Previous descriptions of paratyphoid fever (PTF) are of limited value to the clinician who has had no experience with Salmonella enteric fevers. Sixty-two cases of PTF occurred in a healthy, homogeneous population. Findings supported by the literature included a seasonal incidence, initially seen symptoms of gastroenteritis and spiking fevers, and a high percentage of positive blood cultures. Unusual findings included the rarity of rose spots, patients with fever as their only symptom, two patients with transient papilledema, and two others with peripheral blood smears suggestive of acute leukemia. The findings of this study are compared with previous reports. Likely causes for divergent and contradictory information are inclusion of data from non-PTF states and study of populations with altered states of health.

Bacillus cereus, which used to be considered non-pathogenic, was isolated from the blood of a patient with acute leukemia who was receiving intensive chemotherapy. Fatal bacteremia developed with a clinical syndrome of acute gastroenteritis, followed by both meningoencephalitis with subarachnoid hemorrhage and multiple liver abscesses probably caused by infective vasculitis. Surveillance stool cultures revealed colonization with the organism prior to the onset of diarrhea, and repetitive blood cultures were found to be positive. Thus, this case suggested some new important clinicopathologic features of true B. cereus bacteremia complicating acute leukemia.

We describe here an unusual case of Edwardsiella tarda septicemia preceded by acute gastroenteritis in a patient with acute leukemia in complete remission receiving maintenance chemotherapy. She also had ulcerated rectal cancer with bleeding, which was thought to serve as the portal of entry into the blood stream. She was successfully treated with cefmetazole and gentamicin in combination. However, the concomitant resolution of chemotherapy-induced granulocytopenia may have had a favorable effect as well.

Four children, ages 3 to 8 years, developed pneumatosis intestinalis (PI) after allogeneic bone marrow transplantation (BMT) for acute leukemia or severe aplastic anemia. PI was detected at a median of 48 days (range, 10-63 days) after BMT and was associated with abdominal symptoms and clinical signs. All patients had severe systemic and/or high-grade cutaneous acute graft-versus-host disease (AGVHD) at some time after BMT and were receiving corticosteroids at the time of development of PI; however, PI was associated with concomitant severe AGVHD in only one patient. One patient with PI had Hafnia alvei bacteremia and another patient had gastroenteritis due to rotavirus and adenovirus. All patients were treated with supportive care and systemic broad-spectrum antibiotics, and PI resolved 2-16 days after onset. Two patients died with BMT-associated complications unrelated to PI. Multiple factors contribute to the development of PI after BMT, and the prognosis for recovery from PI is good with medical management alone. Overall survival in these patients is dependent on the frequency and severity of other conditions, such as AGVHD and opportunistic infections, after BMT.

Ceftazidime (CAZ) was evaluated for its safety and efficacy in 31 children. Of the 25 confirmed bacterial infections, 23 were cured by the CAZ therapy (efficacy rate, 92%). CAZ was assessed as effective in acute pharyngitis with vomiting (4), acute laryngitis (1), pneumonia (8), urinary tract infections (5), acute gastroenteritis (1), infection accompanying acute leukemia (septicemia suspected) (1), acute purulent meningitis (2) and abscess of the lateral cervical cyst (1). The main pathogens which responded to CAZ were H. influenzae, S. pyogenes, E. coli and P. aeruginosa. As adverse events, mild melena with prolonged prothrombin time (1) was found to be associated with the CAZ therapy. Half-life of the CAZ serum level was 0.97 +/- 0.10 hours, and urinary excretion was high. Penetration into the CSF in 2 cases of acute purulent meningitis was satisfactory. The data suggest that CAZ is a safe and effective injectable antibiotic when used in children with infections of CAZ-susceptible bacteria including P. aeruginosa.

Over a 23-year period, 17 patients with hematologic diseases developed Aeromonas bacteremia while in our hematology ward. Male predominance (14 patients, 82%) was seen, with a predilection for the elderly. Hematologic malignancies, especially acute leukemia, accounted for 15 (88%) of all patients. Cancer chemotherapy and neutropenia (15 patients each) were the most common preceding host conditions. Aeromonas bacteremia generally occurred in the second half of the year (July-December), with no exposure to water or fish. Seven recent isolates comprised Aeromonas sobria (five isolates) and Aeromonas hydrophila (two isolates). Twelve patients (71%) showed a clinical picture ranging from mild gastroenteritis to severe enterocolitis. Anorectal and hepatobiliary infections were also noted in a few patients. The overall mortality rate was 35%. Ten (77%) of the 13 patients who were treated with aminoglycoside plus cephalosporin or carbapenem survived in association with marrow recovery.

Patients receiving chemotherapy for acute leukemia were prospectively followed up to determine the frequency, nature and outcome, of episodes of infection during a 6 or 12 month period at each of the participating centres. A total of 605 cycles of chemotherapy were surveyed. Of these, 490 cycles were received by patients with acute lymphoblastic leukemia (ALL) and 115 by patients with acute non-lymphoblastic leukemia (ANLL). 241 episodes of infection were recorded during the survey: 179 among ALL patients and 62 among patients of ANLL. Infections were more common during chemotherapy for ANLL than for ALL, occurring in 54% (62/115) and 36% (179/490) of chemotherapeutic cycle respectively. A favorable response to empiric antibacterial agents was seen in 39% (23/59) of episodes in ANLL patients and 77% (134/174) of episodes among ALL patients. Infection presented as fever of unidentified origin in an overwhelming majority (63%) of episodes. Gastroenteritis and pneumonia occurred with a frequency of 11% and 10% while the frequency of all other diagnoses was 3% or less. Overall, E coli and Candida were the most frequently isolated organisms while Staphylococcus aureus and Group A Streptococci were the most frequent isolates from blood and throat swabs, respectively. A high degree of resistance to commonly used antimicrobial agents was seen among the most frequently isolated organisms. About 75% of episodes of infection which did not respond to antibacterial agents responded to empiric systemic antifungal therapy; although fungi were mycologically isolated in only a quarter of these instances. Oropharyngeal candidiasis occurred in association with 3% of chemotherapeutic cycles.
