UNLABELLED: We aimed to assess the prevalence of resistant hypertension (RH) in patients attending hypertension outpatient clinics and to identify risk factors for RH. We studied the medical records of the last visit of all patients (n = 1810; 40.4% males, age 56.5 ± 13.5 years) who attended at least once our hype…

Even though meteorologists have been aware of atmospheric blocking for more than 100 years, it is a phenomenon still not well forecast or completely understood. Also, while there is not one standard accepted definition, there are some commonalities known about the understanding of blocking behavior. Blocking occurs les…

Traumatic brain injury (TBI) is a common and significant public health problem all over the world. Until recently, TBI has been recognized as an uncommon cause of hypopituitarism. The studies conducted during the last 15 years revealed that TBI is a serious cause of hypopituitarism. Although the underlying pathophysiol…

Interactions between fishes and the benthos have shaped the development of marine ecosystems since at least the early Mesozoic. Here, using the morphology of fish teeth as an indicator of feeding abilities, we quantify changes over the last 240 million years of reef fish evolution. Fossil and extant coral reef fish ass…

PURPOSE OF REVIEW: Endoscopic therapies for gastroesophageal reflux disease represent a minimally invasive alternative to medical or surgical treatment. These devices include suturing, radiofrequency energy, and bulking agent technologies. Research into the use of these technologies in gastroesophageal reflux disease c…

BACKGROUND: Endobronchial lung volume reduction (EBVR) with one-way valves introduced into the most diseased lobe of the lung is a non-invasive method to improve lung function in patients with severe heterogenous emphysema. The problem is to select the right patients for the procedure. Furthermore, the long-term effect…

The present study was conducted to investigate the trends of vaginal hysterectomy for genital prolapse in last 20 years by analyzing case records of affected women. During the analysis period, 4831 women underwent hysterectomy; records of 4223 (87.5%) were available. Of these, 911 (21.6%), 2.7% of 34,080 gynecological…

Nearly two thirds of the cancers which will appear in the next 25 years will occur due to unawareness of the public. In a population genetic study in Alexandria, Egypt, we found that the parents of 20% of the population are first degree cousins. Out of 9,587 female cancer cases registered in the last 10 years by the Al…

We report three cases of patients with liposarcomas of the abdomen who had been treated during the last 13 years (1980-1993). Two patients were men, aged 29 and 51 years, with tumors of the retroperitoneal space and the third patient was a woman aged 64 years with a tumor in the peritoneal cavity. Therapeutic treatment…

BACKGROUND: The burden associated with the treatment of patients with multiple myeloma (MM) is expected to increase due to the aging population. Thus, policymakers and clinicians need a holistic view of the healthcare resource use (HCRU) and costs associated with MM and its treatment for informed decision making. Howev…

Approximately 80% of a self-selected sample of 593 heterosexual undergraduate college students studied at a large Midwestern state university in 1988 had ever experienced penile-vaginal or penile-anal intercourse. One-fifth of the 477 sexually experienced women and men said they had had heterosexual and intercourse. Th…

A survey was carried out to evaluate the knowledge, attitudes and practice of female prostitutes In Phnom Penh (Cambodia) in 2000 and 2004. A total of 131 women were included both years. The population was 75% Cambodian and 25% Vietnamese. Average age was 22.9 years in 2000 and 25.5 years in 2004. Sixty-seven percent o…

The authors present their experience with surgical treatment of achalasia of the oesophagus in child age. During a nine-year period (1984-1992) they operated 11 children with achalasia. The group comprised 6 boys and 5 girls. The mean age at the time of operation was 9.5 years. The youngest patient was operated at the…

An analysis is presented of 35 cases of chorea as a symptom of polycythaemia. This analysis reveals: (a) whereas polycythaemia occurs predominantly in males (3:2), polycythaemic chorea (PC) occurs predominantly in females (5:2), at a real ratio of female:male = 4:1, the prevalence being 1-2.5% of polycythaemic patients…

A series of 37 patients with cecal volvulus treated at three different Swedish hospitals during the years 1952-1973 is presented. The symptoms, physical findings and radiologic features are presented. The associated factors found at operation are described and their possible role in provoking torsion is discussed. In 5…

The complete classification of (primitive, generic) parallelohedra in a given dimension is a challenging computational task. Nearly 50 years have passed since the classification for the last dimension, n = 5, was completed. One application of such a classification is in solving the lattice sphere covering problem for t…

In the last years, great progress has been accomplished in the development of aptamer sensors with different transducers. In order to improve the sensitivity of these biosensors, several methodologies have been employed. In this Special Issue, the state of art and the future trends in the field of aptamer sensors have…

The cat's mesencephalic raphe, caudally extended to the locus ceruleus and rostrally to the habenulo-interpedunculary area, was reconstructed with foamy-plastic plates in a stereotaxis ensemble of the brainstem. This reconstruction serves as an important reference to the topography and for interpreting the functional b…

BACKGROUND: For children requiring weight-based resuscitative measures, it is often difficult to obtain an accurate weight. In these cases, it is common practice to estimate the weight based on age. As the average weight of Australian children has increased over the last two decades, the widely used advanced paediatric…
