RESUMEN

Members of the eukaryotic translation initiation complex are co-opted in viral infection, leading to susceptibility in many crop species, including stone fruit trees (Prunus spp.). Therefore, modification of one of those eukaryotic translation initiation factors or changes in their gene expression may result in resistance. We searched the crop and wild Prunus germplasm from the Armeniaca and Amygdalus taxonomic sections for allelic variants in the eIF4E and eIFiso4E genes, to identify alleles potentially linked to resistance to Plum pox virus (PPV). Over one thousand stone fruit accessions (1397) were screened for variation in eIF4E and eIFiso4E transcript sequences which are in single copy within the diploid Prunus genome. We identified new alleles for both genes differing from haplotypes associated with PPV susceptible accessions. Overall, analyses showed that eIFiso4E is genetically more constrained since it displayed less polymorphism than eIF4E. We also demonstrated more variations at both loci in the related wild species than in crop species. As the eIFiso4E translation initiation factor was identified as indispensable for PPV infection, a selection of ten different eIFiso4E haplotypes along 13 accessions were tested by infection with PPV and eight of them displayed a range of reduced susceptibility to resistance, indicating new potential sources of resistance to sharka.

RESUMEN

The aim of this study was to evaluate the outcome of ulnar superficialis slip resection and to determine predictive factors for poor prognosis in patients with advanced trigger finger. Over a 5-year-period, 55 patients (58 fingers) were included. After surgery, two groups were identified: group 1, with complete extension or <10° extension deficit in the proximal interphalangeal (PIP) joint (n = 27 fingers/27 patients); and group 2, with ≥10° residual PIP extension deficit (n = 31 fingers/28 patients). Factors associated with PIP extension deficit were assessed on logistic regression. There was a median extension gain of 20° (range, 10-30°) after surgery. The difference between pre- and post-operative extension deficits was significant (p < 0.001). There was no significant inter-group difference in DASH score (p > 0.9). Two predictive factors were found: >12 months' preoperative symptom duration (OR = 1.02; p = 0.045), and lack of self-rehabilitation (OR = 20; p < 0.001). Ulnar superficialis slip resection was effective in advanced trigger finger. Hand surgeons should operate early on these patients, and encourage self-rehabilitation. LEVEL OF EVIDENCE: 4.

RESUMEN

Urethro-rectal fistula (URF) is a rare but serious condition whose treatment is poorly codified. This study aims to evaluate the short and long-term results of multidisciplinary management. MATERIAL AND METHODS: We retrospectively collected the records of patients with URF operated on at the University Hospital of Tours between January 1, 2000 and January 1, 2020. Short-term and long-term results according to management are reported. RESULTS: The study included 20 patients. As an initial gesture, 11 patients underwent bladder catheterization and colostomy, seven underwent bladder catheterization alone, one underwent graciloplasty, and one, a York Mason procedure. The success rate of initial conservative management was only 5% (1/20). As a secondary or tertiary intervention, ten patients underwent a York Mason procedure and nine underwent graciloplasty. At the end of the study period, with a median follow-up of 50 months, 19 had been effectively treated for URF, 16 were able to have colostomy closure with restoration of digestive continuity while four had a permanent stoma. One patient had anal incontinence, 14% had major stress urinary incontinence. CONCLUSION: Multidisciplinary care remains a cornerstone of the treatment of URF because iterative surgeries may be required, with an overall success rate of up to 95% at the end of follow-up.

RESUMEN

Endoscopic procedures such as ureteroscopy (URS) have seen a recent increase in single-use devices. Despite all the advantages provided by disposable ureteroscopes (sURSs), their cost effectiveness remains questionable, leading most teams to use a hybrid strategy combining reusable (rURS) and disposable devices. Our study aimed to create an economic model that estimated the cut-off value of rURS procedures needed to support the profitability of a hybrid strategy (HS) for ureteroscopy. We used a budget impact analysis (BIA) model that estimated the financial impact of an HS compared to 100% sURS use. The model included hospital volume, sterilization costs and the private or public status of the institution. Although the hybrid strategy generally remains the best economic and clinical option, a predictive BIA model is recommended for the decision-making. We found that the minimal optimal proportion of rURS procedures in an HS was mainly impacted by the activity volume and overall number of sterilization procedures. Private and public institutions must consider these variables and models in order to adapt their HS and remain profitable.

RESUMEN

OBJECTIVE: The aim of this study was to examine the influence of a median lobe (ML) on complications and functional results after 4 years of GreenLight photoselective vaporization of the prostate (PVP). METHODS: All men undergoing GreenLight PVP for benign prostatic hyperplasia were included in the baseline analysis and followed prospectively. Two groups were formed according to the presence or absence of the prostatic ML. Complications classified according Clavien and Dindo and functional results (International Prostate Symptom Score [IPSS], quality of life, maximum urinary flow rate [Qmax], and postvoid residual [PVR]) were evaluated with 4 years of follow-up. The pre- and postoperative data were compared by a chi-square test (χ2 ) for the qualitative variables and by a Student t test for the quantitative variables. RESULTS: A total of 432 patients (172 with ML and 260 without ML) were included prospectively from September 2005 to October 2013. The initial populations were comparable. At 4 years of follow-up, the improvement in mean IPSS was significantly greater for patients with ML at 6, 12, 24, and 48 months. The improvement in Qmax was significantly greater for patients with ML at 1, 6, 24, and 48 months. There was no significant difference between the two groups concerning the PVR reduction, the occurrence of complications, the level of average prostate-specific antigen, and the average ultrasound volume at 4 years. CONCLUSION: There is a clearer and longer-lasting improvement in urinary symptoms in patients with prostatic ML. The indication of PVP in those patients seems to be excellent, with good results persisting at 4 years.

RESUMEN

INTRODUCTION: The shortage of kidney transplants encourages the expansion of the limits of eligibility criteria for donation. Many donors who are brain dead display acute renal failure at the time of death; is this a real contraindication to harvesting? The aim of this study was to assess kidney graft survival from donors after brain death with confirmed acute renal failure, with or without anuria previous donation. MATERIALS AND METHODS: All of the transplants performed in two university hospitals between 2010 and 2017 were analyzed retrospectively. All patients who underwent single kidney transplant from a brain-dead donor with acute renal failure (ARF) were included in this study. ARI was defined here by a decrease over 50 % of glomerular filtration rate (GFR) to a threshold below 45mL/min/1.73 m2 at the time of kidney procurement. Kidney graft survival, incidence of delayed graft function (DGF) and the GFR at 12 months were analyzed. Analysis of kidney transplant survival based on pre-implantation biopsies was additionally done. RESULTS: One hundred and sixty four patients were transplanted with a kidney from donor with ARF during the selected period. At the admission in ICU the average GFR was 67,7±19mL/min/1,73m2. At the time of donation, the average age of donors was 56.4±17.7 years, the GFR was 33.7±8.0mL/min/1.73 m2 16 % of donors were anuric. Cold ischemia time (CIT) was 16.8±5.0hours. The average age of recipients was 55.6±14.1 years. 81 % of the cases were primary transplants. Graft function took place within 7.8±9.4 days after transplantation. There were two non-primary functions (PNF). One hundred and fifty two patients (93 %) had a functional graft at 12 months. The mean GFR at 12 months was 46.8±20.1mL/min/1.73 m2 and 122 patients (73 %) had a GFR greater than 30mL/min/1.73 m2. Seventy-one percent of preimplantation biopsies revealed acute tubular necrosis (ATU); no cortical necrosis was observed. Survival of theses grafts was 85 %, comparable to the total population of study (P=0,21) CONCLUSION: The acute renal failure of the brain-dead donor should not alone be systematically a contraindication to harvesting and kidney transplantation.

RESUMEN

OBJECTIVES: To assess the financial impact of switching to single-use ureteroscopes (sURS) in urolithiasis management for a hospital, over a 5-year period, and to identify possible solutions to contain or reduce it. METHODS: A Budget Impact (BI) model was designed for a public hospital performing around 200 ureteroscopies or extracorporeal shockwave lithotripsies per year. The BI was estimated as the difference between financial balances (between costs and revenues) of 2 environments (with and without sURS). The population was defined as adults treated for urolithiasis. The BI model was based on assumptions about the expected progression in the incidence of urolithiasis, and the expected change in clinical practices due to the availability of sURS. We considered the costs and revenues of hospital stays, the purchase price of sURS and the costs of digital or fiberoptic reusable ureteroscopes (rURS). Univariate and multivariate sensitivity analyses were performed. RESULTS: The cumulative 5-year financial impact of switching completely to sURS was €807,824 and €649,677 in comparison with fiberoptic and digital rURS respectively. This impact could be reduced by half or more if the health-care facility were to adopt different solutions, including negotiating the purchase price of sURS, developing outpatient activity and reducing production costs for ureteroscopy procedures. CONCLUSION: The BI model gives decision-makers a more accurate picture of the financial impact of switching to sURS and highlights ways to reduce the expected additional cost.

RESUMEN

The aim of this study was to assess the clinical and radiographic outcomes after radioscapholunate (RSL) fusion for posttraumatic osteoarthritis. This was a retrospective, dual-center study of all patients who underwent RSL fusion between 1995 and 2015 for posttraumatic radiocarpal osteoarthritis. Patients were assessed at the final review to determine clinical (pain, wrist range of motion and strength), self-reported (QuickDASH, PRWE and MWS scores) and radiological (degenerative osteoarthritis in the scaphotrapeziotrapezoid (STT) or midcarpal joint and radiocarpal fusion) outcomes. We analyzed three groups: RSL fusion alone, RSL fusion with distal scaphoid excision (DSE) and RSL fusion with DSE and triquetrum excision (TE). Eighty-five patients were included; 10 were lost to follow-up and 11 required conversion to total wrist fusion before the final review. Finally, 64 patients had both clinical and radiographic evaluations. The mean follow-up was 9.1 years (range 1-21.4). RSL fusion alone was performed in 29 patients, RSL fusion with DSE in 23 and RSL fusion with DSE and TE in 12. At the final follow-up, the three groups did not differ in their pain or wrist motion. Overall, 47 (73%) patients were satisfied or very satisfied with the procedure. DSE significantly decreased STT osteoarthritis and radiocarpal non-union. The total wrist osteoarthritis rate after RSL fusion was 55%. RSL fusion is an effective procedure to preserve some motion in wrists with posttraumatic radiocarpal osteoarthritis. DSE prevents STT osteoarthritis by removing bony impingement and increases the fusion rate. LEVEL OF EVIDENCE: Level IV, Case series, Therapeutic studies.

RESUMEN

Skin envelope degloving of fingers are rare injuries that require rapid care and surgical treatment. Mostly caused by ring finger injuries, these traumas include bone, tendon and neurovascular pedicle damage. The authors present an unusual case of finger degloving limited exclusively to the skin envelope, without skeletal, tendinous or vascular lesion. This rare case of skin envelope degloving rendered microsurgical revascularization impossible. The authors report the results at 12 months following salvage reconstruction combining a partial second toe pulp free flap for the volar side and a dermal substitute with a thin skin graft for the dorsum.

RESUMEN

OBJECTIVES: To describe the technique and report our first experience of robotic-assisted renal transplantation (RART) with more than one year follow up. PATIENTS AND METHODS: In our center the first case of RART was realized in October 2013 with a cadaveric graft. We used the combined extra- and intraperitoneal robot assisted laparoscopic route with extraperitoneal positioning of the graft and intraperitoneal transplantation. The patient was placed in the supine position with arms along the body; the robot came from the right inferior part of the patient. Access to the retroperitoneal space was obtained using an Alexis trocar that permitted the insertion of the kidney with ice without losing the pneumoperitoneum. Ports included a 12-mm camera port (placed under the ombilicus), two 8-mm robotic ports (placed 6cms laterally from the previous port) and a 12-mm assistant port (placed between the upper port and the ombilic). All the pre-, per- and postoperative data were prospectively included in a database. We report the results of the initial experience of RART, performed with more than one year follow-up. RESULTS: This technique is the first described using the retroperitoneal approach that is the routine approach for conventional open renal transplantation. This approach permitted to perform excellent arterial, veinous and ureteral anastomosis. Eight cases of RART were conducted between October 2013 and November 2015 (five men and three women). The average age was 58 years (range 39-75years). The average body mass index was 28 (range 22-38). Five patients had history of abdominal surgery and were dialyzed for 30 months on average (range 3-63months). Three left and five right cadavers kidneys were transplanted in the right iliac fossa. The mean graft size was 109mm (range 90-130). The mean length of the incision for insertion of the graft was 60 mms (40-100mms). Mean warm ischemia time was 63minutes (range 46-84). The total operative time was 200minutes (149-245). No patient was transfused during surgery and two were transfused postoperatively. Median length of hospital stay was 14 days (range 10-30 days). Only one patient needed postoperative morphine, the pain visual analogic scale 12hours postoperatively was 2 (0-5). Mean serum creatinine at seven days, at three months and at one year was 400 (98-639micromol/L), 151 (80-235micromol/L) and 129 (86-194micromol/L) respectively. At one year follow-up, no patient had a wound infection or incisional hernia. One patient was re-operated for ureteral anastomosis stricture. CONCLUSION: The retroperitoneal approach for RART permits the kidney to be cooled and a direct access to the iliac vessels and bladder. This initial series with more than a year of post-monitoring RART shows promising results despite some initial technical difficulties. The procedure can still be improved and hoped to see an improvement in the results. A comparison to the results of the conventional route is necessary before diffusing the robot-assisted technique. LEVEL OF PROOF: 3.

RESUMEN

INTRODUCTION: Radioscapholunate (RSL) fusion is typically performed following wrist trauma. It addresses the pain caused by radiocarpal osteoarthritis but reduces the wrist's mobility. The objective of this study was to determine the long-term clinical and radiological outcomes of this procedure. MATERIALS AND METHODS: This was a retrospective study of all wrists operated for RSL fusion in our surgery unit over a 12-year period. The clinical analysis consisted of joint amplitudes, grip strength, pain (VAS) and functional scores (PRWE, QuickDash, Mayo Wrist Score). The radiological analysis focused on bone fusion and the presence of midcarpal osteoarthritis. RESULTS: This surgery procedure was performed on 48 wrists. Of these, 34 patients were available for review, including 6 who had subsequently undergone total wrist fusion after the RSL procedure. The average follow-up was 53 months. Flexion/extension and radioulnar deviation were 56° and 30°, respectively. Grip strength in the operated wrist was 71% of the contralateral wrist. The mean pain level was 3 out of 10. The PRWE, QuickDash and Mayo Wrist Score were 35.7, 44.5 and 57.2, respectively. Seventy-nine percent of patients were satisfied with the outcome. The fusion rate was 71%, the midcarpal osteoarthritis rate was 64% and the STT osteoarthritis rate was 46%. DISCUSSION: Reduced wrist range of motion in patients who have undergone RSL fusion helps to preserve satisfactory function in the majority of patients; however, the functional outcome scores point to some hindrance in day-to-day activities. Nonunion occurred in nearly one-quarter of patients and appears to be preventable by excision of the distal pole of the scaphoid (DPS). Midcarpal osteoarthritis develops in most wrists over the long-term and appears to be inevitable. CONCLUSION: RSL fusion is a palliative procedure that preserves some of the wrist's mobility. However, it is a difficult procedure that has a significant nonunion rate. Excision of the DPS may contribute to lowering the nonunion rate.

RESUMEN

Emergency arthroplasty of the metacarpophalangeal joint (MCPJ) remains a valuable treatment option in patients with MCPJ destruction but may raise challenges in the event of substantial metacarpal and/or phalangeal bone defects. We report three cases of MCPJ destruction with bone defects at the proximal first phalanx treated with emergency silicone implant arthroplasty combined with bone grafting.

RESUMEN

The coverage of soft-tissue defects concerning the front of the knee and the proximal lower leg is a complex procedure. The reverse flow anterolateral thigh flap represents a good solution for this defects, especially when the coverage surface is large-sized and a free flap is not appropriate regarding the difficulty of the process. Flap retrograde vascularization is based on the anastomosis between the descending branch of the circumflex femoral artery and lateral superior genicular artery. It is an easy solution with low morbidity. The authors have chosen this flap to cover soft-tissue defect of anterior knee from two patients with total knee prothesis.

RESUMEN

Persistent ATG-induced CD4(+) T cell lymphopenia is associated with serious clinical complications. We tested the hypothesis that ATG induces accelerated immune senescence in renal transplant recipients (RTR). Immune senescence biomarkers were analyzed at transplant and one-year later in 97 incident RTR -62 patients receiving ATG and 35 receiving anti-CD25 mAb (α-CD25). This consisted in: (i) thymic output; (ii) bone marrow renewal of CD34(+) hematopoietic progenitor cells (CD34(+) HPC) and lymphoid (l-HPC) and myeloid (m-HPC) progenitor ratio; (iii) T cell phenotype; and (iv) measurement of T cell relative telomere length (RTL) and telomerase activity (RTA). Clinical correlates were analyzed with a 3 year follow-up. Thymic output significantly decreased one-year posttransplant in ATG-treated patients. ATG was associated with a significant decrease in l-HPC/m-HPC ratio. Late stage differentiated CD57(+) /CD28(-) T cells increased in ATG-treated patients. One-year posttransplant T cell RTL and RTA were consequently lower in ATG-treated patients. ATG is associated with accelerated immune senescence. Increased frequency of late differentiated CD4(+) T cell frequency at transplantation tended to be predictive of a higher risk of subsequent opportunistic infections and of acute rejection only in ATG-treated patients but this needs confirmation. Considering pretransplant immune profile may help to select those patients who may benefit from ATG to prevent severe infections and acute rejection.

RESUMEN

Confocal Raman microspectroscopy and fluorescence imaging are two well-established methods providing functional insight into the extracellular matrix and into living cells and tissues, respectively, down to single molecule detection. In living tissues, however, cells and extracellular matrix coexist and interact. To acquire information on this cell-matrix interaction, we developed a technique for colocalized, correlative multispectral tissue analysis by implementing high-sensitivity, wide-field fluorescence imaging on a confocal Raman microscope. As a proof of principle, we study early stages of bone formation in the zebrafish (Danio rerio) larvae because the zebrafish has emerged as a model organism to study vertebrate development. The newly formed bones were stained using a calcium fluorescent marker and the maturation process was imaged and chemically characterized in vivo. Results obtained from early stages of mineral deposition in the zebrafish fin bone unequivocally show the presence of hydrogen phosphate containing mineral phases in addition to the carbonated apatite mineral. The approach developed here opens significant opportunities in molecular imaging of metabolic activities, intracellular sensing, and trafficking as well as in vivo exploration of cell-tissue interfaces under (patho-)physiological conditions.

RESUMEN

UNLABELLED: What's known on the subject? and What does the study add? Urinary incontinence is one of the major drawbacks of radical prostatectomy, regardless of the procedure used (i.e. open, laparoscopic or robotic-assisted). Several technical modifications have been described to improve postoperative continence, highlighting the role of puboprostatic ligaments and posterior reconstruction of the rhabdomyosphincter. The results obtained are inconsistent when applied to robotic surgery. The present multicentre randomized study shows that anterior suspension combined with posterior reconstruction is a safe and easy-to-perform technique for improving early continence after robotic-assisted laparoscopic prostatectomy. OBJECTIVE: To assess the impact on urinary continence of anterior retropubic suspension with posterior reconstruction during robot-assisted laparoscopic prostatectomy (RALP). PATIENTS AND METHODS: In total, 72 patients who were due to undergo prostatectomy between July 2009 and July 2010 were prospectively randomized into two groups: group A underwent a standard RALP procedure and group B had anterior suspension and posterior reconstruction during RALP. The primary outcome measure was urinary continence, assessed using the University of California Los Angeles Prostate Cancer Index questionnaire at 15 days, and at 1, 3 and 6 months, after surgery. Other data recorded were operation duration, blood loss, length of hospital stay, duration of bladder catheterization, complications and positive margin rate. RESULTS: The continence rates at 15 days, and at 1, 3 and 6 months, after surgery were 3.6%, 7.1%, 15.4% and 57.9%, respectively, in group A, and 5.9%, 26.5%, 45.2% and 65.4%, respectively, in group B. The continence rates differed statistically between groups at 1 and 3 months (P = 0.047 and P = 0.016, respectively). There was no significant difference between groups regarding complications (P = 0.8) or positive margin rate (P = 0.46). CONCLUSION: Anterior suspension associated with posterior reconstruction during RALP improved the early return of continence, without increasing complications.
