Systematic review of risk factors, prognosis, and management of colorectal signet-ring cell carcinoma. World J Gastrointest Oncol 2024; 16:2141-2158. [PMID: 38764832 PMCID: PMC11099453 DOI: 10.4251/wjgo.v16.i5.2141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Revised: 01/27/2024] [Accepted: 03/19/2024] [Indexed: 05/09/2024] Open
Abstract
BACKGROUND Colorectal signet-ring cell carcinoma (CSRCC) is a rare clinical entity which accounts for approximately 1% of all colorectal cancers. Although multiple studies concerning this specific topic have been published in the past decades, the pathogenesis, associated risk factors, and potential implications on treatment are still poorly understood. Besides the low incidence, historically confusing histological criteria have resulted in confusing data. Nevertheless, the rising incidence of CSRCC along with relatively young age at presentation and associated dismal prognosis, highlight the actual interest to synthesize the known literature regarding CSRCC. AIM To provide an updated overview of risk factors, prognosis, and management of CSRCC. METHODS A literature search in the MEDLINE/PubMed database was conducted with the following search terms used: 'Signet ring cell carcinoma' and 'colorectal'. Studies in English language, published after January 1980, were included. Studies included in the qualitative synthesis were evaluated for content concerning epidemiology, risk factors, and clinical, diagnostic, histological, and molecular features, as well as metastatic pattern and therapeutic management. If possible, presented data was extracted in order to present a more detailed overview of the literature. RESULTS In total, 67 articles were included for qualitative analysis, of which 54 were eligible for detailed data extraction. CSRCC has a reported incidence between 0.1%-2.4% and frequently presents with advanced disease stage at the time of diagnosis. CSRCC is associated with an impaired overall survival (5-year OS: 0%-46%) and a worse stage-corrected outcome compared to mucinous and not otherwise specified adenocarcinoma. The systematic use of exploratory laparoscopy to determine the presence of peritoneal metastases has been advised. Surgery is the mainstay of treatment, although the rates of curative resection in CSRCC (21%-82%) are lower compared to those in other histological types. In case of peritoneal metastasis, cytoreductive surgery with hyperthermic intraperitoneal chemotherapy should only be proposed in selected patients. CONCLUSION CSRCC is a rare clinical entity most often characterized by young age and advanced disease at presentation. As such, diagnostic modalities and therapeutic approach should be tailored accordingly.

A review on mechanistic insights into structure and function of dystrophin protein in pathophysiology and therapeutic targeting of Duchenne muscular dystrophy. Int J Biol Macromol 2024; 264:130544. [PMID: 38428778 DOI: 10.1016/j.ijbiomac.2024.130544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Revised: 02/09/2024] [Accepted: 02/28/2024] [Indexed: 03/03/2024]
Abstract
Duchenne Muscular Dystrophy (DMD) is an X-linked recessive genetic disorder characterized by progressive and severe muscle weakening and degeneration. Among the various forms of muscular dystrophy, it stands out as one of the most common and impactful, predominantly affecting boys. The condition arises due to mutations in the dystrophin gene, a key player in maintaining the structure and function of muscle fibers. The manuscript explores the structural features of dystrophin protein and their pivotal roles in DMD. We present an in-depth analysis of promising therapeutic approaches targeting dystrophin and their implications for the therapeutic management of DMD. Several therapies aiming to restore dystrophin protein or address secondary pathology have obtained regulatory approval, and many others are ongoing clinical development. Notably, recent advancements in genetic approaches have demonstrated the potential to restore partially functional dystrophin forms. The review also provides a comprehensive overview of the status of clinical trials for major therapeutic genetic approaches for DMD. In addition, we have summarized the ongoing therapeutic approaches and advanced mechanisms of action for dystrophin restoration and the challenges associated with DMD therapeutics.

Claudin-18.2 testing and its impact in the therapeutic management of patients with gastric and gastroesophageal adenocarcinomas: A literature review with expert opinion. Pathol Res Pract 2024; 254:155145. [PMID: 38277741 DOI: 10.1016/j.prp.2024.155145] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 01/10/2024] [Accepted: 01/16/2024] [Indexed: 01/28/2024]
Abstract
Claudin-18.2 (CLDN18.2) is a member of the tight junction protein family and is a highly selective biomarker with frequent abnormal expression during the occurrence and development of various primary malignant tumors, including gastric cancer (GC) and esophago-gastric junction adenocarcinomas (EGJA). For these reasons, CLDN18.2 has been investigated as a therapeutic target for GC/EGJA malignancies. Recently, zolbetuximab has been proposed as a new standard of care for patients with CLDN18.2-positive, HER2-negative, locally advanced and metastatic GC/EGJA. The use of CLDN18 IHC assays to select patients who might benefit from anti-CLDN18.2 therapy is currently entering clinical practice. In this setting, pathologists play a central role in therapeutic decision-making. Accurate biomarker assessment is essential to ensure the best therapeutic option for patients. In the present review, we provide a comprehensive overview of available evidence on CLDN18.2 testing and its impact on the therapeutic management of patients with GC/EGJA, as well as some practical suggestions for CLDN18.2 staining interpretation and potential pitfalls in the real-world setting.

Acute heart failure: mechanisms and pre-clinical models-a Scientific Statement of the ESC Working Group on Myocardial Function. Cardiovasc Res 2023; 119:2390-2404. [PMID: 37967390 DOI: 10.1093/cvr/cvad088] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 02/16/2023] [Accepted: 03/06/2023] [Indexed: 11/17/2023] Open
Abstract
While chronic heart failure (CHF) treatment has considerably improved patient prognosis and survival, the therapeutic management of acute heart failure (AHF) has remained virtually unchanged in the last decades. This is partly due to the scarcity of pre-clinical models for the pathophysiological assessment and, consequently, the limited knowledge of molecular mechanisms involved in the different AHF phenotypes. This scientific statement outlines the different trajectories from acute to CHF originating from the interaction between aetiology, genetic and environmental factors, and comorbidities. Furthermore, we discuss the potential molecular targets capable of unveiling new therapeutic perspectives to improve the outcome of the acute phase and counteracting the evolution towards CHF.

Abstract
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited arrhythmia syndrome characterized by bidirectional or polymorphic ventricular arrhythmia provoked by exercise or emotion. Most cases are caused by pathogenic variants in the gene encoding the cardiac ryanodine receptor (RYR2). The options for treating patients with CPVT have increased during the years, and evidence suggests that these have led to lower arrhythmic event rates. In addition, numerous potential new therapies are being investigated. In this review, we summarize the state of knowledge on both established and potential future treatment strategies for patients with CPVT and describe our approach to their management.

Abstract
Idiopathic pulmonary fibrosis (IPF) is a progressive devastating lung disease with substantial morbidity. It is associated with cough, dyspnea and impaired quality of life. If left untreated, IPF has a median survival of 3 years. IPF affects ∼3 million people worldwide, with increasing incidence in older patients. The current concept of pathogenesis is that pulmonary fibrosis results from repetitive injury to the lung epithelium, with fibroblast accumulation, myofibroblast activation, and deposition of matrix. These injuries, in combination with innate and adaptive immune responses, dysregulated wound repair and fibroblast dysfunction, lead to recurring tissue remodeling and self-perpetuating fibrosis as seen in IPF. The diagnostic approach includes the exclusion of other interstitial lung diseases or underlying conditions and depends on a multidisciplinary team-based discussion combining radiological and clinical features and well as in some cases histology. In the last decade, considerable progress has been made in the understanding of IPF clinical management, with the availability of two drugs, pirfenidone and nintedanib, that decrease pulmonary lung function decline. However, current IPF therapies only slow disease progression and prognosis remains poor. Fortunately, there are multiple clinical trials ongoing with potential new therapies targeting different disease pathways. This review provides an overview of IPF epidemiology, current insights in pathophysiology, diagnostic and therapeutic management approaches. Finally, a detailed description of current and evolving therapeutic approaches is also provided.

An international multicentre evaluation of treatment strategies for combined hepatocellular-cholangiocarcinoma ✰. JHEP Rep 2023; 5:100745. [PMID: 37234277 PMCID: PMC10206495 DOI: 10.1016/j.jhepr.2023.100745] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 02/14/2023] [Accepted: 03/15/2023] [Indexed: 05/27/2023] Open
Abstract
Background & Aims Management of combined hepatocellular-cholangiocarcinoma (cHCC-CCA) is not well-defined. Therefore, we evaluated the management of cHCC-CCA using an online hospital-wide multicentre survey sent to expert centres. Methods A survey was sent to members of the European Network for the Study of Cholangiocarcinoma (ENS-CCA) and the International Cholangiocarcinoma Research Network (ICRN), in July 2021. To capture the respondents' contemporary decision-making process, a hypothetical case study with different tumour size and number combinations was embedded. Results Of 155 surveys obtained, 87 (56%) were completed in full and included for analysis. Respondents represented Europe (68%), North America (20%), Asia (11%), and South America (1%) and included surgeons (46%), oncologists (29%), and hepatologists/gastroenterologists (25%). Two-thirds of the respondents included at least one new patient with cHCC-CCA per year. Liver resection was reported as the most likely treatment for a single cHCC-CCA lesion of 2.0-6.0 cm (range: 73-93%) and for two lesions, one up to 6 cm and a second well-defined lesion of 2.0 cm (range: 60-66%). Nonetheless, marked interdisciplinary differences were noted. Surgeons mainly adhered to resection if technically feasible, whereas up to half of the hepatologists/gastroenterologists and oncologists switched to alternative treatment options with increasing tumour burden. Fifty-one (59%) clinicians considered liver transplantation as an option for patients with cHCC-CCA, with the Milan criteria defining the upper limit of inclusion. Overall, well-defined cHCC-CCA treatment policies were lacking and management was most often dependent on local expertise. Conclusions Liver resection is considered the first-line treatment of cHCC-CCA, with many clinicians supporting liver transplantation within limits. Marked interdisciplinary differences were reported, depending on local expertise. These findings stress the need for a well-defined multicentre prospective trial comparing treatments, including liver transplantation, to optimise the therapeutic management of cHCC-CCA. Impact and implications Because the treatment of combined hepatocellular-cholangiocarcinoma (cHCC-CCA), a rare form of liver cancer, is currently not well-defined, we evaluated the contemporary treatment of this rare tumour type through an online survey sent to expert centres around the world. Based on the responses from 87 clinicians (46% surgeons, 29% oncologists, 25% hepatologists/gastroenterologists), representing four continents and 25 different countries, we found that liver resection is considered the first-line treatment of cHCC-CCA, with many clinicians supporting liver transplantation within limits. Nonetheless, marked differences in treatment decisions were reported among the different specialties (surgeon vs. oncologist vs. hepatologist/gastroenterologist), highlighting the urgent need for a standardisation of therapeutic strategies for patients with cHCC-CCA.

Abstract
INTRODUCTION AND OBJECTIVE Headache is a frequent reason for consultation between primary care physicians, emergency services physicians, and neurology specialists; however, it is not always well managed. The Andalusian Society of Neurology's Headache Study Group (SANCE) aimed to analyse headache management at different levels of care. MATERIAL AND METHODS We conducted a descriptive cross-sectional study with data gathered through a retrospective survey in July 2019. Participants completed a series of structured questionnaires on different social and work-related variables from 4 different groups of healthcare professionals (primary care [PC], emergency departments, neurology departments, headache units). RESULTS A total of 204 healthcare professionals completed the survey: 35 emergency department physicians, 113 PC physicians, 37 general neurologists, and 19 neurologists specialising in headache. Eighty-five percent of PC physicians reported prescribing preventive drugs, which were maintained for at least 6 months (59%), with flunarizine and amitriptyline being the most commonly used. Most patients attended at neurology consultations (65%) are referred by PC physicians, with changes in the headache pattern being the main reason for referral (74%). Healthcare professionals across all levels of care showed great interest in headache and in receiving training in headache management (97% of PC physicians, 100% of emergency services physicians, 100% of general neurologists). CONCLUSIONS Migraine sparks great interest among healthcare professionals from different levels of care. Our results also reveal a lack of resources for headache management, which is reflected in the long waiting times. Other means of bilateral communication between different levels of care should be explored (e.g., e-mail).

Abstract
While the incidence of gastric cancer (GC) in general has decreased worldwide in recent decades, the incidence of diffuse cancer historically comprising poorly cohesive cells-GC (PCC-GC) and including signet ring cell cancer is rising. Literature concerning PCC-GC is scarce and unclear, mostly due to a large variety of historically used definitions and classifications. Compared to other histological subtypes of GC, PCC-GC is nevertheless characterized by a distinct set of epidemiological, histological and clinical features which require a specific diagnostic and therapeutic approach. The aim of this review was to provide an update on the definition, classification and therapeutic strategies of PCC-GC. We focus on the updated histological definition of PCC-GC, along with its implications on future treatment strategies and study design. Also, specific considerations in the diagnostic management are discussed. Finally, the impact of some recent developments in the therapeutic management of GC in general such as the recently validated taxane-based regimens (5-Fluorouracil, leucovorin, oxaliplatin and docetaxel), the use of hyperthermic intraperitoneal chemotherapy as well as pressurized intraperitoneal aerosol chemotherapy and targeted therapy have been reviewed in depth for their relative importance for PCC-GC in particular.

Abstract
Background The efficacy of glucagon for adrenaline-resistant anaphylactic shock in patients taking β-blockers is controversial. However, understanding the efficacy of glucagon is important because adrenaline-resistant anaphylactic shock is fatal. We present a case of severe adrenaline-resistant anaphylactic shock in a patient taking a β-blocker, and glucagon was effective in improving hemodynamics. Case presentation An 88-year-old woman with severe aortic stenosis and taking a selective β-1 blocker underwent transcatheter aortic valve implantation under general anesthesia. Postoperatively, she received 100 mg sugammadex, but 2 min later developed severe hypotension and bronchospasm. Suspecting anaphylactic shock, we intervened by administering adrenaline, fluid loading, and an increased noradrenaline dose. Consequently, the bronchospasm improved, but her blood pressure only increased minimally. Therefore, we administered 1 mg glucagon intravenously, and the hypotension resolved immediately. Conclusions Glucagon may improve hemodynamics in adrenaline-resistant anaphylactic shock patients taking β-blockers; however, its efficacy must be further evaluated in more cases.

Abstract
Advanced heart failure, an end-stage disease characterized by high mortality and morbidity despite standard medical therapy, requires various therapeutic strategies like heart transplant and long-term mechanical circulatory support. Echocardiography is the main imaging technique to identify transitions to advanced stages of disease and guide risk stratification and therapeutic decision-making processes. Progressive development of advanced echocardiographic techniques allows more comprehensive assessment of the hemodynamic and structural profiles of patients with advanced heart failure, and its use in clinical practice continues to expand. This article provides an overview of basic and emerging echocardiographic tools to assess patients with advanced heart failure.

Abstract
Background The management of non-fermentative gram-negative bloodstream infection (NFGN-BSI) offers numerous challenges. In this study the aim is to analyse a large cohort of patients with NFGN-BSI recruited in the northern Italy to describe epidemiology, etiological and susceptibility pattern, therapeutic management and outcome. Methods Multicentre retrospective cohort study of patients hospitalised at three large teaching hospitals in northern Italy in a fourth year period. Results 355 BSI episodes were analyzed, due to P. aeruginosa (72.7%), A. baumannii (16.6%), and Stenotrophomonas maltophilia (10.7%). Overall, 21.4% of isolates were defined as DTR, highest rate among A. baumannii (64.4%). All-cause 30-day mortality rate was 17.5%. Rates of XDR or DTR A. baumannii isolation were significantly higher in non-surviving patients. Independent risk factors for 30-day mortality were: age (HR 1.03, 95%CI 1.00–1.04, p = 0.003), septic shock (HR 2.84, 95%CI 1.67–4.82, p < 0.001) and BSI due to Acinetobacter baumannii (HR 2.23, 95%CI 1.27–3.94, p = 0.005). Conclusion The overall prevalence of DTR was high in the NFGN BSI cohort analyzied, mainly among Acinetobacter baumannii episodes (64.4%). Acinetobacter baumannii is showed to be an independent predictor of mortality. These evidences marked the urgent need of new therapeutic options against this pathogen. Trial registration number: 79/2017/O/OssN. Approved: March14th, 2017. Supplementary Information The online version contains supplementary material available at 10.1186/s12879-021-06496-8.

Abstract
INTRODUCTION Delayed upper gastrointestinal (GI) bleeding is a rare complication of esophagectomy and can be difficult to manage. PRESENTATION A 76-year-old female represented 17 days post open esophagectomy with an unstable upper GI bleed. When control could not be achieved endoscopically, she was transferred to the Radiology Department where a triphasic CT angiogram confirmed active contrast extravasation into the gastric tube. She proceeded to the Interventional Radiology suite where a thoracic angiogram revealed an active arterial bleed from a branch of the thyrocervical trunk. The bleeding vessel was successfully embolised with coils and haemostasis was achieved. DISCUSSION Management options for upper GI bleeding post esophagectomy include medical, endoscopic and endovascular approaches. CONCLUSION Our case represents a rare example of delayed bleeding into a gastric conduit post open esophagectomy for a benign stricture. The case reinforces.

Abstract
OBJECTIVES The proper therapeutic management for acute type A aortic intramural hematoma (IMH) is still controversial. The purpose of this study was to compare the outcomes following emergency surgery or conservative treatment for patients with this disease. METHODS From January 2015 to December 2018, 124 consecutive patients were diagnosed with an acute type A aortic IMH and were included in this study. According to our surgical indications, they were divided into two groups: an operation group (OG) and a conservative treatment group (CG). RESULTS Of 124 patients, 83 (66.9%) patients accepted emergency surgery and 41 (33.1%) patients accepted strict conservative treatment. There were no differences between these two groups in early mortality and complications. However, the late mortality of patients in the CG was significantly higher than for patients in the OG. A maximum aortic diameter in the ascending aorta and aortic arch ≥ 45 mm and maximum thickness of IMH in the same section ≥ 8 mm were risk factors for IMH related death in patients undergoing conservative treatment. CONCLUSIONS The mortality associated with emergency surgery for patients with acute type A aortic IMH was satisfactory. In clinical centers with well-established surgical techniques and postoperative management, emergency surgical treatment may provide a better outcome than medical treatment for patients with acute type A aortic IMH.

Abstract
This is a case of voluntary ingestion of Nerium oleander leaves in an adolescent requiring the use of atropine and emergency chartering of antidigoxin antibodies (Digifab®) due to the difficulty of assessing oleandrin level and associated toxicity. Upon hospital admission, a digoxinemia was performed (0.44μg/mL) and the presence of oleandrine was detected. Oleandrin levels at toxic levels may be suspected by a measure of blood digoxin and explain the patient's clinical signs, which could adapt the therapeutic management.

Abstract
Neurodegeneration is a prevalent and one of the emerging reasons for morbidity, mortality, and cognitive impairment in aging. Dementia is one of such conditions of neurodegeneration, partially manageable, irreversible, and worsens over time. This review is focused on biological and psychosocial risk factors associated with Alzheimer's and Parkinson's diseases, highlighting the value of cognitive decline. We further emphasized on current therapeutic strategies from pharmacological and non-pharmacological perspectives focusing on their effects on cognitive impairment, protein aggregation, tau pathology, and improving the quality of life. Deeper mechanistic insights into the multifactorial neurodegeneration could offer the design and development of promising diagnostic and therapeutic strategies.

Abstract
Limited evidence exists regarding management of recurrent venous thromboembolism (VTE) that occurs during anticoagulant therapy. We aimed to describe patient characteristics, drug therapy management, and outcomes of patients with VTE recurrence during anticoagulant therapy. We identified 30 relevant episodes of VTE recurrence. Mean age was 48.9 (15.9) years, 56.7% were male, and 93.3% were White. Common VTE risk factors included cancer (46.6%), recent surgery (33.3%), and prolonged immobility (30.0%). At the time of recurrent VTE, 40.0% were receiving enoxaparin, 30.0% warfarin, and 23.3% direct oral anticoagulants. Potential causes for VTE recurrence included indwelling venous catheters (40.0%), cancer (33.3%), subtherapeutic anticoagulation (26.7%), and nonadherence (23.3%). Recurrent VTE management strategies included switching anticoagulants (26.7%), increasing anticoagulant dose (20.0%), temporarily adding enoxaparin or unfractionated heparin to oral anticoagulation therapy (13.3%), or no change in anticoagulation therapy (43.3%). Only four adverse 90-day outcomes occurred among 17 patients who received anticoagulant therapy changes in response to VTE recurrence, whereas eight adverse outcomes occurred in the 13 patients who received no change in anticoagulation therapy in response to a recurrent VTE episode (P value 0.04). Regardless of the potential etiology of recurrent VTE during anticoagulant therapy; switching anticoagulants, temporarily adding injectable anticoagulants, or increasing anticoagulant intensity appears preferable to continuing current anticoagulant therapy unchanged.

Abstract
Primary Gastrointestinal Angiosarcoma (PGAS) constitutes a rare malignant tumor arising from vascular or lymphatic endothelial cells. The aim of this study was to review the available literature on PGAS and to elucidate its biological behavior and optimal therapeutic approach. PubMed and Embase bibliographical databases were systematically searched (last search April 8th, 2020) for studies concerning PGAS. Ninety-eight studies met our inclusion criteria, involving 110 patients (male/female = 1.5) with an age of 62.40 ± 17.84 (mean, SD) years. They were most frequently located at small (44.5%) and large intestine (35.5%), while 12.7% were multifocal. Surgical resection of the tumor was conducted at 84.0% of the cases combined with adjuvant therapy at 12.3%. One-year cumulative survival was 55.18% (95% CI: 34.33%-71.84%) for large intestine, 30.2% (95% CI: 17.1%-44.5%) for small intestine, whereas multifocal PGAS had a 6-months cumulative survival of 23.08% (95% CI: 5.58%-47.46%). Therefore, PGAS is an extremely rare entity with atypical clinical presentation, challenging diagnosis and aggressive behavior. High clinical suspicion is crucial for its prompt management. Further studies and the development of novel therapeutic agents are required in order to improve survival.

Combined hepatocellular-cholangiocarcinoma: An update on epidemiology, classification, diagnosis and management. Hepatobiliary Pancreat Dis Int 2020; 19:515-523. [PMID: 32753331 DOI: 10.1016/j.hbpd.2020.07.004] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Accepted: 07/17/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND Combined hepatocellular-cholangiocarcinoma (CHC) is a rare subtype of primary hepatic malignancies, with variably reported incidence between 0.4%-14.2% of primary liver cancer cases. This study aimed to systematically review the epidemiological, clinicopathological, diagnostic and therapeutic data for this rare entity. DATA SOURCES We reviewed the literature of diagnostic approach of CHC with special reference to its clinical, molecular and histopathological characteristics. Additional analysis of the recent literature in order to evaluate the results of surgical and systemic treatment of this entity has been accomplished. RESULTS The median age at CHC's diagnosis appears to be between 50 and 75 years. Evaluation of tumor markers [alpha fetoprotein (AFP), carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA)] along with imaging patterns provides better opportunities for CHC's preoperative diagnosis. Reported clinicopathologic prognostic parameters possibly correlated with increased tumor recurrence and grimmer survival odds include advanced age, tumor size, nodal and distal metastases, vascular and regional organ invasion, multifocality, decreased capsule formation, stem-cell features verification and increased GGT as well as CA19-9 and CEA levels. In case of inoperable or recurrent disease, combinations of cholangiocarcinoma-directed systemic agents display superior results over sorafenib. Liver-directed methods, such as transarterial chemoembolization (TACE), percutaneous ethanol injection (PEI), hepatic arterial infusion chemotherapy (HAIC), radioembolization and ablative therapies, demonstrate inferior efficacy than in cases of hepatocellular carcinoma (HCC) due to CHC's common hypovascularity. CONCLUSIONS CHC demonstrates an overlapping clinical and biological pattern between its malignant ingredients. Natural history of the disease seems to be determined by the predominant tumor element. Gold standard for diagnosis is histology of surgical specimens. Regarding therapeutic interventions, major hepatectomy is acknowledged as the cornerstone of treatment whereas minor hepatectomy and liver transplantation may be applied in patients with advanced cirrhosis. Despite all therapeutic attempts, prognosis of CHC remains dismal.

Abstract
The present investigation was carried out to study the epidemiology, clinical signs, bleeding profile, kidney function, and pathology and to evaluate the therapeutic protocol for viperine snake envenomation in zebu cattle over a period of 14 years. A total of 98 cases of viperine bite were reported with the highest incidence during monsoon months in grazing male zebu cattle. Ascending swelling over the affected limb with lameness or asymmetrical swelling over the face with dyspnea was a consistent clinical finding. Increased bleeding tendency was invariably observed in ailing cattle with major bleeding from the site of the bite. Hematobiochemistry showed neutrophilic leukocytosis, thrombocytopenia, prolonged capillary blood clotting time, and elevation of BUN and creatinine. The characteristic gross pathological lesions observed were widespread petechial to ecchymotic hemorrhages in the lungs, liver, heart, spleen, abomasal mucosa, and intramuscular or subcutaneously at the site of bite. Histopathological examination revealed presence of necrohemorrhagic changes within the liver, heart, kidneys, skeletal muscles, and subcutaneously or intradermally at the site of bite. Diagnosis of viperine snakebite was made based on circumstantial evidence of bite, progressive swelling, and bleeding at the site of bite. The severity was assessed based on prolongation of capillary blood clotting time, thrombocytopenia, and kidney dysfunction. Therapeutic protocol comprising polyvalent anti-snake venom along with supportive therapy for 5-9 days showed encouraging results with 88.30% survival rate. In conclusion, the precise diagnosis of viperine snake envenomation in cattle can be made from history and typical clinical signs while severity and treatment can be monitored based on bleeding profile.

Abstract
There is no consensus on the treatment for solitary rectal ulcer syndrome (SRUS). This study aimed to obtain information from physicians treating patients with SRUS in a French medical surgical society to facilitate management plans and to develop a support algorithm. Members of the French National Society of Coloproctology (SNFCP) were invited to complete a survey that included twenty items about therapeutic management and healing criteria. Overall, 91 practitioners (median age: 52 [42-59] years) responded to the questionnaire; 64/91 (70.3%) were proctologists, and 27/91 (29.7%) were colorectal surgeons. Only 15 members (16.5%) followed more than 5 patients with SRUS per year. The therapeutic objectives were to improve both patient symptoms (100%) and quality of life (98.9%). Laxative treatment and first-line rehabilitation were agreed upon by 83.5% and 73% of the respondents, respectively. Surgery, mainly rectopexy, was offered after failed medical treatment by 81.1% of the practitioners (79.1%). The first-line strategy preferred by the professionals included laxatives and biofeedback rehabilitation. Surgical treatment, preferably rectopexy, was proposed as a second intervention. No consensus was reached regarding other therapeutic alternatives, and additional studies are required to clarify their indications.

A retrospective study on the predictive implications of clinical characteristics and therapeutic management in patients with rheumatoid arthritis-associated interstitial lung disease. Clin Rheumatol 2019; 39:1457-1470. [PMID: 31858341 DOI: 10.1007/s10067-019-04846-1] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2019] [Revised: 10/08/2019] [Accepted: 11/04/2019] [Indexed: 12/16/2022]
Abstract
BACKGROUND Rheumatoid arthritis (RA)-associated interstitial lung disease (ILD) is associated with significant morbidity and is a critical cause of mortality in patients with RA. OBJECTIVE Our aim was to evaluate predictive and prognostic factors for RA-ILD and to describe the therapeutic management of the condition from a large China cohort. METHODS This was a retrospective cohort study. We collected data of 1121 RA patients who underwent chest HRCT from 2008 to 2017. Patients without ILD at RA diagnosis were included in the analysis. The development and evolution of ILD in RA patients were followed up. Determinants of ILD development and progression were identified through multivariable logistic analysis. Cox hazards analysis was used to determine significant variables associated with survival. RESULTS A total of 923 patients without ILD at RA diagnosis were identified and enrolled. Among them, 278 cases (30.12%) were diagnosed as ILD during follow-up. Logistic regression analysis showed that advanced age (> 60 years old) at RA onset (OR: 1.485), male (OR: 1.882), short duration of RA (0~5 years) (OR: 2.099), RF positive (OR: 1.728), elevated lactate dehydrogenase (LDH) (OR: 3.032), and no medication (OR: 1.833) were closely correlated to the development of RA-ILD. No correlation was found between ILD development and traditional DMARDs such as methotrexate and leflunomide. According to the follow-up data, 83 RA-ILD patients were identified as interstitial lung disease (ILD) progression, and 102 participants were stable. Logistic regression modeling demonstrated that DLCO% < 45% (OR: 3.025) and UIP possible pattern on HRCT (OR: 3.476) were independent risk factors for the ILD progression. No correlation was found between ILD progression and traditional DMARDs such as methotrexate and leflunomide. A total of 53 RA-ILD deaths occurred during follow-up. Cox hazards analysis revealed that advanced age (> 60 years old) at RA-ILD diagnosis (HR: 3.181) and extensive lung involvement on HRCT (HR: 2.401) were associated with worse survival. Treatment with cyclophosphamide (HR: 0.210) was associated with better survival. CONCLUSIONS Advanced age, male, short duration of RA, RF positive, elevated LDH, and no medication are closely correlated with RA-ILD. No correlation was found between traditional DMARDs and ILD development. DLCO% < 45% and UIP possible pattern are predictive factors for ILD progression. No correlation was found between traditional DMARDs and ILD progression. Advanced age and extensive lung involvement on HRCT independently predict mortality; cyclophosphamide treatment helps to improve the prognosis of RA-ILD.Key Points• We designed this study to investigate the predictive and prognostic factors for RA-ILD and to explore the potential role of DMARDs in the evolution of RA-ILD from the development to progression and death.• Patients without ILD at RA diagnosis were enrolled and followed up retrospectively.• Our results showed that no correlation was found between traditional DMARDs and the development and progression of ILD, and regular treatment may improve the development of RA-ILD.• Our results revealed that clinical variables appeared predictive implications for the diagnosis of ILD and physiological and radiological variables appeared predictive implications for the prognosis of ILD, which can provide reference to rheumatologists and help to improve poor prognosis of RA-ILD.

Abstract
BACKGROUND Synovial sarcoma (SS) is a rare type of soft tissue sarcoma that is usually developed from areas where synovial tissue exists, especially at the extremities. Nevertheless, several cases of retroperitoneal SS (RSS) have been described. We herein report a case of RSS presented in our institution.
CASE SUMMARY A 69-year-old female patient was admitted with a large, palpable, firm mass in the right abdominal space SS. Computerized tomography scan depicted a concentric, sharply marinated retro-peritoneal lesion which was displacing the right kidney and the lower edge of the liver. Subsequently, the patient underwent surgical excision of the mass with additional right nephrectomy and resection of the right adrenal gland and a part of the diaphragm. The final histological diagnosis of the tumour was grade II monophasic RSS.
CONCLUSION RSS is encountered in the biphasic type, the monophasic fibrous, and the monophasic epithelial category as well. Relevant clinical manifestations are not always documented at early stages. Therefore, the final diagnosis is posed after complete histological examination taking into consideration the results of immunochemistry and genetic analysis. Therapeutic approach happens often late when metastases at the lungs and the liver are apparent. Thus, 5-year survival rates remain low.

Abstract
BACKROUND The radiosurgical management of high flow arteriovenous malformations (HFAVM) in the "destructive" stage requires a precise hemodynamic and anatomical assessment. PATIENT AND METHODS/CASE REPORT We report the case of a 32 years-old patient with a large ulcerated face HFAVM, on which Doppler ultrasound was impossible to perform. We show that, by combining 3D PCA and 2D CINE PC-MRI sequences, magnetic resonance imaging is capable to provide a complete morphometric and velocimetric mapping of the nidus and feeding arteries of the HFAVM. CONCLUSION Although Doppler ultrasound is the reference examination in the HFAVM, Flow MRI without contrast agent provides an advantageous alternative to assess vascular pathologies and choose the therapeutic strategy.

Abstract
Abdominal aortic aneurysm (AAA) is a vascular pathology with a high rate of morbidity and mortality and a prevalence that, in men over 65 years, can reach around 8%. In this disease, usually asymptomatic, there is a progressive dilatation of the vascular wall that can lead to its rupture, a fatal phenomenon in more than 80% of cases. The treatment of patients with asymptomatic aneurysms is limited to periodic monitoring with imaging tests, control of cardiovascular risk factors and treatment with statins and antiplatelet therapy. There is no effective pharmacological treatment capable of limiting AAA progression or avoiding their rupture. At present, the aortic diameter is the only marker of risk of rupture and determines the need for surgical repair when it reaches values greater than 5.5cm. This review addresses the main aspects related to epidemiology, risk factors, diagnosis and clinical management of AAA, exposes the difficulties to have good biomarkers of this pathology and describes the strategies for the identification of new therapeutic targets and biomarkers in AAA.

Abstract
We present a case of adrenal CD in a 26-year-old female. The patient was referred to our hospital because of left flank pain for 1 wk. A computed tomography scan revealed a 4 cm × 3 cm well-defined mass, considered as a paraganglioma. A preoperative diagnosis of left adrenal neoplasm and urinary tract infection was made. The patient underwent anti-inflammatory therapy followed by an open operation to remove the mass in the left adrenal. Through analysis of the morphological pattern and immunohistochemical markers, a diagnosis of CD was made. During the 12-mo follow-up, there was no evidence of metastasis or recurrence. This case reminds clinicians that CD should be considered in the evaluation of an adrenal mass. Surgery is suggested for its therapeutic management.

Abstract
INTRODUCTION Neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms composed of cells containing dense-core neuroendocrine secretory granules in their cytoplasm. NETs of the esophagus are exceedingly uncommon, with a parallel absence of data published on clinical features, prognosis, and proposed treatment strategies. METHODS As relevant classification is not well-established, knowledge acquired in NETs of lung and gastrointestinal sites usually guides esophageal NET management. Associated subtypes are divided based upon shared neuroendocrine features into small and large cell NET, typical and atypical carcinoid. RESULTS Common presenting symptoms include dysphagia, abdominal discomfort, weight loss, melena, and on occasion, signs of carcinoid syndrome. Endoscopic findings describe a polypoid, nodular elevated lesion with an overlying surface depicted as mostly smooth and glistening. Disease metastasis is assessed using anatomical imaging, including computed tomography (CT), endoscopic ultrasonography (EUS), and positron emission tomography (PET)-CT. Prognosis is influenced by the extent of lymph node metastasis and potential lymphovascular invasion. Furthermore, proliferative activity, estimated using mitotic count or Ki-67 immunostaining, has been suggested as a significant prognostic parameter. CONCLUSION Therapeutic approach depends on clinical staging. Nevertheless, currently, a specific treatment algorithm for esophageal NETs has not been elucidated. Endoscopic resection has been proposed in NETs less than 1 cm in size with absence of regional lymph node metastasis, while surgical excision combined with adjuvant chemotherapy remains the treatment of choice.

Abstract
OBJECTIVES To analyze the impact of tumor p16 status and other clinical factors on the therapeutic decision-making process in patients with oropharyngeal squamous cell carcinoma (OPSCC). METHODS We conducted a multicenter retrospective study (GETTEC collaborative study group) enrolling all OPSCC patients with a determined p16-status considered eligible for surgery between 2009 and 2014. The impact of p16-status and other clinical factors on the therapeutic decision was evaluated in multivariate analysis. RESULTS A total of 476 patients were enrolled in the study, including 244 cases (51%) of p16-positive OPSCC. Overall, 223 (47%) patients underwent primary surgery, and 184 (83%) of them received postoperative radiotherapy ± chemotherapy. More patients with p16-positive OPSCC tended to undergo non-surgical treatment than did patients with p16-negative OPSCC (p = 0.10). Multivariate analysis showed that 5 factors significantly influenced therapeutic management of the patients: T-stage ≥ 3 (towards a non-surgical strategy; p < 0.001), N-stage ≥ 2a (non-surgical strategy; p = 0.02), tumor involvement of the glosso-tonsillar sulcus (surgical strategy; p = 0.002), tumor extension to the oral cavity (surgical strategy; p < 0.009) and the center of care (p < 0.001). The rate of patients directed towards a surgical strategy varied between 9% and 74% depending on the center. CONCLUSION There was a non-significant trend to recommend patients with p16-positive OPSCC for non-surgical treatment. Center of care, tumor stage and tumor anatomical subsite and extensions were the main determinants of the treatment choice.

Abstract
Background Neoadjuvant chemoradiotherapy (CRT) is considered the standard approach before any surgical intervention for locally advanced rectal tumors and has been proven to significantly improve the local recurrence rates of rectal cancer. However, the optimal timing of surgical resection after neoadjuvant CRT remains debatable. Objective and Methods We conducted a retrospective review of 65 consecutive patients with locally advanced rectal cancer who underwent preoperative CRT followed by surgical resection in order to evaluate the optimal time for surgical treatment. We used two alternative groups for analysis: patients who underwent surgery up to 6 weeks after CRT (n = 28) and those who underwent surgery 6 weeks or more after CRT (n = 27). Also, we compared patients who were operated on within 3 months (n = 39) with those who underwent surgical resection after more than 3 months (n = 16). Nonresponders to CRT were excluded from the analysis. Results There was no statistically significant association between waiting period post CRT and radiological downstaging for any group (p > 0.05 for any association). Also, there was no association between recurrence of disease, cancer-related deaths, perineural invasion, or positive lymph node ratio and any waiting period up to 3 months (p > 0.05 for all associations). Conclusion In this small exploratory study there was no evident difference in outcome according to timing of surgery, which suggests that further research in larger cohorts is warranted.

Abstract
BACKGROUND/AIMS Our physicians work to expand the possibilities to treat female patients with inflammatory bowel disease (IBD) who wish to become pregnant. Although many drugs, including 5-aminosalicylate (5-ASA), corticosteroids, immunomodulators, and biologics, are used safely during pregnancy, few reports have described the therapeutic regimen throughout pregnancy and the management of patients who relapse during pregnancy precisely. The aim of this study was to assess the management of patients with IBD during pregnancy. METHODS We identified 19 patients (five with Crohn's disease and 14 with ulcerative colitis [UC]) who became pregnant with a total of 23 pregnancies between May 2005 and May 2015 by reviewing the medical records of Kyoto University Hospital. The following data were collected: the maternal variables, the IBD treatment type, the disease activity, the pregnancy outcome, and the mode of delivery. RESULTS Among the 19 patients, 18 had become pregnant after being diagnosed with IBD, while one had developed UC newly after pregnancy. Throughout the gestation, all patients were treated with probiotics, 5-ASA, prednisolone, cytapheresis, or infliximab. The relapse rate during pregnancy was 21.7% (5/23 cases). The five patients who experienced a relapse were able to pursue their pregnancy after intensification of their treatments. There were no adverse fetal or neonatal problems, except in one case that required an emergency Caesarean section because of placental dysfunction and in which a very low-birth-weight infant was born preterm. CONCLUSIONS Our present data confirmed that even if the disease flares up during pregnancy, good pregnancy outcomes can be achieved with an optimal intensification of the patient's treatment.

Abstract
BACKGROUND The Rutgeerts score with 5 grades of severity (i0-i4) is a suitable endoscopic model to predict clinical recurrence following ileocolonic resection in Crohn's disease (CD). Definition of grade i2 includes lesions confined to the ileocolonic anastomosis (i2a) or moderate lesions on the neo-terminal ileum (i2b). The aim of the present study was to evaluate the probability of clinical recurrence in i2a and i2b patients. METHODS This multicenter retrospective study included all CD patients classified i2 at the first postoperative ileocolonoscopy. The primary outcome was to evaluate the probability of clinical recurrence in patients classified i2a and i2b. The secondary outcome was to compare the rate of global recurrence of CD. RESULTS Fifty patients were included: 23 were classified i2a and 27 were classified i2b. The median duration of follow-up was 40 (18.0-80.4) months in the i2a group and 53.5 (25.0-69.0) months in the i2b group (p = 0.9). The probability of clinical recurrence was not significantly different between patients classified i2a and i2b (p = 0.64). Median time to clinical recurrence after the first ileocolonoscopy and probability of global CD recurrence were not different between the two groups (p ≥ 0.19). CONCLUSIONS The rate of clinical postoperative recurrence is not different in i2a and i2b patients. These results suggest that the same therapeutic strategy should be used in all patients classified i2 on the Rutgeerts score whatever the location of postoperative CD recurrence.

Abstract
This study is based on naturally intoxicated Doberman pinscher pups. Six Doberman pinscher pups were overdosed 50 times of recommended ivermectin dose by the pet owner and presented to Referral Veterinary Polyclinic section of this institute in a state of coma. The pups were unable to hold their head up and had no pupillary reflex. The pups were examined clinically and samples of blood were taken for haemato-biochemical studies, before and after treatment. During intoxication there was marked haemoconcentration, increase in values of serum creatinine phosphokinase, gamma glutamyl transpeptidase but decrease in serum glucose levels. These pups were treated with isotonic dextrose normal saline, 1.0 mg/kg physostigmine and 3 mg/kg dexamethasone. Clinical improvement occurred in remaining 2 pups after 12 h of treatment. These pups were able to take a liquid diet after 3 day and became clinically normal after 2 week. The serum biochemical values gradually reached to normal in recovered pups after 2 weeks of treatment. It took a month for complete recovery from depression and blindness.

Abstract
Little is known about the role in ongoing risk stratification of fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) performed early after radioactive iodine (RAI) ablation in differentiated thyroid carcinoma (DTC). The aim of the study is to investigate whether 18F-FDG PET/CT performed early after RAI ablation is useful to detect disease and to influence therapy and ongoing risk stratification. Patients with high/intermediate risk of recurrent DTC were included. 18F-FDG PET/CT scan was performed within 6 months after RAI ablation. We confirmed results with other imaging techniques, pathology reports, or follow-up. We classified the patient response as excellent, acceptable, or incomplete. Modified Hicks criteria were used to evaluate clinical impact. We included 81 patients with high/intermediate risk of recurrent DTC. Forty-one (50.6%) had positive uptake in 18F-FDG PET/CT, with negative (131)I whole-body scan ((131)I WBS). Sensitivity, specificity, and diagnostic accuracy of 18F-FDG PET/CT were 92.5, 90.2, and 91.4%, respectively. 18F-FDG PET/CT results had an impact on therapy in 38.3% of patients. One year after initial therapy, 45.7% showed excellent response, 8.6% acceptable response, and 45.7% incomplete response. A statistically significant relationship was found between negative 18F-FDG PET/CT and excellent response (80 vs. 12.2%, p < 0.001; OR 52.8). 18F-FDG PET/CT scan performed early in surveillance of patients with high/intermediate-risk thyroid carcinoma provides important additional information not available with conventional follow-up methods and had a high impact on therapy. A negative 18F-FDG PET/CT predicts an excellent response to therapy in the new ongoing risk stratification.

Abstract
Mesenteric ischemia (MI) is an uncommon medical condition with high mortality rates. ΜΙ includes inadequate blood supply, inflammatory injury and eventually necrosis of the bowel wall. The disease can be divided into acute and chronic MI (CMI), with the first being subdivided into four categories. Therefore, acute MI (AMI) can occur as a result of arterial embolism, arterial thrombosis, mesenteric venous thrombosis and non-occlusive causes. Bowel damage is in proportion to the mesenteric blood flow decrease and may vary from minimum lesions, due to reversible ischemia, to transmural injury, with subsequent necrosis and perforation. CMI is associated to diffuse atherosclerotic disease in more than 95% of cases, with all major mesenteric arteries presenting stenosis or occlusion. Because of a lack of specific signs or due to its sometime quiet presentation, this condition is frequently diagnosed only at an advanced stage. Computed tomography (CT) imaging and CT angiography contribute to differential diagnosis and management of AMI. Angiography is also the criterion standard for CMI, with mesenteric duplex ultrasonography and magnetic resonance angiography also being of great importance. Therapeutic approach of MI includes both medical and surgical treatment. Surgical procedures include restoration of the blood flow with arteriotomy, endarterectomy or anterograde bypass, while resection of necrotic bowel is always implemented. The aim of this review was to evaluate the results of surgical treatment for MI and to present the recent literature in order to provide an update on the current concepts of surgical management of the disease. Mesh words selected include MI, diagnostic approach and therapeutic management.

Abstract
Chronic kidney disease and high blood pressure are two common diseases that mutually maintain during their evolution. In the advanced stages of chronic kidney disease, most pat ients are hypertensive and show signs of vascular disease (coronary artery disease, cerebrovascular or peripheral). Almost one third of the patients with advanced chronic kidney disease exhibit resistant hypertension that requires complex therapeutic management. In chronic kidney disease, antihypertensive treatment is conditioned by comorbidities, but also by proteinuria, which is an independent cardiovascular risk factor in addition to the rate of glomerular filtration rate. The treatment of high blood pressure is a cornerstone of the management of the chronic kidney disease. It limits the risk of cardiovascular events (eg. myocardial infarction, stroke), but also slows the progression of chronic kidney disease. Various recommendations have been recently published on the subject in order to offer assistance to the therapeutic management of hypertension in the patient suffering from chronic kidney disease. The purpose of this article is to highlight these main key elements.

Abstract
The study of specific differences between women and men is arousing huge interests in various fields of medicine, including dermatology. The available data on gender medicine applied to common skin diseases are unfortunately still scanty. Psoriasis is a chronic immune-mediated skin disease which affects 1%-3% of most populations worldwide and can involve also the joints and entheses. The pathogenesis of the disease is very complex, resulting from the interaction between genetic predisposition and several environmental triggers. The pathogenic role of sex hormones has also been hypothesized. The analysis of gender-specific differences in psoriasis seems to suggest some interesting findings, such as an earlier age of disease onset in females, a higher probability of severe disease in men, or different tendencies in care utilization, adherence to treatment, development of psychological distress, and coping strategies. Moreover, sex-related differences have been recently described in some epidemiological and clinical features among patients with psoriatic arthritis. The objective of this article is to review briefly the available evidence regarding gender differences in various aspects of psoriasis, such as epidemiology, genetics, risk factors, associated conditions, quality of life, clinical and therapeutic aspects.

Abstract
Acute gastrointestinal bleeding (GIB) can lead to significant morbidity and mortality without appropriate treatment. There are numerous causes of acute GIB including but not limited to infection, vascular anomalies, inflammatory diseases, trauma, and malignancy. The diagnostic and therapeutic approach of GIB depends on its location, severity, and etiology. The role of interventional radiology becomes vital in patients whose GIB remains resistant to medical and endoscopic treatment. Radiology offers diagnostic imaging studies and endovascular therapeutic interventions that can be performed promptly and effectively with successful outcomes. Computed tomography angiography and nuclear scintigraphy can localize the source of bleeding and provide essential information for the interventional radiologist to guide therapeutic management with endovascular angiography and transcatheter embolization. This review article provides insight into the essential role of Interventional Radiology in the management of acute GIB.

Abstract
OBJECTIVE To describe the clinical impact of PET/CT in the management of patients with vulvar cancer. MATERIAL AND METHODS Retrospective analysis of 13 PET/CT studies with (18)F-FDG (6 staging and 7 suspected recurrence) corresponding to 10 patients diagnosed with vulvar cancer by biopsy, with a mean age of 64.5 years. The preoperative PET/CT study was analyzed qualitatively according to the lesion region. Surgical excision was carried out, covering all the suspected areas according to the PET/CT study. This was compared with the histopathologic analysis. RESULTS Abnormal vulvar PET/CT uptake was found in 9 out of the 13 studies and invasion of adjacent structures in 5 of them (urethra, perineal, vagina). The inguinal-femoral lymph nodes were considered as affected in 3 studies and one pelvic lymph node was also affected. Four of the studies had extralymphatic involvement: 3 in lung and 1 in ischiorectal fossa. The PET/CT showed a 100% sensitivity for the detection of the vulvar lesion in squamous cell carcinomas and 60% in non-squamous cell ones. There was a false positive result for local invasion due to urine contamination. One of the studies with lung metastases was related to a synchronous breast tumor. All the pathological lymph node levels detected in the PET/CT study were confirmed in the histopathology study. No new lesions were identified by surgery. PET/CT changed the therapeutic management in 8/13 studies (61.5%). CONCLUSIONS PET/CT is postulated as a useful imaging test for the management of vulvar cancer, mainly in the identification of nodal metastases. It may affect both surgical planning and clinical management. Larger series are needed to confirm our findings.

Abstract
The occurrence of Eimeria leukarti infection in equine is being sporadically documented despite its cosmopolitan prevalence. A Marwari mare, aged 3 years and 6 months and owned by a socio-economically weaker class of labourer of royal families, was suffering from non specific enteric disorders. Detailed systemic clinical examination of mare confirmed subclinical enteric infection with E. leukarti and piroplasms of Babesia (Theileria) equi in the circulating erythrocytes. She was therapeutically managed with synchronous administration of specific and supportive therapy with success. Non specific clinical manifestations of the disease in equines, its debatable pathogenic significance, predisposing immunosuppressive impact of concurrent B. (T.) equi in circulating erythrocytes and probable reasons for under reporting of the disease in equines, etc. have been discussed.

Abstract
The most common causes of steatohepatitis are alcohol intake and metabolic disorders. Several methods based on biochemical determinations (carbohydrate deficient transferrin) and questionnaires (AUDIT, CAGE, MALE) are useful for detecting surreptitious alcohol intake. Although new non-invasive methods are under development, based both on lipidomics (Owl-Liver(®)) and on biochemical determinations and anthropometric parameters (NAFLD Fibrosis score) or imaging methods (DeMILI NASH-MRi(®)), none has been proposed as definitive and the gold standard continues to be liver biopsy. The pathogenesis of alcoholic and non-alcoholic steatohepatitis shares some elements such as insulin resistance, cytochrome CYP2E1-mediated oxidative stress, adiponutrin and its PNPLA3 gene, and the microbiota. The first-line treatment consists of lifestyle changes, including giving up alcohol, diet and exercise.

Abstract
BACKGROUND Colorectal cancer (CRC) is the one of the most common malignancies and is a leading cause of cancer death worldwide. The incidence of mortality from CRC has decreased in Western countries because of earlier diagnosis and improved treatment modalities; however, mortality is still increasing in most other regions of the world. SUMMARY Progress in the development of imaging modalities has enabled more accurate staging based on the TNM classification. The therapeutic management of CRC should involve a multi-modal approach, including high-quality surgery and an optimal choice of chemotherapy and radiotherapy regimens according to disease characteristics and patient preferences. Even in the case of metastatic disease, the optimal multi-modal treatments could achieve potential cure or long-term survival benefit in some patients. The aim of this review is to present current options regarding the diagnosis, staging and treatment management for CRC based on published research reports and the current management guidelines.

[Secondary benefits of cognitive rehabilitation for a chronic ethylic patient: effects on disorder consciousness, motivation, and global therapeutic cooperation]. Encephale 2013; 40:263-70.

Abstract
INTRODUCTION Alcoholism causes psychological, behavioral and cognitive symptoms that need to be addressed together. The neuropsychological alterations among alcohol-dependent people are considered to make the therapeutic work complex and longer. A cognitive rehabilitation program is sometimes difficult to achieve with these patients. Functional results are often difficult to anticipate. However, the consequences of this therapeutic approach are multiple and there are many interactions between psycho-affective, behavioral and cognitive components. A neuropsychological approach can be used like a tool to improve metacognition. A bad contribution to treatment programs is often secondary to the illusion of a satisfying intellectual functioning. Patients' motivation for the therapeutic work is very changeable. A complete consciousness of impairments can help them to stay involved. CASE REPORT The following case shows the cognitive effects and secondary benefits associated with a neuropsychological work, which was carried out by a chronic ethylic patient with severe physical and cognitive symptoms. The patient aged 50, with a good qualification level (scientific section in the final year of secondary school, with no diploma, then attended a training program to become a croupier) was suffering from chronic alcoholism since his adolescence. He arrived in the closed unit after many hospitalizations in psychiatric and hepato-gastroenterology units. He had been showing mental confusion. He presented a frontal and subcortical profile of alcohol-related dementia according to Oslin's criteria. MRI revealed global cerebral atrophy, more pronounced on the fronto-parietal cortex with cerebellar leukoencephalopathy, but no pontine central myelinolysis. The neurocognitive program had two main lines: reducing attentional, executive and graphical deficits with training exercises (individual and group sessions) and compensating memory, and executive disorders with an external aid. The cognitive program had been assessed by means of repeated psychometric measures, behavior and metacognition estimated by direct clinical observations. The cognitive remediation was carried out during a 10-month hospitalization, and then in an outpatient rehabilitation setting over a 12-month period. The external individual sessions were associated with medical consultations and support for reintegration at home provided by the mobile psychiatric team. RESULTS The test results showed a significant improvement in attentional processes and executive functions. On graphic level, his writing was recovered after 10 months. Impairment within episodic memory processes-encoding was observed, and prospective memory was reinforced by external aids. At the end of the program, the use of an agenda proved to be effective even if updating was difficult once back home. Although a part of these effects could be expected, their psychological influence on the patient must be underlined: his perception of the alcohol related problem had been modified with more consciousness of the neurobiological consequences and a strong desire of personal implication. He worked a lot on his own (always under supervision) on cognitive exercises and succeeded in remaining abstinent for nearly 2 years. He died of complications of acute hepatitis. DISCUSSION All the cognitive assessments and rehabilitation results seem to have increased his participation in the global therapeutic care. Therapeutic tools used for cognitive work give a concrete picture of the consequences of alcohol consumption and the necessary time to retrieve brain capacities. Visible improvements in terms of reduction in disability-handicaps encouraged the patient, valued his efforts, and increased his determination to solve his alcohol related problem. Thus, cognitive programs can help to reduce passiveness and develop activeness. This patient regarded therapeutic difficulties as a challenge, not as an obstacle. We can reasonably assume the effect of the cognitive rehabilitation on the Persistence of the Cloninger's biosocial model. This increase in temperament corresponds to a certain form of tenacity, which would facilitate abstinence.

Abstract
Primary hepatic lymphoma (PHL) is a very rare malignancy and is characterized by liver involvement at presentation with no affectation of the spleen, lymph nodes, peripheral blood, bone marrow, or other tissues until at least 6 months after diagnosis. PHL should be considered in the differential diagnosis in a patient with space-occupying liver lesions and normal levels of alpha-fetoprotein and CEA. A computed tomography (CT) scan is the commonly used modality for staging lymphomas. The widespread use of positron emission tomography/CT results in the improvement in the accuracy of detecting the extent of disease, response evaluation, and prognostication. The liver biopsy, due to its pleomorphic appearances in the needle biopsy specimen, can be very challenging. Current literature favors the combination of chemotherapy as the frontline treatment for its least invasiveness and improved survival. Favorable prognosis of PHL can be obtained by early surgery combined with chemotherapy in strictly selected patients. However, the optimal therapy is still unclear and the outcomes are uncertain.

Abstract
Autoimmune liver diseases (ALD) comprise two broad categories: those with a hepatic predominance, autoimmune hepatitis (AIH), and those with a predominance of cholestatic features including primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC). An overlap syndrome (OS) is thought to exist where a patient appears with clinical features of more than one immune-mediated liver disease. Based on one personal observation we report a case of histologically proven OS. The relevant literature is briefly reviewed. A 68-year-old male was admitted in our department with general malaise, anorexia and jaundice. Trans-abdominal ultrasonography as well as computerized tomography showed a slightly enlarged liver with mild fatty deposition and the patient was submitted to transcutaneous liver biopsy. Histological features included inflammatory infiltration of intra-hepatic bile ducts with the presence of endoepithelial lymphocytes and plasma cells, degenerative distortions and even focal damage of relevant epithelial cellular structures, periductal fibrosis, portal inflammation, interface hepatitis, ductular proliferation and canalicular cholestasis. It is apparent that exact definitions pertaining the OS are limited and general consensus on the precise determinations of overlap/variant syndromes is warranted in order to enable more accurate future research and establish common guidelines in the management of the condition.
