METHODS： Consecutive infants were enrolled at birth and screened for ROP. We used the UK ROP guideline （May 2008） for infant selection, follow up and treatment. Repeat examinations were performed until retinal vascularisation was complete. RESULTS： Fifty-two infants were enrolled： 24 males and 28 females. Mean gestational age was 31.3wk （±2.8 SD） and mean birth weight was 1234,6 g （±221.1 SD）. Incidence of ROP was 36.5% （stages 1, 2, 3 and 4a were 9.6%, 9.6%, 15.4% and 1.9% respectively）, no stages 4b or 5 were found in this series. Six infants （11.5%） died during screening without ROP, 25 infants （48.1%） were discharged from screening with retinal vascularisation reaching zone III, 5 infants （9.6%） were treated with indirect diode with or without additional cryotherapy and 16 infants （30.8%） were lost to follow up. In this series gestational age rather than birth weight was found significantly correlated and predictive （P〈0.05） with ROP stages. CONCLUSION： ROP in a single site in upper Egypt appears to have comparable incidence to other areas worldwide. The main screening obstacle was missing cases due to the absence of a national ROP screening protocol.展开更多

If not diagnosed and treated properly, it may cause severe neurological disorders during growth. The most frequent difficulties are found in school performance, difficulties in concentration, hyperactivity or fatigue and damage on the onset of puberty. Starting levothyroxine as a drug of choice is essential, and it should be made according to the age and weight of the child. Laboratory tests for control should be requested periodically, along with a strict control of the child’s development and growth. The family-doctor relationship, along with a clear guidance on the importance of treatment, is critical to achieve a successful treatment. This article is a review about the main clinical features of hypothyroidism in childhood, especially in developing countries, providing key aspects of adherence and characteristics of its follow-up.展开更多

Further combined loading tests with phenylalanine(Phe) (100*!mg/kg) and tetrahydrobiopterin (BH4) (7.5*!mg/kg) were performed in suspected patients with abnormal urinary pterin profiles. Gene mutation analysis was performed for patients with BH4 deficiency and their parents. BH4 deficient patients were treated with BH4 and neurotransmitter precursors after diagnosis. Blood phenylalanine levels, clinical symptoms and mental development were followed up.Results Eleven patients were diagnosed as having BH4 deficiency caused by 6-pyruvoyl tetrahydropterin synthase (PTPS) deficiency. The incidence of tetrahydrobiopterin (BH4) deficiency among patients with hyperphenylalaninemia (HPA) in southern Chinese was 10%. Combined loading tests with phenylalanine and oral BH4 were done in 4 of 11 patients and their phenylalanine levels were decreased to normal 4-6h after BH4 administration. Four different mutations (P87S, N52S, D96N and G144R) in the PTPS gene were detected in 5 families. Five PTPS-deficient patients were treated with synthetic BH4, neurotransmitter precursors (L-dopa plus carbidopa, and 5-hydroxytryptophan). They had satisfactory physical and mental development after treatment. One patient with partial PTPS deficiency had normal growth and mental development without treatment. Conclusions Our results emphasize that screening for BH4 deficiency should be carried out in all patients with hyperphenylalaninemia in order to minimize the misdiagnosis. Patients with BH4 deficiency should be treated early with BH4 and a combination of neurotransmitter precursors.展开更多
