OBJECTIVES/HYPOTHESIS: We previously reported that high-volume hospital head and neck cancer (HNCA) surgical care is associated with decreased mortality, largely explained by reduced rates of failure to rescue. Frailty is an independent predictor of mortality, but is significantly less likely in patients receiving high-volume care. We investigate whether differences in frailty rates explain the relationship between volume and outcomes in HNCA patients and whether frailty confounds the relationship between failure to rescue and mortality...

OBJECTIVE: Patient-controlled oral analgesia has gained popularity in postoperative pain management. Anesthesia and surgery delay gastrointestinal tract function and this may therefore decrease bioavailability of drugs taken by mouth. To hasten absorption, an orodispersible ibuprofen tablet has been developed. In this study, we evaluated the pharmacokinetics and feasibility of orodispersible ibuprofen tablets in spine surgery patients. METHODS: The study design was a prospective clinical trial where each patient served as her/his own control...

The restoration of normal function and esthetic appearance with a dental prosthesis is a major challenge in the rehabilitation of patients who have lost their teeth and surrounding bone because of surgery for oral cyst or tumor. Rehabilitation with fixed or removable prosthesis is even more challenging when the edentulous span is long and the ridge is defective. Anatomic deformities and unfavorable biomechanics encountered in the region of resection add to the misery. In such situation, a fixed-removable prosthesis allows favorable biomechanical stress distribution along with restoration of esthetics, phonetics, comfort, hygiene, and better postoperative care and maintenance...

BACKGROUND: Marginal zone lymphomas (MZLs) are indolent disorders composed of 3 subtypes: extranodal marginal zone lymphoma (MALT), splenic marginal zone lymphoma (SMZL), and nodal marginal zone lymphoma (NMZL). Early-stage MALT is treated with radiotherapy or antibiotics, and advanced MALT and NMZL are managed with either watch and wait or chemotherapy. SMZLs are treated with splenectomy or rituximab. However, because these approaches have failed to cure patients with SMZL and NMZL, we have systematically used upfront chemotherapy for them, as well as for advanced MALT...

BACKGROUND: Despite recent advances, infection remains the most common etiology of arthroplasty failure. Recent work suggests that 25-hydroxyvitamin D (25D) deficiency correlates with the frequency of periprosthetic joint infection (PJI). We endeavored to examine whether 25D3 deficiency leads to increased bacterial burden in vivo in an established mouse model of PJI and, if so, whether this effect can be reversed by preoperative 25D3 supplementation. METHODS: Mice (lys-EGFP) possessing fluorescent neutrophils were fed a vitamin D3-sufficient (n = 20) or deficient (n = 40) diet for 6 weeks...

Neuroinflammation and Alzheimer's-related pathology play essential roles in postoperative cognitive dysfunction (POCD). High-mobility group box 1 (HMGB1) is well known as a pivotal mediator in neuroinflammation, and its associations with Alzheimer's-related pathology and POCD have been also revealed. Glycyrrhizin is a nature inhibitor of HMGB1 and is reported with neuroprotective effects through oral administration. Therefore, the present study aims to test the hypothesis that the oral pretreatment of glycyrrhizin prevents POCD by inhibiting HMGB1-induced neuroinflammation and Alzheimer's-related pathology in aged mice...

This is a report of an atypical presentation of pyoderma gangrenosum (PG) in a 26-year-old male who had a negative septic screen. The patient had a life-threatening presentation requiring an intensive care unit (ICU) admission for vasopressor support. It was thought that the likely cause of circulatory collapse was an overwhelming cytokine reaction or systemic inflammatory response syndrome (SIRS) secondary to extensive PG lesions rather than septic shock. The patient presented with multiple large ulcers, the largest being 4 cm in diameter on the central chest...
