Background: Studies on the hematologic toxicity of ethylene glycol ethers in humans are limited. Therefore, the aim of this study was to examine the association between exposure to solvents (containing 2-butoxyethanol and 2-ethoxyethanol) and hematological effects. Methods: Thirty-four screen-printing workers who were exposed to 2-butoxyethanol and 2-ethoxyethanol and 37 non-exposed clerical workers were selected using data from the health care facilities that provided regular health screening services...

Micro-doping with testosterone (T) is challenging to detect with the current doping tests. Today, the methods available to detect T are longitudinally monitoring of urine biomarkers in the Athlete Biological Passport (ABP) and measuring the isotopic composition of excreted biomarkers to distinguish the origin of the molecule. In this study, we investigated the detectability of a single dose of 100 mg T gel in 8 healthy male subjects. We also studied which biomarkers were most sensitive to T gel administration, including blood biomarkers...

Referral to hematology for anemia is common. In paroxysmal nocturnal hemoglobinuria (PNH), cells deficient in the glycosylphosphatidyl inositol (GPI) anchor are lysed by complement. Eculizumab improves overall survival and quality of life while reducing hemolysis, transfusion requirements, and thrombosis. We evaluated the frequency of screening for PNH in patients with unexplained anemia. Key clinical features, laboratory data, and investigations were recorded for patients referred for anemia since 2010, without a specific cause found...

BACKGROUND: In endurance sports, stress, dehydration and release of chemical factors have been associated with red blood cell (RBC) alterations of structure and function, which may contribute to sports anemia, a well-observed phenomenon during long-distance running. Until now, the investigation of the changes of viscoelastic properties of RBC membrane, a decisive factor of RBC deformability to avoid hemolysis, is lacking, especially in an Oriental population. METHODS: nineteen runners were prospectively recruited into our study...

An 80-year-old male presented with dyspnea on exertion for at least two months. He also complained of progressive dysphagia and weight loss of 35 pounds over the last eight months. Initial blood tests showed hemoglobin of 6.1 g/dl, reticulocytes count of 19.7%, total bilirubin of 3.2 mg/dl, lactate dehydrogenase of 600 U/L, and haptoglobin of less than 8 mg/dl, and direct Coombs test was positive for warm immunoglobulin G. The impression was autoimmune hemolytic anemia (AIHA). The evaluation of dysphagia with esophagogastroduodenoscopy revealed a single irregular 4 cm malignant appearing ulcerated mass at the incisura angularis of the stomach...

After age 85, upper and lower gastrointestinal (GI) endoscopy may be indicated in 5% to 10% of inpatients, but the risk-benefit ratio is unknown. We studied patients older than 85 years undergoing upper and lower GI endoscopy.We analyzed a retrospective cohort of inpatients older than 85 years between 2004 and 2012, all explored by upper and complete lower GI endoscopy. Initial indications, including iron deficiency anemia (IDA), other anemias, GI bleeding, weight loss, and GI symptoms, were noted, as were endoscopy or anesthesia complications, immediate endoscopic diagnosis, and the ability to modify the patients' therapeutics...

Chrysin (CH) is a natural flavone which possesses antioxidant, anti-cancer, and anti-inflammatory properties. The aim of the present study was to investigate the effects of CH on biochemical parameters, histopathological changes, and genotoxicity and hematological indices in diazinon (DZN)-induced toxicity in BALB/c mice. We induced sub-acute toxicity in mice using DZN (20 mg/kg/day) and treated them with CH at the 12.5, 25, and 50 mg/kg/day five times/week in 28 days. In our study, DZN increased lipid profile and liver function tests (LFTs) and creatinine (Cr) but decreased the red blood cell acetylcholinesterase (RBC-AChE) activity and glucose level...

Background: High-altitude headache (HAH) is a notably common disorder affecting the daily life of travelers ascending to high altitude. Hematological parameters are important clinical examinations for various diseases. Today, hematological characteristics of HAH remain unrevealed. Above all, we aimed to ascertain hematological characteristics and independent risk factors/predictors associated with HAH before and after exposure at 3,700 m. Methods: Forty five healthy men were enrolled in present study. Demographic and clinical data, physiological and hematological parameters were collected 3 days before the ascent and after acute exposure at 3,700 m...

BACKGROUND: Blood test results required for the evaluation of anemia are considered difficult to interpret after red blood cell transfusion. However, this hypothesis is neither supported by a strong physiological rationale nor is it evidence based. METHODS: We conducted a prospective multicenter study to compare the values of key assays before and after a course of red blood cell transfusion in the emergency or internal medicine units in four university hospitals...

The objective of the study was to determine the causes and the severity of anaemia in pet rabbits (Oryctolagus cuniculus), to classify anaemia and to compare the reticulocyte counts from healthy and anaemic rabbits. Over a time period of 11 years (2000-2011) a retrospective and prospective study of 223 pet rabbits was performed. Based on the clinic's own reference range for healthy pet rabbits (packed cell volume [PCV] levels 0.33-0.45 l/l), animals with a PCV level below 0.33 l/l were considered anaemic...

In doping control laboratories, autologous blood transfusions are currently detected using an indirect method that monitors changes in an athlete's hemoglobin concentration [Hb] and reticulocyte percent (Ret%) over time. The method is limited by the need for a phlebotomist to collect venous blood and the limited blood stability which requires temperature-controlled shipment and analysis within 72 hours. These limitations significantly reduce the number of samples collected from each athlete and thus the utility of the method...

Avian mortality events are common following large-scale oil spills. However, the sublethal effects of oil on birds exposed to light external oiling are not clearly understood. We found that American oystercatchers (area of potential impact n = 42, reference n = 21), black skimmers (area of potential impact n = 121, reference n = 88), brown pelicans (area of potential impact n = 91, reference n = 48), and great egrets (area of potential impact n = 57, reference n = 47) captured between 20 June 2010 and 23 February 2011 following the Deepwater Horizon oil spill experienced oxidative injury to erythrocytes, had decreased volume of circulating erythrocytes, and showed evidence of a regenerative hematological response in the form of increased reticulocytes compared with reference populations...

INTRODUCTION: Despite the demonstrated efficacy of hydroxyurea therapy, children with sickle cell anaemia in the UK are preferentially managed with supportive care or transfusion. Hydroxyurea is reserved for children with severe disease phenotype. This is in contrast to North America and other countries where hydroxyurea is widely used for children of all clinical phenotypes. The conservative UK practice may in part be due to concerns about toxicity, in particular marrow suppression with high doses, and growth in children...

A 41-year-old woman treated with isoniazid (INH) for latent tuberculosis infection and an oral corticosteroid for sarcoidosis developed severe anemia two months after initiating INH. A bone marrow examination showed erythroblastopenia, and a diagnosis of INH-induced pure red cell aplasia (PRCA) was made. Her reticulocyte count and hemoglobin levels improved two weeks after discontinuation of INH. A literature review of INH-induced PRCA shows that it occurs very rarely in the context of autoimmune disorders...
