The rate of early intrauterine growth in twin gestation.
With the use of specimens obtained by induced abortion, the relationships between crown-rump length on the one hand and body weight and menstrual age on the other were investigated in 43 twin fetuses with menstrual ages between 8 1/2 and 21 weeks. This study indicates that the body weight of twins in comparison with length is the same as that of singletons, an indication of the fact that they are not growth retarded. On the other hand, the average crown-rump length when compared with menstrual age is somewhat less than that of singleton fetuses. The possible implications of these findings are discussed in the light of prevailing concepts concerning the growth of twins.

Medical-legal aspects of perinatal and surgical infections.
Hospital-acquired infections probably constitute the greatest single health hazard for hospitalized patients in the United States. Ironically, the increased safety of obstetric and surgical procedures effected by the advent of antibiotics has led to relaxation of attention to proper aseptic techniques.

Control of perinatal infection by traditional preventive measures.
A 9-year review of nosocomial infections occurring in the department of obstetrics and gynecology of a major teaching hospital demonstrated the dramatic effect of strict asepsis and isolation on postoperative infection rates. With rigidly enforced preventive measures and without the use of prophylactic antibiotics, the rates of wound infection and endometritis and the relative prevalence of gram-negative aerobic organisms cultured from these infections could be reduced substantially. The role of anerobes in these infections was not established, since adequate techniques for the accurate diagnosis of anaerobic infection were not available at the time of this study. The relative importance of the numerous infection-control measures used is unclear. It is apparent, however, that by implementing all traditional methods of asepsis, virtually all types of nosocomial infection could be controlled, and the increased prevalence of gram-negative infections observed during the past decades could be reversed.
Ectopic pregnancy as an etiologic agent in appendicitis.
The association of ectopic pregnancy and acute appendicitis has seldom been discussed in literature. This report presents 2 patients who had simultaneous right tubal pregnancies and acute periappendicitis. The cases reported here suggest the possibility that an ectopic pregnancy can produce an inflammatory reaction of the appendix. Ectopic pregnancy as an etiological stimulus for acute appendicitis is discussed. The advisability of examining the appendix at the time of surgery for pelvic disease, and performing an appendectomy at the same time, if pathology of the appendix is suspected, is emphasized. The use of elective appendectomy in surgery for ectopic pregnancy is reviewed.
Experimental design for the surgical relocation of the ovary into the vaginal fornix.
After translocation into the vaginal vault while attached to a pedicle consisting of the infundibulo-pelvic ligament, the ovary was found to maintain its function in laboratory primates. In the majority of the baboons the ovulatory pattern returned within a few weeks after the surgical procedure. The only significant complication was a transitory, and self-limited, infection which was evident on inspection and on the biopsy specimens, but caused no clinical symptoms. By comparing the surgical outcome in two primate species, namely Papio Cynocephalus and Macaca Arctoides, it could be deduced that the Homo Sapiens would be a more suitable experimental model than either of the laboratory primates used in this research. Because there are potentially effective methods for reducing the likelihood of postoperative infection in the relocated ovary, the experience gained by this new method suggests the possibility that it could be utilized in the future for the purpose of collecting ova for in vitro fertilization in carefully selected, and otherwise untreatable, cases of female sterility.
Vaginal transposition of the ovary in primates (Papio cynocephalus and Macaca arctoides).
Experimental data indicate that the time and mechanism of ovulation play a significant role in some cases of infertility and in a broad range of reproductive abnormalities. In order to establish a new experimental model for the study of these phenomena in primates, transposition of the ovary from the pelvis into the vaginal fornix was attempted in 2 species of monkeys: (a) Macaca Arctoides and (b) Papio Cynocephalus. Particularly in the latter species, ovarian relocation into the anterior and the posterior vaginal fornices proved feasible. Most ovaries continued functioning in their new location during the 2-5 months of the follow-up, despite macroscopic and microscopic evidence of infection. Post mortem examination of one of the experimental animals several years after the surgical procedure revealed the presence of an intact functioning ovary still in close contact with the vaginal fornix.
