BACKGROUND: To evaluate cancer incidence among licenced commercial pilots in association with cosmic radiation. METHODS: Cohort study where ionizing radiation dose of cosmic radiation was estimated from airline data and software program and cancer incidence was obtained by record linkage with nation-wide cancer registry. All licenced commercial male airline pilots were followed from 1955 to 2015, ever or never employed at airline with international routes. Standardized incidence ratios were calculated and relative risk by Poisson regression, to examine exposure-response relation...

Death was the most important side effect of anaesthesia in dentistry. In this article we reviewed more than 20 studies with adequate data focusing on death associated with dental procedures since 1955 and found 218 deaths out of 71,435,282 patients (3 deaths per 1,000,000 persons) with the mortality rate of 1:327,684. In addition, mortality rate per million has dropped to half (6.2 per 1,000,000 vs. 3 per 1,000,000) since 1955 till the last report in 2012 without any sex predilection. In children, most cases died in the age of two to five years...

EDITORIAL
Richard D deShazo, Sara B Parker
During the fight to end segregation in the United States, most of the 25 or so black physicians who had not already left Mississippi took risks to become active in civil rights locally and nationally. One of the first was T.R.M. Howard, MD, whose life story is both an encouragement and warning for today's physicians. Howard, the protégé of a white Adventist physician, became active in civil rights during medical school. While serving as chief surgeon of the all-black hospital in Mississippi, he formed his own civil rights organization in 1951 and worked to solve the shootings of 2 of its members, George Lee and Gus Courts, and the murder of Emmett Till in 1955...

The early techniques of cleft lip repair involved the straight-line technique, the triangular flap technique or some kind of geometric line (triangular, quadrangular closure). A turning point in cleft lip surgery was in 1955 when doctor. Millard presented his method: the rotation-advancement technique or flap, at the First International Congress of Plastic Surgery in Stockholm. Today, the technique, with or without some modifications, is used by more than 85% of cleft surgeons around the world. We are presenting a patient with complete unilateral cleft lip and palate who underwent surgery sixty-five years ago...

Adhesive dentistry has undergone great progress in the last decades. In light of minimal-invasive dentistry, this new approach promotes a more conservative cavity design, which relies on the effectiveness of current enamel-dentine adhesives. Adhesive dentistry began in 1955 by Buonocore on the benefits of acid etching. With changing technologies, dental adhesives have evolved from no-etch to total-etch (4(th) and 5(th) generation) to self-etch (6(th), 7(th) and 8(th) generation) systems. Currently, bonding to dental substrates is based on three different strategies: 1) etch-and-rinse, 2) self-etch and 3) resin-modified glass-ionomer approach as possessing the unique properties of self-adherence to the tooth tissue...

BACKGROUND: Schwannomas (or neurilemmomas) of the tongue are benign, usually solitary, encapsulated masses derived from Schwann cells. Clinical evidence indicates that schwannoma is painless and slow growing. In general, schwannoma is treated by surgical excision. Here, we describe a case of schwannoma of the tongue, include a review of the literature from 1955 to 2016, and provide data on age, gender, location, presenting symptoms, size, and treatment methods. CASE PRESENTATION: A 71-year-old female patient presented with a swelling at the base of the tongue of unknown duration...

BACKGROUND: More patient-specific medical care is expected as more is learned about variations in patient responses to medical treatments. Analytical tools enable insights by linking treatment responses from different types of studies, such as randomized controlled trials (RCTs) and observational studies. Given the importance of evidence from both types of studies, our goal was to integrate these types of data into a single predictive platform to help predict response to pregabalin in individual patients with painful diabetic peripheral neuropathy (pDPN)...

In a karst pit above City of Rijeka in Croatia the hazardous industrial waste was continuously disposed from 1955 to 1990, and later it was periodically used as an illegal dump site. The surface part of a technosol at the edge of dump was analysed mineralogically, geochemically and bacteriologically. From the technosol rich in petroleum hydrocarbons and heavy metals three isolates of Acinetobacter baumannii were recovered. Isolates from technosol shared many features that are previously described for clinically isolates: the affiliation to IC1 and 2, multi-drug resistant (MDR) or extensively drug-resistant (XDR) antibiotic resistance profile, carbapenem resistance mediated by blaOXA72 and blaOXA23 genes, and the expression of virulence factors...

During the second half of the 20th century farming systems in hilly and mountainous areas of Mediterranean Europe were progressively abandoned and the forest cover subsequently re-expanded. This paper investigates the environmental impacts of land-use/land-cover (LULC) changes on hydrological ecosystem functions (HEFs) in the Upper Alento River Catchment (UARC) in southern Italy. We document the human-driven post-war landscape in 1955 with its maximum expansion of pasture and crops. By 1998 forest cover had doubled and cropland had roughly halved due to decades of land abandonment and reduction in human pressure...

Data regarding clinical characteristics, therapy, maternal and fetal outcomes of pregnancy-associated acute myeloid leukemia (PA-AML) are limited. This study (including 138 cases published between 1955 and 2013) provides comprehensive assessment of these clinical parameters and may serve as a platform for developing management recommendations. Most patients (58%) received anthracycline-cytarabine-based regimens (ACBRs), which were associated with significantly increased complete remission (CR: 91%). Yet, the maternal overall survival (OS: ∼30%) was relatively low, probably reflecting reduced application of risk-adapted consolidation and allogeneic stem cell transplantation (allo-SCT)...

Extensive LSD testing was conducted by the US Army at Edgewood Arsenal and other locations from 1955 to 1967. A number of different reports have been produced describing the health effects of this testing, including the Veterans Health Initiative Report in 2003. By and large, these reports gloss over and minimize the short and long-term side effects and complications of this testing. However, the reports themselves document frequent, severe complications of the LSD. These side effects were regarded by the Army as having been directly caused by the LSD exposure...

Intracellular organelles, including secretory vesicles, emerged when eukaryotic cells evolved some 3 billion years ago. The primordial organelles that evolved in Archaea were similar to endolysosomes, which developed, arguably, for specific metabolic tasks, including uptake, metabolic processing, storage and disposal of molecules. In comparison with prokaryotes, cell volume of eukaryotes increased by several orders of magnitude and vesicle traffic emerged to allow for communication between distant intracellular locations...
