Risk factors are largely unknown however, although several biomarkers have been identified which may support development, angiogenesis and invasion of tumor cells. One of these biomarkers is PAI-1. 4G/5G and A-844G are two common polymorphisms in the gene promotor of PAI 1 that may be related to high transcription and expression of this gene. Studies have shown that the prevalence of the 4G and 844G allele is significantly higher in patients with some cancers and genetic disorders. Materials and Methods: We here assessed the association of 4G/5G and A-844G polymorphisms with glioblastoma cancer risk in Iranians in a case-control study. All 71 patients with clinically confirmed and 140 volunteers with no history and symptoms of glioblastoma as control group were screened for 4G/5G and A-844G polymorphisms of PAI-1, using ARMS-PCR. Genotype and allele frequencies of case and control groups were analyzed using the DeFinetti program. Results: Our results showed significant associations between 4G/5G (p=0.01824) and A-844G (p = 0.02012) polymorphisms of the PAI-1 gene with glioblastoma cancer risk in our Iranian population. Conclusions: The results of this study supporting an association of the PAI-1 4G/5G (p=0.01824) and A-844G (p = 0.02012) polymorphisms with increasing glioblastoma cancer risk in Iranian patients.

OBJECTIVE: To assess expressions of CYTOR and CDKN2B in breast cancer and adjacent samples and find their relevance with clinical data. METHODS: We enumerated expression level of CDKN2B and CYTOR in 43 newly diagnosed breast cancer samples and their adjacent specimens using real-time PCR method Expression data was judged using Wilcoxon matched-pairs signed rank test. RESULTS: CYTOR level was higher in tumors compared with adjacent tissues. Nevertheless, there was no difference in expression of CDKN2B between these two sets of tissues. ROC curve analysis showed that CYTOR levels can differentiate between tumoral and adjacent tissues with AUC, specificity and sensitivity values of 0.65, 37% and 92% (P= 0.017). There was a positive correlation between expression levels of CYTOR and CDKN2B genes in breast cancer tissues (r= 0.5 and P= 0.0008) as well as adjacent tissues (r= 0.79 and P< 0.0001). Relative expression level of CDKN2B in normal tissues was associated with clinical stage (P= 0.014). Moreover, relative expression level of CDKN2B in tumor tissues was associated with the body weight. There was no other association between expressions of CYTOR and CDKN2B and clinical or pathological variables. CONCLUSIONS: Cumulatively, this study offers evidence for involvement of these genes in the pathoetiology of breast cancer.

Physical examination revealed multiple, widespread, round, atrophic patches ranging from 3 to 10 cm in diameter with wrinkles and depressed skin (Figure 1). No clear history of previous trauma was found, and her mother mentioned that the lesions appeared spontaneously. The lesions were asymptomatic and were not preceded by erythema. The patient had a long history of multiple admissions for recurrent, treatmentresistant pneumonia. Lung biopsy was performed, revealing fibrous tissue with multiple nonnecrotizing granulomas compatible with chronic granulomatous disease (CGD). A skin biopsy of the buttock lesion was obtained (Figure 2).

This study was conducted to detect differentiating features of these two disorders with IHC analysis of T-cell subsets in the inflammatory infiltrates of alopecia areata and androgenetic alopecia. Methods: This cross-sectional study was conducted at Shohadae-Tajrish Hospital in 2018. Twenty-eight cases of alopecia areata and 32 androgenic hair loss cases were evaluated. H&E and IHC staining for CD3, CD4, and CD8+ T-lymphocytes were performed. Lymphocytic densities were graded in a quintet grading system. The inflammation density in various areas of skin tissue was evaluated. Statistical analysis was performed using SPSS version 21. Results: Peribulbar lymphocytic infiltration was seen in 88.5% of AA patients and 12.5% of AGA patients (P = 0.000). Presence of melanin, pigmented casts, and lymphocytes in follicular stela were in favor of AA diagnosis. CD3, CD4, and CD8+ T-cells in follicular stela, peri-bulbar, and subcutaneous regions were higher and denser in AA patients, while CD3 and CD4+ T-cells around sebaceous ducts were in favor of AGA diagnosis. Conclusion: Peribulbar lymphocytic infiltration is among the most important differentiating features of AA and AGA. Infiltration of T-cells in various regions of skin tissue has high diagnostic value. Histologic and immunohistochemical evaluation of skin tissues according to these factors can differentiate these two entities with high precision.

Due to the importance of microRNAs and HIF1α gene that is involved in the angiogenesis and growth of tumor cells, this study aimed to evaluate the correlation of the expression of HIF1α gene with miR-148a, miR-31, and miR-221, which were reported by in silico analysis as risky microRNAs in GBM. The ndings obtained from Real-Time PCR using TaqMan Assay indicated the signi cant difference in the expression of HIF1α gene and microRNAs between the patient and healthy groups and the expression changes were obtained point to point in the patients; so they can be considered as important biomarkers in glioblastoma. The obtained AUC from the ROC analysis indicated that the analysis of the expression of HIF1α and miR-148a, miR-31 & miR-221 genes can be used to distinguish healthy and patient groups nevertheless, the correlation of HIF1α gene expression with the microRNAs was reported low according to Pearson's correlation coe cient. Thus the signi cant increase in HIF1α gene expression is probably controlled by other molecules. By using bioinformatics analysis; Gene Ontology biological process; MSigDB Hallmark and KEGG pathway enrichment analysis of PPI network was carried out with Enrichr web-based application. The axon guidance pathway, proteoglycan in cancer and some of intracellular signaling pathways identi ed as the most important signaling pathways. The results of MSigDB_Hallmark pathway enrichment analysis introduced hypoxia signaling pathway with less involvement from these micoRNAs. Therefore these microRNAs can be considered in Glioblastoma cell in ltration through the myelinated nerve bers of white matter tracts.

With the increasing incidence of gastric and colorectal cancers and the increased usage of targeted therapies, some cutaneous adverse effects may become common. An 84-year-old male presented to our clinic with multiple ulcerative plaques covered with hemorrhagic crusts on both extremities after several FOLFOX chemotherapy sessions for gastric cancer and liver metastasis. Two weeks later, multiple bullae also appeared, especially on the acral areas. The histopathology examination was compatible with acute leukocytoclastic vasculitis. The FOLFOX chemotherapy regimen is increasingly administered considering the rising incidence of gastrointestinal cancers. Hence, our understanding of its possible side effects and complications must be heightened.

Cutaneous small vessel vasculitis is most often idiopathic but may be aggravated by secondary causes, such as inflammatory conditions, infections, neoplasms, and drugs exposure.Herein, we describe two patients with a long history of rheumatoid arthritis (RA) treated with methotrexate (MTX) for more than ten years, who later developed generalized LCV with pancytopenia after a viral infection, one with herpes simplex virus, and the other with SARS-CoV-2 virus. Because of the worldwide use of MTX in treatment of RA, strict follow-up and preventive measures are needed nowadays, especially during COVID-19 pandemic, in order to avoid any infection which may provoke LCV with or without systemic manifestations. So, using MTX for treating RA or other similar disorders may be considered a double-edged sword, especially during COVID-19 pandemic.

Research paper thumbnail of Losartan treatment improves recessive dystrophic epidermolysis bullosa: A case series

The repetitive wound healing processes lead to extensive cutaneous scarring. The scarring is driven by inflammatory processes, particularly the TGF-β signaling pathways, resulting in excess synthesis and deposition of the extracellular matrix, especially collagen. There is currently no effective or specific treatment for RDEB. Losartan, an angiotensin II type 1 receptor antagonist, is an inhibitor of TGF-β activity. Previous preclinical studies with hypomorphic Col7A1 mice recapitulating features of RDEB have suggested that losartan may improve the clinical features of RDEB. In this case series, we assessed the effects of losartan on the clinical and histopathologic features in seven patients with RDEB; three females and four males; ages 18.1 ± 9.1 years. The diagnosis was based on characteristic clinical features and the presence of biallelic loss-of-function mutations in COL7A1. Daily oral administration of losartan (0.7 mg/kg) for six weeks resulted in subjective improvement of the clinical features, as judged by the treating physicians and the patients, and the severity of the disease objectively improved based on Birmingham Epidermolysis Bullosa Severity (BEBS) score (30.1 ± 12.8 vs. 23.3 ± 10.4, before and after treatment, p = 0.018), accompanied by improvement of quality of life, as determined by the EB-QoL questionnaire (24.0 ± 8.1 vs. 17.7 ± 5.5, p = 0.018). Histopathology of the selected lesions revealed increased number of mast cells, and enhanced microvasculature in the mid and lower dermis. The width of collagen bundles in dermis was suggested to be decreased in four samples and changed from dense to loose in appearance. In summary, this case series reports beneficial effects of losartan on RDEB as a potentially novel treatment. This article is protected by copyright. All rights reserved.
