From July 1986 through June 1990, 33,199 sera from various risk groups were collected in Veterans General Hospital-Taipei for detection of antibody against human immunodeficiency virus, type 1 (HIV-1). Sixty-five samples were proved positive by Western blot analysis. Among individual high risk groups, hemophiliacs had the highest positive rate of 20/60 (29.41%), followed by homosexual/bisexual males (41/1,264, 3.24%). The overall positive rate was 65/33,199 (0.19%). Ten cases were recognized as acquired immunodeficiency syndrome (AIDS), 1 case had AIDS-related complex (ARC) and 4 case had other apparently symptomatic infections. Among these 15 cases, 7 expired, 1 lost of follow-up and 7 surviving cases are being treated with zidovudine (AZT). Most of symptomatic HIV-1 antibody positive cases had abnormal T4/T8 ratio of 0.39 +/- 0.54 as compared with the asymptomatic HIV-1 carriers at a ratio of 0.81 +/- 0.69. The opportunistic infections included Pneumocystis carinii pneumonia (PCP) in 6 case, disseminated cytomegalovirus infection in 6 cases, herpes zoster virus infection in 3 case, candidiasis in 4 cases, syphilis in 3 cases, pulmonary tuberculosis in 2 cases, and others with cryptococcosis, salmonellosis, Mycobacterium avium-intracellulare infection, gonorrhea, Staphylococcus aureus endocarditis and bacterial sepsis, etc. The natural history of HIV-1 infection to AIDS involved acute and persistent multiple infections. Although prevalence of HIV-1 infection was low in Taiwan, nationwide surveillance of HIV-1 infection in various risk groups is still needed.

Between 1982 and 1990, 4 males with extensive intraurethral warts presented with marked inflammation of the external genitalia. When sepsis had settled all patients underwent ventral urethrotomy, in which the urethra was divided median as far back as was necessary to expose all of the warts. Surgical and electro-excision were the preferred methods of removal. Of 3 patients who developed recurrences 2 were lost to follow-up. A third remained without treatment for 1 year and when next seen the warts had spontaneously resolved and his urethra was closed. A fourth patient was lost to follow-up for 4 years before returning with destruction of his external genitalia by a verrucous carcinoma. The human immunodeficiency virus (HIV) did not appear to be a factor in the natural history of intraurethral warts in 2 patients who were negative for serum antibodies 2 and 8 years after presentation.

This is a case report of a 35-year-old woman infected with the human immunodeficiency virus who presented with acute bacterial sepsis that proved to be secondary to Neisseria gonorrhoeae. Typical skin and joint findings developed only after the acute sepsis had resolved. Patients with disseminated gonococcal infection rarely have signs of acute bacterial sepsis. This case raises the question of whether HIV-infected patients are at an increased risk of contracting severe gonococcal disease.

Before 1983, septic arthritis was rare in patients with hemophilia. With the advent of human immunodeficiency virus infection in the hemophilia population, many centers noted an increasing incidence of patients with septic arthritis. Fifteen septic joints in 10 patients with severe hemophilia were documented. Eight patients were human immunodeficiency virus positive, 1 was human immunodeficiency virus negative, and 1 was not tested. The diagnosis was delayed in 5 patients because the symptoms are similar to an acute hemarthrosis. An elevated temperature was common. The white blood cell count was elevated in only 1/3 of the infections, being modified by human immunodeficiency virus infection. Associated risk factors included infected angioaccess catheters (2), pneumonia (2), and generalized sepsis (1). All but 1 joint responded to appropriate antibiotics and either repeated aspiration or arthrotomy. However, 6 patients died of acquired immunodeficiency syndrome from 2 to 109 months after infection. Three patients are alive 29, 86, and 96 months, respectively, after infection.

Proinflammatory cytokines are important mediators during endotoxemia. In experimental models, injection of lipopolysaccharide (LPS) activates macrophages leading to excessive secretion of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1 beta and IL-6; infusion of high dose of these mediators results in organ failure and death. Natural infection may be different, because it persists over days or even weeks, with repeated endotoxin challenge to macrophages. Little is known about the capacity of peripheral blood mononuclear cells (PBMCs) to release proinflammatory cytokines under these conditions. Therefore, as an ex vivo model of sepsis, the expression of proinflammatory cytokines after stimulation of whole blood with LPS was studied. A high LPS dose (1 microgram/ml) maximally increased TNF-alpha, IL-1 beta and IL-6 secretion in controls, but a marked depression was observed in septic patients (p < 0.01; 15 patients with severe sepsis versus 20 control patients without infection). This reduction persisted for up to 10 days after diagnosis of sepsis. The release of TNF-alpha, IL-1 beta and IL-6 was markedly decreased in the septic group even when a lower and physiologically more relevant LPS concentration (1 ng/ml) was used. IL-1 beta mRNA was similar to controls, but a down-regulation was observed in TNF-alpha and IL-6 transcript levels in PBMCs from the blood of septic patients. This was at least in part due to a marked reduction in TNF and IL-6 mRNA half-life. These results indicate that different mechanisms down-regulate proinflammatory cytokine release in the whole blood of septic patients. Although excessive secretion is known to be deleterious, low concentrations of these cytokines are involved in regulating essential cellular and humoral immune functions. Thus, the reduced capacity to express and release adequate amounts of proinflammatory cytokines after exposure to endotoxin, as observed in whole-blood PBMCs from septic patients, may contribute to the development of immunodeficiency.

Fifty human immunodeficiency virus (HIV)-infected patients with perianal sepsis were studied. Seven (14 per cent) had serious septic complications, four patients with severe necrotizing gangrene, and three with abscesses in the mediastinum, liver and brain respectively. CD4+ lymphocyte counts were significantly lower in patients with severe septic complications as compared with those with uncomplicated perianal sepsis (P < 0.05). In patients with HIV presenting with rare (metastatic) abscesses, perianal sepsis must always be kept in mind as a possible focus. Although HIV-infected patients have a limited life expectancy perianal fistulas and abscesses should be aggressively treated, because of the high risk of severe complications.

Vascular nursing presents constant challenges. The natural history of vascular disease coupled with the complexity of the patient population provides an environment for constant learning. Providing care to these unique individuals demands a thorough knowledge of vascular anatomy and physiology, diagnostic interventions, treatment modalities, multidisciplinary resources, and nursing interventions. This case study explores the multifaceted realm of vascular nursing by examining the hospital course and multidisciplinary plan of care of a 22-year-old man whose hospital course began with a lower extremity deep venous thrombosis and progressed to pulmonary embolus, phlegmasia cerulea dolens, compartment syndrome, sepsis, arterial thrombosis, severe coagulopathy, priapism, laryngeal bleeding/laryngospasm, and subsequent notification of having received a unit of blood from a donor whose human immunodeficiency virus status was later determined to be positive. The intent of this article is not to define a specific means of practice but to share with colleagues the wealth of knowledge that was gained from this experience.

Twenty-five central venous lines (two external 23 subcutaneous ports) were placed in 19 boys with haemophilia A (n = 17) or B (n = 2). The mean age of the boys was 4.9 years (range 0.2-15.3 years). The haemophilia was severe (factor level < 1%) in 18 boys and moderate (factor level 3%) in one. Three boys had circulating inhibitors and three were positive for human immunodeficiency virus (HIV)-1 antibody. Central venous lines were placed to facilitate intermittent factor replacement therapy (n = 6), long-term factor prophylaxis (n = 9), induction of an immune tolerance protocol (n = 2) or therapy for acquired immunodeficiency syndrome (AIDS)-related complications (n = 2). The ports remained in place for 15795 days (mean 687 days, range 11-2059 days). The frequency of port-related sepsis was 48% (11/23 ports in eight boys) or 0.7 port infections per 1000 patient days. Ports were removed from five boys with an unresolved infection (four with Staphylococcus aureus sepsis and one with Pseudomonas sp. sepsis). Other complications requiring port removal included a catheter tip placed too high in the venous system (n = 1), severe persistent pain associated with needle access of the port (n = 1) and a subclavian vein thrombosis (n = 1). Both the benefits and risks of a subcutaneous port should be considered when deciding whether to place this device in a very young child with haemophilia.

A study prompted by the high number of human immunodeficiency virus (HIV) patients in the South African population was performed to evaluate the incidence of HIV in patients attending our Emergency Hand Service. Over a 6-month period, more than 500 consecutive emergency patients were tested for HIV. In our series, 24 patients tested HIV-positive. Of these, 14 presented with hand sepsis and 10 with hand injuries. Bacteriology was performed on all patients with sepsis to document bacteria type and sensitivity. CD4 counts (T4 lymphocyte counts) were done on 12 patients to assess immunocompetence. Other factors examined included hospital stay, number of operations, postoperative morbidity, and mechanism of injury. Results indicate that septic HIV patients spent more time in the hospital and required more operations than septic non-HIV patients. Furthermore, of all of the population of emergency hand patients, a larger percentage of HIV-positive persons than HIV-negative persons was likely to be seen for infection.

Human immunodeficiency virus (HIV) infection has radically changed African orthopaedic practice within a decade. In Lusaka, a third of adults are infected, but most have no physical signs of the disease. Early experience showed that closed fractures healed normally, the risk of sepsis during osteosynthesis was increased and most open fractures became septic. Major orthopaedic surgery in HIV-positive patients has increased risks of sepsis which rise steeply in those with physical signs of HIV disease. Musculoskeletal infections such as tropical pyomyositis, adult haematogenous long-bone osteomyelitis, and late haematogenous infection of implants, appear as immune competence wanes. There is a dual epidemic of tuberculosis and HIV, and bone and joint tuberculosis is now common. Atypical features suggest that traditional diagnostic criteria for spinal tuberculosis may be inadequate. Rheumatoid diseases, especially reactive arthritis, are common and serious complications of HIV disease. The risk of transmission of HIV between patient and surgeon is small, especially if recommended precautions are universally applied.
