Epstein-Barr virus (EBV) infection is ubiquitous and may result in multiple and widely different clinical features; the most common of these is infectious mononucleosis (IM). Recently, a group of patients has been included in the chronic EBV infection syndrome (EBVIS), with a sustained nonspecific syndrome consisting of asthenia, anorexia, low grade fever and changes in mood, associated with a viral infection not necessarily caused by EBV; this has been called chronic fatigue syndrome (CFS). We report a patient who fulfilled the criteria for CFS associated with EBV after an acute, well documented EBV infection. We discuss its etiological and pathophysiological implications, emphasizing the need for extreme caution in the diagnosis of CFS. A merely clinical diagnosis may hide severe mistakes.

In previous work (Leshem, M., Boggan, B., and Epstein, A.N. (1988). The ontogeny of drinking evoked by activation of brain angiotensin in the rat pup. Dev. Psychobiol. Vol.21, pp. 63-75) we showed that thirst elicited by activation of the brain's renin-angiotensin system in the suckling becomes specific to water after 16 days of age. However, in the suckling, we did not find the anorexia that reportedly accompanies angiotensin-induced thirst in the adult. This suggests the existence of a further stage in the ontogeny of thirst. Therefore, the present study pursued the ontogeny of thirst and its effects on milk intake through prepubescence into adulthood. Experiment 1 revealed that intracranial renin does not cause an anorexia to milk in prepubescent or adult rats. Experiment 2 showed that the absence of anorexia is true of thirst induced by renin but not by cellular dehydration, although both dipsogens suppressed milk intake when rats also had water available. Experiment 3 confirmed that the preweanling shows anorexia to solid food, as does the adult. Together with other work, these findings suggest that the ontogeny of the thirsts aroused by renin or intracellular dehydration is complete before weaning.

Twenty five cases of Burkitt's lymphoma in Thai children were diagnosed at the Department of Pediatrics, Siriraj Hospital during the period of 13 years (January 1969 to April 1982). Males were more affected than females with the ratio of 1.7:1. The age ranged from 2 to 11 years with the median age of 4-5 years. The most common clinical manifestations were abdominal mass associated with nausea vomiting, abdominal pain, anorexia, weight loss and generalized lymphadenopathy which occurred in 50-60% of cases. Additional symptoms and signs included anemia, hepatosplenomegaly, edema and pleural effusion. Jaw tumor was found in only 37.5% of the patients. Definite diagnosis depended on the characteristic starry sky appearance of the lymph node biopsy or section of abdominal mass. In advance cases, the tumor cells could be discovered in bone marrow aspiration, ascitic fluid pleural fluid and cerebrospinal fluid. The typical blast cells were detected in the peripheral blood in 4 cases. Antibody to Epstein-Barr virus could be detected in almost all cases with high titers in some cases. Most patients responded very well to local irradiation and chemotherapy with prednisolone plus cyclophosphamide and vincristine or methotrexate. However, relapse occurred rapidly and 80% of the patients died within 3 months after diagnosis with the median survival of only 1 month. Five cases expired early before any specific treatment. The main causes of death were disease, sepsis, excessive bleeding and hyperkalemia.(ABSTRACT TRUNCATED AT 250 WORDS)

We report Hodgkin's disease arising in a 68-year-old patient with a history of chronic lymphocytic leukemia for 8 years. The patient presented with a 4-month history of weakness, loss of appetite, and a 15-pound weight loss. A bone marrow biopsy showed two distinct histologic types of lymphoma: chronic lymphocytic leukemia and Hodgkin's disease. Immunohistochemical studies showed that chronic lymphocytic leukemia cells were composed of kappa-light chain-restricted monoclonal B cells. The Reed-Sternberg cells expressed CD15. Epstein-Barr virus RNA was not identified in either the Reed-Sternberg cells or cells of chronic lymphocytic leukemia by in situ hybridization. To our knowledge, this is the second reported case of composite Hodgkin's disease and chronic lymphocytic leukemia involving the bone marrow.

A benign, transient proliferation of atypical lymphocytes and a monoclonal rearrangement of the T-cell receptor beta (TRB) locus was found in a 60-year-old woman who presented with low-grade fever, anorexia and fatigue. A marked and transient atypical lymphocytosis (white blood cell count 90.5 x 10(9)/l) with CD8 surface antigen improved without specific treatment. Although tests for IgM antibodies to hepatitis A, varicella zoster, Epstein-Barr virus (EBV), and cytomegalovirus (CMV) were all negative, a monoclonal gene rearrangement of TRB locus was observed in the DNA of the proliferated atypical lymphocytes by Southern blotting. The clonal rearrangement and the atypical lymphocytes disappeared after 14 d, and the patient has remained well for 7 years. These results suggest that monoclonal proliferation of CD8 lymphocytes can occur based on a non-neoplastic aetiology.

Acyclovir is an antiviral agent that causes termination of viral DNA synthesis by inhibiting viral reverse transcriptase. Acyclovir is used therapeutically to treat herpes simplex, cytomegalovirus, Epstein-Barr, and varicella-Zoster. Although acyclovir is thought to be low in toxicity, it has caused an obstructive nephropathy from accumulation of crystals in renal tissue. A retrospective review (January 1995 through March 2000) was conducted of acyclovir toxicoses in dogs reported to the ASPCA National Animal Poison Control Center. Of 105 ingestions, 10 were considered cases of acyclovir toxicosis. The most common signs seen were vomiting, diarrhea, anorexia, and lethargy. Ingested dosages ranged from 40 to 2195 mg/kg bw. Polyuria and polydipsia were reported in I dog. In 6/10 cases, signs developed within 3 h of ingestion. Treatment included standard decontamination procedures, (ie induction of emesis, administration of activated charcoal), diuresis, and supportive care.

Looking at the field as a whole through metaanalysis, Shadish et al concluded (based on 162 studies) that marital and family therapies were significantly more effective than no treatment and at least as effective as other forms of psychotherapy. Although these reviews and others are positive, individual studies raise many questions. For instance, based on research findings, family treatments increasingly have become standard care for patients with schizophrenia. It remains unclear what degree and type of family involvement is needed for which patients at which stage of their disorder. In the area of anxiety and depression, there are too few studies to make any strong conclusion. Although investigators such as Barrett, Cobham, and Diamond have produced some positive results, the Lewinsohn and Clark studies fail to demonstrate the added benefit of family involvement. Although Brent's study showed CBT to reduce depression faster, family therapy and supportive therapy did just as well in the long run, and family conflict was a strong risk factor for relapse. In the area of anorexia, Russell and Robins produced strong results from family interventions, whereas Geist found no difference between different types of family interventions. Family treatments for obesity have been inconsistent. In a metaanalysis of 41 studies, parental involvement did not contribute significantly to outcomes. In the Epstein study, however, which included 5- and 10-year follow-up, the results of family intervention were impressive. Although many of these studies can be cited for various methodologic flaws, the most consistent problem is that sample sizes are too small to detect difference between two or more active treatments. The most consistent findings (and most well-done, large studies) that support the efficacy of family-based interventions are done with externalizing problems. Work groups led by Patterson, Eisenstadt, Webster-Stratton, Alexander, and Henggeler all have produced impressive reductions of oppositional and antisocial behavior. Clinical programs that treat these populations without using a family-based intervention as at least a component of a treatment package are seriously ignoring the findings of contemporary intervention science. Programs of research by Henggeler, Szapocznik, and Liddle demonstrate similarly impressive results for substance abusing adolescents. Although preliminary results from the Dennis et al study suggest that various treatment approaches may benefit this population. Family interventions have had less success in reducing ADHD symptoms, yet these psychosocial treatments have been essential in reducing much of the family and school behavior problems associated with this disorder. Many investigators would agree that a combined medication and family treatment approach may be the treatment of choice for children with ADHD. In fact, many studies across various disorders suggest that patients respond best to comprehensive treatment packages, of which a family treatment is at least one component. Although the data are promising, many challenges lie ahead. Although collectively many family intervention studies exist, many disorders lack enough rigorous and large-scale investigations to make any strong conclusions. Kazdin argues that sample sizes of 150 are essential to detect significant differences between active treatments, and few of the reviewed studies include these kinds of patient numbers. Furthermore, not enough committed and sophisticated family treatment researchers have carried out some of the major studies. For example, the Brent study on depression and the Barkley study of ADHD, although testing family approaches, lacked well-developed and published treatment manuals, a demonstration of the necessary expertise to supervise these treatments, and data about training and adherence to these models. Although the absence of expertise limits investigator allegiance biases, treatment development and modification are essential for tailoring family treatments to target family processes specific to each disorder. Investigators such as Patterson and Liddle have invested great effort in rigorously dismantling the treatment process, identifying and refining essential ingredients, and repackaging more potent treatment protocols. This process has paid off well. Programmatic treatment development is needed for many disorders to address myriad questions. What are the essential disorder-specific family processes that should be targeted by interventions? Hostility, criticism, communication, attachment and autonomy, attributional sets, and behavior management are important processes of family life, but each may have more relative importance for specific disorders. With a greater understanding of these processes, treatments could be tailored to target these mechanisms more efficiently and effectively. (ABSTRACT TRUNCATED)

Castleman's disease is a rare B-cell lymphoproliferative disorder of unknown etiology. In this report we describe a 54-year-old woman with a 10-year history of asymptomatic bilateral, multiple cervical lymph node enlargements. She was not evaluated by lymph node biopsy during this period. She had been well until four months previously. The patient presented with multiple enlarged lymph nodes and systemic symptoms including fever, sweats, weight loss, and anorexia. Two lymph nodes were biopsied, yielding a diagnosis of multicentric Castleman's disease (MCCD) of mixed hyaline-vascular and plasma cell type histology. Serologic studies revealed the simultaneous presence of an acute Epstein-Barr virus (EBV) infection. She experienced an aggressive clinical course with a fatal outcome.

An 82-year-old woman was admitted with fever and anorexia. Aggravated pancytopenia and liver dysfunction suggested the presence of disseminated intravascular coagulation. The serum ferritin level increased to 9,100 ng/ml. Bone marrow aspiration showed an increase of histiocytes with phagocytosis and a diagnosis of hemophagocytic syndrome was made. Symptomatic therapy was performed because of her deteriorated general condition. She died of multiple organ failure, 32 days after admission. Autopsy revealed swollen lymph nodes with proliferation of large neoplastic cells containing rich cytoplasm and pleomorphic and multi-segmented large nuclei. The immunophenotype of the neoplastic cells was LCA-, CD3-, CD5-, CD 20-, CD79a-, UCHL1-, MT1-, CD15-, p80-. Neoplastic cells were positive for CD30, mainly in Golgi apparati, and also positive for EBV-encoded small nonpolyadenylated RNAs (EBER). This case was diagnosed as anaplastic large cell lymphoma (ALCL) associated with hemophagocytic syndrome. It was estimated that Epstein-Barr virus had played an important role in the development of ALCL in the present case.
