Prevalence of Sarcoidosis in the Irish Republic

JOSEPH LOGAN

1. From a total of 383,000 M.M.R. exam- inations in Dublin in 1958, 1959, 1960 and 1962, there was an overall discovery of 33 cases of sarcoidosis per 100,000 ex- aminations.

3. During these years there was no apparent increase in the prevalence. In 135 biopsy-confirmed cases of sarcoid- osis the maximum age-incidence was in the 10-20 age groups (33 yo), and 76 yo under 40 years old. There was no difference between the num- ber of males and females.

2. A preponderance of 5 females to 1 male found in 1958 was not found in later years.

Note: 1. Many of these patients were referred by

their own doctor because of symptoms. The number is unknown.

2. The figures refer to the Dublin area only (predominantly urban),

3. I t has not been found possible to check the diagnosis of sarcoidosis for the years 1958-1960. The figures appear to refer to X-Ray appearances suggestive of sar- coidosis.
