Myoplasties of the extraocular muscle may cause adhesions between the operated muscle and the adjacent tissues, commonly generating cicatricial strabismus. With the purpose of reducing to a minimum the occurrence of adhesion, the effects of mitomycin C, an antifibrotic agent, were studied in concentrations of 0.008%, 0.02%, and 0.04% applied during intraoperative of myoplasties of the superior rectus muscle of rabbits. Fifty six animals were divided in five groups. During the postoperative, the operated areas were washed with physiological solution. Eye drop instillation to prevent inflammation and bacterial infection were used. The method to analyze the results consisted of clinical and histological evaluation and statistical analyzes. We also evaluated at the same time the amount of basic fibroblast growth factor (FGF-2) by immunohistochemical study. Clinically, more adhesions were found in the eyes of the control group than in the groups of treated eyes. However there was no significant statistics difference between the two groups (P>0.05). Histologically, mitomycin C caused a delayed cicatrization in the mioplastic areas, specially in the group who received the 0.02% concentration. The immunohistochemical showed FGF-2 marking in fibroblasts and macrophages, but between the groups there wasn't no difference. Based on those results, mitomycin C in the utilized concentrations was capable of delaying the cicatrization and consequently avoid the secondary strabismus without undesirable side effects.

Purpose To investigate the effectiveness of intraoperative mitomycin C in pterygium surgery. Methods The effectiveness of intraoperatively administered mitomycin C and the occurrence of postoperative complications were evaluated in 17 patients with two recurrences of pterygium. The authors employed the “bare-sclera technique” and placed a sterile sponge soaked in a 0.02% mitomycin C solution intraoperatively in the episcleral space for 3 minutes. The control group (15 patients) underwent only surgical excision. Patients were followed for 21 to 30 months. Results The pterygium recurred in one (5.9%) of the 17 patients in group 1 and in six (40%) of the 15 controls. Statistical analysis using Fisher's exact test showed a significant (p=0.027) reduction of recurrences of pterygium in the group treated intraoperatively with mitomycin C. No serious complications or side effects arose during the follow-up period. Conclusions Mitomycin C administered intraoperatively can be considered an effective treatment to improve the success rate after surgical excision.

Object Extensive peridural fibrosis after lumbar spine surgery may contribute to poor outcome and recurrent symptoms leading to repeated operation. Secondary procedures are considerably hampered by the presence of scar tissue. Moreover, after excision of the peridural scar, the fibrous tissue may recur, leading to unsuccessful surgical outcome. Mitomycin C (MMC), an alkylating antibiotic substance isolated from Streptomyces caespitosus, potentially suppresses fibroblast proliferation after surgical intervention. The authors investigated the effect of MMC on the reformation of epidural fibrosis in a laminectomy model in rats. Methods Twenty-four Wistar rats underwent a repeated lumbar laminectomy 3 months after the first operation. In 12 rats, MMC in a concentration of 1 mg/ml was locally applied to the laminectomy site. No treatment was performed in the control group of the other 12 rats. All rats underwent clinical evaluation. Mobility ratings and any evidence of neurological deficit were recorded. Twelve weeks after the second operation, the animals were killed for histological examination. The extent of epidural fibrosis and dural adherence was evaluated. All MMC-treated animals showed reduced epidural scarring, compared with the control group. In nine MMC-treated rats (75%), dural adhesions were moderate. In contrast, all control sites showed dense epidural fibrosis with marked dural adherence. No side effects of the treatment were observed. Conclusions In this experimental study, MMC in a concentration of 1 mg/ml locally applied significantly reduced recurrence of epidural fibrosis and dural adhesions without any side effects after repeated spinal surgery in a laminectomy model in rats.

AbstractThis study investigated the inflammatory effect of intraoperative mitomycin C (MMC) on adhesion reformation in human rectus muscles. Ten consecutive patients who underwent medial rectus resection had their postoperative rectus muscles divided into two groups: control group (n = 10) and MMC group (n = 10). In the MMC group, the muscle was soaked for 2 min with MMC, prepared as a 0.2 mg/mL (0.02%) solution. The 0.02% MMC reactions were examined using histological analysis with hematoxylin-eosin (inflammatory response) and Masson's trichrome (collagen fibrils), immunoreactivities of cyclooxygenase-II (inflammatory response), and collagen type I and III, scanning electron microscopy analysis to quantify the diameter and D-periodicity of collagen fibrils, and atomic force microscopy analysis to quantify the diameter, D-periodicity, and adhesion force of collagen fibrils. The rectus muscles treated with 0.02% MMC showed a significantly increased inflammatory response (p < 0.05), increased collagen density (p < 0.0001), increased fibril diameter (p < 0.001 or p < 0.05), and decreased fibril adhesion force (p < 0.005) compared to the rectus muscles in the control group. MMC simultaneously caused an inflammatory response as well as nanostructural and biomechanical property changes in the collagen fibril network.

Introduction: The role of virgin coconut oil in the treatment of allergic rhinitis is controversial. Thus, the aim of the present study is to determine the effects of virgin coconut oil ingestion, in addition to standard medications, on allergic rhinitis. We also studied the side effects of consumption of virgin coconut oil. Methods: Fifty two subjects were equally divided into test and control groups. All subjects received a daily dose of 10mg of loratadine for 28 days. The test group was given 10ml of virgin coconut oil three times a day in addition to loratadine. The symptoms of allergic rhinitis were scored at the beginning and end of the study. Results:, the symptom score were divided into nasal and non-nasal symptom scores. Sneezing score showed a significant difference, however the score was more in control group than test group, indicating that improvement in symptom was more in control group. The rest of the nasal symptom and non-nasal symptom score showed no significant difference between test and control groups. Approximately 58% of the test subjects developed side effects from consumption of virgin coconut oil, mainly gastrointestinal side effects. Conclusion: In the present study, ingestion of virgin coconut oil does not improve the overall and individual symptoms of allergic rhinitis, furthermore it has side effects.

Frontal bone fracture is a common facial bone fracture which commonly involved the outer table part. Most of the time outer table fracture is treated conservatively. However, when there is involvement of orbital wall fracture, as well as entrapment of extraocular muscle, surgical intervention via open reduction and internal fixation is needed. We described a case of outer table frontal bone fracture with left orbital roof fracture complicated with superior rectus muscle entrapment which was successfully treated via open reduction and internal fixation.International Journal of Human and Health Sciences Vol. 02 No. 03 July’18.

Concept Study

Background: The chronic phase of Spinal Cord (SC) injury is characterized by the presence of a hostile microenvironment that causes low activity and a progressive decline in neurological function; this phase is non-compatible with regeneration. Several treatment strategies have been investigated in chronic SC injury with no satisfactory results. OBJECTIVE- In this proof-of-concept study, we designed a combination therapy (Comb Tx) consisting of surgical glial scar removal plus scar inhibition, accompanied with implantation of mesenchymal stem cells (MSC), and immunization with neural-derived peptides (INDP). Methods: This study was divided into three subsets, all in which Sprague Dawley rats were subjected to a complete SC transection. Sixty days after injury, animals were randomly allocated into two groups for therapeutic intervention: control group and animals receiving the Comb-Tx. Sixty-three days after treatment we carried out experiments analyzing motor recovery, presence of somatosensory evoked potentials, neural regeneration-related genes, and histological evaluation of serotoninergic fibers. Results: Comb-Tx induced a significant locomotor and electrophysiological recovery. An increase in the expression of regeneration-associated genes and the percentage of 5-HT+ fibers was noted at the caudal stump of the SC of animals receiving the Comb-Tx. There was a significant correlation of locomotor recovery with positive electrophysiological activity, expression of GAP43, and percentage of 5-HT+ fibers. Conclusion: Comb-Tx promotes motor and electrophysiological recovery in the chronic phase of SC injury subsequent to a complete transection. Likewise, it is capable of inducing the permissive microenvironment to promote axonal regeneration.

Background: The cochlear implant (CI) is a standard procedure for the treatment of patients with severe to profound hearing loss. In the past, a standard healing period of 3–6 weeks occurred after CI surgery before the sound processor was initially activated. Advancements of surgical techniques and instruments allow an earlier initial activation of the processor within 14 days after surgery. Objective: Evaluation of the early CI device activation after CI surgery within 14 days, comparison to the first activation after 4–6 weeks, and assessment of the feasibility and safety of the early fitting over a 12 month observation period were the objectives of this study. Method: In a prospective study, 127 patients scheduled for CI surgery were divided into early fitting group (EF, n = 67) and control group (CG, n = 60). Individual questionnaires were used to evaluate medical and technical outcomes of the EF. Medical side effects, speech recognition, and follow-up effort were compared with the CG within the first year after CI surgery. Results: The early fitting was feasible in 97% of the EF patients. In the EF, the processor was activated 25 days earlier than in the CG. No major complications were observed in either group. At the follow-up appointments, side effects such as pain and balance problems occurred with comparable frequency in both groups. At initial fitting, the EF showed a significantly higher incidence of medical minor complications (p < 0.05). When developing speech recognition within the first year of CI use, no difference was observed. Furthermore, the follow-up effort within the first year after CI surgery was comparable in both groups. Conclusions: Early fitting of the sound processor is a feasible and safe procedure with comparable follow-up effort. Although more early minor complications were observed in the EF, there were no long-term wound healing problems caused by the early fitting. Regular inspection of the magnet strength is recommended as part of the CI follow-up since postoperative wound swelling must be expected. The early fitting procedure enabled a clear reduction in the waiting time between CI surgery and initial sound processor activation.

Abstract Purpose and background Recently, we found that maximal medial rectus recession and lateral rectus resection in patients with complete lateral rectus paralysis resulted in a partial restoration of abduction. In an attempt to understand some of the mechanisms involved with this effect we examined gene expression profiles of lateral recti from these patients, with our focus being directed to genes related to myogenesis. Materials and methods Lateral recti resected from patients with complete lateral rectus paralysis and those from concomitant esotropia (controls) were collected. Differences in gene expression profiles between these two groups were examined using microarray analysis and quantitative Reverse-transcription PCR (qRT-PCR). Results A total of 3056 differentially expressed genes (DEGs) were identified between these two groups. Within the paralytic esotropia group, 2081 genes were up-regulated and 975 down-regulated. The results of RT-PCR revealed that PAX7, MYOG, PITX1, SIX1 and SIX4 showed higher levels of expression, while that of MYOD a lower level of expression within the paralytic esotropia group as compared with that in the control group (p < 0.05). Conclusion The decreased expression of MYOD in the paralytic esotropia group suggested that extraocular muscle satellite cell (EOMSCs) differentiation processes were inhibited. Whereas the high expression levels of PAX7, SIX1/4 and MYOG, suggested that the EOMSCs were showing an effective potential for differentiation. The stimulation resulting from muscle surgery may induce EOMSCs to differentiate and thus restore abduction function.

Abstract Objectives Many women in recent years have been willing to undergo puncture surgery for childbirth, which, like other surgeries, has physical and psychological side effects such as incision, infertility, chronic pain, and anxiety. Therefore, it is important to reduce and improve these side effects. The aim of this study was to determine the effect of foot massage with orange essential oil on pain and anxiety in women undergoing cesarean section. Methods This randomized clinical trial study was conducted in 2019 on 80 women referred to Bahar Shahroud Hospital after cesarean section surgery. The samples were divided into two groups by intervention (foot massage with orange essential oil) and control (foot massage without orange essential oil). The Spielberger scale was used to determine anxiety scores after cesarean section. In the intervention group, the feet were massaged with orange essential oil, and in the control group, the orange essential oil massage was performed without oil. Anxiety before, immediately after, and 60 min after the intervention was measured and evaluated in both groups. Data analysis was performed using descriptive and inferential statistics. Significant levels were considered for all statistical tests (p<0.05). Results The anxiety score before the intervention in the two groups of intervention and control was 57.12 ± 3.12 and 57.07 ± 3.54, respectively, which were not significantly different, but immediately after the intervention, the anxiety scores in both groups decreased significantly so that there was a further decrease in the intervention group (52.10 ± 4.75 and 56.02 ± 3.77), 1 h after the intervention, the anxiety score in the intervention group decreased compared to the previous stage and increased in the control group (50.40 ± 3.74 and 56.85 ± 4.27). Conclusions Foot massage with orange essential oil can probably be effective as a proper nursing intervention in reducing anxiety after cesarean section surgery.

Abstract Background Breast cancer is a global public health issue. The side effects of the clinical treatment can decrease the quality of life of these women. Therefore, a healthy lifestyle is essential to minimize the physical and psychological side effects of treatment. Physical activity has several benefits for women with breast cancer, and Pilates solo and belly dancing can be an enjoyable type of physical activity for women with breast cancer undergoing clinical treatment. The purpose of this study is to provide a Pilates solo and a belly dance protocol (three times per week/16 weeks) for women undergoing breast cancer treatment and compare its effectiveness with that in the control group. Methods The participants will be allocated to either the intervention arm (Pilates solo or belly dance classes three times per week for 16 weeks) or a control group (receipt of a booklet on physical activity for patients with breast cancer and maintenance of habitual physical activity routine). The Pilates solo and belly dance classes will be divided into three stages: warmup and stretching, the main stage, and relaxation. Measurements of the study outcomes will take place at baseline; postintervention; and 6, 12, and 24 months after the end of the intervention (maintenance period). The data collection for both groups will occur with a paper questionnaire and tests covering general and clinical information. The primary outcome will be quality of life (EORT QLQ-C30 and EORT QLQ-BR23), and secondary outcomes will be physical aspects such as cardiorespiratory fitness (6-min walk test and cycle ergometer), lymphedema (sum of arm circumference), physical activity (IPAQ short version), disabilities of the arm (DASH), range of motion (goniometer test), muscular strength (dynamometer test) and flexibility (sit and reach test), and psychological aspects such as depressive symptoms (Beck Depression Inventory), body image (Body Image After Breast Cancer Questionnaire), self-esteem (Rosenberg), fatigue (FACT-F), pain (VAS), sexual function (FSFI), and sleep quality (Pittsburgh Sleep Quality Index). Discussion In view of the high prevalence of breast cancer among women, the implementation of a specific protocol of Pilates solo and belly dancing for patients with breast cancer is important, considering the necessity to improve their physical and psychological quality of life. Pilates solo and belly dancing are two types of physical activity that involve mental and physical concentration, music, upper limb movements, femininity, and social involvement. An intervention with these two physical activities could offer options of supportive care to women with breast cancer undergoing treatment, with the aim being to improve physical and psychological quality of life.
