Objective. Uterine re-evacuation samples taken in cases of suspected residua after curettage are occasionally negative for gestational tissue. We aimed at evaluating the occurrence of such postcurettage re-evacuation-negative samples and at exploring factors that may influence their occurrence. Methods. This was a cross-sectional comparative retrospective study of 69 consecutive women who underwent uterine re-evacuation for suspected postcurettage gestational remnants. Pathologic reports of samples drawn during re-evacuations were reviewed to determine whether the extracted tissue contained gestational tissue. The presence of factors that may influence the rate of a positive or negative sample (eg, sonographic findings, gestational age at initial procedure, and presenting symptom) was noted and compared between women with and without histologically verified remnants. Results. Twenty-eight (41%) of the re-evacuation samples were histopathologically positive for gestational remnants. Residual tissue was more commonly found when the initial evacuation was performed at a more advanced gestational age (>15 weeks). Women referred by emergency department attendants had significantly fewer positive samples. Normal expert sonographic examination practically excluded yielding samples. Conversely, no negative samples were preceded by sonographic reports mentioning residua. Conclusions. Most re-evacuation samples taken during a re-evacuation procedure for suspected residua are negative for gestational tissue. Parameters that are likely related to histologically confirmed gestational residual tissue are advanced gestational age at initial evacuation, level of the sonographer's skill, persistent bleeding as the presenting symptom, and a sonographic report specifically mentioning retained gestational tissue. Key words: abortion, recurettage, residua. t is not uncommon to encounter a woman with findings suggestive of remnants of conception within the endometrial cavity after a dilation and evacuation (D&E) procedure for termination of pregnancy or miscarriage. Irregular vaginal bleeding, abdominal cramps, amenorrhea, and fever with or without vaginal discharge are conditions consistent with residual content. Occasionally, such patients are asymptomatic and their condition is detected after incidental sonographic findings of residual tissue on a scan done for various indications.There are no clear-cut guidelines for the treatment of suspected remnants after curettage; hence, women suspected of having postabortion residua are treated according to local protocols, which include sonographic confirmation of the suspicion by an expert sonogra-

Infants born after PROM have higher ANRBC counts at birth than control infants. We suggest that increased fetal erythropoiesis exists in infants who are delivered after PROM. If correct, our interpretation supports the theory that fetal hypoxia and/or ischemia may result from PROM.

Retrognathia (recessed chin) and prognathism (prominent chin) often present as signs of an underlying condition. Accurate clinical definitions are important. Yet their definitions were according to “clinical impression”, or to seldom used X‐ray criteria. We propose a statistical and anthropometric definition of retrognathia and prognathism based upon the ratio between the goniomaxillar length (distance between the gonion at the mandible angle and the subnasale and the goniomandibular length (distance between the mandible angle and the most anterior point of the bony chin). We assumed that an increase in the ratio indicates retrognathia and a decrease reflects prognathism. We conducted a prospective, observational, anthropometric study in 204 consecutive healthy term infants. Measurements took place on the second day of life, using sliding calipers. Mean ± SD of goniomandibular length (5.1 ± 0.3 cm), goniomaxillar length (5.4 ± 0.3 cm), were calculated. All measurements correlated significantly with gestational age, and with infant birthweight. The mean ± SD goniomaxillar length/goniomandibular length ratio was 1.06 ± 0.05. We defined a normal ratio as being within 2 SD of the mean, that is, between 0.96 and and 1.16. This ratio correlated with neither gestational age nor with birthweight. We conclude that the goniomaxillar length/goniomandibular length ratio can be calculated whenever retro ‐ or prognathism is suspected. A ratio outside of the 95% confidence interval should help in making this diagnosis. An increase in this ratio beyond 2 SD above the mean (1.16) could be interpreted as retrognathia and a decrease beyond 2 SD below the mean (0.96) as prognathism.
