Diatom test is routinely used by forensic pathologists in cases of bodies recovered from water, to identify the cause of death and the site of drowning. Studies have shown the presence of diatoms in organs of non drowning deaths as well.
This study was done to study identify the presence of diatoms in the liver of non drowning deaths.
Materials and Method
A total of 75 non drowning cases autopsied at a teaching hospital and a non teaching hospital in central Kerala between July, 2011 and September, 2012 with known causes of death were included in the study. The sample comprised of 62 males (82.7%) and 13 females (17.3%). Variables such as age, sex, diet preference and source of drinking water were collected. The liver was subjected to acid digestion and the presence of diatoms in the liver as well as the type was recorded.
This is a descriptive cross sectional study. Statistical analysis was done using the software IBM SPSS version 20.
Diatoms were found in the liver in 49 cases (65.4%). There was no statistically significant relation between the presence and absence of diatoms and the sex, age, dietary habits or drinking water source. One significant observation was that the pennates were significantly larger than the centrales (p 0.001). The mere presence of diatoms in the liver cannot be taken as evidence of drowning.
