This paper focuses on recent developments in the areas of mode of action and clinical efficacy of mebendazole use since its introduction in 1974. Mebendazole blocks glucose uptake by adult intestinal-dwelling nematodes and cestodes and their tissue-dwelling larvae. The drug's poor absorption does not appear to affect clinical efficacy except in the treatment of systemic helminth infections. Mebendazole has been found to be ovicidal for the eggs of roundworm, hookworm, and whipworm with the disadvantages of cost and long duration of therapy; it is also considered the best drug for the treatment of trichuriasis. Among its nonapproved uses, it shows promise in the treatment of capillariasis and hydatid disease. Further investigation is needed to establish its role in the treatment of taeniasis, Hymenolepsis nana, Strongyloidiasis, Trichinosis, and Dipetalonema perstans. Side effects such as diarrhea, abdominal pain, headache, and dizziness have been reported on rare occasions.

The authors report the results of the trichinosis epidemic which occurred in the southern suburbs of Paris in January 1976. 125 patients from a total of 65 families were affected. The major signs: oedema of the face and eyelids, fever and myalgia, were commonly found. There were even laboratory abnormalities with eosinophilia, increase in muscle enzymes and positive specific serology. The course over a period of months was very favourable. There were no deaths. The most severe symptoms rapidly regressed. Only myalgia and headache, and above all fatugie, persisted for 3 to 4 months, in the adults. The biological course was marked by the disappearance in one month of the majority of the disturbances seen in the acute phase, apart from the eosinophilia and serological findings which remained pathological after one year in a number of cases. The particular aetiology, due to horsemeat, may be explained by modern industrial rearing techniques and the complexity of current commercial circuits.

The focus of trichinellosis was presented comprising 28 patients and resulting from consumption of the wild boar meat. Early confirmation of trichinellosis diagnosis in the first case (index case) and an accurate epidemiological analysis established that the patients became infected with Trichinella spiralis strain originating from natural environment. A severe clinical course was disclosed in the index case, moderate course of trichinellosis in 11 patients, a mild course in 15 cases and an abortive course in one patient. The most frequent trichinellosis symptoms included muscular pain (92.3% cases), fever above 38 degrees C (62.2% cases), conjunctivitis (53.3%), periorbital and facial oedema (42.9% cases); headaches and excessive sweating were less frequent (35.8%), while diarrhoea, hemorrhages to the fingernail beds and skin rush were noted in single cases only. No leukocytosis was detected in 15 patients (53.5%) and number of acidophilic granulocytes was normal in 8 patients (28.5%) including 5 patients with moderate course of the disease. Also, no full correlation was detected between severity of the clinical course and anti-Trichinella antibody titres. Increased activity of a muscular enzymes creatine kinase (CPK) could be detected in 27 patients and increased activity of lactic acid dehydrogenase (LDH) in 9 patients. The increase in muscle enzyme activity (CPK in particular) in some patients failed to correlate with the severity of the clinical course. In 10 patients parasitological and histological study of muscle tissue biopsies was performed to determine intensity of the invasion and the character of pathomorphological lesions.

It is still a matter of debate whether or not infection with Trichinella spiralis is followed by long lasting sequelae. A common source epidemic of trichinosis which occurred in Bitburg, FRG, in October 1982 gave us the opportunity of performing a controlled cohort study (171 patients and 51 controls). 145 patients and 44 controls completed the 3 year follow-up. Complaints persisted in 36% of patients aged less than 30 years and in 100% of patients aged greater than 50 years. Complaints in order of frequency were: muscular complaints 84%, ocular complaints 63%, cardiac complaints 48%, cephalgia 43%, neurological complaints 35%, gastrointestinal complaints 18%, m fatigue and weakness 18%, oedema 12% and fever less than 1%. IgG antibodies to T. spiralis were still present in all but 5 patients 3 years after infection. IgM antibodies were either low or absent. In our patients the frequency and pattern of complaints and the correlation to the specific antibody response provide evidence that trichinosis causes long-lasting disease. Yet, from our data we were unable to draw conclusions as to the causative pathophysiological mechanisms.

After the evaluation of 129 serum samples of persons who had ingested boar sausage infested by Trichinella spiralis, 48 individuals (40 adults and 8 children) with a mean age of 38.8 years were diagnosed of trichinosis. The incubation time was 17 days (range 2 to 44 days). The following clinical features were outstanding: facial and eyelid edema (50%), diffuse limb myalgia (43%), fever (37%), conjunctivitis (25%), headache (16%), and abdominal pain (16%). Remarkably, 33% of the diagnosed patients were asymptomatic. The diagnosis was made by an indirect immunofluorescence technique (IIF), which was considered as positive when the titer was higher than 1/20 after considering seroconversion at the beginning of the disease and after 4-6 weeks. Among laboratory abnormalities there was leukocytosis in 15 patients and eosinophilia in 37. The GOT, GPT and CPK enzymes were only slightly increased in a small proportion of patients (8, 10, and 31%, respectively). Forty patients were treated with thiabendazole, associated or not to corticosteroids, which was well tolerated. Eight patients were not treated. One year after the diagnosis a new laboratory control was undertaken in 43 patients (all asymptomatic). Eosinophilia was still present in 12, and the titers against Trichinella were high in all. However, the percentage of the titer was smaller than at the beginning of the outbreak.

The clinical and epidemiological aspects of the largest Italian outbreak of human trichinellosis which occurred in Northern Italy in August 1986 are reported. About 300 people who ate raw horse meat were involved. The clinical and biological aspects of 161 patients were studied. None died. The causal parasite, isolated from a patient, was identified through isoenzymatic typing as Trichinella nelsoni. Fever, oedema, myalgia and headache were the most common signs and symptoms. The Fluorescent Antibody Test (FAT) proved positive for 96 percent of the patients showing clinical manifestations. Essential laboratory data are reported.

Acute trichinosis can be followed by a chronic stage. Myalgia is the main clinical symptom in the chronic course of the disease. From 19 patients with a history of acute trichinosis 2-42 years ago, 15 patients suffered from chronic myalgia. Other typical complaints of our patients in the chronic stage were opthalmodynia, burning of the eyes, headache and early fatigability.

In 1982, an epidemic of acute trichinosis occurred in Bitburg with 402 cases. The acute stage was observed and documented in 193 patients. The first signs of the disease appeared on average 17 days after eating trichina-containing meat. Muscle pain was reported by 85% of patients, lid and/or facial edema by 83%, gastrointestinal complaints by 62%, fever by 60%, flu-like symptoms by 56%, headache by 26%, eye complaints by 19%. Eosinophils were present in the blood of 92%. Trichinella antibodies were demonstrated in 98% of patients examined for them. Interstitial myositis was found in 90% of muscle biopsies (from 162 patients). Serious complications--thrombosis, myocarditis, pneumonia, hepatitis or meningism--occurred in 26 (13.5%) of the 193 patients. Even six months after onset of the disease 43% of patients were still not free of symptoms.

In 1963, acute trichinosis was recognized in four patients at the Ottawa Civic Hospital. One presented with cavernous sinus thrombosis and sixth nerve palsy. A second had a severe systemic infection with myocarditis; the signs of myocarditis appeared in the third week. Electrocardiographic abnormalities included T-wave flattening, prolongation of PR interval and QRS complex, and non-specific changes in 25%. Central nervous system involvement occurred in the second week with general symptoms (headache, delirium and psychotic behaviour), followed in the third week by focal signs (nerve palsy, convulsion, pareses and coma).The incidence of trichinosis in the U.S.A. fell from 15.9% before 1948 to 4.5% in the period 1948-1963. The Canadian incidence in the period from 1940 to 1943 was 5.6%. In a survey in Ottawa using the Baermann digestion and compression methods, four positive cases were found out of 500 diaphragms examined. These figures indicate the success of the public health regulations aimed at controlling trichinosis. A gastrocnemius muscle biopsy is still an invaluable diagnostic tool, especially in critically ill patients with negative skin tests and no eosinophilia.

An outbreak of trichinosis occurred in Purranque County, X Region, Chile, between october and november of 1992, which involved 36 persons. The incubation period, determined by the clinical picture and laboratory assays, fluctuated between 10 and 12 days. Myalgias (88.9%) and palpebral oedema (86.1%), were the most important symptoms, followed by fever (44.4%) and headache (33.3%). Eosinophils count ranged from two to 42% the first week, and this value raised to 55% the second week of the outbreak. Anti-Trichinella spiralis antibodies were determined by some serological tests such as: precipitin test (PT), bentonite flocculation test (BFT) and indirect hemagglutination test (IHAT) in sera from 28 patients at the beginning of the outbreak. PT was positive in 46.4% of the cases, followed by IHAT (21.4%) and BFT (3.6%). After 15 days, the three tests were performed in sera from 12 patients. At that time, the positivity was elevated in all of them: PT (100.0%), BFT (66.7%) and IHAT (91.7%). It is believed that the outbreak had its origin in infected pork meat that was consumed raw or insufficiently cooked without a previous veterinary inspection.
