Background. Studies have reported that obesity has an adverse effect on iron metabolism. Obesity is characterized by chronic, low-grade, systemic inflammation and anemia of chronic disease with elevated serum ferritin and decreased level of serum iron, transferrin saturation, and hemoglobin. Therefore, we examined the association of body mass index with hemoglobin concentration and iron parameters in this study. Methods. This cross-sectional study was conducted in Yazd to assess the relation of body mass index with hemoglobin and iron parameters among 406 adult patients 18–65 years old. Diabetes and conditions that could influence body iron stores were excluded. Results. There is no difference in hemoglobin concentrations, MCV, serum iron, TIBC, transferrin saturation index, and ferritin between normal weight, overweight, and obese persons. Conclusion. Nutritional status of persons and intake of high iron foods by obese persons should be considered. Also, other inflammatory markers should be evaluated in the future studies.

-Background -Celiac disease is an immune-mediated enteropathy due to a permanent sensitivity to gluten in genetically susceptible people. Iron-deficiency anemia is the most widely experienced anemia in humans. Iron-deficiency anemia additionally is a common extra intestinal manifestation of celiac disease. Objective -To investigate correlation between tTg levels and histological alterations and then to determine the prevalence of celiac disease in Center and South area patients of Iran with iron deficiency anemia. Methods -A total of 402 patients aged 12-78 years who presented with iron-deficiency anemia were included in this study. Hemoglobin, mean corpuscular volume and serum ferritin were determined. Venous blood samples for anti-tissue transglutaminase antibody immunoglobuline A and G were obtained from these patients. Upper gastrointestinal endoscopy was recommended to patients who had positive serology.

SummaryPrimary malignant lymphoma of the female genital tract is an extremely rare clinical entity. We report a case of primary non-Hodgkin lymphoma of the uterine cervix. An 85-year-old woman presented with abnormal genital bleeding. A colposcopic examination revealed a mass in the uterine cervix. No other lesions were detected by the whole-body CT, gallium scintigraphy and bone marrow examination. The histological examination and immunohistochemical staining of the cervical biopsy material confirmed a diagnosis of diffuse large B cell lymphoma of the uterine cervix, clinical stage 1E (according to the Ann Arbor Staging Classification for Lymphomas). The patient was treated with rituximab, cyclophosphamide, hydroxydaunorubicin, vincristine (oncovin) and prednisone. Her family refused surgery and involved field irradiation. She was in good condition but after 5 months she expired due to myocardial infarction. BACKGROUND

Background:Bacterial bloodstream infections are one of the most common complications in cancer patients under treatment. Bacteremia in these patients is a medical crisis that needs antibiotic treatment. The aim of this study was to determine bacterial spectrum and antimicrobial resistance pattern in febrile neutropenic cancer patients.Methods:In this prospective study, 212 cancer patients with febrile neutropenia who were referred to Shahid Sadoughi hospital in Yazd from 2012 to 2015 were participated. Bacterial pathogens isolated by the BACTEC media and antimicrobial susceptibility tests performed according to Clinical and Laboratory Standards Institute (CLSI) guidelines.Results:The mean age of patients was 43.5 ± 24.98 years old. Out of 212 participants, 62.3℅ (132/212) were suffering from hematologic malignancies, and 37.7℅ (80/212) had solid tumors. Gram-negative bacteria were the predominant microorganisms (84.9℅). E.coli was the most frequently isolated pathogen (38.68 %), followed by Klebsiella (14.15℅) and Acinetobacter species (11.32℅). In addition, Staphylococcus epidermidis was the most common isolated Gram-positive bacteria (8.5℅). Gram-negative bacteria were susceptible to ciprofloxacin with a response range of 53.7% to 100%. The majority of E.coli isolates were sensitive to ceftazidime (87.8℅) and were resistance to Co-trimoxazole (15.8℅). Klebsiella isolates were 100% susceptible to cephalosporins, meropenem and imipenem.Conclusion:The majority of bacterial pathogens were resistance to various antibiotics. Judicious use of antibiotic therapy can prevent the emergence and spread of antibiotic-resistant Gram-negative bacteria.

In this paper, a wearable, battery-powered, low-power, low-size, cost-efficient, fully programmable neural stimulator is presented. The system comprises a wearable stimulator module and an external controller. To receive the settings required for the operation of the system, the wearable module is programmed through wireless connection to the external controller. Implemented using off-the-shelf components, the wearable neural stimulator weighs 60 g and measures 9 cm × 5 cm × 2 cm. The system is capable of generating independent biphasic stimulations on 8 channels with programmable amplitudes and timings. The neural stimulator consumes about 1.5 mW in the power-down mode and about 51.2 mW in the active mode when all the 8 channels are active. For in-vivo experiments, the system was used to stimulate motor cortex of an anesthetized rat fixed in a stereotaxic instrument.
