Background. Experience from treating patients with Spanish influenza and A(H5N1) suggested that convalescent plasma therapy might be beneficial. However, its efficacy in severe pandemic A(H1N1) 2009 virus (H1N1 2009) infection remained unknown. Methods. During the period 1 September through 30 June 2010, we conducted a prospective cohort study by recruiting aged ≥18 years H1N1 requiring intensive care. Patients were offered treatment neutralizing antibody titer of ≥1:160, harvested apheresis...
Background. Infections caused by the pandemic H1N1 2009 influenza virus range from mild upper respiratory tract syndromes to fatal diseases. However, studies comparing virological and immunological profile of different clinical severity are lacking. Methods. We conducted a retrospective cohort study 74 patients with infection, including 23 who either developed acute distress syndrome (ARDS) or died (ARDS-death group), 14 desaturation requiring oxygen supplementation survived without ARDS...
Humans are one of the few species undergoing an adolescent growth spurt. Because children enter spurt at different ages making age a poor maturity measure, longitudinal studies necessary to identify patterns and commonalities in growth. The standard determinant, peak height velocity (PHV) timing, is difficult estimate individuals due diurnal, postural, measurement variation. Using prospective populations healthy from two North American populations, we compared timing spurt's normalized...
Objective: We describe the first successful penis transplant in United States a patient with history of subtotal penectomy for penile cancer. Background: Penis transplantation represents new paradigm restoring anatomic appearance, urine conduit, and sexual function after genitourinary tissue loss. To date, only 2 transplants have been performed worldwide. Methods: After institutional review board approval, extensive medical, surgical, radiological evaluations were performed. His candidacy...
Background: No published study has ever described the relationship of medial patellofemoral ligament (MPFL) attachment to distal femoral physis in skeletally immature cadaveric specimens. As such, there continues be much confusion about this relationship, which is important when considering MPFL reconstruction patient. Hypothesis: The footprint border physis. Study Design: Descriptive laboratory study. Methods: Sixteen specimens were used for average age was 12 years (range, 10-15 years)....
Background: It has been proposed that the epiphyseal tubercle on inferior surface of capital femoral epiphysis may be responsible for clinical distinction between a stable and an unstable slipped (SCFE). The anatomy its relationship to lateral vessels have not previously rigorously defined. Methods: Twenty-two cadaveric epiphyses from donors who had three seventeen years age were analyzed then digitized with use high-resolution laser scanner. height, location, approximate area measured...
Tibial torsion and femoral anteversion are common rotational abnormalities in children, their courses most often benign self-resolving. Although neither usually requires surgical treatment, the decision to perform a derotational osteotomy is based on degree of functional impairment. Neither condition thought influence development osteoarthritis hip or knee; however, date there have been no large scale studies confirming this.Tibial version 1158 cadaveric tibiae femora were measured using...
Understanding skeletal maturity is important in the management of idiopathic scoliosis. Iliac apophysis, triradiate cartilage, hand, and calcaneal ossification patterns have previously been described to assess both peak height velocity (PHV) percent growth remaining; however, these markers may not be present on standard spine radiographs. The purpose this study was describe a novel assessment method based proximal humeral epiphyseal patterns.Ninety-four children were followed at least...
Anatomic surgical reconstruction of the medial patellofemoral ligament (MPFL) has been popularized for treatment recurrent patellar instability in skeletally immature population. Previous anatomic studies have found that femoral attachment point MPFL is very close to distal physis.To establish safe angles drilling epiphysis graft placement.Descriptive laboratory study.A total 23 cadaveric epiphyses were scanned into high-resolution 3-dimensional images. Using computer-aided design, we...
The recently described Modified Fels wrist skeletal maturity system (mFels SMS) allows for accurate estimation using a single anteroposterior radiograph but requires evaluation of 8 parameters. A faster method may have clinical utility in the outpatient setting. radiographic parameters comprising mFels SMS were analyzed 80 children. Segmented linear regression and generalized estimating equation (GEE) analyses used to identify subsets most important different patient demographics parameter...
Introduction In 2019, Centers for Medicare and Medicaid Services (CMS) mandated hospitals to provide publicly available chargemasters aid in transparency of pricing hospital procedures. Despite the mandate, many orthopedic do not comply with CMS guidelines. The goals this study are (1) assess compliance top 50 U.S. children's mandate (2) analyze variation common procedures among these hospitals. Methods pediatric within United States were selected based on News World Report. Fifteen then...
In Brief Study Design. A prospective study comparing supine bending, push-prone, and traction under general anesthesia (UGA) radiographs in adolescent idiopathic scoliosis. Objective. To compare the effectiveness of 3 different flexibility methods on structural nonstructural main thoracic (MT) thoracolumbar/lumbar (TL/L) curves. Summary Background Data. Supine side bending are major method for determining curve reducibility. Push-prone show compensatory curves same radiograph, but have not...
Background: Ossification of the calcaneal apophysis has never been fully characterized. We examined ossification sequence calcaneus in relation to iliac and timing peak height velocity (PHV). Methods: Ninety-four healthy children (forty-nine girls forty-five boys), from three eighteen years old, were followed longitudinally through growth with annual serial radiographs physical examinations. These done at least annually ten fifteen age. The PHV was calculated using measurements each child....
Participation of women in medicine has increased markedly recent decades, but gender disparities still exist, particularly academic medicine. To provide insight into the gap, specifically orthopaedic sports medicine, we investigated relationship between and authorship literature from 1972 to 2018.Information about every original article four prominent journals 2018 was extracted PubMed. The proportions female first, second, middle, senior authors over time were determined. Gender influences...
The ability to estimate skeletal maturity using a knee radiograph would be useful in anterior cruciate ligament (ACL) injuries and limb-length discrepancy immature patients. Currently, quick, accurate, reproducible method is lacking.Serial radiographs made 3 years before 2 following the chronologic age associated with 90% of final height (an enhanced gold standard compared peak velocity) were analyzed 78 children. Pyle Hoerr (PH) was simplified by developing discrete stages for distal part...
Background: Cast room procedures, such as cast application and removal, pin suture removal can cause significant anxiety in young children. The use of music therapy the to decrease has not been previously reported. Methods: We performed a randomized, prospective study soft lullaby compared with no 69 children 10 years or younger undergoing procedures. Heart rates (beats per minute) were recorded waiting using pulse oximeter. Results: A total 28 randomized 41 music. mean rise heart rate...
Background: Occasionally, a bone graft or comminuted fracture fragment is dropped on the operating-room floor and becomes contaminated. The purpose of this study was to determine an optimal method for sterilizing with minimum sacrifice cell viability. Methods: A set discarded samples taken from series twenty total knee arthroplasty operations. were uniformly contaminated use bacterial broth prepared culture floor. in each underwent five different decontamination procedures. Specifically, one...
