Tuberculin sensitivity or post vaccinial allergy (PVA) is widely used as an indicator of successful BCG vaccination. The protection conferred by BCG vaccination, the duration of post-vaccinial allergy and the relationship between the two remain a subject of controversy. The present study was conducted with the aim of finding the duration of PVA and evaluate the need for revaccination. One thous...

Introduction: Preterm infants suffer a number of health risks, one of which is post-hemorrhagic ventricle dilation (PHVD), which occurs when fluctuations in their blood pressure cause a rupture between blood vessels and the ventricles where cerebrospinal fluid (CSF) is generated. Blood seeping through the rupture clots, blocking CSF from circulating through the central nervous system. The build...

This is a brief review of neonatal chronic lung disease, sometimes called the 'new bronchopulmonary dysplasia (BPD)'. The clinical, radiographic and pathological features of this condition have changed considerably in recent years because of major advances in perinatal care, including widespread use of antenatal glucocorticoid therapy, postnatal surfactant replacement and improved respiratory a...

Background: Tetanus has remained a major public health problem worldwide although it is a vaccine preventable disease. It is a major contributor to under-five morbidity and mortality globally. Its effect is worse in developing countries such as Nigeria. Aims and Objectives: To highlight the socio-economic challenges in the management of Post neonatal tetanus at the University of Port Harcourt T...

Objective: Preterm infants are prone to intraventricular hemorrhage. They may suffer from significant morbidity and mortality particularly in those with high-grade hemorrhage. Our objective was to determine the incidence of intraventricular hemorrhage in premature infants transported to a tertiary center compared with those delivered at the level III facility.  Methods: We evaluated all prematu...

Background: In mammalian ovaries, loss of over two-thirds of germ cells happens due to cell death. Nonetheless, the exact mechanism of cell death has yet to be determined. The present basic practical study was designed to detect 3 types of programmed cell death, namely apoptosis, autophagy, and necrosis, in murine embryonic gonadal ridges and neonatal ovaries.Methods: Twenty gonadal ridges and ...

Pulmonary lymphangiectasia (PL) is a rare condition characterized by dilatation of the lymphatic vessels. Post-neonatal PL is usually associated with pleural effusion and should therefore be suspected in the presence of chylothorax. We describe a post-neonatal manifestation of PL in a 7-year-old boy presenting chylothorax. Radiological examinations included thorax X-ray, ultrasound, and compute...

Male neonate brains are more susceptible to the effects of perinatal asphyxia resulting in hypoxia and ischemia (HI)-related brain injury. The relative resistance of female neonatal brains to adverse consequences of HI suggests that there are sex-specific mechanisms that afford females greater neuroprotection and/or facilitates recovery post-HI. We hypothesized that HI preferentially induces es...
