ASSOCIATED NON DIAPHRAGMATIC ANOMALIES AMONG CASES WITH CONGENITAL DIAPHRAGMATIC HERNIA
Genetic Counseling (Geneva, Switzerland)
|December 3, 2015
Summary
Congenital diaphragmatic hernia (CDH) is frequently associated with other major anomalies, affecting nearly two-thirds of cases. Thorough investigation and screening for these associated conditions are crucial for affected infants and fetuses.
Area of Science:
- Medical Genetics
- Pediatric Surgery
- Reproductive Medicine
Background:
- Congenital diaphragmatic hernia (CDH) is a serious birth defect.
- CDH often occurs with other congenital anomalies, impacting patient outcomes.
- Understanding the spectrum of associated anomalies is vital for comprehensive care.
Purpose of the Study:
- To determine the prevalence and types of anomalies associated with CDH.
- To identify patterns of malformations in a large, population-based cohort.
- To inform clinical evaluation and management strategies for CDH.
Main Methods:
- Population-based registry of congenital anomalies.
- Analysis of live births, stillbirths, and terminations over 29 years.
- Inclusion of 386,088 pregnancies with known outcomes.
Main Results:
- 139 cases of CDH identified (prevalence 3.60/10,000 births).
- 61.2% of CDH cases had associated major anomalies.
- Common anomalies included cardiovascular (27.5%), urogenital (17.6%), and musculoskeletal (15.0%) system defects; 18.0% had chromosomal abnormalities.
Conclusions:
- A high proportion of CDH cases (nearly two-thirds) are associated with other anomalies.
- Specific patterns of anomalies exist, necessitating comprehensive evaluation.
- Routine screening for associated anomalies in CDH cases is recommended.

01:07Teratogenicity
4.5K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

01:22Esophageal Perforation-I: Introduction
757
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

01:30Neurulation
47.3K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

02:30Genomic Imprinting and Inheritance
38.7K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

01:27Mitral Valve Prolapse I: Introduction
919
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
