Twenty five consecutive patients with fever of unknown origin (FUO) who underwent diagnostic laparatomy (DL) are reviewed. There were 14 females and 11 males, with a mean age of 34 years. The main symptoms and signs besides fever were malaise, weight loss, varied abdominal complaints, peripheral lymph nodes enlargement, hepatomegaly and splenomegaly. The main laboratory abnormalities were: anemia, leukocytosis, and mild alterations in liver function tests. CT scan was performed in 14 patients: hepatomegaly, splenomegaly and or retroperitoneal nodes were found in 10 of them. During laparotomy, an extensive exploration of intra-abdominal organs was performed, taking multiple biopsies for histopathologic and microbiologic analysis. Splenectomy was performed in 17 patients, prophylactic appendectomy in four, and cholecistectomy in one. Laparotomy was useful to establish a diagnosis in 64 percent of cases. The most frequently diagnosed pathologies were lymphoma and tuberculosis. Postoperative morbidity was 12% and mortality was 4%. Mean follow-up was 29 months. When preoperative data were analyzed, no predictive factors were found for a laparotomy with diagnostic success. It is concluded that DL is a useful last-step procedure in the diagnostic work-up for patients with FUO.

The clinical and pathological findings of Babesia infection in 32 dogs in northern Australia are presented. Eleven different breed types were represented from 6 localities in north Queensland and one locality in northern Western Australia. Twenty three (72%) were males. Babesia-infected dogs were grouped by the degree of haematological disturbance and clinical severity: Acute babesiosis (25/32), all pups with severe haemolytic anaemia; subclinical carriers (5/32) with non-specific malaise, characterised haematologically by a normal erythrogram but marked leucopenia; chronic anaemia, observed in 2 adult dogs. Pups were azotaemic (serum urea greater than 6.6 mmol/l) and had elevated serum bilirubin levels (20.8 to 48.5 mmol/l). Total serum protein was usually within the normal range. Pups that died were also hypoglycaemic and severely hyperkalaemic (K+ greater than 10 mmol/l). Low parasitaemias in routine blood smears complicated diagnosis but smears made from ear or toe capillaries, or after haematocrit concentration, greatly enhanced finding parasitised cells. At necropsy, pallor and jaundice were the most consistent observations. Haemoglobinuric nephrosis, an active reticulo-endothelial system and capillaries packed with large numbers of infected erythrocytes were the main histopathological findings. A combination of imidocarb dipropionate at 5 mg/kg body weight, given intramuscularly, with fluid therapy and blood transfusion was the most successful treatment.

Increasing rates of human immunodeficiency virus (HIV) related tuberculosis have been noted and recently the clinical importance of the disease has been mentioned. The diagnosis of tuberculosis is more difficult in those patients with HIV seropositive than those with seronegative, because those with seropositive have atypical clinical features. A 29-year-old male, who was infected with HIV heterosexually in Central Africa in 1986, was admitted to our hospital with a history of general malaise and weight loss in April, 1989. Laboratory and physical examinations revealed anemia, thrombocytopenia, the elevation of LDH, and giant intraabdominal lymphadenopathies, suspecting malignant lymphoma. Mycobacterium was isolated from the sputa in April and was confirmed as M. tuberculosis using a DNA probe in May, 1989. Clinical symptoms including giant lymphadenopathies and laboratory abnormalities improved with antituberculosis therapy. Development of a rapid method for the diagnosis of tuberculosis was warranted in this case.

We report the cases of ten construction workers who developed acute lead intoxication while repairing a bridge in Louisiana. All but one patient received a five-day course of edetate calcium disodium (calcium EDTA) chelation therapy; one patient received five doses instead of five days of treatment. Calcium EDTA 25 mg/kg q12h was administered for ten consecutive doses by intravenous infusion over two hours. Each dose was diluted in NaCl 0.9% 500 mL. No adverse drug effects were observed during treatment. The posttreatment mean whole blood lead (PbB) concentration was significantly reduced compared with the pretreatment mean PbB (1.48 +/- 0.70 vs. 3.8 +/- 1.68 mumol/L; p = 0.0012, Student's paired t-test). This indicates that the body lead burden of these patients was effectively reduced with calcium EDTA. Eight patients had complaints on admission that were suggestive of lead intoxication. These included malaise, numbness of the extremities, arthralgia, myalgia, abdominal discomfort, sleep disturbance, and lower back pain. Patients had no complaints on discharge. Eight patients had mild anemia that was consistent with acute lead intoxication (mean pretreatment hemoglobin (+/- SD), 128.6(+/- 17.2 g/L), but calcium EDTA therapy did not appear to effect any change in the pretreatment hemoglobin values. The Occupational Safety and Health Administration (OSHA) lead standard requires that manufacturers provide employees at risk for occupational lead exposures with proper respirators and medical surveillance to prevent lead intoxication. The construction industry is exempted from these standards except in Maryland. We believe that amendment of the OSHA lead standards, to provide specific lead regulation of the construction industry, would be helpful in preventing similar cases of occupational lead intoxication.

A non-randomized study was carried out in the Free University Hospital, Amsterdam, to investigate the (hematologic) toxicity and antitumor response of patients with advanced breast cancer treated with intensive chemotherapy in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF). Of 11 patients with an inoperable or metastasized breast cancer, 5 were treated with doxorubicin 75 mg/m2 + cyclophosphamide 750 mg/m2 intravenously every 3 weeks and 6 patients with 90 and 1000 mg/m2 respectively. When in a preceding cycle a significant hematologic toxicity was observed, this patient was treated in the subsequent cycle with the same dose of chemotherapy in combination with GM-CSF 250 micrograms/m2/day from day 2-12 as a continuous infusion. Bone marrow depression was diminished in the presence of GM-CSF. This was apparent from a milder decline of the number of neutrophilic granulocytes, reduction of the neutropenic period and a more rapid recovery of the neutrophil number. A transient eosinophilia and a mild monocytosis were also observed. GM-CSF did not improve erythrocyte and thrombocyte counts. The efficacy of GM-CSF was less pronounced in the group of patients with the highest dose of chemotherapy. GM-CSF was associated with malaise, fever and a small decrease of blood pressure, which in combination with a frequently occurring anemia and the side-effects of high dose chemotherapy, resulted in a substantial toxicity. In 9/11 patients an objective tumor regression was noted. GM-CSF stimulated the recovery of granulocytes after intensive chemotherapy. Treatment of a small group of patients with advanced breast cancer with intensive chemotherapy resulted in a high antitumor response.

1. Combined chronic lead and arsenic poisoning was diagnosed in a 33-year-old Korean woman following consumption of a Korean herbal medicine prescribed for haemorrhoids. 2. The patient had malaise, severe difficulty walking, arthralgia, oedema and abdominal pain with diarrhoea. 3. Investigation showed anaemia with basophilic stippling, fragmentation and a raised reticulocyte count. 4. Raised blood and urine lead levels and urine arsenic levels were found. 5. Analysis of the herbal medicine revealed a high lead and arsenic content. 6. Treatment with the newer chelating agent 2,3-dimercaptosuccinic acid was successful, with no detectable side-effects.

Immunotherapy with interleukin (IL)-2 possesses great potential in the treatment of immune-mediated diseases and cancers. However, only a few reports on a small number of children have appeared in the literature. From March 1988 to March 1989, 11 children and adolescents were treated with IL-2. They included 1 patient with hepatocellular carcinoma, 1 with hepatoblastoma, 6 with childhood atopic dermatitis, and 3 with juvenile rheumatoid arthritis. The dosages ranged from 10,000 to 50,000 U/kg every 8 hours by intravenous drip. The following side effects were observed: anorexia, fever, and chillness (100%), general malaise (82%), irritability (64%), diarrhea (100%), nausea and vomiting (73%), weight gain (82%), edema (82%), abdominal distension (73%), oliguria (82%), cough (91%), dyspnea (27%), pleural effusion (40%), hypotension (82%), skin eruption (82%), oral ulcer (18%), enlarged liver (73%) liver function abnormalities (82%), renal function impairment (36%), electrolyte imbalance (73%), anemia (91%), thrombocytopenia (54%), leukopenia (18%), and eosinophilia (73%). Immunologically, numbers of natural killer cells were increased and natural killer and lymphokine-activated killer cell activities were augmented after IL-2 treatment. There was a tendency for serum levels of IL-2 and receptor IL-2 to decrease, especially in patients with atopic eczema. Ten patients (91%) completed one course (9 to 12 days) of therapy, and the remaining patient interrupted the treatment because of intolerable adverse effects. Clinically, complete remission for 3 months was obtained in 1 juvenile rheumatoid arthritis patient, transient improvement (2 to 6 weeks) in all atopic dermatitis patients, minor response in the hepatoblastoma patient, and no response in the patient with hepatocellular carcinoma.

A 72-year-old man was admitted to our hospital because of general malaise. The peripheral blood showed pancytopenia (WBC 800/microliters, RBC 970,000/microliters, Plt 95,000/microliters). The bone marrow smear revealed morphological abnormalities in three lineage without increase in blasts. He was diagnosed as having myelodysplastic syndrome (MDS). He was treated with recombinant human granulocyte colony-stimulating factor (rhG-CSF) for leukopenia, and with washed RBC transfusions for anemia. Eight months after diagnosis of MDS, blastic cells increased in peripheral blood and bone marrow showing overt leukemic state. He died of pneumonia. An autopsy revealed that atypical megakaryocytes increased in bone marrow and infiltrated into the spleen and liver. This case suggests that not only blasts but also megakaryocytes infiltrate into extramedullary organs in some cases of MDS.

The clinical and investigative features of 102 episodes of infective endocarditis were analysed retrospectively. The most frequent presenting symptoms (malaise, fever, sweats, myalgia, weight loss) were non-specific. Fever, cardiac murmur, tachycardia, vascular phenomena and a change in mental state were the most common physical signs at admission. Anaemia was present in half the episodes and renal and liver dysfunction in about one-third. Streptococci (61) and staphylococci (31) were the causative organisms in all but 10 episodes. The commonest predisposing factors were underlying cardiac disease (52 per cent) and a preceding focus of infection (14.6 per cent). Left ventricular failure (33 per cent) and focal neurological disease (29 per cent) occurred frequently. Valvular surgery was performed in 20 episodes, with two in-hospital deaths. Overall hospital mortality was 27.5 per cent and death was most commonly neurological (11/28). A higher mortality was associated with elevated total white blood count, microscopic haematuria, renal or liver dysfunction at admission, S. aureus endocarditis, the development of left ventricular failure or focal neurological disease, age greater than or equal to 60 years and persistence of fever after one week of antibiotic therapy. The absence of both renal dysfunction at admission and subsequent microscopic haematuria identified a group with a very low hospital mortality (4.7 per cent). The three-year mortality of the entire group was 43.5 per cent.

The clinical course of 103 patients (50 males, 53 females; median age 59 years) with idiopathic myelofibrosis (IMF) seen at our hospital between 1967 and 1986 was analyzed retrospectively. Common symptoms and signs at the time of diagnosis were: myelofibrosis (96%), splenomegaly (84%), anemia (81%), osteosclerosis (45%), malaise (41%) and leukocytosis (41%). It was possible to follow the majority of patients without treatment or with transfusion therapy only for prolonged periods of time. The use of cytostatic drugs and radiotherapy was restricted as much as possible. Probably due to this treatment strategy the incidence of acute leukemia was low (5%). Major thromboembolic complications were seen in 19% of the patients. Median survival of the patients was 4.3 years. The prognostic influence of several disease parameters determined at the time of diagnosis was tested: age, sex, leukocytes, platelets, hemoglobin, reticulocytes, LDH, ANP-score, spleen size and percentage of peripheral blood blasts + promyelocytes had no significant influence on the length of survival. Osteosclerosis, a presumed sign of advanced disease, was not correlated with survival either.
