ABSTRACT
Background: Ultrasound (US) is the first choice of imaging in neonates presenting with persistent jaundice to exclude surgically correctable causes and differentiate obstructive from nonobstructive causes. Previous studies on normal dimensions of gallbladder (GB) and common bile duct (CBD) recruited adults and children spread across a wide age group.Aims: This study aimed to determine GB and CBD normal dimensions in a large homogeneous neonatal population as well as guide decision regarding pre-US fasting in neonates who require GB evaluation.Materials and Methods: Five hundred and twenty-eight healthy newborns were recruited between May 2009 and May 2011. The widest intraluminal anterior-posterior diameters of GB and CBD were measured. Neonatal age in days, sex, birth weight, weight and height, gestational age at delivery, and time interval since last feed recorded.Results: The mean age was 9.56 ± 7.66 days, and 50.6% were males. The mean CBD diameter was 1.16 ± 1.61 mm while the mean GB diameter was 4.42 ± 2.16 mm. GB and CBD were clearly seen and measurable in 297 (55.8%) neonates and 237 (44.38%) neonates, respectively. There was a significant correlation between CBD diameter and GB diameter (P = 0.04) but no correlation with any demographic parameter. GB visualization was not dependent on time interval from last feed.Conclusion: Mean neonatal values for CBD and GB were established, but neonates have a wider range of GB diameters compared with older children, so GB diameter may not be a reliable parameter for neonatal GB pathologies. GB visualization was not dependent on time interval from last feed; hence, a recent feed should not delay emergency scans, especially in ill neonates

Background: Publicprivate partnership (PPP) has become a popular model used by public sector organizations that are usually under-funded by their respective governments to render services in fulfillment of their egalitarian responsibilities and goals. Lately, the health sector has been a recipient of such initiatives and the trend is growing. However, the successful delivery of services to patients is sometimes hampered because of difficulties encountered in both the development and interpretation of clauses contained in agreements including Memoranda of Understanding between the parties. The anticipated outcomes and impact often remain elusive due to the tensions encountered during implementation.Aim and Objective: The aim of this study was to determine the current operational status as well as explore potential benefits and challenges of the use of the PPP model in radiology departments of selected teaching hospitals within three South-Western States of Nigeria (Lagos, Ogun, and Oyo). It is hoped that the study findings would provide useful data needed for improvement of the PPP model as it is being currently practiced.Materials and Methods: This was a qualitative study in which 138 closed- and open-ended questionnaires were administered to all cadres of staff in radiology departments of the selected hospitals teaching hospitals within three South-Western States of Nigeria (Lagos, Ogun, and Oyo).Results: There was a 100% response from the participants. The age range of the participants was 2565 years. Study findings showed that almost all radiological equipment can be acquired through PPP. There was improved service delivery and residency training with PPP. Jurisdictional conflict was the greatest challenge.Conclusion: PPP is a viable option that should be encouraged by government for the purchase of equipment in hospitals
