Good outcome of liver transplantation in patients with pre-existing renal cell carcinoma.

The presence of a pre-existing or recent extra-hepatic solid tumor was considered for a long time as an absolute contraindication to liver transplantation, by fear of futility with an unacceptable increase in non-liver-related mortality. However, cancer-related mortality in solid malignancies is heterogeneous, and experts suggest that case-by-case multidisciplinary decisions should be made. Here, we report the cases of 3 patients with favorable oncological and liver outcome in patients with renal cell carcinoma detected during pre-transplant evaluation that nonetheless underwent liver transplantation.

[Pilonidal cyst of the scalp following a single minor trauma]. / Kyste pilonidal du scalp secondaire à un traumatisme inaperçu : à propos d'un cas.

The pilonidal cyst is an inflammatory disease occurring when a hair follicle penetrates inside a surgical wound. Uncommon in the scalp region, the pilonidal sinus is typically encountered in the sacrococcygeal regions. A single minor trauma of the scalp can be an inductor factor. The surgical treatment includes one-piece excision of the cyst followed by direct closure. We report a case of a 4-year-old child presenting a pilonidal sinus of the scalp following a single minor trauma.

Traitement Chirurgical Des Brides Cervicales Post Brûlure: À Propos De 47 Cas.

When their treatment is not optimal, deep cervical burns often develop retractions, ranging between simple vertical retractions to major global ones. They generate functional, aesthetic and psychological sequelae. Surgical treatment, adapted to both the patient and the type of retraction, has several goals including restoring the neck-chin angle, restoring a correct aesthetic aspect, and allowing social rehabilitation. In our unit, we managed 47 patients (mean age 22) with neck contractures over 8 years, from 2012-2020. Scald is more frequent in children while flame burns prevail in adults. Most (58%) patients healed spontaneously. Moderate and severe contractures (Achauer's classification) accounted for 30.6 and 38.8% respectively. In most (94%) patients, the contracture leads to a distortion of the neck-chin angle and limits the extension of the neck. Surgery techniques were skin grafts (67.3%), local plasties (24.5%) and flaps (8.2%). During the follow-up, results were considered as good in 83%, acceptable in 8.5%, while 8.5% needed another surgery. Plasties (Z, IC, VY…) and local flaps (with or without skin expansions) are indicated in minor contractures. Authors still debate on the best technique (graft or flap) for severe and major ones. Post-operative rehabilitation is a cornerstone for good results.

High incidence of postoperative infections after pancreaticoduodenectomy: A need for perioperative anti-infectious strategies.

OBJECTIVES: Postoperative infections occur frequently after pancreaticoduodenectomy, especially in patients with bile colonization. Recommendations for perioperative anti-infectious treatment are lacking, and clinical practice is heterogenous. We have analyzed the effects of bile colonization and antibiotic prophylaxis on postoperative infection rates, types and therapeutic consequences. METHODS: Retrospective observational study in patients undergoing pancreaticoduodenectomy with intraoperative bile culture. Data on postoperative infections and non-infectious complications, bile cultures and antibiotic prophylaxis adequacy to biliary bacteria were collected. RESULTS: Among 129 patients, 53% had a positive bile culture and 23% had received appropriate antibiotic prophylaxis. Postoperative documented infection rate was over 40% in patients with or without bile colonization, but antibiotic therapy was more frequent in positive bile culture patients (77% vs. 57%, P=0,008). The median duration of antibiotic therapy was 11 days and included a broad-spectrum molecule in 42% of cases. Two-thirds of documented postoperative infections involved one or more bacteria isolated in bile cultures, which was associated with a higher complication rate. While bile culture yielded Gram-negative bacilli (57%) and Gram-positive cocci (43%), fungal microorganisms were scarce. Adequate preoperative antibiotic prophylaxis according to bile culture was not associated with reduced infectious or non-infectious complication rates. CONCLUSION: Patients undergoing pancreaticoduodenectomy experience a high rate of postoperative infections, often involving bacteria from perioperative bile culture when positive, with no preventive effect of an adequate preoperative antibiotic prophylaxis. Increased postoperative complications in patients with bile colonization may render necessary a perioperative antibiotic treatment targeting bile microorganisms. Further prospective studies are needed to improve the anti-infectious strategy in these patients.

Management of pancreatic ascites complicating alcoholic chronic pancreatitis.

INTRODUCTION: Pancreatic ascites (PA) is an unusual and little studied complication of chronic alcoholic pancreatitis. Management is complex and is based mainly on empirical data. The aim of this retrospective work was to analyse the management of PA at our centre. PATIENTS AND METHODS: A total of 24 patients with PA complicating chronic alcoholic pancreatitis were managed at the Lille University Hospital between 2004 and 2018. Treatment was initially medical and then, in case of failure, interventional (endoscopic, radiological and/or surgical). Data regarding epidemiology, therapeutic and follow-up data were collected retrospectively. RESULTS: Twenty-four patients were analysed; median follow-up was 18.5 months [6.75-34.25]. Exclusively medical treatment was effective in three of four patients, but, based on intention to treat, medical therapy alone was effective in only two out of 24 patients. Of 17 patients treated endoscopically, treatment was successful in 15 of them. Of the 15 who underwent surgery, external surgical drainage was effective in 13. Multimodal treatment, initiated after 6.5 days [4-13.5] of medical treatment, was effective in 12 out of 14 patients. In total, 21 patients were successfully treated (87%) with a morbidity rate of 79% and a mortality rate of 12.5% (n=3). CONCLUSION: PA gives rise to significant morbidity and mortality. Conservative medical treatment has only a limited role. If medical treatment fails, endoscopic and then surgical treatment allow a favourable outcome in more than 80% of patients.

Nb and Cu co-doped (La,Sr)(Co,Fe)O3: a stable electrode for solid oxide cells.

Solid oxide cells (SOCs) are electrochemical devices that convert the chemical energy of a fuel into electricity. With regard to electrodes, the development of materials with mixed conduction properties is a key issue for improving the performance of SOCs at high temperatures. New Cu and Nb co-doping La1-x Sr x Fe y Co1-y O3-δ (LSCF) materials were studied as electrode materials on yttria-stabilized zirconia (YSZ) supports. The results show that Cu0.05 + Nb0.05 co-doped LSCF maintains a stable cubic structure even after several heat treatments and has better conductivity than a classically used LSCF.

Distal pancreatectomy with superior mesenteric vein resection without reconstruction for pancreatic neuroendocrine tumor.

Mesenteric and portal vein involvement is seen frequently in pancreatic neoplastic disease and requires venous resection to obtain clear surgical margins. If sufficient collateral circulation is present, venous resection can be performed without reconstruction and without substantial impact on venous drainage.

Genetic findings in miscarriages and their relation to the number of previous miscarriages.

PURPOSE: Early pregnancy loss leads to a devastating situation for many couples. Genetic disorders found in the pregnancy tissue are a frequent cause of miscarriages. It is unclear whether maternal age or previous miscarriages are associated with a higher chromosomal anomaly rate. This study aimed to determine the cytogenetical distribution of chromosomal disorders in couples after one or more previous miscarriages as well as the influence of maternal age. METHODS: 406 fetal tissue samples obtained after spontaneous abortion between 2010 and 2014 were successfully karyotyped. This included 132 couples with at least two losses and 274 couples with sporadic miscarriage. Normal and abnormal karyotype rate was determined for age, parity, gravidity, gestational week and number of previous miscarriages by logistic regression analysis. RESULTS: 145 (35.71%) fetal tissue samples had a normal karyotype, and 261 (64.8%) did not. After adjusting for age, older patients have a statistically significantly higher probability of genetic disorders in the pregnancy tissue (p < 0.001, OR 1.064, 95% CI 1.03-1.11). With each additional year, the probability of finding chromosomal abnormalities in a miscarriage increased by 6.4%. Patients younger than 35 years have a lower probability of having chromosomal disorders in the aborted material after two or more miscarriages than after sporadic miscarriages (50.7 vs. 58.9%) (p = 0.014, OR 0.67, 95% CI 0.48-0.914). Nevertheless, the risk of embryonic chromosomal disorders in patients aged 35 and above increased from 75.5% in sporadic miscarriages to 82.4% after more than one pregnancy losses (p = 0.59, OR 1.14, 95% CI - 0.72 to 1.92). CONCLUSION: Chromosomal disorders found after one or more previous miscarriages are related to patients' age. Couples suffering two or more miscarriages should be further researched, especially in younger patients.

Predictive factors for utilization of a low-volume center in pancreatic surgery: A nationwide study.

STUDY OBJECTIVE: It has been demonstrated that mortality following pancreatectomy is correlated with surgical volume. However, up until now, no French study has focused on predictive factors to undergo pancreatectomy in low-volume centers. The objective of this study is to analyze the clinical characteristics, socio-economic status and medical density according to surgical volume and to analyze predictive factors for undergoing pancreatectomy in low-volume centers. PATIENTS AND METHODS: All patients who underwent pancreatectomy in France from 2012 to 2015 were identified fromthe PMSI database. Hopsitals were classified as low, intermediate and high volume (<10, 11-19, ≥20 resections/year, respectively). Clinical and socioeconomic data, travel distance and rurality were assesed to identify factors associated with undergoing pancreatectomy at low-volume hospitals. RESULTS: In overall, 12,333 patients were included. Those who underwent pancreatectomy in low-volume centers were more likely older, had high Charlson comorbidity index (CCI), had low socioeconomic status, and resided in rural locations.distance traveled by patients operated on in low-volume centers was significantly shorter (23 vs. 61km, P<0.001). In multivariable analysis, older age (P=0.04), CCI≥4 (P=0.008), short travel distance (P<0.001), low socio-economic status (P<0.001) and rurality (P<0.001) were associated withundergoing pancreatectomy in low-volume centers. CONCLUSION: Patients continue to undergo pancreatectomy at low-volume hospitals is due not only to clinical parameters, but also to socioeconomic and environmental factors. These factors should be taken into account in process of pancreatic surgery centralization.

The management of gallbladder polyps.

Neoplastic gallbladder polyps (NGP) are rare; the prevalence in the overall population is less than 10%. NGP are associated with a risk of malignant degeneration and must be distinguished from other benign gallbladder polypoid lesions that occur more frequently. NGP are adenomas and the main risk associated with their management is to fail to detect their progression to gallbladder cancer, which is associated with a particular poor prognosis. The conclusions of the recent European recommendations have a low level of evidence, based essentially on retrospective small-volume studies. Abdominal sonography is the first line study for diagnosis and follow-up for NGP. To prevent the onset of gallbladder cancer, or treat malignant degeneration in its early phases, all NGP larger than 10mm, or symptomatic, or larger than 6mm with associated risk factors for cancer (age over 50, sessile polyp, Indian ethnicity, or patient with primary sclerosing cholangitis) are indications for cholecystectomy. Apart from these situations, simple sonographic surveillance is recommended for at least five years; if the NGP increases in size by more than 2mm in size, cholecystectomy is indicated. Laparoscopic cholecystectomy is possible but if the surgeon feels that the risk of intra-operative gallbladder perforation is high, conversion to laparotomy should be preferred to avoid potential intra-abdominal tumoral dissemination. When malignant NGP is suspected (size greater than 15mm, signs of locoregional extension on imaging), a comprehensive imaging workup should be performed to search for liver extension: in this setting, radical surgery should be considered.

[Risk factors for progression of coronary artery calcification over 5 years in hemodialysis patients]. / Facteurs de risque de progression des calcifications des artères coronaires après 5 ans d'évolution en dialyse.

BACKGROUND: Although progression of coronary artery calcification (CAC) has been established as an important marker for cardiovascular morbidity, very few studies have studied it in end-stage renal disease patients. Thus we examined and evaluate risk factors of calcification changes in dialysis patients. METHOD: Among 28 hemodialysis (HD) patients, CAC was measured in Agatston units at baseline and after five years using the 64 multi-slice ultra-fast CT. The HD patients were classified as progressors or no progressors according to the change in the CAC score across these 2 measurements. RESULTS: Over an average 63 months follow-up, participants without CAC at baseline had no incident CAC. The progression of CAC was slow and was found only in 6 patients (21.4%). It was significantly associated with several cardiovascular risk factors, namely, older age (P=0.03), diabetes (P=0.05), male sex (P=0.02), hypercholesterolemia (P=0.05), anemia (P=0.017), inflammation (P=0.05), and hyperphosphataemia (P=0.012). However, calcemia, parathormone levels, dialysis duration, tobacco, high blood pressure and dialysis dose did not seem to influence the progression of CAC in our series. A strong association was found between basal calcification scores and Delta increment at 5 years. CONCLUSIONS: Our study suggests that CAC progression in dialysis is a complex phenomenon, associated with several risk factors with special regard to elevated basal scores. This progression can be avoided or slowed with appropriate management, which must begin in the early stages of chronic kidney disease.

Impact of cirrhosis in patients undergoing laparoscopic liver resection in a nationwide multicentre survey.

BACKGROUND: The aim was to analyse the impact of cirrhosis on short-term outcomes after laparoscopic liver resection (LLR) in a multicentre national cohort study. METHODS: This retrospective study included all patients undergoing LLR in 27 centres between 2000 and 2017. Cirrhosis was defined as F4 fibrosis on pathological examination. Short-term outcomes of patients with and without liver cirrhosis were compared after propensity score matching by centre volume, demographic and tumour characteristics, and extent of resection. RESULTS: Among 3150 patients included, LLR was performed in 774 patients with (24·6 per cent) and 2376 (75·4 per cent) without cirrhosis. Severe complication and mortality rates in patients with cirrhosis were 10·6 and 2·6 per cent respectively. Posthepatectomy liver failure (PHLF) developed in 3·6 per cent of patients with cirrhosis and was the major cause of death (11 of 20 patients). After matching, patients with cirrhosis tended to have higher rates of severe complications (odds ratio (OR) 1·74, 95 per cent c.i. 0·92 to 3·41; P = 0·096) and PHLF (OR 7·13, 0·91 to 323·10; P = 0·068) than those without cirrhosis. They also had a higher risk of death (OR 5·13, 1·08 to 48·61; P = 0·039). Rates of cardiorespiratory complications (P = 0·338), bile leakage (P = 0·286) and reoperation (P = 0·352) were similar in the two groups. Patients with cirrhosis had a longer hospital stay than those without (11 versus 8 days; P = 0·018). Centre expertise was an independent protective factor against PHLF in patients with cirrhosis (OR 0·33, 0·14 to 0·76; P = 0·010). CONCLUSION: Underlying cirrhosis remains an independent risk factor for impaired outcomes in patients undergoing LLR, even in expert centres.

ANTECEDENTES: El objetivo de este estudio fue analizar el impacto de la cirrosis en los resultados a corto plazo después de la resección hepática laparoscópica (laparoscopic liver resection, LLR) en un estudio de cohortes multicéntrico nacional. MÉTODOS: Este estudio retrospectivo incluyó todos los pacientes sometidos a LLR en 27 centros entre 2000 y 2017. La cirrosis se definió como fibrosis F4 en el examen histopatológico. Los resultados a corto plazo de los pacientes con hígado cirrótico (cirrhotic liver CL) (pacientes CL) y los pacientes con hígado no cirrótico (non-cirrhotic liver, NCL) (pacientes NCL) se compararon después de realizar un emparejamiento por puntaje de propension del volumen del centro, las características demográficas y del tumor, y la extensión de la resección. RESULTADOS: Del total de 3.150 pacientes incluidos, se realizó LLR en 774 (24,6%) pacientes CL y en 2.376 (75,4%) pacientes NCL. Las tasas de complicaciones graves y mortalidad en el grupo de pacientes CL fueron del 10,6% y 2,6%, respectivamente. La insuficiencia hepática posterior a la hepatectomía (post-hepatectomy liver failure, PHLF) fue la principal causa de mortalidad (55% de los casos) y se produjo en el 3,6% de los casos en pacientes CL. Después del emparejamiento, los pacientes CL tendieron a tener tasas más altas de complicaciones graves (razón de oportunidades, odds ratio, OR 1,74; i.c. del 95% 0,92-0,41; P = 0,096) y de PHLF (OR 7,13; i.c. del 95% 0,91-323,10; P = 0,068) en comparación con los pacientes NCL. Los pacientes CL estuvieron expuestos a un mayor riesgo de mortalidad (OR 5,13; i.c. del 95% 1,08-48,6; P = 0,039) en comparación con los pacientes NCL. Los pacientes CL presentaron tasas similares de complicaciones cardiorrespiratorias graves (P = 0,338), de fuga biliar (P = 0,286) y de reintervenciones (P = 0,352) que los pacientes NCL. Los pacientes CL tuvieron una estancia hospitalaria más larga (11 versus 8 días; P = 0,018) que los pacientes NCL. La experiencia del centro fue un factor protector independiente de PHLF (OR 0,33; i.c. del 95% 0,14-0,76; P = 0,010) pacientes CL. CONCLUSIÓN: La presencia de cirrosis subyacente sigue siendo un factor de riesgo independiente de peores resultados en pacientes sometidos a resección hepática laparoscópica, incluso en centros con experiencia.

[Isolated diastolic hypotension in hemodialysis: Risk factor for novel cardiovascular complications and all-cause mortality]. / L'hypotension diastolique isolée en hémodialyse : facteur de risque de complications cardiovasculaires de novo et de mortalité toute cause.

Intra dialytic hypotension is the most common complication in hemodialysis. However, isolated diastolic hypotension (IDH) in hemodialysis is asymptomatic and its detection requires repeated monitoring of blood pressure during dialysis sessions. To study this phenomenon, we conducted a prospective study over a period of 5 years in 45 chronic hemodialysis patients. The IDH, was noted in 42% at inclusion, and in 59,5% of the cases at the end of the study. IDH was associated with advanced age, female gender, high relative critical blood volume, cardiac arrhythmias and diastolic dysfunction of the left ventricle. IDH was also significantly associated with novel cardiovascular complications (P=0.004) and all-cause mortality (P=0.038). Isolated diastolic hypotension is a particularly common phenomenon in hemodialysis. Our data encourage in-depth reflection on this subject in hemodialysis. In addition, our study highlights the value of screening for IDH by close monitoring of hemodynamic parameters, and calls for personalized dialysis management based on the analysis of the demonstrated risk factors and on the study of the associated comorbidities.

Do complications following pancreatic resections impact hospital costs in France: Medico-economic study on 127 patients.

OBJECTIVE: To define the cost of pancreatectomies and to identify factors associated with increased hospital costs after pancreatic resection. METHODS: All patients undergoing pancreatic surgery in our department between January 2008 and December 2014 were included. All complications occurring during hospitalization or in the 90-day period after discharge were documented. The hospital costs were analyzed and predictive factors of increased hospital costs were determined. RESULTS: One hundred and twenty seven patients were identified. Most patients underwent pancreatectomy for malignant tumors (70%). Median hospital costs were 21,392 [15,998-29,667] euros. Age (P=0.011) and preoperative jaundice (P<0.001) were associated with higher hospital costs. Intraoperative surgical time and blood loss were correlated with increased costs (P=0.001 and P=0.002, respectively). Pancreatoduodenectomy was associated with statistically significantly higher costs compared to distal pancreatectomy (21,770 vs. 15,422 euros, P=0.001). Severe postoperative complications (Clavien-Dindo grade≥3) (P=0.001), septic complications (P=0.002) and hemorrhage (P=0.001) statistically significantly increased costs. In multivariate analysis, septic (P=0.003) and severe complications (P=0.01) were statistically significantly associated with increased hospital costs. CONCLUSION: Pancreatic surgery is associated with high hospital costs, essentially related to postoperative complications.

Leucémie aigue lymphoblastique néonatale : À propos d'un cas au CHU Hassan II de Fès au Maroc

La leucémie aiguë lymphoblastique (LAL) néonatale est une affection exceptionnelle et est de mauvais pronostic. Nous décrivons l'observation d'un nouveau-né à Jo de vie, atteint d'une LAL de type B, révélée par un syndrome hémorragique et tumoral en service de réanimation néonatale du CHU Hassan II de Fès, dont l'évolution a été marqué après 25 jours de vie par le décès du patient dans un tableau de lyse tumoral, quelques jours après une chimiothérapie d'induction

Membranoproliferative Glomerulonephritis Associated with a Human Immunodeficiency Virus Infection.

Type 1 membranoproliferative glomerulonephritis (MPGN) is an uncommon manifestation of human immunodeficiency virus (HIV)-associated renal disease in patients coinfected with hepatitis C virus. We report a case of MPGN characterized by nephrotic syndrome associated with HIV without hepatitis C coinfection. The patient had a favorable response to highly active antiretroviral therapy and angiotensin-converting enzyme inhibitors. Recognition of the MPGN lesion in HIV infection devoid of hepatitis C coinfection must be considered.

La main de presse: une brûlure pas comme les autres.

Burns to the upper limb caused by contact with a hot press are associated with a compression trauma of variable severity. These burns are rare, and they mostly occur in the context of accidents at work due to mishandling. They can cause severe multi-tissue injuries requiring urgent multidisciplinary care. Their psycho-social repercussions are considerable, especially as they affect a young population.

Tuberculosis in hemodialysis.

Chronic uremia puts patients at increased risk of infectious complications, in particular, tuberculosis. In this prospective study, we analyzed the clinical, paraclinical, and therapeutic features as well as outcome for all patients on chronic hemodialysis with tuberculosis from January 2010 through August 2012. Sixty-one patients were admitted for bacterial infections, 23% of them for tuberculosis. Fever was present in 71% of cases, and CRP elevated in all cases. The tuberculin skin test was positive in only 2 of 9 cases, and Mycobacterium tuberculosis isolated in 2 of 10 cases. Histological evidence was obtained in 7 of 9 cases. Plain radiographs and computed tomography evoked tuberculosis. The location was extrapulmonary in 71% of cases. Chemotherapy for tuberculosis was based on a quadruple therapy for 10 patients and triple therapy for 3. The outcome was favorable in 11 patients and fatal for 3. Tuberculosis is much more common in hemodialysis patients than in the general population. The telltale signs are nonspecific. Prognosis is closely linked to early diagnosis and treatment.

Evaluation of a novel multiplex RT-qPCR assay for the quantification of leukemia-associated BCR-ABL1 translocation.

Although monitoring of BCR-ABL1 translocation has become an established practice in the management of chronic myeloid leukemia (CML), the detection limit of the BCR-ABL1 transcripts needs more standardization. The aim of the present study was to evaluate the clinical performances of a novel assay for the quantification of BCR-ABL1 fusion transcripts (e13a2 and e14a2) and ABL1 in a single reaction. This assay is based on the real-time reverse transcription polymerase chain reaction (RT-qPCR) in multiplex format. In a retrospective comparative clinical study performed in a reference laboratory, RNA was extracted from 48 CML patient blood samples with various BCR-ABL1/ABL1 ratios and RT-qPCR was performed using either MAScIR assay or the RT-qPCR simplex reference assay used in routine clinical testing. The comparative clinical results showed high qualitative and quantitative concordance (correlation coefficient >0.95) between MAScIR and the reference assays. The present study illustrates the utility of MAScIR assay as a sensitive, rapid, and cost-effective quantitative device to monitor the BCR-ABL1 ratios by RT-qPCR on whole blood of diagnosed Philadelphia chromosome-positive (Ph+) leukemia patients. This test could be used as an aid in the assessment of molecular response to available treatments.

Quantitative real-time polymerase chain reaction as an efficient molecular tool for detecting minimal residual disease in Moroccan chronic myeloid leukemia patients.

Chronic myeloid leukemia (CML) is characterized by BCR-ABL translocation and an increased number and migration of immature myeloid cells into the peripheral blood. The detection limit of the BCR-ABL transcript, particularly after treatment, is controversial. In the present study, we used quantitative real-time reverse transcription-polymerase chain reaction (RT-qPCR) to monitor BCR-ABL expression in Moroccan CML patients undergoing imatinib treatment, and compared the results with those of conventional PCR and fluorescence in situ hybridization (FISH). The aim of this study was to establish a new molecular tool for in vitro diagnosis of CML. In a retrospective comparative analysis, 20 CML Moroccan patients who had received imatinib treatment (N = 20) were analyzed by real-time PCR, conventional RT-PCR, and FISH. Half of the samples analyzed (N = 10) were positive for BCR-ABL gene expression, while the other half (N = 10) were negative according to conventional PCR. Interestingly, 5 of the 10 samples shown to be negative by conventional PCR showed positive expression of the BCR-ABL gene according to RT-qPCR. The RT-qPCR results were confirmed by FISH, which revealed a high concordance (100%) rate. We found that real-time RT-qPCR is more reliable and should be used in Moroccan biomedical analysis laboratories to monitor CML progression, particularly for minimal residual disease, following imatinib treatment.
