Involvement of the liver by multiple myeloma as nodular lesions: a case diagnosed by fine-needle aspiration and immunocytochemistry.

Liver involvement by multiple myeloma as space-occupying lesions is a rare condition with only a few cases reported in the literature. We present a case of a 68-year-old man with a prostatic adenocarcinoma who developed a multiple myeloma as a second primary malignancy. Hepatic nodules were discovered in the tomographic study. Fine-needle aspiration of one of the hepatic lesions showed a pleomorphic plasmacytoid tumor. Immunocytochemistry using p63 and kappa-chain antibodies was useful in determining the plasmacytic nature of the cells.

Enhancement of resistance in mice treated with Lactobacillus casei: effect on Trichinella spiralis infection.

The ability of viable Lactobacillus casei, administered by an intraperitoneal route, to induce resistance in mice against Trichinella spiralis infection was tested. The percent reduction of adult worms in the intestine 5 days after T. spiralis infection observed in L. casei-treated animals, compared with those of the control group, fluctuated between 70.9 and 88.5%; reductions of larvae per gram of muscle tissue, evaluated at 30 days after infection, varied from 46.6 to 84.4% in L. casei-treated mice compared with controls. At 5 days after infection, intestinal villus height was shorter in T. spiralis-infected animals than in L. casei-treated or uninfected mice. There were fewer mast cells/crypt unit in L. casei-treated and uninfected mice than in T. spiralis-infected animals. Lactobacilli-treated mice showed twice as many mononuclear cells/crypt unit as T. spiralis-infected animals. The IFN-gamma serum level was higher in L. casei-treated animals at the time of worm challenge as compared with T. spiralis-infected or uninfected mice. The results indicate that: (1) L. casei increased resistance that acted against T. spiralis infection in mice, (2) this resistance apparently was directed against adult worms in the intestine.

Transverse divergent dislocation of the elbow in a child. A case report.

The transverse divergent dislocation of the elbow in the child is a rare occurrence. In a ten-year-old boy, divergent dislocation was associated with a fracture of the coronoid process and of the radial epiphysis. After a closed reduction and plaster immobilization, full function of the elbow was recovered within nine months.

Chronic granulomatous disease of childhood. Report of two cases with unusual involvement of the gastric antrum and spleen.

Chronic granulomatous disease (CGD) of childhood is a rare entity. The disease is characterized by recurrent infections with granuloma and abscess formation caused by an inherited defective neutrophil leukocyte function. The most common sites of involvement are the lungs, lymph nodes, skin, liver, spleen and bones. Rarely are other organs affected. Two children with CGD are presented. The children were cousins, the older with bone, lung and splenic involvement. The younger had circumferential thickening of the gastric antrum. Some of the lesions were well delineated with ultrasonography. The unusual gastric antrum wall and focal splenic involvement in this disease are emphasized.

[Subcapsular hematoma after ESWL].

Contribution of 2 cases of post-ESWL subcapsular haematoma in patients with HBP. One of them underwent surgical drainage. In the second case a more conservative attitude was followed. Review of related literature.
