The authors review twelve cases of chronic hepatitis seen at the IMSS hospital in Puebla in a span of three years. They analyze and compare clinical, laboratory and biopsy data with special emphasis on the microscopic evolution of the disease and the response to different therapeutic regimes. Gamma-globulins were elevated in 80% and hepatitis B antigen in 50%. RIA is more sensitive than contra-immune electrophoresis. In six cases the diagnosis was of active chronic hepatitis and two of these developed towards cirrhosis; one became chronic persistent hepatitis and the other three are stationary and well controlled with prednisone. One patient died with a clinical picture of portal-systemic encephalitis. The six cases of persistent chronic hepatitis evolved towards a spontaneous cure.

Postmortem examination of 21 patients showed a vacuolar myelopathy resembling that associated with the acquired immunodeficiency syndrome. Underlying diseases included six cases of leukemia or lymphoma, five of carcinoma, three of systemic lupus erythematosus, two of chronic lung disease, and one each of cadaveric renal transplant, cirrhosis, diabetes, hemophagocytic syndrome, and viral encephalitis. Fourteen patients were on long-term steroid therapy and 10 of these also had immunosuppressive chemotherapy. No patient had the acquired immunodeficiency syndrome, although one received blood transfusions in 1978. Signs and symptoms consistent with myelopathy included paraparesis in seven patients, ataxia in one, and bilateral extensor plantar reflexes in one. Microscopic examination showed vacuolation in spinal cord white matter primarily located in posterior and lateral columns. Lipid-laden macrophages and axonal changes were proportional to the severity of the vacuolation, which was severe in five patients, moderate in 10, and mild in six. Eight patients had coexistent viral diseases elsewhere in the central nervous system, but viral-associated antigens or genomic material was not found in regions of vacuolated spinal cord white matter. Although the etiology of these myelopathies is unknown, their association with immune suppression and coexistent viral infection of the central nervous system suggests that an opportunistic viral infection may be important.

The patient, a 29-year-old female, was hospitalized because of clouding of consciousness, fever and right hemiplegia 4 days after the onset. On first examination she was found having fever in the 37 degree range, positive CRP, hepatomegaly, anemia and hepatic function impairment. Neurological examination revealed somnolence, conjugate deviation to the left and stiff neck. The muscular power measured about 3+ for the upper extremities and 0 for the lower extremities. Babinski sign was present on the right side. The spinal fluid showed an increase in cell counts, especially the neutrophil count. CT scans showed diffuse white-matter hypodensity in the left hemisphere. Soon after admission the patient fell into coma and died 6 days after admission. Autopsies led to a diagnosis of Hurst's encephalitis complicated by hepatoma with liver cirrhosis. It was reported that the immune complex was found in 25.9% of liver cirrhosis patients. From this fact it is suggested that Hurst's encephalitis might be elicited by some immunological mechanism.

Reference intervals for prothrombin time (PT) and activated partial thromboplastin time (APPT) of undiluted and serial dilutions of citrated platelet-poor plasma were determined for 30 healthy dogs. The PT and APTT were similarly determined for 32 dogs with naturally occurring hepatic disease. Hepatic disease was confirmed by histopathologic examination of hepatic biopsy materials and comprised degeneration (13 dogs), inflammation (11 dogs), cirrhosis (4 dogs), and neoplasia (4 dogs). Coagulation test values were compared with serum alanine aminotransferase, alkaline phosphatase, and gamma-glutamyl transpeptidase activities and Bromsulphalein retention for sensitivity in detecting hepatic disease in the dog. Coagulation test results were at variance with reference values in 66% of the 32 dogs with hepatic disease; serum alanine aminotransferase, alkaline phosphatase, and gamma-glutamyl transpeptidase were increased in 59%, 72%, and 75%, respectively and Bromsulphalein retention was increased in 22% of the 32 dogs. Thus, the PT and APTT were sensitive indicators of hepatic disease. However, the PT and APTT lacked specificity for any given hepatic disease. The sensitivity of the coagulation tests for detecting hepatic disease was enhanced by using dilutions of citrated platelet-poor plasma. Only 15% of dogs with hepatic disease showed variances from reference values in the coagulation tests done with undiluted plasma, but 66% showed variances in the tests with dilutions of plasma. Coagulation tests were also done in 13 dogs with normal hepatic function amd morphology, but with various extrahepatic diseases: chronic renal disease (5 dogs), dirofilariasis (4 dogs), encephalitis (1 dog), cutaneous disease (2 dogs), and femoral fracture (1 dog). Twelve of the 13 dogs had coagulation test values within the reference intervals.

We studied 18 formalin-fixed brains using MRI, and correlated our data with subsequent gross and microscopic examinations. 9 of our patients died from brain diseases (stroke due to infarction 4, stroke due to hemorrhage 1, encephalitis 2, head injury 1, brain tumor 1). 9 of our patients died from non-CNS diseases (stomach cancer 1, colon cancer 1, liver cirrhosis 1, myocardial infarction 2, trauma 4). In MRI of postmortem brain, T1WI and T 2WI was able to clearly show the myelination process of brainstem, basal ganglia, internal capsule and optic radiation in a 2 months-old-boy. The findings were similar to MRI of live infants. In normal adult postmortem brains, the T1WI showed a relatively low signal intensity of white matter as compared to gray matter. The pictures were similar to proton density images, not T1WI of normal adult brains. The reason why the signal intensity of the white matter was lower than the gray matter may have been due to lysis of lipid of myelin sheath in the formalin solution. Postmortem MRI was able to detect the periventricular hyperintensity (corresponding to arteriosclerotic encephalopathy) and subcortical hyperintensity spots (which corresponding to the widening of the Virchow-Robin perivascular space because of arteriosclerosis) in the brains of our elderly patients. Postmortem MRI detected the intracerebral hemorrhage, which appeared as a dark signal in both short and long TR images. However, MRI did not show blood in the ventricles, sulci, or superficial hemorrhages in the cortex of brain. Brain edema was revealed in the postmortem MRI and appeared as low signal intensity in T1WI and hyperintensity in T2WI. It was associated with a significant mass effect.(ABSTRACT TRUNCATED AT 250 WORDS)

Protein tyrosine kinases (PTKs) play a key role in normal cell and tissue development. Enhanced PTK activity is intimately correlated with proliferative diseases, such as cancers, leukemias, psoriasis, and restenosis. This realization prompted us to systematically synthesize tyrosine phosphorylation inhibitors (tyrphostins) as potential drugs. Over the years, we have demonstrated the ability to synthesize selective tyrphostins aimed at different receptor, as well as at nonreceptor, tyrosine kinases. Some of these tyrphostins have shown efficacy in vivo as antileukemic agents and antirestenosis agents. AG 490, a Jak-2 inhibitor, is potent against recurrent pre-B acute lymphoblastic leukemia. AG 1295, a selective platelet-derived growth factor receptor kinase inhibitor, inhibits 50% of balloon injury-induced stenosis in the phemoral arteries of pigs. AG 1517 (SU 5271), a potent epiderminal growth factor receptor kinase inhibitor, is currently in clinical trials for psoriasis. Similarly, SU 5416, a potent kinase inhibitor of the vascular endothelial growth factor receptor/kinase domain receptor/Flk-1, is currently in clinical trials as an anticancer agent by virtue of its strong anti-angiogenic activity. These findings demonstrate that the identification of PTKs that play a key role in a defined disease state can lead to a selective drug. Tyrphostins also show efficacy in vivo in inflammatory diseases such as sepsis, cirrhosis, and experimental autoimmune encephalitis.

The family Flaviviridae contains three genera: Hepacivirus, Flavivirus, and Pestivirus. Worldwide, more than 170 million people are chronically infected with Hepatitis C virus and are at risk of developing cirrhosis and/or liver cancer. In addition, infections with arthropod-borne flaviviruses (such as dengue fever, Japanese encephalitis, tick-borne encephalitis, St. Louis encephalitis, Murray Valley encephalitis, West Nile, and yellow fever viruses) are emerging throughout the world. The pestiviruses have a serious impact on livestock. Unfortunately, no specific antiviral therapy is available for the treatment or the prevention of infections with members of the Flaviviridae. Ongoing research has identified possible targets for inhibition, including binding of the virus to the cell, uptake of the virus into the cell, the internal ribosome entry site of hepaciviruses and pestiviruses, the capping mechanism of flaviviruses, the viral proteases, the viral RNA-dependent RNA polymerase, and the viral helicase. In light of recent developments, the prevalence of infections caused by these viruses, the disease spectrum, and the impact of infections, different strategies that could be pursued to specifically inhibit viral targets and animal models that are available to study the pathogenesis and antiviral strategies are reviewed.

We report a patient with cerebellar meningo-encephalitis by Epstein-Barr virus(EBV) in which the responsible lesions were detected by Gd-enhanced MRI. A 61-year-old woman with a history of liver cirrhosis and diabetes mellitus presented with cerebellar signs such as ataxia of the trunk, bilateral upper and lower extremities and slurred speech two weeks after the acute upper respiratory inflammation for several days. Serum IgM antibody(Ab) to EBV viral capsid antigen(VCA) was 1:10, Ab to EBV(VCA) IgG was 1:1280, Ab to early antigen diffuse and restricted (EADR) IgG was 1:40, Ab to EBV nuclear antigen (EBNA) was 1:80. Other viral antibody titers were not elevated significantly in serum. Cerebrospinal fluid (CSF) pressure was 195 mmH2O, containing 464 cells/mm3, protein 68 mg/dl and glucose 43 mg/dl. Only CFS Ab to EBV(VCA) IgG elevated significantly (1:16). In acute phase plain MRI was normal except for swelling of the cerebellar hemispheres while Gd-enhanced MRI showed a leptomeningeal enhancement of bilateral cerebellar hemispheres and of vermis disappeared within one month. A homogeneously enhanced lesion in the left dentate nucleus appeared one month after the onset of illness. This lesion had been detected on Gd-enhanced MRI for three months after clinical symptoms were improved. No abnormal finding was shown in the supratentorial region during the whole clinical course. In the literature, EBV encephalitis has a wide range of MR findings which may vary in a short period. We emphasize that frequent MR examinations including Gd-enhanced MRI is useful to evaluate inflammatory or demyelinating diseases in the posterior fossa.

Two child and three elderly patients underwent craniotomy for organized and/or partially calcified chronic subdural hematomas (CSHs). The characteristic feature of magnetic resonance imaging was a heterogeneous web-like structure in the hematoma cavity. Both children had undergone one side subduroperitoneal shunt for bilateral CSHs when infants. As a result, the opposite hematoma cavities persisted and developed into calcified CSHs after a couple of years. All three elderly patients with senile brain atrophy showed various systemic complications such as cerebral infarction, diabetes mellitus, leg ulceration, cirrhosis, and bleeding tendency. Craniotomy for removal of the hematoma and calcification achieved good results in all patients. Subdural space created by shunt, craniotomy, or brain atrophy and persisting for a certain period, and additional various brain damage such as microcirculatory disorder, meningitis, encephalitis, or premature delivery may be important in generating calcified or organized CSH.

Hepatitis due to Listeria monocytogenes is uncommon in adults. This report describes the first case observed in Senegal. The patient was a 73-year old man presenting listeria-related hepatitis presumably secondary to low-grade meningeal encephalitis. Treatment using ampicillin was unsuccessful and the patient died four days after hospitalization. The authors note that the incidence of adult listeriosis has risen constantly for the past twenty years in relation with alcohol abuse, cirrhosis, diabetes, kidney insufficiency, cancer, AIDS, and organ transplantation. However no predisposing factors were observed in the present case.
