History A 31-year-old woman with a history of bilateral orthotopic lung transplantation performed 10 months earlier for cystic fibrosis presented for a routine follow-up appointment, with her chief symptom being a cough. The cough started approximately 1 month prior to this appointment and was minimally productive of clear to yellow phlegm. In addition to her cough, she reported increased sinus congestion and a sensation of "something in her upper chest." She denied shortness of breath, wheezing, hemoptysis, or cigarette smoking...

BACKGROUND: Staphylococcus aureus is the most commonly isolated bacterium from patients with surgically recalcitrant chronic rhinosinusitis (CRS). Understanding the immune responses to S aureus biofilms will provide insights into how the host response may be manipulated by therapeutic agents to improve the chances of successfully preventing and treating these infections. In this study, we investigated the inflammatory immune response in a rabbit model of S aureus biofilm-related sinusitis by analyzing the levels of some major inflammatory cytokines...

PURPOSE: Polyether-ether-ketone (PEEK) implants have become increasingly popular for use in reconstructive procedures. It is imperative to understand the consequences of using this biomaterial in anatomic sites that can pose a risk of infection. Specifically, the use of PEEK in paranasal sinus cavity reconstruction is not well documented. This study examined postoperative complications, namely surgical site infection and implant loss, in patients who underwent paranasal sinus cavity reconstruction using PEEK implants...

Lymphatic vessels remove and transport excess interstitial fluid to lymph nodes (LNs) for fluid balance and immune protection. LNs are typically surrounded by perinodal adipose tissue (PAT). However, PAT is a blood vessel-rich but lymphatic-rare tissue; therefore, how excess fluid in PAT is removed remains unclear. Using C57BL/6 mice, fluorescent dye tracing and transmission electron microscopy results suggest that fluid in PAT can travel to the LN via collagen I+ channels (PAT-LN conduits), merge into a collagen-rich space between the PAT and LN capsule (PAT-LN sinus), and may enter the LN via the LN capsule-associated conduits...

BACKGROUND: Asymptomatic pharyngeal colonization by potential bacteria is the primary reservoir for bacterial species within a population and is considered a prerequisite for development of major childhood diseases such as sinusitis, otitis media, pneumonia, bacteremia, and meningitis. However, there is dearth of data on the colonization and drug resistance pattern of the main bacterial pathogens in the pharynx of HIV infected children in Ethiopia. Therefore, this study determined the pharyngeal colonization and drug resistance profile of bacterial pathogens in HIV infected children attending ART clinic of Felegehiwot Referral Hospital (FHRH), Amhara Region, Ethiopia...

Septic cavernous sinus thrombosis (SCST) is an uncommon consequence of head and face infection, but a rare complication after craniofacial fracture. In this case, SCST developed in a 13-year-old girl following a minor fall during volleyball, with impact and resulting abrasive contusion of the left forehead. She developed watery rhinorrhea, progressive headache, fever, nausea, vomiting, and left proptosis with blurred vision, and was admitted to hospital 3 days after injury. Drowsiness, high-grade fever, severe headache, left ocular pain with marked periorbital swelling, and paralysis of extraocular eye movements developed...

Staphylococcus aureus is a skin- and respiratory tract-colonizing bacterium and is the leading cause of community-acquired skin infections. Dissemination of these bacteria into systemic circulation causes bacteremia, which has a high mortality rate. Therefore, understanding the immunologic barriers that prevent dissemination is critical to developing novel treatments. In this study, we demonstrate that an S. aureus breach across skin leads to some migration of the pathogen to the draining lymph node, but no further...

Botryomycosis is a rare, chronic granulomatous infection caused by a response to bacteria, most commonly Staphylococcus aureus. Cutaneous manifestations, such as subcutaneous nodules, nonhealing ulcers, or sinus tracks, typically occur following inoculation of bacteria after trauma. Drainage from the skin lesions may contain yellow grains resembling those seen in actinomycosis and nocardiosis. A 20-year-old Hispanic male presented over the course of several years with a chronic nonhealing left posterior scalp wound...

BACKGROUND: Lung transplantation has revolutionized the treatment of end-stage pulmonary disease due to cystic fibrosis. However, infection of the transplanted lungs can lead to serious complications, including graft failure and death. Although many of these patients have concurrent sinusitis, it is unclear whether bacteria from the sinuses can infect the allograft. METHODS: This is a single-institution retrospective study of all patients who underwent lung transplantation for cystic fibrosis from 2005 to 2015 at Duke University Hospital...
