Agnogenic lymphoid metaplasia of the spleen

A condition of lymphoid metaplasia of the spleen, accompanied by symptoms of hypersplenism arising from an unknown stimulus, is reported. As far as is known, this is the first reported case. The value of splenic and bone marrow puncture in diagnosing splenomegalies of obscure nature is pointed outAnother case was observed as early as the Japanese occupation. But as the chart was destroyed by fire, all reports were lost.(Summary)

Trends in medical education

Several aspects of modern medical education are noted. Among the subjects discussed are: prerequisite for admission in medical schools, medical school as a department of a university, post graduate education, specialism and post graduate school, and the changing medical scene

Further observation on the unusual manifestations of rheumatic disease with report of some cases

On careful analysis of the clinical history of Case IV, we find that the patient from childhood has been having frequent fevers and joints pains and that during the present illness which has lasted for one year previous to admission, aside from the symptoms of cardiac failure and those referable to the lungs due to pulmonary tuberculosis, he had pain and swelling of the joints and also fever. Such clinical history is certainly very suggestive of rheumatic infection. Blood Wassermann was negative, and the autopsy findings including the histological examination of the viscera showed no evidence of syphilitic infection. The absence of Aschoff bodies is not against rheumatic infection inasmuch as they are not always found in the organs affected by rheumatic infeciton and they are especially absent in the chronic stage of the disease. The role played by rheumatic infection in the production of lesion in the aorta and in other arteries is very well recognizedAccording to M.A. Clerc and Noel Daschamps certain infections such as malaria, scarlet fever, typhoid, pneumonia, la grippe, and above all, acute articular rheumatism especially in children are mentioned as causative factors of aneurysm of the arch of the aortaV.P. Sydenstricker speaks of arteritis as one of the complications of rheumatic infection, although he says that arteritis is seldom recognized clinically but it may be suspected when there is tenderness on pressure over superficial arteritis. Aortic lesion due to rheumatic arteritis has been observedMalcolm Goodridge, discussing the diagnosis of syphilitic aortitis, in the Textbook of Medicine by Cecil, 4th edition, 1937, p. 1146, says: the age incidence of syphilitic diseases of the aorta is somewhat helpful in differentiating it from artheroma of the aorta, which is prone to occur in the declining years of life and from rheumatic aortitis which occurs in adolescence or early adult life.

The influence of the American occupation on the life span of the Filipino and on the incidence of degenerative diseases

The first census taken in the Philippines was in 1903, a couple of years after American occupation. The population of the Philippines was then about 7,000,000. The average expectation of life for both sexes was 17.91 yearsThe second census was taken in 1918; the population of the Philippines was then 9,500,000. The average life expectancy for both sexes was 26.59 years. There was an improvement of 8.68 or approximately 9 years. In an unpublished paper which was destroyed in the battle of liberation of Manila, Sison and Lara recall that life expectancy in the Philippines corresponding to 1938 was about 46 years. In other words, from 1918 to 1938 , there was gain of 1 year per year. Based on that average, the life expectancy in 1948 should be about 46 years. In the last census taken in 1948, the population of the Philippines was 19,500,000Incidence of malignant newgrowth from 1908 to 1917 was 2.2 per cent; the incidence in 1938 to 1948 was 5.4 per centIncidence of essential hypertension from 1908 to 1917 was 0.467 per cent; in 1938 to 1948 it was 2.637 per cent.(author)

Cysts of the pancreas: a report of two cases

A case of pseudosyst of the pancreas is reported, demonstrating the successful use of marsupialization. Because of the relative rarity of this condition, special attention is called to the ease with which it can be mistaken for other more common causes of encysted fluids, and to the special means for differentiating it.
