LARaLink 2.0: a comprehensive aid to basic and clinical cytogenetic research.

LARaLink 2.0 (Loci Analysis for Rearrangement Link) is an enabling web technology that permits the rapid retrieval of clinical cytogenetic and molecular data. New data mining capabilities have been incorporated into version 2.0, building upon LARaLink 1.0, to extend the utility of the system for applications in both the clinical and basic sciences. These include access to the Chromosomal Variation in Man database and the GEO database. Together these new resources enhance the user's ability to associate genotype with phenotype to identify potential gene candidates. Unlimited access for researchers exploring disease-gene relationships and for clinicians extending practice in patient care is available at LARaLink.bioinformatics.wayne.edu:8080/ unigene.

Acute fatty liver of pregnancy associated with pancreatitis: a life-threatening complication.

OBJECTIVE: Inadequate data describe pancreatitis as a complication in women with acute fatty liver of pregnancy. Our purpose was to report our experience with this complication, which included maternal and perinatal outcomes. STUDY DESIGN: Medical records of patients with acute fatty liver of pregnancy and/or pancreatitis were reviewed over a 15-year period. Records were reviewed for symptoms, laboratory findings, clinical course, and maternal and perinatal outcomes. RESULTS: Persistent nausea and vomiting were the symptoms in 10 of 12 patients (83%). The average maternal age was 26.3 years (range, 21-37 years). There were two maternal deaths (17%); one death occurred despite liver transplantation. Maternal morbidity included encephalopathy (50%), acute respiratory distress syndrome (17%), and renal failure (33%) that resulted from acute tubular necrosis (3 cases) and acute cortical necrosis (1 case) that required renal transplantation. Of the 12 patients, 11 patients (91%) had an elevated serum lipase level, and another patient had an elevated serum amylase level (9%). Eight of 12 patients (67%) underwent radiologic studies, of which 7 patients (88%) were diagnostic for pancreatitis. Radiographic and autopsy findings noted pancreatic inflammation (3 cases), pseudocyst formation (3 cases), and hemorrhagic pancreatitis (1 case). The radiographic and serum laboratory abnormalities occurred after the onset of hepatic and renal abnormalities in all cases. CONCLUSION: Pancreatitis is a potentially lethal complication of acute fatty liver of pregnancy, and all patients with this diagnosis should undergo screening for the abnormality. Pancreatic abnormalities typically appear after hepatic and renal dysfunction.

Vascular occlusion in the management of complicated multifetal pregnancies.

The decision to undergo ST is a personal one for the involved couple, and it can have many psychosocial implications. Appropriate counseling including offering all possible management options with related risks is imperative. Choosing the technique that best serves the clinical situation with minimization of maternal risks should be done taking under consideration the operator's experience. Ultimately, vascular occlusion techniques can help improve multifetal pregnancy outcomes in otherwise challenged gestations.

The frequency and severity of placental findings in women with preeclampsia are gestational age dependent.

OBJECTIVE: The purpose of this study was to evaluate placental lesions found in women with preeclampsia compared with normotensive control subjects and to determine whether the presence of these lesions are related to gestational age at delivery. STUDY DESIGN: Placental disease of women with preeclampsia at 24 to 42 weeks of gestation was compared with the placental disease of normotensive gestational age-matched control subjects. The placental lesions that were studied specifically included decidual arteriolopathy, thrombi in the fetal circulation, central infarction, intervillous thrombi, and hypermaturity of villi. Data analysis involved the chi(2) test, the Student t test, and logistic regression; odds ratios and CIs were estimated. RESULTS: Placentas from women with preeclampsia (n=158) and normotensive control subjects (n=156) were evaluated. Among women with preeclampsia, 67% had severe disease. Placental lesions were studied according to gestational age at delivery: <28, 28 to 32, 33 to 36, and >or=37 weeks of gestation. Of the placental lesions that were studied, decidual arteriolopathy (odds ratio, 23.8, 95% CI 10.0-57.0), hypermaturity of villi (odds ratio, 12.4; 95% CI 5.3-29.2), intervillous thrombi (odds ratio, 1.95;95% CI 1.0-3.7), central infarction (odds ratio, 5.9; 95% CI 3.1-11.1), and thrombi in the fetal circulation (odds ratio, 2.8; 95% CI 1.2-6.6) were found to have significantly higher rates in the preeclamptic group. In contrast, the rate of chorioamnionitis was significantly lower in the preeclamptic group (odds ratio, 0.2; 95% CI 0.1-0.4). The rates of abruptio placentae and meconium staining were not different between the two groups. Within the preeclamptic group, the rates of decidual arteriolopathy (P<.0001), central infarction (P=.0001), and hypermaturity of villi (P<.0001) were higher the earlier the gestational age at delivery. CONCLUSION: Placentas in women with preeclampsia have increased amounts of disease. The rate is increased with lower gestational ages at the time of delivery for women with preeclampsia.

A suite of novel human spermatozoal RNAs.

We recently described a complex population of spermatozoal coding RNAs that are delivered to the oocyte on fertilization. These are derived throughout spermatogenesis, representing a record of past events. Recently, evidence has been provided that micro-RNAs are present in testes, suggesting that they might also be carried in ejaculate spermatozoa. To directly test this hypothesis, a unique microarray system capable of directly identifying antisense RNAs and predicted transcripts was utilized. RNA isolated from the ejaculate spermatozoa of 6 normal fertile men was directly hybridized to sense oligonucleotide arrays containing 10,000 elements. This revealed 68 shared RNAs, some of which are similar to those previously defined as micro-RNAs, whereas others were the antisense of previously in silico-predicted transcripts. The results and implications of this study are described in this communication.
