[Myocardial infarction and coronary artery ventricular fistulas due to blunt chest trauma]
An 18-year-old previously healthy, cigarette smoking man with no other risk factors for ischaemic heart disease, was admitted to hospital after being kicked in the chest by a horse. On arrival he complained about pain in the lower mediastinum. INVESTIGATIONS: The ECG showed sinus rhythm, right bundle branch block and convex bowed ST elevation in leads V1-V3. Sixty minutes after the incident the cardiac enzymes (creatinekinase-MB fraction, troponin I) were significantly raised. Despite an only slightly reduced left ventricular function documented by transthoracic echocardiography, SPECT-thallium scan showed large scintigraphic defects. Coronary heart disease was excluded by coronary angiography. Four small coronary-ventricular fistulas were identified. Laevocardiography showed a hypokinesia in the antero-septal region. DIAGNOSIS, TREATMENT AND COURSE: We assumed traumatic myocardial infarction of the anterior wall and rupture of multiple small coronary vessels, leading to coronary-ventricular fistulas. No interventional or surgical therapy was performed. Later on the left ventricular function became normal. Echocardiography merely outlined an akinetic scar in the middle of the septum. At exercise ECG test sixteen months later, the patient remained asymptomatic and was able to exercise without any signs of ischaemia up to a work load of 175 W. Furthermore, the fistulas could be seen by echocardiography. ⋯ Cardiac involvement should be considered in all cases of blunt chest trauma. In addition to a traumatic myocardial infarction fistulas may also, though rarely, occur. Myocardial scintigraphy after cardiac contusion is not suitable for diagnosing myocardial ischaemia or vitability.

Objective. To identify aspects of daily life that have been most affected by chronic low back pain among spinal cord stimulation (SCS) patients and to determine the relative contribution that improvement in each would make to patients' quality of life (QOL). Materials and Methods. ⋯ Patients with chronic low back pain seek improvement in multiple dimensions of QOL after SCS, particularly increased physical activity, social relations, work status, and mood. It is likely that patients' assessment of SCS "success" correlates highly with functional improvement. As such, an understanding of SCS therapeutic benefit and satisfaction requires that QOL be carefully assessed in future outcome trials.

Effects of ulinastatin (urinary trypsin inhibitor) on ATP, intracellular pH, and intracellular sodium transients during ischemia and reperfusion in the rat kidney in vivo.
To investigate the effects of ulinastatin on renal ischemia-reperfusion injury, we monitored the dynamic changes in ATP, intracellular pH (pHi), and intracellular sodium (Nai) in rats in vivo. ⋯ The transcellular sodium gradient is restored before the ATP level is normalized during postischemic reperfusion. Ulinastatin might protect mitochondrial conformation during ischemia, and facilitate functional recovery of the ionic pump after reperfusion.

Neuromuscular blocking agents (NMBA) are frequently utilized in the ICU, primarily to facilitate mechanical ventilation. An ideal NMBA is nondepolarizing, has no propensity to accumulate, is easily titrated, has a rapid onset and offset, does not rely on organ function for metabolism, and has no toxic or active metabolites. Current NMBAs are classified as aminosteroids or benzylisoquinoliniums and have different features, but none are ideal. ⋯ There are well-recognized complications of NMBA, including prolonged drug effect and acute quadriplegic myopathy. The latter condition can result in prolonged rehabilitation. The use of an NMBA can be essential for the successful outcome from critical illness; however, cautious use of these agents with a structured approach to minimize complications is urged.

Interstitial cystitis is the most disabling nonmalignant disorder seen by urologists. Chronic debilitating urinary bladder symptoms (severe pain and pelvic floor muscular dysfunction) often progress despite maximal medical attempts at management. Although the exact cause remains unknown, a neuropathic etiology has recently been suggested( 1,2). This case report describes the use of Selective Nerve Root Stimulation (SNRS) for the treatment of intractable pelvic pain and motor dysfunction in a patient with Interstitial cystitis (IC).
