A role of nutrients in the onset of migraine and other gastrointestinal symptoms (vomiting, nausea, diarrhoea), skin reactions (rush, atopic dermatitis, Quincke'a edema), respiratory symptoms (bronchial asthma, cough, allergic rhinitis, polyps, congestion of the nasal mucosa), motion system disorders (jointache and edema), gynecological disorders (chronic and recurrent adnexitis), and sleep disorders together with emotional tension and behavioral disturbances has been assessed in 17 patients with atopy. Migraine attacks have been produced most frequently by cow milk (in 10 out of 17 patients), cabbage, flour and eggs in 5 patients, preservatives, cottage and Swiss cheese, porcine meat in 4 patients, colorants and chocolate in 3 patients, beef, strawberries, lemons and butter in 2 patients. Other nutrients produced headache in single patients. Migraine and other symptoms have diminished after an individual elimination diet. Recurrence has been noted after each consumption of allergen except one female patient with EEG abnormalities. Immunoglobulins E have been involved in headache-producing mechanism in 3 patients.

Both the systemic and local reactions caused by the immunization with the vaccine against diphtheria, tetanus and whooping cough were studied. Side-effects, 48 hours after the vaccination were determined in 730 children between the ages of two months and five years and 11 months. Over 13% of the children were free from side-effects. Eighty-seven percent of the children immunized showed the following side-effects in percentages of frequency: fever, 66.0%; malaise, 37.8%; loss of appetite, 25.0%; sleep disorders, 20.4%; vomiting, 7.9%; and continuous crying, 7.6%. With respect to local disturbances: pain, 41.6%; reddening, 28.0% and subcutaneous nodules, 20.1%. None of the children had convulsions, hypotonic episodes or immediate neurological damage. Two types of DTP vaccines, one from the Connaught (Canadian) Laboratory and another from the National Institute of Hygiene (Venezuelan) were used. No significant differences were found in the appearance of the side-effects between the both, except for localized pain (P less than 0.01) with the national vaccine. The results obtained in relation to age and the number of doses were: there was a significant increase of localized pain as ages increased (P less than 0.01). There were significantly greater number of localized pain and subcutaneous nodules with greater numbers of doses (P less than 0.01).

Fifty-two patients, most of whom had had daily headaches for years, were examined and treated. Among them there were 40 who originally had migraine, the others had vasomotor or post-contusional headaches. Average duration of the migraine was 21 years, of chronic headache 7.6 years. All patients had been taking analgesics of a mixed type regularly and for a long time, on average 35.6 tablets or suppositories weekly. All patients had taken more than three different drugs. After an observation period of 3-6 months for grading the headaches and registering the amount of drug intake, all patients were admitted to hospital when all analgesics were at once discontinued. Changing degrees of withdrawal symptoms were the rule: increased headaches, nausea, vomiting, tachycardia, sweating, sleep disorders, and in some also hallucinations and cerebral episodes. At the end of the hospital stay chronic headache had completely disappeared or markedly improved in 77% of patients. Even after an average of 16 months of subsequent observation, chronic headache continued to be significantly improved in 70% of patients. There was a significant reduction in frequency and intensity of attacks in the patients with originally typical migraine. Regular intake of analgesics of the mixed type induces chronic headaches. These are most commonly caused by ergotamine tartrate and aminophenol derivatives, while psychological and physical dependence on anti-migraine drugs is initiated and maintained by additional barbiturates, caffeine and codeine.

Outpatients with endogenous depression diagnosed according to the research diagnostic criteria of Feighner et al. were randomly referred to treatment with zimelidine (100 mg b.i.d., group Z) or maprotiline (75 mg b.i.d., group M). Patients who did not respond to treatment by days 28 were crossed over to the other drug. This preliminary report comprises results up to day 28 and includes antidepressive effect as rated by CPRS and globally, side effects, clinical chemistry and ECG. Ratings were double-blind at days 0, 7, 14 and 28, and a washout period of 4--7 days preceeded the trial. Group Z includes 27 and group M 28 patients with equal distribution of sex, age, duration of present episode, initial severity, etiology and previous course. There were 11 dropouts in group M and 5 in group Z due to side effects or treatment failure. On the other hand, 8 patients in group Z had to cross over to the other drug versus 2 in group M. According to the total CPRS score and the global score the antidepressive effect was somewhat better in group Z at 2 weeks but similar at 1 and 4 weeks. Group Z is less sedative but still seems to have a better anti-anxiety effect. Side effects were on a low level. There was a greater number of patients in group Z who complained of nausea, vomiting, loose stools, sleep disorder and sweating, and in group M dry mouth, drowsiness, dizziness and accomodation difficulties. Chemical analyses and ECG showed slight and inconsistent changes.

Amyloid deposits in leptomeningeal vessels, subarachnoid, subpial, and subependymal cerebrospinal regions, spinal ganglia, peripheral nerves, and some internal organs (predominantly heart and kidney) characterize a dominantly inherited disease in a Hungarian family. We found four definitely and three probably affected members in this family of 56 persons in four generations. Clinical features in all definitely diseased patients include disturbance of memory, psychomotor deceleration, ataxia, and hearing loss. In most patients there was temporary disorientation, migraine-like headache with vomiting, and tremor. Some patients had nystagmus, pyramidal signs with spastic paraparesis, hallucinations, urinary retention, and obstipation. Single patients had facial tics and sleep disorders. Progressive visual disturbance and clinically manifest polyneuropathy were absent. CSF protein was markedly elevated in all patients. CT showed characteristic symmetric calcification along the sylvian fissure; MRI after contrast administration showed prominent enhancement at the surface of the sylvian fissures, brainstem, and cerebellum. Autopsy data was available in three definitely affected patients and in one unaffected family member. Immunohistochemistry identified the amyloid deposits as of the AF (transthyretin, TTR) type; DNA studies revealed a novel TTR missense mutation at codon 18 (TTR Asp18Gly). According to clinical features, pathologic alterations, and molecular studies, this disease is a novel type of systemic familial amyloidosis with disease manifestation clinically restricted to the CNS. It is similar to the oculoleptomeningeal amyloidoses but can be clinically diagnosed by characteristic CTs and the absence of progressive visual impairment.

An open, randomized comparison of artemether-benflumetol (CGP 56 697; Novartis) with artesunate-mefloquine was conducted in 617 patients with acute uncomplicated multidrug-resistant falciparum malaria on the western border of Thailand. Both treatments rapidly and reliably cleared fever and parasitemia, and there was no significant difference in the initial therapeutic response parameters. Parasite genotyping was used to distinguish recrudescences from new infections. The 63-day cure rate for artesunate-mefloquine (94%) was significantly higher than the cure rate for artemether-benflumetol (81%) (P < 0.001). Both regimens were well tolerated. Nausea, vomiting, dizziness, sleep disorders, and other neurological side effects were between two and four times more common in the artesunate-mefloquine group than in the artemether-benflumetol group (P < 0.001). Artemether-benflumetol is effective and very well tolerated in the treatment of multidrug-resistant falciparum malaria. A higher dose than that used in the present study may improve efficacy.

In order to identify and analyse the factors associated with stress for the parents during day surgery, we performed a survey analysis of 568 parents whose children underwent surgery consecutively during an 18-month period. Of 368 parents who returned the questionnaire, (follow up rate=65%), 16% experienced the stress associated with day surgery as moderate to severe. The following factors had a significant positive association with the amount of stress: feeling of insufficient preparation (odds ratio; 95% confidence interval) 3. 34 (1.36-8.26; P=0.002), insecurity in nursing care at home 3.36 (1. 43-11.01; P=0.01), problems at home such as fever, vomiting, sleep disorders and others 3.15 (1.72-5.8; P=0.0007), problems with postoperative pain at home 2.43 (1.38-4.3); P=0.008), speaking a foreign language 2.28 (1.08-4.78); P < 0.0001) and no previous surgery 1.31 (0.76-2.27); P=0.03). Analysing these factors showed that often not the problems per se, but rather the insecurity in dealing with them contributed to the experienced stress. Conclusion In order to improve the quality of health care, more pronounced attention has to be given to the parents needs and expectations.

When peripheral decarboxylation is blocked by carbidopa or benserazide, the main metabolic pathway of levodopa is O-methylation by catechol-O-methyltransferase (COMT). Entacapone and tolcapone are new potent, selective and reversible nitrocatechol-type COMT inhibitors. Animal studies have demonstrated that entacapone mainly has a peripheral effect whereas tolcapone also inhibits O-methylation in the brain. In human volunteers, both entacapone and tolcapone dose-dependently inhibit the COMT activity in erythrocytes, improve the bioavailability and decrease the elimination of levodopa, and inhibit the formation of 3-O-methyldopa (3-OMD). Entacapone is administered with every scheduled dose of levodopa whereas tolcapone is administered 3 times daily. The different administration regimens for these agents are based on their different pharmacokinetic and pharmacodynamic profiles. Both entacapone and tolcapone enhance and extend the therapeutic effect of levodopa in patients with advanced and fluctuating Parkinson's disease. They prolong the duration of levodopa effect. Clinical studies show that they increase the daily ON time by an average 1 to 3 hours, improve the activities of daily living and allow daily levodopa dosage to be decreased. Correspondingly, they significantly reduce the daily OFF time. No comparative studies between entacapone and tolcapone have been performed. Tolcapone also appears to have a beneficial effect in patients with nonfluctuating Parkinson's disease. The main adverse effects of the COMT inhibitors are related to their dopaminergic and gastrointestinal effects. Enhancement of dopaminergic activity may cause an initial worsening of levodopa-induced adverse effects, such as dyskinesia, nausea, vomiting, orthostatic hypotension, sleep disorders and hallucinations. Levodopa dose adjustment is recommended to avoid these events. Tolcapone is associated with diarrhoea in about 16 to 18% of patients and entacapone in less than 10% of patients. Diarrhoea has led to discontinuation in 5 to 6% of patients treated with tolcapone and in 2.5% of those treated with entacapone. Urine discoloration to dark yellow or orange is related to the colour of COMT inhibitors and their metabolites. Elevated liver transaminase levels are reported in 1 to 3% of patients treated with tolcapone but very rarely, if at all, in patients treated with entacapone. The descriptions of acute, fatal fulminant hepatitis and potentially fatal neurological reactions, such as neuroleptic malignant syndrome and rhabdomyolysis, in association with tolcapone led to the suspension of its marketing authorisation in the European Community and Canada. In many other countries, the use of tolcapone is restricted to patients who are not responding satisfactorily to other therapies. Regular monitoring of liver enzymes is required if tolcapone is used. No such adverse reactions have so far been described for entacapone and no laboratory monitoring has been proposed. COMT inhibitors added to levodopa therapy are beneficial, particularly in patients with fluctuating disease. They may be combined with other antiparkinsonian drugs, such as dopamine agonists, selegiline and anticholinergics without adverse interactions. They provide a new treatment possibility in patients with Parkinson's disease who have problems with their present levodopa therapy.

Aspiration pneumonias occur more frequently than reported and, in many cases, the disease is not recognised. In hospitalised and institutionalised patients with predisposing diseases prompt diagnosis of this complication and correct preventive measures can drastically reduce the worsening of clinical conditions and the deaths due to aspiration pneumonia. Normal airway structure, effective defence mechanisms, and preventive measures are decisive in reducing aspiration episodes. An increased aspiration risk for food, fluids, medications, or secretions may lead to the development of pneumonia. Pneumonia is the most common respiratory complication in all stroke deaths and in mechanical ventilation patients. In addition, the increased incidence of aspiration pneumonia with aging may be a consequence of impairment of swallowing and the cough reflex. Dysphagia, compromised consciousness, invasive procedures, anaesthesia, insufficient oral care, sleep disorders, and vomiting are all risk factors. Aspiration pneumonia includes different characteristic syndromes based on the amount (massive, acute, chronic) and physical character of the aspirated material (acid, infected, lipoid), needing a different therapeutic approach. Chronic patients education and correct health care practices are the keys for preventing the events of aspiration. In patients at risk a clinical and instrumental assessment of dysphagia should be evaluated. Management includes the removal of etiologic factors (drugs, tubes, mobilisation, oral hygiene), supportive care, and in bacterial pneumonias a specific antibiotic therapy for community-acquired or nosocomial events.

OBJECTIVE: This study was designed to investigate the pharmacokinetic effects of coadministration of saquinavir/ritonavir with efavirenz at steady state. METHODS: Healthy volunteers in this open-label, two-arm, one-sequence, two-period crossover study (planned enrollment of 40 participants) were randomized to one of two treatment arms: those in Arm 1 were scheduled to receive saquinavir/ritonavir 1,000/100 mg orally twice daily for 29 days and efavirenz 600 mg orally once daily starting on day 15 and continuing through day 29; participants randomized to Arm 2 were to receive efavirenz once daily for 29 days and saquinavir/ritonavir 1,000/100 mg twice daily starting on day 15 through day 29. Assessments included vital signs, laboratory analyses, electrocardiography, and blood levels of total saquinavir, ritonavir, and efavirenz. Pharmacokinetic parameters included C(max) (maximum observed plasma concentration), t(max) (time to reach the maximum observed plasma concentration), (apparent elimination half-life), and AUC(0-tau) (area-under-the-plasma-concentration-time curve over one dosing interval). RESULTS: Eight participants (four in each arm) were enrolled; only two (one from each treatment arm) reached day 15 of the study and received the concurrent initial doses of saquinavir/ritonavir and efavirenz. The study was terminated prematurely after these two participants experienced nonserious adverse events. The participant in Arm 1 experienced mild abdominal discomfort, diarrhea, sleep disorder, and headache and the participant in Arm 2 experienced moderate-intensity abdominal pain and mild vomiting with leukocytosis accompanied by elevated pancreatic and hepatic enzymes (aspartate aminotransferase and alanine aminotransferase values of 2-fold and 3.5-fold the upper limit of normal, respectively). Both participants recovered completely following treatment discontinuation. Only limited pharmacokinetic data were generated on these two participants. CONCLUSIONS: The early termination of this study precluded drawing any definitive conclusions regarding the pharmacokinetics at steady state of coadministered saquinavir/ritonavir and efavirenz.
