Typhlitis is a necrotizing inflammation of the cecum usually found in acute leukemia patients on chemotherapy in the setting of agranulocytosis. We describe five cases of typhlitis, characterized by fever, abdominal pain, abdominal tenderness and watery diarrhea, occurring during periods of neutropenia. In 4 cases, sonography showed thickening of the cecum wall. Ultrasound appears to offer an easy noninvasive method of diagnosing this potential lethal disease. Four patients were treated successfully with broad-spectrum antibiotics and bowel rest. There was 1 death resulting from septic complication.

A 44-year-old man received high-dose chemotherapy with carboplatin, etoposide and cyclophosphamide followed by autologous peripheral-blood stem-cell transplantation for treatment of refractory nonseminomatous testicular cancer (seminoma plus choriocarcinoma). The patient developed fever, watery diarrhea and abdominal pain at 10 days after the initiation of high-dose chemotherapy. Radiological examinations revealed adynamic ileus with thickened colon and small bowel wall and increasing ascites over the next 3 days. The patient subsequently suffered from disseminated intravascular coagulation, renal failure and hyperbilirubinemia despite systemic antibiotic therapy. Intensive medical care could barely avoid the fatal outcome. Neutropenic colitis has been recognized as a complication of acute leukemia or aplastic anemia. The present case indicates that this serious gastrointestinal complication can occur under profound neutropenic conditions induced by intensive chemotherapy for solid cancer.

Cryptosporidium was detected in 21 (3.8%) individual stool samples collected from 553 pediatric patients hospitalized in our center employing a Telemann concentration technique (formalin-ether-centrifugation) and stained with the modified Kinyoun method. The mean age of populations with Cryptosporidiosis (16 boys and 5 girls) was 11 months; 15 months for girls and 6.5 for boys. Ages of 81% of them were less than 19 months. Seventy-six per cent of patients lived on the outskirts of Buenos Aires and 71% lacked pretreated running water at home. In 62% of the cases parasitological diagnoses coincided with warm seasons. At diagnosis mucous (63%) or watery (36%) diarrhea was presented in 90% of the patients with a median of 5 (3-8) bowel movements per day. Fever was presented in 66% of patients while abdominal pain and vomits in 60% and 52%, respectively. The median time from hospitalization up to parasitologic diagnosis was 20 days. Concomitant diseases observed were malnutrition, acute leukemia, bronchiolitis, HIV infection, anemia, celiac disease, myelofibrosis, vitelline sac tumor, neutropenia, osteosarcoma and dehydration. Cryptosporidiosis in our environment seems to occur more frequently in children younger than 18 months of age; who present diarrhea; are immunodeficient; come from a low socioeconomical background; and who live in poor sanitary conditions with no potable running water.

Neutropenic enterocolitis is a necrotizing inflammatory process with intramural infection that occurs predominantly in neutropenic patients. This syndrome is most frequently observed after chemotherapy for hematologic and solid tissue malignancies, but it can also be observed in a number of other clinical settings as well. Neutropenic enterocolitis can be a rare presenting complication of acute leukemia. We report a case of acute lymphoblastic leukemia that presented with abdominal pain due to neutropenic enterocolitis. The diagnostic and treatment challenges associated with this manner of presentation are discussed.

Essential thrombocythemia and polycythemia vera are both chronic progressive myeloproliferative disorders of insidious onset. If the excessive production of red cells and/or platelets is controlled, patients with these disorders may have prolonged survival. However, the clinical course of these patients can be complicated by a variety of events, including thrombotic episodes, bleeding episodes, arthropathies, pruritus, weakness, weight loss, neurologic impairment, erythromelalgia, fever, abdominal pain, and the life-threatening consequences of progression to myelofibrosis and/or acute leukemia. Effective control of hematopoiesis by phlebotomy or a variety of therapeutic agents has resulted in a reduction or elimination of many of these clinical events, but has not altered the evolution to myelofibrosis or acute leukemia. Use of each of these therapeutic strategies is also associated with a range of adverse events. Monitoring overall survival or a reduction in the frequency of clinical events has previously served as a means of assessing the results of these therapeutic interventions. Quality-of-life instruments have not been applied in a systematic fashion to the evaluation of outcomes in patients with these chronic myeloproliferative disorders. Quality-of-life assessments evaluate not only the state of well-being of a patient that results from an assessment of the individual's ability to perform everyday activities, which are reflective of physical, psychological, and social well-being, but also patient satisfaction with the control of disease and/or treatment-related symptoms. Quality-of-life instruments have been used to assess the clinical course of patients suffering from a variety of disorders, ranging from cancer to renal failure to chronic fatigue syndrome. Information about quality-of-life outcomes can contribute to the evaluation of variations in dose and timing of administration of therapeutic agents. It is possible that the side effects of a particular therapy may outweigh the disease regression achieved with a particular therapy. In the future, quality-of-life instruments may prove useful in prospectively evaluating therapeutic end points in patients with essential thrombocythemia and polycythemia vera.

Acute leukemias with thrombocytosis have been recently linked with structural abnormalities of the short arm of chromosome 3. A 46-year-old man with a 2-month history of recurrent transient ischemic attacks and abdominal pain developed an ischemic left foot and a gangrenous toe as his initial symptoms. Platelet count was 3.5 x 10(6)/microL, and despite plateletpheresis, the patient required left-leg amputation. Pathologic examination was remarkable for arterial thrombosis in the absence of atherosclerotic lesions. A diagnosis of acute myeloid leukemia with a novel translocation between chromosomes 3q21, 16, and 7 was made. Induction therapy was unsuccessful, and the patient died of overwhelming sepsis within 5 weeks of diagnosis. The striking features of this case were extreme symptomatic thrombocytosis, peripheral gangrene without atherosclerosis, and a novel three-way chromosomal translocation involving chromosome 3q21.

Hepatosplenic microabscesses secondary to invasion by various organisms may result in life-threatening conditions, especially in patients with cancer. Whether these patients should continue ongoing cytotoxic therapy, which might result in neutropenia, with the risk of progressive abscess formation or fungemia, remains a dilemma. We report five cases of pediatric acute leukemia with hepatosplenic microabscesses in children aged 4 years to 18 years. These patients presented with prolonged fever and neutropenia after antineoplastic chemotherapy, followed by abdominal pain, hepatosplenomegaly and hepatic dysfunction. Abdominal ultrasound and computed tomography (CT) or magnetic resonance imaging (MRI) demonstrated multiple small lesions compatible with hepatosplenic candidiasis in all of the patients. Cultures, including blood or stool cultures, were positive in only two cases. Treatment with intravenous antifungal agents, including amphotericin B, liposomal amphotericin B, and/or fluconazole were successful in two cases. These two patients remained event-free and survived for more than 24 months (20 months and 22 months after infection was diagnosed). The duration of systemic antifungal medication administration ranged from 3 months to 22 months. The serial image examinations revealed drastic reductions in small residual lesions in the two patients who survived the longest. The major issues for these patients were how long the antifungal therapy should be administered for, and how to select the optimal drug and dosage to avoid hepatic and renal toxicity. Among our patients, alternative therapy with amphotericin B, liposomal amphotericin B, and fluconazole was used according to the patients' conditions, and the duration of antifungal therapy was determined by clinical manifestations and imaging study changes.

The purpose of this study was to investigate the initial clinical features and subsequent outcomes in patients with adult leukemia with typhlitis or neutropenic enterocolitis. A retrospective review of 10 episodes of neutropenic enterocolitis in nine patients (age range, 21-71 years) with acute leukemia from March 1, 1990, through February 28, 2002, was conducted. In clinical presentations, fever appears in all patients, followed by abdominal pain or tenderness (90%) and diarrhea (60%), respectively. In particular, three cases were coincidentally diagnosed as leukemia before any chemotherapy. The most common diagnostic modality used for the diagnosis of neutropenic enterocolitis was computed tomography (CT) scan (seven episodes). Medical treatments, including broad-spectrum antibiotics, bowel rest, and total parenteral nutrition, were applied to seven patients. Laparotomy with bowel resection was performed on two patients with bowel necrosis and severe peritonitis. Of all nine cases, six were fatal as a result of sepsis, a common complication of neutropenic enterocolitis. As the incidence of neutropenic enterocolitis increases in patients with acute leukemia, EPs should be alert and make an early diagnosis of this rapidly deteriorated and life-threatening disease.

Portal vein thrombosis (PVT) consists of two different entities: acute PVT and chronic PVT. Acute PVT usually presents as abdominal pain. When the thrombus extends to the mesenteric venous arches, intestinal infarction can occur. Chronic PVT is usually recognized after a fortuitous diagnosis of hypersplenism or portal hypertension, or when there are biliary symptoms related to portal cholangiopathy. Local risk factors for PVT, such as an abdominal inflammatory focus, can be identified in 30% of patients with acute PVT; 70% of patients with acute and chronic PVT have a general risk factor for PVT, most commonly myeloproliferative disease. Early initiation of anticoagulation therapy for acute PVT is associated with complete and partial success in 50% and 40% of patients, respectively. A minimum of 6 months' anticoagulation therapy is recommended for the treatment of acute PVT. For patients with either form of PVT, permanent anticoagulation therapy should be considered if they have a permanent risk factor. In patients with large varices, beta-adrenergic blockade or endoscopic therapy seems to prevent bleeding as a result of portal hypertension, even in patients on anticoagulation therapy. In patients with jaundice or recurrent biliary symptoms caused by cholangiopathy, insertion of a biliary endoprosthesis is the first treatment option. Overall, the long-term outcome for patients with PVT is good, but is jeopardized by cholangiopathy and transformation of underlying myeloproliferative disease into myelofibrosis or acute leukemia.

We report here on the clinical courses of three cases of acute appendicitis during a period of myelosuppression after chemotherapy for acute leukemia. The patients were two boys and one girl with a mean age 11 years (range, 10-12). Two of the patients had acute myeloid leukemia (AML) in subtypes M1 and M2, while the third had acute lymphoblostic leukemia of subtype L1 (FAB classification). All patients had clinical features of fever, abdominal pain, and elevations of C-reactive protein. However, the typical peritoneal signs were blunted and developed transiently in two cases. All patients were diagnosed as having appendicitis with abdominal computed tomography scan (CT), and proceeded to appendectomy. With perioperative support utilizing antibiotics, antifungal agents, blood components, and granulocyte-colony stimulating factor, surgical intervention was successfully performed, and all patients were able to undergo chemotherapy courses shortly after surgery. Histological examinations of the appendectomy specimens showed infiltration of most of the lymphoid cells and a few neutrophils in the wall of the appendix. Enhanced CT was useful in diagnosing appendicitis, which needs to be considered in cases presenting with clinical symptoms such as described here. Because of a high mortality rate after appendix perforation, immediate surgical intervention with sufficient perioperative support should be performed.
