Pietro Pacifico Gamondi (1914-1993), tropical physician and ethnologist. A protagonist of medical research in the middle of the 20th century.

Pietro Pacifico Gamondi was a tropical physician, who was one of the main protagonists of medical research during the 20th century. His training as a doctor first saw him in Rome following doctor Aldo Castellani. Gamondi then left for Lisbon, London, and the extra-European countries that have characterized his path as a doctor and as a man. In fact, he traveled to Indonesia and Africa, where took care of the population, combining European and local medicine. In this contribution, we wanted to remember the figure of a man who dedicates his life to tropical medicine and to the care of others.

Feasibility and acceptability of saliva-based testing for the screening of SARS-CoV-2 infection in prison.

Background: Saliva molecular tests have shown a similar sensitivity and specificity compared to nasopharyngeal test for SARS-CoV-2 diagnosis in both symptomatic and asymptomatic individuals. The SARS-CoV-2 pandemic affected Lombardy prisons, generating the need for extensive contact tracing activities and for detecting asymptomatic carriers. The availability of a less invasive test in a setting that hosts a high-risk and often hard-to-reach population, suggests its possible use in prisons. Methods: The study was carried out on a population of new incomers in Milan San Vittore pre-trial prison. All the new incomers were submitted to quarantine and to saliva test and nasopharyngeal swab (NPS) for SARS-CoV-2 detection at the entry and at the end of quarantine before their admission in community (Protocol 1-February 2nd to March 5th, 2021). Starting from March 8th to July 30th, 2021, the screening protocol was adjusted to avoid biases in sample collection (Protocol II), and saliva testing was performed at entrance. Results: 12/1,120 enrolled subjects were excluded from the study. Among the 1,080 processed samples, 1 tested positive, 5 weakly positive, 1,069 negative, 3 were invalid, and 2 samples tested positive for the viral gene N2 only, with Ct value above 38. During Protocol I, 6/156 coupled saliva/NPS tests were discordant due to food ingestion prior saliva collection, prompting us to establishing Protocol II. Conclusions: Saliva molecular testing is feasible in prison setting, being less invasive and easier to use, and reliable. Acceptability was very high even in a complex context as that of newly incarcerated persons.

Lithographic lecture notes. A tool of forensic medicine teaching. Observation on the lessons of Paolo Pellacani (1884-1885), forensic physician at the University of Pavia.

We focus our attention on the use of lithographed lecture notes written by professors, or more often by students, in the teaching of medicine and surgery courses, between the late 19th and early 20th centuries, a period in which, to better understand the phenomena underlying life and death, collaboration between medical professionals and natural science researchers was intense (1). In particular, we analyzed the lithographed lecture notes of Professor Paolo Pellacani at the University of Pavia for the course of legal medicine.
