Case Reports
Impending cardiac tamponade caused by salt supplement in a hyponatremic patient with chronic kidney disease.
We documented a hyponatremic patient who developed imminent cardiac tamponade upon oral salt supplement. A 72-year-old diabetic woman had hemorrhagic stroke; pericardial effusion; and chronic kidney disease, stage IV. She developed hyponatremia (serum sodium level, 125 mmol/L), compatible with the syndrome of inappropriate antidiuretic hormone, and received oral salt supplement 9 g/d for 4 days. ⋯ Pig-tail drainage through pericardiocentesis was done, and the vital signs were stabilized. We found the production of pericardial effusion increased from 100 to 220 mL/d after oral salt supplement at 3 g/d was reassumed. We discuss the relationship between serum sodium levels, the dose of salt supplement and the accumulation of pericardial effusion.

Hiatus hernia (HH) is a frequent condition and is asymptomatic most of the time. Common symptoms can include epigastric pain, postprandial fullness, and nausea. We report a case of postprandial acute right and left heart failure caused by an intrathoracic stomach in a previously asymptomatic woman. ⋯ To the best of our knowledge, ours is the first report of both acute right and left heart failure due to an HH. The prompt placement of a nasogastric tube was lifesaving. We believe that the diagnosis of HH ought to be taken into consideration by emergency physicians and included in the differential diagnosis for acute postprandial heart failure.

The objective of this study is to determine whether creatine kinase-MB (CK-MB) index (CK-MBi) is useful in the evaluation of acute myocardial infarction (AMI) in patients with indeterminate troponin (Tn) in the emergency department (ED). ⋯ Initial results identify rare cases of AMI where CK-MBi is positive in the setting of indeterminate Tn. However, most patients with indeterminate Tn and positive CK-MBi were not judged to be having AMI. In most cases, CK-MBi is not positive with indeterminate Tn and when positive more commonly confuses the picture. This suggests CK-MBi could be eliminated in patients with indeterminate Tns.

A person consists of a variety of immune reactions as a result of bee stings, depending on his/her immunologic structure. A 49-year-old male patient was brought to the emergency department because of generalized tonic clonic seizure and loss of consciousness after an hour of wild bee bite from the anterior abdomen in a rural area. After cardiopulmonary resuscitation, he was admitted to intensive care unit. ⋯ The patient was diagnosed as SAH due to exposure to bee stings. The patient was treated for a month in an intensive care unit and discharged in a vegetative state. We present and discuss the case that had epileptic seizures and SAH after a bee bite, with the review of the literature.

The aim was to investigate the circadian and weekly variation in Chinese young patients with acute myocardial infarction (AMI). ⋯ There was a significant circadian variation with a peak from 00:01 to 06:00 in Chinese young patients with AMI. However, there was no significant weekly variation in these patients. The circadian periodicity may create new possibilities for disease prevention and medication prescription.
