Preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement and publication bias.
Publication bias is a major problem in evidence based medicine. As well as positive outcome studies being preferentially published or followed by full text publication authors are also more likely to publish positive results in English-language journals. This unequal distribution of trials leads to a selection bias in evidence l level studies, like systematic reviews, meta-analysis or health technology assessments followed by a systematic failure of interpretation and in clinical decisions. ⋯ For systematic reviews/meta-analysis the PRISMA-statement (formerly known as QUOROM) is recommended, as it gives the reader for a better understanding of the selection process. In the future the use of trial registration for minimizing publication bias, mechanisms to allow easier access to the scientific literature and improvement in the peer review process are recommended to overcome publication bias. The use of checklists like PRISMA is likely to improve the reporting quality of a systematic review and provides substantial transparency in the selection process of papers in a systematic review.

Case ReportsElusive penetrating foreign body to the neck causing partial epiglottic airway obstruction.
We present a case of a penetrating foreign body to the neck, which was difficult to detect, causing partial epiglottic and laryngeal outlet airway obstruction, and subsequent intubation challenges. A systematic approach with rapid access to contrast enhanced CT scanning allowed successful airway and haemorrhage control, removal of a wooden stake from the patient's neck, initially undetected at primary and secondary assessments.

Comparative StudyOsteoporosis influences the early period of the healing after distraction osteogenesis in a rat osteoporotic model.
Despite the clinical adoption of distraction osteogenesis (DO), studies examining the bone healing process at the distraction gap in osteoporotic bone are limited. We examined the effect of osteoporosis in the ovariectomized rat on DO. ⋯ Bone turnover with osteoclast predominance in ovariectomized rats is likely to be the cause of a reduction in new bone formation at the distraction gap.

Review Case ReportsCongenital infiltrating lipomatosis of the face: report of three cases and review of the literature.
Three new cases of hemifacial hypertrophy caused by congenital infiltrating lipomatosis of the face are reported. The literature on infiltrating lipomatosis of the face is reviewed with an emphasis on accompanying anomalies and treatment strategies. ⋯ Described first by Slavin and colleagues in 1989, Facial infiltrating lipomatosis is a rare congenital disorder in which mature lipocytes invade adjacent tissue. The phenotypic features include soft-tissue and skeletal hypertrophy, premature dental eruption, and regional macrodontia. Due to its diffuse infiltration and involvement of important facial structures, complete surgical excision is often impossible. The aetiology, natural history, optimal management, and relationship to other disorders of fatty overgrowth are unclear. Because surgical removal of the mass is usually unsuccessful, specific management of this condition will require insight into its pathogenesis.

Case ReportsPost-transfer flap expansion for management of severe post-burn contraction neck.
We report a case of a 35-year-old woman who presented with post-burn neck scar contracture with massive scarring of the neck and lower face. The initial step was to release the contracture with excision of the scar tissue together with coverage of the resultant defect with a latissmus dorsi musculocutaneous flap. Six months later, we implanted a round tissue expander underneath the flap with steady cautious expansion over the following 7 months to almost double the original flap dimensions to achieve an additional replacement of the scar tissue over the upper neck and lower face.
