The Bonebridge is an active transcutaneous bone conduction implant recommended as a surgical option for adults and children (aged 5–18 years). Successful implantation of the Bonebridge is often restricted by an insufficient amount of temporal bone to house the transducer in the paediatric patient.
Method and results
In this unique paediatric case, bilateral Bonebridge devices were implanted simultaneously in the right sinodural angle and the left middle cranial fossa.
The simultaneous implantation of bilateral Bonebridge devices was well tolerated in this paediatric patient, with significant improvement in her hearing. The middle cranial fossa is a viable option for housing the transducer.
CHD is defined as structural defect(s) in the heart and proximal blood vessels present at birth. The National Cardiothoracic Center of Excellence, University of Nigeria Teaching Hospital (UNTH), Enugu, through the aid of visiting Cardiac Missions has managed a significant number of patients within the last 3.5 years.
The objective of this study was to review surgical options and outcome of complex CHD among patients attending UNTH, Enugu, Enugu.
Materials and Method
During the period of 3.5 years (March, 2013 to June, 2016), a total of 20 cases of complex CHD were managed by cardiac missions that visited UNTH, Enugu. Their case notes and operating register were retrieved, reviewed, and analysed using SPSS version 19 (Chicago).
There were eight females and 12 males, with a ratio of 2:5. The age range was from 5 months to 34 years with a mean of 1.7. Among all, five patients died giving a mortality rate of 25%. The operative procedures ranged from palliative shunts to complete repair. The outcome was relatively good.
Complex CHD are present in our environment. Their surgical management in our centre is being made possible by periodic visits of foreign cardiac missions.
The associations with weather and bathing water quality on infectious intestinal disease (IID) were investigated using data from two Scottish NHS Board areas. Monthly counts of viral and non-viral gastrointestinal infections were modelled as a smooth function of temperature, relative humidity and average monthly counts of faecal indicator organisms, respectively, adjusting for season and long-term trend effects. Strong seasonal patterns were observed for each group of pathogens. Peak viral gastrointestinal infection was in May while that of non-viral gastrointestinal infections was in July. A statistically significant negative association existed between weather (temperature and humidity) and viral infection. Average levels of non-viral gastrointestinal infections increased as temperature and relative humidity increased. Increasing levels of faecal indicator organisms in bathing waters were also associated with an increase in the average number of viral and non-viral gastrointestinal infections at the ecological level. Future climate change and prolonged precipitation events may result in increasing levels of faecal indicator organisms in bathing waters leading to likely increases in IIDs.
Preliminary investigations at two archaeological sites in south-eastern Nigeria are presented. These sites are the ancient stone circle in Ikom and the crescent shape of an ancient iron slag heap at Lejja, Nsukka. Here, we discuss the celestial alignments of these objects, and other traditional rites in this part of Nigeria, that seem to suggest some possible astronomical connections.
