Background:Several studies have reported the toxicological implications of inhalation of petroleum hydrocarbon fumes in animal models. But, there is certainly little or no documentation of the exposure to petroleum hydrocarbon fuel on oxidative stress levels in humans, unlike the pulmonary physiology. The present study was carried out to evaluate the effects of constituents of the hydrocarbon fuels on oxidative stress levels of the petrol fillers and tanker drivers. Methods: The study involved 165 males divided into three groups were the petrol fillers, tanker drivers and the controls. Case control data set was established wherein the control subjects are not exposed to hydrocarbon fuels with similar age. Serum samples of the subjects were collected and subjected for various biochemical assays. The enzymatic antioxidants such as superoxide dismutase, malondialdehyde a byproduct of lipid peroxidation and total antioxidant capacity of the individuals along with non-enzymatic antioxidant Vitamin A was estimated. Results: The results showed a no significant differences for age, body mass index, superoxide dismutase and levels of Malondialdehyde and total antioxidant capacity. But on the other hand, there is significant changes observed for total antioxidant capacity and vitamin A when exposed group is compared with control subject. Conclusion: It is evidential from the present study that prolonged exposure to petroleum hydrocarbon fumes leads to an increase in their oxidative stress in turn resulting broad spectrum of diseases. Hence, there is a raised need for public awareness about the health hazards in order to enable petrol attendants.

Background: Smoking is one of the preventable causes of disease in middle and low-income countries. This study was conducted in smokers and non-smokers to observe the changes in total count of leukocytes in cigarette smokers in relation to body mass index (BMI) and blood pressure (BP). Methods:The study populations were from different sources including diagnostic center and general hospital, and consisted of 58 smokers and 77 non-smokers, with a broad range of age groups. The variables considered for this study were the smoking status of current smokers and non-smokers, and blood samples of the subject, anthropometric data and also blood pressure data. Results: Total leukocytes in smokers were found to be higher than the non-smokers along with the increasing of lymphocytes. Leukocytes were also found to be increased with intensity of smoking in adult men and women. The BMI of the smokers showed decreasing trend compared to non-smokers. The relation between blood pressure and smoking was not well established, as there were only little changes on systolic blood pressure (SBP) of smokers found according to smoking intensity. Conclusion: Cigarette smoking has negative effects on leukocytes both in men and women smokers in terms of certain anthropometric parameters.

Background: Diurnal sequences of activities conducted at several locations visited by individuals have an impact on population exposure to air pollution. However, data on individual's movement with a fine time resolution is rare. Methods: In the current study, 399 children and adolescents (aged 11–18 years) from Isfahan city were asked to recall their 24-hour diary during winter and spring 2014-2015. Daily ventilation rates for individuals were calculated using Consolidated Human Activity Database (CHAD) and were subject to cosinor analysis. Results: There was a significant circadian rhythm in inhalation rate, outdoor time-spent and ambient NO2 pollution. The ANOVA of rhythm parameters showed a significant difference (P < 0.05) between gender groups and day types, whereas the difference between age groups and seasons was not significant. Analysis of results showed that increased NO2 pollution was concurrent with increased inhalation rate and outdoor time-spent. Inhalation rates obtained for population groups were 9.3, 11.6, 9.0 and 11.3 L/min for high school girls, high school boys, elementary girls and elementary boys, respectively. Elementary boys were at higher risk of exposure to air pollution. Boys spent more time outdoors and in traffic than girls. Respondents spent 89% of their time inside and 82% of their inside time at home. They also spent 10% of their time during a year in school. Respondents were exposed to cooking generated pollutants 11 times a week. Among them, 30% were exposed to second-hand smoke, and 86.3% reported in very good health. Conclusion: We concluded that actual exposure levels may be underestimated when the simple risk assessment method is implemented without the survey of fine time resolution spatiotemporal activity data.

Background: Overdoses with cardiovascular drugs are related with significant morbidity and mortality. Beta-adrenergic blockers, calcium-channel blockers (CCBs), thiazide, digoxin and angiotensin converting enzyme (ACE) inhibitors represent five of the most important classes of cardiovascular drugs. Overdoses with cardiovascular drugs are typically caused by exploratory ingestion by children or intentional ingestion by suicidal adults. As no study has been performed about poisoning with this kind of drug in Khuzestan, this study aimed to investigate the frequency of cardiovascular drug poisoning and its clinical features in patients presenting in Razi Hospital of Ahvaz from 2005 to 2009. Methods: A retrospective review of medical records of patients poisoned with cardiovascular who were treated at Clinical Toxicology Department was executed. A total of 70 poisoning cases referred to Razi Hospital were identified. These unselected cases included intentional, accidental, criminal and occupational circumstances. Beta-blocker poisoning, digital poisoning, calcium-channel blockers poisoning, ACE inhibitor poisoning, thiazide poisoning and poisoning with other cardiovascular drugs were evaluated on the basis of recorded data. Poisoning with one or several agents, time of admission, type of poisoned agents, sex, age, therapeutic intervention and mortality were investigated. Results: This study revealed that most of the people poisoned with cardiovascular drugs were females, single people and urban population. Most of the patients were 15-25 years old. Most poisoning was with beta blocker and calcium channel blockers. Their first symptom was headache and most of them needed ICU admission. Most of the patient ECGs were normal. There were 2 cases of death. Conclusion: This study revealed that continuous health care and the administration of the exact dose of drugs in the appropriate time and also developing of the toxicology centers seem necessary.

Background: 2, 4-dichlorophenoxyacetic acid, (2, 4-D) is a selective herbicide available as the acids, esters and several salts which vary in their chemical properties, environmental behaviour, and to a lesser extent toxicity. The salt and ester forms are derivatives of the parent acid. It is widely used as a weed killer. The 2, 4-D dimethylamine is one of the salts of this group. Case Presentation: We report a case of ingestion of 2, 4-D herbicide intentionally. The patient had presented in a local hospital but transferred to our hospital in a state of deep coma. CT scan head showed diffuse cerebral oedema. The patient recovered completely after treatment with forced alkaline diuresis. Discussion: Anticholinesterase compounds are the most commonly used insecticide and the commonest compound used as poison in India. This case report emphasizes that not all poisonings are caused by anticholinesterase compounds. The initial clinical manifestations of 2, 4-dichlorophenoxyacetic acid (2, 4-D) poisoning are very similar to alcohol, sedative drugs, or aromatic chlorinated hydrocarbons making it even more difficult for the treating physician to suspect poisoning due to these compounds. It is thus important to identify the correct compound for proper management. Prompt diagnosis and correct treatment can save the life of a patient. The poisoning is also sometimes confused with poisoning due to anticholinesterase compound. Conclusion: 2, 4-D is a poison which carries a high mortality. Prolonged coma, metabolic complications, skeletal muscle injury and myotonia are some of the complications of 2, 4-D. Forced alkaline diuresis resulted in saving our patient which otherwise had poor prognosis.

Background: Intra-corporeal concealment of illicit drugs known as ‘body packing’ is uncommonly reported. These drugs mainly comprise opium, heroin, cocaine, 3,4-methylenedioxymethamphetamine (ecstasy), amphetamines, and marijuana or hashish. Body packers may also be called swallowers, internal carriers, couriers or mules.
Although this practice is not new, its medical complications have always been a matter of concern. Some have reported improved packaging methods to deal with such complications. Body packing is an on-going drug smuggling method and authorities across the world are always on the alert.
Case Presentation: It has reported a case of death due to the effects of heroin concealed in a man who was attempting to smuggle the drug within his gastro-intestinal track.
According to forensic procedure of sudden unnatural death, the decedent had to accept a series of examination such as CT scan, autopsy and toxicological analysis. He was found dead from acute heroin intoxication due to the rupture of drug packet in the stomach.
Discussion: This case illustrates the challenges to forensic diagnosis in forensic medical methods in evaluation of potential drug packers and therefore it needs to consider all methods and finally best method involved in forensic diagnosis.
Conclusion: In conclusion, in body packer’s postmortem pathological signs are combined with evidence of the presence of drug pellets in the body as well as toxicological analysis in the ante-mortem history, and clinical reports. Toxicological analysis of the presence of the drug in body fluids, such as plasma, and in tissue extracts may not be of value when the level of the drug decreases after a period of metabolism.
