Il vuoto è pieno. Appunti e immagini sullo spazio urbano durante la pandemia
Get PDFThe paper intends to give back a photograph in motion of the relationship between city and pandemic. The reflection is divided into two sections. The first, snapshots, offers brief reflections implemented through the use of some significant images like frames, which summarize some of the most relevant aspects that the pandemic has presented with its dramatic impact. The second section consists of in-depth reflections investigating the potential of empty space, starting from two different conditions, one pre-pandemic and the other infra-pandemic. In front of the dominant portrait of a segregated city, which shuns a new ecological pact with the ecosystem to fall back on protocols of prophylaxis, hygiene and biometric systems, is highlighted the active role of the “augmented” space. This space is understood as an “augmented” and dynamic substance, shaped and fed by a computer system accompanying the transformation of spaces, services, behaviors and languages
Modelling the past. Logics, semantics and applications of neural computing in archaeology
Get PDFThe study of complex archaeological systems through the new Artificial Intelligence and Natural and Neural Computing is a research project which evaluates the historical meaning of the relationships between records of the past as an essentially human construction. It repeats a strong position of Analytical Archaeology, but updates it on the basis of the progress which neurosciences and physics have made in simulating the principles which regulate memory, orientation, classification and mapping of reality. Modelling and simulating the contexts of the past in integrated, parallel, distributed processing through machine learning methods, must make use of a precise encoding of the documents. It takes on an important role in empirical research only when the results produced become the hyper-surface of a network membrane to continue, update, refine or open the analysis itself. After some 30 years of such theoretical, analytical and experimental research, logics, semantics and applications of neural computing maintain their distinct value as a new theoretical approach for the study of dynamic and systemic cultural complexity. They provide a new analytical paradigm for computational modelling in archaeology and an advanced computational method for pattern recognition in archaeometry
Suicidio, negozio giuridico e processo di formazione del volere. Considerazioni teorico-pratiche sui riflessi dell’intenzionalità suicidaria nel diritto dei contratti
Get PDFL’alterazione degli stati psicologici, oltre ad orientare la riflessione del sapere psichiatrico e sociologico, assume precipuo valore anche in ambito giuridico, rivelandosi decisiva sia per indurre una dichiarazione non rispondente al volere, sia per sollecitare il perfezionamento di un contratto del quale non si è in grado di apprezzare appieno la reale portata né le conseguenze
COVID-19 and Pulmonary Embolism: Not a Coincidence
Get PDFIn December 2019, a novel coronavirus called SARS-CoV-2 was reported to be responsible for a cluster of acute atypical respiratory pneumonia cases in Wuhan, in Hubei province, China. The disease caused by this virus is called COVID-19 (coronavirus disease 2019). The virus is transmitted between humans and the outbreak was declared a pandemic by the World Health Organization (WHO) on 11 March 2020. Coagulopathy is a common abnormality in patients with COVID‐19 due to inflammation, hypoxia, immobilisation, endothelial damage and diffuse intravascular coagulation. However, the data on this topic are still limited. Here we report the case of a man presenting with pneumonia complicated by bilateral pulmonary embolis
Emphysematous Pancreatitis: A Rare Complication of Acute Necrotizing Pancreatitis
Get PDFEmphysematous pancreatitis is a rare and fatal complication of acute necrotizing pancreatitis. We report a radioclinical observation of a 61-year-old female patient who consulted for epigastric pain radiating to the back, associated with vomiting and elevated lipasaemia more than 3 times the normal value. The abdominal computerized tomography (CT) scan carried out on the fourth day of hospitalization, based on worsening of the clinical condition, showed pancreatic necrosis associated with the presence of air bubbles. Percutaneous puncture of a peripancreatic collection was positive for Escherichia coli. A diagnosis of emphysematous pancreatitis was established. The clinical and biological evolution of our patient was favourable with antibiotic treatmen
Neglected Pulmonary Arterial Hypertension in Sickle Cell Anaemia during Prenatal Care
Get PDFPulmonary arterial hypertension (PAH) is one of the main complications of sickle cell disease (SCD) and imparts significant risk during pregnancy. Here, we report the outcome of undetected PAH in a pregnant woman with SCD. The patient presented with severe progressive dyspnoea with echocardiographic findings of high pressure in the pulmonary artery in the 37th week of pregnancy. Despite an emergency caesarean section, both mother and neonate died. Regular cardiovascular check-up is essential for SCD patients and careful prenatal care should include cardiovascular evaluation. PAH during pregnancy is associated with high mortality and morbidity. As there is no proof that new advanced therapies decrease the risks, early diagnosis in pregnant patients with underlying disease, like sickle cell anaemia, is essential and termination of pregnancy should be considered
Kikuchi–Fujimoto Disease: Review of 11 Cases Diagnosed Over 10 Years at a Tertiary Care Hospital in Doha, Qatar
Get PDFIntroduction: Kikuchi-Fujimoto (KF) disease is a rare and self-limiting disorder of unknown aetiology characterized by cervical lymphadenopathy (CLN) and fever. The pathophysiology remains unclear and may be triggered by an infectious agent leading to a self-limiting autoimmune process. There are no confirmatory laboratory tests and lymph node biopsy is required to differentiate KF disease from other serious conditions. Materials and methods: We report 11 cases of KF disease diagnosed at Hamad General Hospital, Qatar, between 2006 to 2016. The diagnosis is based on clinical presentation, investigations and histopathological examination of lymph nodes. Results: All patients had painful neck swelling (average duration of 2.9 weeks) and 10 had fever (average duration of 3.2 weeks). Five patients developed mild leucopenia which resolved completely. HIV and tuberculosis (TB) screening including sputum for AFB, a PPD skin test and chest x-ray was done for all patients and came back negative. Autoimmune screening was done for all patients and excluded any rheumatological disease. Ultrasound and CT of the neck confirmed cervical lymphadenopathy. Except for hepatomegaly in one patient, CT scans of the chest and abdomen were negative for any lymphadenopathy or organomegaly (performed in seven patients). Diagnosis was confirmed on lymph node excision biopsy. Histopathological examination showed findings consistent with the diagnosis of histiocytic necrotizing lymphadenitis (KF disease).Conclusion: KF disease should be kept in mind for patients presenting with fever and CLN. Lymphoma, TB and autoimmune diseases like systemic lupus erythematosus should be excluded in such patients
Erythematous Papular Rash: A Dermatological Feature of COVID-19
Get PDFCOVID-19 is the clinical expression of the highly contagious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral infection. Most patients have mild symptoms, but a significant proportion have severe or critical disease, which can include cardiac injury, sepsis, acute kidney failure and respiratory failure. It is also worth highlighting the increasing number of reported COVID-19 cases with dermatological disease/manifestations. The cutaneous clinical spectrum is wide and includes maculopapular, urticarial, varicelliform and petechial rashes, pseudo perniosis, livedo reticularis, and pityriasis rosea-like, violaceous and pustular lesions. Until the physiological mechanism is fully understood, it is important to describe these manifestations, which could help identify a typical pattern. This report describes a cutaneous manifestation in a COVID-19 patient
Transient Type 1 Brugada Pattern without Ongoing Fever during COVID-19 Pneumonia
Get PDFPatients with COVID-19 pneumonia can develop heart problems and may also may be susceptible to proarrhythmia, virus-related issues such as fever, stress, electrolyte disturbance and adverse effects from the use of antiviral drugs. We report a transient Brugada-like ECG pattern without ongoing fever in a 57-year-old man, admitted with a diagnosis of COVID-19 pneumonia, who did not have syncope or a family history of sudden cardiac deat
Myxoedema Coma Masquerading as Acute Stroke
Get PDFThis report describes the management of a patient with myxoedema coma masquerading as an acute stroke (with or without ‘cold sepsis’). Myxoedema coma is an endocrine emergency occurring when physiological adaptations to untreated hypothyroidism are overwhelmed by an acute precipitant. Even promptly treated, it has an associated mortality of up to 50%
