CASE REPORT Short Statured (84cm/101cm) Short neck but NO WEBBING Caries tooth + Anaemic Fontanelles not yet closed Coarse cry Hypertelorism Deafness Frontal bossing Coarse facial features (Non GROPTOUS looking) GENERAL EXAMINATION

GENERAL EXAMINATION : 

GENERAL EXAMINATION

GENERAL EXAMINATION : 

GENERAL EXAMINATION Kyphoscoliosis Manus varus Knock Knees Pectus carinatum Umbilical hernia

SYSTEMIC EXAMINATION : 

SYSTEMIC EXAMINATION Speech not developed Intelligence less than chronological age Sensory, motor system normal, no cerebellar signs, reflexes normal CNS CVS AI normal position S1,S2heard no murmur RS Trachea midline, NVBS, Creps, wheeze + PA Distended Umblical hernia + Hepatomegaly +

INVESTIGATIONS : 

INVESTIGATIONS Hb% - 7.7g% TC – 17,600 cells/mm3 DC – P 29, L 63, E 08 S.Calcium: 10mg/dl S.Phosphate: 5.5mg/dl S.ALP: 264IU/l Thyroid profile: NORMAL Skeletal survey Cetrimide test - NEGATIVE

SKELETAL SURVEY : 

SKELETAL SURVEY

SKELETAL SURVEY : 

SKELETAL SURVEY

CLINICAL DIAGNOSIS : 

CLINICAL DIAGNOSIS A case of Mucopolysaccharidosis, of Type IV (Morquio’s) Symptomatic treatment Broad Spectrum antibiotics Bronchodilators Iron supplements Referred for orthodontic treatment to Meenakshi Dental College, Maduravoyal. TREATMENT ADMINISTERED:

DISCUSSION : 

DISCUSSION MUCOPOLYSACCHARIDOSES

DISCUSSION : 

DISCUSSION Inborn errors of metabolism Autosomal recessive inheritance Lysosomal enzyme defect MUCOPOLYSACCHARIDOSES Mutation in a gene encoding a lysosomal hydrolase involved in the degradation of one or more GAGs Defective lysosomal hydrolase Accumulation of substrate in various tissues, including liver, spleen, bone, skin & CNS

Slide 18: 

MPS – CLASSIFICATION

DISCUSSION : 

DISCUSSION TYPE IV – MORQUIO’S Instability of the odontoid process Genu valgus Kyphosis Growth retardation – short trunk/neck Waddling gait Corneal clouding Hepatomegaly Cardiac valvular diseases Small teeth with thin enamel – freq. caries SKELETAL EXTRA SKELETAL:

DISCUSSION : 

DISCUSSION Urine testing for Keratan sulphate & Chondroitin sulphate Galactose 6-sulphatase & ß Galactosidase enzyme assays (Serum, WBC, cultured fibroblasts) Tissue biopsy – electrophoretic analysis of GAG DNA tests Prenatal diagnosis – Aminocentesis & Chorionic villous biopsy INVESTIGATIONS

DISCUSSION : 

DISCUSSION Mostly CONSERVATIVE Ventriculoperitoneal shunting – Hydrocephalus Posterior spinal fusion – Instability of odontoid process Corneal transplant – Corneal opacities Valvular surgeries – Valvular diseases Hearing aids – Deafness. MANAGEMENT ENZYME REPLACEMENT using RECOMBINANT ENZYME – Holds a promising future

DISCUSSION : 

DISCUSSION TYPE I : Bad Survive upto 2nd decade of life Arrhythmias is commonest cause of death TYPE IV : Better Survive upto 3rd – 4th decade of life Mostly due to CVS complications PROGNOSIS In conclusion . . .
