[Cytomegalic inclusion disease. Report of a case in a newborn]. / Enfermedad de inclusión citomegálica. Reporte de un recién nacido.

A clinical case of this disease in a newborn is reported. The clinical signs and laboratory results were typical and were confirmed by pathological studies. The modern literature stresses the high frequency of this disease, specially in the U.S.A. and England, where reports reach 4% in pregnant women and 1% of newborns with cytomegalic inclusion disease. We do not know its frequency in Mexico.

[Congenital syphilis, intrauterine radiologic diagnosis]. / Sífilis congénita, diagnóstico radiológico intrauterino.

The present work includes six cases of congenital syphilis that were diagnosed radiologically before birth in patients with positive syphilitic reactions who had not been given treatment during gestation. The x-ray diagnosis was mainly based on lesions of diaphyses and metaphyses of the long bones of the fetal skeleton that were identified in lateral projection of x-ray plates of the maternal abdomen. In all cases reported, x-ray plates were taken in the immediate post-partum period with confirmation of the bony lesions and at the same time, of the laboratory tests including blood picture and liver function test in 5 cases. Autopsy was practiced in one case.

[Multicystic kidney in the newborn]. / Riñón multiquístico en el recién nacido.

Fourteen cases of multicystic kidney were identified out of 153,825 births through five and a half years at the "Dr. Ignacio Morones Prieto" hospital in Monterrey, Nuevo León. The etiopathogenesis and heredity in this disease are not clear. An early diagnosis is possible following a careful abdominal examination. The left kidney is the one most frequently involved. The excretory urography only shows renal exclusion of the affected side; when the disease is of only one side there is good excretion of the opaque medium by the contralateral kidney. The kidney is substituted by an irregular mass made up of multiple cysts losing the aspects of a normal kidney. Microscopically, its architecture is completely lost and there is replacement by cysts and some occasional hypoplastic glomeruli. If the opposite kidney is not affected, the prognosis is good. Nephrectomy must be done. Differential diagnosis must be made with hydronephrosis, nephroblastoma and thrombosis of the renal vein.
