Guidelines recommend obtaining a renal ultrasonogram (RUS) for young children after a first urinary tract infection (UTI). OBJECTIVE: The aim of the current study was to assess the concordance of prenatal and post-UTI RUS findings in children with a first simple UTI. METHODS: This was a prospective study and included all children aged 5 years or younger who were hospitalised with a first simple UTI (determined as clinical response and normalisation of temperature within 48 h on initiation of antibacterial therapy with no complications). Data were collected from each child regarding the results of prenatal and post-UTI RUS. RESULTS: Overall, 250 children were included in the study and the results of late-pregnancy and post-UTI RUS were available for 84% (n = 209). Complete concordance between the two RUS was demonstrated in 96% (n = 201). The predictive value of normal antenatal to normal post-UTI RUS was 96% (95% CI: 93% to 99%). These results include four children with mild transient pelvic dilatation. In eight children in whom renal anomalies were demonstrated only in post-UTI RUS, the influence of these anomalies on the children's management was negligible. CONCLUSIONS: Prenatal-RUS have been performed in most children <5 years old hospitalised with a first simple UTI. Concordance with post-infection tests is very high. Findings which appear only in post-infectious RUS usually have negligible effects on children's management. Thus, in such children with normal antenatal RUS omitting post-UTI RUS could be considered.
