Association of severe autosomal recessive osteopetrosis and Dandy-Walker syndrome with agenesis of the corpus callosum.

A severe form of autosomal recessive osteopetrosis associated with Dandy-Walker syndrome and agenesis of the corpus callosum is reported in a full-term boy born to consanguineous parents. The diagnosis was made shortly after birth. Clinical features were cranio-facial dysmorphy, macrocephaly, hepatosplenomegaly, severe anemia and thrombocytopenia. Skeletal radiographs revealed generalized increase in bone density and abnormal metaphyseal remodeling. Cranial ultrasonogram and computed tomography scan showed Dandy-Walker syndrome, agenesis of corpus callosum and hydrocephalus. The patient rapidly developed severe medullary deficiency and a severe pulmonary infection. He died at the age of 2 months. This association seems extremely rare and was not previously reported in the literature.

Abnormalities, Multiple↗

[Amniotic band syndrome. Case report].

Amniotic band syndrome is a rare fetal malformation involving limb ring strictions, cranio-facial and trunck abnormalities. The authors report a case of 5 months old infant with also facial cleft. The plastic reconstructive surgery leads to a better functional result. This affection represents a sporadic disease without genetic causes. The pregnancy ultrasonography visualise fetal abnormalities.

Adult↗

[Fistula of the 4th endobranchial pouch: a case report].

The congenital fistula of the 4th branchial pouch is rare. Clinical and therapeutic difficulties are often found. The authors describe a new case of fistula of the fourth endobronchial pouch and precise the embryogenesis, the clinical diagnosis and the surgical treatment.

Effect of ruminal inoculation of Isotricha alone or a mixed B-type fauna in a defaunated rumen on the digestion of a hay-maize diet (70:30) in sheep.

Two adult sheep (75 kg live weight) fitted with rumen cannulas were defaunated by the emptying method during the first period of the experiment. They were inoculated with the genus Isotricha alone during the second period, and with a mixed ciliate population (Entodinium, Eudiplodinium, Epidinium) during the third. They were fed a diet of grass hay (840 g) and pelleted maize grains (360 g) in 8 meals per day, every 3 h. Defaunation was successful and no accidental contamination occurred during the experiment. The protozoa had no significant effect on the volume of rumen digesta, nor on the turnover of the particulate phase. The addition of Isotricha and of the mixed fauna increased the ADF digestibility of the diet but, in the same animals, lowered the in sacco degradation of wheat straw. The ruminal pool sizes of dry matter (DM), organic matter (OM), nitrogen (N), neutral detergent fibre (NDF), acid detergent fibre (ADF) and acid lignin detergent (ADL) remained unchanged after protozoa inoculations. The concentration of total volatile fatty acids (VFA) was not altered by faunation with Isotricha or a mixed fauna. The molar proportion of acetate increased at the expense of all the other VFAs (mainly propionate with the mixed fauna). Correspondingly, the proportion of methane in the rumen gases increased and that of CO2 decreased in inoculated animals. The ammonia concentration was highest in animals with a mixed fauna and lowest in those inoculated with Isotricha alone. This trend is explained in terms of the specific effect of the different genera of protozoa on nitrogen metabolism.
