Frailty syndrome and pre-operative risk evaluation: A systematic review
2015
Abstract Background Frailty is a geriatric syndrome characterized by the clinical presentation of identifiable physical alterations and decreased physiological reserve. The assessment of frailty syndrome has been recently related with post-surgical outcomes and overall mortality in older individuals. Design and data sources We performed searches in Pubmed, Embase, Scopus, SCIELO and IME (Spanish medical index) databases from their start dates to February 2014 for original papers about the identification of the relationship between frailty and pre-operative risk evaluation in people aged 65 and over. Review methods We followed criteria of systematic PRISMA guidelines. Two independent reviewe…
Transoral laser microsurgery for glottic cancer in the elderly: Efficacy and safety
2018
Background Data about the results of transoral laser microsurgery (TLM) in elderly patients are limited. Methods A retrospective study of 72 consecutive cases of glottic carcinoma (63 pT1 and 9 pT2 cases) in elderly patients (≥70 years old, mean 76 years) treated with TLM was made. A systematic review of the literature was performed. Results Six patients (8%) had postoperative complications, but no treatment-related deaths were observed. Local recurrences occurred in 12 patients (16.5%): nine with pT1 (14%) and three with pT2 (33%) tumors. Five-year disease-specific survival (DSS), overall survival, and laryngectomy-free survival were 95%, 68%, and 88%, respectively. The literature review i…
Preserving the abductor mechanism in robotic THR: the influence of stem design and cutterpath.
2004
The tip of the greater trochanter is the attachment site for the abductor muscles of the hip joint. Its preservation in robotic and conventional THR is important for normal gait. The effect of different stem designs and robotic cutterpaths on the preservation of the trochanter tip is examined.One anatomical stem, one straight stem, and one stem specifically designed for robotic THR were implanted virtually in CT scans of osteoarthrotic hip joints using the Torch preoperative planning unit (URS-ortho). In transverse sections of the trochanter tip, dimensions of the trochanter area removed by the milling tool were recorded for each stem design and different cutterpaths (3-axis versus 5-axis m…
Mother-Child Teaching Strategies and Learning Disabilities
1994
The teaching strategies used by mothers of sons with learning disabilities (LD) (n = 30) and normally achieving sons (NLD) (n = 30) were examined. The children were matched for age (8- to 11-year-olds) and for parents' socioeconomic status. The behavior of mother-child pairs was videotaped in a teaching task that was constructed to resemble a homework assignment. The results showed that the mothers of children with LD used fewer high-level strategies, and their total time used in teaching was less than that of the mothers of NLD children. The mothers of children with LD exhibited more dominance and less emotionality and cooperation than did the mothers of NLD children; however, the mothers…
Postoperative laryngeal symptoms in a general surgery setting. Clinical study.
2013
INTRODUCTION: Vocal cord injuries (VI), postoperative hoarseness (PH), dysphonia (DN), dysphagia (DG) and sore throat (ST) are common complications after general anesthesia; there is actually a lack of consensus to support the proper timing for post-operative laryngoscopy that is reliable to support the diagnosis of laryngeal or vocal fold lesions after surgery and there are no valid studies about the entity of laryngeal trauma in oro-tracheal intubation. Aim of our study is to evaluate the statistical relation between anatomic, anesthesiological and surgical variables in the case of PH, DG or impaired voice register. MATERIALS AND METHODS: 50 patients (30 thyroidectomies, 8 videolaparoscop…
Urethrocutaneous fistula repair after hypospadias surgery
2003
To evaluate and compare the success rates of simple and layered repairs of urethrocutaneous fistulae after hypospadias repair.The charts of 72 children who developed fistulae after hypospadias repair were reviewed; 39 had a simple closure of the fistula, whereas 32 had a 'pants over vest' repair, in all cases after excluding an impairment of urine outflow.The success rate at the first attempt was 74% for simple closure and 94% for the layered repair; at the second attempt it was 80% and 100%, the difference being statistically significant for both repairs.Although probably far from an optimal technique for repairing urethrocutaneous fistulae, the pants-over-vest repair allows a good success…
Risks and relevance of preputial reconstruction in hypospadia repair.
2004
To assess the risks related to preputial reconstruction and its relevance for parents of children undergoing hypospadias repair.One-hundred-and-eighty-six children with distal hypospadias underwent circumcision or preputial reconstruction during the hypospadias repair. The type of procedure was chosen according to anatomical conditions and parents preferences after a careful explanation of possible related risks. Postoperative complications, outcomes, parents' satisfaction were assessed comparing circumcised and uncircumcised patients.No statistical differences in urethral complications were found between the two groups. Urethral or meatal strictures occurred in 11 (6.9%) cases after preput…
Behavioral and electrophysiological correlates of cognitive control in ex-obese adults
2017
Impaired cognitive control functions have been documented in obesity. It remains unclear whether these functions normalize after weight reduction. We compared ex-obese individuals, who successfully underwent substantial weight loss after bariatric surgery, to normal-weight participants on measures of resistance to interference, cognitive flexibility and response inhibition, obtained from the completion of two Stroop tasks, a Switching task and a Go/NoGo task, respectively. To elucidate the underlying brain mechanisms, event-related potentials (ERPs) in the latter two tasks were examined. As compared to controls, patients were more susceptible to the predominant but task-irrelevant stimulus …
Intraoperative monitoring of cerebral blood flow during ventricular shunting in hydrocephalic pediatric patients.
1995
Several studies have demonstrated lowered cerebral blood flow (CBF) in patients with hydrocephalus and symptoms of raised intracranial pressure. Ventricular shunting in such cases permits a sudden increase in CBF. The pathophysiology of functional brain deficit secondary to hydrocephalus is little understood. Improvement of the patient's clinical status after drainage of CSF suggests that cerebral dysfunction is not necessarily due to permanent brain damage. In fact, it improves rapidly after ventricular taps. In view of this it would be helpful to monitor cerebral perfusion. The transcranial Doppler (TCD) ultrasonography technique allows real-time monitoring of the intracranial circulation…
A New Method for Revision of Encapsulated Blebs after Trabeculectomy: Combination of Standard Bleb Needling with Transconjunctival Scleral Flap Sutur…
2016
Purpose A simple needling procedure is the standard method for restoring the function of an encapsulated bleb after trabeculectomy. However, postoperative hypotony represents a possible hazard. This study describes a new surgical approach for treating encapsulated blebs with reduced risk of early postoperative hypotony: bleb needling combined with transconjunctival sutures tightening the scleral flap directly. Methods The study included two groups of 23 patients with failing bleb following trabeculectomy: “Group 1” underwent simple needling revision of the filtering bleb and served as a control group, while “Group 2” received needling revision with additional transconjunctival scleral flap …
