Epidemiology of breast cancer in women based on diagnosis data from oncologists and senologists in Algeria.

BACKGROUND: Breast cancer (BC) is a major health issue threatening women's life. No reliable epidemiological data on BC diagnosed by oncologists/senologists are available in Algeria. METHODS: The BreCaReAl study, a non-interventional prospective cohort study, included adult women with confirmed BC in Algeria. Disease incidence, patients and disease characteristics, treatment patterns, and mortality rate were recorded up to 12 months of follow-up. RESULTS: Overall, 1,437 patients were analysed: median age was 48 [41;57] years and 337 (23.5%) women had a family history of BC. BC incidence was 22.3 (95% CI: 21.5; 23.2) cases per 100,000 inhabitants over 8 months. Delayed diagnosis was reported in 400 (29.2%) patients. First line of treatments were mainly chemotherapy and surgery. Twenty-eight serious adverse events were reported including 10 (37.0%) events which led to death. Mortality rate reached 3.2% at 12 months CONCLUSION: A delayed diagnosis highlights the importance of implementing more effective screening strategies.

BSGIE survey on COVID-19 and gastrointestinal endoscopy in Belgium : results and recommendations.

BACKGROUND AND AIMS: With the first wave of the COVID-19 pandemic declining, activities in the gastrointestinal clinic are being recommenced after a period of stringent measures. Since a second COVID-19 wave is not entirely ruled out health care professionals might remain faced with the need to perform endoscopic procedures in patients with a confirmed positive or unknown COVID-19 status. With this report we aim to provide a practical relevant overview of preparation and protective measures for gastroenterologists based on the currently available guidelines and our local experience and results of a national Belgian survey, to guarantee a fast recall of an adequate infection prevention if COVID-19 reoccurs. METHODS: From the 23rd of March 2020 and the 13th of May 2020 we performed a Pubmed, Embase and Medline search, resulting in 37 papers on COVID-19 and endoscopy. Additionally, we combined these data with data acquired from the national BSGIE survey amongst Belgian gastroenterologists. RESULTS: Based on 72 completed surveys in both university and non-university hospitals, the results show (1) a dramatic (<20%) or substantial (<50%) decrease of normal daily endoscopy in 74% and 22% of the units respectively, (2) a difference in screening and protective measures between university and non-university hospitals. These findings were subsequently compared with the current guidelines. CONCLUSION: Based on new data from the BSGIE survey and current guidelines we tried to realistically represent the current COVID-19 trends in protective measures, screening and indications for endoscopy and to provide a practical overview as preparation for a possible second wave.

Psoriasis and metabolic and cardiovascular comorbidities in children: A systematic review.

INTRODUCTION: Psoriasis is associated with a higher risk of cardiovascular and/or metabolic comorbidity in adults, but discordant data have been reported in children. OBJECTIVE: To evaluate the frequency of metabolic and cardiovascular comorbidity in children with psoriasis and to establish whether age at onset of psoriasis correlates with metabolic and cardiovascular comorbidity in adulthood. MATERIAL AND METHODS: We conducted a systematic review on MEDLINE, using PubMed and Ovid. The search was limited to children (<18 years). The following key words were used: "psoriasis" with "children or childhood or adolescent" and "obesity" or "hypertension" or "diabetes" or "dyslipidemia" or "cardiovascular risk factor" or "myocardial infarction" or "stroke" or "coronaropathy" or "comorbidity". The reference lists of the articles retrieved were checked for additional relevant studies. RESULTS: A total of 377 potential citations were analyzed. After removing duplicate articles and reviewing eligibility in titles and abstracts, 16 articles remained. The studies analyzed revealed significantly higher risk of overweight and obesity in children with psoriasis, despite the numerous definitions used. Four studies reported higher risk of abdominal obesity in children with psoriasis. Data on hypertension, diabetes, dyslipidemia, metabolic syndrome, and major cardiovascular events suggested there was no higher risk of these comorbidities in children with psoriasis. Two studies suggested that age at onset of psoriasis did not increase the frequency of comorbidity in adulthood. CONCLUSION: This systematic review suggests that psoriasis in children is not associated with metabolic and cardiovascular comorbidities, except overweight and obesity, for which higher prevalence is clearly demonstrated in the literature.

[Pemetrexed-induced eyelid edema]. / Œdème palpébral induit par le pemetrexed (Alminta®).

BACKGROUND: Drug-induced eyelid edemas are rare. Herein, we describe a patient who developed this type of edema under chemotherapy. PATIENTS AND METHODS: A 56-year-old male patient with a history of hypertension and adenocarcinoma of the lung with brain metastases consulted for incipient non-itchy eyelid edema with progressive worsening. The swelling occurred after 3 cycles of pemetrexed-carboplatin. There was no evidence of any other cause of edema. A diagnosis of pemetrexed-induced eyelid edema was made. Given the efficacy of this treatment and the patient's consent thereto, it was maintained. DISCUSSION: Palpebral edemas secondary to pemetrexed are very rare, with only 22 published cases in the literature. Other differential diagnoses must be ruled out before considering this etiology. The pathogenesis of eyelid edema remains unknown. One hypothesis is capillary protein leakage inducing swelling in soft tissue and non-malignant effusion, as has been suggested for docetaxel. Other agents such as tyrosine kinase inhibitors (imatinib and nilotinib) and mTOR inhibitors (sirolimus) may also cause eyelid edema. Treatment of eyelid edema is difficult and one case of surgical treatment has been published with good results and no recurrence after 6 months.

[Pitfalls for renogram interpretation in pediatric urology]. / Biais d'interprétation de la scintigraphie rénale chez l'enfant.

Renograms are currently used for functional assessment by pediatric urologists. The aim of the present work was to focus on the potential pitfalls concerning renography. Potential confounding factors are described in reference to concrete cases. The main types of pitfalls concern venous or urinary catheters and background area definition. Protocols and renogram interpretation are critiqued in a bibliographic review. We propose a technical update and original data on the potential pitfalls in renography interpretation. Multidisciplinary discussion between nuclear medicine, pediatrics and pediatric surgery departments is required before drawing conclusions.

Combined endoscopic ultrasonography and endobronchial ultrasound-fine-needle aspiration for evaluation of mediastinal lymph nodes.

OBJECTIVES: Endoscopic ultrasonography (EUS) and endobronchial ultrasound-fine-needle aspiration (EBUS-FNA), is an accurate technique for evaluation of mediastinal lymph nodes (MLN) and stadification of lung cancer. The aims of the study are to evaluate the feasibility and the efficacy of the combined technique compared with mediastinoscopy for the diagnosis of MLN. DESIGN AND METHODS: All patients with suspected malignant MLN and/or lung lesion identified by positron emission tomography-computed tomography underwent combined EUS-EBUS-FNA. The combined procedure was performed in outpatients under general anesthesia for EUS and sedation by intravenous midazolam for EBUS when performed separately, using linear-array echoendoscopes. The MLN were punctured during the EUS and EBUS-FNA procedures with a 22 gauge needle. RESULTS: Thirty-four patients underwent consecutively EUS and EBUS-FNA between September 2011 and November 2013 (8 women, 26 men, mean age of 65.9 year, range: 51-83). Combined EUS-EBUS-FNA was performed in a single time procedure in 26 patients (mean time 50 min) and in two different times in eight patients (mean delay 3 days). Twenty-five malignant and 9 inflammatory lesions were diagnosed. Mediastinoscopy was performed in nine patients and confirmed in eight patients the initial combined EUS-EBUS-FNA diagnosis. The diagnosis was obtained in 91.2% with EUS-FNA, 70.6% with EBUS-FNA and 97% when combined procedure was performed. The overall sensitivity, specificity, positive and negative predictive values of EUS-EBUS-FNA for diagnosing malignancy were 96.5%, 100%, 100% and 90% respectively. No complications related to the procedure were observed. CONCLUSION: Combined EUS-EBUS-FNA represents an accurate technique in the diagnosis of MLN, can be done in a single time procedure and has the advantage of being less invasive than mediastinoscopy.

Therapy response evaluation with FDG-PET/CT in small cell lung cancer: a prognostic and comparison study of the PERCIST and EORTC criteria.

INTRODUCTION: Small cell lung cancer (SCLC) is an aggressive form of lung cancer with poor prognosis. Adequate staging and therapeutic evaluation is necessary for therapy planning. Fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) has been shown to be useful for staging and therapy response evaluation. The European Organization for Research and Treatment of Cancer (EORTC) and Positron Emission Tomography Response Criteria In Solid Tumors (PERCIST) criteria were compared in the evaluation of response assessment and prognostic factors were defined in a cohort of SCLC patients. METHODS: Twenty-nine consecutive patients with SCLC were included in this study. Sixteen patients had extensive disease and 13 had limited disease. All patients had chemotherapy, 21 had thoracic radiotherapy. FDG-PET/CT scans were performed before and after therapy to evaluate treatment response. Metabolic responses were assessed using the EORTC criteria and PERCIST criteria. Univariate and multivariate analysis were performed using a Cox model to investigate the association between progression-free and overall survival time with a number of covariates. RESULTS: There was perfect concordance between the EORTC and PERCIST criteria. Eight patients had a complete metabolic response (CMR), 9 had a partial metabolic response (PMR), 5 had stable metabolic disease (SMD) and 7 had progressive metabolic disease (PMD). Overall survival time in patients with CMR was significantly longer compared with patients who did not have CMR. The initial or delayed CMR and post-therapeutic standardized uptake value corrected for lean body mass were significantly associated with overall survival. CONCLUSION: CMR on post-therapeutic FDG-PET/CT in patients with SCLC is an important prognostic factor and may help decision making for therapeutic management.

Chemotherapy response evaluation in metastatic colorectal cancer with FDG PET/CT and CT scans.

BACKGROUND: [18F]-fluorodeoxyglucose with positron-emission tomography (PET) and computed tomography (CT) scans were used to assess morphological and metabolic tumour response after chemotherapy in metastatic colorectal cancer. PATIENTS AND METHODS: Twenty-five patients were evaluated after 4 courses of chemotherapy (+/-target therapy), and among them 20 patients after 2 courses. Response Evaluation Criteria In Solid Tumors (RECIST) and European Organisazion for Research and Treatment of Cancer (EORTC) criteria were used to evaluate CT and PET respectively. RESULTS: Discrepancies between the two procedures were noted after 4 courses of chemotherapy in patient-based analysis. Two morphologically complete responses (CR) were correlated with metabolic response. Seven morphological partial responses (PR) were evaluated as 3 metabolic PR, 2 CR and 1 progressive disease (PD). Seventeen cases of morphologically stable disease (SD) were evaluated as 3 metabolic CR, 13 PR and 1 PD. These discrepancies were confirmed in lesion-based analysis. Perfect concordance was noted between metabolic responses obtained after 2 and 4 cycles. CONCLUSION: Morphological and metabolic imaging does not permit concordant therapeutic assessment in metastatic colorectal cancer.

Management of common bile duct stone late after laparoscopic Roux-en-Y gastric bypass for obesity.

Rapid weight loss following Roux-en-Y gastric bypass (RYGBP) for the treatment of obesity can increase the incidence of cholelithiasis formation. Nevertheless, routine simultaneous cholecystectomy at the time of bariatric surgery remains controversial. However, in case of delayed occurrence of common bile duct (CBD) stones, the difficulty to reach endoscopically the biliary tract after RYGBP should be kept in mind. We here report the case of a patient who presented with CBD stones seven years after gastric banding followed five years later by RYGBP without associated cholecystectomy. Our approach of transgastric laparoscopic assisted endoscopic retrograde cholangiopancreaticography followed by sphincterotomy and balloon stones extraction is illustrated.

Alcohol dependence is associated with reduced plasma and fundic ghrelin levels.

BACKGROUND: Conflicting data concerning the involvement of ghrelin in the pathophysiology of alcohol dependence have been reported. The aim of this study is to investigate how chronic alcohol ingestion influences plasma ghrelin levels and whether potential changes observed in plasma relate to modifications in ghrelin production in the stomach where this peptide is primarily synthesized. MATERIALS AND METHODS: Fifty-one consecutive alcoholics admitted for alcohol withdrawal were prospectively enrolled and compared to a control group of 32 healthy volunteers matched for age, sex, height and weight. All subjects underwent fasting plasma ghrelin determination. Twenty-seven randomly selected alcoholics and 17 controls underwent gastroscopy for fundic and duodenal biopsies. Tissues were fixed for histology or frozen in liquid nitrogen for ghrelin protein and mRNA determinations by a radioimmunoassay and quantitative polymerase chain reaction, respectively. Alcohol consumption was normalized to body weight (BW) or body mass index (BMI) given the influence of BW and volume distribution on alcohol levels. RESULTS: Plasma and fundic ghrelin protein levels were significantly decreased in alcoholics. Fundic but not plasma ghrelin protein levels inversely correlated with alcohol consumption normalized to BW or BMI. Ghrelin mRNA levels in fundic biopsies were similar in alcoholics and controls. No significant differences in duodenal ghrelin protein and mRNA levels were found between both groups. CONCLUSIONS: Alcoholism was associated with decreased plasma ghrelin levels partly due to reduced ghrelin production in the stomach. Alcohol affected ghrelin production on the post-transcriptional level in the fundus, whereas duodenal ghrelin secretion did not respond in a similar manner to alcohol intake.
