Doctors must perform an infection screen and treat with intravenous antibiotics for at least 48 hours pending results to prevent neonatal sepsis. Risk factors for neonatal sepsis include rupture of the membranes. Risk factors for neonatal sepsis include rupture of membranes greater than 12–24 hours, intrapartum maternal pyrexia (> 38°C), fetal tachycardia, chorioamnionitis, pre-term birth and maternal colonisation with group B Streptococcus. In this case there are two risk factors: prolonged rupture of membranes, and pre-term birth.

Ideally, the test is done in the first 4 to 5 weeks, but it can be done at up to 3 months of age.The identification of all new-borns with hearing loss before age 6 months has now become an attainable realistic goal. In the past, parents and paediatricians often did not suspect a hearing loss until the age of 2-3 years, after important speech and language milestones have not been met. By the time these milestones are missed, the hearing-impaired child has already experienced irreversible delays in speech and language development.

Developmental dysplasia (DDH) of the hip refers to patients who are born with a dislocated or unstable hip due to abnormal development of the hip. Female infants and first born infants are most likely to present with DDH. Other risk factors for DDH include, breech positioning, oligohydramnios, high birth weight or post date babies.

Persistent pulmonary hypertension of the new-born is secondary to the failure of normal circulatory transition at birth, leading to an abnormally high pulmonary vascular resistance. This elevated resistance causes right-to-left shunting of blood and hypoxemia. It can be caused by parenchymal lung diseases (meconium aspiration syndrome, pneumonia or ARDS), lung hypoplasia (like occurring in oligohydramnios or diaphragmatic hernia), or it can be idiopathic. Other possible causes include maternal indomethacin use, group B streptococcal septicaemia, and high-pressure ventilation. Duct dependent congenital heart disease does not lead to persistent pulmonary hypertension.

The baby most likely has umbilical granuloma – granulation tissue may persist at the base of the umbilicus after cord separation| the tissue is composed of fibroblasts and capillaries and can grow to more than 1 cm.Medical therapy is indicated only when an infection is present.Silver nitrate application to umbilical granulomas is usually successful. One or more applications may be needed. Care must be taken to avoid contact with the skin. Silver nitrate can cause painful burns. Small umbilical granulomas with a narrow base may be safely excised in the office setting. Large granulomas and those growing in response to an umbilical fistula or sinus do not resolve with silver nitrate and must be surgically excised in the operating room setting.

Intrauterine growth restriction refers to the failure of the fetus to grow in accordance with the weeks of gestation. There are two types of growth restriction, symmetrical and asymmetrical. Causes include various genetic abnormalities, fetal infections, maternal health conditions, etc. Risk factors for the development of IUGR include fetal echogenic bowel, maternal age above 40 years, low PAPP-A levels, maternal smoking or cocaine use, etc. Fetal echogenic bowel implies a brighter than usual fetal intestines on ultrasonography. It is a marker associated with trisomy 21, which is a cause of IUGR.

In this particular case, the symptoms and signs are suggestive for congenital dislocation of the hip. There are several risk factors present including, a breech delivery, female gender (female:male = 6:1) and oligohydramnios. It is also more common in the left hip than the right.

There are four types of IVH. These are called grades and are based on the degree of bleeding.Grades 1 and 2 involve a smaller amount of bleeding. Most of the time, there are no long-term problems as a result of the bleeding. Grade 1 is also referred to as germinal matrix haemorrhage (GMH).Grades 3 and 4 involve more severe bleeding. The blood presses on (grade 3) or directly involves (grade 4) brain tissue. Grade 4 is also called an intraparenchymal haemorrhage. Blood clots can form and block the flow of cerebrospinal fluid. This can lead to increased fluid in the brain (hydrocephalus).

Benign neonatal sleep myoclonus (BNSM) is a disorder commonly mistaken for seizures during the new-born period. It is characterized by myoclonic lightninglike jerks of the extremities that exclusively occur during sleep| it is not correlated with epilepsy.Causes of neonatal seizures:Hypoxic-ischemic encephalopathy: Hypoxic-ischemic encephalopathy disrupts the ATP-dependent sodium-potassium pump and appears to cause excessive depolarization.Intracranial haemorrhage: occurs more frequently in premature than in term infants. Subarachnoid haemorrhage is more common in term infants. This type of haemorrhage occurs frequently and is not clinically significant. Typically, infants with subarachnoid haemorrhage appear remarkably well. Metabolic disturbances include hypoglycaemia, hypocalcaemia, and hypomagnesemia. Less frequent metabolic disorders, such as inborn errors of metabolism, are seen more commonly in infants who are older than 72 hours. Typically, they may be seen after the infant starts feeding.Intracranial infections (which should be ruled out vigorously) that are important causes of neonatal seizures include meningitis, encephalitis (including herpes encephalitis), toxoplasmosis, and cytomegalovirus (CMV) infections. The common bacterial pathogens include Escherichia coli and Streptococcus pneumoniae.Cerebral malformationsBenign neonatal seizures

A transverse lie is a common malpresentation. It occurs when the fetal longitudinal axis is perpendicular to the long axis of the uterus. The location of the spine determines if the foetus is back up (the curvature of the spine is in the upper part of the uterus) or back down (the curvature of the spine is in the lower part of the uterus).Good antenatal care, ECV, and elective caesarean section are the mainstay of the management.Spontaneous delivery of a term foetus is impossible with a persistent transverse lie and, in general, the onset of labour is an indication for the lower segment caesarean section (LSCS) in a case of a transverse lie.

Hydrops fetalis is a serious condition characterized by excessive fluid accumulation resulting in oedema in one or more of the fetal compartments. The most likely cause is fetal anaemia, and the condition may lead to ascites and pleural effusion. The anaemia that results in hydrops may be caused by Rh incompatibility, Parvovirus B19 infection, toxoplasmosis, hepatitis B, maternal syphilis (strong association), Cytomegalovirus, Turner syndrome, and Noonan syndrome.

Cot death also know as SIDS or Sudden Infant Death syndrome. Putting a baby to sleep on his back has been shown to reduce the risk of SIDS.

Cow’s milk differs in composition to human breast milk. The sodium content of cows milk is too high, which can easily overwhelm a baby’s developing kidneys and lead to hypernatremia and dehydration. In addition to its iron content being too low, cows milk can cause further increase iron deficiency anaemia by irritating the baby’s intestinal lumen and causing blood loss per rectum. After 12 months a baby’s gastrointestinal tract and organs are able to tolerate cows milk.

Fetal alcohol syndrome (FAS) is a common yet under-recognized condition resulting from maternal consumption of alcohol during pregnancy. The diagnosis of fetal alcohol syndrome (FAS) is based on findings in the following 3 areas: (1) characteristic facial anomalies (see image below), (2) growth retardation (intrauterine growth restriction and failure to have catch-up growth), and (3) CNS involvement (cognitive impairment, learning disabilities, or behavioural abnormalities).Key characteristic craniofacial abnormalities include the following:- Smooth philtrum- Thin, smooth vermilion border of the upper lipShort palpebral fissures (< 10th percentile for age)Other craniofacial abnormalities are as follows:- Midface hypoplasia- Microphthalmia- Strabismus- PtosisCNS and neurobehavioral abnormalities include the following:- Microcephaly- Intellectual impairment (mild-to-moderate mental retardation)- Cognitive impairment- Developmental delay- Irritability in infancy- Hyperactivity in childhood or attention deficit hyperactivity disorder (ADHD)- Seizures- Delayed or deficient myelination- Agenesis or hypoplasia of the corpus callosumSkeletal abnormalities include the following:- Radioulnar synostosis- Flexion contractures- Camptodactyly- Aberrant palmar creases, especially hockey-stick palmar crease- Clinodactyly- Klippel-Feil anomaly- Hemivertebrae- Scoliosis- Dislocated jointsOther major congenital anomalies include the following:- Cleft palate- Heart defects- Renal anomalies- DiGeorge sequenceFunctional problems include the following:- Refractive problems (e.g., myopia, astigmatism)- Hearing lossGrowth deficiency includes the following:- Infant small for gestational age (< 10th percentile for weight or length)- Postnatal growth deficiency

Neonatal hypoglycaemia is a serious condition that needs prompt attention and management. The accepted criteria to define neonatal hypoglycaemia is blood sugar levels less than 2.2mmol/L during the first 3 days of life and less than 2.5mmol/L later on. Multiple aetiologies and various risk factors are involved in causing hypoglycaemia in new-borns| the most common and important causes include prematurity, erythroblastosis fetalis, hypoxia at birth, sepsis, inborn errors of metabolism, hypopituitarism, and hyperinsulinism due to maternal diabetes. Inborn errors of metabolism that lead to persistent neonatal hypoglycaemia are maple syrup urine disease, glycogen storage disease, fatty acid enzyme deficiencies, and fructose intolerance. Phenylketonuria does not cause hypoglycaemia.

Risk factors for neonatal death and stillbirth (weak predictive value):- African American race- Advanced maternal age- History of fetal demise- Maternal infertility- History of small for gestational age infant- Small for gestational age infant- Obesity- Paternal age- Poverty and poor quality of careSo in this case the risk factor is the parental unemployment

After a period of 14 days, if jaundice persists in a term new-born, having ruled out the other possibilities, biliary atresia should be considered as a possible diagnosis.Biliary atresia is a rare but serious condition. Symptoms include obstructive jaundice (dark urine and pale stool). Management:Surgery within 8 weeks is recommended. Survival is around 90% using current treatment regimes. Without treatment, children will survive to around 18 months.

Macrosomia can be defined as either a birth weight greater than 4kg or birth weight greater than 90% for the gestational age. Risk factors for macrosomia include maternal diabetes, excessive gestational weight gain, pre-pregnancy obesity, male gender, ethnicity, and advanced gestational age. Genetic conditions associated with macrosomia are Bardet-Biedl syndrome, Perlman syndrome, Beckwith-Wiedemann syndrome, and Prader-Willi syndrome. Silver-Russell syndrome is associated with intrauterine growth retardation and post-natal failure to thrive.

Oligohydramnios is a deficiency in the amniotic fluid volume, measured via ultrasound. Maternal factors associated with oligohydramnios include conditions where there is placental insufficiency such as chronic hypertension, preeclampsia or a thrombotic disorder, post-term pregnancy, premature rupture of membranes, certain chromosomal abnormalities, and obstructions of the foetal urinary tract. On the other hand conditions that are associated with polyhydramnios (excess amniotic fluid) include maternal diabetes, multiple gestations, Rh incompatibility and pulmonary abnormalities.

The withdrawal and withholding of care has been reported in neonatology for over 30 years. ‘Withdrawal’ of life-saving treatment implies the elective discontinuation of ongoing life-supportive measures. ‘Withholding’ of treatment occurs when interventions necessary for immediate survival, such as surgical intervention or resuscitation (bag and mask/endotracheal ventilation, cardiac massage or adrenaline) are deliberately not administered.Withdrawal of treatment most commonly takes the form of withdrawing of ventilatory support. In the extremely premature neonate who has had poor response to bag and mask ventilation, this may mean stopping ventilation breaths, explaining to the parents the reason for discontinuation and offering comfort care according to the parents’ wishes. Parents should be prepared for the sequelae that may follow withdrawal from mechanical ventilation. The infant may become agitated secondary to hypoxia, display terminal gasping and, depending on the size and gestation of their infant, tachypnoea, intercostal recession or stridor may be evident. Parents may want to be involved in the extubation process. Following ventilator withdrawal, the length of time prior to death cannot be predicted and can be a significant cause of parental anguish if this is not explained. A side room and privacy should be made available for the family. NICE guidance suggests that women ‘should not be encouraged to hold their dead baby if they do not wish to’, although this is very much dependent on individuals.

Alpha-fetoprotein has significance primarily as a tumour marker, but maternal levels are frequently measured to detect some of the congenital abnormalities, in which the levels of alpha-fetoprotein are either increased or decreased. The conditions associated with raised alpha-fetoprotein levels are: spina bifida, anencephaly, myelomeningocele, oesophageal atresia, congenital nephrotic syndrome, and turner’s syndrome. Down’s syndrome or trisomy 21 is associated with low levels of maternal alpha-fetoprotein.

Meconium aspiration syndrome (MAS) refers to breathing problems that a new-born baby may have when: – There are no other causes, and- The baby has passed meconium (stool) into the amniotic fluid during labour or deliveryThe most recent guidelines are as follows:- If the baby is vigorous (defined as having a normal respiratory effort and normal muscle tone), the baby may stay with the mother to receive the initial steps of new-born care. A bulb syringe can be used to gently clear secretions from the nose and mouth.- If the baby is not vigorous (defined as having a depressed respiratory effort or poor muscle tone), place the baby on a radiant warmer, clear the secretions with a bulb syringe, and proceed with the normal steps of new-born resuscitation (i.e., warming, repositioning the head, drying, and stimulating). If, after these initial steps are taken, the baby is still not breathing or the heart rate is below 100 beats per minute (bpm), administer positive pressure ventilation.Resuscitation should follow the same principles for infants with meconium-stained fluid as for those with clear fluidContinued care in the neonatal intensive care unit (NICU):Maintain an optimal thermal environment to minimize oxygen consumption.Minimal handling is essential because these infants are easily agitated. Agitation can increase pulmonary hypertension and right-to-left shunting, leading to additional hypoxia and acidosis. Sedation may be necessary to reduce agitation.An umbilical artery catheter should be inserted to monitor blood pH and blood gases without agitating the infant.Continue respiratory care includes oxygen therapy via hood or positive pressure, and it is crucial in maintaining adequate arterial oxygenation. Mechanical ventilation is required by approximately 30% of infants with MAS. Make concerted efforts to minimize the mean airway pressure and to use as short an inspiratory time as possible. Oxygen saturations should be maintained at 90-95%.Surfactant therapy is commonly used to replace displaced or inactivated surfactant and as a detergent to remove meconium. Although surfactant use does not appear to affect mortality rates, it may reduce the severity of disease, progression to extracorporeal membrane oxygenation (ECMO) utilization, and decrease the length of hospital stay.

The perinatal mortality rate is defined as the number of perinatal deaths per 1000 total births. Perinatal death includes the death of a live-born neonate within 7-days of life (early neonatal death) and the death of a fetus ≥ 22 weeks of gestation (stillbirth). Hence, the perinatal mortality rate is calculated by dividing the number of still births+ the number of early neonatal deaths by 1000 births.

A preterm with respiratory distress syndrome presents with the condition as a result of immature lungs and inadequate surfactant production. Management of RDS therefore includes surfactant therapy, oxygen administration and mechanical ventilation, as well as measures such maintaining acid base levels and blood haemoglobin in an intensive care unit. Dexamethasone is not shown to be particularly effective when given to a preterm, but can however be used to prevent or decrease RDS severity when given to the mother before delivery.

After birth, the infant takes its first breath and is exposed to a myriad of stimuli. The pulmonary vessels dilate, and pulmonary vascular resistance (PVR) decreases remarkably while the systemic vascular pressure rises above the PVR. This allows blood from the right ventricle to enter the lungs for oxygenation. In most cases, this increased oxygenation, along with other factors, causes the ductal wall to constrict and the ductus arteriosus to close functionally. As left-sided pressures rise higher than right-sided pressures, the foramen ovale functionally closes. With the clamping of the umbilical cord and the cessation of blood flow, pressures in the portal sinus decrease. This causes the muscle in the sinus wall near the ductus venosus to contract. The lumen of the duct becomes filled with connective tissue, and, in two months, the ductus venosus becomes a fibrous strand embedded in the wall of the liver, thus establishing adult circulation.

Apgar is a quick test performed on a baby at 1 and 5 minutes after birth. The 1-minute score determines how well the baby tolerated the birthing process. The 5-minute score tells the health care provider how well the baby is doing outside the mother’s womb. More specifically, five components are assessed and these are the appearance (A), the pulse (P), the grimace (G), the activity (A) and the respiration (R). A normal APGAR score is considered to be 10 points, 2 points given for each normal component. In this case, 1 point is given for the appearance due to the bluish extremities, 2 points are given for the pulse which is higher than 100 bpm, 1 point is given for the grimacing, 2 points are given for the activity due to the good muscle tone and 1 point is given for the respiration due to gasping. Total score is 7 points.

Neonatal hyperbilirubinemia is a common clinical condition and can be categorized as conjugated and unconjugated hyperbilirubinemia. Conjugated hyperbilirubinemia results from obstructive or hepatocellular causes mainly. The causes of conjugated hyperbilirubinemia include inborn errors of metabolism like galactosemia and aminoaciduria, obstruction from choledochal cysts, and biliary atresia. Long term TPN also leads to conjugated hyperbilirubinemia. Spherocytosis is a hereditary condition belonging to the group of haemolytic anaemias, resulting from plasma membrane protein deficiency. This defect of the RBC plasma membrane decreases their life span, making them osmotically fragile and prone to haemolysis. This leads to an increase in the unconjugated bilirubin levels, with a risk of developing kernicterus.

One of the most common congenital viral infections is cytomegalovirus infection. The infection is even commoner than the other widely known diseases like down’s syndrome and spina bifida. It is caused by herpesvirus type 5 and is diagnosed using PCR of saliva. The clinical features include failure to thrive, intellectual disability, epilepsy, and microcephaly. The most common clinical complication is sensorineural deafness. The drug of choice for the treatment of neonatal CMV infection is ganciclovir, an anti-viral drug that has shown to prevent deafness. Cytomegalic inclusion disease is diagnosed at birth with marked neurological disability, resulting from microcephaly, intracerebral calcifications, and cerebral atrophy.

An important predictor of the foetal well-being is the evaluation of amniotic fluid volumes, commonly done using ultrasonography. Amniotic fluid index (AFI) is calculated by measuring the largest vertical diameter of the fluid pocket in all four quadrants of the uterine cavity and then added together. Oligohydramnios or decreased amniotic fluid volume can be defined as an AFI less than 5cm and occurs in about 4-5% of the pregnancies. It is associated with a number of foetal abnormalities and complications. Foetal abnormalities that lead to oligohydramnios include premature rupture of membranes, intrauterine growth retardation, and congenital foetal abnormalities among others. A single umbilical artery is an anatomical defect of the umbilical cord, which leads to IUGR, uteroplacental insufficiency and may be associated with multiple congenital abnormalities as well, which all ultimately lead to the development of oligohydramnios. It also leads to multiple complications, out of which the incidence of chorioamnionitis is very high. Other complications include fetal growth retardation, limb contractures, GI atresia, and even fetal death.
