  The aim of this study was to describe the clinical findings and outcome in suicidal attempted due to intravenous injection of kerosene. This case series study was conducted in the Department of Internal Medicine, Shohada Ashayer Hospital, Khorramabad, Iran during 8 years. Ten IV drug addicts who intravenously injected themselves with Kerosene were collected. All patients admitted in ICU, completely monitored for cardiopulmonary status and consulted with pulmonologist, cardiologist, neurologist, anesthesiologist and dermatologist. Therapeutic decision including intubation, antibiotics therapy, and oxygen, correction of water and electrolyte disturbances was applied according patients condition. The data were analyzed with fisher-exact test. Nine (90%) patients were male, 1(10%) was female. All cases were attempted suicides and IV drug abusers. Mean age was 20.3±2 years. The patients’ mean arrival time to the hospital after poisoning was 1.1 h. Death of 5(50%) patients was related to the higher doses (>5 mL) of intravenous injection of kerosene, the most clinical findings were related to pulmonary involvement with pulmonary edema and subsequent cardiac and neurological complications and phlebitis due to IV injection. Intravenous kerosene injection causes major injury to the lungs, the organ bearing the first capillary bed encountered. Other complications including cardiac and neurological seems to be related to severe hypoxia and other metabolic disturbances due to lung injury. The amounts of kerosene were major determinants of lethality. Early and aggressive supportive care might be conducive to a favorable outcome with minimal residual pulmonary squeal at least in patients with injection of less than 5 mL of kerosene.

  Preeclampsia is a disease regarding with altered vascular reactivity leading to hypertension of the mother and metabolic alterations in the fetus. This study aimed to assess nitric oxide and bleeding time following administration of magnesium sulfate to preeclamtic patients compared to normotensive pregnant women. A total of 112 subjects (56 preeclamtic patients and 56 normotensive pregnant controls) were enrolled in this case-control study. Cases and controls were matched for age, BMI, gestational age, parity and gravidity. Total concentration of nitrite and nitrate (NOx) was measured before and during magnesium sulfate (MgSO4) treatment using a modified Griess-based method. Results: Systolic and diastolic blood pressures were significantly decreased during MgSO4 treatment in preeclamtic patients (p<0.0001). NOx levels were significantly increased in preeclamtic women after MgSO4 administration (33.7±18.5 vs. 50.2±21.6, p<0.0001) but it was not seen in normotensive parturients (52.4±28.9 vs. 57.3±21.7, p = 0.362). The bleeding time was scarcely increased following magnesium sulfate treatment in preeclamptic patients compared to normotensive pregnant women but it was not significant (p = 0.18). In addition, there was only a significantly reverse correlation between NOx levels and systolic or diastolic blood pressure in preeclamtic parturients after MgSO4 treatment (r = -0384; p = 0.003 and r = -0.29; p = 0.03, respectively). This study demonstrates that administrating MgSO4 to preeclamtic patients induced significant changes in NOx production which had a major role in modulating vasculature changes in preeclamsia.
