We examined two groups of fetuses in which echocardiography had been performed and in which ventricular volume overload eventually led to fetal hydrops. The first group (18 fetuses) had atrioventricular valve regurgitation and almost all of the fetuses had structural heart disease. No fetus in this group survived the neonatal period; only two of the pregnancies in this first group were terminated. A second group of three fetuses had ventricular volume overload from sacrococcygeal teratomas at 21 to 24 weeks' gestation. These fetuses also had nonimmune hydrops (or it developed), but they did not have structural heart disease or atrioventricular valve regurgitation. Combined ventricular output in this group was calculated by Doppler ultrasound to be greater than twice the normal output for fetuses of the expected gestational weight. The proportion of the combined output to the lower body and the placenta was increased with the increase to the teratoma, exceeding the increase to the placenta. In one fetus, serial study demonstrated increasing output and the development of hydrops. Intrauterine surgery was undertaken to control the high output failure. The abnormal variables tended to revert to normal after replacement of blood loss, and the hydrops disappeared. The pregnancy continued until the spontaneous rupture of membranes at 26 weeks' gestation forced delivery by cesarean section. The infant died from severe hyaline membrane disease. These findings suggest that, in some circumstances, fetal hydrops is a late sign of cardiac failure and heralds incipient death.(ABSTRACT TRUNCATED AT 250 WORDS)

Eight cases of nonimmunologic hydrops fetalis (HF) were seen at Cedars-Sinai Medical Center over a 3.5-year period. The etiology of the HF included 2 cases of fetal-maternal hemorrhage and 1 each of sacral teratoma, tachyarrhythmia, diaphragmatic hernia, neuroblastoma, and heart disease. For 1 infant, the cause was never found. These cases involved various diagnostic and therapeutic dilemmas. Only 4 were anticipated ant partum by ultrasound scanning. Two of the 8 fetuses died in utero, whereas 4 others died in the neonatal period. Earlier diagnosis and evaluation are likely to improve these outcomes.

A case is described of a 54 year old woman who had acute pericarditis with large exudative effusion accompanied by severe right and left ventricular failure. The patient was finally diagnosed with carcinoid heart disease from an ovarian carcinoid teratoma. She was treated with octreotide--a somatostatin analogue--followed by radical surgical resection of the neoplasm. At one year follow up only mild carcinoid tricuspid regurgitation remained. Only 16 cases of carcinoid heart disease from an ovarian primary have been described in literature. Moreover clinically manifest acute, nonmetastatic pericarditis and left heart failure are not considered as possible presentations of carcinoid heart disease, whatever the origin. In a recent series a small pericardial effusion was considered an infrequent and unexpected echocardiographic finding in carcinoid heart patients. One case of "carcinoid pericarditis" has previously been described as a consequence of pericardial metastasis. Left sided heart involvement is usually caused by bronchial carcinoids or patency of foramen ovale; both were excluded in the case presented.

Embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) have the ability (i) to duplicate indefinitely while maintaining pluripotency and (ii) to differentiate into cell types of all three embryonic germ layers. These two properties of ESCs and iPSCs make them potentially suitable for tissue engineering and cell replacement therapy for many different diseases, including Parkinson's disease, diabetes and heart disease. However, one critical obstacle in the clinical application of ESCs or iPSCs is the risk of teratoma formation. The emerging field of molecular imaging is allowing researchers to track transplanted ESCs or iPSCs in vivo, enabling early detection of teratomas.

Cardiac diseases currently lead in the number of deaths per year, giving rise an interest in transplanting embryonic and adult stem cells as a means to improve damaged tissue from conditions such as myocardial infarction and coronary artery disease. After testing these cells as a treatment option in both animal and human models, it is believed that these cells improve the damaged tissue primarily through the release of autocrine and paracrine factors. Major concerns such as teratoma formation, immune response, difficulty harvesting cells, and limited cell proliferation and differentiation, hinder the routine use of these cells as a treatment option in the clinic. The advent of stem cell-derived exosomes circumvent those concerns, while still providing the growth factors, miRNA, and additional cell protective factors that aid in repairing and regenerating the damaged tissue. These exosomes have been found to be anti-apoptotic, anti-fibrotic, pro-angiogenic, as well as enhance cardiac differentiation, all of which are key to repairing damaged tissue. As such, stem cell derived exosomes are considered to be a potential new and novel approach in the treatment of various cardiac diseases.

Partial trisomy of the 10q region was originally reported in 1979 [1]. For 25 years, the diagnosis was made microscopically based on large, visible insertions in the region identified by karyotype analysis. Previous case reports have included both unbalanced translocations and large duplications/insertions in the 10q region [2]. Probands with partial trisomy 10q syndrome often have an abnormal phenotype that may include developmental delay [3-5], craniofacial abnormalities [3, 5], talipes (clubfoot) [2], microcephaly [2-4], or congenital heart disease [2-6]. Prenatal diagnoses by karyotype have been made following ultrasound diagnosis of sacrococcygeal teratoma [7], renal pyelectasis [3, 8-10], and other fetal abnormalities [4]. In this case, we report the first prenatal diagnosis of partial trisomy 10q (10q22.3-10q23.2) with a normal karyotype and an abnormal chromosomal microarray analysis (CMA). This is the smallest copy number variant (CNV) (7.5 Mb) in the 10q22.3-10q23.2 regions yet reported.

A poorly feeding neonate presents the clinician with a diagnostic challenge. Feeding difficulties and irritability may be due to sepsis, congenital heart disease, inborn errors of metabolism, non-accidental head trauma, as well as a vast variety of other pathologies. Teratomas are rare pediatric tumors that can occasionally present in the immediate neonatal period and can manifest in the infant's central nervous system (CNS) with non-specific symptoms of poor feeding, lethargy, and somnolence. Operative resection remains the cornerstone of treatment; however, there is no well-defined role for adjuvant chemotherapy or radiation in these treatments. We report a case of a four-week-old female presenting with progressive feeding intolerance secondary to a near holocord thoracic spinal teratoma. Her tumor was surgically resected and she was treated with adjuvant chemotherapy and radiation for 13 months and is now in clinical remission. While rare, intramedullary spinal cord lesions should be considered in the differential diagnosis of infants presenting with poor feeding and hypotonia.
