We experienced 57 episodes of Pseudomonas aeruginosa bacteremia in 55 patients with hematologic disorders in a 16-year period. Ninety-five percent of the patients had hematologic malignancies such as acute leukemia. All but one patient received cytotoxic or immunosuppressive therapy at or prior to the onset of bacteremia. Seventy-seven percent of the episodes occurred during profound granulocytopenia of below 100/mm3. All the patients acquired their infection in the hospital, and 96% had received antibiotic therapy during the preceding two weeks. Periodontal, anorectal, lower respiratory tract, and urogenital infections were the sources of bacteremia in about three-quarters of the episodes. Periodontal infection tended to progress to cellulitis of the face or the floor of the mouth, often resulting in bacteremia of the unimicrobial type, while anorectal infection predisposed to abscess formation, frequently leading to bacteremia of the polymicrobial type. Cellulitis at onset was seen in 35% of the episodes. Most sites of infection did not become apparent until one to three days after the onset of fever, probably because of depressed inflammatory response associated with severe granulocytopenia. The majority of patients complained of gastrointestinal symptoms such as nausea and vomiting, abdominal pain, diarrhea, and abdominal fullness at the onset of bacteremia. Major complications included bacteremic shock (63%), impaired consciousness (25%), ecthyma gangrenosum or hemorrhagic gangrenous cellulitis (18%), and jaundice (12%). Furthermore, there were one case each of endocarditis and disseminated intravascular coagulation. It was thus suggested that the clinical picture of P. aeruginosa bacteremia complicating hematologic disorders is influenced by the predisposing conditions associated with the underlying diseases and their treatment.

Thirteen patients with Aeromonas species septicemia were seen at Westmead Hospital between 1983 and 1987. In 10 patients (77%) septicemia was caused by A. sobria, and in 3 (23%) by A. hydrophila, A. caviae was not isolated. Chronic underlying illness was present in 10 patients (77%), hematological malignancy being the most common (46%). The average age of the patients was 65.8 years. Seven patients (54%) presented with clinical sepsis, diarrhea and abdominal pain. The biliary tract, lung and soft tissue were other primary sites of infection. Nosocomial infection occurred in 5 patients (38%). Cross-infection was not seen. Contact with fresh water or fish was observed in only 2 patients (15%). The majority of cases occurred in the warmer months of the year. The overall mortality was 46%. All isolates of Aeromonas species were resistant to ampicillin 8 mg/L. Ten isolates were resistant to tobramycin 1 mg/L, and 3 to tobramycin 4 mg/L. In contrast, 3 isolates were resistant to gentamicin 1 mg/L, and none to 4 mg/L. The isolates showed a varied pattern of resistance to other antibiotics tested, but all were susceptible to piperacillin 64 mg/L, imipenem 4 mg/L, ciprofloxacin 1 mg/L, and amikacin 16 mg/L.

Neutropenic enterocolitis, also known as typhlitis or ileocecal syndrome, is a recognized complication of the treatment of hematologic malignancies and usually is fatal. The pathologic findings consist of bowel-wall ulcerations and necrosis with bacterial or fungal invasion. These findings are usually limited to the ileum, cecum, ascending colon, and appendix. The syndrome occurs in a select patient population who generally have 1) a hematologic malignancy, 2) neutropenia, 3) thrombocytopenia, 4) a recent course of chemotherapy, and 5) a recent course of antibiotics. This syndrome also can arise spontaneously in patients with aplastic anemia or cyclic neutropenia. The clinical presentation consists of a high fever and right-sided abdominal pain with evidence of peritoneal irritation. Recommended therapy is right hemicolectomy.

A case of intestinovesical fistula secondary to leukemic infiltration is described. The patient was known to have chronic lymphocytic leukemia and had been receiving chemotherapy fo ten months. She presented complaining of nausea, vomiting and vague abdominal pain. She initially denied genitourinary tract symptoms, although admitting urinalysis revealed pyuria, hematuria and bacteriuria. Urine cultures repeatedly grew E. coli despite broad spectrum antibiotic therapy. She eventually developed fecalant material in her urine and pneumaturia. Cystoscopy revealed a fistulous tract. At surgery an ileovesical fistula was found and histopathology showed lymphocytic leukemic infiltration. Intestinovesical fistulas are uncommon. Congenital, traumatic, inflammatory and solid neoplastic etiologies are well established in the literature. No previous cases have been attributed to hematologic malignancies. Since higher remission rates and longer periods of remission are being achieved with chemotherapy, and since fistula symptomatology may present quite subtly, awareness of this association may expedite diagnosis.

A 64-year-old man presented with a history of four days of lower abdominal pain and 12 hours of cutaneous discoloration, bullae formation, and swelling of the soft tissues of abdominal wall and right thigh. Myonecrosis of abdominal wall and an adenocarcinoma of the cecum were found at operation. Cultures of blood and fluid from the bullae yielded Clostridium septicum. Nontraumatic clostridial myonecrosis is a fulminant, usually fatal disease that is most often the result of bacteremia from an occult gastrointestinal lesion. Ulceration of the colon or terminal ileum is the most common predisposing condition, and is usually due to gastrointestinal or hematological malignancy. Patients often present with nonspecific complaints, including pain at the affected site and fever. The disease progresses rapidly to include bronze discoloration, edema, and hemorrhagic bullous lesions of the skin, subcutaneous emphysema, and myonecrosis. Presumptive diagnosis often can be made by Gram stain of the bullous fluid that reveals gram-positive bacilli and a paucity of leukocytes. Favorable outcome depends on prompt institution of appropriate antimicrobial therapy and surgical debridement of involved soft tissues, as well as correction of the underlying disorder. This disease should be considered to be a medical-surgical emergency.

We retrospectively studied 343 consecutive patients treated between 1979 and 1992. Ninety patients whose stool was not examined were excluded. Fifty-three patients with strongyloidiasis were compared with 200 controls with regard to outcomes and the following characteristics: age, sex, underlying disease, use of corticosteroids, abdominal pain, diarrhea, fever, pulmonary symptoms, and eosinophilia. Patients with strongyloidiasis more commonly had eosinophilia (P = .01) and fever (P = .03). There was a single but fatal case of the disseminated disease syndrome (1.9% of patients with strongyloidiasis). In multiple logistic regression analysis, the factors predictive for strongyloidiasis were schistosomiasis (odds ratio [OR], 6.58), ascariasis (OR, 2.78), and the use of steroids (OR, 2.29). Strongyloidiasis was highly prevalent among patients with hematologic malignancies in Brazil. Occurrence of the disseminated disease syndrome seems to be unusual.

The effect of Blastocystis hominis (B. hominis) in both immunocompetent and immunocompromised subjects has been the subject of debate in recent years, mostly in response to its unknown pathogenicity and frequency of occurrence. We performed a non-randomised, open labelled, single institute study in our hospital in order to investigate the clinical significance and frequency of B. hominis in patients suffering from hematological malignancy (HM) who displayed symptoms of gastrointestinal diseases during the period of chemotherapy-induced neutropenia. The presence and potential role of other intestinal inclusive of parasites were also studied. At least 3 stool samples from each of 206 HM patients with gastrointestinal complaints (the HM group) were studied. These were compared with stool samples from a control group of 200 patients without HM who were also suffering from gastrointestinal complaints. Samples were studied with saline-lugol, formalin-ether, and trichome staining methods. Groups were comparable in terms of gender, age and type of gastrointestinal complaints. In the HM group, the most common parasite was B. hominis. In this group, 23 patients (13%) had B. hominis, while in the control group only 2 patients (1%) had B. hominis. This difference was statistically significant (P < 0.05). Symptoms were non-specific for B. hominis or other parasites in the HM group. The predominant symptoms in both groups were abdominal pain (87-89.5%), diarrhea (70-89.5%), and flatulence (74-68.4%). Although all patients with HM were symptom-free at the end of treatment with oral metranidazol (1,500 mg per day for 10 days) 2 patients with HM had positive stool samples containing an insignificant number of parasites (< 5 cells per field). In conclusion, it appears that B. hominis is not rare and should be considered in patients with HM who have gastrointestinal complaints while being treated with chemotherapy. Furthermore, metranidazol appears to be effective in treating B. hominis infection.

Mesenteric panniculitis is a rare disease of the bowel mesentery, characterized by tumor-like infiltration by chronic inflammatory cells, fat necrosis, and fibrosis. Reported cases cited clinical presentation ranging from abdominal pain to fever of unknown origin, the majority of which were idiopathic and associated with a benign prognosis. We report the case of a 43-yr-old male who presented with malaise, weight loss, microcytic anemia, and a high erythrocyte sedimentation rate. Radiographic and histological investigations revealed typical features of mesenteric panniculitis. Initial treatment with high-dose oral prednisolone led to rapid and complete resolution of symptomatology, radiographic, and laboratory anomalies. Within 6 months, the patient presented again with anemia, renal failure, and hypercalcemia. A diagnosis of IgA kappa chain myeloma was made. Despite chemotherapy and restoration of normocalcemia, he died from refractory pulmonary edema. This is the first report of a hematological malignancy initially presenting with features of mesenteric panniculitis culminating in an aggressive course and a fatal outcome.

Neutropenic enteritis is a septic or inflammatory disease of the colon. It is usually encountered in patients with hematological malignancy who have undergone chemotherapy, and it presents as fever, diarrhea, and abdominal pain, although the symptoms are not always specific. The diagnostic features of neutropenic enteritis revealed by barium enema, CT and ultrasonography have been reported previously. Here we report 4 cases of neutropenic enteritis in which ultrasound was used for diagnosis, and also for monitoring the clinical course of the disease. Because neutropenic enteritis is rapidly progressive, early diagnosis and therapeutic intervention are required. We believe that ultrasonography is a useful method for examining patients with neutropenic enteritis, being noninvasive, mobile, and providing rapid results in real time, thus aiding early diagnosis and clinical follow-up.

Philadelphia chromosome negative and bcr/abl negative chronic myeloid leukaemia (CML) is an uncommon atypical CML. We describe a patient with this disorder who experienced an acute blastic transformation that resulted in rapid splenic enlargement and subsequent atraumatic splenic rupture. Clinically, spontaneous splenic rupture may be a difficult diagnosis to make and this case highlights the importance of considering atraumatic splenic rupture as a cause for unexplained abdominal pain in a patient with a haematological malignancy.
