RESUMO

INTRODUCTION: Frontal sinus enlargement has been classified into hypersinus, pneumosinus dilatans and pneumocele. CASE REPORT: A young male presented with aesthetic concerns regarding his forehead swelling. The patient had no functional disturbances. Radiographic assessment proved expansion of the frontal sinus with extreme thinning of the frontal bone. DISCUSSION: The causes of frontal sinus expansion have been listed along with a proposed management plan for each type. If blockage is suspected, functional endoscopic sinus surgery can alleviate the blockage. Open surgery is indicated when the element presents as an aesthetic concern. Obliteration of the sinus is indicated with NF obstruction. And reshaping of the anterior table is the mainstay to correct the enlargement. CONCLUSION: Frontal sinus enlargement regardless of the cause can be tackled using well known principles. We believe that every plastic surgeon should have a basic understanding of frontal sinus enlargement and its management.

RESUMO

BACKGROUND: Phase III randomized controlled trials (RCTs) are the cornerstone of evidence-based oncology. However, there is no exhaustive review describing the radiotherapy RTCs characteristics. The objective of the present study was to describe features of all phase III RCTs including at least a radiation therapy. METHODS AND MATERIALS: Requests were performed in the Medline database (via PubMed). The latest update was performed in April 2016, using the following MESH terms: 'clinical trials: phase III as topic', 'radiotherapy', 'brachytherapy', as keywords. RESULTS: A total of 454 phase III RCTs were identified. Studies were mainly based on open (92.1%) multicenter (77.5%) designs, analyzed in intend to treat (67.6%), aiming at proving superiority (91.6%) through overall survival assessment (46.5%). Most frequently studied malignancies were head and neck (21.8%), lung (14.3%) and prostate cancers (9.9%). Patients were mainly recruited with a locally advanced disease (73.7%). Median age was 59 years old. Out of 977 treatment arms, 889 arms experienced radiotherapy, mainly using 3D-conformal radiotherapy (288 arms, 32.4%). Intensity-modulated techniques were tested in 12 arms (1.3%). The intervention was a non-cytotoxic agent addition in 89 studies (19.6%), a radiation dose/fractionation modification in 74 studies (16.3%), a modification of chemotherapy regimen in 63 studies (13.9%), a chemotherapy addition in 63 studies (13.9%) and a radiotherapy addition in 53 trials (11.7%). With a median follow-up of 50 months, acute all-grade and grade 3-5 toxicities were reported in 49.6% and 69.4% of studies, respectively. Radiotherapy technique, follow-up and late toxicities were reported in 60.1%, 74%, and 31.1% of studies, respectively. CONCLUSION: Phase III randomized controlled trials featured severe limitations, since a third did not report radiotherapy technique, follow-up or late toxicities. The fast-paced technological evolution creates a discrepancy between literature and radiotherapy techniques performed in daily-routine, suggesting that phase III methodology needs to be reinvented.

RESUMO

INTRODUCTION: The aim of this study was to appreciate the place and role of geriatric assessment in elderly patients with prostate cancer. MATERIALS AND METHODS: We performed a retrospective analysis of prostate cancer patients who underwent geriatric assessment during the therapeutic management from 2008 to 2014. Patient, tumor, treatment characteristics and their associated toxicity as well as the parameters of geriatric assessment were studied. The occurrence of geriatric assessment within the 3 months preceding a therapeutic decision was reviewed. RESULTS: Data of seventy-four patients were analyzed with a median follow-up of 15.6 years. The average age at diagnosis was 74.3 and 80.6 at the geriatric assessment. At the time of the geriatric assessment 64 patients had metastatic disease, 39 were in poor condition more than 50% of patients had walking ability disorders. Thirteen patients underwent radical surgery, 28 received radiotherapy, 30 patients had chemotherapy and hormonotherapy was prescribed for 72 patients. The geriatric assessment, requested on average 15 years after diagnosis, was not carried out within the 3 months preceding treatment decision for 55 patients. CONCLUSION: The recourse to geriatric assessment is predominantly used to endorse a decision of supportive care for elderly patients with prostate cancer. An early intervention by a geriatrician consultant for the initial management and then at each therapeutic event is a sine qua non condition for efficient personalized therapeutic management suitable to every patient according to physiological age. LEVEL OF EVIDENCE: 4.

RESUMO

Biermer disease or pernicious anemia is an autoimmune atrophic gastritis characterized by the lack of secretion of gastric intrinsic factor. This leads to an insufficient absorption of vitamin B12 in the ileum. Clinical manifestations are mainly hematologic. Neuropsychiatric manifestations are known but are less frequent especially early in the disease. Inaugural neuropsychiatric arrays are rare and various thus making diagnosis difficult. In this article, we report through two clinical cases different neuropsychiatric manifestations revealing pernicious anemia. Mrs. C.O., aged 56, presented after surgery for gallstones, an acute psychiatric array associated with gait disorders. She had no history of neurological or psychiatric problems. The psychiatric interview revealed delirious syndrome, depressive symptoms and anxiety. Neurological examination noted a flaccid paraplegia with peripheral neuropathic syndrome and myoclonus in the upper limbs. At the full blood count, a macrocytosis (VGM: 112.2fl) without anemia was found. The level of vitamin B12 in the blood was low. Cerebro-spinal MRI was suggestive of a neuro-Biermer and showed hyper signal in the cervical cord on T2-weighted sagittal section. In axial section, hyper signal appears at the posterior columns in the form of V. There were no brain abnormalities. A sensorimotor axonal polyneuropathy was diagnosed. The patient received vitamin B12 intramuscularly for ten days associated with neuroleptic treatment. Mrs. R.M., aged 40, was brought to the psychiatry consultation for acute behavioral disorders progressively worsening over a month. An anxiety syndrome, depressive syndrome and delirious syndrome were identified. Neurological examination showed a posterior cordonal syndrome with quadripyramidal syndrome. Full blood count showed a macrocytic anemia. Serum B12 level was collapsed. Cerebro-spinal MRI was normal. She received vitamin B12 with clinical and biological improvement. Features of pernicious anemia vary according to studies and age range. Digestive and hematological manifestations are well known. Neurological and psychiatric manifestations of pernicious anemia were also described in the early literature. They can be the initial symptoms or the only ones. However, inaugural neuropsychiatric features are often unrecognized. The most common psychiatric symptoms were depression, mania, psychotic symptoms, cognitive impairment and obsessive compulsive disorder. Neurological involvement includes mainly combined spinal sclerosis, peripheral neuropathy and dementia. Cerebellar ataxia and movement disorders are reported less often. Severity of neuropsychiatric features and therapeutic efficacy depends on the duration of signs and level of B12 deficiency. Macrocytic anemia may lack. Neuropsychiatric manifestations could be isolated or be the first manifestation of vitamin deficiency and occur without any hematological or gastrointestinal context. Pernicious anemia and serum B12 assay should be discussed in all patients with organic mental disorders, atypical psychiatric symptoms and fluctuation of symptomatology. Nevertheless, B12 level could be normal in genuine pernicious anemia diseases and macrocytic anemia may lack. Substitutive vitaminotherapy is required when diagnosis is strongly suspected and etiologic assessment is negative.

RESUMO

We address a real-world optimization problem: the scheduling of a Bank Information Technologies (IT) staff. This problem can be defined as the process of constructing optimized work schedules for staff. In a general sense, it requires the allocation of suitably qualified staff to specific shifts to meet the demands for services of an organization while observing workplace regulations and attempting to satisfy individual work preferences. A monthly shift schedule is prepared to determine the shift duties of each staff considering shift coverage requirements, seniority-based workload rules, and staff work preferences. Due to the large number of conflicting constraints, a multiobjective programming model has been proposed to automate the schedule generation process. The suggested mathematical model has been implemented using Lingo software. The results indicate that high quality solutions can be obtained within a few seconds compared to the manually prepared schedules.

RESUMO

Targeted therapies (TT) represent since 10 years, an interesting progress in oncology for many cancers in adjuvant, neoadjuvant or palliative situation. The development of this new class of drugs, with an original mechanism of action, their easy administration, mainly per os, and a particular toxicity profile different from "classical" chemotherapy (CT) leads them entering in the therapeutic arsenal of breast, digestive tract, lung and hematologic cancers, in association with CT. Medical oncologists took rapidly the train of TT, managing a new and original skin, digestive, cardiovascular, endocrine and pulmonary toxicity profile, that remains relatively less important than "classical" CT.

RESUMO

INTRODUCTION: In Tunisia, as elsewhere in the world, severe forms of acute respiratory distress syndrome (ARDS) related to SARS-Covid19 have been observed. When the usual means of resuscitation were no longer sufficient, the implementation of the Extracorporeal membrane oxygenation or ECMO was needed. AIM: The whole problem of the management of these patients in this pandemic period has been to manage the operation of the ECMO machine, usually reserved for expert and specialized centers in the field. METHODS: The cardio-vascular surgery department of La Rabta teaching hospital of Tunis has tried the experience of management of ECMO implanted in the different reanimations of Tunis, remotely, using telemedicine and social networks. Thus, a Facebook-Messenger discussion group was created and enabled the management of patients under ECMO via video conferencing in real time involving all stakeholders. RESULTS: A call was made whenever the physician needed it. The video provided an opportunity to discuss with surgeons and perfusionists in real time the complications or problems of these patients. Their clinical status was continuously shared on the focus group. Following the instructions of the expert surgeons and the exchanges made on the group, the reanimator could then intervene on this or that parameter. CONCLUSION: Social media have invaded everyone's daily lives and health professionals are not exception to this trend. The Covid-19 pandemic has only strengthened this digital alternative with the goal of efficiency and patient interest. While their use in a professional setting offers many advantages, it must nevertheless be done in compliance with the rules of ethics and bring real added value.

RESUMO

Superior vena cava syndrome is the clinical expression of the obstruction of the superior vena cava reducing the blood flow. Malignant etiologies are the most common. Its management is multidisciplinary and despite the progress of endovascular procedures, conventional surgery retains its place in certain indications. Mediastinal fibrosis secondary to tuberculosis lymphadenopathy may be associated with superior vena cava syndrome. In the presence of symptomatic SVCS associated with extensive mediastinal fibrosis compressing the superior vena cava with sub occlusive thrombosis, conventional surgery remains a treatment option, with cavo-venous derivation by prosthetic bypass.

RESUMO

AIM OF THE STUDY: The purpose of our study was to review the population at risk of upper limb arterial injury, to determinate the rate of upper limb salvage and the predictive factors of limb loss. METHODS: This was a retrospective study, involving 128 patients with upper extremity arterial trauma operated between January first, 2006 and June 30, 2017. Exclusion criteria were arterial ligation, primary limb amputation and arterial iatrogenic injuries. End points were immediate technical success, primary patency and limb salvage rate. RESULTS: The average age was 27.7 years with a sex ratio M/F=41, causes of trauma were self-inflicted wounds (51%), assaults (23%), road traffic accidents (10%), work accidents (9%) and domestic accidents (7%). Injured arteries were brachial (66.5%) usually because of self-inflicted injuries; arteries of the forearm (31%) and axillery arteries (2.5%). The techniques of arterial repair were vein graft interposition in 52% of cases, end-to-end anastomosis in 23%, primary arterial repair in 21% and venous patch in 4%. Eight reconstructions occluded during the first week (6.25%). Four patients required secondary amputation and limb salvage rate was 96.8%. After a median follow-up time of 62 days, only 21% were followed at 3 months. Mechanism of injury, soft tissue loss and arterial reconstruction thromboses were selected as factors influencing the rate of limb salvage. One death occurred at day 14 secondary to multi-component poly-trauma. CONCLUSION: Prompt diagnosis, appropriate multidisciplinary management of the upper extremity arterial trauma and a readiness to revise the vascular repair early in the event of failure will maximize patient survival and upper extremity salvage. Associated soft tissue injury is a poor limb salvage factor.

RESUMO

INTRODUCTION: Despite the success of angioplasty of the iliac artery, this technique remains associated with significant amputation rates. The purpose of this study was to identify predictive factors for lower limb amputation after iliac angioplasty in patients with critical ischemia. METHODS: We reported a retrospective study including patients who successfully underwent angioplasty of the iliac artery between 2014 and 2018. The primary endpoint was limb salvage at 1 month. The variables were studied in univariate and multivariate analysis. RESULTS: Our study included 86 patients. The median age was 57±10 and the sex ratio was 4.7. Cardiovascular risk factors were represented by smoking in 14 cases (16.3%), diabetes in 25 cases (29.1%), arterial hypertension in 2 cases (2.3%) and dyslipidemia in 2 cases (2.3%). Seventy patients (81.3%) were classified as stage 4 according to the Leriche and Fontaine classification and 16 patients (18.7%) were classified as stage 3. The lesions were stenosing in 48 cases (55.8%) and occlusive in 38 cases (44.2%). These lesions were classified according to the TASC classification "Trans-Atlantic-Society-Consensus" in TASC A-B in 61 cases (70.9%) and TASC C-D in 35 cases (29.1%). Distal arteritis was found in 8 cases (9.3%). Balloon angioplasty was performed in 36 cases (41.8%) and angioplasty stenting in 50 cases (58.2%). At 1 month, the amputation rate was 9.3%. Univariate analysis showed that diabetes and smoking were the most important factors associated with amputation (respectively P=0.007, OR=9.31, 95% CI=[1.73-50.07] and P=0.022; OR=6.8; 95% CI=[1.46 to 31.61]). Multivariate analysis showed that diabetes and distal arteritis were the predictive factors for amputation (respectively P=0.034, OR=21.06, 95% CI=[1.25 to 354.46] and P=0.008, OR=11,61, 95% CI=[1.88 to 71.69]). CONCLUSION: Diabetes and distal arteritis are the predictive factors for lower limb amputation after iliac angioplasty.

RESUMO

Management of iliac stent thrombosis is challenging. Open surgical repair may be indicated when intraluminally stent catheterization is difficult to perform. The present review reports the crush stent recanalization technique illustrated with the management of a patient with critical limb ischemia associated to iliac stent thrombosis. Crush stent technique has been described in interventional cardiology but remains rarely performed. Few reported cases described this technique for peripheral arterial recanalization, that is stenting through the subintimal space around an occluded stent.

RESUMO

PURPOSE: Patients frequently report asthenia during radiation. The present study aimed at identifying the correlation between numerous clinical and tumoral factors and asthenia in breast and prostate cancer patients treated by curative radiotherapy. MATERIALS AND METHODS: A retrospective study was conducted at the Lucien Neuwirth Cancer Institute (France). All breast and prostate cancer patients undergoing curative radiotherapy during 2015 were screened (n=806). Patient's self-evaluation of asthenia and radiotherapy tolerance was assessed through verbal analogic scale (0/10 to 10/10). Data about toxicities, travel distance and travel time, tumor's characteristics, radiotherapy treatment planning, previous cancer therapies, were collected from medical records. RESULTS: 500 patients were included (350 in the breast cancer group and 150 in the prostate cancer group). In all, 86% of patients in the breast cancer group reported asthenia, with a 5/10 median score. In all, 54% of patients in the prostate cancer group reported asthenia, with a 2/10 median score. Univariate analysis showed correlation between asthenia and radiotherapy tolerance as well as tumor staging, in the prostate cancer group. No other correlation was evidenced. CONCLUSION: Radiotherapy-related fatigue is a common side effect. This study showed that most of the factors related to patients or disease that are commonly used to explain fatigue during curative treatments, seem finally to be not correlated with asthenia.

RESUMO

INTRODUCTION: Conventional open repair of a traumatic aortic isthmic rupture is associated with a significantly high mortality and morbidity rates. Thoracic endovascular aortic repair (TEVAR) is currently often performed because it is a less invasive treatment than surgery. The aim of this study was to evaluate short and mid-term results of TEVAR in traumatic aortic isthmic rupture. METHODS: This is a retrospective study conducted between 2010 and 2018 including patients who underwent TEVAR for traumatic aortic isthmic rupture. RESULTS: Thirty-six consecutive patients were included. All patients had sustained a violent blunt chest trauma after a sudden deceleration with associated injuries. The injury severity score (ISS) was 40 (14-66). All patients were hemodynamically stable at admission. We deployed thoracic aorta stent grafts with a mean diameter of 26mm (18-36). The procedural success rate was 100%. We reported one intra-operative complication which was a distal migration of the graft, managed by an implantation of an aortic extension graft. On the first postoperative day, one patient presented an acute lower limb ischemia, probably due to the surgical femoral access, treated with an embolectomy with a Fogarty catheter with satisfactory results. The mean follow-up was 40.41 months (6.5-96). The mortality and paraplegia rates were 0% at one month and during the follow-up period. We reported a case of kinking of the graft that occurred at 6 months. No cases of endoleak neither re-intervention were reported. CONCLUSION: TEVAR is a safe and a reliable method for the treatment of sub-acute traumatic thoracic aortic injuries.

RESUMO

The incidence of oropharyngeal cancer induced by human papillomavirus (HPV) infection is steadily increasing in developed countries. These tumors are more chemoradiosensitive and have a better prognosis than HPV-negative one. In addition, they occur in younger and better-off patients with longer life expectancy. Current radiotherapy and chemotherapy protocols are currently being questioned as they may expose HPV-positive patients to excessive treatment and unnecessary toxic effects. Less intensive treatment regimens could possibly achieve similar efficacy with lower toxicity and improved quality of life. The aim of this work was to summarize the knowledge on these tumors and their implications for radiation oncologists. In this update, we will discuss ongoing de-escalation trials and highlight the issues raised by these studies. We will also comment on the results of recently published de-intensification studies. Three main strategies are analyzed in the present article: the de-escalation of the drug associated with radiotherapy, the de-escalation of the radiotherapy dose (in concomitant chemoradiotherapy, after induction chemotherapy, in a postoperative setting) and de-escalation of radiation target volumes. Our findings ultimately indicate that clinicians should not change the management of oropharyngeal cancer patients outside of clinical trials.

RESUMO

The aim of this study was to evaluate the results of conservative surgical treatment of the aneurysmal complications of arteriovenous hemodialysis fistulae and to determine the factors predictive of long- and mid-term patency of treated fistulae. The surgical treatment was mainly based on caliber reduction and reconstruction. METHODS: This was a descriptive retrospective study with a five-year duration, going from January 2013 to December 2018. This study included 40 patients presenting aneurysmal complications of their hemodialysis vascular access who were treated with aneurysmorrhaphy. RESULTS: The mean age of the aneurysmal-complicated hemodialysis vascular access was 42 months. The indications for treatment were puncture-related difficulties in 42.5% of cases, rapid increase of the aneurysmal diameter in 27.5%, skin thinning in 25% and aneurysmal rupture in 5%. The mean aneurysmal course was 6.6 months with an average diameter of 3.25cm at the moment of management. The initial technical success rate was 100%. Twenty patients had complications in the postoperative period. Patency rates at 3, 6, 12 and 24 months were 89.5%, 81.6%, 71% and 63.1%, respectively. Factors predictive of thrombosis were diabetes (P=0.001), peripheral arterial disease (P=0.003), number of punctures per week (P=0.003) and context of emergency presentation (P=0.001). CONCLUSION: Aneurysmorrhaphy seems to be the best conservative surgical treatment for aneurysmal complications of hemodialysis vascular access fistulae. This surgical approach allows us to conserve the native autologous vascular access and spare the patient's venous network.

RESUMO

Bilateral absence of the superior vena cava (SVC) is an uncommon congenital vascular anomaly, mainly asymptomatic, usually undetected, and often associated with other cardiac anomalies. Though usually harmless and totally innocent, this vascular anomaly might complicate cardiovascular surgery, the insertion of a central venous catheter and the transvenous placement of a pacemaker. This SVC anomaly is still not well known, underdiagnosed and its incidence is much higher than described. A better understanding of this anomaly and its detection could play a key role in avoiding its potential complications. We are sharing a case of a female adult, with no medical history, who presented herself to the department of visceral surgery with a collateral venous circulation of the upper thorax, that was at first, mistaken for a portal hypertension syndrome, findings were pushed to finally conclude a bilateral absence of the SVC.

RESUMO

INTRODUCTION: Acute upper limb ischemia is a medical and surgical emergency. Studies that have reported revascularization results in acute upper limb ischemia are rare. For this reason, the revascularization delay has remained poorly defined. The purpose of this study was to evaluate surgery results of acute upper limb ischemia related to revascularization delay. METHODS: We report a retrospective study of patients operated for acute upper limb ischemia between 2008 and 2016. Patients with thrombotic, traumatic or iatrogenic ischemia were excluded from this study. Patients were divided into two groups (those operated before 12hours and those operated after 12hours). A statistical analysis was performed to compare surgery results between the two groups in terms of limb salvage rate and neurological sequelae rate. RESULTS: Our population consisted of 138 patients. The average age was 69 [31,92]. There were 90 women and 48 men. The mean revascularization delay was 20hours [2,240]. Seventy-six patients were operated on before 12hours and 62 patients after 12hours. At one month, the mortality was 1.4% and the morbidity was 5.7%. The overall limb salvage rate was 86.9% and the overall neurologic sequelae rate was 31.8%. Statistical analysis showed that there was no significant difference between patients operated before or after 12hours in terms of limb salvage (86.8% versus 87%, P=0.258). However, there was a statistically significant difference in terms of neurological sequelae in favor of patients operated after 12hours (15.7% versus 51.6%, P=0.012). CONCLUSION: Revascularization of acute embolic upper limb ischemia is often associated with good results even if performed late. Beyond 12hours of ischemia, amputation rate is not significantly higher, however, the rate of neurological sequelae can be high.

RESUMO

Behçet's disease is a rare chronic systemic inflammatory disease. It is more common in Turkey, North Africa and Japan. The incidence of vascular involvement (angio-Behçet) is 7 to 38%. The gluteal localization of angio-Behçet is rarely reported and could be revealed late. Aside from aneurysmal rupture, nerve compression with pain and lower limb impotence could be the main clinical signs. Because of the deep location of the lesion, management of this disease can be difficult. The classic surgical treatment remains the gold-standard especially in case of extreme urgency, non-feasibility of endovascular treatment and especially in case of associated nerve compression. We report the case of a 45-year-old man with a history of pulmonary angio-Behcet, who underwent emergency surgery for a huge false aneurism of a collateral of the hypogastric artery treated via a double anterior and posterior approach with good outcome.
