Takotsubo cardiomyopathy (TCM) is an underrecognized transient left ventricular dysfunction that mimics clinically an acute coronary syndrome. It has been linked to emotional stress and several clinical entities that provoke a catecholamine surge in the blood stream. We investigated the case of a young female patient who was admitted to the intensive care unit after a significant blood loss due to miscarriage. ⋯ As a result, TCM worsened further the general condition of the patient. There is a high possibility that TCM and hypovolemia can be closely related, and therefore, the treatment of hypovolemia can be adjusted to new standards. Because it has already been proved that TCM can be induced by emotional stress and various pathological entities, further investigations are necessary.

Our aim in this study was to use ultrasonography of internal jugular vein (IJV) instead of visual estimation by eye and to get more precise estimation of central venous pressure at supine position for estimating blood loss in healthy volunteers. ⋯ Although, the IJV collapse index was not found to be a useful parameter for evaluation of hypovolemia, cIJV LL is more valuable marker for the detection of blood loss at bedside.

The most frequent cardiac pathologies caused by electric shock are arrhythmias with a wide clinical picture ranging from sinus tachycardia to asystole. Cardiac mechanical complications secondary to electric shock have rarely been reported. ⋯ In this study, we have presented the rupture in the secondary chordae of the mitral anterior leaflet caused by low-voltage electrical trauma. To our knowledge, this is the first cardiac mechanical complication reported as a consequence of low-tension electrical trauma.

An increase in the intracranial pressure (ICP) might aggravate patient outcomes by inducing neurologic injuries. In patients with increased ICP the optic nerve sheath diameter (ONSD) increases due to its close association with the flow of cerebrospinal fluid. The present study was an attempt to evaluate the efficacy of sonographic ONSD in estimating ICP of patients who are candidates for lumbar puncture (LP). ⋯ The sonographic diameter of the optic nerve sheath might be considered a strong and accurate predicting factor for increased intracranial pressure.

Mediastinal hematoma is an uncommon finding in blunt chest trauma. It may be caused by aortic injury, by mediastinal vascular injury such as aortic injury, and by fractures of the sternum and vertebral column. A huge mediastinal hematoma can result in extrapericardial cardiac tamponade by compressing the adjacent organs. ⋯ The subxiphoid view of FAST can easily miss a mediastinal hematoma. For trauma patients with probable mediastinal injuries, we suggest doing an extended FAST with parasternal long-axis view. Alternatively, one should consider lowering the threshold of thoracic computed tomographic scan in patients with persistent symptoms because a missed mediastinal hematoma could be insidious and fatal.
