Clinical and therapeutic features of 13 adult patients, diagnosed of Pneumonia Varicellosa are retrospectively reviewed, for the last ten years period, at Valle de Hebron General Hospital, Barcelona. Most of them had a cigarette consumption of over 20 per day, three of them showed simple chronic bronchitis criteria, and two had antibodies against HIV. Respiratory symptomatology, and dry cough, was present in 9 (75%), dyspnea in 7 (53%) and pleuritic pain in 6 (46%). Thorax radiology showed a bilateral interstitial pattern. IV aciclovir treatment was begun in patients with respiratory symptoms and hypoxemia (53%) with good therapeutic response.

The clinical features, microbiology, treatment, and outcome in 24 children diagnosed with lung abscess at Harare Central Hospital during 1979-88 were reviewed retrospectively. This condition is rare in children, and the present study is the first to address lung abscess in Zimbabweans. 17 (71%) of the 24 patients were male and their mean age was 4.9 years. The most common presenting symptoms were fever, cough, and breathlessness. Abnormal chest signs (e.g., localized dull percussion note, with amphoric or bronchial breathing) were detected in 18 cases. Foremost among the predisposing factors were measles (25%), empyema thoraxis (17%), and unconsciousness (13%). Bacteria were isolated from 18 children, with Staphylococcus aureus (8 cases), group A beta hemolytic streptococci (4 cases), and Pseudomonas aeruginosa (3 cases) the most common. Treatment consisted of bronchoscopy to aspirate pus from the bronchus and exclude foreign bodies as well as antibiotic administration. There were 6 deaths (25% case fatality rate). The prevention or prompt treatment of measles is urged to reduce further the incidence of this rare health condition. However, the spread of human immunodeficiency virus infection among children in sub-Saharan Africa is likely to be accompanied by pediatric lung abscess cases secondary to pneumonia.

We have used new specific primers and probe in a polymerase chain reaction (PCR) followed by Southern blot assays to detect Pneumocystis carinii in human bronchoalveolar lavage samples obtained from HIV-infected patients with pulmonary symptoms. To facilitate the procedure we developed a filtration technique without DNA extraction yielding a high sensitivity (18/18 positive results). The high specificity of the technique was shown by testing immunosuppressed patients without P. carinii pneumonia.

To determine the frequency and distribution of pneumonia in an intensive care unit (ICU), we retrospectively examined the records of 1,854 consecutive ICU admissions between January 1987 and April 1990. A total of 266 patients met criteria for pneumonia (unilateral or bilateral infiltrate by chest roentgenogram, plus 2 of the following: leukocyte count > 10 x 10(9) per liter, temperature > 38.5 degrees C, or culture of blood or sputum positive for pathogens). Pneumocystis carinii pneumonia in patients infected with the human immunodeficiency virus was the most frequent cause (28%) precipitating an ICU admission in this series of patients. Streptococcus pneumoniae (13%), Staphylococcus aureus (8%), Haemophilus influenzae (4%), and viruses (4%) were also commonly observed. Overall mortality was 20%. An APACHE II score of greater than 24, the need for intubation, and the presence of P carinii were predictive of increased mortality. Age, sex, and length of stay did not predict final results. Patients with P carinii pneumonia who required intubation had an overall mortality of 54%, which was higher than patients without P carinii pneumonia who required intubation (P < .05). Our experience shows the changing spectrum of pneumonia in ICUs. In contrast to reports of a decade ago in which S pneumoniae and Pseudomonas aeruginosa are cited as most common, P carinii is now most prevalent in our ICU. Although our findings reflect the increasing incidence of human immunodeficiency virus infection in San Francisco, California, they may also be pertinent to other areas in the United States where the incidence of this infection continues to increase.

Participants at a 1992 WHO/UNICEF consultation meeting on HIV transmission and breast feeding weigh the risk of death from AIDS with the risk of death from other causes. Breast feeding reduces the risk of death from diarrhea, pneumonia, and other infections. Artificial or inappropriate feeding contributes the most to the more than 3 million annual childhood deaths from diarrhea. The rising prevalence of HIV infection among women worldwide results in more and more cases of HIV-infected newborns. About 33% of infants born to HIV-infected. Some HIV transmission occurs through breast feeding, but breast feeding does not transmit HIV to most infants HIV-infected mothers. Participants recommend that, in areas where infectious diseases and malnutrition are the leading causes of death and infant mortality is high, health workers should advise all pregnant women, regardless of their HIV status, to breast feed. The infant's risk of HIV infection via breast milk tends to be lower than its risk of death from other causes and from not being breast fed. HIV-infected women who do have access to alternative feeding should talk to their health care providers to learn how to feed their infants safely. In areas where the leading cause of death is not infectious disease and infant mortality is low, participants recommend that health workers advise HIV-infected pregnant women to use a safe feeding alternative, e.g., bottle feeding. Yet, the women and their providers should not be influenced by commercial pressures to choose an alternative feeding method. Health care services in these areas should provide voluntary and confidential HIV testing and counseling. Participants stress the need to prevent women from becoming HIV-infected by providing them information about AIDS and how to protect themselves, increasing their participation in decision-making in sexual relationships, and improving their status in society.

Although pregnancy is infrequently complicated by pneumonia, lung infection by bacteria, viruses, and fungi can pose serious maternal and fetal hazards. Pneumonia may lead to preterm labor and certain infecting agents, most notably the HIV virus, can cross the placenta and lead to neonatal infection. There is some evidence that the incidence of pneumonia in pregnancy may be increasing among certain populations. In addition, infections caused by viruses (varicella and influenza) and fungal agents, ordinarily controlled by cell-mediated immunity, may be more virulent to pregnant women, thereby adding to maternal mortality. Beyond the influence of these pregnancy-induced changes in immunity, there are certain physiologic changes in pregnancy that make it more difficult for the pregnant woman to sustain any type of respiratory infectious insult. Certain types of pneumonias, particularly influenza and aspiration, may be avoided if patients at risk are identified and existing strategies for prevention are applied. When the pregnant women is treated for lung infection, the safety of antimicrobial agents must be considered, and therapy may differ from that used in the nonpregnant patient.

From May 1987 to July 1990, 45 cases of Hodgkin's disease (HD) were recorded by the French Registry of HIV-associated tumors. Thirty-nine patients were male and median age was 30 years. Twenty-two cases had mixed cellularity type (MC), 18 nodular sclerosis, two lymphocyte depletion and three were not classified. Thirty-four patients had advanced HD clinical stages (CS III and IV). Thirty-six patients (80%) presented with B symptoms. Bone marrow involvement was diagnosed in 12 patients. Mediastinal involvement was present in only 4/30 patients (12%). Risk groups for AIDS were homosexuality in 18 cases, intravenous drug abuse in 17, both in one, and other in nine cases. In 40 cases (89%), HD occurred before any AIDS-related episode. Median CD4 cell count at HD diagnosis was 304 cells/microliters. Seventy-nine percent of the patients achieved complete remission with standard therapy, but hematological and infectious complications were very frequent. The rate of progression to AIDS was 71% at three years and opportunistic infections (mainly pneumocystis carinii pneumonia) were the most frequent cause of death. Overall two-year survival was 41% (78% for patients with initial CD4 cell count higher than 300 cell/microliters and 0% for those with CD4 cell count lower than 300/microliters). HD-HIV has a specific clinical profile as compared to primary HD, with a predominance of MC type and advanced clinical stage, without mediastinal involvement (88%). This study provides a basis for future clinical trials on HD-HIV: intensity of chemotherapy should be adapted to CD4 cell count; pneumocystis carinii prophylaxis is mandatory in all cases. Zidovudine should be included during and after HD treatment; the potential role of hematological growth factors has still to be evaluated.

This study examines a population of inner-city crack cocaine users in Miami, Florida. Many study participants were also injection drug users; others were the sexual partners of injection drug users. In general, the self-reported health status of the study population was good, but men perceived their health in a more positive light than did women. HIV-seronegative men were most likely to report excellent or good health, and seropositive women reported the greatest incidence of poor health, regardless of the amount of crack use. Serostatus was statistically significant for women but not for men. Pneumonia was reported more frequently by women, while hepatitis and tuberculosis were reported more frequently by men. There was a significant gender difference in reported endocarditis among light users of crack, with more women that men reporting a history of endocarditis. Among sexually transmitted diseases, men reported more gonorrhea and women reported more syphilis. These gender differences were statistically significant only for heavy users of crack. A gender difference was evident in the HIV seropositivity rates, with 25.7% of men and 32.2% of women testing positive for antibodies to HIV. While this difference held true when frequency of crack use was controlled, the difference was not statistically significant. Women were significantly more likely than men to trade sex for drugs and/or money. Women who were heavy crack users traded most often and would be expected to be at correspondingly increased risk for HIV infection or transmission.

Several questions remain unanswered including the timing of perinatal transmission, maternal factors predisposing to perinatal transmission of HIV-1, the best methods for early diagnosis in the neonate, and means of preventing perinatal HIV-1 infection. Significant advances have been made in the early diagnosis of HIV-1 infection, and now it is possible to make a diagnosis in most infants by 6 months of age. Unfortunately, not all these techniques are commercially available, so this capability is limited to certain institutions and laboratories. The natural history of HIV-1 infection in children continues to evolve, particularly with increased prophylaxis of P. carinii pneumonia and the availability of antiretroviral therapy. Our challenges for the future are to prevent perinatal transmission, to develop new and better therapies for opportunistic infections and HIV-associated complications, and to improve outcome and prognosis.

IgG and IgM anti-cardiolipin antibodies were measured, by an ELISA technique, in the sera of patients with B hepatitis (28), infectious mononucleosis (10), chicken pox (12), HIV infection (20), acquired toxoplasmosis (41) and other infectious diseases [HBsAg+ chronic hepatitis (5), brucellosis (6), herpes zoster (4), boutonneuse fever (3), viral pneumonitis (4), rheumatic fever (2)]. Increased levels of anti-cardiolipin antibodies (aCL), at least in one immunoglobulin class, were detected in 37 out of 135 patients [27.4%; range: 7.3% (in the patients with toxoplasmosis) -80% (in the patients with HIV infection)]. Low or medium titer aCL were present in 28 patients, high titer in 9 (6 with HIV infection, 2 with chicken pox and I with lymphoadenopathic toxoplasmosis). None of the manifestations associated with aCL was present in the aCL-positive patients. Finally, positivity for aCL didn't seem to modify the clinical picture and the prognosis of the infectious disease.
