Aim: The most important function of vitamin B12 is to accomplish DNA synthesis, which is necessary for cell division and proliferation. Deficiency of vitamin B12 causes megaloblastic anemia, retardation of growth, and delay in neuromotor maturation. Newborns whose mothers have vitamin B12 deficiency are born with low vitamin B12 storages, and are at risk in terms of vitamin B12 deficiency symptoms during infancy. The aim of our study was to investigate the frequency of anemia and deficiency of vitamin B12, folic acid, and iron in pregnant women living in our region, in their newborn babies, and during the infancy period of these babies. Another aim of our study was to investigate the correlation between the levels of these vitamins in newborns and in their mothers. Material and Methods: In our study, 250 pregnant women at 38–42 gestational weeks, who were admitted for delivery to Gynecology and Obstetrics Clinic and their babies with a birth weight over 2500 g were included in the study. Results: We determined that 24.8% of the pregnant women had anemia, 28% had low ferritin levels, 90.4% had vitamin B 12 deficiency, and 22.4% had folic acid deficiency. Some 3.2% of the newborns had anemia, 2.8% had low ferritin levels, and 72.4% had vitamin B12 deficiency. Among the infants who presented for a follow-up visit at 6 months of age, 22.3% had anemia, 14.9% had low ferritin levels, 40.4% had vitamin B12 deficiency, and 1.06% had folic acid deficiency. In addition, we found that the levels of vitamin B12 and folic acid in newborns were related to the levels of vitamin B12 and folic acid in their mothers. Conclusion: Development of low vitamin B12 stores in newborns and the development of vitamin B12 deficiency during infancy, which may result in irreversible complications including neurologic complications, can be prevented by preventing vitamin B12 deficiency during pregnancy.

Leukoerythroblastosis has to be kept in mind if a very high leukocyte count is detected in the neonatal period, and parvovirus B19 infection should be taken into consideration as the etiological factor for this entity.

ÖZMetanefrik adenomlar (MA) embriyonik metablastemden köken alan iyi huylu renal neoplazmlardır. Nefroblastoma veya Wilms tümörü ile histogenetik bağ olmasına rağmen, çocukluk çağında nadiren görülür. MA'lar genellikle farklı endikasyonlar için yapılan görüntüleme çalışmalarında rastlantısal olarak saptanır. Bazen malign renal tümör olarak yanlış tanı ile stres oluşturabilir ve gereğinden fazla cerrahi girişime neden olabilir. Bu makalede, parsiyel nefrektomi yaptığımız MA'lu 3 yaşındaki kız hastayı sunduk. Nadir görülen MA'un tanısal zorlukları ve takip özelliklerine odaklanarak, önerilen tedavi girişimlerini tartıştık.Anahtar kelimeler: Metanefrik adenom, Wilms tümörü, parsiyel nefrektomi, çocuklarda renal neoplazmlar ABSTRACT Metanephric adenomas (MAs) are benign renal neoplasms that originate from the embryonic tissue of renal medulla. Although there is histogenetic bond with nephroblastoma or Wilms tumor, it is seen rarely in pediatric population. Generally MAs are detected incidentally in imaging studies performed for different indications.. MA can sometimes be misdiagnosed as a malignant renal tumor, and causes unnecessary stress leading to overtreatment. We presented a 6-year-old female with MA who underwent partial nephrectomy and discussed the recommended therapeutic interventions by focusing on the diagnostic challenges and follow-up features of these rare tumors.
