Study of the use of lincomycin aerosols in dogs.

This paper reports studies on different aspects of the administration of lincomycin by aerosol in dogs.The purpose of the study was to determine the depth of penetration of the drug into the lungs and its transfer into the blood, urine and tissues when administered as an aerosol.Special consideration was given to the possibility of side effects at the level of the bronchial mucosa, since this study was viewed as preliminary to the use of the antibiotic in humans.

[Hepatitic amoebiasis (75 cases observed in Treichville University Hospital Abidjan--Ivory Coast) (author's transl)].

Reporting 75 original cases the authors review the clinical radiological and biological syndroma of hepatitic amoebiasis. They emphasize the recent advances in medical treatments which frequently give opportunity of avoiding surgery. But surgical intervention cannot be systematically discarded and has been necessary in 11 p. 100 of the reported cases. Drainage strengthens drugs efficiency. Antibiotherapy is generally useless.

[Takayasu-type arteriopathies. Apropos of 4 cases observed in Ivory Coast].

Report of 4 cases of Takayasu type arteriopathy observed in the internal medicine department of Treichville Hospital (Abidjan University). During a one year study the prevalence appeared high in African women: 0.4 p. 100 of all female admittances; 1.2 of the female patients under 35 years; 2 p. 100 of the females admitted for cardiovascular disease. Diagnosis criteria are studied: epidemiological criteria (young age, with a mean value of 21 years); clinical and biological criteria: high blood pressure associated with the absence of one or several arterial peripheric pulses and the presence of one or several arterial murmurs; biological criteria which are negative in the four cases this negativity indicating an occlusive phase. Aortography is the main diagnosis support, showing the situation of the lesions, permitting a topographic classification and giving the mechanisms of blood hypertension with, sometimes, a therapeutic consequence. In one case an inflammatory condition of the aorta has been observed at the media adventitia junction. A systematic study of etiology has brought no evidence of another possible diagnosis. Pathogenic role of tuberculosis is suspected but had not yet been demonstrated.

[Pericarditis in adults in Abidjan. Study of one hundred observations (author's transl)].

The goal of this work is to precise the respective aetiologic prevalence and the bases of diagnosis of pericarditis in Ivory Coast. The epidemiologic study has been done about 197 cases diagnosed between march 1972 and april 1978. These results are comparable to those collected previously in West Africa: the pericarditis is present in 1% of the patients admitted in the hospital and in 5.6% of the cardiovascular diseases of the unit of internal medicine in the Treichville Hospital (Abidjan). The semeiologic and evolutive study has been done with the 100 best documented records, with 90 acute and sub-acute pericarditis and 10 chronic pericarditis. The usual bases of diagnosis are used; the frequency of chest pain and signs of adiastole is emphasized. The aetiologic repartition is as follows: tuberculous 33%, septic 18%, benign acute pericarditis 15%, rheumatic 5%, uremic 13%, malignant 3%, undetermined 12%. These numbers are comparable to other author's numbers in West Africa. They confirm the important number of tuberculous and septic infections. These infections processus explain probably the frequency of constrictive pericarditis. However, the aetiology of constrictive pericarditis is often difficult to state precisely.U
