Introduction: Telerehabilitation (TR) is an innovative approach that can address the limited availability and restricted access to rehabilitation services, particularly during challenging times such as pandemics and natural disasters. This study focuses on understanding the desires, perceptions, and barriers that physiotherapists face when implementing TR in a developing country., Method: The study was conducted with 219 physiotherapists residing in a developing country using a web-based survey on Google Docs., Result: The findings revealed that a significant majority of physiotherapists (88.1%) recognized TR as a potential solution for individuals with physical problems during the pandemic. Additionally, 89.5% expressed satisfaction with the opportunity to receive consultations from different hospitals, indicating a positive perception of TR. However, the study also highlighted certain barriers that hindered the implementation of TR. Around 40.2% of physiotherapists reported having training deficiencies, suggesting a need for educational support in utilizing TR effectively. Furthermore, the analysis of demographic factors revealed interesting insights. It was noteworthy that the age and years of experience of physiotherapists had an impact on their willingness and adoption of TR., Conclusion: The study reveals that physiotherapists in the developing country exhibit a positive attitude towards TR and recognize its potential benefits. However, various barriers, such as training deficiencies, need to be addressed to facilitate a broader adoption of TR in their practices. Overcoming these barriers is anticipated to heighten physiotherapists' readiness to embrace TR, ultimately enhancing the accessibility and delivery of rehabilitation services., (© 2023.

Background/aim: Lumbar instability is an important condition that can be seen frequently in people with low back pain, affecting both the progression and the choice of appropriate exercise. The Lumbar Spine Instability Questionnaire (LSIQ) is a simple and low-cost tool for evaluating disturbed back stability in people with low back pain. The aim of this study is to develop the Turkish version of the LSIQ (LSIQ-T) and to evaluate its psychometric properties using the Rasch model., Materials and Methods: One hundred participants with chronic low back pain completed the LSIQ-T. The LSIQ-T was repeated for 30 participants after 1 week to establish its test-retest reliability. While internal and external construct validity were investigated using Rasch analysis and the Spearman correlation coefficient, respectively, reliability was evaluated in terms of internal consistency by Cronbach's alpha and the Person Separation Index (PSI)., Results: All items of the LSIQ-T were found to fit the Rasch model (chi-square: 34.07 (df = 15), p = 0.0033). The internal construct validity was good, the overall mean item fit residual was 0 (SD: 0.765), and the mean person fit residual was 0.322 (SD: 1.123). Internal consistency reliability was low with a PSI of 0.63 although Cronbach's alpha was acceptable (0.68). When the test-retest reliability was examined via differential item functioning (DIF) by time, none of the items showed DIF., Conclusion: The LSIQ-T is a valid unidimensional scale for the Turkish population. Although the LSIQ-T had low internal consistency, it demonstrated unidimensionality and is appropriate for use. Therefore, the LSIQ-T can be used in clinical practice and scientific research., Competing Interests: Conflicts of interest: The authors report that there is no conflict of interest with any financial organization regarding the material discussed in this manuscript., (© TÜBİTAK.)

Background and Objectives: Hypermobility Spectrum Disorder (HSD) is associated with excessive joint range of motion and the presence of musculoskeletal symptoms. The objective of this study was to examine body awareness, physical fitness parameters, fatigue levels, and musculoskeletal disorders in young adults with HSD and compare them with those without HSD., Methods: Young individuals in the age range of 18-24 years were included in the study. Joint hypermobility of individuals was determined by the Beighton Score. Evaluations were made using the Body Awareness Questionnaire, the Fatigue Severity Scale, the Eurofit Physical Fitness Test Battery, and the Cornell Musculoskeletal Discomfort Questionnaire., Results: A total of 94 healthy individuals (74 females, 20 males, mean age 21.44 years, SD ± 1.19 years), 47 with HSD and 47 without HSD, were included in the study. It was concluded that body awareness and fatigue levels were similar in two groups (p > 0.05). When physical fitness parameters were examined, there was a significant difference between the two groups in Sit and Reach test and the dominant side grip strength (p < 0.05). There was a significant difference between the two groups in the neck, back, dominant wrist, and total musculoskeletal problems (p < 0.05)., Conclusion: It was concluded that young individuals with HSD had more flexibility, lower grip strength, more pain especially in the neck and back region, and more musculoskeletal disorders in general. Joint hypermobility is a factor to be considered in evaluating functional performance in these individuals., Competing Interests: Declaration of competing interest None., (Copyright © 2022 Elsevier Ltd.

Background: The Fullerton Advanced Balance Scale (FAB) is a multi-item balance assessment test designed to measure balance in relatively higher functioning individuals. The aim of this study was to examine the reliability and validity of the Turkish version of the FAB (FAB-T) in children with cerebral palsy (CP)., Research Question: Is the Turkish version of the Fullerton Advance Balance Scale valid and reliable in determining balance problems in children with cerebral palsy and determining the underlying cause of this condition?, Methods: Forty-six children with CP participated in this study. Rasch analysis was used to investigate item adherence. Internal consistency of the FAB-T was established using Cronbach's alpha coefficient. Test-retest reliability was also evaluated. In addition, to assess concurrent validity, FAB-T scores were compared with the Pediatric Balance Scale (PBS) using the Spearman correlation coefficient., Results: The FAB-T showed satisfactory internal consistency (Cronbach's alpha value=0.94) and excellent test-retest reliability (ICC=0.99). The FAB and the PBS exhibited concurrent positive validity (r = 0.913; p < 0.001). All items of the FAB-T were found to fit the Rasch Model (Chi-square 16.01(df=20), p = 0.716)., Significance: The FAB-T is a reliable and valid tool that can be used to measure balance skills and to identify the source of the problem in children with CP., (Copyright © 2022 Elsevier B.V.

Background and Objective: Extrapulmonary sarcoidosis is common, and is almost always associated with concomitant thoracic involvement. Extrapulmonary manifestations vary on the basis of gender, age at presentation and ethnicity. The aim of this study was to investigate extrapulmonary involvement in patients with sarcoidosis in Turkey., Methods: This study was conducted by Turkish Thoracic Society Clinical Problems Study Group. New cases of sarcoidosis between 1 June 2004 and 31 May 2006 were recorded on electronic case record forms sent to all potential investigators and information about extrapulmonary involvement was collected., Results: One hundred and nineteen of 293 patients (83 female, 36 male, mean age = 45 ± 12 years) had extrapulmonary involvement in this study (40.6%). The median time to diagnosis was 6 months and this was longer than patients with just thoracic sarcoidosis (P = 0.001). Extrapulmonary symptoms were present in 181 (61.8%) patients, and skin lesions, arthralgia and back pain were the commonest (33.4%, 20.8% and 16.4%, respectively). Incidence of organ involvement was independent of age with the exception of ocular involvement, which was higher in those under the age of 40 years (P = 0.007)., Conclusions: Skin and peripheral lymph node involvement were the most common sites of extrapulmonary involvement and ocular involvement was more common in those under the age of 40 years in patients with sarcoidosis in a Turkish population., (© 2011 The Authors.

Sarcoidosis is an idiopathic granulomatous disease. It usually affects the lung. The diagnosis may be problematic since the known causes of granulomatous inflammation must be excluded. This multicenter study aimed to evaluate the clinical presentations and diagnostic approaches of sarcoidosis. The study protocol was sent via internet, and the participants were asked to send the information (clinical, radiological and diagnostic) on newly diagnosed sarcoidosis cases. 293 patients were enrolled within two years. Pulmonary symptoms were found in 73.3% of the patients, and cough was the most common one (53.2%), followed by dyspnea (40.3%). Constitutional symptoms were occured in half of the patients. The most common one was fatigue (38.6%). The most common physical sign was eritema nodosum (17.1%). The most common chest radiograhical sign was bilateral hilar lymphadenomegaly (78.8%). Staging according to chest X-ray has revealed that most of the patients were in Stage I and Stage II (51.9% and 31.7%, respectively). Sarcoidosis was confirmed histopathologically in 265 (90.4%) patients. Although one-third of the bronchoscopy was revealed normal, mucosal hyperemi (19.8%) and external compression of the bronchial wall (16.8%) were common abnormal findings. The 100% success rate was obtained in mediastinoscopy among the frequently used sampling methods. Transbronchial biopsy was the most frequently used method with 48.8% success rate. Considering sarcoidosis with its most common and also rare findings in the differential diagnosis, organizing the related procedures according to the possibly effected areas, and the expertise of the team would favour multimodality diagnosis.

A 71-year-old male was diagnosed with a non-small cell lung cancer (NSCLC) within the radiotherapy field that was used for the treatment of a small cell lung cancer (SCLC) 11 years ago. At the initial diagnosis in 1996 the patient had limited-stage SCLC located in the right upper lobe of the lung with mediastinal involvement. He received 4 cycles of chemotherapy and then mediastinal radiotherapy. With a complete response after chemoradiotherapy he was given prophylactic cranial radiotherapy. After 11 years of disease-free period a new mass in left lower lobe of the lung was detected. Bronchoscopic biopsy showed second lung cancer with epidermoid histology. Although the incidence of a second lung cancer is higher in SCLC survivors, this is a unique case in the literature with second NSCLC developing in the previously irradiated side of limited-stage SCLC.

This study investigated the reusability of waste material from the tile manufacturing industry as an alternative material to natural pozzolan trass. Yield strength values of mortar made from Portland cement (CEM 142.5), were measured by adding glazed ceramic waste and trass at various weight ratios (5 to 40%). The test results proved that the strength values at 2, 7, and 28 days gave good results for concentrations of waste materials less than 5-10% in the cement. A decrease in strength was observed at higher concentrations. Mathematical modelling results showed a logarithmic correlation between the mortar strength and weight fraction of cement.

The electrochemical behavior of Ar(2)SeCl(2), and Ar(2)Se(2), (Ar:CH(3)OC(6)H(5); C(2)H(5)OC(6)H(5)) in acetonitrile (AN) containing tetrabutylammonium tetrafluoroborat (TBAFB) as supporting electrolyte was studied on a stationary electrode (spe). In order to elucidate the electrode reactions linear potential scan, cyclic voltammetry and controlled-potential coulometry were employed using a platinum electrode. It is shown that Ar(2)SeCl(2) and Ar(2)Se(2) are reduced and oxidized to Ar(2)Se, Ar(2)Se(2)Ar(2), Se, and Ar(2)Se(BF(4))(2). It is generally accepted that as final electrochemical reduction products, the corresponding Ar(2)Se, Ar(4)Se(2), and Se were formed. The disappearance of the diorganoselenium and selenide in the course of the coulometric experiments was validated by measuring the limiting current of the voltammetric waves at spe and UV spectrometry.

Setting: Mycobacterium tuberculosis bacilli spread by the hematogenous route during primary infection and reactivate later., Objective: To compare factors influencing the reactivation site., Design: A total of 236 pulmonary tuberculosis (PTB) and 139 extra-pulmonary TB (EPTB) cases were compared in terms of age, co-morbid disease, immunosuppressive drug use, history of contact with a PTB case in a close relative, history of tuberculosis, smoking habit and alcohol intake., Results: The sex ratio of EPTB and PTB cases was significantly different (P < 0.001): respectively 74% of EPTB cases and 34% of PTB cases were females; 53.3% of PTB cases and 23% of EPTB cases were smokers (P < 0.001); and the disease appeared within the first 5 years after contact in 23.7% of EPTB cases compared to 72.6% in PTB cases (P < 0.001). In logistic regression analysis, gender (OR = 3.69), smoking habit (OR = 0.54) and interval between contact and disease (OR = 1.07) were found to influence the reactivation site., Conclusion: The probability of PTB development was higher in males, in smokers and within the first 5 years of contact. In contrast, the probability of EPTB development was higher in females and after 5 years of contact.

Study Objectives: Correct detection of bone metastases in patients with non-small cell lung cancer (NSCLC) is crucial for prognosis and selection of an appropriate treatment regimen. The aim of this study was to investigate the role of whole-body bone scanning (WBBS) and clinical factors in detecting bone metastases in NSCLC., Design and Patients: One hundred twenty-five patients with a diagnosis made between 1998 and 2002 were recruited (squamous cell carcinoma, 54.4%; adenocarcinoma, 32.8%; non-small cell carcinoma, 8.8%; large cell carcinoma, 4%). Clinical factors suggesting bone metastasis (skeletal pain, elevated alkaline phosphatase, hypercalcemia) were evaluated. WBBS was performed in all patients, and additional MRI was ordered in 10 patients because of discordance between clinical factors and WBBS findings., Measurements and Results: Bone metastases were detected in 53% (n = 21) of 39 clinical factor-positive patients, 5.8% (n = 5) of 86 clinical factor-negative patients, and 20.8% of total patients. The existence of bone-specific clinical factors as indicators of metastasis presented 53.8% positive predictive value (PPV), 94.2% negative predictive value (NPV), and 81.6% accuracy. However, the findings of WBBS showed 73.5% PPV, 97.8% NPV, and 91.2% accuracy. Adenocarcinoma was the most common cell type found in patients with bone metastasis (39%). The routine bone scanning prevented two futile thoracotomies (8%) in 25 patients with apparently operable lung cancer., Conclusions: In spite of the high NPV of the bone-specific clinical factors and the high value obtained in the false-positive findings in the bone scan, the present study indicates that in patients for whom surgical therapy is an option, preoperative staging using WBBS can be helpful to avoid misstaging due to asymptomatic bone metastases.

Platelets have the capacity to release mediators with potent inflammatory or anaphylactic properties. Platelet factor-4 (PF4) and beta-thromboglobulin (BTG) are two of these mediators. On the other hand, plasminogen activator inhibitor-1 (PAI-1) and tissue plasminogen activator (tPA) are two important mediators of fibrinolysis. Both mediators are secreted mainly by vascular endothelium. Plasma levels of PF4, BTG, PAI-1, and tPA may show changes in chronic inflammatory diseases such as asthma. This study examined the role of thrombocytes and the function of the endothelium in asthmatic patients during an attack and during a stable phase. Eighteen patients with known allergic asthma who came to our emergency department with an asthma attack and 14 control subjects were included in the study. Blood samples were taken after starting therapy with salbutamol inhalation. Lung function tests were performed after receiving the first emergency therapy for asthma. Plasma levels of PF4, BTG, PAI-1, tPA were determined before starting steroid therapy and after receiving 1 week of steroid therapy. Plasma levels of PF4 among patients with an asthma attack were significantly higher than those of controls (150.5+/-8.92 IU/mL vs. 92.5+/-7.63 IU/mL, p<0.001). A further increase in plasma PF4 levels was detected after steroid therapy (163.5+/-9.16 IU/mL). Plasma BTG levels of patients on admission were not statistically different from those in the control group (140.4+/-6.34 IU/mL vs. 152.2+/-8.71 IU/mL). An increase was detected after therapy (171.6+/-7.27 IU/mL) and post-treatment plasma levels were statistically meaningful versus the controls. Plasma levels of tPA and PAI were statistically higher than those in controls in asthmatic patients on admission (6.01+/-2.72 vs. 5.4+/-2.3 ng/mL for tPA and 75.2+/-27.2 ng/mL vs. 32.7+/-14.3 ng/mL for PAI-1). Further increases were detected in two parameters after 1 week of therapy with steroids (tPA levels were 6.85+/-2.96 ng/mL and PAI-1 levels were 83.5+/-29.6 ng/mL). There seems to be an increased activity of platelets during an asthma attack. Elevated PAI-1 and tPA levels may also indicate the activated endothelium in asthma. Increases of plasma levels of PAI-1 and tPA after steroid therapy need further investigation because elevated PAI-1 levels enhance airway remodeling.
