Axenfeld Reigers Syndrome – Implications from Dentist viewpoint
SUMMARY As a lot as 150 phrases summarising the case presentation and closing end result (this shall be freely on the market on-line)
A 4 12 months earlier male affected particular person reported with the criticism of quite a lot of decayed enamel. On oral examination, ankyloglossia and hypodontia affecting deciduous along with eternal enamel dentition had been evident along with quite a lot of carious enamel. The child moreover launched with ocular abnormalities which included microphthalamus, microcornea, bilateral nystagmus, alternating esotropia, corectopia, keratoirides adhesions of the left eye, bilateral cataracts and partial imaginative and prescient loss with every the eyes. Systemic consider revealed a ventricular septal defect. The evaluation of Axenfeld Reigers syndrome (ARS) was made on the premise of these medical findings. This example if untreated ends in lack of imaginative and prescient ensuing from glaucoma. The child was properly timed referred for administration thus stopping full imaginative and prescient loss. ARS has an particularly variable medical expression and dental involvement is extraordinarily penetrant and easily visualized. The dentist performs an vital perform in early evaluation of the state of affairs and in stopping the resultant eternal incapacity.
BACKGROUND Why you suppose this case is significant – why did you write it up?
Axenfeld Reigers syndrome is grouped beneath anterior section dysgenesis which is a spectrum of ocular malformations characterised by irregular enchancment of anterior chamber and iris. The incidence of this sickness is 1 in 200,000 dwell births with equal gender predisposition.1 Cases are most incessantly acknowledged in infancy or childhood resulting from irregular look of the anterior section. In some infants the concerns is perhaps tearing photophobia, and corneal clouding which are the symptoms of infantile glaucoma. Whereas some victims may present with seen loss. Orofacial abnormalities are among the many many alternative vital choices which symbolize this syndrome. 2
We proper right here by present a case of ARS the place dental findings carried out an vital perform in evaluation and early referral thus stopping extra points. This affected particular person had no optimistic family historic previous, implying that ARS can also be seen sporadically.
CASE PRESENTATION Presenting choices, medical/social/family historic previous
A four 12 months earlier male affected particular person reported to the dental division with the chief criticism of quite a lot of decayed enamel. The child was born full time interval from a non-consanguineous marriage. Developmental milestones had been attained often. On additional oral examination the child confirmed Dolicocephaly with microcephaly preauricular tags (Decide 1) and a beak shaped nostril (Decide 2). Intraoral examination revealed that the deciduous lower lateral incisors and canines had been clinically missing bilaterally. Root stumps was observed inside the space of the entire left and correct maxillary and mandibular central incisor along with maxillary left lateral incisor. Dental caries was well-known with respect to 52, 54, 55, 64, 65, 74, 75, 84 and 85. The child moreover launched with ankyloglossia (Decide three).
On fundamental examination the child was afebrile, the height and weight had been common for his age. The child launched with bilateral corneal clouding which was seen since starting. Since earlier 6 months the child moreover had the criticism of decreased imaginative and prescient. There was no contributing family historic previous. On ophthalmic examination the child launched with microphthalamus, microcornea, bilateral nystagmus, alternating esotropia, corectopia, keratoirides adhesions with the left eye, bilateral cataracts and partial imaginative and prescient loss with respect to every the eyes (Decide 4).Completely different systemic findings included ventricular septal defect and a hypo pigmented patch on the becoming scapula. The evaluation of Axenfeld Reigers syndrome was reached based of medical findings.
INVESTIGATIONS If associated
An Orthopantomograph was advised to confirm hypodontia. The Orthopantomograph (Decide 5) revealed that the lower deciduous lateral incisors and canines had been missing. Moreover the eternal tooth buds of lower incisors, canines and first premolars (31, 32, 33, 34, 41, 42, 43, and 44) had been absent. Whereas the maxillary arch confirmed no missing enamel.
DIFFERENTIAL DIAGNOSIS If associated
TREATMENT If associated
Oral prophylaxis, restorations of 52, 54, 55, 64, 65, 74, 75 and 84, extractions of 51, 61, 62, 71 and 81 and frenectomy had been deliberate after buying medical clearance.
OUTCOME AND FOLLOW-UP
DISCUSSION Embrace a extremely non permanent consider of comparable revealed situations
Axenfeld Reigers syndrome is an autosomal dominant genetic state of affairs typically, nevertheless can also be seen sporadically, as on this reported case as there was no optimistic family historic previous. Systemic abnormalities and anterior section dysgenesis are pathognomic to ARS. In 1920 Axenfeld described posterior embryotoxon and adherent iris strands, and congenital iris abnormalities with iris hypoplasia, poly cornea and corectopia with completely different systemic findings like dental, facial anomalies had been described in 1935 by Reiger. The combination of the Axenfeld Anomaly and Reiger syndrome is collectively typically known as Axenfeld Reigers syndrome (OMIM: 180500).three, 4
Dental defects in ARS differ from microdontia, hypodontia to complete anodontia. Missing lateral mandibular incisors are described to be the most common attribute. Maxillary hypoplasia can also be seen inside the ARS victims. 5 The presenting case confirmed hypodontia affecting deciduous along with eternal enamel along with ankyloglossia, which is a unusual and distinctive discovering. Completely different systemic findings embrace ear abnormalities, listening to loss, pituitary and cardiac abnormalities, fast standing, hypospadius and limb defects.
The etiology of ARS is thought to be improper differentiation, migration and or arrested enchancment of neural crest cells inside the anterior chamber of the eye, enamel facial bones, cardiovascular system, and pre umbilical pores and pores and skin. The molecular basis of this syndrome resides with the PITX2 and the PITX3 gene which signify the family of homeobox containing transcription concern genes. PITX2 gene mutations (4q25q26) current variability every between and inside households. 4, 6, 7. The reported phenotypes embrace Reiger and Axenfeld anomaly or combined syndrome. Peter’s anomaly and partial aniridia form the differential evaluation. The dental findings are extraordinarily penetrant; solely about 9% of victims with PITX2 mutations present isolated ocular defects. Plenty of genes have been acknowledged which set off anterior section dysgenesis. The rarity, low incidence, extreme morbidity and potential points identify for a by recording and sustaining an data base. This may current an notion into the pathogenesis so that genetic counselling is necessitated and early and speedy treatment is perhaps on the market for this debilitating state of affairs.
Glaucoma in infancy presents as photophobia, tearing and corneal clouding with corneal enlargement which is the complication of ARS. If acknowledged, at this degree surgical intervention can forestall imaginative and prescient loss. When glaucoma is acknowledged in early maturity, the sickness is already inside the superior stage. The proper state of affairs at this degree is to show the sibling or the offspring of the affected particular person with ARS, so that the sickness is acknowledged at an early stage and lack of imaginative and prescient could also be prevented.eight
