Congenital hydrocephalus in an Egyptian baby with trisomy 18: a case report
<p>Abstract</p> <p>Introduction</p> <p>Trisomy 18 is the second most common autosomal trisomy after Down syndrome (trisomy 21). A variety of anomalies of the central nervous system are observed in cases of trisomy 18. The association between trisomy 18 and congenital hydrocephalus is very rare.</p> <p>Case presentation</p> <p>A 4-month-old male Egyptian baby boy was referred to Assiut University hospital for evaluation of his large-sized head. The initial clinical examination revealed facial dysmorphism including a prominent wide forehead, wide anterior fontanel, bushy eyebrows, synophrosis, small palpebral fissures, ocular hypertelorism, high arched palate, depressed nasal bridge, low-set ears, micrognathia, bilateral clenched hands with over lapping fingers, rocker-bottom feet and penile hypospadius. A computed tomography scan of the patient's head showed a dilatation of all the ventricular systems of the brain that suggested hydrocephalus. A chromosome analysis of his peripheral blood confirmed a trisomy of chromosome 18 (47, XX+18). The hydrocephalus was treated with a ventriculoperitoneal shunt because of the abnormal increase in his head circumference. He was discharged home on nasogastric feeds at the age of 5 months. Despite the advice of the medical team, his parents did not bring him for further follow up. He died at the age of 7 months due to a sudden cardiorespiratory arrest at home.</p> <p>Conclusion</p> <p>Microcephaly is not mandatory for the diagnosis of trisomy 18 syndrome because some cases of trisomy 18 can be associated with other anomalies of the central nervous system, including hydrocephalus. There is no proven explanation for this association, and the management of hydrocephalus in such a situation is not different from the usual course of management.</p
Epicardial Fat Thickness in Children with Classic Congenital Adrenal Hyperplasia
Objective:Epicardial fat thickness (EFT) is an emerging cardio-metabolic risk factor and has been shown to be related to atherosclerosis. EFT has not been studied in the context of CAH. This study aimed to evaluate EFT in children with CAH and its relation to carotid artery intima-media thickness (CA-IMT) and left ventricular (LV) functions.Methods:Thirty-six children with classical CAH were compared with 36 healthy controls. All patients had confirmed CAH and were receiving steroid substitution therapy. Patients and controls underwent anthropometric evaluation, measurement of fasting lipids, glucose, insulin, homeostasis model assessment for insulin resistance (HOMA-IR). LV functions and EFT were assessed using conventional echocardiography. Duplex ultrasonography was used to measure CA-IMT.Results:Compared to controls, patients had greater EFT (p=0.001), CA-IMT (p=0.01), LV mass index (LVMI) (p=0.001) and prolonged mitral deceleration time (DcT) (p=0.01). CAH patients also had significantly worse HOMA-IR (p=0.001) than controls. Abnormalities were worse in uncontrolled CAH on treatment. Multivariate analysis in CAH subjects showed EFT correlated positively with waist circumference odds ratio (OR) [OR=1.9; 95% confidence interval (CI): 1.07-1.14; p=0.01], 17-hydroxyprogesterone [OR=1.6; 95% CI: 1.33-2.89; p=0.05], testosterone concentration (OR=1.7; 95% CI: 1.55-2.13; p=0.01), LVMI (OR=1.14; 95% Cl: 1.08-1.13; p=0.01), mitral DcT (OR=2.25; 95% CI: 1.15-2.05; p=0.01) and CA-IMT (OR=1.6; 95% CI: 1.15-2.05; p=0.01).Conclusion:EFT is elevated in children with classical CAH, particularly in those with poor control, and is correlated with CA-IMT, LV mass and mitral DcT. Measurement of EFT in CAH children may help to identify those at high risk of developing LV dysfunction and subclinical atherosclerosis
Vitamin D level in preschool children with recurrent wheezy chest, and its relation to the severity of the wheezing episodes
Background: Recurrent wheezy chest is a common complaint in pediatric practice. Vitamin D is a potent immunomodulator in allergic diseases as wheezy chest and asthma. The prevalence of vitamin D deficiency has been increasing in Egypt leading to significant morbidities.Objectives: This study aimed to assess serum 25 hydroxy (OH) Vitamin D level in preschool children with recurrent wheezy chest, and to assess its relation to the recurrence, severity, and level of control of the wheezing episodes.Methods: The study included 100 preschool children (aged 2 to 5 years), of both sexes, recruited from the Emergency department, Allergy and Pulmonology units at Assiut University Children Hospital, Egypt. They should have at least 3 documented episodes of wheeze, cough, and difficulty breathing in the last year with clinical improvement on inhaled short-acting beta 2 agonists. Patients were subjected to questionnaire-based history, clinical examination, and laboratory investigations (complete blood count (CBC) with the absolute eosinophil count, serum total IgE level, and serum 25 hydroxy (OH) Vitamin D level). Pediatric Respiratory Assessment Measure (PRAM score) for assessment of the severity of the wheezing episodes and Global Initiative for Asthma (GINA) based level of asthma control for children 5 years and younger were applied. The patients were grouped according to PRAM score to mild, moderate and severe episodes and according to vitamin D level as sufficient and below-sufficient groups (including deficient and insufficient patients).Results: 25(OH) Vitamin D level was below-sufficient in 53% of the studied patients (deficient in 32% and insufficient in 21%). PRAM score was significantly lower in patients with sufficient 25(OH) Vitamin D level versus those with below-sufficient level (p < 0.025). There was a significant negative correlation between PRAM score and 25 (OH) Vitamin D level (r = -0.334, p = 0.001).Conclusion: There is an inverse relationship between 25(OH)vitamin D level and parameters of asthma severity, as well as with the level of asthma control in preschool children with recurrent wheezy chest.Keywords: Vitamin D, recurrent wheezy chest, preschool childre
Hypoparathyroidism in an Egyptian child with Hutchinson-Gilford progeria syndrome: a case report
<p>Abstract</p> <p>Introduction</p> <p>Hutchinson-Gilford progeria syndrome is a rare genetic disorder. It is reported to be present in one in eight million and is characterized by severe growth failure, early loss of hair, lipodystrophy, scleroderma, decreased joint mobility, osteolysis, early atherosclerosis and facial features that resemble those of an aged person. Apart from diabetes mellitus, there are no reported abnormalities of thyroid, parathyroid, pituitary or adrenal function. Here, we report the case of a 10-year-old Egyptian child with Hutchinson-Gilford progeria syndrome and hypoparathyroidism.</p> <p>Case presentation</p> <p>A 10-year-old Egyptian boy was referred to our institution for an evaluation of recurrent attacks of muscle cramps, paresthesia of his fingertips and perioral numbness of two months duration. On examination, we found dilated veins present over his scalp with alopecia and frontal bossing, a beaked nose, thin lips, protruding ears, a high pitched voice with sparse hair over his eyebrows and eyelashes and micrognathia but normal dentition. His eyes appeared prominent and our patient appeared to have poor sexual development. A provisional diagnosis of progeria was made, which was confirmed by molecular genetics study. Chvostek's and Trousseau's signs were positive. He had low total calcium (5.4 mg/dL), low ionized calcium (2.3 mg/dL), raised serum phosphate (7.2 mg/dL), raised alkaline phosphatase (118 U/L) and low intact parathyroid hormone (1.2 pg/mL) levels. He was started on oral calcium salt and vitamin D; his symptoms improved with the treatment and his serum calcium, urinary calcium and alkaline phosphates level were monitored every three months to ensure adequacy of therapy and to avoid hypercalcemia.</p> <p>Conclusion</p> <p>Routine checking of serum calcium, phosphorus and parathyroid hormone will help in the early detection of hypoparathyrodism among children with progeria.</p
Holoprosencephaly in an Egyptian baby with ectrodactyly-ectodermal dysplasia-cleft syndrome: a case report
Hepatitis C virus infection in a child with autoimmune polyendocrine syndrome type 2: a case report
Abstract Introduction Autoimmune polyendocrine syndrome type 2 is a rare disorder. Its prevalence in western populations has been reported as 1.5 to 4.5/100,000. On the other hand, its prevalence in Egypt is unknown. It is characterized by the association of autoimmune Addison’s disease with thyroid autoimmune diseases and/or type I diabetes mellitus. Hepatitis C virus infection is an important public health issue worldwide. Egypt has the highest prevalence of hepatitis C virus infection of any country in the world. It is estimated to be 8% in urban and 25% in rural areas. We present the case of an Egyptian child with autoimmune polyendocrine syndrome type 2 associated with chronic hepatitis C infection. Case presentation A 14-year-old Egyptian boy with type 1 diabetes mellitus was referred to our institution for an evaluation of recurrent attacks of hypoglycemia of two months duration. The initial clinical examination revealed hypotension as well as vitiligo of the skin. He had high potassium, low sodium, low cortisol, high adrenocorticotropic hormone, slightly high thyroid stimulating levels with strong positivity of anti-thyroglobulin and anti-thyroid peroxidase antibodies. The hepatitis C antibody and hepatitis C virus–polymerase chain reaction were positive. Based on these findings, a diagnosis of autoimmune polyendocrine syndrome type 2 with chronic hepatitis C was made. He was started on hydrocortisone (10mg twice daily), fludrocortisone (0.1mg twice daily) and multiple daily doses of insulin. He showed great improvement of his symptoms on the prescribed treatment. Conclusions The importance of the early diagnosis of autoimmune polyendocrine syndrome type 2 and the possibility of its association with chronic hepatitis C infection should be considered in order to implement the proper management of such cases.</p
Holoprosencephaly in an Egyptian baby with ectrodactyly-ectodermal dysplasia-cleft syndrome: a case report
Abstract Introduction Ectrodactyly-ectodermal dysplasia-cleft lip or palate syndrome (OMIM No. 129900) is characterized by the triad of ectrodactyly, ectodermal dysplasia and facial clefting (of the lip and/or palate). Holoprosencephaly denotes a failure in the division of the embryonic forebrain (prosencephalon) into distinct lateral cerebral hemisphere. The association between ectrodactyly-ectodermal dysplasia-cleft lip or palate syndrome and holoprosencephaly is very rare. Here we report holoprosencephaly in an Egyptian infant with ectrodactyly-ectodermal dysplasia-cleft lip or palate syndrome. Case presentation An 11-month-old Egyptian female baby was referred to our institution for an evaluation of poor growth; the pregnancy and perinatal history were uneventful. On examination, her growth parameters were below the third centile, she had bilateral ectrodactyly of both hands and feet, dry rough skin, sparse hair of the scalp and operated right cleft lip and cleft palate. Computerized tomography of her brain revealed holoprosencephaly. Conclusion The importance of the early diagnosis of this syndrome should be emphasized in order to implement a multidisciplinary approach for proper management of such cases.</p
