Multidisciplinary management of pyogenic spondylodiscitis: epidemiological and clinical features, prognostic factors and long-term outcomes in 207 patients

Abstract: Pyogenic spondylodiscitis (PS) is a potentially life-threatening infection burdened by high morbidity rates. Despite the rising incidence, the proper management of PS is still controversial. Aim of this study was to describe the clinical features of PS and to evaluate the prognostic factors and the long-term outcomes of a large population of patients. 207 cases of PS treated from 2008 to 2016 with a 2-year follow-up were enrolled. Clinical data from each patient were recorded. The primary outcome was the rate of healing without residual disability. Secondary outcomes included length of stay, healing from infection, death, relapse, and residual disability. Binomial logistic regression and multivariate analysis were used to evaluate prognostic factors. Median diagnostic delay was 30 days and the rate of onset neurological impairment was 23.6%. Microbiological diagnosis was established in 155 patients (74.3%) and the median duration of total antibiotic therapy was 148 days. Orthopedic treatment was conservative for 124 patients and surgical in 47 cases. Complete healing without disability was achieved in 142 patients (77.6%). Statistically confirmed negative prognostic factors were: negative microbiological culture, neurologic impairment at diagnosis and underlying endocarditis (p ≤ 0.05). Healing from infection rate was 90.9%, while residual disabilities occurred in 23.5%. Observed mortality rate was 7.8%. The microbiological diagnosis is the main predictive factor for successful treatment. Early diagnosis and multidisciplinary management are also needed to identify underlying aggressive conditions and to avoid neurological complications associated with poorer long-term outcomes. Despite high healing rates, PS may lead to major disabilities still representing a difficult challenge. These slides can be retrieved under Electronic Supplementary material.

Cross-cultural adaptation and validation of the Italian versions of the Kujala, Larsen, Lysholm and Fulkerson scores in patients with patellofemoral disorders.

Abstract: The Kujala, Fulkerson, Larsen and Lysholm questionnaires have been demonstrated to be reliable and sensitive in assessing patients with patellofemoral pathology The purpose of this study is to translate and cross-culturally adapt into Italian the English versions of the Kujala, Fulkerson, Larsen and Lysholm questionnaires, and undertake reliability and validity evaluations of the Italian versions of these scores in patients with patellofemoral pathology The cross-cultural adaptation process was carried out following the simplified Guillemin criteria The questionnaires were administered to 63 patients with either patellar instability or painful patella syndrome To assess the validity of the questionnaires, they were compared with the Oxford knee score The questionnaires were administered to a subsample of 33 patients 5 days later to assess test–retest reliability The interclass coefficient correlation was 096 for the Kujala score, 092 for the Larsen score, 096 for the Lysholm score, 094 for the Fulkerson score (P < 001), and 083 for the Oxford score Pearson’s correlation was096 between the Kujala and Oxford scores, 090 between the Larsen and Oxford scores, 094 between the Lysholm and Oxford score, and 093 between the Fulkerson and Oxford scores Responsiveness, calculated by standardized response mean, was 12, and effect size was 14 The Italian versions of the Kujala, Larsen, Lysholm and Fulkerson scoring systems were shown to be equivalent to their English versions and demonstrated good validity, reliability and responsiveness to surgical treatment of patellofemoral pathology To the best of the authors’ knowledge, this is the first attempt to adapt four of the most common patellofemoral-specific scoring scales to the Italian language Level II

Single dose cefazolin is safe and effective for pre-operative prophylaxis in orthopaedic oncology.

Abstract: Surgical site infections (SSI) are a common potentially preventable complication after surgical procedures. A standardized antibiotic prophylaxis in elective orthopaedic surgery plays a major role in lowering SSI. At present, there is little published evidence regarding standardized antibiotic prophylaxis in orthopaedic oncological surgery. We introduced a prophylactic antibiotic protocol for orthopaedic oncological surgery in our hospital. The proposed protocol consists in "one-shot" intravenous administration of Cefazolin 2g, 30 min before surgery. In our setting, this preoperative antibiotic prophylaxis regimen was associated with a markedly lower rate of SSI's. There is no current evidence in favour of greater effectiveness of prophylaxis beyond 24/48 h after surgery compared to our pre-surgical "one-shot" administration; by contrast, prolonged post-surgical prophylaxis is likely to undermine the patient's bacterial flora and select resistant pathogens. These results are preliminary and should be used to start planning a standardised prophylactic protocol to prevent SSI's after orthopaedic oncological surgery.

Intramedullary nailing of tibial shaft fractures in the semi-extended position using a suprapatellar approach: A retrospective case series.

Abstract: Tibial shaft fractures are extremely common injuries. High rate of union, acceptable alignment in all planes, and a low complication rate have been reported when diaphyseal fractures are treated by intramedullary nailing. However, knee pain after tibial nailing has historically been problematic. While the exact aetiology of the knee pain is still unknown, surgical approach relative to the patellar tendon, nerve transection, violation of the fat pad or joint capsule as well as nail diameter and implant prominence have been claimed as possible causes. Therefore, establishing an appropriate starting point remains a crucial step in the surgical procedure. Recently, suprapatellar nailing in the semi-extended position has been suggested as a safe and effective surgical technique. Literature is lacking on this topic, therefore the present article discusses clinical outcomes of 25 patients treated by suprapatellar nailing at 2 years follow up and a literature review.

Secondary femur fracture following treatment with anterograde nailing: the state of the art.

Abstract: Cephalomedullary nailing (CMN) currently represents the best surgical technique for the treatment of intertrochanteric hip fractures. Although the success of CMN in terms of functional recovery and fracture healing, in clinical practice there are many complications. Later femur fracture following treatment of trochanteric fracture with CMN is not a very frequent complication but, when it occurs, its treatment is the most complex, because of the increase of peri-operative mortality. There are studies in literature, which have demonstrated that the incidence of this complication is about 0.5-3%. Diagnosis and classification are made with standard radiographs, using the AO classification and the modified Vancouver classification. In the actual literature, to determinate the predisposing factor to the secondary fractures, the authors focused their attention on patient-related and surgical related risk factors. The treatment is variable and it depends on the type and characteristics of fracture and device. Outcomes analyzed in literature were mortality and bone healing. The aim of this manuscript is to provide an overview of this topic and to describe the state of the art of the secondary fracture after surgical treatment with intramedullary nailing.

Mueller-Weiss disease: review of the literature.

Abstract: Muller-Weiss (MW) disease is a spontaneous osteonecrosis of the tarsal navicular bone in adults. It is a rare cause of chronic medial midfoot pain and deformity characterized by the collapse of the dorso-lateral part of the navicular, progressive navicular fragmentation and talonavicular joint destruction. This study provides a review of the literature about the epidemiology, etio-pathogenesis, clinical, radiological findings and therapeutic alternatives.

Malnutrition is prevalent in patients with cardiorenal syndrome and negatively influences clinical outcome.

Abstract: Cardiorenal syndrome (CRS) describes the concurrent failure of cardiac and renal function, each influencing the other. Malnutrition and cachexia frequently develop in patients with heart failure or kidney failure. However, no information is currently available on the prevalence of malnutrition in CRS patients. We studied CRS patients admitted to an internal medicine ward during a 5-month period and evaluated their clinical characteristics and nutritional status. Malnutrition risk was assessed by using the validated screening tool NRS-2002 whilst body composition was assessed by bioimpedance analysis and muscle function was measured by handgrip (HG) strength. Cardiac mass was also recorded. Length of stay, hospital readmission and 6-month mortality were registered. During the study period, 22 CRS patients were studied. Twenty patients were diagnosed with either CRS type 1 or CRS type 5. In CRS patients, fat-free mass showed a trend toward representing a protective factor for 6-month mortality (OR=0.904; p=0.06). Also, fat-free mass correlated with HG strength and cardiac ejection fraction. Malnutrition risk was diagnosed in 45% of the patients, whereas 8 patients met the definition of cachexia. Even without statistical significance, CRS patients with malnutrition had lower BMI (Body Mass Index) (p=0.038) and fat-free mass (p= n.s.). However, CRS malnutrition was associated to higher 6-month mortality (p= 0.05), and appears to negatively influence the outcome in CRS (OR= 9; p= 0.06). Our results show that malnutrition is prevalent in CRS patients and influences the clinical outcome. The assessment of nutritional status, and particularly body composition, should be implemented in daily practice of patients with CRS.
