Migrazioni ed insediamenti informali: riflessioni sul caso siciliano
2022
Over the last fifty years, many European regions in the Mediterranean area, historically considered as areas of origin of international migration flows, have been transformed into places of reception. At the basis of this mobility is, among many factors, the demand, by a variable and globalised economy, for 'easy' labour, mostly made up of new immigrants, instrumental to that particular local economic system. Analysing the spatial dimension of the phenomenon, it highlights how the inadequacy and insufficiency of reception places and the increase in eviction phenomena contribute to the significant increase in the phenomenon of informal settlements in peripheral urban contexts, making it diff…
Il fenomeno migratorio e gli insediamenti informali, un focus sul territorio siciliano
2023
Il fenomeno dei flussi migratori, che da oltre vent'anni si registra in Europa in modo esponenzialmente crescente, ha rappresentato - e continua a rappresentare - un elemento di grande cambiamento nel quadro sociale europeo. Rispetto al suddetto scenario, i fenomeni di globalizzazione, le recenti trasformazioni socio-economiche e quelle del mercato del lavoro, sono alla base della convergenza di un articolato sistema di fattori interdipendenti che determinano il continuo mutamento dei rapporti tra paesi di origine e paesi di destinazione dei flussi migratori. Analizzando la dimensione spaziale, che mostra l'inadeguatezza e l'insufficienza dei luoghi di accoglienza e l'aumento dei fenomeni d…
A new aid modality for Africa
2013
Preprint of an article published in the Journal of Economic Policy Reform with the title:“Stimulating economic growth in the least developed countries: Direct cash transfers for the retired via mobile phones,” The result of current aid policies is that only a small percentage of foreign aid reaches the poorest of the poor in the least developed countries. Current trends of urbanisation and self-reliance place elderly people in an increasingly difficult situation. This paper aims to stimulate debate by introducing an alternative mechanism for foreign aid. With the help of an economic model, we demonstrate how direct cash transfers to elderly people can spur economic growth. Targeting all eld…
Indirect chronology method employing rare earth elements to identify Sagunto Castle mortar construction periods
2017
A novel indirect chronology method has been developed to identify Sagunto Castle construction periods. The method is based on the use of inductively coupled plasma mass spectrometry (ICP-MS) to determine rare earth elements (REE) and other trace elements in mortars. Additionally, a no destructive geochemical analysis based on X-ray fluorescence (XRF) was employed for major elements determination. Collected chemical data were processed through Principal Component Analysis (PCA) to highlight any differences among the mortars belonging to different buildings and construction periods. The results show that PCA analysis permits to discriminate construction periods according to mortar sample REE …
Ultrasound-guided percutaneous treatment of a calcific acromioclavicular joint
2020
Abstract Rationale: Calcific tendinopathy is one of the most frequent causes of nontraumatic shoulder pain. However, intra-articular calcifications appear to be an infrequent condition. We herein report a rare case study of an intra-articular calcification of the acromioclavicular joint. Patient concerns: A 46-year-old man presented with an acute pain in the anterior superior region of the left shoulder which also radiated to the left cervical region. The man during the physical evaluation also presented severe functional limitation of the shoulder movements in all planes of motion. Diagnoses: The diagnosis was carried out through a radiographic and an echotomographic examination, highlight…
Small cell osteosarcoma of mandible: a rare case report and review of literature.
2010
Osteosarcoma is the most common primary malignant tumor of bone but only 5% of these tumours occur in the jaws. Of all the varieties of osteosarcoma, the juxtacortical type is rare and comprises only less than 4% of all osteosarcomas. Juxtacortical osteosarcoma is further subdivided into parosteal (low grade) and periosteal (high grade). Osteosarcomas can be categorized histologically mainly into chondroblastic, osteoblastic, fibroblastic and numerous others. One of the rare histological variant is small cell osteosarcoma which consists of sheets of round cells that produce an osteoid matrix. The aim of this article is to present a rare case of periosteal osteosarcoma of mandible which on h…
Acupuncture in the treatment of temporomandibular disorders, facial pain, and postural neuromuscular disorders. Presentation of a clinical case
2021
Abstract Background and objectives Temporomandibular disorders have a multifactorial etiology and involve the masticatory muscles, temporomandibular joint and associated structures. Therefore, different treatments are proposed and used. The aim of this paper is the use of acupuncture to treat temporomandibular disorders and associated symptoms. This article presents a clinical case study of a 39-year-old patient who presented temporomandibular disorders and headache of muscular origin. Results After 10 acupuncture sessions, the results were highly satisfactory, with complete relief of headache pain and absence of joint disorders. These results suggest the efficacy of acupuncture in the symp…
Florid cemento-osseous dysplasia : report of 2 cases
2018
Introduction Florid cemento-osseous dysplasia is a non-neoplastic fibro-osseous lesion which often has an asymptomatic slow growth. Unfortunately, these lesions are usually diagnosed through routine radiographic examination. The aim of this study was to describe the main clinical, radiological and histological characteristics of two case reports diagnosed with florid cemento-osseous dysplasia. Case reports Two cases of florid cemento-osseous dysplasia with different clinical and radiological features were presented. Panoramic radiographs showed multiple radiopacities compatible with fibro-osseous lesions in distinct areas of the maxillary bones. The histological study revealed a sclerotic m…
Anterior dislocation in a total knee arthroplasty: A case report and literature review.
2015
Dislocations of a total knee arthroplasty (TKA) are an uncommon injury and only few cases of anterior dislocations have been reported. We report a rare case of anterior dislocation of a 10-year-old posterior stabilized total knee arthroplasty in a 74-year-old woman. The patient was successfully treated by close reduction of the dislocation followed by immobilization in full extension with a long leg cast. Because of a high risk of neurovascular complications, a high index of suspicion for vascular injury must be maintained. For this reason, a proper diagnosis is required and immediate reduction is recommended.
