Abstract

Primary open-angle glaucoma (POAG) represents the most common form of a heterogeneous group of glaucomatous optic neuropathies which are a worldwide cause of irreversible blindness. Immune dysregulation and the genetic background are considered important risk factors. The influence on susceptibility to POAG of single nucleotide polymorphisms (SNPs) of tumor necrosis factor-α (TNF-α) was intensively studied, mostly on Asian population. We investigated the possible association of two TNF-α SNPs (-308G/A and -857C/T) with susceptibility to POAG and its clinical characteristics. A case-control association study of aforementioned TNF-α SNPs was performed on 197 POAG patients (divided into two subgroups: high-tension and normal-tension glaucoma - HTG/ NTG) versus 208 ethnically matched controls. This is the first study performed on Romanian population. No significant differences were found in terms of allelic frequencies, genotype distribution of the studied SNPs, or their haplotypes between POAG and healthy control groups. In the subgroup analysis, TT genotype of TNF-α -857T-allele was found to be associated with higher values of central corneal thickness (CCT) in NTG subgroup (p-value 0.032). In order to confirm the association between -857C/T SNP of TNF-α and CCT in NTG subgroup of POAG patients, additional studies on different populations should be performed.

Abstract

BACKGROUND. Odontogenic rhinosinusal suppurations have a high potential for major ocular-orbital and cerebral complications because of the presence of anaerobic bacteria flora, with continuity, contiguity and haematogenous propagation mechanisms. This pathology is often diagnosed in other departments than ENT such as ophthalmology, neurosurgery or OMF surgery.

MATERIAL AND METHODS. We present three clinical cases of odontogenic rhinosinusal suppurations with major complications: a 36-year-old patient with odontogenic pansinusitis complicated with orbital phlegmon and cerebral frontal lobe abscess; a 19-year-old patient with complicated maxillary-ethmoidal-frontal sinusitis complicated with frontal subdural empyema and frontal bone osteomyelitis (with a history of craniofacial trauma one year before); a 66-year-old patient with odontogenic maxillary-ethmoidal sinusitis complicated with orbital apex syndrome.

RESULTS. The treatment was surgical, by external approach, with endoscopic nasal control, in interdisciplinary teams. We have associated massive antibiotic therapy. Surgical drainage for complicated rhinosinusitis should be done in emergency, within the first 24 hours after admission, according to guidelines. The bacteriological examination for aerobic and anaerobic flora can guide the diagnosis - two cases associated maxillo-ethmoidal aspergilloma lesions. The evolution of the cases was favourable.

CONCLUSION. Interdisciplinary teams have successfully solved these complicated odontogenic rhinosinusal suppurations. Two of the cases were admitted and cured within 2 weeks, in the context of very hot weather, which exacerbated dormant dental infections.
