AI Article Synopsis
- Craniocervical instability due to conditions like tumor destruction of the C-1 lateral mass is difficult to treat.
- The authors detail two cases treated with a one-stage occipitoaxial spinal interarticular stabilization (OASIS) technique, which involved using titanium cages and posterior occipitocervical instrumentation to stabilize the junction.
- The OASIS technique successfully allowed for tumor removal, reconstruction of the C-1 lateral mass, and stabilization, while preserving the vertebral artery, making it a viable option for specific C-1 lateral mass instability cases.
Article Abstract
The treatment of craniocervical instability caused by diverse conditions remains challenging. Different techniques have been described to stabilize the craniocervical junction. The authors present 2 cases in which tumoral destruction of the C-1 lateral mass caused craniocervical instability. A one-stage occipitoaxial spinal interarticular stabilization (OASIS) technique with titanium cages and posterior occipitocervical instrumentation was used to reconstruct the C-1 lateral mass and stabilize the craniocervical junction. The ipsilateral vertebral artery was preserved. The OASIS technique offers single-stage tumor resection, C-1 lateral mass reconstruction, and stabilization with a loadsharing construct. It could be an option in the treatment of select cases of C-1 lateral mass failure.

Background: Paragangliomas are rare neoplasms arising from extra-adrenal chromaffin cells, with mediastinal paragangliomas representing an exceptionally rare subset. This report details the surgical management of a complex mediastinal paraganglioma case, presenting with refractory hypertension and invasion of critical surrounding structures. A comprehensive review of the current literature is included to underscore existing cases, enhance clinical awareness, and share our insights and experience in the diagnosis and treatment of this challenging condition.

There are differing opinions in the literature regarding the cardiovascular safety of long-term methylphenidate use. Studies suggest that the drug may increase the risk of hypertension, myocardial infarction, ventricular arrhythmia, sudden cardiac death, cardiomyopathy, heart failure (HF), pulmonary hypertension, and stroke.

In vertebrates, skeletal muscle comprises fast and slow fibers. Slow and fast muscle cells in fish are spatially segregated; slow muscle cells are located only in a superficial region, and comprise a small fraction of the total muscle cell mass. Slow muscles support low-speed, low-force movements, while fast muscles are responsible for high-speed, high-force movements.

The aim of this study was to quantify the training effects of wearing calf-loaded wearable resistance (WR) during a netball specific warm-up in female netball athletes. Twenty-nine high school female netball athletes were matched for change of direction (COD) speed and randomly allocated to either WR training or an unloaded group. Both groups performed the same warm-up two times per week for 6 weeks, with the WR group wearing 1%-1.

Background: The deep inferior epigastric perforator (DIEP) flap is currently the gold standard for autologous breast reconstruction. In cases where the DIEP is contraindicated, the profunda artery perforator (PAP) flap is now the preferred second-line option in our institution. The PAP flap poses unique challenges to the reconstructive surgeon, especially in Asian women with low body mass index (BMI).
