Syncope without prodromes is associated with excessive plasma release of adenosine at the time of syncope during head-up tilt table test.

Background: In syncopal patients without underlying structural disease, we sought to investigate the association of Adenosine Plasma Levels (ADP) with the clinical presentation of neurally mediated syncope (NMS) and the outcomes of Head-Up Tilt Table Test (HUTT) and Adenosine test (ADT).

Methods: We studied 124 patients with different clinical types of NMS, i.e.

Comparison of the Weil and Triple Weil Osteotomies: A Clinical Retrospective Study.

Introduction: The Weil and triple Weil osteotomies are two widely used procedures in the surgical treatment of metatarsalgia. The aim of this comparative retrospective study was to evaluate the functional results and determine the complications of the two types of osteotomies in a series of patients who underwent surgery due to third rocker metatarsalgia.

Material And Methods: In this paper, 71 patients were included between September 2015 and October 2020.

Biomechanical Analysis of the Change of the Metatarsophalangeal Joint's Center of Rotation After Weil and Triple Weil Osteotomies: A Comparative Cadaveric Study.

Background The aim of the present biomechanical study on cadavers was to determine both the center of rotation of the metatarsophalangeal joints and the position of the tendons of the interosseous muscles after the Weil and triple Weil osteotomies, and to compare these parameters in order to clarify the pathogenesis of dorsal stiffness and floating toe. Materials and methods Seven fresh-frozen cadaveric feet were utilized. After completing the preparation of both the plantar and the dorsal surface, we performed the dissection of the entire second, third and fourth rays, and each ray was fixed to a wooden wall mounted on a movable frame.

Aggressive angiomyxoma to 57-year old man.

Aggressive angiomyxoma is a rare mesenchymal tumor occurring usually in women of reproductive age in pelvic-perineum region. These myofibroblastic tumors rarely affect men and non-pelvic-perineum anatomical sites. There are few literature references for aggressive angiomyxoma in men.

The role of negative pressure wound therapy in salvaging a six-year-old child's crushed foot - A case report.

Unlabelled: Crushed extremity is an infrequent injury in children and represents a major challenge for the orthopaedic surgeon. Sometimes the decision making process, whether to amputate or save a limb, is very difficult. Several scoring systems have been developed in order to determine the fate of crushed extremities, but they are not always predictive when patients are children.

Deficient Phagocytosis Among HIV-1 Infected Adults Over Time Even in HAART Setting.

Background: Phagocytosis is regarded to be impaired in HIV-1 infected adults, leading to high frequency and severity of several infections in this population. Data is contradictory with regards to individual facets in HIV infection.

Objective: Aim of this study was to assess the phagocytic activity during the natural course of HIV infection.

Antiretroviral naive and treated patients: Discrepancies of B cell subsets during the natural course of human immunodeficiency virus type 1 infection.

Aim: To evaluate alterations of memory B cell subpopulations during a 48-wk period in human immunodeficiency virus type 1 (HIV-1) patients.

Methods: Forty-one antiretroviral naïve and 41 treated HIV-1 patients matched for age and duration of HIV infection were recruited. All clinical, epidemiological and laboratory data were recorded or measured.

Could Somatostatin Enhance the Outcomes of Chemotherapeutic Treatment in SCLC?

Purpose: Somatostatin is a peptide with a potent and broad antisecretory action, which makes it an invaluable drug target for the pharmacological management of pituitary adenomas and neuroendocrine tumors. Furthermore, somatostatin (SST) receptors (SSTR1, 2A and B, 3, 4 and 5) belong to the G protein coupled receptor family and are overexpressed in tumors. Since, human small-cell lung cancer overexpresses somatostatin receptors (STTR), they could be legitimate targets for treating SCLC.

Stimulation of natural killer cells by homoeopathic complexes: an in vitro and in vivo pilot study in advanced cancer patients.

The present study was designed in order to evaluate the effects of five homoeopathic complex preparations on functional activity natural killer cells (NKCs) in advanced cancer patients. We examined the effects of Coenzyme Compositum®, Ubichinon Compositum®, Glyoxal Compositum®, Katalysatoren® and Traumeel® on the functional activity of NKCs. Experimental procedures included in vitro and in vivo trials.

Is polyploidy a persevering accident or an adaptive evolutionary pattern? The case of the brine shrimp Artemia.

Asexual organisms are confronted with substantial drawbacks, both immediate and delayed, threatening their evolutionary persistence. Yet, genetic associations with asexuality may refresh the gene pool promoting adaptation of clonal lineages; polyploidy is one of them. Parthenogenesis itself and/or polyploidy are responsible for the maintenance and spread of clones in Artemia, a sexual-asexual genus of halophilic anostracans.
