The diagnostic findings of malignant histiocytosis (MH) were analysed in 12 consecutive patients in a single institution. Most patients presented with systemic symptoms and lymphadenopathy (92%), splenomegaly (100%) and hepatomegaly (67%). Neurologic symptoms were present in three patients, while involvement of other organs was present in five patients. The incidence of severe thrombocytopenia was 92% of anaemia 92% and of leucocytopenia 67%. Serum angiotensin converting enzyme, alpha 1-antitrypsin and lysozyme were independently increased in 6/9, 3/10 and 1/9 patients respectively. High serum levels of tumour necrosis factor (TNF) were present in 3/10 patients, while serum levels of interleukin-1 were normal in 10/10 patients. Histologic evidence of MH was obtained in all patients by repeated biopsies of involved tissues. Four patients died prior to treatment. Seven patients were treated with combination chemotherapy, consisting of CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) or MOPP (chloromethine, vincristine, procarbazine, prednisone), in some cases followed by non-cross-resistant second line chemotherapy, if no complete response was attained. The response rate of treated patients was 57%, and progression was observed in two patients. The median duration of response was 38 months. Three patients are alive without evidence of disease and off therapy (30+, 83+, 85+ months). Although MH is a potentially lethal disease, combination chemotherapy may offer a chance for cure in some patients.

The medical records of 222 patients with liver abscess at Siriraj Hospital from 1978 to 1985 were analysed. Amoebic abscess was three times more prevalent than pyogenic abscess. In both groups middle aged males were affected more often than others. The main clinical manifestations were fever, right upper quadrant pain and hepatomegaly. History of colitis in the past, marked leukocytosis, elevation of alkaline phosphatase and a single abscess confined to the right lobe were suggestive of amoebic liver abscess. The presence of concurrent abdominal infection, marked anemia and jaundice were associated with pyogenic abscess. Patients with pyogenic abscess developed complications more often and the case fatality rate was greater than patients with amoebic abscess. Most of the patients were successfully treated with a combination of antimicrobials and drainage.

The potential toxic interactions in F344 rats of the munitions compounds trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) were examined following their coadministration in the diet. Groups of 10 rats per sex received TNT at doses of 5 or 125 mg/kg/day, RDX at doses of 30, 100, or 300 mg/kg/day, and combinations thereof for 13 weeks. Thirty rats per sex served as controls. Toxicologic endpoints included clinical observations, body weight, food consumption, hematology, clinical chemistry, organ weights, and tissue morphology. The major toxic effects following dietary administration of TNT to rats included anemia, hypercholesterolemia, and hepatomegaly, splenomegaly, and testicular atrophy with their accompanying histologic lesions. RDX intoxication in rats included hypotriglyceridemia, behavioral changes, and mortality. Most of the toxic effects of these chemicals were partially antagonized following their coadministration.

In 1980, a 38-year-old man had remittent fever, swelling and arthralgia of the knee, ankle and wrist joints, as well as visual disturbance due to bilateral iritis. On his admission to our hospital, his laboratory data showed neutrophilia, normocytic normochromic anemia, hepatomegaly, hepatocellular damage, and a strongly positive RA test. All the microbiological examinations were negative. Thirty mg of prednisolone improved his symptoms and abnormal laboratory findings. Due to persistent mild arthralgia, he had continued to take 5-10 mg of prednisolone and analgesics until 1985 when he was readmitted to our hospital. In 1983, he began to complain of a steady pain around his left eye, and he sometimes had double vision. In 1985, he began to complain of decreasing left visual acuity and sensory disturbance in his left face in addition to pain in and around the eye. On his 2nd admission to our hospital, the neurological examination revealed involvement of the 2nd and 3rd cranial nerves and the 1st branch of the 5th cranial nerves of the left side. Laboratory data showed a positive RA test with RAHA titer at 1:320 and IgM at 216 mg/dl, but he had no joint deformities. The computed tomography (CT) of the brain demonstrated a high density mass of his left cavernous sinus extending to the left orbital apex. The prescription of the high dose of prednisolone (100 mg/day) relieved ophthalmic pain and improved visual acuity and neurological involvement within a week. Prednisolone was then gradually decreased to 10 mg. In 1986, he had partial and complex partial seizures.(ABSTRACT TRUNCATED AT 250 WORDS)

Liver involvement in typhoid fever is uncommon. Typhoid hepatitis is now being recognized as a definite entity. Over a period of 4 years, we have observed 10 cases (4.8%) of typhoid hepatitis out of 210 cases of typhoid fever. Jaundice, anaemia, hepatomegaly and abnormal biochemical tests were present in all cases. Liver biopsy was done in 8 cases and was found to be abnormal in 5. Two of the 10 cases of typhoid hepatitis died. Recognition of typhoid hepatitis is important since it has to be differentiated from other common ailments in the tropics such as viral, malarial or amoebic hepatitis. Early institution of specific therapy in cases of typhoid hepatitis carries a good prognosis.

Generally, individuals who are heterozygous to haemoglobin S (Hb AS) are asymptomatic and do not present any haematological or clinical manifestations. However, other associated genetic abnormalities may influence the presentation in Hb AS cases. This study was conducted on twenty children heterozygous for HB S who presented clinical manifestations similar to those of sickle cell anaemia. All these children had anaemia associated with several red cell morphological abnormalities. The white blood cell counts were elevated in all patients and differential count studies showed a substantial increase in lymphocytes and polymorphonuclear leucocytes in the majority of the cases. Forty-five per cent of the patients had associated alpha-thalassaemia, 60 per cent had beta-thalassaemia, 30 per cent had G-6-PD deficiency and 10 per cent had partial glutathione reductase deficiency. Pyruvate kinase activity was normal in all cases. Riboflavin deficiency was encountered in 30 per cent of the patients and iron deficiency in 15 per cent of these Hb S heterozygotes. The major clinical findings were splenomegaly, hepatomegaly, and vaso-occlusive crisis. The majority of the patients had received blood transfusions. The hand and foot syndrome was identified in three (15 per cent) of the patients. The haematological and clinical findings in these twenty Hb S heterozygotes are presented in this paper and the possible causes for these abnormalities are discussed.

A patient with multiple, pyogenic hepatic abscesses is described, and the pathophysiology, etiologies, clinical and laboratory manifestations, and management of the disease are reviewed. A 55-year-old man with a history of ethanol abuse and pancreatitis developed fever, chills, general malaise, and right upper quadrant abdominal pain two weeks before hospitalization. Baseline laboratory and hematology results included serum albumin concentration, 3.2 g/dL; serum alkaline phosphatase concentration, 239 mIU/mL; total serum bilirubin concentration, 1.3 mg/dL; white blood cell count, 18,400/cu mm; red blood cell count, 4.7 million/cu mm; hemoglobin, 12.5 g/dL; and hematocrit, 38.8%. Abdominal ultrasound showed echo-free cavities throughout the hepatic parenchyma; abdominal computed-tomography (CT) scan showed hepatomegaly and multiple radiolucent spaces. CT-guided needle aspiration of a hepatic mass yielded purulent material that grew Fusobacterium necrophorum under anaerobic conditions. On day 7, the patient was started on i.v. ampicillin sodium-sulbactam sodium. A CT scan two weeks later showed a reduction in the number and sizes of abscesses. The patient continued i.v. therapy for one month, then was discharged on a regimen of p.o. amoxicillin trihydrate-clavulanate potassium. Hepatic abscesses are either amebic or pyogenic; the latter usually has a higher mortality. The etiologies of pyogenic hepatic abscesses include ascending cholangitis, portal vein bacteremia, systemic bacteremia, extension from a contiguous focus of infection, and trauma. Diagnosis is difficult and relies highly on clinical suspicion. Clinical symptoms include hepatomegaly, fever, chills, and malaise. Abnormal laboratory values include leukocytosis, anemia, and hypoalbuminemia. The abscesses are frequently polymicrobial; Escherichia coli is the most commonly isolated species. CT is the best radiological technique for diagnosis.(ABSTRACT TRUNCATED AT 250 WORDS)

A 60-year-old man with primary splenic hemangiosarcoma (PSH) presented with weakness, weight loss, abdominal pain, and anemia. Physical examination revealed hepatomegaly, ascites, and firm, huge splenomegaly. Ultrasonography showed many nodular structures characterized by hypoechogenic and hyperechogenic areas. The patient also had portal hypertension, which was confirmed by physical findings and by measurement of portal vein pressure during operation. A liver-spleen scan using Tc-99m sulfur colloid and Tc-99m labeled heat denatured erythrocytes failed to demonstrate any splenic uptake, a reliable feature of functional asplenia. Although on a total body scan with Ga-67 citrate there was no splenic uptake, there was gallium uptake in the liver, where the presence of the metastatic lesion was histopathologically verified and confirmed by operation. There was also uptake in the middle zones of the lungs. Ga-67 citrate imaging appears to be helpful in the diagnosis of metastasis of PSH, and PSH can rarely cause portal hypertension.

A 22-year old male was admitted to Ashikaga Red Cross Hospital because of the progressing abdominal distension in May 1988. The physical examinations disclosed marked hepato-splenomegaly, lymphadenopathy and cachexic state. In the laboratory examinations, anemia, leukocytosis with left shift of nuclei and severe inflammatory reactions were found. Bone marrow aspirations were dry taps, and the biopsy showed myelofibrotic changes. Abdominal computed tomography and ultrasonography revealed a marked hepatomegaly and a giant splenomegaly with subcapsular hematoma. Philadelphia chromosome was negative and neutrophilic alkaline phosphatase score was slightly high. A little amount of peritoneal effusions was obtained and yielded S. aureus. A diagnosis of myelofibrosis with subcapsular hematoma due to spontaneous rupture of spleen and peritonitis of unknown cause was made. Operative indication was considered, but his family did not agree with it. Then conservative therapies for general conditions, those are, administrations of antibiotics and diuretics, and blood transfusions were taken. On the enlarged spleen, total irradiation was done. After the therapies, his spleen got smaller and hematoma was going to be absorbed. A rare case of myelofibrosis with splenic hematoma is reported and the conservative therapies were effective to this case.

Seventy-one Saudi and Yemeni Arabs with sickle cell anaemia from western Saudi Arabia aged between 1 1/2 and 42 years were studied. The mean steady state haemoglobin concentration of 8.1 g/dl was lower than that of 10.7 g/dl reported previously for sickle cell anaemia in eastern Saudi Arabia. The patients were divided into an SSLF group with fetal haemoglobin (HbF) of 10.0% or below (44 patients) and an SSHF group having HbF above 10.0% (27 patients). No significant differences were found in the haemoglobin concentrations, haematological indices and incidences of bone changes of the two groups. SSLF patients were significantly more prone to infections (P less than 0.01), however. Also, there was an overall high incidence of hepatomegaly (69.0%) and splenomegaly (54.9%) and hepatomegaly was significantly more common in the SSLF group (P less than 0.02). Many of the patients, even with HbF levels over 10.0%, did not follow a benign course and suffered from severe anaemia, infections of the respiratory and urinary tracts, bone pains and infarcts, or bossing of the skull. Rarer complications included hepatic crisis, chest syndrome, retinal haemorrhage, epistaxis and hemiplegia. It is therefore apparent that Saudi Arabian sickle cell anaemia, even in patients with raised haemoglobin F levels, may be as clinically severe as in African patients.
