How To Make A Blastocyst., A J Watson, G M Kidder, G A Schultz Oct 1992

How To Make A Blastocyst., A J Watson, G M Kidder, G A Schultz

Obstetrics & Gynaecology Publications

Several of the new reproductive technologies have been cultivated from our current understanding of the genetic programming and cellular processes that are involved in the major morphogenetic events of mammalian preimplantation development. Research directed at characterizing the patterns of gene expression during early development has shown that the embryo is initially under maternal control and later superseded by new transcriptional activity provided by the activation of the embryonic genome. Several embryonic transcripts encoding: (i) growth factors, (ii) cell junctions, (iii) plasma membrane ion transporters, and (iv) cell adhesion molecules have been identified as contributing directly to the progression of the …

Childhood Typhoid Fever Diagnosed In An Urban U.S. Setting., Surinder K. Sodhi, Stephen C. Eppes, Joel D. Klein Oct 1992

Childhood Typhoid Fever Diagnosed In An Urban U.S. Setting., Surinder K. Sodhi, Stephen C. Eppes, Joel D. Klein

Department of Pediatrics Faculty Papers

The majority of cases of childhood typhoid fever diagnosed in the United States occur in persons recently returned from travel abroad. We report two childhood cases of typhoid fever acquired in Mexico and India and diagnosed in an urban United States setting. This report describes these cases and provides insights into the pitfalls in recognizing this condition in a nonendemic setting as well as information concerning differential diagnosis and treatment.

Malignant External Otitis And Mastoiditis Associated With An Igg4 Subclass Deficiency In A Child., Ricardo Castro, Md, Norman Robinson, Md, Joel Klein, Md, William Geimeier, Md Dec 1990

Malignant External Otitis And Mastoiditis Associated With An Igg4 Subclass Deficiency In A Child., Ricardo Castro, Md, Norman Robinson, Md, Joel Klein, Md, William Geimeier, Md

Department of Pediatrics Faculty Papers

We have presented the first child in Delaware with malignant external otitis associated with IgG4 deficiency. Our patient needed three courses of intravenous antibiotics and twice required mastoidectomy, but has recovered completely following the restoration of the natural barrier between the internal and external ear, using a fascial graft from the large temporalis muscle. Some hearing deficit remains.

Susceptibility Of Hepatic Microcirculation To Reperfusion Injury: A Comparison Of Adult And Suckling Rats., Alan M. Yahanda Md, Facs, C N Paidas, M G Clemens Feb 1990

Susceptibility Of Hepatic Microcirculation To Reperfusion Injury: A Comparison Of Adult And Suckling Rats., Alan M. Yahanda Md, Facs, C N Paidas, M G Clemens

Other Specialties

Primary graft failure and vascular thromboses are frequent complications of liver transplantation, yet the mechanisms responsible remain unclear. Previous work from our laboratory has shown that hepatic reperfusion injury results in damage at the microvessel level. The present study was performed to determine whether an increased susceptibility of immature animals to microvascular injury during reperfusion might be a contributing factor in these complications. Suckling (35 to 50 g) or adult (250 to 400 g) rats were subjected to 30 or 60 minutes of hepatic ischemia to the left and median lobes followed by 90 minutes of reperfusion. Control animals were …

Maternal-Neonatal Serum Vitamin A Concentrations., Girish S. Shirali, D G. Oelberg, K P. Mehta Jul 1989

Maternal-Neonatal Serum Vitamin A Concentrations., Girish S. Shirali, D G. Oelberg, K P. Mehta

Manuscripts, Articles, Book Chapters and Other Papers

Prevention of neonatal vitamin A deficiency is related to the adequacy of maternal vitamin A stores. In this study we investigated maternal and cord serum vitamin A and retinol-binding protein (RBP) values in an Indian population including, for the first time, clinically vitamin A-deficient mothers. Twenty-eight maternal-neonatal pairs were selected from maternal cohorts of high socioeconomic status without clinical evidence of vitamin A deficiency (group I) and low socioeconomic status with conjunctival xerosis and Bitot's spots (group II). Maternal education, caloric and vitamin A intakes, weight, height, hemoglobin, and birth weight were significantly lower in group II. Serum vitamin A …

Animal Bite Infections., Joel D. Klein, Md Jan 1989

Animal Bite Infections., Joel D. Klein, Md

Department of Pediatrics Faculty Papers

Animal bites have become alarmingly common and may represent a quiet epidemic. It is estimated that between 1 and 3.5 million animal bites occur annually in the United States. The highest incidence has consistently been in 5-to-14-year-old schoolchildren, who have greater contact with animals, especially house pets, on a daily basis. This article discusses the epidemiology, microbiology, clinical findings and management of animal bites infections.

Genetics And Epidemiology Of Gallbladder Disease In New World Native Peoples, K M Weiss, R E Ferrell, C L Hanis, P N Styne Nov 1984

Genetics And Epidemiology Of Gallbladder Disease In New World Native Peoples, K M Weiss, R E Ferrell, C L Hanis, P N Styne

Faculty, Staff and Student Publications

Native peoples of the New World, including Amerindians and admixed Latin Americans such as Mexican-Americans, are highly susceptible to diseases of the gallbladder. These include cholesterol cholelithiasis (gallstones) and its complications, as well as cancer of the gallbladder. Although there is clearly some necessary dietary or other environmental risk factor involved, the pattern of disease prevalence is geographically associated with the distribution of genes of aboriginal Amerindian origin, and levels of risk generally correspond to the degree of Amerindian admixture. This pattern differs from that generally associated with Westernization, which suggests a gene-environment interaction, and that within an admixed population …

Vaginal Colonization With Staphylococcus Aureus In Healthy Women: A Review Of Four Studies, Mary Guinan, Bruce B. Dan, Richard J. Guidotti, Arthur L. Reingold, George P. Schmid, Elena J.

Four studies assessed the frequency of vaginal Staphylococcus aureus colonization in healthy women and associated risk factors. An association was found between S. aureus vaginal colonization and colonization at the labia minora and the anterior nares. Significant risk factors associated with an increased risk of vaginal S. aureus in at least one study were a history of genital herpes simplex infection, insertion of tampons without an applicator, and the use of Rely (Procter & Gamble) tampons. The use of systemic antibiotics within 2 weeks of the vaginal culture decreased the risk of recovery of S. aureus. The overall frequency …
