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.

The embryonic period comprises of the first 8 weeks of pregnancy. It is divided into a preembryonic phase (from the 1st to the 3rd week), in which the three germinal layers arise, and into the embryonic phase proper (from the 4th to 8th week), in which the embryonic organ anlagen arise.

In this case there is evidence of disseminated intravascular coagulation (DIC) caused by severe birth asphyxia. The baby was born weighing 4,9 kg which is a large size for a new-born and thus a difficult delivery with potential birth asphyxia.

Synchronized IMV (SIMV) with pressure support, used in the alert infant. SIMV guarantees a minimum minute volume while allowing the patient to trigger spontaneousbreaths at a rate and volume determined by the patient. Extra breaths are boosted with pressure support. Tidal Volume (Vt) is normally approximately 6-10 mL/kg and 4-6 ml/kg in the preterm.Respiratory rate (RR) is usually 30-60 BPM. Tidal volume and respiratory rate are relatedto respiratory minute volume as follows: Vm(mL/min) = Vt x RR .This baby is overventilated with a low CO2. Tidal volumes should generally be targeted at 4–6 ml/kg and this baby is being targeted at 9 ml/kg which exposes the baby to damage to the distal airways from this ventilation which can lead to bronchopulmonary dysplasia.

Breastfeeding may be significantly impaired (up to 25%) by breast augmentation. Equally, breast engorgement, which occurs due to vascular congestion, reduces nipple protrusion and subsequent ability to breastfeed successfully. In the latter, regular feeding or expressing is required.

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.

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.

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.

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

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.

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

Congenital hypothyroidism results from insufficient levels of thyroid hormone in the body since birth, which is either due to dysgenesis of the thyroid gland or dyshormonogenesis. The important features of this disease include coarse facial features (macroglossia, large fontanelles, depressed nasal bridge, hypertelorism, etc.), failure to thrive, cardiomegaly, hypotonia, umbilical hernia, and low core body temperature among many others. Frontal bossing is the usual feature of rickets and acromegaly. Mitral regurgitation is not usually associated with congenital hypothyroidism.

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.

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.

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.

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

EPICure is a series of studies of survival and later health among babies and young people who were born at extremely low gestations – from 22 to 26 weeks.Boost II is a double-blind randomised controlled trial (RCT) comparing the effects of targeting arterial oxygen saturations between 85% and 89% versus 91% and 95% in preterm infants.OSCAR Xe is not the name of a study. Baby-OSCAR is an RCT to determine whether a confirmed large patent ductus arteriosus in very premature babies should be treated with ibuprofen within 72 hours of birth.SafeBoosC is a trial to examine if it is possible to stabilise the cerebral oxygenation of extremely preterm infants in the first 72 hours of life with the use of NIRS oximetry and a clinical treatment guideline. TOBY Xe is an RCT looking at the neuroprotective effects of hypothermia combined with inhaled xenon following perinatal asphyxia.

The origins of the neural tube and the nape of the neck where nuchal translucency measurements are taken are from embryonic ectoderm.The structural development of the head and neck occurs between the third and eighth weeks of gestation. The 5 pairs of branchial arches, corresponding to the primitive vertebrae gill bars, that form on either side of the pharyngeal foregut on day 22 are the embryologic basis of all the differentiated structures of the head and neck. Each arch consists of 3 layers: an outer covering of ectoderm, an inner covering of endoderm, and a middle core of mesenchyme. These arches are separated further into external, ectoderm-lined pharyngeal clefts and internal, endoderm-lined pharyngeal pouchesA population of ectodermal cells adjacent to the neural fold and not included in the overlying surface (somatic) ectoderm gives rise to the formation of the neural crest. These neuroectodermal crest cells are believed to migrate widely throughout the developing embryo in a relatively cell-free enriched extracellular matrix and differentiate into a wide array of cell and tissue types, influenced by the local environment. Most connective and skeletal tissues of the cranium and face ultimately come from the derivatives of neural crest cells.

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.

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.

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.

One of the most common congenital viral infections is cytomegalovirus infection. It is caused by herpesvirus type 5. 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.

Usually, a total serum bilirubin level test is the only one required in an infant with moderate jaundice who presents on the second or third day of life without a history and physical findings suggestive of a pathologic process. Measurement of bilirubin fractions (conjugated vs unconjugated) in serum is not usually required in infants who present as described above. However, in infants who have hepatosplenomegaly, petechiae, thrombocytopenia, or other findings suggestive of hepatobiliary disease, metabolic disorder, or congenital infection, early measurement of bilirubin fractions is suggested. The same may apply to infants who remain jaundiced beyond the first 7-10 days of life, and to infants whose total serum bilirubin levels repeatedly rebound following treatment.

Transient tachypnoea of the new-born (TTN) is the commonest cause of respiratory distress in new-borns and self-limiting. It can affect any new-born shortly after birth. Its most prominent feature is tachypnoea. Nasal flaring, grunting, or intercostal retractions may also be present.

Congenital heart defects are common (40-50%)| they are frequently observed in patients with Down syndrome who are hospitalized (62%) and are a common cause of death in this aneuploidy in the first 2 years of life.The most common congenital heart defects are the following:- Endocardial cushion defect (43%), which results in atrioventricular septal defect (AVSD)/AV canal defect- Ventricular septal defect (32%)- Secundum atrial septal defect (10%)- Tetralogy of Fallot (6%)- Isolated patent ductus arteriosus (4%).About 30% of patients have more than one cardiac defect. The most common secondary lesions are patent ductus arteriosus (16%), atrial septal defect, and pulmonic stenosis (9%). About 70% of all endocardial cushion defects are associated with Down syndrome.Valve abnormalities, such as mitral valve prolapse or aortic regurgitation may develop in up to 40-50% of adolescents and adults who were born without structural heart disease.

Polycythaemia is described as an abnormal increase in the red cell mass. As this influences hyper-viscosity, a peripheral venous sample of blood haematocrit can be used to determine the packed cell volume. Polycythaemia is present if the venous haematocrit is >65% or <22g/dl if converted into a haemoglobin value. Though it is the method of choice for screening, capillary blood samples obtained though heel pricks in new-born may be as much as 15% higher than venous samples and thus high values must be confirmed with a venous sample.

Most infants have a good heart rate after birth and establish breathing by about 90 s. If the infant is not breathing adequately aerate the lungs by giving 5 inflation breaths, preferably using air. Until now the infant’s lungs will have been filled with fluid.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzyme deficiency in humans.It has a high prevalence in persons of African, Asian, and Mediterranean descent. It is inherited as an X-linked recessive disorder.G6PD deficiency is polymorphic, with more than 300 variantsG6PD deficiency can present as neonatal hyperbilirubinemia. Besides, persons with this disorder can experience episodes of brisk haemolysis after ingesting fava beans or being exposed to certain infections or drugs. Less commonly, they may have chronic haemolysis. However, many individuals with G6PD deficiency are asymptomatic.Most individuals with G6PD deficiency do not need treatment. However, they should be taught to avoid drugs and chemicals that can cause oxidant stress. Infants with prolonged neonatal jaundice as a result of G6PD deficiency should receive phototherapy with a bili light.

Umbilical vein catheterization utilizes the exposed umbilical stump in a neonate as a site for emergency central venous access up to 14 days old. Umbilical vein catheterization can provide a safe and effective route for intravenous delivery of medications and fluids during resuscitation.The indication for umbilical vein catheterization is when there is a need for IV access in a neonate for resuscitation, transfusions, or short-term venous access when otherwise unobtainable.
