[Candida laryngitis and HIV infection: description of 4 cases].

Candidiasic laryngitis is a very rare Candida spp infection of mucosa, appearing typically in immunosuppressed patients, mainly in patients with neoplasia, and, recently, in patients with Human Immunodeficiency Virus (VIH) infection. We present four cases of candidiasic laryngitis and HIV infection, as well as the clinical description and evolution of said cases after treatment with fluconazole. We review, as well, the cases published on the scientific literature. We maintain that in each HIV infected patient, with or without oral candidiasis, who shows dysphonia, candidiasic laryngitis should be ruled out.

[Fluconazole treatment of cryptococcal meningitis associated with HIV infection. Presentation of 4 cases].

We present four cases of C. neoformans meningitis (CNM) in patients with Human Immunodeficiency Virus (HIV) infection treated with fluconazole p.o. at an initial dose of 400 mg followed by 200 mg/day during a follow up period ranging from 3 to 12 months, and who presented an excellent clinical evolution. When comparing them to our previous cases who were treated with Amphotericin-B in combination with 5-fluorocytosine, a decrease in mean hospital stay (p less than 0.001) and a smaller incidence of secondary effects were observed. Treatment with fluconazole seems to be an effective alternative in treatment of CNM. Future greater studies are needed to confirm this findings.

[Pneumocystis carinii pneumonia in AIDS and prolonged fever].

Pneumonia by Pneumocystis carinii (NPC) presents a high incidence in the evolution of patients infected by the human immunodeficiency virus (HIV). Common clinical signs include fever, dry cough and dyspnea, in the presence of pulmonar interstitial affection with several degrees of hypoxemia. One hundred and sixteen patients with NPC and infection by HIV were diagnosed between December 1986 and January 1990. Criteria of persistent fever was established in 10 of them (8.7%), with normal thoracic radiography at the time of hospitalization. NPC in the adquired immunodeficiency syndrome (SIDA) may develop' with persistent fever, joining the large relation of entities manifesting in this way.

[A serum immunoglobulin study in patients with tuberculosis and human immunodeficiency virus infection].

We present the immunoglobulin spectrum in a series of 156 HIV-infected patients who were affected of tuberculosis (TB) of different localization. Sixty-seven patients had lung TB, in 13 cases lung TB and an opportunistic infection were diagnosed simultaneously and in 76 cases TB was localized outside the lung. The cases were compared to 62 HIV-infected patients classified in stage 11 (CDC 1986) and to 85 cases of HIV-infected patients who suffered carinii pneumonia (PCP). The most outstanding differences were established between IgA of patients with lung TB and group PCP (p less than 0.001). IgG showed significant differences between lung TB patients and the PCP group (p less than 0.001).

Running energetics in the pronghorn antelope.

The pronghorn antelope (Antilocapra americana) has an alleged top speed of 100 km h-1, second only to the cheetah (Acionyx jubatus) among land vertebrates, a possible response to predation in the exposed habitat of the North American prairie. Unlike cheetahs, however, pronghorn antelope are distance runners rather than sprinters, and can run 11 km in 10 min, an average speed of 65 km h-1. We measured maximum oxygen uptake in pronghorn antelope to distinguish between two potential explanations for this ability: either they have evolved a uniquely high muscular efficiency (low cost of transport) or they can supply oxygen to the muscles at unusually high levels. Because the cost of transport (energy per unit distance covered per unit body mass) varies as a predictable function of body mass among terrestrial vertebrates, we can calculate the predicted cost to maintain speeds of 65 and 100 km h-1 in an average 32-kg animal. The resulting range of predicted values, 3.2-5.1 ml O2 kg-1 s-1, far surpasses the predicted maximum aerobic capacity of a 32-kg mammal (1.5 ml O2 kg-1 s-1). We conclude that their performance is achieved by an extraordinary capacity to consume and process enough oxygen to support a predicted running speed greater than 20 ms-1 (70 km h-1), attained without unique respiratory-system structures.

Race or class or race and class: growing mortality differentials in the United States.

Recent statistics on increasing differences in mortality rates between blacks and whites in the United States are causing a great deal of concern. The reduction of this gap is an important national goal. Yet mortality differentials cannot be explained solely by race. We must also look at class, as do all Western nations other than the United States, when compiling health statistics. In the United States, how people live, get sick, and die depends not only on their race, sex, and age, but also on their class, whether measured by level of education, income, or occupation. Class differentials in mortality and morbidity are greater than race differentials. By focusing our attention on race differentials alone, we will not be able to understand why the health indicators of minorities in the United States are deteriorating.

An analysis of the American Medical Association's recommendations for change in the medical care sector of the United States.

In several recent publications, the American Medical Association has provided explanations of the current crisis in the medical sector of the United States. This article presents empirical information that questions the basic assumptions behind the AMA's explanations of the U.S. realities and the AMA's recommendations on how to solve the current crisis. The author also critically reviews some of the major proposals--such as employer mandated coverage--that are being put forward by several forces in the United States, including the AMA, for resolving the twin problems of high costs and limited health benefits coverage for the U.S. population. The political context in which the AMA's calls for reforms are being made is also discussed.

Production and the welfare state: the political context of reforms.

This article is an analysis of the political context of reforms in the production process and in the welfare state. The theories of legitimation and Fordism are criticized for considering the capitalist class the main force behind the reforms. The working class and the process of class struggle are primarily responsible for changes in production and for the establishment of the welfare state. The author then shows that the changes in production and in the state that occurred after World War II were a response to political events triggered by labor's rebellions and capital's need to respond to those rebellions. Post-Fordism and the political practice that derives from it are criticized for their hasty dismissal of class and class practices by the dominated forces in society. The article ends by offering an alternative strategy for change.

The relevance of the U.S. experience to the reforms in the British National Health Service: the case of General Practitioner Fund Holding.

This article presents a discussion of the relevance of the U.S. experience in general, and health maintenance organizations in particular, to the reforms advocated by the current Conservative government in the general practitioner services of the British National Health Service. The author analyzes empirical information relevant to the assumptions made by the Conservative reformers that (1) the HMO type of practice is better able to respond to people's needs than are current general practitioner arrangements; (2) entrepreneurship in medicine is good for patients; (3) market-based primary care is more efficient than the nonmarket system in the United Kingdom; and (4) the expansion and strengthening of the private sector is an efficient and equitable means of encouraging competition and raising revenues. All of these assumptions are questioned.

The West German health care system: a critique.

Several leading health policy staff of the AFL-CIO and major unions met with the Board of Physicians for a National Health Program (PNHP) in May 1990. They described the active discussions currently ongoing within the AFL-CIO Health Care Committee, which is composed of 14 international union presidents and sets AFL-CIO policy on health care issues. Some union presidents reportedly favored a single-payer, Canadian-style approach, while others apparently preferred a proposal modeled after the West German system, which preserves a major role for insurance companies. The PNHP Board was emphatic in its preference for the single-payer approach. Board member Dr. Vicente Navarro wrote the following letter to the union presidents on the AFL-CIO Health Care Committee detailing his critique of the West German approach.

[Austrian's syndrome and infection with human immunodeficiency virus].

A case of a patient diagnosed of Austrian' syndrome associated to HIV infection is presented. Our aim is to highlight the frequent but not enough described association to pneumonia, endocarditis and meningitis caused by Streptococcus pneumonia to increased its knowledge and permit a correct and early treatment, improving the bad prognosis of this association.

[Meningitis caused by Candida albicans in a male patient infected by HIV and failure of treatment with amphotericin B].

We report a case of Candida albicans meningitis in a male with human immunodeficiency virus (HIV) infection. This finding has seldom been reported, both in this group of patients and in those with other causes of immunosuppression or other underlying diseases. We discuss the clinical presentation and the features of cerebrospinal fluid, which showed only a mild inflammatory reaction as found in other fungal meningitis (basically cryptococcal) in AIDS patients. Finally, we emphasize the ineffectiveness of amphotericin therapy to achieve a complete microbiological cure and to prevent the relapse of meningitis in this patient. We also stress the need to make an early diagnosis in cases of fungal meningitis in patients with VIH infection, so that appropriate therapy is begun as soon as possible.

[Pulmonary tuberculosis with normal chest radiography and infection by human immunodeficiency virus].

We report 16 cases of pulmonary tuberculosis with normal chest x-ray film associated with infection by the human immunodeficiency virus (HIV). These patients belong to a sample of 125 cases of tuberculosis and HIV infection observed during the same study period. The clinical features and the diagnostic methods are described. The unusual character of the finding and its relevance are discussed, as the presentation of pulmonary tuberculosis with normal chest x-ray film was relatively common in patients with HIV infection (12.8%) in our series. This possibility should be considered in the whole population of patients with HIV infection.
