This report describes the apparent 'resurrection' of a patient in an emergency department setting. Befittingly named the 'Lazarus phenomenon', the recovery of spontaneous circulation after cessation of cardiopulmonary resuscitation is an extremely rare occurrence that was first described in 1982 and has been mentioned only 38 times in the medical literature. Our patient's case is remarkable in that it helps illustrate many of the mechanisms of this rare phenomenon. It also serves as a reminder of our limitations in determining when to terminate cardiopulmonary resuscitation and suggests that cessation of cardiopulmonary resuscitation should be approached with more care. ⋯ Our patient's case clearly illustrates many of the proposed mechanisms for delayed return of spontaneous circulation including pulmonary hyper-inflation, hyperkalemia, delayed drug onset, and embolism dislodgement. Our patient represents a humbling and disturbing reminder that our medical acumen does not necessarily dictate the fate of our patients and that the decision to discontinue cardiopulmonary resuscitation should be approached with care by incorporating techniques such as end-tidal carbon dioxide, ventilator disconnect and passive monitoring.

Thrombotic thrombocytopenic purpura is a type of occlusive thrombotic microangiopathy that is not specific to pregnancy but occurs with an increased frequency during it. Prognosis of thrombotic thrombocytopenic purpura greatly depends on early diagnosis and treatment. As delivery does not generally cause resolution of thrombotic thrombocytopenic purpura, pregnancy termination is not initially considered, especially under 34 weeks, although it may be required under some conditions such as preeclampsia. Plasma therapy, including plasmapheresis, and steroids are used for treatment. In the event of an unfavorable course leading to cardiopulmonary arrest, effectiveness of cardiopulmonary resuscitation measures greatly depends on an early start of such measures. In pregnant patients, not only rapid implementation of these measures is required, but a decision should also be taken about the convenience of fetal delivery through a perimortem Cesarean section. ⋯ Despite the low prevalence of thrombotic thrombocytopenic purpura, the finding in a pregnant woman of the triad consisting of anemia, thrombocytopenia, and neurological changes should guide clinical diagnosis, and should prompt measurement of the metalloprotease ADAMTS-13 in order to rule out or confirm diagnosis of thrombotic thrombocytopenic purpura and evaluate the best therapeutic option. If cardiopulmonary arrest occurs in a woman with a gestational age of more than 24 weeks, a perimortem Cesarean section is advised if the patient has not recovered her pulse after the first four minutes.

Subarachnoid hemorrhage is one of the most feared acute neurologic events. Accurate diagnosis of subarachnoid hemorrhage is essential, and computed tomography of the brain is the first diagnostic imaging study. However, in rare circumstances, a similar appearance may occur in the absence of blood in the subarachnoid space. The contrast enhancement of subarachnoid space is a rare complication after lumbar percutaneous epidural neuroplasty, with, to the best of our knowledge, no previous report in the literature. ⋯ We report a rare case of contrast mimicking a subarachnoid hemorrhage after lumbar percutaneous epidural neuroplasty. The physician should keep in mind a rare case like this, and the supine position with head elevation is necessary to avoid a similar complication after lumbar percutaneous epidural neuroplasty.

We report a case of deliberate self-harm in which three three-inch nails were fired from a nail gun resulting in mandibular fixation and two penetrating injuries to the right cardiac ventricle. This combination of high-velocity penetrating injury has not been previously described. ⋯ This is the first reported case of a combination high-velocity penetrating nail gun injury to the face and the right cardiac ventricle. This rare case offers airway strategies to accommodate the surgical requirement for lung separation for penetrating chest trauma in a patient with iatrogenically limited mouth opening.

Spinal subarachnoid hemorrhage has many causes including trauma, vascular malformations, aneurysms, spinal cord tumors, coagulation abnormalities, use of anticoagulants, systemic lupus erythematosus, or Behçet's disease. We report on a rare case of a spontaneous spinal subarachnoid hemorrhage after severe coughing of unknown origin. To the best of our knowledge, this is the first report of spontaneous spinal subarachnoid hemorrhage after severe coughing. ⋯ Spontaneous spinal subarachnoid hemorrhage could be caused by rapid changes in intrathoracic and intra-abdominal pressure. Spontaneous subarachnoid hemorrhage should be considered when sudden back pain associated with severe headache develops. Even though emergent surgical decompression is necessary when the neurological state progressively deteriorates, conservative treatment with close monitoring of the symptoms can be recommended for patients with a stable neurological status.
