ABSTRACT

Hemothorax is a possible immediate complication of central venous catheterization. We experienced a patient who suffered from massive hemothorax 72 hours after right subclavian venous catheterization. A 29-year-old female patient with Marfan's syndrome underwent the Bentall's operation and aortic arch replacement with an artificial graft, which was performed uneventfully. She recovered favorably in the intensive care unit and was transferred to the general ward on postoperative day 3. Immediately after the removal of the catheter in the general ward, massive hemothorax developed and emergent thoracotomy should have been performed to control bleeding. We report this case to re-emphasize the careful monitoring even after removal of central venous catheter and the need for ultrasound guidance during insertion of central venous catheters.

ABSTRACT

Classical trigeminal neuralgia is characterized by recurrent attacks of lancinating pain in the trigeminal nerve distribution, and no cause of the symptoms can be identified, other than vascular compression. This type of injury may rarely be caused by identifiable conditions, including tumor in the cerebellopontine angle. If the patient is suspected for secondary trigeminal neuralgia, further evaluation is required to diagnose and treat correctly. We report a case of a 49-year-old woman with a 1-month history of facial pain, who was initially misdiagnosed as odontalgia, and even treated with the extraction of her molar teeth. This case with the review of secondary trigeminal neuralgia may highlight the difficulties of diagnosis, and the importance of early diagnostic imaging, when trigeminal neuralgia occurs with a brain tumor.

ABSTRACT

BACKGROUND: Reactive oxygen species and inflammatory responses contribute to the development of neuropathic pain. Superoxide serves to mediate cell signaling processes and tissue injury during inflammation. We examined the effects of superoxide on the development and maintenance of mechanical allodynia, as well as its contribution to central sensitization in a superoxide-rich animal model of neuropathic pain. METHODS: Chronic post-ischemia pain (CPIP) was induced via the left hindpaw ischemia for 3 h, followed by reperfusion. Superoxide dismutase (4,000 U/kg, i.p.) was administered either 5 min before ischemia (BI), 5 min before reperfusion (BR), or 3 days after reperfusion (3AR). Withdrawal thresholds of the four paws were measured to assess the mechanical allodynia and the effects of circulating xanthine oxidase (XO)-mediated superoxide production. In addition, we measured the levels of N-methyl D-aspartate receptor subunit 1 phosphorylation (p-NR1) in the ipsilateral and contralateral spinal cord (L4-6), by Western blotting, to examine the superoxide-mediated central sensitization. Superoxide production was assessed by allopurinol-sensitive, XO-mediated lipid peroxidation of the spinal cord and gastrocnemius muscles. RESULTS: Withdrawal thresholds of forepaws did not vary across the 7 days of testing. In the hindpaws, both ipsilateral and contralateral mechanical allodynia was most attenuated in the BR group, followed by the BI and 3AR groups. The degree of NR1 activation was in contrast to the changes in the withdrawal thresholds. CONCLUSIONS: These data suggest that superoxide is involved in the development and maintenance of mechanical allodynia, particularly via central sensitization in the spinal cord.

ABSTRACT

Percutaneous cardiopulmonary support (PCPS) is accepted as a very helpful mechanical support available for patients with cardiogenic shock unresponsive to medical treatment and intra-aortic balloon pump (IABP). Although the indication criteria or guidelines for the application of PCPS have not been established, several reports demonstrate that the early initiation of PCPS allows for good clinical outcomes in patients suffering cardiogenic shock. We experienced two patients that required PCPS before and after emergent cardiotomy to correct ventricular septal defect and left ventricular rupture due to myocardial ischemia, respectively. Herein, we report these cases to emphasize that the early application of PCPS is essential to improve the clinical outcomes in patients with severe cardiogenic shock.
