Reliability and methodology of quantitative assessment of harvested and unharvested patellar tendons of ACL injured athletes using ultrasound tissue …

2019

Ultrasound tissue characterization (UTC) imaging has been previously used to describe the characteristics of patellar and Achilles tendons. UTC imaging compares and correlates successive ultrasonographic transverse tendon images to calculate the distribution of four color-coded echo-types that represent different tendon tissue types. However, UTC has not been used to describe the characteristics of patellar tendons after anterior cruciate ligament reconstruction (ACLR). The aim of this cross-sectional study was to assess the intra and inter-rater reliability of the UTC in unharvested and harvested patellar tendons of patients undergoing ACLR. Intra and inter-rater reliability of both UTC da…

COX-2 expression in chondrosarcoma: A role for celecoxib treatment?

2010

Chondrosarcomas are resistant to conventional chemo- and radiotherapy. A subset of chondrosarcomas arises secondarily in the benign tumour syndromes enchondromatosis (EC) and multiple osteochondromas (MO), and prevention of tumour development would greatly improve prognosis. We therefore investigated the effect of selective COX-2 inhibition on chondrosarcoma growth. COX-2 expression was studied in central- and peripheral cartilaginous tumours. The effect of COX-2 inhibition was assessed in four high-grade chondrosarcoma cell lines using celecoxib and NS-398 treatment. COX-2 activity (prostaglandin E-2 (PGE(2)) ELISA) and cell viability were measured. The (prophylactic) effect of celecoxib o…

Cementless acetabular reconstruction and structural bone-grafting in dysplastic hips. Surgical technique.

2007

BACKGROUND: Studies of acetabular reconstruction with use of cement and bulk bone graft have demonstrated increasing rates of cup failure in patients with dysplastic hips seven years after total hip arthroplasty. Comparable data on the long-term results of bulk bone-grafting done in conjunction with cementless implants are limited. The aim of this study was to review the clinical and radiographic results of autologous bulk bone-grafting in conjunction with a cementless cup. METHODS: From 1987 to 1992, forty-seven patients (forty women and seven men, with an average age of 50.4 years) who had developmental dysplasia of the hip underwent fifty-six total hip arthroplasties and received a struc…

MRI evaluation to predict tendon size for knee ligament reconstruction.

2017

Background The aim of this study is to evaluate a possible correlation between specific anthropometric parameters and sizes of knee tendons commonly used for ACL reconstruction. We hypothesized that specific clinical and radiological knee measurements could be better tendon sizes predictors than age, gender, height and weight. Materials and methods 100 consecutive patients were enrolled and 77 patients met the inclusion criteria of the study. All patients underwent a MRI of the knee with a 1.5 T super conducting MR System. For each patient, anthropometric data such as gender, height, weight, body mass index (BMI) and knee circumference were recorded. Specific MRI knee measurements were perf…

Evaluation of efficacy and biocompatibility of a new absorbable synthetic substitute as a dural onlay graft in a large animal model.

2016

Numerous dura substitutes are commercially available, but no absorbable synthetic dura repair product has been used for both onlay and suture applications.The safety and effectiveness of a new absorbable synthetic substitute composed of Poly-L-lactide microfibers as onlay dural graft were evaluated.Physical properties and performance of the microfibrous synthetic dural substitute implanted as an onlay or suturable grafts were compared with these commercial products, including CODMAN ETHISORB™ Dura Patch and DuraGen™ Dural Graft Matrix, in a canine duraplasty model. The cerebrospinal fluid (CSF) leakage, macroscopic and microscopic observation at 30 and 90 days after implantation were invest…

Treatment of Combined Medial and Lateral Collateral Ligament Insufficiency

2016

The medial and lateral collateral ligament complexes represent primary elbow ligament stabilizers. Injury to these structures may occur because of an elbow dislocation or due to a severe varus or valgus force. Most elbow dislocations are stable once reduced and may be treated conservatively. However, if the elbow remains unstable surgical treatment is recommended. Repair should be anatomical and should restore stability to the elbow in order to permit an early active range of motion. Reconstruction may be required in severe cases and where primary repair is not possible. Depending on the degree of instability, either one or both of the collateral ligament complexes may need to be repaired o…

Netaisnas iedzīvošanās institūta regulējums Civillikumā, tā salīdzinājums ar kopējā modeļa projektu (draft common frame of reference)

2017

Par netaisnu iedzīvošanos pēc neatkarības atjaunošanas Latvijā rakstīts ārkārtīgi maz. Izsmeļošākais avots ir Civillikuma saistību tiesību daļas komentāri, kuri gan arī sastādīti pirms vairāk nekā 16 gadiem. Tiesu prakse gan rāda, ka strīdi no netaisnas iedzīvošanās izceļas pietiekami bieži, tomēr šobrīd likumā atrodamā sistēma ir arhaiska, smagnēja un sadrumstalota. Eiropā ir izstrādāts Kopējā modeļa projekts (Draft Common Frame of Reference), kurš netaisnas iedzīvošanās regulējumam veltījis atsevišķu grāmatu. Darbā autore analizē netaisnas iedzīvošanās sistēmu Civillikumā un meklē efektīvāko regulējumu šim institūtam, salīdzinot to ar Kopējā modeļa izstrādāto netaisnas iedzīvošanās sistēm…

'We have a solution': Delivering on the promise to take national responsibility for nuclear waste management

2022

We examine the realization of the umbrella promise to assume national responsibility for the final disposal of spent nuclear fuel. Three case studies are used to illustrate how Finland delivers on the promise to take care of its own nuclear waste - a promise that has greatly contributed to the legitimacy of nuclear power in Finland. The article shows how this promise is being challenged by new competitors, business visionaries, and the public. The case studies illustrate the tensions between those who made the promise and the actors who interpret and mobilize the promise for varying purposes and under changing circumstances. We investigate techno-scientific promises by looking at debates ab…

"Mroczna otchłań". Archetypowa interpretacja opowiadania "Przemiana Juana Romero" Howarda P. Lovecrafta

2020

The setting of “The Transition of Juan Romero” – the short story by Howard Phillips Lovecraft, who was the originator of modern American horror fiction – is “the gold mine in the Cactus Range”. Drawing on the theories of Carl Gustav Jung, the author of the present interpretation amplifies the cultural dimensions of Lovecraft’s text, giving prominence to its origin from the ancient myths of the Aztecs, and using the so-called psychological alchemy to show the archetypal symbolism and structure of the story. Such a critical perspective, which takes into account different layers of the authorial intentionality and the reader’s response, reveals the complexity of the characters and situations, …
