n 1963, the National Clearinghouse for Poison Control Centers of the U.S. Public Health Service, reviewed poisoning report forms submitted in a 30-month period, July 1959-December 1961. At the time, some confusion resulted because the data involved all The 'c urrent review, age groups. theref'Ore, cQntains only data on children under fivle years of age. The categories of products were selected because these were the products most frequently ingested by children under five. The clearinghouse employs 80 categories in which all medicines and household products ingested are entered. The ten most frequently named substances involved in each of the ten most frequently involvedcategories are-

Since the 1959-61 survey, kerosene has dropped from 6th plaoe to 22nd place (from 2.2 percent to 1.2 percent of the total ingestions), disinfectants have dropped from 8th to 12th (from 2.1 percent to 1.8 percent), lye and corrosives from 9th to 15th (2.1 percent to 1.5 percent) and laxatives from 10th place to 14th (from 1.9 percent to 1.5 percent). Plants were formerly in 16th place and rose to 6th, hormones from 24th to 8th, tranquilizers from 12th to 9th la nd other analgesics from lIth to 10th. Each year the National Clearinghouse receives an increasing number of ingestion reports. The increase probably is attributable to increased reporting rather than an actual greater number 'Of accident.al ingestions. The number of reports in the 1965 review roughly was equal to the number of reports in the 30-month survey, July 1959-December 1961. The tables in which hospitalization percentages are given are based on those reports on which these data were specifically mentioned. It will beoome apparent that there were many reports which did not indicate this information. However, since this type of information would undoubtedly not be included in telephone inquiries to the

poison control center, it is possible that the percentage of hospitalized cases is ,a ctually lower than indicated. Also, the criteria for hospitalization and ingestion cases vary with each hospital. Cases may have been admitted either because of a hospital policy Dr for a 24-hour observation. The hospitalization rate for the 100 products reviewed was 12.5 peroent. In the top ten categories for children under five years of age, there were 20,256 products identified by trade name. Mentioned more than 100 times in this survey were 27 products accounting for 11,245 case reports or 55.5 percent of all the identified products. The other 44.5 percent covered 1,418. aspirin
Aspirin accounted for 25.8 percent of the 1965 accidental ingestion reports to the National Clearinghouse in children under five . Although there were 64 brand names identified in 6,470 reports, three brands, St. Joseph (50.4 percent), Bayer (37.1 percent) and Bufferin (4.8 percent), accounted for 92.3 percent of all identified aspirin ingestions. The brand name was not specified in 9,858 aspirin ingestions. Vol. NS7, No.1, January 1967

soaps, detergents and cleaners
This variegated class of products, second only to aspirin in its involvement with poisoning accidents among children under five, was named in 4.2 percent of the cases reported to the National Clearinghouse in 1965. It was listed on the reports ,as the agent involved in 2,506 ingestions among which 361 trade names were identified. The ten most frequently ingested in this group contributed 1,227 cases or 46.1 percent of the total cases, including those which had no trade name identification. Ammonia, which led the list in 1959~61, is now in third place; probably because of the difference in the age groups involved in the two studies. Ajax, representing five different products, topped the list with a total of 269 cases reported. In those cases in which hospitalization was known, 11.8 percent of the first ten products were admitted. If ammonia were not considered, the hospitalization for the group would be 5.3 percent. Analysis of the reports of one product in this group indicated that hospitalization was the result of fear from caustic burns based on the advertising of the presence of ammonia. However, many recently advertised products "with ammonia" have a low concentration so that this type of injury is unlikely.

bleaches
The ingestion of bleaches among children under five years of age accounted for 3.6 percent of the total ingestions reported (in 1962 it was 5.3 percent). In 1,898 cases in which the trade names were identified, there were 105 products and the ten most frequently mentioned accounted for 1,683 of these reports. Clorox was involved in 66 percent of the cases in which the trade names were identified but there is some evidence that Clorox may be used as a generic name for bleaches when the exact brand name is not known. Following this was Purex (7.5 percent), Roman (5.6 percent), Action (4.8 peroent). The remaining 101 trade names identified constituted only 16.3 percent of the identified bleaches ingested. In those cases where hospitalization was reported among the first ten bleaches ingested, only 8.8 percent of the children were admitted. This indicates a reduction in hospitalization from the 1959-61 data in which the comparable figure was 14.1 percent. vitamins and minerals

age, 1,010 reports were identified with the first ten preparations listed. These ten products accounted for 57.8 percent of the total identified although there were 210 different tr,a de names The hospitalization rate reported. associated with these products appears to be high (9.5 percent); however, when iron preparations are removed, the percent of hospitalization becomes 1.7 percent. The percentage hospitalization associated with ferrous sulphate (41.1) approaches that of lye and corrosives (43.3 percent) and kerosene (49.0 percent). insecticides
In 1965, insecticides (excluding mothballs which are tabulated separately) were involved in 3.2 percent of all the products ingested by children. In 1959-61 tabulations, the percentage was five percent and has shown a steady decline until this new low. Trade names involved in the 1,785 ingestions in which the product was identified numbered 266. There was a relatively large number of oases (271) in which no specific trade name was mentioned. Because some items such as Raid, Black Flag, Ant Button and Chlordane represent several differen t insecticides, their place on this list is meaningless. plants
One hundred and ninety-six plants were involved in 1,299 ingestions in which the plant was identified. The first ten plants on the list accounted for 42.9 percent of the total. polishes and waxes
The polish and wax category contained 134 trade names among 1,231 identified products. The ten most frequently ingested by children under five contributed 785 cases, 63.8 percent of the total; the other 124 trade named products were distributed among 446 cases. Two products, Old English polish (323 cases) and Pride (164 oases) were the most frequently ingested. This group of substances was associated with a high percentage (33,5) of hospitalization (when such information was given) because the main ingredient in many of the polishes is a petroleum distillate. It should be noted, however, that some polishes have a water base. hormones
One of the new categories in the most frequently ingested list is hormones. The first ten products accounted for 936 reports and 71.7 percent of the entire category and 83.3 percent of the identified hormones. Four of the ten most common items ( continued on next page) Vol. NS7, No.1, January 1967

(continued from page 35)
In 1965, reports received by the clearinghouse identified 1,032 tran· quilizers by brand name and 45 prod· ucts ingested by childr,e n under five, The first four names on the list ac· counted for 47.7 percent and the first ten products accounted for 74.0 percent of the tranquilizer ingestion accidents reported to the clearinghouse. Although 90 percent of reports of ingestion accidents in this category involve children under five, two-thirds are in the older age groups and :are predominently adult suicide attempts.
were thyroid preparations and four were oral contraceptives accounting for 49.0 percent and 47.1 percent, respectively, of all hormone ingestions reported among children under five years of age. It is because of the oral contraceptives that the hormone category has entered the top ten. In 1962, hormones accounted for 1.5 percent of the total ingestion reports received by the clearinghouse and in 1965, 2.1 percent. Only 0.9 percent of the oral contraceptive ingestion cases were hospitalized. A recent analysis of oral contraceptive reports showed that where the symptoms were indicated on the forms, 99 percent of the ingestions had checked "signs and symptomsnone." Another analysis of the thyroid ingestions showed that there were very few serious symptoms indicated even when large amounts were reportedly ingested.

other analgesics and antipyretics
This category of products is new to the list of the top ten since 1959-61. It is somewhat surprising that with the great number of potential candidates, there were only 80 items identified which accounted for 1,165 ingestions in children under five. The ten most frequently mentioned products in this category accounted for 63.3 percent of all the identified ingestions. •
