Complications Through the Use of Viscoelastics
2000
Viscoelastic material retained behind the IOL may cause a capsular bag distension in the early postoperative period. These eyes accumulate a transparent substance in the closed chamber inside the capsular bag from the IOL blocking the capsular opening. The capsular bag distension was first discribed by Davison in 1990. Miyake et al. proposed a new classification of capsular block syndrome and supposed viscoelastic material to cause early-postoperative capsular block syndrome (Miyake et al., 1999). Capsular bag distension after optic capture of a sulcus-fixated IOL was described by Basti et al. (1999).
Closed Incision Negative Pressure Therapy Achieves Better Outcome Than Standard Wound Care: Clinical Outcome and Cost-Effectiveness Analysis in Open …
2020
BackgroundSurgical site infections (SSIs) and surgical site occurrences (SSOs) are frequent post-operative complications that are dependent on the presence of different risk factors. The use of closed incision negative pressure therapy (ciNPT) is considered a measure by the WHO guidelines for prevention of SSIs. The prevention of SSOs is an extremely important issue in the ventral hernia repair (VHR) surgical field. SSO onset not only affects the patient's quality of life, but can also cause the onset of life-threatening conditions that may require re-hospitalization, re-intervention and often mesh removal. Such outcome can become extremely costly, contributing to increased health care cost…
Study of the interocclusal distortion in impressions taken with different types of closed-mouth trays and two types of impression materials
2010
The aim of this study was to compare different types of impression trays for the closed-mouth impression technique, using two different types of impression material. For this study, five different types of impression trays were used with two different types of impression materials, one of addition silicone and the other of polyether. We designed a model used for taking the impressions and for measuring interocclusal distortion. The results obtained show that the impression trays COE (GC (R) GC America INC. Alsip) and Premier (Premier (R), Premier Dental Products Co. Canada) show a lesser degree of interocclusal distortion when taking closed-mouth impressions. In terms of impression material…
Mathematical Modelling of Local Regulation of Blood Flow by Veno-Arterial Diffusion of Vasoactive Metabolites
1997
It is widely accepted that vasoactive substances which are consumed or produced by tissue metabolism play a role in the adjustment of local perfusion rate to the metabolic needs of the tissue. In order to evoke a response of the vascular system, these substances — in the following for simplicity denoted by “vasodilators” even though oxygen, for example, is a vasoconstrictor — need to get into close contact with the small arterioles which represent the most powerful effectors in perfusion control. On the other hand, tissue sites in which supply with nutrients is most critical (“lethal corners”) and in which a vasodilator signal may be generated earliest, are located hundreds of µm away from …
Cardiovascular disease in primary sjögren’s syndrome
2018
Background A close relationship between rheumatic diseases and cardiovascular disease (CVD) has been reported, accounting for the higher mortality and morbidity observed in these patients. In the last years, it has been clearly reported that patients affected by primary Sjogren's syndrome (pSS) experienced an increased risk of CVD. Objective This review aimed at investigating CVD, traditional cardiovascular (CV) risk factors and possible targeted therapeutic strategies in pSS patients. Method Available literature concerning CV risk factors in pSS patients has been selected and discussed. Conclusion Disease-related characteristics and traditional CV risk factors contribute to observed athero…
Walking in Natural Environments as Geriatrician’s Recommendation for Fall Prevention: Preliminary Outcomes from the “Passiata Day” Model
2020
Background: The Geriatric Unit of the University of Palermo developed the “Passiata Day” model, a green exercise intervention consisting of a one-hour walk, once/week, in a city park. The purpose of this study was to assess body balance in older people who walked regularly compared to sedentary people. Methods: 106 older people (75 women and 31 men; mean age: 72.3 ± 8.2 years) without fall history were invited to participate voluntarily in this natural environment walking program. After six months, both the participants who had taken part regularly in the walk (i.e., the physical activity group (PAG; n = 72; 54 women and 18 men; mean age: 70.7 ± 7.2 years)), and wh…
Postural Adaptations in Preadolescent Karate Athletes Due to a One Week Karate Training Camp
2013
Abstract The aim of this study was to investigate the effect of an increasing number of training hours of specific highintensity karate training on postural sway in preadolescent karate athletes. Seventy-four karatekas were randomly assigned to 1 of 2 groups: Karate Group (KG=37): age 10.29±1.68 yrs; or Control Group (CG= 37): age 10.06±1.77 yrs. The KG performed two sessions per day for 1 week in total, while the CG performed only 3 sessions during the same period. The center-of-pressure length (COPL) and velocity (COPV) were recorded under four different experimental conditions: open eyes (EO), closed eyes (EC), open eyes monopodalic left (EOL), open eyes monopodalic right (EOR), pre as w…
Magnesium and hypertension in old age
2021
Hypertension is a complex condition in which various actors and mechanisms combine, resulting in cardiovascular and cerebrovascular complications that today represent the most frequent causes of mortality, morbidity, disability, and health expenses worldwide. In the last decades, there has been an exceptional amount of experimental, epidemiological, and clinical studies confirming a close relationship between magnesium deficit and high blood pressure. Multiple mechanisms may help to explain the bulk of evidence supporting a protective effect of magnesium against hypertension and its complications. Hypertension increases sharply with advancing age, hence older persons are those most affected…
Dexamethasone in severe head injuries
1979
The results of a double-blind-study on the effects of placebo, a low dose and a high dose of dexamethasone on severe closed head injury are presented. 95 patients were selected and carefully analyzed according to mortality, neurological course and symptoms, midbrain lesions and final outcome. The results demonstrate that dexamethasone, particularly given in high doses, reduces mortality and improves the neurological course. The steroid treatment seems to improve chances as well as quality of survival. Apart from the dose, timing of administration is of great importance.
Emergent and delayed hybrid external fixation management of tibial pilon fractures: A multicentric retrospective analysis of 80 patients
2017
Objective: To report our experience with the hybrid external fixator in emergency. Methods: We assessed 80 cases of pilon fracture treated with the external fixator during the period of January 2009 and December 2016:55 men (69%) and 30 women (33%) with a mean age of 40 years (range between 16 and 70). About 45 occurred as isolated trauma, 35 instead were politrauma. Each patient underwent standard radiographic examination and a CT examination. There were 28 open fractures (35%), (Gustilo type 1, 2 and 3) while closed fractures showed soft tissue involvement of various grade (2-3 Tscherne classification). In all cases, the external fixation, sometimes associated with other reduction and syn…
