Article Synopsis
  • Nasal hemangiomas typically appear in the front part of the nose but can occasionally develop in unusual areas, like the posterior inferior meatus, as evidenced by a case study.
  • A 79-year-old man experienced nosebleeds and nasal obstruction due to a cavernous hemangioma discovered during an endoscopic evaluation.
  • The hemangioma was surgically removed without complications, and no recurrence was noted after two years, suggesting that forceful nose blowing may trigger this rare condition.

Allergen immunotherapy is regarded as the only disease-modifying treatment option for various allergic conditions, including allergic rhinitis and asthma. Among the routes of administration of allergens, sublingual immunotherapy (SLIT) has gained clinical interest recently, and the prescription of SLIT is increasing among patients with allergies. After 30 years of SLIT use, numerous pieces of evidence supporting its efficacy, safety, and mechanism allows SLIT to be considered as an alternative option to subcutaneous immunotherapy.

Actinomycosis is common in the head and neck region but rarely occurs in the nasal septum. A 75-year-old male patient with an edentulous maxilla, hypertension, and diabetes developed actinomycosis confined to the nasal septum and showed mucosal necrosis and septal bony sequestration. The patient underwent surgery and medication therapy; this case was reported using endoscopic photographs and radiographs and a literature review was conducted to provide further context and understanding of the condition of the patient.

Allergen immunotherapy (AIT) is a causative treatment for various allergic diseases such as allergic rhinitis, allergic asthma, and bee venom allergy that induces tolerance to offending allergens. The need for uniform practice guidelines in AIT is continuously growing because of the increasing discovery of potential candidates for AIT and evolving interest in new therapeutic approaches. This guideline is an updated version of the Korean Academy of Asthma Allergy and Clinical Immunology recommendations for AIT published in 2010.

In the era of novel coronavirus epidemics, vaccines against coronavirus disease 2019 (COVID-19) have been recognized as the most effective public health interventions to control the pandemic. An adverse event following immunization (AEFI) is defined as any untoward occurrence following immunization, and the majority of AEFIs are caused by protective immune responses stimulated by vaccines. Most of the reported AEFIs are not serious, and many are not immunologically mediated or even reproducible on re-exposure.

Background: Because severe cutaneous adverse reactions (SCARs), such as Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS) rarely occur, clinical data based on large-scale studies are still lacking.

Objective: To provide information on culprit drugs and clinical characteristics, including morbidity and mortality of SCARs based on a nationwide registry.

Methods: SCAR cases that occurred from 2010 to 2015 were recruited to the Korean SCAR registry from 34 tertiary referral hospitals.

Background: The human leukocyte antigen (HLA)-B*13:01 was reported as an important risk factor for dapsone hypersensitivity syndrome (DHS) in Chinese and Thai populations.

Research Design And Methods: From the Korean nationwide registry, seven subjects with previous DHS were included. Their HLA allele/phenotype frequencies were compared with 8 dapsone-tolerant subjects recruited from a single institution, and general population (n = 485) in Korea.

Rationale: Stylohyoid complex syndrome is characterized by various cervicopharyngeal symptoms related to the ossification and abnormality of the styloid process, stylohyoid ligament, and the lesser horn of the hyoid bone. Eagle syndrome is the most well-known of the spectra of these diseases. Although surgical treatment is considered effective, conservative treatment may be beneficial if symptoms arise because of inflammation of the soft tissues attached to the styloid process or hyoid bone.

Lipomas are the most common soft tissue lesions occurring in the salivary glands but have a very low incidence. Lipomas commonly occur in the parotid gland, and lipomas in the submandibular gland (SMG) are rare. Until recently, ordinary lipomas of the parotid gland and some variants of lipomas of the SMG have been reported.

Background: Hereditary angioedema (HAE) is a genetically heterogeneous autosomal dominant disorder characterized by recurrent episodes of nonpruritic, nonpitting edema increasing after puberty. It can be fatal due to laryngeal or gastrointestinal (GI) involvement with varied and changing frequency of mortality according to studies published from the Western countries. Epidemiological and clinical data of HAE in Asian countries are sparse.

Introduction: Antrochoanal polyps (ACPs) have several unique features that distinguish them from other nasal polyps. Despite many investigations, the pathogenesis of ACP has not yet been elucidated. Sinonasal osteoma is the most common type of tumor of the sinonasal tract and can be caused by trauma, infection and developmental anomaly.

Spontaneous temporomandibular joint (TMJ) herniation is the entity of protrusion of the retrodiscal contents of the TMJ into the external auditory canal (EAC) through a persistent Huschke's foramen. There have been a number of reports of spontaneous TMJ herniation, but there are no reports of bilateral symptomatic TMJ herniation. We report a case of a 70-year-old man who complained of a crunching sound in both ears during mastication.

We present a promising electrolyte candidate, Mg(TFSI)2 dissolved in glyme/diglyme, for future design of advanced magnesium (Mg) batteries. This electrolyte shows high anodic stability on an aluminum current collector and allows Mg stripping at the Mg electrode and Mg deposition on the stainless steel or the copper electrode. It is clearly shown that nondendritic and agglomerated Mg secondary particles composed of ca.

This study investigated the tendency of overpassivization of unaccusative verbs by Korean learners of English as a foreign language (FL). Sixty Korean native college students participated in the study, along with 17 English-speaking counterparts serving as a comparison group. Consistent with the findings of previous research, this study found Korean students' tendency to incorrectly accept passive-voice with inanimate subjects.
