Opium and alcohol every day consumption can cause people to have many health problems. The present study aimed to assess the effect of ethanol and opium consumption on lipid profiles and atherosclerosis in aorta. Methods Twenty four male golden Syrian hamsters were randomly divided into four treatment groups (n = 6): Control, addicted (40 mg/kg), alcohol (6.0 g/kg) and combination of opium and alcohol. All of the hamsters were scarified and their livers were removed immediately and fixed in formalin solution 10%. The plasma levels of the lipid profiles were measured enzymatically. Aorta sections were examined by a pathologist. Findings The amount of the total cholesterol significantly increased in ethanol (P < 0.05) and combination (P < 0.05) groups, while it had a non-significant decrease in opium group.

Dicer is one of the main regulators of miRNA biogenesis, and deregulation of its expression has been indicated as a possible cause of miRNA alterations observed in various cancers. Our aim was to analyze the expression of the Dicer protein and its relationship with ALL and CLL. This cross-sectional study was performed from 2010 to 2012 in Shahid Faghihi Hospital, Shiraz, Iran. In this study, 30 patients with CLL, 21 patients with ALL, 10 child healthy donors, and 19 adult healthy donors were recruited. The patients’ samples were checked via flow cytometry, immunohistochemistry, and immunocytochemistry. The controls’ samples were also examined in the hematology ward. Total RNA was extracted from the bone marrow and peripheral blood samples of the patients and controls. Then, reverse-transcription polyme...

Histologically CD can be subdivided into a hyaline-vascular variant (CD-HVV), a plasma cell variant (CD-PCV) and an intermediate variant (CD-IV) and further sub-classified into localized unicentric CD (U-CD), and multicentric CD (M-CD). An association with human herpes virus 8 (HHV8) and human immunodeficiency associated virus (HIV) in some CD cases is well documented, though the pathogenesis of CD still remains to be understood (Casper et al. Br J Haematol 2005). In recent years, cytogenetic and molecular studies have demonstrated clonal abnormalities in CD (Fajgenbaum et al. Blood 2017) as well as somatic mutations in follicular dendritic cell sarcoma (FDCS) - a rare clinically aggressive mesenchymal tumor associated with CD-HVV (Griffin et al. Mod Pathol 2015). However, an understanding of the genetic and epigenetic landscape of these rare diseases ...

Cytogenetic analysis of leukemic blasts plays an important role in classification and prognosis in ALL patients. The purpose of this study was to define the frequency of chromosomal abnormalities of ALL patients in adults and children in Fars province, Iran. Methods: In this cross-sectional study, we evaluated karyotype results of bone marrow specimens in 168 Iranian patients with ALL (154 B-ALL and 14 T-ALL) in Fars Province using the conventional cytogenetic G-banding method. Results: The frequency of cytogenetic abnormalities, including numerical and/or structural changes, was 61.7% and 53.8% in the B-ALL and T-ALL patients, respectively. Hyperdiploidy was the most common (32%) cytogenetic abnormality. Among structural abnormalities, the most common was t(9;22) in 11% of the patients. The children showed a higher incidence of hyperdiploidy and lower incidence of t(9;22) than adults (P<0...

The major pathological features of LCH are expression of CD1a and S100 as well as Birbeck granules. Its presentation can differ from a mild bone lesion to a multi-systemic evolved malignant neoplasm; however, the latter outcome is almost rare. Thus, LCH is mostly known as a benign neoplasm. In this study, we present a case of LCH followed by Hodgkin lymphoma (HL). Accompaniment of this disease with malignant lymphoma is rare and considered as case report. Several cases in which malignant lymphoma occurred prior to LCH are reported; however, few cases can be found with LCH followed by malignant lymphomas.

Although, most Lyme disease patients can be cured with a course of antibiotic treatment, a significant percent of patient population fail to be disease-free post-treatment, necessitating the development of more effective therapeutics. We previously found several drugs including disulfiram having with good activity against B. burgdorferi. In current study, we evaluated the potential of repurposing the FDA approved disulfiram drug for its borreliacidal activity. Our in vitro results indicate disulfiram shows excellent borreliacidal activity against both the log and stationary phase B. burgdorferi. Subsequent mice studies have determined that the disulfiram eliminated B. burgdorferi completely from hearts and urinary bladder by day 28 post infection, demonstrating the practical application and efficacy of disulfiram against B. burgdorferi in vivo.

MCD can be further subtyped based on human herpes virus 8 (HHV8) infection into HHV8-associated MCD, HHV8/idiopathic MCD (iMCD), and polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin change (POEMS)-associated MCD. In a subset of cases of UCD, an associated follicular dendritic cell sarcoma (FDCS) may be seen. Although numerous reports of the clinical and histologic features of UCD, MCD, and FDCS exist, an understanding of the genetic and epigenetic landscape of these rare diseases is lacking. Given this paucity of knowledge, we analyzed 15 cases of UCD and 3 cases of iMCD by targeted next-generation sequencing (NGS; 405 genes) and 3 cases of FDCS associated with UCD hyaline vascular variant (UCD-HVV) by whole-exome sequencing. ...

It usually affects abdominal cavity and has a male predominance. Its correct diagnosis and treatment is sophisticated and requires an experienced multidisciplinary team. Hereby we present a 25 yr old man from Kerman Province in 2013 with abdominal mass and ascites who underwent sonography guided percutaneous needle biopsy which was misleading and inconclusive for diagnosis. Thus an open biopsy was fulfilled which revealed solid nests of small round cells with hyperchromatic nuclei and clear cytoplasm surrounded by a desmoplastic stroma suggestive for DSCRT. The diagnosis was confirmed by positive immunohitochemical reaction for cytokeratin, desmin and neuron specific enolase (NSE).Ultimately the patient underwent chemotherapy on the basis of P6 protocol without surgical debulking. Diagnosis and treatment of DSCRT could be a dilemma due to its rarity, various clinicopathologic ...

He presented for many years with a palpable epigastric mass, and recent abdominal pain, early satiety, nausea and vomiting. The mass was a like deformed fetus weighing 815 gr who was anencephalic and deprived of viscera but there was a distinct vascular connection through the right limb. Microscopic examination revealed a normal epidermis with melanocytes overlying dermis with mature adnexa. The fetus plain film after surgery showed a rather complete skeletal system. All above findings were in favor of fetus in fetus, a rare congenital entity in which a nonviable parasitic fetus grows within the body of its twin.

Methods: Handred cases of invasive ductal carcinoma were immunohistochemically investigated for the presence of smooth muscle actin (SMA), ER/PR, HER2, anti-CD34 antibody and microvessel count (MVC). Patients were scored in four different zones of invasive areas: invasive cancer, DCIS, brocystic disease ± ductal intraepithelial neoplasia (FCD ± DIN), and normal tissue. Results: There was a signi cant difference in stromal myo broblasts between all areas except for the stroma of DCIS and FCD ± DIN (P < 0.001). We observed positive signi cant correlations between stromal myo broblasts, HER2 expression, and the numbers of involved lymph nodes in invasive cancer, DCIS, and FCD ± DIN (P < 0.001). More myo broblasts were present in grade III cases, with the least frequent observed among grade I cases in the stroma of those with invasive disease, DCIS, and FCD ± DIN (P < 0.001). MVC was inversely related to stromal myo broblasts in invasive cancer (P < 0.001) and DCIS (P < 0.001), whereas there was a positive correlation in the stroma of FCD ± DIN (P = 0.002) and normal areas (P = 0.054). There was a signi cant difference in MVC observed in all areas except for DCIS and FCD ± DIN (P < 0.001). We noted signi cant inverse correlations between MVC, HER2 expression, and the numbers of involved lymph nodes in invasive cancer and DCIS (P < 0.001). Most MVC were present in grade I, with the least frequent observed in grade III cases in the stroma of invasive cancer, DCIS and FCD ± DIN (P < 0.001). Conclusion: Angiogenesis can be observed before any signi cant myo broblastic changes in the pre-invasive breast lesions. The elevated content of myo broblasts in stroma of tumor; probably may be a worse prognostic factor and the steps from atypical epithelial hyperplasia to DCIS and then to the invasive carcinoma do not appear to be always part of a linear progression.

The STAT family consists of seven genes, STAT1-4, STAT5A, STAT5B and STAT6, that are involved in regulating cellular proliferation, apoptosis, angiogenesis and the immune system response. Constitutive activation of STAT3, via mutational changes, is important in oncogenesis in both solid and hematopoietic cancers. In the case of hematopoietic neoplasms, STAT3 driver mutations have been described in T-cell large granular lymphocytic (T-LGL) leukemia and chronic natural killer lymphoproliferative disorders (CLPD-NK) and are seen in 30%-40% of T-LGL leukemia patients. STAT5B is also mutated in T-LGL leukemia and CLPD-NK, but in a much smaller proportion. Here we review past and current research on STAT genes in hematopoietic and solid cancers with emphasis on STAT3 and STAT5B and their roles in the pathogenesis of hematopoietic malignancies, particularly T-LGL leukemia and CLPD-NK.

It is a rare tumor that can present in nodal and extranodal sites. A 41-year-old woman presented with a 6-week history of an enlarging lump in her neck. Fine needle aspiration (FNA) was performed. FNA findings led to the diagnosis of malignant tumor. We suggested that it was an FDC sarcoma. The tumor was excised. On microscopic examination, the tumor largely replaced the lymph node. It was composed of oval to spindle cells arranged in sheets and interlacing fascicles with a storiform pattern. The tumor cells showed widespread immunopositivity for CD21. Based on these findings the diagnosis of FDC sarcoma was made. Two years later local recurrence occurred. FDC sarcoma has characteristic FNA findings. Once FDC sarcoma is suspected cytologically or histologically, immunohistochemical stains must be performed for reaching the correct diagnosis. Awareness of this rare entity is necessary to avoid its underrecognition.

Clinically, it presents as solitary or multiple subcutaneous nodules, predominantly in the head and neck region, typically in the pre auricular region, forehead, and scalp. The etiology of Kimura disease is still unknown. This disorder should be suspected when the clinical triad of painless unilateral cervical adenopathy, hypereosinophilia, and hyper-IgE is present. We report a case of KD with multiple subcutaneous nodules in the parotid, submandibular and posterior auricular regions, hypereosinophilia and hyper IgE levels.

The aim of this study was to assess the efficacy of inferior alveolar nerve (IAN) block combined with buccal infiltration for mandibular molars with irreversible pulpitis. Methodology. Eighty-four patients were randomly assigned to 3 groups of 28 patients each. Lidocaine 2% with 1:80,000 epinephrine was used for all injections. Group I patients received an IAN block with 1.8 mL of anesthetic. Group II patients received an IAN block using 3.6 mL. Group III patients received 1.8 mL as an IAN block and 1.8 mL as a buccal infiltration. A visual analogue scale was used to rate pain before anesthesia and discomfort experienced before and during access cavity preparation. Data were analyzed by chi-square, ANOVA, Kruskal-Wallis, and Mann-Whitney tests. Results. The success rates for groups I to III were 14.8%, 39.3%, and 65.4%, respectively. Group III had significantly better anesthesia compared with group I (P Ͻ .05).

The STAT family consists of seven genes, STAT1-4, STAT5A, STAT5B and STAT6, that are involved in regulating cellular proliferation, apoptosis, angiogenesis and the immune system response. Constitutive activation of STAT3, via mutational changes, is important in oncogenesis in both solid and hematopoietic cancers. In the case of hematopoietic neoplasms, STAT3 driver mutations have been described in T-cell large granular lymphocytic (T-LGL) leukemia and chronic natural killer lymphoproliferative disorders (CLPD-NK) and are seen in 30%-40% of T-LGL leukemia patients. STAT5B is also mutated in T-LGL leukemia and CLPD-NK, but in a much smaller proportion. Here we review past and current research on STAT genes in hematopoietic and solid cancers with emphasis on STAT3 and STAT5B and their roles in the pathogenesis of hematopoietic malignancies, particularly T-LGL leukemia and CLPD-NK.

It is a rare tumor that can present in nodal and extranodal sites. A 41-year-old woman presented with a 6-week history of an enlarging lump in her neck. Fine needle aspiration (FNA) was performed. FNA findings led to the diagnosis of malignant tumor. We suggested that it was an FDC sarcoma. The tumor was excised. On microscopic examination, the tumor largely replaced the lymph node. It was composed of oval to spindle cells arranged in sheets and interlacing fascicles with a storiform pattern. The tumor cells showed widespread immunopositivity for CD21. Based on these findings the diagnosis of FDC sarcoma was made. Two years later local recurrence occurred. FDC sarcoma has characteristic FNA findings. Once FDC sarcoma is suspected cytologically or histologically, immunohistochemical stains must be performed for reaching the correct diagnosis. Awareness of this rare entity is necessary to avoid its underrecognition.

Clinically, it presents as solitary or multiple subcutaneous nodules, predominantly in the head and neck region, typically in the pre auricular region, forehead, and scalp. The etiology of Kimura disease is still unknown. This disorder should be suspected when the clinical triad of painless unilateral cervical adenopathy, hypereosinophilia, and hyper-IgE is present. We report a case of KD with multiple subcutaneous nodules in the parotid, submandibular and posterior auricular regions, hypereosinophilia and hyper IgE levels.

The aim of this study was to assess the efficacy of inferior alveolar nerve (IAN) block combined with buccal infiltration for mandibular molars with irreversible pulpitis. Methodology. Eighty-four patients were randomly assigned to 3 groups of 28 patients each. Lidocaine 2% with 1:80,000 epinephrine was used for all injections. Group I patients received an IAN block with 1.8 mL of anesthetic. Group II patients received an IAN block using 3.6 mL. Group III patients received 1.8 mL as an IAN block and 1.8 mL as a buccal infiltration. A visual analogue scale was used to rate pain before anesthesia and discomfort experienced before and during access cavity preparation. Data were analyzed by chi-square, ANOVA, Kruskal-Wallis, and Mann-Whitney tests. Results. The success rates for groups I to III were 14.8%, 39.3%, and 65.4%, respectively. Group III had significantly better anesthesia compared with group I (P Ͻ .05).
