Duodenopancreatectomy for PDAC Associated with MALS: A Case Report.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive form of pancreatic malignancy which occurs in over 90% of such cases. Pancreaticoduodenectomy (PD) is used with a curative purpose for localized PDAC. Case presentation: A 68-year-old woman presented to our service through a transfer from another service, to be investigated and treated for a head of the pancreas tumor in a tertiary referral hospital. After a complete clinical and paraclinical evaluation, the patient was diagnosed with a PDAC and also with a median arcuate ligament syndrome (MALS). The surgical treatment was considered adequate, therefore, the patient underwent a PD with transmesocolic hepaticojejunostomy, pancreaticogastric anastomosis, precolic end-to-side gastrojejunostomy, Witzel jejunostomy and with the help of the cardiovascular surgery team from the Heart Institute, Cluj- Napoca, an aortohepatic bypass using saphenous vein graft was performed. Conclusion: Bypass was essential because the blood flow in the proper hepatic artery was not restored after sectioning the median arcuate ligament and clamping the gastroduodenal artery. The patient had a favorable outcome. The particularity of the present case consists of the complete occlusion of the celiac trunk by MALS and the total vascularization of the supramesocolic organs due to the superior mesenteric artery through the gastroduodenal artery.

Strokes in Sneddon syndrome without antiphospholipid antibodies.

OBJECTIVE: Sneddon syndrome (SS) is characterized by the association of a livedo reticularis with stroke. Clinicoradiological features of its neurological manifestations, its prognosis, and the frequency of associated cardiac valvulopathy remain poorly known, particularly in the absence of antiphospholipid antibodies (APL). The objectives were to assess the clinicoradiological pattern of SS without APL (SSAPL- ) and its midterm prognosis. METHODS: Clinical data, transthoracic echocardiograms, and brain imaging of 53 consecutive patients (83% women) with SSAPL- , followed up at our institution between 1991 and 2011, were reviewed. RESULTS: Seventy-four strokes were reported; 76% were ischemic strokes (IS), 15% transient ischemic attacks, and 9% hemorrhagic strokes. Heart valve lesions were found in 50% of the cases. Brain imaging showed 177 IS of 3 different types: large territorial (43%), small distal corticosubcortical (14%), and small deep (23%) IS. No significant association was found between the valve involvement and the presence of territorial IS. After a mean follow-up of 7.4 years, 82% of patients had a modified Rankin Scale score ≤ 2. The ischemic event recurrence rate was 20%, with a similar annual rate in the antiplatelet group (3%) compared to the anticoagulation group (2.7%). INTERPRETATION: SSAPL- is not only a neurocutaneous disorder, but is frequently associated with heart valve involvement. The latter does not influence the IS type, which suggests that strokes are caused by vasculopathy of the small and medium-size cerebral arteries. Our results show no progression toward a serious disability in the majority of the cases and a moderate recurrence rate under antiplatelet therapy.

Contributions to the Study of Blood Brain Flux Using Radioactive Tracers.

In this paper, we present an original radiocirculographic method for investigates of cerebral blood flow, which has proven to be very useful, simple, and efficient for studies of brain hemodynamics. Physical considerations on injected radioactive tracer in cardiovascular system, allowed us to state a relationship for the blood flux, F, valued as the amount of fluid-blood that traverses a vascular segment in unit time. All these theoretical facts, along with a host of remarkable clinical results, are presented in a doctoral thesis entitled "The cerebral Hemodynamics in Essential Hypertension and Arteriosclerosis" of the eminent doctor Ioan Mures,an, who died in 1984, at only 50 years old. Using tracers marked with radioactive chrome 51Cr and iodine 131I, it was studied, for patients with various vascular diseases the blood circulation in other territories as an echo of cerebral blood flow. Outstanding results, relating to physiology, diagnosis, and therapy of some diseases, have been obtained. Through intensive collaborations, this method has been operationalized at the University Clinics of Cluj. Here, thousands of patients have been investigated, obtaining quantifiable information which highlighted the patient's condition by emergent and incident blood flows in the global circulatory process and related to other vascular segments.

Two Paradigms for Endovascular Thrombectomy After Intravenous Thrombolysis for Acute Ischemic Stroke.

Importance: Intravenous thrombolysis (IVT) followed by mechanical thrombectomy (MT) is recommended to treat acute ischemic stroke (AIS) with a large vessel occlusion (LVO). Most hospitals do not have on-site MT facilities, and most patients need to be transferred secondarily after IVT (drip and ship), which may have an effect on the neurologic outcome. Objective: To compare the functional independence at 3 months between patients treated under the drip-and-ship paradigm and those treated on site (mothership). Design, Setting, and Participants: This study used a prospectively gathered registry of patients with AIS to select patients admitted through the Saint-Antoine and Tenon (drip and ship) or the Fondation Rothschild (mothership) hospitals from January 1, 2013, through April 30, 2016. The study included patients older than 18 years treated with bridging therapy for AIS with LVO of the anterior circulation. Among the 159 patients who received MT at the mothership, 100 had been transferred after IVT from the drip-and-ship hospitals and 59 had received IVT on site. Main Outcomes and Measures: The main outcome was 3-month functional independence (modified Rankin scale score ≤2). Both groups were compared using a multivariate linear model, including variables that were significantly different in the 2 groups. Results: During the study period, 497 patients were hospitalized at the drip-and-ship and mothership hospitals for an AIS eligible to reperfusion therapy; 11 patients had a basilar artery occlusion and were excluded, leaving 100 patients in the drip-and-ship group (mean age, 73 years; age range, 60-81 years; 57 men [57.0%]) and 59 in the mothership group (mean age, 70 years; age range, 58-82 years; 29 men [49.2%]). The proportion of patients with a favorable neurologic outcome at 3 months was similar in both groups (drip and ship, 61 [61.0%]; mothership, 30 [50.8%]; P = .26), even after adjusting the analysis for the baseline National Institutes of Health Stroke Scale score, diffusion-weighted imaging Alberta Stroke Program Early Computed Tomography Score, and general anesthesia (P = .82). Patients had less severe conditions in the drip-and-ship group (median baseline National Institutes of Health Stroke Scale score, 15 vs 17 [P = .03]; median diffusion-weighted imaging Alberta Stroke Program Early Computed Tomography Score, 7.5 vs 7 [P = .05]). Process times were longer in the drip-and-ship group (onset-to-needle time, 150 vs 135 minutes; onset-to-puncture time, 248 vs 189 minutes; and onset-to-recanalization time, 297 vs 240 minutes; P < .001). Both groups were similar in terms of substantial recanalization (Thrombolysis in Cerebral Ischemia scores 2B to 3; drip and ship, 84 [84.0%]; mothership, 47 [79.7%]; P = .49) and symptomatic hemorrhagic transformation (drip and ship, 2 [2.0%]; mothership, 2 [3.4%]; P = .63). Conclusions and Relevance: This study found that patients treated under the drip-and-ship paradigm also benefit from bridging therapy, with no statistically significant difference compared with those treated directly in a comprehensive stroke center.

A very rare association between giant right atrial myxoma and patent foramen ovale. Extracellular matrix and morphological aspects: a case report.

We report a case of sporadic giant cardiac myxoma with a rare localization in the right atrium, operated in our Service, in a 73-year-old female patient who also presented a patent foramen ovale and a history of ischemic stroke in the year prior to current admission. Intra-operatively, the tumor had a very friable, gelatinous aspect, with a high potential for embolization due to its reduced consistency. The present paper refers to clinical, histochemical and immunohistochemical particularities, as well as to macroscopic and microscopic characteristics of the cardiac myxoma, emphasizing the extracellular matrix aspects, and without leaving out the cellular components of this rare tumor, with possible inference in the management of this disease. The authors present their own observations related to the data from the literature. Also, there are some particularities of the case which justify the current presentation.

The Challenging Diagnosis of Non-Community-Acquired Pneumonia in Non-Mechanically Ventilated Subjects: Value of Microbiological Investigation.

BACKGROUND: Early recognition and an attempt at obtaining microbiological documentation are recommended in patients with non-community-acquired pneumonia (NCAP), whether hospital-acquired (HAP) or health care-associated (HCAP). We aimed to characterize the clinical features and microbial etiologies of NCAP to assess the impact of microbiological investigation on their management. METHODS: This was a prospective 1-y study in a university hospital with 141 non-mechanically ventilated subjects suspected of having HAP (n = 110) or HCAP (n = 31). RESULTS: Clinical criteria alone poorly identified pneumonia (misdiagnosis in 50% of cases). Microbiological confirmation was achievable in 80 subjects (57%). Among 79 microorganisms isolated, 28 were multidrug-resistant aerobic Gram-negative bacilli and group III Enterobacteriaceae and 6 were methicillin-resistant Staphylococcus aureus. Multidrug-resistant aerobic Gram-negative bacilli accounted for one third of the microorganisms in early-onset HAP and for 50% in late-onset HAP. Methicillin-resistant S. aureus was most often recovered from subjects with HCAP. Inappropriate empirical antibiotics were administered to 36% of subjects with confirmed pneumonia. Forty subjects were admitted to the ICU, 13 (33%) of whom died. Overall, 39 subjects (28%) died in the hospital. CONCLUSIONS: Integrating the microbiological investigation in the complex clinical diagnostic workup of patients suspected of having NCAP is mandatory. Respiratory tract specimens should be obtained whenever possible for appropriate management.

Surgical outcomes in native valve infectious endocarditis: the experience of the Cardiovascular Surgery Department - Cluj-Napoca Heart Institute.

BACKGROUND AND AIMS: The introduction of Duke's criteria and the improvement of imaging methods has lead to an earlier and a more accurate diagnosis of infectious endocarditis (IE). The options for the best therapeutic approach and the timing of surgery are still a matter of debate and require a close colaboration between the cardiologist, the infectionist and the cardiac surgeon. METHODS: We undertook a retrospective, descriptive study, spanning over a period of five years (from January 1st, 2007 to December 31st, 2012), on 100 patients who underwent surgery for native valve infectious endocarditis in our unit. RESULTS: The patients' age varied between 13 and 77 years (with a mean of 54 years), of which 85 were males (85%). The main microorganisms responsible for IE were: Streptococcus Spp. (21 cases - 21%), Staphylococcus Spp. (15 cases - 15%), and Enterococcus Spp. (9 cases - 9%). The potential source of infection was identified in 26 patients (26%), with most cases being in the dental area (16 cases - 16%). The lesions caused by IE were situated in the left heart in 96 patients (96%), mostly on the aortic valve (50 cases - 50%). In most cases (82%) we found preexisting endocardial lesions which predisposed to the development of IE, most of them being degenerative valvular lesions (38 cases - 38%). We performed the following surgical procedures: surgery on a single valve - aortic valve replacement (40 cases), mitral valve replacement (19 cases), mitral valve repair (1 case), surgery on more than one valve - mitral and aortic valve replacement (20 cases), aortic and tricuspid valve replacement (1 case), aortic valve replacement with a mechanical valve associated with mitral valve repair (5 cases), aortic valve replacement with a biological valve associated with mitral valve repair (2 cases), and mitral valve replacement with a mechanical valve combined with De Vega procedure on the tricuspid valve (1 case). In 5 patients (5%) the bacteriological examination of valve pieces excised during surgery was positive. In 3 cases it matched the germ identified in the hemocultures, and in 2 cases it evidenced another bacterium. CONCLUSION: The overall mortality of 5% is well between the limits presented in literature, being higher (30%) in patients who required emergency surgery. For the patients who return into our clinic with prosthetic valve endocarditis, the mortality after surgery was even higher (50%).

Drainage of cerebral abscesses prior to valve replacement in stable patients with acute left-sided infective endocarditis.

Despite the medical and surgical advancements in the treatment of patients with acute infective endocarditis (IE), neurologic complications remain problematic. They can arise through various mechanisms consisting of stroke or transient ischemic attack, cerebral hemorrhage, mycotic aneurysm, meningitis, cerebral abscess, or encephalopathy. Most complications occur early during the course of IE and are characteristic to left-sided pathology of native or prosthetic valves. We present a case of a 46 year old male patient who presented to our clinic with mitral valve IE caused by coagulase negative staphylococcus. Although under correct antibiotic treatment, he continued to be feverish and started to present unspecific neurological symptoms (amnesia, confusion, asthenia and general malaise). The cerebral magnetic resonance imaging (MRI) revealed multiple cerebral abscesses. Because the patient was hemodynamically stable we decided to address the cerebral abscess first and the cardiac lesion second. The patient made a full recovery after undergoing antibiotic treatment and surgical procedures of drainage of the cerebral abscess and mitral valve replacement. After reviewing the literature regarding the management of patients with IE and cerebral complications and based on this particular case, we conclude that in select cases of stable patients with cerebral abscess and IE, the neurological lesion should always be addressed first and cardiac surgery should be performed second.

Papillary fibroelastoma of the pulmonary valve: a case report.

Papillary fibroelastoma is a rare, benign cardiac tumor typically found on the heart valves, which is usually discovered incidentally on echocardiography. The clinical presentation of cardiac papillary fibroelastoma varies from no symptoms to severe embolic sequelae. We report the case of a 55-year-old female patient, with a suspicion of pulmonary embolism one year before, presently admitted to the hospital for mild respiratory symptoms; the trans-esophageal echocardiography (TEE) revealed a 10/10 mm tumoral mass attached on the pulmonary valve, confirmed also by the contrast-enhanced magnetic resonance imaging (MRI). Considering the embolization risk, we decided surgical removal, with favorable outcome. The pathologic exam of the removed tumor established the diagnosis of papillary fibroelastoma. The clinical and imaging assessment one month after surgery were within normal limits. The surgical removal of the papillary fibroelastoma of the pulmonary valve is mandatory for the elimination of embolization risk. The intervention is relatively secure, with low rates of morbidity and mortality.

Frequency and predictors of post-traumatic stress disorder after stroke: a pilot study.

OBJECTIVE: Few data exist about post-stroke symptoms of post-traumatic stress disorder (sPTSD) and none on DSM-IV formally diagnosed PTSD (fdPTSD). We investigated the frequency and predictors of sPTSD and fdPTSD 1-6 months after a nondisabling ischemic stroke (IS) or transient ischemic attack (TIA). METHODS: Consecutive patients were assessed for sPTSD (Impact of Events Scale-Revised, IES-R, significant if >30) and fdPTSD (PTSD-Interview). We recorded sociodemographic factors, stroke features (including severity of the initial deficit, persistent disability, localization), associated mood changes, peritraumatic reactions during the stroke (Peritraumatic Distress Inventory (PDI) for fear and distress, Peritraumatic Dissociative Experience Questionnaire for cognitive appraisal), and psychiatric history. Patients with sPTSD and fdPTSD were compared to patients with IES-R<30. RESULTS: Among the 40 patients (65% male, mean age 52 years) studied post-IS (n=30; mean initial NIHSS 4) or TIA, 25% had sPTSD, including 10% with fdPTSD. sPTSD was more frequent in women (p=0.02), patients with intense peritraumatic reactions especially on PDI (p=0.001) or identified prior depression and anxiety (p=0.007). No other demographic factors or stroke characteristics were associated with sPTSD. Forty percent of sPTSD patients were depressed versus none of the controls (p<0.002). All fdPTSD patients had ≥ 3 prior psychiatric co-morbidities. CONCLUSIONS: After nondisabling IS or TIA, sPTSD is frequent, with fdPTSD for 10%. Patients with intense peritraumatic reactions, women, and those with prior psychiatric morbidity, require particular attention to detect sPTSD.

Very early neurologic improvement after intravenous thrombolysis.

OBJECTIVE: To evaluate whether very early neurologic improvement (VENI) after intravenous (i.v.) recombinant tissue plasminogen activator (rt-PA) perfusion in patients with acute ischemic stroke (AIS) predicts favorable outcome at 3 months. DESIGN: Retrospective analysis of prospective data. SETTING: Stroke registry at the Stroke Unit, Tenon University Hospital. PATIENTS: We analyzed consecutive patients with AIS treated with i.v. rt-PA between November 11, 2002, and December 24, 2007. MAIN OUTCOME MEASURES: VENI at 1 hour was defined as a National Institute of Health Stroke Scale score of 0 at the end of rt-PA perfusion or an improvement of 5 or more points compared with baseline. Favorable outcome was defined as a modified Rankin Scale score of 1 or less at 3 months. RESULTS: Of 120 patients with AIS treated with i.v. rt-PA, 22 (18.3%) had VENI after i.v. rt-PA perfusion. Favorable outcome was observed in 15 patients with VENI (68.2%) and in 29 patients without VENI (29.6%) (P < .001). No symptomatic intracerebral hemorrhage occurred in patients with VENI. Mortality rates were 0% in the patients with VENI and 17.3% in patients without VENI. Baseline scores for VENI (adjusted odds ratio, 6.23; 95% confidence interval, 2.03-19.13; P = .001) and the National Institute of Health Stroke Scale (0.83; 0.76-0.91; P < .001) were the only 2 factors associated with favorable outcome (modified Rankin Scale score of ≤1). CONCLUSIONS: VENI at the end of i.v. rt-PA perfusion in patients with AIS independently predicts favorable outcome at 3 months.
