Gallium imaging is increasingly being used for the early detection of complications in patients with AIDS. A 26-year-old homosexual man who was HIV antibody positive underwent gallium imaging for investigation of possible Pneumocystis carinii pneumonia. Widespread cutaneous focal uptake was seen, which was subsequently shown to be due to mycobacterium avium-intracellulare (MAI) septicemia. This case demonstrates the importance of whole body imaging rather than imaging target areas only, the utility of gallium imaging in aiding the early detection of clinically unsuspected disease, and shows a new pattern of gallium uptake in disseminated MAI infection.

Between January 1985 and March 1986, five cases of listeriosis were reported in Los Angeles County in patients with the acquired immunodeficiency syndrome (AIDS). All patients were homosexual men with no other risk factors for AIDS. Two patients had sepsis only, two patients had sepsis and meningitis, and one patient had sepsis and signs of meningitis. Sixty percent of the cases (three patients) had a prior or concurrent gastrointestinal illness. Eighty percent of the cases (four patients) also had no prior history of antibiotic administration. Both of these findings may have predisposed these AIDS patients to be at increased risk for listeriosis. Although listeriosis is an infrequent illness in AIDS patients, people with AIDS or human immunodeficiency virus infection should probably refrain from ingesting food items associated with listeriosis. These food items include improperly pasteurized dairy products, and raw fruits and vegetables not properly washed.

56 cases of pregnant women with a positive HIV serology were reported in 20 months at the Maternity of the Nice Hospital Center. In 10 cases, there were clinical signs of the disease (9 ARC-Syndrome, one case of AIDS). The predisposing factor was most of the time drug addiction, 53 cases (94.5%) and one case occurred after a blood transfusion. In the majority of the cases (52%) the pregnancy was pursued because of the late term or the patient's decision. A therapeutic abortion was performed in 12 instances (25%) and an interruption before 12 weeks of amenorrhea in 15 cases. 24 women delivered. The obstetrical complications were frequent with especially a fetal death in utero, five premature deliveries and fifteen hypotrophies. A severe infectious complication (septicemia, pneumopathy secondary to Pneumocystis carinii) was observed in 9 cases, a marked thrombopenia causing profuse post-partum haemorrhages in one case. Finally, one woman died 35 days after delivery. The study of the consequences on the child is incomplete because of insufficient follow-up: all children were sero-positive at birth and among thirteen children aged between 12 to 20 months, there were one death, one AIDS syndrome, 4 ARC-syndrome, 4 sero-positive and 3 sero-negative. The notion of HIV sero-positivity in a pregnant woman presents serious problems for the obstetrician. Decompensation of the disease during the pregnancy is uncertain but it is now confirmed that the child is affected, and this is a well established fact. These important consequences lead to propose, at this time a therapeutic interruption of pregnancy when possible, depending on the term, and when accepted by the patient.

AIDS dementia complex (ADC) is a complex, progressive neuropsychiatric syndrome seen in 60-70% of the patients with AIDS. The structural and functional changes associated with ADC may be the result of a variety of indirect mechanisms mediated via activated brain cells or/and virus that produce neurotoxins including N-methyl-D-aspartate receptor agonist (eg, quinolinic acid, glutamate), cytokines, gp 120 and nitric oxide. The level of the neurotoxin and kynurenine pathway metabolite, quinolinic acid, is increased in the brain and CSF of HIV-1-infected patients, and is correlated with quantitative measures of neurologic impairment. Importantly, increased CSF and brain levels of QUIN also occur in other inflammatory neurologic diseases (bacterial, viral, fungal and parasitic infections, meningitis, autoimmune diseases and septicemia), independent of HIV-1 infection. Therefore, QUIN and other neuroactive kynurenine pathway metabolites may be final common mediators of neurologic dysfunction in a broad spectrum of inflammatory neurologic diseases. Conversion of L-tryptophan to QUIN has also been demonstrated in vitro in both brain tissue following macrophage infiltration, and in macrophages stimulated by interferon-gamma or HIV infection. Macrophages in vitro have a high capacity to synthesize QUIN following exposure to interferon-gamma, tumor necrosis factor-alpha, IL-1 beta and IL-6, compared to cells derived from other tissues. Notably, the concentrations achieved in the macrophage incubates exceeded the levels found in the CNS of HIV-1-infected patients, and exceeded the concentrations shown to be neurotoxic in vitro. We hypothesize that increased kynurenine pathway metabolism following inflammation reflects the presence of macrophages and other reactive cell populations at the site of brain infection. Strategies to attenuate the neurotoxic effects of kynurenines, such as inhibitors of kynurenine pathway metabolism and cytokine antibodies may offer new approaches to therapy.

The infection rate for any surgical prosthesis insertion should be less than 1% in the first postoperative year. If infection occurs the patients will lose their new found mobility, lose their independence, be hospitalized with sepsis, both local and systemic, and perhaps die. Preoperative and intraoperative measures to prevent infection are well established in orthopaedic surgery but less scientifically applied in peripheral vascular surgery. In both specialties the problem of late infection has promoted research on the protection of the peri-prosthetic environment against both bacteria and biofilm. In orthopaedics, the incorporation of various antibiotics into bone cement is well accepted in revision surgery, but still debated for the primary operation. On-going research on bioresorbable ceramics and the incorporation of antibiotics more effective against coagulase-negative staphylococci should eventually counter late infections. As HIV-positive patients increasingly present with sepsis around implanted prostheses this need will increase. In vascular surgery as the risk factors for biomaterial infection are better understood, new generations of protein-sealed grafts are permitting ionically compatible antibiotic coatings. Large well-designed clinical trials have begun and are needed to confirm the forecast of improved long-term clinical outcomes.

Researchers analyzed data on 52 HIV-positive patients with Kaposi's sarcoma (KS) aged 23-67 (74% Black, 26% White; male/female ratio = 2.8:1) referred to the Johannesburg General Hospital in South Africa during 1980-1990 to examine the hospital's experience with these patients. 23 patients had a fever and/or at least 10% weight loss. 34% had prior or coexistent opportunistic infection, particularly Pneumocystis carinii pneumonia, fungal disease, or tuberculosis. Possible risk factors among 21 patients were homosexual intercourse, history of sexually transmitted disease, and drug abuse. Almost all patients had skin disease, either localized or disseminated. Other KS sites included the oral cavity, regional lymph nodes, and large bowel. 90% of 20 patients treated with radiation responded to treatment. Response rates for radiation treatment among the 20 patients were 80% for symptomatic relief, 45% for complete remission, 45% for partial remission, and 10% for tumor progression. The recurrence-free period among irradiated patients was five months. Five patients developed radiation-induced mucositis of the oropharyngeal region. None of the 32 patients treated with chemotherapy and not radiation experienced complete remission. Chemotherapy induced partial remission in 38% and tumor progression in 62% of patients. 9% of chemotherapy-treated patients experienced symptomatic relief. Deteriorating performance status and/or debilitating side effects (severe mucositis and neutropenic sepsis) necessitated cessation of chemotherapy or dose modification. The clinical course of AIDS-related KS in this population paralleled that in Western countries. Based on these findings, the authors recommend local radiation therapy to treat AIDS-related KS or a watch-and-wait policy for asymptomatic, minimal disease in patients with an intact immune status.

There is little information available on invasive group B Streptococcus (GBS) infection in pediatric patients older than 3 months of age. Review of infection control records at LeBonheur Children's Medical Center from January 1, 1986, to June 30, 1993, identified 143 patients with a positive GBS culture from normally sterile body fluid. Medical records of 18 (13%) patients > 3 months old with their first GBS infection were reviewed. Age range was 15 weeks to 18 years (median age, 13 months). Ten were black and 11 were girls. Five infants had a history of premature birth and 2 infants were infected with human immunodeficiency virus. The serotype distribution of 12 available GBS isolates was 4 type III, 2 each type V and Ia and 1 each type Ia/c, Ib/c, II and II/c. Bacteremia without a focus (9 patients) was the most common clinical manifestation. All 4 type III isolates were associated with bacteremia. One infant with human immunodeficiency virus infection had sepsis and bullous desquamation; a toxin-producing type V strain was isolated from her blood. Two adolescents with ventriculoperitoneal shunts had meningitis, including one whose cerebrospinal fluid also grew a type V strain. Other clinical manifestations were septic arthritis, endocarditis (Ia, II/c), central venous catheter (Ia/c) and ventriculostomy infections.

We find that induction of catabolic state changes the ratios of carbon 13 to carbon 12 in blood proteins. Diet can be inferred in growing chicks by feather carbon isotope ratios. This suggests an approach for early detection of catabolic state induced in patients with HIV, cancers that induce catabolism, infection onset, sepsis, kidney and liver disease, malnutrition and dietary problems. The technique would also be useful in animal husbandry.

HIV disease has reached epidemic proportions in Africa over the last decade and is severely stretching the health services of the many poor countries of the region. Increased sepsis during fracture surgery and the late infection of implants impels us to rethink many standard methods of treatment. Musculoskeletal infections, including tropical pyomyositis and long bone haematogenous osteomyelitis, are now common manifestations of advanced HIV disease in adults. Despite their severe infections, such patients may survive for more than 5 years and certainly cannot be written off as terminally ill. Treatment is often prolonged and, in the case of osteomyelitis, may necessitate amputation. These patients now occupy many of the available orthopaedic beds.

Despite the increasing number of patients with the human immunodeficiency virus (HIV) infection, surgical experience with these patients remains limited. A retrospective review over a 9 year period (January 1985 to December 1993) was undertaken to determine the indications, operative management, pathologic findings and outcome of major abdominal surgery in these patients. A total of 51 procedures were performed in 45 patients; 30 patients had acquired immunodeficiency syndrome (AIDS) and 15 patients had asymptomatic HIV infection. Indications included gastrointestinal bleeding, complicated pancreatic pseudocysts, cholelithiasis, bowel obstruction, immune disorders, acute abdomens, elective laparotomy, colostomy formation, menorrhagia and Caesarean section. Pathologic findings directly related to the HIV infection were found in 81% of the AIDS patients and 35% of the asymptomatic HIV infected patients (P < 0.05). These included opportunistic infections, non-Hodgkin's lymphoma, Kaposi's sarcoma, immune disorders, lymphadenopathy and pancreatic pseudocysts. It was noted that AIDS patients had more complications than asymptomatic HIV infected patients with most complications related to chest problems and sepsis (61 vs 7%; P < 0.01). Emergency operations carried a higher complication rate than elective operations though this was not significant. The hospital mortality was 12%. On follow up, 13 of the 25 AIDS patients had died with the median survival of 7 months, while three of the 14 asymptomatic HIV infected patients had died with the median survival of 40 months. Of the remaining patients, the 12 AIDS patients had a median postoperative follow up of 7 months and the 11 asymptomatic HIV infected patients had a median postoperative follow up of 29.5 months.(ABSTRACT TRUNCATED AT 250 WORDS)
