ABSTRACT
PURPOSE: Reconstruction of the anterior cruciate ligament (ACL) is the most frequently performed reconstructive surgery in the knee. Biomechanical studies have shown that double bundle (DB) reconstruction is better than single bundle (SB) reconstruction with regard to rotational stability. It is postulated that resection of ACL fibres that remain in continuity may be counterproductive for the knee as these fibres have the capacity to produce collagen. In this study, we aimed to evaluate the efficacy among selective bundle, DB and SB ACL reconstructions over a 2-year post-operative follow-up period. METHODS: A retrospective comparative study was conducted for comparison between selective bundle, DB and SB reconstructions. Between 2012 and 2014, 291 ACL reconstructions were performed. Of these, 68 patients had selective ACL reconstructions (group SLB), 147 had DB ACL reconstructions (group DB) and 76 had SB ACL reconstructions (group SB). Institutional Review Board approval was obtained, and all patients provided informed consent. Clinical results were assessed with the International Knee Documentation Committee (IKDC), Lysholm and Tegner scores. Stability was measured using Lachman, pivot shift and anterior drawer stress tests using the KT1000 at 30° of knee flexion. RESULTS: There was no significant difference in ligament grade, function grade, IKDC grade, as well as Tegner and Lysholm means among all three groups after a 2-year follow-up period. CONCLUSION: Selective bundle reconstruction provides comparable results to DB and SB reconstruction techniques. It is a viable alternative for patients with partial tears.

This is a case report of a 4-month-old full-term, fully breastfed boy who presented with a persistent periorificial and groin rash associated with poor weight gain and irritability. His serum zinc level was low. The mother's breast milk zinc level was found to be low despite her serum zinc levels being normal, confirming the diagnosis of transient neonatal zinc deficiency. Mutational analysis revealed a novel mutation in the mother's SLC30A2 gene, which encodes a zinc transporter expressed in mammary gland epithelial cells.

Hydroa vacciniforme is a photosensitivity disorder characterized by the childhood onset of necrotic vesiculopapules on exposed areas. We present a case of a 10-year-old boy with a 1-year history of papular lesions over his face. In this report, we discuss the in-depth histology of hydroa vacciniforme, and the management options.
