[Abreugraphy and the introduction of mass X-ray screening to Norway].

The Brazilian radiologist Manoel de Abreu (1892 - 1962) was the first who succeeded in developing an apparatus suitable for mass radiography of the chest in the fight against tuberculosis. Within a few years, many countries had started to use mass radiography. The German professor Hans Holfelder (1891 - 1944) improved the apparatus and made a transportable version to be used in special buses and in assembly halls.

[Tuberculosis in the Royal Norwegian Navy at the time of the Second World War].

Tuberculosis became a great problem in the Royal Norwegian Navy during the first years of the Second World War (when it operated in allied services mainly from the UK); with the highest incidence (9.6 per 1 000) during the first half of 1943. Main reasons were insufficient medical examination of recruits, crowded living conditions on board (favoured the contagion) and the physical and psychological pressure during sea operations, which may have reduced the immune defence.

[An Enemy of the People--about Dr Harald Engelsen and work-related lead poisoning in Horten].

Little attention was paid to lead poisoning in Norway before 1930. In 1931-33, however, Dr Harald Engelsen, a naval surgeon, reported to the National Insurance Administration more than 40 cases among shipyard workers. The first worker in which he diagnosed lead poisoning had consulted other doctors, but only got a symptomatic diagnosis.
