Silver and salicylic acid-chitosan nanoparticles alter indole alkaloid production and gene expression in root and shoot cultures of Isatis tinctoria and Isatis ermenekensis.

Isatis spp. are well-known for their industrial significance due to natural sources of indigotin and indirubin, important indole alkaloids, used in the dye and pharmaceutical industries. In this study, silver nanoparticles (AgNP) and salicylic acid-chitosan nanoparticles (SA-CNP) were synthesized and applied to enhance the production of indigotin and indirubin in shoot and root cultures of Isatis tinctoria and Isatis ermenekensis. Different doses of AgNP and SA-CNP were administered to three-week-old shoot and root cultures, and the effects were assessed at 12, 24, and 48 h. The harvested samples were analyzed to quantify indigotin and indirubin levels. Furthermore, the expression levels of It-TSA and CYP79B2 genes, known to be involved in indole alkaloid biosynthesis, were determined. In I. tinctoria roots, the highest levels of indigotin and indirubin were observed after applying 150 mg L-1 of SA-CNP for 48 h while in I. ermenekensis shoots, indigotin and indirubin reached the maximum levels with the application of 8 mg L-1 AgNP for 48 h. NP application had no remarkable effects on the accumulation of indigotin and indirubin in I. tinctoria shoots and I. ermenekensis roots compared to controls. Additionally, shoot cultures demonstrated superior indirubin production, which significantly increased with AgNP applications. The gene expression analysis also exhibited significant correlations with the changes in indigotin and indirubin levels. The findings of this study lay the groundwork for enhancing in vitro production of indigotin and indirubin in Isatis species through NP applications, and for developing high-capacity production strategies by determining optimal dosages in scale-up studies.

Effect of swallowing rehabilitation using traditional therapy, kinesiology taping and neuromuscular electrical stimulation on dysphagia in post-stroke patients: A randomized clinical trial.

OBJECTIVE: We aimed to evaluate the functional recovery of stroke patients with orophyaryngeal dysphagia after treatment with traditional swallowing therapy (TST), neuromuscular electrical stimulation (NMES), and kinesiology taping (KT), by using clinical swallowing assessments and objective fiberoptic endoscopic evaluation of swallowing (FEES). METHODS: A total of 37 patients were randomized in three groups: those who received TST and NMES as Group 1 (n:12), those who received both TST and KT as Group 2 (n:13), and those who received TST, NMES, and KT together as Group 3 (n:12). Patients were evaluated before treatment, after treatment, and three months after treatment onset with bedside water-swallow test, Eating Assessment Tool (EAT-10), Functional Oral Intake Scale (FOIS), penetration-aspiration scale (PAS), and National Institute of Health-Swallow Safety Scale (NIH-SSS). FOIS, PAS, and NIS-SSS were completed according to results of fiberoptic endoscopic evaluation of swallowing (FEES). RESULTS: A statistically significant decrease was observed in bedside water-swallow test, EAT-10, PAS, and NIH-SSS scores in all treatment groups 5 weeks and 3 months after treatment onset compared to pre-treatment scores (p < 0.05). There was a statistically significant increase in FOIS scores 5 weeks and 3 months after treatment compared to pretreatment scores in all treatment groups (p < 0.05). When the pre-treatment, 3-week, and 5-month swallow scale scores of all groups were compared, there was no significant different difference in terms of bedside water-swallow test, EAT-10, FOIS, PAS, or NIH-SSS scores (p > 0.05). CONCLUSION: According to the results of our study, KT is a new option in the treatment of stroke-related dysphagia, is an effective treatment approach and its efficacy is maintained throughout long-term follow-up.

Assessment of pain, care burden, depression level, sleep quality, fatigue and quality of life in the mothers of children with cerebral palsy.

The aim of this study were to evaluate pain, care burden, depression level, sleep quality, fatigue and quality of life (QoL) among a group of mothers of children with cerebral palsy (CP) and to compare their results with a group of healthy controls. The study involved 101 mothers who had children with CP and 67 mothers who had a healthy child as the control group. Pain, care burden, depression level, sleep quality, fatigue and QoL of all the participants were evaluated by the numerical rating scale, the Zarit care burden scale (ZCBS), the beck depression inventory (BDI), the Pittsburgh sleep quality index (PSQI), the checklist individual strength (CIS) and the short form-36 (SF-36), respectively. Numerical rating scale value was 3.57 ± 2.96 in the patient group. When the two groups were compared, the CP group showed higher scores for ZCBS, BDI, PSQI, total CIS and SF-36 subscales of general health and vitality whereas the scores for role physical, role emotional, mental health and mental component summary were found to be lower in the patients, compared to the control group. Reducing caregiving burden of the mothers' by other family members and increasing psychosocial supports may help improve the mother's health status.

Effectiveness of physical therapy and exercise on pain and functional status in patients with chronic low back pain: a randomized-controlled trial.

OBJECTIVES: This study aims to investigate the effect of physical therapy modalities on pain and functional status in patients with non-specific low back pain. PATIENTS AND METHODS: Between February 2011 and August 2013, a total of 104 patients (38 males, 66 females; mean age 49.3±12.5 years; range 34 to 62 years) with non-specific chronic low back pain for more than 12 weeks without any neurological deficit were included in this randomized-controlled study. The patients were divided into two groups: physical therapy group (n=52) and control group (n=52). Both groups were given exercise and medical treatment; physiotherapy modalities were also applied in the physical therapy group. The patients were assessed using the Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and Istanbul Low Back Pain Disability Index (ILBP) before treatment and at two weeks, three months, and one year after treatment. RESULTS: A total of 100 patients completed one-year follow-up. In both groups, the VAS, ODI, and ILBP significantly improved after treatment (p<0.01), compared to before treatment values. There were statistically significant differences in the VAS, ODI, and ILBP scores at three months and one year after treatment between the physical therapy group and control group (p<0.05). CONCLUSION: Multidisciplinary approaches including physical therapy should be implemented to provide long-term improvement in pain and functional status in the treatment of non-specific chronic low back pain.

Efficacy of Pulsed Radiofrequency Therapy to Dorsal Root Ganglion Adding to TENS and Exercise for Persistent Pain after Total Knee Arthroplasty.

The majority of patients achieve substantial pain relief and improved function after total knee arthroplasty (TKA), but a proportion continues to experience life-disturbing persistent postsurgical pain (PPSP) in the months and years after surgery. This study aimed to assess the efficacy of transcutaneous electrical nerve stimulation (TENS), exercise, and pulsed radiofrequency (PRF) treatment on pain severity, neuropathic pain, knee flexion range of motion (ROM), functional status, and patient satisfaction in patients with PPSP after TKA. This is a retrospective study of prospectively collected data. Patients who were identified retrospectively from hospital charts were divided into two groups: group 1 (n = 17) received TENS and exercise treatment and group 2 (n = 22) received TENS, exercise, and PRF application to the dorsal root ganglion (DRG). The following procedure-related parameters were collected from the special registry form: visual analog scale (VAS), Douleur Neuropathique 4 (DN4) questionnaire, knee flexion ROM, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and patient satisfaction scale scores. The mean follow-up was 253.8 ± 109 days. When the two groups were compared, a significant difference of at least 50% improvement in the VAS (activity) and a significant reduction in the DN4 scores following the last control examination were found in group 2. There was a significant reduction in total WOMAC scores in group 1 compared with group 2 for the four study periods. Higher scores for the patient satisfaction scale were found in group 1 compared with group 2 following the last control examination. Adding PRF to TENS and exercise therapy is useful in reducing the degree of pain and the neuropathic component of PPSP in patients with PPSP.

Total Knee Arthroplasty due to Knee Osteoarthritis: Risk Factors for Persistent Postsurgical Pain.

OBJECTIVE: The aim of this study was to identify whether different patient characteristics and clinical factors can be risk factors in patients with persistent postsurgical pain (PPSP) after total knee arthroplasty (TKA). METHODS: Patients who underwent TKA due to knee osteoarthritis were divided into two groups: those who experienced no or mild PPSP (Numerical Rating Scale [NRS] ≤ 3) (group 1, n = 91) and those who experienced moderate to severe PPSP (NRS > 3) (group 2, n = 183). Information on the characteristics of patients, comorbid diseases and pre-surgical NRS scores were obtained retrospectively from hospital charts. The follow-up time; pre-surgical and last control time walking distance; and ratings on the NRS, Pain DETECT Questionnaire (PDQ) and patient satisfaction scales were recorded from the standard questionnaire presented to patients during the telephone interview. RESULTS: The mean follow-up time was 22.8 ± 12.3 months. The rate of moderate to severe PPSP among patients amounted to 66.7% after TKA. No neuropathic pain was found in Group 1. In Group 2, 22.9% of patients experienced neuropathic pain, the results for 18% of patients were uncertain, and 59% of patients did not experience neuropathic pain. Group 2 had worse scores on the patient satisfaction scale following the last control time compared with Group 1. Being widowed, having a low education level, being a housewife, having employment that requires physical effort, pre-surgical pain intensity at rest and pre-surgical restricted walking distance are risk factors for Group 2. CONCLUSIONS: PPSP and the neuropathic component in PPSP after TKA are not underestimated for pain management and patient satisfaction. Subgroups of patients, particularly widowers, having a primary school education level or under, housewives, people with jobs that require physical effort, individuals with intense pre-surgical pain during rest and those suffering from pre-surgical restricted walking distance, are at higher risk of developing PPSP following TKA.

Pulsed radiofrequency applied to the dorsal root ganglia for treatment of post-stroke complex regional pain syndrome: A case series.

STUDY OBJECTIVE: Complex regional pain syndrome is a painful and disabling syndrome where the patient presents with neuropathic pain, edema, or vasomotor or pseudomotor abnormalities that are often refractory to treatment. Complex regional pain syndrome type 1 may occurs in stroke patients. Radiofrequency is a therapeutic modality that has been used for years for diseases associated with neuropathic pain. DESIGN: Case series report. SETTING: Selcuk University Hospital. PATIENTS: A 69-year-old woman and a 48-year-old women who suffered post-stroke complex regional pain syndrome type 1. INTERVENTIONS: Pulsed radiofrequency current application to the cervical dorsal root ganglia. MEASUREMENTS: Pain reduction. MAIN RESULTS: The patients had complete resolution of their symptoms, which was maintained at 10 and 5 months of follow-up. CONCLUSIONS: These cases illustrates that pulsed radiofrequency applied to cervical dorsal root ganglia might play a significant role in multi-modal approach of complex regional pain syndrome type 1 management after stroke. Further randomized, controlled studies are needed to support this argument.

The association between bone mineral density, quality of life, quality of sleep and fatigue.

OBJECTIVES: This study was undertaken to examine quality of life (QoL), the quality of sleep and fatigue level in postmenopausal women with osteoporosis (OP) but without fractures, to assess the associations between these parameters and to compare the results with those for subjects who have osteopenia or normal bone mineral density (BMD). METHODS: In this study, 113 postmenopausal osteoporosis (PMO) subjects without fractures, 172 subjects with osteopenia and 102 subjects with normal BMD were included. The severity of pain, QoL, quality of sleep and fatigue were assessed using the visual analogue scale (VAS), the QoL Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41), the Pittsburgh Sleep Quality Index (PSQI) and the Checklist of Individual Strength (CIS) questionnaire. RESULTS: No statistically significant differences between the three groups were found in terms of VAS and QUALEFFO-41 total scores (p > 0.05). On the other hand, PSQI and CIS total scores were significantly different in the PMO and osteopenia groups (P = 0.015 and 0.007, respectively) compared to the group with normal BMD. CONCLUSIONS: During the follow-up and treatment of women with PMO or osteopenia, QoL, quality of sleep and fatigue should be assessed and incorporated into treatment decisions, even in the absence of fractures.

Is pain the only symptom in patients with benign joint hypermobility syndrome?

The aims of this study were to evaluate pain, depression level, fatigue, sleep, and quality of life (QoL) among patients with benign joint hypermobility syndrome (BJHS) and to compare their results with those of healthy controls. The study involved 115 patients and 114 healthy volunteers. Pain level was rated using visual analogue scale (VAS) for all patients. Depression level, fatigue, sleep quality, and QoL of all the participants were evaluated by the Beck Depression Inventory (BDI), the Checklist Individual Strength (CIS), the Pittsburgh Sleep Quality Index (PSQI), and the Short Form-36 (SF-36), respectively. VAS value was 6.29 ± 0.94 in the patient group. Comparison of two groups showed that there were statistically significant differences between the patient group and the control group with respect to BDI, total CIS, PSQI scores, SF-36 subscales (physical function, role physical, bodily pain, general health, role emotional, and mental health), and mental component summary (p < 0.001). While pain is the predominant symptom among BJHS patients, depression, fatigue, impaired sleep, and QoL also commonly occur. Thus, all of these components should be taken into account when assessing patients with BJHS.

Spontaneous patellar tendon rupture in a case followed up for diagnosis of systemic lupus erythematosus.

Spontaneous patellar tendon rupture is a rare condition that usually occurs secondary to conditions, such as rheumatoid arthritis, systemic lupus erythematosus (SLE), and use of steroids and fluoroquinolones. This paper presents a full-thickness patellar tendon rupture detected with magnetic resonance imaging, which was performed due to pain and swelling that started spontaneously on the front side of the left knee without a history of any trauma, of a 35-year-old male patient who had been followed up for a diagnosis of SLE for approximately 4 months and who had started taking methylprednisolone 4 mg/day 4 months prior, used it for 1 month, and then stopped using it. In patients who are followed up for a diagnosis of SLE, it should be kept in mind that there is a risk of developing a spontaneous tendon rupture secondary to chronic inflammation and use of corticosteroids.

A rare cause of dysphagia: compression of the esophagus by an anterior cervical osteophyte due to ankylosing spondylitis.

Ankylosing spondylitis (AS) is a chronic inflammatory rheumatological disease affecting the axial skeleton with various extra-articular complications. Dysphagia due to a giant anterior osteophyte of the cervical spine in AS is extremely rare. We present a 48-year-old male with AS suffering from progressive dysphagia to soft foods and liquids. Esophagography showed an anterior osteophyte at C5-C6 resulting in esophageal compression. The patient refused surgical resection of the osteophyte and received conservative therapy. However, after 6 months there was no improvement in dysphagia. This case illustrates that a large cervical osteophyte may be the cause of dysphagia in patients with AS and should be included in the diagnostic workup in early stages of the disease.

The efficacy of electrical stimulation in reducing the post-stroke spasticity: a randomized controlled study.

PURPOSE: The purpose of this study is to evaluate the efficacy of surface electrical stimulation on the spasticity occurring in the wrist flexor muscles after a cerebrovascular event. METHOD: Hemiplegic patients with stage 2-3 spasticity in the wrist muscles based on the Ashworth scale were divided into two groups. Both groups were applied stretching. One group was additionally administered neuromuscular electrical stimulation (NMES) to the wrist extensors, in the form of pulsed current, 100 Hz, with a pulse duration of 0.1 msec, and a resting duration of 9 seconds, for 15 minutes to provide the maximum muscular contraction. The efficacy of the treatment was evaluated using the following: modified Ashworth scale (MAS), Fmax/Mmax ratio, Hmax/Mmax ratio, wrist extension range of motion (ROM). The daily activities were assessed by Functional Independence Measurement (FIM) and the motor recovery was evaluated by Brunnstrom motor staging. RESULTS: Both groups revealed a significant recovery after the treatment based on the MAS, the electrophysiological evaluation results, wrist ROM, FIM and Brunnstrom motor staging. The group receiving the combined treatment showed a better recovery in terms of MAS, wrist ROM, FIM and Brunnstrom motor staging compared to the group doing the stretching alone. CONCLUSIONS: The results of this study showed that NMES given together with stretching of the wrist extensor muscles was more effective than stretching of the wrist extensor muscles alone in reducing spasticity.

Effectiveness of back school for treatment of pain and functional disability in patients with chronic low back pain: a randomized controlled trial.

OBJECTIVE: To evaluate the effectiveness of the addition of back school to exercise and physical treatment modalities in relieving pain and improving the functional status of patients with chronic low back pain. DESIGN: A randomized controlled trial. PATIENTS: A total of 146 patients with chronic low back pain were enrolled in the study. METHODS: Subjects were divided into 2 groups: the back school group received exercise, physical treatment modalities and a back school programme; and the control group received exercise and physical treatment modalities. Treatment efficacy was evaluated at the end of treatment and 3 months post-treatment, in terms of pain, measured with the Visual Analogue Scale, and functional status, measured with the Oswestry Low Back Pain Disability Questionnaire. RESULTS: In both groups, Visual Analogue Scale and Oswestry Low Back Pain Disability Questionnaire were significantly reduced after therapy (p < 0.01), but the difference between the scores at the end of treatment and 3 months post-treatment was not significant. There was a significant improvement in Visual Analogue Scale and Oswestry Low Back Pain Disability Questionnaire in the back school group compared with the control group at the end of therapy and 3 months post-treatment (p < 0.05). CONCLUSION: The addition of back school was more effective than exercise and physical treatment modalities alone in the treatment of patients with chronic low back pain.

Axis I and Axis II psychiatric disorders in patients with fibromyalgia.

OBJECTIVE: To determine the current prevalence of Axis I and Axis II psychiatric disorders in patients with fibromyalgia. METHOD: The study sample includes 103 patients with fibromyalgia and 83 control subjects. Axis I and Axis II disorders were determined by structured clinical interviews. RESULTS: The rate of any Axis I psychiatric disorder (47.6% vs. 15.7%), major depression (14.6% vs. 4.8%), specific phobia (13.6% vs. 4.8%), any Axis II disorder (31.1% vs. 13.3%), obsessive-compulsive (23.3% vs. 3.6%) and avoidant (10.7% vs. 2.4%) personality disorders were significantly more common in the patient group compared to the control group. CONCLUSION: Our results suggest that a considerable proportion of patients with fibromyalgia also present with Axis I and Axis II psychopathologies.
