Background: To compare clinical and functional outcomes of different reconstructive options for a hypopharyngeal defect after head and neck cancer surgery.

Methods: We retrospectively analyzed 127 cases who had undergone hypopharyngeal reconstruction, as either pedicled (25 cases), fasciocutaneous free flap (FCFF) (41 cases) or visceral flap (61 cases).

Results: Overall incidence of flap compromise was 10.2% (13 cases), and there were no statistically significant factors associated with flap compromise. Fistula or stenosis occurred in 36.2% (46 patients) and 23.6% (30 patients), respectively. Salvage surgery increased the risk of fistula formation (OR 2.93, 95% CI 1.32-6.52, p < 0.01), whereas FCFF showed a protective effect for stenosis, compared to pedicled flap (OR 0.09, 95% CI 0.01-0.47, p < 0.01).

Conclusion: Outcomes of hypopharynx reconstruction can be successful if different flap options are used appropriately according to the type of defect and previous treatment history of the patient.

Chronic pain is a pervasive and debilitating condition with increasing implications for public health, affecting millions of individuals worldwide. Despite its high prevalence, the underlying neural mechanisms and pathophysiology remain only partly understood. Since its introduction 35 years ago, brain diffusion magnetic resonance imaging (MRI) has emerged as a powerful tool to investigate changes in white matter microstructure and connectivity associated with chronic pain.

Cognition relies on transforming sensory inputs into a generalizable understanding of the world. Mirror neurons have been proposed to underlie this process, mapping visual representations of others' actions and sensations onto neurons that mediate our own, providing a conduit for understanding. However, this theory has limitations.

Postnatal establishment of enteric metabolic, host-microbial and immune homeostasis is the result of precisely timed and tightly regulated developmental and adaptive processes. Here, we show that infection with the invasive enteropathogen Typhimurium results in accelerated maturation of the neonatal epithelium with premature appearance of antimicrobial, metabolic, developmental, and regenerative features of the adult tissue. Using conditional Myd88-deficient mice, we identify the critical contribution of immune cell-derived mediators.

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive sarcomas and the primary cause of mortality in patients with neurofibromatosis type 1 (NF1). These malignancies develop within preexisting benign lesions called plexiform neurofibromas (PNs). PNs are solely driven by biallelic loss eliciting RAS pathway activation, and they respond favorably to MEK inhibitor therapy.

Recurrent missense mutations in the human epidermal growth factor receptor 2 (HER2) have been identified across various human cancers. Among these mutations, the active S310F mutation in the HER2 extracellular domain stands out as not only oncogenic but also confers resistance to pertuzumab, an antibody drug widely used in clinical cancer therapy, by impeding its binding. In this study, we have successfully employed computational-aided rational design to undertake directed evolution of pertuzumab, resulting in the creation of an evolved pertuzumab variant named Ptz-SA.
