Conservative Management of Retroperitoneal Hematoma Expanded to Prerenal Space Due to Episiotomy in a Woman with Vaginal Delivery, a case report.

INTRODUCTION: Episiotomy is a procedure during vaginal delivery to facilitate a safer delivery. However, it can also have complications including hemorrhage, perineal tears, infections, and vaginal hematoma which should be managed and monitored carefully. PRESENTATION OF CASE: A 27-year-old woman with term pregnancy, had a normal vaginal delivery at 39 weeks of gestation, and a large episiotomy was performed due to the estimated neonate weight to prevent shoulder dystocia. She was complicated with a huge pelvic hematoma that was expanded to prerenal space. DISCUSSION: This complication was managed by conservative therapy, including antibiotic therapy, intensive observation of the patient's situation, and follow-up with a CT scan after consulting with a radiologist. The huge hematoma was reduced. CONCLUSION: Noninvasive management and close monitoring for pelvic hematoma due to episiotomy in a low-risk patient are successful; however, consulting with radiologists and experts and a multidisciplinary approach should be considered.

Estimation of Anti-inflammatory and Analgesic Effects of Topical NANOCEN (Nanoliposomal Arthrocen) on Mice.

The purpose of this study was to evaluate the effect of topical application of nanoliposomal avocado/soybean unsaponifiables (NANOCEN) on inflammation inhibition and pain relief in mice. NANOCEN was prepared by the injection method and characterized for vesicle size, charge, entrapment efficiency, in vitro release, and 1-month vesicle stability. The analysis of ASU formulation showed that liposomes had an average size of around 146 nm with a surface charge of - 43 mV. SEM and TEM imaging confirmed the spherical shape of the nanovesicles in ASU formulation. Moreover, ASU nanoliposomes had a high entrapment efficiency (96%) and exhibited significantly (p < 0.0001) sustained release of the drug in vitro model. The topical NANOCEN (ASU 2%) showed robust anti-inflammatory (p < 0.01) and analgesic effect (p < 0.01) superior to ibuprofen 5%. The histopathology of the inflamed tissues confirmed that the topical ASU formulation potentially (p < 0.001) inhibited infiltration of inflammatory cells. Our findings suggest that the topical formulation of NANOCEN may have local applications for pain relief in medicine.

MicroRNA-221 and MicroRNA-222 in Common Human Cancers: Expression, Function, and Triggering of Tumor Progression as a Key Modulator.

MicroRNAs (miRNAs) are a class of short (~22 nucleotides [nt]), single-stranded RNA oligonucleotides that are regulatory in nature and are often dysregulated in various diseases, including cancer. miRNAs can act as oncomiRs (miRNAs associated with cancer) or tumor suppressor miRNAs and have the potential to be a diagnostic, prognostic, noninvasive biomarker for these diseases. MicroRNA-221 (miR-221) and microRNA-222 (miR-222) are homologous miRNAs, located on the human chromosome Xp11.3, which factored significantly in impairment in the regulation of a wide range of cancers. In this review, we have highlighted the most consistently reported dysregulated miRNAs that trigger human tissues to express cancerous features and surveyed the role of those miRNAs in metastasis, apoptosis, angiogenesis, and tumor prognosis. Also, we applied the causes of drug resistance and the role of coordinated actions of these miRNAs to epigenetic changes and selected miRNAs as a potential type of cancer treatment.

Expression Analysis of MicroRNA-222 in Breast Cancer.

BACKGROUND: miR-221 and miR-222 are homologous miRNAs located in tandem, within 1 kb from each other, on human x chromosome. Recent studies declared that microRNA-222 is aberrantly expressed in various malignancies. The goal of this research was to measure the expression level of has-miR-222-3P and reveal its diagnostic and prognostic importance in breast malignancy. METHODS: In this study, 40 pairs of cancerous and matched adjacent non-cancerous breast tissue were collected from patients, and real-time PCR was used to measure the relative expression of miR-222. RESULTS: Our study clarified that microRNA-222 is enhanced in tumor tissues in comparison with normal tissue margins (p ≤ 0.05) and overexpression of miR-222 was not associated with clinicopathological factors such as age, BMI, menopausal status, histological type, grade, stage, tumor size, lymph node metastasis (p > 0.05). The receiver operating characteristic (ROC) curve analysis displayed an optimum cutoff point of < 4.17 to prove that miR-222 is a useful biomarker in breast cancer diagnosis. CONCLUSIONS: Our findings on miR-222 suggest that it could be a potentially useful target for control and management of breast malignancy.

Analysis of miRNA-221 Expression Level in Tumors and Marginal Biopsies from Patients with Breast Cancer (Cross-Sectional Observational Study).

BACKGROUND: miRNA-221 and miRNA-222 are two homologous microRNAs, the high-expression levels of which have been commonly demonstrated in the most current human cancer types as well as breast cancer. The purpose of this research was to determine the clinical value of measuring the expression level of hsa-miR-221-3p in breast cancer tissues and evaluate its biological and prognostic importance in breast cancer (BC). METHODS: A total of 40 tumor samples and matched tumor-free margin specimens were obtained during surgery from patients with BC. After total RNA extraction and cDNA synthesis, the relative expression level of hsa-miR221-3p in tumor and marginal tissues was examined by quantitative real-time PCR. Moreover, the association between hsa-miR-221-3p expression and clinicopathological features of patients was detected. RESULTS: The relative expression level of hsa-miR-221-3p in BC tissues was significantly higher than that in adjacent noncancerous breast biopsies (p ≤ 0.0001). Also, there was no significant association between hsa-miR-221-3p expression with clinicopathological characteristics (p > 0.05). The receiver operating characteristic (ROC) curve analyses also represented an optimum cutoff point of < 4.34 to show that hsa-miR-221-3p is an effective molecular biomarker for BC diagnosis. CONCLUSIONS: This study illustrated that analysis of hsa-miR-221-3p relative gene expression may be applied as a biomarker for screening BC patients and could be a substantial tool in diagnosis and prognosis. Also, that could be advantageous in decreasing surgical mistakes in tumor elimination through the surgery and enhancing all over the progression of surgery with reformed tumor clearance.

The Serum and salivary level of malondialdehyde, vitamins A, E, and C in patient with recurrent aphthous stomatitis.

BACKGROUND: Oral recurrent aphthous stomatitis (RAS) is a chronic inflammatory disease affected oral mucosa which has afflicted about 20% of the society. Etiology of this disease is unknown. Three main factors influencing aphthous stomatitis are genetic, hematologic, and immunologic factors. Another proposed factor that may be considered in etiology of aphthous ulcer is oxidant, anti-oxidant imbalance in the body. The purpose of this study was the evaluation of lipid peroxide enzyme as an important oxidant agent and anti-oxidant vitamins in the saliva and serum of the patients suffering from RAS and compare it to healthy people. MATERIALS AND METHODS: In this cross-sectional, descriptive - analytical study, 25 patients suffering from RAS were compared to 24 healthy individuals. Applying enzyme-linked immunosorbent assay method, the amount of malondialdehyde (MDA) as well as Vitamins A, E, and C were measured in the saliva and serum of two groups. The results were analyzed by Statistical Package for the Social Sciences (SPSS) software version (11.5), t-test and χ(2). RESULTS: No significant difference was detected between salivary and serum levels of antioxidant vitamins (A, E, and C) and MDA in both experimental groups (P > 0.05). CONCLUSION: According to the results of this study, RAS is not associated with oxidant-antioxidant imbalance in the body. However, it seems quite necessary to carry out more studies in this area.
