Lifetime diagnoses in patients with somatoform disorders: Which came first?

Thirty inpatients with somatoform disorders were examined with the structured clinical interview SCID for psychiatric lifetime diagnosis. In the present diagnoses, we found a concordance of 63% for somatoform and affective disorders and the lifetime comorbidity of both disorders was 87%. Additionally, patients with somatoform disorders frequently had a history of other psychiatric disorders (for example, anxiety disorders, 40%). For 73% of patients with somatoform disorders and a history of affective disorders, the onset of the somatoform disorder was prior to the onset of another psychiatric disorder. The time interval between the onsets of somatoform disorders and affective disorders was greater than 1 year for most patients; for 46% of the patients with a history of both disorders, the time interval between the two disorders was more than 5 years. The course of illness for somatoform and affective disorders was quite different; while affective disorders tended to episodic periods with interim remissions, the somatoform disorders usually showed long, chronic courses (mean duration of the current somatoform disorder was 11.9 years). Finally, the Symptom Check List SCL-90R demonstrated good discrimination between patients with affective and anxiety disorders. However, the SCL-90R failed to discriminate patients with somatoform disorders from affective- and anxiety-disordered subjects. Therefore, the development of other psychometric scales is necessary for the evaluation of patients with somatoform disorders.     

Evaluation of a new generation of plastic evacuated blood-collection tubes in clinical chemistry, therapeutic drug monitoring, hormone and trace metal analysis.

Polyethylene terephthalate (PET) tubes have several advantages over glass tubes: they are unbreakable, lighter and more easily disposed of. Despite a steady increase in their use and an expansion of the range of available tubes, few studies validating their use have been published in the literature. This paper describes the various studies that have been performed to compare VENOJECT glass, VENOSAFE PET and VENOSAFE PET/heparin tubes for the assay of a panel of analytes in routine clinical chemistry, immunochemistry, hormone and tumor marker analysis and trace metal determination. These studies demonstrate that VENOSAFE PET tubes are a suitable alternative to glass tubes.

Upregulation of CD40, CD80, CD83 or CD86 on alveolar macrophages after lung transplantation.

BACKGROUND: Alveolar macrophages (AMs) are known to be poor antigen-presenting cells, and lack the accessory molecules such as CD40, CD80 or CD86 to activate T cells. The question raised is about the potential changes in phenotypes after lung transplantation, particularly during acute rejection episodes. METHODS: The present study analyzed the phenotype of AMs longitudinally in 45 lung transplant patients, between August 1997 and April 2002, with a follow-up period of 27.2 +/- 2.5 (mean +/- SEM) months. There were 7.7 +/- 0.6 bronchoalveolar lavage (BAL) assessments performed per patient (i.e., 345 BALs), simultaneously with transbronchial biopsies. Transplantation was soon followed by a progressive upregulation of CD40 on 49.7 +/- 8% of AMs during the first month, and this marker remained elevated at 60 +/- 8% after 5 years. RESULTS: Both CD86 and CD80, as well as CD83, a marker of dendritic cells, were enhanced for most AMs during Grade A2 and A3 rejection episodes. A correlation was found between expression of CD83 and CD86, but not between CD1a and CD86. Immunohistology confirmed that CD40-positive cells in the alveoli corresponded to AMs and to some dendritic cells in the basal layers of the airways. In vitro studies showed that harvested AMs with these enhanced accessory molecules remained poor stimulators of allogeneic cells, a phenomenon that may be related to the ongoing immunosuppressive treatments. CONCLUSIONS: AM phenotypes showed marked changes during early or late acute rejection episodes, acquiring CD80, CD83 and CD86, while CD40 expression was further enhanced. This finding may provide clues on how to monitor the tolerance of transplanted lungs and may also provide new insights into the pathophysiology of lung transplantation.     

Hämatologische Störungen bei Intensivpatienten

This final issue of the series "Emergency and intensive care therapy for hematooncological diseases" reviews cytopenias in intensive care patients who do not offer any oncological or haematological problems in their medical history. Anaemia is a very common problem in the intensive care setting. We highlight aetiological aspects of anaemia in critically ill patients and discuss therapeutical options like substitution of blood and application of erythropoietin, respectively. The second paragraph focuses on leukocytopenia and agranulocytosis, their causation and therapy and among other things the application of G-CSF (Granulocyte colony-stimulating factor). Last but not least, we deal with thrombocytopenia, especially heparin-induced thrombocytopenia.

Case Report: Corroboration of the lower extremity counterpart of the Poland sequence

Gluteal and lower extremity hypoplasia with ipsilateral toe brachysyndactyly were noted in a 23-year-old woman similarly affected to the only previously reported case of the lower extremity counterpart of Poland sequence. Since no neurological deficit was found, and electromyographic and nerve conduction studies in the affected limb were normal, we propose a vascular origin which would involve the external iliac artery supply analogous to the subclavian artery supply disruption in the upper extremity Poland sequence.     

A phase II study of sulofenur,a novel sulfonylurea,in recurrent epithelial ovarian cancer

Summary A total of 16 patients with recurrent epithelial ovarian cancer were treated with sulofenur (LY 186641), a novel oral sulfonylurea. All subjects had received previous chemotherapy. Anaemia occurred in all 16 patients, 14 of whom required a blood transfusion, and 2/16 patients received methylene blue for breathlessness due to methaemaglobinaemia. Treatment was discontinued in 2/16 cases due to rising liver enzyme values, which reverted to normal on cessation of the drug. There was no nausea or alopecia. Only two minor responses were seen. Plasma drug levels were insufficient to result in antitumour activity as extrapolated from animal data. Further studies that attempt to increase the bioavailability and improve the therapeutic index are warranted.
