α-Resolvable λ-fold G-designs

A λ-fold G-design is said to be α-resolvable if its blocks can be partitioned into classes such that every class contains each vertex exactly α times. In this paper we study the existence problem of an α-resolvable λ-fold G-design oforder v in the case when G is any connected subgraph of K_4 and prove that the necessary conditions for its existence are also sufficient

Large Follicular Cyst Associated with Upper Third Molar in the Maxillary Sinus with Pterygomaxillary Space Extension: Reflection on a Case Report

BACKGROUND: Follicular cysts are osteolytic lesions characterized by greater growth, differentiation, and degeneration potentials, compared to inflammatory root cysts. Those connected to upper third molars can disrupt the neighboring teeth and extend to maxillary sinus and adjacent anatomical structures. CASE PRESENTATION: In this study, we present a case of a large dimension follicular cyst associated with the upper third molar, extended to maxillary antrum and pterygomaxillary space, uncommon for dimensions, involving meso- and sovra-structure describing the clinical diagnostic procedures, and the surgical strategies adopted. The cone-beam computed tomography allowed a very accurate analysis of the lesion. Surgical excision was performed through Caldwell-Luc technique, approaching to the pterygomaxillary space. A 1-year follow-up shows good clinical, anatomical, and functional conditions. Histological examination confirmed the diagnosis of follicular cyst. CONCLUSION: Giant follicular cysts require an accurate pre-operative study due to the delicate structures that may be involved

Antimicrobial potential of Sicilian honeys against commensal Escherichia coli and pathogenic Salmonella serovar Infantis

Introduction. The purpose of this study was to investigate the antibacterial effect of 71 locally produced honeys from different botanical sources collected from apiarist?s open markets in Sicily. Methods. Antimicrobial activity was determined against Escherichia coli (ATCC 25922) and Salmonella serovar Infantis (ATCC 1523) by an agar-diffusion assay from the estimation of the diameter of the inhibition zone produced by the honeys. Statisti- cally significant differences (P inf. .000) regarding inhibition were observed for the honeys tested. Results. The chestnut and polyfloral honey samples exhibited the largest and highest inhibition (diameter of the inhibition zone > 25 mm) against both E. coli and S. Infantis. The honey of oregano origin showed intermediate or low activity against E. coli and S. Infantis, respectively. Prickly pear and erica honeys showed no antimicrobial activity against the two reference strains. Discussion. The results may partially suggest the usefulness of the Sicilian honeys on treating multi-resistant enterobacteria. In light of the enormous potential for application of honey in the clinical practice, it is important that research continues not only into those honeys well recognized as antimicrobial, but also into other locally produced and yet untested honeys

Radiation Macular Edema after Ru-106 Plaque Brachytherapy for Choroidal Melanoma Resolved by an Intravitreal Dexamethasone 0.7-mg Implant

Purpose: To report the effective treatment of radiation macular edema following ruthenium-106 plaque brachytherapy for a choroidal melanoma with a dexamethasone 0.7-mg (Ozurdex®) intravitreal implant. Methods: An interventional case report with optical coherence tomography (OCT) scans. Results: A 65-year-old Caucasian woman was suffering from radiation macular edema following ruthenium-106 plaque brachytherapy for a choroidal melanoma on her left eye. She had undergone one intravitreal injection of 0.5 mg bevacizumab (Avastin®, Genentech/Roche) in the following months without functional or anatomical improvement. Seven months after the development of radiation macular edema, she received a single intravitreal injection of dexamethasone 0.7 mg (Ozurdex). Four weeks following the injection, her best-corrected visual acuity improved from 0.3 to 0.5. Radiation macular edema resolved with a reduction of central retinal thickness from 498 µm before Ozurdex injection to 224 µm after Ozurdex injection, as measured by OCT scan. Conclusion: Dexamethasone 0.7 mg (Ozurdex) has proven to be an effective treatment option in retinal vein occlusion and noninfectious uveitis. It can also be considered as off-label treatment in radiation macular edema following ruthenium-106 plaque brachytherapy for a choroidal melanoma
