A neonate with an immature, poorly demarcated retroperitoneal teratoma invading the aorta-vena cava space died immediately after surgery. Among 34 cases of retroperitoneal teratoma discovered during the first postnatal month, including one renal case and ours, eight can be considered malignant on the basis of histology in two cases and clinical course in six. Five of these tumors exhibited a significant immature component. In neonates, the proportion of malignant teratomas is greater for retroperitoneal tumors than for other sites: sacrum and coccyx, heart, neck, mediastinum, and abdomen. Evaluation of chemotherapy in teratomas with significant immature components is difficult because few of the patients of this small sample received such treatment. As in other sites, regardless of the degree of maturity, exeresis must be as complete as possible.
Natal teeth are present at birth, whereas neonatal teeth erupt during the first postnatal month. Mobile natal or neonatal teeth should be removed to prevent aspiration.
Four cases of failed adoptions of children from abroad are reported. Risk factors included advanced age of the adopting parents or adoptee and insufficient commitment on the part of the adopting parents who organized the adoption on their own without undergoing counselling. Prevention of adoption failures would require counselling by competent professionals and support groups (e.g., adopting parent groups, competent physicians) and mandatory review of adoption requests by an appropriate commission.
A case of portal hypertension in a five-year-old with multiple hydatid cysts in the liver is reported. Compression of the portal vein was the likely mechanism. Abdominal ultrasonography disclosed four hydatid cysts of which the largest was located in segments VII and VIII and caused compression of the supra-hepatic veins and inferior vena cava. Doppler ultrasonography showed continuous venous flow without triphasic modulation in the middle suprahepatic vein and inferior vena cava. Abdominal computed tomography demonstrated compression of the inferior vena cava and failed to visualize the suprahepatic veins. Upon surgery, evidence of hepatic venous statis was found. The child died 24 hours post-surgery. Budd-Chiari syndrome should be looked for routinely in patients with hydatid disease of the liver.
In neonatal disseminated hemangiomatosis, multiple immature capillary hemangiomas are widely distributed in the skin, mucous membranes, and internal organs including the liver, lungs, and larynx. In patients with life-threatening visceral involvement, corticosteroids or interferon may be required. A case in a female infant with tetralogy of Fallot is reported.
From 1980 through 1990, 45 cases of congenital syphilis, i.e., 15.5/10,000 births, were reported in French Guyana. Epidemiological and clinical characteristics of these cases were analyzed retrospectively. Most mothers were immigrants (32%) or members of the traditional Maroni community (60%). Congenital infections were often severe (symptomatic in 85% of cases and fatal in 33%). Treatment should be especially aggressive in patients infected with the human immunodeficiency virus.
There have been few reports of neonatal ischemic necrosis of the testis without torsion of the spermatic cord, which may be caused either by compression in utero or by transient torsion of the spermatic cord resolving spontaneously before surgery. The patient reported herein developed an inflammatory swelling of the right scrotum and an ecchymotic plaque over the left thigh at four days of age. Ischemic necrosis of the right testis without torsion was found upon surgery. When the patient was ten days of age, he developed an inflammatory swelling in the left scrotum; ischemic necrosis of the left testis without torsion was again found upon surgery. Thrombosis of the spermatic vessels was suspected. Postoperatively, ecchymotic and necrotic skin lesions developed, followed by pulmonary embolism and cerebral thrombosis. Outcome was fatal. Hematologic tests in the neonate and his parents established the diagnosis of inherited antithrombin III deficiency. Ischemic necrosis of the testes was thus probably due to hypercoagulability. No similar cases have been reported to date.
