This report reviews the manifestations in fifteen children of proved adenoviral pneumonia. Patients' ages ranged from 43 days to 4 years and 1 month. Twelve cases were younger than 2 years old. Adenoviral infections were proved by positive viral cultures or a four-fold increase of the complement fixation titer. Prolonged fever and cough were found in all cases. In 13 patients, respiratory distress occurred; 5 needed mechanical ventilation. Injected throats, conjunctivae and ear drums were common. Other clinical pictures included abdominal discomfort, hepatomegaly, skin rash, convulsion and bleeding tendency. Abnormal laboratory findings were mild anemia, leukopenia, thrombocytopenia, elevated erythrocyte sedimentation rate and C-reactive protein, impaired liver function test, and prolonged prothrombin time and partial thromboplastin time. Anemia (11 cases), leukopenia (7 cases) and elevated transaminases levels (7 cases) were more common than previously reported. All patients had para-hilar peribronchial infiltrates in chest roentgenography. Segmental atelectasis and compensated hyper-expansion were found frequently. Pleural effusion were noted in six of our cases. Air leak syndrome occurred in three patients who had received mechanical ventilation. Three of the 15 patients expired: one had a preceding measles infection, all had disseminated intravascular coagulopathy. For patients with antibiotic-resistant pneumonia, adenoviral studies should be done. Extrapulmonary manifestations, and some abnormal laboratory findings, i.e., mild anemia, leukopenia, impaired liver function are clues to adenoviral infections, while bleeding tendency can be regarded as a poor prognostic sign for children with adenoviral pneumonia.

For 2 years a 72-year-old man had suffered from nonspecific upper abdominal discomfort and hepatomegaly. The gamma-glutamate transaminase concentration was increased to 121 U/l, the erythrocyte sedimentation rate was 80 mm in the first hour. Histological examination of tissue from the enlarged liver (22 cm in the midclavicular line) revealed the diagnosis of amyloidosis. The gastric mucosa, duodenum and rectum were not involved. Two years later ascites developed; six months after this he was again hospitalized in hepatic coma. Now, for the first time, a type IgA-lambda paraprotein was demonstrated by serum immunoelectrophoresis. The patient died of slowly progressing anicteric liver failure after having been ill for a total of 4 1/2 years. At autopsy there were extensive amyloid deposits throughout the liver and spleen so that the structure of these organs was hardly recognizable. The amyloid deposits in the liver were restricted to the glomerular region, while there was no amyloid in the heart. Histochemical tests showed that the deposits were strongly positive to the anti-lambda antibody. This was thus a case of primary (AL-lambda) amyloidosis of the liver and spleen which had taken an unusually prolonged course, because the heart was not involved at all and the kidneys only slightly.

In this study we examined the clinical and laboratory findings of 80 in-patients. There is an important difference between sexes (p greater than 0.05). Comparison of ages showed that 7-30 age is more vulnerable than the older group. We found clinical symptoms of fever, chills, headache, abdominal pain, disturbances in bowel function, nausea, vomiting, anorexia, and lassitude in the first two weeks more frequently when compared with the 3rd, 4th, 5th weeks of illness (p less than 0.001). Where physical finding of rose spots, discordant pulse rate are important in the first two weeks (p less than 0.001). Abdominal discomfort is an important symptom both in the first two and in the last three weeks (% 40.3 and % 36 respectively). Hepatomegaly and splenomegaly, were found more frequently in the last three weeks. According to laboratory findings of anemia, leukopenia, increased erythrocyte sedimentation rate and positive blood and feces cultures there is no important difference between the first two and last three weeks (p greater than 0.05). Increase in polynuclear leucocytes is important for the first two weeks, and increase in lymphocytes is important in the last three weeks (p less than 0.001). Positivity of group agglutination tests is 57%, in the first two weeks and 83% in the last three weeks. This difference is found to be important.

Constrictive pericarditis is a slowly progressive disabling disease. The diagnosis is easily overlooked because of the striking extracardial signs and symptoms such as abdominal discomfort, general fatigue, cachexia, ascites and oedema. We describe 7 patients with these symptoms in whom the diagnosis was missed during 0.5-17 years. The decisive clue for correct diagnosis appeared to be the raised central venous pressure. This proves the importance of an accurate physical examination. Other findings were: ascites (7/7), hepatomegaly (7/7), oedema (6/7), narrow pulse pressure (less than or equal to 35 mmHg) (5/7), ECG abnormalities (7/7) and pericardial calcifications on the chest X-ray (5/7). In addition we found slightly raised liver enzymes and a protein-losing enteropathy leading to low serum protein levels. These abnormalities are all explained by the alterations in haemodynamics and lymph flow. The only curative therapy is surgical decortication of the heart.

A 42-year-old woman with multiple hepatic cysts associated with autosomal polycystic kidney disease was evaluated for abdominal discomfort and new liver test abnormalities following blind aspirations of her liver cysts. Tc-99m mebrofenin hepatobiliary imaging revealed a markedly enlarged liver with multiple photon deficient areas, focal retention of isotope in the left hepatic ductal system, no accumulation of radionuclide in cysts, and an unusual medial gallbladder position. Endoscopic retrograde cholangiography confirmed all of these findings. Abdominal discomfort and liver biochemical abnormalities were attributed to cyst compression of nearby structures, including bile ducts. Hepatobiliary imaging is useful to exclude communication of bile ducts with hepatic cysts, to detect incidental abnormalities such as partial bile duct obstruction, and to distinguish the gallbladder from nearby hepatic cysts.

Ninety-three (40.6%) cases have metastatic tumour deposits in the liver out of all the primary malignant tumours seen at autopsy during the study period (1983-86). An overwhelming preponderance (39.8%) of hepatic metastases was due to tumours of the reticulo-endothelial system. This is notable when compared with the reports in the Caucasians. Many of the patients presented as if they were primary liver tumours with weight loss, hepatomegaly, abdominal discomfort and upper abdominal mass as major clinical features. This study has shown that a cirrhotic liver is particularly immune to invasion by metastases, when compared with the incidence of primary cancer in cirrhotic livers (Z = 9.32; P less than 0.001).

Schistosoma mansoni was introduced in the Richard Toll area (Senegal) around 1988, probably due to man-made ecological changes in the Senegal river basin. Since 1991, we investigate the community of Ndombo, close to Richard Toll. Four random population samples of approximately 400 subjects are surveyed, starting at 8 months intervals. Each cohort is examined parasitologically (Kato-Katz), clinically, serologically (circulating antigen and antibody profiles); treated with praziquantel 40 mg/kg; and followed up 6-12 weeks, 1 and 2 years after treatment. Water contact patterns and snail densities are longitudinally surveyed. In the first cohort, prevalence of infection was 91%, with 41% excreting over 1000 eggs per gram (epg); the mean egg count was 646 epg, individual counts up to 24,000 epg. Prevalences remained almost 100%, but egg counts declined strongly in adults, in spite of continued exposure and the supposed lack of acquired immunity. Antigen detection in serum and urine confirmed that the egg counts genuinely reflect variations of worm burdens. Serum circulating anodic antigen (CAA) provided intriguing epidemiological information on worm burdens, while circulating cathodic antigen (CCA) showed promise for non-invasive diagnosis and screening. So far, similar epidemiological results were found in subsequent cohorts, although some variations were observed, possibly due to seasonal transmission fluctuations. IgE levels increased with age, while IgG4 peaked in the age-group 10-19 years. IgE and IgG4-levels against adult worm antigen (AWA) and soluble egg antigen (SEA) increased between cohort 1 and cohort 3 in almost all age-groups. In all 3 cohorts examined so far a strong correlation between IgG4 and pre-treatment egg-load was observed. Further follow-up and analysis, and comparison with chronically infected populations will provide insight in the development of acquired immunity. Abdominal discomfort was reported by 61% and diarrhoea by 33% of the subjects in the first cohort; mild hepatomegaly was found in 16%, splenomegaly in 0.5%. There was no correlation between frequency of symptoms and egg counts. This low morbidity, in spite of intense infections, was confirmed by ultrasound, and may be due to the recent nature of the focus. In the first cohort, 82% of treated subjects still excreted eggs 12 weeks after treatment, though egg counts declined strongly. Antigen detection confirmed these results. Parasitological negativation rates in subsequent cohorts, followed up sooner after treatment, improved but remained remarkably low. The low drug efficacy may be due to very rapid reinfection (though further reinfection after one year was limited), and/or to the lack of immunity in the population. Reduced susceptibility of the local schistosome strain can not be excluded, however. Praziquantel treatment provoked impressive but transient side effects (colics, vomiting, urticaria, oedema), the frequency of which correlated with intensity of infection.

A study of morbidity due to Schistosoma mansoni infection was carried out in Ndombo, a recently established but intense focus in northern Senegal. A random population sample (n = 422) was examined by repeated egg counts, standardized interviews, and clinical examinations. Egg counts were positive in 91%, with more than 1,000 eggs per gram of feces in 41% of the subjects. Abdominal discomfort was reported by 60% of the subjects, diarrhea by 33%; 17% of the stools were liquid upon inspection. Hepatomegaly was mostly mild and found in 7% of the subjects, mainly in males less than 20 years of age. Splenomegaly was detected in only 0.5% of the people examined. There was no significant correlation between the frequency of complaints or symptoms and egg counts. The remarkably mild morbidity in spite of the intense level of many infections may be explained by the recent nature of the focus; more severe chronic morbidity may develop in the future.

Following the introduction of large-scale irrigation, an exceptional epidemic of intestinal schistosomiasis occurred in northern Senegal when a non-immune population was exposed to massive infection. Subjects infected with Schistosoma mansoni were followed up parasitologically and clinically from the onset of the epidemic. After the initial evaluation, patients received a health education session and were treated with praziquantel in a dose of 30 mg/kg. One year after this treatment, S. mansoni eggs were found in the stools of 227/301 subjects (75%). Twenty-three per cent of subjects excreted > 400 eggs per gram (e.p.g.) and 11% excreted > 1000 e.p.g. of faeces. Overall, the geometric mean was 191 e.p.g. of faeces in infected individuals. The prevalence of diarrhoea was reduced from 55 to 29%, the prevalence of bloody diarrhoea from 44 to 11% and the prevalence of abdominal discomfort from 66 to 41%. No hepatomegaly was found in these patients either before or one year after treatment. Splenomegaly was reduced from 30% (measured by ultrasound) to 3% (on clinical examination). Morbidity associated with S. mansoni infection was considerably reduced one year after treatment with praziquantel (30 mg/kg).

AIDS is frequently expressed through gastrointestinal o abdominal symptoms. In addition, patients with AIDS or ARC frequently have hepatic and biliary symptoms, while pancreatic alterations are found in 4-30% of patients hospitalised for AIDS. Since AIDS patients are immunodepressed, they are subject to opportunistic infection often multifocal and the pathological processes can be present simultaneously. About 2/3 of patients have enlarged liver, steatosis, splenomegaly, lymphoadenopathy, cholecystic and biliary tract abnormalities, alterations of liver function tests, and abdominal discomfort in the upper right quadrant. Jaundice is rare and hepatic failure is not common. Hepatic biopsy is often necessary to establish the diagnosis. The hepatic localisation of an opportunistic pathogenic agent is generally a sign of systemic dissemination which is expressed as granulomatous hepatitis (atypical mycobacteria, frequently mycobacterium avium, or M. tuberculosis representing the reactivation of latent diseases), peliosis hepatis, infection from CMV, HSV, EBV, Pneumocystis carinii, and mycotic infections. Coinfections with the hepatic virus (HBV, HDV, HCV) are also often present. Pharmacological damage may also be present (mainly caused by antibiotic therapies). Neoplasia are rare (hepatic Kaposi's sarcoma associated with cutaneous and gastrointestinal manifestations, or generally metastatic lymphoma). Damage of the biliary tract usually develops after other manifestations of the illness; the most frequent pictures are cholestatic syndromes and cholangitis, while cholecystitis and jaundice are rare. Pancreatic lesions are generally asymptomatic. They are diagnosed during autopsy and are caused principally by opportunistic agents.
