Insights
Infants with Fryns syndrome and congenital diaphragmatic hernia (CDH) have a grim prognosis, with a high mortality rate. Early recognition of anomalies and genetic counseling are crucial for potential survival.
Area of Science:
- Medical Genetics
- Neonatal Surgery
- Pediatric Cardiology
Background:
- Fryns syndrome is a rare genetic disorder.
- It is associated with multiple congenital anomalies, notably congenital diaphragmatic hernia (CDH).
- The neonatal survival rate for Fryns syndrome with CDH is poor, estimated around 15%.
Purpose of the Study:
- To detail the management and outcomes of infants diagnosed with Fryns syndrome and CDH.
- To analyze the survival rates and associated complications in this patient cohort.
Main Methods:
- Retrospective review of liveborn patients with CDH between 1995 and 2001.
- Data collected from 83 hospitals and entered into the CDH database.
- Focus on patients identified with Fryns syndrome.
Main Results:
- 23 out of 1,833 CDH patients (1.3%) had Fryns syndrome.
- All affected infants required intubation due to early distress.
- Mortality rate was 83% in Fryns syndrome patients, significantly higher than unilateral CDH (33%).
- 43% had other major anomalies; 3 of 4 survivors showed developmental delay.
Conclusions:
- The prognosis for infants with Fryns syndrome and CDH remains extremely poor.
- Early genetic counseling is recommended.
- Identifying lethal anomalies early may aid in determining potential survival and guiding management decisions.
Purpose:
Fryns syndrome is characterized by multiple congenital anomalies including Congenital Diaphragmatic Hernia (CDH), and has a reported poor prognosis with a survival rate during the neonatal period of approximately 15%. This report details the management and outcome of patients with Fryns syndrome and CDH.
Methods:
Records of all liveborn patients with CDH between 1995 and 2001 in 83 hospitals were entered into the CDH database. Those with Fryns syndrome were reviewed retrospectively.
Results:
A total of 1,833 patients were entered in the database, 23 of these had Fryns (1.3%). All patients experienced early distress requiring intubation. Ten patients (43%) were found to have other major anomalies. Seven patients underwent surgical repair at an average age of 7.5 days (range, 6 hours to 14 days). Mortality rate was 83% compared with 33% of patients with unilateral CDH (P =.01). Ten patients died within the first 24 hours. The parents of 6 patients withdrew support. Of the 4 survivors, 3 have marked developmental delay, whereas the fourth has not yet undergone formal assessment.
Conclusions:
The prognosis of infants with Fryns syndrome and congenital diaphragmatic hernia remains grim. Early genetic counseling and recognition of lethal anomalies may assist in determining which patients may survive.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
