Abstract Psoriasis is a chronic inflammatory skin disease with numerous involved factors. miR‐146a and miR‐146b (miR‐146a/b) are anti‐inflammatory miRNAs that are increased in psoriatic skin. SERPINB2 has been shown to be upregulated in the inflammation and infections. Here we aimed to study the relationship between miR‐146a/b and SERPINB2 and to delineate the role of SERPINB2 in association of plaque psoriasis. We report increased SERPINB2 expression in the skin of psoriasis patients, which was...

Objective: This article describes the case report of a prostate adenocarcinoma in the mandible. Background: Prostate adenocarcinoma is a malignant tumor common in men from the fourth decade of life. The occurrence of oral metastatic lesions is rare. Case Report: A 78-year-old male patient was referred to the oral and maxillofacial surgery service of the Pontifical Catholic University of Rio Grande do Sul for complaints of painless volume increase in the mandible. The diagnosis through...

Hyaluronic acid is among the most commonly used cosmetic fillers. Although considered biocompatible and safe, it may rarely cause a wide range of complications. The authors report a case of migration of hyaluronic acid concomitant with granulomatous inflammatory response that mimicked a buccal tumor. A 52-year-old female presented with a solid painless mass of the right buccal area. The patient denied any history of trauma and cosmetic procedures of the affected area. Skin and mucosal membrane were...

Agnathia-otocephaly complex (AOC) is a rare malformation complex of the first pharyngeal arch that is characterized by agnathia/dysgnathia, microstomia, aglossia/hypoglossia and variable displacement of the ears. Only 11 post-infancy patients with severe AOC have been described in the literature, and the incidence of this malformation complex is estimated to be 1 per 70,000 births. In this brief clinical study, the authors describe the case of an 18-year-old female diagnosed with AOC who underwent...

Langerhans cell histiocytosis (LCH) is a rare disorder defined by the abnormal proliferation of Langerhans cells. While LCH can present at any age, it is classically described as a pediatric condition, and is therefore overlooked in the adult patient. Additionally, depending on tumor burden and location, LCH can manifest with a host of oral and systemic symptoms which further confuses the clinical presentation and ultimate diagnosis. The authors present a unique report of an elderly Hispanic male...

A 76-year-old man presented with 1 day history of eyelid swelling and decreased vision on the left side. History reveals nose blowing the night prior to the occurrence of the symptoms. Initial examination of the left eye showed decreased visual acuity, increased intraocular pressure, and limited ocular motility with presence of air bubbles under the bulbar conjunctiva. Imaging studies showed medial orbital wall fracture with severe emphysema. The patient was observed for a week and no active surgical...

The aim of this study was to investigate whether it is possible to pull the platysma effectively in the medial or lateral direction (medial platysmaplasty and lateral platysmaplasty) and to explore the anatomical basis of those findings. Six hemifaces from 3 fresh cadavers were dissected. After skin removal, the platysma was pulled upward and in the medial or lateral direction with the ulnar side of the palm. Its mobility was checked. In 2 volunteers, using wooden bar, the skin overlying platysma...

Osteoma is a benign osteogenic lesion that arises most frequently in the craniomaxillofacial region. Rarely, it can appear on the outer side of nasal bone and cause aesthetic problems. The authors present an unusual case of outer side nasal bone osteoma with a brief review of its main clinical presentations, diagnostic studies, and treatment options.

The parapharyngeal space (PPS) is an anatomically and functionally complex region of the craniofacial district. Tumors that originate from this region are rare, and surgery is currently the best practice in the vast majority of cases with different surgical approaches being reported in the literature. Recently, mini-invasive robotic/endoscopic techniques have begun to emerge as effective alternatives in selected cases. In this work, we retrospectively analyzed 17 patients affected by PPS tumors,...

To investigate the difference of adipogenesis in orbital preadipocytes between pediatric and adult Graves ophthalmopathy (GO) under lipopolysaccharide (LPS)-induced inflammation in vitro. Orbital preadipocytes from pediatric and adult GO patients during eyelid or orbital surgery were cultured. The orbital preadipocytes in pediatric and adult GO were divided into group A and group B. In group A, pediatric and adult orbital preadipocytes were differentiated in adipogenesis media without LPS intervention,...

Although a large amount of studies have manifested resting state electroencephalogram oscillatory abnormalities in schizophrenia and their first-degree relatives and in schizotype, the results are far from consistent and no research found any relationship between electroencephalograph (EEG) abnormalities and schizotypal personality in first-degree relatives. The present study is to verify the modifications of EEG power spectra in eyes-open resting state of schizophrenia and first-degree relatives,...

To explore the involvement of hypoxia-inducible factor-1 alpha (HIF-1α) in the upregulation of P-glycoprotein (P-gp) in refractory epilepsy. Brain tissue specimens were collected and analyzed for expression of HIF-1α and P-gp using an immunohistochemical (IHC) staining method in both refractory epilepsy group and control group. Correlation between HIF-1α and P-gp expression level in refractory epilepsy group was analyzed. Then, a hypoxia cell model was established by simulating the nerve cell hypoxic...

Objectives: Wideband acoustic immittance (WAI) noninvasively assesses middle ear function by measuring the sound conduction over a range of audible frequencies. Although several studies have shown the potential of WAI for detecting the presence of middle ear effusions (MEEs), determining the effects of MEE type and amount on WAI in vivo has been challenging due to the anatomical location of middle ear cavity. The purpose of this study is to correlate WAI measurements with physical characteristics...
