RESUMEN

BACKGROUND: Implants are commonly used to stabilize proximal femoral osteotomies in children with cerebral palsy (CP). Removal of implants is common practice and believed to avoid infection, fracture, or pain that might be associated with retained hardware. There is little evidence to support a prophylactic strategy over a reactive approach based on symptoms. The aim of this study was to compare the outcomes of prophylactic and reactive approaches to removal of proximal femoral implants in children with CP. METHODS: An intention-to-treat model was used to compare 2 institutions that followed a prophylactic (within ∼1 y) and reactive (following complication/symptoms) approach to hardware removal, respectively. Patients with CP who had femoral implants placed at or before age 16, and had ≥2-year postsurgical follow-up were included. Demographics, surgical details, reasons for removal, and complications were recorded. χ and t tests were used. RESULTS: Six hundred twenty-one patients (prophylactic=302, reactive=319) were followed for an average of 6 years (range, 2 to 17 y). Two hundred eighty-seven (95%) implants were removed in the prophylactic group at 1.2 years. In the reactive group, 64 (20%) implants were removed at an average of 4.2 years. Reasons for removal included pain; infection; fracture; or for repeat reconstruction. The rate of unplanned removals due to fracture or infection was higher in the reactive group (4.7% vs. 0.7%, P=0.002), but there was no difference in the rate of complications during/after removal between the 2 groups (1.7% vs. 3.1%; P=0.616). No specific risk factor associated with unplanned removal could be identified; but children under 8 years old seemed more likely to undergo later removal (odds ratio 1.98; 95% confidence interval, 0.99-3.99). CONCLUSIONS: Eighty percent of patients in the reactive removal strategy avoided surgery. This group did have a 4% higher rate of fracture or infection necessitating unplanned removal but these were successfully treated at time of removal with no difference in complication rates associated with removal between both groups. One would need to remove implants from 25 patients to avoid 1 additional complication, providing some support for a reactive approach to removal of proximal femoral implants in this population. LEVEL OF EVIDENCE: Level III-therapeutic.

RESUMEN

BACKGROUND: The aim of this study was to determine consumers' perspectives on fair allocation of publicly funded in vitro fertilization (IVF) in the recently implemented Ontario Fertility Program (OFP). The research questions were as follows: 1) What factors do those who require IVF think are important to consider when distributing funded IVF? and 2) What are the barriers to accessing publicly funded IVF? METHODS: We approached this qualitative study with a social constructivist interpretative framework with grounded theory methodology. Data were obtained via focus group. We recruited participants eligible for the OFP from a tertiary care fertility clinic. Two researchers conducted all interviews, independently reviewed the transcriptions and analyzed the data for open coding, followed by axial coding and then selective coding to determine themes. RESULTS: A total of 13 participants (10 women and 3 men with an average age of 36.4 [range 28-40.7] yr) partook in 4 focus groups. The average duration of infertility was 1.9 (range 0.4-3) years. Three important domains were identified. First, the procedure of distributing funds should be done in a transparent and consistent manner. Second, everyone should have a fair and equal chance to accessing the funds. Participants suggested a combination of first-come, first-served and a scoring system as a method to distribute funds. Lack of communication, associated costs and stress of experiencing infertility were cited as barriers to accessing publicly funded IVF. INTERPRETATION: Ensuring equal and fair access to funds should be prioritized, and information about the process and distribution method to obtain OFP funding should be clearly provided to patients. Transparency, standardization and better communication should be implemented to uphold procedural justice for patients and reduce emotional stress. The findings may be considered by policy-makers to improve the current OFP and when developing similar programs.

RESUMEN

PURPOSE: Corrective three dimensional (3D) effect of different braces is debatable. We evaluated differences in in-brace radiographic correction comparing a custom thoracic-lumbo-sacral-orthosis (TLSO) (T) brace to a Chêneau type TLSO (C) brace using 3D EOS reconstruction technology. Our primary research question was the 3D effect of brace on the spine and in particularly the apical vertebra rotation (AVR). METHODS: This was a retrospective comparative analysis of patients with adolescent idiopathic scoliosis who had orthogonal AP and lateral X-rays with and without brace. A 3D image of the spine was reconstructed. Coronal, sagittal and axial spine parameters were measured before bracing and then on the first post-brace X-ray. Brace efficacy in controlling coronal, sagittal and axial parameters was evaluated. RESULTS: Eighteen patients treated with the C brace and ten patients treated with the T brace were included. No difference was found regarding patients' age, gender, magnitude of Cobb angle, sagittal parameters or AVR at inclusion. Following bracing, AVR was significantly reduced by the C brace compared to the T brace [average correction of 8.2° vs. 4.9° (P = 0.02)]. Coronal and sagittal correction did not differ significantly between the two groups. CONCLUSIONS: By utilizing a novel 3D reconstruction technology, we were able to demonstrate that braces differ in their immediate effects on the spine. Although clinical relevance should be evaluated in a future trial we feel that the ability to measure treatment effects in 3D, and especially the transverse plane, is an important tool when evaluating different treatments.

RESUMEN

OBJECTIVES: To evaluate the efficacy and postoperative morbidity of a mini-incision vasectomy reversal (MIVR) using no-scalpel vasectomy principles compared with traditional incisional approaches to vasectomy reversal (VR). METHODS: Of 164 patients undergoing consecutive VR, 139 underwent bilateral vasovasostomy (55% bilateral MIVR, 24% mixed MIVR/traditional incision VR, and 21% bilateral traditional incision VR). The MIVRs were performed using a subcentimeter incision after the vas deferens was captured and delivered through the skin using the no-scalpel vasectomy principles and instruments. Semen analyses were obtained at 3-month intervals postoperatively until pregnancy was achieved. Motile sperm in the ejaculate after VR defined patency. Pain and functional recovery after surgery were evaluated using a previously validated 10-point pain scale adapted to VR. The no-scalpel vasectomy patients served as controls for the postoperative pain assessments. RESULTS: The median follow-up was 11.6 months. The patency rate was 96%, 100%, and 91% for the MIVR, mixed MIVR/traditional incision, and bilateral traditional incision VR, respectively (P = .4). The semen parameters did not significantly differ among the VR approaches. The pain severity during the first 48 hours after surgery was significantly less (P < .05) for the patients who had undergone bilateral MIVR than for the patients who had undergone traditional incision VR and did not significantly differ from that of the men who had undergone no-scalpel vasectomy. The patients returned to normal activities an average of 2 days earlier after MIVR than after traditional incision VR. CONCLUSIONS: The results of our study have shown that MIVR does not compromise patency outcomes or semen parameters compared with more traditional approaches to VR and results in less pain during the early period of recovery after surgery and quicker functional recovery.

RESUMEN

Some experts contend that occlusion of the proximal corpora cavernosal bodies of the penis with a tourniquet or manual compression during induction of an artificial erection distorts the penile anatomy and potentially masks proximal curvatures. The current report highlights a rare, but potentially morbid, case of postoperative pulmonary edema as a consequence of rapid fluid injection into the corporal bodies during surgical correction of penile curvature, in a 48-year-old male with a high-risk cardiac history.

RESUMEN

BACKGROUND: On surgical simulators, measures of economy of hand motion have been shown to be reliable, valid, and objective measures of technical competence. Our goal was to validate hand-motion analysis (HMA) as an objective measure of surgical skill on real patients. METHODS: HMA (hand movement frequency, hand travel distance) was evaluated serially on 2 standardized, live patient surgeries (vasectomy, vasectomy reversal) for both a novice and experienced surgeon. HMA parameters were correlated with blinded, case-matched assessments of technical skill using previously validated global rating scales and surgical checklist scores applied to unedited surgical videos. Serial hand-motion data from the novice and experienced surgeon were plotted to establish competency-based learning curves over time. RESULTS: Intraoperative HMA correlated significantly with case-matched global rating and checklist scores. Meaningful improvements in the number of hand movements and hand travel distance were shown over time for the novice surgeon, but remained stable for the experienced surgeon. CONCLUSIONS: Intraoperative assessment of economy of hand motion represents a feasible, objective, and valid measure of technical skill and can be used to establish competency-based surgical learning curves.

RESUMEN

Cardiomyocyte apoptosis is a component of cardiac remodeling that can contribute to heart failure in obesity. A role for leptin in mediating this process has been suggested and the objective of this work was to investigate the effect of leptin on apoptosis and associated mechanisms in H9c2 cells which were subjected to hypoxia/reoxygenation (HR) to mimic myocardial ischemia/reperfusion. Qualitative immunofluorescent and quantitative laser scanning cytometry approaches demonstrated that exposure of cells to HR increased DNA fragmentation (TUNEL staining) which was attenuated by leptin (6 nM, 1 h) pretreatment. We also found increased annexin-V binding and caspase-3 activity in cells exposed to HR, both of which were attenuated by leptin pretreatment. Leptin reduced HR-induced translocation of the pro-apoptotic protein Bax to the mitochondrial membrane, which provides a mechanism to explain its protective effect. Consequently, leptin attenuated the HR-induced decrease in mitochondrial membrane potential and increase in cytochrome c release from mitochondria. Leptin treatment increased the phosphorylation of p38 MAPK and AMPK and respective inhibitors of these kinases, SB203580 and Compound C, prevented the ability of leptin to decrease HR-induced caspase-3 activity. In conclusion, we establish mechanisms via which leptin exerts anti-apoptotic effects that may be of significance in understanding the development of heart failure in obesity.

RESUMEN

Obesity is a known risk factor for induction of myocardial infarction, but, paradoxically, may also confer a protective effect against subsequent remodeling leading to heart failure. In this study, we investigated the effect of leptin, the product of the obese (ob) gene, on cardiomyocyte apoptosis, a well-characterized component of cardiac remodeling after myocardial infarction. Exposing H9c2 cells to H(2)O(2) decreased cell viability, and this was attenuated by pretreating cells with leptin for 1 h, but not 24 h. Leptin also attenuated the ability of H(2)O(2) to increase phosphatidylserine exposure and annexin V binding. Further investigation of underlying mechanisms of leptin's protective effect demonstrated that the H(2)O(2)-induced decrease in mitochondrial membrane potential (Psi) leading to cytochrome c release was attenuated by leptin pretreatment, and this was associated with reduced translocation of the pro-apoptotic Bax protein to the mitochondrial membrane. Finally, leptin prevented H(2)O(2)-induced increases in caspase-3 cleavage and activity, although again 24 h leptin pretreatment did not confer significant protection. In summary, we have demonstrated that acute leptin pretreatment mediates anti-apoptotic effects in H9c2 rat cardiomyocytes, which may be of significance in clarifying the direct impact of leptin on the heart.

RESUMEN

PURPOSE: Oxidative stress is considered a risk factor for prostate cancer development and is associated with the production of reactive oxygen species (ROS). The base excision repair gene MYH protects against ROS-mediated damage to DNA. Inherited MYH mutations predispose to colorectal adenomas and cancer. A compromised base-excision repair function due to defective MYH may contribute to prostate carcinogenesis. Here, we examine the genetic contribution of MYH to prostate cancer risk. METHODS: Patients diagnosed with high-grade prostatic intraepithelial neoplasia (HGPIN) alone (n = 45), prostate cancer alone (n = 123) or both (n = 82) were screened for the two most common mutations in the MYH gene using PCR-based RFLP analysis. A single patient with an inherited MYH mutation as well as a subset of 26 patients presenting with a family history of colorectal cancer were screened for additional MYH mutations by direct sequencing of the entire coding region. RESULTS: Biallelic germline mutations in MYH were not detected among prostate cancer patients. Only a single patient was a heterozygous carrier for the Y165C missense mutation. Allelic deletion or somatic mutation of the remaining MYH allele was not identified in this patient's tumor DNA. Two patients harbored V22M polymorphism and three patients were carriers of Q324H polymorphism. CONCLUSIONS: MYH mutations are unlikely to contribute to prostate cancer risk.
