BACKGROUND: The use of rituximab (RTX) is increasing, even in developing countries. It has become the first-line therapy or adjuvant to chemotherapy (CHOP; cyclophosphamide, hydroxydaunorubicin, oncovin and prednisone) for various diseases, including B cell lymphoma and autoimmune diseases. AIM: We describe the infectious diseases and immunological markers associated with RTX treatment of patients with non-Hodgkin lymphoma (NHL). METHODS: Serum immunoglobulins were determined before and after intravenous immunoglobulin (IVIg) administration...

Osteomyelitis is inflammation of the bone caused by an infectious organism, and is a difficult clinical problem. The pathophysiology, imaging, and classification of osteomyelitis are challenging, varying with the age of the patient (child versus adult), the chronicity of the infection (acute versus chronic), and the route of spread (hematogenous versus contiguous focus), as well as the immune and vascular status of the patient and affected region. The two most common classification schemes are those of Lew and Waldvogel, and Cierny and Mader...

BACKGROUND: Innovation represents a core value of the American Rhinologic Society (ARS), with multiple efforts to promote research in the advancement rhinologic care. We therefore sought to identify trends in extramural sinusitis funding and underutilized sources of support to facilitate future efforts. METHODS: A systematic review of the National Institutes of Health (NIH) Research Portfolio Online Tools (RePORTER) database (fiscal year 1993 to 2017) was completed with the search strategy: ("chronic sinusitis" OR rhinosinusitis)...

Rakul Nambiar, Sreejith G Nair
Cavernous sinus syndrome (CSS) is a condition characterized by multiple cranial nerve palsies manifesting with ophthalmoplegia, ptosis, and facial sensory loss due to involvement of adjacent cranial nerves. Tumors, trauma, and vascular, infectious, and noninfectious inflammatory disorders have all been described as causes. Lymphomas have been reported to involve the cavernous sinus, both as primary cavernous sinus lymphomas or as secondary lesions. Here, we describe the case of a 63-year-old-man with untreated chronic lymphocytic leukemia (CLL), diagnosed 4 years earlier, who presented with CSS...

Infectious diseases have a profound impact on our health and many studies suggest that host genetics play a major role in the pathogenesis of most of them. We perform 23 genome-wide association studies for common infections and infection-associated procedures, including chickenpox, shingles, cold sores, mononucleosis, mumps, hepatitis B, plantar warts, positive tuberculosis test results, strep throat, scarlet fever, pneumonia, bacterial meningitis, yeast infections, urinary tract infections, tonsillectomy, childhood ear infections, myringotomy, measles, hepatitis A, rheumatic fever, common colds, rubella and chronic sinus infection, in over 200,000 individuals of European ancestry...

REVIEW
Miriam Baron Barshak, Marlene L Durand
OBJECTIVE: To review the current understanding of the role of infection and antibiotics in chronic rhinosinusitis. REVIEW METHODS: PubMed literature search. RESULTS: Chronic rhinosinusitis (CRS) in adults is an inflammatory condition and the role of infection is unclear. Biofilms are present in both CRS and normal patients so their role in CRS is unknown. Sinus cultures in CRS demonstrate a mixture of aerobic and anaerobic bacteria but may be hard to interpret due to contaminating nasal flora...

Rhinitis and rhinosinusitis are the two major clinical entities of chronic upper airway disease. Chronic rhinosinusitis (CRS) and allergic rhinitis (AR) affect respectively up to 10 and 30% of the total population, hence being associated with an important socio-economic burden. Different phenotypes of rhinitis and CRS have been described based on symptom severity and duration, atopy status, level of control, comorbidities and presence or absence of nasal polyps in CRS. The underlying pathophysiological mechanisms are diverse, with different, and sometimes overlapping, endotypes being recognized...

The respiratory tract is lined with motile cilia that transport respiratory mucus. Primary ciliary dyskinesia (PCD) is a chronic genetic disease caused by mutations in genes responsible for ciliary structure and function. Non-functional airway cilia impair the mucociliary clearance (MCC), causing mucostasis, lung infections and destruction, chronic rhinosinusitis (CRS) and hearing impairment. It is of paramount importance to postpone chronic lung infection mainly with Gram-negative bacteria (GNB) in patients with an impaired MCC...

REVIEW

Osteosynthesis-associated infections occur in 1-5% after closed and in up to 30% after open fractures. There are three different descriptions of implant-associated infections after fracture fixation, which are crucial for the selection of the adequate treatment strategy; temporal appearance from the index surgery (early versus late), pathogenesis of the infection (exogenous, hematogenous and contiguous from an adjacent focus), duration of infection symptoms (acute versus chronic). Diagnosis of osteosynthesis-associated infection is challenging, as chronic low-grade infections often present only with unspecific and subtle clinical symptoms...

Actinomycosis, an infectious bacterial disease caused by Actinomyces species, is very rare and is characterized by contiguous spreading, subacute to chronic granulomatous inflammation and the formation of multiple abscesses and sinus tracts that may discharge sulfur granules. Actinomycosis that presents on the skin without endogenous origin is called primary cutaneous actinomycosis, and the occurrence and treatment of primary cutaneous actinomycosis is rarely reported. This report describes the treatment of primary cervicofacial actinomycosis with a literature review, and emphasizes the importance of surgical option for complete remission of the disease...

INTRODUCTION: Psoriatic patients on tumor necrosis factor alpha inhibitors (TNFi) may be at increased risk for upper respiratory tract infections, including chronic rhino-sinusitis (CRS). Rarely, CRS can progress to orbital cellulitis (OC), an emergent ophthalmic complication wherein respiratory flora from paranasal sinus disease intrude the retro-orbital space. MATERIALS AND METHODS: Single case report. RESULTS: We report the first case, to our knowledge, of an invasive sinusitis that rapidly evolved into OC in a patient receiving adalimumab treatment for plaque psoriasis and psoriatic arthritis...

Mycoplasma gallisepticum (MG) is an important pathogen that can cause chronic respiratory disease in chickens and infectious sinusitis in turkeys. MG has the ability to form biofilms. The molecular mechanisms underlying MG biofilm formation are complex and poorly understood. To better understand the mechanisms involved in biofilm formation, mini-Tn4001-SGM, a novel transposon vector containing the gentamicin gene was constructed and electroporated into MG strain Rlow. Of the 738 mutants obtained, 12 had significantly reduced capacity to form biofilms in a polystyrene microtiter-plate biofilm assay...

Phaeohyphomycosis is a chronic infectious condition caused by dematiaceous fungi which usually involve the skin and subcutaneous tissue. Subcutaneous phaeohyphomycosis is characterised by papulonodules, verrucous, hyperkeratotic or ulcerated plaques, cysts, abscesses, pyogranuloma, non-healing ulcers or sinuses. In India, commonly associated genera are Exophiala, Phialophora, Cladosporium, Curvularia, Fonsecaea and Alternaria. This condition involves the presence of brown-walled hyphal structures in the dermis and epidermis...

BACKGROUND: Diverse microbial communities colonize healthy sinus mucosa and specific species within these communities are capable of protecting the host from pathogenic infection. However, little is known of the dynamics of upper airway infection and the role of the sinus mucosal microbiome in short- and longer-term outcomes using clinical isolates from patients with chronic rhinosinusitis. METHODS: We examine microbiome and immune dynamics after murine sinus infection with Pseudomonas aeruginosa EC1, isolated previously from a chronic rhinosinusitis patient...

BACKGROUND: Acute and chronic sinusitis in children and adults can spread to the orbit. Oral flora has been seen in orbital infections, but the extent of synergy between pathogens in such infections remains unknown. METHODS: A retrospective case series of patients with complicated sinusitis that involved the orbit from acute sinusitis who were admitted to a tertiary care hospital from January 2000 to December 2014 and who had surgical cultures obtained. Patients were identified by the International Classification of Diseases, Ninth Revision code for periorbital cellulitis, subperiosteal abscess, or orbital abscess...

Hepatitis C is frequently accompanied by immune-related extrahepatic manifestations affecting the skin, kidneys, central and peripheral nervous system and exocrine glands. We present the case of a 40-year-old man with left-sided ptosis, exophthalmos and headache. MRI demonstrated left-sided orbital pseudotumor with lacrimal and retro-orbital contrast enhancement extending to the cavernous sinus and the vestibulocochlear nerve. Immunological tests of serum and cerebrospinal fluid identified hepatitis C virus (HCV) as a potential causative agent but did not indicate any additional infectious, malignant or immunological disorder...

Isolated extramedullary relapse of chronic myelogenous leukemia (CML) after allogeneic stem cell transplant is rare. There is a case report of a child who developed a granulocytic sarcoma of the maxillary and sphenoid sinuses and lumbosacral spinal cord mass 18 months after allogeneic bone marrow transplant for CML. He was presented with per orbital edema and neurological deficit of lower extremities and a mass lesion was found on spinal cord imaging. No evidence of hematologic relapse was identified at that time by bone marrow histology or cytogenetic...
