In order to study the complications and therapeutic outcome of twin pregnancies, a retrospective survey was carried out in the University Central Hospital of Oulu. Twin deliveries during 1965-1973 numbered altogether 335, and their relative frequency was 1.7 %. The deliveries took place in the 37.2th gestational week on an average. The mean weights of the infants were 2590 g (A) and 2562 g (B). Perinatal mortality in the total series was 9.3 % (A 9.0 % and B 9.6 %). Pregnancy terminated before the 37th week in 29.2% of the cases. Perinatal mortality in this group was 27.0 %, while the corresponding value in the full-term group was 1.7 %. The perinatal mortality of primigravidas (14.1 %) was about twofold compared with that of the multiparas (7.2 %). Twin pregnancies were complicated by hyperemesis gravidarum, pre-eclampsia, anaemia, pyelonephritis and hepatosis more often than were the single pregnancies. The complications which contributed towards an increase of perinatal mortality included uterine bleeding in early and late pregnancy, hydramnion and superimposed pre-eclampsia. The complications generally associated with twin pregnancies and the increased perinatal mortality involved require that mothers with twin pregnancy, particularly primigravidas, should be subjected to intensified follow-up and treatment.

Acute renal failure is a most challenging clinical problem when it occurs in pregnancy. It requires an understanding of the normal physiology of the kidney in pregnancy and the natural history of different underlying renal diseases when pregnancy occurs. Because patients with chronic renal disease may present with worsening proteinuria, hypertension, and renal function, these disorders must be excluded from those conditions that cause acute deterioration of renal failure in otherwise normal women during pregnancy. As in all patients who develop acute renal failure, prerenal and obstructive causes must be excluded. Particularly important causes of prerenal azotemia in pregnancy include hyperemesis gravidarum and uterine hemorrhage, especially if it is unsuspected as in abruptio placentae. Infectious causes of acute renal failure in the pregnant woman include acute pyelonephritis and septic abortion. The clinical presentation of both these conditions should be apparent, and appropriate diagnosis and treatment can then be promptly instituted. Renal cortical necrosis is another cause of renal failure that occurs more frequently in pregnancy, and it must be differentiated from the many causes of acute tubular necrosis that may be associated with pregnancy. Those conditions that cause renal failure unique to pregnancy must always be considered when renal function deteriorates in the last trimester or the postpartum period. Severe preeclampsia, acute fatty liver of pregnancy, and idiopathic postpartum acute renal failure may all present similar complications, but the approach to each of these clinical disorders must be individualized. By understanding the causes of renal functional deterioration in pregnancy, a logical differential diagnosis can be established, allowing appropriate therapeutic decisions to preserve both maternal and fetal well-being.

Acute kidney injury (AKI) is costly and is associated with increased mortality and morbidity. An understanding of the renal physiologic changes that occur during pregnancy is essential for proper evaluation, diagnosis, and management of AKI. As in the general population, AKI can occur from prerenal, intrinsic, and post-renal causes. Major causes of pre-renal azotemia include hyperemesis gravidarum and uterine hemorrhage in the setting of placental abruption. Intrinsic etiologies include infections from acute pyelonephritis and septic abortion, bilateral cortical necrosis, and acute tubular necrosis. Particular attention should be paid to specific conditions that lead to AKI during the second and third trimesters, such as preeclampsia, HELLP syndrome, acute fatty liver of pregnancy, and TTP-HUS. For each of these disorders, delivery of the fetus is the recommended therapeutic option, with additional therapies indicated for each specific disease entity. An understanding of the various etiologies of AKI in the pregnant patient is key to the appropriate clinical management, prevention of adverse maternal outcomes, and safe delivery of the fetus. In pregnant women with pre-existing kidney disease, the degree of renal dysfunction is the major determining factor of pregnancy outcomes, which may further be complicated by a prior history of hypertension.

Timely management of patients presenting to the ED while in their first trimester of pregnancy can improve outcomes for both the patient and the fetus. Common obstetric problems encountered include vaginal bleeding and miscarriage, ectopic pregnancy and pregnancy of undetermined location, and nausea and vomiting of pregnancy, including hyperemesis gravidarum. Optimal diagnostic approaches and management strategies are covered, including which antiemetics are safe to give in pregnancy. Common nonobstetric problems include asymptomatic bacteriuria, urinary tract infections including pyelonephritis, and acute appendicitis. This article also reviews the various imaging modalities available for pregnant patients and reviews the risks of ionizing radiation as well as various contrast media.
