Heterotopic Triplet Pregnancy After Clomiphene Citrate.

Heterotopic pregnancy is an exceedingly rare condition in which an intrauterine and extrauterine pregnancy coexist. Superfetation refers to the coexistence of 2 or more fetuses of different gestational ages as a result of ovulation, fertilization, and implantation during an ongoing pregnancy. We present a case of heterotopic triplet pregnancy with a difference in gestational age by crown rump length of more than 1 week between the twin intrauterine pregnancy and the singleton tubal ectopic.

Loperamide-Induced Torsades de Pointes: A Case Series.

Loperamide is an over-the-counter, inexpensive, antidiarrheal opioid that can produce life-threatening toxicity at high concentrations. CASE REPORT 1: A 28-year-old man with a history of depression and substance abuse disorder (SUD) presented to the emergency department (ED) with shortness of breath and lightheadedness. He ingested large amounts of loperamide daily.

Report of Increasing Overdose Deaths that include Acetyl Fentanyl in Multiple Counties of the Southwestern Region of the Commonwealth of Pennsylvania in 2015-2016.

Acetyl fentanyl is a Schedule I controlled synthetic opioid that is becoming an increasingly detected "designer drug." Routine drug screening procedures in local forensic toxicology laboratories identified a total of 41 overdose deaths associated with acetyl fentanyl within multiple counties of the southwestern region of the state of Pennsylvania. The range, median, mean, and standard deviation of blood acetyl fentanyl concentrations for these 41 cases were 0.

Underrepresentation of heroin involvement in unintentional drug overdose deaths in Allegheny County, PA.

Drugs contributing to overdose deaths are listed on death certificates, but their validity is rarely studied. To assess the accuracy of "morphine" and "codeine" listings on death certificates for unintentional overdose deaths in Allegheny County, PA, investigative and laboratory reports were reviewed. Deaths were reclassified as heroin-related if documentation showed 6-monoacetylmorphine in blood or urine, "stamp bags" or drug paraphernalia at scene, history of heroin use, or track marks.

A rexinoid antagonist increases the hypothalamic-pituitary-thyroid set point in mice and thyrotrope cells.

Retinoid X receptor (RXR) signaling influences thyrotrope function. Synthetic RXR agonists, rexinoids, can cause central hypothyroidism. To test the hypothesis that endogenous rexinoids contribute to the TSH 'set point', TαT1 mouse thyrotrope cells were treated with a rexinoid antagonist, LG101208.

Effects of gender and age at diagnosis on disease progression in long-term survivors of cystic fibrosis.

Rationale: Long-term survivors of cystic fibrosis (CF) (age > 40 yr) are a growing population comprising both patients diagnosed with classic manifestations in childhood, and nonclassic phenotypes typically diagnosed as adults. Little is known concerning disease progression and outcomes in these cohorts.

Objectives: Examine effects of age at diagnosis and gender on disease progression, setting of care, response to treatment, and mortality in long-term survivors of CF.

Determination of quantitative trait loci (QTL) for early maturation in rainbow trout (Oncorhynchus mykiss).

To identify quantitative trait loci (QTL) influencing early maturation (EM) in rainbow trout (Oncorhynchus mykiss), a genome scan was performed using 100 microsatellite loci across 29 linkage groups. Six inter-strain paternal half-sib families using three inter-strain F(1) brothers (approximately 50 progeny in each family) derived from two strains that differ in the propensity for EM were used in the study. Alleles derived from both parental sources were observed to contribute to the expression of EM in the progeny of the brothers.

In vivo and microarray analysis of rexinoid-responsive anaplastic thyroid carcinoma.

Purpose: Anaplastic thyroid carcinoma is rare, yet lethal despite aggressive therapy. Molecular targeting may be beneficial using the rexinoid LGD1069, a retinoid X receptor-selective agonist, as a novel treatment. In this report, we describe the efficacy of LGD1069 in anaplastic thyroid carcinoma in vitro and assess the in vivo treatment effects on a responsive cancer.

The role of environmental factors in the causation of sudden death in infants: two cases of sudden unexpected death in two unrelated infants who were cared for by the same babysitter.

We report two cases of sudden unexpected death in two unrelated African American female infants, 2 months and 4 months old. Both infants were attended to by the same babysitter in the same apartment and died 39 days apart in the same bed and in the same bedroom. The autopsy of the first infant revealed sudden unexplained death in an infant.
