Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

[Management of facial pain resulting from cancer in oral and maxillofacial surgery]. Il trattamento del dolore facciale di natura oncologica in chirurgia oro-maxillo-facciale.

Pain, which is among the most prevalent symptoms experienced by cancer patients, must absolutely be treated. The most important biologic effects of this sort of pain plays on patients' psychosociality. This is in reference to the quality of pain, the amount of pain and to the character of the patients. Actually, pain only in appearance is presented as a symptom; it is usually a disease. Patient assessment, the use of anticancer therapies and systematically administered non-opioid and opioid analgesics are pivotal. Practical aspects of cancer pain treatment include both drug selection, method of analgesic administration: selection of the appropriate route, dose titration and an understanding of the management of side effects. Pain therapy includes another series of possibilities like the use of adjuvant analgesics, psychological therapies, physiatric techniques and invasive interventions such as the use of intraspinal drugs, neural blockade and neuroablative techniques. This kind of therapy must be employed at all times, whether the case may be resolved surgically or not. So we think that pain can be effectively treated. This study was carried out to obtain the correct therapeutic approach for facial cancer pain syndrome. The research was performed on seven women and thirteen men with a mean age of 58 years. All the patients' clinical appearances were standardized with care. Study participants included odontostomatologists and anesthesiologists with experience of controlling cancer pain. The sensation of pain was quantified by means of the Visual Analogue Scale (VAS) while their psychosocial ability was assessed with the Karnofsky Performance Scale (KPS). In this way the authors hoped to obtain a good quality of standardization. The study was performed for a period of two months. The conclusions are that Trans Epidermis Nervous Stimulation (TENS) offers positive results for variable periods and only in 60% of patients with a low level of pain. The use of antiphlogistic non-steroid drugs and of opioid drugs, with a particular management requested from the personal clinical status of each patient, result as being the most effective therapeutic resource. Such therapies must be employed, whether the case may be resolved surgically or not. Nevertheless it is necessary to realize that drugs or other therapies for cancer pain are independent and propaedeutic to each surgical approach. Finally, the use of opioids is addressed in the management of patients with pain that is refractory to other interventions. This approach can provide adequate relief to the vast majority of patients. We find the morphinomania risk in cancer pain patients is not scientifically wellfounded. PMID: 917321

Primary osteosarcoma of the kidney with retroperitoneal hemorrhage. Case report and review of the literature.

Primary osteosarcoma of the kidney is a very rare neoplasm with a very poor prognosis and unclear histogenesis. Only 20 cases have been reported in the literature. It has a strong tendency to recur locally and spread to distant sites.We present the clinical case of a 79-year-old man affected by a primary osteosarcoma of the kidney presenting with substantial retroperitoneal tumor hemorrhage. Laparotomy revealed a massive retroperitoneal hematoma due to a bleeding large stony renal mass with multiple bizarre calcifications. The diagnosis of primary renal osteosarcoma was made on the basis of hematoxylin-eosin staining and confirmed by electron microscopy. Hematoma drainage and radical nephrectomy were performed. To our knowledge this is the first case of bleeding renal osteosarcoma reported in the literature. The most important clinical findings, the pathogenesis and the treatment modalities of this rare neoplasm are discussed

Traditional and new prognosticators in breast cancer. Nottingham index, Mib-1 and estrogen receptor signaling relmain the best predictors of relapse and survival in a series of 289 cases.

7Histopathological and immunohistochemical findings on tissue microarrays, overall survival (OS), disease-free survival (DFS) and incidence of relapses (R) were recorded and statistically analyzed in 289 breast cancers. A higher R and a shorter DFS were significantly related to larger tumors, lymph node invasion, higher tumor grade, absence of estrogen receptors (ER), triple negative tumors, and presence of lymphovascular invasion (LVI). Longer OS was observed to be significantly associated with smaller tumor size (T), lymph node negativity, lower tumor grade, absence of LVI, lower Mib-1 expression and with the presence of ER. At multivariate analysis, only T for DFS and lymph node status and triple negativity either for DFS or OS had independent prognostic value. In the 194 lymph node-negative women DFS and OS were inversely related to tumor grade, absence of ER, Mib-1 expression in more than 15% of neoplastic cells and, only for DFS, presence of LVI. In the 95 lymph node-positive the number of involved nodes was the most discriminating parameter either for DFS or OS; T, Her-2 status and presence of LVI were significantly related to DFS. ER negativity was related to higher grade, progesterone receptors (PR) negativity, Her-2 negativity, hence to triple negativity, to basal-like type, Mib-1expression over 15% of neoplastic cells. Her-2 positivity was related to higher grade, ER positivity and PR positivity. Basal-like type was not an independent prognosticator, while triple negative type has a significant relation to shorter OS. The Nottingham prognostic index accurately identifies prognostic groupings and Mib-1 expression and ER signaling are the key biological predictors even in single cases.reservedmixedMEGHA T; NERI A; MALAGNINO V; CARUSO S; ONORATI M; F.

Standard conditioning regimen and T-depleted donor bone marrow for transplantation in chronic myeloid leukemia

Between January 1984 to June 1985, 18 Ph1 positive chronic myeloid leukemia (CML) patients in chronic phase (CP) underwent allogeneic bone marrow transplantation (BMT) from HLA identical and MLC negative siblings. The median age was 32.5 yr and median disease duration of CML at time of BMT was 19.3 months. The pretransplant conditioning regimen consisted of cyclophosphamide (CTX) (120 mg/kg) and 10.20 Gy total body irradiation (TBI) at 6 doses of 1.7 Gy each, administered in 3 daily fractions over 2 days at a dose rate of 15-20 cGy/min. To prevent graft-vs-host disease (GvHD) we used methotrexate (MTX) in one patient and cyclosporin-A (CYA) in the other 17 patients. In addition to CYA, given until day +365, 10 patients received donor marrow depleted of T cells with CAMPATH-1. The residual marrow lymphocytes were always less than 1%. The rate of engraftment was significantly correlated with the number of nucleated cells infused. Neither GvHD nor graft failure were observed among CAMPATH-1 patients. In this group one cytogenetic and one hematologic relapse occurred. The overall actuarial survival at 24 months is 78%. Of the 10 patients treated with donor marrow depleted of T cells, 9 are alive after a median follow-up of 9 months (range 5-18), with an actuarial survival of 90%. Of the other 8 patients transplanted with untreated marrow, 5 are alive after a median follow-up of 19.3 months (range 3.7-24) and the actuarial survival is 63.8%. This pilot study seems to demonstrate that T-cell depletion of donor bone marrow with CAMPATH-1 is effective to prevent GvHD, while the risk of graft failure can be avoided using a "standard" conditioning regimen including a fractionated TBI with a fast dose rate and a prolonged administration of CYA at the maximum tolerable dosage. While the high frequency of relapses suggests the employ of more aggressive anti-leukemic conditioning regimens in CAMPATH-1 treated marrow recipients

Langerhans' cell histiocytosis in adults - A clinical and therapeutic analysis of 11 patients from a single institution

BACKGROUND. Langerhans' cell histiocytosis (LCH) is a rare disorder of uncertain etiology, characterized by a wide clinical spectrum and varied behavior. METHODS. This retrospective study analyzed 11 adult patients with a diagnosis of LCH observed at the study institution between April 1988 and March 1993. RESULTS. Based on the sites and extent of disease at diagnosis, patients were divided into four categories. Group A was comprised of four patients with unifocal bone disease who had surgical curettage. At last follow-up only 1 patient was in continuous complete response (CCR) at 29+ months. The other 3 patients recurred at 3, 12, and 30 months, respectively, after surgery and at last follow-up were found to be in CR at 16+, 48+, and 124+ months, respectively, after therapy with vinblastine (VBL) and high dose methylprednisolone (HDMP). Group B was comprised of three patients with multifocal bone disease. Two of these patients received VBL + HDMP; at last follow-up, 1 patient tvas in CCR 8 months after completion of therapy, and the other developed progressive disease 11 months later. The third patient was treated with interferon (IFN) and at last follow-up was in CCR at 35+ months. Group C was comprised of 2 patients with bone and visceral disease who were treated with etoposide (VP-16) + HDMP; at last follow-up, 1 patient was in CCR at 42+ months and the other patient, who had isolated vulvar recurrence 16 months later, was in CR with treatment with local IFN. Group D was comprised of two patients with lung and lymph node involvement, one of whom was treated with VP-16 + HDMP and the other with cyclophosphamide, doxorubicin, vincristine, and prednisone; at last follow-up, both were in CCR at 30+ and 71+ months, respectively. CONCLUSIONS. VBL + HDMP showed efficacy in patients with bone disease, in particular those treated for recurrent LCH after surgery. Therapy with VP-16 and HDMP was successfully employed in patients with visceral disease. IFN was effective both for localized disease and in patients with multiple bone lesions.

Tuberculosis-Related Hospitalizations in a Low-Incidence Country: A Retrospective Analysis in Two Italian Infectious Diseases Wards

In recent years, a decrease in the incidence of tuberculosis (TB) has been recorded worldwide. However, an increase in TB cases has been reported in foreign people living in low-incidence countries, with an increase in extrapulmonary TB (EPTB) in the western region of the world. In the present work, a retrospective study was conducted in two Italian infectious diseases wards to evaluate the clinical characteristics of TB admission in the time period 2013–2017. A significant increase in TB was shown in the study period: 166 (71% males) patients with TB were enrolled, with ~70% coming from outside Italy (30% from Africa, 25% from Europe, and 13% from Asia and South America). Compared to foreign people, Italians were significantly older (71.5 (interquartile range, IQR: 44.5–80.0) vs. 30 (IQR: 24–40) years; p < 0.0001) more immunocompromised (48% vs. 17%; p < 0.0001), and affected by comorbidities (44% vs. 14%; p < 0.0001). EPTB represented 37% of all forms of the disease, and it was more incident in subjects coming from Africa than in those coming from Europe (39.3% vs. 20%, respectively). In logistic regression analysis, being European was protective (odd ratio, OR (95% CI): 0.2 (0.1–0.6); p = 0.004) against the development of EPTB forms. In conclusion, an increase in the rate of TB diagnosis was documented in two Italian reference centers in the period 2013–2017, with 39% of EPTB diagnosed in patients from outside Europe
