[Oncology patients in a pediatric intensive care unit--a 7-year experience].
BACKGROUND: As a result of improved therapeutic and diagnostic modalities the survival rate of children with neoplastic disease has increased dramatically. The consequences of these scientific advances have led to increased malignancy-related critical complications requiring the expertise of intensive care practitioners. PATIENTS: From all children admitted to the pediatric intensive care unit (PICU) of the Martin-Luther University Halle those with hematologic-oncologic condition were evaluated. RESULTS: From 4068 PICU admissions 196 (4.8%) oncologic patients were identified. Most of them were admitted for postoperative care, monitoring or intervention. 24 patients were admitted because of severe disease or treatment related complications. 14 out of 24 (58%) patients died on PICU. Mortality was significant higher in a subgroup requiring mechanical ventilation or suffering from sepsis. All patients but two with multi-organ system failure (> or = 2 organs) died. CONCLUSIONS: Children with neoplastic disease can benefit from pediatric intensive care unit (PICU) support. Successful treatment of life-threatening complications requires a close cooperation of pediatric oncology and PICU. Further studies are necessary to improve therapeutic strategies in oncology patients requiring PICU admission.

Comparison between human immunodeficiency virus positive and negative patients with tuberculosis in Southern Brazil.
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.
