A 19-year old woman who developed rapid nausea, vomiting, tachypnea, and alkalosis within 90 min of taking 3.25 g quinine S04 to induce abortion, was found to have an elevated anion gap and other electrolyte abnormalities. She was normovolemic, and had benign findings on drug screen except for quinine. Her abnormal laboratory values were high serum anion gap of 20 (normal 8-14), high urine anion gap of 171, low HC03- of 29 mEq/L, high Pa)@ of 130 mm Hg, alkalotic pH of 7.5, and hypokalemia of 2.6 mEq/L. Her hypokalemia was judged due to diuresis and vomiting. She was successfully treated with intravenous fluids and supportive care and was discharged on the third day. Quinine intoxication can also cause cinchonism, which is marked by tinnitus, vertigo, blurred vision and scotomata, and possible optic atrophy or death. The toxic dose is 2 g, and the lethal dose 8 g.

Accidental or intentional ingestion of carbofuran can produce a life-threatening syndrome that requires prompt diagnosis and treatment. This paper investigates unintentional carbofuran poisoning in farm workers. Thirteen patients were admitted to the emergency department with carbofuran poisoning between January 2002 and August 2004 (2 female, 11 male). The patients had been poisoned while mixing the liquid form of carbofuran with seeds. Their hands were red on admission. Complaints most commonly reported by the patients on admission were nausea, vomiting, headache, weakness, dizziness and blurred vision. The most commonly observed signs were tachycardia, tachypnea, salivation, miosis, elevated blood pressure, and fasciculation. Three patients were agitated and one was lethargic on admission. We reviewed the patients' medical charts retrospectively, as well as the demographic data, intoxication route, clinical and laboratory presentations, and outcomes. We made the diagnosis according to a compatible exposure history and clinical findings. The most commonly observed laboratory finding was hyperglycemia, which was found in 6 patients. Serum pseudocholinesterase level was low in only one patient. All the patients were cured and discharged from the hospital in good physical condition. Rapid onset, mild illness and quick recovery are typical characteristics of acute occupational carbofuran poisoning. We conclude that public health efforts should educate farm workers about the dangers of pesticide application so that its threat can be diminished.

Headache makes one of the most common side effects of frequently pesticide application. This is to be taken care of in rural areas. Headaches have been reported with the use of ivermectin, ivermectin-diethylcarbamazine, organophosphates, and also with the fungicide maneb and copper sulfate, carbofuran, hexonal, dioxin, methomyl and its salts, as well as rare cases of poisoning with the fungicide combination of propineb and cymoxanil. Headache often occurs after long term work with pesticides and/or in laboratories. There are numerous symptoms accompanying headache in pesticide poisoning the most common being elevated body temperature, lassitude, dizziness, irritability, nausea, vomiting, epigastric pain, diarrhea, myalgia, pains in the arms and legs, sleepiness, pains in joints, irritation of eyes/face/skin, sweating. Much less common are respiratory disturbances, tachycardia, tachypnea and other cardiac distur bances, fall of blood pressure, gastrointestinal discomforts, constipation, poor appetite, significant decrease in leukocyte count, anemia, albuminuria, azotemia, fasciculations, miosis, blurred vision, memory disturbances and other neurologic disturbances, postural tremor, signs of cerebral function damage, bradykinesia, etc.

Pneumocephalus is a clinical condition caused by dysbarism, trauma, and iatrogenic causes. The most common iatrogenic causes of pneumocephalus are major interventions as a neurosurgery and cardiovascular operations, endoscopy, and minor interventions as a peripheral and central venous access. Especially during insertion of central venous line and intravenous drug and fluid infusion, the venous air embolism may occur in emergency department. In these patients, retrograde pneumocephalus occurs as a result of the air entering the right atrium to the brain. Clinical effects of the air delivery rates are known to be more specific than the total amount of air. In general, intravenous administration of 300 to 500 mL air in the speed of 100 mL/min is considered to be lethal. Large amounts of air embolism can cause hypotension and acute circulatory collapse with intracardiac obstruction. The most common symptoms of venous air embolism are anxiety, dyspnea, chest pain, cyanosis, tachycardia, tachypnea, headache, confusion, agitation, syncope, slurred speech, blurred vision, seizures, and ataxia. The mortality of pneumocephalus caused by central venous catheters in patients presented with symptoms of focal neurologic was 8%, whereas the mortality of pneumocephalus in patients presented with encephalopathy was 36%. In our report, a case of pneumocephalus secondary to disconnection of catheter cap in chronic renal failure patient who has hemodialysis via catheter has been presented.
