Age estimation using level of eyebrow and eyelash whitening.

BACKGROUND: The aim of this study was to determine whether eyebrow and eyelash whitening is an effective parameter in age estimation. MATERIAL AND METHODS: We evaluated 1545 patients. Age groups were 1-10, 11-20, 21-30, 31-40, 41-50, 51-60, 61-70, 71-80, and 81-90 years. Level of whitening was categorized as level 0: no whitening, level 1: 1-3 strands, level 2: 3-10 strands, level 3: 10 strands-2/3 whitening, level 4: >3/4 whitening. RESULTS: Mean age was 42.39 ± 20.01. While there was no eyebrow whitening in 87% of the subjects, level 4 whitening of eyebrows was observed in 0,8% of the subjects. There was no eyelash whitening in 97,7% of the subjects and no level 4 eyelash whitening was detected in any subject. Men had significantly more level 1, 2, 3, and 4 eyebrow whitening compared with women. There was no gender difference in terms of eyelash whitening level. There was no eyebrow and eyelash whitening in subjects age 1-40 years; whitening began in the 41-50 years age group and increased with age in other groups. Mean age was 39.59 ± 19.63 years in subjects with no eyebrow whitening; 59 years in level 1, 61 years in level 2, 63 years in level 3, and 69 years in level 4 eyebrow whitening. Mean age was 41.85 ± 19.87 in subjects with no eyelash whitening; and 63.57 ± 10.75 in those with whitening. CONCLUSIONS: Particularly after 41-50 years of age, level of eyebrow and eyelash whitening may be among a useful age estimation parameter.

Fatal ethyl and methyl alcohol-related poisoning in Ankara: A retrospective analysis of 10,720 cases between 2001 and 2011.

Methyl and ethyl alcohol poisoning are still responsible for high morbidity and mortality rates. The purpose of this retrospective study was to examine ethyl and methyl alcohol poisoning related deaths in Ankara and surrounding cities between 2001 and 2011 and compare them with previous studied conducted in Turkey and other countries. For this purpose, 10,720 medico-legal autopsy cases performed in Ankara Branch of the Council of Forensic Medicine were reviewed in terms of alcohol poisonings. The deaths due to methanol and ethanol poisoning were 74 (0.69% of all medico-legal autopsies performed) and the distribution among them was 35 (47.3%) for methanol poisoning and 39 (52.7%) for ethanol poisoning. Overwhelming majority of the cases were male (n = 67, 90.5%). The mean age of the victims was 44.9 ± 10.9 years and ranging from 21 to 92 years. The age group of 35-49 years was the mostly affected. Most of the cases were seen in 2004 (n = 12, 16.2%). The levels of postmortem blood alcohol levels were available for all cases and the mean alcohol levels were 322.8 ± 155.5 mg/dL ranging from 74 to 602 mg/dL for methanol and 396.8 ± 87.1 mg/dL and ranging from 136 to 608 mg/dL for ethanol. Early diagnosis is essential for successful treatment in methanol and ethanol poisoning. Besides increased awareness, more sensitive/specific diagnostic tools, and the prompt approach to the poisoned individual should be implemented in the hospitals.

Forensic and clinical carbon monoxide (CO) poisonings in Turkey: A detailed analysis.

Carbon monoxide (CO) is produced by incomplete combustion of organic compounds. Its intoxication usually results from inhalation of fumes from improper heating stoves, motor vehicles, or smoke from fires. It can reversibly bind various heme-containing proteins such as hemoglobin, myoglobin, cytochrome p450 and cytochrome oxidases. Among them, it has a high affinity for hemoglobin (230-270 times more avidly than oxygen) with which it forms carboxy-hemoglobin (HbCO) leading to decrease in oxygen-carrying capacity followed by end-organ hypoxia. A tissue hypoxia may then result in transient or permanent damage of important organs like central nervous system and even death. CO poisonings from different reasons are an important cause of morbidity and mortality in Turkey. The purpose of this study on CO poisonings in Turkey is to sum up and analyze the best available researches in both forensic and clinical toxicology fields. This was achieved by synthesizing the results of Turkish and English papers on forensic and clinical CO poisoning cases conducted in universities, institutes, hospitals and other official or private organizations in Turkey. Total of 47,523 medico-legal autopsy data collected from 9 different forensic medicine branches and emergency rooms in different year intervals were reviewed and 980 CO poisoning cases were determined. To calculate the frequency of CO poisoning within all the autopsies carried out and fatal poisoning cases, the number of cases was divided by the total number of medico-legal autopsies and total fatal poisoning cases. The mean age of cases, the source of CO gas, the most common seasons and months, gender, and blood HbCO levels were also taken into consideration if the data is available. Under the light of the findings, we may suggest that determination of affecting factors in CO poisoning is going to be one of the key subjects for planning preventive interventions.
