[Blood eosinophilia in Hodgkin's disease and radiation therapy (author's transl)].
The study of 186 cases (bed rests) of patients who have had a therapeutical radiotherapy shows that: those who have received a thoracic irradiation (neo-breast) do not release an appreciable hypereosinophilia (2% of cases); those who have received a pelvic irradiation (neo uterus, testicle, ovary) set a mode-rate hypereosinophilia (from 450 to 1 000 eosino/mm3) in 90% of cases; in Hodgkin's disease, 15% of the patients have an hypereosinophilia before any treatment; it increases to 34% after radiotherapy (cobalt 60); No difference has been shown either with the site of radiation (up or under the diaphragmatic) or with the age of the patients. On the other hand, a significative prognosis (survival greater than or equal to 5 years). From these observations, the authors propose some physiopathological hypothesis on the signification of hypereosinophilia in the course of therapeutical irradiations and Hodgkin's disease.

[Evaluation of the health status of nomadic and semi-nomadic populations of the Gourma-Mali: epidemiologic approach. II. Overall results and conclusions].
The authors report the main clues of morbidity, infant mortality, fecundity as well as the main endemic affections detected in the nomadic and seminomadic populations in Gourma that they have noticed during a descriptive epidemiological investigation. The worse clues of general morbidity come from children and among the ethnic groups studied from those of the Tamachèques and the Maures. Malaria, brucellosis, treponematosis (bejel) have a high rate of frequency. The few cases of tuberculosis detected incidentally encourage to search for the real effect of this affection. Urinary schistosomiasis is present in Gossi where durable ponds exist. Intestinal helminthiasis, tineas, and hemoglobinopathies seem not to be problems of public health in the area. Pterygiums and conjunctivitis are frequent while trachoma is absent in Gourma.

[Positive amebic immunofluorescence reaction during hepatic brucellosis].
While a brucellosis disease proved with bacteriological and serological tests, a serodiagnostic of amebiasis using the immunofluorescence techniques has been positive toward a dilution of 1/320. The authors think to have a false positive reaction in amebiasis. Even though the anatomopathological examination of the liver did not show any amoebiasis focus, we can see some histological lesions due to a present or an old brucellosis disease.

[Evaluation of the health status of nomadic and semi-nomadic populations of the Gourma-Mali: epidemiologic approach. I. Introduction, material and methods].
The authors set out the methodology and the practical way used in transverse epidemiological investigation with a descriptive aim which was made in natural area: Gourma-Mali. This part of the Sahel, hard to reach, is placed deep in the bend of the Niger river. The population is estimated at 100.000. The weather, ecological and human conditions have been unsettled by the drought. Sometimes, it was difficult to collect the data among the nomadic and seminomadic populations (Tamachèques, Peuls, Maures, Bellahs, Sonraïs). This investigation shows well the practical problems that this kind of study sets out in difficult bioclimatological and ethnological conditions.

[Malarial indices in 938 children and adolescents in the humid savanna area of the south of Mali].
The authors draw up "paludometric indications" by studying 938 children and youths, in the Kadiolo area, a humid savanna in the south of Mali, by the end of the dry season (beginning of March). These results give a global indication of 70.6% (cases of malaria) with 94.4% of P. falciparum and 9.96% cases of gametocytic indications. The numbers obtained far from the rainy season let us think that the annual transmission of malaria is continuous with a recrudescence in the humid season explaining largely the infantile mortality. The use of Nivaquine may easily protect these populations from the risk of malaria disease.

[Treatment of giardiasis with tinidazole].
Fifty patients stricken by giardiosis were treated by a single dose administration of Tinidazole -- 50 mg./kg. for children and 2 g. for adults per os. Fifteen days after treatment, 84 0/0 of the patients had negative coprologic exams for giardiosis. The product was well-tolerated by the digestive tract as was demonstrated by a coprologic examination for digested food reside; however, minor digestive inconveniences were noted in 87 0/0 of the patients. There were no perturbations of hematologic or hepatic tests. This product would thus appear to be a treatment of choice in the management of giardiosis.

[1 case of autochthonous strongyloidiasis].
About one case of massive strongyloidosis becoming out of any immunosuppressive treatment and without travel out of France in a 40 year-old-woman, the authors study the different possibilities of contamination and set the problem of a drug-resistance to Thiabendazole.

Subcutaneous abscess caused by Pleurophomopsis lignicola Petr: first case.
The dematiaceous coelomycete Pleurophomopsis lignicola Petr. was isolated repeatedly in pure culture from a subcutaneous abscess of the left leg in a farmer undergoing corticosteroid therapy for asthma gravis. To our knowledge, we report the first case involving this fungus as an aetiological agent of subcutaneous phaeohyphomycosis.

[Larva migrans].
Larbish, cutaneous larva migrans or creeping eruption, is a serpiginous cutaneous eruption caused by skin penetration of infective larva from various animal nematodes. Hookworms (Ancylostoma brasiliense, A. caninum) are the most common causative parasites. They live in the intestines of dogs and cats where their ova are deposited in the animal feces. In sandy and shady soil, when temperature and moisture are elevated, the ova hatch and mature into infective larva. Infection occurs when humans have contact with the infected soil. Infective larva penetrate the exposed skin of the body, commonly around the feet, hands and buttocks. In humans, the larva are not able to complete their natural cycle and remain trapped in the upper dermis of the skin. The disease is widespread in tropical or subtropical regions, especially along the coast on sandy beaches. The diagnosis is easy for the patient who is returning from a tropical or subtropical climate and gives a history of beach exposure. The characteristic skin lesion is a fissure or erythematous cord which is displaced a few millimeters each day in a serpiginous track. Scabies, the larva currens syndrome due to Strongyloides stercoralis, must be distinguished from other creeping eruptions and subcutaneous swelling lesions caused by other nematodes or myiasis. Medical treatments are justified because it shortens the duration of the natural evolution of the disease. Topical tiabendazole is safe for localized invasions, but prolonged treatment may be necessary. Oral thiabendazole treatment for three days is effective, but sometimes is associated with adverse effects. Trials using albendazole for one or four consecutive days appear more efficacious. More recent trials using ivermectine showed that a single oral dose can cure 100% of the patients; thus, this drug looks very promising as a new form of therapy. Individual prophylaxis consists of avoiding skin contact with soil which has been contaminated with dog or cat feces. Keeping dogs and cats off the beaches is illusory in tropical countries.
