[The epidemiological significance of neo-natal parasitism with microfilariae of Onchocerca volvulus (author's transl)].

Between April 1977 and June 1978, 214 babies born of 210 mothers infected with Onchocerciasis, were examined at the maternity of Po Hospital (Upper Volta). In four of them (1.9%) dermal microfilariae of Onchocerca volvulus were found during the first week after birth. In two other cases microfilariae were seen in the tissue of the umbilical cord. All specimens from placentas and amniotic fluid gave negative results. The infected babies were reexamined monthly monthly from 2 to 18 months, depending on the cases. One child remained positive until the 6th month follow-up. The base-line examination of 5.757 children less than 2 years old from different villages in the WHO Onchocerciasis Control Programme in the Volta River Basin Area showed that 1% of children less than one year old and 2% of children of 12 to 23 months old were carriers of dermal microfilariae. These results indicate that in meso- or hyperendemic areas children less than one year old and carriers of microfilariae of Onchocerca volbulus may have been infected in utero. The existence of such cases, in an area of vector control, does not prove a residual vector borne transmission.

[Fluorine osteosis caused by a very long-term niflumic acid treatment in 2 cases of rheumatoid arthritis].

An osteosclerosis opacifying the axial skeleton and affecting in particular all of the spine, was observed in two women aged 75 and 42 years who had been suffering from a rheumatoid arthritis developing between 15 and 26 years. It was traced to a chronic fluorine intoxication, stemming from the regular taking, for 10 years and 8 1/2 years, of a non cortisone, anti-inflammatory niflumic acid. This fluorine product has 3 atoms of fluor in its molecule (50.0 mg for a tablet of 250 mg). Its administration to control subjects proved the production of ionized fluor by way of the metabolism, and the accumulation of fluor in the organism. Rheumatoid polyarthritis and the prolonged corticotherapy (10 mg of prednisone per day for 21 years) cannot be dismissed as the origin of the severe demineralization of the limbs observed in the second patient, but the role of fluorine seems marked in the occurrence of this peripheral involvement with problems of mineralization and secondary hyperparathyroidisms. On the other hand, the absence of an intervertebral narrowing in the 2 patients, despite the very prolonged taking of cortisone (5 mg of prednisone per day for 15 years, for the 75-year-old patient) is perhaps a result of the fluorine.

[Intermittent rheumatism revealing a familial syndrome. Arthritis--urticarian eruptions--deafness: Muckle-Wells syndrome without kidney amylosis].

At a consultation with a 31-year-old man, motivated by painful episodes of joint pain that had started considerably earlier, a familial disease entity was discovered that included the three clinical signs of the Muckle and Wells syndrome : urticarial eruption, intermittent pain in the limbs originating in the joints, and bilateral deafness of perception. In spite of the absnece of renal amylosis, the similarity of the characteristics of these three elements, as well as the nature of the biochemical disturbances, and the mode of transmission, led the authors to consider these observations in the contest of this syndrome. The joint manifestations being indicative, the signs of this intermittent rheumatism are described, as well as the characteristics of the other disorders.

[Deafness in the Muckle-Wells syndrome].

Typical of the syndrome described by Muckle and Wells is a combination of progressive perceptive deafness appearing at various ages in a family, but usually at the same age in the same family, arthralgia, urticarious eruption and renal amyloidosis. The existence of incomplete forms, either without deafness or without renal amyloidosis should be known. This perceptive deafness is very probably due to lesion of the internal ear but the histological characteristics do not seem to be very clear at the present time. Finally, as certain of our observations show, in a few cases, conduction may be impaired, either in isolation, or associated with impairment of perception. Only an analysis of a large number of cases will enable the audiological characteristics of this curious syndrome to be defined.

[Osteomalcaia and chronic pancreatis. 5 cases].

The authors report five cases of an association between osteomalacia and chronic calcifying pancreatitis. The pancreatic involvement, which was pain-free in four patients, resulted in all cases in enzyme insufficiency with steatorrhoea. The deficiency-type osteopathy was highly vitamin sensitive. Aetiological study of these cases of osteomalacia revealed the constant presence of factors aggravating the vitamin deficiency, playing a role by increasing deficient intake or malabsorption, or by increasing Vitamin D requirements. It thus appears that hypovitaminosis D alone, of particular severity, was sufficient to result in the appearance of clinically evident osteomalacia. Such a vitamin deficiency, necessary when the intestinal mucosa is intact, is only rarely encountered, which accounts for the extreme rarity of osteomalacia in association with chronic pancreatic disorders.
