(b) During the 1980s and 1990s the significance of socia…

Background. One of the most important elements of a properly performed arthroscopy, apart from the surgeon's experience is an appropriate type of anesthesia chosen by the anesthesiologist. The type of anesthesia depends on many factors, for example the patient's general condition, the type and extent of the knee injury…

During the last few years there has been a rapid increase in the use of electrochemical reactions in lab-on-a-chip devices. This development, which has so far mainly focussed on electrochemical detection in chip-based capillary electrophoresis, can be explained by the fact that electrochemical techniques and devices ar…

The human Y chromosome is running out of time. In the last 300 million years, it has lost 1393 of its original 1438 genes, and at this rate it will lose the last 45 in a mere 10 million years. But there has been a proposal that perhaps rescue is at hand in the form of recently discovered gene conversion within palindro…

Since the postulation of an "antiproliferative factor" in 1998 and a description, six years later, of this putative central protein in the etiologic pathway of the painful bladder syndrome/interstitial cystitis, there have been no dramatic breakthroughs in the field. Although much potentially exciting work is in progre…

Background. In patients older than 65 with osteoporosis, fractures of the proximal end of the humeral bone pose a difficult clinical problem. There is a larger body of opinion, however, favoring conservative treatment, while surgical intervention is most often reserved for complicated fractures.<br /> Material and meth…

This article suggests that there is a high probability of connections between emotional and physical health in animals. Many avian veterinarians are putting these ideas into practice. Recently, several veterinary schools have invited speakers to address their students about these ideas, suggesting a positive change in…

Data are presented showing phage types and antibiotic-resistant patterns of Staphylococcus aureus over the last 20 years. The spontaneous emergence of different phage types associated with increases and decreases in antibiotic resistance has been shown to be cyclic in nature with prevalence for 5 to 8 years, followed b…

Hydatid disease is endemic in several Mediterranean countries, posing an important health problem for these countries. The hydatid cyst is characterized by cystic lesions with clear boundaries, which can be observed in all parts of the body. Approximately 70 % of hydatid cysts are situated in the liver, followed by the…

During the last 5 years, Ecuador has published a series of progressive laws aiming to protect girls and women against any type of violence. While these efforts are of extreme importance, concerns were raised by national nongovernmental organizations that the official numbers might be biased due to the restricted defini…

BACKGROUND/PURPOSE: To evaluate long-term visual outcomes of Boston type I keratoprosthesis (KPro) surgery and identify risk factors for visual failure. METHODS: Single surgeon retrospective cohort study including 85 eyes of 74 patients who underwent KPro implantation to treat severe ocular surface disease, including…

In the last fifty years, there has been a great improvement in social and health conditions. This have led to a significant increase in human lifespan as never seen before. In Italy, older persons are the fastest growing sector of society, mainly due to scientific progress but also to a decrease in the natality rate. A…

INTRODUCTION: In a retrospective study a treatment concept for Perthes' disease dependent on the containment was applied. PATIENTS/METHODS: 49 hips of 41 children (9 female, 32 male) were treated between 01. 01. 1990 and 31. 12. 1995. In our concept of treatment a varus femoral osteotomy was performed in 28 cases with…

OBJECTIVE: To evaluate the curative effect of short-segment transpedicular fixation plus vertebra fracture fixation for thoracolumbar burst fractures in patients with osteoporosis. METHODS: The clinical data of thoracolumbar burst fractures in 46 patients with osteoporosis, single segment fracture and neurological int…

INTRODUCTION: In the last few years, use of psychotherapy has been studied in both our country and other parts of the world. The aim of our study was to determine the current prevalence of psychotherapy use, its characteristics and to compare it with the study done in 2007. METHOD: A survey was conducted among 1348 in…

BACKGROUND: Recent studies suggest that colonoscopies done in the morning have better-quality bowel preparations than those done in the afternoon. OBJECTIVE: We aimed to determine how the duration of the interval between the end of the preparation and the start of the colonoscopy affects preparation quality. DESIGN:…

The ability to return to work after treatment of diseases is an important issue. Aim of this study is to compare surgery and conservative management focusing on clinical outcome and ability to return to work in patients with intramedullary spinal cord ependymoma. Retrospective, single center study. The neurological sta…

BACKGROUND: Pulmonary hypertension (PH) may limit the outcome of pediatric heart transplantation (pHTx). We evaluated pulmonary hemodynamics in children undergoing pHTx. METHODS: Cross-sectional, single-center, observational study analyzing pulmonary hemodynamics in children undergoing pHTx. RESULTS: Twenty-three chi…

The characteristic pattern of fusion of distal tibial epiphysis explains the special configuration of the fragments in the triplane fracture and the "juvenile" fracture of Tillaux in adolescents. The application of external rotation force produces Tillaux and triplane fractures of the lateral portion of the distal tibi…

BACKGROUND: Posttraumatic arthritis secondary to lateral tibial plateau fracture malunion causes pain and limited function for patients. It is sometimes technically challenging to correct malalignment in these patients with advanced arthritis using osteotomies. Lateral unicompartmental knee arthroplasty (UKA) may be an…
