Bones of recent mammals in the Amboseli Basin, southern Kenya, exhibit distinctive weathering characteristics that can be related to the time since death and to the local conditions of temperature, humidity and soil chemistry. A categorization of weathering characteristics into six stages, recognizable on descriptive criteria, provides a basis for investigation of weathering rates and processes. The time necessary to achieve each successive weathering stage has been calibrated using known-age carcasses. Most bones decompose beyond recognition in 10 to 15 yr. Bones of animals under 100 kg and juveniles appear to weather more rapidly than bones of large animals or adults. Small-scale rather than widespread environmental factors seem to have greatest influence on weathering characteristics and rates. Bone weathering is potentially valuable as evidence for the period of time represented in recent or fossil bone assemblages, in- cluding those on archeological sites, and may also be an important tool in censusing populations of animals in modern ecosystems.

les tonneaux de vin ou de bière, du bout des doigts pour estimer le niveau du liquide restant après soutirage. Mais cette observation en serait sans doute restée là, si le médecin n’avait eu l’oreille exercée d’un mélomane. Pratiquée durant près de deux siècles, la percussion a été supplantée par l’échographie, qui, en somme est à la percussion ce que le Concorde est à l’avion de Blériot ou la guitare électrique à la mandoline... Le souvenir de ce médecin mélomane vaut d’être mieux connu qu’il ne l’est en France. En effet, si la percussion d’un objet quelconque pour en apprécier la densité est une pratique qui remonte vraisemblablement à la plus haute Antiquité, sans doute a-t-il été nécessaire d’attendre la conjonction, chez un médecin, d’un sens aigu de l’observation et de qualités musicales particulièrement développées pour que soit mise au point la percussion. Homme d’une grande culture autant que modeste, fort attaché à sa famille et dont le caractère bienveillant se situait totalement à l’opposé de la personnalité d’un Morgagni, Auenbrugger fut à la fois un praticien dévoué à ses patients, qui apporta une contribution importante à l’essor de la médecine et un mélomane dont les talents artistiques permirent la découverte de la percussion et ouvrirent la voie à la méthode anatomoclinique.

During the twentieth century, the development of orthopaedic surgery led to a more solid definition of the orthopaedist’s boundaries and competences. It started at the beginning of the 1900 from Alessandro Codivilla’s intuition, and his stating that the orthopaedist had to deal with the diseases of the musculoskeletal system [1]. However, the main pathologies involving orthopaedists in the first few years of last century were the congenital and childhood ones, those resulting from poliomyelitis, and the bone complications of tuberculosis. Later on, the treatment of degenerative diseases focused mainly on the treatment of coxoarthritis, among which the worth mentioning are consequences of congenital dysplasias, and knee arthritis. Up until the 1960s, arthritis surgery mainly consisted of osteotomies, with the aim of modifying the axes and the load areas of the joint cartilage, and arthrodeses, which inevitably led to poor functional results in large joints, even though it acted directly upon the cause of the arthritic pain. In 1962, Sir John Charnley described his hip prosthesis, thus changing the approach to degenerative surgery for ever [2]. In parallel, only after several attempts, John Insall improved the knee prosthesis with a condylar design in the 1970s [3]. Interestingly, in about a decade the approach to the treatment of coxoarthritis changed completely in the records of the national congress of the Italian Society of Orthopaedics and Traumatology (SIOT). In the 49th Congress in 1964 on the surgical treatment of coxoarthritis, osteotomies, arthrodeses, and many interventions on the soft parts were the pillars of the orthopaedist’s cultural background, while more modern therapies such as acetabuloplasties and arthroplasties were only beginning to develop. In 1969, many orthopaedists already reported on their experience in prosthetic implants, and the scientific community was split between “conservatives and prosthesisizers”. Since then, the development of more and more sophisticated prosthetic implants has characterized orthopaedic surgery, which nowadays faces the issue of revision surgery and complication management [4]. Another innovation in the treatment of degenerative conditions has certainly been the implementation of arthroscopic techniques of the large joints, which has been widely considered as a technological innovation of the last few years, even though a 1912 contribution from Severin Nordentoft has just been found: at the 41st congress of the German Surgery Society in Berlin he presented his contribution on laparoscopy, cystoscopy, and knee endoscopy, followed after a few years by Takagi (from Japan), and Bircher (from Switzerland), who mainly concentrated on joint endoscopy [5]. Finally, the last few years have seen a growing interest in new treatment approaches towards degenerative arthritis, through the implementation of bioengineering in surgery, in particular with studies on osteocartilage transplants, mesenchymal cells, biomaterials, and growth factors.

Abstract Objective  In this study, we evaluated the safety of early discharge (ED) of newborns born to coronavirus disease 2019 (COVID-19)-positive mothers. Study Design  All ED newborns from the postpartum wards of the Fondazione Policlinico Gemelli between January 1, 2022, and February 28, 2022, were retrospectively analyzed. Newborns from mothers with COVID-19 and those from uninfected mothers were considered. The primary outcome was to evaluate whether the rate of the composite outcome, which was the percentage of rehospitalization/access in emergency room (RH/ER) within the first week from discharge, differed between neonates born to mother with COVID-19 (COVID-19 group) and those born to uninfected mothers (no COVID-19 group). The secondary outcomes were to assess the quality of feeding and number of outpatient visits in the follow-up clinic between the two cohorts of patients. Results  One hundred and thirty-four newborns in the no COVID-19 group and 26 in the COVID-19 group were analyzed. The rate of RH/ER in the no COVID-19 group was of 6 over 134 newborns (0.045, 95% confidence image [CI]: 0.017–0.095), while in COVID-19 group, it was of 2 over 26 newborns (0.077), which does not differ from the expected rate (1.17 over 26 newborns, 0.045, 95% CI: 0.017–0.095). Conclusion  ED for newborns from mothers with COVID-19 could be an actionable safe strategy. Key Points We evaluated the feasibility of early discharge (ED) of mothers with COVID-19 and their newborns. Rate of rehospitalization between newborns from uninfected mothers and infected ones was comparable. ED could be an actionable practice for newborns from mothers with COVID-19.
