Waldenström's macroglobulinemia as a diagnostic challenge: case report.

Waldenström's macroglobulinemia is a distinct clinicopathologic entity defined as a B-cell neoplasm characterized by lymphoplasmacytic infiltrate in the bone marrow, with an associated immunoglobulin (Ig) M paraprotein. Clinical manifestations are due to deposition of IgM in the liver, spleen, and/or lymph nodes, so it presents with anemia, hyperviscosity, lymphadenopathy, hepatomegaly, splenomegaly and neurologic symptoms. The main diagnostic criteria are a typical peak on serum protein electrophoresis and malignant cells in bone marrow biopsy samples. There is no standard therapy for the treatment of symptomatic Waldenstrom's macroglobulinemia and no agents have been specifically approved for this disease, but initial treatment usually starts with the monoclonal anti-CD20 antibody rituximab, either alone or in combination with other agents, rather than chemotherapy alone. This article confirms that, despite the existence of more modern imaging methods, ultrasonography still has a significant diagnostic role.

A first case of endoscopical removal of an eroded adjustable gastric band in Croatia.

Laparoscopic gastric banding (LAGB) is one of the most common surgical procedures in the treatment of morbid obesity since it provides good long-term outcomes in weight loss and decrease of comorbidities associated with obesity. Although the procedure has low morbidity and almost none-existing mortality, certain complications can occur. Erosion of the band into the gastric wall is one of the rare complications in LAGB. The reported incidence varies from 1 to 11%, however the largest study reported an incidence of 1.6%. This is in accordance with the incidence in our Centre for obesity, where only one case of erosion occurred among 112 operative procedures. The aim of this paper is to present a patient with gastric band erosion and it's removal by using the endoscopic techniques as a minimally invasive management method.
