Volume 61, Issue 4 (7-2003)
Abstract
One of the disturbing complications of propofol is pain on injection and the incidence ranges from 28% to 90%. Metoclopromide is commonly used as an anti emetic drug. Some investigators reported that this drug could reduce the pain on injection of propofol. The aim of this study was to assess and comparison of the efficacy of propofol pretreatment with metoclopromide in incidence and severity of its pain on injection.
Materials and Methods: In a randomized, prospective, double-blinded, placebo-controlled trail, 150 patients 18 to 40 yr old were randomly allocated in one three groups. C group (2ml of normal saline), L group (40mg lidocaine in 2ml), M group (l0mg metoclopromide in 2ml). Immediately after injection of study or placebo drugs, 10 mg of propofol with injection rate of 0.5 ml/s (In 4 Seconds) were injected in to the same vein that was inserted to the most prominent dorsal hand vein. Pain severity was measured using Visual Analogue Pain Scale that were educated to the patients before the trail (0 for no pain and 100 for the most aggressive pain in life) and values other than zero was encountered pain appearance. Patients with signs of sedation were excluded.
Results: There was no statistically significant difference between patients in three groups in number of men and women (P = 0.66), age (P = 0.29) and weight (P = 0.49). Furthermore severity (P = differences (C = 41.18, L - 25.4 and M = 13.1, P < 0.001) and patients in metoclopromide group experiences lower pain than other two groups (P < 0.001). Pain incidence in Control group was 77.1% and it was significantly reduced in lidocaine and metoclopromide group (P = 0.002), but there were no significant difference between them (P = 0.051). The 0.69) and incidence (P ~ 0.29) of pain has no significant difference between men and women. Pain severity between three groups has significant results showed that metoclopromide could significantly reduce the seventy of pain on injection of propofol more than lidocaine (opposite to diazepam), but they had no difference in pain incidence. It might lie on the different mechanisms that they produce pain. Pain on injection of diazepam is primarily attributed to propylene glycol, as a vehicle, but the pain mechanism in propofol is remaining unknown.
Conclusion: Finally as regards to other useful effects of metoclopromide including postoperative nausea and vomiting and propofol induction dose reduction, especially when there is a medical condition where lidocaine is contraindicated, it may be a reasonable alternative before injection of propofol.

Abstract

Background: One of the disturbing complications of propofol is pain on venous injection. Some investigators had reported that corticosteroids effectively induce and prolong the duration of local anesthetics. The aim of this study was to assess and comparing the efficacy of propofol pretreatment with dexamethasone in prevalence and severity of its pain on injection.

Materials and Methods: In a randomized, double-blinded, placebo-controlled prospective study, 90ASA I and II, 20 to 60 years-old patients scheduled for elective surgery under general anesthesia were enrolled. In all patients, one of the veins of both hands was catheterized with a 20 G catheter. Then randomly, and simultaneously 2 ml dexamethasone (8 mg) was injected to one of them and 2 ml of normal saline was injected to other. After 30 seconds, 2 ml propofol (20 mg) was injected to both hands, at the same time in 30 seconds. Pain intensity was measured using VAS system.

Results: The age mean was 32.87±5.61. Twenty nine patients were male (32.2%). The mean of pain during propofol injection was significantly lower in dexamethasone group than normal saline group (1.61 vs.4.21 respectively, p< 0.05). Also the pain incidence was significantly lower in dexamethasone group compared to normal saline group (20% vs. 57.78% respectively, p> 0.05).

Conclusion: Intravenous administration of 8 mg dexamethasone before propofol IV injection significantly decreases the pain on injection of propofol.

Shoaybi G, Soltanimohammadi S, Rajabi M,
Volume 65, Issue 2 (3-2008)
Abstract
Background: Propofol, an anesthetic noted to give rapid recovery, causes discomfort at the site of injection. A number of methods to reduce propofol-induced pain have been tried, including pretreatment with lidocaine, with varying results. Here, we evaluate the efficacy of magnesium sulfate compared to that of lidocaine and normal saline in mitigating propofol-induced pain.
Methods: One hundred ASA I and II adults, aged 20-50 years, scheduled for elective surgery requiring two IV lines with 20-gauge cannulae in the dorsum of each hand, were enrolled in this study. The patients were randomly placed into two groups of 50 patients. In each patient, one hand was the case study and other hand was the control. Group A received 10% magnesium sulfate in one hand and normal saline in the other hand. Group B received 10% magnesium sulfate in one hand and 1% lidocaine in the other hand. All injections had a volume of 2 ml. After 30 seconds, 2 cc of 1% propofol was injected simultaneously into each hand. Pain was assessed according to the VAS rating system, ranging from 0 (no pain) to 10 (the most severe pain), with a minimum interval of 3 as significant pain. Data were analyzed by chi-square and independent t tests. A P value <0.05 was considered significant.
Results: In Group A, the mean pain in the hand premedicated with magnesium was 1.46±1.07, compared to 4.54±2.15 for that of the other hand that had received normal saline (P=0.001). In group B, the mean pain in the hand that had received magnesium was 0.82±1.34, compared to 0.78±1.07 for that of the other hand, which had received lidocaine (P=0.86).
Conclusion: Intravenous magnesium and lidocaine pretreatments are equally effective in attenuating propofol-induced pain, and were better than normal saline in attenuating propofol-induced pain.

Volume 67, Issue 8 (11-2009)
Abstract

Background: Dopaminergic is the most important neurotransmitter is fear. The dopaminergic mesolimbic pathway has essential role in excitable behavior, and it's role in Parkinson disease. The aim of this research in study, the effect of dopaminergic pathway in fear response.
Methods: The elevated plus maze was used in combination with the percentage of time spent in the open arms of the maze (OAT%) and the percentage of entries into the open arms (OAE%) to measure fear. Increases in the OAT% and OAE% indicate an anxiolytic effect (reduction in anxiety), whereas decreases in the OAE% and OAT% indicate an anxiogenic effect. After five days, the rats were injected with saline and different doses of sulpiride and Bromocriptine.
Results: Results showed that intracerebroventricular administration of sulpiride, in the doses of 5, 20μg/rat and bromocriptine, D2 agonist in doses 65, 95μg/rat produced a significant effect comparing to sham groups (p<0.05). While intracerebroventricular administration of sulpiride 15, 10μg/rat, and bromocriptine 70, 80μg/rat, did not show any significant effect comparing with sham group (p<0.05). In the current research intracerebroventricular administration of sulpiride, D2 antagonist at the doses of 5, 10, 15, 20μg/rat and Bromocriptine, D2 agonist in the doses of 65, 70, 80, 95μg/rat were used and theire effect on the fear behavior were studied.
Conclusions: The possible effect of Dopaminergic system in the fear process, especially D2 receptor increase fear.

Abstract
Background: Cutaneous leishmaniasis is a major health problem in Iran and especially Isfahan province is considered as an endemic area for this disease. Regarding the previous report of positive effects of Cassia fistula boiled extract in the treatment of cutaneous leishmaniasis, this study was designed to evaluate the effect of combination therapy with intralesional meglumine antimoniate and Cassia fistula fruit gel compared to placebo in this disease.
Methods: 140 patients with cutaneous leishmaniasis referring to Skin Disease and Leishmaniasis Research Center of Isfahan (SDLRC) were randomly allocated in two groups. One group received intralesional meglumine antimoniate injection and Cassia fistula fruit gel and the second group were treated with intralesional meglumine antimoniate and placebo gel. Improvement was defined as complete cure, partial cure and treatment failure.
Results: At 12 week, 47 patients treated with intralesional meglumine antimoniate and topical Cassia fistula fruit gel achieved complete cure (67.1%) compared to 29(41.4%) patients in placebo treated group. There was significant difference in cure rate between two treatment groups of this study (p<0.001). Nine patients (19%) in each group suffered from adverse effects of the treatment such as itching and erythema. There was no significant difference in this regard between two groups (p=0.82).
Conclusions: The results of this study shows the efficacy of Cassia fistula fruit gel in increasing the cure rate of cutaneous leishmaniasis lesions achieved by intralesional meglumine antimoniate. Combination therapy of intralesional meglumine antimoniate and Cassia fistula fruit gel could be suggested as a choice for the treatment of acute cutaneous leishmaniasis lesions.

Volume 71, Issue 4 (7-2013)
Abstract

Background : One of the important problems in fertilization in vitro (IVF) is failure of implantation. This could be the result of estrogen and progesterone effects in endometrial acceptance during ovulation stimulation. Although progesterone has a vital role in primary phase of pregnancy, but the estradiol role in luteal phase is unknown. The aim of this study is assessment of the ratio of estradiol to progesterone in embryo transfer day on Intracytoplasmic sperm injection (ICSI) outcomes.

Methods : This is a cohort study. The subjects were 311 infertile women referred to Urmia Kosar infertility clinic & Urmia reproductive health research center who treated with ICSI method between August-Jan 2011 . Five cc blood was drawn for determine of estradiol and progesterone in transfer day. Transfer occurred after a variable in vitro culture period ranging from 48 to 72 hours after ovulation induction. Chemiluminescent ELICA the level of mention hormones was used to determine the ratio of the progesterone level to the estradiol serum level and was compared based on treatment outcomes.

Results : A total of 311 patients, 115 (37%) were pregnant and happened abortion were 18 (5.8%) . The mean ratio of estradiol to progesterone in transfer day in two groups of miscarriage/ non miscarriage and pregnant/ non pregnant was 32.26±23.86 , 28.17±26.5 and 28.58±2.4 , 36.09±4.39 respectively. There is no significant difference between two groups in regard of estradiol on progesterone ratio (P=0.5, P= 0.2) .

Conclusion: The results of this prospective cohort study show that there is no effect of estradiol to progesterone ratio on day of embryo transfer, successful pregnancy in ICSI cycles and abortion rate following of ICSI .

Abstract
Background: The aim of this study was to assess the role of consolidative intraperito-neal chemotherapy with carboplatin in decreasing relapse and increasing survival in advanced epithelial ovarian cancers, as well as evaluation of its toxicity. Methods: In this clinical trial 30 patients with epithelial ovarian cancer in stages II-IV who had complete surgery (optimal debulking surgery) received six standard cycles of intravenous carboplatin and paclitaxel. They were enrolled through non-random se-quential selection. The control patients were similar to case group in stage (II-IV) and pathology (epithelial ovarian cancer). The control group was evaluated retrospectively through hospital files. This clinical trial performed in Gynecology Oncology department in Tehran Valiasr University Hospital, during 2005-2010. They including 18 cases as the intervention group receiving intraperitoneal chemotherapy and 12 patients as the control group with only retrospective follow-up. The cases received 3 cycles of 400 mg/m2 intraperitoneal carboplatin every 21 days following intravenous chemotherapy. Relapse of disease was diagnosed as increasing or even doubling CA125 serum titer during one month, or any CA125 above 100 IU, or an abdominal or pelvic mass in ul-trasound or physical exam. Mean survival of two and five years, progression-free inter-val (PFI), overall survival (OS), relapse, demographic parameters, drug toxicities, path-ologic types of cancers in two groups were coded and compared using SPSS 14. Any P<0.05 was considered as a significant difference. Results: The mean ages of cases and controls were 52.4±8.6 and 55.1±11.5 years. The mean duration of relapse-free survival was 13±8.6 months for the cases and 9.5±4.3 months for the control patients (not statistically different, P>0.05). The mean overall survival for cases and controls were 39±16.5 and 30.8±16.2 months, respectively (no significant difference, P>0.05). The frequency of drug toxicities in the cases was 5.6%, and consisted of mild-to-moderate abdominal pain, nausea and vomiting. Conclusion: It seems that consolidation therapy with intraperitoneal carboplatin may not increase overall survival, reduce relapse rate or decrease mortality, though it does not induce considerable side effects. Since the mean survival in the intervention group was nine months more than controls, this difference may be clinically significant.

Abstract
Background: With introduction of intracytoplasmic sperm injection with testicular sperm extraction or precutaneouse epididymal sperm aspiration, effective treatment was provided for azoospermic men. The aim of present study was to compare clinical outcome following intracytoplasmic sperm injection using extracted testicular/epididymal sperm or ejaculated severe oligoasthenoteratozoospermic sperm. Methods: After retrospective evaluation of more than four hundred medical records of patients undergoing intracytoplasmic sperm injection Mehr medical institute (between 2011-2012), 45 cycles with severe eligoasthenoteratozoospermia and 34 cycles with azoospermia were included. Patients were treated with gonadotropin releasing hormone agonist. The clinical characteristics and intracytoplasmic sperm injection outcome such as the rate of fertilization, implantation and clinical pregnancy were compared between the two groups. Results were presented as mean±standard deviation and number (percent). Differences between variables were analyzed using student's t test and the chi-square test was used to examine differences between categorical variables. P value less than 0.05 were considered as statistically significant. Results: Mean of female age (29±4.9 vs. 30.2±5.8), body mass index (26.9±5.3 vs. 26.9±3.8), estradiol level on human chorionic gonadotropin administration day (1375.6±843.9 vs. 1181.8±673.1), total number of retrieved oocytes (9.7±5.3 vs. 9.2±5.9) and metaphase II oocytes (7.7±5.1 vs. 7.5±5.4) were similar between the two groups. Of 436 and 313 retrieved oocytes, respectively 232 and 163 oocytes were ferti-lized in oligoasthenoteratozoospermic and azoospermic groups (53.2% vs. 52.1%, P=0.214). There were not statistical differences between groups in number of trans-ferred top quality embryos (1.5±1.2 vs. 1±1.2, P=0.09), implantation rate (22.7% vs. 16.9%, P=0.238) and clinical pregnancy rate (21 (47.7%) vs. 11 (35.4%), P=0.199). Conclusion: Intracytoplasmic sperm injection with precutaneouse epididymal sperm aspiration and testicular sperm extraction are effective methods to treat azoospermic men and its clinical outcome were comparable to ejaculated sever oligoasthenoterato-zoospermic cycles. It can be concluded that the influence of sperm quality and origin on intracytoplasmic sperm injection outcome are the same.

Abstract
Background: Last decades, we have observed major improvements in treating infertility by using microinjection. However, reduction in abortion or increase in fertility has not been significant. It seems use of corticosteroids improves clinical outcomes during assisted reproductive technology (ART) techniques. Therefore, this study tried to show how corticosteroids therapy improves the results of intracytoplasmic sperm injection (ICSI). Methods: This semi clinical trial study without control group was included infertile women with more than one year’s infertility and were candidate to ICSI which were referred to Kosar Infertility Center, Urmia University of Medical Sciences from April 2011 to September 2013. Patients received prednisolone which was started 20 mg/day from one day before embryo transfer to 7 days, then for 2 days more 1 tablet and stopped. Pregnancy outcomes were chemical and clinical pregnancy, ectopic pregnancy, multiple pregnancy and rate of abortion before 20 weeks. Beta human chorionic gonadotropin (HCG) test was performed. Patients with positive pregnancy test were followed by sonography in 6, 12 weeks and 20 weeks of pregnancy. Results: One hundred and eighty one patients entered to the study. The mean± SD of age and fertility duration were 30.42± 6.07 and 7.69± 5.54 years. The mean± SD of transferred embryo was 4.60± 1.10 and embryo grading was 138 (44.7%) grade A, 124 (40.1%) grade B, 47 (15.2%) grade C, respectively. There were no significant difference between fresh/frozen embryo transfer in pregnancy outcomes (P> 0.05 in all of outcomes comparison). The incidence rate of biochemical pregnancy was 48.1% (87), clinical pregnancy rate with appearance of fetal heart was 44.2% (80), incidence rate of abortion before appearance of fetal heart (6 weeks) in women with intra-uterine pregnancy was 5.9% (5), incidence rate of abortion before 20 weeks was 12.9% (11). Incidence rate of ectopic pregnancy was 2.3% (2) and rate of multiple pregnancies was 32.5% (26). Conclusion: Our study suggests that the infertile patients who receive prednisolone in ICSI cycle, had improved pregnancy outcomes. Additional confirmatory studies are needed.

Abstract

Background: Receptivity of endometrium has a critical role in the establishment of pregnancy after embryo transfer in the treatment process of infertile couples. As the glycoprotein CA-125 is a product of human endometrium and is measurable in the peripheral circulation, it is investigated whether it might serve as an indicator of endometrial receptivity and predictor of pregnancy following Intracytoplasmic sperm injection (ICSI).

Methods: In an observational diagnostic study, over a twelve-month period (from August 2013 to July 2014), all couples with male-factor infertility who attended to infertility clinic of Moheb Yas Hospital, Tehran and were candidate of performing ICSI, were invited to participate in the study. Based on the inclusion criteria of study, 64 women were eligible to take part in the study. They were assessed for serum CA-125 levels on the day of human chorionic gonadotropin (HCG) administration and also on the day of oocyte retrieval. After ICSI, the possibility of pregnancy was assessed by measuring serum concentration of &beta-HCG on 14 days after embryo transfer and also by visualizing the gestational sac by trans-vaginal ultrasound examination on four to five weeks after transfer. The pregnancy rate was compared between those with normal and high CA-125 levels.

Results: Among the subjects, 15 patients (23.4%) had high CA-125 levels, and totally 19 patients (29.7%) experienced pregnancy. Among those with normal and high CA-125 levels, 16 patients (32.7%) and 3 subjects (20%) experienced pregnancy, respectively, that showed no statistically significant difference according to Chi-square test (P=0.348). Also, according to the Fisher’s exact test, there was no correlation between CA-125 levels and the rate of pregnancy on the basis of body mass index (BMI).

Conclusion: Totally, according to the obtained results in current study, it may be concluded that serum CA-125 levels has no prognostic value in prediction of the outcomes of ICSI among infertile couples with male-factor infertility.

Volume 76, Issue 9 (12-2018)
Abstract
Background: Adding morphine as adjuvant intrathecal drug for cesarean section is a gold standard for post-operative analgesia according to literature, but because of frequent incidence of nausea, vomiting and pruritus, it has limited popularity. Various mechanisms have been demonstrated for the opioid-induced pruritus, with a variety of medications with different mechanisms of actions for prevention and treatment. The aim of this study was to determine the effect of intramuscular promethazine on intrathecal morphine-induced pruritus after cesarean delivery.
Methods: In a retrospective descriptive-analytical study, recorded data of two thousand American Society of Anesthesiologists (ASA) I or II women undergoing elective cesarean delivery at the Bahman Hospital of Tehran, Iran, during the period of 2008 to 2013 were reviewed. Participants were divided into two groups of one thousand for each theme; the initial group underwent spinal anesthesia by employing intrathecal morphine as part of a standard anaesthetic regimen without prophylactic administration of promethazine, the subsequent group received 25 mg intramuscular promethazine after intrathecal drug administration. The incidence and severity of pruritus (absent, mild, moderate or severe) and intensity of pain using numeric rating scale (NRS) and also the incidence of nausea and vomiting were examined as main variables. All data were analyzed using SPSS software, version 22 (IBM SPSS, Armonk, NY, USA) and P values of less than 0.05 were considered as statistically significant.
Results: The incidence of nausea (P=0.025) and vomiting (P=0.046) was different in two groups; with statistical significance. The mean score of pain according to numeric rating scale (NRS) was similar in both groups (P=0.46). The frequency of pruritus was statistically similar in both groups, (P=0.302); but the severity of itching showed statistically significant difference between two groups (P<0.001).
Conclusion: The severity of pruritus was significantly reduced by intramuscular administration of 25 mg promethazine, shortly after spinal morphine administration but it was shown to be ineffective to reduce the incidence of pruritus. Also, the incidence of post-operative nausea and vomiting (PONV) was less by intramuscular promethazine application.

Abstract
Background: Retinal vein occlusions are one of the most common form of retinal vascular disorders and could lead to vision loss due to macular edema, macular ischemia and sequelae from neovascularization. Anti-venous endothelial growth factor (anti-VEGF) treatment is the choice strategy of treatment for patients with macular edema secondary to central retinal vein occlusion (CRVO). There is an evidence of body with the controversies regarding increment of choroidal thickness in CRVO condition. The current study was designed to determine whether baseline subfoveal choroidal thickness may be an indicator for visual and anatomical outcome of bevacizumab in patients with CRVO macular edema.
Methods: This study was a prospective clinical cohort study that enrolled in 23 new cases of treatment-naïve central retinal vein occlusion (CRVO) from February to July 2017 who were visited in Feiz Eye Hospital, Isfahan, Iran. Patients received a single injection of bevacizumab and were followed for 30 days. Ratio of subfoveal choroidal thickness (SFCT) was measured using enhanced depth imaging spectral-domain optical coherence tomography (EDI-OCT). Ratio of SFCT of the CRVO eye to the fellow healthy eye (SFCT1/F) was taken as independent variable. Changes of best-corrected visual acuity (BCVA) in LogMAR (ΔBCVA, functional response) and secondary to baseline central macular thickness ratio (CMT2/1, anatomical response) in the CRVO eyes were taken for comparative and correlative analytics.
Results: A total of 46 eyes from 23 patients with the mean age of 64.60±10.19 years were included in this study. Baseline SFCT was higher in CRVO eyes (251.91±46.09 µm) in comparison to the fellow eye (206.95±26.62, P<0.0001). Also central macular thickness in CRVO eyes were significantly higher in CRVO eyes in comparison with fellow eye (531.04±38.22 vs 303.30±33.59, respectively, P<0.05). SFCT1/F, correlated moderately with anatomical (CMT2/1) and strongly with functional response (ΔBCVA).
Conclusion: Bilateral evaluation of SFCT by EDI-OCT in all newly diagnosed CRVO cases is recommended to determine if there is a relative increase in choroidal thickness. This may help predict short-term response to anti-VEGF therapy.

Volume 79, Issue 3 (6-2021)
Abstract
Background: The number of patients suffering from diabetic ulcers has been increased in recent years and the current therapies have faced failure. This study aimed to investigate the effects of Wharton’s jelly stem cells (WJMSCs) on the diabetic wound in an animal mode.
Methods: During this laboratory experimental study carried out in Skin and Stem Cells Research Center from March 2021 to November 2021, WJMSCs were isolated and their differentiation capability to osteocytes and adipose cells was assessed using the colorimetric method, and the expression of specific markers was evaluated using flow cytometry. 12 male Wistar rats weighing 200 to 250 grams were purchased from the Pasteur Institute and kept in the animal room in standard condition. Streptozotocin was used to induce diabetes in male Wistar rats. Animals were divided to control (normal saline injection: n=6) and WJMSCs injection (n=6) groups. Wounds with 0.8 cm in diameter were made on the back of rats. After subdermal injection of normal saline and WJMSCs, wound healing was evaluated 7, 14 and 21 days using the photography method. Data were analyzed using a t-test and analysis of variance.
Results: The results showed that the isolation process should be performed no later than a few hours after the cesarean section. Storing the sample for one day or more caused sample contamination leading to significant failure in cell proliferation and differentiation. WJMSCs were positive for specific mesenchymal stem cell markers (CD44, D73, CD90 and CD 105, and negative for CD45 and CD 34. They were capabale to differentiate into osteocytes and adipose cells and had a high viability rate (83.1%). Subdermal injection of WJMSCs in diabetic rats resulted in acceleration of diabetic wound healing compared with the control group.
Conclusion: Subdermal injection of WJMSCs can effectively accelerate diabetic wound healing. According to which, applying Wharton’s jelly stem cells can be considered in cell therapy particularly in the field of diabetic wound healing.

Volume 79, Issue 7 (10-2021)
Abstract
Background: Nicolau syndrome is a rare condition that happens after intramuscular injection. All the intramuscular injections may have mild to moderate complications such as pain, focal abscess, nerve complication and anaphylactic reactions. Among these complications, wide necrosis of the skin like Nicolau syndrome happens very rarely. In this condition, Patients typically report acute, intense pain, immediately after drug injection and it is followed by an erythematous macular evolving after 24 hours into a livedoid violaceous patch with dendritic extensions. The study has been reported a case report of a 6-month-old infant who suffered from Nicolau syndrome after the injection of pentavalent vaccine.
Methods: A 6-month-old girl infant without a history of any disease was referred to the emergency department with the signs of erythema, edema and purple like discoloration in the vaccine injection site at the left tight, after vaccination. One hour after admission, in the lower limb severe edema along with an extension of a dark red to purple discoloration happened on different parts of foot and after 5 days they turned necrotic. The infant suffered from Nicolau syndrome after the injection of the pentavalent vaccine.
Conclusion: Although Nicolau syndrome is a very rare complication with no definitive treatment but can be prevented and not be aggravated by doing proper method of intramuscular injection and no application of cold compress (aspiration the needle for 5–10 seconds before injecting to make sure not to hit a blood vessel, the proper method of z-track, holding injection immediately if the patient complains excruciating pain on injection site, appropriate length of the needle to reach muscle, and different sites for multiple injections). However, due to lack of supporting evidence, needle aspiration is not recommended because no major vessel runs through the normal vaccination zone and that faster method is less painful. So, the vaccination must be done in right place with an appropriate length of the needle.

Volume 79, Issue 9 (12-2021)
Abstract
Today surgery is supposed as the cure for many diseases and the fear of post-operation pain burdens stress over the patients. Postoperative pain can, especially if severe, complicate the patient's condition and may lead to chronic postoperative pain. post-operation pain control is effective in the recovery process, hospitalization period and patients’ satisfaction. Insufficient post-operation pain control increases complications and care costs. Local analgesia is one of the components of multimodal postoperative. analgesic protocol to control pain. Local analgesia technique is a simple, accessible and feasible method for various surgeries. The opioid analgesics to control post-operation pain are associated with some complications such as opium addiction, nausea and vomiting, late return of bowel function and social costs. This review study aims. to review previous studies on the effect of injection of analgesic agents in the surgical incision in post-operation pain control. This is a Narrative review study. to related scientific documentaries a search was conducted in Persian and English using the keywords of local injection of the incision site, wound infiltration with analgesic agents and post-operation pain control in Google scholar, PubMed and Scopus database during the years 2000 to 2020. The obtained articles included systematic reviews, Meta-analyses and randomized clinical trials (RCT). We reviewed studies that had utilized single-dose injection of analgesic agents in surgical incisions at the end of surgery to control post-operation pain. A total of ten studies were reviewed. There were 4 studies in the field of laparoscopic gynecological and non-gynecological surgeries, three studies in the field of laparotomy and three review studies. injection of analgesic agents in the surgical incision to control post-operation pain is easily available and does not necessitate any special skill. On the other hand, it is a safe method without further complications and does not increase the duration of surgery. Regardless of the differences in various studies and the kind of analgesic agents, a general reduction in pain severity and consumption of opioid and non-opioid analgesic agents were observed using the injection of analgesic agents in surgical site incision.

Abstract
Background: One of the most important issues for patients with osteoarthritis is reducing pain and returning them to normal life. In addition to losing weight and improving daily activities, pain management treatments may be needed. One of these treatments is the injection of hyaluronic acid gel into the knee joint, which has been studied in this study.
Methods: In this study, 61 patients with knee osteoarthritis were included and the Then, they received the injection of hyaluronic acid gel, and the intensity of pain, range of motion of the knee joint, and inflammation of the knee joint were measured. The numeric rating scale was used to measure pain intensity, and movement angle was used to measure the range of motion
Results: The mean age of patients in this study was 60.52±11.77 years. Pre-injection pain index in patients was 7.90±0.99, which decreased to 5.49±1.91 on the third day, 5.98±1.98 on the seventh day and 3.77±2.91 on the 30th day (P<0.001). The amplitude of painless movement based on the degree before injection in patients was 38.85±19.44 which increased to 60.25±21.65 on the third day to 65.25±22.65 on the seventh day and to 71.07±24.17 on the 30th day (P<0.001). Inflammation rate was reported before injection in 29 patients which decreased to 6 patients on the third day after injection (P=0.009).
Conclusion: Injection of hyaluronic acid into the joint has analgesic effects and significantly improves the function and range of motion of patients. It is recommended that hyaluronic acid could be considered as a suitable drug in the treatment process of these patients. Considering that using this method, which is a useful treatment method in reducing patients' pain and improving their function, we recommend this method, especially in the elderly and without the need for surgery.

Abstract
Background: There are many conservative interventions to reduce the symptoms of coccydynia, but it is not clear which treatment can be more effective. The aim of this review study was to evaluate the types of conservative interventions and the effectiveness of each of them in reducing coccydynia symptoms.
Methods: This systematic review was carried out based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) instruction. A search for research studies published up to October 2021 was conducted in Neuromusculoskeletal Research Center, Firoozgar General Hospital, Iran University of Medical Sciences, Tehran, Iran, using Scopus, Science Direct, Web of Knowledge and Cochrane without data constraints. The search was carried out in October 2021 and continued for seven months. The quality of the articles was evaluated using the Physiotherapy Evidence Database scale (PEDro). All prospective randomized clinical trial studies in which participants suffered from coccydynia  and were treated with nonsurgical treatments  were included.
Results: 945 articles were found in the primary search of the databases. After eliminating 493 repetitive papers, 452 studies remained which were screened by the two researchers of this study in terms of the title and abstract. 40 studies were selected for full-text evaluation. Finally, 12 articles were included in the review study. Two papers used extracorporeal shockwave, two papers used impar ganglion block, three papers manual therapy, and four studies injection. The remaining four studies used iontophoresis with ketoprofen, biofeedback therapy, acupuncture, and physiotherapy with Kinesio taping.
Conclusion: Treatment with extracorporeal shock wave and impar ganglion block significantly improve tailbone pain and show more permanent effects on patients' symptoms. Manual therapies are mostly used in cases where the tailbone is stable. It seems that achieving the desired response requires more than six sessions, which is not pleasant for patients. Injections, especially those performed under fluoroscopic guidance, require high skill in addition to being unpleasant and painful. However, this procedure is done in one session, so there is no need for the next visit.
