Imipenem 2 g daily was administered intravenously to 40 evaluable patients with neutropenia and fever. Twenty-three patients had acute leukaemia and 17 malignant lymphoma. The overall response rate was 70.0%. Of the 14 patients with documented infection, 9 (64.3%) responded. Poorer responses were observed in patients with pneumonia (40%) or pseudomonal infection (50%). The response rate was significantly higher among patients with increasing neutrophil counts during therapy (P less than 0.02). Fungal infection was a common cause of treatment failure. Gastrointestinal side effects and skin rashes were occasionally seen. No patient developed central nervous system toxicity. Imipenem is a practical alternative to antibiotic combinations for management of neutropenic infection. However, careful monitoring is essential in the subgroups of patients with pneumonia or pseudomonal infections, who may require modifications of therapy.

We report three cases of T-ALL in which conventional cytogenetic analysis yielded normal karyotypes, but for which a new M-FISH technique (IPM-FISH) was able to detect a translocation. For these patients this technique highlighted a new, recurring and cryptic translocation t(5;14)(q35;q32) in childhood T-ALL which might be phenotypically restricted. The most innovative part of this technique is the use of interspersed polymerase chain reaction (IRS-PCR) painting probes that show an R-band pattern simultaneous with the combinatorial labeling. Contrary to the DOP-PCR, IRS-PCR-derived probes provide stronger hybridization signals at the telomeric ends that potentially increase the possibility of detecting cryptic translocations. All the IPM-FISH findings were validated by FISH with whole chromosome painting and unique sequence probes. These results demonstrate the efficient use of IPM-FISH as an improved, single-step method for the identification of cryptic chromosomal abnormalities. This new IPM-FISH technique is a good tool to display cryptic chromosomal abnormalities.

For the purpose of prevention of hospital-acquired infection caused by antibiotic-resistant bacteria, we examined a method to establish an appropriate time period for the administration of antibiotics to compromised hosts. Using these antibiotics we monitored patients who received instruction about the drug regimen in the Blood and Respiratory Diseases Department ward. We monitored a) third-generation cephalospolins, b) Imipenem/Cilastatin, and c) antibiotics used against methicillin-resistant Staphylococcus aureus. When the antibiotics were administered over 14 days, pharmacists notified physicians of the current duration of administration using a confirmation form, and confirmed their future administration schedule. We examined the antibiotic usage regimen of all the patients in this ward before and after the confirmation form was adopted. Patients given the same antibiotics within 14 days significantly increased in percentage from 82% to 91% after the confirmation form was adopted (p < 0.05). The median duration of antibiotic administration decreased from 7 days to 5 days. The case with antibiotic administration for the longest duration was a patient with leukemia who received vancomycin for 116 days after adoption of the confirmation form. This patient died 4 days after his antibiotic was changed. Only 16% of the patients administered antibiotics in this ward were monitored for the duration of antibiotic administration after adoption of the confirmation form. When the pharmacists positively provided physicians with information on some patients concerning the prolongation of antibiotics administration, the number of patients administered antibiotics for less than 14 days significantly increased throughout this ward without interfering with the treatment of patients who required long-term administration of antibiotics.

The orphan homeobox gene HOX11L2 was previously found to be transcriptionally activated as a result of the t(5;14)(q35;q32) translocation in three T-ALL cases. We now tested by RT-PCR Hox11L2 expression in 23 consecutive cases of T-ALL (15 children aged 0.8-14 years, eight adults aged 17-55 years) and as control 13 B-ALL patients from a single institution. Hox11L2 expression was undetectable in all patients with B-ALL, nor in adults with T-ALL. Nine children (60% of the cases), all boys, expressed Hox11L2. Blast cells from most of the latter patients carried surface CD1a, CD10 and not CD34 antigens, in contrast to the other children. FISH, M-FISH and IPM-FISH analysis failed to detect a t(5;14)(q35;q32) in one of them, which suggests a possible distinct genetic mechanism in Hox11L2 expression induction. Hence, Hox11L2 expression seems to be the most frequent abnormality in childhood T-ALL to date, comparable to the t(12;21) in child B-ALL.
