Atypical odontalgia and trigeminal neuralgia: psychological, behavioral and psychopharmacological approach in a dental clinic – an overview of pathologies related to the challenging differential diagnosis in orofacial pain
No full textOrofacial pain represents a challenge for dentists, especially if it does not have an odontogenic origin. Orofacial neuropathic pain may be chronic, is arduous to localize and may develop without obvious pathology. Comorbid psychiatric disorders, such as anxiety and depression, coexist and negatively affect this condition. This article presents one case of atypical odontalgia and one of trigeminal neuralgia treated with psychological and psychopharmacological tailored and adapted therapies, after conventional medications had failed. Additionally, an overview of the pathologies related to the challenging differential diagnosis in orofacial pain is given. A 68-year-old man complained of chronic throbbing and burning pain in a maxillary tooth, which worsened upon digital pressure. Symptoms did not abate after amitriptyline therapy; psychological intervention along with antianxiety drug were supplemented and antidepressant agent dosage were incremented. The patient reported improvement and satisfaction with the multidisciplinary approach to his pathology. A 72-year-old man complained of chronic stabbing, intermittent, sharp, shooting and electric shock-like pain in an upper tooth, radiating and following the distribution of the trigeminal nerve. Pain did not recur after psychological intervention and a prescription of antidepressant and antianxiety agents, while carbamazepine therapy had not been sufficient to control pain. Due to concerns with comorbid psychiatric disorders, we adopted a patient-centered, tailored and balanced therapy, favorably changing clinical outcomes. Comorbid psychiatric disorders have a negative impact on orofacial pain, and dentists should consider adopting tailored therapies, such as psychological counselling and behavioral and psychopharmacologic strategies, besides conventional treatments. They also must be familiar with the signs and symptoms of orofacial pain, obtaining a comprehensive view of the pathologies concerning the differential diagnosis. A prompt diagnosis may prevent pain chronicity, avoiding an increase in complexity and a shift to orofacial neuropathic pain and legal claims
Archaeometallurgical researches in the Othris mountains (Greece)
No full textDuring a survey in an area of the Othris Mountains between Lamia and Dhomokos (Greek mainland) some slag heaps and ancient mining sites were examined and relevant samples collected. In the mining areas the main ores are copper sulphides and carbonates. No underground mine exploration was undertaken, so it was not possible to ascertain if the traces of ancient mining have survived the recent ore mining activities. Slags were found with Hellenistic sherds on the surface of some of the mining areas and in some of the settlement sites.
We have analysed different typologies of silicate slags: heavy and glassy slags. Some samples of furnace fragments have also
been analysed as well as few metallic slags (heavy slags), interpreted as remains of the reduction of copper ores. Principal phases observed are orthopyroxene, minor amounts of olivine and metallic phases. Textural evidence and mineral composition account for a reconstruction of the Cu-reduction process, which can be considered as efficient and accurate. The furnace fragments testify of the strong interaction between the charge and the furnace itself. The firing structure is thus participating in the reduction process together with ore and fuel

A case series analysing patients with dental anxiety : A patient-centered model based on psychological profiling
No full textAnxiety and distress can jeopardize dental care experience of patients and may affect the clinical result. Although a wide range of sedation and analgesia techniques are currently available to relieve distress and pain during dental procedures, operative models to choose the most effective sedation-analgesic strategies are still insufficient. This case series proposes a patient-centered model to optimize patients' cooperation during dental care delivery. We describe how to achieve correct anaesthesia by using the least sedative procedure, accounting for the dental procedure needed and patient's psychological profile. Five patients were considered as paradigmatic to show the balance between patients' subjective experiences and the clinical procedures: a patient with low stress, good compliance (case 1); a patient with moderate stress and reduction in compliance (case 2); anxious patient (case 3); a patient with acute anxiety and emotional distress (case 4); anguished patient (case 5). A multimodal treatment of emotional and behavioural condition and a patient-centered model approach contributed to achieve the best patient satisfaction in the five cases detailed here

Iron Age silicatic slags from Val Malenco (Italy): the role of textural and compositional studies in archaeometry.
No full textA petrographic study of copper smelting slags from several localities of Val Malenco (Italy) provides a key for unravelling the technologies used in reduction of copper ores during the Iron Age.
Thick “tap type” slags with “rope surface” structures and thin, flat slags, were analysed. All slags are made of olivine (up to 60%), oxides, sulfides, minor interstitial Fe-rich pyroxenes (esseneite and augite) and glass. Olivine is zoned, with Mg-rich cores, Fe-rich inner rims and thin Ca-rich outer rims. Observed mesh textures and the compositions of olivine cores and relic minerals, such as Cr-rich spinel, suggest that the mineralised levels of the Malenco ophiolitic complex were the source of the exploited ore. Ca-rich olivine rims and Ca-rich interstitial phases suggest a Ca-rich material was supposedly added during smelting to lower the melting point of the ore. The material used for this task could have been marbles or calcschists of ophicarbonates outcropping nearby Lanzada. Based on petrological considerations, the smelting conditions were constrained to a furnace in which, for
temperatures around 1080-1200 °C, oxygen fugacity was 10-13-10-8 atm
