| use of a rapid differential stain for identifying pneumocystis carinii in bronchoalveolar lavage fluid. diagnostic efficacy in patients with aids. | identification of pneumocystis carinii involves silver stains which require several hours for processing. diff quik, a differential stain similar to wright-giemsa, requires less than 1 min and reproducibly stains trophozoites and intracystic bodies of p carinii. to determine the utility of dq for rapid detection of p carinii in bal fluid, we reviewed dq-stained slides of 50 bal samples from 36 patients seropositive for hiv+ who had undergone bronchoscopy with bal for evaluation of interstitial p ... | 1989 | 2465872 |
| type i reactions directed against pneumocystis carinii in aids patients. | type i allergy directed against pneumocystis carinii (pc) has been investigated in 14 patients with aids. the pneumocystis carinii pneumonia often shows a rapid and severe course, and type i allergy against the parasite might be a pathogenic co-factor in the interstitial lung inflammation. in twelve of the aids patients the clinical symptoms and course of illness indicated a pc pneumonia. the basophil histamine release test was used as a sensitive test to detect type i allergy against pc. eight ... | 1989 | 2465772 |

| silver staining of pneumocystis carinii in the rat's lung. | the backscattered electron imaging mode of the scanning electron microscope was used to study the ontogenetic acquisition of argyrophilia in pneumocystis carinii in rats. silver staining continually increased from the late trophozoite to the mature cyst stage. the silver uptake began with a fine outline at the surface of the bodies of the late trophozoites; their cellular extensions, however, did not stain. the oblate precyst forms acquired the silver in heterogeneous patches. on spherical cysts ... | 1989 | 2464648 |
| ultrastructural detection of carbohydrates in the pellicle of pneumocystis carinii. | the presence of carbohydrates in the pellicle of pneumocystis carinii was demonstrated by methenamine silver (ms) and thiocarbohydrazide-silver proteinate (tch-sp) staining techniques. an intense, positive reaction with ms was observed on both the electron-dense outer layer and the electron-lucent middle layer of the pellicle, whereas in the case of tch-sp only the outer layer stained well. the middle layer did not stain as intensely with tch-sp as with ms. this observation indicates that the pe ... | 1988 | 2461556 |
| combination chemotherapy and alpha-interferon in the treatment of kaposi's sarcoma associated with acquired immune deficiency syndrome. | thirteen men with a median age of 37 (range 28 to 46) years who had extensive kaposi's sarcoma associated with acquired immune deficiency syndrome (aids) were treated with combination chemotherapy and alpha-interferon. four patients had stage iii disease and nine had stage iv disease (one with pulmonary and eight with gastrointestinal involvement). treatment consisted of monthly courses of actinomycin d, 1 mg/m2, and vinblastine sulfate, 6 mg/m2, given intravenously on day 1, bleomycin, 10 mg/m2 ... | 1988 | 2458177 |
| human immunodeficiency virus infection in childhood. | acquired immunodeficiency syndrome is associated with considerable morbidity in infants and children. it is caused by human immunodeficiency virus (hiv) which can be transmitted vertically from mother to infant early in pregnancy. transmission might also occur via breast milk. although the exact transmission rate of hiv from mother to infant is not known, hiv can become a major threat to child survival. this threat is already present in africa where high seroprevalences have been reported among ... | 1988 | 2456715 |
| ultrastructural morphology and staining characteristics of pneumocystis carinii in situ and from bronchoalveolar lavage. | the ultrastructure of pneumocystis carinii obtained from rats by bronchoalveolar lavage (bal) was compared with organisms in situ. all developmental forms of the organism as seen in situ were present in the lavage fluid. trophozoites in situ were adhered to type i epithelium, had smooth surfaces, and were interdigitated with the underlying epithelium. nonadherent trophozoites in situ and trophozoites in lavage fluid were more pleomorphic and irregular in shape with tubular projections extending ... | 1988 | 2456381 |
| human antibody response to a strain-specific hiv-1 gp120 epitope associated with cell fusion inhibition. | pepscan analysis, performed using 536 overlapping nonapeptides derived from the htlv-iii b nucleotide sequence of the region encoding the external envelope protein of 120 kda (gp120), identified in the v3 region of gp120 a major binding site for antibodies of hiv-1-infected humans. the minimal amino acid sequence of this antibody binding site was demonstrated by multiple length scanning to be five to eight amino acids in length: (g)pgraf(vt), i.e. amino acids 312-319. a peptide (neu 21) containi ... | 1988 | 2456084 |
| pneumocystis carinii in sputum. comparable efficacy of screening stains and determination of cyst density. | to determine whether accurate quantification of pneumocystis carinii cysts in sputum is possible using currently available means and to determine the optimal stain for screening sputum for p carinii, we undertook a comparative evaluation of readily available stains: (1) diff-quik, a stain that provides tinctorial detail comparable with giemsa, (2) toluidine blue, and (3) silver methenamine on simultaneously thawed sputum samples containing p carinii. we also studied the diff-quik stain in combin ... | 1988 | 2456048 |
| passive immunoprophylaxis with specific monoclonal antibody confers partial protection against pneumocystis carinii pneumonitis in animal models. | pneumocystis carinii is an important cause of pneumonitis in the immunosuppressed host. little is known, however, about the biology of this organism. this report demonstrates that a mab, m5e12, previously shown to be directed against a surface antigen that is present on rat-, rabbit-, ferret-, and human-derived p. carinii, is capable of hindering the development of p. carinii pneumonitis in animal models of this infection when administered throughout the period of immunosuppression. it appears t ... | 1988 | 2454947 |
| [pneumocystis carinii: laboratory diagnosis. state of the art]. | in the light of the international literature and personal observation, the diagnostic techniques employed in pneumocystis carinii pneumonia (pcp), a major opportunistic infection of acquired immunodeficiency syndrome (aids) are reviewed. | 1988 | 2454420 |
| rapid noninvasive diagnosis of pneumocystis carinii from induced liquefied sputum. | pneumocystis carinii organisms cluster in alveolar casts. a method for concentrating alveolar casts in sputum specimens might improve the diagnostic usefulness of sputum studies in possible cases of pulmonary infection with pneumocystis carinii. the use of sputum induction to detect pneumocystis carinii was studied in 40 consecutive patients with known or suspected human immunodeficiency virus infection having bronchoscopy for evaluation of pulmonary disease. sputum produced by deep coughing ind ... | 1988 | 2454045 |
| modified toluidine blue o stain for pneumocystis carinii: further evaluation of some technical factors. | a modified toluidine blue o (tbo) stain for pneumocystis carinii cysts was evaluated with regard to the influence of (i) the age and extent of use of the sulfation reagent, (ii) the source of tbo, (iii) the tbo content of the staining solution, and (iv) the amount of tbo present in the alcohol wash solutions. all tbos evaluated, except for a new tbo obtained from roboz surgical instrument co., inc., washington, d.c., produced satisfactory results. each lot of tbo should be quality controlled bef ... | 1988 | 2452828 |

| activity of lipid-soluble inhibitors of dihydrofolate reductase against pneumocystis carinii in culture and in a rat model of infection. | trimetrexate and bw301u (piritrexim isethionate), lipid-soluble inhibitors of dihydrofolate reductase, are potent inhibitors of the growth of pneumocystis carinii in culture with wi-38 cells. inhibition was observed with 0.1 microgram of trimetrexate or bw301u per ml. trimethoprim is ineffective at 100 micrograms/ml in this culture system. both trimetrexate and bw301u were effective as prophylactic agents against p. carinii pneumonia in rats; trimetrexate at 7.5 mg/kg protected 9 of 10 rats, and ... | 1987 | 2445281 |
| localization of silver deposits on pneumocystis carinii treated with gomori's methenamine silver nitrate stain. | the question which portion of the pellicle of pneumocystis carinii is actually stained by the gomori's methenamine silver nitrate (gms) method was solved with the aid of electron microscopy. silver particles were specifically deposited on the electron-lucent middle layer of the precyst, cyst and ruptured cyst, whereas such deposition was not found on the pellicle of the trophozoite, probably due to the absence of the electron-lucent middle layer in the trophozoite. these deposits increased in pr ... | 1987 | 2444043 |
| production of a monoclonal antibody with specificity for the pellicle of pneumocystis carinii by hybridoma. | this study reports the establishment of cloned hybridomas between mouse myeloma cells (p3-x63-ag8, 6.5.3) and spleen cells from balb/c mice immunized with lung homogenates of nude mice (balb/c nu/nu) heavily infected with pneumocystis carinii. a hybridoma subclone, designated 1e12-8, produced antibodies of an igg1 subclass. using indirect immunofluorescent antibody techniques, the monoclonal antibody was found to be directed toward the pellicle antigen of air-dried p. carinii both in trophozoite ... | 1987 | 2438684 |
| plastic embedding evaluation of pneumocystis carinii pneumonia in aids. simultaneous demonstration of cyst and sporozoite forms. | to study the possible role of plastic embedding in the surgical pathologic diagnosis of pneumocystis carinii pneumonia, bronchial biopsy specimens from five patients with aids were examined using 0.9 micron thick methacrylate sections stained with silver methenamine borate and counterstained with toluidine blue. this technique was found to be superior to paraffin embedding in the demonstration of the fine structural details of both pneumocystis and the surrounding lung tissue. this method permit ... | 1987 | 2436496 |
| detection of pneumocystis carinii in lung-derived samples using monoclonal antibodies to an 82 kda parasite component. | monoclonal antibodies against pneumocystis carinii (pc) antigenic epitopes resistant to denaturing procedures were developed by immunization of mice with isolated parasites and a urea extract of infected human lung tissue. paraffin sections of infected lung tissue were used as antigen in the screening for reactive clones. the target antigen was identified as an 82 kda parasite specific component in immunoblotting. the antibody showed no cross-reactivity with human lung tissue and various rat tis ... | 1987 | 2435811 |

| pneumocystis carinii pneumonitis. the nature and diagnostic significance of the methenamine silver-positive "intracystic bodies". | the cyst forms of pneumocystis carinii in specimens stained with methenamine silver contain single or paired discrete foci of enhanced staining that measure 1-2 micron in maximum size. the nature of these foci and their location within the cysts have been disputed. we demonstrate by electron microscopy of silver-stained sections that the darkly stained foci correspond to a focal thickening of the cyst wall and are unrelated to sporozoites and other intracystic organelles. the morphology of these ... | 1985 | 2415010 |
| advantages of a modified toluidine blue o stain and bronchoalveolar lavage for the diagnosis of pneumocystis carinii pneumonia. | a modified toluidine blue o staining technique for pneumocystis carinii is described. an easily prepared sulfation reagent made with sulfuric and acetic acids was used. the stain can be employed for bronchoalveolar lavages and lung tissue touch preparations. most background material was removed by the sulfation reagent, slides were generally easy to read, and time from receipt of a specimen to reporting of results was approximately 1 h. p. carinii cysts were more easily visualized with this stai ... | 1985 | 2414314 |
| cytologic diagnosis of pneumocystis carinii infection by bronchoalveolar lavage in acquired immune deficiency syndrome. | twenty-six patients with pulmonary infiltrates and suspected acquired immune deficiency syndrome (aids) underwent 29 fiberoptic bronchoscopies, including bronchoalveolar lavage. seventeen of the 18 patients (94.4%) shown to have pneumocystis carinii pneumonia were diagnosed by examination of the bronchoalveolar lavage specimen. minor complications occurred in 7 of 29 total bronchoscopies and included transient fever and hypoxemia. bronchoalveolar lavage is a safe, easy and effective procedure fo ... | 1985 | 2413675 |
| the recognition of pneumocystis carinii in routine papanicolaou-stained smears. | using definite criteria it is possible to accurately evaluate routine papanicolaou-stained cytologic smears for the presence or absence of pneumocystis carinii. strict attention must be paid to the cellular environment and the background material intimately associated with the cells. in 133 cytology specimens evaluated from proximal and deep bronchial washings and brushings, 71 were considered positive for p. carinii and 62 were called negative. ten of the latter were either unsatisfactory or eq ... | 1985 | 2413674 |
| disseminated bilateral chorioretinitis due to histoplasma capsulatum in a patient with the acquired immunodeficiency syndrome. | a 31-year-old white male homosexual was healthy until march 1984, when he developed pneumocystis carinii pneumonia, which resolved with treatment. in april 1984 he developed fever, followed by hepatosplenomegaly, headaches, blurred vision, pancytopenia and pulmonary infiltrates. on june 11, intracytoplasmic yeast were noted within leukocytes on a peripheral blood smear, and amphotericin b was started. the patient developed progressive respiratory and renal insufficiency and died on june 13, 1984 ... | 1985 | 2413418 |
| aids and parasitic infections, including pneumocystis carinii and cryptosporidiosis. | aids is a disorder that the pediatrician must consider when evaluating children with a variety of clinical conditions, including overwhelming infection with a number of parasites. this article discusses these opportunistic parasitic infections, focusing on their link with aids. | 1985 | 2410851 |
| role of the microbiology laboratory in the diagnosis of opportunistic infections in persons infected with human immunodeficiency virus. | patients with defects in the immune system caused by infection with human immunodeficiency virus are predisposed to a variety of opportunistic infections, many of which can be diagnosed by conventional or special microbiological procedures. this article reviews the laboratory diagnosis of bloodstream, lower respiratory tract, gastrointestinal tract, and central nervous system infections in persons infected with human immunodeficiency virus. laboratories serving health care facilities in which a ... | 1990 | 2407217 |
| management of patients with asymptomatic hiv infection. | there has been extensive progress in the management of hiv infection. this especially applies to patients in the early asymptomatic stages of disease. management guidelines include counseling of all seropositive patients, medical evaluation, psychological support, and medical intervention. for the asymptomatic patient, important strategies currently recommended include a cd-4 cell count at six month intervals with the use of azt for those patients with counts of less than 500/mm3 and the use of ... | 1990 | 2406530 |

| pneumocystis carinii pneumonia in human immunodeficiency virus-infected patients. | pneumocystis carinii has taken on new importance with the emergence of the human immunodeficiency virus. it is the most common life-threatening opportunistic infection in the acquired immunodeficiency syndrome and eventually develops in 80% or more of those not receiving primary prophylaxis. this review focuses on the clinical presentation, diagnosis, treatment, and prophylaxis of p carinii pneumonia in patients with human immunodeficiency virus infection. | 1990 | 2405800 |
| clinical utility of liver biopsy in patients with serum antibodies to the human immunodeficiency virus. | patients with the acquired immunodeficiency syndrome (aids) frequently have liver dysfunction, which may be due to a number of causes. determination of the patients who are likely to benefit from liver biopsy, an invasive procedure, is therefore important. in this study, the results of liver biopsy in patients with aids were compared to those in human immunodeficiency virus (hiv)-infected patients without aids. | 1990 | 2405658 |
| the evolving challenge of pneumocystis carinii. a deadly opportunist in aids. | considerable progress has been made in the identification and treatment of pneumocystis carinii pneumonia related to acquired immunodeficiency syndrome (aids). prophylaxis, either primary or secondary, represents a major advance and should be used appropriately by physicians caring for patients infected with human immunodeficiency virus. yet with success come new challenges. centers for treatment of aids that aggressively use prophylaxis have seen a shift toward severe illness due to other patho ... | 1990 | 2405375 |
| reduced concentrations of igg antibodies to pneumocystis carinii in hiv-infected patients during active pneumocystis carinii infection and the possibility of passive immunisation. | the relationship between pneumocystis carinii antibody concentrations and acute pneumocystis infection was investigated by testing sequential samples of serum from hiv antibody-positive patients with respiratory symptoms and hiv-negative immunocompromised patients by means of an indirect immunofluorescence assay for specific igg antibodies to p. carinii. loss of circulating antibody at the time of active pneumocystis infection was observed in five patients with proven infection. three others sho ... | 1990 | 2405059 |
| kaposi's sarcoma in transfusion-associated acquired immunodeficiency syndrome. a case report and review of the literature. | kaposi's sarcoma in transfusion-associated acquired immunodeficiency syndrome is rare; to our knowledge, only four previous cases have been reported. we report a unique case of transfusion-associated acquired immunodeficiency syndrome in a 74-year-old woman. at autopsy, both lungs were extensively affected by kaposi's sarcoma, pneumocystis carinii, and cytomegalovirus infection. these three processes led to respiratory failure and accounted for her death. | 1990 | 2403779 |
| continuous positive airway pressure by face mask in pneumocystis carinii pneumonia. | we used continuous positive airway pressure (cpap) by face mask to treat 18 aids patients with pneumocystis carinii pneumonia (pcp) who were in hypoxic respiratory failure. candidates for mask cpap were conscious, not hypercarbic, and able to protect their airway on icu admission. treatment was effective and well tolerated. mean po2 rose from 62 to 158 torr, respiratory rate decreased from 51 to 32 breath/min, and pco2 was unchanged. mean duration of treatment was 4.5 days. only one patient deve ... | 1990 | 2403506 |
| outcome after assisted ventilation in children with acquired immunodeficiency syndrome. | twenty-two pediatric patients with aids required assisted ventilation during 27 pediatric icu (picu) admissions. patients were retrospectively divided on the basis of whether they required assisted ventilation for acute respiratory failure (arf) or for another reason. sixteen (59%) courses of assisted ventilation were for arf. the picu mortality rate was 81% for the arf group. eleven (41%) courses of assisted ventilation were for reasons not involving arf. the picu mortality rate for the group w ... | 1990 | 2403505 |
| the diagnosis of pneumonia in the immunocompromised child: use of bronchoalveolar lavage. | between january 1987 and december 1988, 26 immunocompromised children (aged 15 months to 17 years) underwent bronchoalveolar lavage (bal) for evaluation of pneumonia (chemotherapy for malignancy, 12; orthotopic liver transplantation, 9; other hematologic disease, 5). bilateral diffuse pulmonary disease was present in 25 children. all were receiving broad spectrum antibiotics. in addition, five were receiving antiviral therapy and two were receiving antifungal therapy. sixteen patients underwent ... | 1990 | 2401943 |
| [morphological changes in pneumocystis carinii in the alveolar space due to treatment with co-trimoxazole--comparison of clinical cases and experimental rats]. | in this study, transmission electron microscopy was employed to observe the morphological changes in pneumocystis carinii (p. carinii) in the alveolar space of patients and experimental rats treated with co-trimoxazole. experimentally, p. carinii pneumonia was induced in wistar rats by peritoneal injection of prednisolone and then treated with co-trimoxazole. the animals were divided into an untreated group and groups treated with co-trimoxazole for 3-9 days. in the untreated group, various form ... | 1990 | 2401809 |

| novel pentamidine analogs in the treatment of experimental pneumocystis carinii pneumonia. | we have recently demonstrated that substitution of imidazoline moieties for the amidine groups of pentamidine produces a molecule that is effective against rat pneumocystis carinii pneumonia and that is apparently less toxic than pentamidine. for this reason, 10 novel imidazoline substituted compounds were evaluated for their effect against rat p. carinii pneumonia. while several of the new compounds were observed to have advantages over pentamidine in the treatment of disease in the rat model, ... | 1990 | 2393262 |
| oral therapy for pneumocystis carinii pneumonia in the acquired immunodeficiency syndrome. a controlled trial of trimethoprim-sulfamethoxazole versus trimethoprim-dapsone. | antimicrobial drugs that can be taken orally are needed for the treatment of pneumocystis carinii pneumonia in patients with the acquired immunodeficiency syndrome (aids). preliminary data indicate that dapsone with trimethoprim may be an effective alternative to trimethoprim-sulfamethoxazole, which is frequently toxic. | 1990 | 2392131 |
| the emerging aids epidemic in ireland--clinicopathological findings in 23 early cases. | a longitudinal study with follow up to the end of 1989 was carried out on 23 patients with aids who had attended st. james's hospital, dublin, by the end of 1987. until then only 33 cases of aids had been reported in ireland. the patients, all of whom had antibodies to human immunodeficiency virus (hiv), were predominantly male, young (mean age 31.3 years) and belonged about equally to three major risk groups: homosexuals, intravenous drug abusers (ivda) and haemophiliacs. aids was diagnosed bec ... | 1990 | 2391209 |
| scintigraphic pattern of pneumothorax complicating pneumocystis carinii pneumonia in patients with aids. | spontaneous pneumothorax is a serious though infrequently reported pulmonary complication of aids. an unsuspected lung collapse was discovered via gallium scintigraphy for the study of pneumocystis carinii pneumonia. neither the pneumonia nor the pneumothorax were apparent on the most recent chest roentgenogram. in evaluating gallium images during the work-up of aids patients with associated pulmonary pathology, the possible complication of lung collapse should be considered. if pneumothorax is ... | 1990 | 2390822 |
| anti-cardiolipin antibodies and hiv infection. | anti-cardiolipin antibodies of igg class were found in 48% of intravenous drug users, 38% of homosexuals and 14% of heterosexuals (with no other risk factor) infected with hiv. anti-cardiolipin antibodies were not increased in hiv-negative heterosexual partners of hiv-infected patients, but mildly elevated levels were detected in hiv-negative drug users, relative to healthy controls unselected for hiv status. among hiv infected drug users, anti-cardiolipin antibodies were not associated with thr ... | 1990 | 2387093 |

| severe community-acquired pneumonia. etiology, prognosis, and treatment. | the frequency of community-acquired pneumonia coupled with its mortality rate of 10 to 25% is of growing concern to clinicians. a prospective study of 67 patients with severe community-acquired pneumonia was carried out to determine the causative agents, the impact fore-knowledge of the etiology has on the outcome, the value of clinical and radiologic criteria in predicting the evolution, and the efficacy of empirical therapy. the study group included 45 men and 22 women (mean age: 56.8 +/- 16.6 ... | 1990 | 2382902 |
| acquired immunodeficiency syndrome and pneumocystis carinii infection in a pregnant woman. | human immunodeficiency virus (hiv) infections are being seen with greater regularity by the obstetrician-gynecologist. acquired immunodeficiency syndrome (aids), the extreme of the spectrum of hiv infections, is associated with pneumocystis carinii infection in more than half of newly diagnosed cases. four cases of aids and p carinii pneumonia complicating pregnancy have been reported in the literature, and all have caused maternal death. we report a case in which the mother survived. treatment ... | 1990 | 2381630 |
| application of immunoblotting to detect soluble pneumocystis carinii antigen(s) in bronchoalveolar lavage of patients with pneumocystis pneumonia and aids. | the technique of immunoblotting for detecting soluble pneumocystis carinii antigen(s) in bronchoalveolar lavage fluid specimens from patients with aids and pneumocystis pneumonia was evaluated. a soluble 67 kilodalton polypeptide that was immunoreactive with an anti-p carinii monoclonal antibody (2g2) was found in the supernatants of 26 lavage samples from patients with pneumocystosis. intact organisms in lavage sediments were detected by methenamine silver or immunofluorescence staining procedu ... | 1990 | 2380406 |
| plasma fibronectin concentrations in patients with human immunodeficiency virus infection. | plasma fibronectin (pfn) concentrations were assessed in 21 patients with aids, in seven with aids-related complex (arc), in 17 asymptomatic seropositive patients, and in 36 age and sex matched healthy control subjects. a single radial immunodiffusion technique was used to determine pfn concentration. a significant decrease in pfn concentrations was observed in patients with arc and aids (especially in those patients with pneumocystis carinii pneumonitis). on the other hand, normal pfn concentra ... | 1990 | 2380404 |
| semiquantitative technique for estimating pneumocystis carinii burden in the lung. | we developed a technique to estimate the amount of pneumocystis carinii found in bronchoalveolar lavage fluid. p. carinii associated with 500 nucleated cells in the bronchoalveolar lavage fluid had little between-observer and within-observer variation. varying the technique of the lavage did not change the amount of p. carinii recovered. this technique was used in patients treated for p. carinii pneumonia. those patients who did not respond to treatment had more p. carinii in their bronchoalveol ... | 1990 | 2380366 |
| growth and metabolism of pneumocystis carinii in axenic culture. | recent analyses of rrna have suggested a taxonomic relationship of pneumocystis carinii with fungi. we investigated various liquid and solid media without feeder cells for the ability to support growth of p. carinii. organisms were obtained from the lungs of immunosuppressed rats and separated from host cells by treatment with hypotonic solutions and a series of microfiltrations. the growth of p. carinii was quantitated by staining nuclei with diff-quik. optimal replication was observed in media ... | 1990 | 2380365 |
| pneumocystis carinii choroiditis after long-term aerosolized pentamidine therapy. | pneumocystis carinii pneumonia is a major cause of morbidity and mortality in patients with the acquired immunodeficiency syndrome. when p. carinii is disseminated, the choroid may be involved and the infection is often fatal. we examined, treated, and followed up two patients who developed choroidal lesions typical of p. carinii while taking aerosolized pentamidine for prophylaxis. the choroidal lesions gradually resolved after three weeks of therapy with intravenous trimethoprim and sulfametho ... | 1990 | 2378374 |
| [herpes simplex infections in patients with aids]. | herpes type infections in aids patients tend to be more severe, generalized and have a torpid evolution. we present here two cases of intravenous drug addicts with a clinical picture of ulcerative lesions with a scar in the perioral and ungual regions with an evolution of several months an which were diagnosed of herpes simplex by a histopathological study. they were treated with intravenous acyclovir achieving a complete remission; one patient developed a pneumocystis carinii pneumonia a month ... | 1990 | 2377775 |
| [the value of fiberoptic bronchoscopy in diagnosis of hiv associated infections]. | 32 patients with hiv infection presenting with fever or abnormal chest radiograph or both were investigated at the university hospital of mainz (frg). fiberoptic bronchoscopy with bronchoalveolar lavage and transbronchial biopsy was undertaken in each patient, additionally other methods were used for isolating pathogens (i.e. urine sample, stool and blood culture etc.). in 26 patients one or more complicating diseases were documented, in six persons no reason for fever or pulmonary symptoms coul ... | 1990 | 2377146 |

| the relation between resource use and in-hospital mortality for patients with acquired immunodeficiency syndrome-related pneumocystis carinii pneumonia. | a central issue in health policy with regard to the acquired immunodeficiency syndrome (aids) is whether quality of care and patient outcomes are affected by resource constraints. in an earlier study of 15 california hospitals between october 1986 and october 1987, we observed a markedly lower in-hospital mortality rate for pneumocystis carinii pneumonia in the group of patients treated in hospitals that had a high level of experience with aids relative to the group treated in hospitals with low ... | 1990 | 2369243 |
| [intensive care problems in aids patients]. | the discussion regarding the need for intensive-care treatment of aids patients should be conducted in a highly differentiated manner and should depend on the prognosis of the underlying or basic disease, on the immunological situation, on the mental condition and on the consent of the individual patient. during the past two years the treatment results have improved markedly by the use of steroids, especially in pneumocystis carinii pneumonia. | 1990 | 2367423 |
