Sex chromosome abnormalities occur in at least 1 in 400 births and include the well-described 47,XXX, 47,XXY, 47,XYY, and 45,X karyotypes. The addition of more than one extra X or Y chromosome occurs rarely, and little information is available in the medical literature. Individual case reports make up most of this body of knowledge, and all are based on subjects who identified themselves postnatally. Many were ascertained through screenings of institutions and hospitals; thus, there is no unbiased information on the natural history of poly X and Y karyotypes. A direct relationship between the number of additional sex chromosomes and the severity of the phenotype is generally assumed. The purpose of this article is to summarize what is known about these conditions and to present 10 additional cases. The karyotypes include, 48,XXXX, 49,XXXXX, 48,XXYY, 48,XXXY, 49,XXXXY, 49,XXXYY, 48,XYYY, 49,XYYYY, and 49,XXYYY.

Pomaceous and stone fruits can be degraded by a number of pathogenic species including Monilia laxa, M. fructigena and Rhizopus stolonifer.

[...] [Friedrich] Schatz advises all pregnant women, especially primigravidæ, to consult a physician during the last portion of their pregnancy, and ascertain from him the position of the child, and the necessity, if present, of altering it before labor sets in.

Dawson, editor, The American Journal of Obstetrics and Diseases of Women and Children, volume VI, number 4, New York, N.Y.: William Wood & Co., publishers, […]; London: John Churchill’s Sons, […], →OCLC, page 659:

In connection with the case, I should like to remind you of the fact that extra-uterine pregnancy occurs more frequently in multigravidae than in primigravidae. This has an important bearing on the etiology of ectopic gestation.

1906 February 12, George Gellhorn, “The Diagnosis of Tubal Pregnancy before Rupture”, in Albert E. Taussig, A. S. Bleyer, editors, Quarterly Bulletin: Medical Department of Washington University, volume IV, number 3, St. Louis, Mo.: [Medical Department of Washington University] office of publication, 1806 Locust Street, […], published March 1906, →OCLC, page 167:

The overwhelming majority of primigravidas seen at the clinic are in their middle teens. All but two of these primigravidas were pregnant before their eighteenth birthday. Of thirty-eight primigravidas interviewed none had completed high school; and of these, the ones that were married had husbands who were engaged in low-skill, manual, low-paying occupations.

In the second stage [of labour] for a primigravida, Caesarean section is the method of choice; with a multigravida, a vaginal delivery should be attempted.

1978, Lance Townsend, “Caesarean Section: The Types of Operation”, in Obstetrics for Students, 3rd edition, Melbourne, Vic., Sydney, N.S.W.: The Macmillan Company of Australia, →DOI, →ISBN, page 566:

Primigravidas who find themselves pregnant before they are ready may be more amenable to acceptance if social and financial circumstances are deemed adequate. Multiparas, on the other hand, who feel they have more children than they want may not be abl to overcome feelings of rejection.

Fitzpatrick, editors, Annual Review of Nursing Research, volume 2, New York, N.Y.: Springer Publishing Company, →ISBN, →ISSN, →OCLC, part I (Research on Nursing Practice), page 35:

In the primigravida, particularly the heifer and bitch, it is often found that the cause of the dystocia is relatively simple, such as a slight fetomaternal disproportion, and the application of a little assistance is all that is required.
