Comparison of Ondansetron versus Clonidine efficacy for prevention of postoperative pain, nausea and vomiting after orthognathic surgeries : a triple…
2018
Background The aim of this randomized controlled triple blind trial was to compare the efficacy of clonidine with dexamethasone versus ondansetron with dexamethasone for postoperative pain, nausea and vomiting prevention in orthognathic surgery patients. Material and Methods In this clinical trial study, 30 consecutive patients with skeletal class III deformities were candidates for orthognathic surgery in Qaem hospital, Mashhad University of medical sciences, Mashhad, Iran from March to November 2017. These subjects were randomly assigned to two equal number groups, ondansetron or clonidine. Patients received either oral ondansetron 8mg or oral clonidine 150μg as premedication, 1 hour befo…
Costochondral graft with green-stick fracture used in reconstruction of the mandibular condyle : experience in 13 clinical cases
2008
Since its publication in 1920 by Gillies, costochondral grafts have been used by surgeons to replace an injured mandibular condyle and to reconstruct the temporomandibular joint. This procedure is currently applied in cases of congenital dysplasia, developmental defects, temporomandibular ankylosis, neoplastic disease, osteoarthritis and post-traumatic dysfunction. Over the years, various procedures for the reconstruction with this type of graft have been described. In 1989, Mosby and Hiatt described a technique for setting the graft securely, reducing the space between the graft and the mandibular area. In 1998, Monje and Martín-Granizo developed a variation of this method, enabling a prec…
Pain and swelling after periapical surgery related to oral hygiene and smoking.
2007
Objectives To evaluate pain and swelling during the first week after periapical surgery and its relation to patient age, gender, oral hygiene, and smoking. Study design One hundred two patients (31 men and 71 women) with a mean age of 40.2 years underwent periapical surgery. Age, gender, and oral hygiene and cigarette smoking before and during the postoperative course were noted. Pain and swelling scores were recorded on a descriptive 4-point scale at 2, 6, and 12 hours after surgery, and each day thereafter for 1 week. The data were statistically evaluated for significant differences. Results The highest intensity of pain occurred during the first 48 hours, and swelling peaked on the secon…
Increased age-associated mortality risk in HLA-mismatched hematopoietic stem cell transplantation.
2016
We investigated a possible interaction between age-associated risk and HLA-mismatch associated risk on prognosis in different age categories of recipients of unrelated hematopoietic stem cell transplants (HSCT) (n=3019). Patients over 55 years of age transplanted with 8/10 donors showed a mortality risk of 2.27 (CI 1.70–3.03, P<0.001) and 3.48 (CI 2.49–4.86, P<0.001) when compared to 10/10 matched patients in the same age group and to 10/10 matched patients aged 18–35 years, respectively. Compared to 10/10 matched transplantations within each age category, the Hazards Ratio for 8/10 matched transplantation was 1.14, 1.40 and 2.27 in patients aged 18–35 years, 36–55 and above 55 years. Model…
Risk factors for recurrence and incontinence after anal fistula surgery
2009
Objective: Fistula-in-ano continues to raise problems that require important therapeutic decisions. Our aim was to evaluate its recurrence and incontinence risk factors. Method: We analysed a series of 279 patients who had undergone anal fistula surgery with long-term follow-up. Results: 42.7% of the fistulae were considered complex and 46% had been referred from other institutions. There was delayed healing or recurrence in 7.2% patients, which appeared at a median of 4 months. The factors associated with recurrence were the type of fistula (extrasphincteric/suprasphincteric), nonidentification of internal opening (IO), recurrent or complex fistulae (CF), and associated chronic abscess. On…
Biomechanical implications of excessive endograft protrusion into the aortic arch after thoracic endovascular repair
2015
Endografts placed in the aorta for thoracic endovascular aortic repair (TEVAR) may determine malappositioning to the lesser curvature of the aortic wall, thus resulting in a devastating complication known as endograft collapse. This premature device failure commonly occurs in young individuals after TEVAR for traumatic aortic injuries as a result of applications outside the physical conditions for which the endograft was designed. In this study, an experimentally-calibrated fluid-structure interaction (FSI) model was developed to assess the hemodynamic and stress/strain distributions acting on the excessive protrusion extension (PE) of endografts deployed in four young patients underwent TE…
Cardiovascular Risk in Polycythemia Vera: Thrombotic Risk and Survival: Can Cytoreductive Therapy Be Useful in Patients with Low-Risk Polycythemia Ve…
2019
<b><i>Background/Aims:</i></b> Cardiovascular risk factors are not considered in the current scores for evaluation of the thrombotic risk in myeloproliferative neoplasms, and in polycythemia vera (PV) in particular. Cytoreduction is currently not indicated in low-risk patients with PV, despite the absence or presence of cardiovascular risk factors. Our purpose is to highlight how cardiovascular risk factors in patients with PV increase the thrombotic risk both in low- and high-risk patients. <b><i>Methods:</i></b> We collected and analyzed data from 165 consecutive patients with a diagnosis of PV followed at our institution and compared the fr…
Macroscopic assessment of mesorectal excision in rectal cancer
2009
BACKGROUND: High quality of surgical technique and the use of descriptive measures to assess and report surgical proficiency have been shown to influence locoregional tumor control in patients with rectal cancer. In this study, the authors have aimed to audit the implementation of a macroscopic assessment of mesorectal excision (MAME) and to investigate factors that influenced surgical quality and disease recurrence. METHODS: All curative resections for rectal cancer were prospectively evaluated for MAME between 1998 and 2007. Mesorectal specimens were graded into 3 types: complete, nearly complete, and incomplete categories. Univariate and multivariate analyses identified independent risk …
Implication of the Examining Pathologist to Meet the Oncologic Standard of Lymph Node Count after Laparoscopic Lymphadenectomy
2010
<i>Objective:</i> The lymph node number as benchmark in oncologic operations depends on the patient’s anatomy, surgeon’s skill and pathologist’s accuracy. The influence of the pathologist is barely evaluated. <i>Methods:</i> A retrospective analysis of lymph node numbers after 700 laparoscopic lymphadenectomies in correlation to the examining pathologists was done. Three surgeons from the same department performed all operations at 2 campi, where 2 separate pathology institutions exist. Lymph node specimens were assigned randomly to any of the 62 involved pathologists. <i>Results:</i> The mean number of lymph nodes was equal for all surgeons. Lymph node s…
Surgery-triggered and non surgery-triggered Bisphosphonate-related Osteonecrosis of the Jaws (BRONJ): A retrospective analysis of 567 cases in an Ita…
2011
Invasive local procedures are often reported in clinical history of patients suffering from Bisphosphonates-Related Osteonecrosis of the Jaws (BRONJ) but over 40% of spontaneous forms have been also described in literature. We compared age, gender, underlying bone disorders, bisphosphonate therapy, clinical features and surgical outcome of 205 cases (36.2%) of BRONJ non surgery-triggered (group 1) with 362 (63.8%) cases of surgery-triggered forms (group 2). Differences between group 1 and 2 were analysed using Mann-Whitney U and χ2 tests. Statistical analysis was performed using STATA 8. Zoledronate was the most used type of bisphosphonate (63.4% versus 69.0%) and the mandible was the most …
