[Anaplastic large cell lymphoma. Report of an unusual case].

An anaplastic large cell lymphoma which fulfills all the criteria required for its inclusion among the soft tissue forms is reported. We point out in this case, in addition to its low frequency in adults, the severe systemic involvement of the disorder with out generalization, the lack of expression of the ALK1 protein, frequently positive in the generalized forms and the absence of response to polichiomiotherapy. We think that this case emphasizes the heterogenicity if the disorder on the clinical pathologycal relation ship of this kind of lymphomas.

[Incidence of primary gastric lymphoma and H. pylori infection in the central zone of Asturias].

OBJECTIVE: We review our experience with primary gastric lymphomas type B of low (MALT) and high grade in a population of 366,635 people during 4 years and after performing 9,268 gastroscopies. RESULTS: The incidence of these lymphomas in our medium is similar to that found in the world population. Possible disagreements among the biopsy histology and that of the subsequent gastrectomy samples is pointed out. CONCLUSIONS: The frequency of H. pylori involvement in our primary gastric lymphomas is similar to that reported in the literature for the age of our patients, for the MALT lymphomas an well as for the type B high grade.

[Castleman's disease: a histological concept for a wide clinical spectrum].

A literature review about Castleman's disease after a clinical case with different manifestations of this entity was done. Special emphasis on the histological and clinical aspects of the sickness was given. The different pathological patterns and their broader spread do not match necessarily with the different clinical presentations described. Further conclusions regarding their evolution, prognosis and treatment response can not be easily obtained from these data.

[A case of uterine leiomyoma with pulmonary metastasis].

In a 34-years-old patient complaining about persistent dry cough, multiple bilateral pulmonary nodules were observed. The extremely good condition of the patient and the history of resection four years before of an uterine myoma suggested a pulmonary leiomyomatosis. The hystological study after a pulmonary segmentomy confirmed this diagnostic suspicion. The presence of benign pulmonary metastasis in an uterine leiomyoma is a very rare complication. We review the literature therapeutic aspects of this interesting entity.

[Mixed type-II cryoglobulinemia associated with a chronic hepatitis C virus infection].

We describe the case of a patient with non A-non B post-transfusional cirrhosis and type-II mixed cryoglobulinemia, who showed in relation with said processes several acute symptoms of vasculitis, polyarthritis, pericarditis and autoimmune hemolytic anemia, finally dying due to an advanced hepatocellular insufficiency. In this patient the determination of antibodies against hepatitis C virus (anti-HCV) was positive, that is why we assume a possible relationship between both processes and the first literature references, after the clonation of the hepatitis C virus (HCV) genome, are reviewed.

[Acute-phase reactants in sepsis].

In 71 patients with fever and bacteremia without complications, a prospective study of acute-phase reactants is done. Raises in haptoglobin, ceruloplasmin, alpha-1-antitrypsin, protein C, beta-2-microglobulin, IgA and ferritin serum levels, together with leucocytosis and GSR, were very significant when diagnosis was done. Fibronectin, sideremia and transferrin were lowered. After 3 and 6 days of treatment haptoglobins, alpha-1-antitrypsin, protein C, ferritin, leucocytosis and GSR are lowered, while immunoglobulins, sideremia, transferrin and fibronectin raised, the latter until normalization. Fibronectin as well as changes in iron metabolism were very reliable parameters of inflammation and favorable evolution.

[Epidemiological study of prisoners at risk for AIDS in a Spanish prison].

Different proportions of the several AIDS risk practices in a Spanish prison during 1988 were studied. Also a epidemiologic study of the infectious diseases of the prisoners with some risk of this type was carried out. Of 135 prisoners with risk of AIDS, it was found that 91.2% of them were drug addicts. The index of positive HIV in all the population study was of 65.2%. 81.5% of the sample had at least one B hepatitis marker and 11.1% had HBs-Ag. 15.4% of the last group also showed HBe-Ag positive. Histories of non-A, non-B hepatitis were not evaluated in 9.6% of all the patients studied. 53.3% had sexually transmitted diseases. It is important to mention the high index of active tuberculosis found (12.6% of the sample), which is higher than the maximum values found in various similar papers. We did not find any differences in the grade of affectation between HIV+ and HIV-.
