The clinical, haematological and biochemical features of 50 Sudanese patients with sickle cell disease (SCD) were determined. Of 23 patients with complete family data, 21 had sickle cell anaemia (homozygous HbSS), 2 had sickle-cell/beta+thalassaemia but none had sickle cell/beta Othalassaemia. The remaining 27 patients had HbSS phenotype. 84% of patients were from the Baggara tribe in western Sudan, where HbS is a natural extension of the west African HbS belt. 21 patients were children under 2 years old; 19 were 3-10 years old; and the remaining 10 were over 10 years old. Young patients presented mainly with painful vaso-occlusive crisis, severe anaemia, hand and foot syndrome, fever, underweight, malnutrition and various infectious diseases. All patients had mild to moderate cardiac enlargment; 42% had a moderately enlarged spleen but only 10% had an enlarged liver; 20% had infarctive lesions of long bones and another 8% had Salmonella osteomyelitis. Leg ulcers, priapism, enuresis and cholelithiasis were not observed. Patients had a mean haemoglobin concentration of 7.3 g/dl; reticulocyte count of 15.1%; serum bilirubin of 2.1 mg/dl; HbA2 level of 2.8% and HbF of 7%. Thus, the observed pattern of SCD in Sudan is comparable to the severe type described for Africans and not comparable to the benign form found in Shiite Moslem Arabs of Saudi Arabia. 6 adults with mild SCD had HbF levels below 5%. Amelioration of the disease, therefore, does not seem to be related to HbF levels; nor was it possible to relate it to high levels of erythrocyte 2,3-diphosphoglycerate.

Two sisters, eight and six years old, respectively, were admitted to Mackay Memorial Hospital in 1993 with the chief complaints of growth retardation, polyuria and nocturnal enuresis. Poor urinary concentration, sodium wasting, anemia and renal insufficiency were noted during hospitalization. Ultrasonography revealed increased renal echogenicity, loss of corticomedullary differentiation and multiple tiny corticomedullary cysts in both kidneys. Renal histopathology showed mild increase in glomerular mesangial cellularity and matrix, mild focal tubular atrophy with thickening of the tubular basement membrane. Other family members were screened by ultrasonography and found another six patients in two generations of the paternal side. Renal cysts were found in five cases. Three of them had progressively deteriorating renal failure. Five had stable renal function after three years of supportive treatment. Thus, it was concluded that the age of onset does not differentiate medullary cystic disease (MCD) from juvenile nephonophthisis (JN), and that JN and MCD could be considered a clinical complex. The absence of corticomedullary cysts on ultrasonography does not preclude the diagnosis. It is also suggested that any children with clinical symptoms of polyuria, polydipsia, anemia and growth retardation from their early years should be carefully examined, and the family history should be investigated to permit early detection of the disease.

The growing number of people seeking asylum in the Netherlands compromises the provision of adequate medical services to all. This development may have a negative impact on refugee children especially. International literature indicates that many children, especially the ones coming from tropical areas or the ones who resided in refugee camps, are suffering from diseases such as tuberculosis, hepatitis B, anaemia, parasitic diseases, caries, malnutrition, hearing and seeing impairments. Many children have psychosocial problems due to traumatic experiences in their country of origin and/or during their flight. These problems lead to a diversity of complaints such as difficulty to sleep, enuresis, feeding problems and hyperactivity. Both the somatic and the psychosocial problems may impede the growth and development of these children. It is therefore imperative to identify the children at risk and to formulate guidelines for providing medical care to refugee children. Special care should also be given to the housing, the living conditions and the provision of specialised personnel and to limiting the duration of the asylum procedure in the case of families with children and other minors.

The studied population (1000 children and young workers and 250 controls) were interviewed for health complaints and subjected to extensive medical investigations. Health problems are more encountered among the workers than in the controls, which has been attributed to the impact of work on health and to the low socioeconomic background that compels the children to work, which may constitute a potential health problem from the start. The significant health problems include: a) Respiratory system complaints, attacks of cough, chronic bronchitis, bronchial asthma and reduction in FEV1.0/FVC; b) cardiovascular abnormalities including palpitations, sinus tachycardia, anemia, vertigo and syncope; c) gastrointestinal abnormalities including dyspepsia and parasitic infestations; d) neuropsychiatric complaints; and e) other health problems including urinary tract infections, backache, visual impairment, repair of hernia and nocturnal enuresis. The study has been concluded by recommending the use of primary health care approach to child labour, emphasizing the importance of pre-employment and periodical medical examinations for protecting this vulnerable group from work hazards, and expanding the efforts of family planning to reduce family size.

Sickle cell anemia is one of the best studied inherited diseases, and despite being caused by a single point mutation in the HBB gene, multiple pleiotropic effects of the abnormal hemoglobin S production range from vaso-occlusive crisis, stroke, and pulmonary hypertension to osteonecrosis and leg ulcers. Urogenital function is not spared, and although priapism is most frequently remembered, other related clinical manifestations have been described, such as nocturia, enuresis, increased frequence of lower urinary tract infections, urinary incontinence, hypogonadism, and testicular infarction. Studies on sickle cell vaso-occlusion and priapism using both in vitro and in vivo models have shed light on the pathogenesis of some of these events. The authors review what is known about the deleterious effects of sickling on the genitourinary tract and how the role of cyclic nucleotides signaling and protein kinases may help understand the pathophysiology underlying these manifestations and develop novel therapies in the setting of urogenital disorders in sickle cell disease.

This review focuses key advances in different pediatric fields that were published in Italian Journal of Pediatrics and in international journals in 2015. Weaning studies continue to show promise for preventing food allergy. New diagnostic tools are available for identifying the allergic origin of allergic-like symptoms. Advances have been reported in obesity, short stature and autoimmune endocrine disorders. New molecules are offered to reduce weight gain and insulin-resistance in obese children. Regional investigations may provide suggestions for preventing short stature. Epidemiological studies have evidenced the high incidence of Graves' disease and Hashimoto's thyroiditis in patients with Down syndrome. Documentation of novel risk factors for celiac disease are of use to develop strategies for prevention in the population at-risk. Diagnostic criteria for non-celiac gluten sensitivity have been reported. Negative effect on nervous system development of the supernumerary X chromosome in Klinefelter syndrome has emerged. Improvements have been made in understanding rare diseases such as Rubinstein-Taybi syndrome. Eltrombopag is an effective therapy for immune trombocytopenia. Children with sickle-cell anemia are at risk for nocturnal enuresis. Invasive diseases caused by Streptococcus pyogenes are still common despite of vaccination. No difference in frequency of antibiotic prescriptions for acute otitis media between before the publication of the national guideline and after has been found. The importance of timing of iron administration in low birth weight infants, the effect of probiotics for preventing necrotising enterocolitis and perspectives for managing jaundice and cholestasis in neonates have been highlighted. New strategies have been developed to reduce the risk for relapse in nephrotic syndrome including prednisolone during upper respiratory infection. Insights into the pathophysiology of cerebral palsy, arterial ischemic stroke and acute encephalitis may drive advances in treatment. Recommendations on breastfeeding and complementary feeding have been updated. Novel treatments for rhabdomyosarcoma should be considered for paediatric patients. Control of risk factors for bronchiolitis and administration of pavilizumab for preventing respiratory syncytial virus infection may reduce hospitalization. Identification of risk factors for hospitalization in children with wheezing can improve the management of this disease. Deletions or mutations in genes encoding proteins for surfactant function may cause diffuse lung disease.
