Infants may require tracheal intubation if:- direct tracheal suctioning is required- effective bag-mask ventilation cannot be provided- chest compressions are performed- endotracheal (ET) administration of medications is desired- congenital diaphragmatic hernia is suspected, or – a prolonged need for assisted ventilation exists.

Alpha-fetoprotein (AFP) is a plasma protein produced by the embryonic yolk sac and the fetal liver. AFP levels in serum, amniotic fluid, and urine functions as a screening test for congenital disabilities, chromosomal abnormalities, as well as some other adult occurring tumours and pathologies.Pregnant maternal serum AFP levels are elevated in:- Neural tube defects (e.g., spina bifida, anencephaly)- Omphalocele- Gastroschisis- posterior urethral valves- nephrosis- GI obstruction- teratomas

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.

Eight percentage of infantile haemangiomas are focal and solitary. Sixty percent of cutaneous haemangiomas occur on the head and neck, 25% on the trunk, and 15% on the extremities. Haemangiomas also can occur in extracutaneous sites, including the liver, gastrointestinal tract, larynx, CNS, pancreas, gall bladder, thymus, spleen, lymph nodes, lung, urinary bladder, and adrenal glands.Guidelines on the management of infantile haemangioma were released in December 2018 by the American Academy of Paediatrics stating that:Imaging is not necessary unless the diagnosis is uncertain, there are five or more cutaneous infantile haemangiomas present, or there is suspicion of anatomic abnormalities.

Turner syndrome is a genetic disease that affects females. It presents with wide-spread nipples, low hairline, lymphoedema, short 4th metacarpals, high-arched palate, cardiac problems, and horseshoe kidneys.

In the prenatal heart, right-to-left atrial shunting of blood through the foramen ovale is essential for proper circulation. After birth, as the pulmonary circulation is established, the foramen ovale functionally closes as a result of changes in the relative pressure of the two atrial chambers, ensuring the separation of oxygen-depleted venous blood in the right atrium from the oxygenated blood entering the left atrium.

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.

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.

Group B beta-haemolytic Streptococcus (GBS) and Escherichia coli are the most common cause of early sepsis. Group B Streptococcus (GBS), also known as Streptococcus agalactiae, is best known as a cause of postpartum infection and as the most common cause of neonatal sepsis. The GBS organism colonizes the vagina, GI tract, and the upper respiratory tract of healthy humans. GBS infection is almost always associated with underlying abnormalities. In elderly persons aged 70 years or older, GBS infection is strongly linked with congestive heart failure and being bedridden.Penicillin remains the drug of choice for group B streptococcal infection but resistance may occur.

Developmental dysplasia of the hip (DDH) is a spectrum of anatomical abnormalities of the hip joint in which the femoral head has an abnormal relationship with the acetabulum.Plain radiographs are of limited value for diagnosis in the new-born child because the femoral head and acetabulum are largely cartilaginous. Ultrasound scanning is the investigation of choice to evaluate DDH in infants younger than six months of age and is useful to diagnose more subtle forms of the disorder when a clinical exam is equivocal. It is also the only imaging modality that enables a three-dimensional real-time image of a neonate’s hip.

Congenital hypothyroidism (CH) is inadequate thyroid hormone production in new-born infants. It can occur because of an anatomic defect in the gland, an inborn error of thyroid metabolism, or iodine deficiency.CH is the most common neonatal endocrine disorder, and historically, thyroid dysgenesis was thought to account for approximately 80% of cases. However, studies have reported a change in the epidemiology, with a doubling in incidence to around 1 in 1500 live new-borns.​Infants with congenital hypothyroidism are usually born at term or after term. Symptoms and signs include the following:Decreased activityLarge anterior fontanellePoor feeding and weight gainSmall stature or poor growthJaundiceDecreased stooling or constipationHypotoniaHoarse cryProlonged neonatal jaundice or unconjugated hyperbilirubinemia

A monochorionic diamniotic (MCDA) twin pregnancy is a subtype of monozygotic twin pregnancy. An MCDA pregnancy results from a separation of a single zygote at ,4-8 days (blastocyst) following formation. These fetuses share a single chorionic sac but have two amniotic sacs and two yolk sacs. It accounts for the vast majority (70-75%) of monozygotic twin pregnancies although only ,30% of all twin pregnancies. The estimated incidence is at ,1:400 pregnanciesThe layman term is that the twins are identical – in reality, they are phenotypically similar, and of course of the same gender.

The baby may have hydrocephalus and no surgery can be done until it is excluded.Cranial sonography is an important part of neonatal care in general, and high-risk and unstable premature infants, in particular. It allows rapid evaluation of infants in the intensive care units without the need for sedation and with virtually no risk. Expectedly, sonography represents an ideal imaging modality in neonates due to its portability, lower cost, speed, and lack of ionizing radiations. Although there are numerous indications for cranial sonography, it appears to be most useful for detection and follow-up of intracranial haemorrhage, hydrocephalus, and periventricular leukomalacia (PVL).

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

A lumbosacral lipoma is a form of congenital spinal lipoma and can be regarded as a cutaneous marker of dysraphism. It is not a skin condition but rather represents a defect in the process of neurulation and leads to a constellation of other abnormalities. The most common other systemic abnormalities associated with midline lumbosacral lipoma include complex anorectal and urological malformations. Other mentioned conditions are benign rashes or birthmarks.

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.
