After drying, dead tissue and old paint are removed with an emery board or pumice stone. Enough paint to cover the surface of the wart, but not the surrounding skin, is applied and allowed to dry. Warts on the plantar surface should be covered with plasters although this is not necessary elsewhere. Wart paints should not be applied to facial or anogenital skin, or to patients with adjacent eczema. If no progress is being made after the regular and correct use of a salicylic acid wart paint for 12 weeks, then a paint containing formaldehyde or glutaraldehyde is worth trying. A useful way of dealing with multiple small plantar warts is for the area to be soaked for 10 min each night in a 4% formalin solution, although a few patients become allergic to this. A cotton-tipped applicator dipped into liquid nitrogen is applied to the wart until a small frozen halo appears in the surrounding normal skin. Seventy per cent of renal allograft recipients will have warts 5 years after transplantation. On the first occasion it should be washed off with soap and water after 2 h but, if there has been little discomfort, this can be increased stepwise to 6 h. Treatment is best carried out weekly by a doctor or nurse, but not by the patient. Cryotherapy, electrosurgery and laser treatment are all effective treatments in the clinic. Facial common warts these are best treated with electrocautery or a hyfrecator, but also surrender to careful cryotherapy. Plane warts On the face these are best left untreated and the patient or parent can be reasonably assured that spontaneous resolution will occur. When treatment is demanded, the use of a wart paint or imiquimod cream is reasonable. Solitary, stubborn or painful warts these can be removed under local anaesthetic with a curette, although cure is not assured with this or any other method, and a scar often follows. Bleomycin can also be injected into such warts with success but this treatment should only be undertaken by a specialist. The cure rate is higher if plantar warts are pared before they are frozen, but this makes no difference to warts elsewhere. If there has been no improvement after four or five treatments there is little to be gained from further freezings. A few minutes tuition from a dermatologist will help practitioners wishing to start cryotherapy. Blisters should not be provoked intentionally, but occur from time to time, and will not alarm patients who have been forewarned. Anogenital warts Women with anogenital warts, or who are the partners of men with anogenital warts, should have their cervical cytology checked regularly as the wart virus can cause cervical cancer. Imiquimod is an immune response modifier that induces keratinocytes to produce cytokines, leading to wart regression, and may help to build cell-mediated immunity for longlasting protection. It is not universally effective and should not be given to patients with immunodeficiencies or blood dyscrasias who might not be able to resist even the attenuated organism. Varicella (chickenpox) Cause the herpes virus varicella-zoster is spread by the respiratory route; its incubation period is about 14 days. Presentation and course Slight malaise is followed by the development of papules, which turn rapidly into clear vesicles, the contents of which soon become pustular. Over the next few days the lesions crust and then clear, sometimes leaving white depressed scars. Lesions appear in crops, are often itchy, and are most profuse on the trunk and least profuse on the periphery of the limbs (centripetal). Differential diagnosis Smallpox, mainly centrifugal anyway, has been universally eradicated, and the diagnosis of chickenpox is seldom in doubt.

At any of these sites, pressures can be measured, blood samples obtained, and contrast media injected. The catheter is connected to a pressure transducer and the values obtained are compared with normal (Table 1. Blood samples from each cardiac site are analyzed for oxygen content or hemoglobin saturation to determine if a shunt is present. Normally, the oxygen saturation in each right-sided cardiac chamber is similar, but an increase in the oxygen saturation in any chamber, compared with the preceding site, may mean a left-to-right shunt at that level. Normal variations in oxygen content occur, so a slight increase may not indicate a shunt. Normally, the oxygen saturation of blood in the left atrium, the left ventricle, and the aorta should be at least 94%; if less than 94%, a right-to-left shunt is present. The pressure and oximetry data can be used to derive various measures of cardiac function. The arteriovenous oxygen difference is obtained by analyzing blood samples drawn from the arterial side of the circulation (aorta or peripheral artery) and from the venous side of the heart (usually the pulmonary artery). Cardiac output determined by the Fick principle is widely used in analyzing catheterization data and has become the standard with which other methods of determining cardiac output, such as thermodilution, are compared. Therefore, the blood flow through the lungs may differ from that through the body. Except for oxygen saturation (%), all other variables required for oxygen content calculation. Resistance is also expressed as dyne cm/s5, which can be converted from Wood units by multiplying by 80. Radio-opaque contrast material can be injected through the catheter into a cardiac chamber and serial X-ray images obtained digitally or on film (cine angiography). The imaging system can be rotated around the patient so that angulated projections can be obtained to visualize various structures better (axial angiography). Satisfactory details may be illustrated by injecting the material into the pulmonary artery and then imaging as the contrast passes through the left side of the heart (levophase). As with any procedure, cardiac catheterization is associated with complications; the benefits from cardiac catheterization must clearly outweigh the risks. The risk is higher in infants, particularly neonates, who are often critically ill and require catheterization so that a lifesaving catheter intervention or operation can be performed. Temporary or permanent occlusion of the femoral vein or entire inferior vena cava may occur, which may cause transient venous stasis and edema in the lower extremities. Seldom dangerous, the major impact is the inability to re-enter these vessels if the patient requires additional catheterization. Thrombolytic agents and heparin have been used in the acute management of patients with a pulseless extremity after catheterization. Rarely, an arteriovenous fistula develops with time between adjacent vessels used for catheter entry and requires an operation. During most cardiac catheterizations, arrhythmias of some type occur, most often premature ventricular contractions. The ionizing radiation dose received by most patients has fallen over the years because of improved image-intensifier technology, even though procedure times have lengthened for patients having interventional procedures. This area is changing rapidly, particularly with the understanding of genetic mutations in conditions that have traditionally been described only clinically. This condition can appear dramatic by echocardiography and result in left ventricular outflow obstruction. Fetal alcohol syndrome Fetal alcohol syndrome may result from even a modest consumption of alcohol during early gestation. The clinical spectrum is broad; classical features include unusual triangular facies, thin upper lip, absent philtrum, and small palpebral fissures, often with microphthalmia; hypoplastic nails; and a variety of neurodevelopmental abnormalities. The occurrence of cardiac malformations is about 3% with the usual distribution of anomalies. In these mothers, injury to the developing conduction system and, rarely, the myocardium occurs when these maternal IgG autoantibodies cross the placenta and bind to fetal cardiac tissue.

Prevention Chapter 4 W ithin the framework for strengthening early childhood mental health and social-emotional development, prevention includes screening and targeted supports. Screening provides a mechanism to identify primary care providers, especially mothers, and children at risk of or in need of social-emotional and mental health supports. Once identified, targeted supports include social and emotional supports to prevent or resolve outstanding concerns. For parents, this includes brief counseling and support for mild mental health or substance use problems. For children, prevention and early intervention strategies include explicit instruction in social skills and emotional regulation. Comprehensive treatment for parents and children with more intensive social-emotional and mental health needs is discussed in Chapter 5. Prevention Through Early Intervention With Primary Caregivers of Young Children Maternal Depression Approximately 10-20% of mothers are affected by prenatal and postpartum depression. This pyramid model conceptualizes the critical building blocks for achieving healthy mothers and healthy children. The front face of the pyramid explains the individuals and families who receive programs and services, which are divided up by the following categories: promotion, prevention, and intervention. Pregnant women with depression also are more likely to engage in risk-taking behaviors, such as substance abuse, and may decrease compliance with prenatal care. Postpartum depression negatively affects the health of the mother and can permanently impact the health and development of the infant. In order to escape depression, some may have thoughts of using violence towards themselves or their baby. Depression after childbirth impedes maternal emotional health and impairs parenting. Because mothers are emotionally disengaged, bonding and creating a positive mother-infant relationship is disturbed.

When inflammatory activity in the scalp subsides and hair regrows, nails usually revert to normal within another 6 months. It primarily affects children from 2 to 8 years of age and is more common among Japanese or children of Asian descent. These include desquamation of the palmar and plantar skin that begins with separation at the distal-free edges of the nails (Figure 8. A golden brown chromonychia of the nail plates is rarely observed within a few weeks after the onset of the illness. Some investigators believe that these conditions differ in their pathophysiology while others contend that they are the same disease on a spectrum of extent and severity. Photo-onycholysis Phototoxicity from ingestion of medications is a distinctive, frightening, and painful condition that rarely occurs in children. It is most commonly seen in teenagers being treated with doxycycline for acne (Figure 8. It has also been reported in immunosuppressed children on voriconizole12 and in one patient on griseofulvin. There may or may not be evidence of sunburn on the dorsum of the fingers and hands. Pain may be followed by subungual ecchymoses and then separation of the nail plate from the nail bed. The condition is transient and nails grow out normally once the offending agent is discontinued. It may involve all or a portion of the nail matrix, the nail bed, or the entire nail unit. When the proximal nail matrix is solely involved, the nails have the appearance of trachyonychia (Figure 8. The plates have a dull, lusterless color from small confluent pits or longitudinal striations that result in a sandpaperlike texture. As more of the nail matrix is involved, the plates become thinner and more ridged. Pterygium of the proximal nail fold is a sign of atrophy and may progress to total anonychia. Longitudinal erythronychia can be observed with distal matrix and nail bed involvement. However, if distal chipping is a problem, several coats of clear nail hardener may be applied as needed. In young children, a 6- to 12-week trial of high potency topical steroid can be tried first. Fortunately, it is non-scarring and gradually resolves along with the selflimited skin rash. There is also a high spontaneous mutation rate and mosaic or localized forms are reported. Acral involvement including nail disease may be the first manifestation during childhood. The nails display longitudinal red and white bands that extend through the nail bed from the distal matrix. The plates are thin and will frequently be fissured with "v" shaped notches at the distal-free edge (Figure 8. Greasy flat-topped warty papules are seen on the dorsum of the hands, but they become much more confluent in the seborrhea areas of the chest and back in older teens and adults.
