Information and Computer Technology (ICT) has broken national economic boundaries and made the world a global village. Also, many economic integrations bodies have been formed to eliminate all forms of trade and economic barriers. Consequently, consumers have access to more information and products. Competition has, therefore, become more intensive as goods and services providers operate across national and economic barriers...

Population education is one of the dominant themes in social studies education today. This theme is topical in Nigeria, a country that has continued to contend with the problems of uncontrolled population growth. It is a relatively new field of knowledge arising from a realization of problems associated with the rapidly rising world population. The aim of this paper is to look at the various cultural issues that might pose a problem to population education and how such issues can be managed effectively to enhance the quality of living among the Nigeria people.

Abstract
Objective: Although the calibre of the airway is kept patent by multifactorial control system, there is evidence that the calibre of the bronchi varies with time of the day in normal subjects. Asthma is now known to be a chronic inflam¬matory disease and this chronic in-flammation causes hyperreactivity and lability in the airway. Therefore, asthma is characterised as a disease where respiratory symptoms are based on large variation in airway calibre leading to variations in resis¬tance to airflow over a short period of time.

Reported cases of diphtheria from Nigeria have been reducing since the beginning of the millennium even though coverage with diphtheria, pertussis, tetanus (DPT) vaccine has only been low to moderate. Accordingly only sporadic cases of diphtheria have been managed in the past in our hospital. However the occurrence of five cases in the period of one year raises questions on the status of diphtheria control in Nigeria. We present the clinical and sociodemographic features of the cases and discuss the implications of a rising incidence of diphtheria.

Introduction: Diphtheria had been a major of cause of childhood mortality until the advent of an effective vaccine. Even in Nigeria with low to moderate coverage with the third dose of DPT the number of reported cases of diphtheria had been reducing. However, in a recent report we noted an increase in the incidence of diphtheria. The mainstay of management of diphtheria is the Diphtheria antitoxin. Diphtheria antitoxin is not available in Nigeria. We present the mortalities from diphtheria to highlight the need to stock the diphtheria antitoxin.

Banked blood is a limited resource in Nigeria. We sought to evaluate factors that may further limit the effective utilisation of donor blood in a tertiary hospital in Benin City. The records of the blood transfusion unit of the hospital were studied to identify the methods of blood procurement and utilisation from January 1, 2000 to December 31, 2002. A total of 11,021 units of blood were received in the blood transfusion unit within this period out of which 1491 (13.5%) donor blood samples were found unfit for transfusion and, hence, discarded.

One of the objectives of the National Policy on Education is to use education as an instrument for transforming Nigeria into a self-reliant and technologically developed nation, where equal educational opportunities for all citizens at primary, secondary and tertiary levels will be ensured. It also recognises the importance of the integration of individuals, particularly those with special educational difficulties, since these handicapped children are eventually expected to live in the society.
