IMPORTANCE Although it has been previously reported that the transition of extremely low-birth-weight survivors (Յ1000 g) in their mid-20s was similar to that of normal-birth-weight controls (>2500g), there was uncertainty as to whether this positive pattern would persist. OBJECTIVE To compare the social functioning of low-birth-weight prematurely born adults aged 29 to 36 years with that of normal-birth-weight term controls.

Background and Purpose:Total hip arthroplasty (THA) is a safe and reliable surgical procedure. However, THA also has intra- and postoperative complications. A dreaded and frustrating intraoperative complication during total hip arthroplasty is dislocation of the femoral trial head from the neck into the pelvis.Methods:Here, we report on the case of a 71-year old female patient with osteoarthritis of the left hip. Total hip arthroplasty was performed in a lateral position through a standard posterior approach. During intraoperative trial reduction, the femoral trial head dissociated from the taper and dislocated into the psoas compartment. Several unsuccessful attempts, including an additional ventral approach, were made to immediately retrieve the femoral trial head.Results and interpretation:Postoperative a Computerized Tomography (CT) was performed to locate the trial head, a secondary explorative laparotomy was undertaken to retrieve it. The retrieval of the femoral trial head should be performed in a planned second surgical procedure to avoid possible complications during the manipulation necessary for retrieval.

Background and purpose — Substantial bone loss in revision total knee arthroplasty (TKA) is a challenging problem. We studied whether impaction bone grafting provides long-term restoration of bone stock in the treatment of major bone defects in revision surgery of rotational and hinged knee arthroplasties (LINK Endo-Model).Patients and methods — Between 1996 and 2006, 29 knees in 29 patients underwent revision procedures of rotational and hinged knee arthroplasties using impaction bone grafting (IBG) to reconstruct major bone defects. At the latest follow-up, the clinical examination included the Knee Society score (KSS), standardized radiographs, and a questionnaire for the WOMAC score.Results — After a mean follow-up of 10 (6–13) years, 14 knees with 19 IBG reconstructions (5 total, 9 partial revisions) had failed. 12 knees were treated with re-revision surgery mean 5 (1–12) years after the first revision, due to mechanical failure and aseptic loosening of the components. In all these failed cases, the surgeon observed a lack of incorporation with bone graft resorption in the femur or tibia during the re-revision procedure. In all 15 knees that were not re-revised, with 21 reconstructions (6 total, 9 partial revisions), an improvement in the combined KSS score (knee score + function score) of 60 points (p < 0.001) was found at the latest follow-up. In 12 of these knees, a clear incorporation with no visible radiolucent lines around the component and no sign of substantial graft resorption was noted, while unclear radiographic graft incorporation was seen in 3 knees.Interpretation — Our results clearly indicate that IBG alone is not a methodologically sound technique in the revision of rotational and hinged knee arthroplasties.

Research demonstrates that parents’ emotion-related discourse during reminiscing shapes children’s psychosocial outcomes, yet little is known about how different forms of parental emotion-related discourse work in combination. The present study takes a person-centered approach to better understand the relation of multiple forms of parental emotion discourse during reminiscing with problem behaviors in early childhood, as well as child influences on parents’ emotion discourse during reminiscing. Specifically, we simultaneously examine three forms of parents’ emotion-related discourse (emotion coaching and dismissing, emotion explanations, and elaboration) using cluster analysis to determine parents’ patterns of these three discourse forms during discussion about past events. Parents and their preschool-aged children (n = 154) completed a parent–child reminiscing task. Transcripts were coded for emotion coaching and dismissing, emotion explanations, and elaboration. Parents reported on children’s internalizing and externalizing behaviors, temperament, and gender, and children completed a language assessment. Cluster analyses revealed three parental discourse patterns: elaboration/negative emotion emphasis, positive and negative emotion emphasis, and low emotion discourse. Children’s receptive language was associated with parents’ membership in the low emotion discourse cluster. Children’s temperament and gender were unrelated to parental emotion-related discourse patterns. Parents in the positive and negative emotion emphasis cluster had children with fewer internalizing behaviors compared to both other clusters, and parents in the elaboration/negative emotion emphasis cluster had children with more internalizing behaviors compared to both other clusters. Findings support the utility of a person-centered approach in providing a holistic view of parents’ use of multiple emotion socialization strategies during reminiscing.
