A 59-year-old man was admitted to our hospital with the history of epileptick attack of six years' duration. The seizure was associated with Jacksonian march starting in the right hand and then generalized. Todd's paresis of the right arm followed occasionally to the seizure. He was admitted to neurosurgical unit of other hospital in 1968 and 1971, but on each occasion no tumor or vascular abnormality was detected by extensive examiniations such as brain angiography, pneumoencephalography or brain scanning. He continued his hob as an engineer with anticonvulsant. He once lived in Manchuria in 1930s and had history of pulmonary tuberculosis. He was suffering from diabetes mellitus and chronic otitis media. Recentry he developed headache, forgetfulness, speech disturbance and right hemiparesis and was admitted to our department through psychiatric unit. On examination he was fully conscious but showed typical Gerstmann's syndrome and conduction aphasia. He also revealed bilateral choked disc, right hemiparesis, right hemihypesthesia and right homonymous hemianopsia. The cerebral angiograms and peneumoencephalogram suggested a left parietal cystic tumor. Brain scan with technetium 99m was negative. The spinal fluid was clear but showed slight pleocytosis (99/3/ml). Leucocyte count in the peripheral blood was 6600 per cubic meter with eosinophils of 3%. On craniotomy, small white patches were scattered at the subarachnoidal space suggesting of history of some meningitis. In the left parietooccipital region at Brodmann's area 19, a greyish yellow transparent cystic tumor was found in the subarachnoidal space which was confirmed to be one of the multilocular grape-like cystic tumors extending from area 19, gyrus angularis towards the arcuate fasciculus without continuity with the left lateral ventricle. Microscopic examination showed the racemosal type of cysticercus but no scolex was found. The fluid of the cysts was similar to the spinal fluid. He is totally symptome-free after five months' lapse from the operation except for sporadic spikes on the electroencephalogram. Although some neurosurgeons are against direct operation of the cerebral cysticercosis, we are sure it is possible to cure these patients suffering from chronic cysticercosis with tumor-like symptoms i.e. the tumor type of Stepien. But it is essential not to rupture the cysts during the operative procedure to avoid dissemination of worms which might lead to acute severe cerebral edema. Besides, echinococcus cysts harbouring many worms are often hardly differenciated macroscopically from the cysts of cysticercosis.

A total of 118,925 individuals in four Nigerian states was treated for onchocerciasis between February and December, 1991, using centralized and house-to-house distribution of ivermectin. Pre-treatment prevalences of the disease ranged between 28% and 90%. Only 0.7% of those treated reported adverse reactions within three days of treatment: 230 individuals (0.19%) had headache, 210 (0.17%) general body pains, 150 (0.12%) pruritus, 120 (0.10%) oedema, 80 (0.06%) fever, 20 (0.02%) dizziness, 15 (0.01%) vomiting, 10 (0.01%) diarrhoea, and 25 individuals (0.02%) noticed that they passed intestinal worms. Treatment in the endemic communities continues. The results show that mass treatment of onchocerciasis with ivermectin is quite safe and the drug's acceptability increases its potential as the drug of choice for control of onchocerciasis in Nigeria.

Angiostrongyliasis cantonensis is a disease commonly seen in Taiwan, especially in children during the summer rainy season. Most of the cases reported in other countries were adults and their clinical manifestations were different from children. Studies on special clinical characteristics of angiostrongyliasis cantonensis among 82 children in Taiwan were performed. Thirty-eight (46.3%) were male and 44 (53.7%) females, and 87% could be traced to a history of contact with the intermediate host, the giant African snail, Achatina fulica, which plays a major role in transmission. The incubation period (average: 13.2 days) was shorter in children than in adults (average: 16.5 days). In about one-third (30.5%) of the total cases, the clinical form was meningoencephalitis, which was higher than in adult cases seen in Thailand (5%). The most common clinical symptom was fever (91.5%), followed by vomiting and headache. The percentages of sixth and seventh cranial neuropathy associated with the disease were 19.5% and 11.0% respectively. Ophthalmologic fundoscopy showed that 25.0% with papilledema which was significantly higher than seen in adults (12%) in Thailand. Most of the cases in this study had peripheral leukocytosis (above 10,000/mm3) and eosinophilia (above 10%); the percentages were 82.9% and 84.1%, respectively. The worm recovery rate from cerebrospinal fluid by lumbar puncture of 82 cases was 41.5%; 141 worms were collected from one female patient using a pumping method. In the recent 2 years, albendazole and levamisole were used clinically with good result.

This three-phase study was designed to compare high dose ivermectin with a standard diethylcarbamazine (DEC) regimen for patient tolerability, potential to kill adult filaria, and duration of microfilarial suppression in 30 Haitian subjects with Wuchereria bancrofti microfilaremia. All were first given a 1-mg oral dose of ivermectin (phase 1) to reduce microfilaria densities. Participants were randomized into three groups: Group 1 received DEC (6mg/kg per day for 12 days), Group 2 received 200 mcg/kg of ivermectin, and Group 3 received 400 mcg/kg of ivermectin (200 mcg/kg per day for 2 days). All drug regimens were well tolerated with few adverse reactions. Most reactions occurred during phase I and consisted primarily of headache, fever, and myalgia. At the end of phase 1, 27 of 30 (90%) patients were microfilaria negative. During phase 2, four of the six men receiving DEC developed scrotal reactions suggesting killing adult worms; no such reactions were noted in 10 men receiving ivermectin (p less than 0.05). At one-year follow up (phase 3), all treatment groups had less than 10% return to pretreatment microfilaria levels. The mean percent of baseline microfilaria counts were for Group 1, 0.9% (range 0-5%); Group 2, 8.2% (range 0-31%); and Group 3, 3.8% (range 0-25%). Seven individuals in Group 1 were microfilaria-negative, while only one and three individuals were microfilaria-negative in Groups 2 and 3, respectively. These results suggest that DEC causes more damage to the adult worms and greater reduction in microfilaria densities than ivermectin, but that high doses of ivermectin may suppress microfilaremia in lymphatic filariasis for periods much longer than previously reported.

Angiostrongylus (Parastrongylus) cantonensis is the commonest cause of eosinophilic meningitis in the world. Infective third-stage larvae develop in slugs and snails. Humans are infected primarily in the central nervous system after ingesting an infected intermediate host. Damage by motile worms, inflammatory responses to foreign bodies, and possible toxicity of worm substances work in concert to produce the pathologic and clinical picture of neurologic angiostrongyliasis. This disease manifests itself by headache, paresthesias, generalized weakness, and occasionally visual disturbances and extraocular muscular paralysis. Eosinophilic pleocytosis is the major laboratory finding. Although the diagnosis of neurologic angiostrongyliasis is usually made clinically, serologic methods such as ELISA (enzyme-linked immunosorbent assay) can be helpful. Occasionally, living larvae can be identified histologically in the CSF, eye, or other tissue. There is no specific treatment for this disease. Corticosteroids may be useful to relieve increased intracranial pressure. The role of anthelmintic drugs, such as thiabendazole and ivermectin, is not yet known. The prognosis of neurologic angiostrongyliasis is usually good; however, fatal and chronic cases do occur. Appropriate preparation of food, control of mollusks and planarians, and elimination of rodents are important measures in limiting the further spread of eosinophilic meningitis caused by A. cantonensis.

A 14-year-old boy with a tetralogy of Fallot showed a subacute, progressive encephalopathy characterized by headache, stupor and coma. Death occurred three months after the beginning of the illness. Neuropathologic examination revealed diffuse foci of necrosis of the cerebral hemispheres and cerebellum, and the presence of the nematode Lagochilascaris minor in the parenchyma and in the cisterns at the base of the brain. In almost all 28 cases of human lagochilascaris previously reported, the worms were located in the soft tissues of the neck and throat, tonsils, mastoids and paranasal sinuses. This is the first reported case in which Lagochilascaris infected the brain. Since the life cycle of the worm is unknown the pathogenesis of the central nervous system lesions is obscure.

A study on the adverse reactions, occurring after treating microfilaremic patients infected with B. malayi, revealed that all reacted to a single oral dose of DEC (5 mg/kg). The major reactions were fever, headache, anorexia, abdominal pain, muscle and joint pains, nausea and vomiting. There seemed to be no association between the time of fever onset and microfilarial density, but the number of cases observed was too small to make any firm conclusion. There was a tendency for more severe reactions to occur in patients with higher microfilaria counts. Local reactions, probably due to destruction of adult worms, were seen in 3 patients. The reactions were serious enough to necessitate the patients spending approximately 48 hours in bed.

Praziquantel (2-cyclohexylcarbonyl-1,2,3,6,7,11b-hexahydro-4H-pyrazino[2,1-a]++ +isoquinolin- 4-one, EMBAY 8440, Biltricide) has been used in 4853 patients with Opisthorchis viverrini infection. 786 patients were treated as inpatients with extensive clinical evaluation and the rest were out-patients. A cure rate (evaluated with 5 faecal samples) of 100% was obtained in groups given 6 X 25 mg/kg on 2 days and 3 X 25 mg/kg on 1 day, while in groups given 2 X 25 mg/kg, 1 X 25 mg/kg and 1 X 40 mg/kg all on 1 day the cure rates were 88, 44 and 91%, respectively. With one sample evaluation the parasitological cure rate was 96% in further 96 patients excreting the geometric mean (GM) of 5394 eggs per gram (EPG) and receiving 1 X 40 mg/kg. Another 68 patients with an egg output of 26044 (GM/EPG) and treated with 1 X 50 mg/kg showed a cure rate of 97% by similar evaluation. Side effects were mild and transient and were more frequent in higher dosage groups. They included anorexia, nausea, vomiting, abdominal pain, epigastric pain, rumbling in the abdomen, diarrhoea, lassitude, myalgia, headache, dizziness, sleeplessness, sleepiness, "hot sensation", shortness of breath, and skin rash in a few cases. Headache (30.7%) was most common in the 6 X 25 mg/kg group. In 53 patients with severe jaundice the side effects were similar. There was no evidence of toxicity. Remarkable was one patient treated with 1 X 50 mg/kg who expelled 5636 O. viverrini worms, most of which were elongated and damaged. When a single dose is prescribed it should be given at bed time to reduce the side effect of sedation.

The authors study the results of a treatment of 700 cases of bilharziasis seen in Paris and in two foci in Togo, by oxamniquine, oltipraz or praziquantel. The three drugs are well tolerated; only a few mild side-effects were reported such as discomfort, nausea, headaches (two cases of acrodynia with oltipraz ). The three drugs are very efficacious in the case of schistosomiasis mansoni (85,5% success rate with oxamniquine, 92,9% with praziquantel, from 76,5 to 92% with oltipraz depending on the different strains) at day 180. As far as schistosomiasis haematobium is concerned, oltipraz and praziquantel have a 87,5% success rate with oltipraz and 80% with praziquantel; however, in the case of oltipraz , it is necessary to increase the dose. The action of praziquantel seems to be slower on Schistosoma haematobium than on S. mansoni. By the study of the evolution of antibodies, the fast action of praziquantel was noticed, explaining the peak of serological titers and of eosinophilia as early as day 10 after treatment; in the case of oltipraz , the apparition of this peak is only recorded at the 30th day. The slower effect of oltipraz on worms implicates not to judge its efficacy by too early controls.

The Katayama syndrome, the early stage of schistosomal disease, occurs 3 to 6 weeks after infection. The main symptoms are fever, urticaria, oedema and general malaise. Eosinophilia is a constant finding. The syndrome developed in a group of Dutch tourists after a visit in early November 1975 to the Omo National Park, southwest Ethiopia. Eight out of 10 infected persons became clinically ill. The incubation period varied from 4 to 41 days with a mean of 26 days. Pyrexia occurred in 6 patients, usually associated with headache and muscle pains; only to one patient the fever lasted for more than two weeks. Fever followed by oedema was present in one patient. Two patients were afebrile, one suffered from urticaria, the other from general malaise. Two visitors remained asymptomatic, but the results of serological tests showed that they were also infected. The liver function was disturbed in one patient during the febrile period and further deteriorated during treatment with niridazole. S. mansoni eggs were detected in small numbers in two patients, 6 months and 19 months after infection. Obviously the tourists harboured few adult worms. They probably had been infected by few cercariae; the possibility that they were infected by cercariae of a S. mansoni strain not well adapted to man was considered.
