RESUMEN

INTRODUCTION: Medication reconciliation at hospital and the shared medication review are two complementary activities for securing the medication management of the elderly patient. We are experimenting with a pharmaceutical care pathway including a support approach to promote continuity between these two activities and the initiation of shared medication review. MATERIALS AND METHODS: An admission and discharge medication reconciliation has been set up in a geriatric follow-up care and rehabilitation service. A drug assessment was also carried out during the hospital stay. Support for community pharmacists following conciliation was provided by phone calls. Medication discrepancies at admission and discharge, pharmaceutical interventions (PI) as well as satisfaction and difficulties encountered by community pharmacists were collected. RESULTS: Thirty-three patients were included in the study. On admission, 33% of patients had an unintentional discrepancy and 15% on discharge. On average 1.15 PI per patient were notified. The support was propounded to 13 pharmacists. Eight pharmacists (62%) accepted it. Among them, 5 (62.5%) had never performed a medication review. Lack of time was the main difficulty encountered by pharmacists. DISCUSSION AND CONCLUSION: Our pathway enables to integrate hospital and primary care activities and specifically support the delicate transition between them. This enables to facilitate the implementation of these activities and to maintain a relevant and secure continuity of pharmaceutical care.

RESUMEN

OBJECTIVE: To examine the impact of positive surgical margins (PSM) after radical prostatectomy (RP) for prostate cancer on oncological results. PATIENTS AND METHODS: We performed a study where all patients who underwent radical prostatectomy between January 2004 and December 2018 for prostate cancer were included. The preoperative, postoperative data and the carcinological results collected were analyzed. Data were analysed using Kaplan-Meier survival analysis and proportional hazards models. RESULTS: A total of 319 patients with a median age of 65 years (IQR : 62-69) were included. The median follow-up was 43.6 months (IQR: 19.4-79.3). The overall rate of PSM was 33.5%. PSM was associated with biochemical recurrence (P<0.001). Overall mortality was not associated with positive margins. A clinical stage> T1c was an independent predictor of PSM on multivariate analysis (P=0.01). CONCLUSION: PSM would increase the risk of biochemical recurrence with no impact on survival. Clinical stage>T1c was an adverse predictor for PSM. LEVEL OF EVIDENCE: 3.

RESUMEN

INTRODUCTION: We aimed to assess the impact of antiplatelet and anticoagulation therapy for patients undergoing HoLEP. METHODS: We performed a study during the learning curve on a consecutive series of patients who underwent HoLEP surgery from 2015 to 2018. The patients were divided into 3 groups: a control group, patients with antiplatelet therapy and patients with anticoagulation therapy. RESULTS: A total of 223 patients underwent HoLEP surgery during this period: 124 in the control group, 63 in the antiplatelet group and 36 in the anticoagulant group. In the anticoagulant group, we observe significant differences with the control group for the catheterization time (2.05 days vs 5.17 days; P<0.001), the hospital length of stay (1.5 nights vs 4.49 nights; P<0.001) and complications (8.9% vs 58%; P<0.001). No difference between the control and antiplatelet groups in terms of catheterization time, hospital length of stay and complications (2.05 days vs 2.68 days; 1.5 nights vs 1.6 nights) but variation in terms of complications and bleeding complications (8.9% vs 21%; P<0,001; 8.1% vs 19%; P<0,001) CONCLUSION: Our study shows that HoLEP is therefore associated with a higher risk of bleeding for patients treated with anticoagulation therapy. Complications increase morbidity with longer catheterization time, hospitalization times and higher transfusion's rates, revision surgery and readmission. LEVEL OF EVIDENCE: 3.

RESUMEN

INTRODUCTION: Military people are inapt for presence of urinary stones. In this specific population, the treatment of stones is even more aggressive than for the general population without recommendation. The final decision about aptitude is the responsibility of the military doctor. Whereas, ureteroscopy has its place there and must done by any urologist. METHODS: The purpose of this study was to estimate the results of treatments by ureteroscopy in this population. Success was defined by the complete absence of fragment visualized in the imaging of control operating comment and so the end of the inaptitude time. RESULTS: Between 2009 and 2016, forty-two were treated for ureteral or renal calculi. The population comprises of 93% men, 35 years old on average. The stones were mainly multiple (more 2) and the medium size is 5mm; sixteen (42.9%) was at the left and eight (19%) was bilateral. In 78.8% (78) of the cases there was a stone in renal position whose 50% (39) still at the lower calyx. In total, 5% of the patients were stone-free in 2 sessions on average. The average deadline of inaptitude of the initial consultation in the resumption of work was of 6 months. In 4% of the cases there was a complication operating rank 4. CONCLUSION: This study confirms the feasibility, the weak harmlessness of ureteroscopy and the lesser deadline of inaptitude. Every urologist can treat this specific population. The patient must be informed and accept the treatment because of excluding referential. LEVEL OF EVIDENCE: 4.

RESUMEN

PURPOSE: To report oncological outcomes of patients with prostate cancer undergoing active surveillance according to SURACAP criteria. METHODS: This multicentric study included patients who were initially treated with active surveillance for localized prostate cancer according to the SURACAP criteria. The duration of active surveillance as well as the causes of discontinuing the protocol and the definitive pathological results of patients who further underwent radical prostatectomy were retrospectively evaluated. The predictors of discontinuing active surveillance were assessed using a univariable Cox Model. In addition, the predictive value of initial MRI was assessed for patients who performed such imagery. RESULTS: Between 2007 and 2013, 80 patients were included, with a median age of 64 years [47-74]. Median follow-up was 52.9 months [24-108]. At 5 years follow-up, 43.4% patients were still under surveillance. Among patients that underwent surgery, 17.8% had an extra-capsular extension. The risk of discontinuing was not significantly greater for patients with tumor size of 2 or 3mm versus 1mm (HR=0.9 [0.46-1.75], P=0.763), 2 positives cores versus 1 (HR=0.98 [0.48-2.02], P=0.967), T2a vs. T1c stage (HR=2.18 [0.77-6.18], P=0.133), increased PSA level (HR=1 [0.96-1.15], P=0.975) or the patient's age (HR=1 [0.93-1.16], P=0.966). Among the 50 patients who performed initial MRI, the results of such imagery was not significantly associated to the risk of discontinuing active surveillance MRI (HR=1.49 [0.63-3.52], P=0.36). CONCLUSION: Although this study reveals a high rate of release from active surveillance at 5 years, the rate of extra-capsular tumors reported in the group of patients that underwent surgery is among the lowest in literature. LEVEL OF EVIDENCE: 4.

RESUMEN

INTRODUCTION: Kidney transplantation is the most suitable of ESRD care. The proportion of obese people is increasing in the general population and patients with kidney impairment. It is important to assess the impact of obesity on surgical complications of kidney transplantation. The aim of this retrospective study was to signify the correlation between obesity and the occurrence of postoperative urological complications during the first year. METHODS: We conducted a retrospective study from March 1999 to December 2009. We conducted a chart review of patients undergoing kidney transplantation. The kidneys were taken from cadaveric donors. Data collected included age, weight, height, preoperative BMI; causal nephropathy, smoking, hypertension, diabetes, anticoagulation therapy. Intraoperative data included operative time (DO), cold ischemia. Urological complications were recorded during the first year after the kidney transplantation (vascular anastomotic strictures, ureterovesical stenosis, lymphorrheas, pyelonephritis, hematoma, wound infection). Statistical analysis consisted of a t-test for independent samples and univariate and multivariate logistic regression for the occurrence of complications. RESULTS: Four hundred and twenty-two patients were transplanted in total. We excluded 20 patients. BMI and duration of surgery patients with complications were significantly different from those of patients with no complications (P=0.016 and P=0.039, respectively). Obese (n=48) had more diabetes (12.5% versus 3.7%, P=0.014), were more often smoking (35.4% versus 22%, P=0.012), had a longer DO (203.64minutes versus 182.46minutes, P=0.006), and complications (62.5% versus 50.28%, P=0.03) than patients with a BMI <30 (n=354). After adjusting for age, smoking, DO, diabetes and BMI showed that only BMI was an independent predictor of the occurrence of postoperative complications with P=0.048 and RR=1.058 [CI: 1 to 1.119]. However, there was no more transplantectomy obese (P=0.911). CONCLUSION: Our study showed that there is a significant risk of surgical complications after kidney transplantation in obese patients. But ultimately, this does not affect graft survival because there are no more transplantectomies or return to dialysis. LEVEL OF EVIDENCE: 5.

RESUMEN

INTRODUCTION: Kidney transplantation is the treatment of choice for ESRD. Several studies have investigated the factors that may affect kidney function at 1 year. The factors mentioned are anemia, hypercholesterolemia, immunosuppressors, etc. We studied the independent predictors of serum creatinine>100µmol/L at 1 year. MATERIALS AND METHODS: We conducted a retrospective study from March 1999 to December 2009. We conducted a chart review of 402 kidney transplant patients. The kidneys were removed from cadaveric donors. Data collected included age, weight, height, preoperative BMI, the causal nephropathy, smoking, hypertension, diabetes, anticoagulation. Intraoperative data included operative time, and cold ischemia. Statistical analysis consisted of a t-test for independent samples comparing the group with a creatinine≤100µmol/L vs>100 group, and univariate and multivariate Cox regression for a serum creatinine>100µmol/L at 1 year and test of correlation between BMI and serum creatinine at 1 year postoperatively. RESULTS: We found a significant difference in BMI and cold ischemia with P=0.008 and P=0.002, respectively. In contrast there was no difference in age, operative time and blood loss, P=0.758, P=0.941 and P=0.963, respectively. Multivariate Cox regression showed that donor age P=0.004 (HR: 1.016 and CI: 1.005-1.027), a recipient age P=0.023 (HR: 0.986 and CI: 0.974-0.998) and BMI P=0.001 (HR: 1.019 and CI: 1.010-1.028) were independent predictors of serum creatinine>100µmol/L at 1 year. The Pearson correlation coefficient r=0.154 (P=0.004) showed a significant correlation between BMI and serum creatinine. CONCLUSION: Our study showed that donor age, recipient age and BMI were independent predictors of renal function>100µmol/L at 1 year. Our results highlight the difficulty of the management of obesity in renal transplant patients. LEVEL OF EVIDENCE: 5.

RESUMEN

Hydrocele in adults is a collection of peritesticular fluid between the parietal and visceral layers of the tunica vaginalis testis. An endemic disease in Africa, its cause is either idiopathic or a reaction to filariasis. In the absence of treatment, its volume increases spontaneously. The onset of symptoms justifies treatment. In tropical zones, surgery is the most effective treatment. The technique must be simple to perform, require few resources, and limit the risks of complication. Three surgical techniques should be used. In resource-poor practice conditions, fenestration and, to a lesser extent, plication are the techniques most appropriate when the tunica vaginalis is essentially healthy. Only resection is possible when it is damaged.

RESUMEN

PURPOSE: Giant inguinoscrotal hernias represent a real public health problem in the Ivory Coast that can dramatically impair patients' quality of life. Limited resources require a simplified surgical strategy including, in our experience, not using a mesh and leaving the distal hernia sac. The aim of this study was to evaluate the benefits of this technique in terms of complications (seroma, haematoma, trophic troubles) and the ability to recover from surgery and return to work at 1 month postsurgery. METHODS: Between January and May 2012, all patients who presented with a giant primary inguinoscrotal hernia that was spontaneously reducible in the decubitus position and who did not have any trophic changes in the scrotal skin were prospectively studied. The surgical procedure was a herniorrhaphy as described by Bassini. All patients received follow-up examinations on postoperative days 5, 12 and 30. RESULTS: Twenty-five males with a median age of 42 years (range 18-60) underwent surgery. Three patients (12 %) presented with a superficial skin infection and four (16 %) with early scrotal swelling without seroma, spontaneously resolved by postoperative day 30. Three patients (12 %) presented with scrotal swelling and seroma; two required aspiration. No early recurrence was observed at the end of follow-up, and all patients were able to return to work. CONCLUSION: Leaving the distal hernial sac in the scrotum does not interfere with the type of hernia repair and can limit the occurrence of complications. This technique is reliable, reproducible and does not incur additional morbidity when used in selected patients.

RESUMEN

Giant inguinoscrotal hernias represent a real public health problem in Africa that can dramatically impair patients' quality of life. Limited resources require a simplified surgical strategy that can include herniorraphy followed by abandoning the distal hernia sac into the scrotum. The best eligibility criteria for such an approach are a primary giant inguinoscrotal hernia, spontaneously reducible in the decubitus position and without any scrotal cutaneous trophic disorders. This reproducible surgical treatment has to be efficient with rapid recover from surgery allowing return to work and social reintegration.

RESUMEN

Obstetrical vesicovaginal fistulas remain frequent in Africa. An isolated surgeon, making a short-term visit, must select cases with a good prognosis by thorough clinical examination. Surgery is the only treatment and is simple for these simple cases: debridement of both sides of the sclerotic fistula, making it possible to separate the vaginal and bladder walls and to suture each individually. This reproducible surgery must be effective to lead to the women's social reintegration. Accordingly, isolated surgeons must treat only simple cases.

RESUMEN

In contrast to endometritis, now diagnosed by cytological examination, the effect of endocervical inflammation on reproductive performance has been inadequately investigated. In this study, endocervical and endometrial cytological specimens were collected from 168 Holstein cows between 21 and 60 days in milk (DIM) to investigate the prevalence of endocervical inflammation and effect on days to conception. Statistical analyses were stratified based on DIM at examination (<35 vs. ≥35 DIM). Endocervical inflammation with ≥5% neutrophils before 35 DIM (disregarding the level of endometrial inflammation) was associated with decreased hazard of pregnancy within 300 DIM (adjusted hazard ratio, 0.4; 95% confidence interval: 0.3-0.8). A decrease in hazard of pregnancy was observed when >6% neutrophils were counted in endometrial smears (adjusted hazard ratio, 0.4; 95% confidence interval: 0.2-0.7). The study suggested an additive effect of combined endocervical and endometrial inflammation on the hazard of pregnancy within 300 DIM. Using the thresholds of 5% neutrophils for the cervix and 6% neutrophils for the uterus, 11% of the cows examined before 35 DIM presented cervicitis only, 13% were affected by endometritis only, and 32% suffered from both endometrial and endocervical inflammation. The presence (absence) of cervicitis was not indicative of the presence (absence) of endometritis. This study showed that in addition to uterine inflammation, endocervical inflammation in early lactation affects conception. Thus, the global evaluation of genital tract health may be more beneficial for reproductive performance than that of endometrial inflammation.

RESUMEN

The fungus Fusarium langsethiae, exclusively described in Europe at present, seems to have taken the place of other Fusarium species in barley fields over the last 5 years. It has proved to be a highly toxic type-A trichothecene producer (T-2 and HT-2 toxins). The aim of this work was to study the ecotoxinogenesis of this fungus the better to identify and manage the health risk it may pose during the beer manufacturing process. The influence of temperature and water activity on its growth rate and production of toxins are particularly assessed from a macroscopic point of view. Different cultures were grown on sterilized rehydrated barley with a water activity between 0.630 and 0.997 and a temperature ranging from 5 to 35 degrees C. Biomass specific to F. langsethiae and T-2 and HT-2 toxins were quantified by real-time polymerase chain reaction and liquid chromatography-mass spectrometry, respectively. It appears that the optimal temperature and water activity for F. langsethiae toxinogenesis are 28 degrees C and 0.997. This fungus was able to produce 2.22 g kg(-1) of these toxins in 16 days on barley in optimal production conditions. The malting process seems to be a critical step because, in its temperature range, specific production was six times higher than under optimal temperatures for fungus growth. In the short-term, this work will help redefine the process conditions for malting. In the medium-term, the results will contribute to the development of a molecular tool to diagnose the presence of this contaminant and the detection of the toxins in barley, from fields to the end product.

RESUMEN

An MEG experiment was carried out in order to compare the processing of lexical-tonal and intonational contrasts, based on the tonal dialect of Roermond (the Netherlands). A set of words with identical phoneme sequences but distinct pitch contours, which represented different lexical meanings or discourse meanings (statement vs. question), were presented to native speakers as well as to a control group of speakers of Standard Dutch, a non-tone language. The stimuli were arranged in a mismatch paradigm, under three experimental conditions: in the first condition (lexical), the pitch contour differences between standard and deviant stimuli reflected differences between lexical meanings; in the second condition (intonational), the stimuli differed in their discourse meaning; in the third condition (combined), they differed both in their lexical and discourse meaning. In all three conditions, native as well as non-native responses showed a clear MMNm (magnetic mismatch negativity) in a time window from 150 to 250 ms after the divergence point of standard and deviant pitch contours. In the lexical condition, a stronger response was found over the left temporal cortex of native as well as non-native speakers. In the intonational condition, the same activation pattern was observed in the control group, but not in the group of native speakers, who showed a right-hemisphere dominance instead. Finally, in the combined (lexical and intonational) condition, brain reactions appeared to represent the summation of the patterns found in the other two conditions. In sum, the lateralization of pitch processing is condition-dependent in the native group only, which suggests that language experience determines how processes should be distributed over both temporal cortices, according to the functions available in the grammar.

RESUMEN

Necrosis of the penis glans is commonly described after circumcision or strangulation. We report the case of a patient, opioid abuser, who presented an isolated glans necrosis after an injection of buprenorphin. The buprenorphin (Subutex) is a sublingual partial mu-opioid agonist used for the treatment of heroin dependance. Its intravenous or subcutaneous abuse is associated with local infection. The patient require a surgical intervention. After the failure of a mucosal graft, a soft skin graft was done.

RESUMEN

Arterio-ureteral fistula is a rare condition difficult to diagnose. The usual presentation associates acute paroxysmal hematuria with well-identified history and risk factors. We report the case of an 84-year-old man with a life-threatening complication of an ilio-ureteral fistula complicating an anastomotic iliac pseudoaneurysm after prothetic iliofemoral surgery, due to a fungic infection by Candida. After reporting the clinical case and the emergency surgical treatment, we present a review of the literature.

RESUMEN

Animal displacement plays a central role in many ecological questions. It can be interpreted as a combination of components that only depend on the animal (for example a random walk) and external influences given by the heterogeneity of the environment. Here we treat the case where animals switch between random walks in a homogeneous 2D environment and its 1D boundary, combined with a tendency for wall-following behaviour (thigmotactism) that is treated as a Markovian process. In the first part we use mesoscopic techniques to derive from these assumptions a set of partial differential equations (PDE) with specific boundary conditions and parameters that are directly given by the individual displacement parameters. All assumptions and approximations made during this derivation are rigorously validated for the case of exploratory behaviour of the ant Messor sanctus. These PDE predict that the stationary density ratio between the 2D (centre) and 1D (border) environment only depends on the thigmotactic component, not on the size of the centre or border areas. In the second part we test this prediction with the same exploratory behaviour of M. sanctus, in particular when many ants move around simultaneously and may interact directly or indirectly. The prediction holds when there is a low degree of heterogeneity (simple square arena with straight borders), the collective behaviour is "simply" the sum of the individual behaviours. But this prediction breaks down when heterogeneity increases (obstacles inside the arena) due to the emergence of pheromone trails. Our approach may be applied to study the effects of animal displacement in any environment where the animals are confronted with an alternation of 2D space and 1D borders as for example in fragmented landscapes.

RESUMEN

The human serine protease inhibitor (serpin) gene cluster at 14q32.1 comprises 11 serpin genes, many of which are expressed specifically in hepatic cells. Previous studies identified a locus control region (LCR) upstream of the human alpha1-antitrypsin (alpha1AT) gene that is required for gene activation, chromatin remodeling, and histone acetylation throughout the proximal serpin subcluster. Here we show that the LCR interacts with multiple liver-specific transcription factors, including hepatocyte nuclear factor 3beta (HNF-3beta), HNF-6alpha, CCAAT/enhancer binding protein alpha (C/EBPalpha), and C/EBPbeta. RNA polymerase II is also recruited to the locus through the LCR. Nongenic transcription at both the LCR and an upstream regulatory region was detected, but the deletion of the LCR abolished transcription at both sites. The deletion of HNF-3 and HNF-6 binding sites within the LCR reduced histone acetylation at both the LCR and the upstream regulatory region and decreased the transcription of the alpha1AT, corticosteroid binding globulin, and protein Z-dependent protease inhibitor genes. These results suggest that the LCR activates genes in the proximal serpin subcluster by recruiting liver-specific transcription factors and components of the general transcription machinery to regulatory regions upstream of the alpha1AT gene.
