[Characteristics of patients suffering from chronic pain with depressive symptoms in three different treatment settings]

Only few studies considered demographic and medical characteristics of pain patients with depressive symptoms.

Binding sites of muscarinic and adrenergic receptors in gastrointestinal tissues of dairy cows suffering from left displacement of the abomasum

Muscarinic acetylcholine (M) and adrenergic (AR) receptors mediate gastrointestinal motility. Using radioligand binding assays and real-time polymerase chain reaction, the densities of binding sites and mRNA levels of M(2), M(3), alpha(2AD)- and beta(2)-AR were compared in muscle tissues from the abomasal fundus, pylorus, duodenum, caecum, and external loop of the spiral colon of eight cows with left displacement of abomasum (LDA), and of eight healthy cows. Specific binding of the [(3)H]-ligands to each of the four receptors was competitive and saturable. Binding sites of M(2) (all intestinal sites), M(3) (duodenum and caecum), and of alpha(2AD)-AR (abomasal fundus) were lower (P<0.05) in cows with LDA than in healthy cows. The coefficients of correlation between binding sites and mRNA transcripts of receptors were dissimilar in cows with LDA and healthy cows. The decrease in densities of M (intestine) and of alpha(2AD)-AR (abomasum) receptors suggests their implication in the impairment of motility associated with or leading to LDA.

Levocetirizine is an effective treatment in patients suffering from chronic idiopathic urticaria: a randomized, double-blind, placebo-controlled, parallel, multicenter study

BACKGROUND: Chronic idiopathic urticaria (CIU) is defined by the almost daily presence of urticaria for at least 6 weeks without an identifiable cause. Symptoms include short-lived wheals, itching, and erythema. CIU impedes significantly a patient's quality of life (QoL). Levocetirizine is an antihistamine from the latest generation approved for CIU. AIM: To investigate the efficacy of levocetirizine, 5 mg, and placebo for the symptoms and signs of CIU, as well as for the QoL and productivity. METHODS: The primary criteria of evaluation were the pruritus severity scores over 1 week of treatment and over 4 weeks. The QoL was assessed via the Dermatology Life Quality Index (DLQI). RESULTS: Baseline pruritus severity scores were comparable in the two treatment groups (2.06+/-0.58). After 1 week, levocetirizine was superior to placebo and demonstrated a considerable efficacy (difference=0.78, P<0.001). This efficacy was maintained over the entire study period (4 weeks, P<0.001). The number and size of wheals were considerably reduced compared with placebo over 1 week and over the total treatment period (P

Pathological baroreceptor sensitivity in patients suffering from somatization disorders: do they correlate with symptoms?

We conducted a study to investigate whether patients with somatization disorders (ICD-10, F45.0) show abnormal values in autonomic testing.

PET-CT-guided interventions in the management of FDG-positive lesions in patients suffering from solid malignancies: initial experiences

Positron emission tomography-computed tomography (PET-CT) has gained widespread acceptance as a staging investigation in the diagnostic workup of malignant tumours and may be used to visualize metabolic changes before the evolution of morphological changes. To make histology of PET findings without distinctive structural changes available for treatment decisions, we developed a protocol for multimodal image-guided interventions using an integrated PET-CT machine. We report our first experience in 12 patients admitted for staging and restaging of breast cancer, non-small cell lung cancer, cervical cancer, soft tissue sarcoma, and osteosarcoma. Patients were repositioned according to the findings in PET-CT and intervention was planned based on a subsequent single-bed PET-CT acquisition of the region concerned. The needle was introduced under CT guidance in a step-by-step technique and correct needle position in the centre of the FDG avid lesion was assured by repetition of a single-bed PET-CT acquisition before sampling. The metabolically active part of lesions was accurately targeted in all patients and representative samples were obtained in 92%. No major adverse effects occurred. We conclude that PET-CT guidance for interventions is feasible and may be promising to optimize the diagnostic yield of CT-guided interventions and to make metabolically active lesions without morphological correlate accessible to percutaneous interventions.
