Placenta previa and its accompanying fetomaternal complications are increasing day by day because of globally increasing rates of cesarean deliveries, trends of assisted reproductive techniques, and delaying pregnancies to later ages. Placenta previa is an important contributor to iatrogenic and mostly emergent preterm deliveries, which add to increased neonatal morbidity and mortality. The predictors of preterm deliveries can help clinician make necessary preparations for optimal fetomaternal outcome. The aim of the current study was to determine relationship of placental edge thickness and cervical length with gestation at delivery in patients having placenta previa. ⋯ There is linear inverse relationship of placental edge thickness with gestation at delivery. The relationship of cervical length with gestation is positive linear. Patients with thick placental edge are more likely to deliver preterm than those having thin placental edge.

Owing to high proliferation rate, multipotency and self-renewal capability, dental pulp stem cells (DPSC) and stem cells from human exfoliated teeth (SHED) have become stem cell source of choice for cell based regenerative therapies. We aimed to compare DPSC and SHED as stem cell sources with a future use in regeneration of calcified tissue. ⋯ Cultured DPSC and SHED were proliferative and exhibited self-renewal property. Both DPSC and SHED expressed stem cell markers and were able to differentiate into bone, fat and cartilage like cells. Thus, these could be a suitable stem cell sources for cell based regenerative therapies.

To investigate the diagnostic effect of lung ultrasound on neonatal respiratory distress syndrome (NRDS) and to analyze the clinical application value of pulmonary ultrasound score. ⋯ Lung ultrasound has a high diagnostic value in diagnosing NRDS, and lung ultrasound score can evaluate the severity of NRDS in babies to further optimize the diagnosis results, which has important clinical significance.

To investigate the correlation between Helicobacter pylori (Hp) infection and Iron deficiency (ID) in children. ⋯ Hp infection is not a combined risk factor for the development of ID in children. The influence of family social and economic factors should be taken into consideration when analyzing the correlation between Hp infection and ID.

To study the effects of melatonin in preventing neonatal neuronal apoptosis induced by maternal hypothyroidism. ⋯ Intake of melatonin during pregnancy and lactation protected the brains of offspring from extensive apoptosis during maternal hypothyroidism.
