A case of Rhodococcus equi brain abscess

We treated a patient with acquired immunodeficiency syndrome for a brain abscess caused by Rhodococcus equi, an actinomycete that usually infects the lung in immunosuppressed hosts. Rhodococcus equi brain abscess is an extremely rare lesion that has never been reported in a patient with acquired immunodeficiency syndrome. The infection was cured by lengthy therapy with multiple antibiotics after aspiration of the lesion to identify the infective organism and determine its sensitivity to antibiotics.     

Breast cancer and HIV: what do we know?

The present acquired human immunodeficiency syndrome-defining neoplasms are Kaposi's sarcoma, non-Hodgkins lymphoma, and cervical cancer. However, other malignancies have recently been associated with human immunodeficiency virus (HIV) infection. Is there also a link between breast cancer and HIV infection? Breast cancer seems to be more aggressive in the setting of immunocompromise by HIV infection, as demonstrated by the clinical course of two patients recently treated at this institution and review of the available literature. As the acquired human immunodeficiency syndrome epidemic affects increasing numbers of women and survival improves, surgeons will be frequently called on to diagnose and treat breast cancer in the HIV+ patient.     

Three-chamber priapism in a patient with primary epithelioid hemangioendothelioma of penis

The incidence of tuberculosis in the United States is on the rise, in part, because of its association with acquired immunodeficiency syndrome. Genitourinary tuberculosis remains one of the most common forms of secondary or extrapulmonary disease. We present an unusual case of tuberculous epididymitis with extensive retroperitoneal and mediastinal spread. The possible routes of dissemination, as well as the efficacy of antimycobacterial therapy in the management of tuberculous epididymitis, are discussed and the relevant literature is reviewed.     

Pathology of the breast associated with HIV/AIDS

Breast pathology that is characteristic of patients infected with human immunodeficiency virus (HIV) has not been addressed in the literature. HIV may directly and indirectly affect the glandular, mesenchymal, and intramammary lymphoid tissue in seropositive patients. Likely infections in this setting include tuberculous mastitis and pyogenic abscesses that may lead to fatal septicemia. Benign stromal changes include gynecomastia, adipose tissue deposition as part of the fat maldistribution syndrome, and pseudoangiomatous stromal hyperplasia. Breast carcinoma in HIV-infected patients occurs at a relatively early age, with increased bilateral disease, unusual histology, and early metastatic spread with a poor outcome. However, the link between breast cancer and HIV remains controversial. Kaposi's sarcoma and non-Hodgkin's lymphoma may also be localized to the breast in patients with acquired immunodeficiency syndrome (AIDS). This article reviews benign and malignant breast diseases that are likely to be encountered in patients with HIV/AIDS.     

Testicular carcinoma in patients positive and at risk for human immunodeficiency virus

Patients with the acquired immunodeficiency syndrome are at increased risk for certain malignancies. Because acquired immunodeficiency syndrome and testicular cancer affect primarily young men, the potential complications that acquired immunodeficiency syndrome might impose raise significant concern. To address this question we performed a retrospective review of all cases of testicular cancer during an 11-year period. Of 140 patients 6 had human immunodeficiency virus infection and 7 were from human immunodeficiency virus risk groups. All cases were either stage I or II disease with seminoma in 8, teratocarcinoma in 3, embryonal cell carcinoma in 1 and teratoma in 1. The clinical presentations of these patients were comparable to those of patients without human immunodeficiency virus risk factors. The majority of the patients received standard therapy, including orchiectomy followed by lymphadenectomy, radiation therapy or chemotherapy depending on stage and pathological subtype. Patients tolerated therapy well with only 1 course of radiation therapy complicated by Pneumocystis carinii pneumonia. All patients achieved complete remission and none died of testicular cancer. Since treatment of these patients may worsen the immunosuppression, surveillance is recommended after orchiectomy for acquired immunodeficiency syndrome patients with stage I disease. However, the majority of patients with human immunodeficiency virus infection should receive standard therapy.     

Renal aspects of therapy for human immunodeficiency virus and associated opportunistic infections

Patients with human immunodeficiency virus infection and the acquired immunodeficiency syndrome are often treated with a variety of potentially nephrotoxic drugs. This review summarizes the renal, fluid, and electrolyte complications of drugs used to treat human immunodeficiency virus and associated opportunistic infections. The pharmacokinetics of the drugs are also briefly reviewed, and dosing guidelines for the use of these drugs in patients who have renal insufficiency or who are receiving dialysis are provided.     

Human immunodeficiency virus testing: update.

Human immunodeficiency virus (HIV) types 1 and 2 have been associated with the acquired immunodeficiency syndrome (AIDS). The detection of HIV infections is based on the screening of serum samples for the presence of antibodies to HIV proteins. Serum samples that test positive on screening must be assayed by a confirmatory test to provide a definitive report on the presence of HIV infection. This article reviews the currently available screening and confirmatory testing procedures and their limitations.     

Testicular seminoma associated with the acquired immunodeficiency syndrome and acquired immunodeficiency syndrome related complex: 2 case reports

Two homosexual men positive for human immunodeficiency virus with evidence of acquired cellular immunodeficiency were diagnosed recently to have seminoma of the testis. One man has the acquired immunodeficiency syndrome with lymphopenia, a low CD4:CD8 ratio, condylomata accuminata, pneumocystis carinii and cerebral toxoplasmosis, and 1 has an acquired immunodeficiency syndrome related complex with generalized lymphadenopathy showing follicular hyperplasia on biopsy, recurrent Herpes simplex infections and lymphopenia but a supranormal CD4:CD8 ratio. Neither patient has a known risk factor for testicular seminoma. Our report provides supportive evidence for the presence of an increased risk of seminoma of the testis in patients with acquired immunodeficiency syndrome and acquired immunodeficiency syndrome related complex.     

Surgical management of pneumothorax in patients with acquired immunodeficiency syndrome

Pneumocystis carinii pneumonia in a patient with acquired immunodeficiency syndrome may cause severe alveolar damage, resulting in pneumothoraces that are often bilateral, recurrent, and refractory to accepted methods of treatment. The clinical features, management, and follow-up results were assessed in 22 consecutive patients who presented with a pneumothorax and acquired immunodeficiency syndrome. Seventeen patients died within the time frame of this study. Their average survival time was 147 days. Five surviving patients have lived an average of 366 days. We proposed an algorithm to assist in the management of pneumothoraces in these patients. We concluded that pneumothorax in patients with acquired immunodeficiency syndrome is prognostic of short-term survival. The results in the treatment of pneumothorax in the patient with acquired immunodeficiency syndrome are related to the pathologic lesions of the lung that are associated with Pneumocystis pneumonia and not to the surgical treatment that is employed.     

Determination of acquired immunodeficiency syndrome (AIDS) after renal transplantation

Diagnosing the acquired immunodeficiency syndrome (AIDS) in transplant recipients can be difficult due to the patient's medication-induced immunosuppressed state. We report two renal allograft recipients who acquired HIV infection at the time of transplantation and later went on to develop multiple opportunistic infections. Careful documentation of HIV antibody status of the donor and recipient, when available, the nature of immunosuppressive therapy used, the type of infections and their timing after transplantation, as well as the patient's absolute T4 lymphocyte count, T cell ratio, and B cell humoral response to infection were used as factors to distinguish between infection related to immunosuppressive therapy and that seen in HIV-induced immunodeficiency. Reduction in immunosuppressive therapy because of the HIV-related immunodeficiency state did not result in allograft rejection. Both patients died of their multiple infections. The determination of AIDS in the transplant recipient has both therapeutic and prognostic significance. This diagnosis should be considered when transplant patients develop unusual infections in relationship to their posttransplant course.     

Bordetella bronchiseptica pneumonia in a patient with AIDS.

Bordetella bronchiseptica is recognised as a respiratory tract pathogen in many mammalian species, but has rarely been implicated in human infection. A case is reported of pneumonia caused by B bronchiseptica in a patient suffering from acquired immunodeficiency syndrome (AIDS).     

Tuberculous abscess of the cerebellum. Apropos of a case

A 22-year-old Asian man developed intracranial hypertension with a 38 degrees C fever. Two months earlier, he had undergone surgery and medical treatment for tuberculous otomastoiditis and pulmonary tuberculosis. The CT scan revealed multiple tuberculous abscesses of the cerebellum. Histological, microbiological and biological proof of diagnosis was obtained. We advocate surgical treatment of intracranial tuberculous abscesses associated with antituberculosis chemotherapy for 18 months. The earlier the treatment, the better the prognosis. This pathology must be kept in mind when treating patients from countries with a high endemic rate of tuberculosis and suffering from immunodeficiency syndrome.     

Pulmonary pseudotumour due to Corynebacterium equi in a patient with the acquired immunodeficiency syndrome.

A case of inflammatory pseudotumour of the lung in a patient with the acquired immunodeficiency syndrome due to infection by Corynebacterium equi is described.     

Prevention of lung infections associated with human immunodeficiency virus infection.

Current evidence indicates that the length of survival for patients with the acquired immunodeficiency syndrome (AIDS) is increasing, thereby affording a greater opportunity for strategies designed to prevent the infectious diseases that mark the syndrome. Because these infections may occur at different stages of immunosuppression caused by the human immunodeficiency virus (HIV), effective application of preventive measures depends not only on detection of HIV infection but also on the use of staging indicators. The diseases that serve to define AIDS, such as Pneumocystis carinii pneumonia, tend to occur late in the course of HIV infection and often when the T helper lymphocyte (CD4+ cells) count is less than 0.2 x 10(9)/l. Other infections, such as tuberculosis and pyogenic bacterial pneumonia, may develop at any point after HIV infection has occurred. Given this relation between the degree of immunosuppression and the occurrence of particular pulmonary infections, different preventive interventions should be applied at different times. It is now known that the incidence of several of the pulmonary infections that are common in patients with HIV infection can be reduced by prophylactic measures. Pneumocystis pneumonia is decreased in frequency by any one of several prophylactic agents, the best established being pentamidine administered as an inhaled aerosol. The role of isoniazid in the chemoprophylaxis of tuberculosis in patients not infected with HIV is well established. Although there is little evidence of benefit so far from isoniazid in HIV infected patients with a positive tuberculin skin test response, it is logical to assume that there could be some effect. The use of pneumococcal polysaccharide vaccine may also be of some benefit in reducing the frequency of pneumococcal pneumonia in patients with AIDS. In addition to these specific measures, the antiretroviral agent zidovudine decreases both the frequency and the severity of opportunist infections, at least during the first few months of treatment. A comprehensive strategy for prevention of HIV associated lung infection first requires detection of HIV seropositivity, staging the immunosuppression by the CD4+ cell count, and determining whether tuberculous infection is present by a tuberculin skin test. All seropositive individuals should be given pneumococcal vaccine and those with evidence of tuberculosis infection should be treated with isoniazid for one year. Zidovudine should probably be started when CD4+ cell counts are in the range 0.4-0.5 x 10(9)/l and prophylaxis against pneumocystis infection when CD4+ cell counts are in the range 0.2-0.3 x 10(9)/l.     

Liver transplantation for patients with human immunodeficiency virus and hepatitis C virus coinfection with special reference to hemophiliac recipients in Japan

Liver transplantation for patients with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) remains challenging. The advent of highly active antiretroviral therapy (HAART) for HIV has reduced mortality from opportunistic infection related to acquired immunodeficiency syndrome dramatically, while about 50% of patients die of end-stage liver cirrhosis resulting from HCV. In Japan, liver cirrhosis frequently develops after HCV-HIV coinfection resulting from previously transfused infected blood products for hemophilia. The problems of liver transplantation for those patients arise from the need to control calcineurin inhibitor with HAART drugs, the difficulty of using interferon after liver transplantation with HAART, and the need to control intraoperative coagulopathy associated with hemophilia. We review published reports of liver transplantation for these patients in the updated world literature.     

Human Immunodeficiency Disease: How Should It Affect Surgical Decision Making?

Background  The ever-increasing prevalence of human immunodeficiency virus (HIV) infection and the continued improvement in clinical management has increased the likelihood of surgery being performed on patients with this infection. The aim of the review was to assess current literature on the influence of HIV status on surgical decision-making. Methods  A literature review was performed using MEDLINE articles addressing “human immunodeficiency virus,” “HIV,” “acquired immunodeficiency syndrome,” “AIDS,” “HIV and surgery.” We also manually searched relevant surgical journals and completed the bibliographic compilation by collecting cross references from published papers. Results  Results of surgery between noninfected and HIV-infected individuals and between HIV-infected and acquired immunodeficiency syndrome (AIDS) patients are variable in terms of morbidity, mortality, and hospital stay. The risk of major surgery is not unlike that for other immunocompromised or malnourished patients. The multiple co-morbidities associated with HIV infection and the availability of highly active antiretroviral therapy must be considered when assessing and optimizing the patient for surgery. The clinical stage of the patient’s disease should be evaluated with a focus on the overall organ system function. For patients with advanced HIV disease, palliative surgery offers relief of acute problems with improvement in the quality of life. When indicated, diagnostic surgery assists with further decision-making in the medical management of these patients and hence should not be withheld. Conclusion  HIV infection should not be considered a significant independent factor for major surgical procedures. Appropriate surgery should be offered as in normal surgical patients without fear of an unfavorable outcome.     

Perforation of the terminal ileum with cytomegalovirus vasculitis and Kaposi's sarcoma in a patient with acquired immunodeficiency syndrome

This case report documents a perforation of the terminal ileum in a 40-year-old white male homosexual with the acquired immunodeficiency syndrome. The perforation occurred at a site that had severe cytomegalovirus infection and was in close proximity to multiple nodules of Kaposi's sarcoma. The ileum showed multiple deep ulcers with large numbers of cytomegalovirus inclusions and vasculitis with infected endothelial cells, small-vessel thrombosis, focal disruption, and hemorrhage. We review the evidence that cytomegalovirus infection--and not Kaposi's sarcoma--was responsible for this perforation and, in light of the new medical therapy for such infections, should be regarded as an important cause of gastrointestinal perforation in patients with the acquired immunodeficiency syndrome.     

Major salivary gland lymphoepithelial lesions and the acquired immunodeficiency syndrome

Presently, there is no consensus regarding the most appropriate diagnostic and therapeutic approach to patients with human immunodeficiency virus (HIV)-associated lymphoepithelial lesions of the major salivary glands. A retrospective review of 60 consecutive patients with lymphoepithelial lesions is presented. Thirty-eight cases were associated with HIV infection. Lesions associated with HIV infection were usually bilateral, multiple, cystic, and associated with lymphadenopathy. In contrast, in those cases without HIV infection, the lesions tended to be solitary and solid. In the HIV-infected group, treatment included surgery, radiotherapy, zidovudine (AZT), and/or cyst aspiration. All therapeutic regimens, other than aspiration alone, were found to be effective. Eighteen of the patients with HIV infection developed the acquired immunodeficiency syndrome (AIDS) during the study period. Surgical treatment is probably not necessary in the majority of HIV-associated cases. Depending upon individual circumstances, treatment with AZT or low-dose radiotherapy is recommended. A diagnostic and therapeutic algorithm is presented as a guide to the management of future cases.     

AIDS, surgery, and the Americans With Disabilities Act

The acquired immunodeficiency syndrome and human immunodeficiency virus have had a major impact on the practice of medicine in the past 2 decades. Medical professionals are once again faced with a lethal contagious disease that has been transmitted in the health care setting to both patients and providers. Because of the stigma and fear associated with the infection, civil rights legislation, such as the Americans With Disabilities Act, has been used to protect infected individuals from inappropriate discrimination based on unwarranted fears and public hysteria. Various courts, with the backing of organized medicine and the public health authorities, have made it clear that it is illegal for a physician to refuse to treat a patient based on the patient's seropositivity. Unfortunately, various courts, with the backing of the American Medical Association and the Centers for Disease Control and Prevention, have made it clear that infected physicians are not necessarily afforded equal protection under the civil rights statutes.
