[Inflammatory pseudotumor of the spleen. Review and a new case report].

Splenic inflammatory pseudotumour has been defined as a benign tumour reactive lesion with unspecified reparative or inflammatory alterations. It is a mimicking tumour often confused with other pathologies, primarily, lymphoproliferative disorders. Though its aetiology remains unknown, these tumours are often associated to infectious agents such as the Epstein-Barr virus. We describe a case of a 29 year-old patient with a history of infectious mononucleosis, followed by fever, weight loss, and splenomegaly. Splenectomy detected a homogeneous, whitish 2 cm node diagnosed as splenic inflammatory pseudotumour. The clinical features and diagnosis of this disorder are discussed in relation to the histopathological findings.

[Complications and yield of percutaneous liver biopsy with ultrasonographic marking].

OBJECTIVES: To describe the complications and the diagnostic yield of percutaneous liver biopsies performed under ultrasonographic control in an Internal Medicine department. PATIENTS AND METHODS: A total of 750 percutaneous liver biopsies were performed at the Internal Medicine department of our institution during the 1995-2001 time period. The Menghini technique was employed previous ultrasonographic marking of the puncture site was performed by the same physicians who performed the biopsy. Major and minor complications as well as the diagnostic yield (obtention of diagnostic hepatic tissue) of the technique were recorded. RESULTS: No deaths occurred in our series. Two patients (0.3%) had major complications presenting as liver subcapsular hematoma with hemoperitoneum which resolved with conservative measures. One of them was a male patient with acute leukemia and the other was a woman on antiaggregant therapy. Eight patients (1.1%) had minor complications (vasovagal syncope), all of them young males. In three cases no adequate material for diagnosis was obtained (technique yield 99.6%). CONCLUSIONS: In our series, percutaneous liver biopsy with ultrasonographic marking is a diagnostic technique associated with a low rate of severe complications and with a high diagnostic yield. The use of ultrasonographic marking by the same physicians performed the biopsy does not involve a longer time or increased cost of the technique, provides more safety in the procedure and has a low morbidity rate. This procedure could be used on a routine basis for all percutaneous liver biopsies.

[Mutations in the HFE gene (C282Y, H63D, S65C) in alcoholic patients with finding of iron overload].

INTRODUCTION: The pathogenesis of iron overload in alcoholic individuals is not fully elucidated. The frequency of mutations in hereditary hemochromatosis (HFE) is high in this population. Heterozygotes show data of iron overload similar to those in alcoholic individuals. OBJECTIVE: To analyze whether iron excess among alcoholic individuals is associated with mutations in C282Y, H63D or S65C in the HFE gene. Patients and methods. Thirty-two active alcoholic individuals (29 males and 3 females, age range 30-67 years) with data of iron overload (increased serum ferritin with or without saturation of increased transferrin) were studied. In all individuals, mutations C282Y, H63D and S65C were investigated. From 16 cases, liver histology was available. Data on iron overload were compared between patients with and without mutations. RESULTS: Twenty-two patients (68.8%) did not show any mutation, one (3.1%) was heterozygous for C282Y, three (9.4%) were homozygous for H63D, four (12.5%) were heterozygous for H63D, and two patients (6.3%) were heterozygous for C282Y/H63D. None of the patients was homozygous for C282Y or presented mutation in S65C. Transferrin saturation, serum ferritin and liver iron index were similar among with and without mutations. Three patients (9.3%) were diagnosed of hemochromatosis. One of them was homozygous for H63D, other patient was heterozygous for the combined C282Y/H63D, and in the remaining patient none of the mutations was found. CONCLUSIONS: In our setting, iron overload among alcoholic individuals seems to be independent of the presence of mutations C282Y, H63D and S65C in the HFE gene.

[Plasmacytoma of the thyroid. A review apropos a case].

Isolated presentation of outer bone marrow plasmatic cell neoplasia are non-frequent (less than 10% of all plasmacytomas). Thyroid gland involvement is rarely described. A case where immunohistochemistry confirmed the monoclonal type of proliferative cell is presented. Clinical, pathological and diagnosis criteria, as well as response to treatment, are reviewed.

Insulin sensitivity and metabolic clearance rate of insulin in familial multiple lipomatosis.

Intolerance to glucose in certain kinds of lipomatosis is well documented. This article describes a euglucaemic hyperinsulinaemic clamp study of alterations in glucose and/or insulin metabolism in four members of a single family with familial multiple lipomatosis. Fifteen normal subjects were studied as controls. The four patients exhibited no alteration in tolerance to orally administered glucose. When a Biostator Glucose-Controlled Insulin Infusion System (GCIIS) was used to clamp glycaemia at 4.44 mmol/L with successive insulin infusion rates of (a) 0.5 (b) 1.0 or (c) 5.0 mU/kg/min, there was no difference between patients and controls as regards the value of M, the rate of glucose infusion, but the concentrations of immunoreactive insulin recorded during the last 40 minutes of each phase of the clamp were greater in patients than in controls (45 +/- 2 vs 27 +/- 2 uU/mL (p less than 0.01), 83 +/- 2 vs 60 +/- 5 uU/mL (p less than 0.05) and 537 +/- 48 vs 377 +/- 25 uU/mL (p less than 0.05) for insulin infusion rates (a), (b) and (c) respectively), and the ratio M/IRI was consequently smaller for patients than controls (1.92 +/- 0.41 vs 3.06 +/- 0.19 (p less than 0.05) for an insulin infusion rate of 5 mU/kg/min). The metabolic clearance rate of insulin was likewise slower in patients than controls (p less than 0.01). It is concluded that the four patients studied (all members of the same family) have sub-normal sensitivity to insulin secondary to a sub-normal metabolic clearance rate for insulin.
