The prevalence of neonatal urinary tract infection (UTI) was studied in 1,762 high-risk neonates. Symptomatic bacteriuria was found in 1.9% and asymptomatic bacteriuria in 0.5% of these neonates. Male preponderance was 5:1. Clinical manifestations were extremely variable--vomiting, weight loss, and diarrhea being the prominent symptoms. Bacteremia was associated with UTI in six infants. The organisms identified in the urine obtained by suprapubic aspiration were Escherichia coli, Klebsiella, and Proteus. A mixed infection was found in four patients. Roentgenographic examination of the urinary tract showed abnormalities in 44% of the symptomatic patients. It is conclued that symptomatic high-risk newborn infants should be screened for bacteriuria, and that radiological investigations be preformed in those with proven infection.

The diagnosis of urinary tract sepsis is being made more often today because of increased awareness of the condition and improved techniques in the detection and management of genitourinary disorders. Patients developing urinary tract sepsis (bacteremia or septicemia) usually demonstrate certain predisposing factors: underlying chronic disease, advanced age, general debility, or recent urinary tract sepsis is easily made in a patient who has a sudden onset of fever, chills, malaise, nausea, and vomiting, along with tachycardia and a drop in blood pressure. Cultures should be taken from urine and blood samples, but therapy should be instituted immediately rather than after obtaining the results of cultures.

The nationwide incidence of group A streptococcal bacteremia in Sweden was 1.8 per 100,000 population in 1987. During the winter season 1988-1989, the reported cases rate doubled and then declined to the previous level. The peak was due to a type T1/M1 Streptococcus pyogenes strain associated with an increased case fatality rate (33% vs. 15% for other T types). The highest incidence rates were found in the age groups less than 12 months and greater than 70 years. Among a sample of 79 patients hospitalized in November or December 1988, a portal of entry, mainly cutaneous, was recognized in 89% of the patients and concomitant conditions in 67%. Among the clinical findings were signs of skin or soft tissue infection (41%), local or generalized pain (41%), vomiting or diarrhea (24%), cough (18%), and upper respiratory tract symptoms (12%). A fatal outcome was associated with high age, lower respiratory tract or unknown focus, leukopenia on admission, start of antibiotic therapy greater than 6 h after the patient's initial contact with a physician, and a rapid clinical course including multiple organ failure. Renewed awareness of the many facets of fulminant streptococcal infection represents one approach to minimize the case fatality rate.

We prospectively studied patients with enigmatic nausea and vomiting after allogeneic marrow transplantation to define the causes of this syndrome. Fifty consecutive episodes of persistent vomiting were investigated using physical examination and laboratory tests, endoscopic biopsies and brushings, and clinical follow-up for four weeks. Potential causes of vomiting were identified in 39 of the 50 cases (78%). Fifteen cases had gastrointestinal infections (mainly herpesviruses), 13 had unsuspected acute intestinal graft-versus-host disease (GVHD), 8 had intestinal infection plus acute GVHD, and 3 had other causes (subdural hematomas, bacteremia, and encephalitis). In the remaining 11 cases, no cause of vomiting was found. Endoscopy was necessary for diagnosis in 36 cases and required a combination of methods: routine histology, cytology, viral culture, and immunohistology using monoclonal antibodies to cytomegalovirus (CMV) and herpes simplex virus type 1. Patients with unexplained vomiting or intestinal GVHD had significant improvement of nausea and vomiting over the four-week observation period, but those with CMV did not (P = .01). We conclude that most allogeneic marrow transplant patients with enigmatic nausea and vomiting have gastrointestinal herpesvirus infections, acute GVHD, or both. Untreated CMV infections and persistent GVHD are associated with protracted vomiting in these patients.

To exploit possible dose-response and combination drug synergism, 20 previously untreated patients with extensive-stage small-cell lung cancer (SCLC) received one or two courses of high-dose induction chemotherapy consisting of cyclophosphamide (100 mg/kg), etoposide (1,200 mg/m2), and cisplatin (120 mg/m2) (HDCEP). HDCEP was followed by four cycles of standard-dose cyclophosphamide (1,000 mg/m2), doxorubicin (40 mg/m2), and vincristine (1.4 mg/m2) (CAV). Response was determined after HDCEP and following CAV. Reevaluation included repeat bronchoscopy and chest computerized tomography (CT), as well as repetition of all initially abnormal studies. All patients were evaluable for response and toxicity. Overall response to HDCEP was 90%, with a complete response (CR) rate of 65% (95% confidence limits, 44% to 86%) and a partial response (PR) rate of 25% (95% confidence limits, 6% to 44%). All patients either maintained or improved their initial response while receiving CAV. Median duration of response was 6 months (range, 2 to 12 months) and median survival was 9.5 + months (range, 2 to 21 + months). All 37 courses of HDCEP were associated with leukopenia (less than 1,000/microL), 92% with thrombocytopenia (less than 20,000/microL), and 84% with fever of greater than 38.5 degrees C. Additional toxicities included bacteremia (24%), nausea and emesis (59%), mucositis (57%), diarrhea (38%), and hemorrhagic cystitis (5%). There were two treatment-related deaths due to infection. A third patient died 4 months after completing HDCEP with pulmonary fibrosis. Although response duration and median survival were not improved, HDCEP produced a high CR rate in ambulatory patients with extensive-stage SCLC.

Employment of postoperative brain irradiation in the initial management of high-grade malignant glial tumors has now become standard. The addition of conventional chemotherapy to irradiation has not significantly improved median survival beyond 1 year. We treated 25 consecutive patients (13 pilot patients and 12 protocol patients) with histologically confirmed unresectable grade 3 or 4 malignant gliomas with high-dose BCNU (carmustine) followed by autologous bone marrow transplantation and whole brain irradiation. Within 3 weeks of initial surgery, each patient had autologous bone marrow stored (median 2 X 10(8) nucleated cells/kg), and then received BCNU 1,050 mg/m2 intravenously (IV). Peripheral granulocytes recovered (greater than 500/microL) at a median of 19 days (range, 10 to 37 days), and platelets recovered (greater than 20,000/microL) at a median of 18 days (range, 13 to 40 days), following bone marrow infusion. Patients received 60 Gy whole brain irradiation when granulocytes were greater than 1,500/microL. Toxicity was well tolerated. Nausea occurred in 19 patients (76%); however, only eight patients (32%) experienced vomiting (mild in three, moderate in five). Eleven patients (44%) did not require empiric antibiotics, six of whom never developed an absolute granulocyte count less than 500/microL. Three patients with a poor performance status died early (one seizure with vomiting and asphyxiation; one, klebsiella urinary tract infection (UTI) with bacteremia; one, candidal pneumonia), and one additional patient who was performing well died of pulmonary hemorrhage. The 13 pilot patients have now been followed for a median of 23 months, with a significant survival advantage compared with the 52 consecutive historical control patients who received similar surgery and radiotherapy without high-dose BCNU (P = .037). The overall study group of 25 patients also has a significant survival advantage when compared with the same historical control group, with a projected median survival of 26 months (P = .007). This new approach using early postoperative intensive therapy consisting of high-dose BCNU, autologous bone marrow transplantation, and whole brain irradiation appears to significantly improve survival.

We studied a selected series of febrile infants (N = 201) in an attempt to prospectively identify risk factors for bacteremia. Infants with fever less than 39.4 C, vomiting and diarrhea, croup, or viral exanthem or enanthem were not included. Twenty-one infants (9.5%) had positive blood cultures despite the initial judgment of their physician that only viral illness or localized bacterial infection existed. WBC count of more than 15,000 correlated with bacteremia, with a sensitivity of 0.71 and a specificity of 0.73. Extensive multivariate linear regression analysis attempting to increase predictive values was completed. The combination of fever higher than 39.4 C present for more than 12 hours and absolute polymorphonuclear count of more than 9,000 cells/mm3 had a sensitivity of 0.62 and a specificity of 0.78 for bacteremia. Descriptive statistics for groups with and without bacteremia are summarized. We have defined prospectively a population of infants with a high probability of bacteremia and a lower probability of viral illness. Identification of such a group is useful to the emergency physician because early antibiotic therapy may lessen morbidity and mortality. We conclude that an easily obtained data base may be useful in the prospective identification of those at risk for bacteremia.

Bacterial infections are frequent events in premature and newborn infants. The reason is a defective specific and nonspecific defence of bacterial organisms. Some immunoglobulins like IgM and IgA including secretory IgA are absent. Premature infants also show a decreased level of IgG. Cellular immunity is anatomically intact but functionally defective. A number of complement factors are lacking, the activation of the alternative pathway is impaired. Newborn infants with perinatal problems like asphyxia or difficult delivery, show defects of leucocyte function like decreased deformability, defective chemotaxis and defective killing of ingested bacteria. Certain diseases, like hypoxia and malformations of immature organ functions in this age group (decreased acid production in the stomach), facilitate bacterial colonization of surface epithelia and the invasion of tissues. Consequences of these pathogenetic mechanisms are an unimpaired propagation of bacterial organisms into the blood and meninges without localization of the infecting organisms at the entry site. Bacterial meningitis is not considered a separate disease entity but a complication of bacteremia and sepsis. Clinical symptoms are nonspecific at the onset of the infection. Fever is frequently absent; decreased appetite, vomiting, a bloated abdomen, diarrhea, tachycardia, tachypnea are early signs of a bacterial infection, a grey mottled appearance, cyanosis, jaundice, petechiae, apneic spells, seizure activity and a metabolic acidosis are symptoms of advanced infection. Successful treatment at this stage is often not possible. Every sign of a decreased well being of a newborn of premature infant warrants laboratory and bacteriologic work up for septicemia.(ABSTRACT TRUNCATED AT 250 WORDS)

Pseudomonas stutzeri bacteremia developed in six patients undergoing hemodialysis. Fever, shaking chills, nausea, and vomiting were observed. All patients recovered, although only two received specific antibiotic therapy. The infections occurred sporadically over a period of nine months. Pseudomonas stutzeri was subsequently isolated from the dialysate that circulates within the hemodialysis machine. The ultimate source was the deionized water that is combined with the liquid concentrate to form the dialysate. Pseudomonas stutzeri could be localized to the top cannister of the dialysis machine but was also isolated throughout the machine, including the bottom reservoir and the recirculating pump. The emphasis on handwashing, strict compliance with disinfection procedures, and elimination of prolonged sitting times for the filled machine after disinfection resulted in no further cases of P stutzeri infection.

Listeria bacteremia occurred in 2 pregnant women whose only common exposure was attendance at a party. The incubation period, the possibility of mild disease due to Listeria infection, and foods associated with risk of disease were evaluated. Ten (28%) of 36 party attenders met a case definition, which included isolation of Listeria monocytogenes from blood or stool or two of the following: fever, musculoskeletal symptoms, nausea, vomiting, diarrhea. One of 25 stool cultures was positive. The 2 blood isolates and 1 stool isolate were serotype 4b and identical by enzyme typing. The incubation periods for illness in the 2 pregnant women were 19 and 23 days. Consumption of large amounts of shrimp, nonalcoholic beverages, Camembert cheese, and cauliflower was significantly associated with illness. Eating shrimp remained a significant risk factor for illness after controlling for consumption of other foods. This study suggests a milder illness may exist in healthy persons who consume foods contaminated with L. monocytogenes and demonstrates a prolonged incubation period for disease.
