Forty-six consecutive polyethylene cups used in cemented first-time revision of the acetabulum were evaluated at repeated occasions up to mean 10.7 years (range, 0.5-16.3 years). At the last follow-up, 3 cups had been revised (6.5%), 2 because of loosening and 1 because of fracture of the acetabulum. Furthermore, 4 wer…

Vitamin A deficiency (VAD) affects 12% of Peruvians under 5 years of age. Recent studies have shown an association with hematopoiesis and iron metabolism. In Peru, 3-quarters of a million children have anemia. We aimed to identify an association between Vitamin A supplementation (VAS) and anemia in children unde…

The New Jersey horse racing industry has declined over the last 5 years as indicated by decreases in the number of racing days, stallions standing, mares bred, and foals registered. These changes were hypothesized to have potential negative consequences for veterinary practices. The objective of the survey was to inves…

Conventional acoustic hearing aids are limited in their performance. Due to physical laws their amplification of sound is limited to within 5 kHz. However, the frequencies between 5 and 10 kHz are essential for understanding consonants. Words can only be understood correctly if their consonants can be understood. Furth…

OBJECTIVE: The aim of this study was to analyze hearing results of stapes surgery in otosclerotic patients older than 65 years. STUDY DESIGN: Among 473 primary stapedectomies, 16 were performed in patients over 65 years old and were retrospectively reviewed. Hearing results were compared with those of a randomly selec…

Iron deficiency anemia is nowadays the world most prevalent nutritional problem. Several studies concerning anemia prevalence were carried out in Brazil with pregnant women and children aged less than 5 years, restricted mainly to northeast and southeast regions of the country. More recently, groups other than those of…

Eleven children with acute inflammatory polyneuropathy were treated with a short course of intensive plasmapheresis. The 5 males and 6 females ranged in aged from 19 months to 16 years (mean: 7.8 years). The interval from disease onset to the initiation of plasmapheresis therapy was less than 7 days in 5 patients and l…

The glutaraldehyde-preserved stented porcine xenograft valve has been durable in adult patients with a low incidence of valve-related complications. In children, however, early degeneration and calcification of this valve is now being reported. The etiology of the early degeneration is still unclear but may be related…

Two hundred twenty-seven patients (median age 5.4 months) in whom a Waterston anastomosis was done for initial palliation of tetralogy of Fallot between 1966 and 1979 were studied. Twelve patients died in the hospital (5.3%; 70% confidence limits, 3.8% to 7.3%). Young age, low weight, and poor clinical condition did no…

Comparative investigations of 440 urinary bladder biopsies from 1927 to 1957 and 1634 bladder biopsies from 1972 to 1976 showed the following: Epithelial bladder tumors are today found much more frequently among old age groups than they used to be. Bladder carcinoma have also been noticed more frequently among women in…

Reports of successful attempts at resuscitation have been published for more than 200 years, but systematic analysis of an optimal technique has been undertaken for only the last 20 years. As a result of these experiments and of the many years of experience of resuscitation teams, extensive recommendations were formula…

The management of spinal deformities diagnosed before the age of 10 is critical due to the child's development, skeletal system, and growth mechanism. Magnetically controlled growing rods (MCGRs) are a surgical treatment option for the growing spine. The aim of this study was to analyze the radiological findings of pat…

The timing of the placental mammal radiation has been a source of contention for decades. The fossil record of mammals extends over 200 million years, but no confirmed placental mammal fossils are known prior to 64 million years ago, which is approximately 1.5 million years after the Cretaceous-Paleogene (K-Pg) mass ex…

This study assessed genetic and environmental contributions to temperament during adolescence within the Nonshared Environment and Adolescent Development project (NEAD; D. Reiss, J. M. Neiderhiser, E. M. Hetherington, & R. Plomin, 2000). NEAD is a national study that includes twins and other sibling types who vary in r…

Human fossils dated between 3.5 and nearly 7 million years old discovered during the last 8 years have been assigned to as many as four new genera of the family Hominidae: Ardipithecus, Orrorin, Kenyanthropus, and Sahelanthropus. These specimens are described as having morphological traits that justify placing them in…

BACKGROUND: Since May 1992 we have used video-assisted thoracic surgery (VATS) for the treatment of the spontaneous pneumothorax. In this study we review the results obtained with this technique and we compare them with those obtained by conventional surgery (1976-1992). METHODS: 110 patients (98 males and 12 females,…

PURPOSE: Analysis of etiological factors and functional assessment of the eyes. MATERIAL AND METHODS: Optic disc hypoplasia was diagnosed in 43 children, aged 12 months--12 years, unilateral in 9 (20.9%). The follow-up ranged from 8 months to 9 years, the mean age of patients during the last examination was 10.4 years…

The authors present 34 medulloblastoma/primitive neuroectodermal tumours of the posterior fossa in children operated during the last ten years (1979-1989). Total removal of tumours has been performed in 13, and maximal-subtotal resection in 19 patients. Only four tumours were classified as small (group T1-T2). Partial…

The incidence of tuberculosis (TB) among Israeli-born children was studied. The incidence rates for Jews and non-Jews were compared at various ages and in different years. Non-Jews had higher rates of TB than had Jews at all ages. The difference between the two groups was largest at age 5 to 9 years (rate ratio, non-Je…

The case history of seven children aged 1 5/12 to 5 9/12 years with non tuberculous bacterial pericarditis, observed in the last 8 years at the University children's hospitals of Basle, Berne and Zurich is reported. The history showed febrile illness of 3--14 days duration, which led to an admission diagnosis of pneumo…
