EGHB010 is a hot water extract of the rhizome mixture of Paeonia lactiflora Pallas and Glycyrrhiza uralensis Fisch. Choroidal neovascularization (CNV) and vascular leakage are the common pathophysiologies of age-related macular degeneration. In this study, we aimed to evaluate the effect of EGHB010 on retinal vascular leakage and laser-induced CNV in a rat model. Vascular endothelial growth factor- (VEGF-) induced tube formation was assayed in human retinal microvascular endothelial cells. Intravitreal VEGF-induced blood-retinal barrier breakdown was assayed in Sprague-Dawley rats...

ETHNOPHARMACOLOGY RELEVANCE: Dioscin, a spirostane glycoside, the rhizoma of Dioscorea septemloba (Diocoreacea) is used for diuresis, rheumatism, and joints pain. Given the poor solubility and stability of Dioscin, we proposed a hypothesis that Dioscin's metabolite(s) are the active substance(s) in vivo to contribute to the reducing effects on serum uric acid levels. AIM OF THE STUDY: The aim of this study is to identify the active metabolite(s) of Dioscin in vivo and to explore the mechanism of its antihyperuricemic activity...

Capnocytophaga canimorsus is a Gram-negative bacterium present in the oral cavities of cats and dogs. It is known for its capability to cause life-threatening sepsis following a dog bite, especially in immunocompromised patients. We report the case of a 67-year-old man who suffered from septic shock and multiorgan failure presumably following contamination of a pre-existing minor skin lesion by canine saliva. The purpose of this report is to raise awareness of Capnocytophaga canimorsus among physicians when faced with a patient presenting with fulminant septic shock and Gram-negative bacteremia, who has been exposed to dogs...

Inclusion of fungi as commensals in oral biofilm is an important innovation in oral biology, and this work aimed to review the literature on the available biofilm and related disease in vitro models. Actually, thousands of bacterial and around one hundred of fungal phylotypes can colonize the oral cavity. Taxonomic profiling combined with functional expression analysis has revealed that Candida albicans, Streptococcus mutans and prominent periodontopathogens are not always present or numerically important in candidiasis, caries, or periodontitis lesions...

We conducted a critical review of human papillomavirus (HPV) integration into the host genome in oral/oropharyngeal cancer, reviewed the literature for HPV-induced cancers, and obtained current data for HPV-related oral and oropharyngeal cancers. In addition, we performed studies to identify HPV integration sites and the relationship of integration to viral-host fusion transcripts and whether integration is required for HPV-associated oncogenesis. Viral integration of HPV into the host genome is not required for the viral life cycle and might not be necessary for cellular transformation, yet HPV integration is frequently reported in cervical and head and neck cancer specimens...

Kobkan Thongprasom
Topical steroids have been widely used in the treatment of symptomatic oral lesions to reduce pain and inflammation. Potent topical steroids such as clobetasol propionate, fluocinolone acetonide (FA), and fluocinonide have been widely used in the treatment of severe oral mucosal lesions. Many reports have demonstrated that these steroids were effective in treating oral lesions with only minor side-effects. This review describes the effectiveness and side-effects of using FA 0.1% in the treatment of symptomatic oral lichen planus (OLP), oral lichenoid drug reaction (OLDR), oral pemphigus, and herpes associated erythema multiforme (HAEM)...

Long-term methotrexate (MTX) treatment can cause MTX-related lymphoproliferative disorder (MTX-LPD). We experienced a case of MTX-LPD that was associated with severe osteonecrosis of the jaw mimicking medication-related osteonecrosis of the jaw. The patient was an 81-year-old woman with rheumatoid arthritis (RA) who was treated with MTX and bisphosphonate. After 7 years, she was referred to our department for the assessment of giant ulcer and exposure of the alveolar bone of the left maxilla. Histopathological and immunological analyses confirmed a diagnosis of MTX-LPD...

Antibiotic selection for maintenance of expression plasmids is discouraged in production of recombinant proteins for pharmaceutical or other human uses due to the risks of antibiotic residue contamination of the final products and release of DNA encoding antibiotic resistance into the environment. We describe the construction of expression plasmids that are instead maintained by complementation of the lgt gene encoding a (pro)lipoprotein glyceryl transferase essential for biosynthesis of bacterial lipoprotein...

This article presents the case of a patient with newly developed skin erosions and ulcerations following an exanthematous drug eruption due to sultamicillin therapy. The skin lesions were treated topically with clobetasol and prednicarbate and orally with methylprednisolone. A skin smear revealed massive growth of Escherichia coli bacteria. Blood cultures were negative. The cause for developing ecthyma gangrenosum in our patient were iatrogenic immunosuppression and transient bacteremia.

REVIEW
Tristan Klosterman, Teresa M O
Vascular malformations may affect nearly all aspects of the upper airway. Each type of malformation has a characteristic pattern of disease. These lesions may be focal or diffuse, and require directed management strategies. Physicians treating these entities should have a high level of suspicion to consider airway evaluation even in the absence of overt symptoms. However, cutaneous head and neck venous malformations or other lesions affecting the lips, oral cavity, or tongue can herald the presence of coexisting airway lesions...
