Osteosarcoma (OS) is the most common primary malignancy of bone and patients with metastatic disease or recurrences continue to have very poor outcomes. Unfortunately, little prognostic improvement has been generated from the last 20 years of research and a new perspective is warranted. OS is extremely heterogeneous in both its origins and manifestations. Although multiple associations have been made between the development of osteosarcoma and race, gender, age, various genomic alterations, and exposure situations among others, the etiology remains unclear and controversial...

T Verse, B A Stuck
Uvulopalatopharyngoplasty (UPPP) was first described in 1964 with regard to surgical treatment of snoring and in 1981 with regard to treatment of obstructive sleep apnea (OSA). The initial surgical techniques for OSA were very invasive, frequently leading to significant morbidity and complications. Wolfgang Pirsig et al. were the first in Germany to recognize that a radical surgical technique increased only the complications, not the efficacy of UPPP. The less invasive surgical technique developed based on these findings is still established in Germany...

Mehdi Shirazi, Ali Ariafar, Amir Hossein Babaei, Abdosamad Ashrafzadeh, Ali Adib
BACKGROUND: Urethrocutaneous fistula (UCF) is the most prevalent complication after hypospadias repair surgery. Many methods have been developed for UCF correction, and the best technique for UCF repair is determined based on the size, location, and number of fistulas, as well as the status of the surrounding skin. OBJECTIVES: In this study, we introduced and evaluated a simple method for UCF correction after tubularized incised plate (TIP) repair. METHODS: This clinical study was conducted on children with UCFs ≤ 4 mm that developed after TIP surgery for hypospadias repair...

Minimally invasive surgery has been replacing the open standard technique in several procedures. Similar or even better postoperative outcomes have been described in laparoscopic or robot-assisted procedures when compared to open surgery. Moreover, minimally invasive surgery has been providing less postoperative pain, shorter hospitalization, and thus a faster return to daily activities. However, the learning curve required to obtain laparoscopic expertise has been a barrier in laparoscopic spreading. Laparoscopic surgery training laboratory has been developed to aid surgeons to overcome the challenging learning curve...

REVIEW
Abdel-Ghani Azzouqa, James P Stevenson
Malignant pleural mesothelioma is an uncommon and aggressive thoracic malignancy that is rarely curable, even when multimodality therapy is used. Systemic chemotherapy is the primary treatment for the majority of patients with this disease; however, surgical resection may benefit a subset of patients with early-stage disease. The surgical approach that offers the best outcomes remains an area of controversy, with data from retrospective comparisons being the only guide. Historically, extrapleural pneumonectomy (EPP) has been the standard procedure, carrying with it a cost of significant morbidity and impact on quality of life that has raised questions regarding its routine application...

PURPOSE: Chronic maxillary atelectasis is characterized by unilateral spontaneous enophthalmos and hypoglobus due to increased orbital volume secondary to maxillary sinus inward deformation. Reformation of the sinus architecture and reconstruction of the orbit are key to a successful outcome. Here, we introduce a one-staged surgery that addresses both these goals. PATIENTS AND METHODS: We retrospectively reviewed 11 patients treated with one-stage orbital and sinus surgery...

A man aged 28 years, with neurofibromatosis type 1, presented with abdominal pain and visible right lower chest swelling. He had cutaneous neurofibromas and several café-au-lait spots. CT scan of the chest and abdomen revealed a giant mass most likely originating from the right 7th intercostal nerve, extending downwards into the abdomen causing massive hepatic compression. A Trucut biopsy showed malignant peripheral nerve sheath tumour. Radical surgical resection with wide margins was performed. The chest wall and diaphragm were reconstructed with improvised surgical technique with excellent results...

BACKGROUND: The function of the anterolateral capsule of the knee has not been clearly defined. However, the contribution of this region of the capsule to knee stability in comparison with other anterolateral structures can be determined by the relative force that each structure carries during loading of the knee. PURPOSE/HYPOTHESIS: The purpose of this study was to determine the forces in the anterolateral structures of the intact and anterior cruciate ligament (ACL)-deficient knee in response to an anterior tibial load and internal tibial torque...

With the recent development of two effective treatments for patients with idiopathic pulmonary fibrosis, an accurate diagnosis is crucial. The traditional approach to diagnosis emphasises the importance of thorough clinical and laboratory evaluations to exclude secondary causes of disease. High-resolution CT is a critical initial diagnostic test and acts as a tool to identify patients who should undergo surgical lung biopsy to secure a definitive histological diagnosis of usual interstitial pneumonia pattern...

BACKGROUND AND PURPOSE: Small infants with biliary atresia and hypoplastic portal veins (PV) are at risk for portal vein thrombosis (PVT) after liver transplantation (LT), which can lead to graft loss and mortality. Extra-anatomical PV reconstruction techniques have been established for adult cases of PVT; however, they have not been widely accepted for infants. METHODS: Here, we report the successful use of an extra-anatomical meso-portal venous jump graft to treat early PVT after LT in a 6-month-old infant with biliary atresia and PV hypoplasia...

BACKGROUND: Many surgical procedures can produce persistent lymphorrhea, lymphoceles, and lymphedema after lymph node and lymph vessel damage. Appropriate visualization of the lymphatic system is challenging. Indocyanine green (ICG) is a well-known nontoxic dye for lymphatic flow evaluation. ICG fluorescence-guided lymphography has emerged as a promising technique for intraoperative lymphatic mapping. OBJECTIVE: Our goal was to develop a high spatial resolution, real-time intraoperative imaging technique to avoid or recognize early deep lymphatic vessel damage...

BACKGROUND: The training of surgeons that perform renal transplantations can be diverse. For example, the training profile can vary greatly, involving urologists to general surgeons. The efficacy of training programs directed at transplantation surgeons is influenced by numerous factors, including the specialist profile who is trained, the number of procedures available to trainees in a given teaching hospital, and the duration of training. Here we determine the number of procedures necessary to consolidate and contribute to proficiency in renal transplantation technique...
