Complications from mydriatic and cycloplegic drugs are rare compared with their extensive use. Adverse effects are often related to dosage or other factors. The ocular complications include increased intraocular pressure, pigmentation of the conjunctiva and cornea, pigment in the anterior chamber, lacrimal duct blockage, macular edema, corneal endothelium damage, hyperemia, allergy, discomfort, and blurred vision. The systemic complications are those common to sympathomimetic and parasympatholytic drugs and include tachycardia, hypertension, headache, faintness. pallor, trembling, excessive sweating, palpitations, arrhythmias, confusion, hallucinations, drowsiness, ataxia, flushed skin, high fever, dysarthria, thirst, dry mouth, convulsions, disorientation, nervousness, coma, and death. An understanding of all possible side effects is of paramount importance to those using these drugs in the treatment of anticholinesterase poisoning. This review is intended as a ready reference to the adverse effects of mydriatic and cycloplegic drugs.

In 1989, 147 individuals in the West Midlands, UK, were infected with Q fever. Five years later, following anecdotal reports of fatigue, we used a questionnaire-based case-control study to determine the prevalence of chronic fatigue syndrome symptoms in this group. Replies from 71 patients were compared with those from 142 age- and sex-matched controls. Increased sweating (52.9% vs. 31.6%, p = 0.006), breathlessness (50.7% vs. 30.6%, p = 0.006), blurred vision (34.3% vs. 17.8%, p = 0.016) and undue tiredness (68.7% vs. 51.5%, p = 0.03) were found in controls compared to cases. These findings were similar to those in Australian abbatoir workers occupationally exposed to Q fever. CDC criteria for chronic fatigue syndrome were fulfilled by 42.3% of cases and 26% of controls. Using visual analogue scores, symptoms were more severe in cases than in controls. Our findings support the existence of a chronic fatigue state following acute Q fever, in a group of patients exposed just once to the organism, and in circumstances free of such confounding factors as lawsuits over compensation.

The authors reported a case of niclofolan intoxication occurred during the trial of clonorchiasis treatment. The case, a 15 years old Korean schoolboy, took niclofolan(Bilevon(R)) of total 473 mg(11 mg/kg) in 11 divided doses during 20 days. And the case suffered from neurologic symptoms such as severe headache, dizziness, nausea, vomiting, blurred vision, papilledema, retinal hemorrhage, an epsiode of seizure attack and elevated intracranial pressure, and hepatotoxic symptoms such as hepatomegaly, increased serum transaminases, and shoulder pain, excessive sweating and weight loss. Therapy was concentrated to the management of the elevated intracranial pressure. Hepatotoxic manifestations subsided within one month. The clinical signs related to elevated intracranial pressure persisted two months. Body weight regained after 2 months. And the symptoms of headache, dizziness and vomiting were complained intermittently until 4 months after onset. However, no subsequent clinical problems related with this episode has been noted until this record.

Pheochromocytoma occurs with a frequency estimated at 2-7 per 100,000 pregnant women. Unrecognized, and thus untreated pheochromocytoma is associated with very high (40-50%) maternal and fetal mortality. Pheochromocytoma occurs sporadically or as a family trait. Its presence should be suspected in women with paroxysmal or established hypertension, especially before the 20th week of pregnancy, accompanied by headaches and palpitations, and excessive sweating, muscle tremors, vomiting, anxiety, vasomotor disturbances and blurred vision. The variety of clinical presentations and rarity are the cause of not including the disease in differential diagnosis of hypertension in pregnancy. Biochemical tests are essential in the diagnosis of pheochromocytoma, and involving the assessment of methoxycatecholamine urinary excretion. The second step in the diagnostics is magnetic resonance imaging of adrenal glands. Adrenalectomy is the treatment of choice for pheochromocytoma with adrenal location, which depends on the timing of the tumor diagnosis. Conservative treatment for 10-14 days with pharmacological blockade of alpha-adrenergic receptors should precede the surgery. Early diagnosis and properly planned treatment of pheochromocytoma significantly reduces the risk to the mother and fetus.

Heat stroke (HS) is a medical emergency characterized by increased core body temperature with associated systemic inflammatory response leading to a syndrome of multi-organ damage in which encephalopathy predominates. We describe a case of a 29 year old male recruit presenting with altered mental status during military training in Puerto Rico. Associated symptoms included high grade fever, dizziness, nausea, vomiting, blurred vision and profuse sweating followed by loss of consciousness. Upon arrival to medical evaluation the patient was found with dry skin and depressed Glasgow Coma Score. Initial laboratories, clinical evolution of symptoms and imaging studies were consistent with the diagnosis of HS. Patient was managed with mechanical ventilatory support, intravenous fluids and external cooling measures. He was later discharged home without any neurological sequelae. To our knowledge this is the first documented case of HS in Puerto Rico.
