This retrospective study aimed to describe the magnitude of false positive screening for thalassemia in a primary care setting of Thailand. The study was conducted from 1999 to 2008 and analyzed 13,745 positive cases. It involved a combination of one tube osmotic fragility (OF) and dichlorophenol indophenol (DCIP) precipitation tests. The number of cases increased over the ten-year period, corr...

THE UPTAKE OF GASES SUCH AS OXYGEN, CARBON MONOXIDE, OR NITRIC OXIDE BY THE ERYTHROCYTE INVOLVES: (a) diffusion across the cellular membrane, (b) intraerythrocytic diffusion, and (c) chemical combination with hemoglobin. The aim of this investigation was to obtain data which would permit an analysis of each of these factors in limiting the rate of gas uptake. The initial over-all rate of uptake...

Phenytoin is indicated for tonic clonic seizures and status epilepticus. Phenytoin is known to deplete vital nutrients such as calcium, folic acid, vitamin D, vitamin K, biotin, carnitine, copper, selenium and zinc. Depletion of nutrients is known to cause adverse effects such as ataxia, nystagmus, lethargy, slurred speech and hematological disturbances. Spirulina is a rich source of vital nutr...

We present a case of a 40-year-old female from Turkey, who was referred to our outpatient clinic for an undetermined thalassemia and sickle cell trait. At first consultation hemoglobin was decreased (71 g/L) with microcytosis (MCV 55.1 fL), and hypochromia (MCHC 239 g/L). The patient had severe iron deficiency. Brilliant cresyl blue staining showed >50% of the erythrocytes with typical Hemoglob...

BACKGROUND this study reports on the effectiveness of sitagliptin in Asian Indian type 2 diabetes patients seen at a tertiary diabetes care center who had inadequate glycemic control with oral hypoglycemic agents either alone or in combination, compared to a group of patients who received insulin glargine. PATIENTS AND METHODS patients with type 2 diabetes mellitus (n = 2,817) whose glycemia ...

This paper discusses a current misinterpretation between different parameters of hemoglobin concentration measurement and its amplification under conditions of blood loss. The paper details the distinction between microcirculatory hematocrit and the hematocrit of the macrocirculation to analyze clinical use of real-time patient hemoglobin concentration measurement by noninvasive point-of-care d...

OBJECTIVE To investigate the efficacy of a single dose of inhaled budesonide as compared to oral prednisone in patients with acute asthma. METHODS Randomized double-blind, double-dummy and placebo-controlled clinical trial. Forty-nine children aged 2 to 7 years with acute asthma were randomized in three groups after receiving nebulized salbutamol (0.15 mg/kg). Group I received placebo both as...

Hemoglobin in solution augments the rate of steady state diffusion of oxygen. The flux of oxygen exceeds the diffusive flux by an amount, the facilitated flux, which is constant for a given hemoglobin concentration and is invariant with changing oxygen tension. The facilitated flux is inversely proportional to the length of the diffusion path. Facilitation decreases with increasing molecular si...

Hemoglobin K-Woolwich (Hb KW) is a rare hemoglobin variant with very few cases reported. It is most prevalent in West African countries, particularly Nigeria, Ghana, and the Ivory Coast. Some reports suggest Hb KW may be a clinically benign trait, whereas others indicate it may behave similarly to a β+ thalassemia. The combination of hemoglobin S and hemoglobin KW (Hb S/KW) is a rare double het...

Background: Glucose-6 phosphate dehydrogenase (G6PD) deficiency is the most common inherited enzyme deficiency of red blood cells involving the enzyme pathway of hexose monophosphate. This study was conducted to examine the effect of vitamin E and folic acid on the improvement of acute hemolysis caused by the G6PD deficiency in patients referred to 17 Shahrivar Hospital, Rasht. Materials and M...
