The best commonly applied approach in seating ergonomics is the concept that the seat must fit the sitter.Understanding of population anthropometry is necessary because, in the mass vehicle market, a single seat should fit a huge portion of the population. This research work proposes some automotive seat fit parameters based on a representative Nigerian anthropometric data, to ensure an optimum fit between the vehicle seats and the occupants, as well as providing adequate accommodation. Anthropometric data of 863 Nigerians captured with special emphasis on the dimensions that are applicable in automotive seat design. A comparison made between the data obtained and that of five other countries. The proposed dimensions includes: seat cushion width (475mm); seat cushion length (394mm); seat height (340mm); seat lateral location (583mm); seat back height (480mm); seat back width (427mm); armrest height (246mm); headrest height (703mm); armrest surface length (345mm); backrest width (thoracic level) (524mm); seat adjustment (186mm); backrest width (lumbar level) (475mm) and distance between armrests (475mm). A comparison made between the proposed dimensions and those recommended by four other scholars for other populations. Finally, an ergonomic automotive seat suitable for the Nigerian population was designed using AutoCAD 2016 software based on the proposed established dimensions

Both anterior and posterior approaches have shown insignificant differences in good clinical outcomes with one over another advantages and disadvantages. This review aimed to provide evidence for the best management of subaxial cervical spine injuries and discuss the clinical outcomes and complications. Clinical studies of anterior versus posterior and anterior versus anterior–posterior (combined) approaches to subaxial cervical spine injury were searched electronically from PubMed, Medline, ScienceDirect, Cochrane Library, and other Internet databases. Clinical improvement, complication rates, and mortality rates showed no significant differences with an odds ratio of 1.09 (95% confidence interval [CI], 0.79–1.49; p=0.61) for the anterior versus posterior approach and an odds ratio of 1.05 (95% CI, 0.35–3.18; p=0.93) for the anterior versus the combined approach. Surgical duration and blood loss were significantly different between the anterior and posterior groups with a mean difference of −42.84 (95% CI, −64.39 to 21.29; p<0.0001); −212.91 (95% CI, −417.60 to 8.22; p=0.04), respectively, whereas the length of hospitalization did not (p=0.16). No difference was found between the groups when compared by clinical improvement and complication rate. Meanwhile, the anterior approach was superior to the posterior approach in terms of surgical duration, blood loss, and hospitalization length.

PURPOSE: Hypertonic fluids such as mannitol and half-molar sodium lactate are given to treat intracranial hypertension in patients with severe traumatic brain injury (TBI). In this study, sodium lactate was compared to mannitol in patients with TBI to investigate the efficacy in reducing intracranial pressure (ICP). METHODS: This study was a systematic review with literature research on articles published in any year in the databases of PubMed, ScienceDirect, Asian Journal of Neurosurgery, and Cochrane Central Register of Controlled Trials. The keywords were "half-molar sodium lactate", "mannitol", "cerebral edema or brain swelling", and "severe traumatic brain injury". The inclusion criteria were (1) studies published in English, (2) randomized control trials or retrospective/prospective studies on TBI patients, and (3) therapies including half-molar sodium lactate and mannitol and (4) sufficient data such as mean difference (MD) and risk ratio (RR). Data analysis was conducted using Review Manager 5.3. RESULTS: From 1499 studies, a total of 8 studies were eligible. Mannitol group reduced ICP of 0.65 times (MD 0.65; p = 0.64) and improved cerebral perfusion pressure of 0.61 times (MD 0.61; p = 0.88), better than the half-molar group of sodium lactate. But the half-molar group of sodium lactate maintained the mean arterial pressure level of 0.86 times, better than the mannitol group (MD 0.86; p = 0.09). CONCLUSION Half-molar sodium lactate is as effective as mannitol in reducing ICP in the early phase of brain injury, superior over mannitol in an extended period. It is able to prevent intracranial hypertension and give better brain tissue perfusion as well as more stable hemodynamics. Blood osmolarity is a concern as it increases serum sodium.

Chopart’s amputations often have better outcome compared to higher level amputation with limb length preservation, larger weight bearing surface, and lower energy demand. Diabetic Charcot arthropathy and severe foot deformity is a treatment challenge. Reconstructive surgery with hindfoot arthrodesis is viable for plantigrade and stable foot, more fitting for orthotic shoe wear. We described a 62-years old male with underlying type 2 diabetes mellitus, presented with infected left diabetic foot ulcer and treated with Chopart’s amputation. Debridement of the Chopart’s stump was done, the wound healed and patient ambulating with a shoe filler. A year later, he noticed a progressive varus deformity of the left ankle following a trivial fall. He was in pain thus unable to bear weight. The hindfoot was in equino-varus deformity with tight Achilles tendon and uncorrectable, leading to left hindfoot fusion. Patient was able to progress to full weight bearing ambulation with no pain post-operatively.
