Fracture of the femur, fish odour, and copper deficiency in a preterm infant.
نویسندگان
چکیده
A preterm baby boy with blood and bone changes of copper deficiency is described. Copper deficiency was suspected after fracture of the left femur during examination of the hip joint. A low serum copper concentration (2.7 mumol/l; 17.2 micrograms/100 ml) and caeruloplasmin (0.04 g/l; 0.004 g/100 ml) confirmed the diagnosis. Despite the introduction of solids at 18 weeks the copper concentration remained low, and treatment with copper sulphate (2.5 mg daily) was started at 6 months. Treatment was stopped at 9 months, when he was both physically and developmentally normal. When given a choline-containing vitamin preparation (Ketovite) he developed a fish odour because of the accumulation of trimethylamine. Withdrawal of this preparation at 6 weeks and substitution with a choline-free preparation (Abidec) was soon followed by disappearance of the odour. It is speculated that prematurity rather than copper deficiency was responsible for the poor activity of liver enzyme, trimethylamine oxidase.

Comparison of Vitamin D Level in Preterm and Term Infant–Mother Pairs: A Brief Study
Background: Recent studies have demonstrated the high prevalence of vitamin D deficiency in the general population. Pregnancy and preterm delivery are known as risk factors for vitamin D deficiency. Consequently, vitamin D level in women with preterm deliveries might vary from those with term pregnancies. In this study, we aimed to compare vitamin D level in term and preterm infant–mother pairs...
متن کاملNutritional aspects of metabolic bone disease in the newborn.
Correspondence to: Dr Steven Ryan. Metabolic bone disease (MBD) in the newborn predominantly affects preterm neonates, although there are a few reports of babies with congenital rickets after maternal vitamin D deficiency. Features of MBD in preterm neonates include radiological abnormalities such as fractures, rickets, and osteoporosis; biochemical features such as raised blood alkaline phosph...
متن کاملBilateral Neck Femur Fracture Following a Generalized Seizure- A Rare Case Report
Hip fractures are one of the most common injuries which present to an orthopaedic surgeon. Most of these cases are unilateral .Bilateral simultaneous femur neck fracture is a rare occurrence. We report a case of a bilateral neck femur fracture in a 30 year male following a generalized tonic clonic seizure in view of its rarity and also to increase the awareness of such rare injuries. The patien...
متن کاملOpen vertical sagittal fracture patella with fracture lateral condyle femur: approach to a rare injury
Patellar fracture is a relatively uncommon fracture especially the vertical sagittal type. In cases of high energy trauma injury, it is usually associated with fracture of ipsilateral distal femur or proximal tibia. However, the combination of vertical sagittal fracture patella and ipsilateral fracture lateral condyle is very rare. This necessitates judicious diagnosis and appropriate managemen...
متن کاملEffects of Hip Geometry on Fracture Patterns of Proximal Femur
Background: Some studies have previously shown that geometry of proximal femur can affect the probability of fracture and type of fracture. It happens since the geometry of the proximal femur determines how a force is applied to its different parts. In this study, we have compared proximal femur’s geometric characteristics in femoral neck (FNF), intertrochanteric (ITF) and Subtrochanteric (ST...
