The diagnosis of abdominal pain in emergency departments is challenging, and appendicitis is a common concern. Atypical symptoms often delay diagnosis. Although the Alvarado score aids in decision-making, its low specificity can lead to unnecessary surgeries. ⋯ The gradient boosting algorithm achieved a sensitivity, specificity, and accuracy of 89.74%, 95.90%, and 94.41%, respectively. The support vector classifier demonstrated a sensitivity of 89.74%, specificity of 92.62%, and accuracy of 91.93%. The use of modern machine learning methods aids in the accurate diagnosis of appendicitis.

SH is considered to be the most common benign tumor within the human spine. 1-2% of SH get symptomatic with back pain in most cases. Less often, ingrowth of vessels into the spinal canal is seen. In these cases, more invasive surgical treatment is required. Recurrence of SH following surgical treatment is a very rare condition. ⋯ Thus, radical excision, sufficient stabilization and fusion is considered to be an adequate treatment concept for recurrent SH.
