We sent 424 retina specialists questionnaires on fluorescein angiography performed on pregnant women; 399 specialists responded. Of these, 309 (77%) had never performed fluorescein angiography on a pregnant woman. Ninety specialists (23%) had performed at least one fluorescein angiogram on a pregnant woman; detailed information was obtained on 105 patients. Authors of previous reports that included fluorescein angiography during pregnancy provided information about an additional 11 patients. Substantiated side effects were nausea or vomiting in seven patients. Anomalies at birth, an undescended testicle and syndactyly, were reported in two children. There was one stillbirth with pathologic findings classic for toxemia, and one fetal death occurred several months after fluorescein angiography. One therapeutic abortion was performed for complications in toxemia. One spontaneous abortion occurred three days after fluorescein angiography in a patient who was four weeks pregnant. Eight children born to toxemic mothers had low birth weights. We conclude that fluorescein angiography does not cause a high rate of birth anomalies or complications during pregnancy.

Six premature infants (birth weights 920-1320 g) developed marked abdominal distension after birth, and contrast enema examination showed a microcolon. Four of the six were born to mothers with toxemia who received magnesium sulfate. Bilious emesis was absent in all six, despite marked distension and failure to pass meconium. None of the patients had aganglionosis or cystic fibrosis; five of six were followed without surgery and recovered spontaneously. The sixth had perforation 8 hr after contrast enema and required bowel diversion; this infant also survived. This appears to be an equivalent form in small premature infants of the "small-left-colon syndrome" seen in term infants. Surgery should be reserved for complications; it is not necessarily indicated by the finding of a microcolon in such patients.

This study reviews liver disease in toxemia of pregnancy based on 102 cases submitted to the Armed Forces Institute of Pathology. The common clinical features were right upper quadrant and epigastric pain, nausea, vomiting, and elevation of the serum transaminases. Jaundice occasionally developed. These occurred in severe preeclampsia or eclampsia and their cause was usually recognized. However, hepatic symptoms and signs did result in inappropriate diagnoses and misdirected therapy. Such confusion occurred when these were the initial problems confronting the clinician in women presenting with advanced toxemia due to poor prenatal care. They were also likely to be misleading when other more classic parameters, such as blood pressure and proteinuria, were only midly abnormal. Central nervous system complications were the common cause of death but liver disease could be partially or wholly responsible. Extensive periportal lesions, hepatic hematomas, spontaneous rupture, and infarction all contributed to hepatic injury and to morbidity. Fibrin deposition, hemorrhage, or both in the periportal areas was characteristic of the histopathology. Scanning electron microscopy validated this spectrum of change. A toxemic vasculopathy related to severe vasospasm in the hepatic arterial circulation may be responsible.

Certain complications of pregnancy, e.g., threatened spontaneous abortion, toxemia, emesis, and anemia, were studied in pregnant women living in industrial areas contaminated by smelters and the petrochemical industry. Exposure to lead or aromatic hydrocarbons was assessed in parallel by the determination of these agents or their metabolites in blood and urine. Comparison of respective exposure levels was made between women with normal pregnancies and those with complications. Significantly higher levels of lead in blood and increased excretion of the metabolic products of organic solvents were found in women with complicated pregnancies compared to those with normal pregnancies. Threatened spontaneous abortion, toxemia, and anemia were associated with higher lead exposure in the vicinity of smelters. In these patients, evidence of disturbances of blood glutathione equilibrium and increased lipid peroxidation were found indicating a decreased ability to compensate for the effects of exposure. Styrene exposure in a petrochemical industrial area was associated mainly with late toxemia and nephropathy. Patients with these complications also had a tendency to elevated exposure to other aromatic hydrocarbons. It is suggested that complications of pregnancy may be induced by environmental agents at levels lower than those that result in pregnancy loss or preterm birth.

As in cases of HELLP-Syndrome both the mother and the fetus are at greater risk we analyzed retrospectively the clinical records of 14 patients concerning changes of typical laboratory parameters, clinical course including time of correct diagnosis, as well as fetal and maternal complications. The death of one woman represents a maternal mortality rate of 7.1% whereas perinatal mortality ranged 20% due to 3 intrauterine fetal losses. In our study group the mean time interval from onset of clinical symptoms like pain, vomiting etc. until admission to our department was 8.2 days (median: 4 days). Incorrect interpretation of abdominal pain as the leading symptom, the absence of signs of toxemia and missing or only moderate changes of the typical laboratory parameters cause this delay in correct diagnosis, which presumably has the major negative impact on the unfavorable obstetrical data in cases of HELLP-Syndrome.

We report a patient undergoing femoral callotasis lengthening using the dynamic axial fixator to correct a post-infective leg length discrepancy of 7.8 cm. Seventeen days after the operation, the patient developed a pin site infection, which was successfully treated by oral antibiotics. On the 34th post-operative day, the infection reoccurred, and was accompanied by generalized malaise, vomiting and pyrexia. Serology identified Staphylococcus aureus enterotoxin. Following removal of the fixator, the child recovered, but only four cm of lengthening was achieved. The pins probably acted as a persistent foreign body, with local inflammation creating favorable ground for bacterial infection. The role of the previous multifocal osteomyelitis unclear, but it could have acted as a continuous source of pathogens. The resulting toxemia was not immediately suspected, and could have resulted in the loss of the patient had the fixator not been removed promptly.

In a population-based case-control study of parous women less than 45 years of age, we evaluated the relations of various pregnancy characteristics to maternal breast cancer risk. Cases (N = 1,239) diagnosed with in situ or invasive breast cancer from 1990 to 1992 in Atlanta, GA, Seattle/Puget Sound, WA, and five counties in central New Jersey, and population controls (N = 1,166) identified by random-digit dialing, were interviewed regarding the details of their pregnancies. We used logistic regression to estimate relative risks (RR) and 95% confidence intervals (CI) and to adjust for breast cancer risk factors. Women who reported nausea or vomiting in their first pregnancy had a slightly lower risk of breast cancer (RR = 0.87; 95% CI = 0.72-1.0). We found no strong or consistent associations for maternal risk related to gestational length, pregnancy weight gain, gestational diabetes, pregnancy hypertension, or gender of the offspring, although we found some evidence for reductions in risk for toxemia (RR = 0.81; 95% CI = 0.61-1.1) and specific sex (RR for female twins vs singletons = 0.48; 95% CI = 0.20-1.3) and timing characteristics of twinning. Overall, these data provide little support for the hypothesis that pregnancy hormone levels are associated with subsequent maternal risk of breast cancer in young women.

Reversible posterior leukoencephalopathy syndrome is an increasingly recognized brain disorder most commonly associated with hypertension, toxemia of pregnancy, or the use of immunosuppressive agents. Its clinical features include headache, decreased alertness, mental abnormalities, such as confusion, diminished spontaneity of speech, changed behavior ranging from drowsiness to stupor, seizures, vomiting, and abnormalities of visual perception like cortical blindness. Magnetic resonance imaging shows edematous lesions primarily involving the posterior supratentorial white matter and corticomedullary junction. We describe a 7-year-old uremic girl who developed neurological symptoms of posterior leukoencephalophaty syndrome during the course of acute poststreptococcal glomerulonephritis. Since the symptoms first appeared 24 h after a hypertensive crisis and the patient was uremic at the time of symptoms, we decided to report this patient to discuss the differential diagnosis of neurological symptoms developing during the course of acute poststreptococcal glomerulonephritis.

Reversible posterior leukoencephalopathy syndrome is a brain disorder characterized by headache, nausea, vomiting, visual disturbance, depressed level of consciousness, convulsions and occasionally focal neurologic deficits. It is commonly associated with malignant hypertension, toxemia of pregnancy or the use of immunosuppressive agents. Early diagnosis and specific treatment is essential. We report a case of reversible posterior leukoencephalopathy in the context of a hypertensive crisis in an habitual cocaine sniffer. Reversible posterior leukoencephalopathy must be suspected in every patient with hypertensive crisis and compatible clinic manifestation. Neuroimaging studies show characteristic features which confirm the diagnosis.

Ever since a gradual but significant reduction in the estrogenic and progestogenic components of oral contraceptives (OCs) was made, there has been a corresponding decrease in adverse effects associated with the pill. The beneficial effects include prevention of pregnancy, reduction in pelvic inflammatory disease, protection against ovarian/endometrial cancer and benign breast tumors and ovarian cysts, reduction in the occurrence of rheumatoid arthritis among OC users, and regulation of the menstrual cycle. The adverse effects include diseases of the circulatory system (myocardial infarction, venous thromboembolism, subarachnoid hemorrhage, hypertension), possible carcinogenicity (breast, cervix, melanoma), pituitary adenomas, liver disorders, glucose metabolix effects (diabetes), vitamin status alteration, delay in return of menstruation and fertility, and a number of minor side effects (nausea, vomiting). Contraindications to OC use include history of malignancy of the breast or genital tract, venous thromboembolism, cerebrovascular accident, undiagnosed abnormal vaginal bleeding, focal migraine, or familial hyperlipidemia. The following situations require medical assessment before OCs are prescribed, and medical supervision if OCs are prescribed: age 40+, smoking and age over 35, mild hypertension or a history of hypertensive disease of pregnancy (toxemia), epilepsy, diabetes mellitus, history of bouts of depression, history of oligomenorrhea or amenorrhea in nulliparous women, and gallbladder disease. Problems could occur with OC use in the following situations: 1) lactation (ideally, OCs should be withheld until the child is weaned but if not possible, OCs should not be given until lactation is established); 2) drug interaction (other contraceptive form should be used when the patient is taking antibiotics or anticonvulsants); 3) tropical diseases (studies are still underway); 4) adolescence (very young girls should use other contraceptive method until regular menstruation is established); 5) postcoital contraception (limited use of steroids in emergency situation); and 6) hormonal pregnancy tests (use of oral steroids for pregnancy testing is not recommended). The 3 main types of OCs currently used are the combined estrogen and progestagen, the progestagen-only OC, and the triphasic OC. The lowest effective dose of a compound should be used, and healthy women may continue to use OCs for many years.
