BACKGROUND: The lack of instrumental data before the mid-19th-century limits our understanding of present warming trends. In the absence of direct measurements, we used proxies that are natural or historical archives recording past climatic changes. A gridded reconstruction of spring-summer temperature was produced for…

BACKGROUND: Benign bone tumors are common incidental findings in the pediatric population during radiographic evaluation. Counseling these patients requires reassurance and raises questions about the natural history of these tumors over time. The purpose of this study was to estimate the prevalence and observe the beha…

Omalizumab is frequently used as add-on treatment to inhaled corticosteroids (ICS) and long-acting β2-agonists in patients with suboptimal control of severe asthma. Patients with severe asthma will typically require chronic treatment, although due to the limited amount of data available there are still some conce…

BACKGROUND: The lifetime risk of pancreatic cancer in women with a germline mutation in BRCA1 and BRCA2 is not well established. In an international prospective cohort of female carriers of BRCA1 and BRCA2 mutations, the cumulative incidence of pancreatic cancer from age 40 until 80 years was estimated. METHODS: A tot…

BACKGROUND: Sacrectomy may offer curative potential for primary sarcomas of the sacrum. However, it is unclear whether and to what extent sacrectomies achieve local control. QUESTIONS/PURPOSE: We therefore determined the curative potential, walking ability, continence control, and quality of life for children after sa…

Inappropriate left ventricular mass (LVM; ie, the value of LVM exceeding individual needs to compensate hemodynamic load) predicts the risk of cardiovascular (CV) events, independent of risk factors, either in the presence or in the absence of traditionally defined LV hypertrophy. The relation between changes in approp…

A new device was designed based on the Ilizarov principle. The design is a new configuration of the external components. The 0.9-mm pins are similar to those used in bone fixation during the last 15 years, are bicortical, and utilize hand torque for insertion.

Neuropathology has been originated in clinical necessity and trended progressively towards independence in the last 30 years all over the world. In the future, substance and methods in neuropathology demand a good correlation to clinical and theoretical branches of medicine and a solid integration in the manner to work…

Significant advances in perinatology and neonatology in the last decade have resulted in increased survival of extremely premature infants. Survival rates for infants born in tertiary perinatal and neonatal care centers in the United States in the 1990s increase with each week of gestational age from 22 through 26 week…

PURPOSE: In this prospective multicenter study, we evaluate the effectiveness of corticosteroid plus vertebroplasty rather than vertebroplasty alone in the analgesic treatment of single-level vertebral neoplasms or pathological fractures. MATERIALS AND METHODS: From January 2009 to February 2011, we prospectively enro…

The authors present results of 32 operations with capsular tension ring performed in eyes with zonular dehiscence. There were 14 women (50%) and 14 men (50%), altogether 28 patients (32 eyes). Mean patient age was 47.1 years (range 22-89 years). The reason for zonular weakness was trauma in 15 eyes (46.9%), Marfan's sy…

We studied the epidemiology of myasthenia gravis (MG) in western Denmark from 1975 to 1989, basing case identification on records from all hospitals in the survey area. The population surveyed was 2.80 million in 1985. The average annual incidence rate was 5.0 per million population (women, 5.9; men, 4.2). The point-pr…

In order to test whether the mean age at cataract surgery has changed over the course of the last 30 years, a hospital series of 5443 patients undergoing cataract extraction between 1956 and 1987 is reviewed. All cases attended the same University Eye Clinic of Milan and most were resident in the same geographical area…
