ABSTRACT
Abstract: Despite the advances made by therapeutic technologies, healthcare-associated infections (HAIs) are currently still a worldwide problem. Central-line-associated bloodstream infections (CLABSIs) are one of the most common causes of HAIs. The cost of CLABSIs is considerable, both for the increase in morbidity and financial resources expenses. Coagulase-negative staphylococci are the common pathogens responsible for CLABSIs, followed by Staphylococcus aureus, Enterococci, and Candida spp. The Enterococcus genus comprises of more than 50 species but E. faecalis and E. faecium are the most common causes of infections in humans. Enterococcus Raffinosus (ER) is a non-faecalis and non-faecium enterococcus even if ER has rarely been proven to be a human pathogen, recent reports of infections caused by enterococci that are relatively resistant to beta-lactam antibiotics by non-p-lactamase mechanisms have included strains of ER. Here we describe a first report of CLABSI due to Enterococcus Raffinosus in a cancer patient.

Introduction: Multiple chemical sensitivity (MCS), is a syndrome characterised by increased sensitivity to the exposure of environmental chemicals (1). There are considerable difficulties in reaching a good estimate of the prevalence of disease and the main pathogenetic hypotheses take into account both the organic and psychiatric/psychological factors. Treatment with epidermal growth factor tyrosine kinase receptor inhibitors (tkis), like Osimertinib, results in improved progression-free survival (PFS) compared to chemotherapy, in Non-small-cell lung carcinoma (NSCLC) with epidermal growth factor receptor (EGFR) mutation (2). Case report: We describe the case of a 74 year old woman with history of MCS and fibromyalgia in treatment with Osimertinib for EGFR-mutated NSCLC. Patient initially refused any form of active therapy for lung cancer, but thanks to teamwork and the important support of the psychologist, the patient decided to start treatment with Osimertinib at a reduced dose, not 80 mg but 40 mg. Subsequently, after few days , of his own free will and without informing the staff physicians, the patient changed the treatment schedule by taking one quarter of the dose of the medicine every other day, justifying this choice in therapeutic modification because of her fear and intolerance to any type of medicine and/ or chemical substance, being influenced by MCS. Management & outcome: Despite the changes in the treatment plan, a PET scan performed after two months showed a sigificative lung response and the stability of bone metastases. Discussion. Our case describes a significative response with Osimertinib despite the change in dosage and schedule in a patient with MCS. Our experience deserves to be considered in the light of its particularity and uniqueness as it shows an excellent response to treatment with Osimertinib despite the change made to the dosage and schedule, in a patient presenting in her medical history this rare pathological condition: MCS syndrome.

Background: Breast is a symbol of femininity, motherhood and sexuality. Breast cancer (BC) is the leading cause of cancer death in women worldwide and most frequent cancer in Italy: in 2019, 53.500 new cases were diagnosed. BC and its treatment, the disturbances of body image, and mental health problems such as anxiety and depression could influence sexuality. Very often the aspect of sexuality in BC is likely not to be fully investigated: cultural barriers may also contribute to lack of attention to these issues. In Italy, there are very few Breast Units that provide the figure of the sexologist and psycho-oncologist. Methods: We enlisted 141 BC patients (pts), mean age was 54 years afferent to Breast Unit S. Maria Goretti Hospital, Latina, from March 2019 to March 2020. All pts had undergone surgical intervention. Participants were invited to complete a structured questionnaire, which included four close-up questions regarding self-image, sexual activity, sexual satisfaction, analyzing these aspects before and after BC and its treatments. Finally the participants were asked if they needed the sexologist and psycho-oncologist. Results: Only 2/141 pts (1.41%) refused to participate in our study. Of 139 participants, 68 (48.92%) had disturbances of body image, 26 (18.7%) had sexuality greatly negatively affected, and 103 (74.1%) every kind of sexual dissatisfaction after BC. 38 pts (27.3%) would require the help of the sexologist. 135 ( 97%) would require the help of the psycho-oncologist. Despite the negative influence in their body-image and sexuality, few pts require the help of the sexologist, but nearly all pts require the help of the psycho-oncologist. Conclusion: In our study nearly all pts require the help of the psycho-oncologist, but few pts of the sexologist. Further studies will be needed to understand the reasons for this disparity: at the moment we are carrying out another project following this illustration, with the aim of understanding why this disparity.

ABSTRACT: Nasopharyngeal carcinoma, one of the most common head and neck cancers in Southeast Asia, is uncommon in Western countries and it is frequently diagnosed in advanced stage. Chemotherapy given with radiation therapy, followed by more chemotherapy, is the standard of care of stage IV nasopharyngeal carcinoma but Cetuximab, an epidermal growth factor (EGFR) inhibitor, is now making its way in the treatment of locoregionally advanced nasopharyngeal carcinoma. We report a case of 58 years old patient with metastatic nasopharyngeal carcinoma with an astonishing response to Cetuximab. At the time of writing, the patient is still in treatment with Cetuximab with excellent disease control.

SUMMARY: The reduction of ovarian function and a decrease in estrogen levels marked by menopause are related to increased susceptibility to develop dyslipidemia. These alterations in the lipid profile can have consequences in renal tissue and generate injuries that may progress to renal failure. The practice of physical activity is an important factor for the treatment and prevention of dyslipidemia and its consequences. The objective of this study is to observe the effects of physical exercise on the right kidney of ovariectomized female LDL knockout mice. Animals were submitted to moderate physical exercise, sacrificed, and the right kidney was removed for morphometric and stereological analysis. The results showed that dyslipidemia promoted a decrease in the areas of the corpuscle and renal glomerulus, in the volume density of light in both the proximal and distal convoluted tubules, and an increase in capsular space, particularly more marked in the proximal tubules. We also observed that physical exercise decreased the analyzed parameters. Our results suggest the association of physical training and dyslipidemia presents a tendency to reduce the dimensions of morphometric and stereological parameters of the kidney. These changes may be related to metabolic and physiological adaptation of renal tissue during physical exercise.
RESUMEN: La reducción de la función ovárica y una disminución en los niveles de estrógeno, marcados por la menopausia, se relacionan con una mayor susceptibilidad a desarrollar dislipidemia. Estas alteraciones en el perfil lipídico pueden tener consecuencias en el tejido renal y generar lesiones que pueden progresar a insuficiencia renal. La práctica de la actividad física es un factor importante para el tratamiento y la prevención de la dislipidemia y sus consecuencias. El objetivo de este estudio fue observar los efectos del ejercicio físico en el riñón derecho de ratones hembras con LDL ovariectomizados. Los animales fueron sometidos a ejercicio físico moderado, se sacrificaron y se extrajo el riñón derecho para el análisis morfométrico y estereológico. Los resultados mostraron que la dislipidemia promovió una disminución en las áreas del corpúsculo y el glomérulo renal, en la densidad volumétrica de la luz en los túbulos contorneados proximales y distales, y un aumento en el espacio capsular, particularmente más marcado en los túbulos proximales. También observamos que el ejercicio físico disminuyó los parámetros analizados. Nuestros resultados sugieren que la asociación del entrenamiento físico y la dislipidemia presentan una tendencia a reducir las dimensiones de los parámetros morfométricos y estereológicos del riñón. Estos cambios pueden estar relacionados con la adaptación metabólica y fisiológica del tejido renal durante el ejercicio físico.

BACKGROUND: Angiosarcoma (AS) is a rare and malignant tumor which mainly arises in the skin and superficial soft tissue and less frequently in deep soft tissue and bones. Some cases of AS are described in association with vascular and orthopedic devices. Nonetheless, only a few cases of AS around THA are reported in the literature. MATERIALS AND METHODS: We describe five cases of AS arising around total hip arthroplasty who received surgery at our institution (Istituto Ortopedico Rizzoli, Bologna, Italy), and we report the cases described in literature. RESULTS: Foreign bodies such as polyethylene were demonstrated to have a carcinogenic role in animals, but reports of similar cases in humans are rare. Nevertheless, osteolysis induced by wear particles of polyethylene is a frequent event and could induce to desist form considering other more rare causes of osteolysis such as AS. This could be the reason why the diagnosis in several cases was significantly delayed. Common features of these cases could be helpful for doing a prompt diagnosis. The initial presentation is suggestive for septic or aseptic loosening with a massive osteolysis around the cup and/or the stem associated with peculiar aspects as bleeding and loss of weight. Frequently, needle biopsy is negative because foreign-body reaction might have "covered" the most relevant condition of epithelioid AS. CONCLUSIONS: In conclusion in a patient who presents with uncontrollable bleeding, loss of weight and massive osteolysis, AS must be actually considered as possible diagnosis.

Total knee modular megaprosthesis or osteochondral allograft are used to preserve joint movement in bone tumours of the proximal tibia. The aim of this study was to compare two groups of patients with total knee modular megaprosthesis and osteochondral allograft through an objective analysis. Eighteen patients, ten treated with prosthesis (TKR group) and eight with osteochondral allografts (AL group), were included in the study. X-ray, muscular strength measurements, and studies of gait analysis including electromyography (EMG) were used to compare functional results of patients. In the TKR group a higher incidence of knee extension lag was found. While the TKR group had a prevalent knee stiff/hyperextension pattern with reduced rectus femoris activity, the AL group had a higher percentage of normal knee pattern. Knee extensor muscular strength was reduced in the TKR group. TKR functional performance during gait is in most cases abnormal, consistent with the weakness of the extensor apparatus and knee extension lag. Although a greater rate of normal walking was found in the AL group, problems related to a short patellar tendon, knee instability, and joint mismatching were considered to be responsible for abnormal knee kinematics. An allograft, when optimal reconstruction is performed, gives better functional results.

Bone grafting procedures are widely used to repair large defects successfully in humans, but new surgical therapies can be designed to improve allograft integration. The objective of this study was to investigate the best surgical procedure to study bone graft integration in a large animal model. An osteoperiosteal defect of 3 cm in the tibia or in the metatarsal was made in 15 adult crossbreed sheep to investigate osteo-integration of a homologous bone graft in an intercalary critical defect. DCP plates, alone or in association with Scotchcast or external fixator were used as fixation devices. The Scotchcast as was applied after surgery and left for 2 months to avoid torsion stress of the limb during the stand up movement. Metatarsal defect fixed with 7-hole DCP plate and protected with Scotchcast was the best surgical approach to avoid early or late implant failures, and provided good radiographic results after 4 months.

AIMS: To describe the outcomes of a large number of patients with pelvic osteosarcoma, and to define the guidelines for appropriate treatment. METHODS: We reviewed 60 consecutive patients with primary pelvic high-grade osteosarcoma. The tumour involved the whole hemipelvis in 15 cases, while the most common location was the iliac wing in 29 cases (48.3%): 25 of these adjacent to or passing the sacroiliac joint. RESULTS: Thirty patients underwent surgery; there were 16 hindquarter amputations and 14 internal hemipelvectomies. All the patients who presented with metastasis died of their disease. In 18 cases wide margins were achieved, however, eight patients experienced local recurrence. Of the series, only eight patients are still alive. CONCLUSION: The use of intense chemotherapy and surgical wide margin, hardly seems to achieve local control, however, tumour necrosis was correlated with positive prognosis. When internal hemipelvectomy it is not safe enough, amputation must be considered, particularly for cases with sacrifice of the sciatic nerve roots or for older patients where a shorter surgical procedure can be less risky.

Osteosarcoma is a rare tumor. In multicentric trials on the neoadjuvant treatment of this neoplasm many of the single institutions involved have the opportunity to treat a small number of cases (the average for all of the studies was less than 1 case per year). In order to verify whether this can change the percentage of amputations avoided and prognosis, a review of the current literature was carried out, concerning neoadjuvant treatment of osteosarcoma of the extremities. The results obtained in 9 multicentric trials and in 12 mono-institutional trials were evaluated. It was observed that in mono-institutional studies the percentage of patients treated by conservative surgery instead of aggressive surgery (73% vs 55%) and the disease-free survival 5 years after surgery (73% vs 55%; p < 0.0001) are significantly higher as compared to what was observed for patients treated in multicentric trials. Based on these differences, the authors conclude that it would be opportune to direct patients with osteosarcoma of the extremities to the best centers that each year treat large numbers of patients with musculoskeletal tumors.

The need for a better roentgenographic evaluation of implant behavior in long-term prosthetic replacement of the proximal femur was considered. The authors present the results of a group of 13 patients belonging to a wide range of ages, with more than ten-years follow-up after tumor resection, and replacement characterized by bipolar cup and non-cemented stem. A new X-ray film acquisition and evaluation method was devised. Results confirmed the good behavior of bipolar reconstructions in patients of different ages, whose sockets were still intact. In younger patients, the prevalent bipolar movement was in the outer bearing, thus limiting polyethylene particulate debris formation. However, debris formation did not significantly affect the bone/stem relationship as only one loose stem was observed in a bone submitted to radiotherapy.

We reviewed our experience as concerns 588 patients treated by resection for bone tumor and reconstructed by massive bank bone implant. The period taken into consideration goes from 1984 to 2001. The mean age of the patients was 24 years with a minimum of 1 and a maximum of 77 years: in 186 cases (31.6%) age was lower by 14 years. Most of the patients were referred for a diagnosis of malignancy (85%), and of these, 70% had undergone antiblastic therapy postoperatively according to the modalities of the protocols. Of the cases that were not treated by chemotherapy there are 16 that had a homoplastic graft after failure of a previous one. In a high number of cases (189) surgery included reconstruction of an intercalar segment of a long bone. Of these, 106 were in the femur, 69 in the tibia, and 14 in the humerus. One joint reconstruction was carried out in 128 cases of which 52 in the knee, 49 in the shoulder, 10 in the elbow, 11 in the wrist, 3 in the ankle, and 3 in the metatarsals. Fusion, which was one of the most frequent indications in the eighties, is used less today; overall it was carried out in 91 cases of which 65 in the knee, 14 in the hip, 9 in the ankle and 3 in the wrist. This type of implant may also be used in the pelves, and this took place in 56 cases using different procedures of reconstruction. The most current method of reconstruction for a joint is composite prosthesis, and this was used in 124 cases of which 67 around a knee, 53 in the hip, 4 in the shoulder. Finally, in 78 cases a vascularized fibula transplant was associated with an intercalar graft, fusion, or osteoarticular graft to increase the mechanical capacity of the implant together with a more rapid integration of the implant, particularly at the osteotomic lines. Despite the excellent results demonstrated in the first 3 years of follow-up, infection, resorption, delay in consolidation and fracture led to 18% failures of the implant. Massive homoplastic graft is still a good means of reconstruction that allows for excellent functional results, but despite this intense research activity is required to improve its mechanical hold in time together with better and complete integration.

A consecutive series of 57 patients treated by knee resection arthrodesis for malignant or aggressive tumor around the knee was reviewed. Infection was present only after repeated surgery for other complications, delayed union or non-union occurred in 50% of the cases that could be evaluated, but were still easy to manage. Fracture incidence was higher than expected (32.6%) even occurring after 10 years; this was difficult to deal with and it often led to failure. The best possible method of fixation is still being debated, but locked nail and allograft cementation is often advised. Several satisfactory functional results were however achieved when surgery was performed in young patients; final results can be less satisfactory when there is leg length discrepancy and poor acceptance on the part of the patient. In recent years this type of surgery has been limited to younger male patients (10 to 14 years of age) in whom extra-articular knee resection was required or when most of the quadriceps muscle must be removed.

The current study consists of an outcome review of a consecutive series of 92 patients with knee arthrodesis using an allograft, done for malignant or aggressive tumors in two centers on different continents during a period of 18 years (mean followup, 5 +/- 4 years). The data were compiled by creating a computerized file using the information provided by both centers. Seventy-five of the patients (81%) had high-grade nonmetastatic tumors (Stage II), mostly osteosarcoma. In addition seven (8%) had metastases at outset (Stage III) and the remaining 10 (11%) had benign disease, mostly giant cell tumor or revision procedures for failed allograft or total joint replacement. Seventy-two patients (78%) had distal femoral lesions (78%) whereas the proximal tibia was the site of the tumor in 20 patients (22%). The average age of the patients was 23 +/- 16 years; 51 were males and 41 were females. Tumor complications were a major problem for patients in the series. Thirty-four percent of the patients died, 47% had metastases develop, and 9% had a local recurrence. Allograft complications included an infection rate of 20%, a fracture rate of 25%, and a nonunion rate of 44%. Repeat surgery was required for more than 50% of the patients with 26 requiring one additional operation, 11 requiring two, and 10 requiring three or more operations. Nineteen of the patients required an amputation (20%), only four of which were for recurrent tumor. When these data were compared with data for a control series of 880 patients with allografts other than allograft arthrodeses, the complications were greater and the outcome less successful, suggesting that other approaches should be considered unless there are special indications for this procedure.

The issue of utilizing a temporary cement spacer after a knee resection arthrodesis of a highly malignant bone tumor is discussed. In our experience, this is the first type of reconstruction performed in the early days of the limb salvage. Now, after more than 12 years of follow-up based on the results of 84 patients, the usefulness and mechanical performance of this type of reconstruction are considered. Of these patients, 45 died of disease. Wound complications were present in 31% of the patients and led to amputation in 7 and healing failure in 6. Mechanical complications occurred in 39%, but radiographic analysis of the implant showed 32 cases (38%) with an inadequate spacer. Only 9 patients are still walking on the original reconstruction, 6 of them uncomplicated (the remaining 3 had rod migrations and shortening). The survival curve showed no statistical difference between the two groups (adequate vs inadequate spacer). In 33 patients who are still alive and retain their limb, the final functional results were excellent in 6, good in 8, fair in 14, and poor in 5. This type of reconstruction can still be considered in developing countries, or when a definitive arthrodesis is planned where there is a lack of a bone source (children, no bone bank). In our institution, reconstruction with cement is still suggested for patients with a large tumor around the knee, when the quadriceps is completely sacrificed, and the patient prognosis is markedly unfavorable.

Subtrochanteric fractures are a typical pathology in the elderly patient, they are not very common and they are difficult to treat. The general conditions of these patients, often at the limit of operability, are further compromised by surgery and time spent in bed, leading to the death of the patient in a high percentage of cases. The fracture is often spyroid, it has multiple fragments, with interruption of the medial cortical bone. The quality of the bone, because of the marked osteoporosis, does not guarantee the good hold of the means of fixation used. The use of intramedullary nailing is a safe method, that allows for stabilization of the fracture without excessive blood loss, it allows for early partial weight-bearing and it has a lower number of complications as compared to other methods. Between 1-1-97 and 31-12-00 a total of 59 persubtrochanteric fractures were treated; there were 15 males and 44 females. A Gamma Long nail was used in 46 cases, a Gamma Standard in 13. Eleven of the patients died within 6 months. A total of 27 patients aged an average of 78 years (minimum 65, maximum 87) were evaluated at a mean follow-up of 10 months (minimum 7, maximum 27). A Gamma Long nail had been used in 18 cases, and Gamma Standard in 8. Partial weight-bearing was allowed after a mean of 20 days (minimum 10, maximum 35), total weight-bearing after a mean of 60 days (minimum 40, maximum 75). Consolidation was obtained after a mean of 4 months (minimum 3, maximum 7). There were no significant complications.

Conjoined fracture-dislocation of the elbow were first described by Marotte in 1982. In this study, a total of 41 patients treated between 1975 and 1995 at the Rizzoli Orthopaedic Institute and 4 patients treated between 1997 and 2000 at the Division of Orthopaedics at the Maggiore Hospital are evaluated. Based on the Marotte classification, the patients are divided into 4 groups, by site of dislocation of the radial capitellum and amount of comminution of the fracture of the ulna. A clinical and radiographic evaluation was made after a mean follow-up of 5.3 years based on Anderson criteria. The results obtained were excellent in 17 patients (37.8%) satisfactory in 13 (28.9%), dissatisfactory in 12 (26.7%); 3 patients were considered to be failures (6.7%), the best results were obtained in type I anterior dislocations.

We describe 25 patients who were treated for a tumour of the proximal femur by resection and replacement with an uncemented, bipolar, modular prosthesis. When followed up after more than ten years four prostheses (16%) had required revision. Two joints showed wear and another necrosis of the acetabulum. One patient with loosening of the stem had been treated by radiotherapy to the femur. Articular cartilage seemed to be a reliable barrier to acetabular wear. Very few signs of the formation of particulate debris were observed. The most obvious feature in the bone-stem relationship was stress shielding, seen as osteoporosis of the proximal part of the femur around the stem in 68%. Functional activity was satisfactory in 68% of the patients. A better system of reattachment of the soft tissues is needed to avoid pain and a persistent limp.
