In Peri-Peri (Minas Gerais), an area endemic for Schistosoma mansoni, 591 inhabitants were examined. A coprological survey showed a prevalence of infection of 43.7%. After clinical examination 220 patients were distributed into three groups for treatment with oxamniquine; in Group 1, 19 children (2 to 15 years) were treated with a single oral dose of drug suspension around 20 mg/kg body weight; in Group 2, 47 children were treated orally with two 10 mg/kg doses with a 6- to 8-hour interval between them; in Group 3, 154 adults were treated with a single dose of about 15 mg/kg (capsules). The most frequent side effects were dizziness, drowsiness, and headache. No statistical difference in frequency of side effects was observed between Groups 1 and 2. Nevertheless, after treatment 32% of the patients in Group 1 complained of dizziness and 13% of headache, whereas in Group 2 the frequencies of these symptoms were 2% and 0%, respectively. Adults (Group 3) had a higher frequency of side effects, their chief complaints being dizziness and drowsiness. In Groups 1, 2, and 3, respectively, 73.7%, 62.2%, and 82.4% of the patients were cured. Statistical analysis did not show any difference in cure rates between children in Groups 1 and 2; however a significance was found when compared with the cure rate observed in adults, showing the drug to be more active in the latter group. In 61.8% of the 40 patients not cured a decrease of over 90% in the number of S. mansoni eggs/g feces was observed. From the data above oxamniquine seems to be an effective schistosomicidal drug suitable for use in endemic areas, although further studies are still needed.

A case of hypertensive intracerebellar hematoma surgically treated and cured was reported. The 41-year-old male had two cerebrovascular attacks with headache and vomiting followed by left hemiparesis. Drowsiness and dysarthria appeared the next day. The patient was admitted to a hospital, where right facial palsy, loss of right gag reflex and paralytic hemiplegia on the left side were noted. On the 7th day, the patient's consciousness became clear byt the other neurological evidences did not change. On the 14th day, bradycardia and central hyperventilation appeared and he became drowsy again. The patient was transferred to the authors' clinic. When the patient was admitted, he showed typical cerebellar signs such as nystagmus, ataxia, and slurring speech with pyramidal sign on left side and cranial nerves paralysis on right side, and also showed the changes of vital signs as a medullary syndrome in the late stage of the course. The vertebral angiogram revealed a space taking process in the right cerebellar hemisphere. The old blood (30g) was removed by suboccipital craniectomy. The hematoma cavity had a communication with the IVth ventricle through a small perforation in the medial wall of the hematoma. Spontaneour intracerebellar hematoma including of hypertensive origin is not rare in the reports of autopsy but surgically treated case has only rarely been reported. The main reason of few survivals should be in its fulminate course.

1. This report is concerned with 44 cases of acute viral encephalitides which were seen in the eight-year period 1965-72. 2. There is a significant difference in sex distribution: 63% males and 37% females. Nearly two-thirds of our patients were aged up to 30 years. There is no seasonal accumulation of incidence of the sporadic encephalitides. 3. The clinical diagnosis was based on "influenza-like" preliminary symptoms (25 patients), acute onset of neurological symptoms (30 patients) with signs of cerebral alterations like headache, drowsiness, confusion and epilepsy (22 patients), partly focal neurological signs (14 patients), inflammatory cerebro-spinal fluid alterations (36 patients) and other virus caused simultaneous diseases like myocarditis, hepatitis, pneumonia and exanthemata (19 patients). Alterations of blood sedimentation rate, number of white or red blood cells and differential blood count have no bearing on rapid diagnosis of acute viral encephalitides. Results of usual virological examinations often come to late for early diagnosis. Neuro-radiological procedures and isotope encephalography cannot help to get diagnosis in the initialphase of encephalitis. 4. 6 patients died, 5 had residual neurological deficit. 33 patients recovered completely though they partly had severe encephalitides. 5. There is no spezific treatment of acute viral encephalitides. Application of cortisone and antipyretic drugs is not indicated. 6. Most of the viral encephalitides may be classified when an extensive virological examination will be carried out.

Two cases of primary intracerebral malignant lymphoma were reported. Case 1 was a 42-year-old man who had been suffering from headache and mental disturbances for about 3 months prior to admission. These complaints progressed insidiously. He was admitted to our hospital on March 31, 1973. On neurological examinations he was in somnolence state and had neck rigidity, positive of Kernig's sign, disorientation and dyscalculia. Lumbar puncture gave a C.S.F. pressure of 240 mmH2O and the fluid contained 180 mg/dl of protein. A left vertebral angiogram via brachial artery demonstrated thalamic and cerebellar mass lesions. For the development of symptoms of increased intracranial pressure, a ventriculoperitoneal shunt operation was performed on April 7. A right carotid angiogram after ventriculoperitoneal shunt operation disclosed a frontal mass lesion. On May 2, a right frontal craniotomy was carried out and the frontal lobe was removed together with the tumors. After the operation his consciousness remained stupor. Thereafter consciousness and clinical pictures gradually worsened, and he died on May 30. Autopsy was performed, and gross examinations revealed tumors in the bilateral frontal and temporal lobes, right parietal lobe, and left cerebellar hemisphere. On coronal sections, there were neoplastic proliferation extending from the right thalamus to the putamen and a tumor in the right midbrain. No evidence of neoplastic proliferation was found outside the central nervous system. Microscopic examinations showed a diffuse proliferation of tumor cells with mitosis and polymorphism. The tumor was consisted of small lymphoid cells. Reticulin fibers were not found in the tumor with Watanabe's silver method. It was also unable to impregnate the tumor cells with silver carbonate. This case may be classified the primary interacerebral lymphosarcoma. Case 2 was a 48-year-old man, who was admitted to the hospital complaining of occipitalgia, speech disturbances and diffculty in walking. On neurological examinations, he had a right spastic hemiparesis and dyscalculia. A right carotid angiogram showed the frontal mass lesion. On April 18, a left frontal craniotomy was performed and frontal lobe was removed with the tumor. He made a good recovery from the operation and remained well for about 1 month. However, it culminated in a gradual diminution in the level of consciousness. Unfortunately, he died on June 20. No autopsy was performed. Histologically, the tumor cells had round or ovoid nuclei, mitosis and polymorphism. The perivascular arrangement of the tumor tissue showed tendency to confluence. There were reticulin fibers in the tumor tissue, particularly around the blood vessels. Microglial cells were not impregated with silver carbonate. It is supposed that this case belongs to the primary intracerebral "reticulum cells sarcoma-microglioma" described by Rubinstein or reticulum cell sarcoma. Both the case 1 and the case 2 should be filed to be malignant lymphoma in the wide category.

The demonstration that long-term administration of relatively low doses of clonidine decreased the responsiveness of blood vessels to vasodilator and vasoconstrictor drugs in animals led to its investigation in the prevention of migraine in man. Results of placebo-controlled and open therapeutic trials have shown that clonidine in low dosages (75 to 150 mug daily) is useful in preventing migraine headaches in about 30%-50% of patients. A 50% or greater reduction in headache frequency or headache indices has been reported in 40% of patients in controlled and open studies. Thus clonidine, like other drugs used in the interval therapy of migraine, can be expected to be effective in only a proportion of patients. Although clonidine has not been compared directly with other drugs used in the prophylactic treatment of migraine, the general clinical impression is that it is less effective then pizotifen or methysergide. Because it is relatively well tolerated at dosages of 75 to 150 mug daily it is worthy of a trial, particularly in patients considered to need prophylactic migraine therapy for the first time, and when migraine occurs in association with hypertension. At the dosages used in migraine prophylaxis, which are almost invariably lower than used in hypertension, clonidine does not cause hypotension and can be used in patients with cardiovascular disease. The principal side-effects are drowsiness and dry mouth which tend to diminish as treatment continues.

1 The psychotropic effects of a single oral dose of (--)-tryptophan (5 g) in human volunteers were investigated using a series of physiological and psychological tests. 2 Self-ratings of mood showed increase in drowsiness but no euphoria was detected. 3 Severe initial nausea occurred and headache increased; other bodily symptoms were unaffected. 4 Trptophan caused increased activity in the slow wavebands of the EEG but did not alter the other physiological measures. 5 The levels of total and free tryptophan in the plasma increased 8 and 20 fold respectively to peak levels 2 h after ingestion.

At their first visit to a hospital clinic 178 patients referred with a diagnosis of hypertension were given a self-administered questionnaire. They received a similar questionnaire 12 months later. Of the 178 patients 99 were not initially on treatment. Similarly 78 normotensive subjects were drawn randomly from the local population and sent a second questionnaire 10 months later. The symptoms at the first visit of the normotensive controls, the untreated hypertensive patients, and 477 patients on long-term treatment in the hypertension clinic were compared. Treated and untreated hypertensive patients complained more of nocturia and also of unsteadiness either on standing or in the morning. Treated hypertensives complained more of sleepiness, dry mouth, diarrhoea, and, in men, impotence and failure of ejaculation. Similarly, untreated hypertensives complained of excessive depression, blurred vision, and waking headache. Fifty-five of the normotensive subjects and 110 of the newly referred hypertensive patients responded to the second questionnaire. The proportions losing and gaining symptoms were calculated together with the proportions always complaining and never complaining of a symptom. Hypertensive patients tended to lose the complaints of unsteadiness and headache but to gain the symptoms of vivid dreams, a slow walking pace, and diarrhoea. The net improvement for a symptom was defined as the excess of patients who lost a symptom over those who gained the symptom, expressed as a percentage. Over the follow-up period the control subjects had a net improvement averaged over 14 symptoms of +2-4 per cent. A similar result was obtained for the hypertensive patients of +2-0 per cent, the symptoms lost being balanced by those gained. The changes in symptoms with time were related to the changes in blood pressure and it is suggested that only headache, 'unsteadiness, lightheadedness, or faintness' and nocturia can actually result from raised blood pressure and then only in a proportion of patients complaining of these symptoms.

In adverse drug reaction studies proper control over 'Back ground noise' is to be maintained to avoid erroneous conclusions to be drawn for adverse drug effects. Healthy volunteers, not taking any medication, were surveyed by a questionnaire to obtain data on the occurrence of any symptoms, often ascribed to side effects of drugs. Only 62 subjects out of a total of 236 (26.27%) stated experiencing none of these symptoms during the previous 3 days. The remaining subjects reported some symptoms, with an median number of symptoms experienced per person being 2; the most common being fatigue; headache, inability to concentrate and excessive sleepiness.

The neurophysiologic correlates of explosive rage and violence are uncertain and controversial. We recorded 17-channel electroencephalograms (EEGs), brainstem auditory-evoked potentials (BAEPs), and long-latency auditory-event-related potentials (AEPs) in 23 patients with impulsive, aggressive and violent behavior satisfying criteria for episodic-dyscontrol syndrome. Most patients also satisfied criteria for intermittent explosive disorder, although some had had conduct disorders in childhood or had previously used psychoactive substances. Sixteen of 23 patients had normal EEGs, while 7 had diffuse or focal slowing not ascribable to drowsiness or the effects of medication. They differed significantly from 20 age-matched patients with headaches, of whom 1 had an abnormal EEG (chi 2 = 4.68, p < 0.05), and from 24 depressed patients, all of whose EEGs were normal (chi 2 = 4.83, p < 0.05). Patients and normal control subjects did not differ in BAEP latencies. N100 and P160 AEP amplitudes were lower in episodic-dyscontrol patients than in control, but the difference was not significant. These findings suggest that non-specific cerebral dysfunction and EEG changes may be associated with disordered impulse or behavior control. Episodic dyscontrol may be associated with other evidence of minimal brain dysfunction.

At a time when Fansimef, the fixed combination of mefloquine, sulfadoxine and pyrimethamine was considered for prophylaxis of falciparum malaria, a randomized double-blind study comparing the efficacy and tolerability of Fansimef with that of Lariam (mefloquine), Fansidar, chloroquine and placebo in malaria prophylaxis was performed in Thailand from July 1987 to January 1988. The study population of 602 adult males was recruited in Pak Tongchai District, some 360 km North-East of Bangkok, where multiresistant P. falciparum is endemic. All active treatments and placebo were given once weekly for 24 weeks with doses as follows: Fansimef: 125 mg mefloquine + 250 mg sulfadoxine + 12.5 mg pyrimethamine (1 half-strength tablet); Lariam: 125 mg mefloquine (1 half-strength tablet); Fansidar: 500 mg sulfadoxine + 25 mg pyrimethamine; chloroquine; 300 mg. A loading dose of 2 half-strength tablets was given in the Fansimef group in weeks 1 and 2 and in the Lariam group in weeks 1 to 4. The incidence of acute episodes of P. falciparum per 100 person months of prophylaxis was 0.17 each in the Fansimef and the Lariam groups, 1.18 in the Fansidar group, 0.69 in the chloroquine group and 0.64 in the placebo group (differences statistically not significant). Clinically adverse events were reported by 170 subjects (Fansimef 28, Lariam 29, Fansidar 41, choroquine 43, placebo 29; differences statistically not significant). The most frequent adverse events in all groups were headache, sleepiness, dizziness and weakness.(ABSTRACT TRUNCATED AT 250 WORDS)
