At birth, the child presented with asphyxia due to obstructive apnoea. His trachea was, therefore, intubated immediately. [ncbi.nlm.nih.gov]

Conclusion Severe airway obstruction due to congenital anomalies must be excluded in any dysmorphic child presenting with respiratory distress at birth. [doi.org]

• Marfanoid Habitus

  Two frameshift mutations and a donor-splice one caused MSS, while two missense mutations in the DNA binding/dimerisation domain entailed an overgrowth syndrome with some clinical features resembling Sotos syndrome, accompanied by a marfanoid habitus, [ncbi.nlm.nih.gov]

  However, the most striking feature in both patients was a marfanoid habitus, with long and slender morphotype, a very low BMI, long narrow face, and arachnodactyly. [nature.com]

• Respiratory Insufficiency

  These features prompted us to consider NFIX as a candidate gene for Marshall-Smith syndrome (MSS), a severe malformation syndrome characterized by failure to thrive, respiratory insufficiency, accelerated osseous maturation, kyphoscoliosis, osteopenia [ncbi.nlm.nih.gov]

  Marshall-Smith syndrome is characterized by accelerated linear growth and skeletal maturation, typical facial features, psychomotor delay, and respiratory insufficiency. [ctgt.net]

• Failure to Thrive

  It is hoped that the etiology of the syndrome will be discovered as more cases are recognized and reported by pediatricians caring for infants with failure to thrive, advanced bone age, and chronic respiratory symptomatology. [ncbi.nlm.nih.gov]

  Aggressive treatment for failure to thrive has also allowed her to maintain a weight on the 50th centile. [doi.org]

After considering quality-of-life issues for the patient, surgical treatment was offered for facial dysmorphism. This type of effort has not yet been reported in the literature. [ncbi.nlm.nih.gov]

Management and treatment There is no specific treatment for the syndrome. Malnutrition and respiratory infections should be treated symptomatically. Prognosis The prognosis is poor and the disorder is usually fatal within the first years of life. [orpha.net]

Treatment Long hospital care involving treatment for severe respiratory problems is usually necessary for Marshall-Smith syndrome. [medigest.uk]

Aggressive treatment for failure to thrive has also allowed her to maintain a weight on the 50th centile. [doi.org]

Prognosis The prognosis is poor and the disorder is usually fatal within the first years of life. A few cases of prolonged survival have been reported in patients without respiratory complications and are associated with intellectual deficit. [orpha.net]

Although the prognosis has been poor to date, early recognition and aggressive multi-disciplinary therapy may permit further investigation into the cause and appropriate management of this disorder. [ncbi.nlm.nih.gov]

The purpose of this report is to suggest that early diagnosis and aggressive management may improve the ultimate prognosis with respect to the respiratory and feeding difficulties seen in this rare syndrome. [doi.org]

It is hoped that the etiology of the syndrome will be discovered as more cases are recognized and reported by pediatricians caring for infants with failure to thrive, advanced bone age, and chronic respiratory symptomatology. [ncbi.nlm.nih.gov]

Etiology The cause of this disease remains unknown. Diagnostic methods Diagnosis depends on close examination of the clinical findings and X-ray examinations. [orpha.net]
