Familial glucocorticoid deficiency presenting with hyperpigmentation, gigantism, and motor development delay: a case report.
(BioMed Central,London, 2019) Uyangoda, K.; Kamalanathan, P.; Mettananda, S.
BACKGROUND: Familial glucocorticoid deficiency is a rare autosomal recessive disorder characterized by isolated glucocorticoid deficiency. Most patients are diagnosed following episodes of hypoglycemia or convulsion. We report the case of an infant with familial glucocorticoid deficiency who presented with hyperpigmentation, gigantism, and motor developmental delay without documented hypoglycemia, convulsion, or circulatory collapse. CASE PRESENTATION: A 10-month-old Sri Lankan Sinhalese baby boy born to consanguineous parents presented with generalized hyperpigmentation and overgrowth since birth. He had marginal gross motor developmental delay. His weight, length, and head circumference were above normal range for his age. Investigations revealed low serum cortisol and high adrenocorticotrophic hormone levels with no cortisol response following adrenocorticotropin stimulation. Serum electrolytes and aldosterone levels were normal. A diagnosis of familial glucocorticoid deficiency was made based on isolated glucocorticoid deficiency, hyperpigmentation, and tall stature. CONCLUSIONS: This case report highlights that glucocorticoid deficiency can present without documented hypoglycemia and circulatory collapse and a high degree of suspicion is needed in diagnosis.
Spondylocostal Dysplasia in a 7-year-old Sri Lankan girl causing restrictive lung disease: A case report and review of the literature
(Hindawi Pub. Corp., 2020) Kamalanathan, P.; Fernando, M.; Jayawardena, R.; Upasena, A.; Rajindrajith, S.; Mettananda, S.
ABSTRACT: Spondylocostal dysplasia (SCD) is a rare costovertebral malformation characterised by short-trunk short stature. It is a recessively inherited disorder, and commonly identified disease-causing mutations are in DLL3 gene. The reported prevalence is 1 : 200,000 worldwide, and none was reported from Sri Lanka. We report a 7-year-old Sri Lankan girl with spondylocostal dysplasia presenting with short stature and scoliosis. Disproportionate short stature was noted with short upper segment and small thoracic cavity. Skeletal survey revealed fused vertebra involving T5-T6, T9-T10, and L3-L4. Butterfly vertebrae were noted in T2, T4, T6, and T9. Diagnosis of SCD was made based on classic radiological features including vertebral fusion and rib abnormalities. Spirometry was performed due to small thoracic cavity which showed results compatible with moderate to severe restrictive lung disease. The child did not report respiratory difficulties or recurrent chest infections up to the presentation. She was referred to an orthopaedic team which recommended conservative management with close follow-up. In conclusion, spondylocostal dysplasia should be considered in short-trunk short stature with rib abnormalities in the absence of limb shortening. Appropriate treatment and follow-up for restrictive lung disease would determine the long-term outcome.
Streptococcus bovis - unusual etiology of meningitis in a neonate with Down syndrome: a case report
(BioMed Central, 2018) Mettananda, S.; Kamalanathan, P.; Dhananja Namalie, K.
BACKGROUND: Common etiological agents of neonatal meningitis include group B Streptococcus, Escherichia coli, and Staphylococcus aureus. Here we report a rare pathogen - Streptococcus bovis - causing meningitis in a premature neonate with Down syndrome. CASE PRESENTATION: A 26-day-old Asian male neonate with Down syndrome presented with a history of high-grade fever, poor sucking, poor cry, and reduced activity. On admission, he was febrile and had features of circulatory collapse. A cerebrospinal fluid examination confirmed bacterial meningitis and blood culture isolated the causative organism: group D Streptococcus, which was verified as Streptococcus bovis biotype 2. An echocardiogram did not show evidence of infective endocarditis. CONCLUSIONS: This is probably the first report of neonatal meningitis due to Streptococcus bovis in a child with Down syndrome. Although our patient did not show features of overt immunodeficiency, subtle abnormalities in his immune system would have predisposed him to infection with this unusual organism. This case highlights the need for considering unusual pathogens when managing serious infections in children with Down syndrome.
