The Jerusalem psychiatric mother-baby unit.

The Jerusalem mother and baby unit (MBU) is influenced by the psychoanalytical orientation of the staff, and the historical and cultural conditions surrounding the unit. Forty-three patients with 44 babies (one set of twins) were admitted in 13 years, a rate of admission far from the theoretical demand. Schizophrenia, schizoaffective disorder and mood disorders have been the major diagnoses in more than 50% of the patients. Mothers with schizophrenia were significantly more likely to be admitted sooner after the birth than mothers without schizophrenia (p = 0.025). One infant was separated from the mother on discharge and four recommendations for adoption were given.

[Treating mother and baby in conjoint hospitalization in a psychiatric hospital].

Since 1990 we have been admitting mothers with postpartum psychiatric morbidity together with their babies to our open psychiatric ward. The aim of conjoint hospitalization is to maintain and develop the bond between mother and baby while treating the mother's psychiatric disorder. The presence of the infant in the hospital allows both a thorough evaluation of the mothers' maternal ability and to use the infant as a facilitator of the mothers' recovery by engaging maternal functions. It prevents the infants from being placed in a foster home for the duration of the mothers' hospitalization. Readily available in Britain and Australia, such conjoint hospitalization is controversial and rarely available elsewhere. In the past 5 years we hospitalized 10 women with 11 babies (1 woman was hospitalized twice, after different births). All women had received psychiatric treatment prior to childbirth, but this was the first psychiatric hospitalization for 2 of them. Diagnoses (DSM-IIIR) were chronic paranoid schizophrenia (4), affective disorder (4), schizo-affective schizophrenia (1) and borderline personality disorder (1). 8 were suffering from active psychotic symptoms on admission. They were treated pharmacologically, received individual and group psychotherapy, and participated in all ward activities. Families were engaged in marital, family and/or individual therapy according to need. All participated in cognitive-behavior treatment tailored to individual need to build and enrich the mother-infant bond. All improved significantly and were able to function independently on discharge, but in 1 case adoption was recommended.

A randomized double-blind trial of vancomycin versus teicoplanin for the treatment of gram-positive bacteremia in patients with cancer.

In a prospective, randomized, double-blind study comparing teicoplanin and vancomycin for the treatment of gram-positive bacteremias in neutropenic patients, teicoplanin was given at 6 mg/kg of body weight every 24 h intravenously (i.v.) after initial loading every 12 h for three doses, while vancomycin was administered at 15 mg/kg every 12 h i.v. At enrollment, both groups were comparable in age, sex, underlying hematologic or neoplastic disorder, baseline renal functions, and incidence of neutropenia. Treatment was successful in 19 (90%) of 21 patients who received teicoplanin and 24 (96%) of 25 who received vancomycin (P = .58). Adverse reactions occurred more often in the vancomycin group (31%) than in the teicoplanin group (9%; P = .06) and were primarily cutaneous or gastrointestinal. In conclusion, teicoplanin was better tolerated than vancomycin, and no statistically significant difference in efficacy was detected with the sample size in this study.

Admissions to a psychiatric hospital during the Persian Gulf War.

A descriptive study of all the admissions to a psychiatric hospital in Israel during the first month of the persian Gulf War was carried out. There was no decline in the number of admissions, and all the admitted 31 patients were civilians. War-related symptoms were manifest at the admission of 12 patients. Delusions of war-related content were prevalent, sometimes with corresponding hallucinations; three cases with these features are described briefly. There appeared to be an over-representation of female patients whose families originated in the Persian Gulf area. These findings may help in the planning of psychiatric services for similar future emergencies.

Clostridial bacteremia in cancer patients. A 12-year experience.

Over 12 years, 136 episodes of bacteremia caused by clostridial species were documented. Eighty-three were monomicrobial, and 53 were polymicrobial. Gastrointestinal, genitourinary carcinomas, and acute leukemia were the most common underlying malignancies. Septic shock occurred in 29% of monomicrobial bacteremias and 45% of polymicrobial bacteremias and was associated with a high mortality rate. Acute hemolysis, gas gangrene, and diffuse spreading cellulitis occurred infrequently but were associated with a 100% fatality rate. Many infections caused by Clostridium perfringens and C. septicum were associated with abdominal disease. The most commonly isolated organism was C. perfringens, followed by C. septicum and C. sporogenes. Overall survival was 58%, but it was 66% for monomicrobial episodes and 45% for polymicrobial infections. All of the patients with bacteremia due to an aerobic gram-negative bacillus in addition to the clostridial species died of their infection. The most effective antibiotics were clindamycin, penicillin, metronidazole, and moxalactam. Surgical drainage of abscesses was an important component of therapy.

Single agent therapy for infections in cancer patients: a prospective randomized trial comparing three extended-spectrum cephalosporins.

Three hundred and twenty patients were enrolled in a prospective randomized trial comparing cefoperazone, ceftizoxime and ceftriaxone for initial therapy of infectious episodes in cancer patients. Patients with neutropenia were excluded. In 286 evaluable episodes, the response rates associated with the three agents were 77% for cefoperazone, 70% for ceftizoxime and 72% for ceftriaxone, with no statistically significant differences between the three treatment groups. The overall response rate for all episodes of pneumonia (64%) was significantly lower than the response rate for all other infections (81%; p = 0.002), and the mortality associated with pneumonia (9%) was higher than that associated with all other episodes (2%; p = 0.01). Patients with infections due to gram-negative organisms responded well to all three agents, whereas patients with gram-positive infections responded more favorably to cefoperazone. Two different schedules of ceftriaxone were used. The clinical response did not differ significantly between patients receiving ceftriaxone once daily and those receiving it twice daily. The incidence of superinfection and relapse was extremely low and all three agents were well tolerated. It is concluded that extended spectrum cephalosporins are effective as single agents for the treatment of infections in cancer patients with adequate neutrophil counts.

Beta-lactam regimens for the febrile neutropenic patient.

A total of 535 evaluable febrile episodes in neutropenic patients were randomly assigned to treatment with ticarcillin-clavulanate plus vancomycin (TV), ceftazidime plus vancomycin (CV), or all three antibiotics (TCV). The TCV regimen was significantly more effective than TV, considering all evaluable episodes, documented infections, gram-negative infections, and infections in patients with persistent severe neutropenia (less than 100 neutrophils/mm3). The results with CV were intermediate between TV and TCV. The toxicities were similar with all three regimens and consisted primarily of skin rashes. The TCV regimen is effective for empiric therapy of fever in neutropenic patients and probably should be utilized in preference to CV or TV, although its superiority over CV in this study was inconclusive.

Circadian variation in serum amikacin levels.

Variable serum amikacin levels have been reported in the same patient even after a steady state presumably has been reached. Therefore, the authors investigated the optimal schedule for monitoring serum levels of the drug in 50 neutropenic patients receiving continuous infusion amikacin therapy for infections. We found that levels obtained in the early morning hours were significantly higher than those obtained for the same patient in the evening. As these differences parallel those previously demonstrated for renal function, they may be explained by the pattern of drug clearance by the kidneys. We recommend that blood specimens for the detection of rising serum amikacin levels in a therapeutic setting be obtained in the early morning and at the same time each day so that meaningful comparisons of peak concentrations can be made. However, late evening samples should also be tested whenever dosage modifications are considered so that continuous therapeutic serum concentrations can be ensured.

Nosocomial infection caused by Xanthomonas maltophilia: a case-control study of predisposing factors.

Factors predisposing to clinically significant nosocomial infection with Xanthomonas maltophilia were examined in a matched case-control study using multivariate techniques. Sixteen cases occurred among cancer patients in a six-month period, including an apparent cluster of three cases in an intensive care unit. These infections were unusually serious; eight patients had disseminated infection caused by X maltophilia and six died as a result of their infections. Among the 64 factors that were examined, therapy with broad-spectrum antibiotics and central venous catheterization were found to significantly increase susceptibility to infection. Therapy with imipenem was more than ten times more frequent among cases than among controls (p less than .001). All fatal infections occurred in patients who had received imipenem, including two patients who died before the organism could be identified and appropriate therapy instituted. Infection with X maltophilia should be suspected in patients who develop superinfection while receiving imipenem, and prompt therapy should be instituted to improve chances of survival. Because a common environmental source of X maltophilia was not identified, further study is necessary to determine specific preventive measures.

Bacteremia caused by non-sporulating anaerobes in cancer patients. A 12-year experience.

The clinical, epidemiological and laboratory characteristics of bacteremia caused by anaerobic organisms other than Clostridium spp. in cancer patients are described and compared to other previously reported series. Of the 315 episodes, 246 (78%) were caused by a single organism and 69 (22%) were polymicrobial. The most common underlying malignancies were genitourinary and gynecological tumors, acute leukemia, and gastrointestinal malignancies. Most patients (94%) were febrile, and septic shock was documented in 24% of monomicrobial episodes and in 58% of those with polymicrobial infection. Soft-tissue infection was present in 44% of the cases, and it presented as tissue necrosis in 11%. The most common sites identified as the portal of entry were intra-abdominal abscesses, soft tissue, and the oropharynx. The most common organisms were Bacteroides fragilis (57%) and other Bacteroides spp. (22%). Most polymicrobial infections were caused by 2 organisms, the second most commonly another anaerobe or an aerobic gram-negative bacillus. The most active antibiotic in vitro was chloramphenicol. High rates of resistance to penicillin were observed not only among B. fragilis, but also among Bacteroides spp. The frequency of penicillin resistance increased throughout the study years. The overall survival was 70%. The cure rate for monomicrobial bacteremias was 76% vs. 51% for polymicrobial episodes. Infection was the cause of death in 20 and 16 episodes, respectively. The response rate for patients in septic shock was 47% in contrast to an 85% recovery rate for those without it. Ninety-five patients had documented abscesses accompanying the bacteremic episode. The most effective antibiotics were clindamycin and chloramphenicol. Overall response to penicillin was only 13%. Suboptimal responses were also observed for the antipseudomonal penicillins. High response rates (82%) were also obtained with cefoxitin, metronidazole, and moxalactam.

Necrotizing gas-forming infections in cancer patients.

Necrotizing gas-forming infections in cancer patients present some unique characteristics, such as nontraumatic, spontaneous clostridial gangrene and gangrene involving an ischemic tumor mass. These infections can be rapidly progressive and uniformly fatal without surgical debridement. We review ten cases of gas gangrene seen during an 18-year period. Four were caused by Clostridium species and six by other organisms. Neutropenia was present in seven patients. During the last nine years, Clostridium septicemia occurred in 54 patients; in only two of those patients did gas gangrene ensue.

Intestinal crytosporidiosis treated with eflornithine: a prospective study among patients with AIDS.

Twenty-two patients with the acquired immune deficiency syndrome (AIDS) and severe debilitating diarrhea caused by Cryptosporidium received eflornithine as therapy. Of 17 evaluable patients, 5 had complete resolution of diarrhea and negative follow-up stool examinations for Cryptosporidium. One patient responded but relapsed after cessation of therapy. Four patients had resolution of diarrhea and symptomatic improvement, but continued to excrete the organisms in feces. Seven patients did not respond to eflornithine therapy. Eflornithine may induce complete responses or palliation of diarrhea in some AIDS patients with intestinal cryptosporidiosis.

Haemophilus species bacteremia in patients with cancer. A 13-year experience.

We reviewed the clinical and laboratory presentation of Haemophilus species bacteremia at our institution, with special attention to predisposing and prognostic factors. Of 36 cases, 18 presented with pneumonia, 1 with cellulitis, and another with sinusitis. No cases of meningitis or endocarditis were detected. Most episodes were caused by Haemophilus influenzae, and the overall response rate to treatment was 72%. Factors including chronic obstructive pulmonary disease, alcoholism, prior splenectomy, and neutropenia did not play an important role in these patients' infections. Most of the isolates serotyped were found to be nontypable. The occurrence of ampicillin resistance was 6% throughout the study. Ampicillin, chloramphenicol, and second-generation cephalosporins were all effective therapeutic regimens. Bacteremia due to Haemophilus species remains an uncommon infection in patients with cancer, despite the predominance of traditional predisposing factors.

Treatment of systemic fungal infections with liposomal amphotericin B.

Forty-six patients with systemic fungal infections were treated with liposomal amphotericin B. Twenty-one patients had disseminated candidiasis, 19 had aspergillosis, and the rest had a variety of other fungal infections. Forty patients failed to respond to conventional amphotericin B therapy, and 6 patients were given liposomal amphotericin B because conventional amphotericin B caused severe side effects. Twenty-four patients had a complete response, and 22 patients failed to respond. No short- or long-term toxic reactions were observed. The acute side effects such as fever, chills, and potassium loss were infrequent and milder than those commonly observed with conventional amphotericin B. No chronic renal, hematologic, or central nervous system side effects were observed. Liposomal amphotericin B therapy was effective and less toxic than conventional amphotericin B therapy.

Cefoperazone plus mezlocillin for empiric therapy of febrile cancer patients.

Two dosing regimens of cefoperazone plus mezlocillin were compared in a prospective, randomized trial for therapy of febrile cancer patients. The two regimens were 5 g mezlocillin plus 2 g cefoperazone intravenously every four hours (higher dose) or 3 g mezlocillin plus 1 g cefoperazone intravenously every four hours (lower dose). Although the overall response rate was higher with the higher dose regimen (78 percent versus 66 percent, p = 0.04), the two regimens were comparable in patients with documented infections (72 percent versus 68 percent). Likewise, the two regimens were equally effective against those infections in which the pathogen could be determined (82 percent versus 82 percent). Serum bactericidal titers of at least 1:32 against a known pathogen were associated with a higher response rate than were titers of less than 1:32, but the higher dose regimen did not result in higher serum bactericidal titers. Hypoprothrombinemia was a side effect, especially with the higher dose regimen, before prophylactic vitamin K was routinely administered to patients. Since there were no major benefits with the use of the higher dose regimen of mezlocillin plus cefoperazone, the lower dose regimen is more appropriate for routine usage.

Randomized trial of beta-lactam regimens in febrile neutropenic cancer patients.

A three-arm prospective randomized trial was designed to compare the efficacies of piperacillin plus vancomycin, ceftazidime plus vancomycin, or all three drugs as initial therapy for fever in neutropenic cancer patients. The objectives were to determine whether a broad-spectrum penicillin was as effective as a broad-spectrum cephalosporin and whether two beta-lactam antibiotics were more effective than one. Four hundred and seventy of the 519 febrile episodes entered in the study could be evaluated for response. Ceftazidime plus vancomycin was significantly more effective than piperacillin plus vancomycin, considering all febrile episodes (79 percent versus 61 percent, p = 0.001), documented infections (79 percent versus 57 percent, p = 0.004), gram-negative infections (88 percent versus 47 percent, p = 0.001), and bacteremias (81 percent versus 51 percent, p = 0.01). The addition of piperacillin to ceftazidime (piperacillin plus ceftazidime and vancomycin versus ceftazidime plus vancomycin) did not improve the response rate and was associated with a significantly higher incidence of skin rash. Vancomycin plus ceftazidime provides adequate antibiotic coverage for initial treatment of fever in neutropenic patients. This combination was equally effective, less expensive, and less toxic than the double beta-lactam combination used in this study.

Central nervous system histoplasmosis. An unappreciated complication of the acquired immunodeficiency syndrome.

Involvement of the central nervous system (CNS) by Histoplasma capsulatum is a rare event. It is usually not included in the differential diagnosis of CNS lesions in patients with acquired immunodeficiency syndrome (AIDS). Herein are described four patients with AIDS and progressive disseminated histoplasmosis who had CNS involvement. Histoplasmosis in the CNS may produce meningitis, single or multiple brain abscesses, and may present with either a clinical picture of obtundation or a deteriorating space-occupying CNS lesion. Three of the four patients were treated with amphotericin B and had initial clinical response, but ultimately, all experienced a relapse and died from their infection.
