Management and functional outcomes of a pipkin type II fracture: A case report.

Introduction: Femoral head (Pipkin) fractures are rare injuries typically caused by high-energy trauma. Classified into four types, their management remains debated, particularly for Pipkin type II fractures. This case report provides insights into surgical treatment, rehabilitation, and associated complications.

Relapse of Diffuse Large B-Cell Lymphoma as Painless Masses in the Abdominal Wall Muscles: A Rare Case Report.

Background: The most frequent type of non-Hodgkin lymphoma (NHL) is diffuse large B-cell lymphoma (DLBCL). Although lymph nodes are the most commonly affected organs compromising 70% of DLBCLs, only 5% of extranodal lymphomas represent skeletal muscle involvement. Specifically, abdominal wall muscle involvement is rare and there are only a few reported cases of DLBCL with this type of muscle involvement.

Mature mediastinal teratoma with adhesions to the pericardium: A rare case report.

Key Clinical Message: Mature mediastinal teratoma (MMT) is a benign tumor that is composed of well-differentiated tissues from all three germ cell layers. Malignant tumors have a distinct feature of adhering to the surrounding organs. Therefore, adhesion of MMT to the adjacent tissues, as a benign tumor, is rare and considered a surgical challenge.

Adipofascial anterolateral thigh free flap in head and neck reconstruction: a case series.

Background: The adipofascial anterolateral thigh (AF-ALT) free flap represents a versatile technique in head and neck reconstructions, with its applications increasingly broadening. The objective was to detail the novel utilization of the AF-ALT flap in orbital and skull base reconstruction, along with salvage laryngectomy onlay in our case series.

Method: We conducted a retrospective analysis at Roswell Park Comprehensive Cancer Center, spanning from July 2019 to June 2023, focusing on patient demographics and reconstructive parameters data.

Comparing the Outcomes of Osteocutaneous Radial Forearm and Fibula Free Flaps in the Reconstruction of Mandibular Osteoradionecrosis.

Background: This study compares the outcomes of osteocutaneous radial forearm free flap (OC-RFFF) and fibula free flap (FFF) reconstruction of mandibular osteoradionecrosis (ORN).

Methods: Retrospective review of patients undergoing OC-RFFF/FFF reconstruction for mandible ORN between 2005 and 2020 at a tertiary center. Patient characteristics, postoperative complications, and functional outcomes were evaluated using chi-squared and logistic regression analysis.

Metabolic and Aging Influence on Anticancer Immunity in Oral Cancer.

The average age and obesity prevalence are increasing globally. Both aging and metabolic disease burden increase the risk of oral squamous cell carcinoma (OSCC) through profound effects on the immunological and metabolic characteristics within the OSCC tumor microenvironment. While the mechanisms that link aging and obesity to OSCC remain unclear, there is evidence that the antitumor responses are diminished in both conditions.

Association of low adherence to weekly cisplatin with outcomes in patients with head and neck squamous cell carcinoma: a retrospective cohort study.

Background: The National Comprehensive Cancer Network (NCCN) guideline recommends consideration of weekly cisplatin as an alternative option for patients with head and neck cancer undergoing definitive chemoradiation. However, in a recent phase III trial (ConCERT), 20% of patients treated with weekly cisplatin could not receive a total of 200 mg/m, and the association of low adherence to weekly cisplatin and cancer control outcomes remains unclear. To fill this knowledge gap, we performed an observational cohort study of patients with head and neck cancer undergoing definitive chemoradiation with weekly cisplatin.

Immediate Free Fibula Flap After Maxillectomy With Simultaneous Full-arch Dental Implant-Supported Prosthetic Rehabilitation of the Midface and Mandible: The "Super Reconstruction Concept".

Immediate reconstruction and dental rehabilitation for ablative defects of the head and neck in one surgery is now a commonly used technique among reconstructive surgeons. Often patients are edentulous or partially edentulous in the jaw opposing that with pathology. In this case, only rehabilitating the dental arch affected by pathology would not render the patient with a functional occlusion.

Role of Angular Interface Sign in Characterizing Small Exophytic Renal Masses in Computed Tomography; Prospective Study.

The widespread use of computed tomography (CT) has increased the incidence of small renal cell masses. We aimed to evaluate the usefulness of the angular interface sign (ice cream cone sign) to differentiate a broad spectrum of small renal masses using CT. The prospective study included CT images of patients with exophytic renal masses ≤ 4 cm in maximal dimension.

Association of Body Mass Index With Outcomes Among Patients With Head and Neck Cancer Treated With Chemoradiotherapy.

Importance: Combined modality therapy, such as chemoradiotherapy, often results in significant morbidity among patients with head and neck cancer. Although the role of body mass index (BMI) varies based on cancer subtypes, its association with treatment response, tumor recurrence, and survival outcomes among patients with head and neck cancer remains unclear.

Objective: To evaluate the role of BMI in treatment response, tumor recurrence, and survival outcomes among patients with head and neck cancer undergoing chemoradiotherapy.

The effects of surface treatments on electron beam melted Ti-6Al-4V disks on osteogenesis of human mesenchymal stromal cells.

Additive manufactured (AM) Titanium-6Aluminum-4Vanadium (Ti64) scaffolds display unique mechanical and biological properties for implant devices. The elastic modulus can be tailored by adjusting the porosity, further facilitating bone ingrowth. Although Ti64 implants are biocompatible, the effects of AM surfaces without porous structures, and how the topography and surface chemistry of the respective surfaces affect the osteogenesis of bone marrow-derived mesenchymal stromal cells (BMSCs) has not yet been revealed.

Evaluation of Selective Tibial Neurotomy for the Spastic Foot Treatment Using a Personal Goal-Centered Approach: A 1-Year Cohort Study.

Background: Selective tibial neurotomy (STN) has already demonstrated its effectiveness to reduce foot deformities and spasticity, but assessment according to a goal-centered approach is missing.

Objective: To evaluate the effectiveness of STN associated with a postoperative rehabilitation program for the treatment of the spastic foot, according to a goal-centered approach.

Methods: Interventional study (before-after STN and rehabilitation program) with observational design including consecutive adult patients with spastic foot, who received STN followed by a rehabilitation program, was performed.

Pathogenesis and progression of anosmia and dysgeusia during the COVID-19 pandemic.

Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) is the causative agent of COVID-19 which was detected in late 2019 in Wuhan, China. As of September 2022, there have been over 612 million confirmed cases of COVID-19 with over 6.5 million associated deaths.

Usefulness of ultrasound fusion technology for hepatocellular carcinoma localisation, pre- and post-thermal ablation.

Introduction: Percutaneous thermal ablation of inconspicuous lesions can be challenging. Fusion ultrasound (FUS) allows the use of previously performed diagnostic imaging like computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET-CT) to localise hepatocellular carcinoma (HCC) for treatment. This paper illustrates FUS case studies of pre-, intra- and post-ablation imaging of inconspicuous HCC, supplemented by use of contrast-enhanced ultrasound (CEUS).

Injection laryngoplasty during transoral laser microsurgery for early glottic cancer: a randomized controlled trial.

Background: Transoral laser microsurgery is widely used for treating T1/T2 glottic cancers. Hyaluronic acid (HA) is commonly used in vocal cord augmentation. We investigated the impact of intra-operative injection laryngoplasty on voice outcomes in early glottic cancer.
