Hydrotherapy in labor.

Maternal anxiety and pain prolong labor and contribute to fetal distress. Hydrotherapy during labor may promote relaxation and decrease pain without the risks caused by other treatments. In this pilot study the psychophysiological effects of hydrotherapy on maternal anxiety and pain during labor were examined. Using a randomized, pretest-posttest control group design with repeated measures, 18 term parturients were assigned to a control or an experimental group. Experimental subjects were placed in a tub of 37 degrees C water for 1 hr during early labor. The Wilcoxon two-sample test revealed statistically significant effects. At 15 min bathers' anxiety and pain scores were decreased compared to nonbathers. At 60 min bathers' pain scores were decreased compared to nonbathers. After 15 min of immersion, bathers had a significantly greater increase in plasma volume than nonbathers. No significant differences were found in urine catecholamines or maternal-fetal complications. The small sample limits conclusions, but the findings offer preliminary support for the therapeutic effects of bathing in labor for acute, short-term anxiety and pain reduction.

Why we should eliminate the due date: a truth in jest.

We currently use flawed calculations to set a woman's due date based on menstrual periods to determine gestational age. We use the estimated gestational age to make management decisions based on our patients' individual needs. This principle is in contrast to our patients' use of dating to set an estimated date of confinement. This date is seen as a very specific point in time. Patients and their families plan on that date and become distressed when the expected date is not met. Given that many patients are induced electively, that many will have their delivery dates changed, and that many will have delivery dates adjusted for medical reasons, and most importantly given that dating is inaccurate and unreliable, we propose eliminating the due date. We propose giving patients a calculated assigned week of delivery at 32 weeks. An assigned week of delivery allows for individualization of obstetric care based on the needs of our patients, their support systems, and hospital staffing. We believe an assigned week of delivery will improve obstetric practice and patient satisfaction.

Use of misoprostol for cervical ripening.

BACKGROUND: Misoprostol, the prostaglandin E1 analog, is increasingly used for cervical ripening and induction of labor. We evaluated our experience with misoprostol in an open-label setting. METHODS: Patients were selected for cervical ripening based on clinical profile. At 3 cm cervical dilation, misoprostol was discontinued and other means of labor augmentation were used. Over 13 months, 470 inductions of labor occurred, and 455 charts were available; 254 patients (56%) received misoprostol for cervical ripening, and 144 (32%) received dinoprostone (prostaglandin E2). RESULTS: With misoprostol, mean time from beginning of contractions until delivery was 7 hours, 30 minutes; vaginal birth occurred in 85% of cases, and spontaneous labor occurred in 38%. Hyperstimulation occurred in 4 cases (1.6%) and precipitate labor in 7 (3%). All infants were discharged in excellent condition; one had a 5-minute Apgar score <7, and 33 (13%) had meconium, none with aspiration. Twenty-three patients who had had a previous cesarean section received misoprostol and delivered vaginally. CONCLUSION: Misoprostol was found to be a safe and effective agent for cervical ripening as part of labor induction.

Mycobacterium chelonae sepsis associated with long-term use of an intravenous catheter for treatment of hyperemesis gravidarum. A case report.

BACKGROUND: Of the 1-2% of pregnant women who develop hyperemesis, the great majority are managed successfully with antiemetics and, when needed, short courses of parenteral medications. Only rarely will chronic parenteral therapy be necessary. Such therapy may be associated with significant complications. CASE: A 38-year-old woman, gravida 3, para 1, induced abortion 1, with a history of hyperemesis in her first pregnancy, developed recurrent hyperemesis at 9 weeks' gestation. After four admissions and a 5.45-kg weight loss at 12 weeks' gestation, a Groshong catheter was placed in the left subclavian vein. The patient was then managed with home droperidol infusions and intravenous hydration as needed. At 30 weeks' gestation she developed tender, erythematous nodules over her legs and right arm. Culture from a biopsy of the nodules grew Mycobacterium chelonae, as did the catheter tip. M chelonae is a ubiquitous, opportunistic, nontuberculous (atypical) mycobacterium. The patient responded slowly to clarithromycin. At 37 weeks she delivered a healthy, 4,080-g, male infant. Three months postpartum the nodules continued to resolve slowly on clarithromycin. CONCLUSION: When chronic parenteral therapy is required for hyperemesis gravidarum, attention must be given to potential complications. Indwelling catheters should be removed as soon as possible.

Preeclampsia into eclampsia: toward a new paradigm.

OBJECTIVE: This study was undertaken to characterize aspects of the natural history of eclampsia. STUDY DESIGN: A retrospective analysis was performed on the records of patients with eclampsia who were delivered at two tertiary care hospitals. RESULTS: Fifty-three pregnancies complicated by eclampsia were identified. Thirty-seven of the women were nulliparous. The mean age was 22 years (range, 15-38 years). Mean gestational age at the time of seizures was 34.2 weeks' gestation (range, 22-43 weeks' gestation). Twenty-eight women had antepartum seizures (53%); 23 of the 28 had seizures at home. Nineteen women had intrapartum seizures (36%). Eight of these women had seizures while receiving magnesium sulfate, and 7 had therapeutic magnesium levels. Six women had postpartum seizures (11%), 4 >24 hours after delivery. Headache preceded seizures in 34 cases. Visual disturbance preceded seizures in 16 cases. The uric acid level was elevated to >6 mg/dL in 43 women. There were no maternal deaths or permanent morbidities. There were 4 perinatal deaths. Two patients had intrauterine fetal deaths at 28 and 36 weeks' gestation. These mothers had seizures at home. One infant died of complications of prematurity at 22 weeks' gestation and one died of respiratory complications at 26 weeks' gestation. There were 4 cases of abruptio placentae, 1 of which resulted in fetal death. Of the 53 cases of eclampsia, only 9 were potentially preventable. One of these was that of a woman who was being observed at home. The other 8 women were hospitalized and had hypertension and proteinuria. Only 7 women could be considered to have severe preeclampsia before seizure (13%), and 4 of these 7 women were receiving magnesium sulfate. CONCLUSIONS: Eclampsia was not found to be a progression from severe preeclampsia. In 32 of 53 cases (60%) seizures were the first signs of preeclampsia. In this series eclampsia appeared to be more of a subset of preeclampsia. Only 9 cases of eclampsia were potentially preventable with current standards of practice. Our paradigm for this disease, as well as our approach to seizure prophylaxis, should be reevaluated.

Controversies in tocolytic therapy.

In general, tocolytic agents are effective in stopping uterine contractions and in temporarily delaying delivery. The benefit of stopping uterine contractions is dependent on the fetal status and gestational age. The rationale for stopping preterm labor is to improve neonatal outcome. At this time, the best way to improve neonatal outcome would be to assure delivery in a center capable of caring for a preterm infant and prescription of glucocorticoids to decrease the risk of respiratory distress syndrome and other neonatal complications. Intravenous tocolysis for premature labor has found a prominent place in the obstetrician's armamentarium. We recommend the use of magnesium sulfate as first-line therapy. When comparing maternal and fetal risks, side effects, and the safety profile, magnesium sulfate is superior to beta-mimetics; however, there are still significant problems with potential morbidity and mortality for both mother and fetus with any tocolytics. Adjunctive use of indomethacin with magnesium sulfate may be used through 32 weeks for up to 48 hours at a time. Most tocolytics are effective in stopping labor for 48-72 hours. None have been shown to decrease the rate of preterm delivery. Once the uterus is quiescent and intravenous tocolytics are stopped, prolonged use of tocolytics has not been shown to be effective in preventing preterm birth. Tocolytics have significant long-term side effects to the mother's cardiovascular system, carbohydrate metabolism, and the fetal cardiovascular system. Thus, the prolonged use of prophylactic tocolytics after cessation of intravenous medications is not recommended. Tocolytics may be an appropriate therapy during preterm labor vaginal bleeding, ruptured membranes, multiple gestation, or advanced cervical dilatation. In all situations, however, careful guidelines must be observed. These guidelines include: (1) maternal and fetal well-being must be established before tocolytic therapy; (2) causes of preterm labor should be evaluated and treated when possible; (3) the risk/benefit ratio for both the mother and fetus must be re-evaluated on an ongoing basis; (4) when tocolytics are given before pulmonary maturity, then antenatal corticosteroids also should be considered in every case; (5) long-term use of tocolytics is difficult to justify at this time; (6) the safest tocolytic should be used for the shortest amount of time possible. It is doubtful, because of the nature of tocolytics, that newer tocolytics will be developed that will eliminate the problems of preterm delivery. Preterm delivery is an end-stage symptom of a multifactorial disease. Preterm labor is one of the last symptoms in a cascade of biochemical events that lead to preterm delivery. The most appropriate way to end preterm delivery would be to prevent the causes that initiate the cascade that ends in preterm labor. Authors' Note: Literally hundreds of papers have been written in the last 30 years on tocoloysis. For the purposes of space, when studies are summarized in peer-reviewed articles, we have referenced the reviews instead of the individual studies.

Psychobiological markers of stress in pregnancy: 6-sulfatoxymelatonin--a longitudinal study.

Maternal stress, physical and psychological, has been associated with adverse pregnancy outcome. The pineal gland is a physiological transducer that reflects adrenergic input. In a recent pilot study, we found urinary 6-sulfatoxymelatonin, the melatonin metabolite, to be elevated after a women spent a day at work compared to levels after a day off work, a leisure day. To evaluate the value of melatonin as a marker of stress, we evaluate melatonin metabolite levels in 121 women, along with perceived anxiety levels and urinary cortisol. Urinary cortisol and maternal anxiety levels each were significantly higher after a work day compared to a leisure day p = .03 and p = .001, respectively. 6-Sulfatoxymelatonin was not significantly different between work and leisure. Changes in cortisol levels were correlated with changes in melatonin metabolite levels (r = .62, p = .001). There was no correlation between changes in anxiety between work and leisure and changes in 6-sulfastoxymelatonin. We found no correlation with 28 week 6-sulfatoxymelatonin or 28-week cortisol and birth weight or gestational age at delivery. Results of this study suggest that melatonin secretion may not be a valuable marker for stress in pregnancy.

Perinatal outcomes in women with systemic lupus erythematosus.

OBJECTIVE: Pregnancies of women with systemic lupus erythematosus (SLE) were studied to assess the effects interaction of this disease and pregnancy. STUDY DESIGN: Charts of pregnant women with a discharge diagnosis of lupus were reviewed. Inclusion criterion was SLE diagnosed by the criteria of the American College of Rheumatology. All patients were cared for at the University of North Carolina Hospitals, a tertiary level university center. RESULTS: Between January 1988 and June 1995, we participated in the care of 21 women with the diagnosis of SLE. Their obstetric histories included a total of 56 pregnancies spanning 19 years. Obstetric histories were divided into pregnancies occurring before the patient was diagnosed with lupus and those pregnancies occurring after she had been given the diagnosis. The diagnosis of lupus was made during the course of five pregnancies; those five were categorized as occurring after diagnosis. Of the pregnancies that occurred before a woman's diagnosis of SLE, 46% resulted in live births, 36% ended in spontaneous abortion, and 18% ended in an intrauterine fetal demise. Among pregnancies occurring after the diagnosis of SLE, 85% resulted in live birth, 10% in spontaneous abortion, 3.3% in intrauterine fetal demise, and 3.3% in neonatal death. Of all live births, 53% were delivered before 37 weeks' gestation. The most common causes of maternal morbidity were joint involvement (n = 8) and dermatologic disorders (n = 6). Other clinical manifestations of SLE included nephritis (n = 5), hypertension (n = 4), pleuritis (n = 3), and thrombocytopenia (n = 3). One maternal death occurred as a result of pulmonary disease. Four pregnancies were complicated by preeclampsia. Seven patients were hospitalized during their pregnancies for lupus-related complications. CONCLUSIONS: Substantial fetal, neonatal, and maternal risks still exist for pregnant women with lupus.

Penicillin desensitization in the treatment of syphilis during pregnancy.

The objective of this study was to compare patients' hospital course, complications, and charges for oral and intravenous (i.v.) desensitization regimens for the treatment of syphilis in the penicillin-allergic gravida. We performed a retrospective search of medical records at two tertiary-level teaching hospitals and reviewed the hospital course of penicillin-allergic gravidas who underwent penicillin desensitization. Between August 1988 and December 1995, 16 procedures for penicillin desensitization were carried out: 11 oral procedures, and 6 i.v. procedures. There were no significant differences between the patients in the oral and i.v. desensitization groups with respect to demographic characteristics, duration of time in a monitored bed, or length of hospital stay. The oral regimen was less expensive than the i.v. regimen ($144.06 vs. $319.48). In our experience, oral and i.v. regimens provide effective desensitization for the treatment of syphilis in penicillin-allergic gravidas. However, the oral route offers ease of administration and substantial cost savings, making it the preferred method.

Clostridium difficile infection in obstetric and gynecologic patients.

We reviewed hospital records of women on the obstetrics and gynecologic services with a diagnosis of antibiotic-associated diarrhea, pseudomembranous colitis, or Clostridium difficile infection to better characterize the incidence and course of women with C difficile infection. Cases were included if there was identification of C difficile by culture or toxin or endoscopic verification of pseudomembranous colitis. Between January 1985 and June 1995, there were 74,120 admissions to the obstetrics and gynecology services at two tertiary level hospitals. Eighteen women were found to have documented C difficile infection (0.02%)--3 from the obstetric services, 10 from the benign gynecologic services, and 5 from the gynecologic/oncology services. Diarrhea developed from 2 days to 30 days after antibiotics had been given (mean, 10 days). Nine patients had fever, six had nausea and vomiting, and five had abdominal pain. Antimicrobial agents given before infection included cephalexin, cefoxitin, imipenem, ciprofloxacin, trimethoprim/sulfamethoxazole, ampicillin, gentamicin, and clindamycin. All patients were treated successfully with inpatient antimicrobial agents-15 with metronidazole and 3 with vancomycin. There was one possible recurrence.

Trauma and pregnancy.

Trauma and/or accidental injury complicates 6-7% of all pregnancies. The management protocols for trauma in pregnancy are based largely on case reports and small series. The purposes of this study were to: describe the demographics of pregnant trauma patients at a tertiary care center and a large community hospital; identify variables predictive of fetal outcome including an examination of Kleihauer-Betke and nonstress testing; and recommend an evaluation and management protocol after trauma based on empirical data rather than anecdotal reports. Data from pregnancies complicated by trauma from July 1987 through October 1993 were retrospectively reviewed. Statistical analysis included Chi-square and Kruskall-Wallis testing. There were 476 medical records available for review. Of the trauma cases, 54.6% were motor vehicle accidents, 22.3% were domestic abuse and assaults, 21.8% were associated with falls, and 1.3% were secondary to burns, puncture wounds, or animal bites. Mean maternal age was 24 years, 49.9% were Caucasian, and 43% were primigravid. Mean gestational age at occurrence of trauma was 25.9 weeks and mean gestational age of delivery was 37.9 weeks. Domestic abuse occurred most frequently before 18 weeks, falls between 20-30 weeks' gestation, and motor vehicle accidents occurred with equal frequency throughout gestation. Uterine contractions occurred in 39.8% of patients and as often as every 1 to 5 min in 18% of patients. Preterm labor occurred in 11.4%, preterm delivery in 25%, and abruptions in 1.58% of the trauma population. Fetal heart rate monitoring was abnormal in 3% of cases. Twenty-seven perinatal deaths were noted and in 14 pregnancies the deaths were related to trauma. Eight of these perinatal deaths were associated with motor vehicle accidents, four with domestic violence, and two with falls. The only preventable perinatal deaths were a twin pregnancy transferred with nonreassuring fetal heart tones. Early warning symptoms of vaginal bleeding, uterine contractions, and/or abdominal and/or uterine tenderness were not predictive of either preterm delivery or adverse pregnancy outcome, sensitivity 52%, specificity 48%. Abnormal monitoring and positive Kleihauer-Betke tests were also not predictive of adverse pregnancy outcome. However, there were no adverse outcomes directly related to trauma when monitoring was normal and early warning symptoms were absent (negative predictive value 100%). Two hundred eighty-nine Kleihauer-Betke tests were performed and only one affected management. Repetitive monitoring over several days did not uncover any patients whose heart rate tracings evolved from normal to abnormal monitoring. Given our findings that prolonged monitoring was not helpful in management of pregnant trauma patients, we support the recommendation that initial external fetal monitoring be performed for 4 hr, and, if reassuring, the patient may be sent home with precautions. We also recommend an Rh-immunoglobulin work-up for all Rh-negative pregnant trauma patients, but do not recommend Kleihauer-Betke testing for Rh-positive women. Given the frequency with which trauma affects pregnancy and the difficulty encountered with identifying variables predictive of pregnancy outcome, there may be great benefits of incorporating trauma prevention into routine prenatal care.

Maternal and fetal outcomes in hyperemesis gravidarum.

OBJECTIVE: This study sought to evaluate maternal characteristics and pregnancy outcomes among women with hyperemesis gravidarum. METHODS: We performed a retrospective analysis of pregnancy records of obstetric admissions during a 6-year period. Women treated as out-patients for hyperemesis were also identified. Hyperemesis was defined as excessive nausea and vomiting resulting in dehydration, extensive medical therapy, and/or hospital admission. Statistical analysis was by t-test and chi square. RESULTS: We identified 193 women (1.5%) who developed hyperemesis among 13,053 women. Racial status, marital status, age, and gravidity were similar between the hyperemesis patients and the general population. However, there were less women with hyperemesis who were para 3 or greater. Forty-six women (24%) required hospitalization for hyperemesis, mean hospital stay 1.8 days, range 1-10 days. One patient required parenteral nutrition, two had yeast esophagitis, none had HIV infection, psychiatric pathology or thyroid disease. Pregnancy outcomes between hyperemesis patients and the general population were similar for mean birth weight, mean gestational age, deliveries less than 37 weeks, Apgar scores, perinatal mortality or incidence of fetal anomalies. Our incidence of hyperemesis (1.5%) is similar to that of other published reports. CONCLUSION: Women with hyperemesis have similar demographic characteristics to the general obstetric population, and have similar obstetric outcomes.

Aneurysm of the vein of Galen: prenatal diagnosis and perinatal management.

An aneurysm of the vein of Galen is a rare arteriovenous malformation of the central nervous system. Fetal manifestations have included nonimmune hydrops, hydrocephalus, and intracranial hemorrhage. This anomaly may be diagnosed prenatally by several imaging modalities. A cystic cranial mass was identified by ultrasound in a fetus at 30 weeks gestation. Both pulsed-wave Doppler and color-velocity imaging studies suggested aneurysm of the vein of Galen was the most likely diagnosis. The fetus demonstrated no evidence of hydrops on serial ultrasound examinations. A 2430 g female infant was delivered vaginally at 35 weeks gestation. Postnatal management included transarterial embolization of the vessels feeding the aneurysm with craniectomy, an intra-aneurysmal balloon, and vascular microcoils. Hydrocephalus developed and a ventriculo-peritoneal shunt was placed. The infant has grown appropriately in the first year of life. An aneurysm of the vein of Galen may be diagnosed prenatally by real-time ultrasound, pulsed-wave Doppler, color-velocity imaging, or magnetic resonance imaging. The presence of this malformation should prompt close follow-up for the remainder of the pregnancy. Careful obstetric management and early postnatal intervention may lead to a favorable outcome.

Water exercise in pregnancy.

Exercise in the water offers several physiological advantages to the pregnant woman. The hydrostatic force of water pushes extravascular fluid into the vascular spaces, producing an increase in central blood volume that may lead to increased uterine blood flow. This force is proportional to the depth of immersion. The increase in blood volume is proportional to the woman's edema. A marked diuresis and natriuresis accompanies the fluid shifts. The buoyancy of water supports the pregnant women. Water is thermoregulating. Studies of pregnant women exercising in the water have shown less fetal heart rate changes in the water than on land in response to exertion. Pregnant women's heart rates and blood pressures during water exercise are lower than on land exercise, reflecting the immersion-induced increase in circulating blood volume. The physiology of water exercise offers some compensation for the physiological changes of exercise on land that may beneficially affect pregnancy.

Fatal lupus pleuritis presenting in pregnancy. A case report.

BACKGROUND: Lupus, one of the most common autoimmune diseases in pregnancy, may involve multiple organ systems with varying severity. The diagnosis and treatment of the disease may be complicated by the physiologic changes of pregnancy. CASE: A 22-year-old woman presented at 29 weeks' gestation with a 4-week history of dyspnea and mild hypertension. She was found to have large bilateral pleural effusions. Her antinuclear antibody level was 1:640, with a speckled pattern, and her complement levels were low. Her urine had 2+ hemoglobin and 2+ protein with hyaline casts. Over the next three days, respiratory compromise increased despite high-dose steroids. A cesarean delivery was performed for fetal compromise. The infant did well after moderate respiratory distress. The mother developed worsening respiratory distress with adult respiratory distress syndrome, and she could not be weaned from the ventilator. Bilateral chest tubes were placed to control her effusions. Urine output remained poor despite pressors and diuretics. Staphylococcal sepsis occurred on postoperative day 5 and precluded our use of other antiinflammatory agents. Over the next 14 days the mother developed seizures, hypotension and eventual respiratory collapse. Autopsy was notable for lupus nephritis and serositis. CONCLUSION: The diagnosis and management of systemic lupus in pregnancy may be extremely difficult. Serositis and nephritis may lead to maternal compromise despite early diagnosis and treatment.

Fetal ovarian torsion appearing as a solid abdominal mass.

Fetal and neonatal ovarian cysts can be small asymptomatic lucencies or large symptomatic echocomplex masses that can cause intestinal obstruction and peritonitis. Solid masses are the most rare form of ovarian cysts. A fetus, anatomically unremarkable at 16 weeks' development, was found at 35 weeks to have a 5 x 5 cm solid mass. After delivery a laparotomy was performed, and a torsed ovary measuring 8 x 7 cm was removed. The infant did well after the procedure. Over 400 cases of perinatal ovarian cysts have been reported in the literature. Only 1% of these are purely echodense. When a fetal abdominal mass is present, separate from bowels and kidneys, a torsed ovary should be considered in the differential diagnosis. Management of the pregnancy and infant may be guided by the fetus or neonate's symptoms.

Transcranial Doppler findings of cerebral vasospasm in preeclampsia.

The objective of this study was to evaluate the effect of preeclampsia and its severity on maternal mean middle cerebral artery blood flow velocity (mean MCA-CBFV) using transcranial doppler sonography (TCD), as well as the effect of magnesium on mean MCA-CBFV in preeclampsia. This study used a prospective, comparative design. TCD was used to examine maternal mean MCA-CBFV in both healthy subjects (controls) and preeclamptic subjects (cases). The two groups were similar in age, gestational age, and parity. Healthy subjects were categorized into three groups: Group I, 6-14 weeks, n = 10; Group II, 24-40 weeks, n = 27; Group III, postpartum n = 15, 12-36 h. Serial TCD examinations of the middle cerebral artery were completed in 21 preeclamptic subjects at four different points in time: Time I is an initial measurement before delivery; Time 2 is also before delivery but after magnesium had been administered. Time 3 is postpartum while on magnesium (12-24 h), Time 4 is postpartum off magnesium, (24-48 h). Preeclamptic subjects had significantly increased mean MCA-CBFV when compared to healthy subjects: antepartum (mean 78.2 vs. 55.1 cm/sec, P < 0.0005); postpartum (mean 101.3 vs. 69.8 cm/sec, P < 0.0001). Severe preeclamptics had significantly higher mean MCA-CBFV than mild preeclamptics at each point in time: Time 1: P < 0.016; Time 2: P < 0.040; Time 3: P < 0.002; and Time 4: P < 0.028. These data support the theory that cerebral vasospasm of the smaller diameter vessels is a major component of preeclampsia.

Cesarean delivery for fetal malformations.

We reviewed existing data on fetal abnormalities to provide guidelines to determine which conditions have an improved neonatal outcome by cesarean delivery. We used Medline database to search for English language papers on a variety of fetal conditions that could influence the mode of delivery. We reviewed these sources with particular attention to how the mode of delivery influenced neonatal outcome. Conflicting data exist regarding optimal mode of delivery for many fetal conditions. Cesarean delivery may improve neonatal outcome for fetuses with isolated meningomyelocele, hydrocephalus with concomitant macrocephaly, anterior wall defects with extracorporeal liver, sacrococcygeal teratomas, hydrops, and alloimmune thrombocytopenia with low platelet count at term. Hydrocephalus without macrocephaly, anterior wall defects without an extracorporeal liver, ovarian cysts, skeletal dysplasias, fetuses whose mothers have immune thrombocytopenic puer-pura and fetuses with alloimmune thrombocytopenia with acceptable platelet counts may safely be delivered vaginally.

Pharmacologic treatment of psychiatric disease in pregnancy and lactation: fetal and neonatal effects.

OBJECTIVE: To review published data pertaining to safety of psychoactive drugs used to treat psychiatric disorders during pregnancy and lactation. DATA SOURCES: A computerized search of articles published through July 1995 was performed on the MEDLINE data base. Additional sources were identified through cross-referencing. METHODS OF STUDY SELECTION: All identified references were reviewed with particular attention given to study design. DATA EXTRACTION AND SYNTHESIS: Each reference was reviewed to determine the safety of psychoactive agents to treat depression, bipolar disease, schizophrenia, and anxiety during pregnancy and lactation. Prospective or large retrospective studies were given more importance than case reports. CONCLUSION: Psychoactive medications may be used during pregnancy. Because data on safety are largely retrospective, treatment decisions must be weighed carefully.

Decidualized umbilical endometriosis.

A case of umbilical endometriosis is presented to highlight the challenges in its diagnosis. The etiology, clinical findings, histologic evaluation, prognosis and treatment options are discussed. While cyclic symptomatology may lend evidence to the diagnosis of umbilical endometriosis, history and clinical findings are often equivocal. Decidualization of umbilical endometriosis can be initially confused with a malignant process on histologic evaluation. The potential for malignant degeneration appears low. Surgical intervention is the treatment of choice.
