Detection and molecular typing of Borrelia burgdorferi sensu lato in Ixodes ricinus ticks and in different patient samples from southwest Germany.

The prevalence of different genospecies of Borrelia burgdorferi sensu lato in infected ticks could be a determinant for the risk of acquiring Lyme borreliosis (LB) and its clinical presentation. A total of 7373 ticks and 2761 samples from LB patients from the same area in southwest Germany were analyzed by PCR to assess the frequency of the occurrence of LB-associated genospecies. Fifteen percent of the tick samples and 19% of the human samples were found positive for the presence of B.

DNA fragments in the blood plasma of cancer patients: quantitations and evidence for their origin from apoptotic and necrotic cells.

Increased levels of DNA fragments have frequently been found in the blood plasma of cancer patients. Published data suggest that only a fraction of the DNA in blood plasma is derived from cancer cells. However, it is not known how much of the circulating DNA is from cancer or from noncancer cells.

[Autonomy of the thyroid gland: is there an "organ hyperthyroidism" of "euthyroid" patients?].

Background: Classic thyrotoxicosis is defined as the clinical syndrome of hypermetabolism that results when concentrations of serum free thyroxine (fT4), serum free triiodothyronine (fT3), or both are increased and serum level of TSH is suppressed. The term of subclinical thyrotoxicosis refers to a usually asymptomatic state associated with normal serum fT4 and fT3 and low serum TSH concentrations.

Aim: We describe a new entity of thyrotoxicosis under the term of "organ-selective thyrotoxicosis".
