Sonographic evaluation of nasal tip skin stickness among patients undergoing rhinoplasty with or without defatting

The Journal of Qazvin University of Medical Sciences, 2012

Background: Skin thickness has an important role in aesthetic results of rhinoplasty. Currently, some surgeons employ defatting technique to reduce subcutaneous tissues and decrease the thickness of skin during rhinoplasty. Objective: The aim of this study was to compare the nasal tip skin thickness with and without nasal tip skin defatting technique and to further evaluate the long term effects of this technique on rhinoplasty patients by sonography. Methods: In a case-control study, 111 rhinoplasty candidates were evaluated at a university referral hospital in northern Iran during January to August 2010. Before operation, all patients were investigated through physical exams. Later, the skin thickness of the tip and supra tip were measured by sonography. Patients with moderate to thick nasal skin were randomly allocated to case and control groups for defatting. Sonography results of 44 patients, obtained one and 12 months after the surgery, were compared with those found in two groups before the surgery using Wilcoxon test and Repeat Measure test. Findings: A total of 111 patients with mean age of 25.1±7.6 years including 16 (14.4%) men and 95 (86.6%) women were enrolled. Based on physical examinations, the skin type was thin in 20 (18.9%), moderate in 68 (59.4%), and thick in 23 cases (21.7%). Considering the sonography results, the skin type was thin in 7 (6.8%), moderate in 83 (80.6%), and thick in 13 cases (12.6%). There was no significant difference in the thickness of tip and supra tip skin between defatted cases and control group measured before surgery and within the follow-up period. Conclusion: Based on results found through this study, Sonography is a precise instrument in assessing the nasal skin thickness before rhinoplasty. Defatting technique was shown to be of no effect on reduction of skin thickness of tip and supra tip in moderate or thick skins following rhinoplasty.

The short-term effects of plantar vibration on balance disorder after stroke

Background: Balance disorders are common in patients following stroke. There are a number of physiotherapy modalities to treat balance impairments, one of which is vibration. The effects of vibration on balance disorders after stroke have not been investigated. This case report demonstrates the short-term effects of plantar vibration on the balance impairment of a patient with stroke. Case presentation: A 72-years-old man with right hemiplegia resulted from stroke was admitted for vibration therapy after not responding to standard rehabilitation interventions. He complained of balance problems despite walking independently. Main studied outcomes were timed up and go test and posturography. Foot sensation, ankle plantar flexor spasticity, and the passive range of ankle dorsiflexion were assessed, as well. Vibration with a frequency of 100 Hz was introduced to the sole of the affected foot for 5 minutes. After intervention, all tests were improved compared to the baselines. Conclusion: This case showed that the vibration was effective for improving balance disorder after stroke.

Sliding mode control of intramuscular functional electrical stimulation using fuzzy neural network with terminal sliding mode learning

2015 7th International IEEE/EMBS Conference on Neural Engineering (NER), 2015

During the last decade, functional neuromuscular stimulation (FNS) has been proposed as a potential technique for restoring motor function in paralyzed limbs. A major challenge to restoring a desired functional limb movement through the use of intramuscular stimulation is the development of a robust control strategy for determining the stimulation patterns. A major impediment to stimulating the paralyzed limbs and determining the stimulation pattern has been the highly non-linear, time-varying properties of electrically stimulated muscle, muscle fatigue, large latency and time constant which limit the utility of pre-specified stimulation pattern and open-loop FES control system. In this paper we present a robust strategy for multi-joint control through intramuscular stimulation in which the system parameters are adapted online and the controller requires no offline training phase. The method is based on the combination of sliding mode control with fuzzy logic and neural control. Extensive experiments on three rats are provided to demonstrate the robustness, stability, and tracking accuracy of the proposed method. The results show that the proposed strategy can provide accurate tracking control with fast convergence.

Effect of low frequency stimulation of perforant path on kindling acquisition and synaptic transmission in the dentate gyrus in rats

Physiology and Pharmacology, 2007

Introduction: Previous studies have shown that low frequency stimulation (LFS) has an inhibitory effect on kindling acquisition. However, the mechanism of this effect has not been completely determined. In the present study, the effect of LFS of the perforant path on seizures induced by rapid perforant path kindling was investigated. Methods: Animals were kindled by electrical stimulation of perforant path. One group of animals (n=6) received LFS (0.1 ms pulses at 1 Hz, 200 pulse, and 50-150 µA) after termination of each kindling stimulations. In control groups, animals received only kindling stimulations (n=8) or LFS (n=4). Basal field potential recording and paired pulse stimulations were done every day, before kindling stimulations. Results: Application of LFS significantly retarded the kindling acquisition and increased the number of stimulations to achieve different seizure stages [F(4,60)=10.9, P<0.0001]. LFS also prevented increment of slope of field excitatory postsynaptic potentials and population spike amplitude during kindling (P<0.001) (There was 88.6±1.7% increment in fEPSP and 94±2.3% increment in PS in kindled group and 3.5±.05% increment in fEPSP and 12.3±0.1% decrease in PS in kindled+LFS group). In addition, LFS significantly prevented the marked increase in early (10-50 ms intervals) and late (300-1000 ms intervals) paired pulse depression induced by kindling (P<0.01). Conclusion: According to obtained results, it may be suggested that LFS of perforant path has a significant antiepileptogenic effect on perforant path kindled seizures through inhibition of synaptic transmission in dentate gyrus. Meanwhile, LFS prevents compensatory increase in the paired pulse depression during kindling acquisition.

Determination of risk factors for lower extremity injury by video analysis during springboard diving

2019

Background: Competitive diving has both a high speed impact and chronic repetitive character. Jumping from the springboard with poor posture or the sheer volume of dives can increase risk of chronic overuse injuries. The purpose of this study was to evaluate the relationship between dynamic lower extremity malalignments and elite divers' approach the 1 m springboard. Methods: Passive or reflective markers were attached to posterior surface of the subjects' bodies. Twelve elite divers performed "Forward Diving Straight" with one of the Traditional (TRD) or Hurdle pre-flight (HPF) approach on the 1m springboard. Their dynamic malalignments of ankle, knee and hip were evaluated during diving performance. The relationship between approach pattern and dynamic malalignment of ankle, knee, and hip in the frontal plane at each step was determined using “Generalized Estimating Equation” (GEE) with the “Identity Function” and the “Normal Distribution”. Results: The results o...
