Patients may present with sepsis or metastatic spread of septic emboli, most commonly occurring in the lung. This presentation may appear as acute respiratory distress syndrome (ARDS). [emedicine.medscape.com]

A disproportionately higher prevalence may be present in Finland, Belgium and in some parts of India. [radiopaedia.org]

We present a case of a patient that had two inducted abortions for Meckel Gruber syndrome. The diagnosis was confirmed pathohystologicaly. She also had two normal term pregnancies. [minervamedica.it]

Herein we describe two cases of MKS presenting as classical triad. [npplweb.com]

Colobomas may be present in one or both eyes and, depending on their size and location, can affect a person's vision. [ncbi.nlm.nih.gov]

• Occipital Encephalocele

  Diagnostic methods Diagnosis may be made on fetal ultrasonography showing occipital encephalocele and dysplastic kidneys. [orpha.net]

  It is characterized by multiple malformations, mainly large multicystic kidneys, occipital encephalocele (which may cause hydrocephalus), hepatic involvement, and polydactyly (mostly postaxial). [semanticscholar.org]

  Ultrasonographic findings of case 1 were (a) occipital encephalocele and (b) polycystic kidney. FIG. 3. In postmortem fetal examination in case 1, (a) occipital encephalocele, (b) bilateral polycystic kidneys, and (c) polydactyly were detected. [liebertpub.com]

  Occipital encephalocele may result in accumulation of excessive cerebrospinal fluid (CSF) in the skull, which causes pressure on the tissues of the brain (hydrocephaly). [rarediseases.org]

Management and treatment No treatment is currently available for Meckel syndrome which has a constantly fatal outcome. [orpha.net]

Standard Therapies Treatment No curative treatment is currently available for Meckel syndrome which has a constantly fatal outcome due to renal failure and lung hypoplasia. Treatment is symptomatic and supportive. [rarediseases.org]

Treatment and prognosis The condition is almost always fatal at birth either because of pulmonary hypoplasia or neonatal renal failure 3,5. Parents can be counseled appropriately that the subsequent risk is 25%. [radiopaedia.org]

ICSI Procedure Ovarian stimulation was performed by hormonal treatment. [journals.plos.org]

It is mainly used when ultrasonography findings are inconclusive or are insufficient to guide treatment choices. Chromosome analysis is essential to exclude trisomy 13, which Meckel-Gruber syndrome mimics. [emedicine.medscape.com]

Treatment and prognosis The condition is almost always fatal at birth either because of pulmonary hypoplasia or neonatal renal failure 3,5. Parents can be counseled appropriately that the subsequent risk is 25%. [radiopaedia.org]

Prognosis MKS is lethal in utero or in the very early neonatal period with pulmonary hypoplasia and kidney failure as the main causes of early demise. * European Reference Network The documents contained in this web site are presented for information [orpha.net]

Prognosis: Meckel syndrome is a lethal disorder. Most infants are stillborn or die hours or days after birth. A few sometimes survive a few months with poor quality of life. [thefetus.net]

PMID: 27094752Free PMC Article Prognosis Dąbkowska S, Kucińska-Chahwan A, Beneturska A, Ilnicka A, Nowakowska B, Panek G, Roszkowski T, Bijok J Prenat Diagn 2020 Apr;40(5):612-617. Epub 2020 Feb 12 doi: 10.1002/pd.5654. [ncbi.nlm.nih.gov]

Because the prognosis is grim, with death occurring in utero or shortly after birth, prenatal diagnosis has led to therapeutic abortion of many affected fetuses. The mortality rate is 100%, with most fetuses surviving only a few days to weeks. [emedicine.medscape.com]

In recent years, the molecular etiology of the diseases in the ciliopathic group has been elucidated owing to the widespread use of next-generation sequencing technology. [liebertpub.com]

Etiology Defective ciliary biology underlies MKS. Mutations in many different cilia-related genes have been associated with this disorder, often in the context of consanguineous unions. [orpha.net]

Pathophysiology Failure of mesodermal induction has been suggested to cause Meckel-Gruber syndrome. The induction cascades of early morphogenesis involve numerous growth factors, homeobox genes, and paired domain genes. [emedicine.medscape.com]
