Granulomatosis with polyangiitis (GPA) is a systemic disease characterized by necrotizing, granulomatous vasculitis of the upper and lower respiratory tracts and glomerulonephritis, and is classified as a classical or limited form. The classical form of GPA demonstrates the involvement of the upper respiratory tract, sinuses, lungs and kidneys, whereas the limited form is characterized by the lack of the renal involvement with female predominance. On the other hand, mixed connective tissue disease (MCTD) shows the clinical and laboratorial features of systemic lupus erythematosus, systemic sclerosis and polymyositis, along with high titers of anti-ribonucleoprotein antibodies and is characterized by good response to corticosteroid therapy and favorable prognosis...

A 71-year-old female patient with no major history of infection had presented with recurrent chronic purulent sinusitis over the past 3 years. These recurrent infections started in 2000 with otolaryngologists' support before diagnosis of IgG4 deficiency be asked. The patient was treated with increasingly extensive courses of antibiotics and underwent several maxillary and sphenoidal sinus washouts. She continued to present with purulent nasal discharge containing Staphylococcus epidermidis. The blood and immune work-ups were normal...

BACKGROUND: Surgical management of the frontal sinus can be challenging. Extensive frontal sinus pneumatization may form a far lateral or supraorbital recess that can be difficult to reach by conventional endoscopic surgical techniques, requiring extended approaches such as the Draf III (or endoscopic modified Lothrop) procedure. Rigid endoscopes may not allow visualization of these lateral limits to ensure full evacuation of the disease process. METHODS: Here we describe the utility of intraoperative flexible endoscopy in two patients with far lateral frontal sinus disease...

The pore-forming α-subunit of the cardiac voltage-gated sodium channel, NaV 1.5, is responsible for the initial upstroke of the cardiac action potential. NaV 1.5 cell surface expression and function are modulated by its interaction with regulatory proteins and by posttranslational modifications, such as phosphorylation, arginine methylation or ubiquitination (1) . Genetic mutations in the SCN5A gene, which encodes NaV 1.5, have been associated with a variety of inherited cardiac arrhythmias, including long QT syndrome type 3, Brugada syndrome, atrial fibrillation, and congenital sick sinus syndrome...

A 58-year-old man with a long R-P' narrow QRS tachycardia underwent an electrophysiological study. The tachycardia was diagnosed as permanent form of junctional reciprocating tachycardia (PJRT), and the earliest atrial activation site during tachycardia was coronary sinus (CS) ostium. Radiofrequency ablation at the site was initially not successful because the tip impedance and temperature were unstable. After changing of the ablation catheter to that with contact force sensor, the accessory pathway was immediately ablated and the PJRT was no longer induced...

Kaitlin Moore, Ann Ross
Assessment of development is an important component of age estimation in juveniles. One area that has not been fully investigated as a possible aging method is the development of the frontal sinus. The frontal sinuses form when the ectocranial table of the frontal bone separates from the endocranial table forming an air pocket in the bone. The endocranial table ceases growth with the brain, while the ectocranial table is displaced anteriorly as the facial bones continue growth. In order to examine growth and the utility of the frontal sinuses for age estimation, 392 radiographs were examined (♀=159 and ♂=233) from the Juvenile Radiograph Database at North Carolina State University and the Patricia Database from Mercyhurst University...

Scimitar syndrome is the constellation of malformations including an abnormal venous drainage of the right lung into the inferior vena cava, associated with the right lung and systemic supply to the right lung. The anomalous vein looks like the curved, Turkish sword (scimitar), hence the name.The adult form of scimitar syndrome is rare, and it is usually an incidental diagnosis based on the characteristic finding on radiological imaging since the patients are usually asymptomatic or with minimal symptoms.Our patient presented with a rare presentation of scimitar syndrome, which is tachyarrhythmia (sinus tachycardia, with episodes of supraventricular tachycardia)...

Recurrence of allergic fungal rhinosinusitis (AFRS) is well recognized. However, there is scarcity in the literature describing involvement of the non-diseased sinuses. We aimed to evaluate the recurrence forms of unilateral AFRS as well as to study the possible predictor factors of developing the disease in the contralateral side. Patients with exclusive unilateral AFRS from (2010 to 2015) were enrolled in multi-institutional case-control study. All patients were evaluated after endoscopic sinus surgery for recurrence...

REVIEW
Kelly Schultz, Tara L Braun, Tuan A Truong
The frontal bone serves a protective role, representing the transition between the facial skeleton and the cranium. Within its enclosure, the frontal sinus lies adjacent to many important intracranial structures, and injury to this region has severe complications if not properly managed. Historically, the goals of frontal sinus fracture management have been to best prevent intracranial complications with invasive procedures, but a recent shift favoring conservative management now aims to preserve the form and function of the frontal sinus and its outflow tract...

PURPOSE: Many histologic and histomorphometric studies as well as systematic reviews have shown the clinical success of the use of anorganic bovine bone (ABB, Bio-Oss) in maxillary sinus floor augmentation (MSFA). The molecular processes involved in bone healing are, however, still unknown. The aims of this study were to explore gene expression associated with bone remodeling and inflammation in MSFA sites. MATERIALS AND METHODS: The mRNA expression levels of runt related transcription factor 2 (RUNX2), receptor activator of NF-kB ligand (RANKL), osteoprotegerin (OPG), matrix metallopeptidase 9 (MMP-9), tartrate-resistance acid phosphatase (TRAP), and interleukin-1beta (IL-1β), as well as the ratio of RANKL/OPG were compared between alveolar bone of a group after MSFA with ABB and a maxillary posterior edentulous bone group...

BACKGROUND: It is still unclear whether enamel matrix proteins (EMD) as adjunct to bone grafting enhance bone healing. This study compared histomorphometrically maxillary sinus floor augmentation (MSFA) with β-TCP/HA in combination with or without EMD in humans. METHODS: In ten systemically healthy patients needing bilateral MSFA, one side was randomly treated using β-TCP/HA mixed with EMD (BC + EMD) and the other side using only β-TCP/HA (BC). After 6 months, biopsies were harvested from grafted areas during implant installation, being histologically and histomorphometrically analyzed...

REVIEW
Darko Orešković, Milan Radoš, Marijan Klarica
The classic hypothesis presents the cerebrospinal fluid (CSF) as the "third circulation," which flows from the brain ventricles through the entire CSF system to the cortical subarachnoid space to eventually be passively absorbed into the superior sagittal sinus through arachnoid granulations. The choroid plexus (CP) represents a key organ in the classic CSF physiology and a powerful biological pump, which exclusively secretes CSF. Thereby, the CP is considered to be responsible for CSF pressure regulation and hydrocephalus development...

Osteomas are benign osteogenic lesions that result from the proliferation of mature bone. Three variants are known: central, peripheral, and extraskeletal. The peripheral variant is the most common and it most frequently affects the paranasal sinuses, rarely occurring in the jaws. This article describes the case of a 33-year-old white male patient who was referred complaining of facial asymmetry. Clinical examination revealed an increase in volume at the base of the right side of the mandible, hard bony consistency and well delimited, painless to the touch, without signs of infection or intraoral alterations...

INTRODUCTION: The clinical features, management, and the associations of dosage in poisoning with the cardiotoxic plant Cerbera odollam (suicide tree), responsible for more than half of plant poisoning deaths in the South Indian State of Kerala alone, have not been evaluated. There are only few studies on its clinical features and none on the usage of cardiac pacing in its management, given its rarity in the Western world. We depend on data for similar toxins to form our management protocols...

A 62 year-old male with long-standing smoking history presented with hemoptysis. Plain chest x-ray showed abnormal findings proximate to the right pulmonary hilum. Bronchoscopy revealed a fragile exophytic tumor of the right wall of the lower third of the trachea, infiltrating the right main bronchus (75% stenosis) and the right upper lobar bronchus (near total occlusion). Contrast-enhanced chest CT demonstrated a 7.2x4.9 cm tumor contiguous to the above-mentioned structures, mediastinal lymph node pathology, and a vessel coursing inferiorly to the left of the aortic arch and anterior to the left hilum...
