However, long-term effects of at2-receptor stimulation that involve cellular growth and repair are relatively unknown. While the pharmacologic differences between arbs and ace-is are clear, the therapeutic relevance resulting from these differences remains ambiguous. Previously, the clinical benefits of arbs were considered less robust as compared to ace-is, but the ongoing telmisartan alone and in combination with ramipril global end-point trial (ontarget) has demonstrated that in high-risk patients, telmisartan is noninferior to ramipril for the reduction of death from cardiovascular causes, mi, stroke, or hospitalization for hf. 38 this study also demonstrated that an ace-i in combination with an arb reduces proteinuria to a greater extent than either agent as monotherapy but increases the composite of dialysis, doubling of serum creatinine, and death. 39 although better tolerated than ace-is, arbs have not been shown to demonstrate superiority of outcomes relative to ace-is. At this point, arbs have emerged as an effective class of antihypertensives whose low incidence of side effects and demonstrated clinical role in patients with specific comorbidities have afforded them an attractive position in the antihypertensive armamentarium. However, as with ace-is, patients may develop angioedema and, although estimates of cross-reactivity are reportedly low,40 one should always exercise caution when considering the use of an arb in a patient with a known history of angioedema to an ace-i. Like ace-is, the antihypertensive effectiveness of arbs is greatly enhanced by combining them with diuretics, but combining an ace-i with an arb for treating hypertension should almost always be avoided. Furthermore, arbs have proven their value as well-tolerated alternatives to ace-is for patients with ckd, dm, and prior mi (table 5–7). In select situations, the addition of arbs to ace-is for patients with hf has demonstrated additional incremental benefits and may be considered if aldosterone antagonists are not indicated or tolerated. 40 arbs may also be considered as first line therapy when ace-is are not tolerated. 40 renin inhibitors aliskiren is the first agent in the newest class of antihypertensive agents. Although similar to ace-is and arbs in that it acts within the raas, it is unique in that it directly blocks renin, thereby reducing pra and subsequently at1 and at2 with a resultant reduction in bp. This disruption of the negative feedback loop results in a compensatory increase in pro-renin and renin levels, the significance of which is not well established. Aliskiren has been shown to be well tolerated and effective in reducing bp when used as monotherapy and in combination with other antihypertensive agents, including thiazide diuretics, arbs, and ccbs. 6 however, long-term clinical trials evaluating efficacy and safety have not been completed, and thus the effects of aliskiren on morbidity and mortality are as yet unknown. Additionally, the aliskiren trial in type 2 diabetes using cardio-renal end points (altitude), which compared ace-i or arb monotherapy to that in combination with alkiskiren, was stopped prematurely as the combination therapy did not reduce cardiovascular end points.

If the mother can be identified as having recurrent infection, the resultant neonatal infection rate is low, and parents should be instructed to consult their pediatrician if a rash or other clinical changes (lethargy, tachypnea, poor feeding) develop. Weekly pediatric follow-up during the first month is recommended. Infants with a positive culture from any site or the evolution of clinical symptomatology should immediately have cultures repeated and antiviral therapy started. Before starting acyclovir therapy, the infant should have conjunctival, nasopharyngeal swabs for dfa and culture, urine for culture, and a csf evaluation for pleocytosis and hsv dna pcr. Evidence of dissemination should be evaluated with hepatic transaminases and a chest radiograph if respiratory symptoms develop. 4. Postnatal strategies. Infants and mothers with hsv lesions should be in contact isolation. Careful hand washing and preventing the infant from having direct contact with lesions should be emphasized. Breastfeeding should be avoided if there are breast lesions, and women with oral hsv should wear a mask while breastfeeding. Hospital personnel with orolabial hsv infection represent a low risk to the newborn, although the use of face masks should be recommended if active lesions are present. Of course, hand washing or use of gloves should again be emphasized. The exception to these guidelines is nursery personnel with herpetic whitlows. Because they have a high risk of viral shedding, and as transmission can occur despite the use of gloves, these individuals should not care for newborns. Iv. Parvovirus {congenital). Parvoviruses are small, unenveloped singlestranded dna viruses. Humans are the only known host. The cellular receptor for parvovirus b19 is the p blood group antigen, which is found on erythrocytes, erythroblasts, megakaryocytes, endothelial cells, placenta, and fetal liver and heart cells. This tissue specificity correlates with sites of clinical abnormalities (which are usually anemia with or without thrombocytopenia and sometimes fetal myocarditis). Lack of the p antigen is extremely rare, but these persons are resistant to infection with parvovtrus.

They may be prescribed prophylactically with high-d2-binding agents or in patients at risk for eps or for treatment of eps. Β-blockers (eg, propranolol 30–120 mg/day) are sometimes effective for patients who develop akathisia. In some situations, such as on an inpatient unit, the concomitant use of benzodiazepines (eg, lorazepam 1–3 mg/day) with the sgas may be necessary for agitation or insomnia. Antidepressants may be useful for patients with schizophrenia who have depressive symptoms. Because suicide and depression are linked, aggressive treatment is necessary when depression is present. The selective serotonin reuptake inhibitors (ssris) are the preferred agents, but they may inhibit the cyp450 enzymes, thus raising plasma concentrations of clozapine, olanzapine, and haloperidol. Mood stabilizers, such as lithium and the anticonvulsants, have long been used adjunctively with the antipsychotics to treat the affective component of schizoaffective disorder. Approximately 30% of treatment-resistant patients given clozapine do not respond, and another 30% have only a partial response.
