«L’arte industriale sulla via del classicismo» : vicenda moderna di un’antica Venere da Ercolano
Come testimoniato dall\u2019esistenza di centinaia di repliche, quello della c.d. \u201cVenere che si slaccia il sandalo\u201d deve essere considerato tra i pi\uf9 diffusi e popolari tipi scultorei di et\ue0 ellenistica e romana: imitazioni e adattamenti ispirati a questo antico modello sono state prodotte in epoca moderna fin dal Rinascimento. Una rinnovata fase di questo successo, tra la fine del XIX e l\u2019inizio del XX sec., \ue8 marcata dalla diffusione di un gran numero di copie di una statuetta rinvenuta ad Ercolano nel 1757. Le origini di tale sviluppo possono essere ricondotte all\u2019attivit\ue0 di alcune fonderie artistiche napoletane - Chiurazzi, De Angelis e Sommer soprattutto - attive nella riproduzione di opere archeologiche provenienti dall\u2019area vesuviana. Attraverso questo caso studio, l\u2019articolo intende seguire l\u2019evoluzione dell\u2019\uabarte industriale sulla via del classicismo\ubb, considerando le sue implicazioni legate alla riproduzione, falsificazione e collezionismo di antichit\ue0, ma anche alla ricezione delle forme dell\u2019arte antica all\u2019interno della cultura visuale moderna.The s.c. \u201cSandalbinder Venus\u201d has to be considered one of the most widespread and popular sculptural types from Hellenistic and Roman-era, as testified by hundreds of replicas. Imitations and adaptations inspired by this ancient model have been produced in modern times since the Renaissance. Between the end of the XIX and the beginning of the XX century, the diffusion of a large number of copies of a statuette discovered in Herculaneum in 1757 marks a renewed success of the type. This development can be traced back to the activity of some Neapolitan art foundries \u2013 Chiurazzi, De Angelis and Sommer above all \u2013 operating in the reproduction of original archaeological works from the Vesuvian area. The analysis of this case study can contribute to understand the evolution of the \uabindustrial art on the path of classicism\ubb, considering implications related to the reproduction, forgery and antiquities collecting, but also to the reception of ancient art within modern visual culture
Management of locked volar radio-ulnar joint dislocation
Isolated volar dislocation of the distal radio-ulnar joint is an extremely rare lesion. Diagnosis is commonly missed. The authors report their experience about a case of an acute locked volar distal radio-ulnar joint dislocation. A correct clinical and radiological diagnosis was done in the Emergency Department, and a closed reduction was achieved only after an axillary block, after a first failed attempt under slight sedation. A K-wire blocking the prono-supination and a short removable forearm cast protected the reduction for 25 days. Two weeks after the removal of the immobilization, the patient presented a complete functional recovery, with full range of motion. The authors highlight the importance of the clinical and radiological findings: a dorsal dimple at the ulnar side leads to a high index of suspicion, and represent the most relevant aid in diagnosis, associated to a proper imaging assessment. Prompt management allows a minimally invasive approach and a rapid functional recovery
Median nerve injury caused by screw malpositioning in percutaneous scaphoid fracture fixation
An unusual complication of percutaneous fixation of a schapoid fracture in a 36-year-old man is described. After this surgery, the patient complained of numbness and tingling within the median nerve distribution and thenar weakness. An Electromyography showing moderate CTS had led to carpal tunnel decompression, which resulted unsuccessful. When the patient presented to us, both sensory and motor median nerve impairment were present, interfering with his professional activity. A computed tomography scan performed to assess the scaphoid screw position, showed that the screw had been placed volar to the scaphoid, adjacent to the median nerve. Surgery confirmed median nerve compression by the screw, especially during complete wrist extension. The surgical removal of the screw led to immediate improvement of both the motor and sensory functions of the nerve, with complete clinical restoration of nerve function and resolution of the symptoms 2 months postoperatively
HPV genotypes detected in the oropharyngeal mucosa of HIV-infected men who have sex with men in Northern Italy
The aim of this study was to investigate the epidemiological profile of HPV oropharyngeal infections in HIV-infected men who have sex with men. A total of 135 subjects were enrolled at the L. Sacco University Hospital (Milan, Italy) to evaluate their HPV oropharyngeal infection status at baseline and at a follow-up visit at least 12 months later. HPV DNA was detected from oropharyngeal swabs using an in-house nested PCR that amplifies a segment of the L1 gene. The PCR products were then sequenced and genotyped. A greater percentage of high-risk genotypes was identified compared to low-risk genotypes (13\ub77% vs. 6\ub79%, P < 0\ub705), and two uncommon alpha-HPV genotypes were detected, i.e. HPV-102 and HPV-114. HPV infection prevalence was 24\ub74% and the cumulative incidence was 24\ub71%. During the follow-up period, one case of HPV infection (HPV-33) persisted, while the overall rate of infection clearance was 58\ub73%. HPV oropharyngeal infection was widespread in the cohort examined, and most of the infections were transient and cleared within 12 months. These results may help to clarify the role of HPV in the oropharynx and may also improve our understanding of the need to implement preventive strategies in at-risk populations
Human papillomavirus detection in paraffin-embedded colorectal cancer tissues
Human papillomavirus (HPV) has a well-recognized aetiological role in the development of cervical cancer and other anogenital tumours. Recently, an association between colorectal cancer and HPV infection has been suggested, although this is still controversial. This study aimed at detecting and characterizing HPV infection in 57 paired biopsies from colorectal cancers and adjacent intact tissues using a degenerate PCR approach. All amplified fragments were genotyped by means of sequencing. Overall, HPV prevalence was 12.3 %. In particular, 15.8% of tumour tissues and 8.8% of non-cancerous tissue samples were HPV DNA-positive. Of these samples, 85.7% were genotyped successfully, with 41.7% of sequences identifying four genotypes of the HR (high oncogenic risk) clade Group 1; the remaining 58.3% of HPVgenotyped specimens had an unclassified \u3b2-HPV. Examining additional cases and analysing whole genomes will help to outline the significance of these findings
Measles surveillance activities in the Metropolitan Area of Milan during 2017-2018
Introduction In Italy, the transmission of measles is still endemic, and 7,919 cases were reported to the National Surveillance System between January 2017 and December 2018. Aim of this study is to report the results of the measles surveillance activities in the Metropolitan City of Milan from March 2017 to December 2018, and to evaluate the surveillance performance WHO indicators. Methods The Local Health Units (LHUs) carried out case investigations and collected specimens to send to the EpiSoMI Lab (Subnational Reference Laboratory, SRL) of the University of Milan for cases/outbreaks confirmation and genotyping performed according to the WHO Guidelines. Results Overall, 610 suspected measles cases were reported by the surveillance system of the Metropolitan City of Milan. A total of 439 out of 540 cases with adequate specimens were laboratory-confirmed by molecular and/or serological assays. Two-hundred and thirty-six cases were notified as sporadic and 203 as related to 94 outbreaks. The most confirmed cases were aged 15\u201339 years, almost all not vaccinated. Overall, 282 cases were genotype D8 and 118 genotype B3. The evaluation of a set of indicators to monitor the quality of surveillance activities demonstrated the proficiency of the EpiSoMI Lab. Conclusions A well-done investigation of cases and outbreaks by the surveillance local system, in a timely manner, in order to notify and investigate suspected cases and to laboratory confirm or discard cases is fundamental to reduce morbidity, to prevent further virus transmission and to achieve measles elimination
A software tool for estimation of burden of infectious diseases in Europe using incidence-based disability adjusted life years
The burden of disease framework facilitates the assessment of the health impact of diseases through the use of summary measures of population health such as Disability- Adjusted Life Years (DALYs). However, calculating, interpreting and communicating the results of studies using this methodology poses a challenge. The aim of the Burden of Commu
