Article Synopsis
- Trigger finger can cause pain and hinder daily activities, leading to a search for less invasive treatment options due to complications from traditional surgery.
- An experimental study on cadavers compared three treatments: a new device, ultrasound-guided technique, and a percutaneous needle method, focusing on the effectiveness of A1 pulley release and safety concerning surrounding structures.
- The new device and ultrasound methods achieved complete A1 pulley release in 100% of cases, while the needle method only succeeded 38% of the time, with the new device showing less damage to flexor tendons and no neurovascular injuries, making it a safer alternative for treating trigger finger.
Article Synopsis
- The study assessed the effectiveness of hypertonic saline as a treatment for dorsal synovial cysts in the wrist.
- 50 patients were treated with hypertonic saline after cyst aspiration and followed for 24 weeks to measure outcomes like pain, strength, and recurrence.
- Results showed that 39.1% of cysts resolved, while 60.9% recurred, with complications like pain and edema noted but no significant changes in strength or motion.
Objective: To verify the prevalence of patients who were victims of motorcycle trauma who were under the influence of alcohol and drugs.
Methods: The study was observational and prospective, with patients hospitalized to the Orthopedics and Traumatology Ward of Hospital São Paulo (UNIFESP), from March 2015 to March 2016. The study included patients of all genders, over 18 years old, hospitalized due to motorcycle trauma and who needed orthopedic surgical treatment.
Objective: To evaluate the cure rate for dorsal synovial cysts of the wrist with aspiration and percutaneous sclerotherapy using 75% hypertonic glucose.
Methods: We enrolled 45 patients older than 18 years with untreated dorsal synovial cysts of the wrist. They underwent percutaneous aspiration and sclerotherapy with 75% hypertonic glucose 75%.
Aortoesophageal fistulas are uncommon, dreadful vascular events, most frequently found in the setting of thoracic aorta aneurysms. Patients usually present with thoracic pain, dysphagia and sentinel hematemesis - the Chiari triad - followed by life threatening hematemesis. Emergent open surgery with debridement of necrotic tissue and in situ aortic graft repair is currently the best strategy.

We present the case of a 70-year-old man with an ulcerated well-circumscribed polypoid submucosal mass in the gastric antrum which was proven to be a glomus tumor. CT showed progressive contrast enhancement.

We tested the effects of these chemicals on the gills and liver of both male and female guppies using qualitative and quantitative histopathological analyses associated with histopathological condition indexes. Both genders showed similar median lethal concentration (LC ) at 96 h for GLY (68.
