Proboscis lateralis with associated orbital cyst: detailed MR and CT imaging and correlative embryopathy.
Proboscis lateralis is a rare craniofacial malformation. We present a case in a 1-week-old male infant, describe the clinical and imaging findings, and discuss the pertinent embryology. MR and CT proved to be complementary: CT provided anatomic detail in bone, defined the nasal cavity, and aided in determining the relationship of the proboscis and orbit; MR clarified the relationship of the pro...
متن کاملEvaluation of Children with Chronic Rhinosinusitis after Adenotonsillectomy
Introduction: Chronic rhinosinusitis (CRS), defined as an inflammatory process involving the paranasal sinuses that continues for at least three months, is a major cause of morbidity in the pediatric population and a difficult entity to treat with a poorly defined pathophysiology. The cornerstone of treatment for children with CRS remains aggressive antibiotic therapy, but many patients fail t...
متن کاملHydrophobic-hydrophilic dichotomy of the butterfly proboscis.
Mouthparts of fluid-feeding insects have unique material properties with no human-engineered analogue: the feeding devices acquire sticky and viscous liquids while remaining clean. We discovered that the external surface of the butterfly proboscis has a sharp boundary separating a hydrophilic drinking region and a hydrophobic non-drinking region. The structural arrangement of the proboscis prov...
متن کاملHawkmoths evaluate scenting flowers with the tip of their proboscis
Pollination by insects is essential to many ecosystems. Previously, we have shown that floral scent is important to mediate pollen transfer between plants (Kessler et al., 2015). Yet, the mechanisms by which pollinators evaluate volatiles of single flowers remained unclear. Here, Nicotiana attenuata plants, in which floral volatiles have been genetically silenced and its hawkmoth pollinator, Ma...
متن کاملThe Prevalence of Allergic Rhinitis in Patients with Chronic Rhinosinusitis
Introduction: Chronic rhinosinusitis (CRS) is a multifactorial disease. Allergies are considered a predisposing factor to CRS; however, this remains controversial. The objective of this research was to investigate the prevalence of co-morbidities and allergic reaction, and to specify the most common allergens in patients with confirmed CRS. Materials and Methods: One hundred patients with sig...
