RESUMO

In order to solve the saturation distortion phenomenon of R component in fingertip video image, this paper proposes an iterative threshold segmentation algorithm, which adaptively generates the region to be detected for the R component, and extracts the human pulse signal by calculating the gray mean value of the region to be detected. The original pulse signal has baseline drift and high frequency noise. Combining with the characteristics of pulse signal, a zero phase digital filter is designed to filter out noise interference. Fingertip video images are collected on different smartphones, and the region to be detected is extracted by the algorithm proposed in this paper. Considering that the fingertip's pressure will be different during each measurement, this paper makes a comparative analysis of pulse signals extracted under different pressures. In order to verify the accuracy of the algorithm proposed in this paper in heart rate detection, a comparative experiment of heart rate detection was conducted. The results show that the algorithm proposed in this paper can accurately extract human heart rate information and has certain portability, which provides certain theoretical help for further development of physiological monitoring application on smartphone platform.

RESUMO

PURPOSE: The purpose of this study was to assess the clinical and sonographic features of flexor tendon sheath ganglion cysts in the fingers. METHODS: We retrospectively reviewed the clinical and sonographic features of 35 cases of flexor tendon sheath ganglion cysts in the fingers in 34 patients that were pathologically confirmed between 2003 and 2018. RESULTS: The mean age of the patients was 44.2 years (range, 11-73 years). Lesions were located at the level of the metacarpophalangeal joint (n = 22 [63%]) and proximal phalanx (n = 11 [31%]), and involvement of the third finger was common (n = 19 [54%]). The mean lesion size was 6 mm and the mean volume was 90 mm3 . None of the lesions had a pedicle. Lesions were homogeneous (n = 24 [69%]) and anechoic (n = 23 [66%]). A septum was noted in 12 cases (34%). CONCLUSIONS: Flexor tendon sheath ganglion cysts are most commonly located in the third finger and at the level of the metacarpophalangeal joint and proximal phalanx. It usually presents as a simple cyst without a pedicle, but occasionally exhibits a mixed echogenicity and contains a septum.

RESUMO

OBJECTIVE. The purpose of this article is to review the general guidelines for MRI of the finger and emphasize normal finger anatomy as it relates to abnormalities and injuries. CONCLUSION. Advanced imaging, particularly MRI, is increasingly relied on to make the diagnosis and guide management of finger injuries. It is incumbent on radiologists to understand the complex anatomy of the fingers as well as to be familiar with common injuries and aspects of injuries that affect management in order to meaningfully contribute to patient care.

RESUMO

A 51-year-old man underwent second-line treatment for non-small-cell lung cancer (NSCLC) with the immune checkpoint inhibitor (ICI) pembrolizumab. On day 2 after two cycles of pembrolizumab, he presented with edema limited to the left third, fourth, and fifth fingers. Based on symptoms, laboratory results, and contrast-enhanced magnetic resonance imaging (MRI) findings, we diagnosed him with tenosynovitis. We prescribed oral prednisolone (0.5 mg/kg/day), and pembrolizumab was continued. Prednisolone immediately relieved the symptoms, and the tumor was still shrinking on day 21 after eight cycles of pembrolizumab. ICI-induced tenosynovitis was managed while continuing ICI usage, suggesting that 0.5 mg/kg/day prednisone might be effective for tenosynovitis without ICI cessation.

RESUMO

Neurotechnology attempts to develop supernumerary limbs, but can the human brain deal with the complexity to control an extra limb and yield advantages from it? Here, we analyzed the neuromechanics and manipulation abilities of two polydactyly subjects who each possess six fingers on their hands. Anatomical MRI of the supernumerary finger (SF) revealed that it is actuated by extra muscles and nerves, and fMRI identified a distinct cortical representation of the SF. In both subjects, the SF was able to move independently from the other fingers. Polydactyly subjects were able to coordinate the SF with their other fingers for more complex movements than five fingered subjects, and so carry out with only one hand tasks normally requiring two hands. These results demonstrate that a body with significantly more degrees-of-freedom can be controlled by the human nervous system without causing motor deficits or impairments and can instead provide superior manipulation abilities.

RESUMO

The defectiveness of the fat suppression becomes the factor of the decrease of the quality of the diagnosis of magnetic resonance imaging. It is reported that the use of magnetic field uniformity adjuvant pad is effective for reduce poor fat suppression. The ball bullets, polystyrene balls, and polished rice are used for pad packing material, in recently, it was reported that fat suppression effect was good by the use of the small glass beads. Therefore, we tested the utility of small glass beads pad in the neck and fingers in this study. Neck and the fingers of subjects were imaged with T1-weighted image with fat suppression and T1-high resolution isotropic volume excitation image. The fat suppression effect of each image was compared with the polished rice and glass beads as material of pad used by physical, observation, and contact evaluation. In the result, satisfactory results were obtained by using glass beads, and it is suggested that fat suppression effect is improved by using glass beads as a filling material of pad in clinical study as a conclusion.

RESUMO

OBJECTIVE: Injuries of the flexor-tendon-pulley system are common in rock climbers. The status of the A3 pulley ligament is crucial for grading such injuries. As standard MRI may miss lesions of the A3 pulley ligament, we introduce a semi-dynamic MRI sequence. MATERIALS AND METHODS: Twenty-two fingers (14 volunteers, 3 injured climbers) were scanned using a sagittal T1 turbo spin echo sequence (repetition time: 400 ms, echo time: 14 ms, slice thickness: 5 mm) in six consecutive finger positions from stretched to maximum possible flexion. RESULTS: No pulley lesion was found in volunteers. Bowstringing was detected in 3 injured fingers including the A3 pulley. CONCLUSION: Semi-dynamic MRI is an technique that is easy to perform to identify injuries of the A3 pulley ligament that were not seen on standard imaging.

RESUMO

A 64-year-old man had spasticity of digits 3 and 4 of the right hand for 22 years following a stroke. Activities of daily living (ADL) were impaired due to the disuse of the right arm. The flexor digitorum superficialis and flexor digitorum profundus muscles of digits 3 and 4 of the patient's right forearm were identified using ultrasound guidance, and botulinum toxin type A was selectively injected into those sites. Furthermore, following the injections, occupational therapy was performed for the right arm and fingers, and spasticity was assessed after 2 weeks and at 1, 2, 3, 4, and 5 months. The patient showed improvement in all the evaluations (the Modified Ashworth Scale, Disability Assessment Scale, functional independence measure, active range of motion angle, and movement of holding a cup), and function was maintained throughout the evaluation period. Performing botulinum toxin type A injection under ultrasound guidance to selectively identify the flexor digitorum superficialis and flexor digitorum profundus muscles involved in finger spasticity helped restore finger functioning and improve ADL.

RESUMO

BACKGROUND: The usability of dexterous hand prostheses is still hampered by the lack of natural and effective control strategies. A decoding strategy based on the processing of descending efferent neural signals recorded using peripheral neural interfaces could be a solution to such limitation. Unfortunately, this choice is still restrained by the reduced knowledge of the dynamics of human efferent signals recorded from the nerves and associated to hand movements. FINDINGS: To address this issue, in this work we acquired neural efferent activities from healthy subjects performing hand-related tasks using ultrasound-guided microneurography, a minimally invasive technique, which employs needles, inserted percutaneously, to record from nerve fibers. These signals allowed us to identify neural features correlated with force and velocity of finger movements that were used to decode motor intentions. We developed computational models, which confirmed the potential translatability of these results showing how these neural features hold in absence of feedback and when implantable intrafascicular recording, rather than microneurography, is performed. CONCLUSIONS: Our results are a proof of principle that microneurography could be used as a useful tool to assist the development of more effective hand prostheses.

RESUMO

PURPOSE: Rupture of the flexor pollicis longus (FPL) and index flexor digitorum profundus (FDP2) tendons often occurs after locking plate fixation for distal radius fracture. This study aimed to determine the shortest tendon-radius distances of different hand positions. METHODS: Fifty-nine hands of 30 healthy volunteers were studied. Distances between the FPL or FDP2 and distal radius were calculated in six wrist positions: 30° palmar flexion, neutral, 30° dorsiflexion, 60° dorsiflexion, maximum dorsiflexion, and 40° ulnar deviation with three finger positions (full extension and flexion of fingers, full flexion of the thumb or index finger, and full extension of the other four fingers). The shortest distance between the FPL or FDP2 and distal radius was noted. RESULTS: The shortest distance between the FPL and distal radius was during maximum wrist dorsiflexion with isolated thumb flexion. The distance between the FDP2 and distal radius was shortest with all-finger flexion in 30° wrist dorsiflexion. CONCLUSIONS: It is necessary to measure the distance between the FPL and distal radius in maximal wrist dorsiflexion with full flexion of the isolated thumb, as the shortest distance was observed with flexion of the isolated thumb. On the contrary, we recommend measuring the distance between the FDP2 and distal radius in 30° wrist dorsiflexion with flexion of all fingers.

RESUMO

Spondyloarthritis may be increasingly present in older patients as life expectancy increases. We investigated clinical differences between early-onset and late-onset spondyloarthritis in Japan.We retrospectively reviewed 114 patients consecutively diagnosed with spondyloarthritis. The clinical course of each patient was observed for ≥1 year. We defined early-onset and late-onset spondyloarthritis as <57 or ≥57 years at a median age of this study group, respectively. We compared clinical characteristics between these 2 groups.Disease duration was significantly shorter before diagnosis in the late-onset group (P < .01). Inflammatory back pain (IBP) was significantly more common in the early-onset group (P < .01), whereas dactylitis frequency was significantly higher in the late-onset group. Significantly more patients with early-onset spondyloarthritis were human leukocyte antigen (HLA) B27-positive (P < .01). Articular synovitis, particularly of the wrist, was significantly more common on power Doppler ultrasound (PDUS) in the late-onset group (P < .01). Tenosynovitis or peritendinitis, particularly in the finger and wrist flexors were also more frequent in the late-onset group (P < .001 and P < .05, respectively). Enthesitis of the finger collateral ligament and lateral collateral ligament were significantly more common in the late-onset group (both P < .05). Multiple logistic regression analysis revealed that, comparatively, IBP was significantly and independently much more likely to occur in the early-onset group.The patients with late-onset spondyloarthritis had a lower frequency of IBP and HLA B27 and a higher frequency of dactylitis and PDUS findings in peripheral involvement.

RESUMO

With aging, hand mobility and manual dexterity decline, even under healthy circumstances. To assess how aging affects finger movement control, we compared elderly and young subjects with respect to (1) finger movement independence, (2) neural control of extrinsic finger muscles and (3) finger tendon displacements during single finger flexion. In twelve healthy older (age 68-84) and nine young (age 22-29) subjects, finger kinematics were measured to assess finger movement enslaving and the range of independent finger movement. Muscle activation was assessed using a multi-channel electrode grid placed over the flexor digitorum superficialis (FDS) and the extensor digitorum (ED). FDS tendon displacements of the index, middle and ring fingers were measured using ultrasound. In older subjects compared to the younger subjects, we found: (1) increased enslaving of the middle finger during index finger flexion (young: 25.6 ± 12.4%, elderly: 47.0 ± 25.1%; p = 0.018), (2) a lower range of independent movement of the index finger (youngmiddle = 74.0%, elderlymiddle: 45.9%; p < 0.001), (3) a more evenly distributed muscle activation pattern over the finger-specific FDS and ED muscle regions and (4) a lower slope at the beginning of the finger movement to tendon displacement relationship, presenting a distinct period with little to no tendon displacement. Our study indicates that primarily the movement independence of the index finger is affected by aging. This can partly be attributed to a muscle activation pattern that is more evenly distributed over the finger-specific FDS and ED muscle regions in the elderly.

RESUMO

OBJECTIVE: To determine whether novel multi-energy spectral photon-counting computed tomography (SPCCT) imaging can detect and differentiate between monosodium urate (MSU), calcium pyrophosphate (CPP), and hydroxyapatite (HA) crystal deposits ex vivo. METHODS: A finger with a subcutaneous gouty tophus and a calcified knee meniscus excised at the time of surgery were obtained. The finger was imaged using plain x-ray, dual-energy CT (DECT), and multi-energy SPCCT. Plain x-ray and multi-energy SPCCT images of the meniscus were acquired. For validation purposes, samples of the crystals were obtained from the tophus and meniscus, and examined by polarized light microscopy and/or x-ray diffraction. As further validation, synthetic crystal suspensions of MSU, CPP, and HA were scanned using multi-energy SPCCT. RESULTS: Plain x-ray of the gouty finger revealed bone erosions with overhanging edges. DECT and multi-energy SPCCT both showed MSU crystal deposits; SPCCT was able to show finer detail. Plain x-ray of the calcified meniscus showed chondrocalcinosis consistent with CPP, while SPCCT showed and differentiated CPP and HA. CONCLUSION: Multi-energy SPCCT can not only detect, differentiate, and quantify MSU crystal deposits in a gouty finger ex vivo, but also specifically detect, identify, and quantify CPP within an osteoarthritic meniscus, and distinguish them from HA crystal deposits. There is potential for multi-energy SPCCT to become useful in the diagnosis of crystal arthropathies.

RESUMO

OBJECTIVES: The condition known as 'Mechanic's Hands' is a thickened, hyperkeratotic eruption, which is bilaterally symmetric along the fingers, and often occurs in patients with some connective tissue diseases. Nail fold capillaroscopy is a non-invasive technique for evaluation of connective tissue diseases. We evaluated the prevalence of mechanic hands in patients with connective tissue diseases and compared the clinical manifestations and capillaroscopic changes in the patients with and without mechanic hands. METHODS: The clinical manifestations and capillaroscopy of 576 patients with scleroderma, dermatomyositis, systemic lupus erythematosus, Sjogren's syndrome, undifferentiated and mixed connective tissue diseases were evaluated and compared in patients with and without mechanic hands. RESULTS: A total of 576 patients were enrolled. Mechanic hands were observed in 17.2% of patients: 50% of mixed connective tissue disease, 35% of dermatomyositis, 15.4% of scleroderma, 14.9% of undifferentiated connective tissue disease, 14.3% of Sjogren's syndrome, and no patient with SLE. Among them, 80.8% had abnormal capillaroscopic findings. In dermatomyositis patients, Raynaud's phenomenon, anti-Jo-1 positivity, and some capillaroscopy findings were detected more frequently in patients with mechanic hand. In scleroderma, positive Scl70 and capillary loss were observed more frequently in patients without mechanic hands. CONCLUSIONS: Mechanic hands can be a presenting sign of some systemic connective tissue diseases. Probably, finding this sign on examination, especially together with Raynaud's phenomenon or abnormal capillaroscopy, can be helpful in the early diagnosis of the connective tissue diseases and can be used as a predictive and prognostic tool in future studies.

RESUMO

INTRODUCTION AND OBJECTIVES: The nail unit is a subject of interest in several diseases, often involving different medical fields. Even if few data are available for psoriasis and psoriatic arthritis, no data regarding ultrasonography and imaging are present for other degenerative and inflammatory conditions. The aim of this study was to explore through imaging the changes of nail and enthesis in inflammatory and degenerative conditions in order to find qualitative and quantitative changes related to distal interphalangeal joints. METHODS: The study sample was composed of 51 patients affected by psoriatic arthritis, 31 affected by psoriasis, 37 subjects with rheumatoid arthritis, 34 with osteoarthritis and 50 healthy controls for a total of 203 individuals. Ultrasonography of the nails was performed after clinical evaluation in a cross-sectional study design by blinded ultrasonographers who were blind to patient data. Data about power Doppler signal of the nail bed, tendon entheses, thickness of nail plate and nail bed were recorded. RESULTS: Patients affected by psoriasis and psoriatic arthritis differ from other subgroups, and power Doppler signal at the enthesis seems to be an exclusive feature of psoriatic arthritis (Pearson's chi-square of 5297 and p < 0.001 with adjusted residuals). Nail plate thickness also differs in psoriasis and psoriatic arthritis, but surprisingly in osteoarthritis, too, with similar results. CONCLUSIONS: This study provides qualitative and quantitative data regarding the ultrasonographic features of nails in several rheumatic diseases with a potential role of ultrasonography in characterising them.
