Summary
Infants with genital anomalies (GA) face high mortality risks, especially those with non-congenital adrenal hyperplasia (CAH) intersex conditions and associated cardiac defects. Screening for cardiac, chromosomal, and dysmorphic syndromes is crucial for affected infants.
Area of Science:
- Pediatric Surgery
- Medical Genetics
- Developmental Biology
Background:
- Genital anomaly (GA) is associated with life-threatening comorbidities that are often underreported.
- Understanding these associated risks is critical for improving patient outcomes.
Purpose of the Study:
- To determine the prevalence and types of associated anomalies in deceased children with genital anomalies.
- To identify risk factors for mortality in infants with GA.
Main Methods:
- Retrospective review of deaths among GA patients over 32 years (1970-2001).
- Exclusion of 70 children with exstrophy/epispadias, focusing on 200 patients with 26 deaths.
- Examination of hospital and postmortem records for demographic data, karyotype, anomalies, and causes of death.
Main Results:
- Congenital adrenal hyperplasia (CAH) patients had low mortality (2/68).
- Non-CAH patients (132) had a 17% mortality rate (24 deaths).
- High mortality in non-CAH intersex GA (16 deaths) and non-intersex GA (8 deaths), including cloacal anomalies, cardiac defects, renal failure (Denys-Drash syndrome), and chromosomal aberrations.
Conclusions:
- Infants with non-CAH intersex GA have a high mortality risk, particularly from cardiac anomalies.
- Non-intersex GA (anorectal malformations, cloacal anomalies) also carries significant mortality due to cardiac and renal issues.
- GA associated with testicular dysgenesis or imperforate anus necessitates screening for cardiac defects, chromosomal anomalies, and dysmorphic syndromes.

01:26Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
01:07Teratogenicity
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...
01:23Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
01:43Sex-linked Disorders
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
