Sonoelastography in the diagnosis of tendinopathies: An added value

BACKGROUND: sonoelastography helps in the detection of abnormalities not yet evident on B-mode exam. METHODS: in this observational study, we report a collection of cases of symptomatic patients without alterations at ultrasound imaging but with evidence of pathological findings at sonoelastography. Patients, with clinical history suggestive for tendinopathies or surgically treated, and negative at the ultrasound exam, were submitted to sonoelastography. Out of 846, 632 patients with positive ultrasound exam were excluded. Sonoelastography was therefore performed in the remaining 214. RESULTS: the examination was positive in 168 cases: 78 patients were affected with shoulder diseases, while elbow pathology was observed in 31 subjects; patellar, Achilles and plantar fascia disorders were reported in 19, 27, and 13 patients, respectively. CONCLUSION: sonoelastography can reveal tendon abnormalities of clinical relevance in a high percentage of cases, where the ultrasound exam was negative, making the method a complementary tool to ultrasound evaluation

Pelvic bone surgery and natural delivery: absolute and relative contraindications

Objective. The gynecologist often involves the orthopaedic surgeon in the evaluation of pregnant women with previous medical history of pelvic surgery who will give birth. Young women can receive pelvic surgery for proximal femoral fractures, sacro-iliac or pelvic ring fractures, avascular necrosis of the femoral head, hip dysplasia and severe ankylosing spondylitis. The aim of this study is to determine whether such women can accomplish a natural delivery or should have caesarean delivery (C-section). Methods. Pubmed and the Cochrane Database of Reviews were searched for manuscripts including the years 1970 to present. Results. It is important to discriminate between pathological and/or post-surgical conditions affecting the coxo-femoral joint which constitute an absolute contraindication to vaginal delivery from other circumstances that may have a relative contraindication. Orthopaedic relative indications for C-section may include coxo-femoral pathologies where coxo-femoral joint range of motion is limited and women cannot assume a given position that is deemed necessary by the obstetric specialist for natural delivery. Conditions requiring C-section are those producing an insufficient width of the bony birth canal; when the transverse mid-pelvis diameter is <9.5 cm, then the probability of C-section is increased. Conclusions. It is not mandatory to perform a C-section in all women with a past medical history of pelvic surgery; accurate medical history collection, imaging technologies and ultrasound make it possible decide if a C-section is compulsory

Single-Dose Intra-Articular Administration of a Hybrid Cooperative Complex of Sodium Hyaluronate and Sodium Chondroitin in the Treatment of Symptomatic Hip Osteoarthritis: A Single-Arm, Open-Label, Pilot Study

INTRODUCTION: Intra-articular (i.a.) hyaluronic acid is an accepted conservative therapy for knee osteoarthritis (OA). This study evaluated the safety and efficacy of a single i.a. injection of an innovative formulation of sodium hyaluronate 2.4% plus sodium chondroitin non-sulphated 1.6% of biotechnological origin (HA-SC) for the treatment of patients with radiographically confirmed symptomatic hip OA and moderate-to-severe pain.METHODS: In this prospective, multicenter, open-label, pilot study, HA-SC was administered using a standard ultrasound-guided procedure. Adverse events, global/local evaluation of tolerability, and use of rescue analgesics were recorded. Efficacy endpoints included visual analogue scale (VAS) measurement of hip pain, changes in Lequesne's algofunctional Index, and assessment of global status.RESULTS: Treatment was well tolerated; adverse device events of moderate-to-severe intensity, most commonly, injection site pain/localized arthralgia occurred in 20.8% of subjects. Global evaluation of tolerability was rated as excellent or good (75.0%), fair (16.7%), and poor (8.3%) by subjects and 77.1, 14.6, and 8.3%, respectively, by investigators. There was a rapid and significant decrease in hip pain after a single injection; VAS pain score decreased from a mean of 67.5mm at baseline to 29.3mm by day 7, with the effects sustained during 6months of follow-up (P&lt;0.0001). There were significant improvements in Lequesne's Index for hip OA total scores at all time points during follow-up (P&lt;0.0001). The majority of subjects reported 'Very much improved' or 'Slightly improved' global improvement at any time point. Use of rescue paracetamol was generally low.CONCLUSIONS: A single i.a. injection of an innovative HA-SC formulation was well tolerated, safe, and effective in the treatment of symptomatic hip OA

Celecoxib versus indomethacin as prevention of arthrofibrosis. A perspective case-control study

Nonsteroidal anti-inflammatory drugs (NSAIDs) remain the most commonly utilised prophylaxis to reduce arthrofibrosis (AF) related to the inflammatory response which leads to a pathological condition called arthrofibrosis. Several NSAIDs have shown to be effective, although postoperative indomethacin has been the historical gold standard. More recently, credit has been given to the use of COX-2 selective inhibitors, due to concerns over gastrointestinal effects, as peptic ulcers, with non-selective COX. However, to date, few studies have compared the therapeutic effects of the two drugs. The aim of this study is to compare the postoperative administration of indomethacin and celecoxib in patients with diagnosis of AF treated with arthroscopic lysis and evaluate joint recovery. In this prospective study, 42 patients were diagnosed with hip, knee and elbow residual AF. The inclusion criteria were age > 18 years and a diagnosis of residual AF, following exposure to a previous traumatic event or surgical treatment; exclusion criteria were patients with 35 or < 18 kg/m2, affected by peripherical neuropathies and presence of heavy functional limitations, active infection, complex regional pain syndrome diagnoses. All patients underwent to arthroscopy, operated by a single surgeon with the same team in the same clinic and postoperatively were randomly divided into two groups, one treated with indomethacin, and the other with celecoxib. Of the patients examined, the following parameter was considered: joint range of motion (ROM) preintervention and post-intervention at 3 months and after 12 months. ROM was analysed with Student t test. The comparison of the ROM between both the 3 months postoperative groups has been shown to be not statistically significant. On the other hand, after 1 year, t-Student test referred to preoperative condition was significantly in favour of the group treated with celecoxib (p = 0.02). Lastly, neither celecoxib nor indomethacin showed any gastrointestinal side effects

Poly-L-lactic acid beta-tricalcium phosphate screws: a preliminary in vivo biocompatibility study.

The aim of this study is to assess the biocompatibility of two types of Poly-L-lactic acid (PLLA) screws (with either hydroxiapatite (HA) or β-tricalcium phosphate (β-TCP)) implanted in the left femur of four sheep euthanized at 42, 50, 57 and 84 days after surgery. Titanium screws were also implanted for comparison purposes. No signs of inflammation were seen in the 240 specimens. A rating of "+/-"for macrophages and "-"for neutrophils was assigned to all specimens. All specimens were assigned a rating which ranged from "+/-" to "+++" for fibroblasts and osteoblasts. The presence of macrophages, neutrophils and fibroblasts/osteoblasts was not statistically different for the four implantation periods. PLLA implants with β-TCP have a biocompatibility comparable to PLLA implants with HA

Pathogenesis of tendinopathies: inflammation or degeneration?

The intrinsic pathogenetic mechanisms of tendinopathies are largely unknown and whether inflammation or degeneration has the prominent role is still a matter of debate. Assuming that there is a continuum from physiology to pathology, overuse may be considered as the initial disease factor; in this context, microruptures of tendon fibers occur and several molecules are expressed, some of which promote the healing process, while others, including inflammatory cytokines, act as disease mediators. Neural in-growth that accompanies the neovessels explains the occurrence of pain and triggers neurogenic-mediated inflammation. It is conceivable that inflammation and degeneration are not mutually exclusive, but work together in the pathogenesis of tendinopathies

Interleukin-31: a new cytokine involved in inflammation of the skin.

Cytokines affect immune functions involved inmotility, chemotaxis, phagocytosis, cytotoxicityand antigen presentation (1). Interleukins (IL) arepleiotropic cytokines with diverse receptorsignaling pathways whose expression is controlledat multiple levels (2). Interleukin receptors (ILR)have intrinsic roles in regulating and amplifyingthe inflammatory response (3-12).Skin is the largest organ of the body with thespecific immune defense and its inflammatoryconditions include atopic dermatitis, allergies,psoriasis etc. (13-19). Infiltrated lymphocytesproliferate in an activated state in the skin lesion inan autocrine and/or paracrine manner and produceTH2-type cytokines that might evoke immunologicabnormalities (20-23)...
