Avascular necrosis (AVN) of the talus is 1 of the most difficult foot and ankle pathologies to diagnose and manage. The purpose of this study was to report on the functional outcomes of 3D-printed total talus replacement (TTR) in 2 patients with talar AVN who both underwent a failed revascularization.

Patients with advanced nasopharyngeal carcinoma (ANC) often experience chronic pain. Opioids are generally recommended to treat tumor-related pain, but increased opioid use may lead to detrimental aftereffects, particularly with respect to tumor progression, resulting in reduced quality of life and increased risk of death. Our objective was to investigate whether the high size of opioid prescriptions is associated with poor overall survival (OS) in patients with ANC.

With >700 transplant surgeries performed each year, Toronto General Hospital (TGH) is currently one of the largest adult transplant centers in North America. There is a lack of literature regarding both the identification and management of chronic postsurgical pain (CPSP) after organ transplantation. Since 2014, the TGH Transitional Pain Service (TPS) has helped manage patients who developed CPSP after solid organ transplantation (SOT), including heart, lung, liver, and renal transplants.

To observe the effect of electroacupuncture (EA) on pain behavior, synovial inflammatory response and demyelination of saphenous nerve in the rats modeled with knee osteoarthritis (KOA) and explore the effect mechanism of EA for reliving allodynia.

Children with Klippel-Trenaunay syndrome have vascular malformations, varicosities at unusual distribution, and unilateral soft and skeletal tissue hypertrophy of the lower extremity. Corrective surgery of the deformity is necessary to improve gait and wear acceptable footwear. Perioperative pain relief for debulking of the right great toe in a known case of KTS with sciatic hemangioma was achieved with ultrasound-guided sciatic nerve block in an avascular area.

Nuclear protein in testis (NUT) carcinoma is a rare aggressive malignant epithelial cell tumor, previously known as NUT midline carcinoma (NMC), characterized by an acquired rearrangement of the gene encoding NUT on chromosome 15q14. Due to the lack of characteristic pathological features, it is often underdiagnosed and misdiagnosed. A variety of methods can be used to diagnose NMC, including immunohistochemistry, karyotyping, fluorescence in situ hybridization, reverse transcription-polymerase chain reaction, and next-generation sequencing. So far, there is no standard treatment plan for NMC and the prognosis is poor, related to its rapid progression, easy recurrence, and unsatisfactory treatment outcome.

Risk stratification tools exist for patients presenting with chest pain to the emergency room and have achieved the recommended negative predictive value (NPV) of 99%. However, due to low positive predictive value (PPV), current stratification tools result in unwarranted investigations such as serial laboratory tests and cardiac stress tests (CSTs).

Since Kambin experimentally induced arthroscopy to treat herniated nucleus pulposus, percutaneous endoscopic lumbar discectomy (PELD) has been developed. The branch of the segmental artery around the neural foramen may be damaged during PELD using the transforaminal approach. We report 2 rare cases in which segmental artery injury that occurred during PELD was treated with emergency embolization.

Phlegmonous gastritis (PG) is a rare bacterial infection of the gastric submucosa and is related to septicemia, direct gastric mucosal injury, or the direct influence of infection or inflammation in neighboring organs. Here, we present a patient who had spontaneous biloma caused by choledocholithiasis and then PG resulting from bile leakage after biloma drainage.
