Results of isolated posterolateral corner reconstruction

2010

Abstract Background Isolated posterolateral corner (PLC) tears are relatively rare events. Various surgical techniques to treat posterolateral knee instability have been described; because surgical results are linked to cruciate reconstructions it has been difficult to date to define whether one surgical procedure has better prognosis than another. The goal of this study is to determine the clinical outcome of PLC reconstruction following fibular-based technique. Materials and methods We retrospectively evaluated a case series of patients who received isolated PLC reconstruction between March 2005 and January 2007. Ten patients were surgically treated for isolated injuries and were availabl…

Trattamento Percutaneo Ecoguidato (TPE) di borsite calcifica del legamento collaterale mediale del ginocchio: case report.

2019

INTRODUZIONE Il dolore in regione mediale del ginocchio è una condizione di frequente riscontro nella pratica clinica. Numerose sono le strutture presenti in tale regione anatomica e le relative patologie a esse correlate che possono essere responsabili dell’insorgenza di dolore. Tra di esse, la borsite del legamento collaterale mediale di ginocchio è una condizione di non frequente riscontro ma che deve essere tenuta in considerazione in presenza della suddetta sintomatologia (1). La borsa del legamento collaterale mediale è una struttura situata tra i due strati che compongono il legamento, lo strato profondo e lo strato superficiale (2). Brantigan and Voshell per primi identificarono la …

Perceived problems with collateral: The value of informal networking

2020

Abstract Many businesses in emerging economies are financially constrained due to their limited use of formal loans. Recent evidence suggests that negative perceptions discourage entrepreneurs from applying for loans. One of the main issues entrepreneurs mention is unattainable collateral requirements. In this paper, we contribute to this line of research by investigating the effect of networking with fellow entrepreneurs on perceived collateral problems. Drawing on quantitative and qualitative data originating from female entrepreneurs in Tanzania, we find that through networking, entrepreneurs are exposed to stories of their peers’ experiences with loans which influence their perceptions …

Retrograde Chronic Total Occlusion Percutaneous Coronary Interventions: Predictors of Procedural Success From the ERCTO Registry

2022

Objectives: The aim of this study was to identify independent predictors of procedural success after retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Background: Retrograde CTO PCI is an established technique, but predictors of success remain poorly understood. Methods: A multivariable logistic regression model was used to analyze potentially important demographic, clinical, anatomical, and technical aspects of retrograde CTO PCI cases uploaded to the multicenter European CTO (ERCTO) Club Registry. Results: In calendar years 2018 and 2019, 2,364 retrograde CTO PCI cases constituted the primary analysis cohort. A primary retrograde strategy was used in 1,953…

(1) Background: This cross-sectional study aims to compare a new and non-invasive approach using hyperspectral imaging (HSI) with the conventional modified Allen’s test (MAT) for the assessment of collateral perfusion prior to radial forearm free flap harvest in healthy adults. (2) HSI of the right hand of 114 patients was recorded. Here, three recordings were carried out: (I) basic status (perfusion), (II) after occlusion of ulnar and radial artery (occlusion) and (III) after releasing the ulnar artery (reperfusion). At all recordings, tissue oxygenation/superficial perfusion (StO2 (0–100%); 0–1 mm depth), tissue hemoglobin index (THI (0–100)) and near infrared perfusion index/deep perfusi…

When Fiscal Consolidation Meets Private Deleveraging

2016

We analyze the interaction between fiscal consolidation and private-sector deleveraging in an economy within a monetary union. Pre-existing long term collateralized private debt – a core ingredient of the deleveraging process – plays a critical role in shaping fiscal multipliers. By buffering the short-run fall in debtors’ spending capacity, long-run private debt reduces the short-run multipliers of aggressive (large and/or fast) consolidations. However, absent credibility concerns, aggressive consolidations raise the intensity and length of private deleveraging, causing higher output losses over the medium run. In terms of discounted output losses and welfare, this latter effect dominates,…

Very Early Presentation of Extrahepatic Portal Vein Obstruction Causing Portal Hypertension in an Infant: Uncertainties in the Management and Therape…

2016

Extrahepatic portal vein obstruction, although rare in children, is a significant cause of portal hypertension (PHT) leading to life-threatening gastrointestinal bleeding in the pediatric age group. PHT may also lead to other complications such as hyperesplenism, cholangyopathy, ascites, and even hepatopulmonary syndrome and portopulmonary hypertension that may require organ transplantation. Herein we report the case of an asymptomatic 11-month-old infant wherein a hepatomegaly and cavernous transformation of the portal vein was detected by liver ultrasound. Neither signs of thrombosis in arteriovenous system, nor affectation of biliary tract were identified in the magnetic resonance imagin…

Ultrasound-guided percutaneous treatment of calcific bursitis of the medial collateral ligament of the knee

2021

Calcific bursitis of the medial collateral ligament of the knee is an infrequent pathological condition. In 1988, Kerlan and Glousman identified the clinical features of medial collateral ligament bursitis. Pain and knee functions limitation are the clinical symptoms that are most frequently encountered during the reactive inflammatory process in the bursa, that characterizes the reabsorption phases of the calcific material. It is well documented in the literature that the maximum efficacy of ultrasound-guided percutaneous treatment, with significant reduction or disappearance of symptoms, occurs precisely in this phase. The case report presented in this study confirms the validity as a the…

Kardio-MRT

2004

Since initial reports in the early 1990s cardiac magnetic resonance imaging (CMR) has matured and is likely to become an established method for routine cardiac diagnostics. The development of faster gradient-echo sequences and stronger magnetic fields has led to improved temporal and spatial resolution. Myocardial viability can be examined by morphological and functional analysis. Contrast enhanced MRI (ceMRI), perfusion measurements and regional wall motion analysis are the major diagnostic tools. The ability to image in arbitrary double oblique planes provides comprehensive visualization of the heart. The introduction of the MR navigator technique allowed for free-breathing motion correct…
