Clinical factors affecting endometrial receptiveness in oocyte donation cycles.
2008
Objective To provide a summary of the actual knowledge about the clinical factors affecting the oocyte recipient (other than those associated with uterine cavity abnormalities) on the outcome of oocyte donation cycles. Design Review of the literature. Setting Information regarding the association between age, body mass index (BMI), endometrial priming, tobacco consumption, hydrosalpinx, and endometriosis/adenomyosis in oocyte recipients and the results of oocyte donation cycles. Result(s) Recipient age and the presence of hydrosalpinx are clearly associated with a poorer outcome in oocyte donation cycles. The negative impact of tobacco consumption has recently been confirmed. The exact rele…
Is Hysteroscopy Better than Ultrasonography for Uterine Cavity Evaluation? An Evidence-Based and Patient-Oriented Approach
2016
Evaluation of the uterine cavity is an important part of the gynecological check, especially in symptomatic women and, over the last few decades, a number of technical and technological advancements has allowed a superb investigation of this organ. Traditionally, transvaginal ultrasound (TVUS) has been the first-line diagnostic tool for evaluating uterine diseases, also considering that gynecologists are familiar with the technique since it is included in the basic training in obstetrics and gynecology. Nevertheless, to date “office hysteroscopy” received growing attention since the development of smaller-diameter hysteroscopes which has made it possible to easily perform the hysteroscopy …
Isolated Dysphagia in a Patient with Medial Medullary Infarction – Effects of Evidence-Based Dysphagia Therapy: A Case Report
2021
Medial medullary infarction (MMI) is a vascular occlusion in the medulla oblongata leading to certain constellations of neurological symptoms and seriously affecting the patient. Effective evidence-based treatment of severe dysphagia as sole symptom of MMI has not yet been reported. This case study aims to report successful effects of evidence-based therapy based on findings of dysphagia symptoms and pathophysiology of swallowing by flexible endoscopic evaluation of swallowing (FEES) in severe isolated dysphagia after MMI. FEES was performed to evaluate swallowing pathophysiology and dysphagia symptoms in a 57-year-old male with severe dysphagia after MMI. On the basis of FEES findings, sim…
De Garengeot Hernia: Case Report and Review of the Literature of a Rare Femoral Hernia
2021
AbstractDe Garengeot hernia is a rare femoral hernia defined as the presence of the appendix within the femoral hernia sac. The incidence of appendicitis in this type of hernia is a rare condition that accounts for 0.08–0.13% of all De Garengeot hernias. We describe the case of a 61-year-old woman that presented at the emergency department with a tender mass (diameter 10 × 8 cm) in the right groin region for 5 days associated with pain in lower right abdomen and accompanied by fever (38 °C). Computed tomography (CT) of the abdomen revealed the presence of a complex fluid collection with small foci of air in the right inguinal region, measuring 9 × 7 × 10 cm in the 3 orthogonal dimensions an…
Seabream (Sparus aurata) long-term dominant-subordinate interplay affects phagocytosis by peritoneal cavity cells.
2012
Fish are sensitive to stressful conditions that affect their innate immune systems and increase their susceptibility to diseases. We examined the social stress of paired gilthead seabream (Sparus aurata). Social hierarchies (dominant/subordinate) were characterised by behavioural changes, such as “aggressiveness” and “feeding order”; hierarchical positions were established within an hour of exposure to social stress and remained unchanged for approximately 1 year. To characterise physiological stress, we measured blood plasma levels of cortisol, glucose, and lactate as well as osmolarity and observed that the levels of these stress markers were higher in subordinate individuals than in domi…
Differential expression of two glucocorticoid receptors in seabass (teleost fish) head kidney after exogeneous cortisol inoculation
2009
Stressful conditions include a prompt release of corticosteroid hormones which can mediate gene expression through glucocorticoid receptors (GR). Since two seabass (Dicentrarchus labrax) GRs have been cloned and sequenced from peritoneal cavity cells (DlGR1) and liver (DlGR2), a comparative amino acid sequence analysis that included Haplochromis burtoni HbGRs, was carried out and homologies disclosed. The DlGR1 and DlGR2 deduced aminoacid sequences showed 61% identity (I) and 70% similarity (S). Moreover, DlGR2 was similar to HbGR2b (69% I, 73% S), and the DlGR1 to HbGR1 (72% I, 78% S). In addition, we examined the expression of the DlGRs after exogeneous cortisol inoculation into the perit…
Oral leukoplakia: the ongoing discussion on definition and terminology
2015
In the past decades several definitions of oral leukoplakia have been proposed, the last one, being authorized by the World Health Organization (WHO), dating from 2005. In the present treatise an adjustment of that definition and the 1978 WHO definition is suggested, being : “A predominantly white patch or plaque that cannot be characterized clinically or pathologically as any other disorder; oral leukoplakia carries an increased risk of cancer development either in or close to the area of the leukoplakia or elsewhere in the oral cavity or the head-and-neck region”. Furthermore, the use of strict diagnostic criteria is recommended for predominantly white lesions for which a causative factor…
In vitro histological evaluation of the surgical margins made by different laser wavelengths in tongue tissues
2016
Background: Lasers have become standard tools for the surgical treatment of oral lesions. The purpose of this study is to determine the surgical margins and histologically evaluate the tissue thermal effects induced by different types of surgical instruments. Material and Methods: Cuts were made in pork tonguesâ mucosa with different lasers (Er:YAG at 2W with and without air / water spray and at 4W with and without air / water spray; CO2 at 3.5W and 7W in pulsed mode and at 7W in continuous mode; the diode laser at 3.5W and boost 3.5W in pulsed mode; Nd:YAG at 6W, 40Hz and electroscalpel at 5W and conventional scalpel as control. Macroscopic and microscopic morphological changes were evalua…
Learning from experience. Proposal of a refined definition and staging system for bisphosphonate-related osteonecrosis of the jaw (BRONJ)
2012
Dear Editor, It is the authors’ belief that the internationally accepted definition of bisphosphonate-related osteonecrosis of the jaws (BRONJ) (Ruggiero et al, 2009) has several limitations that prevent clinicians from being confident with the diagnosis of the disease. Following recognition of the non-exposed BRONJ clinical variant (Lazarovici et al, 2009), we all became aware that the presence of ‘exposed necrotic bone in the oral cavity’, as outlined in the American Association of Oral and Maxillofacial Surgery (AAOMS) case definition, is just one of the possible clinical manifestations of BRONJ and is not found in all BRONJ patients. As ‘bone exposure’ is certainly not the initial sign …
The deubiquitinating enzyme CYLD regulates the differentiation and maturation of thymic medullary epithelial cells.
2014
The cross talk between thymocytes and the thymic epithelium is critical for T-cell development and the establishment of central tolerance. Medullary thymic epithelial cells (mTECs) are located in the thymic medulla and mediate the elimination of self-reactive thymocytes, thereby preventing the onset of autoimmunity. Previous studies identified the deubiquitinating enzyme CYLD as a critical regulator of T-cell development by activating proximal T-cell receptor signaling during the transition of double-positive to single-positive thymocytes. Here we evaluated the impact of the naturally occurring short-splice variant of the cyld gene (sCYLD) on the development and maturation of mTECs. We foun…
