Hand strengthening exercises in chronic stroke patients:Dose-response evaluation using electromyography
2016
Abstract Study Design Cross-sectional. Purpose of the Study This study evaluates finger flexion and extension strengthening exercises using elastic resistance in chronic stroke patients. Methods Eighteen stroke patients (mean age: 56.8 ± 7.6 years) with hemiparesis performed 3 consecutive repetitions of finger flexion and extension, using 3 different elastic resistance levels (easy, moderate, and hard). Surface electromyography was recorded from the flexor digitorum superficialis (FDS) and extensor digitorum (ED) muscles and normalized to the maximal electromyography of the non-paretic arm. Results Maximal grip strength was 39.2 (standard deviation: 12.5) and 7.8 kg (standard deviation: 9.4…

2010
Holviala, J, Hakkinen, A, Karavirta, L, Nyman, K, Izquierdo, M, Gorostiaga, EM, Avela, J, Korhonen, J, Knuutila, V-P, Kraemer, WJ, and Hakkinen, K. Effects of combined strength and endurance training on treadmill load carrying walking performance in aging men. J Strength Cond Res 24(6): 1584-1595, 2010—The present study examined the effects of twice weekly total body strength training (ST), endurance cycling (ET), and combined ST and ET (2 + 2 times a week) (SET) training on the load carrying walking test performance on the treadmill (TM) and changes in neuromuscular and endurance performance during a 21-week training period in aging men. Forty healthy men (54.8 6 8.0 years) were divided in…
Bipedicled DIEAP flaps for reconstruction of limb soft tissue defects in male patients.
2016
Summary Background Extensive soft tissue deficiencies involving the limbs can be difficult to reconstruct and may require more than one microsurgical flap transfer to cover the defect. This can be particularly challenging in male patients, where the sacrifice of a donor muscle could result in considerable comorbidity. This paper describes the use of the bipedicled deep inferior epigastric artery perforator (DIEAP) flap to perform a one-stage reconstruction of extensive soft tissue defects in male patients. Methods By using preoperative multidetector computed tomographic (MDCT) angiography, the dominant perforators of the abdominal wall were identified and the bipedicled DIEAP flap was used …
Ca2+-activated K+ channels mediate relaxation of forearm veins in chronic renal failure
2003
In arteries, agonists such as acetylcholine release an endothelium-derived hyperpolarizing factor (EDHF) that is neither nitric oxide nor prostacyclin.To examine the responses to acetylcholine in segments of forearm veins from patients with chronic renal failure who either had never received dialysis or had undergone long-term dialysis, and to determine the contribution of nitric oxide and EDHF to endothelium-dependent relaxation in veins from patients with chronic renal failure.Isometric tension was recorded in rings of forearm vein from 34 non-dialysed patients, 27 dialysed patients and 14 multiorgan donors (controls).Relaxation in response to acetylcholine was reduced in veins of non-dia…
Free Bipedicled Radial Forearm and Posterior Interosseous Artery Perforator Flap Phalloplasty
2019
Abstract Introduction The free radial forearm (FRFA) flap is universally still considered as the gold standard technique in penile reconstruction. Typically, a considerably large flap is required, often involving almost the entire circumference of the forearm. Partial necrosis may occur at the distal-most (dorsoradial) part of the flap as a result of insufficient perfusion. Aim To describe a new technique using the posterior interosseous artery (PIOA) to supercharge FRFA phalloplasty. Methods In a 12-month period, all patients having FRFA flap phalloplasty were enrolled. Perioperative, after complete flap dissection, an indocyanine green perfusion scan was performed. In case of insufficient…
Delayed-type hypersensitivity in classic Kaposi sarcoma patients and controls
2011
Background: Immune perturbation likely affects the development of Kaposi sarcoma (KS) among people infected with the KS-associated herpesvirus (KSHV). We tested whether KSHV-seropositive individuals or cases of classic KS (cKS), which typically originates in the leg, had differing delayed-type hypersensitivity (DTH) in the forearm or leg. Methods: Mantoux DTH with three antigens (Candida, tetanus, PPD) was performed on the forearm and leg of 15 cKS cases, 14 KSHV-positives without KS, and 15 KSHV-negative controls. The diameters of induration responses were compared by group and body site. Results: Leg DTH was greater than forearm DTH among controls (mean difference 5.6 mm, P=0.0004), where…
The incidence of hip, forearm, humeral, ankle, and vertebral fragility fractures in Italy: results from a 3-year multicenter study
2010
Introduction: We aimed to assess the incidence and hospitalization rate of hip and "minor" fragility fractures in the Italian population.Methods: We carried out a 3-year survey at 10 major Italian emergency departments to evaluate the hospitalization rate of hip, forearm, humeral, ankle, and vertebral fragility fractures in people 45 years or older between 2004 and 2006, both men and women. These data were compared with those recorded in the national hospitalizations database (SDO) to assess the overall incidence of fragility fractures occurring at hip and other sites, including also those events not resulting in hospital admissions.Results: We observed 29,017 fractures across 3 years, with…
Comparison between local and regional anesthesia in arteriovenous fistula creation.
2011
Purpose Assessment of the effectiveness of Brachial Plexus Block (BPB) via axillary approach compared to regional anesthesia for arteriovenous fistula surgery in patients affected by end-stage renal disease. Methods We compared forty patients randomly divided into two groups. Group A underwent BPB procedure with 15 mL ropivacaine 1% and 10 mL of saline (0.9% NaCl) via axillary approach. Group B received local anesthesia with lidocaine 2%. The forearm blood vessels were assessed by Doppler ultrasonography before and after the intervention. Results BPB performed on Group A was associated with a considerable venous dilation and a significant decrease (48.7%, P<.05) in pulsatility index (PI)…
Contractile hyporesponsiveness to norepinephrine of forearm veins in chronic renal failure.
2006
Background We recently reported that endothelium-dependent relaxation is impaired in forearm veins from patients with chronic renal failure. However, assessment of responses to norepinephrine remains controversial. We examined the contractile response to norepinephrine in forearm veins from patients on chronic hemodialysis and the role of nitric oxide (NO), prostanoids, and Ca 2+ -activated K + channels in this response. Methods Isometric contraction curves were obtained in rings of forearm vein from 21 dialyzed patients and 12 multiorgan donors in response to norepinephrine (1 nmol/L to 10 μmol/L) or KCl (5 to 100 mmol/L). Results Veins from uremic patients were markedly less responsive to…
Functional assessment: Free thin anterolateral thigh flap versus free radial forearm reconstruction for hemiglossectomy defects
2015
Background To compare free thin anterolateral thigh (ALT) flap with free radial forearm (FRF) flap in the reconstruction of hemiglossectomy defects, and to introduce our methods and experience in the tongue reconstruction with free thin ALT flap. Material and Methods The clinicopathologic data of 46 tongue carcinoma cases hospitalized from December 2009 to April 2014 were obtained from Nangjing Stomatological Hospital, Medical School of Nanjing University. All the subjects were evaluated for the articulation and the swallowing function 3 months after the surgery. Results Among these 46 patients, 12 patients underwent tongue reconstruction after hemiglossectomy with ALT flap; 34 patients und…
