RESUMEN

OBJECTIVE: Endogenous melatonin is produced from tryptophan which is an essential amino acid. Besides its role in the regulation of sleep patterns, melatonin has anti-inflammatory effects. In this case-control study, we aimed to compare tryptophan and melatonin levels and their relationship with the inflammatory response, specifically serum interleukin-1, interleukin-6, and c-reactive protein levels following major abdominal surgery in patients with food restriction and who receive parenteral nutritional therapy. METHODS: We enrolled 40 patients between the ages of 18 and 65 years in the study. We collected blood and urine samples 48 h before the operation and on postoperative days 1, 3, and 5. RESULTS AND CONCLUSION: The tryptophan levels in the experimental group were higher than in the control group but failed to reach any statistical difference. Melatonin levels were increased in both groups following the surgery compared with preoperative levels. The increase in the experimental group was statistically different 3 days after the surgery. The difference in the level of interleukin-1 between the control and the experimental groups was greatest on postoperative day 3. On postoperative day 3, the interleukin-6 level in the treatment group was slightly higher than in the control group. We did not find any difference in the levels of c-reactive protein between the groups. As a result, the levels of tryptophan and melatonin were increased in the parenteral nutrition group, irrespective of the postoperative inflammatory response.

RESUMEN

Low anterior resection, performing total mesorectal excision with appropriate pelvic dissection to prevent local recurrence, is probably the most challenging type of surgery in colorectal surgery, especially in a narrow pelvis. In this study, we aimed to predict the operation difficulty of rectal cancer by comparing the operation time with 2D and 3D pelvimetry. Sixty-six patients who underwent total mesorectal excision after neoadjuvant chemoradiotherapy due to primary rectal cancer located in the middle and lower rectum (10 cm from the anus) were included in the study. Surgery notes were reviewed and data on demographic factors, tumor stage, duration of surgery, and types of surgery were collected, as well as pelvimetric parameters. All protocols had 2D T2-weighted sequences in 3 planes (axial, sagittal, and coronal). Pelvimetric measurements were made by measuring 8 pelvic lengths and 2 angles. Pelvis and tumor volume were measured by manual margin monitoring. In each slice, both pelvis and tumor boundaries were manually drawn individually in the sagittal plane. Pelvis and tumor volumes were calculated from the set of adjacent images by summing slice thickness and products of area measurements within the pelvis and tumor boundaries. In our results, no correlation was observed with operation time, including pelvic volume. Exception for this were interacetabular distance and tumor volume. In the regression test, the only parameter that correlated with the operation time was tumor volume. In conclusion, we believe that tumor volumetric calculations may be useful in predicting difficult distal rectal carcinoma surgeries.

RESUMEN

OBJECTIVES: Pregabalin (PGB) is used in drug-resistant epilepsy. Also, it has analgesic effects in painful syndromes. Depression and anxiety are commonly seen in epilepsy and neuropathic pain patients. PGB is often combined with anxiolytics and antidepressants. We aimed to investigate the antidepressant and anxiolytic effects of PGB and compare its effects with those of antidepressant and anxiolytic drugs and their combined use. METHODS: Wistar Albino rats were used, and PGB (5, 10, 20, and 40 mg/kg), amitriptylin (AMT), fluoxetine (FLX), ketamine (KET), and diazepam (DZM), as well as combinations of PGB (20 mg/kg) with AMT, FLX, KET, and DZM, were administered. Elevated plus maze, forced swimming, and locomotor activity tests were performed. RESULTS: In the elevated plus maze, PGB10, 20, 40, AMT, FLX, and DZM increased open arm time. The PGB20+FLX combination increased compared to PGB20. In forced swimming, PGB doses increased immobility time. AMT, FLX, DZM, and KET decreased compared to control and PGB doses. Other combinations of PGB20 reversed immobility time, except FLX. In locomotor activity, PGB20, AMT, KET, and DZM decreased distance. CONCLUSION: PGB had a depressant effect in all doses and a dose-dependently anxiolytic effect. In combinations of PGB with AMT, KET, and DZM, it reversed their antidepressant effects. We assumed FLX could be preferred instead of AMT in patients using PGB. When PGB is used in combination, drug interactions should be considered. These results are also very remarkable in terms of pharmacoeconomics.

RESUMEN

Objectives: In this study, we aimed to compare the efficacy of ultrasonography (US) and steroid phonophoresis (PH) treatments in patients with idiopathic carpal tunnel syndrome (CTS). Patients and methods: Between January 2013 and May 2015, a total of 46 hands of 27 patients (5 males, 22 females; mean age: 47.3+13.7 years; range, 23 to 67 years) with idiopathic mild/moderate CTS without tenor atrophy or spontaneous activity in abductor pollicis brevis were included. The patients were randomly divided into three groups. The first group was ultrasound (US) group, the second group was PH group, and the third group was placebo US group. Continuous US with a frequency of 1 MHz, an intensity of 1.0 W/cm2 was used in the US and the PH groups. The PH group received 0.1% dexamethasone. Placebo group received a frequency of 0 MHz, an intensity of 0 W/cm2 US. Treatments were administered for five days a week, a total of 10 sessions. All patients also wore night splints during treatment. The Visual Analog Scale (VAS), Boston Carpal Tunnel Questionnaire consisting of two parts, namely the Symptom Severity Scale and Functional Status Scale), grip strength, and electroneurophysiological evaluations were compared before the treatment, after the treatment, and three months later. Results: All clinical parameters improved in all groups after treatment and at three months, except for the grip strength. Recovery in the sensory nerve conduction velocity between palm and wrist was seen in US group at three months after the treatment; however, recovery in the sensory nerve distal latency between the second finger and palm was seen in PH and placebo groups after treatment and at three months after the treatment. Conclusion: The results of this study suggest that splinting therapy combined with steroid PH, placebo or continuous US is effective for both clinical and electroneurophysiological improvement; however, electroneurophysiological improvement is limited.

RESUMEN

Acute mesenteric ischemia is a surgical emergency with high morbidity and mortality rates. Therefore, it is important to determine the prognosis for this disease. In the present study, we aimed to compare the prediction accuracy of 3 scoring systems: Acute physiology and chronic health evaluation II, sequential organ failure assessment score and simplified acute physiology score II (SAPS II). The retrospective cohort study was conducted in a university hospital. Eighty-two acute mesenteric ischemia patients were evaluated retrospectively. The mortality prediction abilities of the scoring systems were evaluated by comparing the prediction rates of > 10%, 30% and 50% and the actual mortality among survivors and non-survivors in pairs. Predicted mortality rates among survivors and non-survivors differed among the 3 classification systems. The mortality estimates of the SAPS II were closer to the actual mortality rates. Analysis of the estimated mortality rates as mortality risk limits showed that acute physiology and chronic health evaluation II was superior to sequential organ failure assessment score and SAPS II in estimating mortality rates, whereas SAPS II was more successful in detecting survivors. The estimated mortality rates of the 3 rating systems, the estimated mortality rates were higher in the non-survivor group than in the survivor group. The accuracy of the SAPS II in determining prognosis was relatively better.

RESUMEN

Euterpe oleracea (EO) includes a large number of polyphenolic compounds such as phenolics, flavonoids, and anthocyanins that have antioxidant activities. E. oleracea was suggested to ease the oxidative stress and inflammation in brain cells. Our aim was to analyze the effects of E. oleracea on learning and memory. Seventy-two (250 ± 25 g) male Wistar albino rats were used for this study. The groups consisted of control, EO100 mg/kg, EO300 mg/kg, scopolamine 1.5 mg/kg, mecamylamine 7.5 mg/kg, combinations of scopolamine with EO100 mg/kg, EO300 mg/kg, and rivastigmine 1.5 mg/kg; and mecamylamine combined with EO100 mg/kg. Before the start of the study, E. oleracea doses were provided once a day for a period of 15 days and for a 6-day experimental period. Thirty minutes after intraperitoneal scopolamine and mecamylamine injections, gastrogavage was applied to each group. Ninety minutes after the drug treatments, locomotor activity and Morris water maze tests were performed. Rats were killed and each hippocampus was used for the quantification of acetylcholine (Ach). Statistical analyses were calculated using one-way and two-way analyses of variance (ANOVA), and a value of P < .05 was considered significant. In groups EO100 mg/kg and EO300 mg/kg the results did not show any significant changes on learning and memory compared with the control group. Mecamylamine and scopolamine enhanced the latency for the escape platform, and decreased the time spent in escape platform quadrant when the memory tests were applied in reference to the control value of P < .05. Scopolamine and mecamylamine combinations of EO100 mg/kg, EO300 mg/kg, and rivastigmine were proven to improve the memory. There was significant difference between the first and fifth days of the learning tests in all the groups, but no significant difference occurred between the groups. Ach levels in hippocampi supported all memory tests. We suggest that E. oleracea made no alterations on learning and memory, but still improved nicotinic and muscarinic receptor-mediated and impaired memory just as rivastigmine.

RESUMEN

OBJECTIVES: Acute exposure to ultraviolet B radiation can cause photokeratitis. Retinol palmitate (RP) is known to have antioxidant properties and improve corneal healing. The aim of this study was to evaluate the effect of topical RP against phototoxic keratitis in rats. METHODS: A total of 14 male Wistar Albino rats were exposed to 1 J/cm2 dose of 311 nm ultraviolet B radiation. The subjects were then divided into 4 study groups using the right and left eye: The RP-5 group (n=7) received topical 250 IU/g RP ointment and the Sham-5 group (n=7) received only the vehicle base component of the ointment 5 minutes after the exposure. The RP-120 group (n=7) received topical RP and the Sham-120 group (n=7) received the vehicle alone 120 minutes after the exposure. The eyes were enucleated 24 hours after the exposure and stained with hematoxylin and eosin for histopathological examination and a terminal deoxynucleotidyl transferase dUTP nick end labeling assay to test for apoptosis. RESULTS: There was no statistically significant difference between the mean corneal epithelial thickness of the RP-5 group and the Sham-5 group (p=0.369). Furthermore, there was no significant difference between the RP-120 and the Sham-120 groups (p=0.765). The timing of the administration of RP resulted in no significant difference in the mean corneal epithelial thickness (p=0.608). Apoptotic cell count scores were not significantly different between corneas that received RP and those who received only the vehicle (p=0.530, p=0.107). CONCLUSION: Topical administration of a single dose of RP was not superior to the use of the vehicle base alone in a photokeratitis model produced using 1 J/cm2 of narrowband ultraviolet radiation in rats.

RESUMEN

AIM: Studies have shown that the causes and methods of suicides differ among young and old individuals; consequently, it is important to identify the subgroups that are at high risk for suicide to aid in suicide prevention. The present study compared the causes and methods of suicides between 2002 and 2013 among older adults aged 65-69 years, 70-74 years and ≥75 years by completed crude suicide rate and sex. METHODS: Data detailing sex, the causes and methods of completed suicides in older adults aged 65-69 years, 70-74 years and ≥75 years that occurred between 2002 and 2013 were drawn from the Turkish Statistical Institute. RESULTS: In all age groups, crude suicide rates were threefold more frequent among men than among women. In both sexes, the most frequent suicide cause was mental illness. In the group aged 65-69 years, the most common cause of suicide was financial difficulty for men and marital conflict for women. The most frequent suicide method among older adults of both sexes was hanging. In all age groups, firearms use was more common among men and jumping from a high place was more common among women. CONCLUSION: The present findings suggest that the most common suicide cause in both sexes and in all age groups was mental illness in Turkey. To prevent suicidal behavior in older adults,; it is important to diagnose mental disorders, such as mood disorders and substance abuse, and to treat them quickly.

RESUMEN

OBJECTIVE: Pregabalin (PGB) is a compound used in the treatment of epilepsy, anxiety, and neuropathic pain. Experimental data also indicate that PGB can reduce inflammatory pain. We aimed to investigate the anti-inflammatory effects of PGB on carrageenan (CAR)-induced paw edema and its effects on tumor necrosis factor-α (TNF-α) and interleukine-1ß (IL-1ß) acting as acute phase cytokines in inflammation, and anti-inflammatory cytokine IL-10, in rats. MATERIALS AND METHODS: Single doses of PGB 30, 50, and 100 mg/kg and indomethacin (INDO) 5 mg/kg in the treatment groups and saline in the control group were injected once intraperitoneally prior to administration of 100 µl of 1% CAR into the right hind paw of the rats. The paw thickness was measured using gauge calipers (Vernier calipers) before (0 hour) and every hour afterwards for 6 hours following the inflammation induction. The cytokine levels in the blood serum obtained intracardiacally were determined after 6 hours using the enzyme-linked immunosorbent assay method. p<0.05 was considered statistically significant. RESULTS: There was no significant difference between the 0 and 6th hour considering the paw thickness in all groups, except in the CAR group. CAR significantly increased the paw thickness at 6 hours compared to the 0 hour. All doses of PGB and INDO significantly reduced the paw thickness after 6 hours compared to the CAR group. The TNF-α and IL-1ß levels in the PGB and INDO groups were comparable to the control group, whereas in the CAR group, these levels were increased. The IL-10 level was enhanced in the PGB 50 mg/kg and INDO groups. CONCLUSION: It was observed that all doses of PGB exerted anti-inflammatory-like effects comparable to INDO, supported by their effects on the levels of cytokines.

RESUMEN

The aim of this study is to propose a new pairwise multiple comparison adjustment procedure based on Genz's numerical computation of probabilities from a multivariate normal distribution. This method is applied to the results of two-sample log-rank and weighted log-rank statistics where the survival data contained right-censored observations. We conducted Monte Carlo simulation studies not only to evaluate the familywise error rate and power of the proposed procedure but also to compare the procedure with conventional methods. The proposed method is also applied to the data set consisting of 815 patients on a liver transplant waiting list from 1990 to 1999. It was found that the proposed method can control the type I error rate, and it yielded similar power as Tukey's and high power with respect to the other adjustment procedures. In addition to having a straightforward formula, it is easy to implement.

RESUMEN

BACKGROUND: This study compared the predictive accuracy of four scoring systems, namely Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential Organ Failure Assessment (SOFA), Simplified Acute Physiology Score II (SAPS II), and Mortality in Emergency Department (MEDS), for estimating prognosis in patients with necrotizing fasciitis. METHODS: Seventy-four patients who presented with necrotizing fasciitis were retrospectively examined. The ability of the scoring systems to predict mortality was assessed by comparing the estimated mortality rates in mortality groups (survivors/non-survivors), and mortality rates among survivors and non-survivors with an estimated mortality of >10%, 30%, and 50% in the scoring systems were compared in pairs. RESULTS: Estimated mortality rates in the survivor and non-survivor groups were different for all the scoring systems. The estimated mortality rates of APACHE II and SAPS II were much closer to the actual mortality rates than the other two scoring systems. When the predicted mortality rates were analyzed as limits for a mortality risk, the predicted mortality rate by APACHE II was superior to that by SAPS II. CONCLUSION: The studied scoring systems had significantly higher predicted mortality rates in non-survivors than in survivors; however, they all underestimated the mortality rate. APACHE II and SAPS II were relatively superior for estimating mortality in patients with necrotizing fasciitis. APACHE II rather than the other scoring systems should be currently used.

RESUMEN

OBJECTIVE: The aim of the study is to increase the participation level of women in screening programs by increasing the level of knowledge about early diagnosis and screening methods for breast cancer (BC). MATERIALS AND METHODS: This was a pretest-posttest one group design study held in Eskisehir Osmangazi University, Turkey. The sample consisted of 405 women in all departments of the University. Data were collected using socio-demographic forms and questionnaires. Training about BC was provided for participants. The questionnaire used prior to the training to measure levels of knowledge about BC was re-administered 3 weeks after the training. RESULTS: The women were most commonly aware of the breast self-examination (68.1%). The ratio of women who had had mammography in the previous year was 11.4%. The BC knowledge level significantly increased after the training (p=0.001). CONCLUSION: This study determined that the level of knowledge about BC in terms of early detection and screening was low and that the percentage of participation in screening was also low.

RESUMEN

Disruption of nocturnal sleep in an intensive care unit may remarkably affect production of melatonin, which is also known to have anti-inflammatory properties. In the present study, we aimed to investigate the effect of sleep quality on melatonin levels and inflammation after surgery. Thus, we compared the patients, who were screened in the side-rooms where the lights were dimmed and noise levels were reduced, with the patients who received usual care. Preoperative and postoperative urine 6-sulphatoxymelatonin, serum interleukin-1 (IL-1), interleukin-6 (IL-6), and c-reactive protein (CRP) levels were measured and data on sleep quality was collected using the Richards-Campbell Sleep Questionnaire. Postoperative CRP and IL-6 levels were greater in the control group than in the experimental group, whereas postoperative 24 h melatonin levels were greater than preoperative levels and the difference was steeper in the experimental group in concordance with sleep quality scores. Thus, the regulation of light and noise in ICUs may help the recovery after major surgeries in patients, potentially by increasing melatonin production, which has anti-inflammatory properties.

RESUMEN

AIM: Cerebral vasospasm following subarachnoid hemorrhage (SAH) is the most important complication that effects the mortality and morbidity of patients with intracranial aneurysm. Today, the mechanisms of vasospasm are not understood in spite of experimental and clinical researches. The aim of our study was to investigate the effects of curcumin on vasospasm following SAH. MATERIAL AND METHODS: In this study, 64 rats (200-250 g weight) were divided into 7 groups. Group 1: having no treatment after SAH; Group 2: treatment with nimodipine after SAH; Group 3: treatment with nicorandil after SAH; Group 4: treatment with sildenafil citrate after SAH; Group 5: treatment with 150 mg/kg curcumin after SAH; Group 6: treatment with 300 mg/kg curcumin after SAH, Group 7: treatment with 600 mg/kg curcumin after SAH. The experimental SAH was induced by injection of autologous blood into the cisterna magna. After medical treatment, in the first hour, blood was taken for quantified the levels of TNF-α, IL-1ß and IL-6. Then, cerebrum and cerebellum were removed for analysis. Basilar artery luminal diameter was measured and apoptotic cell count was performed with tissue samples. RESULTS: Histopathological findings showed that, in sufficient dose, curcumin dilated the basilar artery beside anti-oxidant effect. CONCLUSION: Curcumin can be used for the treatment of vasospasm as a new medical drug.

RESUMEN

OBJECTIVE: To analyse suicides occurring in Turkey between 1990 and 2010 according to sex, age, reason and method. METHODS: Data concerning suicides occurring in Turkey between 1990 and 2010 were obtained from annual records published by the Turkish Statistical Institute. Data were analysed according to sex, age, reason for suicide and suicide method. RESULTS: The crude suicide rate was 2.42 per 100 000 population in 1990 and 4.02 per 100 000 population in 2010. The highest number of suicides was seen in those aged 15-24 years. In this age group, the number of suicides in females was significantly higher than in males. The most common suicide method in Turkey was hanging. Men used firearms more frequently than women. All the reasons for suicide occurred in a higher number of males than females; however, the difference between males and females was more significant for economic problems, relationship problems and educational failure. The leading reason for suicide in females was relationship problems. CONCLUSION: Detecting population subgroups with a high suicide risk and obtaining regional demographic data are of great importance for future studies on suicide prevention.

RESUMEN

BACKGROUND: The aim of our study was to evaluate the effect of lactate level (LL) and shock index (SI) on the outcome in nontraumatic hypotensive patients in the emergency department, and also to show the significance of the combined usage of these two parameters. METHODS: This is a prospective, observational study. Elevated and normal LL (ELL and NLL), elevated and normal SI (ESI and NSI), and a combination of these two parameters (lactate-SI group 1: ELL and ESI, lactate-SI group 2: ELL or ESI, and lactate-SI group 3: NLL and NSI) were evaluated for primary (mortality) and secondary outcome measures. RESULTS: A total of 131 patients who fulfilled the inclusion criteria were analysed. Of the patients with ELL, 34.78% were mechanically ventilated (P<0.001), 31.88% received vasoactive drugs (P<0.001), and 68.1% were hospitalized (P<0.01). The mortality rate among patients with ELL was 50.72% (P<0.001). Of the patients with ESI, 39.42% died (P<0.01). Use of mechanical ventilation in the emergency department was higher in lactate-SI group 1 [36.1%, P<0.0001, sensitivity: 100.0%, negative predictive value (NPV): 100.0%]. Vasoactive drug use was higher in lactate-SI group 1 (32.8%, P<0.0001, sensitivity: 100.0%, NPV: 100.0%). Lactate-SI group 1 showed a higher hospitalization rate (67.8%, P>0.05). In-hospital mortality in lactate-SI group 1 was higher (54.1%, P<0.0001, sensitivity: 100.0%, NPV: 100.0%). CONCLUSION: The combination of both parameters is effective in predicting these outcome measures with higher sensitivities and NPVs. Further studies on the subject are required.

RESUMEN

OBJECTIVES: The aim of the present study was to evaluate the symptomatic effects of glucosamine sulphate (GS) in comparison to the exercise therapy, as well effects on Magnetic Resonance Imaging (MRI) findings of cartilage loss in patients with knee osteoarthritis (OA). MATERIALS AND METHODS: Seventy patients with a diagnosis of knee OA were randomly divided into two groups. First group of patients (n=40) were treated with 1500 mg/day oral glucosamine sulphate and the second group (n=30) performed a home exercise program for a period of 6 months. RESULTS: Compared with baseline, significant improvements were observed in the visual analogue scale pain scores and the Western Ontario and McMaster Universities osteoarthritis index and 20-min walking time in both groups (p< 0.001); there were no significant differences between the two treatment groups. Upon the evaluation of joint cartilage thickness by MRI, an improvement was evident in only in the area of medial femoral condyle of patients who had performed a home exercise program (p< 0.05). CONCLUSION: The results of the present study suggest that both oral GS treatment and exercise therapy are efficient in the symptomatic treatment of patients with knee OA. However, exercise therapy found to have a better chondroprotective effect than oral GS treatment in this patient population.

RESUMEN

Despite the association of several miRNAs with bladder cancer, little is known about the miRNAs' regulatory networks. In this study, we aimed to construct potential networks of bladder-cancer-related miRNAs and their known target genes using miRNA expression profiling and bioinformatics tools and to investigate potential key molecules that might play roles in bladder cancer regulatory networks. Global miRNA expression profiles were obtained using microarray followed by RT-qPCR validation using two randomly selected miRNAs. Known targets of deregulated miRNAs were utilized using DIANA-TarBase database v6.0. The incorporation of deregulated miRNAs and target genes into KEGG pathways were utilized using DIANA-mirPath software. To construct potential miRNA regulatory networks, the overlapping parts of three selected KEGG pathways were visualized by Cytoscape software. We finally gained 19 deregulated miRNAs, including 5 ups- and 14 down regulated in 27 bladder-cancer tissue samples and 8 normal urothelial tissue samples. The enrichment results of deregulated miRNAs and known target genes showed that most pathways were related to cancer or cell signaling pathways. We determined the hub CDK6, BCL2, E2F3, PTEN, MYC, RB, and ERBB3 target genes and hub hsa-let-7c, hsa-miR-195-5p, hsa-miR-141-3p, hsa-miR-26a-5p, hsa-miR-23b-3p, and hsa-miR-125b-5p miRNAs of the constructed networks. These findings provide new insights into the bladder cancer regulatory networks and give us a hypothesis that hsa-let-7c, hsa-miR-195-5p, and hsa-miR-125b-5p, along with CDK4 and CDK6 genes might exist in the same bladder cancer pathway. Particularly, hub miRNAs and genes might be potential biomarkers for bladder cancer clinics.

RESUMEN

OBJECTIVE: The aim of this placebo-controlled study was to evaluate the effects of pulsed and continuous ultrasound treatments combined with splint therapy on patients with mild and moderate idiopathic carpal tunnel syndrome. METHODS: The study included 46 carpal tunnel syndrome patients who were randomly divided into 3 groups. The first group (n = 15) received a 0 W/cm2 ultrasound treatment (placebo); the second group (n = 16) received a 1.0 W/cm2 continuous ultrasound treatment and the third group (n = 15) received a 1.0 W/cm2 1:4 pulsed ultrasound treatment 5 days a week for a total of 15 sessions. All patients also wore night splints during treatment period. Pre-treatment and post-treatment Visual Analogue Scale, Symptom Severity Scale and Functional Status Scale scores, median nerve motor conduction velocity and distal latency and sensory conduction velocities of the median nerve in the 2nd finger and palm were compared. Clinicaltrials.gov: NCT02054247. RESULTS: There were significant improvements in all groups in terms of the post-treatment Functional Status Scale score (p<0.05 for all groups), Symptom Severity Scale score (first group: p<0.05, second group: p<0.01, third group: p<0.001) and Visual Analogue Scale score (first and third groups: p<0.01, second group: p<0.001). Sensory conduction velocities improved in the second and third groups (p<0.01). Distal latency in the 2nd finger showed improvement only in the third group (p<0.01) and action potential latency in the palm improved only in the second group (p<0.05). CONCLUSION: The results of this study suggest that splinting therapy combined with placebo and pulsed or continuous ultrasound have similar effects on clinical improvement. Patients treated with continuous and pulsed ultrasound showed electrophysiological improvement; however, the results were not superior to those of the placebo.
