The goal of this study is to present the clinical and evolutive features of Pneumocystis infection (PCP) in infants admitted in our clinic. We summarise these aspects from 17 cases (10 male and 7 female infants), admitted between 1st January 2004 and 31st May 2005. PCP infection is rare. It represents 1,5/1000 children (17 cases of 11328 total patients) admitted in our hospital. The risk factors for PCP were age between 6 weeks and 6 months (average 3,38 months) low birth weight (average = 2428 grams), low weight for age, prolonged hospital admission (88,23% of the 17 infants were abandoned in nursery). Only one of them had HIV infection and none presented neoplastic disease. The most prominent clinical aspect was tachypnea (average 78 breath/minute, maximum 130). 16 (94,11%) had difficult breathing with chest in-drawing and flaring of ala nasi. 14 (82,35%) had generalised cyanosis. Only two (11,72%) infants had fever. Radiologic aspects were evocative, with diffuse pulmonary involvement in almost all cases (88,23%). 6 infants (35,29%) had pneumothorax and 2 (11,76%) presented pneumomediastinum. Positive diagnosis was made by microscopic examination of secretions from endotracheal tube aspiration (Grocott methenamine silver stain and Romanowsky stain). 14 infants were ventilated with a good outcome--12 surviving infants (85,7%). All infants had a full course of intravenous Co-trimoxazole. The deceased infants had more risk factors--congenital heart disease 1 case, severe cerebral palsy with organic epilepsy 2 cases. The apparent increase of PCP cases can be related to the number of abandoned children in Romanian pediatric hospitals and nurseries.

Recent research has highlighted the cardiovascular problems that some HIV patients have had while being treated with protease inhibitors (PIs), but it's been difficult for physicians to determine exactly which drugs are causing the most trouble. Now a new study, presented at the 45th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), held Dec. 16-19, 2005, in Washington, DC, shows that there is a significant difference in coronary risk depending on which PI a patient takes. Investigators found that patients receiving atazanavir had a significantly lower risk over a 10-year period of coronary heart disease than did patients receiving nelfinavir, and this lower risk remained statistically significant for patients who had other heart disease risk factors, including smoking, diabetes, and hypertension.

Several of the physical symptoms and illnesses related to HIV disease and its treatment--such as fatigue, weight changes, memory loss, depression, and atherosclerosis--mimic typical age-related health problems. It is estimated that at least 10% of HIV positive people in the United States are 50 years of age or older--a number that will certainly increase as people with HIV live longer thanks to effective antiretroviral therapy. For older women, sorting out the interplay between HIV, aging, and the side effects of medications can be very difficult. Many health problems are exacerbated by smoking, obesity, and poor health behaviors that can lead to an increased risk of illness or death. This article addresses two common health risks in aging women with HIV: heart disease and osteoporosis.

Testosterone treatment is controversial for men and even more so for women. Although long-term outcome data are not available, prescriptions for testosterone are becoming more common. Testosterone is used primarily to treat symptoms of sexual dysfunction in men and women and hot flashes in women. Potential benefits include improved libido, increased bone mass, and increased sense of well-being. In individuals with human immunodeficiency virus infection or other chronic diseases, testosterone has been shown to improve mood and energy levels, even in patients with normal testosterone levels. Testosterone can be administered by injection, patch, topical gel, pill, or implant. Side effects in men include polycythemia and acne. Side effects in women include acne, hepatotoxicity, and virilization and usually only occur when testosterone is used in supraphysiologic doses. Long-term studies of the effects of testosterone on prostate cancer, breast cancer, and heart disease have not been completed. Mammograms and monitoring of prostate-specific antigen, hematocrit, and lipid levels are recommended for patients taking testosterone.

Bosentan (Tracleer), an orally administered dual endothelin (ET)(A) and ET(B) receptor antagonist, is indicated in the treatment of pulmonary arterial hypertension (PAH). The efficacy of oral bosentan 125 mg twice daily in improving exercise capacity has been demonstrated in well designed trials in adult patients with idiopathic PAH or PAH associated with connective tissue disease or congenital systemic-to-pulmonary shunts, and in other trials in patients with idiopathic PAH or PAH associated with congenital heart disease or HIV infection. The beneficial effects of first-line bosentan treatment may be maintained for up to 1 year in patients with idiopathic PAH or PAH associated with connective tissue disease. Despite the potential for treatment-related teratogenicity and hepatotoxicity, long-term data indicate that bosentan is generally well tolerated at the approved dosages. Although well designed trials are required to establish the efficacy of bosentan versus or in combination with other specific PAH therapies, especially sildenafil, the convenient oral administration and lack of serious injection-related adverse effects may render bosentan preferable to other PAH therapies. Preliminary data indicate that bosentan may be effective in pediatric PAH patients, although randomized trials are required. Furthermore, bosentan may be a useful option for the prevention of digital ulcer development in patients with systemic sclerosis. Thus, in accordance with current clinical guidelines, bosentan is a convenient, effective, and generally well tolerated agent for use in the first-line treatment of class III PAH or second-line treatment of class IV PAH.

The survival of patients with HIV infection who have access to highly active antiretroviral therapy has dramatically increased. In HIV-infected persons, cardiovascular disease can be associated with HIV infection, opportunistic infections or neoplasias, use of antiretroviral drugs or treatment of opportunistic complications, mode of HIV acquisition (such as intravenous drug use), or with the classic non-HIV-related cardiovascular risk factors (such as smoking or age). Diseases of the heart associated with HIV infection or its opportunistic complications include pericarditis and myocarditis. Pericarditis may lead to pericardial effusion rarely causing tamponade. Cardiomyopathy is often clinically silent with asymptomatic left ventricular systolic dysfunction. Endocarditis is mainly the consequence of intravenous drug abuse, possibly leading to life-threatening valvular insufficiency with the need for cardiac surgery. A further serious condition associated with HIV infection is pulmonary hypertension potentially leading to right heart failure. The cardiovascular complications of HIV infection such as cardiomyopathy and pericarditis have been reduced by highly active antiretroviral therapy, but premature coronary atherosclerosis is now a growing problem because antiretroviral drugs can lead to serious metabolic disturbances resembling those in the metabolic syndrome. Lipodystrophy, a clinical syndrome of peripheral fat wasting, central adiposity, dyslipidemia, and insulin resistance, is most prevalent among patients treated with protease inhibitors. These patients should thus be screened for hyperlipidemia, hyperglycemia, and hypertension, and they may be candidates for lipid-lowering therapies. When initiating lipid-lowering therapy, interactions between statins and HIV protease inhibitors affecting cytochrome P450 function must be considered. Restenosis rate after percutaneous coronary intervention may be unexpectedly high.

A number of studies have found an association between what people see, hear and read in the mass media and their corresponding actions and beliefs. This link has been demonstrated both at the micro and at the macro levels of analysis. However, when people are asked directly about the impact of mass media they tend to deny that they are personally affected. In fact, they tend to describe themselves as critical and skeptical media consumers. The purpose of this paper is to explore this contradiction through 12 in-depth focus group discussions undertaken in Ontario, Canada in 2004. Findings from the focus group interviews confirm earlier research in that people claimed that they were not susceptible to media influence. At the same time as they said that they took information from the mass media "with a grain of salt", they articulated sophisticated and nuanced accounts of how and why they evaluated some information as good and some as bad. In general they evaluated media stories on the basis of the values of allopathic medicine and positivistic science. Moreover, in the context of the focus groups and their explicit comments on their skepticism, they discussed health information from the magazine articles that they were given to read (on either HIV/AIDS, Alzheimer's disease, or a heart disease). Possible explanations for these paradoxical findings are discussed.

Pulmonary arterial hypertension (PAH) is a rare and debilitating disease characterized by abnormal proliferation and contraction of pulmonary vascular smooth muscle cells. The resulting increase in pressure and pulmonary vascular resistance results in progressive right heart failure, low cardiac output, and ultimately death if left untreated. PAH is defined by a persistent elevation in pulmonary artery pressure with normal left-sided pressures, differentiating it from left-sided heart disease. Symptoms progress from shortness of breath and decreasing exercise tolerance to right heart failure, with peripheral edema and marked functional limitation. Exercise-induced syncope, worsening symptoms at rest, and intractable right heart failure indicate critical disease. PAH may be idiopathic with no identifiable cause or associated with collagen vascular diseases, drugs, HIV, liver disease, and/or congenital heart disease. Familial or genetically mediated PAH accounts for a small percentage of cases. Advances in the understanding of pathobiological pathways that contribute to vascular proliferation and remodeling have resulted in new therapies that improve quality of life and survival. Emerging therapies focus on the nitric oxide, prostacyclin, and endothelin pathways. Nursing interventions are critical to ensure patients' success with these expensive and complex treatments and their optimal adjustment to living with PAH.

Oxidative DNA damage is one of the most important and most studied mechanisms of disease. It has been associated with a range of terminal diseases such as cancer, heart disease, hepatitis, and HIV, as well as with a variety of everyday ailments. There are various mechanisms by which this type of DNA damage can be initiated, through radiation and chemical oxidation, among others; however, these mechanisms have yet to be fully elucidated. A HPLC-UV-EC study of the oxidation of DNA mediated by nickel(II) obtained results that show an erratic, almost oscillatory formation of 8-oxoguanine (8-oxoG) from free guanine and from guanine in DNA. Sporadic 8-oxoG concentrations were also observed when 8-oxoG alone was subjected to these conditions. A HPLC-MS/MS study showed the formation of oxidised-guanidinohydantoin (oxGH) from free guanine at pH 11, and the formation of guanidinohydantoin (GH) from DNA at pH 5.5.

Common in the medically ill, sexual dysfunction results from disruption of one or more stages of the sexual response cycle. Increased understanding of sexual pathophysiology and the psychosocial forces whereby diseases impede normal function promotes more informed treatment choices. This review focuses on the pathophysiology, impact, and treatment options of sexual dysfunction in men and women with spinal cord injuries, multiple sclerosis, dementia, hypertension, heart disease, stroke, cancer, and HIV/AIDS.
