RESUMEN
PURPOSE: The association between gout, the most common crystal arthropathy, and sexual dysfunctions has often been investigated by studies in the last decades. Despite the presence of shared risk factors and comorbidities and the possible effects on sexual health of long-term gout complications, awareness of this association is severely lacking and the pathogenetic mechanisms have only partially been identified. In the present review, we aimed to investigate the current evidence regarding the potential mechanisms linking sexual dysfunctions and gout. METHODS: A comprehensive literature search within PubMed was performed to provide a summary of currently available evidence regarding the association between gout and sexual dysfunctions. RESULTS: Gout and sexual dysfunctions share several risk factors, including diabesity, chronic kidney disease, hypertension, metabolic syndrome, and peripheral vascular disease. Gout flares triggered by intense inflammatory responses feature severe pain and disability, resulting in worse sexual function, and some, but not all, treatments can also impair sexual health. Long-term gout complications can result in persistent pain and disability due to joint deformity, fractures, or nerve compression, with negative bearing on sexual function. The presence of low-grade inflammation impairs both sex steroids synthesis and endothelial function, further advancing sexual dysfunctions. The psychological burden of gout is another issue negatively affecting sexual health. CONCLUSIONS: According to currently available evidence, several biological and psychological mechanisms link sexual dysfunctions and gout. Addressing risk factors and providing adequate treatment could potentially have beneficial effects on both conditions. Appropriate clinical evaluation and multidisciplinary approach are recommended to improve patient care.

Post-orgasmic illness syndrome (POIS) is a rare condition that includes a cluster of post-ejaculatory symptoms with debilitating physical and psychological consequences. The prevalence and incidence of POIS remain unknown as well as the pathophysiology of the syndrome, and there are no well-studied recognized treatment modalities. The current retrospective observational study describes a series of 14 highly selected patients who were actively looking for medical help as POIS has a significant effect on patients and their partners. The aim is to increase knowledge about this syndrome and possible treatment modality. According to a standard protocol, patients have been systematically interviewed, had a physical examination, laboratory blood tests, and treatments. Mean age was 34.07 ± 6.65 years. The majority of patients had only one symptom in common-extreme fatigue. The most prevalent complaints were head pressure/heaviness, nose congestion and muscle tension; all patients suffered from more than 1 symptom. POIS started on average within 30 min of ejaculation and lasted for 3.5 days. The patients reported emotional and psychosocial burden of their symptoms, which also influence their partner and relationships. Immunoglobulin-E measurements did not show elevated levels and/or significant increase within 24 h after ejaculation. Silodosin, a highly selective alpha1A-blocker, which actually causes anejaculation, was effective treatment in 57% of the patients.

Introduction: A large body of evidence has clearly documented that erectile dysfunction (ED) represents not only a complication of cardiovascular (CV) diseases (CVD) but often an early sign of forthcoming CVD.Areas covered: All the available data from meta-analyses evaluating the association between ED and CV risk were collected and discussed. Similarly, all available meta-analyses investigating the significance of ED as a possible early marker for major adverse cardiovascular events (MACE) were analyzed. In addition, data originally obtained in a Florence cohort, dealing with a large series of patients seeking medical care for sexual dysfunction, will be also reported.Expert opinion: Available evidence indicates that ED represents a risk factor of CV mortality and morbidity. Not only conventional CV risk factors but also unconventional ones, derived from a perturbation of the relational and intrapsychic domains of ED, might play a possible role in CV risk stratification of ED subjects. Finally, penile doppler ultrasound can give important information on CV risk, especially in younger and low risk subjects. The presence of ED should become an opportunity - for the patient and for the physician - to screen for the presence of comorbidities improving not only sexual health but, more importantly, men's overall health.

INTRODUCTION: In the case of primary male hypogonadism (HG), only testosterone (T) replacement therapy (TRT) is possible whereas when the problem is secondary to a pituitary or hypothalamus alteration both T production and fertility can be, theoretically, restored. We here systematically reviewed and discussed the advantages and limits of medications formally approved for the treatment of HG. AREAS COVERED: Data derived from available meta-analyses of placebo controlled randomized trials (RCTs) were considered and analyzed. Gonadotropins are well-toleratedand their use is mainly limited by higher costs and a more cumbersome treatment schedule than TRT. Available RCTs on TRT suggest that cardiovascular (CV) and venous thromboembolism risk is not a major issue and that prostate safety is guaranteed. The risk of increased hematocrit is mainly limited to the use of short terminjectable preparations. EXPERT OPINION: In the last few years the concept of 'organic' irreversible HG and 'functional' or age- and comorbidity-related HG has been introduced. This definition is not evidence-based. The majority of RCTs enrolled patients with 'functional' HG. Considering the significant improvement in body composition, glucose metabolism and sexual activity, TRT should not be limited to 'organic' HG, but also offered for 'functional'.

Androgen deficiency syndrome is a commonly diagnosed condition. The aim of this study was to investigate common clinical practices of specialists in the field of sexual medicine regarding androgen replacement treatment for men and women. Attendees of the 16th Annual Congress of the European Society of Sexual Medicine held in January 2014 in Istanbul, Turkey, were asked to participate in a survey during the congress days. A 24-item self-report, closed-question questionnaire was distributed. Three sections were accessed: sociodemographic data, professional background and personal practice patterns regarding androgen substitution in men and women. A total of 133 physicians (mean age 47 years; range 25-79) completed the survey. Responses were inconsistent regarding the lab tests used for primary evaluation of male androgen deficiency. The majority of participants (62%) recommended testosterone replacement therapy for symptomatic men with testosterone levels <8 nmol l(-1) (231 ng dl(-1)). Similarly, most physicians (88%) recognized a correlation between libido and testosterone levels in women. Only 42% and 53% reported they would prescribe testosterone to women with low libido, premenopausal and postmenopausal, respectively. This survey showed discrepancies among physicians regarding testosterone replacement therapy for men and women.

Low-intensity shockwaves (LISW) are known to produce revascularization and have been in evaluation and in use to treat erectile dysfunction (ED). The present single-arm pilot study is aimed to assess the safety and efficacy of a dedicated shockwave device (Renova) on vasculogenic ED patients. Fifty-eight patients with mild to severe ED were treated by LISW and their erectile function was evaluated by the International Index of Erectile Function-Erectile Function Domain (IIEF-EF), Sexual Encounter Profile and Global Assessment Questions questionnaires, at baseline and at 1, 3 and 6 months post treatment. The average IIEF-EF increased significantly from 14.78 at baseline to 21.93 at 3 months post treatment and stabilized at 22.26 at 6 months post treatment. Out of 58 patients, 47 (81%) had a successful treatment. No adverse events were reported during the treatment and the follow-up duration. In conclusion, it suggests that the performance of LISW could add a new advanced treatment for ED.

A metastasis from a renal cell carcinoma to a seminal vesicle is extremely rare. This pattern of metastatic disease has been reported once previously in the Japanese literature. We describe a patient with irritability symptoms of the urine bladder and involuntary loss of stool caused by obstruction of the bladder by a large metastasis from a renal cell carcinoma to the seminal vesicle. The mode of diagnosis and treatment of this patient are described.

High-flow priapism is characteristically diagnosed on clinical findings: a prolonged, non-painful erection with a delayed onset that develops after a penile or perineal trauma. If conservative measures fail arteriography is indicated, which shows a blush of extravasating contrast from an arterio-cavernous fistula (rarely, as in our case bilateral) that can be treated by embolization. The embolic agent is gelfoam or a microcoil. Bilateral embolization is indicated when unilateral treatment does not result in detumescence of the penis. When the embolization is done highly selective the risk of complications is low and the results on erectile function are good.

BACKGROUND/AIMS: One of the prognostic methods for survival in primary biliary cirrhosis (PBC) is the Mayo model, with a time-scale limited to 7 years. The aim of our study was to assess how major clinical events, signs, several severity assessment methods and Mayo survival probabilities fit in with actual patient survival, by using yearly observations until 0.5 years before patient death from PBC. METHODOLOGY: Data of 32 patients dying from PBC were collected prior to death at -0.5, -1, -2 etc. years (median: -5 years, range: -16 to -0.5 years). Major events registered were: first occurrence of ascites, upper gastrointestinal bleeding or manifest hepatic encephalopathy and signs, first observation of spider naevi or purpura. Severity assessment methods applied (all with scores and classes) were: Mayo (M), Child-Campbell (C), Pugh-Child (P), Pugh-Child-PBC (PP), 'Child-Pugh' (CP), and Ascites Nutritional State-Child (ANS). Fifty percent survival estimates were calculated from Mayo scores. Severity assessment method variables were: ascites (C, P, PP, CP, ANS), encephalopathy (C, P, PP, CP), nutritional state (C, ANS), edema (M), age (M), serum albumin (M, C, P, PP, CP), bilirubin (C, M, P, PP, CP), and prothrombin time (M, P, PP, CP). RESULTS: In 27 out of 32 patients a major event occurred, always between -6 and -0.5 years (median: -1 year) and, never between -16 and -7 years (p < 0.0001). A sign was first observed in 30/32 between -14 and -0.5 years (median: -2 years). Compared to the total population, a sign, and even more so, an event indicated a shorter survival (p = 0.004 and p = 0.0002, respectively). The median 50% estimated survival (predicted by the Mayo model) fitted the actual survival from -6 to -0.5 years (r = -0.7, p < 0.0001), but not from -16 to -7 years (r = -0.1, p = 0.4). All -6 to -0.5-year severity scores correlated (p < 0.0001) both with actual survival (M, C, P, PP, and CP r = 0.7; ANS r = 0.5) and with estimated M 50% survival (C, P, PP, CP r = -0.9; ANS r = -0.6; M score: -0.99), but none with actual survival from -16 to -7 years, except for M, slightly (r = -0.3, p = 0.04). A nomogram for mean C, CP, M and ANS scores related to actual survival was constructed for the -6 to -0.5-year period. The C and CP classes A, B, and C did not appear to distinguish sufficiently into actual survival, whereas the M classes did. CONCLUSIONS: The occurrence of a major event appeared to exclude survival over 6 years. In these final 6 years, Child-Campbell, Mayo and Pugh scores correlated equally well with actual survival and better than Ascites/Nutritional State score. In our PBC patients, Campbell was an excellent alternative for Pugh; for Pugh, the original Child-Turcotte variable limits were fully sufficient.

To examine the effect of patient's age and the location of diverticular disease on the course of the acute disease we retrospectively collected demographic data, symptoms, laboratory findings, imaging techniques, type of treatment (conservative vs. surgical), early and late complications, and follow-up data on 119 patients with acute diverticulitis (74 women, 45 men; mean age 64+/-14 years; follow-up 7-102 months, median 40). Patients were divided by their age into two groups (42 aged 60 years or younger, 77 aged over 60) and on the location of their disease (108 to the left of the middle transverse, 11 to the right). Lower abdominal pain, abdominal tenderness, and fever were the most common complaints (70-97%). In the younger patients we found a significantly greater preponderance in the right colon (P = 0.02) than in older patients. Abdominal abscesses and fistulas were more common in right-sided diverticulitis (P = 0.01). Patients with right-sided colon diverticulitis were treated surgically (82%) and on an emergency basis more often than patients with left-side colon diverticulitis (25%; P = 0.001). Older patients treated conservatively suffered more than younger patients (61% and 33% respectively; P = 0.04) from recurrent abdominal pain but not from recurrent, confirmed diverticulitis. Patients with right-sided diverticulitis treated conservatively suffered more from recurrent diverticulitis episodes than patients with left-sided diverticulitis (P = 0.05). Younger patients thus do not have a more aggressive form of diverticulitis than older patients. Patients with acute diverticulitis in the right colon are likely to be operated earlier and for mistaken diagnoses than patients with left-sided diverticulitis.

BACKGROUND/AIMS: The assessment of disease stage in cirrhosis is important for the individual patient (prognosis, timing and risk for requiring surgical intervention) and also for population comparisons and trials. There are several established methods, and we have aimed at comparison of the methods within a large cirrhosis population. METHODOLOGY: In the European Union Euricterus database, there are 1015 patients with a "certain" diagnosis of cirrhosis, each of whom in one session had a protocol work-up of history, physical examination and all laboratory investigations needed for this study. The Child-Turcotte (CT), Campbell-Child (C) and Pugh-Child (P) classifications, as well as ascites/no ascites, ascites 1, 2, 3 (no, therapy responsive, nonresponsive) and ascites/nutritional state (ANS, 1-9) scores were used. CT and C have the same 5 variables, P has prothrombin time instead of nutritional state. CT, C and P variables score 1-3 each. C and P furthermore have variable range scores of 5-15. CT, C and P have classes A-C. The variables used were ascites, nutritional state, encephalopathy, bilirubin, albumin and prothrombin time. RESULTS: Only 53 patients (5%) fit within the CT criteria. C and P variable range scores (5-15) correlated strongly (r = 0.84). Cross-over calculation showed slightly different results in the P and C choice of variables, while the variable ranges (1-3) did not matter. Different selection of score ranges for the A-C classes in C and P resulted in 69% class C in P (35% in C) and 3% A in P (19% in C). The patients with ascites (70%) had worse bilirubin, albumin, nutritional states and C and P 5-15 scores (p < 0.0001). Patients with ascites 3 had all variables and also C, P 5-15 scores worse than those with ascites 2 (p < 0.02). ANS scoring showed wasting in 33% of the patients without ascites (ANS 3), 50% of the patients with ascites 2 (ANS 6) and 60% with ascites 3 (ANS 9) (p < 0.0003), and C and P scores were higher in the 3 ANS scores with wasting. CONCLUSIONS: Campbell and Pugh 5-15 scores correlated closely and can be used interachangeably. As C does not contain the more elaborate prothrombin time determination, it probably can be used anywhere in the world. Ascites (degree) and Ascites/Nutritional State (ANS) scoring only use history and physical examination and are, or remain, although less refined, clinically relevant.

BACKGROUND/AIMS: In the European Union Euricterus Project on (sub)Icterus proforma, the history and physical examination items were to be used for the physician's working diagnosis (PWD) and 'among others, for the development of the real life data electronic diagnostic tool, Trial. Trial delivers diagnosis probabilities based on Bayes' Theorem (B), completed by Trial Algorithm (TA). We wanted to compare the diagnostic accuracies (PWD and Trial probabilities as a percentage of the final diagnosis (FD) in a patient population) in 3 Dutch databases. METHODOLOGY: The inclusion criteria for both Euricterus and Trial were age > or = 16 and bilirubin > or = 20 mmol/l. Euricterus data gathering took place at the bedside on a proforma with (among other questions) 79 questions on history and physical examination as well as the diagnosis levels for the PWD (1 alternative possible) and FD (17 disease categories, dc). Trial was developed on the data of 7,104 Euricterus patients and its data-entry Demo has the same questions. It calculates the probability of each diagnosis of the 17 dc as a percentage, as each significant finding is encountered (BO, Bayesian Overall). It can simultaneously calculate the resemblance of the patient's signs and symptoms to each disease concomitantly (BV, Bayesian Vertical), and to any subset of a disease. Any probability is further tested for compatibility using TA, a subset of BV, delivering TA-PWD, TA-BO and TA-BV. The Trial test patients came from 3 databases: a Euricterus Dutch Patients Random Sample EDRS (n = 184, internal database) and 2 independent databases: prospective P (n = 80) and retrospective R (n = 152), totalling 416 patients. RESULTS: The accuracies of PWD and Trial showed no differences between the databases, and the results are therefore pooled (n = 416). With testing on the highest probability found, the PWD accuracy was 78%, TA-PWD 81%, TA-BO 74% and TA-BV 72%. The true FD's were mentioned (at any probability) in the PWD in 86%, TA-PWD in 92%, TA-BO in 94% and TA-BV in 91% of the patients. Testing only patients whose FD was "certain" or whose data were without omissions did not improve accuracy. Testing on probability > 95% improved BO and BV accuracy, but not TA-BO or TA-BV. CONCLUSIONS: The Physician's Working Diagnosis accuracy was approximately 80% and did not greatly improve after TA. The Trial TA-BO and TA-BV accuracies were only slightly less than the PWD. For well-trained physicians, Trial strengthens the physician's judgment, and for those less trained (or those to be trained), it delivers a (sub)icterus diagnostic disease probability at nearly consultant level.

BACKGROUND/AIMS: Estimation of prognosis becomes increasingly important in primary biliary cirrhosis (PBC) with advancing disease and also with regard to patient management. The ubiquitous used Pugh scoring for severity of disease is simple while the Mayo model which has been validated for survival estimates is more sophisticated. We wanted to investigate whether Pugh and Mayo scores correlate (they have 3 of 5 variables in common) and if so whether a survival probability based on Mayo data could be affixed on Pugh classes and scores obtained in the same patients. METHODOLOGY: All variables used for Mayo Clinic Prognostic Model (Mayo) scoring and Pugh-Child-PBC (Pugh) scoring were available in 143 PBC patients of the Pan European database Euricterus. Pugh scores P5-P15 and has classes A (P5-6), B (P7-9) and C (P10-15). We subdivided P5 in P5A (patients with albumin > 40 g/l plus prothrombin time < or = 12 secs) and P5B (the other patients in P5). We designed a category Pugh Early (PE) for patients with P5A characteristics and bilirubin < 17 mmol/l. Mayo scores R0-R15-with 1-7 years survival probabilities S-and has risk classes Low (L), Intermediate (Int), High (H) and Very High (VH). RESULTS: The estimated survival probabilities of the 143 patients ranged from 88% at 7 years to 0% at 1 year, median 14% at 5 years. The Pugh and Mayo scores correlated r = 0.87 (p < 0.0001) and except age with P, all Mayo and Pugh variables correlated with both R and P at p < 0.0001. Survival in Pugh class A was median 43% at 7 years and was not different from survival in Mayo L+Int (p 0.58). In Pugh class B 7 years survival was 2%, not different from Mayo H (p 0.25). Survival in Pugh C was median 24% at 1 years and better than Mayo VH (p 0.02). Between P5A (survival 78% at 7 yr) and R 3-4; P5B-6 (40% at 7 yr) and R5; P7 (22% at 7 yr) and R6; P8-11 (12% at 5 yr) and R7-8; and P12-14 (5% at 1 yr) and R9-10 no significant differences were found. From P8 upward there was a steep increase in death rate. PE has a 7 year survival of at least 89%. Charts of projected survival estimates for Pugh scores and classes are presented. CONCLUSION: It was possible (affixing Mayo to Pugh) to define 1-7 years survival probabilities to Pugh classes and scores for the last 7 years of the disease, i.e. the most important period for therapeutic decisions. These results need to be validated in other PBC populations.

BACKGROUND/AIMS: Primary Biliary Cirrhosis (PBC) is a relatively rare chronic progressive disease in which a working diagnosis of PBC easily leads to a final diagnosis by testing for anti-mitochondrial antibodies. Liver transplantation is the only effective treatment. The aim of this study was to test an electronic diagnostic tool (tool) for it's ability to include PBC in the working differential diagnosis. METHODOLOGY: In the European Union Euricterus project a large number of (sub)icteric patients in 17 discrete disease categories, PBC being one of them, were gathered prospectively. A tool was developed-using Bayes (B) and Trial Algorithm (TA) pattern-recognition and based on items related to the history, symptoms and signs of all Euricterus patients. We have tested the diagnostic tool on 143 PBC Euricterus patients. RESULTS: PBC was mentioned by the tool in 86% (B) and 91% (TA) of the 143 patients. These figures were higher for patients under 60 and (TA only) females. Females under 60 (n = 89) scored 92% B and 96% TA. A sole diagnosis of PBC was made in 31% (B) and 66% (TA). In the other patients with a PBC probability, 7 other (first) diagnoses were presented by the tool of which non-alcoholic active liver disease and pancreatic or biliary carcinoma were the leaders. These 7 diseases appeared evenly distributed along the percentual probabilities of PBC given by the tool (B) and also along Pugh and Mayo scores (B and TA). PBC was mentioned by the tool in all patients with a Pugh score 10 or higher (advanced disease, class C). In the patients in whom the tool did not mention PBC, the primary diagnoses came from 9 other disease categories. CONCLUSION: This electronic tool has been able to identify PBC as one of the differential diagnostic modalities in the large majority of a present population of PBC patients.

BACKGROUND: From a primary clinical database, we wanted to obtain insight in disease distribution and clinical presentation of adult jaundiced patients in a Western country. MATERIALS AND METHODS: As part of the Euricterus project, 24 Dutch general and academic hospitals in a period of 2 years gathered prospectively 702 patients on a standard proforma. Patient aged 16 years or more (median 61) and with a serum bilirubin of 20 mmol/l or more (median 83) were included. The final diagnosis was established within 3 months. RESULTS: Pancreatic or biliary carcinoma (20%), gallstone disease (13%) and alcoholic liver cirrhosis (10%) were the 3 most frequent diagnoses. Imaging (79%), clinical course (63%) and chemistry/serology (57%) were the most used ascertaining methods. Pancreatic or biliary carcinoma and gallstone disease were more common and age higher in general hospitals (p = 0.0001), and 'immunological' liver disease, non-alcoholic cirrhosis and hepatocellular carcinoma (HCC) more common in academic hospitals (p = 0.001). Patients aged 90 years or older (13%) had pancreatic or biliary carcinoma, liver metastases or heart failure and patients with age less than 20 (0.9%) had acute viral hepatitis, nonalcoholic active liver disease or HCC. Risk factors were more apparent (p < 0.02) in those aged less than 61 years. Feeling unwell (78%), dark urine (67%) and anorexia (57%) were the 3 most frequent symptoms; the 3 most frequent signs were liver enlarged (39%), looking ill (29%) and appearing wasted (23%). CONCLUSIONS: Through Euricterus, fresh clinical knowledge has emerged of symptomatology, age stratification and hospital preponderance of (sub)clinical jaundice in this country. This is important both for teaching and in preparing clinical studies.

Presentations of acute systemic weakness are rare and appear dramatic and frightening to both patients and physicians. Aetiologies are multifactorial and diverse. Morbidity and mortality are associated with the unrecognized disease. One of the underlying disorders is hypokalaemic thyrotoxic periodic paralysis (HTPP), an uncommon disorder. HTPP is characterized by periodic occurrences of muscle weakness during attacks of hyperthyroidism and appears predominantly in Orientals. This article describes a patient of Chinese origin with hyperthyroidism and attacks of paralysis and considers several problems: a lack of familiarity with the syndrome, increasing numbers of patients with this disease in European hospitals as a result of migration of populations, and the importance of patient compliance in therapeutic management. Finally, a review of the literature concerning presentation, differential diagnosis, pathophysiology, and therapeutic management is provided.

During the last three decades a great deal of research has been devoted to the development of integrated clinical decision support systems. This report aims to give a basic understanding of what is required for such a system. By means of a large literature study a survey is given of the major components of computer-based clinical aid systems. The main approaches and several aspects of evaluation of such programs are described. The computer has several inherent capabilities which are suitable for medical problem solving and can help in the formalization of medical knowledge. The components of such systems include the computer database, the reasoning engine and the user interface. The different approaches on which the reasoning engine is built are based on manipulation of information and advocate the use of knowledge to construct a solution to a problem. The information in the mode vary from data-intensive to knowledge-intensive. Assessment of decision support systems is a very important phase in the development of such systems. Evaluation should be made on the accuracy of the program, the nature of the system, the use of the data and the acceptance by the target users. Whatever the model is, its effectiveness will depend on the data with which the program has to work. Acceptance by physicians depends among other things on ease of use of the user interface. Profound changes in the delivery of health care will be induced through the rapid growth of on-line computer communication together with the development of integrated clinical decision support systems and electronic medical records. Notwithstanding the rapid growth of computer technology, computer-aided decision making is in its infancy and real support in daily practice is not yet achieved.
