The etiology of polyneuropathies varies in the pediatric population, where hereditary or metabolic disorders are far more common than in adults. However, treatable polyneuropathies, also prevalent in these settings, are those to prioritize. Moreover, diagnosing subacute and chronic symptoms in children can be challenging compared to adults. Therefore, selecting the best and most relevant laboratory investigations and paraclinical studies is critical. This taskcan be relatively challenging in countries with limited resources or insurance coverage. This study describe the various types of polyneuropathies found in children and their characteristics and suggest an algorithm for using the best laboratory tests in the context of the Iranian healthcare system.

Clinical Practice Guidelines (CPGs), are "recommendations intended to optimize patient care based on systematic reviews of available evidence and assessment of the benefits and harms of alternative care options". CPGs play an important role in improving the quality of care, reducing the diversity of treatment methods, reducing medical errors, managing health costs and increasing patient safety. This study was conducted with the aim of analyzing the decisions, consequences and policy trends of using CPGs in Iran during the period 2001-2021.

This study was a type of health policy analysis, carried out using analysis of the policy process approach. Data were collected through reviewing policy documents (n=79) and qualitative interviews (n=27). Analysis of policy documents was done using the content analysis method, the software used being Excel software, while for analysis of the interviews the framework analysis method was used, the software being the MAXQDA10 software.

The policy of using CPGs in Iran started in 2001 and has improved over the past two decades. During the period 2016-2021 a total of 836 CPGs (knowledge products) were published, but according to the participants, many of these CPGs or knowledge products did not have the necessary quality and were not used by physicians. The findings of this study also showed that in Iran there is a suitable atmosphere for implementing CPGs and the policies of using them are sound policies; however, there is a huge gap between the development and implementation of CPGs.

Although the process of applying CPGs has improved in Iran, their implementation faces challenges and, thus, they have not been fully implemented. Therefore, there is a need to adopt new standard methods and approaches to improve the quality and reliability of CPGs. Certainly, the support of the government, Ministry of Health and Medical Education, the medical community, insurance organizations and other stakeholders, along with proper collaboration and appropriate policy formulations, are essential to achieve success.

Clinical Practice Guidelines (CPGs) can be adapted to local conditions to prevent any resources from being wasted. Adaptation of CPGs implies a systematic view of developed guidelines through maintaining evidence-based principles in order to find the ones most relevant with patients' conditions and its integration with the cultural and regional requirements of the target population and health system facilities. The main purpose of the study was to describe, interpret and compare different frameworks for adaptation of clinical guidelines and proposing a comprehensive framework for Iran.  

This study was based on a review and comparative analysis of adaptation frameworks of CPGs. Initially, all adaptation frameworks were collected by systematic search in the literature. We searched the following electronic databases: PubMed, Scopus, Trip Database, Science Direct, and Google Scholar. Then, based on the stages of the comparative study, frameworks were described, interpreted, juxtaposed, and compared. Finally, a comprehensive framework for the adaptation of clinical guidelines was proposed by consulting a panel of experts.  

Our literature search resulted in 26 frameworks, of which 18 were potentially relevant. Based on inclusion/exclusion criteria, nine frameworks were included in the study and have been described, interpreted, and compared. The proposed comprehensive framework for the adaptation of clinical guidelines consists of ten main steps.  

The proposed comprehensive framework is an appropriate tool for the adaptation of clinical guidelines in Iran that can be used in other countries. However, further validation of the framework requires case studies and expert consultation to determine its application to the adaptation of clinical guidelines.

The coronavirus disease 2019 (COVID-19) is associated with a variety of physical and emotionaldisorders, and subsequently lower Quality of Life (QOL). This study aimed to investigate the effect of a 2-weekexercise-based pulmonary rehabilitation on clinical characteristics and QOL of severe COVID-19 patients afterdischarge from intensive care unit (ICU).

In this quasi-experimental study, eligible severe COVID-19cases, who had survived and were discharged from ICU were selected using convenience sampling method.Oxygen Saturation ( SpO2), pulse rate, dyspnea, and QOL were evaluated and compared before and after twoweeks of exercise-based pulmonary rehabilitation (PR).

35 cases with the mean age of 57.86 ± 11.73(18-75) years were studied (51.4% female). The mean SpO2 increased from 90.41 ± 3.97 to 95.11 ± 1.96% aftertwo weeks of pulmonary rehabilitation (p<0.0001). In addition, the mean pulse rate (98.97±16.23 to 88.91±14.03pulse/minute; p<0.001) and the mean dyspnea severity (5.6±1.97 to 3.45±1.97; p<0.0001) decreased after twoweeks of intervention. Besides, the mean total QOL and its dimensions, including general health (p<0.0001),physical status (p<0.0001), emotional status (p = 0.036), and social function (p<0.0001) of patients, had signif-icantly increased after intervention.

Based on the findings of this study, it seems that two-weekexercise-based pulmonary rehabilitation could be effective in increasing the SpO2, decreasing dyspnea andpulse rate, and improving the QOL of patients with severe COVID-19 after discharge from ICU.

Enhanced external counterpulsation (EECP) is believed to be a non-invasive treatment for coronary artery disease and angina. The aim of this study was to determine the safety and effectiveness of EECP in refractory angina patients through a systematic reviews and meta-analysis. We conducted a comprehensive search of the literature published on PubMed, Cochrane library, Scopus, ScienceDirect, Trip Database and Google Scholar databases using appropriate keywords and specific strategy with no time limit. Having selected and screened the studies based on the defined inclusion and exclusion criteria and evaluating their quality based on the Cochrane checklist. For the meta-analysis,the Mantel-Haenszel method or the generic Inverse Variance was used. Analyses were done with Review Manager 5.2 software. A number of 299 studies were initially reviewed and finally, seventeen studies were included in the meta-analysis based on the inclusion and exclusion criteria. Also, thirteen outcomes were analyzed and the results of meta-analysis in twelve outcomes including (Systolic Blood Pressure (7 studies), Diastolic Blood Pressure (7 studies), Pulse Pressure (4 studies), Mean Arterial Pressures (4 studies), Heart Rate (6 studies), Angina episodes (7 studies), Walking distance (2 studies),Canadian Cardiovascular Society classification (6 studies), Flow-Mediated Dilation (3 studies), Daily Nitrate Usage (4 studies), Exercise Treadmill Test-Time (2 studies), ST-segment depression (2 studies)demonstrated a significant clinical advantage in the EECP treatment effectiveness in patients with angina. No significant difference was observed regarding EECP usefulness (P = 0.18) in the outcome of brachial artery diameter (2 studies). Based on the meta-analysis, the results indicate the safety and effectiveness of EECP in patients with angina pectoris and indicate the usefulness of this treatment in these patients. In general, the authors believe that the general conclusion in this regard requires some studies with a large sample size and a control group assignment.

The prevalence of ulnar nerve mono neuropathy has increased in recent years. Upper limb in-volvement by ulnar neuropathy results in motor and sensory disability and this disability imposes significantphysical, psychological and financial burdens on patients. We aimed to assess the prevalence and causes ofulnar neuropathy in the Electrodiagnosis clinic of Shohada-e-Tajrish medical center.

In this cross-sectional study we extracted the electronic files of all patients referred to the clinic during 2009-2013. Patients with ulnar neuropathies were selected and required data were obtained. 62 patients with ulnarnerve lesions were included and their data (include age, sex, involved side, cause of lesion, severity and locationof involvement) were analyzed.

Of the 62 patients enrolled, 42(67.7%) were men and 20 (32.3%) werewomen with a mean age of 41.63 years (range: 17-79 years). There was a significant relationship between ageand disease prevalence. The highest prevalence rate of the disease was observed in the 20–39year-old age groupand the lowest in the below 20-year-old age group. Trauma was a more frequent cause than entrapment. El-bow was the most frequent location of injury.

Ulnar neuropathy was more prevalent in young andmiddle-aged individuals than those above 60 years. Considering the potential disability caused by this nervedamage, more attention is needed to evaluate patients and initiate proper treatment and rehabilitation in thoseulnar nerve lesion.

 Carpal tunnel syndrome (CTS) is the most common type of peripheral entrapment neuropathy that occurs in the wrist area in a space called the carpal tunnel. Low-level laser therapy (LLLT) and ultrasound are among the most common methods of physical modalities for treating CTS; the effectiveness of these two methods and superiority of one over the other is not agreed among experts.

 In present systematic review and meta-analysis study, the most important databases including PubMed, Cochrane Library, Scopus, Centre for Reviews and Dissemination, Science Direct, Trip Medical Database, and Google Scholar were searched using appropriate keywords and specific strategies without time limitation to collect data. The collected data was analyzed using meta-analytic method and random effects model. The heterogeneity among studies was examined using I2. The data was analyzed using Review Manager Software.

 From among 108 related studies, 49 cases were entered in the first stage. After the final examination, 6 studies were selected for meta-analysis. The total number of patients in these six studies was 403; 204 subjects were in the LLLT group and 199 subjects were in the ultrasound group. The results of meta-analyses showed that there was no significant difference between these two therapeutic methods in terms of pain relief, symptom severity scale (SSS), functional status scale (FSS), motor latency, sensory latency, handgrip strength, and motor amplitude.

 Based on meta-analyses, there was no significant difference between two LLLT and ultrasound methods; in other words, they had similar effectiveness in improving the condition of patients with CTS. However, the authors believed that arriving at conclusions in this area requires high-quality and large size studies.

The management of Peyronie’s disease (PD) has remained a therapeutic dilemma for physicians and there is no gold standard treatment. In this paper, we decided to investigate the beneficial effect of the intralesional administration of verapamil compared with the intralesional administration of verapamil plus a low-intensity laser (LIL).

Research was activated from May 2016 to May 2018 and a total of 38 men aged 18 years and older completed the investigation. The subjects were randomly divided into 2 groups. Group 1 was composed of 22 patients that were treated only by verapamil (5 mg) plus a sham laser weekly for 6 weeks, and group 2 consisted of 22 patients that received a laser, using the BTL – 6000 HIGH-INTENSITY LASER 12 W machine and the same protocol of intralesional verapamil injection. The visual analogue scale (VAS) was used to evaluate pain during an erection, penile ultrasonography was used to measure plaque size, the penile curvature angle degree was measured using the photographs taken during an erection, and the International Index of Erectile Function questionnaire was used to assess erectile function. The follow-up treatment lasted for nine months, with visits performed in the 3rd and 9th months.

All study parameters decreased significantly after treatment in both arms, but the reduction in pain and penile curvature improvements in combination therapy revealed more significant changes in 3 months (p = .035, p=.032). Nevertheless, these improvements were not seen in the follow-up session after 9 months.

A laser appears to be safe treatment modality in carefully-selected patients with PD. It has moderate efficacy in the short term.

Lumbosacral radiculopathy is a challenging diagnosis, and Electrodiagnostic study (EDX) is a good complementary test for Magnetic Resonance Imaging (MRI). Physical examination, MRI and electrodiagnosis have different diagnostic values in this regard. MRI can provide anatomical evidence and is useful in choosing a treatment process, but it could also have false positive results. In this study, we assessed the correlation of clinical and electrodiagnostic findings in patients with positive MRI findings for S1 radiculopathy. EDX was performed for 87 patients referred with clinical and MRI diagnosis of S1 radiculopathy. The consistency between EDX results, MRI, and clinical findings were evaluated by Pearson chi 2 and odds ratio. Fifty-eight percent of patients had disc protrusion, and 42% had extrusion. Physical examination revealed absent Achilles reflex in 83% and decreased S1 dermatome sensation in 65%. In this study, EDX sensitivity was about 92%. The highest consistency among EDX parameters and physical examination findings was between absent H-reflex and decreased Achilles reflex (OR=6.20, P=0.014), but there was no significant consistency between H-reflex and neither muscular weakness nor SLR test result (P>0.05). There was also no relationship between type of disc herniation in MRI and H reflex. There was correlation between H-reflex abnormalities and absent ankle reflex in patients with unilateral L5-S1 disc herniation in MRI. Results of this study showed that in patients with positive MRI for L5-S1 disc protrusion and S1 nerve root compression, it is still beneficial to perform EDX for selected patients.

In this study, a single-blind and randomized controlled trial (RCT) for assessing the effectiveness of high-power (up to 12 W) laser therapy (HPLT) on patients with patellofemoral pain syndrome (PFPS) was carried out. Forty-four patients were randomly assigned to two treatment groups by generating random numbers with MATLAB 2014b software, where odd and even numbers were attributed to sham laser group (group A) and actual laser group (group B), respectively. Group B patients underwent HPLT with total dose of 300 J/session for 5 consecutive sessions separated by a 2-day interval. On the other hand, sham laser was applied to group A patients. Both groups had the same exercise therapy programs during the study period (3 months). The exercise therapy program included isometric knee exercise for 3 sets per day and 10 times in each set, with duration of 10 seconds per time and straight leg raise for 15 seconds 10 times a day. The group codes of patients were not revealed to subjects and data analyzer until completion of the study. Kujala, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and visual analog scale (VAS) questionnaires were chosen as outcome measures. These questionnaires were completed at three points during the study; at the beginning of the study to obtain the pre-therapy conditions and one month and three months after the start of the study to evaluate post-therapy conditions. Two main analyses were conducted: within-group and between-group analyses. Within-group analyses indicated significant improvements in respect to all measurements where pre-therapy and post-therapy comparisons were conducted in both groups (P < 0.05). On the other hand, between-group comparisons did not reveal any statistically significant functional difference between group A and group B regarding the evaluative criteria (P > 0.05) except for pain VAS (P < 0.05). This study indicated that short-term HPLT accompanied by appropriate exercise regimen significantly decreased pain in patients with PFPS. But it was not recommended as an efficient modality in functional improvement. Also, it was observed that, in the short-term period of study, HPLT was a safe modality.

To evaluate the patients with stroke by Functional Independence Measure (FIM) scale, at the times of admission to hospital, discharge, and six-month poststroke, and to determine the level of improvement in patients after rehabilitative procedures.
A total number of 108 patients with stroke entered the study who were admitted to neurology ward. They all received rehabilitation consultation, and occupational and physical therapies were prescribed for them. Finally, their functional status was evaluated by FIM scale.
The median (and range) of FIM scores were 86 (15-119), 102 (16-123) and 119 (17-126) at admission, discharge, and after six-month follow-up, respectively. Our observations showed a significant improvement in FIM scores (P The study showed that the FIM is a valid tool for evaluation of patients with stroke, their follow-up and tracking the disease course. Moreover, we concluded that patients with stroke make a significant improvement in their functional status overtime. The exact effect of rehabilitative procedures and comparison with no treatment, must be assessed in separate studies.

To study the effects of Polarized Polychromatic Noncoherent Light (Bioptron) therapy on patients with carpal tunnel syndrome (CTS). This study was designed as a randomized clinical trial. Forty four patients with mild or moderate CTS (confirmed by clinical and electrodiagnostic studies) were assigned randomly into two groups (intervention and control goups). At the beginning of the study, both groups received wrist splinting for 8 weeks. Bioptron light was applied for the intervention group (eight sessions, for 3/weeks). Bioptron was applied perpendicularly to the wrist from a 10 centimeters distance. Pain severity and electrodiagnostic measurements were compared from before to 8 weeks after initiating each treatment. Eight weeks after starting the treatments, the mean of pain severity based on Visual Analogue Scale (VAS) scores decreased significantly in both groups. Median Sensory Nerve Action Potential (SNAP) latency decreased significantly in both groups. However, other electrophysiological findings (median Compound Motor Action Potential (CMAP) latency and amplitude, also SNAP amplitude) did not change after the therapy in both groups. There was no meaningful difference between two groups regarding the changes in the pain severity. Bioptron with the above mentioned parameters led to therapeutic effects equal to splinting alone in patients with carpal tunnel syndrome. However, applying Bioptron with different therapeutic protocols and light parameters other than used in this study, perhaps longer duration of therapy and long term assessment may reveal different results favoring Bioptron therapy.

Carpal Tunnel Syndrome (CTS) is the most common type of entrapment neuropathy. Conservative therapy is usually considered as the first step in the management of CTS. Low Level Laser Therapy (LLLT) is among the new physical modalities, which has shown therapeutic effects in CTS. The aim of the present study was to compare the effects of applying LASER and splinting together with splinting alone in patients with CTS. Fifty patients with mild and moderate CTS who met inclusion criteria were included in this study. The disease was confirmed by electrodiagnostic study (EDx) and clinical findings. Patients were randomly divided into 3 groups. Group A received LLLT and splinting. Group B received sham LLLT+ splinting and group C received only splints. Group A received LLLT (50 mw and 880nm with total dose of 6 joule/cm2). Clinical and EDx parameters were evaluated before and after treatment (3 weeks and 2 months later). Electrophysiologic parameters and clinical findings including CTS provocative tests, Symptoms severity score (SSS), Functional Severity Score (FSS) and Visual Analogue Score (VAS) were improved in all three groups at 3 weeks and 2 months after treatment. No significant changes were noticed between the three groups regarding clinical and EDX parameters. We found no superiority in applying Low Intensity Laser accompanying splinting to traditional treatment which means splinting alone in patients with CTS. However, future studies investigating LLLT with parameters other than the one used in this study may reveal different results in favor of LLLT.

The prototypical injury of the median nerve at the wrist is either an acute or chronic compressive lesion referred to as carpal tunnel syndrome (CTS). The present study was conducted to determine the individual risk factors for carpal tunnel syndrome (CTS) in subjects referred to Department of Physical Medicine and Rehabilitation of Shoha-Tajrish Hospital.

A cross sectional study was performed on 1000 patients with upper limbs pain, among whom 250 cases (34 men and 216 women) aged 18-69 years were diagnosed to have CTS on basis of clinical history and electrodiagnostic criteria. Following factors were compared between CTS patients and controls: body mass index (BMI), wrist A-P/M-L diameter, occupation, average daily hours of computer use, history of steroid use, family history, diabetes mellitus, thyroid disease, chronic heart failure, renal failure, history of wrist and distal radius fracture, smoking, alcohol drinking, use of OCP, history of hysterectomy, pregnancy, menopause, radiculopathy, associated rheumatologic disease and other soft tissue rheumatism.

The frequency of CTS among the studied subjects was 25%. Mean BMI was higher in patients with CTS in both genders (p<0.000), but increasing of BMI excess 30, didn’t raise the risk of CTS (NS). Wrist (A-P/M-L) dimension was found to be higher in CTS group (p<0.05). Steroid use was 2% in control group and 8% in CTS group (p<0.05). Colleś fracture was only reported among 2.4% of CTS subjects (p<0.05). Diabetes mellitus was 4% in controls versus 11.2% in CTS group (p<0.05). Severe CTS was associated with the following factors: BMI≥25, WD>0.7 and duration>6 month, female gender, and diabetes mellitus and Colleś fracture, in both genders.

The prevalence of syndrome was quite high, therefore, supplementary investigation should be performed. The wrist A-P/M-L dimension was higher in both genders of CTS group, thus we suggest wrist A-P/M-L dimension as a risk factor for CTS, however it could be explained as a consequence of CTS pathology.
