Epidemiology of Common Neurosurgical Diseases in the Neonate

Bladder augmentation in children: current problems and experimental strategies for reconstruction

Bladder augmentation is a demanding surgical procedure and exclusively offered for selected children and has only a small spectrum of indications. Paediatric bladder voiding dysfunction occurs either on a basis of neurological dysfunction caused by congenital neural tube defects or on a basis of rare congenital anatomic malformations. Neurogenic bladder dysfunction often responds well to a combination of specific drugs and/or intermittent self-catheterization. However, selected patients with spinal dysraphism and children with congenital malformations like bladder exstrophy and resulting small bladder capacity might require bladder augmentation. Ileocystoplasty is the preferred method of bladder augmentation to date. Because of the substantial long-and short-term morbidity of augmentation cystoplasty, recent studies have tried to incorporate new techniques and technologies, such as the use of biomaterials to overcome or reduce the adverse effects. In this regard, homografts and allografts have been implemented in bladder augmentation with varying results, but recent studies have shown promising data in terms of proliferation of urothelium and muscle cells by using biological silk grafts.

Maternal nutrition among women from Sub-Saharan Africa, with a focus on Nigeria, and potential implications for pregnancy outcomes among immigrant populations in developed countries

Pregnant women in countries of Sub-Saharan Africa (SSA) are at risk of poor nutritional status and adverse outcomes as a result of poverty, food insecurity, sub-optimal healthcare facilities, frequent infections and frequent pregnancies. Studies from Nigeria, for example, have revealed a high prevalence of both under- and over-nutrition, as well as nutrient deficiencies, including iron, folate, vitamin D and vitamin A. Subsequently, obstetric complications, including hypertension, anaemia, neural tube defects, night-blindness, low birth weight and maternal and perinatal mortality, are common. Migration patterns from SSA to the Western world are on the rise in recent years, with Nigerians now representing the most prevalent immigrant African population in many developed countries. However, the effect of immigration, if any, on the nutritional status and pregnancy outcomes of these women in their host countries has not yet been studied. Consequently, it is unknown to what extent the nutritional deficiencies and pregnancy complications occurring in Nigeria, and other countries of SSA, present in these women post-emigration. This may result in missed opportunities for appropriate antenatal care of a potential high-risk group in pregnancy. The present review discusses the literature regarding nutrition in pregnancy among SSA women, using Nigeria as an example, the common nutrition-related complications that arise and the subsequent obstetric outcomes. The concept of dietary acculturation among immigrant groups is also discussed and deficiencies in the literature regarding studies on the diets of pregnant immigrant women are highlighted.

Neurological congenital malformations in a tertiary hospital in south Brazil

BACKGROUND

Congenital anomalies are one of the main causes of morbidity and mortality among infants. The involvement of the central nervous system (CNS) occurs in 21% of cases.

OBJECTIVE

To identify incidence of CNS malformations and associated factors in newborns at a Terciary Hospital of Porto Alegre.

METHOD

Case-control study conducted between 2000 and 2005 based on the Latin American Collaborative Study of Congenital Malformations database.

RESULTS

Among 26,588 births registered in this period, 3.67% presented with malformations (IC=95%; 3.44-3.9), being 0.36% of the CNS (IC=95%,(0.29-0.43)). The most common CNS malformation was meningomielocele (10.4%). Young maternal age (p=0.005); low birth weight (p=0.015); large cephalic perimeter (p=0.003); post term birth (p=0.000) and low APGAR indexes at the 1st and 5th minutes were associated with CNS malformations.

CONCLUSION

We found an incidence of CNS malformations similar as compared to literature.

Neonatal surgical emergencies: stabilization and management

The transitional period following birth can be complicated by the presence of congenital anomalies requiring emergent surgical management. Newborns with congenital diaphragmatic hernia require immediate intubation and gastric decompression to minimize gastric distention, as well as cautious ventilation to avoid pneumothorax. Newborns with omphalocele and gastroschisis are at risk for bacterial contamination, as well as heat and evaporative losses from exposed viscera. These newborns benefit from the use of a protective bowel bag. Newborns with meningomyelocele require meticulous care to avoid infection and trauma to exposed portions of the spinal cord. An illustrated protocol provides guidance in the initial stabilization of these defects. Nurses providing family-centered care must be knowledgeable about congenital anomalies presenting at birth so they can properly stabilize these newborns and provide accurate information to families.
