Informal caregivers of individuals affected by psychotic disorder can play a key role in the recovery process. However, little research has been conducted on the lived experiences of carers and family members. We conducted a bottom-up (from lived experience to theory) review of first-person accounts, co-written between academics and experts by experience, to identify key experiential themes. First-person accounts of carers, relatives, and individuals with psychosis were screened and discussed in collaborative workshops involving individuals with lived experiences of psychosis, family members, and carers, representing various organizations. The lived experiences of family members and carers were characterized by experiential themes related to dealing with the unexpected news, the search for a reason behind the disorder, living with difficult and negative emotions, dealing with loss, feeling lost in fragmented healthcare systems, feeling invisible and wanting to be active partners in care, struggling to communicate with the affected person, fighting stigma and isolation, dealing with an uncertain future, and learning from one's mistakes and building resilience and hope. Our findings bring forth the voices of relatives and informal carers of people with psychosis, by highlighting some of the common themes of their lived experiences from the time of the initial diagnosis and throughout the different clinical stages of the disorder. Informal carers are key stakeholders who can play a strategic role, and their contributions in the recovery process merit recognition and active support by mental health professionals., (© 2023 The Author(s).

Background: Influenza seasonality has been frequently studied, but its mechanisms are not clear. Urban in-situ studies have linked influenza to meteorological or pollutant stressors. Few studies have investigated rural and less polluted areas in temperate climate zones., Objectives: We examined influences of medium-term residential exposure to fine particulate matter (PM 2.5 ), NO 2 , SO 2 , air temperature and precipitation on influenza incidence., Methods: To obtain complete spatial coverage of Baden-Württemberg, we modeled environmental exposure from data of the Copernicus Atmosphere Monitoring Service and of the Copernicus Climate Change Service. We computed spatiotemporal aggregates to reflect quarterly mean values at post-code level. Moreover, we prepared health insurance data to yield influenza incidence between January 2010 and December 2018. We used generalized additive models, with Gaussian Markov random field smoothers for spatial input, whilst using or not using quarter as temporal input., Results: In the 3.85 million cohort, 513,404 influenza cases occurred over the 9-year period, with 53.6% occurring in quarter 1 (January to March), and 10.2%, 9.4% and 26.8% in quarters 2, 3 and 4, respectively. Statistical modeling yielded highly significant effects of air temperature, precipitation, PM 2.5 and NO 2 . Computation of stressor-specific gains revealed up to 3499 infections per 100,000 AOK clients per year that are attributable to lowering ambient mean air temperature from 18.71 °C to 2.01 °C. Stressor specific gains were also substantial for fine particulate matter, yielding up to 502 attributable infections per 100,000 clients per year for an increase from 7.49 μg/m 3 to 15.98 μg/m 3 ., Conclusions: Whilst strong statistical association of temperature with other stressors makes it difficult to distinguish between direct and mediated temperature effects, results confirm genuine effects by fine particulate matter on influenza infections for both rural and urban areas in a temperate climate. Future studies should attempt to further establish the mediating mechanisms to inform public health policies., (© 2022. The Author(s).)

Purpose of Review: Nuclear medicine has the potential to explore and illuminate several pathways in breast cancer (BC) offering different radiopharmaceuticals for positron emission tomography (PET) designed to target specific tumor characteristics. The aim of this critical review is to give an overview about emerging opportunities in PET imaging, underlining the future potential contribution in the management of BC patients., Recent Findings: Beside 2-deoxy-2-[ 18 F]-fluoro- d -glucose (FDG), new generation tracers for PET imaging have been recently proposed to investigate specific characteristics in breast cancer, both targeting tumor cells and the tumor micro-environment (TME)., Summary: FDG-PET is a procedure that received extensive clinical validation. However, its role in BC is still suboptimal due to the low-FDG avidity of specific tumor subtypes. Human epidermal growth receptor-2 and integrin targeted PET radiotracers might provide useful information selecting patients more likely to respond to target therapy. FluoroEstradiol (FES) is a FDA-approved PET radiotracer targeting the estrogen receptor (ER), useful to investigate metastatic ER+ patients, to assess in vivo ER heterogeneity and to evaluate hormonal therapy efficacy. Inhibitors of the fibroblast activation protein (FAPi) targeting the cancer-associated fibroblast can explore the TME with PET imaging. FAPi is also proposed a theranostic agent for radio-ligand therapy., (Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.)

Background: The aim of this study was to evaluate the possible presence of diastolic dysfunction and its possible effects in terms of respiratory mechanics, gas exchange and lung recruitability in mechanically ventilated ARDS., Methods: Consecutive patients admitted in intensive care unit (ICU) with ARDS were enrolled. Echocardiographic evaluation was acquired at clinical PEEP level. Lung CT-scan was performed at 5 and 45 cmH 2 O. In the study, 2 levels of PEEP (5 and 15 cmH 2 O) were randomly applied., Results: A total of 30 patients were enrolled with a mean PaO 2 /FiO 2 and a median PEEP of 137 ± 52 and 10 [9-10] cmH 2 O, respectively. Of those, 9 patients (30%) had a diastolic dysfunction of grade 1, 2 and 3 in 33%, 45% and 22%, respectively, without any difference in gas exchange and respiratory mechanics. The total lung weight was significantly higher in patients with diastolic dysfunction (1669 [1354-1909] versus 1554 [1146-1942] g) but the lung recruitability was similar between groups (33.3 [27.3-41.4] versus 30.6 [20.0-38.8] %). Left ventricular ejection fraction (57 [39-62] versus 60 [57-60]%) and TAPSE (20.0 [17.0-24.0] versus 24.0 [20.0-27.0] mL) were similar between the two groups. The response to changes of PEEP from 5 to 15 cmH 2 O in terms of oxygenation and respiratory mechanics was not affected by the presence of diastolic dysfunction., Conclusions: ARDS patients with left ventricular diastolic dysfunction presented a higher amount of lung edema and worse outcome.

In this paper, the conceptual aspects of the CAREPATH project, in terms of technical and clinical requirements and considerations, are presented.

Psychosis is the most ineffable experience of mental disorder. We provide here the first co-written bottom-up review of the lived experience of psychosis, whereby experts by experience primarily selected the subjective themes, that were subsequently enriched by phenomenologically-informed perspectives. First-person accounts within and outside the medical field were screened and discussed in collaborative workshops involving numerous individuals with lived experience of psychosis as well as family members and carers, representing a global network of organizations. The material was complemented by semantic analyses and shared across all collaborators in a cloud-based system. The early phases of psychosis (i.e., premorbid and prodromal stages) were found to be characterized by core existential themes including loss of common sense, perplexity and lack of immersion in the world with compromised vital contact with reality, heightened salience and a feeling that something important is about to happen, perturbation of the sense of self, and need to hide the tumultuous inner experiences. The first episode stage was found to be denoted by some transitory relief associated with the onset of delusions, intense self-referentiality and permeated self-world boundaries, tumultuous internal noise, and dissolution of the sense of self with social withdrawal. Core lived experiences of the later stages (i.e., relapsing and chronic) involved grieving personal losses, feeling split, and struggling to accept the constant inner chaos, the new self, the diagnosis and an uncertain future. The experience of receiving psychiatric treatments, such as inpatient and outpatient care, social interventions, psychological treatments and medications, included both positive and negative aspects, and was determined by the hope of achieving recovery, understood as an enduring journey of reconstructing the sense of personhood and re-establishing the lost bonds with others towards meaningful goals. These findings can inform clinical practice, research and education. Psychosis is one of the most painful and upsetting existential experiences, so dizzyingly alien to our usual patterns of life and so unspeakably enigmatic and human., (© 2022 World Psychiatric Association.)

Summary: Background. ARPA Piemonte carries out occupational exposure measurements of chemical agents in workplace environment to support the Occupatonal Health and Safety Units of Local Health Boards for the assessment of the exposure level of dangerous chemical. Data are reported in internal documents, but are not available for other purposes. Objectives. Organize the occupational exposure measures collected by ARPA Piemonte, in order to facilitate their availability, in accordance with the indications of the European Foundation for the Improvement of Living and Working Conditions. Methods. An application in a relational database environment was defined and developed to collect and structure information relating to companies, interventions, tasks and / or monitored sampling points, samples and measurements performed. Results. Data on chemical exposure related to interventions carried out by ARPA Piemonte in the period from 2005 to part of 2020 have been collected in the ESP ALP application. ESP ALP contains information about 161 companies, 193 interventions, 815 sampling points, 3.490 samples and 18.576 measurements and information on companies obtained from the 2011 Census of Economic Activities and the archives of the National Institute for Insurance against Accidents at Work (INAIL). Discussion. We verified the feasibility of retrieving and organizing the information collected in past years in an integrated environment that facilitates its processing and use. Finally, we confirm the usefulness of collaboration between multidisciplinary professionals., Competing Interests: The authors of this article have no conflict of interests to disclose., (Copyright© by GIMLE.)

Background: The latest National Comprehensive Cancer Network Breast Cancer Guidelines still discourage repeat sentinel node biopsy (SNB) after mastectomy, and the largest multicentric study available reports only 35 cases in the absence of previous axillary dissection (AD)., Methods: From January 2003 to November 2018, 89 patients of the European Institute of Oncology with local recurrence of breast cancer after mastectomy, free of distant metastases, with a clinically negative axilla and a negative axillary ultrasound, in absence of AD, underwent lymphatic mapping before wide local excision., Results: During surgery, SNB was successful for 99% of the patients, with 14% being metastatic. Additional metastatic nodes removed by AD after a positive sentinel node occurred in 82% of cases. After a medium follow-up period of 3.7 years, the overall survival rate was 96.7%, and the disease-free survival rate was 84.4%. No axillary relapse after AD was recorded. One patient who refused human epidermal growth factor receptor 2 (HER2)-targeted treatment experienced ipsilateral axillary recurrence after a negative repeat SNB. The first axillary level was never directly irradiated because all the patients with positive repeat SNB underwent AD. For invasive luminal-like HER2-negative recurrences, the metastatic sentinel node was significantly associated with the choice to prescribe adjuvant chemotherapy (p = 0.003)., Conclusions: In specialized centers, repeat axillary SNB for patients with local recurrence after mastectomy in the absence of previous AD can represent a safe option for detection and removal of occult axillary disease that would otherwise not be excised/irradiated to achieve better local control and could possibly influence the choice of adjuvant treatments., (© 2021.

The tumor microenvironment (TME) surrounding tumor cells is a complex and highly dynamic system that promotes tumorigenesis. Cancer-associated fibroblasts (CAFs) are key elements in TME playing a pivotal role in cancer cells' proliferation and metastatic spreading. Considering the high expression of the fibroblast activation protein (FAP) on the cell membrane, CAFs emerged as appealing TME targets, namely for molecular imaging, leading to a pan-tumoral approach. Therefore, FAP inhibitors (FAPis) have recently been developed for PET imaging and radioligand therapy, exploring the clinical application in different tumor sub-types. The present review aimed to describe recent developments regarding radiolabeled FAP inhibitors and evaluate the possible translation of this pan-tumoral approach in clinical practice. At present, the application of FAPi-PET has been explored mainly in single-center studies, generally performed in small and heterogeneous cohorts of oncological patients. However, preliminary results were promising, in particular in low FDG-avid tumors, such as primary liver and gastro-entero-pancreatic cancer, or in regions with an unfavorable tumor-to-background ratio at FDG-PET/CT (i.e., brain), and in radiotherapy planning of head and neck tumors. Further promising results have been obtained in the detection of peritoneal carcinomatosis, especially in ovarian and gastric cancer. Data regarding the theranostics approach are still limited at present, and definitive conclusions about its efficacy cannot be drawn at present. Nevertheless, the use of FAPi-based radio-ligand to treat the TME has been evaluated in first-in-human studies and appears feasible. Although the pan-tumoral approach in molecular imaging showed promising results, its real impact in day-to-day clinical practice has yet to be confirmed, and multi-center prospective studies powered for efficacy are needed.

Aims: The clinical significance of nonvisualized sentinel lymph nodes (non-vSLNs) is unknown. The authors sought to determine the incidence of non-vSLNs on lymphoscintigraphy, the identification rate during surgery, factors associated with non-vSLNs and related axillary management. Patients & methods:  A total of 30,508 consecutive SLN procedures performed at a single institution from 2000 to 2017 were retrospectively studied. Associations between clinicopathological factors and the identification of SLNs during surgery were assessed. Results: Non-vSLN occurred in 525 of the procedures (1.7%). In 73.3%, at least one SLN was identified intraoperatively. Nodal involvement was only significantly associated with SLN nonidentification (p < 0.001). Conclusion: Patients with non-vSLN had an increased risk for SLN metastasis. The detection rate during surgery was consistent, reducing the amount of unnecessary axillary dissection.

Background: Workplace injuries in Italy still occur despite laws and safety norms. We need to understand the causes rooted in the context and social conditions, and need to improve the practice of Occupational Safety and Health (OSH) inspectors of the Workplace Safety and Prevention Services (WSPS) of the Italian regional health boards. The aims of this study were to describe the setting up of a Community of Practice (CoP) for the production of best practices for injury prevention and to evaluate the motivation of OSH inspectors for participating in the CoP and the effects of CoP participation on their professional practice., Methods: Two workplace injury stories underwent peer review during each CoP meeting. We evaluated the CoP using a focus group and a questionnaire., Result: Between 2014 and 2021, the CoP met in 18 workshops. Over the 8-year period, the CoP grew from 20 to 150 participants. Overall, 30 stories underwent peer review and were published on the institutional website. The focus group participants stated that the reasons why they participated in the CoP were the need to share experience and to tackle new challenges., Conclusion: The CoP was found to be useful for improving professional practice by strengthening professional identity and contributing to the production of new knowledge.

Although empowerment is a widely used concept in health-related areas, its definition remains unclear. While there is evidence for the effectiveness of empowerment interventions in improving some psychosocial factors linked to health (e.g. patient self-care strategy, coping skills, access and effective use of health services) and some health outcomes like mental health and HIV/AIDS-related behaviour, other data appear to contradict this. Moreover, concepts, measures, and outcomes related to empowerment are operationalized in different ways. Using the case of tobacco control programmes, we wanted to explore: (a) how research on smoking reduction/prevention has conceptualized empowerment; (b) which measures and instruments have been used to assess behaviour outcomes and the empowerment process. We hypothesized that the transformative potential that characterizes empowerment is marginally considered.A total of 18 studies reporting on the effect of prevention interventions on smoking and/or empowerment outcomes were reviewed. Two kinds of study were distinguished: (a) studies reporting behaviour outcomes without data about the impact on empowerment; (b) studies analysing the empowerment process. Among this latter type, some studies did not provide information about the specific behaviour (smoking), while others examined the impact of intervention on both smoking and empowerment. In about half of all studies, empowerment strategies were found to be effective in improving smoking outcomes, while no differences were found between intervention and control groups in the remaining studies. The present review suggests that pragmatic definitions of empowerment need to be developed in order to promote its transferability and evaluation.

Objective: The aim of this case series is to describe our experience in diagnosis and management of oncological asymptomatic patients with COVID-19 who underwent 18 F-FDG PET/CT., Methods: From March 9 to March 31, 2020, we identified 5 patients who had PET/CT findings suspicious for COVID-19, but no symptom of infection., Results: The first three patients were administered an SARS-CoV-2 test in a COVID-dedicated center, while the fourth and fifth were tested in our institution, in accordance with a new internal procedure. The SARS-CoV-2 test yielded positive results in all five patients., Conclusion: In this COVID-19 emergency, our task as radiologists and nuclear medicine physicians is to be able to identify imaging findings suggestive of the disease and to manage patients without overloading the hospital system.

Multiple synchronous (multifocal or multicentric) ipsilateral breast cancers with heterogeneous histopathology are a rare clinical occurrence, however, their incidence is increasing due to the use of MRI for breast cancer screening and staging. Some studies have demonstrated poorer clinical outcomes for this pattern of breast cancer, but there is no evidence to guide clinical practice. In this multidisciplinary review, we reflect on pathology and molecular characteristics, imaging findings, surgical management including conservation and reconstructive options and approach to the axilla, and the role of chemotherapy and radiotherapy. Multidisciplinary discussions appear decisive in planning an appropriate surgical choice and defining the correct systemic treatment tailored to each clinical condition.

Background: To assess the clinical usefulness of serum tumor markers for early detection of distant breast cancer recurrence using FDG-PET/CT., Methods: We retrospectively analyzed 561 consecutive patients who underwent surgery for invasive primary breast cancer and had increased tumor markers (CA 15-3 and CEA) after completion of locoregional therapy. FDG-PET/CT data were reviewed for all cases. CA 15-3 and CEA were evaluated both in a continuous and in a quartile (Q) distribution. The Wilcoxon rank-sum test and logistic regression models were used to evaluate the association between increased tumor marker values and the presence (and type) of distant metastases., Results: The median value of CA 15-3 was 35.0 U/mL (IQR, 29.5-43.0) in cases where no distant metastases were detected, and it was 58.9 U/mL (IQR, 40.0-108.0) in cases where metastases were detected (p < 0.001). The median value of CEA was 6.6 U/mL (IQR, 4.4-10.0) in cases of no metastases and 12.4 U/mL (IQR, 6.9-30.0) in cases of metastases (p < 0.001). Increased levels of both tumor markers (Q3 and Q4) were strongly associated with the presence of distant metastases. The association between CA 15-3 and bone/liver metastases was stronger compared with other types of metastases (p heterogeneity between odds ratios [ORs] = 0.03 for Q3 and <0.001 for Q4), while no relevant heterogeneity between ORs emerged for CEA., Conclusion: Increased tumor marker levels detected in asymptomatic breast cancer patients during adjuvant therapies and follow-up are significantly predictive of distant metastases identified on FDG-PET/CT., (© 2020 S.

Oesophageal cancer is an aggressive disease. The possibility to early stratify patients as responsive and non-responsive with a non-invasive method is extremely appealing. The uptake of Fluorodeoxyglucose ( 18 F-FDG) in tumours, provided by positron emission tomography (PET) images, has been proved to be useful to assess the initial staging of the disease, recurrence, and response to chemotherapy and chemo-radiotherapy (CRT). In the last years, efforts have been focused on the possibility to use ad interim 18 F-FDG-PET/CT (PET int ) to evaluate response during radiation therapy. However, controversial findings have been reported, although some relevant results would support its use for individual therapeutic decision. The present review assembles the comprehensive literature of the last decade to evaluate whether and in which cases PET int may offer predictive potential in oesophageal cancer. All the analysed studies (13 studies, 697 patients) denoted PET int as a challenging examination for early assessment of outcomes during CRT. In particular, 8 studies advocated the predictivity of PET int , whilst 5 did not find any correlation between the interim variation of PET parameters and the pathological complete response and/or the clinical outcome. The reasons that possibly have caused contradictions among the studies demand further research with prospective and uniform protocols and methods of analysis to assess the predictive and prognostic value of PET int in oesophageal cancer., (Copyright © 2017 Elsevier B.V.

Background: Non-Small Cell Lung Cancer (NSCLC) is characterized by aggressiveness and includes the majority of thorax malignancies. The possibility of early stratification of patients as responsive and non-responsive to radiotherapy with a non-invasive method is extremely appealing. The distribution of the Fluorodeoxyglucose ( 18 F-FDG) in tumours, provided by Positron-Emission-Tomography (PET) images, has been proved to be useful to assess the initial staging of the disease, recurrence, and response to chemotherapy and chemo-radiotherapy (CRT)., Objectives: In the last years, particular efforts have been focused on the possibility of using ad interim 18 F-FDG PET (FDG int ) to evaluate response already in the course of radiotherapy. However, controversial findings have been reported for various malignancies, although several results would support the use of FDG int for individual therapeutic decisions, at least in some pathologies. The objective of the present review is to assemble comprehensively the literature concerning NSCLC, to evaluate where and whether FDG int may offer predictive potential., Methods: Several searches were completed on Medline and the Embase database, combining different keywords. Original papers published in the English language from 2005 to 2016 with studies involving FDG int in patients affected by NSCLC and treated with radiation therapy or chemo-radiotherapy only were chosen., Results: Twenty-one studies out of 970 in Pubmed and 1256 in Embase were selected, reporting on 627 patients., Conclusion: Certainly, the lack of univocal PET parameters was identified as a major drawback, while standardization would be required for best practice. In any case, all these papers denoted FDG int as promising and a challenging examination for early assessment of outcomes during CRT, sustaining its predictivity in lung cancer.

Positron emission tomography (PET) is an imaging modality widely applied in oncology for tumor staging, volume delineation in radiation therapy planning, and therapy response assessment. F-18 fluorodeoxyglucose (FDG) PET combined with computed tomography plays a significant role in the management of locally advanced head and neck cancer patients in the pretreatment setting to predict outcome and prognosis and after chemoradiation therapy (CRT) to assess tumor response. This review aims to evaluate the use of FDG PET acquired during CRT, ad interim FDG (FDG int ), to identify tumor response at an early stage, modify the treatment plan if necessary, or set up alternative strategies to enhance the therapeutic ratio. Most of the studies confirmed the value of FDG int in predicting the response to CRT, whereas a few highlighted the poor predictive value of FDG int compared with FDG acquired 2 to 4 months after the end of CRT, which was well correlated with local and regional control and survival. Such findings deserve to be further analyzed in more homogeneous series with greater patient numbers according to the tumor site and CRT schedules. The best time to assess tumor response during radiation therapy remains a matter of debate, although 2 weeks seems most favorable, still providing the opportunity to adapt the treatment strategy., (Copyright © 2017 Elsevier Inc.

Background: Occupational Health and Safety (OSH) inspectors of the Health Units of Piedmont Region wrote 47 case histories based on data gathered from injury investigations as part of the project "From the injury investigation reports to case histories: creation of a collection of case histories on occupational injuries". Afterwards a Community of Practice (CoP) was initiated with the aim of sharing recommendations for prevention of occupational injuries., Objective: The aims of the article are: 1) to describe the implementation process of the CoP; 2) to evaluate the benefits of CoP regarding the improvement of professional practice of OSH inspectors., Methods: Two injury case histories were peer reviewed during each meeting of the CoP. A focus group was set up to evaluate benefits of CoP. Seven OSH inspectors participated in this focus group., Results: Eight CoP meetings were organized and about 70 OSH inspectors participated. Fourteen stories were peer reviewed and eight were published on www.dors.it. Operators involved in the focus groups reported that the main reasons for participation in the CoP were the need to compare and tackle new challenges. The criticalities are tied to the turnover of the participants and to the lack of recognition by management. Most of the operators felt it was too early to include professionals such as Workers' Safety Representatives and Prevention and Safety Service Managers in the CoP due to their different professional roles., Conclusions: OSH inspectors reported professional benefits of CoP experience. We believe that this approach might be transferred, integrated and developed in other regions and included in the next national prevention plan.

18 F-fluorodeoxyglucose PET/CT ( 18 F-FDG-PET/CT) is widely applied in oncology for disease staging, assessment of therapy response, relapse diagnosis, follow-up and target volume delineation. In particular, it can detect early response during chemoradiotherapy (interim) because functional modifications usually precede morphological ones. This ability is crucial to the radiation oncologist for the management of patients, to avoid persisting with ineffective therapy - often leading toxicity - and to shift to potentially more effective alternatives. Interim 18 F FDG-PET imaging in rectal and cervical cancer, the main malignancies of the pelvic district, has been applied and a broad literature is available, although some results are discordant. This systematic review summarizes the application of 18 F FDG-PET/CT during the chemoradiotherapy of locally advanced pelvic malignancies in order to clarify its capability to predict response and prognosis and its potential role to tailor therapy, which seems to be validated in rectal cancer, whilst less conclusive in cervical cancer., (Copyright © 2017 Elsevier B.V.

A 52-year-old man underwent Ga DOTATOC PET/CT scan for postsurgical staging of a neuroendocrine tumor of the lung. The PET images showed a single focus of increased activity in a soft tissue nodule located posteriorly to a cervical vertebra. Surgical removal of the lesion led to the histological diagnosis of retiform hemangioendothelioma.

Aim: To assess the sentinel-node identification rate at lymphoscintigraphy and its technical feasibility after neo-adjuvant treatments., Material of Study: Between 2000 and 2013, 444 consecutive patients affected by primary locally advanced breast cancer were enrolled in this study. All individuals were candidate for neo-adjuvant treatments and for lymphoscintigraphy before surgery., Results: The median age was 44 years at onset; almost one sentinel node was identified during lymphoscintigraphy in 430 cases. The detection rate at lymphoscintigraphy was 96.9% (95% CI, 94.8-98.1%). Considering the correlation between specific treatments and sentinel node identification rate, we verified that the detection rate did not vary significantly (p=0.53) according to the type of neo-adjuvant therapies administered to the patients., Conclusions: Our results demonstrated that lymphoscintigraphy for sentinel node identification is a safe and feasible procedure after neo-adjuvant therapies, independently of treatment types., Key Words: Breast Cancer, Neo-Adjuvant Treatment, Sentinel lymphnode biopsy, Lymphoscintigraphy.

Isolated splenic metastases from solid malignancies are very rare. We report the case of a 58-year-old woman with isolated metachronous splenic metastasis from colon cancer detected 18 months after colectomy. F-FDG PET/CT allowed its recognition and guided the therapeutic approach toward surgery.

We describe the FDG PET/CT findings in an exceedingly rare case of metastatic pilomatrix carcinoma (PC). A 76-year-old man, who underwent incisional biopsy of a soft-tissue mass in the frontal scalp that revealed PC, was referred for an F-FDG PET/CT scan for staging purposes. PET/CT showed areas of increased radiotracer uptake corresponding to frontal mass and unsuspected lung lesions, which were later confirmed as metastases from PC at histological analysis. Clinical condition deteriorated rapidly, and the patient died 3 months after the initial diagnosis.

A 79-year-old man underwent F-choline PET/CT for biochemical recurrence of prostate cancer. PET/CT images showed an area of elevated radiopharmaceutical uptake in a left pelvic node. In addition, a small focus of increased radiolabeled choline accumulation was seen in a small nodule of the right breast, which was later histologically characterized as an infiltrating ductal carcinoma. In this patient, choline PET/CT was critical in localizing prostate cancer recurrence and identifying a second unsuspected malignancy.

Background: Many authors consider narrative descriptions of injuries gathered by OSH inspectors extremely important in identifying causes, setting priorities and drawing up intervention strategies. Narratives provide additional insight regarding complex behaviour, attitudes and interactions, which help to understand the decision patterns and the context of the injury. Storytelling is an effective way of sharing and remembering information., Objective: The main aim was to describe the experience of collecting stories from injury investigation reports, backed up by systematic prevention guidelines, that will improve information sharing by means of a knowledge transfer method based on storytelling., Methods: OSH operators from Health Units, who were invited to provide the injury stories, were enrolled through educational workshops aimed at selecting the injuries to relate following the sentinel event approach, using an effective style of writing, identifying the key elements of the story and using witnesses' narratives to study in depth the critical points identified during the investigation., Results: 110 OSH operators voluntarily joined the project between 2012 and first half of 2015. 33 injury stories were collected, discussed and published on Dors' website http://www.dors.it/storiedinfortunio., Conclusions: The results show that prevention and protection measures do indeed benefit from a narrative-based approach, so that health and safety can be viewed in a more comprehensive way by facilitating knowledge improvement and sharing.

Objective: The aim of the present study is to evaluate the accuracy of Positron Emission Tomography/Computed Tomography (PET/CT) with Fluorodeoxyglucose ([18F]FDG) to predict treatment response in patients with locally advanced rectal cancer (LARC) during neoadjuvant chemoradiotherapy., Patients and Methods: Forty-one LARC patients performed [18F]FDG-PET/CT at baseline (PET0). All patients received continuous capecitabine concomitant to radiotherapy on the pelvis, followed by intermittent capecitabine until two weeks before curative surgery. [18F]FDG-PET/CT was also carried out at 40 Gy-time (PET1) and at the end of neoadjuvant therapy (PET2). PET imaging was analysed semi-quantitatively through the measurement of maximal standardised uptake value (SUVmax) and the tumour volume (TV). Histology was expressed through pTNM and Dworak tumor regression grading. Patients were categorised into responder (downstaging or downsizing) and non-responder (stable or progressive disease by comparison pretreatment parameters with clinical/pathological characteristics posttreatment/after surgery). Logistic regression was used to evaluate SUVmax and TV absolute and percent reduction as predictors of response rate using gender, age, and CEA as covariates. Progression-free survival (PFS) and overall survival (OS) were estimated by the Kaplan-Meier method. Survivals were compared by the Log-Rank test., Results: Twenty-three responders (9 ypCR, 14 with downstaged disease) and 18 non-responders showed differences in terms of both early and posttreatment SUVmax percent reduction (median comparison: responder = 63.2%, non-responder = 44.2%, p = 0.04 and responder = 76.9%, non-responder = 61.6%, p = 0.06 respectively). The best predictive cut-offs of treatment response for early and posttreatment SUVmax percent reduction were ≥57% and ≥66% from baseline (p = 0.02 and p = 0.01 respectively)., Conclusions: [18F]FDG-PET/CT is a reliable technique for evaluating therapy response during neoadjuvant treatment in LARC, through a categorical classification of the SUV max reduction during treatment.

Purpose: Peptide receptor radionuclide therapy (PRRT) for the treatment of neuroendocrine tumours (NET) has been explored for almost two decades, but there are still few trials that have exclusively investigated well-differentiated and moderately differentiated NET arising from the respiratory tree. Thus, the aim of this study was to explore the outcome in patients affected by bronchopulmonary carcinoid (BPC) following PRRT., Methods: We retrospectively analysed 114 patients with advanced stage BPC consecutively treated with PRRT at the European Institute of Oncology, Milan, from 1997 to 2012 and followed until October 2014. The objective responses, overall survival (OS) and progression-free survival (PFS) were rated, and three different PRRT protocols ((90)Y-DOTATOC vs. (177)Lu-DOTATATE vs. (90)Y-DOTATOC + (177)Lu-DOTATATE) were compared with regard to their efficacy and tolerability., Results: The median OS (evaluated in 94 of the 114 patients) was 58.8 months. The median PFS was 28.0 months. The (177)Lu-DOTATATE protocol resulted in the highest 5-year OS (61.4%). Morphological responses (partial responses + minor responses) were obtained in 26.5% of the cohort and were associated with longer OS and PFS. The (90)Y-DOTATOC + (177)Lu-DOTATATE protocol provided the highest response rate (38.1%). Adverse events were mild in the majority of patients. However, haematological toxicity negatively affected survival. No severe (grade 3/4) serum creatinine increase was observed. Patients treated with (90)Y-DOTATOC alone more frequently showed a mild/moderate decrease in renal function. In patients treated with chemotherapy before PRRT had a shorter OS and PFS, and a higher risk of developing nephrotoxicity., Conclusion: In a large cohort of patients with advanced BPC treated in a "real-world" scenario and followed up for a median of 45.1 months (range 2-191 months), PRRT proved to be promising in prolonging survival and delaying disease progression. Despite the potential selection biases, considering the risk-benefit ratio, (177)Lu-DOTATATE monotherapy seems the best option for PRRT. Our results indicate that the use of PRRT in earlier stages of the disease could provide a more favorable outcome.

Neurological complications of varicella-zoster virus (VZV) are infrequent and include various clinical pictures. The reactivation of VZV in patients with AIDS is generally associated with an acute and severe meningoencephalitis. We report the epidemiological, clinical and virological data from 11 consecutive patients with diagnosis of HIV/AIDS and central nervous system (CNS) involvement due to VZV. All patients were male and seropositive for HIV. The primary risk factor for HIV infection was unprotected sexual contact. The median of CD4 T cell count was 142 cells/µL. All of them presented signs and symptoms of meningoencephalitis. Six patients (54.5%) presented pleocytosis; they all showed high CSF protein concentrations with a median of 2.1 g/dL. Polymerase chain reaction of cerebrospinal fluid specimen was positive for VZV in all of them and they were treated with intravenous acyclovir at doses of 30/mg/kg/day for 21 days. Overall survival was 63% (7 of 11 patients). The four dead patients had low cellular counts in CSF, below the median of this parameter. VZV should be included among the opportunistic pathogens that can involve CNS with a diffuse and severe meningoencephalitis in patients with advanced HIV/AIDS disease.

Objective: To study the main clinical and histopathological features of 12 patients with Hodgkin's lymphoma (HL) diagnosed primarily from bone marrow (BM) involvement., Methods: We included 12 acquired immunodeficiency syndrome (AIDS) patients with HL assisted in the F. J. Muñiz Infectious Diseases Hospital since January 2002 to December 2013. The diagnosis of HL with primary BM involvement in patients was confirmed by clinical, histopathological, and immunohistochemical findings., Results: All patients presented "B" symptoms and pancytopenia. All of them had stage IV neoplasm disease because of BM infiltration. The median of CD4(+) T-cell counts was 114 cells/μL, and mixed cellularity (MC) was the most frequent histopathological subtype of 92% cases., Conclusion: When other causes are excluded, BM biopsy should be performed in AIDS patients with "B" symptoms and pancytopenia to evaluate BM infiltration by atypical lymphocytes.

Introduction Extranodal non-Hodgkin lymphomas (NHLs) are commonly described in patients with acquired immunodeficiency syndrome (AIDS) and are related with an atypical morphology and aggressive clinical course. AIDS-associated lymphomas are characterized by their rapid progression, frequent extranodal manifestations, and poor outcome. Objective The aim of this article is to remake the clinical features of head and neck (HN) NHL in patients with AIDS to facilitate early diagnosis and treatment. Methods We evaluated the epidemiologic, clinical, immunologic, virologic, and histopathologic characteristics of 24 patients with human immunodeficiency virus (HIV)/AIDS with primary HN NHL treated at a single institution between 2002 and 2012. Histopathologic diagnosis was made according to the criteria of the World Health Organization Classification of Tumors of Hematopoietic and Lymphoid Tissues. Additional immunohistochemical stains were applied in all cases. Results Eighteen patients (75%) were men and the median of age was 39 years. The gingiva and the hard palate were the most common sites of the lesions (15 patients, 62.5%). Lactate dehydrogenase levels were elevated in 16 cases (84%). Bone marrow infiltration was detected only in 4 cases (16.6%). The median CD4 T-cell count was 100 cells/µL. According to the histopathologic evaluation, the most common subtype was diffuse large B-cell lymphoma (12 cases, 50%), followed by plasmablastic lymphoma (9 cases, 37.5%) and Burkitt lymphoma (3 cases, 12.5%). Conclusion HN NHL is a severe complication of advanced HIV/AIDS disease. Early diagnosis followed by chemotherapy plus highly active antiretroviral treatment is necessary to improve the prognosis and the survival of these patients.

Introduction: Cryptococcosis is an opportunistic mycosis, especially in patients that are human immunodeficiency virus (HIV)-positive, and frequently involves the central nervous system., Methods: We assessed the potential of ventriculoperitoneal shunting (VPS) in preventing mortality due to uncontrollable intracranial hypertension (ICH) in 15 patients with acquired immunodeficiency syndrome (AIDS)-related cryptococcal meningitis., Results: After 2 weeks of antifungal therapy consisting of amphotericin B deoxycholate with or without fluconazole, patients with persistent ICH underwent VPS, despite having persistent Cryptococcus neoformans infection. In 12 patients, the uncontrollable ICH was resolved by VPS., Conclusions: Patients with cryptococcal meningoencephalitis who have ICH must be considered for VPS even with positive cerebrospinal fluid cultures.

A 42-year-old woman underwent resection of a high-risk melanoma of the right thigh. Adjuvant treatment with ipilimumab was then started within a phase III randomised, double-blind clinical trial. F-FDG PET/CT scan showed intense uptake in mediastinal hilar lymph nodes, bilaterally, and in rectus abdominis muscle. Biopsy at the abdominal wall revealed a chronic granulomatous inflammation. After oral steroid treatment, all the areas of abnormal tracer uptake disappeared. Ipilimumab can induce inflammatory immunomediated reactions that should be taken into account to avoid misinterpretation.

Background: Anal squamous cell carcinoma is a rare neoplasm with a higher incidence in the HIV-seropositive population., Patients and Methods: Epidemiologic, clinic, immunologic, virologic and therapeutic characteristics of 8 HIV-positive patients with anal squamous cell carcinoma were descriptively and retrospectively analyzed from 2005 to 2011., Results: Median of age ofpatients was 39 years, 75% were male and 83% were men who have sex with men. Median elapsed time from HIV infection to anal cancer diagnosis was 10.5 ± 9.5 years. Anal pain and local large tumors detected by physical examination were the most common clinical manifestations; pain with or without itching was marginally correlated with poor survival. The median of CD4 T-cell countfor the whole study group was 330 cells/µL. At the time ofthe neoplasm diagnosis, CD4 T-cell count was more than 200 cell/µL in 62.5% of the patients. In the descriptive analysis, higher CD4 T-cell count was significantly associated with a prolonged survival. In the overall population, 71% were receiving highly active antiretroviral therapy (HAART) and all of them had undetectable viral load at the time ofneoplasm diagnosis. HAART was correlated with better survival in the overallpopulation. Histopathologic examination showed that 4 cases (50%) had in situ carcinoma and 4 patients (50%) had diagnosis of invasive anal carcinoma. One patient underwent surgical tumorectomy plus HAART, 2 patients received chemotherapy plus HAART and 3 patients were treated with fractionated radiotherapy plus systemic chemotherapy plus HAART. One patient died without the possibility of treatment due to his poor clinical condition and for one patient was no available data. After a follow up of 2 years, overall survival rate was 71%., Conclusion: A carefully evaluation of anal infiltrative or tumoral lesions is necessary to achieve an early diagnosis and to improve the survival in this kind of patients.

A 35-year-old woman, already treated with surgery, chemotherapy, and radiotherapy for a ductal carcinoma of the left breast, underwent an (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) scan for an increase of the serum markers carcinoembryonic antigen (CEA) and cancer antigen 15.3 (CA15.3). The scan showed multiple FDG-avid lesions in the liver and bone. The images also detected two areas of uptake in the dorsal and lumbar spinal cord, which were suspicious for metastases; magnetic resonance imaging (MRI) confirmed these lesions.

Purpose: The prognostic value of FDG PET for neuroendocrine tumours (NETs) has been reported. In this study we evaluated the role of FDG PET in predicting response and progression-free survival (PFS) after (177)Lu-DOTATATE peptide receptor radionuclide therapy (Lu-PRRT) in patients with advanced well-differentiated grade 1/2 NETs., Methods: We retrospectively evaluated 52 patients with progressive advanced NETs overexpressing somatostatin receptors and treated with Lu-PRRT with a cumulative activity up to 27.7 GBq divided into five courses. According to WHO 2010/ENETS classification, patients were stratified into two groups: those with grade 1 tumour (Ki-67 index ≤2 %, 19 patients), and those with grade 2 tumour (Ki-67 index >3 % to <20 %, 33 patients). On the basis of the FDG PET scan, 33 patients were classified as PET-positive (PET+) and 19 as PET-negative (PET-)., Results: FDG PET was positive in 57 % of patients with grade 1 NET and in 66 % of patients with grade 2 NET, and the rates of disease control (DC, i.e. complete response + partial response + stable disease) in grade 1 and grade 2 patients were 95 % and 79 %, respectively (P = 0.232). In PET- and PET+ patients, the DC rates were 100 % and 76 % (P = 0.020) with a PFS of 32 and 20 months, respectively (P = 0.033). Of the PET+ patients with grade 1 NET, 91 % showed disease control, whereas about one in three PET+ patients with grade 2 NET (32 %) progressed after Lu-PRRT (DC rate 68 %)., Conclusion: These results suggest that FDG PET evaluation is useful for predicting response to Lu-PRRT in patients with grade 1/2 advanced NETs. Notably, none of PET- patients had progressed at the first follow-up examination after Lu-PRRT. Grade 2 NET and PET+ (arbitrary SUV cutoff >2.5) were frequently associated with more aggressive disease. PET+ patients with grade 2 NET, 32 % of whom did not respond to Lu-PRRT monotherapy, might benefit from more intensive therapy protocols, such as the combination of chemotherapy and PRRT.

Background: We retrospectively investigated (18)F-FDG uptake by the primary breast tumor as a predictor for relapse and survival., Patients and Methods: We studied 203 patients with cT1-T3N0 breast cancer. Standardized uptake value (SUVmax), was measured on the primary tumor. After a median follow-up of 68 months (range 22-80), the relation between SUVmax and tumor factors, disease free-survival (DFS) and overall survival (OS) was investigated., Results: In the PET-positive patients, the median FDG uptake by the tumor was 4.7. FDG uptake was significantly related to tumor size, number of involved axillary nodes, grade, negative ER, high Ki-67 and HER2 overexpression. No distant metastases or deaths occurred in the PET-negative group. Five-year DFS was 97% and 83%, respectively in the PET-negative and PET-positive groups (P = 0.096). At univariate analysis, DFS was significantly lower in patients with SUVmax >4.7 compared to the patients with negative PET (P = 0.042), but not to the patients with SUVmax ≤4.7 (P = 0.106). At multivariable analysis, among PET-positive patients, SUVmax was not an independent prognostic factor for DFS (HR(>4.7 vs ≤4.7): 1.02 (95% CI 0.45-2.31)). Five-year OS was 100% and 93%, respectively, in the PET-negative and PET-positive groups (P = 0.126)., Conclusion: FDG uptake by the primary lesion was significantly associated with several prognostic variables, but it was not an independent prognostic factor., (Copyright © 2012 Elsevier Ltd.

MATline, the job-exposure matrix for carcinogenic agents, is a data bank free accessible online. It provides data as classification and toxicological properties of carcinogenic agents, and a list of industrial processes with potential exposure to each carcinogen agent, and an up-to-date estimation of the number of activities and workers related to the industrial process on Regional basis. It also lists the target organs for which a causal relationship with the agent has been established. MATline was recently updated with the new classifications introduced by Regulation EC No. 1272/2008 (CLP). The Authorisation List or the Restriction of the Registration, Evaluation, Authorization of Chemicals (REACh) regulation specifically mark chemicals. The matrix is helpful for professionals in the public health sector to identify in advance the potential sources of exposure, and prioritise intervention plans; for occupational physicians to help identifying causes of occupational cancer cases; for health professionals in the private sector to address chemical risks; for company physicians to validate health surveillance plans; for trade unions to independently check formation contents provided to workers potentially exposed to such risks.
