In a prospective study still in progress, infants with congenital cytomegalovirus (CMV) infection were followed with audiological, ophthalmological, neurological, and psychological tests; 10,328 infants were investigated within a 5-year period (1977-1982) by virus isolation in urine within the first week of life. Fifty (0.5%) had a congenital CMV infection. In this group four children turned out to have total deafness and a fifth possibly a mild hearing disorder. In one case the deafness was associated with severe mental retardation and spastic tetraplegia. The mother of the child had a primary CMV infection in the first trimester. In one of the other cases of severe deafness it could be proven that the mother had had a secondary CMV infection and in further two cases, presumed secondary infections. Prospective serological tests of the mothers would not have revealed more than one of the high risk pregnancies. The value of vaccination against congenital CMV infection is questioned. Screening of newborn infants for congenital CMV infection is recommended in order to reveal infants at high risk for deafness and make an early habilitation possible.
A management program for FIGO stage I-II nonserous, nonclear-cell adenocarcinomas was evaluated. Histopathology and DNA ploidy were used to estimate postoperatively the risk of progression or death of disease and to tailor treatment. The patient material was a population-based consecutive cohort of all women with endometrial cancer in the Southern Swedish Health Care Region diagnosed between June 1993 and June 1996 (n = 553). Of these, 335 were eligible for the management program. Patients estimated to be at low risk were treated by surgery only, while high-risk patients also received vaginal brachytherapy. A large low-risk group consisting of 84% (n = 283) of the patients with an estimated disease-specific 5-year survival of 96% (95% CI = 93-98%) was identified. The high-risk group (n = 52, 16%) showed a worse outcome with an 80% 5-year disease-specific survival (95% CI = 65-89%). The difference in survival between the groups was highly significant (P < 0.0001). Half of the progressions were distant in the high-risk group. Although there is a clear indication for adjuvant therapy for this group, locoregional radiotherapy could be expected to fail in cases with distant progression. Thus, effective systemic treatments need to be developed. Low-risk patients, constituting the majority (84%) of the patients, can be safely treated by surgery only.
