Case ReportsGiant cell interstitial pneumonia: an unusual finding in a case of preoperative death.
Giant cell interstitial pneumonia (GIP) is an exceedingly rare, debatable, perplexing, occupational lung disease, which most commonly affects individuals exposed to hard metal dust. We report a case of GIP in a 60-year-old man, scheduled for coronary artery bypass graft surgery and died during induction of general anesthesia despite all efforts to resuscitate him. ⋯ Despite inaccessible data pertaining to the occupation, clinical history, and radiographic findings, the diagnosis was GIP due to the presence of intra-alveolar, bizarre, "cannibalistic" multinucleated giant cells-the histologic sine qua non of GIP. To the best of our knowledge, this is the first case report of GIP in the world literature that was diagnosed on histopathologic examination of lung tissue obtained at medicolegal autopsy.

"Dead in hot bathtub" phenomenon: accidental drowning or natural disease?
Sudden death in a hot bathtub occurs frequently in Japan, particularly among elderly people. This retrospective report describes the epidemiologic circumstances and physical findings at autopsy. In total, 268 victims were found unconscious or dead during tub bathing. ⋯ Annual mortality in Japan from accidental drowning in persons aged older than 75 years is 33 deaths per 100,000 population. However, this number may be considerably underestimated as pathologists tend to regard lack of water inhalation as indicating a natural cause of death. Confusion in diagnosis remains consequent to the accidental and natural aspects of "dead in hot bathtub" phenomenon.

Retinal hemorrhage after cardiopulmonary resuscitation with chest compressions.
Retinal hemorrhages in children in the absence of risk factors are regarded to be pathognomonic of shaken baby syndrome or other nonaccidental injuries. The physician must decide whether the retinal hemorrhages in children without risk factors are due to abuse or cardiopulmonary resuscitation with chest compression (CPR-CC). The objective of this study was to determine if CPR-CC can lead to retinal hemorrhages in children. ⋯ The sixth patient had no risk factors and may have represented the only true case of retinal hemorrhages due to CPR-CC. Retinal hemorrhages are uncommon findings after CPR-CC. Retinal hemorrhages that are found after CPR-CC usually occur in the presence of other risk factors for hemorrhage with a mild hemorrhagic retinopathy in the posterior pole.

It is generally accepted that terms referring to specific craniocerebral injury mechanisms must be replaced by the more general term abusive head trauma (AHT). Although blunt impact trauma remains an essential part of AHT, it has received far less attention in the literature than shaken-impact injuries. The current article presents 19 confessed cases of a series of 47 highly suspected AHT cases. ⋯ The most important finding was a lucid interval (LI) in 3 blunt AHT cases. An LI does not seem to occur in shaking injuries because of the immediate and persistent effect of brain damage that such injuries involve. Therefore, LI makes it important to conduct a detailed investigation of the clinical course in time in suspected AHT cases.
