GENE/01(P) THE CHILD SYNDROME: CONGENITAL HEMIDYSPLASIA WITH ICHTHYOSIFORM ERYTHRODERMA AND LIMB DEFECTS Preena Uppal ; Premila Paul; Rohit Arora; SS Uppal; Suruchi Bajaj Department of Paediatrics, Safdarjung Hospital, New Delhi [email protected] Introduction: The term CHILD syndrome is proposed as an acronym for congenital hemidysplasia with ichthyosiform erythroderma and limb defects.It is a rare subtype of epidermal nevus syndromes . CHILD syndrome caused by deficiency of 3beta-hydroxysteroid-delta8, delta7isomerase.The syndrome is characterized by unilateral erythema and scaling, with a distinct demarcation in the middle of the trunk. . In addition, ipsilateral hypoplasia o of the skeleton, as well as defects of the brain and the viscera are found. The ratio of females to males is 19:1. Apparently, the CHILD syndrome is genetically determined. Arguments are presented in favor of the hypothesis that the condition is due to an X-linked dominant gene lethal in hemizygous males. Case report : A 6 year old male child,born of non consanguineous marriage presented with multiple asymmetric deformities. The child had right sided hemihypertrophy . Cranial asymmetry - a larger right lateral ventricle , right sided tonsillar enlargement with axial myopia in the right eye with obvious facial asymmetry was present .Unilateral scaly lesions with distinct midline demarcation were present .Kyphoscoliosis with genu valgum deformity and digital hyperplasia of the opposite side was seen. We report this case as the child presented with hemihyperplasia , and contralateral hyperplasia of the digits . CHILD Syndrome usually has ipsilateral defects .Only very few cases of bilateral involvement have been described so far. GENE/02(O) BETA KETOTHIOLASE DEFICIENCY: A CASE REPORT Sindwani A, Jerath N, Sibal A Apollo Centre for Advanced Pediatrics Indraprastha Apollo Hospital New Delhi [email protected] Beta ketothiolase deficiency is a rare autosomal recessive metabolic disorder of ketone body and Isoleucine metabolism characterised by normal early development and recurrent episodes of ketoacidosis in late infancy. Biochemically it is characterized by severe ketoacidosis, normal glucose, mild to moderate hyperammonemia and characteristic urinary organic acid profile. Long term prognosis is favorable if detected and managed early. This report describes one child with Beta ketothiolase deficiency presenting with an episode of acute gastroenteritis followed by severe ketoacidosis and shock. A Seven month old boy born to nonconsanguineous parents presented with vomiting and loose stools for 72 hrs followed by lethargy and dyspnoea. Past history revealed normal motor and social development and no similar episode. He was treated elsewhere with IV sodabicarbonate and volume replacement, but acidosis worsened and he went into shock and coma requiring ventilatory support and was transferred to our centre. Laboratory investigations revealed blood pH=6.69, HCO3=3.1 mmol/L, Lactate=2.8 mmol/L, glucose=114 mg/dL, ammonia= 298 mmol/L. urinary analysis showed 4+ ketones, nil sugar. Child was kept on mechanical ventilation and inotropic support. As the acidosis was persisting, peritoneal dialysis was started which corrected acidosis in 12 hrs. He was subsequently put on protein and fat restricted diet, Carnitine and Riboflavin supplementation. Urinary amino acid profile was normal. Urinary organic acid analysis showed raised level of 2- methyl 3- hydroxybutyrate, triglyglycine and 2methylacetoacetate suggestive of Beta ketothiolase deficiency. He developed complications of ventilator associated pneumonia requiring ventilatory support and gradual weaning over 3 weeks. He was successfully extubated and was discharged on low protein diet and Carnitine and Riboflavin. He is at present symptom free and being followed up. GENE/03(P) DOWN SYNDROME AND THYROID DYSFUNCTION Ritu Gupta, Ravinder K. Gupta Department of Physiology, Govt. Medical College, Jammu (J&K) [email protected] Objective: To study the clinical spectrum of thyroid dysfunction in Down Syndrome Patients. Design: Prospective Study Settings: Pediatric Clinic Material and Methods: About 30 children who met the phenotypic criteria for establishing the diagnosis of Down syndrome were enrolled for the study. Besides clinical features of Down syndrome, they were looked for all clinical signs of hypothyroidism. Besides maternal age, the age, sex, socio-economic and educational status were recorded. Relevant investigations pertaining to hypothyroidism were performed which included X-ray for assessment of bone age, serum cholesterol, ECG and thyroid profile (Serum T3, T4 & TSH levels). Results: The males had definite preponderance (M:F 1.5 :1). The children ranged from 9 month to 12 years (mean age being 3.4 years). The maternal age at the time of birth of child ranged from 25 to 36 years with majority of children were born to 32-36 years age group. About 33% were first in order, 20% each 2nd and 3rd in order and rest 27% were either 4th or 5th in order. Upslanting palpebral fissure (100%), depressed nasal bridge (96%), prominent epicanthal folds (92%) small open mouth (80%), fissured and protruding tongue (72%), low set ears (72%), clinodactyly (64%), high arched palate (60%), wide gap between first and second toe (54%), flat occiput (54%), single transverse palmar crease (48%) etc. were most common obvious features in these children. Generalised hypotonia (80%), lethargy (60%), dullness (50%), rough and dry skin (40%), constipation (27%), delayed motor milestones (17%) delayed mental milestones (15%), etc. were the other presenting features. Three children gave a history of prolonged neonatal jaundice while one child has undergone surgery immediately after birth for imperforate anus. Wide and persistent open anterior fontanelle was seen in 8 cases. Decreased bone age (radiologically) was seen in about 10 cases. The mean T3, T4 and TSH values were 138 ng/ml, 8.7 micro g /ml and 5.4 mu/L. Twelve children (40%) had increased levels of TSH (twice done from different laboratories) with normal or decreased T3 and T4 levels. Other investigation like serum cholesterol in such cases was raised above normal values in 7 cases. ECG was of low voltage type in 3 such cases. Conclusion: About 40% children had increased levels of TSH revealing hypothyroidism. It seems that hypothyroidism is common in Down Syndrome children. Though it requires larger studies, a trial of thyroid replacement therapy (L. thyroxin) can be tried in such cases which can improve the overall mental and physical growth. GENE/04(O) GLUTARIC ACIDURIA TYPE I-IS IT PREVENTABLE CAUSE OF GLOBAL DEVELOPMENTAL DELAY? Shabu Bhahuleyan, Nutan Kamath, Rathika Shenoy, Kamalakshi Bhat Department of Pediatrics Kasturba Medical College , Mangalore [email protected]; [email protected] Glutaric aciduria type I (GA-I) is an autosomal recessive metabolic disorder of lysine and tryptophan metabolism caused by absence or marked decreased activity of the mitochondrial enzyme glutaryl coenzyme A dehydrogenase. The clinical manifestations of GA-I usually develop during first two years of life. We report a 14 month old male child whose timely diagnosis and and treatment for GA-I helped to avoid irreversible neurological damage asssociated with the disease. CASE REPORT- A 18 month old male child born of a non- consanguineous marriage to a primi mother with uneventful pregnancy and labour presented with developmental delay and progressive increase of head size. In the physical examination there was macrocephaly with head circumference more than 95th centile for age, appropriate weight and length for age and motor delay. In the initial workup, biochemical parameters were normal. CT scan brain showed cerebral atrophy with prominent frontotemporal CSF spaces and batwing appearance of bilateral sylvian fissures suggestive of Glutaric acidemia type I. Arterial blood gas and blood ammonia was normal but blood lactate mildly elevated. Blood and urine done for metabolic screening by Tandem Mass Spectroscopy showed Glutaric aciduria type I with severe carnitine deficiency. Hence the child was put on low protien diet with supplementation of carnitine and riboflavin. Presently the child is 26 months with head circumference at the 90th centile for age and gaining milestones. Hence early diagnosis and treatment avoided the irreversible neurological damage associated with the disease. GENE/05(P) CLINICAL PROFILE OF OCULO-AURICULO-VERTEBRAL SPECTRUM –A CASE SERIES Deepika Harit, Pooja Dewan, Piyush Gupta. 27/63,Street No. 8, Vishwas Nagar, Delhi-110032 [email protected] Introduction: oculo-vertebral spectrum (OAVS) refers to three rare disorders that are believed to be intimately related to one another and which represent the range of severity of the same disorder. These disorders are apparent at birth (congenital). It involves malformations of the eyes, ears and spine. Oculo-auriculo-vertebral disorder (OAVD) represents the mildest form of the disorder, while Goldenhar syndrome presents frequently as the most severe form. Hemifacial microstomia appears to be an intermediate form. We had 7 patients 4 males and 3 females. All had unilateral deformed ear along with ipsilateral LMN VII nerve palsy. Patients’ age varied from 15 days-2 yrs at presentation. Only 2 cases had anotia, rest all had microtia. External ear opening was not present in 3 cases. Right half of the face was involved in 5 cases and in 2 left side was involved. 2 children had absent kidney in the affected half of body. Echocardiography revealed VSD in one patient, TOF in 1 patient and normal study in 4. Dermoid cyst in eyes was present in only one patient, all other had normal eyes. 5 cases had normal spine and only 1 had spina bifida. CT scan of ears done in 2 children and it was normal study. Hearing was found to be normal in all babies. GENE/06(P) CLEIDOCRANIAL DYSPLASIA Kalpana Dixit, Ramakant Dixit, Sidharth Sharma Samarpan Child Clinic & Department of Respiratory Medicine, J L N Medical College, Ajmer [email protected] Introduction: Cleidocranial dysplasia is a rare disorder of autosomal dominant inheritance that causes disturbance in the growth of bones of the cranial vault, the clavicles, the maxilla the nasal and the lachrymal bones and the pelvis. Multiple supernumerary and impacted permanent teeth are also commonly seen. Case report: A four year old female child presented with history of short stature, fracture on minor trauma and delayed mile stones. She had dismorphic features i.e. abnormal facies with low set ear, open anterior fontanelle, frontal bossing, bowing of limbs, flat foot, Harrison sulcus, lordosis, hypotonia and high arched palate etc. His investigations revealed hemoglobin 11.8 gm%, serum creatinine 0.5 mg%, serum calcium 10.1 mg%, serum phosphate 6 mg%, serum sodium 143 meq/l, serum potassium 5 meq/l, and normal liver function tests. Skeletal survey revealed severely hypo plastic clavicles seen only in lateral aspect, barrel shaped chest cage and spina bifida at upper dorsal vertebrae. There were no other bony abnormalities. 24 hour urine calcium was 53.76 mg, phosphorus 139.4 mg and creatinine 98.16 mg% Tissue trans glutaminase antibody, Ig A level was 13.88 EU/ml. His growth hormone level were slightly reduced although thyroid profile was normal Conclusions: Cleidocranial dysplasia is an uncommon disorder, however, its clinical and radiological manifestations are characteristic. Although benign disorder, it carries with it several medicolegal implications in terms of complications. Management must be tailored specifically to the patient needs. GENE/07(O) FAMILIAL CROSSED POLYSYNDACTYLY Pooja Dewan, Nitin Agarwal, Preeti Dewan Departments of Pediatrics, Surgery and Anaesthesia, University College of Medical Sciences And Guru Teg Bahadur Hospital, Delhi [email protected] "Polysyndactyly" describes both webbing and the presence of an extra number of fingers or toes. Polydactyly of the thumb or the great toe, is classified as preaxial polydactyly, while of the little finger, is called postaxial polydactyly. Affection of the three central digits is referred to as central polydactyly. Coexistence of preaxial polydactlyly of the hand and and postaxial polydactyly of the foot or vice versa, in association with presence of syndactyly is called “crossed polysyndactyly”. We observed an extremely rare form of polysyndactyly affecting 7 members over four generations in an Indian family. A term baby girl delivered in our hospital was found to have polysyndactyly of the hands and feet. A detailed history revealed polysyndactyly in the previous three generations, both in males (4) and females (3). In five members, (grandfather, mother, aunt, uncle, female neonate) over three generations, physical examination was possible. In two, (greatgrandfather and his only son) a detailed family history suggested all the clues to the diagnosis. There was no history of consanguineous marriage in the family. Cutaneous syndactyly was seen in the hands and feet of all members. Polydactyly was hexadactyly in all members except one who had septadactyly. The affection was mostly bilateral with both the sides being mirror images of each other. Four of the members underwent corrective surgery for cosmetic reasons. All members were screened for renal anomalies by ultrasound examination, but were found to be normal. All the members had normal facies, normal stature and normal intelligence. The pattern of inheritance appears to be autosomal dominant with complete penetrance and variable expressivity. GENE/08(O) PYRUVATE KINASE DEFICIENCY Rajiv Kumar E - 03, Housing Complex, Batra Hospital, New Delhi – 110062 [email protected] INTRODUCTION: Erythrocyte pyruvate kinase (PK) deficiency is a rare and incurable genetic disorder. It is a rare cause of neonatal hyperbilirubinemia. We report an infant with neonatal hyperbilirubinemia due to PK deficiency. The initial approach involved rapid evaluation, phototherapy and close monitoring of serum bilirubin levels. CASE REPORT: A sick newborn referred to tertiary level NICU of our hospital with history of meconium stained liquor and respiratory distress at 6 hours of life. He was born to a multigravida mother at term, weighing 2.9 Kg, by normal vaginal delivery following an uneventful pregnancy and labor. There was no significant antenatal history. There was past history of intrauterine death. On examination, he was sick, tachypneic and had mild pallor with icterus. The heart rate was 110/minute; respiratory rate was 64/minute with recession. Intrauterine congenital infections, G-6-PD deficiency and pyruvate kinase deficiency were suspected. Laboratory investigations revealed Hb 8.1 gm%, TLC 24,230/cmm with 73% neutrophils, 24% lymphocytes, 2% monocytes and 1% eosinophils, ESR 58 mm, reticulocyte count 45% and platelet count 80,000/cmm. PT and PTT were normal. Malarial thick and thin smears were negative. Total and conjugated serum bilirubin was 14.9 mg% and 4.8 mg% respectively. Liver enzymes were elevated. Serum electrolytes were normal. Serological tests for VDRL, syphilis and HIV were negative. Hepatitis B surface antigen and hepatitis C antibody were negative. CMV IgG and HSV IgG were positive. G-6-PD level was normal. He was evaluated for hemolytic disease of newborn. Direct and indirect Coomb’s test was negative. He developed jaundice and double volume exchange transfusion done on first day of life. Post-exchange laboratory investigations revealed Hb 10.4 gm%, total serum bilirubin 6.4 mg%, conjugated serum bilirubin 2.7 mg% and serum calcium 10 mg%. He was started on intravenous fluids, IV antibiotics; packed cells transfusion and intensive double surface phototherapy were given. He was discharged after 7 days of admission. At the time of discharge, the infant was clinically better and there was mild icterus. Total and conjugated serum bilirubin was 5.8 mg% and 2.1 mg% respectively; Hb 13.6 gm% and reticulocyte count 26%. He was tolerating feeds well. A quantitative pyruvate kinase screening was done at age of 2 months, which was low. The child was diagnosed as a case of PK deficiency. The child is regularly followed-up. The prenatal diagnosis of PK deficiency in the family was made by direct DNA analysis which describes diagnosis of a novel homozygous mutation in PKLR gene that subsequently helped the family in the next pregnancy. GENE/09(P) JEUNE’S SYNDROME OR ASPHYXIATING THORACIC DYSTROPHY Santosh Kondekar, Keya Lahiri, Rajwanti Vasvani, Suresh Patil Department of Pediatrics, Seth G S Medical College and KEM Hospital Mumbai 400012 [email protected] Introduction: Jeuene syndrome is a potentially lethal rare autosomal recessive congenital dwarfism characterized by typical skeletal dysplasia. We report a case of Jeuene syndrome with a family history. Case details: A four month old male child born out of second degree consanguineous wedlock with bad obstetric history was brought by parents with repeated episodes of fever, cough and breathlessness since neonatal age. Patient was fullterm section delivery for nonprogressive labor. He was the only living child out of total four gestations. The first gestation was terminated following diagnosis of skeletal dysplasia on antenatal sonography in second trimester. Second gestation was aborted spontaneously. Third gestation gave birth to a child with skeletal deformities and child expired in first week of life. All gestations were extensively monitored during antenatal period. Patient had achieved social smile and partial rollover. On examination child had tachypnea with abdominal respiration, with chest retractions. His anthropometry was suggestive of failure to thrive with short lower segment dwarfism. He had small bell-shaped thorax with reduced diameters with micromelia of the limb and short digits. On respiratory examination, he had bilateral crepitations. Rest of the systemic examination was normal. Radiology showed bell-shaped small thorax with reduced diameters; short and horizontal ribs. There were short square iliac wings, flat acetabular margin, short phalanges, metacarpals, metatarsals. All this micromelia is consistent with Jeune’s syndrome. Colour Doppler of heart was normal. Renal functions were normal. Child was discharged after 3 days of artificial ventilation and antibiotic course. Discussion: Jeune syndrome like other thoracic dystrophies has a stormy lethal course. Most children die of respiratory or renal failure. Only a few variants may survive. Characteristic chest appearance is crucial in suspecting thoracic dystrophies. GENE/10(P) MEHMO SYNDROME - A RARE X-LINKED DISORDER - A CASE REPORT Uma Raju, Harmeet Singh Arora, Kirandeep Sodhi, Ravi Ramamurthy, Vishal Puri Dept of Pediatrics, Command Hospital, Pune [email protected] 13 months old male child, third product of second degree consanguineous marriage, with normal elder siblings & no family history of obesity, presented with history of excessive weight gain since birth, generalized seizures since 5 months of age & global developmental delay. No significant antenatal, perinatal & neonatal history. Born to non-diabetic mother through caesarian section with the birth weight of 3.70 Kg. No history suggestive of congenital hypothyroidism. On examination blood pressure - 92/58 mm Hg (<90th centile for age) , weight 15.5 kg ( > 97th centile for age), length- 77 cm, head circumference – 42 cm ( <3rd centile for age), mid arm circumference- 17 cm. Other features included generalized obesity, broad forehead with mild frontal bossing, flat occiput, closed anterior fontanelle, chubby cheeks, large ear lobule, high frontal hairline, hypertelorism, strabismus, downward deviation of mouth, thick lips, short neck, acral edema(mild), bilateral talipes equines varus & micropenis. Testes were palpable inside the scrotum. Neurologically, patient had generalized hypotonia, increased generalised bulk, decreased vision in both eyes, bilateral convergent squint, with preserved pupillary reflexes & normal other cranial nerves. Other systemic examination revealed no abnormality. Detailed ophthalmologic evaluation revealed decreased vision in both eyes & bilateral convergent squint with no structural anomaly. Investigations - normal T3/T4/TSH (on 2 occasions), blood sugar(R) – 114mg%, serum cholesterol – 248 mg%, serum electrolytes within normal range, normal USG abdomen & X ray spine. EEG showed features of diffuse encephalopathy. Chromosomal studies( Fluorescent-in-situhybridisation) were negative for any deletions / microdeletions (done to rule out other possible causes of obesity ). Parents refused consent for muscle biopsy. Patient was discharged on oral antiepileptics after satisfactory control of seizures & advised for physiotherapy & regular follow up in OPD. Final diagnosis of rare MEHMO syndrome(Mental retardation, Epileptic seizures, Hypogonadism and hypogenitalism, Microcephaly, Obesity and Hypotonia) was entertained after further ruling out close differential diagnoses including hypothyroidism, Angelman syndrome, Pradder Willi syndrome, Soto’s syndrome, Turner/Noonan’s Syndrome, Beckwith Weidman Syndrome , Smith-Lemli-Opitz syndrome, Fragile X syndrome & Bordet Beidl syndrome. GENE/11(P) OSTEOGENESIS IMPERFECTA TYPE III: CASE REPORT OF THREE SIBLINGS. Karuna Thapar, Naresh Jindal,Alok Kumar Goyal Department Of Paediatrics, Government Medical College & Hospital Amritsar (Punjab) [email protected] Osteogenesis imperfecta (OI), also known as Brittle Bone Disease, is a heritable disorder of connective tissue. Its hallmark feature is bone fragility, with a tendency to fracture from minimal trauma or from the work of bearing weight against gravity. In the more severe forms of the disorder, the bones are deformed as well as fragile.According to Sillence et al, 4 types have been described, out of which Type-II is lethal in infancy, however, Type-III can have a full life span. No information available regarding exact prevalence, however, in U.S., estimated to be 1 / 20000 live births. We are reporting three siblings of this disease due to its rarity. Case report: Three siblings 7 year old female, 10 year old male and 12 year old female were brought to us for progressive bowing of legs and multiple bone fractures. Perinatal history uneventful and development normal till 4 -5 years of age. Father and mother were short statured but didn’t have any fractures. On examination, a wide open anterior fontanelle , flat mid-face , frontal bossing, multiple fractures involving both clavicles, Humerus, femurs, tibias, pectus carinatum of chest wall, exaggerated metaphyseal flaring at wrist with slender diaphysis, scoliosis and slight bluish sclera were seen. Children were short statured and macrocephalic. There was no hearing loss and neurological examination was normal. Radiological examination has shown multiple bone fracture with loss of bone mass, also popcorn appearance at knee joint was seen. They were classified as Type-III OI according to Sillence classification. GENE/12(P) ORAL ALENDRONATE IN OSTEOGENESIS IMPERFECTA : A REPORT OF 2 CASES Karuna Thapar, Naresh Jindal,Ira Dhawan Department Of Paediatrics, Government Medical College & Hospital Amritsar (Punjab) [email protected] Osteogenesis imperfecta (OI) is a heritable disorder characterized by either a reduction in the production of normal type I collagen or the synthesis of abnormal collagen as a result of mutations in the type I collagen genes. There is no effective medical treatment for OIs. Bisphosphonates are synthetic analogues of pyrophosphate that inhibit bone resorption by their action on osteoclasts. Recently, beneficial effects of intravenous pamidronate treatment are reported in OI. Not much data are available regarding oral alendronate treatment alone in children with OI. We report 2 cases of OI responded favourably to oral alendronate. Case report: Three siblings 7 year old female, 10 year old male and 12 year old female were brought to us for progressive bowing of legs and multiple bone fractures. They were classified as Type-III OI according to Sillence classification. 7 year old female was having severe bronchopneumonia and CCF probably due to immobility from a long time and was given intensive care treatment for the same. Other two were treated with oral alendronate at a dose of 5 mg per day. They were administered pills 30 minutes before the breakfast and asked to stay in upright position for an hour after the dose. At the end of the 6 months of treatment, both children have tolerated well with no side effects. No new fracture reported. Both cases were lost from further follow up. Conclusion: The usage of oral bisphosphonates is inexpensive and easy to administer instead of intravenous form in cases of OI. We conclude that oral alendronate treatment should be offered to all children with OI for better quality of life.
