Infection in limb salvage surgery for bone tumors

The authors present a retrospective study of 66 infected cases in their series of limb salvage surgery performed from January 84 to August 92. Special emphasis was given to the alternative techniques of treatment in infection. In 85% of the cases healing was achieved, however removal of the implant and amputation are still frequent occurrences. Time to recovery is very demanding.     

Isolated resection of segment 8 for liver tumors: a new approach for anatomical segmentectomy

HYPOTHESIS: Isolated resection of segment 8 (the right anterosuperior liver segment) is one of the most difficult hepatectomies to perform because of the location of segment 8, the relation between section 8 and the main intrahepatic vessels, and the absence of any anatomical landmarks. The few reports that deal with isolated resection of section 8 generally describe the use of a deep wedge transparenchymal transection. DESIGN: Original surgical technique. PATIENTS AND METHODS: The proposed technique is based on the extraparenchymal isolation and temporary clamping of the right anterior artery and portal branches, causing ischemic demarcation on the liver surface, which corresponds to the anatomical borders of the right paramedian segments (5 and 8). The liver is widely transected along the main hepatic fissure; then the pedicles of segment 8 are selectively ligated inside the parenchyma, and the resection is accomplished. This technique was used in 10 patients: 5 with hepatocellular carcinoma on cirrhosis and 5 with liver metastases. RESULTS: The mean operation time was 253 minutes. Intraoperative blood loss was minimal in all cases, and 7 patients did not require blood transfusion. Slight complications developed in 3 patients, and there was no operative death. The mean hospital stay was 9.3 days. CONCLUSIONS: This operative procedure is safe and ensures a complete anatomical resection of segment 8. The wide opening of the liver parenchyma facilitates hemostasis and makes it possible to obtain a correct resection margin. This technique is recommended for limited metastatic lesions located in segment 8 or for hepatocellular carcinoma arising in a cirrhotic liver.     

Fetal variant of circle of the Willis and bilateral symmetrical parietal stroke

We described a rare case in which a congenital abnormal vascular structure associated with mild hyperhomocysteinemia could have caused an ischemic stroke, with an unusual localization in the border-zone of MCA and PCA. We think that the lack of compensatory flow distribution from the right vertebral artery and the right posterior communicating artery probably determined the bilateral ischemic lesions in a patient, who possibly had hypotensive crisis.     

2D shear wave elastography in evaluation of prognostic factors in breast cancer

Purpose

To evaluate the reproducibility of the 2D shear wave elastography (2D-SWE) method and to identify the prognostic factors of breast lesions.

Methods

In this prospective study, 44 female patients were consecutively included from January 2020 to September 2021. All patients showing visible masses at B-mode ultrasound underwent to clinical evaluation, followed by qualitative and quantitative 2D-SWE by two different operators with over 15-year and 2-year experience, respectively. Subsequently, patients underwent to surgical treatment after core needle biopsy. Reproducibility of qualitative and quantitative 2D-SWE was evaluated by Cohen’s kappa and intraclass correlation coefficient (ICC). Clinical, imaging, and histopathological data and 2D-SWE evaluations were analysed with Spearman's rank correlation test.

Results

The mean age of the patients was 55 years?±?12. The mean histological and ultrasound tumour size of were 23.1 mm?±?13.2 and 17.2 mm?±?10.2, respectively. The interobserver agreement showed a good reproducibility limited to the qualitative evaluation colour maps (Cohen’s kappa?=?0.603) and to the quantitative evaluation E ratio (ICC?=?0.771). Correlation analysis between the ultrasound and 2D-SWE values and the clinical-pathological parameters showed a significant relationship between E ratio and Elston–Ellis grading (P?<?0.030) and between tumour size and Elston–Ellis grading (P?<?0.041).

Conclusion

The 2D-SWE has shown good reproducibility among operators with different experience. It could be a promising tool in the evaluation of some prognostic factors in ultrasound visible breast cancer.

     

Caring Advanced Cancer Patients at Home During COVID-19 Outbreak: Burnout and Psychological Morbidity Among Palliative Care Professionals in Italy

ContextProviding palliative care (PC) at home for patients with advanced cancer has become essential during the COVID-19 emergency. Nevertheless, the home PC professionals (PCPs) faced a challenging situation because of increased number of discharged patients, reduced availability of health-care facilities, and physical/relational barriers between them and patients.ObjectivesThis study aimed to investigate the impact of COVID-19 pandemic on burnout and psychological morbidity among home PCPs in Italy.MethodsOne hundred and ninety-eight PC physicians and nurses working in home assistance in Italy were invited to participate. The results obtained by the investigation conducted during the COVID-19 emergency (COVID2020) were compared with data collected in 2016 in the same setting (BURNOUT2016). The questionnaires (socio-demographics, Maslach Burnout Inventory and General Health Questionnaire-12) were the same for both the surveys. The PCPs participating in COVID2020 survey (n = 145) were mostly the same (70%) who participated in the BURNOUT2016 study (n = 179).ResultsOne hundred and forty-five PCPs participated in the study (response rate 73.2%). During the COVID-19 emergency, home PCPs presented a lower burnout frequency (P < .001) and higher level of personal accomplishment than in 2016 (P = .047). Conversely, the risk for psychological morbidity was significantly higher during the pandemic (P < .001).ConclusionsIn the age of COVID-19, the awareness of being at the forefront of containing the pandemic along with the sense of responsibility toward their high-risk patients may arouse PCPs' psychological distress, but, on the other hand, this condition may improve their sense of professional satisfaction and personal accomplishment.     

What is the probability of being too old for salvage transplantation after hepatocellular carcinoma resection?

BackgroundThe strategy of salvage transplantation for patients with hepatocellular carcinoma is based on the premise that tumour recurrence will be still transplantable at the time of recurrence. However, patients can not only present non-transplantable recurrence but can also be over the age limit accepted for transplantation.AimsTo measure the risk of being too old for salvage transplantation of patients resected for hepatocellular carcinoma within Milan criteria.MethodsA Markov simulation model was developed on the basis of published literature.ResultsThe risk of being too old for salvage transplantation depends on the time-span between age at hepatic resection and age limit, and the expected median waiting-time. Patients resected at an age 2 or 3 years below the age limit carry a risk of being too old that overcomes the probability of receiving transplantation. Salvage strategy can cause harm that depends on the tumour characteristics and degree of portal hypertension, becoming maximal for patients with multiple tumours, clinical signs of portal hypertension and increased bilirubin levels.ConclusionsThe best strategy to adopt should be balanced between the risk of being too old and the expected transplant benefit, but salvage strategy could be pursued if it did not turn into significant harm in comparison to primary transplantation.     

Liver Transplantation for Recurrent Hepatocellular Carcinoma on Cirrhosis After Liver Resection: University of Bologna Experience

Liver resection (LR) for patients with small hepatocellular carcinoma (HCC) with preserved liver function, employing liver transplantation (LT) as a salvage procedure (SLT) in the event of HCC recurrence, is a debated strategy.
From 1996 to 2005, we treated 227 cirrhotic patients with HCC transplantable: 80 LRs and 147 LTs of 293 listed for transplantation. Among 80 patients eligible for transplantation who underwent LR, 39 (49%) developed HCC recurrence and 12/39 (31%) of these patients presented HCC recurrence outside Milan criteria. Only 10 of the 39 patients underwent LT, a transplantation rate of 26% of patients with HCC recurrence.
According to intention-to-treat analysis of transplantable HCC patients who underwent LR (n = 80), compared to all those listed for transplantation (n = 293), 5-year overall survival was 66% in the LR group versus 58% in patients listed for LT, respectively (p = NS); 5-year disease-free survival was 41% in the LR group versus 54% in patients listed for LT (p = NS).
Comparable 5-year overall (62% vs. 73%, p = NS) and disease-free (48% vs. 71%, p = NS) survival rates were obtained for SLT and primary LT for HCC, respectively.
LR is a valid treatment for small HCC and in the event of recurrence, SLT is a safe and effective procedure.
