Decreased mortality among relatives of patients with systemic lupus erythematosus.

The authors studied mortality among 2513 relatives of 56 Japanese patients with systemic lupus erythematosus. The observed deaths in 142 relatives were compared with the expected number of deaths. The observed number of deaths was significantly less among relatives of patients with systemic lupus erythematosus (p less than 0.01). Deaths from malignant neoplasms and senility (senescence) were significantly lower than the expected number of deaths among relatives (p less than 0.05).

Cancer and other causes of death among female beauticians.

A retrospective cohort study was done of the mortality between 1953 and 1977 among 7,736 Japanese female beauticians who were registered from 1948 to 1960 in Fukuoka Prefecture, Japan. Mortalities from tuberculosis, heart disease, accidents, and all causes were significantly decreased as compared with the mortalities of general population in the prefecture. Observed deaths from all cancers combined were almost equal to those expected (148 observed vs. 139.26 expected). Among site-specific cancers studied, only slightly increased mortality from stomach cancer was statistically significant (61 observed vs. 45.59 expected). No measurable excess mortality was observed for the other sites of cancer.

Respiratory cancer among copper smelter workers: recent mortality statistics.

A survey of mortality among copper smelter workers in the western United States revealed that a respiratory cancer excess previously observed during the period 1938 through 1963 continued from 1964 through 1977. When analyzed in relation to smelter employment prior to 1964, the recent increase in respiratory cancer was linked to work in plant areas where airborne arsenic concentrations were elevated and to a cumulative arsenic exposure index, although some excess risk was also associated with long-term employment in jobs with limited exposures to arsenic. The arsenic-related excess remained after adjustment for work in areas of the plant with elevated concentrations of sulphur dioxide, which was not found to have an independent influence upon cancer risk. Increased rates for nonmalignant respiratory disease were also observed, but were not significantly associated with arsenic exposure.

Cancer and other causes of death among leprosy patients.

A follow-up study was done on the mortality from 1956 to 1975 among 2,383 Japanese patients with leprosy who were admitted to a leprosarium in Japan. The leprosy was classified into two types: lepromatous and tuberculoid. Irrespective of the type of leprosy or the sex of leprosy patient, mortalities were increased from tuberculosis, pneumonia and bronchitis, nephritis and nephrosis, and from total causes. The suicide rate was high among female patients. Deaths from total malignant neoplasms were higher than expected among patients with lepromatous leprosy for both sexes (49 observed vs. 44.02 expected), whereas they were lower than expected among patients with tuberculoid leprosy (35 observed vs. 36.83 expected); however, the differences were not statistically significant. Mortalities from cancers of the cervix and the esophagus among females with lepromatous leprosy were significantly higher. The risk of lymphoreticular cancers was not increased.

Four autopsy cases of neonatal giant cell hepatitis died suddenly and unexpectedly from intracranial hemorrhage.

The authors present four cases of neonatal giant cell hepatitis who died suddenly and unexpectedly from intracranial hemorrhage, autopsied recently at the Tokyo-to Medical Examiner Office. This series consisted of one male and 3 female infants ranging from 37 to 52 days of age. The cause of death of all cases was thought to be massive intracranial hemorrhage. Referring to the connection between intracranial hemorrhage and neonatal giant cell hepatitis, it was assumed that the former must have occurred due to the hemorrhagic tendencies of the latter, superimposing to the hemorrhage at birth trauma of the head. As to the formation of multinucleated giant cell, it is considered to be of degenerative nature of hepatocytes, i.e. the giant cell is formed by fusion of hepatocytes as a result of the disappearance of bile canaliculi, although the etiology of this hepatitis is still unknown.

A cohort study on mortality from cancer and other causes among workers at a metal refinery.

A non-concurrent prospective study was made on deaths from cancer and other causes occurring among 2,675 male workers at a metal refinery from 1949 to 1971. The expected number of deaths computed by applying age- and cause-specific death rates of Japanese males to these workers was compared with the observed number of deaths. Among 839 copper smelters, significantly increased mortalities were noted for lung cancer (SMR = 1,189) and colon cancer, but nor for cancer of the stomach, liver (primary) and biliary passages, pancreas and skin or for leukemia, tuberculosis, cerebrovascular diseases, heart diseases and liver cirrhosis. A dose-response relationship was demonstrated between the mortality from lung cancer and the degree of exposure. A very high excess mortality from lung cancer (SMR = 2,500) was seen among copper smelters who were considered to have been most heavily exposed to arsenic or workers who had engaged in sintering and blast furnace operations for 15 years of more before 1949. The latent period of lung cancer was 37.6 years on average, and not related to level of exposure. Twenty-six of 29 deaths from lung cancer among copper smelters occurred after they had left the refinery. Other production workers and clerical workers showed no significant excess mortality from any kind of cancer.
