Serum iron and unsaturated iron-binding capacity in the -thalassaemia trait: their relation to the levels of haemoglobins A, A 2 , and F.
TL;DR: The present study was undertaken in order to obtain information on two points: the serum and unsaturated serum ironbinding capacity levels in normal individuals and in heterozygotes for the ,B-thalassaemia and the relation of serum iron levels to that of haemoglobins A2 and F.

Abstract: Heterozygous f-thalassaemia cannot be differentiated from iron-deficiency anaemia, except by extensive haematological tests. Textbooks of haematology (Harris, 1963; Lehmann and Huntsman, 1966; Wintrobe, 1967) and detailed reviews (WHO, 1967) point out that serum iron is a useful index in differentiating between the two conditions since it is high or normal in the thalassaemia trait and markedly low in iron-deficiency anaemia. Of course this does not apply to individuals in whom both conditions coexist. The frequency of coexisting iron deficiency and the thalassaemia trait is expected to be similar to that of iron deficiency in the general population; this is supported by recent reports indicating that iron metabolism is not disturbed in the thalassaemia trait (Crosby and Conrad, 1964). In Greece, extensive studies have established the high incidence and the geographical distribution of the f-thalassaemia trait (Malamos, Fessas, and Stamatoyannopoulos, 1962; Barnicot et al, 1962/63; Fraser et al, 1964; Stamatoyannopoulos and Fessas, 1964). On the other hand, though iron depletion exists, it has not been thoroughly investigated. Since both the thalassaemia trait and iron deficiency are commonly encountered in Greece, the present study was undertaken in order to obtain information on two points. (1) the serum and unsaturated serum ironbinding capacity levels in normal individuals and in heterozygotes for the ,B-thalassaemia and (2) the relation of serum iron levels to that of haemoglobins A2 and F.

TL;DR: Close monitoring of the maternal and fetal condition during pregnancy is essential, and various treatments, such as blood transfusion or postpartum prophylaxis for thromboembolism, may be indicated.

The heterogeneity of normal Hb A2-beta thalassaemia in Greece.
TL;DR: Nine patients have been observed with homozygous β thalassaemia in each of whom one parent has a normal level of Hb A2 and these families have been divided into two groups on the basis of clinical, haematological and globin chain synthesis studies.

Rapid electrophoresis and quantitation of haemoglobins on cellulose acetate
TL;DR: A rapid and reproducible electrophoretic method for the separation and quantitation of haemoglobins on cellulose acetate is described and blood samples from 32 thalassaemic patients showed haemoglobin A2 values of 3·5% to 7%.

The red cell.
TL;DR: There is no general agreement about the best therapy of myxoedema coma, but common practice to give thyroxine in doses of 0 05 mg daily by mouth combined with triiodothyronine 20 Fg twice daily by intramuscular injection together with hydrocortisone hemisuccinate 50 mg twice daily.

Abstract: The Amphetamines: Toxicity and Addiction by Oriana Josseau Kalant PhD pp xii+151 48s Toronto: University ofToronto Press 1966 London: Oxford University Press No one will deny that the appearance of this monograph is timely. Reports on drug addiction, more or less sensational, abound not only in the lay press but in the medical journals as well. The term is used loosely, opium, heroin, cannabis, the amphetamines and the hallucinogens all tending to fall into the same heap and, as the London Times pointed out recently in a leading article, 'Drugs, searches, sex and the swinging city have been built into one single hateful promotion'. This work by Dr Kalant gives a welcome return to objectivity. It contributes nothing new but, if not quite exhaustive, gives a masterly and succinct review of the knowledge to date. To the medical man it will afford a convenient and readable form of enlightenment on this very controversial subject. Students, too, will learn from it a great deal which may stand them in good stead, as much personally as it will professionally. But, above all, this should be obligatory reading for all those editors, radio and television producers, correspondents and moral arbiters who are so impatient to express themselves without paying sufficient attention to the facts that are available. As far as the amphetamines are concerned, there can be no excuse now. Dare we ask that Dr Kalant and her sponsors, the Alcoholism and Drug Addiction Research Foundation of Ontario, now proceed to deal similarly with the opiates, with cannabis and with the hallucinogens?

Types of thalassaemia-trait carriers as revealed by a study of their incidence in Greece.
TL;DR: The present study was undertaken in order to obtain information on the frequciicy of carriers of the abnormal trait in Greece and to collect data regarding the haematological and biocheniical abnormalities of such carriers in a random sample of the population.
