Objectives: Each case of a continuous series of invasive cervical cancer cases was studied with a structured review procedure conducted by an expert panel to assess the reason that it was not detected before it became invasive., Methods: All cases of invasive cervical cancer diagnosed in a 5-year period among Connecticut residents were identified; a screening history and screening outcome were obtained for 72% (481 of 664)., Results: Two hundred fifty women (51.9%) had suboptimal screening. One hundred thirty-seven women (28.5%) had never had a screening test, and their mean age was greater than that of the rest of the study population (64.5 years vs 46.5 years). Of the 344 women who had ever had a Pap test, 113 (32.8%) had their last Pap test 5 or more years before their diagnosis of invasive cancer; 52 (15.1%) were not followed up properly; 33 (9.6%) had their last smear misread as normal; and 118 (34.3%) developed cervical cancer within 3 years of their last Pap test., Conclusions: Physicians, nurses, and other care providers need to ensure that woman have timely and accurate screening with proper follow-up, make increased efforts to reach older women, and improve quality control of Pap smear readings.

This study describes the epidemiology of sudden infant death syndrome (SIDS) among infants born during 1974 to upstate New York residents. Birth certificate characteristics for 184 SIDS cases are compared with those of 417 infants dying from other causes in the same age range, 7-365 days. The results confirm the following as infant risk factors: fall or winter birth, low birthweight for gestational age, twin birth, and live birth order three or more. Maternal risk factors include: age under 20, abnormal uterine bleeding during pregnancy, late initiation of prenatal care, less than 12 years of education and single marital status. The increased risk for mothers who first gave birth in their teens and for second-born twins has not been previously reported. The evidence that SIDS babies are small for gestational age, that twins, especially the second born, and babies whose mothers experienced abnormal uterine bleeding during pregnancy are all at increased risk of SIDS suggests that perinatal stress leading to hypoxia is one of the components that determine the risk of SIDS.
