Prevention Strategies in Obesity Management: A Systematic Review Comparing Canadian and American Guidelines for Adults.

The fast-increasing obesity prevalence rates in children, youths, and adults in the last decade have made obesity prevention a global public health priority. The primary objective of this study is to evaluate the various obesity prevention strategies and guidelines implemented in the United States and Canada. Thus, for this study, a systematic review was performed on various online databases including PubMed, Scopus, Google Scholar, and MEDLINE.

Grade 3 Proximal Humerus Giant Cell Tumour: Is Resection and Reconstruction with Prosthesis a Valuable Option?

Grade 3 proximal humerus giant cell tumours are uncommon and the results of their surgical management with prosthetic replacement are not well established. We retrospectively studied patients with grade 3 giant cell tumours of proximal humerus treated with excision and prosthetic replacement from January 2009 and December 2018. We identified 13 patients who underwent tumour excision and prosthetic replacement.

Special AT-rich sequence-binding protein 2 (SATB2) in the differential diagnosis of osteogenic and non-osteogenic bone and soft tissue tumors.

Background: The diagnosis of osteosarcoma (OSA) depends on clinicopathological and radiological correlation. A biopsy is considered the gold standard for OSA diagnosis. However, since OSA is a great histological mimicker, diagnostic challenges exist.

The results of patellar stainless steel wire extensor mechanism reconstruction in proximal tibial tumour excision mega-prosthesis surgeries for proximal tibial sarcomas.

Background: Extensor mechanism function after a proximal tibial tumour excision is the major determining factor for the limb function. However, problems of extensor lag, delayed healing and poor functional outcomes exist with the previous methods of its reconstruction. We describe a novel technique of using a patellar stainless steel (SS) wire to reconstruct the extensor apparatus of the knee in non-porous coated implants and examine the functional outcome and associated complications.

Foot and Ankle Giant Cell Tumors Are Not so Aggressive After All: A Retrospective Study.

Giant cell tumors are most commonly seen around the knee and rarely around the foot and ankle. Therefore there is a paucity of data regarding the options of surgery, outcomes and recurrence of Giant cell tumors involving the foot and ankle. We retrospectively studied patients with Giant cell tumors of the foot and ankle from January 2009 to December 2017.

HEALTH ASSESSMENT OF FREE-RANGING CHELONIANS IN AN URBAN SECTION OF THE BRONX RIVER, NEW YORK, USA.

The Bronx River in Bronx, New York, US spans an area of significant human development and has been subject to historic and ongoing industrial contamination. We evaluated the health of freeranging native common snapping turtles ( Chelydra serpentina) and nonnative invasive red-eared sliders ( Trachemys scripta) in a segment of the Bronx River between May and July 2012. In 18 snapping turtles and nine sliders, complete physical examinations were performed, ectoparasites collected, and blood was analyzed for contaminants (mercury, thallium, cadmium, arsenic, lead, selenium, oxychlordane, alpha-chlordane, dieldrin, DDD, DDE, polychlorinated biphenyls).

Time required for effective action of phenol against giant cell tumour cells.

Purpose: To evaluate the time required for effective action of phenol against the giant cell tumour (GCT) cells.

Methods: Fresh GCT cells were harvested from 9 patients with primary GCT of the distal femur (n=4), proximal tibia (n=4), and proximal humerus (n=1), with the Campanacci tumour grades 3 (n=6), 2 (n=2), and 1 (n=1). Specimens were immersed in 80 % phenol for one, 3, 6, and 10 minutes, and were assessed by a single pathologist for irreversible cell death and the depth of phenol penetration.

Indices affecting outcome of neglected femoral neck fractures after valgus intertrochanteric osteotomy.

Objectives: To evaluate preoperative neck resorption and postoperative valgus orientation as predictors of union and functional outcome after valgus intertrochanteric osteotomy for treatment of neglected femoral neck fractures and nonunions.

Design: Retrospective cohort study.

Setting: Tertiary care center.

Experience of using local flaps to cover open lower limb injuries at an Indian trauma center.

Background: Optimal care of open, high-velocity, lower limb injury requires surgical skills in debridement, skeletal stabilization, and in providing appropriate soft tissue cover. Timely coordination between orthopedic and plastic surgeons, though ideal, is often difficult. In our center, orthopedic surgeons undertake comprehensive treatment of open fractures including soft tissue cover.

Long-term outcome of high-energy open Lisfranc injuries: a retrospective study.

Background: The outcome of open Lisfranc injuries has been reported infrequently. Should these injuries be managed as closed injuries and is their outcome different?

Methods: We undertook a retrospective study of high-energy, open Lisfranc injuries treated between 1999 and 2005. The types of dislocation, the associated injuries to the same foot, the radiologic and functional outcome, and the complications were studied.

Reconstruction of open contaminated achilles tendon injuries with soft tissue loss.

Background: Open achilles tendon injuries, present a complex problem to the treating surgeon especially if associated with tendon and soft tissue loss. We present eight such patients treated with tendon repair/reconstruction and reverse flow sural artery flap for soft tissue cover.

Patients: Eight patients (age, 12-64 years) with a spectrum of open tendo-achilles injuries of acute and chronic (infected), including loss of tendon of up to 10 cm, tendon defects with no distal attachment and one with partial loss of the calcaneum were treated between November 2005 and July 2006.

Reconstruction of complete knee extensor mechanism loss with gastrocnemius flaps.

Unlabelled: We assessed the outcome after reconstruction of traumatic, complete, infected, extensor mechanism loss attributable to high-velocity open knee injuries in eight consecutive patients (all males) who presented to us between February 2005 and September 2007 at an average followup of 24 months. All were treated with gastrocnemius flaps. The loss in extensor mechanism was the patellar tendon in five patients, patella and patellar tendon in two patients, and combined patella, quadriceps, and patellar tendon in one patient.

Open infected Achilles tendon injury--reconstruction of tendon with fascia lata graft and soft tissue cover with a reverse flow sural flap.

We present a patient with an open, infected Achilles tendon injury with a soft tissue defect of 12 cm x 5 cm and a tendon defect of 10 cm. He underwent a two-stage procedure. A first stage debridement of tendon and soft tissue was followed by a second stage tendo Achilles reconstruction using fascia lata graft and soft tissue cover with a reverse flow sural flap.

Ranavirus infection of free-ranging and captive box turtles and tortoises in the United States.

Iridoviruses of the genus Ranavirus are well known for causing mass mortality events of fish and amphibians with sporadic reports of infection in reptiles. This article describes five instances of Ranavirus infection in chelonians between 2003 and 2005 in Georgia, Florida, New York, and Pennsylvania, USA. Affected species included captive Burmese star tortoises (Geochelone platynota), a free-ranging gopher tortoise (Gopherus polyphemus), free-ranging eastern box turtles (Terrapene carolina carolina), and a Florida box turtle (Terrepene carolina bauri).

Protecting a patellar ligament reconstruction after proximal tibial resection: a simplified approach.

Unlabelled: Limb salvage in tumor surgery has encouraged the development of megaprostheses. However, reattaching the ligamentum patellae poses a particular problem: avulsion and/or extensor lag may lead to poor function. We describe a new technique of patellar ligament reconstruction.

Successful repair of chronic instability of anterior chest wall following right parasternal approach for closure of atrial septal defect in a young female.

Chronic instability of anterior chest wall is a known complication following the minimally invasive right parasternal approach for valvular heart operations. The exact incidence of this condition, as well as the need for reoperation, has not been well documented. We report the first case of successful correction of unstable anterior chest wall in a 33-year-old lady after she underwent atrial septal defect closure through right paramedian approach eight years ago.
