Introduction: Sexual health concerns are common and significantly impact quality of life, but many people do not seek treatment due to embarrassment and other barriers. A biopsychosocial model of assessment and treatment acknowledges the biological, psychological, and social contributors to sexual difficulties and suggests that all these domains should be evaluated.

Objectives: This paper provides an overview of the major psychological factors contributing to sexual difficulties and offer an evidence-based approach for primary care clinicians to assess and treat these issues.

Article Synopsis
  • The study aimed to gather insights from international experts on the efficacy and challenges of two minimally invasive surgical techniques, transoral laser microsurgery (TLM) and transoral robotic surgery (TORS), for treating supraglottic laryngeal tumors.
  • A survey was conducted with 27 head and neck surgeons, finding that TLM generally took less setup time compared to TORS, although both techniques faced concerns about bleeding during surgery, particularly with TLM.
  • Experts viewed TLM and TORS as largely equal in effectiveness, but noted that TORS offered better control over bleeding and improved visibility during the procedure.

Objectives: The management of the facial nerve (FN) is a major issue in parotid cancer, especially when there is no preoperative facial palsy and FN invasion is discovered intraoperatively. The aim of this study was to assess the impact of FN resection in patients with parotid cancer abutting the FN, without pretreatment facial palsy, using a propensity score matching.

Materials And Methods: Data from all patients treated between 2009 and 2020 for a primary parotid cancer abutting or invading the FN but without pretreatment facial palsy were extracted from the national multicentric REFCOR database.

Article Synopsis
  • Myosin-7A (Myo7A) is a critical motor protein that helps organize stereocilia in inner ear hair cells, playing a key role in hearing.
  • Mutations in Myo7A are linked to various genetic hearing loss conditions, particularly autosomal dominant DFNA11 deafness, but the structural aspects governing its motor functions are not fully understood.
  • This study used cultured kidney cells to identify mutations that enhance Myo7A's targeting to cell surfaces, showing that specific IQ motifs in its structure are crucial for this process, and confirming that some DFNA11 mutations may lead to increased targeting, contributing to the genetics of this hearing loss.

Article Synopsis
  • Salivary carcinomas of minor salivary glands, particularly in the tongue, are rare tumors that may require surgery and/or (chemo-)radiotherapy for treatment.
  • A study involving 103 patients diagnosed between 2009 and 2018 found that the most common types were adenoid cystic and mucoepidermoid carcinomas, with surgery being the primary treatment for most cases.
  • Results indicated that 5-year overall survival was 84.7%, while event-free survival was lower at 38.6%; nonsurgical treatment, alcohol use, and tumor location negatively impacted event-free survival, while nodal positivity was a key factor affecting overall survival.

The role of eculizumab in treating Shiga-toxin-producing (STEC) hemolytic uremic syndrome (HUS) patients with neurological involvement remains unclear. We describe two distinctly different STEC-HUS patients with neurologic involvement successfully managed with eculizumab, and perform a literature review of all published cases. Both patients had complete resolution of neurological symptoms after initiation of eculizumab.

The current benchmark for tongue reconstruction after excision of locally advanced tumors involves the use of free skin or fasciocutaneous flaps, such as the anterolateral thigh flap or forearm free flap. They facilitate the volumetric reconstruction of the tongue, leveraging passive mobility from the remaining native tongue tissue. The challenge in tongue reconstruction surgery remains achieving functional restoration through adequate volume and optimized mobility, using tissue that is both adapted and comparable to native tissue.

Transporting epithelial cells of the gut and kidney interact with their luminal environment through a densely packed collection of apical microvilli known as a brush border (BB). Proper brush border assembly depends on the intermicrovillar adhesion complex (IMAC), a protocadherin-based adhesion complex found at the distal tips of microvilli that mediates adhesion between neighboring protrusions to promote their organized packing. Loss of the IMAC adhesion molecule Cadherin-related family member 5 (CDHR5) results in significant brush border defects, though the functional properties of this protocadherin have not been thoroughly explored.

During deposition, modification, and etching of thin films and nanomaterials in reactive plasmas, many active species can interact with the sample simultaneously. This includes reactive neutrals formed by fragmentation of the feed gas, positive ions, and electrons generated by electron-impact ionization of the feed gas and fragments, excited states (in particular, long-lived metastable species), and photons produced by spontaneous de-excitation of excited atoms and molecules. Notably, some of these species can be transiently present during the different phases of plasma processing, such as etching of thin layer deposition.

Article Synopsis
  • The study addresses the challenges of diagnosing head and neck (HN) squamous dysplasias and carcinomas, particularly the variability in grading these lesions, which remains an issue for many pathologists despite updated grading systems.
  • Researchers developed a deep learning model trained on a large dataset of over 2000 histological samples to assist pathologists in classifying HN lesions based on the 2022 WHO classification system.
  • The model showed high accuracy in classification and introduced a confidence score to help identify reliable predictions, suggesting it could effectively reduce variability in diagnosis and support the integration of AI tools in pathology.
