Primary Hydatidosis Of The Tibia: A Tricky Diagnosis

Primary hydatidosis of the tibia is a rare disease. In an endemic area, it should be considered in the differential diagnosis of a hypolucent osteolytic lesion on xray. If not properly managed, anaphylactic shock may occur intraoperatively, as well as increased reccurence of the disease. This is a case report of a primary tibial hydatid cyst, treated first with curettage and phenolizaton, and then after recurrence, treated with total knee arthroplasty. We will review the literature of diagnosis and treatment of a hydatid cyst of the tibia

Total elbow arthroplasty in distal humeral nonunion: Clinical and radiographic evaluation after a minimum follow-up of three years

Background: Total elbow arthroplasties (TEAs) are usually indicated in chronic inflammatory arthropathies. This procedure has also recently been used in complex distal humeral fractures and nonunions in selected patients. This study analyzed the clinical and radiographic outcomes in patients treated for nonunions around the elbow region with a minimum follow-up of 3 years. Methods: Between May 2002 and June 2012, 20 patients affected with distal humeral nonunions were treated with TEA. All patients were assessed clinically using the Mayo Elbow Performance Score and radiographically to evaluate the positioning of the prosthetic components and signs of loosening. Statistical analyses were performed to investigate the presence of clinical and radiographic variables as predictive factors of poor functional outcomes. Results: The Mayo Elbow Performance Score of the affected arm improved significantly between the preoperative period and follow-up. Results were good or excellent in 90% of the patients even if a high rate of complications (30%) was encountered. The development of complications after surgery and stages II, III, and IV radiolucency, according to the Morrey criteria, were predictive factors of poor outcomes. Conclusions: According to the satisfactory results observed in this study, TEA could be indicated in selected patients aged older than 70 years with low functional demands and affected with distal humeral nonunions in which obtaining a stable fixation is difficult

Quadriceps tendon tear rupture in healthy patients treated with patellar drilling holes: clinical and ultrasonographic analysis after 36 months of follow-up

Background: quadriceps tendon subcutaneous rupture is an uncommon injury affecting predominantly middle-aged men as a result of direct or indirect trauma; aim of this work is to evaluate clinical outcome and tendon morphology in patients treated surgically with transpatellar drilling suture. Methods: 20 patients (20 male) with an average age of 54 (42-59) were evaluated with a mean follow-up of 36 months. Measurements of range of motion (ROM) and of tight circumference were collected. Lysholm and Rougraff Score were also performed. All the patients underwent a US evaluation the morphologic changes of the repaired tendon. Results: mean active ROM was 1°-117°; average difference in the circumference of the quadriceps was 2.6% 10 C and 3.3% 15 C. The mean Lysholm Score calculated was 88/100; the mean Rougraff Score 17/25. At ultrasonographic evaluation all tendons were continuous; heterotopic ossification was present in 18 quadriceps tendons. Thickness was augmented in 18 quadriceps tendons and in 5 patellar tendons. Vascularization was always conserved. Lateral subluxation of patella was reported in 1 case. Conclusions: patellar drilling holes repair is a nondemanding procedure, inexpensive and technically uncomplicated. US evaluation confirms tendon healing; tendon remodeling does not affect patient’s clinical outcome and quality of life

Dense water plumes SW off Spitsbergen Archipelago (Arctic) in 2014-2017

In the last decades, the Arctic region has gained a large interest because of climate changes and relevant effects on ice melting and global warming. Abrupt changes in the atmosphere are responsible for significant changes in ocean water masses and large-scale circulation patterns, which in turn affect the global climate. Studying ocean circulation and related processes along the west Svalbard slope and within the Storfjorden (south Svalbard Archipelago) is essential to describe the thermohaline circulation and the dense water formation (DWF) in the Arctic, and the way they contribute to the global thermohaline circulation. DWF processes in this region depend on the rate of cooling and homogenisation of the Atlantic water along its northwards pathway, brine rejection phenomena, boundary convection on the Arctic Ocean shelves and slopes, and deep open-ocean convection in the central gyres of the Greenland and Iceland Seas. This study focuses on brine rejection, shelf convection and entrainment processes, which occur on the west Svalbard margin and in the Storfjorden during the winter season. Two short (~140m) moorings (named S1 and ID2, figure 1) were deployed ~1000m deep along the slope in 2014, to collect multiannual time-series in an area of potential interaction between the West Spitsbergen Current and the descending dense shelf plumes. Four oceanographic cruises were carried out between 2014 and 2017 to integrate time-series with CTD (conductivity-temperature-depth) casts in the area. One purpose of this research activity was to study the role played by bottom currents in the formation of two sediment drifts (Isfjorden and Bellsund). At S1 and ID2, time-series revealed a large thermohaline and current variability during the winter period, from October to April. Our data highlight the presence of a stable signal of Norwegian Sea Deep Water (θ = -0.90°C, S = 34.90, σθ = 28.07 kg m-3) at 1000m depth, influenced by occasional intrusions of warmer (up to +2°C), saltier (up to ~35), and less dense (down to 27.98 kg m-3) water during fall-winter periods. Interestingly, such intrusions occur simultaneously at both sites, despite their distance (~170km), suggesting also that winter meteorological perturbations play an important role in triggering dense shelf plumes. In this paper, the origin, timing, and role of shelf turbidity plumes (denser than TS plumes), which descend along the slope and undergo a strong entrainment process that modify their properties will be discussed. The role of possible mesoscale processes and land-sea atmosphere interactions will also be investigated
