XCLUDIKG prematurity, most neona,tal deaths occur in babies having a birth weight in excess of eight pounds (3,636 gm.). As the fetal birth weight curve rises above eight pounds (3,636 gm.) both the fetal mortality and maternal morbidity curves also rise. The relationship between maternal and fetal weight curves has never been clearly established; however, it is known that the two curves often fail to coincide, because there are factors which cause elevation of maternal weight without affecting fetal weight, the most common factor being edema. Practically speaking, the maternal weight curve is followed throughout pregnancy to reveal early evidence of toxemia, as manifested by edema. Clinical investigation has proved tha.t maternal weight can usually be controlled by dietary restrictions ; however, these restrictions have no effect upon fetal weight. Realizing that maternal dietary excessesdo not cause fetal obesity, the most reasonable etiologic factor that presents itself is a disturbance in thyroid metabolism. Williams1 states that hypertrophy of the thyroid can be recognized clinically in 65 to 90 per cent of all pregnant women. Before an organ undergoes hypertropby there must first be an increased demand placed upon that organ. In the case of preg-

nancy this increased tlrma11t1 is I)rohably tlue to the l)reseuce of tllc fetus ill utero. If the orya~t is unable to meet, this tlemand by hypertrophy and hyperplasia.

The average amount of thyroxin found in the blood during pregnancy is twenty units to the cubic centimeter, according to these observers. Souled substantiated the findings of Anselrnino and Hoffman and expressed the helirf that the increase in thyroid hormone ix due to au actual physiologic hyprrfunction of the thyroid glaml during pregnancy. Williarurl believes that thyroid defirienc*y results in a defective germ plasm and premature termination of pregnancy; if pregnancy continues, monstrosities result. Rreckenridge” reports abortion, premxturc labor. and fetal death caused b.v thyroid insuf25 cases in wllich there was complete rclif,f following ficiency; his report includes thyroid medication.

With the foregoiq evidence as a fomldatioli, a series of caases was st.arted, based upon the thesis that fetal obesity is tlue to a fetal thyroid deficiencdy ~r~hic~h can be corrected by placing a sufficient saturatioll of thyroid extract ill the fetal blood stream. One hundred and sixteen women have been given thyroid extract orally during four or more months of their pregwncies. Patients recririip less than four months of continuous treatment have Ilot been included in this series. Each patient, received uot less than 3 gr. (0.2 gm.) ~1~1 not more thall 6 gr.

These women were sern at intervals of note less than two weeks at which time routine prenatal pare was’ given; ii1 adtlition, they were carefnlly examined for evide1ic.r of ~ivl-,ertlir-roitlislu. The fact that these signs failed to develop in a single case is significant and fllrther proves clinically that there is a thyroid deficienc2.v during prepaanc*p : if 116 normal, nonpregnant womeu would be give11 from 3 to 6 gr.

Brown”7 made two very comprehensive reports on the administration of thyroid extract during pregnancy ; he was one of the first, workers to discover the extreme variability of potency of the various Uryroid preparations on the market. Da&s selecting a single product of known high potency agrees wrth Brown ; he advises and giving it continuously to all patients throughout pregnancy. He further advises beginning the administration of thyroid extract prior to the pregnancv to avoid xhorCons and fetal maldevelopments. Mussey and Hairtess advise giving a standard

brand of desiccated thyroid in doses of about 4 gr. (0.24 gm.) daily for three or four days and then dropping to a maintenance dose of 1 to 2 gr. (0.065 to 0.12 gm.) daily.

Basal rates were done on the first 56 cases; the average rate of this group at an average t,ime of four mont,hs’ gestation was plus, 2 per cent ; the average rate after three months of treatment was plus 22 per cent. Basal rates mere discontinued when it was discovered that an elevated rate is normal during the latter half of pregnancay. Williamsl states that there is a definite elevation in the basal metabolic rate (luring the latter half of pregnancy, due to the presence of the fetus in utero. It returns to normal about the tenth post-pa&urn day. Sandiford and Wheeler10 found that the state of pregnancy demands increased secretion of thyroid extract because of the presence of an increasing mass of active protoplasmic tissue, consisting largely of the fetal tissues and partly of an increase in maternal structures incident to

The average maternal weight gain durin g entire pregnancy in this group of 116 cases was 18.2 pounds (8.3 kilograms). The average fetal birth weight was 6.8 pounds (3,090 gm.). There was no fetal mortality or prematurity and no maternal mortality. These weights are not spectacular but they are fairly satisfactory since there were no qualitative or quantitative food restrictions. The most gratifying point in this series is the fact, that no baby weighed more than 7 pounds 12 ounces (3,522 am.) and none less’than 5 pounds 11 ounces (2,590 gm.). Because of the small size of these babies and the fact that no more than 6 gr. (0.4 gm.) of nembutal were used for analgesia in a single case, it was necessary to apply forceps in only twelve instances. Eleven of these were applied below the spines and one in the midplane; this was the largest baby in the group and weighed 7 pounds 12 ounces (3,523 gm.) ; the mother had a justominor pelvis with an anteropost,erior diameter of 10 cm. and a biischial diameter of 8 cm. It. has been suggested recently that thyroid deficiency might play some part in the etiology of the toxemias of pregnancy. Patterson, Hunt, and Nicodemns l2 demonstrated both clinically and experimentally that the increased metabolism of pregnancy produces a subclinical hypothyroidism, which is accompanied by hypercholesteremia. When the maternal thyroid cannot produce sufficient thyroxin t,he fetal thyroid is drained; this constant depletion of fetal thyroxin produces a fetal hypothyroidism and hypercholesteremia.
