    Anorectal emergencies refer to anorectal disorders presenting with some alarming symptoms such as acute anal pain and bleeding which might require an immediate management. This article deals with the diagnosis and management of common anorectal emergencies such as acutely thrombosed external hemorrhoid, thrombosed or strangulated internal hemorrhoid, bleeding hemorrhoid, bleeding anorectal varices, anal fissure, irreducible or strangulated rectal prolapse, anorectal abscess, perineal necrotizing fasciitis (Fournier gangrene), retained anorectal foreign bodies and obstructing rectal cancer. Sexually transmitted diseases as anorectal non-surgical emergencies and some anorectal emergencies in neonates are also discussed. The last part of this review dedicates to the management of early complications following common anorectal procedures that may present as an emergency including acute urinary retention, bleeding, fecal impaction and anorectal sepsis. Although many of anorectal disorders presenting in an emergency setting are not life-threatening and may be successfully treated in an outpatient clinic, an accurate diagnosis and proper management remains a challenging problem for clinicians. A detailed history taking and a careful physical examination, including digital rectal examination and anoscopy, is essential for correct diagnosis and plan of treatment. In some cases, some imaging examinations, such as endoanal ultrasonography and computerized tomography scan of whole abdomen, are required. If in doubt, the attending physicians should not hesitate to consult an expert e.g., colorectal surgeon about the diagnosis, proper management and appropriate follow-up.

    Men who have sex with men have special health-care issues and are at high risk for sexually transmitted infections. In managing their anorectal health it is important to modify the history and physical and handle patients in a nonjudgmental fashion. It is important to understand behavioral patterns including recreational drug use, unprotected sex, and HIV infection. Screening and counseling play important roles in effective management of these patients.

    3D-high definition anorectal manometry (3DARM) may aid the diagnosis of functional anorectal disorders, but data comparing asymptomatic and symptomatic subjects are scarce. We aimed to describe 3DARM values in asymptomatic volunteers and those with fecal incontinence (FI) or chronic constipation (CC), and identify which variables differentiate best these groups. Asymptomatic subjects were stratified by sex, age, and parity. Those with FI or CC were included according to anorectal symptom questionnaires. Endoanal ultrasound examination and 3DARM were performed the same day. Anal pressures were analyzed at rest, during voluntary squeeze, and during push maneuver, and compared between the 3 groups. Anal pressure defects were defined and compared to ultrasound defects. A total of 126 subjects (113 female, mean age 52 years, range 18-83) were included; 36 asymptomatic, 38 FI, 42 CC. Anal resting and squeeze pressures, and rectal sensitivity values were lower in FI women than in the other groups. Typical anal sphincter asymmetry during squeezing was less frequently observed in FI women. A dyssynergic pattern during push maneuver was found in 70% of asymptomatic subjects, and with a similar frequency in the 2 symptomatic groups. There was slight concordance between 3D-pressure defects and ultrasound defects. 3D anal pressures in asymptomatic women were significantly lower than in men, and in FI compared to asymptomatic women. The classical dyssynergic pattern during push maneuver was found as frequently in asymptomatic and symptomatic patients. Further studies should try to identify 3DARM variables that could reliably identify dyssynergic defecation. © 2017 John Wiley & Sons Ltd.

  5. Ano-Rectal Symptoms of Sexually Transmitted Disease

    Diseases of the anus and rectum are frequently the outcome of proctogenital and oral-anal sexual activities. These sexually transmitted diseases are more common among homosexual and bisexual men than among heterosexuals. A variety of infectious agents are responsible including viruses, bacteria, spirochetes, helminths, and protozoa. Anal warts, herpetic ulcers, and syphilitic chancres are common anal STDs. Gonorrhea, herpes, and chlamydial organisms are common causes of venereal acute proctitis. Enteric infections such as shigellosis, amebiasis, giardiasis and pinworms can be transmitted by oral-anal contact. Aggressive sexual attempts at auto-eroticism using rectally inserted foreign bodies may cause traumatic proctitis complicated by bacterial peritonitis or perirectal abscesses. PMID:21263807

    In January 2004 the European Surveillance of Sexually Transmitted Infections Network (ESSTI) issued an international alert regarding an outbreak of Lymphogranuloma venereum (LGV) in Rotterdam in a sexual network of men who have sex with men (MSM). Further to this alert, a retrospective survey was set up by the Institut de Veille Sanitaire and the reference laboratories for N.gonorrhoeae and Chlamydia in France. Our STI clinic in Paris carried out a clinico-biological retrospective study involving 154 MSM screened for anorectal sexually transmitted infections (STIs) between January 2002 and May 2004 and a prospective study between May 2004 and August 2004. Out of 216 swabs of rectal discharge from homosexual or bisexual males, a total of 32 were positive for C. trachomatis (14.8%) (3 patients in 2002, 11 in 2003 and 18 in 2004). C. trachomatis-positive rectal strains were genotyped to detect the specific C. trachomatis serovars and revealed serovars L(2) for 22 patients (respectively 1 in 2002, 9 in 2003 and 12 in 2004). Serum antibody titers for Chlamydia trachomatis were determined among 14 subjects and revealed strongly positive in 13 cases (1/512 to 1/16384) titers of IgG. These 22 patients with clinico-biologically confirmed anorectal lymphogranuloma venereum (ARLGV) were all homosexual men. They ranged from 28 to 52 years (mean age 39.2 years). 12 of 21 (57.1%) subjects with an ARLGV diagnosis were seropositive for human immunodeficiency virus (HIV) (one not done). Although rare, anorectal lymphogranuloma venereum (ARLGV) still exists in France and should not be forgotten in the differential diagnosis of rectal problems in male homosexuals.

    The purpose of this study is to evaluate normal values and pressure morphology of three-dimensional high-resolution anorectal manometry (3D-HRM) in asymptomatic volunteers and to determine the relationship between objective measurable values, gender, and age. Anorectal pressures and rectal sensation were evaluated in 110 asymptomatic volunteers (46 females and 64 males) ranging in age from 18 to 80 years (median age, 52 years) in left lateral position by three-dimensional high-resolution manometry. Maximum squeeze pressure, residual anal pressure, and intrarectal pressure were significantly higher in males compared to females (p < 0.05 each). Duration of sustained squeeze was significantly lower in males compared to females (p < 0.05). Maximum resting pressure, mean resting pressure, and maximum squeeze pressure were inversely correlated (r = -0.310, p < 0.01, r = -0.276, p < 0.01, and r = -0.198, p < 0.05) with age. The value of rectoanal pressure differential was -13.1 ± 5.8 mmHg which was negative during defecation. Overall variation coefficient in anorectal pressures ranged between 0.21 and 0.34. This study establishes normal values for anorectal pressure by 3D-HRM in asymptomatic volunteers. There are significant gender differences concerning squeeze patterns. Increasing age is associated with lower maximum resting pressure, mean resting pressure, and maximum squeeze pressure. Normal characteristic pressure morphology of anorectum can be obtained at rest, during squeeze, and bear down as in defecation by 3D-HRM.

    Homicides exclusively due to genital trauma have not been widely reported, and anorectal trauma in sexual assaults is uncommon. We describe a case of a 45-year-old white woman who sustained devastating homicidal colorectal trauma that served as a primary cause of death in the setting of rape. Our patient sustained a 15-cm laceration of the anterior rectal wall and ultimately died of peritonitis and sepsis. Death from rectal perforation and sepsis in the setting of sexual assault is rare and has only been documented in 3 other cases, 2 pediatric patients and 1 elderly debilitated patient. Other representative and unique methods of perforation are reviewed along with a brief discussion of the development of peritonitis after perforating colorectal trauma.

    The results of analysis of 46 commission forensic medical expertises are presented based on the materials concerning injuries and changes in the anorectal region and rectum unrelated to attempts at sexual abuse. The materials were collected and stored by the Primorskoye territorial Bureau of forensic medical expertise during 5 years, from 2005 to 2009. All injuries and changes were categorized into several groups in terms of their origin, viz. car accidents, inadequate medical care, insertion of foreign bodies, falls on sharp and protruding objects, gunshot wounds, chemical and thermal burns, sports training, etc. The occurrence of the injuries is illustrated by the examples from forensic medical practice. It is concluded that experts describing injuries and changes in the anorectal region and rectum must act in conformity with the order of the Russian Ministry of Health No 346 dated October 21, 2010) and use instrumental methods and terminology accepted in modern proctology. The severity of harm to health in subjects presenting with injuries and changes in the anorectal region and rectum should be evaluated in terms of both the degree of the threat to life and the outcome of the treatment with special reference to the duration of health impairment, severity of the trauma, and its consequences (anorectal dysfunction).

    Objectives To demonstrate the value of routine, basic sexually transmitted infection (STI) screening at enrolment into an HIV-1 vaccine feasibility cohort study and to highlight the importance of soliciting a history of receptive anal intercourse (RAI) in adults identified as ‘high risk’. Methods Routine STI screening was offered to adults at high risk for HIV-1 upon enrolment into a cohort study in preparation for HIV-1 vaccine trials. Risk behaviors and STI prevalence were summarized, and the value of microscopy assessed. Associations between prevalent HIV-1 infection and RAI or prevalent STIs were evaluated with multiple logistic regression. Results Participants had a high burden of untreated STIs. Symptom-directed management would have missed 67% of urethritis cases in men and 59% of cervicitis cases in women. RAI was reported by 36% of male and 18% of female participants. RAI was strongly associated with HIV-1 in men (adjusted odds ratio [aOR] = 3.8, 95% CI 2.0 – 6.9), and independently associated with syphilis in women (aOR 12.9, 95% CI 3.4 – 48.7). Conclusions High-risk adults recruited for HIV-1 prevention trials carry a high STI burden. Symptom-directed treatment may miss many cases, and simple laboratory-based screening can be done with little cost. Risk assessment should include questions about anal intercourse and whether condoms were used. STI screening, including specific assessment for anorectal disease, should be offered in African research settings recruiting participants at high risk for HIV-1 acquisition. PMID:18375645

    The aim of the German Network for Congenital Uro-REctal Malformations (CURE-Net) is to collect data of affected patients with anorectal malformation (ARM) to investigate molecular causes, clinical implications and psychosocial outcome. The current issue was to examine sexual function and to explore psychosocial adaptation in adults with ARM. This qualitative study using narrative inquiry is part of a larger multi-center study of clinical queries and quality of life in patients with ARM. The guided interview focused on analysis of sexual function. 55 adult patients with ARM (23 females, 32 males, median age 23 years, range from 18 to 56 years) were investigated via standardized case-report forms comprising interview, analysis of medical data and personal questionnaires. In the female patients, 8 (35 %) of them lived alone and 15 (65 %) had sexual intercourse. In the male patients, the majority of 20 (69 %) patients lived alone and 13 (45 %) had sexual intercourse. 6 of the females got pregnant, 5 got 2 or more children. 3 of the men induced 2 or more pregnancies and fathered children. Besides reconstructing the ARM, another main goal is the preservation of sexual function. According to our data, there seems to be a close relationship between psychosocial development and sexual activity.

    Anorectal malformations comprise a wide spectrum of diseases, which can affect boys and girls, and involve the distal anus and rectum as well as the urinary and genital tracts. They occur in approximately 1 in 5000 live births. Defects range from the very minor and easily treated with an excellent functional prognosis, to those that are complex, difficult to manage, are often associated with other anomalies, and have a poor functional prognosis. The surgical approach to repairing these defects changed dramatically in 1980 with the introduction of the posterior sagittal approach, which allowed surgeons to view the anatomy of these defects clearly, to repair them under direct vision, and to learn about the complex anatomic arrangement of the junction of rectum and genitourinary tract. Better imaging techniques, and a better knowledge of the anatomy and physiology of the pelvic structures at birth have refined diagnosis and initial management, and the analysis of large series of patients allows better prediction of associated anomalies and functional prognosis. The main concerns for the surgeon in correcting these anomalies are bowel control, urinary control, and sexual function. With early diagnosis, management of associated anomalies and efficient meticulous surgical repair, patients have the best chance for a good functional outcome. Fecal and urinary incontinence can occur even with an excellent anatomic repair, due mainly to associated problems such as a poorly developed sacrum, deficient nerve supply, and spinal cord anomalies. For these patients, an effective bowel management program, including enema and dietary restrictions has been devised to improve their quality of life. PMID:17651510

    Minimally invasive surgery for pelvic floor prolapse has recently been shown to be feasible and safe. This study presents the results of robotic-assisted and laparoscopic rectopexy for complex rectocoele, focusing on less frequently reported outcomes of bowel and sexual function. We prospectively assessed 41 consecutive patients who underwent ventral mesh rectopexy (robotic-assisted or laparoscopic) for a symptomatic complex rectocoele from January 2009 to January 2010. Complex rectocoele was defined as having one or more of the following features: larger than 3 cm, an enterocoele or internal rectal prolapse. Patients with cystocoele underwent bladder suspension concurrently. Both groups were assessed for anatomical recurrence and function, comparing preoperative and postoperative faecal incontinence, obstructive defaecation syndrome and Gastrointestinal Quality-of-life Index scores, as well as vaginal discomfort and sexual function. Forty-one women underwent the procedure (16 robotic-assisted), with four (10.5%) having minor complications and two developing anatomical recurrence. There was significant relief of the commonest predominant symptoms of vaginal bulge/fullness (P<0.0001) and sexual dysfunction (P=0.02). There were three conversions to laparotomy (one robotic-assisted) and five patients declined postoperative functional assessment. In the remaining 33 patients [follow-up median 12 (8-21) months], analysis revealed no significant difference in overall functional score (P>0.740) or between patients with one or two meshes inserted (P>0.486). Only patients with a preoperative obstructive defaecation syndrome score >6 had a significant improvement postoperatively (P=0.030). Minimally invasive ventral mesh rectopexy for complex rectocoele offers satisfactory anatomical correction and functional results, with the potential for alleviating symptoms of outlet obstruction and improving vaginal comfort and sexual dysfunction. © 2011 The Authors.

    Background: Men who have sex with men (MSM) are disproportionately affected by sexually transmitted infection. The aim of this cross-sectional study is to prospectively detect the prevalence of chlamydia trachomatis (CT), neisseria gonorrhoeae (NG), mycoplasma genitalium (MG), and high risk human papillomavirus (HR-HPV), and syphilis in a population of asymptomatic sexually active MSM. Methods: Rectal, pharyngeal, and urine samples for CT, NG, MG, and HR-HPV were analyzed in 116 MSM patients attending the clinic for their routine follow-up during the period the study was conducted: 99 patients were issued from the clinic routine follow-up for their HIV infection, and 17 attended the clinic because they were sexual partners of an HIV infected male. Results: An STI was found in 16% of the patients (19/116), with at least one bacterial strain (CT, NG, or MG) found in one site (the pharynx, rectum, or urine). Conclusions: In this study, 16% of the MSM reporting recent RAI were asymptomatic carriers of rectal CT, NG, or MG. According to the high prevalence of asymptomatic STIs found in our MSM population and in other studies, prevention efforts in the form of counseling about the risk of STI need to be done in the population of MSM.

    To examine lymphogranuloma venereum (LGV) trends over time among men who have sex with men (MSM) visiting the Amsterdam sexually transmitted infection (STI) clinic; to investigate anal LGV symptomatology; and to examine the positivity and characteristics of anorectal and inguinal LGV. We included MSM consultations from whom a swab (from anorectum, bubo or an genital ulcer) was taken for Chlamydia trachomatis (Ct) screening. Anorectal swabs were taken from all MSM who reported receptive anorectal intercourse in the preceding 6 months. Ct positive samples were further tested with a pmpH PCR to identify L-genovars. Patient symptoms, clinical and anoscopic inflammatory signs, and STI co-infections were noted; Gram-stained anorectal mucosal smears were examined. Between January 2005 and June 2012, 48 570 consultations among MSM were conducted. In 3628/35 650 visits, anorectal Ct infections were diagnosed, including 411 anal LGV (1.2%). Moreover, 65/1649 genital ulcer swabs were Ct positive; 10 were inguinal LGV (0.6%) Since January 2011 a significant increase in the positivity of LGV occurred (p<0.0001). 89 (27.2%) anorectal LGV cases were asymptomatic. HIV prevalence among anorectal LGV cases was significantly higher (p=0.008) than among inguinal LGV cases. STI co-morbidity in anorectal LGV cases remained invariably high during the study period. Since January 2011, LGV positivity in MSM consultations in Amsterdam has risen significantly. The great majority comprise anal LGV; inguinal LGV is rare. Anal LGV is asymptomatic in a quarter of cases. In all MSM with anal Ct infections LGV should be excluded, irrespective of symptoms or inflammatory signs.

    Control strategies for Chlamydia trachomatis (CT) are most effective when targeting people at highest risk. We assessed test acceptance of home-collection test kits offered by short messaging services (SMS) texts, in high-risk young people, i.e. those who had previously tested CT positive (positive indices), or negative reporting more than 3 sex partners (negative indices), and their sexual and social networks. Young (16 to 25 years old) heterosexuals who previously tested positive (n=536) or negative (n=536) in our STI clinic received, 3 to 20 months after their initial screening, an SMS inviting them to re-test. They were offered a free home-collection test kit including a genital (men and women) and anorectal (women only) test, and a test kit to pass on to a friend or sex partner (peer). SMS reminders were sent in case of non-response. We assessed proportions of tests requested and returned, peers tested, and positivity. Associations with the individual's initial screening result and other factors were explored using logistic regression. Of 1072 people invited to retest, 34.4% (n=369) requested a test. Of these, 55.8% (n=206) retested. Overall, retest participation was higher in positive (22%) than in negative indices (16%) (p<0.001); it was also higher in women and in those aged >22 years. Positivity was 13% and 7% in positive and negative indices, respectively. One in 3 retesters also had a peer tested. Of tested peers (n=87), 84% were friends, 31% were first-time testers, and 7% tested positive. Acceptance of a relatively low-cost strategy for genital and anorectal testing, i.e. using SMS and home-collection test kits, was highest in individuals who previously tested CT positive suggesting that implementation for this group may be considered. By further including a peer-led testing component, undetected CT positives can be identified in the social networks surrounding a high-risk individual.

    Sexually transmitted diseases (STD) are a major health problem affecting mostly young people in both developing and developed countries. STD in women causes both acute morbidity and complications such as infertility, ectopic pregnancy, low-birth weight, and prematurity. The aim of the study is to assess the prevalence of bacterial vaginosis, vaginal candidiasis, and trichomoniasis among asymptomatic females attending STD outpatient department in a tertiary care hospital in South India. A retrospective analysis of data collected from clinical records of 3000 female patients of age 18 to 49 over a period of 12 months (July 2014 to June 2015) was carried out at the Institute of Venereology, Madras Medical College. Complete epidemiological, clinical, and investigational data were recorded and analyzed for the prevalence of bacterial vaginosis, vaginal candidiasis, and trichomoniasis among asymptomatic patients. About 48.37% (228/470) of bacterial vaginosis patients were asymptomatic. Nearly 45.38% (116/235) of vaginal candidiasis patients were asymptomatic and 30.35% (26/87) of trichomoniasis patients were asymptomatic. The above infections were common in the age group 25-35. Holistic screening protocol was incorporated for all female patients attending STD clinic even if asymptomatic and should be treated accordingly to prevent the acquisition of other serious sexually transmitted infections.

    Anorectal symptoms and complaints caused by hemorrhoids or anal fissures are common during pregnancy. It is known that one-third of pregnant women complain of anal pain in the third trimester. Anal pain may be caused by a wide spectrum of conditions, but if it begins gradually and becomes excruciating within a few days it may indicate anorectal abscess. We experienced a case of anorectal abscess during pregnancy which was diagnosed by magnetic resonance imaging and treated by incision and seton drainage at 36 weeks of gestation, followed by a normal spontaneous delivery at 38 weeks of gestation. To our knowledge, this is the first case report of anorectal abscess during pregnancy in the English-language published work. The clinical course of our case and clinical considerations of anorectal abscesses are discussed.

    Anorectal melanoma is an uncommon and aggressive disease. Because the patients often present with non specific complaints, a high clinical suspicion is important to avoid a delayed diagnosis. Patients undergoing radical surgery have no significant survival difference compared to those undergoing wide local excision. Abdominoperineal resection should be reserved for selected patients in whom local excision is not technically possible or cannot obtain a clear margin. The indiscriminate use of groin dissection is not advisable in anorectal melanoma and should be use in selected cases. Systemic chemotherapy is generally a non effective treatment and continues be studied. Radiation therapy can be used as hypofractionated radiation therapy combined with local excision or in a palliative setting. The oncological outcomes in anorectal melanoma are very poor. The aim of the present study is to review clinicopathology features and management of anorectal melanoma. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

    Anorectal disorders result in many visits to healthcare specialists. These disorders include benign conditions such as hemorrhoids to more serious conditions such as malignancy; thus, it is important for the clinician to be familiar with these disorders as well as know how to conduct an appropriate history and physical examination. This article reviews the most common anorectal disorders, including hemorrhoids, anal fissures, fecal incontinence, proctalgia fugax, excessive perineal descent, and pruritus ani, and provides guidelines on comprehensive evaluation and management.

    We report the prevalence and incidence of 3 treatable sexually transmitted pathogens (Neiserria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis) in women who were HIV infected or at high risk for HIV infection, in pregnancy and postpartum, respectively. Vulvovaginal specimens collected at the first antenatal visit and again at 14 weeks postpartum were tested for N. gonorrhoeae, C. trachomatis, and T. vaginalis in the laboratory. Women were routinely tested for HIV-1 with a point-of-care test. Among 1480 women, 32.3% (95% confidence interval, 29.9-34.7) tested positive for any of the sexually transmitted infections (STIs) in pregnancy and 19.2% (95% confidence interval, 16.9-21.5) were positive when retested 14 weeks postpartum (incidence rate, 79.2 per 100 person-years). The prevalence of N. gonorrhoeae and T. vaginalis infections in pregnancy and the incidence rate of any STI at 14 weeks postpartum were significantly higher in HIV-1-infected women (P < 0.0001 amd P = 0.0079). More than 50% of N. gonorrhoeae, T. vaginalis, and C. trachomatis infections in pregnancy were asymptomatic. The high prevalence of asymptomatic STIs in pregnancy is compelling evidence that demands the development and validation of point-of-care tests for STIs be expedited. In addition, the high incidence of STIs 3 months postpartum suggests that women in this study setting resume unprotected sexual intercourse soon after delivery.

    The prevalence of asymptomatic chlamydial and gonococcal infections in male and female military populations was determined using urine-based ligase chain reaction DNA amplification assays (DAAs). Cross-sectional surveys in four military settings revealed an overall prevalence of asymptomatic chlamydial infection of 4.2% (56/1338). This included 3.4% (21/618) of Western Pacific shipboard US Marine Corps enlisted men; 5.2% (21/406) of male marines shore-based in Okinawa, Japan; 2.7% (5/183) of female enlisted US Navy subtender personnel in dry dock; and 6.9% (9/131) of shore-based female naval personnel in San Diego. No gonococcal infections were detected. All subjects were treated within 2 weeks of screening; none of them had progressed to symptomatic disease. General population-based screening for asymptomatic sexually transmitted diseases, and in particular chlamydial infection, can be successfully implemented using urine-based DAA tests. Benefits are maximized in a population in which compliance for follow-up therapy is high.

    The detection of primary anorectal melanoma on anal cytology is a rare and challenging diagnosis. We report a case where anorectal cytology showed isolated malignant cells with oval nuclei, prominent nucleoli, and elongated wispy cytoplasmic projections. There was no evidence of squamous dysplasia or melanin pigment identified. To the best of our knowledge, this is the first reported case of a primary anorectal melanoma detected in anorectal cytology. Detection of malignancies other than squamous cell carcinoma can be seen on anorectal cytology and should be considered when there is no evidence of anal intraepithelial neoplasia. Diagn.

    To assess the prevalence of asymptomatic urethral gonorrhea and chlamydia men who have sex with men (MSM) living in greater Boston, 206 men attending routine medical appointments consented to urine-based chlamydia and gonorrhea screening using urine LCR amplification. Of those screened, 201 patients also completed a seven-question survey to assess sexual risk behaviors associated with urethral sexually transmitted infections. Less than 1% of the asymptomatic patients screened tested positive for urethral chlamydia; none tested positive for urethral gonorrhea. Forty-eight percent reported multiple sexual partners in the 30 days prior to screening, with HIV-infected patients reporting fewer partners and less unprotected insertive anal sex than HIV-uninfected patients. Almost 25% of patients screened used the Internet in the 30 days prior to screening to find a sexual partner. Internet use was associated with increased numbers of sexual partners in the 30 days prior to screening. Findings suggest that asymptomatic urethral chlamydia and gonorrhea may be uncommon in MSM living in the greater Boston area and that the recent rise in the prevalence of sexually transmitted infections may not be due to untreated asymptomatic infections. Increased awareness of STD symptoms among patients and medical providers is critical to timely diagnosis and treatment of STDs in MSM.

  7. Anorectal conditions: anal fissure and anorectal fistula.

    Anal fissures are linear splits in the anal mucosa. Acute fissures typically resolve within a few weeks; chronic fissures persist longer than 8 to 12 weeks. Most fissures are posterior and midline and are related to constipation or anal trauma. Painful defecation and rectal bleeding are common symptoms. The diagnosis typically is clinical. High-fiber diet, stool softeners, and medicated ointments relieve symptoms and speed healing of acute fissures but offer limited benefit in chronic fissures. Lateral internal sphincterotomy is the surgical management of choice for chronic and refractory acute fissures. Anorectal fistula is an abnormal tract connecting the anorectal mucosa to the exterior skin. Fistulas typically develop after rupture or drainage of a perianal abscess. Fistulas are classified as simple or complex; low or high; and intersphincteric, transsphincteric, suprasphincteric, or extrasphincteric. Inspection of the perianal area identifies the skin opening, and anoscopy visualizes internal openings. The goal of management is to obliterate the tract and openings with negligible sphincter disruption to minimize incontinence. Fistulotomy is effective for simple fistulas; patients with complex fistulas may require fistulectomy. Other procedures that are used include injection of fibrin glue or insertion of a bioprosthetic plug into the fistula opening.

    This report defines criteria for diagnosing functional anorectal disorders (ie, fecal incontinence, anorectal pain, and disorders of defecation). Functional fecal incontinence is defined as the uncontrolled passage of fecal material recurring for > or =3 months in an individual with a developmental age of > or =4 years that is associated with: (1) abnormal functioning of normally innervated and structurally intact muscles, and/or (2) no or minor abnormalities of sphincter structure and/or innervation insufficient to explain fecal incontinence, and/or (3) normal or disordered bowel habits (ie, fecal retention or diarrhea), and/or (4) psychological causes. However, conditions wherein structural and/or neurogenic abnormalities explain the symptom, or are part of a generalized process (eg, diabetic neuropathy) are not included within functional fecal incontinence. Functional fecal incontinence is a common, but underrecognized symptom, which is equally prevalent in men and women, and can often cause considerable distress. The clinical features are useful for guiding diagnostic testing and therapy. Functional anorectal pain syndromes include proctalgia fugax (fleeting pain) and chronic proctalgia; chronic proctalgia may be subdivided into levator ani syndrome and unspecified anorectal pain, which are defined by arbitrary clinical criteria. Functional defecation disorders are characterized by 2 or more symptoms of constipation, with > or =2 of the following features during defecation: impaired evacuation, inappropriate contraction of the pelvic floor muscles, and inadequate propulsive forces. Functional disorders of defecation may be amenable to pelvic floor retraining by biofeedback therapy (such as dyssynergic defecation).

    Anorectal injuries associated with sexual practices have become more frequently reported in the last decade. Although anorectal injuries are commonly reported in cases of sexual abuse of children, fatalities are very rare. In this series of cases, we report a case of fatal child abuse resulting from anal intercourse. In addition, there are two cases of death in females as a result of heterosexual "fisting" or "handballing." The fourth case of the series is that of a homicidal injury produced by rectal impalement with a 31 inch length of threaded pipe.

    The natural history of Epstein-Barr virus (EBV) infection is poorly defined. We report the prevalence and subsequent incidence of EBV infection in a cohort of sexually active young women and explore the social and sexual determinants of incident infections. The study population was drawn from a cohort of young women, who were recruited for a longitudinal study of risk factors for early cervical neoplasia. A case-control analysis, nested within the cohort of 45 women for whom the first EBV sample tested was EBV-negative and who had further follow-up, was undertaken. EBV serostatus was determined in serum with a synthetic peptide-based enzyme-linked immunosorbent assay; EBV DNA was measured in cervical smears with the use of quantitative polymerase chain reaction. Of 1023 women 15-19 years of age included in this analysis, 978 (95.6%) tested positive for antibodies to EBV in their first serum sample. Of 45 women who tested negative, 22 subsequently acquired an asymptomatic EBV infection; the median time to seroconversion was 25 months (range, 1-60 months), and the median age at seroconversion was 18 years (range, 16-21 years). The risk of seroconversion increased with increasing number of sexual partners [compared with 1 partner, odds ratio (OR) was 1.28 for 2 partners and 2.23 for 3 or more; chiTREND 5.02; df 1; P < 0.05] and was greatest when a new sexual partner had been acquired in the 2 years before seroconversion (OR 4.78; chi 4.62; df 1; P < 0.05). EBV DNA was detected in 9 of 14 women who seroconverted and who also provided cervical samples. In susceptible young women, the acquisition of EBV infection is associated with their sexual behavior.

    Improving access to genitourinary (GU) medicine services in the face of increasing demand and escalating rates of sexually transmitted infections (STIs) necessitates a review of current practice and modernization of service provision. At a time when GU medicine resources are limited and technology is available to perform non-invasive screening tests for chlamydia and gonorrhoea, we question the cost-effectiveness of routine genital examination, microscopy and culture of a high vaginal swab (HVS) in the management of asymptomatic women attending a GU medicine clinic. We conducted a case-note review of 206 consecutive asymptomatic female GU medicine clinic attendees who requested 'a check up'. We conclude that routine on-site microscopy of samples from the cervix, urethra and vagina, and laboratory culture of a HVS did not influence the outcome of patient care. No clinically significant genital tract pathology was identified on examination, with the possible exception of one woman in whom HSV1 was diagnosed opportunistically. The results of this study have significant implications for service provision and patient management.

    Although pelvic pain is a symptom of several structural anorectal and pelvic disorders (eg, anal fissure, endometriosis, and pelvic inflammatory disease), this comprehensive review will focus on the 3 most common nonstructural, or functional, disorders associated with pelvic pain: functional anorectal pain (ie, levator ani syndrome, unspecified anorectal pain, and proctalgia fugax), interstitial cystitis/bladder pain syndrome, and chronic prostatitis/chronic pelvic pain syndrome. The first 2 conditions occur in both sexes, while the latter occurs only in men. They are defined by symptoms, supplemented with levator tenderness (levator ani syndrome) and bladder mucosal inflammation (interstitial cystitis). Although distinct, these conditions share several similarities, including associations with dysfunctional voiding or defecation, comorbid conditions (eg, fibromyalgia, depression), impaired quality of life, and increased health care utilization. Several factors, including pelvic floor muscle tension, peripheral inflammation, peripheral and central sensitization, and psychosocial factors, have been implicated in the pathogenesis. The management is tailored to symptoms, is partly supported by clinical trials, and includes multidisciplinary approaches such as lifestyle modifications and pharmacological, behavioral, and physical therapy. Opioids should be avoided, and surgical treatment has a limited role, primarily in refractory interstitial cystitis. Copyright © 2016 Mayo Foundation for Medical Education and Research.

    Many patients present to emergency departments with anorectal problems, such as haemorrhoids, anal fissure and pruritis ani. Often, patients with such problems are embarrassed about them or fearful about their potential diagnoses, so practitioners must approach history taking and examination sensitively. They should also have a good understanding of the anatomy of the anorectal area, and be able to recognise the signs and symptoms of relevant conditions. This article provides an overview of the anatomy and physiology of the anorectal area, explains how to undertake anorectal examinations, and describes the signs and symptoms of some common conditions.

    To ascertain why active and passive oral-anal and genital anal intercourse correlate strongly with hepatitis B virus (HBV) infection in homosexual men, we studied 22 men with HBV infection for the presence of hepatitis B surface antigen (HBsAg) in gingival and anorectal mucosa, feces, and semen. Thirteen of 22 (59%) patients had asymptomatic rectal mucosal lesions consisting of punctate bleeding points. Seventy-seven percent of swabbed specimens from lesions, 62% from feces, 59% from rectal mucosa, and 50% from anal canal mucosa contained HBsAg. Sera diluted serially and tested for HBsAg by radioimmunoassay showed that men with serum titers of 105 or greater were more likely to have HBsAg in specimens from lesions (p = 0.034), feces (p = 0.032), and normal mucosa (p = 0.001) than men with titers under 10 5. Asymptomatic rectal bleeding is frequent in homosexual men with persistent HBV infection. Rectal mucosa, feces, and anal canal mucosa become contaminated with HBsAg, creating a setting for de facto parenteral transmission when there is contact with oral or urethral mucosa.

    To provide data on incidence of early diagnosis of HIV infections and define prevalence and incidence of asymptomatic STI in MSM. Prospective cohort study of HIV-uninfected MSM at high-risk for HIV-infection. Participants were selected through a risk-assessment questionnaire, and screened for HIV-infection (quarterly) and for other STIs (yearly): syphilis, hepatitis A, B and C (serology); C. trachomatis and N. gonorrhoeae in penis and rectum and Human Papillomavirus in anus and mouth (PCR). Between November 2009 and October 2012, 258 HIV-uninfected MSM at high-risk for HIV-infection were included and followed-up during [median (IQR)] 2 (1.4, 2.5) years. Nineteen acute HIV-infections were diagnosed (incidence: 3.9 per 100 person-years). Prevalence of STIs at baseline was: syphilis 8.4% (95%CI: 5.4-12.7); HCV 2.0% (95%CI: 0.7-4.8); C. trachomatis in penis 3.2% (95%CI:1.5-6.5), in rectum 6.5% (95%CI:3.9-10.5); N. gonorrhoeae in penis 2.0% (95%CI:0.8-5.0), in rectum 6.1% (95%CI:3.6-10.1); HPV in anal canal 75.7% (95%CI:68.8-81.5), in mouth 3.8% (95%CI:1.8-7.7). The implementation of the Check-ear-project in a MSM community centre allowed for the identification of early HIV-infections and asymptomatic STI among MSM. The high incidence of HIV infections and the high prevalence of STIs, strongly supports the recommendation of periodical screenings among sexually active MSM. Copyright © 2017.

    The purpose of this study was to determine whether treatment of bacterial vaginosis (BV) decreases the incidence of sexually transmitted diseases (STDs). Women with asymptomatic BV were studied prospectively to determine the effect of treatment of BV for the prevention of STD. Women were assigned randomly to observation or treatment and prophylaxis with intravaginal metronidazole gel. Women were screened monthly for STDs. Women who were assigned randomly to receive metronidazole gel had a significantly longer time to the development of STDs compared with women in the observation group (P = .02). The 6-month STD rate was 1.58 per person-year (95% CI, 1.29, 1.87) for women in the metronidazole gel group vs 2.29 per person-year (95% CI, 1.95, 2.63) for women in the observational group. The difference in STD rates was driven by a significant difference in the number of chlamydial infections (P = .013). Treatment and twice-weekly prophylactic use of intravaginal metronidazole gel resulted in significantly fewer cases of chlamydia.

    Proctitis is defined as an inflammatory syndrome of the distal 10-12 cm of the anal canal, also called the rectum. Infectious proctitis can be sexually transmitted via genital-anal mucosal contact, but some also via mutual masturbation.N. gonorrhoeae,C. trachomatis(including lymphogranuloma venereum), Herpes Simplex Virus andT. pallidumare the most common sexually transmitted anorectal pathogens. Shigellosis can be transferred via oral-anal contact and may lead to proctocolitis or enteritis. Although most studies on these infections have concentrated on men who have sex with men (MSM), a significant proportion of women have anal intercourse and therefore may also be at risk. A presumptive clinical diagnosis of proctitis can be made when there are symptoms and signs, and a definitive diagnosis when the results of laboratory tests are available. The symptoms of proctitis include anorectal itching, pain, cramps (tenesmus) and discharge in and around the anal canal. Asymptomatic proctitis occurs frequently and can only be detected by laboratory tests. The majority of rectal chlamydia and gonococcal infections are asymptomatic. Therefore when there is a history of receptive anal contact, exclusion of anorectal infections is generally indicated as part of standard screening for sexually transmitted infections (STIs). Condom use does not guarantee protection from bacterial and protozoan STIs, which are often spread without penile penetration.

  19. High co-occurrence of anorectal chlamydia with urogenital chlamydia in women visiting an STI clinic revealed by routine universal testing in an observational study; a recommendation towards a better anorectal chlamydia control in women

    2014-01-01

    Background Symptom- and sexual history-based testing i.e., testing on indication, for anorectal sexually transmitted infections (STIs) in women is common. Yet, it is unknown whether this strategy is effective. Moreover, little is known about alternative transmission routes i.e. by fingers/toys. This study assesses anorectal STI prevalence and infections missed by current testing practice, thereby informing the optimal control strategy for anorectal STIs in women. Methods Women (n = 663) attending our STI-clinic between May 2012-July 2013 were offered routine testing for anorectal and urogenital Chlamydia trachomatis and Neisseria gonorrhoeae. Data were collected on demographics, sexual behaviour and symptoms. Women were assigned to one of the categories: indication (reported anal sex/symptoms), fingers/toys (only reported use of fingers/toys), or without indication. Results Of women, 92% (n = 654) participated. There were 203 reports (31.0%) of anal sex and/or symptoms (indication), 48 reports (7.3%) of only using fingers/toys (fingers/toys), and 403 reports (61.6%) of no anal symptoms, no anal sex and no anal use of fingers/toys (without indication). The overall prevalence was 11.2% (73/654) for urogenital chlamydia and 8.4% (55/654) for anorectal chlamydia. Gonorrhoea infections were not observed. Prevalence of anorectal chlamydia was 7.9% (16/203) for women with indication and 8.6% (39/451) for all other women (P = 0.74). Two-thirds (39/55) of anorectal infections were diagnosed in women without indication. Isolated anorectal chlamydia was rare (n = 3): of all women with an anorectal infection, 94.5% (52/55) also had co-occurrence of urogenital chlamydia. Of all women with urogenital chlamydia, 71.2% (52/73) also had anorectal chlamydia. Conclusions Current selective testing on indication of symptoms and sexual history is not an appropriate control strategy for anorectal chlamydia in women visiting an STI clinic.

    Background Anorectal transplantation is a method for patients who have lost their anorectal function or suffer from congenital anorectal dysfunction to recover this function, and this has been investigated in experimental animal models using pigs, dogs, and rats. In this study, we performed an examination of anorectal transplantation in human cadavers to investigate whether this procedure could be performed in patients. Methods A 77-year-old woman cadaver 1 was used as the donor and a 98-year-old woman cadaver 2 was used as the recipient. Initially, abdominoperineal excision of the anus and rectum (the Miles’ operation) was performed on the recipient. Next, an anorectal graft containing the pudendal nerve (PN), pudendal artery (PA), pudendal vein (PV), inferior mesenteric artery (IMA), and inferior mesenteric vein (IMV) was harvested from the donor. The donor graft was transplanted into the recipient by intestinal anastomosis and microneurovascular anastomoses orthotopically. Results The diameters of the PN (right/left), IMA, and IMV were 2.5 mm/2.5 mm, 2.0 mm, and 1.5 mm, respectively, in cadaver 1, and 2.0 mm/2.0 mm, 2.0 mm, and 2.0 mm, respectively, in cadaver 2. The length of the PN, PA, PV, IMA, and IMV in the graft was sufficient to allow proper anastomosis. Conclusion This preliminary study indicated that human anorectal transplantation was possible anatomically and technically. We anticipate our study will aid in the potential future application of this procedure to human patients. PMID:23874833

  2. Anorectal Infection: Abscess–Fistula

    PubMed Central

    Abcarian, Herand

    2011-01-01

    Anorectal abscess and fistula are among the most common diseases encountered in adults. Abscess and fistula should be considered the acute and chronic phase of the same anorectal infection. Abscesses are thought to begin as an infection in the anal glands spreading into adjacent spaces and resulting in fistulas in ~40% of cases. The treatment of an anorectal abscess is early, adequate, dependent drainage. The treatment of a fistula, although surgical in all cases, is more complex due to the possibility of fecal incontinence as a result of sphincterotomy. Primary fistulotomy and cutting setons have the same incidence of fecal incontinence depending on the complexity of the fistula. So even though the aim of a surgical procedure is to cure a fistula, conservative management short of major sphincterotomy is warranted to preserve fecal incontinence. However, trading radical surgery for conservative (nonsphincter cutting) procedures such as a draining seton, fibrin sealant, anal fistula plug, endorectal advancement flap, dermal island flap, anoplasty, and LIFT (ligation of intersphincteric fistula tract) procedure all result in more recurrence/persistence requiring repeated operations in many cases. A surgeon dealing with fistulas on a regular basis must tailor various operations to the needs of the patient depending on the complexity of the fistula encountered. PMID:22379401

    Untreated sexually transmitted infections (STIs) and bacterial vaginosis (BV) cause genital inflammation and increase the risk of HIV infection. WHO-recommended syndromic STI and BV management is severely limited as many women with asymptomatic infections go untreated. The purpose of this cross-sectional study was to evaluate genital cytokine profiles as a biomarker of STIs and BV to identify women with asymptomatic, treatable infections. Concentrations of 42 cytokines in cervicovaginal lavages from 227 HIV-uninfected women were measured using Luminex. All women were screened for BV by microscopy and STIs using molecular assays. Multivariate analyses were used to identify cytokine profiles associated with STIs/BV. A multivariate profile of seven cytokines (interleukin (IL)-1α, IL-1β, tumour necrosis factor-β, IL-4, fractalkine, macrophage-derived chemokine, and interferon-γ) most accurately predicted the presence of a treatable genital condition, with 77% classification accuracy and 75% cross-validation accuracy (sensitivity 72%; specificity 81%, positive predictive value (PPV) 86%, negative predictive value (NPV) 64%). Concomitant increased IL-1β and decreased IP-10 concentrations predicted the presence of a treatable genital condition without a substantial reduction in predictive value (sensitivity 77%, specificity 72%, PPV 82% and NPV 65%), correctly classifying 75% of the women. This approach performed substantially better than clinical signs (sensitivity 19%, specificity 92%, PPV 79% and NPV 40%). Supplementing syndromic management with an assessment of IL-1β and IP-10 as biomarkers of genital inflammation may improve STI/BV management for women, enabling more effective treatment of asymptomatic infections and potentially reducing their risk of HIV infection.

  4. Asymptomatic bacteriuria.

    Asymptomatic bacteriuria is a common finding. Inappropriate antimicrobial treatment of asymptomatic bacteriuria has been identified as a major issue for antimicrobial stewardship programs. This review summarizes and evaluates recent studies which extend our knowledge of the occurrence, management, and outcomes of bacteriuria. The reported prevalence of bacteriuria is higher in some developing countries than generally reported for developed countries, but reasons for this remain unclear. Clinical studies of young women, renal transplant patients, and patients undergoing minor nontraumatic urologic procedures confirm that treatment of asymptomatic bacteriuria for these populations is not beneficial, and may be harmful. There is also no benefit for treatment of asymptomatic bacteriuria prior to orthopedic surgery to decrease postoperative surgical site infection. Studies continue to report substantial inappropriate antimicrobial use for treatment of asymptomatic bacteriuria. Recent publications confirm that asymptomatic bacteriuria is benign in most patients. Management strategies for pregnant women with recurrent bacteriuria require further clarification. There is a continuing problem with inappropriate treatment of asymptomatic bacteriuria, and sustainable strategies to optimize antimicrobial use for this problem are needed.

    Anorectal malignant melanoma (AMM) is most common primary melanoma of gastrointestinal tract, accounting for 0.05% and 1% of all colorectal and anal cancers. We reported an 85 year-old woman with no significant past medical history who presented two-month period of rectal bleeding, abdominal pain, tenesmus and 2kg weight-loss. Laboratory markers were unremarkable, although rectal examination revealed two small haemorrhoids and a firm, non-obstructing mass in the lower rectum. Colonoscopy confirmed presence of an ulcerated pigmented neoplasm arising at dental line [A,B]. No distant metastases were found on computed tomography [C] although presented metastatic regional lymph nodes on pelvic MRI [D]. Therefore, abdominoperineal resection was performed, confirming loco-regional disease. Histopathology showed malignant melanoma with positive stains in immunohistochemistry for protein S100, HMB-45 and Melan-A [E,F,G,H] and stained negative for c-Kit.

    Anorectal dysfunction resulting in fecal incontinence or permanent colostomy is a current public health concern that strongly impairs patient quality of life. Present treatment options for this complex disease are expensive and usually ineffective. Anorectal transplantation is the logical treatment for fecal incontinence and permanent colostomy. This procedure has been clinically effective in a few cases reported in the medical literature. Furthermore, experiments in rats, pigs, and dogs have shown promising results, with functional recovery of the graft. In this article we describe the scientific evidence that anorectal transplantation may be an important option for treating anorectal dysfunction.

    Thirty-three years ago, on 10 August 1980, in Mexico City, the first patient with an anorectal malformation was operated on using the posterior sagittal approach. At that time it was not obvious that we were actually opening a "Pandora's box" that continues to give many positive surprises, a few disappointments, and the constant hope that each day we can learn more about how to improve the quality of life of children born with all different types of anorectal malformations. In November 2012, patient number 3000 in our database was operated in the city of Cochabamba, Bolivia; during one of our International Courses of Anorectal Malformations and Colorectal Problems in Children. The goal of this article is to give a brief update on the current management of patients with anorectal malformation, based on the multiple lessons learned during this period.

    Modern psychobiologic research conceptualizes personality as a complex adaptive system involving a bidirectional interaction between heritable neurobiologic dispositions (temperament) and social learning (character). In this study, we evaluated temperament and character traits of patients with anorexia nervosa and their mothers and fathers, and we analyzed the correlation of temperament and character traits among family members in anorectic families. Finally, we tested the ability of the Temperament and Character Inventory (TCI) to discriminate between normal controls and anorectic subjects, their parents, and their families. Temperament and character features of 50 restricter anorectic patients and their parents (23 fathers and 25 mothers) were analyzed and then compared with a control group of 60 women and their 20 fathers and 20 mothers using the TCI. Data suggest that both temperament and character factors are involved in anorexia nervosa (AN). Anorectic individuals were high in harm avoidance (HA), low in novelty seeking (NS), and high in persistence (P) ("obsessive temperament type"). Their character was remarkable for low self-directedness (SD). Their mothers were distinguished by low SD. The fathers were high in HA, but also low in P, and high in reward dependence (RD). Again, they were low in SD. The anorectic family had low SD as a common denominator observed in all family members. This finding indicates that the psychopathology of AN extends beyond obsessiveness, but combines obsessiveness with low character development. None of the above temperament and character profiles is pathognomic of restricter anorectics. The observation that both temperament and character have an important role in the etiopathogenesis of AN has important treatment ramifications. The TCI was useful in discriminating between normal controls and anorectic subjects, their parents, and the whole anorectic family.

    In females, fecal incontinence often is attributed to birth trauma; however, symptoms sometimes begin decades after delivery, suggesting that anorectal sensorimotor functions decline with aging. In 61 asymptomatic females (age, 44 +/- 2 years, mean +/- standard error of the mean) without risk factors for anorectal trauma, anal pressures, rectal compliance, and sensation were assessed by manometry, staircase balloon distention, and a visual analog scale during phasic distentions respectively. Anal sphincter appearance and pelvic floor motion also were assessed by static and dynamic magnetic resonance imaging respectively in 38 of 61 females. Aging was associated with lower anal resting (r = -0.44, P < 0.001) and squeeze pressures (r = -0.32, P = 0.01), reduced rectal compliance (i.e., r for pressure at half-maximum volume vs. age = 0.4, P = 0.001), and lower (P anorectal junction at rest (r = 0.52, P < 0.001), squeeze (r = 0.62, P < 0.001), and Valsalva maneuver (r = 0.35, P = 0.03), but not anorectal motion (e.g., from resting to squeeze) was associated with age. In asymptomatic females, aging is associated with reduced anal resting and squeeze pressures, reduced rectal compliance, reduced rectal sensation, and perineal laxity. Together, these changes may predispose to fecal incontinence in elderly females.

    At the University College Hospital, Ibadan, Nigeria, over a 30-month period (January 1975 to June 1977) more than 29 cases were fully studied. Nine patients presented with acute large bowel obstruction. In five cases, colonic neoplasms were palpated abdominally before surgery, and four of the patients were initially being treated for "hemorrhoids". All the patients presented at late stages. There was neither socio-economic nor sexual bias in this affliction. Sixty-nine percent of all the tumors occurred in the anorectal area well within the reach of the index finger, and 27.5% occurred in the right colon. Differential diagnosis included ameboma, rectal schistosomiasis, rectal tubercolosis, anal fistula and adult chronic intermittent intussusception. The treatment administered depended on the nature, location and stage of the disease. There was a case of metastatic squamous cell carcinoma of the hepatic flexure causing obstruction. The metastasis was from carcinoma of the cervix which had been treated with cesium insertions about three years previously. It is now known that colon and anorectal neoplasms, once regarded as rare among Africans living in tropical Africa, is not that rare. With the Africans boycotting native "doctors" in favor of medical institutions, many of the diseases once thought to be rare in Africans will unfortunately become less rare.

    We have described the clinicopathologic findings in two cases of anorectal melanoma, and extracted the salient features from the medical literature. The disease is rare. Melanoma arises from the anal squamous membrane and very often spreads upward through submucosal planes, producing secondary satelites in the rectum. Trauma from defecation, vast lymphatic and venous systems in the anorectal region, and high invasiveness of the tumor cells eviden;ly account for early distant metastases. Histologically, the neoplastic cells often mimic other cancers. Treatment is surgical, with dismal end results.

    Neurofibromatosis type-1 (NF1), also known as Von Recklinghausen disease, is an autosomal dominant disorder with incidence of one per 4000. Neurofibromas are benign, heterogeneous, peripheral nerve sheath tumors coming up from the connective tissue of peripheral nerve sheaths, particularly the endoneurium. Visceral involvement in disseminated neurofibromatosis is considered rare. Neurofibroma occurs most frequently in the stomach and jejunum, but colon and anorectal canal may also be involved. Gastrointestinal neurofibromas may lead to bleeding, obstruction, intussusception, protein-losing enteropathy and bowel perforation. We encountered a case of diffusely involving the anorectal area by huge neurofibroma, which resulted in pelvic pain with watery diarrhea and urgency.

    Plasma ammonia concentrations were significantly elevated by 150% in anorectic rats bearing methylcholanthrene sarcomas. Assessment of ammonia levels in blood draining these sarcomas indicated nearly a 20-fold increase as compared with venous blood in control rats, suggesting the tumor mass as the source of this increase in ammonia. Infusing increasing concentrations of ammonium salts produced anorexia and alterations in brain amino acids in normal rats that were similar to those observed in anorectic tumor-bearing rats. Therefore, these results suggest that ammonia released by tumor tissue may be an important factor in the etiology of cancer anorexia.

    A 4-year-old girl was referred for evaluation for a mild but persistent serum aspartate aminotransferase (AST) elevation detected incidentally during routine blood screening for a skin infection. Serum creatine kinase activity was found to be increased. Immuno-histochemical study for dystrophin in her muscle biopsy showed results consistent with a carrier state for muscular dystrophy. Molecular work-up showed the proposita to be a carrier of a deletion mutation of exon 48 of the dystrophin gene. Four male relatives also had the deletion mutation, yet showed no clinical symptoms of muscular dystrophy (age range 8-58 yrs). Linkage analysis of the dystrophin gene in the family showed a spontaneous change of an STR45 allele, which could be due to either an intragenic double recombination event, or CA repeat length mutation leading to identical size alleles. To our knowledge, this is the first documentation of an asymptomatic dystrophinopathy in multiple males of advanced age. Based on molecular findings, this family would be given a diagnosis of Becker muscular dystrophy. This diagnosis implies the development of clinical symptoms, even though this family is clearly asymptomatic. This report underscores the caution which must be exercised when giving presymptomatic diagnoses based on molecular studies. 28 refs., 4 figs., 1 tab.

    Patients may present with gynecologic concerns after previous posterior sagittal anorectoplasty (PSARP) for repair of an anorectal malformation (ARM). Common findings include an inadequate or shortened perineal body, as well as introital stenosis, retained vaginal septum, and remnant rectovestibular fistula. An inadequate or shortened perineal body may impact fecal continence, sexual function and recommendations regarding obstetrical mode of delivery. We describe our experience with female patients referred to our center for evaluation of their previously repaired ARM, with a specific focus on perineal body anatomy and concomitant gynecologic abnormalities. We outline our collaborative evaluation process and findings as well as subsequent repair and outcomes. A single site retrospective chart review from May 2014 to May 2016 was performed. Female patients with a history of prior ARM repair who required subsequent reoperative surgical repair with perineoplasty were included. The decision for reoperation was made collaboratively after a multidisciplinary evaluation by colorectal surgery, urology, and gynecology which included examination under anesthesia (EUA) with cystoscopy, vaginoscopy, rectal examination, and electrical stimulation of anal sphincters. The type of original malformation, indication for reoperative perineoplasty, findings leading to additional procedures performed at time of perineoplasty, postoperative complications, and the length of follow up were recorded. During the study period 28 patients were referred for evaluation after primary ARM repair elsewhere and 15 patients (60%) met inclusion criteria. Thirteen patients (86.6%) originally had a rectovestibular fistula with prior PSARP and 2 patients (13.4%) originally had a cloacal malformation with prior posterior sagittal anorectovaginourethroplasty. The mean age at the time of the subsequent perineoplasty was 4.6years (0.5-12). Patients had an inadequate perineal body requiring reoperative

    Background and Aims High-resolution manometry (HRM) is used to measure anal pressures in clinical practice but normal values have not been available. While rectal evacuation is assessed by the rectoanal gradient during simulated evacuation, there is substantial overlap between healthy people and defecatory disorders, and the effects of age are unknown. We evaluated the effects of age on anorectal pressures and rectal balloon expulsion in healthy women. Design Anorectal pressures (HRM), rectal sensation, and balloon expulsion time (BET) were evaluated in 62 asymptomatic women ranging in age from 21 to 80 years (median age 44 years) without risk factors for anorectal trauma. Thirty women were aged less than 50 years. Results Age is associated with lower (r = − 0.47, p < 0.01) anal resting [63[5] (≥50 y), 88[3] (<50 y)] but not squeeze pressures; higher rectal pressure and rectoanal gradient during simulated evacuation (r = 0.3, p < 0.05); and a shorter (r = −0.4, p < 0.01) rectal BET [17[9]s (≥50 y) vs 31[10]s (<50 y)]. Only 5 women had a prolonged (> 60 s) rectal BET but 52 had higher anal than rectal pressures (ie, negative gradient) during simulated evacuation. The gradient was more negative in younger (−41[6] mm Hg) than older (−12[6] mm Hg) women and negatively (r = −0.51, p <0.0001) correlated with rectal BET but only explained 16% of the variation in rectal BET. Conclusions These observations provide normal values for anorectal pressures by HRM. Increasing age is associated with lower anal resting pressure, a more positive rectoanal gradient during simulated evacuation, and a shorter BET in asymptomatic women. While the rectoanal gradient is negatively correlated with rectal BET, this gradient is negative even in a majority of asymptomatic women, undermining the utility of a negative gradient for diagnosing defecatory disorders by HRM.

    Neutropenic patients are susceptible to any anorectal disease, and symptomatic anorectal disease afflicts 2-32% of oncology patients. Perianal infections are the most feared complication, considering the lack of natural defense against infectious microorganisms. When septic complications develop, the anorectal disease is potentially fatal, especially in neutropenic patients in whom mortality rates range between 11-57%. Although anorectal diseases are a frequent complication with potentially fatal outcomes among patients with hematologic diseases, sufficient data are not available in the literature. In this study, we aimed to investigate the anorectal complications developing during the neutropenic period in patients with hematologic diseases. A total of 79 patients whose neutropenic period (absolute neutrophil count <500/mcL) continued for 7 days, or longer were included in the study. A total of 34 patients out of 79 (43%) were detected to develop anorectal complications, of them 6 (7.6%) developed an anorectal infection. The patients were characterized according to the hematological disease and its status (active or not), the type of treatment and the presence of a history of an anorectal pathology before the onset of the hematologic disease. Nineteen (24.1%) patients had the history of anorectal disturbances before diagnosis of the hematologic disease, and recurrence of an anorectal pathology was found in 14 out of 19 patients(73.7%). In addition, the overall mortality rate was higher among the patients who developed anorectal complications compared to another group (41.2% vs. 22.2%, p=0.059). Anorectal pathology is a common complication with high recurrence rate in neutropenic patients. Perianal infections are important as they can cause life-threatening outcomes although they are relatively rare among all anorectal complications. Therefore perianal signs and symptoms should be meticulously evaluated concerning early diagnosis and treatment.

    Anorectal complaints are very common and are caused by a variety of mostly benign anorectal disorders. Many anorectal conditions may be successfully treated by primary care physicians in the outpatient setting, but patients tend not to seek medical attention due to embarrassment or fear of cancer. As a result, patients frequently present with advanced disease after experiencing significant decreases in quality of life. A number of patients with anorectal complaints are referred to gastroenterologists. However, gastroenterologists’ knowledge and experience in approaching these conditions may not be sufficient. This article can serve as a guide to gastroenterologists to recognize, evaluate, and manage medically or non-surgically common benign anorectal disorders, and to identify when surgical referrals are most prudent. A review of the current literature is performed to evaluate comprehensive clinical pearls and management guidelines for each topic. Topics reviewed include hemorrhoids, anal fissures, anorectal fistulas and abscesses, and pruritus ani. PMID:19598294

    To investigate the association between anorectal precancerous lesions, including condyloma, and sexually transmitted infections (STI) in Asian population. This prospective study enrolled 2677 patients who underwent high-resolution colonoscopy for anorectal cancer screening. Anorectal lesions were diagnosed based on endoscopic findings and confirmed by biopsy. The association of HIV-1 infection, syphilis, and HBV infection with anorectal lesion was estimated by multivariate logistic regression. In HIV-1-infected patients (n=244), anal canal HPV-DNA was screened and genotyped. Although no malignancy was identified, anorectal condyloma was diagnosed in 32 (1.2%) male patients. 41% of anorectal condyloma cases had no specific lower GI symptoms. Multivariate analysis identified HIV-1 infection, but not syphilis or HBV infection, as an independent significant factor for condyloma (OR: 176.5, 95%CI 22.52-1383, p<0.001). In HIV-1 infected patients, positive type 16/18 HPV-DNA (OR: 4.766, 95%CI 1.838-12.36, p=0.001), lower CD4 cell count (per 100/μl decrement, OR: 1.056, 95%CI 1.056-1.587, p=0.013), and current smoking (OR: 3.828, 95%CI 1.486-9.857, p=0.005) were independently associated with anorectal condyloma. HIV-1 infection, but not syphilis or HBV infection, was identified as a strong risk for anorectal condyloma. Anal HPV 16/18 was highly prevalent in patients with HIV-1 infection, especially in those with condyloma. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Ambulatory surgery is appropriate for most anorectal pathology. Ambulatory anorectal surgery can be performed at reduced cost compared with inpatient procedures with excellent safety, improved efficiency, and high levels of patient satisfaction. Several perioperative strategies are employed to control pain and avoid urinary retention, including the use of a multimodal pain regimen and restriction of intravenous fluids. Ambulatory anorectal surgery often utilizes standardized order sets and discharge instructions. PMID:26929746

    Of 119 patients with surgical correction of anorectal malformations, 47 who were 10-30 years of age were interviewed personally and had manometric studies to evaluate postoperative continence. This clinical study included not only long-term anorectal function but also sexual function. Patients with low type anomalies or with intermediate type anomalies were more likely to be continent, whereas patients with high type lesions had some problems with continence. However, only two of the 16 patients (12%) with high type anomalies were classified as having poor results. This rate is perhaps lower than might be expected. Thus, incontinent patients may become continent even if they were classified as having fecal incontinence before 6 years of age. Most patients who were 15-30 years of age had normal sexual function except for two females with irregular menstruation. These results indicate that achievement of fecal continence and sexual function in patients with high type anomalies treated by abdominoperineal rectoplasty depends on careful dissection as close as possible to the rectal wall and bringing the terminal bowel down exactly within the sling of the puborectal muscle.

    Defecatory disorders are a common cause of chronic constipation and should be managed by biofeedback-guided pelvic floor retraining. While anorectal tests are necessary to diagnose defecatory disorders, recent studies highlight the utility of a careful digital rectal examination. While obstetric anal injury can cause fecal incontinence (FI), diarrhea is a more important risk factor for FI among women in the community, who typically develop FI after age 40. Initial management of fecal incontinence should focus on bowel disturbances. Pelvic floor retraining with biofeedback therapy is beneficial for patients who do not respond to bowel management. Sacral nerve stimulation should be considered in patients who do not respond to conservative therapy.

    Aim: To assess the modifications in the technique of laparoscopic assisted anorectal pull through (LAARP) practiced at our institute and analyze the post operative outcome and associated complications. Materials and Methods: A retrospective study from January 2001 to May 2009 analyzing LAARP for high anorectal malformations. Results: A total of 40 patients - 34 males and six females, in the age group of two months to six years were studied. Staged procedure was done in 39 patients; one child with recto vestibular fistula underwent single stage procedure. All the patients withstood surgery well. One patient required conversion due to problems in gaining enough length for the distal rectum in a patient with rectovesical fistula so colostomy was closed and re-located at a proximal splenic flexure. The complications were mucosal prolapse (six cases), anal stenosis (three), adhesive obstruction (two), distal rectal necrosis (one), and urethral diverticulum (one). The patients were followed up with clinical evaluation and continence scoring. The progress has been satisfactory and weight-gain is adequate. Conclusions: The advantages of the reformed techniques are as follows: Transcutaneous bladder stitch provides excellent visualization; traction over the fistula helps in dissection of the puborectalis, dividing the fistula without ligation is safe, railroading of Hegar's dilators over the suction canula creates adequate pull through channel, saves time and makes procedure simpler with reproducible comparable reports.

    Introduction. The objective of this case report is to illustrate a severe perineal impalement injury, associated with anorectal avulsion and hemorrhagic shock. Results. A 32-year-old male patient was referred to our hospital for an impalement perineal trauma, associated with complex pelvic fracture and massive perineal soft tissue destruction and anorectal avulsion. On arrival, the systolic blood pressure was 85 mm Hg and the hemoglobin was 7.1 g/dL. The patient was transported to the operating room, and perineal lavage, hemostasis, and repacking were performed. After 12 hours in the Intensive Care Unit, the abdominal ultrasonography revealed free peritoneal fluid. We decided emergency laparotomy, and massive hemoperitoneum due to intraperitoneal rupture of pelvic hematoma was confirmed. Pelvic packing controlled the ongoing diffuse bleeding. After 48 hours, the relaparotomy with packs removal and loop sigmoid colostomy was performed. The postoperative course was progressive favorable, with discharge after 70 days and colostomy closure after four months, with no long-term complications. Conclusions. Severe perineal injuries are associated with significant morbidity and mortality. Their management in high volume centers, with experience in colorectal and trauma surgery, allocating significant human and material resources, decreases the early mortality and long-term complications, offering the best quality of life for patients.

    The anatomical types of female anorectal malformation (ARM) are complex and include several rare and regional variants. The aim of this report is to highlight the diagnosis and management of cases of anorectal agenesis with rectovaginal fistula (RVF). This is a retrospective chart review of cases of RVF who underwent definitive surgery between November 2000 and September 2016 in a single institution. Of the 244 female patients with anorectal anomalies treated in our institution over a 16-year period, there were 15 cases of RVF with anorectal agenesis giving it an incidence of 6%. All cases of RVF with anorectal agenesis presented with absence of anal opening, varying degree of abdominal distension, and history of passage of fecal matter per vaginum. The mean age of presentation was 3 months (newborn to 1 year). Sigmoid colostomy was done in 13 cases. Distal colostogram demonstrated high RVF which was further confirmed by examination under anesthesia (EUA) and endoscopy before definitive surgery. With the posterior sagittal approach, division of the RVF and anorectoplasty was possible in 14 cases; however, one patient required an abdominal mobilization of the colon for pull through due to a very short distal bowel segment. During a mean postoperative follow-up of 5 years, cosmetic and functional results were satisfactory. RVF with anorectal agenesis is a rare/regional variant of female ARMs. Clinical examination along with distal colostogram, EUA, and endoscopy clinches the diagnosis. Anorectal reconstruction by posterior sagittal anorectoplasty results in a satisfactory outcome.

  14. Asymptomatic bacteriuria in pregnancy.

    PubMed

    Smaill, Fiona

    2007-06-01

    Screening for asymptomatic bacteriuria is a standard of obstetrical care and is included in most antenatal guidelines. There is good evidence that treatment of asymptomatic bacteriuria will decrease the incidence of pyelonephritis. All pregnant women should be screened for asymptomatic bacteriuria, and there are no new data that would indicate otherwise. Antibiotic treatment of asymptomatic bacteriuria is associated with a decrease in the incidence of preterm delivery or low birth weight, but the methodological quality of the studies means any conclusion about the strength of this association needs to be drawn cautiously. A better understanding of the mechanism by which treatment of asymptomatic bacteriuria could prevent preterm delivery is needed. While several rapid screening tests have been evaluated, none perform adequately to replace urine culture for detecting asymptomatic bacteriuria. Until there are data from well-designed trials that establish the optimal duration of therapy for asymptomatic bacteriuria, standard treatment courses are recommended.

    Anorectal malformation (ARM) is a severe congenital anomaly that can occur either isolated or in association with other congenital abnormalities. It has a heterogeneous etiology with contribution of both genetic and environmental factors, although the etiological factors remain largely unknown. Several chromosomal abnormalities have been described in patients with an ARM. These chromosomal abnormalities could point to specific genes involved in the development of the anorectal canal and associated structures. This paper reviews the chromosomal abnormalities described in ARM and may act as a starting point to identify chromosomal regions containing putative anorectal development genes.

    Contrary to conventional wisdom, the rectoanal gradient during evacuation is negative in many healthy people, undermining the utility of anorectal high-resolution manometry (HRM) for diagnosing defecatory disorders. We aimed to compare HRM and magnetic resonance imaging (MRI) for assessing rectal evacuation and structural abnormalities. We performed a retrospective analysis of 118 patients (all female; 51 with constipation, 48 with fecal incontinence, and 19 with rectal prolapse; age, 53 ± 1 years) assessed by HRM, the rectal balloon expulsion test (BET), and MRI at Mayo Clinic, Rochester, Minnesota, from February 2011 through March 2013. Thirty healthy asymptomatic women (age, 37 ± 2 years) served as controls. We used principal components analysis of HRM variables to identify rectoanal pressure patterns associated with rectal prolapse and phenotypes of patients with prolapse. Compared with patients with normal findings from the rectal BET, patients with an abnormal BET had lower median rectal pressure (36 vs 22 mm Hg, P = .002), a more negative median rectoanal gradient (-6 vs -29 mm Hg, P = .006) during evacuation, and a lower proportion of evacuation on the basis of MRI analysis (median of 40% vs 80%, P < .0001). A score derived from rectal pressure and anorectal descent during evacuation and a patulous anal canal was associated (P = .005) with large rectoceles (3 cm or larger). A principal component (PC) logistic model discriminated between patients with and without prolapse with 96% accuracy. Among patients with prolapse, there were 2 phenotypes, which were characterized by high (PC1) or low (PC2) anal pressures at rest and squeeze along with higher rectal and anal pressures (PC1) or a higher rectoanal gradient during evacuation (PC2). In a retrospective analysis of patients assessed by HRM, measurements of rectal evacuation by anorectal HRM, BET, and MRI were correlated. HRM alone and together with anorectal descent during evacuation may identify

    Gastroenterologists frequently encounter pelvic floor disorders, which affect 10–15% of the population. The anorectum is a complex organ that collaborates with the pelvic floor muscles to preserve fecal continence and enable defecation. A careful clinical assessment is critical for the diagnosis and management of defecatory disorders and fecal incontinence. Newer diagnostic tools (e.g., high resolution manometry and magnetic resonance defecography) provide a refined understanding of anorectal dysfunctions and identify phenotypes in defecatory disorders and fecal incontinence. Conservative approaches including biofeedback therapy are the mainstay for managing these disorders; new minimally-invasive approaches may benefit a subset of patients with fecal incontinence but more controlled studies are needed. This mini-review highlights these advances, current concepts and controversies in the area. PMID:24211860

    Thirteen cases of anorectal Herpesivirus hominis infection in male homosexuals are described. Symptoms included pruitus ani in 11 cases, while 7 noticed intense and pain. Change of bowel habits and anal discharge were not presenting symptoms in the majority. None had generalized complications. Inguinal lymphadenopathy, a vesicular eruption, and superficial ulceration around the anal margin were commonly found. Some developed vesicular spread to the natal cleft. Treatment with cotrimoxazole to prevent masking of possible coexistent syphilis, though satisfactory in preventing secondary infection seemed to have little effect on early resolution of the lesions. Relapse occurred in over one third of the patients. Infection with Herpesvirus hominis seems an uncommon but increasingly recognized hazard for the passive homosexual and should be included in the differential diagnosis of lesions presenting at the anus.

    Transumbilical surgical procedures have been reported to be a feasible, safe, and cosmetically excellent procedure for various pediatric surgical diseases. Umbilical loop colostomies have previously been created in patients with Hirschsprung's disease, but not in patients with anorectal malformations (ARMs). We assessed the feasibility and cosmetic results of temporal umbilical loop colostomy (TULC) in patients with ARMs. A circumferential skin incision was made at the base of the umbilical cord under general anesthesia. The skin, subcutaneous tissue, and fascia were cored out vertically, and the umbilical vessels and urachal remnant were individually ligated apart from the opening in the fascia. A loop colostomy was created in double-barreled fashion with a high chimney more than 2 cm above the level of the skin. The final size of the opening in the skin and fascia was modified according to the size of the bowel. The bowel wall was fixed separately to the peritoneum and fascia with interrupted 5-0 absorbable sutures. The bowel was opened longitudinally and everted without suturing to the skin. The loop was divided 7 days postoperatively, and diversion of the oral bowel was completed. The colostomy was closed 2-3 months after posterior saggital anorectoplasty through a peristomal skin incision followed by end-to-end anastomosis. Final wound closure was performed in a semi-opened fashion to create a deep umbilicus. TULCs were successfully created in seven infants with rectourethral bulbar fistula or rectovestibular fistula. Postoperative complications included mucosal prolapse in one case. No wound infection or spontaneous umbilical ring narrowing was observed. Skin problems were minimal, and stoma care could easily be performed by attaching stoma bag. Healing of umbilical wounds after TULC closure was excellent. The umbilicus may be an alternative stoma site for temporary loop colostomy in infants with intermediate-type anorectal malformations, who undergo radical

    Patients with functional gastrointestinal disorders often demonstrate abnormal visceral sensation. Currently, rectal sensation is assessed by manual balloon distension or barostat. However, neither test is adaptable for use in the neurophysiological characterization of visceral afferent pathways by sensory evoked potentials. The aim of this study was to assess the reproducibility and quality of sensation evoked by electrical stimulation (ES) and rapid balloon distension (RBD) in the anorectum and to apply the optimum stimulus to examine the visceral afferent pathway with rectal evoked potentials. Healthy subjects (n = 8, median age 33 yr) were studied on three separate occasions. Variability, tolerance, and stimulus characteristics were assessed with each technique. Overall ES consistently invoked pain and was chosen for measuring rectal evoked potential whereas RBD in all cases induced the strong urge to defecate. Rectal intraclass correlation coefficient (ICC) for ES and RBD (0.82 and 0.72, respectively) demonstrated good reproducibility at pain/maximum tolerated volume but not at sensory threshold. Only sphincter ICC for ES at pain showed acceptable between-study reproducibility (ICC 0.79). Within studies ICC was good (>0.6) for anorectal ES and RBD at both levels of sensation. All subjects reported significantly more unpleasantness during RBD than ES (P < 0.01). This study demonstrates that ES and RBD are similarly reproducible. However, the sensations experienced with each technique differed markedly, probably reflecting differences in peripheral and/or central processing of the sensory input. This is of relevance in interpreting findings of neuroimaging studies of anorectal sensation and may provide insight into the physiological characteristics of visceral afferent pathways in health and disease.

    Psychodynamic clinical studies as well as empirical research have pointed out the importance and the specificity of object relations in eating disorders. Given this, the aim of this work was to identify the presence of significant differences in the object relations patterns, as described by the Parental Bonding Instrument (PBI), between anorectic and bulimic subjects. PBI was administered to 42 anorectic female and 26 bulimic female subjects, consecutively admitted to the Eating Disorders Outpatient Unit of H San Raffaele of Milan. Profile analysis revealed the presence of significant (T2 = 11.3453, d.f. 3,64, p = 0.017) qualitative differences in PBI profiles between anorectic and bulimic subjects. The most striking difference was represented by the bulimics' view of their parents as both caring and overwhelming, which contrasted with the anorectics' perception of their parents as absolutely caring.

    Obestatin is a recently discovered peptide produced in the stomach, which was originally described to suppress food intake and decrease body weight in experimental animals. We investigated fasting plasma obestatin levels in normal weight, obese and anorectic women and associations of plasma obestatin levels with anthropometric and hormonal parameters. Hormonal (obestatin, ghrelin, leptin, insulin) and anthropometric parameters and body composition were examined in 15 normal weight, 21 obese and 15 anorectic women. Fasting obestatin levels were significantly lower in obese than in normal weight and anorectic women, whereas ghrelin to obestatin ratio was increased in anorectic women. Compared to leptin, only minor differences in plasma obestatin levels were observed in women who greatly differed in the amount of fat stores. However, a negative correlation of fasting obestatin level with body fat indexes might suggest a certain role of obestatin in the regulation of energy homeostasis. A significant relationship between plasma obestatin and ghrelin levels, independent of anthropometric parameters, supports simultaneous secretion of both hormones from the common precursor. Lower plasma obestatin levels in obese women compared to normal weight and anorectic women as well as increased ghrelin to obestatin ratio in anorectic women might play a role in body weight regulation in these pathologies.

    The association of colon aganglionosis and anorectal malformation is very rare. The objective is to show five clinical cases of anorectal malformation associated with Hirschprung's disease and its treatment and evolution. A retrospective, transverse, descriptive study was carried out at the National Medical Center "20 de Noviembre ISSSTE" from 1984 to 1999 that included all files of patients with anorectal malformation associated with Hirschprung's disease corroborated by histopathological studies. From 151 patients with anorectal malformation studied during a period of 15 years, there were five cases (3.2%) of patients found with anorectal malformation associated with Hirschprung's disease. Of these, two were female. Three patients presented with lower anorectal malformation and two with high anorectal malformation. The association of colon aganglionosis and anorectal malformation should be suspected when the patient evolution during the postoperative period presents abdominal distension, constipation, urinary infection and in younger children with necrotizing enterocolitis.

    Anorectal melanoma is a rare disease that carries a poor prognosis. To date, limited genetic analyses confirmed KIT mutations as a recurrent genetic event similar to other mucosal melanomas, occurring in up to 30% of anorectal melanomas. Importantly, a subset of tumors harboring activating KIT mutations have been found to respond to c-Kit inhibitor-based therapy, with improved patient survival at advanced tumor stages. We performed comprehensive targeted exon sequencing analysis of 467 cancer-related genes in a larger series of 15 anorectal melanomas, focusing on potentially actionable variants based on gain- and loss-of-function mutations. We report the identification of oncogenic driver events in the majority (93%) of anorectal melanomas. These included variants in canonical MAPK pathway effectors rarely observed in cutaneous melanomas (including an HRAS mutation, as well as a BRAF mutation resulting in duplication of threonine 599), and recurrent mutations in the tumor suppressor NF1 in 20% of cases, which represented the second-most frequently mutated gene after KIT in our series. Furthermore, we identify SF3B1 mutations as a recurrent genetic event in mucosal melanomas. Our findings provide an insight into the genetic diversity of anorectal melanomas, and suggest significant potential for alternative targeted therapeutics in addition to c-Kit inhibitors for this melanoma subtype.

    The present study was aimed to test the association between asymptomatic bacteriuria during pregnancy, among patients in whom antibiotic treatment was recommended, and perinatal outcome. Our study was also designed to characterize common bacteria and risk factors associated with asymptomatic bacteriuria during pregnancy. A retrospective population-based study comparing all singleton pregnancies of women with and asymptomatic bacteriuria was conducted. Patients with urinary tract infection were excluded from the analysis. Multiple logistic regression model was used to control for confounders. Out of 199,093 deliveries, 2.5% (n = 4890) were in patients with asymptomatic bacteriuria. E. coli was the most common pathogen associated with asymptomatic bacteriuria, representing 78.6% of the cultures with specified growth. Patients with asymptomatic bacteriuria were more likely to deliver preterm (PTD, 13.3%vs. 7.6%, odd ratio (OR) = 1.9, 95% confidence interval CI 1.7-2.0; P < 0.001) and deliver low birth-weight neonates (<2500 g, 13.3%vs. 7.9%, OR = 1.8; 95% CI 1.6-2.0; P < 0.001). Asymptomatic bacteriuria was independently associated with PTD (adjusted OR = 1.6; 95% CI 1.5-1.7; P < 0.001), fertility treatments, hypertensive disorders, recurrent abortions, diabetes mellitus, intrauterine growth restriction, polyhydramnion and oligohydramnion, premature rupture of membranes and labour induction, in a multivariable analysis with backwards elimination. Perinatal mortality rates (1.5%vs. 1.4%; P = 0.707) as well as low 5 min Apgar scores (0.8%vs. 0.6%; P = 0.065) were comparable between the groups. Asymptomatic bacteriuria is an independent risk factor for preterm delivery.

    Investigation of HPV infection in men remains important due to its association with genital warts and anorectal cancer, as well as to the role men play in HPV transmission to their female sexual partners. Asymptomatic men (n = 43), whose sexual partners had presented cervical HPV infection, were enrolled in this study. Among the 43 men, 23 had their female partner included and tested for HPV-DNA, totaling 23 couples. HPV-DNA was detected by PCR. Type specific PCR to detect HPV 16, 18, 31, 33, 45 and 6/11 was performed. At least one type of HPV was detected in 86.0% (37/43) of the male patients and more than one HPV type was identified in 39.5% (17/43) of the samples, including high and low risk HPV. HPV-16 proved to be the most prevalent viral type in both male and female samples. Concordance of at least one viral type was observed in 56.5% (13/23) of the couples. Among couples that have shown concordance of viral types, 84.6% (11/13) of the men had the same high risk viral type presented by the female sexual partner. These data suggest that HPV infected men is an important reservoir, contributing to a higher transmission to women and maintenance of infection, and consequently, a higher risk of developing cervical cancer. HPV vaccination in men will protect not only them but will also have implications for their sexual partners. PMID:22815888

    Clinical gastrointestinal manometry studies are currently performed with multilumen water-perfused polyvinyl or strain gauge sensor solid-state catheters. A disposable catheter incorporating air-filled balloons has been developed with performance characteristics suitable for esophageal and anorectal manometry studies. Our aim was to compare esophageal and anorectal pressure measurements using this newly developed catheter with measurements obtained using standard solid-state or water-perfused catheters. Measurements of resting LES pressure, esophageal contraction amplitudes, and anorectal rest and squeeze pressures were obtained in 10 healthy volunteers using a solid-state esophageal catheter, a water-perfused anorectal catheter, and air-filled balloon esophageal and anorectal catheters. Correlation coefficient analysis demonstrated that LES pressures, esophageal contraction amplitudes, and anorectal resting and squeeze pressures were not significantly among between the different catheters. We conclude that recently developed air-filled balloon esophageal and anorectal manometry catheters provide very similar measurements of LES, esophageal body, and anorectal sphincter pressures compared to presently used manometry catheters.

    Anorectal malformation (ARM) is one of the most common congenital anomaly that requires emergency surgery in the neonatal period. ARMs are frequently associated with other life threatening congenital anomalies. Commonly associated anomalies are genito-urinary, cardiovascular, gastro-intestinal, skeletal and spinal. Alimentary tract anomalies are frequently masked by the intestinal obstruction produced by the anorectal atresia. This retrospective study was carried out to find out the incidence of associated alimentary tract atresias with ARM. In our series, out of 785 cases of high ARM, 14 cases had associated esophageal atresia (1.8%), followed by 7 cases of duodenal atresia (0.89%), and followed by pyloric atresia, jejuno-ileal atresia and colonic atresia.

  13. Dissociation of the anorectic actions of 5-HTP and fenfluramine.

    The possible peripheral anorectic actions of 5-hydroxytryptophan (5-HTP) and fenfluramine were examined in food-deprived rats. In a 1-h feeding test the peripherally acting 5-HT antagonist, xylamidine, attenuated the reductions in food intake induced by 5-HT and 5-HTP but not fenfluramine. Thus, the anorectic action of 5-HTP appears to be mediated in part by peripheral 5-HT receptors. Microstructural analyses showed that 5-HTP and fenfluramine induced decreases in eating rate and bout size. Xylamidine reversed the effect of 5-HTP on eating rate, and induced a slight increase in bout size in its own right. Therefore, the peripheral effect of 5-HTP appears to be a slowing of eating rate. No effects of xylamidine on fenfluramine induced changes in feeding were observed. The results indicate a dissociation of the anorectic effects of 5-HTP and fenfluramine based on a peripheral action of 5-HTP. The peripheral action of 5-HTP differs from the previously reported reductions in bout size and bout duration induced by 5-HT. Possible mechanisms for this difference in the peripheral actions of 5-HT and 5-HTP are discussed.

  14. The antegrade continence enema procedure and total anorectal reconstruction

    Patients may present with anal incontinence (AI) following repair of a congenital anorectal anomaly years previously, or require total anorectal reconstruction (TAR) following radical rectal extirpation, most commonly for rectal cancer. Others may require removal of their colostomy following sphincter excision for Fournier's gangrene, or in cases of severe perineal trauma. Most of the data pertaining to antegrade continence enema (the ACE or Malone procedure) comes from the pediatric literature in the management of children with AI, but also with supervening chronic constipation, where the quality of life and compliance with this technique appears superior to retrograde colonic washouts. Total anorectal reconstruction requires an anatomical or physical supplement to the performance of a perineal colostomy, which may include an extrinsic muscle interposition (which may or may not be ‘dynamized'), construction of a neorectal reservoir, implantation of an incremental artificial bowel sphincter or creation of a terminal, smooth-muscle neosphincter. The advantages and disadvantages of these techniques and their outcome are presented here. PMID:24759342

    Kabuki syndrome (KS) is a rare genetic condition characterized by a distinctive facies, intellectual disability, growth delay, and a variety of skeletal, visceral, and other anomalies, including anorectal malformations (ARMs). We present two cases of female patients with KS, diagnosed and successfully managed at our institution, one with a perineal fistula and one with a rectovestibular fistula. Our report, along with a literature review, shows that the syndrome is usually associated with “low” anomalies, with a potential for a good prognosis. Management of the anorectal anomaly in patients with KS is not essentially different from that in other nonsyndromic patients, taking into account the frequent association of the syndrome with serious congenital heart disease, which might affect the decision-making and timing of the stages of anorectal reconstruction. The frequent occurrence of learning and feeding difficulties makes establishment of toilet training and bowel management rather more challenging, requiring the expertise of a multidisciplinary team. The finding of ARMs in female patients with other characteristics of KS, although inconstant, could support the clinical suspicion for the syndrome until genetic confirmation is available, and should alert the physician for the potential of severe cardiac defects.

    The status of the erythrocyte sodium pump was evaluated in a group of patients suffering from anorexia nervosa and a group of healthy female control subjects. Anorectic patients showed significantly higher mean values of digoxin-binding sites/cell (ie, the number of Na-K-ATPase units) with respect to control subjects while no differences were found in the specific /sup 86/Rb uptake (which reflects the Na-K-ATPase activity) between the two groups. A significant correlation was found between relative weight and the number of Na-K-ATPase pump units (r = -0.66; P less than 0.0001). Anorectic patients showed lower serum T3 concentrations (71.3 +/- 53 ng/dL) with respect to control subjects (100.8 +/- 4.7 ng/dL; P less than 0.0005) and a significant negative correlation between T3 levels and the number of pump units (r = -0.52; P less than 0.003) was found. This study therefore shows that the erythrocyte Na-K pump may be altered in several anorectic patients. The authors suggest that this feature could be interrelated with the degree of underweight and/or malnutrition.

    Purpose: To explore the influence of functional changes and dosimetric parameters on specific incontinence-related anorectal complaints after prostate external beam radiotherapy and to estimate dose-effect relations for the anal wall and rectal wall. Methods and Materials: Sixty patients, irradiated for localized prostate cancer, underwent anorectal manometry and barostat measurements to evaluate anal pressures, rectal capacity, and rectal sensory functions. In addition, 30 untreated men were analyzed as a control group. In 36 irradiated patients, the anal wall and rectal wall were retrospectively delineated on planning computed tomography scans, and dosimetric parameters were retrieved from the treatment plans. Functional and dosimetric parameters were compared between patients with and without complaints, focusing on urgency, incontinence, and frequency. Results: After external beam radiotherapy, reduced anal pressures and tolerated rectal volumes were observed, irrespective of complaints. Patients with urgency and/or incontinence showed significantly lower anal resting pressures (mean 38 and 39 vs. 49 and 50 mm Hg) and lower tolerated rectal pressures (mean 28 and 28 vs. 33 and 34 mm Hg), compared to patients without these complaints. In patients with frequency, almost all rectal parameters were reduced. Several dosimetric parameters to the anal wall and rectal wall were predictive for urgency (e.g., anal D{sub mean}>38Gy), whereas some anal wall parameters correlated to incontinence and no dose-effect relation for frequency was found. Conclusions: Anorectal function deteriorates after external beam radiotherapy. Different incontinence-related complaints show specific anorectal dysfunctions, suggesting different anatomic and pathophysiologic substrates: urgency and incontinence seem to originate from both anal wall and rectal wall, whereas frequency seems associated with rectal wall dysfunction. Also, dose-effect relations differed between these complaints. This

    1993-04-01

    Asymptomatic bacteriuria occurs in 4 to 7 percent of pregnancies and is associated with the development of acute pyelonephritis, preterm labor and low-birth-weight infants. Treatment of bacteriuria prevents up to 80 percent of cases of pyelonephritis and reduces the risk of preterm delivery. All women should be screened for bacteriuria by a urine culture at the first prenatal visit. Women with bacteriuria should be treated with appropriate antibiotics and should be monitored throughout pregnancy to identify recurrences. Women with persistent bacteriuria require antibiotic suppression until delivery and urologic evaluation following delivery. Urologic evaluation during pregnancy is indicated if bacteriuria persists despite antibiotic therapy.

    The giant Lausannevirus was recently identified as a parasite of amoeba that replicates rapidly in these professional phagocytes. This study aimed at assessing Lausannevirus seroprevalence among asymptomatic young men in Switzerland and hopefully identifying possible sources of contact with this giant virus. The presence of anti-Lausannevirus antibodies was assessed in sera from 517 asymptomatic volunteers who filled a detailed questionnaire. The coreactivity between Lausannevirus and amoeba-resisting bacteria was assessed. Lausannevirus prevalence ranged from 1.74 to 2.51%. Sporadic condom use or multiple sexual partners, although frequent (53.97 and 60.35%, respectively), were not associated with anti-Lausannevirus antibodies. On the contrary, frequent outdoor sport practice as well as milk consumption were significantly associated with positive Lausannevirus serologies (p = 0.0066 and 0.028, respectively). Coreactivity analyses revealed an association between Criblamydia sequanensis (an amoeba-resisting bacterium present in water environments) and Lausannevirus seropositivity (p = 0.001). Lausannevirus seroprevalence is low in asymptomatic Swiss men. However, the association between virus seropositivity and frequent sport practice suggests that this member of the Megavirales may be transmitted by aerosols and/or exposure to specific outdoor environments. Milk intake was also associated with seropositivity. Whether the coreactivity observed for C. sequanensis and Lausannevirus reflects a common mode of acquisition or some unexpected cross-reactivity remains to be determined.

    Background Currently, anorectal manometry (ARM), which is used to diagnose defecatory disorders and identify anal weakness in fecal incontinence (FI) is generally conducted in specialized laboratories. Our aims were to compare anorectal functions measured with high resolution manometry (HRM) and a novel portable manometry device. Methods Anal pressures at rest, during squeeze, and simulated evacuation, and rectal sensation were evaluated with portable and HRM in 20 healthy women, 19 women with constipation and 11 with FI. The relationship between anal pressures measured with portable and HRM was assessed by the concordance correlation coefficient [CCC], Bland Altman test, and paired t tests. Key Results Anal pressures at rest [CCC 0.45; 95% CI 0.29, 0.58] and during squeeze [CCC 0.60; 95% CI 0.46, 0.72] measured with portable and HRM were correlated and inversely associated with the risk of FI. During simulated evacuation, the CCC for rectal pressure [0.62; 95% CI 0.43, 0.76] was greater than that for anal pressure [CCC 0.22; 95% CI 0.04, 0.39] and the rectoanal gradient [CCC 0.22; 95% CI 0.02, 0.41]. Rectal sensory thresholds for first sensation, the desire to defecate, and urgency measured by portable and HRM were also significantly correlated between techniques. For several parameters, differences between portable and HRM were statistically significant and the Bland Altman test was positive. Conclusions & Inferences Anorectal pressures and rectal sensation can be conveniently measured by portable manometry and are significantly correlated with high resolution manometry. PMID:26227262

    Straining at stool is an automatic reflex in babies and implies the presence of rectal sensation. We hypothesised that early reported rectal sensation would predict future continence in children with anorectal anomalies. The aim of this study is to determine if early straining at stool was a useful predictor of future continence in infants born with high anorectal malformations. A retrospective case note review of prospectively collected clinical information was performed with institutional review board approval. All patients with intermediate/high anorectal malformation operated on by a single surgeon from 1984 to 2010 were included. After stoma closure, parents were asked: The responses were noted within the first year of stoma closure and then all patients were followed up until they were at least 3 ½years old and continence could be assessed using the Krickenbeck outcome classification. Data were compared using Fisher's exact test and sensitivity, specificity and positive predictive value (PPV) were calculated. Forty-eight patients were included in the study. Sixteen (33%) were female (12 cloacal malformation, 3 rectovaginal fistula, 1 rectal atresia) and 32 (66%) were male (6 rectovesical fistulae, 22 rectourethral fistulae, 4 no fistula). Median follow-up was 9.7years (range 3.5-17.9). Twenty-one children were noted by their parents to exhibit early straining at stool after stoma closure. Twenty of them achieved long term continence. The sensitivity of early straining as a predictor for long term continence was 77%, specificity 95% and positive predictive value 95%. The presence of early rectal sensation reported by parents is a good predictor of long term continence. This allows more informed discussion with families in the early years of life.

    Anorectal malformation (ARM) can be divided in high, intermediate, and low forms according to the level of termination of the rectum in relation to the pubococcygeal and ischiatic lines. Patients with Down's syndrome have a high incidence of gastrointestinal anomalies, such as tracheoesophageal fistula, duodenal obstruction, annular pancreas, Hirschsprung's disease, and ARM. In these children, ARM is generally low with or without a fistula. The mode of inheritance of ARM and its genetic relation with Down's syndrome is not known, even if the association (ARM-Down's syndrome) seems not to be coincidental. We describe here a very rare case of monozygotic twins born with the association of ARM and Down's syndrome.

Asymptomatic bacteriuria as a risk factor of spontaneous preterm birth was investigated. Asymptomatic bacteriuria was more frequent in cases (p = 0.048); with a trend to be associated with preterm birth (OR: 2.39; CI 95: 1.10-5.28). From 92 preterm newborns, 21 (22.8%) had less than 32 weeks, and 71 (77.2%) +/- 32 weeks. Most frequent isolated bacteriae were: E. coli, K. pneumoniae, and P. mirabilis. Asymptomatic bacteriuria had a moderate trend to be associated with preterm birth, and infectious processes are only a part of its multiple etiologies.

    The article updates Yager's 1982 review of familial factors in the pathogenesis of anorexia nervosa. The concept of "the anorectic family", as used by Minuchin and co-workers, although adequately describing a subgroup of families with an anorectic family member, is not a valid description of the group as a whole. No constellation of familial factors has been shown to be characteristic of the families of all anorexia patients. However, certain familial factors have been shown to be over-represented-e g, the presence of eating disorders, affective illness and alcoholism among close relative. Such "serious life events" as the loss of a close relative have also been shown to be over-represented among teenage girls with anorexia nervosa. The importance of these findings in connection with history taking is discussed. Future research should be designed to identify subgroups of anorexia nervosa patients for whom familial factors are of special significance, instead of treating anorexia nervosa as a uniform entity where the same set of aetiological factors (either genetic, psychological or interpersonal) are valid for all cases.

    Lidocaine has been used for spinal anaesthesia since 1948, seemingly without causing concern until recently. This study aimed at evaluating the feasibility of performing anorectal surgery in outpatient settings with low hypobaric lidocaine doses. Three groups of 50 patients, physical status ASA I-II, undergoing anorectal surgical procedures in a prone jack-knife position, received 3 ml (18 mg), 4 ml (24 mg) or 5 ml (30 mg) of hypobaric 0.6% lidocaine. Sensory and motor blockade, time until first urination, ambulation, complications and the need for analgesics were evaluated. Patients were followed until the third post-operative day. Adequate sensory block was obtained in all patients. Blockade was significantly lower in Group 1. The level at 15 min was L(1) with 3 ml, T(11) with 4 ml and T(10) with 5 ml. Only 24 patients presented a moderate motor block. There was no hypotension, nausea or vomiting, urine retention, transitory neurological symptom or post-dural puncture headache in any patients. There was one case of bradycardia with 4 ml and two cases with 5 ml. Hypobaric lidocaine predominantly provided a sensory block after injection in the prone jack-knife position. The smallest dose (3 ml=18 mg) provides sufficient analgesia with a lesser dispersion and a shorter duration. The major advantages were haemodynamic stability and a high degree of patient satisfaction.

    Fecal incontinence is a challenging condition with numerous available treatment modalities. Success rates vary across these modalities, and permanent colostomy is often indicated when they fail. For these cases, a novel potential therapeutic strategy is anorectal transplantation (ATx). We performed four isogeneic (Lewis-to-Lewis) and seven allogeneic (Wistar-to-Lewis) ATx procedures. The anorectum was retrieved with a vascular pedicle containing the aorta in continuity with the inferior mesenteric artery and portal vein in continuity with the inferior mesenteric vein. In the recipient, the native anorectal segment was removed and the graft was transplanted by end-to-side aorta-aorta and porto-cava anastomoses and end-to-end colorectal anastomosis. Recipients were sacrificed at the experimental endpoint on postoperative day 30. Surviving animals resumed normal body weight gain and clinical performance within 5 days of surgery. Isografts and 42.9% of allografts achieved normal clinical evolution up to the experimental endpoint. In 57.1% of allografts, signs of immunological rejection (abdominal distention, diarrhea, and anal mucosa inflammation) were observed three weeks after transplantation. Histology revealed moderate to severe rejection in allografts and no signs of rejection in isografts. We describe a feasible model of ATx in rats, which may allow further physiological and immunologic studies. PMID:27488366

    Colostomy is conventionally the only treatment for anal dysfunction. Recently, a few trials of anorectal transplantation in animals have been published; however, further development of this technique is required. Moreover, it is crucial to perform this research in dogs, which resemble humans in anorectal anatomy and biology. We designed a canine anorectal transplantation model, wherein anorectal autotransplantation was performed by anastomoses of the rectum, inferior mesenteric artery (IMA) and vein, and pudendal nerves. Resting pressure in the anal canal and anal canal pressure fluctuation were measured before and after surgery. Graft pathology was examined three days after surgery. The anal blood supply was compared with that in three beagles using indocyanine green (ICG) fluorescence angiography. The anorectal graft had sufficient arterial blood supply from the IMA; however, the graft’s distal end was congested and necrotized. Functional examination demonstrated reduced resting pressure and the appearance of an irregular anal canal pressure wave after surgery. ICG angiography showed that the pudendal arteries provided more blood flow than the IMA to the anal segment. This is the first canine model of preliminary anorectal autotransplantation, and it demonstrates the possibility of establishing a transplantation model in dogs using appropriate vascular anastomoses, thus contributing to the progress of anorectal transplantation.

    Monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM) represent the earlier phases of plasma cell dyscrasias. Their definition is based on absence of end-organ damage with presence of a malignant clone that grows in the bone marrow. They share, as a common feature, the risk of progression to a symptomatic disease. MGUS progression risk is approximately 1% per year, and SMM has a risk of progression of 10% for the first 5 years which tapers off over time. The main purpose of identification of these earlier phases of the plasma cell dyscrasia was to identify patients who do not warrant treatment with chemotherapy, in whom the risk of treatment outweighs the benefit. Over the years, the definitions have not been modified to incorporate developments in imaging (magnetic resonance or positron emission and computed tomography), or genomics to identify patients at highest risk of progression within 2 years, where wait and watch might not be an appropriate option. In the absence of such definition, patients who have only a 50% chance of progression within 2 years are being offered therapy, which might also not be an optimal approach. In this review, we provide an overview of the definition, current prognostic factors, and risk stratifications in asymptomatic gammopathies, and discuss clinical trial outcomes in high-risk SMM.

Phenyl ring substituents included Cl, Br, F, CF3, CH3, OCH3, and NO2; amino group substituents included alkyl, benzyl and acetyl groups. About half of the compounds produced significant anorexia; only one of these active anorectics increased motor activity. The three most potent non-stimulant anorectics were: 1-(2-thienyl)-2-(4-chlorophenyl)ethylamine, its N-isopropyl analogue, and N-isopropyl-1-(2-thienyl)-2-(4-fluorophenyl)ethylamine.

    Cervical infections with Neisseria gonorrhoeae, Chlamydia trachomatis, and Herpes simplex virus are some of the most common sexually transmitted infections. They are often asymptomatic, and therefore the patient is at risk of developing complications, such as pelvic inflammatory disease.

    India has a large burden of individuals harboring asymptomatic gallstones. Based on Markov model decision and cost analysis, selective and concomitant cholecystectomy is recommended for special indications like hemolytic disorders and stones in endemic areas. Expectant management should be adopted in all others. The evolution of laparoscopy should not alter the indications of cholecystectomy. Since more than 90% patients with asymptomatic gallstones remain clinically "silent", routine laparoscopic cholecystectomy is not indicated for the vast majority of subjects with asymptomatic cholelithiasis. Although laparoscopic cholecystectomy has become much safer, there remains associated morbidity and mortality. The risks of the operation outweigh the complications if stones are left in-situ. Patients should be counseled about the natural history and available management options, their advantages and disadvantages, and should be part of the decision making process. Prophylactic routine cholecystectomy for asymptomatic stones is not recommended. However, laparoscopic cholecystectomy should be performed selectively or concomitantly in a specific subgroup of patients.

    Asymptomatic bacteriuria is the significant presence of bacteria in urine of an individual without symptoms. The aim of the study is to determine the prevalence of asymptomatic bacteriuria in pregnant women. This study was a prospective study conducted in the department of Obstetrics and Gynaecology at B. P. Koirala Institute of Health Sciences. The duration of the study was six months from January to June 2012. A total of 600 pregnant women were enrolled. All women were clinically identified to have no signs and symptoms of UTI. Clean catch midstream urine sample was collected from each patient into a sterile vial. The urine samples were examined for microscopic and culture sensitivity test. Out of 600 pregnant women, 52 were positive for significant bacteriuria with a prevalence rate of 8.7%. There was a significant difference in prevalence of asymptomatic bacteriuria with respect to trimester (p=0.005). Age did not show any significant difference in the prevalence of asymptomatic bacteriuria (p=0.807). There was not any significant difference in the prevalence of asymptomatic bacteriuria with respect to parity (p=0.864) and booking status (p=0.397). Escherichia coli (35%), Acinetobacter species (15%), Enterococcus species (12%) and Klebsiella pneumoniae (10%) were the common isolates. Most of the isolates were sensitive either to Nitrofurantoin, Norfloxacin or Amikacin. Asymptomatic bacteriuria is common in pregnancy. Urine culture sensitivity should be carried out routinely on all pregnant patients in order to prevent the dangerous complications associated with it.

    Patients treated with external beam radiotherapy (EBRT) may suffer from long-term anorectal adverse effects. The purpose of the present study was to assess long-term functional and structural anorectal changes in patients previously treated with EBRT for prostate cancer and to suggest the mechanism behind the development of the adverse effects. Our previously proposed RT-induced anorectal dysfunction (RT-ARD) score, developed with the intention to survey anorectal dysfunction was used to identify patients with and without anorectal symptoms. Among 309 patients surveyed with the questionnaire, we chose 23 patients with the highest RT-ARD score and 19 patients with the lowest RT-ARD score. They were investigated by multimodal rectal sensory stimulation, standard anal physiological tests. Changes of the rectal mucosa were assessed by flexible sigmoidoscopy and graded by the Vienna Rectoscopy Score (VRS). The mean follow-up time was 3.8 (range, 2.8; 8.6) years in patients with high RT-ARD and 3.8 (range, 2.6; 5.9) in patients with low RT-ARD. Endoscopic evaluation revealed higher VRS scores in patients with high RT-ARD compared to patients with low RT-ARD (p = 0.002). Patients with high RT-ARD had increased rectal sensory response to distension manifested both as volume (p = 0.006) and cross-sectional area (p = 0.04), and they had reduced maximum anal resting pressure assessed by anal manometri (p = 0.02). Long-term anorectal symptoms correlate to changes in anorectal biomechanical properties and rectal mucosal injury. Our data suggests that RT-induced long-term anorectal dysfunction is multifactorial caused by injury of the rectal mucosa and the internal anal sphincter combined with increased rectal sensitivity and reduced rectal functional capacity.

  16. Short-segment Hirschsprung's disease, cat eye syndrome, and anorectal malformation: a unique association.

    The association of Hirschsprung's disease (HD) and anorectal malformations has been reported in 2.3% to 3.4% cases. Only 2 cases have previously been published where cat eye syndrome was associated with long (but not short) segment HD. Here, we report a case where there appears to be an association among short segment HD, cat eye syndrome, and anorectal malformation, which has not previously been identified. An abnormality in chromosome 22 may be involved in the development of this association.

    AIM: To compare the efficacy and safety of acellular dermal matrix (ADM) bioprosthetic material and endorectal advancement flap (ERAF) in treatment of complex anorectal fistula. METHODS: Ninety consecutive patients with complex anorectal fistulae admitted to Anorectal Surgical Department of First Affiliated Hospital, Xinjiang Medical University from March 2008 to July 2009, were enrolled in this study. Complex anorectal fistula was diagnosed following its clinical, radiographic, or endoscopic diagnostic criteria. Under spinal anesthesia, patients underwent identification and irrigation of the fistula tracts using hydrogen peroxide. ADM was securely sutured at the secondary opening to the primary opening using absorbable suture. Outcomes of ADM and ERAF closure were compared in terms of success rate, fecal incontinence rate, anorectal deformity rate, postoperative pain time, closure time and life quality score. Success was defined as closure of all external openings, absence of drainage without further intervention, and absence of abscess formation. Follow-up examination was performed 2 d, 2, 4, 6, 12 wk, and 5 mo after surgery, respectively. RESULTS: No patient was lost to follow-up. The overall success rate was 82.22% (37/45) 5.7 mo after surgery. ADM dislodgement occured in 5 patients (11.11%), abscess formation was found in 1 patient, and fistula recurred in 2 patients. Of the 13 patients with recurrent fistula using ERAF, 5 (11.11%) received surgical drainage because of abscess formation. The success rate, postoperative pain time and closure time of ADM were significantly higher than those of ERAF (P < 0.05). However, no difference was observed in fecal incontinence rate and anorectal deformity rate after treatment with ADM and ERAF. CONCLUSION: Closure of fistula tract opening with ADM is an effective procedure for complex anorectal fistula. ADM should be considered a first line treatment for patients with complex anorectal fistula. PMID:20614483

    Owing to the tight control of methamphetamine, it is presumed that phentermine, an amphetamine-type anorectic, has recently been considered a supplement for methamphetamine abusers in Korea. In addition, the abuse of other anorectics obtained by inappropriate means has become a social issue. Hair is a useful specimen to prove chronic drug use. Therefore, an analytical method for the simultaneous detection of phentermine, phendimetrazine, amfepramone, fenfluramine, mazindol, methamphetamine, and 3,4-methylenedioxymethamphetamine (MDMA), as well as their metabolites, which covers the major amphetamines and anorectic agents in Korea, in hair was established and validated using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The drugs and their metabolites in hair were extracted using 1 % HCl in methanol and then filtered and analyzed by LC-MS/MS with electrospray ionization in positive mode. The validation results for selectivity, linearity, matrix effect, recovery, process efficiency, intra- and interassay precision and accuracy, and processed sample stability were satisfactory. The limits of detection ranged from 0.025 to 1 ng/10 mg hair and the limits of quantification were 0.25 ng/10 mg hair for every analyte except mazindol and phentermine, for which they were 10 ng/10 mg hair. The method was successfully applied for the segmental determination of selected anorectics, methamphetamine, MDMA, and their metabolites in hair from 39 drug suspects. Among the anorectics, phentermine and/or phendimetrazine were identified with or without methamphetamine in the hair samples. Closer supervision of the inappropriate use of anorectics is necessary. Also, hair analysis is useful for monitoring the abuse potential of unnoticed drugs.

  20. Asymptomatic HIV as a disability under the Americans with Disability Act.

    PubMed

    Chambers, E C

    1998-04-01

    The Americans with Disability Act (ADA) does not state whether it prohibits discrimination against individuals who are infected with HIV but asymptomatic. Some courts have held that the language of the ADA is unambiguous and does not cover asymptomatic HIV as a disability because the virus is not an "impairment" that substantially limits a "major life activity." Other courts have looked behind the statutory language and found that Congress intended to protect asymptomatic individuals with HIV because the virus impairs one's ability to procreate and/or engage in sexual relations. This Comment argues that asymptomatic individuals with HIV are indeed protected under the ADA, but that the analytic framework thus far employed by the courts is flawed. Asymptomatic HIV is a protected disability not because it is independently debilitating, but because the prejudices and fears of other may prevent HIV-infected persons from fully participating in society. The ADA was enacted to prevent exactly this type of discrimination.

  1. Asymptomatic Bacteriuria and Bacterial Interference.

    PubMed

    2015-10-01

    Asymptomatic bacteriuria is very common. In healthy women, asymptomatic bacteriuria increases with age, from <1% in newborns to 10% to 20% of women age 80 years, but is uncommon in men until after age 50 years. Individuals with underlying genitourinary abnormalities, including indwelling devices, may also have a high frequency of asymptomatic bacteriuria, irrespective of age or gender. The prevalence is very high in residents of long-term-care facilities, from 25% to 50% of women and 15% to 40% of men. Escherichia coli is the most frequent organism isolated, but a wide variety of other organisms may occur. Bacteriuria may be transient or persist for a prolonged period. Pregnant women with asymptomatic bacteriuria identified in early pregnancy and who are untreated have a risk of pyelonephritis later in pregnancy of 20% to 30%. Bacteremia is frequent in bacteriuric subjects following mucosal trauma with bleeding, with 5% to 10% of patients developing severe sepsis or septic shock. These two groups with clear evidence of negative outcomes should be screened for bacteriuria and appropriately treated. Asymptomatic bacteriuria in other populations is benign and screening and treatment are not indicated. Antimicrobial treatment has no benefits but is associated with negative outcomes including reinfection with antimicrobial resistant organisms and a short-term increased frequency of symptomatic infection post-treatment. The observation of increased symptomatic infection post-treatment, however, has led to active investigation of bacterial interference as a strategy to prevent symptomatic episodes in selected high risk patients.

    Patients with asymptomatic bile duct stones exhibit typical signs, such as elevated liver function tests, dilated bile ducts on ultrasound, a history of jaundice, or pancreatitis. The incidence of asymptomatic bile duct stones is about 10%, but up to 2% of patients show no signs of the disease. Bile duct stones can be diagnosed by using clinical judgement, scoring systems, or discriminant function tests. Which diagnostic modality is most reliable, cost-effective and safe, varies with different hospitals. Which therapy is most effective, safe and the cheapest also varies with different departments, but in the future an increasing number of departments will use the one-stage laparoscopic approach.

    Purpose: To compare the effects of (three-dimensional) 3D vs. two-dimensional (2D) radiation therapy (RT) for carcinoma of the prostate on the prevalence and pathophysiology of anorectal dysfunction. Methods and Materials: Anorectal symptoms, motility, sensory function, and anal sphincter morphology were evaluated before and up to 2 years after randomly assigned hypofractionated vs. conventionally fractionated RT in 67 patients (median age, 69 years; range, 54-82 years) with localized prostate carcinoma, using either a 3D (n = 29) or 2D (n = 38) treatment technique. Results: Anorectal symptoms increased 4 to 6 weeks after RT and persisted in both patient groups. At 2 years, abnormalities included increased stool frequency (55% vs. 53%, p = NS), urgency of defecation (72% vs. 47%, p < 0.05), fecal incontinence (28% vs. 26%, p = NS), and rectal bleeding (38% and 42%, p = NS). Anorectal motility and sensory function deteriorated after RT in both groups with reductions in basal anal pressures, anal pressures in response to squeeze, rectal compliance, and rectal volumes associated with the desire to defecate. External but not internal sphincter thickness changed in the treatment groups although in different directions. However no differences in motility or sensory function were detected between the groups. Baseline anorectal motility but not treatment technique and the hypofracionated schedule were of independent prognostic significance for anorectal motor dysfunction and rectal bleeding respectively at 2 years. Conclusion: The prevalence and pathophysiology of anorectal dysfunction 2 years after RT for prostate carcinoma was largely independent of the treatment techniques used in this study.

    Three-dimensional high-definition anorectal manometry (3D-HDAM) is used to assess anal sphincter function; it determines profiles of regional pressure distribution along the length and circumference of the anal canal. There is no consensus, however, on the best way to analyze data from 3D-HDAM to distinguish healthy individuals from persons with sphincter dysfunction. We developed a computer analysis system to analyze 3D-HDAM data and to aid in the diagnosis and assessment of patients with fecal incontinence (FI). In a prospective study, we performed 3D-HDAM analysis of 24 asymptomatic healthy subjects (control subjects; all women; mean age, 39 ± 10 years) and 24 patients with symptoms of FI (all women; mean age, 58 ± 13 years). Patients completed a standardized questionnaire (FI severity index) to score the severity of FI symptoms. We developed and evaluated a robust prediction model to distinguish patients with FI from control subjects using linear discriminant, quadratic discriminant, and logistic regression analyses. In addition to collecting pressure information from the HDAM data, we assessed regional features based on shape characteristics and the anal sphincter pressure symmetry index. The combination of pressure values, anal sphincter area, and reflective symmetry values was identified in patients with FI versus control subjects with an area under the curve value of 1.0. In logistic regression analyses using different predictors, the model identified patients with FI with an area under the curve value of 0.96 (interquartile range, 0.22). In discriminant analysis, results were classified with a minimum error of 0.02, calculated using 10-fold cross-validation; different combinations of predictors produced median classification errors of 0.16 in linear discriminant analysis (interquartile range, 0.25) and 0.08 in quadratic discriminant analysis (interquartile range, 0.25). We developed and validated a novel prediction model to analyze 3D-HDAM data. This

    The detection of asymptomatic bacteriuria in preadolescent girls may be important due to its effects on subsequent pregnancies. To describe the prevalence of asymptomatic bacteriuria in preadolescent girls and the value of the nitrite test for screening. Cross-sectional study in girls aged 9 to 13 years. Bacteriuria was defined as the growth of > 100,000 CFU/mL in 2 consecutive urine specimens. Three hundred and twenty seven girls were included. Asymptomatic bacteriuria was found in 7 girls, so the prevalence was 2.1% (95% CI, 1 to 4.4%). Escherichia coli was the isolated agent in all the cases. Focused interrogatory found history of urinary symptoms in 6 girls. The utility values of the nitrite test were: sensitivity, 1; specificity, 0.9; positive likelihood ratio, 10; and negative predictive value, 1. The prevalence of asymptomatic bacteriuria in preadolescent girls in this Mexican study is similar to the one reported internationally; it is reasonable to consider its early detection to avoid its effects on future pregnancies. Nitrite test seems to be good for screening.

    H-type anorectal malformations (ARM) are extremely rare in males. Herein, we have described our experience of managing this variety. From September 1993 to February 2009, seven boys with H-type ARM were managed in the Department of Pediatric Surgery, Chittagong Medical College and Hospital, Chittagong, Bangladesh. Clinical features, operative procedures and outcomes were analyzed. Age ranged from 1 day to 4 years. The passage of meconium was seen in urine of four boys, through ectopic openings in the perineum in three boys. One patient had a round worm passing through an ectopic opening. Three boys' perineum showed meconium dots/streak along scrotal raphe. Anus was absent in all. Two patients had rectopenilurethral (RPU) and rectoscrotal (RS) fistula; two boys had anoscrotal and anoperineal fistula; one boy had pinhole anus with RS and RPU fistula. One boy had rectoperineal and RS fistula. One patient had rectobulbar urethral fistula with meconium filled chamber between the two hemiscrotum. Two boys had associated anomalies. Five boys had primary procedure with anterior sagittal approach-anoplasty (ASAP) and anorectoplasty (ASARP). Two patients had pelvic colostomy and ASARP in one and PSARP in one. One patient died postoperatively. One boy developed anal stenosis and needed redo. Five children have regular bowel movements and they are growing well. Thorough clinical examination may identify the anatomical variations of male H-type ARM, and for the treatment of which primary ASAP or ASARP gives good results.

    Objective Anorectal malformations (ARMs) are one of the commonest anomalies in neonates. Both laparoscopically assisted anorectal pull-through (LAARP) and posterior sagittal anorectoplasty (PSARP) can be used for the treatment of ARMs. The aim of this systematic review and meta-analysis is to compare these two approaches in terms of intraoperative and postoperative outcomes. Methods MEDLINE, Embase, Web of Science and the Cochrane Library were searched from 2000 to August 2016. Both randomized and non-randomized studies, assessing LAARP and PSARP in pediatric patients with high/intermediate ARMs, were included. The primary outcome measures were operative time, length of hospital stay and total postoperative complications. The second outcome measures were rectal prolapse, anal stenosis, wound infection/dehiscence, anorectal manometry, Kelly's clinical score, and Krickenbeck classification. The quality of the randomized and non-randomized studies was assessed using the Cochrane Collaboration's Risk of Bias tool and Newcastle-Ottawa scale (NOS) respectively. The quality of evidence was assessed by GRADEpro. Results From 332 retrieved articles, 1, 1, and 8 of randomized control, prospective and retrospective studies, respectively, met the inclusion criteria. The randomized clinical trial was judged to be of low risk of bias, and the nine cohort studies were of moderate to high quality. 191 and 169 pediatric participants had undergone LAARP and PSARP, respectively. Shorter hospital stays, less wound infection/dehiscence, higher anal canal resting pressure, and a lower incidence of grade 2 or 3 constipation were obtained after LAARP compared with PSARP group values. Besides, the LAARP group had marginally less total postoperative complications. However, the result of operative time was inconclusive; meanwhile, there was no significant difference in rectal prolapse, anal stenosis, anorectal manometry, Kelly's clinical score and Krickenbeck classification.

    Colonic elongation is reported as a possible cause for slow colonic transit, as it is observed in patients with slow-transit constipation (STC). This study aimed to determine the frequency of colonic elongation in children with STC or anorectal retention using radioimaging. We hypothesized that transverse colon elongation may occur in patients with STC, whereas sigmoid colon elongates in patients with anorectal retention. Nuclear transit scintigraphy performed for chronic constipation (1999-2011) was analyzed qualitatively for elongated transverse colon or sigmoid colon. Three major colonic transit patterns were identified: slow transit in the proximal colon (STC), normal proximal colonic transit with anorectal retention (NT-AR), and rapid proximal transit ± anorectal retention (RT). χ(2) Test was used for statistical analysis (P < .05 significant). From 1999 to 2011, 626 children had nuclear transit scintigraphy. Transverse colon elongation occurred more frequently in STC (73/322, or 23%) compared with NT-AR (9/127, or 7%) and RT (5/177, or 3%; P < .0001). Sigmoid colon elongation was equally common in NT-AR (8/127, or 6%) compared with RT (10/177, or 6%) and STC (14/322, or 4%; P < .9). Transverse colon elongation is more common in STC (23%), whereas sigmoid colon elongation is not more common in anorectal retention. Colonic elongation may be the cause or the result of the underlying slow colonic transit. Crown Copyright © 2012. Published by Elsevier Inc. All rights reserved.

    Although numerous studies have described the anorectic, cardiovascular, and behavioral effects of phenthylamines, a comparison of the pharmacological concordance of these properties in a single species is needed. The objectives of this study were to compare the anorectic potency of 13 phenethylamines following po administration with their effects on spontaneous locomotor activity (SLA) and blood pressure (BP) in vivo and with amphetamine receptor affinity in vitro. The anorectic potencies (ED 50) ranged from 12 umol/kg (fenfluramine) to over 400 umol/kg (d-norephedrine and 1-pseudoephedrine). d-Amphetamine, phentermine, and d-norpseudoephedrine were among the most active and 1-pseudoephedrine and 1-nor-ephedrine the least active in increasing SLA. 1-Norephedrine, and d-norpseudoephedrine were the most active increasing BP while d-norephedrine produced a weak vasodepressor effect. A significant correlation (r = .80) was observed between anorectic potency and affinity (IC 50) for /sup 3/H-amphetamine binding sites in the hypothalamus. However, the stereoselectivity between pairs of enantiomers to inhibit food consumption was not paralleled in binding affinity. The rank order of concordance of phenethylamines in anorectic activity was most apparent in behavior and binding affinity.

    2010-01-01

    Insulin detemir is a novel human insulin analog that does not show the usual propensity for weight gain in diabetic patients. We speculated that this beneficial effect could be due to insulin detemir exerting stronger anorectic effects within the brain than other insulins. To study the central effects of regular human insulin and insulin detemir on food intake, the present study was undertaken. We used acute intracerebroventricular insulin injections to compare food intake and body weight in rats fed ad libitum. Contrary to previously published data, we found that neither regular human insulin (8 or 32 mU) nor insulin detemir (1,290 pmol) reduced food intake in this model. Melanotan-II was also injected intracerebroventricularly as a positive control, and significantly reduced food intake and body weight, suggesting that our intracerebroventricular model is able to show anorectic effects. A series of experiments was therefore conducted in which different set-ups were tested to investigate which factors would be required to produce the reported anorectic effect of intracerebroventricular insulin. Although we varied rat strain, stereotactic coordinates, formulations of insulin and vehicle, dose, volume, and time of injection, the anorectic effect of intracerebroventricular insulin could not be replicated. Therefore, we suggest that acute intracerebroventricularly injected insulin does not robustly inhibit food intake in rats. Based on our results, the acute intracerebroventricular injection procedure may not be a preferred method for studying the central anorectic effects of insulin in rats. Instead, administrations over time or locally in hypothalamic nuclei might be recommended.

    Perianal Paget's disease (PPD) represents a skin neoplasm which can be either primary or secondary to carcinoma from an adjacent internal organ. PPD with underlying colorectal adenocarcinoma is usually looked upon as a secondary disease. We report a rare case of co-associated PPD and anorectal adenocarcinoma. The PPD was found to be located near the anorectal adenocarcinoma with normal tissues between them. Immunohistochemical stains demonstrated that the Paget's cells were CK7+/GCDFP-15–/CK20–/MUC2–/CDX2–, whereas the anorectal adenocarcinoma was shown to be CK7+/GCDFP-15–/CK20+/MUC2+/CDX2+. This immunological phenotypic profile supported the notion that PPD and anorectal adenocarcinoma were of different origins, but could not define the exact origins of PPD. In our determination, this case was a primary PPD with anorectal adenocarcinoma. PPD remains a heterogeneous and complex pathology, and additional studies are required to differentiate between the various possible origins. PMID:24932167

    High resolution anorectal manometry (HRM) is an increasingly common procedure performed in pediatric patients to rule out Hirschsprungs as well as assess anorectal function and sensation. The purpose of this study was to evaluate anxiety of patients and their parents associated with HRM. Pre-procedural anxiety was assessed by standardized questionnaire in all parents and children over the age of 8 and observed behavioral distress was recorded by the attending pediatric gastroenterologist. Thirty-five children (mean age = 7.2 yrs, +- 2.8) and their parents completed the study. Patient anxiety was found to be markedly elevated. Observed behavioral distress was elevated compared to more invasive procedures. Self-reported parental anxiety was comparable to adults undergoing endoscopic procedures themselves. Despite the low risk of this procedure, healthcare providers should be aware of the high levels of anxiety and distress that occur in patients and their parents associated with anorectal manometry.

    Despite recent methodological advancement of the practical pain medicine, many cases of the chronic anorectal pain have been intractable. A 54-year-old female patient who had a month history of a constant severe anorectal pain was referred to our clinic for further management. No organic or functional pathology was found. In spite of several modalities of management, such as medications and nerve blocks had been applied, the efficacy of such treatments was not long-lasting. Eventually, she underwent temporary then subsequent permanent sacral nerve stimulation. Her sequential numerical rating scale for pain and pain disability index were markedly improved. We report a successful management of the chronic intractable anorectal pain via permanent sacral nerve stimulation. But further controlled studies may be needed. PMID:20552076

    Melanoma develops from melanocytes and typically occurs on the skin and mucosa with a high degree of malignancy. Intensive local invasion and distant metastasis of melanoma result in poor patient prognosis, owing to frequent metastases to the lungs, bones, brains, and other parts of the body. In the present study, we report a case of anorectal melanoma in a 56-year-old woman who was admitted to our hospital because of local recurrence 9 months after local resection. She subsequently underwent radical surgery. Metastasis to the left breast occurred within 4 months after radical surgery. Metastasis of anorectal melanoma to the breast is very rare. In the present case report and literature review, we analyzed the clinical manifestation, diagnosis, and treatment of anorectal melanoma metastatic to the breast. PMID:27563250

    The integration of sexual health into the health care services is important. In women attending urogynecological clinics, the urinary function, anorectal function, and anatomical defects are more often evaluated than those related to sexual activity and function. A group of experts in urogynecology, sexuality, and patient reported outcome development, met in a roundtable with the final objective of reviewing what is currently available and what is needed to accurately evaluate sexual function in women with pelvic floor dysfunction. An article was prepared for each of the issued presented during the roundtable and combined into this supplement. This article is a summary of all articles included in this supplement. The pathophysiology of sexual dysfunction as related to pelvic floor disorders has not been well established. Sexuality questionnaires and scales play an integral role in the diagnosis and treatment of female sexual dysfunction. The Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ) is the only validated female sexual function questionnaire specifically developed to assess sexual function in women with urinary incontinence and/or pelvic organ prolapse; however, the PISQ does not screen for sexual activity. The effects of treatments for pelvic floor problems on sexual function have received little attention. There is a need for a validated sexual function measure that evaluates not only the impact of pelvic floor dysfunction on sexual function but also the impact on sexual activity.

    This systematic review aims to give an overview of available evidence concerning the influence of anorectal malformations (ARM) on fertility. We conducted a search in PubMed, EMBASE and Cochrane Library conformed to the PRISMA standards. All studies reporting on fertility and ARM were included. 2,905 studies were identified. Based on title, abstract and full text, nine articles on 429 patients remained to answer the research question. Childbirth rate was the only reported outcome parameter to describe fertility. An overall childbirth rate of 27 % (range 0-57 %) was found. Mean age at time of study ranged from 23 to 35 years. There was no statistical significant difference in childbirth rate between female and male patients, based on seven studies (p = 0.45). Patients with a more complex type of ARM (imperforated anus without fistula, rectourethral bulbar and prostatic fistulas, rectobladderneck fistulas and cloacal malformations) had a lower childbirth rate compared to healthy controls, whereas in patients with a less complex ARM (rectoperineal or rectovestibular fistula) the childbirth rate was similar to healthy controls. Patients with a more complex type of ARM had a significant lower childbirth rate than patients with a less complex type of ARM (18 vs 47 %, respectively) (p = 0.0001). When further dividing these patients by gender, this difference was only seen in female patients (p = 0.04). In patients with a more complex type of ARM a lower childbirth rate was found compared to healthy controls and patients with a less complex type of ARM. The latter was only seen in female patients. However, conclusions concerning fertility in ARM patients have to be taken with caution due to limited quality of the studies. Further investigation is recommended.

    To assess the long-term outcome of surgery for anorectal malformations (ARM) from the patient's perspective. One hundred and sixty seven children were operated for ARM between 1982 and 2000. Disease impact questionnaires to assess both clinical and psychological outcomes were sent to 137 eligible families. Statistical analysis was performed using SPSS version 11.5. The response rate was 61% (n=84). Sixty six percent had soiling. There was no significant difference in the incidence of soiling between genders or between the younger child and adolescent. Soiling was significantly increased in high (86%) and intermediate (79%) compared to low (43%) malformation (P=0.001). Constipation was seen in 62% and abdominal pain in 49%, with no significant difference between malformation levels. Overall, 71% had associated anomalies. Although 44% had a documented urological abnormality, clinical significant problems were seen in only 30%. Eighty percent of the children had one or more behavioural problems and 15% expressed suicidal thoughts. ARM had a negative impact on the social life of the child in 52% and on family functioning in 50%. Soiling (P=0.000), presence of associated anomalies (P=0.001), constipation (P=0.005), level of ARM (P=0.015) and abdominal pain (P=0.039) correlated significantly with psychosocial morbidity. Despite these findings, 62% of adolescents and 71% of children below 12 years with their parents reported above average global hopefulness score, remaining hopeful for the future. Children with ARM have ongoing physical and social morbidity, indicating the need for continuing multidisciplinary review and support to optimise their quality of life.

    During sepsis, catabolism of proteins and associated changes in plasma amino acids occur. Tryptophan and tyrosine, and their derivatives serotonin (5-HT) and dopamine (DA), influence hypothalamic feeding-related areas and are associated with the onset of anorexia. We hypothesized that anorexia of sepsis is associated with changes in serotonin and dopamine in the ventromedial nucleus (VMN) of the hypothalamus. The aim of this study was to test our hypothesis by measuring intra-VMN changes of these two neurotransmitters at the onset of anorexia during sepsis. Fischer 344 male rats had an intracerebral guide cannula stereotaxically implanted into the VMN. Ten days later, in awake, overnight-food-deprived rats, a microdialysis probe was inserted through the in situ VMN cannula. Two hours thereafter, serial baseline serotonin and dopamine concentrations were measured. Then cecal ligation and puncture to induce sepsis or a control laparotomy was performed under isoflurane anesthesia. VMN microdialysis samples were serially collected every 30 min for 8 h after the surgical procedure to determine 5-HT and DA changes in response to sepsis. During the hypermetabolic response to sepsis, a strong association occurred between anorexia and a significant reduction of VMN dopamine concentration (P < 0.05; constant rate of dopamine decrease in the Study group of 0.99 pg per 2 h); no changes occurred in 5-HT in association with anorexia of sepsis. Six hours after operation, a single meal was offered for 20 min to assess the response of neurotransmitters to food ingestion. Food intake was minimal in anorectic septic rats (mean size of the after food-deprived meal in the Septic group was 0.03+/-0.01 g, that of the Control group was 1.27+/-0.14 g; P = 0.0001), while Control rats demonstrated anticipated changes in neurotransmitters in response to eating. We conclude that the onset of anorexia in septic rats is associated with a reduction in VMN dopamine.

    Anorectal biofeedback therapy (BFT) is a safe and effective treatment in patients with constipation. Given the high prevalence of constipation and therefore high demand for BFT, there is a need to prioritise patients. To explore clinical features and anorectal physiology which predict success or failure of BFT and to derive a statistical model which helps to predict the success of BFT. A total of 102 patients with constipation referred for BFT were evaluated. All patients underwent comprehensive clinical and anorectal function assessment, including balloon expulsion testing. The BFT protocol consisted of a comprehensive 6-weekly visit programme comprising instruction on toilet behaviour and abdominal breathing, achieving adequate rectal pressure and anal relaxation, and balloon expulsion and rectal sensory retraining. Success of BFT was based on an improvement in global bowel satisfaction. Harder stool consistency (P=0.009), greater willingness to participate (P<0.001), higher resting anal sphincter pressure (P=0.04) and prolonged balloon expulsion time (P=0.02) correlated with an improvement in bowel satisfaction score. A longer duration of laxative use (P=0.049) correlated with no improvement in bowel satisfaction score. Harder stools, shorter duration of laxative use, higher straining rectal pressure and prolonged balloon expulsion independently predicted successful BFT. A model (S(i) = (p)∑ β(j)X(ij), where β represents a regression coefficient, X is a given predictive variable and S(i) is the weighted index score for each individual) incorporating these four variables enabled prediction of successful BFT, with sensitivity and specificity of 0.79 and 0.81, respectively. Important clinical and anorectal physiological features were found to be associated with outcome of anorectal biofeedback therapy in patients with constipation. This information and the predictive model will assist clinicians to prioritise patients for anorectal biofeedback therapy. © 2011

    BACKGROUND & AIMS Disordered defecation is attributed to pelvic floor dyssynergia. However, clinical observations indicate a spectrum of anorectal dysfunctions. The extent to which these disorders are distinct or overlap is unclear; anorectal manometry might be used in diagnosis, but healthy persons also can have abnormal rectoanal pressure gradients during simulated evacuation. We aimed to characterize phenotypic variation in constipated patients through high-resolution anorectal manometry. METHODS We evaluated anorectal pressures, measured with high-resolution anorectal manometry, and rectal balloon expulsion time in 62 healthy women and 295 women with chronic constipation. Phenotypes were characterized by principal components analysis of high-resolution anorectal manometry. RESULTS Two healthy persons and 71 patients had prolonged (>180 s) rectal balloon expulsion time. A principal components logistic model discriminated healthy people from patients with prolonged balloon expulsion time with 75% sensitivity and a specificity of 75%. Four phenotypes discriminated healthy people from patients with abnormal balloon expulsion times; 2 phenotypes discriminated healthy people from those with constipation but normal balloon expulsion time. Phenotypes were characterized based on high anal pressure at rest and during evacuation (high anal), low rectal pressure alone (low rectal) or low rectal pressure with impaired anal relaxation during evacuation (hybrid), and a short anal high-pressure zone. Symptoms were not useful for predicting which patients had prolonged balloon expulsion times. CONCLUSIONS Principal components analysis of rectoanal pressures identified 3 phenotypes (high anal, low rectal, and hybrid) that can discriminate among patients with normal and abnormal balloon expulsion time. These phenotypes might be useful to classify patients and increase our understanding of the pathogenesis of defecatory disorders. PMID:23142135

    Purpose: To evaluate the role of colonic motility in the pathogenesis of anorectal symptoms and dysfunction after radiotherapy (RT) for carcinoma of the prostate. Patients and Methods: Thirty-eight patients, median age 71 (range, 50-81) years with localized prostate carcinoma randomized to one of two radiation dose schedules underwent colonic transit scintigraphy and assessment of anorectal symptoms (questionnaire), anorectal function (manometry), and anal sphincteric morphology (endoanal ultrasound) before and at 1 month and 1 year after RT. Results: Whole and distal colonic transit increased 1 month after RT, with faster distal colonic transit only persisting at 1 year. Frequency and urgency of defecation, fecal incontinence, and rectal bleeding increased 1 month after RT and persisted at 1 year. Basal anal pressures remained unchanged, but progressive reductions occurred in anal squeeze pressures and responses to increased intra-abdominal pressure. Rectal compliance decreased progressively in the patients, although no changes in anorectal sensory function ensued. Radiotherapy had no effect on the morphology of the internal and external anal sphincters. Distal colonic retention was weakly related to rectal compliance at 1 month, but both faster colonic transit and reduced rectal compliance were more frequent with increased fecal urgency. At 1 year, a weak inverse relationship existed between colonic half-clearance time and frequency of defecation, although both faster whole-colonic transit and reduced rectal compliance occurred more often with increased stool frequency. Conclusion: Colonic dysmotility contributes to anorectal dysfunction after RT for carcinoma of the prostate. This has implications for improving the management of anorectal radiation sequelae.

    Sexually transmitted diseases (STDs) constitute a major health burden in the United States, causing pelvic inflammatory disease, ectopic pregnancy, infertility, chronic pelvic pain, genital lesions, genital neoplasms, adverse pregnancy outcomes, immune system dysfunction, liver disease, and even death. STDs disproportionately affect adolescents and young adults. Of the estimated 15 million STDs that occur annually each year in the United States, 4 million are among adolescents and 6 million among young adults. The current epidemic is complicated by the high asymptomatic carrier state associated with most STDs and the inadequate protection of condoms in preventing transmission. Sexually active individuals, particularly adolescents, must be educated on the ramifications of early onset of sexual activity and the health consequences of multiple sexual partners.

    Introduction Anorectal malformations (ARMs) are a complex collection of congenital disorders of the anus, rectum, and genitourinary system with possible active morbidities beyond adolescence. Aims To create the first evidence-based inclusive transition risk assessment score (TRAS) to stratify health care needs and interventions in teenagers with ARM transitioning to adult health care. Method MEDLINE, EMBASE, and the Cochrane Library were searched electronically for original articles containing published scoring systems evaluating children with ARM from January 1, 1990 to December 31, 2013. Current published scoring systems identified were weighted to create a novel score (TRAS) to objectively assess the most common active problems present in teenagers with ARM: fecal, urinary, and sexual functions; quality of life; and psychosocial well-being. The TRAS was applied to patients visiting our tertiary anorectal clinic in the period from January 2014 to March 2016. Patients were rescored on each visit to the clinic. Results Total 21 separate scoring systems were identified in the literature, with 3 scoring systems incorporated into the TRAS. The score divided patients into "low" (0-4), "medium" (5-10), and "high" (11-35) risk categories. The TRAS was used to assess 14 adolescents with ARMs during the study period; 14 patients had a single TRAS, 7 had two TRAS, and 3 had three TRAS assessments. At first visit 14 patients with a median age of 13 were assessed with TRAS ranging from 2 to 13 (M = 5, SD 3.33, 95% CI 3.08-7.68). At second visit seven patients with a median age of 15 were assessed with TRAS ranging from 2 to 12 (M = 6.43, SD 3.51, 95% CI 3.19-9.67). At third visit three patients with a median age of 16 were assessed with TRAS ranging from 6 to 12 (M = 8.33, SD 3.21, 95% CI 0.35-16.32). There was no significant difference (p > 0.05) between a patient's TRAS at different visits. Conclusion Preliminary data suggest that the TRAS is a

    Asymptomatic bacteriuria (ASB) is a common finding and frequently detected in premenopausal nonpregnant women, institutionalized patients, patients with diabetes mellitus, and the ambulatory elderly population. Despite clear recommendations regarding diagnosis and management of ASB in these populations from the Infectious Diseases Society of America (IDSA), there remains an alarming rate of antimicrobial overuse. This article reviews definitions of ASB, epidemiology of ASB, literature surrounding ASB in diabetic patients, risk factors of ASB, microbiologic data regarding bacterial virulence, use of ASB strains for treatment of symptomatic urinary tract infection, and approaches to addressing translational barriers to implementing IDSA recommendations regarding diagnosis and management of ASB.

    Colostomy is conventional treatment for anal dysfunction. Recently, a few trials of anorectal transplantation in animals have been published as a potential alternative to colostomies; however, further development of this technique is required. In this study, we utilized a canine model of anorectal transplantation, evaluated the patency of our microsurgical anastomoses, and assessed the perfusion of the transplanted anus. We designed a canine anorectal transplantation model, wherein anorectal autotransplantation was performed in four healthy beagle dogs by anastomoses of the lower rectum, the bilateral pudendal arteries (PAs) and veins (PVs), and pudendal nerves (PNs). Postoperative graft perfusion was measured by indocyanine green (ICG) angiography and histological examination. The length of the anorectal graft including perianal skin, anal sphincter muscle, bilateral PAs, PVs, and PNs was 4.9 ± 0.3 cm. All diameters of the PAs, PVs, and PNs were large enough to be microscopically anastomosed. Both ICG angiography and histological examination demonstrated good graft perfusion, except for one case that lead to venous congestion. These results show that anastomosis of the bilateral PAs, PVs, and PNs is required for anorectal transplantation. This is the first successful report of canine anorectal autotransplantation.

    BACKGROUND: Transanal endoscopic microsurgery is a minimally invasive technique that allows full-thickness resection and suture closure of the defect for large rectal adenomas, selected low-risk rectal cancers, or small cancers in patients who have a high risk for major surgery. Our aim, in the given prospective study was to report our initial clinical experience with TAMIS, and to evaluate its effects on postoperative anorectal functions. MATERIALS AND METHODS: In 10 patients treated with TAMIS for benign and malignant rectal tumors, preoperative and postoperative anorectal function was evaluated with anorectal manometry and Cleveland Clinic Incontinence Score. RESULTS: The mean distance of the tumors from the anal verge was 5.6 cm, and mean tumor diameter was 2.6 cm. All resection margins were tumor free. There was no difference in preoperative and 3-week postoperative anorectalmanometry findings; only mean minimum rectal sensory volume was lower at 3 weeks after surgery. The Cleveland Clinic Incontinence Score was normal in all patients except one which resolved by 6 weeks after surgery.The mean postoperative follow-up was 28 weeks without any recurrences. CONCLUSION: Transanal minimally invasive surgery is a safe and effective procedure for treatment of rectal tumors and can be performed without impairing anorectal functions. PMID:26622116

    High-resolution anorectal manometry (HR-ARM) and high-definition anorectal manometry (HD-ARM) catheters have closely spaced water-perfused or solid state circumferentially-oriented pressure sensors that provide much better spatiotemporal pressurization than non-high resolution catheters. This is a comprehensive review of HR-ARM and HD-ARM anorectal manometry catheter systems, the methods for conducting, analyzing, and interpreting HR-ARM and HD-ARM, and a comparison of HR-ARM with non-high resolution anorectal manometry. Compared to non-high resolution techniques, HR-ARM and HD-ARM studies take less time and are easier to interpret. However, HR-ARM and HD-ARM catheters are more expensive and fragile and have a shorter lifespan. Further studies are needed to refine our understanding of normal values and to rigorously evaluate the incremental clinical utility of HR-ARM or HD-ARM compared to non-high resolution manometry.

    N-acyl-phosphatidylethanolamine is a precursor phospholipid for anandamide, oleoylethanolamide, and other N-acylethanolamines, and it may in itself have biological functions in cell membranes. Recently, N-palmitoyl-phosphatidylethanolamine (NAPE) has been reported to function as an anorectic hormone secreted from the gut and acting on the brain (Gillum et al., [5]). In the current study, two of our laboratories independently investigated whether NAPE metabolites may be involved in mediating the anorectic action of NAPE i.p. injected in mice. Thus, the anorectic activity of a non-hydrolysable NAPE analogue, having ether bonds instead of ester bonds at sn1 and sn2 was compared with that of NAPE in molar equivalent doses. Furthermore, the anorectic effect of NAPE in NAPE-hydrolysing phospholipase D knockout animals was investigated. As negative controls, the NAPE precursor phosphatidylethanolamine and the related phospholipids phosphatidylcholine and phosphatidic acid were also tested. All compounds except one were found to inhibit food intake, raising the possibility that the effect of NAPE is non-specific.

    Anorectal malformations are rare occurrences characterized by the absence or abnormal localization of the anus. Clinical manifestations can vary from mild forms that require only minor surgery to more complicated cases that must be managed with multi-staged surgery. In this report, our aim is to present the clinical characteristics, management, and treatment outcome of an adult patient with an anorectal malformation with a vestibular fistula that was successfully repaired by posterior sagittal anorectoplasty (PSARP) and to discuss the case in the light of the relevant literature. We also would like to underline the fact that primary anorectal malformations can, although rarely, be observed in adult patients. A 26-year-old female patient presented with an imperforate anus and constipation with feces passing through a fistula located at the distal part of her vagina. She was continent for solid feces, but had leakage of flatus and fecal soiling. She also had concurrent left renal agenesis. A posterior sagittal anorectoplasty was successfully performed without a colostomy. The patient was discharged uneventfully on the postoperative 8th day. The patient was fully continent during a control visit after seven years of follow-up. Posterior sagittal anorectoplasty is a technique that can be successfully used in adult patients with anorectal malformations.

    The purpose of this study is to evaluate the predictive capability of anorectal physiologic tests for unfavorable outcomes prior to the initiation of biofeedback therapy in patients with dyssynergic defecation. We analyzed a total of 80 consecutive patients who received biofeedback therapy for chronic idiopathic functional constipation with dyssynergic defecation. After classifying the patients into two groups (responders and non-responders), univariate and multivariate analyses were performed to determine the predictors associated with the responsiveness to biofeedback therapy. Of the 80 patients, 63 (78.7%) responded to biofeedback therapy and 17 (21.3%) did not. On univariate analysis, the inability to evacuate an intrarectal balloon (P=0.028), higher rectal volume for first, urgent, and maximal sensation (P=0.023, P=0.008, P=0.007, respectively), and increased anorectal angle during squeeze (P=0.020) were associated with poor outcomes. On multivariate analysis, the inability to evacuate an intrarectal balloon (P=0.018) and increased anorectal angle during squeeze (P=0.029) were both found to be independently associated with a lack of response to biofeedback therapy. Our data show that the two anorectal physiologic test factors are associated with poor response to biofeedback therapy for patients with dyssynergic defecation. These findings may assist physicians in predicting the responsiveness to therapy for this patient population. PMID:20592899

    Purpose For several decades, the low anterior resection (LAR) with total mesorectal excision (TME) has been the gold standard for treating patients with rectal cancer. Up to 90% of patients undergoing sphincter-preserving surgery will have changes in bowel habits, so-called 'anterior resection syndrome.' This study examined patients' continence after a LAR for the treatment of rectal cancer. Methods This prospective study was performed between September 2014 and August 2015 at the National Cancer Institute and included 30 patients who underwent anorectal manometry preoperatively and at 3 and 4 months after a LAR, but 10 were excluded from further evaluation for various reasons. Wexner score was recorded preoperatively and 4 months after LAR (1 month after ileostomy repair). Results Postoperatively, 70% of patients complained of some degree of soiling (incontinence to liquid stool), and 30% experienced urgent defecation. Four months after surgery, these symptoms had somewhat abated. The anal resting pressure and the maximum squeezing pressure did not change significantly. Rectal capacity and compliance were reduced in all patients. The majority of patients demonstrated manometric anorectal changes and clinical anorectal function disorders during the first 4 months after surgery. The Wexner scores and the manometric findings showed no correlation. Conclusion Many patients undergoing a LAR with TME for the treatment of rectal cancer experience some degree of incontinence postoperatively. Anorectal manometry may be used as an additional tool for evaluating problems with continence after a LAR. No correlation between the Wexner score and the manometric findings was observed.

    Rectal prolapse has been reported after laparoscopic assisted anorectal pullthrough in children with anorectal malformation. We report our clinical outcome and study the application of an anchoring stitch to tack the rectum to the presacral fascia and the occurrence of rectal prolapse. A retrospective review of all children who had undergone laparoscopic assisted anorectal pullthrough for anorectal malformation from 2000 to 2015 was performed. Patients were divided into two groups (group I: with anchoring stitch, group II: without anchoring stitch). Outcome measures including rectal prolapse, soiling, voluntary bowel control, and constipation, and Kelly Score were analyzed. There were thirty-four patients (group I, n=20; group II, n=14) undergoing laparoscopic assisted anorectal pullthrough during the study period. The median follow up duration for group I and group II was 60months and 168months, respectively. All patients had stoma performed prior to the operation. Both groups consisted of patients with high type (30% vs 57%, p=0.12) and intermediate type (70% vs 43%, p=0.12) anorectal malformation. Seven (35%) patients in group I and 3 (21%) in group II had concomitant vertebral and spinal cord pathologies (p=0.408). The mean operative time was significantly shorter in group I (193±63min vs 242±49min, p=0.048). Rectal prolapse occurred less in group I, 4 (20%) vs 9 (64%) patients in group II and was statistically significant (p=0.008). Median time to development of rectal prolapse was 7months in group I and 5months in group II (p=0.767). Mucosectomy was performed in 15% of group I and 36% of group II (p=0.171). Soiling occurred less in group I (55% vs 79%, p=0.167). Voluntary bowel control (85% vs 93%, p=0.499) and constipation (55% vs 64%, p=0.601) were comparable in both groups. 75% in group I and 71% in group II achieved a Kelly score of 5 or above (p=0.823). Our study showed application of anchoring stitch reduces rectal prolapse and soiling in laparoscopic

The two compounds with structures most like the extended conformation of amphetamine, 2-aminotetralin and 2-aminoindane, were potent anorectics. At dosages which halved the intake of food over 1 h, amphetamine increased motor activity, 2-aminotetralin had no effect, and 2-aminoindane reduced motor activity. 3. Both the anorectic and central stimulant actions of 2-aminoindane were absent in N-ethyl- and N-isopropyl-2-aminoindane. 4. 1-Aminoindane, whose structure is like the folded conformation of amphetamine, produced a small anorectic effect and depressed motor activity.

    Congenital H-type fistula is a rare congenital rectourogenital connection with an external anal opening in a normal or ectopic position. A systematic review was done to study the anatomical types of congenital H-type fistula, embryology, clinical presentation, relative gender distribution, associated anomalies, investigative modalities, and recent advances in treatment of these lesions. A PubMed search included H-type anorectal malformation; H-type anorectal malformations; H-type anorectal; and H-type congenital anorectal that gave 9;43;76;26 abstracts, respectively. Relevant studies and cited articles were studied omitting duplicate search. The reported incidence is 0.1-16 % of all anorectal malformation. The H-type anorectal malformation is 2.5-6 times more common in females and usually associated with a normal anus. In males, the anomaly is usually a variant with an ectopic anus or a perineal fistula. Anatomical types include anovestibular; rectovestibular; rectovaginal fistula in females and rectourethral (bulbar, prostatic, bladder neck) and rectovesical fistula in males. Variants identified include H-type fistula with perineal fistula, perineal groove, H-type sinus, H-type canal, and acquired H-type fistula. This review compiles the available literature over last six decades. Various surgical corrective procedures have been described. The high recurrence decreases with a learning curve and experience.

    Clinically silent gonorrhoea is the major problem in the control of the disease. Only 12 per cent of infected women reported in 1974 because of symptoms, compared with 97 per cent of infected heterosexual men and only 35 per cent of homosexual men with gonococcal proctitis alone. Homosexual men, compared with heterosexual men, had twice as many subsequent sexual contacts after infection and had a higher incidence of early syphilis. Eighty-four per cent had experienced passive anorectal intercourse. Ninety-seven per cent of men with gonococcal urethritis reported because of symptoms, but occasionally (particularly after unsuccessful treatment) urethral gonorrhoea in men may be clinically silent and even require tests of the overnight urethral secretion for diagnosis. For women, and for homosexual men who have had passive anorectal (or oral) intercourse, the indication for attendance for tests for gonorrhoea should be having run the risk, and not the presence of symptoms. Routine tests of the anorectum for gonorrhoea are essential in cases of 80 women at risk, and for most homosexual men since over 80 per cent of these men will have had passive anorectal intercourse. Because gonococcal infections following treatment-failure are often clinically silent in both women and men, symptoms cannot be relied upon to indicate such failure. Follow-up smears and cultures are always essential.

    As fibroblast growth factor 10 (FGF-10) gene expression may have a role in anorectal duct formation, this study aimed to assess the spatiotemporal expression pattern of FGF-10 during development of the rectum and hindgut in human embryos. FGF-10 expression was evaluated in human embryos (n = 85) at 3-8 weeks of gestation after immunohistochemical evaluation using antibodies specific for FGF-10. From weeks 4 to 7 of gestation, FGF-10 expression was observed primarily in the apical epithelium of the dorsal urorectal septum, the cloacal membrane (CM) and the hindgut. Following CM rupture (week 7), the epithelium of the anal canal was negative for FGF-10; however, it was present within the urothelium through week 7. FGF-10 expression during the development of the human hindgut and anorectum suggests that it may play a role in hindgut and anorectal morphogenesis. Copyright © 2013 S. Karger AG, Basel.

    Neurotensin (NT), a tridecapeptide found in the mammalian brain and peripheral tissues, induces a decrease in food intake after central administration. In this investigation, we examine whether the histaminergic system is involved in NT-induced suppression of feeding. Intracerebroventricular injection of NT (0.1-1 nmol/mouse) led to dose-dependent inhibition of food intake in fasted ddY mice. The anorectic effect induced by NT (0.1 nmol/mouse) was ameliorated upon co-administration of pyrilamine (3 nmol/mouse), an antagonist for histomine H1 receptor. The NT-induced anorectic effect was partially ameliorated in H1 knockout mice. The findings suggest that the H1 receptor in part mediates the NT-induced suppression of food intake.

    Endoscopic treatments have emerged as an alternative to surgery, in the treatment of benign colorectal stricture. Unlike endoscopic balloon dilatation, there is limited data on endoscopic electrocautery incision therapy for benign colorectal stricture, especially with regards to safety and long-term patency. We present a case of a 29-year-old female with Crohn's disease who had difficulty in defecation and passing thin stools. A pelvic magnetic resonance imaging scan, gastrograffin enema, and sigmoidoscopy showed a high-grade anorectal stricture. An endoscopic insulated-tip knife incision was successfully performed to resolve the problem. From our experience, we suggest that endoscopic insulated-tip knife treatment may be a feasible and effective modality for patients with short-segment, very rigid, fibrotic anorectal stricture.

    The management of anorectal abscess and anal fistula has changed markedly with time. Invasive methods with high resulting rates of incontinence have given way to sphincter-sparing methods that have a much lower associated morbidity. There has been an increase in reports in the medical literature describing the success rates of the varying methods of dealing with this condition. This article reviews the various methods of treatment and evidence supporting their use and explores advances that may lead to new therapies.

    Purpose: To characterize the prevalence, pathophysiology, and natural history of chronic radiation proctitis 5 years following radiation therapy (RT) for localized carcinoma of the prostate. Methods and Materials: Studies were performed in 34 patients (median age 68 years; range 54-79) previously randomly assigned to either 64 Gy in 32 fractions over 6.4 weeks or 55 Gy in 20 fractions over 4 weeks RT schedule using 2- and later 3-dimensional treatment technique for localized prostate carcinoma. Each patient underwent evaluations of (1) gastrointestinal (GI) symptoms (Modified Late Effects in Normal Tissues Subjective, Objective, Management and Analytic scales including effect on activities of daily living [ADLs]); (2) anorectal motor and sensory function (manometry and graded balloon distension); and (3) anal sphincteric morphology (endoanal ultrasound) before RT, at 1 month, and annually for 5 years after its completion. Results: Total GI symptom scores increased after RT and remained above baseline levels at 5 years and were associated with reductions in (1) basal anal pressures, (2) responses to squeeze and increased intra-abdominal pressure, (3) rectal compliance and (4) rectal volumes of sensory perception. Anal sphincter morphology was unchanged. At 5 years, 44% and 21% of patients reported urgency of defecation and rectal bleeding, respectively, and 48% impairment of ADLs. GI symptom scores and parameters of anorectal function and anal sphincter morphology did not differ between the 2 RT schedules or treatment techniques. Conclusions: Five years after RT for prostate carcinoma, anorectal symptoms continue to have a significant impact on ADLs of almost 50% of patients. These symptoms are associated with anorectal dysfunction independent of the RT schedules or treatment techniques reported here.

    This paper describes the effective result of carbon dioxide laser on type I and II internal hemorrhoids, mixed hemorrhoids, anal fissure or fistula, etc. At present, simple hemorrhoidectomy is less acceptable to patients for its excessive bleeding and severe pain during and after the operation. Therefore, the results of 71 anorectal cases of hemorrhoidectomy using carbon dioxide laser have been observed in our hospital. The rates of effective treatment and cure were 100% and 94.3%, respectively.

    While the association between obesity and urinary incontinence (UI) in women has been clearly documented, the relationship with anal incontinence (AI) is less well defined; moreover, while bariatric surgery has been shown to improve UI, its effect on AI is still unclear. A total of 32 obese women were studied by means of PFDI-20 and PFIQ-7 questionnaires and anorectal manometry before and after bariatric surgery and compared with 71 non-obese women. Obese women showed worse overall questionnaire results (OR 5.18 for PFDI-20 and 2.66 for PFIQ-7). Whereas obese women showed worse results for urinary sub-items and a higher urge UI incidence (43.8 vs 18.3 %, p = 0.013), they did not show worsening in colorecto-anal symptoms. Post-operatively, median PFDI-20 total score did not change (24.2 vs 26.6, p = ns), while there was an improvement in urinary score (14.6 vs 8.3, p < 0.001); median PFIQ-7 improved (4.8 vs 0.0, p = 0.044), but while the urinary score improved (2.4 vs 0.0, p = 0.033), the colorecto-anal score did not change significantly. Although after surgery urge UI decreased from 43.8 to 15.6 % (p = 0.029), the incidence of any AI increased from 28.1 to 40.6 % (p = ns) and flatus incontinence increased from 18.8 to 37.5 % (p = ns). Anorectal manometry did not show significant changes after surgery. Obese women had worse questionnaire results, but while showing a higher incidence of UI, they did not experience anorectal function worsening. After bariatric surgery, there was a slight improvement in PFD symptoms related to UI, but anorectal function did not change significantly and flatus incontinence increased.

    Background Pressure drift (PD), resulting from differences between room and body temperature, reduces the accuracy of pressure measurements with the Manoscan high resolution manometry (HRM) system. Our aims were to assess PD during anorectal HRM. Methods Defined as the residual pressure measured immediately after the catheter was removed, PD was calculated for each sensor and averaged across all 12 sensors in 454 anorectal consecutive studies recorded with 3 HRM catheters. The relationship between PD and study duration, number of prior uses of a catheter, and peak and average pressure exposure during a study were evaluated. The correction of PD with a software algorithm (thermal compensation) was evaluated in 76 studies where the most distal sensor was outside the body. Key Results The PD varied among sensors and across catheters. The average PD (7.3±0.2 mm Hg) was significantly greater for newer catheters, during longer studies, or when sensors were exposed to higher pressures. Together, these factors explained 81% of the variance in overall PD. After thermal compensation, the uncorrected median PD for the most distal sensor was 2.5–5 mm Hg over the study duration. Correcting this changed the interpretation (e.g., as abnormal instead of normal) of at least 1 anorectal parameter in 8 of 76 studies. Conclusions & Inferences During anorectal HRM, PD declines with catheter use and is greater for newer catheters, when sensors are exposed to higher pressures, and for studies of longer duration. While PD is partially corrected with thermal compensation algorithms, the impact on interpretation is modest. PMID:27061208

    Anorectal malformations (ARMs) occur in approximately 1 per 5000 live births. The most commonly used procedure for repair of high ARMs is posterior sagittal anorectoplasty (PSARP). This operation is performed entirely through a perineal approach. The first report of laparoscopically assisted anorectal pull-through (LAARP) for repair of ARMs was presented by Georgeson in 2000. The aim is presenting early experience with laparoscopically assisted anorectal pull-through technique in boys with high anorectal malformations. In the last 5 years 7 boys (9 months to 2 years old) with high ARMs were operated on using the LAARP technique. Laparoscopically the rectal pouch was exposed down to the urethral fistula, which was clipped and divided. Externally, the centre of the muscle complex was identified using an electrical stimulator. In the first 4 patients after a midline incision of 2 cm at the planned anoplasty site, a tunnel to the pelvis was created bluntly and dilated with Hegar probes under laparoscopic control. In the last 3 boys a minimal PSARP was done creating a channel into the pelvis. The separated rectum was pulled down and sutured to the perineum. Laparoscopic mobilization of the rectal pouch and fistula division was possible in all cases. There were no intraoperative complications except one ureteral injury. Patients were discharged home on post-operative day 5 to 7. The early results prove that LAARP, an alternative option to PSARP for treatment of imperforate anus, offers many advantages, including excellent visualization of the pelvic anatomical structures, accurate placement of the bowel into the muscle complex and a minimally invasive abdominal and perineal incision. It allows for shorter hospital stay and faster recovery. However, to compare the functional results against the standard procedure (PSARP), longer follow-up of all patients is necessary.

    Though biofeedback therapy is often effective in patients with fecal evacuation disorder (FED), a common cause of chronic constipation (CC) in tertiary practice, data on anorectal physiological parameters following it are scanty. Consecutive patients with FED with CC diagnosed by abnormalities in at least two of the three tests (anorectal manometry, defecography, and balloon expulsion test [BET]) undergoing biofeedback (two sessions per day, 30 min each, for 2 weeks) during a 3-year period were analyzed. Clinical evaluation, anorectal manometry (ARM), and BET were performed at the beginning and after biofeedback. Incomplete evacuation 42/43 (98%), straining 40/43 (93%), and feeling of outlet obstruction 35/43 (81%) were the most common symptoms among these 43 patients (median age 44 years, range 18-76, 30 [71%] male). All the three tests (defecography, BET, and ARM) were abnormal in 17 (40%) patients and the others had two abnormal tests. Improvement in physiological parameters was noted following biofeedback (median residual anal pressure during defecation 99 mmHg (range 52-148) vs. 78 mmHg (37-182), p = 0.03; maximum intra-rectal pressure 60 mmHg (90-110) vs. 76 mmHg (31-178); p = 0.01; defecation index 1.1 (0.1-23.0) vs. 3.2 (0.5-29.0); p = 0.001). Dyssynergia on ARM and BET got corrected in 22/34 (65%) and 18/30 (60%) patients. At a 1-month follow up, 23/37 (62%) patients reported satisfactory symptomatic improvement. Biofeedback not only improves symptoms but also anorectal physiological parameters in patients with FED.

    AIM: To investigate a new technique of the anorectal fistula treatment with acellular extracellular matrix (AEM). METHODS: Thirty patients with anorectal fistula were treated with AEM. All fistula tracts and primary openings were identified using conventional fistula probe. All tracts were curetted with curet and irrigated with hydrogen peroxide and metronidazole. The AEM was pulled into the fistula tract from secondary to primary opening. The material was secured at the level of the primary opening. The excess AEM was trimmed at skin level at the secondary opening. RESULTS: All of the 30 patients had successful closure of their fistula after a 7-14 d follow-up. The healing rate of anal fistula in treatment group was 100%. The ache time, healing time and anal deformation of treatment group were obviously superior to traditional surgical methods. CONCLUSION: Using AEM anal fistula plug in treatment that causes the anorectal fistula is safe and successful in 100% of patients. It can reduce pain, shorten disease course and protect anal function. PMID:18720541

    The incidence of asymptomatic bacteriuria is reported as 2-14% during pregnancy. Fetal and maternal complications like acute pyelonephritis, hypertension, anemia, preterm labor, low-birth-weight infants and intrauterine growth retardation can be expected. The purpose of this study was to determine the incidence of asymptomatic bacteriuria during pregnancy and its relation to pregnancy complications. The study involved 270 pregnant women up to 32 gestational weeks during a 9-month period. At the initial visit, they were screened with urine culture in order to detect asymptomatic bacteriuria. A control group was formed in a retrospective manner from the first day of the study with 186 pregnant women who delivered in our clinic and who were not screened for asymptomatic bacteriuria. The incidence of asymptomatic bacteriuria was 9.31%. Escherichia coli accounted for 79%, which was the most frequent of the isolates. We observed recurrence and had to apply treatment again to 21.7% of the women. The sensitivity, specificity, positive predictive and negative predictive values of leucocyturia as a screening test for asymptomatic bacteriuria were 91.3%, 83.6%, 45.6% and 98.5%, respectively. We diagnosed preterm labor in six of 23 (26%) with asymptomatic bacteriuria and 16 in 163 (9.3%) women in the urine culture negative group. The ratio acute pyelonephritis in the group which was routinely screened and treated for asymtomatic bacteriuria was 0.5% while the prevalence was 2.1% in the nonscreened group. Considering the relatively high incidence of asymptomatic bacteriuria during pregnancy and the relevant complications, we propose to screen and treat asymptomatic bacteriuria routinely in all pregnant women.

    2012-12-01

    According to the British Association for Sexual Health and HIV guidelines, a full physical examination is recommended in patients with possible late syphilis. The aim of this audit was to review all cases of late syphilis diagnosed at our centre since 1994 to see if a full cardiovascular and neurological examination was documented and also to see what a full examination contributed to the management of asymptomatic patients. Of the 480 medical notes audited, 295 patients were asymptomatic of whom 288 (98%) had normal physical examinations; the rest were either not documented, declined or defaulted follow-up. Seven asymptomatic patients had positive clinical findings but these did not lead to a diagnosis of cardiovascular or neurological syphilis. This audit has shown that performing a physical examination in asymptomatic patients added no benefit in diagnosing complications of late syphilis; it would appear that the physical examination did not alter the management.

    Trichomonas vaginalis is a sexually transmitted anaerobic parasite which causes vaginitis and cervicitis. The present study was carried out to determine the incidence of Trichomonas infection in semen samples of asymptomatic men and also to understand the changes of semen characteristics in the infected individuals before treatment and after treatment with metronidazole (Flagyl, 400 mg x 3x a day for 10 days). The semen obtained from 1131 men was examined for different characteristics and Trichomonas were detected in wet smear preparations in 50 cases (4.42%). The characteristics of semen in them was compared with 52 normal semen samples. Statistical analysis showed that the seminal fluid viscosity and percentage particulate debris was increased significantly in the infected group (P less than 0.001). There was no significant change in the pH of semen. Spermatozoan motility and morphologically normal forms were decreased significantly (P less than 0.001), spermatozoan viability was altered, and there was a significant change in membrane integrity (P less than 0.001) as indicated by the hypoosmotic swelling test. The significant improvement in semen characteristics were seen in 25 cases after a single course of treatment. Therefore, it is possible that in some cases, the infertility seen in asymptomatic individuals may be due to infection by Trichomonas.

The authors report the case of a patient who was operated due to ileus caused by adhesions and a Meckel's diverticulum without any sign of inflammation was accidentally noted and removed. As a surprise, the pathological examination of the diverticulum proved carcinoid tumor, a neuroendocrine malignant tumor. The case raises the importance of the removal of asymptomatic Meckel's diverticulum.

    The aim of this study was to identify highly oncogenic forms of human papillomavirus in the oral mucosa of asymptomatic men. In this study, we analyzed samples of exfoliated cells from the oral cavity of 559 asymptomatic men. DNA-human papillomavirus was detected using the consensus primers PGMY09/11; viral genotyping was performed using type-specific PCR and restriction fragment length polymorphism. DNA-human papillomavirus was detected in 1.3% of the study participants and of those 42.8% were infected by more than one type of virus. Viral types included HPV6, 11, 89 (low oncogenic risk), and HPV52, 53 (high oncogenic risk). Increased vulnerability to human papillomavirus infection was observed in individuals aged over 26 years, among those who reported oral sex practices, and in those who have had more than 16 sexual partners since first engaging in sexual intercourse. There was a low prevalence of human papillomavirus detection in the oral mucosa of asymptomatic men. Highly oncogenic human papillomavirus types and infection by more than one viral type was observed. Oral sex practices and a large number of sexual partners may increase the risk of acquiring human papillomavirus infection. Copyright © 2014. Published by Elsevier Editora Ltda.

    The terminology for anorectal dysfunction in women has long been in need of a specific clinically-based Consensus Report. This Report combines the input of members of the Standardization and Terminology Committees of two International Organizations, the International Urogynecological Association (IUGA) and the International Continence Society (ICS), assisted on Committee by experts in their fields to form a Joint IUGA/ICS Working Group on Female Anorectal Terminology. Appropriate core clinical categories and sub classifications were developed to give an alphanumeric coding to each definition. An extensive process of twenty rounds of internal and external review was developed to exhaustively examine each definition, with decision-making by collective opinion (consensus). A Terminology Report for anorectal dysfunction, encompassing over 130 separate definitions, has been developed. It is clinically based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different specialty groups involved in female pelvic floor dysfunction. Female-specific anorectal investigations and imaging (ultrasound, radiology and MRI) has been included whilst appropriate figures have been included to supplement and help clarify the text. Interval review (5-10 years) is anticipated to keep the document updated and as widely acceptable as possible. A consensus-based Terminology Report for female anorectal dysfunction terminology has been produced aimed at being a significant aid to clinical practice and a stimulus for research.

  3. Central expression and anorectic effect of brain-derived neurotrophic factor are regulated by circulating estradiol levels.

    Estrogens potently suppress food intake. Compelling evidence suggests that estradiol, the primary form of estrogens, reduces food intake by facilitating other anorectic signals. Brain-derived neurotrophic factor (BDNF), like estradiol, appears to suppress food intake by affecting meal size. We hypothesized that estradiol modulates Bdnf expression and the anorectic effect of BDNF. The first goal was to determine whether Bdnf expression was regulated by endogenous estradiol of cycling rats and by cyclic estradiol treatment using ovariectomized rats. Bdnf expression within the ventromedial nucleus of hypothalamus (VMH) was temporally elevated at estrus following the estradiol peak, which coincided with the decline in feeding at this phase of the ovarian cycle. Additionally, food intake and body weight were increased following ovariectomy with a parallel decrease in Bdnf expression in the VMH. All of these alterations were reversed by cyclic estradiol treatment, suggesting that Bdnf expression within the VMH was regulated in an estradiol-dependent manner. The second goal was to determine whether estradiol modulates the anorectic effect of BDNF. Sham-operated estrous rats and ovariectomized rats cyclically treated with estradiol responded to a lower dose of central administration of BDNF to decrease food intake than male rats and oil-treated ovariectomized rats, implying that endogenous estradiol or cyclic estradiol replacement increased the sensitivity to anorectic effect of BDNF. These data indicate that Bdnf expression within the VMH and the anorectic effect of BDNF varied depending on plasma estradiol levels, suggesting that estradiol may regulate BDNF signaling to regulate feeding.

    Cytological screening for anal cancer precursors is not always possible. We investigated digital ano-rectal examination (DARE) as a means of early anal cancer detection in HIV-positive men who have sex with men (MSM). We recruited 327 HIV-positive MSM aged 35 and over from clinics with HIV physicians in Melbourne, Australia, to receive an annual DARE. We analyzed baseline data from patient questionnaires regarding general, anal and sexual health, adverse effects from the anal examination, cancer worry, and quality of life. The majority of men (82%, 95% CI:78-87) felt relaxed during the DARE, 1% (95% CI:0-3) complained of pain, and 1% (95% CI:0-4) reported bleeding after the examination. Nearly all men (99%, 95% CI:96-100) were willing to continue with an annual DARE. Quality of life was unaffected with utility scores of 0.76 before examination vs. 0.77 two weeks after examination, (p = 0.41). An anal abnormality was detected in 86 men (27%, 95% CI:22-31), with one anal cancer identified. The specialist referral rate following DARE was 5% (95% CI:3-8). Recruitment rates were significantly associated with the clinic setting (sexual health centre 78%, general practice 13%, hospital 14%, p = 0.002) and specialty (sexual health physician 67%, general practitioner 20%, infectious disease physician 14%, p = 0.031). Annual DARE to detect anal cancer in HIV-positive MSM was acceptable for patients, with minimal side effects. Strategies to increase HIV physician's patient recruitment would be needed if DARE were to be implemented in anal cancer screening. © The Author(s) 2015.

    We report an alleged case of sexual assault in which an anti-wrinkle cream could have been used as a lubricant. Three anorectal samples taken from the victim were given to us in an attempt to document the presence of remains of the cream involved. After examining the composition of the cream, octocrylene (OCT) was selected as the most relevant marker for this analysis. An ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed for identification of OCT. Anorectal samples were diluted with methanol and injected onto an Acquity BEH C18 column using a gradient mode with 0.1% formic acid/acetonitrile as the mobile phase. Data were acquired using positive electrospray ionization and multiple reaction monitoring. Three transitions were selected for OCT (m/z 362.2>250.0, m/z 362.2>232.0 and m/z 362.2>204.0). The analysis of the cream seized at the offender's home confirmed the presence of OCT as an ingredient, and the analysis of extracts from the anorectal samples also allowed the formal identification of OCT. These results strongly suggest that a cosmetic containing octocrylene as an ingredient has in fact been applied to the anus of the alleged victim. Copyright © 2011 Elsevier Ireland Ltd.

    Although microembolus monitoring has been widely used for ischemic cerebrovascular disease, the clinical significance of microembolic signal (MES) in asymptomatic middle cerebral artery (MCA) stenosis remains unclear. We aim to investigate the frequency of MES and the value of MES in predicting ischemic stroke secondary to asymptomatic MCA stenosis. From June 2011 to December 2012, microembolus monitoring was performed in 83 asymptomatic and 126 symptomatic subjects. By comparing the demographics and risk factors between the symptomatic and asymptomatic subjects, we found that the ratio of male sexuality and smoking history differed (101/126 vs 43/83, and 88/126 vs 38/83, respectively, p<0.01). The frequency of MES was significantly higher in the symptomatic group than in the asymptomatic group (49/126 vs 2/108, p<0.01). Specifically, the frequency of MES in the symptomatic and asymptomatic groups with mild stenosis, moderate stenosis, severe stenosis and occlusion groups was 4/18 (22.22%) vs 0/30 (0), 13/31 (41.94%) vs 1/28 (3.57%), 30/62 (48.39%) vs 1/39 (2.56%), 2/15 (13.33%) vs 0/11 (0), respectively. Except for the occlusive group, the frequency of MES is correlated with stenosis degree and symptom. Two patients in the asymptomatic group were found positive for MES, and the MES number was 1 for both. During the one-year follow-up, neither of them developed ischemic stroke. In conclusion, MES detected with TCD differs between symptomatic and asymptomatic MCA stenoses. Due to the low frequency, the value of MES as a predictor of subsequent ischemic stroke in patients with asymptomatic MCA stenosis might be limited. PMID:24551204

    Although surgical residents are expected to be proficient in the diagnosis and management of anorectal pathology upon graduation, there is little data related to the timing and degree of proficiency acquired during training. Prospective study of new patients presenting to a colorectal surgical clinic for evaluation of anorectal complaints over a 3-y period. Trainees performed an initial evaluation and recorded their exam findings, diagnosis, and treatment plan. A separate evaluation by a staff colorectal surgeon was performed, with results compared by an independent reviewer. A total of 236 patient evaluations were included. The accuracy of referral diagnosis was significantly better when originated from a surgeon than from all other referral sources (91.7% versus 59.1%, P = 0.031). The most common conditions were internal hemorrhoids (25%), anal fissures (22%), and external hemorrhoids (19.5%). Internal hemorrhoids were most commonly misdiagnosed as external hemorrhoids (58%). Anal fissures were missed 38% of the time, and were most often given the diagnosis of internal hemorrhoids (45%). Residents also demonstrated difficulty in identifying thrombosis in external hemorrhoids, with a 45% error rate. Medical students and residents had an overall correct primary diagnosis of 69.5%; however, there was a significant improvement in the accuracy of diagnosis from medical students and interns to upper level residents (62.9% versus 81.2%, P = 0.003). Medical treatment plans agreed between resident and staff in 74%, the surgical management agreed in 62%, and overall the residents had the correct diagnosis and corresponding treatment plan in 44%. Additional adjunctive procedures were proposed in 66 patients with residents stating the correct adjunct in 79%. The most frequently missed adjuncts were endorectal ultrasound (34%) and colonoscopy (28%). Surgical trainees demonstrated significant deficiencies in the ability to evaluate and manage anorectal pathology; however

    The aim of this study was to investigate the effects of spinal anesthesia using two different doses of fentanyl combined with low-dose levobupivacaine in anorectal surgery. In this prospective, double-blind study, 52 American Society of Anaesthesiologists I-II patients scheduled for elective anorectal surgery were randomized into two groups. The patients in group I received intrathecal 2.5mg hyperbaric levobupivacaine plus 12.5μg fentanyl and in group II received intrathecal 2.5mg hyperbaric levobupivacaine plus 25μg fentanyl. All the patients remained in the seated position for 5min after completion of the spinal anesthesia. Sensory block was evaluated with pin-prick test and motor block was evaluated with a modified Bromage scale. Motor block was not observed in both of the groups. The sensory block was limited to the S2 level in group I, and S1 level in group II. None of the patients required additional analgesics during the operation. Time to two-segment regression was shorter in group I compared with group II (p<0.01). One patient in group I and 5 patients in group II had pruritus. Hemodynamic parameters were stable during the operation in both of the groups. Spinal saddle block using hyperbaric levobupivacaine with both 12.5μg and 25μg fentanyl provided good quality of anesthesia without motor block for anorectal surgery in the prone position.

    Background & Aims High-definition anorectal manometry (HDAM-3D) provides a topographic and 3-dimensional profile of anorectal pressure. We assessed anorectal sensori-motor function in healthy adults, the reproducibility of measurements made with HDAM-3D, and the accuracy of data analysis by its software. Methods Anal sphincter pressures and rectal sensory thresholds were measured in 78 healthy subjects via placement of a 10 mm rigid probe, with 256 circumferentially arrayed pressure sensors, and a balloon in the rectum. The bearing down maneuver was assessed in a subset of 18 subjects. We compared data analyzed by experts with findings from automated software analysis. Measurements made in a subset of 16 subjects, 2 weeks apart, were compared to determine reproducibility. Results Resting, squeezing, and sustained squeezing pressures were significantly higher in men than women (P<.05); other parameters were similar. Desire and urgency to defecate were similar between men and women, but the maximal tolerable volume was significantly lower in women (P<.05). Older women (>50 y) had significantly lower resting (P<.01) and sustained squeeze pressures (P<.04). Dyssynergic patterns of defecation were observed in 12/18 subjects (67%) who attempted to defecate without the 60 cc rectal balloon distension and in 6/18 subjects (33%) with the 60 cc rectal balloon distension. Rest–retest values correlated, (r = 0.81) as did conclusions made by experts vs software analyses of data (r = 0.99). Conclusions Based on HDAM-3D measurements in healthy adults, anal sphincter pressures are higher in men than women, but sensory and other parameters are similar; older subjects have weaker sphincters. Many people were found to have dyssynergic patterns of defecation, which could be related to the probe or other technical issues, so this technique may not be suitable for assessing defecation patterns. Measurements made by HDAM-3D are reproducible and data can be accurately analyzed by its

    Rectal intussusception and external rectal prolapse are uncommon proctographic findings in men reflecting the lack of studies investigating such patients. The aim of this study was to identify the demographic, clinical, and physiological characteristics of this population with a view to appreciate the mechanism of development of this condition. All men, presenting with symptoms of constipation or fecal incontinence, who were diagnosed proctographically with recto-rectal intussusception (RRI)/recto-anal intussusception (RAI) or external rectal prolapse (ERP) between 1994 and 2007 at a tertiary academic colorectal unit were studied. Demographics, relevant comorbidities, distribution and symptom duration, and anorectal physiology results were analyzed retrospectively for each proctographic group and intergroup comparisons performed. Two hundred five men (median age 50 y; range, 13-86) including 155 (75.6%) without any relevant comorbidities were studied. A significant proportion of patients in all proctographic groups reported rectal evacuatory difficulty ([RRI, 46.4%], [RAI, 39.4%], [ERP, 44.8%]; P = 0.38,analysis of variance). Patients also reported a combination of fecal incontinence symptoms (e.g., urge, passive, postdefecatory leakage) that did not differ across the proctographic groups. Anorectal physiological parameters were within normal range and were not found to be statistically different between the proctographic groups with the exception of anal resting pressure, which was lowest in ERP patients (62 cm H2O; range, 14-155) compared with patients with RRI (89 cm H2O; range, 16-250; P = 0.003) and RAI (92 cm H2O; range, 38-175; P = 0.006). Men with rectal intussusception and prolapse present with a combination of symptoms, predominantly defective rectal evacuation. Anorectal physiological assessment has failed to shed light into the mechanism of development of this condition and thus, the need for large observational studies incorporating integrated

    To determine whether anorectal biofeedback therapy can improve the symptoms of fecal incontinence (FI) in patients with scleroderma when compared to patients with functional FI, and also whether there is any effect on anorectal physiology or quality of life (QOL). FI in patients with scleroderma is highly prevalent and is associated with significant loss of QOL. Biofeedback has been proven to be an effective treatment for functional FI, but there are no data to support its use in scleroderma. 13 consecutive female patients (median age 59, IQR 47-65 years) with scleroderma, and 26 age- and parity-matched female patients with functional FI (disease controls, 2:1), underwent biofeedback therapy for management of FI. Fecal incontinence severity index (FISI), anorectal physiology, feeling of control and QOL were collected before and after 6 weeks of biofeedback therapy, with additional scoring repeated at 6-month follow-up. After biofeedback treatment FISI, feeling of control and QOL significantly improved in both groups (p < 0.005). There was no difference in the degree in improvement in physiology, FISI or QOL between scleroderma patients and functional FI patients. Long-term improvement in FISI and control were seen in both groups and for QOL only in the scleroderma cohort (p < 0.05). Patients with scleroderma benefit from biofeedback therapy to the same extent as that achieved in patients with functional FI. There are significant improvements in symptoms, physiology and QOL. Biofeedback is an effective, low-risk treatment option in this patient group.

    Electrogalvanic stimulation and biofeedback therapy for the treatment of intractable anorectal pain have been reported. However, these therapeutic modalities have some disadvantages and insufficient effectiveness. We noticed that digital examination revealed the strongly tender point in both lateral sides of the rectum and introduced linearly polarized near-infrared irradiation therapy to the strongly tender point. The purpose of this study was to review the outcomes and estimate its usefulness. A total of 35 consecutive patients complained of vague and deep pain in the anorectum. Fourteen patients had a history of lower abdominal surgery. Eighteen patients had disordered defecation. The linearly polarized near-infrared light was irradiated to the strongly tender point on or a few centimeters apart from the skin for ten minutes. The effect of the therapy was assessed as excellent, good, no change, or worse by the patients themselves. Ten patients had the strongly tender point in the left side, 8 in the right posterior, and 17 in both. Five patients estimated as excellent, 28 as good, and 2 as no change. Mean total number of irradiation was 18.8 (range, 1-235), and mean number of irradiation for relief from pain was 2.5 (range, 1-9). Anorectal pain recurred in four patients, who received the same therapy and improved. Four patients felt hot during the irradiation, and a patient had frequent micturition after the irradiation. These mild complications easily disappeared. The linearly polarized near-infrared irradiation therapy is a simple, safe, and effective modality for relief from intractable anorectal pain and recommended for primary therapy.

    More than 800 patients suffering from primary gout or asymptomatic hyperuricemia were examined for the values of total cholesterol and triglycerides and the pattern of lipoproteins. The values for HDL (high-density-lipoprotein = alpha-lipoprotein), LDL (low-density-lipoprotein = beta-lipoprotein) and VLDL (very-low-density-lipoprotein = pre-beta-lipoprotein), found in lipid electrophoresis, were significant abnormal as well in the group of patients with gout (n = 147) as in the group of patients with asymptomatic hyperuricemia (n = 700) versus the healthy controls. It was remarkable, that the values of lipoproteins in asymptomatic hyperuricemia almost were abnormal just as often as in primary gout. Approximately 80% of both groups showed an increased LDL, around 35% a decreased HDL, and an increased VLDL was found in 72% of patients with gout and in 54% of asymptomatic hyperuricemia. Pathological changes of all lipoproteins (HDL, LDL and VLDL) appeared in 23% of patients with gout and in 20% of patients with asymptomatic hyperuricemia. Only 2.7% of patients with gout and 4.8% with hyperuricemia showed a normal lipometabolism.

    Up to 30% of mothers develop acute pyelonephritis if asymptomatic bacteriuria is untreated. Asymptomatic bacteriuria may have a role in preterm birth, or it may be a marker for low socioeconomic status and thus, low birth weight. The objective of this review was to assess the effect of antibiotic treatment for asymptomatic bacteriuria on persistent bacteriuria during pregnancy, the risk of preterm delivery and the development of pyelonephritis after delivery. I searched the Cochrane Pregnancy and Childbirth Group trials register. Randomised trials comparing antibiotic treatment with placebo or no treatment in pregnant women with asymptomatic bacteriuria found on antenatal screening. Trial quality was assessed. Thirteen studies were included. Overall the study quality was not strong. Antibiotic treatment compared to placebo or no treatment was effective in clearing asymptomatic bacteriuria (odds ratio 0.07, 95% confidence interval 0.05 to 0.10). The incidence of pyelonephritis was reduced (odds ratio 0.25, 95% confidence interval 0.19 to 0.32). Antibiotic treatment was also associated with a reduction in the incidence of preterm delivery or low birth weight babies (odds ratio 0.60, 95% confidence interval 0.45 to 0.80). Antibiotic treatment appears to be effective in reducing the risk of pyelonephritis in pregnancy. An apparent reduction in preterm delivery is consistent with current theories about the role of infection in preterm birth, but this association should be interpreted with caution.

    Asymptomatic bacteriuria occurs in 2% to 10% of pregnancies and, if not treated, up to 30% of mothers will develop acute pyelonephritis. Asymptomatic bacteriuria has been associated with low birthweight and preterm delivery. To assess the effect of antibiotic treatment for asymptomatic bacteriuria on persistent bacteriuria during pregnancy, the development of pyelonephritis and the risk of low birthweight and preterm delivery. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (January 2007). Randomized trials comparing antibiotic treatment with placebo or no treatment in pregnant women with asymptomatic bacteriuria found on antenatal screening. We assessed trial quality. Fourteen studies were included. Overall the study quality was poor. Antibiotic treatment compared to placebo or no treatment was effective in clearing asymptomatic bacteriuria (risk ratio (RR) 0.25, 95% confidence interval (CI) 0.14 to 0.48). The incidence of pyelonephritis was reduced (RR 0.23, 95% CI 0.13 to 0.41). Antibiotic treatment was also associated with a reduction in the incidence of low birthweight babies (RR 0.66, 95% CI 0.49 to 0.89) but a difference in preterm delivery was not seen. Antibiotic treatment is effective in reducing the risk of pyelonephritis in pregnancy. A reduction in low birthweight is consistent with current theories about the role of infection in adverse pregnancy outcomes, but this association should be interpreted with caution given the poor quality of the included studies.

  18. Leptin extends the anorectic effects of chronic PYY(3-36) administration in ad libitum-fed rats.

    Acute administration of peptide YY(3-36) [PYY(3-36)] results in a reduction in food intake in several different vertebrates. However, long-term continuous administration of PYY(3-36) causes only a transient reduction in food intake, thus potentially limiting its therapeutic efficacy. We hypothesized that a fall in leptin levels associated with reduced food intake could contribute to the transient anorectic effects of continuous PYY(3-36) infusion and thus that leptin replacement might prolong the anorectic effects of PYY(3-36). Seven-day administration of 100 microg x kg body wt(-1) x day(-1) PYY(3-36) using osmotic minipumps caused a significant reduction in food intake of ad libitum-fed rats, but only for the first 2 days postimplantation. Circulating levels of leptin were reduced 1 day following continuous infusion of PYY(3-36), and combined leptin infusion at a dose of leptin that had no anorectic effects on its own (100 microg x kg body wt(-1) x day(-1)) prolonged the anorectic actions of PYY(3-36) in ad libitum-fed rats for up to 6 days postimplantation and yielded reduced weight gain compared with either peptide alone. The inhibitory effects of 100 microg x kg body wt(-1) x day(-1) PYY(3-36) on food intake were absent in rats refed after a 24-h fast and substantially reduced at a dose of 1,000 microg x kg body wt(-1) x day(-1) PYY(3-36). Leptin replacement was unable to recover the anorectic effects of PYY(3-36) in fasted rats. Our results suggest that an acute fall in leptin levels is not solely responsible for limiting duration of action of chronic PYY(3-36) infusion, yet chronic coadministration of a subanorectic dose of leptin can extend the anorectic effects of PYY(3-36).

    Purpose: To evaluate and compare the effect of argon plasma coagulation (APC) and topical formalin for intractable rectal bleeding and anorectal dysfunction associated with chronic radiation proctitis. Methods and Materials: Thirty men (median age, 72 years; range, 49-87 years) with intractable rectal bleeding (defined as ≥1× per week and/or requiring blood transfusions) after radiation therapy for prostate carcinoma were randomized to treatment with APC (n=17) or topical formalin (n=13). Each patient underwent evaluations of (1) anorectal symptoms (validated questionnaires, including modified Late Effects in Normal Tissues–Subjective, Objective, Management, and Analytic and visual analogue scales for rectal bleeding); (2) anorectal motor and sensory function (manometry and graded rectal balloon distension); and (3) anal sphincteric morphology (endoanal ultrasound) before and after the treatment endpoint (defined as reduction in rectal bleeding to 1× per month or better, reduction in visual analogue scales to ≤25 mm, and no longer needing blood transfusions). Results: The treatment endpoint was achieved in 94% of the APC group and 100% of the topical formalin group after a median (range) of 2 (1-5) sessions of either treatment. After a follow-up duration of 111 (29-170) months, only 1 patient in each group needed further treatment. Reductions in rectal compliance and volumes of sensory perception occurred after APC, but no effect on anorectal symptoms other than rectal bleeding was observed. There were no differences between APC and topical formalin for anorectal symptoms and function, nor for anal sphincteric morphology. Conclusions: Argon plasma coagulation and topical formalin had comparable efficacy in the durable control of rectal bleeding associated with chronic radiation proctitis but had no beneficial effect on anorectal dysfunction.

    Background Inter-observer variability limits the reproducibility of pelvic floor motion measured by magnetic resonance imaging (MRI). Our aim was to develop a semi-automated program measuring pelvic floor motion in a reproducible and refined manner. Methods Pelvic floor anatomy and motion during voluntary contraction (squeeze) and rectal evacuation were assessed by MRI in 64 women with fecal incontinence (FI) and 64 age-matched controls. A radiologist measured anorectal angles and anorectal junction motion. A semi-automated program did the same and also dissected anorectal motion into perpendicular vectors representing the puborectalis and other pelvic floor muscles, assessed the pubococcygeal angle, and evaluated pelvic rotation. Key Results Manual and semi-automated measurements of anorectal junction motion (r = 0.70; p < 0.0001) during squeeze and evacuation were correlated, as were anorectal angles at rest, squeeze, and evacuation; angle change during squeeze or evacuation were less so. Semi-automated measurements of anorectal and pelvic bony motion were also reproducible within subjects. During squeeze, puborectalis injury was associated (p ≤ 0.01) with smaller puborectalis but not pelvic floor motion vectors, reflecting impaired puborectalis function. The pubococcygeal angle, reflecting posterior pelvic floor motion, was smaller during squeeze and larger during evacuation. However, pubococcygeal angles and pelvic rotation during squeeze and evacuation did not differ significantly between FI and controls. Conclusion & Inferences This semi-automated program provides a reproducible, efficient and refined analysis of pelvic floor motion by MRI. Puborectalis injury is independently associated with impaired motion of puborectalis, not other pelvic floor muscles in controls and women with FI. PMID:22765510

    Abstract Often when calcite is found as a component of urinary calculi, they are considered false calculi or artifacts. We present a case of true calcite urolithiasis. The stone material was removed percutaneously from a severely malnourished anorectic woman and analyzed by infrared spectroscopy (IRS). In addition, calcite urolithiasis was confirmed in several recurrent stone events by IRS. Laxative abuse with magnesium oxide was believed to be the underlying cause of stone formation, and ammonium chloride given as one weekly dose turned out to be effective for stone prevention.

    The material set out in this text has been designed to show the wide range of procedures which have the capacity to modify eating behavior--to produce hyper- or hypophagia, to alter the profile of eating patterns, or to adjust dietary preferences and selection. Accordingly, in investigating anorectic drugs it seems necessary to observe the effects of drug actions in a variety of experimental models. This strategy will provide a more complete description of the effect of a drug, will throw light on the mechanism of action, and will provide a more realistic base for predicting the effects of drugs in man.

    Asymptomatic bacteriuria, the presence of bacteria in urine without symptoms of acute urinary tract infection, predisposes pregnant women to the development of urinary tract infections and pyelonephritis, with an attendant pregnancy related complications. To measure the prevalence of asymptomatic bacteriuria among ante-natal clients at the Korle-Bu Teaching Hospital in Ghana and its' associated risk factors. A cross-sectional study involving 274 antenatal clients was conducted over a period of 4 weeks. A face to face questionnaire was completed and midstream urine collected for culture and antimicrobial susceptibility testing. The prevalence of asymptomatic bacteriuria was 5.5%. It was associated with sexual activity during pregnancy (Fisher's Exact 5.871, p-value 0.0135), but not with sexual frequency. There were no significant associations with educational status, parity, gestational age, marital status and the number of foetuses carried. The commonest organism isolated was Enterococcus spp (26.7%) although the enterobacteriaceae formed the majority of isolated organisms (46.7%). Nitrofurantoin was the antibiotic with the highest sensitivity to all the isolated organisms. The prevalence of asymptomatic bacteriuria among ante-natal clients at this large teaching hospital in Ghana is 5.5%, which is lower than what has been found in other African settings. Enterococcus spp was the commonest causative organism. However, due to the complications associated with asymptomatic bacteriuria, a policy to screen and treat- all pregnant women attending the hospital, is worth considering.

    The aim of this study was to examine the effects of a serotonergic anorectic agent, dexnorfenfluramine (DNOR), on food intake in mice whose meals were constrained to specified periods each day and by effort. Mice were forced to adopt a human-like pattern of regular meals by making food available for four periods of 40 min/24-h period, mostly at night. They lived in behavior test chambers with a closed economy for food and were required to emit a fixed unit price (FUP) of either 2 or 25 nose pokes (FUP2, FUP25) to receive a 20 mg pellet of food. Once responding and intake were stable, mice were injected with a vehicle or DNOR (3 or 6 mg/kg) 1 h before a specified feeding opportunity. Food intake was dose-dependently suppressed at the next meal and to a greater extent when the cost of food was high (FUP25). Within a meal, the effect of the drug was the greatest in the first half of the available time. Therefore, the anorectic effect of DNOR was modified by the concurrent cost of food.

    We report a case of locally recurrent anorectal cancer treated with proton beam therapy (PBT) alone that led to a clinically complete response. A 70-year-old woman with paraparesis due to infantile paralysis underwent abdominoperineal resection (APR) and D3 lymphadenectomy for anorectal cancer (PERb, type 2, 50×40 mm, muc-tub1, M1a[lung], Stage IV a]. Three months after APR, right middle and right lower lobectomies were performed for synchronous lung metastases. Adjuvant chemotherapy was not administered. One year and 8 months after APR, computed tomography (CT) showed local recurrence of the tumor (29×28 mm), which contacted the right ischial spine. Pelvic exenteration combined with sacral resection was not performed because of the patient's poor performance status. PBT (70 Gy [RBE]/25 F/5 week) was administered for treatment of the recurred tumor. CT revealed that the tumor disappeared 1 year after PBT, which was defined as complete response. The patient is alive and has not experienced recurrence for 7 years.

    We assessed eating attitudes and body image using the Eating Attitudes Test-26 (EAT: Garner & Garfinkel, 1979) and a 17-item body image scale in Israeli Jewish female high school populations in five distinct residential settings (kibbutz, moshav, city, and 2 different boarding schools); in five ethnically distinct Arab female high school populations (Muslim, Christian, Druze, Circassian, and Bedouin); and in a group of hospitalized adolescent girls with anorexia nervosa. We hypothesized that the attitudes of the adolescent females most exposed to Western body shape ideals and simultaneously undergoing role conflict between traditional and modern images of the female role would most resemble attitudes of anorectics. This was partly supported by the findings. Ethnic differences also emerged in attitude toward food. All the Arab populations except the Circassian showed strong Western influences in their attitudes toward eating and body image and thus may well be prone to epidemics of anorexia and similar eating disorders in the near future. Kibbutz girls were most similar to the anorectic group.

  12. Dkk1 in the peri-cloaca mesenchyme regulates formation of anorectal and genitourinary tracts.

    2014-01-01

    Anorectal malformation (ARM) is a common birth defect but the developmental history and the underlying molecular mechanism are poorly understood. Using murine genetic models, we report here that a signaling molecule Dickkopf-1 (Dkk1) is a critical regulator. The anorectal and genitourinary tracts are major derivatives of caudal hindgut, or the cloaca.Dkk1 is highly expressed in the dorsal peri-cloacal mesenchymal (dPCM) progenitors. We show that the deletion of Dkk1 causes the imperforate anus with rectourinary fistula. Mutant genital tubercles exhibit a preputial hypospadias phenotype and premature urethral canalization.Dkk1 mutants have an ectopic expansion of the dPCM tissue, which correlates with an aberrant increase of cell proliferation and survival. This ectopic tissue is detectable before the earliest sign of the anus formation, suggesting that it is most likely the primary or early cause of the defect. Deletion of Dkk1 results in an elevation of the Wnt/ß-catenin activity. Signaling molecules Shh, Fgf8 and Bmp4 are also upregulated. Furthermore, genetic hyperactivation of Wnt/ß-catenin signal pathway in the cloacal mesenchyme partially recapitulates Dkk1 mutant phenotypes. Together, these findings underscore the importance ofDKK1 in regulating behavior of dPCM progenitors, and suggest that formation of anus and urethral depends on Dkk1-mediated dynamic inhibition of the canonical Wnt/ß-catenin signal pathway.

    2016-10-01

    Introduction We describe a two-port laparoscopic technique to create a colostomy in the descending colon with separated stomas for newborns with anorectal malformations. Material and Methods Six patients with an anorectal malformation underwent this procedure in the early-neonatal period. The surgical technique was performed with two ports, which allows for an accurate inspection of the abdominal contents. The first loop of the sigmoid colon is grasped through the first port and exteriorized while the attachments to the left retroperitoneum and direction of the loop are checked with the scope introduced in the second port. The division of the colon is performed extracorporally, the colon irrigated of meconium, and the distal colon moved to the second port incision. Both stomas are then fixed to the abdominal wall. Results The time of the procedure ranged from 50 to 90 minutes. A Mullerian duplication was noted in one case. Oral intake was started during the first 12 to 24 hours. No complications were seen during or after the procedure. Conclusions This technique allows for the precise localization of the colostomy with direct visualization, provides for the inspection of the internal genitalia, eliminates the incision between the two stomas and its complications, allows for painless stoma bag changes immediately after surgery, avoids twisting of the colostomy, and permits a cosmetically pleasing incision at the colostomy closure.

    Of clinics responding to the audit, 99 and 97% have policies that are compliant with the British Association for Sexual Health and HIV National Guidelines for testing of asymptomatic men and women for HIV and syphilis, respectively. All clinics offer men, and all but one clinic offer women, screening for chlamydial infection with nucleic acid amplification tests (NAATs), as recommended by the guidelines. However, for gonorrhoea screening one-third of clinics offer men urine or urethral NAATs, and one quarter of clinics offer women endocervical, vulvovaginal or urinary NAATs, and not endocervical culture, and these practices are not compliant with the guidelines. Eight clinics did not specify whether they routinely offer testing for gonorrhoea in women. One-third of clinics routinely perform rectal and oropharyngeal screening for gonorrhoea in men who have sex with men (MSM), but fewer screen for chlamydia, regardless of sexual history which is stated as a determinant of offering screening at these anatomical sites. Finally, one-fifth of clinics offer urethral microscopy to asymptomatic heterosexual men and MSM, and about one half of clinics offer urethral culture for detection of gonorrhoea in asymptomatic women, even though these practices are not compliant with the guidelines.

  17. An anthropologically based model of the impact of asymptomatic cases on the spread of Neisseria gonorrhoeae

    2015-01-01

    Neisseria gonorrhoeae (GC) remains a serious burden in many high-sexual-activity, undertreated populations. Using empirical data from a 2009 study of GC burden among pastoralists in Kaokoveld, Namibia, we expand the standard gonorrhoea transmission model by using locally derived sexual contact data to explore transmission dynamics in a population with high rates of partner exchange and low treatment-seeking behaviour. We use the model to generate ball-park estimates for transmission probabilities and other parameter values for low-level (i.e. less than approx. 1200 copies/20 µl PCR reaction) asymptomatic infections, which account for 74% of all GC infections found in Kaokoveld in 2009, and to describe the impact of asymptomatic, low-level infections on overall prevalence patterns. Our results suggest that GC transmission probabilities are higher than previously estimated, that untreated infections take longer to clear than previously estimated and that a high prevalence of low-level infections is partially due to larger numbers of untreated, asymptomatic infections. These results provide new insights into the natural history of GC and the challenge of syndromic management programmes for the eradication of endemic gonorrhoea. PMID:25808340

    There are no evidence-based guidelines for the specific management of rectal Chlamydia trachomatis (CT) infection. All men who have sex with men (MSM) diagnosed with asymptomatic rectal CT by nucleic acid amplification test (NAAT) at a large London genitourinary (GU) medicine clinic between September 2006 and September 2009 were offered oral doxycycline 100 mg twice daily for seven days and invited for a test of cure (TOC) by CT NAAT four weeks after treatment. A total of 487 asymptomatic rectal CT infections were diagnosed and analysis was restricted to 165 TOCs from men whose only treatment had been doxycycline for seven days. The median time post-treatment for TOC was 45 days (interquartile range [IQR], 34-88). Only two patients tested CT-positive at follow-up. One had taken doxycycline only for three days; the other attended for TOC 240 days after the completion of doxycycline treatment and at this time presented with new symptoms in the context of ongoing high sexual risk. Our findings show that doxycycline 100 mg twice daily for seven days is highly effective treatment for asymptomatic rectal CT infection, achieving clearance of CT in 98.8% (163/165; 95% CI 95.4-99.9%) of cases. We advocate doxycycline for seven days as first-line therapy for asymptomatic rectal CT.

    This retrospective study was planned for a good risk assessment of asymptomatic patients affected by ventricular pre-excitation. From 1985 to 2007, 124 patients with an atrioventricular pathway (electrocardiographic signs of ventricular pre-excitation) were admitted to our cardiology division. The average age was 7 years (range 1 month to 18 years). The mean follow-up period in the whole population of patients was 4.2 years (range 1-13 years). Four patients were lost during the follow-up. During this period, all patients remained in good health. In all of them, we performed a Holter evaluation every year. An intermittent pathway was detected in 18 patients (15%), and four of them (3.4%) showed a supraventricular tachycardia even though they were asymptomatic patients. An ergometric test was performed in 76 asymptomatic patients; 16 children (21%) showed a total abrupt vanishing of delta wave. A transoesophageal electrophysiological evaluation was performed in 14 patients. According to our data, asymptomatic Wolff-Parkinson-White syndrome in children has a good outcome during a short-term (4 years) follow-up. The usefulness of electrophysiological evaluation (in particular its predictive value) is uncertain.

    Background: The purposes of this study were to identify changes in tear dimensions, shoulder function, and glenohumeral kinematics when an asymptomatic rotator cuff tear becomes painful and to identify characteristics of individuals who develop pain compared with those who remain asymptomatic. Methods: A cohort of 195 subjects with an asymptomatic rotator cuff tear was prospectively monitored for pain development and examined annually for changes in various parameters such as tear size, fatty degeneration of the rotator cuff muscle, glenohumeral kinematics, and shoulder function. Forty-four subjects were found to have developed new pain, and the parameters before and after pain development were compared. The forty-four subjects were then compared with a group of fifty-five subjects who remained asymptomatic over a two-year period. Results: With pain development, the size of a full-thickness rotator cuff tear increased significantly, with 18% of the full-thickness tears showing an increase of >5 mm, and 40% of the partial-thickness tears had progressed to a full-thickness tear. In comparison with the assessments made before the onset of pain, the American Shoulder and Elbow Surgeons scores for shoulder function were significantly decreased and all measures of shoulder range of motion were decreased except for external rotation at 90° of abduction. There was an increase in compensatory scapulothoracic motion in relation to the glenohumeral motion during early shoulder abduction with pain development. No significant changes were found in external rotation strength or muscular fatty degeneration. Compared with the subjects who remained asymptomatic, the subjects who developed pain were found to have significantly larger tears at the time of initial enrollment. Conclusions: Pain development in shoulders with an asymptomatic rotator cuff tear is associated with an increase in tear size. Larger tears are more likely to develop pain in the short term than are smaller

    The diagnostic significance of single-balloon enteroscopy (SBE) in patients presenting with Crohn's disease (CD)-like anorectal fistula is unknown. We experienced 11 cases undergoing SBE due to CD-like fistulas between December 2007 and April 2013. The mean interval from fistula onset to SBE was 19.2 months with a range of 1.3-44.7. Prior to SBE, all patients underwent anorectal examination under anesthesia (EUA), and 9 patients underwent total colonoscopy with terminal ileal cannulation (TCS-I). One of 7 patients undergoing upper gastrointestinal endoscopy had CD-like gastritis. EUA revealed CD fissures in 7 patients, 1 of whom had no intestinal lesion. Primary TCS-I identified early lesions, such as aphthes and small ulcers, in 4 patients. Among the other 5 patients without any intestinal lesions with TCS-I, SBE indicated early lesions in 3 patients. One of 2 patients who initially underwent SBE without TCS-I showed multiple aphthes. Of the 11 patients, only 4 patients fulfilled the definitive Japanese diagnostic criteria for CD and 7 remained 'suspected CD' cases. Intrinsic anorectal fistulas as a presenting symptom of CD may be an early predictor of bowel lesions. SBE has the potential to reveal incipient disease because an early ileal lesion is not rare for patients with anorectal fistulas.

    AIM: To investigate the spatial distribution patterns of anorectal atresia/stenosis in China. METHODS: Data were collected from the Chinese Birth Defects Monitoring Network (CBDMN), a hospital-based congenital malformations registry system. All fetuses more than 28 wk of gestation and neonates up to 7 d of age in hospitals within the monitoring sites of the CBDMN were monitored from 2001 to 2005. Two-dimensional graph-theoretical clustering was used to divide monitoring sites of the CBDMN into different clusters according to the average incidences of anorectal atresia/stenosis in the different monitoring sites. RESULTS: The overall average incidence of anorectal atresia/stenosis in China was 3.17 per 10 000 from 2001 to 2005. The areas with the highest average incidences of anorectal atresia/stenosis were almost always focused in Eastern China. The monitoring sites were grouped into 6 clusters of areas. Cluster 1 comprised the monitoring sites in Heilongjiang Province, Jilin Province, and Liaoning Province; Cluster 2 was composed of those in Fujian Province, Guangdong Province, Hainan Province, Guangxi Zhuang Autonomous Region, south Hunan Province, and south Jiangxi Province; Cluster 3 consisted of those in Beijing Municipal City, Tianjin Municipal City, Hebei Province, Shandong Province, north Jiangsu Province, and north Anhui Province; Cluster 4 was made up of those in Zhejiang Province, Shanghai Municipal City, south Anhui Province, south Jiangsu Province, north Hunan Province, north Jiangxi Province, Hubei Province, Henan Province, Shanxi Province and Inner Mongolia Autonomous Region; Cluster 5 consisted of those in Ningxia Hui Autonomous Region, Gansu Province and Qinghai Province; and Cluster 6 included those in Shaanxi Province, Sichuan Province, Chongqing Municipal City, Yunnan Province, Guizhou Province, Xinjiang Uygur Autonomous Province and Tibet Autonomous Region. CONCLUSION: The findings in this research allow the display of the spatial distribution

    High-definition anorectal manometry (HDAM-3D) provides a topographic and 3-dimensional profile of anorectal pressure. We assessed anorectal sensorimotor function and the reproducibility of measurements made with HDAM-3D in healthy adults, and the accuracy of data analysis by its software. Anal sphincter pressures and rectal sensory thresholds were measured in 78 healthy subjects via placement of a 10-mm rigid probe, with 256 circumferentially arrayed pressure sensors, and a balloon in the rectum. The bearing down maneuver was assessed in a subset of 18 subjects. We compared data analyzed by an expert with findings from automated software analysis. Measurements made in a subset of 16 subjects, 2 weeks apart, were compared to determine reproducibility. Resting, squeezing, and sustained squeezing pressures were significantly higher in men than in women (P < .05); other parameters were similar. Desire and urgency to defecate were similar between men and women, but the maximal tolerable volume was significantly lower in women (P < .05). Older women (>50 years) had significantly lower resting (P < .01) and sustained squeeze pressures (P < .04). Dyssynergic patterns of defecation were observed in 12 of 18 subjects (67%) who attempted to defecate without the 60-mL rectal balloon distention and in 6 of 18 subjects (33%) with the 60-mL rectal balloon distention. Test-retest values correlated (r = 0.81), as did analyses made by an expert vs software analyses of data (r = 0.99). On the basis of HDAM-3D measurements in healthy adults, anal sphincter pressures are higher in men than in women, but sensory and other parameters are similar; older subjects have weaker sphincters. Many people were found to have dyssynergic patterns of defecation, which could be related to the probe or other technical issues, so this technique may not be suitable for assessing defecation patterns. Measurements made by HDAM-3D are reproducible, and data can be accurately analyzed by its software

    In transrectal rigid-hybrid natural orifice translumenal endoscopic sigmoidectomy (trNS), extraction-site laparotomy is avoided, which reduces postoperative pain and improves recovery time. However, current research evaluating anorectal function after trNS is limited. This study aims to evaluate clinical continence, anorectal manometry, and quality of life in patients undergoing trNS for diverticular disease. Between November 2013 and October 2015, patients undergoing trNS for diverticular disease were prospectively included. Patients converted to laparoscopic resection with an extraction-site laparotomy before attempted transrectal access were excluded. Anorectal manometry, including measurement of resting pressure, squeeze pressure, and retention tests; and questionnaires on continence, defecation, quality of life, and cosmesis, were obtained before and at 3 and 6 months after surgery. Twenty-five patients were enrolled in the study. Four were converted and 1 was lost to follow-up, leaving 20 patients included in the study. Mean anal resting pressure before surgery was 59.3 mmHg (95% CI, 51.81-66.79 mmHg), decreasing to 48.85 mmHg (95% CI, 43.75-53.95 mmHg) at 3 months (p = 0.015). It normalized to 53.45 mmHg (95% CI, 47.78-59.12 mmHg) at 6 months (p = 0.168). Maximum anal squeeze pressure, retention tests, and St Marks incontinence score remained unchanged during the follow-up. Gastrointestinal Quality of Life Index remained high before (124 points) and at 6 months after surgery (128.8 points; p = 0.544). Six months after trNS, neither clinical continence nor manometric findings deteriorated. Quality of life after trNS for recurrent diverticulitis is excellent. Long-term implications of a temporary decline in resting pressure after 3 months remain unclear and warrant long-term follow-up. Copyright © 2016 American College of Surgeons.

    The purpose of the current study was to determine the incidence of sexual stimulation device (SSD)-related injuries among U.S. adults. From 1995 to 2006, 198 individuals (representing a national estimate of 8415 individuals) sought emergency care due to an SSD-related injury to the vaginal, penile, or anorectal body regions. Rates were highest for ages 30-39 (4.26/1,000,000) and 40-49 (3.40/1,000,000), and the rates for men compared to women were particularly high for ages 40 and older. While rare in previous years, the pattern of SSD-related injuries suggests these injuries may become more common and are disproportionately affecting older males.

  10. Management of the asymptomatic BRCA mutation carrier

    2010-01-01

    Current management of an asymptomatic BRCA mutation carrier includes early initiation and intensive cancer screening in combination with risk reduction strategies. The primary objectives of these interventions are earlier detection and cancer prevention to increase quality of life and prolonged survival. Existing recommendations are often based on the consensus of experts as there are few, supportive, randomized control trials. Management strategies for unaffected patients with BRCA mutations are continually redefined and customized as more evidence-based knowledge is acquired with regard to current intervention efficacy, mutation-related histology, and new treatment modalities. This review provides an outline of current, supported management principles, and interventions in the care of the asymptomatic BRCA mutation carrier. Topics covered include surveillance modalities and risk reduction achieved through behavioral modification, chemoprevention, and prophylactic surgery. PMID:23776357

  11. Asymptomatic bacteriuria - prevalence in the elderly population.

    2011-10-01

    To identify the prevalence of asymptomatic bacteriuria in the elderly population and to examine associated risk factors, complications and natural history, and whether treatment improves prognosis. A literature search of MEDLINE, PubMed and the Cochrane Library was undertaken of studies published from 1980 to 2009. A total of 70 articles were identified. Emphasis was given to randomised controlled trials, review articles and more recent publications. Asymptomatic bacteriuria is common in the elderly, especially among institutionalised or hospitalised patients. Risk factors include cognitive impairment, diabetes mellitus, structural urinary tract abnormalities and indwelling catheters. Antimicrobial therapy does not result in improved survival or genitourinary morbidity and may potentially cause avoidable side effects and the emergence of resistant organisms. Bacteriuria is common in functionally impaired elderly patients. In the absence of symptoms or signs of infection, routine dipstick screening and subsequent antimicrobial therapy is not recommended.

    A role of gut-brain axis emerges in the pathophysiology of anorexia nervosa and maintaining adapted physical activity during refeeding remains discussed. We aimed to assess gastrointestinal protein metabolism and investigate the contribution of physical activity during refeeding in C57BL/6 mice with activity-based anorexia (ABA). ABA mice exhibited lower body weight and food intake with increase of lean mass/fat mass ratio and fat oxidation. Colonic permeability was increased in ABA. Ad libitum food access was then restored and ABA group was divided into two subgroups, with access to running wheel (ABA-PA) or not (ABA-NPA). After refeeding, fat free mass was completely restored only in ABA-PA. Colonic permeability was enhanced in ABA-NPA. Finally, muscle kynurenine conversion into kynurenic acid was lower in ABA-NPA who also exhibited altered behavior. Maintaining physical activity during refeeding may thus limit colonic hyperpermeability and improve behavior in anorectic mice.

    Two daily injections of 10 mg/kg salbutamol for 6 days caused complete tolerance in rats to the inhibitory effect on food intake measured 19 h after the last injection. Tolerance was not contingent on the time that elapsed between drug injections and eating during repeated treatment ('physiological' tolerance) and was reversible since the effect of salbutamol on food intake was completely reinstated 5 days after drug discontinuation. The anorectic effects of d-amphetamine and d-fenfluramine were not significantly modified in salbutamol tolerant animals, suggesting that the mechanisms involved in the tolerance to the effect of salbutamol are different from those involved in the effect of d-amphetamine and d-fenfluramine to cause depression of food intake in rats.

    Giant condyloma acuminatum (Buschke-Loewenstein tumor) is an unusual variety of venereal wart characterized by a large size, cauliflower-like appearance, and locally invasive nature. CT examination of two patients with anorectal giant condylomata revealed the papillomatous and invasive nature of the lesion and the extent of tumor; there was infiltration of the subcutaneous tissue, perirectal fascial planes, and luminal narrowing with marked thickening of the rectal wall. The pathologic specimens showed benign histologic finding in one case and a mixed pattern with areas of malignant degeneration in the other. CT accurately demonstrated the exact location and extent of the lesions. The presence of malignant degeneration in this inherently invasive lesion can be established only on histologic examination.

    We report a case of an abandoned abdominal ventriculoperitoneal shunt that migrated into the gastric antrum, colonic hepatic flexure, and liver parenchyma, which was discovered incidentally on an abdominal CT obtained for renal stones. In regards to the migrated abandoned VP shunt, the patient was asymptomatic. Upon review of prior CT scans, these findings had progressed over approximately 7 years. We describe the case and discuss the clinical and radiologic findings, complications resulting from ventriculoperitoneal shunts, and possible approaches to their management.

    Purpose: To compare computed tomography (CT) with positron emission tomography-CT (PET-CT) scans with respect to anorectal tumor volumes, correlation in overlap, and influence on radiation treatment fields and patient care. Patients and Methods: From March to November 2003, 20 patients with rectal cancer and 3 patients with anal cancer were treated with preoperative or definitive chemoradiation, respectively. Computed tomography simulation data generated a CT gross tumor volume (CT-GTV) and CT planning target volume (CT-PTV) and {sup 18}F-fluoro-2-deoxy-glucose PET (FDG-PET) created a PET-GTV and PET-PTV. The PET-CT and CT images were fused using manual coregistration. Patients were treated with three-dimensional conformal therapy to traditional doses. The PET, CT, and overlap volumes (OVs) were measured in cubic centimeters. Results: Mean PET-GTV was smaller than the mean CT-GTV (91.7 vs. 99.6 cm{sup 3}). The mean OV was 46.7%. As tumor volume increased, PET and CT OV correlated significantly (p < 0.001). In 17% of patients PET-CT altered the PTV, and in 26% it changed the radiation treatment plan. For 25% of patients with rectal cancer, PET detected distant metastases and changed overall management. Ten rectal cancer patients underwent surgery. When the pretreatment PET standardized uptake value was >10 and the posttreatment PET standardized uptake value was <6, 100% achieved pathologic downstaging (p = 0.047). Conclusions: Variation in volume was significant, with 17% and 26% of patients requiring a change in treatment fields and patient management, respectively. Positron emission tomography can change the management for anorectal tumors by early detection of metastatic disease or disease outside standard radiation fields.

    Background & Aims The anal sphincters and puborectalis are routinely imaged with an endoanal magnetic resonance imaging (MRI) coil, which does not assess co-aptation of the anal canal at rest. Using a MRI torso coil, we identified a patulous anal canal in some patients with anorectal disorders. We aimed to evaluate the relationship between anal sphincter and puborectalis injury, a patulous anal canal, and anal pressures. Methods We performed a retrospective analysis of data from 119 patients who underwent MRI and manometry analysis of anal anatomy and pressures, respectively, from February 2011 through March 2013 at the Mayo Clinic. Anal pressures were determined by high-resolution manometry, anal sphincter and puborectalis injury was determined by endoanal MRI, and anal canal integrity was determined by torso MRI. Associations between manometric and anatomical parameters were evaluated with univariate and multivariate analyses. Results Fecal incontinence (55 patients, 46%) and constipation (36 patients. 30%) were the main indications for testing; 49 patients (41%) had a patulous anal canal, which was associated with injury to more than 1 muscle (all P≤.001) and internal sphincter (P<.01), but not puborectalis (P=.09) or external sphincter (P=.06) injury. Internal (P<.01) and external sphincter injury (P=.02) and a patulous canal (P<.001), but not puborectalis injury, predicted anal resting pressure. A patulous anal canal was the only significant predictor (P<.01) of the anal squeeze pressure increment. Conclusions Patients with anorectal disorders commonly have a patulous anal canal, associated with more severe anal injury, anal resting pressure, and squeeze pressure increment. It is therefore important to identify patulous anal canal because it appears to be a marker of not only anal sphincter injury but disturbances beyond sphincter injury, such as damage to the anal cushions or anal denervation.

Internal (P < .01) and external sphincter injury (P = .02) and a patulous canal (P < .001), but not puborectalis injury, predicted anal resting pressure. A patulous anal canal was the only significant predictor (P < .01) of the anal squeeze pressure increment.

    The cloaca is temporally formed and eventually divided by the urorectal septum (URS) during urogenital and anorectal organ development. Although congenital malformations, such as anorectal malformations (ARMs), are frequently observed during this process, the underlying pathogenic mechanisms remain unclear. β-Catenin is a critical component of canonical Wnt signaling and is essential for the regulation of cell differentiation and morphogenesis during embryogenesis. The expression of β-catenin is observed in endodermal epithelia, including URS epithelia. We modulated the β-catenin gene conditionally in endodermal epithelia by utilizing tamoxifen-inducible Cre driver line (ShhCreERT2). Both β-catenin loss- and gain-of-function (LOF and GOF) mutants displayed abnormal clefts in the perineal region and hypoplastic elongation of the URS. The mutants also displayed reduced cell proliferation in the URS mesenchyme. In addition, the β-catenin GOF mutants displayed reduced apoptosis and subsequently increased apoptosis in the URS epithelium. This instability possibly resulted in reduced expression levels of differentiation markers, such as keratin 1 and filaggrin, in the perineal epithelia. The expression of bone morphogenetic protein (Bmp) genes, such as Bmp4 and Bmp7, was also ectopically induced in the epithelia of the URS in the β-catenin GOF mutants. The expression of the Msx2 gene and phosphorylated-Smad1/5/8, possible readouts of Bmp signaling, was also increased in the mutants. Moreover, we introduced an additional mutation for a Bmp receptor gene: BmprIA. The ShhCreERT2/+; β-cateninflox(ex3)/+; BmprIAflox/− mutants displayed partial restoration of URS elongation compared with the β-catenin GOF mutants. These results indicate that some ARM phenotypes in the β-catenin GOF mutants were caused by abnormal Bmp signaling. The current analysis revealed the close relation of endodermal β-catenin signaling to the ARM phenotypes. These results are considered to

    The anorectic anx/anx mouse exhibits a mitochondrial complex I dysfunction that is related to aberrant expression of hypothalamic neuropeptides and transmitters regulating food intake. Hypothalamic activity, i.e. neuronal firing and transmitter release, is dependent on glucose utilization and energy metabolism. To better understand the role of hypothalamic activity in anorexia, we assessed carbohydrate and high-energy phosphate metabolism, in vivo and in vitro, in the anx/anx hypothalamus. In the fasted state, hypothalamic glucose uptake in the anx/anx mouse was reduced by ~50% of that seen in wild-type (wt) mice (P < 0.05). Under basal conditions, anx/anx hypothalamus ATP and glucose 6-P contents were similar to those in wt hypothalamus, whereas phosphocreatine was elevated (~2-fold; P < 0.001) and lactate was reduced (~35%; P < 0.001). The anx/anx hypothalamus had elevated total AMPK (~25%; P < 0.05) and GLUT4 (~60%; P < 0.01) protein contents, whereas GLUT1 and GLUT3 were similar to that of wt hypothalamus. Interestingly, the activation state of AMPK (ratio of phosphorylated AMPK/total AMPK) was significantly decreased in hypothalamus of the anx/anx mouse (~60% of that in wt; P < 0.05). Finally, during metabolic stress (ischemia), accumulation of lactate (measure of glycolysis) and IMP and AMP (breakdown products of ATP) were ~50% lower in anx/anx vs wt hypothalamus. These data demonstrate that carbohydrate and high-energy phosphate utilization in the anx/anx hypothalamus are diminished under basal and stress conditions. The decrease in hypothalamic metabolism may contribute to the anorectic behavior of the anx/anx mouse, i.e. its inability to regulate food intake in accordance with energy status. © 2017 Society for Endocrinology.

    Behavioral studies have suggested that (p-ClPhSe)2 elicits an anorectic-like action in rats by inducing multiple effects such as satiety-enhancing effect, malaise and specific flavor; however, the molecular mechanisms underlying its anorexigenic action remain unclarified. Here, male Sprague-Dawley rats received acute and sub-chronic intraperitoneal treatments with (p-ClPhSe)2; thereafter, in vivo and ex vivo analyses were carried out. The present study reveals that the reduction of food intake resulting from a single treatment with (p-ClPhSe)2 (1mg/kg, i.p.) was associated with decreased hypothalamic levels of pro-melanin-concentrating hormone (pro-MCH) and orexin precursor. In addition, repeated administrations of (p-ClPhSe)2 (10mg/kg; i.p.) for 7 days induced sustained food intake suppression, body weight loss and white fat reduction. Measurements of brown adipose tissue content and temperature as well as data obtained from a pair-fed group indicated that the effects of (p-ClPhSe)2 on the body weight are closely related to its anorexigenic actions, ruling out the possibility of increased thermogenesis. Furthermore, (p-ClPhSe)2 reduced the hypothalamic orexin precursor levels when repeatedly administered to rats. Sub-chronic treatment with (p-ClPhSe)2 caused a decrease of serum triglyceride levels and down-regulation of hepatic cholesterol content. Therefore, the current study characterized the anorectic and reducing body weight actions of (p-ClPhSe)2 in Sprague-Dawley rats. Besides, the set of results suggests that food intake suppressant effects triggered after (p-ClPhSe)2 administration to rats are mainly related with the lower orexin levels in hypothalamus after acute and sub-chronic treatments.

    The study involved 120 young males (aged 20.5 +/- 2.5 years) having undergone successful kidney biopsy because of asymptomatic haematuria with the aims to assess the prevalence of histological diagnosis and the natural history of the disease. The patients were selected from the population of conscripts who were referred to our clinic as a result of asymptomatic microhaematuria. All patients had a negative history of kidney disease, normal creatinine clearance (Ccr), while extrarenal causes of microhaematuria were excluded. The patients were divided into a group of 62 patients with isolated microhaematuria (IMH; proteinuria < 0.3 g/day) and a group of 58 patients with asymptomatic microhaematuria and proteinuria (AMHP; proteinuria > 0.3 g/day). After kidney biopsy patients were monitored for 3-9 years. Normal biopsies and minor abnormalities were more frequent in IMH than in AMHP patients, who had IgA nephritis more frequently and significantly higher total pathohistological score. Based on the clinical and histological features, recommendations on patients' ability for military service were made. During the follow-up period, normal Ccr maintained in all patients. Macrohaematuria appeared in 42 patients and proteinuria worsened in eight patients (seven with AMHP). Urinary abnormalities disappeared in 20 patients with IMH and in eight with AMHP (p = 0.04). Minimal histological changes and disappearance of urinary abnormalities were more frequent in IMH than in AMHP patients. Kidney biopsy is useful only in patients with AMHP but it is not necessary in IMH patients.

    Although routine screening for bladder cancer is not recommended, microscopic hematuria is often incidentally discovered by primary care physicians. The American Urological Association has published an updated guideline for the management of asymptomatic microscopic hematuria, which is defined as the presence of three or more red blood cells per high-power field visible in a properly collected urine specimen without evidence of infection. The most common causes of microscopic hematuria are urinary tract infection, benign prostatic hyperplasia, and urinary calculi. However, up to 5% of patients with asymptomatic microscopic hematuria are found to have a urinary tract malignancy. The risk of urologic malignancy is increased in men, persons older than 35 years, and persons with a history of smoking. Microscopic hematuria in the setting of urinary tract infection should resolve after appropriate antibiotic treatment; persistence of hematuria warrants a diagnostic workup. Dysmorphic red blood cells, cellular casts, proteinuria, elevated creatinine levels, or hypertension in the presence of microscopic hematuria should prompt concurrent nephrologic and urologic referral. The upper urinary tract is best evaluated with multiphasic computed tomography urography, which identifies hydronephrosis, urinary calculi, and renal and ureteral lesions. The lower urinary tract is best evaluated with cystoscopy for urethral stricture disease, benign prostatic hyperplasia, and bladder masses. Voided urine cytology is no longer recommended as part of the routine evaluation of asymptomatic microscopic hematuria, unless there are risk factors for malignancy.

  5. The Paradigm Shift to Non-Treatment of Asymptomatic Bacteriuria

    Asymptomatic bacteriuria, also called asymptomatic urinary infection, is a common finding in healthy women, and in women and men with abnormalities of the genitourinary tract. The characterization and introduction of the quantitative urine culture in the 1950s first allowed the reliable recognition of asymptomatic bacteriuria. The observations that a substantial proportion of patients with chronic pyelonephritis at autopsy had no history of symptomatic urinary infection, and the high frequency of pyelonephritis observed in pregnant women with untreated asymptomatic bacteriuria, supported a conclusion that asymptomatic bacteriuria was harmful. Subsequent screening and long term follow-up programs for asymptomatic bacteriuria in schoolgirls and women reported an increased frequency of symptomatic urinary tract infection for subjects with asymptomatic bacteriuria, but no increased morbidity from renal failure or hypertension, or increased mortality. Treatment of asymptomatic bacteriuria did not decrease the frequency of symptomatic infection. Prospective, randomized, comparative trials enrolling premenopausal women, children, elderly populations, patients with long term catheters, and diabetic patients consistently report no benefits with antimicrobial treatment of asymptomatic bacteriuria, and some evidence of harm. Several studies have also reported that antimicrobial treatment of asymptomatic bacteriuria increases the short term risk of pyelonephritis. Current investigations are exploring the potential therapeutic intervention of establishing asymptomatic bacteriuria with an avirulent Escherichia coli strain to prevent symptomatic urinary tract infection for selected patients.

    Integrating sexual health in clinical practice is important. In women with pelvic floor disorders, the evaluation of the anatomical defects, lower urinary tract function and the anorectal function often receives more attention than the sexual function. Review of Medline using defined search terms to identify articles related to sexual health assessment in urogynecology and manual analyses was performed. Only articles published in English or Spanish were included. Only 50% of women attending urogynecological clinics are sexually active. Of those, 60% present with some sort of sexual sexual dysfunction (FSD). Questionnaires and sexuality scales would facilitate discussion of sexual matters between the Health Care professionals and the women, and may increase the likelihood of FSD being diagnosed. The Pelvic Organ Prolapse Incontinence Sexual Questionnaire (PISQ) and the PISQ-IR (IUGA-Revised) are the only female sexual function specific questionnaires currently validated and developed specifically to assess sexual function in women with urinary incontinence and/or pelvic organ prolapse. Furthermore, the PISQ-IR also allows evaluation of the outcomes of women who are not sexually active when requiring urogynecologic care. PISQ-IR is also designed for international validation. In order to use the PISQ-IR in Spain, a proper interpretation and validation of the questionnaire is needed. The evaluation of sexual function through specific questionnaires facilitates the identification of the sexual dysfunctions associated to the pelvic floor disorders. The inclusion of sexuality questionnaires as an outcome measure allows to analyze the impact in the sexual life of women treated for an urogynecological problem. Copyright © 2014 AEU.

    The aim was to review the literature on genito-urinary dysfunction in multiple sclerosis (MS). A literature review through the PubMed library until August, 31 2013 was carried out using the following keywords: multiple sclerosis and neurogenic bladder, neuropathic bladder, bladder, management, follow-up, urological complications, urological treatment, sexual dysfunction, female sexual function, male sexual function, erectile dysfunction, anorectal, faecal, constipation, bowel, pregnancy, parturition, delivery, breast-feeding. Genito-urinary dysfunction is frequent in MS (35-90%) and may happen soon in the disease. Urinary symptoms (10-90%) are manifold resulting in a quality of life alteration and the onset of complications in 30% of the cases requiring a long-term follow-up. Sexual dysfunctions (35-87%) are also manifold affecting all the sexuality domains in men and women. Except the phosphodiesterase V inhibitors, few treatments have been assessed in this population. Pregnancy is nowadays considered as beneficial resulting in a disease slow-down and the lack of disease worsening despite an increase in disease relapse during the post-partum first quarter. It seems to be better to consider getting pregnant after at least one year without any relapse and to emphasize an exclusive breast-feeding. Urinary and sexual dysfunctions are frequent in MS. A transdisciplinary approach including the neurologist and pelviperineology specialists facilitates a disability adapted early management. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Using the German self-help organization for people with anorectal malformations (SoMA e.V.) as an example, the aim is to illustrate the particular importance of selfhelp groups for rare diseases. First, the structure and work of the German support and advocacy organization are explained by means of a case study. The special benefit for people affected with a rare disease and their relatives, but also for medical practitioners and health insurance funds are highlighted. Synergetic effects by integrating networks are presented. Meanwhile and thanks to globalization and internet, 13 national self-help groups for anorectal malformations and related continence problems are currently in touch. Even today, the fields of activity and the mutual support in coping with the handicap are frequently underestimated. Professional self-help aims to be respected as an equal partner in interdisciplinary health care systems.

    Purpose: To study the correlations between the dose distributions in the anorectal region and late GI symptoms in patients treated for localized prostate carcinoma. Methods and materials: Data from a randomized study were analyzed. In this trial, patients were treated with either rectangular or conformal fields with a dose of 66 Gy. Data concerning GI symptoms were collected from questionnaires of 197 patients. The distributions of the anorectal region were projected on maps, and the dose parameters were calculated. The incidences of complaints were studied as a function of the dose-area parameters and clinical parameters, using a proportional hazard regression model. Finally, we tested a series of dose parameters originating from different parts of the anorectal region. Results: Analyzing the total region, only a statistically significant dose-area effect relation for bleeding was found (p < 0.01). Defining subareas, we found effect relations for bleeding, soiling, fecal incontinence, and mucus loss. For bleeding and mucus loss, the strongest correlation was found for the dose received by the upper 70-80% of the anorectal region (p < 0.01). For soiling and fecal incontinence, we found the strongest association with the dose to the lower 40-50% (p < 0.05). Conclusion: We found evidence that complaints originate from specific regions of the irradiated lower GI tract. Bleeding and mucus loss are probably related to irradiation of the upper part of the rectum. Soiling and fecal incontinence are more likely related to the dose to the anal canal and the lower part of the rectum.

  12. Management of complex anorectal fistulas with seton drainage plus partial fistulotomy and subsequent ligation of intersphincteric fistula tract (LIFT).

    Ligation of intersphincteric fistula tract (LIFT) is a relatively new technique in the treatment of complex anorectal fistulas. As it spares the anal sphincter, rates of post-operative incontinence may be lower when compared to conventional treatment. To date, there have not been enough reports of long-term fistula recurrence rates. We performed a long-term follow-up study of 75 patients who underwent LIFT following seton drainage and partial fistulotomy. Only patients with complex cryptogenic anorectal fistulas were included. After seton insertion and partial fistulotomy, the tract was reviewed at 4 months for the absence of anorectal sepsis. Patients then underwent LIFT in a day surgery setting. Operative time, complications, recurrences and incontinence were evaluated. Between May 2008 and June 2013, 75 patients [51 men, mean age 49.5 years, standard error of the mean (SEM) 1.4 years] were treated with a LIFT protocol. The mean operating time for LIFT was 13.2 min (SEM 1.5 min). Complications included minor bleeding, superficial wound dehiscence and perianal pain. At a mean follow-up of 14.6 months (SEM 1.7 months), there were nine (12 %) recurrences, diagnosed at a mean 9.2 months (SEM 2.7 months). They were treated with seton insertion followed by LIFT with biomesh or anorectal advancement flap, and there were no subsequent recurrences. Review of preoperative and post-operative continence scores revealed only one (1.3 %) patient with minor incontinence following LIFT. Recurrences were significantly related to fistulas with multiple tracts (p < 0.001). Our results suggest that the protocol of seton insertion and partial fistulotomy followed by LIFT is associated with a low recurrence rate comparing well with published results from studies involving other techniques and protocols for treating anal fistula.

    Although perianal streptococcal dermatitis (PSD) is well known in children, it has only rarely been documented in adults. The incidence and necessity for treatment may be underestimated. We have retrospectively identified adult patients with perianal streptococcal dermatitis. Patients with streptococcal anal dermatitis were identified from a prospective office database. Treatment was with oral antibiotics according to the organism sensitivity. Additional concomitant anorectal disease was treated according to standard guidelines. Patients were compared with a control group, without eczema or erythema, for the presence of β-haemolysing Streptococci on perianal swab. Demographic and microbiological data were assessed and compared between and within treatment and control groups. Fifty-three (22 female) patients older than 20 (mean = 49) years of age were diagnosed with perianal streptococcal dermatitis between 2005 and 2009. In most cases group B β-haemolytic Streptococci were found. Fifty patients received antibiotics for 14 days. In 28 of 33 patients who had a post-treatment swab, the result was negative. Five patients showed Streptococci of different groups in the post-treatment swab. Of the 50 patients, 21 (42%) had no further anorectal complaint and 29 (58%) required continuing treatment for another anorectal condition. In the control group β-haemolysing Streptococcus was found in 34%. Men over 60 years of age more often required no further anorectal treatment compared with women (P < 0.05). Perianal streptococcal dermatitis occurs in adult patients more often than reported. It is mainly caused by group B β-haemolysing Streptococcus. Its diagnosis is important because it can cause serious systemic infections, especially in the elderly and in newborns. Antibiotics resolve the condition in a high proportion of patients. © 2012 The Authors. Colorectal Disease © 2012 The Association of Coloproctology of Great Britain and Ireland.

    2014-02-01

    Use of medications for attention-deficit hyperkinetic disorder and preparticipation sports physical examination has led to an increase in number of electrocardiograms (ECG) performed during adolescence. Interpreting ECGs in children and young adults must take into account the evolutionary changes with age and the benign variants, which are usually not associated with heart disease. It is crucial for primary-care providers to recognize the changes on ECG associated with heart disease and risk of sudden death. In this article, the significance, sensitivity, specificity, and the diagnostic workup of these findings in the asymptomatic teenager are discussed.

    Asymptomatic bacteriuria occurs in 2% to 10% of pregnancies and, if not treated, up to 30% of mothers will develop acute pyelonephritis. Asymptomatic bacteriuria has been associated with low birthweight and preterm birth. To assess the effect of antibiotic treatment for asymptomatic bacteriuria on the development of pyelonephritis and the risk of low birthweight and preterm birth. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (19 March 2015) and reference lists of retrieved studies. Randomized trials comparing antibiotic treatment with placebo or no treatment in pregnant women with asymptomatic bacteriuria found on antenatal screening. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Fourteen studies, involving almost 2000 women, were included. Antibiotic treatment compared with placebo or no treatment reduced the incidence of pyelonephritis (average risk ratio (RR) 0.23, 95% confidence interval (CI) 0.13 to 0.41; 11 studies, 1932 women; very low quality evidence). Antibiotic treatment was also associated with a reduction in the incidence of low birthweight babies (average RR 0.64, 95% CI 0.45 to 0.93; six studies, 1437 babies; low quality evidence) and preterm birth (RR 0.27, 95% CI 0.11 to 0.62; two studies, 242 women; low quality evidence). A reduction in persistent bacteriuria at the time of delivery was seen (average RR 0.30, 95% CI 0.18 to 0.53; four studies; 596 women). There were very limited data on which to estimate the effect of antibiotics on other infant outcomes and maternal adverse effects were rarely described.Overall, all 14 studies were assessed as being at high or unclear risk of bias. While many studies lacked an adequate description of methods and the risk of bias could only be assessed as unclear, in almost all studies there was at least one domain where the risk of bias was judged as high. The three primary outcomes were assessed with

    To explore the pathogenesis of ano-rectal diseases caused by deficiency of Qi, which is correlated with obstruction of pulmonary ventilation. The pulmonary ventilatory function was measured in 100 patients with the internal piles, the interno-external hemorrhoid and prolapse of rectum, the prolapse of anus was the principal symptom of them. Data from the 100 patients showed that 67% of them were diagnosed with the obstruction of pulmonary ventilation, the ratio was far less in the health control group. FEV 1.0 (mean +/- s) (2011.65 +/- 875) ml, MMF (1.84 +/- 1.24) L/s and PEF (2.34 +/- 1.51) L/s in male patients, (1551.54 +/- 514) ml, (1.57 +/- 0.62) L/s and (1.85 +/- 0.92) L/s in female patients, but those values were higher in the control than in the patients. The statistical analysis was performed and the difference was significant between patients and the control group (P < 0.01). The patients with ano-rectal diseases caused by deficiency of Qi accompanied with obstruction of pulmonary ventilation in different degree and varied sorts, it confirmed that the pathogenesis of ano-rectal diseases caused by deficiency of Qi is related with "sinking of pectoral Qi".

    To evaluate growth and development in children with anorectal malformations and to analyze effects of type of malformation and comorbidities. Non-syndromal children with anorectal malformations were prospectively evaluated at 0.5, 1, 2, and 5 years. Biometrics were obtained at all visits. Mental and psychomotor function development was determined. 108 children (59% male) were included. 49% had a high malformation, and 46% had ≥ 1 additional major comorbidity. All growth parameters were below the norm at all ages (p<0.01), irrespective of type of malformation. Children with ≥ 1 additional major anomaly had lower height at all ages; at 5 years, mean (95% CI) height was -1.83 (-2.7 to -1.1) and -0.70 (-1.3 to -0.1) in children with and without comorbidities, respectively (p=0.019). Mental development was normal, irrespective of the type of malformation or comorbidities. Motor development was delayed at all ages. At 5 years, motor development (n=30) was normal in 70%, borderline in 23%, and 7% had definitive motor problems (p=0.043). Non-syndromal children with anorectal malformations are at risk for growth impairment, especially those with additional major comorbidity. Mental development is normal. Motor development is slightly impaired. Supportive care should focus on growth, dietary management, and motor development besides defecation problems. Copyright © 2013 Elsevier Inc.

    The role for c-Jun N-terminal Kinase (JNK) in the control of feeding and energy balance is not well understood. Here, by use of novel and highly selective JNK inhibitors, we investigated the actions of JNK in the control of feeding and body weight homeostasis. In lean mice, intraperitoneal (i.p.) or intracerebroventricular (i.c.v.) administration of SR-3306, a brain-penetrant and selective pan-JNK (JNK1/2/3) inhibitor, reduced food intake and body weight. Moreover, i.p. and i.c.v. administrations of SR11935, a brain-penetrant and JNK2/3 isoform-selective inhibitor, exerted similar anorectic effects as SR3306, which suggests JNK2 or JNK3 mediates aspect of the anorectic effect by pan-JNK inhibition. Furthermore, daily i.p. injection of SR3306 (7 days) prevented the increases in food intake and weight gain in lean mice upon high-fat diet feeding, and this injection paradigm reduced high-fat intake and obesity in diet-induced obese (DIO) mice. In the DIO mice, JNK inhibition sensitized leptin's anorectic effect, and enhanced leptin-induced STAT3 activation in the hypothalamus. The underlying mechanisms likely involve the downregulation of SOCS3 by JNK inhibition. Collectively, our data suggest that JNK activity promotes positive energy balance, and the therapeutic intervention inhibiting JNK activities represents a promising approach to ameliorate diet-induced obesity and leptin resistance.

    Benign anorectal disease comprises a broad group of processes with very diverse origins; these processes may be congenital or acquired as well as inflammatory or tumor related. However, benign anorectal disease has received less attention in the scientific literature than malignant disease. In this second part of this image-based review of benign anorectal disease, we describe the most common inflammatory and fistulous diseases, the postsurgical anatomy, and complications that can occur after surgical treatment or radiotherapy for anorectal disease.

    Asymptomatic spontaneous nephrocutaneous fistula is a rare and severe complication of chronic urolithiasis. We report a case of 56-year-old woman with a nephrocutaneous fistula (NFC) which developed from a superinfected urinoma following calyceal rupture due to an obstructing calculus in the left ureter. The patient was clinically asymptomatic and came to the emergency department for a painless left flank fluctuating mass. This urinoma was superinfected, with a delayed development of renal abscesses and perirenal phlegmon found on contrast-enhanced uro-computed tomography (CT), responsible for left renal vein thrombophlebitis and left psoas abscess. Thereafter, a 99 mTc dimercaptosuccinic acid (DMSA) scintigraphy revealed a nonfunctional left kidney, leading to the decision of left nephrectomy. Chronic urolithiasis complications are rare and only few cases are reported in medical literature. A systematic medical approach helped selecting the best imaging modality to help diagnosis and treatment. Indeed, uro-CT scan and renal scintigraphy with 99 mTc-DMSA are the most sensitive imaging modalities to investigate morphological and functional urinary tract consequences of NFC, secondary to chronic urolithiasis.

    Asymptomatic spontaneous pneumothorax (ASPT) is an uncommon condition. Between January 1, 1989 and December 31, 1997, 269 patients were admitted to our department with spontaneous pneumothorax. Of the 269 patients, 5 had no symptoms at the time of discovery. Their ages ranged from 15 to 61 years (mean, 37.8 years), and all of them were male. Of the 5 patients with no complaints, 2 had bilateral metachronous pneumothoraces and 3 had hemilateral pneumothorax. All of these ASPTs were revealed by chest roentgenographs taken during medical examinations or follow-up studies relating to other diseases. The mean value of body mass index (BMI) was 19.96 +/- 1.4 (range 18.7 - 22.1). Two of the 5 patients underwent bilateral partial lung resection. Histopathological examination of the resected specimens showed elastofibrosis, scar formation, and an interruption of the elastic fiber of the pleura. In these 5 cases, clinical courses were uneventful, and relapse of the pneumothorax did not occur. Clinical physicians should be aware of the possibility of asymptomatic pneumothorax, as well as the optimal radiographic techniques for revealing small pneumothoraces.

    Biotinidase deficiency is an autosomal-recessive disorder of biotin recycling. Children with profound biotinidase deficiency usually have neurological and cutaneous symptoms in early childhood, but they may not develop symptoms until adolescence. We now report on a man and a woman with profound biotinidase deficiency who are asymptomatic and who were diagnosed only because their biotinidase-deficient children were identified by newborn screening. These adults have never exhibited symptoms of the disorder and are homozygous for two different mutations resulting in different aberrant enzymes. There is no evidence of an increased dietary intake of biotin to explain why they have remained asymptomatic. Although these adults may still be at risk for developing symptoms, they could represent a small group of individuals with profound biotinidase deficiency who will never develop clinical problems. Their lack of symptoms suggests that there are probably epigenetic factors that protect some enzyme-deficient individuals from developing symptoms. These individuals broaden the spectrum of expression of biotinidase deficiency.

    Anorectal malformations (ARMs) comprise a range of defects in the development of the lowest portion of the intestinal tract that are often associated with anomalies of the urinary tract. We hypothesize that ARMs may specifically predispose the patients to prolonged urinary tract infection (UTI) and transition from a state of active (clinically apparent) inflammation to a state of latent inflammation following antibiotic treatment. Yet diagnosis of latent inflammation in the urinary tract is problematic. The aim was to investigate the urinary levels of proinflammatory (IL-1β, IL-6, IL-8, and MCP-1), anti-inflammatory (IL-10), and proangiogenic (VEGF) cytokines in the clinical course of chronic pyelonephritis (CP) as potential biomarkers of latent inflammation in the urinary tract in children with ARM. A total of 34 children (age range 4-120 months) with CP in the active phase of inflammation were divided into two groups: CP with ARM group included 20 patients and CP without ARM group included 14 patients. The control group included 20 healthy children similar by age and gender. Urine samples were collected at the time of enrollment, 5-7 days after institution of antibiotic treatment, and 1.5 months after enrollment. Cytokine concentrations were measured by ELISA. Upon enrollment, we detected increased urinary levels of IL-10 and MCP-1 and normal levels of IL-1β, IL-6, IL-8, and VEGF in CP with ARM patients as well as normal levels of all of these cytokines in CP without ARM patients. After 5-7 days of antibiotic treatment, despite significant clinical and laboratory improvement observed in both patient groups, we documented a prominent increase in the urinary concentrations of all measured cytokines indicating ongoing inflammation in the urinary tract. Following 1.5 months of enrollment, in CP without ARM patients, IL-8 and MCP-1 were increased, IL-1, IL-6, and VEGF were close to control, and IL-10 was below the control level, indicating partial resolution of the

    Zika virus (ZIKV) transmission through semen donation has never been reported but the risk is supported by the detection of ZIKV in semen and the demonstration of ZIKV sexual transmission. The potential impact of ZIKV on assisted reproductive procedures should be evaluated. We tested longitudinally collected semen samples provided by asymptomatic blood donors who tested positive for ZIKV RNA in plasma during ZIKV outbreaks in Puerto Rico and Florida in 2016. Five of the 14 (35.7%) asymptomatic blood donors provided semen samples that tested positive for ZIKV RNA, with ZIKV RNA loads ranging from 8.03 × 10(3) to 2.55 × 10(6) copies/mL. Plasma collected at the same time as the semen tested negative for ZIKV RNA for most ZIKV RNA-positive semen collections; all corresponding plasma samples tested positive or equivocal for anti-ZIKV IgG antibodies and all except one tested positive for ZIKV IgM antibodies. The rate of detection of ZIKV RNA in semen in asymptomatic donors is not significantly different from the rate previously reported for symptomatic patients. Our results that show a high percentage of detection of ZIKV RNA in the semen of asymptomatic men confirm that ZIKV is a new threat for reproductive medicine and should have important implications for assisted reproductive technology. We recommend that semen donations from men at risk for ZIKV infection should be tested for ZIKV RNA, regardless of symptoms of ZIKV infection. Copyright © 2017 The Authors.

    Human brucellosis is mainly caused by contact with Brucella-infected animals and their secretions and carcasses. Individuals who are continuously in contact with animals are considered to be at a high risk but only some show symptoms and are diagnosed as cases of brucellosis. Here, we showed that asymptomatic brucellosis infections occur among humans. Asymptomatic infections mainly result from less frequent contact with Brucella and/or contact with low-virulence Brucella. In our study, patients with asymptomatic infection had low antibody titres and different contact patterns. Awareness of asymptomatic infection is important for early diagnosis of brucellosis and prevention of chronic infection.

    Sex is a motive force bringing a man and a woman into intimate contact. Sexuality is a central aspect of being human throughout life and encompasses sex, gender identities and roles, sexual orientation, eroticism, pleasure, intimacy, and reproduction. Sexuality is experienced and expressed in thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles and relationships. Though generally, women are sexually active during adolescence, they reach their peak orgasmic frequency in their 30 s, and have a constant level of sexual capacity up to the age of 55 with little evidence that aging affects it in later life. Desire, arousal, and orgasm are the three principle stages of the sexual response cycle. Each stage is associated with unique physiological changes. Females are commonly affected by various disorders in relation to this sexual response cycle. The prevalence is generally as high as 35–40%. There are a wide range of etiological factors like age, relationship with a partner, psychiatric and medical disorders, psychotropic and other medication. Counseling to overcome stigma and enhance awareness on sexuality is an essential step in management. There are several effective psychological and pharmacological therapeutic approaches to treat female sexual disorders. This article is a review of female sexuality. PMID:26330647

    To develop the first consensus to standardize the management of patients with Anorectal Malformations (ARMs) transitioning from childhood to adulthood. A dedicated task force of experts performed an extensive literature review and multiple meetings to define the most important aspects of transition of care. The findings were discussed with all ARM-net consortium members and a set of practical recommendations agreed upon at the annual meeting in 2016. We defined seven domains that are essential to provide an effective and practical transition process. Within each domain we have developed a set of key recommendations that are important to be considered for ARM patients entering the age of transition. It is crucial that transition begins at an early age with regular and well-structured follow-up. Cooperation with a selected multidisciplinary team of pediatric and adult practitioners is required to prepare patients and families for effective transition to adult care and to reduce long term morbidity.

    The aim of the study was to assess current international practice in the long term follow-up, in managing active problems and transition of care for teenagers born with anorectal malformations (ARM). An original survey was administered to delegates attending two large colorectal surgical meetings in 2015. The 21 questions covered long term follow-up, specific issues for teenagers and transition of care. 96/236 delegates completed the survey. Follow-up was routinely suspended before 10 year of age by 33% of respondents. 90% of them did not use a scoring system to assess or risks stratify patients, despite 81% stating that an objective score would be beneficial. 40% of respondents felt that >30% of their teenagers had ongoing active medical or psychosocial issues. 42% thought their patients were not ready to be transitioned. The process of transition should start around 13-16 years according to 54% of respondents. 72% had no protocol for transition and 82% did not hold multidisciplinary meetings with adult practitioners before transition. International consensus on the following aspects of the care in ARM is needed: structured long term follow-up, objective assessment and risk stratification scores, pathways of transition and methods to prepare patients, parents and adult practitioners.

    Although fluoxetine is a highly selective inhibitor of serotonin uptake in vitro and in vivo, some investigators have suggested that dopamine uptake inhibition may contribute to anorectic actions of fluoxetine. The present experiments were done to determine fluoxetine's effects in some animal protocols in which dopamine uptake inhibitors have characteristic actions. Mazindol prevented the depletion of striatal dopamine and its metabolites by amphetamine in iprindole-pretreated rats, but fluoxetine had no effect. Mazindol prevented the depletion of striatal dopamine and its metabolites by 6-hydroxydopamine injected intracerebroventricularly into rats, but fluoxetine had no effect. Mazindol enhanced the elevation of 3,4-dihydroxyphenylacetic acid concentration in rat brain after spiperone injection, but fluoxetine did not cause that effect. Fluoxetine did not mimic amfonelic acid in antagonizing the retention of alpha-methyl-m-tyramine invant striatum after the injection of alpha-methyl-m-tyrosine. These results show that fluoxetine, at doses that are effective in blocking the serotonin uptake carrier and causing anorexia, does not block the dopamine uptake carrier.

    Congenital anorectal malformation (ARM) is one of the most common gastrointestinal congenital diseases, accounting for 1/4 in digestive tract malformation, and is one of the congenital malformations in routine surveillance by the World Health Organization. Because of the variety of risk factors and the complexity of the pathological changes, etiology of ARM is still not clear. It is mostly considered that ARM is resulted from hereditary factors and environmental factors in the development of embryogenesis. Through animal experiments, scholars have found that Hox, Shh, Fgf, Wnt, Cdx and TCF4, Eph and ephrin play crucial role during the development of digestive tract. When the genes/signaling pathway dysfunction occurs, ARM may happen. In addition, ARM is related to the external factors in pregnancy. Because of the complexity of related factors in the development of human embryogenesis, the research progress of human ARM is very slow. This paper reviews relevant literatures in genetic factors and environmental factors, in order to provide the theoretical basis for the treatment and prevention of ARM.

    The division of the embryonic cloaca is the most essential event for the formation of digestive and urinary tracts. The defective development of the cloaca results in anorectal malformations (ARMs; 2–5 per 10,000 live births). However, the developmental and pathogenic mechanisms of ARMs are unclear. In the current study, we visualized the epithelia in the developing cloaca and nephric ducts (NDs). Systemic stereoscopic analyses revealed that the ND-cloaca connection sites shifted from the lateral-middle to dorsal-anterior part of the cloaca during cloacal division from E10.5 to E11.5 in mouse embryos. Genetic cell labeling analyses revealed that the cells in the ventral cloacal epithelium in the early stages rarely contributed to the dorsal part. Moreover, we revealed the possible morphogenetic movement of endodermal cells within the anterior part of the urogenital sinus and hindgut. These results provide the basis for understanding both cloacal development and the ARM pathogenesis. PMID:26354024

    A 2-day-old male infant, born of a non-consanguineous marriage and uneventful pregnancy was found to have anomalies of vertebral, anal, cardiac, tracheo-esophageal, radial and limb (VACTERL) association. The striking feature was the simultaneous occurrence of two rare limb defects of right upper and lower limb in the baby who also had imperforate anus and ventricular septal defect. These limb defects were-meromelia of the right upper limb (due to transverse deficiency of right humerus and absence of all the bony elements distally), and a short right lower limb due to co-existence of proximal femoral hypoplasia and fibular hemimelia. We could not trace the co-existence of these rare skeletal defects in any case with VACTERL association in the existing English literature, as was observed by us. The simultaneous occurrence of the defects involving distant anatomic sites supports the hypothesis of 'axial mesodermal dysplasia' in our patient, rather than 'caudal regression syndrome', as is popularly held in patients with anorectal malformation (ARM). Further, it points to occurrence of an early embryonic insult, probably taking place at blastogenic stage, when the developing embryo can be considered a polytopic development field. However, in absence of antenatal history suggestive of exposure to a known teratogen and a chromosomal analysis, it appears that the spectrum of anomalies in this neonate might have resulted secondary to early amniotic leak and temporary oligohydramnios.

    Anorectal disorders such as dyssynergic defecation, fecal incontinence, levator ani syndrome and solitary rectal ulcer syndrome are common, and affect both the adult and pediatric populations. Although they are treated with several treatment approaches, over the last two decades, biofeedback therapy using visual and verbal feedback techniques has emerged as an useful option. Because it is safe, it is commonly recommended. However, the clinical efficacy of biofeedback therapy in adults and children is not clearly known, and there is a lack of critical appraisal of the techniques used and the outcomes of biofeedback therapy for these disorders. The American Neurogastroenterology and Motility Society and the European Society of Neurogastroenterology and Motility convened a task force to examine the indications, study performance characteristics, methodologies used and the efficacy of biofeedback therapy, and to provide evidence-based recommendations. Based on the strength of evidence, biofeedback therapy is recommended for the short term and long term treatment of constipation with dyssynergic defecation (Level I, Grade A), and for the treatment of fecal incontinence (Level II, Grade B). Biofeedback therapy may be useful in the short-term treatment of Levator Ani Syndrome with dyssynergic defecation (Level II, Grade B), and solitary rectal ulcer syndrome with dyssynergic defecation (Level III, Grade C), but the evidence is fair. Evidence does not support the use of biofeedback for the treatment of childhood constipation (Level 1, Grade D). PMID:25828100

    Glucose control and weight loss are cornerstones of type 2 diabetes treatment. Currently, only glucagon-like peptide-1 (GLP1) analogs are able to achieve both weight loss and glucose tolerance. Both glucose and body weight are regulated by the brain, which contains GLP1 receptors (GLP1R). Even though the brain is poised to mediate the effects of GLP1 analogs, it remains unclear whether the glucose- and body weight–lowering effects of long-acting GLP1R agonists are via direct action on CNS GLP1R or the result of downstream activation of afferent neuronal GLP1R. We generated mice with either neuronal or visceral nerve-specific deletion of Glp1r and then administered liraglutide, a long-acting GLP1R agonist. We found that neither reduction of GLP1R in the CNS nor in the visceral nerves resulted in alterations in body weight or food intake in animals fed normal chow or a high-fat diet. Liraglutide treatment provided beneficial glucose-lowering effects in both chow- and high-fat–fed mice lacking GLP1R in the CNS or visceral nerves; however, liraglutide was ineffective at altering food intake, body weight, or causing a conditioned taste aversion in mice lacking neuronal GLP1R. These data indicate that neuronal GLP1Rs mediate body weight and anorectic effects of liraglutide, but are not required for glucose-lowering effects. PMID:24762441

    Dyssynergic defecation is a common health problem affecting the quality of life of patients adversely. We aimed to evaluate the impact of biofeedback therapy on the quality of life of constipated patients due to dyssynergic defecation. Constipated patients due to dyssynergic defecation were enrolled to the study. Patients having secondary causes of constipation and who didn't fulfill the eligible criteria were excluded. All the patients underwent three to ten sessions each of which was thirty minutes biofeedback therapy under the supervision of a trained nurse. After one month the patients were assessed for the control. The impact of biofeedback therapy on the quality of life of patients having dyssynergic defecation was assessed using the validated Medical Outcomes Study Short Form-36 (SF-36) questionnaire before and one month after therapy. Thirty-two patients (20 female 62.5%, 12 male 37.5% and mean age 48 (18-72) underwent three to ten sessions biofeedback therapy. Post-therapy improvements of subscores of SF-36 consists of eight domains were all statistically significant when we compared with the pre-therapy values. This study showed not only the effectiveness of biofeedback as a therapy modality for constipation but also its impact on the improvement of QOL of constipated patients due to dyssynergic defecation. Patients with chronic constipation not improved by dietary fiber and laxatives should be referred to specialized centers that have facilities for further anorectal physiological assessments.

  1. GPR30 mediates anorectic estrogen-induced STAT3 signaling in the hypothalamus.

    Estrogen plays an important role in the control of energy balance in the hypothalamus. Leptin-independent STAT3 activation (i.e., tyrosine(705)-phosphorylation of STAT3, pSTAT3) in the hypothalamus is hypothesized as the primary mechanism of the estrogen-induced anorexic response. However, the type of estrogen receptor that mediates this regulation is unknown. We investigated the role of the G protein-coupled receptor 30 (GPR30) in estradiol (E2)-induced STAT3 activation in the hypothalamus. Regulation of STAT3 activation by E2, G-1, a specific agonist of GPR30 and G-15, a specific antagonist of GPR30 was analyzed in vitro and in vivo. Effect of GPR30 activation on eating behavior was analyzed in vivo. E2 stimulated pSTAT3 in cells expressing GPR30, but not expressing estrogen receptor ERα and ERβ. G-1 induced pSTAT3, and G-15 inhibited E2-induced pSTAT3 in primary cultures of hypothalamic neurons. A cerebroventricular injection of G-1 increased pSTAT3 in the arcuate nucleus of mice, which was associated with a decrease in food intake and body weight gain. These results suggest that GPR30 is the estrogen receptor that mediates the anorectic effect of estrogen through the STAT3 pathway in the hypothalamus. Copyright © 2014 Elsevier Inc.

    Anorectal malignant melanoma (ARMM) is an extremely rare condition, often misdiagnosed and mistreated until development of metastatic disease. Clinical presentation mimicking hemorrhoids is a well-known pitfall. We present a male patient with hemorrhoidal nodules who was referred to the policlinic of dermatology for management of anal pruritus. A dark macule was detected over one of the hemorrhoidal nodules histologically verified as melanoma. Subsequent CT and PET/CT showed lymph nodes involvement and the patient underwent wide local excision (WSE) followed by abdominoperineal resection (APR). The rarity of ARMM does not allow for establishment of a validated staging system, placebo-controlled treatment trials and management guidelines adoption. The current treatment for the condition is surgical excision, using different techniques according to the stage of the disease and depth of invasion. The prognosis and overall survival are poor, but recent genetic studies give promising results for molecular targeting. Awareness for this disease is indispensable, as early recognition could result in improved survival and quality of life.

    Rotaviruses and other enteropathogenic agents were detected in 288 (42.1%) of 684 children in day care centers of Instituto Politecnico Nacional in Mexico City. The same agents were also found in 114 (37.7%) of 302 adults directly involved in the care of the children. The study was carried out from July to December 1982 and from July 1983 to February 1984. Rotaviruses were the main enteropathogenic agents found and were detected in 169 (29.9%) of 564 children without diarrhea and in 34 (28.3%) of 120 children with diarrhea. These viruses were present in 62 (20.5%) of 302 adults without diarrhea. Of all rotavirus-positive individuals, 20% were also positive for other enteropathogens. All these observations indicate that asymptomatic rotavirus infections are not a rare event in children and that diarrhea caused by rotavirus infections is only one of the expressions of their presence.

    Three-quarters of the estimated 390 million dengue virus (DENV) infections each year are clinically inapparent. People with inapparent dengue virus infections are generally considered dead-end hosts for transmission because they do not reach sufficiently high viremia levels to infect mosquitoes. Here, we show that, despite their lower average level of viremia, asymptomatic people can be infectious to mosquitoes. Moreover, at a given level of viremia, DENV-infected people with no detectable symptoms or before the onset of symptoms are significantly more infectious to mosquitoes than people with symptomatic infections. Because DENV viremic people without clinical symptoms may be exposed to more mosquitoes through their undisrupted daily routines than sick people and represent the bulk of DENV infections, our data indicate that they have the potential to contribute significantly more to virus transmission to mosquitoes than previously recognized.

    This cross-sectional study was undertaken to determine the prevalence of asymptomatic bacteriuria (ASB), the commonest bacterial isolates and the antibiotic sensitivity pattern among 556 pregnant women in Lagos University Teaching Hospital (LUTH), Nigeria. Women with a bacterial count over 100,000 colony-forming units per millilitre of the same organisms in paired urine samples were considered to have ASB. The prevalence of ASB was 14.6%. Klebsiella was the commonest micro-organism (39.2%) isolated. ASB was significantly associated with marital status, body mass index and parity. There was a significant relationship between urinary nitrites and ASB. The isolated organisms showed remarkable resistance to commonly prescribed antibiotics such as amoxicillin, cloxacillin and trimethoprim but good sensitivity to ofloxacin, gentamycin and ceftazidime. These facts have implications for the management of ASB in pregnancy.

    Human microsporidiosis, a serious disease of immunocompetent and immunosuppressed people, can be due to zoonotic transmission of microsporidian spores. A survey utilizing chromotrope 2R stain and fluorescent in situ hybridization techniques for testing feces from 193 captive mammals demonstrated that 3 animals (1.6%) shed Encephalitozoon bieneusi spores. These include two critically endangered species (i.e., black lemurs, Eulemur macaco flavifrons; and Visayan warty pig, Sus cebifrons negrinus) and a threatened species (mongoose lemur, Eulemur mongoz). The concentration of spores varied from 2.7 x 10(5) to 5.7 x 10(5)/g of feces, and all infections were asymptomatic. The study demonstrates that E. bieneusi spores can originate from captive animals, which is of particular epidemiologic importance because the close containment of zoological gardens can facilitate pathogen spread to other animals and also to people such as zoo personnel and visitors.

    Danon disease is a rare, codominant X-linked genetic disorder characterized by the triad of left ventricular hypertrophy, mental retardation, and peripheral myopathy. This disease is caused by mutations in the gene that encodes lysosomal associated membrane protein 2 (LAMP2), a deficiency of which results in the accumulation of autophagic granular débris within the vacuoles of muscle cells. This is a report of an asymptomatic 19-year-old man with Danon disease in the absence of mental retardation or clinically significant skeletal myopathy. This case underscores the importance of accurate diagnosis of unexplained left ventricular hypertrophy, in order to establish an appropriate treatment plan and to advise genetic counseling.

    A 78-year-old asymptomatic woman was referred to our clinic for a second opinion regarding indication for mitral valve surgery. An echocardiogram showed a moderate mitral stenosis with a concomitant severe regurgitation. The most striking feature, however, was a giant left atrium with a parasternal anteroposterior diameter of 79 mm and a left atrial volume index of 364 mL/m². There are various echocardiographic definitions of a giant left atrium, which are mainly based on measurements of the anteroposterior diameter of the left atrium using M-mode in the parasternal long axis view. Since the commonly accepted method for echocardiographic evaluation of left atrial size is left atrial volume index, we propose a cut-off value of 140 mL/m2 for the definition of a “giant left atrium”.

    In this article, we present the case of a 52-year-old male with a history of parotid carcinosarcoma with initial diagnosis being 18 months prior. Initial treatment included a combination of gamma knife surgery coupled with high dosage chemotherapy and X-ray radiation therapy. At the time of follow-up, the patient presented with no complaints and had a nearly normal physical exam with the exception of some facial nerve weakness on the same side as the initial surgery. Despite being asymptomatic, the patient had a significant progression of disease that was manifested with intracranial lesions, multiple pathologic fractures, and a dramatic increase in overall tumor burden. Ultimately, the patient decided to pursue comfort measures only and succumbed to the disease peacefully soon thereafter. PMID:27847832

    Overtreatment of asymptomatic bacteriuria (ASB) is widespread and may result in antibiotic side-effects, excess costs to the healthcare system, and may potentially trigger antimicrobial resistance. According to international management guidelines, ASB is not an indication for antibiotic treatment (with few exceptions). To determine reasons for using antibiotics to treat ASB in the absence of a treatment indication. A qualitative study was conducted at a tertiary care hospital in Switzerland during 2011. We interviewed 21 internal medicine residents and attending physicians selected by purposive sampling, using a semi-structured questionnaire. Responses were analysed in an inductive thematic content approach using dedicated software (MAXQDA(®)). In the 21 interviews, the following thematic rationales for antibiotic overtreatment of ASB were reported (in order of reporting frequency): (i) treating laboratory findings without taking the clinical picture into account (N = 17); (ii) psychological factors such as anxiety, overcautiousness, or anticipated positive impact on patient outcomes (N = 13); (iii) external pressors such as institutional culture, peer pressure, patient expectation, and excessive workload that interferes with proper decision-making (N = 9); (iv) difficulty with interpreting clinical signs and symptoms (N = 8). In this qualitative study we identified both physician-centred factors (e.g. overcautiousness) and external pressors (e.g. excessive workload) as motivators for prescribing unnecessary antibiotics. Also, we interpreted the frequently cited practice of treating asymptomatic patients based on laboratory findings alone as lack of awareness of evidence-based best practices.

  12. Compulsory sexuality.

    PubMed

    Emens, Elizabeth F

    2014-02-01

    Asexuality is an emerging identity category that challenges the common assumption that everyone is defined by some type of sexual attraction. Asexuals--those who report feeling no sexual attraction to others--constitute one percent of the population, according to one prominent study. In recent years, some individuals have begun to identify as asexual and to connect around their experiences interacting with a sexual society. Asexuality has also become a protected classification under the antidiscrimination law of one state and several localities, but legal scholarship has thus far neglected the subject. This Article introduces asexuality to the legal literature as a category of analysis, an object of empirical study, and a phenomenon of medical science. It then offers a close examination of the growing community of self-identified asexuals. Asexual identity has revealing intersections with the more familiar categories of gender, sexual orientation, and disability, and inspires new models for understanding sexuality. Thinking about asexuality also sheds light on our legal system. Ours is arguably a sexual law, predicated on the assumption that sex is important. This Article uses asexuality to develop a framework for identifying the ways that law privileges sexuality. Across various fields, these interactions include legal requirements of sexual activity, special carve-outs to shield sexuality from law, legal protections from others' sexuality, and legal protections for sexual identity. Applying this framework, the Article traces several ways that our sexual law burdens, and occasionally benefits, asexuals. This Article concludes by closely examining asexuality's prospects for broader inclusion into federal, state, and local antidiscrimination laws.

    The potential adverse consequences, personal distress, shame and guilt presented by patients who suffer from sexual addiction require a more in-depth understanding of the phenomenology and psychobiology of this disorder. A bibliographic review was conducted using MEDLINE and EBSCO databases with the following keywords: "sexual addiction," "hypersexuality," "compulsive sexual behavior," "behavioural addiction," "treatment," and "addiction." Several conceptualizations of excessive nonparaphilic sexual disorder have been proposed based on the models of, respectively, obsessive compulsive disorder, impulse control disorder, out of control excessive sexual disorder, and addictive disorder. Despite the lack of robust scientific data, a number of clinical elements, such as the frequent preoccupation with this type of behavior, the time spent in sexual activities, the continuation of this behavior despite its negative consequences, the repeated and unsuccessful efforts made to reduce the behavior, are in favor of an addictive disorder. In addition there is a high comorbidity between excessive sexual behavior and other addictive behaviors. The phenomenology of excessive nonparaphilic sexual disorder favors its conceptualization as an addictive behavior, rather than an obsessive-compulsive, or an impulse control disorder. Moreover, the criteria that are quite close to those of addictive disorders were recently proposed for the future DSM-V in order to improve the characterization of this condition. Finally, controlled studies are warranted in order to establish clear guidelines for treatment of sexual addiction.

    The term “internet sexuality” (or OSA, online sexual activities) refers to sexual-related content and activities observable on the internet (cf. Adams, Oye, & Parker, 2003; Cooper, McLoughlin, & Campbell, 2000; Leiblum & Döring, 2002). It designates a variety of sexual phenomena (e.g., pornography, sex education, sexual contacts) related to a wide spectrum of online services and applications (e.g., websites, online chat rooms, peer-to-peer networks). If an even broader range of computer networks - such as the Usenet or bulletin board systems - is included in this extensional definition, one speaks of “online sexuality” or “cybersexuality.”

    It should be recognized that sexuality in the aging male is of such import that a complete sexual history must be performed. By taking a complete sexual history, facts can be obtained that will allow for appropriate focus relating to a holistic evaluation and will enable us to dispel antiquated sexual myths pertaining to the aging male. If initiated by the history taker, questions concerning sexuality may be discussed more comfortably by the patient. Erectile dysfunction, male sexual response cycle, testosterone, sexually transmitted diseases, human immunodeficiency virus, long-term illness, along with religion and culture are explored in this article with the aim of improving one's knowledge base, self reflection, and awareness of the importance of male sexuality. A complete understanding and appreciation of the aging male's medical history, surgical history, social history, and emotional history as well as his sexual, cultural, and religious concepts will allow the health care provider to better analyze information, and to recommend and provide appropriate advice and treatment to the aging male patient.

    Estimates are that one in four women will be sexually assaulted at some time during her life. For the victim, it is a life-changing, traumatic event. This paper reviews both the immediate and long-term care of the sexual assault victim. For the victim seen immediately after the assault, physicians must provide empathic, nonjudgmental care that puts the victim back in control of her life. It is essential that the physician provide continued support for the victim and her family through the recovery process. The medical presentations that should prompt the physician to inquire about undisclosed sexual assault and the social and cultural myths that promote sexual assault are reviewed.

    Sexual pain is an underrecognized and poorly treated constellation of disorders that significantly impact affected women and their partners. Recognized as a form of chronic pain, sexual pain disorders are heterogeneous and include dyspareunia (superficial and deep), vaginismus, vulvodynia, vestibulitis, and noncoital sexual pain disorder. Women too often tolerate pain in the belief that this will meet their partners' needs. This article provides a review of the terminology and definition of the condition, theories on the pathophysiology, diagnostic considerations, and recommendations on the management of female sexual pain.

    The consequences of adolescent sexual behavior are an enormous burden both for the adolescent and society. The problem is not that teens are sexually active but rather that they have little preparation and guidance in developing responsible sexual behavior. Developmentally, adolescents reach physical maturity before they are cognitively able to appreciate the consequences of their behavior. A teenager's primary source of information regarding sexuality is his or her peer group, all of whom are experiencing and reinforcing the same behaviors. The family, the major socializer of other behaviors, is not as powerful a force in shaping responsible sexual behavior because of parental discomfort with sex education and sexual discussions. This is the result of a social milieu in which sex is frequently portrayed but rarely linked with responsible behavior or accurate, nonjudgmental information. The pediatric practitioner is in an ideal position to intervene in these dynamics. In the office, the practitioner can provide accurate sexual information to both parents and adolescents, support parental-child communication on sexual issues, and provide appropriate services or referral. In the community, the practitioner can advocate for school-based sex education as well as act as an information resource. Finally, the practitioner can advocate for the health care needs for adolescents on a national level, supporting legislation that provides adolescents with information and access to services necessary to make responsible sexual decisions.

Cross-sectional study. Departments of obstetrics and gynecology in three different Swedish hospitals. Fifty-eight women meeting strict criteria for PMDD, a control group of 102 women seeking care at the gynecological outpatient clinic (ObGyn controls) and 47 asymptomatic healthy control subjects were included in this study. The Swedish version of the Abuse Assessment Screen was used to collect information on physical and sexual abuse, and the screening instrument was administered as a face-to-face interview. Previous and ongoing physical and sexual abuse. Any lifetime abuse (physical, emotional or sexual) was reported by 31.0% of PMDD patients, by 39.2% of ObGyn controls and by 21.3% of healthy controls. The ObGyn controls reported physical and/or emotional abuse significantly more often than PMDD patients as well as healthy controls (p<0.05). Lifetime sexual abuse was reported significantly more often by ObGyn controls than by healthy controls (p<0.05). Patients with PMDD appear not to have suffered physical, emotional or sexual abuse to a greater extent than other gynecological patients or healthy control subjects. However, exposure to violence was common in all groups of interviewed women, and for the individual patient these experiences may contribute to their experience of symptoms. © 2011 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2011 Nordic Federation of Societies of Obstetrics and Gynecology.

  1. Asymptomatic bacteriuria and symptomatic urinary tract infections in pregnancy.

    Symptomatic and asymptomatic bacteriuria is common in pregnant women. A history of previous urinary tract infections and low socioeconomic status are risk factors for bacteriuria in pregnancy. Escherichia coli is the most common aetiologic agent in both symptomatic and asymptomatic infection and quantitative culture is the gold standard for diagnosis. Treatment of asymptomatic bacteriuria has been shown to reduce the rate of pyelonephritis in pregnancy and therefore screening for and treatment of asymptomatic bacteriuria has become a standard of obstetrical care. Antibiotic treatment of asymptomatic bacteriuria is associated with a decrease in the incidence of low birth weight, but the methodological quality of the studies limits the strength of the conclusions that can be drawn. Debate exists in the literature as to whether treated pyelonephritis is associated with adverse fetal outcomes. There is no clear consensus in the literature on antibiotic choice or duration of therapy for infection. With increasing antibiotic resistance, consideration of local resistance rates is necessary when choosing therapy.

    Despite shifts toward greater acceptance in U.S. public opinion and policy, lesbian, gay, and bisexual people remain widely stigmatized. This article reviews empirical research on sexual prejudice, that is, heterosexuals' internalization of cultural stigma, manifested in the form of negative attitudes toward sexual minorities and same-sex desires and behaviors. After briefly reviewing measurement issues, we discuss linkages between sexual prejudice and religion, gender, sexuality, and related variables, and consider how the cultural institutions encompassing these domains create a social context within which individual expressions of prejudice can meet important psychological needs. These include needs for securing social acceptance, affirming values that are central to one's self-concept, and avoiding anxiety and other negative emotions associated with threats to self-esteem. We conclude by discussing factors that may motivate heterosexuals to reduce their own sexual prejudice, including intergroup contact, as well as avenues for future empirical inquiry.

    To investigate the hypothesis that pelvic floor disorders are associated with female sexual problems, independently of other related factors. The study population included 301 adult women seeking outpatient gynecologic and urogynecologic care. Pelvic floor disorders were assessed with the Pelvic Floor Disorders Inventory-20 (PFDI-20) and the pelvic organ prolapse quantification examination. Sexual function was assessed with the Personal Experiences Questionnaire. Using ordinal regression analysis, we identified characteristics and conditions associated with decreased libido, infrequent orgasm, decreased arousal, and dyspareunia. Sexual function was poorer among 78 women (26%) without a current sexual partner than among 223 with a partner (P<.01). Among the 223 with a current partner, women with a high Pelvic Floor Disorders Inventory score were significantly more likely to report decreased arousal (P<.01), infrequent orgasm (P<.01), and increased dyspareunia (P<.01). A similar pattern was observed for the urinary, colorectal-anal, and prolapse scales of the Pelvic Floor Disorders Inventory, although some associations were marginally significant. Stage III-IV prolapse was significantly associated with infrequent orgasm (P=.02), but other sexual complaints were not more common with increasing prolapse stage. Pelvic floor symptoms are significantly associated with reduced sexual arousal, infrequent orgasm, and dyspareunia. We conclude that sexual function is worse in women with symptomatic prolapse but not in women with asymptomatic prolapse. II.

    Combined tests of anorectal manometry, sphincter electromyography and rectal sensation were carried out in 302 patients with faecal incontinence (235 women, 67 men). The results obtained were compared with 65 normal subjects (35 women, 30 men). A mechanism for incontinence was identified in all and the majority of patients had more than one abnormality. Two hundred and seventy eight patients (92%) had a weak external anal sphincter, 185 of these (67%, mostly women) also showed abnormal perineal descent, and 14 women showed clinical evidence of sphincter damage as a result of obstetric trauma. Ten per cent of patients with impaired external anal sphincter contraction showed associated evidence of spinal disease (impaired rectal sensation plus attenuated or enhanced reflex external anal sphincter activity). Unlike the other groups, the 'spinal' group contained equal numbers of men and women. Ninety seven patients (32%) had evidence of a weak internal anal sphincter. The external sphincter was also very weak and 92% of these patients also had perineal descent. Eighty two patients (27%) showed an unstable internal sphincter, characterised by prolonged 'spontaneous' anal relaxation under resting conditions and an abnormal reduction in anal pressure after conscious contraction of the sphincter or an increase in intraabdominal pressure. One hundred and forty two patients (47%) had a hypersensitive rectum associated with enhanced anorectal responses to rectal distension. All these patients had an abnormally weak external sphincter, suggesting that the hypersensitive or 'irritable' rectum should not be regarded as a cause of faecal incontinence unless accompanied by external sphincter weakness. Twenty four patients (8%) showed a normal basal and squeeze pressures and impaired rectal sensation; six showed giant rectal contractions during rectal distension. The results show that idiopathic faecal incontinence is not caused by a single abnormality, and it is suggested that

    Obesity is a leading public health problem worldwide. Multiple lines of evidence associate deficits in the brain reward circuit with obesity. Whether alterations in brain reward sensitivity precede or are a consequence of obesity is unknown. This study aimed to investigate both innate and obesity-induced differences in the sensitivity to the effects of an indirect dopaminergic agonist. Rats genetically prone to diet-induced obesity (DIO) and their counterpart diet-resistant (DR) were fed a chow diet, and their response to D-amphetamine on intracranial self-stimulation and food intake were assessed. The same variables were then evaluated after exposing the rats to a high-fat diet, after DIO rats selectively developed obesity. Finally, gene expression levels of dopamine receptors 1 and 2 as well as tyrosine hydroxylase were measured in reward-related brain regions. In a pre-obesity state, DIO rats showed innate decreased sensitivity to the reward-enhancing and anorectic effects of D-amphetamine, as compared to DR rats. In a diet-induced obese state, the insensitivity to the potentiating effects of D-amphetamine on intracranial self-stimulation (ICSS) threshold persisted and became more marked in DIO rats, while the anorectic effects were comparable between genotypes. Finally, innate and obesity-induced differences in the gene expression of dopamine receptors were observed. Our results demonstrate that brain reward deficits antedate the development of obesity and worsen after obesity is fully developed, suggesting that these alterations represent vulnerability factors for its development. Moreover, our data suggests that the reward-enhancing and anorectic effects of D-amphetamine are dissociable in the context of obesity.

  8. Consumption of palatable food decreases the anorectic effects of serotonergic, but not dopaminergic drugs in baboons.

    We examined the effects of periodic access to a palatable, high sugar content food (candy) in 8 male baboons on the anorectic response to d-amphetamine, which increases dopamine, and dexfenfluramine, which increases serotonin. During candy access, up to 200 candies containing 75% of energy as sugar were available during the morning on Mondays, Wednesdays and Fridays; food pellets (19% of energy as sugar) were available in the afternoon and throughout the remaining days of the week. During candy access, baboons consumed a mean of 177 pieces of candy containing 696 kcal (2.91 MJ) in the morning compared to 44 food pellets and 150 kcal (0.63 MJ) in the morning on non-candy days. Food pellet intake was lower during candy access. Complete dose-response functions for the effects of the drugs on food pellet intake on days that candy was not available were determined before, during, and after the period of access to candy. Dexfenfluramine and amphetamine produced dose-dependent decreases in food pellet intake and increases in latency to eat food pellets before, during, and after candy access. During access to candy, the dose-response function for dexfenfluramine was shifted to the right indicating the development of tolerance, while that for amphetamine was shifted to the left indicating sensitization. Only the dose-response function for dexfenfluramine returned to baseline after candy access suggesting that the difference was specific to concurrent palatable food consumption. We hypothesize that tolerance to the effects of dexfenfluramine reflects a decrease in the satiating effect of serotonin release due to repeatedly eating large amounts of palatable food.

    Desire to defecate is associated with a unique anal contractile response, the sensorimotor response (SMR). However, the precise muscle(s) involved is not known. We aimed to examine the role of external and internal anal sphincter and the puborectalis muscle in the genesis of SMR. Anorectal 3-D pressure topography was performed in 10 healthy subjects during graded rectal balloon distention using a novel high-definition manometry system consisting of a probe with 256 pressure sensors arranged circumferentially. The anal pressure changes before, during, and after the onset of SMR were measured at every millimeter along the length of anal canal and in 3-D by dividing the anal canal into 4 × 2.1-mm grids. Pressures were assessed in the longitudinal and anterior-posterior axis. Anal ultrasound was performed to assess puborectalis morphology. 3-D topography demonstrated that rectal distention produced an SMR coinciding with desire to defecate and predominantly induced by contraction of puborectalis. Anal ultrasound showed that the puborectalis was located at mean distance of 3.5 cm from anal verge, which corresponded with peak pressure difference between the anterior and posterior vectors observed at 3.4 cm with 3-D topography (r = 0.77). The highest absolute and percentage increases in pressure during SMR were seen in the superior-posterior portion of anal canal, reaffirming the role of puborectalis. The SMR anal pressure profile showed a peak pressure at 1.6 cm from anal verge in the anterior and posterior vectors and distinct increase in pressure only posteriorly at 3.2 cm corresponding to puborectalis. We concluded that SMR is primarily induced by the activation and contraction of the puborectalis muscle in response to a sensation of a desire to defecate. PMID:21109594

    To determine the prevalence of congenital heart defects (CHDs) in patients with mild or severe congenital anorectal malformations (CARMs), and whether all patients with CARM need pediatric cardiology screening. We included 129 patients with CARM born between 2004 and 2013, and referred to University Medical Center Groningen. Recto-perineal and recto-vestibular fistulas were classified as mild CARMs, all others as severe. Significant patent foramen ovale, secundum atrial septal defect, and small ventricular septum defect were classified as minor CHDs, all others as major. Of 129 patients with CARM, 67% had mild CARM, 33% severe CARM, and 17% were additionally diagnosed with CHD. CHDs were distributed equally in patients with mild or severe CARMs. Patients with multiple congenital abnormalities were more frequently diagnosed with CHD (n = 16, 36%) than patients without multiple congenital malformations (n = 5, 9%, P = .001). Patients with CARM diagnosed with CHD using pediatric cardiac echo screening were younger than 3 months of age at diagnosis. Earlier general pediatric examinations missed 7 (50%) children with mild and 4 (50%) with severe CHDs. The severity of CARM could predict neither prevalence nor severity of CHD. More than one-half of CHDs were missed during the first physical examination. No new CHDs were found in patients older than 3 months of age at the time CARMs were diagnosed. We recommend screening all patients with CARM younger than 3 months of age for CHD at the time CARM is diagnosed. Preoperative echocardiography should be the rule in children younger than 3 months of age and with multiple congenital anomalies. Copyright © 2016 Elsevier Inc. All rights reserved.

    The aim was to describe the frequency of lower urinary tract symptoms (LUTS) in children with anorectal malformations with rectoperineal fistulas (ARM-P), as compared with healthy controls based on gender. LUTS were defined using the 2014 definitions of the International Children's Continence Society. Data were collected at 2 tertiary pediatric surgery centers in 2 countries from all children aged 4-12years who had undergone an operation for ARM-P. A total of 24 girls and 33 boys, with a median age of 8 (4-12)years, were eligible and compared with 165 controls. Of the patient group, 4 (17%) girls had 8 urinary tract anomalies (UTA), and 8 (24%) boys had 13 UTA. There were no gender differences in LUTS among the patients. The frequency of urinary tract infections was higher among the patients (5/24 girls and 7/55 boys) than the controls (1/55 and 4/110) (p=0.009). More patients (5/24 girls and 5/33 boys) than controls (1/55 and 2/110) used daily urinary medications (p=0.009 and p=0.007, respectively). Patients with UTA reported urinary infections more frequently (3/4 girls and 4/8 boys) than those without UTA (2/20 girls and 0/25 boys) (p=0.018 and p=0.002, respectively). Children with ARM-P had more LUTS than controls, and patients with concomitant UTA had more LUTS than patients without UTA. Therefore, children with ARM-P are suggested to have routine follow-up for both UTA and LUTS. Copyright © 2016 Elsevier Inc. All rights reserved.

    Purpose: To delineate the individual pelvic floor muscles considered to be involved in anorectal toxicity and to investigate dose-effect relationships for fecal incontinence-related complaints after prostate radiotherapy (RT). Methods and Materials: In 48 patients treated for localized prostate cancer, the internal anal sphincter (IAS) muscle, the external anal sphincter (EAS) muscle, the puborectalis muscle (PRM), and the levator ani muscles (LAM) in addition to the anal wall (Awall) and rectal wall (Rwall) were retrospectively delineated on planning computed tomography scans. Dose parameters were obtained and compared between patients with and without fecal urgency, incontinence, and frequency. Dose-effect curves were constructed. Finally, the effect of an endorectal balloon, which was applied in 28 patients, was investigated. Results: The total volume of the pelvic floor muscles together was about three times that of the Awall. The PRM was exposed to the highest RT dose, whereas the EAS received the lowest dose. Several anal and rectal dose parameters, as well as doses to all separate pelvic floor muscles, were associated with urgency, while incontinence was associated mainly with doses to the EAS and PRM. Based on the dose-effect curves, the following constraints regarding mean doses could be deduced to reduce the risk of urgency: {<=}30 Gy to the IAS; {<=}10 Gy to the EAS; {<=}50 Gy to the PRM; and {<=}40 Gy to the LAM. No dose-effect relationships for frequency were observed. Patients treated with an endorectal balloon reported significantly less urgency and incontinence, while their treatment plans showed significantly lower doses to the Awall, Rwall, and all pelvic floor muscles. Conclusions: Incontinence-related complaints show specific dose-effect relationships to individual pelvic floor muscles. Dose constraints for each muscle can be identified for RT planning. When only the Awall is delineated, substantial components of the continence apparatus are

    Genital and anorectal mucosal melanomas (GAMMs) are rare compared with cutaneous melanoma (CM). Many epidemiological and genetic studies have been carried out on CM. In contrast, the genetic and environmental risk factors for GAMM have been poorly documented up to now. To compare the distribution of pigmentation and naevus phenotypes, sun exposure and family history of melanoma between patients with GAMM and CM. We compared two series of patients, 81 with GAMM and 293 with CM. Patients with GAMM and CM did not show significant differences for phenotypic risk factors. However, patients with GAMM tended to display red hair (11% vs. 5·5%, P = 0·08) and a poor tanning ability (22% vs. 13·3%, P = 0·06) at a higher frequency than patients with CM. A family history of melanoma was significantly more frequent with GAMM than with CM (18% vs. 7·5%, P = 0·005). Apart from the GAMM index case, affected relatives had CM except in one family. The frequency of multiple primary melanomas (MPMs) was similar in the GAMM and CM series (6% vs. 5·3%, P = 0·43). All patients with GAMM and MPM had only one GAMM primary, while the other primary was cutaneous. No CDKN2A germline mutation was detected in patients with GAMM. This study shows that GAMM and CM may occur in the same patient, and GAMM may develop in a familial setting. The association of both GAMM and CM in patients and families suggests shared genetic factors by these two types of melanoma. © 2013 British Association of Dermatologists.

    The now-banned anorectic molecule, dexfenfluramine, promotes serotonin release through a serotonin transporter-dependent mechanism, and it has been widely prescribed for the treatment of obesity. Previous studies have identified that 5-HT2B receptors have important roles in dexfenfluramine side effects, that is, pulmonary hypertension, plasma serotonin level regulation, and valvulopathy. We thus investigated a putative contribution of 5-HT2B receptors in dexfenfluramine-dependent feeding behavior in mice. Interestingly, the hypophagic response to dexfenfluramine (3–10 mg/kg) observed in wild-type mice (1–4 h) was eliminated in mice lacking 5-HT2B receptors (5-HT2B−/−). These findings were further validated by the lack of hypophagic response to dexfenfluramine in wild-type mice treated with RS127445, a highly selective and potent antagonist (pKi=8.22±0.24). Using microdialysis, we observed that in 5-HT2B−/− awake mice, the dexfenfluramine-induced hypothalamic peak of serotonin release (1 h) was strongly reduced (fourfold) compared with wild type. Moreover, using hypothalamic synaptosomes, we established the serotonergic neuron autonomous properties of this effect: a strong serotonin release was observed upon dexfenfluramine stimulation of synaptosome preparation from wild type but not from mice lacking active 5-HT2B receptors. These findings strongly suggest that activation of presynaptic 5-HT2B receptors is a limiting step in the serotonin transporter dependant-releasing effect of dexfenfluramine, whereas other serotonin receptors act downstream with respect to feeding behavior.

    We examined the effects of periodic access to a palatable, high sugar content food (candy) in 8 male baboons on the anorectic response to d-amphetamine, which increases dopamine, and dexfenfluramine, which increases serotonin. During candy access, up to 200 candies containing 75% of energy as sugar were available during the morning on Mondays, Wednesdays and Fridays; food pellets (19% of energy as sugar) were available in the afternoon and throughout the remaining days of the week. During candy access, baboons consumed a mean of 177 pieces of candy containing 696 kcal (2.91 MJ) in the morning compared to 44 food pellets and 150 kcal (0.63 MJ) in the morning on non-candy days. Food pellet intake was lower during candy access. Complete dose-response functions for the effects of the drugs on food pellet intake on days that candy was not available were determined before, during, and after the period of access to candy. Dexfenfluramine and amphetamine produced dose-dependent decreases in food pellet intake and increases in latency to eat food pellets before, during, and after candy access. During access to candy, the dose-response function for dexfenfluramine was shifted to the right indicating the development of tolerance, while that for amphetamine was shifted to the left indicating sensitization. Only the dose-response function for dexfenfluramine returned to baseline after candy access suggesting that the difference was specific to concurrent palatable food consumption. We hypothesize that tolerance to the effects of dexfenfluramine reflects a decrease in the satiating effect of serotonin release due to repeatedly eating large amounts of palatable food.

    The surgical correction of anorectal malformations remains a serious problem despite their relatively frequent occurrence. Our surgical experience with 90 patients, seen in the past ten years, includes abdominal-perineal or sacro-abdominal-perineal repair in 28 patients, complete perineal anoplasty in 13 patients, and “cut-back” perineal anoplasty in 38 patients. Secondary surgical procedures for “fecal reservoir syndrome” (seven patients), revision for stricture (11 patients) and excision of redundant mucous membrane (ten patients). The observations made from this clinical study are: 1) The importance of thorough urological and neurological evaluation of “high” abnormalities and the value of the cremasteric and bulbocavernosus reflexes as indicators of sacral innervation. 2) Increasing satisfaction with the “cut-back” anoplasty as a definitive procedure or as a temporary stage in low recto-vaginal or recto-vestibular fistulas. The technique for the “cut-back” is improved by the use of Burow's triangles and the use of nonabsorbable sutures. 3) The advisability of the complete perineal anoplasty with posterior positioning of the anus and construction of a perineal body in patients with low recto-vaginal and recto-vestibular fistulas. 4) A concern over the functional capacity of the distal bowel segment in high abnormalities. This is emphasized by the experience with six secondary resections of the rectosigmoid or left colon for “fecal reservoir syndrome.” 5) Heartening results with secondary operations for stricture and redundant mucous membrane which suggest the desirability of an earlier surgical approach to these complications.

    Introduction: Management guidelines were created to screen and manage asymptomatic renal stones in U.S. astronauts. The risks for renal stone formation in astronauts due to bone loss and hypercalcuria are unknown. Astronauts have a stone risk which is about the same as commercial aviation pilots, which is about half that of the general population. However, proper management of this condition is still crucial to mitigate health and mission risks in the spaceflight environment. Methods: An extensive review of the literature and current aeromedical standards for the monitoring and management of renal stones was done. The NASA Flight Medicine Clinic's electronic medical record and Longitudinal Survey of Astronaut Health were also reviewed. Using this work, a screening and management algorithm was created that takes into consideration the unique operational environment of spaceflight. Results: Renal stone screening and management guidelines for astronauts were created based on accepted standards of care, with consideration to the environment of spaceflight. In the proposed algorithm, all astronauts will receive a yearly screening ultrasound for renal calcifications, or mineralized renal material (MRM). Any areas of MRM, 3 millimeters or larger, are considered a positive finding. Three millimeters approaches the detection limit of standard ultrasound, and several studies have shown that any stone that is 3 millimeters or less has an approximately 95 percent chance of spontaneous passage. For mission-assigned astronauts, any positive ultrasound study is followed by low-dose renal computed tomography (CT) scan, and flexible ureteroscopy if CT is positive. Other specific guidelines were also created. Discussion: The term "MRM" is used to account for small areas of calcification that may be outside the renal collecting system, and allows objectivity without otherwise constraining the diagnostic and treatment process for potentially very small calcifications of uncertain

    The aim of this report is to present a technical detail of use in the management of an anorectal malformation (ARM). A boy with ARM and a fistula to the urethra was operated on with a posterior sagittal anorectoplasty (PSARP). Before the PSARP operation, a videoendoscopy was performed through the distal stoma down to the distal end of the rectum. The rectourethral fistula was identified and a guidewire was passed through the endoscope, through the fistula, and out through the urethra. The endoscopically placed rectourethral guidewire was used as a landmark and facilitated the PSARP operation. PMID:25755952

    Little is known about anorectal function and quality of life after chemoradiation followed by local excision, which is an alternative to total mesorectal excision for selected patients with early rectal cancer. The purpose of this study was to prospectively assess anorectal function and health-related quality of life of patients with T2N0 rectal cancer who were treated with an alternative approach. This was a prospective, phase II trial. The study was multicentric (American College of Surgeons Oncology Group trial Z6041). Patients with stage cT2N0 rectal adenocarcinomas were treated with an oxaliplatin/capecitabine-based chemoradiation regimen followed by local excision. Anorectal function and quality of life were assessed at enrollment and 1 year postoperatively with the Fecal Incontinence Severity Index, Fecal Incontinence Quality of Life scale, and Functional Assessment of Cancer Therapy-Colorectal Questionnaire. Results were compared, and multivariable analysis was performed to identify predictors of outcome. Seventy-one patients (98%) were evaluated at enrollment and 66 (92%) at 1 year. Compared with baseline, no significant differences were found on Fecal Incontinence Severity Index scores at 1 year. Fecal Incontinence Quality of Life results were significantly worse in the lifestyle (p < 0.001), coping/behavior (p < 0.001), and embarrassment (p = 0.002) domains. There were no differences in the Functional Assessment of Cancer Therapy overall score, but the physical well-being subscale was significantly worse and emotional well-being was improved after surgery. Treatment with the original chemoradiation regimen predicted worse depression/self-perception and embarrassment scores in the Fecal Incontinence Quality of Life, and male sex was predictive of worse scores in the Functional Assessment of Cancer Therapy overall score and trial outcome index. Small sample size, relatively short follow-up, and absence of information before cancer diagnosis were study

    The presentation of the surgical anatomy of anorectal malformation by standard anatomical figures is not suitable for individual anorectoplasty. It is essential to understand the anatomy of the pelvic muscle (striated muscle complex: SMC) including the external anal sphincter and their three-dimensional (3D) configuration in each patient. Thus, we studied the SMC three-dimensionally with multidetector-row helical computed tomography (MRH-CT) preoperatively, and evaluated its usefulness. Fourteen patients with anorectal malformations before anorectoplasty (types: high n=6, intermediate n=2, low n=6) and two patients without anorectal malformations as controls (total: male n=8, female n=8) were investigated. An image of pelvic region was prepared with a slice thickness of 0.5 mm and a reconstruction pitch of 0.5 mm. A 3D reconstruction on a conventional personal computer (PC) was made with a volume rendering method, and assisted by our own software. The SMC was analyzed with three modified modes of 3D reconstruction corresponding to the surrounding tissues. A length of the parasagittal muscle, and both the sagittal and transverse width of the vertical fibers in the SMC at the connection to the parasagittal muscle were measured on a 3D image and then compared among three different types and controls. To eliminate variations in age, a length index was used to allow comparison. The 3D configuration of the SMC was different in every case. The arranged image mode, which displayed the SMC and the pelvic bones simultaneously, enabled to use conventional knowledge in cysto-urethrography. The length of the parasagittal muscle was longest in the high type but the width of the vertical fibers was smallest. Anatomical figures of the SMC including the external anal sphincter were clearly demonstrated on a PC in every anorectal malformation by our program. A 3D reconstruction image provides positional information on the SMC for the body surface and pelvic bone at the same time

    Catecholaminergic polymorphic ventricular tachycardia is a rare genetic disorder caused by mutations in genes involved in the intracellular calcium homeostasis of cardiac cells. Affected patients typically present with life-threatening ventricular arrhythmias precipitated by emotional/physical stress. The diagnosis is based on the demonstration of polymorphic or bidirectional ventricular tachycardia associated with adrenergic stress. Genetic testing can be confirmatory in some patients. Treatment for catecholaminergic polymorphic ventricular tachycardia includes medical and surgical efforts to suppress the effects of epinephrine at the myocardial level and/or modulation of calcium homeostasis. Mortality is high when untreated and sudden cardiac death may be the first manifestation of the disease. First-degree relatives of a proband should be offered genetic testing if the causal mutation is known. If the family mutation is not known, relatives should be clinically evaluated with provocative testing. In the absence of rigorous trials, prophylactic treatment of the asymptomatic catecholaminergic polymorphic ventricular tachycardia patient appears to reduce morbidity and mortality.

  3. Advances in the management of asymptomatic myeloma.

    Smoldering multiple myeloma (SMM) is an asymptomatic plasma cell disorder characterized by the presence of one or both features of serum M-protein at least 30 g/l and bone marrow plasma cell infiltration at least 10%. The standard of care is no treatment until symptomatic progression occurs. However, the risk of progression to active multiple myeloma is not uniform, and several markers are useful for identifying SMM patients at high risk of progression to active multiple myeloma. Overall, the presence of these factors is useful to stratify SMM patients according to their risk but the forthcoming challenge is to identify high and ultra-high-risk SMM patients because they can benefit from early treatment. A randomized trial that focused on high-risk SMM patients allocated to receive early treatment with lenalidomide plus dexamethasone vs. observation did report a significant benefit with respect to time to progression and overall survival. High-risk SMM patients should be targeted for early treatment, and more such efforts should be made to identify the ultra-high-risk subgroup within the high-risk SMM patient population which may be considered as early multiple myeloma and thereby candidates for receiving therapy before they develop myeloma-related symptomatology.

    Chlamydia trachomatis infection constitutes the most common sexual transmitted disease (STD) among young women. International studies demonstrate that prevalence changes over time and also according to places. To estimate the prevalence of this infection among asymptomatic Chilean women (15 to 24 years old) and correlating with risk factor occurrence. Transversal cohort study to identify C. trachomatis infection through a diagnostic kit designed to detect and amplify cryptic plasmid DNA by quantitative PCR from endocervical sample. 181 women were screened during the period of study. The overall prevalence estimate was 5.5% and founding significant estimate variations (0% to 14.6%) between recruiting centers. There was difference in number of sexual partners (4.1 vs 2.5; p<0.05) between positive and negative women. No difference was observed in age of first coitus, STD history, the use of barrier method or socioeconomic level. However, the probability of being carrier increases as greater is the number of sexual partners, especially when the use of barrier method is low. The latest is not related to the socioeconomic level. One of 12 to 18 women at this age range will have asymptomatic infection. The current prevalence and its variability substantiates the C. trachomatis screening and periodic surveillance.

    Background. Obesity has reached epidemic proportions in dogs and, as in humans, cost of care has increased due to associated comorbidities. In humans, asymptomatic urinary tract infections (UTI) may be more prevalent in the obese. Asymptomatic bacteriuria (AB) is the term used when UTI are asymptomatic. We hypothesized that morbidly obese dogs are similarly more likely to have asymptomatic bacteriuria than lean, overweight, and moderately obese dogs. Methods. A retrospective study was undertaken to explore a possible association between obesity and asymptomatic bacteriuria. Records from lean, overweight, and obese dogs receiving both a dual energy absorptiometry (DXA) scan and urine culture were included. Results. Six positive urine cultures were identified among 46 dogs fulfilling search criteria. All six positive cultures were found in dogs with body fat percentage of >45%. In dogs with body fat percentage of <45%, there were no positive urine cultures. Discussion. There was an increased prevalence of asymptomatic bacteriuria in the morbidly obese dogs in this study compared to those that were lean, overweight, or moderately obese. Whether antibiotic therapy is necessary in such cases is still being debated, but because asymptomatic bacteriuria may be associated with ascending infections, uroliths, or other complications, the data reported herein support the screening of obese patients for bacteriuria.

    Subcutaneous or deep granuloma annulare is a benign asymptomatic condition characterized by firm asymptomatic nodules in deep subcutaneous tissues that may be associated with intradermal lesions. A 53-year-old female presented with asymptomatic skin-colored, firm nodules over the right ring finger. Histopathology revealed a palisading granuloma with central degenerated collagen and mucin deposition in the dermis suggestive of granuloma annulare. Isolated and unilateral involvement of a single digit with clusters of nodules of subcutaneous granuloma annulare (GA) in an adult is rare and differentiation from its simulator rheumatoid nodule is essential.

    Sonography has detected urate deposits in 34%-42% of the patients with asymptomatic hyperuricemia. This may prompt reclassification of asymptomatic hyperuricemia into "asymptomatic gout" and consideration of urate lowering therapy (ULT) to resolve urate deposits. In patients with gout and no visible tophi, sonography has detected urate deposits in half of the patients. This may allow diagnosing "tophaceous gout" and influencing the serum urate target level, prophylaxis to avoid acute gout flares during ULT, and clinical follow-up. Current accessibility to sonography may better classify patients with hyperuricemia and gout and contribute to delineate therapeutic objectives and clinical guidance.

    We report a case of prenatally diagnosed congenital perineal mass which was combined with anorectal malformation. The mass was successfully treated with posterior sagittal anorectoplasty postnatally. On ultrasound examination at a gestational age of 23 weeks the fetal perineal mass were found on the right side. Any other defects were not visible on ultrasonography during whole gestation. Amniocentesis was performed to evaluate the fetal karyotyping and acetylcholinesterase which were also normal. As the fetus grew up, the mass size was slowly increased more and more. At birth, a female neonate had a perineal mass on the right side as expected. During operation, the anal sphincteric displacement was found near the mass and reconstructed through posterior sagittal incision. This is the first reported case of prenatally diagnosed congenital perineal mass, after birth which was diagnosed as lipoblastoma and even combined with anorectal malformation. This case shows that it can be of clinical importance to be aware of this rare fetal perineal mass in prenatal diagnosis and counseling.

    We examined the interaction between the sacral neural system and the anorectal activity using a technique comprising repetitive magnetic stimulation. Thirteen control children without any bowel dysmotility (age range; 3 month old to 15 year old), 20 patients with chronic constipation (1 month old to 14 year old), and nine pre-operative patients with Hirschsprung's disease (1 month old to 6 year old) were examined. Magnetic stimulation was applied at the S3 level using the MagPro (Medtronic) device while simultaneously performing manometric recordings of the anorectal activity. In the 13 controls and the 20 patients with chronic constipation, the rectoanal reflex was demonstrated by balloon rectal dilatation. The sphincter response to magnetic stimulation was biphasic in the controls, consisting of an initial rise followed by a decrease in the sphincter pressure, while it varied among the patients with chronic constipation including a biphasic response in 16 patients, no response in three patients, and only a transient rise in pressure in one patient. In nine pre-operative patients with Hirschsprung's disease, no rectoanal reflex was observed, however, the sphincter pressure increased due to magnetic stimulation in six patients, while three patients exhibited no recordable responses. These results suggest that the repetitive magnetic stimulation technique is a valuable modality for investigating the neural interaction between the sacral nervous system and the anorectum.

    There are no in vitro studies of congenital pouch colon (CPC) associated with anorectal malformation (ARM) to understand its mechanism of contractility. There is no consensus regarding the utilization of the CPC in repair of anorectal malformation. In view of the above, it was decided to carry out detailed in vitro physiological study of the excised CPC. The excised specimens of CPC were taken and 15- to 20-mm long both longitudinal and transverse strips of muscle were obtained both from the proximal and distal part. Contraction was recorded using software chart-5 for windows. Drugs used were acetylcholine, histamine, adrenaline, atropine and pheniramine maleate. The amplitude of contractions was converted to tension gram and then the tension so developed was expressed as tension per unit mass (per gram of wet tissue). There were total of 21 specimens of high ARM with CPC. Five specimens were of the complete pouch, which did not show a response to any drug and the remaining 16 had an incomplete pouch. The mean longitudinal and circular muscle contractions of these 16 samples were statistically higher for the proximal segment than the distal segment both for acetylcholine and histamine. The effect of atropine was not significant but that of adrenaline and pheniramine maleate were significant on the distal segment muscle. Congenital pouch colon being deficient or having poorly developed receptors in their wall can not function properly as a reservoir for faeces and, hence, it should be excised to allow adequate function.

    This study investigated whether the addition of 25 microg fentanyl to an ultra-low (sub-anaesthetic) dose of intrathecal bupivacaine provides adequate anaesthesia for out-patient anorectal surgery, without increasing side-effects or delaying hospital discharge. Patients were randomly allocated to receive 2.5 mg 0.5% bupivacaine plus 25 microg fentanyl (group BF, n = 18) or 5 mg 0.5% bupivacaine alone (group B, n = 17). There were no significant differences in intra-operative outcomes, but mean recovery and discharge times were significantly shorter in group BF. There were no between-group differences in hypotension, bradycardia or respiratory depression and post-operative complications were comparable, apart from pruritus which was significantly more frequent in group BF. Fewer patients requested analgesic medication in the early post-operative period in group BF than in group B. In conclusion, 25 microg intrathecal fentanyl added to ultra-low dose (2.5 mg) bupivacaine provided good-quality spinal anaesthesia and reduced post-operative analgesic requirement in patients undergoing ambulatory anorectal surgery.

    Cold is thought to provoke angina in patients with coronary disease either by an increase in myocardial demand or an increase in coronary vascular resistance. We investigated and compared the effects of cold pressor stimulation and symptom-limited supine bicycle exercise on regional myocardial perfusion in 35 patients with stable angina and coronary disease and in 10 normal subjects. Regional myocardial perfusion was assessed with positron emission tomography and rubidium-82. Following cold pressor stimulation 24 of 35 patients demonstrated significant abnormalities of regional myocardial perfusion with reduced cation uptake in affected regions of myocardium: 52 +/- 9 to 43 +/- 9 (p less than 0.001 vs normal subjects). Among these 24 patients only nine developed ST depression and only seven had angina. In contrast, 29 of 35 patients underwent supine exercise, and abnormal regional myocardial perfusion occurred in all 29, with a reduction in cation intake from 48 +/- 10 to 43 +/- 14 (p less than 0.001 vs normal subjects). Angina was present in 27 of 29 and ST depression in 25 of 29. Although the absolute decrease in cation uptake was somewhat greater following cold as opposed to exercise, the peak heart rate after cold was significantly lower than that after exercise (82 +/- 12 vs 108 +/- 16 bpm, p less than 0.05). Peak systolic blood pressures after cold and exercise were similar (159 +/- 24 vs 158 +/- 28). Thus, cold produces much more frequent asymptomatic disturbances of regional myocardial perfusion in patients with stable angina and coronary disease than is suggested by pain or ECG changes.

    Infection with genital herpes simplex virus (HSV) remains a common viral sexually transmitted disease, often subclinical and a major worldwide problem of women of reproductive age group. Herpes cervicitis is an unusual presentation of Herpes simplex virus infection in females. The finding of herpes cervicitis on routine pap smear of an asymptomatic woman on Intrauterine contraceptive device still further supports the need for increased awareness on the possibility of Herpes simplex virus infection among women, particularly those on Intrauterine contraceptive device. The index case is a 28 years old Nigerian female who was referred to our Special Treatment Clinic on account of an abnormal pap smear cytology which was in keeping with Herpes cervicitis. There was no history of genital ulcer in this patient; however ELISA for HSV 2 IgM was positive in her. We therefore describe a case of herpes cervicitis in an asymptomatic woman on intrauterine contraceptive device. This case highlights to clinicians the need to be aware of the possibility of this association and to carry out relevant investigations so as to identify and treat these patients appropriately. Therefore, there is a need to put in place adequate public health intervention strategy to prevent genital herpes in women of reproductive age group with a view to preventing the possibility of congenital herpes in subsequent pregnancy.

    We compared clinical and arteriographic features in 106 patients with symptomatic unilateral carotid territory occlusive disease to determine the frequency and distribution of occlusive arterial lesions in asymptomatic vessels. Among black patients who were predominantly from Chicago, young, and female, there were fewer transient ischemic attacks and myocardial infarcts, less claudication, and more asymptomatic lesions of the supraclinoid internal carotid artery, anterior cerebral artery stem, and the middle cerebral artery stem. Among white patients predominantly from New England, elderly, and male, there was more frequent and severe occlusive asymptomatic disease at extracranial carotid and vertebral artery sites. Knowledge of the distribution of asymptomatic lesions will help guide evaluation and treatment strategies for patients with occlusive cerebrovascular disease.

    Neuropsychological and immunological parameters were studied in 36 AIDS patients with early disease and without clinical, laboratory, and neuroradiological signs of CNS impairment, and also in 33 asymptomatic HIV seropositive subjects. Many AIDS patients performed abnormally on timed psychomotor tasks, tasks involving sequencing and "set-shifting", and memory tasks stressing attention, learning, active retrieval, and monitoring of information. Asymptomatic HIV seropositive subjects as a group did not perform significantly worse than controls. However, on the basis of a cut off number of pathological performances on neuropsychological tasks, 52.8% of AIDS and 30.3% of asymptomatic HIV seropositive subjects had cognitive impairment, compared with 3.9% of HIV seronegative controls. Low values of CD4+ cells and of CD4+/CD8+ ratio and high titres of P-24 antigen in the blood prevailed among subjects with cognitive impairment, especially in the asymptomatic HIV seropositive group.

    American cutaneous leishmaniasis (ACL) is a major public health problem caused by vector-borne protozoan intracellular parasites from the genus Leishmania, subgenera Viannia and Leishmania. Asymptomatic infection is the most common outcome after Leishmania inoculation. There is incomplete knowledge of the biological processes explaining the absence of signs or symptoms in most cases while other cases present a variety of clinical findings. Most studies of asymptomatic infection have been conducted in areas of endemic visceral leishmaniasis. In contrast, asymptomatic ACL infection has been neglected. This review is focused on the following: (1) epidemiological studies supporting the existence of asymptomatic ACL infection and (2) immunological studies conducted to understand the mechanisms responsible for controlling the parasite and avoiding tissue damage.

    This study demonstrated that bovine herpesvirus 5 (BoHV)-5 infected calves can develop encephalitis and remain asymptomatic. Seven calves were infected intranasally and monitored for 30 days. Cerebrospinal fluid (CSF) analysis was performed from the onset of neurological signs. Multiple sections of brain and the trigeminal ganglion were submitted to histopathology. Virus detection (PCR and isolation) was performed on CSF and tissues. Four calves developed signs of neurologic disease and died. Three calves remained asymptomatic and were euthanized 30 days post-infection. Cerebrospinal fluid mononuclear pleocytosis occurred in symptomatic and asymptomatic calves. BoHV-5 was isolated and viral DNA was detected in multiple areas of the encephalon of all calves. The viral DNA was detected in the CSF of 2 calves showing neurological signs. Histologically, inflammation was noted in the brain of all calves and confirmed that the encephalitis caused by BoHV-5 may be mild and asymptomatic. PMID:22654135

    The role played by vessel disease in stroke-related cognition dysfunction is unclear. We assessed the impact of significant atherosclerotic disease on cognition—even in patients asymptomatic for stroke. We hypothesized that patients would perform poorly relative to controls, but that symptomatic/asymptomatic status (history of stroke/transient ischemic attack) would have no effect. Fifty-two carotid endarterectomy candidates with >60% carotid stenosis and 17 controls underwent a 60-min neuropsychological test protocol. Symptomatic and asymptomatic patients showed deficits in executive function, delayed verbal recall, and general knowledge. Patients symptomatic for stroke also performed worse on tests of language and motor/visuomotor ability. Symptomatic and asymptomatic patients differed in working memory and language task performance. Although all patients showed deficits in executive function and memory, only symptomatic patients showed additional deficits in language and motor function. Cognitive abnormalities in patients viewed as “asymptomatic” for stroke underscore the need for early identification and treatment. PMID:26663810

    Rectobladder neck fistula is the highest and most complex anorectal malformation in boys and the only one that requires an abdominal approach, open or laparoscopic, for repair. The aim of this study was to describe the unique characteristics of rectobladder neck fistulas that warrant special attention and to describe the associated anatomic variants in the genitourinary tract. The database of a tertiary medical center was retrospectively reviewed for all patients treated for rectobladder neck fistula, by our team in 1980-2011. Data on surgical history, associated and functional defects, treatment and outcome were collected by chart review. The study group included 111 patients. The most common anatomic urologic defect was a single kidney in 37 patients (33.3%) and the most common functional urologic defect was vesicoureteral reflux in 40 patients (36%), including 11/37 patients with a single kidney (29.7%). Of the 40 patients who underwent cystoscopy, 16 (40%) had a higher than normal location of the verumontanum. Follow-up ranged from 2 to 290months (median 59). Urinary continence was achieved in 40 of the 61 patients (65.5%) for whom data were available, and fecal continence was achieved in 9 of the 69 patients (13%) for whom data were available. A sacral ratio of 0.4 or less was associated with lower rates of urinary control (23%) and fecal control (0%), relative to higher ratios. Twenty stomas (18%) were found to be located too distally, limiting the availability of the bowel for a pull through. Rectobladder neck fistula carries a poor prognosis for bowel control and is associated with a high rate of urinary malformations that require long-term care. Pediatric surgeons need to be aware of these complications in order to provide proper treatment and parental counseling. Intra-vesical verumontanum is found in a surprisingly high percentage of patients. The combination of a single kidney with vesicoureteral reflux is common and should be closely followed to avoid

    Are anorectal malformations (ARMs) associated with previous miscarriages or single nucleotide polymorphisms (SNPs) in the Bone Morphogenetic Protein 4 (BMP4) and GLI family zinc finger 2 (GLI2) genes? The SNP rs3738880 in GLI2 and miscarriages were associated with ARM, especially in patients with multiple congenital anomalies (MCA). ARM are one of the most common birth defects of the gastrointestinal tract. The etiology is likely to be multifactorial, involving both environmental and genetic factors. SNPs in BMP4 and GLI2 genes were associated with ARM in non-Caucasian populations. During a patient information day, several mothers of ARM patients reported their concerns about previous miscarriages. A case-control study was performed among 427 ARM patients and 663 population-based controls. We examined the associations of ARM with SNPs in GLI2 and BMP4 using DNA samples of the children and associations with previous miscarriages using parental questionnaires. In addition, gene-gene and gene-environment interaction analyses were performed. The SNP rs3738880 in GLI2 was associated with ARM, especially in patients with MCA (homozygous GG-genotype: odds ratio (OR): 2.1; 95% CI: 1.2, 3.7). We identified previous miscarriages as a new risk factor for ARM, especially when occurring in the pregnancy directly preceding the index pregnancy and in patients with MCA (OR: 2.1; 95% CI: 1.3, 3.5). No association with rs17563 in BMP4, nor gene-gene or gene-environment interactions were found. The possibility of recall errors for previous miscarriage, but we expect these errors to be limited, as a miscarriage is a major life event. In addition, potential misclassification regarding miscarriages and stillbirth, but sensitivity analyses showed that this did not influence our results. This study showed associations of ARM with rs3738880 in GLI2 and with previous miscarriages. Both associations were stronger in patients with MCA, showing the importance of stratifying the analyses by

    A radiographic stereophotogrammetric technique (SPG) was used to evaluate quantitatively the presence of early femoral prosthesis subsidence after total hip arthroplasty (THA). This paper focuses on the measurement of subsidence in 12 patients who remained asymptomatic during the first two years after surgery. Only one of these had SPG estimated subsidence in excess of one millimeter at any timepoint. These findings are consistent with the conclusion that early postoperative subsidence is not a common finding among asymptomatic THA patients.

The profile of diseases was strongly correlated to sexual life-style. Amoebiasis and giardiasis were found respectively in 31.9% and 13.8% of homosexuals. None of the heterosexuals had pathogenic protozoa. Protozoal infections were correlated to anilingus. Forty-five percent of the patients were infected in Denmark. Travelling to endemic areas was of no obvious importance. Among males with homosexual partners, 14% had rectal infections. Gonococcal and chlamydial infections were equally frequent. Three percent had symptomatic anorectal herpes simplex infection and 11% anal warts. Gastrointestinal symptoms were not reliable indicators of gastrointestinal infection; symptoms were claimed frequently among homosexuals without infections compared to heterosexuals. Urethral gonorrhoea and/or chlamydia infections were diagnosed in 39% of the heterosexuals compared to only 10% of the homo-bisexuals. Twelve percent of the homosexuals had untreated early syphilis, whereas syphilis was exceptional among heterosexuals. The total burden of infections expressed as the actual number of infections was largest among homosexuals, 40.4%, 22.4%, and 5.3% having one, two, and three infections respectively.

    This article gives a clinically oriented overview of forensically relevant forms of sexual sadism disorder and its specific relationship to sexual homicide. In sexual homicide perpetrators, peculiar patterns of sexual sadism may be a motivational pathway to kill. Sexual sadism increases the risk for reoffending in sexual offenders. Through psychotherapy and pharmacological interventions, treatment of sadistic sex offenders has to consider special characteristics that may be different from those of nonsadistic sex offenders. Many of these offenders share a combination of sexual sadistic motives and an intact self-regulation, sometimes combined with a high level of sexual preoccupation. Copyright © 2014 Elsevier Inc.

    Sexually transmitted infections (STIs) are among the most common notifiable health problems worldwide, with particularly high rates in developing countries. Men and women with multiple sexual partners at home or a previous history of STIs are more likely to have casual sexual exposure (CSE) while travelling. Over the last several decades 5% to even 50% of short-term travellers engaged in CSE during foreign trips. It is estimated that only 50% of travellers use condoms during casual sex abroad. Sexual contact with commercial sex workers is an exceptionally high-risk behaviour. The common risk factor is also young age. Adolescents and young adults constitute 25% of the sexually active population, but represent almost 50% of all new acquired STIs. Many STIs are asymptomatic and therefore can be difficult to identify and control. The clinical manifestation of STIs can be grouped into a number of syndromes, such as genital ulcer or erosion, urethral or vaginal discharge, pelvic inflammatory disease. STIs are divided into curable infections caused by bacteria (gonorrhoea, chlamydiasis, syphilis, chancroid, lymphogranuloma venereum, granuloma inguinale) or protozoa (trichomoniasis) and incurable viral infections (genital herpes, genital warts, HIV). STIs are not only a cause of acute morbidity, but may result in complications including male and female infertility, ectopic pregnancy, cervical cancer, premature mortality or miscarriage. Monogamous sex with a stable, uninfected partner or sexual abstinence remains the only way to avoid the risk of becoming infected with STIs.

    Rotavirus is a major cause of infectious intestinal disease in young children; a substantial prevalence of asymptomatic infection has been reported across all age groups. In this study, the authors determined characteristics of asymptomatic rotavirus infection and potential risk factors for infection. Healthy persons were recruited at random from the general population of England during the Study of Infectious Intestinal Disease in England (1993-1996). Rotavirus infection was identified using reverse-transcription polymerase chain reaction. Multivariable logistic regression was used to compare exposures reported by participants with rotavirus infection with those of participants who tested negative. Multiple imputation was used to account for missing responses in the data set. The age-adjusted prevalence of asymptomatic rotavirus infection was 11%; prevalence was highest in children under age 18 years. Attendance at day care was a risk factor for asymptomatic rotavirus infection in children under age 5 years; living in a household with a baby that was still in diapers was a risk factor in older adults. The results suggest that asymptomatic rotavirus infection is transmitted through the same route as rotavirus infectious intestinal disease: person-to-person contact. More work is needed to understand the role of asymptomatic infections in transmission leading to rotavirus disease.

    Asymptomatic bacteriuria in pregnancy is the major risk factor for symptomatic urinary tract infection during pregnancy. Screening and identification of bacteriuria during pregnancy have been recommended. To determine the prevalence and pattern of asymptomatic bacteriuria associated with pregnancy. The study was a descriptive, cross sectional survey of pattern of asymptomatic bacteriuria among consecutive patients presenting for the first antenatal visit at a University College Hospital, during a period of two months. Relevant information obtained from all the patients recruited for the study included age, parity, educational level, gestational age and occupation of participant. Haemoglobin electrophoresis patterns were also retrieved and recorded. Main outcome measures were prevalence of asymptomatic bacteriuria, bacterial isolates and their antibiotic sensitivities. There were 205 eligible participants with a mean age of 30.6 ± 4.3 years and a mean gestational age at booking of 20.9 ±7.0 weeks. The prevalence of asymptomatic bacteriuria was 22(10.7%). The isolated pathogens were predominantly coliforms (Klebsiella and E. coli) accounting for 45.5% and Staphylococcus saprophyticus (27.3%). Only gentamycin, nitrofurantoin and ofloxacin demonstrated high efficacy against these uropathogens with antibiotic sensitivity rates of 72.7%-81.8%. Prevalence of asymptomatic bacteriuria in this centre is relatively high. This underscores the need for routine screening of pregnant women for bacteriuria.

    Asymptomatic Plasmodium infection carriers represent a major threat to malaria control worldwide as they are silent natural reservoirs and do not seek medical care. There are no standard criteria for asymptomaticPlasmodium infection; therefore, its diagnosis relies on the presence of the parasite during a specific period of symptomless infection. The antiparasitic immune response can result in reducedPlasmodium sp. load with control of disease manifestations, which leads to asymptomatic infection. Both the innate and adaptive immune responses seem to play major roles in asymptomatic Plasmodiuminfection; T regulatory cell activity (through the production of interleukin-10 and transforming growth factor-β) and B-cells (with a broad antibody response) both play prominent roles. Furthermore, molecules involved in the haem detoxification pathway (such as haptoglobin and haeme oxygenase-1) and iron metabolism (ferritin and activated c-Jun N-terminal kinase) have emerged in recent years as potential biomarkers and thus are helping to unravel the immune response underlying asymptomatic Plasmodium infection. The acquisition of large data sets and the use of robust statistical tools, including network analysis, associated with well-designed malaria studies will likely help elucidate the immune mechanisms responsible for asymptomatic infection.

    Transcutaneous electrical tibial nerve stimulation (TENS) is of growing interest for the treatment of fecal incontinence (FI), but its mechanism of action remains uninvestigated. We aimed to further assess the anorectal response to TENS in a dynamic model. We performed a placebo-controlled, randomized, double-blinded crossover study in 19 patients suffering from FI to assess the effects of TENS on anorectal function. Anorectal physiology and perception were recorded through two sequences of rectal isobaric distension using an electronic barostat device to measure anal and rectal pressures, rectal volumes, and perception scores. Maximal rectal pressure and volume variation were affected by TENS, with higher mean maximal rectal pressure (5.33 and 4.06 mmHg in the active and sham TENS respectively, p < 0.0001) and lower volume variation (11.45 and 14.7 mL in the active and sham stimulation respectively, p < 0.05). Rectal compliance was not modified by active TENS. Pressure of the upper anal canal was significantly lower with raised isobaric distension in sequences assigned to active TENS. Acute TENS modified anorectal physiology by strengthening the myogenic response to distension rather than increasing muscle relaxation and related rectal compliance in patients with FI. © 2013 John Wiley & Sons Ltd.

    Surgical treatment for anorectal fistula may be difficult because of the risk of recurrence, prolonged healing or anal incontinence following the operation. To analyze the experience with the surgical management of ano-rectal fistula during a period of 17 years. The medical records of 105 patients with anorectal fistulas were reviewed retrospectively, with analysis of demographic and clinical data, operative treatment, and results. There were 73% men and 27% women. Mean age was 45 years. 86% had an underlying chronic disease, most frequently diabetes mellitus (21%) and obesity (14%). No anatomic classification of the fistulous tract was done in 86% of cases, and inter-sphincteric tracts were the most frequent type in the classified cases. In 90% of cases, treatment was fistulectomy. Complications occurred in 13% of cases, mainly delayed healing (6.5%). Recurrent disease was documented in 11 cases (10%), and the majority were treated with a new fistulectomy. There were no cases with anal incontinence following the operation. The necessity of performing the anatomic classification of ano-rectal fistula should be emphasized. Fistulectomy was the most frequent surgical procedure.

    There has been considerable interest in the development of innovative service delivery modules for prioritizing resources in sexual health delivery in response to dwindling fiscal resources and rising infection rates. This study aims to derive and validate a risk scoring algorithm to accurately identify asymptomatic patients at increased risk for chlamydia and/or gonorrhea infection. We examined the electronic records of patient visits at sexual health clinics in Vancouver, Canada. We derived risk scores from regression coefficients of multivariable logistic regression model using visits between 2000 and 2006. We evaluated the model's discrimination, calibration, and screening performance. Temporal validation was assessed in visits from 2007 to 2012. The prevalence of infection was 1.8% (n = 10,437) and 2.1% (n = 14,956) in the derivation and validation data sets, respectively. The final model included younger age, nonwhite ethnicity, multiple sexual partners, and previous infection and showed reasonable performance in the derivation (area under the receiver operating characteristic curve = 0.74; Hosmer-Lemeshow P = 0.91) and validation (area under the receiver operating characteristic curve = 0.64; Hosmer-Lemeshow P = 0.36) data sets. A risk score cutoff point of at least 6 detected 91% and 83% of cases by screening 68% and 68% of the derivation and validation populations, respectively. These findings support the use of the algorithm for individualized risk assessment and have important implications for reducing unnecessary screening and saving costs. Specifically, we anticipate that the algorithm has potential uses in alternative settings such as Internet-based testing contexts by facilitating personalized test recommendations, stimulating health care-seeking behavior, and aiding risk communication by increasing sexually transmitted infection risk perception through the creation of tailored risk messages to different groups.

    Trichothecene mycotoxins, potent translational inhibitors that are associated with human food poisonings and damp-building illnesses, are of considerable concern to animal and human health. Food refusal is a hallmark of exposure of experimental animals to deoxynivalenol (DON) and other Type B trichothecenes but less is known about the anorectic effects of foodborne Type A trichothecenes (e.g., T-2 toxin, HT-2 toxin), airborne Type D trichothecenes (e.g. satratoxin G [SG]) or functionally analogous metabolites that impair protein synthesis. Here, we utilized a well-described mouse model of food intake to compare the anorectic potencies of T-2 toxin, HT-2 toxin, and SG to that of emetine, a medicinal alkaloid derived from ipecac that inhibits translation. Intraperitoneal (IP) administration with T-2 toxin, HT-2 toxin, emetine and SG evoked anorectic responses that occurred within 0.5 h that lasted up to 96, 96, 3 and 96 h, respectively, with lowest observed adverse effect levels (LOAELs) being 0.1, 0.1, 2.5 and 0.25 mg/kg BW, respectively. When delivered via natural routes of exposure, T-2 toxin, HT-2 toxin, emetine (oral) and SG (intranasal) induced anorectic responses that lasted up to 48, 48, 3 and 6 h, respectively with LOAELs being 0.1, 0.1, 0.25, and 0.5 mg/kg BW, respectively. All four compounds were generally much more potent than DON which was previously observed to have LOAELs of 1 and 2.5 mg/kg BW after IP and oral dosing, respectively. Taken together, these anorectic potency data will be valuable in discerning the relative risks from trichothecenes and other translational inhibitors of natural origin. PMID:25932382

    Sexually transmitted infections (STIs) are highly prevalent and cause a wide spectrum of disease. However, the majority of these infections may be unrecognized due to lack of overt signs or symptoms of infection. Asymptomatic infections remain significant as a result of the potential for long-term sequelae, predominately in women, and the risks of complications during pregnancy as well as mother-to-child transmission. Laboratory diagnostics play an important role in identifying infection and in public health efforts to reduce the prevalence of these diseases. Serologic diagnosis is appropriate for syphilis and, in some settings, for herpes infections. However, the organisms that cause discharge such as Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis and Mycoplasma genitalium are best diagnosed using molecular assays. Currently available molecular assays are suitable for use with non-invasively collected sample types, most notably vaginal swabs for women thus expanding the potential reach of STI control programs to include non-clinic based screening.

    Several studies indicate that self-efficacy may have profound positive effects on health promotion, clinical practice and other outcomes, like patients' satisfaction and quality of life. However no studies on self-efficacy have been conducted in anorectal malformation (ARM) patients. Aim of the present study is to analyze the relationships between self-efficacy and satisfaction with postoperative care in ARM patients or in their parents and between self-efficacy, body image and sexual functioning in adult ARM patients. A total of 237 patients from 2 to 49 years old (mean age = 13.35 years old) participated in the study. Questionnaires were sent to members of the Italian Association for Anorectal Malformation (AIMAR) by ordinary mail. All subjects were asked to fill in the AIMAR questionnaire in which information about the perceived severity of malformation and postoperative care satisfaction were collected. For patients under 16 years old, parents were asked to fill in a questionnaire and a parent self-efficacy scale concerning the perceived ability to overcome possible difficulties related to ARM. Participants above 16 years of age were asked to fill in the questionnaire, a self-efficacy scale and some body image and sexual functioning items. The main findings indicate that those patients who feel more efficacious are those who feel less embarrassed and shame about their body, feel less frequently unsatisfied of their body and their physical condition, and have the perception to be less limited in their sexual activities. Considering patients under 16 years old, results indicate that more parents feel efficacious, the more they are satisfied of the postoperative care, especially of some health care providers. In ARM patients self-efficacy and parents self efficacy are correlated to important outcomes, respectively body image and sexual functioning in adults and postoperative care satisfaction in parents of those under 16 years old.

    Anorectal malformations are inborn developmental defects that are associated with multiple functional Impairments (especially incontinence) and psychosocial burden with a major impact on body schema and self-esteem. Child psychology and psychiatry research begin to identify disorder-dependent and -independent risk and protective factors that predict the outcome of psychological adaptation and quality of life. The present paper analyses the interference of structural and functional disease parameters with the achievement of regular developmental tasks, presents a hypothetical conceptual framework concerning the development of psychological adaptation and quality of life in ARM, integrates findings from empirical research with the framework presented and outlines strategies of psychological support from a cognitive-behavioural perspective within a multidisciplinary treatment approach to enhance medical, functional, and psychosocial quality of life.

    Asymptomatic bacteriuria is one of the most common and important bacterial infections during pregnancy and can result in progressive infections and endanger maternal as well as fetal health. In this study, we assessed the relationship between asymptomatic bacteriuria and pre-eclampsia. In this case-control study, pregnant women who presented to Imam Reza Hospital in Kermanshah in 2013-14 were studied. The minimum sample size was calculated as 125 pregnant women in each group with a total of 250 subjects. There were 125 women with pre-eclampsia and 125 women without pre-eclampsia (control group). Matching was done for age, gestational age, and parity between case and control groups. Matching was verified by a P value of 0.061 for maternal age and gestational age and 0.77 for parity. The statistical analyses were done by applying the chi-squared test and determining odds ratio (OR) for having bacteriuria in univariate logistic regression as well as multivariate regression with adjusting the effect of maternal age, gestational age, and parity. Pyuria and bacteriuria were significantly more common in pre-eclampsia group than in control group. The results showed that a significant association existed between asymptomatic bacteriuria and pre-eclampsia. The rate of asymptomatic bacteriuria was 6.8 times higher in women with pre-eclampsia compared to those without pre-eclampsia. Further studies are required for better clarification of association between asymptomatic bacteriuria and pre-eclampsia. PMID:26925912

    Significant asymptomatic bacteriuria is a risk factor for symptomatic urinary infection and septicemia among predisposed individuals such as diabetics. We investigated the pattern of asymptomatic bacteriuria among our type 2 diabetics with a view to documenting the prevalence, type of organisms responsible and the antibiotic susceptibility pattern. One hundred and twenty-four type 2 Nigerian diabetics (55 males and 69 females) submitted midstream urine specimens for culture. Thirty-three patients had significant bacteriuria (9 males and 24 females), showing the frequency of occurrence of asymptomatic bacteriuria to be 26.6%. The most common organism isolated was Klebsiella pneumonia at 42.4%. Gram-negative bacilli made up about 23 (69.7%) of the isolates. Isolates were poorly sensitive to the readily available antibiotics (ampicillin, tetracycline and cotrimoxazole), but a large number of the organisms isolated were sensitive to nitrofurantoin, gentamicin, ciprofloxacin and ofloxacin. Sensitivity to erythromycin, nalidixic acid and cefuroxime was moderate. Asymptomatic bacteriuria is, thus, more prevalent among the Nigerian diabetic population than in the non-diabetics. A changing pattern of disease is observed with Klebsiella sp. now accounting for the majority of asymptomatic bacteriuria among diabetics. The organisms are not sensitive to the commonly available antibacterial agents. PMID:12793791

    Coping strategies have been acknowledged as crucial for the well-being and for health-related quality of life (HRQoL). The main aim of the present study is to determine whether different types of coping strategies predict HRQoL in patients born with ARM, above and beyond the variance explained by fecal and urinary continence. 71 adult patients from the Italian Parents' and Patients' Organization for Anorectal Malformations (AIMAR) participated in the study. Participants completed measures of fecal and urinary continence of the Hirschsprung Disease/Anorectal Malformation Quality of Life (HAQL) (Hanneman et al. in Dis Col Rect 44:1650-1660, 2001), the Short Form Health Survey (SF-36) (Apolone and Mosconi in J Clin Epidemiol 51:1025-1036, 1998), and the Brief Coping Orientation to Problems Experienced (COPE) Inventory (Carver in Int J Behav Med 4:92-100, 1997), which measures different coping strategies: maladaptive, problem-focused and emotion-focused. Hierarchical regression analyses showed that fecal continence (β = 0.53, p < 0.01) and urinary continence significantly predict (β = 0.23, p < 0.05) Physical HRQoL. Fecal continence (β = 0.36, p < 0.01) and maladaptive coping strategies significantly predict (β = -0.27, p < 0.05) Mental HRQoL. Besides considering the importance of fecal and urinary continence for Physical HRQoL, these findings indicate that maladaptive coping strategies are associated with worse Mental HRQoL. Interventions aimed at enhancing the patients' HRQoL should target coping strategies by reducing denial, behavioral disengagement, substance abuse, and self-blame.

    Anorexia nervosa often requires inpatient treatment that includes psychotherapeutic intervention in addition to physical and nutritional management for severe low body weight. However, such patients sometimes terminate inpatient treatment prematurely because of resistance to treatment, poor motivation for treatment, unstable emotions, and problematic behaviors. In this study, the psychopathological factors related to the personality of anorexic patients that might predict discontinuation of inpatient treatment were investigated using the Minnesota Multiphasic Personality Inventory (MMPI). Subjects were 75 consecutive anorectic inpatients who received cognitive behavioral therapy with a behavior protocol governing privileges in a university hospital based general (not psychiatric) ward. The MMPI was done on admission for all patients. A comparison was done of patients who completed the process of inpatient treatment, including attainment of target body weight (completers), and patients who dropped out of inpatient treatment (dropouts). No significant differences between completers (n = 51) and dropouts (n = 24) were found in the type of eating disorder, age of onset, duration of illness, age, or BMI at admission. Logistic regression analysis found the MMPI scales schizophrenia (Sc), hypomania (HYP), deviant thinking and experience, and antisocial attitude to be factors predicting completion or dropout. Dropouts have difficulty adapting to inpatient treatment protocols such as our behavior protocol governing privileges because they have social and emotional alienation, a lack of ego mastery (Sc), emotional instability (HYP) and an antisocial attitude. As a result, they have decreased motivation for treatment, leave the hospital without permission, attempt suicide, or shoplift, which leads them to terminate inpatient treatment prematurely. Treatments based on cognitive behavioral therapy with a behavior protocol governing privileges should be carefully adopted for

    Amylin reduces meal size by activating noradrenergic neurons in the area postrema (AP). Neurons in the AP also mediate the eating-inhibitory effects of salmon calcitonin (sCT), a potent amylin agonist, but the phenotypes of the neurons mediating its effect are unknown. Here we investigated whether sCT activates similar neuronal populations to amylin, and if its anorectic properties also depend on AP function. Male rats underwent AP lesion (APX) or sham surgery. Meal patterns were analysed under ad libitum and post-deprivation conditions. The importance of the AP in mediating the anorectic action of sCT was examined in feeding experiments of dose-response effects of sCT in APX vs. sham rats. The effect of sCT to induce Fos expression was compared between surgery groups, and relative to amylin. The phenotype of Fos-expressing neurons in the brainstem was examined by testing for the co-expression of dopamine beta hydroxylase (DBH) or tryptophan hydroxylase (TPH). By measuring the apposition of vesicular glutamate transporter-2 (VGLUT2)-positive boutons, potential glutamatergic input to amylin- and sCT-activated AP neurons was compared. Similar to amylin, an intact AP was necessary for sCT to reduce eating. Further, co-expression between Fos activation and DBH after amylin or sCT did not differ markedly, while co-localization of Fos and TPH was minor. Approximately 95% of neurons expressing Fos and DBH after amylin or sCT treatment were closely apposed to VGLUT2-positive boutons. Our study suggests that the hindbrain pathways engaged by amylin and sCT share many similarities, including the mediation by AP neurons.

    Sexually transmitted infections (STIs) are responsible for an enormous burden of morbidity and mortality. Worldwide, millions of cases of STIs, such as syphilis, chlamydia, or gonorrhoea occur every year, and there is now an increase in antimicrobial resistance in pathogens, such as gonococcus. Delay in diagnosis is one of the factors that justifies the difficulty in controlling these infections. Rapid diagnostic tests allow the introduction of aetiological treatment at the first visit, and also leads to treating symptomatic and asymptomatic patients more effectively, as well as to interrupt the epidemiological transmission chain without delay. The World Health Organisation includes these tests in its global strategy against STIs.

    Adolescents are often at higher risk for acquiring sexually transmitted infections (STIs). Medical providers should be alert for both asymptomatic and symptomatic STIs, and follow appropriate screening guidelines. Moreover, providers need to know how to best administer adolescent-friendly confidential care, treatment, and health education in the primary care setting. This article addresses the most common adolescent STIs and pertinent recommendations for screening, diagnosis, and management of infections, in addition to a brief focused discussion on human immunodeficiency virus and adolescents.

    Patients with sickle cell disease have an amplified vulnerability to urinary tract infection, because of abnormally dilute and alkaline urine, which favors bacterial proliferation. This is due to altered blood flow in the renal vasculature, which causes papillary necrosis and loss of urinary concentrating and acidifying ability of the nephrons. Asymptomatic bacteriuria is common, but the prevalence in populations varies widely with age, gender, sexual activity and the presence of genitourinary abnormalities. The aim of this study was to determine the prevalence of significant bacteriuria in symptomatic and asymptomatic sickle cell patients in Lagos. This was a cross-sectional study of patients attending the sickle cell clinics of Lagos State University Teaching Hospital, Ikeja. Single voided aseptically collected mid-stream urine was obtained from each patient and all samples processed immediately, were sent for urinalysis and culture. Isolates were considered significant if there were ≥10 5 colony forming units per milliliter (CFU/ml) with two or less isolates, doubtful significance if ≤10 5 CFU/ml. Significant isolates were selected for identification. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 16.0 (SPSS, Inc., Chicago, Ill). A total of 100 consenting participants were recruited into the study. The mean age was: 23.42 ± 8.31 years and a range of 14-50 years. Only 9% (9/100) had significant bacteriuria while 44.4% (4/9) participants who had significant bacteriuria were asymptomatic. Escherichia coli was isolated in 66.6% (6/9) participants who had significant bacteriuria while Klebsiella oxytoca, Klebsiella pneumonia and Staphylococcus aureus (11.11%) was isolated in each of the remaining three participants. Significant bacteriuria is found in only one-tenth of sickle cell patients, nearly half of the participants who had significant growth had asymptomatic bacteriuria.

    National surveillance data from 2006 to 2010 of the Dutch sexually transmitted infection (STI) centres were used to analyse current practices on testing extragenital sites for chlamydia and gonorrhoea in men who have sex with men (MSM) and women. In MSM, 76.0% and 88.9% were tested at least at one extragenital site (pharyngeal and/or anorectal) for chlamydia and gonorrhoea, respectively; for women this was 20.5% and 30.2%. Testing more than one anatomic site differed by STI centre, ranging from 2% to 100%. In MSM tested at multiple sites, 63.0% and 66.5% of chlamydia and gonorrhoea diagnoses, respectively, would have been missed if screened at the urogenital site only, mainly anorectal infections. For women tested at multiple sites, the proportions of missed chlamydia and gonorrhoea diagnoses would have been 12.9% and 30.0%, respectively. Testing extragenital sites appears warranted, due to the numerous infections that would have been missed. Adding anorectal screening to urogenital screening for all MSM visiting an STI centre should be recommended. Since actual testing practices differ by centre, there is a need for clearer guidelines. Routine gonorrhoea and chlamydia screening at multiple sites in STI centres should be investigated further as this might be a more effective approach to reduce transmission than current practice.

    Chronic asymptomatic elevation of pancreatic enzymes is a well known entity although little has been reported. In most cases chronic asymptomatic elevation of amylase is due to a salival isoamylase increase or macroamylasemia. However, we have studied 10 cases with an increase in amylases due to pancreatic isoamylase and an increase in the remaining pancreatic enzymes which remained elevated during the follow up period ranging from 2 to 60 months. The amylase values ranged from 186 to 1,600; the lipase from 176 to 3,989, trypsin from 476 to 2,430 and pancreatic isoamylase from 122 to 1,263. In all patients CT and echography were carried out, which discarded structural damage. Nonetheless, an indirect test of pancreatic function presented unexplained pathologic values in 4 out of 10 patients. In conclusion, we suggest that chronic asymptomatic elevation of pancreatic enzymes is of unknown etiology with no associated structural pancreatic pathology demonstrable by the usual study methods.

    Inadequacy of collateral arterial flow is the major risk factor for hemispheric infarction in association with spontaneous occlusion of the ipsilateral carotid artery. This prospective study was designed to measure the adaptation of collateral cerebral circulation through the circle of Willis in patients in whom a unilateral carotid stenosis of hemodynamic consequence develops asymptomatically. The collateral cerebral potential is assessed by ocular pneumoplethysmography (OPG) during proximal common carotid artery compression, measuring the collateral ophthalmic artery pressure (COAP). During an average follow-up of almost 3 years (maximum more than 7 years), 45 patients showed asymptomatic development of a unilateral hemodynamically significant carotid stenosis according to OPG evidence. In these patients the mean index COAP/brachial artery pressure did not change on the side of stenosis progression (p greater than 0.05). The developed carotid stenosis had only reduced collateral circulation to the contralateral hemisphere. The risk of inadequate collateral cerebral circulation remained during progression of asymptomatic extracranial arterial obstructive disease.

    Objective To determine the prevalence of asymptomatic bacteriuria, bacteriology and sensitivity pattern in Ilorin using the gold standard of urine culture. Methods A prospective study was carried out from 1st July to 31st October 2007, at the University of Ilorin Teaching Hospital (UITH) on 125 consenting asymptomatic pregnant women. A structured proforma was used to collect information from the women and a midstream urine specimen collected for bacteriological culture. Results Of the 125 pregnant women, 50 had bacteriuria on urine culture giving a prevalence of 40%. The mean age of the women was 28.5 years with a standard deviation of 4.95. The age ranged between 14 and 40 years. Staphylococcus aureus was the commonest pathogen isolated (72%), followed by Proteus spp (14%). Most of the organisms showed good sensitivity to Nitrofurantoin and gentamicin. Conclusion The prevalence of asymptomatic bacteriuria in Ilorin is high and routine urine culture is advocated for all pregnant women at booking. PMID:22359722

    A Cochrane systematic review has shown that drug treatment of asymptomatic bacteriuria in pregnant women substantially decreases the risk of pyelonephritis and reduces the risk of preterm delivery. However, it is not clear whether single-dose therapy is as effective as longer conventional antibiotic treatment. To assess the effects of different durations of treatment for asymptomatic bacteriuria in pregnancy. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 August 2011) and reference lists of identified articles. Randomized and quasi-randomized trials comparing antimicrobial therapeutic regimens that differed in duration (particularly comparing single dose with longer duration regimens) in pregnant women diagnosed with asymptomatic bacteriuria. We assessed trial quality and extracted data independently. We included 13 studies, involving 1622 women. All were comparisons of single-dose treatment with four- to seven-day treatments. The trials were generally of limited quality. The 'no cure rate' for asymptomatic bacteriuria in pregnant women was slightly higher for the single-dose than for the short-course treatment; however, these results were not statistically significant and showed heterogeneity. When comparing the trials that used the same antibiotic in both treatment and control groups with the trials that used different antibiotics in both groups, the 'no cure rate' risk ratio was similar. There was no statistically significant difference in the recurrence of asymptomatic bacteriuria rate between treatment and control groups. Slight differences were detected for preterm births and pyelonephritis although, apart from one trial, the sample size of the trials was inadequate. Single-dose treatment was associated with a decrease in reports of 'any side-effects' . Single-dose regimen of antibiotics may be less effective than the seven-day regimen. Women with asymptomatic bacteriuria in pregnancy should be treated by the standard regimen of

    This study was done to determine whether erythroid alterations can be found on a peripheral blood smear from an asymptomatic person exposure to excess atmospheric lead. Thirty healthy, asymptomatic adults who lived within five miles of a major Los Angeles, California freeway for five consecutive years were studied. Erythroid cytologic alterations-including-anisocytosis, poikilocytosis, polychromasia and basophilic stippling were statistically associated with increased free erythrocyte protoporphyrin levels. These findings indicate that erythroid alterations may be found on a peripheral blood smear prior to the development of clinical symptoms of lead intoxication.

    This article discusses the merits of electrophysiology study (EPS) and/or ablation for asymptomatic preexcitation Wolff-Parkinson-White (WPW) ECG pattern. Sudden deaths in asymptomatic patients are too few to merit broad screening and aggressive intervention. It also discusses the risks of ablation and the low predictive accuracy of EPS. When WPW is an incidental finding, the decision to proceed with investigation and ablation can be made considering patients' situations and preferences. An invasive strategy is targeted at patients concerned about the low risk of life-threatening arrhythmia as a first presentation after a discussion of the risks and benefits.

    Aortic stenosis (AS) is a disease that progresses slowly for years without symptoms, so patients need to be carefully managed with appropriate follow up and referred for aortic valve replacement in a timely manner. Development of symptoms is a clear indication for aortic valve intervention in patients with severe AS. The decision for early surgery in patients with asymptomatic severe AS is more complex. In this review, we discuss how to identify high-risk patients with asymptomatic severe AS who may benefit from early surgery. PMID:26981214

Twelve patients (57.1%) in group 1 and 13 patients (50%) in group 2 were scored above 9 points of Cleveland Clinic Incontinence Score, which is the reference value for fecal incontinence (P = 0.770). With time, there was a significant difference (P = 0.002) in the change of mean resting pressure according to time sequence between the BFT and control groups.BFT during the temporary stoma interval had no effect on preventing anorectal dysfunction after temporary stoma reversal at 6 months after rectal resection. However, BFT might be helpful for maintaining resting anal sphincter tone (NCT01661829).

    Chlamydia trachomatis and Neisseria gonorrhoeae are 2 very common sexually transmitted organisms, whose clinical manifestations in women can range from an asymptomatic carrier state to active pelvic inflammatory disease with known serious sequelae, including chronic pelvic pain, infertility, and ectopic pregnancy. The economic and clinical burden of these 2 infectious organisms are significant in the sexually active population. New developments in diagnosis and treatment of these infections raise great hope that substantial reduction in morbidity and disease prevalence rates can be achieved. Herpes simplex virus is probably better publicized and more feared in the sexually active population, and is far more prevalent than previously recognized; fortunately, however, it is not generally associated with significant morbidity. This article will review the current diagnoses and treatments of these conditions and consider some of the issues surrounding the impact of screening asymptomatic sexually active individuals. The treatment guidelines will emphasize the 1998 Guidelines for Treatment of Sexually Transmitted Diseases from the Centers for Disease Control and Prevention.

The specific topics briefly discussed are incidence, psychological impact, assault assessment kits, medical evaluation, legal concerns, counseling, follow-up, and special circumstances. It is stated that a woman who is sexually assaulted would experience intense anxiety, anger or fear, and rape-trauma syndrome. The physician evaluating the victim should be aware of the state statutory requirements, which may involve the use of kits for gathering evidence. Informed consent from the victim and meticulous physical examination of the entire body should be performed with photographs and drawings made in the injured areas. In counseling, the physician should talk with the patient concerning the degree of the injury and the probability of infection or pregnancy. There is a need for patients to be reevaluated concerning her medical and psychological status.

    This article is part of a Special Issue "Puberty and Adolescence". Sexuality emerges as a major developmental element of puberty and the adolescent years that follow. However, connecting the sexuality that emerges with puberty and elements of adult sexuality is difficult because much adolescent sexuality research addresses the transition to partnered sexual behaviors (primarily coitus) and consequences such as unplanned pregnancy and sexually transmitted infections. This review proposes a framework of an expanded understanding of puberty and adolescent sexuality from the perspective of four hallmarks of adult sexuality: sexual desire; sexual arousal; sexual behaviors; and, sexual function. This approach thus addresses important gaps in understanding of the ontogeny of sex and the continuum of sexuality development from adolescence through the adult lifespan.

    Summary Background Whether surgery is beneficial for patients with asymptomatic carotid stenosis is controversial. Better methods of identifying patients who are likely to develop stroke would improve the risk–benefit ratio for carotid endarterectomy. We aimed to investigate whether detection of asymptomatic embolic signals by use of transcranial doppler (TCD) could predict stroke risk in patients with asymptomatic carotid stenosis. Methods The Asymptomatic Carotid Emboli Study (ACES) was a prospective observational study in patients with asymptomatic carotid stenosis of at least 70% from 26 centres worldwide. To detect the presence of embolic signals, patients had two 1 h TCD recordings from the ipsilateral middle cerebral artery at baseline and one 1 h recording at 6, 12, and 18 months. Patients were followed up for 2 years. The primary endpoint was ipsilateral stroke and transient ischaemic attack. All recordings were analysed centrally by investigators masked to patient identity. Findings 482 patients were recruited, of whom 467 had evaluable recordings. Embolic signals were present in 77 of 467 patients at baseline. The hazard ratio for the risk of ipsilateral stroke and transient ischaemic attack from baseline to 2 years in patients with embolic signals compared with those without was 2·54 (95% CI 1·20–5·36; p=0·015). For ipsilateral stroke alone, the hazard ratio was 5·57 (1·61–19·32; p=0·007). The absolute annual risk of ipsilateral stroke or transient ischaemic attack between baseline and 2 years was 7·13% in patients with embolic signals and 3·04% in those without, and for ipsilateral stroke was 3·62% in patients with embolic signals and 0·70% in those without. The hazard ratio for the risk of ipsilateral stroke and transient ischaemic attack for patients who had embolic signals on the recording preceding the next 6-month follow-up compared with those who did not was 2·63 (95% CI 1·01–6·88; p=0·049), and for ipsilateral stroke

    From a cohort study of homosexual men in Amsterdam, 61 human immunodeficiency virus (HIV)-infected men who had remained asymptomatic for at least 7 years were identified. In a nested case control study, these men were compared with 142 men who progressed symptomatic HIV infection (CDC class IV) within 7 years, regarding laboratory markers, sexual behavior, psychologic coping, and drug use. Of the 61 long-term asymptomatic men, 13 had a CD4+ cell count > or = 500/mm3 after 7 years; in 2 of these 13, the CD4+ cell count had not declined during follow-up. Independent of CD4+ cell count, long-term asymptomatic HIV-1 infection was characterized by stable T cell reactivity after stimulation with monoclonal CD3 antibodies, seropositivity for antibodies to HIV core proteins, and the absence of hepatitis B markers. No association with markers of high-risk sex or the recreational use of drugs was found. Long-term asymptomatic men had a slightly lower score regarding the coping behavior active problem-solving; no other associations with coping behaviors were found.

    Physiological or non-physiological factors may affect the vaginal flora. The occurrence of genital microorganisms in non-pregnant females of all ages was studied, as were the risk factors associated with each microorganism. A retrospective analysis of vaginal and endocervical cultures and wet smears from 27,172 non-pregnant women, between 1996 to 2005, was performed taking into consideration clinical and socio-demographic characteristics. No microorganisms were observed in 55.7% of the individuals studied and 44.3% had positive cultures. There was no microbiological aetiology in 49% of women with genital symptoms. Poor hygiene, chemical irritants, sexual behaviour, vaginal blood, birth control type, and/or the lack of an oestrogen effect may have caused the symptoms. The highest occurrence of Gram-negative bacteria (p<0.01), mainly Escherichia coli, was observed in prepubescent girls. The highest occurrence of Candida species (p<0.01) was in women of childbearing age, and of Gram-positive bacteria (p<0.01) in menopausal women. Adolescents, particularly asymptomatic girls, carried more frequently Ureaplasma urealyticum and Chlamydia trachomatis (p<0.01). Hormonal contraception and consistent condom use was protective against bacterial vaginosis and U. urealyticum colonization. Users of intrauterine devices had an increased risk of bacterial vaginosis or of contracting U. urealyticum, Mycoplasma hominis and Candida species. Genital complaints were an independent indicator of Candida species, Gram-negative and Gram-positive bacteria, Trichomonas vaginalis and bacterial vaginosis.Chlamydia trachomatis infections were often asymptomatic. It is concluded that the hormonal milieu and non-physiological factors are major determinants of the vaginal flora. If diagnosis of genital infections is based on symptoms alone and not on culture results, it may be erroneous. Sexual abuse should be investigated when a child presents with a sexually transmitted disease.

    Despite the public health importance of giardiasis in all of Europe, reliable data on the incidence and prevalence in Western Balkan Countries (Serbia, Bosnia and Herzegovina, Croatia, Montenegro and FYR Macedonia) are scarce, and the relative contribution of waterborne and food-borne, or person-to-person and/or animal-to-person, transmission of human giardiasis is not yet clear. To provide baseline data for the estimation of the public health risk caused by Giardia, we here review the information available on the epidemiological characteristics of asymptomatic and symptomatic human infection in Serbia. Although asymptomatic cases of Giardia represent a major proportion of the total cases of infection, high rates of Giardia infection were found in both asymptomatic and symptomatic populations. No waterborne outbreaks of giardiasis have been reported, and it thus seems that giardiasis mostly occurs sporadically in our milieu. Under such circumstances, control measures to reduce the high prevalence of giardiasis in Serbia have focused on person-to-person transmission, encouraging proper hygiene, but for more targeted intervention measures, studies to identify other risk factors for asymptomatic and symptomatic infections are needed.

    To investigate the prevalence and risk factors of asymptomatic colorectal diverticulosis in Taiwanese general population. From January 2009 to December 2011, consecutive asymptomatic subjects undergoing a health check-up were evaluated by colonoscopy. The colorectal diverticulosis was assessed, and a medical history and demographic data were obtained from each subject. Logistic regression analysis was conducted to search the risk factors of colorectal diverticulosis. Of the 1899 asymptomatic subjects, the prevalence of colorectal diverticulosis was 13.5%. On univariate logistic regression analysis, age over 60 years old, male, adenomatous polyp, current smoking and heavy alcohol consumption were significantly associated with diverticulosis. Multivariate logistic regression analysis revealed that age over 60 years old (relative risk [RR], 2.57; 95% confidence interval [CI], 1.64-6.47), adenomatous polyps (RR, 2.18; 95% CI, 1.18-4.61) and heavy alcohol consumption (RR, 1.82; 95% CI, 1.04-3.08) were independent predictors for colorectal diverticulosis. The prevalence of asymptomatic colorectal diverticulosis was 13.5% in Taiwan. Age over 60 years old, adenomatous polyp and heavy alcohol consumption may affect the risk of development of the disease.

    This audit aimed to determine the usefulness of microscopy to detect presumptive rectal gonorrhoea (GC) infection in asymptomatic men. We retrospectively audited more than 400 male patients attending a London genitourinary medicine clinic from January 2005 to March 2007 who tested rectal culture positive for Neisseria gonorrhoeae and compared this with the microscopy detection rate. In total, 123/423 (29%) of culture positive samples were microscopy positive. Of those that tested microscopy negative (300/423), 64 (21%) were symptomatic and 236 (79%) asymptomatic. In addition, a time and motion study examined 81 rectal slides over a two-week period to identify microscopy reading time required to make a presumptive diagnosis of GC. Three slides were positive, resulting in six hours and 45 minutes to detect one positive sample. Given the low sensitivity for rectal microscopy coupled with the length of time required to obtain a presumptive positive rectal GC result, we believe rectal microscopy is no longer a cost-effective tool screening for asymptomatic men, and this report supports the BASHH guideline that it is not recommended in the management of asymptomatic rectal infection.

    Patients with primary hyperparathyroidism (PHP), even asymptomatic, have an increased cardiovascular risk. However, data on reversibility or improvement of cardiovascular disorders with surgery are controversial. Our aims were to assess the prevalence of classic cardiovascular risk factors in patients with asymptomatic PHP, to explore their relationship with calcium and PTH levels, and analyze the effect of parathyroidectomy on those cardiovascular risk factors. A retrospective, observational study of two groups of patients with asymptomatic PHP: 40 patients on observation and 33 patients who underwent surgery. Clinical and biochemical data related to PHP and various cardiovascular risk factors were collected from all patients at baseline and one year after surgery in the operated patients. A high prevalence of obesity (59.9%), type 2 diabetes mellitus (25%), high blood pressure (47.2%), and dyslipidemia (44.4%) was found in the total sample, with no difference between the study groups. Serum calcium and PTH levels positively correlated with BMI (r=.568, P=.011, and r=.509, P=.026 respectively) in non-operated patients. One year after parathyroidectomy, no improvement occurred in the cardiovascular risk factors considered. Our results confirm the high prevalence of obesity, type 2 diabetes mellitus, high blood pressure, and dyslipidemia in patients with asymptomatic PHP. However, parathyroidectomy did not improve these cardiovascular risk factors. Copyright © 2014 SEEN. Published by Elsevier Espana. All rights reserved.

    To evaluate the appearance of the plantar fascia in asymptomatic subjects. Thirty-one asymptomatic subjects were examined by 2 musculoskeletal radiologists. The plantar fascia was evaluated for thickness, echogenicity, vascularity on power Doppler, rupture, fluid adjacent to the fascia, andcalcifications. The study included 14 men and 17 women (age, 17-79 years; mean, 45 years). The mean thickness of the plantar fascia in men was 3.7 mm (range 2.5-7 mm), and in women 3.5 mm (range, 1.7-5.1 mm). The thickness was greater than 4 mm in 4 men (bilateral in 2). The mean thickness of fascias thicker than 4 mm in men was 5.4 mm (range, 4.3-7 mm). The thickness was greater than 4 mm in 5 women ( bilateral in 4). The mean thickness of fascias thicker than 4 mm in women was 4.7 mm (range, 4.2-5.1 mm). There was no statistically significant difference between men and women and between both heels. Hypoechogenicity was observed in 3 men (bilateral in 2), and in 5 women (bilateral in 6). Hypervascularity, rupture, fluid adjacent to the fascia, and calcifications were not observed. A thickness greater than 4 mm and hypoechogenicity, are common in the plantar fascia of asymptomatic subjects. Findings that were not seen in asymptomatic subjects include a thickness greater than 7 mm, hypervascularity on power Doppler, rupture, fluid adjacent to the fascia, and calcifications.

    Parasitic diseases suppose an important health problem in people from high endemic areas, so these must be discarded properly. Usually, these infections develop asymptomatically but, in propitious situations, are likely to reactivate themselves and can cause clinical symptoms and/or complications in the receiving country. Moreover, in some cases it is possible local transmission. Early diagnosis of these parasitic diseases made by appropriate parasitological techniques and its specific treatment will benefit both, the individual and the community. These techniques must be selected according to geoepidemiological criteria, patient's origin, migration route or time spent outside the endemic area; but other factors must also be considered as its sensitivity and specificity, implementation experience and availability. Given the high prevalence of intestinal parasites on asymptomatic immigrants, it is recommended to conduct a study by coproparasitological techniques. Because of its potential severity, the screening of asymptomatic malaria with sensitive techniques such as PCR (polymerase chain reaction) is also advisable. Serological screening for Chagas disease should be performed on all Latin American immigrants, except for people from the Caribbean islands. Other important parasites, which should be excluded, are filariasis and urinary schistosomiasis, by using microscopic examination. The aim of this paper is to review the different techniques for the screening of parasitic diseases and its advices within the care protocols for asymptomatic immigrants.

    The mycotoxin deoxynivalenol (DON) elicits robust anorectic and emetic effects in several animal species. However, less is known about the potential for naturally occurring and synthetic congeners of this trichothecene to cause analogous responses. Here we tested the hypothesis that alterations in DON structure found in the plant metabolite deoxynivalenol-3-glucoside (D3G) and two pharmacologically active synthetic DON derivatives, EN139528 and EN139544, differentially impact their potential to evoke food refusal and emesis. In a nocturnal mouse food consumption model, oral administration with DON, D3G, EN139528, or EN139544 at doses from 2.5 to 10 mg/kg BW induced anorectic responses that lasted up to 16, 6, 6, and 3 h, respectively. Anorectic potency rank orders were EN139544>DON>EN139528>D3G from 0 to 0.5 h but DON>D3G>EN139528>EN139544 from 0 to 3 h. Oral exposure to each of the four compounds at a common dose (2.5 mg/kg BW) stimulated plasma elevations of the gut satiety peptides cholecystokinin and to a lesser extent, peptide YY3–36 that corresponded to reduced food consumption. In a mink emesis model, oral administration of increasing doses of the congeners differentially induced emesis, causing marked decreases in latency to emesis with corresponding increases in both the duration and number of emetic events. The minimum emetic doses for DON, EN139528, D3G, and EN139544 were 0.05, 0.5, 2, and 5 mg/kg BW, respectively. Taken together, the results suggest that although all three DON congeners elicited anorectic responses that mimicked DON over a narrow dose range, they were markedly less potent than the parent mycotoxin at inducing emesis.

    The search for drugs with anorectic activity, acting within the adrenergic system has attracted the interest of researchers. Partial α2-adrenoceptor agonists might offer the potential for effective and safe treatment of obesity. We compared the effectiveness and safety of α2-adrenoceptor ligands in reducing body mass. We also analyzed if antagonist and partial agonists of α2-adrenoceptor––yohimbine and guanfacine––act similarly, and determined which course of action is connected with anorectic activity. We tested intrinsic activity and effect on the lipolysis of these compounds in cell cultures, evaluated their effect on meal size, body weight in Wistar rats with high-fat diet-induced obesity, and determined their effect on blood pressure, heart rate, lipid profile, spontaneous locomotor activity, core temperature and glucose, as well as glycerol and cortisol levels. Both guanfacine and yohimbine showed anorectic activity. Guanfacine was much more effective than yohimbine. Both significantly reduced the amount of intraperitoneal adipose tissue and had a beneficial effect on lipid profiles. Decreased response of α2A-adrenoceptors and partial stimulation of α2B-receptors seem to be responsible for the anorectic action of guanfacine. The stimulation of α1-adrenoceptors by guanfacine is responsible for cardiovascular side effects but may also be linked with improved anorexic effect. α1-adrenoceptor blockade is connected with the side effects of yohimbine, but it is also associated with the improvement of lipid profiles. Guanfacine has been approved by the Food and Drug Administration (FDA) to treat hypertension and conduct disorder, but as it reduces body weight, it is worth examining its effectiveness and safety in models of obesity.

    The mechanisms of increased rectal stiffness in women with fecal incontinence (FI) and rectal urgency are not understood. Our hypothesis was that distention-induced activation of mechanosensitive L-type calcium channels in smooth muscle contributes to increased rectal stiffness in FI. Anal pressures, rectal distensibility (compliance, capacity, and contractile response to sinusoidal oscillation), and rectal sensation were assessed before and after oral nifedipine (30 + 10 mg) or placebo in 16 women with FI and 16 asymptomatic women. At baseline, FI patients had a lower anal pressure increment during squeeze (health, 66.9 ± 7.6: FI, 28.6 ± 5.9, mean ± SE, P ≤ 0.01), lower rectal capacity (P = 0.052), and higher rectal pressures during sinusoidal oscillation (health, 13.7 ± 3.2: FI, 21.7 ± 1.4, mean ± SE, P = 0.02) than the healthy women, which suggests an exaggerated rectal contractile response to distention. Nifedipine decreased mean BP, increased heart rate (P = 0.01 vs. placebo), and reduced anal resting pressure (P ≤ 0.01) but did not significantly modify rectal distensibility in health or FI. Plasma nifedipine concentrations (health, 103 ± 21 ng/ml: FI, 162 ± 34 ng/ml) were correlated with increased rectal compliance (r = 0.6, P = 0.02) in all study participants and, in healthy subjects, with decreased rectal pressures during sinusoidal oscillation (r = 0.86, P = 0.01), indicative of reduced stiffness. No consistent effects on rectal perception were observed. These observations confirm that FI is associated with anal weakness and increased rectal stiffness. At therapeutic plasma concentrations, nifedipine reduced anal resting pressure but did not improve rectal distensibility in FI, outcomes that argue against a predominant contribution of myogenic L-type calcium channels to reduced rectal distensibility in FI.

    Patients with autoimmune hepatitis (AIH) can present with symptoms ranging from those that are insidious and nonspecific to acute hepatitis with jaundice. However, some patients have no symptoms at diagnosis and are identified incidentally. We investigated disease progression and outcomes of these 2 groups of patients. We performed a retrospective study to compare clinical, immunologic, and histologic features and outcomes of patients with asymptomatic vs. symptomatic AIH. We analyzed data collected from 305 patients (90 asymptomatic and 215 with symptoms), diagnosed with AIH from 1994 and 2013, at the Center for the Study and Treatment of the Autoimmune Diseases of the Liver and Biliary System in Bologna, Italy. At diagnosis, patients with asymptomatic AIH had significantly lower mean levels of alanine aminotransferase (7.0- ± 8.0-fold the upper limit of normal) than patients with symptomatic disease (23.0- ± 18.0-fold the upper limit of normal; P < .001), and lower mean levels of bilirubin (1.4 ± 1.4 mg/dL vs. 8.6 ± 10.4 mg/dL; P < .001). Asymptomatic patients also had significantly lower histologic grades (7.0 ± 2.5) than symptomatic patients (9.0 ± 2.9; P < .001). However, larger proportions of asymptomatic patients had anti-liver/kidney microsomal antibodies type 1 (26.8% vs. 13.1%; P < .006), and associated autoimmune thyroid (26.7% vs. 12.6%; P = .003) or skin (8.9% vs. 2.3%; P = .010) disorders. Age at onset, sex, response to therapy, disease progression, genetic factors, and other autoantibody markers did not differ between patients with asymptomatic vs. symptomatic disease. Patients with asymptomatic vs. symptomatic AIH have similar courses of disease progression and responses to immunosuppressive agents, and therefore should receive the same treatment. Patients affected by thyroid or dermatologic autoimmune disorders are at increased risk of developing subclinical liver disease, and should be assessed routinely for AIH. Copyright © 2016 AGA

    Background Physicians do not routinely recommend smokers to undergo spirometry unless they are symptomatic. Objective To test the hypothesis that there are a significant number of asymptomatic smokers with chronic obstructive pulmonary disease (COPD), we estimated the prevalence of COPD in a group of asymptomatic smokers. Methods Two thousand nine hundred and sixty-one smokers with a cumulative consumption history of at least 10 pack-years, either smokers with symptoms or smokers without symptoms (WOS) were invited to perform a spirometry and complete a symptom questionnaire. Results Six hundred and thirty-seven (21.5%) smokers had no symptoms, whereas 2,324 (78.5%) had at least one symptom. The prevalence of COPD in subjects WOS was 1.5% when considering the whole group of smokers (45/2,961) and 7% when considering only the group WOS (45/637). From 329 smokers with COPD, 13.7% were WOS. Subjects WOS were younger, had better lung function and lower cumulative consumption of cigarettes, estimated as both cigarettes per day and pack-years. According to severity of airflow limitation, 69% vs 87% of subjects were classified as Global Initiative for Chronic Obstructive Lung Disease stages I–II in the WOS and smokers with symptoms groups, respectively (P<0.001). A multivariate analysis showed that forced expiratory volume in 1 second (mL) was the only predictive factor for COPD in asymptomatic smokers. Conclusion Prevalence of COPD in asymptomatic smokers is 1.5%. This number of asymptomatic smokers may be excluded from the benefit of an “early” intervention, not just pharmacological but also from smoking cessation counseling. The higher forced expiratory volume in 1 second may contribute to prevent early diagnosis. PMID:26586941

    Until a short time ago, hydatidosis was considered a pathology that could only be resolved surgically. However, in recent years progress has been made with the epidemiology, diagnosis, and treatment of the disease, and new information on the natural history of hydatidosis has helped define new criteria for its treatment. It is now known that as many as 67% of the carriers of liver cysts who are asymptomatic remain so throughout their lives. This situation produces special results in immunologic testing. Enzyme-linked immunosorbent assay (ELISA) has a sensitivity of 63% and a specificity of 97% with asymptomatic carriers, while the double diffusion arc 5 test (DD5) achieves a sensitivity of only 31% with the same population. On the other hand, imaging studies based on ultrasonography have become the method of choice to detect asymptomatic carriers. Ultrasonography studies are 49% to 73% more sensitive than serological tests, and they can even be used as a part of epidemiological surveillance systems and to monitor control programs. Treatment schemes have also been modernized. Treating asymptomatic carriers chemotherapeutically with albendazole produces favorable results in as many as 69% of cases, while such minimally invasive surgical treatments as puncture-aspiration-injection-reaspiration (PAIR) reduce average cyst volume by as much as 66%. These factors have made it possible for hospital services in the province of Río Negro, Argentina, to establish a treatment scheme for asymptomatic carriers. It is based on the monitoring of small cysts (type Ia on the modified Gharbi scale); initial treatment with albendazole, followed by PAIR if there is no response, in larger or more complex cysts (types Ib, II, and III); and follow-up of inviable or dead cysts (types IV and V).

    A Cochrane systematic review has shown that drug treatment of asymptomatic bacteriuria in pregnant women substantially decreases the risk of pyelonephritis and reduces the risk of preterm delivery. However, it is not clear whether single dose therapy is as effective as longer conventional antibiotic treatment. The objective of this review was to assess the effects of different durations of treatment for asymptomatic bacteriuria in pregnancy. We searched the Cochrane Pregnancy and Childbirth Group trials register, the Cochrane Controlled Trials Register and the reference lists of articles. Randomised and quasi-randomised trials comparing antimicrobial therapeutic regimens that differed in duration (particularly comparing single dose with longer duration regimens) in pregnant women diagnosed with asymptomatic bacteriuria. Trial quality was assessed and data were extracted independently by the reviewers. Eight studies involving over 400 women were included. All were comparisons of single dose treatment with four to seven day treatments. The trials were generally of poor quality. No difference in 'no-cure' rate was detected between single dose and short course (4-7 day) treatment for asymptomatic bacteriuria in pregnant women (relative risk 1.13, 95% confidence interval 0.82 to 1.54) as well as in the recurrent asymptomtic bacteriuria (relative risk 1.08, 95% confidence interval 0.70 to 1.66). However these results showed significant heterogeneity. No differences were detected for preterm births and pyelonephritis although sample size of trials was small. Longer duration treatment was associated with an increase in reports of adverse effects (relative risk 0.53, 95% confidence interval 0.31 to 0.91). There is not enough evidence to evaluate whether single dose or longer duration doses are more effective in treating asymptomatic bacteriuria in pregnant women. Because single dose has lower cost and increases compliance, this comparison should be explored in a properly

    Wolff-Parkinson-White (WPW) pattern is occasionally found in asymptomatic aviators during routine ECGs. Aeromedical concerns regarding WPW pattern include risk of dysrhythmia or sudden cardiac death (SCD), thus affecting the safety of flight. The purpose of this study was to determine the prevalence and outcomes of aviators with asymptomatic WPW pattern and assess for risk factors that contribute to progression to dysrhythmia or symptoms. The U.S. Air Force (USAF) ECG library database containing over 1.2 million ECGs collected over the past 68 yr was used to identify 638 individual aviators with WPW pattern. Demographic, medical history, and outcome data were obtained by medical record review. Aviators who developed high risk features defined as symptoms, arrhythmia, or ablation of a high risk pathway, were compared to those who remained asymptomatic. Prevalence of WPW pattern was 0.30% among all USAF aviators. Of the 638 individuals, 64 (10%) progressed to the combined endpoint of SCD, arrhythmia, and/or ablation of a high risk pathway over 6868 patient years, with average follow-up of 10.5 yr. There were two sudden cardiac deaths (0.3%). Annual risk of possible sudden incapacitation was 0.95% and of SCD 0.03%. Those that progressed to high risk were significantly younger, had lower diastolic blood pressure, lower total cholesterol, and better physical fitness testing scores. WPW pattern on ECG found in asymptomatic aviators confers < 1% annual risk of arrhythmia or incapacitating events with the highest risk in the younger, healthier, and most fit populations.Davenport ED, Rupp KAN, Palileo E, Haynes J.

    The role for c-Jun N-terminal Kinase (JNK) in the control of feeding and energy balance is not well understood. Here, by use of novel and highly selective JNK inhibitors, we investigated the actions of JNK in the control of feeding and body weight homeostasis. In lean mice, intraperitoneal (i.p.) or intracerebroventricular (i.c.v.) administration of SR-3306, a brain-penetrant and selective pan-JNK (JNK1/2/3) inhibitor, reduced food intake and body weight. Moreover, i.p. and i.c.v. administrations of SR11935, a brain-penetrant and JNK2/3 isoform-selective inhibitor, exerted similar anorectic effects as SR3306, which suggests JNK2 or JNK3 mediates aspect of the anorectic effect by pan-JNK inhibition. Furthermore, daily i.p. injection of SR3306 (7 days) prevented the increases in food intake and weight gain in lean mice upon high-fat diet feeding, and this injection paradigm reduced high-fat intake and obesity in diet-induced obese (DIO) mice. In the DIO mice, JNK inhibition sensitized leptin’s anorectic effect, and enhanced leptin-induced STAT3 activation in the hypothalamus. The underlying mechanisms likely involve the downregulation of SOCS3 by JNK inhibition.

    Anorectal malformations encompass a broad spectrum of congenital defects and are related to the development of the genital tubercle, including the cloacal plate and urorectal septum. To explore the cellular and molecular basis of anorectal malformations, we analyzed the pathogenetic process using two mouse models: Danforth's short tail (Sd) and all-trans retinoic acid (ATRA)-treated mice. Embryologically, the cloacal plate may be divided into distal and proximal parts, with the distal part subdivided into ventral and dorsal parts. In the two mouse models, anorectal malformations occur due to improper development of the proximal part of the cloacal plate. At 10.5 days postcoitus (dpc), in Sd homozygotes, there was a lack of Shh expression only in the cloacal plate and the endoderm around the cloacal plate. In addition, Wnt5a was not expressed in the mesoderm adjacent to the cloacal plate in the two mouse models, and Axin2, which is regulated by Wnt signaling, was not expressed in the dorsal part of the cloacal plate at 12.5 dpc. Based on these results, we suggest that Wnt5a, which is downstream of Shh signaling, and Axin2 affect the development of the proximal part of the cloacal plate.

    Abstract Background: Lymph nodes and gut-associated lymphatic tissue are important reservoirs of the human immunodeficiency virus (HIV). Little is known about these reservoirs in different geographic populations. We report the surgical outcomes of excisional lymph node and anorectal mucosal biopsies performed internationally and describe the lessons learned. Methods: Patients were recruited through the Joint Clinical Research Center (JCRC) in Kampala, Uganda, where procedures were performed. Studies were approved by the Institutional Review Boards of the JCRC and the University of Minnesota. Instruments and supplies were shipped to Uganda and prepared onsite. Drugs and skin preparations were purchased locally. Lymph nodes were removed through 1–3 cm incisions with ligatures on lymphovascular pedicles. Incisions were closed with subcuticular sutures and epidermal tape. Two to four pieces of anorectal mucosa were obtained through anoscopes using biopsy forceps. Results: One hundred thirty-eight lymph node biopsies and 98 anorectal mucosal biopsies were performed on 71 patients. Forty-one patients were HIV-positive. Many patients had multiple procedures. Two minor complications resulted: One hematoma and one lymphocele. Despite the cost of travel and lodging, cost per biopsy was lower in Uganda compared with the United States. Conclusion: Invasive clinical research can be performed with minimal morbidity in emerging nations with outcomes similar to those found in the United States, but with lower cost. PMID:25650809

    PubMed

    2011-01-01

    Sexually transmitted infections (STI) include a group of diseases of diverse infectious etiology in which sexual transmission is relevant. The burden of disease that STI represent globally is unknown for several reasons. Firstly, asymptomatic infections are common in many STI; secondly, diagnostic techniques are not available in some of the most affected countries; finally, surveillance systems are inexistent or very deficient in many areas of the world. The Word Health Organization has estimated that in 1999 there were 340 million new cases of syphilis, gonorrhoea, chlamydia infection and trichomoniasis. An increasing trend in the incidence of gonorrhoea and syphilis has been noticed in the last years in the European Union, including Spain. Co-infection with other STI, especially HIV, should be ruled out in all STI patients. Chlamydia screening is also of particular importance since this is the most common STI in Europe and frequently goes unnoticed. STI prevention and control should be based on health education, early diagnosis and treatment, screening for asymptomatic infections, contact investigation and vaccination for those diseases for which a vaccine is available.

    Chronic idiopathic constipation (IC) is a common problem in children. We hypothesised that hypertonicity and overactivity of the internal anal sphincter (IAS) contributed to childhood IC. This was a prospective study of children who were admitted for investigation and treatment of chronic constipation at the gastrointestinal motility clinic in Guy's and St. Thomas' Hospital, NHS Foundation Trust, London. All children had a colonic transit marker study followed by anorectal manometry and anal endosonography under ketamine anesthesia. We used a validated symptom severity (SS) score questionnaire for assessment of constipation and fecal incontinence on admission to hospital and during follow-up for 12months. The SS score of 0 was the best and 65 the worst. Of 92 children, 57 were male and median (range) age was 8.46years (3.35-14.97). Duration of symptoms was 4.7years (0.3-13). Soiling was present in 88 (96%) patients, delay in defecation of once every 2 to 3days or less frequently in 86 (93%) and a palpable fecaloma (megarectum) on abdominal examination in 76 (83%). 42 children had 'fecal impaction' requiring disimpaction of stool from the rectum under general anesthesia and 50 had 'no impaction'. The median IAS resting pressure was within the normal range measuring 55mm Hg (25-107) and median amplitude and frequency of the IAS contractions were 10mm Hg (2.0-58) and 17cycles per min (5.0-34), respectively. The median IAS thickness was 0.93mm (0.5-2.0). There was no correlation between amplitude and frequency of anorectal contractions and anal sphincter resting pressure. The mean right colonic transit time was 8.55 (standard deviation ±13.22) h, left colonic transit time was 11.51h (±13.21), rectosigmoid transit time was 25.91h (±18.89) and total colonic transit time was 45.97h (±17.69). The anal sphincter resting pressure is normal in children with chronic IC. Increased frequency and amplitude of IAS contractions seen in these patients do not cause raised anal

    Sexual assault is a problem that permeates all socioeconomic classes and impacts hundreds of thousands in the United States and millions worldwide. Most victims do not report the assault; those that do often present to an emergency department. Care must encompass the patients' physical and emotional needs. Providers must be cognizant regarding handling of evidence and possible legal ramifications. This article discusses the emergency medicine approach to history taking, physical examination, evidence collection, chain of custody, psychological and medical treatment, and appropriate follow-up. Special circumstances discussed include intimate partner violence, male examinations, pediatric examinations, suspect examinations, and drug-facilitated assaults.

    The relevance of screening for airway obstruction in subjects not complaining of COPD symptoms may depend on the definition of airway obstruction. Response to exercise in asymptomatic subjects with persistent airway obstruction as defined by a postbronchodilator FEV1/FVC <5th centile lower limit of normal (LLN) remains unknown. Dyspnoea (Borg scale), exercise tolerance and ventilatory constraints on tidal volume expansion were assessed in 20 consecutive asymptomatic subjects with persistent mild airway obstruction detected by screening (postbronchodilator FEV1/FVC z-score: -2.14±0.29; FEV1 z-score: -1.02±0.64) undergoing incremental cycle cardiopulmonary exercise testing, compared with 20 healthy controls with normal spirometry matched for age, sex, body mass index and smoking history (FEV1/FVC z-score: -0.13±0.57; FEV1 z-score: 0.32±0.67) and with 20 symptomatic patients with COPD matched for the same characteristics (FEV1/FVC z-score: -2.36±0.51; FEV1 z-score: -1.02±0.48). Asymptomatic subjects with airway obstruction had higher dyspnoea ratings than controls during incremental exercise. Asymptomatic subjects with airway obstruction had also peak oxygen consumption and peak power output that were lower than controls, and similar to those observed in patients with COPD. Although less frequent than in COPD, dynamic hyperinflation was more frequent in asymptomatic subjects with airway obstruction than in controls (85%, 50% and 10%, respectively; p=0.01 in asymptomatic subjects vs controls and p=0.04 vs COPD). Although they did not present with chronic activity-related dyspnoea, subjects with a postbronchodilator FEV1/FVC

  3. Sexual excitement.

    Stoller, R J

    1976-08-01

    Sexual excitement depends on a scenario the person to be aroused has been writing since childhood. The story is an adventure, an autobiography disguised as fiction, in which the hero/heroine hides crucial intrapsychic conflicts, mysteries, screen memories of actual traumatic events and the resolution of these elements into a happy ending, best celebrated by orgasm. The function of the fantasy is to take these painful experiences and convert them to pleasure-triumph. In order to sharpen excitement-the vibration between the fear of original traumas repeating and the hope of a pleasurable conclusion this time-one introduces into the story elements of risk (approximations of the trauma) meant to prevent boredom and safety factors (sub-limnal signals to the storyteller that the risk are not truly dangerous). Sexual fantasy can be studied by means of a person's daydreams (including those chosen in magazines, books, plays, television, movies, and outright pornography), masturbatory behavior, object choice, foreplay, techniques of intercourse, or postcoital behavior.

    Perfectionism is a multidimensional personality characteristic that can affect all areas of life. This article presents the first systematic investigation of multidimensional perfectionism in the domain of sexuality exploring the unique relationships that different forms of sexual perfectionism show with positive and negative aspects of sexuality. A sample of 272 university students (52 male, 220 female) completed measures of four forms of sexual perfectionism: self-oriented, partner-oriented, partner-prescribed, and socially prescribed. In addition, they completed measures of sexual esteem, sexual self-efficacy, sexual optimism, sex life satisfaction (capturing positive aspects of sexuality) and sexual problem self-blame, sexual anxiety, sexual depression, and negative sexual perfectionism cognitions during sex (capturing negative aspects). Results showed unique patterns of relationships for the four forms of sexual perfectionism, suggesting that partner-prescribed and socially prescribed sexual perfectionism are maladaptive forms of sexual perfectionism associated with negative aspects of sexuality whereas self-oriented and partner-oriented sexual perfectionism emerged as ambivalent forms associated with positive and negative aspects.

    To report our 14 years experience with the laparoscopic-assisted anorectal pull-through (LAARP) for the treatment of male neonates with high imperforate anus. We reviewed all medical charts of patients who underwent LAARP from January 2001 to January 2015 collecting information regarding demographic data, associated anomalies, type of fistula, pelvic floor muscles tropism, surgery (operative time, conversion to open technique, and complications), and follow-up. Follow-up data were obtained through the use of validated questionnaires that aim to assess the intestinal function in terms of constipation and continence. At the Department of Pediatric Surgery of the University of Bologna, 13 male patients were operated in the study period (our protocol consisted of colostomy at birth followed by delayed LAARP). Mean age at operation was 4.75 months (range 1-14). There was one conversion to open technique due to a strong tension from the colostomy (this patient was excluded). Functional results were acceptable at a minimum 2-year-long follow-up. LAARP is a good choice for the correction of the high imperforate anus. Short-term outcomes are similar to those after posterior sagittal anorectoplasty (PSARP). Long-term outcomes should be better assessed.

    We report herein the case of a 64-year-old male who presented with hematochezia. The patient was diagnosed with malignant melanoma of the anorectum using colonoscopy. Preoperative studies revealed no distant metastases, and he underwent Miles operation. Pathological exams revealed that the tumor had invaded the submucosa with lymphatic and venous invasion. Cancer cells were found in regional lymph nodes. Post-operative CT scan demonstrated multiple metastases in the liver, and he received two courses of combined chemotherapy, DAV regimen (dacarbazine: DTIC 100 mg iv days 1-5, nimustine hydrochloride: ACNU 100 mg iv day 1, vincristine sulfate: VCR 1 mg iv day 1), leading to a complete response. However, malignant melanoma cells were found in hernia contents at the operation for left inguinal hernia, which led to a diagnosis of recurrent malignant melanoma. The patient has subsequently been well without any sign of recurrence including liver metastases. To our knowledge, this is the first report of a complete response in a patient with multiple liver metastases of anorectal malignant melanoma after DAV regimen.

    Background: High and intermediate types of anorectal malformations (ARMs) in male neonates may be managed either by primary neonatal reconstruction without colostomy cover or by traditional policy of staged reconstruction after neonatal colostomy. Posterior sagittal anorectoplasty (PSARP) is the current widely practiced reconstructive technique with varied results. Aim: To assess our functional results of PSARP without colostomy in male neonates with high and intermediate ARMs compared to 3-stage (neonatal colostomy – PSARP – colostomy closure) methodology in a high volume tertiary care institution of a developing country. Patients and Methods: The number of colostomies performed for male high/intermediate anomalies and the number of babies who completed 3-stage reconstruction during a 10-year period is analyzed. The outcome of primary neonatal PSARPs during the same period was analyzed. Eighty primary PSARPs were compared to 81 staged reconstructions for outcome analysis, using Kelly score. Results: A total of 453 colostomies were performed, but only 253 of them completed all stages of reconstruction (52%). Good continence was achieved in 45% of cases of primary PSARP versus 26% in 3-staged surgery. Conclusions: Primary PSARP in neonatal period without colostomy is a good option for high and intermediate ARMs in males if the treating surgeon is reasonably skilled in neonatal surgery and PSARP procedures.

    Vitamin B12 -peptide conjugates have considerable therapeutic potential through improved pharmacokinetic and/or pharmacodynamic properties imparted on the peptide upon covalent attachment to vitamin B12 (B12 ). There remains a lack of structural studies investigating the effects of B12 conjugation on peptide secondary structure. Determining the solution structure of a B12 -peptide conjugate or conjugates and measuring functions of the conjugate(s) at the target peptide receptor may offer considerable insight concerning the future design of fully optimized conjugates. This methodology is especially useful in tandem with constrained molecular dynamics (MD) studies, such that predictions may be made about conjugates not yet synthesized. Focusing on two B12 conjugates of the anorectic peptide PYY(3-36), one of which was previously demonstrated to have improved food intake reduction compared with PYY(3-36), we performed NMR structural analyses and used the information to conduct MD simulations. The study provides rare structural insight into vitamin B12 conjugates and validates the fact that B12 can be conjugated to a peptide without markedly affecting peptide secondary structure. © 2016 WILEY-VCH Verlag GmbH & Co.

    The ARM-Net (anorectal malformation network) consortium held a consensus meeting in which the classification of ARM and preoperative workup were evaluated with the aim of improving monitoring of treatment and outcome. The Krickenbeck classification of ARM and preoperative workup suggested by Levitt and Peña, used as a template, were discussed, and a collaborative consensus was achieved. The Krickenbeck classification is appropriate in describing ARM for clinical use. The preoperative workup was slightly modified. In males with a visible fistula, no cross-table lateral X-ray is needed and an anoplasty or (mini-) posterior sagittal anorectoplasty can directly be performed. In females with a small vestibular fistula (Hegar size <5 mm), a primary repair or colostomy is recommended; the repair may be delayed if the fistula admits a Hegar size >5 mm, and in the meantime, gentle painless dilatations can be performed. In both male and female perineal fistula and either a low birth weight (<2,000 g) or severe associated congenital anomalies, prolonged preoperative painless dilatations might be indicated to decrease perioperative morbidity caused by general anesthesia. The Krickenbeck classification is appropriate in describing ARM for clinical use. Some minor modifications to the preoperative workup by Levitt and Peña have been introduced in order to refine terminology and establish a comprehensive preoperative workup.

    Rectal atresia and anal stenosis are rare forms of anorectal malformations. The aim of the definitive surgical repair in such cases is to preserve the anal canal, the dentate line, and the sphincter complex. We present a case of rectal atresia and anal stenosis to demonstrate the differences in the operative repair. The techniques described leave the anterior wall of the very distal anal canal untouched in both rectal stenosis and anal atresia; however, the dissection of the rectum differs. The atretic rectum in rectal atresia is mobilized and sutured to the anal canal circumferentially. In anal stenosis, the posterior rectum is mobilized in the form of rectal advancement, and the posterior 180° is anastomosed directly to the skin (as in a standard PSARP) with preservation of the anal canal as the anterior 180° of the final anoplasty. These patients have an excellent prognosis for bowel control and fecal continence, and therefore, complete mobilization and resection of the anal canal must be avoided.

    The distribution of sphincter muscle complex in anorectal malformation (ARM) needs to be investigated on a case-by-case basis. This study was undertaken to demonstrate the differences in the anal sphincter muscles between patients with the same type of ARM. Computed tomography (CT) data from cases of high- and intermediate-type male patients with ARM were reviewed using three-dimensional (3D) image analysis. Twenty-seven male patients with ARM (18 high and 9 intermediate) before anorectoplasty were assessed using multidetector-row helical CT (MRH-CT). A 3D reconstruction was made using volume rendering method. The multi-dimensional sections of the 3D reconstructed images of the pelvic muscles were then analyzed and compared with schematic drawings from the literature. The sphincters in the high and intermediate types of ARM could be divided into five groups. In 13 out of 18 cases in the high type and 7 out of 9 cases in the intermediate type, images of the sphincter muscles appeared different from schematic drawings appearing in the literature. In both high and intermediate types of ARM, more than 2/3 of cases demonstrated unexpectedly displaced and deformed hypoplastic sphincters. Therefore, we recommend that variations in anal sphincter should be investigated on an individual basis prior to surgery.

  12. Asymptomatic Pulmonary Vein Stenosis: Hemodynamic Adaptation and Successful Ablation

    PubMed Central

    2016-01-01

    Pulmonary vein stenosis is a well-established possible complication following an atrial fibrillation ablation of pulmonary veins. Symptoms of pulmonary vein stenosis range from asymptomatic to severe exertional dyspnea. The number of asymptomatic patients with pulmonary vein stenosis is greater than originally estimated; moreover, only about 22% of severe pulmonary vein stenosis requires intervention. We present a patient with severe postatrial fibrillation (AF) ablation pulmonary vein (PV) stenosis, which was seen on multiple imaging modalities including cardiac computed tomography (CT) angiogram, lung perfusion scan, and pulmonary angiogram. This patient did not have any pulmonary symptoms. Hemodynamic changes within a stenosed pulmonary vein might not reflect the clinical severity of the obstruction if redistribution of pulmonary artery flow occurs. Our patient had an abnormal lung perfusion and ventilation (V/Q) scan, suggesting pulmonary artery blood flow redistribution. The patient ultimately underwent safe repeat atrial fibrillation ablation with successful elimination of arrhythmia. PMID:28105376

    Currently, age-specific recommendations for screening mammograms in asymptomatic women that have been developed by professional, voluntary, and governmental organizations differ. While there is strong epidemiologic evidence that mammographic screening in asymptomatic women aged 50 years or older reduces breast cancer mortality, the evidence for mortality reduction is not as clear for women aged 40 to 49 years. However, as described in this report, findings of further mortality and survival follow-up of subjects in earlier studies, as well as observations from more recent studies, suggest reductions in mortality and better survival in younger women as well. While mammography is currently the most effective method for detecting early breast cancers, some breast cancers may develop during the intervals between screening mammograms. The costs of mammographic screening also require consideration in the process of making national screening recommendations.

    The sacroiliac (SI) joints of 45 asymptomatic subjects were prospectively studied to define better the normal appearance of SI joints on CT scans and therby attach appropriate significance to CT signs of sacroiliitis. Joint space narrowing, subchondral sclerosis, erosions, ankylosis, osteophytes, subchondral cysts, and symmetry were evaluted. The results indicate that the SI joints demonstrate symmetry in patients under the age of 30 (100% of subjects in this age group). Those CT findings of sacroiliitis that occurred infrequently in the asymptomatic population, and hence may represent good indicators of sacroiliac disease, include increased sacral subchondral sclerosis in subjects under the age of 40 (11%), bilateral or unilateral uniform joint space of less than 2 mm (2% or 0%, respectively), erosions (2%), and intraarticular ankylosis (0%).

    Human rotavirus isolates from 1100 stool samples were analyzed by polyacrylamide gel electrophoresis, and 48 different migration patterns were detected. Heterogeneity in the migration of segment 10 was observed in both long and short electropherotypes in which three long and two short patterns were identified. In spite of these variations all short and long electropherotypes were subgrouped by enzyme immunoassay as subgroups I and II respectively. Mixed infections were detected in 17% of cases and the subgrouping correlated with the corresponding electropherotypes. The same electropherotypes were present in severe, mild and asymptomatic cases and no electropherotype was particularly associated with greater virulence. Furthermore, the electropherotypes isolated from nosocomial asymptomatic cases were the same as those detected from those admitted with severe diarrhea. It seems unlikely that electropherotyping can be used to identify more virulent strains of rotavirus. Images Fig. 1 Fig. 3 PMID:1847104

    Congenital sternal defects are rare deformities frequently associated with other anomalies of the chest wall and other organ systems. Although pectus excavatum, pectus carinatum, and cleft sternum can present as isolated deformity, in most cases they are associated with heart and inner organs anomalies and described as symptoms of syndromes like Marfan syndrome, Noonan syndrome, Poland anomaly, and Cantrell pentalogy. In contrast, the etiology of an isolated defect is not well understood. We observed a short sternum (dysmorphic manubrium, hypoplastic body, and complete absence of the xiphoid process) in a completely asymptomatic 13-year-old woman. A comprehensive instrumental exams panel was performed to exclude associated anomalies of the heart and of the other organ systems. The patient was completely asymptomatic and she did not need any medical or surgical treatment. To our knowledge, this is the first case of isolated short sternum reported in literature.

    Influenza infection manifests in a wide spectrum of severity, including symptomless pathogen carriers. We conducted a systematic review and meta-analysis of 55 studies to elucidate the proportional representation of these asymptomatic infected persons. We observed extensive heterogeneity among these studies. The prevalence of asymptomatic carriage (total absence of symptoms) ranged from 5.2% to 35.5% and subclinical cases (illness that did not meet the criteria for acute respiratory or influenza-like illness) from 25.4% to 61.8%. Statistical analysis showed that the heterogeneity could not be explained by the type of influenza, the laboratory tests used to detect the virus, the year of the study, or the location of the study. Projections of infection spread and strategies for disease control require that we identify the proportional representation of these insidious spreaders early on in the emergence of new influenza subtypes or strains and track how this rate evolves over time and space.

    To determine prenatal methods to predict and prevent spontaneous preterm birth in asymptomatic twin pregnancies. Articles were searched using PubMed, Embase and Cochrane library. Uterine activity monitoring and bacterial vaginosis screening are not useful to predict preterm birth (EL2 and EL3 respectively). Current literature data are contradictory and insufficient to determine whether fetal fibronectin and digital cervical assessment are predictors of preterm birth. History of preterm birth (EL4), and cervical length measurement by transvaginal ultrasonography (EL2) predict preterm birth. Nevertheless, there are no intervention studies that have evaluated cervical length measurement in the prevention of preterm birth. Hospital bedrest, prophylactic tocolytic and progesterone therapy, and prophylactic cervical cerclage in patients with or without short cervix have not been shown to be effective in preventing preterm birth. Prenatal methods to prevent spontaneous preterm birth in asymptomatic twin pregnancies are currently very limited. Copyright © 2009 Elsevier Masson SAS. All rights reserved.

Considering the impaired immunity of CKD patients, the relevance of infection in peritoneal dialysis (PD), and the increased prevalence of parasites in CKD patients, protozoa colonization was evaluated in PD effluent from CKD patients undergoing PD. Overnight PD effluent was obtained from 49 asymptomatic stable PD patients. Protozoa analysis was performed microscopically by searching cysts and trophozoites in direct wet mount of PD effluent and after staining smears. Protozoa were found in PD effluent of 10.2% of evaluated PD patients, namely Blastocystis hominis, in 2 patients, and Entamoeba sp., Giardia sp., and Endolimax nana in the other 3 patients, respectively. None of these patients presented clinical signs or symptoms of peritonitis at the time of protozoa screening. Our results demonstrate that PD effluent may be susceptible to asymptomatic protozoa colonization. The clinical impact of this finding should be further investigated.

    With the current popularity of physical fitness, the family physician is often asked to advise asymptomatic individuals who wish to undertake an exercise program. In the majority of cases, adequate assessment consists of a thorough history and physical examination, along with a few simple investigations, including a resting electrocardiogram. Exercise stress testing of asymptomatic individuals produces an unacceptably high frequency of false-positive results, and its use should be restricted to those patients with cardiac symptoms or major cardiac risk factors. The potential benefits of a longterm commitment to regular exercise should be discussed with the patient and guidance provided on the optimal form of exercise program for that individual. Exercise must not be considered in isolation. Other major cardiovascular risk factors should be sought and dealt with appropriately. PMID:21286106

    Chlamydia trachomatis causes acute non-gonococcal urethritis, but some infected men are asymptomatic. We examined leukocytes in uncentrifuged first-voided urine (FVU) from asymptomatic men at high risk for chlamydial infection by automated urine particle analyzers to assess whether the quantification of urinary leukocytes could predict chlamydial infection in these men. We enrolled 209 asymptomatic men, whose female sexual partners had been diagnosed as having a genital chlamydial infection. Their FVU specimens were examined for quantification of leukocytes with automated urine particle analyzers and tested for Neisseria gonorrhoeae, C. trachomatis, Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma parvum, and Ureaplasma urealyticum by nucleotide acid amplification tests. Eleven men positive for N. gonorrhoeae or M. genitalium were excluded from further analysis. In the remaining 198 men, 84 positive for C. trachomatis (42.4%) had 1.8-1666.9 white blood cells (WBCs)/μl (median, 43.3 WBCs/μl) in their FVU, whereas 114 negative for C. trachomatis had 0.1-1378 WBCs/μl (median, 4.8 WBCs/μl). A receiver operating characteristic (ROC) curve was constructed to examine the sensitivity and specificity of leukocytes counts for predicting chlamydial infection. A cut-off point of leukocyte counts of 12.5 WBCs/μl was determined from the ROC curve, resulting in a sensitivity of 86.9% and specificity of 88.6% for predicting chlamydial infection. Leukocyte quantification in FVU by automated urine particle analyzers showed good performance in predicting the positivity and negativity for chlamydial infection in asymptomatic men. This test could potentially develop into a relevant tool for preselecting asymptomatic men prior to C. trachomatis screening.

    Many methods are used to detect urethral Neisseria gonorrhea (NG) infection among asymptomatic men who have sex with men (MSM). The objective of this study was to define the performance of conventional culture compared to real-time polymerase chain reaction (PCR) for diagnosis of asymptomatic urethral gonorrhea among MSM. In this cross-sectional study, 147 clinical specimens for NG testing from asymptomatic participants were evaluated. MSM >18 years old who consented to undergo urethral swab and collection of urine samples from two clinics (one was the sexually transmitted diseases (STDs) mobile clinic and the second was the antiretroviral clinic) located in Khon Kaen, Thailand, were recruited. For conventional culture, 147 swab specimens from urethra were analyzed. For real-time PCR, the same samples and collected urine (147 urethral swab and 62 urine) were evaluated. Participants were predominately older aged (mean age: 28.79 years, range: 18-54), asymptomatic (99.3%), and engaged in sex with multiple partners (63% had at least two partners and 36% had at least three partners during the previous 3 months). Twenty-five MSM (17%) had history of STD, mainly human immunodeficiency virus infection. Of the 147 specimens, 42 were positive for NG detected by real-time PCR (prevalence: 28.6%, 95% confidence interval [CI]: 24.8%-32.4%), while none of the 147 MSM were positive for NG detected by conventional culture (prevalence: 0.0%, 95% CI: 0.0%-7.3%). These findings indicated that conventional culture had low sensitivity but high specificity (0.0% and 100%, respectively). We could not demonstrate that many of the factors that were identified in other studies were associated to increased (or decreased) risk of urethral gonococcal infection in our population. In asymptomatic MSM, nucleic acid amplification tests are more appropriate for screening of urethral NG infection than conventional culture. However, the culture method is necessary for monitoring emerging

    In Europe, human infections with "Candidatus Neoehrlichia mikurensis" have mainly been restricted to immunocompromised patients. We report here the first cases of asymptomatic "Ca. Neoehrlichia mikurensis" infection in immunocompetent humans (5/316 [1.6%] were infected). Due to the potential threats of infections with "Ca. Neoehrlichia mikurensis" in healthy persons to the safety of the blood supply, further study of this phenomenon is required.

    The gross majority of extramedullary plasmacytomas arise in the lymphatic tissue of the upper respiratory tract. On average, one third of patients with a solid plasmacytoma will develop multiple myeloma, resulting in a worse clinical outcome. We describe a case of rapid recurrent extramedullary plasmacytomas in the background of an asymptomatic multiple myeloma. A 71-year-old, white Caucasian woman presented with three extramedullary plasmacytomas occurring within a short time period. The third plasmacytoma was accompanied by progressive cervical pain and swallow dysfunction. Additional immunostaining test results were negative for CD56 and showed high MIB-1 expression in the extramedullary plasmacytoma and low MIB-1 expression in the bone marrow. A conventional swallow X-ray did not show any obstruction, however a magnetic resonance imaging scan of her cervical backbone revealed an extramedullary plasmacytoma, threatening her spinal cord. A short course of radiation therapy alleviated her pain and during almost a two-year follow-up period, the multiple myeloma remained asymptomatic, despite the rise in immunoglobulin A lambda levels. After the appearance of the third plasmacytoma, systemic chemotherapy was started to prevent the development of a fourth plasmacytoma, despite the asymptomatic character of the multiple myeloma. In this case report we describe the rapid appearance of extramedullary plasmacytomas in the background of an asymptomatic multiple myeloma. An immunohistochemical analysis was negative for CD56 and showed high MIB-1 expression in the extramedullary plasmacytoma and low MIB-1 expression in the bone marrow, contributing to the potential underlying pathophysiology of the recurrent extramedullary plasmacytomas and their genetic changes. Systemic chemotherapy was started and no fourth extramedullary plasmacytoma has developed since.

    We report the extremely rare case of a 73-year-old asymptomatic patient who has an isolated true parachute mitral valve (PMV). In the echocardiographic examination, the parasternal long-axis view showed a single papillary muscle. The short-axis view revealed the presence of a symmetric mitral valve orifice with all chordae attaching to a large anterolateral papillary muscle. Because detailed examination did not reveal the presence of other complications, this patient was diagnosed as an isolated true PMV.

    A parachute deformity of an atrioventricular valve occurs when the chordae tendineae arise from one papillary muscle or muscle group. Sometimes, the normal number of papillary muscles is seen, but one muscle is much larger than its peers and shows some characteristic features. This is known as a parachute-like asymmetric valve and has been well described in the mitral position. We present a young, asymptomatic adult with an abnormal tricuspid valve possessing typical features of a parachute-like asymmetric valve.

    2014-01-01

    Background. Clostridium difficile infection (CDI) incidence has increased dramatically over the last decade. Recent studies suggest that asymptomatic carriers may be an important reservoir of C. difficile in healthcare settings. We sought to identify the prevalence and risk factors for asymptomatic C. difficile carriage on admission to the hospital. Methods. Patients admitted to Barnes-Jewish Hospital without diarrhea were enrolled from June 2010 through October 2011. Demographic information and healthcare and medication exposures 90 days prior to admission were collected. Stool specimens or rectal swabs were collected within 48 hours of admission and stored at −30°C until cultured. Clostridium difficile isolates were typed and compared with isolates from patients with CDI. Results. A stool/swab specimen was obtained for 259 enrolled subjects on admission. Two hundred four (79%) were not colonized, 40 (15%) had toxigenic C. difficile (TCD), and 15 (6%) had nontoxigenic C. difficile. There were no differences between TCD-colonized and -uncolonized subjects for age (mean, 56 vs 58 years; P = .46), comorbidities, admission from another healthcare facility (33% vs 24%; P = .23), or recent hospitalization (50% vs 50%; P = .43). There were no differences in antimicrobial exposures in the 90 days prior to admission (55% vs 56%; P = .91). Asymptomatic carriers were colonized with strains similar to strains from patients with CDI, but the relative proportions were different. Conclusions. There was a high prevalence of TCD colonization on admission. In contrast to past studies, TCD colonization was not associated with recent antimicrobial or healthcare exposures. Additional investigation is needed to determine the role of asymptomatic TCD carriers on hospital-onset CDI incidence. PMID:24755858

    Norovirus (NoV) is a major cause of nonbacterial acute gastroenteritis worldwide in all age groups, and asymptomatic individuals may contribute to NoV transmission as a reservoir. Nonetheless, little information is available regarding asymptomatic NoV infection in Indonesia. We performed an epidemiological analysis of NoV infection among asymptomatic healthy volunteers in the city of Surabaya, Indonesia (population ~2.75 million). A total of 512 stool samples from 18 individuals (age range 20-42years) collected from July 2015 to June 2016 were examined. The detection of NoV and the genotype classification were carried out by a reverse transcription-polymerase chain reaction (RT-PCR) direct sequencing method. NoV was detected in 14 of the 512 stool samples (2.7%), with 7 individuals (38.9%) having at least 1 positive stool sample. All 14 of the NoV strains detected belonged to genogroup GII. The phylogenetic analysis indicated that 10 strains (71.4%) were grouped with GII.2, 2 (14.3%) were GII.17, 1 was GII.4 Sydney 2012, and 1 was GII.1. The circulation of GII.Pg/GII.1 and GII.Pe/GII.4 Sydney 2012 recombinant variants was detected among an asymptomatic population in Surabaya, Indonesia. Of the 7 positive individuals, 2 were repeatedly infected with the same strain and heterogenous strains. Taken together, our results suggest that the excretion of NoV from healthy individuals is one of the sources of NoV outbreak. Copyright © 2017 Elsevier B.V. All rights reserved.

    Ovarian cancer is frequent and recurrence happens in about 75% of patients. As it presents high rates of relapse, the exams for this diagnosis are widely discussed. Beside this, there have been discussions about benefits for early anatomic diagnosis and whether endoscopic ultrasound (EUS) can be used to track the relapse of the disease. We present a case, in which anatomic location and histological definition of an asymptomatic recurrence of the ovarian cancer was misdiagnosed with conventional methods, but was possible through EUS.

    Objective The objective of this study was to explore the useful of vestibular evoked myogenic potential (VEMP) testing for detecting endolymphatic hydrops, especially in the second ear of patients with unilateral Ménière disease (MD). Methods This study was performed at a tertiary care academic medical center. Part I consisted of postmortem temporal bone specimens from the temporal bone collection of the Massachusetts Eye & Ear Infirmary; part II consisted of consecutive consenting adult patients (n = 82) with unilateral MD by American Academy of Otolaryngology–Head and Neck Surgery criteria case histories. Out-come measures consisted of VEMP thresholds in patients and histologic saccular endolymphatic hydrops in postmortem temporal bones. Results Saccular hydrops was observed in the asymptomatic ear in six of 17 (35%) of temporal bones from donors with unilateral MD. Clinic patients with unilateral MD showed elevated mean VEMP thresholds and altered VEMP tuning in their symptomatic ears and, to a lesser degree, in their asymptomatic ears. Specific VEMP frequency and tuning criteria were used to define a “Ménière-like” response. This “Ménière-like” response was seen in 27% of asymptomatic ears of our patients with unilateral MD. Conclusions Bilateral involvement is seen in approximately one third of MD cases. Saccular hydrops appears to precede symptoms in bilateral MD. Changes in VEMP threshold and tuning appear to be sensitive to these structural changes in the saccule. If so, then VEMP may be useful as a detector of asymptomatic saccular hydrops and as a predictor of evolving bilateral MD. PMID:16735912

    2010-01-01

    Liver hydatidosis is the most common clinical presentation of cystic echinococcosis (CE). Ultrasonographic mass surveys have demonstrated the true prevalence, including the asymptomatic characteristic of the majority of cases, providing new insight into the natural history of the disease. This raises the question of whether to treat or not to treat these patients, due to the high and unsuspected prevalence of CE. The high rate of liver/lung frequencies of cyst localization, the autopsy findings, and the involution of cysts demonstrated in long time follow-up of asymptomatic carriers contribute to this discussion. The decision to treat an asymptomatic patient by surgery, albendazole, or puncture aspiration injection and reaspiration or to wait and watch, is based on conflicting reports in the literature, the lack of complications in untreated patients over time, and the spontaneous disappearance and involution of cysts. All these points contribute to difficulties of individual clinical decisions. The patients should be informed of the reasons and the risks of watchful/waiting without treatment, the possibility of complications, and the risks of the other options. As more information on the natural history of liver hydatidosis is acquired, selection of the best treatment will be come easier. Without this knowledge it would be very difficult to establish definitive rules of treatment. At present, it is possible to manage these patients over time and to wait for the best moment for treatment. Follow-up studies must be conducted to achieve this objective. PMID:20806427

    Huanglongbing (HLB) is a bacterial infection of citrus trees transmitted by the Asian citrus psyllid Diaphorina citri. Mitigation of HLB has focused on spraying of insecticides to reduce the psyllid population and removal of trees when they first show symptoms of the disease. These interventions have been only marginally effective, because symptoms of HLB do not appear on leaves for months to years after initial infection. Limited knowledge about disease spread during the asymptomatic phase is exemplified by the heretofore unknown length of time from initial infection of newly developing cluster of young leaves, called flush, by adult psyllids until the flush become infectious. We present experimental evidence showing that young flush become infectious within 15 d after receiving an inoculum of Candidatus Liberibacter asiaticus (bacteria). Using this critical fact, we specify a microsimulation model of asymptomatic disease spread and intensity in a grove of citrus trees. We apply a range of psyllid introduction scenarios to show that entire groves can become infected with up to 12,000 psyllids per tree in less than 1 y, before most of the trees show any symptoms. We also show that intervention strategies that reduce the psyllid population by 75% during the flushing periods can delay infection of a full grove, and thereby reduce the amount of insecticide used throughout a year. This result implies that psyllid surveillance and control, using a variety of recently available technologies, should be used from the initial detection of invasion and throughout the asymptomatic period.

    Glial cysts of the pineal gland are benign and mostly asymptomatic incidental lesions found in the brain MRI or at autopsy examinations. In rare cases pineal cysts become symptomatic and require surgical intervention. Symptomatic glial cysts may be clinically and radiologically indistinguishable from cystic neoplasms of the pineal region; therefore, histopathological diagnosis is critical for further prognosis and therapy in operated patients. In this paper we present detailed histopathological characteristics of symptomatic glial cysts in 2 surgical cases and of asymptomatic cysts of the pineal gland found at random in 3 autopsy cases. Both surgical patients, a 19-year-old girl and a 17-year-old boy, presented with severe headaches, associated with syncope in one case and insomnia in the second one. Preoperative MR imaging suggested tumour of the pineal gland in case no. 2. Histopathological and immunohistochemical examination of the specimens from both surgical and all autopsy cases revealed a characteristic pattern of cystic structures within the pineal gland, surrounded by layers of a dense fibrillar glial tissue and pineal parenchyma, consistent with non-neoplastic glial cysts. Although histopathological findings in asymptomatic and symptomatic cysts are essentially the same, the cyst in surgical case 1 was unilocular and partly lined with ependymal cells, whereas the cysts in other cases were multilocular, comprising cavities of various size, formed in the central part of gliotic tissue or directly within the pineal parenchyma, and lacked ependymal lining. Possible pathophysiological and clinicopathological significance of some morphological variants of pineal glial cysts is discussed.

    Background. Bacterial airway colonization is known to alter the airway mucosa immune response in neonates whereas the impact of viruses is unknown. The objective was therefore to examine the effect of respiratory viruses on the immune signature in the airways of asymptomatic neonates. Methods. Nasal aspirates from 571 asymptomatic 1-month-old neonates from the Copenhagen Prospective Studies on Asthma in Childhood 2010 birth cohort were investigated for respiratory viruses. Simultaneously, unstimulated airway mucosal lining fluid was obtained and quantified for levels of 20 immune mediators related to type 1, type 2, type 17, and regulatory immune paths. The association between immune mediator levels and viruses was tested by conventional statistics and partial least square discriminant analysis. Results. Picornaviruses were detected in 58 neonates (10.2%) and other viruses in 10 (1.8%). A general up-regulation of immune mediators was found in the neonates with picornavirus (P < .0001; partial least square discriminant analysis). The association was pronounced for type 1– and type 2–related markers and was unaffected by comprehensive confounder adjustment. Detection of picornavirus and bacteria was associated with an additive general up-regulating effect. Conclusions. Asymptomatic presence of picornavirus in the neonatal airway is a potent activator of the topical immune response. This is relevant to understanding the immune potentiating effect of early life exposure to viruses. PMID:26655299

    Detection and treatment of asymptomatic bacteriuria (ASB) in pregnancy is important to avert the attendant maternal and fetal morbidity. Other than urine culture, no other screening test is unequivocal. The use of enhanced urinalysis test to detect ASB in pregnancy was investigated. This was a prospective observational study which compared enhanced urinalysis with dipstick tests and urine culture. Clean catch midstream urine specimen was collected from 150 consecutive asymptomatic pregnant women. Tests of validity were used for comparison. Enhanced urinalysis detected bacteriuria as much as urine culture (4% vs. 4.7%). Itwas 57.1% sensitive and 98.6% specific. It had a false negative rate of 42.9% and was 96.7% accurate when compared to urine culture. Enhanced urinalysis took 1-2 hours to be done and required skills to use the microscope and was more expensive than dipstick urinalysis. The accuracy of enhanced urinalysis and its ability to detect ASB as much as urine culture connotes that it can be used to detect asymptomatic bacteriuria in pregnancy albeit only in secondary and tertiary health centres because of the cost and technicality involved.

    Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the digestive tract. Approximately two thirds of clinically manifest tumors occur in the stomach, nearly one third in the small bowel, and the rest in the colorectal region with a few cases in the esophagus. GIST originate within the smooth muscle layer in the wall of the tubular gastrointestinal tract and grow mostly toward the serosa, far less often toward the mucosa. In the latter case, ulceration may develop and can cause gastrointestinal bleeding as the cardinal symptom. However, most GIST of the stomach are asymptomatic. They are increasingly detected incidentally as small intramural or submucosal tumors during endoscopy and particularly during endoscopic ultrasound. Epidemiological and molecular genetic findings suggest that early asymptomatic GIST of the stomach (< 1 cm) show self-limiting tumorigenesis. Thus, early (< 1 cm) asymptomatic gastric GIST (synonym: micro-GIST) are found in 20%-30% of the elderly. The mostly elderly people with early gastric GIST have an excellent GIST-specific prognosis. Patients with early GIST of the stomach can therefore be managed by endoscopic surveillance. PMID:25031785

    Currently, it is unclear whether asymptomatic recurrent reactivations of herpes simplex virus type 1 (HSV-1) occur in the central nervous systems of infected people, and if these events could lead to a progressive deterioration of neuronal function. In this context, HSV-1 constitutes an important candidate to be included among the risk factors for the development of neuropathies associated with chronic neuroinflammation. The aim of this study was to assess in vivo inflammatory and neurodegenerative markers in the brain during productive and latent HSV-1 infection using a mouse model of herpes simplex encephalitis. Neuroinflammation and neurodegeneration markers were evaluated in mice trigeminal ganglia and cerebral cortex during HSV-1 infection, by immunohistochemistry, western blot, and RT-PCR. Neuronal ICP4 viral antigen expression indicative of a reactivation episode during asymptomatic latency of HSV-1 infection in mice was accompanied by upregulation of neuroinflammatory (toll-like receptor-4, interferon α/β, and p-IRF3) and early neurodegenerative markers (phospho-tau and TauC3). HSV-1 reactivation from latency induced neuroinflammatory and neurodegenerative markers in the brain of asymptomatic mice suggesting that recurrent reactivations could be associated with cumulative neuronal dysfunctions.

    Neurocysticercosis (NC), a parasitic disease caused by Taenia solium, may be either asymptomatic or have mild to severe symptoms due to several factors. In this study, the immunological factors that underlie NC pleomorphism were studied. Ten of the 132 inhabitants of a rural community in Mexico (Tepez) had a computerized tomography (CT) scan compatible with calcified NC, and all were asymptomatic. Their immunological profiles were compared with those of 122 CT scan negative (non-NC) subjects from the same village. NC was associated with a TH2 response (IgG4, IL-4, IL-5, IL-13). Subjects from Tepez had higher levels of specific antibodies (IgG1, IgG2, IgG4, IgE) and specific cell proliferation than subjects from an area with low exposure (Ensenada). This suggests that non-NC subjects from Tepez had been exposed to T. solium and resisted infection in the brain. Distinct immunological profiles in equally exposed individuals differing in outcome of infection support the hypothesis of host-related factors in resistance to and pathogenesis of NC. This is the first study reporting the immunological profile associated with the asymptomatic form of NC.

    Osteolysis around a cementless acetabular component can lead to severe bone loss. This study examined whether osteolysis should be treated while still asymptomatic. Thirty-seven liner cementation revisions were performed in 34 patients. Mean patient age was 61 years, and mean time elapsed after index surgery was 85 months (range, 36-168 months). Patients were evaluated by Harris Hip Score (HHS), and mean follow-up was 5 years (range, 43-82 months). Average HHS was 87 with a pain component of 39. In asymptomatic patients, both the HHS and the pain score were significantly higher: 95 and 43, respectively (P<.01). One patient with extensive bone loss had a fracture of the acetabulum and underwent revision at another institution. Revision of the polyethylene liner and cementation of a new one is a useful technique in patients with a stable acetabular shell. This is especially true for asymptomatic patients with osteolysis and thus should be performed early; however, high dislocation rate is still a concern.

    Lichen sclerosus (LS) is a chronic inflammatory condition that is known to arise on the vulva. Many women with LS report vulvar pain, often affecting a patient's quality of life. In this study, the sexual function of LS patients, with and without pain, was compared to control populations. A case-control study to examine the relationship between LS and sexual dysfunction was conducted. A total of 335 women presenting to the gynecology clinic were included in the study: 197 women with biopsy confirmed LS were compared to two control groups (95 asymptomatic women were "healthy" controls and 43 women had vulvovaginal candidiasis) on self-reported current health complaints, medical and surgical history and current symptoms such as pain and itching, type and frequency of sexual activity, and satisfaction with sexual activity. Women with LS reported less frequent sexual activity than healthy controls (p=0.007) and Candida controls (p=0.04). Currently sexually active women with LS were significantly less likely to report vaginal intercourse (71.6%) than healthy controls (89.0%, p=0.003) or Candida controls (100%, p=0.0003), even though similar proportions of all three groups reported that vaginal intercourse was important. Satisfaction towards the quality of current sexual activity was significantly lower among women with LS compared with both the healthy and Candida control groups. 23.7% of women with LS reported that sexual activity was rarely or never satisfactory as compared with 0% of healthy controls (p<0.0001) and 6.5% of Candida controls (p=0.03). Women with LS have less frequent sexual activity and less satisfying sexual activity when compared with controls.

    Federal, state, and local laws in the US now govern almost every aspect of sexuality. This includes sexuality at the workplace, sexuality education, adolescent sexuality, access to sexuality information and sexually explicit materials, sexual orientation, and sexually transmitted disease(STD)/HIV transmission. Almost 33% of the US Supreme Court's docket this past term concerned sexuality issues. In contrast to 50 years ago, when sexuality law was confined to the criminal arena, contemporary "sex crimes" primarily relate to nonconsensual and exploitative behaviors. It is time for lawmakers, judges, lawyers, policy analysts, lobbyists, and advocates to realize they cannot legislate or litigate how, when, or why people fall in love. Rather, the role of the law should be to create and preserve models of justice and equality that seek to preserve one's individual rights to privacy and freedom to choose in matters related to one's sexuality. This includes free access to age-appropriate sexuality information, the right to marriage and children regardless of sexual orientation, comprehensive sexuality education that encompasses information about avoiding unwanted pregnancies and HIV/STDs, access to contraception and abortion, protection from sexually abusive or exploitative relationships, and access to sexual health care.

    Sexual orientation has been defined as the patterns of sexual thoughts, fantasies, and attractions that an individual has toward other persons of the same or opposite gender. Throughout childhood and approaching adolescence, children try to understand their own sexuality and sexual orientation in the context of the society in which they live. Typically, this attempt to understand first occurs in thoughts of a sexual nature and later through actions, usually before sexual orientation is clearly defined. How these experiences are handled, by the individual and close friends and relatives, helps to define how an individual views and accepts their sexual orientation ultimately as an adult.

    Following the recent medical innovations, it is now possible to disassociate sexuality and reproduction. With contraception, people can have free sexuality without the fear of an unexpected pregnancy. Frequently, Assisted Reproductive Technologies (ART), with in vitro fertilization, can obtain a pregnancy without intercourse. There are three major problems concerning infertility and sexuality. Firstly, infertility because of a sexual disorder; secondly, sexual disorder induced by infertility diagnosis; thirdly, sexual disorder induced by ART. Praticians should be aware of possible existence of sexual problems to allow the couple to express them. Once diagnosed, these troubles can be treated by the pratician himself or the couple has to be referred to a psychologist or a sexologist.

    Asymptomatic bacteriuria occurs in 5% to 10% of pregnancies and, if left untreated, can lead to serious complications. To assess which antibiotic is most effective and least harmful as initial treatment for asymptomatic bacteriuria in pregnancy. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (March 2010) and reference lists of retrieved studies. Randomized controlled trials comparing two antibiotic regimens for treating asymptomatic bacteriuria. Review authors independently screened the studies for inclusion and extracted data. We included five studies involving 1140 women with asymptomatic bacteriuria. We did not perform meta-analysis; each trial examined different antibiotic regimens and so we were not able to pool results. In a study comparing a single dose of fosfomycin trometamol 3 g with a five-day course of cefuroxime, there was no significant difference in persistent infection (risk ratio (RR) 1.36, 95% confidence interval (CI) 0.24 to 7.75), shift to other antibiotics (RR 0.08, 95% CI 0.00 to 1.45), or in allergy or pruritus (RR 2.73, 95% CI 0.11 to 65.24). A comparison of seven-day courses of 400 mg pivmecillinam versus 500 mg ampicillin, both given four times daily, showed no significant difference in persistent infection at two weeks or recurrent infection, but there was an increase in vomiting (RR 4.57, 95% CI 1.40 to 14.90) and women were more likely to stop treatment early with pivmecillinam (RR 8.82, 95% CI 1.16 to 66.95). When cephalexin 1 g versus Miraxid(R) (pivmecillinam 200 mg and pivampicillin 250 mg) were given twice-daily for three days, there was no significant difference in persistent or recurrent infection. A one- versus seven-day course of nitrofurantoin resulted in more persistent infection with the shorter course (RR 1.76, 95% CI 1.29 to 2.40), but no significant difference in symptomatic infection at two weeks, nausea, or preterm birth. Comparing cycloserine with sulphadimidine, no significant differences in

    The susceptibility of the Iberian ibex (Capra pyrenaica) to Mycoplasma conjunctivae ocular infection and the changes in their interaction over time were studied in terms of clinical outcome, molecular detection, and IgG immune response in a captive population that underwent a severe infectious keratoconjunctivitis (IKC) outbreak. Mycoplasma conjunctivae was detected in the Iberian ibex, coinciding with the IKC outbreak. Its prevalence had a decreasing trend in 2013 that was consistent with the clinical resolution (August, 35.4%; September, 8.7%; November, 4.3%). Infections without clinical outcome were, however, still detected in the last handling in November. Sequencing and cluster analyses of the M. conjunctivae strains found 1 year later in the ibex population confirmed the persistence of the same strain lineage that caused the IKC outbreak but with a high prevalence (75.3%) of mostly asymptomatic infections and with lower DNA load of M. conjunctivae in the eyes (mean quantitative PCR [qPCR] cycle threshold [CT ], 36.1 versus 20.3 in severe IKC). Significant age-related differences of M. conjunctivae prevalence were observed only under IKC epizootic conditions. No substantial effect of systemic IgG on M. conjunctivae DNA in the eye was evidenced with a linear mixed-models selection, which indicated that systemic IgG does not necessarily drive the resolution of M. conjunctivae infection and does not explain the epidemiological changes observed. The results show how both epidemiological scenarios, i.e., severe IKC outbreak and mostly asymptomatic infections, can consecutively occur by entailing mycoplasma persistence.IMPORTANCEMycoplasma infections are reported in a wide range of epidemiological scenarios that involve severe disease to asymptomatic infections. This study allows a better understanding of the transition between two different Mycoplasma conjunctivae epidemiological scenarios described in wild host populations and highlights the ability of M

    The aim of this study was to analyze the outcome of males with HARM treated with a laparoscopic-assisted anorectal pull-through compared with the open posterior sagittal approach in a single institution. This study includes 32 patients: 17 (9 with a rectoprostatic fistula [RPF] and 8 with a rectovesical fistula [RVF]) who underwent laparoscopic-assisted anorectal pull-through from October 2001 onward and 15 (8 with an RPF and 7 with an RVF) treated by posterior sagittal approach before that date. Patients were reviewed retrospectively but were operated on by the authors and had longitudinal follow-up. Parameters analyzed included associated anomalies, sacral ratio (SR) index, age at surgery, operative time, complications, presence of voluntary bowel movements, constipation, and soiling. A good outcome was determined by absent or grade 1 soiling and a poor outcome result by soiling grades 2 and 3. Mean age at surgery was 22 and 37.5 months for patients with RPF and RVF, respectively, in the laparoscopic group and 29.2 and 25.7 months in the open group. Operative time was significantly shorter (P < .0036) for the laparoscopic RVF repair compared with the open approach. In patients with RPF, 50% in the laparoscopic (L) and 37.5% in the open (O) approach had an SR below 0.6. Fifty percent of all patients with RVF had an SR below 0.6, making groups comparable in terms of evaluating bowel function. Four patients were excluded in the analysis of functional results. Voluntary bowel movements with previous defecatory sensation were present in 83.l3% (5/6) in L vs 87.5% (7/8) in O patients with RPF and 62.5% (5/8) L vs 50% (3/6) in O patients with RVF. Grade 1 soiling was present in 50% (3/6) vs 62.5% (5/8) of patients with RPF and 37.5% (3/8) vs 16% (1/6) of patients with RVF in the L and O groups, respectively. Soiling grade 2 or 3 was present in 50% (3/6) vs 12.5% (1/8) of patients with RPF and 37.5% (3/8) vs 50% (3/6) of patients with RVF in the L and O groups

    Women experience multiple changes in social and reproductive statuses across the life span which can affect sexual functioning. Various phases of the sexual response cycle may be impacted and can lead to sexual dysfunction. Screening for sexual problems and consideration of contributing factors such as neurobiology, reproductive life events, medical problems, medication use, and depression can help guide appropriate treatment and thereby improve the sexual functioning and quality of life of affected women. Treatment options include psychotropic medications, hormone therapy, and psychotherapy.

    Anorectal malformations (ARMs) comprise a broad spectrum of conditions ranging from mild anal anomalies to complex cloacal malformations. In 40-50% of cases, ARM occurs within the context of defined genetic syndromes or complex multiple congenital anomalies, such as VATER/VACTERL (vertebral defects [V], ARMs [A], cardiac defects [C], tracheoesophageal fistula with or without esophageal atresia [TE], renal malformations [R], and limb defects [L]) association. Here, we report the identification of deletions at chromosome 13q using single nucleotide polymorphism-based array analysis in two patients with mild ARM as part of VATER/VACTERL and VATER/VACTERL-like associations. Both deletions overlap the previously defined critical region for ARM. Heterozygous Efnb2 murine knockout models presenting with mild ARM suggest EFNB2 as an excellent candidate gene in this region. Our patients showed a mild ARM phenotype, closely resembling that of the mouse. We performed a comprehensive mutation analysis of the EFNB2 gene in 331 patients with isolated ARM, or ARM as part of VATER/VACTERL or VATER/VACTERL-like associations. However, we did not identify any disease-causing mutations. Given the convincing argument for EFNB2 as a candidate gene for ARM, analyses of larger samples and screening of functionally relevant non-coding regions of EFNB2 are warranted. In conclusion, our report underlines the association of chromosome 13q deletions with ARM, suggesting that routine molecular diagnostic workup should include the search for these deletions. Despite the negative results of our mutation screening, we still consider EFNB2 an excellent candidate gene for contributing to the development of ARM in humans.

  17. Sexuality and Islam.

    This paper deals with three major questions: (1) What are the sexual norms defined by the sacred texts (Koran and Sunna)? (2) What are the sexual practices currently observed among Moslems? (3) To which extent are current sexual practices of Moslems dissociated from Islamic sexual norms? Sexual standards in Islam are paradoxical: on the one hand, they allow and actually are an enticement to the exercise of sexuality but, on the other hand, they discriminate between male and female sexuality, between marital and pre- or extramarital sexuality, and between heterosexuality and homosexuality. Men are given more rights with regard to the expression of their sexuality; women are forbidden to have extramarital sex (with their slaves) and both genders to have homosexual relationships. The combination of these paradoxical standards with modernisation leads to the current back and forth swing of sexual practices between repression and openness. Partial modernisation leads to greater sexual tolerance. But restrictive sexual standards have gathered strength and have become idealised as a result of the current radicalisation of Islam. This swing of the pendulum between repression and openness is illustrated by phenomena such as public harassment, premarital sexuality, female pleasure, prostitution, and homosexuality. Currently, Islam is not any more the only reference which provides guidance concerning sexual practices but secularisation of sexual laws is still politically unthinkable today. So the only solution is to achieve reform in the name of Islam, through the reinterpretation of repressive holy texts.

    BACKGROUND AND METHODS--The absence of any official statistics on the prevalence of STD in homosexual men in Spain induced us to carry out a prospective study of new homosexual patients who consulted the STD Clinic of the School of Medicine in Seville, between January 1988 and December 1989. The aim of the study was to determine the prevalence of symptomatic and asymptomatic infections in this group of patients. RESULTS--1805 patients were seen during the study period; 318 patients were homosexual of whom 309 agreed to participate in the study. Of the 309 homosexual men, 108 (35%) had symptoms and the remaining 201 (65%) were asymptomatic. In the symptomatic group the diagnoses were: syphilis 28 (25.9%); urethritis 40 (37%) (of these 40, 11 had Neisseria gonorrhoeae, five had Chlamydia trachomatis, five had Ureaplasma urealyticum, one had Herpes simplex virus and in 18 no pathogen was detected); genital herpes seven (6.4%). Eleven (10%) had concomitant infections. The following infections were found in the asymptomatic group: syphilis 23 (11.4%), N gonorrhoeae six (3%), C trachomatis two (1%), Herpes simplex virus one (0.5%). Antibodies against HIV were detected in 30 (9.6%) of the total group. CONCLUSIONS--Sexually transmitted diseases are common amongst homosexual men in Seville and many of these are asymptomatic.

    There is a need for state-of-the-art information in the area of sexually transmitted infections (STIs) in relation to sexual function. There are an estimated 60 million people living with and 340 million with treatable STIs. Surveys show sexual problems to be as high as 35% for men and 55% for women; however, there is little research directly assessing relationships between infection and sexual function. To show that STIs are associated with (and may cause) sexual dysfunction. Conversely, sexual dysfunction can increase patients' risk of STI acquisition. In men, erectile dysfunction (ED) associated with condom use may lead to unsafe sexual practices and, hence, STI acquisition. The role of various therapies including phosphodiesterase type 5 inhibitors in the treatment of ED in positive men taking social drugs will be explored. To provide state-of-the-art knowledge concerning sexual function and STIs, representing the opinions of five experts from four countries developed in a consensus process and encompassing a detailed literature review over a 2-year period. Expert opinion was based on the grading of evidence-based medical literature, widespread internal committee discussion, public presentation, and debate. This article highlights major factors causing the spread of STIs and suggests management interventions to prevent further spread of HIV/STIs, focusing on the juxtaposition between STIs and sexual functioning. Women's unique vulnerabilities to HIV/STIs (biological and physiological issues, gender-based violence, gender inequity) and their impact on women's sexual function are reviewed. Similarly, men's unique vulnerabilities to HIV/STIs including condom use, disclosure, voluntary counseling and testing, multiple concurrent sexual partners, and recreational drug use--particularly in homosexual men--are explored, as is the association of prostatitis and sexual function. Lastly, the article reviews the relationship between circumcision and sexual dysfunction. A

    1998-01-01

    BACKGROUND: Hepatitis C virus (HCV) is the cause of almost all cases of parenterally transmitted non-A, non-B viral hepatitis (NANBH). HCV is an RNA virus, unrelated to the hepatitis viruses, A, B, D, or E; it was first identified in 1989. Although most infections become chronic, and it may lead to chronic liver disease, most patients with HCV infection are asymptomatic. The predominant modes of transmission are by blood, blood products, or other parenteral exposure, particularly injecting drug use. More contentious is the role of sexual transmission, although evidence for this was provided by studies of NANBH. OBJECTIVE: This review considers the evidence for sexual transmission, and the types of studies used to estimate the rate of transmission and the factors that may influence it. METHOD: A Medline search using the keywords hepatitis C, sex, transmission, and prevalence in MeSH and free text. References in papers were searched, and some unpublished data identified. References were further selected to illustrate different methodologies. FINDINGS: Evidence for sexual transmission is provided by several types of study including prevalence studies in groups at risk of other STDs, investigation of cases identified from surveillance reports, and cross sectional and longitudinal partner studies. Many studies are limited by their small size, the sensitivity and specificity of early assays, lack of controls, or the difficulty of excluding other routes of transmission. One prospective cohort study reported an incidence of 12 per 1000 person years in the sexual partners of HCV infected patients. 1-3% of partners of HCV infected patients are found to be infected in cross sectional studies. Co-infection with HIV, duration of the relationship, or chronic liver disease may be independent cofactors increasing the risk of transmission. A meta-analysis of selected studies may be informative, and further larger prospective studies are required. There is a small but definite risk

    During gestation, hyperphagia is necessary to cope with the metabolic demands of embryonic development. There were three main aims of this study: Firstly, to investigate the effect of pregnancy on hypothalamic fatty acid metabolism, a key pathway for the regulation of energy balance; secondly, to study whether pregnancy induces resistance to the anorectic effect of fatty acid synthase (FAS) inhibition and accumulation of malonyl-coenzyme A (CoA) in the hypothalamus; and, thirdly, to study whether changes in hypothalamic AMPK signaling are associated with brown adipose tissue (BAT) thermogenesis during pregnancy. Our data suggest that in pregnant rats, the hypothalamic fatty acid pathway shows an overall state that should lead to anorexia and elevated BAT thermogenesis: decreased activities of AMP-activated protein kinase (AMPK), FAS, and carnitine palmitoyltransferase 1, coupled with increased acetyl-CoA carboxylase function with subsequent elevation of malonyl-CoA levels. This profile seems dependent of estradiol levels but not prolactin or progesterone. Despite the apparent anorexic and thermogenic signaling in the hypothalamus, pregnant rats remain hyperphagic and display reduced temperature and BAT function. Actually, pregnant rats develop resistance to the anorectic effects of central FAS inhibition, which is associated with a reduction of proopiomelanocortin (POMC) expression and its transcription factors phospho-signal transducer and activator of transcription 3, and phospho-forkhead box O1. This evidence demonstrates that pregnancy induces a state of resistance to the anorectic and thermogenic actions of hypothalamic cellular signals of energy surplus, which, in parallel to the already known refractoriness to leptin effects, likely contributes to gestational hyperphagia and adiposity.

    Food contamination by the trichothecene mycotoxin deoxynivalenol (DON, vomitoxin) has the potential to adversely affect animal and human health by suppressing food intake and impairing growth. In mice, the DON-induced anorectic response results from aberrant satiety hormone secretion by enteroendocrine cells (EECs) of the gastrointestinal tract. Recent in vitro studies in the murine STC-1 EEC model have linked DON-induced satiety hormone secretion to activation of calcium-sensing receptor (CaSR), a G-coupled protein receptor, and transient receptor potential ankyrin-1 (TRPA1), a TRP channel. However, it is unknown whether similar mechanisms mediate DON's anorectic effects in vivo. Here, we tested the hypothesis that DON-induced food refusal and satiety hormone release in the mouse are linked to activation of CaSR and TRPA1. Oral treatment with selective agonists for CaSR (R-568) or TRPA1 (allyl isothiocyanate (AITC)) suppressed food intake in mice, and the agonist's effects were suppressed by pretreatment with corresponding antagonists NPS-2143 or ruthenium red (RR), respectively. Importantly, NPS-2143 or RR inhibited both DON-induced food refusal and plasma elevations of the satiety hormones cholecystokinin (CCK) and peptide YY3-36 (PYY3-36); cotreatment with both antagonists additively suppressed both anorectic and hormone responses to DON. Taken together, these in vivo data along with prior in vitro findings support the contention that activation of CaSR and TRPA1 contributes to DON-induced food refusal by mediating satiety hormone exocytosis from EEC.

    OBJECTIVE To determine whether a 3-year-old girl, brought to an after-hours clinic because her mother was concerned, had been assaulted by her father during a weekend visit. SOURCES OF INFORMATION MEDLINE was searched using the key words child, sexual assault/abuse, and expectations. Recent textbooks on childhood sexual assault and abuse were consulted. The secondary-level regional pediatric sexual assault clinic’s experience over 1 year was reviewed. Articles in the literature generally provide level II evidence. MAIN MESSAGE The literature review and the clinic’s experience both indicated that specialty centres for child sexual assault and abuse rarely produce positive physical findings that conclusively confirm or rule out sexual assault, especially when children are asymptomatic and not in an acute state. Primary care practitioners can use a brief history and physical examination to decide on the next level of care and determine the urgency of referral. Urgent assessment of children thought to have been abused or assaulted is required when children disclose assault (especially with genital-genital contact or ejaculation); when children have acute pain, bleeding, or discharge; when results of a physician’s examination are abnormal; or when parents are extremely distressed. CONCLUSION Family physicians have a pivotal role in evaluation of childhood sexual assault or abuse. Knowledge of the outcomes of evaluation is crucial to understanding when and how to refer.

    Surgical treatment of anorectal malformations (ARMs) and Hirschsprung's disease (HD) leads to alterations in bowel habits and fecal incontinence, with consequent quality of life impairment. The objectives were to create and validate a Questionnaire for the Fecal Incontinence Index (FII) based on the Holschneider score, as well as a Questionnaire for the Assessment of Quality of Life Related to Fecal Incontinence in Children and Adolescents (QQVCFCA), based on the Fecal Incontinence Quality of Life. The questionnaires were applied to 71 children submitted to surgical procedure, in two stages. Validity was tested by comparing the QQVCFCA and a generic quality of life questionnaire (SF-36), and between QQVCFCA and the FII. A group of 59 normal children was used as control. At two stages, 45.0% (32/71) and 42.8% (21/49) of the patients had fecal incontinence. It was observed that the QQVCFCA showed a significant correlation with the SF-36 and FII (Pearson's correlation 0.57), showing that the quality of life is directly proportional to improvement in fecal incontinence. Quality of life in patients with fecal incontinence is still globally impaired, when compared with control subjects (p<0.05, Student's t test). There were also significant differences between the results of children with ARMs and children with HD. QQVCFCA and FII are useful tools to assess the quality of life and fecal incontinence in these groups of children. Children with ARMs submitted to surgical procedure and HD have similar quality of life impairment. Copyright © 2015 Sociedade de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda.

    OBJECTIVE The goal of this study was to determine the significance of spinal cord anomalies (SCAs) in patients with anorectal malformations (ARMs) by comparing the outcomes for bowel function, lower urinary tract symptoms (LUTS), and lower-limb neurological abnormalities to these outcomes in patients with similar ARMs and a normal spinal cord. METHODS The spinal cord MRI records of female patients treated for vestibular and perineal fistula (VF/PF) and male patients with rectourethral fistula (RUF) at a single center between 1983 and 2006 were reviewed. Bowel function and LUTS were assessed by questionnaire. Patients with extensive sacral anomalies or meningomyelocele were excluded. RESULTS Of 89 patients (median age 15 years, range 5-29 years), MRI was available in 90% (n = 80; 40 male patients with RUF), and 80% of patients returned the questionnaire (n = 64; 31 male patients with RUF). Spinal cord anomalies were found in 34%, comprising a filum terminale lipoma in 30%, low conus medullaris in 10%, and thoracolumbar syrinx in 6%. Bowel functional outcomes between patients with SCAs (n = 23) and those with a normal spinal cord (n = 41) were not significantly different for soiling (70% vs 63%), fecal accidents (43% vs 34%), and constipation (57% vs 39%; p = not significant for all). The LUTS, including urge (65% vs 54%), urge incontinence (39% vs 24%), stress incontinence (17% vs 22%), and straining (32% vs 29%) were also comparable between groups (p = not significant for all). No patients developed lower-limb neurological abnormalities. CONCLUSIONS The results suggest that the long-term functional outcomes for patients with SCAs who had VF/PF and RUF may not differ significantly from patients with the same type of ARMs and a normal spinal cord. The results favor a conservative approach to their management in the absence of abnormal neurological findings in the lower limbs.

    Background Rats maintained on a ketogenic diet (KD; 80% fat, 15% protein, 5% carbohydrate) have increased adiposity and leptin as compared to chow-fed controls (CH; 16% fat, 19% protein, 65% carbohydrate), although body weights and daily caloric intakes do not differ. Methods Rats maintained on a KD or CH were assessed for responsivity to intraperitoneal (i.p.) or intracerebroventricular (i.c.v.) leptin. Hypothalamic gene expression was evaluated to determine the effects of KD on proopiomelanocortin (POMC) mRNA expression and components of the leptin-signaling system. Results Caloric intake by KD rats was decreased at a lower dose of i.p. leptin (100 μg) than was required to reduce intake by CH rats (leptin, caloric intake was reduced in KD rats as compared to intake following i.p. saline; p < 0.05). In a separate experiment to evaluate responsivity to i.c.v. leptin, the minimal dose of leptin required to significantly reduce 24-hour caloric intake did not differ between the groups. In the arcuate nucleus, POMC mRNA was elevated after a lower dose of i.c.v. leptin in KD rats (5 μg) than was required to increase POMC mRNA expression in CH rats (15 μg) or reduce caloric intake in either group. Finally, evaluation of the level of phosphorylated STAT3 (pSTAT3) in the arcuate and SOCS3 mRNA in the hypothalamus revealed significantly more pSTAT3-positive cells and increased SOCS3 mRNA expression at baseline for KD rats, compared to CH, neither of which was further increased following i.p. leptin administration. Conclusion These data demonstrate that despite increased adiposity, leptin and markers of leptin resistance, responsivity to the anorectic effects of exogenous leptin is retainable during maintenance on a KD.

    There is growing interest in the effects of exercise on plasma gut hormone levels and subsequent energy intake (EI) but the effects of mode and exercise intensity on anorectic hormone profiles on subsequent EI remain to be elucidated. We aimed to investigate whether circulating peptide YY(3-36) (PYY(3-36)) and glucagon-like peptide-1 (GLP-1 or GCG as listed in the HUGO Database) levels depend on exercise intensity, which could affect subsequent EI. Ten young male subjects (mean+/-s.d., age: 23.4+/-4.3 years, body mass index: 22.5+/-1.0 kg/m(2), and maximum oxygen uptake (VO(2 max)): 45.9+/-8.5 ml/kg per min) received a standardized breakfast, which was followed by constant cycling exercise at 75% VO(2 max) (high intensity session), 50% VO(2 max) (moderate intensity session), or rest (resting session) for 30 min. At lunch, a test meal was presented, and EI was calculated. Blood samples were obtained during three sessions for measurements of glucose, insulin, PYY(3-36), and GLP-1, which includes GLP-1 (7-36) amide and GLP-1 (9-36) amide. Increases in blood PYY(3-36) levels were dependent on the exercise intensity (effect of session: P<0.001 by two-way ANOVA), whereas those in GLP-1 levels were similar between two different exercise sessions. Of note, increase in area under the curve values for GLP-1 levels was negatively correlated with decrease in the EI in each exercise session (high: P<0.001, moderate: P=0.002). The present findings raise the possibility that each gut hormone exhibits its specific blood kinetics in response to two different intensities of exercise stimuli and might play differential roles in regulation of EI after exercise.

    To determine whether the extent of surgery is associated with survival in anorectal malignant melanoma (ARMM). ARMM is a rare and highly malignant neoplasm with unfavorable prognosis. The optimal surgical management, abdominoperineal resection (APR) or local excision (LE), has been long debated, but conclusive evidence has not been obtained. A comprehensive electronic literature search was performed to identify studies evaluating survival between APR and LE for ARMM. The main outcome measures were overall survival, relapse-free survival, and local recurrence. A meta-analysis was performed using the random-effects models to calculate the odds ratios (ORs) and 95% confidence intervals (CIs). Thirty-one studies, with a total of 1006 patients [544 (54.1%) APR and 462 (45.9%) LE], were included. Meta-analyses showed that overall survival (OR, 1.14; 95% CI, 0.74-1.76; P = 0.54) and relapse-free survival (OR, 0.95; 95% CI, 0.43-2.09; P = 0.89) did not differ significantly between the APR and LE groups. APR significantly reduced local recurrence compared with LE (OR, 0.18; 95% CI, 0.09-0.36; P < 0.00001). Although several limitations, such as inclusion of only retrospective studies with relatively small sample size and selection biases for surgical procedure, are involved, this meta-analysis suggested that APR has no survival benefit; however, APR confers better local control than LE. Given that local failures after LE could be managed by salvage surgery, minimizing morbidity and maximizing quality of life should be the focus in surgical treatment of ARMM.

    Anorectal malformations (ARMs) are a major congenital anomaly in neonates. There is significant geographical variation in the birth prevalence varying from 1:1,500 to 1:5,000 live births. There is no published literature on the birth prevalence of ARM occurring within the referral area for The University of Witwatersrand tertiary hospitals in South Africa. Retrospective data were collected from the Pediatric Surgical Department, University of the Witwatersrand. Patient records for a 6-year period from January 2005 to December 2010 were obtained from Chris Hani Baragwanath Academic Hospital and Charlotte Maxeke Johannesburg Academic Hospital. The number of live births per year for a specific municipal district was obtained from the National Department of Health. The χ(2) test for trend test was used to determine statistically significance. The birth prevalence for ARM in 2010 was shown to be 1:3,989 live births (2.5/10,000 live births) for the University of Witwatersrand tertiary hospital referral area. A statistically significant overall increase in the birth prevalence of ARM from January 2005 till December 2010 was demonstrated (p < 0.0001). The municipal districts of Johannesburg (p = 0.0015) and Ekurhuleni (p = 0.0066) revealed the greatest increase in birth prevalence. This study has provided current statistics on the birth prevalence of ARM in the University of Witwatersrand tertiary hospital referral area, as well as demonstrating a positive incremental trend in the occurrence of this condition over a 6-year period. Future studies will examine the birth prevalence in several other provinces of South Africa. Results from the collective data will then be used to form conclusions regarding any regional or national changes in the birth prevalence of ARM as well as to identify any epidemiological trends.

    The clinical utility of monoamine releasers such as phenmetrazine or d-amphetamine as candidate agonist medications for cocaine dependence is hindered by their high abuse liability. Phendimetrazine is a clinically available schedule III anorectic that functions as a prodrug for phenmetrazine and thus may have lower abuse liability. This study determined the effects of continuous 14-day treatment with phendimetrazine on cocaine vs. food choice in rhesus monkeys (N=4). Responding was maintained under a concurrent schedule of food delivery (1-g pellets, fixed-ratio 100 schedule) and cocaine injections (0-0.1mg/kg/injection, fixed-ratio 10 schedule). Cocaine choice dose-effect curves were determined daily before and during 14-day periods of continuous intravenous treatment with saline or (+)-phendimetrazine (0.32-1.0mg/kg/h). Effects of 14-day treatment with (+)-phenmetrazine (0.1-0.32 mg/kg/h; N=5) and d-amphetamine (0.032-0.1mg/kg/h; N=6) were also examined for comparison. During saline treatment, food was primarily chosen during availability of low cocaine doses (0, 0.0032, and 0.01 mg/kg/injection), and cocaine was primarily chosen during availability of higher cocaine doses (0.032 and 0.1mg/kg/injection). Phendimetrazine initially decreased overall responding without significantly altering cocaine choice. Over the course of 14 days, tolerance developed to rate decreasing effects, and phendimetrazine dose-dependently decreased cocaine choice (significant at 0.032 mg/kg/injection cocaine). Phenmetrazine and d-amphetamine produced qualitatively similar effects. These results demonstrate that phendimetrazine can produce significant, though modest, reductions in cocaine choice in rhesus monkeys. Phendimetrazine may be especially suitable as a candidate medication for human studies because of its schedule III clinical availability. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    A previous Cochrane systematic review has shown that antibiotic drug treatment of asymptomatic bacteriuria in pregnant women substantially decreases the risk of pyelonephritis and reduces the risk of preterm delivery. However, it is not clear whether single-dose therapy is as effective as longer conventional antibiotic treatment. To assess the effects of different durations of treatment for asymptomatic bacteriuria in pregnancy. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 August 2015) and reference lists of identified articles. Randomized and quasi-randomized trials comparing antimicrobial therapeutic regimens that differed in duration (particularly comparing single dose with longer duration regimens) in pregnant women diagnosed with asymptomatic bacteriuria. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. We assessed the quality of the evidence using the GRADE approach. We included 13 studies, involving 1622 women. All were comparisons of single-dose treatment with short-course (four- to seven-day) treatments. The risk of bias of trials included in this review was largely unclear, and most trials were at high risk of performance bias. The quality of the evidence was assessed using the GRADE approach. When the any antibiotic agent was used, the 'no cure' rate for asymptomatic bacteriuria in pregnant women was slightly lower for the short-course treatment over the single-dose treatment, although there was evidence of statistical heterogeneity (average risk ratio (RR) 1.28, 95% confidence interval (CI) 0.87 to 1.88; women = 1502, studies = 13; I² = 56%; very low quality evidence). Data from only good quality trials also showed better cure rates with short (four- to seven-day) regimens of the same microbial agent (average RR 1.72, 95% CI 1.27 to 2.33; women = 803, studies = two; I² = 0%; high quality evidence). There was no clear difference in the

    Despite indirect evidence linking narcissism to sexual aggression, studies directly examining this relationship have yielded inconsistent results. Likely contributing to such inconsistencies, prior research has used global measures of narcissism not sensitive to whether the components of narcissism are activated in sexual versus non-sexual domains. The current research avoided such problems by using a measure of sexual narcissism to predict sexual aggression. In a sample of 299 men and women, Study 1 validated the Sexual Narcissism Scale, a new sexuality research instrument with four subscales—Sexual Exploitation, Sexual Entitlement, Low Sexual Empathy, and Sexual Skill. Then, in a sample of 378 men, Study 2 demonstrated that sexual narcissism was associated with reports of the frequency of sexual aggression, three specific types of sexual aggression (unwanted sexual contact, sexual coercion, and attempted/completed rape), and the likelihood of future sexual aggression. Notably, global narcissism was unrelated to all indices of sexual aggression when sexual narcissism was controlled. That sexual narcissism outperformed global assessments of narcissism to account for variance in sexual aggression suggests that future research may benefit by examining whether sexual narcissism and other sexual-situation-specific measurements of personality can similarly provide a more valid test of the association between personality and other sexual behaviors and outcomes (e.g., contraceptive use, infidelity, sexual satisfaction).

    Computed tomography (CT) screening of lung cancer allows the detection of early tumors. The objective of our study was to verify whether initial asymptomatic lung cancers, identified by high-resolution low-dose CT (LD-CT) on a high-risk population, show genetic abnormalities that could be indicative of the early events of lung carcinogenesis. We analyzed 78 tumor samples: 21 (pilot population) from heavy smokers with asymptomatic non-screening detected early-stage lung cancers and 57 from 5203 asymptomatic heavy smoker volunteers, who underwent a LD-CT screening study. During surgical resection of the detected tumors, tissue samples were collected and short-term cultures were started for karyotype evaluation. Samples were classified according to the normal (NK) or aneuploid (AK) karyotype. The NK samples were further analyzed by the Affymetrix single-nucleotide polymorphisms (SNPs) technology. Metaphase spreads were obtained in 73.0% of the selected samples: 80.7% showed an AK. A statistically significant correlation was found between presence of vascular invasion and abnormal karyotype. A total of 10 NK samples were suitable for SNPs analysis. Subtle genomic alterations were found in eight tumors, the remaining two showing no evidence to date of chromosomal aberrations anywhere in the genome. Two common regions of amplification were identified at 5p and 8p11. Mutation analysis by direct sequencing was conducted for the K-RAS, TP53 and EGFR genes, confirming data already described for heavy smokers. We show that: (i) the majority of screening-detected tumors are aneuploid; (ii) early-stage tumors tend to harbor a less abnormal karyotype; (iii) whole genome analysis of NK tumors allows for the detection of common regions of copy number variation (such as amplifications at 5p and 8p11), highlighting genes that might be considered candidate markers of early events in lung carcinogenesis.

    To characterize the rotator cable high-resolution ultrasound appearance in asymptomatic shoulders of volunteers of different age. IRB approval and volunteers' written consent was obtained. Excluding subjects with known shoulder affections, we screened 24 asymptomatic volunteers. Supraspinatus and infraspinatus tendons high-resolution ultrasound evaluation was performed according to standard scan protocols, further excluding shoulders with partial/full-thickness cuff tears. Thus, we studied 24 shoulders in 12 young volunteers (age range 21-39 years, mean age 33 ± 8 years) and 21 shoulders in 11 elderly volunteers (age range 62-83 years, mean age 75 ± 45 years). For each shoulder, we noted rotator cable visibility and its thickness and width. Fisher's and U Mann-Whitney statistics were used. Rotator cable was less frequently detected in young than in elderly volunteers (5/24 vs. 11/21 shoulders; P = 0.034). When detected, rotator cable was significantly thicker in young (range 1.2-1.5 mm, mean thickness 1.3 ± 0.1 mm) than in elderly (range 0.9-1.4 mm, mean thickness 1.2 ± 0.1 mm) volunteers (P = 0.025), while its width was not significantly different in young (range 4.5-7.1 mm, mean 5.6 ± 1.1 mm) compared to elderly (range 2.5-7.1 mm, mean 4.2 ± 1.4 mm) volunteers (P = 0.074) although a tendency can be highlighted. Ultrasound demonstrated the different consistency of rotator cable in young and elderly asymptomatic patients, with high interobserver reproducibility.

  17. Education, individual time preferences, and asymptomatic disease detection.

    Asymptomatic conditions such as hypertension are generally hard to diagnose, absent routine medical examinations. This is especially problematic in developing countries, where most citizens do not engage in routine examinations due to limited economic resources. We study the roles of education and individual time preferences in asymptomatic disease detection and management. Using discrete choice models on a sample of 4209 hypertensive Indonesian adults surveyed between November 2007 and April 2008, we find that both education and individual time preferences play important roles. However, the effects are different for people in good health than they are for people in bad health. Education does not seem to matter for disease detection when respondents are in good general health, and its effects on disease management vary largely in magnitudes between these groups. In terms of disease detection, more educated respondents have a higher probability of being diagnosed, but only conditional on being in poor general health. Time preferences, on the other hand, matter for respondents in good general health, but the effect is not significant for those in bad health. More impatient respondents that are in good health have a higher probability of being under-diagnosed because they are more likely to forgo routine physicals. The findings point to two distinct channels through which education can affect health, and suggest that different types of policies need to be implemented, in order to reach the entire population. Traditional programs that stimulate education and improve the socio-economic status of individuals in developing countries are helpful, but they do not address the whole problem. Besides its more usual positive effects, education can also negatively affect the health of asymptomatic patients, because it reflects a higher opportunity cost of engaging in preventative health screenings.

  18. Is Asymptomatic Vasospasm Associated With Poor Outcome in Subarachnoid Hemorrhage?

    Background: Vasospasm occurs in up to 70% of aneurysmal subarachnoid hemorrhage (aSAH), but only half becomes symptomatic. It is unclear whether asymptomatic vasospasm (AV) detected by noninvasive testing affects outcome. Prophylactic hemodilutional, hypertensive, and hypervolemic (HHH) therapy is widely used but the benefit remains unproven. We aim to determine whether AV increases the risk of poor outcome and whether HHH is safe. Methods: A total of 175 consecutive patients with aSAH without clinical vasospasm were included. Patients with sonographic (transcranial doppler) or radiologic (computed tomography [CT] Angiography) vasospasm were assigned to AV group, while those without were assigned to no vasospasm (NV) group. Logistic regression was used to determine the association between AV and HHH on poor outcome, defined as modified Rankin scale (mRS) >3 at discharge or 3 to 6 months' follow-up. Results: In all, 106 patients had NV and 25 received HHH. A total of 69 patients had AV and 54 received HHH. Asymptomatic vasospasm compared to NV was not associated with poor outcome (odds ratio [OR] 2.6, 95% confidence interval [CI]: 0.75-8.9; P = .1). Hemodilutional, hypertensive, and hypervolemic use in patients with AV did not improve the outcome (OR 0.16, 95%CI: 0.009-2.84; P = .2). In patients with NV, HHH use showed trend toward poor outco
