LYON, France -- As the complexity of assisted reproduction techniques increases, so does the frequency of umbilical cord abnormalities, Belgian investigators reported here.

BALTIMORE -- About half of children who develop autism may be diagnosable by 14 months of age, researchers found in a small study that dropped the bar for early diagnosis by six months.

HOUSTON -- Standard helical PET-CT cardiac imaging produces false-positives 40% of the time, although most of the errors can be identified and corrected before inappropriate treatment.

ROCKVILLE, Md. -- Some patients may be at greater risk of lung cancer because of variations in genes involved in inflammatory responses, researchers here said.

NEW YORK -- Cardiac surgery can be performed safely in many patients with mild liver cirrhosis, and in select patients with moderate cirrhosis, according to investigators here.

WASHINGTON -- Medicare's Part B physician fee schedule will be cut 9.9%, starting next January, the government has announced, prompting anguished warnings from the AMA of decreased access to medical services for seniors.

BOSTON -- Testing for cystatin C appears to be as good as, if not better than, standard measures of kidney function to predict mortality risk in advanced chronic kidney disease, researchers found.

STANFORD, Calif. -- Compared with nifedipine (Procardia), magnesium sulfate was significantly more likely to cause serious maternal site effects when used to prevent preterm labor.

NEW YORK -- Showing evidence of a link between environmental factors and migraine, investigators here found that a higher family income may protect adolescents against migraine -- if they have no genetic predisposition to it.

Pain is recognized as a significant disability in HIV-infected persons.

Both HIV and its treatment, particularly protease inhibitors, can cause dyslipidemia similar to that seen with the metabolic syndrome. The most notable effects are elevated triglyceride levels and decreased high-density lipoprotein cholesterol levels, with or without elevated low-density lipoprotein cholesterol (LDL-C) levels.

Elevated fasting triglyceride levels and low levels of high-density lipoprotein cholesterol (HDL-C) are the hallmarks of HIV-associated dyslipidemia. Despite the perception of many HIV-infected patients and their clinicians, low-density lipoprotein cholesterol (LDL-C) levels among persons infected with HIV-even those receiving antiretroviral therapy––tend to be lower than those in uninfected controls.1,2 During antiretroviral therapy, increases in all lipid parameters are common; however, it is dramatic rises in triglyceride levels that for a number of reasons can be of the most concern.

One of the 2 feature articles this month in The Aids Reader is a review of the literature on the management of dyslipidemia. In this article, Dr Craig E. Metroka of Columbia University and colleagues focus on the use of fish oil to reduce elevated triglyceride levels, an independent risk factor for cardiovascular disease and a hallmark of antiretroviral-related dyslipidemia.

For many of us, the term "prejudice" translates into racism and then into the range of negative, stereotyped assumptions about others based on no more than externally observable features such as skin color or eye shape. We further translate this into discrimination and the full negative history of treating those whom we observe to be racially different.

AIDS Seen as New Threat to African Democracy A new study suggests that HIV/AIDS is hitting elected officials hard in southern Africa, thus posing a new threat to democracy and governance (Felix B. Reuters. June 4, 2007). The report was released in advance of South Africa's biannual AIDS conference in Durban.

In a midsummer issue of the Journal of Infectious Diseases, Dr Anthony Fauci1––who is as close as the United States comes to a tsar of AIDS medicine––describes 7 HIV-infected persons who had received protease inhibitor (PI)-based antiretroviral therapy for an average of 40.4 months (range, 31.1 to 54 months).

abstract: Tuberculous pericarditis, while relatively rare in the United States, is an important cause of pericardial disease in countries where tuberculosis is prevalent. Patients are most likely to present with chronic disease--effusive and/or constrictive. Those with effusive pericarditis often present with tamponade. Patients with constrictive pericarditis exhibit features of systemic and pulmonary venous congestion. An elevated level of adenosine deaminase in pericardial fluid is a good marker for tuberculosis. The presence of granulomas or case-ation necrosis in pericardial tissue confirms the diagnosis. If treatment of effusive tuberculous pericarditis is delayed, constrictive or effusive-constrictive disease usually develops, resulting in a high mortality risk. In addition to a standard antituberculosis regimen, treatment of tuberculous pericarditis may include adjuvant therapy with corticosteroids, pericardiocentesis, and/or pericardiectomy.

The effectiveness of corticosteroids in the prevention of postextubation laryngeal edema is controversial, but a recent study conducted in France indicates that the administration of methylprednisolone before a planned extubation does, in fact, reduce the incidence of laryngeal edema and reintubation.
