Insights

Infantile hemangiomas can indicate serious structural anomalies. This review updates understanding of PHACE Syndrome (head/neck) and LUMBAR Syndrome (lower body) in infants.

Area of Science:

  • Pediatric Medicine
  • Genetics
  • Dermatology

Background:

  • Infantile hemangiomas (IH) are common vascular tumors in infants.
  • A subset of infants with IH present with extracutaneous anomalies, forming distinct syndromes.
  • PHACE Syndrome and LUMBAR Syndrome are the most recognized syndromes associated with IH.

Purpose of the Study:

  • To provide an updated review of PHACE and LUMBAR syndromes.
  • To detail the presentation and associated anomalies of these syndromes.
  • To discuss current management strategies for PHACE and LUMBAR syndromes.

Main Methods:

  • Literature review of PHACE and LUMBAR syndromes.
  • Analysis of clinical presentations and diagnostic criteria.
  • Synthesis of management guidelines and treatment outcomes.

Main Results:

  • PHACE Syndrome involves anomalies of the Posterior fossa, Eyes, Heart, great vessels, and Esophagus/Aorta, often with ventral abdominal wall defects.
  • LUMBAR Syndrome involves anomalies of the Lower body, including the Urogenital system, Malformation of the abdominal wall, VACTERL-type anomalies, Anal atresia, and Renal anomalies.
  • Both syndromes exhibit a broader phenotypic spectrum than initially described, with overlapping features in some cases.

Conclusions:

  • Early recognition and diagnosis of PHACE and LUMBAR syndromes are crucial for appropriate management.
  • Multidisciplinary care is essential for addressing the complex anomalies associated with these syndromes.
  • Ongoing research is refining the understanding and treatment of IH-associated syndromes.

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Neurulation01:30

Neurulation

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...

Pleiotropy01:33

Pleiotropy

Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Teratogenicity01:07

Teratogenicity

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...

Aneurysm I: Introduction

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...

Disorders of Hemostasis01:24

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.
