We have performed a randomized, cross over study in 22 children suffering from acute leukaemia, who underwent repeated anaesthesia for bone marrow aspiration and lumbar puncture. For their first anaesthetic, the children (aged 3-10 years old) received, either a thiopentone/isoflurane anaesthetic or intravenous propofol, both supplemented with nitrous oxide. On a second occasion they received the alternative technique. Of those children receiving thiopentone/isoflurane, 32% had significant coughing during anaesthesia, two progressing to laryngospasm requiring 100% oxygen. None of the patients receiving propofol had a respiratory disturbance (P = 0.016). 68% of the children preferred the propofol anaesthetic. Only one child in the thiopentone/isoflurane group preferred this technique. Twenty-seven per cent had no preference. There was no significant difference in length of anaesthetic time (P = 0.07) or the time taken for recovery (P = 0.17) between the two groups. There was a large individual variation in propofol requirements and movement was common during stimulation of patients in this group, though this did not adversely affect the surgical procedure.

A retrospective study of 37 patients with haematological malignancy (21 acute myeloid leukaemia, 11 acute lymphoid leukaemia, two lymphoma, two hairy cell leukaemia, one Hodgkin's disease) and histologically documented mucormycosis was conducted to evaluate the clinical characteristics and ascertain the factors which influenced the outcome from mycotic infection. Patients were admitted to 18 haematology divisions in tertiary care or university hospitals in Italy between 1987 and 1995. Fever, thoracic pain, dyspnoea and cough were the most frequent presenting symptoms. At the onset, 89% patients were neutropenic (neutrophil counts < 0.5 x 10(9)/l) with a median duration of previous neutropenia of 14 d (range 6-60). The most frequent sites of infection were lungs (81%), CNS (27%), sinus (16%), liver (16%) and orbital space (10%). Only three patients were asymptomatic. A correct in vivo diagnosis was made in only 13 (35%) patients. When performed, thoracic and cranial CT scan were the most useful diagnostic investigations. Despite the fact that 26 febrile patients were treated with empirical antifungal treatment, 28 of the 37 patients (76%) died from fungal infection at a median time of 17 d from the onset of clinical symptoms. Nine patients were cured by antifungal therapy plus, in five cases, radical surgery procedures. An analysis of factors influencing outcome demonstrated that the resolution of chemotherapy-induced neutropenia and prolonged treatment with amphotericin B and, if feasible, radical surgical debridement treatment, were significantly correlated with recovery from infection. Mucormycosis, a rare filamentous fungal infection that occurs most frequently in neutropenic acute leukaemia patients, is characterized by a high mortality rate. Extensive and aggressive diagnostic and therapeutic procedures are essential to improve the prognosis in these patients.

A 31-year-old male was diagnosed as having chronic myelogenous leukaemia and has been treated with hydroxyurea and interferon-alpha since February 1995. After 16 months, he complained of low-grade fever and a cough. Bilateral hilar lymph node enlargement was detected on the chest X-ray film and multiple subcutaneous erythematous nodules appeared. A skin biopsy revealed subcutaneous sarcoid granuloma. Two months after the cessation of interferon therapy, the subcutaneous nodules and the hilar lymph node enlargement resolved. It is possible that continuous interferon administration can promote granuloma formation in sarcoidosis by activating T cells and macrophages.

A 48-year-old woman was admitted to our hospital with high fever, chills, cough, and exertional dyspnea. On admission, the chest roentgenogram and computed tomography scan showed bilateral alveolar infiltration in the middle and lower lung fields. Microscopic examination of the bronchial lavage fluid showed flower cells typical for adult T-cell leukemia (ATL) and cysts of Pneumocystis carinii, and Legionella pneumophila serogroup 1 grew on buffered charcoal yeast extract (BCYE)-alpha agar. The patient was successfully treated with antibiotics including trimethoprim/sulfamethoxazole, erythromycin, and sparfloxacin. Remission of ATL was achieved after three courses of antileukemic chemotherapy. Mixed infection of opportunistic pathogens should be considered in patients with ATL.

We report on a primary mediastinal large B-cell lymphoma with aberrant expression of beta-human chorionic gonadotropin (beta-hCG). The patient, a 33-year-old man, had cough, dyspnea, fever, superior vena cava syndrome, and a mediastinal bulky tumor. A biopsy showed that the latter was characterized by large cells, sclerosis, and compartmentalization. The neoplastic elements expressed CD45, CD20, CD79a and, partially, CD30, whereas they were negative for CD3, epithelial membrane antigen and cytokeratins. Surprisingly, they displayed a clear-cut positivity for beta-hCG. The remaining oncofetal markers applied (PLAP and alpha1-fetoprotein) were negative. Electron microscopy demonstrated the presence of numerous nuclear pockets and the lack of intercellular junctions. DNA analysis by polymerase chain reaction showed clonal rearrangement of Ig heavy-chain genes. The patient responded promptly to the administration of MACOP-B. To the best of our knowledge, this is the first example of B-cell lymphoma showing positivity for beta-hCG; a similar aberrant expression was previously observed only in three Japanese patients with human T-cell lymphotropic virus type I+ adult T-cell lymphoma/leukemia. Because primary mediastinal large B-cell lymphoma has in the past been frequently confused with germ cell tumors, pathologists should be aware of possible beta-hCG expression by lymphomatous cells to avoid the risk of misdiagnosis.

A 54-year-old woman was admitted to Juntendo Izunagaoka Hospital on Aug. 29, 1998, after experiencing cough and fever for 19 days. Chest X-ray films disclosed infiltrates in the left lung field. The abnormal lung shadows progressed despite antibiotic therapy, and enlargement of superficial lymph nodes and hepatosplenomegaly developed. Peripheral blood examination disclosed cleaved lymphoid cells without granular cytoplasm. Anti-HTLV-I antibody titer was x320, and the monoclonal integration of HTLV-I provirus was confirmed by Southern blot analysis. Surface marker analysis of lymph node cells was positive for CD2, CD3, CD4, CD5, CD56, and HLA-DR. The above results yielded a diagnosis of adult T-cell leukemia. LSG-4 therapy alleviated the lung infiltrations and dyspnea. This case was considered unusual because of the expression of the natural killer cell marker CD56 on leukemic cells and the presentation of abnormal lung shadows possibly due to leukemic cell infiltration.

The purpose of this study was to determine symptom prevalence, characteristics, and distress in children with cancer. The Memorial Symptom Assessment Scale (MSAS) 10-18, a 30-item patient-rated instrument adapted from a previously validated adult version, provided multidimensional information about the symptoms experienced by children with cancer. This instrument was administered to 160 children with cancer aged 10-18 (45 inpatients, 115 outpatients). To confirm the instrument's reliability and validity, additional data about symptoms were collected from both the parents and the medical charts, and retesting was performed on a subgroup of inpatients. Patients could easily complete the scale in a mean of 11 minutes. The analyses supported the reliability and validity of the MSAS 10-18 subscale scores as measures of physical, psychological, and global symptom distress, respectively. Symptom prevalence ranged from 49.7% for lack of energy to 6.3% for problems with urination. The mean (+/- SD) number of symptoms per inpatient was 12.7 +/- 4.9 (range, 4-26), significantly more than the mean 6.5 +/- 5.7 (range, 0-28) symptoms per outpatient. Patients who had recently received chemotherapy had significantly more symptoms than patients who had not received chemotherapy for more than 4 months (11.6 +/- 6.0 vs. 5. 2 +/- 5.1), and those patients with solid tumors had significantly more symptoms than patients with either leukemia, lymphoma, or central nervous system malignancies (9.9 +/- 7.0 vs. 6.8 +/- 5.5 vs. 6.8 +/- 5.0 vs. 8.0 +/- 6.1). The most common symptoms (prevalence > 35%) were lack of energy, pain, drowsiness, nausea, cough, lack of appetite, and psychological symptoms (feeling sad, feeling nervous, worrying, feeling irritable). Of the symptoms with prevalence rates > 35%, those that caused high distress in more than one-third of patients were feeling sad, pain, nausea, lack of appetite, and feeling irritable. Subscale scores demonstrated large variability in symptom distress and could identify subgroups with high distress. The prevalence, characteristics, and distress associated with physical and psychological symptoms could be quantified in older children with cancer. The data confirm a high prevalence of symptoms overall and the existence of subgroups with high distress associated with one or multiple symptoms. Symptom distress is relatively higher among inpatients, children with solid tumors, and children who are undergoing antineoplastic treatment. Systematic symptom assessment may be useful in future epidemiological studies of symptoms and in clinical chemotherapeutic trials. Symptom epidemiology may also provide a focus for future clinical trials related to symptom management in children with cancer.

We describe two patients with acute leukaemia who died of massive haemoptysis caused by invasive pulmonary aspergillosis (IPA). The fatal event occurred during the period of bone marrow remission which followed chemotherapy-induced neutropenia. This is a rare complication. We were able to find additional 17 similar cases in the English literature, which we review. Clinically, the picture consisted of unremitting fever with profound and prolonged neutropenia, cough and dyspnoea. Both our patients were treated with broad-spectrum antibiotics, fluconazole and amphotericin B. An upper lobe infiltrate in one case, and a progressive pleural effusion in the other, were late findings on chest radiographs during the period of bone marrow recovery. Both patients succumbed to sudden massive haemoptysis during the period of bone marrow and clinical improvement. In conclusion, patients with acute non-lymphoid leukaemia are at significant risk for IPA-induced fatal haemoptysis during bone marrow and clinical remission. A high index of suspicion should be sustained throughout the entire clinical course. In view of the potential fatal outcome, aggressive diagnostic and treatment efforts are mandatory.

Disseminated Fusarium infection in an immunocompromised host is intractable and results in high mortality. We provide the first full case report on successful treatment of a disseminated Fusarium infection in an infant. The 6-month-old infant, whose family raised livestock, had infantile leukemia. During the neutropenic period after intensive chemotherapy, vomiting, diarrhea, fever, subcutaneous nodes, and coughing appeared. Pneumonia was diagnosed, and Fusarium moniliforme was isolated from blood culture. A central venous catheter was removed. Granulocyte colony-stimulating factor (G-CSF) and amphotericin B (AMPH-B) (total dose, 65 mg/kg) were administered continuously for 8 weeks. The infection was resolved according to improvement of clinical and laboratory findings, and intensive chemotherapy was restarted for the leukemia. Cord blood stem cell transplantation from an unrelated donor was performed. The Fusarium infection did not recur, but after transplantation, leukemia relapsed. Treatment of neutrophils using G-CSF, AMPH-B, and local treatment induced resolution of the disseminated Fusarium infection in this immunocompromised host with malignancy. We suggest caution for patients living in an environment conducive to the development of Fusarium infection because of the particular risk of infection.

It is extremely important to look for tropical and other exotic diseases in travellers who return with illness or become ill after travelling. Especially tropical diseases and exotic infectious diseases have to be excluded because of their possible fatal outcome. On the other hand, many travellers return with 'common' not-exotic illnesses not related to their journey. When in such cases attention is only given to exotic causes of their illness, diagnosis can be delayed which may be harmful. This was the case in 5 patients: a woman aged 44 years who suffered for months from bloody diarrhoea since her return from Brasil, due to a rectal adenocarcinoma, a 61-year-old man with diarrhoea upon returning from Egypt, who had hairy-cell leukaemia, a 17-year-old boy who developed a ketoacidotic diabetic crisis whilst on a journey in Uganda, but in whose case the first thoughts went to malaria, a 50-year-old man who suffered from throat pain since a journey through East Africa, during which he contracted a flu-like disease, and in whom Kahler's disease was diagnosed, and 69-year-old man suffering from recurrent fever and cough, in whom a radiological lesion was observed in the thorax which proved to be part of Wegener's disease.
