PURPOSE: Trimethylamine N-oxide (TMAO) is a biomarker for kidney problems. It has also been introduced as a risk factor for atherosclerosis. The classic risk factors for atherosclerosis trigger cellular and humeral immunoreaction in macrophages through induction of heat shock protein expressions and increased levels of GRP94 and HSP70 are associated with increased atherosclerosis risk. The present study evaluated the possible effect(s) of TMAO on the expression of GRP94 and HSP70 at protein levels...

INTRODUCTION: Paediatric fractures are often of good prognosis due to auto-correction of insufficient fracture reduction by bone remodeling. In sub-Saharan Africa, traditional healers are renowned for managing fractures and there is a neglect for specialized pediatric fracture care. We aimed to determine the demographic characteristics, clinical presentation, treatment patterns and outcomes of paediatric fractures in a tertiary health care centre in Yaoundé. METHODS: We conducted a prospective cohort study of all consenting consecutive cases of fractures in patients younger than 16 years managed between January 2011 and June 2015 at the University Teaching Hospital, Cameroon...

Proximal humerus fracture after pectoralis major tendon repair has been recently reported. Although this complication is rare, it may be possible to decrease such risk using newer techniques for myotenodesis. This study was designed to evaluate various unicortical stress risers created at the proximal humeral metadiaphysis during myotenodesis for repair of pectoralis major ruptures. A simulated pectoralis major myotenodesis was performed using fourth-generation Sawbones (N=30). Using previously described anatomic landmarks for the tendinous insertion, 3 repair techniques were compared: bone trough, tenodesis screws, and suture anchors (N=10 each)...

Isolated coronal shear fracture of the trochlea is a rare injury. Isolated fractures of the humeral trochlea have all been reported in adults. We present the case of a 7-year-old boy with pain and swelling of the elbow joint. Magnetic resonance imaging and arthrogram revealed an isolated osteochondral fracture of the trochlea in the coronal plane. Ossification of the trochlea had not yet occurred. An anterior approach was used for reduction and fixation of the fragment. A good clinical outcome was achieved with no signs of bony or chondral necrosis of the fragment 1 year after surgery...

254nm photolyses of bovine serum albumin [BSA] in aqueous solutions, were carried out in the presence of activated carbons modified by reaction with ozone. The photolyses were monitored by fluorescence spectroscopy and UV spectrophotometry, and the products were characterized by elemental analysis, FTIR, TGA, total organic carbon analyses [TOC], and XPS. The ozonation reaction was carried out at room temperature with O3 under dry and wet conditions. The carbon characterization showed that the reaction increased the amount of epoxide and carbonyl groups on the carbon matrix...

INTRODUCTION: The three currently used methods of treatment: namely open reduction plate osteosynthesis (ORPO), Minimally invasive plate osteosynthesis (MIPO), antegrade intramedullary nailing(IMN) are all reported as satisfactory procedures for treatment of humeral shaft fractures. However none of the published reports have a comparison of superiority of one procedure over the other. We evaluated the clinical, radiological and functional outcome of the three procedures. MATERIALS AND METHODS: We studied adult patients with humerus shaft fractures over a period of 2 years from May 2014 to May 2016 in a level 1 trauma center...

Non-union of the humeral shaft is infrequently noticed after surgical fixation. Sixty eight patients whose osteosynthesis of humeral shaft had failed leading to non-union were identified over a duration of 10 years from (January 2006 to December 2015). Clinical and radiographical follow-up was available for 64 patients (4 patients were lost for follow-up), with a mean age of 58 years (range 25-78 years). All patients had aseptic atrophic non-union of either: proximal shaft (n=12), mid shaft (n=38), and lower shaft (n=14)...

Anatomic characterization of the humeral nutrient artery varies among the several textbooks on human anatomy. To clarify the anatomic characteristics of the humeral nutrient artery, we reexamined its origin and course by cadaveric dissection. In typical cases, one prominent nutrient foramen was situated on the anteromedial surface of the humeral shaft, and the nutrient canal distally penetrated the cortical bone layer. The humeral nutrient artery originated from the brachial artery below the level of the nutrient foramen as a short ascending branch...

The brachial plexus is commonly blocked at the interscalene level for shoulder and proximal humeral surgery. There are only a few publications about the interscalene technique in pediatric patients for a peripheral nerve block. Ultrasound-guided peripheral nerve block has become increasingly more popular for pediatric patients because of high success rates and safety concerns. We used ultrasound-guided interscalene brachial plexus block in an 18-month-old child with an acute upper respiratory infection who had a supracondylar fracture of the humerus...

REVIEW
Dilip R Patel, Stephen Breisach
Shoulder pain in young athletes generally is a result of poor sports technique and overuse. A number intrinsic causes of shoulder pain have been identified. Pain may also be referred to shoulder area from cervical spine, neck and chest pathology. Overuse stress injury of the proximal humeral physis is important to recognize early in order to prevent later complications. Shoulder impingement syndrome is a general term used to describe multiple underlying lesions and relatively uncommon in young athletes. In adolescent athletes, glenohumeral instability is an important underlying pathomechanical basis for shoulder pain...
