Associated Factors of Cholelithiasis among Younger Children with Sickle Cell Disease at the National Reference Center for Sickle Cell Disease in Brazzaville, Congo.

In the absence of management, they expose the patient to complications that can hinder the quality of life and sometimes even death.

[Cervical tumefaction in a child at Brazzaville University Hospital, Republic of the Congo].

A 8-year-old schoolgirl from West Africa with no previous pathological history was admitted to the haematology department of the Brazzaville University Hospital for the management of cervical adenopathy. The diagnosis of sinus histiocytosis or Destombes-Rosaï-Dorfman disease was retained and the patient was treated with PO corticosteroids (methylprednisolone 32 mg/d then 16 mg/d). Given the rarity and uncertain aetiopathogeny of this syndrome, treatment is poorly codified.

Neonatal Screening for Sickle Cell Disease in Congo.
