Atypical Skull-Base Osteomyelitis
Atypical skull-base osteomyelitis is a rare but fatal disease that usually involves infection of the ethmoid, sphenoid, occipital, or temporal bones that form the skull base. Unlike typical (so-called otogenic), atypical skull-base osteomyelitis has no otogenic cause. Instead, some authors call atypical skull-base osteomyelitis sinonasal, since the infection most often originates from the nose and paranasal sinuses.

Mesenchymal Stromal Cell-Based Targeted Therapy Pancreatic Cancer
Pancreatic cancer is an aggressive malignancy with high mortality rates and poor prognoses. Despite rapid progress in the diagnosis and treatment of pancreatic cancer, the efficacy of current therapeutic strategies remains limited. Hence, better alternative therapeutic options for treating pancreatic cancer need to be urgently explored. Mesenchymal stromal cells (MSCs) have recently received much attention as a potential therapy for pancreatic cancer owing to their tumor-homing properties.

Percutaneous Pedicle Screw
In percutaneous pedicle screw (PPS) fixation of the osteoporotic spine, rigid screw fixation obtaining strong stabilization is important for achieving successful treatment outcomes. However, in patients with severe osteoporosis, it is difficult to obtain PPS fixation with sufficient stability. PPS fixation has potential disadvantages with respect to maintaining secure stabilization in comparison to conventional pedicle screw fixation. In PPS fixation, bone grafting to achieve posterior spine fusion is generally not applicable and transverse connectors between the rods cannot be used to reinforce the fixation. Various augmentation methods, including additional hooks, sublaminar bands, and hydroxyapatite (HA) sticks, are available for conventional pedicle screw fixation.

Metabolic Bariatric Surgery
Despite worldwide public attention and intense medical efforts, the prevalence of severe morbid obesity in children and adolescents is still rising. Similar to adults, excess adipose tissue triggers multiple immunological and metabolic pathways leading to serious co-morbidities such as impaired glucose tolerance or even type 2 diabetes (T2D), dyslipidemia, arterial hypertension, non-alcoholic fatty liver disease, and hyperuricemia. The management of severe childhood obesity requires a life-long multidisciplinary approach with a combination of lifestyle changes, nutrition, and medications. Standardized life-style intervention programs remain the first-line treatment for morbid obese children and adolescents, but unfortunately reveal limited long-term success. In such cases, metabolic bariatric surgery (MBS) has evolved from being a controversial issue to being included in distinct recommendations.

Hybrid Breast Reconstruction
Lipofilling is a commonly performed procedure worldwide for breast augmentation and correction of breast contour deformities. In breast reconstruction, fat grafting has been used as a single reconstructive technique, as well as in combination with other procedures.

Forefoot Function after Hallux Valgus Surgery
The load integrals (impulse) over the central metatarsal region significantly increased, indicating that surgeries increased the risk of transfer metatarsalgia. There is no solid evidence that hallux valgus (HV) surgeries could improve forefoot functions from a biomechanical point perspective. Surgeries might reduce the plantar load over the hallux and adversely affect push-off function.

Esophagogastric Cancer Surgery
Esophagogastric cancer is among the most common malignancies worldwide. Surgery with or without neoadjuvant therapy is the only potentially curative treatment option. Although esophagogastric resections remain associated with major surgical trauma and significant postoperative morbidity. Prehabilitation has emerged as a novel strategy to improve clinical outcomes by optimizing physical and psychological status before major surgery through exercise and nutritional and psychological interventions.

Artificial Intelligence for Surgeons
Computer vision (CV) is a field of artificial intelligence (AI) that deals with the automatic analysis of videos and images. Recent advances in AI and CV methods coupled with the growing availability of surgical videos of minimally invasive procedures have led to the development of AI-based algorithms to improve surgical care.
