Review
VACTERL/VATER association is typically defined by the presence of at least three of the following congenital malformations: vertebral defects, anal atresia, cardiac defects, tracheo-esophageal fistula, renal anomalies, and limb abnormalities. In addition to these core component features, patients may also have other congenital anomalies. Although diagnostic criteria vary, the incidence is estimated at approximately 1 in 10,000 to 1 in 40,000 live-born infants. The condition is ascertained clinically by the presence of the above-mentioned malformations; importantly, there should be no clinical or laboratory-based evidence for the presence of one of the many similar conditions, as the differential diagnosis is relatively large. This differential diagnosis includes (but is not limited to) Baller-Gerold syndrome, CHARGE syndrome, Currarino syndrome, deletion 22q11.2 syndrome, Fanconi anemia, Feingold syndrome, Fryns syndrome, MURCS association, oculo-auriculo-vertebral syndrome, Opitz G/BBB syndrome, Pallister-Hall syndrome, Townes-Brocks syndrome, and VACTERL with hydrocephalus. Though there are hints regarding causation, the aetiology has been identified only in a small fraction of patients to date, likely due to factors such as a high degree of clinical and causal heterogeneity, the largely sporadic nature of the disorder, and the presence of many similar conditions. New genetic research methods offer promise that the causes of VACTERL association will be better defined in the relatively near future. Antenatal diagnosis can be challenging, as certain component features can be difficult to ascertain prior to birth. The management of patients with VACTERL/VATER association typically centers around surgical correction of the specific congenital anomalies (typically anal atresia, certain types of cardiac malformations, and/or tracheo-esophageal fistula) in the immediate postnatal period, followed by long-term medical management of sequelae of the congenital malformations. If optimal surgical correction is achievable, the prognosis can be relatively positive, though some patients will continue to be affected by their congenital malformations throughout life. Importantly, patients with VACTERL association do not tend to have neurocognitive impairment.

Polydactyly is a relatively common abnormality in infants. However, it can be a marker of a wide variety of neurological and systemic abnormality. Hence, it is important for pediatrician and physician to have insight into the various association of this apparently innocuous anomaly. In this write-up, we report an extremely rare syndrome associated with polydactyly that is Pallister-Hall syndrome. A 10-month-old male child born by lower segment cesarean section presented with global delay associated with microcephaly, frontal bossing, hypertelorism, flat nose, short philtrum, incomplete cleft in the upper lip and hard palate, polydactyly, and syndactyly. The child presented with repeated vomiting and crying episodes. The patient was investigated which revealed a hypothalamic hamartomas. Pallister-Hall syndrome is a very rare autosomal dominant genetic disorder due to mutation in GLI3 gene in the short arm of chromosome 7 with variable penetrance and expressivity.

Review
A laryngo-tracheo-esophageal cleft (LC) is a congenital malformation characterized by an abnormal, posterior, sagittal communication between the larynx and the pharynx, possibly extending downward between the trachea and the esophagus. The estimated annual incidence of LC is 1/10,000 to 1/20,000 live births, accounting for 0.2% to 1.5% of congenital malformations of the larynx. These incidence rates may however be underestimated due to difficulty in diagnosing minor forms and a high mortality rate in severe forms. A slightly higher incidence has been reported in boys than in girls. No specific geographic distribution has been found. Depending on the severity of the malformation, patients may present with stridor, hoarse cry, swallowing difficulties, aspirations, cough, dyspnea and cyanosis through to early respiratory distress. Five types of laryngo-tracheo-esophageal cleft have been described based on the downward extension of the cleft, which typically correlates with the severity of symptoms: Type 0 laryngo-tracheo-esophageal cleft to Type 4 laryngo-tracheo-esophageal cleft. LC is often associated with other congenital abnormalities/anomalies (16% to 68%), mainly involving the gastro-intestinal tract, which include laryngomalacia, tracheo-bronchial dyskinesia, tracheo-bronchomalacia (mostly in types 3 and 4), and gastro-esophageal reflux disease (GERD). The syndromes most frequently associated with an LC are Opitz/BBB syndrome, Pallister Hall syndrome, VACTERL/VATER association, and CHARGE syndrome. Laryngeal clefts result from failure of fusion of the posterior cricoid lamina and abnormal development of the tracheo-esophageal septum. The causes of the embryological developmental anomalies leading to LC are not known but are thought to be multifactorial. LC appears to be mostly sporadic although some familial cases with suspected autosomal dominant transmission have been reported. The age of diagnosis depends mainly on the severity of the clinical symptoms and therefore on the extent of the LC. Diagnosis is made either based on clinical manifestations or on investigations, such as endoscopy, X-ray, CT scan, performed for other conditions. Differential diagnoses include tracheo-bronchial fistula, gastro-esophageal reflux disease and neurological swallowing disorders, as well as laryngomalacia and laryngeal palsy. Prenatal diagnosis of LC has never been reported, although associated anomalies may be detected on fetal ultrasonography. Once the cleft is diagnosed, it is essential to determine its length to orient the management and treatment approach. Management involves maintenance of satisfactory ventilation, prevention of secondary pulmonary complications as a result of repeated aspirations, and adequate feeding. Endotracheal intubation may be required for respiratory distress in severe cases. Treatment requires endoscopic or external surgery to close the cleft. Surgery should be performed as early as possible to avoid complications related to aspiration and gastric reflux, except in type 0 and type 1 cases in which conservative measures must first be attempted. The prognosis is variable depending on the severity of the LC and associated malformations. Early diagnosis and appropriate treatment and management help to reduce mortality and morbidity.

BACKGROUND
Pallister-Hall syndrome is a rare, autosomal dominant, genetic disorder characterized by different congenital abnormalities: hypothalamic hamartoblastoma, bifid or shortened epiglottis, polydactyly, renal anomalies, and imperforate anus.
CASE PRESENTATION
In this case report, we describe the case of a 13-year-old Lebanese-Armenian boy born with Pallister-Hall syndrome showing newly associated manifestations (orofacial narrowing and tethered cord), and currently showing a spontaneous puberty with normal growth pattern following management with growth hormones.
CONCLUSIONS
This case report shows a practical approach to this very rare syndrome, mainly with testosterone and growth hormones, and its follow-up in the long term. Being familiar with such cases may allow improvement of our knowledge for better management in the future.

Pallister-Hall syndrome (PHS) is an extremely rare syndrome of unknown prevalence with autosomal dominant inheritance due to gene mutations classically characterized by the presence of a hypothalamic hamartoma and polydactyly. Additional diagnostic criteria include bifid epiglottis, imperforate anus, small nails, hypopituitarism, growth hormone deficiency, and genital hypoplasia. It is typically diagnosed in infancy and early childhood, presenting with seizures and/or precocious puberty due to the hypothalamic hamartoma, and with limb anomalies due to central polydactyly. Our patient had presented with polysyndactyly at birth. However, as this is not uncommon in infants and is usually as part of the sporadic, isolated form of polydactyly, no further work up was done. He then presented at age 16 years with a headache and subjective visual changes, with brain imaging revealing a hypothalamic hamartoma. He did not have a history of seizures or central precocious puberty. Genotyping revealed a pathogenic variant affecting the gene. We encourage all clinicians to consider PHS or an associated syndrome with a clinical finding of polydactyly. Further, as the natural history continues to reveal itself, this patient's presentation provides important new data to the broad phenotypic spectrum of PHS.

INTRODUCTION
Pallister-Hall syndrome (PHS) is a rare autosomal dominant syndrome characterized by polydactyly, bifid or shortened epiglottis, visceral anomalies, hypothalamic hamartoma often combined with hypopituitarism. PHS is characterized by significant variability in the expression of clinical symptoms. The clinical course ranges from mild with a good prognosis to severe and which can lead to death during the neonatal period.
CASE REPORT
Two-years-old girl with facial dysmorphia, skeletal malformations of hand and feet and growth hormone deficiency. PHS was diagnosed on the basis of the presented symptoms and genetic tests.
SUMMARY
Skeletal malformations, such as polydactyly or oligodactyly, are a markers which can be associated with endocrinological disorders. Quick and correct diagnosis would help in planning treatment during childhood and giving family counseling, including prenatal advice regarding the next pregnancy of the child's mother.

Pallister-Hall syndrome (PHS) is an extremely rare genetic disorder for which the diagnosis is often overlooked. The objective of this case report is to highlight how clinical features used in conjunction with brain MRI findings can lead to an expeditious diagnosis without the need for invasive measures or genetic test results. We present the case of a three-day-old infant delivered at 34 and 4/7 weeks gestation who presented with mild respiratory distress and bilious emesis in the setting of an uncomplicated gestational course and vaginal delivery with no known teratogen exposure. A diagnosis of Pallister-Hall syndrome was made on the basis of physical exam findings, hormonal abnormalities and the identification of a hypothalamic hamartoma on brain MRI. The patient underwent multiple procedures for diagnosis and management of PHS complications, including a diverting jejunostomy for a long-segment Hirschsprung's and a laryngoscopy which identified a bifid epiglottis. The patient tolerated the interventions and did not have seizures on admission. The MRI brain detection of a hypothalamic hamartoma led to an earlier diagnosis of Pallister-Hall syndrome and thus further screening and identification of complications associated with this disorder were performed before genetic analyses or brain biopsies were obtained. Given the unique MRI features of hypothalamic hamartomas, brain MRI can be a useful tool for making an early PHS diagnosis when taken with clinical features concerning possible PHS.
