Abstract
Botulinum neurotoxins (BoNTs), derived from Clostridium botulinum, have been employed to treat a range of central and peripheral neurological disease. Some studies indicate that BoNT may be beneficial for pain conditions as well. It has been hypothesized that BoNTs may exert their analgesic effects by preventing the release of pain-related neurotransmitters and neuroinflammatory agents from sensory nerve endings, suppressing glial activation, and inhibiting the transmission of pain-related receptors to the neuronal cell membrane. In addition, there is evidence to suggest that the central analgesic effects of BoNTs are mediated through their retrograde axonal transport. The purpose of this review is to summarize the experimental evidence of the analgesic functions of BoNTs and discuss the cellular and molecular mechanisms by which they can act on pain conditions. Most of the studies reviewed in this article were conducted using BoNT/A. The PubMed database was searched from 1995 to December 2022 to identify relevant literature.

Abstract
Abstract
Background
Exosome administration is a novel medical approach that promises excellent immunomodulatory properties without the conventional side effects of current antitumor necrosis factor drugs and stem cells. This study aimed to assess the safety and efficacy of using mesenchymal stem cell (MSC) exosomes to treat refractory fistulas in patients with inflammatory bowel disease.
Methods
MSCs were derived from the umbilical cords and their exosomes were isolated. Five patients with refractory perianal Crohn’s disease fistulas with a median age of 35 years (range 31–47 years) were enrolled in the study. Exosome injections were administered in the operating room to patients with refractory fistula (fistulas that are irresponsive to anti-tumor necrosis factor-α administration within 6 months). Six months later, a physical examination, face-to-face interviews, and magnetic resonance imaging were employed to evaluate the therapy responses of patients.
Results
The outcomes within 6 months after initiation of therapy showed that four patients had responded to therapy. Three patients who received exosome injections exhibited complete healing, while one reported no improvement and active discharge from the fistula site. In addition, five patients (100%) reported neither systemic nor local adverse effects.
Conclusions
Injection of exosomes extracted from MSCs demonstrates safety and a satisfactory therapeutic effect, as evidenced in this and other studies, and may play a significant role in the future treatment of gastrointestinal fistulas.

Abstract
Background The correct placement of the endotracheal tube is a cornerstone of safe anesthesia. Different methods, such as auscultation, capnography, and ultrasound, have their own limitations regarding the confirmation of endotracheal intubation, reinforcing the idea that a single technique is not foolproof. This study proposes a new technique in this regard. Materials and Methods A total of 600 patients were enrolled in this study, and tracheal intubation was checked with palm pressure and disposable plastic glove inflation and pulsation. Results The data were analyzed using the t-test and Mann-Whitney U test that indicate 94% and 94.8% sensitivity for palm pressure and bag pulsation, respectively, and a 100% positive predictive value for both tests. Conclusion Palm pressure and bag pulsation are accurate, inexpensive, and reliable techniques to confirm proper tracheal intubation.

Abstract
BACKGROUND Postoperative Nausea and Vomiting (PONV) is a multifactorial surgical complication with an unclear underlying cause. Anesthetic methods, patients' characteristics and the type of surgery are considered as factors affecting PONV. This study was designed to compare the effect of inhalational and intravenous anesthesia in abdominal surgery on the incidence and severity of PONV. METHODS A single-blinded prospective randomized clinical trial on 105 patients aged 18-65 years was carried out. Patients were divided in two groups of Total Intravenous Anesthesia (TIVA) and Inhalational anesthesia. The incidence and severity of PONV were examined at 0, 2, 6, 12, and 24hours after the surgery. The use of a rescue antiemetic was also evaluated. RESULTS Fifty point nine percent of the patients in the inhalation group and 17.3% of the patients in the intravenous group developed PONV (p <0.001). The incidence of vomiting was reported in 11.3% of the Inhalational group and 3.8% of the TIVA group (p=0.15), and 24.5% of patients in the Inhalation group and 9.6% of patients in the intravenous group needed an antiemetic medication (p=0.043). CONCLUSION The incidence of postoperative nausea and vomiting and the need for administration of an antiemetic rescue drug, and the severity of nausea in patients were significantly lower in the TIVA group.

Abstract
Background Chronic pain is the third main problem of global health and the most common cause of long-term disabilities. The duration that patients suffer from chronic pain is directly proportional to the extent of the suffering and to the amount of health care resources allocated to this problem. There is no research that has studied the risk factors associated with the long pain duration in chronic pain patients. Methods We investigated the potential risk factors associated with long pain duration in a population with diverse pain conditions in a cross-sectional study. We used a questionnaire that included a number of potential risk factors including sex, age, marital status, household condition, number of children, employment, education, body mass index (BMI), pain intensity, and the level of anxiety/depression. The data were analyzed by univariable and multivariable linear regression models. Results We recruited 780 patients. The analyses showed that age and abnormal BMI had a positive correlation with pain duration. Conclusions The risk factors that might be associated with longer pain duration include older age and abnormal BMI.

Abstract
Background: Xanthogranulomatous pyelonephritis (XGP) is a rare chronic bacterial inflammation of the renal parenchyma and is often a diagnostic dilemma.Case Presentation: We present a challenging case of a patient with XGP. Initially thought to have had renal cell cancer she was treated accordingly with a partial nephrectomy. However, on the final pathology, she was found to have XGP and required further antibiotic therapy and referral to the infectious disease service.Discussion: Management of XGP and diagnostic pitfalls are discussed.Conclusion: XGP is a diagnostic and therapeutic dilemma. Partial Nephrectomy may be appropriate in management of XGP in select cases.

Abstract
BACKGROUND Patients with liver cirrhosis experience a hyperdynamic circulation. OBJECTIVE To investigate the association between early hemodynamic changes and graft function after liver transplant. METHODS Those patients who underwent liver transplantation in 2016 were enrolled in the study. Liver function indices measured in postoperative days (POD) 1, 3, 5, 7, 9, and 11 along with hemodynamic indices including pulse rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), and central venous pressure (CVP) measured q6h in the first 3 days after transplantation were recorded. RESULTS 57 deceased-donor liver recipients with a mean±SD age of 41.4±11.8 years including 33 (58%) males were enrolled in the study. The mean±SD aspartate and alanine aminotransferases, alkaline phosphatase, and lactate dehydrogenase were significantly decreased from 1879±670.5, 369.2±40.5, 174.9±18.8, and 1907.6±323.1 U/L in POD 1 to 37.2±10.7, 243.4±37.3, 207.5±19.5, and 382.4±59.8 U/L in POD 3, respectively (p=0.028, <0.001, 0.002, and 0.001, respectively). During this period, the pulse rate of the patients was significantly (p<0.001) decreased by a median (IQR) of 28.7 (8.5-39.7) beats/min; it was significantly correlated with a decrease in serum hepatic enzymes activities during this period. SBP, DBP, and CVP were significantly increased (p<0.001 for all) during this period. Liver graft function improved significantly earlier in those patients with a mean pulse rate of 87 beats/min compared with others (p=0.03). CONCLUSIONS There may be an association between changes of hemodynamic indices, especially reduction of pulse rate, and improved graft function early after liver transplantation.

Abstract
In epidemiologic studies, patients with head and neck squamous cell carcinoma (HNSCC) are classified mainly by the International Classification of Diseases (ICD) codes. However, some patients are of an unclear subsite, the “gray zone” cases, which could reflect ICD coding error, absence of primary subsite, or extensive primary tumors that cross over multiple subsites of the oral cavity and oropharynx. Patients with gray zone squamous cell carcinomas were compared with patients with oral cavity squamous cell carcinoma (OSCC) or oropharyngeal squamous cell carcinoma (OPSCC) and stratified by human papillomavirus (HPV) status that was determined by p16 immunostaining or HPV serology. Comparisons consisted of clinicodemographic features and prognostic outcomes presented by Kaplan-Meier curves and Cox proportional hazards regression models, reported as hazard ratios. There were 158 consecutive patients with gray zone HNSCC diagnosed at the Princess Margaret Cancer Center between 2006 and 2017: 66 had subsite coding discrepancies against the clinician’s documentation (“discrepant” cases; e.g., the diagnosis by the clinician was OSCC, while the classification by ICD coding was OPSCC), while 92 were squamous cell carcinoma of unknown primary of the head and neck (SCCUPHN) after complete diagnostic workup. Comparators included 721 consecutive OSCC and 938 OPSCC adult cases. All HPV-positive cohorts (OPSCC, discrepant, and SCCUPHN) had similar clinicodemographic characteristics and better 3- and 5-y overall survival and disease-free survival than their HPV-negative counterparts. In contrast, HPV-negative discrepant cases had prognostic outcomes most similar to HPV-negative OPSCC cases, while HPV-negative SCCUPHN had survival outcomes most similar to those of patients with OSCC in this study. HPV-positive status can improve the classification of patients with unclear or discrepant oral/oropharyngeal subsite, an improvement over classification systems that are solely clinician defined or conducted through ICD coding. However, due to clinical practice, we could not make definitive reclassification for patients with HPV-negative gray zone HNSCC.

Abstract
Objective: The goal of this research was to investigate the efficacy of perioperative manual acupuncture in the LV 3 and LI 4 points for lessening hemodynamic changes during endotracheal intubation in patients who were receiving anesthesia. Materials and Methods: This double-blinded randomized controlled study enrolled patients who were undergoing endotracheal intubation, in 2015-2016, during general anesthesia in the general surgery department of the Imam Khomeini Hospital complex, in the Tehran University of Medical Sciences, Iran. The patients were randomly allocated into 2 groups with 30 patients in each group. In the treatment group, acupuncture needles were placed at LV 3 and LI 4, whereas, in the control group, the needles were placed 1 cm lateral to these points. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MAP), and heart rate (HR) before and after placing the acupuncture needles, after induction, immediately, 1 minute, and 3 minutes after intubation were measured and recorded prospectively. Results: The patients had a mean age of 44.45 ± 12.72 years and included 35 (58.3%) males. Before acupuncture, demographic data, mean blood pressure (BP), and mean HR of the patients were not significantly different in the treatment and control groups. The mean SBP, DBP, MAP, and HR of all patients changed over time significantly (P < 0.001 for all). In the treatment group, mean SBP, DBP, and MAP changes immediately after the needles were placed were significantly less than those in the control group (P = 0.033, 0.024, and 0.024, respectively). Conclusions: Although acupuncture could have a very-short-term effect that reduces BP during endotracheal intubation, hemodynamic changes might not be prevented during endotracheal intubation.

Abstract
BACKGROUND AND PURPOSE The best access for hemodialysis is an autologous arteriovenous fistula (AVF). The most helpful way for vasodilation in the upper limb is stellate ganglion block. We aim to evaluate the effect of stellate ganglion block on outcome of vascular access for dialysis. MATERIALS AND METHODS Some 105 hemodialysis patients were randomly allocated to three groups: In group 1, stellate ganglion block was performed before fistula surgery. Group 2 had stellate ganglion block after surgery and group 3 was control group without any block. Primary outcome for all groups was functional dialysis, which is defined as successful hemodialysis for 1 month. RESULTS The three groups were similar in age, gender, and underlying diseases. Stellate ganglion block before operation had a meaningful increase in successful hemodialysis rate, when compared with the other groups (p = 0.02). CONCLUSION Stellate ganglion block before arteriovenous fistula surgery in the upper limbs improves hemodialysis success rate.

Abstract
Lithium tetraborate (Li2B4O7) nanoparticles (NPs) doped with manganese (Mn) were prepared for the first time by the solid-state sintering method. NPs were characterized using X-ray diffraction, scanning electron microscopy, photoluminescence and thermoluminescence (TL) techniques. The synthesized NPs exhibited highest TL response at 0.3 wt% of Mn dopant under gamma irradiation. TL dose response is linear for the absorbed dose from 1 Gy to 20 kGy and beyond this range behaves sub-linear. Such feature makes the synthesized nanophosphor as a promising material for high-dose dosimetry applications. Low fading and good reusability were obtained for the synthesized NPs. Tm-Tstop and computerized glow curve deconvolution procedures were utilized to identify the component TL glow peaks and kinetic parameters of the produced phosphor. Other TL dosimetry features of the prepared NPs are also presented and discussed.

Abstract
ABSTRACT This study was carried out to evaluate the effects of dietary essential oils of ginger (Zingiber officinale), black seed (Nigella sativa) and cone flower (Echinacea angustifolia) on the immune system of cultured rainbow trout, Oncorhynchus mykiss. A total of 360 fish were divided into 4 groups and 3 replicates each containing 30 fish. The fish were fed for 21 days with 1% of the herbal essential oils and with unsupplemented diet as the control group. Haematological and immune parameters including serum lysozyme, number of phagocytic bacteria, Hb, PCV, MCV, MCH, MCHC, number of RBC and WBC were studied. Treatments recorded enhancement in immune parameters compared to the control group. Significantly higher serum lysozyme level and phagocytic germs were detected in the groups fed black seed, ginger and cone flower (P<0.05). However, no significant difference was found in RBC, Hb, PCV, MCV, MCH and MCHC of fish fed the diets containing essential oils and the control group (P>0.05). The results of this study demonstrated that essential oils might strengthen the non-specific immunity of rainbow trout.

Abstract
BACKGROUND Hypospadias is one of the most common forms of congenital malformation of the male external genitalia worldwide. The ratio in the Iranian population is one in 250 live male births. The conversion of testosterone to dihydrotestosterone (DHT) in the presence of steroid 5α-reductase 2, which is encoded by SRD5A2 gene, plays an important role in the normal development of the male reproductive system. METHODS We examined whether SRD5A2 gene mutations (V89L and A49T polymorphisms) are associated with the risk of hypospadias in the Iranian population. We performed exons sequencing for SRD5A2 gene in 109 hypospadias patients. RESULTS We identified two new mutations in the subgroups of affected cases: including a substitution of the nucleotide T > A in the codon 73 [c.219T > A (p.Leu73_Ser74insHisPro)] and an insertion of an extra A nucleotide in the codon 77 [c.229insA* (p.Gly77*)]. Additionally, we performed PCR-RFLP for the two identified polymorphisms and revealed that V89L [OR = 5.8, 95% CI (3.8-8.8), p value < 0.001] and A49T [OR = 10.16, 95% CI (3.94-26.25), p value < 0.001] are significantly associated with hypospadias occurrence in patients. Our haplotype analysis further indicated that the Leu-Ala haplotype increases risk of hypospadias; conversely, the Val-Ala haplotype decreases the risk of hypospadias in the studied patients. CONCLUSIONS This study demonstrates that polymorphisms in the SRD5A2 gene could be considered as a risk factor for hypospadias disease emergence.

Abstract
Critically ill patient transfer is potentially risky and may be lead to morbidity and mortality. Physicians' skill is very important for safe transport. We want to evaluate the effect of clinical course teaching on the promotion of physicians' abilities in the transport of critically ill patients. In an interventional study, 320 interns, male and female, were taught about patient transfer in two groups include in one day clinical course as the small group system (n=160) and other group the lecture base learning (n=160). In the clinical course, each participant under observation of an anesthesiologist in the operation room and ICU was acquainted with mask ventilation, intubation and learned to work with a defibrillator, infusion pump, portable ventilator and pulse oximeter. In lecture group, the anesthesiologist explained the topics by video and dummy. At the end of education course, the interns' abilities were evaluated based on checklist method and scored by the project colleague in all educational items. Three hundred twenty interns, 122 males, and 198 females; were enrolled, two groups. The clinical course training caused improvements in the interns' knowledge and abilities in intubation and use of the defibrillator and portable ventilator vs.lecture group significantly (P<0.005). The males were better than females in laryngoscopy, but the progress of the females was significantly better than males (P=0.003). The rate of adverse events was reduced significantly after clinical course teaching (P=0.041) Clinical course teaching could promote interns' clinical competencies in the transport of critically ill patients.

Abstract
Background: Obesity is a worldwide health problem which is associated with a lot of complications. One of these comorbidities is the metabolic syndrome that is in correlation with abdominal fat thickness and waist circumference. Various methods were used to reduce abdominal fat thickness such as liposuction. A noninvasive method is the topical agent. In this study, we investigated the effectiveness of Arnebia euchroma (AE) ointment on the abdominal fat thickness. Materials and Methods: This study was a double-blind clinical trial which was done at the endocrinology clinic in Khorshid Hospital, Isfahan, Iran, in 2014. After explaining the procedure and obtaining informed consent, the candidates were randomly divided into the case and control groups. The participants of the case and control groups applied AE ointment or placebo for 6 weeks on their abdominal area. Body mass index, waist and buttock circumference, and abdominal fat thickness were measured in both case and control groups at their first visit and then at the next 2, 4, and 6 weeks. We used t-test for comparing parametric variables between groups, paired t-test for changes from baseline to final, and repeated measure ANOVA for changes at different steps. Results: Sixty female candidates participated in this study (thirty in each group). Ten patients left the study and fifty participants finished the trial. At the end of the study, participants had a significant weight loss (2.96 ± 1.6 kg, P < 0.001) that was slightly more in the case group (3.15 ± 1.5 kg vs. 2.75 ± 1.7, P = 0.375). Abdominal circumference also decreased significantly in the participants (11.3 ± 6.7 cm, P < 0.001), but the changes were more significant in the case group (13.9 vs. 6.5 cm, P = 0.004). Similarly, abdominal fat thickness decreased significantly in the participants (2.3 ± 1.1 cm, P < 0.001), although changes were not significantly different between two groups (2.53 vs. 2.04 cm, P = 0.139). Conclusion: Topical AE ointment can reduce the abdominal fat thickness as well as the waist circumference without causing any side effect.

Abstract
The affinity of zeolite nanoparticles (diameter of 8-12 nm) possessing high surface area and high pore volume towards human plasma proteins has been investigated. The protein composition (corona) of zeolite nanoparticles has been shown to be more dependent on the plasma protein concentrations and the type of zeolites than zeolite nanoparticles concentration. The number of proteins present in the corona of zeolite nanoparticles at 100% plasma (in vivo state) is less than with 10% plasma exposure. This could be due to a competition between the proteins to occupy the corona of the zeolite nanoparticles. Moreover, a high selective adsorption for apolipoprotein C-III (APOC-III) and fibrinogen on the zeolite nanoparticles at high plasma concentration (100%) was observed. While the zeolite nanoparticles exposed to low plasma concentration (10%) exhibited a high selective adsorption for immunoglobulin gamma (i.e. IGHG1, IGHG2 and IGHG4) proteins. The zeolite nanoparticles can potentially be used for selectively capture of APOC-III in order to reduce the activation of lipoprotein lipase inhibition during hypertriglyceridemia treatment. The zeolite nanoparticles can be adapted to hemophilic patients (hemophilia A (F-VIII deficient) and hemophilia B (F-IX deficient)) with a risk of bleeding, and thus might be potentially used in combination with the existing therapy.

Abstract
BACKGROUND Liver transplantation is a critical survival point for patients with end stage liver diseases. It can dramatically increase patients' survival if the donor liver is intact. One aspect of liver health is absence of steatosis. Nonalcoholic Steato Hepatitis (NASH) and Nonalcoholic Fatty Liver Disease (NAFLD) are increasing among young adults and patients living with chronic liver diseases. OBJECTIVES In this study, we determined the prevalence of NALFD in livers of brain-dead donors in Imam-Khomeini hospital Complex, Tehran, Iran. We assumed that the calculated prevalence would represent NAFLD prevalence in Iranian population in the age range of 20-60 years. MATERIALS AND METHODS All eligible brain dead liver transplant donors were enrolled in the survey from March 21, 2011 to March 21, 2013 in Imam-Khomeini hospital Complex. Eligible participants were donors aged 20 to 60 years without any obvious history of liver disease. Liver needle biopsy was performed at the end of the transplant operation; time zero biopsy. We calculated the prevalence of NAFLD among brain-dead donors. Moreover, the frequency of NASH was calculated based on the NAS (NAFLD Activity Score). RESULTS Among 116 cases, two were diagnosed as probable NASH. There was a significant association between NAFLD and male gender (P = 0.04). Moreover, we found a higher steatosis level in male gender. There was a significant association between NAFLD and BMI (P = 0.05). Those with BMI more than 27 had severe steatosis. CONCLUSIONS Our comprehensive literature review showed that our study was the first investigation in Iran and the region, which determined the prevalence of NAFLD based on tissue diagnosis. We believe that the prevalence of NAFLD/NASH in our donors can represent the overall prevalence in this age group in Iran.

Abstract
BACKGROUND Methanol poisoning is one of the most important poisoning due to drinking of illegal and non-standard alcoholic beverage in some countries. Relatively limited studies have been carried out to identify the prognostic factors in methanol poisoning. MATERIALS AND METHODS We performed a retrospective study on acute methanol-intoxicated patients, which were admitted on the Loghman Hakim Hospital Poison Center (Tehran, Iran) over a 24-month period. The demographic data, clinical manifestations and paraclinical findings, therapeutic interventions and outcome (survivors with or without complications and non-survivors) were extracted. RESULTS We evaluated 30 patients with methanol poisoning during 2 years. All of the patients were male; with the median age of 25.5 years. Visual disturbances, respiratory manifestations, and loss of consciousness were the most common clinical manifestations on admission time. The results of paraclinical manifestations on admission time were as following: The median of blood methanol level was 20 mg/dL. The median of pH, PaCO2 and HCO3 was 7.15, 22.35 mmHg and 7.2 mEq/L, respectively. Hyperglycemia was observed in 70% of the patients and the median of blood glucose was 184.5 mg/dL. In fourteen of the patients hemodialysis was performed. Median duration of hospitalization was 48 h. Nine of the patients died. There was a significant difference between survivors and non-survivors with regard to coma, blood methanol level, and PaCO2 and blood glucose. Furthermore, we did not observe a significant difference between these two groups regarding to pH, HCO3 level, and time interval between alcohol ingestion to hospital admission and beginning of hemodialysis. CONCLUSION Regarding the results of this study, it can be suggested that coma, PaCO2 and hyperglycemia on admission time could be used as strong predictors of poor outcome.

Abstract
Background Hip fracture–related pain both before and after surgery is generally reported as severe by most patients. Various regional pain control modalities have been described in order to reduce pain in these patients. Objectives Because of the challenges of lumbar plexus block (LPB) and the fact that the effect of combined femoral nerve block/spinal anesthesia in controlling pain after orthopedic surgeries has not been investigated, in this study, we compared the feasibility and efficacy of the 2 techniques in the perioperative management of proximal hip fractures. Patients and Methods The study included 32 patients with femoral intertrochanteric fracture who were randomly divided into the following 2 groups of 16 patients each: combined femoral nerve block/spinal anesthesia group (group I) and LPB group (group II). Patients in group I received 0.17% bupivacaine with 0.7% lidocaine, 20–25 mL for femoral nerve block and bupivacaine 0.5% plus 0.5 mL pethidine (25 mg) for spinal block and patients in group II received 0.17% bupivacaine with 0.7% lidocaine, 30–35 mL. Results The time for performing the block (12.2 ± 3.3 vs. 4.93 ± 1.6 min, P = 0.001) and achieving the block (7.7 ± 0.9 vs. 2.4 ± 1.0 min, P = 0.001) were significantly longer in the combined femoral nerve block/spinal anesthesia group than in the LPB group. Duration of analgesia in the combined femoral nerve block/spinal anesthesia group was longer than that in the LPB group, but the difference was not significant (17 ± 7.3 vs. 16.5 ± 8.5 h, P = 0.873). There were no significant differences in hemodynamic parameters regarding the method of anesthesia in the 2 groups. Conclusions This study confirms that the combination of femoral nerve block with spinal anesthesia is safe and comparable with LPB and can provide more effective anesthesia and longer lasting analgesia for intertrochanteric surgery.

Abstract
AIM Previous studies have indicated that exercise-induced muscle damage might be attenuated by coingestion of protein and carbohydrate supplement. The purpose of this study was to compare the effect of three various ratios of carbohydrate-protein (CHO+PRO) supplements on resistance exercise-induced muscle damage indices. METHODS Twenty-eight untrained male students voluntarily participated in this study and were randomly assigned to one of the four groups: 1) CHO+PRO 2:1 ratio, N.=7; 2) CHO+PRO 3:1 ratio, N.=8; 3) CHO+PRO 4:1 ratio, N.=7; 4) placebo group, N.=6. They performed a single bout of resistance exercise (whole body: 3 set×8-10 reps with 70-75% 1RM), with eccentric concentration. Every group consumed prepared CHO/PRO beverages (9% concentration, 10 mL/kg/bw-1 at different ratios) or the same amount of placebo beverage before and in 15 min intervals during exercise. Blood samples were taken before the exercise bout and also at 1 and 24 h post-exercise. In addition, muscle soreness scores were recorded before and 1, 24, and 48 h postexercise. Repeated measures ANOVA (between-within design) and Bonferroni post hoc test were used to analyze dependent measures (α=0.05). RESULTS Serum creatine kinase (CK) and myoglobin (Mb) increased in all groups compared with pre-exercise but the significant difference among groups was observed in 24 h postexercise, in a way that both CK and Mb levels were higher in placebo group. Muscle soreness increased for all groups from pre to postexercise, but there was not any significant difference among groups at any time point. CONCLUSION Findings of this study showed that CHO+PRO decreased serum CK and Mb at 24 h post exercise, but did not affect muscle soreness at any time points after exercise. Moreover, there were no significant differences between various ratios of CHO-PRO supplementation.

Abstract
Primary tooth impaction is a rare finding during the development of primary dentition. Several factors contribute to the impaction of a deciduous tooth. This report describes the diagnosis and treatment of a 10-year-old boy who presented an impacted second primary mandibular molar. This tooth, located inferior to the second premolar together with an odontoma, was positioned superior to the premolar teeth. Treatment consisted of surgical removal of the impacted deciduous tooth and odontoma and placement of a passive lower lingual holding arch. Periodic examination was indicated for follow-up. Early intervention was recommended to manage orofacial disfigurement and to avoid consequent problems.

Abstract
BACKGROUND Gabapentin has been introduced as an effective agent for post-operative pain control. This study aimed to test the effects of pre- and post-incision administration of different doses of gabapentin on post-operative morphine requirement and pain following lumbar laminectomy. METHODS In this randomized clinical trial, 175 patients were allocated into seven groups of 25 patients each to receive placebo or gabapentin 600, 900 or 1200 mg pre- or post-incision. Total patient-controlled intravenous morphine consumption during the first 24 post-operative hours, and the time to the first demand for morphine were recorded. Pain score at rest (visual analogue scale) was recorded every 30 min in the first 4 h and then every 2 h until 24 h post-operatively. Side-effects were observed. RESULTS In the first 12 h, morphine consumption was less, pain scores were lower and the time to the first demand for analgesia was longer in groups receiving gabapentin 900 or 1200 mg either pre- or post-incision, compared with placebo and gabapentin 600 mg (P<0.001). There was no difference between gabapentin 900 and 1200 mg. Pain score, morphine consumption and time to the first demand for analgesia in equal pre- or post-incision doses of gabapentin were not significantly different. No differences in the side-effects were observed between groups. CONCLUSION Gabapentin 900 or 1200 mg, administered either pre- or post-incision, was found to be effective in pain management following lumbar laminectomy. Similar doses of gabapentin provide the same post-operative analgesia whether administered pre- or post-incision.

Abstract
UNLABELLED Laparoscopy is an effective method of implantation for peritoneal dialysis (PD) catheters. Use of the laparoscopic technique is increasing because of its potential advantages over other techniques. In most patients, selection for PD is based on negative criteria, and because of the need for general anesthesia, the laparoscopic technique can be life-threatening in these patients. On the other hand, local anesthesia is insufficient for laparoscopic catheter implantation. To avoid the need for general anesthesia and to achieve patient safety and satisfaction, we designed a type of conscious sedation (dissociative conscious sedation) and compared the efficacy of subcutaneous (SC) and intravenous (IV) ketamine added to narcotics in patients scheduled for laparoscopic implantation of a PD catheter. METHODS Our prospective randomized double-blind study enrolled 60 adult patients with chronic renal failure who were scheduled for laparoscopic implantation of a PD catheter. Patients were randomly assigned to one of two groups: one receiving IV ketamine, and the other receiving SC ketamine. In both groups, patients were premedicated with IV midazolam 0.015 mg/kg, fentanyl 1-2 μg/kg, and lidocaine 1.5 mg/kg. Patients then received 0.6 mg/kg ketamine either intravenously (IV group) or by subcutaneous injection at the anterior aspect of the forearm (SC group). If systolic blood pressure (BP) increased more than 20% from baseline or exceeded 170 mmHg, IV nitroglycerine (TNG) 50 μg was administered incrementally (repeated 50-μg doses). After a desirable level of conscious sedation was achieved, local anesthesia and nitrous oxide pneumoperitoneum were applied, and the PD catheter was implanted under laparoscopic guidance. Heart rate and BP were measured throughout the procedure. Adverse effects and recovery events were recorded. RESULTS All patients tolerated the procedure well. Administration of TNG was significantly more frequent in the IV ketamine group. Pain intensity during the surgery was similar in both groups. Both groups were comparable with regard to heart rate, but patients in the SC ketamine group had a significantly lower systolic BP at the 2nd measurement and a lower rate-pressure product at the 2nd, 4th, and 5th measurements. All patients in the SC ketamine group were cooperative during surgery and experienced uneventful recoveries; mild hallucinations were observed in 5 patients in the IV ketamine group. In the IV ketamine group, 3 patients lost the ability to cooperate during surgery. All catheters were successfully placed. CONCLUSIONS Dissociative conscious sedation is an acceptable alternative to general anesthesia in laparoscopic implantation of the PD catheter. Ketamine by the SC route is as effective as, but safer than, IV ketamine.

Abstract
BACKGROUND Succinylcholine-induced myalgia is a minor but frequent complication. Its incidence and severity is different according to the studied population. The aim of this study was evaluation of the diclofenac patch effect on postoperative succinylcholine-related myalgia in cesarean section. METHODS The study was a prospective randomized double blind, placebo-controlled trial. One hundred twenty six participants undergoing elective cesarean section (previous cesarean section) were randomized in two equal groups (63 participants in each): the diclofenac patch (containing 180 mg of diclofenac epolamine salt) and the placebo. Surgery was performed following rapid sequence induction of general anesthesia. All patients were paralyzed for intubation by succinylcholine (1.5 mg/kg). Data on baseline characteristics, fasciculation, postoperative myalgia (at 12, 24 and 48 hours after operation), the need to analgesic agents, and adverse effects of diclofenac patch were collected. RESULTS The basic characteristics were comparable between the two groups. The severity of fasciculation did not significantly vary between two groups. In diclofenac group, the incidences of myalgia at 12, 24 and 48 hours after operation were 23.8%, 19.1%, and 12.7% respectively versus incidences of 52.4%, 47.6%, and 44.4% respectively in placebo group. The incidence and severity of myalgia were significantly lower in patients receiving diclofenac through three evaluation periods (all p values less than 0.01). No participants left the study because of the complications. CONCLUSION Diclofenac patch is effective and safe in the prevention of postoperative succinylcholine induced myalgia after cesarean section.

Abstract
AIM To report on a conservative approach for removal of a fractured file in the severely curved apical portion of the distobuccal canal of a mandibular molar. SUMMARY With the assistance of stainless steel hand files and a chloroform-dipped gutta-percha cone, a fractured rotary NiTi instrument was successfully removed. The use of this technique may assist in removal of loose instrument fragments that are not easily accessible to other removal techniques. KEY LEARNING POINTS Instrument fractures do not always lead to an unfavourable prognosis and their removal from the apical third of curved canals should not be routinely attempted. The case highlights that it is possible to conservatively remove loosely bound objects from the hard-to-reach areas of the root canal system.
