Item Anaesthesia for caesarean section in haemoglobin SC disease complicated by eclampsia: A case report(British Journal of Anaesthesia, 1973-07) Edwards, R.Patients with haemoglobin SC discase rarely manifest serious clinical symptoms except during pregnancy when eclampsia and crisis commonly occur. Such a patient, who developed eclampsia which was treated with chlormethiazole infusion, and who subsequently underwent Caesarean section under general anaesthesia, is described. This case confirms previous experience that careful attention to detail with a straightforward technique is the most important factor for a successful outcome.Item Clinical significance of thiopentone binding to haemoglobin and plasma protein(British Journal of Anaesthesia, 1973-08) Edwards, R.; Ellis, F.R.The minimum dose of thiopentone required to induce anaesthesia was determined bygiving thiopentone incrementally until verbal counting and eyelash reflexes wereabolished. Males required 2.75 mg/kg (±0.11 SE) and females 2.16 mg/kg ( + 0.10 SE)to abolish verbal counting. Thiopentone requirement correlated positively with haemo-globin concentration (P<0.001) but not with plasma albumin, Ol globulin, total globulinor A/G ratio. The presence of sickle-cell haemoglobins did not influence thiopentonerequirements. It is suggested that this result may have clinical importanceItem A study of body temperatures of anaesthetized man in the tropics(British Journal of Anaesthesia, 1977-11) Ellis, F.R.; Zwana, S.L.V.Body core and skin temperatures were measured in 20 African patients undergoing herniorrhaphy in hot and humid conditions; one half of the patients received halothane and the other half received diethyl ether. No difference was found between these two groups. Body core temperatures decreased even with an ambient temperature of 28.7°C and a relative humidity of 72% and all sites reached a new thermal equilibrium at 30 min. It is suggested that the level of the re-established thermal equilibrium is a function of the skin to ambient thermal gradient, which depends on the failure of the countercurrent heat exchange mechanism as a result of redistribution of peripheral blood flow. © 1977 Copyright: Macmillan Journals Ltd.Item The endomorphism ring of pointed separable torsion-free Abelian groups(Journal of Algebra, 1978-12) Webb, M.C.This paper studies the endomorphism rings of separable torsion-free Abelian groups. Baer [l] defined an Abelian group to be separable if given any finite subset of the group there is a complctcly dccomposablc direct summand of the group containing that subset. The endomorphism rings of such groups have attracted the attention of several workers, notably that of Liebert [7] who characterized those rings isomorphic to the endomorphism ring of some separable Abelian p-group. Moreover, Baer [2] and Kaplansky [6] proved that if two torsion Abelian groups have isomorphic endomorphism rings, then the groups themselves are isomorphic. Results corresponding to these have been proven for homogeneous torsion- free Abelian groups, with Metelli and Salce [8] obtaining a characterization of the endomorphism rings of those groups and Hauptfleisch [5] showing that if two such groups have isomorphic endomorphism rings, then they are almost isomorphic. The meaning of “almost” becomes clear in Theorem 3, from which Hauptfleisch’s result follows as a corollary. We consider only torsion-free Abelian groups and any undefined concepts are standard ones from Fuchs [3]. We define a group to be pointed if the set of types of its rank-l summands contains a unique minimal type, when WC say that the group is pointed in that type. We say a group is idempointed if it is pointed in an idempotent type. Clearly homogeneous separable groups are pointed since all elements of the group have the same type and the group has at least one rank-l summand. We characterize the rings isomorphic to the endomorphism ring of someItem Bephenium hydroxynaphthoate in the treatment of hookworm infection in Accra(Annals of Tropical Medicine and Parasitology, 1973) Chinery, W.A.; Anim, J.T.; Ofori Attah, G.; Haddock, D.R.W.No abstract availableItem Traumatic rupture of the thoracic aorta and inferior vena cava: an unusual cause of death at the place of work(Medicine, Science and the Law, 1974) Anim, J.T.; Laing, W.N.No abstract availableItem Malignant lymphoma in Ghana: Part I: A review of surgical material at the Korle Bu Teaching Hospital from 1966 to 1971(Ghana Medical Journal, 1973) Anim, J.T.; Christian, E.C.; Laing, W.N.391 cases of histologically proven lymphoma were reviewed. The incidence rate was 17.5% of all malignant tumors in the series. Burkitt's lymphoma is the most common type of lymphoma in Ghana, followed by reticulum cell sarcoma. Unlike the situation in western countries, the incidence of Hodgkin's disease in Ghana is low, but the age distribution in all the types of lymphoma studied tended to show a higher occurrence in a slightly younger age group than in the U.S.A., Britain or Japan. Sex distribution was about the same as in other studies, but ethnic distribution showed no significant high occurrence in any of the 4 main groups considered.Item Malignant lymphoma in Ghana. Part II: Hodgkin's disease(Ghana Medical Journal, 1973) Anim, J.T.; Christian, E.C.; Laing, W.N.Reclassification of 45 cases of Hodgkin's disease according to the recommendations of the Rye Conference of 1965 has shown a marked preponderance of the mixed cellularity type (78%) in Ghana. This group does not occur more frequently in older patients as suggested by Lukes et al. (1966), but a study is required to correlate this histological distribution of the disease with length of survival, since the mixed cellularity group has been found by other workers to have a poorer prognosis.Item High dose cyclophosphamide in drug resistant and relapsing Burkitt's lymphoma.(Ghana Medical Journal, 1979) Nkrumah, F.K.; Biggar, R.J.Item Acute infectious lymphocytosis.(Lancet, 1973) Nkrumah, F.K.; Addy, P.A.
