Pain-induced alterations in the individual non-esterified fatty acids in serum.
1979
Changes of individual non-esterified fatty acids in serum were studied in 7 metabolically healthy patients, suffering from idiopathic trigeminal neuralgia, who underwent electrocoagulation of gasserian ganglion under neurolepthypalgesia. The mean concentration of fatty acids increased by about 40% during the strong surgical pain stimulus. The increased lipolysis affected all individual fatty acids in proportion to the ratio of their presence in adipose tissue. The mechanism of pain-induced activation of lipase and possible consequences of alterations in individual non-esterified fatty acids are discussed.
Water Jet Dissection in Neurosurgery: An Update After 208 Procedures With Special Reference to Surgical Technique and Complications
2010
Background Water jet dissection represents a promising technique for precise brain tissue dissection with preservation of blood vessels. In the past, the water jet dissector has been used for various pathologies. A detailed report of the surgical technique is lacking. Objective The authors present their results after 208 procedures with a special focus on surgical technique, intraoperative suitability, advantages, and disadvantages. Methods Between March 1997 and April 2009, 208 patients with various intracranial neurosurgical pathologies were operated on with the water jet dissector. Handling of the device and its usefulness and extent of application were assessed. The pressures encountere…
Neuromuscular Differences Between Endurance-Trained, Power-Trained, and Sedentary Subjects
2003
This study tested the hypothesis that neuromuscular characteristics of plantar flexor (PF) and knee extensor (KE) muscles explain differences of both performance in vertical jump and maximal voluntary isometric contraction (MVC) between endurance-trained (END, n = 9), power-trained (POW, n = 8), and sedentary subjects (SED, n = 8). Evoked twitch characteristics of PF and KE were measured. MVC, maximal voluntary activation (%VA) of KE, and performance in vertical jump were also measured. POW have higher maximal rate of twitch force development (MRFD) than SED and END for both PF (p < 0.05) and KE (p < 0.01); %VA and MVC were higher for POW and END than SED (p < 0.01). Higher performances wer…
Cutaneous, genital and oral lichen planus: a descriptive study of 274 patients
2018
Background Lichen planus (LP) is a chronic autoimmune disease that affects the oral mucosa as well as the skin, genital mucosa and other sites. Objective: to evaluate the correlation between oral, genital and cutaneous lichen planus, in a sample of LP patients. Material and Methods This descriptive study reviewed 274 clinical histories of patients, who all presented histological confirmation of lichen planus verified by a pathologist, attending research centers in Barcelona. Results A total of 40 LP patients (14.59%) presented genital lesions. Of 131 patients with cutaneous LP (47.8%), the most commonly affected zones were the body’s flexor surfaces, representing 60.1% of cases. 24% of pati…
Hereditary Angioedema: Long-Term Treatment with One or More Injections of C1 Inhibitor Concentrate per Week
2009
<i>Background:</i> Hereditary angioedema due to C1 inhibitor deficiency (HAE-C1-INH) is characterized by recurrent edema attacks in various organs. The objective of the present study was to assess the efficacy and safety of weekly long-term replacement treatment with one or more injections of plasma-derived C1-INH concentrate per week (WLTC) in patients with HAE-C1-INH. <i>Methods:</i> Nineteen patients with HAE-C1-INH underwent WLTC for 9 years on average. The benefits and risks were determined based on regular recording by the patients of the severity and number of attacks at the beginning and the end of the study. <i>Results:</i> All patients reported …
Magnetic resonance and ultrasound in achilles tendinopathy: Predictive role and response assessment to platelet-rich plasma and adipose-derived strom…
2017
To assess the correlation between magnetic resonance and ultrasound findings and clinical outcome after intratendinous injection of leucocyte-rich platelet-rich plasma or adipose-derived stromal vascular fraction in patients with non-insertional Achilles tendinopathy.Forty-three patients (age: 47.8±5.1, range 29-55) with unilateral or bilateral non-insertional Achilles tendinopathy (58 tendons overall) were randomly assigned to platelet-rich plasma (22 patients, 28 tendons) or adipose-derived stromal vascular fraction (21 patients, 30 tendons) injection group. All patients underwent magnetic resonance (tendon cross-sectional area, signal intensity, maximum anteroposterior thickness were mea…
Medium chain acylcarnitines dominate the metabolite pattern in humans under moderate intensity exercise and support lipid oxidation.
2010
BACKGROUND: Exercise is an extreme physiological challenge for skeletal muscle energy metabolism and has notable health benefits. We aimed to identify and characterize metabolites, which are components of the regulatory network mediating the beneficial metabolic adaptation to exercise. METHODOLOGY AND PRINCIPAL FINDINGS: First, we investigated plasma from healthy human subjects who completed two independent running studies under moderate, predominantly aerobic conditions. Samples obtained prior to and immediately after running and then 3 and 24 h into the recovery phase were analyzed by a non-targeted (NT-) metabolomics approach applying liquid chromatography-qTOF-mass spectrometry. Under t…
Adhesive Small Bowel Obstruction: Predictive Factors of Lack of Response in Conservative Management with Gastrografin
2015
<b><i>Background:</i></b> Gastrografin represents a useful tool in the diagnosis and management of adhesive small bowel obstruction (ASBO). The aim of this study is to identify variables with negative influence in nonoperative management with gastrografin. <b><i>Methods:</i></b> From August 2008 to March 2013, 223 consecutive patients with 235 episodes of ASBO were included and received gastrografin. A protocol for prospective data collection was developed. In order to explore factors related to the failure of nonoperative treatment, univariate and multivariate analysis were performed. <b><i>Results:</i></b> One hundred…
A comparative study of naproxen gel and flufenamic acid gel in the treatment of soft tissue injuries.
1990
One hundred patients were enrolled in a single-blind, randomized, parallel group study to compare naproxen gel (10%) with flufenamic acid gel (3%) for the treatment of soft tissue injuries. Demographic variables, the distribution of diagnoses (tendinitis, bursitis/synovitis, synovitis, periarthritis, epicondylitis) and initial severity of the complaint were similar between the two groups. The gels were applied 2 to 6 times per day, as required, and conventional clinical indices were evaluated at Day 1 (on entry to the study), Day 3 and Day 7. Global assessments of efficacy were made by both physicians and patients at the end of the study. By Day 7 both treatments had produced a highly signi…
A prospective clinical study of polycarboxylate cement in periapical surgery
2011
Objective: To evaluate the clinical efficacy of polycarboxylate cement as retrograde filling material. Design: A prospective clinical study was made of 25 patients subjected to periapical surgery with ultrasound and magnifying loupes, in which polycarboxylate cement was used as retrograde filling material. Measurements were made of the area and diameter of the lesions pre- and postoperatively, and 6 and 12 months after the operation. The apical resection and retrograde filling areas were also measured, and the prognosis following surgery was recorded. Results: A total of 23 patients with 31 apicoectomized teeth were studied (2 patients being lost to follow-up). The mean area of the periapic…
