Objective: The aim of this study was to evaluate the patient's morbidity and postsurgical complications after treatment of palatal donor sites after free gingival graft harvesting using leucocyte- and platelet-rich fibrin (L-PRF) membranes or a hemostatic agent with oxidized and regenerated cellulose. Method and materials: Forty-two palatal donor sites after free gingival graft harvesting in 42 patients were randomly assigned to experimental (L-PRF membrane) or control procedure (hemostatic agent). The primary outcome was postoperative pain related to the wound located at the palatal area, and the secondary outcomes were postoperative discomfort, inability to chew, postoperative stress, surgical chair time, thickness of the palatal fibromucosa, and thickness of the free gingival graft. The patient-reported outcome measures were recorded after 1 week. Results: After 1 week, a statistically significant difference was found between groups in terms of postoperative stress (P = .008). No statistically significant differences in terms of postoperative pain (P = .326), patient discomfort (P = .509), inability to chew (P = .936), or surgical chair time (P = .932) were recorded between the test and the control group. No statistically significant differences were recorded in terms of thickness of the palatal fibromucosa (P = .647) and thickness of the free gingival graft (P = .756) between groups. Postsurgical wound healing complications (ie, necrosis or infections) were not observed in both groups. Conclusion: Within their limitations, the present outcomes indicated that the application of L-PRF membrane at palatal donor sites after FGG harvesting did not produce significant advantages for the patients.

Objective: To evaluate the focus of pediatricians’ gaze during the heel prick of neonates. Methods: Prospective study in which pediatricians wearing eye tracker glasses evaluated neonatal pain before/after a heel prtick. Pediatricians scored the pain they perceived in the neonate in a verbal analogue numerical scale (0=no pain; 10=maximum pain). The outcomes measured were number and time of visual fixations in upper face, lower face, and hands, in two 10-second periods, before (pre) and after the puncture (post). These outcomes were compared between the periods, and according to pediatricians’ pain perception: absent/mild (score: 0–5) and moderate/intense (score: 6–10). Results: 24 pediatricians (31 years old, 92% female) evaluated 24 neonates. The median score attributed to neonatal pain during the heel prick was 7.0 (Interquartile range: 5–8). Compared to pre-, in the post-periods, more pediatricians fixed their gaze on the lower face (63 vs. 92%; p=0.036) and the number of visual fixations was greater on the lower face (2.0 vs. 5.0; p=0.018). There was no difference in the number and time of visual fixations according to the intensity of pain. Conclusions: At bedside, pediatricians change their focus of attention on the neonatal face after a painful procedure, focusing mainly on the lower part of the face. [ABSTRACT FROM AUTHOR]

Background: Oral cancer is one of the most painful cancer types, and is often refractory to existing analgesics. Oral cancer patients frequently develop a tolerance to opioids, the mainstay of current cancer pain therapy, leaving them with limited therapeutic options. Thus, there is a great need to identify molecular mechanisms driving oral cancer pain in an effort to develop new analgesics. Previous reports demonstrate that oral cancer patients experience intense mechanical pain and pain in function. To date, no studies have examined thermal pain in oral cancer patients or the role that alcohol consumption plays in oral cancer pain. This study aims to evaluate patient-reported pain levels and thermal allodynia, potential molecular mechanisms mediating thermal allodynia, and the effects of alcohol consumption on patient-perceived pain. Methods: This study evaluated human oral squamous cell carcinoma (OSCC) cell lines for their ability to activate thermosensitive channels in vitro and validated these findings in a rat model of orofacial pain. Patient-reported pain in a south Texas OSCC cohort (n = 27) was examined using a visual analog scale (VAS). Covariant analysis examined variables such as tobacco and alcohol consumption, ethnicity, gender, and cancer stage. Results: We determined that OSCC secretes factors that stimulate both the Transient Receptor Potential Ankyrin type 1 channel (TRPA1; noxious cold sensor) and the Transient Receptor Potential Vanilloid type 1 channel (TRPV1; noxious heat sensor) in vitro and that OSCC-secreted factors sensitize TRPV1 nociceptors in vivo. These findings were validated in this cohort, in which allodynia to cold and heat were reported. Notably, subjects that reported regular alcohol consumption also reported lower pain scores for every type of pain tested, with significantly reduced cold-induced pain, aching pain, and burning pain. Conclusion: Oral cancer patients experience multiple types of cancer pain, including thermal allodynia. Alcohol consumption correlates with reduced OSCC pain and reduced thermal allodynia, which may be mediated by TRPA1 and TRPV1. Hence, reduced pain in these patients may contribute to a delay in seeking care, and thus a delay in early detection and treatment. [ABSTRACT FROM AUTHOR]

Objective. To analyze the clinical approbation of the Russian-language version of the SRS-22 questionnaire for adult patients with scoliosis, to assess its reliability using Cronbach’s alpha criterion for internal consistency, and to determine its efficacy and specificity by correlation match- ing with the ODI results and numerical pain scale’s scores. Material and Methods. A survey of 196 patients aged over 18 years with spinal pathology was carried out using the SRS-22 questionnaire. The questionnaire results were compared with the Oswestry Disability Index and numerical pain scale. Cronbach’s alpha reliability index was used to measure internal consistency of the questionnaire. Variation statistics method was used: calculation of the arithmetic mean and the mean deviation, Pearson correlation coefficient with evaluation according to the Chaddock scale. To evaluate consistency of mean differences, the Student t-test with determination of statistical consistency index was used. Results. The Cronbach’s alpha reliability index within domains in adult scoliosis patients was more than 0.7 and demonstrated satisfac- tory internal consistency of the questionnaire. Comparative analysis of SRS-22 scores revealed that scores of deformity-specific domains (Function, Self-image, Mental health, Satisfaction with management) were higher in patients with scoliosis. High correlation between the SRS-22 Function domain and the ODI was detected. Correlation between the SRS-22 Pain domain and numerical pain scale was moderate. Conclusion. The proposed Russian version of the SRS-22 questionnaire is reliable, specific and effective tool for self-assessment of health status in adult scoliosis patients and can be further used to evaluate the results of surgical treatment.

Background: Knee medial collateral ligament (MCL) sprain is common in athletes, which keeps them away from trainings. Platelet-rich plasma (PRP) injection is used as an adjunct for treatment of musculoskeletal injuries. This study was supposed to define effect of PRP injection on high-grade MCL sprain healing, in comparison to rehabilitation alone. Materials and Methods: This study was performed on 46 healthy athletes with high-grade MCL sprains who came to sports medicine clinic of Taleghani Hospital, Tehran over a one-year period (2017-2018). In first visit injury grade, its location, baseline pain, Lysholm score and joint stability was determined. Participants randomly allocated to 2 groups (n=23), "group A" had 12-week functional rehabilitation and "group B" had the same rehabilitation plus a single PRP injection. At 4-week intervals valgus stress testing, pain and Lysholm scores was reassessed. The scores of 4th, 8th and 12th weeks was compared to the baseline scores. Results: Mean baseline pain score in control and intervention group was 5.09±0.949 and 5.26±0.810 respectively that in the fourth week of study reduced to 1.30±0.765 and 2.43±0.507 (p<0.001). In intervention group, fourth week pain was significantly reduced while stability and Lysholm scores of the groups had no significant difference. Conclusion: PRP injection had a short-term statistically significant pain reduction effect that may assist in faster rehabilitation progress, shorter return to play and less detraining which is crucial to professional athletes.

Chronic postsurgical pain (CPSP) is a distressful condition following hernia surgery. A 25-year-old, 55 kg male patient presented with severe pain on the right side of the lower abdomen that radiated to the testicle and the inner side of the thigh. Patient was symptomatic since 5 months following inguinal herniorrhaphy surgery. The pain was not relieved with pharmacological and interventional nerve blocks. An ultrasound-guided ilioinguinal-iliohypogastric (II-IH) block with extended duration (42°C, four cycles of 120 s each) pulsed radiofrequency (PRF) and a diagnostic genital branch of genitofemoral nerve (GGFN) block provided pain relief. After 1-month, an extended duration PRF in GGFN resulted in complete resolution of symptoms. During a regular follow-up of 9 months, patient reported an improved quality-of-life. We believe the successful management of CPSP following hernia repair with single extended duration PRF of II-IH and GGFN has not been described in the literature.

Study Objective: To examine the impact of visual stimulation (exciting red and tranquilizing green) on the score of the Numerical Rating Scale (NRS) questionnaire in patients with chronic pain.Design: Prospective randomized study.Setting: Outpatient pain clinic of a university hospital.Patients: Two hundred outpatients with chronic pain.Interventions: Patients were randomly assigned to receive the NRS questionnaire printed on either red paper (red group) or green paper (green group).Measurements: The questionnaire included 5 questions consisting of the NRS in the worst, in the least, and in the average pain during last week and the NRS at rest and on movement at present. Calculation of the sample size was based on power of 0.8 and α=.01.Main Results: The NRS scores were not different between the 2 groups. In patients on antidepressants (n=76) and with depression (n=49), the NRS scores, except the NRS in the worst pain during last week score in patients on antidepressants, were significantly higher in the red group than in the green group (all P≤.040). In the red group, the NRS scores were significantly higher in patients with than without depression (all P≤.003), whereas there was no difference in the scores between patients of the green group with and without depression.Conclusion: Our findings suggest that visual/emotional stimuli and treatment with antidepressants alter the NRS score in patients with chronic pain.

Background: Inflammatory markers are increased during vaso-occlusive crisis (VOC) in adult patients with sickle cell anemia (SCA), but this is not clear in clinical steady state. Aim: The present study aims to establish the frequency and intensity of bone pain episodes in adult patients with SCA in clinical steady state and to determine the correlation between different inflammatory markers, other variables including QT dispersion (QTd) and pain frequency and intensity in SCA. Patients and methods: Patients were classified into two groups: group 1, those with more than three hospital admissions in the last 6 months, and group 2, those with no hospital admission. Pearson correlation between variables such as body mass index (BMI), level of tumor necrosis factor (TNF-α), interleukin-1 (IL-1), C-reactive protein (CRP), hemoglobin (Hb), reticulocyte count, white blood cell count (WBC), ferritin, lactate dehydrogenase (LDH), parathormone (PTH), vitamin D3 (25-OH cholecalciferol) and bone pain frequency with severity was evaluated. Results: Forty-six patients were enrolled in this study with a mean age of 18.47±5.78 years, with 23 patients in each group. Vitamin D3 and Hb were lower (17.04±5.77 vs 37.59±4.83 ng/L, P<0.01 and 7.96±0.3 vs 8.44±0.27 g/dL, P<0.01, respectively); the inflammatory markers showed significantly higher level of TNF-α, IL-1 and CRP (56.52±5.43 pg/ml, 44.17±4.54 pg/ml and 3.20±0.72 mg/L, respectively, P<0.05); WBC, LDH and reticulocyte count were also significantly higher and the QTd was higher (45.0±2.22 vs 41.55±0.8 ms, P<0.05) in group 1 when compared with group 2. Pearson correlation coefficient showed significant positive correlation between serum level of TNF-α and bone pain frequency (r=0.414, P<0.005) and serum level of IL-1 (r=0.39, P<0.008). Conclusion: There is a strong positive correlation between TNF-α, IL-1 and WBC and bone pain frequency in steady state in adult patients with SCA. CRP and low hemoglobin had weak positive correlation. QTd was significantly longer in patients who had hospitalizations with VOC. [ABSTRACT FROM AUTHOR]

Backgrounds/aims: The aim of this study was to investigate the effect of rectal and intrauterine anesthesia during vaginoscopic hysteroscopy.Methods: This was a randomized, double-blind, placebo-controlled study. Patients were randomized to rectal indomethacin, intrauterine lidocaine and placebo groups. Patients with conditions that could cause or contribute to pelvic pain were excluded. Pain was evaluated with Visual Analog Scale, when the cervical canal was passed, while within the cavity and at 10 min after procedure. The Analog Pain Scale scores of the 3 groups were compared with the Kruskal-Wallis 1-way analysis of variance test. A value of p < 0.05 was accepted as statistically significant.Results: The study included a total of 206 patients. No difference was seen between the groups in respect of indication, age, gravid and duration of procedure. While the anesthesia was determined as superior to the placebo in reducing pain at all 3 stages (p < 0.05), intrauterine lidocaine was determined to be more effective than rectal indomethacin in reducing pain within the cavity and 10 min after the procedure (p < 0.05).Conclusion: Rectal or intrauterine anesthesia applied with the vaginoscopic technique is useful in hysteroscopy. However, intrauterine anesthesia is more effective in reducing pain. [ABSTRACT FROM AUTHOR]

Objective: Tonsillectomies are the most frequently applied operations in the ENT practice. Even though different surgical tonsillectomy techniques have been used, bipolar cautery is the most frequently used one. Our aim was to compare postoperative bleeding rates, pain scores and recovery times in tonsillectomies performed by using bipolar cautery in Joules (1Watt·sec or Ws) calculated by multiplying Watts by the duration of cauterization. Methods: Adenotonsillectomy and tonsillectomy patients, admitted to the Department of otorhinolaryngology of Izmir Ataturk Training and Research Hospital and Mardin State Hospital, between January 2007 and December 2012 constituted the study group prospectively. The patients divided into 4 groups due to the energy they exposed. Results: Patients in Group 1 recovered most rapidly (mean recovery time, 13.9±1.8 days). Statistically significant results were obtained between Groups 1 and 4 and also Groups 2 and 4 when recovery times of the patient groups were evaluated with Bonferroni correction test. Conclusion: As a result, for hemostatic control, electrocauterization should be used at lower doses and short-term as possible so as to decrease frequency of bleeding episodes, alleviate postoperative pain and accelerate wound healing.

Introduction: Back pain can be one of the most common health problems, causing suffering, disabilities, and financial losses. Postural models for pain treatment state that poor posture alters the joint position and causes pain, such as back pain. Muscular Chain Therapy (MCT) is a technique that is used to treat posture pathologies, among others., Purpose: The aim of the present study was to assess the efficiency of a single session of Muscular Chain Therapy (MCT) on complaints of undiagnosed musculoskeletal spinal pain., Setting: Physical therapy clinic of the University of Center-West (Guarapuava, Brazil)., Participants: 100 subjects, aged between 20 and 39 years, with complaints of spinal musculoskeletal pain., Research Design: Randomized controlled trial., Intervention: The participants were randomly assigned by a non-care provider into two groups: The MCT Group that received Muscular Chain Treatment and the Control Group that received a placebo treatment of 15 minutes turned off ultrasound therapy. All volunteers were assessed before and after treatment using an analog pain scale. A score of 0 indicated no pain and 10 was the maximum degree of pain on the scale., Main Outcome Measure: Degree of pain measured by analog scale., Results: The chi-square goodness of fit test was used to compare gender distribution among groups displayed a p value = .25. Subject age had differences analyzed using the unpaired t test (p = .44). Pain assessment for treatment and placebo control groups was analyzed using a paired t test and unpaired t test. The paired t test was used for intragroup before/after treatment comparison (MCT p = .00001; Control Group p = .0001). The unpaired t test was used for comparing the difference of the pain level before and after treatment between groups (p = .0001). A priori statistical significance was set a p = .05., Conclusion: It is possible to conclude that one MCT session is an effective treatment of undiagnosed spinal musculoskeletal pain.
