Randomized Controlled Trial Comparative Study
[Efficacy of epidural steroid injections for chronic lumbar pain syndromes without neurological deficits : A randomized, double blind study as part of a multimodal treatment concept].
Chronic lumbar pain syndromes without neurological deficits are generated by a multitude of causes. Functional, morphological and psychosocial factors are discussed. In many cases a diseased intervertebral disc is found on radiological examination but the clinical relevance of these findings is not clear. For this study it was postulated that a diseased disc results in a local inflammatory reaction therefore causing pain and impairing treatability of patients. An epidural injection of steroids can reduce inflammation and therefore improve treatability and ultimately treatment outcome. ⋯ After the epidural injection the decrease in pain and increase in treatability was statistically significant. The mechanism of the improvement is not clear and should be examined further. The epidural injection of a steroid in this subgroup of patients did not lead to a clinical improvement in the outcome.

Echocardiography of Right Ventriculo-Arterial Coupling Combined to Cardiopulmonary Exercise Testing to Predict Outcome in Heart Failure.
Pulmonary hypertension, which is related to right ventricular (RV) failure, indicates a poor prognosis in heart failure (HF). Increased ventilatory response and exercise oscillatory ventilation (EOV) also have a negative impact. We hypothesized that the severity classification of HF and risk prediction could be improved by combining functional capacity with cardiopulmonary exercise testing (CPET) and RV-pulmonary circulation coupling, as evaluated by the tricuspid annular plane systolic excursion (TAPSE)-pulmonary artery systolic pressure (PASP) relationship. ⋯ TAPSE/PASP, combined with exercise ventilation, provides relevant clinical and prognostic insights into HF. A low TAPSE/PASP with EOV identifies patients at a particularly high risk of cardiac events.

Rationale for Prospective Assays of Intrathecal Mixtures Including Morphine, Ropivacaine and Ziconotide: Prevention of Adverse Events and Feasibility in Clinical Practice.
Use of intrathecal admixtures is widespread, but compounding these is sometimes challenging and may result in errors and complications causing super-potency or sub potency adverse events in patients or malfunctions in the pump itself. ⋯ Prospective assays provide benefits in ensuring accuracy of intrathecal mixture compounding and in preventing overdosing or sub dosing, most notably concerning Ziconotide.

In Germany approximately 3000 body organs are transplanted annually. In general, all artificially ventilated patients with diagnosed brain death are potential organ donors. All German hospitals are obliged to report potential organ donors and be actively involved in the organ donation process. ⋯ Brain death is associated with complex pathophysiological changes in cardiopulmonary function as well as fluid, electrolyte and metabolic homeostasis. In the case of diagnosed brain death and with permission for organ donation, a precise organ-protective therapy is initiated, essentially focussing on optimal organ perfusion and oxygenation. The quality of organ protection has a direct influence on the outcome of transplantation.

We present a case of a 70-year-old man with enlarged mediastinal and cervical lymph nodes that provided interesting radiologic and pathologic observations. The 70-year-old black man was found to have enlarged mediastinal lymph nodes. He had symptoms of atypical chest pain and generalized weakness for 2 weeks prior to the diagnosis. ⋯ Pulmonary function tests at the time of presentation showed FEV1, FVC, and FEV1/FVC ratio of 123% predicted, 133% predicted, and 0.7, respectively. Meanwhile, total lung capacity and carbon monoxide diffusing capacity were 103% and 107% predicted, respectively. Two weeks before he presented to our institution, the patient underwent bronchoscopy with transbronchial biopsies of the right lower lobe and endobronchial ultrasound-guided transbronchial needle aspiration of the right hilar lymph nodes.
