The livers of some larger fish such as shark, tuna and seabass have been reported to be responsible for a peculiar poisoning causing headaches and desquamation. This type of poisoning can also be induced by ingestion of the livers of the sea whale, the polar bear and the seal. Since these animals contain an extremely large quantity of vitamin A in their livers and the symptoms of poisoning in the patients resembled those of patients with acute hypervitaminosis A, the poisoning was believed to have been caused by excessive vitamin A intake. We observed an episode of acute fish liver intoxication in which 3 man experienced dizziness, headache, blurred vision, nausea, vomiting, fever, and desquamation after ingesting the liver of the grouper fish Cephalopholis boenak (C. boenak). One of the patients had full-blown symptoms and presented with a high fever, headache, dizziness, generalized aching pain, and superficial vesicles and bullae of the skin. The treatment was mainly supportive. In the follow-up period, he subsequently developed hair loss and diffuse peeling of the skin on his palms and soles. Acute fish liver intoxication is rare, especially in subtropical regions. Symptomatologically, the clinical pictures of these patients were comparable to acute hypervitaminosis A or retinoid intoxication. The average vitamin A content in the grouper (C. boenak) is high enough to cause acute vitamin A intoxication. Moreover, ethanol may play a potentiating role in this type of event.

Retinal detachment is an unusual complication of hypertensive disorder in pregnancy. It has been reported in 1% to 2% of patients with severe preeclampsia and in 10% of patients with eclampsia. Choroidal ischemia may be the cause of retinal detachment. We know that mild arteriolar spasm involving the bulbar conjunctival vessels has been observed in the normal pregnancy, but in pregnancy-induced hypertension the vasospasm may be severe and result in choroidal ischemia. Most patients with retinal detachment in pregnancy-induced hypertension have had full spontaneous resolution within a few weeks, and they did not have any sequelae. Medical treatment with antihypertensive drugs and steroids may be helpful. We report two rare cases of retinal detachment and persistent hypertension in association with postpartum eclampsia and post-cesarean section preeclampsia. These patients had normotension throughout pregnancy. Preeclampsia or eclampsia developed after delivery, and blurred vision, headache, and reduced vision accompanied serous retinal detachment. The serous retinal detachment disappeared within 3 weeks. Good outcomes were found in the follow-up examinations in both of these cases. For women who had been normotensive at the time of delivery and then complained in the postpartum period of blurred vision, headaches, nausea and vomiting, we should consider the possibility of retinal detachment and perform fundoscopy.

A 48-year-old man presented with bilateral blurred vision and visual field changes while prescribed amiodarone. Improvement of vision and visual field defects was documented within 3 weeks after discontinuation of the medication, and complete resolution occurred at 3 months. A unique feature of this amiodarone-associated optic neuropathy is the absence of any optic nerve edema.

The general clinical, ophthalmologic, and radiologic features of three patients with silent sinus syndrome are presented. All three patients were treated surgically. The cases of these patients illustrate the spectrum of presentation of silent sinus syndrome, including enophthalmos, hypophthalmos, transient vertical diplopia, lid retraction, lagophthalmos, and blurred vision. All patients had sinus disease, and all patients improved after surgery using functional endoscopic sinus surgery techniques. The protean manifestations of silent sinus syndrome can be identified, thereby allowing appropriate management.

We report the case of a 72-year-old female with pure autonomic failure, a rare entity, whose diagnosis of autonomic dysfunction was determined with a series of complementary tests. For approximately 2 years, the patient has been experiencing dizziness and a tendency to fall, a significant weight loss, generalized weakness, dysphagia, intestinal constipation, blurred vision, dry mouth, and changes in her voice. She underwent clinical assessment and laboratory tests (biochemical tests, chest X-ray, digestive endoscopy, colonoscopy, chest computed tomography, abdomen and pelvis computed tomography, abdominal ultrasound, and ambulatory blood pressure monitoring). Measurements of catecholamine and plasmatic renin activity were performed at rest and after physical exercise. Finally the patient underwent physiological and pharmacological autonomic tests that better diagnosed dysautonomia.

Endogenous endophthalmitis is a rare but devastating complication of bacteremia. Klebsiella pneumoniae is reported to be the leading organism of endogenous endophthalmitis in Taiwan, and the prognosis of endogenous Klebsiella pneumoniae endophthalmitis is extremely poor. A 46-year-old male patient was hospitalized because of fever, chills, and consciousness disturbance for 1 day. Meningitis was the impression by clinical presentation and findings of cerebrospinal fluid analysis. Parenteral ceftriaxone (4 g/day) and gentamicin (180 mg/day) were given, and his consciousness gradually cleared. On hospital day 6, he complained of blurred vision in both eyes and floaters in the left eye for 1 day. After ophthalmic examination, bilateral endogenous endophthalmitis was diagnosed. After aggressive treatment with intravitreal antibiotics and trans pars plana vitrectomy, the visual outcome of both eyes was better than those of other reported cases.

The safety and efficacy of endoluminal stenting in treating atherosclerotic vertebral artery disease was evaluated in 38 vessels in 32 patients. Indications for revascularization included diplopia (n = 4), blurred vision (n = 4), dizziness (n = 23), transient ischemic attacks (n = 4), drop attack (n = 1), gait disturbance (n = 1), headache (n = 2), and asymptomatic critical stenosis (n = 1). Success (< 20% residual diameter stenosis, without stroke or death) was achieved in all 32 patients (100%). One patient experienced a transient ischemic attack (TIA) 1 hr after the procedure. At follow-up (mean, 10.6 months), all patients (100%) were alive and 31/32 (97%) were asymptomatic. One patient (3%) had in-stent restenosis at 3.5 months and underwent successful balloon angioplasty. Endoluminal stenting of vertebral artery lesions is safe, effective, and durable as evidenced by the low recurrence rate. Primary stent placement is an attractive option for atherosclerotic vertebral artery stenotic lesions. Cathet Cardiovasc Intervent 2001;54:1-5.

A 47-year-old man reported becoming confused, disoriented, and anxious while driving his car. He recalled sweating and having blurred vision, palpitations, and a diffuse headache shortly before pulling to the side of the road and losing consciousness. Emergency service personnel arrived about 15 minutes later and administered a 50% solution of dextrose intravenously. On regaining consciousness, the patient had no weakness,shortness of breath, chest pain, or loss of bowel or bladder function. He had experienced a similar episode one week earlier and several others in the distant past. Each time, symptoms had been alleviated by eating.

Organophosphates are frequently used as insecticides in agricultural areas, therefore they may pose a risk for accidental exposure by dermal contact or through inhalation. We present the cases of eight young men, who worked unprotected and inexperienced with organophosphates. They were exposed dermally and developed mainly gastrointestinal symptoms and also diaphoresis, hypersalivation, blurred vision and miosis. One patient developed severe weakness, fasciculations, disorientation and sleepiness. All had low levels of plasma acetylcholinesterase. All were admitted to the hospital and received antidotal treatment of atropine and toxogonin. They were released after 48 hours in good physical condition. The hospital staff rapidly diagnosed the organophosphate intoxication; additional doctors and nurses were called to the emergency department. The patients were decontaminated in showers within the hospital. This case emphasizes the need for workers handling pesticides, to be supervised by an experienced person and the advantages of hospital drills in rapid diagnosis and preparedness to provide treatment to many patients.

Dysaesthesiae of the scalp and neurological abnormality after mobile phone use have been reported previously, but the roles of the phone per se or the radiations in causing these findings have been questioned. We report finding a neurological abnormality in a patient after accidental exposure of the left side of the face to mobile phone radiation [code division multiple access (CDMA)] from a down-powered mobile phone base station antenna. He had headaches, unilateral left blurred vision and pupil constriction, unilateral altered sensation on the forehead, and abnormalities of current perception thresholds on testing the left trigeminal ophthalmic nerve. His nerve function recovered during 6 months follow-up. His exposure was 0.015-0.06 mW/cm(2) over 1-2 h. The implications regarding health effects of radiofrequency radiation are discussed.
