ABSTRACT

BACKGROUND: Organophosphates, pythyreoids, carbamate pesticides and fungicides are heavily used in agriculture. They may have dangerous effects on newborn health especially on immune system and growth via prenatal transmission by placenta or postnatal transmission by breastfeeding. METHODS: In 2015, 144 non-persistent pesticides in 64 milk samples of 32 mothers were studied by OuEChERS method in liquid chromatography/tandem mass spectrometer in neonatal Intensive Care Unit in Adana, a city in Cukurova region which is an important agricultural area in Turkey. RESULTS: Pesticides were detected in milk samples of 11 mothers (34.3%) and 21 (32.8%) of milk samples. In five mothers, fungicides (in 5/10 samples propicanozole-PP, in 4/10 samples bromucanozole-BM), in five mothers, organophosphates (in 10/10 samples primyphosphomethyl-PPM), in one mother, both organophosphates and fungicide (in 1/2 samples PPM and in 1/2 samples buprimate) were detected. However, the estimated daily intakes (EDI) were less than acceptable daily intakes (ADI) for PPM, PP and BM, respectively. CONCLUSIONS: Although pesticides levels in human milk did not exceed the ADIs, we suggest monitoring pesticides in human breast milk especially for newborn health.

ABSTRACT

OBJECTIVE: To determine the blood sevoflurane and desflurane concentrations during one-lung ventilation (OLV). DESIGN: Randomized, single-blind study. SETTING: Single university hospital. PARTICIPANTS: The study comprised 24 patients, 35 to 70 years old who were scheduled for either a major abdominal surgery or thoracotomy. INTERVENTIONS: The patients were divided into the following 4 groups: sevoflurane two-lung ventilation (TLV), sevoflurane OLV, desflurane TLV, and desflurane OLV. Vaporizers were set at 1.5% sevoflurane or 6% desflurane. MEASUREMENTS AND MAIN RESULTS: In the TLV groups, blood samples were taken in 10-minute intervals starting 40 minutes after the start of TLV (T1-T9) for blood gas analysis and gas chromatography. In the OLV groups, the first sample was collected at 40 minutes of TLV (T1), and other samples were collected in 10-minute intervals from the start of OLV (T2-T9). Saturation of peripheral oxygen (SpO2), hemodynamic variables, and inspired and end-tidal volatiles were recorded. The fraction uptake of the volatile agents (F) was calculated for each patient at the same time points. The mean arterial sevoflurane concentration in the sevoflurane OLV group at T1 decreased from 40.7 ± 4.4 to 30.2 ± 2.5 µg/mL at T3 (p = 0.014, 26% decrease). In the OLV desflurane group, the mean arterial desflurane concentration at T1 declined from 224.6 ± 44.8 to 159.8 ± 32 µg/mL at T3 (p=0.018, 29% decrease). However, the reduction of sevoflurane concentration compared with that of desflurane at T3 was not statistically significant (p = 0.31). In addition, the fraction uptake of the volatile agents values significantly increased at the start of OLV (p = 0.001). CONCLUSION: An OLV procedure causes a decrease in the both arterial and venous blood concentrations of sevoflurane and desflurane. This reduction is believed to be due to ventilation-perfusion mismatch.

ABSTRACT

In Cukurova region, pesticide poisonings still remain an unfortunate cause of death, which led to the present study. The autopsy records of Adana Branch of the Council of Forensic Medicine, between 2006 and 2008, were evaluated retrospectively. Deaths that were attributed to pesticide poisoning were included in the scope of the study to identify the type of pesticide, and etiology of intoxication. The frequency and distribution of intoxications were also analyzed in terms of sex and age. In the studied period, a total of 4199 autopsies were referred to the forensic toxicology laboratory for pesticide analysis. Seventy-two cases were positive for pesticide analysis. Of these, 42 (58.33%) were male and 30 (41.67%) were female, with a mean age of 38.8 ± 20.6 years. Among the inspected pesticides, endosulfan was found to be the most common with 47.2% of prevalence, followed by dichlorvos. This report showed that certain pesticides, endosulfan in particular, remains as common cause of poisonings in Cukurova region.

ABSTRACT

We determined and compared the levels of BHC and DDT isomers and metabolites and HCB in the adipose tissue of 82 cases of autopsies performed at the Morgue Department of Adana Branch of the Council of Forensic Medicine. The relationships between the age, gender, and body mass indexes of cases, and the accumulation of OCs residues were also investigated. Detectable concentrations of p,p'-DDE were found in 100% of adipose tissue samples. Concentrations of OCs in female adipose tissues were significantly higher than male adipose tissues (p < 0.05). The presented work is highly significant, being the first study pointing out the chronic exposure to organochlorine pesticides in Cukurova region.
