Case Reports
Uncommon double fistula between sinus node arteries and right atrium in a patient with atypical chest pain.
The main coronary artery variants and anomalies are completely asymptomatic and are discovered incidentally or as they rise symptoms. Multidetector computed tomography coronary angiography represents an excellent technique for noninvasive assessment of the coronary tree mainly because of the multiplanar imaging modalities of computed tomography. Thin collimation permits to depict thin vessels such as the sinus node artery, as reported in this case. In this brief report, we describe a case of a rare anomaly of termination the coronaries, a double fistula between the sinus node artery, and the right atrium in a patient with atypical chest pain.

The aim of this study was to investigate changes in Nogo receptor 1 (NgR(1)) expression in the cerebrum after cardiopulmonary resuscitation (CPR) in rats. Cardiac arrest was induced by alternating current in 50 SD rats through transcutaneous electrical epicardium stimulation, and CPR was performed with the Utstein mode 6 minutes after cardiac arrest. Rats were killed 1, 3, and 7 days after CPR. ⋯ Furthermore, there were significant differences between the hippocampus and cerebral cortical cortex at 1 day and 3 days after the CPR (P < .05, respectively). There was a transient increase in NgR(1) in the vulnerable areas of the rat brain after CPR. Blockade of NgR(1) may be important in maintaining the high regenerative capacity of neurons during the time window when NgR(1) expression increases.

Leptospirosis is a common zoonotic infection worldwide and is recognized as an emerging public health problem. Although commonly thought of as a tropical disease, incidence in temperate climates is increasing, with recent outbreaks in the United States and Germany, among other countries. The disease presents with symptoms ranging from fever, headache, nausea, and vomiting to life-threatening multiorgan failure characterized by acute liver failure, nephritis, pulmonary hemorrhage, meningitis, and cardiac arrhythmia. ⋯ Given the nonspecificity of patient symptoms, early diagnosis of leptospirosis can be challenging. Diagnostic uncertainty may lead to delay in recommended intravenous antibiotic treatment. We present a case of severe leptospirosis treated exclusively with supportive measures and intravenous corticosteroids.
