Versatility of the Free Anterolateral Thigh Flap in the Reconstruction of Large Defects of the Weight-Bearing Foot: A Single-Center Experience with 2…
2016
Background Reconstruction of the weight-bearing surface of the foot represents a challenging task. With very little scope to borrow glabrous tissue from adjacent areas means that achieving a “like for like” reconstruction is rarely possible. In this setting, alternative approaches need to be considered. In this article we present our experience with various differing designs of the anterolateral thigh flap (ALT) in the reconstruction of 20 large defects of the weight-bearing sole. Methods Twenty patients with complex soft tissue defects of the weight-bearing sole underwent reconstruction over a 5-year period. Five cases were complicated by osteomyelitis resulting in significant calcaneal …
Asymmetry of gait after free flap reconstruction of severe tibial fractures with extensive soft-tissue damage.
2000
Gait patterns of the preferred speed were investigated on 17 patients recovering (9 months-14 years) after reconstruction of severe tibial fractures. A novel data-acquisition system was used to record the plantar pressures as well as electromyographic (EMG) activities during walking. The results indicated incomplete recovery of symmetrical gait patterns. In particular, the duration of the stance phase was shorter on the operated side (mean (SD) 701 (90) ms compared with 765 (128) ms, p < 0.001). The peak pressure points under the foot were different on bilateral comparison, the operated side being regularly higher under the lateral forefoot area. This may imply attempts to reduce the loadin…
Spanish Version of the Knowledge and Attitudes Survey Regarding Pain.
2019
A variety of valid tools are available to assess staff knowledge and attitudes regarding pain, among which is the Knowledge and Attitudes Survey Regarding Pain. Although this instrument has been widely and successfully used, a valid and adapted Spanish version is yet to be developed. The purpose of this study was to validate the Spanish version of the Knowledge and Attitudes Survey Regarding Pain. After translating and back-translating this tool, we conducted a cross-cultural adaptation and construct validation with 102 participants, including nursing professionals (in palliative care, oncology, and intensive care) from five health centers and final-year nursing students. All participants w…
Detection of coronary artery calcifications predicting coronary heart disease: comparison of fluoroscopy and spiral CT.
1998
The aim of this study was to evaluate the clinical relevance of coronary artery calcifications detected by spiral CT, congruence with fluoroscopy (FS) and coronary angiography, and comparison with studies reporting on application of double-helical CT and ultrafast CT. Forty patients underwent spiral CT (2-mm slice thickness, table feed 3 mm/s), coronary angiography, and FS (performed in the usual manner). Stenosis and calcifications were evaluated semiquantitatively. Nineteen patients suffering from a stenosis ≥ 75 % were verified at coronary angiography. All had coronary artery calcification on spiral CT. Fluoroscopy did not detect 8 of 19 patients with a stenosis ≥ 75 % (1 vessel: n = 1; …
Plasma endothelin-1 levels in patients with angina pectoris and normal coronary angiograms.
1998
Some patients with typical angina and electrocardiographic evidence of ischemia have normal coronary angiograms. These patients have a reduced coronary flow reserve and abnormal endothelium-dependent vasodilator responses; this syndrome is known as microvascular angina. Among endothelium-derived peptides, endothelin-1 (ET-1) is a potent vasoconstrictor and an important modulator of microvascular function.Plasma ET-1 was measured in 13 patients with typical angina, instrumental evidence of ischemia, and normal arteriograms and in 20 normal control subjects.Mean concentration of ET-1 was 2.89+/-1.24 pmol/L in patients with angina and normal angiograms and 1.99+/-0.81 pmol/L in normal control …
Neuromuscular fatigue following constant versus variable-intensity endurance cycling in triathletes
2008
International audience; The aim of this study was to determine whether variable power cycling produced greater neuromuscular fatigue of knee extensor muscles than constant power cycling at the same mean power output. Eight male triathletes (age : 33 ± 5 yr, mass : 74 ± 4 kg, OV&2max : 62 ± 5 ml.kg-1.min-1, maximal aerobic power : 392 ± 17 W) performed two 30 min trials on a cycle ergometer in a random order. Cycling exercise was performed either at a constant power output (CP) corresponding to 75% of the maximal aerobic power (MAP) or a variable power output (VP) with alternating ± 15%, ± 5%, and ± 10% of 75% MAP approximately every 5 min. Maximal voluntary contraction (MVC) torque, maximal…
Is ERCP manometry useful in the choice of treatment of stones of the common bile duct?
1988
To verify the appropriateness of sphincterotomy as the treatment of choice of choledocholithiasis, since 1980 we have been using endoscopic retrograde cholangiopancreatographic (ERCP) manometry of the sphincter of Oddi (SO). This method allows direct investigation of SO motor activity and provides useful information regarding the presence of benign papillary stenosis (BPS). Thirty-four patients were investigated because the radiological examination indicated BPS might be present. Of these, 20 had common bile duct (CBD) stones, while the remaining 14 presented with biliarylike pain and one or more of the following: CBD dilation (larger than 12 mm); emptying of the ERCP contrast medium took l…
Emergency toe-to-hand transfer for post-traumatic finger reconstruction: A multicenter case series
2019
Abstract Background The aim of this paper was to evaluate the outcomes of a homogenous series of emergency with a toe-to-hand transfer reconstructions with a different timing: immediate (same surgical step with the debridement), primary (in the first 24 h), early (24–72 h after the debridement) or delayed (72 h-7 days). Materials and methods Between 2001 and 2011, 31 patients received an immediate reconstruction with a toe-to-hand transfer. Data on indications, timing, type of surgery, complications and outcomes (sensory and motor recovery, patient satisfaction) were extrapolated and recorded. Results Most of the procedures in our series (71%) were performed in the first 24 h. Survival rate…
Validity and reliability of the Migraine-Treatment Optimization Questionnaire.
2009
Our aim was to establish the validity and reliability of a patient-rated Migraine Treatment Optimization Questionnaire (M-TOQ in primary care. Patients who met International Classification of Headache Disorders, 2nd edn criteria for migraine completed a 19-item questionnaire containing candidate items for the M-TOQ and three questionnaires designed to test convergent/construct validity [Migraine Disability Assessment Scale (MIDAS), Headache Impact Test (HIT)-6 and Migraine-Specific Quality of Life Scale (MSSQoL)]. A 15-item (M-TOQ15) and a five-item (M-TOQ-5) questionnaire were derived. Two hundred and fifty-three adult patients were recruited. Five treatment optimization domains were iden…
Effects of plantar flexor muscle fatigue induced by electromyostimulation on postural coordination
2007
International audience; The aim of the present study was to investigate the influence of a modification of an intrinsic capacity (plantar flexor strength) on the implementation of in-phase and anti-phase mode of coordination. Analysis of hip and ankle relative phases during fore-aft tracking task was done before and after an electromyostimulation fatigue protocol on the soleus muscles. Results showed participants used exclusively in-phase and anti-phase modes of coordination, with a sudden switch from one to the other with target frequency increase. Regarding tracking tasks, fatigue induces a decrease of performance for lower frequencies, and a significant decrease of switch frequency (−0.0…
