Traumatic shock and electroshock: the difficult relationship between anatomic pathology and psychiatry in the early 20th century

In the conviction that a look at the past can contribute to a better understanding of the present in the field of science too, we discuss here two aspects of the relationship between early 20th century anatomic pathology and psychiatry that have received very little attention, in Italy at least. There was much debate between these two disciplines throughout the 19th century, which began to lose momentum in the early years of the 20th, with the arrival on the scene of schizophrenia (a disease histologically sine materia) in all its epidemiological relevance. The First World War also contributed to the separation between psychiatry and pathology, which unfolded in the fruitless attempts to identify a histopathological justification for the psychological trauma known as shell shock. This condition was defined at the time as a "strange disorder" with very spectacular symptoms (memory loss, trembling, hallucinations, blindness with no apparent organic cause, dysesthesias, myoclonus, bizarre postures, hemiplegia, and more), that may have found neuropathological grounds only some hundred years later. Among the doctors with a passed involvement in the conflict, Ugo Cerletti, the inventor of electroshock treatment, focused on the problem of schizophrenia without abandoning his efforts to identify its organic factors: if inducing a controlled electric shock, just like an experimentally-induced epileptic seizure, seems to allay the psychotic symptoms and heal the patient, then what happens inside the brain? In seeking histological proof of the clinical effects of electroconvulsive therapy ("the destruction of the pathological synapses"), and attempting to isolate molecules (that he called acroagonins) he believed to be synthesized by neurons exposed to strong electric stimulation, Cerletti extended a hand towards anatomic pathology, and took the first steps towards a neurochemical perspective. However his dedication to finding a microscopic explanation for schizophrenia - in the name of a "somatist" approach that, some years earlier, the psychiatrist Enrico Morselli had labelled "histomania" - was unable to prevent psychiatry from moving further and further away from anatomic pathology

Model of Care for Adolescents and Young Adults with Cancer: The Youth Project in Milan

Adolescents and young adults (AYA) with cancer form a particular group of patients with unique characteristics, who inhabit a so-called "no man's land" between pediatric and adult services. In the last 10\u2009years, the scientific oncology community has started to pay attention to these patients, implementing dedicated programs. A standardized model of care directed toward patients in this age range has yet to be developed and neither the pediatric nor the adult oncologic systems perfectly fit these patients' needs. The Youth Project of the Istituto Nazionale Tumori in Milan, dedicated to AYA with pediatric-type solid tumors, can be seen as a model of care for AYA patients, with its heterogeneous multidisciplinary staff and close cooperation with adult medical oncologists and surgeons. Further progress in the care of AYA cancer patients is still needed to improve their outcomes

Assessing the role of EO in biodiversity monitoring: options for integrating in-situ observations with EO within the context of the EBONE concept

The European Biodiversity Observation Network (EBONE) is a European contribution on terrestrial monitoring to GEO BON, the Group on Earth Observations Biodiversity Observation Network. EBONE’s aims are to develop a system of biodiversity observation at regional, national and European levels by assessing existing approaches in terms of their validity and applicability starting in Europe, then expanding to regions in Africa. The objective of EBONE is to deliver: 1. A sound scientific basis for the production of statistical estimates of stock and change of key indicators; 2. The development of a system for estimating past changes and forecasting and testing policy options and management strategies for threatened ecosystems and species; 3. A proposal for a cost-effective biodiversity monitoring system. There is a consensus that Earth Observation (EO) has a role to play in monitoring biodiversity. With its capacity to observe detailed spatial patterns and variability across large areas at regular intervals, our instinct suggests that EO could deliver the type of spatial and temporal coverage that is beyond reach with in-situ efforts. Furthermore, when considering the emerging networks of in-situ observations, the prospect of enhancing the quality of the information whilst reducing cost through integration is compelling. This report gives a realistic assessment of the role of EO in biodiversity monitoring and the options for integrating in-situ observations with EO within the context of the EBONE concept (cfr. EBONE-ID1.4). The assessment is mainly based on a set of targeted pilot studies. Building on this assessment, the report then presents a series of recommendations on the best options for using EO in an effective, consistent and sustainable biodiversity monitoring scheme. The issues that we faced were many: 1. Integration can be interpreted in different ways. One possible interpretation is: the combined use of independent data sets to deliver a different but improved data set; another is: the use of one data set to complement another dataset. 2. The targeted improvement will vary with stakeholder group: some will seek for more efficiency, others for more reliable estimates (accuracy and/or precision); others for more detail in space and/or time or more of everything. 3. Integration requires a link between the datasets (EO and in-situ). The strength of the link between reflected electromagnetic radiation and the habitats and their biodiversity observed in-situ is function of many variables, for example: the spatial scale of the observations; timing of the observations; the adopted nomenclature for classification; the complexity of the landscape in terms of composition, spatial structure and the physical environment; the habitat and land cover types under consideration. 4. The type of the EO data available varies (function of e.g. budget, size and location of region, cloudiness, national and/or international investment in airborne campaigns or space technology) which determines its capability to deliver the required output. EO and in-situ could be combined in different ways, depending on the type of integration we wanted to achieve and the targeted improvement. We aimed for an improvement in accuracy (i.e. the reduction in error of our indicator estimate calculated for an environmental zone). Furthermore, EO would also provide the spatial patterns for correlated in-situ data. EBONE in its initial development, focused on three main indicators covering: (i) the extent and change of habitats of European interest in the context of a general habitat assessment; (ii) abundance and distribution of selected species (birds, butterflies and plants); and (iii) fragmentation of natural and semi-natural areas. For habitat extent, we decided that it did not matter how in-situ was integrated with EO as long as we could demonstrate that acceptable accuracies could be achieved and the precision could consistently be improved. The nomenclature used to map habitats in-situ was the General Habitat Classification. We considered the following options where the EO and in-situ play different roles: using in-situ samples to re-calibrate a habitat map independently derived from EO; improving the accuracy of in-situ sampled habitat statistics, by post-stratification with correlated EO data; and using in-situ samples to train the classification of EO data into habitat types where the EO data delivers full coverage or a larger number of samples. For some of the above cases we also considered the impact that the sampling strategy employed to deliver the samples would have on the accuracy and precision achieved. Restricted access to European wide species data prevented work on the indicator ‘abundance and distribution of species’. With respect to the indicator ‘fragmentation’, we investigated ways of delivering EO derived measures of habitat patterns that are meaningful to sampled in-situ observations

The Changing Amazon Hydrological Cycle—Inferences From Over 200 Years of Tree‐Ring Oxygen Isotope Data

Changes to the Amazon hydrological cycle have important consequences for world's largest tropical forest, and the biodiversity it contains. However, a scarcity of long-term climate data in the region makes it hard to contextualize recent observed changes in Amazon hydrology. Here, we explore to what extent tree-ring oxygen isotope (δ18OTR) chronologies can inform us about hydrological changes in the Amazon over the past two centuries. Two δ18OTR records from northern Bolivia and the Ecuadorian Andes are presented. The Ecuador record spans 1799–2012 (n = 16 trees) and the Bolivia record spans 1860–2014 (n = 32 trees), making them the longest δ18OTR records from the Amazon, and among the most highly-replicated δ18OTR records from the tropics to date. The two chronologies correlate well at interannual and decadal timescales, despite coming from sites more than 1,500 km apart. Both δ18OTR records are strongly related to interannual variation in Amazon River discharge measured at Óbidos, and accumulated upwind precipitation, suggesting a common climatic driver. In both records a strong increase in δ18OTR was observed up until approximately 1950, consistent with positive trends in the few other existing δ18O proxy records from across the Amazon. Considering all possible drivers of this long-term increase, a reduction in rainout fraction over the basin driven by rising sea surface temperatures in the North Atlantic is suggested as the most likely cause. The upward trend in δ18OTR reverses over the past 1–2 decades, consistent with the observed strengthening of the Amazon hydrological cycle since approximately 1990

A patient with meningeal melanomatosis treated for periodontal disease with a bone regeneration procedure and dental implants: clinical and behavioral management to support medical compliance

During the last three decades dental implants have become increasingly used in partially edentulous periodontally compromised patients. The type of bacteria in the peri-implant sulcus is influenced by the periodontal bacteria present on the surfaces of the remaining teeth. Peri-implant sulci of partially edentulous individuals harbour more motile rods and spirochetes than those of fully edentulous individuals. If Peri-implantitis arises, it may lead to implant failure. This complication occurs more frequently in patients with poor oral hygiene. This is a site-specific bacterial infection similar to that caused by periodontal bacteria around teeth and it should be prevented. This study was conducted to radiographically evaluate hard tissue response around 6 implants, over a 2-year period, in a previously surgically treated patient affected by severe chronic periodontitis. Psychological considerations and behavioral management of the patient are described. A complex implant-perio-prosthodontic case of a 54-year-old man affected by meningeal melanomatosis with a history of generalized severe chronic periodontitis was recruited. A comprehensive periodontal examination around teeth was accomplished before periodontal and implant treatment. After diagnostic work-up, compromised teeth from 1.3 to 2.3 and from 3.2 to 4.2 were extracted. Tooth 1.7 was also extracted. Afterwards fixed provisional restoration rehabilitated all the natural dentition and the missing teeth. Endodonthic therapies were conducted on all the teeth due to high dentinal sensitivity and pre-prosthodontic crown reconstructions performed. Periodontal surgery with modified Widman flaps were then accomplished on all the teeth. Three months later four maxillary implants in position 1.3,1.1,2.1,2.3 and two mandibular implants in position 4.2,3.2 were inserted. During mandibular implants positioning, the mental mussels were isolated and detached to achieve proper guided bone regeneration. During implant surgery, due to systemic conditions concern, the patient underwent intravenous sedation. Five months later the implants and the teeth were rehabilitated with fixed metal-ceramic bridges. Regarding the upper prosthetic rehabilitation, the incisors marginal edges were kept vertical to the nasal spine, due to lack of previous reference points. According to the reference points previously determined, the difference in bone level between radiographs taken at implants insertion and at the maintenance appointments was calculated. The health of the periodontally treated teeth resulted greatly enhanced. The mean alveolar bore loss was 0,30 mm after a 2-year observation period. The control of the periodontal disease before implant insertion in patients with severe chronic periodontitis is of paramount importance, as well as a regular maintenance program is essential for the health of the periodontal and peri-implant tissues. The management of patients with complex needs requires a multidisciplinary team designed to meet all the patient’s needs on various levels
