Aim To explore [fluorine‐18]‐fluoro‐2‐deoxy‐d‐glucose positron‐emission‐tomography/computed tomography (18FDG‐PET/CT) in patients where standard investigations were non‐diagnostic. Methods We reviewed medical records of previously healthy children who had 18FDG‐PET/CT performed at Copenhagen University Hospital in 2015–2020 due to unexplained fever. Results Thirty‐five of 819 paediatric 18FDG‐PET/CT were performed due to unexplained fever. The final diagnoses were malignancy (11%), infections (23%), inflammatory diseases (43%) and miscellaneous (26%). 18FDG‐PET/CT was diagnostic in six cases with Takayasu's arteritis, tuberculosis, Langerhans cell histiocytosis and Ewing sarcoma. Sixteen cases had focal 18FDG‐uptake, but 18FDG‐PET/CT could only differentiate malignancy, infection and inflammation in three cases. In six cases with inflammatory diseases and no focal signs, PET/CT was normal except increased non‐specific 18FDG‐uptake in bone marrow and spleen in five cases. One case was false positive (suspicion of appendicitis) and two false negative (leukaemia and inflammatory disease). Conclusion 18FDG‐PET/CT was diagnostic, or contributed to the diagnosis, in several children with unexplained fever referred to a tertiary centre. Challenges comprised (i) only increased non‐specific 18FDG‐uptake in bone marrow and spleen in half of cases with inflammatory diseases, (ii) no differentiation between complicated infections, malignancy and inflammation in most cases with focal processes and (iii) a small risk of false positive and false negative results.
Background The highest neonatal mortality is in Sub-Saharan Africa, where neonatal sepsis accounts for approximately 50%. At Pemba Island, Tanzania, we examined the use of prophylactic antibiotics in neonates and related it to WHO guidelines and compared clinical signs of infection with the use of antibiotic treatment; furthermore, we aimed to investigate all use of antibiotic treatment in the neonatal period. Method This prospective observational cohort study was performed from 1 January 2022 to 15 April 2022 at a district hospital on Pemba Island, Tanzania. Women admitted in early established or active labour, and their neonates, were eligible for inclusion. We used questionnaires for mother and health worker and examined the neonates 2 h after birth. Follow-up was made at discharge or at 18 h of life, and days 7 and 28. Results We included 209 women and their 214 neonates. The neonatal mortality was 5 of 214 (23 per 1000 live births). According to WHO guidelines 29 (13.6%) had ≥ 1 risk factor for infection. Of these, three (10.3%) received prophylactic antibiotic treatment; only one (3.4%) received the correct antibiotic drug recommended in guidelines. Thirty-nine (18.2%) neonates had ≥ 1 clinical indicator of infection and 19 (48.7%) of these received antibiotic treatment. A total of 30 (14.0%) neonates received antibiotics during the study period. Twenty-three (76.7%) were treated with peroral antibiotics. Conclusion Adherence to WHO guidelines for prophylactic antibiotic treatment to prevent neonatal infection was low. Further, only half of neonates with clinical signs of infection received antibiotics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
