Evaluation of Prosthesis Satisfaction, Psychological Status, and Quality of Life in Lower-Extremity Amputee Patients: A Pilot Study.

BACKGROUND: There are various factors affecting the use of prostheses. This study was aimed to examine satisfaction, psychological state, quality of life, and the factors affecting these in individuals who use prostheses because of lower-extremity amputation. METHODS: Sixty-three patients were included in this study. Demographic data and features related amputation and prosthesis were recorded. Quality of life was evaluated with the Nottingham Health Profile (NHP), anxiety and depression levels were evaluated with the Hospital Anxiety Depression Scale (HADS), body image was evaluated by the Amputee Body Image Scale (ABIS), prosthesis satisfaction was evaluated with the Prosthesis Satisfaction Questionnaire (PSQ), and the relationship between them was examined. RESULTS: There was a positive correlation between all HADS scores, NHP-emotional reactions, NHP-sleep, NHP-social isolation, NHP-total, and ABIS (P < .05). A negative correlation was found between HADS-anxiety and PSQ results (r = -0.394, P = .003). A positive correlation was found between HADS-depression scores and NHP-pain, NHP-emotional reactions, NHP-social isolation, NHP-total, and ABIS (P < .05); and a negative correlation was found with PSQ questionnaire scores (r = -0.427, P = .001). There was a positive correlation between HADS-total scores and all parameters except NHP-energy level and ABIS (P < .05). A positive correlation was found between ABIS and all parameters except NHP-energy level (P < .05). A negative correlation was found between PSQ and NHP-social isolation, NHP-physical activity, and NHP-total scores (r = -0.312, P = 0.019; r = -0.312, P = .019; and r = -0.277, P = .039, respectively). The presence of residual extremity pain was found to be an effective factor on the psychological state (ß = 0.429, P = .001). The presence of residual limb pain and phantom pain were found to be effective factors on the prosthesis satisfaction (ß = -0.41, P = .001; and ß = -0.406, P = .001, respectively). The presence of residual extremity pain and anxiety level were found independent risk factors on the NHP (ß = -0.401, P = .006; and ß = -0.445, P = .006, respectively). CONCLUSIONS: Individuals using prostheses because of lower-extremity amputation should be examined in detail from various perspectives.

Ultrasound-guided genicular nerve radiofrequency treatment: prospective randomized comparative trial of a 3-nerve protocol versus a 5-nerve protocol.

OBJECTIVES: Genicular nerve radiofrequency procedures increasingly are being performed to treat chronic pain due to knee osteoarthritis. Targeting additional sensory nerves and improving target identification by using ultrasound guidance could improve treatment success. The aim of this study was to compare the effectiveness of targeting only the traditional genicular nerves versus targeting the traditional genicular nerves plus 2 additional sensory nerves in ultrasound-guided genicular nerve radiofrequency procedures in patients with chronic knee osteoarthritis. METHODS: A total of 80 patients were randomized into 2 groups. Patients in the 3-nerve-targeted group received a genicular radiofrequency procedure in which the traditional genicular nerves were targeted: the superior lateral, superior medial, and inferior medial nerves. The 5-nerve-targeted group received a genicular radiofrequency procedure in which the recurrent fibular and infrapatellar branches of the saphenous nerve were targeted in addition to the traditional genicular nerves. The numeric rating scale, Short Form-36, Western Ontario and McMaster Universities Arthritis Index, Quantitative Analgesic Questionnaire, and patient satisfaction were evaluated before treatment, at week 1 after treatment, and at months 1, 3, and 6 after treatment. RESULTS: Both techniques provided significant pain reduction and functional improvement up to 6 months after the procedure (P < .05). The 5-nerve-targeted group showed significant improvement with regard to the numeric rating scale, Western Ontario and McMaster Universities Arthritis Index total, and Short Form-36 score compared with the 3-nerve-targeted group at each follow-up point. No differences in the Quantitative Analgesic Questionnaire or patient satisfaction scores were observed between the groups. CONCLUSIONS: The ultrasound-guided 5-nerve-targeted technique is a safe method and a more effective therapeutic procedure than the traditional 3-nerve-targeted technique for chronic knee osteoarthritis.

Acute bilateral foot drop in a chronic alcoholic patient.

Peroneal palsy is compression neuropathy of the peroneal nerve, which presents with foot drop. Patients with unilateral peroneal nerve palsy are frequently encountered in clinical practice. Although bilateral peroneal nerve palsy is rare, bilateral foot drop due to peroneal nerve palsy is much less common. The main complaint is often walking difficulty due to weakened ankle dorsiflexor muscles. Medical history and physical examination are always a part of the diagnosis, and the most useful method is electroneuromyography to evaluate the degree of the lesion. In this report, we present a 52-year-old male unconscious patient with chronic alcoholism admitted with acute bilateral foot drop and discuss clinical assessment, diagnosis, and treatment planning of this rare case of peroneal palsy after lying in the prone position in the light of literature data.

The effect of task-oriented electromyography-triggered electrical stimulation of the paretic wrist extensors on upper limb motor function early after stroke: a pilot randomized controlled trial.

The combined effect of task-oriented motor training and electromyography (EMG)-triggered electrical stimulation (ES) has been examined in chronic stroke, but there are no published reports in patients with early stroke. Therefore, the purpose of this study was to determine the short-term and long-term effects of task-oriented EMG-triggered ES on upper limb motor function in acute/subacute stroke. Twenty-seven patients with stroke within the first 3 months after stroke onset were randomly allocated to an experimental group and a control group. Twenty-three patients (12 patients in the experimental group and 11 patients in the control group) completed the study. The control group received a conventional physical therapy for 20 sessions, and the experimental group received task-oriented EMG-triggered ES therapy for the wrist/finger extensors in addition to conventional physical therapy for 5 sessions a week for 4 weeks. Primary outcome measures were the Action Research Arm Test, the Brunnstrom stages of the hand/upper extremity, and the motor Functional Independence Measure. All patients were evaluated before the treatment, after the treatment, and at 3 months. The parametric and nonparametric statistics at the 5% level of significance (α=0.05) was used for testing the differences between the two groups at each main end point. At the end of the treatment, the experimental group showed significantly greater improvements in Brunnstrom stages and ARAT grasp/grip/pinch scores, but not motor Functional Independence Measure scores, when compared with the control group. The differences between the 3-months and postintervention evaluations were not significant between the two groups suggesting retention of the postintervention gains. Our results indicate that task-oriented EMG-triggered ES training may result in improvements in the paretic upper limb function in patients with acute/subacute stroke that are superior to the conventional treatment.

Effects of functional electrical stimulation-cycling on shoulder pain and subluxation in patients with acute-subacute stroke: a pilot study.

Functional electrical stimulation (FES)-cycling is a technique used to provide voluntary muscle contraction during a functional task. The aims were primarily to determine the effects of FES-cycling on shoulder pain and subluxation, and secondarily to evaluate the improvement of upper extremity motor function in patients with acute-subacute stroke patient. In this prospective trial, 21 patients with acute-subacute stroke, randomly assigned into the FES-cycling group or the standard rehabilitation program (control group). Analyses of shoulder subluxation were carried out by radiography. The numeric rating scale was used to evaluate the intensity of pain, Fugl-Meyer and Frenchay arm tests for motor function, and functional independence measure for functional status. The outcome data were evaluated at baseline and at the end of 4-week treatment. Intragroup comparisons showed improvement of acromiohumeral distance, Fugl-Meyer assessment, and functional independence measure in both groups after treatment. In intergroup comparison, FES-cycling group exerted better outcomes in shoulder pain compared with the control group (P=0.015). Correlation analyses demonstrated only positive correlation between shoulder subluxation and pain (P=0.022). FES-cycling was superior to standard rehabilitation therapy for shoulder pain relief in patients with acute-subacute stroke. Therefore, combining FES-cycling with a standard rehabilitation program alleviates shoulder pain and may prevent development of shoulder subluxation over time.

The validation of the PRISMA-7 questionnaire in community-dwelling elderly people living in Antalya, Turkey.

BACKGROUND: The screening of frailty in older adults is an important issue in the preventive approach in medicine. Frailty is one of the leading causes of morbidity and premature mortality in older adults. OBJECTIVE: The aim of this study was to validate the PRISMA-7 questionnaire in community-dwelling elderly people living in Antalya, Turkey. METHODS: This study was cross-sectional and observational in nature and was conducted in Antalya (Turkey) from February 2016 to April 2017. One hundred fifty patients participated in this study. PRISMA-7 and the CSHA Clinical Frailty Scale were applied to these patients along with a questionnaire on socio-demographics. No translations were available for the PRISMA-7 or the CSHA in Turkish language. The PRISMA-7 and the CSHA Clinical Frailty Scale were translated by two translators to Turkish language; after compilation and agreeing to one Turkish translation, the text was translated back by two translators to English. The translation was then compiled to one text and compared with the original text. After agreement on the translation, both translations were piloted in 10 elderly people. The final form has been applied in this study. Data of the ten piloted patients have not been included into the dataset. Data were analyzed by IBM-SPSS version 22, using descriptive statistics, Pearson product-moment correlation, and receiver operator characteristic (ROC) analysis. The level of significance was set at 0.05. RESULTS: Our study showed that participants were in average vulnerability to frailty. The test-retest reliability score for the PRISMA-7 Scale and for the CSHA Clinical Frailty Scale were (r= 99.2; p<0.001) and (r=97.5; p<0.05), respectively. After using CSHA Clinical Frailty Scale as a reference standard, PRISMA-7 showed that the area under ROC curve (AUC) was 0.903; which is the best accuracy; and medium level for internal consistency (Cronbach's α =0.714) as a measure for reliability. A cut-off point of 4 or higher for PRISMA-7revealed high sensitivity (81.5%) and specificity (88.2%) for frailty. CONCLUSION: We would recommend PRISMA-7 as a reliable and valid instrument, with high-level accuracy in the screening process of frailty.

Comparison of microRNA profiles between benign and malignant salivary gland tumors in tissue, blood and saliva samples: a prospective, case-control study / Comparação de perfis de microRNA entre tumores de glândula salivar benignos emalignos em amostras de tecido, sangue e saliva: estudo caso-controle prospectivo

Abstract Introduction: Salivary gland tumors (SGTs) are rare head and neck malignancies consisting of a spectrum of tumors with different biological behaviors. Objective: In this study we aimed to find out differential expression of microRNA profiles between benign and malignant SGTs. Methods: We investigated the possible role of 95 microRNAs in the 20 patients with salivary gland tumors with comparison of 17 patients without malignancy or salivary gland diseases. Sixteen of the tumors were benign (seven pleomorphic adenomas, nine Warthin tumors), four of them were malignant (two squamous cell carcinomas, one high grade mucoepidermoid carcinoma, one adenocarcinoma). Serum and saliva samples were collected from both patients and control group. Tissue samples of tumor masses were also collected from patient group. Results: Among studied microRNAs miR-21, miR-23a, miR-27a, miR-223, miR-125b, miR-126, miR-146a, miR-30e were down regulated in the benign group compared to control group in the serum samples (p-values are 0.04, 0.00005, 0.00005, 0.0022, 0.031, 0.00008, 0.044, and 0.0007, respectively). When tissue samples were studied miR-21, miR-31, miR-199a-5p, miR-146b, miR-345 were up-regulated in the malignant group compared to benign group (p values are 0.006, 0.02, 0.013, 0.013, 0.041, respectively). miR-30e showed statistically significant up-regulation in malignant tumor group's plasma samples compared to benign group (p = 0.034). There was no statistically significant difference in saliva samples between groups. Conclusion: Our results showed that different microRNAs may play role in salivary tumor pathogenesis according to biological behavior. Although there was no difference in saliva samples between groups, according to tissue and serum samples miR-21 and 30e may have an important role; since they were down-regulated in benign tumors whereas up-regulated in malignant ones.

O miR-30e apresentou suprarregulação estatisticamente significativa em amostras deplasma do grupo de tumor maligno em relação ao grupo benigno (p = 0,034). Não houve diferençaestatisticamente significativa em amostras de saliva entre os grupos. Conclusão: Nossos resultados mostraram que diferentes microRNA podem desempenhar umpapel na patogenia do tumor salivar de acordo com o comportamento biológico. Embora nãotenha havido diferença em amostras de saliva entre os grupos, de acordo com as amostras detecido e de soro, miR-21 e 30e podem ter um papel importante, já que foram infrarreguladosnos tumores benignos enquanto suprarregulados nos tumores malignos.

A Rarely Seen Complication That Causes Increase in Morbidity in Tetraplegic Patients: Zenker Diverticula.

Although spinal cord injury (SCI) damages the spinal cord, physiological changes due to SCI can affect many organs and systems of the human body. While respiratory problems are common following cervical SCI, dysphagia is a relatively uncommon secondary complication that occurs after cervical SCI. We report a case of recurrent aspiration pneumonia due to Zenker diverticulum in 26-year-old tetraplegic patient with a chronic history of silent aspirations and dysphagia contributing to functional disability.

Comparing the effectiveness of ultrasound-guided versus blind steroid injection in the treatment of severe carpal tunnel syndrome

Background/aim: This study aimed to compare the effectiveness of ultrasound (US)-guided injection versus blind injection of corticosteroids in the treatment of carpal tunnel syndrome (CTS). Materials and methods: This prospective, randomized clinical trial included patients with severe CTS based on clinical and electrophysiological criteria. The patients were evaluated for clinical and electrophysiological parameters at baseline and 4 weeks after treatment. Symptom severity and hand function were assessed by the Boston questionnaire. The patients underwent blind injection or US-guided injection. Results: When compared with baseline, both groups showed significant improvement in Boston questionnaire scores and all electrophysiological parameters. Significant differences were observed between the groups for clinical parameters (Boston Symptom Severity Scale: P = 0.007; Functional Status Scale: P < 0.001) in favor of the US-guided group. Conclusion: This study demonstrated that both US-guided and blind injections were effective in reducing symptoms and improving hand function. US-guided injections may yield more effective clinical results in the short-term than blind injections in the treatment of patients with severe CTS.

The Role of Oxidative Stress and Inflammatory Mediators in Benign Paroxysmal Positional Vertigo.

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral cause of vertigo. It can be defined as transient vertigo induced by rapid changes in head position associated with a characteristic paroxysmal positional nystagmus. The aim of this study was to search for the possible role of oxidative stress and inflammatory mediators in the pathogenesis of BPPV. MATERIALS AND METHODS: Total antioxidant status as well as paraoxonase, tumor necrosis factor alpha, interleukin (IL) 6, and IL-1ß levels were evaluated in peripheral venous serum samples of 30 BPPV and 30 control patients. RESULTS: Total antioxidant status levels were lower in the BPPV group than in the control group (p=0.008). After Epley's repositioning maneuver in the vertigo group, there was a statistically significant decline in IL-1ß levels at the first and third month visits (p=0.014 for first month and p=0.013 for third month). CONCLUSION: Our findings suggested that IL-1ß and oxidative stress contributed to the pathogenesis of BPPV.

Blink reflex in migraine headache.

OBJECTIVE: Activation of trigeminovascular system is thought to play an important role in migraine pathogenesis. Blink reflex (BR) test is an easy method to study the trigeminal system. Latencies recorded in BR test were evaluated to examine neurophysiological changes that occur in migraine patients. METHODS: A total of 40 patients diagnosed with migraine (9 with aura and 31 without aura) according to the International Headache Society (IHS) International Classification of Headache Disorders, 2nd edition, and 30 healthy control subjects were assessed using BR test. Supraorbital nerve was stimulated on each side, and unilateral early component (R1), and bilateral late component (R2) latencies were evaluated. RESULTS: Significantly longer latency values were recorded on both right and left sides (RR1 and LR1) as well as both ipsilateral and contralateral R2 on the left side (LR2i and LR2c) in the migraine group compared to the control group. Longer RR1 and LR1 latencies were found in patients with migraine who had an attack at the time of study (p<0.01). There was no statistically significant correlation between the location of pain and latencies in the interictal period (p>0.05). But significantly longer R1 and R2i latencies were found at the symptomatic side of patients examined during the headache attack (p=0.037 and p=0.028 respectively). There was no statistically significant correlation between the recorded latencies and gender, attack duration, attack frequency and migraine type (p>0.05). CONCLUSION: Results of BR test in the present study are thought to point to a dysfunction in brainstem and trigeminovascular connections of patients with migraine headache and support the trigeminovascular theory of migraine.

Reproducible deep-inspiration breath-hold irradiation with forward intensity-modulated radiotherapy for left-sided breast cancer significantly reduces cardiac radiation exposure compared to inverse intensity-modulated radiotherapy.

AIMS AND BACKGROUND: To investigate the objective utility of our clinical routine of reproducible deep-inspiration breath-hold irradiation for left-sided breast cancer patients on reducing cardiac exposure. METHODS AND STUDY DESIGN: Free-breathing and reproducible deep-inspiration breath-hold scans were evaluated for our 10 consecutive left-sided breast cancer patients treated with reproducible deep-inspiration breath-hold. The study was based on the adjuvant dose of 50 Gy in 25 fractions of 2 Gy/fraction. Both inverse and forward intensity-modulated radiotherapy plans were generated for each computed tomography dataset. RESULTS: Reproducible deep-inspiration breath-hold plans with forward intensity-modulated radiotherapy significantly spared the heart and left anterior descending artery compared to generated free-breathing plans based on mean doses - free-breathing vs reproducible deep-inspiration breath-hold, left ventricle (296.1 vs 94.5 cGy, P = 0.005), right ventricle (158.3 vs 59.2 cGy, P = 0.005), left anterior descending artery (171.1 vs 78.1 cGy, P = 0.005), and whole heart (173.9 vs 66 cGy, P = 0.005), heart V20 (2.2% vs 0%, P = 0.007) and heart V10 (4.2% vs 0.3%, P = 0.007) - whereas they revealed no additional burden on the ipsilateral lung. Reproducible deep-inspiration breath-hold and free-breathing plans with inverse intensity-modulated radiotherapy provided similar organ at risk sparing by reducing the mean doses to the left ventricle, left anterior descending artery, heart, V10-V20 of the heart and right ventricle. However, forward intensity-modulated radiotherapy showed significant reduction in doses to the left ventricle, left anterior descending artery, heart, right ventricle, and contralateral breast (mean dose, 248.9 to 12.3 cGy, P = 0.005). The mean doses for free-breathing vs reproducible deep-inspiration breath-hold of the proximal left anterior descending artery were 1.78 vs 1.08 Gy and of the distal left anterior descending artery were 8.11 vs 3.89 Gy, whereas mean distances to the 50 Gy isodose line of the proximal left anterior descending artery were 6.6 vs 3.3 cm and of the distal left anterior descending artery were 7.4 vs 4.1 cm, with forward intensity-modulated radiotherapy. Overall reduction in mean doses to proximal and distal left anterior descending artery with deep-inspiration breath-hold irradiation was 39% (P = 0.02) and 52% (P = 0.002), respectively. CONCLUSIONS: We found a significant reduction of radiation exposure to the contralateral breast, left and right ventricles, as well as of proximal and especially distal left anterior descending artery with the deep-inspiration breath-hold technique with forward intensity-modulated radiotherapy planning.

Eosinophilic jejunitis presenting as intractable abdominal pain.

Eosinophilic gastroenteritis is an uncommon disease characterized by eosinophilic infiltration of the gastrointestinal tract. The clinical manifestations are related to the layer(s) and extent of the bowel involved. In this paper, we present a case of intractable abdominal pain caused by jejunal submucosal eosinophilic infiltration without mucosal involvement, diagnosed by deep endoscopic biopsies. The patient was successfully treated with steroids without need for surgery for diagnosis or therapy.

Successful intravenous immunoglobulin therapy in a case of acute fulminant myocarditis.

Fulminant myocarditis is an inflammatory process that occurs in the myocardium and causes acute-onset heart failure. Its prognosis is poor unless patients are promptly and aggressively supported. Although an autoimmune mechanism has been postulated for myocarditis, immunomodulatory treatment strategies are still under investigation. We report on a 30-year-old woman with acute myocarditis, whose condition rapidly deteriorated despite standard medical therapy. High-dose intravenous immunoglobulin therapy (70 g/day for 2 days) was given and the patient showed dramatic improvement on the second day. Left ventricular ejection fraction increased from 32% to 40% and to 50% at 24 and 48 hours of treatment, respectively. She was discharged on the tenth day with normal ejection fraction. She was free of cardiac events during a two-year follow-up. High-dose intravenous immunoglobulin may be potentially useful in selected patients, especially if given early in acute fulminant myocarditis.

Genetic polymorphism of VEGF-1154 (A/G) in laryngeal squamous cell carcinoma.

BACKGROUND: Angiogenesis has been shown to be increased in various human tumors including head and neck squamous cell carcinoma (SCC). Vascular endothelial growth factor (VEGF) is thought to be one of the most important angiogenic factors in tumorigenesis. In this study, we aimed to investigate whether polymorphism of VEGF-1154 (A/G) genotypes are associated with the risk of laryngeal SCC. METHODS: A prospective, randomized, case-control study in a tertiary university hospital was done. The study group consisted of 57 Caucasian patients with laryngeal SCC and 89 control subjects. Blood samples were obtained before surgery or from the patients under follow-up to 5 years after surgery. VEGF-1154 (A/G) genotypes were detected by real-time polymerase chain reaction with thermal cycler system. RESULTS: According to the high-risk (GG) genotype, the difference between the patient and control groups was statistically significant (OR 0.43, 95% CI=0.19-0.95, p=0.037). CONCLUSIONS: GG genotype of the VEGF gene may increase the risk of laryngeal SCC in this population. VEGF gene polymorphism may be an important potential genetic and therapeutic marker of laryngeal SCC.

Cranial magnetic resonance imaging findings in patients with migraine.

OBJECTIVE: To investigate the frequency of cranial magnetic resonance imaging abnormalities in patients with migraine and their relationship to type, duration, and frequency of migraine attacks. METHODS: Forty-five patients (43 women, 2 men) with migraine whose ages ranged between 19 and 53 years (mean, 40.91 [SD, 7.69]) were evaluated. Of the 45 patients, 20 had migraine with aura and 25 had migraine without aura, according to the diagnostic criteria of the International Headache Society. RESULTS: In 13 (28.8%) of 45 patients, white matter foci were present on magnetic resonance imaging. Eight of these patients (61.5%) had migraine with aura, and 5 patients (38.4%) had migraine without aura. The presence of white matter foci was significantly higher in the patients with aura (8 [40%] of 20) than in those without aura (5 [20%] of 25). It was found that as the frequency of attacks per month increased, the number of patients with white matter foci also increased. Although the mean duration of migraine was longer in patients with white matter foci (149.5 months [SD, 87.9]) than in those without white matter foci (134.1 months [SD, 88.3]), there was no significant difference (P >.05). CONCLUSION: Although there are no specific magnetic resonance imaging findings peculiar to migraine, detection of white matter foci should be taken into consideration in patients with migraine (especially migraine with aura). Frequency of attacks is an important indicator of existence of white matter foci.
