Abstract
In the literature, first metatarsophalangeal joint arthrodesis with lesser metatarsal head resection seems to be a reliable procedure in rheumatoid foot deformity. Maybe this procedure could be proposed in nonrheumatoid severe forefoot deformity (hallux valgus angle >40° and lesser metatarsophalangeal dislocation). The aim of this study was to compare radiological and clinical outcomes between lesser metatarsal head resection and lesser metatarsal head osteotomy in nonrheumatoid patients. Thirty-nine patients (56 feet) suffering from well-defined nonrheumatoid severe forefoot deformity were retrospectively enrolled in our institution between 2009 and 2015. Metatarsal head resection and metatarsal head osteotomy represented 13 patients (20 feet) and 26 patients (36 feet), respectively. In this observational study, a rheumatoid population (21 patients) was included as the control. The clinical outcome measures consisted of American Orthopaedic Foot and Ankle Society score, Foot and Ankle Ability Measurement, and Short Form-36. The radiological outcomes were: intermetatarsal angle, hallux valgus angle, and metatarsophalangeal alignment. Mean follow-up was 24 months. Satisfaction rate was, respectively, 92% for resection, 91% for osteotomy procedure, and 80% for surgery in rheumatoid patients. Short Form-36 global score was, respectively, 80.7 (52.5-96.4), 76 (57.7-93), and 68.3 (22.6-86). No functional outcome difference was found between resection and osteotomy procedures, except that the metatarsal head resection group had poorer results in sports activities than the osteotomy group. Complications were similar between osteotomy and resection (p > .05). The radiological outcomes were improved significantly from preoperative to postoperative. First metatarsophalangeal joint arthrodesis with lesser metatarsal head resection in nonrheumatoid severe forefoot deformity might be a good therapeutic option.

Abstract
PURPOSE The need for a period of non-weight bearing after medial opening wedge high tibial osteotomy remains controversial. It is hypothesized that immediate weight bearing after medial opening wedge high tibial osteotomy would have no difference in functional scores at one year compared to delayed weight bearing. METHODS Fifty patients, median age 54 years (range 40-65), with medial compartment osteoarthritis, underwent a medial opening wedge high tibial osteotomy utilizing a locking plate without bone grafting. Patients were randomized into an Immediate or a Delayed (2 months) weight bearing group. All patients were assessed at one-year follow-up and the two groups compared. The primary outcome measure was the IKS score. Secondary outcome measures included the IKDC score, the VAS pain score and rate of complications. RESULTS The functional scores significantly improved in both groups. The IKS score increased from 142 ± 31 to 171 ± 26 in the Immediate group (p < 0.001) and from 148 ± 22 to 178 ± 23 in the Delayed group (p < 0.001). The IKDC score increased from 49 ± 17 pre-operatively to 68 ± 14 one-year post-operatively in the Immediate group (p < 0.0001) and from 44 ± 16 to 69 ± 19 in the Delayed group (p < 0.001). The average VAS for pain 2 months after surgery was 3 ± 3 in the Immediate group and 3 ± 2 in the Delayed (n.s.). There was no significant difference between the two groups in any of the outcome measures. The mean mechanical femorotibial angle changed from 6° of varus (0°-15° of varus, SD = 3°) to 4° of valgus (5°-11° of valgus, SD = 3°) in the Immediate group and from 5° of varus (0°-10° of varus, SD = 3°) to 3° of valgus (2° of varus to 8° of valgus, SD = 3°) in the Delayed group. No difference was seen between groups, and no loss of correction was observed in any patient. Two cases of non-union occurred, one in each group. One infection and one deep vein thrombosis occurred in the Immediate group. CONCLUSION Immediate weight bearing after medial opening wedge high tibial osteotomy had no effect on functional scores at 1 year follow-up and did not significantly increase the complication rate. Immediate weight bearing after medial opening wedge high tibial osteotomy appears to be safe and can allow some patients a quicker return to activities of daily living and a decreased convalescence period. LEVEL OF EVIDENCE II.

Abstract
PURPOSE To analyze the relationship between the cervical spine and global spinal-pelvic alignment in young patients with idiopathic scoliosis based on a morphological classification, and to postulate the hypothesis that cervical kyphosis is a part of cervico-thoracic kyphosis in them. METHODS 120 young patients with idiopathic scoliosis were recruited retrospectively between 2006 and 2011. The following values were measured and calculated: cervical angles (CA), cervico-thoracic angles (CTA), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), spinal sacral angle (SSA), hip to C7/hip to sacrum, thoracic kyphosis (TK), lumbar lordosis (LL), Roussouly sagittal classification, Lenke Type Curve and Lumbar Modifier. The cervical curves were classified as lordosis, straight, sigmoid and kyphosis. They were categorized into four groups as cervical non-kyphosis group (CNK Group), cervical kyphosis group (CK Group), cervical-middle-thoracic kyphosis group (CMTK Group), and cervical-lower-thoracic kyphosis group (CLTK Group) according to their morphological characters of sagittal alignments. All parameters were compared and analyzed among groups. RESULTS The incidence of cervical kyphosis was 40 % (48/120). The CA and the CTA were in significant correlation (r = 0.854, P = 0.00). The cervical spine alignments were revealed to be significantly different among groups (r = 85.04, P = 0.00). Significant differences among groups in CA, CTA and TK were also detected. A strong correlation between the group type and Lenke Lumbar Modifier was still seen (P < 0.05). Fisher's exact test revealed that the individual vertebral body kyphosis and wedging were directly related to the overall cervical kyphosis (P = 0.00, respectively). CONCLUSION The cervical kyphosis is correlated with global sagittal alignment, and is a part of cervico-thoracic sagittal deformity in young patients with idiopathic scoliosis. Despite the deformity in cervical alignment, the global spine could still be well-balanced with spontaneous adjustment. The correlation between our grouping based on the morphological characteristics of the sagittal alignments and Lenke Lumbar Modifier suggests that the coupled motion principle be appropriate to explain the modifications both in coronal and sagittal planes.

Abstract
In order to contribute to higher levels of job satisfaction, job involvement and productivity, a match or fit should be established between the dominant career anchor associated with a specific occupation and that of the employee. A career anchor is an individual's set of self-perceived talents, abilities, motives, needs and values that form the nucleus of one's occupational self-concept. Psychologists have always been part of the service orientated careers and therefore one would expect that it is likely that their dominant career anchor would be service orientation. If this is the case, psychologists with service as their dominant career anchor are supposed to have greater job satisfaction and job involvement compared to those with different career anchors. However, according to literature, this assumption is not necessarily correct. The primary goals of the current study were to determine whether in fact service is the dominant career anchor of psychologists in the Free State and whether there are significant differences regarding job satisfaction and job involvement between psychologists with and without service as their dominant career anchor. A third goal was to determine whether psychologists with different dominant career anchors differ significantly from one another regarding job satisfaction and job involvement. Questionnaires measuring career orientations, job satisfaction and job involvement were sent to 165 of the 171 registered psychologists in the Free State region. Only 75 psychologists (45,5%) responded which exceeded the traditional return rate of 20 to 30%. Due to the small sample of respondents, a nonparametric statistical test, namely the Mann Whitney U test was conducted to determine possible differences. An analysis of the data showed that 21 respondents had entrepreneurship as their dominant career orientation while 12 fell in the technical/functional, 12 in the challenging, 9 in the service and 8 in the autonomy categories of dominant career anchors. No significant differences regarding job satisfaction between psychologists with and without service as dominant career orientation could be determined. Both groups experienced a fairly high degree of job satisfaction and a higher level of intrinsic job satisfaction occurred compared to extrinsic job satisfaction. A significant difference between the two groups in terms of job involvement occurred. Psychologists with service as dominant career orientation showed a higher level of job involvement, although the degree of job involvement for both groups was fairly low. No significant differences regarding job satisfaction and job involvement among psychologists with different career orientations could be found.

Abstract
This study evaluated the influence of Westernised and traditional African diets on biochemical and haematological profiles in vervet monkeys (Cercopithecus aethiops). Twelve adult male vervet monkeys bred at the Medical Research Council, all over 4 years of age and weighing more than 5 kg each, were divided into two groups of six individuals. These monkeys were raised on a standard in-house diet post-weaning, before they were fed for 8 weeks on diets containing milk solids (17.2%) or maize + legume (17.4%), as sources of high crude protein (+/- 3.5 g/kg). High protein diets had no significant effect on serum biochemical indices such as aspartate aminotransferase (AST) and gamma glutamyl transferase (GGT) concentrations (P > 0.10). However, alanine aminotransferase (ALT) concentrations were significantly higher during week 8 (P < 0.05) for the maize + legume protein group. Alkaline phosphatase (ALP; P < 0.07), total protein (P < 0.0001), albumin (P < 0.02), and bilirubin (P < 0.003) were elevated in the milk solids group, while glucose levels were also significantly higher for the milk solids group (P < 0.05) between weeks 2 and 6. Elevated protein intake had no significant effect on haematological parameters such as red blood cells (RBC), platelet and white blood cell (WBC) counts, haemoglobin levels and monocyte and neutrophil concentrations (P > 0.10). In contrast, serum lymphocyte levels were significantly raised in the maize + legume protein group (P = 0.03), whereas values for the haematocrit (P < 0.002), mean cell volume (MCV; P < 0.03) and mean corpuscular haemoglobin concentration (MCHC; P < 0.0001) were higher in the monkeys that were fed the milk solids. This investigation showed that the type of dietary protein that is consumed may well affect certain biochemical and haematological indices in vervet monkeys. Compared to the group that were given the traditional African food regime, the animals on the Western-type milk solids diet showed significant elevations in a number of important biological indicators. However, longer-term studies should be completed in this area if we are to make firmer conclusions regarding the link between the nature of dietary proteins that are consumed and its effect on metabolism.
