RESUMO

Introduction: Periprosthetic joint infection (PJI) represents a serious burden in orthopaedic oncology. Through the years, several local expedients have been proposed to minimise the risk of periprosthetic infection. In this study, we report our outcomes using topical vancomycin powder (VP) with the aim to prevent PJIs. Materials and methods: Fifty oncological cases treated with massive bone resection and the implant of a megaprosthesis were included in our study. Among them, 22 [(GGroup A) received one gram of vancomycin powder on the surface of the implant and another gram on the surface of the muscular fascia]. The remaining 28 did not receive such a treatment (Group B). The rest of surgical procedures and the follow-up were the same for the two groups. Patients underwent periodical outpatient visits, radiographs and blood exams' evaluations. Diagnosis of PJIs and adverse reactions to topical vancomycin were recorded. Results: None of the cases treated with topical vancomycin developed infections, whereas 6 of the 28 cases (21.4%) who did not receive the powder suffered from PJIs. These outcomes suggest that cases treated with VP had a significantly lower risk of post-operative PJI (p=0.028). None of our cases developed acute kidney failures or any other complication directly or indirectly attributable to the local administration of VP. Conclusions: The topical use of vancomycin powder on megaprosthetic surfaces and the overlying fascias, alongside with a correct endovenous antibiotic prophylaxis, can represent a promising approach in order to minimise the risk of periprosthetic infections in orthopaedic oncology surgery.

RESUMO

PURPOSE OF THE STUDY: Pelvic reconstructions after massive bone resections are among the most challenging practices in orthopedic surgery. Whether the bone gap results after a trauma, a tumor resection, or it is due to a prosthetic revision, it is mandatory to reconstruct pelvic bone continuity and rebuild the functional thread that connects spine and hip joint. Several different approaches have been described in literature through the decades to achieve those goals. MATERIAL AND METHODS: To this date, 3D-printed implants represent one of the most promising surgical technologies in orthopedic oncology and complex reconstructive surgery. We present our experience with 3D-printed custom-made pelvic prostheses to fulfi ll bone gaps resulting from massive bone loss due to tumor resections. We retrospectively evaluated 17 cases treated with pelvic bone reconstruction using 3D-printed prostheses. Cases were evaluated in terms of both oncological and functional outcomes. RESULTS: At the last follow-up, local complications were found in 6 cases (36%): in 4 (23.5%) of them the cause was a local recurrence of the disease, whereas only 2 (12.5%) had non-oncologic issues. The mean MSTS score in our population increased from 8.2 before surgery to 22.3 at the latest clinical control after surgery. DISCUSSION: 3D-printing technology, used to produce cutting jigs and prosthetic implants, can lead to good clinical and functional outcomes. These encouraging results are comparable with the ones obtained with other more frequently used reconstructive approaches and support custom-made implants as a promising reconstructive approach. CONCLUSIONS: Our data confi rm 3D-printing and custom-made implants as promising technologies that could shape the next future of orthopedic oncology and reconstructive surgery. KEY WORDS: custom made prosthesis, pelvic reconstruction, orthopedic oncology, cutting jigs, 3D-printing.

RESUMO

Giant cell tumour (GCT) represents 5% of all primitive bone tumours. Standard surgical treatment of GCT includes intralesional excision or segmental resection. Curettage has a higher recurrence rate (10-25% in stage 2 or 3 but does preserve adjacent joint function. The use of local adjuvants such as phenol, alcohol, H2O2, Argon or cement may decrease recurrence rate, yet which local adjuvant works best is still, to this day, controversial. A series of 109 patients with GCT of the extremity, surgical treated in a single Institution from 2016 to 2018, were analysed in a retrospective study. The purpose of our study was to report the incidence of recurrence rate in patients with GCT of limbs treated in a single institution with different local adjuvants. The results of the present study suggests that curettage in association to cryoablation seems to reduce the recurrence rate compared to "classic" local adjuvants.

RESUMO

PURPOSE: Shoulder instability and reduced range of motion are two common complications of a total reverse shoulder arthroplasty. In this work, a new approach is proposed to estimate how the glenoid component positioning can influence the stability and the range of motion of a reverse shoulder prosthesis. MATERIALS AND METHODS: A standard reverse shoulder prosthesis has been analysed. To perform virtual simulation of the shoulder-prosthesis assembly, all the components of the prosthesis have been acquired via a 3D laser scanner and the solid models of the shoulder bones have been reconstructed through CT images. Loads on the shoulder joint have been estimated using anatomical models database. A new virtual/numerical procedure has been implemented using a 3D parametric modelling software to find the optimal position of the glenosphere. RESULTS: Several analyses have been performed using different configurations obtained by changing the glenoid component tilt and the lateral position of the glenosphere, modified through the insertion of a cylindrical spacer. For the analysed case study, it was found that the interposition of a spacer (between the baseplate and the glenoid) and 15° inferior tilt of the glenosphere allow improving the range of motion and the stability of the shoulder. CONCLUSIONS: Some common complications of the reverse shoulder arthroplasty could be effectively reduced by a suitable positioning of the prosthesis components. In this work, using a new method based on virtual simulations, the influence of the glenosphere positioning has been investigated. An optimal configuration for the analysed case study has been found. The proposed approach could be used to find, with no in vivo experiments, the optimal position of a reverse shoulder prosthesis depending on the different dimensions and shape of the bones of each patient.

RESUMO

Treatment of bone metastases is often palliative, aiming at pain control and stabilization or prevention of pathological fractures. However, a complete resection with healing purposes can be performed in selected cases. The aim of our work was to evaluate the survival of megaprostheses used for reconstruction after bone metastases. Between January 2001 and March 2015, we implanted 169 Megasystem-C® (Waldemar LINK® GmbH & Co. KG, Hamburg, Germany) after bone metastasis resection. Patients, 95 females and 74 males, were operated at an average age of 61 (12-87) years for proximal femoral resection in 135 (79.9%) cases, distal femur in 24 (14.2%), proximal tibia in 6 (3.6%), total femur in 3 (1.8%) and intercalary femur in 1 (0.6%). Mostly, breast cancer metastases (30.8%), kidney (17.8%) and lung (14.2%) were treated. At an average follow-up of 21 (1-150) months, we found a 99.4% overall limb salvage and a 96.1% overall survival rate at 1 year, 92.8% at 2 years, and 86.8% at 5 and 10 years. We found 9 (5.3%) mobilization cases of the proximal femoral implant, 3 needed surgical reduction; 2 (1.2%) cases of aseptic loosening of the prosthetic stem; 2 (1.2%) periprotetic infection cases, one requiring a 2-stage revision. Few literature studies have evaluated the survival of megaprosthetic implant in the treatment of bone metastases. Our data show how in this specific context the rate of complications is significantly lower than expected in general orthopedic orthopedic surgery. The use of modular prostheses is a valid reconstructive strategy after bone metastasis resection in selected patients. The rate of short-term complications is exceptionally low; further studies will have to confirm this in the longer term.

RESUMO

Common variable immune deficiency (CVID) is the most frequent primary immunodeficiency in adults. In CVID, the prevalence of gastrointestinal manifestations ranges between 2 and 50% with a complication-related morbidity second only to that of the respiratory tract. In some cases, clinical and endoscopic features are undistinguishable from those of inflammatory bowel disease (IBD). We describe the case of a 28-year-old man in which a diagnosis of Crohn's disease was firstly suspected. Subsequently, a diagnosis of Crohn's-like disease in a patient with CVID was made and a replacement therapy with human normal immunoglobulin intravenously was started. Unfortunately, serum IgG levels remained below 2.0 g/l in pre-infusional controls with persistence of gastrointestinal symptoms and malnutrition despite anti-inflammatory therapy (mesalazine, corticosteroids). Then, the patient began treatment with human normal immunoglobulins administered subcutaneously. The follow-up visits showed a progressive increase in serum IgG. Moreover, the patient reported improvement of gastrointestinal symptoms with reduction of diarrhoea, and laboratory tests showed a progressive and significant improvement. We confirm that therapy with subcutaneously administered immunoglobulins is safe and effective. In addition, our observations indicate that, for patients with CVID and enteropathic complications, replacement therapy with subcutaneous IgG may be the treatment of choice.

RESUMO

During the past decade, total knee arthroplasty (TKA) has been markedly increased. Recently, patient-specific custom cutting guides have been commercially introduced in order to achieve an accurate component alignment during TKA. In fact, these cutting blocks are specific to a patient's knee anatomy and should help the surgeons to perform bone cuts, reducing the complexity of conventional alignment and sizing tools. Nevertheless, there are critical arguments against patient-specific cutting guides for routine use, such as poor evidence and higher costs. Additionally, there are still no mild and long-term results available that describe the clinical outcomes following patient-specific instrumentation of TKR, cost-effectiveness and lower revision rates. Aim of the current manuscript was to describe the recent improvements of the surgical technique and instrumentation of TKA, reviewing the recent literature concerning the PSI technology.

RESUMO

The incidence of fractures of the humerus has increased exponentially in recent years. The most used classifications for humerus fracture are morphological (Neer), biological (AO/ASIF) and descriptive (Hertel). The types of surgical treatment for humerus fracture include prosthetic replacement and synthesis using different devices, including the Tension Guide Fixator (TGF), Gex-Fix. External fixation for displaced proximal humeral fractures avoids dissection and soft tissue stripping and has been reported by some authors to be associated with higher union rates, a lower incidence of avascular necrosis, less scarring of the scapulohumeral interface, and faster rehabilitation compared with open reduction and internal fixation. Other authors have reported that external fixation does not ensure acceptable reduction and fracture stability, particularly in patients with osteoporosis. The external fixation technique involves the introduction of Steinmann's pin to keep manual reduction, the introduction of two K-wires in the humeral head, the removal of the Steinmann's pin, and the introduction of two fiches on the humeral shaft. Hub connectors are mounted on the wires and on the chips to connect the outer bar and tensioning system. A total of 84 patients aged 42-84 years with proximal end humeral fractures (66% had two-part fractures) were treated with Fixator TGF in this study from December 2007 to June 2012. The postoperative recovery was earlier and the active-assisted motion was less painful than has been reported with other surgical techniques. The TGF was removed without anaesthesia at the outpatient clinic at a mean of 7 weeks (range 5-8 weeks) after surgery, and there was no loss of reduction or secondary displacement after removal. These results, after five years of experience, confirm that the best indication for this fixator is two- or three-part fractures because the device enables early active mobilisation. The limitations of this fixator are evident in fractures in which closed reduction is not possible and in three-part fractures with varus displacement because the TGF has less stability than other systems, such as the plate or cage. The short learning curve, reduced surgical time and risk, and low cost encourage the use of this technique.

RESUMO

BACKGROUND: Ulcerative colitis (UC) is characterised by impaired fatty-acid oxidation; l-carnitine has a key role in fatty-acid metabolism and short-chain fatty acids such as butyrate and propionate are important energy source for intestinal epithelial cells. AIM: To evaluate efficacy and safety of colon-release propionyl-L-carnitine (PLC) in patients with mild-to-moderate UC receiving stable oral aminosalicylate or thiopurine therapy. METHODS: In a multicentre, phase II, double-blind, parallel-group trial, patients were randomised to receive PLC 1 g/day, PLC 2 g/day or placebo. Main inclusion criteria were as follows: age 18-75; disease activity index (DAI) score 3-10 inclusive, be under oral stable treatment with aminosalicylate or thiopurine. The primary endpoint was clinical/endoscopic response, defined as a decrease in DAI score ≥ 3 points or remission, defined as a DAI score ≤ 2 with no individual sub-score > 1. RESULTS: Of 121 patients who were randomised, 57 of 79 (72%) patients receiving PLC (combined 1 g and 2 g cohort) had a clinical/endoscopic response vs. 20 of 40 (50%) receiving placebo (P = 0.02). Specifically, in PLC 1 g/day group, 30 of 40 (75%) patients had clinical/endoscopic response (P = 0.02 vs. placebo) and 27 of 39 (69%) in the PLC 2 g/day group (P = 0.08 vs. placebo). Rates of remission were 22/40 (55%), 19/39 (49%), 14/40 (35%) in the PLC 1 g, PLC 2 g, and placebo groups, respectively. PLC had a similar safety profile to placebo; the most common adverse events were gastrointestinal. CONCLUSION: Propionyl-L-carnitine 1 g/day should be investigated further as a co-treatment for mild-to-moderate ulcerative colitis (NCT-01026857).

RESUMO

Herbal medicines are widely used in the world and are generally considered effective and safe, although many studies have demonstrated their potential toxic effects, particularly for the liver. We present a case of a woman, who developed a mixed cholestatic/hepatocellular liver injury due to herbal products. Firstly, she was admitted to Division of Surgery for right upper abdominal pain and jaundice and, for the suspect of biliary obstruction, she underwent to cholecystectomy. For persistence of liver enzymes elevation, she was admitted to our Gastroenterology Unit. We excluded every etiologies of hepatitis and, after an intensive dialogue with the patient, we obtained a history of herbal medicines use. Then, we performed a liver biopsy which was compatible with hepatotoxic injury. Therapy with ursodeoxycholic acid (UDCA) was started. Liver function tests returned to normal in two months. We describe this clinical case to encourage the communication doctor/patient in phytotherapy area and physician knowledge about efficacy and side effects of herbal medicine to avoid delayed diagnosis.

RESUMO

OBJECTIVE: Two common factors, cigarette smoking and appendectomy, have been found to play a role in ulcerative colitis (UC). Data on their role in the development of extraintestinal manifestations (EIM) are scarce. METHODS: The relationship between cigarette smoking, appendectomy, and EIM was examined in a prospective study involving 535 (M/F = 319/216) consecutive UC patients followed up for 18 yr. We considered the major EIM: seronegative spondyloarthropathy, pyoderma gangrenosum/erythema nodosum, acute anterior uveitis, and primary sclerosing cholangitis. We excluded patients with a history of EIM or those colectomized before study entry, ex-smokers, and those who started to smoke during the course of UC. RESULTS: In UC patients, seronegative spondyloarthropathy and dermatologic complications were found increased in smokers (p < 0.0001; p = 0.001) or in subjects with appendectomy (p = 0.0003; p = 0.02), while acute anterior uveitis and primary sclerosing cholangitis did not differ. The Kaplan-Meier analysis showed 18-yr rates for EIM of 71% in smokers and 45% in nonsmokers (log-rank test, p = 0.0001), and of 85% in patients with appendectomy and 48% in those without (p = 0.0001). Cox proportional-hazard model showed that cigarette smoking and appendectomy are independent factors promoting EIM. In smokers with appendectomy the adjusted hazard ratio (3.197, 95% CI 1.529-6.684) was higher than in patients with appendectomy alone (2.617, 95% CI 1.542-4.442) or smoking alone (1.947, 95% CI 1.317-2.879). CONCLUSIONS: In UC patients, appendectomy and cigarette smoking are prognostic factors for the development of EIM. The unfavorable effect of cigarette smoking on EIM is additive to that of appendectomy.

RESUMO

AIM: To explore the efficacy and safety of the topically acting steroid beclometasone dipropionate (BDP) in an oral controlled release formulation in the treatment of extensive or left-sided ulcerative colitis. METHODS: In a multicentre, randomised, parallel-group, single-blind study, patients with active mild to moderate ulcerative colitis were randomised to a 4-week treatment with BDP 5 mg/day o.d. vs. 5-ASA 0.8 g t.d.s. The primary efficacy variable was the decrease of Disease Activity Index (DAI) (clinical symptoms and endoscopic appearance of mucosa). Safety was evaluated by monitoring adverse events, vital signs, haematochemical parameters and adrenal function. RESULTS: One hundred and seventy-seven patients were enrolled and randomly treated with BDP (n = 90) or 5-ASA (n = 87). Mean DAI score decreased in both treatments groups (P < 0.0001 vs. baseline for both groups). Clinical remission was achieved in 63.0% of patients in the BDP group vs. 62.5% in the 5-ASA group. A significant DAI score improvement (P < 0.05) in favour of BDP was observed in patients with extensive disease. Both treatments were well tolerated. Mean plasma cortisol levels were significantly reduced vs. baseline in BDP recipients, but without signs of pituitary-adrenal function depletion. CONCLUSION: Oral BDP gave an overall treatment result in patients with active ulcerative colitis without signs of systemic side-effects.

RESUMO

BACKGROUND: Allergic diseases and seronegative spondyloarthropathies are frequently observed in ulcerative colitis (UC). In this report we have investigated possible relationships between IgE-mediated allergic disease (AD), allergic contact dermatitis (ACD) and seronegative spondyloarthropathy (SpA) in UC patients at different grades and extensions of mucosa inflammation. METHODS: Forty-five UC consecutive outpatients were graded according to clinical, endoscopic and histologic activity scores. SpA was diagnosed according to the European Spondyloarthropathy Study Group criteria. AD was detected by skin prick tests and confirmed by specific provocation tests, while ACD was diagnosed using the European standard series of patch tests. Thirty-seven patients' spouses or partners served as controls. RESULTS: Fourteen patients and 1 control subject showed SpA (P = 0.001). Diagnosis of rhinitis, conjunctivitis or asthma was made in 19 patients and in 5 controls (P = 0.004), while ACD was found in 10 and in 4 (P = 0.17), respectively. In UC, AD coexisted with SpA in 2 cases (P = 0.01), AD with ACD in 1 case (P = 0.03) and ACD with SpA in 5 (P = 0.24). CONCLUSIONS: Notwithstanding the high frequency of AD and SpA found in UC, the concurrence of AD with SpA or ACD is an unusual finding, while SpA and ACD may coexist. These data suggest that, in UC, atopy and seronegative arthritis, as well as atopy and delayed-type allergy, are strongly polarized conditions tending to mutual exclusion. In UC, the presence of AD without SpA or ACD, and of SpA or ACD without AD may indicate subgroups of patients in which T-helper-2 cell or T-helper-1 cell responses predominate.

RESUMO

AIM: To evaluate efficacy and safety of oral beclometasone dipropionate (BDP) when added to 5-ASA in the treatment of patients with active ulcerative colitis. METHODS: In a 4-week, placebo-controlled, double-blind study, patients with extensive or left-sided mild to moderate active ulcerative colitis were randomized to receive oral 5-ASA (3.2 g/day) plus BDP (5 mg/day) or placebo. Clinical, endoscopic and histologic features, and haematochemical parameters were recorded at baseline and at the end of the study. RESULTS: One hundred and nineteen patients were enrolled and randomly treated with BDP plus 5-ASA (n = 58) or placebo plus 5-ASA (n = 61). Both treatment groups showed a statistically significant decrease of disease activity index (DAI) and histology score at the end of treatment (P = 0.001, each). DAI score was lower in the BDP group than in the placebo group (P = 0.014), with more patients in clinical remission in the BDP group (58.6% vs. 34.4%, P = 0.008). Serum cortisol levels significantly decreased in BDP group vs. baseline (P = 0.002), but without signs of pituitary-adrenal function depletion. A low incidence of adverse events was observed in both groups. CONCLUSIONS: Oral BDP in combination with oral 5-ASA is significantly more effective than 5-ASA alone in the treatment of patients with extensive or left-sided active ulcerative colitis.

RESUMO

A 53-year-old male presenting with a 3-month history of intermittent mild rectal bleeding was found, on double contrast barium enema, to have a large polyp on a long stalk in the sigmoid colon. Large bowel endoscopy confirmed the presence of a 2 cm pedunculated polyp which was removed using a diathermic snare, with slight bleeding following the procedure that did not require endoscopic haemostasis. Only after histologic examination was the polyp shown to be a colonic arteriovenous malformation. Endoscopically, arteriovenous malformations generally appear as flat or elevated bright red lesions. A pedunculated polypoid appearance is extremely uncommon. In this case, no gastrointestinal bleeding or polypoid recurrence was observed during the 12 months of clinical and endoscopic follow-up.

RESUMO

BACKGROUND: Diabetes, gallstones and dyslipidaemia are widespread, metabolically related, disorders that can affect the liver, often in a clinically silent fashion. AIM: To investigate whether the presence of these disorders may worsen chronic viral disease by inducing additional liver damage, revealed by variations in serum increases of aminotransferase, alkaline phosphatase and gamma-glutamyl-transpeptidase activities. PATIENTS AND METHODS: This retrospective, cross-sectional study involved 1,195 patients with chronic hepatitis C virus infection: 47.2% chronic hepatitis, 45.2% cirrhosis, and 7.6% hepatocellular carcinoma. 14.9% of patients had enzymatic cholestasis, defined as combined increase of alkaline phosphatase and gamma-glutamyl-transpeptidase. A Log-linear statistical model was applied to the following variables: stages of liver disease, diabetes, cholelithiasis, hypertriglyceridaemia, hypercholesterolaemia, and enzymatic cholestasis. RESULTS: Log-linear analysis, applied to categorical variables, revealed, for the first time, a three-way interaction between the stages of chronic liver disease, diabetes, and enzymatic cholestasis. Two-way interactions demonstrated that liver disease stages correlated directly to the prevalence of cholelithiasis and inversely to hypercholesterolaemia. Irrespective of the liver disease stage, hypertriglyceridaemia correlated to hypercholesterolaemia. CONCLUSIONS: This study discloses a synergistic liver damaging effect of diabetes and hepatitis C virus. The three-way interaction obtained by our analysis suggests that diabetes is a risk factor for the progression of viral liver disease and that it contributes to disease evolution, at least in part, by induction of cholestasis.

RESUMO

OBJECTIVE: In active ulcerative colitis (UC), magnetic resonance imaging (MRI) with ferumoxil, a superparamagnetic oral contrast agent, accurately evaluates, in our experience, the increased wall thickness and frequently shows a stronger perivisceral fat signal intensity (PFSI). The aim of our study was to evaluate the clinical significance of these MRI findings in active UC. METHODS: Twenty-four consecutive patients affected by moderate pancolitis were enrolled. At entry, each patient underwent MRI with ferumoxil to evaluate wall thickness and PFSI. Two groups of patients were individuated: group A (increased PFSI) and group B (normal PFSI). After obtaining remission, the number of relapses and, at each flare-up, the clinical activity index (CAI) were evaluated in all patients in a 2-yr follow-up period. The mean CAI was calculated at the end of the follow-up in each patient. Where there was colectomy, a complete histological examination of the colon was performed. RESULTS: PFSI was increased in 16 patients (group A) and was normal in the remainder (group B). There was a significant difference of wall thickness, number of relapses/yr, and mean CAI between the two groups of patients. No difference was observed with regard the duration of disease. Six patients of group A and no patient of group B underwent colectomy. The histological evaluation showed an increased thickness of the entire colonic wall with significant changes of the perivisceral fat structures. CONCLUSIONS: An increased

RESUMO

Systemic glucocorticosteroids have demonstrated efficacy in ulcerative colitis (UC) but cause undesired systemic side effects. Beclomethasone dipropionate (BDP) has potent topical activity and is extensively metabolized. This randomized double-blind study investigated an oral gastroresistant controlled-release preparation of BDP in 57 patients with mild to moderately severe extensive or left-sided UC. Patients were assigned to receive BDP 5 or 10 mg/d; a third group took a clinically inactive dose (1.6 g/d) of 5-aminosalicylic acid (5-ASA). Both BDP doses displayed excellent efficacy confirmed by results of endoscopy, biopsy, and clinical evaluation. Significant improvement from baseline occurred in most signs and symptoms of UC, particularly stool frequency, rectal bleeding, and mucus in the stool (P<.01). Tolerability was good in both BDP groups. Morning plasma cortisol levels decreased significantly from baseline with BDP 10 mg, but no significant changes in vital signs were observed at the end of treatment. Despite a small sample size and the open comparison with 5-ASA, this multicenter study showed the therapeutic equivalence of BDP 5 and 10 mg/d in alleviating clinical symptoms and improving endoscopic and biopsy scores in patients with mild to moderate UC. BDP 5 mg/d displayed better general tolerability and less reduction of plasma cortisol levels, however, and may be preferable to the higher dose in this indication.
