Abstract
Cutaneous tuberculosis (TB) may present in various clinical manifestations. Skin involvement may occur as a result of exogenous inoculation, contiguous spread from a nearby focus of infection, or by hematogenous spread from a distant focus. Because the clinical presentation of cutaneous TB can vary widely, it is important to have a high index of suspicion in appropriate clinical settings. In this chapter, the various clinical manifestations of clinical TB are classified by source of infection (exogenous, endogenous, and hematogenous spread). These are linked to the clinical appearance and histology of the skin lesions. Hopefully, this will resolve the confusion created by the myriad of terms previously used in the medical literature. Once a diagnosis of cutaneous TB is entertained, a biopsy for both culture and histopathology should be submitted. In some cases histopathology may show nonspecific inflammation without classic granuloma formation. In these cases, monoclonal antibodies and polymerase chain reaction (PCR) testing may be useful. In fact, in recent years, PCR amplification has proven to be invaluable in assisting identification of M. tuberculosis from skin biopsies in patients with negative TB cultures. In most instances, treatment of cutaneous TB requires combination chemotherapy. This is especially important in patients with extra cutaneous disease, multiple skin lesions, and those with profound immunosuppression. Surgery also may play both a diagnostic and therapeutic role.

Abstract
This review on pulmonary tuberculosis includes an introduction that describes how the lung is the portal of entry for the tuberculosis bacilli to enter the body and then spread to the rest of the body. The symptoms and signs of both primary and reactivation tuberculosis are described. Routine laboratory tests are rarely helpful for making the diagnosis of tuberculosis. The differences between the chest X ray in primary and reactivation tuberculosis is also described. The chest computed tomography appearance in primary and reactivation tuberculosis is also described. The criteria for the diagnosis of pulmonary tuberculosis are described, and the differential is discussed. The pulmonary findings of tuberculosis in HIV infection are described and differentiated from those in patients without HIV infection. The occurrence of tuberculosis in the elderly and in those patients on anti-tumor necrosis factor alpha inhibitors is described. Pleural tuberculosis and its diagnosis are described. Efforts to define the activity of tuberculosis and the need for respiratory isolation are discussed. The complications of pulmonary tuberculosis are also described.

Abstract
OBJECTIVES To assess the frequency of resistance of Mycobacterium tuberculosis to antituberculosis drugs and the factors associated with it among patients with tuberculosis (TB) and acquired immunodeficiency syndrome (AIDS). MATERIALS AND METHODS The medical records of TB and AIDS cases diagnosed from 1992 to 1997 in a public service for AIDS care were reviewed. RESULTS Resistance was diagnosed in 82 (19%) of 431 cases. The mean and median values between the diagnosis of AIDS and the diagnosis of TB were 214.8 days and 70.5 days, respectively. Multidrug-resistant TB (MDR TB) occurred in 11.3% of cases. Of the 186 patients with no previous treatment, 13 (6.9%) presented primary MDR TB. Of the 90 cases with previous treatment, six (6.7%) presented monoresistance to rifampin and 27 (30%) presented MDR TB. The distribution of cases with sensitive and resistant M. tuberculosis strains was homogeneous in terms of the following variables: gender, age, category of exposure to human immunodeficiency virus (HIV), alcoholism, and homelessness. Multivariate analysis showed an association between resistance and the two following variables: previous treatment and duration of AIDS prior to TB exceeding 71 days. The rates of primary multiresistance and of monoresistance to rifampin were higher than those detected in HIV-negative patients in Brazil. CONCLUSIONS In this patient series, M. tuberculosis resistance was predominantly of the acquired type, and resistance was independently associated with previous treatment for TB and with duration of AIDS prior to TB exceeding 71 days.

Abstract
Current theory in the molecular epidemiology of tuberculosis holds that tuberculosis cases harboring Mycobacterium tuberculosis strains with a common deoxyribonucleic acid (DNA) fingerprint are the result of recent M. tuberculosis transmission. Here we propose a mathematical approach independent of DNA fingerprinting to estimating the percentage of recent transmissions responsible for current tuberculosis incidence. The "short-term reproductive number" of tuberculosis is defined as the average number of tuberculosis cases developing within 1 year of infection. Multiplying the short-term reproductive number by the number of tuberculosis cases in each year and dividing by the subsequent year's tuberculosis case burden equals the proportion of tuberculosis cases in the subsequent year that are due to recent transmission. We carried out separate calculations for human immunodeficiency virus (HIV)-negative and HIV-positive tuberculosis cases. We applied the model to pulmonary (infectious) tuberculosis cases diagnosed in New York City during 1989-1993, using tuberculosis and AIDS surveillance data. Model-based estimates of the proportion of tuberculosis due to recent transmission were lower than estimates based on DNA fingerprints. Reconciliation of these divergent estimates may require the re-estimation of model parameters from data collected de novo, additional model development, and further advances in DNA fingerprinting methods.

Abstract
The objective of this study is to determine the different characteristics of human immunodeficiency virus (HIV) positive and negative patients treated for tuberculosis (TBC) in a tertiary hospital in Southern Brazil. We conducted a retrospective cohort study over a 5-year period, from January 1992 through December 1996. We reviewed medical charts of patients from our institution who received TBC treatment. We reviewed 167 medical charts of patients with confirmed TBC. HIV positivity was detected in 74 patients. There were statistically significant difference between HIV positive and negative patients in sex and age. HIV-infected patients showed significantly more signs of bacteremia than HIV-negative patients. Extra-pulmonary TBC was present respectively in 13 (17.6%) and 21 (22.6%) HIV positive and negative patients. There was a significant difference between chest radiograph presentation in HIV positive and negative patients. There were significantly lower hematocrit, hemoglobin, leukocyte and lymphocyte levels in HIV-positive compared to HIV-negative patients. Outcome was significantly different in the two groups with a death rate of 36.5% and 10.8% in HIV-positive and in HIV-negative patients. The difference between HIV positive and negative patients may have importance in the diagnosis, management and prognosis of patients with TBC.

Abstract
PURPOSE This study aimed to describe prevalence of and risk factors for HIV among persons with newly diagnosed class III (confirmed) and class V (suspected) cases of tuberculosis (TB) patients in Los Angeles County. METHODS HIV testing was performed on 1307 blood specimens after routine tests were completed at six TB clinics in Los Angeles County. HIV test results were matched to demographic and risk behavior information by use of an unlinked study methodology. RESULTS The overall HIV prevalence rate was 10.8%. By demographic characteristics, the highest prevalence rates were observed among persons born in the United States (15.7%), males (14.1%), blacks (14.3%), and those aged 30-44 years (14.4%). Confirmed TB cases (14%) were more likely to be HIV-infected than were suspect cases (9.6%). Risk behaviors associated with positive HIV serostatus included the injection of nonprescription drugs, having sex with an injection drug user, and use of noninjection forms of heroin, cocaine, and tranquilizers. Men who have sex with men were more likely to be HIV-infected than were heterosexual males. CONCLUSIONS HIV testing and counseling should be a standard of care in TB clinics. The observed high HIV prevalence rate reinforces the importance of designing prevention strategies that specifically target patients with TB.

Abstract
Tuberculosis of the liver is common in patients with acquired immunodeficiency syndrome (AIDS). Tuberculous liver granulomas in such patients are usually atypical. The liver granulomas may be even totally absent, but liver tissue usually reveals numerous acid-fast bacilli. Focal tuberculosis of the liver is a less common form of liver tuberculous infection. We present a 33-year old white homosexual man infected with the human immunodeficiency virus. He had three tumour-like lesions in the left liver lobe, which were subsequently diagnosed as focal hepatic tuberculosis with local hemorrhage. This unusual presentation of liver tuberculosis indicates the necessity of an aggressive diagnostic approach for the evaluation of focal liver lesions in patients with AIDS.

Abstract
SETTING Prediction of survival in Tanzanian patients with extrapulmonary tuberculosis (TB). OBJECTIVE To evaluate the prognostic value of clinical and laboratory parameters on survival in human immunodeficiency virus (HIV) seropositive and HIV seronegative patients with extrapulmonary TB. DESIGN Over an 8-month period 192 consecutive patients with extrapulmonary TB, admitted to a major referral centre in Tanzania, were enrolled in the study. Their symptoms, signs and PPD skin test were noted. Their sera were tested for HIV and analyzed for beta-2-microglobulin content. Univariate risk factors for 12 months' survival after the start of anti-TB chemotherapy were entered into a stepwise Cox regression model. Survival probabilities were estimated according to the number of risk factors. RESULTS Of the 192 patients 126 (65%) were HIV-infected, and 29.7% had disseminated TB. Thirty-five patients, of whom 24 (68.6%) were HIV-positive, withdrew from the study immediately after hospital discharge. For survival analysis 157 patients remained. Within 12 months' follow-up after initiation of anti-TB therapy, the case fatality rate of the 102HHIV-infected patients was 22% and of the 55 HIV seronegative patients 2% (P < 0.001). In the HIV seropositive patients the following independent risk factors were significantly associated with a decreased probability of survival: peripheral lymphadenopathy (Hazard Rate Ratio (HRR) 5.2, 95% Confidence Interval [CI] 1. 7-16.2), a decreased activity score (bedridden > 50%/day (HRR 4.5, 95% CI 1.7-11.7), lymphopenia of < 1000/microL (HRR 4.4, 95% CI 1.7-11.8), and mycobacteraemia (HRR 4.0, 95% CI 1.2-13-.1). An anergic PPD skin test reaction proved to be another independent risk factor when the analysis was performed on 89 patients with available Mantoux test results. In the HIV seropositive patients, the 12 months' survival probabilities were 93%, 86%, 54% and 0% for presence of 0, 1, 2, and > 2 risk factors respectively. CONCLUSION Estimation of survival probabilities in patients with extrapulmonary TB may be possible without performing CD4 cell counts.

Abstract
The ominous resurgence of tuberculosis after many years of containment necessitates a review of the various factors responsible. An intense collaborative effort is needed to avoid potentially catastrophic consequences of the new epidemic. To provide a basis for health education recommendations, the factors contributing to the resurgence of tuberculosis, the nature of the current epidemic, and past health education efforts are reviewed. Further, an expanded Health Belief Model is offered as a foundation to guide educational campaigns.

Abstract
BACKGROUND Pulmonary infection and tumor in the AIDS population has a variable clinical and radiographic presentation. The association between the radiographic presentation of pulmonary tuberculosis and CD4 T lymphocyte count in the HIV-infected patient is investigated in order to provide an empirical approach for early diagnosis, treatment, and isolation of infected subjects. METHODS A retrospective analysis of chest radiographs, CD4 T lymphocyte counts, and clinical history of 35 subjects from 3 urban hospitals was performed. All subjects were HIV-seropositive and had culture-proven pulmonary tuberculosis. Radiographs were evaluated for the presence of either a pattern characteristic of post-primary tuberculosis (typical pattern) or a pattern uncharacteristic of post-primary infection (atypical pattern). RESULTS Twenty-one of 26 subjects with a CD4 T lymphocyte count less than 0.20 x 10(9) cells/L, whereas only 1 of 9 subjects with a CD4 T lymphocyte count of 0.20 x 10(9) cells/L or more presented with an atypical pattern of pulmonary tuberculosis (p < 0.001). The mean CD4 T lymphocyte counts of those subjects presenting with atypical versus typical radiographic pattern of post-primary pulmonary tuberculosis were 0.069 x 10(9) cells/L (n = 22) and 0.323 x 10(9) cells/L (n = 13), respectively (p < 0.01). Twenty-one of the 22 subjects with an atypical radiographic pattern of pulmonary tuberculosis were significantly immunosuppressed (CD4 < 0.20 x 10(9) cells/L). Atypical radiographic pattern included diffuse and lower lobar opacities, pleural effusion, mediastinal adenopathy, interstitial nodules, and a normal chest radiograph. CONCLUSION AIDS patients presenting with CD4 count less than 0.20 x 10(9) cells/L and an atypical radiographic pattern for pulmonary tuberculosis are at risk for tuberculous infection requiring appropriate treatment and isolation until the diagnosis of pulmonary tuberculosis has been excluded.

Abstract
Persons co-infected with mycobacterium tuberculosis (MTB) and HIV are at increased risk for developing active tuberculosis. While extrapulmonary tuberculosis is particularly common in patients with AIDS, tuberculous pericarditis is a very uncommon complication of AIDS in the United States. We present a case of tuberculosis involving the pericardium and review the current literature on this topic.

Abstract
In a prospective study, we investigated whether human immunodeficiency virus (HIV) infection alters the clinical presentation in patients with tuberculous pleuritis. One hundred twelve of 118 patients who presented with pleural effusion suffered from tuberculosis (TB); 65 patients (58%) were HIV seropositive. Evidence of disseminated TB was found more often in HIV-positive than in HIV-negative patients (30.8% vs 10.6%, p < 0.02). Dyspnea, fever, night sweat, fatigue, and diarrhea, severe tachypnea, hepatomegaly, splenomegaly, and lymphadenopathy were significantly more common in HIV-infected than in HIV-negative patients with TB. The same applied to a negative Mantoux reaction, lower hemoglobin, higher beta 2-microglobulin values, and in pleural fluid, lower albumin and higher gamma-globulin levels. Among HIV-infected patients, PPD skin test anergy was significantly associated with relative low albumin and gamma-globulin levels of pleural fluid. However, the radiographic features did not differ with respect to HIV status; they were predominantly those of primary pleuritis (78% in each group). We conclude that coexisting HIV infection affects clinical and laboratory features, but not the radiographic presentation of patients with TB pleuritis in Tanzania.

Abstract
OBJECTIVES The aim of the study was to assess the incidence and aetiology of fever of unknown origin in human immunodeficiency virus (HIV)-infected patients, and to evaluate the usefulness of the main diagnostic procedures. DESIGN A retrospective study. SETTING AND SUBJECTS We reviewed the records of 270 HIV-infected patients who were hospitalized for the first time in a department of infectious and tropical diseases during the 27 month study period. MAIN OUTCOME MEASURES Fifty-seven patients (21%) had a history of fever of unknown origin. RESULTS The aetiology was found in 49 cases (86%). The major cause of the fever was mycobacteriosis: atypical mycobacteria in 10 cases, Mycobacterium tuberculosis in 10, mycobacteria of unspecified type in two, and BCG strain in one. A liver biopsy and a thoracic CT scan greatly contributed to the diagnosis of mycobacterial infection. Seventeen patients were given empiric antimycobacterial therapy as a therapeutic test, of whom seven had a favourable response. The other main causes of fever were cytomegalovirus infection in five patients, leishmaniasis in four, and lymphoma in four. CONCLUSIONS Fever of unknown origin is a frequent occurrence in the course of HIV infection, and mycobacterial infection should be considered as a first-line diagnosis in such cases. The place of empiric antimycobacterial therapy in the diagnostic strategy requires further evaluation, but appears to be an alternative to multiple investigative procedures.

Abstract
The incidence of tuberculosis has increased in recent years, at least in part as a result of the ongoing worldwide epidemic of acquired immunodeficiency syndrome (AIDS). In addition, the occurrence of outbreaks caused by multidrug-resistant Mycobacterium tuberculosis organisms has greatly heightened concern. In retrospect, a number of seminal studies that have appeared during the past decade have helped to define changing concepts concerning the epidemiology, pathogenesis, approaches to preventive care, diagnosis, and treatment of tuberculosis in HIV-infected persons. Such reports have shown that the variable clinical manifestations of tuberculosis in patients with AIDS are greatly influenced by the degree of HIV-induced immunosuppression. Explosive outbreaks of tuberculosis occurring in closed environments have emphasized that patients with AIDS and pulmonary tuberculosis may be highly contagious, especially when diagnosis and implementation of appropriate infection control measures are delayed. The extent to which homelessness and illicit drug use complicate management of tuberculosis have been examined, and the high risk of persons who are both tuberculin-positive and HIV-positive ultimately developing active tuberculosis, unless chemoprophylaxis is completed, has been clearly shown. The utility of sputum smears, bronchoscopy, and newer technologies such as polymerase chain reaction for diagnosis has been examined. The risk of relapse appears to be low when patients with AIDS with drug-sensitive tuberculosis complete appropriate multiple-drug therapy. Recent reports have addressed important hospital infection control, tuberculin testing, and chemoprophylaxis issues. This paper describes this evolution of understanding, focusing on reports that we believe have been conceptually important.

Abstract
Relata-se o primeiro caso de isolamento de Paracoccidioides brasiliensis (P. brasiliensis) em sangue de paciente HIV positivo, 28 anos, sexo masculino, natural de Nova Londrina que, ao exame físico e ultrassonográfico, apresentava esplenomegalia febril a esclarecer. Para estabelecer o diagnóstico etiológico, hemoculturas em triplicata foram realizadas para pesquisa de bactérias aeróbias, micobactérias e fungos. As hemoculturas para bactérias aeróbias e micobactérias foram negativas e P. brasiliensis foi isolado de duas hemoculturas, na fase leveduriforme em ágar BHI, 20 dias após a semeadura, a partir do meio de Negroni. O paciente classificado, segundo o "Centers for Disease Control (CDC)", no grupo IV devido a uma pneumocistose pulmonar, interrompeu o tratamento por problemas particulares na segunda dose de anfotericina B, sendo tratado alternativamente com 800 mg/dia de cetoconazol. O óbito ocorreu um ano após o isolamento do P.brasiliensis em hemocultura.

Abstract
In order to explore the genetic risk of a child with a family history of allergies developing asthma, allergic rhinitis, or atopic dermatitis, questionnaires filled in by 6665 families were analysed. The data were collected in a population based cross sectional survey of 9-11 year old schoolchildren living in Munich and southern Bavaria. The relation between asthma, allergic rhinitis, and atopic dermatitis and the number of allergic first degree relatives, and the type of allergic disease was examined. Analyses were done separately for families with single or multiple allergic diseases. In families with one allergic parent the risk of the child developing asthma was increased by asthma in a parent, with an odds ratio (OR) of 2.6 (95% confidence interval 1.7 to 4.0) but not by parental allergic rhinitis with OR 1.0 (0.7 to 1.5) or atopic dermatitis, OR 1.0 (0.6 to 1.6). For allergic rhinitis the highest risk with OR 3.6 (2.9 to 4.6) was observed with allergic rhinitis of one parent, apparently lower for asthma of one parent, OR 2.5 (1.6 to 4.0) or atopic dermatitis, OR 1.7 (1.1 to 2.5). Children with parental atopic dermatitis had a high risk for atopic dermatitis, OR 3.4 (2.6 to 4.4), compared with children with parental asthma, OR 1.5 (1.0 to 2.2), or parental allergic rhinitis, OR 1.4 (1.1 to 1.8). Risk factors in families with combined allergies of two relatives (parents and siblings) were analysed separately for the different combinations. These results support the hypothesis that asthma, allergic rhinitis, and atopic dermatitis are multifactorial diseases brought about by various familial and environmental influences.

Abstract
We conducted a population-based case-control study to determine the magnitude of the excess risk of tuberculosis in those infected with the human immunodeficiency virus (HIV) in Seattle-King County, Washington. Patients were 39 of the 54 cases of tuberculosis in white and in black (including Hispanic) men aged 20 through 49 reported to the Seattle-King County Department of Public Health between January 1986 and June 1988. Controls were 34 white and black men of similar age who had tuberculin testing as a condition of employment. Eleven (28 percent) of the 39 patients with tuberculosis and 2 (6 percent) of the 34 controls tested positive for antibody to HIV (odds ratio adjusted for age and race = 6.2; 95 percent confidence interval 1.2 to 31.9). Calculation of the etiologic fashion indicated that 24 percent of the tuberculosis cases in this population of young black and white men were attributable to concurrent HIV infection.

Abstract
The aim of the present study was to compare the clinical and radiographic presentation as well as the therapeutic outcome of pulmonary tuberculosis (PT) in adult patients with and without human immunodeficiency virus type 1 (HIV-1) infection in Kigali, Rwanda. Over a 17-month period 59 consecutive patients with bacteriologically and/or histopathologically documented PT were enrolled. Of these, 48 (81%) patients were HIV seropositive. Among these, 35 fit the WHO clinical criteria for AIDS (WHOCCA) at the time of admission. Significant differences were found between the HIV-seropositive and HIV-seronegative groups of patients: fever (85 versus 36%; p less than 0.001), tuberculin skin test anergy (69 versus 0%; p less than 0.01), mediastinal and/or hilar adenopathies (31 versus 0%; p = 0.05), and pleural effusion (43 versus 9%; p less than 0.05) were more frequently encountered in the HIV-seropositive group, and upper lobe infiltrates (55 versus 16%; p less than 0.02) and cavitation (91 versus 39%; p less than 0.003) were more often seen in the HIV-seronegative group. However, HIV-seropositive patients not meeting WHOCCA were less frequently anergic (0 versus 100%; p less than 0.001) and feverish (53 versus 97%; p less than 0.01) and more often had cavitation (69 versus 28%; p less than 0.02) and less often mediastinal and/or hilar adenopathies (7 versus 40%; p less than 0.04) compared with HIV-seropositive patients meeting WHOCCA. Under antituberculosis treatment, clearance of fever was slower in HIV-seropositive compared with HIV-seronegative patients, and among the HIV-seropositive group it was slower in those fitting WHOCCA.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In patients with acquired immunodeficiency syndrome (AIDS)-associated pulmonary Mycobacterium tuberculosis (MTB) (group 1), we analyzed whether the addition of transbronchial biopsy (TBB) and bronchial brushings augmented the diagnostic MTB yield over nonbiopsy sampling. Positive acid-fast bacilli (AFB) smears from combined sputum, bronchoalveolar lavage (BAL), and washings were 30 percent compared with 37 percent when brushings and TBB were added (p = NS). The addition of TBB increased culture yield from 96 percent to 100 percent (p = NS). Similar results were seen in patients with pulmonary MTB without human immunodeficiency virus (HIV) risk factors (group 2). Group 1 patients most commonly had a nonspecific inflammation on TBB histopathology and had a lower incidence of granuloma formation than group 2 (p less than 0.05). Our results suggest that more invasive sampling with bronchial brushings and TBB does not contribute to the microscopic, bacteriologic, or histopathologic diagnosis of pulmonary MTB, independent of AIDS risk factors.

Abstract
The marriage of two scourges, one old (mycobacterial disease) and one new (HIV), has presented an enormous challenge to the medical and public health communities, and has stirred renewed interest in mechanisms for immune control of mycobacterial infection. Virulence of both M. avium and M. tuberculosis appears to be inversely related to the capacity of the microorganisms to induce production of protective cytokines in infected hosts. TNF alpha and IFN gamma are central to this process, and mycobacterial polysaccharides may be their main determinant. Despite these similarities, M. tuberculosis and M. avium cause illnesses at the polar extremes of HIV disease. Tuberculosis, occurring early in the course of HIV disease, may promote HIV replication in otherwise latently infected cells via induction of cytokines. As such, the potential exists for accelerated progression to AIDS due to the mutual synergy of these pathogens.

Abstract
Between 1983 and 1989, we cared for 56 patients with tuberculosis and human immunodeficiency virus (HIV) infection. In 37 patients (66%), tuberculosis occurred before any other AIDS-defining disease (group 1); in 10 (18%) it occurred during the same month as another AIDS-defining disease (group 2); and in 9 (16%), after the diagnosis of AIDS (group 3). Tuberculosis was entirely pulmonary in 14 patients (25%), entirely extrapulmonary in 9 (16%), and both pulmonary and extrapulmonary in 33 (59%). The frequency of extrapulmonary involvement was similar in patients from group 1 and from groups 2 and 3 (combined): 76% versus 74%. Needle biopsy of the liver revealed hepatic involvement in 18 patients (32%). The mean CD4 lymphocyte count was 232/mm3 when tuberculosis was entirely pulmonary, and 243/mm3 when extrapulmonary disease was present (difference not significant). In group 1, the onset of both pulmonary and extrapulmonary tuberculosis occurred at the same stage of HIV infection, 12 and 10 months, respectively, before any other AIDS-defining disease. Treatment, planned to last 1 year, was highly effective, despite frequent side-effects. Among the 32 patients who completed treatment, relapse of tuberculosis occurred in 2 (6%) with a mean follow-up of 16 months (0-53 months) after completion. Our results suggest that pulmonary tuberculosis should be included in the criteria for diagnosis of AIDS.

Abstract
From January 1984 to October 1990, 140 of 392 (35.7%) patients with the acquired immunodeficiency syndrome (AIDS) were found to have had tuberculosis. One hundred and sixteen were intravenous drug abusers and 16 were homosexual men. Fever, cough, weight loss and generalised lymphadenopathy were common features of their illness. Tuberculin skin tests were negative in 74% and 55% had intraabdominal lymphadenopathy. The chest radiographs showed hilar lymphadenopathy and lower lobe interstitial or alveolar infiltrates, but rarely cavitation. Forty-one of our patients had pulmonary tuberculosis, 38 had extra pulmonary and in 61 it was disseminated. In 80 cases tuberculosis was the presenting feature of AIDS. Tuberculosis usually responded well to chemotherapy.

Abstract
The chest radiographs and medical records of 166 patients diagnosed as having clinically active pulmonary tuberculosis were reviewed. Forty-nine patients (group I) were seropositives to human immunodeficiency virus (HIV), and 117 patients (group II) did not have known risk factors for HIV infection. Roentgenographic abnormalities were analysed in the two groups, according to nine different radiographic patterns previously defined. The seropositive group had a significantly higher proportion of hilar and/or mediastinal adenopathy (P less than 0.001), infiltrates confined to the lower lung fields (P less than 0.05), and miliary tuberculosis (P less than 0.005). Otherwise, single cavitation and destructive pattern were more frequent in the group II. These data suggest that patients with pulmonary tuberculosis and HIV infection are much more likely to have atypical radiographic findings.

Abstract
BACKGROUND AND METHODS Infection with the human immunodeficiency virus (HIV) increases the risk of tuberculosis and may interfere with the effectiveness of antituberculosis chemotherapy. To examine the outcomes in patients with both diagnoses, we conducted a retrospective study of all 132 patients listed in both the acquired immunodeficiency syndrome (AIDS) and tuberculosis case registries in San Francisco from 1981 through 1988. RESULTS At the time of the diagnosis of tuberculosis, 78 patients (59 percent) did not yet have a diagnosis of AIDS, 18 patients (14 percent) were given a concomitant diagnosis of AIDS (as determined by the presence of an AIDS-defining disease other than tuberculosis), and the remaining 36 patients (27 percent) already had AIDS. The manifestations of tuberculosis were entirely pulmonary in 50 patients (38 percent), entirely extrapulmonary in 40 patients (30 percent), and both pulmonary and extrapulmonary in 42 patients (32 percent). The treatment regimens were as follows: isoniazid and rifampin supplemented by ethambutol for the first two months, 52 patients; isoniazid and rifampin supplemented by pyrazinamide and ethambutol for the first two months, 39 patients; isoniazid and rifampin, 13 patients; isoniazid and rifampin supplemented by pyrazinamide for the first two months, 4 patients; and other drug regimens, 17 patients. The intended duration of treatment for patients whose regimen included pyrazinamide was six months, and for patients who did not receive pyrazinamide, nine months. Seven patients received no treatment because tuberculosis was first diagnosed after death. Sputum samples became clear of acid-fast organisms after a median of 10 weeks of therapy. Abnormalities on all chest radiographs taken after three months of treatment were stable or improved except for those of patients who had new nontuberculous infections. The only treatment failure occurred in a man infected with multiple drug-resistant organisms who did not comply with therapy. Adverse drug reactions occurred in 23 patients (18 percent). For all 125 treated patients, median survival was 16 months from the diagnosis of tuberculosis. Tuberculosis was a major contributor to death in 5 of the 7 untreated patients and 8 of the 125 treated patients. Three of 58 patients who completed therapy had a relapse (5 percent); compliance was poor in all 3. CONCLUSIONS Tuberculosis causes substantial mortality in patients with advanced HIV infection. In patients who comply with the regimen, conventional therapy results in rapid sterilization of sputum, radiographic improvement, and low rates of relapse.

Abstract
Tuberculosis (TB) remains uniquely important among acquired immune deficiency syndrome (AIDS)-associated opportunistic infections: it presents the greatest public health hazard worldwide, is the most readily curable, and is largely preventable with existing means. Given the expanding pool of human immunodeficiency virus (HIV) seropositive persons, particularly in developing nations where Mycobacterium tuberculosis remains a leading health problem, one can expect a continued rise in TB cases during the 1990s. Global efforts to eliminate TB are now inextricably entwined with the effectiveness of measures to curtail the HIV epidemic. Mycobacterium avium complex infection, currently an intractable late complication of aids, may increase in clinical importance as success in managing other opportunistic infections and HIV disease itself improves. Understanding of the pathogenesis and management of mycobacterial diseases should increase rapidly given the renewed research spurred on by the advent of HIV.

Abstract
We describe the clinical features of 11 patients with human immunodeficiency virus infection in whom tuberculosis was undiagnosed and untreated prior to death. Most patients (9 of 11) had pulmonary complaints and 8 of 11 had roentgenographic findings suggestive of tuberculosis (hilar or mediastinal adenopathy, pleural effusion, apical infiltrate or miliary pattern). Despite these findings, tuberculin skin tests were not performed in any of the patients. Acid-fast smears of sputum were obtained in three cases and bronchoscopy performed in only four, reflecting the low index of suspicion for tuberculosis. Pneumocystis carinii pneumonia was the presumptive diagnosis in nine cases but was confirmed in only one case. Autopsy revealed tuberculosis as the cause of death in four patients. Of the seven patients who did not undergo autopsy, disseminated tuberculosis, manifest by mycobacteremia, was the only life-threatening illness identified and probably contributed to death. Increased awareness of the clinical and roentgenographic features of tuberculosis in HIV-infected patients, combined with more intensive use of acid-fast smears and tuberculin skin testing, are necessary in order to decrease mortality from this treatable complication of HIV-infection.

Abstract
Tuberculosis has now been well documented as a complication of infection with human immunodeficiency virus (HIV), but no studies concern patients requiring admission to the ICU. We report 12 cases of severe disseminated tuberculosis in patients who were seropositive for HIV. Eight patients had diffuse pulmonary involvement responsible for acute respiratory failure, 7 of whom required mechanical ventilation. Four developed septic shock, and in 3 blood cultures were positive for M. tuberculosis. Four patients had central nervous system involvement, with coma requiring mechanical ventilation 3 times. Rapid diagnosis was permitted in 10 patients by acid-fast smears of pulmonary specimens (8 patients) and/or tissue biopsies (4 patients). Seven patients died despite intensive therapy; autopsy was performed in 4 patients, showing disseminated tuberculosis. On the basis of this report, tuberculosis in HIV infection may present as an overwhelming systemic disease and thus requires an aggressive diagnostic and therapeutic approach.

Abstract
The relation between the acquired immune deficiency syndrome (AIDS) and tuberculosis (TB) was examined by matching the Illinois AIDS and TB registries. The match group was examined and compared with patients with only one disease by race, method of human immunodeficiency virus (HIV) transmission, site of tuberculous disease, radiographic findings, and results of Mantoux tests. The time of TB diagnosis was centrally distributed around the time of AIDS diagnosis; from this, it was determined that 4.1 percent of AIDS patients develop active TB. Projections for future AIDS cases were made by fitting a polynomial model to historical data. These projections were then used to predict the future impact of AIDS-related TB upon state TB rates. The rise in TB rates call for special efforts to minimize this impact.

Abstract
The objective of this study was to determine the prevalence of tuberculous infection and the incidence of active tuberculosis in homeless men attending a shelter-based clinic and to examine risk factors for acquisition of infection and development of active disease. The design was a prospective cross-sectional survey. Men were evaluated by standardized interviews using a questionnaire. Where indicated, skin testing with PPD, collection of sputum for smear and culture for acid-fast bacilli, and chest x-ray films were performed. The setting was an on-site clinic at a men's shelter in New York City. The patients were men attending the clinic for physical examinations for the work program or requesting evaluation of various medical problems. A total of 1,853 men were evaluated over a 73-month period. The overall rate of infection was 42.8 percent, including 27.0 percent with a positive PPD test, 9.8 percent with a history of a positive PPD test, and 6.0 percent with active tuberculosis. Increasing age, length of stay in the shelter system, black race, and intravenous drug use were found to be independently associated with tuberculous infection. Age, length of stay in the shelter system, and intravenous drug use were independently associated with active tuberculosis. We achieved a compliance rate of 36 percent completing treatment and 13 percent receiving treatment at the conclusion of the study.

Abstract
One-hundred and two patients with hemophilia A, hemophilia B, or acquired antibody to factor VIII who had undergone invasive procedures were cross referenced with patients participating in an ongoing prospective natural history study of HIV-1 infection in hemophiliacs. Matching revealed that HIV-1 status was known for 83 patients (83%) who had undergone 169 procedures between July 1979 and April 1988. Invasive procedures were classified as clean in 108 patients (63.9%), clean-contaminated in 45 (26.6%), contaminated in 2 (1.2%), and infected in 14 (8.3%). Wound infection rates by HIV-1 status were as follows (95% confidence intervals): HIV+ 1.4% (0% to 5%), HIV- 0% (0% to 9%), and procedure before testing HIV+ 1.5% (0% to 6%). There were no significant differences between the wound infection rates of HIV-positive and HIV-negative hemophiliacs nor in the wound infection rate among all three subgroups of patients (p greater than 0.5, Fisher's Exact Test). We conclude that surgery in HIV-1-infected patients who have not progressed to AIDS does not entail an increased risk of postoperative wound infections.

Abstract
The number of patients admitted to Muhimbili Medical Centre, Tanzania, with pericardial effusions rose after the epidemic of acquired immunodeficiency syndrome (AIDS) began. To investigate a possible relation all patients with suspected pericardial disease admitted between Oct 1, 1987, and March 31, 1989, were studied. 28 of 42 patients (67%) were seropositive for human immunodeficiency virus (HIV). 28 of 39 patients (72%) with pericardial effusion were HIV-seropositive compared with 0 of 3 without effusion. More HIV-seronegative than HIV-seropositive patients were receiving antituberculous chemotherapy and had ascites at enrollment. Only 5 of 28 HIV-seropositive patients had clinical signs of AIDS. 9 of 14 HIV-seropositive patients tested had positive Mantoux tests. There were no significant differences between the HIV-seropositive and seronegative groups in the duration of symptoms, laboratory results, X-ray or ultrasound findings, frequency of tamponade, or mortality. 38 patients were treated for tuberculosis. Pericardial effusion is strongly associated with, and an early manifestation of, HIV infection in Tanzania.

Abstract
The mycobacteria are an important group of acid-fast pathogens ranging from obligate intracellular parasites such as Mycobacterium leprae to environmental species such as M. gordonae and M. fortuitum. The latter may behave as opportunistic human pathogens if the host defenses have been depleted in some manner. The number and severity of such infections have increased markedly with the emergence of the acquired immunodeficiency syndrome (AIDS) epidemic. These nontuberculous mycobacteria tend to be less virulent for humans than M. tuberculosis, usually giving rise to self-limiting infections involving the cervical and mesenteric lymph nodes of young children. However, the more virulent serovars of M. avium complex can colonize the bronchial and intestinal mucosal surfaces of healthy individuals, becoming virtual members of the commensal gut microflora and thus giving rise to low levels of skin hypersensitivity to tuberculins prepared from M. avium and M. intracellulare. Systemic disease develops when the normal T-cell-mediated defenses become depleted as a result of old age, cancer chemotherapy, or infection with human immunodeficiency virus. As many as 50% of human immunodeficiency virus antibody-positive individuals develop mycobacterial infections at some time during their disease. Most isolates of M. avium complex from AIDS patients fall into serotypes 4 and 8. The presence of these drug-resistant mycobacteria in the lungs of the AIDS patient makes their effective clinical treatment virtually impossible. More effective chemotherapeutic, prophylactic, and immunotherapeutic reagents are urgently needed to treat this rapidly increasing patient population.
