In quantification of pleural effusions, the sonographic measurement method presented is preferable to radiographic measurement.

We propose a role for Th17 and Th2 T cells in chronic inflammation in lungs of patients with CF. High concentrations of these cytokines/chemokines in CF airways precede infection with P. aeruginosa.

Melanomas contain distinct cell subpopulations. Several of these subpopulations, including one expressing CD20, may harbor stem cell-like or tumor-initiating characteristics. We hypothesized that patients at high risk of disease recurrence could benefit from an adjuvant anti-CD20 therapy. Therefore, we initiated a small pilot trial to study the effect of the anti-CD20 antibody rituximab in a group of melanoma patients with stage IV metastatic disease who had been rendered without evident disease by way of surgery, chemotherapy and/or radiation therapy. The major objective was safety, while secondary objectives were description of recurrence-free intervals (RFI) and overall survival (OS). Nine patients received rituximab at 375 mg/m(2) qw for 4 weeks followed by a maintenance therapy every 8 weeks. Treatment was discontinued after 2 years or with disease recurrence. Treatment was well tolerated. After a median observation of 42 months, the median neither of RFI nor of OS has been reached. Despite therapy that ended after 2 years, six out of nine patients are still alive and five of them are recurrence-free. Though the patient number is too small for definitive conclusions, our data may represent a first example of the potential therapeutic value of targeting CD20(+) cell populations-at least for a subset of patients.

CLM are diagnosed antenatally with an increasing frequency and are shown to be quite different from previously applied concepts. The expected clinical outcome is far better than thought to be possible.

In humans, cystic echinococcosis is one of the most serious helminthic diseases worldwide. The larval stages (cysts) of Echinococcus granulosus are mainly located in the liver and the lung. Other locations of infection are rare, which may occasionally hinder its diagnosis. A 14-year-old girl from Kosovo presented with a cystic lesion in the left thyroid lobe of 4 years duration. Although two percutaneous punctures had been performed, she developed a recurrence and therefore had to undergo thyroid surgery. The results of the histopathologic examination revealed a hydatid cyst, and consequently, the patient received a long-term course of medication, namely, albendazole. Imaging of the cranium and chest were normal. A computed tomography of the abdomen detected a further cyst in the liver which did not show the typical signs of cystic echinococcosis. An echinococcus cyst in the thyroid gland is rare, especially in children. In a review of the literature published since 1965, only 12 children have been reported. Although by definition percutaneous drainage is contraindicated to avoid the spread of protoscolices, it is documented in eleven patients without complications. Surgical extirpation is mandatory. Chemotherapy with benzomidazole derivatives is necessary to avoid recurrence.
