Vertically transmitted (mother-to-child) viral infections of the fetus and newborn can generally be divided into two major categories. The second are perinatal infections, which are acquired intrapartum or in the postpartum period. Classifying these infections into congenital and perinatal categories highlights aspects of their pathogenesis in the fetus and newborn infant. Generally, when these infections occur in older children or adults, they are benign. However, if the host is immunocompromised or if the immune system is not yet developed, such as in the neonate, clinical symptoms may be quite severe or even fatal. Congenital infections can have manifestations that are clinically apparent antenatally by ultrasonography or when the infant is born, whereas perinatal infections may not become clinically obvious until after the first few days or weeks of life. When congenital or perinatal infections are suspected, the diagnosis of each of the possible infectious agents should be considered separately and the appropriate most rapid diagnostic test requested in order to implement therapy as quickly as possible. These immunoglobulin G (IgG) antibodies are acquired by passive transmission to the fetus and merely reflect the maternal serostatus. Pathogen-specific IgM antibodies do reflect fetal/infant infection status but with variable sensitivity and specificity. The following discussion is divided by pathogen as to the usual timing of acquisition of infection (congenital or perinatal) and in approximate order of prevalence. A summary of the diagnostic evaluation for separate viral infections is shown in Table 48. It is a member of the herpesvirus family, is found only in humans, and derives its name from the histopathologic appearance of infected cells, which have abundant cytoplasm and both intranuclear and cytoplasmic inclusions. Primary infection (acute infection) is usually asymptomatic in older infants, children, and adults, but may manifest with mononucleosis-like symptoms, including a prolonged fever and a mild hepatitis.

However blood pressure and age cheap bystolic master card, additional studies are needed to compare the long-term neurodevelopmental outcomes of twins after these interventions pulse pressure in aortic regurgitation purchase 5mg bystolic fast delivery. Neonatal management may include resuscitation at birth and need for continued ventilatory and cardiovascular support, rapid establishment of intravascular access for volume expansion to treat hypotension, correction of hypoglycemia, red blood cell transfusion to treat anemia, and partial exchange transfusion in the recipient to treat significant polycythemia. Velamentous cord insertion and vasa previa occur six to nine times more often in twins than in singletons and even more often in higher order gestations. Probable factors contributing to this higher risk include placental crowding and abnormal blastocyst implantation. Twin birth is associated with an increased risk of neonatal mortality compared to singleton births at all gestational ages; the perinatal mortality rate is increased further in second-born twins compared to first-born twins (26. The mortality increases threefold and fourfold for triplet and quadruplet births, respectively. Prematurity and low birth weight are the predominating factors that increase the rates of mortality and morbidity for multiple births. Assisted reproduction has contributed to the increased incidence of multifetal pregnancies, and preterm birth is strongly correlated with the number of fetuses. Therefore, techniques that limit the number of reimplanted eggs or transferred embryos or selective reduction of higher order multiples may improve the likelihood of a successful outcome. Hospital stays for mothers and babies are typically longer for multiple gestations. One study estimated that, compared with singletons, average hospital costs were three and six times higher for twins and triplets, respectively; total family costs were four and 11 times higher, respectively. Thirty-five percent of twins and 75% of triplets resulted from assisted reproduction techniques. Caring for twins or higher order multiples contributes to increased marital strain, financial stress, parental anxiety, and depression and has a greater influence on the professional and social life of mothers of these infants, particularly first-time mothers, compared with mothers of singletons. Social services, lactation support, and assistance from additional caregivers and family members can help parents cope with the increased amount of care required by multiples. Organizations of parents of multiples can provide advice and emotional support that can further help new parents of multiples cope. There are many drugs, exposures, and medications that, when taken in pregnancy, can have an adverse impact on the developing fetus and the infant postnatally. The most recent National Survey on Drug Use and Health (Substance Abuse and Mental Health Services Administration, However, with the growing drug epidemic in this country, it is important that health care providers have an understanding of how these exposures can affect fetuses and infants. The most common illicit drugs abused in the United States are cannabinoids, cocaine, heroin, and methamphetamine. There is also a growing epidemic of narcotic abuse and methadone treatment that is having profound impacts on neonates throughout the country. Alcohol and tobacco are also common exposures during pregnancy, despite their known teratogenic effects and the widespread education against their use. Intrauterine exposure to alcohol occurs more often than all the illicit substances listed in the preceding text combined. It is also difficult to tease out the effects of any one of the drugs, as many of them are taken in conjunction with others. Another increasing trend is the use of psychotropic medications taken during pregnancy, most commonly for treatment of maternal depression, anxiety, and bipolar disorder. Take a comprehensive medical and psychosocial history including a specific inquiry about maternal drug use as part of every prenatal and newborn evaluation. Accurate information regarding illicit drug use during pregnancy is sometimes difficult to obtain. Placental rupture this is a revision of the chapter by Sylvia Schechner in the 6th edition. Urine testing is a quick, noninvasive way to test for drug exposure in the neonate; however, it will only show drug use that occurred within days of delivery. For example, cocaine will remain in the urine up to 3 days after the most recent use, marijuana 7 to 30 days, methamphetamine 3 to 5 days, and opiates (including methadone) 3 to 5 days. Drugs administered during labor may cause difficulty in interpreting urine results. Meconium analysis by radioimmunoassay affords a longer view into the drug-use pattern but is an expensive test and results take longer to obtain. Hair analysis of the infant can reveal maternal drug use during the previous 3 months, but hair grows slowly and recent drug use may not be detected.

Adequate protein for neonates with otherwise normal renal function should be provided unless they are on continuous hemodialysis or peritoneal dialysis hypertension va disability rating purchase bystolic in india. Dialysis is indicated when conservative management has been unsuccessful in correcting severe fluid overload arrhythmia research technology stock order bystolic 5 mg online, hyperkalemia, acidosis, and uremia. Inadequate nutrition because of severe fluid restriction in the anuric infant is a relative indication for dialysis. Because the technical aspects and the supportive care are specialized and demanding, this procedure must be performed in centers where the staff have experience with dialysis in infants and neonates. The severity of renal impairment in these diseases varies from extreme oligohydramnios and in utero compromise to late presentation in Fluid Electrolytes Nutrition, Gastrointestinal, and Renal Issues 367 adulthood. Ultimately, the prognosis depends on the severity of the anomaly, whether the contralateral kidney is viable and on extrarenal organ dysfunction. In the newborn course, the degree of pulmonary hypoplasia will dictate the likelihood of viability. Blood pressure rises with postnatal age, 1 to 2 mm Hg/day during the first week and 1 mm Hg/week during the next 6 weeks in both the preterm and full-term infant. Normative values of blood pressure for full-term infants and premature infants are shown in Tables 28. Hypertension is defined as persistent blood pressure 2 standard deviations above the mean. The three most common causes of hypertension in newborns are secondary to bronchopulmonary dysplasia, umbilical artery thrombus emboli, and coarctation of the aorta. History and physical examination, a review of fluid status, medications, location of arterial thrombus, and weak distal pulses, may provide clues about the underlying etiology. Renin-mediated hypertension and fluid overload may both contribute to renal causes of hypertension. Urinalysis, renal function studies, serum electrolyte levels, and renal ultrasonographic examination should also be obtained. Color Doppler flow studies may detect aortic or renal vascular thrombosis, although this test is not reliable with the possibility of both false positives and false negatives. Echocardiogram is indicated if coarctation is suspected and can determine if left ventricular hypertrophy has occurred from sustained hypertension. Other rare causes include congenital hypercoagulable states and severe hypotension. While the management is controversial, potential options include surgical thrombectomy, thrombolytic agents, and conservative medical care, including antihypertensive therapy. There have been reports of longterm complications with hypertension and/or proteinuria and progression to renal failure in adolescence (see Chap. The classic clinical findings include gross hematuria often with clots, enlarged kidneys, hypertension, and thrombocytopenia. Other symptoms include vomiting, shock, lower extremity edema, and abdominal distention. Initial therapy should focus on the maintenance of circulation, fluid, and electrolyte balance while examining for underlying predisposing clinical conditions. If there is bilateral involvement and Fluid Electrolytes Nutrition, Gastrointestinal, and Renal Issues 371 Table 28. Recently, low-molecularweight heparin has been used both as initial treatment for thrombosis and as prophylactic therapy after recannulization of the occluded vessel. In the treatment of patients with thrombosis, dosages of 200 to 300 anti-Fxa U/kg are reported to reach a therapeutic level of 0. Reported dosages range from 45 to 100 anti-Fxa U/kg to reach prophylactic levels of 0. Protamine and e-caproic acid should be present at the bedside because significant bleeding can occur. Surgical intervention should be considered if there has been an indwelling umbilical vein catheter, the thrombosis is bilateral, and involves the main renal veins leading to renal failure. Proteinuria in small quantities during the first weeks of life is frequently found. After the first week, persistent proteinuria 250 mg/m2/day should be investigated (Table 28. In general, mild proteinuria reflects a vascular or tubular injury to the kidney, or the inability of the immature tubules to reabsorb protein.

Insulin therapy has been shown as more effective in lowering serum [K+] in extremely premature infants with nonoliguric hyperkalemia in a randomized controlled trial arteria gastroepiploica dextra cheap bystolic online mastercard. This probably results from the increased prevalence of antenatal steroid exposure arrhythmias in children generic bystolic 2.5 mg on line. Therefore the clinician should be particularly vigilant in checking for nonoliguric hyperkalemia in extremely preterm infants whose mothers have not received antenatal steroids before their birth. Other causes of hyperkalemia of which to be cognizant are oliguric acute renal failure and drugs that inhibit K excretion. In this circumstance inhalation treatment with albuterol is most rapidly effective. Glucose and insulin infusion versus kayexalate for early treatment of non-oliguric hyperkalemia in very-low-birth-weight infants. Potassium metabolism in extremely low birth weight infants in the first week of life. Glucose and insulin versus cation-exchange resin for the treatment of hyperkalemia in very low birth weight infants. Effect of prenatal steroids on potassium balance in extremely low birth weight neonates. Efficacy of albuterol inhalation in treatment of hyperkalemia in premature infants. Salbutamol versus cation-exchange resin (Kayexalate) for the treatment of nonoliguric hyperkalemia in preterm infants. Hydrogen ion concentration ([H+]) is measured potentiometrically using a complicated system that employs two electrodes (usually Ag/AgCl) designed such that the potential between them is sensitive to the [H+] in the intervening medium. Because pH is defined as the negative log [H+], pH decreases as [H+] increases and increases when [H+] decreases. Note: Unfortunately, as a result of expressing pH as -log[H+], the proportional change in [H+] is masked. The partial pressure of oxygen is measured amperometrically by the Clark electrode. The hydrogen ions produced by this reaction are then measured as previously described. The semipermeable membrane ensures that this measurement is completely independent of blood pH. The effect of these buffers is to establish and stabilize a pH of blood at approximately 7. When measured, buffer base is the number of millimoles of strong base or strong acid needed to titrate 1 L of blood (Hgb = 15 g/dL) to pH = 7. These differences in normal serum bicarbonate levels with maturation result from the increased capacity of the mature kidney to conserve bicarbonate and to excrete [H+]. This is the result of immaturity of carbonic anhydrase in the renal tubules and the intercalated cells of the collecting duct. Do infants excrete more or less titratable acid and ammonia per kilogram of body weight compared with older children Titratable acid is a term to describe acids such as phosphoric acid and sulfuric acid, which are involved in acid excretion. The titratable acid excretion rate in term infants younger than 1 month old is about one half of adult values, and the ammonium excretion rate about two thirds that of older children and adults. After 1 month of age the net acid excretion rate in term infants is similar to that in older children and adults when expressed per 1. Preterm infants also increase their rates of titratable acid and ammonium excretion with maturation, but these rates still remain lower than in term infants, even up to the age of 4 months. How can the oxygen saturation value reported with the blood gas be used clinically

She has had type 2 diabetes for 6 years now and has been on oral medications for blood sugar control hypertension 160100 purchase line bystolic. After delivery heart attack ekg buy bystolic 5mg otc, her newborn will be at risk for: A Elevated blood glucose B Low hematocrit C Low calcium D Elevated potassium E Low bilirubin 2. She has been followed by her primary and was on inhaled glucocorticoids which she stopped when she had a positive pregnancy test. A Start aminophylline B Educate her regarding use of beta-agonist inhalers C Restart her inhaled glucocorticoids D Prescribe a course of oral steroids E Start daily nebulized beta-agonists 3. A 28-year-old woman, gravida 2, para 1, at 20 weeks of gestation, presents with increased sweating and palpitations. A Propranolol B Methimazole C Propylthiouracil D Potassium iodide E Fetal ultrasound 4. An 18-year-old woman, gravida 3, para 2, at 28 weeks of gestation, is admitted with right-sided back pain, fever, chills, and severe nausea. She has bilateral costovertebral angle tenderness, with greater discomfort on the right side. A 20-year-old woman just delivered a viable male neonate at 38 weeks of gestation after being a restrained passenger in a car accident. Upon arriving at the emergency department she was "cleared" by the trauma and orthopedic teams and sent to the labor and delivery floor. After obtaining her prenatal information you realize she is Rh negative and antibody D negative. A diabetic woman is at higher risk for delivering a baby with respiratory distress, hypoglycemia (low glucose), hypocalcemia (low calcium), polycythemia (high hematocrit), and hyperbilirubinemia (high bilirubin). Those with severe asthma may require courses of oral steroids for control when inhaled glucocorticoids and beta-agonists are not sufficient. Beta-blockers are the initial treatment of choice for her symptoms of tachycardia and palpitations. A fetal ultrasound would be appropriate given the disparity between the gestational age and the fundal height. The clinical scenario presented is that of pyelonephritis that is not responding to treatment. This finding should always prompt radiologic evaluation to rule out an abscess or renal calculi. The least invasive initial procedure is a renal ultrasound, not an intravenous pyelogram. There is no need to repeat the urine culture or to change her antibiotics since results of her initial urine culture and sensitivity confirm that she is on appropriate antibiotics. If the baby is Rh negative, then there is no need for Rh immune globulin because the maternal immune system would not form any antibodies directed toward fetal red blood cells. Many women see their gynecologist for routine health maintenance, in addition to preventive care and treatment for gynecologic conditions. The gynecologic office visit differs for adolescents, premenopausal, and postmenopausal women, but at all ages serves to address the unique aspects of reproductive health as well as primary and preventative care. The practitioner must be particularly sensitive to the unique needs and communicative style of an adolescent female. She may welcome the continued presence and comfort of her guardian during the history and physical examination. As she feels more comfortable with accessing healthcare and matures, she will eventually visit with the provider alone. However, this is typically during the late teen years or once sexual activity has been initiated (see Chapter 20). Allow the adolescent to speak and describe the condition to the best of her ability and then complete the history through involvement of the parent. Begin the visit by asking questions regarding neutral topics to establish rapport. Performance in school: affords a picture of the home environment, intellect, and general well-being. Regular menses are a reliable sign of ovulation, and conversely, oligomenorrhea often signals anovulation.
