We report epidemiologic, clinical, laboratory, and biopsy findings in 14 cases of nephropathia epidemica. The patients were between 19 and 49 years of age. The onset of the disease was characterized by high fever, nausea, headache, backache, abdominal pain, proteinuria, oliguria, hematuria, and uremia. The symptoms subsided rapidly during the polyuria phase, which followed the oliguria stage. Because of renal failure, hemodialysis was required in eight cases. Edema of eyelids, conjunctival injection and hemorrhages, transitory myopia, and acute glaucoma were the most common eye abnormalities. Renal biopsy specimens showed glomerular changes, with mild swelling of the epithelial cells of Bowman's capsule, thickening of the basement membrane of glomerular capillaries, glomerular adhesions, inflammatory cell infiltration, leukocytoclasis and hemorrhages in the interstitium, and eosinophilic hyaline degeneration and vacuolization of the epithelial cells of the proximal tubuli.

60,000 women in France have received RU 486 and a prostaglandin to induce abortion. In the late 1980's, clinical researchers assessed the safety and effectiveness of 600 mg of oral RU 486 in 2040 French women. 2 days later, health workers either injected 0.25-0.5mg of sulprostone or inserted a 1mg vaginal suppository of gemeprost in 1964 women who had not yet aborted. 96% experienced complete abortions. Physicians needed to conduct either a vacuum aspiration of dilation and curettage on the other 4%. RU 486 was most successful with 0.5mg of sulprostone, but these women also experienced considerable vaginal bleeding and pain. Overall uterine bleeding occurred for 8.9 days. The researchers recommended that adequate medical facilities be accessible to women using this method. Mild side effects were nausea, vomiting, and diarrhea. Efficacy and safety matched those of other early abortion methods. In April 1991, a grand multiparous women who smoked heavily and received RU 486 and a prostaglandin died--the 1st reported RU 486 related death. RU 486 may be able to treat fibroids, endometriosis, premenstrual syndrome, meningioma, hypertension, adrenal cancer, glaucoma, some forms of Cushing's syndrome, and breast cancer. The US Food and Drug Administration forbade the commercial import of RU 486 in 1989, even though it deemed RU 486 safe and effective. FDA considered the antiabortion view of the Bush Administration when making this decision. It made this decision despite the fact that abortion was still legal. RU 486 should be available soon for use as an abortifacient in the UK, the Netherlands, Sweden, Norway, Denmark, and Finland. These countries do not intent providing it to US women, however. Further the manufacturer is not willing to provide it to US researchers because it is afraid of antiabortion repercussions which may jeopardize WHO's approval of RU 486.

We studied the prevalence of migraine in low-tension glaucoma (LTG) and primary open-angle glaucoma (POAG). Seventy seven Japanese patients with LTG, 73 with POAG, and 75 normal subjects were randomly selected and tested with a headache questionnaire. The prevalence of headache with or without typical migrainous features (unilateral headache or ocular pain, nausea, vomiting, and visual disturbance before headache) was 51% in LTG, 42% in POAG, and 44% in normal patients. The prevalence of headache with two migrainous features or more (probable migraine) was 17% in LTG, 11% in POAG, and 12% in normal subjects. The prevalence of headache with three migrainous features (classical migraine) was 5% in LTG, 3% in POAG, and 3% in normal subjects. There was no statistically significant difference in the prevalence of any types of migraine between the three groups of patients (p greater than 0.05). These results suggest there is no significant relationship between migraine and LTG or POAG in Japanese patients.

The effect of a single oral dose of 2.5 mg bromocriptine on intraocular pressure in 20 glaucoma patients is reported. Intraocular pressure was significantly reduced (31%), the maximal response being after 4-6 hours. A decrease in blood pressure was also noticed, maximal reduction (5%) at 4 hours. Three patients experienced nausea and dizziness. Possibly the reducing effect of bromocriptine on intraocular pressure is mediated by the stimulation of intraocular dopamine receptors (DA2).

The authors administered a standardized headache questionnaire to 54 patients with low-tension glaucoma, 182 patients with primary open-angle glaucoma, 126 patients with ocular hypertension, and 493 normal subjects. Patients with low-tension glaucoma had headaches with or without features of migraine (unilateral headache, nausea or vomiting, or visual prodromata) more frequently than did any of the other groups. The higher prevalence of headache in low-tension glaucoma patients, who were usually elderly, was especially striking when their age was considered, since headaches are less common in elderly normal subjects than in young normal subjects. Headaches were present in 86% of elderly low-tension glaucoma patients (70 yr of age or older) but in only 64% of elderly normal subjects (P = 0.04) and only 59% of elderly ocular hypertensive patients (P = 0.02). Because migraine is an ischemic disorder, its possible association with low-tension glaucoma has etiologic and therapeutic implications.

Psychoactive drugs are often widely used before tolerance and dependence is fully appreciated. Tolerance to cannabis-induced cardiovascular and autonomic changes, decreased intraocular pressure, sleep and sleep EEG, mood and behavioral changes is acquired and, to a great degree, lost rapidly with optimal conditions. Mechanisms appear more functional than metabolic. Acquisition rate depends on dose and dose schedule. Dependence, manifested by withdrawal symptoms after as little as 7 days of THC administration, is characterized by irritability, restlessness, insomnia, anorexia, nausea, sweating, salivation, increased body temperature, altered sleep and waking EEG, tremor, and weight loss. Mild and transient in the 120 subjects studied, the syndrome was similar to sedative drug withdrawal. Tolerance to drug side effects can be useful. Tolerance to therapeutic effects or target symptoms poses problems. Clinical significance of dependence is difficult to assess since drug-seeking behavior has many determinants. Cannabis-induced super sensitivity should be considered wherever chronic drug administration is anticipated in conditions like epilepsy, glaucoma or chronic pain. Cannabis pharmacology suggests ways of minimizing tolerance and dependence problems.

We report ophthalmological findings in 15 cases of nephropathia epidemica. The patients, 13 men and 2 women, were 20 to 62 (mean 30) years of age. The onset of the disease was characterized by high fever, nausea, headache, abdominal pain, backache, somnolence, red throat, proteinuria, and oliguria. The symptoms subsided rapidly during the polyuria stage. Transitory myopia occurred in 8 patients (53%). Conjunctival injection and haemorrhages were seen in 3 patients (20%). One patient had acute glaucoma with oedema in the cornea and shallowing of the anterior chamber, with subsequent anterior uveitis and haemorrhages in the ocular fundus, and another patients had acute glaucoma. Three patients had photophobia which occurred in 2 patients without any glaucoma or anterior uveitis.

A patient with primary open-angle glaucoma (POAG) underwent a trabeculectomy according to Watson's technique. Postoperative intraocular pressure (IOP) ranged from 8 to 11 mm Hg. However, repeat slit lamp evaluation revealed the absence of bleb formation. Two months post-filtration surgery the patient developed the sudden onset of nausea, vomiting, supraorbital pain, and blurred vision. The IOP was 46 mm Hg and gonioscopy revealed a hyaline membrane covering a cyclodialysis cleft. A Nd:YAG laser was used to reopen the cleft, with normalization of IOP.

A 65-year-old aphake with a functioning filtration bleb underwent neodymium:YAG laser membranotomy. Shortly thereafter, he acutely developed pain, nausea, and visual blur with an intraocular pressure of 42 mm Hg. The mechanism of the acute glaucoma is believed to be occlusion of the fistula by herniated vitreous.

Pilocarpine, a parasympathomimetic drug used in the treatment of glaucoma, produces a variety of ocular and systemic adverse reactions. Ocular side effects include miosis, accommodative spasm, frontal headaches, twitching lids, conjunctival injection, cataractous changes, allergic reactions, iris cysts, retinal detachment, increased permeability of the blood-aqueous barrier, anterior chamber narrowing, and the potential for inducing an acute angle-closure attack. Systemic side effects include nausea, vomiting, tenesmus, abdominal spasm, salivation, lacrimation, sweating, pulmonary edema, and bronchial spasm. The systemic side effects can best be minimized initially through proper use of the medication and nasolacrimal occlusion. The Ocusert, a long-acting pilocarpine-incorporated ocular insert, is a recent advance in delivery technique that offers an adequate hypotensive action with fewer side effects. Pilopex is a promising new experimental pilocarpine polymer salt presently being studied in Israel. Photomydriasis, a process involving the use of a laser to enlarge miotic pupils also offers help for these patients. N-demethylated carbachol is a new parasympathomimetic drug currently under study for glaucoma therapy. Initial results show that it may have considerable ocular hypotensive action with fewer adverse effects.
